The new lifestyle included factors affecting both energy intake and energy consumption, and it is now thought that weight gain during the lockdown was the result of complex effects. The aim of this study was to determine the relationships among lifestyle habits, laboratory data, and body weight gain during the lockdown using medical check-up data. Methods: A total of 3789 individuals who had undergone consecutive medical check-ups during the period from 2018 to 2020 were included in this study. Participants whose body weight had increased by 5% or more were divided into two groups: a before-lockdown group (participants who had gained weight between 2018 and 2019) and an after-lockdown group (participants who had gained weight between 2019 and 2020). Physical measurements, laboratory data, and answers to six questions about lifestyle habits, for which information was obtained from the records from medical check-ups, were compared in the two groups. Results: There was no significant difference between the distribution of weight changes in 2018-2019 before the lockdown and the distribution of weight changes in 2019-2020 after the lockdown. The before-lockdown and after-lockdown groups both included about 7% of the total participants (279 and 273 participants, respectively). Diastolic blood pressure and levels of AST, ALT, and LDL-C were significantly higher in the after-lockdown group than in the before-lockdown group. The percentages of participants with alcohol consumption and exercise habits were significantly higher in the after-lockdown group than in the before-lockdown group, and an analysis by gender showed that the differences were significant for women but not for men. Conclusions: The distributions of weight changes before and during the COVID-19 pandemic were similar. Exercise habits and alcohol consumption might have been unique factors causing weight gain during the COVID-19 pandemic, particularly in women. Our findings suggest that the impact of behavioral restrictions and lifestyle changes during a pandemic may be different in men and women. en-copyright= kn-copyright= en-aut-name=NishidaChisa en-aut-sei=Nishida en-aut-mei=Chisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=COVID-19 pandemic kn-keyword=COVID-19 pandemic en-keyword=lockdown kn-keyword=lockdown en-keyword=weight gain kn-keyword=weight gain en-keyword=medical check-ups kn-keyword=medical check-ups en-keyword=lifestyle kn-keyword=lifestyle END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=6 article-no= start-page=064502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Josephson effect and odd-frequency pairing in superconducting junctions with unconventional magnets en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider Josephson junctions formed by coupling two conventional superconductors via an unconventional magnet and investigate the formation of Andreev bound states, their impact on the Josephson effect, and the emergent superconducting correlations. In particular, we focus on unconventional magnets known as 𝑑-wave altermagnets and 𝑝-wave magnets. We find that the Andreev bound states in 𝑑-wave altermagnet and 𝑝𝑦-wave magnet Josephson junctions strongly depend on the transverse momentum, with a spin splitting and low-energy minima as a function of the superconducting phase difference 𝜑. In contrast, the Andreev bound states for 𝑝𝑥-wave magnets are insensitive to the transverse momentum. We then show that the Andreev bound states can be probed by the local density of states in the middle of the junction, which also reveals that 𝑑𝑥2−𝑦2- and 𝑝-wave magnet junctions are prone to host zero energy peaks. While the zero-energy peak in 𝑑𝑥2−𝑦2-wave altermagnet junctions tends to oscillate with the magnetic order, it remains robust in 𝑝-wave magnet junctions. We then discover that the Josephson current in 𝑑-wave altermagnet junctions is composed of higher harmonics of 𝜑, which originate a 𝜙-Josephson junction behavior entirely controlled by the magnetic order in 𝑑𝑥⁢𝑦-wave altermagnets. In contrast, the Josephson current in Josephson junctions with 𝑝-wave magnets exhibits a conventional sinelike profile with a fast sign change at 𝜑=𝜋 due to zero-energy Andreev bound states. We also demonstrate that the critical currents in 𝑑-wave altermagnet Josephson junctions exhibit an oscillatory decay with the increase of the magnetic order, while the oscillations are absent in 𝑝-wave magnet junctions albeit the currents exhibit a slow decay. Furthermore, we also demonstrate that the interplay of the Josephson effect and unconventional magnetic order of 𝑑-wave altermagnets and 𝑝-wave magnets originates from odd-frequency spin-triplet 𝑠-wave superconducting correlations that are otherwise absent. Our results can serve as a guide to pursue the new functionality of Josephson junctions based on unconventional magnets. en-copyright= kn-copyright= en-aut-name=FukayaYuri en-aut-sei=Fukaya en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaKazuki en-aut-sei=Maeda en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YadaKeiji en-aut-sei=Yada en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CayaoJorge en-aut-sei=Cayao en-aut-mei=Jorge kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYukio en-aut-sei=Tanaka en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LuBo en-aut-sei=Lu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Environmental Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Department of Physics and Astronomy, Uppsala University kn-affil= affil-num=5 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=6 en-affil=Center for Joint Quantum Studies, Tianjin Key Laboratory of Low Dimensional Materials Physics and Preparing Technology, Department of Physics, Tianjin University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=47 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate Effects of a Single Home-based Rehabilitation Treatment on Balance Performance and Toe-Grip Strength in Elderly Subjects Continuing the Same Rehabilitation Program en-subtitle= kn-subtitle= en-abstract= kn-abstract=We assessed the immediate effects of a home-based rehabilitation (HBR) program on the balance performance and toe-grip strength of 29 older adults (mean±SD age of 75.1±9.9; 16 males, 13 females) who were participating in HBR services provided by Japan’s nursing care insurance system. Their toe-grip strength and balance performance were measured before and after the HBR program. The subjects’ toe-grip strength was significantly improved after the treatment. The subjects who had had a stroke showed a significant improvement after HBR. Contrarily, no significant difference was observed in the subjects’ functional reach results or their one-leg standing time. These results indicate that the exercise regimen provided in the HBR program led to increased excitability of motor units and immediately enhanced the subjects’ toe-grip strength. en-copyright= kn-copyright= en-aut-name=KojimaKazunori en-aut-sei=Kojima en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UjikawaTakuya en-aut-sei=Ujikawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoToshiro en-aut-sei=Ono en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physical Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Rehabilitation, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Occupational Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= en-keyword=home-based rehabilitation kn-keyword=home-based rehabilitation en-keyword=toe-grip strength kn-keyword=toe-grip strength en-keyword=balance performance kn-keyword=balance performance END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=1 article-no= start-page=46 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Terpolymerization reactions of epoxides, CO2, and the third monomers toward sustainable CO2-based polymers with controllable chemical and physical properties en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carbon dioxide (CO2) serves as a cheap, abundant, and renewable C1 building block for the synthesis of organic compounds and polymers. Selective and efficient CO2 fixation processes are still challenging because of the kinetic and thermodynamic stability of CO2. Among various CO2 fixation processes, the ring-opening copolymerization (ROCOP) of epoxides and CO2 gives aliphatic polycarbonates with high atom economy, although the chemical and physical properties of the resulting polycarbonates are not necessarily satisfactory. Introducing the third monomers into this ROCOP system provides new terpolymers, and the thermal, optical, mechanical or degradation properties can be added or tuned by incorporating new polymer backbones derived from the third monomers at the expense of the CO2 content. Here we review the terpolymerization reactions of epoxides, CO2, and the third monomers such as cyclic anhydrides, lactones, lactides, heteroallenes, and olefins. The development of catalysts and the control of the polymer structures are described together with the chemical and physical properties of the resulting polymers. en-copyright= kn-copyright= en-aut-name=NakaokaKoichi en-aut-sei=Nakaoka en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=357 end-page=362 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors Affecting Dynamic Postural Control Ability in Adolescent Idiopathic Scoliosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Research on postural control in patients with adolescent idiopathic scoliosis (AIS) has focused on static postural control, with few studies assessing dynamic postural control. We aimed to identify factors affecting index of postural stability (IPS), a dynamic postural control parameter, in patients with AIS. The participants comprised 50 female patients with AIS. We measured the IPS using stabilometry to evaluate dynamic postural control ability. We investigated age of the participants, major curve position (thoracic or thoracolumbar/lumbar), Cobb angle, and coronal balance. We then assessed the relationships between stabilometry parameters and other variables. IPS was analyzed with a linear regression model. Coronal balance, major curve position, and age each correlated with dynamic postural control ability. The Cobb angle showed no correlation with any of the parameters. Our results offer new insights into the assessment of postural control in patients with AIS. en-copyright= kn-copyright= en-aut-name=YamawakiRyoko en-aut-sei=Yamawaki en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaneShuhei en-aut-sei=Yamane en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University kn-affil= affil-num=5 en-affil=Ryusoh Orthopaedic Hospital kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= en-keyword=adolescent idiopathic scoliosis kn-keyword=adolescent idiopathic scoliosis en-keyword=postural control kn-keyword=postural control en-keyword=coronal balance kn-keyword=coronal balance en-keyword=index of postural stability kn-keyword=index of postural stability en-keyword=stabilometry kn-keyword=stabilometry END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=5536 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Controlling 229Th isomeric state population in a VUV transparent crystal en-subtitle= kn-subtitle= en-abstract= kn-abstract=The radioisotope thorium-229 (Th-229) is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by vacuum ultraviolet (VUV) lasers and Th-229 has been proposed as a reference transition for ultra-precise nuclear clocks. To assess the feasibility and performance of the nuclear clock concept, time-controlled excitation and depopulation of the Th-229 isomer are imperative. Here we report the population of the Th-229 isomeric state through resonant X-ray pumping and detection of the radiative decay in a VUV transparent Th-229-doped CaF2 crystal. The decay half-life is measured to 447(25) s, with a transition wavelength of 148.18(42) nm and a radiative decay fraction consistent with unity. Furthermore, we report a new "X-ray quenching" effect which allows to de-populate the isomer on demand and effectively reduce the half-life. Such controlled quenching can be used to significantly speed up the interrogation cycle in future nuclear clock schemes. en-copyright= kn-copyright= en-aut-name=HirakiTakahiro en-aut-sei=Hiraki

Peripheral blood samples were collected, and lipid levels and myeloperoxidase and paraoxonase activity were measured. The myeloperoxidase/paraoxonase ratio, which indicates dysfunctional high-density lipoprotein, was calculated. Thiol–disulfide homeostasis and ischaemia-modified albumin were measured.
We did not identify any relationship between dysfunctional high-density lipoprotein and the physical disability, cognitive decline, fatigue and sleep problems of multiple sclerosis. Thiol–disulfide homeostasis was associated with cognitive scores. The shift of the balance towards disulfide was accompanied by a decrease in cognitive scores. On the other hand, we did not detect any relationship between fatigue and sleep disorders and thiol–disulfide homeostasis. Our findings revealed a possible correlation between cognitive dysfunction and thiol–disulfide homeostasis in multiple sclerosis patients. en-copyright= kn-copyright= en-aut-name=VuralGonul en-aut-sei=Vural en-aut-mei=Gonul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DemirEsra en-aut-sei=Demir en-aut-mei=Esra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GumusyaylaSadiye en-aut-sei=Gumusyayla en-aut-mei=Sadiye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ErenFunda en-aut-sei=Eren en-aut-mei=Funda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BarakliSerdar en-aut-sei=Barakli en-aut-mei=Serdar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NeseliogluSalim en-aut-sei=Neselioglu en-aut-mei=Salim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ErelOzcan en-aut-sei=Erel en-aut-mei=Ozcan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=2 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=4 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=5 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=7 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= en-keyword=multiple sclerosis kn-keyword=multiple sclerosis en-keyword=dysfunctional HDL kn-keyword=dysfunctional HDL en-keyword=thiol–disulfide homeostasis kn-keyword=thiol–disulfide homeostasis en-keyword=cognitive decline kn-keyword=cognitive decline END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=25 article-no= start-page=12295 end-page=12303 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230620 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Li-Ion Transport and Solution Structure in Sulfolane-Based Localized High-Concentration Electrolytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Localized high-concentration electrolytes (LHCEs), which are mixtures of highly concentrated electrolytes (HCEs) and non-coordinating diluents, have attracted significant interest as promising liquid electrolytes for next-generation Li secondary batteries, owing to their various beneficial properties both in the bulk and at the electrode/electrolyte interface. We previously reported that the large Li+-ion transference number in sulfolane (SL)-based HCEs, attributed to the unique exchange/hopping-like Li+-ion conduction, decreased upon dilution with the non-coordinating hydrofluoroether (HFE) despite the retention of the local Li+-ion coordination structure. Therefore, in this study, we investigated the effects of HFE dilution on the Li+ transference number and the solution structure of SL-based LHCEs via the analysis of dynamic ion correlations and molecular dynamics simulations. The addition of HFE caused nano-segregation in the SL-based LHCEs to afford polar and nonpolar domains and fragmentation of the polar ion-conducting pathway into smaller clusters with increasing HFE content. Analysis of the dynamic ion correlations revealed that the anti-correlated Li+–Li+ motions were more pronounced upon HFE addition, suggesting that the Li+ exchange/hopping conduction is obstructed by the non-ion-conducting HFE-rich domains. Thus, the HFE addition affects the entire solution structure and ion transport without significantly affecting the local Li+-ion coordination structure. Further studies on ion transport in LHCEs would help obtain a design principle for liquid electrolytes with high ionic conductivity and large Li+-ion transference numbers. en-copyright= kn-copyright= en-aut-name=SudohTaku en-aut-sei=Sudoh en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaShuhei en-aut-sei=Ikeda en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigenobuKeisuke en-aut-sei=Shigenobu en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuzukiSeiji en-aut-sei=Tsuzuki en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DokkoKaoru en-aut-sei=Dokko en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanabeMasayoshi en-aut-sei=Watanabe en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShinodaWataru en-aut-sei=Shinoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UenoKazuhide en-aut-sei=Ueno en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Taku Sudoh Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=2 en-affil=Department of Materials Chemistry, Nagoya University kn-affil= affil-num=3 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=4 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=5 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= affil-num=6 en-affil=Advanced Chemical Energy Research Centre (ACERC), Institute of Advanced Sciences, Yokohama National University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science and Department of Chemistry, Okayama University kn-affil= affil-num=8 en-affil=Department of Chemistry and Life Science, Yokohama National University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=SJ article-no= start-page=SJ1002 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reconfigurable waveguide based on valley topological phononic crystals with local symmetry inversion via continuous translation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We proposed a reconfigurable valley topological acoustic waveguide constructed using a 2D phononic crystal (PnC) with C3v symmetric arrangement of three rods in the unit cell. An interface between two types of PnCs with differently oriented unit cells exhibits high robustness of the valley transport of acoustic waves via the topologically protected state. Structural reconfiguration was introduced by the continuous translation of rod arrays in the PnCs. The topological phase transition in this translational change was quantitatively identified by the change in the Berry curvature. The translation of the rods leaves a dimer array at the interface, creating a localized/defective mode along the waveguide. Despite the presence of the localized mode, the acoustic wave can propagate along the reconfigurable waveguide the same as the original waveguide. The continuous translation of a rod array can be used to turn on and off the bandgap. This can be a new approach to design a robust acoustic device with a high reconfigurability. en-copyright= kn-copyright= en-aut-name=AliMd. Shuzon en-aut-sei=Ali en-aut-mei=Md.

The spectrum, with a partially resolved rotational structure, was obtained by using the buffer-gas cooling technique and a single-mode tunable laser. Our new analysis reveals that the S-1 <- S-0 0(0)(0) band belongs to the a-type transition, where the electronic transition moment aligns parallel to the NH-HN direction, allowing the assignment of the S-1 state to B-1(3u). These results agree with a prior study using supersonic expansion and are well supported by theoretical calculations. Interestingly, the rotational constant B in the S-1 state, which is often smaller than that in the ground state for typical molecules, was found to be slightly larger than that in the S-0 (1)A(g) state. This suggests a change in the character of pi bonds with the electronic excitation. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaNaofumi en-aut-sei=Nakayama en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=4 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=5 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=6 en-affil=CONFLEX Corporation kn-affil= affil-num=7 en-affil=Molecular Photoscience Research Center, Kobe University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=e17013 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heterogeneity of the effect of the COVID-19 pandemic on the incidence of Metabolic Syndrome onset at a Japanese campus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. The coronavirus disease 2019 (COVID-19) outbreak began in China in December 2019, with the World Health Organization declaring a state of emergency in January 2020. Worldwide implementation of lockdown measures to slow the spread of the virus led to reduced physical activity, disrupted eating habits, mental health issues, and sleep disturbances, which increased the risk of lifestyle -related diseases such as metabolic syndrome (MetS). During the COVID-19 pandemic, healthcare workers, especially intensive care workers, experienced longer working hours and burnout, which further increased the risk of lifestyle -related diseases. Accordingly, it is important to identify individuals at a risk of new -onset MetS during a pandemic, which could direct preventive interventions. This study aimed to assess the heterogeneous impact of the COVID-19 pandemic on the incidence of new -onset MetS based on the conditional average treatment effect (CATE) and to identify at -risk populations.
Methods. This study analyzed health checkup data obtained from Okayama University Shikata Campus workers using paired baseline and follow-up years. Baseline data encompassed 2017 to 2019, with respective follow-up data from 2018 to 2020. Furthermore, as the COVID-19 pandemic in Japan began in January 2020, workers who underwent follow-up health checkups in 2018 to 2019 and 2020 were considered as "unexposed"and "exposed,"respectively. As the Shikata campus has several departments, comparisons among departments were made. The primary outcome was new -onset MetS at follow-up. Predictor variables included baseline health checkup results, sex, age, and department (administrative, research, medical, or intensive care department). X -learner was used to calculate the CATE.
Results. This study included 3,572 eligible individuals (unexposed, n = 2,181; exposed, n = 1,391). Among them, 1,544 (70.8%) and 866 (62.3%) participants in the unexposed and exposed groups, respectively, were females. The mean age (+/- standard deviation) of the unexposed and exposed groups was 48.2 +/- 8.2 and 47.8 +/- 8.3 years, respectively. The COVID-19 pandemic increased the average probability of new -onset MetS by 4.4% in the overall population. According to the department, the intensive care department showed the highest CATE, with a 15.4% increase. Moreover, there was large heterogeneity according to the department. The high-CATE group was characterized by older age, urinary protein, elevated liver enzymes, higher triglyceride levels, and a history of hyperlipidemia treatment.
Conclusions. This study demonstrated that the COVID-19 pandemic increased the incidence of new -onset MetS, with this effect showing heterogeneity at a single Japanese campus. Regarding specific populations, workers in the intensive care department showed an increased risk of new -onset MetS. At -risk populations require specific preventive interventions in case the current COVID-19 pandemic persists or a new pandemic occurs. en-copyright= kn-copyright= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Metabolic syndrome kn-keyword=Metabolic syndrome en-keyword=Healch check up kn-keyword=Healch check up en-keyword=Conditional average treatment effect kn-keyword=Conditional average treatment effect en-keyword=CATE kn-keyword=CATE en-keyword=Public health kn-keyword=Public health en-keyword=Pandemic kn-keyword=Pandemic END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=171 end-page=184 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Relationships among Internalized Stigma, Sense of Coherence, and Personal Recovery of Persons with Schizophrenia Living in the Community en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated (i) the relationships among internalized stigma (IS), sense of coherence (SOC), and the personal recovery (PR) of persons with schizophrenia living in the community, and (ii) how to improve the support for these individuals. A questionnaire survey on IS, SOC, and PR was sent by mail to 270 persons with schizophrenia living in the community who were using psychiatric daycare services, of whom 149 responded and 140 were included in the analysis. We established a hypothetical model in which IS influences PR, and SOC influences IS and PR, and we used structural equation modeling to examine the relationships among these concepts. The goodness of fit was acceptable. Our findings suggest that rather than directly promoting PR, SOC promotes PR by mitigating the impact of IS. It is important for nurses/supporters to support individuals with schizophrenia living in the community so that they have opportunities to reflect on their own experiences through their activities and to share their experiences with peers. Nurses/supporters themselves should also reflect on their own support needs. Our findings suggest that this will lead to a reduction of IS and the improvement of SOC, which will in turn promote personal recovery. en-copyright= kn-copyright= en-aut-name=KuramotoAya en-aut-sei=Kuramoto en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeKumi en-aut-sei=Watanabe en-aut-mei=Kumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=School of Nursing, Faculty of Medicine, Kagawa University kn-affil= en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=internalized stigma kn-keyword=internalized stigma en-keyword=sense of coherence kn-keyword=sense of coherence en-keyword=personal recovery kn-keyword=personal recovery en-keyword=community kn-keyword=community END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=163 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual’s daily life. We investigated the prediction of patients’ post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter’s association with functional outcomes is well established. We examined patients’ responses to a light touch (LT) and pin prick (PP) at admission and the response data’s usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (β=0.07 (0.01), p<0.001) and the PP response (β=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients’ functional outcomes after an SCI, although the magnitude of their contributions is not high. en-copyright= kn-copyright= en-aut-name=DeguchiTakayuki en-aut-sei=Deguchi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Nlandu Roger Ngatu en-aut-sei=Nlandu Roger Ngatu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Kibikogen Rehabilitation Center for Employment Injuries kn-affil= affil-num=4 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=functional independence measure kn-keyword=functional independence measure en-keyword=light touch kn-keyword=light touch en-keyword=pin prick kn-keyword=pin prick en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=Japanese National Spinal Cord Injury Database kn-keyword=Japanese National Spinal Cord Injury Database END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=135 end-page=142 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photon-Counting Detector CT: Potential for 75% Reduction in Contrast Medium Amount: A Phantom Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the potential reduction in contrast medium utilization using photon-counting detector computed tomography (PCD-CT). One PCD-CT scan (CT1) and three conventional (non-PCD-CT) CT scans (CT2-CT4) were performed using a multi-energy CT phantom that contained eight rods with different iodine concentrations (0.2, 0.5, 1, 2, 5, 10, 15, and 20 mg/ml). The CT values of the seven groups (CT1 for 40, 50, 60, and 70 keV; and CT2-4) were measured. Noise and contrast-to-noise ratio (CNR) were assessed for the eight rods at various iodine concentrations. CT2 and CT1 (40 keV) respectively required 20 mg/ml and 5 mg/ml of iodine, indicating that a comparable contrast effect could be obtained with approximately one-fourth of the contrast medium amount. The standard deviation values increased at lower energy levels irrespective of the iodine concentration. The CNR exhibited a decreasing trend with lower iodine concentrations, while it remained relatively stable across all iodine levels (40-70 keV). This study demonstrated that virtual monochromatic 40 keV images offer a similar contrast effect with a reduced contrast medium amount when compared to conventional CT systems at 120 kV. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoHayato en-aut-sei=Saito en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiHaruhiko en-aut-sei=Takaki en-aut-mei=Haruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagoshiAyako en-aut-sei=Nakagoshi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaMaki en-aut-sei=Wada en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photon-counting detector CT kn-keyword=photon-counting detector CT en-keyword=energy integrating detector CT kn-keyword=energy integrating detector CT en-keyword=computed tomography kn-keyword=computed tomography en-keyword=contrast medium amount kn-keyword=contrast medium amount en-keyword=reduction kn-keyword=reduction END start-ver=1.4 cd-journal=joma no-vol=965 cd-vols= no-issue=1 article-no= start-page=91 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors en-subtitle= kn-subtitle= en-abstract= kn-abstract=If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations. In addition, there is anticipation that observation of the diffuse supernova neutrino background will yield discoveries in the near future, given that experimental upper limits are approaching theoretical predictions. We have developed a new supernova event simulator for water Cherenkov neutrino detectors, such as the highly sensitive Super-Kamiokande. This simulator calculates the neutrino interaction in water for two simulation purposes, individual core-collapse supernova bursts and diffuse supernova neutrino background. Based on this simulator, we can evaluate the precision in determining the location of supernovae and estimate the expected number of events related to the diffuse supernova neutrino background in Super-Kamiokande. In this paper, we describe the basic structure of the simulator and its demonstration. en-copyright= kn-copyright= en-aut-name=NakanishiFumi en-aut-sei=Nakanishi en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IzumiyamaShota en-aut-sei=Izumiyama en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaMasayuki en-aut-sei=Harada en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Tokyo Institute of Technology kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=191 end-page=205 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Proposal for Creativity-oriented Inquiry-based Classes for Liberal Arts Education in Universities Analysis of Practical Results of the Liberal Arts Education Class “Creativity in Life” at Okayama University II kn-title=大学教養教育に適した創造性を重視した探究型授業の提案　岡山大学教養教育科目「生活の中の創造性」の実践結果の分析Ⅱ en-subtitle= kn-subtitle= en-abstract=　In anticipation of the academic year 2025, when high school students who have experienced inquiry-based learning under the new Courses of Study will be university students, we have developed a new class that combines knowledge of physics and clothing science on the subject of "color" and incorporates project-based activities as a university liberal arts education course. As in the previous year, the class encourages students to take initiative and stimulates creative thinking by incorporating devices that encourage them to perceive things with an awareness of various connections and to become aware of the characteristics of their own thinking and senses. As a result of the analysis of the students' descriptions on the shuttle cards, the webbing created in the process of discussion, and the CLASS survey paper that measures students' thoughts and attitudes toward physics and physics learning, it became clear that the class was highly effective in encouraging students to "become aware of their own existence to think, feel, and judge independently and interactively. This is an essential element in the cultivation of creativity, which is important as a foundation for inquiry-based learning. kn-abstract=新学習指導要領で探究的な学びを経験した高校生が大学で学び始める2025年度を控え，大学の教養教育科目として，「色」を主題にして物理学と被服学の知見を組み合わせ，プロジェクト型の活動も組み入れた新たな授業を開発し実践した。昨年度の実践と同様に，様々なつながりを意識してものごとを捉えたり，学生自身の思考や感覚の特徴を自覚させることを促す仕掛けを組み込むことで，学生の主体性を促して創造的な思考を刺激する授業になっている。受講生のシャトルカードの記述，考察過程で作成したウェビング，物理や物理学習に対する学生の思考や態度を測定するCLASS調査紙などの分析の結果，「主体的，対話的に考え，感じ，判断する自分自身の存在を意識すること」を促す効果が大きいことが明らかになった。これは，探究的な学びの土台として重要な創造性の涵養に欠かせない要素になる。 en-copyright= kn-copyright= en-aut-name=INADAYoshihiko en-aut-sei=INADA en-aut-mei=Yoshihiko kn-aut-name=稲田佳彦 kn-aut-sei=稲田 kn-aut-mei=佳彦 aut-affil-num=1 ORCID= en-aut-name=SHINOHARAYoko en-aut-sei=SHINOHARA en-aut-mei=Yoko kn-aut-name=篠原陽子 kn-aut-sei=篠原 kn-aut-mei=陽子 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=探究型授業 kn-keyword=探究型授業 en-keyword=創造性 kn-keyword=創造性 en-keyword=物理学 kn-keyword=物理学 en-keyword=被服学 kn-keyword=被服学 en-keyword=ウェビング kn-keyword=ウェビング en-keyword=creativity kn-keyword=creativity en-keyword=physics kn-keyword=physics en-keyword=clothing science kn-keyword=clothing science END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=635 end-page=645 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Nutritional Support Combined with Neuromuscular Electrical Stimulation on Muscle Strength and Thickness: A Randomized Controlled Trial in Healthy Young Adult Males en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the management of post-injury patients with activity limitations, methods to prevent musculoskeletal disorders and hasten recovery are important. This randomized controlled, single-blinded study was a preliminary investigation of the combined effect of nutritional support with neuromuscular electrical stimulation (NMES) on muscle strength and thickness. Healthy young adult males (median age, 21 years) were enrolled; each of their hands was randomly assigned to one of the following four groups: Placebo, Nutrition, NMES, and Nutrition + NMES. All participants received whey protein or placebo (3x/week for 6 weeks) and NMES training (3x/week for 6 weeks) on the abductor digiti minimi (ADM) muscle of either the left or right hand. ADM muscle strength and thickness were analyzed at baseline and at week 7. We analyzed 38 hands (9 Placebo, 10 Nutrition, 9 NMES, 10 Nutrition + NMES). There was significantly greater muscle strengthening in the Nutrition + NMES group compared to the Placebo group or the NMES group, but no significant difference in gain of muscle thickness. The combined intervention may be effective in improving muscle strength. Future clinical trials targeting various muscles after sports-related injuries are warranted. en-copyright= kn-copyright= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamuraKazunori en-aut-sei=Okamura en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaMasaki en-aut-sei=Hasegawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanaiShusaku en-aut-sei=Kanai en-aut-mei=Shusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=4 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=5 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= en-keyword=whey protein kn-keyword=whey protein en-keyword=electrical stimulation kn-keyword=electrical stimulation en-keyword=muscle strength kn-keyword=muscle strength en-keyword=healthy volunteers kn-keyword=healthy volunteers END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=511 end-page=516 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Associations among Preoperative Malnutrition, Muscle Loss, and Postoperative Walking Ability in Intertrochanteric Fractures: A Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sarcopenia and malnutrition are increasing in older adults and are reported risk factors for functional impairment after hip fracture surgery. This study aimed to investigate the associations between skeletal muscle mass loss, malnutrition, and postoperative walking ability in patients with hip fracture. We retrospectively reviewed patients who underwent intertrochanteric fracture surgery at our institute. The psoas muscle index, controlling nutritional status score, and functional ambulation category (FAC) were used to evaluate skeletal muscle mass, nutritional status, and walking ability, respectively. Six months after surgery, walking ability was assessed as either “gait disturbance” or “independent gait”. Multivariate binomial logistic regression analysis, with skeletal muscle mass, nutritional status, and other factors, was used to predict the risk of being assigned to the gait disturbance group. This study included 95 patients (mean age, 85.2 years; 70 women). Sixty-six patients had low skeletal muscle mass, 35 suffered from malnutrition, and 28 had both. Malnutrition and low skeletal muscle mass were significantly associated with postoperative gait disturbance (FAC < 3). Preoperative low skeletal muscle mass and malnutrition were risk factors for postoperative poor walking ability. Further preventive interventions focusing on skeletal muscle mass and nutritional status are required. en-copyright= kn-copyright= en-aut-name=SatoKohei en-aut-sei=Sato en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiHironori en-aut-sei=Tsuji en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorimitsuMasanori en-aut-sei=Yorimitsu en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UeharaTakenori en-aut-sei=Uehara en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaoShinichiro en-aut-sei=Takao en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HataToshiaki en-aut-sei=Hata en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukuokaShiro en-aut-sei=Fukuoka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Kawasaki Medical School, General Medical Center kn-affil= affil-num=10 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=nutrition kn-keyword=nutrition en-keyword=geriatric hip fracture kn-keyword=geriatric hip fracture en-keyword=psoas muscle index kn-keyword=psoas muscle index en-keyword=controlling nutritional status score kn-keyword=controlling nutritional status score END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=443 end-page=449 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does Participation in the Setouchi Triennale Foster Social Capital? : A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined whether participation in an art project was associated with higher social capital (SC). We conducted a questionnaire survey from November 2021 to March 2022 among residents aged 20 years or older of Naoshima, an island in Kagawa Prefecture, Japan. Before the survey, the Setouchi Triennale had been held on Naoshima four times, starting in 2010. We calculated propensity scores for Triennale participation and performed propensity score matching. We then compared cognitive and structural SC by Triennale participation and found significant differences, respectively. We adopted a conditional ordered logistic regression analysis with propensity score matching for cognitive or structural SC, and found adjusted odd ratios of 2.913 (95%CI, 1.846-4.596) for cognitive SC and 4.535 (95%CI, 2.839-7.244) for structural SC. Our findings suggest that Triennale participation enhanced the cognitive aspect of SC while also building structural SC. en-copyright= kn-copyright= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AooKen en-aut-sei=Aoo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishitaYosuke en-aut-sei=Nishita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsuriMasao en-aut-sei=Tsuri en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Economics, Musashi University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=social capital kn-keyword=social capital en-keyword=art project kn-keyword=art project en-keyword=propensity score matching kn-keyword=propensity score matching END start-ver=1.4 cd-journal=joma no-vol=951 cd-vols= no-issue=2 article-no= start-page=L27 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Search for Astrophysical Electron Antineutrinos in Super-Kamiokande with 0.01% Gadolinium-loaded Water en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the first search result for the flux of astrophysical electron antineutrinos for energies O(10) MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In 2020 June, gadolinium was introduced to the ultrapure water of the SK detector in order to detect neutrons more efficiently. In this new experimental phase, SK-Gd, we can search for electron antineutrinos via inverse beta decay with efficient background rejection thanks to the high efficiency of the neutron tagging technique. In this paper, we report the result for the initial stage of SK-Gd, during 2020 August 26, and 2022 June 1 with a 22.5 x 552 kton center dot day exposure at 0.01% Gd mass concentration. No significant excess over the expected background in the observed events is found for the neutrino energies below 31.3 MeV. Thus, the flux upper limits are placed at the 90% confidence level. The limits and sensitivities are already comparable with the previous SK result with pure water (22.5 x 2970 kton center dot day) owing to the enhanced neutron tagging. Operation with Gd increased to 0.03% started in 2022 June. en-copyright= kn-copyright= en-aut-name=HaradaM. en-aut-sei=Harada en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=387 end-page=394 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=No epidemiological studies have examined the health effects of daily bathing in radon hot springs.

We collected information about the participants’ bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoYuki en-aut-sei=Fujimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YukimineRyohei en-aut-sei=Yukimine en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Longevity and Social Medicine (Geriatrics), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=radon hot spring kn-keyword=radon hot spring en-keyword=bathing habit kn-keyword=bathing habit en-keyword=self-rated health kn-keyword=self-rated health en-keyword=cross-section study kn-keyword=cross-section study END start-ver=1.4 cd-journal=joma no-vol=2023 cd-vols= no-issue=6 article-no= start-page=063H01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Angular correlation of the two gamma rays produced in the thermal neutron capture on gadolinium-155 and gadolinium-157 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ANNRI-Gd collaboration studied in detail the single gamma-ray spectrum produced from the thermal neutron capture on Gd-155 and Gd-157 in our previous publications. Gadolinium targets were exposed to a neutron beam provided by the Japan Spallation Neutron Source (JSNS) in J-PARC, Japan. In the present analysis, one new additional coaxial germanium crystal was used in combination with the 14 germanium crystals in the cluster detectors to study the angular correlation of the two gamma rays emitted in the same neutron capture. We present for the first time angular correlation functions for two gamma rays produced during the electromagnetic cascade transitions in the (n, gamma) reactions on Gd-155 and Gd-157. As expected, we observe mild angular correlations for the strong, but rare transitions from the resonance state to the two energy levels of known spin-parities. Contrariwise, we observe negligibly small angular correlations for arbitrary pairs of two gamma rays produced in the majority of cascade transitions from the resonance state to the dense continuum states. en-copyright= kn-copyright= en-aut-name=GouxPierre en-aut-sei=Goux en-aut-mei=Pierre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GlessgenFranz en-aut-sei=Glessgen en-aut-mei=Franz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GazzolaEnrico en-aut-sei=Gazzola en-aut-mei=Enrico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ReenMandeep Singh en-aut-sei=Reen en-aut-mei=Mandeep Singh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FocillonWilliam en-aut-sei=Focillon en-aut-mei=William kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GoninMichel en-aut-sei=Gonin en-aut-mei=Michel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaTomoyuki en-aut-sei=Tanaka en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HagiwaraKaito en-aut-sei=Hagiwara en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AliAjmi en-aut-sei=Ali en-aut-mei=Ajmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SudoTakashi en-aut-sei=Sudo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakudaMakoto en-aut-sei=Sakuda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=CollazuolGianmaria en-aut-sei=Collazuol en-aut-mei=Gianmaria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KimuraAtsushi en-aut-sei=Kimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NakamuraShoji en-aut-sei=Nakamura en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=IwamotoNobuyuki en-aut-sei=Iwamoto en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=WurmMichael en-aut-sei=Wurm en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=Département de Physique, École Polytechnique, IN2P3/CNRS kn-affil= affil-num=6 en-affil=Département de Physique, École Polytechnique, IN2P3/CNRS kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Department of Physics, Okayama University kn-affil= affil-num=9 en-affil=Department of Physics, Okayama University kn-affil= affil-num=10 en-affil=Department of Physics, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=Department of Physics, Okayama University kn-affil= affil-num=13 en-affil=INFN Sezione di Padova and Università di Padova, Dipartimento di Fisica kn-affil= affil-num=14 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=15 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=16 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=17 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=18 en-affil=Institut für Physik, Johannes Gutenberg-Universität Mainz kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=273 end-page=280 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of Simple Diffusion Kurtosis Imaging for Head and Neck Tumors: An Early Clinical Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffusion kurtosis (DK) imaging (DKI), a type of restricted diffusion-weighted imaging, has been reported to be useful for tumor diagnoses in clinical studies. We developed a software program to simultaneously create DK images with apparent diffusion coefficient (ADC) maps and conducted an initial clinical study. Multi-shot echo-planar diffusion-weighted images were obtained at b-values of 0, 400, and 800 sec/mm2 for simple DKI, and DK images were created simultaneously with the ADC map. The usefulness of the DK image and ADC map was evaluated using a pixel analysis of all pixels and a median analysis of the pixels of each case. Tumor and normal tissues differed significantly in both pixel and median analyses. In the pixel analysis, the area under the curve was 0.64 for the mean kurtosis (MK) value and 0.77 for the ADC value. In the median analysis, the MK value was 0.74, and the ADC value was 0.75. The MK and ADC values correlated moderately in the pixel analysis and strongly in the median analysis. Our simple DKI system created DK images simultaneously with ADC maps, and the obtained MK and ADC values were useful for differentiating head and neck tumors from normal tissue. en-copyright=

We have developed and implemented a new class on the topic of ‘color’ as a liberal arts education course at a university, combining knowledge of physics and clothing science and incorporating project-based activities. By incorporating mechanisms that encourage students to perceive things with an awareness of various connections and to become aware of the characteristics of their own thinking and senses, the class stimulates students for proactive and creativity. Analysis of the shuttle card, webbing in the discussion process, and the CLASS which measures students' thinking and attitudes toward physics and physical learning, revealed that the program was highly effective in promoting ‘awareness of one's own existence to think, feel, and judge’ which is essential to cultivate creativity. kn-abstract=近年，創造性の涵養を重視する教育が国内外で盛んになり，総合的な探究の時間やSTEAM 教育など，教科横断的に創造性を刺激する授業の開発も進んでいる。我々は，大学の教養教 育科目として，「色」を主題にして物理学と被服学の知見を組み合わせ，プロジェクト型の 活動も組み入れた新たな授業を開発し実践した。様々なつながりを意識してものごとを捉 えたり，学生自身の思考や感覚の特徴を自覚させることを促す仕掛けを組み込むことで， 学生の主体性を促して創造的な思考を刺激する授業になっている。受講生のシャトルカー ドの記述，考察過程で作成したウェビング，物理や物理学習に対する学生の思考や態度を 測定するCLASS 調査紙などの分析の結果，創造性の涵養に欠かせない，「考え，感じ，判断 する自分自身の存在を意識すること」を促す効果が大きいことが明らかになった。 en-copyright= kn-copyright= en-aut-name=InadaYoshihiko en-aut-sei=Inada en-aut-mei=Yoshihiko kn-aut-name=稲田佳彦 kn-aut-sei=稲田 kn-aut-mei=佳彦 aut-affil-num=1 ORCID= en-aut-name=ShinoharaYoko en-aut-sei=Shinohara en-aut-mei=Yoko kn-aut-name=篠原陽子 kn-aut-sei=篠原 kn-aut-mei=陽子 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=創造性 (creativity) kn-keyword=創造性 (creativity) en-keyword=物理学 (physics) kn-keyword=物理学 (physics) en-keyword=被服学 (clothing science) kn-keyword=被服学 (clothing science) en-keyword=STEAM 教育 (STEAM education) kn-keyword=STEAM 教育 (STEAM education) en-keyword=ICT kn-keyword=ICT END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=389 end-page=403 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Children’ s Books as Teaching Material that Help Preschoolers Gain Understanding of Physical Disabilities kn-title=幼児の身体障害への理解を援助する絵本教材 en-subtitle= kn-subtitle= en-abstract=Focusing on children’ s books about physical disabilities, this study involved the creation of a list of children’s books following the collection and analysis of children’ s books that help preschoolers gain understanding of disabilities. At the same time, the learning elements of those books and the points to note for preschool teachers were discussed. As a result, it was found that there is a wide range of children’s books about physical disabilities depending on the ideas and intentions of the writers; e.g., those that aim to promote emotional understanding, those that focus on gaining knowledge of items that assist the life of children/people with disabilities such as guide dogs and wheelchairs, and those that include both of these themes. In order to effectively utilize such children’ s books, preschool teachers must grasp the learning elements of the books, choose the appropriate book according to the target of their disability awareness education, and present the book’s content in ways that will enable the preschoolers to generalize the learnings to their everyday life. In the future, this study will be further developed by collecting cases of disability awareness education using children’ s books based on our list and analyzing their educational effects. In addition, any new children’ s book about disability awareness will be scrutinized and the list will be updated whenever necessary to enhance its practicality. kn-abstract=　本論は，身体障害を扱う絵本に焦点を当て，幼児期における障害理解を援助する絵本を収集及び分析し，絵本リストを作成すると同時に，それらの絵本の学びの要素や保育者の留意事項等について考察するものである。その結果，身体障害に関する絵本は，情緒的な理解の促進を目指したもの，盲導犬や車椅子等の障害児・者の生活を補助するものに関する知識の習得に重点が置かれたもの，その両方等，作者の思想や意図によって多種多様なものが存在することが分かった。それらを有効に活用するために保育者は，絵本に込められた学びの要素を読み取り，障害理解教育のねらいに合わせて適切な絵本を選択し，幼児の日常生活に般化されるように提示することが求められる。今後の課題は，リストを基にした現場実践から事例を収集し教育効果を分析すること，障害理解絵本が新たに出版される場合はその内容を吟味し，リストを随時更新して一層の実用化を図ること，が挙げられた。 en-copyright= kn-copyright= en-aut-name=AsanoYasumasa en-aut-sei=Asano en-aut-mei=Yasumasa kn-aut-name=浅野泰昌 kn-aut-sei=浅野 kn-aut-mei=泰昌 aut-affil-num=1 ORCID= en-aut-name=Yamaguchi (Nishioka)Yuki en-aut-sei=Yamaguchi (Nishioka) en-aut-mei=Yuki kn-aut-name=山口（西岡） 由稀 kn-aut-sei=山口（西岡） kn-aut-mei=由稀 aut-affil-num=2 ORCID= en-aut-name=BabaNoriko en-aut-sei=Baba en-aut-mei=Noriko kn-aut-name=馬場訓子 kn-aut-sei=馬場 kn-aut-mei=訓子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=倉敷市立短期大学 affil-num=2 en-affil= kn-affil=御南認定こども園 affil-num=3 en-affil= kn-affil=岡山大学学術研究院教育学域 en-keyword=幼児期 (Preschool period) kn-keyword=幼児期 (Preschool period) en-keyword=障害理解教育 (Disability awareness education) kn-keyword=障害理解教育 (Disability awareness education) en-keyword=身体障害 (Physical disabilities) kn-keyword=身体障害 (Physical disabilities) en-keyword=絵本 (Children’ s books) kn-keyword=絵本 (Children’ s books) en-keyword=保育者 (Preschool teacher) kn-keyword=保育者 (Preschool teacher) END start-ver=1.4 cd-journal=joma no-vol=2023 cd-vols= no-issue=1 article-no= start-page=013D02 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detection of the 4.4-MeV gamma rays from 16O(ν, ν′)16O(12.97 MeV, 2−) with a water Cherenkov detector in supernova neutrino bursts en-subtitle= kn-subtitle= en-abstract= kn-abstract=We first discuss and determine the isospin mixing of the two 2− states (12.53 MeV and 12.97 MeV) of the16O nucleus using inelastic electron scattering data.

The detection of γ rays for Eγ > 5 MeV from the NC reaction 16O(ν, ν′)16O(Ex > 16 MeV, T = 1) with a water Cherenkov detector in supernova neutrino bursts has been proposed and discussed by several authors previously. In this article, we discuss a new NC reaction channel from 16O(12.97 MeV, 2−) producing a 4.4-MeV γ ray, the cross section of which is more robust and even larger at low energy (Eν < 25 MeV) than the NC cross section from 16O(Ex > 16 MeV, T = 1). We also evaluate the number of such events induced by neutrinos from supernova explosion which can be observed by the Super-Kamiokande, an Earth-based 32-kton water Cherenkov detector. en-copyright= kn-copyright= en-aut-name=SakudaMakoto en-aut-sei=Sakuda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiToshio en-aut-sei=Suzuki en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ReenMandeep Singh en-aut-sei=Reen en-aut-mei=Mandeep Singh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakazatoKen'Ichiro en-aut-sei=Nakazato en-aut-mei=Ken'Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiHideyuki en-aut-sei=Suzuki en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Physics Department, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, College of Humanities and Sciences, Nihon University kn-affil= affil-num=3 en-affil=Department of Physics, Akal University kn-affil= affil-num=4 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= affil-num=5 en-affil=Department of Physics, Faculty of Science and Technology, Tokyo University of Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=53 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reliability of the Garden Alignment Index and Valgus Tilt Measurement for Nondisplaced Femoral Neck Fractures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anteroposterior (AP) alignment assessment for nondisplaced femoral neck fractures is important for determining the treatment strategy and predicting postoperative outcomes. AP alignment is generally measured using the Garden alignment index (GAI). However, its reliability remains unknown. We compared the reliability of GAI and a new AP alignment measurement (valgus tilt measurement [VTM]) using preoperative AP radiographs of nondisplaced femoral neck fractures. The study was designed as an intra- and inter-rater reliability analysis. The raters were four trauma surgeons who assessed 50 images twice. The main outcome was the intraclass correlation coefficient (ICC). To calculate intra- and inter-rater reliability, we used a mixed-effects model considering rater, patient, and time. The overall ICC (95% CI) of GAI and VTM for intra-rater reliability was 0.92 (0.89-0.94) and 0.86 (0.82-0.89), respectively. The overall ICC of GAI and VTM for inter-rater reliability was 0.92 (0.89-0.95), and 0.85 (0.81-0.88), respectively. The intra- and inter-rater reliability of GAI was higher in patients aged <80 years than in patients aged >= 80 years. Our results showed that GAI is a more reliable measurement method than VTM, although both are reliable. Variations in patient age should be considered in GAI measurements. en-copyright= kn-copyright= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaYosuke en-aut-sei=Tomita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiroshitaAkihiro en-aut-sei=Shiroshita en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoToshiyuki en-aut-sei=Matsumoto en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health Care, Takasaki University of Health and Welfare kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Scientific Research Works Peer Support Group (SRWS-PSG) kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= en-keyword=femoral neck fracture kn-keyword=femoral neck fracture en-keyword=intracapsular hip fracture kn-keyword=intracapsular hip fracture en-keyword=Garden alignment index kn-keyword=Garden alignment index en-keyword=posterior tilt kn-keyword=posterior tilt en-keyword=inter-rater reliability kn-keyword=inter-rater reliability en-keyword=intra-rater reliability kn-keyword=intra-rater reliability en-keyword=intraclass correlation coefficients kn-keyword=intraclass correlation coefficients END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue= article-no= start-page=e13817 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Validation of pencil beam scanning proton therapy with multi-leaf collimator calculated by a commercial Monte Carlo dose engine en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the clinical beam commissioning results and lateral penumbra characteristics of our new pencil beam scanning (PBS) proton therapy using a multi-leaf collimator (MLC) calculated by use of a commercial Monte Carlo dose engine. Eighteen collimated uniform dose plans for cubic targets were optimized by the RayStation 9A treatment planning system (TPS), varying scan area, modulation widths, measurement depths, and collimator angles. To test the patient-specific measurements, we also created and verified five clinically realistic PBS plans with the MLC, such as the liver, prostate, base-of-skull, C-shape, and head-and-neck. The verification measurements consist of the depth dose (DD), lateral profile (LP), and absolute dose (AD). We compared the LPs and ADs between the calculation and measurements. For the cubic plans, the gamma index pass rates (gamma-passing) were on average 96.5% +/- 4.0% at 3%/3 mm for the DD and 95.2% +/- 7.6% at 2%/2 mm for the LP. In several LP measurements less than 75 mm depths, the gamma-passing deteriorated (increased the measured doses) by less than 90% with the scattering such as the MLC edge and range shifter. The deteriorated gamma-passing was satisfied by more than 90% at 2%/2 mm using uncollimated beams instead of collimated beams except for three planes. The AD differences and the lateral penumbra width (80%-20% distance) were within +/- 1.9% and +/- 1.1 mm, respectively. For the clinical plan measurements, the gamma-passing of LP at 2%/2 mm and the AD differences were 97.7% +/- 4.2% on average and within +/- 1.8%, respectively. The measurements were in good agreement with the calculations of both the cubic and clinical plans inserted in the MLC except for LPs less than 75 mm regions of some cubic and clinical plans. The calculation errors in collimated beams can be mitigated by substituting uncollimated beams. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuraiYusuke en-aut-sei=Sakurai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyataJunya en-aut-sei=Miyata en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaradaShuichi en-aut-sei=Harada en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiotherapy, Medical Co.

Recent time-resolved serial femtosecond crystallography identified large reorganization of the primary coordination sphere in the S-2 to S-3 transition, which elicits a cascade of events involving Mn oxidation and water molecule binding to a putative catalytic Mn site. We examined how the crystallographic fields, created by transient conformational states of the OEC at various time points, affect the thermodynamics of various isomers of the Mn cluster using DFT calculations, with an aim of comprehending the functional roles of the flexible primary coordination sphere in the S-2 to S-3 transition and in the recovery of the S-2 state. The results show that the relative movements of surrounding residues change the size and shape of the cavity of the cluster and thereby affect the thermodynamics of various catalytic intermediates as well as the ability to capture a new water molecule at a coordinatively unsaturated site. The implication of these findings is that the protein dynamics may serve to gate the catalytic reaction efficiently by controlling the sequence of Mn oxidation/reduction and water binding/release. This interpretation is consistent with EPR experiments; g similar to 5 and g similar to 3 signals obtained after near-infrared (NIR) excitation of the S-3 state at 4 K and a g similar to 5 only signal produced after prolonged incubation of the S-3 state at 77 K can be best explained as originating from water-bound S-2 clusters (S-total = 7/2) under a S-3 ligand field, i.e., the immediate one-electron reduction products of the oxyl-oxo (S-total = 6) and hydroxo-oxo (S-total = 3) species in the S-3 state. en-copyright= kn-copyright= en-aut-name=IsobeHiroshi en-aut-sei=Isobe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShojiMitsuo en-aut-sei=Shoji en-aut-mei=Mitsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiTakayoshi en-aut-sei=Suzuki en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiKizashi en-aut-sei=Yamaguchi en-aut-mei=Kizashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Center for Computational Science, University of Tsukuba, kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for NanoScience Design, Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=731 end-page=736 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Case of Idiopathic Spinal Cord Herniation Treated by DuraGen® Collagen Matrix Graft en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of idiopathic spinal cord herniation (ISCH) with a history of cerebrospinal fluid (CSF) leakage. ISCH is a protrusion of the spinal cord through a dural defect. Thin constructive interference in steady-state (CISS) images clearly demonstrated the herniated cord in the present case. The myelopathy worsened and the patient underwent surgery for reduction of herniated spinal cord; the dural defect was filled by placing collagen matrix graft (DuraGen®) between the inner and outer dural layers. The patient’s symptoms have improved without relapse for 8 months since surgery. This method may be a good surgical option for cases of spinal cord herniation. en-copyright= kn-copyright= en-aut-name=KamamuraMaho en-aut-sei=Kamamura en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsushitaToshi en-aut-sei=Matsushita en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cerebrospinal fluid leakage kn-keyword=cerebrospinal fluid leakage en-keyword=constructive interference in steady state kn-keyword=constructive interference in steady state en-keyword=collagen matrix graft kn-keyword=collagen matrix graft en-keyword=magnetic resonance image kn-keyword=magnetic resonance image en-keyword=spinal cord herniation kn-keyword=spinal cord herniation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=715 end-page=721 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Graphene Oxide-based Endodontic Sealer: An in Vitro Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The failure of endodontic treatment is directly associated with microbial infection in the root canal or periapical areas. An endodontic sealer that is both bactericidal and biocompatible is essential for the success of root canal treatments. This is one of the vital issues yet to be solved in clinical dental practice. This in vitro study assessed the effectiveness of graphene oxide (GO) composites GO-CaF2 and GO-Ag-CaF2 as endodontic sealer materials. Dentin slices were coated with either the GO-based composites or commonly used root canal sealers (non-eugenol zinc oxide sealer). The coated slices were treated in 0.9% NaCl, phosphate-buffered saline (PBS), and simulated body fluid (SBF) at 37˚C for 24 hours to compare their sealing effect on the dentin surface. In addition, the radiopacity of these composites was examined to assess whether they complied with the requirements of a sealer for good radiographic visualization. Scanning electron microscopy showed the significant sealing capability of the composites as coating materials. Radiographic images confirmed their radiopacity. Mineral deposition indicated their bioactivity, especially of GO-Ag-CaF2, and thus it is potential for regenerative application. They were both previously shown to be bactericidal to oral microbes and cytocompatible with host cells. With such a unique assemblage of critical properties, these GO-based composites show promise as endodontic sealers for protection against reinfection in root canal treatment and enhanced success in endodontic treatment overall. en-copyright= kn-copyright= en-aut-name=Mohammed Zahedul Islam Nizami en-aut-sei=Mohammed Zahedul Islam Nizami en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GorduysusMelahat en-aut-sei=Gorduysus en-aut-mei=Melahat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AriasZulema en-aut-sei=Arias en-aut-mei=Zulema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=6 en-affil=Research Core for Interdisciplinary Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=bioactive sealer kn-keyword=bioactive sealer en-keyword=graphene oxide kn-keyword=graphene oxide en-keyword=mineral deposition kn-keyword=mineral deposition en-keyword=antimicrobial activity kn-keyword=antimicrobial activity en-keyword=radiopacity kn-keyword=radiopacity END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=吉井川及び旭川の汽水域における干潟造成に向けた物理環境特性の検討 kn-title=Investigation of the physical environmental characteristics for tidal flat creation in brackish water areas of the Yoshii river and the Asahi river en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AL-BAGHDADI Mohammed Baqer Naji en-aut-sei=AL-BAGHDADI Mohammed Baqer Naji en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=597 end-page=603 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genital Feminizing Surgery without Vaginoplasty as a Safe, Aesthetic, and Cost-Effective Option for Gender-Affirming Surgery for Transwomen en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gender affirming surgery (GAS) has important impacts for people with gender incongruence (GI), both physically and socially. As the societal acceptance of gender diversity spreads, the number of individuals with GI who wish to be identified as the gender of their choice is increasing. Indeed, many elderly people who have lived a long time with GI now wish to undergo GAS, but face greater surgical risks due to greater burdens of underlying medical conditions. Generally, vaginoplasty is performed for transwomen; however, this surgery is time-consuming and involves heavy bleeding, and thus, should be avoided in elderly people. A less invasive technique is needed. In this article, we describe a new, less invasive genital feminizing surgical technique for transwomen with reports from two clinical cases. We present this novel technique as a safe, aesthetic, and cost-effective option for gender-affirming surgery for transwomen. en-copyright= kn-copyright= en-aut-name=WatanabeShiho en-aut-sei=Watanabe en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeToshiyuki en-aut-sei=Watanabe en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKiyoshi en-aut-sei=Yamada en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaYuzaburo en-aut-sei=Namba en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic Surgery, Kousei Hospital kn-affil= affil-num=4 en-affil=Department of Gender center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= en-keyword=gender-affirming surgery, kn-keyword=gender-affirming surgery, en-keyword=vaginoplasty kn-keyword=vaginoplasty en-keyword=gender incongruence kn-keyword=gender incongruence en-keyword=transwomen kn-keyword=transwomen END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=535 end-page=540 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Psychological Stress Induced by Prone Positioning among Adults with Severe Cerebral Palsy en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this study was to investigate the psychological impact of various positionings in subjects with cerebral palsy (CP). The participants were 17 individuals with severe motor and intellectual disability due to CP. They began in a sitting position in their wheelchair, and were placed consecutively in prone or supine positions, with no intervals between placements. Physiological observations were made in each position, and included salivary α-amylase activity, pulse, percutaneous oxygen saturation, respiratory rate, learance or not of airway secretions, and occurrence or not of adverse events. Salivary α-amylase activity values were higher in the prone position than in the baseline and supine positions (p<0.05). Clearance of airway secretions was significantly more prevalent in the prone position than in the baseline and supine positions (p <0.05). The participants’ pulse was significantly lower in the supine and prone positions than in the baseline position (p<0.05). Greater prevalence of airway secretion clearance and significantly higher stress levels as indicated by saliva amylase were observed in the prone position than in the other two positions. Therefore, when such patients are placed in a prone position, close attention to airway management and the potential for psychological stress may be necessary. en-copyright= kn-copyright= en-aut-name=MatsudaTadashi en-aut-sei=Matsuda en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkezakiYoshiteru en-aut-sei=Akezaki en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujiYoko en-aut-sei=Tsuji en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamadaKazunori en-aut-sei=Hamada en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OokuraMitsuhiro en-aut-sei=Ookura en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Suita Municipal Disability Support Center I-Hope Suita kn-affil= affil-num=2 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= affil-num=3 en-affil=Division of Occupational Therapy, Department of Rehabilitation Sciences, Faculty of Allied Health Sciences, Kansai University of Welfare Sciences kn-affil= affil-num=4 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= affil-num=5 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= en-keyword=alpha-amylase kn-keyword=alpha-amylase en-keyword=stress kn-keyword=stress en-keyword=positioning kn-keyword=positioning en-keyword= cerebral palsy kn-keyword= cerebral palsy en-keyword=severe motor and intellectual disability kn-keyword=severe motor and intellectual disability END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=439 end-page=446 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Social Capital and Post-traumatic Stress Disorder among Heavy Rainfall and Flood Victims in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the relationship between cognitive/structural social capital and post-traumatic stress disorder (PTSD) among victims of heavy rain and flood. Participants were individuals aged≥18 years affected by the July 2018 heavy rainfall in the cities of Kurashiki and Soja, Japan, and living in temporary housing. We distributed five copies of a questionnaire to 1,991 households and received responses from 1,927 individuals (907 men, 1,008 women, 12 respondents of unspecified sex) in 1,029 households (51.7%). We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between high (vs. low) social capital and PTSD or other outcomes. After covariate adjustment, the odds of having PTSD were lower in participants with high cognitive social capital than those with low cognitive social capital (OR=0.346, 95%CI: 0.263-0.456). Elderly women with higher structural social capital tended to have lower PTSD odds than those with lower structural social capital (OR=0.671, 95%CI: 0.431-1.046). The opposite pattern was observed for elderly men (OR=1.315, 95%CI: 0.792-2.183). Cognitive social capital is a protective factor that may reduce PTSD or promote a favorable PTSD prognosis after heavy rainfall and flood events. The associations between structural social capital and PTSD differ by age and sex. en-copyright= kn-copyright= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NoguchiMasayuki en-aut-sei=Noguchi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkazakiTsubasa en-aut-sei=Okazaki en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoShunsuke en-aut-sei=Sato en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Okayama Prefectural Mental Health and Welfare Center kn-affil= affil-num=4 en-affil=Okayama Prefectural Mental Health and Welfare Center kn-affil= affil-num=5 en-affil=Okayama Prefectural Mental Health and Welfare Center kn-affil= affil-num=6 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=social capital kn-keyword=social capital en-keyword=post-traumatic stress disorder kn-keyword=post-traumatic stress disorder en-keyword=disaster kn-keyword=disaster en-keyword=flooding kn-keyword=flooding END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=429 end-page=437 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Association between Preoperative Blood Pressure Elevations and Postoperative Adverse Outcomes after Non-cardiac Surgery: A Single-center Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Blood pressure (BP) often rises before surgery. This study investigated whether BP elevation immediately before surgery was associated with adverse outcomes. Medical records of 11,732 patients (average age: 61 years; male: 47.4%) who underwent non-cardiac elective inpatient surgery under general anesthesia at Kagawa University Hospital between January 2011 and June 2019 were reviewed. Differences between the first BP values measured on the day before surgery and the first BP values in the operating room were defined as Δ systolic BP (ΔSBP) and Δ diastolic BP (ΔDBP). The relationships between ΔSBP/ΔDBP and 30-day mortality, 30-day readmission, and over-the-standard length of hospital stay (OSLOS) were assessed. OSLOS was defined as a hospital stay longer than mean+2 standard deviations and was calculated using the Japanese Diagnosis Procedure Combination data. In univariate analysis, the differences in ΔSBP and ΔDBP between the OSLOS and standard LOS groups were both 2 mmHg. In multivariate logistic regression analysis, only ΔDBP was associated with OSLOS. The adjusted odds ratio (95% confidence interval) for the largest quartile was 1.31 (1.02-1.69) (p<0.05). ΔDBP was associated with OSLOS; however, there may be little need to worry about large ΔSBPs and ΔDBPs in clinical practice. en-copyright= kn-copyright= en-aut-name=YamadoriYusuke en-aut-sei=Yamadori en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Nlandu R.

A total of 84 outpatients on CHD, aged 71.6±11.8 years, were enrolled in this cross-sectional study. Parameters for prolonged sedentary bouts [i.e., ≧ 30 min (% and bout) and ≧ 60 min (% and bout)] were measured using a triaxial accelerometer. Health-related QOL (HRQOL) was evaluated by the Euro-QOL (EQ-5D). Clinical parameters were obtained from medical records. Relatively prolonged sedentary bouts (%) were 44.0±18.2 (≧ 30 min) and 29.8±16.5 (≧ 60 min) for total days. Prolonged sedentary bouts (bouts) were 6.2±2.7 (≧ 30 min) and 2.7±1.6 (≧ 60 min) for total days. EQ-5D scores were 0.728±0.220. All prolonged sedentary bout parameters were negatively correlated with EQ-5D scores, except for prolonged sedentary bouts (≧ 60 min) (min) and relatively prolonged sedentary bouts (%) on hemodialysis days. Multiple regression analysis showed that prolonged sedentary bout parameters were an important factor in EQ-5D scores even after adjusting for confounding factors for total and non-hemodialysis days. Our results suggested that prolonged sedentary bouts were closely associated with HRQOL in patients on CHD, especially on non-hemodialysis days. en-copyright= kn-copyright= en-aut-name=NamioKeiichi en-aut-sei=Namio en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HishiiShuhei en-aut-sei=Hishii en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoTakashi en-aut-sei=Kondo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiHiroyuki en-aut-sei=Nishi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaAkihiko en-aut-sei=Katayama en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UjikeKazuhiro en-aut-sei=Ujike en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoumotoKiichi en-aut-sei=Koumoto en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiHiromi en-aut-sei=Suzuki en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HashimotoHiroo en-aut-sei=Hashimoto en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Innoshima General Hospital kn-affil= affil-num=5 en-affil=Innoshima General Hospital kn-affil= affil-num=6 en-affil=Faculty of Social Studies, Shikokugakuin University kn-affil= affil-num=7 en-affil=Innoshima General Hospital kn-affil= affil-num=8 en-affil=Innoshima General Hospital kn-affil= affil-num=9 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=10 en-affil=Innoshima General Hospital kn-affil= en-keyword=prolonged sedentary bouts kn-keyword=prolonged sedentary bouts en-keyword=hemodialysis kn-keyword=hemodialysis en-keyword=EQ-5D kn-keyword=EQ-5D en-keyword=QOL kn-keyword=QOL END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=5 article-no= start-page=601 end-page=609 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Effect of Peer Instruction Lectures on Learning Attitudes in Epidemiology Education en-subtitle= kn-subtitle= en-abstract= kn-abstract=Research suggests that the fundamental concepts of epidemiology cannot be sufficiently learned in traditional lectures, and interactive learning is necessary. However, few studies have investigated interactive epidemiology education in general, or peer instruction (PI) in particular. This study investigated the effect of PI. Study par-ticipants were fourth-year medical students. The attitude of participants in regard to PI learning was examined in a non-PI and a PI group. The Survey of Attitudes Toward Statistics (SATS) (containing six sub-categories) was conducted as a learning-attitudes index. The pre- and post-lecture scores were compared between the non-PI and PI groups using double robust (DR) estimation. The non-PI and PI groups consisted of 20 and 121 student participants, respectively. In DR estimation, affect exhibited the lowest SATS score changes, at −0.51 (95% confidence interval −0.78 to −0.24; p-value < 0.001), whereas effort exhibited the highest score changes of 0.01 (95% confidence interval −0.30 to 0.32; p-value = 0.952). The epidemiology lecture with PI did not increase the SATS scores. This might be due to issues related to the experimental design. Further research investigating the effects of interactive epidemiology education, it will be necessary to develop tools for assessing the learning of epidemiological concepts and to improve the research design. en-copyright= kn-copyright= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=medical students kn-keyword=medical students en-keyword=peer instruction kn-keyword=peer instruction en-keyword=epidemiological education kn-keyword=epidemiological education en-keyword=learning attitude kn-keyword=learning attitude en-keyword=double robust esti-mation kn-keyword=double robust esti-mation END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=5 article-no= start-page=557 end-page=565 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between Pressure Ulcers in Elderly People and Physiological Indices of the Skin en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the relationship between skin physiological indices and pressure ulcers in elderly people. The subjects were 55 bedridden elderly Japanese patients with a median age of 85 years. The following parame-ters were measured using non-invasive devices: skin surface temperature, moisture content in the stratum corneum, moisture content in the dermis, transepidermal water loss as an index of skin barrier function, skin erythema and skin elasticity. The sacral and 2 heel areas were observed as sites predisposed to pressure ulcers. Within one month after measuring the skin physiological indices, we confirmed pressure ulcers of National Pressure Ulcer Advisory Panel classification Stage II or worse based on medical records. Among the 55 patients, 4 (7.3%) prospectively developed a total of 5 pressure ulcers within 16 days. Only the skin erythema score was significantly higher with than without pressure ulcers (p < 0.001). We performed a binary logistic regression analysis and confirmed a significant relationship between pressure-ulcer development and the level of erythema (odds ratio = 1.026; 95% confidence interval: 1.011-1.042). Skin erythema increased before the development of pressure ulcers. Taken together, our results show that the high skin erythema score can be a predictive indicator of pressure ulcers. en-copyright= kn-copyright= en-aut-name=Takeshima KoharaHiroko en-aut-sei=Takeshima Kohara en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMitsunori en-aut-sei=Ikeda en-aut-mei=Mitsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkawaMasami en-aut-sei=Okawa en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nursing, University of Kochi kn-affil= affil-num=2 en-affil=Department of Nursing, University of Kochi kn-affil= affil-num=3 en-affil=Shiragikuen Hospital kn-affil= en-keyword=elderly people kn-keyword=elderly people en-keyword=erythema kn-keyword=erythema en-keyword=pressure ulcer kn-keyword=pressure ulcer en-keyword=skin kn-keyword=skin END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=14 article-no= start-page=L140402 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spin-gap formation due to spin-Peierls instability in π-orbital-ordered NaO2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have investigated the low-temperature magnetism of sodium superoxide (NaO2), in which spin, orbital, and lattice degrees of freedom are closely entangled. The magnetic susceptibility shows anomalies at T1 = 220 K and T2 = 190 K, which correspond well to the structural phase transition temperatures, and a sudden decrease below T3 = 34 K. At 4.2 K, the magnetization shows a clear stepwise anomaly around 30 T with a large hysteresis. In addition, the muon spin relaxation experiments indicate no magnetic phase transition down to T = 0.3 K. The inelastic neutron scattering spectrum exhibits magnetic excitation with a finite energy gap. These results confirm that the ground state of NaO2 is a spin-singlet state. To understand this ground state in NaO2, we performed Raman scattering experiments. All the Raman-active libration modes expected for the marcasite phase below T2 are observed. Furthermore, we find that several new peaks appear below T3. This directly evidences the low crystal symmetry, namely, the presence of the phase transition at T3.We conclude that the singlet ground state of NaO2 is due to the spin-Peierls instability. en-copyright= kn-copyright= en-aut-name=MiyajimaMizuki en-aut-sei=Miyajima en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AstutiFahmi en-aut-sei=Astuti en-aut-mei=Fahmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukudaTakahito en-aut-sei=Fukuda en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodaniMasashi en-aut-sei=Kodani en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IidaShinsuke en-aut-sei=Iida en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaiShinichiro en-aut-sei=Asai en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuoAkira en-aut-sei=Matsuo en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MasudaTakatsugu en-aut-sei=Masuda en-aut-mei=Takatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KindoKoichi en-aut-sei=Kindo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HasegawaTakumi en-aut-sei=Hasegawa en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KobayashiTatsuo C. en-aut-sei=Kobayashi en-aut-mei=Tatsuo C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakanoTakehito en-aut-sei=Nakano en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WatanabeIsao en-aut-sei=Watanabe en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KambeTakashi en-aut-sei=Kambe en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Advanced Meson Science Laboratory, RIKEN Nishina Center kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= affil-num=6 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= affil-num=7 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= affil-num=8 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= affil-num=9 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= affil-num=10 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=Institute of Quantum Beam Science, Ibaraki University kn-affil= affil-num=13 en-affil=Advanced Meson Science Laboratory, RIKEN Nishina Center kn-affil= affil-num=14 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=9 article-no= start-page=094502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formation of hot ice caused by carbon nanobrushes. II. Dependency on the radius of nanotubes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Stable crystalline structures of confined water can be different from bulk ice. In Paper I [T. Yagasaki et al., J. Chem. Phys. 151, 064702 (2019)] of this study, it was shown, using molecular dynamics (MD) simulations, that a zeolite-like ice structure forms in nanobrushes consisting of (6,6) carbon nanotubes (CNTs) when the CNTs are located in a triangle arrangement. The melting temperature of the zeolite-like ice structure is much higher than the melting temperature of ice Ih when the distance between the surfaces of CNTs is ∼0.94 nm, which is the best spacing for the bilayer structure of water. In this paper, we perform MD simulations of nanobrushes of CNTs that are different from (6,6) CNTs in radius. Several new porous ice structures form spontaneously in the MD simulations. A stable porous ice forms when the radius of its cavities matches the radius of the CNTs well. All cylindrical porous ice structures found in this study can be decomposed into a small number of structural blocks. We provide a new protocol to classify cylindrical porous ice crystals on the basis of this decomposition. en-copyright= kn-copyright= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=093056 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Superconductivity in a new layered triangular-lattice system Li2IrSi2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report on the crystal structure and superconducting properties of a novel iridium-silicide, namely Li2IrSi2. It has a Ag2NiO2-type structure (space group R-3m) with the lattice parameters a = 4.028 30(6) Å and c = 13.161 80(15) Å. The crystal structure comprises IrSi2 and double Li layers stacked alternately along the c-axis. The IrSi2 layer includes a two-dimensional Ir equilateral-triangular lattice. Electrical resistivity and static magnetic measurements revealed that Li2IrSi2 is a type-II superconductor with critical temperature (Tc) of 3.3 K. We estimated the following superconducting parameters: lower critical field Hc1(0) ~ 42 Oe, upper critical field Hc2(0) ~ 1.7 kOe, penetration depth λ0 ~ 265 nm, coherence length ξ0 ~ 44 nm, and Ginzburg–Landau parameter κGL ~ 6.02. The specific-heat data suggested that superconductivity in Li2IrSi2 could be attributed to weak-coupling Cooper pairs. en-copyright= kn-copyright= en-aut-name=HoriganeK en-aut-sei=Horigane en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiK en-aut-sei=Takeuchi en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HyakumuraD en-aut-sei=Hyakumura en-aut-mei=D kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HorieR en-aut-sei=Horie en-aut-mei=R kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoT en-aut-sei=Sato en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuranakaT en-aut-sei=Muranaka en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawashimaK en-aut-sei=Kawashima en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiiH en-aut-sei=Ishii en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KubozonoY en-aut-sei=Kubozono en-aut-mei=Y kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OrimoS en-aut-sei=Orimo en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IsobeM en-aut-sei=Isobe en-aut-mei=M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkimitsuJ en-aut-sei=Akimitsu en-aut-mei=J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University, kn-affil= affil-num=2 en-affil=Graduate School of natural science and technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics and Mathematics, Aoyama Gakuin University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for Materials Research, Tohoku University kn-affil= affil-num=6 en-affil=Department of Engineering Science, University of Electro-Communications kn-affil= affil-num=7 en-affil=Department of Physics and Mathematics, Aoyama Gakuin University kn-affil= affil-num=8 en-affil=National Synchrotron Radiation Research Center kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Institute for Materials Research, Tohoku University kn-affil= affil-num=11 en-affil=National Institute for Materials Science (NIMS) kn-affil= affil-num=12 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=supreconductivity kn-keyword=supreconductivity en-keyword=iridium-silicide kn-keyword=iridium-silicide en-keyword=spin–orbit coupling kn-keyword=spin–orbit coupling END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=3 article-no= start-page=035501 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Soft x-ray irradiation induced metallization of layered TiNCl en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have performed soft x-ray spectroscopy in order to study the photoirradiation time dependence of the valence band structure and chemical states of layered transition metal nitride chloride TiNCl.

These results indicate the photo-induced metallization originates from deintercalation due to Cl desorption, and thus provide a new carrier doping method that controls the conducting properties of TiNCl. en-copyright= kn-copyright= en-aut-name=KataokaNoriyuki en-aut-sei=Kataoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasashi en-aut-sei=Tanaka en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HosodaWataru en-aut-sei=Hosoda en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiTakumi en-aut-sei=Taniguchi en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimoriShin-ichi en-aut-sei=Fujimori en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WakitaTakanori en-aut-sei=Wakita en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Engineering, Kyushu Institute of Technology kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Materials Sciences Research Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=1 article-no= start-page=012001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sparse Modeling in Quantum Many-Body Problems en-subtitle= kn-subtitle= en-abstract= kn-abstract=This review paper describes the basic concept and technical details of sparse modeling and its applications to quantum many-body problems. Sparse modeling refers to methodologies for finding a small number of relevant parameters that well explain a given dataset. This concept reminds us physics, where the goal is to find a small number of physical laws that are hidden behind complicated phenomena. Sparse modeling extends the target of physics from natural phenomena to data, and may be interpreted as “physics for data”. The first half of this review introduces sparse modeling for physicists. It is assumed that readers have physics background but no expertise in data science. The second half reviews applications. Matsubara Green’s function, which plays a central role in descriptions of correlated systems, has been found to be sparse, meaning that it contains little information. This leads to (i) a new method for solving the ill-conditioned inverse problem for analytical continuation, and (ii) a highly compact representation of Matsubara Green’s function, which enables efficient calculations for quantum many-body systems. en-copyright= kn-copyright= en-aut-name=OtsukiJunya en-aut-sei=Otsuki en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhzekiMasayuki en-aut-sei=Ohzeki en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShinaokaHiroshi en-aut-sei=Shinaoka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshimiKazuyoshi en-aut-sei=Yoshimi en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Information Sciences, Tohoku University kn-affil= affil-num=3 en-affil=Department of Physics, Saitama University kn-affil= affil-num=4 en-affil=4Institute for Solid State Physics, University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=45 article-no= start-page=26686 end-page=26692 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new protocol for the preparation of superconducting KBi2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A superconducting KBi2 sample was successfully prepared using a liquid ammonia (NH3) technique. The temperature dependence of the magnetic susceptibility (M/H) showed a superconducting transition temperature (Tc) as high as 3.6 K. In addition, the shielding fraction at 2.0 K was evaluated to be 87%, i.e., a bulk superconductor was realized using the above method. The Tc value was the same as that reported for the KBi2 sample prepared using a high-temperature annealing method. An X-ray diffraction pattern measured based on the synchrotron X-ray radiation was analyzed using the Rietveld method, with a lattice constant, a, of 9.5010(1) Å under the space group of Fd[3 with combining macron]m (face-centered cubic, no. 227). The lattice constant and space group found for the KBi2 sample using a liquid NH3 technique were the same as those reported for KBi2 through a high-temperature annealing method. Thus, the superconducting behavior and crystal structure of the KBi2 sample obtained in this study are almost the same as those for the KBi2 sample reported previously. Strictly speaking, the magnetic behavior of the superconductivity was different from that of a KBi2 sample reported previously, i.e., the KBi2 sample prepared using a liquid NH3 technique was a type-II like superconductor, contrary to that prepared using a high-temperature annealing method, the reason for which is fully discussed. These results indicate that the liquid NH3 technique is effective and simple for the preparation of a superconducting KBi2. In addition, the topological nature of the superconductivity for KBi2 was not confirmed. en-copyright= kn-copyright= en-aut-name=LiHuan en-aut-sei=Li en-aut-mei=Huan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangYanan en-aut-sei=Wang en-aut-mei=Yanan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyamaSaki en-aut-sei=Nishiyama en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangXiaofan en-aut-sei=Yang en-aut-mei=Xiaofan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaguchiTomoya en-aut-sei=Taguchi en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiuraAkari en-aut-sei=Miura en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiAi en-aut-sei=Suzuki en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ZhiLei en-aut-sei=Zhi en-aut-mei=Lei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GotoHidenori en-aut-sei=Goto en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EguchiRitsuko en-aut-sei=Eguchi en-aut-mei=Ritsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KambeTakashi en-aut-sei=Kambe en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=LiaoYen-Fa en-aut-sei=Liao en-aut-mei=Yen-Fa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IshiiHirofumi en-aut-sei=Ishii en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=National Synchrotron Radiation Research Center kn-affil= affil-num=13 en-affil=National Synchrotron Radiation Research Center kn-affil= affil-num=14 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=3 article-no= start-page=602 end-page=611 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190722 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Initial Evaluation of AF78: a Rationally Designed Fluorine-18-Labelled PET Radiotracer Targeting Norepinephrine Transporter en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Taking full advantage of positron emission tomography (PET) technology, fluorine-18-labelled radiotracers targeting norepinephrine transporter (NET) have potential applications in the diagnosis and assessment of cardiac sympathetic nerve conditions as well as the delineation of neuroendocrine tumours. However, to date, none have been used clinically. Drawbacks of currently reported radiotracers include suboptimal kinetics and challenging radiolabelling procedures.
Procedures
We developed a novel fluorine-18-labelled radiotracer targeting NET, AF78, with efficient one-step radiolabelling based on the phenethylguanidine structure. Radiosynthesis of AF78 was undertaken, followed by validation in cell uptake studies, autoradiography, and in vivo imaging in rats.
Results
[18F]AF78 was successfully synthesized with 27.9 ± 3.1 % radiochemical yield, > 97 % radiochemical purity and > 53.8 GBq/mmol molar activity. Cell uptake studies demonstrated essentially identical affinity for NET as norepinephrine and meta-iodobenzylgaunidine. Both ex vivo autoradiography and in vivo imaging in rats showed homogeneous and specific cardiac uptake.
Conclusions
The new PET radiotracer [18F]AF78 demonstrated high affinity for NET and favourable biodistribution in rats. A structure-activity relationship between radiotracer structures and affinity for NET was revealed, which may serve as the basis for the further design of NET targeting radiotracers with favourable features. en-copyright= kn-copyright= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FritzAlexander en-aut-sei=Fritz en-aut-mei=Alexander kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YagiYusuke en-aut-sei=Yagi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraHiroyuki en-aut-sei=Kimura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RoweSteven P. en-aut-sei=Rowe en-aut-mei=Steven P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoshinoKazuhiro en-aut-sei=Koshino en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DeckerMichael en-aut-sei=Decker en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Nuclear Medicine, University Hospital of Würzburg kn-affil= affil-num=2 en-affil=Institute of Pharmacy and Food Chemistry, University of Würzburg kn-affil= affil-num=3 en-affil=Department of Nuclear Medicine, University Hospital of Würzburg kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Analytical and Bioinorganic Chemistry, Division of Analytical and Physical Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Department of Analytical and Bioinorganic Chemistry, Division of Analytical and Physical Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=7 en-affil=Division of Nuclear Medicine and Molecular Imaging, Russel H.

These systems benefit from less labour-intensive maintenance and quality control as fewer prone parts are moving, higher accuracy for focused scans and maintaining high resolution with increased sensitivity due to focused pinholes on the field of view. This study aims to investigate the performance of a novel ultra-high-resolution scanner with two-detector configuration (U-SPECT5-E) and to compare its image quality to a conventional micro-SPECT system with three stationary detectors (U-SPECT+). Methods The new U-SPECT5-E with two stationary detectors was used for acquiring data with Tc-99m-filled point source, hot-rod and uniformity phantoms to analyse sensitivity, spatial resolution, uniformity and contrast-to-noise ratio (CNR). Three dedicated multi-pinhole mouse collimators with 75 pinholes each and 0.25-, 0.60- and 1.00-mm pinholes for extra ultra-high resolution (XUHR-M), general-purpose (GP-M) and ultra-high sensitivity (UHS-M) imaging were examined. For CNR analysis, four different activity ranges representing low- and high-count settings were investigated for all three collimators. The experiments for the performance assessment were repeated with the same GP-M collimator in the three-detector U-SPECT+ for comparison. Results Peak sensitivity was 237 cps/MBq (XUHR-M), 847 cps/MBq (GP-M), 2054 cps/MBq (UHS-M) for U-SPECT5-E and 1710 cps/MBq (GP-M) for U-SPECT+. In the visually analysed sections of the reconstructed mini Derenzo phantoms, rods as small as 0.35 mm (XUHR-M), 0.50 mm (GP-M) for the two-detector as well as the three-detector SPECT and 0.75 mm (UHS-M) were resolved. Uniformity for maximum resolution recorded 40.7% (XUHR-M), 29.1% (GP-M, U-SPECT5-E), 16.3% (GP-M, U-SPECT+) and 23.0% (UHS-M), respectively. UHS-M reached highest CNR values for low-count images; for rods smaller than 0.45 mm, acceptable CNR was only achieved by XUHR-M. GP-M was superior for imaging rods sized from 0.60 to 1.50 mm for intermediate activity concentrations. U-SPECT5-E and U-SPECT+ both provided comparable CNR. Conclusions While uniformity and sensitivity are negatively affected by the absence of a third detector, the investigated U-SPECT5-E system with two stationary detectors delivers excellent spatial resolution and CNR comparable to the performance of an established three-detector-setup. en-copyright= kn-copyright= en-aut-name=HoffmannJan, V en-aut-sei=Hoffmann en-aut-mei=Jan, V kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=JanssenJan P. en-aut-sei=Janssen en-aut-mei=Jan P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KannoTakayuki en-aut-sei=Kanno en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShibutaniTakayuki en-aut-sei=Shibutani en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoguchiMasahisa en-aut-sei=Onoguchi en-aut-mei=Masahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LapaConstantin en-aut-sei=Lapa en-aut-mei=Constantin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GrunzJan-Peter en-aut-sei=Grunz en-aut-mei=Jan-Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BuckAndreas K. en-aut-sei=Buck en-aut-mei=Andreas K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Nuclear Medicine, University Hospital Würzburg kn-affil= affil-num=2 en-affil=Department of Nuclear Medicine, University Hospital Würzburg kn-affil= affil-num=3 en-affil=Comprehensive Heart Failure Center, University Hospital Würzburg kn-affil= affil-num=4 en-affil=Department of Quantum Medical Technology, Graduate School of Medical Sciences kn-affil= affil-num=5 en-affil=Department of Quantum Medical Technology, Graduate School of Medical Sciences kn-affil= affil-num=6 en-affil=Nuclear Medicine, Medical Faculty, University of Augsburg kn-affil= affil-num=7 en-affil=Department of Diagnostic and Interventional Radiology, University Hospital Würzburg kn-affil= affil-num=8 en-affil=Department of Nuclear Medicine, University Hospital Würzburg kn-affil= affil-num=9 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Small-animal imaging kn-keyword=Small-animal imaging en-keyword=SPECT kn-keyword=SPECT en-keyword=Mouse kn-keyword=Mouse en-keyword=Collimator kn-keyword=Collimator en-keyword=Post-reconstruction filtering kn-keyword=Post-reconstruction filtering END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=5 article-no= start-page=391 end-page=399 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three-dimensional Evaluation of Abnormal Gait in Patients with Hip Osteoarthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Indexes for objectively evaluating abnormal gait in hip osteoarthritis (OA) patients and determining effective interventions are unclear. We analyzed the abnormal gait of hip OA patients by focusing on movements of the trunk and pelvis to establish an effective evaluation index for each direction of motion. We studied 28 patients with secondary hip OA due to developmental dysplasia of the hip and 16 controls. The trunk and pelvic movements during gait were measured in the medial-lateral (x), vertical (y), and back-and-forth (z) directions by a triaxial angular accelerometer. Gait speed, steps, step length, muscle strength, range of motion, and timed up-and-go (TUG) test performance were measured. We determined the correlations between physical function and the index of abnormal gait in the hip OA patients. Movements other than trunk and pelvic motions in the y-direction indicated abnormal gait in the patients. Significant correlations were found between abnormal gait and range of motions (extension, internal rotation), TUG score, stride length, and steps. The TUG test, stride length and steps were important for evaluating abnormal gait in hip OA patients. Individual interventions for each movement direction are required. en-copyright= kn-copyright= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MinatoIzumi en-aut-sei=Minato en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyasakaDai en-aut-sei=Miyasaka en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakaifYoshinori en-aut-sei=Sakaif en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimadaHayato en-aut-sei=Shimada en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DohmaeYoichiro en-aut-sei=Dohmae en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EndoNaoto en-aut-sei=Endo en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Orthopedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopedic Surgery, Niigata Rinko Hospital kn-affil= affil-num=3 en-affil=Division of Comprehensive Geriatrics in Community, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=5 en-affil=Division of Orthopedic Surgery, Niigata General Hospital kn-affil= affil-num=6 en-affil=Division of Orthopedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Division of Orthopedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=8 en-affil=Division of Orthopedic Surgery, Mito Saiseikai General Hospital kn-affil= affil-num=9 en-affil=Division of Orthopedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=10 en-affil=Division of Orthopedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= en-keyword=hip osteoarthritis kn-keyword=hip osteoarthritis en-keyword=three-dimensional gait analysis kn-keyword=three-dimensional gait analysis en-keyword=abnormal gait kn-keyword=abnormal gait en-keyword=timed up and go test kn-keyword=timed up and go test en-keyword=range of motion kn-keyword=range of motion END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=22 article-no= start-page=7422 end-page=7435 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of [7]phenacene incorporating tetradecyl chains in the axis positions and its application in field-effect transistors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Field-effect transistors (FETs) were fabricated using a new type of phenacene molecule, 3,12-ditetradecyl[7]phenacene ((C14H29)2-[7]phenacene), and solid gate dielectrics or an electric double layer (EDL) capacitor with an ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate (bmim[PF6])). The new molecule, (C14H29)2-[7]phenacene, was efficiently synthesized via the Mallory photoreaction. Its crystal structure and electronic properties were determined, using X-ray diffraction, scanning tunneling microscopy/spectroscopy (STM and STS), absorption spectroscopy, and photoelectron yield spectroscopy, which showed a monoclinic crystal lattice (space group P21 (no. 4)) and an energy gap of ∼3.0 eV. The STM image clearly showed the molecular structure of (C14H29)2-[7]phenacene, as well as the closed molecular stacking, indicative of a strong fastener effect between alkyl chains. The X-ray diffraction pattern of thin films of (C14H29)2-[7]phenacene formed on a SiO2/Si substrate suggested that the molecule stood on the surface with an inclined angle of 30° with respect to the normal axis of the surface. The FET properties were recorded in two-terminal measurement mode, showing p-channel normally-off characteristics. The averaged values of field-effect mobility, μ, were 1.6(3) cm2 V−1 s−1 for a (C14H29)2-[7]phenacene thin-film FET with a SiO2 gate dielectric and 6(4) × 10−1 cm2 V−1 s−1 for a (C14H29)2-[7]phenacene thin-film EDL FET with bmim[PF6]. Thus, higher FET performance was obtained with an FET using a thin film of (C14H29)2-[7]phenacene compared to parent [7]phenacene. This study could pioneer an avenue for the realization of high-performance FETs through the addition of alkyl chains to phenacene molecules. en-copyright= kn-copyright= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamaoShino en-aut-sei=Hamao en-aut-mei=Shino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KozasaKeiko en-aut-sei=Kozasa en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYanan en-aut-sei=Wang en-aut-mei=Yanan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PanYong-He en-aut-sei=Pan en-aut-mei=Yong-He kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YenYu-Hsiang en-aut-sei=Yen en-aut-mei=Yu-Hsiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HoffmannGermar en-aut-sei=Hoffmann en-aut-mei=Germar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=GotoKenta en-aut-sei=Goto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Physics & Center for Quantum Technology, National Tsing Hua University kn-affil= affil-num=7 en-affil=Department of Physics & Center for Quantum Technology, National Tsing Hua University kn-affil= affil-num=8 en-affil=Department of Physics & Center for Quantum Technology, National Tsing Hua University kn-affil= affil-num=9 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=10 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=221 end-page=227 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Possible Protective Effect of the 'Cam Deformity' on Femoral Neck Fracture: The Relationship between Hip Morphology and the Types of Hip Fracture en-subtitle= kn-subtitle= en-abstract= kn-abstract=We retrospectively evaluated the cases of 169 hip fracture patients, their previous fractures, and the contralateral hip joint’s morphology. A history of contralateral hip fracture was present in 23 patients (Contra group). The other patients had a unilateral hip fracture: a trochanteric fracture (Troch group, n=73) or a femoral neck fracture (Neck group, n=73). In the Troch and Neck groups, we used anteroposterior and cross-table axialview radiographs of the contralateral hip to evaluate the proximal femur’s anatomy. In the Contra group, the concordance rate between the first and second types of hip fracture was 65.2%, and the second hip fracture’s morphology indicated that the trochanteric fracture had a cam deformity in terms of the femoral head-neck ratio. The average alpha angle and femoral head-neck offset in the Troch group were significantly larger than those in the Neck group. In the Neck group, pistol-grip deformities of Arbeitsgemeinschaft für Osteosynthesefragen types B1 (subcapital), B2 (transcervical), and B3 (displaced) were observed in 42.1%, 75%, and 6% of cases, respectively. There was a smaller alpha angle and a larger femoral head-neck offset in the contralateral hip of femoral neck fractures; thus, the “cam deformity” may protect against femoral neck fractures. en-copyright= kn-copyright= en-aut-name=YaguraTakuma en-aut-sei=Yagura en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OeKenichi en-aut-sei=Oe en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PakuMasaaki en-aut-sei=Paku en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TajimaTakeshi en-aut-sei=Tajima en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraMasaya en-aut-sei=Nakamura en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IidaHirokazu en-aut-sei=Iida en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoTakanori en-aut-sei=Saito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Osaka Saiseikai Izuo Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Meisei Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, McSYL Tatsumi Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= en-keyword=cam deformity kn-keyword=cam deformity en-keyword=femoral neck fracture kn-keyword=femoral neck fracture en-keyword=trochanteric fracture kn-keyword=trochanteric fracture en-keyword=bilateral hip fractures kn-keyword=bilateral hip fractures END start-ver=1.4 cd-journal=joma no-vol=959 cd-vols= no-issue= article-no= start-page=163549 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of gadolinium’s action on water Cherenkov detector systems with EGADS en-subtitle= kn-subtitle= en-abstract= kn-abstract= Used for both proton decay searches and neutrino physics, large water Cherenkov (WC) detectors have been very successful tools in particle physics. They are notable for their large masses and charged particle detection capabilities. While current WC detectors reconstruct charged particle tracks over a wide energy range, they cannot efficiently detect neutrons. Gadolinium (Gd) has the largest thermal neutron capture cross section of all stable nuclei and produces an 8 MeV gamma cascade that can be detected with high efficiency. Because of the many new physics opportunities that neutron tagging with a Gd salt dissolved in water would open up, a large-scale R&D program called EGADS was established to demonstrate this technique’s feasibility. EGADS features all the components of a WC detector, chiefly a 200-ton stainless steel water tank furnished with 240 photo-detectors, DAQ, and a water system that removes all impurities from water while keeping Gd in solution. In this paper we discuss the milestones towards demonstrating the feasibility of this novel technique, and the features of EGADS in detail. en-copyright= kn-copyright= en-aut-name=MartiLl.

Single-Pill Therapy in Japanese Outpatients en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study examined whether switching from amlodipine and atorvastatin treatment using two pills to an equal dose of single-pill therapy is useful in Japanese outpatients. We retrospectively reviewed data obtained from 94 outpatients for whom treatment with two pills, namely amlodipine and atorvastatin, was switched to an equal dose of single-pill therapy in 11 hospitals. The criterion for enrollment in this study was that patients had switched their medication without changing other anti-hypertensive or anti-cholesterol drugs. Neither systolic nor diastolic blood pressure changed significantly after switching to an equal dose of single-pill therapy, whereas low-density lipoprotein (LDL) cholesterol levels significantly decreased after the medication was switched from 94±24 mg/dl to 89±17 mg/dl (p=0.015). A switch from medication with two separate pills of amlodipine and atorvastatin to an equal dose of single-pill therapy resulted in an overall decrease in LDL cholesterol. The results indicated that the switch to single-pill therapy might be a useful treatment. en-copyright= kn-copyright= en-aut-name=KawadaYasumasa en-aut-sei=Kawada en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuboToru en-aut-sei=Kubo en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BabaYuichi en-aut-sei=Baba en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirotaTakayoshi en-aut-sei=Hirota en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaniokaKatsutoshi en-aut-sei=Tanioka en-aut-mei=Katsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamasakiNaohito en-aut-sei=Yamasaki en-aut-mei=Naohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitaokaHiroaki en-aut-sei=Kitaoka en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=2 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=3 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=4 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=5 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=6 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=7 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= en-keyword=hypertension kn-keyword=hypertension en-keyword=dyslipidemia kn-keyword=dyslipidemia en-keyword=single-pill therapy kn-keyword=single-pill therapy END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=183 end-page=197 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Childcare Practice Study of Rythmique that Draws Proactive Physical Expression from Children (1st Report) : Mainly Including Cases of Classes for One, Two, and Three Years Old in a Childcare Facility kn-title=子どもの主体的な身体表現を引き出すリトミックの保育実践研究（第一報）: 保育施設における１･２･３歳児学級の事例を中心にして en-subtitle= kn-subtitle= en-abstract= When we outline recent prior-research with key words, “physical expression”,“music education”, “Rythmique” , and “play” , it was clarified that how we consider Rythmique had been changed in the history over 100 years and new study for Rythmique practice is required. Accordingly, this article discussed what children learn from Rythmique practice in a childcare facility and what is grown. As the result, the followings were suggested. i. One years old children are in a phase where they actively imitate their guardians. ii. For a class for two years old children, guardians need to take care of children so that they can freely express. iii. For a class for three years old children, it is important to feel comfort by which their mind can be released and concentrate on a subject of Rythmique or appearance of guardians, and feel pleasure to achieve something through how fun it is to exp ress. kn-abstract= 近年の先行研究を「身体表現」「音楽教育」「リトミック」「遊戯」をキーワードに概観すると，100 年を超える歴史の中で，リトミックの捉え方が変容していることと，リトミックの新しい保育実践研究が必要であることが，明らかになった。そこで本論では，保育施設におけるリトミックの実践から，子どもが何を学び，何が育っているのかを論考した。その結果，以下のことが示唆された。(1)１歳児学級の子どもは，保育者の模倣を活発に行う段階である。(2)２歳児学級においては，子どもが自由に想像し表現できるよう，保育者は，配慮する必要がある。(3)３歳児学級においては，表現することの楽しさを通して心が解放される気持ち良さを感じることや，リトミックの主題や保育者の姿に集中することや，何かを達成する喜びを感じること等が重要である。 en-copyright= kn-copyright= en-aut-name=KOTAKESaori en-aut-sei=KOTAKE en-aut-mei=Saori kn-aut-name=小竹沙織 kn-aut-sei=小竹 kn-aut-mei=沙織 aut-affil-num=1 ORCID= en-aut-name=BABANoriko en-aut-sei=BABA en-aut-mei=Noriko kn-aut-name=馬場訓子 kn-aut-sei=馬場 kn-aut-mei=訓子 aut-affil-num=2 ORCID= en-aut-name=TAKAHASHIKei en-aut-sei=TAKAHASHI en-aut-mei=Kei kn-aut-name=髙橋慧 kn-aut-sei=髙橋 kn-aut-mei=慧 aut-affil-num=3 ORCID= en-aut-name=WATANABEYuzo en-aut-sei=WATANABE en-aut-mei=Yuzo kn-aut-name=渡邊祐三 kn-aut-sei=渡邊 kn-aut-mei=祐三 aut-affil-num=4 ORCID= en-aut-name=TAKAHASHIToshiyuki en-aut-sei=TAKAHASHI en-aut-mei=Toshiyuki kn-aut-name=髙橋敏之 kn-aut-sei=髙橋 kn-aut-mei=敏之 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=御南まんまるこども園 affil-num=2 en-affil= kn-affil=くらしき作陽大学子ども教育学部子ども教育学科 affil-num=3 en-affil= kn-affil=作陽音楽短期大学音楽学科 affil-num=4 en-affil= kn-affil=兵庫教育大学大学院連合学校教育学研究科 affil-num=5 en-affil= kn-affil=岡山大学大学院教育学研究科 en-keyword=子ども (Child (Children)) kn-keyword=子ども (Child (Children)) en-keyword=身体表現 (Physical expression) kn-keyword=身体表現 (Physical expression) en-keyword=リトミック (Rythmique) kn-keyword=リトミック (Rythmique) en-keyword=保育実践 (Childcare practice) kn-keyword=保育実践 (Childcare practice) en-keyword=１･２･３歳児学級 (Classes for One, Two, and Three Years Old) kn-keyword=１･２･３歳児学級 (Classes for One, Two, and Three Years Old) END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=220 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Single-session esophagogastroduodenoscopy and endoscopic ultrasound using a forward-viewing radial scan ultrasonic endoscope en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Endoscopic ultrasound is useful for obtaining high-resolution images of pancreaticobiliary diseases, but is not readily available for physical checkups. In this study, we evaluated the safety and efficacy of single-session esophagogastroduodenoscopy and endoscopic ultrasound in the detection of upper-gastrointestinal and pancreaticobiliary diseases using a forward-viewing radial scan ultrasonic endoscope.
Methods: A total of 148 patients who were scheduled for upper-gastrointestinal screening using an endoscope were prospectively included. All patients were examined by EUS in combination with EGD using a forward-viewing radial scan ultrasonic endoscope. The primary endpoint was the safety of the procedures. The secondary endpoints were the prevalence of diseases, the basal imaging capability of EUS, the procedure time, total dose of propofol, and the correlation between background factors and the prevalence of pancreatic disease. The imaging capability at each region was scored as 0 (invisible) to 2 (sufficient visualization to evaluate the organs).
Results: Intraoperative hypotension occurred as an adverse event of intravenous anesthesia in one patient. There were 82 pancreaticobiliary findings and 165 upper-gastrointestinal findings (malignancy not included). Follicular lymphoma of the intra-abdominal lymph nodes was detected in one patient. The mean imaging scores of each section were 1.95 (pancreatic head and papilla), 2.0 (pancreatic body), 1.99 (pancreatic tail), and 1.89 (common bile duct and gallbladder). Age, history of diabetes mellitus, and smoking history were significantly associated with the prevalence of pancreatic diseases.
Conclusion: The simultaneous performance of EGD and EUS using a new ultrasonic endoscope is tolerable and safe for upper-gastrointestinal and pancreaticobiliary screening. en-copyright= kn-copyright= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiharaYuki en-aut-sei=Ishihara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaragaiYosuke en-aut-sei=Saragai en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakadaSaimon en-aut-sei=Takada en-aut-mei=Saimon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YabeShuntaro en-aut-sei=Yabe en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MuroShinichiro en-aut-sei=Muro en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= en-keyword=Endoscopic ultrasound kn-keyword=Endoscopic ultrasound en-keyword=Diagnostic screening program kn-keyword=Diagnostic screening program en-keyword=Pancreatic diseases kn-keyword=Pancreatic diseases en-keyword=Biliary tract diseases kn-keyword=Biliary tract diseases END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=104666 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dataset of characteristic remanent magnetization and magnetic properties of early Pliocene sediments from IODP Site U1467 (Maldives platform) en-subtitle= kn-subtitle= en-abstract= kn-abstract=This data article describes data of magnetic stratigraphy and anisotropy of isothermal remanent magnetization (AIRM) from "Magnetic properties of early Pliocene sediments from IODP Site U1467 (Maldives platform) reveal changes in the monsoon system" [1].

The proposed process is a collective, coherent Raman scattering followed by neutrino-pair emission from | e of a long lifetime to | g ;.0 + | e .. + i j.i. j + | g with.i. j consisting of six massive neutrino-pairs. Calculated angular distribution has six (i j) thresholds which showup as steps at different angles. Angular locations of thresholds and event rates of the angular distribution make it possible to experimentally determine the smallest neutrino mass to the level of less than several meV, (accordingly all threemasses using neutrino oscillation data), the mass ordering pattern, normal or inverted, and to distinguish whether neutrinos are ofMajorana or Dirac type. Event rates of neutrino-pair emission, when the mechanism of macroscopic coherence amplification works, may become large enough for realistic experiments by carefully selecting certain types of target. The problem to be overcome is macro-coherently amplified quantum electrodynamic background of the process,.0 + | e .. +.2 +.3 + | g , when two extra photons,.2,.3, escape detection.

It is diagnosed based on an individual’s bone mineral density (BMD) or a fracture without trauma. BMD is usually measured by the dual energy X-ray absorptiometry (DXA) method. Here we investigated factors for the earliest possible prediction of decreased BMD by examining the relationships between patients’ BMD values and changes in the patients’ physical and laboratory values. We retrospectively reviewed the medical records of 149 patients who visited our department in 2014-2015 for a variety of reasons and underwent an area BMD examination by DXA. We analyzed the relationships between decreasing BMD and the patients’ gender, age, body mass index (BMI), medical background, hemoglobin, electrolytes, and thyroid function. Thirty-nine of the patients were diagnosed with osteoporosis based on their T-scores. An adjusted analysis showed that female gender, aging, and increased serum calcium level were significantly related to decreasing femoral BMD, whereas high BMI was associated with an increase in femoral BMD. Collectively the results indicate that for the early detection of low BMD, it is important for general-practice physicians to consider conducting a BMD checkup when treating female and elderly patients with a low BMI and/or elevated serum calcium level. en-copyright= kn-copyright= en-aut-name=AndoAkemi en-aut-sei=Ando en-aut-mei=Akemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Honda Mitsugi en-aut-sei=Honda en-aut-mei= Mitsugi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Radiology, Department of Medical Technology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone mineral density (BMD) kn-keyword=bone mineral density (BMD) en-keyword=body mass index (BMI) kn-keyword=body mass index (BMI) en-keyword=female gender kn-keyword=female gender en-keyword=hypercalcemia kn-keyword=hypercalcemia en-keyword=osteoporosis kn-keyword=osteoporosis END start-ver=1.4 cd-journal=joma no-vol=2011 cd-vols= no-issue= article-no= start-page=161 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Green Infrastructure for Asian Cities: The Spatial Concepts and Planning Strategies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Urbanization is a global trend, particularly strong in many Asian countries, Africa, and some Lain American counties now. Designing and planning for sustainable and low-carbon cities is a complex process addressing the fundamental areas of economic, environmental, and social-equitable sustainability. This paper focuses on the environmental aspect with theories and applications of green infrastructure to support ecological and physical processes in urban regions including: hydrology, biodiversity, and cultural/recreational activities. Green infrastructure is an interconnected network of waterways, hybrid hydrological/drainage systems, wetlands, both designed and natural green spaces, working farms and other cultural landscapes, and built infrastructure that provides ecological functions. Green infrastructure plans apply key principles of landscape ecology to urban regions, specifically: a multi-scale approach with explicit attention to the pattern and process relationship and an emphasis on connectivity. Although green infrastructure concept and practice are gaining popularity in North America, the UK, and Europe, its systematic application in Asian cities and urban planning policies is yet to be seen. Through the examination of five case studies of green infrastructure-like approaches to address urban greenspace planning issues in Japan, important GI principles are distilled and the lessons learned from these cases are used to develop specific recommendations to facilitate further application of the GI concept in Asian cities. GI is argued to become a useful greenspace planning tool to protect important and fragile green spaces, mitigate the lost nature, and create new green spaces in the city. Four general design and planning guidelines of green infrastructure are proposed. Based on the lessons learned from the case studies and the preceding argument, the paper concludes with recommendation of four areas of application of the green infrastructure concept to Asian cities. en-copyright= kn-copyright= en-aut-name=KatoSadahisa en-aut-sei=Kato en-aut-mei=Sadahisa kn-aut-name=加藤禎久 kn-aut-sei=加藤 kn-aut-mei=禎久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=グローバル人材育成院 en-keyword=green infrastructure kn-keyword=green infrastructure en-keyword=sustainability kn-keyword=sustainability en-keyword=urbanization kn-keyword=urbanization en-keyword=landscape ecology kn-keyword=landscape ecology en-keyword=connectivity kn-keyword=connectivity en-keyword=multi-scale approach kn-keyword=multi-scale approach END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=e30246 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic clustering of dynamin-amphiphysin helices regulates membrane constriction and fission coupled with GTP hydrolysis en-subtitle= kn-subtitle= en-abstract= kn-abstract= Dynamin is a mechanochemical GTPase essential for membrane fission during clathrin-mediated endocytosis. Dynamin forms helical complexes at the neck of clathrin-coated pits and their structural changes coupled with GTP hydrolysis drive membrane fission. Dynamin and its binding protein amphiphysin cooperatively regulate membrane remodeling during the fission, but its precise mechanism remains elusive. In this study, we analyzed structural changes of dynamin-amphiphysin complexes during the membrane fission using electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM). Interestingly, HS-AFM analyses show that the dynamin-amphiphysin helices are rearranged to form clusters upon GTP hydrolysis and membrane constriction occurs at protein-uncoated regions flanking the clusters. We also show a novel function of amphiphysin in size control of the clusters to enhance biogenesis of endocytic vesicles. Our approaches using combination of EM and HS-AFM clearly demonstrate new mechanistic insights into the dynamics of dynamin-amphiphysin complexes during membrane fission. en-copyright= kn-copyright= en-aut-name=TakedaTetsuya en-aut-sei=Takeda en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KozaiToshiya en-aut-sei=Kozai en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangHuiran en-aut-sei=Yang en-aut-mei=Huiran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikuroDaiki en-aut-sei=Ishikuro en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SeyamaKaho en-aut-sei=Seyama en-aut-mei=Kaho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumagaiYusuke en-aut-sei=Kumagai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeTadashi en-aut-sei=Abe en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchihashiTakayuki en-aut-sei=Uchihashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AndoToshio en-aut-sei=Ando en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakeiKohji en-aut-sei=Takei en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, College of Science and Engineering, Kanazawa University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, College of Science and Engineering, Kanazawa University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Physics, College of Science and Engineering, Kanazawa University kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=CREST, JST kn-affil= affil-num=10 en-affil=CREST, JST kn-affil= affil-num=11 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=EM kn-keyword=EM en-keyword=HS-AFM kn-keyword=HS-AFM en-keyword=amphiphysin kn-keyword=amphiphysin en-keyword=biophysics kn-keyword=biophysics en-keyword=cell biology kn-keyword=cell biology en-keyword=dynamin kn-keyword=dynamin en-keyword=human kn-keyword=human en-keyword=in vitro reconstitution kn-keyword=in vitro reconstitution en-keyword=membrane remodeling kn-keyword=membrane remodeling en-keyword=structural biology kn-keyword=structural biology END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=10 article-no= start-page=104508 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Correlation of superconductivity with crystal structure in (NH3)(y)CsxFeSe en-subtitle= kn-subtitle= en-abstract= kn-abstract= The superconducting transition temperature T-c of ammoniated metal-doped FeSe (NH3)(y)MxFeSe (M: metal atom) has been scaled with the FeSe plane spacing, and it has been suggested that the FeSe plane spacing depends on the location of metal atoms in (NH3)(y)MxFeSe crystals. Although the crystal structure of (NH3)(y)LixFeSe exhibiting a high T-c (similar to 44 K) was determined from neutron diffraction, the structure of (NH3)(y)MxFeSe exhibiting a low T-c (similar to 32 K) has not been determined thus far. Here, we determined the crystal structure of (NH3)(y)Cs0.4FeSe (T-c = 33 K) through the Rietveld refinement of the x-ray diffraction (XRD) pattern measured with synchrotron radiation at 30 K. The XRD pattern was analyzed based on two different models, on-center and off-center, under a space group of 14/mmm. In the on-center structure, the Cs occupies the 2a site and the N of NH3 may occupy either the 4c or 2b site, or both. In the off-center structure, the Cs may occupy either the 4c or 2b site, or both, while the N occupies the 2a site. Only an on-center structure model in which the Cs occupies the 2a and the N of NH3 occupies the 4c site provided reasonable results in the Rietveld analysis. Consequently, we concluded that (NH3)(y)Cs0.4FeSe can be assigned to the on-center structure, which produces a smaller FeSe plane spacing leading to the lower T-c. en-copyright= kn-copyright= en-aut-name=ZhengLu en-aut-sei=Zheng en-aut-mei=Lu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiaoXiao en-aut-sei=Miao en-aut-mei=Xiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaiYusuke en-aut-sei=Sakai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoHidenori en-aut-sei=Goto en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UesugiEri en-aut-sei=Uesugi en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EguchiRitsuko en-aut-sei=Eguchi en-aut-mei=Ritsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiyamaSaki en-aut-sei=Nishiyama en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoKunihisa en-aut-sei=Sugimoto en-aut-mei=Kunihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraAkihiko en-aut-sei=Fujiwara en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=2 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=3 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=4 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=5 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=6 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=7 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=8 en-affil=Japan Synchrotron Radiation Research Institute, SPring-8 kn-affil= affil-num=9 en-affil=Department of Nanotechnology for Sustainable Energy, Kwansei Gakuin University kn-affil= affil-num=10 en-affil=Research Centre of New Functional Materials for Energy Production, Storage and Transport, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=1 article-no= start-page=014502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preparation of new superconductors by metal doping of two-dimensional layered materials using ethylenediamine en-subtitle= kn-subtitle= en-abstract= kn-abstract= We have studied new superconductors prepared by metal doping of two-dimensional (2D) layered materials, FeSe and FeSe0.5Te0.5, using ethylenediamine (EDA). The superconducting transition temperatures (T(c)s) of metal-doped FeSe and metal-doped FeSe0.5Te0.5, i.e., (EDA)(y)MxFeSe and (EDA)(y)MxFeSe0.5Te0.5 (M: Li, Na, and K), were 31-45 K and 19-25 K, respectively. The stoichiometry of each sample was clarified by energy dispersive x-ray (EDX) spectroscopy, and the x-ray powder diffraction pattern indicated a large expansion of lattice constant c, indicating the cointercalation of metal atoms and EDA. The pressure dependence of superconductivity in (EDA)(y)NaxFeSe0.5Te0.5 has been investigated at a pressure of 0-0.8GPa, showing negative pressure dependence in the same manner as (NH3)(y)NaxFeSe0.5Te0.5. The T-c-c phase diagrams of MxFeSe and MxFeSe0.5Te0.5 were drawn afresh from the T-c and c of (EDA)(y)MxFeSe and (EDA)(y)MxFeSe0.5Te0.5, showing that the T-c increases with increasing c but that extreme expansion of c reverses the T-c trend. en-copyright= kn-copyright= en-aut-name=MiaoXiao en-aut-sei=Miao en-aut-mei=Xiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeraoTakahiro en-aut-sei=Terao en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangXiaofan en-aut-sei=Yang en-aut-mei=Xiaofan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiyamaSaki en-aut-sei=Nishiyama en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyazakiTakafumi en-aut-sei=Miyazaki en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoHidenori en-aut-sei=Goto en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwasaYoshihiro en-aut-sei=Iwasa en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Laboratory for Surface Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Applied Physics, The University of Tokyo kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=8 article-no= start-page=085109 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ce 4f electronic states of CeO1-xFxBiS2 studied by soft x-ray photoemission spectroscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract= We use soft x-ray photoemission spectroscopy (SXPES) to investigate Ce 4f electronic states of a new BiS2 layered superconductor CeO1-xFxBiS2, for polycrystalline and single-crystal samples. The Ce 3d spectrum of the single crystal of nominal composition x = 0.7 has no f(0) component and the spectral shape closely resembles the ones observed for Ce trivalent insulating compounds, strongly implying that the CeO layer is still in an insulating state even after the F doping. The Ce 3d-4f resonant SXPES for both polycrystalline and single-crystal samples shows that the prominent peak is located around 1 eV below the Fermi level (E-F) with negligible spectral intensity at EF. The F-concentration dependence of the valence band spectra for single crystals shows the increases of the degeneracy in energy levels and of the interaction between Ce 4f and S 3p states. These results give insight into the nature of the CeO1-xFx layer and the microscopic coexistence of magnetism and superconductivity in CeO1-xFxBiS2. en-copyright= kn-copyright=

pumping refers to the microwave-driven spin current injection from a ferromagnet into the adjacent target material. We theoretically investigate the spin pumping into superconductors by fully taking account of impurity spin-orbit scattering that is indispensable to describe diffusive spin transport with finite spin diffusion length. We calculate temperature dependence of the spin pumping signal and show that a pronounced coherence peak appears immediately below the superconducting transition temperature Tc, which survives even in the presence of the spin-orbit scattering. The phenomenon provides us with a new way of studying the dynamic spin susceptibility in a superconducting thin film. This is contrasted with the nuclear magnetic resonance technique used to study a bulk superconductor. en-copyright= kn-copyright= en-aut-name=InoueMasashi en-aut-sei=Inoue en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchiokaMasanori en-aut-sei=Ichioka en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AdachiHiroto en-aut-sei=Adachi en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=5 article-no= start-page=363 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sarcopenia and American Society of Anesthesiologists Physical Status in the Assessment of Outcomes of Hepatocellular Carcinoma Patients Undergoing Hepatectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sarcopenia following liver surgery has been reported as a predictor of poor prognosis. Here we investigated predictors of outcomes in patients with hepatocellular carcinoma (HCC) and attempted to establish a new comprehensive preoperative assessment protocol. We retrospectively analyzed the cases of 254 patients who underwent curative hepatectomy for HCC with Child-Pugh classification A at our hospital between January 2007 and December 2013. Sarcopenia was evaluated by computed tomography measurement. The influence of sarcopenia on outcomes was evaluated. We used multivariate analyses to assess the impact of prognostic factors associated with outcomes, including sarcopenia. Of the 254 patients, 118 (46.5%) met the criteria for sarcopenia, and 32 had an American Society of Anesthesiologists (ASA) physical status ≥3. The sarcopenic group had a significantly lower 5-year overall survival rate than the non-sarcopenic group (58.2% vs. 82.4% , p＝0.0002). In multivariate analyses of prognostic factors, sarcopenia was an independent predictor of poor survival (hazard ratio [HR]＝2.28, p＝0.002) and poor ASA status (HR＝3.17, p＝0.001). Sarcopenia and poor ASA status are independent preoperative predictors for poor outcomes after hepatectomy. The preoperative identification of sarcopenia and ASA status might enable the development of comprehensive approaches to assess surgical eligibility. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShinouraSusumu en-aut-sei=Shinoura en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NobuokaDaisuke en-aut-sei=Nobuoka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuiseTakashi en-aut-sei=Kuise en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeNobuyuki en-aut-sei=Watanabe en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=American Society of Anesthesiologists physical status kn-keyword=American Society of Anesthesiologists physical status en-keyword=hepatectomy kn-keyword=hepatectomy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=prognostic factor kn-keyword=prognostic factor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sound collection systems using a crowdsourcing approach to construct sound map based on subjective evaluation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a sound collection system that uses crowdsourcing to gather information for visualizing area characteristics.

We collected 693,582 samples of equivalent Aweighted loudness levels and their locations, and 5,935 samples of sounds and their locations. The data also include subjective evaluations by the participants. In addition, we analyzed the changes in sound properties of some areas before and after the opening of a large-scale shopping mall in a city. Next, we implemented visualizations on the server system to attract users’ interests. Finally, we published the system, which can receive sounds from any Android smartphone user.

However, a PAPʼs effect is limited in cases where articulation disorder is severe due to wide glossectomy and/or segmental mandibulectomy. In this paper, we describe speech outcomes of a patient with an articulation disorder following glossectomy and segmental mandibulectomy. We used a palatal plate (PP) based on a PAP, along with an artificial tongue (KAT). Speech improvement was evaluated by a standardized speech intelligibility test consisting of 100 syllables. The speech intelligibility score was significantly higher when the patient wore both the PP and KAT than when he wore neither (p＝0.013). The conversational intelligibility score was significantly improved with the PP and KAT than without PP and KAT (p＝0.024). These results suggest that speech function can be improved in patients with hard tissue defects with segmental mandibulectomy using both a PP and a KAT. The nature of the design of the PP and that of the KAT will allow these prostheses to address a wide range of tissue defects. en-copyright= kn-copyright= en-aut-name=KozakiKen-ichi en-aut-sei=Kozaki en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawakamiShigehisa en-aut-sei=Kawakami en-aut-mei=Shigehisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KonishiTakayuki en-aut-sei=Konishi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhtaKeiji en-aut-sei=Ohta en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanoJitsuro en-aut-sei=Yano en-aut-mei=Jitsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnodaTomoo en-aut-sei=Onoda en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MizukawaNobuyoshi en-aut-sei=Mizukawa en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AbeMasanobu en-aut-sei=Abe en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MinagiShogo en-aut-sei=Minagi en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=Okayama Dream Speech Project en-aut-sei=Okayama Dream Speech Project en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=4 en-affil=Dental Laboratory Division, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=13 en-affil=Department of Computer Science, Okayama University kn-affil= affil-num=14 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil= kn-affil= en-keyword=palatal augmentation prosthesis kn-keyword=palatal augmentation prosthesis en-keyword=artificial tongue kn-keyword=artificial tongue en-keyword=articulation disorder kn-keyword=articulation disorder en-keyword=glossectomy kn-keyword=glossectomy en-keyword=mandibulectomy kn-keyword=mandibulectomy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=390 end-page=395 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sound collection and visualization system enabled participatory and opportunistic sensing approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a sound collection system to visualize environmental sounds that are collected using a crowd-sourcing approach. An analysis of physical features is generally used to analyze sound properties; however, human beings not only analyze but also emotionally connect to sounds. If we want to visualize the sounds according to the characteristics of the listener, we need to collect not only the raw sound, but also the subjective feelings associated with them. For this purpose, we developed a sound collection system using a crowdsourcing approach to collect physical sounds, their statistics, and subjective evaluations simultaneously. We then conducted a sound collection experiment using the developed system on ten participants.We collected 6,257 samples of equivalent loudness levels and their locations, and 516 samples of sounds and their locations. Subjective evaluations by the participants are also included in the data. Next, we tried to visualize the sound on a map. The loudness levels are visualized as a color map and the sounds are visualized as icons which indicate the sound type. Finally, we conducted a discrimination experiment on the sound to implement a function of automatic conversion from sounds to appropriate icons. The classifier is trained on the basis of the GMM-UBM (Gaussian Mixture Model and Universal Background Model) method. Experimental results show that the F-measure is 0.52 and the AUC is 0.79. en-copyright= kn-copyright= en-aut-name=HaraSunao en-aut-sei=Hara en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeMasanobu en-aut-sei=Abe en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SoneharaNoboru en-aut-sei=Sonehara en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology Okayama University affil-num=3 en-affil= kn-affil=National Institute of Informatics END start-ver=1.4 cd-journal=joma no-vol=155 cd-vols= no-issue= article-no= start-page=79 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Changes in Physics Education at the Fachoberschule（ Vocationally-oriented Upper Secondary School） in Germany － Comparative Study between the Old and the New Textbook － kn-title=ドイツの専門上級学校における物理教育の変遷 －新旧教科書の比較考察－ en-subtitle= kn-subtitle= en-abstract= kn-abstract=　ドイツの職業教育諸学校の一つ，専門上級学校に焦点を当て，新旧物理教科書の比較考察に基づき，物理教育の変遷を明らかにしてきた。技師学校，高等専門学校の専門大学への昇格とともに，準備校として，職業上構学校などから創られてきた40年程度の伝統を有する専門上級学校用の新旧物理教科書において，物理教育の概念・構造が大きく異なっている。旧では，力ではじまり電気などを経て原子でおわるが，新では力と電気だけという範囲に違いがあること，重複（共通）している索引の割合は，旧では５％程度，新では30％程度であることなどは，学校の創生期（多様な生徒）からの隔りなどを経てきた，独自性の確立であり，また，単位系移行からの完了などが背景といえる。 en-copyright= kn-copyright= en-aut-name=TanakaKenji en-aut-sei=Tanaka en-aut-mei=Kenji kn-aut-name=田中賢二 kn-aut-sei=田中 kn-aut-mei=賢二 aut-affil-num=1 ORCID= en-aut-name=TanakaKeita en-aut-sei=Tanaka en-aut-mei=Keita kn-aut-name=田中啓太 kn-aut-sei=田中 kn-aut-mei=啓太 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系理科教育講座 affil-num=2 en-affil= kn-affil=津市立久居西中学校 en-keyword=ドイツ kn-keyword=ドイツ en-keyword=専門上級学校 kn-keyword=専門上級学校 en-keyword=物理教育 kn-keyword=物理教育 en-keyword=変遷 kn-keyword=変遷 en-keyword=教科書比較 kn-keyword=教科書比較 END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue= article-no= start-page=81 end-page=87 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Association Between Three-year Longitudinal Changes in Physical Strength in Children with Their Build, Health Habits, and Psychophysical Health Indexes. kn-title=３年間にわたる子どもの体力縦断的変化が形態,生活習慣,心身の健康指標におよぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study we examined the association between longitudinal changes in schoolchildren＇s physical strength with their build, health habits, and psychophysical health index scores. Students (n= 195) were followed for three years, from the fifth to the eighth grade. Setting as a baseline the students＇ results on the Ministry of Education, Culture, Sports, Science and Technology＇s new physical strength test, we extracted data on those students whose physical strength relatively improved (improved group: 28 boys, 53 girls) and on those whose strength relatively declined (declined group: 15 boys, 16 girls). Build, health habits, and psychophysical health index scores were compared between the two groups. It was found that, although there were no significant differences in eating habits or sleeping habits between the two groups, compared to the improved group, the declined group was more likely to be either obese or underweight, have short durations of intense exercise and total exercise, and longer duration of watching television or videos. The declined group also showed poorer psychological health status, such as lower self-efficacy and higher anxiety. 　These findings indicate that children with good exercise habits, such as consistently engaging in a adequate physical activities that include intense exercise, will have improved physical strength outcome over time, whereas those children with few regular exercise habits and whose strength will not improve over time, will show outcomes such as polarization of body weight (obesity and underweight tendencies) and poorer psychological health status. en-copyright=

kn-abstract=This paper develops an Intelligent Chair Tool (ICT) - a new chair-type human and machine interaction seating system powered by 36 intelligent pneumatic actuators. This tool can be used to facilitate investigation of chair shapes from spring and damping effects of seating and backrest surfaces. Each actuator used consists of five extensive elements of encoder, laser strip rod, pressure sensor, valves and PSoC microcontroller incorporated in a single device. By using the ICT, different shapes, spring and damping characteristics can be obtained to aid the design of chairs from the control inputs, i.e., position x, stiffness k(s) and viscous coefficient c.

P 2p core level study shows two bulk components, providing spectroscopic evidence for multiple chemical sites of doped-phosphorus atoms. This indicates that only a part of doped-phosphorus atoms contribute to the formation of carriers.

In resistivity measurements, the 13-nm-thick film exhibits a metal-insulator transition at around 290 K on cooling with change of three orders of magnitudes in resistivity. As the film thickness decreases, the metal-insulator transition broadens and the transition temperature increases. Below 4 nm, the films do not show the transition and become insulators. In situ SRPES measurements of near the Fermi level valence band find that the electronic state of the 2.5-nm-thick film is different than that of the temperature-induced insulator phase of VO2 itself although these two states are insulating. Ti 2p core-level photoemission measurements reveal that Ti ions exist near the interface between the films and TiO2 substrates, with a chemical state similar to that in (V,Ti)O-2 solid solution. These results indicate that insulating (V,Ti)O-2 solid solution is formed in the thinner films. We propose a simple growth model of a VO2 thin film on a TiO2(001) substrate. Near the interface, insulating (V,Ti) O-2 solid solution is formed due to the diffusion of Ti ions from the TiO2 substrate into the VO2 film. The concentration of Ti in (V,Ti) O-2 is relatively high near the interface and decreases toward the surface of the film. Beyond a certain film thickness (about 7 nm in the case of the present 13-nm-thick film), the VO2 thin film without any Ti ions starts to grow. Our work suggests that developing a technique for preparing the sharp interface between the VO2 thin films and TiO2 substrates is a key issue to study the physical property of an ultrathin film of "pure" VO2, especially to examine the presence of the novel electronic state called a semi-Dirac point phase predicted by calculations. en-copyright= kn-copyright= en-aut-name=MuraokaY. en-aut-sei=Muraoka en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaekiK. en-aut-sei=Saeki en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EguchiR. en-aut-sei=Eguchi en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakitaT. en-aut-sei=Wakita en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraiM. en-aut-sei=Hirai en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokoyaT. en-aut-sei=Yokoya en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShinS. en-aut-sei=Shin en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=6 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=RIKEN/SPring-8 END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=4 article-no= start-page=043916-1 end-page=043916-4 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100815 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bulk and surface physical properties of a CrO2 thin film prepared from a Cr8O21 precursor en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have prepared a CrO(2) thin film by chemical vapor deposition from a Cr(8)O(21) precursor and studied the bulk and surface physical properties.

The prepared film is found from x-ray diffraction analysis to be an (100)-oriented single phase. The magnetization and resistivity measurements indicate that the film is a ferromagnetic metal with a Curie temperature of about 400 K. Cr 3s core-level and valence band photoelectron spectroscopy spectra reveal the presence of a metallic CrO(2) in the surface region of the film.

Room temperature ferromagnetic behavior is observed in the magnetic hysteresis measurement. The sample shows a semiconductive temperature dependence in the resistivity measurement. Analysis of the Ti 2p(3/2) core-level XPS spectrum indicates that the titanium ions have a mixed valence of Ti(4+) and Ti(3+). In addition, the valence band spectrum reveals that the 3d electrons tend to localize on Ti(3+) ions in the hollandite-type TiO(2) lattice. Also, analysis of the valence band spectrum shows that the prepared sample is a wide-gap oxide with a band gap of 3.6 eV. These results indicate that the present hollandite-type K(x)Ti(8)O(16) sample can be classified as a TiO(2)-based wide-gap semiconductor with Curie temperature above room temperature. Room temperature ferromagnetism (RTFM) decreases in the sample prepared under a strong reducing gas atmosphere, accompanied with the decrease in the resistivity. The results imply that the localized 3d electrons are responsible for the RTFM of the K(x)Ti(8)O(16) sample. en-copyright= kn-copyright= en-aut-name=NoamiK. en-aut-sei=Noami en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MuraokaY. en-aut-sei=Muraoka en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakitaT. en-aut-sei=Wakita en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraiM. en-aut-sei=Hirai en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoY. en-aut-sei=Kato en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuroT. en-aut-sei=Muro en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamenoriY. en-aut-sei=Tamenori en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YokoyaT. en-aut-sei=Yokoya en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Faculty of Science, Research Laboratory for Surface Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Japan Synchrotron Radiation Research Institute (JASRI)/SPring-8 affil-num=6 en-affil= kn-affil=Japan Synchrotron Radiation Research Institute (JASRI)/SPring-8 affil-num=7 en-affil= kn-affil=Japan Synchrotron Radiation Research Institute (JASRI)/SPring-8 affil-num=8 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=5 article-no= start-page=582 end-page=584 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoemission study of electronic structure evolution across the metal-insulator transition of heavily B-doped diamond en-subtitle= kn-subtitle= en-abstract= kn-abstract=We studied the electronic structure evolution of heavily B-doped diamond films across the metal-insulator transition (MIT) using ultraviolet photoemission spectroscopy (UPS). From high-temperature UPS, through which electronic states near the Fermi level (E(F)) up to similar to 5k(B)T can be observed (k(B) is the Boltzmann constant and T the temperature), we observed the carrier concentration dependence of spectral shapes near E(F). Using another carrier concentration dependent UPS, we found that the change in energy position of sp-band of the diamond valence band, which corresponds to the shift of E(F), can be explained by the degenerate semiconductor model, indicating that the diamond valence band is responsible for the metallic states for samples with concentrations above MIT. We discuss a possible electronic structure evolution across MIT. en-copyright= kn-copyright= en-aut-name=OkazakiH. en-aut-sei=Okazaki en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ArakaneT. en-aut-sei=Arakane en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugawaraK. en-aut-sei=Sugawara en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoT. en-aut-sei=Sato en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiT. en-aut-sei=Takahashi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WakitaT. en-aut-sei=Wakita en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraiM. en-aut-sei=Hirai en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MuraokaY. en-aut-sei=Muraoka en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakanoY. en-aut-sei=Takano en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshiiS. en-aut-sei=Ishii en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IriyamaS. en-aut-sei=Iriyama en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawaradaH. en-aut-sei=Kawarada en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YokoyaT. en-aut-sei=Yokoya en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Department of Physics, Tohoku University affil-num=3 en-affil= kn-affil=WPI Research Center, Advanced Institute for Materials Research, Tohoku University affil-num=4 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=5 en-affil= kn-affil=Department of Physics, Tohoku University affil-num=6 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=8 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=9 en-affil= kn-affil=National Institute for Materials Science affil-num=10 en-affil= kn-affil=National Institute for Materials Science affil-num=11 en-affil= kn-affil=School of Science and Engineering, Waseda University affil-num=12 en-affil= kn-affil=School of Science and Engineering, Waseda University affil-num=13 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=12 article-no= start-page=124701-1 end-page=124701-4 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electronic Structure of the Novel Filled Skutterudite PrPt4Ge12 Superconductor en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have performed soft x-ray photoemission spectroscopy (SXPES) and resonant photoemission spectroscopy (RPES) of the filled skutterudite superconductor PrPt4Ge12 in order to study the electronic structure of valence band and the character of Pr 4f. SXPES of PrPt4Ge12 measured with 1200 eV photon energy, where spectral contribution of Pr 4f is negligible, was found nearly identical with that of LaPt4Ge12, indicating similarity of Pt–Ge derived electronic states of the two compounds. Good correspondence with band calculations allows us to ascribe the dominant Ge 4p character of the density of states at the Fermi level (EF). Pr 3d → 4f RPES shows that, although Pr 4f electrons in PrPt4Ge12 are not as strongly hybridized with conduction electrons near EF as in PrFe4P12, there are finite Pr 4f contribution to the states near EF in PrPt4Ge12. These PES results give the information of fundamental electronic structure for understanding the physical properties of the novel filled skutterudite superconductor PrPt4Ge12. en-copyright= kn-copyright= en-aut-name=NakamuraYoshiaki en-aut-sei=Nakamura en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkazakiHiroyuki en-aut-sei=Okazaki en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRikiya en-aut-sei=Yoshida en-aut-mei=Rikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakitaTakanori en-aut-sei=Wakita en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraiMasaaki en-aut-sei=Hirai en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeyaHiroyuki en-aut-sei=Takeya en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirataKazuto en-aut-sei=Hirata en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KumigashiraHiroshi en-aut-sei=Kumigashira en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OshimaMasaharu en-aut-sei=Oshima en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=6 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=National Institute for Materials Science (NIMS) affil-num=8 en-affil= kn-affil=National Institute for Materials Science (NIMS) affil-num=9 en-affil= kn-affil=CREST, Japan Science and Technology Corporation (JST) affil-num=10 en-affil= kn-affil=CREST, Japan Science and Technology Corporation (JST) affil-num=11 en-affil= kn-affil=The Graduate School of Science and Technology, Okayama University en-keyword=PrPt4Ge12 kn-keyword=PrPt4Ge12 en-keyword=filled skutterudite kn-keyword=filled skutterudite en-keyword=superconductor kn-keyword=superconductor en-keyword=soft x-ray photoemission spectroscopy kn-keyword=soft x-ray photoemission spectroscopy en-keyword=Pr 3d → 4f resonant photoemission kn-keyword=Pr 3d → 4f resonant photoemission en-keyword=electronic structure kn-keyword=electronic structure END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=1 article-no= start-page=014521-1 end-page=014521-5 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120726 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative photoemission studies on the superconducting gap of the filled skutterudite superconductors LaPt4Ge12 and PrPt4Ge12 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We performed a comparative study of the superconducting gap in the new filled skutterudite superconductors LaPt4Ge12 and PrPt4Ge12 using high-resolution photoemission spectroscopy.

The change of photoemission spectra is investigated across the hidden-ordertransition, and the emergence of a narrow band is clearly observed near the Fermi level for both (π,0) and (π,π) directions. In addition, it is shown that tuning of light's polarization allows the signal of a hole-like dispersive feature to enhance. These observations prove that laser angle-resolved photoemission spectroscopy is an effective tool for studying the evolution of electronic structures across the hidden-ordertransition in URu2Si2. en-copyright= kn-copyright= en-aut-name=YoshidaRikiya en-aut-sei=Yoshida en-aut-mei=Rikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraYoshiaki en-aut-sei=Nakamura en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuiMasaki en-aut-sei=Fukui en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagaYoshinori en-aut-sei=Haga en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoEtsuji en-aut-sei=Yamamoto en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ŌnukiYoshichika en-aut-sei=Ōnuki en-aut-mei=Yoshichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkawaMario en-aut-sei=Okawa en-aut-mei=Mario kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinShik en-aut-sei=Shin en-aut-mei=Shik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiraiMasaaki en-aut-sei=Hirai en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=5 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=6 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=7 en-affil= kn-affil=Institute for Solid State Physics, The University of Tokyo affil-num=8 en-affil= kn-affil=Institute for Solid State Physics, The University of Tokyo affil-num=9 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=10 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=11 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University en-keyword=Electronic structure kn-keyword=Electronic structure en-keyword=Laser angle-resolved photoemission spectroscopy kn-keyword=Laser angle-resolved photoemission spectroscopy en-keyword=URu2Si2 kn-keyword=URu2Si2 en-keyword=Hidden order kn-keyword=Hidden order END start-ver=1.4 cd-journal=joma no-vol=470 cd-vols= no-issue=S1 article-no= start-page=S389 end-page=S390 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis on photoemission spectrum of superconducting FeSe en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we present the result of soft X-ray photoemission spectroscopy and its comparison with the density functional calculation.

The observation of a narrow dispersive band near the Fermi level in the ordered state as well as its absence in a Rh-substituted sample strongly suggest that the emergence of the narrow band is a clear signature of the hidden-order transition. The temperature dependence of the narrow band, which appears at the onset of the hidden-order transition, invokes the occurrence of periodicity modification in the ordered state, which is shown for the first time by any spectroscopic probe. We compare our data to other previous studies and discuss possible implications. en-copyright= kn-copyright= en-aut-name=YoshidaRikiya en-aut-sei=Yoshida en-aut-mei=Rikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraYoshiaki en-aut-sei=Nakamura en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuiMasaki en-aut-sei=Fukui en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagaYoshinori en-aut-sei=Haga en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoEtsuji en-aut-sei=Yamamoto en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnukiYoshichika en-aut-sei=Onuki en-aut-mei=Yoshichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkawaMario en-aut-sei=Okawa en-aut-mei=Mario kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinShik en-aut-sei=Shin en-aut-mei=Shik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiraiMasaaki en-aut-sei=Hirai en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=5 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=6 en-affil= kn-affil=Advanced Science Research Center, Japan Atomic Energy Agency affil-num=7 en-affil= kn-affil=Institute for Solid State Physics, The University of Tokyo affil-num=8 en-affil= kn-affil=Institute for Solid State Physics, The University of Tokyo affil-num=9 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=10 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=11 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=19 article-no= start-page=195114-1 end-page=195114-5 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electronic structure of pristine and K-doped solid picene: Nonrigid band change and its implication for electron-intramolecular-vibration interaction en-subtitle= kn-subtitle= en-abstract= kn-abstract=We use photoemission spectroscopy to study electronic structures of pristine and K-doped solid picene. The valence band spectrum of pristine picene consists of three main features with no state at the Fermi level (EF) while that of K-doped picene has three structures similar to those of pristine picene with new states near EF, consistent with the semiconductor-metal transition. The K-induced change cannot be explained with a simple rigid-band model of pristine picene but can be interpreted by molecular-orbital calculations considering electron-intramolecular-vibration interaction.

In this study, the five extrinsic proteins were purified from alkaline Tris extracts of the diatom PSII by anion and cation exchange chromatographic columns at different pH values. Reconstitution experiments in various combinations with the purified extrinsic proteins showed that PsbO, PsbQ′, and Psb31 rebound directly to PSII in the absence of other extrinsic proteins, indicating that these extrinsic proteins have their own binding sites in PSII intrinsic proteins. On the other hand, PsbV and PsbU scarcely rebound to PSII alone, and their effective bindings required the presence of all of the other extrinsic proteins. Interestingly, PSII reconstituted with Psb31 alone considerably restored the oxygen evolving activity in the absence of PsbO, indicating that Psb31 serves as a substitute in part for PsbO in supporting oxygen evolution. A significant difference found between PSIIs reconstituted with Psb31 and with PsbO is that the oxygen evolving activity of the former is scarcely stimulated by Cl− and Ca2+ ions but that of the latter is largely stimulated by these ions, although rebinding of PsbV and PsbU activated oxygen evolution in the absence of Cl− and Ca2+ ions in both the former and latter PSIIs. Based on these results, we proposed a model for the association of the five extrinsic proteins with intrinsic proteins in diatom PSII and compared it with those in PSIIs from the other organisms.

dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Artificial Lighting by Fluorescent Lamps Part I. Fundamental Study On the quantitative comparison of fluorescent lamps with incandescent lamps kn-title=螢光放電燈による人工照明 基礎編I 螢光放電燈と白熱電球との量的比較に就て en-subtitle= kn-subtitle= en-abstract= kn-abstract=The fluorescent lamp, a new light-source which is called the "ideal light", was experimentally compared with the incandescent lamp on the quantitative basis, and the undermentioned conclusions were obtained. (1) In Lange's Standard-Beleuchtungsmesser, the photoelectric current is accurately proportional to the intensity of illumination, and the error is within a range of about 5% as checked with the Hefner's lamp, proving that it is an excellent photo-cell illuminometer. (2) In photometry, if there is a space more than double the length of mojor axis, the error is slight even though the inverse square law is applied. (3) The green fluorescent lamp is the highest in luminous intensity and lamp efficiency, which values lessen in order of the white fluorescent lamp, daylight fluorescent lamp, blue-white fluorescent lamp, pink fluorescent lamp and blue fluorescent lamp. (4) The comparison between the value of luminous intensity as measured by Bechstein's Flimmerphotometer and the values obtained by photometers of other types proves the following: (a) The error is generally small in Weber's photometer, but in case of green, blue-white or blue light, which differs in color of light, the measurement of R-G is impracticable. (b) The error in Bechstein's Luxmeter is less than 5% in any colors of light except green. However, in measurement of different colors other than the so-called "white", there is a trend that the judgement of equilibrium is apt to accompany difficulties. (c) Errors in Tavolux are rather great, but this is considered to be due to the variation caused by age. (d) In Lange's Standard-Beleuchtungsmesser, the error is small in case of white lights, but is fairly great in case of heterochromatic lights. Generally it is difficult to make the physical eye perfectly in accord with the international standard visibility curve, hence there is the need to obtain the light-meter correction factors with respective photometers. (5) Brightness is extremely small in fluorescent lamps, being 0.46c/c㎡ for the white fluorescent lamp, and 0.37c/c㎡ for the daylight fluorescent lamp, or so small as 1/70 of the 100W frosted incandescent lamp, whereas the lamp efficiency is so high as 5～7 times the incandescent lamp. (6) The bulb-wall temperature of a fluorescent lamp is very low, while its heat radiation is small. It is a so-called cool light. (7) It is desirable to light a fluorescent lamp at an ambient temperature within the range of 10°～30°C. The maximum luminous intensity is attained at the temperature of 20°～21°C. (8) In photometric measurement of a fluorescent lamp, it must be carried out after the lapse of more than 10 minutes from the time when the lamp is lit first. (9) One-fifths of both end-parts of a fluorescent lamp are darker by about 30% as compared with other parts of the lamp. (10) In the horizontal illumination curve of fluorescent lamp, there is witnessed a peculiar refraction at the horizontal distance of 50cm rigth beneath the light-source. (11) When measuring the luminous intensity and illumination, the location and direction of light-source must always be kept constant. (12) The variation in luminous intensity for every 1% of the change in the voltage of light-source is 1.8% with the fluorescent lamp, and such variations are lineal as shown in graph. In the incandescent lamp, the variation in luminous intensity grows large in proportion to the rise in voltage, and keep the relations between each other which are represented by a curve. The variations in intensity of illumination within any given time-unit are far less in frequency and degree compared with the incandescent lamp, and are less affected by the fluctuations in the voltage of the source of electric supply. en-copyright= kn-copyright= en-aut-name=NaruseRyujo en-aut-sei=Naruse en-aut-mei=Ryujo kn-aut-name=成瀬龍城 kn-aut-sei=成瀬 kn-aut-mei=龍城 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学教室 END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=97 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A kinesthetic-based collaborative learning system for distributed algorithms en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we present a learning support system DASE-E to help students understand fundamental concepts of distributed algorithms in computer science. DASE-E is a collaborative learning system, in which the task of students is to devise a distributed algorithm. DASE-E offers a set of small wireless terminals with accelerometers. Each student plays the role of a process with a terminal, according to the algorithm that students devised. Each terminal enables a student to take physical actions that control the behavior of a process in the simulator. After the role playing simulation is finished, students discuss their activity played back on a screen. We implemented the system for learning distributed leader election algorithms, had a trial exercise in our research group, and we confirmed that it is effective to learn the critical part of distributed systems and algorithms. en-copyright= kn-copyright= en-aut-name=NagatakiHiroyuki en-aut-sei=Nagataki en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiTaichi en-aut-sei=Fujii en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiYukiko en-aut-sei=Yamauchi en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakugawaHirotsugu en-aut-sei=Kakugawa en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasuzawaToshimitsu en-aut-sei=Masuzawa en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Center for Faculty Development, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Information Science and Technology, Osaka University affil-num=3 en-affil= kn-affil=Graduate School of Information Science, Nara Institute of Science and Technology affil-num=4 en-affil= kn-affil=Graduate School of Information Science and Technology, Osaka University affil-num=5 en-affil= kn-affil=Graduate School of Information Science and Technology, Osaka University en-keyword=computer science education kn-keyword=computer science education en-keyword=distributed algorithm kn-keyword=distributed algorithm en-keyword=collaborative learning kn-keyword=collaborative learning en-keyword=kinesthetic learning activity kn-keyword=kinesthetic learning activity en-keyword=algorithm visualization kn-keyword=algorithm visualization END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=2 article-no= start-page=143 end-page=160 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An Institutionalist Approach to Liberaliam (1) kn-title=自由主義に対する制度派的アプローチ(1) en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this paper is to present a new way of theorizing liberalist political / social doctrines. Formerly, most supporters of liberalism have constructed their political / social theories on the base of "methodological individualism". But here I try to found a discriptive / normative theory of liberal societies on the ground ofa sort of "wholism". A main idea of this paper is to conceptualize "personhood" as one type of institutions. I define "institution" as a expected pattern of actions, or a system of rules of conducts, and see "person" as the special type of institution, the institution enacted by one physical humane individual. And I make a thoretical modell of liberal society as a band of different types of institutions. In this modell, "person" is not a sort of "social atom", but have a very specific functioning. en-copyright= kn-copyright= en-aut-name=InabaShin-ichiro en-aut-sei=Inaba en-aut-mei=Shin-ichiro kn-aut-name=稲葉振一郎 kn-aut-sei=稲葉 kn-aut-mei=振一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=6-1 article-no= start-page=2963 end-page=2966 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=19590501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Consideration on the New Patients Attacked By So Called Secondary Epidemic of Infectious Hepatitis kn-title=流行性肝炎の所謂第二次流行における新患者に就ての検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1. The new patients of so called secondary epidemy of infectaous hepatitis were chiefly those who had been listed as the patients of latent hepatitis or inapparent infection in the previous epidemy. 2. In fairly great number of cases in which the patients were listed as inapparent infection, patients complained trifling subjective symptoms and later they were suspected as of slight abortive form. In the cases of compiaining subjective symptoms as well as in the cases of having no complaint, the percentage of onset was approximately the same. In case of infectious hepatitis, it is considered that the germs may have same slight responsive effect upon the patient after infected, or sometimes may have no effect for considerablly long time, but as the physical strength declines, the germs show their special quality of causing the apparent symptoms. en-copyright= kn-copyright= en-aut-name=KosakaKiyowo en-aut-sei=Kosaka en-aut-mei=Kiyowo kn-aut-name=小坂淳夫 kn-aut-sei=小坂 kn-aut-mei=淳夫 aut-affil-num=1 ORCID= en-aut-name=SetoKeitaro en-aut-sei=Seto en-aut-mei=Keitaro kn-aut-name=瀬戸桂太郎 kn-aut-sei=瀬戸 kn-aut-mei=桂太郎 aut-affil-num=2 ORCID= en-aut-name=NagashimaHideo en-aut-sei=Nagashima en-aut-mei=Hideo kn-aut-name=長島秀夫 kn-aut-sei=長島 kn-aut-mei=秀夫 aut-affil-num=3 ORCID= en-aut-name=IwaharaMasao en-aut-sei=Iwahara en-aut-mei=Masao kn-aut-name=岩原正雄 kn-aut-sei=岩原 kn-aut-mei=正雄 aut-affil-num=4 ORCID= en-aut-name=IshidaTatsuo en-aut-sei=Ishida en-aut-mei=Tatsuo kn-aut-name=石田立夫 kn-aut-sei=石田 kn-aut-mei=立夫 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=5 en-affil= kn-affil=岡山県衛生部公衆衛生課 END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=5-6 article-no= start-page=423 end-page=435 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Detection of human sequence related to the squirrel monkey retrovirus kn-title=ヒトゲノムDNA中のリスザルレトロウイルス関連遺伝子の検出 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Squirrel monkey retrovirus (SMRV) is an endogenous type D retrovirus of the squirrel monkey, a New World primate. Southern hybridization with cloned SMRV-H revealed that 3040 copies of SMRV proviral DNA are present in the squirrel monkey genome and the majority have almost the same physical map as that of the cloned SMRV-H. SMRV-related sequences in the human genome were sought using the same method with various cloned SMRV-H DNA fragments under conditions of relaxed stringency. The discrete restriction fragments were frequently detected in the DNA from normal humans with the LTR and parts of gag and env as probes. Since SMRV LTR has very little homology with the LTRs of other retroviruses, the fragments detected with the LTR probe were characterized as SMRV-related human sequences. SMRV LTR-related sequences were also detected in the African green monkey and chicken, but not in the salmon, mouse, or dog. In conclusion, SMRV-related sequences are present in human DNA, and some of them might represent endogenous retroviral sequences of human DNA. en-copyright= kn-copyright= en-aut-name=AsonumaHirohiko en-aut-sei=Asonuma en-aut-mei=Hirohiko kn-aut-name=阿曽沼裕彦 kn-aut-sei=阿曽沼 kn-aut-mei=裕彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部癌源研究施設生化学部門 en-keyword=ヒトDNA kn-keyword=ヒトDNA en-keyword=内在性レトロウイルス kn-keyword=内在性レトロウイルス en-keyword=リスザルレトロウイルス kn-keyword=リスザルレトロウイルス en-keyword=サザンハイブリダイゼーション kn-keyword=サザンハイブリダイゼーション END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=1-2 article-no= start-page=167 end-page=174 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on urinary protein after physical load Report 3.

The correlation between the concentration of urinary protein using CBB colorimetry and that using our staining method on agar plate was determined. 1. Assay procedure 1.5g of agar was disselved 90ml of water while waring at 60°C (solution A) 0.005g CBB was disselved into 5ml of water (solution B) solution A and solution B and were mixed and wate was added to a final volume of 100ml. For urinary protein determination, 15μl of urine were spotted on agar plate. After 15 minutes, colored spots were evaluated. For the semiquantitative determination, the plate was dried at 37°C for 30 minutes and spots were compared wdth a standard spot using the naked eye. For the quantitative determination, the plate was dried at 37°C for 30 minutes and spots were analyzed with a densitometer. 2. The newly devised CBB method is convenient for micro assay of urinary protein. The urine samples can be determined in small amounts and the method is simple highly sensitive and highly accurate. Many urine specimens can be measured in a field survey. Result can be stored for long periods of time after blotting into writing menbrane-filter. 3.

We classified 89 cases of rheumatoid arthritis and arthrosis deformans according to Prof. T. Kodama's criteria as follows: 33 cases of (222) polyarthritis systemica (37%), 15 cases of (221) polyarthritis non systemica (16.8%) 22 cases of (111) monoarthrosis non systemica (24%), and others. 2. We analysed their symptoms following the criteria recommended by the New York Rheumatism Association and Prof. T. Kodama. In many cases of (222), their local and general symptoms were found to belong to Class III or IV, and in many cases of (111) and (221), to Class I or II. This shows that (222), here treated, was severer than (111) and (221) in both local and general conditions. The hepatic disorder and anemia were found to occur in patients with (222). 3. We treated these 89 cases chiefly by spa therapy and intraarticular injection of hydrocortisune, and evaluated the results by the criteria recommended by N. Y. R. A. and Prot. T. Kodama. Each of these treatments was more effective on (111), (121), and (221) than on (222). In all cases, the combined treatment with the said two measures was more efficacious than the separate treatment with each of the two. 4. The effects of the intraarticular hydrocortisone injections, 686 in total and mostly into knee joints, were examined. The most efficacious of these were obtained when the injection was made into fingers, toes or hip joints. In our experiences, the post-injection flare ups and the adverse effects of the treatments were observed in 2.8% of the cases treated, but they lasted only for a few days. 5. Of five cases of (222), where the combined treatment of hydrocortisone intraarticular injection and spa therapy was given for 5-14 months, detailed descriptions are given. By this treatment the physical abilities in joints of patients were improved remarkably and their general conditions were ameliorated gradually without any adverse effects. en-copyright= kn-copyright= en-aut-name=NakaharaYasuhiro en-aut-sei=Nakahara en-aut-mei=Yasuhiro kn-aut-name=仲原泰博 kn-aut-sei=仲原 kn-aut-mei=泰博 aut-affil-num=1 ORCID= en-aut-name=IzumiTomokuni en-aut-sei=Izumi en-aut-mei=Tomokuni kn-aut-name=泉友圀 kn-aut-sei=泉 kn-aut-mei=友圀 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所外科 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所外科 END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue= article-no= start-page=38 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=1961 dt-pub=19610625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CHEMICAL STUDY ON SEKIGANE HOT SPRINGS, TOTTORI-KEN kn-title=関金温泉地の調査研究水温および化学成分について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The chemical and physical characteristics of the thermal and ground waters in Sekigane Hot Springs were determined. The content of the following chemical constituents was determined: Cl(-), S0(4)(2-), HCO(3)(-), Ca(2+), As, F, U and Ra. The relationship between water temperature and depth of spring wens was found to be indicative of the presence of a fissure, in agreement with the conclusion reached geologically by Sugiyama. The water temperature, the e1ectricconductivity and the content of chemical constituents of the ground water were as expected markedly lower than those of the thermal water. As a whole, however, the water temperature, the electricconductivity and the content of SO(4)(2-), HCO(3)(-), Ca(2+), As and F are in positive and linear correlation with the Cl- content. In other words, these characteristics of the waters, excluding the U and Ra content, correlate positively and linearly with each other. This was interpreted to mean that a thermal water of high salinity is simply diluted by a cold ground water of very low salinity, and that a ground water of relatively high salinity is contaminated by thermal water. The content of U and Ra of these spring waters is lower than that of the spring waters in Ikeda, Shimane-ken, and Misasa, Tottori-ken, where radioactive springs also issue. Finally, it is concluded that As and F will be as useful as Cl- in chemically locating a new site for a spring well in Sekigane because of the low contamination due to human life of ground water by these elements. en-copyright= kn-copyright= en-aut-name=SakanoueMasanobu en-aut-sei=Sakanoue en-aut-mei=Masanobu kn-aut-name=阪上正信 kn-aut-sei=阪上 kn-aut-mei=正信 aut-affil-num=1 ORCID= en-aut-name=MifuneMasaaki en-aut-sei=Mifune en-aut-mei=Masaaki kn-aut-name=御船政明 kn-aut-sei=御船 kn-aut-mei=政明 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所化学部門 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所化学部門 END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=2 article-no= start-page=119 end-page=124 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Psycho-oncology ： An overview kn-title=精神腫瘍学概論 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=UchitomiYosuke en-aut-sei=Uchitomi en-aut-mei=Yosuke kn-aut-name=内富庸介 kn-aut-sei=内富 kn-aut-mei=庸介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　精神神経病態学 en-keyword=がん kn-keyword=がん en-keyword=サイコオンコロジー kn-keyword=サイコオンコロジー en-keyword=quality of life kn-keyword=quality of life en-keyword=緩和ケア kn-keyword=緩和ケア END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=5 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20063 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Search for anomalous couplings in top decay at hadron colliders en-subtitle= kn-subtitle= en-abstract= kn-abstract=

We present a quantitative study on sensitivities to the top-decay anomalous couplings, taking into account realistic experimental conditions expected at Tevatron and LHC. A double angular distribution of W and charged lepton in the top-decay is analyzed, using t<(t)<($)over bar> events in the leptons+jets channel. In order to improve sensitivities to the anomalous couplings, we apply two techniques: (i) We use a likelihood fitting method for full kinematical reconstruction of each top event. (ii) We develop a new effective spin reconstruction method for leptonically-decayed top quarks; this method does not require spin information of the antitop side. For simplicity, we neglect couplings of right-handed bottom quark as well as CP violating couplings. The 95% C.L. estimated bound on a ratio of anomalous couplings reads -0.81 < f(2)/f(1)<-0.70, -0.12 < f(2)/f(1)< 0.14 using 1000 reconstructed top events at Tevatron, while -0.74 < f(2)/f(1)<-0.72, -0.01 < f(2)/f(1)< 0.01 is expected with 100 k reconstructed top events at LHC, where only statistical errors are taken into account. A two-fold ambiguity in the allowed range remains when the number of events exceeds a few hundred.

Ambipolar field-effect transistor (FET) devices were fabricated with a heterostructure of C60 and pentacene, and their p- and n-channel field-effect mobilities were studied as a function of thickness of pentacene thin-films. The observed dependences of the μ values were interpreted in terms of the morphology of the thin films and the band structure of C60/pentacene heterostructure. A complementary metal-oxide-semiconductor (CMOS) circuit was fabricated by integration of two ambipolar FETs, aiming at realization of a new CMOS inverter circuit composed of FETs with the same device structure. The gain of 4, the threshold voltage of 85 V, and the complex output characteristics were explained on the basis of the properties of the component FET devices.

A new material of higher fullerene, RbxC84, was synthesized by intercalating Rb metal into C-84 crystals. The RbxC(84) crystals showed a simple cubic (sc) structure with lattice constant, a, of 16.82 (2) angstrom at 6.5 K, and 16.87 (2) angstrom at 295 K. The Rietveld refinements were achieved with the space group, Pa (3) over bar, based on a model that the C-2 axis of D2d-C84 aligned along [111]. The sample composition was determined to be Rb-8.8(7) C-84. The ESR spectrum at 303 K was composed of a broad peak with peak-to-peak linewidth Delta H-pp of 220 G, and a narrow peak with Delta H-pp of 24 G. Temperature dependence of the broad peak clearly showed a metallic behavior. The metallic behavior was discussed based on a theoretical calculation. This finding of new metallic phase in a higher fullerene is the first step for a development of new types of fullerene materials with novel physical properties such as superconductivity.

A new chelating resin using chitosan as a base material was synthesized. Functional moiety of 2-amino-5-hydroxy benzoic acid (AHBA) was chemically bonded to the amino group of cross-linked chitosan (CCTS) through the arm of chloromethyloxirane (CCTS-AHBA resin). Several elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and rare earth elements (REEs), could be adsorbed on the resin. To use the resin for on-line pretreatment, the resin was packed in a mini-column and installed into a sequential-injection/automated pretreatment system (Auto-Pret System) coupled with inductively coupled plasma-atomic emission spectrometry (ICP-AES). The sequential-injection/automated pretreatment system was a laboratory-assembled, and the program was written using Visual Basic software. This system can provide easy operation procedures, less reagent consumption, as well as less waste production. Experimental variables considered as effective factors in the improvement sensitivity, such as an eluent concentration, a sample and an eluent flow rate, pH of samples, and air-sandwiched eluent were carefully optimized. The proposed system provides excellent on-line collection efficiency, as well as high concentration factors of analytes in water samples, which results in highly sensitive detection of ultra-trace and trace analysis. Under the optimal conditions, the detection limits of 24 elements examined are in the range from ppt to sub-ppb levels. The proposed method was validated by using the standard reference material of a river water, SLRS-4, and the applicability was further demonstrated to the on-line collection/concentration of trace elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and REEs in water samples.

The influences of emotional changes induced by being exposed to a new environment on the pharmacokinetics of plasma drug concentration were studied in male Wistar rats. Transfer from a familiar home cage to a new home cage was considered to induce psychological (non-physical) emotional changes. First, nicorandil and zonisamide, drugs that act on the peripheral system and central nervous systems, were used, respectively. Immediately after oral administration of nicorandil (10 mg/kg) or zonisamide (50 mg/kg), the animals were transferred to new home cages. Plasma nicorandil and zonisamide concentrations were determined by high-performance liquid chromatography at 1 and 4 h after administration. Plasma nicorandil concentration in the group transferred to new home cages was significantly decreased relative to levels in the non-transferred control group. However, zonisamide concentrations were unchanged. These findings suggest that the pharmacokinetics of nicorandil, but not those of zonisamide, tend to be influenced by non-physically induced emotional changes.

Blood cells of schizophrenics differ in many points from those of normal subjects. First of all the shape of them is flat and thin. This tendency is more marked in old group than in new group; the volume is small; flat corpuscles are more numerous in them in the normal; and the blood resistance against diluted saline solution is stronger than that of the normal. It has long since been known that the rate of corpuscle sedimentation is being accelerated in schizophrenics. A simple physical cause that blood corpuscles are flat and numerous can explain this phenomenon. It is said that there is an antisphering substance among the factors controlling the thickness and roundness of blood corpuscles. Yet it has not been determined whether this substance on the surface of the blood of schizophrenics is large or small. Blood corpuscles are said to lose their peculiar disc-shape and to be completely destroyed at the pH of 9.2 when the antisphering substance is removed from the surface of blood corpuscles. The lower the pH is the better is the absorption of this substance on the surface of blood corpuscles; and it seems that the more this substance attaches itself to blood corpuscles the greater is the degree of flatness and in this connection it is interesting to note that the pH of schizophrenic blood is low in low in general. On the other hand, however, sphericity is increased at the time when the acidity of blood is increased due to a sudden movement of acidic substances immediately after ECT. Again in the case of coma of insulin treatment, blood tends to be alkaline and even then an increase in the sphericity of corpuscles is indicated. Consequently it seems tnat the roundness of blood corpuscles is not solely dependent upon antisphering substance and pH.

Considering that there is no pump feeding an Electro-Rheological-Fluid, a new type of pump has been manufactured and fluid dynamic characteristics have been elucidated. This pump can feed the ERF by utilizing effectively the change in physical properties of the fluid by the application of voltage. The principle and configuration of this pump and the methods of theoretical analysis are described, and the influence of the voltage on the feeding characteristics was examined The dispersoidal ERF has been treated hitherto as a type of Newtonian fluid. However. experiments showed that not only the induced shear stress but also the viscosity is affected by the electric field strength and that the ERF must be treated as a pseudo-plastic flow. The method of analysis described here can be applied to design the pump differing in dimensions because the analysis gave qualitative evaluations about the flow rate and pressure difference

Such cases as organic diseases, apparent schizophrenia and depression were excluded. The author could classify them into 5 groups. The 1st group is neurotic cases. The 2nd group is schizophrenic cases shifted from so-called borderline cases. The 3rd group is the cases of paranoid reaction. The 4th group is borderline cases in adolescence. The last 5th group is the cases unable to be classified into any groups above mentioned, and shows most characteristic symptoms. The distinguishing traits of 5th group were as follows. They developed symptoms in middle ages after being affected psychologically or physically. The persistent abnormal cenesthesia full of agony was rather tinged with hallucination, and it was some experience of moving, tense or pulling sensations, or of utterly new strange foreign sensations. Despite the peculiar strange complaints, they did not make pathological interpretations and their insight into their morbid states was preserved to some extent. But, pathological obsessive attitudes (such as skin-rubbing) and temporary abulic states often appeared, so that in their course they wore temporarily psychotic feature. Despite the chronic course, schizophrenic tendency did not appear. The author discussed the psychopathology of cenesthopathy and concluded that the 5th group should be diagnosed as typical cenesthopathia. en-copyright= kn-copyright= en-aut-name=ShimoyamaAtsushi en-aut-sei=Shimoyama en-aut-mei=Atsushi kn-aut-name=下山敦士 kn-aut-sei=下山 kn-aut-mei=敦士 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=5-6 article-no= start-page=641 end-page=649 dt-received= dt-revised= dt-accepted= dt-pub-year=1984 dt-pub=19840430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on determination of urinary protein Part Ⅳ.

There are two ways, the Donaggio reaction and ASPRO method (a new acid soluble glycoprotein assay using coomassie brilliant blue G-250), to measure glycoprotein and other acid soluble protein for estimating the physical load. This investigation was performed to identify the composition of protein detected by the Donaggio reaction (DRPSu) and of perchloric acid soluble protein detected by the ASPRO method in urine (ASPROu). In DRPSu, albumin, α1-acidglycoprotein, α2-HS-glycoprotein, Zn-α2-glycoprotein, α1-antitrypsin, α1-antichymotrypsin and transferrin were recognized by double diffusion, single radial immunodiffusion and immunoelectrophoresis. In ASPROu, the same proteins as above were recognized according to the same immunological methods. However, a different ratio of protein components was recognized between DRPSu and ASPROu by SDS-PAGE. The perchloric acid soluble protein in urine before and after exercise from high school boys was measured by the ASPRO method, and a significant difference was recognized between before and after exercise. en-copyright= kn-copyright= en-aut-name=TanakaYukiko en-aut-sei=Tanaka en-aut-mei=Yukiko kn-aut-name=田中由紀子 kn-aut-sei=田中 kn-aut-mei=由紀子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 en-keyword=Donaggio 反応陽性物 kn-keyword=Donaggio 反応陽性物 en-keyword=urinary protein kn-keyword=urinary protein en-keyword=ASPRO法 kn-keyword=ASPRO法 en-keyword=SDS-PAGE kn-keyword=SDS-PAGE END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=3-4 article-no= start-page=335 end-page=345 dt-received= dt-revised= dt-accepted= dt-pub-year=1983 dt-pub=19830430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the determination of urinary protein part III.

Five μl of the urine to be measured is dropped on the 2cm(2) filter paper, and dried at room temperature. The paper is immersed in a mixture of ethanol, acetic acid and distillated water (35:10:55) which contains 0.2% Coomassie Brilliant Blue R-250 (CBB), and washed with water until the waste water becomes colorless. The paper is again immersed into a mixture but without CBB, after which the paper is rinsed with water again. The protein concentration in the urine sample is determined by comparing the hue of the urine spot with a standard violet hue chart, as well as by the color intensity of the extract of the spot with 3% hydrogen chloride in ethanol at 595 nm by spectrophotometry. This method was applied to the determination of protein in urine from junior college girls immediatly after arriving at school and after cooking study, from adults in a factory at the time of their regular medical examination, and from high school boys before and after physical exercise. The results were compared with that of the TONEIN-TP method. With the SPOTCBB-DYE method, samples can be kept as colored spots on the filter paper, and the protein in urine can be preserved as a spot on the filter paper and measured at any time. en-copyright= kn-copyright= en-aut-name=TanakaYukiko en-aut-sei=Tanaka en-aut-mei=Yukiko kn-aut-name=田中由紀子 kn-aut-sei=田中 kn-aut-mei=由紀子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 en-keyword=Coomassie Brilliant Blue R-250 kn-keyword=Coomassie Brilliant Blue R-250 en-keyword=urinary protein kn-keyword=urinary protein en-keyword=沪紙Spot-CBB染色法 kn-keyword=沪紙Spot-CBB染色法 END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=3-4 article-no= start-page=341 end-page=349 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=1988 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation of new exocrine pancreatic function tests and their application to clinical research 2.

Patients were randomly divided into the following two groups: nine patients into the control group (continuance of spa-bathing) and 16 patients into the spa-drink therapy group (continuance of spa-bathing plus commencement of spa-drink therapy). Spa-drink therapy refers to drinking 200ml of warm spa-water (40℃) two times a day between meals, in the morning and in the afternoon. Exocrine pancreatic function was evaluated by: fecal chymotrypsin activity (FCA), which was determined by a new colorimetric method with Monotest Chymotrypsin supplied by Boehringer Mannheim; and cumulative % PABA recovery in 6-hour urine, which was determined with N-BT-PABA supplied by Eisai.The 2-week spa-drink therapy significantly improved the FCA value in four of the 16 patients (25%) while none of the controls showed a significant improvement in the FCA value. The 2-week spa-drink therapy significantly improved the PFD value in seven of the 16 patients (43.8%), while only 11.1% of the controls showed an improvement. These improvements with the spa-drink therapy were probably due to an enhancement of exocrine pancreatic secretion in four patients, and an improvement of gastric secretory or motor function in three patients. With 4 weeks of spa-drink therapy, however, these improvements tended to become less prominent, with FCA and PFD approaching the pre-treatment values.The 2-week spa-drink therapy improved the digestive function in some individuals either by enhancing exocrine pancreatic function or by improving the gastric secretory or motor function. However, the effect became less prominent thereafter, a phenomenon known as "adaptation" in the field of balneotherapy. en-copyright= kn-copyright= en-aut-name=MatsumotoShuji en-aut-sei=Matsumoto en-aut-mei=Shuji kn-aut-name=松本秀次 kn-aut-sei=松本 kn-aut-mei=秀次 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属環境病態研究施設成人病学分野 en-keyword=spa-drink therapy kn-keyword=spa-drink therapy en-keyword=pancreatic exocrine function kn-keyword=pancreatic exocrine function en-keyword=fecal chymotrypsin activity kn-keyword=fecal chymotrypsin activity en-keyword=PFD test kn-keyword=PFD test END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=2 article-no= start-page=55 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New Approach to Short-Range Ordering in GP(2) Zones in Al-3.82wt. % Cu Alloy en-subtitle= kn-subtitle= en-abstract= kn-abstract=X-ray diffuse scatteing intensity measurement has been carried out for the Al-3,82% Cu single crystal in which GP (2) zones are found.

The diffuse intensity around 2 1 0 reflection, which shows a cross like streak, is carefully examined. Warren-Cowley short-range order parameters, a(i), are estimated from the diffuse intensities around 2 1 0 reflection. The component of the intensities coming from atomic displacements was subtracted from the total diffuse intensity. It is found that the equi-intensity contours after the correction of the atomic displacements shows an anisotropic distribution and the GP(2) zone is an ellipsoid with a modified layer structure. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=HidaMoritaka kn-aut-sei=Hida kn-aut-mei=Moritaka aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=MatsumoriNobuo kn-aut-sei=Matsumori kn-aut-mei=Nobuo aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TerauchiHikaru kn-aut-sei=Terauchi kn-aut-mei=Hikaru aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=School of Engineering, Okayama University affil-num=2 en-affil= kn-affil=Department of Physics, Kwansei Gakuin University affil-num=3 en-affil= kn-affil=Department of Physics, Kwansei Gakuin University END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=55 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=1970 dt-pub=19700901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Biologically Active Compounds.

It is important to note, however, that kidney transplantation is not a complete cure because it will not prevent kidney diseases from recurring, thereby producing new physical and psychosocial problems for the recipients. The purpose of this study is to identify the relationship between their quality of life and the recipients' background that may influence the recipients' quality of life. One hundred nineteen recipients responded to our questionnaires which included reason for undergoing the transplantation, how to feel own life, locus of control, quality of life, and so on. The following results were obtained : 81% of the recipients reported that they were feeling positive about life. The recipients, who are undergoing the transplantation to want to live life to the full and having internal locus of control, promoted their sense of good quality of life. It is therefore considered important to initiate nursing intervention before the transplantation, based on some recipient's background. kn-abstract=腎移植は,レシピエントのQOLを高めることで期待される治療法であるが,移植後の拒絶反応や合併症,あるいはそれらに伴う心理社会的問題などによって移植後のQOLに影響を及ぼす危険性を孕んでいる｡本研究では,腎移植後レシピエントのQOL向上を目指した看護援助を検討するために,移植後のQOLに影響すると考えられる移植を受けた理由やそのときの気持ち,ローカスオブコントロールをとりあげた。本研究の目的は,そのようなレシピエントの背景がQOLとどのように関係しているのかを明らかにすることである｡対象者は研究の同意を得た腎移植後のレシピエント119名であり,人生に対する感じ方,移植を受けた理由やそのときの気持ち,ローカスオブコントロール,QOLなどについて自己報告調査を行った｡その結果,レシピエントは移植後に何らかの身体症状や合併症が生じていても,81%の者が人生を肯定的に感じていた｡そして,生活を充実させたいとして移植を受けた者が,また,ローカスオブコントロールの内的統制傾向が強い者ほどQOLを高める傾向にあった｡したがって,看護婦はQOLに影響を及ぼすレシピエントの背景を加味して,移植前から適切な看護援助を行う必要性が示唆された｡ en-copyright= kn-copyright= en-aut-name=HayashiYuko en-aut-sei=Hayashi en-aut-mei=Yuko kn-aut-name=林優子 kn-aut-sei=林 kn-aut-mei=優子 aut-affil-num=1 ORCID= en-aut-name=NakanishiYoshiko en-aut-sei=Nakanishi en-aut-mei=Yoshiko kn-aut-name=中西代志子 kn-aut-sei=中西 kn-aut-mei=代志子 aut-affil-num=2 ORCID= en-aut-name=WatanabeKumi en-aut-sei=Watanabe en-aut-mei=Kumi kn-aut-name=渡邉久美 kn-aut-sei=渡邉 kn-aut-mei=久美 aut-affil-num=3 ORCID= en-aut-name=KanaoNaomi en-aut-sei=Kanao en-aut-mei=Naomi kn-aut-name=金尾直美 kn-aut-sei=金尾 kn-aut-mei=直美 aut-affil-num=4 ORCID= en-aut-name=HoshinaEiko en-aut-sei=Hoshina en-aut-mei=Eiko kn-aut-name=保科英子 kn-aut-sei=保科 kn-aut-mei=英子 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=3 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=4 en-affil= kn-affil=国立病院四国がんセンター affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院看護部 en-keyword=腎移植 (Kidney transplantation) kn-keyword=腎移植 (Kidney transplantation) en-keyword=人生に対する感じ方 (How to feel own life) kn-keyword=人生に対する感じ方 (How to feel own life) en-keyword=移植を受けた理由 (Reason for undergoing transplantation) kn-keyword=移植を受けた理由 (Reason for undergoing transplantation) en-keyword=ローカスオブコントロール (Locus of control) kn-keyword=ローカスオブコントロール (Locus of control) en-keyword=QOL kn-keyword=QOL END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1253 end-page=1265 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of new elemental diet including enriched branched chain amino acids and MCT on massive resection of small bowel in rat kn-title=脂肪（MCT）および高濃度分枝鎖アミノ酸を含有した成分栄養剤の侵襲下における効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of a new enteral diet (ED-9) that was mainly composed of BCAA enriched amino acids, MCT and maltose were examined.

One of the urinary metabolites, 4-methyl-2-pentanol (4M2P) was identified by gas chromatography-mass spectrometry only in the urine of workers exposed to MIBK. Time-weighted average concentration of the mixed solvents for 8 hours were as follows ; MIBK 21.9±15.1 ppm (m±SD), toluene 18.3±8.9 ppm, ethyl benzene 9.6±4.6 ppm, xylene (total) 18.9±12.5 ppm. The regression equation between MIBK concentration X (ppm) in air and 4M2P concentration Y (mg/g creatinine) in the urine was : Y=25X-10.25. Its correlation coefficient was 0.63. Thus the urinary concentration of 4M2P corresponding TLV (Threshould Limit Values : 50ppm) of MIBK was 2.61 (mg/g creatinine). In a subject exposed to pure MIBK, the time-weighted average concentration of MIBK for 6 hours was 42.3ppm and 4M2P concentration in the urine was 0.42 (mg/g creatinine). en-copyright= kn-copyright= en-aut-name=HirotaNaomasa en-aut-sei=Hirota en-aut-mei=Naomasa kn-aut-name=廣田直敷 kn-aut-sei=廣田 kn-aut-mei=直敷 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学講座 en-keyword=MIBK kn-keyword=MIBK en-keyword=ヒトの尿中代謝産物 kn-keyword=ヒトの尿中代謝産物 en-keyword=4-メチル-2-ペンタノール kn-keyword=4-メチル-2-ペンタノール en-keyword=マスクロマトグラフィー kn-keyword=マスクロマトグラフィー en-keyword=メチルイソブチルケトン kn-keyword=メチルイソブチルケトン END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=315 end-page=325 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The metabolism of methyl isobtyl ketone and its biological monitoring Part 1.

The results were as follows : 1) Plasma serotonin levels were higher during the attack stage than non-attack stage in asthmatics. 2) Morphological changes and the aggregation of platelets were observed by scanning electron microscopy after stimulation with platelet activating factor(PAF), CaI, anti-IgE and anti-IgG. 3)The serotonin-releasability of platelets stimulated by CaI was significantly decreased in severe asthmatics, compared with mild asthmatics and normal subjects(p<0.05). However, there were no significant differences between steroid dependent and non-steroid dependent intractable asthmatics in severe asthma. 4) The releasability of serotonin was decreased in most cases during asthmatic attack and was suppressed by aminophyllin. 5) The serotonin-releasability of platelets stimulated by anti-IgG of Candida antigen was remarkably enhanced aftre incubation with serum, although releasability was not increased with heart-treated serum. These results suggest that platelets play an important role in bronchoconstriction induced by various immunological reactions involved with complement activation in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=SunamiKoji en-aut-sei=Sunami en-aut-mei=Koji kn-aut-name=角南宏二 kn-aut-sei=角南 kn-aut-mei=宏二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=platelet kn-keyword=platelet en-keyword=serotonin kn-keyword=serotonin en-keyword=bronchial asthma kn-keyword=bronchial asthma END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5-6 article-no= start-page=419 end-page=426 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Adrenal secretion of catecholamines by inhalation of radon water in relation to an increase of the tissue perfusion rate in rabbits kn-title=ラドン水吸入による家兎の副腎髄質カテコラミン分泌作用―組織循環増加作用との関わりについて― en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the relationship between in the increase in subcutaneous tissue perfusion rate (TPR) upon inhalation of radon water and the vasoactive effects of radon, rabbits inhaled nebulized water containing 14,000-18,000 Bq/1 radon (radon group) taken from Ikeda Mineral Spring, Shimane Pref., Japan. Control rabbits inhaled radon water from the same springs which had been kept for over 10 radon half-life periods. TPR was evaluated 15 minutes after the beginning of inhalation by mass spectrometry. After inhalation for 90 minutes, plasma and adrenal glands were removed, and levels of adrenaline and noradrenaline were analyzed by high-performance liquid chromatography (THI mithod). Each group was divided into 4 subgroups according to intravenously injected medication as follows : 1) no medication (without adrenergic blocker), 2) phentolamine (α-blocker), 0.05mg/kg/min, 3) propranolol (non-selective β-blocker), 1mg/kg, and 4) atenolol (selective β1-blocker), 6mg/kg. In the radon group, plasma adrenaline and noradrenaline levels were significantly higher (p<0.01, p<0.05), and adrenaline and noradrenaline levels were significantly lower (p<0.01, P<0.01), than those in the control group. In the no medication and phentolamine subgroups, TPRs in the radon group were significantly higher than those in the control group (p<0.01, P<0.01). In the propranolol and atenolol subgroups, no significant change of TPR was found. It is suggested that catecholamines are secreted from the adrenal glands upon inhalation of radon water and that the β1-action of catecholamines contributes to the increase in tissue perfusion. en-copyright= kn-copyright= en-aut-name=SuzukaIchio en-aut-sei=Suzuka en-aut-mei=Ichio kn-aut-name=鈴鹿伊智雄 kn-aut-sei=鈴鹿 kn-aut-mei=伊智雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部心臓血管外科学教室 en-keyword=ラドン水 kn-keyword=ラドン水 en-keyword=副腎髄質 kn-keyword=副腎髄質 en-keyword=カテコラミン kn-keyword=カテコラミン en-keyword=組織循環 kn-keyword=組織循環 en-keyword=ホルミシス kn-keyword=ホルミシス END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=1-2 article-no= start-page=153 end-page=164 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of exercise training on glucose tolerance and insulin sensitivity in rats receiving a high fat diet kn-title=高脂肪食飼育ラットの耐糖能，インスリン反応およびインスリン感受性におよぼす運動の効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of exercise training on glucose tolerance and insulin sensitivity was studied in rats receiving a modern-westernized high fat diet, in which 42% of total energy was provided in fat. Rats were neither permitted to exercise actively (gorup E) or forced to be in the sedentary condition (group S) for the first two weeks. In the next 2 weeks, rats in both groups were subjected to either active exercise (group EE and SE) or the sedentary condition (group ES and SS). An intraperitoneal glucose tolerance test and insulin sensitivity test were performed at the end of the first and the second 2 weeks. No significant difference was found among the groups in blood glucose levels after glucose challenge. However, the insulin levels in the group E, SE and EE were significantly lower than those in the groups S, SS and ES, respectively. Sensitivity to exogenous isulin was higher in the group EE and SE than in the group ES and SS, respectively. The epididymal fat pads of the groups S, ES, and SS were heavier than those of the group E, EE and SE, respectively. These findings altogether showed that exercise training restrained the incerase in the body fat of rats receiving a high fat diet and improved their sensitivity to endogenous and exogenous insulin. However, discontinuation of exercise rapidly lowered the insulin sensitivity. These findings suggest that continuous exercise is especially important for the prevention and treatment of diabetes mellitus, even under a westernized high fat diet. en-copyright= kn-copyright= en-aut-name=ShimonuraTomoko en-aut-sei=Shimonura en-aut-mei=Tomoko kn-aut-name=下村智子 kn-aut-sei=下村 kn-aut-mei=智子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科学教室 en-keyword=高脂肪食 kn-keyword=高脂肪食 en-keyword=運動 kn-keyword=運動 en-keyword=耐糖能 kn-keyword=耐糖能 en-keyword=インスリン感受性 kn-keyword=インスリン感受性 en-keyword=インスリン非依存性糖尿病 kn-keyword=インスリン非依存性糖尿病 END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=9-10 article-no= start-page=847 end-page=858 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=199310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Prevalence and psychological features of fragile X syndrome in institutionalized male patients with mental retardation in Japan kn-title=施設入所中の精神遅滞男性における脆弱X症候群の頻度とその臨床心理学的特徴 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the prevalence and psychological features of fragile X syndrome among Japanese, cytogenetic and psychological studies were conducted on 183 institutionalized male retardates. The induction of fra (X) (q27) by MEM-FA medium or fluorodeoxyuridine treatment revealed that 6 (3.3%) patients had fragile X syndrome. Psychological tests in the 6 patients with fragile X syndrome [Fra (X)], 6 control subjects with autism [AU] and 6 with simple mental retardation [MR] showed the following results : (1) on SM social maturity test, overall scores of social skills in Fra (X) were between those in AU and those patients in MR. Behavioral autonomy was much better in Fra (X) than in AU patients ; (2) on CLAC-Ⅱ behavior evaluation, Fra (X) patients had a tendency toward lower developmental levels in verbal and nonverbal expression as well as in handling compared to AU patients ; (3) on DSM-Ⅲ-R test, 3 of the 6 Fra (X) males met the criteria for autism. Fra (X) patients had fewer failures in recognizing others' existence or emotions, to develop relationships with others and to use language appropriately compared to AU patients, but had more defects in imitation of others and adaptation to environmental changes than MR patients. The similarity in the prevalence of the fragile X syndrome in the Japanese male retardates to that reported in Caucasians suggests that Fra (X) is a common genetic disorder affecting all ethnic populations. From the psychological findings, we concluded that Fra (X) patients have strong social aversion and defects in verbal and nonverbal expression which sometimes lead to autism. en-copyright= kn-copyright= en-aut-name=MurakamiMasae en-aut-sei=Murakami en-aut-mei=Masae kn-aut-name=村上政江 kn-aut-sei=村上 kn-aut-mei=政江 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科学教室 en-keyword=脆弱X症候群 kn-keyword=脆弱X症候群 en-keyword=精神発達遅滞 kn-keyword=精神発達遅滞 en-keyword=自閉性障害 kn-keyword=自閉性障害 en-keyword=葉酸欠乏培地 kn-keyword=葉酸欠乏培地 END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=7-12 article-no= start-page=151 end-page=156 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=19971225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physical development of tissue-reacted cationic colloid with protein silver and gold chloride kn-title=組織反応陽性荷電鉄コロンドのプロテイン銀と塩化金による現像 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rat brain sections were treated with fine granular cationic iron colloid, which was prepared by boilling ferric chloride with hydrazine hydrate and cacodylic acid (Murakami et al., 1986).

Physical development had an advantage over Prussian blue reaction in that it produces clear and highly contrasted images under a light microscope. Thus, the perineuronal sulfated proteoglycans and the fine processes of the nerve cells were clearly demonstrated by physical development. en-copyright= kn-copyright= en-aut-name=MurakamiTakuro en-aut-sei=Murakami en-aut-mei=Takuro kn-aut-name=村上宅郎 kn-aut-sei=村上 kn-aut-mei=宅郎 aut-affil-num=1 ORCID= en-aut-name=SuWei Dong en-aut-sei=Su en-aut-mei=Wei Dong kn-aut-name=蘇衛東 kn-aut-sei=蘇 kn-aut-mei=衛東 aut-affil-num=2 ORCID= en-aut-name=HongLuo Jia en-aut-sei=Hong en-aut-mei=Luo Jia kn-aut-name=洪珞珈 kn-aut-sei=洪 kn-aut-mei=珞珈 aut-affil-num=3 ORCID= en-aut-name=PiaoDa Xun en-aut-sei=Piao en-aut-mei=Da Xun kn-aut-name=朴大勛 kn-aut-sei=朴 kn-aut-mei=大勛 aut-affil-num=4 ORCID= en-aut-name=OhtsukaAiji en-aut-sei=Ohtsuka en-aut-mei=Aiji kn-aut-name=大塚愛二 kn-aut-sei=大塚 kn-aut-mei=愛二 aut-affil-num=5 ORCID= en-aut-name=SeoKenji en-aut-sei=Seo en-aut-mei=Kenji kn-aut-name=瀬尾憲治 kn-aut-sei=瀬尾 kn-aut-mei=憲治 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学第二講座 affil-num=2 en-affil= kn-affil=岡山大学医学部解剖学第二講座 affil-num=3 en-affil= kn-affil=岡山大学医学部解剖学第二講座 affil-num=4 en-affil= kn-affil=岡山大学医学部解剖学第二講座 affil-num=5 en-affil= kn-affil=岡山大学医学部解剖学第二講座 affil-num=6 en-affil= kn-affil=健照会セオ病院 en-keyword=Cationic iron colloid kn-keyword=Cationic iron colloid en-keyword=physical development kn-keyword=physical development en-keyword=Prussian blue reaction kn-keyword=Prussian blue reaction en-keyword=protein silver kn-keyword=protein silver en-keyword=gold chloride kn-keyword=gold chloride en-keyword=Bodian's silver impregnation kn-keyword=Bodian's silver impregnation END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=3-8 article-no= start-page=37 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Relationship between pysical and visual image qualiy of asymmetric screen-film syatems kn-title=非対称増感紙-フィルムシステムの物理的画質と視覚的画質の関係 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the relationship betwwn physical and visual image quality of asymmetric screen/film systems.

The way to determine their trading positions is not deterministic but obeys a Gibbs distribution with interactions between the past data and the present trading positions. On the other hand, Group B traders follow the advice reached through the long−range percolation system from the investment adviser.

The application of pesticides has undoubtedly contributed to a remarkable increase and stability in crop production. The heavy use of unsuitable pesticides, however, has brought about various undesirable effects on the agroecosystem and environment. Frequent applications of these pesticides have led to the development of resistance in key pests, and induced a resurgence of primary pests or an upsurge in secondary pests. In order to cope with the issue brought about by almost singular dependence on insecticidal control, the Food and Agriculture Organization’s (FAO) panel of experts proposed a new concept for future pest control, in 1965 as follows: “a pest management system that in the context of the associated environment and the population dynamics of the pest species, utilizes all suitable techniques and methods in a manner as compatible as possible and maintains pest population at levels below those causing economic injury”. The proposal has been called Integrated Pest Management (IPM) since the late 1970s. The proposal includes three key concepts, namely (1) integration of plural control measures, (2) economic injury level (EIL), and (3) population management system. Basecally, IPM integrates fundamental tactics, mainly natural control agents and subsidiary tactics, e.g. agricultural chemicals and physical methods. It is primarily significant in IPM that when both set of tactics are integrated, the latter tactics should not suppress the action of the former. Therefore any agricultural chemicals including pesticides must be highly selective against targeted pests, taking into account the crops, natural enemies and the environment. The concept of EIL suggests that the pest population is not necessarily suppressed completely in IPM and control should be implemented with due consideration to a balance of cost and benefit. The population management system is used for monitoring pest population dynamics to forecast whether or not the pest density will overshoot an EIL. It is also used for assessing the efficacy of control tactics. en-copyright= kn-copyright= en-aut-name=NakasujiFusao en-aut-sei=Nakasuji en-aut-mei=Fusao kn-aut-name=中筋房夫 kn-aut-sei=中筋 kn-aut-mei=房夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=integrated pest management kn-keyword=integrated pest management en-keyword=synthetic insecticide kn-keyword=synthetic insecticide en-keyword=integration of plural control measures kn-keyword=integration of plural control measures en-keyword=economic injury level kn-keyword=economic injury level en-keyword=population management system kn-keyword=population management system END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=99 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physical Image Quality of Rapid Processing Films kn-title=迅速処理用X線フィルムの物理特性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The imaging properties of Konica "new" SR series films and "old" MG-SR series films for rapid processing were measured in combination with green-emitting intensifying screens.

In addition, the conventional system Fuji HR-4/Super HR-S was measured for comparison with new systems. The evaluation method is as follows. The image quality characteristics, speed, contrast, resolution and granularity were measured. The sensitivity and contrast were determined by measuring the MTF (modulation transfer function) and NCTF (normalized contrast transfer function). The granularity was estimated by measuring the Wiener spectrum. The speed of the new systems were improved by 22% to 73%. The dinsities at the maximum gradient value were shifted to high density (2.0-2.7). However, they had 10% to 30% less resolution. The other hand, the granularities were improved by 21% to 37% at 1.0 density. These results suggested that the emphasis of new systems was put on improving the image quality of mediastinum region, maintaining performance of the conventional system. kn-abstract=胸部専用の新しい増感紙／フィルムシステムについて物理的画質特性を測定し、従来のシステムと比較を行った。測定した新システムは、日本コダックのインサイトシステムからHC/IT-1、富士メディカルシステムのADシステムからHG-M/UR-1、コニカのEXシステムからXG-S/ES-C である。従来のシステムとして富士メディカルシステムのHR-4/Super HR-S を使用した。その結果、新システムは22～73％感度は高く、特性曲線においては低濃度部を持ち上げ、最大コントラストは高濃度側にシフトしていた。空間周波数2cycles/mmで相対鮮鋭度を比較すると、新システムが10～30％程度の低下となっていた。ノイズは、濃度1.0で新システムが35～46％の減少となった。以上より、新システムは、縦隔部の濃度を上げ、粒状性の改善を重視した設計となっていることが分かった。 en-copyright= kn-copyright= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name=後藤佐知子 kn-aut-sei=後藤 kn-aut-mei=佐知子 aut-affil-num=1 ORCID= en-aut-name=YoshidaAkira en-aut-sei=Yoshida en-aut-mei=Akira kn-aut-name=吉田彰 kn-aut-sei=吉田 kn-aut-mei=彰 aut-affil-num=2 ORCID= en-aut-name=NakamuraNobue en-aut-sei=Nakamura en-aut-mei=Nobue kn-aut-name=中村伸枝 kn-aut-sei=中村 kn-aut-mei=伸枝 aut-affil-num=3 ORCID= en-aut-name=MaruyamaToshinori en-aut-sei=Maruyama en-aut-mei=Toshinori kn-aut-name=丸山敏則 kn-aut-sei=丸山 kn-aut-mei=敏則 aut-affil-num=4 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=5 ORCID= en-aut-name=ShibuyaKoichi en-aut-sei=Shibuya en-aut-mei=Koichi kn-aut-name=渋谷光一 kn-aut-sei=渋谷 kn-aut-mei=光一 aut-affil-num=6 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=7 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=8 ORCID= en-aut-name=HondaMitsugi en-aut-sei=Honda en-aut-mei=Mitsugi kn-aut-name=本田貢 kn-aut-sei=本田 kn-aut-mei=貢 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=2 en-affil= kn-affil=広島県立保健福祉短期大学部放射線技術科学科 affil-num=3 en-affil= kn-affil=岡山大学歯学部附属病院歯科放射線科 affil-num=4 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=5 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=7 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=8 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 en-keyword=増感紙フィルム系 (screen-film system) kn-keyword=増感紙フィルム系 (screen-film system) en-keyword=物理特性 (physical properties) kn-keyword=物理特性 (physical properties) en-keyword=感度 (speed (film sensitivity)) kn-keyword=感度 (speed (film sensitivity)) en-keyword=コントラスト (contrast) kn-keyword=コントラスト (contrast) en-keyword=鮮鋭度 (resolution) kn-keyword=鮮鋭度 (resolution) en-keyword=粒状性 (granularity) kn-keyword=粒状性 (granularity) END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=2 article-no= start-page=71 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20010324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The reality investigation of stresses which the new figure nurses employed after one month hold kn-title=就職後1ヶ月の新人看護婦の抱えるストレスの実態調査 en-subtitle= kn-subtitle= en-abstract=Revision of curriculum makes reduce the practice time in clinical more and more. On the other hand, in clinical site, the gap between the nursing base education and the clinical site shows the tendency to enlarge because of high-developed medicine and complicated situation. This time, I put into practice the questionnaire survey for 38 new figure nurses to make their having stresses clear. Consequently, they expressed mainly three causes of their stress. They were about the nursing skills (94%), irregular life due to three shifts (14%) and the way of the communication to the patient. There weren't any differences among each nursing curriculum. 32.3% of the new figure nurses having much stresses said about their physical condition that they were not good or not so good. The 6 new figure nurses (17.6%) thought that they wanted to quit their job only one month after being nurse. The 8 new figure nurses (82%) thought that they were satisfied with being nurse. When many new figure nurses could make good communication with their patients, they thought that. The new figure nurses said that they wanted to study about more nursing skills, medicine of transplantation and ME equipments. kn-abstract=看護教育カリキュラムの改正により，臨床での実習時間はますます減る傾向にある。一方，臨床現場では，医療の高度化，複雑化が進み，看護基礎教育と現場のギャップは大きくなる傾向にある。今回38名の新人看護婦にアンケート調査を行い，新人看護婦の抱えるストレスについて明らかにした。その結果，新人看護婦の抱えるストレスは，看護技術に関するストレスが最も多く（94％），ついで，3交代勤務による不規則な生活（14％），患者とのコミュニケーション（11％）であった。この結果には教育課程の違いによる差は認められなかった。多くのストレスの中で働く新人看護婦は，32.3％が，体調についてあまりよくない，あるいは良くないと回答していた。また，様々なストレスにより，就職後1ヶ月で退職を考えているものが6名（17.6％）いた。看護婦になってよかったと答えたものは8名（82％）あり，その多くが，患者との関わりがうまくいったときにそのように感じていた。新人看護婦が，今後の看護基礎教育に望むことは，技術面の体験をさらに増やすこと，移植医療，ME機器の取り扱いなどであった。 en-copyright= kn-copyright= en-aut-name=MoriKeiko en-aut-sei=Mori en-aut-mei=Keiko kn-aut-name=森恵子 kn-aut-sei=森 kn-aut-mei=恵子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 en-keyword=新人看護婦 (The new figure nurse) kn-keyword=新人看護婦 (The new figure nurse) en-keyword=ストレス (stress) kn-keyword=ストレス (stress) en-keyword=リアリティーショック (reality shock) kn-keyword=リアリティーショック (reality shock) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=151 end-page=156 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Importance of Interactive Information Issues in terms of Earthquake Disasters with a Focus on Kobe Case en-subtitle= kn-subtitle= en-abstract= kn-abstract=More than billions of years, Earth activity and earthquakes have functioned as the most important part in shaping the physical features of our Earth, on both social life and environment.

This phase-change material can store latent heat (liquid-solid phase) under the supercooling condition from -10°to 58°without the help of thermal insulation for a long time. This article discusses measured results of physical properties of this phase-change material, i. e., thermal conductivity, spcific heat, latent heat, density, kinematic viscosity and crystal growth speed under various temperatures (solid and liquid phases), including the supercooling condition. en-copyright= kn-copyright= en-aut-name=InabaHideo en-aut-sei=Inaba en-aut-mei=Hideo kn-aut-name=稲葉英男 kn-aut-sei=稲葉 kn-aut-mei=英男 aut-affil-num=1 ORCID= en-aut-name=OtakeHideo en-aut-sei=Otake en-aut-mei=Hideo kn-aut-name=大竹秀雄 kn-aut-sei=大竹 kn-aut-mei=秀雄 aut-affil-num=2 ORCID= en-aut-name=NozuShigeru en-aut-sei=Nozu en-aut-mei=Shigeru kn-aut-name=野津滋 kn-aut-sei=野津 kn-aut-mei=滋 aut-affil-num=3 ORCID= en-aut-name=FukudaTakeyuki en-aut-sei=Fukuda en-aut-mei=Takeyuki kn-aut-name=福田武幸 kn-aut-sei=福田 kn-aut-mei=武幸 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Thermophysical Property kn-keyword=Thermophysical Property en-keyword=Energy Storage kn-keyword=Energy Storage en-keyword=Supercooling kn-keyword=Supercooling en-keyword=Latent Heat kn-keyword=Latent Heat en-keyword=Hydrate Sodium Acetate kn-keyword=Hydrate Sodium Acetate END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=1989 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Water Demand Curve for Rice Paddy Field kn-title=水田における農家の水需要曲線 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Demand for water use in rice paddy fields in Japan has traditionally been measured according to a unit known as "Gensuishin" However, it does not consider farmer decisions on how much water to use in rice production, while the quantity of water measured by "Gensuishin" takes into account biologocal and physical conditions. This paper reports that analysis of water demand in rice production ought to incorporate a farmer's subjective equilibrium and water demand quantity. The water demand curve on a paddy field that is specified here associates with three factors. The first, the farmer's subjective equilibrium of how much water to use in rice production. The second is the two major roles of water playing in rice production. The third is a consideration of the stages of rice growing. There are two important roles which water plays during a rice production cycle. The first words, water is involved in protecting the growth level achieved for each stage, as well as to help the plant in starting its new growth stage. A proper evaluation of the economic values of water in rice production must take into account those two roles. The economic value of water for surviving rice plant increases consistently through growth stages. The value of water for contributing in rice growth should depend on the marginal value product of water inputted into rice production at each growing stage. en-copyright= kn-copyright= en-aut-name=SatohToyonobu en-aut-sei=Satoh en-aut-mei=Toyonobu kn-aut-name=佐藤豊信 kn-aut-sei=佐藤 kn-aut-mei=豊信 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=1986 dt-pub=1986 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=岡山県の集落社会の構造変化 kn-title=The Changing Structure of Okayama Prefecture's Hamlet Communities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rural communities in Okayama Prefecture, like those throughout Japan and the remainder of the industrialized world, have undergone rapid economic and social changes in the post-war period. Both policy makers and scholars who are interested in social change in rural areas need to develop an understanding of what those changes have been, what they might be leading to and what the impacts of those changes have been on communities and the people who live there, if they are to effectively promote the social health of these communities. This paper is the first in a series of articles which will carry out such an investigation using the hamlet communities of Okayama Prefecture as the primary data base. This first paper, through an analysis of data on these communities collected by the Japanese Ministry of Agriculture, Fisheries and Forestry will present findings which will delineate the main structural changes which these hamlets underwent in the 1960 to 1980 period. Basically, it will be shown that the two most important factors explaining the evolution of the current structure of these communities are their size and their proximity to major urban areas. While the effects of rapid industrialization have led to a decrease in the importance of agriculture throughout all of the hamlets of the prefecture, the new form into which a hamlet has evolved depends in large measure on its physical location within the prefecture, and its size, as measured by the number of houses and area of cultivated land. en-copyright= kn-copyright= en-aut-name=JussaumeRaymond A.
