The results indicate that a five-layer S-wave velocity structure from the surface to the seismic basement equivalent layer with thicknesses of 8, 24, 80 and 180 m and velocities of 150, 450, 1100, 1700 and 3200 m/s, respectively, is reasonable. This model explains to some extent the observed phase velocity and H/V spectral ratios. It is also consistent with the surface borehole results. Furthermore, the areal characteristics of the H/V spectral ratios were also presented, allowing us to estimate the trend of the ground structure in shallow areas. en-copyright= kn-copyright= en-aut-name=YAMADANobuyuki en-aut-sei=YAMADA en-aut-mei=Nobuyuki kn-aut-name=山田伸之 kn-aut-sei=山田 kn-aut-mei=伸之 aut-affil-num=1 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Science and Technology, Kochi University kn-affil=高知大学理工学部地球環境防災学科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Okayama kn-keyword=Okayama en-keyword=Microtremor array exploration kn-keyword=Microtremor array exploration en-keyword=S-wave velocity kn-keyword=S-wave velocity en-keyword=H/V spectral ratio kn-keyword=H/V spectral ratio END start-ver=1.4 cd-journal=joma no-vol=592 cd-vols= no-issue= article-no= start-page=121751 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of bond valence sum on the structural modeling of lead borate glass en-subtitle= kn-subtitle= en-abstract= kn-abstract=The structural model of 66.7PbO-33.3B2O3 glass was constructed using a reverse Monte Carlo (RMC) method, in which bond valence sum (BVS) was added as a constraint condition to suppress formation of unrealistic local structures. Based on the crystal structures, the optimal BVS calculating conditions were determined. As a result, BVS distributions with small deviation were successfully achieved without lowering the reproducibility of other experimental constraints. The geometric asymmetry of PbOn polyhedra was evaluated from the eccentric distance between Pb and gravity center of oxygen atoms. The average eccentric distance was shorter than that in the lead borate crystals, indicating less asymmetry of PbOn units in the RMC glass model. The connectivity between BOn and PbOn units was investigated. It was consequently concluded that the glass had a different network structure from the crystal with the same composition, which might be due to the different chemical bonding character between the lead borate glasses and crystals. en-copyright= kn-copyright= en-aut-name=NagaoMasaaki en-aut-sei=Nagao en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukunokiAtsushi en-aut-sei=Mukunoki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChibaTamotsu en-aut-sei=Chiba en-aut-mei=Tamotsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KikuchiTakahiro en-aut-sei=Kikuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakuragiTomofumi en-aut-sei=Sakuragi en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OwadaHitoshi en-aut-sei=Owada en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Environmental Management Center, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=JGC Japan Corporation kn-affil= affil-num=6 en-affil=JGC Japan Corporation kn-affil= affil-num=7 en-affil=JGC Japan Corporation kn-affil= affil-num=8 en-affil=Radioactive Waste Management Funding and Research Center kn-affil= affil-num=9 en-affil=Radioactive Waste Management Funding and Research Center kn-affil= en-keyword=Lead borate glass kn-keyword=Lead borate glass en-keyword=Reverse Monte Carlo modeling kn-keyword=Reverse Monte Carlo modeling en-keyword=Bond valence sum kn-keyword=Bond valence sum en-keyword=Coordination polyhedron kn-keyword=Coordination polyhedron END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=8 article-no= start-page=605 end-page=610 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202281 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental activities on glass in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In general, glass has been recognized as an environmentally friendly material. However, the production of glass requires a lot of heat energy, and the raw materials also emit CO2 at the melting process. In fact, commercial glasses are not easy to recycle. In glass industry of Japan, various efforts have been made so far to reduce the environmental impact of glass. In this paper, not only glass manufacturing technologies but also glass recycling technologies were reviewed, and the future glass production technologies to achieve carbon neutrality were also introduced. en-copyright= kn-copyright= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkaiTomoko en-aut-sei=Akai en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=11 article-no= start-page=405 end-page=412 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Formation Mechanism of Tempering-Induced Martensite in Ti-10Mo-7Al Alloy kn-title=Ti–10Mo–7Al合金の焼戻し誘起マルテンサイトの形成機構 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The formation mechanism of αAA–martensite (αAAMt) induced by tempering at 450–550℃ for a short time was investigated using Ti–10Mo–7Al alloy. The solution treated and quenched (STQ) sample was composed of β phase and a small amount of αAAMq, and a large amount of αAAMt was generated by rapid tempering at 550℃–3 s using a salt bath. However, αAAMt was completely transformed into a single β phase by aging at 200℃ for 3 min. Reversibility was observed between the αAAMt transformation and the β reverse transformation. In–situ high–temperature X–ray diffraction measurements revealed that αAAMq → β reverse transformation occurred at 200℃ and that a thermally activated αAAiso was generated at 450℃ due to the slow heating rate. In–situ optical microscopic observation of STQ sample with rapid lamp heating revealed that αAAMt was formed during heating process. However, αAAMt did not generate under following conditions; that is, a slow heating rate, thin sample plate, and a small temperature difference until tempering by preheating. On the other hand, rapid tempering using thick plate from liquid nitrogen (−196℃) to 250℃ was performed to ensure a sufficient temperature difference, but αAAMt was not generated at all. From the cross–sectional observation of the STQ plate, it was found that αAAMq was hardly formed on the surface of the sample, but was formed abundantly inside the sample. On the other hand, in the rapidly tempered plate, a large amount of αAAMt was distributed in the surface layer than inside sample. These results suggest that the thermal compressive stress induced by rapid heat treatment contributes to the formation of α''M. en-copyright= kn-copyright= en-aut-name=TakemotoYoshito

sprinkled on the asphalt surface during the hottest hours of the day using a sprinkler, and the effect was experimentally verified. An air temperature, a humidity, a ground surface temperature, and a globe temperature which is radiant heat from the ground were measured, and using these measurements, WBGT (Wet-Bulb Globe Temperature), which is an index of thermal stress on the human body, was calculated. In this way, we investigated not only the climate mitigation effect but also the mitigation effect of the thermal environment felt by the human body.
As a result, the following points were clarified in this study: 1) During sprinkling, the air temperature, the black globe temperature, and the WBGT were lower in the sprinkled area than in the controlled area, and the wet-bulb temperature hardly changed. 2) Focusing on the amount of change after watering compared to before watering, the air temperature, the globe temperature, and the WBGT decreased, and the wet-bulb temperature hardly changed. 3) In the sprinkled area, when the WBGT value just before watering is higher than that of the strict caution (WBGT is 28°C or higher), it drops to a level one rank lower, and when the WBGT value just before watering is warning (WBGT value is 25°C or higher), it was almost no change. en-copyright= kn-copyright= en-aut-name=MOROIZUMIToshitsugu en-aut-sei=MOROIZUMI en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=1 ORCID= en-aut-name=ITONaoya en-aut-sei=ITO en-aut-mei=Naoya kn-aut-name=伊藤尚也 kn-aut-sei=伊藤 kn-aut-mei=尚也 aut-affil-num=2 ORCID= en-aut-name=MIURATakeshi en-aut-sei=MIURA en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil= kn-affil=前田道路㈱ affil-num=3 en-affil= kn-affil=岡山大学大学院環境生命科学研究科（名誉教授） en-keyword=WBGT kn-keyword=WBGT en-keyword=Air temperature kn-keyword=Air temperature en-keyword=Globe Temperature kn-keyword=Globe Temperature en-keyword=Thermal environment kn-keyword=Thermal environment en-keyword=Sprayed water kn-keyword=Sprayed water END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of actual evapotranspiration in 3 river basins in Okayama prefecture - Comparison of Morton method and modified Brutsaert & Stricker method - kn-title=岡山県3河川流域における実蒸発散量の推定 : Morton 法と修正 Brutsaert and Stricker 法の比較 en-subtitle= kn-subtitle= en-abstract= kn-abstract= In the study, the actual evaporation was estimated in the Asahi River, the Takahashi River, and the Yoshii River basins in Okayama prefecture for four years from January 1999 to December 2002. The Morton method and the modified Brutsaert and Stricker (B & S) method were applied to the three river basins to estimate the actual evapotranspiration and compare the two methods.
As a result, the actual evapotranspiration by the Morton method was all almost equal to that by the Penman’s potential evapotranspiration, and the evapotranspiration was overestimated rather than the actual evapotranspiration. The actual evapotranspiration by the modified B & S method was below the Penman’s potential evapotranspiration throughout the year, and the total annual amount was about 80% of the potential evapotranspiration. In addition, the modified B & S method showed the general tendency that the actual evapotranspiration was lower in urban area than in the hilly and mountainous areas. en-copyright= kn-copyright= en-aut-name=MOROIZUMIToshitsugu en-aut-sei=MOROIZUMI en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=1 ORCID= en-aut-name=MIURATakeshi en-aut-sei=MIURA en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院環境生命科学研究科（名誉教授） en-keyword=Complementary relationship kn-keyword=Complementary relationship en-keyword=Actual evapotranspiration kn-keyword=Actual evapotranspiration en-keyword=Potential evapotranspiration kn-keyword=Potential evapotranspiration END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= 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= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Agrostis avenacea J.F.Gmel. kn-title=ナンカイヌカボ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-keyword=イネ科 (Poaceae) kn-keyword=イネ科 (Poaceae) END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=51 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境理工学部 博士論文 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=49 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境理工学部 研究受賞等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=39 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境物質工学科 学術論文等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=27 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境管理工学科 学術論文等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=13 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境デザイン工学科 学術論文等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=5 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境数理学科 学術論文等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Efficient modelling of 3-d finite element mesh formation with use of 3-d topographic survey kn-title=3次元計測を利用した効率的な3次元有限要素モデル化法の提案 en-subtitle= kn-subtitle= en-abstract= kn-abstract= In this decade, 3-dimensional topographic survey has been developed by using the UAV as like drones.

are many limitations and difficulties in terms of expanding agricultural lands. Also, some other factors affect the agricultural lands that result in decreases such as climate change, erosion and misuse of the lands. It is clear that these developments in agricultural land use threaten the future of human welfare, social conditions, economic growth and food supply. In this study, we examined the land use and its significance that represent past agriculture and regional characteristics in the Chugoku region including Okayama prefecture and the Seto Inland Sea. Specifically, among the products called as industrial crops, such as cotton, pyrethrum, rush, tobacco, rapeseed, mulberry and tea, were adopted as the indicators. Currently, these landscapes can hardly be seen, only leaves of tobacco and tea can still be seen in mountainous areas. Even in agricultural land usewhich has almost disappeared now, it may have indirect influence as in the case of reclaimed land and rush products. Therefore, we reaffirmed in this study the reasons for their existence and their significance. en-copyright= kn-copyright= en-aut-name=FumikazuIchiminami en-aut-sei=Fumikazu en-aut-mei=Ichiminami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Meltem Okur Dinçsoy en-aut-sei=Meltem Okur Dinçsoy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Enver Erdin Dinçsoy en-aut-sei=Enver Erdin Dinçsoy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Economics and Administrative Sciences, Trakya University kn-affil= affil-num=3 en-affil=School of Applied Sciences, Trakya University kn-affil= en-keyword=industrial crop kn-keyword=industrial crop en-keyword=cultivated area kn-keyword=cultivated area en-keyword=rural geography kn-keyword=rural geography en-keyword=agriculture kn-keyword=agriculture en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=23 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Transitional Analysis on the Production of Cereals, Beans and Potatoes in Okayama Prefecture en-subtitle= kn-subtitle= en-abstract= kn-abstract= The contribution of cereals to economies is undoubtedly very important and has many dimensions in terms of use of cultivated areas, agricultural production, nutrition, domestic and foreign trade and national income. In this study, we examined the characteristics of agricultural production in Okayama prefecture from the viewpoint of grain, beans and potatoes excluding rice, wheat and barley in the long term. These are undoubtedly supposed to have a certain role in complementing the function as the staple food of rice and wheat, etc.Also, according to our literature investigations, researchers have not focused on this context for Okayama Prefecture by not spending enough attention in the past. Therefore, we focus on these subjects in this paper by examining a historical significance. It is observed that some planting area and yield of crops have drastically reduced in Okayama prefecture. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=Enver Erdin Dinçsoy kn-aut-sei=Enver Erdin Dinçsoy kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FumikazuIchiminami en-aut-sei=Fumikazu en-aut-mei=Ichiminami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Meltem Okur Dinçsoy en-aut-sei=Meltem Okur Dinçsoy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=School of Applied Sciences, Trakya University kn-affil= affil-num=2 en-affil=Faculty of Environmental Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Economics and Administrative Sciences, Trakya University kn-affil= en-keyword=cultivated area kn-keyword=cultivated area en-keyword=cereals kn-keyword=cereals en-keyword=buckwheat kn-keyword=buckwheat en-keyword=beans kn-keyword=beans en-keyword=potatoes kn-keyword=potatoes en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=1 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Long Term Change of Agricultural Production in Okayama Prefecture in terms of Rice, Wheat and Barley en-subtitle= kn-subtitle= en-abstract= kn-abstract= The current ratio of dependence on food in Japan has remarkably grown and the significance of food self-sufficiency by concurrent agriculture may decline, while importantly conserving the natural environment, appropriate management of farmland. Okayama prefecture has an agricultural trend over more than 100 years of rice, barley and wheat cropping area with the rise and fall of its agricultural land use from the prior to the Industrial Revolution in Japan. Although rice reduction policy in Japan is scheduled to end in 2017, Japan is strongly subject to rice compared to other grains. In order to understand the role and scope of the agricultural sector in Okayama pref., it is necessary to review the changes in the related agricultural products for the long term. In Okayama pref., the cultivation and processing of some industrial crops including sericulture sector were thriving in the past, but, commercial agriculture was not well developed and the meaning of the production of cereals was greater than current production. Considering the part of agricultural characteristics by examining the cultivation of crops over the long term, planting area survey by variety confirmed that the greatest feature of rice cultivation in Okayama pref. is the diversity of varieties. In addition to various rice varieties, agriculture in Okayama pref. has a high sustainability, resistance and flexibility against changes on climate, policies and land use. en-copyright= kn-copyright=

cash crop have spread rapidly. Valid response from 24 farmers were obtained and Asparagus had been planted in 30 plots within 74 plots (40.5%). As the result of statistical analysis on the geospatial preference for asparagus fields by logit model in which the geospatial characteristics of plots such as elevation, slope, curvature, acreage and distance from farmhouse were adapted as the explanatory variables while the category of the cultivated crops in there was adapted as the independent variable, it became clear that as for the asparagus plots, small lots were more preferred. On the other hand, the geospatial preference for asparagus plots such as elevation, slope, curvature and distance from farmhouse did not became clear. en-copyright= kn-copyright= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=1 ORCID= en-aut-name=HironakaShoya en-aut-sei=Hironaka en-aut-mei=Shoya kn-aut-name=弘中奨也 kn-aut-sei=弘中 kn-aut-mei=奨也 aut-affil-num=2 ORCID= en-aut-name=MatsumotoYuki en-aut-sei=Matsumoto en-aut-mei=Yuki kn-aut-name=松本雄樹 kn-aut-sei=松本 kn-aut-mei=雄樹 aut-affil-num=3 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 affil-num=2 en-affil= kn-affil=倉敷市役所 affil-num=3 en-affil= kn-affil=復建調査設計株式会社 en-keyword=Land use kn-keyword=Land use en-keyword=GIS kn-keyword=GIS en-keyword=Thailand kn-keyword=Thailand en-keyword=Asparagus kn-keyword=Asparagus en-keyword=logit model kn-keyword=logit model END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=61 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation of drop in official air temperature record at Okayama caused by relocation of observation field of Okayama Local Meteorological Observatory - By comparison with records observed at surrounding points - kn-title=岡山地方気象台観測露場移転による気温低下量の推定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Statistical change in official temperature records at Okayama City caused by relocation of meteorological observation field of Meteorological Agency was evaluated. The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃. en-copyright= kn-copyright= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=1 ORCID= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=2 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=3 ORCID= en-aut-name=ChikamoriHidetaka en-aut-sei=Chikamori en-aut-mei=Hidetaka kn-aut-name=近森秀高 kn-aut-sei=近森 kn-aut-mei=秀高 aut-affil-num=4 ORCID= en-aut-name=KurokawaMasahiro en-aut-sei=Kurokawa en-aut-mei=Masahiro kn-aut-name=黒川正宏 kn-aut-sei=黒川 kn-aut-mei=正宏 aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=中嶋佳貴 kn-aut-sei=中嶋 kn-aut-mei=佳貴 aut-affil-num=6 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=7 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 affil-num=2 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 affil-num=3 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 affil-num=4 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 affil-num=5 en-affil= kn-affil=岡山大学環境理工学部 affil-num=6 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 affil-num=7 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 en-keyword=Okayama Local Meteorological Observatory kn-keyword=Okayama Local Meteorological Observatory en-keyword=relocation kn-keyword=relocation en-keyword=drop in air temperature kn-keyword=drop in air temperature END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=55 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Method for predicting minimum air temperature in the next morning using local meteorological observation data - Improvement on minimum air temperature forecasting system utilizing the Internet - kn-title=現地気象観測データを用いた最低気温予測方法とその精度―インターネットを利用した最低気温予報システムの改良― en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have developed a minimum air temperature forecasting system using local meteorological observation data in order to prevent or mitigate the frost damage. In this paper, the correlation between the meteorological factors and the decrease in air temperature during the night was shown. Then minimum air temperature was predicted by the multiple regression equation that uses air temperature and humidity at 18:00 as explanatory variables. As the result, the root mean square error (RMSE) was 2.8°C. When the difference of air temperature between 17:00 and 18:00 was used for the prediction instead of humidity, the RMSE was 3.5°C. Next, the prediction was carried out only in clear nights, then the equation that use air temperature and humidity at 18:00 showed that the RMSE was 1.3°C. Although the predictive accuracy of the equations for clear nights is low on cloudy or rainy nights, we can forecast safely on frosty nights by using those equations in combination with the equations for all nights. en-copyright= kn-copyright= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=1 ORCID= en-aut-name=MishimaTakuya en-aut-sei=Mishima en-aut-mei=Takuya kn-aut-name=三島拓也 kn-aut-sei=三島 kn-aut-mei=拓也 aut-affil-num=2 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=4 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 affil-num=2 en-affil= kn-affil=エイト日本技術開発株式会社 affil-num=3 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 affil-num=4 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 en-keyword=Minimum air temperature kn-keyword=Minimum air temperature en-keyword=prediction kn-keyword=prediction en-keyword=frost damage kn-keyword=frost damage en-keyword=IT kn-keyword=IT en-keyword=multiple regression analysis kn-keyword=multiple regression analysis END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=29 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Changing Food Production based on Agricultural Enterprises in Tottori Prefecture kn-title=経営部門からみた鳥取県の食料生産の変貌 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aims to explain the main features of food production in Tottori prefecture focusing on agricultural enterprises. First, the number of farmers and farm households, the area of cultivated land, and their spatial distribution were analyzed. Then, the production trend on rice, livestock, vegetables such as watermelon and leek, and pears was surveyed. Furthermore, by overlooking the features of each enterprise, food production as a regional agriculture was briefly examined. Farm management in Tottori pref. has long been a small scale selfsufficiency property, but has gradually decayed or specialized. Because agricultural workers are continuously decreasing and aging, farming in Tottori pref. should pay attention to the demand of world food while publicizing a process on food production and farmmanagement carefully. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 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 en-keyword=food production kn-keyword=food production en-keyword=enterprise kn-keyword=enterprise en-keyword=vegetables kn-keyword=vegetables en-keyword=pears kn-keyword=pears en-keyword=Tottori prefecture kn-keyword=Tottori prefecture END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=1 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tourism Inventory of Okayama Prefecture: An Analysis on Main Sightseeing Spots in terms of the Number of Tourists en-subtitle= kn-subtitle= en-abstract= kn-abstract= At the early stage of this paper, Okayama prefecture was analyzed by the author focusing on the tendency of main sightseeing-areas based on the number of tourists for three decades (Ichiminami, 2002). In this study, the main sightseeing spots in Okayama pref. are also examined and the developments are explained in a more detailed and updated perspective by extending over current features and the number of tourists. One of the important reasons in a significant increase in tourists in Okayama is the opening of the highways, the bullet train and cross-linking of the Seto Ohashi Bridge. At the same time, there are some waves in the increase or decrease of the tourist trends appearing from several vital developments such as environmental, climatic, social, economic and spatial. In this regard, research objectives of the study are mainly based on investigating and making a comprehensive study on main sightseeing spots in Okayama pref. to find new tourism values and to provide a tourism inventory of Okayama pref. by means of information, data and clues from the field in/between the tourist destinations such as hotel guests, gardens and castles. Therefore, Okayama pref. has a rich potential of historical and cultural heritage in terms of spatial planning and growth. The important point is that the structural adaptation between historical and cultural assets and the city life should be provided and protected for domestic and foreign tourism as much as creating better futures in health tourism, gastronomy tourism, cultural tourism, belief tourism, congress tourism, thematic tourism and local tourism. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu

kn-abstract=Turkey has been undergoing very important economic and social changes since several decades such as economic growth, privatization of state enterprises, liberalization, and integration with the EU, and legislative reforms. All sectors in Turkey and production levels are affected by these changes during the years. Crop production in agriculture is one of the most affected sectors. Many policies by governmental/nongovernmental organizations have been applied and supported for the development of the sector such as modernization, mechanization, irrigation, road constructions, potable water, financial supports, agricultural insurance, and technical supports. Therefore, the main purpose of this paper is to look back and analyze the trend of agricultural changes, land use and related production levels in Turkey. en-copyright= kn-copyright=

in the next morning from the meteorological data, such as air temperature, humidity, and the amount of solar radiation, in a field in the evening on the previous day. The meteorological data are sent to a relay server, and then, transferred to a PC in our laboratory of Okayama University by executing the computer program to import the data which are used to calculate the predicted values of minimum air temperature. The predicted minimum air temperatures are released for the farmers on the website in the server of Okayama University. The website is also created by our laboratory. As a result, the predicted minimum air temperatures agreed with the measured ones. en-copyright= kn-copyright= en-aut-name=MishimaTakuya en-aut-sei=Mishima en-aut-mei=Takuya kn-aut-name=三島拓也 kn-aut-sei=三島 kn-aut-mei=拓也 aut-affil-num=1 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院 環境生命科学研究科 en-keyword=Minimum air temperature kn-keyword=Minimum air temperature en-keyword=prediction kn-keyword=prediction en-keyword=internet kn-keyword=internet en-keyword=frozen disaster kn-keyword=frozen disaster END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=13 end-page=33 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=Production and Shipment of Eggplant in Okayama Prefecture　Focusing on the Eggplant Cultivation in Greenhouse in the 7th Division of the Kojima Bay Reclaimed Land kn-title=岡山県におけるナス生産と出荷　児島湾干拓地第七区の施設ナスを中心として en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The main purpose of this study is to explain the production and shipment of eggplant and the management of farm households in the 7th division of the Kojima bay reclaimed land in Okayama prefecture. 10 pioneers began to cultivate eggplant in a greenhouse in 1969 and the number of farm households, acreage and shipment increased dramatically until the early 1980s. However, decline or stagnation trend has continued thereafter. Farm workers are often 50 years old or more, each farmer has cultivated eggplant, rice, two-rowed malting barley in family management by 2 or 3 persons. Work begins in July. Eggplant seedlings are planted in August, harvest begins in October and heating in November. Pest control is necessary throughout the year, but pesticide use has decreased in recent years. In order to suppress the occur -rence of the pests, workers use both the bunker crops like sesame and natural enemies like Amblyseius swirskii . However, because the prices of agricultural materials and fuel are recently soaring, the farm management of eggplant has become increasingly severe. We propose to expand the sales network by advertising and a more aggressive acceptance of new farmers. en-copyright= kn-copyright= en-aut-name=FurutaYuichiro en-aut-sei=Furuta en-aut-mei=Yuichiro kn-aut-name=古田祐一郎 kn-aut-sei=古田 kn-aut-mei=祐一郎 aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=生活協同組合おかやまコープ affil-num=2 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=eggplant kn-keyword=eggplant en-keyword=greenhouse kn-keyword=greenhouse en-keyword=pest control kn-keyword=pest control en-keyword=farm management kn-keyword=farm management en-keyword=agricultural cooperative kn-keyword=agricultural cooperative en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=1 end-page=11 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=Preliminary study on the preserved trees in the central part of Himeji city and Syosya-zan Engyo-ji in terms of civil consciousness en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study investigated the civil consciousness on the preserved trees in Himeji city, Hyogo prefecture. We conducted data collection in the city hall,,observed preserved trees, and examined the awareness of citizens against the preserved trees in the central area and Syosya-zan Engyo-ji. As a result, it was revealed that the citizens are not indifferent to the natural environment of trees, etc., they also do not have a strong interest in it in particular. As for preserved tree system, there were some slight differences in the recog -nition between the people who actually take care of trees and administration. People are in favor of the need for the current system of preserved trees. However, in Japan, which is blessed with many things, people do not recognize strongly appreciating the natural environment. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NoguchiYukiko en-aut-sei=Noguchi en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DinçsoyMeltem Okur en-aut-sei=Dinçsoy en-aut-mei=Meltem Okur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DinçsoyEnver Erdinç en-aut-sei=Dinçsoy en-aut-mei=Enver Erdinç kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=JA Hyogo Informatin Center affil-num=3 en-affil= kn-affil=Faculty of Economics and Administrative Sciences, Trakya University affil-num=4 en-affil= kn-affil=Department of Banking, School of Applied Sciences, Trakya University en-keyword=preserved tree kn-keyword=preserved tree en-keyword=ordinance kn-keyword=ordinance en-keyword=civil consciousness kn-keyword=civil consciousness en-keyword=Himeji city kn-keyword=Himeji city END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page= end-page= 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=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page= end-page= 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=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=5 article-no= start-page=317 end-page=324 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Integrated Analyzing Method for the Progress Event based on Subjects and Predicates in Events kn-title=事象の主体と振舞に注目した進展事象の統合解析法 en-subtitle= kn-subtitle= en-abstract=　It is expected to make use of the knowledge that was extracted by analyzing the mistakes of the past to prevent recurrence of accidents. Currently main analytic style is an analytic style that experts decipher deeply the accident cases, but cross-analysis has come to an end with extracting the common factors in the accident cases. We propose an integrated analyzing method for progress events to analyze among accidents in this study. Our method realized the integration of many accident cases by the integration connecting the common keyword called as “Subject” or “Predicate” that are extracted from each progress event in accident cases or near-miss cases. Our method can analyze and visualize the partial risk identification and the frequency to cause accidents and the risk assessment from the data integrated accident cases. The result of applying our method to PEC-SAFER accident cases identified 8 hazardous factors which can be caused from tank again, and visualized the high frequent factors that the first factor was damage of tank 26 ％ and the second factor was the corrosion 21 ％, and visualized the high risks that the first risk was the damage 3.3×10^(-2)[risk rank / year] and the second risk was the destroy 2.5×10^(-2)[risk rank / year] . kn-abstract=　事故の再発防止には，過失を解析し将来に活かす事が求められている．ただ，現在の解析は，専門家が事例を深く読み解く解析が主であり，複数の事例を横断した解析は共通要因の抽出迄に留まっている．　そこで，本研究では従来の横断解析法を高度化した進展事象の統合解析法を提案する．本手法は，事故やヒヤリハット等事例の進展事象を主体と振舞という単位のキーワードに分離し，同一の主体と振舞に該当するキーワードを連結する統合化により，事例の横断解析を可能にした．そして，事象の進展経路とその経路を辿る頻度を基に，危険同定，頻度解析，部分的なリスク解析と，その可視化を実現した．　本統合解析法をPEC事故事例423件へ適用した結果，タンクから再発しうる危険事象を8種類と同定し，頻度が高い要因は破損26 ％，腐食21 ％，高いリスクは破損3.3×10^(-2)［リスクランク／年］，破壊2.5×10^(-2)［リスクランク／年］である事を可視化できた． en-copyright= kn-copyright= en-aut-name=MINOWAHirotsugu en-aut-sei=MINOWA en-aut-mei=Hirotsugu kn-aut-name=箕輪弘嗣 kn-aut-sei=箕輪 kn-aut-mei=弘嗣 aut-affil-num=1 ORCID= en-aut-name=MUNESAWAYoshiomi en-aut-sei=MUNESAWA en-aut-mei=Yoshiomi kn-aut-name=宗澤良臣 kn-aut-sei=宗澤 kn-aut-mei=良臣 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学自然科学研究科 affil-num=2 en-affil= kn-affil=広島工業大学 工学部 機械システム工学科 en-keyword=進展事象の連結 kn-keyword=進展事象の連結 en-keyword=事例の横断解析 kn-keyword=事例の横断解析 en-keyword=リスク評価 kn-keyword=リスク評価 en-keyword=リスク可視化 kn-keyword=リスク可視化 en-keyword=事故事例解析 kn-keyword=事故事例解析 END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=5 article-no= start-page=295 end-page=302 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Image Recognition Method to Measure Angular Velocity from Movement of a Back of Hand for Safety Education kn-title=安全教育のため手の甲によるバルブ速度測定画像認識法 en-subtitle= kn-subtitle= en-abstract=　The realization of training of virtual reality is expected to prevent the accidents caused by human factor. The benefits of training in virtual environment is a realization of training in a simulated real environment. However, there is a problem that a trainee cannot train in the simulated real environment because there is no user interface （UI） to transmit the valve operations which is basic manipulation in the industrial plant to the training system. In this study, we propose an image recognition method for developing a valve manipulation UI which aims to realize the training of valve opening manipulation in virtual environment. The method to measure the angular velocity of the circular handle of a valve utilizes the optical natural feature points obtained from the hand turning the handle. The advantage of our valve manipulation UI is that the UI can construct easily by popular products such as PC, web camera. Our method was revealed to be able to be applied to the UI of training system for worker to train valve operating manipulation which assumed fire risk because it can measure the velocity of 22.5～90 deg/s. kn-abstract=　人的要因の事故を防止する為，仮想現実感を利用した訓練の実現が期待されている．仮想環境での訓練の利点は実環境に近い環境で訓練できる点にある．しかし，プラント内で基本操作であるバルブの操作をシステムへ伝えるユーザ・インタフェース（UIと省略）は現在なく，実環境に即した訓練ができない問題がある． 　そこで本研究では，仮想環境におけるバルブ開操作訓練を実現するバルブ操作UI開発のため，バルブの丸ハンドルの回転速度を測定する画像認識手法を提案する．本手法はバルブの丸ハンドルを回す手から取得した光学的自然特徴点を利用する．本バルブ開操作UIはPC，Webカメラといった一般的な製品を用い平易に実現できる利点がある． 　本手法は，評価実験で22.5-90deg/sを測定できる事を確認できたため，発火危険を想定したバルブ操作訓練のためのUIに適用できる事が明らかとなった． en-copyright= kn-copyright= en-aut-name=MINOWAHirotsugu en-aut-sei=MINOWA en-aut-mei=Hirotsugu kn-aut-name=箕輪弘嗣

The dispersion and polar components of surface free energy indicated high correlation with the bond overlap population of the surface bonds and the net charge of inside atoms of the cluster models, respectively.

In Japan, rice which is suitable for subtropical zone is grown even in an environment of cool-temperate climate. Since the rice varieties that resist of cold weather have been developed, rice cultivation spread to north parts of the country gradually. Land productivity of rice has also improved markedly. As a result, northern Japan became the main producer of rice. Now, taking not only crop production but also the landscape formation and preservation of the natural environment into account, we should think about the rural society from different aspects. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DinçsoyMeltem Okur en-aut-sei=Dinçsoy en-aut-mei=Meltem Okur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DinçsoyEnver Erdinç en-aut-sei=Dinçsoy en-aut-mei=Enver Erdinç kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Economics and Administrative Sciences, Trakya University, Turkey affil-num=3 en-affil= kn-affil=Department of Banking, School of Applied Sciences, Trakya University, Turkey en-keyword=Global warming kn-keyword=Global warming en-keyword=rice cultivation kn-keyword=rice cultivation en-keyword=varieties kn-keyword=varieties en-keyword=acreage kn-keyword=acreage en-keyword=yield kn-keyword=yield en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Numerical Evaluation of the Approximation by an Influence Function kn-title=影響関数による近似の数値評価 en-subtitle= kn-subtitle= en-abstract= kn-abstract=For evaluating statistical models one of the most effective criteria is cross-validation.

By the numerical simulation we studied the effect of an influence function.　 Surveying data of the lake depth are used as the sample data. We estimate the shape of lake bottom as spline surface. The estimated parameters and the estimated depths obtained by two criteria are compared and the effect of an information function is analysed. en-copyright= kn-copyright= en-aut-name=BaoHong Mei en-aut-sei=Bao en-aut-mei=Hong Mei kn-aut-name=包紅梅 kn-aut-sei=包 kn-aut-mei=紅梅 aut-affil-num=1 ORCID= en-aut-name=FuedaKaoru en-aut-sei=Fueda en-aut-mei=Kaoru kn-aut-name=笛田薫 kn-aut-sei=笛田 kn-aut-mei=薫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境生命科学研究科 en-keyword=influence function kn-keyword=influence function en-keyword=information criteria kn-keyword=information criteria en-keyword=CV kn-keyword=CV en-keyword=mGIC kn-keyword=mGIC en-keyword=B-spline kn-keyword=B-spline END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=1 article-no= start-page=108 end-page=113 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distribution behavior of inorganic constituents in chemical recycling processes of a municipal waste slag en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OmuraKohei en-aut-sei=Omura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Chemical recycling of wastes kn-keyword=Chemical recycling of wastes en-keyword=Glass kn-keyword=Glass en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Dissolution–reprecipitation kn-keyword=Dissolution–reprecipitation en-keyword=Elemental mapping kn-keyword=Elemental mapping END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=152 end-page=174 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural problems of regional development practices in terms of sectoral GDP per capita in Turkey en-subtitle= kn-subtitle= en-abstract= kn-abstract=In integration of Turkey to the EU,the scope of regional programs has been transformed to reach the basic regional socio-economic standards of the Union. In this way, new cooperative regional programs have been applied in Turkey by the EU and Turkey. Therefore, some regional programs in Nomenclature of Territorial Units for Statistics（NUTS）level-2 regions have been examined in this study. In this point, the data of regional GDP per capita by sectors has been used to analyse sectoral disparities in terms of Gini index. To discuss and evaluate the future of the programs on regional disparities, related sector parameters of GDP per capita have been calculated by regression analysis through（balanced）panel data. The findings showed that there is a remarkable sectoral disparity among program regions, and the sector priorities of the programs are not sufficient to bring any long-term solution for the regional disparities. Finally, Turkey from regional and/or multiregional perspectives needs to reconsider the regional programs for decreasing the disparities as much as development ofthe regions. en-copyright= kn-copyright= en-aut-name=DincsoyEnver Erdinc en-aut-sei=Dincsoy en-aut-mei=Enver Erdinc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University, Graduate School of Natural Science and Technology affil-num=2 en-affil= kn-affil=Okayama University, Graduate School of Environmental Science and Technology en-keyword=Regional program kn-keyword=Regional program en-keyword=Sectoral GDP per capita kn-keyword=Sectoral GDP per capita en-keyword=Gini index kn-keyword=Gini index en-keyword=the EU kn-keyword=the EU en-keyword=Turkey kn-keyword=Turkey END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=390 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Construction of Argument Structure Analyzer Toward Searching Same Situations and Actions kn-title=類似した動作や状況を検索するための意味役割及び動詞語義付与システムの構築(第1回集合知シンポジウム〜言語処理が紡ぎ出す未来〜) en-subtitle= kn-subtitle= en-abstract=This manuscript proposes an argument structure analyzer that can identify verb meanings and semantic roles of their arguments from not only for sentences but compound nouns. The motivation of development of this analyzer is we need a tool to find the same or quasi-same situations, actions and changes in events. For this purpose various levels of paraphrases should be identified taking into account context, however, the proposed analyzer focus on providing lexicon-based paraphrasable relations i.e., matching "employ/use/utilize these tools" and "employment of these tools''. In this paper we clarify how we construct the modules of the analyzer, i.e., identification of idioms, deverbal-noun-argument identification in compound nouns, identification of content verbs, and identification of predicate verb semantics and their semantic roles on the basis of example based matching. The base data of verb meanings we use is a Japanese Verb Thesaurus build in our previous work and freely distributed. kn-abstract=本研究では類似した動作や状態を検索するための基礎技術として,動作表現の類似関係を付与する項構造付与システムを構築している.項構造とは動詞と名詞の係り関係まで含めて動作の共通部分を記述するもので,例えば「XがYを逮捕する」「Yを捕まえる」には概念を共通していることを示す.本研究ではすでに,4425語(7473語義)の動詞に対して動詞間の項構造関係をシソーラス形式で整理して公開している.そこでこのオントロジーを基に規則ベースの項構造付与システムの構築を行った.本報告では項構造付与に必要なサブタスクとして,慣用句同定,複合名詞内係関係同定,主動詞探索を取り上げ事例による語義決定法について述べる.また,現状での語義付与精度について簡単な評価実験を行う. en-copyright= kn-copyright= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name=竹内孔一 kn-aut-sei=竹内 kn-aut-mei=孔一 aut-affil-num=1 ORCID= en-aut-name=TsuchiyamaSuguru en-aut-sei=Tsuchiyama en-aut-mei=Suguru kn-aut-name=土山傑 kn-aut-sei=土山 kn-aut-mei=傑 aut-affil-num=2 ORCID= en-aut-name=MoriyaMasato en-aut-sei=Moriya en-aut-mei=Masato kn-aut-name=守屋将人 kn-aut-sei=守屋 kn-aut-mei=将人 aut-affil-num=3 ORCID= en-aut-name=MoriyasuYuuki en-aut-sei=Moriyasu en-aut-mei=Yuuki kn-aut-name=森安祐樹 kn-aut-sei=森安 kn-aut-mei=祐樹 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学工学部情報工学科 affil-num=3 en-affil= kn-affil=岡山大学工学部情報工学科 affil-num=4 en-affil= kn-affil=岡山大学工学部情報工学科 END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=234 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Bio-medical Term Extraction with Morpho-Syntactic Rules on Simple Rule Language kn-title=SRLを利用した規則ベースの感染症用語抽出 en-subtitle= kn-subtitle= en-abstract=Simple rule language, rule-based term extraction, bio-medical terms, Disease surveillance system Bio-medical term extraction is a key technology for a surveillance system of epidemic disease news from the Web. In the previous work we applied statistical learning model to extract terms from the Web site. The previous approach is good at extracting terms with high precision rates; however it is weak at extracting new terms that do not exist in the training data. Since we usually have new disease names a new term extraction approach with high coverage for unknown or low-frequent terms is needed. Recently, Simple rule Language (SRL), a rule-based word extraction language, is freely available. The SRL also has an developing environment called SRL editor. Thus we are constructing rules of bio-medical terms on the several language (such as English, Japanese, Thai and Vietnam) for the multilingual disease surveillance system. In this manuscript we confirm how we construct rules to extract Japanese bio-medical terms from Japanese news articles. kn-abstract=我々は感染症情報をWeb上から集めて提示するBioCasterシステムを構築している.感染症情報は各国のローカルニュースに速報が出ることが予測されることから英語のみならず日本語を含めたアジア言語での開発を進めている.核となる技術は感染症に関する用語を記事から見つける用語抽出であるが,既存の手法では学習データを利用した統計的学習モデルを利用して構築した.しかしながら,新たな病気など学習データに無い用語が現れた際うまく獲得できないことが予測されるため規則に基づく用語抽出システムの構築を行う.規則ベースで用語を抽出するシステムとしてSRL(Simple Rule Language)が公開されており,ユーザは語構成ならびに文脈を規則で記述することで用語を抽出できる.そこで本研究では感染症情報に必要な用語についてどのようにSRL上で定義できるかについて明らかにする. en-copyright= kn-copyright= en-aut-name=ShinnouTakashi en-aut-sei=Shinnou en-aut-mei=Takashi kn-aut-name=新納貴志 kn-aut-sei=新納 kn-aut-mei=貴志 aut-affil-num=1 ORCID= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name=竹内孔一 kn-aut-sei=竹内 kn-aut-mei=孔一 aut-affil-num=2 ORCID= en-aut-name=NigelCollier en-aut-sei=Nigel en-aut-mei=Collier kn-aut-name=ナイジェルコリアー kn-aut-sei=ナイジェル kn-aut-mei=コリアー aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学工学部情報工学科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil= kn-affil=国立情報学研究所 END start-ver=1.4 cd-journal=joma no-vol=110 cd-vols= no-issue=245 article-no= start-page=13 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Extraction of Verb Synonyms Using Graph-Based Clustering kn-title=グラフに基づくクラスタリングによる動詞類義語の獲得(自然言語の論理と感情) en-subtitle= kn-subtitle= en-abstract=This manuscript describes evaluation results of Kernel K-means clustering approach comparing with modified Aizawa's co-clustering approach for verb synonym extraction task. Kernel K-means approach is one of the state-of-the-art vector-based clustering method which can divide vector-spaces with non-linear boundary by incorporating Kernel method. Besides the mathematical framework of Kernel K-means can cover Spectral Graph Clustering. In this manuscript, however, we reveal Aizawa's co-clustering approach overcomes Kernel K-means on the verb synonym extraction task (bi-graph clustering) in Japanese. From this results we discuss that the equivalence between graph-vector space in Kernel K-means approach can be limited, and then Kernel K-means decease their accuracy in our verb synonym extraction. kn-abstract=本研究ではクラスタリングを利用して動詞の類義語を獲得する方法について検討している.先行研究において,同時に2つの要素のクラスタを考慮しながらクラスタリングする同時共起クラスタリングを適用して,ベクトルベースのクラスタリングより精度が高いことを示した.しかし,近年ベクトルベースのクラスタリングでKernel K-meansという非線形境界でクラスタリングするより高度な手法が提案された.そこで,本報告ではKernel K-means法を我々の動詞類語獲得に適用し,先行研究における同じデータで同時共起クラスタリングとの比較を行う.この結果からKernel K-meansでのグラフ-ベクトルの等価性には限界があり,本研究が利用する2部グラフの構造は直接反映できないこと,先行研究の同時共起クラスタリングの方が高い精度で類語を獲得できることを報告する. en-copyright= kn-copyright= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name=竹内孔一 kn-aut-sei=竹内 kn-aut-mei=孔一 aut-affil-num=1 ORCID= en-aut-name=TakahashiHideyuki en-aut-sei=Takahashi en-aut-mei=Hideyuki kn-aut-name=高橋秀幸 kn-aut-sei=高橋 kn-aut-mei=秀幸 aut-affil-num=2 ORCID= en-aut-name=KobayashiDaisuke en-aut-sei=Kobayashi en-aut-mei=Daisuke kn-aut-name=小林大介 kn-aut-sei=小林 kn-aut-mei=大介 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil= kn-affil=岡山大学工学部情報工学科 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=120 end-page=120 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境理工学部博士論文 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=119 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境理工学部研究受賞等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=81 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境物質工学科 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=45 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境管理工学科 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=33 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境デザイン工学科 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=18 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2012年度環境数理学科 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=1 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Management of Arable Land in Japan - An Analysis on Transition of Non-cultivated Arable Land - en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Japan, the number of full-time farm households had continued to decrease since the latter half of 20th century. The number of part-time households has been also decreasing remarkably in the last twenty years. Cultivated acreage also aligned with these tendencies and it has decreased. As a result, the farmland which is not cultivated increased and it may also grow into a social problem. Therefore, the present condition and future view of Japanese agriculture was elaborately examined in the study by analyzing the transition of non-cultivated arable lands from a historical perspective.

to tourists and local residents. Both tourists and local residents estimate that the landscape ofBittchu-Kokubunji is wonderful, and it has several images such as historical, quiet, and old-fashioned, etc. AlthoughBittchu-Kokubunji is one of the famous tourist resorts in Okayama prefecture, there are quite few tourists compared with the degree of notability. Almost all tourists' age was 50 or more. As more active sightseeing activities, the number of times of holding events, such as an announcement of traditional performing arts, lighting of a five-storied pagoda, photograph or a sketching convention, needs to be increased. An attractive tourist resort should be created by the cooperation of local residents and administration. en-copyright= kn-copyright= en-aut-name=MizutaTomoya en-aut-sei=Mizuta en-aut-mei=Tomoya kn-aut-name=水田智也 kn-aut-sei=水田 kn-aut-mei=智也 aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=(株)三浦工業 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境管理工学科景観管理学分野 en-keyword=Landscape kn-keyword=Landscape en-keyword=Sightseeing kn-keyword=Sightseeing en-keyword=Local residents kn-keyword=Local residents en-keyword=Bittchu-Kokubunji kn-keyword=Bittchu-Kokubunji END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=7 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Survey Study of University Students’ Awareness on Social Contribution and Regional Cooperation kn-title=大学生の社会貢献・地域連携に対する意識 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, competition among universities has a whole new face, and emphasis is given toward interdependence and interactive evolution between universities and regions. From this social perspective, universities should contribute to regional development by serving the regional society using results of intellectual work, and it is necessary for universities to accomplish social contribution and regional cooperation strategically. One of the most important parts in strategic planning is that students participate in activities for social contribution and regional cooperation. This paper presents a survey of the university students’ awareness on social contribution and regional cooperation using several statistical methods and attempts to find factors which affect activities for social contribution and regional cooperation using logistic regression analysis. en-copyright= kn-copyright= en-aut-name=NaMyungjin en-aut-sei=Na en-aut-mei=Myungjin kn-aut-name=羅明振 kn-aut-sei=羅 kn-aut-mei=明振 aut-affil-num=1 ORCID= en-aut-name=ArakiMasaru en-aut-sei=Araki en-aut-mei=Masaru kn-aut-name=荒木勝 kn-aut-sei=荒木 kn-aut-mei=勝 aut-affil-num=2 ORCID= en-aut-name=KuriharaKoji en-aut-sei=Kurihara en-aut-mei=Koji kn-aut-name=栗原考次 kn-aut-sei=栗原 kn-aut-mei=考次 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学大学院環境学研究科 en-keyword=University students’ awareness kn-keyword=University students’ awareness en-keyword=social contribution and regional cooperation kn-keyword=social contribution and regional cooperation en-keyword=volunteer activities kn-keyword=volunteer activities en-keyword=exploratory factor analysis kn-keyword=exploratory factor analysis en-keyword=logistic regression analysis kn-keyword=logistic regression analysis END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Basic Reproductive Ratio for Epdiemic Models (Review) kn-title=感染症数理モデルの再生産数(レビュー) en-subtitle= kn-subtitle= en-abstract= kn-abstract=We review some fundamental results on the basic reproductive ratio of models in epidemiology following several documents.

The wet ball milling of the simulated waste slag powder was performed using a ball mill pot and balls in air for 10 - 100 h at room temperature with the rotational speed fixed at 200 rpm. The fractions of CaO and Fe2O3 in the specimens obtained by wet-ball-milling the simulated waste slag powder decreased, that of SiO2 increased, and those of Al2O3 and Na2O hardly changed. These specimens contained 0.1 – 0.8mass% ZrO2. Appropriate solution and time for wet ball milling were 300 ml distilled water and 20 h, respectively. When the wet ball milling of the simulated waste slag powder was performed twice, the fractions of CaO, Al2O3 and Fe2O3 in the specimen obtained after repeated wet ball milling decreased, those of SiO2 and ZrO2 increased and that of Na2O hardly changed in comparison with those in the specimen wet-ball-milled once. The insoluble end product obtained by soaking the specimen wet-ball-milled once in 6M HCl for 20 hours was composed of 98.5mass% SiO2 and 0.6mass% or less other oxides and is usable as glass material. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name=紅野安彦 kn-aut-sei=紅野 kn-aut-mei=安彦 aut-affil-num=2 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境管理センター affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Inorganic slag kn-keyword=Inorganic slag en-keyword=EDTA kn-keyword=EDTA en-keyword=Wet ball milling kn-keyword=Wet ball milling en-keyword=Recycling kn-keyword=Recycling END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=126 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Research on the Effect of a Teacher Training Program for Freshmen,“The Visit to Their Old High School” kn-title=「母校訪問」を核とする全学教職課程初年次プログラムの成果と課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=岡山大学は全学の教職課程を担う「教師教育開発センター」を平成22年度に創設し、学部の枠を超えた教員養成教育の質保証に取り組んでいる。教育実習事前事後指導や教育実習ならびに教職実践演習（平成25年度から実施）等を中心とする「全学教職コア・カリキュラム」の企画・運営だけではなく、これらの科目の教育成果とその課題を検証し、FD的視点に基づくカリキュラム開発と改善とを進めている。「母校訪問」とは、教育学部以外の学生（文学部、法学部、経済学部、理学部、工学部、環境理工学部、農学部、マッチングプログラムコース）のうち、改正後の教育職員免許法が適用される平成22 年度以降入学生（現１、２年生）を対象に、センターが独自に開発した１年次生対象のプログラムである。本稿ではその成果と課題の検証を通して、いわゆる「開放制」と「大学における教員養成」の原則に基づいた教員養成教育の可能性を検討する。 en-copyright= kn-copyright= en-aut-name=GotoDaisuke en-aut-sei=Goto en-aut-mei=Daisuke kn-aut-name=後藤大輔 kn-aut-sei=後藤 kn-aut-mei=大輔 aut-affil-num=1 ORCID= en-aut-name=TakahataHiroshi en-aut-sei=Takahata en-aut-mei=Hiroshi kn-aut-name=髙旗浩志 kn-aut-sei=髙旗 kn-aut-mei=浩志 aut-affil-num=2 ORCID= en-aut-name=KashidaTakeshi en-aut-sei=Kashida en-aut-mei=Takeshi kn-aut-name=樫田健志 kn-aut-sei=樫田 kn-aut-mei=健志 aut-affil-num=3 ORCID= en-aut-name=MishimaTomotaka en-aut-sei=Mishima en-aut-mei=Tomotaka kn-aut-name=三島知剛 kn-aut-sei=三島 kn-aut-mei=知剛 aut-affil-num=4 ORCID= en-aut-name=EgiEiji en-aut-sei=Egi en-aut-mei=Eiji kn-aut-name=江木英二 kn-aut-sei=江木 kn-aut-mei=英二 aut-affil-num=5 ORCID= en-aut-name=SodaKayoko en-aut-sei=Soda en-aut-mei=Kayoko kn-aut-name=曽田佳代子 kn-aut-sei=曽田 kn-aut-mei=佳代子 aut-affil-num=6 ORCID= en-aut-name=TakahashiKayo en-aut-sei=Takahashi en-aut-mei=Kayo kn-aut-name=高橋香代 kn-aut-sei=高橋 kn-aut-mei=香代 aut-affil-num=7 ORCID= en-aut-name=KagaMasaru en-aut-sei=Kaga en-aut-mei=Masaru kn-aut-name=加賀勝 kn-aut-sei=加賀 kn-aut-mei=勝 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=2 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=3 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=4 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=5 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=6 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=7 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=8 en-affil= kn-affil=岡山大学大学院教育学研究科 en-keyword=母校訪問 kn-keyword=母校訪問 en-keyword=全学教職課程初年次プログラム kn-keyword=全学教職課程初年次プログラム en-keyword=開放制教員養成教育の質保証 kn-keyword=開放制教員養成教育の質保証 en-keyword=FD kn-keyword=FD END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Contents en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Faculty of Engineering, Okayama University en-aut-sei=Faculty of Engineering, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=2 article-no= start-page=51 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=200203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulatory Role for Complement Receptors (CD21/CD35) in the Recombination Activating Gene Expression in Mouse Peripheral B Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=A population of peripheral B cells have been shown to express recombination activating gene products, RAG-1 and RAG-2, which are considered to be involved in revising the B cell antigen receptor (BCR) in the periphery. BCR engagement has been reported to turn off RAG expression in peripheral B cells, whereas the same treatment has an opposite effect in immature B cells in the bone marrow. In contrast to receptor editing that is involved in the removal of autoreactivity in immature B cells, it has been shown that secondary V(D)J rearrangement in peripheral B cells, termed receptor revision, contributes to affinity maturation of antibodies. Here, we show that RAG-2 expression in murine splenic B cells was abrogated by the coligation of BCR with complement receptors (CD21/CD35) much more efficiently than by the engagement of BCR alone. On the other hand, the same coligation augmented proliferation of anti-CD40-stimulated B cells. Consistent with these observations, RAG-2 expression was lower in the draining lymph nodes of the quasi-monoclonal mice when they were immunized with a high-affinity antigen than with a low-affinity one. These findings suggest a crucial role for CD21/CD35 in directing the conservation or the revision of BCRs in peripheral B cells. en-copyright= kn-copyright= en-aut-name=HikidaMasaki en-aut-sei=Hikida en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakayamaYasunori en-aut-sei=Nakayama en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanayamaNaoki en-aut-sei=Kanayama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhmoriHitoshi en-aut-sei=Ohmori en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=2 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=3 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=4 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=5 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=1-2 article-no= start-page=91 end-page=96 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Generation of IgM and IgG1 monoclonal antibodies with identical variable regions: comparison of avidity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Generally, IgM antibodies (Abs) produced in a primary immune response show lower affinity for an inducing antigen (Ag) compared with the corresponding IgG Abs that are major switched isotypes formed in the secondary response. An IgM molecule is a pentamer with 10 Ag-binding sites that will contribute to an increase of avidity for an Ag. To estimate the contribution of the pentameric structure to the avidity of an IgM Ab, we generated IgM and IgG1 monoclonal Abs (mAbs) with identical V regions that are specific for 4-hydroxy-3-nitrophenylacetyl (NP) by in vitro class switching of B cells followed by the cell fusion with a mouse myeloma cell line. Compared with an anti-NP IgG1 mAb, the corresponding IgM mAb showed much higher avidity for NP-conjugated bovine serum albumin, which was drastically reduced after being dissociated into monomers. en-copyright= kn-copyright= en-aut-name=KanayamaNaoki en-aut-sei=Kanayama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamakoshiKimi en-aut-sei=Yamakoshi en-aut-mei=Kimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KiyomiMasaaki en-aut-sei=Kiyomi en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhmoriHitoshi en-aut-sei=Ohmori en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=2 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=3 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=4 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University affil-num=5 en-affil= kn-affil=Department of Bioscience and Biotechnology, Faculty of Engineering, Okayama University END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=1371 article-no= start-page=1195 end-page=1198 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=200911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chemical recycling of municipal waste slag by using phase separation en-subtitle= kn-subtitle= en-abstract= kn-abstract=A chemical recycling method by using phase separation was applied to municipal waste slags. Glasses were prepared from incineration ash and ash-melted slag, where B(2)O(3) was added to promote phase separation. The glasses were heat-treated at temperatures higher than their glass transition temperatures, and they were soaked in hydrochloric acid, leaching CaO, Fe(2)O(3), K(2)O, and S. Transparent and colorless solids containing ca. 80 mass% of SiO(2) were successfully obtained as residues. It was suggested that phase separation took place not in the heat-treatment but in the vitrification process, and further characterizations are however required to investigate the phenomena at microscopic levels in the recycling processes. en-copyright= kn-copyright= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaYutaro en-aut-sei=Kuroda en-aut-mei=Yutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Municipal waste slag kn-keyword=Municipal waste slag en-keyword=Waste recycling kn-keyword=Waste recycling en-keyword=Chemical recycling kn-keyword=Chemical recycling en-keyword=Glass kn-keyword=Glass END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=1379 article-no= start-page=603 end-page=607 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phase separation of borosilicate glass containing sulfur en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 10Na(2)S·30B(2)O(3)·60SiO(2) (mol %) glass was prepared, and the changes in glass structure and chemical state of sulfur caused by phase separation were investigated. In the as-prepared and heat-treated glasses, sulfur was present as S(2)− anion and polysulfide S(2)− and S(3)− anions, and Si–S and B–S bonds were not confirmed. A phase separation by spinodal decomposition was observed after heat-treatment, where sulfur was preferentially distributed to borate-rich phase. Even after the phase separation, formation of non-bridging oxygen was not recognized. The preferential distribution of sulfur anions in the present glass was explainable on the basis of the change in population of sodium ions, which compensated the negatively-charged sulfur anions. en-copyright= kn-copyright= en-aut-name=SaikiKeiji en-aut-sei=Saiki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Borosilicate glass kn-keyword=Borosilicate glass en-keyword=Chemical state of sulfur kn-keyword=Chemical state of sulfur en-keyword=Glass structure kn-keyword=Glass structure END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=1-2 suppl article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Forecasts on date and degree of prevalence of Japanese Encephalitis (Epidemiological study on Japanese Encephalitis, 66) kn-title=日本脳炎の流行時期及び流行規模の予測について （日本脳炎の疫学的研究 66） en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order to forecast the median date or the incidence rate in the prevalence of Japanese Encephalitis (JE) in Okayama Prefecture, the authors took the following factors into consideration: for deciding the median date, climatic elements, date showing immunological positivity of hemoagglutination inhibition reaction (called HI Reaction, in short) on 50 per cent number of swine and the latitude and longitude as geographical elements; and for deciding the incidence rate, the logarithm of Cule Tritaneorhychus (Ct) number and also climatic factors.

However, comparing the model with Penman equation showed that AA model doesn’t properly evaluate evapotranspiration from urban moisture area. In urban area, Actual evaporation from water calculated by AA model(E) are much less than that by Penman equation(Epo). Multiple regression analysis using estimation results indicates that the difference between the models is due to the difference of the sensitivity to vapor pressure deficit between the models. To improve this problem, modification coefficient k, defined as k=a･albedo+b, is suggested. Regression coefficients a, b are determined as satisfying k=Epo/E for water and k=1 for urban surface. By using this coefficient k, evaporation from water is nearly equal to value estimated by Penman equation, while evaporation from urban surface is changeless. en-copyright= kn-copyright= en-aut-name=NakamichiTakeshi en-aut-sei=Nakamichi en-aut-mei=Takeshi kn-aut-name=中道丈史 kn-aut-sei=中道 kn-aut-mei=丈史 aut-affil-num=1 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=2 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部 en-keyword=Complementary relationship kn-keyword=Complementary relationship en-keyword=Actual evapotranspiration kn-keyword=Actual evapotranspiration en-keyword=Potential evapotranspiration kn-keyword=Potential evapotranspiration en-keyword=Water budget kn-keyword=Water budget END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=7 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Changes and Problems of Commercial Activities in terms of the Questionnaire Survey in Omote-cho as the Central Shopping Street in Okayama City kn-title=岡山市の商業活動の推移と課題―中心商店街、表町地区の分析を中心にして― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study mainly studied some properties of retail stores on the central shopping streets in Okayama City while looking back on the transition of the commerce.

The charm of the central shopping streets has decreased relatively in Okayama City due to the advancement of a large-scale stores and the location competition of convenience stores. The number of empty stores has increased and the amount of the pedestrian traffic, the value of sales, and the number of retail stores have shown the decreasing tendency in eight commercial blocs in Omote-cho. Therefore, the unique features in Omote-cho should be polished while esteeming the history and the culture.

In this study, we validate the effecte of the ddollar cost averaging investment method by Monte Carlo simulation. en-copyright= kn-copyright= en-aut-name=ToujiMasayuki en-aut-sei=Touji en-aut-mei=Masayuki kn-aut-name=田路正幸 kn-aut-sei=田路 kn-aut-mei=正幸 aut-affil-num=1 ORCID= en-aut-name=FuedaKaoru en-aut-sei=Fueda en-aut-mei=Kaoru kn-aut-name=笛田薫 kn-aut-sei=笛田 kn-aut-mei=薫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部 en-keyword=Dollar cost averaging kn-keyword=Dollar cost averaging en-keyword=investment kn-keyword=investment en-keyword=Monte Carlo simulation kn-keyword=Monte Carlo simulation en-keyword=Stock price index kn-keyword=Stock price index END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Contents en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=Faculty of Engineering, Okayama University kn-aut-sei=Faculty of Engineering, Okayama University kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=26 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=200912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Material recycling of inorganic sludge by wet ball milling kn-title=湿式ボールミル法を用いた無機性汚泥の再資源化技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The possibility of material recycling of inorgamic sludge by wet ball milling with distrilled water and an ethylenediaminetetraacetic acid disodium salt dehydrate (EDTA・2Na・2H(2)O)reagent was investigated. The inorganic sludge consisted of 14.1mass% of the heat-treated sludge obtained after drying and heat treatment, 20.1mass% of active carbon, and 65.9mass% of water. The wet ball milling of the heat-treated sludge was performed using a ball pot and balls in air for 40 h at room temperature with the rotational speed fixed at 200rpm. The fractions of Mn, Fe, Ni, Cu, and Zr in the specimens obtained by wet-ball-milling the heat-treated sludge decreased and those of Si and Al increased. Appropriate content of distilled water and weight of the heat-treated sludge for wet ball milling were 150-250 ml and 4.5 g or less, respectively. When the wet ball milling of the heat-treated sludge was perfomed twice,the fractions of Mn, Fe, Ni, Cu, and Zr in the specimen obtained after repeated wet ball milling remarkably decreased and that of Si increased in comparison with those in the specimens wet-ball-milled once. This suggests that the repeat of wet ball milling of the heat-treated sludge leads to a colorless specimen without colored ions such as Mn, Fe, Ni, and Cu. en-copyright= kn-copyright=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=The umu-test, which can detect genotoxic activites of a wide variety of environmental carcinogens and mutagenes, was carried out with samples from several sewage treatment processes. We applied the umu-test to raw sewage and treated effluent from two points of view, one is to evaluate a treatment process and the other is to identify the genotoxic substances. The original strain of umu-test, Salmonella typhimurium TA1535/pSK1002 can detect nonspecific genotoxicity, on the other hand, by using S. typhimurium NM2009 of the umu-test highly sensitive to aromatic amines, genotoxicity related to aromatic amines is measured. The result showed that genotoxic substances which have the polycyclic aromatic amino structures in the sewage remained after biological treatment. Tow-step HPLC fractionation followed by MS analysis to identify the genotoxic substances was applied to samples to detect mutagenic and carcinogenic heterocyclic amines. The concentration of Trp-P-1 and Trp-P-2 determined in the effluent caluculated from HPLC-UV analysis were on the order of 10(-5) mg/L. Because of the possibility of the reuse of wastewater in urban areas, the need for the investigation of the safety of the treated water from the sewage treatment plants was suggested, in order to evaluate strategies for advanced treatment, if necessary. en-copyright= kn-copyright= en-aut-name=MohriShino en-aut-sei=Mohri en-aut-mei=Shino kn-aut-name=毛利紫乃 kn-aut-sei=毛利 kn-aut-mei=紫乃 aut-affil-num=1 ORCID= en-aut-name=OnoYoshiro en-aut-sei=Ono en-aut-mei=Yoshiro kn-aut-name=小野芳朗 kn-aut-sei=小野 kn-aut-mei=芳朗 aut-affil-num=2 ORCID= en-aut-name=KawaraOsami en-aut-sei=Kawara en-aut-mei=Osami kn-aut-name=河原長美 kn-aut-sei=河原 kn-aut-mei=長美 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境デザイン工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境デザイン工学科 END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue= article-no= start-page=5 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=200108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Engineering issues of Degradation of Waste Plastics into Fuel Oil for Recycling Society kn-title=循環型社会構築に向けての廃プラスチック油化リサイクル技術開発の課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The rate of increase of plastic waste has been exceeded the rate of increase of plastic production during the period of 1975-1998. The development of technologies for resource reutilization of waste materials will not only be based on the waste-conversion-to-resource techniques but also the development of techniques for the effective collection, sizing, separation and sorting of the waste, and usage and transportation of the products from waste will be necessary. The treatment of waste materials must not be limited only to the scale-up of the treatment plants. Considering the population density and nature of locality, construction of small-scale plant for intermediate treatment will be essential. Even after repeated reutilization and resourceconversion of waste material the generation of ultimate refuse can not be avoided. Accepting this fact, formulation of a strategy for a progressive society with "Less Emission" will be necessary. For this purpose, arrangements of treatment facilities for the ultimate refuse will be essential. Among them, there is an urgent need for the development of technology for the treatment of halogen containing ultimate refuse. en-copyright= kn-copyright= en-aut-name=SakataYusaku en-aut-sei=Sakata

The purpose of this study is to develop a measuring system for subsurface contamination in which a so-called FDR (Frequency Domain Refiectometry) and FDR-V (with Vector network analyzer) system was employed to measure the salinity and oil contaminant. This FDR and FDR-V method is a coaxial probe method, which allows the measurement of the dielectric. The experimental study indicates the possibility in measuring both the contaminant concentration and volumetric moisture content. In addition, the method for obtaining the effective porosity using this equipment was shown. Concretely, the sensor was inserted in the ground, and the liquid in which the dielectric constant differed on the water in the circumference was injected, and the method for obtaining the effective porosity from the change of the dielectric constant was proposed. en-copyright= kn-copyright= en-aut-name=NishigakiMakoto en-aut-sei=Nishigaki en-aut-mei=Makoto kn-aut-name=西垣誠 kn-aut-sei=西垣 kn-aut-mei=誠 aut-affil-num=1 ORCID= en-aut-name=KomatsuMitsuru en-aut-sei=Komatsu en-aut-mei=Mitsuru kn-aut-name=小松満 kn-aut-sei=小松 kn-aut-mei=満 aut-affil-num=2 ORCID= en-aut-name=KimMan-il en-aut-sei=Kim en-aut-mei=Man-il kn-aut-name=金萬鎰 kn-aut-sei=金 kn-aut-mei=萬鎰 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=Dielectric constant kn-keyword=Dielectric constant en-keyword=Contamination kn-keyword=Contamination en-keyword=Frequency Domain Refiectometry kn-keyword=Frequency Domain Refiectometry en-keyword=In-situ kn-keyword=In-situ en-keyword=Effective porosity kn-keyword=Effective porosity END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=2 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=200308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=微生物農薬による害虫の防除と環境保全 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakaiHiroshi en-aut-sei=Sakai en-aut-mei=Hiroshi kn-aut-name=酒井裕 kn-aut-sei=酒井 kn-aut-mei=裕 aut-affil-num=1 ORCID= en-aut-name=YamagiwaMasashi en-aut-sei=Yamagiwa en-aut-mei=Masashi kn-aut-name=山際雅詩 kn-aut-sei=山際 kn-aut-mei=雅詩 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学工学部生物機能工学科 affil-num=2 en-affil= kn-affil=岡山大学工学部生物機能工学科 END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=17 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of biodegradability for polyethylene glycol via numerical simulation kn-title=数値シミュレーションによるポリエチレングリコール生分解性解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We examined the biodegradability of polyethylene glycol by analyzing gel permeation chromatography patterns, which were obtained before and after cultivation of a microbial consortium E-1 in culture media containing polyethylene glycol as its sole carbon source. We solved an inverse problem of the initial value problem, which consists of an exogenous depolymerization model and the initial weight distribution, in order to determine an oxidation rate, for which the solution of the initial value problem also satisfies the final condition. Given the oxidation rate, we simulated the transition of the weight distribution solving the initial value problem. We interpret the result that reflects a physical significance of the molecular weight on the oxidation rate, and reach a conclusion concerning the role of the membrane transport in exogenous depolymerization processes. en-copyright= kn-copyright= en-aut-name=WatanabeMasaji en-aut-sei=Watanabe en-aut-mei=Masaji kn-aut-name=渡辺雅二 kn-aut-sei=渡辺 kn-aut-mei=雅二 aut-affil-num=1 ORCID= en-aut-name=KawaiFusako en-aut-sei=Kawai en-aut-mei=Fusako kn-aut-name=河合富佐子 kn-aut-sei=河合 kn-aut-mei=富佐子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 affil-num=2 en-affil= kn-affil=岡山大学資源生物科学研究所 en-keyword=biodegradation kn-keyword=biodegradation en-keyword=polyethylene glycol kn-keyword=polyethylene glycol en-keyword=exogenous depolymerization kn-keyword=exogenous depolymerization en-keyword=mathematical model kn-keyword=mathematical model en-keyword=numerical simulation kn-keyword=numerical simulation END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=13 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Treatment of Chlorinated Compounds by Solvent Sublation kn-title=溶媒浮選法による有機塩素化合物の処理 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Removal of chlorinated compound from an aqueous solution has been studied using solvent sublation. Solvent sublation is one among the several adsorptive bubble separation techniques wherein a hydrophobic compound is levitated on a bubble surface to the top of an aqueous column where they encounter a solvent layer to which the material is transferred as the bubbles move through the solvent layer. A model for the removal mechanism of the chlorinated compounds from aqueous solution was constructed. Removal rate constants for air stripping and for solvent sublation respectively are possible to calculate from the model's equations. The experiments were conducted on a laboratory batch scale using the 0.1m inner diameter bubble column. Bubbles were generated from the perforated plate. The chlorinated compound is dichrolomethane. The solvent layer is kerosine. Dichrolometane was removed at high efficiency by solvent sublation as compared with conventional air stripping, The removal rate constant from the model was compared with experimental result. The mass adsorbed on the bubble surface of 8 types of chlorinated compounds were assumed by the measurements of surface tension. The removal rate constants of these chlorinated compounds, for solvent sublation or for air stripping, are calculated from model equations using the linear adsorption constant. en-copyright= kn-copyright= en-aut-name=KasenoSatoru en-aut-sei=Kaseno en-aut-mei=Satoru kn-aut-name=加瀬野悟 kn-aut-sei=加瀬野 kn-aut-mei=悟 aut-affil-num=1 ORCID= en-aut-name=MiyaharaToshiro en-aut-sei=Miyahara en-aut-mei=Toshiro kn-aut-name=宮原敏郎 kn-aut-sei=宮原 kn-aut-mei=敏郎 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学保健環境センター環境安全部門 affil-num=2 en-affil= kn-affil=岡山理科大学工学部応用化学科 en-keyword=Solvent Sublation kn-keyword=Solvent Sublation en-keyword=air stripping kn-keyword=air stripping en-keyword=Chlorinated compounds kn-keyword=Chlorinated compounds END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue= article-no= start-page=11 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Material recycling of blast furnace slag by phase separation of glass kn-title=ガラスの分相現象を利用した高炉水砕スラグの再資源化技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A novel recycling process of blast furnace slag was developed in order to obtain colorless silica－rich solids by using phase separation of borosilicate glass. B(2)O(3) was added to blast furnace slag to promote the phase separation. The slag glasses were heat-treated above glass transition temperatures. The slag glass prepared from blast furnace slag gelled after the heat treatment and the subsequent three types of acid treatment. The ratios of SiO(2) component in the gels were 40 - 60mass%. On the other hand, phase separation was observed on the surface of the slag glasses prepared from pre-treated slag by 2.5N HCI after the heat treatment. After soaking in acid, they did not gel and changed to insoluble colorless solids. According to compositional analyses, it was found that the insoluble colorless solids contained 70 - 90mass% SiO(2). No colored ions such as Cr, Mn, and Fe were confirmed in the remaining insolubles by optical absorption measurement. Therefore, the colorless silica-rich solids were successfully obtained in the present process. The end products obtained in the present process are expected as material of glass. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=MikamiSyuuhei en-aut-sei=Mikami en-aut-mei=Syuuhei kn-aut-name=三上修平 kn-aut-sei=三上 kn-aut-mei=修平 aut-affil-num=2 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=3 ORCID= en-aut-name=MiuraToshinari en-aut-sei=Miura en-aut-mei=Toshinari kn-aut-name=三浦嘉也 kn-aut-sei=三浦 kn-aut-mei=嘉也 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学保健環境センター環境安全部門 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=4 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Blast furnace slag kn-keyword=Blast furnace slag en-keyword=Recycling kn-keyword=Recycling en-keyword=Colorless silica-rich solids kn-keyword=Colorless silica-rich solids en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Glass kn-keyword=Glass END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=15 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=19941130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Note on the Electronic Structure of C(60) Molecule en-subtitle= kn-subtitle= en-abstract= kn-abstract=A molecular orbital approach to the electronic structure of C(60) molecule is formulated on the basis of optimized bond orbital model and the stability of the truncated icosahedron structure is examined. en-copyright= kn-copyright= en-aut-name=TotsujiChieko en-aut-sei=Totsuji en-aut-mei=Chieko kn-aut-name=東辻千枝子 kn-aut-sei=東辻 kn-aut-mei=千枝子 aut-affil-num=1 ORCID= en-aut-name=MatsubaraTakeo en-aut-sei=Matsubara en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObuchiMasumi en-aut-sei=Obuchi en-aut-mei=Masumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=2 en-affil= kn-affil=Okayama University of Science affil-num=3 en-affil= kn-affil=Okayama University of Science END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=7 end-page=14 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=19941130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electronic States in Semiconductor Quantum Dot with Fluctuating Interfaces en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effects of interface fluctuations on the electronic states in semiconductor quantum dots are analyzed on the basis of numerical solutions for ground state wave functions and energy eigenvalues.

The fungi cultivated by APC or MSLC secreted a greater number of different proteins/enzymes in larger quantities compared with fungi cultivated by SFC, particularly when DPY medium was used. In particular, the amounts of protease secreted by fungi cultivated via MSLC or APC were much greater compared with SFC. When mCD medium was used, α-amylase activity was barely detectable in all cultures while the activity was detected in MSLC and APC in a quantity that was several times higher than that in SFC using DPY medium. SDS-PAGE analysis and N-terminal amino acid sequences confirmed 6 proteins in the culture supernatants when DPY medium was used. Among these proteins oryzin (an alkaline protease) and α-amylase were detected at much higher levels in APC and MSLC compared with SFC, which was consistent with the measured activity of the secreted enzymes. However, when mCD medium was used, only oryzin was detected in significant amounts in MSLC and APC. Microarray analyses of the fungi cultivated by SFC, APC or MSLC using either mCD or DPY media indicated that the gene transcriptional profile of the MSLC sample was similar to that of the APC sample but different from that of the SFC sample. When mCD medium was used, most of the genes that were up-regulated 10-folds or greater in the MSLC sample relative to the SFC sample were unknown or predicted proteins. Transcription of the oryzin gene was only slightly up-regulated in the MSLC sample while transcription of the α-amylase gene was slightly down-regulated. On the other hand, when DPY medium was used, many known genes including the oryzin gene were up-regulated in the MSLC sample versus the SFC sample. en-copyright= kn-copyright= en-aut-name=ImanakaHiroyuki en-aut-sei=Imanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaSoukichi en-aut-sei=Tanaka en-aut-mei=Soukichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FengBin en-aut-sei=Feng en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanishiKazuhiro en-aut-sei=Nakanishi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=69 end-page=72 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ecient Squaring Algorithm for Xate Pairing with Freeman Curve en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, pairing–based cryptographies have attracted much attention.

In detail, the order has two large prime factors such as the modulus of RSA cryptography. The method is based on the property that the order of the target pairing–friendly curve is given by a polynomial as r(X) of degree 2 with respect to the integer variable X. When the bit size of the prime factors is about 500 bits, the proposed method averagely takes about 15 minutes on Core 2 Quad (2.66Hz) for generating one. en-copyright= kn-copyright= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorikawaYoshitaka en-aut-sei=Morikawa en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=50 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High Accuracy Homography Computation without Iterations en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present highly accurate least-squares (LS) alternatives to the theoretically optimal maximum likelihood (ML) estimator for homographies between two images. Unlike ML, our estimators are non-iterative and yield solutions even in the presence of large noise. By rigorous error analysis, we derive a “hyperaccurate” estimator which is unbiased up to second order noise terms. Then, we introduce a computational simplification, which we call “Taubin approximation”, without incurring a loss in accuracy. We experimentally demonstrate that our estimators have accuracy surpassing the traditional LS estimator and comparable to the ML estimator. en-copyright= kn-copyright= en-aut-name=KanataniKenichi en-aut-sei=Kanatani en-aut-mei=Kenichi kn-aut-name=金谷健一 kn-aut-sei=金谷 kn-aut-mei=健一 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=NiitsumaHirotaka kn-aut-sei=Niitsuma kn-aut-mei=Hirotaka aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=RangrajanPrasanna kn-aut-sei=Rangrajan kn-aut-mei=Prasanna aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=2 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=3 en-affil= kn-affil=Department of Electrical Engineering Southern Methodist University END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=42 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hyperaccurate Ellipse Fitting without Iterations en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a new method for fitting an ellipse to a point sequence extracted from images. It is widely known that the best fit is obtained by maximum likelihood. However, it requires iterations, which may not converge in the presence of large noise. Our approach is algebraic distance minimization; no iterations are required. Exploiting the fact that the solution depends on the way the scale is normalized, we analyze the accuracy to high order error terms with the scale normalization weight unspecified and determine it so that the bias is zero up to the second order. We demonstrate by experiments that our method is superior to the Taubin method, also algebraic and known to be highly accurate. en-copyright= kn-copyright= en-aut-name=KanataniKenichi en-aut-sei=Kanatani en-aut-mei=Kenichi kn-aut-name=金谷健一 kn-aut-sei=金谷 kn-aut-mei=健一 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=RangrajanPrasanna kn-aut-sei=Rangrajan kn-aut-mei=Prasanna aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=2 en-affil= kn-affil=Department of Electrical Engineering Southern Methodist University END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=32 end-page=41 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimization without Search: Constraint Satisfaction by Orthogonal Projection with Applications to Multiview Triangulation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present an alternative approach to what we call the “standard optimization”, which minimizes a cost function by searching a parameter space. Instead, the input is “orthogonally projected” in the joint input space onto the manifold defined by the “consistency constraint”, which demands that any minimal subset of observations produce the same result. This approach avoids many difficulties encountered in the standard optimization. As typical examples, we apply it to line fitting and multiview triangulation. The latter produces a new algorithm far more efficient than existing methods. We also discuss optimality of our approach. en-copyright= kn-copyright= en-aut-name=KanataniKenichi en-aut-sei=Kanatani en-aut-mei=Kenichi kn-aut-name=金谷健一 kn-aut-sei=金谷 kn-aut-mei=健一 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=NiitsumaHirotaka kn-aut-sei=Niitsuma kn-aut-mei=Hirotaka aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=SugayaYasuyuki kn-aut-sei=Sugaya kn-aut-mei=Yasuyuki aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=2 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=3 en-affil= kn-affil=Department of Information and Computer Sciences Toyohashi University of Technology END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=24 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improved Multistage Learning for Multibody Motion Segmentation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present an improved version of the MSL method of Sugaya and Kanatani for multibody motion segmentation. We replace their initial segmentation based on heuristic clustering by an analytical computation based on GPCA, fitting two 2-D affine spaces in 3-D by the Taubin method. This initial segmentation alone can segment most of the motions in natural scenes fairly correctly, and the result is successively optimized by the EM algorithm in 3-D, 5-D, and 7-D. Using simulated and real videos, we demonstrate that our method outperforms the previous MSL and other existing methods. We also illustrate its mechanism by our visualization technique. en-copyright= kn-copyright= en-aut-name=KanataniKenichi en-aut-sei=Kanatani en-aut-mei=Kenichi kn-aut-name=金谷健一 kn-aut-sei=金谷 kn-aut-mei=健一 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=SugayaYasuyuki kn-aut-sei=Sugaya kn-aut-mei=Yasuyuki aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Computer Science Okayama University affil-num=2 en-affil= kn-affil=Department of Information and Computer Sciences Toyohashi University of Technology END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=13 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unified Computation of Strict Maximum Likelihood for Geometric Fitting en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new numerical scheme is presented for computing strict maximum likelihood (ML) of geometric fitting problems having an implicit constraint.

Our approach is illustrated by ellipse fitting and fundamental matrix computation. Our method also encompasses optimal correction, computing, e.g., perpendiculars to an ellipse and triangulating stereo images.
