| Abstract | The aim of this study is to evaluate how metallic artifacts in the lumbar spine can affect images obtained from magnetic resonance (MR) sequences. We performed a phantom experiment by scanning an agar containing an orthopedic metallic implant using 64-channel multidetector row computed tomography (CT) and a 3-tesla MR unit. We compared the reproducibility in each measurement, enlargement or reduction ratio of the CT and MR measurements, and signal deviation in each voxel from the control. The reproducibility on CT and multiacquisition variable-resonance image combination selective (MAVRIC SL) was good, but that on the other MR sequences showed either fixed bias or proportional bias. The reduction ratios of the distance between the nails were significantly smaller in MAVRIC SL than in the other MR sequences after CT measurements (p<0.001, respectively). MAVRIC SL was able to reduce the metallic artifact, permitting observation of the tissue surrounding the metal with good reproducibility. |

| Abstract | The forced swim test (FST) induces immobility in mice. Low-dose (high-dose-rate) X-irradiation inhibits FSTinduced immobility in mice due to its antioxidative function. We evaluated the effects of low-dose γ-irradiation at a low-dose-rate on the FST-induced depletion of antioxidants in mouse organs. Mice received whole-body low-dose-rate (0.6 or 3.0 mGy/h) of low-dose γ-irradiation for 1 week, followed by daily FSTs (5 days). The immobility rate on day 2 compared to day 1 was significantly lower in the 3.0 mGy/h irradiated mice than in sham irradiated mice. The FST significantly decreased the catalase (CAT) activity and total glutathione (t-GSH) content in the brain and kidney, respectively. The superoxide dismutase (SOD) activity and t-GSH content in the liver of the 3.0 mGy/h irradiated mice were significantly lower than those of the non-FST-treated mice. The CAT activity in the lungs of mice exposed to 3.0 mGy/h γ-irradiation was higher than that of non-FST treated mice and mice treated with FST. However, no significant differences were observed in the levels of these antioxidant markers between the sham and irradiated groups except for the CAT activity in lungs. These findings suggest that the effects of low-dose-rate and low-dose γ-irradiation on FST are highly organ-dependent. |

| Abstract | This retrospective study sought to elucidate the incidence rates of roof impaction (RI) and marginal impaction (MI) and radiological and clinical outcomes of open reduction and internal fixation (ORIF) for RI and MI in geriatric acetabular fractures. The cases of 68 patients aged ≥ 65 years (mean 71 years) treated with ORIF were analyzed. MI was present in 12 fractures (67%) and an RI of the weight-bearing surface was present in 24 (46%) of the potential fracture types. Regarding the reduction quality, 54% of the reductions were graded as anatomical, 37% as imperfect, and 9% as poor. In the clinical evaluations of the 45 patients who had > 1-year follow-up (follow-up rate: 66.2%), 18% were graded as excellent, 53% as good, 16% as fair, and 13% as poor. An anatomic reduction was strongly associated with good or excellent clinical and radiological outcomes. CT was superior to radiographs for detecting the residual displacement postoperatively. Postoperative deep infection occurred in four patients. Three patients (6.7%) underwent a total hip arthroplasty conversion due to secondary osteoarthritis of the hip. We recommend ORIF as the preferred surgical treatment option for displaced acetabular fractures in elderly patients. |

| Abstract | Lactoferrin (Lf) is an iron-binding glycoprotein mainly found in exocrine secretions and the secondary granules of neutrophils. In the central nervous system (CNS), expression of the Lf protein has been reported in the lesions of some neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis, as well as in the aged brain. Lf is primarily considered an iron chelator, protecting cells from potentially toxic iron or iron-requiring microorganisms. Other biological functions of Lf include immunomodulation and transcriptional regulation. However, the roles of Lf in the CNS have yet to be fully clarified. In this study, we raised an antiserum against mouse Lf and investigated the immunohistochemical localization of Lf-like immunoreactivity (Lf-LI) throughout the CNS of adult mice. Lf-LI was found in some neuronal populations throughout the CNS. Intense labeling was found in neurons in the olfactory systems, hypothalamic nuclei, entorhinal cortex, and a variety of brainstem nuclei. This study provides detailed information on the Lf-LI distribution in the CNS, and the findings should promote further understanding of both the physiological and pathological significance of Lf in the CNS. |

| Title Alternative | Information and communication technology equipment and services for remote monitoring and health management: Survey of services and their classification for use in home care nursing |
| FullText URL | interdisciplinary_1_47_63.pdf |

| Abstract | This study aims to improve the quality of home nursing care for the elderly. The report presents web-based information about devices and services for remote monitoring and health management using information and communication technology and about how they can improve home care nursing station efficiency in Japan. The search terms "elderly people," "watch over," and "service," plus "sensor" were used to narrow the search. After repeating the search using a chained search for materials and links extracted from those search results, services for home care stations particularly addressing the remote monitoring of elderly people were selected and extracted. Early detection of abnormalities for support by home health nurse responsibilities for observing the general condition of the patient was chosen as the main evaluation index of usefulness. The contractor and service cost were secondary evaluation axes. Results show 9 information communication devices and services for real-time monitoring of the elderly persons’ vital signs in real time for 24 hr, 2 of which are highly useful for early detection of abnormalities and subsequent response. Results suggest that other services might be more useful, depending on how they are used, and that general-purpose services with minimum functions and low cost of introduction and maintenance can provide more opportunities for utilization. Providing these services on a BtoBtoC model and responding to patients’ medical needs can supplement home care nursing station work, increase human resource and time efficiencies, and give patients "the feeling that a nurse is always at their bedside,” even when far away. |

| Title Alternative | Consideration about recognition of factors causing lack of confirmation in the nursing scene |
| FullText URL | interdisciplinary_1_29_45.pdf |
| Author | Zuo, Wanxin| Hyodo, Yoshimi| Tanaka, Tomoko| Gofuku, Akio| |
| Abstract | In the work process of nurses with high risk, it is very urgent to take countermeasures against the “lack of confirmation” of the main factors. Therefore, the purpose of this study is to clarify the details of the factors leading to the lack of confirmation, grasp the number of near misses, and to explore what kind of factors the individual characteristics of the nurse who acts as a stopper. We recruited 500 nurses on the Web and asked about the frequency of near misses due to lack of confirmation, the awareness of the causes of lack of confirmation, self-evaluation of stoppers, and the reasons why near misses did not lead to accidents. As a result, three factors were extracted regarding the recognition of the factors of lack of confirmation: "lack of consciousness", "inability to concentrate", and "lack of knowledge / experience". Three factors were extracted for self-evaluation of stopper characteristics: "awareness," "verification," and "cautiousness". In order to reduce the lack of confirmation, it is necessary to secure and allocate appropriate personnel and create an environment where treatment can be concentrated. Nurses should also raise knowledge and the awareness of the importance of confirmation. In addition, it is necessary to improve the clinical judgment of new nurses in order to prevent near misses. And it is thought that new nurses will become more confident by accumulating experience and affirming their abilities from their superiors, seniors and colleagues. |

| Title Alternative | Business Case: Tourism Campaigning Process of the Shimanami Kaido Expressway over the Setouchi Inner Sea in Japan |
| FullText URL | interdisciplinary_1_21_28.pdf |
| Author | Nakao, Hikari| Fujii, Daiji| |
| Abstract | The Shimanami Kaido Expressway was visioned as a national project in the early 1970s after two tragic maritime accidents in the Setouchi Inner Sea. Since the express way connecting several islands between Hiroshima and Ehime prefecture was placed in use in 1999, it has always been a valuable means of transportation for islanders and commuters to date. In addition, with the proactive efforts made by local governments, such as Imabari City, Onomichi City, let alone with the central and prefectural governments, it has come to be acknowledged to be a sanctuary for sport cyclists. Eventually, it attracts attentions from all over Japan as a successful benchmark for both businesspeople as well as policy makers who are interested in destination management practices as part of promotion policies of reginal economies. This eventual success, however, had not been envisioned as such for a long time since the commencement of its public usage. It would rather seem that the plan had taken on its shape after a long period of many twists and turns. Furthermore, while local governments have been closely cooperating with different types of stakeholders including the actual islanders to promote the development plans, their ways of thinking are still far from unanimous. The purpose of this article is to provide business and policy students with materials that draw lessons for viewing lengthy socioeconomic processes like this case which eventually converted a nation-level, large-scale infrastructure development plan into an area-specific destination management project. |

| Title Alternative | Rolling stockpile of medical supplies for pandemic preparedness: modeling and simulation |
| FullText URL | interdisciplinary_1_17_20.pdf |
| Author | Morita, Mizuki| |
| Abstract | When a global pandemic of infectious diseases occurs, demand for medical supplies such as masks, disinfectants, and personal protective equipment will exceed the production capacity in normal times, consequently leading to serious shortages. Stockpiling is necessary to prepare for such situations. However, because pandemics are infrequent and might occur at any time, stockpile freshness is an important concern. As described in this paper, a “rolling stockpile” of medical supplies is proposed to prevent the medical supply stockpile from becoming too old. A formulation of a model and simulations based on it is presented. Results demonstrate that the method is applicable to the design of warehouses for rolling stockpiles, monitoring stockpile depletion during emergencies, and monitoring the process of recovery from emergencies. |

| Abstract | Medial meniscus posterior root tears (MMPRTs) have recently attracted considerable interest in orthopedics. To date, no in vivo human study has investigated suture translation changes in repaired MMPRTs with different degrees of knee flexion. This study examined suture translation at various degrees of knee flexion in 30 patients undergoing medial meniscus posterior root repair using the modified Mason-Allen suture technique between August 2016 and September 2017. Intraoperatively, sutures were provisionally fixed to an isometric positioner at the tibial site of the desired meniscal attachment, and the suture translation was measured at 0°, 30°, 60°, and 90° of knee flexion. The results showed significant increases in mean suture translation at the knee flexion positions from 0° to 30°, 30° to 60°, and 60° to 90° (p<0.01 for all). Our findings indicate that surgeons should carefully assess the degree of knee flexion at the moment when the meniscus is refixed by surgical sutures. |
