Polio epidemics in the USA during the 1940s and 1950s were among the most feared diseases of the 20th century. Sister Elizabeth Kenny and President Franklin Roosevelt both made key contributions to modern rehabilitation medicine, leading to the promotion of global progress made by the International Society of Physical and Rehabilitation Medicine a half century later. Dr. Miland Knapp at the University of Minnesota was also considered a pioneer in modern rehabilitation medicine, as he supported the Kenny treatment method for acute polio patients. The Kenny method was subsequently widely adopted in the USA.

2006年から2012年までの7年間,山梨県北部の乙女高原のホンドテンMartes melampus melampusの食性を糞分析法により調べた(n=756).秋と冬のベリー(多肉果実,出現頻度80%以上),夏の昆虫類(40~80%),冬と春の哺乳類(60~80%)が特徴的だった.哺乳類ではネズミ類が高頻度(30~50%)で,ニホンジカCervus nipponは10%未満だった.昆虫類ではセミの幼虫(46.7%)とカマドウマ類(10~40%)が高頻度であった.ベリーの種子が非常に高頻度に出現したが,そのうちサルナシActinidia arguta(33.6%)とヤマブドウVitis coignetiae(19.5%)の種子は秋から冬にとくに頻度が高かった.出現した種子10種3属のうちの約半数(5種1属)は林縁種であり,その頻度は種子全体の79.9%に達し,調査地の群落面積を考えると強く林縁種に偏っていた.ホンドテンは森林性とされるが,果実利用という点では林内ではなく林縁に偏った利用をすると考えられる.シカの出現に年変動は認められず,2006年時点ですでに利用が始まっていたと判断された.

The aim of the present study was to investigate the differences in kinematics between 2 types of motor strategy for expert dart throwing. We divided 8 experts into 2 groups based on the motor strategies they had demonstrated in a previous study (Nasu et al., 2014): group A were experts who had a longer time window in which a release could result in hitting the bull's eye, and group B were experts who had a shorter time window but greatly reduced their timing error. Each subject performed 60 dart throws, aiming at the center of the dart board (bull's eye). The movement of the dart, index finger, and joint motion of the upper extremity were captured using a motion capture system with 7 cameras (480 Hz, Oqus300, Qualysis Inc.). We compared the shape of the hand trajectory and joint kinematics between the groups. We found that experts in group A demonstrated a smaller shoulder angle (lower elbow height) and a larger angle of elbow flexion through forward swing than those in group B. These differences affected the time window that led to a successful throw, i.e. the time for which the mutually complementary relationship among the release parameters (especially the relationship between velocity and direction of motion) was maintained. These results may be useful as basic data to help clarify how throwing accuracy can be improved in several sports.

This study aims definition of complex phenomena arising under screw thread fastening process and deep understanding of past relevant knowledge. So far, authors have been studied on screw fastening mechanism of a clamped body with M10 bolt-nut by using 3D elastoplastic FE analysis. In this paper, more precise analytical model is developed and the bolt-nut fastening process is calculated. Consequently, following matters were revealed. (a) Greatly complicated deformation of bolt-nut joined threads area under contacting was clarified qualitatively. Supporting contribution percentages of each thread to axial load was calculated; especially the first thread of joining screw thread supported about 31% of axial force. (b) Spring constant of bolt-nut or clamped part calculated by the present FEM was well accorded with some theoretical equations within 7% error. Contribution of elongation of each region with the bolt also agreed with these equations. Most of all, the validity of Sawa-Maruyama's equation was showed. (c) During fastening process, development of stress or strain at the bolted joint was visualized compatibly alongside of past knowledge and information.

Tremendous developments in science and technology have brought prosperity and an affluent lifestyle to mankind, but scientific and technological progress has also generated social issues related to the environment, security, ethics, and socioeconomic activities. Under these circumstances, a Science, Technology, and Society (STS) education that emphasizes the teaching of scientific and technological developments in their cultural, economic, social, and political contexts is required in order to cultivate human resources capable of making decisions about how to address these issues. In this study, we developed “nocobon,” a game-based teaching material for thinking on STS issues from various perspectives. “Nocobon” is a detective card game that can be played by a group of three to six people. The results of its prototype test for high school students suggest that players could acquire new knowledge and learn to think from different perspectives on STS issues through unlocking the mysteries in a series of “nocobon” cards. The results also indicate that “nocobon” could be a simple and convenient teaching material from the viewpoint of the time management.

Although the number of foreign visitors to Japan has increased remarkably in recent years, many licensed guides have not been usefully employed. One of the main reasons for this is that there is a problem with the system of producing new work-ready guides in Japan. Currently, the Japanese government only conducts the national examination, and informs successful applicants of a file of associations of licensed guides, which offer several days of basic training to a very limited number of new guides. Most new guides have no chance to take practical training to become a professional guide, and travel companies do not employ them. After examining guide systems in 54 countries and regions, I found that the following points are essential to a system which produces new work-ready guides: (1) A system which issues a license after several years of training, following a final examination (2) A license renewal system to secure the quality of a guide A system with these elements must be employed immediately in Japan in order to increase the number of a high-quality qualified guides, and to meet the strong demand from the inbound tourism industry.

Objective: The present study aimed to determine the generation and behavior of airborne particles that could carry microorganisms around the area of the feet while walking in a bio-clean operating room.Methods: Four surgical staff members performed four walking patterns comprising combinations of the following: independently or as a group, and entering or exiting the operating room.Results: Fine particle visualization and laser particle counts revealed large numbers of airborne particles on shoes, the hems of gowns, and the floor regardless of the walking pattern. Numerous airborne particles were generated by followers who walked in groups and even more particles were brought to the level of the operating table by groups compared to solitary walkers.Conclusion: Surgical staff should be aware of transferring airborne particles from non-sterile areas to reduce the incidence of contamination by airborne bacteria in bio-clean rooms.

Among the oxidation products of edible fats and oils, lipid hydroperoxides and the low-molecular-weight compounds containing short-chain aldehydes such as 4-hydroxynonenal are absorbed from the intestinal wall and carried into the internal organs with oral administration to rodents. Oral intake of lipid hydroperoxides or the low-molecular-weight compounds causes significant cytotoxic damage to the lymphoid tissues. The DNA synthesis of thymocytes is remarkably depressed and lymphocyte necrosis is observed in the thymus and intestinal Peyer's patches. In these cases, the mitogenic response to concanavalin A of splenocytes is increased. With long-term (90 d) feeding of slightly autoxidized soybean oil (peroxide value ; 150 meq/kg) in mice, the same symptoms as those mentioned above are observed. These findings indicate that oral intake of rancid oils give significant effects on immunocompetent cells and causes depression of the DNA synthesis of thymocytes, which would be one of the major cause for impairing immunocompetent systems in animals.

Background:N-terminal pro-B-type natriuretic peptide (NT-proBNP) is known to increase in heart failure patients. Given that no reports have described the association between NT-proBNP and chronic kidney disease (CKD) incidence in Asian populations, we investigated this association in the Japanese population.Methods and Results:We followed up 867 participants without CKD from the general population of Ohasama, Japan. We defined CKD as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2and/or proteinuria. In accordance with previous studies, the participants were classified into 4 groups according to NT-proBNP level (<30.0, 30.0–54.9, 55.0–124.9, and ≥125.0 pg/mL). The Cox model was applied to assess adjusted hazard ratios (HR) for CKD incidence after full adjustment including baseline eGFR. Participant mean age was 59.1 years, and 587 (67.7%) were women. During the mean follow-up period of 9.7 years, 177 participants developed CKD. When the group with NT-proBNP <30.0 pg/mL was used as the reference, adjusted HR for CKD incidence in the 30.0–54.9, 55.0–124.9, and ≥125.0 pg/mL groups were 1.34 (95% CI: 0.90–2.01), 1.25 (95% CI: 0.81–1.92), and 1.83 (95% CI: 1.05–3.18), respectively.Conclusions:NT-proBNP can be significantly predictive for CKD incidence in Asian populations.
