Objectives: This study evaluated prior sports participation and training frequency during elementary to high school and their association with acute and overuse injuries in Japanese college students currently majoring in physical education. Methods: This retrospective study included 292 students who completed questionnaires that assessed their type of sport participation (single sport or multiple sports), training frequency (number of days per week), and injury history (acute and overuse) during the elementary, junior high, and high school periods. Results: In total, 47.9% (95% confidence interval [CI]: 38.2–57.7) of elementary school-aged athletes played multiple sports; this decreased to 22.3% (95% CI: 14.1–30.4) in junior high school and 5.5% (95% CI: 1.0–9.9) in high school. There was a significant difference in the training frequency between those who had overuse injuries and not in elementary (p < 0.05), and junior high school (p < 0.05). Conclusions: The results of this study suggest that participating in multiple sports through junior high school may lead to improved sports levels (i.e., participation in higher levels of competition). In addition, appropriate management of training frequency may help reduce the incidence of overuse injuries.

Japanese Corporate Law after the Arrival of Black Ship: Controlling Shareholder’s Fiduciary Duty

Kana Morimura 한국경영법률학회 2009 經營法律 Vol.19 No.3

회사활동이 글로벌화하는 과정에서 일본은 2005년에 회사법제에 대한 큰 폭의 개혁을 단행하였다. 즉 일본에서는 신회사법이 2005년 6월 29일 국회를 통과하고, 2005년 7월 26일 공포되었다. 신회사법은 종래 각 법률에 산재해 있던 회사관련법규정을 하나로 통합한 것으로서 기존의 상법 제2편의 회사부분을 상법으로부터 분리하고, 이를 상법특례법 및 유한회사법 등과 합하여 단행법으로 한 것이다. 신회사법은 형식과 실질 양면에서 대대적인 개정을 단행한 것이다. 일본의 새로운 회사법은 현대적인 기업인수합병제도를 규정하고 있다. 특히 회사지배거래에서 다수파의 횡포로부터 소수주주를 보호하는 것이 문제가 되고 있다. 그런데 일본 신회사법은 소소주주를 보호하는 메커니즘으로서 지배주주의 충실의무를 도입하지 아니하였다. 회사와 주주를 위하여 행동하여야 하는 이사와는 달리, 지배주주는 주주로서의 자신의 이익을 추구하게 된다. 그런데 이사에게 적용되는 그러한 의무는 지배주주에게는 자동적으로 적용되지 않는다. 이러한 측면이 이사와 주주의 충실의무를 해석함에 있어서 서로 상이한 결과를 초래하게 된다. 본 논문에서는 일본에서의 지배주주의 충실의무 도입론을 다룬다. 구체적으로는 제2장에서 일본에서의 지배주주의 충실의무가 왜 인정받지 못하였는가 하는 점에서의 역사적인 배경을 검토한다. 제3장에서는 일본이 모델로 삼을만한, 지배주주의 충실의무론이 미국에서 어떻게 기능하고 있는지를 검토한다. 제4장에서는 회사의 행동에 대한 주주의 책임에 대한 일본에서의 현재의 논의를 소개한다. 그리고 제5장에서는 지배주주의 충실의무의 필요성을 주장하고 일본 신회사법제에 대한 제언을 한다.

For Japanese, the European style is not a traditional way of clothing, but the Japanese youth now adapt the European style as granted. As the cultural background is different from that in Europe, the Japanese youth never consider the social significance of the European style clothes, and design without any traditional restriction. In these 150 years, the Japanese have been unconsciously balancing their mentality between the European rational logics and traditional ambiguity. In other words, we are always under psychological pressure by clothing, and in consequence create the European-style clothes with the Japanese sense of value, leading to the birth of Japan cool. The Japan cool is in the sense a resistance against the rational civilization based on the European logics. This fact explains why the phenomena of the so-called Japonism appear periodically at the time of the industry revolution. The report aims to analyze the influence of the psychological stress and individual character on the choice of color in our daily clothing. A human character is another factor to be considered in the analysis. The results indicate the color characteristics depend on the psychological stress in some extent when the total stress is considered. However, Y (yellow) shows no stress dependence because the color variation could be less available in the market. The subjects were found to cocoon themselves to be less distinguished in public by the psychological stress. The Japan cool is thought to have emerged from the private clothes of the "black-list" type and the "calm" type under the psychological stress.

A shrinking population, low birthrate, and aging society are problems Japanese society is currently facing. The population of Japan began decreasing in 2005 and It is estimated the population will shrink to 70% of its current level by 2055. there are disparities between sparsely populated mountainous regions and urban areas in terms of the social capital that forms the basis of everyday life (infrastructure such as public facilities, roads, sewers, telecommunications; and medical, health, and welfare systems). Our objective was to clarify issues related to the living environments of older adults people. Methods: Surveys were conducted using questionnaires and through semistructured interviews. (1) Questionnaire survey: Subjects: 333 households, 627 people age 20 or older, a collection rate of 37.3%. (2) Semi-structured interview The result of this study is most of participant wanted to continue living in the district but the living environment are lacking, most of resident is single person households and the 80% of resident are regularly going to hospital. 50% of them in personal interview said that the transportation infrastructure and medical service is inconvenient. The main reason of the inconvenient is high frequent of going to hospital and difficulty finding support. In order to support the older adults to live their home in rural community, it is necessary to advance developing human resources and develop the community support system in order to provide the end of life care in the home.

The Role of Home-Based Care Managers in Japan

Kana Kageyama,Mitsu Ono,Yuki Sawada 한국노인복지학회 2014 International Journal of Welfare for the Aged Vol.31 No.-

Surveys were conducted to study the role and function of care managers (CMs) in Japan` s long-term care insurance system by examining work hours and subjective evaluations. Between October and December 2011, we used a self-report time study method with 745 CMs in 308 home-based care management agencies and received responses from 373 people in 153 businesses (50.1% response rate). By performing cluster analysis based on the values of necessity, burden, and achievement in the subjective evaluations of the CMs` duties, we were able to classify 16 duties into two groups; cluster 1 included conclusion of contracts, in-service/seminars, staff supervision, patients` rights advocacy, complaint resolution, direct/nursing care activities, quality improvement activities and facility administration-related activities, and cluster 2 included pre-admission consultations, assessment, care planning activities, team management, consultation, cooperation with the community, indirect care activities, and other. Cluster 2 had a greater rate of occurrence than cluster 1, and more time was spent on these duties. In addition, necessity was higher in cluster 2 than in cluster 1, although burden and achievement were lower. The duties in cluster 2 are consistent with the role of CMs required under the long-term care insurance system. Eleven years of practice have passed since the birth of care management along with the long-term care insurance system; CMs are recognizing the necessity of these duties as realities confronting them become apparent, and the CMs` role has been clarified. The duty with the highest necessity and achievement was patients` rights advocacy. Complaint resolution had the highest burden. In terms of the CMs` role, the possibility of further proactive involvement in patients` rights advocacy and improving the ability to cope with complaint resolution could lead to a reduced burden on CMs.

HARMONIC MAPPINGS RELATED TO FUNCTIONS WITH BOUNDED BOUNDARY ROTATION AND NORM OF THE PRE-SCHWARZIAN DERIVATIVE

Kanas, Stanis lawa,Klimek-Smet, Dominika Korean Mathematical Society 2014 대한수학회보 Vol.51 No.3

Let ${\mathcal{S}}^0_{\mathcal{H}}$ be the class of normalized univalent harmonic mappings in the unit disk. A subclass ${\mathcal{V}}^{\mathcal{H}}(k)$ of ${\mathcal{S}}^0_{\mathcal{H}}$, whose analytic part is function with bounded boundary rotation, is introduced. Some bounds for functionals, specially harmonic pre-Schwarzian derivative, described in ${\mathcal{V}}^{\mathcal{H}}(k)$ are given.

Proficiency, Use of Context and Non-Native Speech Perception in Noise Performance

Kanae Nishi 한국청각언어재활학회 2018 Audiology and Speech Research Vol.14 No.3

Purpose: The present study evaluated a novel method of quantifying relative use of bottom-up and top-down processing when perceiving speech in challenging listening conditions. Methods: One-hundred seven normal-hearing adults participated as listeners. Fortyseven were Spanish-speaking, second-language learners of English (L2) and 60 were monolingual speakers of English. Using adaptive procedure, signal-to-noise ratios required for 70%-correct recognition of words and sentences (SNR70) were obtained for all listeners. Individual listeners were statistically classified as “native-like” or “non-native” based on the sentence and word SNR70. Results: Despite their native-like performance in quiet, only half of the L2 listeners’ SNR70 values were “native-like”, whereas the remaining half L2 listeners required more favorable SNR70. Interestingly, although there was no notable difference in language background among the “nonnative”L2 listeners, half of them required more favorable SNR70 for sentences than for words, suggesting inability to use sentence context as effectively as the remaining “non-native” or “native-like” L2 listeners. Conclusion: The results show that the present method may be useful in identifying the shortcomings in listening strategies individual second-language learners use. Such information can possibly serve as a guide to choose exercises and/or training to alleviate difficulty they experience in challenging listening conditions, which may be possibly applicable to other listener populations.

C6, a new monoclonal antibody, reacts with the follicle-associated epithelium of calf ileal Peyer’s patches

Kana Tozaki,Junpei KIMURA,Nobuyuki Ryu,Testuo Nasu,Anton Pernthaner,Wayne R. Hein,Masahiro Yasuda 대한수의학회 2013 JOURNAL OF VETERINARY SCIENCE Vol.14 No.1

The follicle-associated epithelium (FAE) of Peyer’s patches (PPs) contains M cells that are important for reducing mucosal immune responses by transporting antigens into the underlying lymphoid tissue. We generated a monoclonal antibody (C6) that reacted with the FAE of calf ileal PPs, and analyzed the characteristics of C6 using immunohistochemistry and Western blotting. FAE of the ileal PP was stained with C6 during both late fetal developmental and postnatal stages. Neither the villous epithelial cell nor intestinal crypt basal cells were stained at any developmental stage. During the prenatal stages, FAE of the jejunal PP was C6-negative. However, a few C6-positive cells were distributed diffusely in some FAE of the jejunal PPs during the postnatal stages. The protein molecular weight of the antigen recognized by C6 was approximately 45 kDa. These data show that C6 is useful for identifying the FAE in ileal PPs and further suggest that differentiation of the FAE in these areas is independent of external antigens.
