Japanese Society of Biometeorology(JSB) issued "The guideline of heat disorders prevention in daily life ver. 1" on 2008. It includes specific attentions for individuals in 4 grades by WBGT level and strength of daily activity standard. In 2011, JSB revised ver. 1 and published "Urgent proposal for heat disorders under the saving electricity". Now, ver. 2 is preparing towards summer 2012.

The purpose of the present study was to ascertain whether increase in step frequency at a given velocity during running reduces the lower extremity loading variables, which is associated with tibial stress fracture in runner. We hypothesized that the lower extremity loading variables at a given speed would be minimized at around + 15% f step. 10 male subjects were asked to run at 2.5 m/s on a treadmill-mounted force platform. 5 step frequencies were controlled using a metronome: the preferred, below preferred (15 and 30%) and above preferred (+ 15 and + 30%). From the vertical ground reaction force, we measured following lower extremity loading variables; vertical impact peak (VIP), vertical instantaneous loading rate (VILR) and vertical average loading rate (VALR). We found that there were significant differences in lower extremity loading variables among 5 step frequency conditions. Furthermore, quadratic regression analyses revealed that the minimum loading variable frequencies were 17.25, 17.55, and 18.07% of preferred step frequency for VIP, VILR and VIAR, respectively. Thus, adopting a step frequency greater than one's preferred may be practical in reducing the risk of developing a tibial stress fracture by decreasing lower extremity loading variables. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of this study is to investigate how and to what extent modern people's life is affected by cell phones, which have been rapidly penetrating into the people's individual life. Surveys were conducted by questionnaires to Japanese college students (288 females and 54 males, ages 18 to 21) about their dependency on cell phones and habits of using them. The result was analyzed by the KJ method extracting the typical feelings about cell phones. Forty typical feelings were rated by 5 levels and analyzed in relation to the using years and the frequency per day. About 20% of the students used cell phones more than 30 times a day and for more than 3 hours in average per day. A decisive point concerning the users' dependency on cell phones seemed to exist between the daily use of 30 times and 40 times. At the same time, female students appeared more dependent on cell phones. Those feelings were classified into 6 groups; being 'dependent' on cell phones, regarding cell phones as 'important', 'necessary', 'convenient', just a 'method' of communication, and 'troublesome'. The percentages of those who felt cell phones as convenient, a method, important and necessary were high both in males and females. The dependence on cell phones seemed to be affirmative in both sexes, but males consistently felt cell phones as methods, whereas females tended to be more dependent on them from psychological reasons. Consequently, there were observed some differences between males and females in their use and feelings to cell phones.

As contemporary higher education information environments transform, this study highlights the significance of university identity and college identity that are formed continuously through independent activities of the students. Based on these discussions, the present study proposes a practical media environment design which facilitates the processes of organizational identity formation based on a continuous and cyclical model.

A questionnaire survey of high school students regarding self-consciousness and their opinions and behaviors towards cosmetics has shown that the more the students feel self-acceptance, the more they expect that makeup will cause exhilarated conditions or feelings such as a "change in appearance" or "impression management". It has also shown that the less the positive aspects of self-consciousness such as "fulfillment sentiment" for boys or "self-actualization" and "having a good relationship with parents" for girls become, the more they feel as if they cannot do anything without makeup. The factor analysis of their attitudes towards cosmetics has shown that a "change in appearance" or "impression management" and "necessity for makeup" belong to the same factor for boys while to different factors for girls. Further, by using multiple regression analysis, opinions towards cosmetics have been estimated from their self-consciousness and behaviors, and the obtained relationships have been compared for boys and girls: high school boys are more affected by self-consciousness than by behaviors towards cosmetics while high school girls are less affected. © 2016 Jpn.
