The purpose of this study is to investigate the relationship between the width of a foot at the metacarpophalangeal (MP) joint and the circumference around the MP joint. The width and circumference data provide reasonable estimates of the three dimensional foot shape and therefore may be used by a reliable and inexpensive a shoes-selection system. The results showed that (1) there was a high correlation (r > 0.8) between the foot widths and circumferences and (2) errors in estimating the circumferences from foot widths were as small as the difference between the sizes of the right and left foot.

There are established teaching methods in classical ballet. However, many of the classical ballet teachers in Japan do not learn these teaching methods. Additionally, official license for certified teacher do not exist in Japan. Therefore, this study discussed how to develop education systems for teachers in classical ballet focusing on license system in Japan. Japanese ballet dancers were interviewed. As a result, many of the dancers hove been feeling the situation as a problem. They also think it is difficult to establish license system in Japan due to the reasons such as deciding effective issuing organization, setting standards and levels, and managing the balance with existing non-licensed teachers. The Japan Sports Association issues license for coaches in many other sports. Pros and cons which have been indicated in those license systems have many in common with what the dancers have concerned if it was applied for classical ballet. If the requirement increased, it would be beneficial to examine the pros and cons of license systems in other sports when establishing license system in classical ballet.

In this paper I try to reveal how the experience of a huge earthquake influences on disaster-prevention consciousness, for which I held interaction activities between junior high school students of Nara with a little experience of an earthquake and those of Sendai with an experience of Great East Japan Earthquake. And I examined how the students of each area accepted an earthquake. The result will show us guidance of the future disaster prevention education.
