Outline of Final Research Achievements

Gunma prefecture is famous for a strong wind in winter. This study examined how a natural feature influence clothes by observation images which were recorded with camera. The air temperature and Wind Chill Index were effective in order to assess the relationship between a natural feature and the rate of clothes. Subjects were asked to send pictures of their clothes by e-mail. As a result, it was found that the young people today tend to wear clothing which is light and warm.
We measured thermoregulation in conditions created by the combination of wind and rain. Experiment were conducted outside at the temperature standing at around 24℃ and 30℃. Two conditions of clothing were employed: T (T-shirt & shorts) and TP (T-shirt, shorts, and waterproof clothing). Subjects were exposed to 2 kinds of wind (weak 1.0m/s, strong 4.3m/s). Mean skin temperature indicated remarkable decrease in the condition in which rain was added, in comparison with the condition in which only wind was employed.
