体重計測より測定した成人男女における水分出納の結果について, 季節(環境温度)別に発汗と不感蒸泄による水分損失量(ΣS)と身体活動量(エネルギ消費量)との相関を求めた.この回帰式からに季節別・身体活動レベル別にΣSを算出し, さらに排便・排尿による水分損失量(ΣU)を加えて身体活動レベル毎の水分摂取基準を季節別に示した. また生活現場応用を目的として, 冬季の身体活動レベルが低い(I)時のΣSを基準として, その差分を季節・身体活動レベル別に求めた. その結果, 標準体重を有する普通の活動レベル(II)である日本人では, 冬季の低い活動レベル(I)に比べて夏季では男性1.1kg, 女性0.9kg程度多く水分を摂取する等, 現代日本人(成人男女)における具体的な水分摂取基準を作成・提示できた。

The purpose of this study is to examine the optimum fermentation period of clay by analyzing the technical properties of daubing motion among several kinds of clay. An expert wall craftsman (right-handed male, 56 years old, 28 years of work experience) and a non-expert (right-handed male, 37 years old, 6 years of work experience) daubed on the wall using 4 kinds of clay with different fermentation period (1-day, 1-, 2-, 3-week). The shape-maintenance property of clay was evaluated by slump test. The motion of daubing was measured using a three-dimensional motion analysis system. The slump value under 1- and 2-week clay condition was higher than 1-day and 3-week. Under 1-day clay condition, speed and acceleration of the right hand (vertical direction) were lower than other conditions. Moreover, daubing motion of the expert was hardly influenced on clay condition compared with the non-expert. These results suggest that the optimum fermentation period of clay is 1 or 2 weeks.

Kyoto bow is the Japanese traditional bow which made form 100% natural materials such as bamboo, woods and so on. Kyoto bow consists of three different parts and they were glued together, so that Kyoto bow can be regarded as hybrid adhesive composite structure. The characteristics of Kyoto bow very much depend on the materials and adhesive. The purpose of this study is to investigate the effect of the structural materials of bow on muscle activity during drawing the bow. Three kinds of bow were used in this study; 1) typical carbon bow, 2) Kyoto bows which were produced with normal bamboo, or 3) heated bamboo. The deformations of bow and muscle activities were measured during drawing the bows by using the motion capture and the electromyogram. As a result, advantage of a Kyoto bow and muscle activity during the drawing the bow were clarified.
