项目摘要

We obtained the following findings in this research by the some creative techniques developed in the physio-anthropological field.1. Fatty subjects had smaller changes in skin temperature (TィイD2skィエD2) at the trunk and larger changes in peripheral TィイD2skィエD2 than lean subjects under both hot (37 ゜C) to cool (17 ゜C) and cool to hot conditions.2. TィイD2skィエD2 of subjects from the warm district (Kyushu) was higher than that from the cold district (Hokkaido and Tohoku) in a hot environment (40゜C). However, changes in TィイD2skィエD2 during the experiment showed higher value in the subjects from the cold district.3. There were significant correlations between increases in thermal sensation and in α2 band of electroencephalogram (EEG) during thermal stimuli applied to palm, and between increases in thermal comfort and in β1 band of EEG. Both increase in thermal sensation and decrease in thermal comfort showed significant correlations with increase in brain blood flow.4. Increase in rectal temperature of children were smaller than that of young adults during immersion of their legs in a hot water bath (42゜C) in a hot environment (30゜C). It was suggested that children regulate their body temperature mainly through a dry heat loss in a hot environment.5. Thermal responses to a hot (35゜C) and a cold (5゜C) environment were different between Japanese and Korean females wearing T-shirt and short pants, however, the way of responses to each thermal stress was affected by whether wearing Kimono or Hanbok in each Japanese and Korean.6. The ratio of body surface area to body weight was estimated from the physique or body type of several population groups, and the regression equation between the ratio and the mean air temperature of their resident places was calculated. Japanese males and females are found to be completely contained in this relation.

在这项研究中，我们通过在生理人类学领域发展的一些创造性的技术获得了以下发现。结果：1.无论是在热(37゜C)到冷(17゜C)和冷到热的条件下，肥胖受试者躯干皮肤温度(TィイD2skィエD2)的变化较小，而外周TィイD2skィエD2的变化较大。在高温环境下，温暖地区(九州)受试者TィイD2skィエD2高于寒冷地区(北海道和东北)受试者(40゜C)。而TィイD2skィエD2在实验过程中的变化在寒冷地区的受试者中表现出较高的数值。热刺激手掌时，热感觉的增加与脑电α-2频段的增加、热舒适度的增加与脑电的β-1频段之间存在显著的相关性。热感觉增强和热舒适性降低均与脑血流量增加显著相关。在高温环境(30゜C)下，儿童腿部浸泡热水浴(42゜C)时，直肠温度升高幅度小于年轻人。有人建议儿童在炎热的环境中主要通过干热流失来调节体温。穿T恤和短裤的日本和韩国女性对热(35゜C)和冷(5゜C)环境的热反应不同，但日韩两国女性对每种热应激的反应方式都受到穿和服还是穿韩服的影响。根据不同人群的体型或体型估算了体表面积与体重的比值，并计算了该比值与居住地平均气温之间的回归方程。日本男性和女性被发现完全包含在这种关系中。
