Outline of Final Research Achievements

This study evaluates the effect of the clothing fit (CF) on physiological and psychological responses. Experiments were conducted with five young male subjects to test the effect of CF of T-shirt of which four sizes were applied for individual subject: loose size(L), regular (R), fit (F) and compression (C). The tight T-shirts gave lower body surface temperature than that of regular. As a result of the verification of the accuracy of the commercially available WBGT meter, the size of the black globe influenced the accuracy. In order to verify the effect of the shape of thermometer on temperature, the thermometer of the shapes of globe, head and human body of polylactic acid (PLA) resin were manufactured with a three dimensional printer. PLA globe temperature is lower than copper globe temperature in outdoor condition due to the thermal resistance of the PLA resin. In case of non-uniform shape like head / human body, the temperature varies depending on the direction to the sun.
