This paper is to clarify a thermal physiological index that can account for the effects of local thermal environment. For this purpose two young female subjects exposing themselves to the above while sitting on a chair, sitting on the floor and lying on the floor were measured. These three representative postures accompanied the different contact surface areas, thereby the heat conduction rate between the floor and subject was quantitatively measured for each posture. It made the present study deal with the effect of heat conduction concerning the modified mean skin temperature and finally propose new weighting coefficients for the mean skin temperature calculation based on the Hardy & DuBois' formulas. In order to verify the proposed model, the experiment was carried out using a floor heating system. The comparison between the experimental result and prediction revealed that the proposed model should be about 10% more accurate than the conventional one in the case of lying on the floor which the heat conduction effect becomes important.

The purpose of this study was to obtain the basal information for standard amount of clothing weight indoor climate and working condition with investigating seasonal changes of skin temperature and factors influencing on that in Koreans. Forty eight subjects in 5 age groups(6-11, 12-19, 20-44, 45-64, 65-76 years old) with both sexs were measured skin temperature indoor climate clothing microclimate clothing weight and skinfold thickness in neutral condition in each month throughout the year. The results obtained are summarized as follows : 1. Indoor climate koreans felt comfortable ranged 18.1-28.7$^{\circ}C$ and 51-74%RH. 2. Temperature inside the clothing ranged 30.8-32.3$^{\circ}C$ in males and 31.0-32.5$^{\circ}C$in females. There was a significant difference in temperature inside the clothing among age groups : That of 6019 age group was slightly higher than that at 45-76 age group. 3. Total clothing weight changed with season and increased in order of summer autumn spring and winter Total clothing weight of 65-76 age group was significantly greater on January and February. Breast skinfold thickness showed the smallest value in summer and the largest value in winter year. In addition to breast and abdomen skinfold thickness were larger in 45-67 age group while thigh skinfold thickness was larger in 6-19 age group. Skinfold thickness in females showed the smallest value in spring summer and the largest value in autumn and winter. In addition to triceps and suprailliac skinfold thickness were larger in 45-64 age group while thigh skinfold thickness was larger in 12-19 age goup. 5. Temperature of the lower limbs(hand, thigh. leg, and foot) showed significant correlation with the indoor temperature humidity inside clothing and total clothing weight. Temperature of the torso(breast and abdomen) showed significant correlation with the temperature inside clothing in all subjects. Abdomen skinfold thickness of all age group in male showed significant correlation with the abdomen skin temperature. triceps suprailliac and thigh skinfold thickness of 6-11 age group in female showed significant correation the upperarm abdomen and thigh skin temperature. Consequently clothing mdicroclimate total clothing weight and skinfold thickness showed significant difference in season sex and ages and had a slight effect on skin temperature.

This study was conducted to investigate the effects of skin surface temperature on transdermal absorption of active substances and changes in skin condition. A transdermal absorption test was conducted using an emulsion containing 10% heat-resistant niacinamide, and the same emulsion was used in a clinical trial to test the thermal effects. As a result, absorption was found to be 2 times greater at 10 minutes and 3 times greater at 15 minutes after application at $42^{\circ}C$ than that of compared to normal skin temperature. During the clinical evaluation on skin, no clinical subjects showed any specific adverse reactions, while moisture and oiliness showed statistically significant effects at higher temperatures. Based on these results, it was confirmed that thermal warmer improves the absorption of active substances and had a positive effect on skin condition. It is deemed that this study will provide a preliminary data to support the development of various beauty devices using heat.

In order to evaluate physiological responses and comfort sensation of the developed thermoregulating textile material, polyester knit fabric was treated with phase change material (PCM) microcapsules by printing. Ten male subjects wearing an experimental best with and without PCMs were seated for 20 minutes, then exercised for 20 minutes, and then seated for 30 minutes in the chamber which was controlled under the temperatures of 20$\pm$1$^{\circ}C$, 50$\pm$5%R.H. The subject's skin temperature, microclimate inside garment and comfort sensation of two experimental bests were compared one another. As a result, the rectal temperature, skin temperature and mean skin temperature were similar in the two groups, and the subjects were not able to perceive the differences in comfort of the two experimental bests. However, the effect of PCM microcapsule could be seen from microclimate temperature and humidity. The microclimate temperature of the PCM garment at chest was significantly higher during exercise. The microclimate humidity of the PCM garment at chest was significantly lower during exercise and rest.
