  • The purpose of this study was to compare the effect of clothing materials and the opening of the garment on the microclimate of the skin simulating system during the coupled heat and moisture transfer. To determine the effect of size and location of openness of the garment, openness was simulated by removing parts of the spacer ring of the modelling system. To evaluate the changes of humidity and temperature of air layer in the system, buffering indice, Kd and Pr, and efficiency of openness were determined. When the openness was imparted to the system, the transport rate of heat and moisture increased abruptly; at the total openness of 26.4%, which simulated the openness of neck, armhole and waist, Kd increased at least more than three times of the closed system. As the openness increased, the effect of clothing materials decreased gradually to lose its effect at the 60% openness and approached the value of nude. Temperature regulating index showed, however, higher value than nude which was apparently due to the still air layer.

  • The actual clothing conditions of male collegian were surveyed to analyse clothing contents and the rate of wearing underwear. Then, clothing microclimate, physiological responses, and subjective sensations were investigated through wearing trials on human body in climatic chamber based on the results from the survey. The results were follows: 1. Male collegian wore T-shirts, jeans, and socks in summer, and total clothing weight per body surface area was $561g/m^2$. The number of clothes for upper body were 1 layer, but the number of clothes for lower body were 2 layers. Subjective sensations have no significant difference with wearing underwear. 2. Most physiological responses including temperature inside clothing, mean skin temperature, skin temperature of chest, abdomen, thigh, and lower leg, and sweat rate, were higher in with-underwear than in without-underwear. But pulse rates were not significantly different between with-and without-underwear.

  • The rates of subcutaneos fat on the system of clothing weights including clothing microclimate subjective sensations were measured to get basic data to develop guideline for healthy clothing life. for this study skinfold thickness the rate of subcutaneos fot clothing microclimate subjective sensations and clothing weights were measured from 85 male and 105 female colligians. The results were as follows: 1. The rate of subcutaneos fat showed negative correlation with the temperature inside clothing in chest but not with the temperatures in back and thigh. The correlation was not significant between the rate of subcutaneos fat and humidity inside clothing 2. The correlation between the rate of subcutaneos fat and thermal sensations was positively significant at 5% level. However no correlation was found between the rate of subcutaneos fat and humid sensations. 3. There was significant correlation between the rate of subcutaneos fat and under clothing weights and total clothing weights.

  • Microclimate of open spaces on campus tends to be important because it is related with people's comfort and it can influences their behaviors in outdoor during summer. Climatic components for 4 points, concrete paving, lawn, landscaped pergola and nearby forest on university campus were measured and evaluated. The results show that the air temperatures on paving such as concrete and lawn under the direct solar radiation were higher than the temperatures of canopied spaces such as pergora and nearby forest by up to $7^{\circ}C$ during summer. Characteristics of temperatures on lawn were similar to those on concrete paving. After evaluation, concrete surface was worst among 4 points, while landscaped pergola was the most effective facility in terms of thermal comfort during summer.

  • There are many reasons of damage in Namhansanseong Yeojang. Lots of damage types are observed in each Yeojang. There are many types of damage factors but major damage factor is breakage by freezing and thawing. So Conduct non-destructive evaluation about damage factors in Namhansanseong Yeojang to analysis weathering factors in Yeojang by measuring directional microclimate. The study will pave the way for conservation management in Namhansanseong by suggesting the conservation calendar about weather condition and damage factors.

  • To do this study, we produced cooling vest newly. Rectal temperature was ascended approximately from 37.2$^{\circ}C$ to 38.05$^{\circ}C$ in lab, but wearing cooling vest, the temperature was descended 0.2 while wearing developed product compare with existing product. Mean skin temperature which was showed distribution from 32.8∼36.5$^{\circ}C$, it was descended 1.0∼1.1$^{\circ}C$, while wearing cooling vest and comparing with existing product, wearing developed product was lower 0.5$^{\circ}C$, While wearing developed product, it was found that they had lower tendency than exiting product. Specifically in case of temperature within clothing(chest) 0.2∼2.0$^{\circ}C$ in case of humidity within clothing 2∼8% RH. Facts from above we confirmed that clothing microclimate had been improved and space was happened between body and garment in order to control. In subjective sensation, existing product made negative response during experiment period from participants, but developed product was nearing to comfortable area.

  • The purpose of this study was to investigate the effects of silt ventilation system on physiological responses. We measured rectal temperature, local skin temperature, clothing microclimate, blood pressure, heart rate, energy metabolism, body weight loss and subjective sensation during 70 minute, 50 min exercise period and 20 min rest period. The five women subjects randomly wore sportswear without slit ventilation system(NS sportswear) and sportswear with slit ventilation system(S sportswear) under the environmental condition of $25^{\circ}C$, 50%RH. The results of this study are as follows; Rectal temperature, mean skin temperature, clothing microclimate, blood pressure, heart rate, energy metabolism and body weight loss were significantly lower level in 'S sportswear'. In 'S sportswear', subjects replied less hot, less uncomfortable and less wet. Slit ventilation system can be used for bellow effect which is meaningful device of convection during exercise. We could find out that 'S sportswear' has advantage in physiological function.
