This study was conducted to investigate the effects of the thermally different states of human feet on temperature regulation in winter season. Five healthy female students of age 20 volunteered as subjects to participate in the study. Physiological responses such as rectal temperature and skin temperatures as well as subjective responses of thermal comfort and thermal sensation were observed. Preferred clothing and preferred temperature were also evaluated in terms of behavioral temperature regulation. The results obtained through the experiment were statistically analyzed using paired t test. Rectal temperature was decreased greater (p<.01) and mean skin temperature was maintained higher (p<.01) in feet wanning than in feet cooling. Results of preferred clothing were coincident with those of general thermal sensation. There was a higher tendency to prefer temperature in feet wanning than feet cooling in the morning. It was concluded that keeping feet skin temperature lower in the early morning and higher in the late evening would be effective in terms of regulating circadian rhythm of core temperature.

The actual clothing conditions were surveyed to diagnose clothing condition of Korean female in the view point of the adaptation to the thermal environment according to seasonal changes. Then, clothing microclimate, physiological responses, and subjective sensation were investigated through wearing trials on human body in climatic chamber based on the results from the survey. Factors to evaluate validity of clothing condition were clothing weight, clothing microclimate, physiological response of human body, and subjective sensation. The results were as follows: 1. Clothing weight per body surface area of the season was $856g/m^{2}$, $439g/m^{2}$ in summer, $630g/m^{2}$ in fall, and $1184g/m^{2}$ in winter. Cold - resistance of Korean female in office was superior to Japanese, inferior to residents of rural areas of Korea, and similar to male in office. However, in heat - resistance, female in office was inferior to residents of rural areas of Korea. 2. In spring, fall, winter, clothing microclimate temperature was a little higher than that in summer. Therefore, it was not a desirable wearing condition even though the clothing microclimate was comfortable zone. 3. Mean skin temperature of female in office was including within the range of Winslow's comfortable zone, but the range of comfortable zone in mean skin temperature of female was more narrow than Winslow's. Thus, it has problem for female to adaptation to thermal environment.

The purposes of this study were to find out an evaluation scale that could predict wear comfort and to investigate the effect of the skin-contacting fiber type on the subjective sensation and microclimate. Sensorial evaluation was basically followed by the Human Perception Analysis (HPA) interviewing 144 consumers. Sixteen female subjects were participated in the sleeve wear test with and without wearing vapor permeable water repellent outerwear. Experimental sleeves were constructed using the same double knit by turning inside out to control other material effects except the skin-contacting fiber type, hence each different side of double knit, cotton side and the cotton/polypropylene blend side, was next to skin in each trial of the experiment. As results, it was noted that the term representing a combined feeling of thermal and wetness sensation, and muggy appeared to be a powerful language to measure perceptual responses of human subject among five dimensions of evaluation. although the ordinary users did not use the term very often. As for the comfort properties of double knits, it seemed that subjects slightly more preferred polypropylene/cotton blend to cotton as the skin-contacting fiber type when they wore outerwear and their skin were covered with sweat, although the result was rot statistically significant and need to be confirmed under higher work load.

The purpose of this study is to investigate the effect of Ondol on the bedclimate, microclimate and physiological responses of occupants. Four healthy female subjects slept for seven hours in thermal environment of detached house and apartment respectively. Their bedclimate, microclimate, skin temperature, weight loss of body, weight of bedcloth and sleepwear, body movement and subjective sensation were measureed for this study. The results were as follows; The differences of bedclimate, microclimate, skin temperature were significant according to season and residence styles. The occupants of the detached house showed higher temperature and humidity inside quilt and clothes than those of the apartment did on apartment environment. The occupants of the detached house showed higher weight losses of body, heavier weights of quilt than those of the apartment did on apartment environment in the spring, autumn and winter, lower weight losses of mattress in the autumn and winter. The occupants of the detached house moved more than those of the apartment on apartment environment when sleeping. The occupants of the detached house felt higher thermal sensation and lower humidity sensation than those of the apartment did. The occupants of the detached house felt more comfortable than those of the apartment on detached house environment, while the occupants of the apartment felt more comfortable than those of the detached house on apartment environment. The thermal environments of the apartment and the detached house had an effect on the bedclimates, microclimates of occupants and therefore the physiological responses such as skin temperature, rectal temperature, weight loss of body, perspiration and subjective sensation are different during sleeping according to their residential styles on the same environment.

In recently, Is inhabiting more than 70％ indoors during a day in case of company employee and ordinary people which is looking at usual business. Therefore Thermal comfort of human body about indoor temperature and air flow acting very heftily. When intestine temperature is fallen for external low temperature and air flow in winter in case enter into heated room feel comfort by effect of temperature and feel comfort or discomfort by room heating condition gradually. Therefore it is important that grasp thermal comfort about temperature and air flow in heating to keep continuous comfort in indoor dwelling. Temperature and thermal comfort factor of emotion ＆ sensitivity image exert fair effect since heating middle although thermal comfort change greatly effect on sensation about temperature at actuality heating early. Need much study yet in vantage point of emotion ＆ sensitivity although much study were held about thermal and comfort sensibility and when heat in existing research until now. Therefore this study is targeting that evaluate thermal comfort through introduction of estimation method by emotion ＆ sensibility image real and synthetic sensibility about thermal environment that is becoming winter heating.

Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, silver generation considered all the clothing comfort sensations important when wearing clothes, such as tactile sensation, clothing pressure sensation, thermal/wet sensation, and motion sensation in human physiological aspect. Also, stretchy fabrics were ranked first in awareness, the number of wearing times, and satisfaction of comfort functional fabrics. More than 30% of silver generation have fifteen items out of 36 functional clothes. Second, in analysis of awareness by gender on functional clothing products, women were more aware of health/safety-oriented fabrics than men were. Otherwise, men had more knowledge about the water-related properties of functional fabrics than women have, such as water/moisture absorptive and water-repellent/vapor permeable fabrics. While women have more indoor casual wear, men had more active sportswear. Also, women expressed a strong preference to the stretchy function of fabrics.

This study analyzed a subject's body reaction and subjective sensation when wearing a gait-assistive rehabilitation robot. The research method measured skin and clothing surface temperatures for 'seating-standing' and 'walking in place' exercises after wearing a gait-assistive rehabilitation robot. In addition, subjective sensation and satisfaction were evaluated on a 7-point Likert scale. The study results showed that the average skin temperature during exercise while wearing the gait-assistive rehabilitation robot was within a comfortable range. However, during the 'seating-standing' exercise, the skin temperature was slightly lowered. Additionally, the clothing surface temperature tended to be lower than the pre-exercise temperature after all exercises. The subjective sensation evaluation results showed that the wear comfort of the waist part was low during mobility/activity. In addition, an overall improvement in the wear comfort of the robot is necessary. The short-time movement of wearing and walking in the gait-assistive rehabilitation robot did not interfere with the thermal comfort of the body. However, the robot needs to be ergonomically improved in consideration of the long wearing time along with improved material that to satisfy overall wearing comfort.

본 연구의 목적은 직물 소리의 주관적 감각을 결정하는 객관적 성질 중 가장 밀접한 관계를 지닌 것으로 보고되고 있는 물리적 음압 외에 직물 소리의 미세한 감각 차이를 설명할 수 있는 2차적 물성들을 규명하는 데에 있다. 3dB 이내의 유사 음압을 보이는 전통 견직물 다섯 종을 선택하여, 음향학적 물성치로 음색 요인인 ${\Delta}L$과 ${\Delta}f$, 심리음향학적 요인인 sharpness[z], roughness[z], fluctuation strength를 측정하고, 직물의 역학적 성질로서 Kawabata Evaluation System (KES)의 17개 물성을 측정하였다. 주관적 감각은 자유식강도측정법에 의하여 부드러움과 시끄러움을 포함한 7개 감각을 평가하였다. 연구 결과, 유사음압의 전통 견직물의 소리에 대한 주관적 감각 중 객관적 물성과 유의한 상관관계를 보이는 감각은 맑음과 거침, 높음이었다. 견직물 소리 간에 차이를 보인 맑음과 거침은 음색 요인인 ${\Delta}L$에 의해 영향을 받아서, ${\Delta}L$ 값이 큰 직물일수록 소리가 더 맑고 덜 거칠게 느껴지는 것으로 나타났다. 또한 주관적인 높음은 roughness[z]와 ${\Delta}f$와 유의적 상관관계를 나타내어, roughness[z] 값이 커질수록 또는 ${\Delta}f$값이 작아질수록 소리가 더 높게 느껴지는 경향을 보였다. 따라서 유사음압의 전통 견직물의 소리 감각은 음압 외에 roughness[z]와 음색 요인들에 의하여 결정되며, 이를 전통 견직물의 소리 설계에 활용할 수 있을 것으로 기대된다.
