본 연구는 도시 소공간의 열환경을 개선하기 위한 방안을 모색하고자 공간 구조별 열특성을 평가하여 분석하였다. 도심 내 위치한 고려대학교 캠퍼스를 연구 대상지로 선정하였으며, 대상지 내에 공간 유형을 대표하는 각각의 장소에서 열환경을 조사하였다. 기상장비를 활용한 미기상 및 바이오 기상 측정, 어안렌즈 촬영사진(Fish-eye lens photography)를 활용한 공간구조 및 특성 분석, 그리고 온도나 습도와 같은 기상정보 및 이미지 정보를 활용한 열쾌적성 모델링의 순서로 공간의 열환경 및 인체 열쾌적성을 분석하였다. 열환경 평가 결과, 인체 열쾌적성의 정도는 캠퍼스 공간의 유형에 따라 차이가 나타났다. 건물이나 수목 등에 의해 위요된 폐쇄형 공간 유형에서 개방형 공간 유형에서 분석된 평균 복사온도, PMV, PET 지수보다 더 양호한 것을 알 수 있었다. 이러한 결과는 수목과 건물에 의한 태양복사열의 차단 및 그림자의 영향을 받기 때문이라고 할 수 있다. 그러므로 공간을 계획할 때 개방성이나 통풍성을 높이기 위한 수목의 배치를 고려하고 복사열을 차단할 수 있는 바닥포장이나 건물 외장재 종류를 선택할 필요가 있다. 본 연구는 도시 공간의 이용자가 실제적으로 느끼는 열쾌적성의 정도를 정량화하고 이를 평가함으로써 이용자를 고려한 공간계획 방안을 제안하였다.인체 열쾌적성을 평가하는 정량적 평가 방법 및 그에 따른 연구결과는 향후 도시 공간의 쾌적한 환경을 조성하는데 기여할 수 있을 것으로 판단된다.

As the recent advancement of automobile industry, there has been a great interest in the thermal comfort of the passengers inside the cabin of an automobile. Thermal comfort is affected by temperature, velocities, and mean radiation temperature of air, thermal resistance of clothes and physical active level of human. The present study performed computational analysis to select the location of air-conditioning vent that improves thermal comfort inside the cabin. In order to do this, we considered various air vent positions, and thermal flow analysis of each case is performed using CFD for the cabin with four passengers. The thermal comfort is evaluated using the computational results and the optimum location of air vent is suggested.

For this study, we developed clothing in which textile materials that were excellent weather control function for the cold environment and we performed the human subject test with developed clothing to determine the thermal comfort. We used 2 clothing samples developed (A and B, hollow yarn+moisture absorption/quick drying yarn, 3 layers, high stretchable, heat reflection film and lamination treated) and a control sample (Ctrl.) for the human subject test and 8 adult males were used as a human subjects and environmental conditions of chamber were $0{\pm}1^{\circ}C$. $50{\pm}5%RH$, 0.3m/sec. The results were as follows: The average skin temperature and hand, thigh temperature of B were higher than B and Ctrl. (p<.05). The micro-climates of B were near to thermal comfort range which is $32{\pm}1^{\circ}C$ and $50{\pm}10%\;RH$. The chest temperature of B was significantly higher than others (p<.05). The relative humidity of B was lower than others and kept stable rather than others. The thermal sensation of B was near the "neutral" and was significantly different from Ctrl. (p<.01) and the weight loss of B was lower than Ctrl. (p<.05). The counting task and hand temperature was positively related and the counting task value of B and A is bigger than Ctrl. and that of A was bigger than Ctrl. (p<.05).

자동차 시트의 만족도 평가방법은 디자인을 평가하는 방법에서부터 출발하여 완충시스템과 재료를 평가하는 기계적 방법을 지나 인간의 주관적인 감정을 평가하는 현재까지 이르렀다. 국외에서는 지난 10여 년간 자동차 시트의 만족도 평가를 위한 수많은 연구가 진행 되었고, 2006년에 설문지에 기반을 둔 통계적으로 신뢰할 만한 평가방법이 만들어져 외국에서 널리 사용되고 있다(Baba 등, 2008). 그러나 우리나라에서는 아직까지 이 방법이 활용되지 못하고 있는 실정이다. 따라서 본 연구에서는 Smith 등 (2006)의 연구방법을 중심으로 기존 연구를 분석하여 한국인에 적합한 평가 설문지를 새로 개발하였다. 6명의 자동차회사 및 시트 전문회사의 전문가들의 의견을 반영하여 기존연구에서 감성평가 항목이 중복되어 있거나 우리나라에는 적합하지 않는 항목은 제외시키고 유사한 항목들은 통합 하여 36개의 평가항목을 새로 개발하였다. 이들 항목은 유사성을 고려하여 대분류, 중분류, 소분류로 분류하였다. 36개 평가항목은 중요도가 다르기 때문에 계층화분석법(AHP)을 사용하여 평가 항목의 중요도를 결정하였다. 본 연구에서 개발된 자동차 시트 만족도 설문지는 우리나라에서 생산되는 자동차 시트의 주관적 감성 평가에 널리 활용될 수 있을 것이다.

Calculating and predicting the thermal comfort in outdoor environment are difficult than in indoor environment because composition parameters are variable, interrelations among parameters are very complex and human activities in outdoor are diverse. Moreover, the thermal expectancy of subject in outdoor environment is different from that of indoor environment. The aims of this study are to examine the difference between indoor and outdoor thermal comfort range. With this in mind, field measurement for estimating outdoor thermal environment and a questionnaire survey with simultaneous measurement around the subject were conducted.

In this paper, the driver seat comfort of eight automobiles was studied. The joint angles and anthropometric data of eleven subjects sitting on the seating buck were investigated using the instrument devices such as scale, goniometer, vernier calipers, protractor, Martin set. The joint angles of the most comfort posture were found by experiment and compared with previous studies. The anthropometric data of Korean(1992 year surveys) and American(1970∼1974 year) were applied to evaluate the driver seat layout of Korean automobile. The joint angles of the most comfort posture for eleven subjects were obtained with experimental results. The joint angles were agreed with reference angles. The driver seat layout was not suited to seat length and acceleratorseatpan forward distance in 5 percentiles female, pedal separation and seatpan-roof height in 95 percentiles male. Korean automobiles were not suited to seatpan length and steering wheelseatpan clearance, floor-roof height for American 95 percentiles male. The driver anthropometric dimensions were more suitable to middle size than small size automobiles.

Comfort concept of heating and cooling between body and environment is modified by the clothing. So were can say the clothing is one of the environment. To maintain“pleasantness”, clothing must have the elements of comfort and function. This study carried out for the 1st step to describe the relation between clothing and the human body I aspect to the emvironmental elements of temperature and working part of the body. Observations of skin temperature were taken on young adults female subjects in training wear and the skin temperature was measured onto 9 points of the body while taking part in two physical exercise, with Rawing machine and Bicycle ergometer. The results obtained are as follows; 1. The skin temperature after physical exercise is lower than that after repose. 2. After physical exercise of the lower part of the body, the skin temperature is less than that after physical exercise of the upper part of the body. 3. After physical exercise of the upper part of the body, skin temperature of the lower part of the body rises a little, and vice versa.

Vibrations on the floor in a car are transmitted to the foot, hip, and back from the seat. Human body recognizes these vibrations, but the sensitivity for each vibration is different. To evaluate these vibrations, RMS(root mean square) of accelerations, VDV(vibration does value) are commonly used. The ride comfort evaluation is usually carried out by experiments of real cars which are expensive. The purpose of this paper is to briefly review the status of several ride vibration standards and criteria having relevance to construction machinery vehicles and to suggest recommendations for the effective use of such criteria in vehicle / component development.

This study evaluates wear comforts of water-vapor-permeable (WVP) garments through a measurement of various parameters such as skin and rectal temperatures, microclimate between skin and clothing, sweat rate, and subjective sensations (thermal, wet and comfort sensations) to correlate the physiological responses of the human body with its comfort feeling. Wear comfort during a specific exercise on a treadmill in a climatic chamber (temperature T = $20{\pm}0.5^{\circ}C$ and relative humidity H = $50{\pm}10%$) were studied using eight men wearing seven sportswear outfits (a long sleeve shirts and a long pants) made with seven different WVP fabrics. A comfort sensation was found to be highly correlated with skin T (p<.001), microclimate (T and H) between skin and clothing (p<.001) and sweat rate (p<.05). A regression model correlating comfort sensations and physiological responses obtained from wearer trials could be established: Y = 14.167 - 0.362 ${\times}$ X1 + 0.424 ${\times}$ X2 - 0.238 ${\times}$ X3 - 0.561 ${\times}$ X4 + 0.253 ${\times}$ X5 + 0.214 ${\times}$ X6 - 0.393 ${\times}$ X7 + 0.023 ${\times}$ X8 - 0.043 ${\times}$ X9. (Y = comfort sensation, X1 = forehead skin T, X2 = forearm skin T, X3 = hand skin T, X4 = thigh skin T, X5 = T of chest microclimate, X6 = T of thigh microclimate, X7 = chest sweat rate, X8 = H of back microclimate, X9 = H of thigh microclimate. The regression model obtained in this work can be used by manufacturers to objectively estimate the comfort sensation of sportswear before it is introduced to the consumer market. This study provides salient information to sportswear manufacturers and sportswear consumers.
