A Study on Experiments the Environmental Conditions and the Adaptation of the Human Body in the Vinyl House / 예방의학회지

ABSTRACT

The purpose of this study is to experiments the environmental conditions and the adaption of the human body in the vinyl house. The study was done in spring and winter and experimental clothes were used working clothes in the vinyl house. The results are as follows. 1. Environmental conditions; In the spring season, the indoor air temperature was 27.4+/-3.7 degrees C and the outdoor air temperature was 14.4+/-2.7 degrees C. In the winter season, the indoor air temperature was 18.3+/-4.8 degrees C and the outdoor air temperature was 7.6+/-2.5 degrees C on the average. 2. Skin Temperature; In the spring season, the mean skin temperatures indoor and outdoor were 33.81+/-0.7 degrees C and 31.57+/-0.8 degrees C respectively, a difference of 2.24 degrees C. In the winter season, they were 31.95+/-1.93 degrees C and 29.86+/-0.55 degrees C respectively, a difference of 2.09 degrees C. 3. Clothing climate; In the spring season, the temperature and humidity in the inner layer of clothing were 34.77+/-0.80 degrees C and 70.75+/-1.65% and indoor, 31.9+/-0.52 degrees C and 51.9+/-3.70% outdoor respectively. In the winter season, those were 32.52+/-1.04 degrees C and 64.65+/-3.68% indoor, 30.27+/-0.96 degrees C and 45.07+/-2.68% outdoor respectively. 4. Physiological Factors; Body temperature increased slightly and the pulse rate also rises, but blood pressure decreased a little with the rise of environmental temperature both in the spring and winter seasons. 5. Psychological Factors; Thermal sensation in the spring season was expressed as "slightly larm" or "warm" indoor and as "neutral" in the open air, while in the winter it was expressed as "neutral" or "slightly warm" outdoor the house and as "cold" in the open air. Comfort sensation was characterized as "uncomfortable" or "slightly uncomfortable" indoor both in the spring and winter seasons, but in the open air it was characterized as "comfortable" in the spring and as "slightly uncomfortable" in the winter.
