Abstract

실험을 통한 한국형 체감온도지수를 개발하기 위하여 실험을 수행할 경우 필요한 피험자의 선발과정, 실험의 정확도, 피험자의 안전 및 실험에서 발생하게 될 여러 가지 상황을 대비하기 위해서 예비실험을 실시하였다. 예비실험에서는 저온에 의한 인체의 영향을 최소화하기 위해 영상 <TEX>$5^{\circ}C$</TEX>에서 풍속을 무풍에서 강풍으로 변화시키면서 실험조건과 인체의 안전에 대해 살펴보았다. 그 결과, 안면부 부위별 피부온도변화의 경우 얼굴의 오른쪽 부위이 기온과 풍속변화에 가장 민감하여 안정적인 변화경향을 나타내었으며 모든 피험자가 얼굴의 오른쪽 부위에서 가장 낮은 온도를 보였다. 성별에 따른 차이에서는 여성이 남성보다 더 민감하게 반응하였으며, 약한 풍속에서 피부온도가 크게 변화함을 알 수 있었으며, 기준풍속에 따른 영향은 체감온도지수 개발시 고려하지 않는 것이 바람직함을 알 수 있었다. This paper aims to develop a Korea wind chill temperature index using an experimental method. For this, the researchers carried out a preliminary experiment in order to of for provisions necessary for the selection and safety of test participants, accuracy of experiment, and readiness for various situations that may occur during experiment. The researchers also investigated test subjects' safety and experiment conditions in which wind speed changes from calm condition into strong wind speed condition under the constant air temperature of <TEX>$5^{\circ}C$</TEX>. The results of this study are as follows. With regard to the variation of facial skin temperature such as forehead, cheek, nose, and chin, the skin temperature of cheek closely appears to depend on the change of air temperature and wind speed, exhibit a stable variation trend of skin temperature, and indicate the lowest temperature than any other facial parts. The skin temperature of women tends to be more sensitive than that of man and the skin temperature of human tends to decrease at weak wind speed under constant air temperature. It was also found that it is not necessary to take the influence of standard wind speed into consideration when a wind chill index is developed.
