인간이 각종 질병치료에 있어 열(온열)을 이용한 것은 고대의학의 시작과 그 역사가 함께 비롯된다. 이러한 온열요법은 방사선치료나 일부 항암약제와 병행할 때 그 효과가 상승되며 그 단독 사용만으로도 암세포를 죽일 수 있음이 최근에 와서 밝혀지고 있고 또한 병태생리학적 기전이 규명되고 있다. 한편, 온열치료기계 및 온도측정장치의 개발로 말미암아 암환자 치료에 온열치료의 임상적 응용이 각광을 받고 있다. 가톨릭의대 강남성모병원 방사선치료실에서는 1985년 3월 이후 1년 9개월 동안에 표재성의 전이 또는 원발암환자 42예(남 23예, 여 19예 ; 평균연령 56세)에서 외부방사선치료 또는 항암약물치료와 병행하여 가정용 전자레인지를 개조하여 만든 2,450MHz 극초단파를 이용한 온열치료를 실시하였다. 이 중 6예에서는 방사선치료 종료 후 재발되었기에 온열치료 단독으로 실시하였다. 온열치료 후 임상적 반응은 총 42예 중 종괴의 완전관해 부분관해 소관해 및 무관해율이 각각 11예$(20\%),\;15예(36\%),\;11예(26\%)\;및\;5예(12\%)$였다. 조직학적 진단은 편평상피암 $17예(40.5\%)$, 선세포암 12예$(28.0\%)$ 및 기타암종이 6예$(14.5\%)$였다. 완전관해를 보인 11예의 조직학적 진단은 편평상피암 5예, 선세포암 5예, 녹색종이 1예 였으며, 부분관해를 보인 15예는 편평상피암 5예, 선세포암 5예, 불명암 3예 및 미분화세포암과 기타암종이 각각 1예씩이었다. 방사선치료선량과 온열치료 횟수와의 관계는 $40\~50Gy/5\~7$주의 방사선치료와 1회 30분씩 주 2회, 총 $5\~9$회의 온열치료를 실시하였던 군에서 가장 온열치료효과가 좋았던 것으로 분석되었다. 한편 온열치료의 부작용으로는 일시적 치료부위 발적이 모든 환자에서 관찰되었으며 수술 후 켈로이드에 재발되었던 유방암환자 1예에서 자연치유되는 2도 화상을 경험하였다.

This study was performed to define the effects of Far Infrared Ray Radiation Fabrics as summer garments during outdoor work by human trial. One healthy male subject was volunteered for this study. Experimental garments consisted of three kinds of trousers (Cotton, Cotton/linen blended, Far Infrared Ray Radiation Fabric/wool blended) and basic garments (panty, socks, shirts, and dress shirts). The measurements were rectal temp., skin temp., microclimate inside clothing, heart rate, subjective sensation etc. The results were as follows : 1. Rectal temperature showed the lowest in Far Infrared Ray Radiation Fabrics among 3 garments. 2. Skin temperature (forehead, chest abdomen temp.) and mean skin temperature were lower in Far Infrared Ray Radiation Fabrics than in others, especially during early stage of work. 3. Heart rate showed lower value in Far Infrared Ray Radiation Fabrics than in others but there was no significance among the garments. 4. Humidity inside clothing and total weight loss showed the highest value in Far Infrared Ray Radiation Fabrics.

This study aimed to measure the amount of sweating on 12 parts of the upper body using absorption fabric and analyze subjective sensations. The study was conducted with 9 male subjects in climate chamber controled at $30{\pm}0.5^{\circ}C$, and $55{\pm}5%$ RH. The result was that sweating amount of the upper back part was significantly more than upper front part. We assumed that forced convection flow cased by exercise decreased the sweating rate in the front. The skin temperature of upper front body rapidly decreased as soon as exercise starts and gradually increased with cessation of exercise. On the other hand, the skin temperature of palm increased with exercise and showed continuous increasing even exercise stopping all the experimental period. This is caused by thermoregulatory responses through vasodilatation on the peripheral area. Subjective sensations, such as thermal sensation, wet sensation, and thermal comfort showed the highest score at the time of exercise stop. This means the subjects felt more hot, wet, and uncomfortable after exercise stopped. Bur after wiping of sweat, subjective sensation scores were recovered rapidly. The present study has provided more detailed information on the upper body sweat distribution than previously available, which can be used in clothing design, thermo-physiological modeling, and thermal manikin design. We also think that results of the present study will play an important role in making the sweat distribution map.

This study was done to investigate thermal reponses and to obtain the basic information of thermal comfort by sex and posture under the Ondol heating system. Six healthy males and females were exposed to Ondol(Room Temp.: 25$\pm$1$^{\circ}C$, 50$\pm$10%R.H, Floor Temp.:30$\pm$1$^{\circ}C$) on the of posture such as sitting, lying aside and supine on the floor for 30 minutes after 30 minutes' control phase. During the experiment, rectal temperature, skin temperature of 10 areas, local sweating rate, clothing microclimate, subjective sensation were measured. Rectal temperature gradually decreased and mean skin temperature grad-ually increased both male and female in any posture. There was not significant difference between male and female in rectal temperature and mean skin temperature. There were significant difference among the postures in rectal temperature(p<0.001) and mean skin temperature(p<0.001). In lying aside and supine on the floor, appearances of change and changes in rectal temperature and mean skin temperature were large, changes of weight were small. In sitting on the floor, appearances of change and changes in rectal temperature and mean skin temperature were small, changes of weight were large. The trunk skin tem-perature was higher in female than in male, but the extremity skin temperature was higher in male than in female. In sitting on the floor, foot skin temperature(p<0.001) was higher than any other local skin temperature. In supine on the floor, back skin temperature(p<0.001) was higher than any other local skin temperature.

The purpose of this study was to compare the thermophysiological responses and subjective sensations of clothing materials with different water transfer property investigated in exercising and resting subjects at an ambient temperature of $20^{\circ}C$ and a relative humidity of 40%. Two kinds of clothing ensemble were tested: 100% cotton with highly water-absorbent but slowly dry properties(C) and 100% polyester with quickly water-absorbent and dry properties by four capillary channels(QADP). Seven apparently healthy male participants each undertook two series of experiments comprised 10-min of rest, 20-min of exercise with 70% of $VO_{2max}$ on a treadmill and 20-min of recovery. Mean skin temperature was significantly lower in QADP than in C during exercise and recovery. Clothing microclimate temperature was significantly lower in QADP during exercise and clothing surface temperature was also lower in QADP especially during recovery. Also, clothing surface humidity was significantly higher in QADP after the later half of exercise. The concentration of blood lactic acid tended to decrease to a lower level at recovery 3 minutes when wearing QADP rather than C clothing ensemble. Metabolic energy was marginally significantly less during the second half of exercise in QADP. Body mass loss tended to be greater in C than in QADP. The participants had better scores in thermal sensation, comfortable sensation and wetness in QADP during exercise and recovery. These results show that functional materials with quickly water-absorbent and dry properties can alleviate heat strain and induce more comfortable clothing microclimates and subjective sensations in the exercise-induced hyperthermia.

In this research, the psychological and physiological reactions of the driver were measured during winter to evaluate thermal comfort. The experiment was conducted using 3 different cases which are hot air heating, warm-wire seat heating and hot air & warm-wire seat heater operating simultaneously. With regard to psychological reaction, the warm-wire heating mode was the most preferred. The reason is that it is dry in other cases. With regard to EEG response, thermal comfort increased by 37% in warm air mode heating. In addition, when the warm-wire heating mode and the hot air & warm-wire heating mode were simultaneously operated, the thermal comfort continuously increased by between 17% and 20% for 20 minutes after boarding. Under the change of the autonomic nervous system, the thermal stress level increased by 23% after 15 minutes on board in the hot air heating mode and decreased continuously by 13% during the warm-wire seat heating mode. We recommended the hot air heating mode is only used for a short time to raise the inside temperature during the early boarding period and that warm-wire seat heating mode be actively utilized.
