  • In order to find out whether solar air conditioning system could be applied to building or not, the performance and evaluation on thermal environment of the system suggested was done during summer. A solar model house was constructed to find out the performance and thermal environment evaluation when it actually operated outside. As a result, regeneration rate increased rapidly when LiCl solution temperature was over $50^{\circ}C$ and the regeneration rate was $13\sim15kg$ during 9 hours operation. Furthermore the dehumidification rate was 12kg at maximum during 10 hours operating of a dehumidifier and indoor temperature and relative humidity was $28.4^{\circ}C$ and 39.1% in average respectively. On evaluation of thermal environment during summer, PMV value was slightly high, but thermal sensation vote was 71% within the comfort zone.

  • The purpose of this study was to evaluate the effect of various knitted fabrics of sports socks on their properties of hygiene and stability. Seventeen men\`s sports socks to represent five groups with different fiber content, knit structure, yarn fineness, and finishing were used. Properties of hygiene and stability of socks were determined. The results were as follows ; 1. Evaluation of Water, vapor and heat transport properties in socks with varing fiber content showed that cotton 100% socks had the highest drop absorbency, wickability, water absorbency and water retention. Polypropylene 100% socks had an excellent wickability and moisture permeability. Acrylic blend socks had the highest thermal resistance. 2. The greatest knit stretch and knit growth of socks having lower power were found to be with cotton 100% socks had the lowest stretch. Acrylic blend socks had a excellent stretch but low fabric growth, which could give a good fir sensation during wear. 3. The commerical antimicrobial finished socks showed excellent durability after repeated cycles of laundering. 4. Length and width shrinkages were found in all laundered samples during initial cycles due to rearrangement by mechanical relaxation. Shrinkages showed no further changes and reached equilibriums after 5 cycles. Cotton 100% or cotton blend socks showed lower dimensional stability than other socks during fabric care.

  • Erysipelas is a inflammatory disease that characterized by erythrism, heat sensation, swelling, pain and tenderness. In initial invasion chilling sense and hyperthermia occur suddenly and local skin turn into red like coating with paints. it spreads promptly and the boundary is manifest. the position of invasion is not settled and it recur over again. Compared with western medicine it is similar to the inflammation caused by group A p-hemolytic streptococcus. If a proper care for erysipelas is not done in the time of expiration. Inflammation diffuse on circumferential skin and Iymphnode due to the diffusion of pathogene. In serious case. it can lead to death by ichoremia. We have four healing cases using 'younkyopaedok-san' that obtain good results and report it.

  • 최근에 관광기후지수가 생리등가온도(PET)와 범용열기후지수(UTCI)와 같은 완전한 인간 에너지 균형 모델들을 포함함으로써 발전되어 오고 있다. 이 연구는 해변에서의 조경계획 및 설계를 위해, 2015년 봄과 여름에 대한민국 제주특별자치도 월정리해변에서 인간 열환경지수 및 열쾌적성을 조사하였다. 미기후 측정과 국제표준화기구 10551을 바탕으로 만들어진 설문조사를 동시에 실시하였으며, 성인 869명이 참가하였다. 그 결과, 생리적인 요소만 고려된 '열환경 지각'과 '열환경 선호도'가 선형 회귀 분석에서 생리등가온도와 92.8과 87.6%의 높은 결정계수를 나타내었다. 그러나, 생리적 요소와 심리적 요소 둘 다 고려된 '열환경 평가', '열환경 수용도'와 '열환경 부담도'에서는 60.0, 21.1, 46.4%로 낮은 결정계수를 보였다. 그렇지만, 생리등가온도와의 상관성 분석에서는 모두 0.01 레벨에서 유의성이 있는 것으로 나타났다. 인간 열환경 지수를 나타내는 '열환경 지각'에서 덥지도 춥지도 않는 '중간'의 생리등가온도의 범위는 $25{\sim}27^{\circ}C$로 나타났으나, 미국의 냉온난방협회 표준 55에서 추천한 20% 이하의 불만족성 범위는 없었다. 다만, '열환경 평가'와 '열환경 부담도'에서 $21{\sim}32^{\circ}C$$17{\sim}37^{\circ}C$의 생리등가온도 범위들이 그 추천범위에 속하는 것으로 나타났다. 그러므로, $21{\sim}32^{\circ}C$의 생리등가온도를 해변지역의 조경계획 및 디자인뿐만 아니라 관광 및 레크리에이션 계획을 위한 인간 열쾌적성 범위로 적용될 수 있을 것이다. 해변에서의 열 스트레스 레벨들은 한국의 내륙들보다 $2{\sim}5^{\circ}C$ 높게 나타났으며, 대만과 나이지리아와 같은 열대지역과 유사한 높은 결과들을 보였고, 서 중유럽과 이스라엘의 텔아비브보다 높은 것으로 나타났다.

We looked through all the papers, excluded unintended papers, and finally chose some papers that are suitable for inclusion. Then, We extracted all the patterns of Acne vulgaris and chose frequently suggested patterns. Finally we extracted symptoms from selected patterns and arranged them in order of frequency. Results and Conclusions : 1. We found 215 papers and chose 17 papers (Korean : 6, Chinese : 11). 2. We extracted total 67 demonstrations and chose Patterns of Wind-Heat, Damp-Heat, Phlegm and Static blood, Disharmony of the Thoroughfare and Controlling vessels. 3. In Acne vulgaris, the pattern of Wind-Heat tends to have a red papule, sometimes pustule, pain with itching, burning sensation, tidal reddening of the cheeks, white head or black head. The pattern of Damp-Heat tends to have a pustule, node, redness and swelling, pain and greasy skin. The pattern of Phlegm and Static blood has a tendency to be a nodule or cystoma that is hard, dark, painful, long lasting and hard to recover and easy to recur with a scar, pimple, pigmentation. The pattern of Disharmony of the Thoroughfare and Controlling vessels tends to be exacerbated before menstruation, have a small papule that is not easily treated under the chin or around the mouth.

  • Persimmon juice dye-printed fabrics with printing were used for a Galot one-piece dress. The Galot dress was assessed in comparison to a white undyed one-piece dress of the same design through a wearing test conducted in a climatic chamber with an air temperature of $30{\pm}1^{\circ}C$, $50{\pm}5%$ R.H, and 0.2m/sec air movement on 4 healthy female subjects in their 20s. The subjects went through a 30-min stable period, a 30-min exercise of walking on a $5^{\circ}$ slope treadmill at 70m/min period, and a 20-min recovery period. In addition, a physiological reaction and subjective sensation were estimated. The results showed that significant differences were mostly observed from a sweating period that occurred during the latter half of the exercise. More specific results are as follows. First, skin temperature on the chest and mean skin temperature were significantly higher (p<.01) in rayon dyed sample dresses. Second, micro-humidity on the back showed a significant difference (p<.01). Both cotton and rayon persimmon juice dyed sample dresses produced lower microhumidity than their counterparts and as for cotton the difference occurred over the entire experimental period; however, it occurred after the middle of the exercise period for rayon. Third, the sweating rate on the back decreased in both cotton and rayon with persimmon juice dye but no significant difference was observed. Fourth, subjective three sensations revealed significant differences between cotton and rayon (p<.01), indicating that the subjects felt more cool, dryer and more comfortable in a cotton Galot. As described above, the analysis of physiological responses and the subjective sensation of undyed and dyed clothing shows the effect of persimmon juice dyeing. Persimmon juice dyeing also seemly increased air permeability, moisture regain and permeability facilitating body heat ventilation, as micro-humidity and sweat rate were lowered. However, this was not shown consistently in subjective responses on comfort especially when wearing rayon dresses.

  • Dust-free garment prevents contamination which otherwise is caused by skin and clothes to protect from dust or dirt. Therefore, it requires high performance and should function as a working clothes. Clothes are a medium between human and thermal environmental system, and it is required to study human enviroment to ensure comfortableness of clothes and to satisfactorily go along with enviroment .This study investigates the physical and physiological features of dust-free garment used in the clean room at a semiconductor factory in oredr to scientifically clarify what the dust-free garmint is as well as to contribute to the design and development of high performance material and clothes. Three kinds of dust-free fabrics (DFG-I, DFG-II, DFG-III) which are being developed by a local company are used to manufacture dust-free garment. These dust-free garments are dressed and tested in such an enviroment as similar to semiconmemts with temperature at 23${\pm}$1$^{\circ}C$ and humidity at 50${\pm}$5%RH in order to investigate the thermo physiological and psychological features of human body. The results of this study are as follows. The results of this study are as follows. 1.The mean skin temperature was significantly different among the clothes, subjects and experimental time. Temperature tends to rise from the time of exercising load. Continuous motion coupled sealed clothes prevents heat transmittance, and temperature rises in the order of DFG-l, DFG-ll and DFG-lll as time course. 2.As for the skin temperature by local timperature is minimun on the head and torso and increares remarkably at the terminal part of human body. 3. As for the body mass loss was significantly higher in DFG-lll than DFG-l and DFG-ll. 4. Though there is no significant difference in the temperature within clothes among the kind of clothes temperature is 1$^{\circ}C$ higher in the back. Temperature within all the dust-free garments 29.7$^{\circ}C$ in the back and 31.3$^{\circ}C$ in the chest which belong to the comfort zone(31-33$^{\circ}C$). The relative humidity is 39.7%RH in the chest and 33.8%RH in the back which is slightly below the comfort zone(40-60%RH) 5. The thermal sensation belong to the comfort zone regardless of the kinds of clothes. The subjects feels a slight fatigue as times goes. As for the subjective sense of subjects the mean skin temperature as well as temperature and humidity within clothes show similar tendency. This means that they relate with each other.
