  • Cooling clothes especially cooling vest are being considered for as an efficient way to reduce heat strain under hot environment. But wearing ice gel or ice-based cooling vest caused discomfort to subjects due to the weight of vest. Therefore, this study was executed to find efficient cooling parts and to reduce vest weight by cooling only these parts. Two male subjects were exposed to heat(40$^{\circ}C$, 30%RH) with A type(breast+back+abdomen+waist), B type(breast+back+waist), C type(breast+back+abdomen) and D type(breast+back) cooling vest that distinguished with cooling part. The results were as follows; When subjects were C type and D type vest, sweat volume was less and skin temperature was low. Heart rate and rectal temperature were low in B type and D type. These results suggest that excessive cooling of breast and abdomen may exert a bad influence to health and cooling of back is desirable.

  • Cooling garments are being considered for reducing heat strain in hot environment. We evaluated the effectiveness of ice gel-based cooling vest in hot environment both resting and exercising. Four male subjects were exposed to heat(4$0^{\circ}C$, 50%RH) with vest or without it. The results were as follows; In case of the trial wearing ice gel-based cooling vest, total body weight loss, and local sweat volume were less than those without it. Mean skin temperature, rectal temperature, pulse, energy expenditure, temperature of inside clothes, and humidity of inside also were lower than those without cooling vest. By subjective thermal sensation, subjective humidity sensation, and thermal comfort sensation, it was proved that non-wearing vest decreased comfort than wearing that. These results suggested that wearing ice gel-based cooling vest reduced human heat strain in hot environment both resting and exercising.

  • "Caraka-sa$\d{m}$hit$\bar{a}$ (闍羅迦集)" and "Su$\'{s}$ruta-sa$\d{m}$hit$\bar{a}$(妙聞集)" are the most important medical scriptures in India and are called the three scriptures of Ayuverda including "Astanga-hrdaya-sa$\d{m}$hit$\bar{a}$(八心集)" (which integrates and summarizes internal medicine and surgery.) that is scribed in 8C. Scriptures that have been told today are deemed to be written in 3 ~ 4C. The three scriptures of Ayuverda and "Yellow Emperor's Canon Internal Medicine(黃帝內經)" are very similar in historical position, transmission and separation and addition, pattern and importance of contents, etc, from the aspect of formation and transmission of scriptures when compared with herb medicine. The characteristics that "SuWen(素問)" concentrates on medical theory and "LingShu(靈樞)" focuses on acupuncture therapy are similar with the characteristics that "Caraka-sa$\d{m}$hit$\bar{a}$" values internal medicine and "Su$\'{s}$ruta-sa$\d{m}$hit$\bar{a}$" appreciates surgery. The chapter 8 of "Caraka-sa$\d{m}$hit$\bar{a}$ (闍羅迦集)" is called as 'a volume of completion (or a volume of success)' and describes details of 'pancakarma (which means five representative treatment methods, that is successful regulations of two kinds of basti(灌腸), $\'{s}$irsavirecana(油劑), virecana(下劑), vamana(吐劑). Therefore, the author compares summery of 'internal therapy' of Indian medicine and drug treatment method with Method Of 'Sweat, Vomit And Diarrhea of the representative treatment in herb medicine, based on "RuMenShiQin(儒門事親)" of ZhangZiHe(張子和).

  • The object of this study was to help designing of well-fit and comfortable brassieres for the elementary school girls through the survey on actual condition of wearing brassieres. The subjects of investigation for this study was the elementary school girls in the province of Jeonbuk and Taejeon city. The conclusion of this study was as follows; The 40.2% of the total subjects were wearing brassieres like the 63.3% of the fourth, the 85.4% of the fifth, and the 89.7% of the sixth grade students. The main reason of non wearing brassieres was for the underdeveloped breast, and also that of wearing brassieres was for the good shape of the breast. The main types of brassieres were ranked "Tank Top type", "Mold type", and "Adolescent girl-Bra". They had started to wear brassieres by the recommendation of adults who were their mother or teachers, and usually wearing brassieres all day. They usually purchased brassieres "with mother together" or "only by their mother". The standard of choosing brassieres was also ranked by FASHION, CONVENIENCE, SIZE, TOUCH, and SWEAT ABSORPTION. The total score of satisfaction for wearing brassieres was showed "Average score" and the score higher in Jeonju and Taejeon than in Kunsan. The higher grade and fatter was showed decreasing the score of satisfaction. The higher grade became, the more various for the size and preferable a pure cotton fabric for brassieres. The favorite types of brassieres were "Sport Bra" and "Volume-up Bra". They usually purchased a little larger size than their original size of that.

  • Sasang Constitutional Medicine (SCM) is based on the theory of Sasang (Taeyang, Soyang, Taeum, Soeum) in Traditional Korean Medicine (TKM). It is hypothesized that all of the things in the material world can be divided into the four categories of SCM. We made a new attempt to combine nutritive components, and patterns in physical activities with SCM. At first, we hypothetically divided the nutrients into 4 compartments according to SCM theory, and human body composition as well. These factors could be basically related to Sasangin Exercise Treatment (SET). Therefore, we applied sasangin theory to exercise prescription. As a research method, we hypothesized that human beings' types can be distinguished by mind and body. Mind was focused on exercise psychological aspects, and body also handled by nutrients, body compositions, body shapes, and exercise physiological aspects. For application of sasang theory to the exercise prescriptions, Taeumin as a sample sasangin was selected in this study. We concluded that in perspective of general traits, Taeumin have to reduce their carbohydrate intake volume, but greatly increase their intake of vitamins, minerals, and water in daily diet. They are also recommended exercises that can increase cardiorespiratory function and make them sweat, like endurance running, hiking, swimming, cycling, etc.

  • This study was designed to investigate the expression and production of interleukin-1beta $(IL-1{\beta})$ in human peripheral blood of trained runners and untrained controls after temporary moderate intensity exercise. Male long-distance trained runners (TR) and untrained sedentary control subjects (SED) ran for 1 h at 70% of heart rate reserve (HRR). $IL-1{\beta}$ gene and protein expressions were significantly higher in TR than those with SED at all 3 intervals examined independently. Significant increases in total sweat volume and oral temperature were observed after exercise in both groups, however, there were some differences between the groups. We conclude, therefore, that sweating due to exercise is associated with increase of $IL-1{\beta}$ and it is correlated with decrease of oral temperature.

  • The purpose of this study was to investigate the attitude and wearing effect of brassiere wearing in 20's female college students. Particularly, by exploring the necessity of wearing a brassiere, the research was carried out to make it possible to use it effectively in the development of brassiere for women in their early 20s. In early 20s, the type of wearing brassiere in female college students was analyzed as three types: function-importance type, inconvenience-accept type, and wearing inconvenient type. Function-importance type, the brassiere corrects the silhouette of the upper body, has a push-up effect that collects the breast, and it was thought that it would not allow the nipple point to fall. By wearing a brassiere, there is a lift-up effect that reduces the vibration of the breast due to movement and raises the bust. Inconvenience-accept type wears a brassiere so that the breast volume can be improved and the nipple point is not visible. And they strongly agreed that the brassiere would wrap my breasts well and calibrate the upper body silhouette to make my body look pretty. However, they felt that their bust was troubled when they wore it, and they thought that their brassiere would be out of order due to their movements, so they had to wear brassiere for beauty, but they were uncomfortable. The wearing inconvenient type was analyzed as a type that the cup part was lifted, the sweat was not absorbed, and the heat was uncomfortable. It is thought that it is necessary to develop an effective brassiere for the function of raising and collecting breasts based on the body shape of women in their early 20s.

  • MFD (Make up Film Deterioration) is a gradual deterioration of applied make up and is a common problem experienced by most foundation users. Our investigation revealed that for 64% of all make up users MFD is their greatest consern is using foundations. Known that the primary cause of MFD is sebum secretion. We observed that the length of time prior to onset of MFD in people who produce high level of sebum varies significantly from person to person. This suggests that other factors besides quantity of sebum production can affect MFD. Control over this factor would, we believe, be key to developing longer-lasting makeups. We studied the relationship between MFD and skin surface conditions. Our study revealed that furrows on the skin surface affect MFD significantly. Sebum reaches the skin surface from sebaceous glands and flows along furrow on the skin. If there are many deep furrows, it takes longer for sebum to overflow. But if the furrows are few or shallow, sebum quickly overflows and spreads over the skin surface where it can degrade the make up film. Therefore even when the volume of sebum produced is the same, the rate of MFD will be different depending on the number and shape of the furrows. A longer-lasting foundation could be produced by matching personal skin condition, but this would be very difficult because individual variations in texture are very large. Therefore we approached the problem by attempting to impose sebum resistance in under make up and foundation. We have developed two new materials and make up products based on our theory. A new fluoroalkyl acrylate-methacrylates copolymer designed for incorporation in under make up is extremely sebum resistant and sweat proof. Another new acrylate polymer designed for inclusion in foundation absorbs sebum and changes to a solid. Usage tests confirm it is possible to reduce MFD by using under make up and foundation which incorporate our new materials to cover where skin furrows are few or shallow
