Sauna, or hanjeung (汗蒸) is a physical sweating method that uses external heat to forcibly raise body temperature to treat cold damage disorders (傷寒) in traditional Korean medicine. This study focuses on the fact that the sauna was recorded as a healing and bathing method on the Vinaya Pitaka (律藏), and investigates the records of folk sauna therapy of Joseon Dynasty from the perspective of Buddhist medicine which played a significant role in ancient medicine history in Korea. Although the word 'hanjeung (汗蒸)' first appeared in "The Veritable Records of King Sejong (世宗實錄)" in the Korean literature, this study aims to confirm the possibility that the tradition of Buddhist sauna bathing has already existed since the Three Kingdoms period in Korea, based on the fact that sauna bathing was recorded in the Vinaya Pitaka and that the ancient Buddhist bathing culture was introduced in ancient Japan. In addition, the succession of the Buddhist sauna tradition by Goryeo will be traced back through the records of 1920s urban saunas in Gaesung (개성) which was the old capital of Goryeo and had a strong tendency to adhere to traditional Goryeo customs. Finally, the study tries to identify the elements of the Buddhist sauna bathing on the records of folk sauna therapy in the Joseon Dynasty. As a result, this study examines how the Buddhist sauna bathing culture in ancient Korea, which was led by medical monks, spread in the general public and influenced the folk sauna therapy in the Joseon Dynasty.

The appeal of sauna is caused by the fact that through that, one can feel Korea's unique temperament and culture; however, because of its being a public facility and flooding of businesses due to excessive supplies of various additional features such as washing, playing, eating, sleeping and health care functions, issues of social resources and environment come to the fore, so it has reached a situation of red ocean that it is difficult to enter the market anymore. Taking these into account, this study focused on developing a thermal technology and design of the housing of an environment-friendly mobile home sauna, making the most use of the sauna's fundamental purpose and settling it as a tourist product, analyzing the marketing research on the existing sauna and considering the recent housing trends and lifestyles for a new concept sauna. Thus, regarding its characteristics and utilization, it was designed smaller than $10m^2$ (3 pyeong) so that it would be easy to install in any space and convenient to move. It can be installed in separate buildings and rest spaces such as country houses, resorts, pensions, camping grounds as well as outdoor houses, custom produced for a measure of pyeong that customers want so as to match up with the Enforcement Ordinance of the Agricultural Land Act in a concept of the farmer's hut and kitchen, bathroom and bathroom can be installed inside according to an option. In addition, regarding its efficacy, in order to give environment-friendly healing effects, materials such as Hinoki Cypress, red clay and hardwood charcoal were used, a fixed indoor temperature of $70{\sim}100^{\circ}C$ was maintained by heating methods such as electromagnetic wave free, energy saving and low-power boiler, and it was made to have excellent effects on fatigue recovery, relieving stress, skin care and diet through far-infrared emission.

Atopic Dermatitis has a number of characteristic symptoms, including itchy red spots and acute rashes that can ooze fluid and/or crust over. Currently, no cure exists as the fundamental cause of Atopic Dermatitis is not yet known. In this paper, the author reports on a case study in which Atopic Dermatitis patients are successfully treated by way of sweating. The described treatment method, called Poison Extraction Method, takes advantage of medical benefits of perspiring in hot bath or sauna. It assumes that the chronic symptoms suffered by Atopic Dermatitis patients are largely due to overuse of steroid-based ointments and attempts to extract resulting toxic elements by having patients sweat in either a hot bath or sauna or both. The exact prescription for sweating depends on the severity of the symptoms of individual patients. The described treatment has been successfully tested in a clinical trial, which we report in this paper.

We analyzed the effects of regular Jjimjilbang(Korean sauna) exposure on the heat tolerance in young and old females. Subjects were young(n=7) and old(n=7) females who never had a bath in Jjimjilbang for last year. Jjimjilbang training group took a bath in Jjimjilbang once a week 19 times. Jjimjibang expsure was limited three times per day, Jjimjil were taken free way. To prove the effects of the heat tolerance, Subjects were exposed to hot and humid air$(40.0{\pm}0.5^{\circ}C,\;60{\pm}5%RH)$. In the condition, subjects were taken a foot bathing$(40.0{\pm}0.5^{\circ}C)$ and simulated for 30 min., and rectal temperature, skin temperatures, clothing microclimate, blood pressure, total body weight loss, local sweat and subjective sensation were measured. The results are as follow: Rectal temperature, skin temperatures, clothing microclimate, total body weight and subjective thermal comfort sensation were decreased gradually(p<.001). Local sweat of upper arm was decreased(p<.01). In conclusion. the regular Jjimjilbang exposure has positive effects upon improvement in regulation of body temperature, especially in heat tolerance.

Recently, buildings with transparent glazing on exterior walls have increased. The transparent glazing on exterior walls gives an impression of opening through introducing external environment's elements to inside of the building, and has various merits and so on, but has defects in controling indoor environments. Especially, the excess of solar radiation in summer increases cooling load causing discomforts to occupants providing radiant environment with high temperature. Cooling load mainly depends on electricity comparing to heating load and intents to centralize specific time. So it is necessary to work out a countermeasure. In this study, showed P building with transparent glazing on exterior walls as a case, investigated indoor thermal performance, numerical analysis of P building in summer through comparing dry-sauna which is represented as radiant environment with high temperature. In the results of this study, transparent glazing space has radiant environment with high temperature such as dry-sauna because of the excess of solar radiation. Accordingly countermeasures are considered in building planning. As concrete methods, there are adiabatic effects using double glazing, use of sunscreen, blind, ventilation facilitation using natural draft, decrease of surface temperature through evaporation cooling and cooling coils.

We analyzed the effects of regular Jjimjilbang(Korean sauna) exposure on the physiological responses in seven elderly farmers(Male=3, Female=4). Jjimjil training group took a bath in Jjimjilbang 8 times twice a week. Jjimjibang exposure was limited three times per day. Rectal temperature, total sweat rate, body fat (%), blood pressure, pulse, $Na^+$ concentration in sweat, and subjective sensation were measured during Jjimjil training exposure. The results are as follow: During Jjimjil exposure, changes of rectal temperature in male farmers were more stabilized than female farmers. The gradual decrease in total sweat rate and Na+ concentration in sweat was observed in both sexes. After Jjimjil exposure, the decrease in blood pressure was observed in both sexes, but not observed changes according to regular Jjimjil exposure. Subjective thermal comfort sensation was changed positively. In conclusion, the regular Jjimjil exposure has positive effects upon improvement in regulation of body temperature, blood pressure, and $Na^+$ concentration especially in heat tolerance.

Imported China Jades are mostly talc and serpentine groups, and that's occured troubles for our health and life of living organism. Serpentine is a group of common rock-forming minerals having the formula:(Mg$.$Fe)$^3$Si$_2$O$\_$5/(OH)$_4$. Sometime, simulated by nephrite or jade and translucent varieties we used for ornamental and decorative purposes. But it's forbid by heating materials for sauna and heating mats etc. that reason are it's occured asbestos dusts(chrysotile dusts) easily by the beating operations.

Measurement of xenon radioisotopes from nuclear fission is a key element for monitoring underground nuclear weapon tests. $^{131m}Xe$, $^{133}Xe$, $^{133}mXe$ and $^{135}Xe$ in the air can be detected via low background systems such as a beta-gamma coincidence counting system. Radioxenon monitoring is performed through air sampling, xenon extraction, measurement and spectrum analysis. The minimum detectable concentration of $^{135}Xe$ can be significantly variable depending on the sampling time, extraction time and data acquisition time due to its short half-life. In order to optimize the acquisition time with respect to certain experimental parameters such as sampling and xenon extraction, theoretical approach and experiment using SAUNA system were performed to determine the time to minimize the minimum detectable concentration, which the results were discussed.

We analyzed the effects of regular Jjimjilbang (Korean sauna) exposure on the cold tolerance in young and elderly females. Subjects were young (n=7) and elderly (n=7) females who had never had Jjimjilbang exposure experience. The Jjimjil training group was exposured in the Jjimjilbang 19 times per week. Jjimjibang exposure was limited to three times per day. Jjimjil activity was taken freely. To prove the effects of the cold tolerance, subjects were exposed to cold air ($12{\pm}1^{\circ}C,\;60{\pm}10%$RH). In these conditions, subjects were exposed for 30 minutes at which time rectal temperature, skin temperatures, clothing microclimate, energy expenditure, blood pressure and subjective sensation were measured. To prove the effects of the local cold tolerance, vascular hunting reaction was observed measuring the finger skin temperature while the left middle finger tip was immersed in cold water of $0^{\circ}C$ for 30 minutes. The results are as follows. According to repeated Jjimjil exposure, rectal temperature changes, peripheral temperature and energy expenditure were increased gradually in the cold climate chamber. Blood pressure, subjective sensation and vascular hunting reactions did not show any significant difference. In conclusion, regular Jjimjilbang exposure has negative effects on the ability of the body to improve its regulation of temperature especially in cold tolerance.
