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.

This study examines the exposure effects of the brand of fashion manufacturers on the brand attitude of consumers towards the private brand of fashion retailers. In addition, it investigates the exposure effects of the brand of fashion manufacturers on the brand attitude of consumers towards the private brand of fashion retailers based on the sensitivity of consumers as related to the brand. Data are analyzed by a reliability analysis, a factor analysis, the correlation analysis, t-test, and one-way ANOVA. The main results are summarized as follows. First, when the private brand of fashion retailers (Perry Jensen) was shown to customers, three groups ('PB without exposing the brands of fashion manufactures', 'PB with exposing Galaxy', and 'PB with exposing Parkland') revealed statistically significant differences in consumer purchase intentions as well as brand preferences to the PB products of fashion retailers. The group of 'PB with exposing high-sensitive Galaxy group' showed an overall higher brand attitude than the other two groups-'PB without exposing the fashion manufactures' brands' and 'PB with exposing low-sensitive Parkland'. Second, in comparison with the effects of the brand sensitivity of each group, the group with the higher brand sensitivity showed statistically significant browsing intension as well as purchase intention on both brands of fashion manufactures (Galaxy and Parkland).

This study identifies Japanese study content on heat stroke prevention measures using clothes, provides basic data for quantitative wearing assessment studies, presents a developmental direction for those, and helps invigorate further research. Studies were collected concerning clothing-based heat stroke measures in order to analyze the following factors: current status of heat stroke by industry and working environment, heat stroke and body cooling method, clothing microclimate and air circulation in a hot environment, hot environments and wearable sensors, and heat stress reduction and skin exposure. The current WBGT standard does not consider the diversity of wearing clothes according to the working environment. Therefore, it is preferable to add a correction value in consideration of design, materials, and ventilation to prevent heat strokes. For the heat stroke and body cooling method, wearing water-perfused clothing is effective to reduce heat stress and maintain exercise ability. Changing the material and design of clothing or wearing air-conditioned clothing can improve ventilation and the clothing microclimate. However, further evaluation is needed on the effectiveness of air-conditioned clothing as a heat stroke prevention product. The measurement method using a wearable sensor can provide real-time data on the body response due to working in a hot environment. Therefore, it is an effective alarm for heat stroke. Skin exposure area and heat dissipation efficiency should be considered to prevent heat stroke. Reducing the covering area by exposing the head, neck, and limbs, and wearing breathable material can prevent heat stroke from increased body temperature.

A study was conducted to investigate the effect of cooling hands of feet on human thermoregulation in the cold. Eight young (22$\pm$1 yr) and eight aged (69$\pm$4 yr) men volun-teered as subjects They stayed at 1$0^{\circ}C$ in the supine posture during the experiment which included hands or feet exposure to the air for 20 minutes. Hand Exposure (HE) and Foot Exposure (FE) were conducted in radomized order and the baseline was kept before HE and FE. Core temperatures, limb skin temperatures adn thermal sensations were measured. Obtained data were analyze using t-test and correlation. Rectal and esophageal tem-peratures increased in the young (YG) and in aged (AG). Change rate of esophageal temperature (Tes) was maintained higher during FE than HE while rectal temperature showed no differences between YG and AG, and between HE and FE. Hand and foot skintemperature in YG and AG decreased similarly during HE and Fe. Forearm skin temperature during HE decreased while leg skin temperature during FE showed no change HE and Fe. It was concluded that the lower cooling. Furthermore, the increase of Tes was greater in young men than aged men. It is also suggested that the wearing behavior can be differently modified between young and aged men.

This study aims at examining how male college students' extent of mass media exposure affects their sociocultural attitude toward appearance and appearance orientation. It also investigates how these variables show difference depending on the individual's self-efficacy. For the study, data were collected from 397 male students by means of stratified random sampling. The results are as follows: 1. Male college students 'sociocultural attitude toward appearance was shown in two factors of appearance internalization and appearance awareness. Appearance orientation was shown in two factors of interest in appearance and interest in body weight. 2. Male college students were exposed to mass media in order of videos, movies, TV entertainment shows, music and movie magazines. The influence of video media was strong. 3. Male college students' extent of mass media exposure exerted indirect influence through sociocultural attitude toward appearance rather than exerting direct influence on appearance orientation. 4. Male college students' appearance orientation varied depending on the extent of self-efficacy, and higher self-efficacy showed higher appearance orientation and appearance attitude. Especially the group with higher self-efficacy showed higher appearance attitude when the extent of exposure to mass media increased.

The purpose of this study was to examine the differences of appearance management behavior and body exposure attitude according to sex role identity. The method of this study was a survey research method by questionnaire. The subjects were 632 college students (male: 302, female: 330) living in Seoul area. The data were analyzed by SPSS program. Analysis methods used were frequency, factor analysis, Cronbach's $\alpha$-reliability coefficient, one-way ANOVA and Duncan's multiple range test. The subjects were divided into 4 types of sex role identity: androgynous, masculine, feminine, and undifferentiated type. The female androgynous group had skin care the most, while the male androgynous type had clothing management and weight control the most among the 4 types. Both male and female androgynous groups had hairstyle care the most. Both the male and female masculine groups wore chest exposing clothes the most, while the female masculine type wore shoulder exposing and leg exposing clothes the most. The female androgynous group showed the highest appearance management expenses.

Social reactions to body exposure in American leisure wear (bathing suits, shorts, and halters) in the 1930s were analyzed to provide an understanding of the process of adopting more abbreviated and less-occasion specific styles of garments in women's fashion. The research questions were as follow: How did women expose their bodies in leisure wear during the 1930s? How did the social reaction to women's body exposure in leisure wear change throughout the 1930s? How did the body exposure in women's leisure wear play a significant role in the history of women's fashion? Primary sources were collected from issues of The New York Times published in the 1930s. Topics including dress, fashion, ethics, social ethics, and sexual ethics, were reviewed in The New York Times indices. The findings were analyzed and interpreted with reference to secondary sources that included books and research papers. The results showed that the body exposure of the styles as well as the place where these styles were worn was a public issue. Women were criticized and regulated for body exposure as well as for wearing bathing suits, shorts, and halters on the streets. However, the social regulations that restricted bathing suit styles almost disappeared by the end of the decade. This represented the change of social expectations toward body exposure in the 1930s. In addition, reports of laws that forbade the wearing of bathing suits, halters, and shorts outside of beaches, pools, and parks indicated women's increased attempts to expose their bodies in public places. However, reactions to women's body exposure in leisure wear changed to accept more flexibility in the social customs throughout the decade. These phenomena were a partial step toward the popularization of less occasion-specific styles - sportswear - that took place in the 20th century.

This study investigates the differences between purchasers and non-purchasers of naturally dyed-products in the hobby/leisure, media exposure, usage of media program type, and information sources about naturally dyed-products. Data were collected from a total 213 Korean females ranging from 20 to 59 years old, and in data analyses, there were partially significant differences between the two groups. Compared to non-purchasers of naturally dyed-products, Purchasers of those ones were more interested in traditional fields and nature. They are also more exposed to newspapers and less exposed to TV. Purchasers used more informational and educational programs as well as personal and commercial information sources (store visual presentations and sales persons) than non-purchasers. However, the differences between these two groups were not significant in the interests of fashion/cooking and sports, Internet exposure, entertainment programs and public/commercial information sources about naturally dyed-products. Marketers can use the results to access the market of naturally dyed-products for promotion.

This study was conducted to investigate the thermoregulatory characteristics of feet and legs by comparing with the physiological responses according to the covering parts of lower limbs. Five healthy female subjects wore three types of clothing-covered legs and feet(LF-C) with long trousers and socks exposed the legs(L-E) with half trousers and socks and exposed the legs and feet(LF-E) with only half trousers-when the subjects rested at $25^{\circ}C$ and were exposed to 18$^{\circ}C$ for 90 min. Rectal temperatures (Tre) were maintained higher in LF-E than L-E and LF-C at both environments. Decreases of The after exposure to 18$^{\circ}C$ were significantly smaller in LF-E than L-E and LF-C and almost same in L-E and LF-C Heat production in both environments increases of heat production and weight loss after exposure to 18$^{\circ}C$ were not significant among three types of clothing. From these findings it would be suggested that the legs would play the little role of voluntary thermoregulation as vasoconstriction and the role of the legs depend on thermal conditions of feet while the feet play the positive role of voluntary thermoregulation in terms of heat conservation in cool environment.

Objectives: The purpose of this study is to assess the exposure level to dust and airborne microorganisms among employed workers in a clothing shopping center. Materials and Methods: On-site investigation of a clothing shopping center was performed between October and November 2012. The hazardous substances measured in this study are particulate matter(Total dust, respirable dust) and airborne microorganisms (Total airborne bacteria, total airborne fungi). Results: The highest geometric mean levels of particulate matter(total dust, respirable dust) for personal sampling were $1.735(SD:0.883)mg/m^3$ for total dust and $0.0711(SD:0.008)mg/m^3$ for respirable dust, respectively. Those for area sampling were $0.625(SD:0.091)mg/m^3$ for total dust and $0.0718(SD:0.012)mg/m^3$ for respirable dust, respectively. The highest geometric averaged concentrations of airborne microorganisms(Total airborne bacteria, total airborne fungi) were detected at $1,181(SD:105)cfu/m^3$ for total airborne bacteria and $683(SD:114)cfu/m^3$ for total airborne fungi, respectively. Concentrations of particulate matters and airborne microorganism in clothes shopping center did not correlate significantly with environmental factors such as temperature or relative humidity. Conclusions: Exposure levelshave not been established for service workers. Thus, health risk assessment for this group is very difficult. Health guidelines for service workers should be established as soon as possible.
