The purpose of this research was to device thermal comfort model for radiation power plant workers in protective clothing. Three fabrics commonly used in protective workwear were made into coveralls of identical design and were evaluated by adult healthy males in four simulated work environment. It was investigated between the physiological response and subjects comfort according to environmental variance and clothing types. The of simulated work enviro mensent was controlled under four different humidity and temperature of each type. (Temperature 20±1℃, RH 40∼70%±5%, Temperature 30±1℃, RH 40∼70%±5%) An index of physiological response was connected with the thermal comfort designed. Mean skin temperature, skim temperature, Axillasy temperature ear canal temperature, clothing climate, total sweat, blood pressure, and R-R interval were be evaluated. Skin temperature difference ocurring during exercise and rest were significant only with respect to time and regions of the body, This despite physical differences in the three coveralls, particulary mass statistically experiment. Also, an index of subject wearing sensation was designed for thermal comfort after investigation determined the kind of clothes and the type of environment. As a result of this research, two types of multiple regressions was deviced to estimate thermal comfort of the protective clothing.

This study finds information about the image and improvements of hiking gear and examines the influence of heat moisture, psychology, tactile sensation, and mobility/pressure related properties on wear comfort. The relationships of the four related properties and personal characteristics (such as sex, age, BMI and sensitivity) were also checked. Questionnaires were distributed to 400 people in their 40s and 50s; subsequently, 260 were used for data analysis. The questionnaires were comprised of questions about the general hiking characteristics, images and improvements in hiking gear, influence of the four properties on wear comfort, and demographic characteristics. Data were analyzed by frequency analysis, correlation analysis, ANOVA, T-test using SPSS 21 IBM for Windows. The results of this study are as follows. It was shown that people in their 40s and 50s usually went hiking two to four hours with friends or family once to three times a month. Jacket had the largest number of wearing frequency, followed by pants, t-shirts, and inner wear. Consumers' images of hiking gear were positive and the demands for improvements in hiking gear were price, unique design, and vivid color. The order of influence of the four properties on wear comfort was heat moisture, mobility/pressure, tactile sensation, and psychology related properties. The four properties of wear comfort were not influenced significantly by consumer sex, age, BMI, and sensibility.

In this research in order to grasp the recent research trends of clothing comfort in Korea, 584 theses have been analyzed about the forms, contents and subjects of their researches which have been published in four Korean Journals from 2000 to 2012. The results are as follows: Many of the research contents were on the clothing comfort and environmental adaptation clothes in all journals. Handle, skin temperature, clothing pressure and working clothes showed the highest frequency ln the key words. The review studies were the fewest, and experimental or survey researches were largely conducted. The research forms showed the significant differences according to the research contents. The subjects were largely focused on those aged from 18 to 29, and among the research subjects on clothing comfort, female were more than male. However, in the researches on clothing quantity and clothes wearing conditions, many of them were the studies whose subjects were both men and women. The male and old subjects increased more and more. The number of the theses in the field of clothing environmentology showed the gradually increasing tendency. The most rates were the theses on clothing comfort, but as the number of those on environment adaptation clothes increased more and more, the research contents in the two fields showed much the same. Though the attention to aging and smart clothes is increasing, the research on this is very few. Therefore, it is thought that the study on this field will have to be conducted actively.

This study is to provide basic data for the development of domestic ready-made shoes industry by illustrating any problem in regards to the ready-made shoes for ordinary salary men through looking into its uses and gratifications. Subjects for this study were in between twenties and sixties by applying convenient random sampling method, which was done in January to February, 2001. The results were as follows: 1. General foot shape of subjects was that foot breadth was wide whereas instep height was average. In regards to the metamorphic parts of foot, the most metamorphic part was the fifth toe which could be occurred by disagreeable shoes to foot. 2. General salary men (69.5%) wear the formal shoes and their wearing time per day is over 10 hours (49%), which illustrates that more suitable and convenient functional shoes needs to be developed. 3. Almost of subjects tended to purchase ready-made shoes, and their concerns to be considered when to purchase ready-made shoes were its size and solidity. This finding suggests that the size specification of the ready-made shoes needs to be more specific in terms of its length as well as foot breadth. 4. The most unsatisfied point on the ready-made shoes was the foot breadth. According to the Crosstabulation analysis on the discomfort part and the foot breadth, there existed a significant correlation between the discomfort part and the foot breadth (p$\leq$0.05). The above results make clear that overall salary men have complaints on the ready-made formal shoes in terms of its size and wearing comfort level. This suggests that the subdivision of the shoes size specification needs to be developed to improve the wearing comfort level.

This study investigates actual wearing conditions and satisfaction based on qualitative research for rifle shooting clothing. The survey was conducted in two ways: in-depth interviews of 4 rifle shooting experts and subjective questionnaires for 18 active rifle shooters. They agreed on the importance of rifle shooting wear to minimize body sway and contribute to a balanced body posture. Most rifle shooters purchase made-to-measure rifle shooting clothing at a domestic store, but the clothing often needs extra adjustments due to an uncomfortable fit. Current fabric for rifle shooting clothing consists of a cotton canvas with a polyester mix; however, rifle shooters are unsatisfied with its stiffness in hot and wet conditions. Due to the specific fabric features, rifle shooting clothing should not be washed despite year-round use that represents another point of dissatisfaction. Rifle shooters always wear specially designed underclothes to improve shooting skills and comfort sensation. In conclusion, it is necessary to develop well fitted and comfort rifle shooting clothing that could improve shooters skills based upon this study.

This study conducted a survey to find out atopic dermatitis patients' required performance and preference in design factors to develop spring/summer(S/S) knitwears preferred by atopic patients. On the platform of achieved information from statistical analysis, S/S knitwear samples for atopic patients were designed and constructed with cotton/Seacell(R) blended yarn, And subjective wearing sensation were evaluated comparing the samples and the commercial products made with cotton/chitosan blended yarn, trying to help producing more comfortable S/S knitwears for atopic patients. SPSS 12.0 program was used for frequency analysis, Chi-square analysis, ANOVA, and Duncan test. The result was as follows; For comfort of S/S knitwears, atopic patients most considered skin care property. Atopic patients preferred simple and basic knitwear in light color with thin and soft fabric such as plain knit. The preferred style was that 'appropriately fit with suitable ease'. They also preferred 'closed front'; 'boat neckline' and 'V neckline'; 'raglan sleeve' and 'set-in sleeve'. For hem trim, they preferred 'rib' structure. Male preferred simple and plain style with 'round collar' and 'tubular or rib trim", while female preferred sophisticated and characteristic style with 'set-in sleeve' with 'rib trim'. Under the circumstances with insufficient functional knitwears developed, this study tried to develop comfort S/S knitwears for atopic dermatitis patients and the developed knitwears showed as good as or better performance in wearing feeling, fitting, and appearance than the previously developed functional goods.

The purpose of this study was 1) to estimate the improvement of thermal storage/release and moisture transport properties of PEG-treated acrylic athletic socks and suggest the optimum add-on for PEG treatment, 2) to investigate wear performance of untreated cocks and two kinds of socks treated with PEG of minimum and optimum add-on respectively, and 3) to consider the effect of thermal storage/release and moisture transport properties of PEG- treated socks on the wear performance and the subjective comfort zone. Thermal activities of specimens treated by PDC were evaluated on a DSC by measuring the heat of fusion on heating and the heat of crystallization on cooling. Moisture regain, absorption speed, wickability, water retenti on value, and water-vapor permeability were measured. In the wear trials that the subjects performed a subsequent exercise protocol wearing three differently treated socks in a conditioned environment ($14\pm2^{\circ}C$, 65$\pm$2% R.H.), microclimate temperature and humidity, and subjective wear sensations including thermal sensation, wettedness, softness, fit, and overall comfort were obtained. PEC-treated specimens with more than 20% add-on showed thermal storage on heating and thermal release on cooling by a DSC and the heat contents of treated ones were generally proportional to the add-ons. Moisture transport properties were highly improved after PEG treatment and increased rapidly with increasing add-on. The tendencies were, however, relaxed above 50% add-on and the treated knits were much stiffer above that add-on. In the wear trials of untreated, PEG add-on 20%, and 50% acrylic socks, the changes of microclimate temperature of 50% socks were significantly less than that of 20% socks. PEG add-on 50% socks showed significantly less changes of microclimate humidity than other two kinds of socks. Three kinds of socks showed significant differences in overall comfort and add-on 50% socks were accepted more comfortable than other two kinds of socks. Comfort zone of foot was extended after PEG treatment on socks and it implied that the subjects wearing PEG- treated socks felt comfortable in wider ranges of microclimate temperature and humidity.

For this study, we developed clothing in which textile materials that were excellent weather control function for the cold environment and we performed the human subject test with developed clothing to determine the thermal comfort. We used 2 clothing samples developed (A and B, hollow yarn+moisture absorption/quick drying yarn, 3 layers, high stretchable, heat reflection film and lamination treated) and a control sample (Ctrl.) for the human subject test and 8 adult males were used as a human subjects and environmental conditions of chamber were $0{\pm}1^{\circ}C$. $50{\pm}5%RH$, 0.3m/sec. The results were as follows: The average skin temperature and hand, thigh temperature of B were higher than B and Ctrl. (p<.05). The micro-climates of B were near to thermal comfort range which is $32{\pm}1^{\circ}C$ and $50{\pm}10%\;RH$. The chest temperature of B was significantly higher than others (p<.05). The relative humidity of B was lower than others and kept stable rather than others. The thermal sensation of B was near the "neutral" and was significantly different from Ctrl. (p<.01) and the weight loss of B was lower than Ctrl. (p<.05). The counting task and hand temperature was positively related and the counting task value of B and A is bigger than Ctrl. and that of A was bigger than Ctrl. (p<.05).

The purpose of the present study was to suggest the design requirements for Korean naval duty uniforms by evaluating the physiological and psychological comfort while wearing the uniforms. Two sets of wear trials were conducted with summer uniforms(eight young males) and winter uniforms(seven other young males). The summer wear trial consisted of 10-min rest, 60-min exercise, and 10-min recovery at an air temperature($T_{air} $) of $33^{\circ}C$ and 62%RH, followed by 10-min recovery at a $T_{air} $ of $23^{\circ}C$ and 64%RH(total 90 min). The winter wear trial consisted of 20-min rest at $T_{air} $ $20^{\circ}C$ and 55%RH, 25-min rest, 30-min exercise, and 35-min recovery at a $T_{air} $ of 0oC and 43%RH(total 110 min). Rectal and seven skin temperatures, clothing microclimate, heart rate, oxygen consumption, total sweat rate, and subjective perceptions were measured during the wear trials. By evaluating the experimental results from the wear trials, we extracted the following psycho-physiological design requirements to improve the current Korean naval uniforms: (1) It is important to maintain the skin temperatures within their comfort range, which depends on the body region (higher than $30^{\circ}C$ in winter, but less than $35^{\circ}C$ in summer). (2) In summer, the feet should be protected from the high heat of the ship floor surface. (3) In summer, sweat from the back should be sufficiently absorbed and allowed to dry quickly.

The purpose of this study was to examine the thermal comfort characteristics of the garments for school, textile and bank worker's uniform. The garments selected for this study were frequently used in Taegu area in terms of design and material used for making garments by the survey for the study The human subject tests were performed to determine the thermal comfort characteristics of garments including thermal, humidity, and wearing sensation and the data were analysed statistically. The results of the study were as follows: 1. According to the result of the survey jacket was mostly used as a school uniform for both male and female high school students. The survey showed that 93% of male students wore 'neck T-shirts' and dimensional fitness for the school uniform got suitable at 2~3 grade high school students. In terms of human subject tests, most students rated 'uncomfortable' in wearing sensation of their school uniform. One of this reason was due to the humidity sensation and air velocity sensation. Level of significance of the thermal sensation for gender difference was higher in hands and feet of the subjects than in chest and thigh of them. 2. According to the result of the survey jacket with zipper was mostly used as a textile worker's uniform. The result of the survey indicated that some textile workers are wearing their inner wear (38.7% for upper and 46.6% for lower). In the human subject tests, about 50% of subjects rated 'comfortable to slightly comfortable' for wearing sensation of the textile worker's uniform. It showed that the female subjects of the humidity sensation was rated higher than the male subjects of the humidity sensation, while the male subjects of the thermal sensation was rated higher than the female subjects of the thermal sensation. There was a closer correlation with the subjective thermal sensation for textile worker's uniform in center parts of the subjects such as back and waist than exposed parts. 3. The result of the survey showed that 70% and 23% of the female banker uniform were blouse and jacket, respectively and 75% and 25% of the male banker uniform were jacket and T-shirt, respectively. All interviewee rated trousers and skirts that were used for their lower. 4. The result indicated that 50% male and 67.7% female subjects for the banker uniform rated 'slightly comfortable for the comfort' sensation. 50% male subjects rated 'neutral' and about 50% female subjects rated 'slightly warm to neutral' for the thermal sensation. In addition, The result showed that 75% male subjects for both upper and lower rated 'neutral' for the humidity sensation and also 75% female subjects rated 'neutral to slightly dry'. Thus, there was no significant different between gender. 5. In the thermal sensation of the subjects for the banker's uniform by parts, 50% subjects rated 'neutral' for their body parts, including head, neck, back, waist, hip, lower arm, and thigh. The extremely cold parts were hands and feet for both male and female subjects.
