This study investigates clothing pressure and subjective sensations in brassieres depending on breast type or bra type. The results of this study show that clothing pressure and subjective sensations were significantly influenced by breast type. The flat type breast and drooping type breast have a lower subjective satisfaction. Satisfaction for 3/4WL is the largest; however, 1/2W having low preventing breast shake and no-wire bra having low bust-up or low arrange-breast are required enhancements in bra function. The results are useful to provide basic data and produce high-quality brassieres depending on breast type.

The purpose of this study was to evaluate the effect of wearing induced micro current brassiere on the physiological responses of women. Four women participated to wear a different brassiere condition: with and without micro current chips. Subjects were carried out after wearing the induced micro current brassiere for 120minutes. Eardrum temperature, skin temperature, blood pressure, heart rate, thermal perception, humid perception, and comfort perception were obtained. The results were as follows. The brassiere with micro current chips showed better performance on weight loss than the brassiere without micro current chips. Participants in a higher level of BMI were more likely to lose greater weight. Mean skin temperatures decreased with micro current chips. Participants felt more comfortable for walking in micro current brassiere than in brassiere without micro current chips.

This study was intended to investigate the wearing conditions of shirts, and examine the preferred subjective sensation for shirt fabrics. A questionnaire survey was conducted on 469 university students (male students $45.3\%$, female students $54.7\%$) in the Cheongju area, Korea. Frequency, descriptive analysis, $\x^2$ and t-tests were used for data analysis. The results were as follows: Regardless of gender, most owned 4 shirts in the autumn, which were each worn once or twice week. Generally, patterned shirts were less favored than those with solid colors, regardless of gender, but the color of the shirts differed slightly according to gender. Most students gathered items from those displayed in the store as their source of information on shirts, and tended to purchase items worth $30,000\~50,000$ won at franchised stores with friends of the same gender. They almost always looked carefully at the size and brand, but the care label and fiber content were rather neglected during the purchase. While purchasing their shirts, the following elements were considered, in this order of importance: size; color; fitness; comfort; price; tactile sensation. Light, dense, soft, warm, wrinkle-free, dry and strong sensation of the shirt fabrics were the strongest preferences for a purchase. There were partially significant gender differences in the subjective sensation of shirt fabrics.

This study analyzed the effect of wearing a vest with an attached electric fan. Korean men in their 20s were given test "fan vests" equipped with fans on the chest, stomach, upper back, or lower back to wear. Participants wore them in a climate chamber set to replicate a summer environment (30±3℃, 75±1%RH, 0.2 m/sec). Subjective sensations and surface temperatures were measured. The attached fan on the front of the vest lowered the temperature of the vest and the skin surface where the fan was positioned, regardless of whether the wearer engaged in exercise. However, a fan attached to the lower back of the vest was effective in lowering the lower back of the vest as well as the upper back, back of the arm, and back of the neck. In addition, subjective evaluations indicated that a vest with fans attached to the stomach and lower back provided a cool sensation. However, it was confirmed that the design of an auxiliary tool capable of dispersing the weight is necessary since the weight of the fans can interfere with the comfort of wearing the vest.

Korea and Japan, neighboring two nations, have similar cultural background and complicated relations in terms of their culture and constitution. In this study, clothing microclimate and subjective sensation of Korean and Japanese subjects for Hanbok, traditional costumes of Korea, were assessed and investigated differences between them. The results of the study were as follows. For Hanbok, the temperature within clothing at the chest have significant correlations with the variables of race and elapsed time with p<0.001. At the thigh, correlations with elapsed time were significant (p<0.001). For the humidity within clothing at the chest of Hanbok, correlations with variables of race were significant (p<0.001). At the thigh, correlations with race and elapsed time were significant(p<0.001). For Hanbok, Korean group reported 'slightly warm' whereas Japanese group reported 'hot' in the thermal sensation. For the humid sensation, Korean group reported 'neutral' and Japanese group reported 'humid'. For the comfort sensation, Korean group reported 'slightly uncomfortable' and Japanese group reported 'uncomfortable'. Japanese group reported high relation with comfort sensation and humidity of microclimate.

Gaps between the upper edges of brassiere mold cups and the breasts are one of the most serious issues in realizing comfort wearing of commercial brassieres for small-breasted women. The surplus ease amounts causing the fit problem were measured from 3D wearing images of the small-breasted women's brassieres. The effect after the removing the surplus ease amounts from the upper edge of mold cup was approved by subjective wearing evaluation. Since the volume distribution of mold cup can also affect the wearing sensation of brassiere, the subjective wearing sensation was compared for two brassieres of different volume distributions, V_L, of which volume was concentrated at the lower cup, and V_C, which has the thickest part at the nipple. As the results, the suitable sensation for cup volume and the natural wearing silhouette could be accomplished by removing the surplus ease amounts from the upper edge of mold cup to reduce the gaps between brassieres and the breasts, which could be accomplished through an approach reducing the volume near the upper edge of mold brassiere cup and making the volume concentrated at the lower cup. These works provide a useful information on the design of the brassiere mold cups for small-breasted women. Moreover, modeling methods of 3D scan data and 3D printing technique for making more accurate mold cases used in this research can be helpful to develop and evaluate clothing products in future.

The purpose of this study was to evaluate the thermal and subjective comfort of various pesticide-proof clothes made from different material. Seven male adults took part in the study, conducted in a climate-chamber controlled with an ambient temperature of $30^{\circ}C$ and a relative humidity of 60%RH. The thermal and subjective responses of subjects wearing pesticide-proof clothing made of Goretex(coating treatment), polyester (water-repellent treatment), non-woven(coating) and nylon(coating) were measured. The main results were summarized as follows: (1) Change of rectal temperature and clothing microclimate were inhibited more effectively in pesticide-proof clothing made of Goretex, polyester and non-woven than nylon materials. (2) Mean skin temperature at the end of the experiment was significantly higher in subjects who wore nylon than non-woven and Goretex, and was lowest in those with pesticide-proof clothing made of polyester. (3) Change of heart rate was significantly lower in subjects with Goretex and polyester clothiing than those with non-woven, and in those with nylon, it was highest. (4) Subjective comfort was greater in subjects with Goretex, polyester and nonwoven clothing than nylon, except for thermal sensation. Thermal sensation was greater in order of polyester, Goretex, non-woven and nylon. Thus, it was concluded that pesticide-proof clothing made of Goretex, polyester and non-woven material could reduce thermal stress during the spraying of pesticides in summer.

The purpose of this study is to analyze the subjective fabric hand of sleepwear fabrics, and to assist in developing sleepwear fabrics that offer maximum comfort in wearing sensation. In general, the respondents noted that sleepwear fabrics made with polyester had better tactile sensation than those made with cotton, while satin weave fabrics felt better than plain weave fabrics. As regards the difference in fabric hand according to gender, female students responded with more receptiveness and sensitivity than male students in the category of woven fabric evaluation. As regards the same textile materials, the evaluations of female students and male students differed in fabric hand descriptors, particularly for the evaluation on cotton fabrics. Male students responded that both plain weave fabrics and satin weave fabrics were stiff while female students replied that satin weave fabrics had better tactile sensation.

This study evaluates the comfort and suitability of safety clothing. We made three safety clothes 'y', 'lg', 'lgH'. Only 'y' made with fluorescence fabric has passed International Standards (ISO 20471). A wearing test investigated the physiological response and subjective sensations at 30℃ and 50% RH, six men participated. Mean skin temperature and tympanic temperature showed significant difference with experimental course (p<.05). The micro-temperature (Tm) showed significant differences between three garments on the thigh (p<.01). When wearing 'lg', Tm was the highest. Micro-humidity indicated the interaction between clothing and the experimental course on the chest with no significant difference; however, there was a low tendency when wearing 'lgH' after the second half of exercise. The sweat rate indicated a significant difference between 'lg' and 'lgH' at 20 minutes of exercise (p<.05). Three sensations showed significant differences with the time (p<.01), there was also a tendency to feel hotter and more humid when wearing 'lg'. Skin sensation showed significant differences between pre-experiment and post-experiment (p<.05), 'y' was the most preferred. The 'lg' with long-sleeved currently worn in Korea tended to feel hotter, more humid and more uncomfortable than 'y'. It indicates that there is room for improvement in Korean safety clothing.

The purpose of this study was to compare the comfort sensation depending on four different kinds of denim blue jeans: cotton, cotton/tencel, tencel, cotton/pp. The objective and subjective experiments were conducted to measure the comfort of blue jeans. To investigate the objective comfort, physical properties related to thermal insulation, moisture properties and hand were measured. For subjective comfort measurement, 5 healthy female college students were taken as subjects. The outcomes of the experiments are as follows: The higher the air permeability and bulk density of the denim, the lower the thermal insulation, the thicker the denim, the higher the thermal insulation. Tencel blending denim showed the higher bulk density, the lower air contents, and consequently the lower thermal insulation than the other denims. Tencel showed the highest moisture regain, and cotton/tencel blend showed the highest water vapor permeability. Tencel denim had relatively better flexibility, shape stability and elastic recovery than the other denims. The total hand values of the denims by KES-FB system were not significantly different. Cotton and cotton/pp denims raised the subjects body temperature after excercise more than tencel or cotton/tencel denims. Average skin temperature was found to have a correlation with micro climate temperature and micro climate humidity. The correlation coefficients were 0.749 and 0.767, respectively. However, average skin temperatures were not significantly different among the materials. Pulse rate was found to be the highest when wearing cotton/pp and the lowest in case of cotton/tencel denim. The energy was consumed in order of cotton>cotton/pp>tencel>cotton/tencel. There was no significant difference in preference before excercise, but, after the excercise, the order of preference changed as the following; cotton/tencel>tencel>cotton/pp>cotton.
