Menstruation being an inevitable phenomenon for every women, reducing the discomfort during the menstruation period is one of the important issues for women's well-being. This study was conducted through user evaluations on disposable pads and reusable pads to comprehend the discomfort factors of the sanitary pads and to provide basic information for improvement. Negative symptoms of the reponses on menstruation outnumbered the positive aspects, and the results suggested that menstruation period was perceived as a painful experience to women. There were difference between the negative and positive responses regarding the designs, functions, fittings, wearing sensations. and disposabilities of disposable pads and reusable pads. While disposable pads had the strength of convenient use, it had the weakness of wearing sensation, and while reusable pads had the strength of wearing sensation, it had the weakness of inconvenient keeping. When designs reflecting these results are made, it is expected to bring a synergy effect by bringing both a more pleasant menstruation period for the consumers and eventual profit to the manufacturers.

Hot and humid weather in summer generally brings about discomfort. Experiments on which relative humidity makes effects on the comfort sensation were performed to the young and the aged using sensation vote. From July to October 1996, seven college students and eleven aged people were exposed for 2 hours under six different conditions in the Pukyong National University test chamber so as to determine the effects of relative humidity on thermal and comfort sensations. Subjects were wearing same clothes, and the mean clo value was 0.5. The mean radiant temperature was equal to the air temperature and air velocity in the occupied zone around 0.lm/s. In the experiments, it was found that discomfort could be largely reduced when the humidity is controlled to low values in the settled high temperature.

Slashes, deprived from the Crusaders' military uniforms, take their places among the fashion terms in modern fashion, and they are represented with some techniques such as fraying fabrics or making holes. Slashes are also used in various ways across all the fashion areas including clothing to accessaries. Slashes, which were once used to represent a solid body and to make a body move suitably, are used not only to express the formative of clothing but also to allow wearing sensations and functionality to wearers depending on their daily lives and the movements of their activities in modern fashion design. Optical illusions of fashion, image variabilities, functionality and ornamentation, and design principles, which were once represented with materials, colors, and details mainly used in fashion designs, are represented using slashes in modern fashion.

This study was to investigate the distribution of the garment pressure in daily wearing and in ordinary posture. Ninety-nine college women students majoring the fashion were participated for this study. IBP questionnaire, garment pressure, personal preferring pressure sensations(questionnaire), and subjective garment pressure sensations were measured. There were no significant differences between the data of 2003 and those of 2005. Participants preferred T-shirts and jeans and also preferred slightly fitted style to the loose style. They were classified with the high garment pressure group and the low garment pressure group. Garment pressure from lower garments were usually higher in the high garment pressure group than in the low garment pressure group. There was no significant differences in the upper garments weights between two groups. The lower garments weight of the high garment pressure group showed $533.3{\pm}182.11g/m^2$ and that of the low garment pressure group was $453.4{\pm}181.6g/m^2$. There was a significant difference in the lower garments weight between two groups(p<.01). In a standing posture, there were no significant differences among the distribution of garment pressure. There was a significant garment pressure differences between sitting on a chair and sitting on the floor(p<.001). Participants included in the low garment pressure group felt a higher garment pressure than participants included in the high garment pressure group.

The purpose of this study was to evaluate thermal properties of soccer wear with different materials and designs. As a beginning step, the questionnaire survey about the actual condition of soccer wears was conducted. with the results of the questinnaire, two soccer wears with new material and design that were improved in tactile sensations, absorption and ventilation were developed. We evaluated thermal and subjective responses of subjects wearing Korea national soccer team uniform in 1998 World Cup (Uniform 98), soccer wear with new material and same design(New II) and with new material and new design(New I). New I was made with mesh in armhole for improving ventilation. Rectal temperature, skin temperature, clothing microclimate, and heart rate were measured in climatic chamber test(twelve times) and field test(eighteen times). The results were as follows. 1. As the results of the climatic chamber test, rectal temperature was lower in New I and New II than Uniform98, and mean skin temperature was lower in New I than Uniform 98 and New II. Heart rate was lower in New I than New II, and total body weight loss and local sweating were not significantly different by soccer wears. 2. As the results of the field test, rectal temperature was lower in New I than Uniform98 and New II. Mean skin temperature was lower in New II than Uniform98 and New I. Clothing microclimate temperature was lower in New II than Uniform98 and New 1, and clothing microclimate humidity was lower in New I, New II than Uniform 98. Heart rate was lower in New I than Uniform 98, New II and total body weight loss and local sweating were lower in New I, New II than Uniform 98. In conclusion, New I using new design using mesh in armhole and new material using sweat absorbent finishing was excellent from the point of view of physical responses, ventilation and sweat absorption.

The purpose of this study was to investigate the effects of two kinds of underwear material on subjects exercising and resting in an ambient temperature of $20^{\circ}C$, a relative humidity of 60% and an air velocity of 0.13m $see^{-1}$. Two kinds of underwear ensemble were tested, differing in their hygroscopic properties: 100% wool (W) with higher moisture regain and 100% cotton (C) with lower moisture regain. Five young females served as subjects. The experiments comprised two repeated periods of 15 min exercise on a treadmill with a speed of 6km $h^{-1}$ followed by 10 min rest. The main results were as follows: 1) Mean skin temperature was significantly higher in W than in C throughout the whole experimental period (p<0.05). 2) The temperature and humidity of the microclimate between the skin and underwear provided by the first layer of clothing was higher in W than in C (p<0.1 and p<0.05, for temperature and humidity, respectively). 3) Heart rate was significantly higher in W than in C (p<0.05). 4) Subjects felt warmer during the second exercise session when wearing wool rather than cotton (p<0.05), and they also reported more increased wetness during the second exercise and rest periods in W than in C (p<0.05). These results suggest that underwear made of wool with higher moisture regain might not act as effectively as cotton to transfer exercise-induced heat from the body to the surrounding air when light exercise is taken in a thermally-neutral environment.

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.

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.
