Performances of Taekwondo fabrics were evaluated in respect of fiber component. yarn count, weave structure and wearing comfort. As a beginning step, we investigated the present situation of Taekwondo wears by questionnaire from pro and amateur Taekwondo players. Samples employed in this study were cotton/nylon blend fabric that was newly woven for this study as well as fabrics of current Taekwondo wears for sale in the market. Their fundamental properties measured were such as air permeability, water vapor transport. wickability, absorption rate, Qmax values, thermal conductivity, durability, hand value, and etc. In addition, subjective wearing sensations were evaluated using Taekwondo wears made of those fabrics. From the results of the objective measurement and the subjective wearing test, we estimated the total fitness of fabrics as a Taekwondo wear. From the questionnaire we could see that pro players and amateurs wanted highly absorbing, quick drying, and soft-tough and complained abrasive surfaces and static elasticity of current fabrics. In view of the results so far achieved, nylon blended fabrics newly woven in this study, showed better comfort-related properties from both of the objective and subjective tests. It was also represented that finer yams enhanced water absorption and touch, and fabrics with rough surface such as honeycomb weave was superior in wearing comfort as well as aesthetic appearance.

The purpose of this study was to evaluate the comfort and fabric hand characteristics of selected lining fabrics made of acetate and polyester. The comfort of the linings was determined by human subjects wearing suit blazers constructed with different lining materials in an environmental chamber controlled at $30.6^{\circ}C$ air temperature and 50% relative humidity. The hand characteristics of the lining fabrics were determined by five trained panelists using standard fabric reference samples. The effect of lining fabrics on the subjects' thermal sensations was not statistically significant. But the subjects voted warmer when wearing the polyester surah lined blazer or the polyester taffeta blazer than wearing the acetate blazers. The results of the subjective comfort evaluation indicated that, in general, the subjects rated the acetate linings significantly less sticky, clammy, damp, and non-absorbent than the polyester linings. Acetate surah was rated a little higher than the other acetate fabrics on these comfort descriptors. The results of the subjective hand evaluation indicated that the lining fabrics rated low on the geometric and mechanical hand characteristics and rated moderate on noise. Acetate surah scored the highest on most of the hand characteristics, whereas, polyester taffeta scored the lowest.

The purpose of this study is to examine and to evaluate the wearing performance of pile materials to produce velvet fabrics which have excellent wearing comfort. Acetate velvet, Cuprammonium rayon velvet were combined as textiles for clothing and acetate and viscose rayon were as textiles for lining at the environmental condition of temperature $15^{\circ}C,\;18^{\circ}C,\;21^{\circ}C,\;24^{\circ}C$, relative humidity $50{\pm}5%$ and air velocity 0.25 m/sec. Wearing comfort among 4 materials combinations(Aa, Av, Ra, Rv) was examined and compared. The results are as follows. The investigation of mean skin temperature for environmental temperature and material combinations showed that the mean temperature had a significant difference at the p<0.01 level in accordance with environmental temperature and material combinations.(Aa>Av>Ra>Rv) Moreover, in clothing climate only clothing temperature tended to increase almost linearly but at $24^{\circ}C$ there was no significant difference among textiles for lining compared with the other environmental temperatures. In subjective sensations thermal sensation and comfort sensation showed a significant difference in environmental temperatures and materials.(Aa>Av>Ra>Rv) Though a subject felt warmer, more humid, and more uncomfortable at $24^{\circ}C$ for all of the material combinations comparing with the other temperatures, there was no significant difference in materials.

The purpose of this study is to suggest sleeve cap height with a satisfying wearing sensation and appearance on jackets for women in their twenties so that high-consumer demand jackets can be produced. Five experimental jackets with sleeve cap heights of [(AH/3)-1cm], [(AH/3)-0.5cm], [AH/3], [(AH/3)+0.5cm] and [(AH/3)+0.8cm] were made for 30 subjects to try on after which the subjects were then surveyed for their assessment of appearance, wearing sensation and preference. On the basis of the results, the optimum height of the sleeve cap has been proposed along with the following contents and results of this research. 1. [AH/3] [(AH/3)+0.8cm] of sleeve cap height was assessed to beof desirable appearance. 2. [AH/3] of sleeve cap height garnered a high opinion in terms of intuitive wearing sensation, while [(AH/3)-1cm] [AH/3] were the heights with overall satisfaction of intuitive and movement wearing sensations. If discomfort in the upper sleeve at 'straight arm' posture can be tolerated, the sleeve cap height can be set to [(AH/3)-1cm]~[(AH/3)+0.5cm]. 3. [AH/3] and [(AH/3)+0.5cm] were found to have a high preference among wearers, which indicated that the women in their twenties prefer a slim type of sleeve, putting appearance above wearing sensation. Consequently, [AH/3] is desirable when appearance, wearing sensation and preference are considered, [(AH/3)+0.5cm] is fit for business uniform for static duties or formal dress focused on aesthetic impression and [(AH/3)-1cm]~[AH/3] are desirable for work clothes when considering active duties.

The purpose of this study was to better assess and understand current needs and wearing sensation, including clothing behavior for early elderly women in the Korea and USA. The subjects in this study were 135 and 173 early elderly women in the Korea and USA. This research was done by a survey method and chi-square test. The major objectives of this study were as follows; First, it was found that the early elderly women of Korea utilize mostly human information as information source when purchasing clothing, whereas those of USA mostly media information. The women of Korea were found to put most emphasis in esthetic aspects of clothing, whereas those of USA in comfort. The most frequently worn clothes by the early elderly women of Korea were jumper, T-shirt and slacks, whereas jacket, sweater and slacks by those of USA. As for skirt, flare skirt was highly preferred in Korea, whereas A-line skirt in USA. Second, regarding the wearing sensation of ready-made clothing, the wearing sensation of jacket was found to be worst on the shoulder in Korea, whereas on the waist in USA. And the early elderly women of both Korea and USA had poor wearing sensations due to the length of sleeve, of trouser, of skirt and of one-piece dress. The comparison of the clothing behavior and wearing sensation of the early elderly women between Korea and USA showed a greater difference in clothing behavior than in wearing sensation.

To study the time course of increased cold tolerance, the physiological responses were measured during the course of a 2-yr study (Feb. 1995~Feb. 1996) of four female college students, whose cold tolerance was proved to be increased through wearing cool clothing in daily life from Sep. 1994 to Feb. 1995. To determine their cold tolerance, subjects rested at 25$\pm$1$^{\circ}C$, then were exposed to 15$\pm$1$^{\circ}C$, 50$\pm$5% R.H. for 90min in Feb. 1995 and Feb. 1996. Subjects' rectal temperatures, mean skin temperatures, heat production, shivering onset, thermal sensations, and comfort showed no significant changes, when they were measured in 1995 and 1996. Based on these results, we can safely assume that mild cold acclimatization coming from wearing cool clothing lasts at least oneyear, that is until the following year. One of the possible explanations for this is that the subjects did not increase their clothing thermalresistances after the cold acclimatization.

This study aims to provide primary data regarding the thermal stress of disposable personal protective coveralls. Thermal stress and surface temperature measurements were taken among ten men wearing coveralls. The size of the ten men corresponds to a size eight in Size Korea. As a result of thermal stress, sensations of humidity and discomfort were higher when wearing Level C compared to Level D. Level D felt significant thermal stress in their upper body after exercise. However, they did not feel such stress in their lower body. Level C felt thermal stress in their upper and lower body after exercise. In addition, in Level C, the ratings of perceived exertion blood pressure and pulse rate after exercise were higher than those of Level D. Furthermore, the surface temperature of disposable personal protective coveralls among Level C was slightly higher than that of Level D.

This research aims to invest consumers' purchase behavior and preference of F/W season knit wear to prepare for basic data in producing competitive knit wear which can meet consumers' demands. The results are as follows: 1. Consumers in their twenties are largely purchasing their knit wear at bonded clothing shops, consumers in their thirties at outlet stores and consumers in their forties and fifties at department stores. As for preferred materials in knit wear, the twenties like 100% of cotton, the thirties mixed wool, and the forties and the fifties 100% of wool. Across all age groups, they prefer knit wear pattern with no figures, while they consider its design and color as important factors in purchasing F/W knit wear. 2. As for the wearing sensations of F/W knitwear of three age groups, there are not significant differences in other factors except a factor of 'jacket length'. 3. As for the fitting sensation about F/W knit wear, consumers with 'thin' somatotype feel high comfort in the factor of 'girth', while consumers with standard somatotype feel high satisfaction in the factor of 'length'.

Over the past 15 years productive BCI research programs have arisen. Current mainstream EEG electrode setups permit efficient recordings but most of electrodes has the disadventages of need for skin preparation and gel application to correctly record signals. The new gel-free probe was adapted for EEG recording and it can be fixed to the scalp with the micro needle without neuro-gel. It use standard EEG cap for wearing electrodes on scalp so it is compatible with standard EEG electrodes. A comparison between electrode characteristics is achieved by performing simultaneous recordings with the gel electrodes and gel-free probe placed in parallel scalp positions on the same anatomical regions. The quality of EEG recordings for all two types of experimental conditions is similar for gel-electrodes and gel-free probe. Subjects also reported not having special tactile sensations associated with wearing of gel-free probes. According to our results, it is expected that gel-free probe can be adapted to BCI, BMI(Brain Machine Interface), HMI(Human Machine Interface) because of its simple application and comfortable wearing process.
