The purpose of this study was to investigate physiological responses such as rectal temperature, skin temperature, micro climate, sweat rate and subjective sensations using cold protective clothing with five different clo value. The clo value was measured by thermal manikin in windless condition. Healthy five 20's males volunteered as subjects for wearing trial experiment. The climate chamber was controlled at $50^{\circ}C$, 65% RH. The experiment consisted of repeated exercise and recovery periods. We found that the higher clo value has, the higher mean skin temperature, micro climate and sweat rate show. They felt warm and wet with higher insulation clothing. Thermal comfort increased in the last recovery period after exercise. There was significant difference between five cold protective clothing. In correlation analysis of clo value, it showed that correlation coefficient(r) values were more than 0.8. Therefore, in terms of clothing insulation, we found that correlation between thermal manikin experiment and wearing trial experiment was high. Clothing insulation could be variable according to many factors such as body movement, covering area, clothing gap, layering and design. Considering the body movement, we thought that insulation measurement need to carry out both thermal manikin experiment and wearing trial experiment.

The purpose of this study was to investigate the wearing sensation and satisfaction of high school girls winter uniform' jacket. The subject participated in the study were 599 high school girls attending four different schools. The fabrics were divided into two parts of stretch and non-stretch woven fabrics. The results were as follows: 1. The high school girls showed body image distortion that she recognized herself as fatter than her real body type. Especially, this was severe in the slim body type. 2. In the aspect of the satisfaction for uniforms' jacket made with stretch fabric and non-stretch woven fabric. the elastic fabric was more satisfied than the non-stretch one because its width and length was shorter and fitter than non-stretch one. 3. When they wore the school uniform jacket, the wearing sensation of one made with stretch and non-stretch woven fabrics showed significant differences in arms hole when raising hands, front bust when carrying backpack on their back, backs while studying at desks, the upper arms and the elbows. 4. As for the alteration of school uniform jacket, the non-stretch woven fabric was appeared to be altered more than the stretch one.

Objective: The purpose of this research was to establish the differences of ground reaction force variables and sensations according to the foot types and the structures of the inner arch support band during $2^{nd}$ vertical ballet jump. Method: 12 Female ballet majors in their twenties who have danced for more than 10 years and had no injuries were selected for this research. Independent variables consist of the foot type (pes rectus, pes planus) and the structure of the inner arch support band (no band, x-shaped, linear shaped). Dependent variables consist of ground reaction force variables and relative wearing sensation. Results: The impact decreased the most when x-shaped bands were used on pes rectus and rigid pes planus. When linear-shaped bands were used on flexible pes planus, the impact decreased. Conclusion: The bands also helped reduce the impact on pes rectus. Furthermore, it is clear that according to the foot type, the impact reducing band structures perform differently. The inner arch support bands were necessary for jump training for any foot type.

The physiological significances of the upper and lower body on thermoregulation and sensation were studied in this paper. Experiments were carried out on 4 females in a climatic chamber conditioned at 1) $25^{\circ}C\rightarrow35^{\circ}C\rightarrow25^{\circ}C$, 2) $25^{\circ}C\rightarrow15^{\circ}C\rightarrow25^{\circ}C$, both with 50% R.H., covering the upper body (U) or lower body (L) with garments. 1. When the upper or lower body is covered or exposured respectively, the mean skin tempterature of upper body is higher than that of lower body. And upper body is more easily influenced by the environmental temperature than lower body. It means the skin temperatures of the upper body change faster than those of the lower body following the environmental changes. 2. In U and L, the skin temperatures of the upper limbs (thighs, upper arms) are lower than those of the peripherals (hands, feet). 3. Warm sensations and skin temperatures of the upper body showed high correlation and it was the case with cold sensations and skin temperatures of the lower body. 4. In high temperature condition $(25^{\circ}C\rightarrow35^{\circ}C\rightarrow25^{\circ}C)$, mean skill temperature and rectal temperature in L were lower than in U. This lower rectal temperature in L is probably due to the insulation of the lower body with garments that promotes the heat radiation only in the high temperature environment.

The results are as follows. 1. Oriental medical terms which express abnormal sensations are Bulin, Mamok, Mamokbulin. 2. Bulin, Oriental medical terminology, was used from Naegyeong's era to the Song Dynasty era and expressed as one of the symptoms in Jungpung(Stroke), Bi syndrome(Obstruction syndrom of Gi and Hyeol), Wi syndrome(Flaccid paralysis of the limbs), Hyeolbi(One of the Bi syndroms). But since the Keum Dynasty era, Mamok or Mamokbulin were more used than Bulin and that was refered as seperated disease. 3. Ma is paresthesia or dysthesia on the skin and the limbs, and the symtoms are not itchy, patients are felt like insect's crawling or bite. Mok is a stubborn symptom , the patients are felt like tree, which don't know pain and itching sensation. And therefore Ma is similar to positive phenomena and Mok is similar to negative phenomena in clinical aspect. 4. Mamok is GiHyeol(Gi is functional activities, Hyeol is blood) and Gyeonglak(Meridian system)'s disease. It's main causes are Giheo(Deficiency of Gi) and Hyeolhel(dificiency of Blood) and inducing tactors are Pung-Han-Seub(pathogenic wind-cold-dump) and Damtak(Phlegm-turbity), Eohyeol(Stagnated blood). 5. Mamok is induced from mononeuritis, multiple mononeuritis, polyneuropathy in the peripheral nervous lesions and also induced from cervical spondylosis, spinal tumour, multiple sclerosis, cerebrospinal vascular disease in central nervous systems.

A good school uniform leads students to good behavior and have them enjoy desirable school life. Therefore a better fabric for girls' high school uniform suggested through two series of studies; first, examined the various aspects of current uniforms. Second, made a new fabric for uniform considering elasticity for activity and comfortableness, and compared its characteristics with those of the current uniforms. The results are as follows; 1 Most of students wanted uniforms considering elasticity for activity and wearing. 2. The measurement of the elasticities of the uniform materials showed that the material which was made using the elastic material was more elastic than the currently used material by 42.12% in summer material and 20.05% in winter one. 3. The analysis using the combination of the values of mechanical properties showed that the elastic material was better in the wearing, tactile senses, and drape properties than the current material, even though it was a little worse in shape-stability. 4. To compare the thermal insulation, clo values were measured. For winter uniform, the elastic material was better than the current one in keeping warm. However, This study did not find any big difference between summer uniform materials.

Fashion films with screen limits have a way of changing communication methods through sensorial organs in order to go beyond limits. This study shows that such change is possible if fashion films are based on haptic factors. This study examines haptic factors of fashion films from the three perspectives of filming factors of different shot size, synesthetic, and cinematic screen methods. First, when the subject to be emphasized is enlarging, the observer comes to project themselves to the situation and incurs a haptic sensation. Second, when associating an experience by personal recollection or social customs when more than two senses are stimulated simultaneously, haptic sensations, triggered by multiple senses, takes place. Third, a blurred image shows haptic sensations through inducing observers to see into the meaning of a shot. As a result, the senses of the observer enlarge and enhance a communication ability through absorbing and accepting a fashion film. Furthermore, fashion films are effective in understanding the cultural forms of the age.

This study investigated EEG signal, subjective fragrance sensation, and the preference of differently colored cotton knit treated with Citrus unshiu oil containing microcapsules as well as examined their relationships for providing regression models on subjective fragrance preference. Color variables combining 2-level hue (Yellow and Green) and 3-level tone (strong, pale, and grayish) were applied by dyeing prior to microcapsule treatment. We invited 28 female college students aged 20's for EEG signal experiments and subjective fragrance sensations with fragrant knit by rubbing. EEG signals at $mid-{\alpha}$, $fast-{\alpha}$, and $low-{\beta}$ showed significant differences depending on color; Green had more relative power values and grayish tone did more at $low-{\beta}$. Even though subjective sensation showed no significant differences depending on color, some of them such as Fresh, Comfort, and Natural showed significant correlations with EEG signal at $low-{\beta}$, which means that the fragrance sensations of Citrus unshiu fragrance are concerned with attention and alertness for Koreans. Fragrance preference was regressed significantly using some EEG signals and subjective sensation. The results could be utilized to value up fragrant textiles by Citrus unshiu oil.

The purpose of this study was to investigate the effect of body fat on energy metabolic response and subjective sensations under the hot environment. Fifteen female university students volunteered as subjects. We organized subjects into three groups: low body fat group(group L : less than 20% of body fat), medium body fat group(group M : 20%~30% of body fat) and high body fat group(group H: more than 30% of body fat). The experiment was conducted with $32^{\circ}C$, 60%RH. The subjects repeated 'Exercise' and 'Rest' period. The results of this study are as follows ; The oxygen uptake value of AM is higher than PM. The value of group H is the highest in three fat groups. But it showed group L is the highest in oxygen uptake per weight. %body fat is the lower, oxygen uptake is the higher. In Calorie, group L has higher value in AM in than in PM. In M group and group H, a value of PM is higher than AM. In group H, difference of AM and PM is the highest. From a view point of three groups, a value of group H is the highest. This support that calorie increases as oxygen uptake increase. The heart rate values of group L and group H are the higher in AM than in PM. This support that heart rate was relation to oxygen uptake. In all three groups, the value of blood pressure is higher in AM than in PM. Subjective sensations of temperature sensation, thermal comfort, and wetness sensation are higher in Am than in Pm. This explains that subject sensations are similar to experimental data, such as oxygen uptake, heart rate, blood pressure. In oxygen uptake, heart rate and blood pressure, general tend to showed higher AM than PM. This showed that heart rate, oxygen uptake increase in AM, as blood pressure increase, too. From a view point of %body fat, group H is higher than the others in oxygen uptake, heart rate and blood pressure.
