The purposes of this study were to find out an evaluation scale that could predict wear comfort and to investigate the effect of the skin-contacting fiber type on the subjective sensation and microclimate. Sensorial evaluation was basically followed by the Human Perception Analysis (HPA) interviewing 144 consumers. Sixteen female subjects were participated in the sleeve wear test with and without wearing vapor permeable water repellent outerwear. Experimental sleeves were constructed using the same double knit by turning inside out to control other material effects except the skin-contacting fiber type, hence each different side of double knit, cotton side and the cotton/polypropylene blend side, was next to skin in each trial of the experiment. As results, it was noted that the term representing a combined feeling of thermal and wetness sensation, and muggy appeared to be a powerful language to measure perceptual responses of human subject among five dimensions of evaluation. although the ordinary users did not use the term very often. As for the comfort properties of double knits, it seemed that subjects slightly more preferred polypropylene/cotton blend to cotton as the skin-contacting fiber type when they wore outerwear and their skin were covered with sweat, although the result was rot statistically significant and need to be confirmed under higher work load.

This study was conducted to verify the advantages of Gal-Ot. Gal-Ot is defined the clothings dyed with persimmon juice. Firstly the physical properties of fabrics were examined. Secondly the wear tests were conducted. The wear tests were performed in climatic chamber controlled 3$0^{\circ}C$ air temperature 50$\pm$5% R.H and 0.2m/s air movement. Four women subjects participated in this experiment and 4 times experiments were performed per one subject. The expeimental schedule was planned following 4 steps that is sedentary posture during 30 minutes-walking the 5。slope treadmill by 70m/min during 20 minutes-sedentary posture during 20 minutes-standing posture on toward the blowing wind during 10 minutes. The results obtained is as folows : The insulation of fabric was increased with dyeing with persimmon juice. The air permeability of fabric was remarkably increased with dyeing with persimmon juice. The mean skin temperatures of subjects were apt to be higher in wearing Gal-Ot than undyed clothing. The clothing micro temperature of subjects were slightly inclined to become lower in wearing Gal-Ot than undyed clothing, The clothing micro humidity was decreasee when: the subjects were gal-Ot than wore undyed clothing, And then it brought about more comfortable on wear sensation. The differences of physiological reactions were not consistent between clothing types except for sweat rate on the back. This result may be attributed the to complex experimental schdules consisted of four steps and to a little difference between open type and close type. However I consider that the clothing type of Gal-Ot is suitable for open type because Gal-Ot is summer wear for blocking the sultry heat.

Adjusting pressure level in the construction of athletes' tight-fitting garments by reducing the elastic knit pattern is a challenging subject, which influences the performance of the wearer directly. Therefore, in this study, relationship between the reduction rates of the basic pattern obtained from 3D human scan data and resultant clothing pressure was explored to improve the fit and pressure exerted by clothing. 3D scan data were obtained using Cyberware and they were transformed into a flat pattern using software based on Runge-Kutta method. Reduction rate was examined by subjective wear test as well as objective pressure measurement. As a result, difference in the length between the original 3D body scan data and the 2D tight-fitting pattern was 0.02$\sim$0.50cm (0.05$\sim$1.06%), which was within the range of tolerable limits in making clothes. Among the five garments, the 3T-pattern was superior in terms of subjective sensation and fit. The pressure of the 3T pattern was 2$\sim$4 gf/cm2 at five locations on the body, which is almost the same or a bit higher than that of Z-pattern. In the case of tight-fitting overall garment, the reduction rate of the pattern in the wale direction is more critical to the subjective sensation than the course direction. It is recommended that the reduction grading rules of course direction should be larger than that of Ziegert for a better fit of tight-fitting garments. In the case of wale direction, however, reduction grading rule should be kept the same as suggested earlier by Ziegert (1988).

As an effort to maximize the immersiveness of user experience in virtual reality, there have been constant efforts to provide a user with tactile sensation by providing haptic feedback. Most of the haptic feedback methods, however, can create only limited or unrealistic haptic sensations since they utilize affordable actuators such as a vibrotactile actuator. When it comes to martial arts training or a game, the limitation of such haptic feedback is apparent due to the significant difference between the physical impact of hitting an object and the sensation departed from a vibrotactile actuator. Noting this, we proposed a haptic impact system that can create a haptic impact when the user hits a virtual object with the fist. The haptic interface uses a quick-return mechanism that can deliver haptic impact feedback to a user's fist. The realism of the haptic impact was evaluated by conducting a human-subject experiment. The results indicate a significant effect of haptic feedback on the realism of the virtual impact.

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.

Objective : The purpose of this study was to investigate the effects of sensory diet home program for children with autism spectrum disorder who have sensory defensiveness and explore how this intervention affect to sensory modulation and social interaction ability. Methods : The subject of this case study was a 12-year-old girl with autism spectrum disorder who was struggling with her sensory modulation problem. Parent interview and evaluations were conducted and subject-tailored sensory diet home program was made by the therapist. Parent education for the home program was provided to parents and everyday, 3 times, 30minutes of home program activities were conducted to the child for 23 days. Adolescent/Adult Sensory Profile and Social Maturity Scale were measured at pre and post intervention and parent wrote daily observation record about child during the intervention. Results : After the intervention, Low Registration, Sensory Sensitivity, Sensation Avoiding area of Adolescent/Adult Sensory Profile included to the normal range and the scores of the Social Maturity Scale improved. Conclusions : Child's sensory defensiveness was relieved and sensory modulation and controling emotion ability were improved. While there was significant improvement for sensory modulation and social interaction ability, this was a case study and there was only one subject. So we need to study with larger sample size to generalize this intervention's effectiveness.

This study was peformed to characterize the physiological signal prior to develop an algorithm which quantifies EEGs evoked by tactile stimulation. The experiment was devised with four experimental conditions, which were control and two levels of pressures in tactile sensation. Twenty subjects were used to obtain EEGs while applying tactile stimulation using two types of textiles, soft towel and sand paper, to the right hand of each subject. EEGs were acquired for 20 seconds, and each trial was repeated five times randomly at the different levels of stimulus intensities. The index, $S_{n}$, was obtained by calculating the ratio of energy distribution in the time-frequency plot for each scored psychological state of the subject. The results showed that dominant aspects of the EEG signals have their maximal frequencies concentrated at a lower ranges for the resting and pleasant state, while the spectral energies were distributed to higher frequency ranges when subjects experience an unpleasant emotion.

This study investigated the formation of communication education which is based on the contemporary language education. Concretely I watched chronologically the proportion of culture element and behavior element, its change, and the contents of writing education. To achieve this, I took the ancient Greek language education as the main materials. The sophists are right if we think only the empirical world, because of the changeability of external world and the relativity of sense. On the other hand, Platon emphasized the ability of abstract thought which is inherent in the human inside. But today's education only emphasizes the 'expression' which came from the Platonic thought. So students fills their devastated inside with arbitrary idea in this history-forgotten social circumstance. It is very beneficial to make subject have some cultural studies and to enhance the sensation on the world through the writing of representation because these can be good to the growth of subject. It is our-not as educator but as a predecessor of human being-duty to set the catalogue of cultural studies of this age and to make students feel the fundamental harmony and the beauty of the world.

Peripheral neuropathy is a disease of multiple Peripheral nerves. Tingling, pins-and needles, numbness, burning and raw sensation are symptoms of peripheral neuropathy. These symptoms are frequently complained by patients who suffered from obstructive syndrome of Ki and blood (痺證). This case was reported to evaluate the effects of oriental medicine therapy on a patient with obstructive syndrome of Ki and blood (痺證). The subject was a female patient who had obstructive syndrome of Ki and blood (痺證). She complained of calf pain, cold sense, walking discomfort, insomnia, dyspepsia, anorexia etc. We administered the medicine with dispeling the cold pathogenic factor (寒邪), adjusting the constructive and defensive energy (調營衛), tonifying the Ki and blood (補氣血) by stage. After the treatment, the symptoms improved. This case suggests that oriental medicine therapy can be applicable to improve in symptoms with Peripheral neuropathy.

Now days, as the consideration of sound environment is getting important, method of physical measurement such as reverberation time and sound pressure level becomes common. However, such method cant include subjective sensation such as personal emotion and feeling, evaluation. So there is a limitation to make the most optimized sound environment. Therefore, in the present experiment, I improve big indoor gymnasium that has sound defect because of too long reverberation time. After that, I conduct the auditory sense evaluation of human psychological response. From the experiment, I will make research into sound satisfaction rate about the subject space and response of each item. As well as, I will present the result as basic database of sound environment improvement experiment of indoor gymnasium.
