The subjects in this research were 368 girls in high school for survey, and wearing sensation and physiological responses were investigated through wearing trials on human body in climatic chamber based on these results from the survey. The results are as follows : 1. They enjoyed wearing t-shirts, jackets, vests, and blouses in order for the upper clothes, and they preferred t-shirts to blouses. For the lower clothes, they enjoyed slacks much more than skirts. The weight of clothes was significantly heavier in the group where they wore the uniforms(U-group) than in the group where they wore the free styles(F-group). When they chose the school wear, activity was the most important of all, and the maintenance was the least. 2. As the classes were a little cool and dry, most of them dissatisfied the environment. The degree of the satisfaction of the class environment and properties to it were higher in the U-group than in F-group. 3. In the textiles, colors, styles, activity, static electricity, seasonal property, and easiness of putting on and taking off the clothes, F-group was more satisfied than U-group. U-group was more satisfied than F-group in the soil of the clothes. 4. The thermal comfort, thickness, and tightness of the clothes were not significantly different between the groups. The clothes of U-group was heavier than those of F-group, and the tactile sensation in U-group was worse than F-group. In U-group the students felt the skirts very inconvenient when they acted. 5. The weight of the clothes influenced the wearing sensation, therefore the heavier the clothes were the less satisfied they felt. 6. The inside temperature of clothes was significantly higher in U-group than in F-group. The skin temperatures of abdomen and arm were significantly higher in U-group than in F-group, while the skin temperatures of thighs and legs were significantly lower in U-group than in F-group. U-group felt heavier than F-group in wearing the clothes. Therefore the improvement of the clothes weight is needed.

The building envelope is important specially for saving energy consumption of residential buildings. but Apartment houses in Korea commonly have inside insulation system which have constantly arisen thermal bridges, the risk of heat loss, as a necessity. This study aims to evaluate integrated insulation performance according to the different shapes of external walls, adjacent to windows. The thermal performance analysis was carried out by Equivalent U-value and using the three-dimensional heat transfer computer simulation (TRISCO-RADCON), under nine different cases of comparing among three each of different bases(current standard model, 30percent energy saving model and 60percent energy saving model). The heating and the cooling load were also compared between two cases (standard U-value and Equivalent U-value) of three each of different bases, using the Building energy simulation which is based on DOE-2.1 analysis. As results, it turns out that if the Equivalent U-value is considered on the envelope analysis, the heat flow loss will be increasing more than the standard U-value, and if heat insulation property of the residential building reinforced rather than current, the rate of influences on the thermal bridges would be extremely expanded. In addition, it is shown that annual heating loads of the apartment house with applied Equivalent U-value substantially increased by more than 15 percent compared to those with the existing U-value, but annual cooling loads were negligibly affected.

The protection of Design is very important issues in these days. Even though Interior Design is also one of important design sections, it is relatively unprotected by formal intellectual property laws, yet creativity and innovation flourish. The needs for protection of Interior Design have been creased. The aim of this study is to suggest the weakness of the system for protection of Interior Design. The proposed research is comprised of two themes. One is to research Acts related to protection of Interior Design. The second is to study the registered cases under the Design Protection Acts. These two theme is generated by the comparative review between ROK and U.S.A. Through these comparative results, this study propose some considerations for an effective protection for Interior Design. Design need to be registered in the hole image of the space not a partial element. The concept needs to be protected because it is more effective way to respond the copying. Exterior for facade and Interior Design need to be registered in one registration to use the protection system actively.

The degree of the photodoping process in Ag(100[.angs.])/a-Se$_{75}$Ge$_{25}$(1500[.angs.]) films has measured as a function of the photon energy between 1.5[eV] and 2.9[eV] with the exposing time. The "window" characteristics of Ag occur at 3400[.angs.] (3.65[eV]) and Ag is almost transparent in this region. It is shown that transmittance is almost constant (40-50%) for the wavelength ranges of our experiment. It is found that the energy gap of a unexposed a-Se$_{75}$Ge$_{25}$ film is 1.81[eV]. Ag photodoping process results in the photodarkening effect which the absorption edge shifts to the long wavelength. Especially, very large band shift (-0.3[eV]) is obtained by exposing He-Ne laser(6328[.angs.]).. We have obtained "the U-type property" for Ar He-Ne and semiconductor laser. It is associated with the variation of energy gap(E$_{g}$) with photo-dose and substantially is explained by DWP model.l.gap(E$_{g}$) with photo-dose and substantially is explained by DWP model.

Based on 11 Classics of Materia Medica designated by Ministry of health and welfare bulletin 1995-15 as legal basis in scope and preparation of herbal prescription, we reviewed indication, property and processing of Rhus Verniciflua Stokes which appear extensively in literature since earlier Joseon Dynasty. Following is the conclusion of this review after comparing with 'Korean Pharmacopoeia: commentary on herbal product standard'. 1. The properties of Rhus Verniciflua Stokes in 'Korean Pharmacopoeia :commentary on herbal product standard' should be changed as 'Tonifying the middle, restoring the muscle, fulfilling marrow, breaking old static blood, tonifying and activating after removing mass, unblocking the meridian, killing worms' and indication should be changed as 'Old static blood, deep rooted mass, wind-cold-dampness arthralgia, cough, 9 types of chest pain, abdominal or flank accumulation of stagnated qi[氣], amenorrhea, hernia mass, small bowel or bladder colic pain, abdominal pain due to worm accumulation'. 2. The processing of Rhus Verniciflua Stokes in 'Korean Pharmacopoeia: commentary on herbal product standard' should include 'natural drying or steaming drying followed by grinding and stir-baking until ripened or smoking appears'.

In this paper, we analyzed the performance for CATV/LAN added priority problem. Upstrea nm channel which analyzed very deeply for CATV/LAN network have the preferential access property depending upon that positionand unidirectional property. To solve that fairness problem and priority, we propose the CSMA-CD/U/P-P protocolthat transmit as P1 probability if data packets happen. We assumed 2-Class priority(high, low). As the analyticresult and simulation, we obtained P1, value and its average delay time under priority problem assumed twoscenarios. Also, we get its variance value and queue length. Especially, the mean delay time increases nearer thanposition from H/E
