Religion affects all the dimension of human beings, and at the same time it forms one dimension of human beings. Costume Is considered as a result that reflects the phases of the time and the characteristics of a wearer. Costume, also, has been influenced by religion that has led one's belief, social spirit and culture for a long period of time. The Eastern aesthetics has expanded the area of thoughts with the concepts that originated from Buddhism, Taoism, and Confucianism. Among the concepts, Non-Dualistic Theory is the core idea of Buddhism.'rho theory contains the moaning that one should not lean to one side between existence and nonexistence and should not be obsessed with the center. It was the most powerful Buddhistic idea that had an influence on Asian aesthetics. Korean traditional costume is not an exception. This study has a significance that it was conducted to understand the relation between religious principle and traditional custom through mainly using documentary records. The formative characteristics of Korean traditional costume influenced by Non-Dualistic Theory ran be summarized as non-structure like, indeterminate forms, amorphousness and anti-decoration such as plainness, temperance and achromatic color. Aesthetic value was expressed through 'the aesthetic of emptiness', 'the aesthetic of hiding', and 'the aesthetic of nature'. Although the appearance of a religious symbol can change, an essential element in religion lasts as human society remains. Although our clothing culture has converted to western style, Korean traditional aesthetics is placed deep inside of 'the Koreans' spirit and has a consistent effect on our overall culture of clothing.

The equitable partitioning problem(EPP) is classified as [0/1] binary skill existence or nonexistence and integer skill levels such as [1,2,3,4,5]. There is well-known a polynomial-time optimal solution finding algorithm for binary skill EPP. On the other hand, tabu search a kind of metaheuristic has apply to integer skill level EPP is due to unknown polynomial-time algorithm for it and this problem is NP-hard. This paper suggests heuristic greedy algorithm with polynomial-time to find the optimal solution for integer skill level EPP. This algorithm descending sorts of skill level frequency for each field and decides the lower bound(LB) that more than the number of group, packing for each group bins first, than the students with less than LB allocates to each bin additionally. As a result of experimental data, this algorithm shows performance improvement than the result of tabu search.

This study investigates the effects of the material properties and the fatigue behaviors in the SM490A material butt weld specimens due to the heat-treatment and the grinding. In the fatigue behavior, the heat-treatment affects the fatigue life. The S-N curves of both matrix specimen and butt weld specimen are reversed at some cycle by the existence or nonexistence of heat-treatment. The grinding on the bead makes the fatigue limit decrease in the all specimens. But the reinforcement removed, the fatigue limit increases at the high cycle. Also, this study investigates the fatigue life estimation by examining butt weld bead profiles. The butt weld beads, which are welded by semi-robot method, have non-uniform bead profiles described by $\theta,\;\rho$ and h. The stress concentration factors $K_t$, are changed by each different $\theta,\;\rho$ and h from 1.395 to 2.863. Hence, the sensitivity of $K_t$ is changed by each $\theta,\;\rho$ and h. As $\theta$ becomes lower and $\rho$ and h become higher, $K_t$ increases. The fatigue life can he estimated very closely for the AAY specimens without residual stress using only butt weld bead profiles. But, fur the AAN specimens with residual stress, the fatigue life must be estimated by considering both the weld bead profiles and the residual stress data.

This study, through the cases occurred in mathematics pencil-paper test, after analyzing the types and the factors of misunderstanding, was to seek to pursue the alternatives to diminish the misunderstanding caused in paper test. When classifying misunderstanding shown in pencil-paper test, four types are found - unsuitable edit, unsuitable organization, formal/typical habits, and unsuitable question situation. One Way, considering accomplishment rate based on existence and nonexistence of misunderstanding factors, the testing paper, that is, type A with misunderstanding factors, showed that the accomplishment rate is 10 percent below the testing paper, type B excluding misunderstanding factors. Also, after distinguishing only items including misunderstanding factors, in comparison with the accomplishment rate, the results showed about 22% difference. And in the type of misunderstanding factor, when system was unsuitable, the degree of misunderstanding appeared seriously. The more complicated many types were, the higher the number of misunderstanding cases appeared. Based on these study results, the conclusions are the followings : First, teachers should try to develop examination papers for exact evaluation. Second, teachers, while students are solving the questions, misunderstanding recognize what are the misunderstanding factors they feel. Third, in the pencil-paper evaluation, the work that teachers should consider importantly, is to analyze students' thought process. Fourth, teachers should try for smooth communications with students.

This papers describes on the experimental consideration for the intrinsically-safe explosion-proof capability of rechargeable battery's body about main item rechargeable battery and cellular phone battery which is selling in domestic that IEC(International Electrotechnical Commission) recommend the measurement of ignition limit by short circuit of rechargeable battery and temperature increase test to use a explosion grade Group IIC type of explosion-proof type apparatus test an object of hydrogen gas. Because of that there are many different results for existence or nonexistence for ignition by different company and different types. It is concluded that the maximum of self temperature increasing by spark circuit of rechargeable battery is $180^{\circ}C$ in case of Nickel-Hydrogen and $110^{\circ}C$ in case of Nickel-Cadmium. The reaction of cellular battery for external temperature have following processes. It is confirmed that the temperature of reaction is rise slantly as the ambient temperature rising, then exterior shape of one is swell up and change when the temperature of ambient reach to about $130\~140^{\circ}C$, and when reach to about $160^{\circ}C$ the battery is blown up. Therefore, it is considered that have to be in considering selection of rechargeable battery using in itself due to different ignition limits of various rechargeable battery when the portable electric containing rechargeable battery are designed, produced and used, the characteristics and the proper safety factors of devices.
