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.

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.
