The purposes of this study was to examine the college students'value and the status of their clothing purchasing behavior, and to compare the correlation between both of them. The questions were centered on 511 students who are attending the universities in Seoul. The results of this study were as follows. First, most students have higher value on politics, economy, and theory in the order listed. Male-students were interested in theory, while female-students were more interested in politics. Second, when they purchase their clothes, the factor of decision was based on design and their observation was another important factor. As for selecting shops, they considered the product as the most important factor and then the service & transportation. Third, I inspected the correlation between their value & the status of their clothing purchasing behavior. The students with lower theoretical value considered the quality as a purchasing factor, and the service as a purchasing factor, common shop as a purchasing shop, adn the convenient transportation system as a factor of selecting a shop.

In order to clarify the enhanced sintering behavior of nanostructured(NS) W-Cu powder prepared by mechaincal alloying, the sintering behavior during heating stage was analysed by a dilatometry with various heating rates. The sintering of NS W-Cu powders was characterized by the densification of two stages, having two peaks in shrinkage rate curves. The temperature at which the first peak appear was much lower than Cu melting point, and dependent on heating rate. On the basis of the shrinkage rate curves and the microstructural observation, the coupling effect of nanocrystalline W-grain growth and the liquid-like behavior of Cu phase was suggested as a possible mechanism for the enhanced sintering of NS W-Cu powder in the state.

This experimental study investigates the hysterestic behavior of traditional timber frames subjected to lateral loads. Prototype frames for this study were selected from one of typical national treasures for timber structures in Korea. For simplicity roof structures and braket systems were excluded from specimens and the joint behavior of beam-to-column system were presumed to have crucial effect on their global behavior. The experimental observation showed stiffness degradation and slip after experiencing initial yield and the first cycle at a new larger displacement due to inherent gaps in traditional timber connection and gradual indentation of interfaces, The cyclic behaviors of all specimens were similar to those os modern timber frames with bolt and nail connections. Additional structural members such as an upper beam and clay-filled wall increased the initial stiffness strength and energy dissipation. It is expected that collapse of Korean traditional timber frames under lateral load is mainly caused from P-$\Delta$ effects rather than local member failure.
