The purposes of this study were 1) to verify the theoretical model of the influential factors of brand variety seeking tendency in clothing products by identifying the relationships among optimum stimulation level, fashion leadership, fashion innovativeness, brand variety seeking attitudes and brand variety seeking behavior and 2) to identify the relationships among research variables according to clothing items(suits, jeans, casual jackets, T-shirts, panties, stocking) and the level of clothing involvement. The data was collected from 457 female college students living in Seoul and suburban areas, and was analyzed by frequency, one-way ANOVA, SNK test, multiple regression and path analyses. The results of this study were as follows: 1) There were significant effects of optimum stimulation level and fashion leadership on fashion innovativeness, significant effects of optimum stimulation level, fashion leadership and fashion innovativeness on brand variety seeking attitudes, and significant effects of brand variety seeking attitudes on brand variety seeking behavior 2) There were significant relationships among the research variables in case of suits and jeans. The relationships between variables were differed according to clothing items and the level of clothing involvement.

In this paper, we introduce a Y/T(Yard Tractor) Multi-Cycle System on the basis of RTLS that improves a low efficient loading and unloading. In the proposed approach, we apply the best suited algorithm looking for seeking of the optimum path and the shortest movement distance. In this paper, Our experiment results show that rate of a driving distance is reduced more than 12% compared to the average value, and that is reduced more than 23% compared to the maximum value.

A container terminal productivity is maximized by a minimized time for processing containers. So, we have been elevated the container terminal productivity through an improvement of computing system, but there are a limitation because of problems for transportation management and method. A Y/T(Yard Tractor), which is a representative transportation, is able to do only one process, loading or unloading, at one time. So if the Y/T can do loading and unloading step by step at a same time, the processing time would be shortened. In this paper, we proposed an effective operating process of Y/T(Yard Tractor) Multi-Cycle System by applying RTLS(Real Time Location System) to Y/T(Yard Tractor) in order to improve the process of loading and unloading at the container terminal. For this, we described Multi-Cycle System. This system consists of a real time location of Y/T based on RTLS, an indicating of Y/T location in real time with GIS technology, and an algorithm(Dijkstra's algorithm) of the shortest distance. And we used the system in container terminal process and could improve the container terminal productivity. As the result of simulation for the proposed system in this paper, we could verify that 9% of driving distance was reduced compared with the existing rate and 19% of driving distance was reduced compared with the maximum rate. Consequently, we could find out the container performance is maximized.
