The purpose of this paper is to present a new strategic framework of Supply Chain Management(SCM) in the automobile industry. For our purpose, we first had studied about the structure of relationship between supplier and buyer in Korean automobile industry. With this study, we searched for factors which compose a strategy of SCM, and whether or not the companies" performance that are influenced by specific SCM strategy factors. Of course, our study based on existing researches, especially Cox et al.(1995) and Venkatraman et al. (1992), but the existing researches is differentiated in this paper that is treated several power factors as resource, value, environment and relation. So, results of our paper are what a good strategy of SCM composed by these factors and how to adopt this strategy on global logistics. And our methodology has some using of statistics method by SPSS 14(v) such as factor analysis, reliability analysis, and SEM(Structural Equation Model) with AMOS.

The paper describes the prediction method for the unsteady flow field and the aeroacoustic noise of an small axial fan. The prediction method is comprised of various CFD conditions and acoustic analogy by using Ffowcs Williams-Hawkings equation. The tested fan was an axial fan with impeller outside diameter 170 mm and 5 blades. Virtual anechoic room which has same size with real one was used for CFD. URANS and LES turbulence models were used and optimized mesh was selected with mesh dependence study. Calculation conditions were also studied such as time step and sampling time of noise analysis. In this paper, we got optimum analysis conditions and computational results, their results were compared with measured ones.
