This paper determines the allocation of computers and data files to minimize the sum of processing and communication costs which occur in processing jobs at each node. The problem of optimally configuring a distributed computer system belongs to the class of NP-Complete problems and the object function of this paper is nonlinear function and is hard to solve. This paper seeks the solution of distributed processing system by Tabu Search. Firstly, it presents the method of generating the starting solution proper to the distributed processing system. Secondly, it develops the method of searching neighborhood solutions. Finally, it determines the Tabu restriction appropriate to the distributed processing system. According to the experimental results, this algorithm solves a sized problems in reasonable time and is effective in the convergence of the solution. The algorithm developed in this paper is also applicable to the general allocation problems of the distributed processing system.

Au/Ni coatings are widely used in the electrical interconnect system, such as connectors, sockets and wire crimps. But due to repeated mechanical contacts, fretting corrosion occurs and causes a rapid increase in resistance. As an attempt to resolve these problem, application of Ni-P-PTFE to replace Ni undercoats was proposed, for which basic materials properties of Ni-P-PTFE coatings for preventing fretting corrosion was examined in this study. The Ni-P-PTFE coatings were formed by electroless Ni plating and PTFE coating followed by the heat-treatment. PTFE particles were found to be uniformly distributed in the Ni-P matrix. The Ni-P-PTFE coatings showed the excellent anti-adherent property with the contact angle of $104.3^{\circ}$, microhardness of 144.3 Hv comparable to that of Ni-P, and electric conductivity equivalent to that of Ni-P.

As operating period of older vintage nuclear power plants increases, many multiple cracks have been found in steam generator tubes made of Alloy600MA, thus a robust predictive model for either burst pressure or coalescence pressure of these multiple cracks in steam generator tubes is highly required. Nothing that steam generator tubes are typically failed by plastic collapse, the crack alignment and combination rules considering this material characteristic of steam generator tubes should be suggested. The objective of this paper is to predict the plastic collapse pressures of non-aligned dual cracks and to propose coalescence criterion based on detailed 3-dimensional (3D) elastic-plastic finite element (FE) analyses. The geometric variables of non-aligned multiple crack in steam generator tubes affecting burst or coalescence pressure, i.e. circumferential and longitudinal distances between two cracks and crack length of each crack, are systematically varied. Using the present FE results, the crack interaction effect of non-aligned multiple cracks are assessed and new alignment and combination criteria of non-aligned multiple cracks of steam generator tubes are also proposed.

The purpose of this study was to analyze the effect among university students leisure participation motivation and physical self-concept. The data were collected from 439 university students in Seoul participating in leisure activity. Frequence analysis, exploratory factor analysis, Cronbach`s α, correlation analysis were used using SPSS 15.0 version for window statistics package. The findings of the study were as follows: First, there were statistically significant differences among sex and grade groups in regard of leisure participation motivation. Second, there were statistically significant differences between sex groups in regard of physical self-concept. Third, physical self-concept factor(sport competence, appearance, fitness) were affected by leisure participation motivation. There were differences among men students and women students of leisure participation motivation. Finally, if it were the more participation of leisure participation motivation, the higher point of physical self-concept.
