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.

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.

Knowledge integration is becoming a primary function of improving organizational capabilities and performance in today`s convergence paradigm. The knowledge integration capability of employees has increasingly been regarded as a critical source for developing new products and services. This study investigates the influential factors of employees` knowledge integration capability and its effects. A theoretical research model was developed based on the socio-technical perspective and information processing theory. The model includes teamwork quality, expertise, IT support, and knowledge complexity as the primary influential factors of employees` knowledge integration capability. A large-scale survey was conducted for gathering data (a total of 316 samples from 141 organizations) to test the proposed model. The test results of the hypotheses show that expertise and knowledge complexity are the significant influential factors of employees` knowledge integration capability, and also the capability has a positive effect on the knowledge creation performance of employees. Our findings contribute to the development of initiatives for promoting employees` knowledge integration capability, especially in knowledge intensive organizations focusing on convergence products and services.

The purpose of this study is to provide some basic data which will help to guide the Pre-school children`s Sports Program, while suggesting some good directions which may develop such activities, based on the motive and satisfaction of some childrens, researched in this study, who are participating in the sport-activities of the Re-school children`s Sports Program of the children-sports-specializing agency, after having generally investigated and reviewed the operation of the baby-sports-specializing agency. In order to achieve it, in the first place, two hypotheses were set as follows: First, the motive of participating in YWCA`s Pre-school children s Sports Program will differ according to the area where children`s participate in the group s sport activities, the points the children`s parents emphasize or prefer, and the period how long they participate in such activities. Second, the satisfaction in participating in YWCA`s Re-school children`s Sports Program will differ according to the area where children`s participate in the group`s sport activities and the period how long they participate in such activities. In order to find out answers for the set hypotheses, 5 branches belonged to Seoul YWCA in 2002 were set as a matrix group ; investigation started from September 2 to September 28,2002; some necessary data were collected by means of some questionnaire; and so, total 322 sets of questionnaire were collected; then only 300 sets of questionnaires were used for necessary data since other 22 sets were improper. From the data, actually the answers to questioning item, the factors of satisfaction were analytically studied; and the degree of reliance appeared as a=.875-.560. Data process was done by Cross Analysis and One-way ANOVA. Scheffe Method was used for the `after the fact` test. And the significant level of all the statistical values was set as a=0.5. In the result of this study, regarding the motive of participating in YWCA`s Pre-school children`s Sports Program; first, according to the area where childrens participate in the group`s sport activities, their motive significantly differed; second, according to the points the children s parents emphasize or prefer, their motive significantly differed; and according to the period how long they Participate in such activities, their motive did not significantly differ. And regarding the satisfaction in participating in YWCA`s Pre-school children`s Sports Program group; first, according to the area where childrens participate in the group`s sport activities, their satisfaction significantly differed in terms of facilities, sport leader or guider, and program; and according to the period how long they participate in such activities, their satisfaction did not significantly differ.
