본 연구는 스스로 선택하고 결정하는데 어려움이 있는 지적장애인을 위한 직업s훈련 프로그램 중 하나인 한지공예가 그들의 직업적응능력에 어떠한 영향을 미치는지를 알아보는데 그 목적을 두고 시행되었다. 한지공예 훈련이 지적장애인의 직업적응능력에 미치는 영향을 직업인성검사(Work Personality Profile: WPP)의 5가지 하위 영역으로 나누어 어떻게 변화가 나타나는지에 대해 분석하였는데, 직업인성프로파일(WPP)은 장애인의 직업적응능력을 알아보기 위하여 미국 아칸소 주립대학의 Roessler와 Bolton이 1985년에 개발한 도구이다. 한지공예가 지적장애인의 직업적응능력에 미치는 효과를 알아보기 위한 실험설계의 독립변인은 한지공예 프로그램(8작품)이고, 종속변인은 직업인성프로파일의 하위 요소 5가지(독립적 수행 가능, 집단 내 작업수행, 권위에 반응하는 능력, 동료와 적절한 상호관계, 작업 에티켓 규칙이해)이다. 한지공예의 효과를 검증하기 위하여 한지공예 훈련 프로그램 8작품을 사전검사, 중간검사, 사후검사로 변화를 분석하였다. 연구 결과 나타난 영역별 평균직업인성프로파일 변화를 살펴보면, 직업적응능력 5가지 영역 모두에서 사전검사(평균 64.8)보다는 중간검사 점수 (평균 75.1)가 높게 나왔고, 중간검사보다는 사후검사 점수 (평균 88.7)가 높게 나타나 프로그램의 효과를 확인할 수 있었고, 마지막으로 연구결과가 의미하는 함의를 제시하였다. This study is to find out the effect of the Korean traditional paper craft program for the people with intellectual disabilities on their abilities to adapt to their works using a more definite series of programs that may satisfy the needs by intervening in their vocational rehabilitation processes in consideration of their performance-related characteristics having difficulties in choosing and deciding something for themselves. For this purpose, this study is going to be made about the abilities of the people with intellectual disabilities to adapt to their works, including the ones to perform works independently, perform works within a group, respond to authority, have appropriate relationships with co-workers and understand the work-related etiquette rules. A research question is what effect dose the Korean traditional paper craft have on their abilities to perform works independently, to perform works within a group, to respond to authority, to have appropriate relationships with co-workers, and to understand the work-related etiquette rules? For this purpose, this study was made against 5 people with intellectual disabilities, who were participating in the work adjustment training in sheltered workshop of the Community Center for the Disabled in Gwangju City. The test was carried out from Sept. 1, 2009 to April 30, 2010, 64 times for 32 weeks, twice every week, 90 minutes in each session. In measuring the variations of the abilities to adapt to works, the Work Personality Profile (WPP) was used. The Work Personality Profile consisting of 58 items might be called a comprehensive and behavior-oriented work assessment instrument that scores the results of the analysis of the contents based on 11 reasonable transfer criteria and 5 factor criteria. The followings are the results of this study. Before intervening in the Korean traditional paper craft program, a pre-test was performed against the test group. After having implemented the program, an intermediate check was made against the test group to which the program had been applied. The post-test was performed after intervening in the Korean traditional paper craft program. As a result, the Korean traditional paper craft program had a positive effect on their abilities to perform works independently, to perform works within a group, to respond to authority, to have appropriate relationships with co-workers, and to understand the work-related etiquette rules.

This paper presents the application of integrated mathematical programming approach for the design of cellular manufacturing. The proposed approach is carried out in two phases: The first phase concerning exceptional elements(EEs) in cell formation and the second phase facilities layout design. This paper considers the total costs of three important costs for (1) intercellular transfer (2) machine duplication and (3) subcontracting. One of important issue is the calculation of the number of machines considering the maximum utilization of machines and the available capacity of a machines that can be transferred between cells. Facilities layout design is considered to reflect the real field data taking in to account the operational sequence of the parts to be manufactured. The model is formulated as mixed integer programming that is employed to find the optimal solution.

Changes in manufacturing system are those that occur during production and cause the systems to behave unpredictably. So scheduling problem in this dynamic industrial environments is very complex. The main concept of this dissertation is to continuously monitor a manufacturing system status(Rate of Prior Job, Rate of Large Job, Rate of Shortest due date Job, Job Interval Time) and detect or predict a change so that scheduling system will react by modifying production schedule(dispaching rule) to lessen the effects of this change.

Applications of the plate heat exchanger are being expanded in ships and marine plants. Marine engine L.O(lubricant oil) cooler is one of the applications of the plate heat exchanger. It has very important role as engine radiator in the ship. Lubricant oil is flowed inside ship engine like the land engine and temperature is up to 80~90℃. Some L.O coolers are mounted in the front of the engine, and operating pressure is up to 4~8 ㎏/㎠. Because vibration of engine is passed to L.O cooler, anti-vibration is required. New L.O cooler for medium speed marine engine was developed, and its performance was evaluated by test and provided in this paper.

We investigated the sintering behavior and piezoelectric properties of lead-free $(K_{0.5}Na_{0.5})NbO_3$ ceramics co-doped with excess 0.01 mol ZnO and x mol $MnO_2$, where x was varied from 0 to 0.03. Excess $MnO_2$ addition was found to retard the grain growth and densification during sintering. However, 0.005 mol $MnO_2$ addition improved the piezoelectric properties of 0.01 mol ZnO added $(K_{0.5}Na_{0.5})NbO_3$ ceramics. The planar mode piezoelectric coupling coefficient, electromechanical quality factor, and piezoelectric constant $d_{33}$ of 0.01 mol ZnO and 0.005 mol $MnO_2$ added specimen were 0.40, 304, and 214 pC/N, respectively.
