Stress at work as well as at home is one of the most important issues in the health sector. However, very little research has been to find the relationship between the levels of stress and exercise. In this study, we used a structured questionaires received from 15th June to 29th October 2002 in order to prove the relation between the degree of exercise and stress. A total number of 1,092( 569 male, 523 female) who have worked more than one year were investigated. The results of the study were as follows： (1) The mean levels of stress were lower in the regualr exercise group than in the non-exercise group； (2) The more time spent in exercise, the lower level of stress was shown； (3) It was shown that the association between the frequency of stress was inversely realted to the frequency of exercise in males whereas the levels of stress was lowest in those who exercised less than 2 times per week in females； (4) The levels of stress was lowest in those who exercised more than 1 hour at a time. In summarizing the result of this study, the degree of exercise is realted with stress regardless of gender. Consequently, it is expected that regular and consistent exercise would be an important tools in lowering and protecting the worker's stress.

Educational facilities have an affect to make a decently learning environment. After constructed, it needs a maintenance plan to keep the performance or function which provide the repair time, repair scope and ratio. But the fundamental data are so insufficient that the field worker can't provide the maintenance plan and has no choice use the other data which concerned with apartment or office building. Above all, the service life is indispensible to make a repair plan because the repair time and scope would be provided within the service life. This study aimed at providing the method to make a service life of component in educational facilities and applying the method into the roof proof and floor finishing. Results are shown that first, it is important to set the $1^{st}$ repair time after constructed. when it proposes the three ways with the probability approach, choice probability model and cumulative cost function. Second, the service life of roof proof is provided with about 35 years. In addition, the service life of the floor finishing is about 40 years. These result would be utilized to conduct the repair plan under the service life.

Cutting process has been automated due to progress of CNC and CAD/CAM, but polishing process has been only depended on experiential knowledge of expert. Polishing work for a curved surface die demands simple and repetitive operations but requires much time for its high precision. Therefore it is operated in the handiwork by skilled worker. However the workers intend to avoid gradually polishing work because of the poor environments such as dust and noise. In order to reduce the polishing time and solve the problem of shortage of skilled workers, it has been done some research for an automation of polishing. To automate the polishing process, a 2 axes polishing robot which is attached to a 3 axes machining center has been developed by our previous research. This automatic polishing robot is able to keep the polishing tool normal on the curved surface of die. Therefore its performance of polishing is improved because of always keeping the tool normal on the surface. In this paper, the smaller sized polishing robot is developed to improve polishing performance. And the controller for 2 axes polishing robot is developed. The controller is composed of TMS320C31 with high speed which is 40-ns instruction cycle time, RAM memory with 64K words, digital input with 64 bits, digital output with 32 bits, and D/A converter with 4 channels, which is 12 bits resolution. To evaluate polishing performance of this developed robot, polishing experiment for shadow mask was carried out.

부산신항의 환적화물 처리물량은 지속적으로 늘어나 전체 물동량의 50%를 넘기고 있지만 작업자의 경험에 의존한 작업의 순서 결정에 따라 효율적인 환적화물 운송이 이루어지고 있다고 보기 힘들다. 특히, 외부 트럭이 필요한 경우가 많은 타부두 환적은 작업 상황에 따라 차량 대기로 인한 과도한 혼잡으로 물류비 증가와 사회적 비용이 발생하게 된다. 이 문제를 해결하기 위한 방법 중 하나는 트럭의 단일 운송을 최소화하고 작업을 마친 트럭을 다른 작업에 투입하여 활용하는 듀얼 사이클 운송을 최대화하는 것이다. 이에 따라, 본 연구에서는 컨테이너 터미널간 환적화물의 듀얼 사이클 운송을 위한 방안에 대해 연구하고자 한다.
