Occupational illness analyses are used to identify common factors contributing to occupational illness and to give recommendations for illness prevention. We discuss safety and health management policies based on the present status of MSDS(Musculoskeletal Disorders) characteristics and the actual safety and health problems. These results can be used to develop more effective occupational safety and health management policies for the prevention of MSDS.

The aim of this thesis is to evaluate visual art policy during Kookmin government period(1998-2002). In the beginning, many artists had expected president Kim Dae Jung to enlarge arts support But the evaluation of them was very negative vecause the government was only interested in the development of cultural industry. First, I analysed the government expenditure in the visual arts. Department of Culture and Tourism took the responsiblity of visual arts policy. The budget of art and culture increased to 1% of total government expenditure in this period. But the main factor was the increasement of cultural industry and tourism expenditure. The budget of visual arts in 2002 was only 6,600million won. Second, I analysed visual arts support programs. (1) The government introduced studio programs for the first time. For 5 years, 2 mational studios and 23 public studios were established. (2) The number of art museum was increased to 62. (3) It introduced alternative space supported 200million won annually. (4) percent for art scheme reduced from 1% to 0.7% of total construction cost, but still 27 public sculpture gardens were built. (5) Business support for visual arts reduced because of IMF. (6) Also arts marker froze and many commercial galleries were closed. (7) In order to revitalize region through arts and to promote international exchange of culture, Gwangju Biennale was created. Third, I analysed Arts Plan 2002. It had a radical Limitaion because it was established in the last year of Kookmin government period. Also it showed special favors to some arts organizations. In general, I think that positive outcomes are the introductions of the studio program and the alternative space support program. Especially alternative space support program enforced the diversity of visual arts, and encouraged creative young artists. But policy of art market failed because of IMF and visual artists had to go through rough times.

As part of a hierarchical production control system, a policy is proposed for the admittance for new parts to a flexible manufacturing system (FMS) together with two different heuristics for dynamic routing of parts. The heuristics that consider the process plan's flexibility with respect to machines and operations are based upon operating time and machine reliability. To quantify flexibility, it is developed a priority type of the measurement considering machine's reliability that incorporates all the job and machine characteristics that contribute to routing flexibility. HUR which considers machine reliability is applied to drive some simulated systems and compared with the HUS using SPT rule. It is found that HUR outperforms HUS using SPT in terms of makespan and machine utilization.

A probation system of death penalty can lie halfway between death penalty and life sentence. Since grotesque and crude murder cases continually happen in Korea, it is difficult to abolish death penalty right now. We need to introduce the probation system of death penalty, which may be regarded as an interim stage for abolishment of death penalty. I have investigated the current death penalty system in China and found the following problems: There are many kinds of crimes punishable by death penalty, the appropriate condition is not shown to apply the probation system of death penalty, and the number of execution is the largest in the world. However, the probation system of death penalty has the following advantages: It is a humanistic system to head for the return to society, a positive effect of correction can be anticipated during the probation, and danger of misjudgement can be minimized. Moreover, in regard to the probation system of death penalty, I have explored a range of probation judgement, the probation period, the screening procedures of application, and the cases of remission.
