This study aimed to search for the fundamental accident causes using a categorical analysis, a kind of statistical methods. As the analysis methods, correlation analysis, independence test and logistic regression analysis were used. And the SPSS package, a general-purpose mathematical library, was used to obtain statistical characteristics. As the result of this study, the accident causes associated with factor of 'lost working days' were factors such as 'employed periods', 'sex', 'type of accident', 'month'. In case of applying independence test method, the most important cause was the factor of 'month'. In case that logistic regression analysis method was applied, the cause contributed to the increase structure'. 'less than 6 month'. On the basis of these results, the plan for accident prevention and the proper investment for accident prevention expenditure could be carried out in each workshop.

This research modified the checklist used in the universities in USA, England and Korea considering the current situation of Korea, and conducted case studies upon each section of appointed chemical laboratories based on 4M criteria, which stands for Machine, Media, Man and Management. The purpose of the studies is to assess how dangerous the laboratories are and to contribute to prevention of accidentsin the laboratories as well as reducing loss of lives and property. The result of this research found out the harmful and hazardous factors based on the 4M-type checklist and predicted the dangerousness as it multiplies possible frequency by intensity. Protective equipment, safety facilities in laboratories, emergency exit and compressed gas cylinder are found to be more dangerous, so the result shows that it is desirable to improve ventilation, safety facilities and circumstances of the laboratory through the investment.

How to maintain the optimal electric power generation mix is one of the important problems in electric power industry. The objective of this study is to develop a computer model which can be used to forecast the investment in power generation unit by the plant owners after restructuring of electric power industry. Restructuring of electric power industry will make difference in decision making process of investment in power generation unit. After Privatiazation of Power Industry, Gencos will think that profit is the most important factor among all others attracting the investment in the industry. Coal power generation is better than LNG CCGT in terms of profit. However, many studies show that LNG CCGT will be main electric power generation source because the rest of factors other than profit in LNG CCGT are superior than Coal power generation. The impacts of the various government policies can be analyzed using the computer model, thus the government can formulate effective policies for achieving the desired electric power generation mix.

Many developed countries, including Korea, are rapidly aged owing to years of use. Infrastructures such as roads, water, and sewage are Social Overhead Capital (SOC), which provide convenience to the nation and support national economic growth. Thus, continuous maintenance and investment are required because infrastructure deterioration is directly related to social effects, such as quality of life and safety. In addition, because infrastructure maintenance costs a lot of the budget, it is necessary to appropriate criteria for budget allocation, given assessing the condition of infrastructure. This study developed an Infrastructure Maintenance Map (IMM) based on a Geographic Information System (GIS) for infrastructure maintenance budgets and investment priorities. The IMM uses maintenance information for roads, bridges, water, and sewage, obtained from Bridge Management System (BMS), Pavement Management System (PMS) and facility data in South Korea. The IMM can calculate deterioration levels and maintenance costs of infrastructure repair methods. Maintenance priorities are also evaluated based on Multi-Attribute Utility Theory using the deterioration level, economic feasibility, and effect of facilities. This study contributes to easy decision-making regarding infrastructure investment priorities and maintenance budgeting to the status of facility on the 3D map by IMM.

The industrial accidents in the construction business have decreased on the basis of the accreditation of KOSHA 18001, one of the occupational health and safety management system. However, the interest and investment into the KOSHA 18001 has grown down because of the worsened construction business so that the construction companies that maintain the system as a mere formality has begun to be displayed. In this regard, this study performed the interview with the internal and external review board as well as the question investigation from the persons concerned in order to apprehend the current problems in the KOSHA 18001. First of all, the internal reviewers in the KOSHA are lack in the comparison with the number of new and renew accreditation. Secondly, many persons concerned with the KOSHA has required the quantitative criteria for the accreditation. Consequently, the manpower supplement associated with the external reviewers, the grading evaluation would be strong solutions to improve the effectiveness of KOSHA 18001.

Korea was followed by a rapid increase in road construction investment in late 1980s with the help of strong economic conditions. As a result of such investment, it will be expected that there must be a rapid increase in demand for maintenance or rehabilitation of the facilities after 2010. We are developing asset management information systems for enhancing user's satisfaction and innovating the facility management techniques within a limited budget. We suggested the assessment items for the Level of Service for tunnel facility's operation and maintenance(O&M), in this study. We have surveyed for the importance of assessment items by considering both user's viewpoints and facility management agency's viewpoints. We came to realize the relative importance of the items based on this survey using the Analytic Hierarchy Process(AHP) method proposed by Satty. The relative importance of assessment items in terms of the user's viewpoint was identified in descending order such as safety, mobility, accessibility, convenience, O&M efficiency, comfort, rural revitalization, environment, and information. Also, the importance of the items in terms of the management agency's viewpoint was identified in descending order such as safety, mobility, accessibility, environment, rural revitalization, convenience, O&M efficiency, information, and comfort. It means that safety of tunnel facilities is more important than mobility, although which is the basic function of the road facility, both in agency's and user's concern. Therefore, the agencies have to pay more attentions and efforts to ensure safety of tunnel facilities when they establish the investment plans for the tunnel facility O&M.

As a result of investment in railway safety since 2004, railway accidents have been reduced by half and we reached a high level of safety compared to other countries. But people are still worries about railway accident, and want safer railway. It is difficult to determine which level of safety must be achieved due to lack of comparative studies on railway safety among different countries and other transportation modes. In this study, a comparative study on railway accident statistics and various transportation modes is performed. The results of this research can be used for the determination of weak areas of railway safety and the level of safety to be achieved.
