Cost and Benefit Analysis for Safety Management Cost by FMEA/HAZOP at Governor Station
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 1~9
Cost-benefit analysis was investigated to propose the analysis method of the effect of investment and the optimum investment level of safety management cost for preventing gas accident in the B governor station. From five classifications of safety management costs consisting of cost items with similar characters and potential accident costs calculated by risk assessments(FMEA/HAZOP), we found that the order of the benefit(the reduction cost of the potential accident cost) was the instrument increase and repair cost > the safety checking and inspection cost > the labor and training cost > the safety equipment and corresponding cost > the research and development cost. As the benefit was increased with increasing the investment cost, the effect of investment was increased with decreasing the Investment cost. As a result, the optimum safety management cost was estimated and the investment level was analyzed by the model of optimum investment level.
A Study on Policy Execution Analysis of Industrial Safety Health Criteria

We have endured a lot of social and economic loss due to the industrial calamities. A study for the government policies to reduce the loss in the field of industrial safety and health leaves much to be desired. The practical one on the government policies industrial safety and health policies, however, hasn't been accomplished as much expected. The purpose of this study is to suggest a research framework fir the execution process analysis, which is needed to find out the desirable or undesirable elements of industrial safety and health policies. The focus of the analysis lays on a policy problem of the industrial safety and health criteria. And based on this paper, it will proceed to the practical research for the industrial safety and health policies.
Adaptation to the product liability of systematic approach to accident scenario analysis (SASA)
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 19~34
Since the introduction of product liability law from America in 1960s, product liability has been on the rise as an important problem to the quality management of company and consumer's safety. Together with this, before the legislation of product liability system in Korea, the sense and level of company and consumer about product safety are rapidly changing, In times like the present, ensuring more systematic product safety and consumer safety, and the buildup need of competitive power in accordance with product liability prevention of company grows raising. Therefore, this study presents the most effectively manageable ways of product liability the side of safety management of consumers and companies through the ensuring ways and activity models of product safety and certification system in company.
A Case Study on Developing the Virtual Safety Training System
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 35~44
In the real environment, it is very limited for the trainees to participate the effective training using actual training equipments by themselves and also to simulate several hazard situations for safety because of the direct exposure to the hazards of the actual system. But the virtual environment(VE) can help the trainees to get the effective training participating by themselves and to simulate all kind of possible situation without the exposure to the hazards of the actual system. In this paper, the new developed VE system for safety training is introduced. The system is more effective and economic one than the other system developed in Japan.
A Study on Phenomena of Watertree and Dielectric Breakdown in XLPE
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 45~52

Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 53~63
The individual rotten water purification tank recently discharges wastewater and sewage through the outlet without purification ability. The outlet water and affiliated water purification tank with microorganism cultivator tank cultivates microorganism and then drops the value BOD, COD of sewage and discharges the quality of water into the outlet. The blower and water pump operating continuously prompts the waste of energy and deterioration of equipment. Each room of deposition tank, foaming tank, microorganism cultivator tank is equipment with the sludge detection senses so it can detect the density of each room. The power-drive plant of the blower and water pump which are the system cultivating the microorganism must be made as fuzzy controlization (If the sludge amount of each room become higher, the rate of operation of blower and water pump must heighten, on the contrary, in case of row sludge amount, the total handling amount and microorganism handling amount of each room of control. Tank reducing the rate of operation must be DB. At present, the blower amount in proportion to the sludge and oxyzen demanding amount has to control. Each room mus be checked outlet level of the outlet, also each room must flow backward discharge materials, and must operate feed-back control until we want to be come as a below value of BOD/COD(10PPM ; KS).
A Note on Theoretical Development ＆ Applications in Reliability Analysis using Field Data
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 65~76
Field data have been recorded as the time to failure or the number of failure of systems. We consider the time to failure and covariate variables in some pre-specified follow-up or warranty period. This paper aims to investigate study on the reliability estimation when some additional field data can be collected within-warranty period or after-warranty period. A various likelihood-based methods are outlined and examined for exponential or Weibull distribution.
Study of Attitude towards CTD
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 77~90
This paper summarized the results of previous and recent studies on cumulative trauma disorders (CTD) and provides a prevention strategy for CTD and showed the results from a quite extensive survey with tables and figures. This is a follow-up study of Kwon (1993) 〔2〕. From the previous studies, Kwon (1993) showed that many people are exposed on CTD, but they did not only know the clear reasons why they got CTD, but also how to prevent or change their workstation〔2〕. Lee (1996) showed the result from both field survey and medical examination. He found that most frequent symptoms are CTS (nerve disorders) and tendon disorders 〔6〕. From these previous results, it is obvious that CTD patients will increase in Korean industries if we did not pay attention to this CTD problem. Therefore a proper education of Ergonomics, CTD prevention for workers and moderate changes in workplace are necessary. From 1998 and 1999 follow-up studies, there are still many people(23％) did not hear about CTD, CTS, or MSD. Only 42％ of respondents is exercising during or after work for short-time. Therefore, there are many rooms for prevention strategy of CTD and education for preventing CTD.

Development of Maintenance Sequence System by Using Modified FMEA and CBR
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 103~112
In Factory, as the number of machine is increased the more maintenance efforts are necessary. Multi maintenance issues may occur at a certain time and the determination of maintenance sequence is needed. In this study, we first compare the priority of machines and the impact value using modified FMEA(Failure Mode Effect and Analysis) method. Also, CBR(Case-based Reasoning) approach is applied to retrieve similar fault cases of current machine problem. The proposed methodology will be useful to implement decision support system of maintenance sequence for CMMS/EAM (Computerized Maintenance Management System/Enterprise Asset Management).
A study on the relationship between layoff and shareholders' wealth
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 113~122
This study is to examine the effect of layoff on shareholders' wealth. Firms make layoff decisions by reason of cost cutting, lower performance, demand decline, restructuring. Therefore, I think that stock market responds to layoff positively, since the firm's labor productivity and profitability is improved after execution of layoff, I find that layoff variables effect on abnormal return positively in regression analysis. This means that layoff sends positive signal to the stock market for the firm's future performance. Therefore, layoff has a good effect on shareholders' wealth.
A Study on eCRM Operation of Apparel Industry Using Axiom Design
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 123~133
With ever-change and increasingly competitive business environments, firms strive to employ a variety of marketing strategies and execution in order to survive in the market. Such effects would be paid off in the right way only when management of the firms perform marketing activities focusing on long term effectiveness, which would drive company profits up and keep them for long. Demands of customers are being changed and varied. And in this circumstance, it become a main issue of management that the company should produce and sell products according to the customer demands. With these trends, each company has been concentrating effects on generalization of product development technique and distinction of service for customer. In this result with the advantage of mass marketing and database marketing have been drawing attentions from company. Also the internet connected around the world completely diminished the limit of time and distance and company have enveloped keen competition out of each nation and continent in the world market. To fulfill these demands of customer, they need a concept of eCRM(Web based Customer Relationship Management), and go from selling products and services, or gathering customer requests, up to the phase of solving customer's problem by real time or previous action. With the help of internet, the frequency and speed of the problem solving has improved greatly.
A Study on the Economics Evaluation using Weighted Average Cost of Capital
Journal of the Korea Safety Management and Science, volume 3, issue 4, 2001, Pages 135~144
The capital cost of the company is one that must be paid to the money owner as the price by using the money. The capital cost according to the source of money supply can be estimated by the expected profit rate undertaken by the use of the capital. But in the area of pre-existent economic evaluation, the evaluation of the company investment has been treated by the profit rate of the capital after considering the repayment conditions of the other's money or the interest. Thus in this study, in case the company makes an investment on various kinds of the capital at the same time, not make use of the capital as a one source, the economic evaluation of an investment should be handled by taking the weighted average cost of capital into consideration in proportion to the constitution of the capital cost by the sources of money supply, Especially, as the cost of the private money is very much connected with the profit rate through the stock market, the Capital Asset Pricing Model (CAPM) will be applied. This kind of economic evaluation method can be said to have much to do with the Economic Value Added : EVA) as well as to be highly thought as a standard to estimate the company' value recently To certify the usefulness of this approach, the case study of the output of the capital cost will be made for the purse of the economic evaluation of the alternative investment by using the financial statements of a motor company H.
