우리나라의 해양안전심판원은 지난 40년동안 많은 업적을 남겼지만, 아직도 해양사고의 조사에 대한 법과 제도 및 매뉴얼 등의 내용 면에서 미흡한 점이 있다. 조사매뉴얼은 국제해사기구의 해양사고조사지침 등의 국제규정과 기준을 수용하지 못하고 심판지침과 함께 작성되어 있을 뿐만아니라 그 구성과 내용 및 조사기법 등이 매우 부실하다. 그리고, 조사제도는 심판원이 독립성을 가지지 못하고 재발방지를 위한 권고기능이 크게 위축되어 있는 실정이다. 또한, 해양사고의 원인판단지침이 없어 조사관이 항법을 적용하는데 있어 혼동하거나 오류를 범하는 경우가 종종 발생하고 있고 초임 조사관 등의 사고원인판단의 기준으로 활용할 수 있는 교재도 없다. 이 연구에서는 영국, 미국, 네덜란드 및 일본의 조사매뉴얼과 조사제도를 비교ㆍ분석하여 개선안을 제안하고, 사고 종류별 질문조사기법을 제안한다.

The number of car accident is Recently on the increase in Korea because of the explosive increase of cars, the poor road condition, the lack of safety facility, and others. The insurant with a accident has to decide whether receiving a insurance or not. In this paper, we represent a reasonable decision support material by calculating the approximate insurance fee based on the discount rate and premium additive rate, which is changed by the accident type and the accident expenditure. Practically, there is difference in the standard insurance rate and premium additive rate according to the accident type and the accident expenditure in Korea. The premium additive rate is assessed considering the number of accident, the pattern of accident, and the reason of accident for 3 years. In this paper, we represent a decision making method considering not only the first-time car accident but also the future car accident. For considering the repeated accident, we analyzed the real data accumulated until the year of 1996 from S Insurance Company, and estimated the probability density function between the first and the second-time accident, and executed the goodness of fit test using ARENA and STATISTICA software. Using this conditional PDF, we can calculate the insurance fee next 3 years and compare the insurance fee with the equivalent present value of cash flows. The program performing this analysis is represented, and written in VISUAL BASIC Language. We tried to suggest an accurate guideline for the insurant to decide the insurance coverage rationally, and tried to correct a wrong idea of dependence on the car insurance only by the amount of the accident expenditure. And we expect this study can generally be applied to many different accident types under the uncertain circumstances in our daily life.

Objective: The purpose of this study is to draw the accident prevention model using the signal detection theory, and to implement accident prevention program, based on a health promotion and support activities in a shipbuilding company. Background: Workers' health management is perceived important from the human resource management perspective, as well as from the personal perspective. Method: This study developed an accident prevention model by analyzing the correlation between 704 workers' health examination variables, and reviewed the verification of the model through a follow-up survey on the control variables and status of hazards targeting 650 workers for four years from 2007 to 2010. Also, a health promotion program was implemented targeting a production division to improve alcohol habits, smoking, musculoskeletal pain complaints and hearing control indices, which are the control variables of the model. Results: As a result of four years' implementation, the following effects were obtained: the days away from work fell 87.5%, and accident rate dropped 71.5% in 2010, respectively, compared to 2006, before the activity was implemented. Conclusion: This study shows that the accident prevention activities based on workers' health promotion activities are effective to prevent industrial accidents and injuries. Application: The research findings will serve as a practical guideline for establishing preventive measures in the shipbuilding company.

Objective: The purposes of this study are to survey needs for changing accident investigation from blaming to systems approach and to briefly summarize systems-based accident analysis techniques. Background: In modern complex socio-technical systems, accidents are caused by a variety of contributing factors including human, technical, organizational, social factors, not by just a single violation or error of a specific actor, but accidents investigation used to be focused on the incorrect action of individuals. A new approach investigating causes of accidents as a symptom of a deficient system is required. Method: This study was mainly based on survey of literatures related to accidents, accidents investigation, which included academic journals, newspapers, etc. Results: This study showed that accidents investigation of Korea focusing on blaming is problematic. This was confirmed by two concepts of migration and hindsight bias frequently found in accident causation studies, and an attribute of accidents having varying causes. This was illustrated with an example of Sewol ferry capsizing accident. Representative systems-based accident analysis models including Swiss cheese model, AcciMap, HFACS, FRAM and STAMP were briefly introduced, which can be used in systematic accidents investigations. Finally, this study proposed a procedure for establishing preventive measures of accidents, which was composed of two steps: public inquiry and devising preventive measures. Conclusion: A new approach considering how safety-critical components such as technical and social elements, and their interactions lead to accidents is needed for preventing reoccurrence of similar accidents in complex socio-technical systems. Application: The results would be used as a reference or guideline when the safety relevant governmental organizations investigate accidents.

The study on industrial accidents in Korea has been focused on frequencies of each type, severity, characteristics, causes, and so on. Those attributes of industrial accidents were usually analyzed independently, so that it was hard to provide a systematic guidelines for efficient safety management. Therefore, there were a few of studies based on comprehensive survey results in terms of characteristics of safety management. This study aimed to figure out the characteristics of current safety management and to provide a guideline for ideal safety management in industry. The questionnaire survey carried out for the workers(695) who were in charge of safety management at their industries. The multivariate analyses as well as descriptive statistical analysis were conducted. The factor analysis showed that there were three factors of safety management. They were 1) investment and management for accident prevention, 2) safety manager, and 3) general health and environmental condition. The industries of respondents were clustered into three groups. Three groups showed a statistically significant differences on the number of cases reported and the trends of accident. Actually, the group with the larger investment and better management of accident prevention had a smaller number of accident cases.

Recently, the government is pursuing to reduce the serious accidents in most industries, including the construction industry, by enacting laws on punishment. The accident rate tends to be depended on the size and type of construction sites, and the accidents occur frequently due to inadequate implementation of safety management system and management standards, especially, in small and medium-sized sites. This study has performed the profiling of 265,000 accident cases on construction sites by attribute analysis such as the ratio of days lost to work, and pattern of days lost to work compared to the size of the construction. It turned out that the proportion of accident cases was high mainly in small-scale construction sites, and long-term labor losses occurred. Shortly, it is necessary to establish an institutional standard for applying a realistic safety management cost calculation and management system centered on small-scale sites. Therefore, this study is expected to be used as fundamental data or guideline for developing a customized safety management and accident prevention system for a worker reflecting the conditions of a construction site in the future.

Objective: This study aims to survey and compare three systemic accident investigation techniques of Accimap, STAMP and FRAM, based on the application studies of the Sewol ferry accident. Background: Traditional accident investigation methods such as domino models, FTA, etc. work well for losses caused by physical component failures or actions of human in relatively simple systems, but are unable to depict mechanisms generating errors and violations in the current complex socio-technical systems. For better understanding the structure and behavior of the socio-technical systems, systemic techniques have been developed and used. Method: This study was mainly based on survey of literatures through surfing webpages of ScienceDirect and Google, and ergonomics relevant journals. The key words of Sewol, Sewol ferry, Sewol ferry accident, etc. were used in the survey. Results: Three systemic accident investigation methods included similar actors in the Sewol ferry accident including government, Ministry of Ocean and Fisheries, Korean Coast Guard, Korean Register of Shipping, Korea Shipping Association, Chonghaejin Marine Company, crew members. The methods graphically represented each level's failures or performance variabilities of relevant functions and relationships between them. It was shown that the systemic methods consider the entire system, ranging from the environment in which the accident occurred, to the role of government in shaping the system of work. Each method has its own comparative pros and cons, but the Accimap has advantages in terms of time of analysis, data required, model complexity and degree of comprehensiveness. Conclusion: This study reviewed and compared three systemic accident investigation methods, which showed that there are systemic characteristics and pros and cons in the methods. Application: The results would be used as a guideline when selecting accident investigation methods.

이 연구는 고속도로에서 발생한 교통사고에 대한 기하구조의 영향을 알아보고자 시도되었다. 기하구조의 경우에는 지침 등에서 정하는 기준 권장값등이 있지만, 기존의 사고모형에서는 교통사고에 영향을 미치는 기하구조의 자료가 통합된 형태로 사용되어 혼합된 형태로 설치된 현실을 추정된 모형이 제대로 설명하지 못하는 단점이 있다. 따라서 이 연구에서는 기하구조를 기준값에 의해 세분화된 기하구조 자료를 사용함으로써, 현실을 반영한 모형을 추출하고자 하였다. 그리고 각 기하구조별 탄력성 분석을 통해 사고에 미치는 영향을 제시하였다. 이는 향후 교통안전을 고려한 기하구조의 지침 정립에 도움이 될 것으로 사료된다.
