  • The objective of this study is to develop accident scenario models for the risk assessment of railway casualty accidents. To develop these scenario models, hazardous events and hazardous factors were identified by gathering various accident reports and information. Then, the accident scenario models were built up. Each accident scenario model consists of an occurrence scenario model and a progress scenario model. The occurrence scenario refers to the occurrence process of the event before the hazardous event. The progress scenario means the progress process of the event after the hazardous event. To manage a large amount of accident/incident data and scenarios, a railway accident analysis information system was developed using railway accident scenario models. To test the feasibility of the developed scenario models, more than 800 domestic railway casualty accidents that occurred in 2004 and 2005 were investigated and quantitative and qualitative analyses were performed using the developed information system.

  • Unlike in general manufacturing process, safety management in laboratory-based research area is complicated because the latter generally involves trying untested methods or handling unusual substances in small amounts. Laboratory accidents in South Korea have recently shown an increasing trend. Unfortunately, statistics on such accidents are not officially published by any domestic public agencies. In this study, multivariate analysis was performed on the relationships between variables to develop effective strategies for preventing laboratory accidents. A Cross-Tabulation Analysis of accident-related factors in 179 accident cases revealed that the laboratory type, accident type, and unsafe-act type are all statistically significant, whereas the unsafe condition and management factors differ with the statistical criteria. Furthermore, the results of a Multiple-Correspondence Analysis showed that accidents can be divided largely into three groups having different accident causes and injury types; this confirms the necessity of different strategies to prevent accidents of each type. The findings also reveal differences between the distribution of accident types mentioned in the accident case collection books and actual reported cases. This suggests that an official statistical system administered by a public institution would be necessary for effective prevention of laboratory accidents.

  • Since the unprecedented hydrogen fluoride leak accident in 2012, there has been growing demand for customized technical information for rapid response and chemical accident management agencies including the Ministry of Environment, the National Emergency Management Agency, and the National Police Agency need more information on chemicals and accident management. In this regard, this study aims to provide reliable technical data and guidelines to initial response agencies, similar to accident management technical reports of the US and Canada. In this study, we conducted a questionnaire survey and interviews on initial response agencies like fire stations, police stations, and local governments to identify new information items for appropriate initial response and improvements of current guidelines. We also collected and reviewed the Canada's TIPS, US EPA's hydrogen fluoride documents, domestic and foreign literature on applicability tests of control chemicals, and interview data, and then produced items to be listed in the technical guidelines. In addition, to establish database of on-site technical information, we carried out applicability tests for accident control data including ① emergency shut down devide, safety guard, shut down valve, ground connection, dyke, transfer pipe, scrubber, and sensor; ② literature and field survey on distribution type and transportation/storage characteristics (container identification, valve, ground connection, etc.); ③ classification and identification of storage/transportation facilities and emergency management methodslike leak prevention, chemicals control, and cutoff or bypass of rain drainage; ④ domestic/foreign analysis methods and environmental standards including portable detection methods, test standards, and exposure limits; and ⑤ comparison/evaluation of neutralization efficiency of control chemicals on toxic substances.

  • It is a fact that domestic performance art has been sharply progressed but it is focused on only performance quality technique, not on safety of performers and the audience. It is a pity that people's effort to keep safe stage environment have not traced to innovative change, eventually leading to be forced to perform under hazardous condition. This study is to find out and identify that domestic regulation and accident cases are investigated and compared with cases of advanced countries, to verify that performer and the audience are main elements to develop performance art. And it is to show more effective safety measure after pointing out hazardous elements. Research change is limited to review only performance ones of all cultural facilities and to review accident cases from these places to show reasonable safety measures for stage facilities. Operation manager covers almost all of areas such as devices, management, despite a fact that they take charge of stage facilities, illumination, sounds, already. Some conclusions are as follows; 1) performance theatre-related regulations should be established again. domestic safety standards for performance theatre safety should be established. 2) characteristic and purpose of performance place should be clarified at the stage planning and design of them 3) operation expert performance place is required to be trained to cover emergency situation at any time.

  • Domestic industry calamity rate did decrease in large numbers by many efforts of the safety and health organizations. But that is low yet among the OECD countries. Calamities are started In most work inexperience and safety consciousness absence. So, we can know that education is how important. Domestic small and medium enterprises are in trend that industrial accident is increased by deterioration of hardware, not enough preparedness of safety equipments. But, the safety and health education had not been utilized so far effectively and applied systematically. Therefore, the most important among many means to reduce calamity is the safety and health education. An efficient education will supply suitable knowledge and technology to work people. And that will lead to prevent accident by building right habit and attitude. This research did the survey about problems of education that is enforced in small and medium enterprises. That survey is done to three groups of workers, administrators and managers. We compared domestic safety and health education system and advanced foreign system. And, analyzed problems and presented a solution. Finally, this research presented efficient operation model of the safety and health education suitable to domestic medium and small enterprises.

  • The safety should be primarily considered for air vehicle, such as helicopter, which is not easy to cope with when out of order or loss of control that followed catastrophe. The U.S National Transportation Safety Board (NTSB) investigated and analyzed for 34 years rotorcraft accidents that occurred from 1963 through 1997. This paper handles intensively the relative investigation and analysis of recent 10 years domestic civil helicopter accidents to those of the United States in order to increase the safety of helicopter transportation and to consider the main design parameter before we develop Korean Civil Helicopter. To understand the overview of civil turbine helicopter accident, it uses the NTSB's accident investigation results and the overall accident trend for U.S civil single and twin turbine engine helicopter according to category, cause, activity, and phase of operation.

  • Domestic insurance claims were statistically investigated to analyze the elderly driver's accident patterns and injury types in side impact crashes. Medical treatment records and accident vehicle damage photos have been surveyed for 5,419 cases. The results of our statistical analysis showed that the thorax injury risk of the elderly drive group is 8.8 and 4.0 times higher than that of the young and middle age group respectively. Diagnosis showed that most thorax injuries were caused by rib fracture. The head injury risk of the elderly female driver group seemed to be higher than that of the younger female driver group, however, statistical test has not been conducted because of the lack of number of samples for elderly female accident.

  • Although the national radiological emergency response system has been improved by incorporating lessons from the Fukushima nuclear power plant accident and recent domestic natural disasters, it has not fully incorporated these lessons. In addition, it cannot deal with a variety of aftermath of the radiological disaster. Even for the same disaster, the national emergency response system should comply with multiple domestic laws in our country. Furthermore, there are a few discrepancies between the articles of the domestic laws that the national radiological emergency response system should address. Therefore, this study investigates the characteristics of radiological disasters, examines articles on the domestic laws related to the national radiological emergency response system, and analyses the Japanese government's responses to the Fukushima nuclear power plant accident. Based on the results of the review, suggestions for the improvement of the national radiological emergency response system in terms of response organization and framework have been proposed in this study.
