교통사고 발생위험예보의 목적은 교통사고를 저감하기 위한 것이다. 따라서 본 연구는 조건에 따른 교통사고발생 확률을 산정하여 효과적인 교통사고 위험 예보를 목적으로 하였다. 국내에서는 인터넷 등을 통해 사망사고 정보를 포함한 교통사고의 통계수준의 정보를 제공하고 있으며 최근에는 날씨에 따른 광역지자체 단위의 지역별 주간 교통사고 위험도수준 정도의 정보를 개략적으로 제공하고 있다. 그러나 모든 운전자에게 동일내용의 정보를 제공하는 것은 개인의 특성과 환경을 반영하지 못한 것으로 한계가 있다. 그러므로 본 연구에서는 부산시 주간선도로의 68개 주요 교차로를 중심으로 교통사고, 교차로 기하 구조, 강수량 등의 정보를 종합적으로 교통사고 발생에 대한 노드와 링크 단위의 위험도 예보를 하고자 하였다. 구체적으로, 운전자특성과 운전상황 같은 동적정보와 교차로 기하 구조데이터를 이용하여 각 상황에 맞는 상대적 사고발생 위험도를 산정하였다. 또한 사고유형을 '차대차', '차대사람'으로 분류하여 각각의 구체적인 사고발생 위험도를 산정하였다. 최종적으로는 산정한 결과 값에 기초하여 교차로 기반의 운전자 맞춤형 사고위험도 정보를 제공하고자 하였다. 사고예보정보에 따른 안전한 경로를 서비스함으로서 맞춤형 경로선택의 기회를 제공하며 운전자의 안전운행에 도움을 주고자 하였다.

This study analyses the types, related operations, facilities, and causes of chemical accidents in Korea based on the RISCAD classification taxonomy. In addition, human error analysis was carried out employing different human error classification criteria. Explosion and fire were major accident types, and nearly half of the accidents occurred during maintenance operation. In terms of related facility, storage devices and separators were the two most frequently involved ones. Results of the human error-based analysis showed that latent human errors in management level are involved in many accidents as well as active errors in the field level. Action errors related to unsafe behavior leads to accidents more often compared with the checking behavior. In particular, actions missed and inappropriate actions were major problems among the unsafe behaviors, which implicates that the compliance with the work procedure should be emphasized through education/training for the workers and the establishment of safety culture. According to the analysis of the causes of the human error, the frequency of skill-based mistakes leading to accidents were significantly lower than that of rule-based and knowledge based mistakes. However, there was limitation in the analysis of the root causes due to limited information in the accident investigation report. To solve this, it is suggested to adopt advanced accident investigation system including the establishment of independent organization and improvement in regulation.

The Process Safety Management (PSM) by the Law of Industry, Safety and Health has been performed for preventing major accidents of chemical plants since 1996. In terms of preventing chemical accidents more precisely, it is essential to develop a tool for quantitative risk assessment. For this, KOSHA (Korea Occupational Safety and Health Agency) developed an Integrated Risk Management System (IRMS). The system is designed to assimilate data on chemical plant hazards from external database, to integrate these data with location information(topographic and demographic), and to make them user-friendly accessible. The system consists of several main functions: display of five major Korean petrochemical complex layout display of equipment layout with its information utilizing the external database, zonation of the hazard effected area with consequence analyses, the most probable accident scenario generation, accident/incident database and calculation of frequency of accident using equipment reliability database, etc. The highlight of IRMS is to provide the risk contours using GIS(Geographical Information System) technology. IRMS is intended to manage hazardous installation more systematically and effectively, to reduce the number of accident remarkably, further minimizing production loss in the plant. The system is now under application to about 500 PSM sites as well as and emergency authorities in Korea by KOSHA (Korea Occupational Safety and Health Agency)

The Study lay Emphasised on to Investigate Human Related Causes of a Pointed End Equipment Accident and the Basic data for Analyzing Human-Error Prevention Program. Peter Son's Model of Human-Error Accident Causation and Cooper's Model of Safety Culture Were Applied to Analyze the Severe Cause of a Pointed End Equipment for Last 5 Years. Through to Analyzing the Cause of Equipment Accident of Human-Error, Expert's Opinion and Experience Theory Method was Reflected. The Analyses Showed What the Immature and Inexperient Error Were Major Causes of a Pointed and Equipment Accident. The Cause of Human-Error was Found with Respect to Human, Tasks, Acknowledge, Organization.

This paper suggests to standardize railway accident restoration types as the standardized code and to develop standard operation procedures(SOP) for the efficient railway accident management and recovery system. First of all, occurred damage types as the existing railway accident types in both domestic and foreign cases have been carefully analyzed and then reclassified. Therefore, this study suggested the combination of 3 distinct code factors: restoration class, restoration object, and restoration location to standardize them. In addition, temporary restoration SOP will play a major role in the railway accident database management system and SOP for the damage limitation and the prevention of accident spread.

A major issue for all nuclear stakeholders is to keep the probability of circumstances that could lead to core damage as low as possible. In addition, for NPP, appropriate accident management provisions are to be implemented to limit the consequences associated with an accident. Development and application of L2 PSA is a structured way to demonstrate that such objectives are achieved. The paper presents the efforts recently done in Europe to harmonize some best-practices in that field, from research area to risk assessment. The Fukushima Daiichi accident reiterated the importance of these activities and the need to efficiently reinforce the NPP safety based on risk assessment conclusions. New perspectives in Europe are briefly presented.

The safety accident of construction industries occur variously in other industries, including other industries, resulting in significant losses of human and material losses. In particular, General worker represents the highest safety accident rate each year, and the various types of accidents are the ones that show the greatest interest in the field, which is the most interesting job in the field. This study aims to identify trends in safety hazards and to analyze the accident severity for major types and influence factors.

이 논문의 목적은 항공기 상태가 정상상태에서 공항에 접근 착륙 중 발생한 사고로서 상업용 항공사에서 발생하는 사고를 예방하기위한 지침이 될 수 있는 사고예방 차원에서 중요한 이정표가 될 수 있다. 이 논문의 CFIT 사고의 주요한 분석은 1993년도부터 2002년까지 발생한 사고 중에서 괌사고, 목포사고 및 김해사고를 중점으로 사고원인분석을 실시하였다.CFIT 사고는 운항승무원에 의해서 사고 전에 충분히 인지하지 못하고 있다가 지상 장애물 또는 해면에 충돌하는 사고로 매우 치명적이다. 일반적으로 CFIT 사고는 대부분의 비행 중에 발생할 수 있지만, 보다 많이 발생하는 경우는 착륙중에 발생함으로 더욱 위험하다고 볼 수 있다.이 논문을 통하여 CFIT 사고를 예방하기위하여 운항승무원 교육 및 훈련을 할 필요가 있다고 사료되며 특별히 EGPWS(향상된 지상충돌경고장비)와 같은 장비를 항공기에 장착하기를 추천하며 항공사의 조직문화에 대한 연구가 더욱 요구된다고 판단한다.

Tuna purse seine fishery (TPF) constitute more than 60% of distant water fishery production in Korea based on a statistic of 2018, and 28 ships from four different companies were under operation at the western and central Pacific Ocean. On this research, common risk factors during TPF were investigated via enumeration of five years Korean fisherman's insurance payment statement, followed by some counterplans to diminish the accident rate. The accident rate of TPF on the Pacific Ocean peaked by 43.0% in 2014 and constantly decreased to 23.0% until 2018, presenting an average of 33.6%. Meanwhile, the accident rate on the Indian Ocean reached the highest point 55.1% in 2014 and declined to 11.6% in 2016, having an average of 24.7%. The average accident rate of the Indian Ocean scored 8.9% lower than the rate of the Pacific Ocean, but no statistic significance was observed. Depending on the process of operation, 'casting or hauling of net' was the most frequent part that people received an injury (40.4%). When the accidents were classified by their types, 'falling down' was the most recurrent cause of the injuries (28.5%). At the point of severity, the worst injuries were induced by crush hazard. Considering aforementioned accident frequency and severity, all the factors on the accident type list were divided into three different groups including high risk, moderate risk, and common risk. This study is expected to contribute to the reduction of occupational accidents during the work of fishermen and establishment of a safety management system for distance water fishing vessels.
