It is very difficult to evaluate the impact speed, who caused the accident and what the injury risk of the vehicle occupants was from the outcome of the accident. That's the main reason why there are so many insurance fraud related to vehicle accident. In this study, a vehicle crash accident suspected to an insurance fraud had been reconstructed to evaluate crash speed and the relationship between the crash accident and passenger injury risk. To do this, the scene was reconstructed based on accident investigation report and three vehicle crash tests were done at 27kph, 37kph and 70kph. The crash speed of 27kph and 37kph were chosen based on the damaged vehicle and 70kph was chosen based on the driver's statement. Based on the damage of vehicle and dummy injury measure, impact speed is estimated around 20 to 30kph and the dummy measures show that the passengers are not seems to be severely injured in this speed range.

Objectives: This study was conducted to determine firefighters' work-related accident rate and investigate the factors affecting their on-site safety. Methods: We developed a web-based self-reported questionnaire designed to inquire into firefighters' work-related accident experience and the factors (4M; Man, Machine, Media, Management) affecting firefighters' on-site safety. We distributed questionnaires to all members of firefighting organizations in South Korea by e-mail and 9,149 were returned, resulting in a response rate of 23.1%. Results: Fifteen point seven percent of the respondents reported work-related injuries within the past one year, and 35.1% answered that current accident investigation reports are not helpful for preventing the same accident from recurring. Among the 4M factors, the one most affecting firefighters' on-site safety in the order of priority is the Man factor, followed by Machine, Media, and Management. However, the results from detailed sub-categorical factors showed some differences. 'Lack of human resources', one of the Management factors, was the most influential (70.3%), followed by 'worn-out equipment' under the Machine factor (67.2%). The viewpoint of elements of the Man factor including 'forgetting instructions' and 'fatigue and illness' were significantly different according to firefighters' rank. The higher the firefighter's rank, the more they answered 'forgetting instructions,' while the opposite was the case for 'fatigue and disease'. Conclusions: The present firefighters' accident investigation report needs to be improved, and the 4M method could prove very useful. In addition, it is necessary to set up a proper firefighters' accident investigation and prevention system.

국내외 연구들은 무인항공기 사고의 주원인으로 인적요인을 지목하고 있고, 이러한 인적요인을 효과적으로 분석하는 기법으로 HFACS를 소개하고 있다. 현재까지는 HFACS를 이용해 무인항공기 사고의 인적요인을 분석했던 국내외 사례는 주로 군용 무인항공기가 대상이었는데, 항공사고를 유발하는 인적요인 정보를 분석하여 객관적 원인 규명과 유사 사고 예방 도구로 사용할 수 있는 HFACS가 국내 민간 무인항공기 분야에서도 활용이 필요한 시점이다. 특히, 국내 민간 무인항공기의 성능과 운용 여건을 고려한 HFACS 적용중점을 식별한다면 사고 발생 시 원인 규명과 재발 방지에 큰 도움이 될 것으로 예상된다. 본 연구는 HFACS version 7.0을 근간으로 우리나라 항공철도사고조사위원회가 수행했던 사고조사 결과보고서 자료를 분석하여 국내 민간 무인항공기 사고조사에 활용할 수 있는 HFACS 적용중점을 식별하였다.

지하사고가 발생할 경우 신속하게 원인을 파악하고 인적, 물적 피해를 줄여야 한다. 지하사고조사위원회는 발생한 사고의 원인을 규명하고 이후 동일한 사고가 발생하지 않도록 대응방안을 마련하는 역할을 한다. 그러나 지하사고조사위원회 운영 기간이 최소 6개월에서 최대 9개월까지 활동할 수 있도록 법에 명시되어 있어 실질적으로 동시간대에 추진 중인 건설 사업에서 사고조사보고서를 인용하고 검토를 통해 자체사업에 반영하기에 어려워 보인다. 본 연구에서는 기존에 3개월이 소요되던 자료수집과 분석을 최대 1개월 이내로 단축시킬 수 있도록 현장에 출동하여 자료를 수집하고 디지털트윈으로 구현하고 제공함으로써 지하사고조사위원회가 의사결정을 신속하게 할 수 있는 기술개발 전략을 수립해보고자 했다. 연구결과 5개 기술개발 분야인 지상 데이터 수집·전송기술, 지상안전 데이터 생성기술, 디지털트윈 기반 지하안전 분석·가시화 기술, 디지털트윈 기반 지오앰뷸런스 구축·운영 기술, 디지털트윈 기반 지오앰뷸런스 표준화 및 법제도 연구를 도출할 수 있었다. 제시된 기술이 개발된다면 기존대비 신속한 의사결정을 통해 사고현장을 줄이는데 기여할 수 있을 것으로 보인다.

공공교통기관인 철도에 요구되는 가장 기본적인 요건은 수송의 안전을 확보하는 것이다. 타 교통수단보다 철도가 비록 안전하지만 대량교통수단에서 일단 사고가 발생하면 그 피해규모는 크다. 철도운영자 및 국가에서는 이러한 철도의 사고발생을 사전에 방지하기 위하여 많은 노력을 기울이지만, 사고를 근절시키는 것은 불가능하다. 따라서 사고발생을 최대한 줄이기 위하여 다양한 방안들이 강구되고 있는데, 본 논문에서는 최근 들어 그 중요성이 부각되고 있는 인시던트 보고제도와 안전문화에 대하여 살펴보고자 한다. 본 논문에서는 미국 및 영국 등 선진외국에서 항공분야에서의 인시던트 보고 제도에 대한 사례를 분석하여 보았으며, 또한 철도분야에서도 인시던트 보고 제도가 도입된 영국사례를 중심으로 이에 대한 분석을 통하여 우리나라에서의 철도분야 인시던트 보고 제도의 필요성과 방향에 대하여 논의하였다. 또한, 사고방지 및 안전향상을 위하여 필요한 것이 철도운영회사 및 관련기관의 철도안전에 대한 문화의식이다. 올바른 철도안전문화의 정착이야말로 가장 확실하게 철도사고를 예방하고 철도안전을 향상시킬 수 있는 방안인 것이다. 따라서 철도기업에서의 철도안전문화에 대한 이해 등에 대하여 본 논문에서 검토하고자 한다.

Construction is among the most dangerous industries with numerous accidents occurring at job sites. Following an accident, an investigation report is issued, containing all of the specifics. Analyzing the text information in construction accident reports can help enhance our understanding of historical data and be utilized for accident prevention. However, the conventional method requires a significant amount of time and effort to read and identify crucial information. The previous studies primarily focused on analyzing related objects and causes of accidents rather than the construction activities. This study aims to extract construction activities taken by workers associated with accidents by presenting an automated framework that adopts a deep learning-based approach and natural language processing (NLP) techniques to automatically classify sentences obtained from previous construction accident reports into predefined categories, namely TRADE (i.e., a construction activity before an accident), EVENT (i.e., an accident), and CONSEQUENCE (i.e., the outcome of an accident). The classification model was developed using Convolutional Neural Network (CNN) showed a robust accuracy of 88.7%, indicating that the proposed model is capable of investigating the occurrence of accidents with minimal manual involvement and sophisticated engineering. Also, this study is expected to support safety assessments and build risk management systems.

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.
