Pilots are indispensable and central to the aviation industry, with the relevance of their psychological stress and resultant human errors increasingly recognized as critical. This study aims to meticulously explore the interrelations between psychological stressors and associated factors among helicopter pilots, assessing the consequent effects on potential accidents and incidents. The study comprised active pilots from domestic helicopter airlines, with data collated through both focus group interviews (FGI) and comprehensive surveys. These data were subsequently analyzed using SPSS and AMOS for structural equation modeling. The results reveal that heightened psychological stress in helicopter pilots correlates with an increased incidence of human errors, which in turn, elevates the likelihood of potential safety incidents. Based on these findings, it is proposed that interventions designed to mitigate psychological stress among pilots could significantly reduce human errors and enhance overall aviation safety. This research provides crucial insights into specific ways to improve the operational conditions for helicopter pilots and strengthen the safety protocols within the aviation industry.

본 연구는 초, 중, 고등학교 안전사고 발생현황과 원인을 분석함으로써 학생들이 안전한 환경에서 교육의 궁극적인 목적을 달성할 수 있도록 예방시스템을 구축하는데 기초자료를 제공하기 위해 시도되었다. 데이터베이스는 2010-2014년 까지 충청남도 학교안전공제회에서 학교안전사고에 대해 원인별, 시간별, 장소별로 지급된 건수가 기록된 데이터를 기술통계를 통해 전체 건수와 백분율을 산출하였다. 연구 결과, 학교안전사고의 발생 건수는 연도가 지날수록 증가하였으며, 특히 초등학교의 경우 중학교나 고등학교에 비해 발생률이 높은 것으로 나타났다. 그리고 시간별 분석결과 휴식시간에 가장 높은 비율로 발생하였고, 사고 발생장소로는 운동장의 비율이 가장 높았으며, 사고 발생 원인으로는 학생 부주의로 인한 사고 발생의 비중이 가장 높았다. 안전은 인간의 가장 기본적인 욕구 중에 하나이므로 학교안전사고를 감소시키기 위해 학생 교사요인, 학교시설의 물리적 환경적 요인에 대한 총체적 대책마련이 필요하다고 할 수 있다. 본 연구결과를 바탕으로 학교안전사고를 감소시킬 수 있는 방안과 실효성 확인에 대한 추후 연구를 제언하는 바이다.

유류와 위험 유해물질(Hazardous and Noxious Substances, 이하 HNS)을 포함하는 위험물질의 해상운송 중에 발생하는 사고가 증가하고 있어, 이러한 위험물질 해양사고를 방지할 수 있는 예방대책을 마련해야 할 것이다. 이를 위해 국내에서 발생하는 위험물질 해양사고 자료(2002~2014)를 수집하여 인명 및 환경 위험도를 분석하였으며, 사고원인 규명 및 적절한 예방대책이 필요한 우선 안전관리분야를 파악하고자 하였다. 인명위험도는 선박 수리 및 탱커세정(tank cleaning) 작업과정에서 발생하는 폭발 및 인명사고 중 질식 등이 높은 것으로 분석되었다. 환경위험도는 충돌, 좌초 등에 의한 유출사고로 인해 발생하였다. 또한 비포장 상태의 위험화물을 선박에 적재 중 취급부주의로 인하여 유출사고가 일어났다. 다수의 사고는 적합한 안전장비 미착용, 취급 부주의 등 인적오류로 인한 사고로서 관리 감독을 강화하고, 주기적인 교육 훈련을 통하여 사고 저감이 가능하다. 위험물질 해양사고를 예방하기 위해서는 물질 자체 고유의 특성상 유해성과 위험성을 지닌 위험물질(유류와 HNS)에 대한 안전관리를 더욱 강화해야 한다.

There has been a significant decline in the number of rail accidents in Korea since system safety management activities were introduced. Nonetheless, analyzing and preventing human error-related accidents is still an important issue in railway industry. As a railway system is increasingly automated and intelligent, the mechanism and process of an accident occurrence are more and more complicated. It is now essential to consider a variety of factors and their intricate interactions in the analysis of rail accidents. However, it has proved that traditional accident models and methods based on a linear cause-effect relationship are inadequate to analyze and to assess accidents in complex systems such as railway systems. In order to supplement the limitations of traditional safety methods, recently some systemic safety models and methods have been developed. Of those, FRAM(Functional Resonance Analysis Method) has been recognized as one of the most useful methods for analyzing accidents in complex systems. It reflects the concepts of performance adjustment and performance variability in a system, which are fundamental to understanding the processes of an accident in complex systems. This study aims to apply FRAM to the analysis of a rail accident involving human errors, which occurred recently in South Korea. Through the application of FRAM, we found that it can be a useful alternative to traditional methods in the analysis and assessment of accidents in complex systems. In addition, it was also found that FRAM can help analysts understand the interactions between functional elements of a system in a systematic manner.

In order to prevent railway accidents due to human errors which have been recognized to be the most important cause in the railway accidents, human errors should have been controlled based on systematical analysis of the human errors, and countermeasures should be derived to reduce human error probability. Among several factors inducing human errors, task load (or task complexity) is representative. In order to reduce the human error, a systematic analysis should be undertaken to evaluate task load. In this study, task load according to task types of railway worker who are a safety critical staff have been quantitatively analyzed based on NASA-TLX(Task Load Index).

There is a limitation in Human faculty, especially, in the power of attention. Therefore, this paper will be studied to show that it is seeking the ability needed by traffic analysis as well as getting ability of aptitude to attribute to prevention of traffic accidents.

Human factors still plays a significant role in railway accidents. The accidents often resulted from multiple causes of hardware failures and human errors. So to ensure the safety of railway operations, human error should be effectively prevented and managed. Among several factors influencing human performance, task load (or task complexity) is well known as a major contributor to human error. In order to reduce the potential of human error, a systematic analysis should be undertaken to evaluate task load and to reduce it by modifying task process and/or education&training. In this paper, we proposed a systematic framework for railway industry to perform task analysis and to evaluate task load, and applied it to KTX operational tasks. According to the application study, we identified 14 generic task types of KTX operation. And also this paper shows the quantitative task load of those generic tasks which were analyzed by NASA-TLX method.

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.
