기술발전에 따라 건설현장은 스마트 안전관리기술을 활용한 안전관리의 변화가 예고되고 있다. 중대재해처벌법 시행(22.1.27)이후 50인 이상 사망사고는87건(96명)으로 전년 동기109건(111명)대비22건(20.2%), 15명(13.5%)감소한 것으로 나타났다(국토교통부,2022). 반면에 단순비교지만 일본0.14%, 미국0.37%, 영국0.03%에 비해 한국의 재해율이 높으므로 다양한 안전관리활동의 과제가 남아 있다. 이에 아차사고 유형이 건설현장 특성간의 민감도모델 제시를 기반으로 근본적인 재해관리가 연구의 목적이다. 이를 이루기 위해 국토교통부의 아차사고 발굴데이터를 분석하여 유형을 분류하고, 공사기간, 공사규모, 신체부위 등의 요인간의 아차사고 민감성요인에 대하여 Bayesian Network를 이용하여 아차사고에 영향을 주는 모델링을 제시하고자 한다.

A near miss is an unplanned event that did not result in injury/illness, or property damage, but had potentials to do so. The importance of the near miss has been emphasized by many researchers and organizations. However, only a few studies have quantitatively approached the near miss from the viewpoint of safety culture. The purpose of this study is to investigate the current status of near miss reporting activities in manufacturing workplaces in Korea. It also aims to understand how the activities related with the safety culture and the occurrence of industrial accidents. To this end, a survey was conducted on manufacturing workplaces and the results were analyzed. As a result, there was a marked difference in the perception on near miss according to whether or not the near miss reporting activity was conducted. However, it was found that only 56% of the workplaces were carrying out the reporting activities. It was found that the number of near misses reported varied depending on the reward. Although no correlation could be found between whether or not the near miss reporting activities were carried out and the history of industrial accidents occurred, it was found that safety culture level was hier at the workplaces conducting the activities.

Purpose: The purpose is to prevent accidents by predicting disasters through the analysis of near-miss. Method: In this study, a near-miss literature review and data were collected at construction sites, and a questionnaire survey was conducted to use logistic regression analysis and decision tree analysis to classify the possibility of near-miss connection. Result: As a result of analyzing the effects of near-miss types on mental, physical, and safety habits and behaviors, the factor with a high influence on the body is the need for near-miss management, the type of job is electricity·information communication, and health status in order, and the mental factor is the construction scale The influence was high, and the factors with the highest influence on the habit behavior factors were analyzed in the order of experience, number of serious injuries, and occupation in order of illusion, inappropriate work instructions, and body parts. Through decision tree analysis, factors and patterns that affect the possibility of a near-miss being a surprise accident were identified. Conclusion: Construction site officials consider the observation of near-miss and mentally and physically. Specific management of the relevance of physical aspects to near-miss should be implemented, and a work environment in which serious accidents are reduced is expected through personnel allocation, work plans, work procedures and methods, and feedback so that inappropriate work instructions do not lead to near-miss.

This study intended to exploratively testify human error causing factors for railway traffic controller, using AMOS structural equation model. Through literature survey, fatigue and stress as exogenous variable, errors in information process such as cognitive, memory, storage, and execution error as endogenous variable, and accident and incident(near-miss) as dependent variable were set up. Results based on AMOS using 201 railway traffic controllers' questionnaire showed that a clear causality loop like as 'stress ${\rightarrow}$ memory error ${\rightarrow}$ storage error ${\rightarrow}$ incident(near-miss) ${\rightarrow}$ accident' is formed. This result suggests that for the purpose of mitigation of traffic controller's accident, it is so necessary to reduce memory and execution error in the information processing process based on the effective management of stress, as the precedent of them.

준해양사고 통보제도(Marine Incidents Reporting System)는 우리나라의 선박소유자 및 선박운항자가 선박의 구조 설비 또는 운용과 관련하여 시정 또는 개선되지 않으면 선박과 사람의 안전 및 해양환경 등에 위해를 끼치거나 위해를 끼칠 수 있는 사태로서 해양사고를 제외한 사건이나 사고에 대하여 자율적으로 중앙해양안전심판원에 통보하도록 하여 심판원은 이를 분석하여 교훈을 발굴하고 정기적으로 업계에 전파하여 해양사고 예방에 도움이 되고자 하는 제도이다. 동 제도는 2010월 4월 조기 시행 한 후 시행 5년차에 접어들었지만 홍보부족, 선박의 특수성, 제도적 장치의 부족으로 통보제도 운영에 어려움을 격고 있다. 본 논문에서는 IMO 해양사고조사코드와 국내외 유사 준사고 보고제도 분석 후 통보대상자를 대상으로 준 해양사고 통보제도의 현황에 대한 설문을 실시하고 분석함으로써 동 제도의 활성화 방안을 제시하고자 한다.

기계·기구, 설비 등(이하 "기계설비")의 주요 위험장소에는 작업자를 통제, 격리하기 위해 방호가드를 고정·설치하는 등 안전사고에 대비하고 있다. 다만 방호가드가 개폐가 용이한 구조일 경우 기계설비 등의 작동 중 작업자 임의 개방에 의한 사고위험에 그대로 노출될 우려가 있어 개폐가 가능한 구조의 방호가드에는 기계설비 가동조건과 연동회로가 구성된 인터록장치를 설치하여 안전사고에 대비하는 것이 일반적이다. 다만 인터록장치는 대부분 기계설비의 가동조건과 하드와이어드(hard-wired)로 결선된 단순 구조가 아닌 PLC(Programmable Logic Controller), 터치판넬, 통신장치 등과 다양하게 다소 복잡한 구조로 설치되어 있고, 인터록장치에 사용되는 센서도 구조, 기능, 사용처 등에 따라 매우 다양화되어 방호도어에 설치되는 안전센서의 사양 선정이 잘 못되거나 설치 후 관리가 미흡할 경우 오작동, 기능해지 등으로 인해 또 다른 사고위험에 그대로 노출될 우려가 있다. 따라서 방호가드에 설치된 인터록장치의 기능해지, 관리소홀 등으로 인해 발생한 사고사례, 아차사고 등을 통해 인터록장치 성능 유지관리를 위한 기술적 사항에 대한 기준을 마련할 필요가 있다.

This paper presents a method that identifies the unsafe behaviors at the level of near-misses using image analysis. The method establishes potential collision hazardous area in earthmoving operation. It is implemented using a game engine to reproduce the dangerous events that have been accepted as major difficulty in utilizing computer vision technology to support construction safety management. The method keeps realistically track of the ever-changing hazardous area by reflecting the volatile field conditions. The method opens a way to distinguish unsafe conditions and unsafe behaviors that have been overlooked in previous studies, and reflects the causal relationship which causes an accident. The case study demonstrate how to identify the unsafe behavior of a worker exposed to an unsafe area created by dump trucks at the level of near-misses and to determine the hazardous areas.

교통안전공단이 운전자 400명을 대상을 졸음운전 실태를 조사한 결과 최근 1주일간 10명 중 4명이 졸음운전을 경험했으며, 그 중 19%는 사고가 날 뻔한 '아차사고' 경험이 있는 것으로 나타났다고 밝혔다. 이에 따라 운전자들의 졸음운전을 예방하기 위한 시스템의 존재가 시급하다는 것을 알 수 있다. 이에 본 논문에서는 운전자의 졸음운전 사고를 예방하기 위한 운전 방지 기법을 제시한다.

This study highlights the theme of human error emerging as a critical issue in the railroad industry, conducting exploratory research on the effects of health, cognition, and safety climates on safety behavior and accidents using an empirical method. The statistical results based on questionnaires received from 204 train drivers indicate that psychological fatigue, cognitive failure, and internal locus of control as individual variables and CEO philosophy and behavior of immediate boss as organizational variables have significant relationships with safety behavior, while cognitive failure, CEO philosophy, behavior of immediate boss, and education were found to be significant variables with respect to accidents. Furthermore, unsafe behavior such as mistakes and violations showed negative effects on near misses and responsibility accidents, respectively. Based on these results, effective alternatives and countermeasures needed to mitigate human error were posited.

This study was intended to validate and develop the driving stress coping behavior scale. In a preliminary investigation, literature studies on the driving stress and open questionnaire were administered and examined in four regions in Korea. As a result, 64 items driving stress questionnaire were developed. In the study, this Driving Stress Coping Behavior Scale(DS-CBS) was examined to 372 drivers located seven regions in Korea. The factors analysis revealed 2 meaningful factors[(Good Coping: GC), (Bad Coping: BC) with 24 items. When internal consistency for each 2 factor was calculated, all sub-scale revealed a satisfactory level of Cronbach's α. Also, correlations with Driver Coping Questionnaire(DCQ) and risk driving behaviors(speed driving, drunken driving, traffic violation, offence accident, defence accident) supported consistently validity of the Driving Stress Coping Behavior Scale(DS-CBS). Also, We investigated the influences of 'Good Coping', 'Bad Coping' consisting of driving stress coping behavior, on traffic accidents risk. As a result, 'Good Coping' and 'Bad Coping' influenced traffic accidents risk. 'Good Coping' had decreased effects, the other side 'Bad Coping' had increased effects on traffic accidents risk(TARI).
