Objective: The purpose of this study was to investigate the effect of situational awareness on ship collision accidents in Korea coast. Background: The lack of situational awareness of maritime officers is reported to be a major cause of marine accidents. Research on situational awareness in Korea was not active. Especially, situation awareness research through analysis of accident data is very rare. Method: Using archival data on ship collision accidents that happened in the costal sea of Korea from 2017 to 2019, it was analyzed what types of situation awareness errors were related to ships" collision. The differences in situation awareness errors were analyzed based on collision ship types and encounter situations. Results: The error in the situation awareness level 1 was 67%, while the error in the situation awareness level 2 and 3 was 33%. The most parts of level 1 error were due to the negligence of watch keeping until collision and the continuous monitoring neglect after recognizing the collided ship from far distance. The main errors in the situation awareness level 2 and 3 were the misjudgment of risk situation, the error in the judgment of safe course and speed, misunderstanding and wrong application of safety regulations and misjudgment of future action of the other ships. The ratios of these errors were different according to the type of collision ships and the encounter situation. Conclusion: Collision accidents in the domestic coast were mainly due to the negligence of watch keeping, including the continuous monitoring neglect after recognizing the collided ship from far distance. There is a need for measured to prevent the watch keeping neglect of navigators. Depending on the type of ship and the situation encountered, other appropriate collision prevention measures are needed. Application: The results of this research might help to design human interface of ship equipment and to train maritime officers.

Objective: This study aims to provide foundation data to prevent industrial accidents by extracting insights from the analysis of the Characteristics of the victims of Industrial Accidents in 2020. Background: South Korea faced various industrial accident occurrences and the Korea Occupational Safety and Health Agency (KOSHA) conducts an industrial accident survey every year to produce statistical data related to various industrial accidents. However, since the report is mainly composed of descriptive statistical analysis and provided, it is difficult to conduct an in-depth analysis to prevent industrial accidents. In order to prevent industrial accidents, not only a basic analysis of industrial accidents but also a detailed analysis of the victims of the industrial accidents is required. Therefore, this study intends to provide basic data for the prevention of industrial accidents in the future by analyzing the characteristics of the victims of industrial accidents based on the 2020 Industrial Accident Report. Method: To analyze the data from the Industrial Accident Cause Investigation Report in 2020 of KOSHA, the cross-tabulation analysis by the Pearson's Chi-square Test was used between each factor, such as the industry type and the business size, the workers' age, the accident pattern, the work period and the accident year. And the results of the statistical significance and the relationship on each factor are interpreted and finally, the meaning of the analysis was described. Results: The results suggested that there are significant differences between the victims of industrial accidents and industry type, the size of business, the workers' age, the accident pattern, the work period, and the accident year. This study also discovered that there are significant differences in the disaster types and number of industrial victims. Conclusion: In this study, the relationship and meaning between victims of the industrial accident and various influence factors that can affect the accidents of the industrial accidents were analyzed.

오주석,이의용,류준범,이원용 한국교통연구원 2015 交通硏究 Vol.22 No.4

Unlike South Korea's overall declining trend of traffic accidents and related injuries, traffic accidents by elderly drivers are showing an increasing trend. Several studies suggest the changing of human factors due to aging, their effect on accidents, and accident prevention policies such as returning drivers’ license or posting elderly driver signs on vehicles. However, none of these have been effective in decreasing elderly drivers' traffic accidents. This study aimed to explore elderly drivers' typical traffic situations and their human errors related to accidents. We conducted traffic accidents analysis and through result analysis discovered significant differences in the degree of accidental severity and the mean number of fatalities between “early elderly drivers (65-74)” and “late elderly drivers (75+)”. Also, the characteristics and differences of older drivers' accidents were described by related accidental situations, vehicle types, and human errors. These results prove the need of age diversification on accident prevention policies for elderly drivers. The details of the results will be useful to train and educate elderly drivers to prevent traffic accidents and secure safe mobility. 우리나라의 전반적인 교통사고 피해 추세와는 달리 65세 이상 고령운전자들에 의한 교통사고 피해는 증가추세를 보이고 있어 해결이 시급한 사회문제로 떠오르고 있다. 그동안 고령자의 교통사고 예방을 위해 노화에 따른 인적요인의 변화 특성이나 교통사고 특성 등에 관한 연구 결과들과 운전면허 자진반납 유도나 고령운전자 표지 부착 등 다양한 고령운전자 교통사고 예방대책안이 제시되었으나 아직까지 눈에 띄는 성과를 보이지는 못하고 있다. 본 연구에서는 고령운전자들의 교통사고 기록을 인적요인과 사고상황, 사고관여 차종 및 용도 등 주요 변인들에 대해 교차분석을 실시하여 고령운전자들이 취약성을 느끼는 교통상황과 고령운전자 교통사고에 관여하는 인적요인의 특성을 고령자 연령집단별로 밝히고자 하였다. 분석 결과, 고령운전자들이 취약한 특정 사고상황 및 관련 인적요인과 주요 차종들이 도출되었다. 또 고령운전자 세부연령 집단 내에서도 연령의 증가에 따라 75세 이상의 후기 고령자 집단에서 사고 발생 시 상대적 위험도가 더 큰 것으로 나타났으며, 65세 이상 75세 미만 초기 고령자들과 75세 이상 후기 고령자들 사이에서는 사고 관여 차종 및 용도나 이들이 취약성을 드러내는 사고상황에서 차이를 보이는 것으로 확인되었다. 이와 같은 결과는 고령운전자들에 대한 안전대책 역시 연령 증가에 따라 다각화 되어야 할 필요성이 있음을 증명하고 있으며, 향후 고령운전자들의 교통사고 예방 및 안전한 이동성 확보를 위한 교육훈련의 기초자료로 활용될 수 있을 것이다.

This study aims to find out the current situation and the plan of safety accidents of infants and young children in the home on the background that social demand for safety issues in the home is steadily increasing. The results of this study are as follows. First, in case of accidents among children and infants at home, the accidents of boys are more frequent than girls, and the most accidents occur in summer. As children enter the infancy, accidents in the bathroom are frequent, so care must be taken to prevent accidents. Second, the online survey results for mothers of infants and toddlers (1,000 copies) showed that the most common types of accidents were crash or bump accidents, slippage and fall accidents. Careful attention should be given to the placement of furniture and appliances in the home and to building finishes (e.g. anti-skid). Third, assuming additional safety prevention facilities in the home, respondents were willing to pay about 50,000 won. This implies that most households in Korea are very passive in paying additional installations for their children"s home safety issues, which requires raising awareness about the safety of homes and active response by construction companies. Fourth, as a result of calculating the monthly average WTP for the provisional "safety prevention fee", it was found to be 28, 035 won per month. It is estimated that the formation of Korean safety prevention burden market of about 42 billion won per month and 512 billion won per year for infants and young children in the home, indicating this is important from a housing management and policy perspective.

This study aimed to enhance the effectiveness of the disaster site situation management following building collapse accidents. Thirteen collaborative functions were categorized into four groups: (1) situation general, (2) on-site response, (3) public support, and (4) resource support. Subsequently, essential information elements required for performing each function were identified. The tasks outlined in the crisis management manual relevant to disaster situation management were analyzed. Actual cases of building collapse accidents were examined, and data reported by response agencies were reviewed. Furthermore, considering the previously derived information elements and the unique characteristics of building collapse accidents, this paper proposed that collecting property damage information for buildings should be deemed a fundamental requirement for disaster site situation management. Given that this essential information provides detailed task-specific elements for managing disaster site situations related to building collapse accidents, expediting on-site disaster management can be achieved by prioritizing the collection of pertinent information during a disaster.

사고 및 음주운전자들의 운전행동결정요인 특성이 위험행동 및 교통사고에 미치는 영향: 경로분석 연구

오주석,이순철 대한교통학회 2007 대한교통학회지 Vol.25 No.2

Speeding and drunken driving make drivers fail to detect hazards and cope with various driving situations. These behaviors also raise the possibility of being involved in traffic accidents and tend to increase the number of fatalities. The authors compared the driving behavior determinants of a reckless drivers group, consisting of individuals who have committed traffic accidents or offended regulations through drunken driving, with a normal drivers group. In the results, the reckless drivers group showed high scores of 'speeding' and 'drunken driving', and they also stated that they had more experiences of speeding, drunken driving and traffic accidents. In the path analysis study, it was found that the impacts of the reckless drivers group's 'risk sensitivity' and 'situational adaptability' on traffic accidents were stronger than those of normal drivers. This means 'risk sensitivity' and 'situational adaptability' can explain the origins of traffic accidents better in the reckless drivers group than accidents of the normal drivers group. 과속과 음주운전 행동은 운전자로 하여금 교통상황에 잠재된 위험을 발견하고 적절하게 대처하지 못하도록 하여 교통사고 발생 확률을 높일 뿐만 아니라 사고 발생시 피해정도가 심하고 이 행동들에 내포하고 있는 위법성은 심각한 사회적 문제라고 할 수 있다. 사고 및 음주운전자 집단과 일반운전자들의 운전행동결정요인과 운전행동을 비교한 결과, 사고 및 음주운전자들의 ‘과속운전행동 점수와 ‘음주운전행동 점수가 일반운전자들보다 높았다. 또 사고 및 음주운전자들은 실제 운전행동에서도 일반운전자들보다 과속운전과 음주운전을 더욱 많이 하고 있었으며, 교통사고에서 가해자가 된 경험도 더 많았다. 경로모형 결과에서는 사고 및 음주운전자 집단의 위험감수성 부족 요인과 상황적응성 부족 요인, 과속운전행동 요인이 교통사고 가해경험에 미치는 영향이 일반운전자 집단에 비하여 더욱 크게 나타났고, 사고 및 음주운전자들의 운전행동결정요인들 가운데 위험감수성과 상황적응성의 수준이 교통사고 가해경험을 더 잘 설명하였다.
