Accident analysis models were developed to improve the construction site safety and case studies was conducted. In 2016, 86% of fatality accidents occurred due to simple unsafe acts. Structure related accidents are less frequent than the non structure related causes, but the number of casualties per accident is two times higher than non structure one. In the view of risk perception, efforts should be given to reduce accidents caused by low frequency - high consequence structure related causes. In case of structure related accident, structural safety inspection and management (including quality), ground condition management / inspection technology, and provision of risk information delivery system in case of non structure related accident were proposed as a solution. In analysis of relationship between safety related stakeholder, the main problem were the lack of knowledge of controller and player, loss of control due to duplicated controls, lack of communication system of risk information, and relative position error of controller and player.

Korea is becoming an aged society as well developed country. Accident rates of elderly workers are increased. When elderly workers injured, elderly workers are more likely to die as a result, and they take longer to recover than young workers. Thus the cost to industry per individual accident gets higher for elderly workers. If information on the occupational accidents of elderly workers could be collected and analyzed for the purpose of preventing occupational accidents, we would be able to get rid of accidents of elderly workers. The accidents of elderly workers in small manufacturing factories were considered in this study. 97 accidents, which occurred in 1995-1998, were investigated. These accidents were analyzed in terms of sex, work period, cause of accident and form of accident. The accidents of elderly workers in small manufacturing factories are numerous and are often serious and worthy of greater attention than they have received. Successful strategies for accident prevention depend on effective analysis.

Background: External-cause mortality is an important public health issue worldwide. Considering its significance to workers' health and inequalities across industries, we aimed to describe the state of external-cause mortality and investigate its difference by industry in Republic of Korea based on data for 2018. Methods: Data obtained from the Statistics Korea and Korean Employment Information System were used. External causes of death were divided into three categories (suicide, transport accident, and others), and death occurred during employment period or within 90 days after unemployment was regarded as workers' death. We calculated age- and sex-standardized mortalities per 100,000, standardized mortality ratios (SMRs) compared to the general population and total workers, and mortality rate ratios (RRs) across industries using information and communication as a reference. Correlation analyses between income, education, and mortality were conducted. Results: Age- and sex-standardized external-cause mortality per 100,000 in all workers was 29.4 (suicide: 16.2, transport accident: 6.6, others: 6.6). Compared to the general population, all external-cause and suicide SMRs were significantly lower; however, there was no significant difference in transport accidents. When compared to total workers, wholesale, transportation, and business facilities management showed higher SMR for suicide, and agriculture, forestry, and fishing, mining and quarrying, construction, transportation and storage, and public administration and defense showed higher SMR for transport accidents. A moderate to strong negative correlation was observed between education level and mortality (both age- and sex-standardized mortality rates and SMR compared to the general population). Conclusion: Inequalities in external-cause mortalities from suicide, transport accidents, and other causes were found. For reducing the differences, improved policies are needed for industries with higher mortalities.

In 2015, the number of senior citizens aged 65 and over in Korea was 6,662,400, accounting for 13.1% of the total population. Along with these social phenomena, risk information related to the elderly is increasing every year. In particular, a fall accident caused by a fall can cause serious injury to an elderly person, so special attention is required. Therefore, in this paper, we implemented a system that monitors fall accidents and informs them in real time to minimize damage caused by falls. To this end, beacon-based indoor location positioning was performed and biometric information based on an integrated module was collected using various sensors. In other words, a multi-functional sensor integration module was designed based on Arduino to collect and monitor user's temperature, heart rate, and motion data in real time. Finally, through the analysis and prediction of measurement signals from the integrated module, damage from fall accidents can be reduced and rapid emergency treatment is possible. Through this, it is possible to reduce the damage caused by a fall accident, and rapid emergency treatment will be possible. In addition, it is expected to lead a new paradigm of safety systems through expansion and application to socially vulnerable groups.

Accidents are the leading cause of death in children worldwide. The purpose of this study is to use basic data of safety education, counseling, and information available regarding accident prevention to examine the degree of mothers' accident prevention practices for their children. Data were collected from June to October, 1998 from 587 mothers including 2 University hospitals located in Seoul and Kyoungki-Do. By using the 30 item questionnaire, which was created by researchers through literature review, the degree of mothers' accident prevention practices for their children was measured. The degree of accident prevention practices of mothers shown ranged 70-118 and averaged 3.19. Compared to the composit area average score, drug keeping had the highest score of 3.57 The next highest scores and traffic safety(3.41), and supervision of child(3.30). Prevention against burning was the lowest point at 2.58. With the respect to the demographic characteristics, there were stastically significant differences in the mothers' education(F＝4.291, p＝.014), type of residence(F＝3.979, p＝.008), and child developmental age (F＝5.275, p＝.001). The degree of accident prevention practices of mothers were relatively high. But the area which showed the low degree of accident prevention practices, required nurses' active education, counseling, social interest and support, and mass media participation.

In this paper, we implement a Dashcam system capable of shooting 360 degrees using a Raspberry Pi, shock sensors, distance sensors, and rotating camera with a servo motor. If there is an object approaching the vehicle by the distance sensor, the camera rotates to take a video. In the event of an external shock, videos and images are stored in the server to analyze the cause of the vehicle's accident and prevent the user from forging or tampering with videos or images. We also implement functions that transmit the message with the location and the intensity of the impact when the accident occurs and send the vehicle information to an insurance authority with by linking the system with a smart device. It is advantage that the authority analyzes the transmitted message and provides the accident handling information giving the user's safety and convenience.

Purpose: In this study, the goal is to analyze this case to prevent the same accidents when using one-shot rifle. Methods: Detailed analysis of damaged parts must first be made in order to determine the cause of the abnormal explosion. The cause of abnormal operation can be determined by analyzing the information of damaged components and the firing mechanism of the weapon step by step. Also we can refer to a statement of shooter, witness and accident scene situation. Based on this theory, cause of abnormal firing can be narrow down. Results: Fracture of pin for fixing firing and latch is cause of abnormal operation of firing. Conclusion: It is deemed that periodic inspection and fundamental improvement of the structure are required to prevent the same accident as this.

IMO에서는 선박운항기술에 ICT기술을 융합하여 해양사고를 예방하는 e-Navigation의 도입을 추진하고 있다. 국내에서도 해양사고의 취약계층인 어선 및 연안을 항해하는 소형선박을 대상으로 한국형 e-Navigation을 개발하고 있다. 그러나 한국형 e-Navigation의 성공적인 개발을 위해서는 현재까지 진행된 개발성과를 평가하고 개발 방향성을 재정립할 수 있도록 개발성과를 평가할 수 있는 지표의 개발이 필요하다. 따라서 본 연구에서는 주요한 해양사고인 충돌사고를 중심으로 e-Navigation 서비스의 개발목표에 맞춘 평가지표를 개발하고자 하였다. 본 연구에서는 RCA기법과 FTA 기법을 활용해 해상 충돌사고 발생 근본원인을 도출하고 이를 정량화하여 e-Navigation 서비스를 위한 충돌사고 평가지표를 개발하였다. 해당지표는 e-Navigation의 개발지표 및 충돌사고 분석을 위한 지표로 활용되어 해양사고 저감에 도움이 될 것으로 사료된다.
