The traffic accident reports that are generated by the Traffic Broadcasting Networks(TBN) are unstructured data. It, however, has the value as some sort of real-time traffic information generated by the viewpoint of the drives and/or pedestrians that were on the roads, the time and spots, not the offender or the victim who caused the traffic accidents. However, the traffic accident reports, which are big data, were not applied to traffic accident analysis and traffic related research commonly. This study adopting text-mining technique was able to provide a clue for utilizing it for the impacts of traffic accidents. Seven years of traffic reports were grasped by this analysis. By analyzing the reports, it was possible to identify the road names, accident spot names, time, and to identify factors that have the greatest influence on other drivers due to traffic accidents. Authors plan to combine unstructured accident data with traffic reports for further study.

The major purpose of this study is to find the problems that the statistics of industrial accidents showed and to prevent the preventive countermeasures for effective security management. An industrial accident is a disease resulting from exposure during employment to condition or substance detrimental to health or life. This is caused by the conditions of employment and is not projected by the man. This results generally from the comprehensive factors. The claiments of 1990 are 7,542,752 members and the economic deficit is up to 2,696,757 million won. Because of this severe damage, the preventive of the industrial accident is highly required. The way of preventive countermeasures could be presentation as follows. First, for securing the safety, precaution about the tools, machineries and working condition is needed from the time of installation. Second, a traing system for the managerial class the specialists or engineers should be established. Cultivation of the appropriate personnel and enhancement of technique for safety are prerequists for reduction of the industrial accidents. Third, the health checkup system must be improved. For the prevention of the occupational disease and good health of the workes, experts who knows workers health must be appointed. In conclusion, industrial accident is not unavoidable result of the advance of the industries but the result of the incapability of management that can not meet the requirement necessary for the prevention of industrial accident. Therefore, each corporation should be regard the above mention and make effective safety control that is free from the industrial accident. The implement of organizational safety programs, similar to the application of company health plan, involves shared administrative responsibilities among top executive line personnel, staff specialists, first line supervisors, and organizational employment.

The purpose of this study is to examine the effect of subjective overwork on health and the moderating effect of risk perception in the relationship between subjective overwork and health. The data used in this study are the fourth Korean Working Condition Survey (KWCS) conducted by Korea Occupational Safety and Health Agency (KOSHA) in 2014. The items related to actual working hours, subjective overwork, health, and risk perception were used. A total of 18,508 workers who are 1) waged workers, 2) work more than three days a week, 3) work more than 21 hours a week, 4) work longer than preferred work hours or work as longer as they desired were selected. Hierarchical regression analysis was performed to identify the effect of actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage on health and to determine the moderating effects of prevalence of risk and lethalness of accident damage. As a result, actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage had an effect on worker's health problems. Second, lethalness of accident damage had a moderating effect in the relationship between subjective overwork and health. These results suggest that organizations should manage worker's environmental factors and other threats that could increase the lethalness of accident damage.

The adjudication of Korean Maritime Safety Tribunal (KMST) was analyzed to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) in stow net fishing vessel from 2015 to 2019. The personnel's carelessness was the most common in 29 out of 33 accidents (87.9%), followed by 25 cases (75.8%) of inadequacy of instructions, 24 cases (72.7%) of inadequacy of education on hazard factor, 20 cases (60.6%) of no personal protection equipment, 18 cases (54.5%) of poor guard, 17 cases (51.5%) of inadequacy of work method, 16 cases (48.5%) of absence of emergency stop button, 14 cases (42.4%) of work practice of poor safety precautions that affected more than 40% of all accidents as accident causes. These causes had a strong influence on each other, and the ratio of accident causes is high. With this relationship, accidents can be prevented or the severity of human injury can be reduced if types of accident process can be estimated with a scenario, and the key points before the accident in the scenario are switched to safe points.

Even though automakers have actively been conducting studies on autonomous navigation thanks to the development and application of wireless Internet technology, the traffic accident has been kept unsolved. The causes of the accident are drowsy driving, a mistake of a driver, environmental factors, and a wrong road structure; Driving manner and characteristics of a driver among the causes are significantly influential for the accident. In this paper, a study to measure characteristics of zigzag driving that can be seen before an occurrence of an accident regarding traffic accidents that can be incurred while driving manually or autonomously was conducted. While existing studies measured zigzag driving based on characteristics of the change of lateral angular velocity by imaging techniques or driving manner on the first and second lane, this study proceeded to measure zigzag driving by setting a lateral moving distance and a critical value range by utilizing the value of a sensor.

Objective: The objective of this research is to inquire about safety information from the standpoint of its usefulness to suggest the significance of the Reactive Safety Action Program, which serves to promote aviation safety culture. Background: Safety information plays an important role in operating safety programs. Each organization learns lessons from safety information collected from aviation accidents and incidents. When an accident occurs, it is only through safety investigation and a close inquiry on the cause that we can come up with an appropriate countermeasure which would contribute to preventing the recurrence of the same or similar accident. However, the usefulness of safety information produced from unsatisfactory safety investigation is insufficient. Method: This research analyzed the characteristics of aviation accidents, the differences between safety investigations and legal accident investigations in systematic and operative perspectives, and safety culture as a measure to activate reporting systems (compulsory/voluntary). Results: This research defined the investigation scope and processes of safety investigations and legal accident investigations. It also suggested factors such as just culture based on trust, non-punitiveness, confidentiality, the participation of the entire staff through the use of inclusive reporting base, ensuring the independence of the operating organization as a way to promote safety through reporting systems. Conclusion: The organization's effort is the important aspect in obtaining exact and accurate safety information from accidents/incidents. The separate running of SIB (Safety Investigation Board) and AIB (Accident Investigation Board), the systematization of safety information reporting system, and prescribing (legislating) the composition of related organizations are some representative programs. Application: This research inquired experiences that contributed in promoting aviation safety culture in a reactive perspective, and will serve a role in spreading safety culture by enabling the use of application experiences of the aviation field in other domains.

The estimated on-site accident rate in Forestry is relatively high. According to statistics of the accident, in the recent 5 years, from 2014 to 2018, forestry accidents have resulted in 98% of injuries and 87% of fatalities. Especially, there are significant geographical constraints to access to the scene in case of an accident. Even though the capacity of first aid capacity is notably emphasized its importance to minimize the scale of damages, the relevant employees have been educated only basic first aid, which is not considered circumstances or geographic limitations, by Occupation Safety and Health Acts. Therefore, the purpose of this study is to derive a direction for a forest emergency service system to increase forestry workers' survival and prevent secondary injury through securing 'Golden Time.' This study conducts analyzing relevant laws and regulations in domestic and international settings as well as looking at several concerned accident cases. The outcome of analysis presents an issue regarding the implementation of onsite first aid in forestry and existing risk factors depending on the working process. Finally, we suggest two ways to improve the forest emergency service that are 1) an appropriate curriculum and kit for forest first aid; and 2) a system for emergency transfer through sharing information between National Fire Agency (NFA) and emergency medical service center, and emergency and rescue mission using helicopter from NFA and Korea Forest Service.
