This study analyzed the direct costs of fall accidents, which have the highest accident rate, for domestic construction industry workers. Firstly, the average insurance payment per person due to fall accidents in the construction industry is around 19 million won (18,971,000 won). Given that the average number of workers suffering fall accidents over ten years is 5,863, the total cost of losses from fall accidents is about 1.1 trillion won (111,360,000,000 won). Secondly, a cost-based economic feasibility analysis was done to develop nonstructural preventive measures for fall accidents. Since there was no data expressing the costs and effects of preventive measures in terms of monetary value, the economic feasibility analysis was attempted with a focus on how much the newly introduced preventive measures can reduce the accident loss costs due to fall accidents. Thirdly, if the accident loss size is grasped and the preventive measures for the causes of fall accidents are developed and strictly implemented, the insurance fee that can reduce the accident loss costs can be determined. Further study is needed to estimate the benefit of the accident loss cost reduction seen from the cost-based approach method.

Following the accident at Fukushima, the true impact of multi-unit accidents came to light. Accordingly, research related to multi-unit accident effect analysis, risk evaluation, and accident prevention/prevention technology has been conducted. Specific examples are mobile/fixed equipment such as multi-barrier accident coping strategy (MACST) and diverse and flexible coping strategies (FLEX), which have been introduced and installed in multi-units for preventing and mitigating multi-unit accidents. These strategies are useful for enhancing the safety of nuclear power plants (NPPs); however, a more efficient strategy is required in terms of the costs of physical and human resources. To effectively and efficiently mitigate an increase in multi-unit accidents, it is necessary to not only to utilize mobile/fixed equipment but to also use crosstie options with resources that already exist at NPPs. Therefore, we analyzed the current international and domestic status of crosstie systems technology and propose a method to evaluate feasibility alongside risk based on a multi-unit probabilistic safety assessment (PSA). To analyze the international and domestic status of crosstie systems technology, actual cases and related research were studied, and a list of potential crosstie safety resources was derived. Additionally, a case study was performed on crosstie cases of two systems within the assumed six units on-site under a multi-unit accident, and a multi-unit PSA-based risk evaluation method is proposed.

Although Korea coastal area has the increasing potential marine accident due to frequent ship's encounter, increased vessel traffic and large vessel, there is no specific model to evaluate the navigating vessel's risk considering the domestic traffic situation. The maritime transport environmental assessment is necessary due to the amended maritime traffic law. However, marine safety diagnosis is now carried out by foreign model. In this paper, therefore, we suggest a domestic traffic model reflecting the characteristics of korea coastal area and navigator's risk as we named PARK(Potential Assessment of Risk) model. We can evaluate the subjective risk by establishing the model and model output into maritime risk exposure system. To evaluate this model's effectiveness, we used ship handling simulation and applied, analyzed collision accident which occurred in korea coastal area. And also, we applied integrated to an ECDIS program for monitoring traffic risk of vessels with real time based AIS data and apply to evaluate traffic risk in busan harbor waterway. As a result, we could evaluate busan harbor waterway risk effectively.

This study statistically analyzed the laboratory accidents by investigating 806 laboratory accident survey reports which were officially submitted to government from 2013 to June 2017. After comparing domestic and foreign accident classification criteria, the laboratory accidents were classified using KCD7(Korean Standard Classification of Diseases) and OIICS(Occupational Injury and Illness Classification System) criteria. For the type and part of injury, KCD7 classification criteria was adopted. And, for the cause and occurrence type of accidents, OIICS was adopted to analyze the laboratory accidents. Most of injuries happened to the wrist and hand caused by sharp materials or chemical materials. The analysis of accident cause showed that accidents resulted in medical practice and accidents from handtools and chemical materials such as acid and alkali frequently occurred. The major occurrence types of laboratory accidents was body exposure to the chemical materials such as hydrochloric acid and sulfuric acid. In addition, the accidents resulted in destroy of grasped object or falling object were frequently reported.

Recently, the construction industry is increasingly in need of securing safety rights due to repeated serious accident. Accordingly, the government enacted the "Serious accident Punishment Act" to strengthen punishment for serious accident and expand the scope of punishment. However, safety managers in the construction industry are still vulnerable to safety accidents due to the heavy workload. The purpose of this study is to increase the efficiency of performance tasks and reduce serious accidents in the construction industry through analysis of performance tasks by stages of construction projects. The tasks derived through domestic research and domestic and foreign system analysis were classified step by step to analyze the correlation between difficulty and preventive effect, and inefficient tasks were discovered and improved. This can be used as basic data for identifying safety management tasks and preparing effective safety prevention measures, and it is expected to be a preventive measure against industrial accidents in the construction industry by using it for efficient work reorganization by safety managers.

Since a few years ago, great disasters have often took place in domestic and abroad, such as Sampoong Department store collapse, Sea-land disaster accident, Incheon Hof fire accidents. Whenever a lot of accidents occurred such as fire, gas explosion, traffic accident, mountain accident, various disease, people required 119 first aid service. As the result, even for the last year, average 2,608 person per day were temporary treated and carried to near hospital by 119 system. But first-aid team or first grade EMT(emergency medical technician) that should provide high quality service and save important lives, might have negatively treated or made their duty only for simple transfer, when they were imminent of emergency case in every kinds of accident spot. Because they worried about medical dispute for "task restriction for EMT" decided by medical laws or rules of first aid. So it was proposed that "task restriction for EMT" should be mitigated or released in the possible range on this occasion.
