그동안 다양한 도로설계 안전성 평가 연구는 교통사고다발지역인 교차로에 집중되어 왔다. 또한 도로구간에서는 특정한 기하구조 요인이 교통사고율에 어떠한 영향을 미치는지에 대한 연구는 일부 수행되었으나, 도로구간에서의 안전성 평가를 위한 다양한 원인분석을 위한 연구는 여전히 미진한 실정이다. 따라서, 본 연구는 지방부 도로구간에서의 안전성 평가를 위해 도로구간을 지방부 2차로 도로와 다차로 도로구간으로 구분하여 통계적 기법을 적용하였다. 일반적으로 도로구간에서의 교통사고는 "0"의 빈도가 높게 나타나므로 통계적 분석 시에 이를 고려해야만 한다. 따라서 본 연구에서는 사고의 비선형적 요소를 설명하는 허들모형이 전통적인 포아송 및 음이항모형보다 도로구간에서의 발생하는 교통사고의 성격을 설명하는데 더욱 적절한 것으로 판단하여 분석을 시작하였다. 본 연구에서는 지방부 도로구간에서의 사고빈도 예측모형 개발 및 도로구간 안전성 평가를 위해서 지방부 2차로 도로구간과 다차로 도로구간으로 구분하였으며, 모델분석결과 교통사고를 유발시키는 변수가 각각의 유형에 따라 서로 다른 것으로 분석되었다.

Objectives: This study described the features of home-bound industrial accident victims and their needs for rehabilitation services. This study was also aimed to find a future direction of development of community rehabilitation programs that are suitable for their needs demands. Methods: This study is a descriptive study, were collected through two phases using structured questionnaire. In the first stage, su were performed via telephone interviews. In the se stage, surveys were performed via home visit Subjects in the first stage included 2203 indu injured victims staying at home, of whom. individuals complaining of post-traumatic complic became the subjects of the second stage. Results: This study showed that the home-bound industrial accident patients were complaining of complications from the injury even after receiving treatment by IACI. However, they were neglecting their health problems without any intervention. Even if they use health care services. the treatment is mainly focused on acute medical care, which may not effective for them. Furthermore, they had unstable employment status and suffered from financial burden for health care costs. The Labor Welfare Organization has established a plan to remove barriers of industrial accident victims in reinstatement, and has been preparing various programs in order to establish an all-embracing service system for industrial accident victims from accident occurrence to reinstatement. However, these rehabilitation services can be truly helpful only when the injured are able to obtain enough information about them. The current restrictive system is also not appropriate for solving health problems of the industrial accident victims. Therefore, it is necessary to develop a plan that can provide industrial accident victims high-quality rehabilitation services so that they can use those services in the community without being dependent on hospitals. This study proposes visit nursing services as a way to provide various health services within community for the industrial accident victims.

Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.

Accident rate in domestic construction industry has been increased rapidly in every year. In particular, the rate of death has been shown very high compared with other industries. It means that safety activities performed by government is not effective in reducing the rate of accident. To solve these problems, the risk factors should be predicted in advance, controlled, monitored and managed from start of project to end of project. However, most studies have been conducted by using frequency of occurrence of accident and only listed the importance of risk. Therefore, the objective of this study is to provide basic material to develop risk quantifying model for human accidents on construction site in South Korea. In the future, it is expected to be used as a reference of study on developing safety mangement checklist in construction industry and model for forecasting accident.

A total loss of all heat sinks is considered a severe accident with a low probability of occurrence. Following a total loss of all heat sinks, the degasser/condenser relief valves (DCRV) become the sole means available for the depressurization of the primary heat transport system. If a nuclear power plant has a total loss of heat sinks accident, high-temperature steam and differential pressure between the primary heat transport system (PHTS) and the steam generator (SG) secondary side can cause a SG tube creep rupture. To protect the PHTS during a total loss of all heat sinks accident, a sufficient depressurization capability of the degasser/condenser relief valve and the SG tube integrity is very important. Therefore, an accurate estimation of the discharge through these valves is necessary to assess the impact of the PHTS overprotection and the SG tube integrity of the primary circuit. This paper describes the analysis of DCRV discharge capacity and the SG tube integrity under a total loss of all heat sink using the CATHENA code. It was found that the DCRV's discharge capacity is enough to protect the overpressure in the PHTS, and the SG tube integrity is maintained in a total loss of all heat accident.

Simple statistical frequency based analysis, such as Pareto analysis, are widely used in conventional accident analysis. However, due to the dynamic and complex nature of construction works, many factors can simultaneously affect or involve the occurrence of accidents in construction projects. Therefore, the identification of the complex relationship between such factors is important to establish relevant and effective safety management policies and/or programs. In this study, characteristic factors and their relationships' contribution to non-fatal accidents in construction projects are analyzed using the association rule mining (ARM) technique. To this end, a total of 59,202 construction accident data are collected from 2015 to 2019 and the ARM is performed to retrieve specific relationships -named as association rules-among classified factors in the data. Characteristics of the retrieved relationships are analyzed and compared with the results of conventional Pareto analysis. Based on the results, it is found that both fall and trip are notable accident forms having characteristic relations with other factors for non-fatal accidents in construction projects. It is also found that small-scale construction, age of 50s, less than 1 month of working period, and architectural construction are important factors for non-fatal accidents in construction projects.

Recently, occurrence of alcohol-involved traffic accidents is increasing while all the accidents by violation of law except drunk driving. Traffic accidents by drunk driving has a great external cost. In detecting drunk driving, blood alcohol content Many studies reported close correlation between blood alcohol content and traffic accidents by drunk driving. The risk of traffic accidnet increases exponentially as blood alcohol content increases. To control traffic accidents by drunk driving, decide target population. Heavy drinkers are few and responsible for a small part of the loss while casual drinkers are many and responsible for a large part of the loss. Casual drinkers need to be included in the targer population for the control of traffic accident by drunk driving. Stragegies to reduce the quantity of alcohol consumed, change the pattern of drink, such as frequency of drinking, raise of perceived risk of accident need to be sought.
