우리나라는 도로교통사고로 인한 사회적 비용이 연간 약 15조원에 달하며 국내총생산(GDP)의 2.15%를 차지한다. 교통사고로 하루 평균 약 20명이 사망하고, 그 피해액의 규모가 약 70억원에 이른다. 구체적으로 2005년 7월에 나온 OECD 교통사고 국제비교(2003년 통계를 기준)에 따르면 우리나라는 해당 년도 1년 동안 7,212명이 교통사고로 사망했으며 이는 인구 10만명당 교통사고 사망자가 OECD 26개국 가운데 26위, 어린이 10만명당 교통사고 사망자는 25개국 가운데 25위, 노인 10만명당 교통사고 사망자는 25개국 가운데 25위 등으로 선진국의 경우와는 대조를 보이고 있다. 그동안 정부에서는 교통사고를 줄이기 위한 여러 가지 교통정책을 시행하였고 획기적인 진전이 있었으나 일반 국민들이 느끼는 교통안전에 대한 무관심은 턱없이 부족하다. 본 연구에서는 광주.전남지역에서 발생한 교통사고 현황을 전남지방경찰청의 자료를 이용하여 분석하고 적절한 교통안전대책을 제시하고자 한다.

Accident analysis is special concern to researchers in traffic safety. Accident analysis in product safety, however, is not. The needs of product safety management alter it in the world by all manufacturers. The purpose of this study is to propose a theoretical principles for product safety management through the accident cost analyses. The accident cost is a important factor to prevent product accident and to treat some claims of customers. It is sure that this principles can help all making decisions of manufactures with expected accident cost per a product accident and with total expected accident cost.

If zero-accident movement is to be successful, the objective goal period should be surely obtainable, and much more in our country where frequency rate of injury are remarkably fluc-tuating. However In our country, as far as we know, no method to establish a reasonable zero-accident goal period is guaranteed. In thls paper, a new establishing-method of reasonable goal period for individual industry with considering recent accident trend is presented. A mathematical model for industrial accidents generation was analyzed, and a stochastic process model for the accident generation inteual was formulated. This model could tell the accident generation rate in future by understanding the accident tendency through the time-series analysis and search for the distribution of numbers of accidents and accident interval. On the basis of this, the forecasting method of goal achievement probability by the size and the establishment method of reasonable goal period were developed.

This study was initiated to improve of the defect investigation method using event data recorders (EDR) and suggested a solution through the regulation and system analysis of EDR. The EDR data has been used for various purposes such as the vehicle defect investigation and the traffic accident investigation. However the EDR regulation has not been updated since the implementation in 2012. "Trigger Threshold" can be used to analyze a single accident such as the frontal crash, the side crash, and the rollover. In the case of a complex accident in which a rollover accident and a crash accident occur simultaneously, it is difficult to analyze a complex accident due to current "Trigger Threshold". This study proposed the method of separating the "Trigger Threshold" into a crash accident and a rollover accident so that accidents can be analyzed using the EDR data even when a complex accident occurs. In addition, it proposed the improvement method to quickly use the data of EDR in accident reconstruction software.

The purpose of this study is to predict how the actual accident changes by reconstructing the accident with an Autonomous Emergency Braking system (AEB) based on the actual accident of the LTAP-OD (Left Turn Crossing Path - Opponent Direction) intersection. A virtual AEB sensor was developed, and 150 head-on collision accident reports were secured to the insurance company to reconstruct the accident. As a result of the accident type analysis, a total of 13 types of head-on collision accidents were derived, and it is the LTAP-OD intersection accident with the highest frequency. In the LTAP-OD intersection accident, the simulation was conducted by applying the virtual AEB of each vehicle, the accident rate decreased by 90% or more when the AEB of the left-turn vehicle was applied, and the accident rate decreased by 50%. In addition, the most frequent collision types in LTAP-OD accidents were the front bumper on the driver's side of a vehicle going straight and the front bumper on the passenger's side of a vehicle turning left.

Severe accident analysis has been performed for the Wolsung nuclear power plants in Korea to investigate severe accident phenomena of CANDU-600 reactors as a part of Level II PSA study. The accident sequence analyzed in this paper is loss of active heat sinks(LOAH) which is caused by loss of off-site power, diesel generators, and DC power. ISAAC (Integrated Severe Accident Analysis Code)computer code developed by KAERI (Korea Atomic Energy Research Institute) was used in this analysis. This paper describes the important thermal-hydraulics and source term behaviors in the primary system and inside containment, and the failure mechanism of calandria vessel and containment. In addition, some insights for accident management program(AMP) are also given.

첨단 정보화시대에 교통사고처리 및 분석의 병행되는 업무는 개별적 수행에 따른 이중적 업무로 진행되고 있으며, 교통사고를 처리하는 현 경찰청은 최첨단 기술을 병행하지 못하고, 아직도 수작업에 의해 업무가 진행되고 있으며, 교통사고분석에 있어서는 지리요소와 개별 및 복합적 요소에 따른 교통사고 요인 대한 연구와 사고원인에 대한 사고분석에 관한 연구가 미흡한 실정이다 따라서, 교통안전정책을 효과적으로 수립 및 시행하고 이를 평가하기 위해서는 무엇보다 교통사고 자료를 토대로 교통사고 발생원인 및 특징에 대한 체계적, 과학적 분석이 선행되어야 한다. 교통사고 자료를 지형공간정보체계기반으로 구축하여 기존에 텍스트 형태의 자료 수집이 아닌 PDA를 이용하여 실시간으로 사고 자료를 표준 도로교통사고 자료 양식에 맞게 변환하여 저장 및 사고 정보를 관리할 수 있으며, 공간 데이터 특수성과 연계하여 사고원인에 대한 지리적 분석 데이터로 표출하는 통합 관리 시스템 개발에 관한 연구를 수행하였다.

As Korean government and safety-related organizations make continuous efforts to reduce the number of industrial accidents, accident rate has steadily declined since 2010, thereby recording 0.48% in 2017. However, the number of fatalities due to industrial accidents was 1,987 in 2017, which means that more efforts should be made to reduce the number of industrial accidents. As an essential activity for enhancing the system safety, accident analysis can be effectively used for reducing the number of industrial accidents. Accident analysis aims to understand the process of an accident scenario and to identify the plausible causes of the accident. Accident analysis offers useful information for developing measures for preventing the recurrence of an accident or its similar accidents. However, it seems that the current practice of accident analysis in Korean manufacturing companies takes a simplistic accident model, which is based on a linear and deterministic cause-effect relation. Considering the actual complexities underlying accidents, this would be problematic; it could be more significant in the case of human error-related accidents. Accordingly, it is necessary to use a more elaborated accident model for addressing the complexity and nature of human-error related accidents more systematically. Regarding this, HFACS(Human Factors Analysis and Classification System) can be a viable accident analysis method. It is based on the Swiss cheese model and offers a range of causal factors of a human error-related accident, some of which can be judged as the plausible causes of an accident. HFACS has been widely used in several work domains(e.g. aviation and rail industry) and can be effectively used in Korean industries. However, as HFACS was originally developed in aviation industry, the taxonomy of causal factors may not be easily applied to accidents in Korean industries, particularly manufacturing companies. In addition, the typical characteristics of Korean industries need to be reflected as well. With this issue in mind, we developed HFACS-K as a method for analyzing accidents happening in Korean industries. This paper reports the process of developing HFACS-K, the structure and contents of HFACS-K, and a case study for demonstrating its usefulness.

Low birthrate is causing a reduction in the number of students at kindergartens, elementary schools, middle schools and high schools nationwide and yet, school safety accidents are on a constant rise, which was reported to be 237 accidents a day on average in 2011. Such phenomenon is proving how the school safety policy is not doing what it was supposed to do. In order to decrease the school safety accidents, first, causes of the accidents should be analyzed and then, prevention measures should be designed. For that reason, the study looked into the present condition of the school safety accidents and safety accident theories and based on the results, "School Safety Accident Analysis Matrix Model" was proposed. With a matrix method of the accident types (17 of them) and hazard factors (9 of them) applied, the concerned model analyzed a total of 153 accident causes. In consideration of the results from the analysis, the study suggested that the education authority should open a safety organization and design a school safety policy that would systematically deal with safety education, prevention measures practice, accident investigation and analysis, and countermeasures practice as well.

The purpose of this study is to diagnose the level of disaster safety perception (disaster safety importance, accident possibility, personal safety, and regional safety) of local residents, and to analyze the impact of individual and accident cause characteristics. The analysis method used multiple regression analysis, and the main analysis results are as follows. First, disaster safety importance and accident possibility were higher as residents who had experience in safety education and were willing to visit the safety experience center in the province. Second, disaster safety importance was higher as the cause of the accident was the lack of response 119 and police. And accident possibility was higher as the cause of the accident was the lack of prior treatment by the state and local governments. Third, personal safety and regional safety were higher for men, and especially personal safety was lower as residents with children. The results of this study can be used as basic data for establishing regional customized disaster safety policies based on the perception of local residents, who are policy consumers.
