The object of this study is to develop a tool for quantifying risks related to the rail transportation of hazardous commodities and to present mitigation measures. In this study, the Quantitative Risk Assessment (QRA) is used as a risk analysis tool. Based on the previous explosion history (Iri explosion) and consideration of its high risk, Iksan-si is selected as a model city. The result, expressed as average individual risk for exposed people with various distance, indicates that the model city is considered to be safe according to the nuclear energy standard. Also, the mitigation measures are provided since Societal risk of Iksan-si is set within ALARP. Risk reduction measures include rail car design, rail transportation operation, demage spread control as well as derail prevention and alternative routes for reducing accident frequencies. Finally, it is expected to achieve high level of public safety by appling the risk reduction measures.

Recently, various accidents caused by reagents in laboratories have demanded a safety management system suitable for the danger situation. The existing system operated the equipment according to the temperature and humidity change inside the reagent cabinet, but the operation of the device corresponding to the danger situation and the countermeasures against many dangerous situations are insufficient. In order to solve this problem, this paper proposes a reagent cabinet safety management system based on the reagent cabinet danger priority in happen of accidents caused by reagents under management. The danger priority is type of reagents and selected by the danger situation that can be caused by the reagents. If a danger situation occurs, operate the device according to the selected danger priority and the type of danger situation. It is considered that the reagent cabinet can be safely managed by checking the danger situation in the reagent cabinet and operating the device according to the danger priority.

Recently, the damage caused by natural disasters such as typhoons and localized torrential rains has been increasing rapidly. The Ministry of the Interior and Safety enacted a ｢law on safety management of small sized infrastructures｣ and local governments have to register small sized infrastructures with the National Disaster and Safety Management System (NDMS) until March 31st every year. Recently, each local government has ordered Safety inspections of small sized infrastructures and maintenance plans and six types of facilities, including small streams, small bridges, farm roads, access roads to village, inlet weirs, and drop structures are being surveyed and digitized into a database. Each facility is being evaluated for risk, and for those deemed hazardous, maintenance plans are being developed. However, since the risk assessment method of small sized infrastructures is not clear so that is conducted through visual investigation by field investigators, risk assessment is conducted in a subjective and ambiguous form. Therefore, this study presented a reasonable and quantitative risk assessment method by providing a quantitative evaluation indicator for small stream, which has the highest disaster risk among other small sized infrastructures, so that small sized hazard infrastructures can be selected to secure transparent evidence for improvement plans and action plans.

The gas production plants supply the inert gas to production plants for maintaining safe operation and also supply combustible, flammable, explosive and toxic gases as functions of basic materials needed for producing chemical goods. In addition, gas plants need to be safe and reliable operation because they are operated under high temperature, high pressure, cryogenic and catalytic reactions. As these plants have a complex process in operation, there has been a risk that major industrial accidents such as a fire, explosion and toxic gas released, also risks of asphyxiations by inert gases and burns caused by high temperature and cryogenic substances. This study is to carry out the semi quantitative risk assesment method which is the generic risk analysis (GRA). This method is applied to air separation unit(ASU) to identify its initial risk, safety barriers, residual risk and elements important for safety(EIS). The result of this study, suggested the management tools and procedures of implementation for EIS management.

This study focuses on drivers' risk perception & construct in risk scene. The measures used were the scores of hazard perception, namely the subjects' evaluation of the degree of risk through the 'Q-sorting' with 30 drivers. The subjects were divided into 3 groups according to their evaluating score, Z-score, road users' hazard(type 1), environmental hazard(type 2), situational hazard(type 3). And ten constructs derived from Q-sorting were compared through 'consensus item analysis'. It suggest that there are different in constructs for risk perception. Then those results are discussed in terms of theoretical and practical implication of traffic safety including accidents analysis and drivers' education.

Based on major safety-related statistics of cities, provinces, counties, and districts across the country, social disasters manage regional safety index ratings in six areas(traffic accidents, fires, crime, life safety, suicide, and infectious diseases), and natural disasters operate a management system. The current application of the regional safety assessment of natural disasters is very insufficient to evaluate the local risk of natural disasters up to the Eup, Myeon, and Dong level, and it is marked too engineering and difficult for the general public to use. The purpose of this study is to present Korea's natural disaster local risk assessment as an improvement model that extends to the sub-unit of Eup, Myeon, and Dong, using the local risk assessment model mixed with natural and social disasters.

습도가 안전의 요소로서 비중이 증가하고 습도의 이상검출을 필요로 하는 위험물의 저장, 식품, 섬유, 전자 등의 산업이 발달함에 따라 인간의 안락함과 정상상태의 습도를 안전하게 유지하고 이상발생에 대해 검출할 수 있는 환경적인 안전에 사용될 수 있는 습도센서의 연구가 진행되고 있으며 습도센서의 영역에서 결로센서의 중요성은 금수성 위험 물질의 저장 및 관리, 화학 plant 공정제어 등 안전분야에서 필수적으로 요구되고 있다. (중략)

실 상황하에서 안전에 대한 훈련이나 시뮬레이션은 매우 위험한 결과를 초래할 수 있으므로 효과적인 훈련을 하기가 어렵다. 그러나 가상현실 기술을 이용하여 몰입감 있는 가상환경을 구축하여 활용하면 참여자가 위험에 직접 노출되지 않고 안전에 대한 훈련을 받을 수 있으며, 여러 시나리오에 대한 시뮬레이션을 할 수 있다. 이러한 이유로 가상현실의 안전분야에 대한 응용은 급속도로 확대될 것으로 사료된다. 본 연구에서는 가상현실의 안전분야 응용에 대한 범주를 제시하고, 응급상황의 발생 시에 이를 효율적으로 관리할 수 있는 가상환경을 구축하기 위한 개발단계를 제시한다.

가을철은 기온이 선선해지면서 사람들의 활동량이 늘어나는 계절이다. 어린이들도 학교나 가정 등, 실내외 활동이 왕성해지면서 각종 안전사고에 노출되기 쉬워진다. 특히 어린이들은 주변 사물에 대한 호기심이 크고 활동량이 많은 특징을 가지고 있으나 주의력과 판단력 등 인지능력이 아직 성숙하지 못한 까닭에 위험에 대처하는 능력이 미숙하다. 띠라서 상시 안전사고 예방교육을 통해 어린이들에게 위험요소들에 대한 주의와 대처 능력을 키워주어야 한다. 어린이들의 활동량이 늘어나는 계절 10월, 이번호에서는 어린이 안전사고 예방 교육의 중요성과 각종 안전사고 사례, 예방과 응급처치 등에 대한 특집을 마련한다.
