The objective of this study is to develop an evaluation model for the National highway risky areas. Thus, for the purposes of doing this, National highway risky area evaluated targeting to provide determination ranking and suggesting rival-superiority factors as well as under-inferiority factors in ten National highway risky areas. This study developed for modules of risky areas evaluation, using fuzzy set theory and analytic hierarchy process for evaluation model of National highway risky area in transport environment. The preceding studies assess risk analysis through analysis of causal relationships by National highway safety sector not only handles rating scale development suitable for assessment area by referring to accident frequency model but also geometric structures model. As result of this study, this model of Fuzzy Ahp Risk Analysis (FARA) apply for programmable design in real time processing through easily derive strategy for improvement activities to provide a decision-making effectively. Furthermore, this study contributes frame for improvements of National highway construction for renovation's priority strategy as well as future's policy schemes.

교통사고 원인분석 및 사고예방을 위해서는 교통사고 유발요인에 대한 이해가 필요하다. 기존 연구에서는 기하구조, 운전자 특성 등의 요인을 고려하여 연구를 진행하였다. 그러나, 운전자 특성요인 분석에 사용된 자료는 검지기에서 측정된 집계된 속도로써, 속도 변화량을 이용한 사고분석연구에는 한계가 존재한다. 따라서, 본 연구에서는 차량의 속도변화 등의 수집이 용이한 센서를 이용하여 자료를 수집하였다. 가속도자료 및 기하구조 특성을 나타내는 변수를 설정하고, 사고자료와 매칭을 통해 사고개연성이 높은 잠재적 변수로의 적합성을 평가하였다. T-test, 이항 로지스틱 회귀분석을 사용했으며, T-test 결과로써 도출된 변수를 이항 로지스틱 회귀분석의 독립변수에 적용하고, 사고발생 유 무를 종속변수로 설정하였다. 분석결과, 5개의 변수가 사고발생에 영향을 주는 변수로 도출되었다. 또한, 도출된 모형은 사고발생구간의 예측에 적용할 수 있는 타당성을 확보하는 것으로 분석되었다. 본 연구에서 도출된 위험 운전행태 변수 및 모형은 프로브차량에 설치하여 활용할 수 있는 장치 등에 적용시켜 사고위험도 및 안전성 평가에 활용할 수 있을 것으로 기대된다.

본 연구에서는 중저준위 방사성 폐기물 처분장의 지진위험도 평가를 위한 평가용 입력지반운동을 도출하였다. 방사성 폐기물 처분장 부지를 대상으로 한 지진재해도 평가를 수행하여 재해도 곡선을 도출하였으며 도출된 재해도 곡선을 바탕으로 등재해도 스펙트럼을 산정하였다. 등재해도 스펙트럼에 부합하는 30개의 인공지진파를 생성하여 해당 부지의 지반을 대상으로 한 부지응답해석을 수행하였다. 대상부지에 대한 부지응답해석을 통하여 지표면과 처분동굴의 상단과 하단부에서의 입력지진운동을 구하였고 각각의 평균값을 구하여 방사성 폐기물 처분장의 리스크 평가를 위한 평가용 응답스펙트럼을 제시하였다.

본 연구에서는, 반도체, LCD 공정에서 금속막을 증착하기 위하여 PECVD장비에 화재, 폭발 위험성과 독성을 가진 Silane가스를 사용하게 되는 장비인 gas cabinet, pipeline, VMB(Valve manifold box), MFC(mass flow controller)장비 등, 전반적인 시스템에 대하여 영국 HES의 ALARP개념을 도입하여 위험성 평가를 실시하여 문제점을 도출하고 대책을 강구 하는데 목적이 있고, 여러 가지 문제점중

The purpose of this study is, by recognizing that recently, as crimes using information and various adverse-effect phenomena such as hacking and virus occur frequently with rapid development of information network such as Internet in every field of industry, the range of security is widening to the field of industrial areas for preventing the leaking of industrial technology and protecting that technology as well as information security only limited to IT area, and by establishing common concept about industrial security through education on the industrial security at the point of increasing importance of industrial security, to prepare the base of comprehensive risk management system for protecting company's assets (physical factor, technical factor and managerial factor) safely from the random threats or attacks inside and outside the company through assessment of important assets of the company, evaluation of threats and weak points, and risk assessment by building industrial security management system in order to protect company's information assets and resources which are connected to the existence of the company safely from the threats or attacks from inside or outside the company and to spread stable business activities.

우리나라 연안 해역은 빈번한 선박조우로 인하여 해양사고 발생 잠재 위험이 높은 해역으로 분류되고 있으나 해상교통의 정량적인 평가의 미흡으로 맞춤형 안전대책이 제대로 수립되고 있지 않는 것이 현실이다. 본 연구에서는 울산항을 평가 대상으로 한 해상교통 안전성 평가를 실시하고, 그 결과를 실제 사고 통계 자료와 비교 하고자 한다.

In the steel industry, steel is manufactured and processed to produce a variety of steel products. The industry provides fundamental materials to the whole range of industries including car, ship, electric appliance and construction industries, so that it is very important as an infrastructure industry. The steel manufacture process involves aerial work, many danger factors caused by the treatment with hazardous gases including BFG and COG and by high pressure gases including H2, O2, N2 and LPG. It requires the management over the large area because many workers work in a plant. The potential dangers in the steel plant were identified and the effect of the danger assessment was verified through the analysis of the danger assessment for the steel plant. The allowed degree of danger was lowered after the improvement through the danger assessment in the plant where the case studies were conducted, which indicates that the danger assessment is highly effective.

Recently, in circumstantial situation it is recommended positively to utilize of EIFS(Exterior Insulating and Finishing System) as energy policy for economizing energy. But internal EPS insulators of EIFS are exterior panel of high fire risk, because of constituting of flammable materials to be fragile in fire. In this study, fire risk is assessed by experiment Con Calorimeter test and SBI(Single Burning Item) test. As the result of experiment, Con Calorimeter tests do not reach to capability standard of internal incombustible grade, and are assessed as low grade in SBI incombustible grade. Because EIPS is exterior material in buildings with high fire risk in spite of good efficiency, it is required rapidly to take measures to meet situation through various studies(for instance, adjusting law regulation, etc.) in the future.

The unsafe act and unsafe condition is due to human error that experience 80% of safety one of the most important issues to reduce industrial accidents as a whole, is how to reduce the accident rate by the human error Therefore, this paper describes the d

Steel and iron works have place many hazard or risk factor as a high temperature material, a high place, and so on. Accordingly, steel and iron works need system for risk assessment. In this paper, we development of risk assessment system for steel and iron works. In case study applied at the steel enterprise. The resultant, we can discovery that an human factor is an important question form risk assessment.

Government and company are unfolding greenhouse gas reduction activity to prevent the effects of global warming. Also, verification business through greenhouse gas inventory construction is spreaded variously. Greenhouse gas verification proceeds by document examination, risk analysis, field survey. Document investigates emission information, calculation standard, emission report, data management system. And through risk assessment result, establish field verification plan. Through study on risk assessment of greenhouse gas inventory verification, wish to reduce risk of verification.
