Human health risk assessment for petroleum, oil and lubricant (POL) contaminated sites is challenging as total petroleum hydrocarbon (TPH) is not a single compound but rather a mixture of numerous substances. To address this concern, several TPH fractionation approaches have been proposed and used as an effective management tool for the POL-contaminated sites in many countries. In Korea, there are also recognized needs to establish a reliable and cost-effective human health risk assessment strategy based on the TPH fractionation method. In order to satisfy the social and institutional demand, this study suggested that the comprehensive risk assessment strategy based on a newly modified TPH fractionation method with 10 fractions, the Korean Standard Test Method (KSTM)-based analytical protocol and a stepwise risk assessment framework should be introduced into the domestic contaminated land management system. Under the proposed strategy, POL-contaminated sites can be effectively managed in terms of human health protection, and remedial cost and time can be determined reasonably. In addition, more researches required to increase our understanding of environmental risks and improve the domestic management system were proposed.

Value at Risk(VaR) has been proven useful in finance literature as a tool of risk management(cf. Jorion(2001)). This article is concerned with introducing VaR to various Korean financial time series. Five daily data sets with sample period ranging from 2000 and 2004 such as KOSPI, KOSPI 200, KOSDAQ, KOSDAQ 50 and won-dollar exchange rate are analyzed using GARCH modeling and in turn VaR is obtained for each data.

This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.

본 연구는 비행청소년을 대상으로 재비행위험성 정도에 가장 영향을 미치는 요인은 무엇인지 알아보고, 이 요인들을 설명하는 심리적인 특성을 찾아보고자 하였다. 피험자는 서울시 ${\bigcirc}{\bigcirc}$경찰청에서 비행행동으로 비행행동촉발 조사서와 PAI 검사를 받은 268명이었으며, 남자 220명, 여자 48명이었다. 비행 촉발요인에 대한 재비행 위험성 집단간 차이는 가족구조를 제외한 5가지 요인, 즉 가족기능, 학교생활, 가출경험, 비행전력, 개인경험에서 차이가 있었다. 재비행 위험성 집단 간 PAI 검사 결과는 신체호소, 우울, 망상, 정신분열, 경계선, 반사회성, 음주문제, 약물사용의 임상척도와 공격성, 자살관념, 스트레스 비지지의 치료고려 척도, 그리고 지배성과 온정정의 대인관계 척도에서 집단간 차이가 있었다. 비행촉발요인과의 PAI 척도의 관련성에서는 대부분의 척도에서 유의미한 상관이 있었으며, 특히 우울은 모든 비행촉발요인과 상관이 나타났다. 비행촉발 요인 중 가족구조에 대한 설명력은 스트레스와 온정성이, 가족기능에서는 비지지와 음주문제가, 학교생활에서는 음주문제와 우울이, 가출경험에서는 음주문제와 스트레스가, 비행전력에 대해서는 음주문제가, 그리고 개인경험에 대해서는 음주문제와 지배성, 경계선이 설명력을 가졌다. 전체적으로 보면, 재비행위험성 정도에 따라, 음주문제, 우울, 그리고 대인관계관련 척도가 비행촉발요인을 설명하였다. 비행의 원인으로 다양한 입장들이 있고, 개입요인들도 그에 따라 달라지지만, 비행청소년의 심리적인 측면에 대한 개입을 통해 비행행동의 재발을 예방하는 데 효과가 있을 것으로 사료된다.

Background: Decision making modalities for screening for many cancer conditions and different stages have become increasingly complex. Computer-based risk assessment systems facilitate scheduling and decision making and support the delivery of cancer screening services. The aim of this article was to survey electronic risk assessment system as an appropriate tool for the prevention of cancer. Materials and Methods: A qualitative design was used involving 21 face-to-face interviews. Interviewing involved asking questions and getting answers from exclusive managers of cancer screening. Of the participants 6 were female and 15 were male, and ages ranged from 32 to 78 years. The study was based on a grounded theory approach and the tool was a semi-structured interview. Results: Researchers studied 5 dimensions, comprising electronic guideline standards of colorectal cancer screening, work flow of clinical and genetic activities, pathways of colorectal cancer screening and functionality of computer based guidelines and barriers. Electronic guideline standards of colorectal cancer screening were described in the s3 categories of content standard, telecommunications and technical standards and nomenclature and classification standards. According to the participations' views, workflow and genetic pathways of colorectal cancer screening were identified. Conclusions: The study demonstrated an effective role of computer-guided consultation for screening management. Electronic based systems facilitate real-time decision making during a clinical interaction. Electronic pathways have been applied for clinical and genetic decision support, workflow management, update recommendation and resource estimates. A suitable technical and clinical infrastructure is an integral part of clinical practice guidline of screening. As a conclusion, it is recommended to consider the necessity of architecture assessment and also integration standards.

This paper is a comparative study on risk assessment policy between Asian countries such as Japan, Korea, Singapore and EU countries, German, UK. Risk assessment is a tool adopted currently in many countries in order to reduce occupational risk in workplace because it help employers to identify their hazard arousing in their working conditions then to settle the issues. This paper compares institutional framework posed in EU and Asian countries. As a result of comparative study, EU countries have more concrete legal system for risk assessment than Asian countries. But Asian countries are now interested in risk assessment such as Japan, Korea and Singapore. The author also suggests successful ways to settle down the risk assessment policy in a country. These findings help to understand occupational health and safety policy on risk assessment in Asian countries.

Technology innovation companies are focusing on contributing to business performance by R&D project as a strategic tool. Successful R&D leads to corporate competitiveness enhancement, national industrial development, but there are high uncertainty and risks in R&D. Public and private R&D projects are carried out to achieve various purposes. It was verified how the risk management and benefit management of the R&D project affect the detailed R&D project performance between the Public and private domain. The impact of Project Leadership on R&D performance was also analyzed. Those who have participated in the Public and Private R&D projects at companies or research institutes were surveyed. First, it was found that project risk and benefit management have partially an effect on R&D project performance. Second, Public and private R&D Project Leadership showed partially a interaction effect between project management and project performance.

최근 활발히 진행되고 있는 도시재생사업과 같은 대규모 복합개발사업은 사업기간이 길고 다양한 사업주체들이 참여한다. 이러한 특성 때문에 사업추진 과정상 많은 위험요인들을 내포하게 되고 이를 관리하는 것은 사업의 성패에 큰 영향을 미친다. 그러므로 도시재생사업에서 위험을 인지하고 대응하는 일련의 위험관리 과정은 정확하고 체계적으로 수행되어야 한다. 위험관리과정에서 위험인지단계는 다양한 위험요인을 인지하고 그 위험의 성격을 규정하는 첫 단계이다. 위험을 인지하는 기법 중 체크리스트는 가장 보편적이고 실용적인 방법이라고 할 수 있다. 따라서 본 연구에서는 도시재생사업의 개발단계에서 사업주체들의 업무를 분석하고, 위험을 도출하여 사업주체별로 위험을 분류하는 체크리스트를 제안하였다. 이러한 주체별 위험요인 체크리스트는 실무자가 쉽게 위험을 파악할 수 있는 도구로써, 도시재생사업과 같이 다양한 사업주체들이 자신은 물론 다른 사업 참여자들의 위험을 인지하는데도 효과적일 것이라고 기대된다.

건설공사의 성공적인 수행을 위한 다양한 건설관리기법들 중 리스크관리기법은 프로젝트 규모의 대형화, 신공법 적용 등에 의한 불확실한 요인의 증가에 의해 그 중요성이 부각되고 있다. 따라서 본 연구에서는 현장실무자들의 공정리스크 관리 업무를 지원하기 위해 공종별 공사프로세스 중심의 공정리스크 확인방법과 현장별 특성이 반영된 공정리스크 중요도 지수를 개발하였으며, 향후 타 현장에서의 적용을 고려한 공정 리스크 중요도 보정방법을 제안하였다. 또한 공정리스크 요인별 대응방안을 현장에서 공사일정에 따라 검색하고, 공정정보와 연계된 공정리스크 관리 업무의 출력기능을 갖춘 공정 리스크 관리지원 시스템 프로토타입을 개발하였다. 공정리스크 관리지원 시스템은 건설현장 실무자들이 공정리스크 관리업무를 수행하는 데 필요한 지식을 제공하여, 의사결정지연에 따른 공기 지연을 방지할 수 있을 것으로 기대된다.
