This paper measures welfare losses from beef consumption reduction, which might be resulted from psychological anxiety about potential outbreak of BSE (commonly known as "bad cow dieses") risks after announcement of resuming US-beef imports in April of 2008. Unlike the previous literature of utilizing the contingent valuation method or experimental market approach, this study estimated quality-differentiated consumer demand functions using the information of self-reported beef consumption quantity, individually constructed price indices of beef, and subjective perception of BSE risks. The empirical results based on a survey sample of 360 residents in Jeon Ju city were consistent with the anticipation from economic theory, in terms of coefficients of own prices, substitute prices and income variables. The announcement of resuming US-beef imports did not make significant differences in the sign and sizes of the main economic variables. However, the subjective perception variable about BSE risks had negative significant impacts on beef demand functions after the announcement but not significant before the announcement. The welfare losses in a form of equivalent variation (EV) corresponding to the increases in concerns about BSE risks were measured to be about 30 thousand won per household.

최근 국내 보험시장은 개방화, 국제화 등으로 기업의 위험관리에 대한 인식의 변화가 일어나 위험관리 업무의 수요가 증가하고, 손해보험회사에서도 고객에게 질 높은 서비스를 제공할 수 있도록 위험관리의 선진화를 위해 다각적인 방안을 모색 중에 있다. 이러한 분위기 속에서 동부화재 위험관리연구소는 장기적인 안목을 가지고 재물보험 분야뿐만 아니라 산종위험에 대한 연구 및 방재기술 개발 등 R&D 업무 강화를 통해 독자적인 업무 분야를 개척하여 향후 위험관리 분야의 선두조직으로 우뚝 서고자 노력하고 있다.

A university needs to analyze and improve its curricula with the perspective of the consumer to develop a syllabus for the training of industry-demand customized human resources. Accordingly, this paper surveyed the demand of fire-related industry workers to evaluate the major fitness of the curriculum of fire risk prediction and assessment and carried out descriptive statistical analysis, factor analysis, cluster analysis, and one-way ANOVA based on the results. According to the analysis, fire-related industry workers reported that the curriculum of fire risk prediction and assessment is suitable for majors. In addition, they were greatly aware of the necessity of basic major and common major subjects among subjects of fire risk prediction and assessment. The results of this analysis will provide the basic data to improve the curriculum continuously in the future.

The purpose of this paper is to examine how demand for labor affects the job seeker's decision on the level of investment in education. In the current paradigm of economic growth in which innovations and technological developments generally weaken the strength demand for labor and increases the uncertainty related to employment, this paper provides a theoretical framework that can be used as a basic framework in understanding the decision of investment in education in varying conditions of demand for labor. The following are the findings of this paper. First, the level of investment in education can generally be regarded to be higher as the demand for labor exacerbates but for the job seekers with a certain characteristic. Second, the Arrow-Pratt absolute risk-aversion measure is the characteristic of the job seeker that determines in what direction the job seeker changes in the level of investment in education, For an arbitrary level of demand for labor there exists a certain threshold which determines the minimum degree of risk-aversion required for the job seeker's Arrow-Pratt should go over to increase the level of education as demand for labor weakens. Third, the job seekers lower the level of education even though the demand condition in labor markets weakens if the compensation function does not depend on the level of education. This is surprising because it turns out that one of the reasons why job seekers invest in education is that they want to be recognized in their compensation for their level of education even when more education still raises the probability of employment.

에너지 소비를 줄이기 위해서 세금을 올리자고 한다. 세금이 오르면 가격이 오르고 높은 가격은 소비를 위축시킨다. 하지만 세금으로 수요를 조절하려는 방안은 아주 위험 할 수도 있다.

시험평가는 무기체계를 획득하는 과정에서 의사결정자에게 필요한 정보를 제공하여 획득과 관련된 위험요소를 식별하여 위험을 감소시키거나 제거하는 위험관리 도구로써의 역할뿐만 아니라 소요군인 수요자에게 무기체계에 대한 신뢰성을 보증하는 역할을 하기 때문에 이의 중요성을 아무리 강조하여도 지나침이 없다. 시험평가 개혁은 획득비용 절감, 획득기간 단축, 무기체계의 신뢰성 제고 등 획득개혁의 핵심요소인 바, 시험평가의 개혁이 곧 획득개혁을 보장할 수 있다.

This paper proposes a way to a risk quantification of public sector comparator in the value-for-money test of the BTL (Build-Transfer-Lease) scheme in rail investment projects. Two principal risks that are project delay and budget increasing costs are identified and are empirically quantified with a case study of the Haman-Jinju link. The methodology suggested is expected to be a good reference for the similar research afterwards and also to help in settling down the scheme that is only an early stage.

국가단위로 구축예정인 신규 IT인프라의 계획 및 설계 단계에서 신규 IT인프라에 잠재하는 위험도를 사전에 종합적으로 분석하기 위하여 현재까지는 위험분석 이론이 사용되고 있으나 여러 가지 적용상 한계점이 지적되고 있다. 본 연구는 이와 관련하여 신규 IT인프라의 위험도를 일정 단위의 등급으로 분류하여 정부기관, 서비스 제공자, 서비스 수요자가 정확하게 인지하고 대응할 수 있도록 하기 위하여 신규 IT인프라에 대한 위험수준 등급화 모델의 필요성을 제시하는 것이 목적이다.

In this study, a model of compensation and amendment of forecasted travel demand was developed to calculate the range of values depends on the changes in the risk factors, selecting factors that might affect traffic demand changes among risk factors. Selected factors are as follows: influenced area population, the number of registrated vehicle per person, ratio of service industry workers, and city intervals. Then this model is applied to six routes of expressway and the calculated value were compensated with error rate being reflected on each quartile value with respect to influenced area population (200,000 people standards). Result from appling developed model to Cheongwon-Sangju expressway suggests that the model could compensate the error rate by more than 50%, which in turn validate the effectiveness of the model developed. Some limitations and future research agenda have also been identified.

공업과는 달리 농업부문은 생산성향상을 위해 막대한 투자와 장구한 시간을 필요로 한다. 따라서 생산성향상을 위한 여건조성의 시간적 여유를 주지않고 생산성이 낮으니 수입을 자유화해 외국산 농축산물로 수요를 충당하는 것은 매우 위험스러운 접근이다.
