This study attempts to assess the effect of the 1st class health insurance program to the income redistribution among the participants in a unit health insurance cooperative. One health insurance cooperative, located in Seoul, with 1558 members and 768 households was selected for this purpose. The relationships between amount of premium payed and benefits from the cooperative were compared. Necessary data were obtained from the bills submitted to the health insurance cooperative by the contracted medical institutions from 1st January 1977 to 30th June 1979. Households and individuals were the unit of the assessment. The indicators measuring income redistribution effect were the ratios between the benefit and expected benefit and the ratios between the benefit and the mean benefit. The major findings were: 1. The ratios between the benefits and the expected benefits were lower than 1 in the high income group and greater than 1 in the middle and lower income groups. This fact imply that the income redistribution effect was shown in the studied groups. It was shown that the middle income group received the greatest benefit, and then the lower income group. 2. The ratios between the benefit ana the mean benefit of the households in the higher standard income grade, were found to be higher. This means that the equity of the benefits of households were not achieved by the policy of the health insurance plan. 3. The health insurance utilization rates of the higher standard income group, measured by the household unit, were higher, and by the individual unit, the same rates of the middle income group were higher than other groups.

After electricity power industry restructuring, "Long term power development plan", setting up by government, is replaced by "Basic plan of electricity supply and demand". In this basic plan, one of the most important factors is assessment of appropriate capacity margin. The benefit of GENCO is decided by the market price, and the price is largely affected by the level of reserve margin. As a consequence, appropriate reserve margin is determined by market power. However, Cost Based Pool(CBP) is a limited competitive market, and government policy for supply and demand is very important factor or reserve margin determination. This paper points out issues about existing reserve margin assessment method which is used in basic plan and suggests improved assessment method. In the case study, capacity margin is calculated by proposed assessment method and result shows the advantages of suggested method.

For the prevention of marine accidents based on human factor, the risk assessment analysis procedure is proposed which consists of (1) the structural analysis of marine accident, (2) the estimation of incidence probability based on the Fault Tree analysis, (3) the prediction of ef-fectiveness to reduced the accident risk by suitable countermeasures in the specified functional system, and (4) the risk assessment by means of minimizing of the total cost expectation and the background risk. As a practical example, the risk assessment analysis for preventing is investigated using the proposed method.

According to the growing concerns of the public with efficiency and effects of regional policies, their assessment works have become an important issue. Up to now, several studies have been carried out on economic effects of policies using conventional cost/benefit analysis, while there have been few studies on assessment of amenity oriented policies. From the above consideration, this study tried to develop An Annual Expenditure Assessment Model (AEAM) for amenity-oriented policy-making in rural area. As a pre-work for model development, the hierarchical indices system for rural development and the classification system of expenditure were designed. Being based on high significant relationship between rural amenities and local government expenditure, a linear optimization model for maximization of regional amenity was constructed. Through a case study of Sunchang-gun, Chonbuk-province, the model applicability was ascertained.

The objective of this paper is to propose a method of how to perform risk assessment in the early stage of defense research and development for the acquisition of weapon systems. An advanced method for risk assessment and its associated objective functions are developed first based on the concept of systems engineering. The developed method is then applied to carry out the analysis of alternatives in the trade-off environments. As a case study, the multi-purpose training ship is considered, where it is performed using the notions of technology readiness levels, degrees of difficulty, and technology need values to facilitate design space visualization and decision maker interaction. It is noted that decision makers can benefit from our approach as an improved risk assessment method in the context of multi-criteria decision making.

Traditionally, road projects are initiated based on an assessment of their economic benefit, after which the environmental, social and governance effects are addressed discretely for the project according to a set of predetermined alternatives. Sustainable road infrastructure planning is vital as issues like diminishing access to road construction supplies, water scarcity, Greenhouse Gas emissions, road-related fatalities and congestion pricing etc., have imposed severe economic, social, and environmental damages to the society. In the process of addressing these sustainability factors in the operational phase of the project, the dynamics of these factors are generally ignored. This paper argues that effective delivery of sustainable roads should consider such dynamics and highlights how different aspects of sustainability have the potential to affect project sustainability. The paper initially presents the different sustainability-assessment tools that have been developed to determine the sustainability performance of road projects and discuss the inability of these tools to model the interrelationships among sustainability-related factors. The paper then argues the need for a new assessment framework that facilitates modelling these dynamics at the macro-level (system level) and helping policymakers for sustainable infrastructure planning through evaluating regulatory policies.

Nuclear cardiac imaging has been widely used to assess viable myocardium in patients with ischemic heart disease, The assessment of viable myocardium is important in selecting patients who will be benefit from revascularization. Although revascularization is indicated in patients with sufficient myocardium, patients with scar tissue should be treated medically. Nuclear imaging methods including myocardial perfusion SPECT and FDG PET have been shown to be effective modalities for identifying viable myocardium.

시장 환경 변화가 심한 상황에서 정보화로 기대되는 효과가 기업의 성과에 직결되지 않는 한 적극적인 IT 투자는 기대하기 어렵다. 경영자의 IT투자 의사결정을 유도하기 위해서는 IT투자의 사전평가를 통해 그 투자의 타당성을 입증하는 것이 중요하다. 본 논문은 IT 투자와 그 투자에서 얻어지는 효과를 사전에 분석하여 투자타당성을 평가할 수 있는 방법론을 제시한다. 이 방법론은 IT 소유비용을 체계적으로 분석해서 가시적 인 비용뿐만 아니라 숨겨진 비용도 파악한다. 또한 IT투자로 인한 재무적인 효과와 비재무적인 효과를 화폐가치화 하여 IT ROI를 산출한다. 본 논문은 IT 투자의 객관적인 투자 타당성을 평가하여 IT 투자 의사결정을 지원하고 효율적 인 IT 투자가 이루어질 수 있는 체 계를 제시한다.

현재의 경제성 평가는 교통량이 적어 편익이 적은 경우나 산악지형과 같이 터널 및 교량이 많은 도로와 같이 건설비가 많이 소요되는 사업의 경우, 기존의 비용편익분석으로는 타당성이 낮게 평가되는 경향이 있다. 그러나 이러한 사업도 생활환경의 개선, 방재기능의 강화, 격지지역의 민생안정, 양호한 경관 형성 등의 효과를 고려하면, 이들 사업은 타당한 사업으로 평가 될 수 있다. 본 논문에서는 현재 경제성 분석에서 계량화하여 반영하지 못하고 있는 도로사업으로 인하여 발생 가능한 파급효과에 대해 화폐가치화하기 위한 방법론 및 절차를 제시하고 실제 도로 건설사업을 대상으로 분석을 수행하였다.
