투자의 효율성제시가 불명확한 1단계 국가GIS사업(1995-2000)에 대한 대책으로, 최근 GIS예산 집행의 타당성에 대한 분석이 요구되고 있다. 특히 국가GIS사업의 많은 비중을 차지하는 지자제GIS사업에서 효율적인 투자는 성공적인 사업추진을 위해 매우 중요하다. 그러나 GIS투자의 타당성을 판단하기 위해서는 투자비용의 산정과 함께 그로 인한 편익 내지 효과를 측정할 수 있어야 한다. 또 측정할 수 있다면 얼마나 측정할 수 있고 얼마나 설득력있는 편익을 측정하여 정책결정이나 정치적, 재정적 지지를 얻는 데에 활용할 수 있는가가 핵심적인 주요사안으로 받아들여지고 있다. 따라서 본 연구는 지자체에서 합리적인 의사결정의 자료로 활용될 수 있도록 기존의 다양한 GIS비용효과 분석에 대한 이론적 고찰을 실시하고, 지자제GIS의 특성을 고려한 GIS비용효과분석방안을 고찰하였다. 이를 위해 지자체 GIS 발전단계에 따르는 효과 및 지자체 응용시스템별의 활용효과에 대한 국내외사례를 종합, 국내 지자체 GIS비용효과분석에 적용될 수 있는 비용과 효과의 정량적 정성적 평가항목을 구성하였다. 아울러 편익비용비, 순현재가치, 내부수익률의 평가기법에 따라 다양한 대안선정을 위한 민감도분석과 불확실성분석에 대해서도 살펴봄으로써, 지자제 GIS사업의 투자타당성확보 및 합리적인 의사결정 및 대안선택방향을 모색하였다.

In this paper, a research model is proved empirically which includes factors related on the purchase intention of smart car as high innovative product in advance of commercialization. As one of relating to consumer's expectation benefit factors, individual attribute factor includes product knowledge, individual innovativeness, and sociality. Consumer's expectation benefit factor includes perceived ease-of-use, usefulness, and enjoyment. As of switching cost variables, there are financial, uncertainty, relational and psychological switching costs factors. Analysis were performed using data from the 257 respondents as random sampling among potential consumers. Purchase intention were affected by individual innovativeness mediated by perceived enjoyment, and individual sociality by perceived ease-of-use and enjoyment also. Relational switching costs factor was only a significant control variable between purchase intention with consumer's expectation benefit factor. This result presents some implications for making the new smart car's detail concept and marketing strategy related to targeting the consumer as high innovative product and technology firms including smart car makers.

Many studies have reported additional treatment is needed to use wastewater for agricultural purpose. Economic considerations should be taken into account to establish infrastructure for agricultural reuse because of a large amount of water use in irrigation and relatively low water quality requirement. The objective of this study was to conduct economic analysis of wastewater reclamation and reuse systems for agriculture. A system dynamics approach considering complexity and dynamics in the wastewater reuse systems was used for the economic analysis, which are related with social, environmental, and economic problems. Sensitivity and benefit cost analysis for wastewater reuse systems was conducted through the established economic assessment model. The result of sensitivity analysis showed that water resources development and installation cost were the most sensitive for total benefits and costs, respectively. The scenario-based test of the organized economic assessment model shows marginal cost ranges and enables decision-makers to decide reasonable cost for the wastewater reuse systems for agriculture.

Telemedicine can increase accessibility to advance medical technology at the university hospital for community residents living in a remote area. This paper focused on the economic evaluation of telemedicine to identify important factors influencing costs and benefits and to understand how these factors can be changed to improve economic performance of the telemedicine. When the telemedicine project currently operating in Korea was evaluated based on the traditional cost-benefit analysis, the results showed a heavy net loss wiht a B/C ration of 0.56. As several values were added to the analysis based on the Information Economics approach, B/C ratios steadly increased. When the saving of medical expenses from the early detection of diseases was taken into a consideration, the ration exceeded the break-even point. >From the sensitivity analysis, a number of patients and the cost for equipment and communication were found to be the key factors for influencing economic performance of telemedicine.

An architectural means of optimal daylight distribution is by using so-called light shelf systems, horizontal shading and redirecting devices. The overall performance of the daylighting system can be improved by the incorporation with electric lighting control devices. This paper aims to exemplify the benefit of daylighting in term of economic consideration. In such a case a reasonable technique to compare system costs is by life-cycle costing. Stated simply, a life-cycle cost represents the total cost of a system over its entire life cycle, that is, the sum of first cost and all future costs. Four different electric lighting system designs are proposed and a lighting control system that is continuously operating according to the level of daylight in the space has been adapted. The result shows clearly that although denser layout of lighting fixtures might be more effective to interface to the level of daylight ceaselessly changeable, its economic benefit may not meet the expected criterion the reason of increased initial investment and maintenance cost for the fixtures and control devices.

CBAM(Cost Benefit Analysis Method)은 아키텍처 전략을 평가할 때 전략으로 인하여 얻게 될 이익(Benefit)뿐만 아니라 비용(Cost) 스케줄, 위험을 함께 고려하여 최적의 아키텍처 전략을 결정하도록 하기 위한 방법이다. 그러나 CBAM은 아키텍처 전략을 평가하는 과정이 이해당사자들의 합의나 투표, 경험적 직관에 의존하고 있어 결정에 대한 명시적인 정량적 증거를 제시하고 있지 못하다. 본 연구에서는 CBAM에서 제시한 이해당사자들의 합의나 투표를 수행하는 과정에 계층분석적 의사 결정 방법인 AHP(Analytic Hierarchy Process)를 도입하여 아키텍처 전략 결정의 증거를 명시적으로 제시할 뿐만 아니라 주관적 판단 오류의 가능성을 줄이고자 한다.

There is a rapidly growing expansion of internet-based infrastructure throughout industries in Korea. The internet-based Electronic Purchase and Supply System(EPSS) is being considered a supportive tool to increase the economic efficiency of hospital management. In this study, we conducted an economic evaluation of the system, analyzing data on four hospitals in Korea. According to the results, four hospitals was estimated to make net benefit of about 611 million Won in one year and about 2,809 million Won in the next five years. Further, the adoption of all hospitals in Korea to the system may generate net benefit of about 31,575 million Won in one year and about 166,938 million Won in the next five years. Furthermore, we expect that as the system covered many kinds of inputs in hospitals like pharmaceuticals, the benefit of the system would go up by a considerable degree.
