This study estimated indirect economic benefits of the introduction of Korean Spatial Information System. Korean academic society has been reluctant to consider indirect benefits as an item of benefits in cost-benefit analysis. Nevertheless, other countries including England recommend to consider some indirect benefits like option value as an important item of cost-benefit analysis, especially in the case of transportation projects. This study estimated indirect benefits of the introduction of Korean Spatial Information System using Contingent Valuation Methods: Indirect benefits of the project are so significant in terms of statistics and substantial in terms of magnitude that decision making can differ from the case without consideration of such indirect benefits.

홍수피해경감편익 가운데 직접편익 항목은 크게 일반자산피해액, 인적피해액, 공공시설물피해액으로 구분되며, 이 가운데 공공시설물피해액은 현재까지 국내실정을 고려하지 않은 일본수치를 그대로 차용하여 실제 적용시 해당지역의 규모, 특성을 무시한 채 평가되어 왔다. 이러한 공공시설물 홍수피해액은 전체 피해액에서 차지하는 비율이 상대적으로 매우 크고, 해당지역의 개발정도에 따라 피해정도가 상이할 수 있기 때문에, 이에 대한 보다 실증적이고 합리적인 접근이 필요하다. 그리하여 본 연구에서는 국내 실정에 적합하고 지역특성을 실제적으로 고려한 공공시설물피해액을 산정하기 위한 방안을 모색하였다. 이를 위해 본 연구에서 고려하는 공공시설물을 재정의하였고, 피해특성 및 양상에 따라 침수심 예민 공공시설물과 침수심 비예민 공공시설물로 분류하여 각각에 대한 분석절차를 제시하였다.

This study aims to analyze the freight transport demand and benefit for the introduction of an automated freight transport system focusing on the Global Industry and Logistics City (GILC) in Busan. In pursuit of this aim, four alternatives were calculated - using the freight volume estimating methods and included, the number of businesses, the number of employees set up, future estimated cargo volume, and switched volume from other transport modes into the GILC. Economic benefits were analyzed against social benefits and costs accordingly. The result of the freight transport demand forecast found, the cargo volume of "Alternative 2-1" to be the most advantageous, applying the number of employee unit method and proportion of employees in Gangseo-gu, Busan. In addition to the conventional analysis of direct benefit items (reduction of transport time, traffic accidents and environmental costs), this study also considered additional benefit items (congestion costs savings, and road maintenance costs in terms of opportunity cost). It also considered advanced value for money research in guidance on rail appraisal of U.K, Federal Transport Infrastructure Plan 2003 of Germany, and RailDec of the United States. The study aims to further contribute to estimating minimum cargo transport demands and assess the economic feasibility of the introduction of new intermodal automated freight transport systems in the future.

`Information measure model' and 'Information benefit model' for road plan are developed. In result of application to actual road project, 'Information measure model' showed same result with actual road plan, it can express qualitative element by 'Information' like safety, public discontent, etc. and 'Information benefit model' can evaluate present plan in the side of provider's and demader's 'benefit'.

This study utilizes the meta-analysis for the benefits transfer (MA-BT) approach to measure social costs the 7 target sites in the City and County of Honolulu. The estimated MA models (MA-1 and MA-1) were evaluated in terms of validity and reliability criteria. This study utilized a parametric t-test and a non-parametric sign rank test for checking validity. A transfer error measured by an absolute percentage difference was utilized to check reliability their similarity. The GIS was utilized for data collection in order to measure social costs for each target site. The results clearly demonstrated that social costs were substantially higher thant direct costs and varied market conditions and different methods used. In terms of validity and reliability criteria, MA models were preferred to the mean transfer value approach. MA-BT approach is desirable for measuring social costs for a project designed to measure social costs for these 7 proposed landfill sites with inaccessible data, on short time frames, and with little money. If researchers and planners have enough time and money, they can implement primary research. If not, the meta-analysis for the benefits transfer approach can be much better than no framework. The use of a GIS can help to identify secondary data within a specific radius of each target site.

This study quantitatively derived the direct socio-economic effects of the Gyeongbu Expressway, which opened in 1970, and suggested a methodological approach for more reliable results. The scenario was set when the Gyeongbu Expressway was not constructed in 1970, the opening of the Gyeongbu Expressway was delayed by 10 years, and the toll road between Seoul and Daejeon, or between Seoul and Gangneung was opened instead of the Gyeongbu Expressway as suggested by the World Bank. In addition, direct benefits were estimated by calculating and comparing the current vehicle operating costs, travel time costs, traffic accident costs, and environmental pollution costs. As a result, it was estimated that about 351 trillion won in direct benefits occurred, and it can be seen that the promotion of the construction project of the Gyeongbu Expressway at that time had a huge impact on South Korea's social economy.

The purpose of this study is to investigate the retention and caries prevention practical effectiveness of fissure sealant and regular checkup with cost-benefit analysis. The data of this study is based on "2000 The Survey of Korean Oral Health" by Ministry of Health & Welfare. This study is to investigate cost-benefit analysis on proper treatment for the decayed, in case of operating fissure sealant on molars at 1 year after eruption of permanent teeth. The obtained results were as follows: (1) Cost-benefit analysis on fissure sealant in 6-75 year old 43,736 thousand Korean people reveals that cost of fissure sealant is 1,610,994 million won and benefit is 69,460,691 million won. (2) Benefit of fissure sealant is 39.51 times as much as cost of fissure sealant. (3) Cost of twice in a year regular checkup is 2,678,544 million won. Indirect cost of regular checkup is 2.6 times as much as direct cost. (4) Cost of fissure sealant and twice in a year regular checkup is 4,289,538 million won, and benefit is 69,460,691 million won. Benefit of fissure sealant and twice in a year regular checkup is 16.2 times as much as cost.

The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal diseases. The paper is to estimate the direct effects of economic benefits on aquatic animal disease prevention program using economic surplus analysis. The economic benefits include changes in consumer and producer surplus owing to a reduction effect of aquatic animal mortality and the consumption recovery effect. The annual changes in producer surplus for flounder, rockfish and others cultured is estimated as 2.33 billion won totally (0.87 billion won, 1.01 billion won and 0.45 billion won respectively) and the annual changes in consumer surplus 10.15 billion won totally (6.36 billion won, 1.85 billion won and 1.94 billion won respectively). Therefore, total annual economic benefit is 12.5 billion won.

각종 오염물질이 수계로 유입되어 침강하면 하상에 퇴적되는데 이 오염된 퇴적물 중 질퍽한 콜로이드상의 물질을 오니토라 일컫는다. 이 오염물은 저장소 및 물환경의 변화에 따라 수질 악화의 직접적인 원인이 될 수 있는 인, 질소 등의 영양염류를 수중으로 재용출시킬 수 있는 비점오염원 종류 중 하나이다. 하천 준설은 하천에서 저수용량 확보와 하상 유지관리 및 골재확보, 수질 개선을 위해 토사를 제거하고 그 토사를 운반선에 의하여 운반하여 지정된 투기장에 투기하는 일련의 공사를 말하며, 이를 통하여 비점오염원인 오니토를 직접적으로 제거할 수 있다. 준설의 필요성 판단 및 수질개선 효과를 모니터하기 위해서는 하천의 수질과 유량을 조사해야 한다. 이때 대상구간이 요구하는 수질 기준에 부합하지 않으면 오염퇴적물 준설 기준을 통해 준설이 필요한 구간 및 사업량을 결정한다. 준설 사업량의 경제적 타당성을 정량적으로 검증하기 위해 대상 구간을 준설을 하지 않을 시 오니토가 상시 용출된다는 가정하에 물재생시설로 이 오염물을 정화했을 때의 비용을 준설 사업비와 비교하였다. 본 연구에서는 하천공사 표준시방서(2007)에 제시된 오염퇴적물 준설 기준을 만족하는 서낙동강수계의 준설 계획 지구에 대한 계획 사업비와 해당 지구 하류에 위치한 물재생시설의 정화능력 및 운영비를 비교해 하천 준설 사업비에 대한 편익을 산정하였다.

농업부문이 사회에 제공하는 다양한 긍정적 외부효과가 인정됨에 따라, 대부분의 농업생산기반시설은 국부를 증진시키는 사회간접자본으로 인식되고 있다. 과거에는 수리시설을 비롯한 기반시설이 단지 생산성 향상을 위한 사회적 투자로 간주되었으며 따라서 사업에 대한 경제성 분석 또한 직접적인 경제적 효과에 대한 편익비용분석에 국한되었다. 그러나 최근에는 농업 및 생산기반시설이 제공하는 비시장적 가치가 점차 인정됨에 따라 그러한 가치 또한 경제성분석에 포함될 수 있다
