This study has performed comparative analysis on benefit indicators in agricultural irrigation and drainage project cases between Korea and Japan. The irrigation and drainage project with publicity should do economic analysis of direct benefit factors as well as indirect benefit factors. However, traditional economic evaluations are used that benefit factors are lack of consistency and focused on direct benefits. Therefore, the purpose of this study was to develop indicators for the economic evaluation of irrigation and drainage projects. We conducted a case study between Korea and Japan. The resulting benefit factors was divided into direct factors and indirect factors. The direct benefit factors were increase in income, cost savings. The indirect benefit factors were protection of property due to flooding, agricultural promotion, aesthetic improvement. The implications of this study are that the indicators of economic analysis can be evaluated and easily applied. Moreover, these indicators could promote the feasibility of economic analysis.

The introduction of a ubiquitous environment has realized commercial ubiquitous services in various industrial fields and government area. The central and/or local governments are demanding an appropriate investment evaluation model for ubiquitous service. Thus, this study develops and suggests an evaluation model for ubiquitous service by reflecting its characteristic of promoting public good, as well as its broad ripple effect on people. The investment evaluation model for ubiquitous service suggested by this study is based on Cost Benefit Analysis Method. Especially, the 'Benefit' is analyzed in two aspects; 'Economic Benefit', which shows the benefit that ubiquitous service providers to the overall local economy, and; 'Financial Benefit', which shows the profit of individual investors participating in the introduction of ubiquitous service. The investment evaluation model for ubiquitous service suggested by this study can be used by the central and/or local government during their evaluation for investment before introducing a ubiquitous service. Also, when introducing a ubiquitous service in public field, the model can be used to support the decision making of private businesses for investment. Finally, it can be used to promote and inform the expected benefits of introducing a ubiquitous service to local residents.

Purpose: Cost-benefit analysis is one of the most commonly used economic evaluation methods, which helps to inform the economic value of a program to decision makers. However, the selection of a correct benefit estimation method remains critical for accurate cost-benefit analysis. This paper compared benefit estimations among three different benefit estimation models. Methods: Data from community-based chronic hypertension management programs in a city in South Korea were used. Three different benefit estimation methods were compared. The first was a standard deterministic estimation model; second, a repeated-measures deterministic estimation model; and third, a transitional probability estimation model. Results: The estimated net benefit of the three different methods were $1,273.01, $-3,749.42, and $-5,122.55 respectively. Conclusion: The transitional probability estimation model showed the most correct and realistic benefit estimation, as it traced possible paths of changing status between time points and it accounted for both positive and negative benefits.

In this paper, we reviewed the evaluation methodologies of railway project considering the benefit incidence. Generally railway projects are much more reduced tile energy consumption, traffic accident and environmental pollution than road projects. But conventional B/C analysis of railway project does not measured including those benefits. Also there is a few attention to an incidence of benefits producing from railway construction. So we developed the evaluation method of railway project contained the railway oriented benefits and also considered of the benefit incidence producing from railway construction.

The basis of the economic evaluation of vaccination is the balance between the use of the resources (input) and the improvements that result from the vaccination (output). Techniques used for economic evaluation of vaccination are cost analysis, cost-minimization analysis, cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis. Cost analysis seeks to characterize the costs of a given vaccination program. Cost-effective analysis is to helps policy-makers decide on the best use of allocated resources, whether cost-benefit analysis is to helps policy-makers decide on the overall allocation of resources. Cost-utility analysis is a specific form of cost-effective analysis in which outcomes are reduced to a common denominator such as the quality-adjusted life year (QALY) or disability-adjusted life year (DALY). Many economic analyses have been conducted on vaccines in the world, but there have been a little studies on economic evaluation on vaccines in Korea. This paper reviewed the methodology used to economic evaluation on vaccines and immunizations and addressed some examples of the methods.

What benefit items from railroad investment are evaluated, and how those items are quantified have profound impacts on the feasibility of the proposed investments. They also have implications on the projects priorities, not to mention on intermodal comparison between highway and railroad. Evaluation procedures currently being utilized in Korea show limits in fully evaluating railroads' investment impacts. Economic and practical implications are evaluated for including revenues for railroad investment. Based on the critical evaluation of procedures in other countries, and based on the analysis of Korea's national transportation goals, new and improved benefit items are redefined and quantification guidelines are proposed.

Purpose: The objective of this study is to verify the economic validation of quality management integrated train freight car by analyzing economic evaluation indicators such as benefit and cost, net present value, and inter rate of return. Methods: First, we itemize benefit and cost field by reviewing literatures; Benefit consists of 1)Safety, 2)Operation, and 3)Maintenance; Cost consists of 1)Set-up fee, 2)Wireless internet fee, and 3)Cloud storage using fee. Second, based on these estimated values, we conduct an economic evaluation analysis. Among them, benefit and cost, net present value, and internal rate of return are selected. Results: As a result, all estimated values are highly over criterion of economic validity($$B/C{\geq}_-1$$, $$NPV{\geq}_-0$$, $$IRR{\geq}_-R$$); 1)benefit over cost ratio is 28.22, 2)Net present value is 8,121.66million KRW, and 3)Internal rate of return value is 2272%. Conclusion: The findings of this study will help making a decision when train industry adopts IoT technology for improving the effectiveness.

교통시설 건설사업을 기획하고 평가하는 단계에서 형평성 및 효율성에 많은 논란이 제기되고 있는 사업들이 존재하고 있다. 그 이유 중의 하나는, 사업의 타당성을 평가함에 있어서 소요되는 비용은 명백히 드러나지만 사업실시에 따른 편익항목의 종류와 기준은 애매모호한 부분이 존재하기 때문이다. 이에 본 연구에서는 편익항목을 설정하는 기준을 명확히 하기 위하여 우선적으로, 부산광역시의 도로 및 도시철도의 시설이용자에 대한 만족도 평가와 함께 교통시설에 있어 기존의 경제성 분석방법으로 평가를 실시하였다. 그 결과 이용자들은 도시철도 이용에 대한 만족감이 도로이용보다는 높게 나타났으나 경제성 분석 방법인 B/C분석을 행한 결과, 도시철도시설이 대상도로에 비해 경제적 타당성이 상당히 낮은 것으로 나타났다. 이와 같은 모순적인 사실은 현재 부산광역시의 인구에 대비한 지하철 수단분담율에 비춰볼 때 편익항목에 대한 설정 기준이 맞지 않아 편익의 값이 다소 적게 산출된 결과라고 판단할 수 있다. 따라서 본 연구에서는 교통시설 건설타당성 평가를 실시할 경우에 고려되어야 할 편익항목들을 열거하고 ANP기법을 통하여 각각의 항목에 대한 가중치를 산정하였다. 그 결과 접근성, 정시성, 주행시간 순으로 높은 가중치를 가지고 있었으며, 기존의 경제성 분석시 고려되는 편익항목보다는 주민의 교통여건향상에 따른 편익항목이 더욱 높은 중요도를 가지고 있는 것을 알 수 있었다.

The objective of public works planning is being converted from economic growth to sustainable development. So, the demand for considering social & ecological influences as well as economic components had been increased in evaluation of public works planning. In evaluation of public works, its components related with benefit and cost in feasibility analysis can be classified to qualitative and qualitative elements. Qualitative elements are evaluated by qualitative methods which can manage various items, be commonly applied nationwide, and consider elements that can be calculated numerically such as environments, willingness, etc. In this study, using the concept of 'Information measure', a method to design planning of rural works is proposed. 'Information benefit model' for rural works can evaluate present plan in the side of provider's and demander's 'benefit'. And, optimizing method of rural works by 'Information benefit' can simulate present state and optimize the site and route of rural works.

Recent heavy rains and typhoons broke down road slopes, which caused a hazard to safety. As a result, interests in the effective investment for disaster prevention is increasing. Measures of investigation method for slope have been taken, but the financial costs have never been analysed. This study applied the cost-benefit analysis theory used in public economics to the evaluation of the financial reasonability of management for slope. By applying cost-benefit analysis to road slope investigation method, the reduction of safety costs and resulting financial benefits can be seen and it also clarifies the reasonability and investment effects of slope management.
