The Korean government is considering the implementation of the marine debris pollution abatement technology program (MDPATP) to mitigate the negative impacts of marine debris and systematically manage marine debris through scientific researches such as monitoring and environmental impact assessment of marine debris. In this regard, this study attempts to analyze the economic feasibility of the MDPATP in order to provide policy-maker with useful information. To this end, the indices for economic feasibility such as net present value (NPV), benefit/cost (B/C) ratio, and internal rate of return (IRR) are presented. The results show that NPV, B/C ratio, and IRR are computed to be 45.7 billion won, 2.72, and 17.12%, respectively, which are bigger than 0, 1.0, and 5.5%, and that the MDPATP passes the cost-benefit analysis. Thus, it is concluded that it is socially profitable to conduct the MDPATP.

Background: This study aims to analyze the behavioral changes of healthcare providers and influencing factors after the reviewer unification of auto insurance medical benefit claims by an independent review agency. Methods: The comparison data were collected from the second half of 2013 and the same period of 2014. The key indicators are the number of admission days, the number of outpatient visits, inpatient ratio, inpatient medical expenses, and outpatient medical expenses. Results: Four indicators (number of admission days, number of outpatient visits, inpatient ratio, and outpatient medical expenses) showed statistically significant drops, while one indicator (inpatient medical expenses) showed no significant change. Conclusion: The reviewer unification of auto insurance medical benefit claims by an independent review agency showed significant reduction in cost and patient days.

The project of promoting the economy has attracted attention as on strategy for the economic revitalization of abandoned mine areas which is promoting by local government based on the "Special law on the development of abandoned mine areas". Through the analysis of economic feasibility analysis, the government is trying to determine the presence or absence of budget support to project of promoting the economy of local government. Furthermore, this paper attempts to conduct a cost-benefit analysis, using net present value(NPV), benefit/cost(B/C) ratio, internal rate of return(IRR) techniques for project of promoting the economy of Samcheok City. The project of promoting the economic of Samcheok City is promoting the Yukbaeksan flowers rest park and Glass Art Culture and Tourism theme park. The results indicate that NPV, B/C ratio and IRR of Yukbaeksan flowers rest park are 3,937 million won, 1.06, 6.18% and NPV, B/C ratio and IRR of Glass Art Culture and Tourism theme park are 8,311 million won, 1.34 and 9.47. Accordingly, the projects of promoting the economic of Samcheok City ensure economic feasibility that the three indicators have exceeded 0, 1.0 and 5.5% respectively. Moreover, the analysis results can be used effectively in the decision for the project of promoting ecomony of Samcheok city.

In order to improve the quality assurance of the disaster mitigation projects, the economic effect of these projects in the hazardous areas was analysed. Eight project sites were selected for analyses based on the disaster data during the previous 10 years, and the investment effect was evaluated using a benefit cost ratio (B/C). The benefit was estimated using the historical disaster data and presumed to continue for 30 years, while the cost was assumed with the total project cost. Analysis results indicate the B/C ratio is larger than 1 in the difference range, depending on factors such as impact areas and discount rates. According to the analysis results, the average B/C of the eight projects is 4.1 with assuming the discount rate of 4% and the impact diameter of 5 km, which implies that a disaster management project in hazardous areas will give the positive investment effects.

To promote the consistent and effective implementation of IMO instruments such as SOLAS, MARPOL, STCW, LL, TONNAGE, COLREG IMO has adopted voluntary IMO member state audit. This audit scheme is voluntary audit which will be carried out on a voluntary basis, at the request cf the member state to be audited. Nevertheless, the Korea government is preparing the implementation of the audit scheme to strengthen the competitiveness in shipping and shipbuilding industries. In this paper, we investigated the actual conditions of implementation of mandatory IMO instruments and carried out a feasibility study by assessing the cost to be audited and positive effects expected by introducing the audit scheme. As a result of cost benefit analysis we obtained high benefit-cost ratio.

The main purpose of this research is to analyze economic feasibility of biodegradable sonw crab gill net model project. The results of benefit/cost analysis show that use of the biodegradable gear is economically feasible. Assuming that the rate of gill net lost is 5 percent, net present value was estimated 311,898,282-590,533,375won, benefit-cost ratio 1.816-1.923 and internal rate of return 7.96-10.59%. The development and diffusion of biodegradable fishing gear appear to make a significant contribution to fisheries resource conservation and marine ecosystem protection. In addition, biodegradable gear production firms may have a good opportunity of exporting it to other coastal states, depending on the progress of WTO subsidy negotiation.

The optimal reservoir storage capacity is needed to be determined at the stage of reservoir planning. The reservoir storage capacity should be based on water balance between demand and supply, and meet the water deficity during the growing season. However, the optimal reservoir storage capacity should be determined considering benefit-cost analysis for the project. In this study, Two models are developed. The one is the RSOM(Reservoir Storage Optimization Model), that is consisted by three submodels, MROPER (Modified Reservoir OPERation model), RESICO(REservoir SIze and the construction COst computation) model. And the other is the BECA(BEnefit-Cost Anaysis) model. For model application, three districts, Chungha, Ipsil and Edong were selected. The relative difference of B/C ratio between project planning data and estimation by RSOM is 17.9, 15.0 and 7.3% respectively, which may be applicable for water resources development feasibility planning.

The purpose of this study is to estimate the economic value and productivity achieved through a reduction in fishing vessels engaged in coastal and offshore fisheries. We found that the value of increasing catch by types in offshore and coastal fisheries was about 17,338 billion won. To examine the economic value, a cost-benefit analysis was applied. This is based on the total cost of vessel reduction (4,576 billion won) assumed to be invested equally each year for five years. BCR and NPV with a discount rate (5.5%) were used to compare the profit of fishery activities in offshore and coastal areas. The model results showed that the NPV and BCR in offshore and coastal fisheries was 5,522 billion won and 2.340 respectively.

Purpose: Neonatal screening tests are increasingly being used forearly diagnosis of inborn errors of metabolism (IEM) in the hope of avoiding the severe developmental delay, acute illness, and death that may result from these diseases. In this study, a cost-benefit analysis was performed on the neonatal screening of maple syrup urine disease, homocystinuria, galactosemia, and congenital adrenal hyperplasia in Korea. Materials and Methods: This study included 1,259,220 Korean newborns born between January 2005 to December 2007, who were screened for maple syrup urine disease, homocystinuria, galactosemia, and congenital adrenal hyperplasia. We calculated and compared the total costs in cases where these four screening tests were implemented, and those where they were not. Results: There were no benefits to screening for maple syrup urine disease or homocystinuria due to their low prevalence for these two tests, the costs exceeded the benefits at benefit:cost ratios of 0.5:1 and 0.6:1, respectively. In contrast, benefits far exceed costs at a ratio of 4.1:1 for galactosemia and 2.9:1 for congenital adrenal hyperplasia. The average benefit:cost ratio for all four tests was 2.0:1. Conclusion: Neonatal screening tests for maple syrup urine disease, homocystinuria, galactosemia, and congenital adrenal hyperplasia are financially viable.
