In recently, the Korea government is concerning on non-point source pollution management to improve water quality. The objective of this paper is to investigate the improvement measurement for management of livestock wastes. As a result, we find that the National Pollution Source Survey is necessary to establish the unified database system with the Korea Statistics(KOSAT) in order to minimize the difference between relevant data. The investigation for environmental impact of livestock manure should be supported the designation of control areas and establishment of the technical guidelines including target material, monitoring site, standard method, etc. In addition, it should be followed by appropriate nutrient recycling and proper fertilizer usage based on social consultation and cost-benefit analysis.

This paper describes the plans of considering the environmental influences in the preliminary feasibility investigation of railroad work. Because the cost-benefit analysis method about the environmental costs by air pollution and traffic noise is mainly applied in preliminary feasibility investigation, not only the verification in the calculation method of these environmental costs but also the consideration in the environmental costs of the topographical damage and the ecosystem extinction by railroad work is needed. The environment-friendly plans in choosing the locations of the railroad route and station are also suggested, and they include (1) consideration of environment protection area, residential zone, and region with scenic beauty, (2) application of the existing railroad route and station, and (3) railroad route parallel to another traffic facility.

A project of developing marine environmental risk assesment and management technology was proposed to improve the level of marine environmental management research. This paper attempts to measure the non-market benefits of the project. To this end, the dichotomous choice contingent valuation method is used. In particular, recently proposed one and one-half bounded model is applied. The model can reduce the potential for response bias comparing to the double bounded model while maintaining much of its efficiency. Moreover, in order to deal with zero WTP observations, a spike model is adjusted for our data. A survey of randomly selected 600 households was implemented and the respondents were asked in person-to-person interviews about how they would be willing to pay for implementing the project. Respondents overall accepted the contingent market and were willing to contribute a significant amount (2,663 won), on average, per household per year. The aggregate value of the project in the nation amounts to approximately 46.3 billion won per year. The figure 2.16 of cost-benefit ratio shows that economic validity of this technical development.

Environmental impact is getting more attention in many feasibility studies for railroad-related projects and research items. For sustainable growth and green transportation, the benefits typically used for feasibility studies in railway-related projects, are composed mostly of economic criterions which is not considering growing attention on changing paradigm. Based on the analysis of current methodologies, improvements in estimating environmental impact especially on noise and pollution are suggested. Active steering bogie has been proposed to satisfy stabilizing and steering performance of railroad. This paper describes the feasibility study of the active steering bogie for a urban railway vehicle based on environment-related criteria.

In order not to hinder the trend of promoting participatory forest management under the REDD-plus mechanism, we propose a simple method to support local stakeholders evaluating and selecting promising national programs as REDD-plus activities prior to the launch of activities. Program evaluation is done from the viewpoint of expectations for achieving (1) 'triple-benefit' consisting of emission reduction from mitigating deforestation and forest degradation, biodiversity conservation, and poverty alleviation, and (2) 'feasibility' when the programs would be practiced on the ground. The method is applicable for other countries.

A research on accident loss calculation for polyol process without safety management activities, and safety cost estimation using process risk assessment has been implemented. In order to estimate a magnitude of loss, accident scenarios were made by combining result made from HAZOP Study method with accident possibility analysis results implemented with FTA. Also effect assessment was implement for accident consequence of each scenario. And minimum possible loss cost has been calculated when safety investment do or not. Result from cost-benefit analysis was shown as approximately \335 billion(=USS44,000 billion), as cost after subtracting safety management cost from minimum possible loss cost.

This paper conducted an analysis of economic effects of offshore wind power in Korea with benefit/cost analysis. The existing feed-on tariff, which was too low to support wind power development, was recently replaced with a Renewable Portfolio Standard(RPS), effective from 2012. According to the new regulatory policy, The Korean government has announced a strategy to draw investments worth for offshore wind farms with a total capacity of 2.5 GW over the next eight years, which is expected the change of cost and benefit. After overview the offshore wind power development status, The effects on cost can be divided by economic, environmental and social factors. Each factor will be calculated and combined by both evaluating index and using Quantification methods. At the end, the implication for the evaluation of feasibility of offshore wind power of Korea will be done.

The private investment on the SOC facilities is a worldwide tendency since it can supplement the insufficient investment of public finance in the construction of infrastructures. Alter the formulation of private investment law, private sector's investment on roads, harbors and environmental facilities are being progressed considerably. However, railway construction by private sector is not active comparing to the former areas because of huge investment for construction but relatively low and unpredictable benefit in operation. This paper reviews the financial, social and institutional aspects on the private investment for SOC projects, especially railway projects. Also, this paper tries to find the desirable way to expedite the private investment on railway project,. Conclusively, the paper propose that the private sector in railway projects is better constituted with financial investor and the private financing could be. activated and settled if a stable minimum benefit on their investment being ensured institutionally, for example, by BTL.

High speed and large transfer capability of railroad has been an important issue in Korean since KTX opening at 2004. Improvement projects for railway electrification are progressed in the conventional line as well as high speed line because various operation plan is performed such as interaction between high speed line and conventional line and operation of tilting train etc. Especially, railway electrification has many advantages which are cost effective and eco-friendly. But it also has some problems such as construction costs and accidents due to electrification. Therefore this paper developed measuring index of electrification railway benefit. By comparing between diesel and electrical locomotive, the operations of before and after the electrification and measurements quantitative index such as energy efficiency, enlargement of transfer capability, environmental pollution and maintenance and efficiency of operation is presented. In the future, Overall benefit and cost of railway electrification will be analyzed.

At this point that port industry brings a new change as the concept of 'Green Logistics' appears, studies on an economic analysis of existing port Re-modeling have normally been conducted focused on market value factors such as Benefit-Cost analysis, On the other hand, there have been few studies on the analysis of Non-market value factors such as environmental value. Therefore, the purpose of this study is aimed to establish a Feasibility analysis model of Incheon inner port Re-modeling in the aspect of Non-market Benefit Factors classified by related factors such as, marine environment, waterfront facility and welfare of users by using AHP methodology based on the extracted result through previous studies.
