The feasibility study is an evaluation and analysis of the potential of a proposed project. It is based on extensive investigation and research to support the process of decision making. A systematic approach to determining the optimum use of scarce resources, involving comparison of two or more alternatives in achieving a specific objective under the given assumptions and constraints. Economic analysis takes into account the opportunity costs of resources employed and attempts to measure in monetary terms the private and social costs and benefits of a project to the community or economy. Cost-benefit analysis (CBA), sometimes called benefit-cost analysis (BCA), is a systematic approach to estimating the strengths and weaknesses of alternatives that satisfy transactions, activities or functional requirements for a business. It is a technique that is used to determine options that provide the best approach for the adoption and practice in terms of benefits in labor, time and cost savings etc. The CBA is also defined as a systematic process for calculating and comparing benefits and costs of a project, decision or government policy and projects.

Biodiversity is defined as totality of genetic, species, and ecosystem variability. It provides natural sources of crop improvement, traditional medicine and biotechnology. In 1993, the Convention on Biological Diversity(CBD) became a legally binding framework for conserving and utilizing global biological diversity. It recognizes national sovereign rights over all genetic resources, such as the need to compensate developing countries for the resources they have provided to the industrialized world. The CBD grants access to those resources in exchange for compensation as well as technology transfer, so that the access to genetic resources would be made under prior informed consent(PIC) and mutually agreed terms(MAT). On the other hand, the developed countries argued that unfettered exchange of genetic resources was essential for scientific research and development, and that technology using genetic resources should be protected. There are many countries today, developing legal frameworks concerned with access to their local genetic resources and benefit sharing. In this study, we analyzed the international trends for conservation of biodiversity and sustainable use of genetic resources, and suggested how to cope actively with the situation.

Korea government promote renewable energy as the core of their energy matrix to break the dependence and reduce greenhouse effects. This study analyzes the economic assessment of Solid Refuse Fuel project in urban area, considering the marginal external costs of air pollution in this area. Assessment index defined as costs (i.e., construction cost, operation cost) and benefit (margin, external cost) data which is located in Sudokwon landfill site. The result indicates that cost-benefit analysis of SRF is calculated as 1.0. In addition, SRF project is very sensitive about electric power selling price, operating cost and labor cost according to inflation rates. This study shows that the sustainability of SRF project is required the government financial support like investment funds as well as policy support. Variability analysis of SRF economic assessment due to renewable energy can be used for making policies in various fields such as waste and public energy field.

The Korean market of pension plans has recently increased and pension plans will be expected to play an important role in the retirement system as complement of the national pension system in the future. However, there are a few of research papers on actuarial projections of pension plans. This paper will discuss a long-term financial projection on defined pension plans using data based on the national pension workplace participants. Previous researches focused on company-based financial projection of pension plan. But, this paper concerns on total Korean pension participants and suggests a method to calculate future financial projection of total pension plans. Finally, this research will suggest several numerical results of normal costs, benefits, numbers of workers, etc.

When a trade conflict arises related to an officially supported export credit programme, The World Trade Organization(WTO), decides on whether the programme is a forbidden subsidy stipulated in the Agreement on Subsidies and Countervailing Measures(the ASCM Agreement). Korea was taken to the WTO panel two times for the export credit programme. One is the semiconductor case in 2002 and the other was the shipbuilding disputes in 2004. And, In 2012, the U.S. Commerce Department ruled K-SURE's export insurance for Korean refrigerator manufacturers as a forbidden subsidy even if the case was not taken to the WTO. This paper examines the significance of export credit programmes on the WTO ASCM Agreement and discusses how to operate these programmes so they would not infringe upon the Agreement by analyzing the actual cases of WTO subsidy conflicts that involved Korean enterprises in relation to export credit programmes for the purpose of determining the related issues and impacts. From this research the results were as follows: First, on whether export credit is a prohibited subsidy, the deciding factor was whether a benefit has been conferred to the beneficiary. On the presence of a benefit, the WTO panel used market benchmarks as the main criteria. Thus, official export credit agencies(ECAs) should be careful not to provide export credit support which had been granted to the beneficiary at better than market terms. Second, in the case of export credit, the special status of ECA as a public body receiving government support itself does not constitute a subsidy. However, caution must be taken not to provide export credit that may lead to WTO ASCM subsidy conflicts involving a certain exporter or industry by setting up clear and valid regulations and fair work processes in the operation of export credit programmes. Third, item (j) of Annex I cannot be interpreted reversely as this item is for interpreting the presence of a prohibited subsidy, not the presence of a benefit. Thus, an export credit program that confers a financial contribution, a benefit and specificity, could qualify as a prohibited subsidy. Fourth, ECAs not only have to maintain long-term account balance but also introduce additional measures to meet this long-term balance such as a clear and systematic premium system. Finally, export credit programmes that are not defined in item (j) of Annex I of the ASCM Agreement would not deemed as an prohibited export subsidy as long as the continued support of the programmes are not being forced.

This study was carried out to measure atmospheric environmental improvement effect and estimate its social benefit of thermal power plants through Environmental Impact Assessment (EIA) for quantitative analysis about operational performances of EIA. In this study, 'EIA outcome' is defined as whether or not the system is implemented, therefore, environmental standard to be followed by each project and consultation contents were compared. In total 60 cases of thermal power plant construction projects that have been consulted over the past 10 years since 2010, major air pollutants have been significantly reduced after the implementation of EIA. The $PM_{10}$ reduced annual 3,745 tons, $NO_2$ by 74,569 tons, and $SO_2$ by 37,647 tons, which were estimated at approximately 240 billion won~5 trillion 967 billion won per year for social benefit. This means the total cost of power plant operations will be cut to 7 trillion 192 billion won~178 trillion 994 billion won over a 30-year period. The reduced amount of air pollutants emitted by energy generation facilities across the country is worth 50%, and its economic value is larger than the annual Current Health Expenditure in Korea. This is meant by the fact that all projects are subject to uniform criteria under the existing relevant regulation, but that each project plans are optimized according to the characteristics of target areas and projects through the process of EIA.

The purpose of our this research, based on the Media Selection Theory, the Technology Acceptance Model, and the Social Influence Theory, is to investigate the influential factors that affect media selection in banking transactions. Analyses showed that for location sensitive bank window's and ATMs (automatic teller machines), defined as offline-based transaction channels, convenience was the variable affecting media selection. However, in the case of online media not related to location, (phone banking, internet banking, and mobile banking) reliability was the significant variable influencing use. The findings show that banking organizations may benefit from identifying traits of media affecting use, and should differentiate customer services for competitive advantage.

The reinforcement of the token, which is based on the token economy currently applied in blockchain-based cryptography, plays a critical role in forming the cryptographic-related ecosystem. Therefore, in this paper, it was investigated the reinforcement principle of token supporting the Token economy for blockchain model. In order to create a healthy ecosystem based on the reinforcement system principle, it is necessary to find ways to secure scalability by seeking consensus between the participants and the market economy structure so that it can generate an influx of more participants than seeking to maximize profits of certain people. Desirable behavior is defined as an action required by ecosystem participants that have the property of making the token ecosystem sustainable, and to do so, each individual receives appropriate incentives (rewards) when taking this action, ultimately encouraging voluntary participation and action by all participants in the ecosystem to optimize the interests of both individuals and participants. The expected benefit of this study may contribute to the establishment of various business models based on the principle of the reinforcement system.

This paper suggests generalize mathematica mode for the benefit of volumetric error analysis of a multi-axis machine tool machining a sculptured surfaces. The volumetric error, in this paper, is defined as a three dimensional error at the cutting point, which is caused by the geometric errors and the kinematic errors of each axis and alignment errors of the cutting tool. The actual cutting position is analyzed based on the form shaping model including a geometric error of the moving carriage, where a form shaping model is derived from the homogeneous transformation matrix. Then the volumetric error is obtained by calculating the position difference between the actual cutting position and the ideal one calculated from a Nonuniform Rational B-Spline named as NURES. The simulation study shows the effectiveness for predicting the behavior of machining error and for the method of error compensation.

The term "Strategic Alliance" which is not exactly defined in legal sector can apply to a wide variety of collaborative activities between firms, In spite of the vague conception Strategic Alliance, it has many benefit in the market. Especially, cooperation in R&D may reduce duplicative and unnecessary costs, lead to significant exchange of ideas and experience and thus result in products and technologies being developed more rapidly than would otherwise be the case. As a general rule, R&D cooperation tends to increase overall R&D activities. However, R&D agreements may cause competition problems such as restrictives effects on prices, output, innovation and variety or quality of products, To prevent its problems, competition authorities set out guidelines. The antitrust analysis of strategic alliances including R&D cooperation will vary according the substance of the actual agreement.
