This paper attempts to evaluate an environmental regulation program which enforces installation of filtering equipment to reduce major air pollutants from used diesel vehicles. A real option model is presented to incorporate fuel cost uncertainty and irreversibility of emission-reducing investment. A finite-life option based on finite difference method is developed to consider the limited life expectancy of used vehicles. After taking into account social benefits from emission reduction and costs from decreasing fuel efficiency after the adoption of filtering technology, the result finds overall positive performance of the Pollution Reduction Program. However, the result suggests that the Program be designed to be more specific to vehicle types to improve program performance.

Location decision problems of franchisees which determine revenues and costs in business are one of the most important issues in franchisor research. The major portion of franchisees are located in Kyunegi-do and 5 major cities in Korea. What's the reason behind this fact? The purpose of this research is to provide the rationale for location decisions of franchisor businesses. Based on the break-even analysis, we conclude that major decisive factors of location decisions are demand and costs of franchisor businesses. At the good location which can attract many customers, franchisor businesses can be much more competitive than independent stores. However, at the bad location, franchisor businesses can not be maintained because of high costs.

We consider the economic analysis of the domestic natural gas DSM (Demand Side Management). Since the demand of the domestic natural gas decreases in the summer and dramatically increases in the winter, the necessity of the DSM that will smooth the demand pattern of the natural gas is emerged. The economic analysis of the DSM program is used as a main tool for screening the DSM. This paper suggests an economic evaluation method for the domestic gas DSM from the perspectives of participants, Korea Gas Corporation, local distribution company, non-participants, and total resource. The high-efficiency gas boiler is selected as a case study to illustrate the economic analysis of the natural gas DSM.

Recently, it is very important to create economic value as well as develop core algorithms and technologies in the field of R&D. Various R&D projects make an effort to do the technology commercialization of their results and, as part of efforts, many studies on business model(BM) are conducted to create economic benefits in using the developed technology. However, it is difficult to use the general business model methodologies, which are usually utilized for companies, to the government's research due to different processes and characteristics between them. And for the practical application of business models, it needs to systematize conceptual business models in technical perspective through technical architecture analysis. In this study, a business model development process and a technical architecture analysis for national R&D project is developed for the technology commercialization. In addition, the process is applied to Korean Land Spatialization Program (KLSP) organized by Ministry of Land, Transport and Maritime Affairs to verify the feasibility of its practical application.

Agricultural extension service in Ethiopia was started in early 1950s with mandate of transferring local research outputs and technologies to farmers, and importing technologies and improved practices from abroad. Extension service provided in this early time was limited to areas surrounding the experiment stations. Since then, Ethiopian Agricultural extension service has passed through at least five stages: the land grant extension system, the Comprehensive Package Programs, the Minimum Package Projects, the Peasant Agricultural Development Program, and the Participatory Demonstration and Training Extension System (PADETS). The comprehensive package extension program was initially implemented in selected pilot areas and eventually to be scaled up to cover about 90% of the farming community within 15-20 years time. The program used demonstration plots managed by development agents and used to train farmers organized through various field days. However, since all of these programs were operational in only small areas, the vast majority of the country was out of their reach. Through Participatory Demonstration and Training Extension System, the extension service in Ethiopia has come under the spotlight and government debates and external reviews are putting additional scrutiny on the system. Despite this long history, the system is still in its infancy in terms of coverage, communication and institutional pluralism. Currently in Ethiopia the Agricultural extension is provided primarily by the public sector, operating in a decentralized manner through which extension is implemented at the district level. Therefore, the main focus of this paper is to scrutinize the past, the present and the future Agricultural extension system in Ethiopia.

The government announced the Housing Welfare Roadmap (November 2017), to expand the supply of public rental housing by reconstructing aged long-term public rental complexes. Also, remodeling projects for complexes with low business feasibility of reconstruction projects are recognized as an alternative to supplying public rental housing in urban area. This study analyzed influence factors by dividing them into project feasibility, architectural plan, urban & residential environment plan, and legal system groups in order to establish a plan for long-term public rental housing remodeling project. Futhermore, this work conducted the principal component analysis to get the principal component factors among the influence factors of each group, and the weight analysis to calculate weighting of them. In addition, major influence factors were derived by calculating the relative importance score (RIS) of each factor. Lastly this paper validated the major influence factors and applicability of the procedure to select 3 complexes that can be reviewed for remolding project among 33 long-term public rental housing complexes located in Seoul. The results of this study are expected to be useful when establishing a remodeling project plan for long-term public rental housing.

최근의 치수계획은 과거 제방일변도의 획일화된 치수계획에서 탈피하여 면 개념의 다양한 치수대안을 고려하고 있다. 본 연구는 과거 홍수피해 예방을 위해 일차적으로 고려된 제방사업과 이의 대안으로서 계획빈도의 홍수발생 시 잠재적 피해예상지역에 대한 주민이주사업을 비교하여 제방사업이 갖는 정책적 효용을 평가하였다. 이를 위해 제방이 없다고 가정한 CASE I과 현 상태를 기준으로 한 CASE II로 구분하여 제방보축사업과 제방신축사업을 비교대안인 주민이주사업과 비교 평가 하였으며, 사례연구는 낙동강 본류의 황강 합류후부터 남강 합류전까지 구간을 대상으로 하였다. 제방신축사업과 보축사업에 대한 각각의 주민이주사업의 비용 대비 효과를 사례지역에 한정적으로 분석한 결과, 경제성 측면에서 주민이주사업이 전반적으로 제방사업보다 유리한 것으로 나타났다. 이는 지역적 특수성을 전제한 결론이나, 향후 치수관리를 위한 정책수립의 대상이 '하천' 보다는 '지역'에 맞추어 져야 한다는 것을 시사한다.
