Linze-Donawitz gas (LDG) adjunctively produced in the steel mill contains over 60% of CO. Two processes that recover high purity CO from LDG were considered: COSORB and CO-Pressure swing adsorption (PSA). This study aimed to decide which one is more economically feasible than the other by techno-economic analysis (TEA). From the technical point of view of TEA, the process flow diagram (PFD) was constructed, the mass and energy balances were calculated, and the equipment type and size were determined in order to estimate the total capital investment (TCI) and the total production cost (TPC). From the economic point of view of TEA, economic performance such as return on investment (ROI) and payback period (PBP) was evaluated, and the sensitivity analysis was carried out to identify key factors influencing ROI and PBP. It was found that CO-PSA is more economically feasible due to higher ROI and lower PBP. The CO price highly influenced ROI and PBP.

The economic feasibility analysis including benefit-cost ratio and internal rate of return of a land consolidation and on-farm development project was mainly depended upon the direct benefits and costs arising during project life. Therefore the projects were neglected in allocating the government's financial funds and loans on account of the low economic rate of return of the project. Accordingly the extended benefit-cost analysis method should be introduced and adapted to cover not only the benefit s such as non-market values of environmental and food security fun ct ions of the project but also market values of the project outputs. The main purposes of this study are (1) to prepare a guide line for economic feasibility analysis based on the IBRD and ADB guidelines, (2) to estimate the benefits from productivity increase, labor saving, savings of O&M cost of farm mechanization and project facilities, savings of farmer's burden for their public health, increasing environmental and public functional value of paddy fields, improving food security condition and formation of peaceful and uncontroversial rural society by implementing the land consolidation and on-farm development, (3) to introduce the newly adapted analytical method as the extended benefit cost analysis which could make possible to be included the values of non-market goods such as the food security and the environmental public function of paddy fields. To carry out this study, the existing publications on the guidelines for economic agricultural projects were reviewed and consultation was made with a For the post evaluation study of the land consolidation and on-farm development project, field survey in Jigok and other comparative area were made to get available information. According to the project completion report, Jigok land consolidation and on-farm development project has 55ha of benefit area out of 69ha of gross area. The project was started in November 11th, 2000 and completed october 30th, 2001. The total project costs were amounted to 2,548 million won and the annual project benefits were estimated at 335million won evaluated by domestic market prices. The ERR(Economic Rate of Return) and SRR(Social Rate of Return) of the project based on the shadow pricing system were estimated at 4.4% and 16% respectively. On the other hand, the ERR and SRR based on the domestic market value system were amounted to 6.37% and 14.62%. In conclusion, Korean land consolidation and on-farm development projects have not carried out from the view point of economic rate of return under shadow pricing system but from the view point of domestic pricing system. For the future feasibility studies on land consolidation projects have to be carried out including the non-market values as environmental and food security function of the projects.

Seoul suffers from over congestion of outdoor signage. Signage is on everywhere including on windows, on entrance way, on every available space on the building wall. The excessiveness is up to the point that decorating surface of a building is almost meaningless and most signage is lost in each other's profuse presence. The competition to attract more attention is resulting in bigger, brighter, and more stimulating signage. As the result, outdoor signage of Seoul have lost its intended function to provide useful information and befallen to be viewed as visual pollution. As it is an important visual element of city view, the outdoor signage also serves important role of delivering needed information in proper way to enhance convenience of city life. At the same time, it is a very important marketing tool that is essential to economic activity. Outdoor signage also holds enormous potential to act as a visual and structural element to improve city view just as a beautiful architecture does. However, outdoor signage that does not consider the harmony with its surrounding environment can only be treated as visual pollution. The effort of Seoul to better the city view by improving the outdoor signage started at Jong-ro area. By reforming outdoor signage, the streets of Jong-ro achieved much more harmonious and aesthetically pleasing city view. The study went through analysis of current status and characteristics of outdoor signage of Cheonho-dong Rodeo Street, Gangdong district to suggest detailed design solution to reform the roadside view and to revitalize the street.

Modem biotechnology, specifically for the use of recombinant DNA(rDNA), has brought about a revolution in our ability to control and use life forms. Most of the world's leading countries view biotechnology as the key scientific and industrial discipline for the 21st century and are making all - out efforts for scientific and technological advance in the related fields. The impact of biotechnology on the nation's economy has been growing explosively as such diverse industries invested increasingly on the fruits of biotechnological research. However, such an impact could only be realized through concerted endeavours from the government to private sectors for guarantee of the successful technological advances in this scientific area. There are risks associated with every technology; the classical application of biotechnology has not been exempt. For example, the introduction of bio-tech to agriculture might be destroied the ecosystems. Therefore, to increase the research budgets by the government and private sectors, we need to identify the public attitudes and preference on the acceptance of bio-technology and on the potential economic value of it. For the study, we surveied 959 persons including students enrolled in college of agriculture, Chungnam National University. And to measure the economic value of biotechnology, we use the Contingent Valuation Method(CVM) which is considered as the new approaching method in the bio-technology field.

Many economic development practitioners view cluster theory and analysis as constituting a general approach to strategy making in economic development, which may lead them to prioritize policy and planning interventions that cannot address the actual development challenges in their cities and regions. This paper discusses the distinction between strategy formation and strategic planning, where the latter is the programming of development strategies that are identified through a blend of experience, intuition, and analysis. Cluster theories and analytical tools can provide useful informational inputs into a strategy making effort and they can also be helpful for programming specific interventions (i.e., strategic planning). However, they should not be used as the exclusive or even predominant framework for filtering information about the competitive advantages of a region or for formulating strategy. To do so forces strategy making into a conceptual box defined by only one highly stylized theory of regional growth and development.

The goal of current study is to carry out comparative analysis on the relationship between nature perspectives and their corresponding utilities by taking integrated approach combining economic values with environmental ones. The results are as follows. First, empirical evidence shows that the structures of happiness function differ according to nature perspectives. The anthropocentric-nature perspective is centered on economic value. Whilst, environment and social trust play an statistically insignificant role in deciding happiness levels. Secondly, the eco-centric perspective possesses a multi-facted structure of happiness function composing of income, environment, and social trust. In this vein, it is no reasonable behavior, from happiness maximization view, to focus on economic value vis-a-vis use value.

Using a data set drawn from 1419 college students, this study analyzes what implications clothing or fashion has on self-expression or image management in Korean society and who are more likely to use fashion as a image management tool in the process of interacting with others. Employing Pierre Bourdieu's concept of capital, we discuss three theories concerning correspondence between class and fashion: the theory focusing on economic capital in emphasizing the correspondence; the theory focusing on cultural capital in emphasizing the correspondence and the theory emphasizing relationships between fashion and other factors rather than class. Based on the theoretical examination, we select independent variables that can be grouped into status/class variables, or economic capital variables(such as subjective status, income, father's education, father's occupation) and socio-cultural variables, or cultural capital variables(such as possession of cultural capital, desire for upward mobility). Upon regressing strategic use of fashion on independent variables, we find that both status/class variables and socio-cultural variables are statistically significant in explaining the strategic mobilization of fashion for one's image production or social success. It shows that class as a form of economic capital has important effects on the strategic use of fashion, and cultural capital also has effects independent of economic capital.

The purpose of this basic study is to examine the economic feasibility analysis of Busan Central Library, which was included the construction feasibility analysis conducted as one part of the Busan Central Library Construction Master Plan. To achieve the purpose of this study, it was accomplished to do Benefit-Cost analysis, Net Present Value, Internal Rate of Return. CVM(Contingent Valuation Method) was used for calculating the benefit; we investigated two CVMs for Busan Central Library, which are for central construction site and for outer construction site. The results show that the construction of Busan Central Library in the central site would be feasible from the economic point of view. On the contrary, the construction in the outer site would not be feasible economically.

The purpose of this study is to estimate regional economic effects of spatial diffusion of wildfire using Cobb-Douglas production function of agriculture and forestry. The analysis is applied to Gangwon and Gyeongbuk provinces where are the most damaged of wildfire in Korea. The damaged areas are derived from multiplied by the occurrence probability of wildfire and diffusion areas of wildfire for micro-spatial unit level with ArcGIS techniques. The models of wildfire provides that the spatial diffusion of wildfire increases with the rising of highest temperature and average wind speed. Through the production function, value added of Agriculture and Forest sectors get damaged where the Cos-converted slope aspect of mountains are toward the South. The production model provides reductions of regional value added by increasing damaged areas of wildfire. It reveals that the most damaged region is Andong city in Gyeongbuk province, where value added loss is 1.25 billion Won, which is about 0.72% of total value added in agriculture and forestry of the city. As a view of policy makers, it needs to be considered to establish prevention policies against wildfires because regional economic losses from wildfire are depending on geographical conditions and performances of the major industry related to wildfire's diffusion such as agriculture or tourism sector according to the result of analysis.

There are two viewpoints in agricultural extension. One is economics(econometrics) the is non-econometric social sciences. In Korea economic means mainstream economics. Most mainstream economists have tried to solve the social and economic problems of Korea using their basic principles and econometrics. This mainstream economics have been supported by the Korean government and many people due to its convenience, effectiveness, and clearness. However, Agriculture and agricultural extension should be studied through multidisciplinary approaches after considering their specific social structures. Especially, Korean agriculture and agricultural extension have many aspects that can not be easily explained by main stream economics. In this study, the researchers will; 1)identify the origin, growth, and limitation of mainstream economics, i.e. econometrics 2)identify the paradigm and the view of social sciences and out-of-mainstream economics to make up for the limitation of main stream economics in explain the agriculture and agricultural extension in Korea, and 3)suggest to use multidisciplinary approaches to solve the agriculture and agricultural extension in Korea.
