This study was conducted to investigate the indiscriminate development occuring as a result of high-density land use per lot in residential areas of Seoul, which mainly consist of detached houses. The primary goals of this study were: (1) to suggest a block unit development method as an alternative architectural method of the current uniform development, in which high-rise and high-density apartments are usually built; and (2) to check the feasibility of the suggested method. Based on the analyses of the existing block composition types of residential areas, the prerequisite planning indices for applying a collective housing model were investigated. Subsequent to applying a collective housing type within each unit block, the collective housing model was analyzed. The results of the analyses showed that indiscriminate development was rampant in detached urban houses areas, and more than 70% of the buildings constructed before the 1980s needed re-development. The feasibility of the models was investigated depending on the models of low-rise and high-density collective housing, which utilize various block arrangements such as the court type, linear type, villa type, and composite type. The results of this study showed that the newly applied low-rise and highdensity multiple dwelling housing model in urban individual residential area significantly contributed to creating a good living environment in terms of both physical and psychological aspects.

This study is made to link lip the policy analysis theory flame and practice concerning the analysis of railroad tourism resources development policy and propose an alternative to feasibility for railroad tourism resources development policy in general. The specific objectives to achieve the purpose of this research are as follow; First. In consideration of railroad tourism resources development policy and theory of policy analysis idea and goals, for analysis of railroad tourism resources development policy analysis are to be instituted more systematically. Second, the theory of railroad tourism resources development policy analysis will be made more systematic and use it as basis of the said analysis for further.

The High-price development & testing tools and IP infratstructures are required for the development of system semi-conductors, but SMEs have not ability to prepare for them. Recently in terms of the miniaturization and the advancement of semiconductor process, the cost of the semi-conductor development have shown the rising tendency and the market-based design tools used are requied to be upgraded due to the advancement in the environment and technology. On the contray, many other contries such as Taiwan, Japan, China, and User are supporting this system semi-conductor industry. Korean government is trying to build the research infrastructure for system semi-conductor industry that aims to reduce the costs of the design infrastructure investment, to support the companies of system semi-conductor development and to incubate the fab-less start-ups. This study analyzes the feasibility of the project, by using the AHP analysis and the results shows that this project is considered feasible because the AHP overall score is evaluated as 0.840, the overall score is greater than or equal to 0.55.

The short circuit current problem is one of the operational problems that need to be solved by power system engineers in Korea. It is an important issue in the Seoul metropolitan area especially because of highly meshed configuration. Currently, it is regulated by changing 154 kV system configuration from loop connection to radial system, by splitting of the bus where load balance can be achieved, and by upgrading circuit breaker rating. A development project for 154 kV/2 KA SFCL application to 154 kV transmission system after 2010 is proceeding. In this paper, a feasibility study of superconducting fault current limiter (SFCL) is carried out in Seoul metropolitan area to find out the effects of its application and feasibility. This study shows that it can reduce fault current considerably, and as it can minimize the upgrading of circuit breaker rating, the economic potential of SFCL is evaluated positively.

The purpose of this study is to develop concept map as a tool of performance assessment in mathematics and to conduct feasibility test of the task. I developed and applied a concept map, an assessment tool, in the form of a mathematics performance task for 1st and 2nd year middle school students. I also conducted feasibility test of the task, and at the same time sought ways to guarantee reliability of the assessment procedure. Results of the task assessment can be summarized into the following four points. First, the concept map task was found to be appropriate for an assessment of mathematics in middle school. Second, results of all 10 factors on verification of validity of the content of the task were positive with over 50%. Third reliability of teachers who conducted marking of the four concept map tasks was high, all recording over .871 in correlation number.

A GDHS(Geothermal District Heating System) is a heating system supplying a group of districts with heat extracted from geothermal sources. The advantages of GDHS include saving fuel consumption as well as reducing air pollution. This paper presents a case study for the economic feasibility model and analysis of a GDHS with which central/individual heating systems are replaced. Configuring to a simplified GDHS which consisits of subsurface systems, surface systems, and transmission/distribution systems, we find out the properties of the system and the model parameters affecting the initial investment/operating costs in order to develop a classical economic feasibility model given geothermal temperature. Based on our model parameter space, we analyzed the geothermal development project of the Jejoo Island probabilistically given prior information such as the expected geothermal power, the demand size and the length of transmission/distribution pipes.

This paper want to do the feasibility analysis that it uses financial statements in order to attract foreign investment to enter in the Busan area. And this paper would be presented the plan about foreign investment revitalization. To that end, this paper would be deployed the following methods and scope. First, It defines to the concept of foreign investment, foreign investment region, and foreign-invested enterprises, I wish to loot at the economic effects of positive and negative effects through foreign investment. Second, this study's scope would be set up foreign investment area of Busan, and investigate the land development cost of invested enterprises, construction cost of enterprises burden, expected revenues, etc. Third, it classified three industry for the feasibility analysis of entered enterprises, so would be yield industry-specific analysis using financial statements to be pre-research. Forth, this paper is suggested a revitalization plan for efforts to attract foreign investment, for the future through economic effective analysis of foreign invested-enterprises.

Government imposed a duty to perform feasibility investigation on huge development projects which cost are higher than 50 million dollars on May 1999. This is to prevent waste of money occur from lack of review on huge public projects and raise the efficiency of government budget. Although maintenance and managing analysis method for public infrastructures are developed and proposed by other institutions as Korea Infrastructure Safety & Technology Corporation but it is not well applied on the aspect of the railway fixed time and costumer costs. Therefore a good point of quantitative and qualitative reference which fits railway character is need and following guidelines from the phase of feasibility study are need to prevent governments budget waste.
