The purpose of this syudy is to set up a proper repair plan and to extend the remaining lifetime of them by measuring the remaining lifetime of reinforced concrete structures quantitatively. This method is based on the actual research on age deterioration, carbonation depth and covering depth of the reinforced concrete structures. Also, it measure the remaining lifetime through quantitatively defining the probability of steel corrosion by the damage of steel corrosion. By doing that, we proceed the proper repair plan after reviewing the possibility of lifetime extension.

In this research, these days extension of electric power station plant and new building plan is tending to more bigger size and much more cooling water for discharge, therefore submarine structure for discharge has needed various types and the large one. The domestic power plant was applied to once-through CW system structure that pipe line type, immersed PC-box culvert type and submarine headrace tunnel type of discharge structure. It is possible that the future structure type of submarine discharge is expected by a case research of application and plan.

For the greenhouse 9as emissions' reduction of fossil fuel, the energy policy on the promotion of alternative energy should be implemented. Accordingly, national policies on the development and promotion of alternative energy were made, and related laws and regulations are being made, and comprehensive plans should be followed. The policies and strategies for promoting the renewable energy have been insufficient in comparison with those of the developed countries. This paper suggests the spread extension plan of renewable generation through generation development and priority purchase.

This study was performed to plan pollutant loading allocation by sub-watershed at Kumho river basin located in the north Kyeongsang province. HEC-geoHMS which is extension program of ArcView was used to extract sub-watershed. To simulate water quality, Qua12eu model was calibrated and validated. BOD was simulated under several scenarios to evaluate reduction effects of pollutant loading. Uniform treatment and transfer matrix method was considered. Effects of headwater flow rate and efficiency waste water treatment plant were also considered.

Sequential test plans are characterized by decision rules for accepting or rejecting compliance, or continuing the test at my test time. They are determined by selected values of risks and discrimination ratio. The sequential test plans in the international standard such as MIL-HDBK-781A are based on the assumption that the underlying distribution of times between failures is exponential. In this paper, sequential test plans are extended to the Weibull distribution case. Simulation studies are performed to examine the reasonability in this extension.

The government has implemented operating the bus information terminal (hereinafter, 'BIT') to use by building it at a major bus station to solve the problem of traffic congestion. Busan Metropolitan City has been continuously expanding the installation of 'BIT' since 2003. However, there are few research on the factor to use and satisfaction survey on 'BIT' from the perspective of the users. This study, in an effort to inquire into the 'BIT' utilization factor and its vitalization plan, conducted a face to face survey of 172 citizens who had the experience in the 'BIT'. The result of the data analysis showed that usability, convenience, and availability were the critical factors for a BIT use. In addition, the general intention to use 'BIT' was found to be very high as much as 90.7%. The contributions of this study are as follows. The academic contributions is that it proved the relationship between usability, convenience and the intention to use suggested by the information technology acceptance model is supported even in case of 'BIT.' For the practitioners this study provides ground data for a local government to make a plan of a BIT extension.

In the information-oriented society, the paradigm of education has changed from the existing traditional teaching-centered education to the learning-centered education. In the Web-based Learning System which an learning-centered educational environment using the internet, students should have responsibility of their learning as taking more opportunities to participate their learning positively, to control their process of learning and to evaluate their learning by themselves to improve self-directed loaming ability. In this paper, the Web-based Learning System with a Self-Study Plan to lead students to select own purposes and methods of the study and write a self_evaluation is developed. The Self-Study Plan is a guide to lead the process, an order to have an individualized study and a report to evaluate own study. In addition, the suggested System is designed through object-oriented method using the extension mechanism of UML to archive the improvement of reuse and maintenance.

The existing universities enlarged the scope, filled up the facilities. And many new universities are founded by increase of university students, the change of curriculum and extension of installations for new curriculum. However, the planning for university campus hinders desirable activities in campus and also the origin function of university, because of the problems caused by an application of a uniform planning standard that lacks in logical analysis and such a short step as the occasion demands for the growth and the change of the university campus changing more rapidly than any other field in society. This dissertation is for space program beginning from architectural explanation and basic planning concluding a general structure-planning for land utility, circulation planning, and building layout planning in order to find the practical solution for the applicable campus plan. The contents of this dissertation is summarized below. First, I studied the characteristics of the university, the structure of the university facilities and the expansion the development process of the campus. Second, through the case study of domestic campus planning, I analyzed the characteristics and the problems about space programming, facility layout planning, circulation planning and exterior space planning. Third, in the basis of the above analyses, I set up the directions of comprehensive campus master plan.

The objective of this study is review effective business reorganization measures for tackling financial difficulties for financial managers. The major cause of business failure is incompetent management. Business failure occurs when a company is unable to meet its current obligations, or the net worth of the company is negative : usually the signs of business failure are predictable in advance of its actual accurrence. Discriminant analysis as well as other analytical tools - profile analysis, dichotomous analysis, analysis of likelihood ratios - have been used to predict business failure on the basis of various financial ratios , among those, discriminant analysis has been tell known an excellent technique in predicting business failure. The first question to be raised is whether the business is better off, dead or alive. Assuming the decision is made that the firm should survive, reorganization procedure should be considered. The informal procedures of voluntary settlements used in reorganization are extension : composition and liquidation by voluntary agreement. Unless this settlement is possible by those means, the case goes to the courts for 1ega1 solution. If the court decides on reorganization rather than liquidation, it will appoint a trustee to control the firm for reorganization and to prepare a formal plan of reorganization. the plan must meet the stand of fair, equitable and feasible. In that case, the court will approve the plan.

This study compares and contrasts the Wales and England Organic Action Plans (WOAP and EOAP) and a Korean regional Life-Food Development Plan (KLFDP) in order to facilitate the development of the organic sector in Korea. Early action plans, for example, the first WOAP (1999) focused support on developing the supply of organic products whereas later action plans focused on marketing and consumer. OAPs may not only provide specific issue-solving roles by proposing new policy measures but also perform a regulatory role as a controller for organic sector development as a whole. The current KLFDP seems to stick to the former role but hardly has the latter role such as setting priorities, harmonizing various conflicting policy measures and factors and performing evaluation process for further progress. To secure better harmonized and sustainable development of Korean organic farming sector, constructing comprehensive national-level organic action plan, which has policy developing, implementing, regulating, evaluating and evolving functions, might be the most efficient choice.
