Generation cooperations have focused on active power directly related to economic value. So, utility cooperation have taken expense to stabilize power system, although generator has responded quickly with variation of power system voltage and is controlled at real time. As a reactive power source, it is necessary for generator's capabilities to be verified. But domestic generators scarcely have been tested and operated to reactive power capability. In case of power system fault, operators would not quickly take a follow-up actions about reactive power disturbance. Therefore generator reactive power capability verification strategy must be developed, several generators is tested as examples since 2004. This paper is extracted from the test results.

The goal of this study is to make the government/users decide rationally with regards to the problems of the weapon systems management. Therefore it is necessary to develop how much precisely and through what methods the system should be cost. That costing policies should be determined under the considerations of the estimating expense and the expected benefit due to the applications of cost informations. After that, it must also be decided where the cost informations are used. We can suggest the cost results be used to find the most reasonable system among alternatives, the best producer, the most benevolent policy for user, and so on.

The length of city gas pipeline is increasing with expansion of natural gas transmission rapidly. A lot of the expense was paid for repair and maintenance with increasing of pipeline length and the cost of repair and maintenance by the corrosion was the highest. It is necessary to evaluate integrity in case of thickness reduction by corrosion. There are a lot of assessment criteria for corrosion defect in foreign countries but they are not suitable for application in the country directly. In this work, we performed the burst test and the finite element analysis for city gas pipeline, KS D3507 and KS D3631 for city gas transmission, and developed the assessment method of corrosion defect, which is suitable for domestic condition.

Recently WCDMA signal transmission technology by large output microwave antenna have showed reduction of human resources and operating expense. But the existing antenna brackets cost is very expensive also its structure and functions are complicated. Unit brackets, suspending some sensors, subjected to acceleration loads, often fail due to self-vibration. To prevent such failures, it is necessary to understand the fatigue failure mode and to evaluate the fatigue life using tests or analysis techniques. The objective of this study is to develop the component test specifications, which are applicable to predict fatigue life at initial product design step, for unit brackets using vibration fatigue technique. So its application is limited to installation and management. In this project, we studied about more convenient bracket for microwave antennas through improvement on the existing antenna bracket's shortcoming and could develop an improved universal antenna bracket system for simple installation and application.

The purpose of this study is to examine the perception of donors on the necessity of making improvements in accounting information system. Along with the increasing size and number of activities of nonprofit organizations, many people are more and more interested in their organizational efficiency and transparency. Accordingly, researchers and policy makers have focused on how to improve accounting information system and how to monitor nonprofits to efficiently obtain and use resources. We thus aim to provide some useful insights by analyzing the opinions of donors regarding the display of nonprofit statements, accounting system, and the intention of donation. Using survey data obtained from 263 respondents, we find that displaying functional expenses is considered to enhance the usefulness of financial reports. We also find that the filing and disclosure of financial reports is considered to be necessary. Respondents also require external audits, but not to the same extent as disclosure. Finally, respondents have a positive attitude toward making future donations.
