It is not feasible for agricultural facility managers to estimate how severe damages are and what are causes of them when agricultural hydraulic facilities get damaged for some reasons. Moreover, it is nearly impossible for agricultural facility managers to take immediate actions to repair and reinforce the damaged structures. Thus, there have been needs for well-established systems to help agricultural facility managers understand its severity and causes, and take proper actions to reduce speed of deterioration and to repair/reinforce them. Thus repairing and reinforcing systems of agricultural hydraulic structures based on agricultural facility management policies, developed in this study, can be efficiently used in field works to determine top priority location and the budget of repairing and reinforcing projects if detailed information of damages in concrete structures and damage types are well compiled and classified with standardized image data complemented.

The purpose of this study is analyzing the frequent defect about each inspection part of Pre-qualification of residential building reconstruction and finding the cause of occurrence so that can supply a solution of the problem during the plalnning and constructure. The frequent defects are naturally following the deterioration and more occur in the structure body than a skin. The meaning that supply the cause and the managing method for preventing frequent defects about each inspection part is as follows. To prevent the defects, it is needed that the choice of the appropriate materials, giving a sufficient space for facilities, reliable constructure for the part of expecting the defects. The quality of life will go up due to making a good dwelling environment and extending the life cycle of structures from the inspection and managing the part of expecting defects.

Due to various kind of waterproof materials and methods, which is difficult to select the most appropriate to waterworks. The materials used to prevent the deterioration of the service life is short, because of the chemical erosion. So, in the 2010 Office of Waterworks Seoul Metropolitan Government has set new standards. Recently, SMC panel is a trend that is being applied to water treatment facilities. However, SMC panel has not yet implemented a performance evaluation. Therefore, this study to confirm that satisfaction for the Office of Waterworks Seoul Metropolitan Government of the performance requirements, when the applied the SMC panel to water treatment structure.

This study investigated the detection of corona discharge on polymer insulators at 13.2kV. Also, It will be analyzed by variety analyzers such as FT-IR, TA, and so on. It carried out an experiment and an actual measurement about corona detection using a UV-camera. This experiment and inspection would need to respect the above criteria. It was required to verify various experimental conditions and on-site inspection afterwards, but it was believed to minimize the measurement error by data-basing research results in a continuous manner and it was necessary to establish diagnosis technologies and standards in various electrical power facilities.

The purpose of this article was to evaluate the effects of reimbursement system on the basis of diagnosis-related groups(DRGs). We searched articles which was published from 1970 to 2000 using MEDLINE ； Key words "diagnosis-related groups, DRGs, prospective payment system, PPS. Then we reviewed 97 articles on classifying them into several categories of contents. It seems that the effects of DRGs in controlling hospitals cost in the U.S. was not clear cut. The U.S. Medicare PPS using DRGs remains vulnerable to compensatory increases in ambulatory care and long-term care facilities utilization despite cost per case and cost per admission being reduced. Also some research indicated the possibilities of deterioration in health care service quality. So putting theses results together, much more consideration is needed before the application of DRGs reimbursement system in Korea. Particularly there is the crucial difference between U.S. health care system and Korean, we must be aware of the limitations of DRGs and revise the DRG system to applicable in Korea.orea.

The number of domestic ice-rink is little by little increasing recently. Therefore, the demand for air-conditioning system to adjust adequately the indoor condition of ice-rink is constantly increasing. But, if air-conditioning system for ice-rink isn't designed properly, the problems such as fogging, ice surface condensation, structural deterioration, odors, generation of dew condensation on the surface of a wall occur. The solutions for these problems are to lower the relative humidify of indoor. The objectives of this paper is to apply of desiccant dehumidifier on ice-rink, solve these problems.

Railroad disasters are frequently occurred by man-made causes or natural causes. In general, man-made causes are illegal construction practices, deterioration with the lapse of time and railroad crossing accidents, and natural causes are rainfall. snow, wind, earthquake, etc. Of cause, railroad disasters by man-made causes are prevented from keeping the safety principle, constructing multi-level crossing, securing enough men of ability and financial resources and making a thorough check using equipments with high capacity. And railroad disasters by natural causes are also minimized by construction of disaster prevention facilities, introduction and operation of general disaster prevention system and reasonable train passage control. Therefore, to setup the criterion of train passage control for train safety at railroad bridge under heavy rainfall, risky factors, national and oversea criteria under such circumstances are reviewed and a scheme to setup the criterion is suggested.

It has little possibility that a cable causes any problem in electric power facilities. But when a trouble occurs in cable or cable joint, the damage is very severe. The main causes of the cable defections are bad cable making procedure, poor cable operation and deterioration according to the years. There are some cases to have potential problems due to many cable connection points, because of short length of cable, especially in 154㎸ system. In this study, novel method to measure partial discharge in cable joints is proposed and the effectiveness and the reliability of the proposed method is shown through experiment results of field.

As buildings and especially eco-friendly facilities are increasing, maintenance of the aged buildings are interested by many maintenance companies. Therefore, a lot of companies are increasing by the maintenance form. These Earned Value should try to minimize the increasing forms. Therefore, this study has an effort to gather data related to earned value of building facility maintenance and analyze the data in terms of local dimension, used duration dimension, building types dimension and so on in order to prevent the building deterioration.
