PMT(Preventive Maintenance Template) is a standardized maintenance program that describes maintenance items & period as operation condition to increase component reliability at the component level. The existing maintenance programs are focused on time based maintenance to inspect and repair component depend on fixed period. But recently, we have developed advanced maintenance program(named PMT) to increase reliability and optimize maintenance program of the plant significant component. This paper presents how to develop the PMT for nuclear power plant's static exciter.

This paper presents development of program for generator maintenance scheduling. The maintenance scheduling of generating units is a dynamic discrete combinatorial optimization problem with constraints to determine the optimal maintenance periods of each generating units for a given planning periods. The developed program is designed so as to provide the maintenance schedule satisfying the operating reserve margin levelization and the procurement of proper reliability. In order to verify the effectiveness of the developed program, the numerical study has been performed with the practical data in 2005.

The purpose of this study is the development and application of practical education program for the security of semiconductor equipments maintenance technology. For securing the semiconductor equipments maintenance technology, this study aims to research on the Training and Development. The main field of HRD is about the Training and Development. We develop the practical education program applying the ADDIE Model to conduct the education training. This developed program tests the education training on the officers of Samsung Electronics, the maker of semiconductor. By the test, we hope to provide the technology education program focusing on the practical experiences of systematic and effective companies.

The systems of the nuclear power plant are designed based on the User Requirement Document, and Korea Hydro & Nuclear Power Co. (KHNP) implements preventive maintenance activities to keep the specific design function of the system consistently. To monitor the preventive maintenance effectiveness, KHNP has also developed maintenance effectiveness monitoring (MR) program based on NUMARC 93-01 since 2003, and has implemented the program in all operating plants. Recently, KHNP has upgraded MR programs by reflecting implementing experiences ; reestablishing the performance monitoring level, improving analysis for standby function and performance criteria for passive components, reestablishing the availability performance criteria and the performance criteria for the same type of components. These upgraded MR programs will contribute to enhance safety and improve equipment reliability through monitoring maintenance effectiveness.

Railway signal system has been more complex, larger and required high reliability. So, maintenance by experience must be changed to optimize maintenance program or introduced systematic method for estabilish new maintenance program. In this paper, we introduced the maintenance period decision method which are Age based method and Block replacement method based on the failure distribution for the equipment. So, we allocated optimum maintenacne period for the railway signal equipment using block replacement method.

To systematic maintenance and record 10,000 port structures, under Ministry of Maritime and Fisheries, data base management system is required. In this study, POMIS(Port Maintenance and Information System) program is developed for this Purpose. In this program, records for inspection and repair for the various type of port structures can be maintained and operated through internet. Thus ministry can efficiently maintenance and repair port structures and systematically manage computerized maintenance and repair data.

Purpose: The aim of this study was to identify the closeness, self-esteem and intention of exercise maintenance in the elderly participants of the BeHaS exercise program. Methods: Thirty-one elderly participated in the BeHaS exercise program which held 1 hour a week for 8 weeks. Data were collected by self-report questionnaires. Analysis of data was done using UCINET 6.0 for closeness and SPSS 22.0 program for frequency and Wilcoxon signed rank test. Results: The score of closeness, self-esteem and intention of exercise maintenance in pretest were significantly higher than those of posttest relatively(p<.001, p=.040, p=.007). Conclusion: These findings suggest that the BeHaS exercise program for elderly can be effective nursing care to improve closeness, self-esteem and intention of exercise maintenance.

The maintenance of educational facilities is divided into inspection and management of facility managers residing in the school and Educational Environment Improvement Projects(EEIP) to carry out maintenance work. Educational support organizations collect maintenance requests through facility inspections by school-specific facility managers, and carry out numerous maintenance projects during the year. The EEIP has the characteristic of Program Management with interrelationships between projects, not multiple projects management. The purpose of the EEIP is to eliminate the inconvenience of school facility users and increase their satisfaction, and achieving the goal is judged to be successful. Despite the importance of management and performance measurement utilizing Critical Success Factor(CSF) for the operation of successful educational facility maintenance management programs, the system for achieving the goals is insufficient. This study derives CSFs for each stage of the EEIP for the success of the EEIP. The CSFs for each stage of the EEIP is expected to serve as a basis for evaluation of educational facility maintenance management programs and can be used as an evaluation index in the future.

As a building is getting large-scale, composition and intelligence, it is required the stability of building electrical facilities. And it is very difficult of rapidly repair on a breakdown of building electrical facilities. Therefore high-reliability and efficiency of building safety is required. And thus, this study presents the repair-maintenance support program for preventive maintenance on a builing electrical facilities. This program makes offer some functions, facilities history input mode, checking and result mode. User can be made offer the cause and effect information of facilities-faults by this preventive maintenance program.

This paper deals with the Performance Based Logistics(PBL) application scheme pertaining to optimal maintenance program for logistics of Korean Fighter Experimental(KF-X) Project. For enhancement of the performance based logistics system application to KF-X program the selection of appropriate standards fit to maximize cost-cutting, a set of performance metrics fit for the purpose of the contract, foreign technology dependence of core equipments and parts were considered. Thus, selecting appropriate standards fit for Korean logistics environment, domestic maintenance enterprise for stable rate of operation of KF-X, a systematic reliability task that is able to measure quantitative combat capability are suggested.
