In South Korea, small photovoltaic equipment is increasingly adopted in more detached houses on the constant basis. With this broader use of small photovoltaic equipment, its systematic maintenance becomes all the more necessary. However, photovoltaic facility maintenance has been concentrated solely on large-scale solar energy generation plants in the country while hardly covering smaller facilities. In this research, the JEM rule and extant maintenance company services were analyzed to develop a proper maintenance model for small photovoltaic equipment. The maintenance service procedures designed herein are as follows: A small photovoltaic equipment user chooses a maintenance company and signs a contract. Once a contract is made, the Korea Energy Management Corporation provides a certain kind of incentive to the company. The company provides maintenance service to the user and receives a service fee. If such a maintenance service model is in place, small photovoltaic equipment efficiency is expected to increase and users could receive systematic maintenance services. Also the new creation of small photovoltaic equipment maintenance service would form a new market to generate more jobs for the society.

Software is more diverse and complex and the level of importance for the maintenance of application software to securely operate software is also gradually increasing in proportion. The calculation method for maintenance cost of application software applied in Korea public enterprises is involved in the range of 10 to 15% of development cost, depending on the Software Project Cost Estimation Guide. Moreover, as most software maintenance cost estimation procedures do not take into consideration of the risk factors related of maintenance, it can be seen as a main cause for the occurrence of maintenance related accidents. This study proposes a maintenance cost estimate model that takes into consideration of the risks related to the software maintenance activities to improve and resolve issues arising from the estimation of maintenance cost. In doing so, maintenance risk factors are analyzed and a risk index is derived through the analysis of risk levels based on the risk factors. Based on such analysis, a maintenance cost estimate method which reflects the maintenance risk index was established.

Purpose: This study was conducted to develop a community capacity builded exercise maintenance program for frail elderly women. Methods: As a guideline to develop the exercise maintenance program, the intervention mapping framework, including needs assessment, setting program goals, selecting theory-informed intervention methods, producing program components, planning program implementation and evaluation, was used. Focus group interviews with public health nurses and frail elderly women were conducted for needs assessment. Intervention strategies and components were formulated based on community capacity theory. Results: The developed exercise maintenance program consisted of strategies focusing on leadership development, partnership construction, organization development, community systematization of dimension of community capacity. A exercise maintenance program using health leader, health contract, exercise pocketbook, rhythmic activity suiting song and self-help group was included. Conclusion: The intervention mapping method was found to be useful to develop theory-based valid and community capacity builded exercise maintenance strategies for frail elderly women.

The safety problem of aged tunnels has been emphasized. For the effective maintenance, site inspection of tunnel structures and surrounding grounds are required periodically. Also, the determination of safety of tunnels is not a simple problem. So the role experienced engineer in the maintenance is very important and development of an expert system that can perform as the engineers, has been needed. In this study, from the results of numerical analysis in several case, new precision inspection rules which can substitute actual numerical analysis are determined by a commercial program FLAC and regression analysis under various parameters such as material property, lining thickness, overburden and laterial coefficients. They are added to the knowledge base to determine safety of tunnel lining. To verify the expert system, the results are compared with an existing tunnel diagnosis report. It can be concluded that the new rule are well represented the actual numerical analysis under various site conditions. Therefore it is expected that the systematic management for effective maintenance of tunnel structure will be possible.

In Korea, Green building certification system had been operated for more than 10 years and Expired certification buildings are ever-increasing. However, post management of building and qualification standard for re-certification(G-SEED) aren't exist, certificated green building don't have smoothly maintenance and management. Therefore, analysing the status and situation of similar system such as building maintenance and management, to suggest the direction of evaluation for green standard for energy and environmental design.

FRACAS(Failure Reporting, Analysis and Corrective Action System) is intended to provide management visibility and control for reliability and maintainability improvement of hardware and associated software by timely and disciplined utilization of failure and maintenance data to generate and implement effective corrective actions to prevent failure recurrence and to simplify or reduce the maintenance tasks. This process applies to acquisition for the design, development, fabrication, test, and operation or military systems, equipment, and associated computer programs. This paper shows the FRACAS development process and developed FRACAS system for a defense equipment.

The Nuclear power industry today faces a serious and rapidly emerging problem in reactor maintenance and occupational radiation exposure control. The basic problem is the need for much maintenance on nuclear power plants. The problem is seriously compounded by radiation exposure control requirements. Many studies are underway seeking solutions tut the industry is developing rapidly and new plants will not await the results of such studies. It is essential that attention be given to maintenance and exposure control in all phases of plant design, construction and operation.

The component and system of modern Railroad vehicles are advanced and complex. Maintenance policy is scientific and must be performed systematic. A vehicle operation and maintenance must become statistical analysis method. We must apply RAMS and System Engineering. We must apply the RCM theory in the maintenance management. The vehicle failure and maintenance charge must be reduced to a minimum. When we purchase the vehicle or component, we must reflect the technology. Also such system must be constructed. We will do technique development with the deed of such serial.

Vinyl greenhouse and glass house account for the greatest parts in the agricultural facilities. However, these cause the serious economic loss lacking of the maintenance guide in a lot of natural disasters. This study developed the maintenance guide concerning the vinyl greenhouse and glass house by collecting materials with literature review and improving problems with existing guides.
