Life time of facilities is different In case of operating environment and frequency of use. So, the durable year of the facilities is only considered to replace the facilities at present. Thus, system management is needed economical assesment based on condition evaluation through performance analysis of facilities. This research makes a proposal for scientific condition evaluation table through physical assessment, performance analysis assessment, durable years assessment about satellite communication facilities being used in K-water. Consequentially, reasonable replacement plan is established for satellite communication facilities.

To minimize the impact of urbanization, accurate performance evaluation of Low Impact Development (LID) facilities is needed. In Korea, the method designed to evaluate large-scale non-point pollution reduction facilities is being applied to LID facilities. However, it has been pointed out that this method is not suitable for evaluating the performance of relatively small-scale installed LID facilities. In this study, a new design formula was proposed based on the ratio of LID facility area and contributing drainage area, for estimating the Stormwater Interception Ratio (SIR) for LID facilities. The SIR was estimated for bio-retentions, infiltration trenches and vegetative swales, which are typical LID facilities, under various conditions through long-term stormwater simulation using the LID module of EPA SWMM. Based on the results of these numerical experiments, the new SIR formula for each LID facility was derived. The sensitivity of the proposed SIR formula to local rainfall properties and design variables is analysed. In addition, the SIR formula was compared with the existing design formula, the Rainfall Interception Ratio (RIR).

As the exiting school facilities become old and unfit for new curriculum, the systematical remodelling process based on its educational and physical functions is required. due to the inadequate maintenance and repairing practices, unnecessary costs are expended. Therefore, this study aims to establish a remodelling decision-making model for improving the educational environment of the existing school facilities. According to the budget system, it proposes the concept of remodelling that includes the activities of extension, reconstruction, repair and improvement. This study classifies the performance evaluation for school facilities as that of safety, durability and educational function, and articulates the assessment standards, methods and elements. In the end, it suggests a rational model for remodelling decision-making that can provide efficient and comprehensive remodelling process, economic and sustainable school development.

Military facilities with masonry construction have a great portion in the whole military facilities. But lots of them have been used for more than 20 years, the degree of deterioration of the facilities are very serious. Futhermore, as small budget for the facilities maintenance and poor maintenance, the performance of the aged masonry facilities have continually decreased. We suggest a structural performance assesment criteria for the military facility through literature review, interview with experts and questionnaire. The assesment of structural performance includes the inclining and sinking degree of the facilities, durability of materials and resisting force of the structural members.

Accurately evaluating and predicting the performance of facilities is a key task in establishing a maintenance strategy for facilities. The importance of performance evaluation is becoming more pronounced, especially when the aging of facilities requires a huge budget. In this study, performance assessment models were developed for road and railway tunnels. Delphi analysis was performed to identify sub-elements necessary to evaluate the performance of a tunnel. The relative importance of the evaluation factors was derived from the AHP analysis. The correlation analysis was performed between each assessment factor and the final result to verify the significance of the model. For the correlation analysis, the survey data measured through precision safety diagnosis in tunnels in use was applied. The cost effectiveness analysis was also conducted according to the scenarios with different composition of performance factors in order to improve the practical applicability of the evaluation model developed in this study.

Purpose: This study was to identify nursing interventions which were perceived highly in the importance and performance of nursing interventions by nurses in long-term care facilities for elderly. Method: Data was collected from nurses working in long-term care facilities for elderly over 2 years who participated in continuous education by Korea Association of Senior Citizens Welfare Institution. Data was analyzed using mean and paired t-test to compare difference between the importance and performance of each nursing intervention. Results: Among 264 nursing intervention, 49 nursing interventions were considered highly important and performed very often by nurses. Especially, 11 nursing interventions had significant difference between the importance and the performance, which meant that nurses perceived them as the most important and they were not implemented often as much as that by nurses. Conclusion: The results of this study revealed that what kinds of the nursing interventions were perceived highly important and performed very often by nurses in long-term care facilities for elderly. These nursing interventions can be utilized in the development of standardized nursing intervention classification to be used for the long-term care facilities for elderly.

Infrastructure is provided to the user through long-term project period and large-scale working expenses. Existing facilities are getting old as time goes by. Accordingly, proper maintenance is required and generally more maintenance cost than initial invested cost is needed during life cycle. Therefore, a specific plan that just increases the value of facilities is required by evaluating performance of facilities and inputting minimum maintenance cost. Value engineering that increases the value of object by systemically analyzing Life Cycle Costs and function is actively promoted at the design phase of construction. These efforts can increase the performance of facilities at the maintenance phase of infrastructure. This study is to search how to evaluate the performance of Roadway by utilizing function analysis, as a core part of VE in the maintenance phase. In order to this a new evaluation criteria were proposed by adding an evaluation items to the existing criteria through the research of old documents, status of roadway maintenance and function analysis of VE. The results of this study may promote the effective performance evaluation to determine a resolution of roadway congestion in future. A succeeding study using the proposed evaluation criteria will be required.

It is important to estimate the capability for the facilities and the condition of schools continually and correctly because the structure's life is remained more longer through the effective building control and preservation. In accordance with above of that, it is required to understand the knowledge about all matters at the stage of management for educational facilities and establish the procedure of the facility management consistently. This research suggests the method, which remains consistent and objective and deals with the total functional degree by following ㄴthe way to systemize the management plan of the facility estimation. The functional estimation of the existing facilities will be useful to make an plan for repair, maintain and checking of them as well as be the standard for remodeling and the educational facility duration, including long period project for building mending.
