공동주택은 준공 후 일정기간이 경과하면서 사용된 자재의 내구연한에 따라 노후화 현상이 나타난다. 구성자재의 내구연한에 의해 일부부위는 짧은 시간내에 수선을 하여야 하며 어떤 부위는 장시간이 경과한 후에 수선을 하기도 한다. 이와 같이 건물에 나타나는 다양한 노후화 현상에 대해 체계적일 유지관리를 하려면 준공후 경과년수에 따른 장기적인 계획수선을 필요로 한다. 장기수선계획작성에는 건물의 공종에 따른 수선시기를 예측하여 이를 기초로 작성해야 한다. 공동주택에서 장기수선계획이 계획에 지나지 않으며 실질적인 수선에 적용되지 못하는 주요인은 앞으로 수선이 예측되는 건물의 각 부위에 대한 수선시기를 예측하지 못하기 때문이다. 이에 본 연구는 전국에 산재한 공동주택을 장수명화하기 위해 장기수선계획을 활용하여 .해당단지의 부위별 재료의 특성을 반영한 수선주기 및 수선시기를 예측하고, 공동주택 관리자가 주기적 점검, 진단, 교체 등의 사항을 유지관리 캘린더에 의해 단지별로 자동관리할 수 있는 웹기반 유지관리 시스템을 제안하다.

Purpose: As the improvement in quality of medical environment and the spatial consideration for the prevention of infection in the hospital have become increasingly important in the recent years, specific and practical planning for air conditioning room's area has become a major issue accordingly. However, the air conditioning room tends to be discussed focusing on technical factors such as air conditioning systems that are irrelevant to building plans, while discussions of most departments related to the medical functions have actively taken placed. Therefore, this study aims to investigate the factors influencing the planning for the air conditioning room area, and through subsequent analysis of the area of the air conditioning room, to propose a way to improve effective planning for the air conditioning room area. Methods: This study examines the case hospitals that fall into two types: each floor supply system and concentrated supply system, and compares and analyzes the air conditioning room area-related factors and the characteristics of changes in the interior of air conditioning room before and after remodeling through air conditioning floor plan of those case hospitals. Results: The air conditioning room can be classified into the net area of the functional space such as duct passages, and the public area such as aisle space, and of those the public area is an important factor in calculating the area of the air conditioning room. The public area of the air-conditioning room should not be planned considering only the spaces for mobile passage or maintenance activities, but should be planned taking into account internal changes such as expansion and replacement of equipment in the future from the beginning. Implications: When planning a medical facility, it is used as basic data for the planning of the air conditioning room area, which is a significant fixed factor in the initial setting.

This article introduces the five functions of the national innovation system (NIS). As the national innovation system is a kind of social systems in the national level, the five generic functions of open system-production boundary spanning, maintenance, adaptation management functions-are applied to the NIS. The production function is the primary process, which produces innovative products and services of the NIS. The boundary spanning function is the function of procuring the input and disposing the innovation output or aiding in these process. Experienced R&D human resources, R&D funds, technology etc. belong to the input of the NIS. The maintenance function is responsible for the smooth operation and upkeep of the system in terms of various conditions. The adaptive function is to help the system change and adapt, scan the environment for problems, opportunities, and technological developments. It faces outward for the survival of the system from the long-term view. The management function carries out planning and controlling the overall activities for the other four functions in order to run the system. Finally it discuses implications for the diagnosis and the decision making process of S&T policy.

This paper discusses a knowledge-based system being developed by KAIST and KEPCO to assist planning the annual maintenance schedule of power units. To meet users' requirements, we have designed the system with several features: man-machine interaction, catalog system, user-friendliness, the hybrid-system of math-model and knowledge-base. In this paper, we introduce the outline of our system.

A nationwide questionnaire survey was conducted to investigate the actual conditions of local authorities in operating and maintaining sewerage systems especially for urban flooding. The questionnaire includes the incidences of flooding since 1980, the existence of any guidance for preventing flood damage and the design frequency currently used for sewers in each local authority. Among 160 local authorities responded to the survey, 95(59.3%) has experienced flooding more than once since 1980 while only 36(37.9%) of the 95 has prepared operation/maintenance guidelines for flooding. Most of the respondents have applied the 10 year design frequency for sewer design and 57(35.6%) of them agreed to adjust the 10 year design frequency regulation.

The purpose of this study is to provide an remodification method for elementary school complex facilities in Seoul Metropolitan city. This study analyzes the questionnaire survey for 568 entire elementary schools and the questionnaire survey for school facility complex project operated 44 elementary schools. Then the result of this study was deduced from the comparison between the 568 entire survey data and 44 survey data in terms of the cognition of school facility complex project, the required type of facility and the problems of complex facility maintenance and operation. Four major findings were revealed as the result of research. First, there is a very high agreement with the school facility complex projects. Second, it was need that the process of planning and design was remodified to enhance participation of parents of students and local residents for selecting an appropriate complex facility. Third, education environment and student safety should be protected from any other school facility complex environments. Fourth, an agreement and regulation is needed for more effective maintenance and operation of school complex facilities.

Occasionally, equipment in a distribution system fails due to damage from weather, vandalism, or other causes. In addition, it is recommended practice to have some way in which maintenance or replacement of every element in a system can be performed without causing lengthy interruption of electrical service to the customers it feeds. Thus, alternate sources, paths, and configurations of service must be planned so that both failures and maintenance do not affect customer service beyond a reasonable amount. In some cases, planning for alternate routes of service during equipment outages or emergencies -- will be the major aspect influencing selection of a feeder's capacity, type of route, or layout. We want to know the relationship between molt-dividing multi-connection and distribution reliability for contingency support considerations.

To get competitiveness in international markets, it is essential to provide low acquisition, maintenance and operation cost with high reliability, availability and maintainability. It can be achieved by lowering development cost, making proper maintenance planning and scheduling strategies, allocating man power and logistic cost properly. In this paper, we introduces the research on making a model for estimating the life cycle cost of newly developing magnetic levitation train system in Korea. To develop a proper life cycle cost model, we broadly analyzed specs and standards and compared the life cycle cost model developed in other country. Finally, we suggests strategies to develop an unique model for the magnetic levitation train system developing in Korea.
