This research is carried out to inspect the Apartment Management System of Japan, to examine the similarities and differences between the Korean Apartment Management System and the Japanese Apartment Management System. First, as the basis law of apartment management, there exists the Building Unit Ownership Act, the Promotion Law fur Adequate Mansion Management of Japan, the Housing Law, Housing Execution Law and Rule of Korea. Second, the Association of Apartment Owners, an organization of owners of apartments in Japan and the Commission of the Representatives of the Occupants in Korea become the subject of maintenance. The Japan structure is made of the Assembly, the Director and the President. The Korean structure is made of Regular and Temporary Conferences and elected Officers(1 president, at least 2 directors and at least 1 inspector). The Commission of the Representatives of the Occupants and the Organization of Owners of Apartments make bylaws and diverse maintenance rules. Third, the foremost reason why the Korean structure of maintenance of apartments is less efficient than Japan is because of the small number of people dispatched to the living-environment maintenance team and their short terms. It is necessary to grow professionals related to this sector and to have enough public servants that specialize in this. Fourth, although it is compulsory to make long term plans for maintenance based on the Housing Law, because the reserve fund is decided by the maintenance rule(with no compulsory standards of reservation) of each apartment, it is difficult to reserve an adequate amount of reserve fund. So as in the example of the state of Hawaii in America, based on long term plans for maintenance, an execution rule of the Housing Law should be made which enforces to reserve at least 50 percent of future maintenance expenses.

In case of the BTL Project for current educational faculties, the proper standards to analyze those said educational standards lack, so it is very difficult to conduct an exact analysis and those improper standards are problematic when proper management and maintenance costs are calculated. In case of such educational facilities, as students have to use them safely for a long time and the quantity of their activities and the status of their physical growth based on individual classes, as well as the features for use by facility and the regional characteristics are different, other standards for maintenance and management must be considered unlike an apartment house. Thus, in this study, to set up the standards considering the features of educational facilities, the maintenance and management level suitable for educational facilities is presented by comparing and analysing that required to maintain and manage an apartment house, targeting the experts specializing management of educational facilities.

Large hospitals such as medical centers provide not only medical services, but also carry the responsibilities for emergency refuges, medical researches and education. The function of large hospitals is as important as other infrastructure systems such as highways, bridges, and utilities. When disasters occur, the hospitals have to provide emergency medical services for victims and support the patient's needs of health. In order to keep a smooth operation of hospitals, the maintenance management of hospital buildings should be carefully investigated. However, there are few researches focused on maintenance management issues of hospital buildings. This paper investigated the National Taiwan University Hospital (NTUH) and established a maintenance cost database. The NTUH is the best-known and most high-renowned medical center in Taiwan in which more than 4,000 employees serving approximately 2,000 in-patients and 7,000 out-patients daily. The data were collected from the NTUH which consisted of 16,228 maintenance records in the past ten years. This paper analyzed these data to obtain various characteristics of maintenance records, and revealed the key items of maintenance cost for large hospital buildings, which can provide the facility manager of hospital buildings to execute a proper maintenance policy for hospital buildings.

Purpose: This study proposes a process for evaluating the preventive maintenance policy for a system with degradation characteristics and for calculating the appropriate preventive maintenance cycle using time- and condition-based maintenance. Methods: First, the collected data is divided into the maintenance history lifetime and degradation lifetime, and analysis datasets are extracted through preprocessing. Particle filter algorithm is used to estimate the degradation lifetime from analysis datasets and prior information is obtained using LSE. The suitability and cost of the existing preventive maintenance policy are each evaluated based on the degradation lifetime and by using a minimum repair block replacement model of time-based maintenance. Results: The process is applied to the degradation of the reverse osmosis (RO) membrane in a seawater reverse osmosis (SWRO) plant to evaluate the existing preventive maintenance policy. Conclusion: This method can be used for facilities or systems that undergo degradation, which can be evaluated in terms of cost and time. The method is expected to be used in decision-making for devising the optimal preventive maintenance policy.

RCM developed by American air industry in early 1960, its process is most realistic for some physical assets and it permits the system to maintain given function status through decision of demand about optimum maintenance. Therefore, many industries have selected RCM technique and have carried out RCM in order to solve many problems concerning maintenance management as improvement of reliability and availability of facilities, removal of hazard element about break down and retrenchment of maintenance cost. Through the execution of RCM, we can solve actual problems. And finally we will be able to develop more and more maintenance activities with RCM notion. In this study, we will consider the application of KTX-RCM which is set up with basic theory of RCM and constructed to improve vehicle safety, availability and regularity of KTX, linking with CMMS(Computerized Maintenance Management System).

Present maintenance of a high speed railway is after the fack maintenance that executes a task when measured value goes over threshold value except some planned maintenance. It is difficult from efficient management of maintenance human resource and equipment commitment because it is difficult to predict quantity of maintenance targets. Corrective maintenance is pushed back on the repair priority of other target to need repair and it is exceeded repair cost potentially. For safety and dependable track management because track deterioration prediction is linked directly with track's life and safety of train service, it is very important that track management be based on preventive maintenance. In this study, we propose statistics model of track quality to use track inspection data and forecast model for track deterioration prediction.
