The function failure of present major facilities is likely to lead to failure of related systems and/or whole facilities, increasing the necessity for protection of infrastructures, main structures, and major industrial facilities. In addition, safe and efficient management for urban infrastructure (waterworks and sewerage facilities, electricity, telecommunications, roads, etc) installed in the basement or on large cities grounds at various public areas is required. Recently in response to this demand, efforts for vitalizing asset management are being made such as enacting related laws and developing asset management system in the U.S., Australia, Europe and other advanced countries with the concept for a new maintenance. In our county, identifying maintenance system problems such as aging and rapid increasing of existing infrastructures and decision-making about updating maintenance is required for systematic and organizational maintenance. In this study, by comparing and observing the LOS(Level of Service) of each countries' waterworks and risk-based LOS, we suggest the direction of future urban water infrastructure management systems for more effective management.

The aims of this study is to find the facts of regional inequality and to suggest the desirable location of educational facilities and its related policies through the analysis of the distributional characteristics of high schools in Daegu viewing from public service facilities. The results are as follows. As of 2000 year, there are 76 high schools in operation in Daegu. The number of private high schools is more than that of national public ones in terms of their founders, and the number of general high schools outnumbers that of vocational high schools by their operational types. As a whole, the distribution of schools in Daegu is closely related to the population distribution(redistribution). In case of high schools, it shows that there is severe unevenness between demand and supply of educational facilities per district. The regional inequality of school facilities is getting worse by transfer and new establishment; inter-district transfer is mainly caused by the redistribution of population while intra-district transfer is accelerated by the pressure on better use of land. Recently there is a tendency that schools are newly established by public sector(national public schools) rather than by private sector(private schools). And the predilection or avoidance of a certain area in the process of choosing the site for transfer or new establishment of schools lead to inequality of education opportunities per district. In conclusion, the educational facilities should firstly be placed in the practice of public service facilities in terms of public welfare as well as the convenience of residents and regional inequality. Consequently, both construction of new high schools and the relocation of existing high schools have to be further activated. To achieve them, the role of public actions is particularly more important than that of private ones.

University dorm basically provides basic housing functions to students, however, it is very important in a sense that it provides students with various functions such as information exchange, cultural experience and learning environments as well. Additionally, continuous effort to improve users' satisfaction and living environments are needed due to the fact that physical environments of dorm facilities have higher impact on students. However, Many students are not satisfied with the physical environment of university dorms and also there is lack of systematic information whereas various functions are required by students. Therefore, the main objective of this research is to suggest the direction of FM services in order for improving students' satisfaction on the university dorm facilities in Korea. Precedent studies regarding the satisfaction or performance evaluation of dorm facilities have been extensively analyzed to extract the dissatisfaction factors that scored below the middle 50%. Secondly, for satisfaction improvement, Korean Standard for Facility Management(KS_FM) have been matched with those extracted dissatisfaction factors to suggest the direction of FM services by rules and regulations review and best practice studies. This research will be useful for university dorm facility managers in planning strategic FM and providing effective FM services to students.

There are customer services jointly provided by two facilities so that each customer will complete the course made up of both facilities' sub-services. The two facilities are assumed invested respectively by an infrastructure owner and one subordinate facility owner, whose partnership is built on their capital investments. This paper presents a mathematical model of Stackelberg competition between the two facility owners to derive their optimal Nash equilibrium. In this study, each facility owner's profit is consisted of fixed revenue fractions of sold services, operating costs (including depreciation cost) and maintenance costs of her facility. The maintenance costs of one facility are incurred both by failures and deterioration due to usage. Moreover, for both facilities, failures are rectified immediately by minimal repairs and preventive maintenance is carried out at a fixed time epoch. Additional assumptions are also employed to develop the model such as customer arrivals are manipulated to follow a Poisson process, and each facility's lifetime is independently Weibull-distributed. The Stackelberg game proceeds as follows. At the first stage of decision making process, the infrastructure owner (acting as a leader) decides the allocation of revenue shares based on her self-interest. After observing the allocation of revenue shares, the subordinate facility owner determines her own optimal price of services. This paper investigates actions and reactions of the two partners in the system. Then analytical conditions are proposed to achieve a unique optimal Nash equilibrium. Finally, some suggestions for further research are discussed.

Recently, the welfare of the elderly and the disabled has been becoming more important. For this reason, many facilities to accommodate them are being constructed in government and public offices. However, the facilities are usually just installed without providing information to the elderly and the disabled. So they are still faced with many difficulties due to the insufficient information on these new facilities. In this study, we implemented the information system of facilities which provides information to the elderly and the disabled through web pages. The objective of this system is to provide visual information about facilities. This system uses web service technology for effective management of data. It is being offered in Incheon's local office. Also, we see a high level of system satisfaction via a survey.

Purpose: The first thing to be done in promoting community care is local diagnosis. Therefore, this study attempted to derive the physical infrastructure to be diagnosed, and to develop diagnostic items and diagnostic indicators applicable to this. Methods:: First, the physical infrastructure related to the community care is derived. And the diagnosis items are derived using the checklist of 'community support and health services' in the WHO Guide for Global age-friendly cities. Next, by analyzing previous studies, we develop diagnostic indicators for each diagnostic item and explore their applicability. Results: As a result of deriving the physical infrastructure for each area of housing, health service, and nursing care for community care, 22 facilities were derived for 9 types. Diagnosis items for the facilities are 1)regional equity, 2)proximity between facilities, 3)transportation access, 4)regional use, 5)barrier-free design, 6)diversity of facilities, and a total of 14 diagnostic indicators was derived. We reviewed and suggested the applicability of diagnostic items and indicators by each physical infrastructure. Implications: For the realization of community care, local diagnosis should not be limited to sim- ply grasping the presence or absence of facilities and the total amount. Instead it should strengthen capabilities by conducting diagnosis to understand the performance of facilities.

This study was conducted to evaluate microorganism contamination of food utensils and service facilities in school and to prevent hazards by food poisoning occurrence. As a result, the highest number of microorganism growth plate ($12.3{\pm}2.6$) was detected in total bacteria test plate, and also observed $10.3{\pm}3.9$ growth plates in Staphylococcus aureus test plate and $9.5{\pm}3.9$ growth plates in E. coli and coliform bacteria test plate. But we could detect to the lowest number of growth plates ($1.5{\pm}1.0$) in Vibrio test plate. We also assessed that floors were appeared to the highest microorganism contamination rate in food utensils and service facilities. Therefore, $4.5{\pm}0.6$ growth plates was detected in pre-operation floor and $4.3{\pm}1.0$ growth plates in floor. And high level of microorganism contamination also observed in tables as $3.3{\pm}1.0$ growth plates in cooking table and $3.0{\pm}0.0$ growth plates in dining table. The level of microorganism contamination of food utensils such as kitchen knife, cutting board, and food tray were lower than that in food service facilities. We analysed microorganism contamination according to purpose of use in kitchen knifes and cutting boards. The microorganism contamination rate in fish kitchen knife ($2.0{\pm}0.8$) and fish cutting board ($1.3{\pm}1.5$) were slightly higher than that of others purpose of use. As a result of microorganism identification, various strains of microorganism were contaminated in food service facilities and some strains could detected more than two times. Especially, Staphylococcus aureus was repeatedly identified in cooking table, trench, and kitchen knife. Bacillus cereus was identified in kitchen knife, and then Pseudomonas fluorescens and Pseudomonas aeruginosa were also detected in food utensils and service facilities as known to food spoilage microorganisms. Klebsiella pneumoniae was detected four times repeat, which widely distribute natural environment as normal bacterial flora but sometimes cause acute pneumonia. These results suggest that food utensils and service facilities are contaminated with not only major food poisoning microorganisms such as Staphylococcus aureus, but also food spoilage microorganisms. Taken together, strict personal hygiene control and efficient food service facilities management will be needed to enhance food safety in school feeding and to improve student health.
