This paper is designed to find and develop new concepts for the sustainable traditional village in Korea. To this end, it is necessary that concern for the traditional village should diversify and expand, and not concentrate solely on the cultural properties and architecture-oriented historic elements. In consideration of this notion, this paper suggests introduction of maintenance and management as a practical concept for the embodiment of the sustainable traditional village. This paper aims to explore the concrete maintenance and management systems of Korean and Japanese cases, to analyze differences and characteristics between the two nation\\\\`s, and through these comparisons, to suggest sustainable maintenance and management methods for the traditional village in Korea. Primary data was collected by field and interview survey on each village in the two nations several times during about a two year period. The major findings of this paper are presented in three categories--maintenance management frame, maintenance management contents, and necessary principles for progressive maintenance management, and are as follows; In the first step, suggests the basic directions, boundaries, and systems for the maintenance and management of sustainable traditional villages. And in the second step, analyzes the relationship among the contents of maintenance and management methods with focus on the village space, village attraction, and village community. Our results suggests diverse maintenance and management contents for the sustainable village maintenance and management. Finally, the basic principles for the application, and use as valuable tools for sustainable village maintenance and management, are strongly recommended.

A robust asset management methodology is essential for effective decision-making of maintenance, repair and rehabilitation of a bridge network. It can be achieved by a computer-based bridge management system (BMS). Successful BMS development requires a reliable bridge deterioration model, which is the most crucial component in a BMS, and an optimal management philosophy. The maintenance optimization methodology proposed in this paper is developed for a small bridge network with limited structural condition rating records. . The methodology is organized in three major components: (1) bridge health index (BHI); (2) maintenance and budget optimization; and (3) reliable Artificial Intelligence (AI) based bridge deterioration model. The outcomes of the paper will help to identify BMS implementation problems and to provide appropriate solutions for managing small bridge networks.

PURPOSES : This study aims at proposing the methodology for benefit evaluations in pavement maintenance methods and timings using KoPMS(Korean Pavement Management System) software which was developed for efficient pavement management. METHODS : This study classified pavement sections into 4 clusters considering AADT(Annual Average Daily Traffic) and ESAL(Equivalent Single-Axle Load) using cluster analysis and used the deterioration models in each cluster. Increased user costs due to pavement deterioration as time goes by and agent costs for maintenance were estimated. Based on deterioration model and KoPMS software, Methodology for benefit evaluation was proposed in pavement maintenance methods and with/without implementation using real pavement section data. RESULTS : This study verified that considering agent costs only would be constrained to decide pavement maintenance methods and timings, and ascertained that decision making with agent and user costs would be effective. In addition, this study revealed that pavement maintenance methods and timings can be affected by AADT and ESAL and frequent pavement maintenances can be more efficient for benefits in pavement sections with more AADT and ESAL. Also this study found that user costs would be more affected to decision making than agent costs. Moreover, Delay of conducting pavement maintenance caused increased vehicle operating costs and environmental costs because of poor conditions of pavements. CONCLUSIONS : This study proposed LCCA and benefit estimation methodology of pavement with considering agent and user costs. The results of this study can be used for baseline data of efficient pavement asset management.

In Factory, as the number of machine is increased the more maintenance efforts are necessary. Multi maintenance issues may occur at a certain time and the determination of maintenance sequence is needed. In this study, we first compare the priority of machines and the impact value using modified FMEA(Failure Mode Effect and Analysis) method. Also, CBR(Case-based Reasoning) approach is applied to retrieve similar fault cases of current machine problem. The proposed methodology will be useful to implement decision support system of maintenance sequence for CMMS/EAM (Computerized Maintenance Management System/Enterprise Asset Management).

Purpose: This study discusses efficient operation plans in terms of public rental housing maintenance in terms of LH, a major supplier. Research design, data, and methodology: After reviewing problems related to the maintenance and management of public rental housing discussed in several previous studies, problems in technology setting for repair maintenance costs for public rental housing, lack of public assistance for maintenance and management of public rental housing, management of housing funds, and lack of role of local governments in the supply and repair of public rental housing were derived. Based on this, the researcher conducted using literature research methods to present relevant improvement measures based on reasonable arguments. Results: this study presented four operational plans related to (1) realization of repair costs for public rental housing, (2) a public subsidy system for covering the maintenance costs for public rental housing, (3) efficient operation of the Housing City Fund, and (4) establishment of the public rental housing. This study aims to provide a foundation for the qualitative growth of the domestic public rental housing system. Conclusions: With this study, it is expected that social interest in maintenance of public rental housing centered on LH will be amplified to improve the quality of maintenance problems of public rental housing.

Recently the study related to life cycle cost analysis of railway structure consisted of a complex is proceeded covering several range, which is considering the methodology of efficiency and rationalization for maintenance and analysing long-time behavior of the structure of looking at standpoint from asset management and safety. But LCCA(life cycle cost analysis) of railway structure was almost impossible as there were not anything datum for maintenance plan, such as maintenance periods related to each of components(painting and corrosion of steel, and cracking of elements, etc)and maintenance proportion, despite of its 100-year history. According, for collecting data related to railway truss bridge, bridge record cards and testing safety papers, and researching question, etc are surveyed and classified for LCC Analysis. Especially, LCC assessment on the side of assets-maintenance considering about initial cost, maintenance cost, and indirect cost is constructed. Maintenance period and complementary measure rate are very important in maintenance. To decide maintenance period, Baysian updating method is applied.

An efficient cost management is important for the domestic social overhead capital(SOC) based on a long lifecycle after 30 years since completion. Maintenance in South Korea have had the restrictions of consistency and suitability of decision-making by the establishment of a budget plan based on the company estimate and repair and reinforcement methods determined by the inspection and diagnosis engineers' subjective determination for each facility. To resolve this issue, the Korea Institute of Civil Engineering and Building Technology is currently in development of a methodology to propose an optimum maintenance method according to the damage of components by artificial intelligence. This study has deduced the primary factors by analyzing information generated during bridge maintenance and management as a prior step for the development of technologies, and conducted a preliminary analysis to select the optimum artificial intelligence technology.
