Domestic maintenance strategies are shifting from safety assessment to performance assessment, and related systems and laws are being restructured to meet those criteria. In order to introduce asset management based on performance evaluation, related evaluation methods such as performance measures and level of service should be made to evaluate performance according to the characteristics of the structure, but these are not well-prepared in Korea. In this study, we present a computerized model and system for implementing asset management that introduces techniques such as performance evaluation, life cycle cost analysis, performance measures, and level of service in conjunction with existing maintenance and safety diagnosis procedures. The features of this system consist of three modules to enable separate operations of existing maintenance, safety management and asset management. The system is designed to be used as a reference for public institutions to introduce asset management in the future.

The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

The marine transport industry generally applies new technologies later than other transport industries, such as airways and railways. Vessels require efficient operation, and their performance and lifespan depend on the level of maintenance and management. Many studies have shown that corrective maintenance (CM) and time-based maintenance (TBM) have restrictions with respect to enabling efficient maintenance of workload and cost to improve operational efficiency. Predictive maintenance (PdM) is an advanced technology that allows monitoring the condition and performance of a target machine to predict its time of failure and helps maintain the key machinery in optimal working conditions at all times. This study presents the development of a marine predictive maintenance (MPdM; maritime predictive maintenance) method based on applying PdM to the marine environment. The MPdM scheme is designed by considering the special environment of the marine transport industry and the extreme marine conditions. Further, results of the study elaborates upon the concept of MPdM and its necessity to advancing marine transportation in the future.

A battle management system should be introduced to improve mission success capabilities and accommodate integrated combat capabilities through increasing SA(Situation Awareness), or spatiotemporal synchronization of military operation in battle field environment. Conventional Korean Main Battle Tanks(Korean MBTs), which have been operated without digital network, were developed for 1980s. Korean new MBTs, which are mounted the battle management system, will be fielded soon. Therefore, old Korean MBT is needed to improve performances for co-operation with new one. This paper is reviewed each improved MBTs of world countries and domestic maintenance facilities. And this study suggests some processing methods which might be applicable to improve information network performance of old Korean MBTs.

Life-cycle performance and maintaining cost predictions are required for the effective management for bridges. In Korea, the importance of management of bridges has been recognized over the past two decades, resulting in the development of databases and various bridge management support tools by both government and private sectors. However, none of these tools has truly included the expected features of the bridge management system (EMS) for the next generation such as the quantification of the effects of maintenance interventions on bridge condition and safety. In this paper, a novel quantification process to simulate the life-cycle performance of steel box bridges has been developed. The process is based on the Response Surface method. Various performance-related variables aloe investigated to identify a set of significant design variables to construct the response surfaces.

Inter-floor noise in an apartment building is a serious problem that causes conflicts between tenants. Accordingly, there are various attempts to solve this problem, but it is not easy to find a clear solution. Therefore, in this study, a soundproofing material between floors was developed that can improve the sagging that occurs after construction. And as a result of testing the developed interlayer soundproofing material, both light weight and weight were grade 1. And it was analyzed that maintenance performance could be improved with integrated structural characteristics.
