The population is increased in the area of a subway station because the accessibility of passengers is improved. Therefore, facilities for commercial purpose are concentrated in this area. To develop the station area as the center among the most urbanized area, overall mater plan should be constructed far the station area. This study was to construct web server for management a variety of 3D spatial object database of station areas using GIS and web 3D technology. These results will be used to manage efficiently a urban space by the connection of a subway station and a adjacent facilities.

With the rapid development of cites, urban facilities have rapidly been increasing, and the task of managing them have also become complicated more and more. In this paper, we propose and design an intelligent context awareness system that effectively operates underground facilities in u-City. The suggested system consists of three major steps. The information acquisition step receives alarm information of sensors from the integrated platform. The analysis and inference step analyzes the alarm data and related information and infers the reason why the alarm happens. The information transmission step sends the final results of context awareness to the platform and other related modules. We produced some design products such as data flow diagram, function diagram, etc. We expect that the proposed context awareness system will be embedded in the integrated platform and used for an active management strategy of urban facilities.

As nation and society progresses, urban ground facilities and their management system get more complicated and the cost and effort to control the system efficiently grows exponentially. This study suggests to the deployment method of a sensor node by Wireless Sensor Network for controling the Urban Ground Facilities of National Facilities. First, we achieve the management facilities and method using the first analysis and then make the coverage of sensing and then set up the Sensor Node in Urban Ground Facilities. Second, we propose the solution way of repetition by the second analysis. And, we embody the GIS program by Digital Map and this method, we improve the reality by overlapping an aerial photo. Also we make an experience on the sensor node allocation using making program. we can remove the repetition sensor node about 50%, and we can confirm that the sensor nodes are evenly distributed on the road.

A solar power plant is a facility that produces electricity. As the risk of fire and electric shock accidents is diversified, the risk of workers, surrounding people, and facilities is increased, preventing safety accidents and promptly responding to safety accidents Is emerging. In light of the necessity of such development, it is necessary to develop a solar power generation management system that can diagnose and maintain the problems of the power generation system in real time by developing technologies for collecting and analyzing the data produced by the solar power generation system As a result, the utilization rate and the maintenance cost can be reduced. In order to do this, it is necessary to accurately predict the solar power generation amount in the present state, to diagnose the abnormality of the current power generation state and to grasp the abnormal position, and to use the model considering economical efficiency when the abnormal position is grasped, And the time and other information should be provided.

This study carried out structural behaviors and power generation performances of customized energy harvesting block structures, especially for infrastructures such as parking facility. The improved energy block structures described in this study were represented by using numerical and experimental models. In particular, the composite-PZT hybrid energy blocks are tentatively proposed for better structural durability and power generation effects. The finite element model using ABAQUS program is used for studying static and dynamic characteristics of block structures made of composite materials. In addition, we evaluated the various power generation capacities of advanced energy block structures through laboratory-scale and field experiments.

In Korea, much effort is being made to introduce asset management for improved efficiency and lower costs. Many researches related to asset management are ongoing, but asset management for public facilities is still in its early development stage in many countries including Korea. It is necessary to continuously improve and complement asset management for its successful execution. Thus, there should be a series of performance measurements and evaluations to perceive the current state of asset management in Korea from which to set future goals. In developed countries including Australia, asset management performance is measured using various methods for diverse purposes. The Korea Institute of Construction Technology has recently launched a study entitled Development of an Asset Management System for Public Facilities (KTAM-40) to change the country’s existing countermeasure-type maintenance system into a preliminary maintenance system and to suggest asset management evaluation parameters. this study aims to develop performance indicators of effective asset management with respect to its utility, which shall include all matters that are important for the efficient measurement of the management of domestic public facilities using the BSC (Balanced Score Card) method, and AHP method.

In many developed countries, social infrastructure asset management has become an important issue for the effective operation and management, performance improvement, and providing better quality services. This paper describes infrastructure asset management practices in Korea and in the developed countries. Learning lessons from those countries and improve the asset management practices in Korea is the main theme of this paper. Considering the definition and basic structure of infrastructure asset management, authors have analyzed main concerns regarding infrastructure management, techniques, organizations (systems), and processes. The requirements and considerations are presented to overcome the limitations of current maintenance system. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.
