A law and enforcement ordinance related to "ubiquitous city" (U-city) has been announced officially in Korea and practical standardization which is connected with U-city is in progress. The U-city defines citywide service over a city providing its infrastructure. The key facilities of U-city include intelligent equipments, networks, and operational facilities. Especially, the main focus of them is the intelligent equipments that are defined as facilities being applied to information technology. However, U-city has not been provided with standards related to actual construction of intelligent equipments so far. In this article, we survey standards for intelligent equipments for existing infrastructure and U-city's services.

In the process of urban development, the increase in the number and the complexity of urban facilities gives rise to a variety of problems, such as increase in construction and maintenance cost. In particular, taking into account the fact that an emergency situation in an urban facility can cause substantial loss of property as well as casualties, it becomes important to intelligently perceive states of facilities and properly execute countermeasures through real-time monitoring. In recent years, practitioners and researchers have made efforts to improve current passive and manpower-dependent facility management systems to be more active and intelligent, by applying diverse ubiquitous computing technologies for the u-City project. In this study, after discussing major drawbacks of the conventional facilities management, the concept and the model of a sensor-based integrated intelligent management system for urban facilities are proposed. The proposed model, by analyzing and processing real-time sensor data from urban facilities, not only supports the management of individual facilities, but also enables the detection of complex facility-related events and the process of their countermeasures. This active and intelligent management of urban facilities is expected to overcome the limitation of the conventional facilities management, and provide more suitable facility management services for the u-City development.

Nowadays, social environment is rapidly changed toward globalization and information age, and which demands the new paradigm for active utilization of information system in the field of education and many others. The effort to adapt tele-communication technique to educational facilities and the planning to make virtual university come true are needed immediately. Intelligent Building system should be applied to educational facilities to cope with the changing and progressing building system. As a result of the surveying eleven domestic universities, it was found that library management system, administration automation system and office automation system were already introduced, but campus infrastructure such as network system and tele-communication system between buildings in campus have been constructed now. As the conclusion of this study, impeding factors and improvement direction for active utilization of intelligent building systems in university facilities were presented.

U-City laws are divided into three categories: intellectual laws, information superhighway laws, and integrated operation center laws. Previous studies have suggested that efficient infrastructure operation and management is necessary in Ubiquitous-City (U-City). However, infrastructure is often interpreted differently by different laws. The purpose of this study was to plan for the integrated operation of intelligent service facilities by comprehensively analyzing the law system of domestic intelligent service facilities and problems in operation and management based on this critical mind. For this, present conditions and problems of intelligent service facilities were found through interviews with people who are in charge of the law system and other practitioners. The necessity of integrated use, including city information generated from intelligent service facilities and installment locations, has been demonstrated. Government ministries and local governments have established various information systems using ICT and U-City laws that specify integrated management and operation, but do not clearly specify definitions for the specific responsibility and authority for main agents participating in facility operation. A system is needed to smoothly mediate the relevant divisions so that they can use installed equipment simultaneously for efficient operation in generating city information. This objective of this study was to prepare a unitary law system for efficient installment and management of intelligent service facilities by establishing a logically linked relationship among the relevant laws and regulations. This will provide a foundation for a management system that has an integrated linkage of intelligent service facilities.

Intelligent distribution automation system have total monitoring and control capability. The system covers substation, distribution network, distributed generations and customers at HV system. Various intelligent distribution facilities installed at distribution systems have voltage sensor, current sensor, aging monitoring sensor. Intelligent Feeder Remote Terminal Unit (IFRTU) tied to intelligent distribution facilities process information from facilities and it checks information of fault, power quality and aging of distribution facilities. The information is transmitted to master station through communication line. The master station have remote monitoring system covers substation, distribution network, distributed generations and customers. It also have various application programs that maintain optimal network operation by using information from on-site devices.

The purpose of this study is to provide a sensor based service model for traffic facilities in u-City through analysing the present condition of urban infrastructure, especially traffic facilities management. In order to achieve this purpose, we did a comparative analysis of internal and external situation of ITS(Intelligent Transport System) and classified service for traffic facilities to 3 categories, namely traffic flow management, traffic information offering, formation of road structure. Also, we examined technological trend of USN(Ubiquitous Sensor Network). Through this process, we present a sensor based service model of traffic facilities for building sustainable road environment.

This study deals with the systematic classification and analysis of urban facilities as a fundamental foundation of the intelligent and active management of urban facilities using Ubiquitous Sensor Network(USN). In the results of recent studies, the necessities and simple examples of USN application were already shown, but there were few studies about the systematic classification and specific application methods considering characteristics of urban facilities. In this study, we try to classify the main management characteristics of facilities and analyze the results, furthermore to contribute to the development of convergence of facility management and USN technology.

The objective of this project is to construct the intelligent underground facility management system based on UFSN (Underground Facility Sensor Network). Total project duration is 6-year. And first two years' project has been finished. First two years' project focused on water supply and sewage facilities among 7 underground facilities and investigated the fundamental construction technology for the underground facilities management system. To contribute the development of systematic and scientific management of underground facilities, KRIHS implemented 3 researches for 'Underground facilities management system for an intelligent city' like followings: (1) to investigate an integration plan for current water supply and sewage management systems, (2) to derivate of water supply and sewage monitoring items for the monitoring technology development, and (3) to implement a basic research for sensor installation plans on different types of current and new underground facility systems.
