The necessity of urban regeneration is recently increasing because of the deterioration existing urban area and the slowdown of new development operations. The urban regeneration is differentiated from other private operations by its public characters, which is the basis of public support. This character demands verification of the adequacy for public finance support by monitoring urban regeneration planning and operation. Therefore, this study aims to show the monitoring indicators and its application in legal system for urban regeneration through the examination of foreign countries cases. London, San Francisco, and France urbanism regulation and planning system show the measure for introducing urban regeneration monitoring system into korean urbanism institution. This study is significant by suggesting the circulation structure of urban regeneration by linking planning, operations and monitoring phases. The monitoring system permits improvement of urban regeneration by clarifying objects and ameliorating efficiency by continuos observation and application of its evaluation.

The present study illustrates a method for monitoring the urban vegetation around Shaoxing city, Monitoring spatiotemporal changes in urban areas will become increasingly important as the number and proportion of urban residents continues to increase. The synoptic view of urban land cover provided by satellite and airborne sensors is an important complement to in situ measurements of physical, environmental and socioeconomic variables in urban settings. The results obtained have revealed a notable change in the vegetation cover in and around the City premises. In this study, we discussed methodology for measurement of urban vegetation and vegetation distributions based on band ratioing in Shaoxing city using Land sat TM imageries. A systematic analysis of the spatiotemporal dynamics of vegetation in urban areas is required to ensure a healthy sustainable environment.

본 연구는 도시철도에 의한 도시의 사회 및 공간적 영향을 개통 이후 지속적인 모니터링이 필요하다라는 측면에서 시작되었으며, 이에 본 연구는 대전시의 공간구조에 커다란 영향을 미칠 것으로 예측되고 있는 도시철도 1호선 개통에 따라 도시적 사회적 변화를 실증적으로 분석하고자 하였다. 이를 위해 학문적 고찰과 선행연구 고찰을 통해 도시철도가 도시에 미치는 영향을 예측하였고, 모니터링 지표를 설정하였다. 대전광역시 도시철도 1호선 역세권 지역에 대한 모니터링 결과, 인구와 토지이용, 총 개발연면적, 지가의 변화를 통해 도시철도의 개통이 대전시의 도시계획의 흐름과 도시공간구조의 변화에 영향을 미치는 것으로 판단되었다. 즉, 도시철도가 개통됨에 따라 도시철도 역세권 중심으로 인구 및 인구활동 등이 집중 되며, 인구 및 인구활동의 집중은 상업지역을 확대를 가져왔으며, 이러한 변화는 평균지가의 상승을 가져오는 결과를 초래하였다. 이처럼 도시모니터링은 도시의 전반적인 시기별 변화를 파악하는데 유용한 정보를 제공할 수 있으며, 현재 도시를 파악하는데 중요한 역할을 할 수 있음을 알 수 있었다.

One of the most important item for insuring the stability of ground in urban deep excavation site near by major structure such as subway is displacement control of earth retaining wall. The field monitoring system is classified by two types as manual system and automatic system. The application case of latter type of field monitoring is increased because real time measurement is possible in automatic system and that is correspondent with the recent constructional trend. Though the automatic monitoring system is more useful and advanced than manual monitoring system, accuracy of the system is not verified sufficiently. It was examined that the reliance of automatic monitoring system in this paper through the comparison of monitoring result obtained one of deep urban excavation site in which the each type of monitoring system was executed concurrently. Result of the examination is that the two types of monitoring system is generally alike in view of monitoring result, so the engineering reliance of automatic system was confirmed in case site. This study was researched in restricted one case site, so it is expected more precise analysis from security of more data monitored and progressive study.

The continuous monitoring of the runoff in the small-scaled urban watershed and easily accessible experiment catchment is necessary to investigate the overall status of the development in the urban catchment and the varying aspects of the discharge characteristics due to the urbanization. However, the research on the management and the characteristics of the small-scaled model basin for discharge tests has not been actively performed up to now. This study selects the Dong-Eui university basin, which locates at Gaya-dong in Busan, as the experiment catchment to monitor the discharge rate in the urban watershed. EMS(DEMS, DATA-PCS EMS, mini rain gage & AWS(AWS-DEU, DATA-PCS AWS) monitoring system installed for the collection of hydrological data such as the rainfall and the waterlevel. This experiment catchment is the typical urban catchment and is under development, and it is possible to analyze the varying aspects of the discharge rate during and after the development.

The CCTV, closed circuit television, system is the most popular method to monitor some specific area. The CCTV-based monitoring system is composed of a lot of cameras installed the areas, and monitors to display the vision through the cameras. However, these systems have limitations to prevent some problems or to cope with the problems promptly, because they can carry out only the function that shows us the analogue images of the cameras. Especially, urban transit service area is the space where many people crowd in all at the same time and the space is not only wide but also distributed sporadically. This paper presents the efficient plan for video-based monitoring system to monitor urban transit service area. To build the efficient monitoring system, it is necessary to devide the monitoring area to appropriate sectors that should be composed to be displayed at a time. If the proposed method is used to construct the video-based monitoring system, the operating officers in the urban transit have the more direct and real images.

This paper introduces an overall system design of a real-time monitoring system that monitors condition of urban railway AC/DC transformers, disconnecting switches, circuit breakers, regulators, and GIS (gas insulated switchgear). For effective diagnosis of urban railway facilities we developed optimized sensors and application technology. The proposed system is combined with wireless technology, implementing remote real-time monitoring of urban railway facilities. The derived real-time monitoring system for power facilities in urban railway substations will be applied not only to diagnose low voltage DC (direct current) railways but also to diagnose design of small power facilities of skyscrapers and apartments.

This paper presents the structural performance monitoring of an urban footbridge located in Hangzhou, China. The structural health monitoring (SHM) system is designed and implemented for the footbridge to monitor the structural responses of the footbridge and to ensure the structural safety during the period of operation. The monitoring data of stress and displacement measured by the fiber Bragg grating (FBG)-based sensors installed at the critical locations are used to analyze and assess the operation performance of the footbridge. A linear regression method is applied to separate the temperature effect from the stress monitoring data measured by the FBG-based strain sensors. In addition, the static vertical displacement of the footbridge measured by the FBG-based hydrostatic level gauges are presented and compared with the dynamic displacement remotely measured by a machine vision-based measurement system. Based on the examination of the monitored stress and displacement data, the structural safety evaluation is executed in combination with the defined condition index.
