The number of damaged lifeline structures have been increasing with urban acceleration under earthquakes. To predict the damage, damage mitigation technology of lifeline structures should be analyzed using damage prediction technology. Therefore, in this paper, the degree of the fragility of structures under an earthquake was evaluated stochastically through an evaluation of the seismic fragility. The aim was to develop damage prediction technology of sewage pipes among the lifeline facilities. The site response was performed using the data from 158 boreholes in Seoul and 7 real earthquake waves to determine the responses in real urban areas. The seismic fragility was deduced through a total of 29822 time history analysis. In addition, sewer pipes were evaluated and the persisting period was passed by applying the research results of strength reduction which is due to sulphate erosion. As a result, the difference in failure probability between 300 and 800 with the smaller diameter of the representative pipes was approximately double and the size of the pipes has a significant effect on the seismic fragility function. Moreover, the failure probability of a seismic load increases by up to 10 fold as the strength reduction rate increases. The results of this study can be used as a means of predicting the damage and countermeasures of sewer pipes and might be reflected in the seismic design of underground facilities.

Local governments began to construct geographic information system to improve government productivity and performance. In support, central government organized a national commission for GIS. The master plan by NGIS has been the base for local government to participate in the construction of GIS at the local level in the under ground facilities management including water and sewers. The challenge faced by sewer facility managers includes controlling 'data accuracy'. The input for sewer data handling for efficient performance in local government requires accurate data. However data manipulation to get the 'good quality' data can be burdensome. Thus, the aim of this research is to provide the appropriate tool to guarantee the high quality of digital data in sewer facility management. It is helpful to pass the data examination by government as well as to insure confidence of decision and data analysis works in local government. In this research, error types of sewer data were classified and pointed the limitation of traditional examination methods. Thus this research suggested more improved method for finding and correcting errors in data input using sewer volume analysis and prediction model as immigrating sewer facility management work to Geographic Information System.

It is one of the most crutial thing to secure efficient infrastructure of social infrastructure Including rna drinking water, sewer, gas, and electricity, etc. in modern society. Among them, the sourer system need to be properly maintained so as to sustain water quality over the large watershed thereby to provide reasonable level of living environment A few municipalities and private firms have so in been using sewer management system for assessing existing sewer network and auxiliary facilities. Such existing system can only provide functions to manage the sewer pipe itself and they can not fully estimate the amount of sewage water over the pipe through 4he network analysis due to the deficiency of the system Such a limited sewer network analysis function can only analyze the whole network under the assumption of uniformity. The results from such a process can not be fully implemented in the field. Therefore, this study emphasized the development of a sewer management system which can provide practical values from network analysts considering areal peculiarities using a zoning map utilizing a GIS. The system can support analyzing scenarios due to the changes of sewer amounts from the changes of population densities and rainfall amounts not to mention of calculating sewer amount for individual sewer pipes. furthermore, the system can support the decision making for better designing sewer facilities from the expansion of metropolitan areas and constructing satellite cities. Eventually, it will contribute to enhance the effectiveness of sewer-related works and services for residents as well as supporting a decision making for minor and major trouble-shootings.

Integrated Urban Spatial Information Management Platform (USIMP) is defined as an operational environment where technologies for intelligent management of urban facilities are made possible through the integration of diverse technologies such as sensors for ground and underground facilities, middleware technology, wired and wireless network, GIS-USN linkage. To make the integration of these diverse technology possible, it is imperative to have a sound reference model for the platform. This paper provides a standardized reference model for USIMP based on the RM-OPD(Reference Model for Open Distributed Processing) standard.

하수관거정비 전 후에 문제관을 판별하고 원인분석에 사용되어지는 불명수 산정방법이 대상유역을 평균적으로 분석하는 방법을 주로 사용하고 있고 이러한 분석방법조차 정확히 어느 정도 실제 불명수 발생량과 일치하는지에 대한 연구도 미비한 실정으로 분석방법의 적용성에 대한 평가가 시급한 상태이다. 본 연구에서는 직접측정이 가능한 대상유역내에서 직접측정과 기존 문헌상 제시되어 있는 침입수/유입수 분석방법(물사용량 평가방법, 일 최대 침입수량 평가방법, 최대-최소 유량 평가방법, 야간 활동인구 사용수량 평가방법, 일 평균 최저유량-수질 평가방법)을 사용하여 하수관거내 I/I량을 산정하였으며, 동일 기간내 실제 현장의 I/I량을 산정하여 비교하였다. 대상지역은 H시로 조사지점은 사전답사 후 6개의 직접측정지점을 선정하고 소유역의 하단에는 유량계를 사용하였으며, 본 조사지역의 주변에 공장이나 물사용량이 많은 시설물은 없었으며 따라서 야간에는 하수발생량이 적게 발생되고, 보다 정확한 조사를 위하여 유량이 거의 발생하지 않는 새벽시간에 직접측정을 실시하였다. 조사기간은 2007년 10월29일부터 11월13일까지 측정하였고 수질의 경우 11월3일과 6일의 평균 채수 값을 사용하였다. 본 연구를 수행한 결과 본 연구의 대상지역인 주거지역이 밀집된 경우 야간생활하수량이 적용되는 야간 생활 하수평가기법이 가장 합리적인 것으로 분석 되었다.

It is very important entity that a map of urban facility is in civic life and development of city. But now, there are many needs of computerization which was used for management of urban facility map because inefficiency was produced due to management of urban facility map by hand. This paper, it was showed that a processing of establishing database in computer by applying GIS. The used sample area in studying in Ansan city in Kyunggi province and a sewer pipe which was in there adapted to establish database in computer. A map of administration district, which is 1:38,000, a map of complex urban planning of city, which is 1:3,000, and the facility map were used for the input of spatial data and the address, the year when sewer pipe was burried, and the quality of pipe, the pipe diameter, and the length of pipe were used as attribute data. Relational structure was used for establishment of database then, searching, analyzing, and processing were possible. Additionary, the result of this studying can be used for replacement of a old sewer pipe, a material quantity which is related with repairement of sewer pipe, and calculation of time, cost by application program framed by Fortran.

Recently, ground subsidence has been continuously occurring in downtown areas, threatening the safety of citizens. Various underground facilities such as water and sewage pipelines and communication pipelines are buried under the road. It is reported that the cause of ground subsidence is the deterioration of various facilities and the reckless development of the underground. In particular, it is known that the biggest cause of ground subsidence is the aging of sewage pipelines. As an existing study related to this, several representative factors of sewage pipelines were selected and a study to predict the risk of ground subsidence through statistical analysis has been conducted. In this study, a data SET was constructed using the characteristics of OO city's sewage pipe characteristics and ground subsidence data, The data set constructed from the characteristics of the sewage pipe of OO city and the location of the ground subsidence was used. The goal of this study was to present a classification model for the occurrence of ground subsidence according to the characteristics of sewage pipes through machine learning. In addition, the importance of each sewage pipe characteristic affecting the ground subsidence was calculated.

"GIS가 만들어지면 행정 및 국가전략기획, 사회조사 계획 등을 효율적으로 추진할 수 있다. 예를 들어 대구지역의 도시계획을 입안할 경우 지하철, 전화선, 전기배선망, 상.하수도, 도시가스 등을 한눈에 보면서 종합적인 일정을 마련할 수 있다. 대구시에서 구단위 동단위를 확대하면 불과 1cm 단위의 거리에 위치한 정보까지도 검색할 수 있다. 이 시스템이 진작 만들어졌다면 이번 대구 대형참사를 사전에 예방할 수 도 있었을 것이다." 이는 대구지하철공사장 가스폭발사고가 발생한 후 어느 신문에 게재된 기사중의 일부이다. 이 사고를 바라다보는 대부분의 전문가들은 GIS를 구축해야 한다고 말했다. 어떻게 들으면 GIS가 구축되지 않아 이러한 사고가 발생했다고 하는 말과 같이도 들린다. 이 기사는 사실 틀린 말이 아니라고 생각한다. 그러나 이 기사내용을 찜찜한 마음으로 쉽게 받아들일 수 없는 'GIS가 만들어지면'이라는 말 때문이다. 이런 찜찜한 마음이 어디에서 오는 것일까? 여기에서는 우리나라에서 지리정보시스템을 이용하여 도시지하시설물 관리체계를 구축하는데 어떤 문제가 있고, 지리정보시스템이 도시지하시설물 관리에 어떤 역할을 할 수 있는가를 살펴보고자 한다.
