최근 도시화가 급격히 진행되면서 도심 공간의 효율적인 이용을 위하여 지하공간의 개발이 새로운 대안으로 주목 받고 있다. 지하공간은 일반적으로 건축 구조상 자연채광의 유입이 불가능한 구조로서 지하 거주자의 심리적, 환경적 문제를 초래하므로 이의 활성화를 위해서는 공간의 질적 제고가 선행되어야 한다. 빛과 조명은 공간의 질을 결정하는 중요한 요소로서 거주자를 위해 건강하고 편안한 환경을 제공하기 위해서는 거주자의 생체리듬과 부합하는 자연광과 유사한 광 환경(색온도, 조도) 서비스를 제공해야 한다. 본 논문은 지하공간을 대상으로 인공조명의 광 환경을 시간의 흐름에 따라 변화하는 자연의 빛과 유사하게 서비스하기 위한 LED제어시스템을 개발한다.

With development of the earth's subsurface space, the need for a reliable subsurface spatial model such as a cross-section, boring log is increasing. However, the ground mass was essentially uncertain. To generate model was uncertain because of the shortage of data and the absence of geotechnical interpretation standard(non-statistical uncertainty) as well as field environment variables(statistical uncertainty). Therefore, the current interpretation of the data and the generation of the model were accomplished by a highly trained experts. In this study, a geotechnical ontology model was developed using the current expert experience and knowledge, and the information content was calculated in the ontology hierarchy. After the relative distance between the information contents in the ontology model was combined with the distance between cluster centers, a cluster analysis that considered the geotechnical semantics was performed. In a comparative test of the proposed method, k-means method, and expert's interpretation, the proposed method is most similar to expert's interpretation, and can be 3D-GIS visualization through easily handling massive data. We expect that the proposed method is able to generate the more reasonable subsurface spatial information model without geotechnical experts' help.

수재해의 증가로 인한 지하차도 침수 사고가 빈번히 발생하고 있다. 지하차도 침수 사고를 예방하기 위한 여러 대비책들이 있지만, 예방적 관점에서 볼 때 사람이 직접 모니터링 하는 방법 이외에는 적절한 예방책이 되지 못한다. 이러한 문제를 해결하기 위해 강수량에 따른 지하차도 진입 여부 시스템을 제안한다. 강수량과 배수량의 차이를 통해 침수 위험도를 판단하여 진입 여부를 파악 후 운전자에게 정보를 전달해 사고를 예방할 수 있다.

"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.

With the promotion of the u-City project in recent years, the need for the systematic and efficient management of ground and underground facilities comprising the urban infrastructure has been increased. Considering that the diverse services provided in the u-City are closely related to the physical environment of the city itself, including its location and condition, the core of such management must be to continuously maintain these facilities in a normal state, based on accurate data collection from the facilities. This paper discusses a method of collecting the sensor and the object data that are needed to accurately understand the state of the underground facilities, and presents a plan to build an Underground Facility Management System on this basis. This plan is then verified using a scenario test performed by a prototype system.

In this study, the disaster management and disaster medical improvement was described in underground space(specifically underground shopping center) in case of fire disaster occurred. Firstly, statue and system was discussed concerning building law, safety, fire services, refuge. The underground in Seoul management is classified as to space and form and management agent is different according to the type form. Because the difficulty of emergency rescue arises due to individual management system unified system needs to be established and improvement of facility management agent is necessary. For the patient to be transfer on the ground, corporation between command head quarter and emergency rescue team are essential. And disaster information and emergency medical information are also need to be considered. Therefore, effective countermeasures for emergency saving is urgent considering distribution of medical institution and medical treatment.

In this study, for the integrated information management of underground pipelines, each information management server software must have it's inter-operability. So Many kinds of smart-city integrated platform softwares were surveyed and the best platform software was selected. The interface software modules developed in this study was installed at the test system. Through this test system, when a sub system transfers an event message to the upper integrated server system, the inter-operability test between the upper system and a sub operating system was performed and its operability was resolved.

In order to develop a spatial information system that can efficiently manage various subsurface data and produce information in a proper form for a user, we established a database of the well cores and built 3-D shapes that visualize the subsurface objects such as wells, ore bodies, tunnels, and mine cavities. We also made analysis tools available for three-dimensional ore bodies constructed here, such as vertical cross-section generator and mass computing tool. This system was developed by coding Avenue, a scripting language incorporated in ArcView, which is a commercial GIS software. Using the system, it is expected that users can make fast and accurate analysis and interpretation through real-time queries and by contemplating various objects in 3-D perspective.

Due to recent underground space accidents, are a frequent occurence in Korea, the government established the basic plan for the construction of the IUGIM (Integrated Underground Geospatial Information Map) in 2015 as a measure for safety management of underground spaces. The development of IUGIM was partially completed as of 2021. The underground space management entity and related organizations are utilizing it. This study is being carried out as part of a plan to improve the usability of IUGIM, and to build a visualization system that compares real-time field data with stored data. A system, equipped with a visualization function for borehole data and 6 types of underground facilities built and managed on IUGIM; a tool capable of comparative analysis with real-time data measured in the field, is being built. The 6 types of underground facilities are water supply pipe, sewage pipe, power pipe, gas pipe, communication pipe, and heating pipe. The completed system was demonstrated at three locations in Seocho-gu, Gangnam-gu in Seoul. The field demonstration was carried out by accessing the mobile center and downloading IUGIM data, visualizing IUGIM data (surface creation, borehole information, underground facilities), and visualizing the GPR(Ground Penetrating Radar)-based data acquired at the field. As a result of the empirical results of IUGIM data and GPR-based field data, it was judged to be suitable. As a result of this study, it is judged that it can be helpful for safe construction at the excavation site.
