최근 도시화된 지역의 지하개발로 인한 각종 문제가 증가함에 따라 정확한 지하시설물 정보관리가 요구되고 있다. 이에 본 연구에서는 현장에서 실시간으로 지하공간통합지도를 활용하기 위해 현장 취득 GPR (Ground Penetration Radar) 탐사 데이터와 지하공간통합지도의 상호 위치를 비교하는 기능, 지하시설물 분석 기능, GPR 탐사 단면을 지하공간통합지도 상에 중첩하여 가시화 하는 기능, 측량 데이터를 3차원 공간상에 정위치 및 속성 편집을 통해 셰이프 파일로 변환하는 기능, 셰이프파일을 지하공간통합지도 모바일 센터에 제출하는 기능을 정의하여 프로그램으로 개발하였다. 또한, 개발 프로그램의 현장 적용 테스트를 위해 상수관로 매설 공사 현장에서 지하시설물 실시간 측량 현장에서 활용하는 시나리오와 GPR 탐사 현장에서 활용하는 시나리오를 도출하였으며, 서울시 관내 4개소에서 현장 실증을 수행하여 활용 시나리오의 현장 적용 문제점 및 기능의 오류 없이 정상적으로 작동함을 확인하였다. 이를 통해 본 연구에서 개발한 프로그램의 현장 활용성을 확인할 수 있었으며, 현장에서 측량 성과의 품질 확인 및 지하공간통합지도의 갱신 자동화에 기여할 수 있을 것이다. 또한, 국토교통부에서 추진하는 지하시설물도 정확도 향상 확산사업에 시범 적용하여 개발 프로그램의 활용성을 더욱 높일 것으로 기대된다.

This study proposes the direction of planning and designing for the media related facilities through the future concepts of media-center even though the concept and environment of the media-center are developed mealy at elementary schools in Korea. This study investigates and analyzes whether the present facilities are ready for the efficient education and improved facilities through comparison between after and before the 7th education program of systems of the academic support facilities. Therefore this study proposes the direction of developing and designing media-center through the field survey, make-up questionaries and analyzing architectural drawings of media related facilities for the future.

The purpose of this study to suggest the design guide line for the community center through the analysis of the satisfaction of the community facility and program in apartment. This study was approached by using both thoretical investigation and questionnaire survey. Survey was done examining 5 different apartment in Gwang-ju, which were all built from the year 2005 to 2007 and 268 residents were collected for questionnaire survey. As the result of this study, the satisfaction and usage of community facilities and programs showed higher indoor exercise field including yoga, golf and health club than others. Also the result can be used a basic data when planning new community center.

An ice storage cooling facility with cooling capacity of 150㎾ has been constructed for the purpose of developing optimal design and control strategy for an ice storage system. As the first step to this purpose, a computer program has been developed to simulate the operation of the ice storage system and examined precisely by comparing the results with those measured from the test facility. With the simulation program verified from the comparison, a design procedure has been developed to determine the minimum capacity required for each operation strategy available commercially. It is shown that the minimum sizes of the chiller and the storage tank are strongly dependent on the control strategy, i.e., chiller priority or storage priority, but less affected by the arrangement method, i.e., chiller upstream or chiller downstream.

The National Park should be preserved as described in the regulation. However, the development has resulted in degrading the environment in the park. Especially, the collective facility area has been developed for the commercial benefit rather than for the preservation. So, it is necessary to figure out the impact of the development plan proposed. Thus, the purpose of this study is to explore the hydrologic effects due to the collective facility area development in the National Park. The study site is the second collective facility area of Mt. Kyeryong National Park. The analysis of hydrologic effects due to the development has been carried out using the GIS in this study. The Rational Method and Soil Conservation Service(SCS) were used to estimate the runoff volume. During this procedure, GIS software, ARC/INFO was used to integrate, manipulate, and calculate the attribute value of a number of ploygons which represen each land use characteristic. A program was written to compute the attribute value of each polygon and to estimate the difference of peaktime runoff volume before and after development.

The HANARO, a multi-purpose research reactor of 30 MWth open-tank-in-pool type, has been under normal operation since its initial criticality In February, 1995. Many experiments should be safely performed to activate the utilization of the HANARO. A flow simulation facility is being developed for the endurance test of reactivity control units for extended life times and the verification of structural integrity of those experimental facilities prior to loading in the HANARO. This test facility is composed of three major parts; a half-core structure assembly, flow circulation system and support system. The flow circulation system is composed of a circulation pump, a core flow pipe, a core bypass flow pipe and instruments. The system is to be filled with de-mineralized water and the flow should be met the design flow to simulate similar flow characteristics in the core channel of the half-core test facility to the HANARO. This paper, therefore, describes an analytical analysis to study the flow behavior of the system. The computational flow analysis has been performed for the verification of system pressure variation through the three-dimensional analysis program with standard k-$\epsilon$ turbulence model and for the verification of the structural piping integrity through the finite element method. The results of the analysis are satisfied the design requirements and structural piping integrity of flow circulation system.

To validate the previous conceptual design of cover system, construction of the engineered barrier test facility is completed and the performance tests of the disposal cover system are conducted. The disposal test facility is composed of the multi-purpose working space, the six test cells and the disposal information space for the PR center. The dedicated detection system measures the water content, the temperature, the matric potential of each cover layer and the accumulated water volume of lateral drainage. Short-term experiments on the disposal cover layer using the artificial rainfall system are implemented. The sand drainage layer shows the satisfactory performance as intended in the design stage. The artificial rainfall does not affect the temperature of cover layers. It is investigated that high water infiltration of the artificial rainfall changes the matric potential in each cover layer. This facility is expected to increase the public information about the national radioactive waste disposal program and the effort for the safety of the planned disposal facility.

Simulation was conducted using TRNSYS to evaluate the thermal performance of a facility. This facility has a condensing-type heat exchanger which is able to recover the latent energy for the purpose of reducing the heating energy in winter. The boiler and chiller are selected based on the annual peak loads and controlled to maintain the facility at the set temperature of 14~$17^\circ{C}$. Supplied energy by the boiler and recovered energy by the heat exchanger were calculated as a function of number of pass through heat exchanger, kind of fuel and hot water velocity. Simulation results show that about 20% of the total heating load can be recovered by the heat exchanger and the amount of latent heat is increasing with the number of pass. This means that the efficiency of the waste energy recovery system can be increased by using a condensing-type heat exchanger rather than a traditional sensible heat exchanger.
