U-City 기반시설의 구성요소는 지능화된 시설, 정보통신망, 통합운영센터로 구분되며, 기존 연구에서의 U-City기반시설은 효율적인 운영 관리의 필요성을 제시하고 있다. 그러나 그 중 법에서 정의하는 내용과 다르게 해석하는 경우가 지능화된 시설에서 빈번히 발생하고 있다. 이러한 문제의식을 토대로 국내 지능화시설 관련 법제도 및 운영관리의 문제점 등을 종합적으로 분석하여 지능화시설의 효율적 활용을 위한 통합운영방안을 마련하고자 한다. 이를 위해 관련 법제도와 실무담당자 인터뷰를 통해 지능화시설의 현황 및 문제점을 파악하고, 지능화 시설에서 생성된 도시정보 및 설치위치를 모두 포함한 통합 활용의 필요성을 도출하였다. 현재 정부부처 및 지자체는 ICT를 활용한 다양한 정보시스템을 구축 운영하고 U-City법에서는 통합적 관리 운영을 명시하고 있으나, 시설 운영주체에 대한 구체적인 책임과 권한에 관한 정의는 명확히 이루어지지 않고 있다. 이를 효율적으로 운영하기 위해 설치된 장비와 여기서 생성된 도시정보를 공동으로 활용할 수 있는 관련 부서 간 원활한 조정이 가능한 추진체계가 필요하다. 본 연구는 지능화시설의 관련법 및 법규들에 대한 논리적 연계의 관계를 정립하여 효율적인 지능화시설 설치 및 관리를 위해 일원화된 법적 시스템의 체계를 마련하고자 한다. 이를 통해 지능화시설의 통합연계 및 활용을 위한 관리체계의 기초 토대가 될 수 있을 것으로 기대한다.

For economic evaluation of integrated operation to sewage facilities, benefit-cost analysis was performed to watershed sewage works project in 7 watershed areas, 156 facilities. In this study, the cost before and after integrated operation was compared and benefits are calculated from the reduction of operators, increasement treated pollution loads, reduction cost through operation convenience, reduction water consumption through effluent reuse, and improvement of life benefit. The result showed that cost was 8,500million won and benefit was 16,747million won, so benefit was 49% higher than cost. B/C analysis result showed that B/C ratio was 1.97 and it is similar to other researches. The benefits of integrated operation included convenience of data management, increase of emergency response, decrease of complains with sewage which was not reflected numerically, so the benefits of integrated operation were expected much greater than this result

Web based integrated sewer management system was developed for the analysis of sewer flow and for the optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly information management system. The developed system was applied to the residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of the developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of stormwater, surface and subsurface environment in order to develop an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer network and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for the optimal management, but also for the decision support system to examine the efficiency of planning and implementation of sewer projects.

The monitoring system for integrated management of on-site wastewater treatment plants(biofilter) was designed and its operation program was developed. In design process, the research on monitoring parameters which will be able to represent condition and operation of the pilot plants was accomplished, and these parameters came to reveal with ORP(Oxidation-Reduction Potential), water level, pump and power on/off. Proposed monitoring system is composed with measurement, control, communication and display device, and PCB(Prototype Circuit Boards) and microcontroller (PIC16F877) technique are applied to its design of control device for performing specific function. also, The operation program of PC setup is developed in order to provide a convenience to the manager.

Number of researches on efficient terminal operation system applying RFID(Radio Frequency Identification) are in progress. However, RFID has limitations on tracking and providing accurate positions of containers. In this paper, to enhance the performance of the integrated terminal operation system, an efficient loading management of yard is proposed by applying RFID based RTLS(Real Time Locating System) that provides real time accurate positions of containers. It was found that a group based sequence system is more efficient than the existing individual sequence number system in the container yard In the group based sequence system, the containers in the same group should have similar characteristics such as port of destination(POD), size, weight, etc. In order to run this system, we proposed the parameters to the unspecified N bytes of RFID tag which are specified in ISO 18000 7. And then, we developed an integrated operation system of container terminal using RFID. The proposed system reduces the ship turnaround time in ubiquitous port environments.

According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railway Safety Audit (IRSA) and has implemented the safety audit to the Railway operation agencies such as Korea Railway (KORAIL) and the Railway facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the Railway operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.
