The donation collection system to secure infrastructure and land necessary for public development projects has been actively applied as an effective means of realizing public interest and the concept of recovering development profits, and has contributed greatly to society in public difficult financial conditions. However, due to the ambiguous legal standards and lack of legal grounds for the operation of the donation collection system, it has been arbitrarily used for administrative convenience in the form of granting a donation collection assistant to install infrastructure. In addition, infrastructure is a facility that is constructed and donated within development profits to obtain licenses, and is promoted to minimize construction costs to improve profitability, posing a risk of poor infrastructure planning, design, and construction, resulting in increased safety and maintenance costs for citizens. Continuous system and legal improvement are needed to improve the excellence, convenience, and safety of facilities that citizens will use for half a century through the improvement of the donation system.

각 관공서나 공공기관에서 발생되는 각종 공사현황정보와 기술정보를 시설물 전체 수명주기동안 제대로 활용하기 위해서는 시설공사관리 업무를 전자처리체계로 전환하는 것이 시급하며, 사업계획에서 준공까지 일련의 과정에서 발생하는 문서들의 보관이 비체계적이므로 이를 잘 보관하고 재 사용하기 위한 관리체계가 필요하다. 따라서 본 연구는 공공건설분야를 담당하고 있는 지방국토관리청을 대상으로 사업단위별로 업무를 7가지로 세분화하고. 그 중에서도 핵심부분인 공공건설사업에 대한 체계적이고 효과적인 관리체계를 유지할 수 있는 웹 기반의 공사현황 정보시스템을 제안한다.

Riverfront facilities are river space facilities used by citizens for the rest and convenience. Recently, although the importance of efficient maintenance of riverfront facilities is increasing, damaging facilities cases are increasing due to frequent floods. Currently, the inspections and diagnosis of river space facilities are limited to the main flood control facilities. And the standards for the maintenance and management of the riverfront facilities are insufficient. Utilization survey, which is the standard for managing river space facilities, is also inefficient in terms of manpower consumption and economic feasibility. This study uses mobile big data to classify river usage and conducts a survey for usability of river facilities to derive economic evaluation for usage performance. In the future, if economical method system that considers safety, usability, and durability is conducted and demanding analysis for each convenience facility is evaluated, it is expected that the efficient maintenance of riverfront facilities is perfomed better and the use of rivers by citizens will further increase.

하천 혹은 그 인근에 설치된 시설물은 수문, 통문, 제방, 댐, 보, 배수펌프장, 상·하수도, 하구둑 등이 존재한다. 이러한 하천 시설물은 홍수나 가뭄 등 수해를 저감하는 역할을 한다. 그러나 많은 하천 시설물은 노후화, 기후변화, 하천환경변화 등으로 구조적 혹은 기능적 안정성의 저하가 우려되는 실정이다. 시설물 유형별 고령화율을 살펴보면, 댐, 하천, 상하수도 순으로 조사되었으며, 준공연수가 30년을 초과한 하천 시설물은 약 40%를 넘어섰다. 그럼에도 불구하고 하천시설물의 관리 구조는 시설물 설치단계까지만 치중되었으며, 이후 계획 재수립 단계까지의 평가 및 모니터링, 유지관리, 정보관리 등에 이르는 선순환 구조가 미흡한 실정이다. 시설물의 노후화에 따라 유지관리 비용이 증가하며, 대형사고로 이어질 수 있기 때문에 적절한 시기에 시설물 점검 및 유지보수가 매우 중요하다. 우리나라의 경우 시설물의 안전 및 유지관리에 관한 특별법에 따라 국가주요시설물은 안전점검을 실시하고 있으며, 시설물통합정보관리시스템(Facility Management System; FMS)에 안전등급을 제공하고 있다. 본 연구에서는 FMS의 하천 시설물 안전등급 현황을 기반으로 시설물의 효과적인 생애주기관리를 위해 하천 시설물의 성능평가모델을 제안하였다. 성능평가모델은 하천 시설물의 사용연수에 따른 안전등급의 예측이 가능하며, 관리자 측면에서 예산투입 등의 의사결정 시 활용이 가능할 것으로 판단된다.

지하매설물이란 땅속에 묻혀있는 상수, 하수, 전기, 통신, 전력 등 도시기반시설을 의미하며, 지상시설물에 비해 관리가 어렵고 예기치 않은 사고로 인해 많은 재산상, 인명상 피해를 입힐 가능성을 안고 있다. 우리는 서울 아현동과 대구에서의 대형 가스폭발사고, 도로굴착공사가 끝난지 얼마 안되는 지점에 또다른 매설물의 매설 또는 유지보수를 위해 중복공사가 일어나 교통에 혼잡을 유발하게 되는 경우를 빈번하게 경험하면서 도시의 동맥역할을 하는 이러한 지하매설물에 대한 체계적 관리가 시급함을 실감하게 된다. 특히 선진외국에서 GIS를 도입하여 지하매설물을 데이타베이스화하고 지하매설물 관리체계를 개발하여 지하매설물을 체계적으로 계획하고 관리하며, 대형사고를 사전에 예방하고, 사고가 일어난 경우에는 GIS를 활용하여 보다 신속하게 대처함으로서 피해를 최소화하는 실정을 감안할 때 GIS도입이 이러한 매설물에 대한 체계적 관리를 가능하게 하는 방안으로서 적극적으로 검토되어야 함을 느낀다. 본 글에서는 첫째, 이러한 지하매설물의 관리실태와 문제점을 분석하고 둘째, 현재 국가 및 서울시에서 추진 또는 계획 중인 지하매설물 관리체계 구축사업내용과 셋째, 지하매설물 데이터베이스가 어떻게 구축되고 유지.관리되어야 할 지에 대하여 간략히 살펴보고자 한다.

Built in urban ares tunnels is necessary to accurately grasp not only the above-ground environment of the tunnel but also the below-ground environment of the tunnel for design and construct. However, fully coupled analysis of stress and flow is very difficult due to the limited function of the tunnel numerical analysis program and difficulty in using program. This can lead to excessive design that increases the construction cost or occur problems that can lead to accidents during construction. In particular, in the case of an urban tunnel has a low layer soil section above the tunnel and the groundwater level exists in the upper layer of the tunnel. Therefore, a reduction in the groundwater level during underground construction may increase the effective stress of the upper layer and cause the ground to subsidence. So It is necessary to design after accurately evaluating the change in the groundwater level. In this study, the tunnel's behavioral characteristics were analyzed through fully coupled analysis of stress and flow according to the drainage type for an urban underground tunnel.

The hacking threats made against the Korea Hydro & Nuclear Power(KNDP) and the leakage of critical information on nuclear power safety raised the public awareness on the importance of protecting and managing national infrastructure necessary for sustaining the state and society. Cyber security activities and relevant institutions in the ROK, however, are still insufficient, because of which there is a possibility that similar incidents would reoccur and cause serious damages. Hence, a grave and direct threat is posed to the national security of the ROK. In this thesis, I would like to give my analysis and assessment on the recent cyber intrusions against infrastructure at home and abroad, measures established in response and their implementation, and the deficiency of the existing infrastructure protection system ; and lastly propose measures to reinforce infrastructure protection of the ROK.

Domestically, technical condition evaluation for breakwaters has been conducted through safety checks and safety diagnosis. If necessary, maintenance for the facility is conducted. However, in recent years, the need for infrastructure management has been increasing from a life-cycle-cost perspective. For these reasons, the "Sustainable Infrastructure Management Basic Act" was enacted. Previously, only the technical part of the breakwaters was evaluated. However, based on the act, comprehensive management of breakwaters will be possible through performance improvement by adding economic and political evaluations. In this study, evaluation factors and evaluation methods were developed for a breakwater rehabilitation project. The purpose of this study is to present a development direction, items, and methods for the evaluation of breakwater performance improvement to be applied in future practice. This study reviews the concept of maintenance and performance improvement, the literature related to performance improvement, and the project type for the common standard of performance improvement. Evaluation items and evaluation methods for breakwater rehabilitation are suggested to be reviewed by experts. The methodology suggested in this study could be used for preventive maintenance and to reduce accidents.

A number of BTL projects for educational facilities have been augmented because of the increase of newtown development and deflationary policy of class size for learning efficiency. As the operation and maintenance costs rapidly increase, the budget for operation and maintenance is expected to be short. Therefore the asset management maximizing asset value is required to clarify the budget plan and distribution and provide a qualitatively high service. The main objective of this research is to establish asset valuation process in educational facilities delivered by BTL project. In order to meet the research objective, the asset valuation process is established by literature reviews, expert advice, and lessons learned from the developed countries. The developed process includes depreciation by internal accounting law, the core element of valuation, and asset valuation process. The results of the research will be help to offer the qualitatively high service and explain the standard of budget plan. It will assist commencing the asset management system.
