Domestic infrastructure facilities were built intensively in the 1970s and 1990s, and the resources required for maintenance and repair will increase sharply within the next 20 years. ‘A Comparative Study on the Classification and Financial Size of SOC(2012)’ showed that the size of the domestic infrastructure facility is shrinking. In this study, we investigated the case of asset management research and analyzed the trend of the aging of the domestic infrastructure. And then we present the direction of future research.

Four requirements for the operating and supporting system for sustainable landscape management will be discussed through this paper. The requirements are based on multiple case studies on the structure and the process of development of three organizations that have been contributing to the sustainable rural landscape management in Japan since 1989. The first requirement is that the residents should recognize regional problems and voluntarily organize a group which can properly deal with the problems. Secondly, members of the organization should have a solid grasp of the goal of their activities (or founding principal of the organization) and share it among themselves. Founding principal should include the history of natural circulation system in the area, cultural features and a future plan in association with human resources. Thirdly, the administration of the organization should be separated from the founder, the residents. The administration, such as business promotion, becomes more effective when consigned to a separate entity, not to the residents. Lastly, the interaction among separate entities is crucial to promote diverse activities for the local landscape management. The administrators and experts need to cooperate to draw a precise conclusion regarding the way of interaction. These requirements drawn from the Japanese case studies should be localized to the Korean circumstances for further adoption.

국가물류경제의 중축산업인 항만의 지속가능한 운영과 개발을 위해서는 인프라 확충을 통한 경쟁력확보와 더불어 대기오염, 수질 오염, 소음 및 생태계 파괴 등의 항만환경문제로 인한 지역커뮤니티와의 갈등해소가 더 중요한 요소로 부각되고 있다. 우리나라 부산 신항만 개발사업의 경우도 신항만 공사용 바다모래 채취로 인한 어민들과의 갈등 때문에 항만공사가 중단된 경험이 있으며, 그 주요 원인으로 현행 어업피해조사제도를 포함한 항만환경피해에 대한 정량적인 영향성 평가법의 부재와 한계라 할 수 있다. 따라서 본 연구의 주목적은 우리나라 항만의 지속가능한 항만운영 및 개발을 위한 효율적인 항만환경관리에 필수적인 정량적 환경영향성평가 방안의 제시에 있다. 이를 위해 국내 외 항만의 환경정책과 사례분석을 통해 전반적인 항만환경문제와 그 영향(피해)에 대해서 살펴보고, 피해를 입은 환경재와 서비스의 전체적 경제적 가치를 평가할 수 있는 경제적 가치평가법을 제시하였다. 제시된 방법론 중에서 부산 신항만 개발로 따른 정박지 지정으로 인한 해양 생태계 서비스 피해 사례에 대해 보다 과학적으로 추정할 수 있는 Habitat Equivalency Analysis(HEA)를 적용하여, 예시적인 피해액을 추정 하였다. 본 연구의 결과를 토대로, 제시된 항만환경피해에 대한 경제적 영향성평가방법론의 제도적 도입을 통하여 보다 효율적인 항만환경관 리방안을 제시하였다.

The existing domestic bridge has become deterioration with the increase of bridges to be managed. Therefore appropriate maintenance such as an inspection, diagnosis, repair, and rehabilitation is required to extend the service life of the bridge. The domestic and international cases of the maintenance budget for bridges were investigated and analyzed. As a result, surveyed countries represent maintenance cost as only accounting values without clear and accurate categorized maintenance items.

A lot of bridges have been built with economic growth and national development for a long time. The existing domestic bridge has been become deterioration with the increase of the quantity management. Therefore appropriate maintenance such as an inspection, diagnosis, repair, and rehabilitation is required to extend the service life of the bridge. The domestic and international cases of the maintenance for inspection personnel were investigated and analyzed. As a result, there was hardly clear and accurate criteria about inspection personnel but Denmark. However, the qualification and competence of the team members have been presented.

Defects of diversion tunnel have been analyzed by using the precise inspection for safety and diagnosis in 7 dams. Leakage from joint, crack, and material segregation is crucial damage in dam as well as crack, corrosion, and drainage system. Maintenances of diversion tunnel have been suggested with common and unique characteristics of defects.

The purpose of this study is on identifying charactreistics and management direction of complementary pond of Dalmaji village in Gangjin. Accordingly, this village was indicated as Experience and Resort village by Korean government. This study describes the construction background and characteristics and identifies species diversity and characteristics through field survey. For this, literature and field survey was performed. In field survey, vegetational survey was performed in Aug. of 2015. D(Dominant degree) and S(Sociability degree) was measured by Brown-Blanquet's method. The answer was searched from Myungsanron(明山論), a textbook of Fengsui(風水) in Joseon dynasty. Of these causes, it was considered that the representative one is a protection of fire and infectious disease because the Wolgak mountain is a fire mountain(火山) as a stone mountain in Fengsui. The results demonstrate decline of aquatic ecosystem because of neglect management. The total number of species was 24. Of the species, Zelkova serrata is a natural vegetation of this complementary forest. This is nominated as Lagerstroemia indica and Camellia japonica community. Species composition demonstrate the characteristics of Korean southern region as mixed forest of evergreen trees and deciduous ones which are indigenous plants. It was considered Juniperus chinensis KaizukaVariega in central round island was planted in Japanese colonial period and it have to be removed. It was considered that name of moon pond and moon island etc. projects the mind of village ancestors which are going to reach an ideal condition of moon. And management of quantity and depth of pond water was critical for restoration of disappearing lotus from related literature. Periodic management was needed for ecological structure and function improvement because of ecological disturbance by the invasive plants like Humulus japonicus.

방사성폐기물의 처리와 관리는 원자력을 이용하는 국가들이 반드시 해결해야 하는 중요한 문제이다. 오늘날 동 사안에 대 해서는 극소수의 국가들만이 실질적인 진척이 있으며, 그 중 프랑스의 관련 정책이 대표적인 성공 사례로 평가되고 있다. 한국의 경우에 있어서도 방사성폐기물의 관리에 대한 적절한 정책의 준비가 필요하며, 이에 프랑스 법제화 접근법을 적용 하자는 제안들이 있다. 동 연구는 그 적용성 검토를 위해 방사성폐기물의 관리와 관련된 두 나라의 기술 현황 및 사회정책 적 지표를 비교하였으며, 자원 재활용과 사회적 수용성 증진 전략 측면에서 프랑스식 법제화 모델을 반영하는 것이 바람직 하다고 판단한다.

A historic urban landscape has to be preserved wholly, not only as a cultural heritage site, but also as an environment and a neighborhood. However, cultural heritage sites have their own unique social-commercial environments, and these are not easy to integrate during the preservation process even though they are located in the same area. To examine ways of overcoming the difficulty in integrating the preservation of heritages, this study analyzes the historic urban landscape preservation of St. Augustine, Florida in the United States. The preservation of St. Augustine's historic urban landscape can be identified by its unique system of government-academy cooperation. For integrated preservation of the historic landscape of St. Augustine, Florida's state government owns the properties, which are not designated but have a heritage value, and are located next to the nationally designated heritage sites. The properties receive trust administration by the University of Florida. This cooperation between the government and the university can benefit both stakeholders. To the government, the relationship gives the benefit for professional, long-term management for the properties and their environments. To the university, the cooperation provides a place for practical education, funding, and opportunities for research and management. The government-academy cooperation model argued for this study can be applied to many Korean historic cities' urban landscape preservation planning.

The suspension bridge main cable requires regular maintenance works to control the axial forces of the cable band bolts. A axial forces of a suspension bridge cable band occur reduction phenomenon because of the creep behavior of cable wire, the bolts relaxation, load fluctuation and cable rearrangements with the lapse of time.

Nowadays, wireless sensor network applications have been used in several important areas, such as healthcare, construction, critical infrastructure, environmental monitoring, and manufacturing. However, due to the limitation of WSNs in terms of memory, energy, computation, and scalability, efficient management of the large number of WSNs data in these areas is an important issue to deal with. There is a need for a high-performance computing and massive storage infrastructure for real-time processing and storing of the data as well as analysis of the information. In this paper, we present a technology and application of sensor cloud computing based on IoT and service to manage monitoring sensor data for the f construction design-build projects. With this IoT sensor cloud platform, the entire project participants can efficiently share information to identify and solve issues in the design build phase.
