  • Hundreds of contaminated sites have been generated due to the past mismagement of toxic substances, the lack of adequate environmental controls and ignorance of the potential environmental impacts of general activities in Canada. The general public, industry and governments have been addressing the contaminated sites with a number of cleanup responses. Environmental protection and remediation have become top priorities for the public and private sectors alike in Canada. Between the late 1980s and the early 1990s, the Canadian Environmental Protection Act and Canada's Green Plan were followed by provincial and territorial laws and policies to regulate contaminated sites. The National Contaminated Site Remediation Program(NCSRP) was initiated in 1989. It has been administered through bilateral agreements between the federal and participating provincial/territorial governments. They have committed a total of $250 million toward orphan site cleanup and technology development/demonstration over a five year period. The federal government has committed an additional $25 million to assess contaminated sites on federal crown land. Over 40 orphan high-risk contaminated sites, over 230 federal sites and over 35 technology development/demonstration projects have been addressed. The Canadian Council of Ministers of the Environment has developed a series of guidance documents to ensure a consistent and successful implementation of the Program. The management/regulation scheme of contaminated sites generally consists of: 1) identifying and investigating sites, 2) determining site contamination, 3) recognizing responsibility and liability, 4) assessing priority for remediation, 5) activation, evaluation and implementing remediation options, and 6) documenting remediation completion. The NCSRP supported the successful development/demonstration of a wide range of innovative remedial technologies. They are related to stabilization/solidification, thermal washing/flushing, advanced oxidation, sonics, and groundwater contaminated with hydrocarbons, PAHS, PCBs, heavy metals, and other hazardous pollutants in a variety of site environments.

  • The maintenance project of the Jeonglimsa temple site started with the objective of restoring the original structure of the temple, however, it was gradually transitioned to a landscaping maintenance project over time that constructs a landscape of the temple area. With paying attention to these facts, this study summarized the characteristics of cultural heritage landscaping of the Jeonglimsa temple site as follows. First, Cultural heritage landscaping is a landscaping act that creates, maintains, and manages landscapes within the spatial scope of the cultural heritage designated under the Cultural Heritage Protection Act and the cultural heritage protection area established around it. It is a work that includes protection and maintenance of the excavated remains, spaces by each function and plans for moving lines, Installation of structures to protect cultural properties, adoption of the facilities and structures for convenience of visitors, and construction of vegetation landscape. Second, the cultural heritage landscaping of the Jeonglimsa temple site has been developed in 5 periods, and these include 'the period of historical site investigation' that the temple name was identified through the designation of cultural assets and excavation investigation by the Japanese rule, 'the construction period of Baekje Tower Park' after the liberation from the Japanese rule, 'the period of Baekje Cultural Area Development Project' designated as a historical site, 'the period of the Comprehensive Development Project for a Specific Area of Baekje Culture',which was proceeded with the establishment of the park and museum instead of restoring the temple building due to the difficulty in gathering the pieces of historical evidence, and 'the period of the Jeonglimsa temple site restoring project', which was designated as a World Heritage Site while restoring the buildings deployment in the Buddhist temple at the time of foundation era of Baekje Dynasty. Third, this study verified the landscape changes of the Jeonglimsa temple site that have been transitioned, for instance, the creation of a commemorative park linked to the outer garden of Buyeo Shrine, the implementation of urban planning of the Japanese colonial era, the creation of a protective environment for the excavated historical structures and temple area, the restoration of building deployment in the Buddhist temple, and the sincerity restoration and utilization of cultural assets. Fourth, the landscape of Jeongnimsa temple site is determined by the subject and scope of cultural property designation, land use, movement lines and pavement, repairing methods of remains, structures, facilities, and vegetation. The characteristics of the cultural heritage landscape of Jeongnimsa Temple were derived, such as creating a procedural landscape considering the expansion of the cultural heritage designation scope, securing authenticity by maintaining relics in consideration of reversibility, creating a vegetative landscape suitable for historical and cultural landscapes, and enhancing the value of cultural heritage enjoyment by providing an open space.

  • IEC Standards on lightning protection system specify the use of natural components as down conductors. This paper provides an analysis of problems revealed from our field investigation and survey conducted for the relevant experts in the construction site where natural components are used as down conductors. It also considers a suitable condition for installing natural components as down conductors in accordance with the latest version of the standard. As a result, when rebars of reinforced concrete are used as down conductors, vertical bars consisting of rebars of which thickness is not less than D13($127mm^2$) should be connected by welding, clamps or bound joints, using appropriate connection components conforming to IEC Standards. The lashed joints, however, shall not be applied for down conductors.

  • The purpose of this study was to analyze their status of underground storage tank(UST) facilities and level of soil contamination, and to establish its management criteria. DB program was developed to analyze the correlation between specific characteristic of UST and level of soil contamination. For a suitable management of UST, leakage monitoring and inspection method of UST was investigated. Inspection period was established based on the leakage rate. The most dominant factor for leakage seemed to be caused by the corrosion. Therefore, main factor, construction method and installation year of UST, and corrosion protection system were suggested for optimal protection of UST. Considering the present management status of UST in Korea, inspection and management criteria of UST should be accomplished in term of contamination protection of leakage, and flexible regulation act should be introduced for each specific site.
