The purpose of this study was to propose an ecological management plan by the comprehensive analysis of biotope structures on Namsan Urban Natural Park in Seoul. Classified by actual vegetation, structure of layer and vegetation damage, biotope structures were composed of forest area, compact management area, herb area, cultivated area and non-ecology(urban) area. Succession had seened to stop in the Native forest. Artifical forest was divided into two types. The first, upper layer, was too dense to accommodate lower layer plants, the other case was the appearance of Quercus spp. and the first stage plants of succession following the declination of the upper layer plants. The soil pH of Nam-san Urban Park was 4.21∼4.51, which meant the soil was becoming acid. As the result of acidity, leaching of available nutrition(K/sup +/, NH₄/sup +/, Ca/sup ++/ etc.) was immediately influenced by the natural ecosystem, influence of acid rain was disturbed to becoming organic matter which was use to plants. In the case of a biotope structure management plan, the urban area was prohibited to spread outside. Cultivated and herb area was regenerated to natural forest. In the forest area, the compact management area was maintained with its present condition, and then it is desirable to make a preservation area and to plant shrubs. Planted Pinus densiflora Community was needed to eliminate competitive species of canopy layer, and plant shrubs. Management of deciduous broad-leaved Comm. was maintained in its present conditionand it is desirable to raise the diversity of the understory and shrub layer. The management of the artifical forest seems to be suitable for Q. spp. community. The care of naturalized plants prevents the expansion and restores the structure of wild plants. The soil management was a marked restoration soil ecosystem in order to prevent soil acid and drying.

Recently, landscaping construction has played a significant role in enhancing the quality of life for citizens by creating and maintaining outdoor spaces. However, landscaping projects vary in material procurement depending on the contracting method, and they also present various challenges in defect occurrence and defect rectification due to their specialized nature. In this study, we classified different types of projects based on material procurement ratios and conducted on-site assessments of defect status by specific processes. We also analyzed the itemization of material ratios and defect rectification costs. The results revealed it was found that projects with a higher proportion of government-provided materials had the poorest defect status in terms of planting works and also incurred the highest defect rectification costs. Moreover, conflicts concerning the responsibility for defects arose. Currently, there are no specific guidelines for setting standards for the proportion of government-provided materials in landscaping construction contracts. Furthermore, there is ambiguity in the management of defect rectification. Therefore, it is necessary to establish a systematic landscaping construction contracting framework by providing institutional guidelines tailored to local governments or the circumstances of contracting entities and to conduct thorough reviews of construction processes.

As the development of construction technology and new materials, building requirements has been varied gadually. Comfortable environment and serviceability of production activity and energy conservation are being dealt with very seriously. Recently localization of engineering technology of Power Plant, however, construction materials and domestic technology are being developed forcingly. According to above topics this thes is going to study roof waterproofing, thermal insulation and evaluate adiabatic performance and evaluation of properties of waterproofing materials and energy conservation. The results of studying and evaluating of roof waterproofing, thermal insulation and adiabatic performance of Power Plant are as follows. 1. Sheet waterproofing method is better than that of asphalt waterproofing method in that adaptability of wearhertight, thermal resistant, contraction and expansion. 2. It is required to replace polyurethane or ethylene used as thermal insulation with rock wool which is noncombustible materials. 3. It is recommended to usd outer insulation method than inner insulation method due to superioty of outer insulation method. Efficiency of insulation materials used in power plant is generally good except perlite mortar used in the power plant(YGN 1-2, GRI 1-2).

In steel making plant, sampling system for raw material such as iron ore, limestone is necessary for quality control purpose. For the sake of efficiency and productivity, automation of the sampling system is highly desirable. From technical standpoint, the development of the automated system requires multi-disciplinary domain knowledge such as mechanical engineering, industrial engineering, information technology and computer engineering. Up to present time, the development has been mainly carried out by a single domain expert with project manager. The automated system developed in this way caused problems in the final system. This paper suggests a systems engineering approach to the development of automation for raw material sampling plant via a tailored process called Plant Systems Engineering (PSE) Process based on ISO/IEC 15288. Through the PSE process, we could derive right requirements and architecture of the Systems Of Interest (SOI), and we were convinced that the PSE Process can be applied to many other Plant Systems.

This study is to establish the Incheon Metropolitan City Arboretum Development Plan (IMADP) as a capacity building both for plant diversity conservation and nature friendly leisure activity areas of Incheon Metropolitan City, Korea. The arboretum planning area is located within territory of the Incheon Grand Park Based on the IMADP, the arboretum was divided into three display spaces; the Urban Greening Garden, the Rare and Endangered Plant Species Garden and the Theme Garden. Detailed planting guidelines were suggested according to the three garden areas. The Urban Greening Garden was designed to display the following three; the relevance techniques, the model, and the practical uses of plants that are regarded to an urban greening. The Rare and Endangered Plant Species Garden (REPSG) was planned for the collection and display of the rare and endangered native plants in the territories of Incheon and the island seashore. Also, the REPSG includes the education purposes of comparing and displaying taxonomically related plant species. The Theme Garden was projected for the collection and display of plant species that have long been familiar to Korean culture and which are also used in our daily life.

This study was conducted to investigate the actual vegetation and plant community structure of the urban forest in Kwangju Metropolitan City. Thirty eight plots in the urban forest were set up by the clumped sampling method. The degree of green naturality, 6 that is artifical planting area covered 10.9% in Kwangju Metropolitan City and Pinus densiflora community covered 48.7% of the actual vegetations of urban forest. Canopy height, Diameter of breast height (DBH) and No. of species in urban forest were 13.5m, 21cm and 24 species, respectively. The soil conditions and community structure of the urban forest were differenced by location of urban and suburban area. The plant communities divided into six groups which were Quercus acutissima community, Q. acutissima-Robinia pseudo-acacia community, Pinus rigida Community, P. rigida-P. densiflora community, P. densifrora-Q. acutissima community and Q, serrata-P. densiflora community. Successional series of the urban forest in the surveyed area were proceeding from P. dinsiflora to Quercus species. The species diversity of plant were high in natural plant community but low in artificial plant community. Tree density in the canopy layer varied from 600ea/ha to 2,800ea/ha.

본 연구는 조경공사 표준품셈의 개정 작업이 진행되고 있는 현시점에서 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용의 특성을 비교하여, 향후 한국의 조경공사 표준품셈의 발전에 기여하는데 연구의 초점을 두고 진행하였다. 표준품셈과 표준보괘의 특성을 파악하기 위해서 한국의 경우는 2010년 '국토해양부'에서 제정한 건설공사 표준품셈 공종내의 조경공사를 연구 대상으로 하였다. 또한 일본의 경우도 2010년 '국토교통성' 제정 토목공사 표준보괘의 공원식재공사 표준보괘를 연구대상으로 하였다. 그리고 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘 공종 중에서 식재 공종에 초점을 두고 품셈의 범위, 세부 공종, 품셈의 구성, 수목 적용 규격, 품셈의 내용 등의 비교를 연구의 내용적 범위로 한정하였다. 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용을 비교하여본 결과, 한국의 조경공사 표준품셈은 독립적인 품셈과 품셈의 적용에 있어 융통성이 필요하다. 그리고 지주목에 대한 독립적인 품셈과 운반에 관한 품셈 규정 그리고 조경토와 관련된 품셈 등의 검토를 통하여 한국의 조경공사 표준품셈이 더욱 발전할 수 있다고 판단된다.
