Singapore, a city state with less than 6 million population, has continued successful cooperative development and become one of the most successful Asian countries in exporting expertise in urban and real estate development. This research aims to analyze Singapore's cooperative development with socialist countries including China and Vietnam from Singapore's perspective as an investor. For cooperative development projects in China, Singapore adopted Singapore-style physical urban planning concepts as well as its own institutional and administrative systems. Singapore-Vietnam cooperative development managed to acquire profitable land and diversify its portfolio in terms of industry types and rents. This made Singapore's industrial parks more competitive than other parks in Vietnam. By showcasing successful project implementation in China and Vietnam, Singapore has proved that its model for industrial park and urban development is transferable. Singapore's success in cooperative development with socialist countries provides important implications for future cooperative development between South and North Korea. For example, phased development approaches starting from individual industrial parks expanding to mixed-use townships will be very useful to realize sustainable urban planning in North Korea and reduce financial risks. Singapore dominated development opportunities in advance when socialist countries opened their economy. To pattern ourselves after Singapore, we should not only improve our relationship with North Korea but also prepare with practical components such as financing and organizational structure.

Landscape change is the modification and replacement of landscape elements in accordance with human management and natural disturbance on land mosaics. During landscape change, changes in patterns such as heterogeneity, diversity and shape, and juxtaposition of spatial elements are also accompanied. For the sustainable landscape system, therefore, spatial characteristics of the landscape should be considered in implementation of landscape conservation and restoration planning. Short-term changes of land-use and landscape pattern during the 10 years of 1980s and 1990s were investigated in the agriculture-forestry dominated landscape system through the statistics and the analysis of landscape-vegetation map. Study area is Yangdong-myon, Yangpyung-gun (37°27′30"N, 127°46′50"E), Kyonggi-do, in central Korea. Landscape change of this region was significantly related to the recent industrialization according to socio-economic development. Analyses of landscape pattern show that the area of secondary forest sustained by human activity decreased and it was replaced with large exotic plantations during this period. Area of paddy field was also extended. Fractal dimension of the total landscape increased, but that of paddy field area decreased due to rearrangement for mechanized farming. Moreover, the area of landscape management regimes such as plantation and cultivation increased in land mosaics during this period.

The purpose of this study is to evaluate naturalness of botanical garden pre- and post-assessed according to the Hemeroby Index in the case study of Daegok Botanical Garden. The results of the study are as follows. 1) The results of the site analysis according to the Hemeroby Index before development have been appeared that highest of poly/meta-hemeroby is 45.8% and the next of meso-hemeroby is 28.3%. 2) After development, the highest of meso-hemeroby is 53.6% and the next of $\alpha$ -euhemeroby is 28.3%. Generally, it is considered that the naturalness according to Hemeroby Indx was lasted higher after development than that before development. 3) Both a-hemeroby and oligo-hemeroby are not appeared before and after development. $\alpha$ -euhemeroby and meta-hemeroby are not appeared before development, but htey increased as much as 16.8% and 6.8% after development. Most of all, the increase of meta-hemeroby after development results from the increase of the artificial facilities (e.g. pavements, buildings and so on). 4) Specially, through the modification of play ground, park lot, pavement classified to meta-hemeroby, it is considered that the Hemeroby Index would be improved. 5) Compared with existing naturalness grade of green space, it has merits to apply Hemeroby Index, especially as a menas of distinguised naturalness assessment in various land use pattern. But there is no clear evidence that limits the minimum size that could be applied with Hemeroby Index. So, we must discuss whether it was useful to apply this standard to such a small specific space as the site of this study.

The present study investigated the causes and intensity of the urban heat island phenomenon by the seasons according to the pattern of land use in Chungju City. Highest temperature and lowest moisture areas of the urban were very similar to the distribution of commercial districts, on the other hand, lowest temperature and highest moisture areas were distributed in manufacturing districts, green zones and the Hoam Lake. If appear at intensity of the distance from the outer circumference of commercial districts, wind direction and the rise of temperature, we could observe the remarkable expansion of high temperature from commercial districts toward residential districts around of downwind in all seasons. In case the effect of the wind was not significant as well, high temperature in commercial districts appeared tendency that a little spread to 1, 2 residential districts around. But checked up the intimate relations between the amount of moving heat and wind, when out of consideration that size of area was not much compared than residential areas of downwind affected by the wind. These phenomenon was relatively obvious in summer, the other side, in spring and autumn appeared a similar tendency.

Twenty-four wetlands located in Higashi-Hiroshima City in West Japan were selected for this study in order to investigate both the relationship between aquatic plant composition and environmental conditions; and the relationship between changing land use patterns in the catchments and the concentration of different forms of nitrogen in the wetlands. The dominant and subdominant species which comprised the principal vegetation were determined based on a vegetation census conducted in each wetland during the growing season from June to August, 2006. The seasonal variations of water quality factors (pH, electrical conductivity, turbidity, dissolved oxygen, total dissolved solid, and temperature) and different forms of nitrogen such as nitrite, nitrate, ammonium, total nitrogen, dissolved organic nitrogen and dissolved inorganic nitrogen concentrations were analyzed as important indicators of water quality for the surface water of the wetlands. The surveyed wetlands were classified into three types (non-disturbed wetlands, moderately-disturbed wetlands and highly-disturbed wetlands), based on the degree of human disturbance to their catchment areas. An analysis of variance indicated that there was a significant difference among the wetland groups in the annual mean values of electrical conductivity, total dissolved solids, total nitrogen, nitrite, dissolved inorganic nitrogen and dissolved organic nitrogen. Classification of the wetlands into three groups has revealed a pattern of changes in the composition of plant species in the wetlands and a pattern of changes in nitrogen concentrations. A majority of the non-disturbed wetlands were characterized by Brasenia schrebi and Trapa bispinosa as dominant; with Potamogeton fryeri and Iris pesudacorus as sub-dominant species. For most of the moderately-disturbed wetlands, Brasenia schrebi were shown to be a dominant species; Elocheriss kuriguwai and Phragmites australis were observed as sub-dominant species. For a majority of the highly-disturbed wetlands, Typha latifolia and T. angustifolia were observed as dominant species, and Nymphea tetragona as the sub-dominant species in the study area. An analysis of land use and water quality factors indicated that forest area played a considerable role in reducing the concentration of nutrients, and can act as a sink for surface/subsurface nutrient inputs flowing into wetland water, anchor the soil, and lower erosion rates into wetlands.

It is necessary to predict future water pollution sources in the establishment of Total Maximum Daily Load (TMDL) plan for watershed management. There are some difficulties and limits in estimating the pollution sources accurately since the prediction method is not firmly established. This study reviewed the existing methods of prediction and developed a technique characteristics. The characteristics were obtained by analyzing the change pattern of pollution sources by region and incorporated in the technique. A distinctive feature of the technique is to eliminate the influences of land use change included in the pollution source data of a region. The technique has been applied and tested. The test result showed the improvement on the prediction accuracy. A computer program was also developed for the easy application of the technique.

The landscape systems in Korean island settlements can be recognized as results of ingabitants' ecological adptation to the isolated environment with the limited natural resources. Both the fishery dominant industry in island society and ecological nature of its environments seem to have influenced on inhabitants' environmental cognition as well as the physical landscape of island villages such as its location, spatial pattern in each village, housing form and so on. This study was done mainly by both refering to the related documents and direct observations in case study areas, and results of the study can be summarized as follows. 1. In general, the landscape of an individual island seems to take more innate characteristics of island's own, corresponding to the degree of isolation from mainland. That is, while the landscape of island in neighboring waters takes both inland-like and island-innate landscape character at the same time, the one in the open sea far from land takes more innate landscape character of all island's own in the aspects of village location, land use and housing density etc. 2. The convex landform of most islands brings about more centrifugal village allocation than centripetal allocation in most inland villages. And thus most villages in each island face extremely diverse directions different from the south facing preference in most inland rural villages. 3. Most island villages tend to be located along the ecologically transitional strip between land and sea, so called 'line of life', rather than between hilly slope and flat land as being in most inland village locations. So they are located with marine ecology bounded fishing ground ahead and land ecology bounded agricultural site at the back of them. 4. The settlement pattern of the island fishing villages shows more compact spatial structure than that of inland agricultural villages, due to the absolute limits of usable land resources and the adaptation to the marine environment with severe sea winds and waves or for the easy accessability to the fishing grounds. And also the managerial patterns of public owned sea weed catching ground, which take each family as the unit of usership rather than an individual, seem to make the villagescape more compact and the size of Individual residence smaller than that of inland agricultural village. 5. The folk shrine('Dand') systems, in persrective of villagescape, represent innate environmental cognition of island inhabitants above all other cultural landscape elements in the island. Usually the kinds and the meanings of island's communal shrine and its allocative patternsin island villagescape are composed of set with binary opposition, for example 'Upper shrine(representing 'earth', 'mountain' or 'fire')' and 'Lower Shrine(representing 'sea', 'dragon' or 'water') are those. They are usually located at contrary positions in villagescape each other. That is, they are located at 'the virtical center or visual terminus(Upper shrine at hillside behind the village)' and 'the border or entrance(Lower Shrine at seashore in front of the village)'. Each of these shirines' divinity coincides with each subsystem of island's natural eco-system(earth sphere vs marine sphere) and they also contribute to ecological conservation, bonded with the 'Sacred Forest(usually with another function of windbreak)' or 'Sacred Natural Fountain' nearby them, which are representatives of island's natural resources.

본 연구는 성장과정에서 나타나고 있는 공간적 확산 집중의 특성과 도시공간구조 변화를 측정하는데 목적을 두고 있다. 분석에 사용된 자료는 도시인구, 고용, 개발연면적, 지가를 이용하였다. 분석시기는 1995년이후 10년간으로 1995년, 2000년, 2005년을 기준으로 하였다. 연구방법은 먼저 도시성장 변화를 측정하기 위하여 중심점 이동과 표준편차거리를 산출하였다. 모란지수(Moran's I)분석결과 분산된 형태보다는 전반적으로 집중된 형태를 보이고 있었으나, 그 수준은 다소 미약하게 나타났다. 앞으로 시가화지역에서는 토지이용 등의 계획적인 도시관리가 요구된다고 볼 수 있다. 다음으로 윤곽도로 볼 때, 대체적으로 단핵구조에서 다핵화로 변화된 모습을 보이고 있다. 다만 중심지간에 상호연계축 발달은 미약하였다.

최근 새로운 도시개발의 패러다임으로 지속가능 한 개발에 대한 관심이 고조되고 있다. 지속가능 한 도시개발을 위해 통행량과 통행거리를 줄이는 교통정책과 혼합 고밀의 토지이용을 유도할 수 있는 정책을 수립해야 한다는 점에 대해서는 공감대가 형성되어 있다. 그러나 실증적 차원에서 과연 어떤 정책들이 에너지 소비와 대기가스 방출량을 저감시킴으로서 지속가능 한 도시개발을 도모하는데 효과적인가에 대한 경험적 연구는 매우 부족한 편이다. 본 연구는 지속가능 한 도시개발을 위해 수립한 정책들의 효과나 영향력을 평가할 수 있는 계획지원시스템의 구축과 활용성을 모색하는데 목적을 두었다. 이를 위해 정책대안에 따른 시나리오를 구축하고 이를 시뮬레이션 하여 그 결과를 비교 평가하는 전 과정을 처리할 수 있는 시스템을 개념적으로 설계하였다. 이 시스템은 크게 투입-모델링-산출의 세 구성요소로 되어 있으며, 가장 핵심적 요소는 토지이용과 교통체계, 환경모델을 통합화하는 모델링이다. 토지이용-교통-환경모델을 통합화하는 접근방법에 대한 장점은 잘 알려져 있으나, 실제로 통합모델을 운용할 수 있도록 개발된 소프트웨어는 매우 적다. 본 연구에서는 지속가능 한 도시개발을 위해 토지이용-교통 통합모델로 알려진 TRANUS의 활용 가능성을 검토하였다. 용인시를 사례로 하여 초기화시점에서 TRANUS를 작동시킨 결과 토지소비량, 총 통행량과 통행거리 및 비용, 에너지 소비량, 대중교통수단 분담율 등 지속가능성 수준을 측정, 평가할 수 있는 결과물들이 산출되었다. 따라서 TRANUS는 우리나라에서도 지속가능 한 도시개발을 위해 효과적인 정책대안을 선정하는데 활용 가능성이 높은 시스템이라고 볼 수 있다.
