  • The main aim of this research is centered on the relation between nature and humans, and is to study the ecological characteristics appearing both in Landscape Architecture, one of the currents of ecological architecture as the architectural solution on the relation between humans and nature, and in our traditional architecture. Through this study, we were able to see that our traditional architecture was influenced by our ancestor's view of nature, and that the foremost feature of our ancestor's view of nature on our traditional architecture is not conflicting with nature, but, instead it is complying with it through seeking harmony with nature. Also we could see that our ancestor's view of nature is similar to Landscape Architecture having come to the fore toward the tendency of modern ecological paradigm in that it is the representation seeking the organic view of nature pursuing the oneness among artificial structure, humans, and nature. That is, we could figure out that various ecological features appearing in modem Landscape Architecture had been represented for a long long time, in a natural fashion, In the manner of space makeup in our traditional architecture. This is the characteristic of our ecological thinking system understanding nature and humans at the same context, and it has come down not only to our everyday living but to the manner of architectural solutions as well. Through this research, we could reconsider the modern value of ecological architecture inherent in our traditional architecture.

  • The objectives of study were to evaluate fish species compositions of trophic guilds and tolerance guilds and apply ecological fish assessment (EFA) models to Bekjae Weir, Keum-River Watershed. The EFA models were Stream Index of Biological Integrity (SIBI) used frequently for running water and Lentic Ecosystem Health Assessment (LEHA) used for assessments of stagnant water. The region of Bekjae Weir as a "four major river project" was originally a lotic ecosystem before the weir construction (2010, $B_{WC}$) but became more like lentic-lotic hybrid system after the construction (2011, $A_{WC}$). In the analysis of species composition and ecological bioindicator (fish), fish species with a preference of running water showed significant decreases (p < 0.05), whereas the species with a preference of stagnant water showed significant increases (p < 0.05). After the weir construction, relative abundances of tolerant species increased, and the proportion of insectivores decreased. This phenomenon indicated the changes of biotic compositions in the system by the weir construction. Applications of SIBI and LEHA models to the system showed that the two model values decreased at the same time after the weir construction ($A_{WC}$), and the region became more like lentic-lotic hybrid system, indicating the degradation of ecosystem health. The model values of SIBI were 19 and 16, respectively, in the BWC and AWC, and the health conditions were both "C-rank". In the mean time, the LEHA model analysis showed that the values was 28 in the BWC and 24 in the AWC, thus the health was turned to be "B-Rank" in the BWC and "C-Rank" in the AWC. indicating a degradation of ecological heath after the weir construction.

  • As a result of the current trend towards promoting conservation of the ecosystem, there have been various studies conducted to determine ways to establish an ecological network. The development of analytical methods and an environmental database of GIS has made the creation of this network more efficient. This study focuses on the development of an urban spatial decision support system based on 'Landscape Ecology Theory'. The spatial decision support system suggested in this study consists of four stages. First, landscape patch for the core areas, which are major structures of the ecological network, was determined using the GIS overlay method. Second, a forest habitat was investigated to determine connectivity assessment. Using the gravity model, connectivity assessment at the habitat forest was conducted to select the needed connecting area. Third, the most suitable corridor routes for the eco-network were presented using the least-cost path analysis. Finally, a brief investigation was conducted to determine the conflict areas between the study result and landuse. The results of this study can be applied to urban green network planning. Moreover, the method developed in this study can be utilized to control urban sprawl, promote biodiversity.

  • The wetlands are facing environmental changes such as desiccation that occurs with the passage of time and reduced ecosystem services from wetlands in the city. In order to maintain the ecosystem services provided by wetlands in urban areas, a system thinking about the trade-off phenomenon of ecosystem services occurring as the wetlands undergo environmental changes is needed. Therefore, the purpose of this study is to develop strategies for wetland design using system thinking approach to enhance the resilience of ecosystem services degraded by the desiccation of wetlands and other disturbances. The objectives of this study include the system boundary and variables. Second, analyzing the dynamics of wetland design strategy. Third, it analyzes the trade-off phenomenon of ecosystem services in terms of the hydrology, hydric soil, and plants strategies to mitigate these effects. Fourth, wetland basic design to improve the resilience of ecosystem services. A wetland in Abuk-Mountain Neighborhood Park, Miryang-si, Gyeongsangnam-do, has been selected as a case study. Causal loop diagrams(CLDs) are used to analyze feedback in the wetland regime. In summary, hydrology, hydric soil, and plants is suggested as system boundaries to design plan. Design strategies for the wetland focused on robustness, redundancy, rapidity, and resourcefulness as a result of CLD analysis are first proposed in order to effectively maintain the wetland regime over the long term. Secondly, in a section related to hydrology, the CLD results show the trade-offs between provisioning-cultural services and regulating services. In order to control these services, a "water cycling system" has been implemented due to its strength in terms of robustness. The CLDs for hydric soil showed the trade-offs between regulating services and supporting services. An "installation of storm drainage for maintaining water levels" was selected due to the strength offered in terms of redundancy and rapidity. The CLDs for plants showed the trade-offs between provisioning - cultural services and regulating services. In order to control the strategic points, the "planting of indigenous vegetation" was suggested given the strength in terms of redundancy. In this study, a wetland design method is proposed that can improve the resilience of wetland ecosystem services by analyzing the dynamics overtime. The results of this research can theoretically be applied to help restore ecosystem services in wetlands using ecological landscape design. In addition, this study will contribute to reducing maintenance costs by improving wetland resilience.

  • How to see nature and how to define the relation between nature and the human certainly influence fundamental attitude toward nature and any results derived from the attitude. Therefore, in order to figure out a way for how the humans and nature should coexist, the thesis has began a philosophical analysis on the origin of the biomimetics. Based on findings from the analysis, the thesis would work on the features of biomimicry space, presenting related possibilities. For the philosophical characteristic of the thesis which was an ecological world view, introduced at the end of mechanical world view era, the ideas of Spinoza, Nietzsche, Bergson and Deleuze about nature were quoted. Based on what the philosophers have said, the thesis looks into successful ideas, designs and ways of living that nature has shown by itself. After all, the purpose of the thesis is to investigate the constantly changing space of the biomimetics by organic forms, autonomous systems and dividing programs. Based on this, nine cases were analyzed to derive the characteristics. As a result, organic forms, autonomous systems and dividing programs characteristics of ecological appear simultaneously in harmony. Biomimicry space can coexist with nature and the human is an effective way.

  • The fields of green building and ecological design have much to offer to those who are seeking to improve the ecological impact of schools and school grounds. These well established disciplines are particularly useful to existing schools considering renovations to make them more energy, water, and resource efficient as well as healthier places to work and play, Green building and ecological design principles and techniques are also very effective, of course, if incorporated into the design for brand new school buildings. The major concept of the Eco-school plan is to understand that the school consists of an ecosystem, so the design concept should focus on minimising impact but at the same time maintaining close contact with the environment. T his is becoming the basic concept in applying the Eco-school design to the new 21st century school building. This thesis is an analysis on the methods of application, based on careful examination of case-studies from the U.S.A about detailed plan element and design method, through the following six aspects ; (1) site use plan, (2) green plan, (3) water system plan, (4) materials and recycling of resources, (5) energy use plan, (6) indoor environment plan.

  • We tried to analyze qualitatively a total of 110 the research papers which were related domestic ecological restoration technologies about 15 years through semantic network analysis in social network analysis. In order to understand the research trends of ecological restoration technologies, we analyzed the degree centrality and betweenness centrality of the Stream/Wetland, Slope, Soil/Others fields selected as Word Cloud. As a result, ecological restoration technologies have been changed. They were focused on the restoration of species or their habitats in the past. However, they have been evolved into the detailed systems to respond in unpredictable natural disasters and climate change, high-resolution image implementation technology to accurately grasp the practical environment and methods related to environmental restoration for human in urban ecosystem. In the future, investment and technology for the ecosystem restoration field will be continuously demanded for the symbiosis of human beings and species in the damaged ecosystem. Therefore, the research trend of ecological restoration technologies should be provided as reliable guidelines when decision makers establish the policy direction or when researchers select their subjects.

  • Over the years, there have been many school construction projects resulting from the activation of the Build Transfer Lease(BTL). Furthermore, due to the need for the qualitative expansion of educational facilities, as well as the attempt to fulfill social requirements and the need for eco-friendly learning environments, these projects have become a major priority. As a result, the government has established a proper standard for school construction based on a certain level of green certification that has been mandated. The aim of this study is to assess the status of schools as relates to the composition of the ecological environment surrounding them. These elements of eco-friendly school facilities are larger than the educational environment and are directly related to the environmental and educational effects on the students. Looking at the overall results of this study, the areas of ecological environment outside school are found to be inadequate. Therefore, this field needs to adopt more realistic goals, and focus on the areas where the most improvement is needed.
