This study suggests the methods of the assessment and creation of biotopes in small and medium sized cities, in Korea. For this purpose, Chonju city was selected to classify and asses the biotope types. Moreover, relevant legislations to conserve and enhance urban biotopes were examined. The results of this study are as follows: 1) There were two approaches to asses the potential of urban biotopes in medium-sized cities. One was the urban scale evaluation for urban green spaces and the other was the biotope scale evaluation for the classification and evaluation of biotopes. 2) The urban scale evaluation was developed through overlaping analysis of landuse and vegetation factors. This study also included the conception of watershed. In this conception, three watersheds in Chonju city were characterized. According to these characteristics, individual programs for conservation and enhancement of urban green space were suggested. 3) For the biotope scale evaluation, Selected site was inclusively mapped and field investigation actually was carried. There were total 9 types of bitopes. Especially landuse was appeared in various evaluation items were vegetation structure, area of green space, condition of vegetation and vegetation profile. Mt, Gonji and Dukjin park, Chonbuk national University and fields were evaluated highly I the potential. 4) The biotope programs were based on the results of assessment and physical characteristics of biotopes. The uniform and simple levels on vegetation must be modified with various levels of vegetation structure and vernacular plants. And the physical characteristics like Points, Corridors and Patches can be organized by the conception of biotope networking theory. 5) The proper legislative environment was the clue elements for the biotope programs. Until now, only five types of parks and two types of green space are defined and the minimum size of green space has been proposed by the law. So, it is necessary to enlarge the conception of green space in legislation and improve the quality of green space by amending the related regulations. This study has limitation because it was selected only in Chonju. Through the continuous studies, we need to apply this other small and medium sized cities, South Korea. Also the data collection and management of theme maps such as actual vegetation, landuse and a soil must be done preliminary.

The problem of the population number of honeybees that is decreasing not only domestically but also globally, has a great influence on human beings and the entire ecosystem. The habitat of honeybees is recognized to be superior in urban environment rather than rural environment, and predicting for habitat assessment and conservation is necessary. Based on this, we targeted Cheonan City and neighboring administrative areas where the distribution of agricultural areas, urban areas, and forest areas is displayed equally. In order to predict the habitat preferred by honeybees, we apply the Maxent model what based on the presence information of the species. We also selected 10 environmental variables expected to influence honeybees habitat environment through literature survey. As a result of constructing the species distribution model using the Maxent model, 71.7% of the training data were shown on the AUC(Area Under Cover) basis, and it was be confirmed with an area of 20.73% in the whole target area, based on the 50% probability of presence of honeybees. It was confirmed that the contribution of the variable has influence on land covering, distance from the forest, altitude, aspect. Based on this, the possibility of honeybee's habitat characteristics were confirmed to be higher in wetland environment, in agricultural land, close to forest and lower elevation, southeast and west. The prediction of these habitat environments has significance as a lead research that presents the habitat of honeybees with high conservation value of ecosystems in terms of urban space, and it will be useful for future urban park planning and conservation area selection.

Nowaday special attention is being paid to the conservation of all species or ecosystmes of sites for public projects. Many environmental conservation policies and projects in Japan emphasize the coexistence of man with nature and close contact with nature. The objectives of this study was to investigate policies and projects for the creation of areas for the close contact with nature in Japan, to characterize change of techniques for the space creation over times, and to classify those policies and projects implemented by many government agencies. This study was mainly carried out by literature survey of laws, policies and projects related to environmental conservation pertinent to national scale. Major findings of this study can be summarized as follows: First, two most significant turning points for the environmental conservation in Japan were the establishment of the Office of Environmental in 1971 and the enactment of many laws influenced by the awareness of global environmental problems since 1990. Second, polices and projects for the creation of areas for the close contact with nature started in 1960s by the Office of Forestry, and focused on planting and development of simple facilities in forests. And the conservation of natural environment, ecological restoration and the expansion of urban green spaces, and the creation of biotopes and other areas for the close contact with nature in urban areas were the major characteristics of environmental conservation in Japan during 1970s, 1980s, and 1990s, respectively.

Building energy consumption takes up almost 25% of the total energy consumption. Therefore, diversified ways, such as improving wall and window insulation, have been considered to reduce building energy consumption. Recently, green roof system has been explored as an effective alternative for dealing with reducing heating and cooling energy, thermal island effect and improving water quality. However, recent studies regarding a green roof system have only focused on building energy reduction without considering the applied usage, location, and story of the green roof system. Therefore, this study pays attention to the heating and cooling energy in relation to the applied usage, location, and story of a green roof system for investigating its impact on energy reduction. The result of simulations show that the reduction in heating energy consumption is higher when applied to Cherwon-gun province which has a continental climate condition, compared to the city of Busan that is distinguished by its warm climate. Cooling energy saving turns out to be higher when the green roof system is applied to Busan in comparison with Cherwon. As for the applied usage or function of the building, residential space acquires the highest heating and cooling energy saving effect rather than commerce, educational or office space because of HVAC's running time based on usage. When it comes to the story of the green roof, both heating and cooling energy saving become the highest when the green roof is applied to single-storied buildings. The reason is that single story building is affected by the ground largely. Generally, the variations of heating energy consumption are larger than the cooling energy consumption. The outcome of the simulations, when a green roof system is applied, indicates that the energy consumption reduction rate is dynamically responding to the applied usage, location, and story. Therefore, these factors should be counted closely for maximizing the reduction of energy consumption through green roof systems.

본 연구는 2020년 장기미집행 도시공원의 자동실효(이하 도시공원 일몰)로 인한 생태네트워크 측면에서의 영향을 부산지역을 대상으로 분석하였다. 분석은 도시공원 일몰과 관련하여 가능한 5개의 시나리오를 구축하고 각 시나리오별 생태네트워크 변화를 FRAGSTATS의 경관지수들을 활용하여 살펴보았다. 일몰 예정 공원에 대해 전체 개발을 가정하는 시나리오 1은 해당 공원들의 전체 보전을 가정한 시나리오 5에 비해 녹지면적이 7,339.75ha가 감소하고, 생태공간의 파편화도 증가하는 것으로 분석되었다. 내부종 서식지에 영향을 미치는 중심지 비중도 8.06%이상 감소되며, 녹지 간 연결성도 28.23% 이상 감소되는 것으로 나타났다. 그러나 공원 내 생태적 가치가 높은 지역을 중심으로 보전하는 것을 가정하는 시나리오 3은 시나리오 5(전체 대상지 보전)의 94% 지역에 대한 보전이 가능하며, 연결성 측면에서는 95.6% 이상 보완이 가능할 뿐 아니라 생태지역 파편화 측면에서도 공원예정지 전체를 조성하는 것과 유사한 효과가 나타나고 있었다. 따라서, 일몰 예정 공원에서도 보전가치가 높은 지역을 중심으로 보전하는 것은 생태네트워크 측면에서 효과가 상당히 높음을 확인할 수 있었다. 현재 지자체에서 이들 보전지역을 중심으로 우선 해제를 시행하고 있는데, 이들 지역은 개발의 수준이 낮다고 해도 산발적 개발가능성이 높으므로 현재 추진 중인 우선 해제에 대한 재고가 필요하다고 판단된다.

Given the anisotropic Poisson equation $-{\nabla}{\cdot}{\mathcal{K}}{\nabla}p=f$, one can convert it into a system of two first order PDEs: the Darcy law for the flux $u=-{\mathcal{K}{\nabla}p$ and conservation of mass ${\nabla}{\cdot}u=f$. A very natural mixed finite volume method for this system is to seek the pressure in the nonconforming P1 space and the Darcy velocity in the lowest order Raviart-Thomas space. The equations for these variables are obtained by integrating the two first order systems over the triangular volumes. In this paper we show that such a method is really a standard finite element method with local recovery of the flux in disguise. As a consequence, we compare two approaches in analyzing finite volume methods (FVM) and shed light on the proper way of analyzing non co-volume type of FVM. Numerical results for Dirichlet and Neumann problems are included.

This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.
