본 연구는 미국 외부공간의 지속가능성 인증지표 가운데 물과 토양 및 식생 평가항목의 필수 및 핵심지표를 심층적으로 검토하여 우리나라의 관련 법 제도적 지침과 기준의 관점에서 비교, 고찰함으로써 실제적인 적용을 위한 관련 내용과 절차, 시사점을 도출하였다. 미국 외부공간의 지속가능성 인증시스템의 경우에 관련된 법제도적 지침 및 기준과 연계되어 있으나 시행의 절차는 민간차원의 독립된 평가시스템으로서 생태계 서비스의 핵심요소인 물과 토양+식생 평가항목의 경우 자연지반의 보전을 전제로 지속가능한 물 순환 및 자생식물의 보전과 활용을 위한 표준화된 정량적 기준의 적용이 특징적이었다. 반면 우리나라의 경우 국가차원의 법 제도적 절차에 따른 녹색건축의 인증기준의 한 부문으로서 생태면적율 제도는 인공녹지의 조성을 통한 어메니티자원 확보 차원, 그리고 물 순환관리시스템의 미흡 등으로 매우 제한된 역할에 머물러 있는 수준이었다. 따라서 국가차원에서 다양한 토지의 용도 및 개발사업 유형에 따른 물순환과 자연지반의 토양 및 식생의 조성관리를 기반으로 한 통합적이고 실효성 있는 외부 공간의 지속가능성 평가체계 구축이 매우 시급한 것으로 판단되었다.

The objectives of this research were to predict land-use/land-cover change at the Sakaerat Environmental Research Station (SERS) and to analyze its consequences on the distribution for Black-crested Bulbul (Pycnonotus melanicterus), which is a popular species for bird-watching activity. The Dyna-CLUE model was used to determine land-use allocation between 2008 and 2020 under two scenarios. Trend scenario was a continuation of recent land-use change (2002-2008), while the integrated land-use management scenario aimed to protect 45% of study area under intact forest, rehabilitated forest and reforestation for renewable energy. The maximum entropy model (Maxent), Geographic Information System (GIS) and FRAGSTATS package were used to predict bird occurrence and assess landscape fragmentation indices, respectively. The results revealed that parts of secondary growth, agriculture areas and dry dipterocarp forest close to road networks would be converted to other land use classes, especially eucalyptus plantation. Distance to dry evergreen forest, distance to secondary growth and distance to road were important factors for Black-crested Bulbul distribution because this species prefers to inhabit ecotones between dense forest and open woodland. The predicted for occurrence of Black-crested Bulbul in 2008 covers an area of 3,802 ha and relatively reduces to 3,342 ha in 2020 for trend scenario and to 3,627 ha for integrated-land use management scenario. However, intact habitats would be severely fragmented, which can be noticed by total habitat area, largest patch index and total core area indices, especially under the trend scenario. These consequences are likely to diminish the recreation and education values of the SERS to the public.

In the recent years, the incidence of abandoned concrete roads have been increasing rapidly due to road improvements and facilities route construction, these abandoned expressway and unused roads are scattered throughout the country but the management system is not clear, they does not be an effectively managed because there is no maintenance cost. In response to these social concern and expectation, the Korea Expressway Corporation that is management authority of the expressway is developing policy initiatives and various projects to restore the closed road to ecological for eco-friendly projects of the existing expressway. And as part of these projects, Hwanggan IC unmanaged abandoned concrete roads restoration project was done and it was conducting monitoring for ecological restoration that is not one-off but sustainable. After test construction over seven years at the time, test construction of four ways enforced but the boundaries have become blurred over time. And Pinus koraiensis, Callicarpa dichotoma and Sorbaria stellipilla var. typica planted in the site are dominating, else Amorpha fruticosa and Indigofera pseudotinctoria sowed are dominating. Invasive species is that Robinia pseudoacacia was growing in the colony. Over monitoring result time, the vegetation was taking root and the ecosystem was being restore. But the disturbance of vegetation happens due to planting of tree species that doesn't fit in the restoration area and advent of ecosystem Disturbing Species. The study will be providing a basic data that identify change of plant environment by monitoring of the site and soil environment during June to November 2016 and secure an objective evaluation data by analyzing the effects of ecological restoration for revegetation test bed evaluation for ecological restoration of expressway in ecological restoration construction in later.

The purpose of this study is to identify effect in how urban garden is run by different operators in Korea, and consequently how it determines the level of community formation among urban garden users. Based on this analysis, the study is intended to present some points as to how to better manage urban garden. The operators are divided into three types: public, public-private partnership and private. The study interviewed each operating entity and surveyed garden users to gauge the extent to which communities are developed. After the ANOVA analysis and Scheffe post-hoc analysis, it was found that the levels of community formation among users of public and public-private partnership urban gardens were similar (so can be grouped together), whereas that of private urban garden users was higher (separated as another group). However, this study found no meaningful differences in the level of community formation among all types of urban garden in a local community. Some key suggestions are made as a result. First, as for the public and public-private partnership types of urban garden, it is necessary to foster leaders to build a community. Next, it is worth noting the potential of public-private partnership in realizing community revival through urban garden. The last suggestion is that, generally, the urban garden has only little influence on community formation in a local area so far, thus more practical consideration needs to be given to enhance the role of urban garden in a local community.

This study aims to provide basic understanding for evaluating the quantitative and qualitative progress of national protected areas, through the theoretical review of Aichi Biodiversity Target 11 in order to comply with recommendations of international community and to conserve biodiversity. As a result of the study, Aichi Biodiversity Target 11 sets out the specific contents that the Parties should achieve for protected areas by identifying them as temporal and spatial goals. The temporal goal, the time schedule for achieving the goal, is 2020, and the spatial goal is divided into quantitative expansion goals and qualitative improvement goals. The quantitative expansion goals present the target coverage of protected areas separately terrestrial and marine. The qualitative improvement goals include the target areas for conservation and five conservation considerations. The conservation targets focus on the important areas with regard to biodiversity and ecosystem services. The five conservation considerations mean effective management, equitable management, ecological representativeness, connectivity, and integration into the landscape and seascape for protected areas. Finally, it suggests that two tracks of protected areas and other effective area-based conservation measures(OECMs) should be used as conservation measures to build an integrated system. The results of this study can be applied to quantitative and qualitative evaluation methods for protected areas and it can contribute to achieve quantitative expansion goals and qualitative improvement goals for them.

This study is to enhance the provincial leisure plans through various programs and infrastructure facilities and to establish a network of natural leisure areas in Gyeonggi-do. According to the result, first, in terms of analyzing the locations of natural leisure areas by types, the rest of urban parks is formed in the Capital area outside Seoul as centering around the central area. Moreover, with regard to the rest of forest and the rest of natural ecology learning, the area of the detention exceeds the total area of Gyeonggi-do. The rest of valleys and swamps showed a dotted pattern of the detention area while the rest of tideland and fishing village experience indicated a distribution of the detention area along the West Coast as an axis. Second, according to result of analyzing the accessibility of natural leisure areas by types, the rest of valleys and swamps showed the highest accessibility among the natural leisure areas : the rest of natural ecology learning had the medium level of accessibility; the rest of forest indicated the lowest accessibility. Therefore, it is necessary to create more leisure areas concerning the futures demands. In addition, they should be constructed in the places adjacent to the urban district area exhibiting higher usability and accessibility. In the places where there are many natural leisure area with higher utility, management plans should be deliberated as well. Based on the result of analyzing the rest of valleys and swamps and the rest of tideland and fishing village experience, it was found that the natural leisure area should improve the quality of water intensively and hydrophile property and create hydrophilic spaces. The development of natural leisure areas need to be carried out under the principle of environmental protection while considering historic sites and nearby rivers and lakes. Moreover, water leisure programs should be developed actively as well with further utilization of water resources in order to enhance the usability of natural leisure.

Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM₁₀ concentrations were converted to weight for demand assessment on PM₁₀ reduction, and PM₁₀ absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM₁₀ absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM₁₀ in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM₁₀ and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

Since the Global Financial Crisis of 2008-2009, the importance of nonbank financial institutions in macroprudential management has increased significantly. Consequently, major countries and international financial institutions have been actively discussing and implementing macroprudential supervision and regulation for non-bank financial institutions (NBFI). In this context, this paper analyzes the systemic risk of both banks and non-bank sectors (securities firms and insurance companies) in South Korea over different time periods. Using the widely recognized ΔCoVaR methodology for measuring systemic risk, the analysis reveals that systemic risk increased substantially across all three sectors (banks, securities firms, and insurance companies) during the Global Financial Crisis, the European Sovereign Debt Crisis, and the COVID-19 pandemic. Although the banking sector exhibited relatively high systemic risk compared to the securities and insurance sectors, the relative differences in systemic risk varied across the different crisis periods. Notably, during the margin call crisis in March of 2020, the gap in systemic risk between the banking and securities sectors decreased significantly compared to that during both the Global Financial Crisis and the European Sovereign Debt Crisis, indicating that securities firms had a more substantial impact on risk in the overall financial system during this period. Furthermore, I analyze the impact of the issuance of equity-linked securities (ELS) by financial institutions on systemic risk, as measured by ΔCoVaR, finding that an increase in the outstanding balance of ELS issuance by financial institutions had an impact on increasing ΔCoVaR during the three crisis periods. These findings underscore the growing importance of non-bank financial institutions in relation to South Korea's macroprudential management and supervision. To address this evolving landscape, enhanced monitoring and regulatory measures focusing on non-bank systemic risk are essential components of maintaining financial stability in the country.
