Ecosystem service values have rarely been incorporated in the process of planning ecological infrastructure for urban areas. Urban ecological infrastructure is a network system of natural lands and waters that provides ecosystem services. The purpose of this study was to design landscape corridors that maximize the value of ecosystem services in ecological infrastructure planning. We explored the optimal corridors to enhance the connectivity among landscape elements to design an ecological infra

The dynamics of land-use transitions decrease the coastal resilience of the social-ecological landscape (SEL), particularly in light of the fact that it is necessary to analyze the causal relationship between the two systems because operations of the social system and the ecological system are correlated. The purpose of this study is to analyze the dynamics of the coastal SEL and create a sustainable land-use planning (SLUP) strategy to enhance coastal resilience. The selected study site was Shi

Greenways provide multiple benefits for trail users’ individual experiences based on users’ background environment and their perceptions of characteristics such as the trail width, vegetation, water, and facilities. Although greenway trail characteristics are important factors that affect users’ preferences, only a few studies have examined individuals’ experiences of greenways based on their perceptions and preferences. The purpose of this study is to examine how greenway trails can be designed

As climate change-induced weather variability increases, various green infrastructure plans, such as stream ecosystems, have been studied to overcome ecological and environmental problems arising from extreme weather events; however, our understanding of them and their resilience to extreme weather events is considerably limited. This study proposes a multicriteria inventory classification while planning green infrastructure for resilient stream ecosystems under extreme weather events. Literatur

An ecotourism system that is based on wildlife habitats in ecological systems is considered a social-ecological system that has a feedback relationship with social systems. Increases in socioeconomic activities and tourism infrastructure construction are not conducive to the resilience of wildlife habitats, thereby stressing the ecological system and threatening sustainable ecotourism. Managing resilient wildlife habitats by developing transformation plans that can be used to construct new syste

본 연구는 도시 소공간의 열환경을 개선하기 위한 방안을 모색하고자 공간 구조별 열특성을 평가하여 분석하였다. 도심 내 위치한 고려대학교 캠퍼스를 연구 대상지로 선정하였으며, 대상지 내에 공간 유형을 대표하는 각각의 장소에서 열환경을 조사하였다. 기상장비를 활용한 미기상 및 바이오 기상 측정, 어안렌즈 촬영사진(Fish-eye lens photography)를 활용한 공간구조 및 특성 분석, 그리고 온도나 습도와 같은 기상정보 및 이미지 정보를 활용한 열쾌적성 모델링의 순서로 공간의 열환경 및 인체 열쾌적성을 분석하였다. 열환경 평가 결과, 인체 열쾌적성의 정도는 캠퍼스 공간의 유형에 따라 차이가 나타났다. 건물이나 수목 등에 의해 위요된 폐쇄형 공간 유형에서 개방형 공간 유형에서 분석된 평균 복사온도, PMV, PET 지수보다 더 양호한 것을 알 수 있었다. 이러한 결과는 수목과 건물에 의한 태양복사열의 차단 및 그림자의 영향을 받기 때문이라고 할 수 있다. 그러므로 공간을 계획할

Resilience is being widely adopted as a comprehensive analytical framework for understanding sustainability dynamics, despite the conceptual challenges in developing proxies and indicators for researchers and policy makers. In our study, we observed how the concept of resilience undergoes continued extension within the rural resilience literature. We comprehensively reviewed rural resilience literature using keyword co-occurrence network (KCN) analysis and a systematic review of shortlisted pape

선진국에서 1970년대 말부터 주목받기 시작한 신 빈곤의 한 양상인 ‘빈곤의 여성화(feminization of poverty)' 현상은 IMF 경제위기 이후 우리사회에서도 관측되어 왔다. 빈곤의 여성화 현상은 국내외적으로 여성가구주 가구의 증가라는 가족구조의 변화와 서비스 부문의 확대, 노동유연화 추구 등의 경제구조 변화가 맞물려 촉발되었는데, 그 추세는 지속되거나 오히려 강화되고 있다. 본 연구에서는 빈곤의 여성화의 추세와 그 요인을 분석하는데 금재호․김승택(2001)이 제시한 ‘항상빈곤(permanent poverty)' 개념을 이용하였다. 빈곤을 경험한 가구의 절반 이상이 빈곤을 되풀이 경험한다는 기존의 연구(이병희․정재호, 2002)에서도 알 수 있듯이 많은 빈곤가구가 빈곤한 상태로부터 영구한 탈출을 하는데 어려움을 겪는다. 따라서 장기간에 걸친 ‘평균소득’이 빈곤선 이하이면 빈곤한 가구 혹은 개인으로 보는 항상빈곤 개념을 이용하면 빈곤의 실태에 대한 윤곽이 더 잘 드러

Ecosystem services depend on the interrelation between people and the environment, and people are increasingly recognizing the social value of ecosystem services. Based on humans needs related to the values of ecosystem services, riparian greenways, properly planned and managed for resiliency, could provide great opportunities for social ecological change and transformation toward sustainability. We focus on the ecosystem service values of such greenways based on resilience in urban communities.

Purpose: Distant metastasis and recurrence are major prognostic factors associated with breast cancer. Both lymphovascular invasion (LVI) and blood vessel invasion (BVI) are important routes for metastasis to regional lymph nodes and for systemic metastasis. Despite the importance of vascular invasion as a prognostic factor, application of vascular invasion as a histopathological criterion is controversial. The aim of this study was to distinguish LVI from BVI in prognosis and recurrence of brea

This paper presents an integrated approach to mitigation wetland site selection using functional landscape connectivity and landscape structure. This approach enables landscape designers to evaluate the relative priorities of mitigation wetland areas based on functional landscape connectivity and wildlife mobility, as well as landscape structure, composition, and configuration. The least-cost path method is used to evaluate candidate sites for mitigation wetlands with regard to wildlife movement
