  • 현대사회가 당면한 다양한 문제를 해결하는 주체로 '제4섹터(the fourth sector)'가 주목받고 있다. 제4섹터는 사회적경제 기업으로 대표되는 제3섹터의 지나친 정부 의존도와 서비스 모델 동형화의 문제점을 해결하고자 등장하였다(Meadows, 1972; Howaldt and Schwarz, 2010). 이러한 제4섹터의 핵심 주체로서 소셜벤처가 언급되고 있다(경기연구원, 2018). 그러나 아직까지 소셜벤처에 대한 학술적 및 정책적 개념이 모호한 실정이다. 따라서 본 연구에서는 사회의 포용적 성장을 도모하기 위해 제4섹터로서의 소셜벤처 정의와 특성을 명확히 하고, 소셜벤처 생태계 활성화를 위한 발전전략을 연구하고자 한다.

  • The purpose of this study was to explore the structure and content of chemistry teacher's explanations from the perspective of 'persuasion'. Especially, this study was to explore how the argument structure and the conceptual change constructs in chemistry teachers' explanations were established and interacted. Data were collected from chemistryI classes considering the gas unit which includes kinetic theory of gas, Graham's law, Boyle's law, and Charles' law. The classes were vediotaped and transcribed. The transcriptions were analyzed with Toulmin's argument frame and the two constructs of conceptual change model; the conceptual ecology and the status of a conception to interpret the persuasive structure and content of the teacher's explanations. As the results of this study, four explanatory discourses which show various persuasive explanations in chemistry classes. Based on this results, discussion and implications for effective teachers' explanations in chemistry classes were presented.

  • Integration system of conservation ecology, ecosystem management and land planing in landscape scale is major principle strategy for national management system of environmental resource and biodiversity. Current conservation strategy is concerned with not only population and habitat level but also ecosystem and landscape level. In especially, ecological networking to link core areas or major habitat patches is most eminent and emerging issue in European Union (EU) and North America. Moreover, the promotion of national ecological network system in EU is focused on national cooperation to construct ecological corridor for key habitat that distributed in many countries. Integrating landscape ecology into conservation ecology and restoration have important role to stimulate the network system in regional and national level. In this review paper, comprehensive and necessary considerations arisen from the view of landscape ecology were discussed for the present situations of wildlife conservation and management in Korea compared with other countries. Especially, the conservation strategy and policy of biodiversity were addressed in broad sense including habitat protection, legal approaches, and ecological network programs. Finally, a national ecological network system was suggested for environmental policy in Korea in global consideration after the Korean Unification.

  • The concept of carrying capacity for bivalve culture of an area can be classified into four hierarchical categories, according to their level of complexity and scope, such as physical, production, ecological and social carrying capacity. Most scientific efforts to date have been directed towards modelling production carrying capacity and some of the resultant models have been used successfully. But, the modelling of ecological carrying capacity is still in its infancy, because it should consider the whole ecosystem and all culture activities. A more holistic approach is needed to determine the influence of bivalve aquaculture on the environment and ecological carrying capacity. As an alternative, we can use a set of ecological indicators which can show the environmental performance of bivalve farms and assess ecological carrying capacity. Clearance efficiency and filtration pressure indicators show the value of 0.331 and 0.203, respectively, and these indicators suggest that the present level of culture in GeojeHansan Bay is above the ecological carrying capacity of 0.05. Consequently, these indicators can provide a guidance on the present level of culture in regard to production and ecological carrying capacity in GeojeHansan Bay.

  • Since the late 20th century, sustainability is one of the most pressing concerns for the security and well-being of our society when we are witnessing the rapid change in urban landscape patterns. Responding to this issue, the discipline of environmental designs including landscape architecture has also attempted to realize this concept in various ways. The purpose of this study lies in introducing and redefining the meaning of ecological aesthetics as an alternative "sustainable" design theory. This paper theoretically discusses about the role of aesthetics in landscape design and the relationship between landscape and aesthetics to emphasize the importance of ecological aesthetics. Based on extensive literature review and analysis, the study attempts to redefine the characteristics of ecological aesthetics: an emphasis on cognitive process in landscape appreciation, environmentalism, unrestricted from style, and nonnative aesthetics. Having defined the characteristics, this study also finds several design subjects to adapt the concept of ecological aesthetics to actual design practice. Founded on the big idea "make nature visible", the defined subjects are ecological functions, temporality of landscape, and history of landscape, security, and accessibility. Also, this study stresses the importance m the creativity of the design(er) in order to effectively represent these subjects to the public.

  • 통합수자원의 관리(IWRM)에 대한 명확한 용어의 기원과 정의는 내려져 있지 않으나, 1992년 더블린에서 열린 물과 환경에 대한 국제 컨퍼런스에서는 통합수자원관리에 적합한 가이드라인 성격의 원칙을 정하였다. 또한 GWP(2000)는 '생태계의 근본을 지키면서 최대한의 사회, 경제적 가치 창출을 위한 물과 육지, 그리고 이와 관련된 자원을 관리하고 개발하는 과정'으로 통합수자원관리에 대한 일반적인 정의를 내리고 있다. 한편 우리나라에서 하천유지유량의 개념이 문서상으로 나타나기 시작한 것은 1960년대이며, 1995년에 그 구체적인 산정방법이 정립되었고, 1999년 전국 4대강 수계의 하천유지유량이 산정되었다. 이 값들은 2006년 60개 지점에 대해 고시되었으며, 같은 해 환경개선용수의 개념이 정립되고 2007년 개정된 하천법에 보완된 하천유지유량의 개념이 출현 하였다. 하천유지유량 산정방법 또한 보완되어 2007년부터 금강권역을 시작으로 하천 유지유량 재 산정 작업이 시작되어 현재 진행되고 있다. 해외의 경우 1990년대 중반 호주와 남아프리카공화국, 미국 등에서는 하천생태계, 특정 유량이 아닌 전체적인 변동성(유황)을 중요시하는 환경유량의 개념이 정립되어 활발히 연구되고 있다. 본 연구에서는 통합수자원관리와 우리나라의 하천유지유량 및 환경개선용수, 그 중요성이 더욱 강조되고 있는 환경유량의 관계를 살펴보고 향후 하천수 관리에 대한 방향성을 제시하였다.
