The Bayesian algorithm model is a model algorithm that calculates probabilities based on input data and is mainly used for complex disasters, water quality management, the ecological structure between living things or living-non-living factors. In this study, we analyzed the main factors affected Korean Estuary Trophic Diatom Index (KETDI) change based on the Bayesian network analysis using the diatom community and physicochemical factors in the domestic estuarine aquatic ecosystem. For Bayesian analysis, estuarine diatom habitat data and estuarine aquatic diatom health (2008~2019) data were used. Data were classified into habitat, physical, chemical, and biological factors. Each data was input to the Bayesian network model (GeNIE model) and performed estuary aquatic network analysis along with the nationwide and each coast. From 2008 to 2019, a total of 625 taxa of diatoms were identified, consisting of 2 orders, 5 suborders, 18 families, 141 genera, 595 species, 29 varieties, and 1 species. Nitzschia inconspicua had the highest cumulative cell density, followed by Nitzschia palea, Pseudostaurosira elliptica and Achnanthidium minutissimum. As a result of analyzing the ecological network of diatom health assessment in the estuary ecosystem using the Bayesian network model, the biological factor was the most sensitive factor influencing the health assessment score was. In contrast, the habitat and physicochemical factors had relatively low sensitivity. The most sensitive taxa of diatoms to the assessment of estuarine aquatic health were Nitzschia inconspicua, N. fonticola, Achnanthes convergens, and Pseudostaurosira elliptica. In addition, the ratio of industrial area and cattle shed near the habitat was sensitively linked to the health assessment. The major taxa sensitive to diatom health evaluation differed according to coast. Bayesian network analysis was useful to identify major variables including diatom taxa affecting aquatic health even in complex ecological structures such as estuary ecosystems. In addition, it is possible to identify the restoration target accurately when restoring the consequently damaged estuary aquatic ecosystem.

본 연구는 국내 창업초기투자생태계의 현황을 진단하고 향후 진화의 방향과제를 도출하는 것이 목적이다. 2013년 정부의 투자중심 창업지원 생태계 구축정책에 힘입어 국내 창업초기 투자생태계는 보다 세분화되고 활성화 되고 있다. 종전의 엔젤투자와 VC 투자자로 양분되었던 벤처투자시장에, 특히 창업초기단계 개인엔젤투자조합, 전문엔젤, TIPS, 엑셀러레이터와 창업초기 전용VC 펀드인 인큐베이팅펀드와 청년창업전용투자펀드등에서 최근 마이크로VC펀드에 이르기까지 다양한 창업초기 VC 펀드가 창출되며 다양한 그룹의 투자자들이 생성 진화중이다. 이렇게 창업초기 다양한 투자자그룹이 생성되고 성장하고 있는 이면에는 정부의 매칭투자와 투자연계 R&D 자금이 큰 역할을 하고 있어 투자자들에게는 창업기업에게 Valuation과 투자 위험 관리에 큰 도움을 주고, 창업기업에게는 과도한 지분의 희석 없이 투자자금이 가진 장점의 혜택을 극대화하고 있다. 그러나 본 연구의 국내창업초기 투자생태계 진단결과, 국내 창업투자생태계는 다양한 투자자그룹이 생성되고 성장하고 있지만 서로 다른 투자자 그룹 간 공동투자나 후속투자 연계 등의 협업적 활동 및 회수네트워크 연계 등 활동은 아직 미흡하다. 또한 투자분야 자체가 모바일 및 인터넷서비스 분야에 집중되고 있어, 상대적으로 긴 시간의 보육과 성장검증기간 및 규모 있는 투자를 필요로하는 제조분야는 비중이 약한 편이어서 투자 대상 사업 분야의 다변화 필요하다. 뿐만 아니라 국내 창업초기투자생태계는 창업의 글로벌 사업성과를 내기 위한 글로벌 투자자들과의 연계구조는 미흡한 상황이어 이를 촉진할 방안이 요구된다고 할 수 있다.

KoFlux is a Korean network of micrometeorological tower sites that use eddy covariance methods to monitor the cycles of energy, water, and carbon dioxide between the atmosphere and the key terrestrial ecosystems in Korea. KoFlux embraces the mission of AsiaFlux, i.e. to bring Asia's key ecosystems under observation to ensure quality and sustainability of life on earth. The main purposes of KoFlux are to provide (1) an infrastructure to monitor, compile, archive and distribute data for the science community and (2) a forum and short courses for the application and distribution of knowledge and data between scientists including practitioners. The KoFlux community pursues the vision of AsiaFlux, i.e., "thinking community, learning frontiers" by creating information and knowledge of ecosystem science on carbon, water and energy exchanges in key terrestrial ecosystems in Asia, by promoting multidisciplinary cooperations and integration of scientific researches and practices, and by providing the local communities with sustainable ecosystem services. Currently, KoFlux has seven sites in key terrestrial ecosystems (i.e., five sites in Korea and two sites in the Arctic and Antarctic). KoFlux has systemized a standardized data processing based on scrutiny of the data observed from these ecosystems and synthesized the processed data for constructing database for further uses with open access. Through publications, workshops, and training courses on a regular basis, KoFlux has provided an agora for building networks, exchanging information among flux measurement and modelling experts, and educating scientists in flux measurement and data analysis. Despite such persistent initiatives, the collaborative networking is still limited within the KoFlux community. In order to break the walls between different disciplines and boost up partnership and ownership of the network, KoFlux will be housed in the National Center for Agro-Meteorology (NCAM) at Seoul National University in 2011 and provide several core services of NCAM. Such concerted efforts will facilitate the augmentation of the current monitoring network, the education of the next-generation scientists, and the provision of sustainable ecosystem services to our society.

청계천 복원의 효과가 하천의 형상, 종 조성, 종 다양성 변화의 유연성 및 환경 개선 효과 측면에서 검토되었다. 복원된 청계천은 하천의 종단 및 횡단 형상에서 모두 낮은 자연성을 나타내었다. 종 조성은 부분적으로 자연하천과 유사한 조성을 보였으나 전반적으로 낮은 자연성을 보였다. 종 다양성은 비교적 낮았지만 복원의 역사를 고려할 때 양호한 것으로 평가되었다. 하류와 수변에서는 홍수 후 많은 변화를 가져와 자연으로 회귀할 가능성도 보였지만 상류와 홍수터 이상에서는 변화의 유연성이 낮아 자연으로 회귀하는데 많은 시간이 소요될 것으로 평가되었다. 인공위성 영상 분석 결과, 복원된 청계천은 기온 완화 효과를 나타내었다. 그 밖에 복원된 청계천은 그 주변의 분산된 녹지를 연결하여 그린네트워크를 구축하고자 할 때 핵심적 역할을 할 것으로 기대되어 경관생태적 측면에서의 환경개선효과도 기대되었다.

Knowledge ecosystem means a dynamic knowledge circulation, including knowledge creation, exchange and sharing and utilization. It is also the field of knowledge practice, which creates interactions in knowledge exchange between people and groups. The key premises of knowledge ecosystem, based on the nature of general ecosystems, can be characterized as follows: first, it primarily focuses on social networks between people and organizations participating in the process of knowledge circulation; secondly, knowledge ecosystem thrives on diversity of knowledge; and thirdly, it is significant for selection of valuable knowledge and adoption of appropriate knowledge. This review attempts to make a systematic examination of a wide range of existing studies on knowledge ecosystem. In so doing, it is expected to provide a basis for further inquiry into more critical and complicated issues. Although the scarcity of existing research-at least those in Korea-may limit the implications of findings, this review offers a set of suggestions for future research.

This article examines how and why entrepreneurship differs by region concerning the history of Korea's entrepreneurial ecosystems (EEs). Through a qualitative analysis of 19 interviews, this article compares the history and components of Seoul National University and KAIST (Korea Advanced Institute of Science and Technology) EEs. First, these ecosystems emerged around 1996 and are currently experiencing the second startup boom, with various supporting organizations and actors involved. Second, these ecosystems revealed differences concerning material, social and cultural attributes. Third, differences in the networking of the two ecosystems are due to different regional cultures, which allow individuals to interpret entrepreneurial opportunities. In other words, the maintenance and development of EEs are cultural in essence and display regional variation.

This study was conducted to establish ecotourism as an introduction to sustainability and international cooperation. As a plan to retain the original meaning of ecotourism, the introduction of a program to certify/designateecotourism is being vitalized in many countries around the world. In Korea as well, an agenda to the introduction of an "Ecotourism Designation System,"which aims to ensure the quality of ecotourism at a certain level, was submitted by the Ministry of Environment to the National Assembly in June 2011, and the promotion for a demonstration program is planned this year to introduce the system. Japan has been carrying out the certification systems Good Eco-tour, which certifies the sustainability of ecotourism providers and accommodations since 2006, respectively, and has been securing the sustainability of ecotourism by enactment in 2008, as the world's first law to promote ecotourism. And the second general conference of the first Global Partnership for Sustainable Tourism(GPST) was held in Korea in March 2012, particularly, there was an agreement that the promotion of Asia and the Pacific Area Network for sustainable tourism would center around Korea, and accordingly, it is expected that Korea's status as a core country for ecotourism in the Asia-Pacific Area will increase. While the demand for an approach to natural resources is rapidly increasing, we should be active in providing an institutional strategy such as a designation system to secure the sustainability of ecotourism and seeking a plan for cooperation and network vitalization in the Asia-Pacific Area where similar natural resources and cultures are shared.

세계화를 찬반 선택의 길보다는 오늘날 인류가 처한 하나의 현상으로 받아들여야하지 않을까. 세계화를 신자유주의 경제 이데올로기로만 받아들이기보다는 네트워크, 정보, 문화, 생태와 환경문제 등에서 폭넓게 진행되고 있는 사회적 현상으로 인식해야 할 필요가 있다
