This research developed an approach to identify ecologically important areas at local scales and explained how the results of this approach could contribute to extend the protected areas in the Republic of Korea (ROK). While most developed countries have considered various biotic and abiotic factors, ecological processes, migration routes, habitat connectivity, ecosystem services, and etc. to determine the protected areas, ROK has considered a few factors focusing on biodiversity, landscape, and the habitats of endangered organisms. However, for sustainable management of our nature, we need comprehensive understanding of various ecosystem factors and interactions among them at local scales in designating protected areas. Forthis, we developed a conceptual model based on the ecological engineering approach and then explained how the results of this approach could contribute to extend the protected areas. In particular, we considered future land-use and climate change in determining the priority areas for novel protected areas. Our research suggested an effective methodology 1) to include various ecosystem factors and 2) to consider future environmental changes as well as current environmental conditions in finding the ecologically important areas and prioritizing these areas. However, our approach has limitations on the real-world applications due to the lack of fundamental information and data on our ecosystems. To improve the effectiveness of our approach in the real-world applications, we need various long-term ecological research results, environmental and ecological monitoring data, and both current and future spatial environmental data.

This paper proposes policies for developing ICT ecosystems so that Korean ICT companies can have a competitive power under the changing ICT industry environment. It analyzes the changes of user characteristics, their consumption trends and ICT industry environment. It also examines problems of domestic ICT industry and overseas ICT policies. In addition, it investigates the ICT ecosystem strategies of Google and Apple based on the theory of business ecosystem. This study suggests government policies for establishing a smart ecosystem, incubating a strategic ecosystem, and maintaining a sustainable ecosystem. The findings of this study provide additional insights and guidelines for policy makers to develop effective ICT ecosystems.

다양한 센서와 네트워크의 발달로 인하여 여러 분야의 사물인터넷 서비스들이 보급되기 시작하였다. 국내 사물인터넷 서비스의 인프라 수준은 높지만 사물인터넷의 생태계의 부족으로 인하여 사물인터넷 서비스의 경쟁력이 약하다. 이는 사물인터넷 발전에 부정적이 영향을 가져올 수 있으므로 사물인터넷의 생태계의 구성에 관한 논의가 필요하다. 본 논문에서는 사물인터넷 생태계를 비즈니스 관점과 시장 중심의 관점으로 분석하고, 세부적으로 생태계를 구성하는 4가지 요소에 대해 분석한다. 또한 국내 사물인터넷의 생태계의 부족한 점에 관하여 논의를 한다. 본 논문은 사물인터넷 생태계의 분석을 통하여 국내 사물인터넷의 생태계의 도움을 주는 역할을 할 것이다.

본 논문은 EU의 TEPSIE 연구에서 정의한 사회혁신 생태계를 분석틀로 활용하여 한국 사회혁신 생태계의 현황을 살펴보고 발전방안을 제시하고 있다. TEPSIE가 정의한 사회혁신 생태계는 전사회적인 차원에서 '사회혁신'의 요소들을 담아냄으로써, 사회적 경제와 연관하여 사회적 기업을 논의하는 과정에서 다소 협소할 수 있었던 시각을 확장하여 구조적 환경과, 자원, 파트너쉽 등을 포괄하는 분석틀을 제공한다. 본 논문에서는 사회혁신기업을 둘러싼 구조적 조건, 수요와 공급 차원에서의 관련 요소들, 그리고 중간지원조직을 중심으로 핵심적인 내용을 분석적으로 담아내고, 이를 바탕으로 사회혁신 생태계의 발전 방안을 제시하였다.

As the complexity of business environment increases rapidly the use advanced information technology start to affect not only the business processes of individual companies but also the fundamental nature of business and industrial ecosystem. The changes observed at the level of business and industrial ecosystem encompasses a broad range of transformation. This unit of analysis is not sufficiently dealt with by existing information systems research. This research attempted to analyze the changes in business ecosystem caused by digital transformation using a relatively new approach called ecosystem mapping. We developed and suggested an ecosystem mapping methodology step by step and applied the methodology to film industry. The film industry is chosen because it is an industry very sensitive to the changes in technology and has gone through massive transformation during the last three decade by way of using modem information technology.

IPCC 5차 보고서에 따르면 지구 평균 기온상승은 저위도 보다 극지방에서 더욱 뚜렷하게 나타나며 이러한 기후변화는 극지 생태계의 변화를 초래한다. 이러한 기후변화에 따른 극지 생태계의 변화를 분석 및 예측하기 위하여 지면-생태계 모형을 구축하고 극지방 생태계, 수문 및 탄소 순환 등을 모의하는 연구들이 많이 진행되고 있다. 최근 극지 지역에서는 기후변화로 인하여 화재 발생 빈도가 증가하고 있으며, 이로 인하여 극지 생태계뿐 아니라 물순환에 많은 영향을 미치고 있다. 하지만 지면-생태계 모형안의 화재 시뮬레이션은 화재의 원인 파악의 부족, 입력자료의 부족, 화재 역학 이해의 부족 등의 한계가 존재한다. 본 연구에서는 2001~2012년 동안 위성에서 관측된 화재면적 자료인 Global Fire Emissions Database (GFED) v4 자료와 지면-생태계 모형인 NCAR Community Land Model (CLM)-biogeochemistry (BGC) 와의 실시간 융합을 통하여 기존 화재 시뮬레이션의 한계점을 보완하고자 하였다. 기존 CLM-BGC 모형을 통한 증발산량, 화재 자료-모형의 융합을 통한 증발산량 결과와 Moderate Resolution Imaging Spectroradiometer (MODIS) 증발산량 자료와의 비교를 통하여 증발산량 모의에 화재의 중요성을 분석하고자 한다. 또한, 유출량 뿐만 아니라 토양수분의 변화를 시·공간적 변화를 분석함으로써 화재가 극지방 물순환에 미치는 영향을 나타내었다. 또한, 본 연구를 통하여 미래 기후변화에 따른 극지방의 생태계 및 물순환을 모의하기 위하여 화재 시스템 구축의 중요성을 제시하였다.

16S rRNA를 분석한 연구들은 자연 생태계에서 추출한 핵산을 이용하여 16rRNA 유전자의 염기서열을 분석하거나 특정 DNA probe를 이용한 hybridization 실험이 주류를 이루어 왔다. 특히 PCR 기법이 개발됨에 따라 적은 양의 시료를 대량으로 손쉽게 증폭시킬 수 있어 다양한 분야에 응용되고 있다. 세균 군집의 구조를 이해하는데 있어서 PCR 방법의 적용 대상은 주로 16S rRNA 유전자의 염기서열 해독분야이며 해양 생태계를 대상으로 많은 연구 결과가 보고되었다(11,13,21,26). 한편 자연 생태계의 개별적 미생물 분류룬들을 검출하기 위한 특정 oligonucleotide probe의 개발방법들은 미생물 군집의 유전적 다양성에 대한 정보 파악 이외에 배양이 어려운 혐기성 세균과 같은 특정 세균들의 동정에도 이용되고 있다(3,24,55). 본고에서는 세균 군집의 구조와 다양성을 연구하는데 적용 가능한 rRNA 분석방법들을 수계 생태계를 중심으로 살펴보고자 한다.

The concept of ecosystem services is important for the effective management of regional ecological resources. Multiple ecosystem services provided by regional ecosystems are represented as ecosystem service bundles, which define the co-occurrent ecosystem services in a specific region. Bundles provide useful information to identify regional characteristics of ecosystem services and categorize sub-regions with similar patterns of ecosystem service provision. We assessed eleven ecosystem services using modeling approaches and statistical data and produced bundles of cities in Gyeonggi-do.We also conducted principal component analysis and cluster analysis to categorize these cities according to the characteristics of ecosystem services. The results indicated that the cities in Gyeonggi-do were categorized into three groups depending on the types of provision,regulation, and cultural services, and were designated as urbanized, urban-forest, agriculture, or forest cities. These groups were influenced by land use patterns reflecting regional social-environmental features. The results provide useful information for identifying regional ecosystem services and facilitate decision-making in regional ecosystem service management.

The development of IT increases the importance of understanding of IT-driven ecosystems. Platform business is the representative business model in the era of innovative IT-based businesses. However, it lacks the review research that entails ecosystem perspectives from traditional disciplines in which the perspective of ecosystem had been applied. Further most of platform research have focused on the comparison between ecosystems as a whole rather than exploration on complementors in the ecosystem who are selected and survive and, in turn, contributed to maintain the ecosystem to compete with other ecosystems. The current study listed highly cited papers from economics, sociological ecology, socio-technical ecology, organization studies, and marketing research which have cumulated research on ecosystems. And the three most critical features that determine the success of complementors, which are competition, relationality, and adaptability. Present study showed how the features were explained by each perspective from the different disciplines.

Business ecosystem is becoming more inclined towards platform ecosystem, which attracts multi-side participants based on digital technology. The burgeoning interest in digital ecosystem leads to the rapid rise of research. In this paper, we suggest a research agenda, focusing on the benefits of complementors in platform ecosystem. First, we outline the extant papers on benefits from platform to participants from economic perspective, strategic management perspective, technology management perspective, and economic sociological perspective to provide comprehensive understanding about platform ecosystem. Second, we suggest systemic framework to provide integrative insights on the the topic of benefit from platform to complementors- (1) open innovation view, (2) economic performance view, and (3) sociological view. Specifically, we focus on empirical studies that investigate the relationship between the benefits from platform and spillover effects on complementors based on various dataset. In addition, by reviewing the past empirical research, we suggest future research agenda and implications for policy in platform ecosystem.
