Restoration ecology is undergoing rapid growth as academic field over the last 15 years. The specification of goals for restoration projects is frequently described as the most important component of a project. The endeavor for universal development of goals for ecological restoration continues to generate many discussion and controversy. I discuss the importance of restoration goals and diverse roots of restoration ecology, and show how the complex lineages within restoration ecology. I review the three major theme that currently are used to develop the restoration goals : restoration of species, restoration of whole ecosystem or landscapes, and the restoration of ecosystem services. Restoration ecology, landscape ecology and conservation biology share goals to conserve biodiversity, but differ in focus of approach. I review the differences among three fields. Conservation biology has been more zoological, more descriptive, and theoretical, and more emphasized the population and genetic research. However, restoration ecology has been more plant ecological, more experimental, and emphasized the community and plant succession. Landscape ecology has emphasized the interaction of ecosystem and dispersal among populations. I suggest the integration of restoration ecology, landscape ecology and conservation biology. For example, conservation biology will contribute to the preservation of original habitats by population study, restoration ecology will contribute to regenerate damaged ecosystem and ex situ preservation, and landscape ecology will contribute to restoration of population and landscape.

Ecological modeling faces some unique problems in dealing with complex environment-organism relationships, making it one of the toughest domains that might be encountered by a modeler. Newer technologies and ecosystem modeling paradigms have recently been proposed, all as part of a broader effort to reduce the uncertainty in models arising from qualitative and quantitative imperfections in the ecological data. In this paper, evolutionary computation modeling approaches are introduced and proposed as useful modeling tools for ecosystems. The results of our case study support the applicability of an algal predictive model constructed via genetic programming. In conclusion, we propose that evolutionary computation may constitute a powerful tool for the modeling of highly complex objects, such as river ecosystems.

생태계서비스 계정은 생태계 공급 기능과 수요, 그리고 그 사이에서 발생하는 실제 서비스 흐름을 측정해야 한다. 흐름을 측정하기 위해서는 공급과 수요 관계를 정의해야 하며, 복잡한 연결 관계를 객관화 할 수 있는 방법론이 필요하다. 국내에서는 생태계서비스에 대한 연구가 다양하게 진행되어 왔으나, 생태계서비스 계정화에 관한 연구는 부족하다. 본 연구의 목적은 환경경제통합계정(SEEA)의 실험적 생태계계정(EEA)에서 연구된 EU 방법론을 적용하여 홍수조절 생태계서비스를 평가하고 이를 토대로 생태계 계정 도입 방안을 모색하는데 있다. 연구수행을 위해 생태계의 유출량 보유 잠재력, 홍수조절에 대한 사회·경제적 수요, 그리고 그 사이의 관계로부터 형성되는 실제 서비스 혜택 흐름을 공간 기반으로 모델링하고 정량화하였다. 홍수조절 생태계서비스 실제 흐름을 산정한 결과, 국내 전체 서비스량은 165,595ha로 산출되었으며 많은 부분이 농경지에 집중되고 있음을 확인할 수 있었다. 향후 국내 홍수조절 서비스 계정 정밀화 도입을 위해서는 토지피복도와 같은 핵심 공간자료가 지속해서 구축 관리되어야 하며, 국가, 지역, 유역 등 다양한 공간 범위에서 적용 가능한 입력자료 및 방법론에 대한 연구가 필요할 것으로 보인다.

The Fourth Industrial Revolution is currently leading humanity into a super-connected, super-intelligent, and super-converged society through key technologies such as artificial intelligence, the Internet of Things (IoT), and big data. Blockchain technology has the potential to lead social innovation that will improve the mutual harmony and understanding of the complex structures of human society as well as various phenomena (e.g., antagonism, confrontation, and ideological conflict). With such progress in social innovation, blockchain technology will result in a fairer and more transparent human society. In addition, blockchain technology is emerging as a core infrastructure technology, and its growth and expansion are expected to bring about revolutionary improvements to nearly all fields of development and research. In this paper, we briefly outline the main features of blockchain technology. Through a further analysis of its ecosystem, we intend to offer suggestions for a more robust and efficient development of blockchain-related industries.

본 연구에서는 생태계서비스 중 수질조절 서비스 가치 평가를 수행하기 위해 생태계서비스 수질조절 서비스의 물리량을 정량적으로 평가하였고 이를 이용하여 경제적 가치를 평가하는 방안을 마련하였다. 과거에 비해 수질이 개선되고, 어류 등 수생생물의 종과 수가 늘었더라도, 그 요인은 생태계의 수질조절 서비스와 수질개선를 위한 환경기초시설의 확충, 수질환경규제 등 복합적인 요인에 기인된다. 그 중 생태계 조절서비스 가치에 대해 정량적으로 산정할 수 있는 방법을 모색하는 것을 연구의 목적으로 설정하였다. 본 연구에서 생태계의 수질조절 서비스를 정량적 가치를 규명하기 위해 수질오염총량을 활용하는 방법에 대해 제안하였다. 이와 함께 생태계의 수질조절 서비스의 산정된 물리적 수질조절량에 처리단가를 곱함으로써 경제적 가치 평가 방안을 제시하였다. 마지막으로 개발된 평가기법을 이용하여 낙동강 수계에 BOD, T-P 항목에 대해서 생태계 수질가치를 평가하였다.

In the last five decades, there has been a consistent decline in the total catch of fisheries in the Korean jurisdiction since the peak in 1986. The decline in catch slowed and slightly rebounded in the 2000s, but changed back to a decline in the 2010s. As indicators that can identify changes in the marine ecosystem, trophic level (TL), biodiversity index (H'), and the ratio between pelagic fish and demersal fish (P/D) were analyzed by each local marine ecosystem. There were some different changes in each local marine ecosystem, but the mean TL and H' decreased and P/D increased in general in Korean waters. Demersal fish, which were dominant in the 1970s and 1980s, declined, and small pelagic fish and cephalopods have dominantly changed since the 1990s. However, these changes are not simple, and they are fluctuating in complex ways relating to each marine ecosystem and the timing. It is believed that changes in marine ecosystems in Korean waters are likely caused by a combination of fisheries and climate change. The ecosystem indicators reflected a change in the total catch, a sharp drop in catch of demersal fish, and increasing catch of pelagic fish since the mid-1980s.

Given the substantial industrial and economic contributions of university start-ups, a growing number of studies have adopted the ecosystem perspectives to systematically explain creating start-ups in universities. Despite the huge theoretical potential, few studies have analyzed the complex, complimentary interactions of the core components in the university entrepreneurship ecosystems (UEEs). Addressing the limitation, this research not only discusses the role of the core ecosystem components, such as patents, entrepreneurship education, and student entrepreneurship clubs, but also analyzes their discrete and complimentary effects on the productivity of UEEs. Based on a national survey of universities, this study shows that all the core components have a positive effect on the ecosystem productivity. More importantly, this study investigated the complimentary relationships among components and tested the moderation effects of both the entrepreneurship education and the student clubs on the relationship between the patents and the productivity of UEEs. The analysis results show that the student clubs intensify the patents' positive effect on the productivity of UEEs. The research results could provide the crucial policy insights for the successful design of UEEs.

Biodiversity, referring to the variety and abundance of species, their genetic composition, and the communities, ecosystem, and landscapes, is essential to maintain healthy and productive forests, and to provide useful hedge against the future uncertainties in conditions of the environment and natural resources. To realize the long-term sustainability for forest production of goods and services is dependent upon maintaining and enhancing the biodiversity in the forest ecosystem. Because we can not always recognized which portion of biodiversity is essential to maintain the stability and sustainability of the natural system, conserving biodiversity is even unconditionally important. Even though the activities of forest resource management may have a variety of negative impacts on biodiversity by modification of the natural ecosystem into economically effective artificial ecosystem, forest professionals have been developing intelligent scheme to coexist management and conservation. However, conservation of biodiversity must be a complex problem encircled by ecological, economical, and social considerations. There seems to be no such a simple and easy solution. Strategies for ecologically deliberated forest resource management, which could play an important role to conserve biodiversity, were discussed.

2006년 광릉 활엽수림지역에서 관측된 자료를 활용하여 수정된 토양-식생-대기 모델을 보정하고 연간 순생태 교환량의 계절변동성에 대한 모델의 모의 능력을 평가하고 탄소교환을 조절하는 주요 인자에 대하여 조사하였다. 수정된 토양-식생-대기 모델(mSPA model)을 1000 LST부터 1400 LST까지 관측된 낮 시간의 평균 순 생태 교환량(Net ecosystem exchange)을 모의하도록 보정한 후 총 일차 생산량(Gross primary productivity)을 계산하는데 사용하였고 생태 호흡량(Ecosystem respiration)은 관측지에서 개발된 경험식을 사용하여 추정하였다. 모델 결과는 여름철에 낮 시간의 평균 기공 전도도는 일사량과 매우 높은 상관성이 있음을 나타내었고 수증기 포차는 기공전도도의 변화에 큰 영향을 미치지는 않음을 보였다. 모델은 성장기간에 두 개의 극대값을 갖는 관측된 순 생태교환량의 계절 변동성을 모의하였다. 모델에서 계산된 연간 총 생산량과 생태호흡량, 그리고 순 생태 교환량은 각각 $964gC\;m^{-2}\;yr^{-1}$, $733gC\;m^{-2}\;yr^{-1}$ 그리고 $-231gCm\;^{-2}\;yr^{-1}$이었다. 관측값에 기반하여 산정된 연구결과와 비교할 때 모델 추정값이 약 $140gC\;m^{-2}\;yr^{-1}$ 더 많은 탄소 흡수를 보였다. 복잡한 지형에서 연간 생태 교환량 추정의 불확실성에 대하여 논의하였다.
