  • This study aims to understand the thematic trends globally developed in the 'Green Urbanism' related research. Research methodology is based on systemic review of international literature published for the past 20 years period between 2000 and 2020. The specific methods applied include not only literature search by citation, co-authorship, and co-occurrence but social network analysis in order to find correlations among the publication. The correlations are visualized and analysed using VOSviewer and Ucinet software. The analysis indicates that total of 51 studies were carried out by 89 authors from 54 institutions across 21 countries during the period. The majority of the research was done by a country-specific study and only a few research were collaborative studies with other countries. The most common theme that occurred in the early years was 'sustainability and the theme evolved toward specific ones such as 'built environment', 'infrastructure', and 'health'. Having considered that climate change has become a global challenge, green urbanism is expected to be a future direction to pursue environmentally sustainable urban spaces. This study also implies that governance, policy support, and intervention are crucial factors in developing sustainable urban spaces.

  • The red swamp crawfish (Procambarus clarkii) is native to northeastern Mexico and south-central United States. But the species has been introduced to other parts of the world, and cause ecological problems including habitat destruction and competition with indigenous species. In this study, we identified the distribution of P. clarkii in the freshwater system in Korea. P. clarkii were collected in the field sampling and it is assumed that they have settled in major domestic water systems of Korea including six points in the Yeongsangang River, five points in the Mangyeonggang River, two points in the Seomjingang River, and one point in the Geumgang River. In particular, more than 20 individuals were found in Seobongri, Wanjugun and Mosanri, Hampyeonggun, which are believed to form a relatively large population. Considering high mobility and environmental adaptability of the species, the possibility of their dispersal to other water systems is very high. Therefore, continuous monitoring and assessment of their distribution and potential spread are required and effective management to remove them policy is needed to prevent damage in the Korean ecosystem.

  • Although competitions for large parks are increasing rapidly across the world, theoretical research and critiques of these competitions are as yet insufficient. The 'International Design Competition for Central Open Space in Multi-functional Administrative City, Korea', a representative competition for large park design, can be a significant resource for examining the contemporary design strategies that go into the design of a large park. In this study, the authors make a framework for analysis by looking at the competition's design guidelines and literatures on 'large parks', and by then analyzing the ten finalists. Four questions that were derived from the framework were: 'what are the approaches to large parks?', 'what is the process of design?', 'what is the sustainability of the park?', and 'what are the relations between city and park?' The results of the study are as follows. First, the design concepts for large parks are primarily site-specific. It is particularly important in ensuring the identity of the large park. Second, it is difficult to find design proposals which satisfy the four main questions sufficiently, and works submitted tend to be visual-oriented, form-oriented, and results-centered. Third, the notion of 'sustainability' in large parks is a comprehensive one which includes various aspects such as ecology, finance, programming, and community. However, the notion remains ambiguous, and plans for operation and management are not concretely proposed. Finally, design proposals for large parks accompany positive relations with the city. Especially, 'productive parks' and 'city self-sufficiency' are very important demands in regards to large parks.

  • World population has increased rapidly following the industrial revolution, reaching 7 billion in 2012. Several forecasts estimate that this number will rise to about 8 billion in 2025. Improvements of living standards in developing nations have also raised resource and energy demands worldwide. In consequences, human beings have faced many global and urgent problems, such as global warming, water and food shortages, resource and energy crises, and so on. Many ocean utilization technologies for avoiding or reducing such big problems have been developed, for examples $CO_2$ ocean sequestration, seawater desalination, artificial upwelling, deepwater mining, and ocean energies. It is important, however, to assess such technologies from the viewpoints of sustainability and public acceptancy, since the aims of those technologies are to develop sustainable social systems rather than conventional ones based on fossil resources. Inclusive Marine Pressure Assessment and Classification Technology Research Committee (generally called IMPACT Research Committee) of Japan Society of Naval Architects and Ocean Engineers, has proposed Inclusive Impact Index "Triple I" as an indicator, which can predict both environmental sustainability and economical feasibility, in order to assess the ocean utilization technologies from the viewpoints of sustainability and public acceptancy. This index was considered by combining Ecological Footprint and Environmental Risk Assessment. The Ecological Footprint and the Environmental Risk Assessment are introduced in the first part of this paper. Then the concept and the structure of the Triple I are explained in the second part of this paper. Finally, the economy-ecology conversion factor in Triple I accounting is considered.

  • This study was investigated on the basis of the role of housing cooperatives in sustainable regional business networks(SLEN) in regeneration of residential aged area where the urban poor live. For the analysis, input elements of human capital, social capital, financial capital and ecological capital were examine. For the process, the organization's structure, sustainable business and social networks, and for the result, the stability and community characteristics of the living and the payment possibility of housing construction cost were examined. Through this study, what kinds of issues can be from the housing coop's project in terms of sustainability, and what is the most important factor in order to overcome former mentioned issues were intended to find. For analysis literatures were reviewed and the in-depth interviews and survey were conducted with site visits. The result of this study finds that housing coop have community characteristics through active participation of residents during the regeneration process but the land, as financial and ecological capitals, and housing construction funds were poor. This was investigated that it makes groundless the sustainability of the project and the possibility of the payment. In order to overcome, land concession, inexpensive lental and active funning for housing construction to housing coop is required because housing coop is aiming to supply of social housing for low-income and vulnerable groups.

  • For sustainable use of the resources of uninhabited islands of Korea, their ecological economic potential needs to be fully integrated into their management policy and the carrying capacity of the islands should be evaluated before using or developing them. The emergy methodology was used to evaluate the ecological economic value and carrying capacity of Sungap-do which is an uninhabited island in Incheon, Korea. The system boundary for the emergy evaluation of the island included the sea area within 1km from the high tide level, following the management boundary for the uninhabited islands of Korea stipulated in the Law on the Conservation and Management of Uninhabited Islands. The total renewable emergy input to Sungap-do was $1.04{\times}10^{20}$ sej/yr from tidal energy. The annual ecological economic contribution of the island was evaluated high at 29.9 billion Em₩/yr. If Sungap-do were developed to the national average, its carrying capacity was 6,586 persons at the current living standard of Korea. The carrying capacity of Sungap-do for the long-term sustainability scenario was 2,337 persons at the same living standard as in the developed scenario. When only emergy contribution of the land area was considered, the carrying capacity of Sungap-do sharply decreased to 14 persons for the developed scenario and 5 persons for the long-term sustainability scenario. The carrying capacity of the uninhabited islands of Korea including Sungap-do, thus, needs to be considered from the initial stage of utilization or development projects to sustain the ecosystem benefits and their sustainable uses.

  • 자연은 인간이 만들어낸 기술적 해결책들보다 현저히 적은 양의 에너지를 소비하며, 적은 물질로 다양한 구조를 창출해 내는 고효율 최적화 시스템이며, 스스로 정화작용과 선순환을 유지하는 환경 친화적 시스템이다. 이러한 자연에서 영감을 얻어 활용하고 응용하는 기술은 최근 나노-바이오기술의 급속한 발전과 더불어 새롭게 각광받는 융합기술 분야로 부각되고 있다. 나노스케일의 생체물질을 관찰하고 특성을 평가할 수 있는 고성능의 장비가 개발되고, 생체 물질을 분자 단위로 조합하고 합성하는 등의 첨단기술이 발전됨에 따라 자연모사기술도 새로운 전기를 마련하고 있다. 자연 생명체/생태계가 지닌 혁신적인 해결 가능성(Innovation Potentials)을 구현하기 위해서는 자연모사기술 분야에 좀 더 체계적이고 지속적인 관심과 지원을 기울여야 할 것이며, 이를 바탕으로 인류가 당면한 에너지 자원 기후변화 환경 문제 등의 글로벌 이슈를 극복하고 선순환의 개념의 자연모사 에코 기술과 지속가능한 혁신 기술 달성이 가능할 것으로 기대된다.

  • 국내 창업 생태계는 최근 몇 년 사이에 양적으로 급속히 팽창하였다. 정부 또한 가장 시급한 문제로 일자리 창출을 꼽고 이에 대한 해결방안 중 하나로 창업지원을 대폭적으로 확대하며 중소기업에 대한 지원확대를 제시하고 있다. 이러한 배경 하에 창업의 양적 성장은 위에서 설명한 바와 같이 가시적으로 나타나고 있다. 하지만 창업기업의 양적확대라는 긍정적인 측면에도 불구하고 창업기업의 낮은 생존율은 개선의 시급함을 나타내고 있다. 국내 창업기업 10곳 중 7곳 이상이 창업 5년 이내에 폐업을 하고 있는 상황이다. 이와 같은 이유로 2015년부터 중소벤처기업부는 창업기업의 데스밸리(Death Valley) 극복 및 성과창출을 위해 창업 후 3년 이상 7년 이내 기업을 대상으로 자금 및 서비스를 지원하는 등 창업기업이 어려움을 극복하고 사업 지속 가능성을 높이기 위하여 다양한 노력을 하고 있다. 본 연구의 목적 역시 창업자가 사업을 진행하면서 겪는 어려움을 극복하는 요인과 사업지속의지가 어떠한 상관관계를 가지고 있는가를 조사하고 분석하는데 있다. 본 연구에서는 사업 어려움 극복영향 요인(창업자 역량, 지원시스템)이 사업지속의지에 미치는 영향에 관한 연구를 경영성과의 매개 역할과 사회적 지지의 조절 역할을 하는지를 중심으로 진행하였다. 따라서 본 연구에서는 창업자 역량과 지원시스템이 경영성과를 증진하고, 증진된 경영성과가 사업지속의지에 영향을 미칠 것이라는 인과적 경로를 검증하고자 한다. 사회적 지지를 조절변수로 설정하여 본 연구를 진행하였다.

  • Ecotourism is an alternative tourism which can be defined as responsible tourism in natural areas. This study deals with changing the tourists' environmental attitudes of ecotourism activities based on the elaboration likelihood model(ELM). The surveys were conducted based on the same participants to clearly measure the differences of environmental attitudes between pre and post-participation ecotourism activities. A total of 183 samples were collected in Upo Wetlands. The results showed that there were significant differences in the tourists' environmental attitudes between pre and post-participation ecotourism activities. This indicates that ecotourism participants delicately reinforce their eco-friendly attitudes through various ecotourism experiences and educational programs. The most significant finding is that anti-environmental behavior can be relieved with eco-friendliness through participation in ecotourism.
