소수력은 국내의 풍부한 부존량을 바탕으로 과거부터 관심을 받아왔으나 대수력에 비해 상대적으로 낮은 경제성이나 하천에 미치는 환경 생태적 영향 등의 이유로 개발이 활성화되지는 못하였다. 최근에는 기후변화협약(1992)이나 교토의정서(1997) 채택 등으로 온실가스 감축문제가 국제적인 이슈가 되면서 신재생에너지 중에서도 탄소배출량이 가장 적은 소수력발전에 대한 관심이 점차 증대되고 있는 상황이다. 그러나 점차 높아지는 환경수요는 대수력에 비해 상대적으로 환경영향이 작은 소수력발전소 건설에도 문제제기를 하기 시작하였으며, 정부의 자금지원에 의존한 '비싼' 전력생산을 회의적 시각으로 바라보는 측면도 존재하고 있다. 본 연구의 목적은 소수력 개발의 장애요인들을 극복하고 우리나라의 풍부한 소수력 부존량을 적극 활용하기 위한 향후 소수력 개발 활성화 방향을 제시하는 것이다. 이를 위해서 소수력발전소의 레크리에이션 기능 활성화, 주변지역의 지원 활성화, 수리권 문제의 해결, 환경친화적인 개발, 신규편익의 발굴 및 계량화, 등을 주요 방향 및 과제로 제시하였다.

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.

This papers aims to focus on the city marketing as the green growth policy strategies using a case study of Gangneung City, Republic of Korea. In the case study it was verified the fields of urban growth including ecology, culture, alternative and recycled energy, green transportation system. The implications of the study were as follows: First, the city government had regenerated the coastal pine forest through removing unlicensed buildings which were squatted down in decades. Secondly, the city government has recognized the value of culture that possessed various types of cultural asserts. Thirdly, it is possible to use and produce the ocean energy with the tidal power plant, wind power plant and green deep water because Gangneung City has the ocean-oriented image and is located the coastal region. Lastly, the city government has been utilizing the LED traffic light using solar heat and is going to apply the green car like an electric car. This paper indicates the importance of the alternatives of the green growth-oriented policy through city marketing using the concept of culture and ecology. The city government will strive after an advanced triple bottom line with the ecological sustainability, cultural diversity and economic effectiveness in the near future.

Germany has carried out its environment friendly energy policy to prevent $CO_2$ emission that affects directly to the global warming phenomenon. Based on this direction, it has performed a sustainable development strategy through the R & D activities in environment and energy technologies. Accordingly, the core elements of German energy and sustainable development policies are renewable energy, ecological energy tax, and emission trading system. In particular, Germany has supported to develop renewable energy resources that prevents from consuming fossil energy resources. At the same time, it has set the ecological energy tax and initiated the emission trading system in order to support the renewable energy policy continuously. This paper analyze whether or not it is possible to generate an economic growth and a sustainable development while using renewable energy resources based on the renewable energy policy that minimize the negative effects on the environment. For that, the paper adopts Germany as a model country. In fact, it is possible to achieve the economic growth and the sustainable development if a nation can substitute increasing energy consumption for the economic growth to renewable energy resources that does not affect to the environment negatively. This model is the German energy policy and sustainable development strategy, and it is the purpose of the paper to prove it logically.

In recent years, various perspectives on the sustainable regeneration based on culture, history, identity, and the ecosystem have arisen in attempt to harmonize the environmental, economic, and social issues of the city. However, these ideas did not consider the importance of urban structure for sustainable regeneration. This research attempts to reveal the fundamental characteristics of sustainable regeneration of Lubbock, Texas in the United States through the analysis of urban structure, city planning and city regeneration planning. Despite the 300% expansion of city area in the 1950s, since the 1970s Lubbock's civic center has decreased in population due to middle class migration into southwestern and western suburbs. In the 1980s, a redevelopment organization was established, and a private sector-centered regeneration plan was implemented. In this study, a new approach for urban regeneration was introduced, resulting in strategies focusing on the linkage of urban regeneration into the characteristics of the entire city.

This research is aimed at identifying the perception associated with urban regeneration and predicting policy implications of future directions by analyzing the trend of urban regeneration depicted in the mass media by utilizing SNA (Semantic-Network Analysis) techniques. As the number of articles has increased, it is noted through analysis that the interrelationships between social phenomena and issues have combined to form the meaning of urban regeneration. Overall, 'urban' and 'regeneration' keywords also appeared at different periods, with 'urban' closely related to 'regeneration' starting in 1970 when urbanization was becoming more prevalent. It was analyzed that the frequency of 'urban' appeared more frequently in the early 1990s, while the frequency of 'rural' decreased sharply. Until the 1990s, the slums and the recession that appeared as side effects of urban problem-solving policies were mostly concentrated in cities. Policy discussions were conducted with the goal of improving the physical environment of cities rather than concentrating on the surrounding rural areas. The distributions of the keywords 'development' and 'regeneration' have increased quantitatively since the 1970s, and urban polarization has exploded due to the development of the external growth of cities, mirroring the trend of accelerated environmental threats. In particular, the keywords for 'regeneration' emerged mainly related to environmental problems, which led to the need for urban regeneration, and environmentally and ecologically friendly development. The emergence of "urban," "regeneration" and "environment" as keywords having to do with urban regeneration grew in the 1990s. This suggests that urban regeneration is now linked to "environment", as that has become a social issue.
