Finding promising wind farm sites in islands of Korea is performed in this study. Total ten islands that have been measuring wind speed and direction using automatic weather stations for at least ten years were subjects of this study. Conditions for finding suitable wind farm sites including wind resource and various exclusion factors were applied and two islands that were found not to be suitable for wind farms were excluded. Micositing of a single wind turbine for the remaining eight islands was performed to estimate the annual energy production and the capacity factor.. Based on the simulation results, the wind farm sites selected within the eight islands were found to be suitable for wind power. The capacity factors were varied between 22.3% and 33.0% for a 100 kW wind turbine having a hub height of 30 m.

연료전지 발전시스템은 발전효율이 높고, 공해물질이 없는 등 많은 장점을 갖는 에너지생산 방 식에 따라 장래의 이용이 크게 기대되고 있다. 현재 연구개발에 많은 성과를 보이고 있는 미국. 일본에서는 인산형 연료전지의 상업화를 위해 수 MW급의 발전시스템의 신뢰성 실험을 진행 중에 있으며 용융탄산염형 연료전지, 고체산화물형 연료전지의 기초연구를 거의 완성한 단계에 있다. 국내에서도 연료전지발전은 화력발전의 한계, 발전연료의 다원화에 따른 천연가스의 수 입이용이 대폭 확대될 전망임에 따라 이용의 필요성이 많이 대두되고 있다. 특히 많은 섬과 산간지방 등 고립분산지역을 갖고 있는 국내 여건으로 볼 때, 송전. 배전시설이 필요 없는 온사이 트형 연료전지 발전설비가 설치될 경우 많은 이점을 가져올 수 있기 때문에 동 분야의 연구개 발이 필요한 상황이다. 전력은 국가의 핵심에너지로서 전력생산기술의 자립은 매우 중요하다. 특히 우리나라도 선진화되면서 새로운 첨단기술의 도입에 의한 에너지생산기술의 확보가 선진 국들의 기술보호정책에 의해 장애를 받고 있다. 연료전지기술의 경우도 일본이 동 분야를 국 책과제로 지정한 뒤 각 기업이 연구개발에 나서고 있는데, 이미 1980년대 초에 미국과 기술제휴 를 하면서 아시아지역 전체에 대한 전매권을 확보한 상태이며, 다른 타국과의 기술제휴 및 기 술이전을 거부한 채 실용화를 위한 경제성 확보의 시기를 기다리고 있다. 이와 같은 이유로 극복하기 위해 집중적인 투자를 확대하여 독자적인 기술을 확보해야한다.

Although the Dreamland site was the only flat amusement park in the northern part of Seoul, the site lost its function as a regional park due to aging and, therefore, was no longer in use. The site is surrounded by currently existing high dense low-story housing blocks and proposed new towns. A renovation plan for Dreamland was raised by the City of Seoul to enhance the quality of the urban environment in the northern part of Seoul. This study articulates the design concepts and strategies of the prizewinning work of the International Design Competition for Gangbuk Large Park. The three key points can be summarized as follows: First, this design proposal tried to find a new possibility for a large mountain park in an urban areas. These days, mountain parks are used limitedly as ordinary living spaces for activities such as a walking, hiking, and physical training. New strategies were sought to reconstruct the sentiment with which our ancestors enjoyed the mountains. Second, this proposal tried to make Dreamland a socially self-sufficient park. We designed a park which generates self-energy and which communicates with the city, not a park which only exists as a green island in a city. Lastly, rain fed paddy fields, a typical Korean vernacular landscape, was a tangible space which represented people's life-styles harmonizing with the nature. Rain fed paddy fields is a design motif which puts the three surrounding mountains together with the site. It is expected that the new design will works as a noted place.
