As the industrial complexes that led the national economic growth of Korea become older, it is necessary to prepare countermeasures to improve the competitiveness of these industrial complexes. The purpose of this study is to analyze the determinants of the competitiveness of old industrial complexes in Korea. It was found that the characteristics of the industrial structures, new companies, the working and production environments, and the regions in which these complexes exist all affect their competitiveness, but the effects differ according to the size of the complex. In particular, for large-scale complexes, the central government should play a role in their restructuring to improve their competitiveness. On the other hand, local governments' management of new companies is more important for small-scale old industrial complexes. These results provide implications with regard to the effective management of old industrial complexes.

The final site of offshore wind power plant should be decided by comprehensive examination of various conditions such as wind resource, sea depth, geology, grid connection, social circumstance and environmental issue. Wind condition is typically regarded as the most important factor because wind energy increases in proportion to wind velocity and it directly relates to the amount of power output, efficiency of power plant and profitability. Advanced countries in the offshore wind power sector such as Denmark, UK and Germany, they are analyzing wind resource accurately by installing the meteorological mast in the ocean in order to get the optimal type of wind turbine and maximum generation efficiency. Also, it is made much of designing offshore power plant on the basis of actual measurement by met-mast and those wind farms have a chance to get the loan with reduced interest rate in project financing. In Korea, the HEMOSU-1 is installed in the ocean around Wido island to analyze wind resource of test bed of 100MW offshore wind power on october last year. This paper deals with the design and construction procedure of the first met-mast in Korea and also shows the site characteristics of test bed. Therefore, this paper will give useful information to local governments and private business sector who are trying to construct offshore wind farm and it can also be a good reference for the following projects of meteorological mast in near future.

By analyzing the use of outdoor space in apartment complex and finding empirical proof which is concrete and systemic, this study focuses on the relationship between residents' daily lives and physical space. This study tries to find out the types and characteristics of outdoor space which causes the occurrence of residents' use in High-Rise apartment housing Estates, and analyzes the residents' usage pattern of outdoor space in eight different apartment complexes which were builted since 2004. After analyzing the usage pattern of outdoor space, the usage of playground was ranked highest and playing, talking, exercising, resting was in order. Especially it was found that the usage inside semi-public space where passing is abundant increases.

The purpose of this thesis is to derive the demand expediting measures of the garden-housing site suitable to the Pusan metropolitan region through understanding the characteristics of the preference based on the investigation of the demand. From the empirical study of the thesis, we developed the following demand expediting strategies of the garden-housing site. First, the development concept should be focused on the market demand and community building. Second, the garden-housing site has to be developed near the existing urban areas and the site must have the convenient facilities and infrastructures. Third, community building concept should be applied in the site design.

Developing the offshore wind farm is essential to meet the national target of the renewable energy and to achieve the green growth in Korea. In this context, KEPRI is now carrying the feasibility study for introducing the offshore wind fam in Korea. Accordingly, it is required to formulate an appropriate strategy, this paper mainly discuss, for this goal. First of all, several preliminary sites for the offshore wind farm are selected based on the evaluation criteria presented herein. In addition, the domestic sub-technological level of key technology sectors associated with the offshore wind power is analyzed. It includes the industries related to wind turbine, grid integration, structural design and construction. Integrating these results, we propose a strategy in order to successfully develop the first offshore wind farm more than 100-MW class in the south-western sea area of Korea.

에디슨이 전기를 발명한 후 지난 100년간 전력산업은 증가하는 전력수요에 대응하기 위해 공급측면에서 발전소 및 송배전 설비 건설을 통해 전력공급 문제를 해결하여 왔다. 이 과정에서 화석연료 사용으로 인한 지구환경오염, 화석연료 고갈에 따른 에너지 가격 급등등으로 신규 대체자원의 개발과 수요측면에서 대응방안 마련이 절실한 상황에 이르렀다. 이러한 문제를 해결하고자 하는 전력산업의 패러다임이 스마트그리드이며, 본 논문에서는 스마트그리드 핵심자원인 수요측자원에 대해 스마트그리드 제주실증단지 전력시장에서의 수요자원 운영방안에 대한 체계를 제시하고자 한다.

포항공과대학교의 포항풍력에너지연구소(PoWER Center)가 개발에 참여했던 750 kW급 직결형 국산화 풍력발전 시스템의 상용화를 추진하기 위한 출력성능 및 하중 측정을 통한 실증연구가 대관령의 풍력실증단지에서 수행되었다. IEC 61400-13의 규격을 기준으로 수행된 하중 측정의 일환으로 스트레인 게이지의 기계적 하중에 대한 외부 하중부가에 의한 기계적 보정이 추진되었다. 기계적 보정의 수행 중 일부스트레인 게이지가 단락되는 사고가 발생하였으나 비교보정을 통하여 기계적 보정작업을 완수할 수 있었다. 본 논문에서는 외부 하중부가에 의한 기계적 하중의 보정절차를 소개하고, 수행된 기계적 보정시험 과정에 대해 상세히 설명하며 기계적 보정의 결과를 보고한다.
