세계 각국은 에너지 환경, 안보 및 경제에 능동적으로 대처하기 위해 신재생에너지 개발에 국가적 역량을 집중하고 있으며, 그 중 기술의 완성도 및 경제성이 가장 앞서있는 풍력발전 분야의 참여 비중을 점점 확대하고 있는 추세이다. 그러나 풍력에너지 활용의 효율성, 전력의 품질면에서 1~2기 정도의 풍력발전기의 계통연계는 효과적이지 못하기 때문에, 수기에서 수십기의 대용량 풍력발전기로 구성된 대단위 풍력발전단지를 통해 전력을 생산, 공급하는 것이 바람직하다. 따라서, 본 논문에서는 RTDS 시뮬레이터를 이용하여 제주도 한경풍력발전단지의 실시간 시뮬레이션 환경을 구축할 수 있는 3MW급 DFIG 풍력발전기를 모델링하여, 3MW, 5기로 구성된 풍력발전단지를 RTDS를 이용하여 구현하였다.

2030년대는 BT시장이 활짝 열리는 시대로 고도화된 IT기술, 데이터 해석기술, 집적회로 개발기술, 생화학기술 등 모든 영역의 기술이 필요할 것이며, 앞으로의 기술개발은 융합을 전제로 하여 IT와 BT의 융합이 관건이 될 것으로 기술개발의 시너지를 내기 위해서는 관련 산업과 대학이 물리적으로 적정한 위치에 임해야 할 것이다. 우리나라에는 2009년 말 현재 819개의 산업클러스터가 만들어졌으며, 한국산업단지공단이 집적화 된 산업단지에 여러 가지 지원시설, 지원제도 등을 제공하고 있으나 기술융합을 위한 지식재산서비스에 관한 지원제도는 미미하거나 거의 없는 실정에 있다. 이를 위해 우리나라 산업단지의 현재 기능을 살펴보고 문제점을 분석하여 산업클러스터 내의 기업들이 서로 유기적인 협력을 통하여 융합기술 개발의 시너지 효과를 극대화 할 수 있는 길을 모색하며, 특히 한국산업단지공단에 꼭 필요하다고 판단하는 지식재산 관련 지원제도(지식재산지원본부)의 기능과 조직구성에 대한 개념과 산업클러스터 내의 기업에게 지식재산전략 수립을 지원할 수 있는 Flow를 제안하여 산업클러스터의 지식재산서비스 지원방안을 제시하였다.

In this study, two residential complexes, both built in the New City area after 2006 and both composed of over 500 households, were selected to estimate an efficient accessibility and connectivity index using accessibility and connectivity theories and methods from previous studies. With architectural blueprints, the nodes and edges of both residential complexes were drawn out and the accessibility matrixes were derived using these nodes and edges. As a result, the connectivity indices of both residential complexes were lower than 1, the accessibility index of Dong-tan was 86.922 being smaller than the accessibility index of Ilsan, 96.199, and the efficiency index of both residential complexes were similar being 0.26. With these indices it is expected to geometrically estimate the residential complexes and predict the pedestrian passing conveniences.

It is necessary to develop a new location model to support the application of smart technology and confluence in the 4th industrial revolution era. In this study, we propose 'network-type industrial complex' as a method to link several industrial integrated spaces which are dispersed in an area. As a result of conducting a survey of companies in order to develop a new location model, about 89% of companies recognized the necessity of network-type industrial complex. As a condition for activation of the industrial complex, 'complementary function formation', and 'convenience of nodular transportation' were selected. It is expected that it will be possible to supply low-cost, high-efficiency industrial complexes through opening and linking with urban space and infrastructure sharing.

In this paper, we present a new empirical method to estimate the environmental efficiency of decision making units. We propose a model with a new approach that describes a network process consisting of two stages, production and wastewater abatement based on the data extracted from 51 Korean industrial complexes. Taking into account the inter-dependency of two stages, we show a process how to decompose the environmental efficiency into production efficiency and abatement efficiency. Moreover, our new proposed method can be used to explain the information on network relationship between economic growth and environmental protection.

The goal of this research is to identify the planning techniques of high-rise housing estates applying a smart green city concept in order to understand the necessity of integrating 'planning & building' planning techniques and 'smart system' planning techniques and to analyze the current status of application. For the research, firstl, the definition of smart green city was established and high-rise housing estates planning was categorized according to a three space hierarchy, seven planning directions and 17 major features through literature review. Second, 28 'planning & building' planning techniques and 'smart system' planning techniques were derived through literature review and FGI analysis. Last, four cases in Multi-functional Administrative City were analyzed for the current status of application of planning techniques. In conclusion, planning techniques in 'Transportation Network', 'Environment-friendly layout planning of housing', 'Revitalization of green transportation', 'Utilization of new & renewable energy', 'Crime prevention and accident reduction', 'Use of high performance, and efficiency facility' main feature were identified as important planning techniques for Smart Green City and its implications were estimated.

Sustainable industrial development which can minimize an ecological effect by the mankind exertion is recently interested due to an environmental contamination and a resource exhaustion problem. An eco-industrial park (EIP) is a community of manufacturing and service businesses seeking enhanced environmental and economic performance through collaboration in managing environmental and resource issues, including energy, water, and materials. EIP developments which improve a production plant within an eco-friendly greenfield and design a new industrial ecosystem are accomplished recently, which can efficiently re-use the waste and resources from each company within EIP. In this review, the outside and domestic case studies of EIP and cornerstone technologies to develop the EIP, such as energy integration, waste reuse, mass flow analysis, water pinch, and life cycle assessment, are summarized.

Current competition among companies than regional, the time constraints, it is globalization, Tilt the efforts of many to be operated by building the efficient distribution system to reduce logistics costs and improve customer service it is reality's there. Therefore, the need for industrial complexes environmentally friendly can be cost competitive companies perform cavitation region's increased. To build the distribution center these logistics system through a joint of freight and appropriate policy is required. In particular, efficient operation through the system construction of industrial complexes in the logistics system is very important in terms of friendly low-cost urban logistics, the environment. Since the traffic volume which is Jipufa and utilization of network is transported by a more appropriate technicians and means suitable operating model can efficiency is improved. However, despite these advantages, research network design has not been actively conducted due to the complexity of the problem. Therefore, in this study, by analyzing the logistics system, and presents the operating model through a simulation and basic settings for the model of the logistics complex based on the analysis result, the construction of infrastructure of logistics industry complex it is intended to present the article.
