화석 에너지 고갈과 지구온난화의 위기로 인하여, 미개척 분야인 해양에너지 산업에 대한 전 세계적 관심이 높아지고 있다. 특히 조력발전, 조류발전 그리고 해류발전은 현 정부의 녹색성장기술 신재생에너지에 속한 산업 군으로서, 정부정책 기조와 일치하는 해양 분야의 신성장 동력 아이템이다. 조력발전의 경우 우리나라는 조석간만의 차가 큰 서해안의 지형적 이점을 바탕으로 세계 시장에서 높은 경쟁력 가지고 있으며, 국내에서도 상용화를 위한 조류발전기 개발 및 실증시험을 진행하고 있다. 그러나 해류발전은 그 개념이 국내에서 확립되어 개발 초기단계에 있는 해양발전의 새로운 영역으로서, 전 세계적으로 개발사례가 없다. 해류발전용 해류발전기는 조류발전기에 비하여 크기가 작으나 발전용량이 크며, 개발 및 제작비용이 저렴하므로 조력발전소나 방조제의 수문 근처에 추가적으로 설치하면 매우 큰 시너지 효과를 얻을 수 있을 것으로 기대된다. 본고에서는 조력, 조류 및 해류발전에 대한 개념 소개와 조력발전과 조류발전의 국내외 개발현황 분석 그리고 새로운 개념인 해류발전에 대한 기술적 가능성을 제시하고 기대효과를 간략하게 소개하였다.

In this study, the effect of water level and temperature on the power generation was investigated in a water tank with an aquavoltaic PV module to perform feasibility research for the development of salt farm aquavoltaic system. The silicon solar cell attached to the bottom of each water tank is a 1-cell mini module, and the underwater effects of the crystal phase (19.0~19.9% of single- & 17.9~19.9% of poly-crystalline) of the PV module were investigated, and power generation characteristics for water level (0~10 cm) and temperature (10~40℃) were analyzed. The deterioration coefficients according to the water level and temperature of each single- and poly-crystalline module were investigated at very similar levels such as, -2.01 %/cm and -2.02 %/cm, -0.50 %/℃ and -0.48 %/℃, respectively. Therefore, in salt farm aquavoltaic system, water levels need to maintain as low as possible, and heat-induced degradation is similar to those shown in general land, and no factors have been found to be affected by the underwater environment depending on the determination.

Korea government has established and pursued green technology development strategy as the core of green growth, for example, withdrawal of 27 key green technologies through 'green technology research and development comprehensive plan ('09.1)' since 'low carbon green growth' was proposed as a new national development paradigm. In this study, we performed the Delphi survey of technology levels of 131 strategic product and service technologies derived from 27 key green technologies, utilizing large-scale group of green technology experts. The survey of technology level among main five nations resulted in the world's leading nation (US) versus EU (99.4%), Japan (95.3%), Korea (77.7%), China (67.1%) and Korea was ranked fourth. The technology gap between the world's leading nation (US) and Korea is 4.1 years behind EU (3.9 years) and Japan(3.1 years), but 2.1 years earlier than China. For our nation, key green technologies with high technology level are 'improved light water reactor (90.1%)', 'silicon-based solar cell (85.0%)', 'high-efficiency low-emission car (84.5%)' in order. Depending on the investment type of key green technologies, technology level is represented as short-term (85.0%), mid-term (77.3%) and long-term (71.1%) in order, indicating that lower technology level requires mid-to long-term investment and that the investment type is set appropriate.

본 논문에서는 녹색성장 시대의 교육용 로봇 활용방안을 제안한다. 산업이 발전할수록 늘어나는 에너지 소비에 인간은 많은 악영향을 받고 있다. 고갈되는 화석연료와 그에 따른 환경의 오염 때문이다. 대체에너지로의 변화가 이루어지고 있지만 급격히 바뀌기는 힘들다. 그래서 에너지를 좀더 절약해서 사용하려는 태도를 기르기 위해 교육용 로봇을 활용하여 지도하는 방법을 모색하고자 한다. 구체물을 사용하여 조작하는 것은 초등학생의 인지발달단계와도 맞물려 있으므로 흥미있게 주제에 다가서는 좋은 방법이 될 것이다. 하지만 이에 대한 관련 연구가 부족하여 앞으로 관련 교육과정 개발 및 교재 연구가 절실히 필요하다.

With the development of tourism the desire for a variety of tours for visitors was occurred. Accordingly, to meet the needs of tourists for the development of various tourism products is necessary. In addition to the occurrence of environmental problems needs to develop enviromental tourism products. In this study refocus on rapidly developed templestay and difference of life quality between before experienced templestay and after experienced templestay as product development of low-carbon green was to explore the possibilities. The findings were as follows. First, the increase of age, they satisfacted temples experience like meditation, tea ceremony and Buddhist cultural experience. 11 questions of life quality, 9 items showing significant differences in the quality of life in it will be useful temple stay was used.

An R&D project, 'Carbon Neutral Road Technologies Development', sponsored by the Korean Ministry of Land, Infrastructure, and Transport was performed and sustainable development is being discussed in relation to global climate change. A draft of the green highway certification system, the green highway design and construction technologies for making low carbon eco-friendly roads, and Green Highway Technology Investment Evaluation System (GTIES) for estimating and managing carbon emissions from roads have been developed from the results of the R&D project. A scheme for expanding the application of these technologies and building sustainable road systems by considering the concept of sustainability was proposed in this research.

산업사회의 급속한 발전과 생활수준 향상에 따라 전력수요 및 공급전망에 대한 인식이 점차 강조되고 있다. 에너지자원이 부족한 우리나라는 전체 에너지의 약 97%를 수입에 의존하고 있으므로 전력공급의 정확한 수요예측을 통해서 안정적, 경제적으로 전력을 공급해야 한다. 2001년 전력산업구조개편에 따라 전력시장은 발전부문만 시장에 참여하여 경쟁하는 발전경쟁체제로 발전사업자의 입찰량과 전력거래소의 전력수요 예측 결과를 이용하여 시간대별 전력시장가격을 결정하는 가격결정발전 계획을 수립하고 있다. 본 논문에서는 청정 녹색에너지로 피크시간대에 발전하여 주파수 조절을 담당함으로써 전력계통에 크게 기여하고 있는 수력 발전기의 최적 입찰 전략 및 수력발전 사업계획에 활용할 수 있는 전력거래가격 전망 전략을 제시하여 수력발전사업자의 수익 증대와 전력시장 가격 안정화에 기여하고자 한다.

Global expansion of regulation for carbon emission has brought new industrial regulations and trade barriers while the global economy is promoting economic stimulus through a variety of green investments such as renewable energy development, energy efficiency increase, and environmental improvement simultaneously. Korean government is trying to seek a new opportunity to grow through green investment in this change of business environment and businesses are facing the transition to low-carbon and eco-friendly structure for their survival. It is promoting not only industry structure changes and conversion but also demanding changes of workforce composition and requirement skills. In response to convergence of green economy, manpower development for future skills needs is provided the main impetus for response as well as promotion green growth. This study will analyze human resource development plan due to future skills needs emphasizing on automative industry. Also the study will be researched on the problems of present curriculum of undergraduate and look for improvements tasks. Upon the result, promotion plans for human resource development in other sectors of green car in response to future skills needs in green growth can be found.
