에너지에 대한 수요가 급증하게 되면서 에너지부족문제에 대한 크게 대두되기 시작하였다. 특히 에너지 사용급증은 에너지 부족문제 초래뿐만 아니라 화석사용연료 사용 급증으로 인한 이산화탄소 배출증가 및 에너지 비용증가가 국가적 이슈로 자리잡기 시작하였다. 따라서 이러한 문제를 해결하고자 여러 기관들에서는 에너지관리시스템 개발에 착수하기 시작하였다. 그러나 이러한 시스템은 별도의 관리자 및 운영비용이 들기 때문에 에너지 절감이득에 비하여 비용에 대한 혜택이 없는 중소형 건물 적용에 어려움이 있었다. 따라서 이러한 한계점을 극복하고자 KT 융합기술원에서는 에너지통합운영시스템이 개발하였으며, 중소형 건물에도 적용이 가능하다는 장점이 있다. 본 고에서는 다수의 건물 관리가 가능한 건물통합에너지관리 최적운영시스템 개발에 관하여 다루어 보고자 한다.

Integrated science for high school is required in the present Korean National Sixth Curriculum and the Seventh Curriculum which will be effective in 2002. Currently, most science teachers in secondary school have concerns about teaching integrated science subjects and this continues to raise a significant problem for practical implementation of integrated science education in schools. In this paper, we discuss two reasons for these concerns that our analysis revealed: 1) Science teachers do not understand how to implement integrated science education and 2) there are insufficient teaching-learning materials supporting integrated science. Three different approaches to integration that have been suggested to overcome the problem of implementation are outlined here. They are the knowledge centered, social problem centered, and individual interest centered approaches. Reported here are the first two steps we undertook in preparation for testing the relative effectiveness of these approaches. First, we analyzed the content of the Korean Sixth and Seventh National Science Curricula, seven Korean integrated science text books, the American National Science Education Standards, and the American Association for the Advancement of Science Benchmarks looking for common themes. We identified in the analyzed materials the common themes: energy conservation, energy transformation, energy transport, energy degradation. We then used their energy related content to organize sets of concept structures, one set for each of the three approaches. These concept structures will provide the foundations for the development of integrated teaching-learning energy plans to be used in our research into the effectiveness of the approaches.

Trends of food and energy consumptions in South Korea, North Korea, and the Korean Peninsula were shown and consumptions of food and energy for the integrated Korean Peninsula with several Cases were predicted, and the directions for the environmental resources management were suggested in this study. The Food Supply Quantity, the Protein Supply Quantity, and the Food Supply of North Korea were less than those of South Korea, the Eastern Asia, and World after 1990s. However, it is expected that the food consumption in North Korea will increase, if two Koreas are integrated. If the Food Supply Quantity of North Korea is the same as that of South Korea with the maximum projected population of integrated two Koreas by 2055, the food consumption in the Korean Peninsula would increase by 25% compared with the 2011 food consumption of integrated two Koreas. Thus, the choice of diet should be carefully considered and the increase of agricultural productivity is required. Energy consumption in North Korea is very small comparing to that of South Korea and fraction of coal in energy usage of North Korea is very high. If the energy consumption per capita of North Korea after integration be the same as that of South Korea in 2011, the energy consumption in the Korean Peninsula would increase by 45% compared with the 2011 energy consumption of integrated two Koreas. To minimize the environmental effects caused by energy consumption, the energy plan with the reduced fraction of coal in energy supply of North Korea should be adopted and advanced technology with higher efficiency should be applied to establish or expand the energy facility in North Korea.

South America has vast energy resources with the renewable and non-renewable sources. However, many countries in the region are unable to guarantee adequate energy security both of energy supply and demand. Currently the possibility of energy security is high through regional energy integration based on the potential economic benefits. The difference of regulation system with the individual countries in the region impose strong barriers to integration process. Security of energy supply and its demand as well is fundamental issues in this region and regional energy cooperation is essential for getting rid of the insecurity of energy supplies. Despite of this problem, currently Latin American countries made a great effort to make multilateral energy security regime through projecting great energy infrastructure network(e.g. IIRSA) or mechanism especially in South America, which can give countries access to the region's reserve supplies by providing regulations and pricing mechanism with a shared energy market in this region. Brazil's active leading in the formulation of such movement toward energy security integration and participation of energy infrastructure network is good initiative to enforce this great energy security change. Politically and economically, Brazil's geographical position and the level of market size and oil and natural gas resources, in addition the leadership in renewable energy sources make it a sound candidate to take over the coordination of the secure integration of region's energy market. However, on the conditions of existing many obstacles such as, control of the output of the region's power plant, energy flows, the environmental matter within local community must be overcome to make more advance process and steps. Finally, to secure more institutional approach, this region must settle regional disputes resolution regime urgently.

In this paper, an integrated simulation model for designing multi-agent system based DEMS (distributed energy management system) in stand-alone micro-grid system is proposed. In the design of the EMS(energy management system), the multi-agent based DEMS are more effective than conventional centralized EMS, but it is difficult to design the DEMS by general design tools for power system because of various states of a microgrid system during operation of stand-alone mode. Also, since performance test of the DEMS using a real system is inefficient, an integrated simulation model is required for designing an effective multi-agent system based DEMS. The proposed model consists of Matlab/SimPowerSystems based simulation model of the microgrid system and the Multi-agnet based DEMS designed by Matlab/StateFlow tool. In order to show the effect of the proposed model, the model outputs are analyzed for specified operation conditions.

Damage occur frequently around the world on climate change and the main cause of greenhouse gas emissions regulation is growing. To this end, the government has built integrated management system for national building energy. The building energy information is total 6.8 million complex. Integrated management system for national building energy database are matched building registers information and energy information of the supply agencies. However, the matching process has its limitations so advanced work is in progress continuously. This study analyzed integrated management system for national building energy database quality and limitations and deduce improvement plan to increase system reliability and availability. The existing database matching average rate is 85.6%. 58.2% of the total non-matching data type has no building information. To ensure the ease of new database matching and the accuracy of the existing database matching, address standarization and building properties system are needed between building information and energy information. Also, The system construction is required to include information on other energy sources like petroleum energy which has high proportion of non-urban areas and small residential areas and renewable energy which has high potential in development and utilization.

70년대 두 차례의 유류파동은 에너지자원의 중요성에 대한 기존의 인식을 급속도로 변화시켰으며, 이와 아울러 신대체에너지를 중심으로 한 신기술의 개발여부와 관련하여 에너지 기술평가모형의 수요를 급증시켰다. 이에 지난 십여년간 구미제국을 중심으로 다양한 에너지신기술을 평가하기 위해 다양한 분석기법들이 개발되어 왔으며 이러한 평가기법들을 총괄적으로 지칭하는 에너지기술평가모형(Energy Technology Assessment Models)은 에너지신기술의 경제적, 기술적 특성과 에너지시스템내에서 신기술의 잠재적 역할을 사전 평가하면서 국가적 차원에서의 에너지연구개발 정책을 수립하는데 널리 이용되어 왔다. 본 연구는 국내 에너지 연구개발 관련자들의 이해부족과 데이터베이스의 미비 등 여러 가지 제약요인들로 에너지기술 평가모형이 널리 실용화되지 못하고 있는 현실을 감안하여 경제/에너지/환경/기술개발정책에 있어서의 에너지부문의 역할을 장기적으로 재평가하고 특히 기존 에너지문제의 제약요인인 환경문제 해결을 위한 에너지 수요관리 평가의 개발 필요성에 부응하기 위하여 기존의 거시 경제적 에너지공급모형과 최근 미국, EU등에서 발전시켜 나가고 있는 경제/에너지/환경/기술개발의 통합모형을 문헌조사를 통해 비교,분석하였다.
