In July of last year, the Korean version of the New Deal National Report Conference was held in the presence of the President, and the "Korean version of the New Deal Comprehensive Plan" was announced as its core strategy. In the field of education, the "Green Smart Future School" project has been included as one of the top 10 Korean New Deal projects. And last year, due to the spread of non-face-to-face classes due to COVID-19, the demand for ICT technology in front-line education sites rapidly increased. Therefore, In this paper, we examine the problems of the wireless network and wired infrastructure of the classroom in the past, and design wired network infrastructure and wireless network equipment for green smart classrooms with high-speed wireless networks that can be used for non-face-to-face and face-to-face classes, and build them in actual classrooms. An example for the following was presented.

The aim of this study is to assess the potential for fusion and convergence in industrial agriculture. First, we analyzed the types of industrial agriculture and applied the agri-business and ICT agriculture. After then, we analyzed the Project Potential Index (PPI) of the agri-business and ICT agriculture using the agricultural enterprise database provided from Rural Research Institute in Korea. The results revealed that Haenam have a high potential for agri-business project because of large number of farmers and annual sales. Wanju was considered as the suitable place for ICT agriculture project because of large area of greenhouse. This study was applied only 7 study area but the methodology suggested in this study could be widely used for assessing potential project various types of industrial agriculture.

Recently interest in energy is becoming increasingly amplified in the world. Green energy is the buzzword of the world's business community as well as governments also leave a green energy seonbongjang of economic recovery. According to the International Institute for Energy, it will be expected to invest in the field of green energy about 7 trillion dollar traslated into 7,000 trillian won around the world by 2030. Thus production, supply, reduce and reuse policies and techniques for green energy came pouring out like a flood. But there is a limit to the fuel supply in order to produce a power generation facility and the power supply that is essential. Reducing produced power efficiently is more important than the increasing of power production. At present, using a method that controls the equipment installed by measuring the environment for efficient control of the energy management of energy-consuming devices that are in use. But the reality is that many policies of national and corporate to did not work to solve a part of the energy savings. In this paper, I proposes a smart energy management system to control the equipment by using the accumulated data obtained with minimal changes in the environment using the energy.

A green technology for reducing energy consumption has become a critical factor in ICT industries. However, for the telecommunications sector in particular, most network elements are not usually optimized for power efficiency. Here, we propose a novel energy-efficient packet switching method for use in an IP network for reducing unnecessary energy consumption. As a green networking approach, we first classify the network nodes into either header or member nodes. The member nodes then put the routing-related module at layer 3 to sleep under the assumption that the layer in the OSI model can operate independently. The entire set of network nodes is then partitioned into clusters consisting of one header node and multiple member nodes. Then, only the header node in a cluster conducts IP routing and its member nodes conduct packet switching using a specially designed identifier, a tag. To investigate the impact of the proposed scheme, we conducted a number of simulations using well-known real network topologies and achieved a more energy- efficient performance than that achieved in previous studies.

Humans and various devices are interconnected using the Internet of Things and are used in various ways. In this study, a synchronization control system with remote locations was constructed using ICT, and a signal system for pedestrians was implemented using the system. PLC circuits were used to implement controllers, through which wireless control signal transmission and reception, LED lamp emission control, and power control were performed. It was confirmed that signal synchronization from the main controller to the remote sub-controller was possible by establishing a controller and pedestrian traffic light system, and lamp signal synchronization of the pedestrian traffic light system installed on both sides of the road was implemented. As a result, it was confirmed that 1:1 remote control or 1:N remote group control was possible, and this result can be used in various fields.

최근 전 세계적으로 문제가 되고 있는 지구온난화의 주범인 탄소 배출에 대한 규제 움직임과 더불어 미래도시철도는 저탄소 녹색교통수단으로 다시금 각광받기 시작하고 있다. 그러나 철도수단 자체의 태생적인 단점과 장기간에 걸쳐 건설되는 인프라와 막대한 투자비용은 철도 투자확대에 여전히 걸림돌로 작용하고 있어 미래도시철도 중심의 교통체계 구축을 위한 획기적인 대안이 절실한 상황이다. 이에 컴퓨터 시뮬레이션으로 배선 설계, 차량운행, 유지보수 등 건설하려는 미래도시철도 시스템을 모델링하고, 단기/중기/장기 예측 및 효율성 분석하여 막대한 투자비용을 절감할 수 있는 미래도시철도 시뮬레이션을 통한 비즈니스 모델을 제시하려고 한다. 본 논문의 구성은 서론에서는 연구 배경 및 필요성, 연구범위에 대해 살펴본 다음, 본론에서 미래도시철도 시뮬레이션, 녹색 성장 비즈니스 모델, 사례연구 결과에 대해 설명한다. 끝으로 미래도시철도 시뮬레이션을 통한 녹색 성장 비즈니스모델의 기대효과에 대해 설명한다.

차세대 전력기술로 불리는 스마트그리드는 ICT와의 융합을 통해 전력을 효율적으로 운용함으로써, 에너지 소비를 줄여 탄소배출량을 줄이는 핵심 솔루션이자 Green by ICT의 대표적인 응용으로서, 글로벌 금융위기와 자원 전쟁에 대한 각국의 대응전략으로 채택되고 있다. 그러나 이와 같은 전세계적인 관심과 의욕적인 노력에도 불구하고, 전력과 정보통신의 컨버전스를 위한 표준의 부재라는 문제에 직면해 있다. [1] 이를 해결하기 위해 미국의 NIST와 유럽의 CEN/CENELEC/ETSI는 경쟁적으로 표준 개발에 전력을 다하고 있으며, 국제표준화기구인 IEC와 ITU 역시 스마트그리드 표준화에 역량을 집중하고 있는 실정이다. 본 고에서는 지금까지의 국내외 스마트그리드 국제표준화 기구의 동향과 더불어 최근 정보통신 입장에서의 스마트그리드 표준화를 진행하고 있는 ITU-T Focus Group on Smart Grid의 표준화 추진 현황을 살펴본다. ITU-T Focus Group on Smart Grid는 특히 한국의 제안으로 설립되고, 지속적이고 적극적인 참여와 주도로 한국의 스마트그리드 표준화 역량이 극적으로 발휘되고 있는 국제표준화 위원회이다.

Currently, the energy consumption rate in buildings is approximately 28.5% of the total energy consumption in Korea. Therefore the amount of the consumption of petroleum resourses is at a worrying level of the blackout. The system of the amount of the Architectural Energy Efficiency Grade [AEEG] is in force by the government to apply the technologies of the Emissions Trading System and the Target Management System to mitigate the Green House Gases for buildings according to the climate change. On the account the mitigation of the Green House Gases and the reduction of the energy, from the view of maintenance and management, for the new and remodeling buildings should be under consideration. The author wants to present the possible ways how to improve the AEEG for the existing buildings by trying to establish the foundation of the BEMs, and by confirming the potential of the energy savings.

Climate technology applied to address climate change requires a comprehensive review such as environmental and social acceptability in addition to economic feasibility. Not only mitigation and adaptation technologies, but also integration of climate technologies into a business model with other relevant technologies including ICT, finance, and policy instruments could enhance technical, economic, and environmental performances to respond to climate changes. However, many climate projects (and business models) are currently not designed to consider adequately complex climate?related issues. In addition, there is a lack of research on assessment systems that can comprehensively evaluate business feasibility of such models. In this study, we developed a system consisting of nine major indicators in four fields to assess climate technology-based business models. Each indicator was weighed using the analytic hierarchy process (AHP) for systematic assessment of business models. The process can be utilized as a tool to guide improvement of climate technology business models.
