The current study initiated from an action-plan level perspective of revitalizing Green IT (Information Technology) in Korea by building a standardized national Green IT brand. In order to setting up a national level brand, there should be a big quantitative survey for identifying Green IT brand concepts. For this, the current study provides exploratory research results based on preliminary interviews and literature survey before the quantitative survey. The present article suggests a research framework and describes important factors for setting up a national level Green IT brand. In-depth interviews with panels were executed and existing Green IT brands in other countries are summarized and asked for evaluation to a small number of panels. The research results show that (1) National level Green IT brand should include wider concepts of IT, (2) Green IT brand will be more appealed by the public when it is simple, straightforward, and intuitive, (3) Earth, Tree, and/or Water show higher correlation with Green IT concepts. Green IT brand will offer marketing promotion effects to companies who adopt national level Green IT brand as well as increase public use of Green IT in daily life. For this reason, Green IT brand will be a win-win strategy and this should be cared and executed by the related government agencies with long term perspective.

Many companies have integrated the green technology usage into their core business process. This green IT offering addresses the information technology function/industry, which has a role to play in reducing the environmental burdens caused by IT and also providing advanced technology and solutions to reduce environmental problem. In this research, we focus our study on the diverse dimensions of related theories regarding green IT practices, and analyze factors influencing these practices from multi-dimensional context: ecological, industrial, and company context. By integrating the stakeholder theory and resource-based view theory, we introduce the causality model of Green IT. We proposed that initially, ecological context with its social, economic, and political drivers will derive various motives under industrial context (competitive, legitimacy, legislative, and ethical motives). As a response, companies will formulate their strategies driven by these motives (company context). Next, the Green IT strategies will determine the Green IT practices of the company along with the different roles of stakeholders associated with each motivation. We closed our study by arguing that green activities of the firm may have on its economic/financial performance. Discussion and implication for further research are also provided.

Recently, the CO2 emission and energy consumption have become critical global issues to decide the future of nations. Especially, the spread of IT products and the increased use of internet and web applications result in the energy consumption and CO2 emission of IT industry though information technologies drive global economic growth. EU, the United States, Japan and other developed countries are using IT related environmental regulations such as WEEE(Waste Electrical and Electronic Equipment), RoHS(Restriction of the use of Certain Hazardous Substance), REACH(Registration, Evaluation, Authorization and Restriction of CHemicals) and EuP(Energy using Product), and have established systematic green business/IT strategies to enhance the competitiveness of IT industry. For example, the Japan government proposed the “Green IT initiative” for being compatible with economic growth and environmental protection. Not only energy saving technologies but energy saving systems have been developed for accomplishing sustainable development. Korea’s CO2 emission and energy consumption continuously have grown at comparatively high rates. They are related to its industrial structure depending on high energy-consuming industries such as iron and steel Industry, automotive industry, shipbuilding industry, semiconductor industry, and so on. In particular, export proportion of IT manufacturing is quite high in Korea. For example, the global market share of the semiconductor such as DRAM was about 80% in 2008. Accordingly, Korea needs to establish a systematic strategy to respond to the global environmental regulations and to maintain competitiveness in the IT industry. However, green competitiveness of Korea ranked 11th among 15 major countries and R&D budget for green technology is not large enough to develop energy-saving technologies for infrastructure and value chain of low-carbon society though that grows at high rates. Moreover, there are no concrete action plans in Korea. This research aims to deduce the priorities of the Korean green business/IT strategies to use multi attribute weighted average method. We selected a panel of 19 experts who work at the green business related firms such as HP, IBM, Fujitsu and so on, and selected six assessment indices such as the urgency of the technology development, the technology gap between Korea and the developed countries, the effect of import substitution, the spillover effect of technology, the market growth, and the export potential of the package or stand-alone products by existing literature review. We submitted questionnaires at approximately weekly intervals to them for priorities of the green business/IT strategies. The strategies broadly classify as follows. The first strategy which consists of the green business/IT policy and standardization, process and performance management and IT industry and legislative alignment relates to government's role in the green economy. The second strategy relates to IT to support environment sustainability such as the travel and ways of working management, printer output and recycling, intelligent building, printer rationalization and collaboration and connectivity. The last strategy relates to green IT systems, services and usage such as the data center consolidation and energy management, hardware recycle decommission, server and storage virtualization, device power management, and service supplier management. All the questionnaires were assessed via a five-point Likert scale ranging from “very little” to “very large.” Our findings show that the IT to support environment sustainability is prior to the other strategies. In detail, the green business /IT policy and standardization is the most important in the government’s role. The strategies of intelligent building and the travel and ways of working management are prior to the others for supporting environment sustainability. Finally, the strategies for the data center consolidation and energy management and server and storage virtualization have the huge influence for green IT systems, services and usage This research results the following implications. The amount of energy consumption and CO2 emissions of IT equipment including electrical business equipment will need to be clearly indicated in order to manage the effect of green business/IT strategy. And it is necessary to develop tools that measure the performance of green business/IT by each step. Additionally, intelligent building could grow up in energy-saving, growth of low carbon and related industries together. It is necessary to expand the affect of virtualization though adjusting and controlling the relationship between the management teams.

최근에 우리 사회에서 관심을 끌고 있는 키워드는 친환경 혹은 그린이라는 단어일 것이다. 오늘날 우리사회는 산업화에 따른 무분별한 자원의 개발등으로 환경오염에 대한 우려가 가속화되고 있는 상황이다. 그린 IT는 환경을 비롯한 에너지 관련 문제들을 해결하고 기업의 생산성을 높일 수 있는 방법으로 미래 산업 발전에 필요하다. 따라서 본 연구에서는 그린 IT와 관련된 내용을 연구하였다. 그린 IT는 변천과정을 통해 IT에 대한 그린화를 시작으로 현재는 IT를 이용한 타 산업에서의 그린화가 활발히 진행되고 있다. 본 연구에서는 그린 IT에 대한 변천과정 및 각 과정에서의 특성, 대표적 사례들에 대해 기술하였다. 마지막으로 그린 IT에 대한 대표적 융합사례인 스마트워크(smart work)에 대해 조사, 분석하였다.

Eco-friendly or green is a key word which we use in our life. There are examples such as eco-friendly laundry detergent and agricultural products or green car and home, Due to the indiscriminate development, it was caused severe environmental pollution. Green IT is a necessary technology to solve the energy and environmental problems and to increase the productivity of corporations. Therefore, we studied contents related with green IT. The history for green IT has changed from ‘Green of IT’ to ‘IT for Green’. Studies for ‘IT for Green’ progress extensively on today. In this paper, we described a transition progress and characteristics of green IT. Lastly, we analyzed smart work in the examples of the top.

그린 IT는 IT 기반의 친환경 기술을 포괄하는 개념으로서 넓은 범위에서는 유해물질 대체, 에너지 효율화, 대체에너지 등 친환경적 기술을 의미한다. 현재 IT 산업의 흐름은 서버발열 및 데이터센터 에너지 절감 방안 등에 초점을 맞추어 그린 IT를 정의하고 있다. 본 연구는 문헌조사를 통해 그린 IT의 개념을 정의하고, 그린 IT가 나타난 배경과 필요성을 통해 현재 IT시장에 새롭게 등장한 그린 IT의 이슈 및 각 나라별 전략 및 국내의 전략을 비교분석하였다. 이를 구체적으로 살펴보면, 최근 IT 및 데이터센터 시장 전반 향후 변화 및 흐름을 볼 때 그린 IT는 그린 데이터센터 도입에 초점을 맞추어 사업의 방향과 전략을 수립하고 있는 것으로 나타났다. 따라서 본 연구는 국내외 기업의 그린 데이터센터 도입을 통한 그린 IT 구축 사례를 통해서 그린 IT 도입기준과 필요조건, 환경평가 및 설계 그리고 구체적인 추진전략과 향후 과제를 제시하였다.

As global climate changes, the interest in environmental crisis is increasing and a number of inter-national agreements and regulations against this crisis are being established. Global information tech-nology(IT) corporations are building their own pro-environmental green IT strategies to cope with the regulatory measures. Green IT broadly refers to pro-environmental technologies designed to replace hazardous materials, maximize energy effectivity, and find alternative energies. In the current stage of the IT industry development, Green IT specifically refers to the technologies that deal with the server heat generation and the energy reduction in data center. This study defines the concept of Green IT and reviews its origin and necessity. Then, it examines the issues regarding Green IT industry in Korea as well as other countries and compares the Green IT strategies developed in each country. Reviewing the recent development of IT and data center mar-ket enables us to see that overall Green IT strategies focus on the establishment of Green Internet Data Centers. Therefore, this study analyzes the cases in which some domestic and foreign corporations in-troduced Green Data Centers in order to examine the protocol and legal requirements for building Green IT, the aspects of environmental evaluation and design, and specific strategies for launching Green IT strategies and its future assignments. The conclusions of this study are as follows. First, to introduce Green Data Center as a strategy to build Green IT, the government and corporations should cooperate with each other. Partial introduction at the initial stage is desirable because, through the process, mutual trust between the two parties can be built more smoothly. Second, CEO’s determination to build Green IT and continue its operation is indispensable. CEO’s are required to have clear understanding as to why Green IT needs to be built and how it should be constructed. Those who initiate the construction of Green Data Center for Green IT need to know the definition and necessity of Green IT while at the same time understanding the implicit meanings of Green IT. They also need to be aware of future-oriented values of Green Data Center and readjust their corporate business activities in the pro-environmental direction. Finally, not only the CEOs' pro-environmental activities but also the change of mind on the part of all corporate employees is required to realize Green IT. It should be remembered that pro-environmental Green IT starts with minor activities.

Performance evaluation has been done using financial indices which are generally regarded as inappropriate for the organizations which are innovative and progressive. Thus, the Balanced Scorecard(BSC) was developed considering long term performance and invisible performance. This BSC has four perspectives of finance, customer, internal operation, and learning. Based on the BSC, a new BSC has been derived with a fifth view of environmental and social perspective, which is now called as a Sustainability BSC. In this study, we evaluated Green IT initiatives using the Sustainability BSC. The initiatives are categorized as RFID, telepresence, paperless office, logistics management etc. The initiatives were evaluated from the view of five perspectives, resulting in high cor relationships among finance, internal operation, and environmental and social perspectives. Namely, good initiatives from the view of environmental/social perspective are also evaluated as good from the view of finance and internal operation perspectives. In this study, we recommend organizations to introduce Green IT initiatives by showing how Green IT initiatives have contributed to the organizations.

전 세계적으로 환경 친화적이고 지속가능한 경제에 대한 관심이 높아지면서 기업 경영에 있어서도 녹색경영이 중요한 전략으로 급부상하고 있다. 국내에서도 정부의 녹색성장 비전 발표 이후 최근 몇 년간 녹색정보화에 대한 정책이 수립되고 기업들도 다양한 사업 계획을 발표했으 나 소기의 성과를 얻지 못하고 있는 실정이다. 이는 현재 수준에 대한 정확한 진단 없이 이상적인 비전 만을 제시하는 선언적 정책 및 사업 계획이 주로 진행됨에 따른 한계라고 볼 수 있다. 이에 본 연구는 국내 기업의 정보화 수준과 환경 규제 상황을 고려한 녹색정보화 성숙도 진단 모델을 개발하고, 이를 산업별로 대표성 있는 국내 기업에 시범 적용함으로써 국내 기업의 녹색정보화 현재 수준을 진단하고 이를 바탕으로 개선방안을 모색하고자 하였다.

One consequence of the new economic imperative of developing an environment-friendly and sustainable economy has been the growing importance of green management as a corporate management strategy. In Korea, the government has put forth a green growth vision, and followed suit with policy measures reflecting this vision. Companies, in their turn, have announced various new management plans reflecting this green vision. But, thus far, no tangible progress has been made. This is mainly due to the lack of concreteness, both in the government’s policy and green management plans by companies. The government’s green IT vision, for instance, was formulated without an accurate assessment of the current level of maturity in terms of green IT in Korea. This study presents a model for assessing the level of green IT maturity, developed by taking into consideration the informatization and regulatory environments of Korean firms. We use this model to evaluate a sample of Korean firms selected as representatives of their respective industry sectors to assess the overall level of green IT maturity among Korean companies. Improvement strategies, based on the results of assessment, are presented as well.

전 세계 각 나라가 추진하고 있는 경제성장은 환경오염이라는 부작용을 유발하게 되었다. 환경오염은 화석연 료의 과다한 사용으로 인한 이산화탄소의 막대한 배출이 주원인이며, 지구온난화를 비롯한 여러 가지 문제를 유발하고 있다. 그린 IT는 환경오염을 해결하는 방법으로서 최근 각광을 받고 있으며, 또한 IT산업을 발전시키 기 위한 방안으로 주목받고 있다. 본 논문의 목적은 초등학생을 위한 그린 IT 교육내용을 개발하는 데 있다. 이를 위한 다양한 국내외 문헌조사 를 통해 실천지침을 조사하고 분석하였다. 본 논문에서는 초등학생을 위한 그린 IT 교육내용 개발을 위해서, 지식, 기능 및 가치관 차원에서 교육내용을 개발하였으며, 특히 기능차원의 실천지침의 타당성을 검증하기 위해서 초등학교 교사를 대상으로 설문조사결과를 통하여 교육내용을 선별하였다. 본 교육내용은 향후 그린 IT 교육에 좋은 지침이 되리라 기대한다.

While every nation in the world is emphasizing economic growth, we are confronting a side effect called environmental pollution. The main cause of environmental pollution is abuse of fossil fuels which emit carbon dioxide and are causing various problems including global worming. Green IT becomes popular as a method to reduce environmental pollution as well as a method to develop IT industry. The purpose of this paper is to develop education contents of green IT for elementary school students. For this purpose, extensive literature review works have been searched and analysed. In this paper, education contents of green IT are developed for three categories, knowledge, application, and ethics. In order to verify the validity of practical guidelines in application category, 55 elementary school teachers are randomly selected and their responses are gathered and analyzed through thorough statistical work. We expect that the proposed education contents will be guidelines for future green IT education.

복잡계 관점에서 트래픽 패턴, 도시 및 다세포 생물학적 유기체 등이 하나의 창발적인 현상인 것처럼, ‘그린 IT’의 개념 또한 지구 온난화 문제로 인해 인간 세계에서 태동할 수밖에 없는 불가피한 창발적인 현상이다. 복잡계 이론의 관점에서 그린 IT는 무작위한 것으로부터 대단히 복잡한 방식으로 상호작용을 하는 상당히 뒤얽힌 시스템으로 발전할 가능성이 높다. 그렇지만, 그린 IT 시스템 또한 하나의 복잡계라 할 때, 그러한 시스템을 구동시키고 억제시키는 미지의 끌개들이 존재한다. 이러한 맥락에서 본 논문은 그린 IT 시스템의 잠정적인 끌개들을 식별하고, 평가할 수 있는 하나의 새로운 모델을 제안하고, 이를 교육적으로 활용하는데 있다. 구체적으로 그린 IT의 끌개라 할 수 있는 그린 IT 너비-깊이 행렬을 기반으로 그린 IT 진화 및 자기조직화 되어가는 과정을 측정할 수 있는 유형-2 퍼지 시스템을 구축한다.

Emergent process or behaviour can be seen in many places, from any multicellular biological organism to traffic patterns, cities or organizational phenomena in computer simulations. Similarly, the concept of 'Green IT' refers to the way complex systems and patterns arise inevitably among groups due to environmental concerns in real world. Green IT has good possibility to evolve as very chaotic system, in which the number of interactions between components increases geometrically with the number of components, thus potentially allowing for many new types of behaviour to emerge. However, when Green IT system regards as a complexity one, there exits some attractors to derive and control the system. In this context, this paper presents a new model based on type-2 fuzzy logic system to identify and assess the attractors of Green IT system which correspond to Reach-Richness matrix of Green IT.

Most countries have been focused on the CDM(Clean Development Mechanism). According to Wikipedia, the free encyclopedia, CDM is an arrangement under the Kyoto Protocol allowing industrialized countries with a greenhouse gas reduction commitment to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. There are many environmental problems which resulted from development of IT field. The main objective of this paper is to find an effective methodology as an initial stage for applications of green IT in a real life. Therefore this paper addresses worldwide reviews on green IT products.

환경오염의 상당부분이 기업 책임으로 인식되면서 기업의 그린 경영에 대한 요구가 증가하고 있다. 이러한 외부환경하에서 기업의 그린 경영을 위해서는 그린관련 규제준수, 그린의 전략적 활용을 포함한 새로운 거버넌스 체계가 요구되고 있다. 본 연구에서는 현장에 적합한 거버넌스 체계를 도출하기 위하여 거버넌스 및 IT분야의 전문가 중심으로 FGI 방법을 이용하여 그린 IT 거버넌스 체계를 도출하였다. 본 연구결과인 그린 IT 거버넌스 체계는 그린IT 중점영역, 그린경영목표, 그린 IT목표, 그린IT관리절차 및 프로세스로 구성되었으며, 그린 IT 거버넌스 체계에 포함된 프로세스별로 기업내 실무자가 그린IT활동을 수행하고 경영자가 그린 IT 수행과정 및 성과 통제에 활용할 수 있는 체계와 절차를 제시하였다.

Recently, following increased concern about green, people think that the pollution problems are cause of firm's product activities. So, firm's burden increased to protect nature and save energy during produce the goods. To keep the regulation and use the strategy methods, need to new Green IT Governance Framework(GITGF). FGI(Focus Group Interview) was used to carry out the research that is not mature. In this paper, we proposed the framework that is composed of green IT domain, business purpose, IT purpose and management process. GITFG is useful method to govern the corporate activities in the green IT Governance perspective.

Sustainable Information Technology (IT) and Sustainable Information Systems (IS) were synonymous with Green IT-IS until recently the studies focused on sustainable IT-IS encompassing the interaction between economy, society, and environment. Here, is an attempt to understand the development in the emerging field of Sustainable IT-IS from Green IT-Green IS. The studies in the area of Sustainable IT-IS spare address diverse topics. This study attempts to provide a framework for the field of research and indicate potential research directions in the sustainable IT-IS domain. A detailed comparative analysis approach of 296 papers has been used to understand the progress of management research in Sustainable IT-IS vis-à-vis Green IT-IS. The review analyses the collated literature to understand the trends across the study period, development across various economies/ geographies, methodological approaches used, behavioral and theoretical aspects investigated, and finally, develop a taxonomy based on identified theses in the field of study. The study highlights that developed countries focus more on studies on the Sustainable IT-IS domain compared to other economies. It was evident that sustainable IS has received very limited focus. The study identifies 7 major themes and 29 subthemes forming the area of study during the evolution of Sustainable IT-IS through Green IT-IS. Subsequently, taxonomy was proposed to identify future research initiatives for investigation. The review comparing the evolution of research on managerial issues on Sustainable IT-IS vis-à-vis Green IT-IS is provided perhaps for the first time. The study provides an avenue for future research in the upcoming domain of Sustainable IT-IS.

While many surveys show very positive attitudes on the part of consumers towards eco-friendly products, the market share actually reflecting green IT purchases remains low in most countries. The motivations behind green IT purchase behavior are still obscure. Several studies have addressed the question of green IT diffusion from economic and normative viewpoints in an attempt to interpret IT adoption behavior. This study comes at the question from a different angle, namely negative frame, examining threat and coping behaviors using the Ordered Protection Motivation (OPM) model and threat appraisal theory. The results show that attitudes toward fairness and positive change, which are precedents of threat appraisal, play an important role in determining threat appraisal. Perceived threats in the green IT arena include habit change and ecological change. Appraisal for coping with these threats directly affects initial adoption behaviors regarding available green IT, and then indirectly encourages the purchase of new green IT products.

본 논문에서는 요사이 대두되고 있는 환경 변화에 따른 기후 변화 및 온난화의 문제의 주범 인 CO2 의 감축 문제를 해결하기위한 방법론에서 등장한 탄소배출권 대하여 알아보며, 배출권거래에 따 라 탄소 배출권 거래시장이 형성 되었고, 이러한 현상은 각국이 온실가스 즉 CO2 의 감축과 각국의 성장 이 함께 움직이는 현상을 보이고 있다. 이렇게 국가 간의 CO2 발생이 국가 성장에 영향력을 나타내기에 국가 간에는 자국에서 발생되는 CO2 양에 대한 객관적이고 정확한 평가가 중요한 이슈로 떠오르고 있 다. 그리고 CO2 양에 대한 평가가 국가 간의 이해 및 분쟁의 소지로 발전되어가는 현상을 보이고 있다. 이러한 각국의 온실가스 감축평가에 대한 이해관계를 중재 할 수 있는 평가 규정이 현실화되기 위하여 서는 각국에서 이해하고 납득 할 수 있는 정확하고, 객관적인 평가지표의 개발이 시급한 실정이다. 즉 각국에 합당한 온실 가스 감축의 양을 결정하고, 감축결과를 정확하고, 객관성 있게 평가하는 평가지표 가 요구된다. 이러한 평가지표를 통해 각국의 온실가스 감축이 객관화 될 수 있을 것이다. 이러한 이유 로 탄소 배출권에 대한 거래의 장소인 탄소 시장과 탄소배출권의 주목표인 CO2 의 감축에 대한 객관적 평가방법에 대하여 IDC를 중심으로 조사하여, 가장 합리적이고 최적화의 평가 지표의 개발을 위한 탐색 적 연구를 시도했다. IDC를 중심으로 객관적으로 평가할 수 있는 평가지표로는 그린 그리드(Green Grid)가 발표한 일반적으로 사용 하고 있는 PUE(Power Usage Effectiveness), PUE 역의 지표인 DCE(Datacenter Efficiency), DCE의 백분율의 형태로 변환한 지표인 DCiE(Data Center Infra Efficiency), 전체에너지를 수행능력으로 보완한 지표인 DCPE(Datacenter Performance Efficiency), DPPE(Datacenter Performance Per Energy)에 대하여 특징 및 보완점을 조사 연구하여, 이 지표들의 문제점을 제기하고 대안으로 DUE를 제안 하였다. DUE는 PUE의 데이터센터의 IT 기기이외의 에너지 절감 성능은 평가할 수가 없다는 문제점의 대안과 IT 기기의 에너지절감 성능에 태양광발전이나 풍력 발전 등의 자연에너지를 얼마만큼 활용하고 있는지 등도 평가할 수 있는 새로운 평가지표로 구성되어있 다. 하지만 본 논문에서 제시한 평가지표는 IDC를 중심으로 개선되어진 평가지표인 만큼 앞으로 연구를 통하여 산업 전반에 걸친 일반적인 평가지표로의 개발이 요구된다.

In this paper, It look for solution of a climate change and the warming. The solution reduce CO2. The method is carbon dioxide emissions. and then it is ETS(Emissions Trading Scheme). At IDC I research an objective evaluation method for reducing the CO2 . I study PUE(Power Usage Efficiency) and TPUE(Total Power Usage Efficiency). We’ve discussed how to measure total facility power. The short summary is it must be measured prior to all UPS and power conditioning at medium voltage. If high voltage is delivered directly to your facility, you should measure after the first step down transformer. If your facility is delivered low voltage, then ask your power supplier whether it be the utility, the colo-facility owner, or your companies infrastructure group, the efficiency of the medium to low step down transformer at your average load. Add this value in mathematically. This is not perfect but it better than where we are right now when we look at a PUE. Please consider helping to evangelize tPUE and use tPUE. And, for you folks designing and building commercial servers, if you can help by measuring the Productive IT Equipment Power for one or more of your SKUs, I would love to publish your results. If you can supply Productive IT Equipment Power measurement for one of your newer servers, I’ll publish it here with a picture of the server. The Green Grid proposed the use of Power Usage Effectiveness (PUE) and its reciprocal, Datacenter Efficiency (DCE) metrics, which enable datacenter operators to quickly estimate the energy efficiency of their datacenters, compare the results against other datacenters, and determine if any energy efficiency improvements need to be made. Since then, PUE has received broad adoption in the industry, but DCE has had limited success due to the misconception of what data center efficiency really means. As a result, this paper reaffirms the use of PUE but redefines its reciprocal as datacenter infrastructure effi ciency (DCiE). This refinement will avoid much of the confusion around DCE and will now be called DCiE. In the long term, The Green Grid is developing metrics to measure data center productivity as well as efficiency metrics for all major power-consuming subsystems in the datacenter. To promote these metrics and drive greater datacenter energy efficiency for businesses around the world, The Green Grid will publish future white papers that provide detailed guidance on using these metrics. We will also continue to collaborate with organisations such as the EPA, ECMA and Climate Savers that promote a similar goal and vision. They are not enough. PUE has the problems that evaluate the power saving performance of only IT machinery. PUE(Power Usage Effectiveness), DCE(Datacenter Efficiency), DCiE(Data Center Infra Efficiency), DCPE(Datacenter Performance Efficiency), DPPE(Datacenter Performance Per Energy), etc has some problems. DUE solves the problems. DUE contain natural power facility. It measures the power saving performance of IT machinery and tools. and It measures natural energy use. but, DUE is case of the CO2 measure in IDC. From now on, You must study it. Development to the general evaluation index is demanded.

산업화에 따른 환경문제는 전 세계적으로 큰 이슈가 되고 있으며, 이중 에너지 절감 및 CO2 배출 감소문제는 심각한 도전으로 인식되고 있고, 에너지 소비와 산업폐기물의 양산이 많은 IT분야가 새로운 환경적 패러다임 변화에 적극적으로 대응하기 위해서는 그린IT 분야로의 전환이 필요하다. 이러한 필연적 변화는 사회적 현상에서도 살펴볼 수 있으나 기술측면에서도 살펴볼 수 있다. 기술의 변화는 전문가들의 견해를 통해 검토해 볼 수도 있으나 본 원고에서는 객관적인 특허정보를 활용하여 그린IT의 주요 활동국가와 기업, 부각되고 있는 기술분야에 대하여 개괄적으로 살펴보고, 향후 국내 그린IT 분야를 추론해보며 결론을 맺도록 하고자 한다. 여기서 살펴보는 그린IT는 에너지소모량의 절감과 전력소비를 줄이는 분야로 한정하여 검토하였다.

최근 미국에서 TV를 제어할 때 기존의 리모컨 대신에 손동작을 이용하는 기술이 상용화되었다. 하지만 그것은 리모컨의 역할을 사람의 손동작으로 TV가 인식하는 응용기술로 써 실질적인 에너지 절약과는 거리가 있었다. 본 논문에서는 TV가 사용자의 모습을 영상처리를 하여 실제로 시청을 하지 않는 경우 전원을 제어하며 에너지를 절약하고 시청하지 못한 컨텐츠는 자동 저장하여 사용자가 원하는 시간에 다시 볼 수 있게 하는 기술을 제안한다. TV에 설치된 카메라 모듈을 통해 주기적으로 사용자의 모습을 촬영하고 Gabor 필터를 이용한 영상 처리로 사용자의 상태를 감시하여 잠이 들었다고 판단될 경우 TV 전원을 자동으로 차단시킨다. 스마트 미터를 도입한 실험 결과를 통해 제안 시스템을 사용하게 되면 기존대비 약 4.8배의 전력 소모를 줄일 수 있음을 확인할 수 있다.

Recently, the technology that controls televisions through users' hand movements instead of remote controls has been commercialized in the United States. However, it is only the substitutional applied technology of remote controls that recognizes a certain set of functions, so that this technology does not effectively economize the energy used by the equipment. In this paper, this new technology will be proposed. The technology provides a solution to prevent wasting power by image processing when the television is not being used. In addition, the new technology is able to record programming contents while the television is off, thus the user is capable of possessing a choice of which time the contents are being watched. Moreover, the motions of the user are continuously captured by the camera module installed in the television. The image data processed through image processing such as gabor filter delivers the method to monitor the state of the user. If the user falls asleep, the television shut itself down to save the power. Experimental results of the introduction of smart meters through the proposed system, if you use about 4.8 times compared to existing models that can reduce power consumption can be found.

환경문제가 부각되고 글로벌 환경위기에 대응한 저탄소 녹색성장 정책에 따라 초·중등학교도 저탄소 녹색성장 구현을 위한 방안을 마련해야 할 것이다. 그러므로 본 논문에서는 교육정보화를 통한 초·중등 녹색학교를 만들기 위해 ‘IT 정보자원의 그린화’와 ‘교육정보화를 통한 교육환경의 그린화’로 구분하여 추진과제를 제시한다. ‘IT 정보자원의 그린화’는 그린 IT 제품 도입시 필요한 가이드라인과 IT 제품 재활용을 고려한 폐기 방안을 제안하고, 친환경 정보 인프라 모델을 제안한다. ‘교육정보화를 통한 교육환경의 그린화’는 학교 구성원들인 교사․학생들이 지켜야할 그린 IT 실천방안 및 교육활동을 제안하고. IT를 활용한 저탄소 교육환경으로 전환을 추구하는 다양한 교육정보화 서비스 활용을 제시한다. 앞으로 이러한 제안이 학교현장에 실현되면 녹색학교 구현에 도움이 될 것으로 기대한다.

Elementary/secondary school must make the scheme for the Low Carbon Green Growth embodiment because of the environmental problems and the Low Carbon Green Growth Policy for responding to global environmental crisis. This paper proposes a plan to make green elementary/secondary school model through the educational information. It divides into 'Greening of IT Information Resources' and 'Greening of Education Environment' through the educational information'. It is expected to embody Green School if these projects are realized to the elementary/secondary school. 'Greening of IT Information Resources' suggests the guideline necessary to the introduction of IT products, the method to abandon considering recycling IT products and environmental information infrastructure model. 'Greening of Education Environment' proposes the IT green practice method for teachers and students to keep and shows the practice of various educational information service to seek a conversion to low carbon education environment. It is expected to embody Green School if these projects are realized to the elementary/secondary school.
