World governments and industries have put tremendous efforts for reduction of greenhouse gases. Specifically, IT (information technology) or ICT (information communication technology) is seen to play a pivotal role in green IT since it is deeply penetrated and related to all the industrial and business processes. The objective of this research is to enhance green maturity of a Gangwon province. We first discussed recent trends of green IT approaches/directions and prevailing green readiness indecies. Based on the environmental and industrial characteristics of Gangwon province. a future plan drawn has been examined with regard to a green IT maturity model.

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.

The purpose of this study is to analyze the economic effects of telepresence system for public sector relocation. As a Green IT system, the importance of telepresence is being recognized increasingly as a means to replacing a majority of business trips and thereby reducing greenhouse gases emitted in the process. However, there are only a few related researches that analyze the economic effects of telepresence at the moment. This study conducts the cost-benefit analysis of 157 public sectors which are to relocate from 2012 based on the sample case of National Information Society Agency. The results obtained reveals that telepresence would save about 180 billion won and reduce about 580t $CO_2$ emission. This study are expected to provide the academic framework for organizations contemplating the adoption of Green IT system moving forward.

최근 전 세계는 지구온난화와 기후변화로 상징되는 '환경'위기와 고유가로 대표되는 '자원'위기를 동시에 맞이하고 있다. 정보화의 가속으로 IT 기기의 증가 및 인터넷의 통신량 증가는 IDC 운영에도 많은 영향을 주고 있다. 그 중에서도 대부분의 운영비용이 막대한 전력 소모로 인해 발생하고 있는 실정이다. 이에 따라 IDC 사업자들은 운영 경비의 비용을 줄이기 위해 IDC의 불필요한 인적, 물적 자원의 소모를 줄이며, 고성능 저비용, 저전력 장비 확보에 많은 관심을 기울이고 있다. 제안 시스템에서는 IDC의 서버와 스토리지 등의 IT 장비와 공조시스템과 전력공급시스템 등의 Non-IT 장비의 자동화 통합 관리를 통하여 인적, 물적 자원을 체계적으로 관리하여 이들의 활용성을 높이고, 나아가 IDC의 운영비용 및 효율을 고도화할 수 있도록 하였다.

We propose a green computing which similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product' s lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies.

In developing countries, economically under-privileged are mostly consisted of women, therefore supporting those women signify supporting the local society and the family. Advancement of women's economic status not only contributes to her family but also to the local society, nation, and to the global world as a whole. This paper is a research on local informatization and successful model in e-business for Indonesia, which established interactive research model networking with Korea-Indonesia Research Institution and policy-makers for two years and susggested practical research model through visiting Pekalongan. Through activated interaction between women enterprises and policy makers from Korea and Indonesia, the research paper seeks to create research based network and provide opportunities of information access and business matching to local informatized and e-business enterprises. In research adopted regions, city development project has been accomplished in human, business and environmental field since 2005, and have selected Pekalongan region where infra is settled to certain extent. With the information about Indonesia's city development project, investigation on Pekalongan's current geographical, humanistic status quo, the paper aims to and create Indonesian female e-business professionals, e-business user, e-business producers and provide successful model on Pekalongan's local informatization and e-business.

This article examines how the Chinese government blocks the inflow of undesirable information, focusing on the technical aspect of the control mechanism. Unlike Cuba and North Korea, which regulate the whole Internet, China uses both state-of-the-art technological supervision and labor-intensive physical control due to economic reasons in order to prepare for actors who can threaten the Communist party. The Chinese government will not overlook the inflow of information which can be the link between demonstrations and democratization. This is because stronger protests utilizing information technology will trigger the Chinese government's flexible control based on large scale violation and technology. In this article, we first review the concept of universal internet control involved in internet regulation in nations, and then focus on China's internet censorship and its regulatory control from the '90s to the present. Finally, we analyze how the Chinese government actively controls the internet access by utilizing the relationship dynamics between the central and local governments, depending on protest issue. This thesis will assume that it is difficult for China to become democratized due to its information interception, and search how the government manages the internet.

With progress in industrialization, facilities for generating, delivering, and receiving high levels of electric power are in great demand. The scale of electric power equipment is increasing in both size and complexity. This has contributed to the development of our modern, high-tech and information-based society. However, if the generation of electric power is suspended due to unexpected accidents at power facilities or power stations, a range of equipment the operations of which are dependent on electric power can be damaged, causing substantial socioeconomic losses in an industrial society. A great deal of time and money would be expended to repair damaged facilities at a power station, causing enormous economic loss. In order to detect the deterioration processes of power cables, and to prevent the destruction of power cables, the operation status of power cables should be monitored on a regular basis. We studied the method in order to improve accuracy and reliability for diagnosising the junction where accident occurs frequently. We present the method of data acquisition and statistical processing.
