Countries are promoting Green New Deal policy to cope with global warming and climate change as a result of economic growth and overcome the economic crisis caused by the coronavirus 19. The role of ICT technology is crucial in realizing the Green New Deal policy, and standardization of ICT technology should be preceded. This paper examines domestic and foreign Green New Deal policies and analyzes trends in ICT standardization activities. Based on the analysis, we propose standards that should be developed for the eight major projects in order to successfully realize the Korean Green New Deal. A strategy to promote ICT standardization for the zero energy project in public facilities as an example was proposed. In addition, we present ways to resolve difficulties in realizing ICT standardization policies related to Korean Green New Deal. Through this study, it is expected that the Korean Green New Deal policies, which is being promoted at the pan-government level, will be effective based on ICT standard technology.

As the response to climate change becomes a more pressing global issue, so do expectations for climate change in the green information and communication technology (ICT) industry and the possibility of solving environmental problems through ICT. However, because the green ICT industry is still in its early stages, there is little research on it. Understanding the startup ecosystem in the industry is helpful for recognizing innovation trends in emerging technologies such as green ICT. In this regard, this paper investigates the current state and characteristics of the green ICT ecosystem and presents implications based on an examination of startup venture capital investment trends and submarket identification in the green ICT industry as emphasized by the carbon neutrality paradigm shift. The analysis included 4,807 companies and 3,990 funding records, as well as exploratory data analysis and "k-means" clustering techniques.

The world today has reached a certain level where it is impossible to get the quality education at the tertiary level without the use of Information and Communication Technology (ICT). ICT has made life better, communication easier and faster, teaching and learning more practical through computers and other technology based learning tools. However, despite these benefits ICT has equally contributed immensely to environmental problems. Therefore there is the need to use ICT resources efficiently in universities for environmental sustainability so as to save both the university environment and the world at large from the effects of global warming. This paper evaluates the carbon footprints from the use of ICT devices and comes up with a proposed green ICT framework to reduce the carbon footprints in universities. The framework contains techniques and approaches to achieve greenness in the data center, personal computers (PCs) and monitors, and printing in order to make ICT more environmentally friendly, cheaper, safer and ultimately more efficient. Concerned experts in their respective departments at Asia Pacific University of Technology and Innovation (APU) Malaysia evaluated the proposed framework. It was found to be effective for achieving efficiency, reducing energy consumption and carbon emissions.

Recently, the world faces a global environmental crisis by the increase of energy consumption and global warming. Since the crisis directly affects political, economic, social, and environmental areas, many countries prepare Green ICT policy to overcome it. However, although Green IT policy provides many benefits by solving environmental pollution and increasing energy efficiency, Korean government did not prepare measures by the policy. The purpose of this study is to suggest priorities of political goals for maximizing the efficiency after introducing Green ICT policy in Korea. Major variables are drawn for the analysis, and they are eco-friendliness, technology evolution, economic efficiency, energy efficiency, and stable supply of energy. The variables are suggested based on 'Low Carbon, Green Growth Act', then the survey was conducted to policy expert using AHP(Analytic Hierarchy Process) and ANP(Analytic Network Process) for prioritizing variables. As a result of the AHP, it is derived in the order of eco-friendliness, technology evolution, economic efficiency, energy efficiency, and stable supply of energy. The ANP result shows in the order of technology evolution, energy efficiency, economic efficiency, eco-friendliness, and stable supply of energy. The research is conducted to analyze the priorities of goals for Green IT policy, and the analysis results are possible to use as a practical guideline for establishing associated policies in the future.

Recently, the global warming phenomenon has been taken notice of. The global warming phenomenon has given enormous bad impact to social economic fields as well as ecological areas by rising sea levels and weather calamities. To cope with the phenomenon most developed countries adopted the Kyoto Protocol to reduce greenhouse gas emissions. To achieve the target of the Kyoto Protocol, the developed countries are operating organization-run green quality assurance and labelling systems with their standardized methods to evaluate the environmental and greenhouse gas impact for ICT products and services. This paper introduces several countries standards which can be applied to evaluate the reduction effect of greenhouse gas emission and green ICT quality assurance which also can be applicable for recycling and managing of ICT products. This paper is expected to be used as a policy data for ICT related government bodies and industry areas.

This study was conducted to derive the optimal estimation equations for deriving the green and dry weights of Larix kaempferi (Japanese larch) and Pinus rigida (Rigida pine), which are major coniferous tree species in South Korea. The equations were then used to develop weight tables. Table development began with the sampling of 150 L. kaempferi and 90 P. rigida trees distributed throughout the national scale, after which green weights were measured on-site. Samples from each stand were then collected, and their dry weights were measured in a laboratory. The equation used to calculate green and dry weights was divided into a one-variable formula that uses only the diameter at breast height (DBH) and a two-variable equation that employs DBH and height. The equations used to estimate the green and dry weights of logs were divided into one- and two-variable equations using DBH. Statistical data, such as the fitness index (FI), root mean square error, standard error of estimation, and residual diagram, were used to verify the suitability of the estimation equations. Applicability was examined by calculating weights using the derived optimal equations. The equation W = bD+cD² was used in measurements involving only DBH, whereas the equation W = aD^bH^c was employed in cases involving both diameter and height at breast height. The FI of W = bD+cD² was 0.91, while that of W = aD^bH^c was 0.95, both of which are high values. With these estimation formulas, weight tables for the green and dry weights of L. kaempferi and P. rigida were prepared and compared with weight tables created 20 years ago. The green and dry weight tables of both species were larger.

Purpose: In this study, the luminance measurement analysis results of the smoke generation state are considered for visual signal display light color for real-time escape guidance in the underground common area. Method: We will analyze the scattering characteristics of light in the atmosphere and optical technology based on the visibility theory, and try to classify the elemental technology as a guidance function through a prototype of a visual signal display device for evacuation guidance. Result: In the experiment conducted under the smoke-generating condition, the results were derived with low luminance ratio and good visibility in the order of red, green, and yellow. However, this result is different from general lighting in which color rendering is considered, and is limited to signals for signals and detection. Conclusion: A conclusions were drawn by reflecting both the luminance measurement results in the smoke generation situation and the preference survey results conducted in previous studies for the light color of the visual signal for signal and detection. When events such as smoke occur, it is better to use the escape guidance visual signal in red or green.
