With the architectural energy saving technique such as building insulation, airtightness etc., changing the indoor temperature and shortening the air conditioning time etc. are the good methods to practice energy saving in our lives. This study aims to seek a way to realize energy saving under investigation through a questionnaire survey about energy consumption condition and energy saving perception. 93% of the respondents recognized the need for energy saving, and 67% said more energy saving would possible in homes. Viable energy saving way was questioned by five steps method. More than 50% responded 'possible' or 'seems possible' at most of the items. Whereas less than 50% responded 'possible' or 'seems possible' at the items of 'lessening the cooling time' and 'lessening the shower time'. Ages of 50s who responded 'possible' or 'seems possible' was relatively less compared to 30s and 40s.

This study investigated consumers' energy saving behavior and perceptions concerning the effectiveness of their energy saving behavior. A nation wide survey was conducted involving 2000 households in urban areas and the data from 1767 households were used for the analysis. excluding cases with incomplete responses. Descriptive analysis, factor analysis, and regression analysis were applied. The results were as follows. First, electricity saving behavior was classified into three categories: Thrift (reducing energy consumption), Purchase (buying energy saving appliances), and Control (checking the energy consumption). Second, consumers rated Thrift as the best way to save energy. Third, education, age, and household income were significantly related to energy saving behavior and perceptions on the effectiveness of energy saving behavior. Consumers using above average levels of electricity tended not to practice energy saving behavior and not to positively evaluate effectiveness of the energy saving behavior. Lastly, the implications for public policies to promote energy saving behavior are suggested.

The purpose of this study was to analyze and compare the management group' and the teaching group' perception of energy education in Korea. For this purpose, this study carried out a questionnaire survey at schools participating in the energy saving policy. The data was collected from six managers and 171 teachers in middle schools. First, the results indicated that both the management group and teachers have a considerable interest in teaching energy saving practice. How ever the management group showed more preference toward teacher-leading courses, such as lecture, compared to the teachers Second, both the management group and teachers tended to take extracurricular activities. Third, the manager group mostly got energy educational resource from the teacher training program, textbook and teacher's companion. However the teachers mostly did from the mass media. Fourth, compared to the teachers, the managers preferred to allot more budgets to school facilities than to activities related to educating students related to energy. Fifth, the management group pointed out curriculum-making and more budget as the necessity to enhance energy education but the teaching groups did students' interest. Sixth, both the management group and teachers emphasis on the need of energy education.

Multiple nationwide opinion surveys, carried out by the government (cabinet office), major media (national newspapers and NHK), the National Institute for Environmental Studies, and the Atomic Energy Society of Japan, have revealed that the Fukushima nuclear accident has heightened people's perception of disaster risks, fear of nuclear accidents, and increased recognition of pollution issues, and has changed public opinion on nuclear energy policy. The opinion gap on nuclear energy policy between specialists and lay people has widened since the disaster. The results of the Japanese General Social Survey data show that objections to the promotion of nuclear energy are strong among females, and weaker among young males and the supporters of the LDP. These findings are similar to the data collected after the Chernobyl accident. People who live in a 70km radius of nuclear plants tend to evaluate nuclear disaster risks higher. Distance from nuclear plants and the perception of earthquake risk interactively correlate with opinions on nuclear issues. Among people whose evaluation of earthquake risk is low, those who live nearer to the plants are more likely to object to the abolishment of nuclear plants. It was also found that the nuclear disaster has changed people's behavior; they now try to save electricity. The level of commitment to energy saving is found to relate to opinions on nuclear issues.

Purpose: Reducing energy consumption and greenhouse gas emissions is a primary concern throughout the world, and the building sector is a particularly efficient area for making these reductions. In South Korea, the government has recently enacted policies for "Green Growth" that, among other things, enforce regulations in the building certification rating system (BCRS) and reorganize existing incentive systems. Method: In this study, we examined regulations and incentive systems used in the United Kingdom, Germany, and the United States that encourage the use of energy efficient technologies in construction and compared these policies to those used in South Korea. We also disseminated surveys to experts in the fields of architecture, planning and design, and engineering to better understand their knowledge and perception of the BCRS and its incentive systems. Additionally, we sought their recommendations for improving these incentive systems. Result: Based on our comparative case studies of regulations and incentives in other countries, alongside recommendations from experts in South Korea, we concluded that incentive systems in South Korea are limited and require improvement. We make recommendations for strengthening existing regulations and incentives and for implementing new incentive programs.

Cognitive radio technology is still the key technology of future mobile communication systems. Previous studies have focused on improving spectrum utilization and less energy consumption. In this paper, we propose an Overhead Reduced Scheme (ORS) for green cooperative spectrum sensing. Compared to traditional cooperative sensing scheme, ORS scheme divides the sensing time into three time slots and selects the best multi-mode user to report decisions. In consideration of reporting channel deviation, we derive closed-form expressions for detection probability and false alarm probability of ORS scheme based on Rayleigh fading channel. Simulation results show that ORS scheme can improve the perception accuracy while reducing the perceived delay and energy consumption in the process of perception, so as to realize the green communication.

The purpose of this study was to examine the pre-service elementary teachers' perceptions and attitudes toward sustainable development. Subjects were 152 university students, who were surveyed by questionnaire. The instrument consisted of totally 41 items which were constructed by 3 components; 'the perception of concept of sustainable development', 'the attitude toward the relationship between economy and environment' and 'the practical intention of personal change for sustainable lifestyle'. The key findings suggest that most students associate strongly the concepts of sustainable development with their environmental as against economic and social aspect. Most of them incline toward eco-centrism but they had complex attitudes concerning the relationship between economy and environment. They have intention to act for sustainable lifestyle such as purchasing habits, recycling, energy water saving, forms of transportation, nature conservation and education. However, they prefer to act passively than actively in a certain aspect of sustainable lifestyle. Understanding of pre-service elementary teachers' perceptions of and attitudes toward sustainable development will be helpful to work out teaching and learning strategies in environmental education.
