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.

Since the second comprehensive mathematics education plan was announced in 2012, many policies have been implemented based on it. However, due to many changes in various social situations and revision of the curriculum, new plans and policy proposals for mathematics education are strongly required. But, we need to recognize what the changes in the current social and educational situation ask for education in order to make meaningful policy. Therefore, in this study, we intend to develop an appropriate questionnaire to investigate mathematics teachers' perceptions and educational status of mathematics by analyzing former domestic and international studies on the related field and reflecting the educational situation in Korea. When developing questions, experts' opinions were consulted and preliminary on-site survey studies were conducted to maintain the suitability and reliability of the questions. Through these procedure, 33 questions were developed in three areas: teachers' recognition on mathematics education, educational status of mathematics education, and ICT utilization. It will be used as a tool to investigate math teachers' perception and current status of mathematics education and the results from this survey will be useful for developing mathematics education policies for the future.

The purpose of this study is to verify the moderating effect of mobile divide on the relationship between individual characteristics and the use outcomes of smart device. Data was collected through a survey for periods from May 12, 2017, to May 17, 2017. As a result of multiple regression analysis based on collected data, self-efficacy, information seeking desire and culture capital have a positive effect on the use outcomes of smart device. To examine the moderating effect of mobile divide, we conducted a hierarchical regression analysis by calculating the interaction variables of the independent variable and the mobile literacy. As a result of the analysis, it was found that mobile literacy has negative moderating effect between self-efficacy and the use outcomes of smart device. The results of this study can be interpreted as the higher the self-efficacy and information desire for ICT technology users are. In addition, it can be interpreted that the smart device is convenient in the cultural activities of individuals, and therefore, it is highly utilized. Next, among those who have excellent mobile use ability, those who have high confidence in ICT technology can be interpreted as having low utilization because they recognize that the benefits provided by smart devices are familiar and natural. The results of this study confirm that the digital divide problem in the smart environment is influenced by individual characteristics as well as demographic variables. Therefore, we expect the government to set appropriate policies considering the characteristics of individuals.
