This study identified the relationship between adolescents' alienation and stress responses, and examined the mediating model of smart media addiction moderated by behavioral activation system (BAS) on alienation and stress responses. Participants were 361 male and female students in middle and high schools located at Seoul metropolitan area. PROCESS Macro 3.5 Model 7 was used for analysis of the moderating mediating effect. Results revealed that adolescents' alienation and BAS were positively correlated with smart media addiction and stress responses, while smart media addiction was positively correlated with stress responses. In a moderated mediating model for stress responses, there was significant interaction effect of alienation and BAS; conditionally indirect effect of alienation was not significant in groups with very low BAS. These findings suggest that adolescents who feel alienation are more likely to experience stress responses by overindulging themselves in using smart media. The moderating effect suggests that this effect is stronger with higher levels of BAS.

This study was inspired by the issue that the fundamentals of education have been overlooked, as today's smart education policies established in the knowledge-based information society of the 21st century have only focused on building digital environment and its efficiency. To carry out the study, the media education of Germany, which is equivalent of Korea's smart education, was analyzed to obtain implications for Korea's smart education. In Germany, the media education has been managed by the country ever since the information society has begun. Since 2009, the media education has become a requirement for all schools in every state. Thus, the current media education policy of each state has been analyzed, which revealed the following common characteristics. 1) The media education is closely linked to existing curriculum and education, rather than being conducted separately with different standards. 2) The media education is being conducted in a democratic manner by actively reflecting the exemplary cases of school teachers, rather than following the instructions and guidelines from the government. 3) The media education deals with the character and identity of young students, based on their basic understanding of information society, which are essential for a successful life in the upcoming society. Unlike the first and second implication linked to the method and procedure of media education policy, the third implication is the basic purpose of media education, which is also the key implication of this study. The media education policy of Germany, which is being conducted with its own educational philosophy, offers significant implications for Korea's smart education policy. In Korea, the education only revolves around device-based environment innovation or content development. It should be noted that the purpose of smart education is developing smart individuals who can bring better, happier, and more successful society - rather than establishing a smart environment. Therefore, the focus of discussion on Korea's smart education that revolves around environment, infrastructure, device utilization, and contents development should be changed to the character and identity of students, which are required in the future smart era. That's when 'human-based' educational revolution, instead of 'device-based' classroom revolution can begin.

This study analyzed the digital divide of Korean senior citizens through the preference for smart media. Targeting two media out of mobile internet and mobile social media, the media dependency ratio and the trend of people in their 20s-60s were verified. Regarding the dependency ratio of young people(20s) and senior citizens(60s), in case of mobile internet, people in their 60s were average 8.6% while people in their 20s were average 38.9%, so that the ratio of senior citizens was lower by 30.3%. In case of social media, people in their 60s were average 1%, which was 7.1% lower than people in their 20s(8.1%). And this divide was the digital divide shown in the informatization process through the trend of internet use of senior citizens in their 60s or up. Thus, as the policy measures for solving the digital divide of senior citizens, it would be required to continuously develop the digital cultural programs for senior citizens, to expansively perform the government subsidiary policies like additionally providing the essential information to senior citizens, and also to expand the smart-based infrastructure for senior citizens' participation in economic activities.

With the expansion of digital media platform, there has been a new conceptualization about public function of public broadcasting in and around European countries. Although there are differences between countries, Universal Access including smart and Internet media has been emphasized in Britain and France. However, there is lack of public discussion on service strategy of Internet and smart media platform when public function of public broadcasting is discussed. Therefore, this study tried to investigate not only the public function of public broadcasting in the field of Internet and smart media through audience research but also how the national public broadcasting stations ensure public interest and competitiveness in the field of Internet and smart media platform. The results suggested that smart phone users evaluated real-time broadcasting and VOD are the most important services among the public functions which public broadcasting stations have to persue. Futhermore, the users showed high intension to use when the free real-time broadcasting service is offered. Therefore, public broadcasting stations have to improve the social recognition on necessity and public interest of public broadcasting stations through the free real-time broadcasting services on Internet and smart media platform. And policies which can ensure competitiveness in the era of digital media are needed to become important broadcasting institute.

Smart space is a technology that supports humans by interacting with the surrounding environment. Smart space has a built-in dynamic intelligent environment. This paper proposes a framework that provides user-customized dynamic intelligent environments in smart spaces. In the existing research that provides user-customized intelligent services, users' interests are only explicitly analyzed, and smart spaces are not considered. Implicit interest analysis can suggest a service that may be of interest to users rather than explicit interest analysis, but it requires higher performance than explicit interest analysis. Smart spaces can obtain useful information by interacting with information in the space. The framework proposed in the study uses a proximity-based social network of things to fit into a smart space. In addition, the implicit interest analysis provides intelligent information for smart spaces using the social media information and spatial information objects. In addition, we propose a method to prevent performance degradation while maintaining accuracy in consideration of the characteristics of the smart space.

The purpose of this study is to examine problems and status quo of the smart media addiction prevention system and to develop convergence policies to improve those systems. Based on the literature review, notable results are as following; Since current facilities including Internet Addiction Prevention Center, Korea Youth Counselling and Welfare Institute, and I Will Center, tend to focus on restricting use of smart media, efforts from various ministries have not worked properly. Therefore, there needs to be more specified and customized services based on regions and ages. Following the precedent set by advanced countries, this study suggest alternative policies to help solving the problem including recommending responsible use of social media through education rather than regulations only, encouraging family participation and intervention, expanding harmful environment block system, and establishing a partnership between local government and private organizations under central government's control. Since smart media addiction is emerging concern, further researches will be needed for developing the Korean standard for prevention policy.
