This study aims to find the factors of Internet overdependence in adults, through the decision tree analysis model, which is a data mining method using National Information Society Agency's raw data from the survey on Internet overdependence in 2016. As a result of the decision tree analysis, a total 16 nodes of Internet overdependence risk groups were identified. The main predicated variables were the amount of time spent per smart media usage in weekdays; amount of time spent per smart media usage in weekends; experiences of purchasing cash items; percentage of using smart media for leisure; negative personality; percentage of using smart media for information search and utilization; and awareness on good functions of the Internet, all of which in order had greater impact on the risk groups. Users in the highest risk node spent the smart media for more than 5 minutes per use and less than 5~10 minutes in weekdays, had experiences of cash item purchase, and had lower level of awareness on the good functions of the Internet. The analysis led to the following recommendations: First, even a short-time use has higher chances of causing Internet overdependence, and therefore, guidelines need to be developed based on research on the usage behavior rather than the usage time. Second, self-regulation is required because factors that affect overindulgence in games, such as the cash items, increase Internet overdependence. Third, using the Internet for leisure causes higher risk of overdependence and therefore, other means of leisure should be recommended.

In this paper, on-demand service streaming protocol for user-created contents in digital cable broadcasting environment is considered. In order to provide variety media contents service like UCC in digital cable broadcasting environment, the same service model as RVOD(Real Video on Demand) is required and the different interface for each broadcasting platform is needed in a current OCAP environment. Using return path based RTP, we separate existing VOD stream band into broadcasting and VOD stream band. In order to broaden On-demand service, consistent expansion of the infrastructure same as live broadcasting system is inefficient in the digital cable broadcasting environment. Using existing network protocol, the service which is insensitive to the infrastructure for VOD service becomes possible. Therefore we considered the analysis of the class of download available structure in the Set-Top-Box for RTP(Real-time Transport Protocol) and designing the decoding available streaming server for UCC transcoding and transmission in the receiver. Designing a efficient VOD service and system under the broadcasting environment gives a expansion of On-Demand service and more chance to upload and utilization of contents.

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.

The results of the survey on water utilization status, the wasted water factor, the awareness, and the education and promotional activities of water saving in Daejeon City are as follows: The percentage of using tap valve with a closure was 66% when showering. 74% of water was used with closing the tap valve when washing faces with no water needed, it was still considered that there existed a wasting water. The most wasting reasons of water were found to be shower, bath, and laundry in order. In the awareness of practicing tap water saving, 9.1% of respondents acted actively, 53.4% of them were trying to practice it, and more than 63% had a positive awareness. In the contents of practicing saving water, locking water when soaping while showering, non-laundry of small quantity, and using cups when brushing teeth were top priorities. About 50% of the reasons for saving water was to practice purely saving water, when saving for economic help was excluded. The level of water saving awareness was not high when considering that the ratio of usage without water saving equipment and installation, and using method was relatively high when moving in. In order to make usage of water saving equipment more common, it was deemed necessary to provide information on the purchase of water saving equipment and to promote and educate the efficiency of saving of related products. More than about 90% of the respondents responded that water saving education or promotional activities had an effect of improving water saving awareness. The most effective method of education and promotional activities was found to be 40.4% by mass media activities, and 21.7% by promotions through mobile devices.

Most current literature on knowledge and technology transfer(Appropriability Model, Dissemination Model, and Knowledge Utilization Model), describe the process of transfer in details, but has limitation in terms of their application in contemporary high-tech industries since most studies have not provided plausible explanation on levels and factors affecting transfer of knowledge and/or technology. To overcome these limitations, the four levels of knowledge and technology transfer are suggested: Knowledge and Technology Creation(Level I), Sharing(Level II), Implementation(Level III), and Commercialization(Level IV). Comprehensive literature identifies sixteen variables affecting the process and results of knowledge and technology transfer. The survey results show four key factors in knowledge and technology transfer: Communication, Distance, Equivocality, and Motivation, Communication refers to the degree to which a medium is able to efficiently and accurately conveys task-relevant information and media while distance involves both physical and cultural proximity. Equivocality refers to the degree of concreteness of knowledge and technology to be transferred while motivation involves incentives for and the recognition of the importance of knowledge and technology transfer activities. Further analysis shows that there are four distinctive clusters and they show very contrasting characteristics in terms of four key factors. The careful mapping of the four clusters on the four key factors show very informative knowledge and technology transfer patterns, the Knowledge and Technology Transfer Grid. Finally, actions to increase communication interactivity and motivation, and to reduce cultural distance and equivocality are suggested.

This study is to verify the mediating effect of self-esteem on the effect of the elderly's smart device use on life satisfaction. To this end, secondary data analysis was conducted using the Korea Media Panel Survey conducted by the Information and Communication Policy Institute in 2021. The responses of 3,211 people in their 60s or older who are the subjects of this study were utilized. For analysis, descriptive statistics, correlation, and multiple regression analysis were performed using SPSS, and the Sobel test was conducted to verify mediating effects. As a result, smart device utilization averaged 2.13 points out of 5, indicating that the actual utilization level was less than half. The use of smart devices, an independent variable, had a positive effect on the dependent variable, life satisfaction. Self-esteem, which is a parameter, has been verified as a partial mediating effect in that smart device use affects life satisfaction. Based on the results of this study, various policy and practical measures were proposed to increase the smart device utilization rate of the elderly in Korea, improve self-esteem and life satisfaction, so that they can spend a happy old age.

The objective of this study is to investigate the current usage and Satisfaction Levels of modern literature services provided by the National Library of Korea, and explore the strategies to promote the use of the modern literature service. The result show that the usage rate of users for the modern literature service is very low, and the Satisfaction Level of the experienced users are found to be normal. Therefore, in order to increase the utilization rate and the Satisfaction Level, first, it is required for active promotion of current modern literature services. Second, the public relations of exhibitions and viewing information are provided direct access to users of the modern literary materials, so various types of exhibitions and events are necessary. Third, although respondents said that library homepage, portal site, and SNS are effective public relations methods, in the case of less-educated and seniors, they prefer public relations through offline media. Therefore, deeper theoretical considerations are necessary in order to select affordable public relations media.
