As the use of mobile data increases, the proportion of video content is increasing steeply. In order to solve problems that arise when mobile users receive data from geographically remote cloud servers, methods of caching data in advance to edge servers geographically close to the users are attracting lots of attention. In this paper, we present a caching policy that stores data on Small Cell Base Station(SBS) to effectively provide content files to mobile users by applying a delayed offloading scheme in a cellular network. The goal of the proposed policy is to minimize the size of data transmitted from Macro Base Station(MBS) because the delayed offloading scheme requires more cost than when downloaded from MBS than from SBS. The caching policy is proposed to determine the size of content file and which content file to be cached to SBS using the probability of mobile users' paths and the popularity of content files, and to replace content files in consideration of the overlapping coverage of SBS. In addition, through performance evaluation, it has been proven that the proposed policy reduces the size of data downloaded from MBS compared to other algorithms.

The aim of this study was to develop a policy information mentoring management model through which professional information, knowledge, and ideas can be shared and consulted. To this end, we analyzed domestic and international related literature, case studies of domestic and international mentoring programs, and expert advice from the policy consumers and current policy mentors in the field of policy information. In this research, components of a policy information mentoring management model have been proposed by separating them into human and content components. Mentor-mentee coordination, and supervisors are proposed as human components. Policy mentoring subject areas, programs, and detailed activities are proposed as content components.

Gendered innovation in Science, Technology and Innovation, which seeks better science for both men and women by integrating sex and gender analysis, has become an important issue in the entire process of STI, as initiated by the European Commission, Canadian Institutes of Health Research in Canada and the National Institutes of Health in the United States. Korea has also attempted to reflect gendered innovations in Science and Technology as a critical factor in the 3rd and 4th National Plan, followed by the Act on Women Scientists and Engineers (2002). Against this background, the aim of this study is to prioritize the policy instruments regarding gendered innovation in Research and Development. Through the Focus Group Interview (FGI) and the Analytic Hierarchy Process (AHP), this study attempts to set the priority among selected criteria, various types of policy instruments, and the applied research development area. As a result, this study shows the preparation of the relevant legal and institutional mechanisms for the full introduction of gendered innovation in S&T, and the importance of various policy instruments for S&T innovation in the fields of planning, budgeting, managing national R&D projects, evaluating and impact assessment, etc., being derived in a systematic way to ensure their effectiveness.

This paper attempted a content analysis on the S&T comprehensive plans in Korea focusing on five-year plans. They include twelve plans from the 1st five-year plan for technological promotion($1962{\sim}1966$) to S&T basic plan in participatory government($2003{\sim}2007$). The result of content analysis on such plans was explained according to policy environments, formative system, policy goals, policy scopes, and policy subjects. In the case of policy subjects, this paper reconstructed nine policy categories such as national strategic technology development, S&T investment, S&T manpower, basic science research, private technology development, international S&T cooperation, regional S&T innovation, S&T infrastructure, and S&T culture. In conclusion, this paper proposed future directions for the making of S&T comprehensive plans in Korea.

Content Centric Network(CCN) with architecture that is completely different from traditional host-based networks has emerged to address problems such as the explosion of traffic load in the current network. Research on cache replacement policies is very active to improve the performance of CCN with the characteristics that all routers cache on the network. Therefore, this paper proposes a cache replacement policy suitable for situations in which popularity is constantly changing, taking into account the actual network situation. In order to evaluate the performance of the proposed algorithm, we experimented in an environment where the popularity of content is constantly changing, and confirmed that we are superior to the existing replacement policy through comparing hit rates and analyzing server load.

This article puts forward the opinion of a policy expert, who had been involved in Korea's science and technology policy for 30 years, about technology policy for SMEs. This article first explains why technology policies for SMEs are needed, and from what point of view. The next section looks at the current problems facing Korean SMEs, followed by the introduction of past and current polices to support SMEs. The comparison between current issues facing SMEs and past and current policies leads to lessons that can be learned. There are four lessons for the policy itself and three for the implementation of these policies. As for policy, the first four are about stages of development, concentration, R&D and diffusion, and policy mix. The latter three are policymakers, institutional building, and cooperation between ministries. This article makesfour suggestions for future policy: the importance of startups' culture, cooperation with others, infrastructure to reduce uncertainty, and policy monitoring and evaluation.

In order to overcome the limits of domestic image content market, entering the global market is inevitable and expanding our market volume in foreign market as in domestic market is an important factor that determines the future of Korea image content industry. Suggestions and discussions on policy for investments on domestic image content should be carried out to resolve such situation. Specially, the reason why cooperative system of central government and local government is in dire need is because cultural content industry support measures of central government is unsatisfactory and local government is not adequate enough to respond to the global environment because investment resources of small and medium enterprises in cultural content is insufficient. This paper intends to study cases of policy promoted by domestic local government and support cases of foreign countries when domestic image content industry is expanding into the global market, and to search for solutions from integrated functional perspective of central government and local government for international co-production environment. This study suggests the necessity of political connection in terms of central government strengthening assistance policy on dispersed policy of local government who operates 11 cultural industry promotion districts throughout the country. First, this study suggests the possibility of expanded international co-production by central government and local government through investment(fund).

To counter-attack against piracy, the movie industry is continuously developing new technologies for the protection of intellectual properties, only to find them instantly useless especially in the digital age. This study shifts the focus from technology to customer behavior, and analyzes customer behaviors vis-à-vis piracy using economic models. The theoretical model of optimal holdback strategy under the threat of piracy was derived and the result shows that holdback can be used as a tool not only for hedging the loss due to piracy, but also for reducing piracy. Based on the theoretical model, we suggested proper holdback strategy for each type of movie piracy.

Recently K-POP's popularity and the success story of 'Psy' suggests that Korean Culture can get the possibility of entry into the global major market. Increasing the purchasing power of global contents distribution also shows that the delivery of cultural content can be a big business model to create economic benefits. However, for sustainable diffusion of Korean culture, we need efforts to expand the business scope to the global market like the establishment of global distribution platform. In this study, we investigated key factors for activating the global content distribution and then analyzed priority of importance of the factors to be utilized the strategic alternatives using AHP method. To ensure the reliability of the study, experts (30patients) who worked more than 10 years of relevant work were included as population of the questionnaire. The results of analysis, the relative importance of content aspects were higher than technical aspects and policy aspects. In the analysis of the importance of the second layer factors, the business models of policy aspects were analyzed as a factor of top priority, then high-quality content production was selected as an important factor of the next higher ranks.
