This study analysed the complicated introduction process of IPTV in Korea, based on the rent seeking theory which is one of an useful economic theory for explaining the dynamic interaction between government and entrepreneurs. Rent seeking theory describes the possibility of lobbying for economic regulations or regulatory capture which refers to collusion between firms and the government agencies assigned to regulate them. The introduction of IPTV(Internet Protocol TV) in Korea was the most controversial policy issue since the beginning of new media business of cable TV in 1995. In addition to the ordinary conflict between the old and new entrepreneurs, IPTV caused the bureaucratic conflicts between the Ministry of Information and Communication and the Korean Broadcasting Commission (Two regulation agencies were merged into KCC(Korean Communications Commission) in 2008). Through the process all related policy players, including the government, pursued their own rent, and it caused vicious circle of continuous rent seeking and mutual distrust among players. Finally, all-directional lobby of pre-IPTV companies brought about the successful entrance to IPTV market and the enactment of IPTV special law which includes deregulation compared to the existing Broadcast Act. Considering the convergence trend of media related laws it means going against the times. Until now, the conflict phenomena occurring in broadcast industry were mostly explained based on the sociological conflict theory. However, the result of this study shows the usefulness and necessity of rent seeking theory because it gives an economic explanation of conflict behavior.

As electronic marketplaces grow and a large number of consumers exchange their opinions on products and services on the Internet, many studies have been conducted in the area of online consumer reviews. This paper analyzes the research trend of the online consumer reviews by investigating those studies in an attempt to provide future research directions. Many researchers have focused on the effects of online reviews on consumer behaviors as well as the usefulness of the online reviews. In particular, review contents, characteristics of reviewers/consumers and features of products/services have been identified as influencing factors on the effects of the online consumer reviews. For the review contents, the number and the volume of the contents have increasing effects on the online reviews, while the direction (positive vs. negative) of the contents has resulted in conflicting effects of the review. The reputation and trustfulness of reviewers, consumers' prior knowledge on the products, consumers' product involvement, and types of the products were investigated as these factors influence the effectiveness of the online consumer reviews. Social media (such as Facebook and Twitter) nowadays play an important role to disseminate online reviews among consumers. Thus, it is necessary to study how social media influence the effects of online reviews on consumers. Since some firms abuse the online reviews for their own sakes, we recognize the necessity for empirical studies on the side effects of the online reviews.

This study investigated the perceptions of librarians about Podcast and YouTube services in libraries. The study was designed by applying the Extended Technology Acceptance Model. Librarian's personal, organizational, and social awareness of library Podcast or YouTube services and the degree of understanding of users and their needs on services were mediated by perceived usefulness or ease of services= and influenced to having intentions and providing the services. First, we investigated the types of Podcast and YouTueb services provided by 39 libraries in Korea. Also, we collected data using an online survey method from 181 librarians and conducted hierarchical multiple regression analysis. Findings showed that libraries are using Podcast and YouTube appropriately considering features and functions of media, mainly for library event information/promotion, library programs, book recommendations, and author (librarian) lectures or interviews. Organizational or social awareness of librarians, i.e., library educational support, human resource supports, librarian recognition, job-related features, and understanding of user perceptions and needs, influenced the intention to provide library services. Also, there was a difference in perceived usefulness and ease of services between librarians who provided Podcast and YouTube services and those who did not. We expect that findings could be used as references to understand and support various aspects of librarians in charge of developing and providing Podcast or YouTube services in libraries.

Objective : The purpose of this study is to examine the effects of therapeutic interventions on upper extremity function of children with cerebral palsy using systematic review methods and to suggest intervention trends in Korea. Methods : The subjects of the study were the researches published in the Korean Journal since 2008. Total 12 studies were selected through Korean research database engine such as DBpia, Scholar, KSDC, KISS and RISS for the systematic review. Key words were 'cerebral palsy', 'upper extremity function' and 'hand function'. The results of this study were analyzed by qualitative level and methodological quality level of evidence, and the results of each study were analyzed according to the PICO approach, that is Patient, Intervention, Comparison and Outcome. Results : For the level of evidence, Grade IV and V were most frequent. In terms of methodological quality, majority of the studies showed 'Fair' level. The subjects were the children with hemiplegia, and Single-subjects designs and case studies were frequent experimental design. Constraint-induced movement therapy (CIMT) was most frequently conducted among the intervention studies, and Jebsen-Taylor Hand Function Test was most frequently used evaluation tool. Eleven studies showed that the upper limb functions were significantly improved or were positively effective. Conclusion : Various intervention methods have been implemented to improve the upper limb functions of children with cerebral palsy. In the future, studies on intervention methods based on the type of paralysis and studies with high quality of evidence should be conducted in Korea.

The purpose of this study is to recognize kindergarten teachers' experiences of child violence for identifying the site's needs for the implementation of preventive education in early childhood and to provide basic data on child violence. To this end, nine teachers were interviewed in-depth. From the study results, first, child violence-related child behavior, which usually occurs in kindergartens, includes physical assault, aggression, verbal violence, threats and threats, and bullying. Second, teachers usually use direct intervention laws in cases of child violence, but were finding it difficult to intervene properly with many tasks or high teacher-to-child ratios. Teachers recognized the need for lower teacher-to-child ratios and placement of each class burden. Third, teachers were aware of the need for prevention education for child violence targeting infants, and instigated the following appropriate interactions immediately after problem behavior occurred: large group activities, specific multimedia education data and parent education. Fourth, teachers are concerned about the possibility of problem behavior being learned and imitated through education in the implementation of prevention education for children's violence. Therefore, this study proposed the need to develop various teaching methods that could be applied to infant education sites, focusing on the types of child violence-related problem behaviors that occur in kindergartens.

Despite empirical research that the response to human risk is significantly influenced affective factors, the role of affective factors has been unexplored in information privacy research. This study aims to explore the privacy behaviors of location-based service (LBS) users from an affective point of view. Specifically, the study explored the relationship between three types of privacy threats (collection, hacking, secondary use), two affects (worry, anger), and a coping behavior (continuous use intentions). The structured survey was conducted with 552 users. In order to analyze the effect of the combination of perception of particular privacy threats and particular affects on the intention of continuous use, association rules, one of the data mining techniques, was employed. As a result, there was a difference in the intention to use according to the combination of the perception of risk and affect responses, and the most significant influence on the intention is when the second use of personal information was combined with anger. This study has significant theoretical contribution in that it includes affective factors in the research of information privacy users, complementing the biases of existing cognition-oriented approaches and providing a comprehensive understanding of privacy response behavior.
