As 49% of the world's population uses social media platforms, communication and content sharing within social media are becoming more active than ever. In this environmental base, the one-person media market grew rapidly and formed public opinion, creating a new trend called sell-sumer. This study defined new types of influencers by product category by analyzing the subject concentration of the commercial/non-commercial keywords of influencers and the impact of the ratio of commercial postings on sales. It is hoped that influencers working within social media will be helpful to new sales strategies that are transformed into sell-sumers. The method of this study classifies influencers' commercial/non-commercial posts using Python, performs text mining using KoNLPy, and calculates similarity between FastText-based words. As a result, it has been confirmed that the higher the keyword theme concentration of the influencer's commercial posting, the higher the sales. In addition, it was confirmed through the cluster analysis that the influencer types for each product category were classified into four types and that there was a significant difference between groups according to sales. In other words, the implications of this study may suggest empirical solutions of social media sales strategies for influencers working on social media and marketers who want to use them as marketing tools.

The present study began from the criticism that the discussions related to the existing digital media have focused on the technical productivity and effectiveness to focus on the positive perspective. Therefore, this study will concretely confirm the dangers that may be caused by digital media and confirm the overall risk perception for digital media such as the user's opinions for risk evaluations and risk management for such dangers. As a result of making the digital convergence media, the smart phone, as the detail study subject, the 17 risk types including the 'risks of financial dimensions, risks of social-cultural dimensions, risks of individual dimensions and risks of pathological dimensions' were classified. Furthermore, the users appeared to highly evaluate the seriousness and possibilities of risks as a result of analyzing the risk-factor per each risk type(risk magnitude ${\times}$ development possibility). Next, it appeared that the users did not have high degree of reliability for the government in the aspects of countermeasures and prevention of risks and appeared to highly evaluate their expectation and liability for their individual roles. If the seriousness and development possibilities, the evaluations for liability, preventative measures and post-management methods for the risks of smart phones can be thoroughly analyzed and applied, it will be able to expand them as significant political countermeasures that can reduce the risks of other digital media in the future.

Recently, media's attention to tourism is enhanced, and the proportion of tourism related content is increasing. Hence, the present study performed a content analysis of the travel news stories in major Korean newspapers to figure out the current state of travel journalism. A rotation sampling method was employed, and 53 days in 2013 were selected. Main coding categories were type, theme, and writer of the news stories and the degree of promotional information in the news stories. Differences among newspapers and the degree of inclusion of the promotional information according to news types and themes were analyzed. Analyses revealed the differences among newspapers and the degree of inclusion of promotional information was different according to the news types and themes. On the basis of the findings, problems of the travel journalism were identified, and possible measures to solve the problems were discussed.

In Korea, video-based news broadcasters are primarily classified into terrestrial broadcasters, general programming cable broadcasters and YouTube broadcasters. Recently, news broadcasters get subjective while targeting the desired specific audience. This violates normative expectations of impartiality and neutrality on journalism from its audience. This phenomenon may have a negative impact on audience perceptions of issues. This study examined whether broadcast news reporting conveys emotions and if so, how news broadcasters differ according to emotion type. Emotion types were classified into neutrality, happiness, sadness and anger using a convolutional neural network which is a class of deep neural networks. Results showed that news anchors or reporters tend to express their emotions during TV broadcasts regardless of broadcast systems. This study provides the first quantative investigation of emotions in broadcasting news. In addition, this study is the first deep learning-based approach to emotion analysis of broadcasting news.

This study introduced the concept of 'Media-content repertoire', which indicates the set of favorite media-content combinations of media users and extracted five media user types based on those combinations. We used the range of media(i.e., smartphone, tablet, PC, and TV) and entertainment content(i.e., movie, broadcasting, music, and game) for the analysis. Also, we investigated the differences between those types including demographic variables, individual characteristics, and content buying behavior and we found that statistically significant differences exist among them. Those include 'non-user'(i.e., lower level of media use), 'screen user'(i.e., 50s, TV-centered media use), 'variety seeker'(i.e., 20s. heavy public transport user), 'selective focus'(i.e., 20,30s, movie&broadcasting-centered media use), and 'heavy user'(i.e., high level of media use and consumption). The results provide both academic implications(e.g., extension of media repertoire concept) and practical implications(e.g., direction to the target marketing for each user type).

The perception type of this study were divided into three types in all through Q-methodology. Above all, this study is to investigate two points us. Points of this study ; First, how the type of the perception is divided on the subjectivity about Media Fortune-contents in Digital Age? Second, what is a trait of character in same or different quality within these types? The result reveal five type that divided '1 : Scientific Appeal Type ; N=10', '2 : Value-depended Type ; N=7', '3 : Positive Preference Type ; N=3'. It found that is very different type all over.

This study briefly examines the regulation of market-dominating enterprises in terms of market definition, judgement about market dominance, judgement about abuse of market-dominant position, and types of abuse of market-dominant position. This study explores Korea Fair Trade Commission's judgemental cases regarding the prohibition of abuse of market-dominant positions under 'Korea Monopoly Regulation and Fair Trade Act' and focuses on 21 cases related with Korean media industry. Based on this case analysis and literature review, this study derives major issues, problems, and possible alternatives in the regulation of market-dominating enterprises in media markets. And this study suggests implications about monopoly regulation and fair competition policy of Korean media industry.

콘텐츠의 기하급수적인 증가와 다양한 서비스 확산에 따라 추천 서비스에 대한 연구는 날로 증가하고 있다. 특히, SNC 이용의 증가는 콘텐츠의 생산과 소비에 대한 주체를 새로운 관점에서 파악 할 수 있는 유용한 정보원이 되고 있다. 따라서 본 논문에서는 SNC에서의 사용자에 대한 속성 데이터와 활동 데이터를 바탕으로 정보 처리활동 기반의 속성 요소를 도출하고, 이를 바탕으로 개인화 서비스를 제공하기 위한 사용자 유형 모델링 방안을 제안하고자 한다. 사용자 유형 모델링은 사용자 속성 요소 정의와 이들 사이의 관계로 구성된다.

최근에 웹을 이용한 원격교육에 대한 않은 학습 방법들이 제시되고 있으며, 단순히 학습만을 고려한 방법부터 실시간으로 원격시험을 치르는 방법까지 다양하다 웹 기반의 학습에서 많이 적용되는 방법이 문제를 통한 학습이며, 기존의 학습들은 학습자가 개인 수준에 안는 문제 난이도를 직접 선택하거나, 문제를 동적으로 추출하여 학습하는 방식이다. 그러나 이 방법들은 단순히 출제되는 문제 자체의 차별성을 기반으로 하므로 학습자의 능력별 학습이 이루어지기 어려운 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하기 위하여, 개인의 문제유형별 약점정보를 기반으로 유형별 추출되는 문제에 난이도를 두어 개인별 학습 능력을 정확히 평가한다. 그리고 다음 단계의 학습에서 개인별 학습정보를 충분히 반영하여 문제들을 출제하므로 학습자의 학습효과를 높일 수 있다. 따라서 이 시스템은 문제유형과 문제난이도에 대한 개인의 정보를 반복적으로 적용하여 학습할 수 있으므로, 더욱 효과적인 원격학습을 제공할 수 있다.
