The purpose of this study is to explore how South Korean TV news programs represent the image of North Korean defector through analyzing South Korean TV news contents portraying North Korean defector. In order to conduct this research, the study analyzes the main subjects of the South Korean TV news contents, the image of characters on the TV news contents, and frames which the TV news contents mainly used. According to the results of this study, the TV news programs represent the positive image of South Korean government whereas they criticize North Korean government while representing North Korean defector issues. However, the TV news programs showed no interest in real problems which the North Korean defectors are experiencing. Further, the findings of this study are very similar to the results of previous studies that were analyzing the representation of news media about minority groups including North Korean defectors. Most studies analyzing how news media represent minority groups show that the groups have been identified not by their own opinions and relations but predominant culture and lifestyles in the society, and they are also represented not by their own voice but predominant perspectives of the society.

Recently, media diplomacy takes on a substantial role in information war not only in setting global agenda but also in delivering their favored views and frames. Focusing on its crucial impact, this study attempts to investigate empirically the relationship between national prestigious media's news coverage and it's own foreign policy particularly about the 2011 Libya conflict. The total of 530 news articles in such 24 hour English news channels as BBC World, Cnn International, Russia Today, France24, Al Jazeera English and Deusche Welle were analyzed for this study. The analyses reveal that Libya coverages of those news channels are entirely constructed in the context of the foreign policy. To put it concretely, there was the undeniable level of differences in terms of quoting relevant sources, viewpoints, attitudes and frames for the pursuit of media diplomacy helped by high quality journalism. The authors argue in this regard that protecting information sovereignty should be urgently discussed even in the time of digital revolution. To launch 24-hour English news channel like 'Korea 24' would be a possible strategy for influencing global agenda and perspective in way of supporting national interests.

The purpose of this study is to explain and predict trends the AI development process based on AI technology patents (total) and AI reporting frames in major newspapers. To that end, a summary of South Korean and U.S. technology patents filed over the past nine years and the AI (Artificial Intelligence) news text of major domestic newspapers were analyzed. In this study, Topic Modeling and Time Series Return Analysis using Big Data were used, and additional network agenda correlation and regression analysis techniques were used. First, the results of this study were confirmed in the order of artificial intelligence and algorithm 5G (hot AI technology) in the AI technical patent summary, and in the news report, AI industrial application and data analysis market application were confirmed in the order, indicating the trend of reporting on AI's social culture. Second, as a result of the time series regression analysis, the social and cultural use of AI and the start of industrial application were derived from the rising trend topics. The downward trend was centered on system and hardware technology. Third, QAP analysis using correlation and regression relationship showed a high correlation between AI technology patents and news reporting frames. Through this, AI technology patents and news reporting frames have tended to be socially constructed by the determinants of media discourse in AI development.

This study examines how television news constructed an issue of social conflict between nationwide and local broadcasting. Especially, this study focused on new ariport of east-south region in Korea. To do this, this study conducted frame analysis on KBS, MBC, SBS main news including national and local ones, broadcasted from 1 January, 2011 to 15 April, 2011. In addition, frame analysis was divided into two aspects, formal and substance. As a result, the findings are as follow: First, in formal aspect both national and local broadcastings are dealing with episode style news frames, while subject style is just 7.5%. Second, in substance aspect, 6 categories are founded: site decision frame, competition and conflict frame, economic frame, rescission and response frame, government countermeasure and alternative frame, etc frame. In conclusion, national and local broadcasting television news have different perspective each other on defining an issues of social conflict like east-south new airport.

This study analyzed the news media coverage of QRcodes in Korea over a 16-year period (2008 to 2023). A total of 13,335 articles were extracted from the Korea Press Foundation's BigKinds. A quantitative and content analysis was conducted on the news frames. The results indicated that the quantity of news coverage has increased. The greatest quantity of news coverage was observed in 2020, and the most frequently discussed topic in the news was 'IT_Science'. The results of the keyword analysis indicated that the primary words were 'QRcode', 'smartphone', 'service', 'application', and 'payment'. The news media primarily focused on the QRcode's ability to provide instant access and recognition technology. This study demonstrates that advanced information and communication technologies and the increased prevalence of mobile devices have led to a rise in the utilization of QRcodes. Furthermore, QRcodes have become a significant information media in contemporary society.

For the efficient searching and browsing of digital video, it is essential to extract the internal structure of the video contents. As an example, a news video consists of several sections such as politics, economics, sports and others, and also each section consists of individual topics. With this information in hand, users can ore easily access the required video frames. This paper addresses the problem of automatic shot boundary detection and selection of representative frames (R-frames), which are the essential step in recognizing the internal structure of video contents. In the shot boundary detection, a new algorithm that have dual detectors which are designed specifically for the abrupt boundaries (cuts) and gradually changing bounaries respectively is proposed. Compared to the existing 미algorithms that mostly have tried to detect both types by a single mechanism, the proposed algorithm is proved to be more robust and accurate. Also in the problem of R-frame selection, simple mechanical approaches such as selecting one frame every other second have been adopted. However this approach often selects too many R-frames in static short, while drops important frames in dynamic shots. To improve the selection mechanism, a new R-frame selection algorithm that uses motion information extracted from pixel difference is proposed.

This Paper suggests a new feature for shot detection, using the proposed robust feature from the DC image constructed by DCT DC coefficients in the MPEG video stream, and proposes the characterizing value that reflects the characteristic of kind of video (movie, drama, news, music video etc.). The key frames are pulled out from many frames by using the local minima and maxima of differential of the value. After original frame(not do image) are reconstructed for key frame, indexing process is performed through computing parameters. Key frames that are similar to user's query image are retrieved through computing parameters. It is proved that the proposed methods are better than conventional method from experiments. The retrieval accuracy rate is so high in experiments.

This study aims to analyze how the Korean liberal and conservative newspapers cover the filibuster for blocking the passage of the anti-terrorism act for the protection of citizens and public security by the main opposition party. For the comparative analysis of the Korean liberal and conservative newspapers, this study analyzes how the newspapers used news frame, news source, key word, and news theme. To analyze the effects on news coverage of the newspapers' ideological orientation, this study selects six newspapers: Hankyoreh Shinmun, Kyunghyang Shinmun, Ohmynews from liberal newspapers and Chosun Ilbo, Donga Ilbo, Joongang Ilbo from conservative newspapers. According to research findings, the liberal and conservative newspapers show clear distinction while using news frames when the newspapers cover the filibuster. The liberal newspapers cover the filibuster as a positive political action while the conservative newspapers cover the filibuster as a negative political action. In addition, as key word, "disturbance" is mentioned most by the conservative newspapers while "poisonous clauses" is used most by the liberal newspapers. As a result, this study shows that newspapers are influenced by ideological orientations while covering political issues.
