This study explores the news frames on the U. S. beef imports and candlelight vigils covered by the two national dailies such as ChosunIlbo and the Hankyoreh Shinmun; the KwangwonIlbo, a local daily. The news frames extracted based on the models of Iyengar(1987), Semetko & Valkenburg(2000) and other researchers are attribution of responsibility, economic sequences, protest against the authorities, national health and governmental public relations and so on. The result shows that the news reports are consisted of the straight news(75.9%), feature stories(11.7%) and editorials(6.3%). More specifically, there is a comparatively hight ratio of editorials(11.0%) for the ChosunIlbo, feature stories(20.9%) for the Hankyoreh, and the straight news(89.7%) for the KwangwonIlbo. In terms of the news frames stressed by the three dailies, the ChosunIlbo focuses and stresses on the national health(17.8%) and the attribution of responsibilities(10.6%). However, the Hankyoreh have a tendency to stress on the protest against the authorities(31.3%) and attribution of responsibilities(38.4%); the KwangwonIlbo, focuses on the protest against the authorities(38.4%) and the economic sequences(17.9%). Finally, in the case of the main characteristics of the dailies, the governmental public relations frame is found only on the ChosunIlbo that has a comparatively high ratio; the Hankyoreh also has a high ratio of the feature stories on the U. S. beef imports. Even thought the KwangwonIlbo has a high ratio of the economic sequence frame, the ratio of opinion pages, such as editorial and columns, the local newspaper has not spoken up for the potential economic crisis of the local Kwangwon province beef industry, mainly caused by the U. S. import beef.

Recently many informations are transmitted ,md stored as video data, and they are on the rapid increase because of popularization of high performance computer and internet. In this paper, to retrieve video data, shots are found through analysis of video stream and the method of detection of key frame is studied. Finally users can retrieve the video efficiently. This Paper suggests a new feature that is robust to object movement in a shot and is not sensitive to change of color in boundary detection of shots, 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 de image) are reconstructed for key frame, indexing process is performed through computing parameters. Key frames that arc similar to user's query image arc 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.

his study classified the development process of artificial intelligence (AI) speakers through analysis of the news text of artificial intelligence (AI) speakers shown in traditional news reports, and identified the characteristics of each product by period. The theoretical background used in the analysis are news frames and topic frames. As analysis methods, topic modeling and semantic network analysis using the LDA method were used. The research method was a content analysis method. From 2014 to 2019, 2710 news related to AI speakers were first collected, and secondly, topic frames were analyzed using Nodexl algorithm. The result of this study is that, first, the trend of topic frames by AI speaker provider type was different according to the characteristics of the four operators (communication service provider, online platform, OS provider, and IT device manufacturer). Specifically, online platform operators (Google, Naver, Amazon, Kakao) appeared as a frame that uses AI speakers as'search or input devices'. On the other hand, telecommunications operators (SKT, KT) showed prominent frames for IPTV, which is the parent company's flagship business, and 'auxiliary device' of the telecommunication business. Furthermore, the frame of "personalization of products and voice service" was remarkable for OS operators (MS, Apple), and the frame for IT device manufacturers (Samsung) was "Internet of Things (IoT) Integrated Intelligence System". The econd, result id that the trend of the topic frame by AI speaker development period (by year) showed a tendency to develop around AI technology in the first phase (2014-2016), and in the second phase (2017-2018), the social relationship between AI technology and users It was related to interaction, and in the third phase (2019), there was a trend of shifting from AI technology-centered to user-centered. As a result of QAP analysis, it was found that news frames by business operator and development period in AI speaker development are socially constituted by determinants of media discourse. The implication of this study was that the evolution of AI speakers was found by the characteristics of the parent company and the process of co-evolution due to interactions between users by business operator and development period. The implications of this study are that the results of this study are important indicators for predicting the future prospects of AI speakers and presenting directions accordingly.

The main purpose of this study is based on the comparative analysis over news framing of the family headship(Hoju) abolition in Korean society. This study examined the newspaper articles involving the Hoju abolition, which had been printed on the three major dailies, Chosun, Kukmin, Hankyoreh through February of 1990 to July of 2005. First, the news articles were analyzed and classified on the basis of their lengths, news types, main characters, news framing and systematic framing. Second, the articles that this study looked into were divided into the five major periods when the issue of the Hoju abolition in Korean society surfaced as a main social agenda to be discussed. Third, the main differences between the noticeable frame and unnoticeable frame in each period were analyzed through the three different perspectives which can also can be sub-divided into the six different attributes. This study found that the Hoju abolition as an attribute had developed into political, legal and social fields. The analysis of the research shows that the articles related to the patriarchy abolition showed more dominant frame which reflected the social change or the general tendency of the times. However, the analysis indicates that the articles in the level of an attribute included more dominant frame which mirrored a male chauvinism society. It also points out that the articles contained more dominant frame which was be used as a standard to find out the readers' political inclination. The articles also showed the dominant frame which included the revision and legal process of family laws before presidential or general election campaigns. The study also found that there were major differences among the three dailies. First of all, Chosun, regarded the Hoju as a custom by stressing that 'it is necessary to keep Hoju system to intensify the role and crisis of family if the Hoju will be abolished'. However, Hankyoreh recognized the issue as an important one to improve feminism and female rights by maintaining that 'it is the time to balance the inequality out between men and women with the abolition of patriarchy'. Finally, Kukmin treated the issue as an first step to acknowledge the dignity of females by emphasizing that 'a revision of the law is essential to accept the changing ethics of the times'.

By comparing and analyzing the September 11 terror attack news reports on the daily papers in the U.S., Korea, and China, this research found that national ideology and international relationship concerned have affected news report frames about international dispute matters. Both quantitative and qualitative researches identify differences in news framing. For example, after the September 11 terror attack, the most pages of the USs The New York Times and Korean Chosunilbo were covered with related articles(382 and 192 reports, respectively), whereas Chinese Inminilbo cur down to only 32 reports about the issue. Also in content, both The New York Times and Chosunilbo viewed the September 11 terror attack as evil acts which threatened world peace and justified military action against Afghanistan as inevitable revenge and justice for such evil acts, in the point of the USs official view. However, Inminilbo gave out news only based on facts in a neutral viewpoint. Moreover, regarding American military intervention, the Chinese newspapers held very different news frame from the other two by describing considerable sacrifice and pain of innocent people of Afghanistan seriously. For the story composition, daily newspapers in all three countries took the same way to report focusing on specific events with episodes.
