The present study was designed to study the media consonance of campaign news coverage by comparing the issue salience provided by each medium. To explore the issue of consonance, this study examined the relationship of campaign agenda at intermedia and intramedia level. The data analysis revealed that there was general consensus in setting the campaign agenda at the intramedia and the intermedia level. On the other hand, the research focus indicated there was media difference in reporting the campaign agenda over time. In the perspective of agenda-setting function, the exposure to news media with greater uniformity might result in greater agenda-setting effects, since the media makes the issues salient by giving more media attention. After all, the uniformity of issue salience among news media might influence "what issues to think about," resulting in limiting the range of democratic discussion.

This paper aims to grasp what propensity users have in their ideology from the comments in the Web Portal News and the Press Website News. Through these analytical results, the political propensities of not only the Web Portal News and the Press Website News but also the voters who use these news media could be grasped. The collection of data necessary for this study has been made from the comments of 174 news stories for about 90 days before the election day. For the analysis, T-test has been used in order to compare Naver News with Daum News, the Minjoo Party of Korea with the People Power Party, and the Press Web Site News with Naver News. As a result of the analysis, the comments of Naver News took the higher percentage in the positive writings about the candidates of the conservative party. but, in contrast, those of Daum News in that percentage were higher about the ones of the progressive party. Accordingly, it can be found that Naver News is mainly used by users with the politically conservative propensity, while Daum News is mostly used by those with progressive one.

Anchor-person scene detection is of significance for video shot semantic parsing and indexing clues extraction in content-based news video indexing and retrieval system. This paper proposes an efficient algorithm extracting anchor ranges that exist in sports news video for unit structuring of sports news. To detect anchor person scenes, first, anchor person candidate scene is decided by DCT coefficients and motion vector information in the MPEG4 compressed video. Then, from the candidate anchor scenes, image processing method is utilized to classify the news video into anchor-person scenes and non-anchor(sports) scenes. The proposed scheme achieves a mean precision and recall of 98% in the anchor-person scenes detection experiment.

This study pays attention to the fact that the fake news is attracting attention because it causes various social problems. To find out these fake news' influence, the study conducted the experiment to examine that the fake news related to the electronic voting system affects on the news users' attitude of using the system, intention to participate in the election through the system and reliability of news services. The results have shown that the fake news framed with negative contents reduced users' attitude of using the system and intention of participation in the election. Especially, as a result of examining the difference in the fake news' influence according to each news services, in the case that users recognized that the news was fake after exposing to the general internet news, the attitude of using the system and the intention of participation in the election have reduced and recovered again. However, users who exposed to Naver, Facebook believed the negative content of the fake news more strongly. Through these results, this study empirically confirmed that the fake news has a tendency to exert influence on users' cognitive dimension and to reinforce awareness in a direction consistent with the initial exposure information.

This study is for empirical verification of the influence of the introduction of smart phone on using the portal sites that were affected the most in the previous media environment. To achieve this, Web traffic data that are the result of smart phone users' practical Web uses have collected longitudinally and analyzed. The research results are the following: First, the use hours of portal sites have decreased about 15% and the page views have did about 35%, since using smart phones was diffused and habituated in earnest during the past two years. Using the community, news media, video, mobile, and game section of portal site sections have reduced. Second, the portal site portion of using smart phone Web is much more than that portion of using PC Web. More than two thirds of smart phone Web use traffic occurs in using portal sites, while more than one third of PC Web use traffic does in using that. Using the news media section is the most of using portal site sections on a smart phone. Third, since the introduction of smart phone, using the news media, communication, and life section of portal site sections have greatly increased, while the community, mobile, and game section have greatly decreased in the aggregate.

뉴스기사를 구성하는 NOD데이터는 VOD(Video on Demand) 데이터와는 달리 미디어의 종류 및 크기, 시간적인 접근 지역성, 사용자와 상호 작용성 등의 차이점을 가질 뿐만 아니라 새로운 뉴스기사가 수시로 생성되고 사용자가 인기도가 높은 기사와 최신의 뉴스기사에 더 많이 접근하는 특성을 가진다. 본 논문에서는 현재 서비스중인 전자신문의 로그파일을 분석하여 NOD 뉴스기사의 인기도가 Zipf분포와 다름을 보이고, 뉴스기사의 생명주기Lifr Cycle)에 따른 접근 확률분포 제시한다. NOD 데이터의 접근 편기성으로 인하여 데이터 캐싱을 통한 NOD 서버의 성능 향상을 기대할 수 있으나 뉴스기사의 생명주기가 짧고 접근시간대별로 사용자 접근형태가 변하는 등의 이유로 단순히 인기도만 고려한 캐싱은 빈번한 데이터 재배치 문제로 인해 높은 캐시 관리비용을 야기한다. 따라서 본 논문에서는 뉴스 기사의 접근 편기성에 나타나는 인기도(popularity)와 생명주기를 조합한 척도를 제안하고 이를 이용한 재배치를 제안한다.

인쇄산업의 가장 큰 위협의 하나인 디지털미디어의 도전에 균열이 생겼다. 종이미디어의 영향력을 거침없이 잠식하며 브레이크 없는 질주를 거듭해왔지만, 방향과 속도가 합당한가라는 원초적인 물음이 대두되는 상황이다. 미국의 유명 시사주간지 뉴스위크가 종이잡지 폐간을 번복하고 지난 3월 복간된 것과 디지털미디어의 일방적인 정보 전달 환경이 사람들의 인지능력을 심각하게 저하시킬 수 있다는 의학 전문가들의 우려가 이를 뒷받침한다.

“앞으로 KBS를 주목한다. 그러나 인터넷매체의 영향력도 더욱 커질 것이다.” 지난 5월 미디어분야 전문저널인‘미디어오늘’은 언론계 종사자, 전문가들을 대상으로‘향후 사회 전반에 가장 큰 영향을 발휘할 것으로 여겨지는 언론매체’에 대한 전망조사를 실시했다. 이 조사에서 KBS가 38표를 얻어 향후 영향력이 가장 높아질 것으로 기대됐으나 정작 눈길을 끈 것은 인터넷매체의 도약이었다. 오마이뉴스가 17표로 2위를 차지했으며 지난 3월 출범 1주년을 넘긴 미디어다음이 4위(9표)에 올랐다. 이어 프레시안이 5위(8표)였고, 자체 취재망이 없는 네이버도 10위(4표)에 들어서는 등 10위안에 인터넷매체가 4개나 포함된 것이다.

A theoretical model of information overload (Jackson and Farzaneh, 2012) with its three influential components (i.e., time, technology, and social networks) was empirically tested in the context of news consumption behavior considered as a communicative outcome. Using a national sample of South Korean adults (N = 1166), data analyses identified perceived information overload and large/diverse social networks positively associated with active and passive news consumption. Findings may imply the existence of individually varying cognitive threshold (i.e., tipping point), if crossed individuals cannot process information any further. News consumers may keep searching and receiving information to verify factuality of news even when they feel overloaded.
