우리나라에 대한 사이버 공격의 배후로 추정되는 북한의 사이버조직에 우리는 얼마나 알고 있을까? 사이버 공간의 특성상 공격 흔적이 남지 않기에 언론사들은 북한의 사이버조직과 관련하여 일관된 정보를 거의 제공하지 못하고 있다. 따라서 갈수록 진화하는 북한의 사이버 공격에 효과적으로 대비하기 위해 본 논문에서는 비록 인터넷에 공개된 자료(논문, 기사 등)라 할지라도 이를 통해서 북한 사이버조직 현황 및 주요 공격사례를 중심으로 관련 정보를 살펴보고자 한다.

기존 신문이나 티브이가 아닌 온라인과 모바일로 뉴스를 보는 사람이 더 많아지면서, 포털 사이트 뉴스난에 다른 언론사의 기사보다 더 많이 노출되기 위한 경쟁의 심화로 뉴스 어뷰징은 심각한 사회 문제로까지 대두되었다. 본 논문은 온라인상에서 생성, 유통되는 많은 뉴스 중에서 이용자의 시간을 낭비하고 양질의 정보를 찾기 힘들게 하는 뉴스 어뷰징을 판단하는 모델을 제안한다. 제안된 모델은 크롤링 기술을 사용하여 뉴스의 제목과 내용을 가져온 후 인공지능 기술을 이용한 유사도 검사로 기사의 어뷰징 여부를 판단하여 양질의 뉴스 정보를 사용자에게 제공될 수 있다.

가짜뉴스는 뉴스 기사 형식을 갖는 날조된 정보를 의미하며, 최근 모바일 인터넷 장치의 보급과 소셜 네트워크 서비스의 대중화로 온라인 확산이 가속화되고 있다. 기존 연구는 가짜뉴스의 탐지를 위해 뉴스의 주제목, 부제목, 리드, 본문 등 뉴스 기사를 이루는 구성요소를 비롯하여 언론사, 기자, 날짜, 확산 경로 등의 메타 데이터를 대상으로 분석하였다. 그러나 뉴스의 제목과 본문 및 메타 데이터 등은 내용 수정이 쉬워, 다량의 데이터를 학습한 모델이라 하더라도 높은 정확도를 장기간 유지하기 어려울 수 있다. 이러한 문제점을 해결하기 위하여 본 논문은 합성곱 신경망을 이용해 문맥 정보를 분석하고 장단기 메모리 기반의 감성분석을 추가로 수행한다. 문맥 정보와 가짜뉴스 유포자가 쉽게 수정할 수 없는 감성 변화 패턴을 활용하여 성능이 개선된 가짜뉴스 탐지 모델을 제안한다.

This paper aims to review Ahn Jae-Hong's studies on the history of the Korean press from the perspective of research history focussing his "Josun Shinmun Sosa(A Short History of the Korean Press)" published in 1935. For this purpose major discussions with respect to journalistic history during the Japanese occupation period are reviewed. The result reveals that Ahn Jae-Hong's studies using a comparative method and a social historical approach are judged to be the most representative outcomes at that time. The "Josun Shinmun Sosa" first explains "Inhaeng Jobo" and "Jeobo" as an origin of newspaper, and then explains various subjects on newspaper phenomena in the latter era of the Chosun Dynasty such as participants of major newspapers, the tone of newspapers, the analysis of newspaper character through evaluation of main articles, the system of newspaper, newspaper advertisements, pro-Japanese newspapers, newspapers managed by Japanese, newspapers for overseas Korean, etc. But partly it gives a general description rather than a detailed research due to the nature of contributions to the newspaper, and also includes an objective analysis and a subjective impression together. Nevertheless his researches can be valued as pioneering pieces of work as they comprehensively handled various objects of study on newspapers and gave new angle and orientation of interpretation on the newspaper phenomena at that time. Also it is judged that they had an effect on the period division as well as the description methods for the study of the history of the Korean press.

Baker et al. (Quarterly Journal of Economics, 134, 1593-1636, 2016) developed an Economic Policy Uncertainty (EPU) index for South Korea in the same way as the U.S. EPU Index. However, the South Korean EPU index of Baker et al. (2016) has limitations as it did not fully reflect South Korean situation in terms of keyword selection and the selection of newspapers. We develop monthly South Korean economic policy uncertainty indexes with different keywords and news media. Various analyses have been conducted in order to examine the usefulness of the newly compiled indexes.

This paper aims to investigate ideological preferences of news media outlets by looking at the news coverage of North Korea-Russia summit in April, 2019. The meeting has gained attention in South Korea, China, Japan and America in that the historical meeting will reflect the future direction for denuclearization on the Korean peninsular and the peace in the world. Given this, in particular, a special attention is paid to the editorials and headlines of news articles reported in two Korean quality newspapers, DongA Ilbo and Hankyoreh because both are quality newspapers, but are ideologically different. To achieve objectivity and fairness, the same issues dealt with during the summit were compared and analyzed within Martin and White (2005)'s Appraisal framework. As a result, it was found that in editorials of DongA Ilbo showed a negative stance to the summit by employing the 'attitude' factor, whereas the Hankyoreh was overwhelmingly positive toward the issue, also by employing the 'attitude' factor. The political stance is likely to be in line with those shown in the headlines of news articles from each newspaper. That is, it is clear that each news outlet shows its ideological stances to news consumers through linguistic expressions, in that both editorials and the headlines of news articles express their political preferences to the summit by means of linguistic appraisals.

The purpose of this study is to investigate the actual attitude of the major newspapers and broadcastings about public health policy during last $17^{th}$ presidential election and $18^{th}$ election for a member of the National Assembly and apply it to the study of procedure of making decision of policy as a fundamental data. Two researchers surveyed and analyzed all articles from three broadcasting stations, KBS, MBC, and SBS, and from four newspaper companies, Donga, Jungang, Chosun, and Hangyoreh. Among the major articles, the articles related to policies are ranked in last (10.8%). And among the reported 284 articles related to the policies, the social section (75 articles, 26.4%) and the economic section (73 articles, 25.7%) took part of over 50% of all. However, the articles related to public health policy took part of only 9.9% (28 articles). Among the articles of public health policy, the articles related to the cost of the medical service were ranked in the first (39.3%). Therefore, to solve the problems of the major public health policy, it needs effort to develop the public health policy and use the media to realize the developed policies.

Facts, which constitute news, are as free as air. When they are transformed into news via labor and capital investment of a news organization, the news is deemed to have property values, and the media can claim exclusive rights over the news. The copyright law protects the originality of a work, the uniqueness of reporter's analysis, the selection of words, the arrangement of materials, and the emphasis given on particular points. The name of the game of copyright infringement lies in the infringement of the similarity of the method of expression, not the infringement of the subject. Even though news articles convey information by specifying factual elements of an event or accident, they still have some originality. The judgement that news articles lack of originality is inconsistent with the purpose of the copyright law. Therefore, the law should be amended to articulate that the unauthorized use of news articles without a proper citation shall be the subject of legal action, and courts should decide related cases accordingly.

Today a lot of functional areas of a firm are operated on the Web. Online shopping malls analyze web log recording customers' activities on the web to connect them to business outcomes. Not only commercial websites, but online news sites also need to collect and analyze web logs to understand their news readers' interest. However, little research has been performed yet. In this research we mined the web access log of an online news website and conduct Market Basket Analysis to uncover the association rules among the categories of news articles. The research is composed of two stages: 1) Identifying the individual session of a visitor; 2) Mining association rule from news articles read by each session. We gather 7-day access logs two times. The results of log mining and meanings of association rules are suggested with managerial implications in conclusion section.

The purpose of this study is to explore the social perception on geoscience using a big data analysis and to propose a way to enhance people's perception on geoscience. For this, 5,044 media articles including geoscience produced by 54 media companies from January 1, 2010 to April 14, 2022. were analyzed. Big data analyses were applied. The results of analyses are as follows: Media articles consist of key words of research institute, some countries of America, China and Japan, City of Pohang, CEO of KIGAM. And geology, industry, development of mineral resources, environment, energy, nuclear power, and groundwater are highlighted as key words. Also, it is confirmed that topics related to geoscience such as expert, environment and research institute are not individually isolated, but interconnected and linked to topics in the center of future, industry, and global. Based on this result, ways to enhance people's perception on geoscience were discussed.
