그동안 커뮤니케이션 효과에 관한 많은 연구들이 진행되어 왔다. 특히 의제설정 관련 이론들은 맥콤과 쇼(McCombs & Shaw, 1972)[1]에 의해 최초의 연구가 발표된 이후, 수백 편 이상의 관련 연구들이 축적되어 왔다. 이러한 연구들을 통해서 미디어가 중요하게 보도한 의제는 수용자 의제에 많은 영향을 미친다는 사실을 누구도 부정하기 어렵다. 그러나 이러한 연구들은 주로 언어텍스트를 중심으로 이루어져왔다. 그러나 신문이나 인터넷 미디어와는 달리, TV 미디어에서 수용자들은 언어텍스트에 의해서만 정보를 얻는다고 보기는 어렵다. 본 연구는 텔레비전 뉴스 보도에서 영상과 자막이 수용자의 의제설정 효과에 어떤 영향을 미치는지 실험을 통해 검증해보고자 한다.

The research objective of this study is to analyze the aspects of small group decision-making process based on reading news reports in the context of the socio-scientific issues (SSI) activity related to climate change. Twenty-two high school students from Gyeonggi Province, South Korea, were asked to read two news reports on the UN climate change conferences and take a stance on joining the Paris Agreement both as an individual and as a small group. The news reports were analyzed in terms of genre, discourse, and style adapting the critical discourse analysis (CDA) and the decision-making processes of the small groups were examined on recognizing a problem and evaluating alternatives and decisions. The results from analyzing the news reports denoted that the Paris agreement is not only related to finding ideal solutions to climate change, but rather, connected to political or economic interests and power relationship. In the stage of recognizing a problem, meanwhile, different frames which students recognize the Paris agreement and discourses in the foreground of the news reports were the critical causes in terms of identifying the problem. In the stage of evaluating alternatives and decisions, the equity and fairness were the criteria for the small group discussions. This study implies the necessity of the scientific literacy instruction to develop the ability to critical reading in the context of the SSI.

According to Peter Berger and Thomas Luckmann, people do not live understanding the objective existence, but live defining the reality that is socially constructed. This study analyzed the frame of news report dealing with public figures to inquire into the following subjects: Which group is defined as a public figure? Which role and obligation are required for a public figure? Which standard can be set to judge right and wrong of behavior of a public figure? The research result shows that the press mentioned with most frequency politicians and broadcasting-related people as public figures. In case of politicians, the press focuses most on scandals related to their duties and qualities, while in case of broadcasting-related people, the press focuses most on scandals relevant to ethical problems.

A researcher, who is a member of an academic society, is required to write a report on his or her research and present it at an academic workshop in order to have the contents of the research recognized by others. In order to do that, the researcher frequently has to look up the web pages of each workshop for information such as the submission deadline, paper information, announcements and news. On the other hand, the academic society mostly relies on e-mail or bulletin board to send information about itself to its members to inform its members about its latest news or developments. A system where the researcher can gain all the information required through just a single click and the academic society can provide its members with the necessary information through a simple step is required for the ease of both side. We will take a look at the domestic status of researches being done on such systems where the RSS standard has been applied and suggest a RSS-based dissemination model where the concept of personalization has been applied to satisfy the needs of the individual user.

In this paper, we propose a novel approach to improve the performance of the Convolutional Neural Network(CNN) word embedding model on top of word2vec with the result of performing like doc2vec in conducting a document classification task. The Word Piece Model(WPM) is empirically proven to outperform other tokenization methods such as the phrase unit, a part-of-speech tagger with substantial experimental evidence (classification rate: 79.5%). Further, we conducted an experiment to classify ten categories of news articles written in Korean by feeding words and document vectors generated by an application of WPM to the baseline and the proposed model. From the results of the experiment, we report the model we proposed showed a higher classification rate (89.88%) than its counterpart model (86.89%), achieving a 22.80% improvement. Throughout this research, it is demonstrated that applying doc2vec in the document classification task yields more effective results because doc2vec generates similar document vector representation for documents belonging to the same category.

This study analyzed media reports on the Address of Things, which are being introduced through the amendment of related law and pilot projects. The titles and its texts in the media's reports were collected by searching for 'Address of Things' on the Naver News Platform. Then, we analyzed the corpus using by topic modeling and network analysis. As a result, there were four topics: 'Promotion of the address of things system', Proof of assigning Address of Things', 'Improvement of usage of the Roadname Address Systems', and 'Education and public relation for the address activation'. It was confirmed that the topic 'Proof of assigning Address of Things' was the main agenda. We presented some implication by comparing the results with the 「3rd Basic Plan for Address Policy (2018-2022)」 of the Ministry of Public Administration and Security.

This study aims to explore the issue of drones and crime in newspaper articles. BIG KINDS, an online news archive of the Korea Press Foundation, collected 1,213 newspaper articles that met the terms of "drone" and "crime" in 11 central and 28 regional comprehensive newspapers between January 1, 1990 and May 1, 2021. Among them, we perform keyword frequency, centrality analysis, network structure construction, CONCOR analysis, and density matrix analysis on 117 key keywords. According to the analysis, the main issues were classified into eight, and the report analysis on drones and crimes in newspaper articles showed that the government's policy-making and social problems on protecting people's privacy, preventing illegal filming, securing navigation safety, social security and resolution. This study attempts to expand the field of humanities and social studies related to drones and crime, and specifically suggests the current status and counterplan against drone-related crimes as policy implications and media implications.

This article reviews a few academic discussions in our geological society. The author presents his opinion on the discussions regarding the ages of the Okcheon Group, Myogog Formation, and hominid footprints of the Jeju Island, as well as on the inaccurate reportage in mass media. The academia advances via healthy debates and discussions. The arguments for and against Darwin's "Origin of Species" and scientific debates regarding Wegener's "Continental Drift Hypothesis" are well known. In academic debates or discussions, authority should not be involved in any form. Academic research should be conducted based on scientific principles and evidence-free of personal preferences or other nonacademic factors. Opponents should challenge with scientific approaches, suggesting alternatives based on science. Opposition without scientific basis is not productive in conducting academic research in search of scientific truth. Often, the news media delivers inaccurate information to the public-intentionally or unintentionally. There must be a mechanism to immediately identify and rectify inaccurate, false, or fake information for the benefit of the public and the credibility of the news media.

The purpose of this study was to investigate consumers' perceptions on monosodium L-glutamate (MSG) in social media. Data were collected from Naver blogs and Naver web communities (Korean representative portal web-site), and media reports including comment sections on a Yonhap news website (Korean largest news agency). The results from Naver blogs and Naver web communities showed that it was primarily mentioned MSG-use restaurant reviews, 'MSG-no added' products, its safety, and methods of reducing MSG in food. When TV shows on current affairs, newspaper, or TV news reported uses and side effects of MSG, search volume for MSG has increased in both PC and mobile search engines. Search volume has increased especially when TV shows on current affairs reported it. There are more periods with increased search volume for Mobile than PC. Also, it was mainly commented about safety of MSG, criticism of low-quality foods, abuse of MSG, and distrust of government below the news on the Yonhap news site. The label of MSG-no added products in market emphasized "MSG-free" even though it is allocated as an acceptable daily intake (ADI) not-specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). When consumers search for MSG (monosodium L-glutamate) or purchase food on market, they might perceive that 'MSG-no added' products are better. Competent authorities, offices of education and local government provide guidelines based on no added MSG principle and these policies might affect consumers' perceptions. TV program or news program could be a powerful and effective consumer communication channel about MSG through Mobile rather than PC. Therefore media including TV should report item on monosodium L-glutamate with responsibility and information based on scientific background for consumers to get reliable information.

This study identifies the terms frequently used together with energy in online science news articles and topics of the news reports to find out how the term energy is used in everyday life and to draw implications for science curriculum and instruction about energy. A total of 2,171 online news articles in science category published by 11 major newspaper companies in Korea for one year from March 1, 2018 were selected by using energy as a search term. As a result of natural language processing, a total of 51,224 sentences consisting of 507,901 words were compiled for analysis. Using the R program, term frequency analysis, semantic network analysis, and structural topic modeling were performed. The results show that the terms with exceptionally high frequencies were technology, research, and development, which reflected the characteristics of news articles that report new findings. On the other hand, terms used more than once per two articles were industry-related terms (industry, product, system, production, market) and terms that were sufficiently expected as energy-related terms such as 'electricity' and 'environment.' Meanwhile, 'sun', 'heat', 'temperature', and 'power generation', which are frequently used in energy-related science classes, also appeared as terms belonging to the highest frequency. From a network analysis, two clusters were found including terms related to industry and technology and terms related to basic science and research. From the analysis of terms paired with energy, it was also found that terms related to the use of energy such as 'energy efficiency,' 'energy saving,' and 'energy consumption' were the most frequently used. Out of 16 topics found, four contexts of energy were drawn including 'high-tech industry,' 'industry,' 'basic science,' and 'environment and health.' The results suggest that the introduction of the concept of energy degradation as a starting point for energy classes can be effective. It also shows the need to introduce high-tech industries or the context of environment and health into energy learning.
