Through previous studies, it was found that news from legacy media, including television, has an agenda-setting effect and priming effect on the perceptions and attitudes of audiences about politics and war, and that film media also has an agenda-setting effect and political priming effect on war issues. However, it is difficult to find studies on the effects of war-related TV documentaries on media audiences. Therefore, in this study, An experimental study was conducted to investigate whether there is a change in 'recognition of the importance of security', 'will for South-North Unification' and 'will to participate in war in case of emergency' for the audience who watched the KBS special <100 Days of Invasion of Ukraine, Part 1 into the Fire>. As a result of the analysis, it was found that watching a war-related TV documentary reinforced the audience's 'recognition of the importance of security' and 'will for South-North Unification'. However, it was confirmed that watching a war-related TV documentary did not strengthen the audience's will to participate in war in case of emergency.

This is an experimental research with the theoretical background of agenda setting effect and elaboration likelihood model studying 'whether visual cues such as imagery and subtitle of TV environmental news have effect on the viewers' perception?', 'whether visual cues such as imagery and subtitle of TV environmental news have differential effect on the viewers' perception, depending on the viewers' involvement in the environmental issue?'. This experimental research found that the more highly exposed subjects considers environment issue more important than the less exposed, during the process, visual cues such as imagery and subtitle in TV news have an effect on agenda setting. Futhermore visual cues such as imagery and subtitle have stronger effect on the perception of the less involved than that of the more highly involved as a unified peripheral cue. However the effect of environmental involvement as independent peripheral cue couldn't have meaningful statistical support. Despite the fact that many previous researchers have shown that verbal cues of TV news have effect on the perception of viewers, little attempt has been made to investigate effect of visual cues on the TV viewers' perception. Therefore, this research has an important implication as an early proof in a new stream of visual agenda setting and elaboration research.

Many studies have been conducted to assess the health effects of climate change in Korea. However, there has been a lack of consideration regarding how the results of these studies can be applied to relevant policies. The current study aims to examine research trends at the agenda-setting stage and to review future ways in which health-related adaptation to climate change can be addressed within national public health policy. A systematic review of previous studies of the health effects of climate change in Korea was conducted. Many studies have evaluated the effect of ambient temperature on health. A large number of studies have examined the effects on deaths and cardio-cerebrovascular diseases, but a limitation of these studies is that it is difficult to apply their findings to climate change adaptation policy in the health sector. Many infectious disease studies were also identified, but these mainly focused on malaria. Regarding climate change-related factors other than ambient temperature, studies of the health effects of these factors (with the exception of air pollution) are limited. In Korea, it can be concluded that studies conducted as part of the agenda-setting stage are insufficient, both because studies on the health effects of climate change have not ventured beyond defining the problem and because health adaptation to climate change has not been set as an important agenda item. In the future, the sharing and development of relevant databases is necessary. In addition, the priority of agenda items should be determined as part of a government initiative.

In a situation where news usage through YouTube is rapidly increasing, this study investigated which attributes of issues news producers prominently report on based on the two-stage agenda setting theory to empirically investigate the influence of various news producers on YouTube. Through the research results, we confirmed that broadcasters have the influence to set the agenda and form public opinion on YouTube, and discovered the possibility of a two-stage agenda setting effect occurring in the YouTube environment. We criticized whether news producers abuse emotional words due to their partisanship when reporting political issues, and discussed that an emotional approach to political issues can have a negative impact on news users' perception of reality.

This study attempts to explore the inter-media agenda setting effect between television and Twitter based on the framework of the two-step flow theory. Twitter's increasingly important role in political communication can be effectively addressed by examining the process by which Twitter users form their opinions on television debate program. Content analyses of Twitter discussions after television debate of the Korean presidential candidates provided interesting insights into how Twitter's opinion leaders reflect on the televised debates. The results show that Twitter mentions rather focus on personality traits of the candidates while television debates emphasize the candiates' policy issues. Specifically, Twitter users mainly concentrated on the political ideology and morality of the candidates. In sum, Twitter seems to have its own way of influencing the public opinion separately from the television.

The purpose of this study was to examine the news attributes of the nuclear waste storage facility in Wido by conducting content analysis of two newspapers (Chosun Ilbo and Hangyoreh) and Ohmynews. Furthermore, this study measured the effects of news attributes on readers' attitude, opinion, and recognition of the event. The results of the content analysis indicated that all three newspapers focused on event-oriented coverage than issue-oriented one. Also, they only dealt with two issues-decision making process of the residents and rewards for residents-among a total of nine issues. That is, according to the hypothesis of the second-level agenda-setting theory, the media emphasize on a particular attribute while ignoring other attributes, which, in turn, make the particular attributes more salient. Based on the results of content analysis, this study conducted an experiment to measure the effects of media attributes on public recognition toward the attributes in terms of cognitive and of affective aspects. The results showed a significant relationship between media attributes and public attributes, which confirmed the effects of the second-level agenda setting. However, the transfer of attributes did not take place in affecting public opinion and public recognition of the event itself.

This study is to compare and analyze the policy decision process between Korea Long-term Care Insurance and Japan's using policy network theory as an analysis tool, and to lead political and theoretical implications. The result of the study is summarized as follows. First, a policy agenda about Long-term Care problem for the Elderly set up by the government-leading both Korea and Japan. and the number of policy participation(actors) increased to characteristics of policy process stage. but there is a difference between Korea and Japan in a background of setting up policy agenda about Long-term Care problem. Second, interaction among policy actors is corporative from early policy agenda establishment stage in Korea and Japan. but it changes to dissenting or critical rapidly as being announced the frame of system to the people. Also, it shows that main policy actors play a role in policy making decision and the connection structures of network is similar to both countries although it has a difference in the interaction frequency. Fourth, although the number of policy actors and the extent of their opinion reflection to the policy effect are different, it shows that policy network pattern is very similar to from policy agenda setting stage to parliament(The National Assemble) policy decision stage as a result of government-leading policy process. The theoretical and political implications of this study are as follows. The number and the variety of policy participation, the importance of establishing opened-interaction system, lots of limitation of policy making-decision process of Japan Long-term Care system, and exclusively the government-leading network has demerits about the reflection of too much government's opinion to the policy outcomes.

This study is an empirical study to see if the existing media effects have an effect on the perception of the audience in the media such as newspapers, TV, movies, etc., and whether the viewing of YouTube, an internet-based new media without gatekeeper, can affect the perception of the audience. For this study, 76 university students were divided into two groups, one group was asked to watch YouTube videos about no-buy campaign of Japanese products, and the other group was asked to watch short films for four weeks each, and then the perception and attitude of the issue were measured and analyzed through a survey. The results of the analysis showed that the audience who watched YouTube videos thought that no-buy campaign was more important than the audience who did not watch YouTube videos, and that they would participate more actively in no-buy campaign. The results of this study can be meaningful in that it confirmed the effects of the agenda setting effect and the priming effect of YouTube. It is expected that the theory of the media effect of YouTube will be established as the study on the audience effect in various fields such as politics, economy, society, culture of YouTube continues.

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.
