In a formal speech, the speaker's voice has a variety of effects on the listener. Depending on the voice characteristics, the effectiveness and efficiency of the speech change as well. In the presidential election, the candidate's voice characteristics will affect the cognition of voters. Thus, we need to understand about the a more effective voice of candidate. This study proves whether voters will change their cognition if the candidate changes owe voice. If the cognition of voters can be changed according to the changed voice characteristics of the candidate, we will be able to explain what voices are needed for the candidate. We will also be able to suggest the necessary voice change strategies for effective speech. We describe cognition change of the voters according to the change of the voices of the presidential candidates by the dimension of the sori-engineering and the cognitive dimension. Hence, this study explains the voice characteristics and change strategies needed for candidates for effective speech.

Recently. VR( Virtual Reality) applications such as virtual studio and virtual character are wifely used In TV programs. and AR( Augmented Reality) applications are also belong taken an interest increasingly. This paper introduces a virtual screen system. which Is a new AR application for broadcasting. The virtual screen system is a real-time video augmentation system by tracking a chroma-patterned moving panel. We haute recently developed a virtual screen system.'K-vision'. Our system enables the user to hold and morse a simple panel on which live video, pictures of 3D graphics images can appear. All the Images seen on the panel change In the correct perspective, according to movements of the camera and the user holding the panel, in real-time. For the purpose of tracking janet. we use some computer vision techniques such as blob analysis and feature tracking. K-vision can work well with any type of camera. requiring no special add-ons. And no need for sensor attachments to the panel. no calibration procedures required. We are using K-vision in some TV programs such as election. documentary and entertainment.

As the use of mass media in modern politics grows, its influential power is getting larger than before. Therefore, fairness of broadcasting is identified as a very important factor in the current law. In particular, whether the mass media has balanced attitude toward election issues has been a critical point, which maked the current law have separate provisons to deal with it. As for the fairness and bias, most existing studies had focused on how long the media dealt with the specific political issues, which leads to only quantitative analysis. Also, most analysis of the contents had been based on very personal judgement and evaluation of researchers rather than following the criteria which is based on scientific method. This study introduced the AHP analysis method to compare the quantitative data and qualitative data altogether, which aims to develope the indicator for weighted measures and measurement of the fairness. Research findings reveals that each broadcaster has, MBC was highly biased and KBS and SBS followed that. Compared with existing studies regarding the political fairness of the media.

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.

To compare whether broadcast fact-checking news, which aims to overcome the limitations of objective reporting, ensures fairness, we analyzed 227 fact-checked news stories aired on the main news of KBS, MBC SBS, TV Chosun, JTBC MBN, and YTN from January 1, 2022 to May 31, 2022, when the 20th presidential and local election campaigns were held. The analysis showed clear differences in fact-checking targets and narratives by broadcasters. In general, MBC, JTBC,and YTN were more likely to favor liberal parties such as the Democratic Party, while TV Chosun had a lot of narratives favoring the conservative camp. SBS and MBN were relatively neutral. KBS seemed to be trying to remain outwardly neutral. SBS and TV Chosun were the most active in fact-checking, but they covered a wide range of issues and were characterized by a bias toward contextualizing issues that viewers were curious about, rather than clarifying the facts. The projection of ideological bias by broadcasters in fact-checking narratives is a challenge that needs to be overcome.

The Remote Procedure Call(RPC) has been traditionally used for Inter Process Communication(IPC) among precesses in distributed computing environment. As distributed applications have been complicated more and more, the Mobile Agent paradigm for IPC is emerged. Because there are some paradigms for IPC, researches to evaluate and compare the performance of each paradigm are issued recently. But the performance models used in the previous research did not reflect real distributed computing environment correctly, because they did not consider the evacuation elements for providing security services. Since real distributed environment is open, it is very vulnerable to a variety of attacks. In order to execute applications securely in distributed computing environment, security services which protect applications and information against the attacks must be considered. In this paper, we evaluate and compare the performance of the Remote Procedure Call with that of the Mobile Agent in IPC paradigms. We examine security services to execute applications securely, and propose new performance models considering those services. We design performance models, which describe information retrieval system through N database services, using Petri Net. We compare the performance of two paradigms by assigning numerical values to parameters and measuring the execution time of two paradigms. In this paper, the comparison of two performance models with security services for secure communication shows the results that the execution time of the Remote Procedure Call performance model is sharply increased because of many communications with the high cryptography mechanism between hosts, and that the execution time of the Mobile Agent model is gradually increased because the Mobile Agent paradigm can reduce the quantity of the communications between hosts.

The study attempts to introduce 'Gotcha Journalism' to the Korea journalism, research and analyze it. Gotcha journalism is the journalistic reporting attitude that the journalists repeatedly and intensively reports public figures, especially politicians' mistakes or happening. 'Gotcha' is abbreviation of "I got you", frequently used in the English and American culture. In order to get the goal of this study, several journalists who are currently working for Chosun, Joongang, Dong-a, Hangyore, Kyunghyang and Seoul, national covering daily newspapers. In addition, the reporters who work for KBS, MBC, and SBS were Interviewed. All journalists who have been worked more than 5 years at the politic department were selected as interviewees. Thus, Intensive interviews are prime source of this study. Based the result of the research, gotcha journalism is externally derived from obsessive interest of Korean people to politics. Internally, it is easy to report happening or mistakes rather than big argument or ideological agenda of the politicians as news for journalists and to catch readers. In addition, the competition with advertising income accelerates this situation. And gotcha journalistic reporting behavior or attitude highly relates to political propensity of the newspapers or broadcastings. Especially some of the newspapers take gotcha journalism as a political struggling tool. It is appeared that another major cause for gotcha journalistic reporting behavior is customer-driven news production.
