As the number of videos uploaded on live streaming platforms rapidly increases, the demand for providing highlight videos is increasing to promote viewer experiences. In this paper, we present novel methods for predicting highlights using chat logs and audio data in videos. The proposed models employ bi-directional LSTMs to understand the contextual flow of a video. We also propose to use the features over various time-intervals to understand the mid-to-long term flows. The proposed Our methods are demonstrated on e-Sports and baseball videos collected from personal broadcasting platforms such as Twitch and Kakao TV. The results show that the information from multiple time-intervals is useful in predicting video highlights.

Most of the games in the RTS genre, including games such as Starcraft and LOL, which are considered the most successful works in E-sports, have become increasingly uniform and boring. In order to make more changes in a uniform and boring system, I thought it could be solved through a combination of genres that have been fully developed and verified, so I tried to present a new game paradigm. To this end, let's focus on the genres of RTS andt TCG among the popular game genres and present a new paradigm by combining the dynamic and static features of these two genres. The new Real-Time Trading Card (RTTC) genre of game system proposed in this paper refers to a new type of game system that fuses the dynamic and static elements of the game. This mixed genre can be a new paradigm for games that can satisfy both gamers and viewers by minimizing the uniformity of the game while adding the randomness of cards to the characteristics of RTS called real-time warfare.

Public data has been transformed from provider-oriented information disclosure to a form of personalized information sharing centered on individual citizens since government 3.0. As a result, the government is implementing policies and projects to maximize the value of public data and increase reuse. This study analyzes the issues related to public data in the news and seeks the status of government agencies and government projects by issue. We conducted semantic analysis on domestic online news and public agency bidding information including public data and conducted the work of linking major key words derived with social and economic values inherent in public data. As a result, major issues related to public data were divided into broader access to public data, growth of new technology, cooperation and conflict among stakeholders, and utilization of the private sector, which were closely related to transparency, efficiency, participation, and innovation mechanisms. Also major agencies of four issues include the Ministry of Strategy and Finance and Seoul, Ministry of Culture, Sports and Tourism and Gyeonggi-do, Ministry of Trade, Industry and Energy and Incheon, and Ministry of Land, Infrastructure and Transport and Gyeongsangbuk-do.

UHD (Ultra High Definition) broadcasting technology, and UWV (Ultra Wide Vision) which is the high quality panoramic video of wide view angle based on UHD, were commercialized in Korea for the first time in the world, and those are representative realistic video technologies that maximize the user's sense of presence. By comparing the user's subjective reaction of UHD and UWV, the purpose of this study is to systematically establish the user's subjective video quality evaluation. For this purpose, a large screen projection experiment is designed by setting the screen size (4k x 2k, 8k x 2k) and content types (sports, landscape, concert) as variables to measure the user's subjective video quality evaluation and satisfaction. As a result of the study, the users' evaluation of UWV was higher than UHD in all items of subjective video quality, and satisfaction. Moreover, the results showed the significant differences depending on the video contents. Based on the results of the research, the study proposed the points necessary for the development and commercialization of UWV panoramic technology, and suggestions for the future research.

This study is a paper on the recognition of college students about the long-take shot technique which is often used to give a sense of reality and realism to films. 13 surveys were conducted on 92 students, including their perception of long-take films, their feelings after watching the film, satisfaction, and future prospects. Participants in the surveys consisted of 23 students in the health field, 16 students in the natural field, 41 students in the arts and sports field, and 13 students in the engineering field. As a result of the surveys, 68.8% of students answered "I know" about long-take film, and the feeling after watching the long-take film was found in the order of reality (realism) 68.8%, tension 16.1%, and boredom 15.1%. After watching the long-take film, 16.1% of students chose "Very satisfied" and 31.2% chose "Satisfied". Future prospects for long-take film showed high with 17.2% for "It will be developed very much" and 48.4% for "It will be developed". Preference for long-take film and general film was 67.7% for "long-take film" and 32.3% for "general film", showing high preference for long-take film. As a further research project, more in-depth surveys will be conducted targeting broadcasting & media contents majors in their 20s, and the long-take films used according to the story development process in domestic films will be analyzed.

This study was conducted using text mining and network theory to extract useful information for application for occupancy and performance of permit tasks contained in the permit contents from the permit register, which is used only for the simple purpose of recording occupancy permit information. Based on text mining, we analyzed and compared the frequency of vocabulary occurrence and topic modeling in five regions, including Seoul, Gyeonggi, Gyeongsang, Jeolla, Chungcheong, and Gangwon, as well as normalization processes such as stopword removal and morpheme analysis. By applying four types of centrality algorithms, including stage, proximity, mediation, and eigenvector, which are widely used in network theory, we looked at keywords that are in a central position or act as an intermediary in the network. Through a comprehensive analysis of vocabulary appearance frequency, topic modeling, and network centrality, it was found that the 'installation' keyword was the most influential in all regions. This is believed to be the result of the Ministry of Environment's permit management office issuing many permits for constructing facilities or installing structures. In addition, it was found that keywords related to road facilities, flood control facilities, underground facilities, power/communication facilities, sports/park facilities, etc. were at a central position or played a role as an intermediary in topic modeling and networks. Most of the keywords appeared to have a Zipf's law statistical distribution with low frequency of occurrence and low distribution ratio.
