Due to the development of online media platforms and the COVID-19 incident, the mass production and consumption of digital video content are rapidly increasing. In order to select digital video content, users grasp it in a short time through thumbnails and teaser videos, and select and watch digital video content that suits them. It is very inconvenient to check all digital video contents produced around the world one by one and manually edit teaser videos for users to choose from. In this paper, keyframes are extracted based on YCbCr color models to automatically generate teaser videos, and keyframes extracted through clustering are optimized. Finally, we present a method of producing a teaser video to help users check digital video content by connecting the finally extracted keyframes.

This research wanted to examine what narratives and discourse were being formed in web drama contents young generations were going crazy about. To understand the characteristics of such love epics and to know what narratives were being formed based on narrative structures and comments, this research specifically used the web drama produced up to the season 4 for the first time in Korean web drama history with a large number of accumulated views. It was found that the narratives of the drama composed the romantic relationships of four couples as independent episodes, and realistically highlighted separations and reunions of those couples, and suggested concrete methods to solve agonies and conflicts they would experience in such relationships. And, in user comments, there emerged relational narratives confusing friendship and love between partners of opposite sex, narratives regarding the third person as enemy, and narratives on typical sex roles in such romantic relations. And, the culture seeking subjective love style and sharing and sympathizing with the love histories also appeared.

We study, in terms of VoIP user assessment of voice quality, the synchronization of measurement system is important. Commonly the synchronization system uses NTP(Network Time Protocol) or GPS(Global Positioning System), these synchronization method has time error of distance, system overhead of data processing, and system specialized clock error. we propose and implement the synchronization method to correct time error between two measurement system in the internet. So the time synchronization of systems can get time error, then user assessment of voice quality become reliable.

By improving performance of mobile machine(3D engine, 3D accelerator chip set, etc) and developing wireless network technology, a demand for actual contents of users is being increased rapidly. But, there are some difficulties yet for the speedy development of actual contents because of the limitation of development resources that is dependent on each mobile device's different performance. In general, much of the animated character-creation work for mobile environment is still done manually by experienced animator with the method of key frame processing. However, it needs a lot of time and more costs for creating motion. Additionally, it is possible to cause a distortion of motion. In this paper, I solved the difficulties by using a optical motion capture system, it was able to acquire accurate motion data more easily and quickly, and then it was possible to make 3D dance contents efficiently. Also, I showed techniques of key reduction and controlling frame number for using huge amounts of motion capture data in mobile environment which requires less resources. In making 3D dance contents, using an optical motion capture system was verified that it was more efficient to make and use actual-reality contents by creating actual character motion and by decreasing processing time than existing method.

The exponential increase of digital contents brought about the e-Challenge crisis to the librarians. How can all the e-resources be managed effectively? How can we detect all the broken links? How can we assist the users to the right resources? This paper concentrates on building CLICK(Cooperative Link Center in KOREA) as a knowledge compass by collecting diverse science & technology information and creating tight coupled links between information resources for reference linking and providing users with the optimal route for the resource per user. If the publishers, Abstract & Index DB, Searching Portal, Electronic Libraries, Full-text DB and Aggregator can be linked by using a standardized way through a CLICK, the service channels can be diversified. Users can select the channels without rein under according to a use purpose and conditions.

The purpose of this study is to derive implications through a comparison of the current status of catalog enriched content services provision in U.S. public libraries and domestic public libraries. In addition, we are seeking ways to improve the catalog enriched content services for domestic public libraries in the future. From early September to mid-October 2023, specific books were searched on public library websites in the U.S. and Korea, and the functions of the enriched content services shown in the search results were compared. The results are as follows: First, domestic public library enriched content services require a separate company to develop and provide an enriched content services solution. Second, the enriched content services platform must discover domestic information sources that can be utilized in the areas of book-centered, book recommendation, and community engagement. Third, it is necessary to develop enriched content using public data such as the Library Information Naru. Fourth, each integrated library must that data generated from local community engagement services can be utilized as an enriced content service.

SNS media is gaining its media share with the benefits of digital technology, such as the convenience of physical access and the entertainment and interactivity of contents, and are becoming a part of users' lives. As media contents consumers move from traditional media to SNS, marketing communication activities are rapidly adapting to leading SNS platforms such as Facebook. This study compares how users perceive four advertisement attributes in each SNS, focusing on Facebook, Instagram, Kakao Story, and Twitter, where the media content creation and consumption systems are relatively similar to each other. The impact on eWOM intention was identified. In addition, we discussed effective SNS operation.

Many libraries and information centers offer various resources on their web sites and web reference is one of them. However, it can be quite burdensome for individual libraries to build a reliable database while sorting through countless web data. The attempts to build a collaborative database have been also unsuccessful due to heavy workload of librarians and financing problems. This study seeks to propose a UCC(User Created Contents)-based web reference database created by general users including librarians. It is an open reference database where everyone can contribute regardless of their affiliation and library types (for librarians), Also, it requires metadata scheme to standardize web-based references. By setting the initial metadata, it can present a basic guideline for users to post web references.

UCC, an abbreviation for User Created Contents, is not only a symbol of desire but also a product of creativity that a producer contains his or her subjective disposition. More and more UCC tend to have significantly increased in Web 2.0 environment. However, the research on the contents as a creative product has rarely been processed. It may be fairly said that this results in the indifference of researchers in the special field like the political contents since UCC is usually produced by amateurs. Producers' various desire is unlikely revealed, which leads to the flow of users into open media such as the Internet. It could also be available to represent the property, of plural visual language signs in a field. Moreover, UCC has the attribute of re-mediation in effective communication, so the differences between the semiotic properties in the Internet contents could be a significant material for researches. This could contribute to establish a theoretical system for the visual communication. Therefore, this study aims to analyse the signification of the political video UCC, . To develop this analysis, I apply Greimas' Generative Trajectory of Signification Theory to the text, or the UCC. He classifies it as three structures: deep structure, superficial structure, and discourse structure. As a result, the text shows meaningful contents delivering core political messages. In addition, this approach could exam that 'Obama Syndrome' in American recent presidential campaigns is caused by web 2.0 based on Internet campaigns including video UCC.
