The social media paradigm centered on videos continues to deepen due to the diversification of 5G devices, high-definition and immersive SNS. The purpose of this study is to propose various utilization strategies and measures through the analysis of the current status of YouTube channel operation and provided contents operated in public libraries. In this study, 44 libraries in Korea that have opened and operated Library YouTube Channel and 12 libraries that actively utilize library YouTube channels with more than 1,000 subscribers were surveyed for the current status of subscribers, views, video count data, and contents and delivery methods of Library YouTube Channel. Based on the analysis results, the library's YouTube channel was proposed to utilize the library's YouTube channel, 1) to secure the specificity and purpose of the library's YouTube channel, 2) to promote and enhance access to the YouTube channel, 3) to improve the YouTube channel to user-friendly interface, 5) to plan and provide library expertise and educational contents, 6) to operate the integrated YouTube channel, and 7) to provide user-based content.

It is true that internet provides consumers with an efficient way to search information with minimal effort and cost, which facilitates better decision making. Especially, previous studies revealed that the online word-of-mouth marketing is widely used as a source of consumers' information seeking and purchase decision making. Even with this importance of the online word-of-mouth communication on internet few researches have systematically addressed the issue. This study investigates the effect of consumers' motives on perceived usefulness of word-of-mouth marketing in online shopping mall contents. The results are as follows: First, choice uncertainty, perceived sacrifice, and social pressure play an important role for perceived usefulness of word-of-mouth marketing. Second, perceived usefulness has directly affected consumers' quality perception. Thus, it is essential for internet companies to find ways to encourage their customers to engage in word-of-mouth communication on their websites.

Real-time streaming services over the Internet have increased with the explosive growth of the various mobile platforms, with a focus on smart phones, and the demand for them is growing. In addition, the bandwidth occupied by the streaming services over the Internet had already surpassed 50% in 2010. Because of the shortage of network bandwidth for multimedia services traffic, restrictions on quality and capacity will become more and more serious. CCN is a future Internet architecture that improves how existing host-based Internet architecture handles content-oriented structure, but it is designed for the transmission of general contents and is not suitable for transmitting real-time streaming contents. In this paper, we focus on the inefficient aspects of CCN and propose a hierarchical grade-based scheme for real-time service for a more efficient environment in real-time streaming services. Experiments have shown better performance in terms of bandwidth, network load, and reliability.

This research is focused on the development of the proprietary database embedded in the OTT device, which is used for searching and indexing video contents, and also the development of the search algorithm in the form of the critical components of the interface application with the OTT's database to provide video query searching, such as remote control smartphone application. As the number of available channels has increased to anywhere from dozens to hundreds of channels, it has become increasingly difficult for the viewer to find programs they want to watch. To address this issue, content providers are now in need of methods to recommend programs catering to each viewer's preference. the present study aims provide of the algorithm which recommends contents of OTT program by analyzing personal watching pattern based on one's history.

Cultural contents are the most important factor in high speed and high quality data communication. High-quality content includes VR and AR technology, and a variety of high-quality content can be streamed over wireless mobile phones via smartphones. In addition, network and wired/wireless communication are inevitably required in an Internet of Things (IoT) environment in which things are connected to a wireless Internet. IoT is used in various network technologies such as 4G, 5G mobile communication, WIFI wireless LAN, Bluetooth and so on. It is a technology that can use the connection between things anytime, anywhere, and can be achieved in a wireless mobile communication environment. Therefore, in this paper, we study data error compensation estimation method which can reduce data error based on mobile communication channel environment analysis so that high quality contents can be serviced even in high speed mobile environment.

The purpose of this study is to analyze the success and failure of the movie made by the original game by comparing the box office environment of the movie made by the original game and to derive the necessary elements to make a good original movie. The specific analytical content studied the specific successes and failure factors of the remake of the game with , , and . Analyzes of the research show that the audience can be divided into game fan and non - game fans, and how to reflect the expectation on both sides of the movie is an important factor in making the movie. Also, games of different styles and genres from other themes can not be created in the same way as remixing movies, but flexible diversity and management are needed. Unconditional scenarios of games or game switching of movies can not be popular among the public, and it is very important to analyze specific target audiences.

This study proposes service content that helps people stay in the right posture in their daily lives to manage the pain of musculoskeletal diseases. Resistance factors and induction factors were analyzed through a survey of 143 people and Ethnography. Based on this, we propose an app service that helps practice the right posture by using EMG sensors and wearable devices. This study is meaningful in alleviating musculoskeletal pain and further improving the quality of life by helping to practice and maintain the right posture with service content based on self-objectification through user posture habit analysis.

최근 고화질 영상의 수요가 증가함에 따라, UHD급 디스플레이의 디지털 기기가 등장하기 시작했다. 하지만 기존의 스케일러 모듈에 사용된 보간법들로는 기존의 저해상도의 영상 콘텐츠로부터 고품질의 영상을 획득하기가 어렵다. 따라서 본 논문에서는 고품질의 영상을 획득 가능한 초고해상도 영상에 적합한 스케일러를 제안한다.
