E-commerce live broadcast is a new online shopping model that has gradually emerged in China in recent years. In the e-commerce live broadcast, the audience gathered into a buying group by watching and participating in virtual interaction, and obtained stable emotional energy from it. Closely following the concept of emotional energy, with the help of the interaction ritual chain model, the components of e-commerce live broadcast can be clarified. And the paper shows how individuals can form a buying group in social interaction. I will take the interaction behavior in e-commerce live broadcast as the research object and observe the phenomenon based on the theory of interaction ritual, then come up with the interaction ritual chain model of E-commerce live broadcast group.

MPEG에서는 빠르게 급변하는 시장의 요구를 충족시키기 위해, 기존의 긴 시간이 요구되는 표준화 방식과 달리, 서로 다른 기존 규격들을 특정 응용 서비스의 목적에 맞도록 조합해 하나의 표준으로 규격화하여 'MPEG-A(MPEG-Applications: ISO/IEC 23000) 멀티미디어 응용 표준'이라는 명칭으로 표준화 활동을 활발히 진행하고 있다. 본 논문에서는 2007년 10월 중국 신천에서 개최된 제 82차 MPEG회의에서 작업 표준안(Working Draft)으로 채택되어, 2008년 10월 부산에서 개최된 86차 MPEG회의에서 최종 국제표준 초안 (final draft international standard) 으로 승인된 스테레오스코픽 비디오 응용 포맷(Stereoscopic Video Application Format) 기술을 소개하고자 한다. 스테레오스코픽 비디오 응용 포맷은 현재 시장에 등장하여 점차 수요가 증가하고 있는 스테레오스코픽 카메라, 디스플레이, 모바일 단말 등의 장치를 이용한 스테레오스코픽 영상의 획득과 출력 서비스를 위한 요구사항 및 저장규격을 정의한다. 이러한 기술을 활용하여 기존의 특정 장치에서만 획득 및 출력이 가능했던 폐쇄적 서비스에서 벗어나, 스테레오스코픽 콘텐츠의 저장 및 사용자간 교환, 방송, 리치미디어 서비스에서의 활용 등과 같이 3차원 입체영상 콘텐츠의 활용도를 높일 수 있을 것으로 기대된다.

Currently, in China, mobile live broadcasts are more popular compared to online live broadcasts. Accordingly, this research focused on Wanghong, SNS's flagship live broadcasting app. In other words, Wanghong refers to an internet celebrity who acts online on social network services (SNS) influencing many other people. This study specifically focused on one social network service and conducted a study on live app users. The study first analyzed the quality factors of an SNS to users using China's live app. Secondly, the research investigated in finding out the impact of quality on the satisfaction of live app users and how this affects the live app user's satisfaction on their intention of continuous use. Studies have shown that information quality, system quality, and social quality among SNS quality have a positive influence on live app user satisfaction. However, the quality of service and the quality of emotion was rejected by the hypothesis. Throughout this study, we hope to create an app that allows users to share more satisfying mobile images, thereby establishing various episodes holding beautiful places of their life on a real-time basis. It is hoped that live broadcasting businesses will spread a significant impact around the world. Finally, in the future, research on the study of collective comparison between Korea and China on SNS is believed to be meaningful.

The emergence of knowledge-sharing live streamers provides more diversified content to the live streaming platform. Analysis of the factors affecting the intention to use knowledge sharing live streaming users can allow the live streaming platform to understand better the adoption characteristics of users who follow this type of content. Help platform operators provide better services and help live streaming platforms innovate. Based on the TAM model, this research uses questionnaire surveys and structural equation models to construct a conceptual model of the influencing factors of users' intentions in the knowledge sharing live streaming and conduct an empirical analysis on the influencing factor models. The results of data analysis show that a significant influence of users' attitudes of knowledge sharing live streaming is perceived usefulness, followed by flow experience; perceived value has a positive impact on users' attitudes and intention to use, and the positive influence of users attitude significantly affect the user's intention.

Currently, CMMB(China Mobile Multimedia Broadcasting) and the conventional analog TV broadcasting have transmitted by using UHF(Ultra High Frequency : 474MHz~754MHz) band. Normally, the transmission power of the digital TV broadcasting is lower than the conventional analog TV broadcasting to protect the reception quality of the conventional analog TV broadcasting. The reception sensitivity of CMMB receiver has severely deteriorated due to adjacent the conventional analog TV broadcasting signals which called ACI (Adjacent Channel Interference). To improve the reception sensitivity of a CMMB receiver on ACI environment, this paper proposed a simple method which is tuning a cut off frequency of LPF (Low Pass Filter). From the experiment, the reception sensitivity of CMMB receiver was improved as 11.3dB.

This study explores diffusion of information on Covid-19 relating to China on You Tube. For this, information on Covid-19 relating to China was divided into factual information and disinformation, with factual information being categorized into positive and negative information. According to network analysis, there are lots of negative information and disinformation. On the contrary positive information is rare. There are lots of videos about rumor on the leak of Wuhan institute among disinformation. Rumor on the manipulation of genes has the highest average value of view count and betweenness centrality. Main stream youtube channel has only role of messenger which delivers messages as it is instead of fact-checking on disinformation. The fact which there are much more negative information or disinformation among videos about Covid-19 relating with China shows that Youtube users skewed toward negative information and disinformation than positive ones. In summary, disinformation on youtube brings spreadable effect by making user watch similar contents.

Jinling University during the Republic of China (1912-1949) is the most representative academic institution in film education and filmscience, film production, film distribution and many other aspects. Although Jinling University had not yet formed an independent animation discipline, the opening of its animation curriculum, theoretical research, and the practice and production of animation have played an important historical role in the development of Chinese animation and are the beginning of China's animation education. This study investigates Jinling University comprehensively and systematically reviews the forms of animation education. At the same time, macroscopical education and microcosmic education concepts are used to analyze the social context of the Republic of China of discipline construction and external education concept at that time. It sketches the historical clues of the development of animation education in Jinling University in the Republic of China, and lays the foundation for further studying animation education in the Republic of China in theory.

군사용으로 먼저 개발되어 시장을 형성했지만, 드론의 제작이 많아지면서 소비자 시장이 급속도로 확대되고 있다. 최근 중국의 DJI는 기업가치 100억 달러 이상을 넘볼 정도로 급성장 하였고, 드론용 소프트웨어나 플랫폼을 확보한 스타트업 기업들에 대한 투자도 활발하게 진행중이다. 구글이나 페이스북, 아마존 등 자사의 서비스 강화를 위한 목적으로 드론 기술을 적극적으로 활용하고 있으며, 드론의 시장 확대에 따른 드론 시장 생태계도 크게 확장하고 있다. 향후 민간용 드론 시대가 도래 할 것이라고 예상하고 있다. 이에 맞춰, 본 논문에서는 민간용 드론의 국내 외 활용사례 중심으로 살펴보고, 민간용 드론 시대를 대비하여 국내 대응 방안을 제시해보고자 한다.
