Tencent is an internet-based entertainment platform corporation using technology to enrich the lives of Tencent platform users and assist the contents expansion. Since 2000, Tencent have developed a great growth and innovation in entertainment contents domain. Tencent have become the market leading innovator due to the imitative innovation and M&A. The present study designed case study analyses to investigate the mechanism with regard to the growth strategy of Tencent corporation. Tencent began with imitative internet-based game and social messaging services but then added its own wechat messenger platform, now being extended to other products or services. This imitative innovation strategy enabled Tencent corporation to grow rapidly, to achieve outstanding growth. In addition, Tencent's M&A investment drive is underpinned by a vision of top management team and flexible organizational culture, from building out the Tencent's entertainment platform, game, finance, e-commerce, to global market expansion. While our results shed light on the implications to understanding Tencent's growth, there are limitations of the current study that should be considered when designing next research.

최근 주요 이동통신 사업자, 단말기/칩 제조업체, 콘텐츠 제공업자들 사이에는 모바일 3D 분야가 가장 큰 이슈로 떠오르고 있다. 이러한 환경을 기반으로 모바일 장치에서 3차원 아바타 애니메이션 연구가 진행되고 있다. 이는 아바타의 자연스러운 동작은 사용자에게 아바타가 살아있는 듯한 느낌(Life-likeness)과 사실감(Believability)을 심어주어 보다 친숙한 인터페이스로 활용될 수 있고 이에 따라 채팅이나 온라인 게임 외에도 교육, 쇼핑몰, 비즈니스 등 다양한 분야로 확대되고 있기 때문이다. 하지만 지금까지의 연구는 자연스러운 모션 생성에 집중되어 있을 뿐, 어떻게 쉽게 아바타는 제어할 것 인가에 대한 연구가 적었다. 특히 모바일 환경에서 효율적인 아바타 동작 제어를 위한 연구는 부족하다 할 수 있다. 본 논문에서는 모바일 환경에서 효율적인 아바타 동작을 제어를 위해 스크립트(Script) 기반의 아바타 동작 제어 기법을 제안한다. 모션 생성을 위해 아바타 동작 스크립트(Avatar Motion Script)를 정의하여 아바타 애니메이션의 기록, 재생이 가능하다. 둘째 계층적 스크립트(Multi-Level Script) 기법을 이용하여 적은 양의 데이터만으로도 아바타 동작 제어가 가능하다. 셋째 어느 환경에서도 Motion이 생성, 재생이 가능하한 플랫폼 독립적 구조이다. 넷째, 키 프레임(Key Frame) 기반의 모션을 이용하여 아바타의 상황 상황에 모션이 변하는 동적 동작 생성이 가능하다.

Motion capture devices have been utilized in producing several contents, such as movies and video games. However, since motion capture devices are expensive and inconvenient to use, motions segmented from captured data was recycled and synthesized to utilize it in another contents, but the motions were generally segmented by contents producers in manual. Therefore, automatic motion segmentation is recently getting a lot of attentions. Previous approaches are divided into on-line and off-line, where ow line approaches segment motions based on similarities between neighboring frames and off-line approaches segment motions by capturing the global characteristics in feature space. In this paper, we propose a graph-based high-level motion segmentation method. Since high-level motions consist of repeated frames within temporal distances, we consider similarities between neighboring frames as well as all similarities among all frames within the temporal distance. This is achieved by constructing a graph, where each vertex represents a frame and the edges between the frames are weighted by their similarity. Then, normalized cuts algorithm is used to partition the constructed graph into several sub-graphs by globally finding minimum cuts. In the experiments, the results using the proposed method showed better performance than PCA-based method in on-line and GMM-based method in off-line, as the proposed method globally segment motions from the graph constructed based similarities between neighboring frames as well as similarities among all frames within temporal distances.

Due to spread of movies or online games which are applied with computer animation techniques, we can easily see scenes where numerous characters appear. In the case of large-scale crowd animation, if one were to increase reality of the scene, features of system would be lowered, and if one were to increase functioning of system, reality of the scene would be lowered. In realizing large-scale crowd animation with seafloor environment as background, the paper analyzed and applied elements that affect behavioral types of fishes; and by using concept of crowd, the paper enabled each group or object to control their behavioral type; by comparing and contrasting real-time calculation method as calculation method for animation and hybrid calculation method which is mixed calculation method, the paper seeks to find a method that increases functioning of the system while also expresses natural scenes.

In this study, we examine other factors that may contribute to the decline in students' academic performance and educational attainment. Many media reports, as well as previous studies, have suggested that virtual learning is the main reason for the decline in students' academic performance. However, the 2020 National Student Achievement Survey, which was conducted in conjunction with the COVID-19 Distance Learning Environment Student Survey, showed that students were highly satisfied with distance learning (70-80%), and the analysis of the National Assessment of Educational Achievement showed that students' academic performance had already been declining year by year since 2017, with a general downward curve. For further confirmation, we analyzed the performance of high school students on mock exams and found that their performance was not normally distributed, but rather a right-skewed U-shaped distribution with a shrinking number of medians and severe polarization. We found that this phenomenon is not simply because of the mode or quality of the virtual classroom, but to a variety of factors, including environmental influences such as care and management at home, changes in investment in private education, increased time spent on online devices while taking virtual classes at the bottom, and increased time spent watching online content, games, and videos that are not related to learning.
