The development of the digital compression technology and the broadcasting receiver's processing power make it possible to apply a multi-view function to the broadcasting services. The multi-view function is usually utilized to provide simultaneously several programs to viewers or to implement a multi-angle service of a sports program that allows a viewer to choose a video of his/her prefer viewpoint. The paper proposes an integrated method for utilizing a multi-view function in the digital broadcasting environment in which more than 100 programs are on air and there may be various data services which want to use multi-view video clips. For the purpose, a method of composing and transmitting multi-view videos and related information has been devised and a Java API to utilize the rapid editing function of a decoding chip-set has been implemented to clip, resize, and display parts of the multi-view videos.

Digital technology is progressively transforming rural education and offering unprecedented opportunities for advancement. This study aims to analyze the impact of digital technology on rural education, focusing on the usage of digital resources in Wencheng County, Zhejiang Province, as a case study. The primary objective of this research is to explore how the application of digital technology contributes to balanced educational development in rural areas and to identify the key challenges and issues that accompany such technological advancements. The study revealed several significant issues in Wencheng County's rural education system, including inefficient use of digital resources, inadequate digital skills among educators, and insufficient exploration of digital innovation. In particular, the redundant purchasing of digital educational resources and the inefficient utilization of these resources, coupled with the low adaptability of teachers to digital technologies, emerged as major concerns. The study proposes strategies to address these issues. Ultimately, it presents an optimized pathway for successfully implementing digitalization in rural education and offers policy insights that could be applied in other regions to achieve similar improvements.

The advent of the 4th industrial technology brought about various changes and innovations in the overall industry, but the digitalization of the logistics industry, which involved complicated paperwork processes and various stakeholders, was somewhat behind compared to other industries. However, changes and innovations related to digitalization in the logistics industry began to accelerate due to the impact of COVID-19. This study is to check the digitalization status of container liners accelerated by these changes, analyze the impact of such changes on customer satisfaction and behavioral intention. In this study, a questionnaire survey was conducted for 30 days targeting workers in the logistics industry who had experience using digitalization products of container shipping companies, and a total of 144 questionnaire responses were used to verify hypotheses. To summarize the results of this study, first, it was confirmed that perceived ease of use has a positive (+) effect on perceived usefulness. Second, perceived ease of use was found to have a positive (+) effect on customer satisfaction. Third, it was found that perceived usefulness had a positive (+) effect on customer satisfaction. Fourth, perceived usefulness has a positive (+) effect on behavioral intention. Fifth, it was found that customer satisfaction had a positive (+) effect on behavioral intention. Summarizing the results of the study, it can be summarized that the digitization of regular shipping companies is convenient to use and has a positive effect on customer satisfaction and behavioral intention if it is useful.

새 천년을 여는 이 시대의 화두는 인터넷과 디지털이라 해도 과언이 아닐 것이다. 이에 발맞추어 디지털을 치과 임상에 적용하고자 하는 많은 시도들이 있으며, 특히 치과 방사선 분야에서 다양한 결과들을 실제 임상에서 많이 이용하고 있다. 또한 많은 임상의들이 디지털 카메라를 이용하여 임상사진을 체득하고 활용하려는 시도들을 많이 하고 이용하고 있으나, 디지털 카메라에 대한 정확한 이해 없이 일반 광학 카메라와 동일시 하는 생각으로 수많은 시행착오를 겪고 결국 애써 장만한 디지털 카메라를 사장시키거나 제대로 이용하지 못하는 경우들을 주위에서 많이 보아왔다. 필자도 처음 디지털 카메라를 장만하였을 때 많은 실행착오와 좌절을 경험했지만, 그 동안 수집한 정보를 비교 분석해서 얻어낸 결과와 실제 촬영을 통해 완성시킨 다양한 테크닉을 중심으로 이 글을 서술한다. 디지털 카메라를 소장하고 있거나 구입 의향이 있는 분들에게 유용한 정보가 되기를 바라면 6월과 7월 2회에 걸쳐 본 글을 게재한다.

디지털 문화재 콘텐츠는 현실에서 체험하기 힘든 문화재를 디지털 기술의 특성을 이용하여 사용자의 경험을 극대화할 수 있고, 문화재 보수, 교육 등에 활용될 수 있다. 그런데 기존의 디지털 건축물 문화재는 실재 문화재의 구조 및 구성을 무시하고 외형만 만들어져 있어서 다양한 형태로 바꾸어 활용하기 곤란하며, 디지털 건축물 문화재 자체가 가상공간에 존재하여 현실체험에 제한을 받고 있다. 본 논문은 사용자가 현실공간에서 부재 미니어처를 이용하여 미니어처 문화재를 조립하고 그 결과를 가상공간의 디지털 문화재로 연결하여 다양한 체험을 제공하는 시스템에 관한 것이다. 이로서 현실 체험과 가상 체험이 연결되어, 보다 효과적인 체험이 가능하고 건축 문화재에 대한 보다 전문적인 학습이 가능하게 된다.

Diagrams have been deeply and widely used for supporting effective communication relating to design information and knowledge in most design fields. The results show that their role expands to "developmental design material" increasing the principle and method of design process. It's recent trend that Digital-Diagrams are aggressively used in multimedia design fields such as web contents, interactive movies and DVD Titles in order to support user's information understanding more effectively and to stimulate user's participation in information acquiring process. This study aims to clarify the essence of digital diagram corresponding to infographic material in multimedia design and application of multimedia contents development process . This study purpose leads to argue the substance of Digital-Diagrams as one of infographic types and identity of Digital-Diagrams which is relatively compared to existing Diagrams. Eventually, this study examines the application issues of Digital-Diagrams in multimedia design process. Regarding the identity of Digital-Diagrams, they are functionally utilized depending on hypertext based on language forms and interactivity based on graphical forms as core attributes. Therefore, they semantically enlarge user s information understanding by segmenting hierarchy of information expression and rather support user s acquisition of information control ability. Relating to multimedia design process, Digital-Diagrams are used by information designers and navigation designers as method for ‘modeling for realization based on information acquisition support for information-users. Especially, the study results show that the applications of Digital-Diagrams are performed for information representing methods for information designers and embodiment of useful functional factors of interface for navigation designersgation designers.

The purpose of this study is to analyze the influence of digital textbook use for potential risk group of internet addiction and average group. For this, I selected two samples. One was a group to use digital textbook at school, the other was a group not to use that. Then each potential risk group of internet addiction were sort out in two groups by a test of internet addiction. I firstly compared a average user group and a potential risk group of internet addiction in group to use digital textbook. Also, I too did that in group not to use digital textbook. Then I analyzed the relevance of using digital textbook and internet addiction. As a result, I found that using digital textbook have not the relevance with internet addiction. But in this paper, I proposed a way to teach ICT ethical training before students use the digital textbook, because most of potential risk students of internet addiction tend to think they was influenced by digital textbook.
