With the development of AI, multimedia tools in education offer personalized learning environments, which foster individual competencies. This study aims to examine the effectiveness of smart education as perceived by learners through a case study of university writing classes utilizing multimedia learning tools, and to explore potential applications. To achieve this, a writing course incorporating various multimedia tools to promote interaction was designed and implemented over the course of one semester, targeting 42 university students. Through the semester, student reactions and survey results were analyzed to investigate the effects and satisfaction levels regarding the use of multimedia learning tools in writing instruction as perceived by students. The analysis revealed that multimedia-assisted writing classes effectively fostered learners' autonomy by focusing on individual needs, while also promoting interaction and encouraging spontaneous participation. Students reported recognizing the presence of diverse perspectives by comparing and communicating about each other's writing, leading to an expansion of their own thinking. In using ChatGPT, it was found that students attempted to refine their questions until they obtained the desired answers. They reported that this process deepened their understanding of the essence of the questions. These benefits led to results of high levels of students' active class engagement and satisfaction. This study contributes foundational and empirical data regarding the effectiveness and potential applications of learner-centered smart education as part of fourth industrial revolution integration research.

This study identifies the key determinants and technology innovation adoption type of participation in multimedia UCC services. This research examines how the major factors of perceived usability, self-expression, fun & entertainment, arousal, information sharing, other's positive reputation and interface easiness contribute to participation in multimedia UCC services. A sample survey of internet users was conducted, responses were collected from 629 respondents and consumer streaming data were analyzed. Some of the practical implications of the results are follows. This research have categorized that the types of technology adoption for the participation of UCC were innovator consumer, early adaptor consumer, early majority consumer, and late majority consumer. The results of multiple regression analysis indicated that perceived usability, interface easiness, fun & entertainment, self-expression, arousal, other's positive reputation and type of technology adoption posited a significant effect in multimedia UCC Services.

최근 여성이나 아동, 장애인 등의 사회적 약자를 대상으로 하는 흉악 범죄의 빈도수가 늘어나면서, 사회적 불안감이 점점 높아지고 있다. 이러한 사회적 불안감을 줄이고, 안전보장에 대한 요구를 충족하고자 기업체와 관련 정부기관에서는 국민의 안전보장 대책들을 내놓고 있다. 스마트기기에서의 GPS 등을 활용한 위치정보의 정확성이 날로 높아지고, 이에 기반을 둔 위치기반서비스의 발전에 힘입어, 이에 대한 대책 중 하나로 개인위치정보에 기반을 둔 개인 안전 서비스와 시스템을 다양하게 제시하고 있다. 본 논문에서는 현재 시중에서 이용되고 있는 각 개인 안전 서비스 및 어플리케이션을 분석하였다.

This study aims to clarify the nature and properties of multimedia interface design, and to identify direction of multimedia interface design research. It also focuses on forecasting boundaries and major trends in current researches on multimedia interface design. The two jargons, 'interface' and 'interaction', are distinguished clearly to show the definition and boundary of multimedia interface. The multidisciplinary nature of multimedia interface design is identified as a result of examination and analysis on major researches. Nine research cases have been selected and categorized into two directions as the theoretical approach and the technical approach. Major characteristics of each case are examined in terms of subjects and methodologies. Findings on current states of the multimedia interface design research are: $\circled1$increasing importance of contextuality; $\circled2$emerging tendency for perceiving the content as one of interacting subjects; $\circled3$providing idiomatic interface context; and $\circled4$paying much attention to the meaning of minor actions. Those findings can be possible as a result of expansion of boundary of multimedia content with rapid distribution of multimedia in recent years. The study concludes that further researches can be activated on the basis of the concept of content-based multimedia interface.

In this paper, we propose a multimedia hardware architecture for desktop video-conferencing in view of the multimedia data flow and analyze system operation using queueing model. We analyze the bottleneck of multimedia data flow for video- conferencing by simulation, varying the video size, frame rate, the number of participants, and video data compression rate, And we also implement and test the archiecture, that almost includes the analyzed requirements for video-conferencing, to confirm the simulation results. This paper describes the considerations in designing a multimedia I/O system.

This paper provides a state-of-the-art on multimedia metadata. After a brief introduction to multimedia metadata, the paper described and analyzed the main metadata initiatives. The results show that these initiatives described the bibliographic elements rather than metadata for contents representation. On the other hand, MPEG-7 covers a rich and detail aspects for representing the complete and consistent multimedia content.
