Recently, tourism and leisure related VR contents have gained attention of potential tourists. Therefore, this study aimed to analyze investigate the effects of 360-degree VR tourism contents motivations, flow, continuance usage intention on visit intention for Chinese student in Korea. This study found that hedonic benefit and personal benefit exerted a positive influence on visit intention of contents users. However, vividness and usability did not influence on visit intention. Moreover, flow exerted a significant influence on visit intention but continuance usage intention did not influence on visit intention. The study is significant in shedding light on whether the motivations, flow, continuance usage intention of 360-degree VR tourism contents influences visit intention. It is suggested that the consumption of 360-degree VR tourism contents can be a useful marketing tool for strength of intention to visit.

대용량 모바일 기기의 발전과 보급이 확산됨에 따라 사용자들은 사진, 음악, 동영상과 같은 멀티미디어 콘텐츠를 대량으로 휴대하며 이용할 수 있게 되었다. 그러나, 이러한 대량의 멀티미디어 콘텐츠 관리는 사용자 각자에게 맡겨져 있어 콘텐츠 관리를 어렵게 하고 있는 현실이다. 본 논문에서는 분산 모바일 환경에서 멀티미디어 콘텐츠의 공유와 추전을 통해 사용자에게 적합한 콘텐츠를 추천을 통해 제공하고, 제공된 콘텐츠는 모바일 동기화 서비스를 통해 모바일 기기로 저장하고 관리되는 '분산 모바일 환경에서 멀티미디어 콘텐츠 추전 및 검색 서비스'를 설계하고 구현하였다. 제안된 시스템은 사용자의 선호 프로파일 정보로 협업 필터링을 통해 공유된 멀티미디어 콘텐츠 중에서 사용자에게 적합한 콘텐츠를 추천해 주고, 추천된 콘텐츠는 모바일 기기 사용자의 행동에 따라 모바일 동기화 서비스를 통해 모바일 기기에 저장과 관리, 검색이 된다. 본 논문에서 제안된 방법은 추천과 검색을 통해 사용자 모바일 기기의 멀티미디어 콘텐츠를 효율적으로 관리 할 수 있다. 이처럼 본 논문에서 제안된 서비스 방법은 멀티미디어 콘텐츠의 추천과 모바일 동기화 서비스로 능동적인 콘텐츠 관리를 제공하며, 사용자에게 효율적인 콘텐츠 검색 기법과 활용 방법을 제공 할 수 있다.

The learners using learning content through the smart devices can access to the Internet from anytime and anywhere. However, with the rapid increase of learning content on the Web, it will be time-consuming for learners to find contents they really want to and need to study. Therefore, e-learning systems should not only provide flexible content delivery, but support adaptive harmonizing fusion content. The harmonizing fusion content it is a very important in fusion e-learning service. The representative method to provide synchronization between fusion content is a provide absolute time value between of the contents. However, this method is occurs a problem transferring time delay. Also, to enter an absolute time value for the duration of the each content is several problems arise. In this paper introduces a new smart e-smart service support the harmonizing media based technology to create synchronized learning presentation.

Artificial intelligent (AI) smart speaker sales have increased rapidly, and AI technology has become more pervasive in our daily lives. This study explored motivations for smart speaker use and examined how motivation and relationship type with AI speakers affect enjoyment. Smart speaker use is primarily motivated by conversational, trend-leading, efficient, and entertaining factors. Among these four, trend-leading, efficient, and entertaining factors positively influenced users' enjoyment. However, among the three types of relationship with AI speakers, only the assistant/helper type affected enjoyment. The results of the current study provide practical implications for future directions in AI speaker interaction design.

와이브로(Wibro) 또는 WiFI 망에서 동일한 멀티캐스트 그룹에 속한 이동 단말기들은 동일한 MBS(멀티캐스트/브로드캐스트 방송 서비스) 콘텐츠를 수신한다. 동일한 MBS 존 내의 기지국(RAS: Radio Access Station) 들이 MBS 콘텐츠 소스로부터 수신된 MBS 콘텐츠에 대한 전송 시간을 동기화할 수 있도록 기지국들은 전송 동기화 정보와 신뢰성 있는 데이터 패킷 수신을 동기 시간을 결정하기 이전에 보장받을 수 있어야 한다. 만약에 동일한 MBS 존에 속하는 다수의 기지국 중에 전송 동기화 정보를 수신하지 못하거나 패킷 데이터 일부 또는 전부를 수신하지 못한다면, 동기 전송 시간을 결정하기 전에 이미 손실된 정보와 패킷 데이터를 이동 단말기로 전송하게 됨으로써 이동 단말기가 MBS 콘텐츠를 수신하면서 동일 MBS 존 내의 다른 기지국으로 핸드오버하게 되면 MBS 콘텐츠에 대한 끊김없는 수신을 보장할 수 없을 뿐만 아니라 매크로 다이버시티(macro diversity) 이득을 얻기 위한 동일한 MBS 존에서 이동 단말기들에게 전송되는 MBS 콘텐츠들의 동기를 보장 할 수 없다. 따라서, 본 논문에서는 동기 전송 시간을 결정하기 앞서서 다수의 RAS가 전송 동기화 정보와 신뢰성 있는 패킷 데이터 콘텐츠 수신을 보장받을 수 있는 장치를 보완한 멀티캐스트/브로드캐스트 서비스 데이터 전송 동기화 방법을 제안한다.

With the growth of information technology, people consume online video contents via mobile phone without time and location constraints. Drawing upon uses and gratification theory, this study examines the effects of usage motives and affinity on user activities on YouTube. Specifically, user activities are subdivided into pre-viewing and during-viewing activities in this study. Results show that convenient entertainment and social interaction are the significant indicators for pre-viewing activities, whereas five different motives significantly influence during-viewing activities. Furthermore, affinity is the significant determinant of the both activities. The theoretical and practical implications are also discussed.

By integrating of intrinsic motivation theory and flow theory, this study sought to investigate the causal linkage among optimal balance of video game player's perceived skill and challenge, flow experience, intrinsic motivation and video game genre usage. A path analysis showed that the different types of video game usage were directly influenced by players' intrinsic motivations, which were also reinforced by players' flow experiences of enjoyment. However, the path model with a multiple group approach provided no strong evidence for gender differences in the relationships between the variables of interest.

Recently various handheld multimedia devices are spreading, and users want to share media contents across their own multiple devices. Conventional synchronization techniques for N-screen services can continuously play contents by switching from an initial device to a new device. In this case, even if a new device plays continuously contents, the initial device stops playing them. In this paper, we propose a synchronization technique in which multiple devices can share and continuously play same contents simultaneously by gathering and passing URI and current play-time of the contents. The proposed synchronization technique is built on UPnP and DLNA, and tested by implementing a wireless home media network system.

The purpose of this study is to investigate the causes of pre-roll ads played before watching online video contents, and to investigate the using motives by dividing them into broadcasting contents clips and web original contents. The results show that broadcast contents clips have higher use of entertainment/habitual use and social interaction, and that the use time of web content is higher when entertainment/convenience and selective use motivation are higher. Second, perceived invasion has the greatest effect on ad avoidance in broadcasting contents clip, and positive attitude toward advertisement is a significant factor in web contents. Content factors such as content preference and engagement did not affect the avoidance of pre-roll ad.

In this study, we examined the motivations of using Kakaotalk's gift that is one of services provided by Kakaotalk, the most popular mobile-based messenger. We also investigated possible effects of these motivations on the satisfaction of the Kakaotalk's service and a potential association of these motivations with the frequency of purchasing gifts using the service. In order to answer the research questions, we conducted a survey that recruited 220 users ranging from teenagers to in forties. As the main results of analysis, we identified four different types of user's motivations for Kakaotalk's gift: beneficial motivation, convenient motivation, improvised buying motivation, and entertaining motivation. Both the beneficial motivation and the entertaining motivation were significantly associated with the gratification of using Kakaotalk's gift, which was in turn significantly associated with the frequency of purchasing gifts through the service.
