The paper's suggestion is Web based Tele-Medicine System will be open to public, low-budget featuring high quality of extensive medical services. It will keep a log of personal medical history to allow doctors to share information on patients and their families. This will result in the reduction of erroneous diagnosis and ensure successful e-business. On top of this, the new system will provide a solution for membership (client) management. It will combine online and offline medical services and be available 24 hours a day to anywhere users have Internet access, setting itself apart from the existing distance medical services system. Specially, The paper's suggestion is sharing medical treatment information between family members is suggested. This approach makes possible understanding physical constitution and environment between family members, and can result in bringing a faster treatment effect if some family member suffers from a similar disease.

The rapid use of Facebook among colleges, the present study was to explore the motivations of college owned Facebook among college students. The factor analysis The factor analysis showed that the college students perceived that the intimacy, update of college information, sharing daily lives, use of time, seeking useful information are important motivations when they use college Facebook. The extracted factors such as emotional intimacy, information update and sharing daily lives also play significant variables to affect Facebook effectiveness such as "like" and "sharing others." The results suggest that Facebook managers need to use college Facebook as a social medium not by one way communication medium to the college students.

Social Media is the open online tool and media platform for sharing and participation of users opinion, experience, viewpoiont, so general situation that is one-side flowing from production to consume doesn't act, and while use of two-way, user create contents use of sharing and participation. This social media include Blog, Social Network Service(SNS), Wiki, User Create Contents(UCC), Micro Blog, 5 types. In broad terms, Social Learning is self-learning that user sharing with coperation and collective intelligence through Social Media, and in few wards Social Learning is learning for Social Media. In this research, we define Social Media and Social Learning, and research of method of use of Elementary Education.

With rapid growth of content demands, device-to-device (D2D) content sharing is exploited to effectively improve the service quality of users. Considering the limited storage space and various content demands of users, caching schemes are significant. However, most of them ignore the influence of the asynchronous content reuse and the selfishness of users. In this work, the user preferences are defined by exploiting the user-oriented content popularity and the current caching situation, and further, we propose the social-aware rate, which comprehensively reflects the achievable contents download rate affected by the social ties, the caching indicators, and the user preferences. Guided by this, we model the collaborative caching problem by making a trade-off between the redundancy of caching contents and the cache hit ratio, with the goal of maximizing the sum of social-aware rate over the constraint of limited storage space. Due to its intractability, it is computationally reduced to the maximization of a monotone submodular function, subject to a matroid constraint. Subsequently, two social-aware collaborative caching algorithms are designed by leveraging the standard and continuous greedy algorithms respectively, which are proved to achieve different approximation ratios in unequal polynomial-time. We present the simulation results to illustrate the performance of our schemes.

This paper explains the design and implementation of the EC_NH. EC_NH is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share error applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participants engaged in a cooperative work. Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others.

As internet is getting advanced day by day, digital contents have been developed in various areas as killer content in the IT industry. It needs to develop lots of complicated digital content protect systems due to the enhancement and variety of user's multimedia devices. Although there are lots of protect systems based on DRM(Digital Rights Management) technology, it is difficult to provide secure protection because of the problems resulting from analog hole problem, inefficiency of key sharing and various independent protect technologies. Thus, in this paper, we propose a novel authentication and protect system based on RFID(Radio Frequency Identification) technology to solve the problems and show possibility of free content duplication and efficient contents management in smart home environments.

With the coming of information times, digital contents are widely applied in various fields of the society. Along with this, scholars provided many techniques and research approaches related to digital contents management and copyright protection. But till now, most proposed techniques and approaches are based on single system. The independency and separation among management systems causes the problems such as application across systems are limited, and resources sharing can't be available, etc. In this paper, for the application cross systems and contents sharing, we propose the cross-systems DRM approach based on unified metadata. This approach can be applied for the incorporation of multiple congeneric or heterogeneous CMSs, in the same time, solve the copyright problem cross digital content systems.

The purpose of this study is to examine the roles of emotional intelligence and knowledge sharing, while focusing on the customer orientation of flight attendants, to identify the strategies to improve the quality of services provided by flight attendants. For this purpose, the researcher examined the relationships between emotional intelligence and customer orientation, as well as the impact of knowledge sharing in the process. The survey was conducted over three weeks from May 6, 2021, to May 27, 2021, and the 426 questionnaires recovered were analyzed using statistical software programs SPSS 23.0 and AMOS 23.0. The findings of this study are as follows; First, the emotional intelligence of flight attendants had a positive impact on customer orientation. Second, the emotional intelligence of flight attendants had a positive impact on knowledge sharing. Third, the knowledge sharing of flight attendants had a positive impact on customer orientation. Fourth, in the relationship between the emotional intelligence of flight attendants and their customer orientation, knowledge sharing had a significant mediating effect. Based on the findings of this study, it would be possible to consider support strategies for organizations, including the training programs for enhancing the emotional intelligence of flight attendants and a corporate culture in which knowledge sharing can be promoted.

This study was conducted to examine the effect of the characteristics of branded contents on consumers. To attain the purpose of the study, we carried out a survey with 286 male and female undergraduates and collected data for analysis. The findings demonstrated the followings: First, the satisfaction of using branded contents is positively affected by entertaining, empathy, creativity, and indirectness. Second, the intention to share branded contents and the intention for continuous use of them are positively affected by entertaining only. In conclusion, this study confirmed that only informativeness, which is one of 5 characteristics of branded contents, does not have any effect on the consumer. This result provides useful empirical data for developing high-quality contents that meet user's needs and convenience, helping understand user's behavior toward branded contents and also serves as the basic data on which related researches can expand.
