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 the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.

집단에 의해 자유롭게 생성되는 데이터 중 댓글을 활용하여 수익을 내려는 포털사이트들이 증가하고 있는 추세이며, 물건이나 콘텐츠에 대한 사용 후기를 바탕으로 평가하는데 있어서 품질이 높을 때와 낮을 때, 사용 후기의 유효성과 신뢰성 판단이 달라진다. 그만큼 댓글은 중요하게 다뤄지고 있다. 본 연구에서는 동영상콘텐츠로부터 추출된 댓글을 활용하여 긍정적인 감성어휘와 부정적인 감성어휘 그리고 강조 감성어휘를 도출하여 평가가 높은 동영상 콘텐츠를 추천하는 모델을 설계하고자 한다.

In this paper, we proposed a mechanism that prevents indiscreet use of digital contents, verifies created content's copyrights to provide services to granted user and protects digital contents by law by authenticating the original digital content whenever an infringement of copyright occurs in UCC environments. The proposed mechanism uses specific information and features of contents as copyrights authentication information without additional information. Also, provides the fact of violation by inferring the modification of the original digital contents. That means this mechanism infers same or similar value from the contents; fraudulent use of content, modification of content color, modification of content format, modification of content resolution and illegal use of frame not principal key frame. In that point, we found that the inferred value from the content differed according to features of content modification.

대중화된 소셜 네트워크 환경에서 사용자가 제작한 콘텐츠를 빠르고 간편하게 공유할 수 있도록 하는 모바일 App을 개발하였다. 기존 사용자 영상 콘텐츠 제작 환경에서는 필요 이상의 소음과 잡음이 혼재하여 영상에서 풍기는 이미지의 감동을 저해하고 있다. 이러한 주의의 소음과 잡음으로부터 영상을 보호하도록 배경음악을 영상과 함께 재생하여 영상의 감동과 느낌을 사용자에게 전달하기 위한 App이다. 또한 소셜 네트워크 환경에 간편하게 업로드 할 수 있도록 페이스북을 통해 다른 사용자와 빠른 공유를 할 수 있다.

The demand of digital broadcasting via networks has increased slowly in spite of the development of bidirectional broadcasting service technology and the effort of revitalization are actively performed nowadays. There are some reasons that the content differentiation is necessary. First, bidirectional digital broadcasting has no special content that attracts public attention. Second, bidirectional video content such as UCC is expected to revitalize economy due to simplification of authoring tool and user's desire to communicate interactively. So this paper proposes the data broadcasting sub-content architecture model by scenario using original data broadcasting content. At the same time, we design the content object metadata schema from the analysis of original data broadcasting content. It is restricted by 25 metadata in order to make it more smoothly working contents under the ubiquitous environment. This proposal is expected to affect the revitalization of content development and find out new sub-content model by rework original content.

As the mobile internet rapidly progress and mobile terminals are activated, business entities which want to operate mobile web contents and individuals who want to use it increase. 6005plus.com as "I wish the mobile world" which is mobile UCC(User Created Contents) ponpy/invitation service web site(www.6005plus.com) was constructed. In 6005plus.com web site, which users could easily produce mobile contents and establish mobile web service servers as well, in order for mobile service users to create mobile invitation or ponpy and use it. But the service 6005plus.com advocates is that users can attach ponpy and invitations to the MMS/SMS Call back URL, which needs resolution since it has several inactivated problems. In this paper, we allow users who registered 6005plus.com can create mobile card, invitation, and personal ponpy with registration, so that apply automatic generation technique for users to experience ponpy/invitation service into MMS/SMS Call back URL which 6005plus.com advocates through registration. We also designed my page to which users can send their contents easily, conveniently and by one-stop.

Although the amount of UCC(user created content) rapidly grows nowadays, there are various problems in authoring, distribution and management of this abundant content because the platforms for fabrication and replaying content are not compatible and the authoring environments are not sufficiently interoperable with other site or with each other. In this paper, we propose a CPMS(content publication and management system) scheme improved in interoperability to solve these problems, and we design a novel system enhancing the efficiency and speed of content distribution and management by minimizing the repetitions in the processes of production, reshaping, and publication. Moreover the proposed system adopts an improved content management technology by changing from simple point-to-point method to the centralized distribution method, and as for the service scheme, we change from the site link method to the database link method, and we also take duplex interlink scheme instead of simplex one. We finally compare the proposed system to the conventional ones as points of view of compatibility and interoperability to prove the improved performance of our system.
