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.

스마트기기 및 클라우드 서비스 확산, 소셜네트워크서비스(SNS) 성장 등에 따라 인터넷 경제는 재도약하고 있으며, 거대 플랫폼사업자를 중심으로 한 모바일 생태계 구축경쟁에 따라 모바일 앱, 소셜커머스 등 분야에서 중소벤처기업에게 새로운 기회가 열리고 있다. 아울러 인터넷을 통한 국경간 콘텐츠 공급 확대, 오픈마켓 활성화 등에 따라 글로벌콘텐츠 경쟁이 심화되고 있으며, 인터넷의 일상화에 따라 사회 정치 문화, 방송통신 산업에 대한 인터넷의 영향이 확대되고 있다. 스마트 생태계 구축경쟁과 인터넷 중심 융합으로 특정지워지는 새로운 방송통신 패러다임은 기존 방송통신산업구조와 규제체계의 전환을 촉구하고 있으며, 방송통신 융합을 촉진하고 방송통신산업을 육성하기 위해서는 C(콘텐츠) - P(플랫폼) - N(네트워크) - T(기기)를 아우르는 종합적인 접근이 요구되고 있다. 본 고에서는 우선 방송통신산업 동향과 정책환경 변화를 살펴본 후 네트워크 고도화, 전략적 R&D, 중소 벤처기업 육성, 콘텐츠산업 경쟁력 제고 등 방송통신산업이 한 단계 더 도약하기 위해 필요한 주요정책과제 들을 살펴본다.

Recently, market of mobile spatial information service is increasing along with enlargement of geo-spatial information utilization area and spread of smartphone. In particular, smartphone users look forward to utilizing spatial information service more easily and conveniently. Korea has the potential for spatial information technology development, but does not have enough governmental support to develop various spatial information service in mobile network environment. Hence, it is need to make governmental support plans for utilizing mobile services and promoting the related industry base on mobile spatial information. In this paper, we propose governmental action plans for utilizing mobile services and promoting the related industry by surveying mobile application/web services and analyzing demands of mobile spatial information experts.

Social Network Service has been extremely popular these days and providing diverse features and functions to users. Social networking and interest sharing in between users are key factors of SNS and this circles back to draw more users to the service. Web is the first media to provide SNS and mobile is the next. The service based on mobile environmental uniqueness such as Location-based-service(LBS) is the key success factors to convert users to web SNS to mobile SNS. TV has also been a possible SSN market to draw users to share interests and participation. However TV has been always community electronics in family members and personalization to provide SNS has been barrier to overcome. In this study, we explorer ideas of key factors of personalization in TV environment and conducted a field study to define characteristics of TV personalization in terms of depth, method, style and structure. Research finds out that there are significant differences in these categories.

As the recent advances in network and wireless communications and semiconductor design and process technologies, our computing platform is rapidly shifting from desktop PCs to mobile devices such as UMPC (Ultra Mobile PC), Tablet PC, and Smartphone. Especially, wide-spreading Smartphones allow a new field of application based on location based services available with an user interface called augmented reality (AR). Therefore, this paper introduces an implementation of AR using various OpenAPls on Android Smartphones. In order to utilize enrich user data in real time, the system integrates with location based social network services also with OpenAPI. These APIs enable third-party developers to make use of rich contents of many portal web sites. The prototype was implemented on the real Android phone, Sky Sirius, and the result shows that it can provide an efficient location based service using AR technology without any constraints on mobile devices; in addition, it connects SNS to AR for sharing user data including photos, videos, and messages based on a specific location.

On top of presenting the possibility of expanding the game space to social space through mobile communication, MSNG reinforces the strengths of SNS and the fun of games through closer networks between users. This study empirically verified the effects of the characteristics of MSNG on interactions and user satisfaction by dividing the main characteristics of MSNG into graphics, challenge spirit, and reward, and then dividing the main characteristics of mobile social network service into social interaction and technical interaction. In the results of study, the main characteristics of MSNG such as graphics, challenge spirit, and reward all had significant effects on the social interaction and technical interaction while the social interaction and technical interaction of MSNG also had significant effects on the user satisfaction, so that the hypotheses of this study were all selected. The influence of the characteristics of MSNG on interactions might be because of shared feedbacks through graphics, game tasks, and reward in the performance process of MSNG, and such interactions make diverse people have the horizontal or circular communication, which is led to the increase of user satisfaction.

Recently, social network sites are very popular with the enhancement of mobile device function and distribution. This gives rise to the registrations of the people on the social network sites and the usage of services on the social sites is also getting active. However, social network sites' venders do not provide services enough compared to the demand of users' to share contents from diverse roots by users effectively. In addition, the personal information can be revealed improperly in processes sharing policies and it is obvious that it raises a privacy invasion problem when users access the contents created from diverse devices according to the relationship by policies. However, the existing methods for the integration management of social network are weak to solve this problem. Thus, we propose a model to preserve user privacy, categorize contents efficiently, and give the access control permissions at the same time. In this paper, we encrypt policies and the trusted third party classifies the encrypted policies when the social network sites share the generated contents by users. In addition, the proposed model uses the RCBAC model to manage the contents generated by various devices and measures the similarity between relationships after encrypting when the user policies are shared. So, this paper can contribute to preserve user policies and contents from malicious attackers.

Social network service is service that enables the human network to be built up on web. It is important to record users' information simply and establish the network with people based on the information to provide with the social network service effectively. But it is very troublesome work for the user to input his or her own information on the mobile environment. In this paper we suggested a system which classifies users' behavior using context and creates blogging sentences automatically after inferring the destination. For this, users' behavior is classified and the destination is inferred with the sequence matching method using Naive Bayes classification. Then sentences which are suitable for situation is created by arranging the processed context using the structure of 5W1H. The system was evaluated satisfaction degree by comparing the created sentences based on actually collected data with users' intension and got accuracy rate of 88.73%.
