최근 데이터의 범람과 더불어 빅데이터 시대가 도래 하면서 SNS 라는 새로운 플랫폼을 마케팅에 활용하고자 하는 기업들이 늘어나고 있다. 기업들은 이러한 SNS 상의 데이터를 분석하고 이를 공개 API 를 통해 마케팅에서 활용할 수 있다. 하지만 SNS 업체들은 과도한 트래픽 유발 및 보안상의 이유로 공개 API 의 사용을 제한하고 있다. 따라서 제한된 사용 횟수 안에서 효과적으로 공개 API 를 사용할 수 있는 고객맞춤 최적화가 필요하다. 기존의 멀티캐스팅을 이용하면 이러한 고객맞춤 최적화가 가능하지만 SNS 의 특성을 반영한 것이 아니기 때문에 SNS 마케팅에서 활용하는데에는 한계가 있을 수 밖에 없다. 본 논문에서는 이러한 멀티캐스팅을 이용한 고객맞춤 최적화의 한계를 보완하고 SNS 의 특성을 보다 잘 활용할 수 있는 새로운 SNS 마케팅을 위한 고객맞춤 최적화를 제시한다.

With the development of SNS, many different areas including education are utilizing SNS in various ways. And there are more and more learners and teachers who intend to use it for learning. Lately, however, the students using SNS environment hardly consider the issues regarding copyright, so this is raising even legal issues, too. Therefore, this study has examined the degree of recognition of undergraduates on copyright and extracted the general cases of copyright which undergraduates may face in the actual class or everyday life. The cases extracted are expressed in the rules of "If ~ Then", stored in the knowledge base of rules in the rule-based system, and realized as the mobile web. And regarding the copyright-related problems inputted by the students, similar rules are drawn from the knowledge base of rules so that they can solve copyright-related problems anytime, anywhere with the mobile web in a self-directed way.

This work is intended to investigate how the factors of enterprise mobile SNS affect user satisfaction and continuous use intention through technology acceptance model proposed by Davis. To achieve the purpose, this researcher explored Information Systems Success model proposed by DeLone & McLean, Technology Acceptance Model proposed by Davis, and Model after Acceptance, and on the basis of the investigation, performed a study. For the data of this work, 9 enterprises, each of which has more than 100 employees and is located in Seoul, were chosen, and a questionnaire survey was conducted on their 276 employees who experienced enterprise mobile SNS. As a data collection tool, a structured self-administered questionnaire was used. For data analysis, SPSS 18.0 and AMOS 18.0 were used for applying Structural Equation modelling. According to the results of this work, three factors of enterprise mobile SNS-systematic factor (system quality, information quality, and service quality), user factor (personal innovation and personal familiarity), social factor (social effects and social interaction)-affected user satisfaction and continuous use intention through perceived availability, perceived easiness, and perceived enjoyment. Also, it was found that the direction of effects matched a theoretical prediction. And, it was revealed that the decision variables and mediating variables significantly affected user satisfaction and continuous use intention. Theoretical and practical meanings were discussed for the study result, and some suggestions were made for the issues of this work and future studies.

This study focuses on examining the determinants of smartphone-based social network services(SNS) use. That is, the study explores the key factors affecting the use of smartphone-based SNS. People who have been using online-based SNS such as Cyworld and Facebook for years are now using mobile-based SNS such as KakaoStory. Under the situation. the study attempts to draw key determinants of smartphone-based SNS use from the studies of TAM, hedonic information systems, and social perspectives. To test the hypotheses, we conducted partial least squares (PLS) analysis using a total of 233 data collected on the users of smartphone-based SNS including KakaoTalk and KakaoStory. The key findings are as follows : first, it is verified that both ease of use and usefulness, two main factors in TAM, had positive effects on smartphone-based SNS use. Second, for enjoyment and escapism considered as the two main factors of hedonic IS characteristics, only the effect of enjoyment on SNS use was significant. Finally, social ties as a factor of social characteristics had the most significant effect on smartphone-based SNS use. The result implies that smartphone-based SNS can be one of the major means of maintaining existing social ties.

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.

After platform changed from PC-based internet to mobile, SNS became new interactive media which relaces face-to-face interaction. the SNS users have already begun to recognize SNS as daily necessity. SNS market has been subdivided. In other words, SNS has entered into a period of vertical SNS that focus on contents and specific target. Therefore, It is necessary to analyze users for SNS planners. For this reason, analyzing why office workers who have the most powerful purchasing power use SNS is meaningful for SNS planners. Therefore, in this study, we analyzed the reasons for using SNS of office workers by studying relationship among office workers' stress, social support, self-expression and the use of SNS. As a result, the use of SNS has a significantly positive correlation with social support and self-expression. The self-expression in the SNS is not associated with stress, but rather it is the characteristics of the office workers. However the social support in the SNS affects to stress.
