Currently, in China, mobile live broadcasts are more popular compared to online live broadcasts. Accordingly, this research focused on Wanghong, SNS's flagship live broadcasting app. In other words, Wanghong refers to an internet celebrity who acts online on social network services (SNS) influencing many other people. This study specifically focused on one social network service and conducted a study on live app users. The study first analyzed the quality factors of an SNS to users using China's live app. Secondly, the research investigated in finding out the impact of quality on the satisfaction of live app users and how this affects the live app user's satisfaction on their intention of continuous use. Studies have shown that information quality, system quality, and social quality among SNS quality have a positive influence on live app user satisfaction. However, the quality of service and the quality of emotion was rejected by the hypothesis. Throughout this study, we hope to create an app that allows users to share more satisfying mobile images, thereby establishing various episodes holding beautiful places of their life on a real-time basis. It is hoped that live broadcasting businesses will spread a significant impact around the world. Finally, in the future, research on the study of collective comparison between Korea and China on SNS is believed to be meaningful.

Mobile GUI design is changing from an existing design that emphasizes intuitive cognitive effects to an affordance design that naturally triggers users' behaviors. However, in the GUI design, the current affordance only uses some partial design elements and cannot achieve effective design, and the concept of affordance design still has confusion and uncertainty. For this reason, this paper redefines affordance by examining the concepts and types of it in the pre-research. In addition, through questioning the type of affordance, a questionnaire was designed for the GUI elements of social software. According to the results of the survey, the evaluation of the affordance of the GUI design elements was derived, and the GUI design of the social software was compared and analyzed. Then according to the deep interviews, a GUI design proposal that can effectively use affordance was proposed.

Recently. smartphones have been popularized rapidly and now located deep in our daily life, providing a variety of services from banking, SNS (Social Network Service), and entertainment to smart-work mobile office through apps. Such smartphone apps can be easily downloaded from what is known as app store which, however, bears many security issues as software developers can just as easily upload to it. Military apps will be exposed to a myriad of security threats if distributed through internet-basis commercial app store. In order to mitigate such security concerns, this paper suggests a security guidelines for establishing a military-excusive app store and security verification system which prevent the security hazards that can occur during the process of development and distribution of military-use mobile apps.

As the smartphone market grows, the needs for its new business model are also increased. However, most previous researches on smartphone applications focused on Technology Acceptance Model(TAM) and Rogers' Diffusion of Innovation Theory so that there was lack of researches on characteristics for actual smartphone users. In this research, we divided the smartphone applications into five category functions (Call & Text/Music & Video/Information Search/Game/Social Network Service (SNS)). We analyzed characteristic differences of users who used the each application category and found that the differences were statistically significant in both demographic and smartphone usage characteristics (frequency of downloading applications, and download experience of paid applications). Additionally, the smartphone usage characteristic is closely related to the usage duration. The representative result is that the characteristics of people used Music & Video function actively were women in their 20s who downloaded applications more than three times per week, and had a download experience of paid applications. It is positive result for players in the application markets, because it means the users are willing to pay for downloading the paid applications. However, large companies already occupied most of the market share in music applications so that small and medium-sized players should develop an innovative and distinguishable business model in order to success. We believe this research result would provide significant implications for the players in planning the successful business model and developing an user-specific application product.

In this paper, we examined the causes of information privacy concerns, trust and related factors in social network services. On the basis of the 'elaboration likelihood model,' we established factors such as information quality, privacy policy, perceived SNS app popularity and optimism bias affecting information privacy concern of SNS users. In addition, we analyzed the relationship between information privacy concern, trust in SNS members, trust in SNS platform and intention to use. Finally, on the basis of the 'trust transfer theory', we analyzed the relationship between trust in SNS members and trust in SNS platform. The results of the study showed that (1) information quality, privacy policy and optimism bias had the significant effects on information privacy concerns, (2) perceived SNS app popularity didn't affect information privacy concerns, (3) information privacy concerns had the significant effects on trust in SNS platforms (4) in accordance with the trust transfer theory, trust in SNS members had the significant effect on trust in SNS platforms, and (5) trust in SNS members had the significant effect on intention to use, while trust in SNS platform didn't have the significant effect on intention to use. The findings of the study are expected to help to improve the SNS firms' understanding towards customers' information privacy protection behaviors and trust.

최근 스마트 기기의 발전 및 보급 확대에 따라 사용자의 범위는 계속해서 증가하고 있다. 이에 따라 모바일 쇼핑 이용자들이 지속적으로 늘고 있고, 광고 또한 인터넷 기반에서 모바일 플랫폼 기반으로 변화하고 있는 추세이다. 모바일 기기의 중요성이 커지고 편의성이 증대되면서 소비자들의 구매방법에도 많은 변화가 일어나고 있는데, 정보를 탐색하고, 구매를 결정하고, 결제하는 행위 등 모바일에서 이루어지는 비중이 늘어나면서 앱을 구성하는 것 또한 중요한 마케팅 전략으로 자리잡고 있다. 본 연구의 목적 역시 사용량이 급증하게 된 모바일 쇼핑에서 SNS활용도의 조절효과를 중심으로 하여 광고 유형과 애플리케이션 특성이 소비자들의 구매의도에 미치는 영향에 대해서 살펴보고 결과를 제시하여 관련 업계에 도움을 주고자 한다. 본 연구에서는 모바일 쇼핑 이용자들의 모바일 쇼핑을 통한 구매의도에 미치는 영향 요인을 파악하기 위한 선행연구와 이론적 배경을 통해 모바일 광고유형, 앱 특성에 관한 고찰과 구매의도와의 인과관계를 살펴보았다. 연구의 목적은 모바일 쇼핑 이용자들의 모바일 쇼핑을 통한 구매의도에 미치는 영향 요인을 파악하고, 변수들 간의 관계를 규명하는데 있다. 구매의도에 영향을 미치는 요인을 광고 유형, 앱 특성으로 구분하고 이들 변수들이 구매의도에 미치는 영향력을 조절하는 변수로 SNS활용도를 도입하였다.
