As smartphone use has been steadily growing over the past year, social networking on the mobile phones appears to be increasing. In this paper, we propose a cross-platform mobile architecture for supporting social applications. The key design objectives for developing the proposed system include: 1) providing personalized data through filtering information which is supplied by various social applications, 2) providing a cross-platform architecture for adapting various smartphones such as Apple iPhone and Google android. We verified system design by implementing a smartphone application which displays the filtered pictures from social network services such as Flickr and Picasa.

Social enterprises have a high cost structure, inefficient operation, and poor human and material resources due to a dual structure that must achieve both economic and social purposes. To solve this problem, collaboration, such as sharing resources and information between social enterprises, is emerging as an important management issue. Accordingly, in recent years, the establishment and operation of an online platform is being emphasized as a means to effectively support the problem of lack of resources (human resources, equipment, funds, and technology) between social enterprises, the promotion of joint projects between companies, and the establishment of organic information sharing and communication channels between companies. This study empirically analyzed how the required characteristics of the online platform that supports the collaboration of social enterprises vary depending on the characteristics of the enterprise (general characteristics, collaboration characteristics), and found that there are statistically significant differences depending on the size. These results are expected to be useful in deriving management plans for online platforms for cooperation support for domestic social enterprises in the future, and seeking ways to increase collaboration using the platforms.

Recently not only industry but also academy have shown an intense interest in social networking service. However, reckless imitation will not guarantee the successful eco-system of social networking service without rich understanding of growth driver and business model. Hence, this study aims at analyzing open platform strategy and business model conducted by a representative social networking service provider in order to provide platform operator, network operator, and portal provider with meaningful implications. Advertisers may pay great attention to social networking service because it has strong ability to provide users with spontaneous motivation to manage and update their profile, and these valuable information can be utilized for providing personalized advertisement on social networking service. As a result, one side of consumers in two side market, advertisers, tend to pay more expenditure to place advertisements. In addition, the open platform adopted by social networking service providers causes pro-sumers to participate in the eco-system, and thereby the explosive quantitative growth is realized. The fact of that this open social networking service can invade other web service area via an unified platform indicates that it may expand its service scope into a wide variety of web service areas. Hence, domestic portal services providers and network providers should consider social networking service not as one of new web services but as an disruptive service platform. Corresponding to the emergence of social networking service, especially if their business area is related to display advertising market, they should seek a way to provide social networking service access users's newly updated information and develop innovative media technologies to enter context awareness ads market.

This paper analyzes the economic effects when platform provider including CP contributes to broadband universal service and uses broadband bandwidth providing high quality network service. In this model, the contribution rate of broadband universal service is determined by ISP and platform provider sets its price of contents. The main results are as follows. First, the traffic usages is less than social optimum when the market of contents is monopoly. The sum of contribution fee and network usage rate must be less than marginal cost of network operation to get social optimum traffic. Second, the rate set by ISP is equal to social optimum when the market of contents is competitive. Third, when platform provider does not charge contents provided, ISP sets social optimum prices and the network usage rate for contents user is decreasing as advertisement revenue becomes larger. These results suggest that the platform provider should contribute to universal service funding to encourage the network investment of ISP.

This study examined the effects of a social tourism information platform on platform users' experiential value and e-loyalty and performed an empirical analysis with the aim to propose methods and implications regarding what strategies can enable practical application for sustainable growth in the operation of a social tourism information platform in the future tourism industry. The results of the analysis are as follows. First, the analysis supported the hypothesis that sub-factors of a social tourism information platform, such as interactivity, information reliability, and usefulness, have statistically significant positive effects on experiential value. Second, the analysis did not support the hypothesis that the sub-factors of a social tourism information platform, such as interactivity, information reliability, and usefulness, have statistically significant positive effects on e-loyalty. Third, the analysis supported the hypothesis that experiential value has a statistically significant positive effect on e-loyalty. Consequently, tourism companies should improve customers' experiential value by supplementing their existing platforms, considering the interactivity, information reliability, and usefulness of users based on these characteristics of social tourism information platforms. To increase e-loyalty to their social tourism information platforms, tourism companies should clearly and rapidly provide the information needed by users in addition to improving the visual design of such platforms. Moreover, to increase e-loyalty, the companies can incorporate their own killer content into platforms for users to have an enjoyable time, using platforms that stimulate their interest and give pleasure and fun, and this way, they can satisfy the users' needs for experiential value.

The wide spread of smartphones and the growth of the number of internet users are reshaping the SNS (Social Network Service). Merging into other service areas and creating new business models with high profits, SNS is no more a service simply providing personal connections. Now SNS has positioned itself as a service platform. SNG (Social Network Game) is a new outcome utilizing SNS as a game platform and showing a rapid growth rate in a short period of time. The number of SNG users is expected to increase steadily. In this study, we examine whether SNG user motivations lead to flow experience and future intention to use. For that purpose, we conducted a survey with smartphone users. The results indicate that flow experience functions as a mediator and user motivations indirectly affect intention to use through flow experience. This paper concludes with discussions on findings and suggestions for future research.

This study aims to investigate how consumers perceive the attributes (ubiquity, continuity) of metaverse fashion brands in a virtual space. It also empirically verifies the impact on consumers' perceived values (hedonic value, social value) and consumer behavioral intentions (intention to use the platform, intention to purchase virtual products). The results verified in this study are as follows: First, we confirmed that the metaverse attributes perceived by consumers in the virtual space of the fashion brand, ubiquity and daily extension, positively affect customers' perceived hedonic and social values. Second, we found that consumers' perceived hedonic and social values have a significant positive effect on their intention to use the platform. Finally, we found that consumers' intention to use the platform had a significant positive effect on their intention to purchase virtual products. The results of this study will have academic significance by expanding the scope of research related to identifying metaverse attributes and values by identifying metaverse attributes and consumer values that perceived by consumers in fashion brands' virtual spaces in the metaverse. This study suggests a direction and strategy for fashion brands to move forward in building virtual spaces on the metaverse platform. In this way, they can create perceived value for consumers that elicits positive consumer behavioral intentions.
