Purpose This study investigates that the routes of psychological ownership in Fanpage and the effect of psycholoigical ownership on customer loyalty based on psychological ownership theory. Fans are customers who clicked 'Like' on the fan page. These fans have a lot of friends on Facebook, so the word-of-mouth is more effective than other online communities. Therefore, it is necessary for fans to have psychological ownership, actively responding to the fan pages, and recommending them to friends. However, previous social network service studies have overlooked the importance of psychological ownership. In this study, we examine what factors can increase psychological ownership and show that customer loyalty can be enhanced through psychological ownership. Design/methodology/approach This study was designed to investigate the structural relationship between Fanpage Familiarity, Interaction(Customer-Brand interaction and Customer-customer interaction), Psychological Ownerhisp, and Customer Loyalty. Structural equation modeling with SmartPLS2.0 was used to analyze the relationships in the research model. Findings The results showed that Fanpage Familiarity and Customer-customer interaction is positively related with Psychological Ownership. However, Customer-Brand interaction did not influence Psychological Ownership. Psychological Ownership has a positive impact on Intention to Continue Using Fanpage and Recommend.

Typically, a smart car is equipped with access to the Internet and a wireless local area network. Moreover, a smart car is equipped with a global positioning system (GPS) based navigation system that presents a map to a user for recommending the shortest path to a desired destination. This paper presents the design and implementation of a real-time shortest path search system for directed and dynamic roads. Herein, we attempt to simulate real-world road environments, while considering changes in the ratio of directed roads and in road conditions, such as traffic accidents and congestions. Further, we analyze the effect of the ratio of directed roads and road conditions on the communication cost between the server and vehicles and the arrival times of vehicles. In this study, we compare and analyze distance-based shortest path algorithms and driving time-based shortest path algorithms while varying the number of vehicles to search for the shortest path, road conditions, and ratio of directed roads.

The environment-friendly agricultural product market receives consumers' great interests despite relatively few studies focused on consumers' decision making process of the environment-friendly agricultural products. This paper examines what factors influence on consumers' attitude and buying behavior on the environment-friendly agricultural product. In order to find the relative importance of each factor's influence, this study adopts multiple regression method based on the survey results of 500 people with the systematic random sampling. The results showed that consumers' favorable attitude towards the environment-friendly agricultural product were influenced by taste, freshness, food safety, and positive attitudes toward the environment-friendly agricultural product promotion. In addition, consumers' purchase intention was influenced by taste, food safety, environmental concern, and the promotion. Respondents recommend the environment-friendly agricultural product when they believe that the environment-friendly agricultural product had the values of taste, environmental concern, and promotion. Women are more active in buying and recommending the environment-friendly agricultural product; however, the price was not the statistically meaning factor. This study provides empirical data that was used for marketing and increasing the sales of the environment-friendly agricultural product. Future research was advised to examine more thoroughly on the relationships between the promotion efforts and purchase intention and the occasions when the price becomes the issue in the buying decision of the environment-friendly agricultural product.
