Government and public institutions have been releasing a number of mobile applications in order to provide diverse public services in the mobile environment. However, due to their one-sided and fragmented service with the lack of adequate care for users, the utilization rate is extremely poor. Therefore, this study, based on a relevant literature review, identified and derived the five key factors (usefulness, convenience, interactivity, information credibility, and social pressure) for users' mobile service adoption. Then, through in-depth interviews with five users and five experts regarding the 'business support app' of one public agency (H institution) that specializes in SMEs, we found that all of these factors are important for users' mobile service adoption. Users' satisfaction could be significantly improved through real-time response to their needs. In addition, providing them with useful and tailored information can lead to mutual trust between public institutions and users. Consequently, as these user-oriented services can increase users' loyalty and boost the utilization rate of the public apps, public institutions should always put persistent efforts to cope with users' demands.

The aim of this study is to investigate whether library public forums, which are conducted as a part of the library's information services, affect users' perception of libraries. We analyzed the variations in users' perception of libraries based on their participation in public forums held by the public libraries. Data was collected through a survey of users from the Seongbuk Public Libraries in Seoul, which hold public forums. It was discovered that users' perception of public libraries varied depending on whether they had attended the library's public forums or not. The study revealed that users who participated in library public forums had a better understanding of the public libraries compared to those who did not. Specifically, users who participated in public forums exhibited a deeper comprehension of the library's roles, higher trust in the library, and a greater willingness to visit the library. In addition, we found that users acknowledged the importance of public forums in libraries and expressed a high level of interest and willingness to participate in them. Based on these findings, we discussed the implications of library public forums on users' perception of libraries and highlighted the need for information services that are based on public forums.

In the previous surveys conducted on the users of digital multimedia centers at major public libraries, their facilities, contents, staffs and operating system have been found to be the most significant factors for determining the user's satisfaction. The purpose of this study is to seek practical ways of improving digital information services at public libraries by surveying Hanbat Library Users' satisfaction on these four factors. The statistical analysis of the surveyed data has shown that the general satisfaction with the digital service was relatively good: 4.68 out of the maximum scale of 7, that their satisfaction with the facilities were increased but those with staffs and operating system were decreased, and that 69.7% of the users were not willing to learn how to use contents mainly because they do not trust the staffs' ability to teach. Therefore, it was confirmed that the continuous reeducation of staffs and the expansive recruiting of professionals are essential for improving digital information services.

In this article, the protection system on wireless mobile communication circumstance for the information providers and the users is recommended. Because of its usefulness and convenience, the users of the wireless mobile communication are growing explosively. However, the function of protecting data systems is not secured enough so, personal information may disclose to the outside, regardless of one's intention. Therefore, the contents protection system, which can provide information to the user or hide it depending on user's identity, is suggested. If so, the providers and the users can trust each other for interchanging information, also the users may safely use contents menu whatever they want by doing simple certification process.

In related to mobile communication environment, many researchers have studied problems concerning current locations of mobile users and exposure of their movements in the privacy aspect so far [1,2,3,4,5,6,7,8,9]. Among them, Kesdogan and Pfitzmann [3,6] proposed effective solutions using temporary pseudonym identification, called TP(Temporary Pseudonym ) to solve them. After that, Kesdogan et al. proposed an improved method protecting mobile users from some types of attacks of network providers in [8]. However, among their methods, in particular the method, attaching the other new device (so-called Reachability Manager) to system against active attack of network providers, is alterative rather than practical and is not clear. Moreover, it requires the other cost and overhead. Therefore we propose a practical method against active attack of network providers without attaching new device in original environments. The basie idea of proposed method is to protect a fraud act of network provider as a inside user by exchanging a secret information, which only users and network providers know, via network provider between mobile user and the trusted third party (so-called Trust Device). Moreover, we introduce a new payment protocol which applied our method.

The problem of choosing the right product that will best fit a consumer's taste and preferences extends to the field of electronic commerce. However, e-commerce has been able to create a technological proxy for the social filtering process, known as online recommender systems (RSs). RSs aid users in filtering products and decisions on matters relating to personal taste. RSs have the potential to support and improve the quality of the decisions consumers make when searching for and selecting products and services online. However, most previous research on RSs has focused on the accuracy of the algorithms, with little emphasis on user interface and perspectives. This study identified transparency and feedback as possible ways to effectively evaluate RSs from the user's perspective. Thus, this research focused on examining and identifying the roles of transparency and feedback in recommender systems and how they affect users' attitudes toward the system. Results of the study showed that both transparency and feedback positively and significantly affected perceived trust, perceived value of the process, and perceived enjoyment. Furthermore, we found that perceived trust, perceived value of the process, and perceived enjoyment positively and directly affected users' intentions to use/reuse a recommender system.

At present, an intelligent transport system (ITS) is being actively introduced as an alternative plan to solve various transport problems, and a traffic information provision service, a field of ITS, is being provided to users through diverse media. However, the evaluation of how useful the traffic information provided to the road users is limited to a simple questionnaire, and the systematic evaluation about what factors affect the usefulness of traffic information has not been realized. Therefore, it is impossible to calculate user convenience occurring due to traffic information, This paper aimed to develop an index to evaluate user satisfaction levels with traffic information and develop a user satisfaction level model. A result of establishing a user satisfaction level model by executing a questionnaire survey for the analysis object of variable message sign (VMS), a representative information provision medium, showed that 'desire satisfaction', 'trust', 'understanding', and 'efficiency' have an effect. Of them, the 'understanding' showed the highest level, so it was seen that, in case of VMS, how easily the character, figure, expression, etc. provided in the information was understood by users has the biggest effect on the satisfaction level of the information. The next levels of effects on the satisfaction was in the order of 'user trust', 'efficiency', and 'desire satisfaction'.

It is no longer special for the gaming industry to provide a community to promote their games. Much prior research related to the community also focuses on the spread of community influence and its importance. In particular, the user community in the gaming industry is having a big impact on the company's revenue creation beyond the simple level of information provision and promotion of friendship. Therefore, providing a community at the same time as the game is released is becoming a common trend in the gaming industry This study attempted to explore factors influencing the design of more effective communities under the assumption that the user community will influence the loyalty of mobile games. The design elements of the community suggested in this study are the provision of interaction tools between users, the provision of information, and communication between the game maker and the users. This study aims to confirm that these design factors affect customer loyalty by reinforcing user empathy and trust in the game within the user community. After collecting data from 251 users active in the mobile game user community, the model presented in this study was empirically analyzed. As a result, the design elements of the game community suggested in this study were found to affect customer loyalty by strengthening the empathy for the game and the trust in the game developer.
