Intelligent applications are crucial for increasing the popularity of shared urban electric bicycles (EBs). Building an application platform architectural system that can satisfy independent user operations is critical for increasing the intelligent usage of shared EBs. Consequently, we collected online reviews of shared EB applications, conducted semantic processing and sentiment analysis, and refined the positive and negative review data for each function. The positive and negative review indices of each function were calculated using the formulae for positive and negative review indices of product functions, thereby determining the functions that need to be improved. Each function of the Shared EB application was improved according to its business process. The main contributions of this study are to build a user requirement architecture system for the Shared EB application with five dimensions and 22 functions using the Delphi method to design the user interface (UI) of this application based on user satisfaction evaluation results; to create a high-fidelity dynamic interaction prototype and compare user satisfaction before and after improving the Shared EB application functions. The testing results indicate that the changes in the UI significantly improve the user experience satisfaction of the urban Shared EB application, with the positive experience index increasing by 69.21% and the negative experience index decreasing by 75.85% overall. This information can be directly used by relevant companies to improve the functions of the Shared EB application.

User reviews posted in the application market show high relevance with the satisfaction of application users and its significance has been proven from numerous studies. User reviews are also crucial data as they are essential for improving applications after its release. However, as infinite amounts of user reviews are posted per day, application developers are unable to examine every user review and address them. Simply addressing the reviews in a chronological order will not be enough for an adequate user satisfaction given the limited resources of the developers. As such, the following research suggests a systematical method of analyzing user reviews with a cost-benefit analysis, in which the benefit of each user review is quantified based on the number of positive/negative words and the cost of each user review is quantified by using function point, a technique that measures software size.

This study investigates predictors of continuance intention and purchase intention in mobile application(App) stores. This study identifies the structural relationships among app store quality, user habit, switching costs, user loyalty, continuance intention, and purchase intention in mobile application stores. The results indicate that user loyalty increases continuance intention and purchase intention and that user habit positively affects perceived switching costs and user loyalty. App store quality is a formative construct including quality of content, ease of use, and security. App store quality affects user habit positively. This study theoretically and practically contributes to the integration of influential factors for continuance intention as well as purchase intention.

An application that has a simple user interface not only motivates a user to continue using the application, but also enables the user to develop their mental model for the application - the like of which is a product of their interaction with the application. In the information systems literature, little empirical research has been undertaken on the effects of the mental model and motivation on smartphone users' behavioral beliefs. Therefore, the aim of this study is to suggest a research model that can examine the following: 1) the effects that the mental model has not only on smartphone users' behavioral beliefs (that is, perceived usefulness and ease of use of an application) but also on their behavioral intention to use an application and 2) the effects that smartphone users' intrinsic motivation has on their behavioral beliefs through an expansion of the mental model. A survey is conducted, and structural equation modeling is then used to analyze the survey data. The results, through consideration of variables such as intrinsic motivation, perceived usefulness, perceived ease of use, and user satisfaction, indicate that the mental model has an indirect effect on a user's intention to use an application.

The purpose of this study was to examine the factors related to satisfaction of users for the order communication system (OCS). The subjects of this study were 98 clerks at Chosun university hospital. The instruments used for this study were the conveniency and the practical application of the data developed by Lee, the satisfaction level developed by Sea Seang-mi and Kim in-sook. The data was analyzed by using the t-test, ANOVA, Pearson Correlation, Stepwise Multiple Regression with SPSS 10.0 program. The mean scores of the conveniency, the practical application of the data and the satisfaction level of user for the OCS was 3.28, 3.29 and 3.34, respectively. In general characteristics of the respondents, influencing factors to the perceived the conveniency of user for the OCS were gender, career and department. In general characteristics of the respondents, influencing factors to the perceived the practical application of the data of user for the OCS were department. In general, characteristics of the respondents, influencing factors to the perceived the satisfaction level of user for the OCS were gender, career and department. The correlation between the satisfaction level and the practical application of the data were statistically significant. The main factors influencing to the satisfaction level of user for the OCS were the practical application of the data (90.3%). In conclusion, The main factors influencing to the satisfaction level of user for the OCS were the practical application of the data. Therefore, it is recommended that guidebooks of user for the OCS or various OCS programs to promote the satisfaction level of user for the OCS and to improve the satisfaction level of user for the OCS should be developed.

The increase in the number of smartphone users has recently been steep, which started to offer companies and individuals more opportunities to enter into a new business field. Furthermore, the smartphone applications have become one of the hottest topics inside and outside the mobile industry. Still the market is in its infancy and intention to pay of charged application of most smartphone users is relatively low. However, rate of charged application in appstore is expected to be increase steadily for some years to come. In this perspective, it is important to consider the smartphone mobile application. Research on smartphone application is still in its early stage. Thus, the purpose of this study is to find what are the effective factors on user satisfaction and intention to pay of mobile application. Based on information system success model, we proposed system quality(stability, usability, security), information quality(timeliness, accuracy, enjoyment) and service quality(reactivity, reliability, empathy) as factors to effect on user satisfaction in mobile application. The results showed that stability, usability, timeliness, accuracy, enjoyment, reactivity and empathy affected significantly user satisfaction. The relationship among satisfaction and intention to pay of mobile application was significantly supported. The implications of the findings is that firms and individual developers of mobile application should focus on customer retention through enhancing satisfaction and quality.

Ubiquitous Computing은 소프트웨어 Architecture를 구현하는데 있어서 많은 도전들을 필요로 한다. 그 중에 하나는 User가 한 컴퓨터에서 다른 컴퓨터로 이동할 경우의 User Mobility를 고려한 것으로 User뿐 아니라 Application도 같이 이동하여 예전의 컴퓨팅 환경을 그대로 복원하게 되며 User가 작업하던 뜯을 계속해서 할 수 있게 만드는 것이다. 본 논문은 이러한 Ubiquitous Computing 환경을 만들기 위해 MuSa Architecture를 제안하고, Application 이동에 필요한 Manager들을 설명하도록 한다.
