This study is about comparing the mobile user experience of Facebook and Instagram which are most often used among the recent SNSs by the people in their 30s and under. This study analyzed the user experience level after dividing the user experience factors through the Creating Pleasurable Interfaces model, and suggested the mean analysis as well as the result of Wilcoxon rank test which is a nonparametric statistics method. As a result of study, the Display information visually factor in functional factor and the configuration of the main page in convenient factor were a statistically significant difference in the mobile user experience of Facebook and Instagram. It is expected that this study may help seeking the user experience factors to be promoted preferentially in a competitive situation through the statistical comparative evaluation of the experience of two SNS users.

This study aims to discuss the current status of the ride-sharing platform industry, which embodies the core values of the 4th Industrial Revolution, sharing and connectivity, as well as economic, industrial, and legal issues. To understand the position of competing groups, the research conducted extensive literature reviews on domestic and international cases of technical and legal issues of the sharing economy. The result indicates that the ride sharing industry showed the economy of synthesis in which production, supply, distribution, and consumption are on one platform. It made possible to share values to users and synthesize them with new services through easy-access mobile application technology. To resolve the conflicts between the taxi industry and the ride sharing industry, this study suggests the following: Ride-sharing companies should make contributions to provide legitimate services. The taxi industry needs to understand the value of the new industry and consumers who chose the shared platform service. The significance of the current study is that it proposed a comprehensive analysis and policy direction toward the issue of balance between public and private interests and legal stability.

This study attempted to present a strategic direction that helps in vitalizing the domestic fashion and beauty magazine industry by examining the factors that influence the intention to use the fashion beauty magazine curation service. A survey was conducted on 314 college students in Korea, and the results were derived through a series of analysis processes using the SPSS 21.0 and AMOS 21.0 programs. Technology self-efficacy had a positive effect on perceived ease of use and perceived usefulness, perceived value had a positive effect on perceived usefulness. Technology self-efficacy and perceived value had a positive effect on intention to use, perceived ease of use had a positive effect on perceived usefulness. Perceived ease of use did not have a significant effect on intention to use, but perceived usefulness had a positive effect on intention to use. In order to increase the intention of using the mobile-based fashion beauty magazine curation service for college students, it is necessary to clearly understand the value and usefulness of the curation service.

The software market has diversified service needs due to the expansion of the mobile market. To this end, the company intends to produce various apps by extending to the design domain based on the structured architectural assets of the domain market. In this study, we propose an evaluation model that can evaluate the efficiency for servicing assets that reflect the domain characteristics of architecture based on cloud. Based on the characteristics of ISO/IEC 25010 quality model of SQuaRE Series, a software evaluation standard, evaluation model sub-features for evaluating the efficiency of cloud-based asset data were constructed. When the architectural assets were designed as composite assets, they were designed to provide the flexibility of the evaluation model by applying the mandatory and optional evaluation elements of the sub-features that weighted the evaluation items according to the characteristics of the design domain.

This work is intended to investigate how the factors of enterprise mobile SNS affect user satisfaction and continuous use intention through technology acceptance model proposed by Davis. To achieve the purpose, this researcher explored Information Systems Success model proposed by DeLone & McLean, Technology Acceptance Model proposed by Davis, and Model after Acceptance, and on the basis of the investigation, performed a study. For the data of this work, 9 enterprises, each of which has more than 100 employees and is located in Seoul, were chosen, and a questionnaire survey was conducted on their 276 employees who experienced enterprise mobile SNS. As a data collection tool, a structured self-administered questionnaire was used. For data analysis, SPSS 18.0 and AMOS 18.0 were used for applying Structural Equation modelling. According to the results of this work, three factors of enterprise mobile SNS-systematic factor (system quality, information quality, and service quality), user factor (personal innovation and personal familiarity), social factor (social effects and social interaction)-affected user satisfaction and continuous use intention through perceived availability, perceived easiness, and perceived enjoyment. Also, it was found that the direction of effects matched a theoretical prediction. And, it was revealed that the decision variables and mediating variables significantly affected user satisfaction and continuous use intention. Theoretical and practical meanings were discussed for the study result, and some suggestions were made for the issues of this work and future studies.

Recently, public service for the improvement of quality of life and life support such as safety, aging, disaster, welfare, housing, economy, urban environment, traffic etc are actively developed based on open public data, and the spread of the network and the necessity of everyday life, smartphones are playing a role in providing public services. Currently, the development of science is changing the life expectancy of human beings and changing into social structure in which aged people become bigger due to various social conditions and low fertility and aging problems. However, the elderly who do not have easy access to information are very uncomfortable in dealing with mobile devices with very low accessibility and utilization of public services provided by mobile phones. Therefore, this study recategorizes the condition of the elderly presented in the previous study and identifies the problem through case analysis provided for the elderly. Also, we summarize the hierarchy of the core items of the existing interface design and derive it as an improvement index of the public service design for the improvement of the information accessibility of the elderly, and propose a design method to improve the utilization of the public service provided through the mobile device.

The study evaluates user experiences of I-um and Noondate, typical Social Dating Mobile Application Service in Korea, to suggest guidelines that are more user-centered and useful. I did some literature research followed with evaluation of theoretical backgrounds, present conditions. Also, I recasted to the six principles of "Honey comb model" by Peter Morville to conduct an in-depth interview. The result indicate that I-um needs to improve accuracy of matching system by checking user's interest and detailed profile. Noondate needs to develop the cards sorting systems so that user can supervise themselves. I expect this study will become a good resource for upgrading user experiences of Social Dating Service. I also believe that this study can guide other studies about user experience in other fields.

In this study, we propose a development environment for authoring quiz contents, which is based on the concept of "Gamification", which is the principle of Engagement and Reward. Future Services As a platform for authoring and composing technology, and also for educational contents authoring, I have reviewed key features and implications of HTML5 (CSS3.0, Java Script, etc.) along with key technologies. These features are key technologies for building a true smart learning environment. Based on this, a case of applying the gamification technique to enhance the educational effect was proposed through the quiz contents model.
