소셜 네트워크 서비스의 확산과 더불어 소셜 네트워크 게임(이하에서는 소셜게임이라 함)이 부각되고 있다. 한편, 소셜게임이 인기를 끌면서 소셜 네트워크 서비스가 더욱 확산되는 계기가 되기도 한다. 사용자들을 소셜게임에 몰입하도록 유인하는 요인이 무엇인가를 파악하면 소셜 네트워크 서비스가 더욱 발전할 수 있는 방안을 찾을 수 있다. 따라서 본 연구는 사용자들을 소셜게임에 몰입하도록 유인하는 요인이 무엇인가를 분석하는데 있다. 본 연구에서는 대표적인 소셜 네트워크 사이트라 할 수 있는 페이스북의 소셜게임 사용자들을 대상으로 설문조사를 실시하였다. 280명의 사용자들을 대상으로 한 설문을 통해, 소셜게임에의 몰입, 게임스토리, 게임그래픽, 게임사회화, 게임 통제력, 게임 사용용이성의 관계를 구조방정식모형으로 분석하였다. 특히, 게임 사회화와 게임그래픽은 몰입에 직접적으로 영향을 주기도 하며 게임 사용용이성을 통해 간접적으로도 영향을 주었다. 한편, 게임스토리는 몰입에 직접적으로만 영향을 주고, 게임 통제력을 게임사용 용이성을 통해 간접적으로 영향을 준다. 본 연구는 몰입이론과 기술수용이론을 토대로 하고 있지만, 소셜게임에서의 몰입에 대한 최초의 연구이기 때문에 후속 연구에 지침이 될 수 있다. 또한 소셜게임을 개발하는 사업자들이 무엇에 역점을 두고 게임을 개발하고 서비스해야 할 것인가에 대한 지침이 될 수 있다.

The purpose of this study is to explore determinants which affect the significant increase in the user acceptance of smart phone. This study also analyzes the effect of each variable on the actual acceptance by empirical methods. In this study, first, the system quality and the service quality are defined as independent variables based on developed IS success model of DeLone & McLean(2003). Second, we proposed the research model by providing trust and perceptual immersion as intermediate variables, and user satisfaction and actual use as dependent variables by the proceeding research for accepting information technology and new service. Third, the statistical analysis is conducted by surveying to 200 smart phone users for verifying a validity of research models and hypotheses. As a result, almost hypotheses are accepted in confidence interval except for the hypothesis between security and trust variable.

Currently, in China, mobile live broadcasts are more popular compared to online live broadcasts. Accordingly, this research focused on Wanghong, SNS's flagship live broadcasting app. In other words, Wanghong refers to an internet celebrity who acts online on social network services (SNS) influencing many other people. This study specifically focused on one social network service and conducted a study on live app users. The study first analyzed the quality factors of an SNS to users using China's live app. Secondly, the research investigated in finding out the impact of quality on the satisfaction of live app users and how this affects the live app user's satisfaction on their intention of continuous use. Studies have shown that information quality, system quality, and social quality among SNS quality have a positive influence on live app user satisfaction. However, the quality of service and the quality of emotion was rejected by the hypothesis. Throughout this study, we hope to create an app that allows users to share more satisfying mobile images, thereby establishing various episodes holding beautiful places of their life on a real-time basis. It is hoped that live broadcasting businesses will spread a significant impact around the world. Finally, in the future, research on the study of collective comparison between Korea and China on SNS is believed to be meaningful.

The purpose of this study is to analyze the user experience and suggest the necessary improvements, in the blockchain based social platform Steemit. First, I investigated what is the blockchain and the characteristic of social platforms based on blockchain system. The honeycomb model was used to investigate and analyze the Steemit user experience, and the quantitative and qualitative data were analyzed through questionnaires and in-depth interviews. As a result of the research, the voting function, which is core function of the service in use, has high usefulness. Improvements suggestion that the editing tools and the abuse of voting function should be improved. I hope that this study will be used as a basic research material to improve the user experience of blockchain based social platforms.

We studied the methods for boosting a user participating service using KOSEN(The Global Network or Korean Scientists and Engineers) OpenLab service. OpenLab is a laboratory database of all the fields of science and technology, and it is different from other services in that basically it makes users register their information volunteerly. User participation service is not easy, so we made several strategies like promotion, event, and connection to other services. In result, we could collect about 4,300 laboratory database. Because user participation is a key concept for the Web 2.0, this study would contribute to the operation of the related services, especially to the services for scientists and engineers.

The primary purpose of this study is to examine the effects of contents quality characteristics on user's satisfaction and continuous usage intention in UCC services. Based on relevant literature reviews, this study posits five contents quality characteristics, that is, accuracy, completeness, variety, playfulness, and timeliness as key determinants of user's satisfaction and continuous usage intention. And then we structured a research model and hypotheses about relationship between these variables. A total 315 usable survey responses of UCC service users have been employed in the analysis. The major findings from the data analyses are as follows. Firstly, four contents quality characteristics of completeness, variety, playfulness, and timeliness had a positive influence upon user's satisfaction. Secondly, four contents quality characteristics of accuracy, completeness, playfulness, and timeliness had a positive influence upon continuous usage intention. Lastly, user's satisfaction had very significantly related to continuous usage intention in UCC services. From this study, we expect to suggest practical and managerial implications to UCC service providers.

Entering aging society and increasing individual's interests on wellbeing lead to increasing demands of healthcare service and various healthcare related applications are providedon app market or Internet. These healthcare services could enhance user's health status if the users continuously use the service. In order to enhance effectiveness of a healthcare service, the service user should comply with recommendations or directions are provided by the service. However, previous studies of healthcare service are not considered effects of compliance intention on continuous usage. Hence, we tested how user's compliance intention effect on continuous usage intention of healthcare service based on theories of information system and medical information. Moreover, we found that compliance intention of users for healthcare service is an important factor on sustainability of healthcare service. Additionally, we investigated what factors are related with user's compliance intention.

Since users want to have services correctly in their own position and surrounding circumstance in ubiquitous computing environment, it is very important to search, compose basic services and provide suitable services according to various circumstances. However existing techniques have been studied on service discovery mainly and lack consideration for position or preference of users. Furthermore, on service composition, they lists basic services simply and do not propose concretely method of use service history data for service composition. Therefore we propose a framework for context-based service provisioning middleware system, called COSEP, and Ontology engine with data ming. This research discovers services by reacting dynamically to circumstance information such as time and position of user, composites services using Ontology engine with data ming and offers newly created optimal services to users.

With the increase of the number of Internet users, various methodologies have been proposed for the effective design of web page. However, the prior methodologies have focused only on the functional aspect of web page while ignoring the emotional aspects of web pages. This paper focuses on the emotional design of home pages and aims to provide a methodology to design a web page suitable for goal emotions. In order to achieve the main purpose, we have conducted three related studies. First, we have identified basic emotional dimensions representing various feeling users have from web pages as a pool of emotional adjectives. Second, we have identified key design elements related to the emotion by observing the design process of expert designers. Third, we examined the causal relation between the perceived emotion and designed elements. The results indicate that some design elements are more effective to produce certain feeling than others. This paper ends with limitations and implications of the study results.
