Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

With the rapid development of Social Network Service and with the diversification of user needs, new types of image-based SNS have emerged. Image-based SNS provides customized service to meet users' specified contents needs that have yet to be satisfied in conventional relation-based SNS like Facebook, leading the trend of service diversification. Unlike text-based SNS that has inconvenient view on a small mobile screen, image-based SNS provides the communication way focused on simple text message and image, and thus the main users of the image-based SNS are young people in their 20s who get accustomed to images, rather than text messages. Accordingly, the functions and roles of SNS UI have varied, and usability has been more important. With the users in their 20s who use image-based SNS, this study tried to look into the usability of the image-based SNS. To do that, heuristic evaluation method was applied to find UI problems. The main factors constituting usability were extracted, and user evaluation method was redesigned. Aside from the satisfaction measurement, this study conducted and analyzed a questionnaire survey with users in their 20s who used actual image-based SNS. This study analyzed usability factors that influenced of image-based SNS users. The analysis results are considered to be used as a fundamental material to improve usability in the process of developing social media service.

In order to achieve this research purpose, usability comparison factors were extracted through previous studies on the usability evaluation of artificial intelligence chatbot services, and based on case studies, artificial intelligence chatbot services applied to libraries were classified into their own website-based and SNS-based chatbot services according to the platform. Experiments, questionnaires, and interviews were conducted to evaluate the usability of website-based and SNS-based chatbot services applied to the library.

In order to increase the number of users in the global service brand, such as Instagram, facing the limit situation of new users, 40 ~ 50 new entrants are needed. However, 40 ~ 50s in Korea are not easily able to use these services because they have difficulties in these services. In this study, usability test is performed in terms of UX / UI about what is difficult for users in 40 ~ 50s to use in instagram, and what is the barriers to entry compared to domestic service The results are as follows. First, when localizing a global service, it is easy to understand, not a simple translation, and proper labeling should be considered. Second, major and frequently used functions should be considered to be intuitive to simplify the depth. Third, the design should be improved to increase the recognition rate of icons in terms of GUI.

The identified research result can be outlined more specifically as follows: first, informativeness of SNS was giving positive impact to some degree on the user satisfaction; second, connectivity of SNS was giving very positive impact on the user satisfaction; third, accessibility was giving very positive impact on the user satisfaction; forth, usability of SNS was giving very positive impact on the user satisfaction; fifth, amusement of SNS was giving very positive impact on the user satisfaction; the satisfaction level of SNS users gave positive impact on the further intention of SNS users. It was identified, however, that interactiveness of SNS was the factor that did not give much impact on the user satisfaction. This result comes from the analysis that SNS is convenient to actively explore and get further information that users wish to find, while they are insufficient in function to provide the information other users require or exchange information among users through the SNS.

The purpose of this study is to search information attributes suitable for SNS and to identify the influence of individuals or groups who contribute to the creation and diffusion of information in the SNS. The researchers extracted the accuracy, two-sided information, novelty, diversity, and experiential factors that influence the acceptance and diffusion of information in the SNS, and identified the relationships among the variables, the usefulness of information and the degree of information diffusion intention. And researchers studied market maven who play the key role in creating and diffusing SNS information. A total of 600 questionnaires were collected and 549 questionnaires were used to test the research hypothesis. The results of the study are as follows. Consumers considered information, which had accuracy, two-sided, and experiential attributes, as useful. But novelty or diversity information were regarded as unuseful because of motive to avoid ambiguity. In the Market Maven Group who have the ability to acquire and edit SNS information, however, there were weak or negative causality between experience and accuracy and information usability factors. but positive causality between novelty and diversity factors of information and usability.
