Recent developments and integration of IT are expanding the possibility of various instructional learning methods in education environments. Contemporary learning theory such as open education, self-directed learning, student's centered learning describes the students as an active and engaged information user and underscores the importance of information literacy. Therefore, school library today focus on the process of learning-teaching process rather than dissemination information, and emphasized the focus of the school electronic library as information center. The purpose of this study is examined physical components of School Electronic Library, design a model of information system and suggests a strategy for implementing teaching-learning process support services based on school electronic library and information system.

As new smart devices are evolved into the intelligent agent who can reflect user intention and use context, user experience design for easy and convenient usability becomes a core competitive edge. Under the assumption that human centered natural interaction is necessary for the optimal smart TV experience, this study explores the types of voice interaction which are peculiar to TV watching context. In order to build a model for the users to naturally interact with Smart TV, conversation patterns were collected by requesting key features of Smart TV to intelligent agent. Collected sentences were applied to CfA model and classified by responses to activate features. The classified conversation patterns were divided into feature activation and information search. This study has identified that CfC1 occurred when voice interaction between Smart TV and users was vague and CfC2 occurred when the requests were complex or conditional. In conclusion, Simple Request Type is the most efficient model and voice interaction is more appropriate to use to clarify users' vague requests.

As user-centered design and content development emerge, the research and the establishment of items on usability evaluation are becoming more important. However, research on usability evaluation for digital systems in specific areas of mobile applications is still incomplete. Due to the recent development of wearable devices and smartphones, development and usage of quantified-self and life-logging applications has been rapidly increasing. This study aims to establish evaluation items and the main factors for the usability assessment of the applications that support life-logging services. In order to establish evaluation factors for life-logging application usability, we first gathered existing usability assessment items and selected the initial items through the Focus Group Interview(FGI). Second, we conducted user assessment surveys on the selected initial questionnaires and performed reliability and exploratory factor analyses based on the survey results. Third, through the statistical analyses results, we established 28 usability assessment items and four factors: recognition; functionality; aesthetics; and satisfaction. Finally, we discussed the expectations and limitations of the established usability assessment. The results from this paper could be used as a guideline for the usability assessment of life-logging applications and thus will contribute to effective content development.

Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

Among web-based systems being widely used now, there are so many systems which are still using an user-level access control method. By successfully applying role-based access control(RBAC) to web-based application systems, we can expect to have an effective means with reinforced security for Internet-based systems. In order to apply RBAC to web-based application systems, we should come up with a system architecture for it. I proposed a system architecture which is needed to apply RBAC to web-based application systems. The proposed system architecture is largely composed of system composition and system functioning. For details, firstly, a certificate used by RBAC is specified. Secondly, a system architecture using a user-pull method is proposed and overall system components are mentioned with a role server being centered. Then, I showed how the system architecture can work to carry out RBAC on web-based application systems. Lastly, the analyses on the proposed system architecture are described for the purpose of proving its feasibility.

A motion-based sports game uses a motion sensor or a camera to exercise based on body movements, and it is possible to obtain exercise effects such as improving physical strength while enjoying the game. In prior works, various studies such as usability evaluation has been conducted on motion-based sports games. However, there has been no discussion about how the exercise effect is exerted on users when experiencing motion-based sports games as individual or team play. This study compared the user's exercise effects by analyzing the user's ECG (Electrocardiogram) sensor and the Kinect sensor's skeletal information using Nintendo Switch game that is played individually and as a team. In this paper, the experimental design and method, the quantitative measurement results based on ECG and Kinect, and the results of the post-test subjective measurement are discussed.
