Ubiquitous computing which is providing various convenient services to user will prevail in future. To realize ubiquitous service, analyzing technical and information factors for service implementation is necessary. This paper defines ubiquitous service model to satisfy user demands and we analyze technical and information factors in order to realize services. Based on the factors, we extracts and classifies common compositions of ubiquitous services to suggest guidelines of service design.

The increased competition in service development in various industrial sectors highlights the importance of producing high-quality services that provide a positive user experience. Although usability evaluation is recognized as an important method of verification of high quality service and utility, the general usability evaluation method has limitations of not taking the characteristics of various participants due to its uniform composition to account. As the following flaws can reduce evaluation efficiency, developing a new guideline seems to be the next step. Thus, this study focused on criteria on how to evaluate the usability for children and proposed non-face-to-face remote usability evaluation configurations and progress guidelines to increase the effectiveness. The following usability evaluation experiment was conducted based on the proposed guidelines and in this process, the effectiveness of the guidelines was verified and the items that needed to be supplemented were derived. It is expected that the non-face-to-face remote usability evaluation guidelines proposed through the study will be used as the basis for designing usability evaluations of services developed for children.

The study aims to derive major factors from the results of needs analysis to develop the reference service model and guidelines at the national level. The literature review and case study enabled investigation of the considerations to develop the reference service model and guidelines. The Needs Analysis revealed librarians' and users' needs about the reference service. The major factors and implications derived from the analysis suggest the directions of the National-level reference service model and guidelines development process. This study has significance because it presented the implications and the development process of the reference service model and guidelines for domestic libraries, and directly contributed to the development of the reference service model and guidelines for the National Library of Korea.

The Knowledge Creation in early stages of new service development plays a critical role in the success of the service. The user is a crucial resource in creating knowledge in early stages of development, and user involvement is necessary. There are three roles the user can take part as in service development: informative, consultative, or participative. Based on these different roles, the process of knowledge creation varies. With this background, we proposed to investigate which creative processes need to be passed through in order to positively affect service development based on the role of the user in early stages of Internet service development. This case study was undertaken based on two new projects. The results of this study reveal the relationship between the knowledge creation process and user in early stages of development and at the same time provide guidelines regarding user involvement in actual service development.

Human desires start from the factors that make up the basic living environment. The development model of the safety guidelines will start from a sense of departure from collective psychology and systemic environment, at the time of inducing threats to threats. The design and methodology of the safety guidelines should be drawn up repeatedly by the sequence of iterative models, and the design methodology should be designed in the chronological order of the public services through the methodology of service design methodology. Various and complex threats attempt to derive insights from the user's perspective and to derive insight into the development of the safety guidelines and the sophistication of the user experience, and to extract insights from the perspective of a user's perspective and supervision model. This derived insight can be implemented as a multi-dimensional service model derived from the same problem consciousness methodology.

Purpose: This research aims at quality improvement of website services on the internet. Methods: SERVQUAL is redefined for web environments as sixteen statements in five dimensions to identify user requirements for websites and measure their importance ratings. Quality Function Deployment (QFD) is used to integrate user requirements into service development for websites so that management and design guidelines can be obtained for user-oriented websites. Fuzzy set theory is introduced to resolve the ambiguity and subjectivity of user requirements in the House of Quality (HOQ). Results: The priorities of design characteristics are extracted from the Fuzzy QFD for University websites. Conclusion: It is expected to provide quality services in less time with less effort, if the results of the Fuzzy QFD are used to provide services in a strategic way under limited resources.

With the perspective of information management, on-going monitoring of the specified service function is one of the major activities and even critical process. The research consisted of three empirical research questions such as, the current usage and overall user-satisfaction, the quality of the R&D information content and the service, and the problems which have been observed by the actual user group of National Digital Science Library (NDSL). The results of the investigation provided several guidelines that can be utilized for the improvements of the R&D information user service as well as some recommendations for overall optimal administration.

The purpose of this study is to elicit influential factors on accepting IPTV services and define the casual relationship between the factors, and "user satisfaction", "re-use intention", "stranger recommendation intention", in an attempt to provide useful guidelines to IPTV carriers, contents providers and equipment makers for their forming IPTV service models and marketing strategies. For this end, the theoretical background of this study has been brought from relevant literature, and theoretical study models have been established by logical reasoning of the interrelation among diverse components. Then, the established models have been analyzed by using statistical packages "SPSS(12.0), LISREL(8.72)". Finally theoretical and practical significance and future study direction have been suggested. To make sure of effective validity of IPTV service adoption models above, empirical studies should be made continuously. And then vertical and horizontal studies at a specific point would show ever-changing causal relationship, helping to promote financial outcome of relevant companies and organizations.

With the popularization of smart-phone, a variety of application service user is a rising trend now. In contrast, studies concerning library application service that cast a long shadow over the life of students and citizens still lacking in many ways. This study evaluates user experience of Young-in Si public library application service, and investigates user requirements. I searched the real user reviews about Young-in Si library application both App store and Android market. As the final outcome, I found inconveniences and improvements of this service. The application is intuitive, but requires consistent design, strong identity and customizing main page. It will be suggested specific guidelines for the public library mobile services in other areas.
