This paper reports results of a recent survey of 184 Information Technology (IT) development practitioners and 90 User Interface (UI)/usability practitioners. This survey covered a broad range of issues including the respondents' profile, current development environment, usability and user-centered design (UCD) adoption issues in IT development practice, overall assessment of usability/UCD, and the most widely used usability/UCD methods and techniques. The results of this study are expected to provide an empirical basis for usability and UCD planning, training, adoption and execution in IT industry.

Eight dimensions of quality suggested by Garvin are well-known. It can serve as a framework for strategic analysis to obtain leverage of quality in a competitive market. However, some practically important dimensions such as usability, cost, etc. are not included in the Garvin's. Based on a survey of newly introduced products, we suggest another framework for dimensions of quality: function, time, limitation, usability, problem prevention, economy, maintainability, nativeness, These dimensions are explained with examles.

Usability heuristics("heuristics") are general principles for usability evaluation during user interface design. Our ultimate goal is to extend the practice of usability evaluation methods to a wider audience(e.g. user interface designers and engineers) than Human Computer Interaction(HCI) professionals. To this end, we explored the degree to which Jakob Nielsen's ten usability heuristics are understood by professors and students in design and computer engineering. None of the subjects received formal training in HCI, though some may have had an awareness of some HCI principles. The study identified easy-to-understand heuristics, examined the reasons for the ambiguities in others, and discovered differences between the responses of professors and students to the heuristics. In the course of the study, the subjects showed an increased tendency to think in terms of user-centric design. Furthermore, the findings in this study offer suggestions for improving these heuristics to resolve ambiguities and to extend their practice for user interface designers and engineers.

Purpose: This methodological study was done to develop a computerized telephone triage and consultation system for patients discharged with ophthalmic disease in order to provide more efficient practice guidelines for nurses, and evaluate the usability of the system. Methods: Development of the system consisted of six phases: strategic planning, analysis, design, implementation, evaluation, modification, and maintenance. Results: In the strategic planning phase, ophthalmic problems and nursing interventions of triage algorithms and practice guidelines were cross-mapped with the Omaha system. In the analysis phase, users requirements were identified. Then infrastructure including database, nursing knowledge base, and user interface were designed in the implementation phase. Usability and satisfaction of the system presented as very positive. Telephone consultation took about 2 minutes less than time in the previous system. The system was modified based on users' comments during the evaluation phase. Conclusion: This study was the first attempt in Korea to develop computerized triage system to prompt the quality of telephone consultation. It is suggestive that the computerized triage system may improve the quality of nursing.

Usability heuristics("heuristics") are general principles for usability evaluation during user interface design. This method is commonly used by Human Computer Interaction(HCI) professionals; however, the most widely used set of heuristics which were originally created by Nielsen has not yet been found practical in the current state of Korean technologies. In our prior research, we found that some of Nielsen's heuristics are difficult for some evaluators to understand and insufficient to fully evaluate Korean applications, due to the broad-applicability of these heuristics and differences in cultural context. Therefore, in this study, professionals in computer science and related fields evaluated Nielsen's ten usability heuristics in order to gather logical bases for finding areas for improvement. The results of this study will help creating a new set of heuristics that will better valuate more recently developed applications.

The change of digital convergence service environment converted the subject of design into user -centric one instead of developer-centric one, and changed the existing design environment focused on product development into the new user -centric design environment. Accordingly, GUI considering user's usability come to take big shares in those contents being used for multimedia equipments. However, as the present educational contents provide complex interface due to its design produced based on the existing e-learning system, they have many problems in that they don't consider user's usability. Thus this paper aimed to analyze actual examples through GUI elements of educational contents being used for multimedia equipments and attempt to suggest some directions for development. additionally, consider the various characteristics of digital convergence environment and educational contents, and try to set up strategic directions possible to utilize user'-centric interface elements more usefully and properly at the time to produce designs.

The Internet marketing of hospital is being considered as a strategic requirement that can satisfy the customers. Therefore, it is very important to understand the effects of the medical information on the Internet on the actual consumers. In this study, the paths through which the attitude and satisfaction of the medical information consumers that visit hospital web site are formed for the medical information through the quality of the medical information on the Internet and usability of hospital web site were examined respectively according to the medical examination and treatment subjects that respectively deal with medical acts and cosmetic acts through light metabolism recovery. The usability of hospital web site, rather than medical information quality, had positive effects on the attitudes toward the medical information distributed in the corresponding web site and the satisfaction of use of hospital web site in the case of visitors of the hospital web site for the medical examination and treatment subjects of essential medical examination and treatment and emergency medical treatment, and, on the other hand, the result of analyzing the path of the medical examination and treatment subjects of cosmetics and functional improvement revealed that the medical information quality had positive effects on the medical information attitudes and the usage satisfaction of hospital web site. Accordingly, the attitudes toward the medical information distributed through the web site by the visitors of hospital web site is formed from the quality of medical information and web site usability, and, ultimately, they become generally satisfied with the hospital web site. Such process is revealed different1y according to the medical examination and treatment subjects for which consumers desire to obtain information.

This study was intended to point out the limit of existing digital content-centered studies, or approaches from the viewpoint of the supplier and in the aspect of business profit model and find ways to assess the quality of digital content, considering the characteristics of digital content. For this, the study is to apply value innovation strategy to digital content assessment, to analyze the applicability, and to propose a new and practical framework for digital content assessment method. To this end, this study selected the global No. 1 search service provider Google and local portal site Naver search service. The study on assessment factors by value innovation strategy was based on existing literature, while user-value elements in that respect were confined to information quality, interactivity, communication, interactive storytelling, and usability. This study objectified the relation with the value innovation strategic analysis, through qualitative and quantitative analyses on value elements of search service users.
