This research is carried out being divided into a first evaluation and second evaluation. A Study is carried out on first, the accessibility compliance level of Korea government department websites and second, whether the site which complies well with web accessibility increases web usability for users through a web usability evaluation. The evaluation result, web sites which comply well with the web accessibility guidelines were observed to increase web usability for both normal and disabled people but web sites which do not comply well were observed to lower the web usability making the web sites unavailable or inconvenient to use. Therefore, it can be concluded that there is a very close interrelationship between web accessibility and usability and thus compliance with web accessibility is not an option but a mandatory requirement.

The present study examined the usability of the web site design, focusing on the cognitive characteristics of the WWW. Specifically, we conducted two major non-experimental usability testing methods on the domestic web sites with various purposes. In research I. we used an on-line questionnaire method on 12 domestic web sites. As a result. several critical usability features and factors were identified. In research 2. we carried out a heuristic evaluation method to identify more specific usability problems The result of research 2 suggests that the heuristic evaluation method reveals more specific problems of the web site design than the questionnaire method.

The interaction between web site and it's user is more active and free than that of any other interface environment. Consequently, it is very important that user interface environment must be fully considered in web site development process. In this study, first, web interface environment and it's features are examined, then web usability test techniques are analyzed, and on the basis of the results, new tool for visualizing various responses and patterns of web site user is developed. Finally, by applying newly developed tool to usability test process of an internal hub site and analyzing the results, effective methods for visualization and evaluation of using patterns of web site are suggested.

Most research on web site design has focused on technological factors, while visual aesthetic factors have been considered less important. In contrast, this study focuses on visual aesthetic factors in web site design. Findings of this study can be summarized as follows : (1) The result of SPSS-factor analysis shows that there are 3 distinct factors, 'classical aesthetics', 'expressive aesthetics', and 'usability' 'Classical aesthetics' and 'expressive aesthetics' can be described by visual aesthetic design, 'Visual aesthetic design' can be distinguished from 'usability'. This conceptual confusion relating to 'usability' and 'visual aesthetic design' can be clarified by these findings. (2) As a result of multiple regression analyses, 'classical aesthetics', 'expressive aesthetics', and 'usability' have a positive influence on 'interactivity' and 'web site evaluation'. This research clarifies the concepts of 'expectations' of Grier [18] and 'engagement' of Rosen and Purinton [33] as the 'interactivity' between users and web sites. Furthermore, this research suggests a valid model with high $R^2$(interactivity, 48% : web site evaluation, 68%). (3) Empirical tests show that the differences among users in 'entry point' are related to the characteristics of web sites and the personal characteristics of users. The differences among users in terms of 'scanning time' are closely related to the attitudes and evaluation tendencies of users with respect to web sites. These findings could contribute to the 'search phase' of the Faraday model [16], enabling it to be more precise and extensible. The managerial implication of this study is that customers' preferences regarding web site designs are differences, as their preferences are based on their individual characteristics. Therefore, marketing managers should consider promotional tools on web sites that are relevant to the target market. An optimal strategy for web design could be a carefully-selected combination of factors that are relevant to the 'interactivity' and 'evaluation' of web sites. Additionally, if marketing managers want to attract more favorable attitudes and more affirmative evaluations from users, web sites should be designed so that they are understood more quickly by users. finally, this study suggests that 'good design' for web sites depends on understanding how to attain the appropriate balance between 'classical aesthetics' and 'expressive aesthetics', based on the target customer.

The present study employed an experimental usability testing technique to explore cognitive engineering characteristics of WWW. Based on the results of our previous study which employed non-experimental methods such as questionnaire and heuristic evaluation method, this study used a behavioral performance-measurement technique to evaluate the usability of a domestic web-site design. Specifically, we revised the menu and document structure of the original 'Movie-Friend' site to solve the design problems which were extracted from the results of the heuristic evaluation method of our previous study. Exp. 1 compared the relative navigation efficiency of the original frame menu site and the revised pop-up toolbar site, and Exp. 2 compared the toolbar menu site and the revised frame site. As a result of Exp. 1, the revised pop-up toolbar site showed improved navigation efficiency compared to the original site, as indicated by the mean latency and the number of pathways to reach the target page. However, we found no performance difference between the frame site and toolbar site in Exp. 2.

In this paper we evaluate the Korean e-government portal and linked web sites, based on usability. We pick a set of 18 representative government sites, and consider two approaches of type-I and type-II testing with different questionnaires. We ask users two questions at each site, regarding simple facts. We count a task as successful if the user find the right answer for fact questions. In type-I testing, after users have finished working with a site, we give them a post-test questionnaire asking them to rate the site in 16 different areas, in order to calculate the site rating. In type-II testing, we investigate page design, contents design, and site design of the web sites.

The previous studies regarding the usability evaluation of e-government web sites focused only on deriving affecting factors and variables. They did not find the relationship of usability, user satisfaction and revisiting. The objective of this paper is to find the causal effect how the usability of e-government web sites affect to the user satisfaction and the revisiting attitude. no scope of e-government web sites included the portal site and ie liked web sites. We developed a structural equation model and performed a user test. As a result, a perceived usability affected the revisiting, but it did not intermediate the user satisfaction.

In this study, we evaluated web usability for hospital web sites in Korea and analyzed the evaluation results of web usability. Estimators investigated twelve hospital web sites and answered a questionnaire. They also performed predefined tasks which were frequently used services in hospital web sites. We had an interview with the estimator for finding what happened in process of evaluating usability. The evaluation results showed that university hospital provided comparatively better web usability for users. But ambiguous and complicated user interface caused confusion among users. The simplifications of service processes and interfaces were necessary to improve web usability. Some hospitals did not offer primary web services and their services related to the tasks were not systematic.
