Web casting has become an important opportunity to apply the user-centered concept to broadcasting because it provides real-time interactive service through time and space. It is also necessary to have a new understanding about user who is not a passive viewer any more but an active user. The amount and quality of contents are also important, but usability is a competitive factor as well as the fundamental customer services that have user best experience at the site. Nevertheless most of web casting sites show the low level of usability. In this study we had a comparative evaluation among these sites, MBC, KBS and SBS, which are the representative broadcasting systems. The tests were carried out as heuristic evaluation and usability testing. We analyzed causes and problems of web usability for customer satisfaction and reliability exaltation, and expected the basic knowledge of developing and improving sites.

In this study, we present a usability test model that combines Concurrent Think Aloud, performance measurement, coaching method, and remote test method. Testing target was the consortium website of electronic information joint licensing. Test participants were actual users selected by their task roles and proficiency in different levels. We improved the system by reflecting the results of user test analysis and re-tested usability test again. The result showed that usability of all participants was improved in the aspect of the time required and the complexity of mouse trajectory. It is expected that the usability test model presented in this study can be used to cost-effectively evaluate and analyze business web sites.

The purpose of this study is to implement evaluation on domestic cyber University web site to analyze web usability and web accessibility in order to present how much cyber University provides various personalized services and qualitative contents to users on web site. And also with this result, I hope to contribute in qualitative development of web site and reliability of remote education. For this purpose, I developed checklist suitable to remote University by applying SM-ABCDE assessment method of Moonhyeongnam, the professor in Sookmyung Women's University, and implemented evaluation on web sites of 17 cyber University over the five aspects of attraction, business, contents, design, and engineering. As the result of this study, it was found that Busan Digital University was best in the respect of attraction, both Kyunghee Cyber University and Cyber University of foreign studies were best in the respect of business, Kyunghee University was best in the respect of contents, and Hanyang Cyber University was best in the respect of design. It was also evaluated in the comprehensive view and the order was found that Kyunghee Cyber University, Busan Cyber University, and Hanyang Cyber University. However in the respect of engineering, it came out that all the sites did not observe the regulation on web accessibility. If domestic Cyber Universities are to observe the regulation on web accessibility with the long term view, on the base of this study, web usability would be increasing. Then they can secure various classes of customers as well as ordinary people so that they will be able to take the real place of educational institution orienting the most advanced educational method in the society of knowledge and information in addition to advance in themselves.
