ABSTRACT The purpose of this study is to identify possible needs for sys tem improvements and reflect them on the operation and development of the system as a result of the usability assessment of an information site in science and technology. For this stud y, a variety of data collection techniques, including search logs, interviews, and think-alouds , were used. The search log data was processed to quantify four evaluation aspects, which were t he effectiveness, efficiency, satisfaction, and errors. The verbal data collected by think-al ouds and post-interviews were used to identify possible needs of enhancement in a qualitative analysis. The comparison of the usability before and after the system enhancement revealed an increase of 15 points for effectiveness, 35 seconds decrease in efficiency, 5 points incr ease in satisfaction, and 1.1 errors decreased, implying an overall improvement of the usability of the current system. 키워드: 웹사용성, 국가과학기술정보시스템, 검색로그, 씽크 어라우드, 이용자연구Web Usability, National Science and Technology Information Syst em, Search Logs, Think Alouds, User Study
