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.

Currently, obtaining information about the interior design studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. This study focuses on web-site uses in the interior designs' business. To process the study, a two-step research was executed; The step 1 was to find out the current status of web-sites by asking the each panelist to submit the monitored results after having searched and tested for more than two sites that was executed during the October, 2001. The analysis was made with the 47 sample sites selected from the monitored sites. And the step 2 was to find out the contents and evaluation factors of web-sites related the interior design. The results of the study are summarized as follows: First, the monitored Intoner design related 25 web-sites were classified into 3 groups. One group of 13 sites is identified as a remodeling/construction works, and one another with 7 sites is as shopping site, and the other with 5 sites is as a professional portal site. Second, the evaluation has been implemented which has shown 5 variables on the information searches are $\circled1$ the diversities of contents, $\circled2$ the accuracy/reliability of techniques, $\circled3$ the design of a picture and communication, $\circled4$ the convenience of link, and $\circled5$ the originality of web-site This study will provide the users with a fundamental material in evaluating the quality of interior design information on the internet web sites.

This study analyzed the teaching and learning support web services of health-specialized colleges. It was searched for educational innovation and teaching and learning support on the portal site. Web services related to teaching and learning at eight health-specialized colleges were classified into five categories. CTL web service support, teaching support, learning support, CTL introduction, and differentiated web services were analyzed. Teaching and learning support and CTL introduction web services were subdivided and operated, and web services that increased access to teaching and learning support were provided to teachers and students by preparing for national exams. Students at health-specialized colleges must pass the national examination to get a job, and the quality of teaching and learning needs to be improved. Therefore, the excellence of providing teaching and learning programs is required for junior college teachers and students. Based on this study, it is expected to improve the quality of web services for teaching and learning support in specialized health colleges.

Computational grids are emerging as a new infrastructure for internet-based parallel and distributed computing. Grid systems are enables the sharing, exchanging, discovery and aggregation of resources which distributed multiple administrative domains, organizations and enterprises. Accounting information service is one of the main obstacles to widespread adoption of the grid. But, most of grid portals do not support accounting information service. In this paper, we design an accounting information service and build a web-based grid portal including account management service and accounting information service.

Korea is one of the most advanced countries in terms of nation-wide readiness for conducting complex trade processes in an electronic way. Since various trade processes are well-known for their complexity and cost as well as time consuming characteristics due to required collaborations with involving parties, automation and efficiency are always the main concern of trade-related practitioners. Using information technology can be a possible solution to this problem and Korea has developed the national e-trade infrastructure called "u-Trade Hub." In this paper, we propose the framework to enhance the national integrated e-trade system called "u-Trade Hub," which is ready to be released for commercial use in near future. We propose the framework to upgrade u-Trade Hub in four directions: (1) opening, (2) strengthening community feature, (3) modularization, (4) seeking profitability. In this paper, we study and compare national e-trade environment of other countries such as Singapore and Japan. Then, we analyze and design the enhanced e-trade infrastructure based on Web 2.0.

최근 복합적인 기능을 가지고 있는 스마트폰의 확산으로 모바일 웹 시장이 빠르게 확장되고 있다. 모바일 웹은 데스크탑PC 웹과는 달리 화면이 작고 사용자가 손으로 아이콘을 선택하기 때문에 사용자들이 데스크탑PC 웹에서 사용하던 아이콘을 그대로 모바일 웹에 적용하여 사용하기에 모바일 웹서비스를 위한 GUI디자인의 연구의 필요성이 제기되고 있다. 본 연구에서는 데스크탑PC 웹과 모바일 웹의 아이콘 분석을 위하여 이론적 고찰과 함께 국내 포털사이트 5곳-구글, 네이버, 다음, 야후, 파란-을 대상으로 데스크탑 PC 웹과 모바일 웹의 아이콘을 내용방식과 표현방식으로 비교 분류하였다. 아직 모바일 웹의 아이콘을 데스크탑PC 웹에서 사용하고 있는 아이콘을 그대로 사용하는 포털사이트들이 많았지만 몇몇 포털에서는 모바일 웹 사용자를 고려하여 아이콘을 별도로 제작하는 사례들을 볼 수 있었다. 즉 모바일 웹의 사용성을 높이기 위해서 사용자가 작은 화면에서 아이콘을 보고 선택하는 사용 환경을 고려한 GUI디자인이 필요하다는 것을 알 수 있었다.
