This research aims to produce and implement web-based continuing nurse education programs in response to nurses' educational needs, and to verify them, thus preparing for the times that the program will be offered via web. This research designed, produced and implemented 'emergency nursing' and 'medical fee schedule management' subjects based on Jung, In-seong's(1997) web-based instructional system design, and then compared the learning achievements of web-based learning group of 38 people with those of face-to-face learning group of 39 people. The questionnaire have been developed by these researchers to measure pre-learning knowledge on 'emergency nursing' and 'medical fee schedule management.' Data collected for this research have been given statistical analysis, using SPSS 10.0 for Windows Program. As a result of giving Mann-Whitney test, with respect to pre-learning prior knowledge level, there was no significant difference between the web-based learning group and the face-to-face learning group(Z=-.092, p=.926), while after completing learning, there was a significant difference in the learning achievements between the web-based learning group and the face-to-face learning group(Z=-2.406, p=.008). That is, this research revealed this: the web-based learning group and the face-to face learning group with both having no significant difference in the pre-learning level, after receiving the continuing education each with different methods(face-to-face education and web-based education), showed that the web-based learning groups attained higher learning achievements than the face-to-face learning groups. This result proves the effect of the web-based education to be no worse or even better than that of the face-to-face education, provided that choices of appropriate themes and quality courses composition, as well as systematic design development effective implementation are guaranteed.

Recently. many researches on the personalization of a web-site have been actively made. The web personalization predicts the sets of the most interesting URLs for each user through data mining approaches such as clustering techniques. Most existing methods using clustering techniques represented the web transactions as bit vectors that represent whether users visit a certain WRL or not to cluster web transactions. The similarity of the web transactions was decided according to the match degree of bit vectors. However, since the existing methods consider only whether users visit a certain URL or not, users' interestingness on the URL is excluded from clustering web transactions. That is, it is possible that the web transactions with different visit proposes or inclinations are classified into the same group. In this paper. we propose an enhanced transaction modeling with interestingness weight to solve such problems and a new similarity measuring method that exploits the proposed transaction modeling. It is shown through performance evaluation that our similarity measuring method improves the accuracy of the web transaction clustering over the existing method.

To improve performance, most of Web Services produce and manage User Access Logs. Through the Access Logs, the record provides information about time when the most traffic happens and logs and which resource is mostly used. Then, the log can be used to analyze. However, in case of increasing high traffics of Web Services at the specific time, the performance of Web Service leads to deterioration because the number of processing User Access Logs is increasing rapidly. To solve this problem, we should improve the system performance, or tuning is needed, but it makes a problem cost a lot of money. Also, after it happens, it is not necessary to build such system by spending extra money. Therefore, this paper described the effective Web Service's performance as using improved User Access Log performance. Also, to process the newest data in bulk, this paper includes a method applying some parts of NoSQL using Redis.

WebDAV is an IETF standard protocol which support asynchronous collaborative authoring on the Web. The recently published WebDAV Access Control Protocol provides various methods of controlling the resources on a WebDAV server and their properties, helping high-level group activities to be performed through the WebDAV server. Based on the WebDAV access control protocol, we developed Group Workspaces which support exchanging and/or sharing data among the group members. Any member of a Group Workspace can create and share resources among the members. Also, any member can add, change or delete the resources. To support the Group Workspaces, we developed a client application named GroupExplorer, which solely supports Group Workspaces. We constructed the server for Group Workspaces using Jakarta Slide - a WebDAV server supporting the WebDAV Access Control Protocol.
