To develop the broadcasting application for DMB, the programmers have to aggregate the content. In this case of content such as news, it would be hard to provide successively updated content. This paper introduces a creation system which can automatically create the news application for data broadcasting on DMB based on the web news content updated immediately. The designed creation system aggregates the news content using RSS based XML and produces the news application by transcoding the web content which can be applied on DMB.

In this paper, we presetn the WWW (world-wide-web) base dtelePACS, which uses the communication network as asymmetric satellite data communication system (ASDCS). Web-based telePACS is imple-mented with JAVA language. Through the internet, web-based TelePACS can make it possible for remote hospital or doctor to access PACS data and information easily and cheaply. The ASDCS uses receive-only satellite links for data delivery and PSTN (Public switched telephone Network) modem or N-ISDN (narrow band integrate services digital network) for communication. The satellite communication linking shows the very high-seed performance such as 10-30 times faster than the modem linking.To solve the speed limits of internet, JPEG and wavelet compression methods were adapted in WWW-based TelePACS and were evaluated by PSNR (peak signal-to-noise ratio) and by radiological experts that 10:1 or less JPEG and wavelet compression may be acceptable for diagnostic purposes. Consequently, we get the conslusion that our system is suitable for tele-radiology and telemedicine world widely.

In this paper, we proposed multimedia based ExamBank system in web environments. In the proposed system the database was designed based on the object-relation model and the application program was implemented with Java such that independent execution would be possible to guarantee no fault for multi-client in Web environments. We defined the Exam entities as objects, and implemented those inter-relationships as user definition and type. In addition, by mapping the schema object of DBMS and JAVA class, it becomes to possible transferring the object systematically between DHMS and JAVA application server.

The primary questions addressed by this research are the followings: Has the interface of a Web-based OPAC been improved more user-friendly; How about its searching abilities; What difficulties have Web-based OPAC searchers experienced in using a Web OPAC; How do they perceive the system after use of it. Finding the answers of those questions the problems of a Web OPAC as a searching tool have been grasped and recommendations have been suggested in order to improve the system. An experiment was conducted and 30 university students performed 8 searching tasks. The searching behavior of Web OPAC searchers has been analyzed thoroughly. The data of their perceptions about the system was collected through a questionnaire after completing the tasks.

The information available on the Internet has become widely used, primarily due to the ability of Web based E-Commerce and M-Commerce Retrieval Engines to find useful information for users. However, present day Commerce Retrieval Engines are far from perfect because they return results based on simple user keyword matches without any regard for the concepts in which the user is interested. In this thesis, we design and evaluate a Recommender system for web context aware based information retrieval using user profiles. Also, we designed personalization framework in ubiquitous environment based both e-commerce and m-commerce and presented the interaction of user profile including User XQuery pattern in semantic web.

This paper deals with how to apply PBL(Problem-based learning model) model to interdisciplinary field such as engineering accounting. The PBL approach can provide a solution about educational issue for engineering accounting with a systematic view. A web-based practice system, which is a core element of PBL model and a learning object and practical exercise for engineering students, is developed.

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.

One of recent trends in Web-based GIS is the system development using FOSS (Free and Open Source Software). Open Source software is independent from the technologies of commercial software and can increase the reusability and extensibility of existing systems. In this study, we developed a Web-based GIS for interactive visualization of geographic information using Google Earth and spatial DBMS(database management system). Google Earth Plug-in and Google Earth API(application programming interface) were used to embed a geo-browser in the Web browser. In order to integrate the Google Earth with a spatial DBMS, we implemented a KML(Keyhole Markup Language) generator for transmitting server-side data according to user's query and converting the data to a variety of KML for geovisualization on the Web. Our prototype system was tested using time-series of LAI(leaf area index), forest map, and crop yield statistics. The demonstration included the geovisualization of raster and vector data in the form of an animated map and a 3-D choropleth map. We anticipate our KML generator and system framework will be extended to a more comprehensive geospatial analysis system on the Web.

This study aims to implement an efficient process management system for small and medium sized(local) construction companies and a performance management system for the Korean construction industry. The process management system by Lean Construction is Web 2.0 platform-based and creates clusters with numerous general contractors and sub-contractors, which will enable mutually organic process management. Plus, this system will enable them to compare project performance management by analyzing it during or after a project by collecting and accumulating lots of data occurring in pursuit of a project. These performance management cases will be of help in process planning during similar upcoming projects. This study is expected to somewhat reduce the burden of implementing a complicated process management protocol and system that Korean small and medium sized (local) construction companies experience with their web-based process management, and is supposed to realize accurate performance management with highly reliable data which are significantly accumulated within the database.
