According to the rapid growth of Internet service, electronic commerce usage scale is growing every year. It requires the method of vitalizations of electronic commerce through reducing the software development cost and making easy of data construction. Web service, which is adapting distributed technology based on internet supports the infrastructure of reducing the software development cost through software sharing. As the shared software modules access the same data, they can reference the same data on the other site. In this paper, we designed and implemented database Processing module of the electronic commerce program using web service technology, which can make easy of site construction and sharing database. Implemented database processing module supports data selection modification insertion deletion and searching. Using this functions we showed product item information could be shared among the other electronic commerce sit.

Purpose: This study was conducted to develop a Web-based learning program on cardiopulmonary emergency care for clinical nurses and to evaluate learners' responses. Methods: Based on the assessment of learning needs of clinical nurses, a total of three self-directed learning modules were developed according to the procedure of the ADDIE (assessment, design, development, implementation, & evaluation) model. Results: Each learning module included the emergency treatments and drugs used in the real patients' situations with cardiopulmonary crisis, which had been adopted from the emergency department of a C University hospital located in G-city. Real video clips for endotracheal intubation and ACLS (advanced cardiac life support) were developed with the help of the staff of the department of emergency medicine using a human simulator, $SimMan^{(R)}$. The program published on the Web was evaluated by 20 clinical nurses who are working in the emergency department and wards of a C-University hospital. About 80% of the respondents were satisfied with the program contents, design, and learning strategy. Conclusions: Web-based learning programs on cardiopulmonary emergency care are needed for clinical nurses as educational material for staff education to increase their knowledge for making immediate clinical decisions and in giving skilled care in emergency situations.

The design process of RC Slab includes multiple procedures such as structural analysis, member design, the production of calculation sheets, CAD, and itemized statements of quantities. The objective of this study is to develope an integrated design system that includes all the steps needed for RC Slab design, and as a result, to improve the quality and efficiency of the design process. In this study, the design steps are divided into structural modules and database, and each module and database is systematically combined for the complete design process. The developed design system is based on Web environment. Therefore it can be used in real time and reduces the design work time and space.

Recently, many kinds of XML based application services are widely used in internet. And the markets for mathml editor are needed for the technology combined with other text editor. We are developing a system for MathML based browser and editor for the service of internet application. MathML based browser is applicable for e-book service and many kinds of document system. This system is composed of document editing module and displaying processing module. This system is useful for the processing of MathML tag by unexperienced users with MathML syntax. Users can edit the math tag's document with ease and efficiently. Based on XML, many parser functions are optimized for the speed of document processing. This system can afford to the development of internet world.

This study is to identify whether three types of online instruction (text-based, video-based, and video-based instruction without text) and age category have a different influence on students' comprehension and motivation. Online students were randomly assigned to one of six groups, and they attended two-week online lectures via Course Management System. The comprehension test and the short form of IMMS were implemented when 114 participants accomplished two-week online lectures. The results revealed that using instructional video in online instruction is more effective instructional medium than text only in order to promote learner's motivation. Besides, older adults aged 41-60 are significantly different from younger adults (21-40 years old) in terms of students' comprehension. Furthermore, three types of online instructions are likely to be influenced by age category.

As the result of the rapid development of communication technology makes the circumstance and method of education change, distance education is adapted to new fields of education so that students can be educated what they need in the time and space which they want instead of relying on the existing physical frameworks. In this paper Learner-Analysing System was designed and implemented in the distance education based on the web. For the easy access and the demand of customers, this Learner-Analysing System is composed of the Q&A-processing module which can produce proper results for questions and acquisitions of their own study materials through efficient search, and the student-analyzing module for reinforcement of feedback through correct analysis.

In order to provide efficient retrieving results for user query on the web environment, the various searching algorithms have developed and considered user's preference and convenience. However, the searching algorithms are developed on the horizontal and non hierarchical web environment in general and could not apply to the complex hierarchical and functional web environments such like the enterprise network. In this paper, we purpose the multi-agent based web mining system which can provide the efficient mining results to the user on the special web environment. For doing this, we suggest the network model with the hierarchical web environment and model the multi agent based web mining system which has four corporation agents and fourteen process modules. Then, we explain the detailed functions of each agent considered the hierarchical environment according to the module. Especially, we purpose the new merging agent and improved ranking algorithm by using the graph theory.

System analysis programs have been developed by several different research groups. Especially, the programming languages and the developing environments of algorithm modules and user interface modules are different. And therefore, the differences have degraded interoperability and reusability of the system analysis modules. in order to solve this problems, a general binary interface has designed and the component based on the interface has developed as well. However, sometimes each interface is uncompatible because those are designed on the particular vendor. In this paper, we deals with XML web service, Sort of distributed processing architecture, which is not restricted by not only the existing internet standard but also any Programming language or any vendor. Because of its platform independent, each module can be updated and extended independently.

This paper describes the development of a brickwork game with three-dimensional computer graphics as one of web-based game contents. Client user using web can access and run lava applet program with the independence of hardware system. It consists of graphic user interface module, initial space generation module, event handler module, player control module, and thread control module. It uses 3-D array data structure for the 3-D graphic objects that are located in three-dimensional space for high-speed object searching and sorting. It enhances to compare with predetermined construction in three-dimensional space. We can use the developed racing game to inform game users of information for an advertisement like tourism information, and can apply the proposed 3-D drawing technology to 3-D game graphic engine core.
