One of drawbacks of the current edutainment game system is that its frame is fixed with limited contents. Under the condition of the above game structures, nobody can select one's interesting contents to increase educational efficiency easily. To overcome such a problem, we will propose the system named UCG(User Combinative Game) based on Web 2.0 in which users can make a choice among various educational contents and select game frames. The structure of the UCG system and its process are shown in this paper.

Recently, RESTful web service is getting attention with the emergence of Web 2.0. The main advantages of REST web services are lightweight and easy implementation compared to SOAP based web services. In order to define and describe RESTful APIs, various methods have proposed. WSDL 2.0 can describe both SOAP-based and RESTful services and but it is too complicated. WADL is championed by Sun Microsystems and it is lightweight, easier to understand and easier to write than WSDL. The purpose of WADL is to allow web services to be described in a machine readable way, to make it easy to create Web 2.0 applications and create a dynamic way of creating and configuring services. However, WADL does not provide utility tools to generate client code automatically and the developers describe client code manually. In this paper, we design and implement a WADL2Stub system to generate client code from WADL files automatically so that the developers use REST web services to easily and conveniently.

Recently, web 2.0 is becoming issue can provide a web based services and the technology is developing rapidly. In addition a variety of platforms on the web and SDK(Software Development Kit) is available from various aspects, web services, a trend that is rapidly growing user. But the development of security systems cannot follow the speed and These weaknesses are provided in the Web service by using illegal methods of information acquisition. Therefore, in this paper, we analyzed information for checking a variety of illegal access on Web services. Also, we designed and implemented Web Service-Hacking Pattern Recognition System for which warns the dangerous fact that as recognized hacking through comparisons the hacking patterns which have classified from the hacking method of existing system.

As data broadcasting has become available, diverse contents can now be provided through digital TV, IPTV and DMB; yet it is true in the current situation that killer contents are insufficient that can satisfy users. On the contrary, in case of the web, with the advent of web 2.0 aiming at user-centered services, the contents market has grown greatly. The ideas and technologies of Web 2.0, if gratified into data broadcasting, are expected to make a contribution to the vitalization of contents. This paper proposes a method of using RSS, as a concrete example of applying web 2.0 to data broadcasting. Accordingly, we have developed a system for producing data services for the ground wave DMB data broadcasting, by using RSS at the stage of authoring news and the like, for which provision of the latest information is important. And for IPTV, we have developed a data broadcasting application so that users can select the RSS they want, as well as a creation system for using RSS at the authoring stage. It is anticipated that the application of RSS by means of the system will simplify the authoring process, making easy the provision of the latest information through the web, and thereby making possible the provision of diverse services to users.

Recently, it is to increase rapidly in people who do a private business through Web service. So, many companies have been developing part of businesses using Web Services. The greatest interest of companies developing Web Services was that users were easily discovering and using information on theirs. So, companies have been taking interest in a standard that supports registrations of information on Web service and discoveries of a registered Web services. Therefore UDDI 3.0 standard of the registry for Web service standardized by OASIS is in the spotlight. But, because of the complexity of it, there are no implementations developed in the inside of the country yet. And a development activity of it is faint. In outside of the country, IBM, Microsoft and SAP has developed it, but they do not perfectly support a standard of UDDI 3.0. This Paper shows the development of the Registry System which supports perfectly a standard of UDDI 3.0.

In the era of Web 2.0, users create a number of their own Web contents. So, multimedia search becomes much more important than ever. A tag is a simple keyword which describes the Web contents including URL, pictures, and videos. Tags perform a role of descriptors of Web contents and Web metadata properly. If the number of tagged Web data increases, users are more likely to find the desired search result because the system includes the Web contents which have richer Web metadata. However, the number of users who use tags as Web metadata is relatively small. Because of the cumbersome process of adding tags, or users do not know what to add for the better accessibility from the public. Given situation, tag recommendation, which helps the process of adding tags, has been studied to solve these problems. When a user adds some Web contents, the tag recommendation system recommends relevant tags for the Web contents to the use, and the user selects recommended tags. We analyze and categorize various tag recommendation algorithms in tagging system.

Recently, it is increasing the interest in previous web and web 2.0 which mean differentiation. The previous system is typical Static web based on client and server model, while web 2.0 mean next generation web which web change and evolve fundamentally. In this paper, I suggest that the module on RSS reader available under web 2.0 standards. A currently used RSS feed do correct the part distortion which can be possible resolve the encoding problem of Hanguel and third-world language. The suggested module is implemented using Ajax. I developed the module for the use of effective contents on web 2.0 through the DragBox module based on the programming on mobility of Ajax and the design and implementation of automatic update module of RSS feed.

In a web 2.0 environment, as a wide range of web services are being utilized, it requires quick and convenient way to develop web applications. For this purpose, the framework has been recently introduced and has been applied to web applications. However, software quality application model has not been presented for the web application using framework. In this paper, we develop web application, online library system using a number of frameworks. The system allows users to freely share book information. In order to evaluate the system, we present new software quality evaluation model for web applications using framework. The five quality attributes, functionality, usability, efficiency, maintainability, stability are defined based on the international standard for software quality evaluation, ISO/IEC 9126-2. We also propose the evaluation metrics for the web application using framework and perform quantitative evalzuation for the online library system.

In recent creativity becomes a new request in the knowledge and information age. Robot programming education is an effective teaching method for improvement of creativity. Existing robot programming tools includes text-based or GUI-based development environment. Most of programming tools provide a simple tutorial system without interactive activity for beginners. In this paper, we propose an online robot programming education system based on web2.0, which embedded collaborative code creating tool, interactive tutorial chat and video conference tool to support collaborative code creating via web 2.0. Knowledge sharing tool allows users to share their collaborative source code. Besides, it makes users gained the experience and knowledge of program designing efficiently.
