With the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.

There have been many suggestions of ontology-based semantic web service systems and recommendation systems, but there has been no attempt to study educational consultation. Thus this study set out to tackle the problem and design specialized service to reflect individuals' interest, aptitude, hobbies, and grades based on the semantic web technology so that they could search the related information easily by managing personal profiles and identifying the meanings between information. It also aimed to suggest a convenient information service system of personalized educational consultation.

Most people choose Internet search engine first more than the library for their information search in these days. Many users do not know library homepage's content. How to improve the users in library homepage? This study aims to suggest the direction of library homepage service in Web 2.0. For this study the author analyzed library homepage that is introducing some representative Web 2.0 and other Web 2.0 sites. AJAX, RSS, Open API, MashUp, Wikis, Blog are the main technologies in Web 2.0. Those technologies become a tool that can do user centered library homepage. But, more important thing is information production that introduce to users. Web 2.0 suggests good information transfer for users. It needs to produce the information that stimulates the library user. It means that Web 2.0 give a good opportunity for libraries as an information production.

A PDA has limitation of storage space and inconvenience of Pen-based equipment to input. To solve these problems, this paper implemented that previous Speech Recognition provides using XML(extensile Markup Language) Web Service and PDA Client is possible to use speech command by request Speech Recognition Web Service. This system consists of Mobile Client and Speech Recognition Web Service Provider. The Mobile Client transmits user information and speech data to the Speech Recognition Web Service Provider using DIME(Direct Internet Message Encapsulation). The Speech Recognition Web Service Provider returns recognition results and user name only to an authorized Mobile Client. So We are able to use speech service without installing Speech Recognition or Speech DB in PDA.

Cloud computing emerges as a new computing paradigm which targets reliable and customizable services. The term builds on decades of research in virtual machine, distributed and parallel computing, utility computing, and more recently networking, web service, and software as a service. In this paper, we provide a seamless connection migration of web services. This is useful for cloud computing environment in which many client terminals have mobility. With the wireless internet facility, those mobile users can move place to place during internet communication. Therefore, we provide solutions to the two major problems in current virtualization based migration: communication failure problems and connection re-establishment. Communication channel flushing by zero window notification helps to resolve the communication failure problems and TCP port inheritance prevents connection re-establishment errors during socket reconstruction. Thus, our web service migration facility is now able to preserve open network connections, and even for server sockets. This is a highly transparent approach, in that we did not Introduce additional messages for channel flushing and did not make any modification to the TCP protocol stack. Experimental results show that the overhead due to connection migration of web services is almost negligible when compared with time to take the conventional web service migration.

Korea-China with the fastest speed Internet Broad Band, has achieved many progresses on Internet shopping. Especially, Korea has made a great effort on comparison website construction. A research prototype design and exploratory analysis are presented to assess success factors and impacts of Korea and China price comparison websites. For different user groups, the relationships between the characteristics of technology and tasks, usage, and organizational impacts were analysed. It shows us how to improve the applicability of fit-viability of the price comparison web sites in China after analysis. These results indicate a need for simple but highly functional price comparison applications. And we designed a sample model to include an interactive web service system for price comparison sites that complement existing information systems. This paper provides a basis for further research aiming to improve the design and management of business applications based on emerging technologies of web service and browser for information management.

With the evolution of Internet technologies and the increasing variety of Internet devices, advertisements in various web services have also expanded. Interactive web services often go hand in hand with effective advertisements for a business model. We estimated statistical parameters of the interactive web server for service monitoring and advertisement-effect. In the web pages, we integrated the plugins of social networking services (SNSs) (e.g. Facebook, Twitter) and an advertisement scheme (e.g. Google AdSense) that regards social name-directory contents. Empirical data analysis and statistical results are presented with the implementation of estimations of parameters (e.g. utilization-level and serviceability) and advertisements in a social networking name-directory service (http://ktrip.net or http://한국.net). We found that estimated parameters were applicable to service monitoring of web-server as well as to synthesis of advertisement-effect in our social-web name-directory service.

Due to the development of Internet and networking technologies, it is much more easier to get in touch with public service through the web services such as tax, travel information, getting a job, etc. In order to measure the quality of official government web sites, we are to test the difference between the web quality of the government sites and the offline feature of the same official service by means of customer perspectives. The resulting of this study show that the quality of official web site has been improved so far though such areas as privacy, security needed to be updated. Especially the web interface or contact point of the digital media should be reflected customer's need so that the online materials may be quickly updated according to the request of client's.

National Records Designation System is designed to protect valuable civilian records from loss or damage. It also intends that government administrates important civilian records to raise public concerns civilian records and to foster archival culture in Korea. This study investigates the current states of service fo the designated record through the web page of National Archive of Korea. Major findings are as follows. First, the information of designated records is dispersed in two web pages by the National Archive of Korea, an introductive web page of every collection in the National Archive of Korea and a web page of designated record service. Second, the web page of designated record service provides information of designated records only at collection level, so it is not easy for users to understand the contents of the records. In order to improve the service for the designated record service of the National Archive of Korea, this study proposed the unification of dispersed web pages to provide information of the designated records consistently. It also suggested a facet based directory service and word cloud service to give access to the contents of each designated record collection. The facet based directory and word cloud service will help users to understand the designated records in more detail.
