Recently, market of mobile spatial information service is increasing along with enlargement of geo-spatial information utilization area and spread of smartphone. In particular, smartphone users look forward to utilizing spatial information service more easily and conveniently. Korea has the potential for spatial information technology development, but does not have enough governmental support to develop various spatial information service in mobile network environment. Hence, it is need to make governmental support plans for utilizing mobile services and promoting the related industry base on mobile spatial information. In this paper, we propose governmental action plans for utilizing mobile services and promoting the related industry by surveying mobile application/web services and analyzing demands of mobile spatial information experts.

Automatic identification is pervasive in many areas and its applicable areas are increasing gradually. 2D bar-code, NFC, and RFID technologies are representative examples of the automatic identification. This paper explains the implementation of mobile tourism application software on RFID technology. The mobile application provides the location and navigation information by combining the tag inventory and web database. The interactions among the user, application and database server are described in detail. This paper proposes a simple way of minimizing the efforts to build the entire system by storing the URLs for the tag and accessing existing tourism information services through the URLs.

A standard Web server or web application servers require the Web Servlet container to execute SOAP messages. But it requires additional process to make web service modules and need communication port. Also, Recently many web applications is becoming increasingly demand against the dynamic document than the static documnet. But a recent study has found that Apache Web Server always does not show the better performance. The more it have the dynamic documents, rather it can show worse performance. To solve this problem, we propose a new High-Speed Message Processing System, in which the SOAP_MP and the WSDL builder are used. The WSDL builder convert HTML/XML to WSDL files automatically and the SOAP_MP minimize SOAP massage processing time by eliminating the Tomcat Servlet container in the mobile Web Services implementation. We compare and analyze the System, which was proposed by us, with the standard Web Service system.

XML Web Service is a new distributed computing paradigm for combining all computer systems through the on-line standardized open network, so it is expected that companies can get the results of increasing profits and reducing costs through this. Especially XML Web Service is essential in mobile environment. In this paper, a new XML Web Service is proposed and it is based on WIPI-based XML standard technology and mobile web service standard. The proposed XML Web Service embodied XML Parser which can be used in WIPI environment and made HTTP communication. In addition, as an example of the practical application, it was applied to an inventory Management, Book Store using JAVA language for WIPI.

This paper describes an application level composition mechanism called Generic Modeling Environment(GME) for web caching on an Application Level Active Network(ALAN). Web caching on an ALAN requires the application level composition mechanism and a service composition to support adaptability for self-organization. ALAN was developed to solve the problems of the network level Active Network(AN) ALAN has the features of both AN as well as mobile agents. The efficient composition mechanism for the existing AN Projects has been supported primarily for the network level AN. Conversely, ALAN lacks support for the application level AN The existing web caching technology is inter-connected in a manually configured hierarchical tree. Since a self-organization system is intended to be adaptive, web caching for self-organization does not involve a manual configuration or any low-level tuning of the individual nodes of the entire system but requires service composition to support adapting intelligence and fault-tolerance to enable self-organization.

Recently, the demand for mobile system is growing owing to the spread of smart phones to enable the real-time business process. This paper proposes the real-time facility maintenance management system using an android-based mobile application to apply to the facility defect/maintenance field for the apartment building complex. The proposed system model aims to develop the comprehensive management system to integrate the web and mobile system to lead to the realization of mobile office. The security measures required in the mobile system are technically analyzed and implemented on the system.

In this paper, we proposed an efficient document conversion mechanism to provide a adaptive web document to mobile terminals. We also proposed a RHTML(Reduced HTML) to archive the adaptive tag reduction. Markup error correction process in the proposed adaptive document conversion mechanism converts a HTML(HyperText Markup Language) document into a XML(Extensible Markup Language) application document. This. process makes web document easy to handle with a DOM (Document Object Mode)) as the tree model and removes the hardware overhead in mobile terminals. Also, tag reduction process provides the adaptive web document with three DTD(Document Type Definition)s in the RHTML.

For real-time social networking service, mobile interaction in a usable-unified-ubiquitous (U3) web service was studied. Both as a convenient mobile HCI for real-time social networks and as indexing keys to metadata information in ubiquitous web service, the multi-lingual single-character domain names (e.g. 김.net, 이.net, 가.net, ㄱ.net, ㄴ.net, ㅎ.net, ㅏ.net, ㅔ.net, ㄱ.com, ㅎ.com) are convenient mobile interfaces when searching for social information and registering information. We introduce the sketched design goals and experience of mobile interaction in Korea, Japan and China, with the implementation of real-time social networking service as an example of U3 Web service. We also introduce the possibility of extending the application to the metadata directory service in IP-USN (IP-based Ubiquitous Sensor Network) for a unified information management in the service of social networking and sensor networking.

Recently many applications are being developed as web technologies are evolved rapidly, but the development emthodology and quality improvement speed of the web apllications is not so. The creations of Most web applications have developed depending on the developer's knowledge and experience without a systematic development methodologies. But the web-based application systems require the various developing gechniques and the rich developing methodogies for a design process. This paper applies the UML(Unified Modeling Language) supporting an object-oriented development methodology to the design and implementation of a mobile customer management system. That is, it appliesthe UML to the system modeling based on a story board and a requirement specification at the web development of the similar web applications. Applying UML to this system achieved the analysis and the design of an web application effciently.

The development of smart technology has brought the conversion of closed traditional e-learning contents into open flexible smart learning contents consisting of learner-centered modules, without the constraints of time and space by use of smart devices from the uniformed and passive classroom between teachers and learners. It has been demanded an open, personalized and customized teaching and learning contents of smart education and training systems according to wide supply of various smart devices. In this paper, we discuss about the status of the smart teaching and learning systems and analyze the characteristics and structure of the web contents for smart education and training systems by use of smart devices. And we propose a method how to block web contents, to extract them, and adapt personalized segments of web contents by adaptive algorithm into smart learning devices. We extract blocks from the web contents based on the smart device information and the preference information of the learners from existing web contents without the hassle of learners environment. After specifying a block priority from the extracted web contents by the adaptive segment algorithm, it can be displayed directly to the screen to fit the individual learning progress of the learners.
