This paper proposes and implements a mobile service and web service integration for utilizing public bicycle sharing system NUBIJA. The NUBIJA system is operated by Changwon City, GyeongNam since 2008 and maintains 247 unattended bicycle sharing terminal on the city. Average users per day of the NUBIJA are more than 8,000 and many users want to get more services from their mobile phones. We implemented realtime mobile bicycle rental and return information service. The informations are acquired from each terminal kiosks and we integrated the information and location based services(LBS) on iOS and Android platform. In this paper, we described an integration services between web and mobile application and shows graphical user interface for highly customized on mobile platforms.

By introducing Web Services, distributed GIS services from different vendors can be dynamically integrated into a GIS application using the interoperable standard SOAP protocol. However, it is debatable whether SOAP can really meet the performance requirements of GIS. This paper presents an experimental evaluation of the performance of different SOAP variants: standard SOAP, SwA/MIME, and SOAP/MTOM. The objective of this paper is to demonstrate that SOAP performance in communicating large volumes of GIS data could be effectively improved by recent standards. Moreover, SOAP/MTOM is identified to be the fastest and the most efficient messaging protocol.

The standardization on RDD and REL has been developed by MPEG. REL is a Right Expression Language and RDD is term dictionary which develop active application of REL. However, since REL documents could be oかy edited by user understanding MPEG-21's framework, much easier editing system is required. As well, REL Consumption System to process and analyze REL documents, the RDD interoperability system to interoperate REL and RDD are needed. In this paper, REL Editing System and REL Consumption System, RDD Web Services System were designed and implemented, REL Editing System to make REL document, REL Consumption System to process and analyze edited documents, RDD Web Services System to process rights inquiry base on the Web Services.

Plain old Web Services came true a services integration with use the XML that will be able to define a platform-independent document format in basic document format. Hut, the XML document decreases the efficiency of the whole application program with connects frequently in relatively slow communication media like network environment, embedded system or use the resource limited small-sized instrument like mobile. In this paper, we implemented the algorism of Fast Infoset, which can convert XML into Fast XML using the Fast Inoset method and PER encoding rules in ASN.1 and constructs Test Bed. Also, it is compared with the existing pure XML message method in difference of process performance after encoding SOAP messages of XML basis when constructing web service.

With advent of IPTV services and availability of various web contents, users can enjoy various contents via internet. In order to effectively provide a large amount of web contents to users, personalized IPTV services are required to the user's sides. In this paper, we extend the current ATOM schema for personalized IPTV services and propose a IPTV service framework based on IPTV personalization.

Web services provide an effective means to carry out coordinated transactions between multiple, independent business parties. While there are several specific protocols currently being discussed to address the coordination of web services-enabled business transactions, we consider the tentative hold protocol (THP) that allows the placement of tentative holds on business resources prior to actual transactions in order to provide increased flexibility in coordination. In this paper, we present a formal coordination framework for applying THP in conjunction with 2PC to the problem in which service providers independently manage resources and clients seek to acquire the resources from multiple providers as a single atomic transaction. The proposed framework facilitates the performance optimization of THP through effective parameterization with the notion of overhold size and hold duration. The simulation results show that the proposed adaptive approach yields a significant improvement over other non-adaptive policies.

In this paper, we introduce the sharable and reusable learning objects which are suitable for XML Web services in e-learning systems. These objects are extracted from the principles of pedagogical paradigms for reusable learning units. We call them LIO (Learning Item Object) objects. Existing models, such as Web-hosted and ASP-oriented service model, are difficult to cooperate and integrate among the different kinds of e-learning systems. So we developed the LIO objects that are suitable for XML Web services. The reusable units that are extracted from pedagogical paradigms are tutorial item, resource, case example, simulation, problems, test, discovery and discussion. And these units correspond to the LIO objects in our learning object model. As a result, the proposed model is that learner and instruction designer should increase the power of understanding about learning contents that are based on pedagogical paradigms. By using XML Web services, this guarantees the integration and interoperation of the different kinds of e-learning systems in distributed environments and so educational organizations can expect the cost reduction in constructing e-learning systems.

In this paper, an implementation method of augmented reality (AR) technology using Web 3.0 information services in the field of disaster response is proposed. The structure and characteristics of semantic web-based Web 3.0 are realized and a AR based mobile visual search (MVS) applied in the disaster sites is described. Based on Web 3.0 and AR MVS, a semantic web ontology oriented configuration scheme for disaster-related information and the communication scheme of information provided by AR technology are proposed. For the purpose of providing disaster-related and customized information to the disaster response site quickly and accurately, a method of leveraging Web 3.0 information services in AR technology is presented.

Recently, online real-time web accessible mobile devices such as smartphones, tablet PCs and application services have been developing rapidly. Hospitals also need to adopt an efficient information system that can provide decent medical services under mobile computing environments to complete future medical services. This study proposes a system in which a doctor can examine a patient and make out a prescription in a ward on a real-time based on the current Order Communication Systems (OCSs) through mobile interfaces. The proposed system implements mobile web pages using HTML5, instead of a mobile app. Web processing speed can be enhanced using the web socket and web storage functions of HTML5.

As the state of the art for handling multimedia on the internet is developed a new system called WebCAM which services video and image came out. However, WebMIC site for audio services are still rare. In this work, we developed a WebMIC system which enables anyone to listen audio in real-time through the internet. WebMIC system is implemented by connecting a server with a microphone and the recorded audio files are stored in a Database system. Because the microphones can be distributed sporadically, the developed system can be utilized for managing and advertizing a location. It also can be used to reduce the cost for the existing management system which is almost met by personnel expenses. Anyone who can connect to the internet can get this WebMIC service, so this system can produce a good effect if used in advertising any tourist resort.
