A mobile computing environment has many difference in character from conventional communication over wired network. These include very presents distributed design system based the mobile agent for mobile computing environment. To integrate design resource, we presented ISA(Integration Service Agent, which allows a designer to build integrated application using distributed resources, and to collaborative by exchanging service. Also we propose ICM(XML based Intelligent Connection Manger) using mobile agent. And suggested new intelligent data and process transfer architecture using ICM to implement an agent based design system in mobile environment.

This study was concerned about mobile web-service of a VMI in the SCM system. The VMI would be a main module part of the SCM and regarded as very important thing on supply chain. Therefore, it was essential to react in real time of materials production and situation of used auto-part in procurement company. We could find an affordable method to realize the VMI in a web service. The web service has made inter relevant enterprise easy to collaborate because of supporting most operating system and frame-work. Moreover, the use of a mobile tools was guaranteed a product recording and requirement of materials to real time in a rapid changing of production environments. The result of this research was very useful to apply the VMI system in medium and small sized auto parts company. This web service package has programmed the Visual Studio Dot Net 2003 and the MS SQL 2000 as database.

Recently, many WMS(Web Mapping Services) and POI(Point of Interest) service on to be in service on the Internet using Web CIS(Geographic Information System) as information Technology and computer HW are evolved faster in its speed, network bandwidth and features. The Web GIS is, however, limited and constrained on the specification of its system configuration, the service class provided and the presentation methodology of a map. As the mobile Internet becomes popular in mobile service, Web GIS service on mobile environment is strongly required and to be provided by LBS(Location Based Service) on a mobile client such as PDA with location information of the user. In this paper, we made an effort to design and implement a GIS computing environment by thin client for mobile web mapping service. For implementing the thin client GIS computing environment, we were using NGII's(National Geographic Information Institute's) DXF map, representing the map by SVG(Scalable Vector Graphics) recommended by OGC(OpenGis Consortium), and adapting standard XML web service to provide the thin client GIS service on PDA by applying the location information of the user in realtime with GPS on mobile environment.

Recently mobile SFA(Sales Force Automation) system makes rapidly progress specially in industries like insurance, manufacture, and distribution. However, there are some problems that information about products and trades is not promptly shared among sales agents or customers, since the current mobile SFA system has simply extended the existing systems for sales management. In order to improve these weaknesses, we introduce LBS(Location Based Service) and mobile P2P(Peer to Peer) service into the existing systems, then design and implement the enhanced system (or mobile SFA using them. Through this improvement, our system makes it possible for customers or sales agents to quickly share various information and increases the efficiency of sales activity by facilitating the competition and cooperation among sales agents and reducing time-cost.

Perhaps, one of the typical emerging markets drawing tremendous attention from not only business professionals but also policy-makers would be the mobile Internet services. In recent years many research institutes reported their predictions on the growth of the mobile Internet services market, announcing that the market would show explosive growth and replace the wired Internet service market rapidly. Unfortunately, however, the reality we are facing at present is quite different from their expectations. The realized share of the mobile services in Korea last year has turned out remaining only about one percent of the total network service revenue. What are the reasons for the gap between the prospects and the reality? Starting from this question, this paper attempts to explore the generic pitfalls of the traditional number-crunching methods adopted thus far for the forecast of newly emerging market trends, and present an alternative by introducing systems thinking to the mobile Internet service market as an example, followed by its rationale as a new tool for forecasting and some reasoning about why traditional methods are no longer appropriate.

On the limited urban area meteorological data are hard to be collected because of the cost problem. The facilities collecting the data require high installment cost. Recently, the sensor network technique comes to the fore as a solution. Furthermore a mobile phone also becomes to be recognized as a sensor. This paper studies an application to service the meteorological map using mobile phone sensor. A design results for system implementation are introduced in this paper.

The development of various contents has been accelerated with the explosive increase of the number of internet users, the rapid expansion of wireless internet service and the pervasion of mobile terminal. Mobile service is able to offer the elastic service to anyone regardless of the place and the time. With this characteristics, this service could be extended even to the pace which the access was limited with the existing line service. The purpose of this study is to propose a system which is able to make a remote control of computer by means of mobile as an example of the production of contents for such mobile service. With this system it could be identified what kind of job a user of PC is making by mobile phone regardless of the time and place. The functions such as termination reboot, messenger, macro execution, and timer are included. The greatest advantage of the system proposed in this paper is to protect the youth, who are making an access recklessly to the harmful site, by use of mobile at my time and any place.

The utilization of the Mobile Government system is having more than a few challenges including complexity of different mobile technologies, determining interoperability among existing systems and infrastructures, and establishing services with secured networks. To get over those challenges, integrated standard, innovative and comprehensive system architecture is required by the M-Government. Hence this study proposed reference EA framework for M-Government system in order to avoid unnecessary duplication of infrastructure deployment and integrate services among different government instructions. The study based on literature review, and current infrastructure and mobile network situation for delivering Government services of Mongolia. The study recommends innovative m-Government system framework used EA, and scope covered mobile service delivery area centered on G4C and C2G perspectives. The Federal Enterprise Architecture Framework has used in this research, and the proposed system service architecture defines the interoperable standards, infrastructure components, applications, and technologies for government institutions in Mongolia to aid interactions necessity among them to provide m-Service.

In recent years, one of the main trends of GIS is to construct and provide realistic and human-perceptible information of spatial object using video data. The rapid progress of wireless mobile technology makes the multimedia source using video data possible on mobile environment. Instead of traditional map-based service, video-based location services, that provide video data as location context, would be of interest in connection with various mobile applications requiring location service, such as telematics, LBS, etc. In this paper, we present the location service system using geo-referenced video on wireless mobile environment.

The mobile SNS is a promising e-service platform of the future. However, measuring its service quality is a challenge. An appropriate model for measuring service quality is required. This paper proposes e-service quality models for analyzing mobile SNS platform quality, based on previous service quality researches. An empirical study is performed on the proposed models. The results show that constructs of existing e-service models such as responsiveness and assurance do not fit the mobile SNS platform, and that loyalty and value are better measures for mobile service quality.
