Web2.0 refers to a new service models based by a community oriented philosophy. This creates new opportunities for technology providers and service. The agricultural technology information service in the base of open source technology provide opportunities for increased distribution and visibility to farmer and general user. We would like to find out vest service models and platform that will find new ways of agriculture technology information service. This study suggests that these new agriculture information service strategy in new paradigm of web 2.0. should be revised and adapted to Open API and new applied strategy in agriculture should be developed considering the impact of web 2.0.

This growth if WWW(World Wide Web) with the spread of ADSL provides us with a variety of service that are the extensions of opportunities to get information. a various education methods by remote courses and electronic commerce. Remote Monitoring Server(RMS) that uses internet and WWW is constructed for chip mounter. Hardware base consists of RMS, chip mounter and C/S server. In this paper, we realize the remote management system with monitoring and diagnosis function to efficiently operate chip mounter the one of PCB assembly equipment. The remote management system for chip mounter consists of RMS(Remote Monitoring Server) and C/S server. RMS manages real-time information from chip mounter through TCP/IP. RMS that utilizes real-time information informs user of the actual output the operation status of chip mounter, user of the actual output, the operation status of chip mounter, the trouble code and the trouble description.

Recently, as the Geospatial Web is combined with the Semantic Web in order to keep pace with the recent trends of information technology emphasizing interoperability, intelligence and individualization, the Geo Semantic Web was proposed, which is an intelligent geographical information Web service technology that can provide users with suitable information by connecting and integrating various types of spatial information and extensive aspatial information on the Web efficiently. For the Geo Semantic Web service, we need to develop Geo Ontology processing technologies that enable computers to process knowledge and information scattered around in the Web environment automatically. However, standards for Geo Ontology processing technologies have nod been established yet, and standardization organizations and various groups and agencies are conducting relevant studies. This paper analyzed various base theories and technologies related to Geo Ontology and developed a Geo Semantic Web system. The Geo Semantic Web system comprises Query Processing Manager that analyzes and processes Geo Semantic queries and manages sessions, Ontology Manager that generates and queries Geo Ontology and extracts spatial/aspatial data, and Clients. Finally, this paper proved the utility of the Geo Semantic Web system by applying it to a hypothetical scenario where Geo Semantic queries are required.

Massive amount ofinformation is provided for the internet users. Therfore, the users are exposed even to the useless information. In this paper, a Intelligent Web-Agent system is present as a solution for this kind if users inconvinience. This Intelligent Web-Agent system i devised users to search by the keyword about which they get information and commend the sites which have more intensive relation with the examine keyword, judge by the users and the case-base constructed by the Intelligent Web-Agent system itself previously, so the users can access the essential web sites in short time. Intelligent Web-Agent system is compose of a interface-system and a learning system. According to the experiment, using the Intelligent Web-Agent System quicker than the case when not using the Intelligent Web-Agent System.

This paper discusses the development of an educational web-based power flow program for undergraduate students. The interaction between lectures and users can be much enhanced via the web-based programs which result in the student's learning effectiveness on the power flow problem. However the difficulties for developing web-based application programs are that there can be the numerous unspecified users to access the application programs. To overcome the aforementioned multi-users problem and to develope the educational web-based power flow program, we have revised the system architecture, the modeling of application programs, and database which efficiently and effectively manages the complex data sets related to the power flow analysis program. The developed application program is composed of the physical three tiers where the middle tier is logically divided into two kinds of application programs. The divided application programs are interconnected by using the Web-service based on XML (Extended Markup Technology) and HTTP (Hyper Text Transfer Protocol) which make it possible the distributed computing technology Also, this paper describes the method of database modeling to handle effectively when the numerous users change the parameters of the power system to compare the results of the base case.

As composite materials are gaining wide acceptance in aircraft structure, repair of damaged composite is becoming an important issue. The issues in composite repair include high cost, material interchangeability, water ingression, and structural integrity. To address these problems, researchers have studied on the composite repair in various aspects. In this paper, an Internet-based advisory service (called Repair Advisory Service, RAS) for composite repair is proposed to increase efficiency for repair process. In the RAS system the web browser is used as its user interface, which provides easy access to the service. The RAS server provides web-based tools for failure prediction, Structural Repair Manual (SRM), automated prepreg cutting process, material properties, inventory and knowledge base. The computer codes implemented for repair design estimate the tensile failure and shear failure of repaired structures. The prediction of failure is based on the maximum strain criterion for tensile failure while elastic-perfect plastic shear failure model is applied for interfacial failure. The OEM's SRM is provided in the PDF format for viewing and searching by web browsers instead of looking up paper version SRM. The knowledge base in this site offers a room to share and distribute ideas, memos, publications, or suggestions from the repair engineers. The fabrication tool of RAS reads repair geometry from engineers then generates a CNC toolpath to cut prepreg patches. The RAS service is open to public and available at http://nano.gsnu.ac.kr/. Broad feedback from field technicians and engineers is welcome to improve the usefulness of RAS.

In this paper, we present a spatial knowledge extractor implemented in Hadoop MapReduce parallel, distributed computing environment. From a large spatial dataset, this knowledge extractor automatically derives a qualitative spatial knowledge base, which consists of both topological and directional relations on pairs of two spatial objects. By using R-tree index and range queries over a distributed spatial data file on HDFS, the MapReduce-enabled spatial knowledge extractor, MRSPAKE, can produce a web-scale spatial knowledge base in highly efficient way. In experiments with the well-known open spatial dataset, Open Street Map (OSM), the proposed web-scale spatial knowledge extractor, MRSPAKE, showed high performance and scalability.

This study was conducted to develop the Apartment Information System. This integrated information system is designed to provide a large number of users with the convenient, economical, and safe life in the apartment complex. The characteristics of this system are as follows; 1) The system was developed by CAD technology using 2D and 3D methods with Web base. 2) This system has 2-Tire structures which are able to embody the geographic information on the Web base without special Spatial Engine. 3) Since the spatial data applied to this system is a vector file format, the speed of electrical transmission is fast and it makes possible to search spatially for the client method. The results of this study may contribute to make use of the information system for apartment complex as follows; 1) This system can be used together by the communities of apartment residence, maintenance company and construction company. 2) Also this system can help residence to communicate sharing information and can support the apartment management with open information and clarity. Expecially, the practical data gathering was made for this study only.
