IETF has proposed CNRP that is a protocol exchanging CNRP objects between server and client for resolving a common name to URIs of the desired Internet resouces. CNRP enables users to access various services via the integrated interface, to easily get the desired resources, and to reuse the results not as the data but as the information. Whereby these advantages, CNRP will be generally used for the integration of the various Internet services or the applications where the resolution of common name is needed. But, CNRP specification doesn't describes the practical implementation method for server and client. Though a few prototype systems are developed in some researches using CNRP, they are not enough to be generally used for the various Internet applications because they doesn't include all objects specified in CNRP specification or they construct systems with one server. So, this Paper proposes the practical implementation method for CNRP server/client through analyzing and solving the problems occurred when implementing them, and implements all objects specified in CNRP specification. This paper also verifies the feasibility of the proposed method by developing the prototype system of the company name resolution service using the CNRP server/client implemented in this study. The CNRP server/client implemented in this paper are used to develop various CNRP application systems.

A widget is a small application running by the users' favorite services, so they are provided with web contents without explicitly visiting the web site. Although widgets can be easily implemented with Open APIs, only a few web sites provide them because of refactoring the structures of web resource to supply Open APIs to the widget developers. This paper presents an Open API Proxy Server System for widget services. The system consists of two components: an Open API Source Code Generator and an Open API Proxy Server. The Open API Source Code Generator provides a Graphical User Interface (GUI) for users to generate the Open APIs of user's choice and sends the Open API source code generation request to the Open API Proxy Server. The Open API Proxy Server using the HTML Table Processing Library receives the HTML web page from web site and extracts useful information from the target HTML table. The proxy server converts the extracted data into the corresponding XML document which becomes available through the Open API. We verify the operation of the proposed system through experiments with the HTML tables in the example web sites.

To guarantee the effectiveness of the HACCP(Hazard analysis and critical control points) system, it is necessary to develop of an ontology-based information system that can automatically manage the large amount of HACCP records or information derived from the HACCP operation results. In this paper, we construct a food information ontology which represents the relationships between ingredients, recipe, and features of food categories. Moreover, we develop HACCP automation application adopt the ontology to verify the semantic quality of the designed ontology model by performing HACCP processes such as HACCP diet classification. We expect to contribute to develop a food hygiene information and improve the accuracy of the HACCP data through the semantic system.

The purpose of the study was to construct a system based on the semantic web environment's ontology by utilizing the ontology schema derived from the facet-type Art and Architecture Thesaurus(AAT). The aforementioned ontology schema is based on the Web Ontology Language(OWL), which is being widely considered the standard ontology language for the W3C-centered semantic web environment. Also, the concepts were limited to terms within AAT'S Furniture Facet, and the system was tested using the Chair concept, which is a lower-level facet that has a diverse conceptual relationship and broad vocabulary base. The ontology system is capable of searching for concepts, while controlling the search results by always providing a 'Preferred term' for synonymous terms. In addition, the system provides the user with first, a relationship between the terms centered around the inquiry, and second, related terms along with their classification properties. Also, the system is presented as and application example of the ontology system that constructs a information system that intakes an Instance value and reproduces it into a RDF file. During this process, utilization of multiple ontologies was introduced, and the stored Instance value's meta-data elements were used.

IMO adopt the revision of SOLAS convention on requirement systems for ECDIS and considered an ECDIS as the major system for E-Navigation strategy on marine transportation safety and environment protection. ENC(Electronic Navigational Chart) as the base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. Because ENCs are not easy to utilize for being encoded according to ISO/IEC 8211 file format, used for navigational purpose mainly, it's required to utilize in parts of Marine GIS and various marine application. In this paper, we developed KML conversion technology for ENC application. In details, we analyzed data model and encoding method of ENC, schema structure and data file of KML. Based on this results, we developed the program of KML conversion of ENCs.

Quality of the web service is one of the most important elements as various web services provide diverse functionality, and therefore, it is more and more difficult to satisfy customer's needs. Since the existing UDDI registry provides the basic information such as name and URL of a web service, users are having hard times to choose and customize their web service. In this paper, we propose an extended UDDI architecture for providing quality data of a web service. And in this architecture, we used an automated collection technique of data for testing web service which provides quality information to the users, including response time, throughput, availability, reliability and accessibility. With this new architecture, users and web developers can benefit from web services that customize information for the users and this ensures reliability of web-based applications.

Ajax interaction model changes the posture of web application to become a stateful over HTTP. Ajax applications are long-lived inthe browser. XMLHTTPRequest (XHR) is used to facilitate the data exchange. Using HTTPS over this interaction is not viable because of the frequency of data exchange. Moreover, switching of protocols form HTTP to HTTPS for sensitive information is prohibited because of server-of-origin policy. The longevity, constraint, and asynchronous features of Ajax application need to hove a different authentication and session fondling mechanism that invoke re-authentication. This paper presents an authentication and session management scheme using Ajax. The scheme is design lo invoke periodic and event based re-authentication in the background using digest authentication with auto-generated password similar to OTP (One Time Password). The authentication and session management are wrapped into a framework called AWASec (Ajax Web Application Security) for coupling to avoid broken authentication and session management.
