Design and implementation of remote procedure cail (RPC) resource service system based on the XML considering the request delegation between the servers are described for the resource application and efficient processing of distributed environment. For this purpose, the request information about several server, which would be used by client, is encoded into XML document based on XML-DOM and transferred to server. Server classifies the client requests using objects which can deal with the XMLL-DOM. For the request delegation between the servers, server saves the request result of client in XMLL-DOM structure without replying it immediately, and makes the client request delegated to another server in XML-DOM's request information. In addition, the resource repository are managed for resource transparency of distributed environment. As a result, resource application and processing efficiency are improved by reduction of response time caused by integration of RPC and XML-RPC services and request delegation between the servers. Extension of asynchronous and average blocking time of client were reduced and information of resource which can be used by client was offered.

Recently as the user request on NoD (News-on-Demand) is largely increasing, there are a lot of researches to fulfill it. However, because of short life-cycle of new video data and periodical change of video data depending on anchor, it is difficult to apply the conventional video storage techniques to NOD applications directly. For this, we design and implement low-level storage manager for efficient storage and retrieval of multimedia data in NOD Services. Our low-level storage manager not only efficiently sotres video stream dat of new video itself, but also handles its index information. It provides an inverted file method for efficient text-based retrieval and an X-tree index structure for high-dimensional feature vectors. In addition, our low-level storage manager provides some application program interfaces (APIs) for storing video objects itself and index information extracted from hierarchial new video and some APIs for retrieving video objects easily by using cursors. Finally, we implement our low-level storage manager based on SHORE (Scalable Heterogeneous Object REpository) storage system by sunig a standard C++ language under UNIX operating system.

It is not easy to achieve the essential goal of knowledge management, which is to strengthen individual competence and organizational competitiveness, only by collecting distributed knowledge in the centralized knowledge repository conducted so far. In order to establish a sustainable knowledge ecosystem, we must expand knowledge production through exchange and cooperation, not independent knowledge production. Through this, producing meaningful and high-value knowledge resources becomes possible. Therefore, this study aims to design an integrated service platform that stores science and technology knowledge resources and reproduces and evolves knowledge through opening, sharing, and utilization. In order to evaluate its excellence, Five experts evaluated the designed platform on detailed items classified into planning adequacy, platform effectiveness, platform efficiency, and roadmap adequacy. The evaluation score averaged 95.56 points for the above four evaluation items.

Clustering is representative method of components classification. But, previous clustering method that use cohesion and coupling can not be effective, because design pattern has consisted by relation between classes. In this paper, we classified design patterns with special quality of pattern structure. Classification by clustering had expressed higher correctness degree than classification by facet. Therefore, can do that it is effective that classify design patterns using clustering algorithms that is automatic classification method. When we are searching design patterns, classification of design patterns can compare and analyze similar patterns because similar patterns is saved to same category. Also we can manage repository efficiently because of using and storing link information of patterns.

유비쿼터스 환경에서 많은 정보는 공유되고 누구나 쉽게 접근하여 정보를 교환할 수 있어야한다. 이를 위하여 Jini 서비스 중 하나인 JavaSpace는 Java 객체를 저장하고 저장된 객체에 접근할 수 있는 공간을 제공한다. JavaSpace 서비스는 객체를 공유하는 방법으로 매우 유용하게 사용되고 있지만, 보안성이 취약하여 객체정보에 대한 접근 보안이 요구되는 분산시스템의 개발에는 적합하지 않다. 본 논문에서는 JavaSpace의 취약한 보안성을 강화시켜 안전한 JavaSpace 서비스를 제공하는 SecureJS 시스템을 개발하여 보안 정책과 그 구현에 대하여 설명한다.

Dialogue speech corpora that contain sufficient dialogue speech features are needed for performance assessment of a spoken language dialogue system. And labeling information of dialogue speech corpora plays an important role for improvement of recognition rate in acoustic and language models. In this paper, we examine the methods by which labeling information of dialogue speech corpora can be structured. More specifically, we examined how to represent features of dialogue speech in a structured document based XML and how to design the repository system of the information.

This paper presents the results of a structural analysis to determine design variables such as the inner basket array type, and thicknesses of the outer shell and the lid and bottom of a spent nuclear fuel disposal canister. The canister construction type introduced here is a solid structure with a cast iron insert and a corrosion resistant overpack, which is designed for the spent nuclear fuel disposal in a deep repository in the crystalline bedrock, entailing an evenly distributed load of hydrostatic pressure from the groundwater and large swelling pressure from the bentonite buffer. Hence, the canister must be designed to withstand these large pressure loads. Many design variables may affect the structural strength of the canister. In this study, among those variables, the array type of inner baskets and thicknesses of outer shell and lid and bottom are attempted to be determined through a linear static structural analysis. Canister types studied here are one for the pressurized water reactor (PWR) fuel and another for the Canadian deuterium and uranium reactor (CANDU) fuel.

Hybrid simulation is increasingly being recognized as a powerful technique for laboratory testing. It offers the opportunity for global system evaluation of civil infrastructure systems subject to extreme dynamic loading, often with a significant reduction in time and cost. In this approach, a reference structure/system is partitioned into two or more substructures. The portion of the structural system designated as 'physical' or 'experimental' is tested in the laboratory, while other portions are replaced with a computational model. Many researchers have quite effectively used hybrid simulation (HS) and real-time hybrid simulation (RTHS) methods for examination and verification of existing and new design concepts and proposed structural systems or devices. This paper provides a detailed perspective of the enabling role that HS and RTHS methods have played in advancing the practice of earthquake engineering. Herein, our focus is on investigations related to earthquake engineering, those with CURATED data available in their entirety in the NEES Data Repository.

In this paper, we design and implement a XML management system based on OODBMS that supports structured information retrieval of XML documents. We also propose an object oriented modeling to store and fetch XML documents, to manage image data, and to support versioning for the XML document management system(XMS). The XMS consists of a repository manager that maintains the interfaces for external application programs, a XML instance storage manager that stores XML documents in the database, a XML instance manager that fetches XML documents stored in the database, a XML index manager that creates index for the structure information and the contents of documents, and a query processor that processes various queries.
