This paper describes an architecture information management system using XML. The purpose of the system is to manage the information stored in standard format, XML, that has many valuable properties. The proposed architecture information consists of project information, drawing information, and material information. Each information is expressed using XML and for each information, XML schema is presented in this paper. In this system, detail information of materials that exists on the supplier's homepage can be displayed when the user of the system wants to check the detail information. Also, drawings stored in STEP data can be browsed in this system. The reports of each information are prepared using XSL. The proposed system shows that XML can be used for a format to store architecture information and various functions can be implemented based on XML related standards.

Despite the large and ongoing investments in information systems and technologies, many organizations still suffer from the lack of integration and interoperability of multiple information systems, In order to deal with these enduring problems, a number of government organizations and corporate firms in the United States have developed and maintained IT architectures through enterprise architecture planning. An IT architecture is a decision-making framework for IT planners and developers, establishing guidelines for the individual IT resource owners and users. It provides guidance to those involved in building and maintaining IT systems and infrastructure. Enterprise architecture planning represents a new paradigm of information systems planning in that it addresses the long-term view of the enterprise organization from top-level principles to detailed technology architectures. This paper explores a couple of cases in the successful implementation of IT architectures in both public and private sectors, and proposes a step-by-step methodology for building an effective IT architecture.

It was on the rise importantly to provide the efficient management process of the organization for dealing with the change about information and business management quickly and consistently. It was suggested with the architectural model on information technology to provide it in theoretically. The Federal Government and budget organization of the USA used it on actual business and the terms of EA (Enterprise Architecture) and are raising the efficiency of management. NCA (National Computerization Agency) of Korea published the book - "The Research about establishing ITA (Information Technology Architecture) and appling the standards". After being applied the model on MOGAHA (Ministry of Government Administration and Home Affairs) and MIC(Minisstry of Information and Communication), the concrete case was made. MOMAF (Ministry of Maritime Affairs and Fisheries) drove the leading model. The report ascertained the basic contents of ITA and researched the case of USA, MOGAHA, MIC, and tried to analyze the contents of appling maritime and fisheries area. The report contained the definition of purpose through analyzing environment and establishing the vision and the principles based on them. The report also contained the contents of architecture based on the standard of NCA - "The Government Standard Meta Model version 2.0" - and researched the MOMAF's Reference model using Government Reference model. The report established the investment architecture and the process of information technology asset management. It ascertained the characteristic of maritime & fisheries area and the subject of developing the MOMAF's ITA sustainably.

Traditional information systems in the Ministry of National Defense(MND) are insufficient about interoperability between all kinds of them. Also there is no the applicable architecture framework to develop information systems. The Architecture Framework(AF) is to provide guidance for describing architectures for both warfighting operations and business operations and processes in the MND. Therefore, in this paper we propose the MND AF to develop and manage information systems in the MND.

본 연구는 정보보호 아키텍처 구성과 보안활동이 정보자산보호 및 조직성과에 미치는 영향력을 밝히는데 목적을 갖고 정부, 공공기관, 민간 기업 종사자 300명을 대상으로 설문조사 하였다. 연구결과 분류식별과 위험분석 관리요인이 내부정보 유출방지를 위한 정보보호 아키텍처 구성 및 보안활동에 유용성을 갖는 것으로 나타났다. 그리고 정보기술 아키텍처와 구성원의 인식과 교육요인은 기각됨으로써 제한적인 정보보호 아키텍처 구성 및 보안활동이 요구됨을 시사해 주었다. 독립변인으로서의 아키텍처와 구성원에 대한 재인식을 위한 교육은 그 만큼 중요함을 인식시켜 주고, 일반화된 프로세스로 정보보호 통제나 관리 활동에 크게 기여하지 못하고 다만 위험분류 식별관리와 위험분석 관리의 일반화를 통한 엄격한 보안활동이 유의적인 조직성과에 미치는 영향이 큼을 시사해 준 것이라 할 수 있다.

The study is about a finite field multiplying unit, which performs a calculation t-times as fast as the Mastrovito's multiplier architecture, suggesting and using the 2-times faster multiplier architecture. Former studies on finite field multiplication architecture includes the serial multiplication architecture, the array multiplication architecture, and the hybrid finite field multiplication architecture. Mastrovito's serial multiplication architecture has been regarded as the basic architecture for the finite field multiplication, and in order to exploit parallelism, as much resources were expensed to get as much speed in the finite field array multipliers. The array multiplication architecture has weakness in terms of area/performance ratio. In 1999, Parr has proposed the hybrid multipcliation architecture adopting benefits from both architectures. In the hybrid multiplication architecture, the main hardware frame is based on the Mastrovito's serial multiplication architecture with smaller 2-dimensional array multipliers as processing elements, so that its calculation speed is fairly fast costing intermediate resources. However, as the order of the finite field, complex integers instead of prime integers should be used, which means it cannot be used in the high-security applications. In this paper, we propose a different approach to devise a finite field multiplication architecture using Mastrovito's concepts.

The reconfigurable architecture is increasingly important for design of multi-mode communication systems and computation-intensive DSP systems. The proposed coarse-grain architecture is based on a reconfigurable processing element consisting of a MAC unit, a register file, a context data register, and PE interconnect control blocks. The main feature of the Proposed architecture is the loop context which enables faster configuration. Also, we propose another area-efficient reconfigurable architecture with improved reconfigurability. The SystemC modeling results show that the proposed architecture can reduce 9 clock cycles of 2D DCT compared to existing architectures.

In this paper we designed a service composition architecture which enables the functional extension of existing service or the creation of new service by combining more than one service. The designed composition architecture is based on the service architecture of the TINA-C. It is designed by extending TINA information model and computational model. Composition related object, relations and interface between objects are defined in the information model and the computational model. And we tested the designed architecture by implementing two multimedia service and composition the services.

This paper presents a reconfigurable digital signal processing(rDSP) architecture that is effective for implementing adaptive digital signal processing in the applications of smart health care system. This rDSP architecture employs an evolution capability of FIR filters using genetic algorithm. Parallel genetic algorithm based rDSP architecture evolves FIR filters to explore optimal configuration of filter combination, associated parameters, and structure of feature space adaptively to noisy environments for an adaptive signal processing. The proposed DSP architecture is implemented using Xilinx Virtex4 FPGA device and SMIC 0.18um CMOS Technology.
