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.

This paper describes an operational concept of ships with CEC system. An operational architecture is derived using systems engineering approach. From consideration of operational environments and stakeholders, the operational concept scenarios are established and its requirements are derived. The operational requirements based operational architecture is presented using a computer aided systems engineering tool.

Under the relevant regulations, it is required to develop a system architecture for the research and development of the information and communication infra system ; however, the national defense architecture development guides and MND-AF, which provide the instructions on the development and utilization of a system architecture, are still limited to the ITA level and merely providing the guidelines for developing the information system centric architecture. Thus, it is evident that we need a suitable architecture development methodology that corresponds to the growing needs for the communication infra system architecture, as well as the general weapon system architecture. Improving a meta-model is the core of improving a architecture framework. It determines a contents of a architecture and it influences a efficiency and a effectiveness of a architecture. The meta-model of the architecture framework must reflect concerns of various stakeholders and provide a traceability among them. Also, it should be easy to develop and use the architecture by securing the feasibility of the logical relationships and eliminating the duplication of the data inside the architecture. It is implemented through the development of the data-centric architecture and achieved through the "Fit-for-purpose" concept.

The purpose of this study is to establish the relationship between Durand's architectural theory which provided reasonable architectural logic in the early 19th century, and architectural logic of the Modern Movement of Architecture led by avant-garde architects in the 1920's. The system of thought in architecture proposed by Durand which clarified a architectural design method(composition) is very similar to the one of the International Style(Book), which summarizes commonalities in the flow of modern architecture. This approach has something in common from the perspective of the systems of thought, despite differences in external forms and time gaps. Therefore, this study intends to examine the systems of thought in three ways. It is to examine how the two systems of thought define architecture, what is the logic of building production, and finally the value of architecture (including aesthetic values) while eliminating classical aesthetics.

The advance of computer, network, and Internet technology enables the control systems to process the massive data in the distributed computing environments. To implement and maintain the software in distributed environment, the component-based methodology is widely used. This paper proposes the middleware architecture for the distributed computer control system. With the proposed middleware services, it is relatively easy to maintain compatibility between products and to implement a portable control application. To achieve the compatibility between heterogeneous systems, the proposed architecture provides the communication protocols based on the XML with lightweight event-based service.

The operational concept of control systems on surface combatants has been changed from individual control for each system to integrated control for all systems due to computing technology development and crew reduction policy of navy. The purpose of this study is to identify current status of control technology, to analyze user requirement and to develop an architecture to support the conceptual change of ship control. An architecture, which integrates several control and monitoring systems on naval surface combatant, is proposed. The proposed architecture is focused on sharing network and computing resources related to user command, and reducing systems complexity. The architecture can be adopted to next surface combatants in Korean navy.

At present, the EDI systems are indispensable software in port logistics industry. Currently, a monopolistic VAN/EDI service provider operates the EDI services. The current EDI client software has the 2-tier fat client/server architecture. However, the current EDI software is lack of Web interface and causes lots of cost for maintenance. Therefore, a variety of implementation architecture has been being tried by using script, XML and distributed object-oriented technology. Web/EDI and XML/EDI are the new EDI systems, However, the EDI systems have some limitations such as speed. This study intends to compare the variety implementation architecture for the EDI systems in the users' perspective and explore the strong and weak points of each architecture. We compared the EDI systems based on our experience of more than 2-years of implementation project for the EDI systems of port logistics. We categorized the EDI systems as client application EDI, Web EDI using script, XML/EDI, and 3-tier distributed object-oriented EDI system. We compared them with criteria such as speed, program maintenance, easiness of implementation and usage, security, and load balancing and fail-over. Finally we discuss the direction of optimal EDI system architecture for the future.

This paper describes the establishment of defense systems test works architecture model for the efficient operation of an expanded test organization and the provision of standardized test services after the integration of proving grounds in ADD. The system engineering vee model is applied to the defense system test works to define the project management model and the unit-test management model. In order to establish the defense systems test works architecture model, the process flow of test works, artifacts by life cycle, and interrelations between regulations and test works are explained, and Integrated Test Information System for implementation of architecture model is discussed. Through the defense systems test works architecture model presented in this study, it will contribute to quickly responding to the test requirements of complex and diverse defense systems, efficiently managing projects, and providing standardized test services.
