Modeling and simulation techniques construct experimental environment considering battlefields and are able to analyze performance of components of weapon system that closely resemble reality. However, developed model has low scalability and not cared reusability because it has been used only in a limited range of domain. In this paper, we develop a verification tool to verify reusability of developed component for dynamic reconfiguration and to judge scalability of it and a management tool to control data of it effectively. In addition, dynamic reconfiguration architecture of guided weapon systems designed in the previous study has been applied to SAM(Surface to Air Missile) System Simulator, and we study effectiveness of the developed component. Thus the user can configure various guided weapon systems through simulation application of dynamic reconfiguration architecture of component.

Many technical and nontechnical issues hinder enterprise wide workflow management. The most significant technical issue is the inability to deal with the heterogeneity among users, workflow types, and WFMSs. Not all users demand the same workflow functionality, so user interfaces of different levels of sophistication are required. Because workflow types cannot always be fully predefined, they often need to be adjusted or extended during execution. Unlike relational database management systems, however, each WFMS often has differing workflow metamodels. This leads to incompatibility between WFMSs, making integration into an environment comprising many heterogeneous WFMSs a troublesome and sometimes impossible task. Current Workflow system consists mainly of Database system. It contains some problems like that the integration relationship among system processes cant be expressed properly. This research has been focused on two phases that should be considered in the Workflow system. First of all, the first phase is the analysis phase; one of its role is to figure out independent execution task unit(Workflow component). The second phase is design phase that provides with the framework to execute these task units actively. The Workflow component extraction method in the analysis phase uses a analysis method called C-C Net and, in the design phase, the architecture that makes the these Workflow component executed actively is provided. Through this research, each process is divided into a task unit and more effective Workflow system could be formed by executing these units actively. Current system layer calls task units, on the other hand, the Workflow system this research implemented provides with the architecture that places a layer between them that controls task units actively.

Recently, a lot of researches about mobile vision using Personal Digital Assistant(PDA) has been attempted. Many CPUs for PDA are integer CPUs, which have no floating-computation component. It results in slow computation of the algorithms peformed by vision system or image processing, which have much floating-computation. In this paper, in order to resolve this weakness, we propose the Client(PDA)/server(PC) architecture which is connected to each other with a wireless LAN, and we construct the system with pipelining processing using two CPUs of the Client(PDA) and the Server(PC) in image sequence. The Client(PDA) extracts tentative text regions using Edge Density(ED). The Server(PC) uses both the Multi-1.aver Perceptron(MLP)-based texture classifier and Connected Component(CC)-based filtering for a definite text extraction based on the Client(PDA)'s tentativel99-y extracted results. The proposed method leads to not only efficient text extraction by using both the MLP and the CC, but also fast running time using Client(PDA)/server(PC) architecture with the pipelining processing.

The purpose of this study is to examine the characteristics by design component elements of the facade in elementary school buildings after the 7th educational curriculum. This study choose twenty five elementary school as the subjects of the study. And among many elevations of building, an elevation that is alongside of the schoolyard is chosen because this elevation has the highest visual influence on passers-by. To begin with, this elevation is divided into the roof and the surface of a wall, The roof is divided into roof styles, existence of roof and materials. The surface of a wall is divided into design principles(balance, contrast, rhythm), the formal organization(basic elements and form, and transformation of form), the ornamental composition, materials and colors. The results of the research are summarized as follows: First of all, motifs of classical architecture were well expressed in this period and postmodern tendency had been shown until 2005. After Build Transfer Lease(BTL), however, tendency of classical architecture, contrast by the size of the form and base element by point disappeared. Instead, asymmetrical and flat tendency is expressed. Also, emphasized design of the building elevation appear by basic colors of Munsell, not motifs of classical architecture.

In this paper, a web-based automatic transcription component is designed and implemented for mechanical conversion of revised Korean-to-Romanization notation rule. Specially. we proposes system architecture and algorithms that transcript Korean to Roman automatically after transliterate Korean to phonetic symbol applying phonological principles. The components operate under the web server's script mechanism. and the dictionary for exceptional usage is designed as an accessorial function supported either operating at web server internally or externally. The overall system architecture is presented by UML. specification and pseudo code. The proposed architecture can be implemented in encapsulated service by object oriented component and that can be easily adapted and modified on the internet environment and this system may have many advantages to improve efficiency, library reuse. extensibility at software development.

New trends such as electronic commerce, virtual organizations, e-business applications, etc. increase the dependence of production management on information software systems and contribute to the needs for global, distributed object systems. This paper presents a component based approach for production management systems under the multi-tier distributed information system architecture using UML(Unified Modeling Language), CORBA(Common Object Request Broker Architecture) and XML(eXtensible Markup Language) technologies, and propose rules for mapping a UML class diagram to a XML DTD (Document Type Definition). And we adapt it to the prototype system implementation. The components are implemented by CORBA and we use XML messages for the information exchange between components.

Web-Based instruction system implemented according to CGI based process-oriented. But, in case of system development, theses method is able to take inefficiency with duplication of program code. Also, ofter the development, it takes difficult on the operation and management. In this research, I implement Web-based score processing system by component composition. Applied component model is Java Beans and composition method is to use Chiron-2 architecture. By this method, this research shows the high efficiency - not only structural advance but also low value of cyclomatic complex that measure a maintenance.

Modern enterprise may be in need of developing the right application programs under rapidly changing business environment in fast time-to-market. But Most of enterprise without business process mechanism are very hard to develop the application needed in time when it will be changing their business. To solve this problem, we propose the business process framework based on the closed architecture. This approach is to develop the right application with reusing software modules in time and easily under rapid business process changing/improving through mapping BPM(Business Process Model), SOA(Service Oriented Architecture), and CBD(Component Based Development). we also define 5-Layers of BPF(Business Process Framework), and BNF(Backus Naur Form) for structuring BPF.

Recent Enterprise System has component driven real-time distributed architecture (RDA) and this kind of architecture should performed with satisfying strict constraints on life cycle of object and response time such as synchronization, transaction and so on. Microsoft's .NET platform supports RDA and is able to implement services including before mentioned time restriction and security service by only specifying attribute code and maximizing advantages of OMG's Model Driven Architecture (MDA). In this study, a method to automatically generate an extended model of essential elements in an enterprise-system-based RDA as well as the platform specific model (PSM) for Microsoft's .NET platform are proposed. To realize these ideas, the functionalities that should be considered in enterprise system development are specified and defined in a meta-model and an extended UML profile. In addition, after defining the UML profile for .NET specification, these are developed and applied as plug-ins of the open source MDA tool, and extended models are automatically generated using this tool. Accordingly, by using the proposed specification technology, the profile and tools can easily and quickly generate a reusable extended model even without detailed coding-level information about the functionalities considered in the .NET platform and RDA.
