본 논문은 함정 전투체계의 아키텍처를 설계하고 세부 기능을 분석 및 구현하기 위한 방안 연구를 위해 작성되었다. 함정 전투체계와 같이 복잡도 높은 대규모 시스템에서 문서 산출물에 근거한 개발은 산출물 간 유기적인 연결이 어렵고 요구조건의 변화에 따른 영향 요소 식별 및 반영이 어렵다는 단점을 갖는다. 이에 대한 대안으로 제시된 모델 기반 개발 방법론을 함정 전투체계에 적용하기 위해 미 국방 분야 표준 아키텍처인 DoDAF와 이를 지원하는 UPDM, 시스템 엔지니어링과 소프트웨어 엔지니어링 분야의 모델링을 지원하는 SYSML/UML을 살펴보고 함정 전투체계에 적합한 모델 구성 및 각 개발 단계 별 모델링을 수행하는 절차에 대한 가이드라인을 제시한다.

UML(Unified Modeling Language)은 범용 모델링 언어로 일관된 표기형식을 제공하여 표준 모델링 언어로 자리 잡았다. 그러나 특정 도메인에 종속적이지 않은 UML의 특징 때문에 기존의 표준 UML의 표현 방식으로는 특화된 분야의 상세한 아키텍처의 모델링이 어렵다. 이를 해결하기 위해 UML은 새로운 개념을 추가할 수 있는 확장 메커니즘을 제공하며, 이를 통해 특정 플랫폼이 가지고 있는 특별한 의미를 표현한 아키텍처 모델링이 가능하다. 본 논문에서는 UML의 확장 메커니즘을 이용하여 윈도우폰7 애플리케이션의 모델링을 위한 프로파일을 정의한다. 이를 위해 윈도우폰7의 특성을 분석하고 확장요소를 추출하여 이를 기반으로 UML을 확장하였다. 이를 이용하여 윈도우폰7의 애플리케이션 개발에 특화된 모델링을 할 수 있다.

Today raises its head on the issue of interoperability caused by the complexity of the embedded software and the diverse development environment about SUGV(Small Unmanned Ground Vehicle). So, we propose to adopt the original MDA mechanism for this heterogeneous embedded development. To solve this problem, we apply for developing SUGV with MDA(Model Driven Architecture) using the original UML profile mechanism. Through this method, it can be semi-automatically transformed into TSM(Target specific model) after modeling TIM(Target Independent Model). Then we can also automatically generate the heterogeneous source codes. Therefore it will be reduced the development cycle and effort of the heterogeneous systems. We verify the benefits of our proposed approach and the reliability through analyzing the generated codes.

The complicated embedded system for multi-tasking requires RTOS(real-time operating system). It uses the optimal OS and processor to each embedded system on the heterogeneous development environment. This paper is proposed to use UML profile of OS API and Processor Configuration, instead of cross-compiling for developing the heterogeneous embedded system. This reduces the development time and cost through generating the automatic source code with the profile information of each embedded system. We generate and port the code after modeling the two heterogeneous real time operating systems (brickOS and uC/OS-II) and the processors (Hitachi H8 and Intel PXA255) with our proposed profile of the heterogeneous embedded system.

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.

EDI (Electronic Data Interchange) has been widely utilized to support Business Activities since it has such advantages as fast transfer of information, less documentation work, efficient information exchange etc. Recently e-business environment has urged the traditional EDI system to be changed to ebXML framework. To apply the ebXML framework to a certain industry, it is required to implement Business Process (BP), Core Component (CC), Collaboration Protocol Profile (CPP), Collaboration Protocol Agreement (CPA), Messaging system etc. We have selected the port and logistics industry as a target domain to apply ebXML framework, since the EDI usage ratio of it is relatively higher than other industries. In this paper, we have analyzed the current status of EDI system and transaction processes in the port and logistics industry. We have defined the business process that will be registered in the registry/repository, the main component of ebXML framework, using UN/CEFACT modeling methodology. And Business Collaborations, Business Transactions, Business Document Flows, Choreography, Pattern, etc. are represented using UML according to UN/ CEFACT modeling methodology, to apply ebXML Framework to the port and logistics distribution industry. Also we have suggested the meta methodology for applying the ebXML framework to other industries.

In this paper we present an integrated design methodology for relational database based on object-oriented analysis and design. The integrated design methodology is based on business profile and has six phases. In the first phase, business use cases are identified and described by macroactivity diagrams and then the macroactivity diagrams are transformed to detailed business activity diagrams by using objects, object flows and business worker's responsibilities. In the third phase, the detailed business activity diagrams are transformed to business class diagrams that describe the static structure of the entire business system based on detailed business activity diagrams. In the four phase, the business class diagrams are transformed to class diagrams that represent the initial conceptual model of the target relational database. In the five phase, we add additional transformations on the class diagrams with generalization and specialization of associations, roles, activities, additional classes and redundant associations. Eventually, the final class diagrams are transformed to relational database schema. The methodology presented in this paper by applying that proposal for organic connection between object-oriented analysis and design methodology and relational database design methodology. And it will be able to deal with integration management. By the integrated design methodology, we can make more easily software systems based on relational database. In the case study, proposal integrated design methodology applied for a visa issuing system.

The role of a GIS as a tool for a national information infrastructure can best be fulfilled once GIS standards are implemented. In this paper, we have identified what the contents of GIS standards in other countries are, and what should be the future direction for implementing a nation's GIS standards. Based on a detailed review on GIS standards in the USA, Australia, Japan and the United Kingdom, we derived the following: (1) A nations's GIS standards should include both geographic information content standards and geographic information service standards: (2) A nation's GIS standards should be a profile of ISO GIS standards: (3) Each GIS standards should be developed on the bassis of the Entity-Relationship Model using Unified Modeling Language: and (4) Experts in GIS should pay much more attention on studies on GIS service standardization. As for building the national GIS Standards for Korea, we recommend both GIS Content Standards and GIS Service Standards be simultaneously developed. GIS Content Standards include geographic feature content standard, feature classification standard, portrayal standard, rules for application standards, spatial reference model and terminology. GIS Service Standards include standards for data sharing such as metadata standard and transfer standard, quality standard, quality principle and portrayal standards.
