본 논문에서는 UML을 이용하여 소프트웨어 아키텍처를 표현하는 방법을 소개하고, 복수의 뷰를 통한 아키텍처를 문서화하는 방법을 설명한다. 무엇보다 논문의 핵심은 UML의 다이어그램이 복잡하여 특별한 편집도구 없이는 표현이 불가능한 점을 반영하여, UML의 표현방법을 개선하고 이를 아키텍처뷰의 표현에 적용한 점이라고 할 수 있다.

It is more emphasized on the software architecture recently, as the scale of a software becomes huge and the need of the software management becomes more dynamic. Software architecture is a representation of structures of software framework just like the blueprint of building architecture. In order to describe software components and their relationships accurately and entirely, software architecture is documented in some different views, by using of modeling tools. UML(Unified Modeling Language) is a software modeling tool recently used for documentation of software and as well as software architecture. Nevertheless, what we have to agree with is that UML is not easy to use and its standard changed continuously. And also the documentation with UML is found some burden because of its difficulties in learning and using. This inconvenience enforces us to purchase and use commercial tool for UML. The study introduces the architecture views refined from 4+1 Views for architecture design and shows how to represent architecture views for software architecture. Especially, we simplifies UML diagrams for the purpose of focusing on architecture views and facile manipulation. At the end, we add the evaluation on the refined architecture views as well as refined UML diagram.

As processor technology advances, it has accelerated ISA extensions and increased the complexity of micro-architectures, leading to a continued rise in the importance of processor validation techniques. Recently, various fuzzing techniques have been introduced to discover undocumented instructions, and this study highlights the shortcomings of existing undocumented instruction fuzzing techniques and presents our observation on error cases in the latest processors from Intel and AMD. In particular, we analyzes the causes of false positives resulting from the fuzzer incorrectly judging CPU instruction length and proposes the length determination technique based on instruction execution information to improve accuracy.

소프트웨어 디자인 패턴(Design Pattern)은 좋은 설계나 아키텍처의 재사용을 도와주며, 이미 만든 시스템의 유지보수나 문서화도 개선해 준다. 패턴화를 통해서 클래스의 명세를 정확하게 하며, 객체간의 상호작용 또는 설계의 의도 등을 명확하게 정의할 수 있게 해준다. 사용자가 필요 시 디자인 패턴을 쉽고 편하게 UML 모델링 도구에 적용할 수 있다면 생산성 및 품질 개선에 크게 이바지할 컷으로 판단된다. 본 논문은 UML 모델링 도구에 사용자 정의형 패턴을 쉽게 적용할 수 있도록 하는 기능을 설계하여 구현한 결과를 제시한다

자바 프로그램언어를 이용한 개발이 많아지면서 사용할 수 있는 소프트웨어도 많이 배포되고 있다. 오픈 된 자바에 관련된 소프트웨어는 특정 부분에서 사용하는 기능을 개발한 것도 있지만 개발환경을 제공하는 프레임워크가 많은 부분을 차지한다. 개발자는 소프트웨어를 개발할 때 하나이상의 프레임워크를 선정하여 소프트웨어 아키텍처를 설계하게 되는데 각 프레임워크의 역할은 모든 프로그램이 동일하지는 않다. 그래서 프레임워크간의 관계 및 역할 등의 정보가 문서화가 이루어져서 개발자 뿐 아니라 사용자에게 정보를 제공해야 한다. 특히 오픈 소스는 빈번하게 업그레이드되어 변화하는 프레임워크 정보를 이해하지 못하면 매우 혼란스럽게 된다. 본 연구는 자바 오픈 프레임워크를 이용하여 소프트웨어를 개발하려고 할 때 프레임워크의 정보 관리 및 소프트웨어 아키텍처를 설계 후 작성해야 하는 문서의 표준안을 제시한다. 이는 개발자는 개발된 소프트웨어의 구조를 표준화된 문서로 배포하면 사용자는 그 문서를 활용하여 소프트웨어의 구조 뿐 아니라 오픈 소스 프레임워크의 역할과 환경정보를 빠르게 이해하고 향후 효과적인 유지보수를 하는데 도움을 줄 수 있다.

Android applications market has increased rapidly due to the popularity of smart phones. In order to high competitiveness in the application market should be high productivity, reduce cost. And short development cycle is required because of increased the android applications demand. Owing to develop applications in short time, the requirements analysis, design process are able to omitted. But in the case of reuse application at development phase, involved many problems because omit document or design. so target of this paper is android application source code that omit document or design. we propose architecture recovery techniques from android application source code by reverse engineering with identify functions are reused. We expect that increase productivity and reduce development cost, smooth maintain by proposed technique.

In our country security industry biz model analysis methodology fragmentary theory exists, but it is hard to find a comprehensive analysis methodology. Biz model analysis IT companies the external factors and internal factors to integrate the information gathered about the comprehensive analysis of the development of an information system are required. Information support system early in the software architecture of the system design decisions early decision as the design, development, testing, maintenance, has a lasting impact on the project as a guideline in the development of a framework of design abstraction. BMO evaluation support information systems architecture designs system purposes. The mission must support the execution. Information system stakeholders to determine the mission and the environment. All information systems architecture shall have architecture. Technology architecture should be documented with each other can be used. Determine the architecture based architecture descriptions are presented.

The Unified Modeling Language becomes popular to specify, visualize, construct, and document software-intensive systems, especially in supporting the design phase of software engineering. Most of designs in UML have focused on firm designing of software system structure. Recently, some researches have raised additional demands in many emerging complex software systems, such as aspect-oriented design. In this paper, we work on the dynamic aspect of policy-driven architecture. We present a UML-based high-level modeling of policy-driven management which is applicable in various application domains. In order to manage a number of activities of applications, dynamics and flexibility should be supported with policies consistently on different resources in the same context. Thus, a methodology of meta-modeling to represent dynamic aspects of policy-driven architecture is studied. Based on our methodology, we could achieve meta-modeling to develop a number of policy-driven management applications.

This study proposes the Web-based GIS system based on distributed object management and conceptualise system architecture and its methods specifications through UML(unified modeling language). By using class diagram and creating prototype based on UML and reverse engineering, our conceptual shape file model is proposed to illustrate an integrated architecture. Through system analysis and software configuration management, this study enables to not only improve pliable capabilities for problematic domains and increase abilities for analytical domains when user requirements are dynamic, but also assist effective and consistent maintenances of large software systems.
