  • 소프트웨어 산업의 발전에 따라 개발 수요의 충족 및 개발 효율성의 증대를 위해 다양한 개발 방법론과 개발 지원 도구들이 등장해 왔다. 그러나 데이터베이스 응용 소프트웨어(Database Application Software, DB-App)의 개발이 활발함에도 불구하고, 해당 분야 개발의 효율을 도모하는 방안에 관한 연구는 미비한 실정이다. DB-App의 소스 코드(Source code)에는 쿼리(Query)문이 빈번하게 사용되지만 작성 과정에서 오류가 발생하기가 쉽고 관리에 대한 어려움이 있다. 이는 개발 효율을 저하시켜 비용을 증가시키는 요인이 된다. 본 논문에서는 다양한 데이터베이스와 프로그래밍 언어로 개발되는 DB-App 개발을 지원하기 위한 방법을 기술하였으며, 사용자의 설정에 따라 쿼리문을 포함한 소스 코드를 생성하는 도구를 설계하였다.

  • Software product lines are to attain the rapid development of qualify applications by concretizing the general components populated in software assets and assembling them according to the predefined architectures. For supporting the construction of the software product lines, this paper proposes a component code generation techniques based on GenVoca architecture and XML/XSLT technologies, In addition, CompGenX(Component Generator using XML), a component code generation system, is proposed on the basis of this techniques. By providing reconfigurability of component at the time of code generation, CompGenX allows the reusers to create the component source code that is appropriate to their purpose, In this system, the process of the component development is divided into two tasks which are the component family construction task and the component reuse task, For the component family construction, CompGenX provides the feature modeling tool for domain analysis and the domain architecture definition tool. Also, it provides the tool for building the component configuration know1edge specification and the code templates, For the component reuse task, it offers the component family search tool. the component customizing tool and the component code generator. Component code generation techniques and system in this paper should be applicable as basic technology to build the component-based software product lines.

  • The system optimization is a technique that changes the structure of the program in order to extract the duplicated modules without changing the source code, reuse of the extracted module. Structure-oriented development and object-oriented development are efficient at crosscutting concern modular, however can't be modular of crosscutting concept. To apply the crosscutting concept in an existing system, there is a need to a extracting technique for distributed system optimization module within the system. This paper proposes a method for extracting the redundant modules in the completed system. The proposed method extracts elements that overlap over a source code analysis to analyze the data dependency and control dependency. The extracted redundant element is used to program dependency analysis for the system optimization. Duplicated dependency analysis result is converted into a control flow graph, it is possible to produce a minimum crosscutting module. The element extracted by dependency analysis proposes a system optimization method which minimizes the duplicated code within system by setting the crosscutting concern module.

  • Computational fluid dynamics analysis was performed for the case 3 of the EFD-CFD workshop. Solvers were used for three commercial CFD codes(Star-CCM+, Fluent and CFX) and an open source CFD code(SU2). The grid were generated four types depending on the total cells using commercial grid generation code(Pointwise). Mach number of 0.4 and 0.8, 2 degree angle of attack and Mach number of 0.9, 1 degree angle of attack were calculated. Similar pressure coefficient curve and normal force coefficient were showed from the coarse grid to fine grid of four codes. But there is a difference in the drag coefficient. The position of the shock wave was predicted forward as the discretization order increased in calculations using Star-CCM+ and Fluent. The computation time to converge, Fluent, Star-CCM +, CFX are in order, and SU2 takes much time to converge.

  • A C-to-SystemC synthesizer which processes the input behavior according to high-level synthesis, and then transforms the synthesis result into SystemC module code is implemented in this paper. In the synthesis process, the input behavioral description in C source code is scheduled using list scheduling algorithm and register allocation is performed using left-edge algorithm on the result of scheduling. In the SystemC process, the output from high-level synthesis process is transformed into SystemC module code by combining it with SystemC features such as channels and ports. The operation of the implemented C-to-SystemC synthesizer is validated through simulating the synthesis of elliptic wave filter in SystemC code. C-to-SystemC synthesizer can be used as a part of tool-chain which helps to implement SystemC design methodology covering from modeling to synthesis.

  • 영역지향 프로그래밍(Aspect-Oriented Programming)은 소프트웨어의 성능을 향상시키고 유지보수에 많은 이점을 가지는 새로운 프로그래밍 방법론이다. 하지만 영역지향 프로그래밍 방법으로 소프트웨어를 개발하기 위해서는 Aspect를 지원하는 새로운 영역지향 프로그래밍 언어를 사용하거나 레거시 시스템에 Aspect를 적용할 경우에 소스코드의 재 컴파일등과 같은 문제점을 가지고 있다. 이에 본 논문에서는 레거시 시스템에 Aspect를 동적으로 결합할 수 있는 동적결합 메커니즘을 제안한다. 이를 위하여 Aspect의 행위와 결합 정보를 가지는 Connector를 생성하고, 생성된 Connector는 코어클래스의 위임자로서 역할을 수행하게 되는 동적결합 가능하게 하는 메커니즘을 제안한다.

  • A purpose of the object-oriented programming is to promote reuse and development time, and to improve software quality. A way for this purpose is using a design information well-defined and tested in previous time when developing software. Such design information is called design patterns. The design patterns are descriptions of abstract solution to recurse software design problems In a systematic and general way. But because the design patterns are descriptions of abstract solution, the specification and application of patterns generally rely on manual implementation and is applied to various forms. As a result, we need to spend a lot of time to develop software program not only because of difficulty in analyzing and applying to patterns consistently, but also because of the frequent programing faults. And because the applied design patterns don't express inside application visually, it is difficult to analyze and test for this design patterns. In this paper, we propose automatic source code generating technique to be able to efficiently apply the element of design patterns when developing application. And we show a way to analyze and use the applied design patterns in application. As a result, the design patterns in application provide the consistent structure and efficiency, and make analysis and using effect increased.

  • As software industry is rapidly evolving, IT business enterprises have been meeting with cutthroat competition in developing software. As software reusability, time to market, and maintainability are considered as a competitive edge, software component techniques have lately attracted considerable attention. Currently, although there are some supporting tools for developing software components, they do not have tight connections among component developing processes such as component identification, component modeling, detailed design, code generation, deployment, and testing. And it is restrictive for users to construct various scales of components on component platform architecture. In this paper, we provide an implementation and a design of a supporting tool for constructing platform-independent software components, which covers all development lifecycles of components. In the phase of component modeling, platform independent, conceptual components are identified from domain model information in the view of system partitioning. Detailed design and implementation of a component are performed on the J2EE platform architecture. And the changes on the design model and source codes are consistently managed by using round-trip techniques.

  • A widget is a small application running by the users' favorite services, so they are provided with web contents without explicitly visiting the web site. Although widgets can be easily implemented with Open APIs, only a few web sites provide them because of refactoring the structures of web resource to supply Open APIs to the widget developers. This paper presents an Open API Proxy Server System for widget services. The system consists of two components: an Open API Source Code Generator and an Open API Proxy Server. The Open API Source Code Generator provides a Graphical User Interface (GUI) for users to generate the Open APIs of user's choice and sends the Open API source code generation request to the Open API Proxy Server. The Open API Proxy Server using the HTML Table Processing Library receives the HTML web page from web site and extracts useful information from the target HTML table. The proxy server converts the extracted data into the corresponding XML document which becomes available through the Open API. We verify the operation of the proposed system through experiments with the HTML tables in the example web sites.
