Based upon XML, a standard document format on the web, there have been many active studies on e-Commerce, wireless communication, multimedia technology and so forth. JML is an XML application suitable for understanding and reusing the source code written using JAVA for various purposes. And it is a DTD which can effectively express various information related to hierarchical class structures, class/method relationships and so on. This paper describes a tool which generates JML document by extracting a comment information from Java source code and information helpful for reusing and understanding by JML in terms of the reverse engineering and a tool which generates a skeleton code of Java application program from the document information included in the automatically or manually generated JML document in terms of the forward engineering. By using the result of this study, the information useful and necessary for understanding, analyzing or maintaining the source code can be easily acquired and the document of XML format makes it easy for developers and team members to share and to modify the information among them. And also, the Java skeleton coed generated form JML documents is a reliable robust code, which helps for developing a complete source code and reduces the cost and time of a project.

어플리케이션 간에 웹서비스를 이용한 통신이 증가함에 따라 SOAP 메시지를 처리하기 위한 웹 서비스 엔진이 널리 사용되고 있다. 웹서비스 클라이언트를 개발하기 위하여 WSDL로부터 바인딩 클래스를 자동 생성하는 Axis 기반의 방법이 흔히 사용되고 있다. 본 연구에서는 모바일 환경의 J2ME Axis 엔진인 MIRAE 베타 버전을 이용한 웹서비스 클라이언트 구축 경험을 소개한다. MIRAE 엔진은 StAX 파서를 사용하며 바인딩 클래스의 자동 생성을 지원하지만, 생성된 클래스가 지나치게 커져서 모바일 환경에 탑재하기에 어려움이 있었다. 본 논문에서는 StAX 파서의 드라이버를 작성하여 메시지로부터 객체를 직접 바인딩 하도록 설계한 메시지 처리부를 소개한다. 이 방법은 필요한 데이터를 수신 SOAP 메시지로부터 직접 가져오고 전송할 때도 프로그램의 데이터를 바로 SOAP 메시지로 만들어 클라이언트의 코드 크기를 줄여준다.

In view of component based development, system development has replaced by assembling existent software components instead of coding and now component assembly research has progressed. In this paper, we formalized the specification using relationship between components for component assembly. If components are assembled through connector, the assembly is available without method call or modification. Therefore in this paper, we formalized the specification and constraint condition for creation of connector which connects components so that the connector is created automatically through the specification and constraint condition.

Model based design method reduces product development period and increases system software safety. In this paper, a BLDC motor controller based on model based design method is designed with Simulink and implemented with auto generated code which is written in C language. To retain the safety of software, this model is implemented according to MISRA AC SLSF guide. The validity of the implemented controller is verified with a real position control experiment, and execution times of each control loops are measured to compare the system performance of the conventional design and the model based design.

Algorithm visualization is useful for program testing, debugging and evaluating, as well as visual aids in education. When teaching algorithms and data structures, showing exact behaviors by graphics or animation is more suitable than just explaining them. Current systems for algorithm animation are limited to a couple of specific applications and need a special environment. In the proposed system, programmer writes source program in C and animator embeds visualization scripts in the appropriate location of the program. Then user can get an animation code in form of SVG and see a graphical representation on the web browser. Generated SVG animation code is platform independent and can also interact with other XML applications or HTML.

This paper proposes a novel algorithm for the efficient classification and annotation of medical images, especially X-ray images. Since X-ray images have a bright foreground against a dark background, we need to extract the different visual descriptors compare with general nature images. In this paper, a Color Structure Descriptor (CSD) based on Harris Corner Detector is only extracted from salient points, and an Edge Histogram Descriptor (EHD) used for a textual feature of image. These two feature vectors are then applied to a multi-class Support Vector Machine (SVM), respectively, to classify images into one of 20 categories. Finally, an image has the Annotation Code Array based on the pre-defined hierarchical relations of categories and priority code order, which is given the several optimal keywords by the Annotation Code Array. Our experiments show that our annotation results have better annotation performance when compared to other method.

It has limits that system administrator deals with many problems occurred in systems because computing environments are increasingly complex. It is issued that systems have an ability to recognize system's situations and adapt them by itself in order to resolve these limits. But it requires much experiences and knowledge to build the Self-Adaptive System. The difficulty that builds the Self-Adaptive System has been problems. This paper proposes a technique that generates automatically the codes of the Self-Adaptive System in order to make the system to be built more easily. This Self-Adaptive System resolves partially the problems about ineffectiveness of the exceeded usage of the system resource that was previous research's problem and incorrect operation that is occurred by external factors such as virus. In this paper, we applied the proposed approach to the file transfer module that is in the video conferencing system in order to evaluate it. We compared the length of the codes, the number of Classes that are created by the developers, and development time. We have confirmed this approach to have the effectiveness.
