Monitoring system is essential part in control system to monitor the circumstances of the industrial equipments. Color graphics is generally introduced in the monitoring system for the purpose of effective human interfaces. Hence, color graphic editor is under the implementation to draw graphic elements easily which are utilized in the monitoring situation. In this study, OOP(object oriented programming) is applied in the programming of the software. OOP enables systematic design of algorithm, easy management of the software and easy extension of additional functions. It is reported that the software is under the implementation. Therefore, preliminary structure of the software is briefly discussed in this paper.

Among the method of developing software there are many object-oriented analysis(OOA) techniques, and the new ones are being introduced continuously. The present OOA techniques, however, have difficulty in the identification and the verification of the objects and tend to ignore high-level control aspects of the problem due to the initial partitioning of them on the basis of the data. As a result, it brings inaccurate understanding and faults in the software which is required by users. Therefore the purpose of this paper is to design the TOVERC to verify completeness and consistency through cross-reference between the state transition diagram and the methods of object model in order to reflect the requirements of users in the analysis of software considering this problem.

This paper presents a modeling of railway facilities based on object-oriented software development technique for train operation simulation program. Railway network is decomposed by Line Structure Model and Signal System Model which can be composed to make the train routes and train performance calculation. A brief explanation of class design about these model is provided.

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. These services are expanding the business domain and many users want to access the distributed various spatial data. But, it is difficult to access diverse data sources because of different spatial data format and data access methods. In this paper, we design and implement web GIS services based on the inter-operability and GML (Geography Markup Language) of OGC(Open GIS Consortium) in web distributed environment. Inter-operability provides unique accessing method to distributed data sources based on OLE DB technology of Microsoft. In addition, GML support web GIS services based on XML. We design these GIS services as components using UML (Unified Modeling Language) of an object-oriented modeling language for specifying, visualizing, constructing, and documenting the artifacts of software system. In addition, they also were developed in object-oriented computing environment, and it provides the interoperability, language-independent, easy developing environment as well as re-usability.

본 논문에서는 과거 절차 지향적으로 개발 된 함정 전투체계을 표준화 된 새로운 전투체계 소프트웨어로 변화 시키는 방안을 제안한다. 최근 전투체계 소프트웨어는 새로운 장비의 추가와 기능 변경으로 수정이 빈번이 일어나고 있다. 이러한 확장성관련문제를 해결하기 위해 본 논문에서는 객체 지향 프로그래밍 및 디자인 패턴을 사용하여 전투체계 소프트웨어를 확장성과 유지보유성이 우수한 소프트웨어로 변경하는 방법을 연구하고 실제로 전투체계 소프트웨어 중 교전 모듈에 적용하는 과정을 보여준다. 그리고 함정전투체계에 이러한 표준화를 적용할 경우 어떠한 효용성이 있는지에 대하여 알아본다.

As software technology has made progress, object-oriented CASE tools have become more important. This paper presents the process and similarity in design and implementation of OODesigner, an object-oriented CASE tool, on three platfonns and outlines a kind of generic architecture for the design and the implementation of CASE tools. OODesigner is a tool that was initially developed to support OMT. An initial Unix version has been developed since 1994. In 1997, after the completion of the Unix version, we began developing a Java version and a Windows version supporting UML. The development of a CASE tool is a typical application of the Model-View-ControllerO'vIVC) paradigm. Thus, we obtained a common design pattern among the versions in the MVC point of views. This design similarity can be used to develop several kinds of CASE tools with the corresponding design notations.

Design traceability has been widely recognized as being an integral aspect of software development. Also many projects for software application development have failed because that the projects did not analyze user requirements sufficiently and reflected them in the projects adequately. This thesis proposes a specification and tracing technique for object-oriented analysis and design. The subject of this study is the artifacts of UML development methodology. Therefore, to improve the quality of the software development cycle, in short, the system requirement of customers will be able to respond quickly.

In object-oriented software development, reuse has been studied for the enhancement of software quality and software developer's productivity. But improper modeling in design phase and uncontrolled change during maintenance activities have a problem to reuse a class. In this paper we analyze a semantic cohesion of classes using C++ Program dependency graph, and slice a class with cohesion, so that this method supports the re-estimate of class quality and the extensibility of class. Therefore this proposed method in this paper increases the easibility of the restructuring in the reusable systems, when the developer selects a requested component for a object-oriented program development.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to Seam Framework. Heavyweight and lightweight architecture to resolve the problem with benefits to support the new architecture is a large size distributed object standardization architecture. This architecture, such as the Seam Framework, to provide all of the architecture is possible. The distributed object standardization architecture is most often used in business Seam Framework is well-known architecture. Therefore, this study is based on the Seam Framework large distributed object architecture, design and implementation of standardization software development productivity and the objective is to provide guidance.

As the next significant software abstraction, software agents have generated lots of excitements in recent years because of its promise as a new paradigm for conceptualizing, designing, and implementing software systems. This promise is particularly attractive for creating software that operates in environments that are distributed, open, and complex, such as the Internet. The effort of developing agent systems have, however, suffered from lack of generalized agent architecture because of various properties of an agent and nonexistence of a standard agent architecture. An agent architecture is an important criterion in order to not only identify agents in their domain but also determine the software architecture of the system. The major contribution of the work described here is an object-oriented design of an agent architecture that addresses fundamental properties, which are autonomy and interaction. Object-oriented design method is used for identifying the internal modules of an agent architecture and organizing correlation between the modules are identified.
