Traditional database systems have been used models supported for the operations and relationships based on simple interval. video data models are required in order to provide supporting temporal paradigm, various object operations and temporal operations, efficient retrieval and browsing in video model. As video model is based on object-oriented paradigm, I present entire model structure for video data through the design of metadata which is used of logical schema of video, attribute and operation of object, and inheritance and annotation. by using temporal paradigm through the definition of time point and time interval in object-oriented based model, we can use video information more efficiently by time variation.

If there is redeveloping into the system applying the object-oriented paradigm, productivity Improvement of software through reuse would be accomplished and maintenance cost be reduced. When a procedure-oriented system is transformed to a type applying the object-oriented paradigm, various techniques are studied to extract objects from source code automatically or semi-automatically. However, it is not easy to extract conceptuat objects when those techniques are applied, This problem entails another problem which drops the conceptual integrity of the extracted objects. In this paper, we suggest an object extraction method and tool development to resolve the problem occurring at the time when thc pr"~r"m, dcveloped through procedure-oriented is transformed to an object-oriented system. The suggested method allow to extract the desired objects using object modeling for various application domains of the real world given source code and design recovery information. During the extraction process, functionality and global variables of the source code as well as its intcrface arc rigorously analyzed. This process can enhance the conceptual integrity of the objects and make easy to construct class hierarchies.

Re-engineering has the potential to improve software productivity and quality y across the entire life cycle. It involves improving the software maintenance process and improving existing systems by applying new technologies and tools to software maintenance. Re-engineering can help us understanding existing systems and discover software components(e.g., design structure, data structure that are common across systems. These common components then can be reused in the development (or redevelopment )of systems, thereby significantly shortening the time and lessening the risk of developing systems. The Object-Oriented paradigm has been known to improve software maintainability. There still exist many problems in recognizing object, attributes and operations that are conceptually integrated and constructing of object class. In this paper, we propose a method that defines a fundamental theories of re-engineering and a concept recognition for object- oriented paradigm. We also describe the re-engineering tool that translates the existing procedure-oriented program into object-oriented system. This tool has a strength to solve the conceptual integrity problem in object-oriented recognition.

This paper represents a new powertrain simulation methodology using the object-oriented programming paradigm. The advantage of the object-oriented is the module interchangeability and simulation flexibility. Powertrain subsystems and controller modules are implemented using the MEX files in MATLAB Simulink in this paper, preserving module interchangeability. Currently, the required CPU time on a 75MHz Pentium PC is about three times the real time. It is anticipated that the "Automotive Powersystem Toolbox" being developed in this research would be of much utility in designing subsystem controllers as well as in designing subsystem mechanicals.chanicals.

Object-oriented paradigm has required the fundamental changes in the developers' practice and orientation. However. the relevant literature has not still provided the solid practical methodology but created some myths regarding Use Case modeling. In this study. we attempt to 'demythologize' some key aspects of Use Case Modeling by describing what we have observed in our research and practice. In order to identify the developers' perceptions. the survey methodology was utilized. By discussing the differences between what must be done and what has been done. this study provides rich insights into the better understanding of the Use Case modeling and the successful development of object-oriented systems.

Family policy and parents support policy are similar in that they are both object-oriented, not function-oriented. An object-oriented policy, different from a function-oriented policy, is demander-oriented in that it combines the existing policies from the object-perspective. Parents support policy and family policy are very similar in that they are both object-oriented policies and emphasize the perspective of the demanders: the parents and family. As is the case for all policies, if the ministries concerned with the policies are different, the projects are promoted from different delivery systems, so it is difficult to link them together. However, it is essential to relate the two policies because a partnership between families and schools, the subjects of the policy, is the basis of healthy family and a healthy society. Therefore, this research analyzes the current family policy and parents support policy, and examines the necessity and possibility of relating the two policies. This analysis is meaningful in that it seeks consilience between the policy areas, and seeks a new demander-oriented paradigm construction system.

Recently, the object-oriented design is the major paradigm for software development. Most systems are following this paradigm, but the past studies for a video conversation domain were not based on full-scale object-oriented design. Thus, this paper presents an systematical architecture design using UML for a video conversation system that is well-known and has high rate of usefulness. It analysis a video conversation system that has much demand of service as systematical functional/non-functional requirements, and the object-oriented design applying '4+1 View Model' guarantees the reusability of a component and makes it possible to extend a system by adding components as needed. Consequently, it is expected that the components of video conversation system designed by this paper will be useful the other video conversation systems and will be expanded to web environment.

Measurement of the object, messages, clones, capsulation, inheritance, etc. that are conventional object-oriented paradigm characteristics as a method of measurement of the complexity of object-oriented programs has been reported. In this paper, the measures that are helpful to designing and coding of JAVA program, which is the representative language of object-oriented programs, are applied to six measures(i,e., Halstead's Program Volume, Program Level, Program Impurity, Macabe's Cyclomatic Number, Handerson-Seller's lock of cohesion in method and Sullivan's PVG.) suggested in the present study by referring to several actual programs as example for comparative analysis.

As a product structure or BOM(bill of material) of products is hierarchically structured, the design based on the concept of relational data base modeling causes low performances in data search or processing. For this reason, an object-oriented approach to designing a product structure is proposed in this paper. Using Rumbaugh's OMT (Object Modeling Technique) method, classes of parts, BOM structure, options, and models are defined and their class-relationship diagrams are proposed. For the representation of the BOM structure suitable for the object-oriented paradigm, a new data architecture called the BOM item class is suggested. It is expected that the proposed data structure ensures better reusability and expandability due to the modularity.
