This paper proposes a design procedure to develop the object-oriented simulator of port container terminal. The design methodology uses an object-oriented approach to support an object-oriented simulation and the design procedure consists of object scheme and event scheme. The object-scheme is a procedure to determine the structure of material flow objects and information flow objects and a relation diagram between objects that have attributes and methods. The event scheme is a procedure to define methods and to connect messages of objects. We assume that the container terminal system consists of gate, container yard, and berth and the equipment used in the container terminal are container cranes, transfer cranes, yard tractors, and trailers.

Microarray information system is a complex system to manage, analyze and interpretate microarray gene expression data. Establishment of well-defined development process is very essential for understanding the complexity and organization of the system. We performed object-oriented analysis using Unified Modeling Language (UML) in specifying, visualizing and documenting microarray information system. The object-oriented analysis consists of three major steps: (i) use case modeling to describe various functionalities from the user's perspective (ii) dynamic modeling to illustrate behavioral aspects of the system (iii) object modeling to represent structural aspects of the system. As a result of our modeling activities we provide the UML diagrams showing various views of the microarray information system. We believe that the object-oriented analysis ensures effective documentations and communication of information system requirements. Another useful feature of object-oriented technique is structural continuity to standard microarray data model MAGE-OM (Microarray Gene Expression Object Model). The proposed modeling e(forts can be applicable for integration of biomedical information system.

The object-oriented methods are being rapidly accepted as the solution for the software crisis. Object-oriented systems are composed of the integration of independent object modules; their merits are such that it is possible to reuse objects already developed, and that, when changes are required, modifications are restricted to some independent objects such that their affects to other objects are so little. In this paper, we deal with the macro assembler for next-generation microprocessors which has the merits of object methods. Whenever a microprocessor is newly developed, new assembler should be developed or the existing assembler be modified. In the former, it leads to the loss of time and money by the repeated developments, and, in the latter, it causes the problem of inefficient productivity since other modules are to be analyzed for the affections followed by modifications of one module, especially in the existing assemblers. To resolve these problems, the object-oriented macro assembler suggested in this paper consists of independent objects separable such that it shows reusability and reduces the inefficient productivity by minimizing the affects to other objects. Moreover, the object-oriented macro assembler integrates a macro pre-processor into an assembler, and uses automata for analyzing input streams to reduce the compile time.

While object-oriented models are effective in achieving sharing and code reusability, they unfortunately lack a mechanism for giving scope to objects. We revisit an object-oriented model in which each object can be given a scope. We illustrate the usefulness of this model by showing that it supports the notion of parameterized modules without difficulty.

A computer program for matrix structural analysis by object-oriented programming technique using $C^{++}$ language has been developed. Object, class, method and inheritance which are used in object-oriented programming are illustrated using a graphical representation. The matrix operations and the structural analysis by matrix displacement method were satisfactorily performed by the proposed program. Numerical tests demonstrate that this proposed program can be widely used for the matrix structural analysis for personal computers.s.

To analyze the applications of all types of mechanical systems, general purpose analysis programs have been developed and commercialized. However, it is customary to develop and use customized programs even though they sometimes require more work than a general purpose program. A customized program is simplified to adapt to a particular application from the beginning, is designed for small computers, and developed with hardware-in-the-loop in mind so it can be applied effectively. By adding design knowledge and bundling know-how to an analysis program, analysis time can be reduced. And because an analysis has to work in conjunction with other analysis programs, a proprietary program that the user can easily modify can be useful. In this thesis, a multi-body dynamics analysis system is presented using one of the most useful programming techniques, object-oriented concept. The object-oriented concept defines a problem from the physical world as an abstract object, an abstract model. The object becomes encapsulated with the data and method. Simulation is performed using the object's interface. It is then possible for the user and the developer to modify and upgrade the program without having particular knowledge of the analysis program. The method presented in this thesis has the following advantages. Since the mechanical components of the multi-body system converts independent modeling into a class, the modification, exchange, distribution, and reuse of elements are increased. It becomes easier to employ a new analysis method and interface with other S/W and H/W systems. To employ a new analysis method, there is no need to modify elements of the main solver and the Library. In addition, information can be communicated to each object through messaging. It makes the modeling of new elements easier using inheritance. When developing a S/W for the computer simulation of physical system, it is reasonable to use object-oriented modeling. Also, for multi-body dynamics analysis, it is possible to develop a solver that is user-oriented.

현실세계의 복잡한 데이타모델을 표현하고 관리하는 객체지향 데이타베이스 관리 시스템에서는 모든 객체들에 대한 접근과 조작이 객체관리기에 의해 처리된다. 본 논 문에서는 객체지향 질의처리를 위한 객체관리기의 호출함수와 의미를 규정하는 객체 관리기 인터페이스의 설계 원칙을 제안하고, 이에 따라 객체관리기 인터페이스를 구현 한다. 구현된 객체관리기 인터페이스는 질의처리부와 객체관리부를 서로 독립적으로 개발할 수 있는 환경을 할 뿐만 아니라, 다양한 응용의 적용을 가능하게 하며, 사용자 에게 효율적 접근 방법을 제공한다.

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.

최근 다양한 분야에서 폭넓게 활용되고 있는 XML 문서는 유연하고도 개방적인 특성으로 인해 정보교환이나 전송을 위한 수단으로 널리 이용되고 있다. 한편 XML 문서를 위한 시각적, 직관적 질의 언어인 XML-GL은 질의에 대한 의미와 결과 문서의 구조를 시각적으로 표현할 수 있기 때문에 XML 문서에 대한 구조 검색과 정보의 공유가 용이하다. 그리고 UML은 정해진 표기법과 다양한 다이어그램을 이용하여 객체지향 분석과 설계를 위한 도구로 사용되고 있다. 따라서 본 논문은 XML-GL의 데이터 모델인 XML-GDM을 기반으로 표현된 XML 문서를 UML 클래스 다이어그램으로 사상하기 위한 새로운 객체 모델링 방안을 제안한다. 이를 통해서 XML 문서를 직관적인 방법으로 객체지향데이터로 변환하고 저장/관리할 수 있다. 또한 객체지향 검색방법을 적용하면 보다 효율적으로 XML 문서를 검색할 수가 있다.
