  • A computer program for free vibration analysis of plane framed structures has been developed by object oriented programming technique using C" language. The object oriented programming concepts such as object, class, method and inheritance are represented. The static and free vibration analyses for framed structures were satisfactorily performed by this program which consists of TOP, VECTOR, MATRIX, STRU, GUI and other classes. Numerical test shows the validity and capability of the present study which can be expandable to develop a general purpose object oriented finite element analysis program of structures ,res ,

  • In order to utilize remote sensed images effectively, a lot of image classification methods are suggested for many years. But, the accuracy of traditional methods based on pixel-based classification is not high in general. In this study, object oriented classification based on image segmentation is used to classify Landsat images. A necessary prerequisite for object oriented image classification is successful image segmentation. Object oriented image classification, which is based on fuzzy logic, allows the integration of a broad spectrum of different object features, such as spectral values , shape and texture. Landsat images are divided into urban, agriculture, forest, grassland, wetland, barren and water in sochon-gun, Chungcheongnam-do using object oriented classification algorithms in this paper. Preliminary results will help to perform an automatic image classification in the future.

  • 현재 소프트웨어 개발을 위한 방법론은 객체지향에서 컴포넌트지향으로 컴포넌트지향에서 서비스지향 발전되어 오고 있다. 컴포넌트지향 개발 방법과 서비스지향 개발 방법들은 객체지향 UML 모델을 기반으로 분석되어지므로 효율적인 객체지향 분석 방법이 필요하다. 따라서 본 논문에서는 UML 기반의 클래스 식별 및 유스케이스 모델링이 개발자의 직관과 경험에 의존하는 문제점을 보완하여 입력 데이터-처리 프로세스-출력 데이터를 사용한이벤트 기반의 유스케이스 및 클래스 분석 가이드라인과 분석 프로세스를 제안 한다.

  • 자바를 비롯한 객체지향 언어를 쉽게 배우기 위해서는 그 언어가 제공하는 객체지향 프로그래밍 기능만을 습득하는 것만으로는 부족하고, 먼저 프로그래머 자신이 객체지향적 사고를 해야 한다. 그러나 객체지향 개념이 없는 한국어에 길들여진 한국 학생들이 객체지향적 사고를 한다는 것은 쉬운 일이 아니다. 따라서 한국인 학생들에게 객체지향 언어를 교육할 때는 객체지향적 사고에 기반 한 프로그래밍 교육을 실시해야 한다. 본 논문에서는 객체지향 언어를 교육할 때, 먼저 객체지향적 사고 전개 방법을 설명하고, 이를 기반으로 프로그래밍 언어를 사용하여 그렇게 전개한 사고를 표현하는 방법으로 프로그래밍 언어를 교육하는 방법을 소개한다.

  • Purpose: The purpose of this study is to identify the object-oriented metrics which have strong impact on the reliability and fault-proneness of software products. The reliability and fault-proneness of software product is closely related to the design properties of class diagrams such as coupling between objects and depth of inheritance tree. Methods: This study has empirically validated the object-oriented metrics to determine which metrics are the best to predict fault-proneness. We have tested the metrics using logistic regressions and artificial neural networks. The results are then compared and validated by ROC curves. Results: The artificial neural network models show better results in sensitivity, specificity and correctness than logistic regression models. Among object-oriented metrics, several metrics can estimate the fault-proneness better. The metrics are CBO (coupling between objects), DIT (depth of inheritance), LCOM (lack of cohesive methods), RFC (response for class). In addition to the object-oriented metrics, LOC (lines of code) metric has also proven to be a good factor for determining fault-proneness of software products. Conclusion: In order to develop fault-free and reliable software products on time and within budget, assuring quality of initial phases of software development processes is crucial. Since object-oriented metrics can be measured in the early phases, it is important to make sure the key metrics of software design as good as possible.

  • The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).

  • The object-oriented programming languages are widely used in the modern software engineering. The procedural type FEM codes are still used because it is very hard and cost consuming job to re-code them into object-oriented programs. In this study, a FEM program was newly designed and coded with C++, an object-oriented language. Also a special programming technique, auto-loading technique was developed for open structured program, with which the extension and maintenance can be carried out easily. For example, the additions of element libraries to an existence FEM program do not require any modifications of the program.

  • This paper proposes to study on the interoperation between Relation Database(RDB) and Object-oriented database(OODB). It also describes some Characteristics of OODB and introduces the UniSQL system. This paper suggests a new systemcalled URODB (Unifide Relation & Object-oriented database) that will overcome the limits of OODB, improve the shortcomings of the present RDB, and increase the interchangeability in particular.

  • Since container throughput is continually increasing, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations that support user needs require modeling tools that are both easy to use and sufficiently to reflect real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. This paper present the design procedure a simulator for port container terminal that was based on the object-oriented approach. The simulator in order to model and simulate the TC-based container terminals is developed.

  • The modeling components in the object-oriented paradigm are based on the object, not the structured function or procedure. That is, in the past, when one wanted to solve problems, he would describe the solution procedure. However, the object-oriented paradigm includes the concepts that solve problems through interaction between objects. The object-oriented model is constructed by describing the relationship between object to represent the real world. As in object-oriented model the relationships between objects increase, the control of objects caused by their insertions, deletions, and modifications comes to be very complex and difficult. Because the loss of the referential integrity happens and the object reusability is reduced. For these reasons, the necessity of the control of objects and the visualization of the relationships between them is required. In order that we design a database necessary to implement Object Browser that has functionalities to visualize Java objects and to perform the query processing in Java object modeling, in this paper we show the processes for EER modeling on Java object and its transformation into relational database schema. In addition we implement Java Object Parser that parses Java object and inserts the parsed results into the implemented database.
