In this papers, it will be introduced that power quality analysis software design including investigation of mutual relation between power quality data and mechanism for getting data from power quality database according as based on object-oriented methodology. The UML which is only a language and so is just part of a software development, may be used to visualize, specify, construct, and document the artifacts of software-intensive system.

In recent years, object-orientation is rising to notice as a new paradigm for developing software. This paper suggests the diagramming technique and a tool for developing C++ program effectively. This technique can represent the modularity and the interactions of classes definitely by emphasizing the characteristics of classes of C++. It can do the direct mapping from the logical idea to the physical screen image, so programmers can reuse the design resources in design phase as well as transforming the resources into chode in the implementation phase.

As a representative reuse paradigm, the theme of service-oriented Paradigm (SOC) is largely centered on publishing and subscribing reusable services. Here, SOC is the term including service oriented architecture and cloud computing. Service providers can produce high profits with reusable services, and service consumers can develop their applications with less time and effort by reusing the services. Design Patterns (DP) is a set of reusable methods to resolve commonly occurring design problems and to provide design structures to deal with the problems by following open/close princples. However, since DPs are mainly proposed for building object-oriented systems and there are distinguishable differences between object-oriented paradigm and SOC, it is challenging to apply the DPs to SOC design problems. Hence, DPs need to be customized by considering the two aspects; for service providers to design services which are highly reusable and reflect their unique characteristics and for service consumers to develop their target applications by reusing and customizing services as soon as possible. Therefore, we propose a set of DPs that are customized to SOC. With the proposed DPs, we believe that service provider can effectively develop highly reusable services, and service consumers can efficiently adapt services for their applications.

망 운용에 있어서 망 관리 시스템은 다양한 네트워크 장비의 증가로 인하여 점점 더 중요한 위치를 차지하고 있다. 과거 망을 구성하는 요소는 네트워크 장비로 국한되었지만 현재는 서비스를 지원하는 데몬(Daemon) 등 장비 외적인 요소까지 속하게 되어 더욱 복잡해 지고 있다. 기존의 망 관리 시스템은 SNMP(Simple Network Management Protocol)나ICMP(Internet Control Message Protocol) 프로토콜을 사용하였으나 이 기술만으로는 데몬과 같은 장비 외적인 요소들까지 제어, 관리하지 못했다. 반면. TELNET등과 같은 기능을 추가적으로 이용할 수 있다면. 보다 쉽게 망 정보를 얻을 수 있는 장점이 있어 기존의 망 관리 시스템에서 지원하지 못했던 기능의 한계점을 극복할 수 있다. 이에 본 논문은 객체지향기술(OOT : Object­Oriented Technology)을 도입하였다. 클래스(Class)는 고유한 특성을 가지는 관리 대상 종류를 선언한 것이고. 관리 대상은 네트워크 장비 뿐만 아니라 데몬이나 지역, 부서등과 같은 추상적인 대상이 포함되며 이는 객체(Object)를 의미한다. 또한. 상속(Inheritance) 개념을 도입하여 중복요소를 없앴으며, 클래스의 메소드(Method)에 관리 대상을 처리할 수 있는 기능을 정의하였다. 기능 정의에는 SNMP와 TELNET. ICMP등을 내부적으로 이용하여 구현된 스크립트(Script)를 이용하였다.

In this paper, a controller is designed for efficient controlling of video data with object-oriented feature. The need of controlling video data in an object unit is on the rise for the reason of rapidly growing demand for high-quality video services. We propose a programmable architecture with stack buffers which can minimize a scheduling overhead by having separate buffes for genral data and return addresses. The buffers are veyr useful for move and copy operations for multitasking and task switching. The controller offers extended instructions that process several data types including 32bit integrer type. Operation speed of the controller is from 77MHz to 44MHz.

The management of network in TMN defines and manages the objects which are the operating system and communication equipments in network. GDMO is used to describe thoseobjects. GDMO is not directly used for managing network, but translated into a language with object-oriented paradigm. This paper presents design and implementation of the translator which automatically translates the specification of GDMO to the object-oriented language for generating MIB(Managment Information Base). And the system includes various graphic use interface to enhance the development environment of GDMO.

The current focus of development in industrial Computational Fluid Dynamics (CFD) is integration of CFD into Computer-Aided product development, geometrical optimisation, robust design and similar. On the other hand, in CFD research aims to extend the boundaries of practical engineering use in "non-traditional" areas. Requirements of computational flexibility and code integration are contradictory: a change of coding paradigm, with object orientation, library components, equation mimicking is proposed as a way forward. This paper describes OpenFOAM, a C++ object oriented library for Computational Continuum Mechanics (CCM) developed by the author. Efficient and flexible implementation of complex physical models is achieved by mimicking the form of partial differential equation in software, with code functionality provided in library form. Open Source deployment and development model allows the user to achieve desired versatility in physical modeling without the sacrifice of complex geometry support and execution efficiency.

Nowadays, spatiotemporal data models deal with objects which can be potentially useful for wide range applications in order to describe complex objects with spatial and/or temporal facilities. However, the information needed by each application usually varies, specially in the geographic information which depends on the kind of time oriented views, as defined in the modeling phase of the spatiotemporal geographic data design. To be able to deal with such diverse needs, geographic information systems must offer features that manipulate geometric, space-dependent(i.e, thematic), and spatial relationship positions with multiple time oriented views. This paper addresses problems of the formal definition of relationships among spatiotemporal objects and their properties on geographic information systems. The geographical data are divided in two main classes : geo-objects and geo-fields, which describe discrete and continuous representations of the spatial reality. I study semantics and syntax about the temporal changes of attributes and the relationship roles on geo-objects and non-geo-objects, This result will contribute on the design of object oriented spatiotemporal data model which is distinguishied from the recent geographic information system of the homogeneously anchored spatial objects

As the scale of airborne system software increases, the use of OOT (Object-Oriented Technology) is increasing for functional expansion, efficient development, and code reuse, but the verification method for airborne object-oriented software is conducted from the perspective of the existing procedure-oriented program. The purpose of this paper was to analyze the characteristics of OOT and the vulnerabilities derived from the functional characteristics of OOT, and present a verification method applicable to each software development process (Design, Coding and Testing) to ensure the functional safety integrity of aviation software to which OOT is applied. Additionally, we analyzed the meaning of the static analysis results among the step-by-step verification measures proposed by applying LDRA, a static analysis automation tool, to PX4, an open source used to implement flight control software.

Design patterns are used to utilize well-defined design information. As using these design patterns, we can get re-use in object-oriented paradigm, decrease the time of development and improvement the quality of software. Although these design patterns are widely used among practice, most of design patterns information is manually used, inconsistent and its utilization could be very low. Because the design patterns information that a designer applies does not appear in software, it is sometimes difficult to track them. In this paper, we propose a tool support for design pattern-oriented software development. This tool supports design pattern management, software design and automatic source code generation. The design pattern management has the function for storing, managing and analyzing the existing design pattern and registering new design pattern. The software design has the function for software design with UML and automatically generate design pattern elements. By using this design information, this system can automatically generate source code. In the result to include the tracking design pattern element that is not Included In the existing CASE tools into design information, we can build the stable and efficient system that provides to analyse software, manage design pattern and automatically generate source code.
