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, 1 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 tan use video information more efficiently by me variation.

The concepts of class, inheritance and information hicing and so on provide the great strengthes of object-oriented languages, but they also introduce diffculties in porfram analysis and understanding. Particulary, it is move difficult to umderstand the dyamic aspects than the static ones of object-oriented programs. The dyamicaspects can be understood by recognizing the event's reciprocal action among the classes. In this paper, it will be supplied to the reprecentation of event abstraction which is useful for understanding the object-oriented programs.And the clustering concept with the events will be applied to abstract the events. By clustering the events, user can get the information about function of the classes and the reteival of the class library.

Object-Oriented design method decomposes the program into object that establish the relationship between objects. It is the technique of object centered decomposition unlike function oriented legacy system. Since existing Object- Oriented design method doesn't fully explain of the design method of module and decomposition, and need to implement the Object-Oriented software as a total system init. It has many problems that whole object design method and application programs should be analyzed for the understanding an Object-Oriented software component. Therefore, this study provides a procedure for Object-Oriented module design and criteria of decomposition to practically support the complex and large system development. Futhermore, it shows a consistency between design model and implementation through a case study applying these module decomposition criteria to the real system.

스키마 변화처리시 기존의 스키마와 새로운 스키마의 관계는 대부분의 경우 서로 공통적으로 가지는 부분들과 그렇지 않은 부분들로 나눌 수 있다. 새로운 스키마는 서로 다른 부분의 구조에 대한 내용만을 기존의 구조에 추가하면 될 것이다. 이러한 성질을 객체지향 개념을 이용하여 표현함으로써 스키마의 변화 관리를 더욱 효율적으로 하는 방법을 제시하고 시스템을 설계했다. 본 연구에서 정의된 스키마 구조는 atomic type들로 이루어진 클래스들로 구성되어 있어서 변경된 내용은 스키마 전체의 변경을 요구하지 않고 이러한 타입이나 클래스의 변경에 의해서 이루어져 스키마 버젼의 관리가 용이하며 효율적이다.

컴퓨팅 환경의 주류가 종래의 클라이언트/서버 아키텍처로 부터 Web베이스의 컴퓨팅 아키텍처로 급속하게 이동하는 중에 있고, 객체 지향 데이터베이스 관리 시스템(ODBMS)에 대한 관심도 계속 증가되고 있다. 그러나 Web 콘텐트를 저장 보관하는데 있어서 ODBMS의 표면적인 장점은 이해할 수 있어도, 여전히 그 기술 및 구조적인 우위성을 이해할 수 없다. ODBMS에 대한 독자의 이해를 더욱 깊게 하기 위해, 그 구체적인 구조, 짜임새에 관해서 살펴 봤다.

본 논문은 기존의 객체지향 방식으로 작성된 프로그램에서 독립(isolated) 컴포넌트를 추출하기 위한 방법을 제안한다. 독립 컴포넌트는 별도의 컴포넌트가 필요 없이 독자적으로 이용 가능한 컴포넌트를 말한다. 기존 프로그램에서 추출되는 독립 컴포넌트는 다른 응용프로그램 개발에 쉽게 사용될 수 있다. 본 논문에서 제시하는 추출 방법은 기존의 객체지향 프로그램을 분석하여 클래스 정보를 추출하고, 클래스 간의 의존 관계를 검사하여 상호의존성이 낮고 범용성이 높은 글래스 모듈을 선택하는 것이다. 대상 모듈의 범용성은 프로그램내에서 얼마나 많이 사공되는 가로 정의된다. 본 논문에서 제시하는 방법을 사용하여 컴포넌트를 자동으로 추출하는 시스템을 구축하고자 한다.

In order to verify the effect of job-esteem attitude on the empowerment of social service workers on service orientation, this study conducted a questionnaire survey on manpower providing local autonomous social service investment projects in Chungcheongbuk-do through analyzing 329 copies of data. The main research results show that, work performance relationship and personal work orientation have a significant effect on job esteem among the sub-factors of empowerment, it was found that the work environment control had a significant effect on all of the service-oriented sub-factors (trust-oriented, sincerity-oriented, and type-oriented). In addition, personal work-oriented empowerment was found to have a significant effect on sincerity-oriented and type-oriented among the service-oriented sub-factors, and it was confirmed that the empowerment of social service workers had a positive effect on service orientation through employee appreciation as a medium. It was confirmed that job-esteem, which is a mediator, affects sincerity and type orientation, which are sub-variables of service orientation. In order to improve the service orientation of social service workers, it is necessary to develop a manual for a clear understanding of their work and to provide continuous and practical maintenance education so workers can develop their own abilities.

The relational data model is based on mathematical concept of relations and is well formulated, and so there have been numerous practical applications and studies. However, it is not suitable for representing a complex hierarchical structure, which is the characteristic of most geographical objects. On the other hand, the object-oriented data model can naturally represent a complex hierarchical structure, but there is a difficulty in sharing data with the relational data model which is currently used by most commercial GIS users. Also it has no standard query language with standardized format. In this paper, we propose an Object Grouping based on RDBMS to use data from a traditional relational data model while supporting various concepts of the object-oriented data model, and we applied this data model to design a GIS.

In recent studies, there has been much interest in knowledge sharing between the company and customer. Yet, there is little empirical work on the impact of the factors on CRM performances. The purpose of this study is empirically analyzing the effects of organizational factors of knowledge management, CRM system factors, and trust on CRM performances. The findings indicate that 3 factors (knowledge-oriented organizational culture/characteristic, technical systems, trust) are significantly related to CRM performances. However, the relationships between other factors (knowledge-oriented leadership, knowledge-oriented strategy, education & reward) and CRM performances are not significant.

Conventional switching systems have been using flat file systems or relational database systems to deal with their operational data. However, newly emerged requirements for advanced switching systems make relational database systems no longer proper solutions. This paper defines object-oriented interfaces that effectively incorporate data characteristics of switching systems. In addition, it exemplifies how the method works on an actual database systems for the TDX-10 switching system.
