  • 본 논문에서는 객체 지향 소프트웨어 개발 생명주기에서 생성된 객체 모델들간의 일관성 유지를 위한 관계성 분석 도구 설계 방법을 제시한다. 이 방법에서는 객체 지향 모델의 산출물들간의 관계성을 분석하여 소프트웨어가 개발됨과 동시에 부품화 되어 저장된다. 그리고 소프트웨어 유지 보수 및 재사용이 가능한 검색 시스템으로 되어 있으며, 객체 지향 CASE 시스템의 정보 저장소 기능을 부분적으로 지원한다. 따라서 시스템 분석가 및 설계자에게 유용한 지침을 제공하고, 개발자에게 산출물들간의 일관성 검증을 쉽게 하도록 하여 소프트웨어 재사용 및 유지보수가 용이하다.

  • 본 연구는 방사선사가 인지하는 조직문화와 셀프리더십 유형을 살펴보고, 조직유효성에 영향을 미치는 관련요인을 분석하였다. 셀프리더십의 전체 평균은 5점척도에 3.35점이었,다. 셀프리더십의 자기목표설정과 조직문화의 관계지향적요인은 조직몰입과 직무만족에 모두 관련이 있었다. 조직몰입은 근무지, 조직문화의 위계지향적, 관계지향적 요인이 26.8%의 설명력으로, 직무만족은 기혼자, 셀프리더십의 자기목표 및 자기관찰, 관계지향적 조직문화 요인이 41.6%의 설명력으로 나타났다. 조직의 성과를 높일 수 있는 조직문화를 형성해 나가는 방안의 모색이 필요 할 것이다.

  • 본 연구는 재사용이 가능한 객체지향 컴포넌트의 효율적인 검색을 위해 클래스 개념 범주(CCC)를 정의하고 클래스의 상속 관계를 이용한 CCC 상속을 제안하였다. CCC의 상속은 클래스 간 상속관계를 인지한 후, 하위 클래스는 상위 클래스의 모든 CCC를 자동 상속받게 되며, 클래스 구문분석에 의해 객체지향 코드로부터 자동 인식된다. 본 연구는 모든 용어에 대한 범주를 수동으로 할당해주는 기존 방법의 단점을 극복할 수 있으며, 시소러스를 자동으로 갱신할 수 있다는 장점이 있다.

  • The purpose of this study was to identify the effect of dental hygienists' perceptions of dental organizational culture and professional identity on organizational commitment. A survey was conducted with 310 dental hygienists working in dental hospitals and dental offices. If dental hygienists experience organizational cultures as having different degrees of organizational commitment, then the type of organizational culture and commitment may be important variables in understanding and reducing the turnover rate of dental hygienists and improving workplace performance. Efforts to form a healthy and positive organizational culture may therefore be necessary. The organizational culture most recognized by the dental hygienist was hierarchical culture (3.39) and the least recognized was task-orientated culture (2.71). The professional identity of the dental hygienist was 3.75 and the organizational commitment was 2.98. Correlation analysis was conducted to investigate the relationship between dental organization culture type, professional dental hygienist identity, and organizational commitment. As a result, professional identity and organizational commitment showed positive(+) correlation with innovation oriented culture and relationship oriented culture. Among the organizational culture types, relationship-orientated culture (p<0.001) and innovation-orientated culture (p=0.006) were significant influences on organizational commitment, and professional identity did not have a significant influence. The regression model was found to be statistically appropriate (F=11.857, p<0.001) and the model explaining power was 14.9%. These results suggest that efforts to create a relationship-orientated culture and an innovation-orientated culture and to reduce the hierarchical culture can be a strategy to enhance the organizational commitment and the professional identity of dental hygienists.

  • Views are essential in providing logical data independence for database systems. Object views in object-oriented/object-relational databases have requirements quite different from those of relational databases due to support for object-oriented concepts. Although many commercial object-oriented/object-relational database systems support object views, implementation techniques have not been discussed sufficiently in the literature. In this paper, we devise a technique for implementing views in object-oriented/object-relational databases and apply it to the ODYSSEUS object-relational database system. We first analyze the requirements of object views. Next, to implement object views, we extend the existing query modification algorithm that has been proposed for implementing views in relational databases. Next, we compare the features of the proposed object view with those of object views in commercial object-relational database systems. It is shown that the proposed object view supports all object-oriented concepts such as object identifiers, inheritance, methods, and composite objects, while existing object views support part of them. Last, we propose detailed techniques for implementing the extended query modification algorithm in the ODYSSEUS object-relational database system.

Those components are, for example, social, psychological, economic and special treatment benefits on long-term orientation of relationship. Also, ultimately, this study aims to suggest marketing strategies and relevant implications for airlines. In conclusion, psychological and special treatment benefits were found to have influence on long-term orientation of relationship.

  • Many researches and validations for the complexity metrics of the object-oriented systems have been studied. Most of them are aimed for the measurement of the partial aspects of the systems, for example, the coupling between objects, the complexity of inheritance structures, the cohesion of methods, and so on. But the software practitioners want to measure the complexity of overall system, not partial. We studied the complexity of the overall structures of object-oriented systems by analyzing the class diagram of UML. The class diagram is composed of classes and their relations. There are three kinds of relations, association, generalization, and aggregation, which are making the structure of object-oriented systems to be difficult to understand. We proposed a heuristic metric to measure the complexity of object-oriented systems by putting together the three kinds of the relations. Tn analyze the complexity of the structure of a object-oriented system for the maintainability of the system, we measured the degree of understandability of it, the reverse engineering time to draw a class diagram from the source codes, and the number of errors in the diagram. The results of this experiment shows that our proposed metric has a considerable relationship with the complexity of object-oriented systems. The metric will be helpful to the software developers for their designing tasks by evaluating the complexity of the structures of object-oriented systems and redesigning tasks , of them for the future maintainability.
