객체지향 방법론은 캡슐화(encapsulation), 상속(inherit), 다형성(polymorphism)과 같은 개념을 이용하기 때문에 기존의 절차적 방법론과는 다른 척도가 필요하다. 본 논문에서 제안하는 척도는 객체지향 시스템의 개발 절차 가운데 분석 단계에서 추출할 수 있는 정보만을 사용하여, 클래스가 객체지향 개념에 따라 잘 구성되었는지를 측량하게 된다. 이를 위하여 본 논문에서는 클래스의 품질을 측량하기 위한 척도로 협력의 복잡도와 인터페이스 복잡도를 제안한다. 협력의 복잡도는 클래스가 잠재적으로 얼마나 복잡할 수 있는지를 측량하기 위한 것으로서 클래스가 가지는 책임의 개수를 조사하여 정의된다. 인터페이스 복잡도는 클래스와 협력 관계에 있는 다른 클래스들의 인터페이스를 조사하여 정의된다. 제안된 척도는 기존의 척도들이 가지고 있는 문제점을 해결하기 위하여 이해하기 쉬운 수학적 명세를 용하였으며, 제안된 척도에 대한 수학적 증명과 사례 연구를 통한 검증을 하였다.

본 논문에서는 객체지향 패러다임의 구조적 특성을 적용하여 만든 시소러스를 이용하여 웹 자원의 의미적 연관성을 RDF 형식으로 표현할 수 있는 RDF 문서 자동 생성기를 소개한다. 객체지향 시소러스를 RDF 형식으로 나타내기 위해 시소러스에 사용된 객체와 관계의 내용을 명세한 네임 스페이스를 정의하여 시맨틱 웹에서 메타데이타를 기술하는 표준이 되는 RDF와 RDF Schema 형식으로 매핑할 수 있다. 이러한 연구를 통해 객체지향 시소러스의 내용을 RDF 형식으로 표현함으로써 지식베이스(KnowledgeBase)라 불리는 온톨로지를 생성할 수 있으며, 구축된 온톨로지는 시맨틱 웹 상의 에이전트나 다른 어플리케이션에 응용될 수 있다.

최근 인터넷을 통한 정보 교환을 위해 XML(eXtensible Markup Language)에 대한 저장 및 검색에 대한 연구가 활발히 진행되고 있다. 본 연구에서는 객체지향형 데이터베이스를 이용하여 대량의 XML문서에 대한 저장 및 검색을 지원하는 XML 문서 저장 시스템을 설계하였다. 제안하는 데이터 모델은 XML 문서의 삽입 및 갱신이 용이하도록 분할 방식을 사용하였으며, 객체지향형 데이터베이스에서 구조정보를 추출하기 위한 새로운 모델을 제시하고 있다. XML 문서의 주된 구조정보를 갖는 엘리먼트와 에트리뷰트를 DTD별로 저장하고, 하나의 DTD를 따르는 문서 인스턴스들에 대한 관계를 리스트롤 이용하여 저장해 둠으로서 객체지향형 데이터베이스 내에서 임의의 위치에 존재하는 객체에 대한 접근을 빠르게 지원할 수 있도록 설계하였다.

The purpose of this study is to analyze the components and to verify the relationship among service orientation effort, job satisfaction, organizational commitment and turnover intention in logistics firms. A literature survey is presented; then, an empirical analysis is carried out using data from questionnaires to employees in logistics firms. The final results indicate that Service orientation effort of logistics firms is positively related to job satisfaction and organizational commitment. Moreover, service orientation effort, job satisfaction and organizational commitment are negatively related to turnover intention. Following these results, it is necessary to concentrate on enhancing the service orientation effort to increase job satisfaction and organizational commitment and decrease turnover intention.

This paper describes and constructs object-oriented analysis models using Galois-lattices that we are always studying in discrete mathematics, shows fundamental approaches to maintain the models, analyzes the construction of object-oriented analysis models through good examples. Also, we define several properties of Galois-lattices that have binary relations between class objects, propose the incremental updating algorithms that can update the Galois-lattice whenever new classes are added. This proposal shows that in case of adding new class nodes the results from simulations can implement in constant time and have linearly the incremental structures in worst cases, and in that the growth rate of lattices is proportioned to class nodes in time complexity. This results can achieve the high understandability of object-oriented analysis models and the high traceability of maintenance models. Furthermore it is possible to make more efficient performances of class reusability in advantages of object-oriented systems and support truly the class hierarchical maintenances.

This study was to analyze the effect of market orientation on service quality and business performance in the firms of private security guards. To attain the goal of the study described above paragraphs, some peoples held in Seoul were set as a collected group. Then, using the purposive sampling method, finally drew out and analyzed 235 peoples in total. The material collection device was the brochure named . The result of reliability check up was here below; Chronbach' $\alpha$=.732. To analyze materials, reliability analysis, SEM were used as statistic analysis techniques. The conclusion based on above study method and the result of material analysis are here below. First, market orientation have influence on service quality. Second, market orientation have influence on business performance. Third, service quality have influence on business performance.

The primary goal of the database design is to organize a large amount of data effectively in users and systems view point. Effective design of a database is very important for processing applications efficiently. In this paper, we discuss database design for an urban geographic information system that effectively maintains the cadastral and planimetric information. We first collect and analyze the requirements for the target urban geographic information system and then perform database design for these requirements. Our database design is based on the object-oriented approach that has rich expressive power and good reusability in comparison with the traditional relational approach. Especially, we employ the OMT, one of the most widely-used object-oriented models. We expect that our result would be helpful in building large databases for urban geographic information systems practically.

This study explored the entrepreneurial intention of university students by empirical study on them and studied the various variables, which have impact on their entrepreneurial intention. The result of examination on the impact factors of each independent variable on entrepreneurial intention was as following. There were significant relation with individual ability in individual characteristics and with safety orientation, autonomy orientation, technology orientation and business orientation in career orientation. The examination result on the impact of entrepreneurial environment on entrepreneurial intention was as following. There was significant relation between individual network and entrepreneurial policy. It was also possible to find that a student, who received entrepreneurial education as one of control variables, has higher entrepreneurial intention than a student who did not receive entrepreneurial education. Especially, business orientation was the most significant factor on entrepreneurial intention among multiple significant variables. Therefore, diverse entrepreneurial education programs should be developed and supplied so that university students can create business idea of own and reinforce the design ability related to the business.

The purpose of this study is to suggest implications for the importance of shared leadership of leaders by analyzing the influence of learning orientation and unlearning on the recognition of leader's shared leadership and employees'. The questionnaire survey was conducted on the employees who work as knowledge workers in the domestic SMEs. A total of 387 questionnaires were collected using SPSS 24.0 statistical package. The results of this study were that the relationships between a leader's shared leadership and innovation behavior, shared leadership and learning orientation, and learning orientation and innovation behavior were positive. In addition, learning orientation mediated in the relationship between shared leadership and innovation behavior, and unlearning reinforced the relationship between shared leadership and learning orientation. The implication of this study is that the employees themselves need continuous reinforcement activities for active unlearning and learning orientation in order to improve the innovation behavior of the employees. In addition, the shared leadership of leaders in employees and organization is more important.

This study analyzes, based on survey of the behavior of 288 railroad tour conductors. how deep acting and surface acting, which were both classified as emotional labor, influence customer orientation. It also analyzes the moderating effect of POS (perceived organizational support) on emotional labor and customer orientation. The following are the summarized results of the analysis. First, railroad tour conductors' deep acting has a positive influence on customer orientation. And surface acting has a negative effect on it. Second, after the moderating effect of POS has been studied, it is found that POS does not appear to have a moderating effect on customer orientation of deep acting but does appear to have a moderating effect on customer orientation of surface acting. In conclusion, this study implies that it is important, to railroad tour conductors, that organizational level support enhance customer orientation; it is also important to manage railroad tour conductors' emotions in order to enhance customer orientation.
