본 논문에서는 UML을 기반으로 한 객체지향 시스템 개발에서 발생하는 멀티미디어 산출물들을 저장, 관리하기 위한 객체 저장소의 산출물 관리 기법을 제시하였다. 객체 관리 기능 모듈은 상용 객체 관계 DBMS인 IUS를 이용하여 구현하였다. 산출물 객체의 표현 및 데이터의 공유를 위해 UML 다이아그램 산출물을 XML 문서 형태로 표현하고, eXcelon XML 데이터 서버를 이용하여 XML 문서처리 시스템을 구현하였다. 산출물 객체의 관계 관리 기법과 UML 다이아그램에 대한 XML 문서화 기법은 UML을 기반으로 하는 CASE 도구의 개발에 활용될 수 있다.

This paper explores whether there is significant difference or not in the empowerment of social workers, e.g. individual's business-oriented, business relationship, and compensation system, according to the organizational culture types of social welfare facilities such as community culture, development culture, hierarchical culture, and reasonableness culture. By means of survey, this research targeted the social workers of social welfare facilities. The culture types that social workers recognize are sorted into community culture, development culture, hierarchy culture, and reasonableness culture according to the division of Kimberly and Quinn (1984). This study shows that there is significant difference in individual’s business-oriented, business relationship, and compensation system according to the type of organization culture.

This study analyzes the impact of followership on the relationship between leadership and organizational performance, and also which type of leadership-followership combination brings out higher performance in the local government of South Korea. Using the survey data conducted to the civil servants in Kyounggi-do, Pyeongtaek-shi and Dongdoochun-shi, this study analyzes the mediating and moderating effects of followership. The results show followers do affect the organizational performance in the local government and the mediating effects exist in all types of followership. These results emphasize the fact that the role of followers should be investigated as a main factor determining organization performance along with leadership. Moreover, this study found out the more similar the set of values between leaders and followers, the higher performance an administrative organization can get. This implies the necessity of more investigation of the interaction between leaders and followers in the study of organizational performance.

The data model is a system model which abstracts the spatial and nonspatial fea¬tures of the real world. A system defines through its data model a framework for the inner rep¬resentation of and connections with the outside world. The spatial query language is one of the most efficent framework for defining connection with outside world in the GIS. Existing GIS uses a spatial data model based on relational data model. Therefore, it has some difficulties in data abstraction and representing complex objects through inheritance. In this paper, we pro-pose an object oriented data model-Topological Object Model(TOM). TOM combines object model in ODMG and the planer topological object. Based on this model, we present an object-oriented spatial query language-OQL/Geo. OQL/Geo extends OQL in ODMG and represents TOM effectively. It also provides several operators such as geometric, topological and visible ope-rators. Moreover, it represents with diverse flexivility the request for complex spatial analysis and presentation of query results.

The purpose of this study is to depict statistically and exploratively the interrelationship among learning orientation, environmental turbulence, and performance in the railway public organizations. To attain this purpose, a questionnaire was provided based on literature survey, and 616 respondent's data received was tested for its validity and reliability. And then, simple and vertical regression analysis were performed. The main findings are as follows: First, learning orientation has a relatively positive effects on performance. Second, environmental turbulence shows a partial moderating effects on the relationship between learning orientation and performance. These findings suggest that learning orientation do exist as an important organizational cultural dimension that contributes to the acquisition of sustainable competitive advantage, and some restrictive factors of public organizations seem to inevitably disrupt the intrinsic necessity of learning in the railway organizations.

This study is a descriptive research study to confirm the mediating effect of job engagement on the relationship between the nursing organizational culture and the quality of nursing service perceived by nurses. The research subjects and data were collected from June 1 to June 7, 2022, and 215 nurses working at hospital-level or higher medical institutions recruited through the online community for nurses. As a result of the study, Relation orientated culture(Z=3.88, p<.001) and Task orientated culture(Z=3.16, p=.001) affected the quality of nursing service, and it was found that job engagement fully mediating effect. Hierarchical orientated culture (Z=2.39, p=.017) affected the quality of nursing service, and it was found that job engagement had a partial mediating effect. Therefore, in order to improve the quality of nursing services, it is necessary and to promote work engagement by forming a culture to establish a trust relationship among members based on the order and procedure for safety in nursing sites that require rapid and accurate response in emergency situations and performing tasks efficiently to achieve organizational goals.

Korean government has developed the 1st version of the National ITS Architecture in 1999 and utilized it as the framework for ITS planning, design, and standardization. The National Architecture now needs to be revised to accommodate environmental changes in ITS market and advancement of ITS core technologies. This study evaluates the current version of the architecture and suggests the directions for revision for a new national ITS architecture. The two most popular methodologies for architecture development-the process-oriented approach and the object-oriented approach-were reviewed, and the process-oriented approach was selected for new architecture development. The concept of the national architecture was then newly defined based on evaluation of the existing architecture. The new National ITS Architecture is suggested to be composed of ITS user services, logical architecture, physical architecture, and project architecture. This study must be followed by actual architecture development efforts and supporting policy actions for successful deployment of the new National ITS Architecture.

To sustain successful relations with its customers, an internet business enterprise has to understand precisely the difference between customers' behaviour and their purchasing behaviour pattern on its customer basis. For this purpose, I closely looked into what difference there was between a leading variable which had an effect on internet customer long-term orientation and a special variable depending on period of transactions To prove this research, I analyzed collected data in which customers had experienced in shopping at internet shopping mall and discussed strategic current issues about its analytic results.

This article aims to suggest a principle frame and direction for the development of the character education program using Maumgram. Maumgram is said to clearly illustrate step-by-step structures of character education, for which the human mind is classified as four types(indulged type, rage-type, competition type, selfishness type) on the basis of the existing analytical psychology and Yogacara Thought. The design of the mind type program is composed of three steps. The first step is the 'discovery' step to awaken the cause of self-consciousness through observation, and the second is the 'conversion' step. Learning process to control the negative desires in a positive desire, and the third is the 'relationship'-oriented step to promote a sense of community with other people.

Using object relationship table, this study proposes an efficient indexing technique for accessing both aggregation and inheritance hierarchies in object- oriented databases. This indexing technique uses the information on the aggregation and inheritance relationship between classes and the information on referencing instances as meta data. As a result, the technique makes it possible to effectively evaluates various queries navigating between tables. The study compares the proposed technique with the existing indexing techniques and discusses its useful- ness. It also provides the result of simulating its performance in terms of storage and retrieval cost.
