The purpose of this study was to analyze the effect of the consumer-brand relationship Quality (CBRQ) on the brand loyalty in the fast food restaurant in Masan, Korea. The Questionnaires were distributed to 250 students in the K University located in Masan, who were sampled by convenience-sampling method. The surveys were performed from December 6 to 14, 2004. The 246 Questionnaires were responded, and 12 unusable Questionnaires were excluded, then 234 were used for the final analysis $(response rate:\;93.7\%)$. For the statistical analysis, SPSS (12.0) was used to conduct the descriptive analysis, factor analysis, reliability analysis, Pearson correlation and multiple regression analysis. The result of this study showed that 2 constructs (satisfaction and commitment) of consumer-brand relationship Quality have significant positive effects on the brand loyalty in the fast food restaurant. It meant that as consumer-brand relationship quality becomes stronger, the customer's brand loyalty becomes greater. The differences of customer loyalty between the high and low group of self-connective attachment, satisfaction, commitment, trust and intimacy were significant. So the brand loyalty of high group of customer-brand relationship quality was significantly higher than that of low group of customer-brand relationship quality. As a conclusion, the operator in the fast food restaurant should focus on the marketing strategy to strengthen the quality of consumer-brand relationship in order to increase the brand loyalty of customers.

The purpose of this study is to analyze the astronomical thinking level of elementary, middle, and high school students using ordered multiple choice items. For this purpose, we constructed a questionnaire comprising three items about spatial thinking and system thinking. This survey was conducted and applied to 1,066 students in the 5th grade, 8th grade, and 11th grade in 12 schools located in Gangwon Province. The collected student response data were analyzed by applying inferential statistics of classical test theory and Rasch model. The results of the analysis were as follows; First, in the level of spatial thinking, students were able to grasp the spatial location and orientation of the celestial body, but were not able to convert the celestial motion of two-dimensional plane into three-dimensional plane, and it was revealed that there is no statistically significant difference in the spatial thinking of students among grade levels. Second, in the level of system thinking, students were able to identify the components and relationship between components of the celestial motion system, but could not identify the patterns of the system, and it was revealed that there was statistically significant difference among the system thinking of students in different grade levels, unlike in spatial thinking. Third, the astronomical thinking expressed in certain context (content) was very similar regardless of grade level, Through this, we could confirm the context-dependency or content-dependency of the astronomical thinking of students. It is expected that the results of this study can be used as basic data for exploring ways to enhance astronomical thinking level in school science classes.

This study set out to construct an social capital scale that could be commonly used by social welfare organizations and to apply it to examine any differences in social capital among social welfare organizations. For those purposes, the study distributed a questionnaire by mail to social welfare organizations in 15 cities and provinces across the nation and conducted latent means analysis. The major research findings were as follows. First, as a result of exploratory factor analysis and confirmatory factor analysis, the validity and reliability in measurement indicators of social capital were proved to be satisfactory level. Secondly, social capital were found to be interpreted at the organizational level through the review of levels of analysis. Meanwhile, the configural, metric, and scalar invariance of social capital scale were confirmed, which indicates that the social capital scale can be commonly applied to social welfare organizations. Finally, latent means analysis was carried out to examine differences among social welfare organizations in the subindexes of social capital including network connectivity, setting and sharing of vision, reciprocal norm, trust and cooperation, and group participation. As a result, there were significant differences among social welfare organizations in network connectivity, reciprocal norm, trust and cooperation and group participation but no statistically significant differences among them in sharing of vision, goal and core value. Those findings led to implications needed to manage of social welfare organizations.

현재 통신망 서비스는 과거의 한 지역에 국한된 서비스 수준을 넘어 전세계 지역을 대상으로 발전되고 있으며, 그에따라 통신 설비와 그 서비스의 종류도 다양화 및 고도화 되어 가고 있다. 그러나, 각 지역의 통신 노드들은 서로 다른 형태의 정보와 시스템으로 구성되어 있기 때문에 전체 통신 노드들의 통합시 발생할 수 있는 이기종 시스템간의 상호운용(interoperability) 및 관리 문제, 분산 환경하에서의 처리 문제 및 무관성(transparency) 충족문제 등을 표준화 작업을 통하여 해결해 나가고 있다. 또한, 초기의 통신망 출현 시에는 망 자체적인 특성으로 인하여 정보의 수준이 단순하였으나, 요사이 통신망은 엄청난 수의 노드 분산화, 구성 노드의 이질화 및 복잡화는 물론이고 이러한 특성을 갖는 망 자체의 빠른 진화로 인하여 망에서 다루어야 할 정보의 종류와 가지수는 천문학적으로 증가하고 있는 실정이다. 이와 같은 현실로 인하여 정보 관리 서비스 구조에 대한 연구가 꾸준히 진행되어 1988년 국제전신전화자문회(Consultative Committee for International Telegraph and Telephone: CCITT, 이하 CCITT라 함, CCITT는 현재 ITU로 개명)에서는 전체 통신망에 존재하는 통신 관련 정보를 효율적으로 관리할 수 있는 강력한 정보 제공 시스템인 전역(global) 디렉토리 서비스에 대한 국제 표준으로 X.500 시리즈를 발표하기에 이르렀으며, 계속적인 보완작업을 통하여 1992년판 표준안이 완료되었다. 이에 본 고에서는 1992년 판 X.500 디렉토리 표준에 명시된 내용 중 정보 모델링 관점의 내용들을 발췌 분석하므로써 향후 디렉토리 정보 베이스 구축시에 가이드라인으로 사용할 수 있도록 하고자 한다.

A lot of learning systems are applying self-directed learning to increase learner's learning effect. But most of this methods are hardly applied to fit the construction of learning contents considering learner's characteristics or it was processing the learning course without learner's choice. In this research, we proposed the recommendation method that can support the learning contents as calculate learner's preference contents based on learning history information when learner design the learning course. In the result, we chose test learner group and was able to know to generally increase average score of each learner after test between existing method and proposal one.
