이질적 데이터베이스간의 상호연동을 위해서 데이터의 구조를 파악하고 유용한 데이터를 선택하는 일은 매우 어렵고 많은 작업시간이 요구된다. XML을 이용하여 이질적 데이터베이스간의 데이터 교환을 위한 기존 연구가 진행된바 있으나 DTD를 통한 사상이 지원되지 않는 등 미흡한 점이 있다. 본 논문에서는 데이터베이스간의 이질적 상호연동을 효과적으로 수행하는 시스템을 설계한다. 시스템은 원시와 목표 데이터베이스로부터 추출한 스키마 그래프간의 사용자에 의한 사상을 기반으로 원시 데이터베이스를 목표 데이터베이스로의 상호연동을 효과적으로 지원한다. 본 논문에서는 시스템에 의한 이질적 데이터베이스간의 상호연동을 예를 통해서 보여준다.

This study aims to discover the mediating effect of Self-Encouragement and Self-Discouragement on the Relationships between Fear of Negative Evaluation and Social Interaction Anxiety. A questionnaire was conducted on 319 university students and the data was analyzed with Pearson's correlation and regression. As a result, there was a positive correlation between Fear of Negative Evaluation and Social Interaction Anxiety. Also, Fear of Negative Evaluation and Social Interaction Anxiety were positively correlated with Self-Discouragement and negatively correlated with Self-Encouragement. Next, multiple regression showed that Self-Discouragement has a perfect mediating effect and Self-Encouragement has a partial mediating effect on the Relationship between Fear of Negative Evaluation and Social Interaction Anxiety. These results imply that counselee with Social Interaction Anxiety can be treated effectively by promoting self-encouragement.

The purpose of this study is to explore what are the interactive factors of synchronous online education in university and identify the level of interaction. This study used mixed research method. As a result of the interaction level, it was recognized that face-to-face education could be more interactive than synchronous online education. Synchronous online education could have better interactive between instructor and learner, and among learners than asynchronous online education. Factors which influencing the interaction were as follows: small group activities and scaffolding, diversification of communication channels and integration of learner's question in learning content. Detrimental elements were distance felt between instructor and learners, low intimacy among learners, content-focused lecture, restrictions on non-verbal communication, unstable systems and misusing microphones. The necessary factors to promote interaction are planning interactive class activities, etc. Based on the results, it was to suggest what kinds of efforts are needed to make interaction more effective in terms of teaching and learning method & activity, tool & system, and environment.

As diversity has getting its significance, recent research on diversity has moved the focus from direct effects of diversity on performance to moderating effects between the two. In this paper, I analyzed the moderating effects of the innovative problem solving style and three types of interdependence (i.e., task, goal and outcome) on the relationship between diversity and performance. Empirical results using 75 project teams of R&D institute showed that the innovative problem solving style positively strengthened the effect of diversity on performance. All three types of interdependence also amplified the relationship between diversity and performance. I addressed theoretical and practical implications, and future research directions.

There are many studies which reveal most of the accidents are related to pilot errors. Looking at each phase of flight, the accidents which occurred at the segments of take-off and landing consist of 70%, cause these phases need precise cooperations between pilots and ATC specialists to make sure every instructions understood and instruments to be normal. Therefore, the accidents of these phases leave great regrets and the price was enormous to people and equipments. Until now, most of the studies investigate the accident itself and very few show the relationships between pilots and air traffic controllers. This study analyzes the inter-dependence, mutual trust, dependability and satisfaction between them who play an important parts in flight. Based upon the findings, the impacts of relationships between them to aviation safety could be explained. As for the results, the inter-dependence, mutual trust, dependability and satisfaction are relatively high but the standpoint is little bit different for each of them. These findings suggest that the improvements of relationships between them need more effort than that of the present to ensure the aviation safety and efficient flights.

The purpose of this study was to investigate how children's temperament and relationships with teachers affect their peer interaction. For this purpose, two surveys were conducted on mothers and teachers of 326 four- and five-year-old children attending four kindergartens in Gyeonggi Province. The data were analyzed by using PASW 18.0 to carry out hierarchical regression and post hocanalyses. The results showed that closeness to teachers moderated the effects of children's emotionality on their positive peer interaction. On the other hand, children's temperaments including emotionality and activity, and their relationship with teachers were directly influential on their negative peer interaction; no interaction effect was found between their temperament and relationships with teachers. It was concluded that the quality of teacher-child relationships could promote children's positive peer interaction while it could also reduce their negative interaction with peers. However, the temperament of children played limited roles in their negative peer interaction.

실증적인 연구들에 의하면 고객회사(client firms)와 서비스 제공업자(vendor) 간의 파트너십의 질과 범위가 정보시스템 아웃소싱의 성공적인 구현에 결정적인 역할을 하는 것으로 알려졌다. 본 연구는 이러한 정보시스템 아웃소싱 구현에 있어서 파트너십의 역할을 좀 더 심층적으로 분석하려는 노력의 일환이다. 본 연구에서의 기본 명제는 파트너십 특성들의 아웃소싱 구현에의 효과는 아웃소싱 업무의 특성(task characteristics)과 같은 상황적 요인에 의해 영향을 받을 수 있다는 것이다. 구체적으로 본 연구에서는 자산특이성(asset specificity)과 파트너십 특성간의 상호효과(interaction effect)에 중점을 두고 조사를 하게되는데, 파트너십은 관계적거래 특성(relational exchange characteristics)에 의해 구체화되었다. 207개의 미국 회사의 아웃소싱 관계를 대상으로 한 설문조사를 기반으로 한 결과에 의하면, 전반적으로 비관계적거래(discrete exchange)보다 관계적거래에 기반을 두고 아웃소싱 관계를 운영하는 것이 아웃소싱의 성공적 구현을 위하여 필수적인 것으로 보인다. 한편 상호효과를 조사하기 위해서는 MRA와 하위그룹분석(subgroup analysis)을 시행하였는데, 자산특이성과 일부 관계적거래 특성들간에 상호효과가 유의성이 있음을 발견하였다. 발견된 상호효과를 근거로 상황 변수를 고려하지 않은 연구 결과 중 확실하지 않은 결과(inconclusive results)에 대한 해석을 시도하였다.

This study investigated the relationships of preschool children's interactive peer play, stimulated home environment, and mother-child interaction. A total of 255 children were selected in this study. Data were analyzed with Pearson correlations and covariance structural analysis by using SPSS and AMOS, a statistical program for structural equation modeling. The major findings of this study were as follows: First, interactive peer play was associated with stimulated home environment and mother-child interaction. Second, the results confirmed the pathway from stimulated home environment via mother-child interaction to interactive peer play showing a significantly good model fit. The paths from stimulated home environment to children's interactive peer play were mediated by mother-child interaction.
