The purpose of this study is to examine the effects of different group incentive type on performance under two types of interdependence in a task structure. One hundred twenty college and graduate students were recruited and asked to perform group typing task. Each typing groups organized three members. Participants were randomly assigned to one of four experimental conditions: equally-distributed incentive and differentially-distributed under two different task interdependence. In this study, the dependent variable was the number of correctly typed characters. We found the significant interaction effects between group incentive type and task interdependence. Specifically, under interdependent task, the work performance of participants in equally-distributed group incentive condition was higher than the performance in differentially-distributed group incentive condition.

In this paper, I pose a problem for Hitchcock's arguments for two concepts of effects that are intended to explicate double causal effects, and put forth a theory that is intended not just to meet the problem but also to accommodate Hitchcock's theory and Eells' theory both. First, I introduce an example of dual causal effects, and examine the accounts of Otte(1985) and Eells(1987) on how to explicate the dual effects. I show that their accounts of the dual effects help us understand the problem of dual effects and see how different it is for Cartwright(1979, 1989, 1995), Eells(1991, 1995), and Hitchcock(2001a) to meet the problem. Second, I introduce two concepts of effects on Hitchcock(2001a), that is, net effect and component effect that are allegedly analogous to two effects of structural equation model. Third, I reveal the significance of homogeneous subpopulation and causal interaction regarding the problem of dual effects while examining Cartwright's theory and Elles' theory. Fourth, I critically examine the two concepts of effects on Hitchcock and argue against Hitchcock's criticism of Eells' theory. Fifth, I take a moderator variable of structural equation model and a moderator effect into the probabilistic theory of causality, and formally generalize causal interaction due to the dual effects in terms of disjunctive relation and counterfactual conditionals. I expect my account of disjunctive relation and counterfactual conditionals to contribute not just to several problems the received theories of causal modelling confront but also to the structural equation models many people exploit as a promising statistical methodology.

자기설명이 학습을 촉진시키려면 무엇을 설명해야 하는지 판단해야 하고, 그에 대해 적절한 설명을 산출해내어야 한다. 본 연구에서는 촉진자극(propmpt)를 제공해서 무엇을 설명해야 하는지에 대해 도움을 주면 자기설명 효과가 얻어지는지 알아보았다. 또한 자기설명과 촉진 자극의 효과가 학습자의 인지욕구(need for cognition)와 상호작용하는지 알아보기 위해 인지욕구 수준을 상하로 나누어 3 요인 실험을 실시하였다. 촉진자극과 자기설명의 효과는 과제와 학습자의 인지욕구 수준에 따라 다르게 나타났다. 기억검사에서는 인지욕구가 낮은 학습자에게서만, 자기설명의 효과와 촉진자극의 효과가 관찰되었다. 반면에 이해검사에서는 인지욕구의주효과가 유의하였고, 3 요인상호작용 효과가 경향을 보였다. 즉 촉진 자극을 제공하는 것은 인지욕구가 높은 학습자에게서만 학습을 향상시켰다. 이 결과는 인지부하가 학습에 영향을 미치는 것으로 해석되었다.

The purpose of this study is to review the relationship between transformational leadership(charisma, individual consideration, intellectual stimulation, inspiration) and knowledge management, and the moderating effect of social(trust and interaction) in small business. In order to verify and achieve the purposes mentioned above, questionnaire data are gathered and analysed from 311 subjects in Kangwon-do province. Multiple regression and multiple hierarchical regression analysis were applied to test these hypotheses: 1) the relationship between transformational leadership and knowledge management, 2) the moderating effect of trust on the relationship between transformational leadership and knowledge management, 3) the moderating effect of interaction on the relationship between transformational leadership and knowledge management. Empirical survey's findings are as follows; First, individual consideration and inspiration leadership appeared to be positively related with all knowledge management(knowledge creation, transfer, application). Second, charisma was verified to be positively related with knowledge creation only. Third, charisma and inspirational leaderships were more positively with knowledge creation in higher trust group than in lower trust group. Fourth, intellectual stimulation and inspirational leaderships were more positively with knowledge creation in higher interaction group than in lower interaction group. Fifth, individual consideration was more positively with knowledge application in higher interaction group than in lower interaction group.

현재 대부분의 데스크탑 시스템에서 사용자는 단지 하나의 마우스를 사용해서 컴퓨터와 상호작용을 하고 있다. 본 논문에서는 각각의 손으로 동시에 두 개의 마우스들을 사용할 때, 작업 성능에 대한 효과를 살펴보고자 한다. 본 논문에서의 실험에서는 데스크탑 환경에 기반한 간단한 게임 (날아오는 총알 피하기와 잡기)에서 세 개의 독립 변수들로 한 손 또는 양 손 사용 여부, 주위 상황(총알)의 변화 속도, 그리고 두 커서(캐릭터)들간의 거리 차이를 사용하고, 종속 변수로 사용자의 작업 성능(부딪친 총알 개수)을 측정하였다. 실험 결과에 의하면, 두 커서 (또는 두 캐릭터)와의 동시 상호작용이 필요할 때 한 손보다는 양 손을 사용할 때의 작업 성능이 통계적으로 유의하게 좋았고, 두 커서 사이에 거리가 멀수록, 그리고 총알의 속도가 느릴수록 작업 성능은 유의하게 좋았다. 독립 변수들 사이에는 서로 유의한 교호작용이 나타나지 않았는데, 이것은 작업 성능에 대한 양손의 효과가 다른 독립 변수들의 각 레벨과는 상관이 없었다는 것을 의미한다.

방사선들 중에서 감마선은 우리의 몸 속을 깊숙이 침투할 수 있다. 그런 감마선이 우리 몸을 투과할 때, 체세표를 이룬 원자들의 궤도전자들과 충돌하면서 소멸된다. 우리는 그런 현상들을 물질과의 상호작용 이라 부른다. 방사선과 물질과의 상호작용은 원자의 단위에서 일어난다. 감마선이 물질과의 상호작용들은 물리적으로는 광전자 산란 효과, 컴프턴 산란 효과 그리고 전자쌍 생성효과 등으로 구분하여 설명된다. 방사선이 우리의 몸 속에서 체세포의 원자와 충돌하여 생기는 자유전자들은 몸 속에 남게 되고, 그들은 몸 속을 상당 기간 동안 배회하면서 인체의 생명 현상을 유지시킬 생화학 작용의 기능들을 약화시키기도 하고, 악성인 암세포들을 만들어내기도 하므로 건강 유지에 불리하게 작용한다. 따라서 감마선에 쪼여 생긴 자유전자들은 우리의 정상적인 건강 조건들을 해치는 주된 요소가 된다.

This study examined the effect of an interactive instrument playing program on the social interaction of adults with autism spectrum disorder (ASD). A single subject design with multiple baselines across participants was applied, and three adults with severe ASD in their late 20s living at a group home participated in this study. Participants received a total of 25 group sessions. During the intervention, participants engaged in structured instrument playing in which initiation and response to socially interactive behaviors were musically cued, and target behaviors were reinforced in the musical environment. At pre- and posttest, the frequency of initiation of and responding to social interaction behaviors were recorded and analyzed. The results of this study showed that the frequency of both initiation of, and response to, social interaction increased for all participants during the intervention phase, compared to the baseline phase. This result demonstrates that interactive instrument playing increased social behaviors of adults with ASD. It also shows that musically delivered social information can facilitate adults with ASD understanding the intention of social partners in social contexts and motivate this population to engage in social interaction.

The purpose of this study was to investigate the effects of science inquiry experiments emphasizing social interaction on the development of process skills of the students. The social interactions by cognitive level of the students were also analyzed. For this study, 197 8th grade students were sampled. They were divided into an experimental group and a control group. During four-month period, the experimental group received science inquiry experiments treatment emphasizing social interactions while the control group received traditional treatment. Not only science inquiry ability pretest-posttest, but also multiple data collection method such as a questionnaire, class observation, and audio/video recording were used in collecting the data. According to the results of this study, it was found that the mean score of the experimental group was significantly higher than that of the control group at 0.05 level. It was also found that the students of high cognitive level led the peers and participated in the class discussion actively with the teacher while the students of low cognitive level followed the students of high cognitive level and showed inactive interaction with the teacher. Analysis of the students' perceptions on inquiry experiments showed that students participated in discussion actively in the class as these experiments gave an opportunity for them to discuss and were able to solve the problems with peers' help through discussion.
