  • 자기베어링 시스템은 액츄에이터, 센서, 제어기, 전류앰프 등으로 구성되어 있으며 시스템의 신뢰도는 각 구성 요소의 신뢰도와 구성요소의 상호 작용에 의해 결정된다. 자기 베어링 기술이 현재 보다 많은 분야에 적용되기 위해서는 신뢰도의 향상이 필수적이다. 본 논문에서는 자기베어링에서 사용되는 센서 중 일부가 작동하지 않더라도 시스템이 정상적으로 작동하는 센서 고장 허용 자기 베어링 시스템을 기술하였다.(중략)

  • This study examined the difference of self-determinative motivations of non-handicapped students about inclusive physical activity according to the social demographic characteristics. And this study also researched the influence of self-determinative motivation of non-handicapped student about the inclusive physical activity to interaction with handicapped student. In order to achieve the object of the study, the data collected from 674 students in included the intellectually handicapped students and inclusive physical activity. As a measuring tool, Choi (2008) and Lee (2006) questionnaire. Data was used SPSS 21.0, and the exploratory factor analysis, reliability verification, difference verification, and simple regression analysis were performed. The results are as follows. First, in terms of the data analysis of self-determinative motivation based on demographic characteristics (sex, grade, friend with disabilities, experiencing duration of inclusive physical activities), sex, friend with disabilities, experiencing duration of inclusive physical activities displayed statistically significant difference self-determinative motivation. Second, in terms of the effects of students with non disabilities self-determinative motivation on towards interaction of students with disabilities, motivation, external regulation, introjected regulation, identified regulation and intrinsic motivation among the sub-factors of self-determinative motivation affected significantly on interaction with students with disabilities.

  • Dispersed nickel particles on Spherocarb were prepared at 540$^{\circ}C$ in various reaction atmosphere. Magnetic properties of these samples were determined, and results were compared with those of unsupported and MgO supported nickel particles. It was shown that nickel react primarily with carbon regardless of reducing atmosphere. In addition, apparent possibility of nickel-carbon interaction was discussed.

  • With progress of informationalization, education has been transformed from traditional uni-direction education to bi-directional and consumer-oriented education, which is performed by learner's self study and interactive education of multiple dimension between a learner and contents, between a learner and a teacher, and between a learner and a learner irrespective of space-time. According to this trend, a new education method has been required. Therefore, in this paper, we will propose real-time consumer-oriented distance education system of making interaction maximum using WBI. In this system, a learner can participate in an individual study case by multiple interaction with a learner's designing and plaining study, and also participate in group study case by way of discussion and conversation among participants.

  • 최근 대형 디스플레이 및 웨어러블 컴퓨터의 등장과 함께 키보드와 마우스를 사용하는 일반 데스크탑 환경에서 벗어난 컴퓨터와의 자연스러운 상호 작용 연구가 활발히 진행되고 있다. 본 논문에서는 스크린 정면에 놓인 프로젝터가 스크린과 그 위에 놓인 사용자의 손 위에 화면을 투영할 때 PC 카메라로 입력된 프레임 속에서 손의 영역을 인식하여 컴퓨터와 상호작용하게 하고자 한다. 이 경우에 투영된 빛이 사용자의 손 위에도 합쳐짐으로 인하여 피부의 고유색이 사라진다. 또한, 투영되는 화면이 사용자와 컴퓨터의 상호 작용에 따라 추정할 수 없이 변함에 따른 적응적 인식 방법이 필요하다. 따라서, 본 논문에서는 손을 인식하기에 앞서 스크린에 투영될 원본 이미지에 대해 칼라 보정을 수행하여 추정되는 카메라 입력 프레임을 생성한다. 이를 위해 우선 백색 영상을 투영하여 프레임 내의 자기 오차 맵을 생성한 후 R,G,B 채널 별로 원본 값에 대한 카메라 반응 값들을 룩업 테이블에 저장한다. 이를 통해 원본 이미지에 대해 칼라보정을 수행하고, 생성된 카메라 추정 프레임과 실제 카메라로 입력된 프레임 간 자기 성분을 비교하여 손 영역을 검출한다. 실험 결과, 주변의 조명 상태나 프로젝터 및 카메라의 위치에 관계없이 안정적인 인식 결과를 보였다.

  • This study tests the effects of differential association, definitions, differential reinforcement and imitation from social learning theory in the explanation of university students' crimes in social network services. In addition, this study tests the interaction effects between social learning factors and other factors such as low self-control, subcultural environment, and crime opportunity for the integrated approach. Using data from 486 university students in Seoul, results show that both definition and imitation have significant influences on crimes, even though differential association and differential reinforcement factors have no significant influences on crimes in social network services. Results also reveal that there are significant interaction effects between definition and subcultural environment, which meana that definition has a strong effect on crimes in high subcultural environment. In addition, it is found that reinforcement has also a strong effect on crimes in high crime opportunity and that interaction effect between imitation and low self-control is significant, which means that imitation has a strong effect on crimes in low self-control students.

  • The purpose of this research is to scrutinize what are characteristics of client-identified significant events and interactional process in Gestalt therapy using the therapeutic media. The subjects of the study were 4 participants. To this purpose, a audio-taped session and a intensive interview were conducted to examine. The collected data for this study were analyzed by Comprehensive Process Analysis. The audio-taped session and interview data were first transcribed and then analyzed for client-identified significant events. A total of 74 pairs of conversations were analyzed to derive the interactional process within the significant event case. In conclusion, it was found that the interactional process of significant events in the Gestalt therapy contributed to the change of the client by interacting with the therapeutic media. 5 major themes of interaction with the therapeutic madia appeared. The 5 major themes are allowance, identification, recognition, acceptance and prospective. Finally, the significance and limitations of the study were clarified and suggested for further study.

  • This study attempts to discuss holistic information in order to identify the characteristics of interactions using a graphing calculator. The use of a graphing calculator was divided into three stages: Visual, Analytical, and Self-regulated. The last stage can be called the Self-regulated instrument stage, because this last stage, the use of the calculator, is generally characterized as students actively controlling their ongoing efforts through self-regulating. The accomplishments of the operation can be divided into three levels: Immature, Maturing, and finally, Mature level. First, the characteristics of the Leading Statements were investigated to figure out who has the main role in cooperative learning. This study can support the previous study, which showed that computers could help improve the self-esteem of low-level students. Second, the point of transformation is referred to as the Turning Point. Several functions were observed in the Turning Point: student, instrument, and teacher. Third, when the students convert-sations reach a lull in class and then resume due to certain primary factors without the teachers intervention, this is a case of what is referred to as Structuralization. And last, in this study, the graphing calculator can be used as an auxiliary stimulus to help students control their stress and their attitudes, which in turn can also improve students social interaction.
