Objective : This study sought to investigate the effects of a sensory integration intervention focusing on vestibular and proprioceptive on the spatial relations and visual-motor coordination of children with developmental disorders. Methods : Three children with developmental disabilities aged 5 to 6 years were the subjects of this study, and the ABA' design, which is one of the single subject research designs. A total of 18 sessions were conducted over a six-week period-that is, three 30-minute sessions per week. During the three baseline sessions, the children's spatial relations and visual-motor coordination were evaluated prior to the intervention. During the 12 sessions conducted in the intervention period, a vestibular and proprioception sensory integration intervention was performed, while in the final three sessions, the children's spatial relations and visual-motor coordination were again evaluated (without any further intervention Children were measured and evaluated every session after intervention using a computer cognitive rehabilitation program (CoTras-C). Moreover, the Kaufman Assessment Battery for Children and the Korean-Development Test of Visual Perception-2 were used as evaluation tools to verify the effectiveness of the intervention. Results : There were significant differences in the spatial relations and visual-motor coordination scores of the children with developmental disorders before and after the vestibular and proprioceptive sensory integration intervention. More specifically, after the intervention, all three children showed statistically significant improvements. Conclusion : The applied vestibular and proprioceptive sensory integration therapy had a significant impact on the spatial relations and visual-motor coordination of the three children with developmental disorders.

직관력은 현대와 같이 급변하는 사회에서 어떤 문제의 상황을 전체적으로 파악하거나 그 본질을 인식하는데 매우 중요하다. 특히 공간 직관력은 매일을 공간 속에서 생활하고 있는 우리에게는 더욱 소중한 교육적 대상이 된다. 공간 직관력은 눈에 보이는 구체물이나 감각적으로 받아들여진 사물을 통하여 그 배후에 있는 공간으로서 추상적, 이상적인 것을 감지할 수 있는 힘이다. 수학교육학적 관점에서 보면 공간 직관력에는 시각화(도형을 인식하는 능력, 도형을 구성하는 능력 등), 공간적 관계(도형이나 공간의 확장을 이해하는 능력 등), 공간적 방향 파악(위치를 파악하는 능력 등)을 포함한다. 본 연구에서는 이들 공간 직관력을 육성하기 위하여 초등학교 교육과정과 연계하여 적절한 학습 내용 및 방법을 고찰하고자 한다.

The cube-accumulation is a new theme included in the 7th elementary mathematics curriculum for improving children's spatial ability. One activity of the cube-accumulation is to recognize the configuration of accumulated cube given three plane figures in the directions of the above, the front and the side, respectively. The approach to this activity presented in the mathematics textbook is more or less intuitive and constructive, and difficult to some children. So we suggest an alternative, more analytic method, 'elimination method', that is eliminating unnecessary parts from $n{\times}n{\times}n$ whole cubes. This method was adopted to the 32 sixth graders, in special five applicants among them. Their responses and activities were analyzed. We confirm that we can teach the cube-accumulation by the elimination method, and some children prefer this method. 13u1 this method requires more exercises to be executed skillfully.

가상현실 시스템에서의 가장 기본적인 상호작용은 사용자가 원하는 위치와 방향으로 시야를 이동하는 네비게이션이다. 기존의 관련 연구들은 가상환경 네비게이션의 고전적인 문제인 'lost-in-cyberspace'에 대한 명확한 해결책을 제시하지 못하고 있다. 또한, 직관적이고 사용방법이 쉬운 상호작용에 대한 연구가 충분히 이루어지지 않았다. 본 논문에서는 증강현실 기반의 감각형 오브젝트를 이용한 네비게이션 인터페이스 시스템과, 사용자의 컨텍스트를 활용한 네비게이션 방법을 제안한다. 테이블의 표면에는 프로젝터를 이용한 후면 영사를 통해 가상환경의 지도와 사용자를 위한 네비게이션 정보가 보여진다. 사용자는 테이블 공간에서 카메라를 이용해 추적되는 감각형 오브젝트를 조작함으로써 가상환경을 네비게이션 할 수 있다. 또한, 사용자의 관심 지역 및 가상공간의 중요 지역 등의 컨텍스트는 사용자의 간단한 오브젝트 조작 정보와 결합되어 이동 경로 생성에 이용된다. 제안된 시스템은 본 연구실에서 제작된 Responsive Multimedia System (RMS) 의 인터페이스 시스템으로 연동되어 실험을 수행하였다. 제안된 시스템 및 네비게이션 기법은 사용자에게 전체 가상환경에 대한 인지력을 향상시키고, 직관적인 인터페이스를 제공하며, 최소한의 조작으로 만족스러운 네비게이션을 제공한다.

The purpose of this research is to find out effectiveness of geometry learning through spatial reasoning activities on mathematical problem solving ability and mathematical attitude. In order to proof this research problem, the controlled experiment was done on two groups of 6th graders in N elementary school; one group went through the geometry learning style through spatial reasoning activities, and the other group went through the general geometry learning style. As a result, the experimental group and the comparing group on mathematical problem solving ability have statistically meaningful difference. However, the experimental group and the comparing group have not statistically meaningful difference on mathematical attitude. But the mathematical attitude in the experimental group has improved clearly after all the process of experiment. With these results we came up with this conclusion. First, the geometry learning through spatial reasoning activities enhances the ability of analyzing, spatial sensibility and logical ability, which is effective in increasing the mathematical problem solving ability. Second, the geometry learning through spatial reasoning activities enhances confidence in problem solving and an interest in mathematics, which has a positive influence on the mathematical attitude.

Objective : The purpose of this study is to investigate the meaning of students' experience participating in the flipped learning based instruction in sensory integration, and to understand the demand and introspection of participants. Methods : This study used a phenomenological approach of qualitative study. The participants were 10 students in 3rd year of the occupational therapy program in K Univeristy. Data information was collected by one-to-one interview and analyzed through phenomenological research method. Results : Through the interview, 20 units of meaning, 8 central meanings, and 3 themes were drew. The information collected were analyzed into three themes; Learning Experiences in Online and Offline Courses, Request and Introspection of Learners on Flipped Learning. The result showed that online courses brought learners convenience and satisfaction with repeatable learning in every time and space the learner want. However, the learners appealed issues of communication and concentration due to the absence of face-to-face instruction by their instructor. For the offline courses, students showed interest in various practical classwork of sensory integration and changes in their attitude to actively engage in the practical classes. Conclusion : Flipped learning based instruction was effective for the sensory integration classes which require practice in terms of time securement and immersion in practice. The learners requested for adopting flipped learning based instruction to other subjects in occupational therapy curriculum, and introspected that they needed to actively engage in classes through the experience of flipped learning-based classes of sensory integration. The results of this study can be used as a basic resource when flipped learning classes are planned in occupational therapy education.

The acting of physical action of the director Kang Yang Won's plays is mostly simple and repetitive. This acting induces the audience to sensuous perception and certain corporal emotions. In addition to semiotic meaning of dialogue a stimulus is given directly to sense of the audience. Therefore, the audience participate in creating a performative space with assistance of atmosphere. So, the feedback-loop of autopoiesis is made and the emergence of meaning is experienced due to felt perception. This emergent meaning springs unexpectedly by imagination, remembrance, and association etc. and is not produced on purpose. In addition, the audience participates in the performance together by the intersection of the perception for representation and perception for presence, and is especially affected by the presence of acting of physical action. In this paper, the study of four major performances of the theatre troupe Dong performed since the 2010s confirmed not only the individuality of each performance, but also the commonality that encompasses the entire performances. This led to discovering the discrimination power of the aesthetics of theater of the director Kang Yang Won and the theatre troupe Dong.
