본 논문에서는 영상 처리 및 컴퓨터 비전 분야의 기술을 마이크로 소프트 사의 키넥트에 적용하여 효과적인 체감형 학습을 위한 콘텐츠를 구성하고자 한다. 일반적으로 사람들이 많이 알고 있는 손 그림자 놀이를 응용하여 참여자들의 움직임을 통해 인터랙션을 발생시킬 수 있도록 하였고, 깊이정보맵으로부터 카메라에서 가장 가까운 거리에 있는 영역을 검출하기 위해 Meanshift segmentation(평균이동분할) 알고리즘을 적용 시켰다. 본 시스템의 체감형 콘텐츠는 문화 콘텐츠의 한 종류로서 이의 확장된 버전이 여러 분야에서 많은 활용이 될 것을 기대한다.

이 연구는 대학생 시기 건강관리의 중요성을 인식하고, 대학생 집단에 초점을 맞추어 건강 관련 스마트폰 어플리케이션 활용에 영향을 주는 요인과 영향 정도에 대해 조사하고자 한다. 연구모형은 Technology Acceptance Model을 바탕으로 하여 정보보안, 놀이성, eHealth 지식, 기술장애가 인지된 유용성과 인지된 사용 용이성에 영향을 미치고, 이것이 실제 사용 의도에 어떠한 영향을 미치는지 구조방정식 모형을 이용하여 분석하였다. 연구결과 놀이성과 eHealth 지식은 인지된 유용성과 인지된 사용 용이성에 유의한 영향을 주었고, 기술장애는 유의한 영향을 주지 않았다. 이 연구의 결과를 통해 대학생이 스마트폰을 통한 건강정보를 활용하기 위해서는 본능적인 동기부여인 놀이성을 높여야하고, 건강정보 어플리케이션을 활용하는 교육과 중재가 필요할 것으로 사료된다.

The purpose of this study was to examine how physical education class attitudes and playfulness influence school happiness among Korean elementary schoolers. The data was collected from 300 students in five elementary schools in I city. After the exclusion of 22 incomplete questionnaires, a total of 278 questionnaires were used for data analysis. For the data analysis, descriptive analysis, exploratory factor analysis, correlation analysis, and multiple regression analysis were employed. The correlation analysis revealed that every subset of variables of the study was positively inter-correlated. Multiple regression analysis showed that mental fluidity playfulness positively influenced every subset of school happiness variables. Physical animation playfulness positively influenced self-respect school happiness, optimism school happiness, and overall school happiness. Mental spontaneity positively influenced teacher relationship school happiness and overall school happiness. Physical education class attitudes positively influenced every subset of school happiness variables, and based on standardized regression coefficients, physical education class attitudes influenced school happiness variables more so than did playfulness. The findings indicate that physical education class attitudes and playfulness are important contributors for improving Korean elementary students' school happiness, and it is necessary to cultivate physical education class attitudes and playfulness in Korean elementary schoolers.

This study has two goals. The First is to develop and apply a step-by-step program and the degree to which students' mathematical skills. The second is to analyze mathematical attitude change around the first grade students was done. The program for learning complement number is composed of series of 5 steps and 11 classes. Play for learning complement number, taking into account the difficulty of the learning steps 1-5 are organized. First step is composed of the classes which fragmented pieces of shapes to complete the entire geometry with fun activities for the entire part of the concept of learning and it maintenance concepts and can naturally learn by associating step. In second step, tools to take advantage of the real world and collecting the conservative concept. 3rd steps is to repair the mathematical concept of the parish in the learning stage of expansion. 4th step is halrigalri, number cards, making ten games etc. 5th step is to verify the concept of complement number and number operation ability. The concept of complement number through fun activities can improve students' mathematical skills, and mathematical attitude change. Early in the program, students use the finger to throw acid in the process. Simple addition and subtraction calculations may take a long time and error, but more and more we progress through the program using the fingers is eliminated and a more complex form calculations was not difficult to act out.

Objective : The purpose of this study is to verify the effect of sensory integrative intervention on postural control and occupational performance (play) of the preschool child with postural disorder. Methods : Subject of this study was a 5 years and 8 month old boy. The subject underwent a sensory integration (SI) treatment which was part of the SI clinic course administered by the Korean Sensory Integration Society, in 2012. The treatment goal and treatment plan had established based on the evaluation results. Treatment was done with 11 sessions, the treatment activities and the adaptive responses of the subject were measured as outcome of the SI treatment. The goal of sessions were measured as Goal Attainment Scale, and re-evaluation was done on December in 2012. Results : During SI treatment, the subject was improved the stability of proximal body parts so that maintained Supine-Flexion Posture more than 20 seconds. He also showed increased attention span continuously about 1 activity on physical play. Conclusion : According to the results of this study, it was verified that sensory integrative intervention has positive effective on postural control and occupational performance (play) of the preschooler with postural disorder.

The Purpose of this study are to investigate the characteristics of the flame behavior of gasoline-methanol blended fuels in spark ignition engine. Ionization probe were installed at the cylinder head and piston in order to measure flame speed. Other parameter such as engine performance, fuel consumption rate and exhaust gas were measured. The results were as follows. 1. In the case of increase methanol contents in blend fuel, flame propagation speed were increased, and thermal efficiency of the engine were increased due to decrease of energy consumption rate. 2. In the case of fixed equivalance ratio, NO sub(X) in exhaust gas were increased in accordance with increase of spark advance, and mean effective pressure were decreased in accordance with increase of methanol contents. 3. CO and HC concentration were decreased in accordance with increase of methanol contents.
