  • The present study examined the effect on children's creativity of using painting masterpieces with activities of physical expression. Subjects were 32 five-year-old kindergarten children assigned to control or experimental groups. The experimental group participated in physical expression activities using painting masterpieces twice a week for six weeks. Figure paintings of such famous artists as Kim Hong Do, Kim Deek Shin, Degas and others were presented by Projection TV in connection with physical movement in the classroom. Creativity was tested by Torrance Tests of Creative Thinking(2002). Results showed that the experimental group exhibited positive change in creativity scores and the sub-areas of creativity(fluency, originality, abstractness of titles, elaboration, and resistance to premature closure).

  • This study of the effectiveness of various art programs took place in Gwangju with asample of 60 four- to five-year-old children from three kindergartens. The children were assigned to one of three experimental groups : 20 children in the picture book group(experimental group 1), 20 children in the famous paintings group(experimental group 2), and 20 children in the traditional group(control group). Data were analyzed by ANCOVA using the scores of the pre-test as covariance. Results showed that the picture book and the famous painting art programs affected young children's art ability more positively than the traditional art program.

  • 본 논문에서는 조명용 LED 구동을 위한 최소원가형 전력변환장치를 제안하였다. 부하측의 전압과 전류 피크값을 낮춤으로써 스위칭 손실을 줄이면서 플리커 현상도 최소화하고, 입력전압과 전류를 동상에 가깝게 제어를 하여 역률을 최적화 하였다. 전해커패시터를 없앰으로써 장수명화에 기여를 하였고, 필터에 사용되는 소량의 용량은 필름커패시터를 대체하여 부하측 전류의 안정화에 기여하였다. 본 연구의 결과는 LED 구동용 전원장치의 최적화에 기여하여 장수명화 및 비용을 최소화할 것으로 기대된다.
