This study is to research into changes of contents of dance in preschool education and to show propriety for that preschool child?s dance has to be educated as ?Choom-no-ri? in field of preschool education and has to exist as not movement education but a proper noun called ?Choom-no-ri?. To make an analysis about preschool education course is a method to well know exchange in contents of dance in preschool education. So I analyzed preschool education course of Korea from 1st and 6th now. And compared preschool education method of Japan for knowing the current of dance education in the world. And knew that preschool child?s dance in both nations must become a dance laying stress on play I.e. ?Choom-no-ri?.

액-액계의 용매추출탑에서 맥동에 의한 액정형성기구 및 액적크기 예측을 규명하였다. 본 연구에서는 맥동의 주파수, 진폭 및 맥동 속도의 변화에 따른 액적크기를 kerosene-Sodium hydroxide계에서 Hexamethylene Diamine에 의한 Encapsulation Technique Drop formation models were formulated in the pulsed liquid-liquid contacting column on the basis of force balance and momentum balance, and theoretical values were compared to experimental values which were determined by means of encapsulation technique in the aqueous-kerosene system. Our results conformed that drop formation mechanism is composed of two-step process, and that momentum balance model is superior to force balance model. According to the dependency of drop size on pulsing amplitude and frequency, the drop diameter tended to decrease with the increase of pulse velocity.

본 논문에서는 피라미드 부호화에서 몇가지 수행이 간단한 방법을 사용하여 0.3~0.5bits/pel의 고감축율에서도 양호한 품질의 영상을 얻고자 하였다. 이를 위하여 Laplace 평면 구성의 궤환방식, 3차원 예측기, 그리고 중앙집중 양자화기를 부호화시 도입하였다. 또한 최하층의 비트율을 대폭 감축하기 위해 조건부로 전송하는 방식과 전송하지 않고 에지 선명화하는 방식을 새로이 적용하였다. 실험 결과, 에지 선명화 방식에 의한 부호화시 0.3bits/pel의 엔트로피로 구해진 비트율에서도 비교적 양호한 품질의 영상을 얻을 수 있었다. In this paper, several simple approaches to Laplacian pyramid coding have been presented for obtaining reasonably acceptable image quality even at low bit rates of 0.3-0.5 bits/pel. For this purpose, the feedback construction of each Lapliacian plane, 3-dimensional prediction and three-level center-clipping quantization are introduced into the coding procedures. For greatly reducing the bit rate of the bottom layer, two new schemes of conditional transmission and edge sharpening without transmission are used. In experiments, our latter sheme has yielded the total bit rate of about 0.3 bits/pel while retaining reasonably acceptable image quality.
