The properties of Cheju native mares` casein investigated and compared with Throughbred mares` casein by polyacrylamide gel electrophoresis (PAG), Sepharose 6B gel filtration and DEAE-cellulose column chromatography. Cheju native mares` casein separated in main three components, αs-, β-, k-casein by polyacrylamide gel electrophoresis in the presence of 2-mercaptoethanol. On Sepharose 6B column, 3 fractions were obtained from acid casein: the first with k-, the second with αs-, β-, k-and the thud with mainly αs-, β-casein. Acid casein was fractionated into 5 fractions on DEAE-cellulose column with 0.01 M-Imidazole-HCl buffer (pH 7.0). The major components of the identified fractions are: fraction A, k-casein: B to C, mainly β-cassein: D to E, αs-casein.

Seasonal changes of milk components, proportion of rejected milk, bacterial counts and the relationship between milk fat and solid-not-fat (SNF) of farm milk were studied over a period of two years(1987-1988). The results obtained were as follows: 1. Mean values of milk fat, protein, lactose, SNF and total solid were 3.72, 3.19, 4.60, 8.68, and 12.40 % respectively. 2. A significant correlation coefficient exsisted between milk fat and SNF content (P$lt;0.01). The coefficient and regression equation in the first and second year were r=0.347, Y=7.637+0.2777X and r=0.292, Y=7.715 +0.254X respectively. 3. The incidence of rejected milk was 0.75% of total quantity of raw milk recieved. It was higher rejected milk percentage than other region of the mainland and was affected greatly by season. 4. Coli-form bacterial count of the raw milk samples showed 46.3%m were under 100,000 cfu/ml and 53.7% were over 100,000 cfu/ml. 5. More than 4 x 10^7 cfu/ml live bacteria were counted in the raw milk with 53.8 % of the farm surveyed.

본 연구에서는 기존의 성인용 전산화 인지훈련 프로그램 콘텐츠 및 문헌들을 분석하여, 뇌병변장애아동의 참여도와 흥미를 높여줄 수 있는 VR 기반 인지훈련 프로그램을 개발하였다. 본 연구에서는 뇌병변장애아동을 위한 인지훈련프로그램으로 1)시각화 및 추론 훈련, 2)주의력 및 기억력 훈련, 3)일상생활훈련(ADL) 3가지 카테고리와 13가지 하위 콘텐츠로 구성된 VR 기반 동작인식 훈련 프로그램을 개발하였다. 또한 아동들의 참여도 및 흥미를 높여줄 수 있는 인터페이스등을 추가적으로 개발하여 프로그램에 적용하였다. This study analyzed the contents of existing computerized cognitive training programs for the training participation and interest of the children with brain lesions. VR (Virtual Reality) based cognition training programs were developed for the children with brain lesions to participate with interest. The VR-based cognition training program for children with brain lesions developed in this study consists of contents in three categories: 1)visualization and reasoning training; 2)attention and memory training; and 3)daily life training(ADL : Activities of Daily Living) with 13 detailed contents and interfaces capable of increasing partipation and interest of the children.
