This paper is concerned with the analytical comparison of the study-achievement between two kinds of technical jurnior college graduates-whose major subjects were mechanics and mechanical design-who graduated from general and technical high schools. The sample graduates were selected from 18 technical junior colleges, which in term were selected fron among 34 of the same kinds of colleges in our country. From such an analytical comparison, several conclusions were reached as follows. 1. The graduates who had finished technical high school had better records, in every subject, than the others. Therefore they had some advantages over the geaeral high school graduates. 2. The mean value in this paper is useful as a reference-standard for evaluating students. 3. In the graduation season a number of students are confused by preparations for the quslifying test with a resulting loss in final year achievement, so special schemes are needed to help students finish their school life in a more orderly way. 4. Generally, the technical high school finishing-graduates who had good records in mathmatics obtained higher marks than the others. Thus, in technical high schools, the significance of the mathmatics should be greater than before. 5. For the students who had finished general high schools, a special scheme will be indispensable to provide supplemental instruction in several subjects such as machine elements design, manufacturing processes and mechanical drawing.

In order to investlagte effects of Cyperus rotundus on the ovarian growth of rabbits, C. rotundus which grows in Korea was boiled in water. the extracts of C. rotundus was administrated orally from the 30 days old to the 90 days old rabbits. At the 60 days old and 90 days old, five number of rabbits were slaughted respectively. After laparatoming, the ovaries were immediately fixed in 10% formalin solution, embedded in paraffin, serially sectioned at 6u, and stained with H & E. The results are as follow: 1. At the 60 days old, the weight and length of ovary of rabbits administrated extracts of C. rotundus were 7.63±0.73mg and 7.02±0.45mm respectively. But in the control group, 7.85±0.65mg and 7.11±0.57mm. 2. At the 90 days old, the weight and length of ovary in the experimental group were 36.04±1.58mg and 9.68±l.04mm respectively but in the control group, 31.62±2.12mg and 9.12±l.12mm. The weight and length of ovary in the experimental group were significantly increased compared with those in the control group (P < 0.05). 3. At the 90 days old, several graffian follicles and corpus luteum in the ovary of 3 among 5 rabbits were observed. Typical follicular atresia and "Call Exner Body" were observed predominatly in the experimental group and also observed twin oocyte in the secondary follicle. Above results, C. rotundus in Korea is considered as harmful to herbivorous animals, if eat voraciously.
