In order to investigate physical and chemical properties, fatty acid and amino acid compositions of the Walnut (Juglans Sinensis) oil, quantitative analysis of the oil was carried out by using a HPLC. The results were as follows. 1. The walnut oil had 1.4720 of refractive index, 196℃ of smoke point, 135.6 of iodine value, 193.2 of saponification value and 1.1 of acid value in its physical and chemical properties, and 23.01%, respectively in the oil. 2. Fatty acid of the oil contained 72.83% of unsaturated fatty acids such as palmitoleic acid, linoleic acid and linolenic acid, and 12.711% of saturated fatty acids having even numbered carbons and 14.469% of saturated fatty acids having odd numbered carbons, The content of palmitic acid in this oi was the richest as it was 35.84%. 3. Total amounts of amino acids in the crude protein was 21,120mg/100g, and glutamic acid is the richest component in amino acids as 4.13mg/100g was contained in its content. And Assp., Tyr., Ileu,. and Arg. Were alo contained rich in their order. Total amounts of essential amino acid was 6,180mg/100g and the protein acore was 53.

Crystallization of PET copolymers with some comonomers were studied by differential scanning calorimetry and densitometry. The results as follows; (1) Crystallinities of PET were increased with increasing the densities of the PET copolymers. (2) Crystallization was delayed with increasing the viscosities of PET copolymers. (3) Crystallization temperature were decreased with increasing the mole percent of copolymers used.

The sea weds growing at the southern area of korea have been separated and classified into green algae, brown algae and red algae. The amino acids in sea weeds have been analyzed exclusively by gas chromatograms on the Gas chromatograph (Shimatzu GC-IC type) equipped with the flame Ionization Detector. Thses amino acids were again separated and identified by the Thin Layer chromatograph. Through these analyses, the follwing results were obtained : 1. All the essential amino acids were analyzed both by G.L.C. and T.L.C. 2. The amount of free amino acids was much more abundant in Monostroma nitidium. 3. In general, the amount of amino acids determined was larger in G.L.C. than in T.L.C. 4. Among the free amino acids detected glycin leucine and arginine were analyzed relatively in a larger amount, and those of cysteine and histidine were less. 5. The free amino acids of 7-11 kinds of the essential amino acids were detected in Gloipetis furcata J.Agardh, Gloiopetis J. Agardh, and chorda filum Lamouroux that had not been used for food, and in a fairly large amount.

When the object distance of a zoom lens with finite object distances is varied, we can fix the image at a fixed image plane by moving only one zoom lens group (autofocus group) without moving all zoom lens groups for the autofocus. We theoretically formulated and numerically calculated the moving distances of the autofocus group by using Gaussian brackets and a paraxial ray tracing method. The solutions of this method can be consistently and flexibly used in the initial design for the moving distance of autofocus group within these zoom loci in all types of zoom lens. Finally, in order to verify the usefulness of this method, we show that the moving distance of an autofocus group can be rapidly and diversely obtained in one example of $M_{5n}$ zoom lens type. 유한 물점의 줌 렌즈에서 물체거리가 변할 때에 전체 줌 렌즈의 각 군을 모두 움직이지 않고 특정한 한 개의 렌즈군(조출군)을 이동시켜서 고정된 상면에 결상시킬 수 있다. 이 조출군의 이동량(조출량)을 가우스 괄호법과 근축광선 추적식의 행렬표기법을 이용하여 이론적으로 유도하고, 수치해석적으로 이 조출량을 구하였다. 이 방법은 물체의 거리에 관계없이 모든 종류의 유한물점 줌 렌즈의 조출량에 대한 초기설계에 대해서 유연하면서 통합적으로 적용할 수 있다. 이를 증명하기 위하여 줌 렌즈에서 가장 복잡한 $M_{5n}$ 형태의 5군 줌 렌즈에 적용하여 조출량을 빠르게 신출할 수 있음을 보였다.
