High level of α-linoenic acid was present in P. frutescens Britton var. japonica (67.9％), P. frutescens Britton var, acuta (66.0％), lsodon japonicus (65.2％), l. inflexus (59.0％), l. serra (57.3％), Mosla dianthera (60.9％), Nepeta cataria (58.3％), Agastache rugosa (58.5％) and Elsholtzia ciliata (46.2％), and followed by linoleic acid (11.2-32.1％) and oleic acid (9.3-12.2％). However, linoleic acid was the most predominant component in the total lipids of Clinopodium chinense var. parviflorum (62.4％), Ametystea caerules (82.9％), Leonurus sibricus (60.9％) and Scutellaria baicalensis (63.4％), with very small amounts of α-linolenic acid (0.4-3.1％). The total lipids of Salvia splendens, Lycopus maackianus and Mosla punctulata also contained linoleic acid of 31.3％, 48.8％ and 53.4％, with a considerable amount of α-linolenic acid of 34.5％ 27.0％ and 16.7％. Palmitic acid was the major saturated fatty acid in all the oils investigated (4.1-14.2％). 4) Fatty acid profiles of neutral lipids bore a close resemblance to those of total lipids in all the seed oils, but different from those of glycolipids and phospholipids. Fatty acid composition pattern of glycolipids and phospholipids showed a considerably increased level of saturated fatty acids (19.0-66.8％, 17.8-35.2％) mainly composed of palmitic acid and stearic acid, and a noticeable low level of unsaturated fatty acids (41.2-80.9％, 64.7-82.1％) which was ascribed to the decrease in α-linolenic acid of high α-linolenic acid seed oils, and in linoleic acid of high linoleic seed oils, compared to that of total lipids and neutral lipids.

The results obtained by survey on 599 respondents of different age groups for preference of 84 prepared foods were subjected to statistical principal component analysis, factor analysis, analysis of variance, scheffe verification, and discriminant analysis so as to find a structure of preference for foods. The results may be summarized as follows: 1. The results of the factor analysis indicate that 84 prepared food items may be classified into 3 groups and that by knowing an indvidual's preference to one prepared food, one can presume his preference to the others in the same group without carrying out actual test. 2. The results from an analysis of variance showed that most of primary school children extremely liked snacks, seniors liked Korean cooking, primary school children and collegians had weaknesses for western cookings while kindergarden children and adults over 50 years old disliked them.

Annual mean precipitation in kyungpook area are 1044 mm, about 115 mm less than annual mean precipitation of Korea amounts to l1S9mm, and found to regionally unequal. 2. Monthly mean rainfall of July is 242.2mm, 23.2%, August 174.2mm, 16.7%, June 115mm, 11% and September 114.2mm, 10.9% and Rainfall depth of July-August are more than 40% of annual precipition. This shows notable summer rainy weather by typoon and low pressure storm and seasonal unbalance of water supply. 3. The relation among the maximum precipi.tation per day, per two continuous days and per three contnous days are caculated and the latter is found 31.0% increased rate of the first and the last 48.2% increased rate of first. 4. Probability precipitation in Kyungpook area are shown as 9.0%(5 year), 13.3%(10 year), 17.7%(20 year), 23.1%(50 year), 27.0%(100 year) and 31.1%(200 year) increased rate of each recurrence year compared with observed average annual precipitation. 5.

Effect of initial PH on the lipid accumulation and fatty acid composition of some species of mold were investigated. The maximum lipid content content produced by Aspergillus niger var. macrosporus was 17.5% at PH 3.5, by Aspergillus fumigatus 23.5% at PH 3.5 by Penicillium spinulosum 12.0% at PH 4.0 and by Penicillium notatum 7.3% at PH 4.0. The major fatty acids were palmitic, stearic, oleic and linoleic acid in all experimental molds. At PH from 4.5 to 6.0, the proportion of linoleic acid was increased and those of palmitic and oleic acid were decreased with rising in PH, therefore, degree of lipid unsaturation was increased in all experimental molds.

The crude lipid contents of dried sea food products varied remarkably from 1.2 to 29.9% for dried fish products, from 2.8 to 12.3％ for dried mollusk ones, and from 0.1 to 2.3％ for dried seaweed ones. In fatty acid composition of dried fish products, the saturated acid was the most predominant component for dried anchovies, hair tail, Kstsuobushi, the monoenoic acid was the most predominant one for dried yellow corvenia, flat head, common carp, sea eel and conger eel. And the polyenoic acid was the most abundant one for dried cod. Allaska pollack, flounder, sole fish, ray, smelt and sardine. The major fatty acids of these dried fish products were 16:0, 16:1, 18:0, 18:1, 20:5 and 22:6. Fatty acid composition of dried mollusk products were mainly consisted of polyenoic acid, and followed by saturated acid, monoenoic aced. The major fatty acids of these products were similiar to those of dried fish products. And in case of dried seaweed products, saturated acid such as 14:0, 16:0 was the most predominant component, while polyenoic acid was abundant one in dried laver and sea mustard. The main fatty acids of dried seaweed products were 14:0, 16:0, 18:1, 20:1, 20:4, and 20:5. Judging from the results, dried sea food products were abundant of the highly unsaturated fatty acids in spite of the drying processing and storage.

The effects of procedures for preparation of fatty acid methyl esters for gas chromatography were investigated. A quantitative comparison of four procedures for the preparation of the fatty acid methyl esters from Korean sesame seed lipids which can be representative of fatty acid ranges of Korean vegetable oils has been made. The procedures employed were BF3-methanol, HCI-methanol, sodium methoxide-methanol, and tetramethylammonium hydroxide-methanol. Twelve fatty acids ranged from 14:0 to 24:0 were identified in the lipids from Korean white and black sesame seeds. All four procedures gave similar results for the fatty acids, 16:0, 18:0, 18:1, 18:2, and 18:3 present in the range of 1~44% but only in the HCI-methanol procedure, the fatty acids, 16:1, 20:0, 22:0, 24:0 present in the range of 0.02~1% showed the lowest values. When using tetramethylammonium hydroxide-methanol procedure for determination of total fatty acid composition from white and black sesame seed lipids, unsaponifiable matters including sesamol, sesamolin and sesamin present in the seed lipids are not removed from the resulting reaction mixture. Thus the transesterification mixture is used without further treatment for injection into the gas chromatography. However, the gas chromatographic analysis of the transesterification mixture showed that the unsaponifiable matters had no effect on the fatty acid composition of the seed lipids. From the results, it appears that the BF3-methanol, sodium methoxide-methanol and tetramethylammonium hydroxide-methanol procedures can be used to prepare fatty acid methyl esters from Korean vegetable oils. Among the methods, the tetramethylammonium hydroxide-methanol procedure, which give total fatty acid composition, glyceride fatty acid composition and composition of free fatty acids present, appears to be a simple, convenient and quantitative procedure and applicable to samples containing broad ranges of fatty acids.

쥐의 암컷에서 유리불포화지방산, 인지질, creatinine 및 prostaglandin의 혈액내 함량을 측정하여 실험 동물로써의 생리적인 기초자료를 제공하고 또한 임신일수와 분만후 경과시간에 따른 이들 성분의 변화를 관찰하여 임신과 분만에 미치는 영향에 대하여 예비정보를 제공하기 위하여 본 실험을 실시하였다. 이러한 목적을 달성하기 위하여 5마리의 임신하지 않는 쥐를 대조군으로 하고 임신한 쥐 35마리를 5마리씩 7군으로 나누어 (5개의 임신군과 2개의 분만군) 100일 동안 실험을 실시하였다. 본 실험에서 얻어진 결과를 요약하면 다음과 같다. 1) 쥐 암컷의 혈청내 유리불포화지방산 함량은 의 범위였고 각 실험군간에는 현저한 차이가 없었다. 그러나 임신21일군이 로 비교적 낮은 수준이었다. 2) 쥐 암컷의 혈청내 인지질 함량은 의 범위였고 임신21일군과 분만후 36시간군이 비교적 낮은 수준이었지만, 각 실험군 및 전체임신군과 전체분만군의 평균함량간에는 현저한 차이는 없었다. 3) 쥐 암컷의 혈청내 creatinine 함량은 의 범위였고 각 실험군간에 현저한 차이가 안정되지 않았지만, 임신21일군이 비교적 높은 수준이었다. 4) 쥐 암컷의 혈액내 prostaglandin 함량은 로써 대조군()에 비하여 임신9일(), 12일() 및 15일()군 등이 낮은 수준인데 비하여 임신18일군()부터 대조군보다 증가되기 시작하여 임신21일군()과 분만후 12시간군()까지 계속 증가하여 최고수준에 달했으며 분만후 36시간군()도 대조군에 비하여 현저하게 높은 수준이었다. 그리고 각 실험군간에는 현저한(p<0.01)차이가 안정되었고 특히 전체임신군의 평균함량이 로써 대조군에 비하여 낮았고, 전체분만군의 평균함량이 로써 대조군과 천체임신군의 평균함량보다 매우 높은 수준이었다. 5) 쥐 암컷의 혈청내 유리불포화지방산, 인지질 및 creatinine 함량은 임신일수와 분만후 경과시간에 따라 큰 영향을 받지않는 것으로 생각되지만, 임신말기와 분만후에 약간의 변화가 있었다. 6) 쥐 암컷의 혈액내 prostaglandin 함량은 분만개시에 중요한 역할을 한다고 생각된다.
