This experiment is a quantitative experiment where insoluble Vitamins E and K are extracted from the yolk of the spawning which was fed by by-products of tangerine, carrot, or Japanese apricot. Finally the purpose is to raise contents of the insoluble Vitamins E and K inside the yolk of the spawning. The saponification method through ${\alpha}$, ${\alpha}$ - dipyridyl was used to determine the content of Vitamin E. Diethyl dithiocarbamate assay was used to examine the content of Vitamin K. The contents of Vitamin E in egg yolks of chicken fed by by-products of tangerine, carrot, or Japanese apricot increased 2 - 3 times compared to control egg, while the contents of Vitamin K almost no changed.

The contents and their seasonal changes of non-volatile organic acids and sugars of various fruits in Korea, apricot(maesil), peach, grape, apple and pears were measured. The organic acid contents were determined by gas chromatography and the free sugars were detected by thin layer chromatography. The results were as follows: 1) The common non-volatile organic acids found in those fruits were oxalic, fumaric, succinic, maleic, tartaric and citric acids: though their contents varied from almost none to 3430mg/100g. 2) Malic acid was contained in all above fruits with generally the highest contents ranging $18{\sim}3430mg/100g$ among different fruits. In every fruits oxalic was the least contained among other organic acids, almost none to trace except apricot(maesil) which contained 10.8mg/100g. 3) It seemed that generally all the non-volatile acids contents decreased after ripening except maleic acid and the cases of an apple and a pear varieties where they increased. 4) Glucose and fructose were detected in all fruits both matured and unripened by thin layer chromatography. Maltose was found in apricot(maesil), peach, grape and apple. Sucrose was detected in apricot(maesil), peach, grape, apple and pear.

Picrate, enzyme-picrate and instrumental analysis methods using IC (Ion Chromatography) and HPLC (High Performance Liquid Chromatography) were compared for their effectiveness in determining cyanide in extracts of Maesil, which is classified as a harmful substance. First, the picrate method showed the shortest analysis time (about 5 hr). The color of picrate paper changed at 0.01 mg/$200\;mL\;CN^-$. However, it was difficult to detect cyanide from amygdalin of glucosides. Second, we performed a qualitative analysis for total cyanide (free cyanide and cyanide from amygdalin) by the enzyme-picrate method using $\beta$-glucosidase and a quantitative analysis by spectrophotometry. Finally, analysis of cyanide by IC and HPLC required the longest determining time (about 17 hr) as well as pretreatment for each free cyanide and amygdalin. These results suggest that enzyme-picrate is the most effective analysis method for the detection of cyanide in Maesil extracts.

The changes in firmness, mineral compositions and pectic substances of Mume(Prunus mume Sieb. et Zucc) fruits during maturation were determined. An average weight of the fruits in 92days after full bloom was increased during maturation proceeded up to the range of 212∼232%, as compared with that of 64days. The rate of weight increase of 'Ohshuku' fruits was 257%, and it was highest among four varieties. The ratio of stone to flesh weight was decreased, but the diameter of the flesh of fruits was increased during maturation. The firmness of 'Koume' fruits was rapidly decreased from 78days after full bloom. Three varieties, except 'Koume' fruits, showed similar changes in firmness. Potassium content of fruits was 85%. Calcium and Mg were decreased as the flesh of fruits became plump. The ratios of hydrochloric acid-soluble pectin(HSP) , water-soluble pectin(WSP), sodium hexamethaphosphate-soluble pectin(PSP), and sodium hydroxode-soluble pectin(SSP) contents to the total pectin content of the fruits were 66∼76, 8.4∼19.7, 5.4∼7.5 and 7.1∼8.3%, respectively. The total pectin content was increased up to 71days after full bloom, but it was decreased thereafter. Also, a significant increase of WSP and a decrease of HSP were observed during the softening process of fruits.

To select fruit trees for urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Prunus mume, Ribes nigrum, Rubus fructicosus, and Vaccinium corymbosum 'Reka', growth characteristics of these 6 species were compared and effect of trickle irrigation and shading on the growth of these fruit trees were investigated that these treatments were carried out how much these trees are endurable exposed to improper conditions. After passing the winter, E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, and V. corymbosum 'Reka' showed the highest survival rate, in contrast to R. nigrum with the lowest of 56.0%. In 9 months after planting, the hight growth rate of 62.3% was shown in P. mume but that of E. umbellata var. coreana was stagnant during experimental period. Flowering rate over 80.0% were shown in E. umbellata var. coreana, M. domestica 'Alps Otome', R. fructicosus, and V. corymbosum 'Reka'. On the other hand, R. nigrum has not ever flowering branches. Other species except E. umbellata var. coreana and R. nigrum have about 10 days in flowering duration. After flowering, fruition rate has shown significant difference among 6 species. As a result of both treatment of trickle irrigation and shading, leaf area and leaf weight of E. umbellata var. coreana, M. domestica 'Alps Otome' significantly inceased with treatments that have not affected other species. Based on these result, it is possible to deploy suitable fruit trees to specific garden condition after selecting various fruit trees.

일본 자동차타이어 협회에서 지난 3월에 발표한 82년도 일본 자동차용 타이어의 생산ㆍ판매실적을 보면, 회원 7개사의 총생산 실적은 약 71만 4,000톤으로 전년비 7% 감소되었고, 판매도 72만 3,000톤으로 전년비 6% 감소되었다. 교환용타이어는 3년 연속, 신차용 타이어는 2년연속으로 각각 전년을 하회하고 있으며, 지금까지 확대일로에 있던 수출부문도 전년비 12% 감소로 대폭적으로 떨어졌다. 그러나 생산합리화의 추진으로 재고는 1개월 이내의 "적정수준"에 있다. 한편, Radial타이어의 생산비율은 TB용이 46%이고 , PC용이 77%로 거의 상한치에 달하고 있다.<편자주>
