For the studies an the Chemical compositions of Sweet potatoes grown in Korean soil, Suwon No. 118 and Suwon No. 147 were applied as the samples during growing period, and 15 varieties of sweet potatoes as the samples for comparisons among them. As the results ef the studies followings were obtained. Changes of the chemical compositions of root tuber during growing period. 1. Total weights of root tubers and mean weight per root tuber were increased gradually as grew with the values of Suwon No. 147 is higher than that of Suwon No. 118 except the weight of Suwon No. 147 on September 9. 2. The moisture content of the roots were fairy uniform. 3. While the starch contents and crude starch yield in the root tuber were gradually increased with almost parallel as grew except the values of Suwon No. 147 on September 7. were markedly higher. 4. The total weight of the Sweet potatoos per Dan-Bo (about 0.25 acre) showed increased values with Suwon No. 147 is higher than Suwon No. 118 except the unexpected lower weight of Suwon No. 147 on September 9. and the crude starch yield of Suwon No. 147 per Dan-Bo also showed higher values than that of Suwon No. 118 with almost parallel increase of them as they grew. 5. Reducing sugar contents of them showed gradual decreases at earlier stages then increases at latter stages as grew, and total sugar and sucrose of them also showed gradual increases except extremly higher contents of Suwon No. 147 and lover values of Suwon No. 118 on September 9. 6. Total protein and soluble protein contents of them showed that initial and last stages of the growth are in higher values but middle stages are fairy low values with a little changes of difference between total protein, and soluble protein. The comparisons among those varieties. 7. The moisture contents of root tuber varies from 63% to 72% among them. 8. The starch contents of Suwon No. 118 (23.9%) is highest value among them, Ko-Ke No. 14 and Won-Ki successively lower and Dae-Nong No. 45 is the lowest one. Crude starch yield (%) of Ko-Ke No. 14 and Won-Ki successively lower and Dae-Nong No. 45 is the lowest one. Crude starch yield (%) of Ko-Ke No. 147 is highest value, Suwon No. 118. Won-Ki are successively lower and Do-Ip is the lowest one. 9. Won-Ki is highest value in reducing sugar content, and Do-Ip No. 2 is lowest one in it. The sucrose content of Chil-Bok is highest and Won-Ki is lowest among them. Soluble total sugar content of Yu-Sim is in highest and Chun-Mi is in lowest value. 10. Total protein content showed that Suwon No. 147 is in highest value and Yu-Sim is in lowest one. On the other hand, soluble protein contents showed that Chil-Bok is in highest value and Yu-Sim is in lowest one.

이춘영,김재욱,조무제,김상순 한국농화학회 1969 Applied Biological Chemistry (Appl Biol Chem) Vol.12 No.1

As a one of the new methods for soybean protein food processings, an attempt was made to decompose steamed soybean protein to amino acids, peptides, and other water soluble forms by the use of protease produced by Aspergillus sojae, and extract them to use as additives of low protein foods or weaning-foods of children. In this paper, as a one part of this subject, the optimum condition, such as optimum pH, temperature, digestion period, raw material's mixing ratio with wheat meal, amount of water added, and effect of sodium chloride addition, to decompose and extract soybean protein were studied. They were obtained when mixing raw materials with wheat meal in the ratio of 10:4 and adding six folds of water at 40-45℃, pH 5-8 for 18 hrs. digestion. Although sodium chloride addition exerted an unfavorable influence upon the decomposition of the aforementioned materials, it was effective to prolongation of digestion period. Under the abovementioned optimum conditions, the maximum extractability of soybean protein as forms of amino acids, peptides, and other water soluble forms, was nearly 70 percent against protein content of raw materials.

≪설문해자(說文解字)≫ 정전(正篆)과 인용문(引用文) 독약자(讀若字)의 관계 탐석(探析)

李春永 영남중국어문학회 2020 중국어문학 Vol.0 No.85

ZhengZhuan(正篆) included in the ShuowenJiezi(說文解字) is written in Sound, and 49 of ZhengZhuan(正篆) quote the phrase of Confucian scriptures. In addition, Chinese Characters in the phrase use DuRuozi(讀若字). There are DuRuo(讀若), DuYu(讀與) and DuYouRuo(讀又若) in the phonetic language of these materials. The 經典 phrases quote 3 phrases in LunYu(論語), 20 phrases in ShiJing(詩經), 4 phrase in ShuJing(書經), 9 phrases in Yi(易), 9 phrases in ChunQiuZuoZhuan(春秋左傳), 1 phrase in ChunQiuGongYangZhuan(春秋公羊傳), 3 phrases in ErYa(爾雅). Quoting the Confucian scriptures phrase has the effects of limiting the sound of the DuoYinZi(多音字) and making the meaning more clearly. This emphasis great value of the academic achievements of the XuShen(許愼), who is one of the outstanding literary arts scholars at the time. In the DuRuoZi(讀若字) of the quoted construction, there are 20 Chinese characters with the same pronunciation and different shapes, 7 Chinese characters with the same pronunciation and the same shape, 1 JiaJieZi(假借字) with the same pronunciation, 19 Chinese characters of the same ShengFu(聲符), and 2 Chinese characters with similar pronunciation. From this, it can be seen that XuShen(許愼) attempted to express the pronunciation of Chinese Characters as clearly as possible by quoting the phrase of Confucian scriptures in the pronunciation of ShuowenJiezi(說文解字). Also, through the pron- unciation relationship between ZhengZhuan(正篆) and DuRuozi(讀若字), it is clearly shown that the basic function of ShuowenJiezi(說文解字) ‘DuRuo(讀若)’ is in the pronunciation notation.

대두(大豆) 단백질(蛋白質)에 관(關)한 연구(硏究) 제2보[第二報]-7S Globulin중의 복합단백질(複合蛋白質)의 분리(分離) 및 그 구성(構成) Subunit에 대하여

이춘영,김인수,김수언,Lee, C.Y.,Kim, I.S.,Kim, S.U. 한국응용생명화학회 1977 Applied Biological Chemistry (Appl Biol Chem) Vol.20 No.1

대두(大豆)(Glycine max cultivar Gwang-gyo)의 각 성숙시기(成熟時期)에 나타나는 7S globulin을 분리하여 Davis 방법(方法)에 의한 전기영동과 PAWU용매에 의해서 유리(遊離)되는 그들의 subunit를 전기영동한 결과 7S globulin중의 복합단백질간(複合蛋白質間)에는 그 구성(構成) subunit에 유사성(類似性)이 있음을 시사하였다. 7S globulin의 복합단백질(複合蛋白質)을 DEAE-Sephadex A-50으로 크로마토그라피하여 분리하였다. 이때 pH 7.6의 인산완충액(燐酸緩衝液)에서 NaCl의 농도구배(濃度句配)가 0.28M부터 0.40M 사이에서 두 개의 분획(分劃)으로 분리되었다. 이들 명(名) 단백질(蛋白質)의 subunit를 5M urea와 1% SDS로 유리(遊離)시켜 7.5% acrylamide-PAWU gel과 5.6% acrylamide-SDS gel에서 전기영동하였다. 그 결과 subunit의 하전량(荷電量)에 의해서 분리되는 PAWU gel전기영동에서 7S globulin이 5개의 주 분리대로 분리되고 그중 2개의 분리대가 7S-A globulin과 7S-B globulin에 공유(共有)되어 있었다. 또 subunit의 분자량(分子量)에 따라서 분리되는 SDS gel 전기영동에서는 7S globulin이 7개의 주 분리대를 나타내는데 그 중에서 3개의 분리대가 7S-A와 7S-B 분획에 공유(共有)되어 있었다. 따라서 7S globulin의 복합단백질간(複合蛋白質間)에는 구성(構成) subunit간(間)에 유사성(類似性)이 있는 것으로 나타났다. The multiple 7S globulins composed of two fractions (A and B) in the electrophoresis with Davis' method were isolated at different stages of the soybean seed development. Electrophoresis of their subunits liberated in PAWU solvent [phenol-acetic acid-water (2 : 1 : 1) solution plus 5M urea] yielded 4 major bands. Observation of both the electrophoretic bands of the multiple 7S fractions(7S-A and 7S-B) and those of their subunits was suggestive of a similarity of the subunit pattern between two 7S fractions. The two fractions in multiple 7S globulins were isolated with DEAE-Sephadex A-50 column$(2.0{\sim}100cm)$ chromatography. They were separated into 2 fractions in a linear gradient concentration of 0.28 to 0.40M NaCl with phosphate buffer (pH 7.8) containing 10mM ${\beta}-mercaptoethanol$(ME). The isolated protein was dissociated into subunits with two different solvent systems; in PAWU solvent and in Tris-HCl buffer(pH 8.0) containing 1% sodium dodecyl sulfate (SDS) and 40mM ME. The dissociated subunits were subjected to electrophoresis in PAWU-treated 7.5% acrylamide gel and in 1% SDS-treated 5.6% acrylamide gel. In PAWU gel electrophoresis, total 7S globulin was separated into 5 major bands, two of which were occupied in common by two 7S fractions(7S-A and 7S-B). In SDS gel electrophoresis, total 7S globulin was separated into 7 major bands, three of which were overlapped with the subunit of the two 7S fractions. The above results alluded us to the presence of a common and/or similar subunit between the multiple 7S globulins.

논문(論文) : 해섭(蟹攝) 1,2등(等) 글자의 현대 한국 한자음(漢字音) 형성 배경 탐석

이춘영 영남중국어문학회 2015 중국어문학 Vol.0 No.68

Chinese characters assimilated into Koreans have been built on the pronunciation environment of the Korean to the needs of contemporary language preferences. They have been passed through hosts of selection process and then have been formed into the sounds of Modern Sino Korean characters. In this paper, we see the characters of XIE SHE YI DENG & ER DENG(蟹攝 1等·2等)’s vowels, and analyse the formation background of Vowels sounds in Modern SinoKorean character in phonetical points, and also examine the three reasons of the formation background as follows. Those are transformation of pronunciation in China, polyphone in Chinese, and characteristic transformation of pronunciation in Korea. First we analyse six different types in the reason of pronunciation transformation in China. First, Characters of HA·JIA· JIE·TAI·GUAI(哈·佳·皆·泰·쾌韻) in KAI KOU YI DENG & ER DENG (開口1·2等)’s combined pronunciation “ㅐ”; Second, Characters of JIA· TAI(佳·泰) in KAIKOU(開口)’s divided pronunciation ‘ㅖ’ in MING and Qing dynasty. Third, Characters of JIA·JIE·TAI·GUAI(佳·皆·泰·쾌韻) in HE KOU YI DENG & ER DENG(合口 1·2等)’s combined pronunciation “ㅙ”; Fourth, Characters of JIA(佳) in HE KOU(合口)’s ivided pronunciation “ㅘ”; Fifth, Characters of JIE·TAI(皆·泰) in HE KOU(合口)’s reflected pronuncitaion “ㅚ”; Sixth, Characters JIA(佳) and JIE(街) of JIA(佳) in KAI KOU ER DENG(開口二等) with JIAN(見)’s pronunciation “ㅏ”. In the acceptance process of polyphone in Chinese, it had been selected only a few of pronunciations in Korea. In the transformation process of characteristics pronunciation in Korea, we especially analyse the three different types, considering easy of pronunciation of Korean people and language environment of Modern SinoKorean characters situation. First, vowel “ㆎ” changed into “ㅐ”; Second, KAI KOU HUA (開口化) in HE KOU YI DENG(合口1等) of TAI YUN(泰韻) with consonants DUAN·TOU·DING(端透定); Third, Characters in KAI KOU (開口) changed into HE KOU(合口).

1. Through out the entire stage of growth, the amount of nutrients, number of tillers and of spikes increased in the Simagcalin treated plot as compared with the control. The treated plot showed healthul growth at the later growing stage. On the other hand. management of irrigation water resulted in raised the grain straw ratio and retarded the culm height about 10%. 2. Application of Simagcalin greatly increased the content of phosphorus and magnesium at the harvesting time. The culm and sheath analyses are recommendable for the determination of magnesium deficiency. 3. The controled irrigation would effect root activity as the main factor, and Simagcalin might act as a secondary factor. 4. While the application of phosphorus may not affect the yield components, The basic elements in Simagcalin may enhance the uptake ov nutrients under heavy application of nitrogn.
