이춘영,김호식,김재욱 한국농화학회 1963 Applied Biological Chemistry (Appl Biol Chem) Vol.4 No.1

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.

性善之善不与恶对

이춘영 성균관대학교 유교문화연구소 2011 儒敎文化硏究(中文版) Vol.0 No.16

Dao Xue in Sung Dynasty argues that Li is the metaphysical fundament of the original goodness of human nature. This argument contains two difficulties: 1. Its confliction with Confucian classical theories; 2. If human nature is originally good, what is the origin of evil?No matter he belongs to Li Xue or Xin Xue, all scholars of Dao Xue have to face these two difficulties. Zhang Jiucheng insisted that the original goodness is not opposed to evil. His theory is remarkably different from the thoughts of his contemporaries, such as Cheng brothers, Zhang Zai, Yan Shi, Zhu Xi, and Hu Hong. The Comparison of their main theories on this topic can show us the inheritance relationship and the development of the theory of original goodness of human nature in Sung Dynasty, as well as exhibit the solutions of the forementioned two difficulties. 宋代道学以天理作为性善论的形而上学基础,这暗含了两个困难:一、与传统儒家经典之间的矛盾;二、性之本体至善无恶,那么恶的来源何在。道学中无论是理学还是心学都必须面对这两个困难,并给出解答。本文以张九成“性善之善不与恶对”的思想为例,通过张九成与二程、张载、杨时、朱熹、胡宏等思想家的比较,展现性善论在宋代发展完善的思想脉络,并厘清道学对以上两个困难的解决途径。特别是通过讨论恶的来源问题以及善恶究竟是实质义还是形式义,来分析二程、张九成、朱子与胡宏之间对性善的不同理解。

≪譯語類解≫ 左右音에 나타난 知照組의 특징 探析

이춘영 동아인문학회 2015 동아인문학 Vol.32 No.-

In 1690, The Joseon Dynasty’s interpreters who with the help of the chinese’s advice was made a book named “Yeogeoyuhae(譯語類解)”. In this book, includes the then chinese vocabulary and pronunciation of words whit the form of left pronunciation and right pronunciation. Left pronunciation is more conservative Zheng-Yin(正音) pronunciation, and right pronunciation is reality chinese pronunciation. Both of the left pronunciation and right pronunciation was recorded in Korean alphabet. Thus this book has become an important literature of the end of 17th century’s 正音 notion and then reality chinese pronunciation. In this paper, words of group 知照’s left and right pronunciation has been analyzed by into the modern chinese pronunciation phenomena. The results of the analyze are as follows. Left pronunciation in “Yeogeoyuhae(譯語類解)” was preserved the voiced sounds; “devoicing” and “pronunciation change into [-uo] in Yao- Yun(藥韻) of group Zhi-Zhao(知照)” was not reflected in the outcome. However in the “group ZHI-ZHAO(知照) completed merger” & “front- close vowels in group Zhi-Zhao(知照) changed into non-front-close vowels” & “opposition between [tʂɥ] and [tʂu]” & “pronunciation change into [-uaŋ] in Jiang-Yun(江講絳韻) of group Zhi-Zhao(知照)” were reflected to some extent. According to the results we can know that Left pronunciation in “Yeogeoyuhae(譯語類解)” was wrote by Zheng-Yin(正音) concept which was admixed old chinese phonology and 17th century’s reality chinese pronunciation. On the other hand, right pronunciation can clearly prove that characteristic in “devoicing” & “group Zhi-Zhao(知照) completed merger” & “front-close vowels in group ZHI-ZHAO(知照) changed into non-front-close vowels” & “opposition between [tʂɥ] and [tʂu]” & “pronunciation change into [-uaŋ] in Jiang-Yun(江講絳韻) of group Zhi-Zhao(知照)” & “pronunciation change into [-uo] in Yao-Yun(藥韻) of group Zhi-Zhao(知照)”. 1690년 조선에서 譯官들이 중국인의 조언을 토대로 만든 《譯語類解》에는 당시 중국 口語 어휘와 단어의 중국 발음이 左音과 右音의 형식으로 표기되어 있다. 左音은 비교적 보수적인 正音을 기록하였고, 右音은 실제 중국 발음을 諺文으로 기록하고 있다. 그러므로 17세기 말 正音개념과 실제 발음현상을 연구할 수 있는 중요한 자료가 된다. 본 논문에서는 《譯語類解》 左音과 右音에 나타나는 知照組 글자들의 어음을 근대 한어 어음현상의 각도에서 분석하였고, 연구의 결과는 다음과 같다. 《譯語類解》의 左音에는 全濁音이 보존되어 있고, ‘濁音淸化’와 ‘藥韻 知照組 〔-uo〕음 변환’은 반영되지 않고 있으나, ‘知照組 합병의 완성’·‘知照組 細音의 洪音化’·‘〔tʂɥ〕·〔tʂu〕의 대립’·‘江講絳韻 知照組 〔-uaŋ〕음 변환의 완성’은 어느 정도 반영하고 있다. 《譯語類解》의 左音은 古音과 17세기 중국 실제 어음현상의 영향이 혼합된 正音개념의 표기임을 알 수 있다. 반면에 《譯語類解》의 右音은 17세기 후반 중국 口語에서 知照組 글자는 ‘濁音淸化의 완성’·‘知照組 합병의 완성’·‘知照組 細音의 洪音化’·‘〔tʂɥ〕·〔tʂu〕의 대립’·‘江·講·絳韻 知照組 〔-uaŋ〕음 변환의 완성’·‘藥韻 知照組 〔-uo〕음 변환’의 특성이 나타나고 있음을 명확하게 증명하고 있다.

Candida 속 Lipase 의 활성에 영향을 미치는 제인자(諸因子)에 관한 연구

이춘영,김성렬,박윤중 한국농화학회 1971 Applied Biological Chemistry (Appl Biol Chem) Vol.14 No.3

An enzyme preparation from a newly isolated Candida that showed a high lipase activity was subjected to examination of its reaction rate under various conditions. The original and a diluted enzyme solutions showed the zero order curve starting at the point of 50 minutes in time. When PVA was used as an emulsifyer more activity was observed than the case of gum arabic. The optimal temperature and pH were 37∼40℃ and 7.0, respectively. Oleic acid as a fatty acid conferred on the enzyme an inhibitory action while calcium ion a positive one. Sodium cholate yielded an increase in reaction rate at the first stage.

한국산 광대싸리(Securinega suffruticosa Rehder) 애서의 Securinine 추출

이춘영,이성환,안학수 한국농화학회 1965 Applied Biological Chemistry (Appl Biol Chem) Vol.6 No.1

1. The extraction of securine, an alkaloid, from Securinega suffruticosa Rehder growing in Korea was investigated. 2. The distribution of the source plant in Korea is considered to be most intense among the Fareast countries. 3. The extracted material was identified to be genuine securinine viewing from melting point and microscopic observation. 4. The yield of the substance in this study was 0.075% in average. The less amount of recovery may be due to the collection of the plant in October instead of that in the prime season. 5. There should be more efficient way in the separation of resinous impurities from the crude product. Application of Chromatographic technique and selection of more efficient solvent will be investigated hereafter.
