Measurement and analysis of the physical status (height, body weight, breast girth, sitting height. length of leg, length of thigh, thigh girth, crural length, length of arm, brachial length, antebrachial girth and skinfold thickness), physical types and the growth were made to the 360 Korean middle and high school boys aged between 12 and 17 years in Taegu City. The physical status was evaluated and expressed as dispersion and the Physical type as percentage of each status to height, and the growth was analysed by the growth formula. The results are as follows; 1) The increase of the volumes of Physical status was slowest between 12 and 13 years and fastest between 13 and 14 years in general. 2) The increase of the volumes of thigh girth and antebrachial girth showed a linear pattern until 16 years. 3) The coefficient of variation was largest in skinfold thickness $(16.3{\sim}28.4%)$ followed by body weight $(10.0{\sim}14.3%)$, antebrachial girth $(4.8{\sim}19.60%)$ and length of thigh$(6.3{\sim}13.6%)$. The coefficients of variation in all the other status were similar $(4{\sim}7%)$. 4)The physical indices of body weight, breast girth, sitting height, length of thigh, thigh girth, antebrachial girth and skinfold thickness increased as age increased while the others decreased except the brachial length, which showed no significant change. 5) Ratio of growth quantity was largest in body weight followed by skinfold thickness, and the others were all similar. 6) Growth rate and specific growth rate decreased in the all the status analysed as age increased except in the skinfold thickness in which an increase was noted. 7) Growth gradient was increased along the increase of age in breast girth, sitting height, crural length, brachial length and in skinfold thickness. However a decrease was observed in the other status except in the body weight which was decreased until 15 years of age and increased thereafter.

어린 숭어 (Mugil cephalus)의 염분별 삼투조절 능력
이영춘,장영진,이복규,LEE Young Choon,CHANG Young Jin,LEE Bok Kyu 한국수산과학회 1997 한국수산과학회지 Vol.30 No.2
In order to investigate the osmoregulation capability of grey mullet, Mugil cephalus with the different salinities, juvenile fish $(13.6{\pm}0.2\;TL)$ stocked in seawater (SW) were abruptly transferred to each experimental group $0\%SW(0\%_{\circ}),\;25\%SW(7.7\%_{\circ}),\;50\%SW(16.1\%_{\circ})\;and \;100\%SW(32.8\%_{\circ})$ and reared for 60 days. Blood samples were taken by the time schedule after the transfer. Plasma $Na^{+},\;K^{+},\;Cl^{-}$ and osmolality, muscle water content, and the electron microscopical observations of chloride cells were analyzed and made by the time schedule. In $100\%SW$, the maintainable levels of plasma $Na^{+},\;K^{+},\;Cl^{-}$ and osmolality were $167.1{\pm}7.7mM/l,\;9.1{\pm}2.1mM/l,\;137.8{\pm}5.6mM/l\;and\;351{\pm}18\;mOsm/kg$, respectively. These values were significantly changed at $6h\~1\;day$ after the beginning of the experiment with four different salinities. Fish from $0\%\;and\;25\%SW$ had lower osmolalities than those of fish from $50\%\;and\;100\%SW$, and showed the hyposmotic regulation pattern. At the end of the experiment (60 days after transfer), however, no significant difference was found in the concentrations of plasma $Na^{+},\;K^{+}\;and\;Cl^{-}$ among four experimental groups. Hematocrit was increased with salinity (P<0.01). After 10 days, fish from $0\%\;and\;25\%SW$ showed the hypertrophy, fusion and edema of epithelial layer in gill lamella. However, at the 15th day, epithelial layer in gill lamella was back to the normal status. On gill of fish from $0\%SW$, one apical pit held two or three chloride cells in common. Muscle water content was subsequently regulated to near the normal levels within 4 days, and there was no significant difference among four different salinities at the end of the experiment.

가구디자인 공모전을 통한 가구산업 활성화 방안에 관한 연구 -경기 가구우수디자인 공모전을 중심으로-
이영춘,Lee, Young-Choon 한국가구학회 2006 한국가구학회지 Vol.17 No.2
In 1990s, with the rapid development of the design part and the change of perception, various design competitions in a way to encourage the design industry have repeatedly implemented and abolished. They played positive roles of developing designs and nurturing talents. On the contrary, they caused a lot of problems of standardization of design, loss of identification of competitions, deterioration of the quality of design. Especially, though too many competitions are holding, the level of quality cannot catch up with the quantity, resulting in numerous side-effects. In the field of Furniture Design, many competitions are just an one time events and disappeared. Therefore, it is very difficult to keep the tradition of prestigious competition, playing the adverse role in the development of furniture design and lowering the will of creativeness of designers. In this study, I compared and analyzed the current issues and problems of Gyeonggi Furniture Good Design Contest, one of the representative competition as the national scale competition as of 2006, with examples from home and abroad to find out the positive and developmental methods. At the same time, I provided the ways that can be helpful in the design through the ways to facilitate competition and proposals of desirable competitions.

Mammalian Sialyltransferase Superfamily : Structure and Function
이영춘(Young-Choon Lee) 한국생명과학회 2002 한국생명과학회 심포지움 Vol.38 No.-
To elucidate the regulatory mechanism for expression of sialylglycoconjugates and their biological functions, ninetheen sialyltransferase cDNAs including eleven by our group or co-works have been cloned and characterized so far. The cloned sialyltransferases are classified into four families according to the carbohydrate linkages they synthesize: α2,3-sialyltransferase (ST3Gal Ⅰ-Ⅵ), α2,6-sialyltransferase (ST6Gal Ⅰ), GalNAc α2,6-sialyltransferase (ST6GalNAc Ⅰ-Ⅵ), and α2,8-sialyltransferase (ST8Sia Ⅰ-Ⅵ). Each of the sialyltransferase genes is differentially expressed in a tissue-, cell type-, and stage-specific manner. These enzymes differ in their substrate specificity and various biochemical parameters. However, enzymatic analysis conducted in vitro with recombinant enzyme revealed that one linkage can be synthesized by multiple enzymes. We present here an overview of structure and function of sialyltransferases performed by our group and co-works. Genomic structures and transcriptional regulation of two kinds of human sialyltransferase gene are also presented.

송대(宋代) 이후의 『가례(家禮)』 연구와 조선(朝鮮)의 수용
李迎春 ( Lee Young-choon ) 한국계보연구회 2016 한국계보연구 Vol.6 No.-
The book Family Rite, Jiali 家禮, is usually called as Zhu Zi Jiali 朱子家禮 or Wengong Jiali 文公家禮, which is known that was compiled by Zhu Xi 朱熹(1130-1200) in 1170, during the southern Song Dynasty of China. However, this book has an unusual history. It was said to lost shortly after the writing, but was found again on the day of the death of the writer Zhu Xi in 1200. This book has many ambiguities in the writings and the handing down. So there was a lot of controversy about whether or not it was actually a book written by Zhu Xi. As the Family Rite was included in the Complete Collection of Neo-Confucianism 性理大全, which was compiled at the beginning of the Ming Dynasty, the authority became firm. However Wang Mao Hong 王懋竑(1668-1741), a Confucian scholar in the Qing Dynasty, criticized that this book was not the work of Zhu Xi. Anyway Many people of the world is still seen as the book of Zhu Xi. Since the first publication of the Family Rite by the Zhu Xi’s disciples, many commentators came out in China. There have been many translations and studies in Korea since the 16th century. Although there are many editions, the most common is a version in the Complete Collection of Neo-Confucianism and another one the Complete Library in Four Sections, Siku Quanshu 四庫全書. The latter is rather brief, but comparatively close to the original text. Though the former has many annotations, the system looks rather different from the original. Especially, the ritual images in the first volume are criticized much for the difference from the doctrines of Zhu Xi, the original auther. There are many bibliographic problems in the Family Rite. However, its simplicity, timeliness, universality, practicality, and consistency of contents have attracted considerable popularity. So it was widely used and utilized. Above all, the belief in the writings of Zhu Xi gave great authority to this book, especially in Korea. The Family Rite spread widely in Southern Song Dynasty after the death of Zhu Xi. At the time of the Yuan Dynasty, it spread throughout China and became the normative example in the gentry class community. It spread to neighboring countries and had a lot of impact, a big impact on Korea. At the end of the 14th century, the Family Rite was spread to Goryeo Dynasty of Korea. It contributed to making the Joseon Dynasty a Confucian society, and in the fifteenth century it became the normative example of royal ritual ceremonies and the gentry class society. In the early Joseon period, both the Family Rite and the Elementary Teachings, Shao Xue 小學, also the book of Zhu Xi, became necessary books for the candidates of officials as it became a required subject of the entrance examinations. Since the 16th century, studies on the Family Rite has been pouring out in Korea and translated versions have also been published, which made the Confucian rites spread into the lower class in Korea. Through the process, the Family Rite became the basis of Korean traditional ritual customs. It is necessary to study the book for the use of common people as well as the professional scholars.
