전통주 주박을 이용한 고부가가치 식품소재 개발을 위해, 상업적 시설에서 생산된 3종 약주(J-B, J-S, J-Y) 및 2종 탁주(J-H, J-W) 주박의 ethanol 추출물 및 열수 추출물을 조제하고 이들의 혈액응고 저해활성, 혈소판 응집저해 활성 및 인간 적혈구 용혈활성을 평가하였다. 5종 주박의 pH는 3.90~4.29로 유사하였으나, brix는 5.0~27.0으로 다양하게 나타났으며, 수분 및 알코올 함량에서도 시료에 따라 1.8배의 차이를 나타내었다. 주박의 색차와 성분은 첨가된 부재료 및 사용누룩에 좌우되었으며, J-W 주박의 경우 수분함량이 80.3%, brix 13, 알코올 함량 1.8%를 함유하여 다른 주박에 비해 다양한 식품제조에 용이하게 이용 가능하리라 판단되었다. Ethanol 추출효율은 J-H, J-W, J-B, J-S, J-Y의 순, 열수 추출효율은 J-S, J-B, J-W, J-H, J-Y의 순으로 높았으며, 총폴리페놀 및 총플라보노이드함량은 ethanol 추출물 중에서는 J-H, 열수 추출물 중에서는 J-Y 주박에서 가장 높았다. 5종 주박의 10종 추출물은 모두 5 mg/ml 농도까지 인간 적혈구에 대한 용혈활성이 나타나지 않았으며, J-B, J-S, J-Y의 약주 주박의 ethanol 추출물에서 유의적인 혈액응고저해 활성이 나타났으며, J-W 탁주 주박의 열수 추출물에서 thrombin 저해 활성과 J-B, J-S 및 J-H 주박 열수 추출물에서 혈액 응고인자 저해활성을 확인하였다. 혈소판 응집저해 활성평가의 경우 J-W 탁주 주박의 ethanol 및 열수 추출물에서만 아스피린에 필적하는 우수한 활성이 확인되었다. 본 연구결과는 다양한 약주 및 탁주 주박이 항혈전 활성을 가지고 있으며, 주박으로부터 항혈전제 개발이 가능함을 제시하고 있다. In this study, ethanol and hot water extracts of lees from Korean traditional wine (J-B, J-S, J-Y, J-H, and J-W) were prepared, and their effects on blood coagulation, platelet aggregation, and hemolysis of human red blood cells (hRBCs) were investigated to develop functional food ingredients from lees. The pH and brix of the lees ranged from 3.90 to 4.29 and 5.0 to 27.0o, respectively, and there was a huge difference in the water and ethanol content among the lees. The nuruk and additives used affected the color and physicochemical properties of lees. The J-W takju made from only rice and traditional nuruk, which has 13o brix and 1.8% of alcohol, has potential as functional food ingredient. With regard to the extraction yields of lees, higher yields were obtained from J-H, which contains different medicinal plants, in ethanol, followed by J-W, J-B, J-S, and J-Y. Higher extraction yields of lees were obtained from J-S in hot water, followed by J-B, J-W, J-H, and J-Y, respectively. The ethanol extract of J-H and the hot water extract of J-Y had the highest contents of total polyphenol and total flavonoids among the lees extracts. The 10 lees extracts did not show hemolysis activity against hRBCs up to 5 mg/ml. In an anticoagulation activity assay, the ethanol extracts of three yakju lees (J-B, J-S, and J-Y) and the hot water extract of J-W inhibited thrombin activity, whereas the hot water extract of J-B, J-S, and J-H inhibited blood coagulation factors. In an antiplatelet aggregation activity assay, only the J-W takju lees showed significant inhibition activity. Our results suggest that lees from traditional wine had high potential as a novel antithrombosis agent.

본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

본 연구는 이천석 목사의 부흥운동을 기도원운동, 회개운동, 성령충만을 위한 촉구, 그리고 치유사역을 중심으로 살펴보려 했다. 그는 청년시절, 6·25 동란에 참전 중에 한 다리를 잃고 절망 중에 자살을 하려고 여러 번 시도하였다. 또한 당시 상이용사에 대한 사회적인 냉대도 있었다. 그는 폭력단체를 조직하여 방탕의 삶을 살았다. 그러나 주님을 인격적으로 만나고 새로운 인생을 살아가게 되었고, 더 나아가 신학을 하게 되었다. 젊은 시절에 인생의 죄성을 철저하게 경험했던 그는 주의 일을 하면서 성령님의 도우심을 구하며, 금식하고 철야하며 부르짖고 기도했다. 따라서 그는 기도를 강조하며, 한국교회의 기도운동에 큰 영향을 끼쳤다. 그의 기도의 중요성에 대한 인식의 실천이 한얼산기도원이다. 또한 그가 설교 등에서 강조한 것은 회개와 변화였다. 그는 기도원에서 그리고 집회의 현장에서 회개운동을 펼쳐나갔다. 이러한 영적인 흐름은 한국교회에 영향을 끼치게 되었다. 또한 그는 성령충만을 강조했다. 물론 그는 방언이나 은사를 사모하는 자들에게 안수례를 했지만, 성령충만을 우선시했다. 기도원에서 그리고 집회에서 그는 성령충만과 부흥에 대한 열망을 촉구했다. 아울러 그를 통해서 치유의 역사가 강력하게 나타났다. 수많은 병자들이 치유를 받고 신앙에 더욱 매진했으며, 불신자들도 치유의 역사를 통해서 주님께로 나오는 계기가 되었다. 결국 이천석 목사의 사역활동에서 기도운동, 회개운동, 성령충만의 강조 및 치유의 활동은 곧 부흥운동이었다고 정리할 수 있다. 오늘날 예전보다 기도원이 축소되고, 그만큼 기도의 열기가 저조한 상황에서 다시금 이 땅에 부흥의 열망이 회복되기를 원한다. 이천석 목사를 비롯한 선진들의 영적자산을 공유하고 계승해 나가야 하리라 본다. 또한 성경공부 및 제자훈련과 함께 부흥운동이 균형적으로 전개 되었으면 한다. This paper researches pastor Chun Seok Lee’s revival movement, focusing on the prayer center movement, the repentance movement, the urging for the fulfilling of the Holy Spirit, and healing ministry. In his youth, he lost one leg during taking part in the Korean War. He organized a gang and lived a life of debauchery. However, He met the Lord personally and studied theology. He sought the help of the Holy Spirit while doing the work of the Lord, fasted, prayed all night long. He emphasized prayer and had a great influence on the prayer movement of the Korean church. The practice of his awareness of the importance of prayer is the beginning of Haneolsan Prayer Center. Also, what he emphasized in his sermons was repentance and change. These spiritual activities had influence on the Korean church.He also urged the desire for the fullness of the Holy Spirit and revival. In addition, through him, the miracle of healing appeared powerfully. So numerous sick people were healed and devoted more to their faith, and unbelievers came to the Lord. In the end, it can be concluded that the prayer movement, repentance movement, emphasis on the fullness of the Holy Spirit, and healing activities in pastor Chun Seok Lee’s ministry were revival movement. Today, prayer centers are decreased and the desire for revival is less than in the 1970s in Korea. I want all of us to restore the aspirations for revival in our land again. I think we must share and inherit the spiritual assets of pastor Chun Seok Lee and other advanced believers.

본 논문은 한국 근대수학교육의 아버지 이상설(李相卨, 1870-1917)이 자연과학―물리학―에 기여한 내용을 다루고있다. 이상설은 ?수리(數理)?를 쓴 시기를 전후하여, 같은 시기에 붓으로 총 8면에 걸쳐 『백승호초(百勝胡艸)』라는이름의 고전물리학 원고를 써서 남겼다. 분석결과 이 책의 원전은 1879년에 동경제대 의학부 교재로 발간된 『물리학(物理學)』이다. 이상설은 『백승호초』에서 먼저 개념을 정의하고, 일상에서 나타난 대표적 현상을 선록하여 한문으로번역하였고, 『물리학』의 전체 분량에서도 특히 ‘통유성(通有性)’에 중점을 두고 설명하였다. 동양에서 서양의 수리과학이 들어와야만 말할 수 있는 ‘질량보존의 법칙’, ‘타성(惰性, 관성)’과 같은 고전물리학의 중요개념을 포함하는 내용이 19세기 말에 이미 이 책에 소개된 것으로 보아 이상설은 당대의 다른 저술에서 보기 힘들 정도로 당시 일반물리학의 최고수준의 원서를 통해 최신 정보를 수용하고 전파하기 위하여 노력하였음을 볼 수 있다. Sang-Seol Lee(1870-1917) wrote a manuscript BaekSeungHoCho(百勝胡艸) in the late 19th century. BaekSeungHo-Cho was transcribed in classical Chinese from the 1879 Japanese book Physics(物理學) by Teizo Ihimori (1851-1916). Sang-Seol Lee, a famous independence activist, is also called Father of the Modern Mathematics Education of Korea,because of his early contribution to the modern mathematics education in the 19th century. In this paper, we introduce contents of his manuscript BaekSeungHoCho for the first time and discuss the significance of this book. Also, we show his constribution on the introduction to modern physics in the late 19th century Korea.

In 1895, They formed an organization around Lee Doh Chul and Im Choi Soo in revenge for Queen Myung-Sung who was assassinated by japanese killers (they called El-Mi-Oe-Ran) and the incarceration of Emperor Go-Jong, that is so called Chun-Sang Gate insurrection. The insurrection supporters assaulted through the Chun-Sang Gate of Kyung-Bock Palace was in vain, the leaders were arrested and a lots of participators condemned to death but it was the endeavor for a spirit of national salvation and a legitimate sovereignty. When Leaders of Chun-Sang Gate insurrection was arrested they would not implicate the King even though they moved by the terms of King's secrete Royal decree. They died chivalrously. After all Emperor Go-Jong bestowed Chung-Min Gong for the sake of his loyalty and ordered memorial service at Jang-Chung-Dan-Sa, So he was appraised appropriately at that time already.

J. H. LEE, Y. S. LEE. Kinematic Analysis of Double Backward Somersault on the Parallel Bars. Korean Journal of Sport Biomechanics, Vol. 14, No. 1, pp. 27-40, 2004. The purpose of this study was to provide basic data for improving athletic performances by analyzing the kinematic variables of the Double Backward Somersault on the Parallel Bars through the 3D motion analysis. The subjects in this study were 5 male gymnasts who were ranked as national athletes. The results are as follows. 1. A total time(Mean Time) of performance showed 2.72±0.82 sec. and flight time to landing after releasing was o.87sec.(mean). In order to perform better stable flying movement, the flight time should be increased. 2. In the change of velocity of the center of mass, when the increasing ascension velocity of the upper point was high, the position in the top point was high on releasing. 3. In the position variable of the center of mass, the mean of upper-bottom position in horizontal posture was 242.1±6.5cm, 232.8±6.4cm in releasing, and 265.0±5.6cm in the highest point. This result is explained that the position of center of mass can be raised by using elastic power when wrist raised the bar in the releasing movement. 4. The angle of shoulder joint was 271.1±14.0. Such a big angle influences a negative effect on the releasing velocity, because trunk is not a position in the enough vertical direction. 5. The ankle of hip joint in hand-standing was 191.1±5.9, 118.8±5.3 in releasing, and 122.3±5.3 in taking on. Therefore, the result suggests that trunk should be straightly raised in taking on.

Dr. Jae Sik Lee. 1999. Brighter Linguistic Society. Collected Papers on Cristian Language Culture. Language is to help make humans human in worldview, culture, and society. Human language is to make society brighter. And brighter language makes it possible for us to establish brighter society. On the basis of brighter language in brighter society, we should establish a new human society of morality which all of us humans aspire for and which can be found in the Bible. Based on these arguments, this paper makes an introductory remark in chapter 1. In chapter 2, this paper argues about worldveiw, culture, and society. In chapter 3, brighter society and human language, and in chapter 4, dark language and brighter language are argued in succession. In chapter 5, this paper proposes that moral society is to be established by brighter language activity, Finally, in chapter 6, this paper also proposes that a new human society of morality which all of us humans in the New Millennium aspire for should be established on the basis of brighter language in brighter society.

This study intends to test the effect of cyber victimization on cyber offending and investigates which variables operate moderating effects. This study uses six moderating variables such as low self-control, attitudes toward cyber delinquency, parental support, peer support, self-esteem, and the perceived opportunity of cyber delinquency. Using data from 353 elementary, middle, and high school student in Kyunggi area, the study tests the interaction effects of cyber victimization and moderating variables on cyber offending. Results show that the interaction effect between cyber victimization and low self-control is not significant. However, the interaction effect between cyber victimization and attitude towards cyber delinquency is positively significant. In addition, the interaction effect between cyber victimization and peer support is negatively significant, while the interaction effect between cyber victimization and parental support is positively significant. It is also found that the interaction effect between cyber victimization and self-esteem is negatively significant. It is revealed that the moderating effect of the perceived opportunity is the most significant. The policy implications are discussed.
