손석민,김인규,권윤중,변유량 연세대학교 산업기술연구소 1992 논문집 Vol.24 No.2

응집성 효모를 이용하여 추출 발효법을 개발하고자 내당 내알콜성 응집 효모인 Saccaromyces uvarum ATCC 26602를 사용하여 oleyl alcohol을 용매로 액-액 추출 발효를 행하였다. 그 결과 에탄올 저해 현상의 감소로 균체활성이 향상되었으며, 용매를 단속적으로 교환하여 줌으로써 배지중의 에탄올 농도를 40∼60g/L 범위를 유지하고 300g/L의 고당농도 배지를 공급하면서 계속적인 발효가 가능하였다. 그러나 용매의 분배 계수가 낮아 다량의 용매가 필요하였으며, 적절한 용매가 개발되면 효율적인 발효시스템으로 발전될 수 있을 것으로 기대된다. The process feasibility for continuous extraction of ethanol by oleyl alcohol form fermenting broths in batch or fed-batch cultures was studied. An immiscible organic solvent was introduced directly to the culture broth of flocculent yeast by bubbiling through the bottom porous sparger of a column fermentor. By continuously removing ethanol from the broth, cell activity was increased, and a concentrated feed medium containing 300 g/l glucose was successfully fermented. Operation of fed-batch extractive fermentation could be carried out for a long time by changing periodically the recycled solvent with fresh solvent.

濁氣의 病理的機轉에 對한 文獻的 考察

文錫哉 圓光大學校 韓醫學硏究所 1995 원광한의학 Vol.5 No.1

The turbid energy (zhuo qi, 濁氣) is the opposite conecpt of the clear energy (qing qi, 淸氣) and was mentioned firstly in Hwang Ti Nei Ching. Generally the turbid energy has the meaning of turbid part of food essence, dense and thick substance with the opposite meaning of turbid part of food essence, dense and thick substance with the opposite meaning of the clear energy, and cold, or dirty gas. Recently vital nutrient is regared as the clear energy and waste material as the turbid energy. In explaining the function of seperating the clarity from the turbity, the main function of small intestine in Oriental medicine, the clarity is considered as the essence of foodstuff and the turbidity as water and stool. This study is to clarify the concept and the function of the turbid energy and its influence on human body from the viewpoint of the function of seperating the clarity from the turbity in small intestine. After bibliographic study, the following conclusions were obtained: 1. The turbid energy is classifed into the phisiologic material such as stool, urine and turbid part of foodstuff and the pathologic material such as cold, water, waste gas and toxin in the intestine. 2. The turbid energy is discharged out of body through the series of function of the stomach to send digested food downward, seperation the clarity from the turbity in the small intestine, transfortation in the large intestine and energy transformation of the urinary bladder. 3. Dense and thick part of phisiologic turbid energy is transformed into the defensive energy(wei qi, 衛氣). 4. Pathologic turbid energy may cause systemic disturbance, especially gastrointestinal problems as vomiting, belching, abdominal distension and constipation.

생태주의 이론과 CEMP 모형에 바탕을 둔 다문화교실의 교수방법

박휴용,노석준 한국교육방법학회 2012 교육방법연구 Vol.24 No.2

본 연구는 다문화교실을 위한 교수학습의 원리와 그 방법론에 관한 하나의 시론으로써, 다문화교실의 성격을 논의하고, 생태주의 관점에서 다문화 교실환경을 이해함으로써 다문화교실의 핵심적 교수학습 원리로 ‘협력-배태-매개-참여’(CEMP) 모형을 제시하고자 한다. 아울러 이러한 CEMP 모형을 바탕으로 한 구체적인 교수학습 방법론으로써 교사와 학생들의 역동적인 상호작용을 독려하는 상호작용적 피드백의 방법론을 제시하고자 한다. 이를 위하여 본고는 다문화교실의 성공을 위한 요인으로 문화적 다양성에 대한 인식과 참조의 필요성, 학습기회의 형평성을 보장하는 것, 그리고 교사의 태도와 대응전략에 있어서의 근본적인 변화가 필요함을 강조하였다. 또한 다문화교실의 교수방법론으로써 기존의 개별화 교수법과 문화감응 교수법이 생태주의적 관점에서 어떤 관련성이 있는지를 논의하였고, 하나의 실천적인 방법론으로써 주류문화 학생들과 다문화 학생들의 교수형평성을 고려한 ‘상호작용적 피드백’법을 교수방법론으로 제시하고 있다. 마지막으로, 본 논문이 강조하는 다문화교실에 대한 생태주의적 이해가 교수학습이론과 실천에 주는 시사점을 논의하였다. This study initiates a discussion on the principles and methodologies for implementing successful multicultural classrooms. In doing so, this paper discusses three major characteristics of multicultural classroom, and proposes ecological perspectives to understand the idiosyncratic context and environments of multicultural classroom. Then, this paper suggests a participation model which consists of mediation, collaboration, participation, and embeddedness as four constructing principles. Finally, this paper provides three methodological approaches of practicing an effective instruction for multicultural classrooms; Differentiated Instruction, Culturally Responsive Pedagogy, and Interactional Feedback Approach for securing instructional counterbalance. The significance of the Participation Model for multicultural classrooms lies in the following three points. First, the leadership for learning belongs to students, rather than teachers; second, the interaction between students becomes maximized and contextualized learning of meaning is emphasized; and third, students will perceive that learning is the result of continuous experience, through which they can participate in and cooperate with the communities of inquiry. Discussions on these three methodologies are followed.

十全大補湯加味方이 抗癌化學治療劑의 抗腫瘍效果 및 腫瘍細胞의 lysosomal enzymes에 미치는 影響

李炯柱,文錫哉 한국전통의학연구소 1997 한국전통의학지 Vol.7 No.2

十全大補湯加味方과 抗癌 化學療法劑인 mitomycin C의 倂用投與와 관련된 寶驗을 施行하여 아래와 같은 結論을 얻었다. 1. Ascites form of Ehrlich carcinoma에 十全大補湯加味方抽出物과 mitomycin을 倂用投與한 結果 十全大補湯加味方 抽出物에 의하여 mitomycin C의 抗腫瘍倂效果가 약간 增加하는 경향을 보였으며,마우스의 平均 生存期間도 增加하였다. 2. Solid form of Ehrlich ascites carcinoma에서 十全大補湯加味方 抽出物과 mitomycin C를 倂用投與한 結果 單獨投與時 보다 抗腫瘍效果가 더욱 뚜렷하여 腫瘍의 크기를 顯著하게 減少시켰다. 3. Ehrlich ascites carcinoma cell의 lysosomal enzymes의 총 活性度는 mitomycin C의 單獨投興時 보다 十全大補瘍加味方 抽出物의 投與時 顯著하게 蒸加하였으며,mitomycin C와 十숲大補瘍加味方 抽出物을 倂用投與한 경우에는 더욱 顯著하게 增加하였다. 4. 十全大補瘍加味方 抽出淚으로 前處理時 NK細胞의 標的細胞와의 結合能은 물론 結合된 標的細胞의 融解能도 促進되었다. 以上으로 보아 十全大補瘍加味方 抽出物이 자체로는 顯著한 抗腫瘍效果가 없다고 할지라도 腫瘍을 發生시킨 마우스의 生存率을 增加시키고,抗癌化學療法劑인 mitomycin C의 細胞毒性 및 NK細胞의 活性度를 亢進시키는 것으로 思料된다. Mainly side effects of antitumor chemotherapy are fatigue, G-I trouble(such as vomitting, nausea, diarrhea) and reduction of medullary function etc. Differentiated from syndromes in oriental medicine, above symptoms are recognized to "Deficiency of both ki(vital energy) and blood". And SDT(Sipjeondaebotang) has been widely used in "Deficiency of both ki(vital energy) and blood". SDTG(Sipjeondaebotanggamibang) consists of SDT plus several herb medicines-these have antitumor effect and reduce chemotherapheutic side effect. This experiment was undertaken to study the effects of SDTG on chemotheraphy. The results obtained in this study were as follows: 1. Antitumor activities of the ethanol extract from SDTG(Sipjeondaebotang -gamibang) and MMC(Mytomycin) on ascitis form of carcinoma in mice is a little improved. Especialy mean survival times of the group of SDTG(200mg/kg) and MMC(O.1mg/kg) is improved over 50%. 2. When SDTG and MMC is administrated together, the weight of tumor is more decreased than MMC alone. 3. 'The effect of the ethanol extract from SDTG and MMC on the lysosomal enzymes in Ehrich ascites carcinoma cell are more significantly improved than MMC alone. 4. SDTG extract increases both NKcell conjugation and cyto-lysis against target cell. According to the above results it is recognized that SDTG increases the chemotherapheutic effect of MMC and the activity of NKcell.

Factors Influencing Primary and Secondary School Students’ Media Literacy and those Factors’ Degree of Influences: with a Main Focus on the Variables of Students’ Background, Personally Owned Kinds of Media, and Media Utilization Behaviors

Seak-Zoon Roh 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.12

This study employed the 2015 Korea Media Panel Survey conducted nationwide in order to examine primary and secondary school students’ media literacy, the variables of students’ background and the kinds of media devices that they own, utilization behaviors affecting their media literacy, and such variables’ degree of influence. To this end, data on 1,253 primary and secondary school students (884 households) were used. In order to analyze the data, SPSS 22.0 was used. Validity, reliability, and hierarchical regression analysis were also conducted. The analysis results showed that media literacy of primary and secondary school students was mostly high and the variables of students’ background and kinds of media devices and utilization explained 61.1% of media literacy variate. In particular, as the school level became higher, the place of residence changed from the county, small- and medium-sized cities to large cities, the kinds of Internet services utilized increased, and the more kinds of media devices that the students owned, their media literacy became higher. On the other hand, the greater the frequency of participation in Internet utilization was, the lower media literacy was. Meanwhile, the factor that most affected students’ media literacy was the level of school, followed by Internet service utilization kinds and resident districts. Based on such study results, this study presented specific measures aimed at increasing primary and secondary school students’ media literacy.
