The study investigated the serum lipid metabolism and enzyme activities of Korean teas for their preventative activity against chronic disease and obesity. Male Sprague-Dawley rats were raised for 8 weeks on four experimental diets: normal diet, hyperlipidemic diet, and hyperlipidemic diet to which green and black teas (2% each) were added. Various biological actions, including lipid metabolism and enzyme activities of the serum, were investigated. Diet-induced, hyperlipidemic rats fed with green and black teas, showed significant decrease in food efficiency ratio, triglyceride, total lipid, and phospholipid compared to control, i.e. the normal and diet-induced, hyperlipidemic rats. Total cholesterol, LDL-cholesterol, Al(atherogenic index), LHR, VLDL-cholesterol, ester-cholesterol, and free-cholesterol also showed a significant decrease. However, there was no significant difference between the tea-fed, diet-induced, hyperlipidemic dieted groups. HDL-cholesterol concentration was increased significantly in the tea-dieted and normal groups compared to the control. There was a little difference in lipase activity between the normal and control groups, although green and black tea-dieted experimental groups were both increased compared to the control. The contents of total lipid, triglycerides, and total cholesterol were decreased in the normal and experimental groups compared to the control. The GOT, GPT, ALP and LDH serum enzyme activities of the experimental groups were significantly reduced compared to those of the control groups.

정영희,모혜원,정지숙,최경호,최재갑,허윤경,이상흔,Jung, Young-Hee,Mo, Hye-Won,Jeong, Ji-Suk,Choi, Kyung-Ho,Choi, Jae-Kap,Hur, Yun-Kyung,Lee, Sang-Heun 대한안면통증구강내과학회 2009 Journal of Oral Medicine and Pain Vol.34 No.1

Recently there is much interest in the antibacterial activity of nano-sized silver particle (nanosilver) since silver is known to be safe and effective as disinfectant for a long time. Oral malodor is considered to originate in the oral cavity primarily as a result of production of malodorous compounds by oral bacteria. Major compounds responsible for oral malodor are volatile sulfur compounds, which is thought to be generated by the G(-) anaerobic bacteria found normally in the oral cavity, especially on the dorsum of the tongue. The purposes of this study were to investigate the effect of nanosilver on growth of oral malodor generating microorganisms, including Fusobacterium nucleatum, Prevotella melaninogenica, Klebsiella pneumonia, and to determine the optimal culture condition of them. The results were as follows: 1. The optimal culture condition for P. melaninogenica was vacuum culture using desiccator after evacuation of air by vacuum pump in chopped beef meat media. 2. The growth of K. pneumonia was temporarily inhibited by nanosilver (5 ppm and 10 ppm). 3. The morphological alteration and cell damage caused by nanosilver were observed in K. pneumonia.

독일 오디오 극의 교육적 재조명 - 독일 오디오 극 프로젝트를 중심으로

정영희 ( Jung Young Hee ) 한국독일어문학회 2020 독일어문학 Vol.88 No.-

이 글은 독일의 오디오 극 프로젝트를 통해 오디오 극을 교육적 시각으로 고찰하고자 한다. 청각만을 의존하는 청각 매체로서 오디오 극은 시각 미디어들의 등장과 함께 쇠락의 길을 걷는 듯 했다. 하지만 최근에는 인터넷을 바탕으로 오디오 극은 새롭게 변모 하였다. 독일학교에서의 오디오 극은 사회화 교육의 초석이 되며 청소년들을 위한 오디오 극 듣기와 협동 제작은 새로운 미디어 활용교육으로 떠오르고 있다. 도이췌 벨레가 이끄는 아프리카와 아프가니스탄에서의 오디오 극 프로젝트는 청소년들을 위한 사회교육과 민주주의 시민양성 교육을 위해 쓰이고 있다. 현재 오디오 극은 독일에서 주목받는 미디어로서 떠오르고 있으며 문학교육과 사회교육의 자료로서 활용되고 있다. 더 나아가 기술적 진보는 청취자와 제작자라는 경계를 허물어 청취자가 제작자가 되는 것을 용이하게 한다. 오디오 극이 이전에는 일방적인 미디어로 간주 되었지만 이제는 그 틀을 깨고 오디오 극의 새로운 역사를 쓰고 있으며 듣는 인문학의 재미를 더하고 있다. Durch die stetig größer werdende Konkurrenz der unterschiedlichen Medien schien die Bedeutung des Hörspiels lange Zeit rückläufig zu sein. In jüngerer Zeit lässt sich jedoch dank Internetgestützter Formate eine gewisse Renaissance des Hörspiels beobachten. An deutschen Schule haben die Perzeption und (Ko-)Produktion von Hörspielen eine immer wichtigeren Stellenwert in der Medienerziehung von Jugendlichen. Aktuell gelten Hörspiele in Deutschland als ausgesprochen interessantes Medium. In Afrika und Afghanistan werden unter Leitung der Deutschen Welle Hörspielprojekte im Jugendbereich für die soziale Bildung und für die Bekanntmachung mit demokratischen Prinzipien eingesetzt. Der technologische Fortschritt erleichtert einerseits den Zugang zu didaktisch wertvollem Material, andererseits lassen sich kreative Projekte unter Selbstbeteiligung der Lernenden unkompliziert realisieren. Nicht zuletzt kann es zusätzlich motovieren, Literatur nicht nur zu lesen, sondern auch zu hören.
