최문규,김회봉,조경식,서규환 한국독일어문학회 2000 독일어문학 Vol.11 No.-

Der Begriff "Medienrealita¨t" ist heute aktuell geworden. Obwohl die Medien zur Vemittlung der Kommunikation auch in der Vergangenheit sehr verallgemeinert worden sind, gelten sie heute nicht mehr als bloβes Mittel. Die Entwicklung der elektronischen bzw. technologischen Medien vera¨ndert sowohl die Realita¨t unserer Welt als auch das Sein schlechthin. Der Begriff "Medienrealitat" ist synonym mit den anderen Begriffen wie "digitaler Schein" bzw. "virtuelle Realita¨t". "Informationsgesellschaft", die den tradierten Gegensatz zwischen Sein und Schein. dem Wahren und dem Falschen auflo¨st und zu einer neuen "Form der Realita¨t" avanciert werden. Um die Medienrealita¨t zu analysieren. werden im zweiten Kapitel die verschiedenen Elemente illuminiert, durch die neue Medienrealita¨t und Kultur konstituiert werden: ganz neue "immaterielle Basis der Information. Macht der Bilder, Geschwindigkeit, neue computerielle Wahrnehmung. "Medienwerk". Diese Elemente beherrschen sowohl die Realita¨t als auch die Kultur. Abschlieβend wird die Mo¨glichkeit reflektiert. wie die Kunst (besonders die Literatur) die Medienrealita¨t u¨berwinden und ihre alternativen Wege ero¨ffnen kann. Im dritten Kapitel wird der Begriff "virtuelle Realita¨t" philosopisch uberpruft, wobei er die Gemeinsamkeiten mit den tradierten philosophischen Begriffen wie "dynamis, "potentia, "virtualite"~possibi1ite usw. teilt. Auch kann der Widerspruch der "virtuellen Realita¨t" besta¨tigt werden, die vor allem auf der radikalen Vera¨nderung von Technik. Information und Kapital basiert. Das heiβt: es ist ein Widerspruch oder die Verhu¨llung der ontologischen Implikation, daβ die virtuelle Realita¨t durch die allma¨hliche Negierung ihrer Virtualita¨t zur Realita¨t erhoben wird. Im vierten Kapitel wird das Verha¨ltnis der Gesellschaft zu Umwelt. Information und Medien aus der Sicht der Luhmannschen Systemtheorie betrachtet. Daraus ergibt sich. dass die Gesellschaft als Sozialsystem bei ihrer Selbstreproduktion mit der Leitdifferenz von System/Umwelt operiert und damit die elbstreproduktion der Gesellschaft von der Vera¨nderung ihrer Umwelt (Technik, Bewuβtsein, Organismus usw.) abha¨ngig ist. Dabei ist deutlich, dass Medien (Schrift. Buchdruck. Elektronik usw.). die zur Verbreitung der Informationen dienen, bei der Evolution der Gesellschaft eine entscheidende Rolle gespielt haben. Schlieβlich handelt es sich um die unterschiedlichen soziologischen Theorien u¨ber das Verhaltnis von Medien und Gesellschaft. In den Vordergrund treten dabei die Theorien von D. Bell und M. Poster. Bells Theorie der postindustriellen Gesellschaft behandelt die Entwicklung der Technologie. die heute die Kultur und die Gesellschaftsstruktur stark vera¨ndert. Gegen Bell postuliert Poster eine Wende von der Produktionsweise zur Informationsweise, indem er die erwandtschaft mit der postmodernen Theorie teilt. Seiner Perspektive zufolge gilt heute nicht das Kapital. sondern die Information als Hauptmovens der Gesellschaft. Die Medien ko¨nnen weder das Absolute noch die Utopie sein. Was der Euphorie der sog. "idealen Entwicklung der Medien" kritisch gegenu¨berstehen kann. ist nichts anderes als die kritische Reflexion der Kunst.

천연 포도과즙 발효용 식초산균 분리

최경호,정은희 대구효성가톨릭대학교 응용과학연구소 1998 응용과학연구논문집 Vol.6 No.2

포도과즙을 이용한 식초산 생산을 위하여 강한 증식력과 아울러 아황산 소다 및 poly phenol성 물질에 대한 내성을 지니고 산소 요구도가 낮은 발효균주가 요망되었다. 본 연구에서는 이러한 성질을 갖춘 우수한 식초산균을 분리하기 위하여 실험을 수행하였으며 탄산칼슘을 첨가한 ethanol배지와 포도과즙을 이용하여 여러 가지 재래초로부터 식초산균을 분리하였다. 분리균은 단간균 내지 타원형 세균으로 불규칙한 모양을 하고 있으며, 전체적인 모양은 대조군으로 사용한 Acetobacter aceti(KCTC 1010)와 비슷하였으나 크기의 차이가 있다. 분리균의 증식도는 대조균보다 현저히 빨랐으며 paper disc법으로 확인한 clear zone 생성능력(Acetic acid 생성 능력과 비례)은 분리균이 대조균보다 약 11%가 높았다. 분리균은 포도과즙을 산도 6.2%의 포도식초로 발효하였으며, 8일간의 발효과정중 pH는 3.8에서 3.5로 약간 저하되었다. HPLC분석에 따른 발효전과 발효 후의 유기산의 변화는 tartaric acid와 fumaric acid가 약간 증가되었으며, acetic acid는 약 2.5배 증가하여 전체 유기산의 90%이상을 차지하였고 총 유기산의 함량도 증가하였다. 이상의 결과로 본 실험에서 분리한 식초산균은 천연 포도과즙에서 빠르게 증식하여 고동도(6%이상)의 식초산을 생성할 뿐만아니라 pH와 색상의 변화가 적고 정치배양에도 잘 적응하는 우수한 포도식초 발효균으로 판정되었다. Experiments were carried out to isolate a bacterial strain for fermentation of alcoholic grape juice(low grade wine) to vinegar without any drastic changes in color of the products. Among eight strains of bacterium isolated from various sources, a bacterial strain was finally selected as the fermenting organism by using solid-ethanol medium. Cells of the bacterium were rod or ellipsoid-shaped. Microscopic morphology of the cells were very resembled to Acetobacter aceti(KCTC 1010) used as an control organism. The bacterium grew actively in grape juices after a lag phase for 2 hours, and produced acetic acid in accordance with it's growth. Wine vinegar containning 6.2% acetic acid and having typical flavor and color of grape fruit was produced by fermentation for 8 days. These results suggest that the isolated bacterium was an Acetobacter sp. and useful for fermentation of wine vinegar of good quality.

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jean. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'monitoring'. We used Likert's scale to assess the factor as a obstacle : 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-dont't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except 'lack of dietician's understanding about HACCP System(2.86±0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) 'Deficiency of hygiene facilities(4.41±0.76)', 'lack of teachers' cooperation(4.23±0.77)', 'inadequacy of the kitchen lay-out(4.19±0.95)' and 'lack of training and educating program for employees(3.97±0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.

Over the Past several decades blood and blood components have been increasingly, recognized as medication rather than innocuous fluids used to replace modest blood lose at operation. But blood transfusions have the potential for many harmful side effects. This study was undertaken to evaluate transfusion accordings to department, sex, preoperative hemoglobin values, blood type, transfusion amounts and blood component therapy. Of a total 34.906 operative cases, 5,793 patients who recived a transfusion during operation were analyze statistically at the Department of anesthesiology, chungnam National University Hospital from January 1985 to September 1992. The results were as Follows : 1) The numbers of transfused patient among the 34,906 operative cases were 5,793 cases (16.57%). 2) The number of male transfused was greater than of female and third decade patients was the greatest incidence among the transfused patients. 3) Mostly hemoglobin value in preoperative state was maintained more than 10 mg/dl (85.75%). 4) The blood types of transfused blood were in the great order of A, B, O, AB type. 5) The percentage of one pint transfusion was gradually decreased and 2~5 pints transfusion was greatest percentage (60.11%). 6) As the amount of blood transfused was increased, the percentage of blood component therapy was increased, and mixed case PRC and FFP was the greatest incidence (46.02%).

상아질에 대한 저점도 복합레진의 자가접착에 관한 연구

The objectiveness of this study was to evaluate whether low-viscosity composite can bond effectively to dentin surface without bonding resin. The low-viscosity composites being 50wt% filler content were made by the inclusion of bonding resin of two self-etching systems(Clearfil SE Bond, Unifil Bond) varied with contents as 0, 10, 20, 30, 40, 50wt%. Exposed dentin surfaces of extracted 3rd molars are used. Dentin bond strengths were measured. The tests were carried out with a micro-shear device placed testing machine at a CHS of 1mm/min after a low-viscosity composite was filled into an iris cut from micro tygon tubind with internal diameter approximately 0.8mm and height of 1.0mm. 1. Flexural strength and modulus was increased with the addition of bonding resin. 2. Micro-shear bond strength to dentin was improved according to content of bonding resin irrespective of applying or not bonding resin in bonding procedure, and that of Clearfil SE Bond groups was higher than Unifil Bond. 3. There were no significant difference whether use of each bonding resin in bonding procedure for S-40, S-50, U-50(p>0.05). 4. In SEM examination, resin was well infiltrated into dentin after primed with self-etching primer only for S-50 and U-50 in spite of the formation of thinner hybrid layer. Low viscosity composite including some functional monomer may be used as dentin bonding resin without an intermediary bonding agent. It makes a simplified bonding procedure and foresees the possibility of self-adhesive restorative material.

A promising application of Lactococcus lactis is its use as live vehicles for production and delivery of heterologous proteins of vaccines and therapeutic substances. Because L. lactis has GRAS ("generally regarded as safe") status, use tested whether L. lactis could function as the carrier of the L1 protein of human papillomavirus (HPV) type 16. The RNA level expression of L1 gene was detected in L. Laois. The L1 protein was expressed in L. luctis with LI gene. The growth of strains L. lactis with an empty plasmid (pAMJ328) and L. lactis with L1-encoding plasmid (pAMJ328-L1) was slightly decreased in comparison with the growth of strains L. lactis (wild type). However, all the three strains of L lactis maintained the ability to ferment sugars primarily into lactic acid, indicating that L1 protein did not affect the biochemical property of L.. lactis. These results suggest that L. lactis. capable of carrying LI protein, might he further developed as a biocompatible oral protein delivery system.
