최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

배기선,유권,조유경,심기남,정성애,문일환 대한간학회 2004 Clinical and Molecular Hepatology(대한간학회지) Vol.10 No.2

목적: 알코올성 간질환에서의 대사성 산증은 지속적인 과량의 알코올 섭취로 인한 당 신생 합성의 억제와 BOHB/AcAc 비율의 증가, 단기간의 금식으로 인한 저혈당, 인슐린 분비 저하, 유리 지방산과 케톤체 형성의 증가, 구토와 수분 섭취 부족에 의한 심한 탈수에 의해 발생하는 것으로 알려져 있다. 알코올성 케톤산증과 감별할 질환으로는 당뇨병성 케톤산증, 젖산증, 살리실레이트, 메탄올, 에틸렌글리콜 중독 등이 있다. 본 연구는 대사성 산증을 동반한 알코올성 간질환으로 내원하여 입원한 환자들을 대상으로 생존군과 사망군에서 임상적 양상 및 검사 소견들의 차이를 비교하여 단기 예후와 연관 있는 인자들을 알아보고자 하였다. 대상과 방법: 만성 알코올 남용자이면서 대사성 산증을 동반하여 입원한 알코올성 간질환 환자 29명을 생존군(18명)과 사망군(11명)으로 나누어 임상 소견과 검사실 소견을 비교하였다. 결과: 1) 대상 환자군은 연령은 36-65세였으며, 성별은 남자가 26명이었고 여자가 3명이었다. 2) 임상 증상은 의식저하, 복통, 구토, 호흡 곤란, 토혈, 흉통 등 다양하게 나타났으며, 신체검사 소견은 탈수, 황달, 빈혈, 간비대, 복수, 부종 등이었고 두 집단을 비교했을 때 사망군에서 복수가 유의하게 더 많은 빈도로 관찰되었다. 일일 평균 음주량은 사망군에서 유의하게 더 많았고(198 vs. 123, P=0.034) 음주 기간과 총 음주량은 두 군 간에 유의한 차이를 보이지 않았다. 4) 내원시 혈액검사 소견을 비교하였을 때 사망군에서 동맥혈 산염기 차이가 유의하게 낮았고 헤모글로빈, 혈소판도 유의하게 낮았다. 사망군에서 총 비리루빈, 크레아티닌, 무기인, 암모니아가 유의하게 높았고 알부민, 클로라이드가 유의하게 낮았다. 사망군에서 프로트롬빈 시간이 유의하게 연장되었으며 섬유소원은 유의하게 낮았고 D dimer는 유의하게 높았다. 결론: 대사성 산증을 동반한 알코올성 간질환 환자에서 일일 알코올 섭취량을 파악하고 복수의 유무, 동맥혈 산염기 차이, 헤모글로빈, 혈소판, 총 빌리루빈, 알부민, 크레아티닌, 무기인, 클로라이드, 암모니아, 프로트롬빈 시간, 섬유소원, D dimer 등을 검사하는 것이 단기 예후를 예측하는 데 도움이 될 것으로 사료된다. 향후 많은 환자들을 대상으로 하여 예후 관련 인자들에 대한 전향적이고 체계적인 연구가 요망된다. Background/Aims: Alcoholic liver disease with metabolic acidosis may have possible causes such as alcoholic ketoacidosis, diabetic ketoacidosis, lactic acidosis. Salicylate, methanol, and ethylene glycol intoxication should also be considered. The aim of this study was to investigate the short-term prognostic factors in patients with alcoholic liver disease with metabolic acidosis. Methods: Clinical data related to twenty-nine patients with alcoholic liver disease and metabolic acidosis was analysed retrospectively. Patients were divided into two groups according to the outcome (survival or death). Past medical history, and physical, laboratory and radiologic data at admission were compared. Results: The amount of daily alcohol intake differed significantly between the two groups (P=0.034), but duration and total amount of alcohol intake did not differ significantly between the two groups (P=0.128; P=0.360). The presence of ascites differed significantly between two the groups (P=0.019). On laboratory testing, the following differed significantly: base excess (P=0.038), hemoglobin (P=0.019), platelet (P=0.040), total bilirubin (P=0.007), albumin (P=0.012), creatinine (P=0.014), phosphorus (P=0.021), chloride (P=0.010), ammonia (P=0.003), prothrombin time (P=0.033), fibrinogen (P=0.011) and D-dimer (P=0.024). Review of the medical history of the patients showed diabetes (10/29), cirrhosis (10/29), and hepatocellular carcinoma (1/29). Combined conditions at admission were sepsis (8/29), pneumonia (7/29), acute renal failure (6/29), rhabdomyolysis (5/29), gastrointestinal hemorrhage (4/29), acute pancreatitis (3/29), acute respiratory distress syndrome (2/29), and acute myocardial infarction (1/29). Conclusions: The amount of daily alcohol intake, base excess, hemoglobin, platelet, total bilirubin, albumin, creatinine, phosphorus, chloride, ammonia, prothrombin time, fibrinogen and D-dimer seemed to be useful parameters in predicting short-term prognosis of patients with alcoholic liver disease with metabolic acidosis. Further study is needed to define the significance of these factors. (Korean J Hepatol 2004;10:117-124)

독일 연방군의 변화와 활동 추세

배안석,김유성 동아대학교 독일학연구소 2005 獨逸學硏究 Vol.- No.21

15 Jahre nach der deutschen Wiedervereinigung bei den Deutschen in Ost und West herrscht ein Bild von der Wundeswehr vor, das in weiten Teilen positiv aufgenommen ist und das den deutschen Landsleute Vertrauen gibt. Zum Teil kommen kritische Stimmen zur Bundeswehr bereits seit längerer Zeit aus den Reihen der jungen Bevölkerung. Aber die meisten deutschen Leute denken daran, dass die Bundeswehr für die Bevölkerung positiv tätig ist. Besonders ist die Haltung auch der jungen Generation zu den deutschen Streitkräften positiv geworden, nachdem die Bundeswehr z.B. bei der Unwetterkatastrophe geholfen habe. Seit 1990 wurde die Bundeswehr in die vielen Krisenregionen eingesetzt. Die Bundeswehr spielte und spielt eine Rolle als Gruppe für humanitäre und medizinische Hilfe. Auβerdem wurden einige Operationen von der Bundeswehr für die Unterstützung der Mission der multinationalen Streitkräfte gemacht. Zur Zeit sind rund 100.000 Soldaten der Bundeswehr in den Krisenregionen eingesetzt. Die Bundeswehr wurde seit ihrem Bestehen nach der Wiedervereinigung nachhaltig verändert. Dadurch kann sie erfolgreich bei der Hilfe für Frieden und Krisenbewältigung im In-Ausland tätig sein. Zukünftig wird die Zahl der Streitkräfte der Bundeswehr auf 200.000 reduziert. Dies beruht auf die Militärstruktur, die in der Zukunft verändert werden soll. Denn die Bundeswehr hat den Plan, die Struktur der drei Teile der Streitkräfte zu verändern in Sicherheitskräfte, Unterstützungskäfte und Stabilisierungskräfte.

유재하,이지웅,백성흠,정원균,김종배 大韓顎顔面成形再建外科學會 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.6

The purpose of this article is to confirm the longterm biocompatibility of national Avana implant and international ITI implant in dogs. At the fourth month after extreaction of the mandibular third and fourth premolar in three dog, both implants were inserted using careful atraumatic technique and prosthetic abutments were applied onto the implants in three months. After that, the implants were examined by naked eye and radiographic image every three months during 1 year, for detection of the complications, such as, mobility, bone resorption and wound infection. At 1 year after application of prosthetic abutment, the dogs were sacrificed for the histopathologic analysis by light microscope. The results obtained were as follows; 1. All implants had the ralatively good prognosis without mobility, wound infection and moderate bone resoprtion, in clinical and radiological evaluation during one year. 2. The all histopathologic specimens at one year after application of prosthetic abutment onto the implants showed the distinct osseointegration between implant system and bone, with projection of new bone apposition onto the peri-implant tissue. But Avana implants had the less osseointegration than ITI implants in the cancellous and marrow layer of jaw bone. 3. The all histopathologic specimens at one year after application of prosthetic device showed the firm junction by dense connective tissue pattern between the implant and the gingival portion. But Avana implants had the less firmer junction than ITI implants. 4. The authors confirmed that Avana implant and ITI implant have more higher tissue biocompatibility in dental implantation, but ITI implant has the more osseointegration than the Avana implant.

Great lateral forces arise commonly on retaining wall, piers and bulwark in harbours, bridge abutments and tower structure. Earth pressure dynamic forces(impact of ships), or wind pressure may be named as typical causes for these forces. This paper based on a series of model tests was performed to proposal the decision method of a allow lateral resistance of single pile under lateral load. Model tests were performed in changing of relative density. The model piles were made of copper tube, and the homogeneous model grounds were used air-dried fine sand enough to get through t.4 sieve. A summary test results were analyzed through the experiment as follows. The allow lateral resistance of the proposal method was larger than existing method as safety factor was applied two, that of the existing method was larger than proposal method as safety factor was applied three. But The allow lateral resistance was same to proposal method and existing method as safety factor was applied 2.5.

유중배,방효원,엄대용,이상돈 중앙대학교 의과대학 의과학연구소 1990 中央醫大誌 Vol.15 No.1

Effects of vanadate on the resting membrane potential and slow waves of the circular smooth muscle were observed using glass capillary microelectrodes. The obtained results were as follows: 1. Vanadate did not show any effects on; the slow waves of spontaneously beating preparations. 2. Variation of the resting membrane potential due to the change of outside K^+ was 20-28m V/decade which suggested the significant contribution of Na^+ to maintain the resting membrane potential. 3. Vanadate did not show any further effects on the depolarized state about l0mV by outside 20mM K^+. 4. Vanadate induced the depolarization in the low outside K^+ condition and the effect was exaggerated when Cal^(2+) was depleted. 5. Vanadate induced the depolarization in the low Na^+ and K^+ condition. It was conjectured that the effects of vanadate were enhancing the voltage-dependent calcium.

H9c2 심근 세포주에서 외인성 nitric oxide가 허혈에 의한 세포 독성에 미치는 영향

정성구,장현용,김명천,고영관,정주호,배영미,박원서,김대중,유영민,김성수,임성빈 대한응급의학회 2001 대한응급의학회지 Vol.12 No.4

Background: Nitric oxide(NO) is known to have protective effects on an ischemic heart and to exert triggering effects on ischemic preconditioning. However, the effects of NO during the ischemic period have not been investigated. To investigate the role of exogenous nitric oxide in a model of ischemic heart cell death, we studied the effects of ischemic preconditioning and ischemia in a normal and an ischemic buffer. Methods: Rat cardiac myoblast cells(H9c2) were cultured in a normal and an ischemic buffered medium. For the ischemic culture of heart cells, the cells were cultured in a dessicator with GasPak for 5 hrs. In ischemic preconditioning, the cells were pretreated with ischemic buffer for 5 min and then perfused with normal medium for 30 min. For the measurement of the cytotoxicity, a MTT(3-4-Sdimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide) assay was performed. A DAPI(4',6-diamidino-2-phenylindole dihydrochloride) staining procedure and a flow cytometry analysis were performed to confirm apoptotic cell death by ischemia. Results: Cell viability, as determined by using a MTT assay, showed that the preconditioned group treated with NO showed more cell death than with the not-preconditioned groups in both normal and ischemic buffers. But, In normal medium and not-preconditioned groups, NO showed protective effect according to the concentrations(100,1000μM) . No treatment with NO produced the different results. In normal medium, the protective effect of ischemic preconditioning was demonstrated, but no protective effect of ischemic preconditioning could be seen in the case of the ischemic buffer. The DAPI staining and flow cytometry analysis of heart cells showed characteristic apoptotic features. Conclusion: NO added in the ischemic phase had deterious effects on heart cells. Ischemic preconditioning was more harmful than ischemia alone. The toxicity of the cells was characteristic apoptosis.

사회극놀이가 자폐성 아동의 사회성에 미치는 효과

김유,최상배 한국특수아동학회 2003 특수아동교육연구 Vol.5 No.1

본 연구의 목적은 사회극놀이가 자폐성 아동의 사회성 증진에 미치는 효과를 알아보는 것으로 2명의 자폐성 아동을 연구대상으로 단일 사례연구법을 실시하였다. 그 결과 첫째, 사회극놀이 프로그램이 자폐성 아동의 사회적 책임감에 긍정적인 효과를 가져왔다. 둘째, 사회극놀이 프로그램이 자폐성 아동의 자기 주장에 긍정적인 효과를 가져왔다. 셋째, 사회극놀이 프로그램이 자폐성 아동의 친 사회적 신체 자세 변화에 긍정적인 효과를 가져온다는 결론을 도출하였다. 이는 자폐성 아동의 사회적 상호작용의 향상에 더 효율적인 방법이 언어적 훈련이 아니라 놀이 훈련이라는 선행연구의 결과와도 일치하고 지능이나 언어적 능력보다는 자폐성의 장애 정도와 사회적 자립과 관련이 있다는 결과와도 일치한다. 그러므로 이 프로그램은 경증의 자폐성 아동에게 더 효과적이라고 볼 수 있다. 단, 자기 주장과 관련된 사회성 기능은 다소 차이를 보였는데 이는 언어적 능력을 더 요구하는 항목이므로 약간의 차이를 보인 것으로 보인다.
