Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

It has been generally known that smoking is one of the worst factor increasing disease and mortality in human health since in 1950's and nowadays. But regardless of various proofs about social or economical problems due to smoking, current smoking rate has not been decreased in our country. Until now, most of tobacco use and its addiction researches have been focused on the adolescent or adult women smokers not on the university students. Therefore, the purpose of this study was to investigate smoking cessation of university smokers and analyze the health belief-perceived sensitivity, severity, benefits and barriers- difference, then to provide basic data for effective smoking cessation strategy for university smokers. The subjects were comprised of 181 university smokers from 15 universities in Seoul. The data were collected by structured questionaires. The questionaires were designed to measure general characteristics, smoking cessation and health belief, based on Ahn(2003)'s result on the Study of Smoking attitude, Behavior and Smoking Cessation of Adult Male and Lee(1987)'s result on Relationships Between the Health Belief Model and Smoking Habits. The data were collected from May 5 to 16. The collected data were analyzed by SPSS program. The actual number, percentiles, means, standard deviation, t-test and ANOVA were done. The result of this study were as follows; 1. The general characteristics of the subjects of this study The range of age was from 18 to 34 and the averaging age was 23. The subjects of this study were 141 males and 40 females. The religions were Christianity 25.4%(46), Buddhism 12.7%(23), Catholic 23.2%(42), no religion 37.0%(67). The residential forms were living with family 59.1%(107), cooking food for oneself 28.7%(52), dormitory 5.0%(9), boarding house 1.7%(3). Smoking starting age were university 43.1 %(78), high school 29.8%(54), middle school 14.9%(27), in the army 6.1 %(11), elementary school 1.1 %(2). 2. The smoking cessation of the subjects 80% of current smokers showed quitting smoking decision and 20% have not tried. The frequency of quitting smoking decision were from 1 to above 8 and mean was 3.06. As for smoking cessation plan, 54.7%(99) current smokers answered yes, 3.9%(7) said no, 35.4%(64) had no idea and 6.1 %(11) didn't answer. As for the reason of never quitting smoking decision, 71.42%(25 among total 35) have no need to quit smoking and the others said difficulty of smoking cessation. As for the main reason of smoking cessation decision, 54.7%(99) answered for the health, 7.2%(13) family advice, 15.5%(28) girl/boy friend's advice, 1.7%(3) to save money. As for the reason to fail smoking cessation, 56.7%(68) were will-lack, 17.5%(21) stress, 15%(18) smoking mood, 10%(12) withdrawl symptom. As for the smoking cessation method, 85.0%(125) were oneself-will, 2.7%(4) way acquired by mass-media, 2%(3) doctor's prescription, 2%(3) religion's help, 0.7%(1) smoking cessation school. As for the difficulty in smoking cessation, 42.2%(62) were drinking meeting, 23.1 %(34) no alternative of stress release, 12.2%(18) withdrawl symptom, 11.6%(17) having nothing to do, 7.5%(11) friend's encouragement. As for the most difficult cigarette to quit, 67.8%(99) were all-day smoking except the first smoking in the morning, 32.2%(47) the first smoking in the morning. 3. Health belief as for general characteristics Gender - The total point in benefits showed higher in male(28.5177) than female(26.6750). There was significant difference(t=.778, p<.05). The total point in health belief showed higher in male (105.8298) than female(l00.5000). So there was significant difference(t=.345, p<.05). Age - There was significant difference in benefits between age(10's-25.83, 20's-28.39, 30's-32.00)(F=3.73, p<.05). Smoking starting age - There was significant difference in total point of sensitivity and health belief(sensitivity F=4.00, p<.Ol, health belief F=2.843, p<.05). As for sensitivity, subjects who started smoking in the army showed the highest(33.36) and ones in high school showed the lowest(26.96). The total point in health belief showed the highest in elementary school(l19.00) and the lowest in high school(100.98). 4. Health belief as for smoking cessation There was significant difference in health belief as for smoking cessation(t=0.189, p=0.OO2). Sensitivity point showed higher in smoking quitting trial smokers(29.2) than non-trial smoker (26.9). Severity point showed higher in trial smokers (30.7) than non-trial smokers(28.9). Benefit point showed higher in trial smokers(28.6) than non-trial smokers(26.2). There was no significant difference in barriers point.

This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150±15g, were randomly assigned to 5 groups: basal diet only in normal control group(NCG); basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3㎎/㎖) injection in heavy metal low duck juice group(HMLD), basal diet, heavy metals and DJ(30㎎/㎖) injection in heavy metal middle duck juice group(HMMlD); basal diet, heavy metal and DJ(300㎎/㎖) injection in heavy metal high duck juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation m tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

이혜원,최호정,김명철,정성목 忠南大學校 獸醫科大學 附設 動物醫科學硏究所 2009 動物醫科學硏究誌 Vol.16 No.1
A 5-year-old German Shepherd dog(intact male, 27kg) was admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of anorexia and vomiting. On physical examination, he was depressed and had abdominal distention. A complete blood count indicated leukocytosis and anemia. Radiographic findings included a large soft tissue mass in the middle to caudal abdomen and loss of serosal detail. Ultrasonographs showed splenomegaly with mixed ethoic parenchyma, hyperechoic area around the splenic hilus, and loss of venous flow. Computed tomography revealed enlarged spleen with partially enhanced parenchyma. Chronic isolated splenic torsion was diagnosed and splenectomy was performed. Histopathologic examination revealed chronic passive congestion of the spleen. He was recovered normally after surgery without any complications.

본 연구의 목적은 치면열구전색제 수복시에 상아질 접착제의 primer 도포의 치면열구전색제 열구 침투도 향상 효과를 확인하는 것으로 발거된 영구 구치상에서 통상적으로 치면열구 전색제를 도포한 대조군과 Scotchbond™ Multi-Purpose system과 ?? 2 system의 primer 도포 후에 치면열구전색제를 도포한 실험군들의 열구 기저부까지 전색제 침투 성공률을 비교하여 다음과 같은 결론을 얻었다. 1. Scotchbond™ Multi-Purpose system과 All-Bond 2 system의 primer를 사용한 군의 열구 기저부까지 치면열구전색제 침투 성공률은 primer를 사용하지 않은 대조군보다 높았으나 통계학적으로 유의성 있는 차이는 없었다(p>0.05) 2. 열구 깊이와 폭 및 '깊이/폭' 값은 열구 기저부까지 전색제 침투성공율에 대하여 통계학적으로 유의성 있는 효과를 나타내었다.(p<0.05) 3. 열구 기저부까지 전색제 침투 성공률은 열구 깊이가 25㎛ 증가할 때마다 약 0.9배로 감소하였고, 열구 입구의 폭이 25㎛ 증가할 때마다 약 1.1배로 증가하였으며, 열구의 '깊이/폭' 비율이 1 증가할 때마다 약 0.6배로 감소하였다. The objective of this study is to confirm the effect of dentine bonding primer application on penetration of sealant. Extracted permanent molars were used to compare penetration success rate of control group (sealant application only) and experimental groups (sealant application after applying the primers of Scotchbond™ Multi-Purpose system and All-Bond 2 system). The following results were obtained: 1. The experimental groups using the primers showed increased sealant penetration success rate to the base of fissure when compared to control group but there was no statistically significant differences(p>0.05). 2. The depth, width and 'depth/width' value of fissure had statistically significant effect on sealant penetration success rate(p<0.05). 3. The penetration success rate decreased about 0.9 times as the depth of fissure increased every 25㎛, and increased about 1.1 times as the width of the fissure orifice increased every 25㎛, and decreased about 0.6 times as the 'depth/width' value increased every 1. From the above results, it can be concluded that fissure morphology had a great effect on sealant penetration and for better penetration, use of dentine bonding primer can be helpful but it needs more study in clinical bases.

갈색거저리(Tenebrio molitor)複眼에 관한 微細構造的 硏究
이혜원,정문진,문명진 단국대학교 1997 論文集 Vol.31 No.-
Tenebrio molitor, adult beetle has one pair of comound eye not ocelli in head. This eye is dumbbell shape through dorsal to ventral direction in side of head. The compound eye is composed of about 300 ommatidia. An ommatidium consist of a lens, 4 Semper cells, 2 primary pigment cells, 90 secondary pigment cells, and 8 retinula cells. Light enters from the top and passes through the lens and Semper cells. The lens is biconvex type and lamellated. And then the Semper cells were observed below the lens. The cytoplasm of the primary pigment cells(PG1) is more electron density than Semper cells. Electron dense of pigment granules distributes along the proximal region of the cell. Secondary pigment cells(PG2) is peripherally located each ommatidium. The columnar secondary pigment cells have 2 different types pigment granules. One type(PG1) is electron dense and 0.6 ㎛ in diameter and another type(PG2) is less electron dense and 1.4 ㎛ in diameter. Retina is located under the Semper cells and is composed of 8 retinular cells. Among the 8 retinular cells 2 cells lie central area and the rest 6 cells is located peripheral region. It is morphological feature that rhabdom is formed by the partial fusion of 6 rhabdomeres and fully fusion of 2 rhabdomeres in Tenebrio molitor.
