Background/Aims: Identification of patients at high risk for perioperative cardiac events (POCE) is clinically important. This study aimed to determine whether preoperative measurement of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) could predict POCE, and compared its predictive value with that of conventional cardiac risk factors and stress thallium scans in patients undergoing vascular surgery. Methods: Patients scheduled for non-cardiac vascular surgery were prospectively enrolled. Clinical risk factors were identified, and NT-proBNP levels and stress thallium scans were obtained. POCE was the composite of acute myocardial infarction, congestive heart failure including acute pulmonary edema, and primary cardiac death within 5 days after surgery. A modified Revised Cardiac Risk Index (RCRI) was proposed and compared with NT-proBNP; a positive result for ischemia and a significant perfusion defect (≥ 3 walls, moderate to severely decreased, reversible perfusion defect) on the thallium scan were added to the RCRI. Results: A total of 365 patients (91% males) with a mean age of 67 years had a median NT-proBNP level of 105.1 pg/ mL (range of quartile, 50.9 to 301.9). POCE occurred in 49 (13.4%) patients. After adjustment for confounders, an NTproBNP level of>302 pg/mL (odds ratio [OR], 5.7; 95% confidence interval [CI], 3.1 to 10.3; p<0.001) and a high risk by the modified RCRI (OR, 3.9; 95% CI, 1.6 to 9.3; p = 0.002) were independent predictors for POCE. Comparison of the area under the curves for predicting POCE showed no statistical differences between NT-proBNP and RCRI. Conclusions: Preoperative measurement of NT-proBNP provides information useful for prediction of POCE as a single parameter in high-risk patients undergoing noncardiac vascular surgery.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

The purpose of this study was to investigate the effect of exercise to mentally retarded women's bone mineral density. Subjects were divided into three groups: Group A(age:27.9yr, n=8)-This group was mentally retarded exercise women, who had been doing regularly exercise for over three years. Group B(age:28.8yr, n=8)-This group was mentally retarded non exercise women, who hadn't been doing it as usual. Group C(age:29.0yr, n=8) This group was normal women, who hadn't been doing it as usual. This study analysed and compared the bone mineral density between these three groups. The results were summarized as follow. 1.The BMI of group A(Mentally retarded exercise group) was 22.8±3.28 kg/m2, group B(mentally retarded non exercise group) was 22.6±5.6 kg/m2, and Group C(normal group)was 22.0±2.2 kg/m2. There were no significant differences in BMI between three groups. 2.There were significant difference in grip strength and back strength between three groups(p〈.001). The grip strength of group A was 16.9±6.5 kg, group B was 12.2±4.0 kg, and group C was 31.8±2.1 kg. The back strength of group A was 36.9±16.1 kg, group B was 34.2±8.4 kg, and group C was 96.9±32.7. 3.These were significant difference bone mineral density of lumbar between these groups. Group A was 0.1±0.08 g/cm2, Group B was 0.888±0.10 g/cm2, and group C was 1.05±0.04 g/cm2(p〈.01). 4.These were very significant difference bone mineral density of femur between these groups. Group A was 0.91±0.09g/cm2, group B was 0.74±0.08 g/cm2, and group C was 0.97±0.14 g/cm2(p〈.0001). 5.These were very significant difference bone mineral density of Forearm between these groups. Group A was 0.6±0.02 g/cm2, group B was 0.56±0.03 g/cm2, and group C was 0.63±0.02 g/cm2(p〈.0001). 6.Group A were correlations between bone mineral density of femur(neck) and BMI, weight(p〈.05). 7.Group B were correlations between bone mineral density of forearm(MID, total) and age(p〈.05). 8.Group C were correlations between bone mineral density of lumbar(L1) and age, BMI, back strength(L4).

수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

'친일시'의 생명 유지 장치

최지현 배달말학회 2003 배달말 Vol.32 No.-

그간 '친일시'에 관한 제담론들이 문학적 담론으로 기능하지 못한 결과 역설적으로 '친일시'의 생존 조건이 지속적으로 마련되어 왔다. '친일시'를 역사적, 또는 정신사적 차원에서 다루게 되는 경우, 그것이 독자의 정서와 상상체계에 미치는 부적절한 교육적, 문학적 영향들이 지속될 수밖에 없다. '친일시'를 문학적 담론의 층위에서 해명하고 해소하기 위해서는 그것이 지닌 미학적인 내적 논리를 밝혀야 한다. 이 논리는 독자의 현실 세계에 대해 전체론적 상상 세계를 강요하는 논리이며, 제국주의적이거나 전체주의적인 맥락에 쉽게 결부되고, 탈맥락적인 상황에서는 '순수시'나 심지어 '민족시'로 까지 읽히게 될 가능성이 있는 논리이다. 따라서 '친일시'는 역사적으로 특정 시기 동안 표면화된 현상이기는 하였으나, 그 이름을 벗어버리더라도 그것의 심미적, 윤리적 작용과 효과는 지속되는 담론효과를 지니고 있는 것이다. 문학교육에서 이러한 담론효과는 특별히 문제적이다. 문학교육은 '친일시'나 '친일시 담론'를 교육과정에서 배제하는 대신 이를 텍스트로 삼음으로써 지금까지 지속되어 온 '친일시'의 교육적, 문학적 영향들을 바로잡을 필요가 있다. In this study I investigated the reason why 'Pro-japanese Poetry' has become a problematic phenomenon up to now. As a result of study, I detected the fact that the majority of the critical discourses of the 'Pro-japanese Poetry' didn't function as literary discourse after the independence. Dealing with 'Pro-japanese Poetry' of the historical and spiritual dimension has inappropriate influence on reader's emotional imagination system. To clear up the problem of 'Pro-japanese Poetry', we must disclose its internal esthetic logic. This logic forces the reader to accept the totalitarian imagination world, joins with imperialistic context easily, and has possibility of 'Pro-japanese Poetry' being read as a 'Pure Poetry' or a 'National Poetry'. 'Pro-japanese Poetry' is the phenomenon of historically specific period, but its esthetical and ethical working has quite a long discourse effect. Literary education must not exclude 'Pro-japanese Poetry' or 'discourse of pro-japanese poetry' from the literary curriculum, but include it as texts.

Dibucaine-selective poly(vinyl chloride) menbrance electrodes were designed based on ion-association complex between dibucaine and metal iodide complex such as H??, Bil?? and CdI??. Stable potentiometric response was obtained with Meyer reagent at pH 3.0-5.5, with Dragendorff reagent at pH 3.0-5.0 and with Marume reagent at pH 3.0-5.5. The best plasticizer was 49 w/w% acetyl-tri-n-butly critrate for Meyer reagent, 65.3 w.w% for Marume reagent. The electrodes exhibited a linear response based on Meyer, Dragendorff and Marume complex were the concentration range of 2×10?4×10?M ,2×10×4×10?M, 2×10?1×10?M,respectively. The potentiometric response slope of optimized membrane electrodes based on Meyer, Dragendorff and Marume complex for dibucaine were 56.12,57.81 and 56.45?? with relative standard deviation of 2.75, 2.29 and 1.96%, respectively. This ISE methods are found to be sensitive, rapid, fairly accurate and are able to be empolyed successfully for the determination of dibucaine preparations.
