김태정,차영덕,이성근 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.35 No.1

Central venous pressure(CVP) catheter has become regarded as necessary in the care of the critically ill patients, long time operation and the anesthesia that massive bleeding is anticipated. Exact placement of CVP catheter tip is essential for prevention of complications due to malposition. The correct location of CVP catheter should always be ensured after catheterization as soon as possible. Acute cardiac tamponade is the most serious complication associated with CVP catheter tip malposition that may follow perforation of heart or pericardium. In 54-year old female patient, a catheter that was introduced through the left internal jugular vein entered left pericardiacophrenic vein. We experienced a case of cardiac tamponade caused by malposition of CVP catheter tip after 12hours of left internal jugular catheterization. (Korean J Anesthesiol 1998; 35: 163∼167)

The Melkersson-Rosenthal (M-R) syndrome consists of a triad of (1) recurrent peripheral facial nerve paralysis which develops alternately on both sides of face, (2) non-inflammatory facial edema, and (3) fissuring of tongue. A 59 years old female patient developed the left facial palsy on September, 1988. Right facial palsy developed continuously 2 months later after the spontaneous remission of left facial palsy. On February, 1989, we have found out M-R syndrome which accompanied with migraine type of intermittent headache, and hypertension in one attack of cerebral stroke several years ago, there were no diabetes mellitus, pulmonary tuberculosis and brain tumor in clinical studies. Although the causes of this syndrome were not noted, we performed the stellate ganglion block and transcutaneous electrical nerve stimulation for treatment of the palsy, but the clinical effectiveness of these were not satisfactory.

Background and Purpose Te functional recovery afer the lateral medullary infarction (LMI) is usually good. Little is known about the prognostic factors associated with poor outcome following acute LMI. Te aim of this study was to identify the factors associated with poor long-term outcome afer acute LMI, based on experiences at a single center over 11 years. Methods A consecutive series of 157 patients with acute LMI who were admitted within 7 days after symptom onset was evaluated retrospectively. Clinical symptoms were assessed within 1 day afer admission, and outcomes were evaluated over a 1-year period afer the initial event. Te lesions were classifed into three vertical types (rostral, middle, and caudal), and the patients were divided into two groups according to the outcome at 1 year: favorable [modifed Rankin Scale (mRS) score ≤1] and unfavorable (mRS score ≥2). Results Of the 157 patients, 93 (59.2%) had a favorable outcome. Older age, hypertension, dysphagia, requirement for intensive care, and pneumonia were signifcantly more prevalent in the unfavorable outcome group. The frequencies of intensive care (13%) and mortality (16.7%) were signifcantly higher in the rostral lesion (p=0.002 and p=0.002). Conditional logistic regression analysis revealed that older age and initial dysphagia were independently related to an unfavorable outcome at 1 year [odds ratio (OR)=1.04, 95% confdence interval (95% CI)=1.001–1.087, p=0.049; OR=2.46, 95% CI=1.04–5.84, p=0.041]. Conclusions Tese results suggest that older age and initial dysphagia in the acute phase are independent risk factors for poor long-term prognosis afer acute LMI.

Burkholderia sp. D5에 의한 phenanthrene과 pyrene 분해

김태정,조경숙,류희욱,Kim, Tae-Jeong,Jo, Gyeong-Suk,Ryu, Hui-Uk 한국미생물학회 2003 미생물학회지 Vol.39 No.4

Burkholderia sp. D5, a polyaromatic hydrocarbons(PAHs)-degrading bacterium, was isolated from oil-contaminated soil. The bacterium could utilize phenanthrene (Phe) as a sole carbon source but could not use pyrene (Pyr). However, the strain could degrade Pyr when a cosubstrate such as yeast extract (YE) was supplemented. The PAH degradation rate of the bacterium was enhanced by the addition of other organic materials such as YE, peptone and glucose. YE was a particularly effective additive in stimulating cell growth as well as PAH degradation. When 1 g-YE/L was supplemented into the basal salt medium (BSM) with 215 mg-Phe/L, the specific growth rate (0.28 h-1) and Phe-degrading rate (29.30 μmol/L/h) were enhanced approximately ten and two times more than those obtained in the BSM with 215 mg-Phe/L, respectively. Through kinetic analysis, the maximum specific growth rate (μmax) and PAH degrading rate (Vmax) for Phe were obtained as 0.34/h and 289 ${\mu}mol$/L/h, respectively. Also, μmax and Vmax for Pyr were 0.27 h-1 and 50 ${\mu}mol$/L/h, respectively. The degradation rates for each Phe (2.20 μmol/L/h) and Pyr (2.18 μmol/L/h) were lower in mixture substrates than in a single substrate (29.30 ${\mu}mol$/L/h and 9.58 ${\mu}mol$/L/h, respectively). Burkholderia sp. D5 can degrade Phe and Pyr contained in soil, and the PAH degradation rates in soil were 20.03 ${\mu}mol$/L/h for Phe and 1.09 ${\mu}mol$/L/h for Pyr. Polycyclic aromatic hydrocarbons(PAHs)를 분해하는 Burkholderia sp. D5를 유류 오염 토양으로 분리하였고, PAHs의 분해특성을 조사하였다. 분리균주는 유일 탄소원으로 phenanthrene(Phe)을 이용하여 생장이 가능하였고, pyrene (Pyr)을 유일 탄소원으로 이용하여 생장하지는 못하였으나 yeast extract(YE)를 공기질로 첨가해 준 조건에서는 Pyr를 분해할 수 있었다. 분리 균주의 PAH 분해속도는 YE, peptone 및 glucose의 첨가에 의해 향상되었으며, 특히 YE 첨가 효과가 가장 우수하였다. 무기염배지(BSM)에 215 mg-Phe/L와 1 g-YE/L를 첨가한 조건에서 Burkholderia sp. D5의 비생장속도(0.28/h)와 Phe 분해속도(29.30 ${\mu}mol$/L/h)는 YE를 첨가하지 않은 조건에서 얻은 비생장속도(0.02/h)와 Phe 분해속도(12.00 ${\mu}mol$/L/h)의 각각 10배 및 2배였다. Phe를 기질로 공급한 경우 최대 비생장속도(${\mu}$_max)와 최대 Phe분해속도(V_max)는 각각 0.34 h-1 및 89 ${\mu}mol$/L/h 이었고. Pyr을 기질로 공급한 경우 ${\mu}$_max와 V_max는 각각 0.27 h-1 및 50 ${\mu}mol$/L/h이었다. Phe 혹은 Pyr 단독 기질하에서 분해속도와 비교 하였을 때(29.30 ${\mu}mol$-Phe L/h, 9.58 ${\mu}mol$-Pyr L/h), 두 기질의 혼합조건에서 Phe와 Pyr 분해속도는 각각 2.20 및 2.18 ${\mu}mol$ L/ h로 저하되었다. Burkholderia sp. D5 균주는 토양에서 Phe와 Pyr을 분해할 수 있었는데, Phe와 Pyr 분해속도는 각각 20.03 및 1.09 ${\mu}mol$ L/h 이었다.

회사채 신용등급 예측에 관한 연구

김태정,문남희,문성주 한국회계정보학회 2003 회계정보연구 Vol.21 No.-

The purpose of this study is that the financial information selected by three credit rating institutions after IMF financial crisis is still valid when compared to the financial information used in previous studies. In addition, this study evaluates whether or not the prediction improves by including non-financial information in the analysis of the Discriminant model. The results of the study are as follows. First, the study found that the ratios of operation income and the dependence on short term borrowing are useful variables among the financial information selected by the three credit rating institutions. The company with a higher rate of operation inomce received a positive credit rating for its corporate bond and the company with a higher dependence on short term borrowing received a negative credit rating for its corporate bond. Second, when non-financial information was added to the financial information for Discriminant analysis, the study found that the company's governance structure(Large Scale Business Group) and its industry characteristic, as classified by the Korean Industrial Standard Classification , affected the credit rating of the corporate bonds. The accuracy of prediction using year 2000 financial and non-financial information in determining year 2001 corporate bond credit ratings was 79.3%. The accuracy of prediction using year 2001 financial and non-financial information in determining year 2002 corporate bond credit ratings was 78.9%. In contrast, when finance information was only used, the accuracy of prediction year 001 and 2002 credit ratings was 73.7% and 77.9%. Therefore, the study concluded that the credit ratings system that utilized not only financial information but also non-financial information would provide better credit rating predictability. Although non-financial information alone can not improve predictability in corporate bond rating, the study illustrates that there is a significant need for further development of non-financial information to complement financial information beyond the variables used in this study. 본 연구는 신용등급예측 모형 중에서 가장 널리 사용되는 판별모형을 이용하여 신용평가 3사가 IMF 외환위기 이후 신용평가의 예측력을 강화하기 위해 채택한 재무변수가 선행연구에서 그 유용성이 밝혀진 재무변수들보다 나은지를 살펴보고, 국내 신용평가 3사가 신용평가 예측력을 강화하기 위해 중시한 비재무변수가 판별모형에 추가적으로 감안될 경우 재무변수만을 가지고 추정한 모형보다 예측력이 향상되는지를 살펴보고자 하였다. 그 주요한 연구 결과는 다음과 같다. 첫째, 재무표만을 이용한 판별분석 결과 특정기간에 한정되지만 국내 신용평가 3사가 채택한 재무변수인 기업경상이익률, 단기차입금의존도 등은 신용등급예측에 유용한 지표가 될 수 있음을 알 수 있다. 즉, 기업경상이익률이 양호할수록 회사채 신용등급에 양(+)의 영향을 미치는 반면에 단기차입금 의존도가 높을수록 회사채 신용등급에 음(-)의 영향을 미침을 알 수 있다.

Is Conservative Treatment with Antibiotics the Correct Strategy for Management of Right Colonic Diverticulitis?: A Prospective Study

김태정,이인규,박종경,이윤석,시윤,정헌,김형진,이상철,정대영,D. Lee Gorden,오승택 대한대장항문학회 2011 Annals of Coloproctolgy Vol.27 No.4

Purpose: The goals of this study were to identify whether conservative treatment with antibiotics in right colonic divertic- ulitis (RCD) patients, our empirical method used until now, is adequate and to determine how the natural history of RCD is affected by conservative treatment. Methods: This study was designed as a case-control study. Group I was comprised of 12 patients who were managed con- servatively, and clinical data were retrospectively collected. In group II, a total of 49 patients, diagnosed by using diagnos- tic criteria for RCD and managed conservatively, were prospectively included. Results: The period of fasting was 2.7 days, and the hospital stay was 4.6 days in all patients. The intravenous and the oral an- tibiotic periods were 3.8 days and 9.8 days, respectively. There were no statistically significant differences in treatment results between the two groups except the duration of fasting and the hospitalization, and there were no complications under conser- vative treatment. Eight patients (13.1%) had recurrent diverticulitis during the follow-up period. The recurrence risk showed no significant difference between the groups. The RCD-free period after management was 60.1 months, and patients with recurrent RCD were treated by conservative treatment or laparoscopic surgery. Conclusion: Conservative treatment with antibiotics is the optimal treatment of choice for RCD and shows no increase in complications.
