Background and aims : The clinical syndrome unstable angina pectoris that encompasses a variety of symptoms and clincal presentations of transient episode of myocardial ischemia, was devided to several subgroups. Also, it has variable pathophysiologic factors to cause myocardial ischemia. According to clincal presentation, coronary angiographic finding and prognostic factor, the result of unstable angina pectoris is variable. In fact, there were a few data reported on the prognosis of wide spectrum of patients with unstable angina. However, the precise risk of subgroups according to classitication has not been established because it was difficult to compare between studies. We classified unstable angina pectoris by clinical nature of chest pain, and performed to establish and compare the clinical presentations, coronary angiographic findings, treatement and prognosis of patients with unstable angina within subgroups of classification. Methods : Retrospenctive data for 164 unstable angina pectoris patients admitted to the Internal Cardiology Division of Soon Chun Hyang University Hospital from May 1996 to July 1999 was analyzed. The patients were classified into one of the following categories: Class I, new onset of severe angina; Class II, acceleration of previous chronic stable angina; Class III, angina at rest. Clinical presentations, echocardiographic findings, coronary angiographic findings, treatment and prognosis were compared. Results : From the total 164 patients, the subjects of classes were as follows : Class I, 46 cases (28.1%); Class II, 74 cases (45.1%); Class III, 44 cases (26.8%). In view of age distribution, the 7th decade had the highest incidence, and then, 6th, 8th decades were followed. There was no baseline differences among the 3 classes with respect to gender, number of risk factors. Significantly, class II showed more severe findings in abnormal Q wave 15 cases (20.8%), total occclusive lesion 10 cases (20.8%) and three vessel coronary disease 11 cases (22.9%) than other classes. The change of ST segment was significantly apparent (p<0.02) among class I 28 cases (60.8%), class III 26 cases (59.0%), comparing with class II 30 cases (40.5%). Class III had the higher incidence of one vessel coronary artery disease than class I and III. The heparin treatment was performed in 99 cases (60.1%). The incidence of nonfatal myocardial infarction was much more in class I and III, each 4 cases (8.7%, 9.8%) than in class II 1 cases (1.4%). In-Hospital death was occurred in class I and II, each 1 case. Conclusion : The patients with the acclerated angina from chronic stable angina had more severe coronary artery disease than other classes, but they had better in-hospital prognosis.

This research was performed to investigate the generation and physico-chemical characteristics of municipal solid wastes. The results were as follows: i) The generation rate and bulk density were 0.157 kg/cap/d and 147.8 g/L in residential zone, respectively. In non-residential zone, the generation and bulk density were 1.71 kg/cap/d and 85.6 g/L, respectively. Consequently, bulk density of non-residential zone was lower than that of residential zone. ii) The wastes consisted of 90% of combustibles and 10% of incombustibles in residential zone. And the wastes from non-residential zone was composed 85% of combustibles and 15% of incombustibles. iii) Water content was estimated at 47∼50% in residential zone and restaurants. In non-residential zone, except restaurants, water content was in the range of 10∼30%. Ash content was nearly 10% in overall zone.

This study was performed to estimate effluent concentration and kinetic parameters in biological nutrient removal(BNR) process using SWPP media. These systems were operated with HRT of 5hrs through 14hrs at internal recycle of 50%. The removal efficiencies of BOD, at four HRT of 5,8,10, 14 hrs, were 82.4, 89.9, 929,9 and 94.8%, respectively. The overall nitrogen removal efficiencies were 39.1%∼82.8% for T-N and 44.8%∼95.4% for NH_(4)^(+)-N. And it was found that high removal efficiency of nitrogen was obtained by long HRT. Phosphorous removal efficiencies were very low during overall operation. Therefore, further study is needed to enhance the phosphorous removal efficiency in this process. The Stover-Kincannon model was adapted to the aerobic tank. The kinetic equations, removal of NH_(4)^(+)-N and COD, were similar to monod equation. The specific maximalNH_(4)^(+)-N removal effiency(M) and proportionality constant(k) were 4.95g NH_(4)^(+)-N/㎡/day, respectively. And for the organic matters, M and K were 17.0 g COD/㎡/day and 18.0g COD/㎡/day and it was found that the experimental and the estimated values corresponded well. In the organic loading rate increased, the removal rate decreased. Thus, it was found that the adaption of the stover-Kincannon model was inadequate, because experimental and estimated value did not correspond.

Background and Objectives : Proliferating cell nuclear antigen (PCNA) correlated with the rates of cellular proliferation and DNA synthesis. It is 36-kD nuclear acidic protein, and present throughout the cell cycle. Apoptosis also correlates with tumor development. The purpose of this study is the investigate of the relationshipal PCNA and apoptotic rates in gliomas. Materials and Methods : This study analyzed 50 paraffin-embedded glioma, including 15 cases of low grade, 20 cases of high grade, and 15 cases of maligant glioma (glioblastoma multiforme), for the status of proliferating index and apoptotic rates. The evaluation of immunostaining result was based on the percentage of positive neoplastic cells. Results : Average positive cell rates of PCNA were 14.3%, 45.2% and 62.0% in low grade glioma, high grade glioma and glioblastoma multiforme, respectively. Apoptotic rates were 52.3%, 41.0% and 25.2% in low grade glioma, high grade glioma and glioblastoma multiforme, respectively. Conclusion : This results suggest that PCNA positivity was correlated with histologic grade of glial tumors. And high grade glioma and glioblastoma multiforme showed higher positive cell rate rather than low grade glioma. Apoptotic rates were higher in low grade glioma than high grade or malignant glioma. So, the PCNA and the apoptosis rates is great useful parameter for a patient’ s prognosis.

Acute unilateral airway obstruction may be developed immediately after general anesthetic induction. Tracheal intubation is essential procedure to support lives for who is coma or undergo general anesthesia, but several complications could occur. One of these is airway obstruction immediately after endotracheal tube insertion because of bronchial mucous plug, previous aspirated foreign body, hemoptysis ect. This acute bronchial obstruction may be manifested clinically by hypoxemia, cardiovascular instability, brain damage, if more aggravated to death due to partial or complete interruption of ventilation to an lung. Therefore if endotracheal tube obstruction may occur, early detection and treatment is very critical. A 53-year-old male patient underwent acute unilateral obstruction of bronchus immediately after inserted endotracheal tube, so he revealed hypoxemia, hypotension, but smooth operation and anesthetic care was progressed overall owing to endotracheal tube suction and replacement of tube.

본 연구에서는 도심지 하수관거의 특성을 파악하기 위하여 원주시를 대상으로 수질 및 유량 조사를 통하여 기존 하수관거의 침입수/유입수(I/I) 분석 및 하수관거 정비사업시 우선순위 결정을 위한 자료제공과 강우시 CSOs의 발생특성을 분석, 결과를 고찰하였다. 그 결과 원주시의 조사지점별 평균 BOD는 원주하수종말 처리장 설계기준과 비교하여볼 때 26.O~60.7%로 매우 낮게 배출되는 것으로 조사되었으며, 평가기법에 의한 원주시 도심지역의 I/I율은 평균하수량의 35.7~74.6%로 매우 높은 것으로 조사되었다. 또한, 강우시 발생하는 CSOs는 배수유역의 크기와 강우량, 강우강도, 차집용량에 따라 큰 유량차이를 보였으며, CSOs의 수질분석결과 강우초반부 초기세척(First-flush)현상으로 수질이 급격히 상승하였다가 감소하는 것으로 나타났으며, CSOs의 BOD부하를 살펴보면 일평균 BOD부하의 18.7~38.5%이상으로 인근수역으로 미처리되어 배출되는 것으로 조사되었다. 이와같이 하수관거의 I/I율과 CSOs의 발생특성은 조사지점의 특성에 따라 큰 차이가 있으므로 관거정비사업시 이에 대한 충분한 조사 및 분석이 이루어져야 할 것이다. Infiltration/Inflow(I/I) is the major deterrent to the successful performance of the sewer and the treatment systems. An excessive I/I in a sanitary sewer system can hydraulically overload the sewer lines and the wastewater treatment plants and combined sewer overflows(CSOs) are untreated wastewater during storm events. The characteristics of the CSOs are extremely variable, depending upon local physical conditions such as topography, soil conditions, degree of development and imperviousness of surface. As a result of the flow rate and water quality monitoring, biochemical oxygen demand(BOD) concentration was significantly low as 26.0-60.7% of 173mg/L which is a design standard of wastewater treatment plant. I/I rate of sewer in the center of Wonju city evaluated by assessment method was very high as 35.7-74.6% of total flow. Furthermore, 18.7-385% of BOD load of CSOs during wet weather was discharged into watershed with being untreated. As stated above, I/I running into sewer system should be considered before everything when sewer system is improved and CSOs generated during wet weather should be necessarily deliberated for design of water treatment plant and improvement of sewer system.
