Acquired communicated diverticula between the esophagus and respiratory system are infrequent, and they are caused by carcinoma, trauma, infection, and traction. This report reviews the feature of benign esophagobronchial fistula due to midesophageal diverticulum. Patient is twenty year old man with excellent result by surgical intervention . The surgical procedures consist of divertuculectomy and superior segmentectomy of lower lobe of right lung. Clinically and radiologically, the patient is free from substernal distress, regurgitation, esophagorespiratory fistula, and esophageal stricture after surgical treatment.

After open heart surgery, the patient must be carefully observed and adequately managed for his survival. This report reviewed 10 cases of ventricular septal defect and 12 mitral valvular diseases as hemodynamics early after open heart surgery. For postoperative 24 hours, clinical status was evaluated for left atrial pressure, central venous pressure,DP[LAP-CVP], peak systolic pressure, heart rate, urine amount, and other clinical findings. Especially, on postoperative fourth hour, cardiac output was most decreased, when the changes of monitoring were compared with two groups with or without using cardiotonics. Finally, we concluded as followings; 1.Postoperatively, variation of CVP was noted in VSD, but mitral valvular disease was more variable change of LAP. 2.DP was 1.3\ulcorner.4 cmH2O in VSD, and 6.4\ulcorner.2 cmH2O in mitral valvular disease. 3.Parameter using cardiotonic was CVP in VSD, and LAP in mitral valvular disease.

During the past six years from July 1977 to June 1983, fifteen adult patients of patent ductus arteriosus were surgically treated. The results were as follows: 1. Of the 15 patients, their age range was 17 to 34 years with a mean of 24 years, and sexual predominance was women [9. cf. 6 men]. 2. The most common symptom showed exertional dyspnea, and 10 patients were classed in NYHA class II, the rest were all class III. 3. On physical examination, all patients were auscultated continuous murmur, but concomitantly diastolic murmur was noted apical region in 2 patients. 4. On roentgenogram of chest, normal finding was 3 patients, and the other patients were revealed the evidence of pulmonary congestion. 5. The electrocardiogram was normal in 6 patients, but LVH was seen in 5, and 2 patients were LVH+ LAH. 6. Cardiac catheterization was performed in 12, and mean value of SO2[LPA-RV] was 6.3%, Q/Q 2.09, peak systolic pulmonary arterial pressure 45.3 mmHg, and Rp/Rs 0.365. 7. All operations were carried out by posterolateral thoracotomy. In 6 patients, division and suture of ductus were possible, the other patients were treated by division and ligation with heavy silk or Dacron patch. 8. Postoperative complications were hoarseness, persistent murmur, reoperation for bleeding, and atelectasis. Early and late mortality was 20% [3 patients], and cause of death was mainly aneurysmal rupture of previous operative site.

From May 1977 to April 1984, 204 cases of open heart surgery were performed under cardiopulmonary bypass. There were 99 male and 105 female patients ranging in age from 19 months to 58 years. 136 cases [66.7%] were congenital heart disease, and 68 cases [33.3%] were acquired heart disease, which were 66 valvular disease [97.1%], 1 IVC obstruction, and 1 myxoma. There were 136 congenital heart anomaly with 16 operative deaths [11.8%], consisting of 94 acyanotic cases with 7 death [7.4%] and 42 cases of cyanotic cases with 9 deaths [21.4%]. In 66 patients of acquired valvular disease, 52 valves were implanted; 47 mitral valve replacement with 4 death [8.5%] and 5 double valve replacement [MVR+AVR] with 1 death [20%]. Postoperative, warfarin sodium was medicated with checking prothrombin time. Finally, the operative mortality was 11.8% in congenital anomaly, and 11.8% in acquired heart disease, overall mortality rate was 8.5%.

유채의 수양검정을 함에 있어 우리나라의 여건하에서는 어떤 plot 크기와 모양이 실험의 정밀도를 높이며 가장 이상적인가 하는 간제를 작물시시장 목포지장의 토양균일도추정과 아울러 그 시험을 실시하여 얻어진 몇가지 결과는 1. 작물시험장 목포지장 시험국장의 도장균일성은 수량의 C.V.로서 표현된 균일도는 다분지성인 유달에서 약 13%있고 양질다수성인 용당에서 약 11%로서 수량검정을 위하여 불량한 편은 아니었다. 2. Plot의 크기 증가에 따라서 변이계수치의 현저한 감소를 볼수 있었으며 특히 120m2 plot에서 C.V.가 가장 낮았고 용당에서 그 현상이 더욱 뚜렷하였다. 그러나 Plot의 크기는 경제적인 면과 실험의 정밀도를 아울러 고려하여 그 적정한계를 설정함이 유익하겠다. 3. 동일면적에서의 Plot 모양는 정방형 Plot보다 장방형 p1ot에서 C.V.가 낮은 경향을 보였고 또한 시험구의 폭이 넓어짐에 따라 변이계수는 감소하였다. 4. 우리나라에 있어 유채의 수량 검정도는 육종초기 세대에는 휴장 3~6m의 plot에서 3회 반복으로 검정하고 후기세대에는 9~12m의 단열 plot에 반복을 준다면 실험의 오차도 상당히 감소시킬 수 있을 것으로 여겨진다. 3∼6m long plot with 3-4 replications will be practical for yield trials in the early hybrid generations. The C. V. values with 9m long plot was about 6.6% in variety Yudal and 13.9% in 12m plot. These results indicate that 9-12m plot with 3-4 replications could be employed in securate yield test in the advanced generations.

양북터널은 굴착과 동시에 라이닝콘크리트를 타설하였다. 터널굴착과 라이닝콘크리트의 동시시공을 위한 적정시공 Cycle을 결정하고, 이에 따른 양생기간과 양생온도를 설정하는 순으로 시험하였다. 라이닝콘크리트는 품질관리를 위해 보온장치를 탑재한 Sliding form과 양생대차를 운영하고, 균열을 최소화하기 위해 양생온도와 양생시간 및 탈형강도 등을 시험에 의해 결정하였다. 시험과정은 터널내부와 라이닝콘크리트 내부온도를 계절별로 측정하고, 양생온도별로 콘크리트의 강도를 측정하였다. 거푸집 탈형시 콘크리트 온도가 터널내부의 온도로 수렴하기까지는 $15{\sim}20^{\circ}C$의 차이로 측정되었고, 거푸집 탈형을 위한 콘크리트 초기강도 4MPa을 발현하는데는 양생온도에 따라 차이가 발생하지만 시공 Cycle에 적합한 양생시간은 약 20시간이고, 이 때의 양생온도는 $23^{\circ}C$ 이상이었다. 위의 시험결과대로 현장에서 라이닝콘크리트를 양생한 결과 시공 Cycle과 압축강도 및 콘크리트면의 외관 등이 만족한 결과를 나타내었다.
