Ten patients underwent operation for aortic aneurysms from Jan. 1983 to April 1988 at the Department of Thoracic and Cardiovascular Surgery, Keimyung University Hospital. There were 7 males and 3 females in this series. The age ranged from 16 to 70 years with the mean age of 45 years. The cause of the aneurysm was atherosclerosis in 8 patients, mycosis in 1 patient and unknown in 1 patient. There were two patients with ascending aortic aneurysm treated by Dacron graft replacement, with no hospital death. One patient with aortic arch aneurysm was received Dacron graft replacement under cardiopulmonary bypass and died on the 21st postoperative day because of cerebral edema. There were three patients with descending aortic aneurysm. The aneurysm in two patients was successfully repaired by Dacron graft. One additional patient with ruptured aneurysm died at operation because of ventricular fibrillation. Four patients with abdominal aortic aneurysm were underwent Dacron graft replacement and the results were good.

The records of 248 patients over 16 years of age who had undergone a surgical correction of a congenital cardiovascular malformation during the period of 10 years from August, 1978 to July, 1988 were reviewed. During this period, the incidence of congenital cardiovascular malformation in adult was 18.2% of 1376 total heart disease operated on and 25.5% of 986 congenital heart defects. Among them, there were 200 patients in acyanotic group and 48 patients in cyanotic group. Male versus female ratio was 1:1.28. The oldest patient was 59 years old female who had atrial septal defect. The mean age was 24.4 years old. The distribution of the lesions showed a large preponderance of atrial septal defects [37.19o] followed in frequency by ventricular septal defects [918.1%], patent ductus arteriosus [17.3%], tetralogy of Fallot [16.1%], and a variety of other complex malformations[3.2%]. In the pediatric age group, relative frequency was different from that of this adult group, showing ventricular septal defects, tetralogy of Fallot, patent ductus arteriosus and atrial septal defects in order of incidence. The hospital mortality and late mortality were 6.0% and 1.7% respectively. The causes of hospital death were low cardiac output in 10 patients, arrhythmia in 2, air embolism in 1, sepsis in 1 and respiratory failure in l. Clinical improvement upto NYHA functional class I or II postoperatively has been achieved and sustained in all patients following repair except the patients of late death and receiving reoperation. This result confirms that congenital heart defects in the adults can be corrected with a good outcome and an aggressive operative approach seems justified.

폐암의 외과적 치료

The records of 65 patients with a confirmed diagnosis of primary lung cancer who underwent surgical therapy at the Department of Thoracic and Cardiovascular Surgery of the Keimyung University Hospital were analyzed during the period of 8 years and 4 months, from August, 1978 to December, 1986. The peak incidence was observed in the 5th decade of life and the mean age was 52.9 years old. Male versus female ratio was 8.3:1 Cough was the most frequent presenting symptom, 76.9% then chest discomfort, hemoptysis and dyspnea followed in order. 44.6% of the patient had 2 months of prediagnostic symptomatic period, 72.3% had 5 months, and the mean was 5.7 months. As for preoperative diagnosis, 62 of total 65 patients revealed the mass lesion on simple chest x-ray, and 56 of 65 patients on bronchoscopic biopsy, 10 of 37 patients on sputum cytology and 15 of 15 patients on computerized tomography of the chest were positive. Of the 65 patients, 35 [53.9%] had squamous cell carcinoma, 18 [27.7%] adenocarcinoma, 3 [4.6%] large cell carcinoma, and 3 [4.6%] small cell carcinoma all which was oat cell carcinoma. 83.1% of the total patient was resectable, and 34 underwent pneumonectomy and 20 lobectomy. Of these 65 operations, 29 was radical resection, 25 palliative, and 11 exploratory thoracotomy. As for clinical stagings, 23 patients were in Stage, I, another 23 in Stage II and 19 in Stage III, while 16 was in stage, I, 14 in stage ll and 35 in stage III in postoperative staging evaluation. In correlation of postoperative TNM classification and radical resection, those patients who had lung cancer of stage I [14/16] and stage II [9/13] had more radical resection. As postoperative complications, one patient had massive bleeding, two empyema, one empyema with bronchopulmonary fistula, and one cardiac herniation. Operative mortality rate was 1.5% [1 patient]. Mean duration between 1st operation and discovering recurrence in 18 patients was 12.7 months.

인공판막치환술후 발생한 급성신부전에 대한 임상적 고찰

신현종 대한흉부심장혈관외과학회 1994 Journal of Chest Surgery (J Chest Surg) Vol.27 No.2

A retrospective study of 737 consecutive patients surviving the first 24 hours who underwent valve replacement surgery from July 1980 to June 1993 was undertaken to determine the prevalence, variables that could be used to predict outcome and results of therapy for postoperative acute renal failure[ARF]. Twenty-one patients[2.8 %] developed acute renal failure. Positive risk factors noted in the development of postoperative renal failure included age, New York Heart Association class III & IV, endocarditis and elevated preoperative concentration of serum creatinine. The duration of cardiopulmonary bypass, aortic cross-clamping and the total duration of the operation also closely correlated with the incidence of ARF. The mortality rate for established ARF was 38.1% and ARF was associated with a significant increase in the length of hospitalization, ventilator support and intensive care unit stay. The incidence and mortality rate of oliguric renal failure was 38.1% and 85.7%. The highest mortality rate was associated with two or more postoperative complications and serum creatinine value exceeded 5 mg/dl. We concluded that therapy should be aimed at prevention of oliguric renal failure, or at least its conversion to nonoliguric renal failure, and early institution of renal replacement therapy with intensive support probably gives the best chance for survival.

멀티미디어 및 인터넷/WWW를 이용한 무역정책론(학)의 교육과 효과

신현종 嶺南大學校附設 社會科學硏究所 1998 社會科學硏究 Vol.18 No.1

<요약문> 최근에는 전자정보통신기술이 모든 부문에 도입되어 적극적으로 활용되고 있다. 특히 이러한 기술이 교육부문에서 집중적으로 활용되고 있는 것은 매우 주목할 만한 사실이다. 교육부문에서는 멀티미디어 및 인터넷/WWW을 활용한 교육이 점차 확산되어 나가고 있다. 이러한 교육방법은 ① 교육효과의 제고, ② 교육정보의 공급 확대, ③ 학술정보의 공급 촉진, ④ 교육시장의 개방 대비, ⑤ 정보사회의 인재 양성 등을 도모하기 위해 필요하다. 이러한 교육방법의 일환으로 인터넷 홈페이지를 활용하면 교육효과가 향상될 것으로 본다. 인터넷 홈페이지는 수업계획서의 공시, 과제물의 게시, 수강생들의 홈페이지를 통한 과제물 제출, 전자우편(E-Mail)을 통한 대화, 강의내용의 게재, 강의관련논문의 탑재, 강의 관련 주요 웹 사이트(Web Site)의 접속 등이 가능하기 때문이다. 멀티미디어 및 인터넷/WWW를 활용한 수업의 효과를 설문지를 통해 조사한 결과 그 효과가 큰 것으로 드러났다. 그것은 통계표를 보면 알 수 있다. 그 긍정적 효과로서는 ① 교육정보화의 촉진, ② 수업효과의 향상, ③ 정보통신역군의 양성, ④ 가치관의 발견 등을 들 수 있다. 한편 부정적 효과로서는 ① 국어파괴현상의 초래, ② 문화적 충격 가중, ③ 자료 및 정보의 오용, ④ 인성교육의 위협 등을 예시할 수 있다. 학문분류기호 : C2106(국제경제)
