During the period of 3 years and 7 months from April, 1976 to October, 1979, 60 cases of surgical jaundice were treated at department of general surgery in Chungnam National University Hospital. These surgical jaundiced patients had frequently more serious symptoms and more higher mortality in compared with patients without jaundice following surgical procedures. The 60 cases of obstructive jaundiced patients were analysed to clarify the cause of high mortality and the results were summerized as follows. 1. The overall incidence was 3.4%. The most predominant incidence of 60 surgical jaundiced patients were 28 cases of common bile duct stone, 46.7%, next common disease of them were 10 cases of acute cholecystits including of G. B. empyema, 16.7%, third common disease of them were 6 cases of perforated G. B. empyema, 10%. There are 52 cases)36.7%) of benign disease and 8 cases (13.3%) of malignant disease in 60 cases of patients. 2. The predominant age group was from 31 year old to 60 year old and the age distribution showed number of these patients was 46 cases, 76.6%, and the age distribution showed 13 year old to 74 year old. 3. The ratio of male and female was 2.3 : 1. 4. The most common operative procedures were cholecystectomy with T-tube drainage and their numbers were 37 cases, 61.7%, next common groups were 11 cases(18.3%) of choledochoenterostomy. 5. The overall postoperative complications in this series was 19 cases, 31.7%. The most common complication was 10 cases of wound infection(16.7%). 6. The overall mprtality was 10%(6/60 cases). The major causes were sepsis and hepatie failure.

In order to the measure the through-plane thermal diffusivity of polymer adhesive epoxy, which is frequently and widely used in industries, we constructed a modified AC calorimeter. The thermal diffusivities obtained for epoxy bonding layers between stainless-steel plates were 0.062~0.071×10-2 cm2/s. The reasons for these values being smaller than the reference value of 0.128×10-2cm2/s are the changing of the array of molecules when the epoxy becomes a films and the contact thermal resistance from the interfaces between the stainless and the epoxy layers. 산업 전반에 많이 사용되는 고분자 접착제인 에폭시의 면에 수직한 방향의 열 확산도를 측정하기 위하여 기존의 교류열량계를 변형하여 측정장치를 제작하였다. 스테인레스 스틸 304 층들 사이에 에폭시 접착막을 만들고 접착막의 면에 수직인(두께) 방향의 열확산도를 측정해 본 결과 0.062~0.071×10-2cm2/s를 얻었다. 문헌에서 제시된 덩치시료의 열확산도 0.128×10-2cm2/s보다 작은 값을 가지는 것은 고분자 접착제가 필름의 형태일 때는 분자의 배열이 달라지며 또한 시편 경계 면에서의 구조적인 접촉 열 저항에 기인하는 것으로 판단되었다.

Neonatal surgery is a more specialized field in pediatric surgery and to a large extent the surgery of congenital malformations. Authors reviewed the neonatal surgical diseases and tried to find problems in the management of these patients at the department of general surgery, Chungnam National University Hospital from Aug. 1983 to Oct. 1984. 12 nonatal surgical disease were collected among 129 pediatric surgical patients which were 3 jejunal atresias, 2 gastroschisis, 2 ompholocele, 1 Hirschsprung's disease, 1 anorectal anomaly and 3 congenital hypertrophic pyloric stenosis. Mortality developed in 3 patients all of whom needed a long term parenteral hyperalimentatiion Two of 3 fatal cases were premature neonates.

This study is a review and analysis of 94 cases of the inguinal hernia treated at the department of general surgery, Chungnam National University Hospital from October, 1985 to September, 1987. The result were as follows: 1) Male was predominated over female by the ratio of 5 : 1. All of the inguinal hernia were indirect type. 2) The location of inguinal hernia; 41 cases(43.6%) were found in the right and left respectively and 12 cases(12. 8%) bilaterally. 3) Among 94 cases, 14 cases(14.9%) had a previous history of incarceration. Incarceration has occured only in male. The incidence of incarceration was higher in the patients whose ages are under 2 yrs(64.3%) than over 2 yrs(35.7%). 4) The incidence of combined congenital anomalies was 18. 1% and congenital anomalies were hydrocele, undescended testis, congenital heart disease, umbilical hernia and paraesophageal hiatal hernia. 5) Contralateral side operation after ipsilateral operation was performed in 4 cases(4.9%.) from 1 month to 2 yrs after initial operation. 6) The recurrence rate was 1.1%, (1/94 cases).

An analysis of 50 cases of acute appendicitis in, children under the age of 15 was carried out which were treated at the department of surgery of Chungnam National University during 3 years period from Jan. 1974 to Dec. 1976. Auther, having reviewed and analysed the clinical features, diagnosis, treatment, morbidity applied to these cases, obtained the results as followings. 1. The disease is rare under the age of 10, showed progressive increase from 10 to 15 years old. Ratio between male and female was 1.8:1. 2. Most clinical features, laboratory findings, complications and morbidity were more serious in the perforated group than non-perforated one. 3. The disease is more fulminant in the children than adult and the over-all perforation rate was 34.0% in the children, comparing with 15 to 25% of adult appendiceal perforation and the perforation rate under the age of 10 was relatively high, 57.1%. 4. There was no mortality.
