A study of 118 autopsy cases associated with medical care in 1990 was present according to the medical department, the mode of treatment and the cause of death. The Pediatrics showed the highest rate (25.4%), followed by the Obstetrics & Gynecology (22.9%), and Internal medicine (20.2%). According to the mode of treatment, medical accidents during operation and anesthesia were 29 cases (24.6%) with highest rate in Obstetrics & Gynecology (13 cases), 38 cases (32.2%) were during medication and/or injection with highest rate in Internal Medicine (18 cases), and 51 cases (43.2%) were during general medical practice with highest rate in pediatrics (19 cases). The most prevalent cause of death was the disease of respiratory system (34.9%, 30 cases) and the diseases of cardiovascular and urogenital system accounted for 31.4% and 11.6% respectively. The main cause of death in Internal medicine was the disease of cardiovascular system (11/24 cases), the respiratory system in pediatrics (15/30 cases) and the disease of urogenital system in Obstetrics & Gynecology (9/27 cases. ) Asphyxial deaths were 7 cases and the death due to adverse drug reaction accounted for 10 cases.

N/A Sixty-three patients with esophageal varices were selected in whom endoscopic examination was performed at the Busan National University Hospital, September, 1982 and February, 1982 The esophageal varices were classified into three grades from the endoscopical point of point of view in accordance with Sesokos method of classification. A study was done for the relationship between the endoscopical findings of esophageal varices, clinical findings and spleen visualization by 198Au liver scanning. The results obtained were as follow: 1) Among 63 cases with esophageal varices, the grade of esophageal varices was severe in 31.7%, moduate in 39.7%, and mild in 28.6%. 2) In 44 bleeding patients with esophageal varices, there was significant correlation between the grade of esophageal varices and the frequency of upper gastrointestinal bleeding. Severe esophageal varices were associated with a high risk of bleeding. As the cause of upper gastrointestinal bleeding, ruptured esophageal varices (54. 5%) and hemorrhagic gastritis (24.0%) were more frequent. Bleeding source could not be observed in 11 4% of bleeding cases. 3) The grade of esophageal varices had neither significant relationship with abdominal venous dilatation nor with ascites. There was parallel relationship between the grade of esophageal varices and splenomegaly. The larger splenomegaly was, the higher grade of esophageal varices was present. 4) Somewhat correlation was observed between spleen visualization by 198Au liver scanning and the grade of esophageal varices but not statsically significant.

N/A Serum group I Pepsinogen (sPG I) levels were measured by radioimmunoassay in 159 patients undergoing endoscopy, then all patients were classified by endoscopic diagnosis, gastric mucosal histology, and smoking habits. The results were as follows: 1) Both nonulcer dyspepsia and duodenal ulcer smokers had significantly higher sPG I levels than their nonsmoking controls (p<0.005). 2) The frequency distvibution of superficial gastritis in the nonulcer dyspcpsia group with smoking habits revealed significantly higher levels than that of the nonsmoking controls (p<0.0025). 3) Serum PG Iin nonulcer dyspepsia patients revealed significantly higher levels in patients with superficial gastritis but there were not related to cigarette smoking. 4) The relationship between the mean level of serum PG I and fundic mucosal histology in duodenal ulcer patients was found to be statistically insignificant, but the mean level of sPG I in the smoking group showed a higher value than that of the nonsmoking controis (p< 0. 05). 5) The frequency distribution of high serum PG I level (> 80 ng/ml) in duodenal ulcer smokers was higher than that of the nonsmoking control group (chi square test: p<0.). From the above findings, it is concluded that the smoking induced increase in sPG I in duodenal ulcer is proposed to release an augmented pepsin secretory capacity, which can have aetiologic significance in association between smoking and duodenal ulcer.

<P>With a simply modified circuit design connecting a Pt/NiO/Pt capacitor to a serial load resistor (R<SUB>L</SUB>), resistive switching (RS) characteristics are significantly improved. Distributions of current at low-resistance state and switching voltages during reset and set processes are much reduced, and RS endurance is much enhanced. Using percolation theory, we find that a multiply connected conducting filament (CF) is preferentially formed in a Pt/NiO/Pt capacitor serially connected to an R<SUB>L</SUB> of 1 kΩ. The multiply connected CF may provide uniform heat distribution to a Pt/NiO/Pt capacitor, resulting in reduced randomness during heat-assisted reset process and improved RS characteristics.</P>

본 논문은 비선형 해저드 모형을 이용해 산업별 수입침투율 상승이 개별 노동자의 일자리중단 확률에 미친 영향을 실증적으로 분석한다. 주요 결과는 다음과 같다. 첫째, 수입침투율 상승은 일자리 안정성에 상당히 크고 통계적으로 유의한 부정적 영향을 미친다. 산업 총공급대비 수입 비중이 1%p 증가하면 해당 산업에서 일하는 노동자들의 이직 확률은 4.5%p 증가한다. 둘째, 무역자유화의 효과는 수입과 수출 간에 비대칭적이다. 수입침투율의 경우와 달리 수출의존도가 일자리 안정성에 미치는 영향은 통계적으로 유의하지 않다. 셋째, 수입침투율이 일자리 안정성에 미치는 부정적 효과의 크기는 노동자 특성에 따라 다르다. 중소기업과 무노조 기업에 속한 노동자와 저학력 노동자가 더 큰 부정적 영향을 받는다. This paper provides empirical evidence on the impact of increasing import penetration on the job stability of Korean workers. The main results are as follows. First, import penetration negatively affects job stability. If an industry`s ratio of imports to total supply increases by 1 percentage point, the turnover probability of workers in that industry increases by 4.5 percentage points. Second, the effect of trade liberalization is not symmetric between imports and exports. Unlike the case of imports, an industry`s ratio of exports to output does not have a significant effect on job stability. Third, the impact of import penetration is not uniform across different types of workers. The negative impact is greater for workers in small firms, less educated workers, and those not protected by labor unions.

N/A The authors evaluated the diagnostic accuracy of ultra sonography in the differential diagnosis of jaundice in 63 cases who were confirmed byoperation and other diagnostic methods from Jan. to Aug 1982 at the department of internal rnedicine in Busan National University Hospital. Of 63 cases of jaundice, on ultrasonographic examination biliary obstruction was 36, and non-obstruction of bile duct was 27 according to the degree of bile duct dilatation(common bile duct 6mm, intrahepatic bile duct>4 mm). The sensitivity of ultrasonography in the diagnosis of biliary obstruction was 92% and specificity was 92,%, therefore overall accuracy of ultrasonography in the differential diagnosis of jaundice was 92%. In the detection of the exact caseses of jaundice the diagnostic accuracy of ultrasonography was 54% in obstructive jaundice, 38% in non-obstructive jaundice. So ultrasonographic examination appears to be a simple, reproducible, and high accurable screening method in the differentical diagnesis of jaundice although relatively low valuable in the diagnosis of exact causes of jaundice.
