지난 10여년간 고위험힘신의 산전감시능력에 많은 향상이 있었으며 이는 estriol 양수아자 등을 이용한 생화학적방법과 cardiotocography, ultrasound를 이용한 생물리학적방법의 개발에 의하여 달성된 것이다. 이와 더불어 cardiotocograpy와 태아혈액채취를 이용한 분만중 감시의 적극적 활용 및 신생아 관호의 향상, 제왕절개율의 상승, Factor-X (tender loving care)등의 요인에 의하여 미국등에서 현저한 주산기사망율의 감소를 실현하였다.
1. The incidence of malignant ovarian tumor among all ovarian tumor was 10.1% 2. Age distribution of malignant ovarian tumor showed the highest frequency between 40-49 years group 3. The frequency of nulliparity was 31.1% and the primary sterility rate was 18.2%. 4. Regarding menstrual history during one year prior to admission, 53.4% of all malignant ovarian tumor had regular menstrual cycle, 26.6% of them had menstrual disorder to some extent and rest of all (20.0%) had physiologic amenorrhea. 5. As to the subjective symptoms of all malignant ovarian tumor palpable mass in the lower abdomen, regardless the presence of ascites, was noticed in 71.1% lower abdominal pain in 57.8% loss of weight in 31.1% and indigestion in 17.8%. 6. Palpable masses were observed in 91.1% abdominal distension in 62.2% ascites in 42.2% anemia in 26.7% cachexia in 11.1% pleural effusion in 4.4% on objective findings. 7. Cytological examination with vaginal and cervical discharge and ascites were positive in 9.1% and 77.8% respectively. One case (5.3%) of the associated malignancy of endometrium was found by the histopathology of preopertive diagnostic curettage and surgical specimen. 8. The macroscopic and microscopic bilaterality of malignant ovarian tumor were noted in 31.1% and 44.4% respectively 9. According to the international Classficiation the clinical stage adopted by FIGO, stage I was seen in 48.9%, stage II in 2.2% stage III in 22.2% and stage IV in 26.7%.
본 논문에서는 가스보일러에 사용되는 점화트랜스를 제작하여 전류와 역률, 소비전력을 측정하였다.. 역률을 측정한 결과, 자체 제작된 점화트랜스는 외국제품에 비해 높았으며 소비전력은 낮게 측정되었다. 점화봉 간격을 2mm로 고정을 시키고 점화봉 길이가 30cm,500cm,1000cm일 때 3.45A, 14.5A, 16.2A로 측정되었다. 점화봉 간격을 4mm로 고정을 시키고 점화봉 길이가 30cm, 500cm, 1000cm일 때 , 2.8A, 10.1A, 13.2A로 측정되었다. 점화봉 간격이 6mm로 고정시키고 점화봉 길이가 30cm, 500cm, 1000cm일 때 2.73A1, 0.2A, 32.6A로 측정되었다. 점화봉 간격이 8mm로 고정시키고 점화봉 길이가 30cm, 500cm, 1000cm일 때 3.13A, 9.37A, 21.4A로 측정되었다. 점화봉 간격이 10mm로 고정을 시키고 점화봉 길이가 30cm일 때는 3.4A, 14.4A, 25.6A로 측정되었다. 결론적으로 점화봉 길이가 증가 하면 전류도 증가되었다. In this paper, the ignition trans used in the gas boiler was produced to measure current, power factor, and power consumption. As a result of measuring the power factor, the self-made ignition trans was higher than that of foreign products and the power consumption was lower. The ignition gap was fixed to 2 m, and when the ignition rod length was 30cm, 500cm, and 1000cm, it was measured as 3.45A, 14.5A, and 16.2A. When the ignition gap was fixed to 4mm and the ignition rod length was 30cm, 500cm, and 1000cm, it was measured as 2.8A, 10.1A, and 13.2A. When the ignition gap was fixed at 6mm and the ignition rod length was 30cm, 500cm, and 1000cm, it was measured as 2.73A, 10.2A, and 32.6A. When the ignition gap was fixed at 8 mm and the ignition rod length was 30 cm, 500cm, and 1000cm, it was measured as 3.13A, 9.37A, and 21.4 . The ignition gap was fixed at 10 mm, and when the ignition rod length was 30cm, it was measured as 3.4A, 14.4 A, and 25.6A. In conclusion, as the length of the ignition rod increased, the current also increased.
1. the median age was 32.8 years and median number of living children was 3.1. Two third of the acceptors were between 30 and 39 years of age and had 2 to 3 living children. 2. Regarding their education level, 57% of them had grauduated high school or college. 3. More than half of the acceptors responded that their ideal number of children was three. 4. Among the patients 6 weeks or less from LMP composing 49.7 % of all acceptors, 14.4% were proved non-pregnant macroscopically. 5. During the procedure, anesthesia was not needed in the majority of cases and Trilene inhalation was needed in 5.1% of the total. 6. Exploring curettage immediate after uterine aspiration revealed that aspiration was complete in more than 85% of the patients 7 weeks or less from LMP, however it was incomplete in 29.4% of 8 weeks group and 48.3% of 9-12 weeks group. Therefore it was suggested that the use of karman cannula in the termination of pregnancy up to 7 weeks was simple safe, effective and acceptable procedure. 7. Overall complications rate was 4.4%. This includes 0.4% of cervical injury caused by toothed tenaculum, 1.4% of vomitting 0.3% of faintness 1 case of uterine perforation caused by post-aspiration metal curettage during the procedure, Besides 1.0% of mild pelvic infection 0.9% of persistant bleeding 0.2% of retained product of conception and 2 cases of ectopic pregnancies were also included.
1. The mean maternal hCG concentrations were lower when the sex of the fetus was male than that of the female fetus 2. The mean cord hCG concentrations of male and female infants were not different as determined by the beta hCG assay. 3. There was a significant correlation between male female cord serum concentration and the respective maternal concentrations of hCG 4. There was a significant correlation between maternal and cord hCG concentration and respective placenatal weight and baby weight when the sex of the fetus was male but little significance when the sex of the fetus was female
