Overhead crane systems are widely used for material transportation in many industrial fields. However, undesired swing can always be found during the moving progress, especially at the end location of the transport. The swing may increase the carrying time and cause safety problems. In order to achieve the target position, this paper used a PD controller and used a fuzzy controller to reduce swing angles found during the moving progress. The performance of controller was verified through the experimental results and the simulation results by MATLAB.

McN-A-343의 家兎血壓 效果에 미치는 Anticholinesterase 및 Choline ester의 影響

辛承權 전북대학교 의과학연구소 1984 全北醫大論文集 Vol.8 No.1

1. McN-A-343 induced a hypotensive effect in urethane-anesthetized rabbits, but a hypertensive one in chlorisondamine-treated rabbits. 2. The hypotension by McN-A-343 was weakened following physostigmine injection and during methacholine infusion. 3. The hypertension by McN-A-343 was abolished or markedly weakened following injections of anticholinesterase-physostigmine, neostigmine, PX-72601-and during infusions of methacholine and urecholine. 4. It is interpreted that anticholinestrerases and choline esters antagonized the McN-A-343 by occupying the receptors which McN-A-343 would act.

The data to be presented below are based on 51 cases of placenta previa seen among the 2,726 deliveries at Department of Obstetrics and Gynecology, Jeonbug University Hospital from Jan. 1976 to Oct. 1981. The summary of results are as follows ; 1. Incidence of placenta previa was one in 53 deliveries (1.9%) and the most frequent age incidence was between 25~29 years old(45.1%). The most common parity was between 1~2 and 3~4 and each of these consisted of 15 cases(29.4%). 2. 19 cases (37.3%) were total placenta previa and remainders were 17 cases of partial placenta previa (33.3%), 10 cases of low-lying placenta (19.6%) and 4 cases of marginal placenta(7.8%). 3. There was no significant difference in the average placental weight between normal placenta with above 37 weeks of gestational age and placenta previa with same age, 685.7gm and 699.2gm respectively. 4. As compared to the ratio of the sex in the placenta previa, we could not find a specific difference. 5. Placenta previa with vaginal bleeding was above 90% and 74% of them was painless. Abnormal presentation was 25.5%. 6. The most common hemoglobin level was 10.0~11.9gm% in 19 cases (37.3%) on arrival to our hospital. The average requirement of whole blood was 2.8 pints. The largest was 3.4pints in placenta previa totalis. 7. Vaginal delivery was 4 cases(7.8%), low segment transverse Cesarean section 37 cases(72.6%), classical Cesarean section 7 cases (13.7%) and Cesarean hysterectomy 3 cases(5.9%). 8. Perinatal mortality rate was 39.2%(20cases/51 cases) and 40% of that mortality showed intrauterine fetal death. Considering that 40% of mortality showed intrauterline fetal death we recommend a rapid transport system. 9. There was no maternal death.

Social and Sexual mores have been changing rapidly and the problem of teenage pregnancy continues to grow in this country. Recently, industrialization and a complex urban society unduly prolong education and delay marriage and sexual gratification, and little attention has been given to the adolescent who are more susceptible and vulnerable than adults in physical, socioeconomical and psychological aspects. Several studies indicate that good prenatal care, meticulous medical care, intensive nutritional counselings and attention to the psychological, socioeconomic problems of pregnancy reduce the perinatal death and complication rate for pregnant teenagers. The objective of the study was to compare several obstetric characteristics and outcomes of one hundred ninety four pregnant under age 20 who were delivered at department of obstetrics and gynecology, Mokpo St. Columban Hospital from January 1992 to December 1996 to those of two hundred pregnant aged 20∼29 who were chosen at random during the same period as the control group. The results were as follows; 1. The proportion of birth to teenagers increased from 1.08% of all birth in 1992 to 2.11% in 1996. 2. Almost cases were in high teen group, age of 14∼19. The majority (58.8%) were in the age of 19. 3. 110 cases (56.7%) had no previous pregnancy history. Seven patients had three times, and one patient had four times of previous pregnancy history. 4. The frequency of prenatal care was significantly lower than the control group (p<0.05). 5. The mean gestational period was 40+1 weeks, and there was no significant difference between the study group and the control group. The incidence of preterm and postterm delivery was not significant difference between the two groups. 6. The mean weight gain of pregnant teenagers was 11.27 kg, significantly smaller than the control group. The maternal weight gain of 5.0∼9.9kg was significantly higher than the control group. 7. The mean birth weight (3.06kg) of infant was significantly smaller than the control group. The incidence of 1,500∼2,499 gm birth weight 6.2%) was significantly higher than the control group (2.0%). 8. The rate of abdominal delivery (5.7%) was significantly lower than the control group (20.5%). 9. The incidence of cephalopelvic disproportion and contracted pelvis for cesarean section was somewhat higher than the control group, but not significant statistically. 10. In the antepartum complication, anemia, cystitis, and pregnancy induced hypertension occurred more frequently in the teenage pregnancy than the control group, but not significant statistically. 11. In the postpartum complication, anemia (29.9%), urinary tract infection (13.9%) occurred more frequently than the control group, but not significant statistically. 12. The perinatal mortality, low Apgar score, intrauterine growth retardation, and congenital anomaly were not significant different between the two groups.

According to most studies, there are numerous complications of pregnancy-affecting both the mother and the fetus or neonate-among women over the age of 35. So, we have compared 542 cases of the elderly gravida over the age of 35 at the department of Obstetrics and Gynecology, Mokpo, St. Columban`s Hospital, from January 1, 1994 to December 31, 1996, with 500 cases randomly chosen young pregnant women during the same period. There results were as follows. 1. There were 542 cases of the elderly gravida among total 10706 deliveries and the incidence of the elderly gravida was 5.06%. 2. The rate of elderly gravida was increased from 4.72% in 1994 to 5.39% in 1996. 3. The maternal age distribution of elderly gravida was from 35 years to 46 years. 4. The parity of elderly gravida was that primigravida was 12.2% and multigravida was 87.8%. 5. 501 cases(92.4%) of total cases were vertex presentation and breech presentation was in 34 cases(6.3%), transverse lie in 7 cases(1.3%). 6. The preterm pregnancy was 9.2% compared with 10.4% in control group. The postterm pregnancy was 3.1% compared with 5.4% in control group. 7. The rate of cesarean section was 42.4% compared with 22.4% in control group. Among the incidence of cesarean section the highest incidence was previous cesarean section(41.3%). Other indications were elderly primigravida(28.7%), cephalopelvic disproportion(7.0%), and abnormal presentation(8.3%) in order. 8. Concerning the prenatal complication, the incidence of hypertensive disorder was 5.4% compared with 3.6% in control group. 9. The Incidence of low birth weight was 12.0% compared with 6.4% in control group. 10. The male-to-female sex ratio was 1.22: 1 compared with 1.09 : 1 in control group.

It is necessary to develop a novel technology for predicting and diagnosing anomaly conditions of the railway power system, such as voltage drop and distortion so as to prevent a fault due to a power outage of the railway power system during railroad operation. Therefore, for intelligent management and maintenance of electric power equipment for railway system, an algorithm for an anomaly condition monitoring system based on real time TEO information was developed, and field installation for performance verification of the developed module was completed. In this paper, we describe the data mining process of a real-time monitoring system for anomaly conditions of the railway power system and the process of verifying the operation of the monitoring system.
