The objective is to evaluate the rate and indications of cesarean delivery. All live birth>27weeks at the Dongsan Medical Center, Keimyung University from 1993 to 1997(n=24,227) were respectively analyzed of delivery route, indication of cesarean birth, gestational age, and matemal age. The most common maternal age was between 26-30 years(49.6%). The most common gestational age was over 36 weeks(91.2%). Total cesarean rate was 22.3%(5,396/24,227), and primary rate was 13.6%(3,296/24,227). The annual primary cesarean birth rate and number increased gradually. Abnormal presentation was the most common indication(24.3%, 801/3,296) at primary cesarean deliveries. The second common indication was CPD(18.87%, 622/3,296). We experienced four cases of cesarean hysterectomy due to uterine atony and placenta previa. Further evaluation will be needed about the relationship between cesarean deliveries and long term fetal outcome, and the effort for VBAC will be needed.

OBJECTIVE: The objective of the present study was to evaluate incidence, parirty, gestational age, cause, termination method, and maternal complication of fetal death in utero(IUFD) clinically. METHODS: A retrospective analysis was made of the birth register and hospital records of 384 cases of the fetal death in utero among 23,703 deliveries at Dongsan Medical Center, Keimyung University during 5 years from January 1993 to December, 1997. RESULTS: The incidence of the fetal death in utero was 1.62%. The parity of mother in the fetal death in utero was the most highest in the nulliparous group(26.0%). The most common gestational week when the fetal death in utero was detected was 25-28 weeks gestational period(29.4%). The sex ratio of male vs female fetus was 1.32:1, and the cases of the fetal death in utero weighting less than 2500 gm were 332 cases(86.3%). The mode of the delivery for the fetal death in utero showed that the induction of labor was most common 71.6%, the spontaneous delivery 27.8%, and the laparotomy was 0.2%. The causes of the fetal death in utero showed unexplained causes(34.l%), congenital anomaly(I6.9%), maternal disease(14.3%), pregnancy-induced hypertension(9.6%), abruptio placenta(8.8%), cord complication(5%), and placenta previa(4%). There were 38 cases(9.8%) of maternal complication. CONCLUSION: The cause in about one third of the IUFD could not be determined by this clinical studies, so further studies with autopsy and chromosomal study must be made on stillborn infants, placenta, cord and fetal membranes in cases where the causes is unknown for the purpose of good outcome in next pregnancy.

There are many kinds of cardiac complications of hyperthyroidism such as angina pectoris, myocardial infarction, atrial fibrillation, congestive heart failure, heart block and sudden death. While angina is not uncommonly seen in association with hyperthyroidsm, it is rare that myocardial ischemia or infarction may be caused by coronary vasospasm. A 46 year-old man, who had been diagnosed with hyperthyroidism at the first admission, presented with chest pain. The serum thyroid hormone was still elevated. Serial ECGs showed significant ST elevation suggesting transmural ischemia, but coronary angiogram did not reveal any significant lesion. ECG at discharge was normalized without evidence of myocardial infartion. We report this case as an example of severe transmural ischemia with myocardial injury caused by coronary spasm associated with hyperthyroidism.

OBJECTIVE: Among various methods developed to quantitatively explore electroencephalograms (EEG), we focused on a wavelet method that was known to yield robust results under nonstationary conditions. The aim of this study was thus to introduce the wavelet method and demonstrate its potential use in clinical sleep studies. METHOD: This study involved artificial EEG specifically designed to validate the wavelet method. The method was performed to obtain time-dependent spectral power and phase angles of the signal. Synchrony of multichannel EEG was analyzed by an order parameter of the instantaneous phase. The standard methods, such as Fourier transformation and coherence, were also performed and compared with the wavelet method. The method was further validated with clinical EEG and ERP samples available as pilot studies at academic sleep centers. RESULT: The time-frequency plot and phase synchrony level obtained by the wavelet method clearly showed dynamic changes in the EEG waveforms artificially fabricated. When applied to clinical samples, the method successfully detected changes in spectral power across the sleep onset period and identified differences between the target and background ERP. CONCLUSION: Our results suggest that the wavelet method could be an alternative and/or complementary tool to the conventional Fourier method in quantifying and identifying EEG and ERP biomarkers robustly, especially when the signals were nonstationary in a short time scale (1-100 seconds).

PURPOSE: The purpose of this study was to review the articles and theses on the patient safety culture of clinical nurses for identifying overall research trends regarding patient safety culture among hospital nurses, and to suggest strategies for improving nursing work environment related to patient safety culture. METHODS: The subjects for this study were 17 articles selected according to inclusion criteria from five databases in Korea. RESULTS: Seven articles were collected from nursing journals and ten from master's theses. The studies on the 17 articles were conducted at 66 hospitals from seven regions of Korea. The tools for patient safety culture were selected among the three tools from AHRQ and two Korean translation tools. The mean score of patient safety culture was 3.43. CONCLUSION: The findings from the article review indicate that, in order to improve nursing work environment for patient safety culture, the hospital and nursing manager should emphasize the education for patient safety, communication and open-minded reporting, and cooperation among the departments of hospital.
