OBJECTIVE: To evaluate the perinatal prognosis of fetuses with a single umbilical artery. METHODS: From 1992 to 1998, nineteen cases with single umbilical artery(SUA) was observed in 8,704 deliveries at Chonnam University Hospital. RESULTS: Out of nineteen fetuses, thirteen fetuses with single umbilical artery were detected by antenatal ultrasonographic examination and six fetuses were detected after birth. The male to female ratio was 0.9: 1. Congenital malformations were observed in 8 babies(42.1%) and included leg deformity, esophageal atresia, imperforated anus, ventriculomegaly, meningocele, hydronephrosis, ventricular septal defect, joint contracture, cleft lip and palate, toe anomaly, imperforated anus, kyphosis, no urethra and testis, clubfoot, patent ductus arteriosus and rnild mitral regurgitation. Among 10 cases of karyotyping analysis three cases were diagnosed as trisomy 18. Fourteen fetuses(77.8%) showed growth restriction at delivery. Antenatal obstetric complications were hydramnios(n = 3), oligohydramnios(n =2), and severe preeclampsia(n = 3). CONCLUSION: Careful ultrasonographic evaluation for the identification of a SUA is necessary because of its frequent association with congenital anomaly, growth restriction and cytogenetic abnormality.

4.Factors Influencing Self-confidence in the Maternal Role among Early Postpartum Mothers.
Korean Journal of Women Health Nursing 2013;19(1):48-56
PURPOSE: The purpose of this study was to identify the influencing factors of mothers' confidence in their maternal role during the early postpartum period. METHODS: Participants were 178 postpartum women who delivered at three specialized obstetrics and gynecology facilities and used the postpartum care facility in city B. Data were collected from February to April, 2012 using the scales of measurements of self-confidence in maternal role performance, maternal self-esteem, mother-to-infant attachment, social support, and childcare stress. Descriptive statistics, Pearson correlation coefficients, and stepwise multiple regression were used with the SPSS/WIN 18.0 program to analyze the data. RESULTS: The scores for self-confidence in the maternal role showed significant negative correlations with the scores of childcare stress (r=-.40, p<.001). Parity and maternal attachment were significant predictors and accounted for 97.4% of the variance in self-confidence in the maternal role. CONCLUSION: To strengthen self-confidence in the maternal role of early postpartum mothers, prenatal class programs need to be complemented in order to reduce childcare stress and promote mother-to-infant attachment.

5.Factors Influencing Depression in Married Immigrant Women in Korea.
Korean Journal of Women Health Nursing 2013;19(4):254-264
PURPOSE: The purpose of this study was to identify the factors influencing depression of married immigrant women in Korea. METHODS: Participants included 127 married immigrant women who met eligibility criteria and agreed to participate in the study. Participants were evaluated for subjective assessment of married immigrant-related constructs using a self-report questionnaire, for depression, acculturation stress, and social support. The analysis was done using SPSS for Windows, version 18.0, and included stepwise regression. RESULTS: The major findings were as follows; 1) Depression significantly differed according to native country, length of residence in Korea, education, family monthly income, household and primary support. 2) There were significant relationships between marital life satisfaction (r=-.80, p<.001), acculturative stress (r=.78, p<.001), and social support (r=-.20, p = .025). 3) Marital life satisfaction, family monthly income, acculturative stress, primary support and social support were significant factors, which explained 84.6% of the variance in depression (F=138.04, p<.001). Multiple regression analysis revealed that a powerful predictor of depression for married immigrant women was marital life satisfaction. CONCLUSION: Based upon the findings, this study provides useful information that could assist in reducing depression among married immigrant women, and indicates that nursing interventions are needed.

OBJECTIVE: To investigate the response of hyperplastic endometrium to Medroxyprogesterone acetate according to the histologic types such as simple typical, complex typical and atypical hyperplasia. METHODS: A total of 79 patients with histologically proved endometrial hyperplasia were enrolled into this prospective study between March 1996 and May 1998. Patients without atypia were placed on a regimen of cyclic therapy with 10mg MPA orally, each day for 14days per month for 3 months. In the cases in which hyperplasia did not regress , MPA was increased to 20mg. Patients with atypical hyperplasia received continuous MPA therapy, 20mg orally each day for 3 month. All patients were followed up for a minimum of 3 months and a maximum of 1 year(mean 7 months). RESULTS: In patients with simple typical hyperplasia, 45 patients(80.4%) had regression, 11 patients(19.6%) had persistence and none had progression. In patients with complex typical hyperplasia, 10 patients(83.3%) had regression, 2 patients(16.7%) had persistence and none had progression. But, in patients with atypical hyperplasia 5 patients(45.4%) had regression, 4 patients(36.4%) had persistence and 2(18.2%) patients had well differentiated endometrial adenocarcinoma. There was no recurrence during the follow up. CONCLUSION: This data suggest that most women with typical hyperplasia respond to progestin therapy, but there is high failure rate of response to progestin therapy and risk of endometrial cancer in patients with atypical hyperplasia. If the young patient desires to preserve her fertility, then progestin therapy may be considered as primary treatment in patients with atypical hyperplasia. But older patients in whom fertility is not an issue, hysterectomy should be selected as treatment of choice for atypical lesion.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

8.Structural Modeling of Parenting Behavior of Mothers with Preschool Children.
Journal of Korean Academy of Child Health Nursing 2011;17(2):111-119
PURPOSE: This study was done to build and test a theoretical model that could be used to explain and predict parenting behavior of mothers with preschool children. METHODS: The participants were 298 mothers with preschool children. Data were analyzed using the SAS (Statistical Analysis System) and AMOS (Analysis of Moment Structures) programs. RESULTS: Parenting stress showed a direct effect on parenting satisfaction. Parenting efficacy showed a direct effect on parenting behavior. Parenting stress showed an indirect effect on parenting behavior. Parenting efficacy was found to mediate the relationship between parenting stress and parenting behavior. Income and mother's perfectionism had an impact on parenting behavior. CONCLUSION: The outcomes of this study indicate the necessity of designing intervention programs that emphasize increasing parenting efficacy in order to increase positive parenting behavior.

9.Effects of Leader-Member Exchange of Nurses who Return to Work after Parental Leave on Conflict between Work and Family: Focus on the Mediating Effects of Job Stress
Journal of Korean Academy of Nursing Administration 2020;26(3):294-303
Purpose:
This study was done to analyze effects of leader-member exchange as perceived by nurses who returned to work after parental leave: conflict between work and family via job stress.
Methods:
A cross-sectional study design was adopted and data were collected from 140 nurses. Collected data were analyzed using the SPSS 23.0 program (descriptive statistics, t-test, ANOVA, Pearson correlation, and regression analysis).
Results:
Mean scores were 3.44±0.64 out of 5 for leader-member exchange, 3.45±0.59 out of 5 for job stress, and 2.82±0.80 out of 5 for conflict between work and family. The leader-member exchange had negative correlations with job stress (r=-.31, p=.003) and conflict between work and family (r=-.36, p<.001). The leader-member exchange had direct impacts on conflict between work and family (β=-.26, p=.002) and indirect via job stress (β=.35, p<.001). Job stress had partial mediating effects on relations between leader-member exchange and conflict between work and family (Z=-3.00, p<.001). The leader-member exchange and job stress explained 41% of the conflict between work and family.
Conclusion
The findings from this study indicate that active human resource management policies should be established in order to increase the leader-member exchange.

BACKGROUND: The survival rate of grafted fat is difficult to predict, and repeated procedures are frequently required. In this study, the effects of the freezing period of harvested adipose tissue and the addition of human adipose tissue-derived stem cells (ASCs) on the process of fat absorption were studied. METHODS: Adipose tissue was obtained from patients who underwent a lipoaspirated fat graft. The fat tissue was cryopreserved at -20degrees C in a domestic refrigerator. A total of 40 nude mice were used. The mice in the experimental group received three different subcutaneous injections in the back: an injection of fresh fat and ASCs, an injection of fat that had been frozen for one month and ASCs, and an injection of fat that had been frozen for two months and ASCs. The control mice received fat grafts without ASCs. The mice were sacrificed at four or eight weeks after the procedure, and the grafted fat tissues were harvested. The extracted fat was evaluated using photographic analysis, volume measurements, and histological examination. RESULTS: In the control group, the fat resorption rates four weeks after transplantation in the grafts of fresh fat, fat that had been frozen for one month, and fat that had been frozen for two months were 21.14%, 22.46%, and 42.56%, respectively. In the experimental group, the corresponding resorption rates were 6.68%, 13.0%, and 33.9%, respectively. CONCLUSIONS: ASCs can increase the fat graft survival rate. The use of ASCs in fat grafting can reduce the need for repeated fat grafts and provide good long term results.
