The purpose of this study was to examine early emotionality and mothering and fathering antecedents of inhibition of children at age 3 years in a sample of 100 children(51 boys; 49 girls). In order to assess child's behavioral inhibition and mothering, the behaviors of each child-mother dyad was videotaped in a structured lab situation. Data on Fathering behavior were gathered through questionnaires. 2X2ANOVA, Hierachical Regression Analyses and Fisher's Z test were conducted for the statistical analyses. The main results were as follows; 1) Only small portion of the variance in subsequent inhibition could be explained by early emotionality(i.e.negative, positive, and the interaction of both emotionality). 2) High negativity coupled with low positivity in infancy predicted high inhibition especially for girls. 3) In general, sensitive mothering and appropriateness of mothers' response were related to child's low inhibition, while parental intrusiveness and negative affect increased child's inhibition. 4) Mothering appeared more influential in the case of children who showed low positivity during infancy. The importance of distinguishing positive and negative emotionality in infancy and studying parental behavior to predict child's inhibition were discussed.

The prediction of AOV(air-operated valve) performance is normally evaluated by the allowable opening thrust margin for the opening and closing stroke. However, it is not easy to carry out the dynamic test measurement for all the valves in the nuclear power plant due to the safety and operating conditions. The analysis of the available and required thrust for the valve is simulated as an alternate method to turn around this obstacle. The required air pressures to the stem displacement are discussed for differential valve pressure obtained by experiment. The result of the simulation is compared with that of the experiment. SIMULINK in MATLAB was used for the simulation and the results show good agreement with the actual test carried out with Fisher globe valve.

Purpose: The purpose of this study was to investigate sleep patterns and predictors of excessive daytime sleepiness (EDS) in university students. Methods: Participants were 120 university students who were attending two universities in S-city and C-city. Data were collected from May 20 to June 15, 2012 using self-report questionnaires which included Johns' Epworth Sleepiness Scale, Yi's Sleep Quality Scale, and Beck Depression Inventory. Data were digitalized and analyzed using frequency, percentages, means and standard deviations, Wilcoxon rank sum test, Chi-square test, Fisher's exact test, and multiple logistic regression with SAS 9.0. Results: Mean total sleep time was 6.6 hours on weekdays, 8.1 hours on weekends. Mean sleep latency was 19.1 minutes and the score for mean sleep quality was 22.6. Prevalence of EDS was 12.5%. Depression was significantly different between EDS and Non-EDS students (t=2.17, p=.030). Multiple logistic regression showed that the only factor associated with EDS was depression (adjusted odds ratio of depression=5.33, 95% Confidence Interval=1.49-19.04). Conclusion: Results of this study indicate that university students experience short sleep time, low sleep quality, and common EDS with depression, suggesting that students with complaints of EDS should be completely assessed for depression as well as sleep problems.

Purpose: The study was done to investigate whether positioning relieves the back pain and enhances comfort during bed rest after transhepatic arterial chemoembolization(TACE). Methods: A quasi-experimental design with non-equivalent control group non-synchronized design was used. The experimental group was placed semi Fowler's position for the first 2 hours. The following 4 hours the position was rotated hourly between 30 degrees laterally inclined position and a semi Fowler's position. The control group was maintained in a supine position for the 6 hours. Data were analyzed using t-test, $x^2$-test, Fisher's exact test and repeated measures ANOVA. Results: 1) Back pain intensity significantly decreased in the experimental group compared to the control group. 2) Comfort level significantly decreased in both groups, but there was no significant difference between the two groups. 3) There were no hematoma and bleeding complication in either group. In addition, there was no significant difference in urinary retention between the two groups. 4) Analgesics were less frequently taken by the experimental group. Conclusion: These results suggest that positioning relieves back pain without causing an increased incidence of hematoma and bleeding formation after TACE and this nursing intervention might help patients be more comfortable during the treatment of TACE.

Purpose: This study was conducted to test the effects of a spiritual care empowerment (SCE) program on the psychological empowerment for nursing students. Methods: A nonequivalent control group pretest-posttest design was used. The participants were 80 nursing students (41 in the experimental and 39 in the control group) recruited from the D and S universities. The SCE program used in this study was developed based on the Zimmerman's Psychological Empowerment Model. The experimental group attended 9 sessions of a SCE program. Sessions were 90 minutes each, held twice per week for 5 weeks. Data were analyzed using Chi-square, Fisher's exact test, and t-test using SPSS/WIN 18.0. Results: Intrapersonal (self esteem and existential well-being), interactional (empathy), and behavioral (spiritual care competence) components were significantly improved in the experimental group after the intervention compared to the control group. Conclusion: The results show that the SCE program could be effective in improving the psychological empowerment of nursing students. Accordingly, the SCE program would be applied to the nursing curriculum that enhances students' psychological empowerment.

Purpose: The purpose of this study was to compare the differences in fatigue, sleep quality and interpersonal relationship stress levels between nurses in comprehensive nursing care wards and in general wards. Methods: Data were collected using self-reported structured questionnaire from 14 August to 17 September 2018. The participants were 220 nurses from 6 hospitals in Seoul and Gyeonggi-do. The data were analyzed using the IBM SPSS 23.0 program, descriptive statistics, t-test, ${\chi}^2-test$, Fisher's exact test, and Pearson's correlation coefficient. Results: The subjects' fatigue, sleep quality, and interpersonal relationship stress were not significantly different between the comprehensive nursing care services wards and the general wards. The interpersonal stress with a superior was statistically higher among general wards than comprehensive nursing care services wards. The relationship stress between patient and caregiver was higher in comprehensive nursing care services wards than in general wards. Conclusion: A follow-up study is needed to develop a strategic method to reduce interpersonal stress in nurses.

Purpose: The purpose of this study was to examine the effects of self-care intervention using a mobile instant messenger on hemodialysis patient's knowledge, self-efficacy, self-care behavior and physiological indices. Methods: A non-equivalent control group pretest-posttest design was used. The participants consisted of 38 patients who had a regular hemodialysis of Seoul National University Hospital. They were assigned to one of two groups; an experimental group (n = 19) that had self-care intervention for 8 weeks and a control groups (n = 19) that had routine hemodialysis treatment. The data collection was conducted from September 5, 2022 to October 29, 2022. The date were analyzed by Chi-square test, Independent t-test, and Fisher's exact test using SPSS Win 29 program. Results: There was a significant difference in self-efficacy (t = 3.42, p = .002) between experimental and control groups. There was no significant differences between the two groups in knowledge (t = 0.80, p = .428), self-care behavior (t = 0.09, p = .929), potassium (t = -0.82 p = .416), phosphorus (t = -0.03, p = .974), weight gain (t = 0.16, p = .867). Conclusion: Based on above results, it was verified that self-care intervention in this study was an effective indicator in improving the self-efficacy. There is a requirement to formulate comprehensive interventions capable of enhancing various indicators.

Purpose: The purpose of this study was to identify the relationship between marital satisfaction and the quality of life for women and men who live in a rural area in Korea through an international marriage. Methods: A descriptive correlational research design was used. Ninety-one women and 56 men were surveyed from May 1st., 2007 to April 6th., 2008. Data were analyzed by t-test, Pearson's correlation coefficients, and Fisher's exact test. Two types of questionnaires were used: Marital satisfaction scale (MSS) and WHO quality of life-brief (WHOQOL-BREF). Result: There is a gap between men's age and women's in the average of their marriage ; 37 vs 24. In addition, men's marital satisfaction was much higher than women's (t =2.16, p=.032) and quality of life was also higher than women's (t=-0.85, p=.005). According to this survey, therefore, it has been shown that there is a positive correlation between marital satisfaction and the quality of life (r =.435, p<.001). Conclusion: In order to improve the quality of life, marital satisfaction should be promoted by practical family nursing programs and it is necessary for the internationally married women to be continuously provided with language education and cultural awareness.

Purpose: Women's weight perception and obesity-related quality of life were analyzed according to BMI (Body Mass Index). Methods: A survey was conducted using self-report questionnaires from 178 participants. The data analysis included descriptive statistics, frequency, percentage, t-test, ANOVA, Fisher's exact test and Kendall's tau using the SPSS version 14.0. Results: There were significant differences in BMI according to age (F=8.037, p=<.001), weight perception (F=60.71, p<.001), weight control experience (F=2.504, p=.013), weight control method (F=5.839, p=.001) and weight control success (F=-2.451, p=.016). There was a significant difference in obesity-related quality of life according to weight perception in the low weight group (F=5.587, p=.021) and in the obesity group (t=3.419, p=.003). Higher correlations were found between the women's BMI group, weight perception and obesity-related quality of life. Conclusion: A program to provide appropriate information for weight perception is needed for the low weight group. There is a need for a program about weight reduction as well as weight perception for the obesity group.

Objectives: Suspending bisphosphonates (BPs) to reduce the risk and severity of medication-related osteonecrosis of the jaw (MRONJ) remains controversial. In this study, we quantitatively evaluated the clinical significance of BP suspension before surgery in osteoporosis patients with MRONJ. Materials and Methods: We analyzed 24 osteoporosis patients with MRONJ who were treated from 2012 to 2020 at Seoul National University Dental Hospital and compared the treatment outcomes of those who suspended BPs with those who did not. The number of surgical interventions, follow-up panoramic radiographs for relative bone density measurement, and laboratory blood tests including white blood cells, erythrocyte sedimentation rate, absolute neutrophil count, hemoglobin, hematocrit, and alkaline phosphatase were analyzed. ANOVA, Student's t-test, and Mann-Whitney U tests were used to compare results. Fisher's exact test was used to discover the association between treatment outcome and BP suspension, and Pearson's correlation test was used to measure the statistical relationship between the changes in serum inflammatory markers. Results: The number of interventions was significantly higher in the non-drug suspension group due to recurrence (P<0.05). The relative bone density in patients who suspended BPs was significantly different over time (P<0.05), with the highest density at one-year follow-up. Fisher's exact test shows an association between successful treatment outcomes and BP suspension. The alkaline phosphatase and erythrocyte sedimentation rate levels decreased significantly in the BP-suspended group, and a positive correlation was found between these elevated markers. Conclusion: A significant increase in bone density throughout follow-up and a lower number of interventions were found in the BP suspension group compared to the non-drug suspension group. Also, BP suspension decreased inflammatory markers in the serum after surgery, resulting in good treatment outcomes. BP suspension is a prognostic factor for MRONJ and should be implemented before surgery.
