The purpose of this study was to test the effectiveness of self-management relaxation training through biofeedback and progressive muscle relaxation methods. The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress (SOS), the McNair's profile of Mood States (POMS), the levels of ephinephrine, norepinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were sixty six nursing students divided into four groups : two groups were the biofeedback and progressive muscle relaxation groups, the other two groups served as control groups. One was a group of sophomores with no experience at all, the other a junior group without self -management or relaxation training. This study was conducted for eight weeks of clinical practice from April, 26th 1998 to June, 20th 1998. Biofeedback training was done with software developed by J&J company (1-410 form for abdominal respiration training). Progressive muscle relaxation training was done with u audiotape recorded according to Jacobson's Theory. The data were analyzed with frequencies, means, and analysis of covariance using the SPSS program and the significance level of statistics was 5%. The results of the study are : 1) The importance of clinical practice stress reduction is shown in that the level of symptoms of stress in the experimental groups in clinical practice was higher than in the group receiving only a lecture. 2) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in reducing the symptoms of stress under the clinical practice stress conditions. 3) The effectiveness of the biofeedback training relaxation method to reduce symptoms of stress was higher than that of progressive muscle relaxation. 4) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in reducing stressful mood states. 5) The relaxation training methods of biofeedback and progressive muscle relaxation were not effective in reducing epinephrine and norepinephrine levels. 6) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in increaing the number of natural killer cells. 7) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in decreasing high systolic and diastolic values of blood pressure and high pulse rates. In summary, the relaxation methods of biofeedback and progressive muscle relaxation in reducing clinical practice stress were effective in lowering the level of symptoms of stress and the profile of stressful mood states. They were also effective in lowering high blood pressure and pulse rates. The relaxation methods were effective in increasing the number of natural killer cells as part of the immune function. However, relaxation methods were not effective in reducing the catecholamine level. The biofeedback training method for reduction of symptoms of stress was more effective than the progressive muscle relaxation method.

Clinical application of composite resin recently draw great concerns in dentistry. Especially due to advantages such as esthetics, adhesiveness, simple clinical procedures, various shapes and kinds of composite resins are widely being applied to prosthodontics, conservative dentistry, and orthodontics. But, clinical problems attributable to the polymerization shrinkage of composite resin have been proposed, and we have to regard clinical problems such as secondary caries, loss of restoration, fracture of the surrounding tooth structure, marginal discoloration, and tooth sensitivity, and many portions are remained to be overcome. Therefore, this study attempts to analyze stress distribution between resin and tooth structure which is generated during polymerization shrinkage of composite resin using three dimensional finite element method. Three dimensional finite element models with conventional box-shape cavity and erosion/abrasion type V-shape lesion cavity in upper central incisor were developed. These cavities were filled with four different types of placement techniques. (bulk filling, horizontal increment filling, oblique occlusal increment filling, oblique gingival increment filling) The stresses generated by polymerization shrinkage of composite resin were calculated. The results analyzed with three dimensional finite element method were as follows : 1. The increment filling technique showed the highest maximum normal stress in both conventional box-shape and V-shape cavities and showed a tendency to decrease after complete polymerization. 2. The bulk filling technique resulted in increased stresses during the curing process in both conventional box-shape and V-shape cavities and the highest maximum normal stress occurred after complete polymerization. 3. The bulk filling resulted in the lowest maximum normal stress in both box-shape and V-shape cavities 4. Regardless of placement method, in conventional box-shape cavity, the maximum normal stress increased in dentin floor, enamel, dentin sequence and in V-shape cavity, the maximum normal stress increased in enamel, dentin sequence.

Purpose: This study was done to identify the level of knowledge on and stress from delirium among recovery room nurses, and correlations between these factors. Methods: In this study, 125 nurses agreed to participate in the study were surveyed from October 8 to October 28, 2013. Data were analyzed using t-test, ANOVA, $Scheff{\grave{e}}$ test and Pearson correlation. Results: Average percentage of correct answers to questions about delirium was 81.9% and the mean score was 26.22 (${\pm}5.01$). The mean score for recovery room nurses' work stress from emergency delirium was 3.86 (${\pm}0.99$). Extent of knowledge on delirium significantly differed by age (F=15.017, p<.001), length of clinical experience (F=22.132, p<.001), length of recovery room experience (F=10.538, p<.001), education (F=3.312, p =.040), and marital status (t=4.107, p<.001). Stress from ED was significantly related to age (F=9.185, p<.001), clinical experience (F=7.077, p=.001), and marital status (t=-2.027, p =.045). Knowledge on delirium had a negative relationship with stress from delirium (r=-.514, p<.001). Conclusion: Results show that nurses gained knowledge of delirium from their own clinical experience indicating a need to develop educational programs to improve knowledge on delirium and plans to reduce stress from delirium for recovery room nurses.

Purpose: This descriptive study is aimed at understanding how clinical nurses' terminal care attitude and spiritual health affect their terminal care stress. Methods: Data were collected from self-reported questionnaire filled by 238 nurses at a general hospital in G Metropolitan City. Results: The study showed that nurses' attitudes toward terminal care, spiritual health, marital status, and clinical experience largely affect their terminal care stress. In particular, the higher they scored on terminal care attitudes, the lower they scored on terminal care stress. These variables accounted for 52.3% of the total variance. Conclusion: The study shows terminal care attitude is an important factor for terminal care stress perceived by clinical nurses. Therefore, it is necessary to develop an educational intervention program to improve nurses' terminal care attitudes and spiritual health, which in turn would lower their terminal care stress or help them effectively cope with it.

Objective: To determine whether particular semen characteristics in various clinical diagnoses of infertility are associated with high oxidative stress and whether any group of infertile men is more likely to have high seminal oxidative stress. Reactive oxygen species (ROS) play an important role in sperm physiological functions, but elevated levels of ROS or oxidative stress are related to male infertility. Design: Measurement of sperm concentration, motility, morphology, seminal ROS, and total antioxidant capacity (TAC) in patients seeking infertility treatment and controls. Setting: Male infertility clinic of a tertiary care center. Patient(s): One hundred sixty-seven infertile patients and 19 controls. Intervention(s): None. Main Outcome Measure(s): Semen characteristics, seminal ROS, and TAC in samples from patients with various clinical diagnoses and controls. Result(s): Fifteen patients (9.0%) were Endtz positive and 152(91.0%) Endtz negative. Sperm concentration, motility, and morphology were significantly reduced in all groups compared with the controls (P = .02), except in varicocele associated With infection group. Mean (${\pm}$SD) ROS levels in patient groups ranged from 2.2 ${\pm}$ 0.13 to 3.2 ${\pm}$ 0.35, signilicantly higher than controls (1.3 ${\pm}$ 0.3; P<.005). Patient groups had a significantly lower mean (${\pm}$SD) TAC from 1014.75 ${\pm}$ 79.22 to 1173.05 ${\pm}$ 58.07 than controls (1653 ${\pm}$ 115.28, P<.001), except ill the vaseclony reversal group (1532.02 ${\pm}$ 74.24). Sperm concentration was negatively correlated with ROS both overall and within all groups (P${\leq}$.007), with the exception of idiopathic infertility. Conclusion(s): Irrespective of the clinical diagnosis and semen characteristics, the presence of seminal oxidative stress in infertile men suggests its role in the pathophysiology of infertility. Medical or surgical treatments for infertility in these men should include strategies to reduce oxidative stress.

Purpose: The purpose of this study was to investigate the effects of emotional labor, emotional intelligence and social support on job stress in clinical nurses. Methods: Participants were 123 clinical nurses and data were collected from October to December, 2011 and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with SPSS 18.0. Results: A positive correlation was found between job stress and emotional labor. Emotional labor showed a significant negative correlation with emotional intelligence and social support, whereas a positive correlation was found between emotional intelligence and social support. The strongest predictor of job stress was emotional labor. In addition, institution satisfaction (dissatisfaction) and the reason for selecting the job (opportunities for service) accounted for 21% of variance in job stress. Conclusion: The results of this study suggest that it is important to manage emotional labor as well as to improve job satisfaction in order to reduce job stress in clinical nurses.

This study is a descriptive research study for analyzing the relevance among stress, anxiety, and ego-resilience in nursing college students before clinical practice. The survey was conducted targeting the second-year students in a K college who were anticipating their first clinical practice. The survey result showed that female students showed higher stress levels than male students (t=-5.51, p<.001) before clinical practice. Female students also showed higher anxiety levels than male students (t=-3.30, p=.001) before clinical practice. The students showed higher anxiety levels before clinical practice as they felt more strongly that they were in bad health (F=3.27, p=.041), as their personality was less outgoing (t=-3.32, p=.001), and as they had a lower satisfaction level in their major (F=7.25, p=.001). The students showed higher ego-resilience levels before clinical practice as they felt more strongly that they were in good health (F=3.74, p=.026) and as their personality was more outgoing (F=3.19, p=.002). The stress and anxiety levels before clinical practice also had a positive correlation (r=.211, p=.010) and the ego-resilience and anxiety before clinical practice had a negative correlation (r=-.313, p<.001). Based on the finding, it is necessary to develop the competence improvement program that can reduce the anxiety of nursing college students before clinical practice in order to improve their ego-resilience.

Purpose: In this study, the relationship between the interpersonal relationships, clinical stress and satisfaction of clinical practice among nursing was examined. Method: The participants were 261. Data collected from 7 September to 18 September 2015 were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Result: The mean scores for the interpersonal relationship ($3.74{\pm}0.39$), stress ($3.21{\pm}0.54$), and satisfaction ($3.44{\pm}0.45$) in clinical practice were above average. Interpersonal relationships differed significantly according to year (F=3.12, p=.046), satisfaction with nursing as a major (F=15.84, p<.001), important of interpersonal relationships (F=4.76, p=.001), and academic achievement (F=3.80, p=.011). Stress in clinical practice differed significantly according to the year (F=8.05, p<.001), application motivation (F=4.55, p=.001) and satisfaction with nursing as a major (F=2.69, p=.046). Satisfaction in clinical practice differed significantly according to satisfaction with nursing as a major (F=3.24, p=.022), important of interpersonal relationships (F=3.01, p=.019), and academic achievements (F=5.24, p=.002). Significant correlations were observed between the interpersonal relationships and satisfaction in clinical practice (r=.24, p<.001). Interpersonal relationship (${\beta}=.21$, p<.001), academic achievements (${\beta}=.12$, p=.045) were factors influencing satisfaction in clinical practice. Conclusion: The interpersonal relationships need to be improved to increase nursing students' satisfaction with clinical practice

The subjects of this study were 167 students in the 3rd and 4th grade of Nursing who had experienced clinical practice at G University located in E-gun, Chungcheongbuk-do. The data collection period was from December 1 to December 18, 2020. The collected data were analyzed using the SPSS 26.0 program, and the general characteristics of subjects, clinical practice stress and clinical practice satisfaction were analyzed by frequency, percentage, mean, and standard deviation. Differences in nursing professionalism were analyzed by t-test and one-way ANOVA. The correlation between clinical practice stress, clinical practice satisfaction, and nursing professionalism was analyzed using Pearson Correlation Coefficients, and stepwise multiple regression was used to analyze factors affecting the nursing profession. As a result of the study, major satisfaction (β=.256, p=.001) was the strongest influencing variable, and clinical practice satisfaction (β=.237, p=.004) and clinical practice stress (β=.-.143, p= .068) were identified as factors affecting nursing professionalism. The explanatory power of these total variables was 21.8% (F=.14..44, p=.000). The above research results suggest that it is necessary to develop and apply educational strategies and specific programs to improve nursing professionalism.
