Purpose: The purpose of this study was to identify the effect of a mentoring program as a strategy for the retention of clinical nurses. Method: Research subjects were 20 mentors, 20 mentees and 22 clinical nurses for a control group of mentees. A mentoring program was developed by an expert committee and applied to the experimental group for six months. Data were collected at three and six months after the application of the program from September, 2008 to March, 2009. Data were analyzed using $x^$-test, t-test, Repeated Measures ANOVA, One-way ANOVA in SPSS/Win 15.0 Program. Results: Job satisfaction, organizational commitment, empowerment, and carrier commitment in the mentees of the experimental group were significantly higher than the nurses of the control group. Intention of resignation in mentees of the experimental group were significantly lower than the nurses of the control group. Also, there were significant interaction between the groups and the times of measurements in all variables. Conclusion: The mentoring program showed positive impact on the variables for maintenance of clinical nurses. Recommendation: Based on these findings, retention strategies using mentoring programs were recommended to reduce clinical nurses' resignation and improve the competency of clinical nurses that leads to the productivity of nursing organizations.

Purpose: The purpose of this study was to identify the effect of anterolateral (45$^{\circ}$) and lateral (90$^{\circ}$) direction resistance, with using an elastic band, on the electromyographic(EMG) activity ratio of the vastus medialis oblique (VMO) and the vastus lateralis (VL) during squat exercise. Methods: The study subjects were 19 active people with no history of patellofemoral pain, limitation of range of motion or pain when performing squat exercise. A 'repeated measures within subjects' design was used. The subjects were asked to perform three repetitions of a 90$^{\circ}$ knee flexion squat exercise with anterolateral (45$^{\circ}$) and lateral (90$^{\circ}$) resistance and without resistance, respectively. The EMG activity of the VMO and VL were recorded by surface EMG electrodes and the results were normalized by the % MVIC value. Results: Repeated measures ANOVA's revealed that squat exercise with anterolateral (45$^{\circ}$) resistance produced significantly greater VMO/VL EMG activity ratio than that with lateral (90$^{\circ}$) resistance and without resistance (p=.013). Yet the result of contrast testing revealed that squat exercise with lateral (90$^{\circ}$) resistance showed no significant difference of the VMO/VL EMG activity ratio, as compared with squat exercise without resistance (p>0.05). Conclusion: The findings of this study suggest that squat exercise combining anterolateral (45$^{\circ}$) resistance can contribute positively to the patients with patellofemoral pain as they increase the VMO/VL EMG activity ratio.

Purpose: This study was done to present guidelines for deciding appropriate times for measuring blood pressure (BP) in patients with neurological disorders who had surgery due to brain damage. Method: It was a repeated measures-experimental research on time variants in BP after nursing care. SBP (Systolic BP) and DBP (Diastolic) were measured every 2 minutes up to 5 times using an EKG patient monitor. Measured data were analyzed using repeated measures ANOVA and paired t-test. Results: For suctioning, there were significantly higher differences for SBP averages after 2 min. (138mmHg, p<0.01) and 4 min. (133mmHg, p<0.01) compared to before suctioning (120mmHg). For position change, there were significant differences in SBP averages after 2 min. (136mmHg, p<0.01) and 4 min. (130mmHg, p=0.01) compared to before changing position (121mmHg). For position change followed by suctioning there were significant differences in SBP averages after 2 min. (136mmHg, p<0.01), 4 min. (136mmHg, p<0.01) and 6 min. (125mmHg, p=0.003) compared to before the interventions (121mmHg). Conclusions: Results indicate that there are significant differences in SBP and DBP over time during nursing interventions, suggesting clinical measurement of BP after 6 min. or 8 min. be done for patients with neurological disorders in neurosurgery clinics.

Purpose: Ineffective communication between healthcare professionals leads to medical errors and puts patients at risk of harm. The aim of this study was to examine the effects of interdisciplinary communication training in simulated settings on self-confidence in communication, observed communication behavior, and technical skill performances of nursing students. Methods: A repeated measures design with one group was conducted. Data was collected from 92 nursing students through a self-administered questionnaire and an observed behavior checklist. Data analysis was performed using descriptive statistics, a paired t-test, the Wilcoxon signed rank test, the Friedmann test, a Repeated Measures ANOVA, and the Spearman correlation coefficient. Results: Self-confidence in communication, observed Identification-Situation-Background-Assessment-Recommendation-Read Back communication behavior, and technical skill performances of nursing students were significantly improved. In observed communication behavior, the performance of Assessment and Read Back communication significantly improved. However, communication of Background, Assessment, and Recommendation did not improve to a satisfactory level. Observed communication behavior was not correlated with the overall technical skill performance. Conclusion: These results indicate that interdisciplinary communication training in simulated settings was effective in improving nursing students' confidence and communication skills with physicians. Longitudinal studies with larger samples are recommended in order to verify the effects of interdisciplinary communication training on clinical outcomes as well as communication competence.

Objective : Having a reliable and reproducible measurement technique to measure the sagittal contour in vertebral fractures is paramount to clinical decision making. This study is designed to determine the most reliable measurement technique in osteoporotic vertebral compression fracture. Methods : Fifteen lateral radiographs of thoracic and lumbar fractures were selected and measured on two separate occasions by three spine surgeons using six different measurement techniques [Centroid, Harrison Posterior Tangent Methods and 4 different types of modified Cobb method]. The radiograph quality was assessed and the center beam location was determined. Statistical analysis including ANOVA for repeated measures was carried out using the SAS software [v 8.0]. Results : The inter and intraobserver variance of the Cobb method 4 and Harrison posterior tangent method were significantly lower than the other four methods. The intraobserver correlation coefficients were the most consistent using the Cobb method 4 [0.982]. which was followed by the Harrison posterior tangent [0.953] and Cobb methods 1 [0.874]. The intraobserver agreement [% of repeated measures within 5 degrees of the original measurement] ranged from 42% to 98% for each technique for all three observers, with the Cobb method 4 showing the best agreement [97.8%] followed by the Harrison posterior tangent method [937%]. Conclusion : The Cobb method-4 and Harrison posterior tangent methods, when applied to measuring the kyphosis, are reliable and have a similar small error range. The Cobb method 4 shows the best overall reliability. However, the centroid method and Cobb method using a fractured endplate do not produce an accurate result due to inter and intraobserver differences in determining the baseline.

A quasi-experiment, repeated measures design with non-equivalent control group was used to test the influence of cold therapy on the perineal discomfort and the healing state of the postpartum women undergoing vaginal delivery with episiotomy. Experiment was carried out from July 28, through October 2, 1996 with 40 postpartum women conveniently sampled from one university hospital located in Seoul. The 40 postpartum women undergoing vaginal delivery with episiotomy were as signed to experimental and control groups evenly(20 each). The instrument of measurement of perineal discomfort was 0-10 rating scale that was made by researcher and that of perineal healing state was Davidson's REEDA tool. The perineal discomfort and the healing state level were measured before and after each treatment. The treatment using ice glove that was given for the only experimental group was carried out at three points ; as soon as returning to the recovery room, 3 hours after returning to the recovery room and 6 hours after returning to the recovery room. The data was analysed by using t-test, chi-square test to determine the similarity between experimental and control groups. The hypotheses were tested using repeated measures ANOVA. The results of this study are summarized as follows; 1. The first hypothesis that the perineal discomfort level of the experimental group will be significantly lower than that of the control group(df(1,38), F=24.12, p=.0001) was supported. 2. The second hypothesis that the perineal healing state of the experimental group wil be better than that of the control group(df(1,38), F=0.48, p=.49) was not supported. Based on the results of this study, could therapy was turned out to have significant effect on the perineal discomfort of the postpartum women undergoing vaginal delivery with episiotomy.

Purpose: The purpose of this study was to compare the 1% chlorhexidine gluconate/61% ethanol (CHG/ethanol), 45% ethanol/18% 1-propanol (ethanol/propanol) and 7.5% povidone-iodine (PVI) scrub with brush to evaluate their antimicrobial effect. Method: Utilizing repeated measures design, 9 nurses participated in the study. Glove juice sampling procedure was used to evaluate microbial hand counts before the surgical hand antisepsis, one minute after hand wash, and after the surgery. Results: Waterless rub using CHG and ethanol combination resulted in a 3.94 log reduction at 1 min and 2.78 log reduction at 3 hrs. Ethanol/propanol resulted in a 2.42 at 1 min and 2.22 at 3 hrs. The traditional scrub using PVI with brush resulted in a 0.94 at 1 min and 0.95 at 3 hrs (p=.003) and 3 hrs (p=.026) after the surgical hand antisepsis. Repeated measures ANOVA results showed that there was a statistically significant difference among group (p=.002). Duncan post hoc test result showed that the PVI was less effective (p<.05) in sterilizing microbials on hands than CHG/ethanol or ethanol/propanol. Conclusion: Both of the two alcohol-based antiseptic rubs are acceptable alternatives to the PVI with brush for surgical hand antisepsis.
