The purpose of this study was to investigate the effects of patient controlled analgesia(PCA) convergence education on postoperative pain management in spinal surgery patients. Sixty spinal surgery patients were included. For the experimental group(n=30), PCA education using video, booklet, and a PCA model practice was provided before surgery. The data were collected using questionnaire and were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test and repeated measures ANOVA. PCA knowledge-attitude, PCA satisfaction and pain control satisfaction were higher in the experimental group than the control group(p<.001; p=.001; p<.001). Postoperative pain and frequency of additional analgesia use of the experimental group were significantly lower than those of the control group(p<.001; p=.001). This findings showed that the convergence PCA education of audiovisual aids with PCA practice training could be effective pain management intervention in patients undergoing spinal surgery. These apply to development of convergence nursing interventions in clinical practice.

Purpose: This study examined the influence of the maximal aerobic capacity on the two-year cardiac-related re-hospitalization in patients with heart failure with a reduced ejection fraction (HFrEF) in Korean society. Methods: The maximal aerobic capacity of the study population (n=95, male 63%) was evaluated using a cardiopulmonary exercise (CPX) testing system. Each patient was followed up for two years to divide the HFrEF patients into two groups according to cardiac-related re-hospitalization: re-hospitalization (RH) group (n=29, 30%) and no re-hospitalization (NRH) group (n=66, 70%). Results: The relative peak $VO_2$ (mL/kg/min, p<0.001), exercise duration (p<0.001), respiratory exchange ratio ($VCO_2/VO_2$, p=0.001), systolic blood pressure (SBP) reserve (p=0.004), heart rate (HR) reserve (p=0.007), SBP max (p=0.02), and HR max (p=0.039) were significantly lower in the RH group than the NRH group during the CPX test. On the other hand, the ventilatory efficiency (VE/VCO2 slope, p=0.02) and age (p=0.022) were significantly higher in the RH group than in the NRH group. In binary logistic regression analysis, the relative peak $VO_2$ (p=0.001, Wald Chi-square 10.137) was the strongest predictive factor on cardiac-related re-hospitalization, which was followed by $VCO_2/VO_2$ (p=0.019, Wald Chi-square 5.54). On the other hand, age (p=0.063, Wald Chi-square 3.445) did not have a significant influence on cardiac related re-hospitalization. Conclusion: The maximal aerobic capacity, especially the relative peak $VO_2$, is the strongest factor on cardiac-related re-hospitalization within two years in patients with HFrEF in Korean society.

Purpose: The purpose of this secondary data analysis study was to compare what factors influenced individual's satisfaction with emergency medical services (EMS). Methods: Data were obtained from the Korea Health Panel Survey 2013 with 20,641 participants. A total sample of emergency room (ER) users (n=1,709) aged 20 and over were selected and divided into two age groups, one for 1,046 adults and the other for 663 elderly. Participants' responses were analyzed using descriptive statistics, ${\chi}^2$ test and logistic regression. Results: Among adults and elderly who were transferred to other hospitals instead of being admitted or returned to their homes reported less satisfaction (${\chi}^2=10.18$, p=.006). Further, the adults who perceived their arrival to the ER as not delayed (${\chi}^2=3.74$, p=.049) or visited the ER for treatment for illness (${\chi}^2=5.32$, p=.021) reported more satisfaction than those who perceived their ER service being delayed or visited the ER for accident or poisoning. The elderly who visited ER by non-ambulance reported higher satisfaction than those who arrived by ambulance (${\chi}^2=14.15$, p<.001). Conclusion: In both adults and the elderly, satisfaction of EMS can be increased by avoiding transferring patients to other hospital. For adults to be satisfied with EMS, efficient and rapid EMS might be needed to avoid delay in ER arrival, especially for adults with accidents or poisoning.

This study examined the effects of nursing information provision using a booklet on the patients' anxiety and uncertainty with an endoscopic submucosal dissection before the procedure, which is a non-equivalent controlled pre-post test designed study. Twenty three patients in a control group received the existing intervention, which is the general education prior to the procedure without standardized format as well as an oral explanation, and 23 patients in the experimental group received nursing information with a booklet developed by the investigator of this study. The collected data were analyzed using a ${\chi}^2$ test and Fisher's exact t-test on SPSS 21.0. The experimental group reported significantly lower anxiety (t=3.319, p=.002) and anxiety behavioral responses (t=3.508, p=.001) than those in the control group. There were no significant differences in uncertainty between the groups (t=.745, p=.460). Nursing information using the booklet is a useful nursing intervention to reduce the anxiety of patients with endoscopic submucosal dissection before the procedure.

Purpose: The aims of this study were to construct a hypothetical structural model which explains the premenstrual syndrome (PMS) in adolescent girls and to test the fitness with collected data. Methods: The participants were 1,087 adolescent girls from 3 high schools and 5 middle schools in B city. Data were collected from July 3 to October 15, 2012 using self-reported questionnaires and were analyzed using PASW 18.0 and AMOS 16.0 programs. Results: The overall fitness indices of hypothetical model were good (${\chi}^2$ =1555, p<.001), ${\chi}^2$/df=4.40, SRMR=.04, GFI=.91, RMSEA=.05, NFI=.90, TLI=.91, CFI=.92, AIC=1717). Out of 16 paths, 12 were statistically significant. Daily hassles had the greatest impact on PMS in the adolescent girls in this model. In addition, PMS in adolescent girls was directly affected by menarche age, Body Mass Index (BMI), amount of menstruation, test anxiety, social support, menstrual attitude and femininity but not by academic stress. This model explained 27% of the variance in PMS in adolescent girls. Conclusion: The findings from this study suggest that nursing interventions to reduce PMS in adolescent girls should address their daily hassles, test anxiety, menstrual attitude and BMI. Also, social support from their parents, friends, and teachers needs to be increased.

Purpose: The purpose of this study was to examine the effects of sensory stimulation on premature infants. Method: Thirty three premature infants admitted to NICU of D University Hospital in C city were randomly assigned in two groups (Experimental group: 16, Control group:17). For the experimental group, tactile and kinesthetic stimulation developed by Dr. Field was applied 2 times a day for 10 days. Behavioral state was measured using the Anderson Behavioral State Scale (ABSS). Heart rate, respiration, and oxygen saturation were obtained for each infant before and after sensory stimulation. Hypothesis testing was done using the $\chi$$^2$- test, student t-test, and repeated measures of ANOVA. Result: Hypothesis 1: There was a significant difference in the daily body weight gain between experimental and control group (F= 40.77, p= .0001). Hypothesis 2: There was a significant difference in the frequency of 'inactive awake state' between two groups ($\chi$$^2$= 39.778, p= .001). Hypothesis 3: There were significant differences in the mean of heart rate and $O_2$saturation between two groups (t= -2.174, p= .037; t= 3.080, p= .005). However, there was no significant difference in the mean of respiration rate between two groups (t= -1.966, p= .581). Conclusion: The effectiveness of a sensory stimulation on weight gain and behavioral state in premature infants was supported. Further study is recommended to develop a sensory stimulation method as an independent nursing intervention for premature infant.
