Purpose: The purpose of this study was to identify the effects of hand and foot baths on sleep and body temperature of the elderly. Methods: The research was designed for a nonequivalent control group before and after the test design. The subjects of this study totaled 43, aged 65 and over (23 people in hand bath group and 20 people in a foot bath group), who received a written voluntary consent to participate in experimental treatment and are in the W care center, S Nursing Home, and H care center in Seoul. Data were collected with questionnaires and observations, and were analyzed on the basis of frequency, percentage, mean, standard deviation, ${\chi}^2-test$, Fisher exact test, t-test and paired t-test. Results: There are no significant differences in homogeneity test of a dependent variable between groups (hand bath, foot bath). The differences between 2 groups on the sleep quality score and systolic blood pressure, diastolic blood pressure temperature were not significant statistically except on the pulse. Conclusion: Based on the results of this study, hand bath is as efficient as foot bath.

PURPOSE: The purpose of the present study was to investigate the effects of whole body vibration exercise on balance, muscle strength and falls efficacy in the elderly. METHODS: In this blinded randomized allocation study, 27 elderly were assigned to a whole-body vibration exercise group (n=14), consisting of 25 min structured exercises for 2 days per week for 6 weeks and a control group (n=13) performing the same program without vibration. At baseline and after the 6-week intervention, balance was measured using the Korean version of the Berg balance scale (K-BBS), timed up and go (TUG) test and functional reach test (FRT). Muscle strength was determined using the 30-s chair stand test (CST). Fear of falling was assessed using the Korean version of falls efficacy scale (K-FES). Paired t-test and independent t-test were used for within and between group comparisons, respectively. RESULTS: After the intervention, the experimental group showed significantly higher changes in all the parameters (K-BBS score, TUG test, CST, K-FES score) (p<.05) compared with the control group. However, there was no significant change in all parameters in the control group (p>.05). CONCLUSION: The whole-body vibration exercise program may be helpful to improve balance, mobility, muscle performance and fear of falling in the elderly.

Purpose: The present study was to examine the effects of a communication training program on nursing students' interpersonal communication and relationships. Methods: This study was quasi-experimental research using a non-equivalent pre-post design. The subjects were 40 sophomore nursing students who were divided into an experimental group of 20 members and a control group of 20 members. The communication training program consisted of 8 sessions of small group training and each session lasted 120 minutes. A pretest, posttest and follow-up test (6 months after the program was terminated) were conducted to measure Inter-personal Communication Inventory and Relationships Scale. Data was analyzed by $X^2$-test, independent t-test, paired t-test and Friedman test with SPSS. Results: The communication training program was very effective in enhancing the nursing students' communication and interpersonal abilities. Nursing students' communication ability in the experimental group, however, decreases after 6 months while there is no change in the control group. Nursing students' interpersonal relationships in the experimental group was maintained at the follow-up test. Conclusions: This study supports that a communication training program has a positive effect on improving the nursing students' communication skill and interpersonal relationships.

Sample size determination is critical, but not easy to do. Sample size defined as the number of observations in a sample to be studied should be big enough to have a high likelihood of detecting a true difference between groups. Practical procedure for determining sample size, using $G^*$power and previous dental articles, was shown in this study. Examples involving independent t-test, paired t-test, one-way analysis of variance(ANOVA), and one-way repeated-measures(RM) ANOVA were used. The purpose of this study is to enable researchers with non-statistical backgrounds to use in practice freely available statistical software G*power to determine sample size and power.

Purpose: This study aimed to identify the effects of a task-oriented exercise program on balance in patients with acute stroke. Methods: Twenty participants with hemiparesis resulting from acute stroke volunteered to participate in this study. They were randomly assigned to either the experimental or control group, with 10 patients per group. Both groups underwent a task-oriented exercise program averaging 30 minutes daily for 4 weeks. Balance was assessed before and after the 4-week training period. Before and after the intervention, we conducted a paired t-test to compare the within-group changes and an independent t-test to compare the between-group differences. The statistical significance level was set at p=0.05 for all the variables. Results: Both groups showed significant within-group and between-group changes in balance (p<0.05) after the intervention. Conclusion: This study provides valuable information for future studies in this field. Further research using a larger sample and longer experiment spans can corroborate the results of our study.
