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.

The synthetic breaking test method was developed to evaluate the breaking performance of ultra high-voltage circuit breaker and made up of two independent circuits; current source circuit and voltage source circuit. In application of this test method, it is necessary to extend the arc of the test breaker. So, the new re-ignition system using VTGS (Vacuum Triggered Gap-Switch) was constructed to improve the efficiency and reliability of this test. In this re-ignition system, VTGS operates in high vacuum state of $5{\time}10^{17}$torr and control system consists of the triggering device and the air M-G (Motor-Generator). This re-ignition system showed the operating characteristics, such as delay time ($t_d$) and jitter time ($t_j$ not exceeding 5us and 1us respectively, and had the operating voltage of $25\~150kVdc$ at the gap distance of 24mm.

The purposes of this study were to provide the basic data and investigate the reliability of functional reach test and identify correlation of Berg balance scale (BBS) and functional reach test (FRT). The subjects were twenty healthy young adults and forty-five over 65 years old in order to compare balance ability. These data were analyzed by independent t-test and Pearson's correlation test using SPSS WIN 10.0. The results were as follows. Intrarater reliability coefficients of FRT was .976 and interrater was .942. FRT was significantly correlated with age, height, and BBS (p<.05). There were no significant differences in FRT and BBS by sex. There was significant difference in reach distance between below 74 elderly and above in FRT. FRT is very reliable test for balance and significantly correlated with BBS. Therefore, it is suggested that FRT is a clinically useful tool to substitute for BBS measuring balance ability in the elderly.
