Purpose : This study examines the effect of vibration exercise grafting PNF patterns for 6 weeks on upper body stability and equilibrium for seniors having fifteen or over of MMSE-K. Method : A total of 10 senior citizens participated in this study. Each participant performed PNF patterned exercises using vibration sports equipment for 30 minutes, once static a week, for six weeks. We measured trunk stability and balance degree before and after the six-week exercise program. Motor Assessment Scale (MAS) was used to measure trunk stability, while Functional Reach Test (FRT) and Timed Up and Go (TUG) was used to measure balance degree. The collected data was processed using paired t-test to confirm the difference between pre-program conditions and post-program conditions. Results: The results of our study show that post-program trunk stability measurements increased when compared to pre-program data; however, this increase was not statistically significant. pre and post-measurements for satatic balance and dynamic balance were statistically unchanged. Conclusion: Due to limitations in the number of participants, the procedural design of this experiment, and the limited amount of time participants actually controlled, this study failed to produce statistically significant results. However, further study should be conducted using a systematically implemented exercise program to show support for exercising with flexi-bar as an effective program for the elderly.

Purpose: This study investigated the relationship between smartphone addiction propensities and compare muscle activity of the forearms and brain wave depend on the type of smartphone when inputting text messages. Method: We used an EMG to measure the change in muscle activity by attaching pads to the four muscles in both forearms of all 16 participants. We simultaneously conducted EEG measurements by observing the changes in alpha and beta waves recorded from electrode attached to both ears and the forehead of the participants. The participants had to input a given text using three different types of smartphones for ten minutes each. Result: The comparison of the EMG when inputting text involved a one way analysis of variance and the results showed that the iPad3 was highest for muscle activity followed by GALAXY Note2 and iPhone4. For EEG measurement, a one way analysis of variance was also used and the results showed iPhone4 was higest followed by GALAXY Note2 and finally iPad3 for EEG stress score. Conclusion: The results are thought to be used as reference data for smart phone users.

Plastic injection molding products are increasing gradually in automobile components parts. Among them, large injection melded parts such a automobile bumper fascia and instrument panel are known as not only expensive but also time consuming from design to mass production. Design and manufacture of the large injection molded parts have to repeat various processing modification of mold and tryout. It could simulate design factor simulation on several conditions at mold design process by the development of CAE technology. It has effects on reduce mold making time and cost. But, these studies attach importance to small injection mold. <br/> This paper presents CAE simulation to injection molding of the large molded parts. Optimization of molding if discusses on type and location of runner and gates. And the simulation results are compared with fill time, weld line and injection pressure in actual process and parts .

Objective: The purpose of this study was to further the empirical evidence regarding exercise as an effective alternative to surgery for treating patients with low to moderate hallux valgus. Method: A total of 20 students with low to moderate hallux valgus participated in this study for six weeks. Participants were selected according to foot-print. All participants exercised using a combination of Elastic-band and Short Foot Exercises twice a week for thirty minutes each time. Measurements were taken at week 0 and week 6 for plantar foot pressure, toe angle and balance. The data was processed using a paird t-test. Results: There were significant differences in pretest and posttest measurements for balance. However there were no significants differences in plantar foot pressure and toe angle. Conclusion: Although our study did not support the effect of exercises on plantar foot pressure and toe angle, we did show evidence that exercise was effective for balance. In order to increase the effectiveness of this exercise program, patients need to be more aware of the footwear they use in their daily lives so as to contribute to the contribute to the overall effectiveness of treating low to moderate hallux valgus and offer an alternative to surgery.
