This study purposed to verify the effects of knee balance taping therapy on knee pain and knee range of motion in the elderly with knee pain. The Quasi-experimental design, nonequivalent control group pretest-posttest was used in this study. Data collected from December 5 to 10, 2014. The participants were older than 60 with knee pain visiting senior community centers. Non-medicated elastic tapes were applied around the knee in the experimental group(n=21) and were not applied in the control group(n=19). Knee pain and range of motion were measured 3 times (before, after 1 hour, after 24 hours). Data were analyzed using ${\chi}^2$ test, Fisher's exact test, Mann-Whitney test, t-test, Repeated measure ANOVA with the SPSS version 21.0 program. The experimental group showed significantly decreased knee pain (F=34.03, p<.001) and increase in knee range of motion (F=7.83, p=.006). The results of this study confirm that knee balance taping therapy is an effective intervention for reducing pain and improving range of motion in elderly with knee pain.

The purpose of this study was to investigate effect of low-dye taping and foot intrinsic muscle strengthening exercise on the muscle activity of the tibialis anterior, calf muscles, and long calf muscles during one-foot standing in subjects with flat feet. The subjects were 16 adults in their 20s with flat feet, and they were divided into low-dye taping (LTG; n=8) and foot intrinsic muscle strengthening exercise (FSG; n=8) groups. Each group underwent the appropriate intervention twice a week for 6 weeks. The muscle activity of the tibialis anterior, long calf muscle, and medial calf muscle was measured. Repeated two-way ANOVA was performed to compare changes in muscle activity before and after the intervention. As a result of muscle activity measurement, LTG significantly decreased between before and after the experiment in all muscles (p<.05). In FSG, only the tibialis anterior significantly decreased between before and after the experiment (p<.05). Therefore, low-dye taping and foot intrinsic muscle strengthening exercises will be helpful for efficient the lower extremity muscle activity of flat foot.

This study evaluated influence of the loading head dimension on characteristics of deformation strength ($S_D$) of asphalt mixtures. Kim test and Wheel tracking (WT) test were conducted to evaluate $S_D$ characteristics with relation to WT results for various mixtures. The $S_D$ values and coefficient of variation of $S_D$ values of r=10mm were smaller than those of r=10.5mm. It was also found that $S_D$ values obtained using r=10mm loading head showed high correlations with rut parameters of WT test. It was indicated that the aggregate size and radius (r) of round cut were statistically significant variables on $S_D$ at = 0.05 level in the analysis of variance. However, in interaction of r and aggregate size showed no significance within $10{\sim}19mm$ aggregate size at the same level. Therefore, it was concluded that the diameter (D) of 40mm and the bottom edge radius (r) of 10mm was suitable dimension of loading head for deformation strength test.

This study was designed to examine whether the self-directed learning method could improve self-directed learning readiness and the effects of academic achievement level. Self-directed learning readiness was investigated among 63 first-year Medical Terminology undergraduates in the C area. A repeat measurement variance analysis of the general linear model was conducted to evaluate the effects of improving self-directed learning readiness according to the general characteristics and level of academic achievement, while a regression analysis was performed to identify the factors affecting self-directed learning readiness. Self-directed learning readiness increased from 177.3 to 180.8 for those under 18 years of age, and 192.9 to 196.5 for those over 19 years of age (p<0.05). After the team activity, the overall self-directed learning readiness was improved, and both high- and low-achieving groups showed statistically significant improvements (p<0.05). The environment surrounding learners was confirmed to have a positive effect on improving self-directed learning when given the right degree of self-directed learning and appropriate feedback. The study results are expected to form basic foundation material for professors and class designers who want to draw self-directed learning skills from memorizing subjects.

The purpose of this study is to develop middle school English classes using Problem-Based Learning(PBL) based on flipped learning and to examine its effects. Recently, various attempts to combine flipped learning and PBL have been made; however, many studies have not been applied to middle and high school curriculums yet. The attempt of this study is expected to have theoretical and practical significance. The instructional model was derived from the review of previous studies, and the development of instructional program followed the general design procedure(analysis-design-development-implement-evaluation), and its validity was secured with the advice of related experts. To verify the effectiveness of the program, the English academic achievement test and the English key competency test were conducted before and after the program. Changes in English academic achievement were analyzed by the paired-sample t-test, and the effect of key competency and the level of achievement test performance (high vs, low) on the pre-post score change was analyzed by the mixed effects repeated measures ANOVA. As a result of the analysis, both academic achievement and key competencies increased, and the low-level students in the pre-academic achievement test showed more improvements. In conclusion, the PBL class based on flipped learning is effective in improving the English academic achievement and key competencies of middle school students, and in particular, it is shown to be an effective teaching method for students with low academic achievement.

This study was conducted by performing intensities aerobic exercise for 12 weeks, three times a week targeting 28 middle aged women. The purpose of this study was analyzing factors which affect cognitive function and changes of blood pressure, renin-aldosterone system, neurotransmitter, cognitive function and working memory after treatment. The participants were divided into three groups which are the control group(n=9, non exercise), moderate intensity aerobic exercise group(n=10, 50%V02max), high intensity aerobic exercise group(n=9, 70%V02max). The two-way ANOVA(repeated measure) and multiple regression analysis were carried out to target those three groups before and after treatment. The results were as follows like this. The moderate intensity aerobic exercise increased renin, brain derived neurotrophic factor(BDNF), cognitive function and working memory. Also, it reduced aldosterone, angiotensinII and aldosterone-renin ratio. The high intensity aerobic exercise showed increase BDNF, cognitive function and working memory and decrease systolic. As a result of a multiple regression analysis of factors affecting cognitive function after intensities aerobic exercise, the moderate intensity aerobic exercise affected diastolic blood pressure, decrease of aldosterone-renin ratio and working memory. Also, an increase of BDNF affected cognitive function, the high intensity aerobic exercise affected working memory BDNF and an increase of serotonin affected cognitive function. Therefore, It could be seen that more than moderate intensity exercise increase woman's cognitive function and working memory. Also, there were metabolic factors which affect the increase of cognitive function. To moderate intensity exercise, renin-aldosterone and working memory affected to increase of cognitive function. For high intensity exercise, BDNF and working memory affected to it.
