The purpose of this study was to investigate the effects of the Otago exercise program on physical function and risk of falling in elderly who have experienced falls. Thirty-six elderly people who had experienced falls more than once were randomly classified into an experimental group and control group. Each group exercised 30 minutes three times per week for a total of 8 weeks. Measurements were made using Tetrax to assess risk of falls. In addition, to measure physical function, static balance was measured using Biorescue, dynamic balance was measured using TUG, walking ability was measured using 10 MWT, and lower extremity strength was measured using FTSST. A paired t-test was conducted to verify the difference between before and after exercise in each group, and an independent t-test was performed for comparison between the groups. Regarding the experimental and control groups, static balance ability and dynamic balance ability increased significantly after exercise, and risk of falls decreased (p<.05). Lower extremity strength and gait ability increased significantly after exercise only in the experimental group (p<.05). Based on these results, the Otago exercise program is effective in improving physical function and reducing risk of falls in elderly people who have experienced falls.

The purposes of the study were to explore differences in preference for clothing images according to wearing situations and clothing product involvement. A questionnaire was developed by the researcher and was collected by 101 men and 100 women aged between 40 and 59. Data were analyzed by factor analysis, repeated measure ANOVA, t-test adjusted by Bonferroni, paired sample t-test, and independent sample t-test. The results of the study showed that clothing images were classified into five factors including hard cold image, modern urban image, bold unique image, and heavy luxurious image. There were significant differences in preference among clothing images according to wearing situations and clothing product involvement. While modern urbane image was most preferred, hard cold image was least preferred in both formal and informal wearing situations, and for either high or low involvement clothing products. Also, there were significant differences in clothing image preference according to wearing situations and product involvement. In formal situations, stronger preference for modern urban image and heavy luxurious image showed than in informal situations, and bold unique image and heavy luxurious image were more preferred for high involvement clothing product than for low involvement clothing product. In addition, there were significant differences in preferences for clothing images between groups according to gender and age. In both formal and informal situations, men showed stronger preferences than women for hard cold image, but women for bold unique image. For either high or low involvement clothing products, men preferred hard cold image, modern urban image and heavy luxurious image more than women, but women preferred bold unique image more than men. Lastly, for high involvement clothing product, subjects aged fifties showed stronger preferences than forties for modern urban image and heavy luxurious image, but for low involvement clothing product, modern urban image was more preferred.

Background: This study examined the effects of the bridge exercise with trunk rotation on the thickness of body trunk muscles, including external oblique, internal oblique, and transverse abdominis in healthy male adults. Design: Randomized controlled trial Methods: Twenty-four men were evenly divided into a trunk rotation bridge exercise group and a basic bridge exercise group by drawing lots. The two groups performed the respective exercise for thirty minutes, three times a week for six weeks. repeated measure analysis of variance (ANOVA) was used after distinguishing between three different time points before the experiment, three weeks after the experiment, and six weeks after the experiment. The significance level was set at 0.05. In case an interaction between time and group existed, the paired t-test was used to examine the within-group difference. The independent-sample t-test was used to check the between-group difference. The significance level was set at 0.05. Results: All the men showed a significant change over time in their external oblique, internal oblique, and transverse abdominis muscles. An interaction between time and group was also found (p<0.05). Conclusion: The bridge exercise with trunk rotation causes a meaningful difference in the thickness of external oblique, internal oblique, and transverse abdominis muscles. Therefore, this study proposes the use of this exercise for lower-back stabilization in future research and clinical settings.
