  • Purpose : This study aimed to investigate the effect of blood flow restriction exercise on ankle muscle strength and balance ability to achieve maximum efficiency with the same exercise intensity and time. Methods : Twenty-six adults are randomly assigned to experimental group (n=13) and comparison group (n=13). The experimental group performed ankle joint strength exercises with blood flow restriction applied while the comparison group performed ankle joint strength exercises without blood flow restriction applied three times a week for four weeks. The digital muscle measurement, Y-balance test, and Cumberland ankle instability tool were used to evaluate the subject's muscle strength, dynamic balance, and ankle instability index before and after the intervention. Results : In within-group comparison muscle strength, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was significant difference in the change of dorsiflexion, eversion strength pre and post intervention (p<.05). but plantarflexion was no significant difference between pre and post intervention in the group comparison (p>.05). In within-group comparison dynamic balance, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was no significant difference in the change of Y-balance score pre and post intervention (p>.05). In within-group comparison ankle instability index, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was no significant difference in the change of CAIT score pre and post intervention (p>.05). Conclusion : The results of this study show that ankle joint strength exercise improved the strength and balance ability of those complaining of chronic ankle instability, and ankle joint strength exercise applied with blood flow restriction was more effective in dorsiflexion and eversion strength exercise than ankle joint strength exercise without blood flow restriction.

  • This study examines the effect of sociocultural attitude toward appearance and appearance comparison on appearance management behavior by adolescents. The study examines the differences of the effect relationships among the three variables according to adolescents' sex and school grade. The questionnaire was administrated to 575 middle school and high school students in Gwangju from September 2-8, 2011. Data were analyzed by descriptive statistical analysis, frequency analysis, factor analysis, reliability analysis, and regression analysis by SPSS for WIN program. The results were as follows. First, the sociocultural attitude toward appearance was composed of two factors: internalization and awareness. Adolescent's appearance management behavior was composed of four factors: hair and style, face, weight, and neatness. There are significant differences on sociocultural attitude toward appearance and appearance management behavior by gender, age (girl/middle, boy/middle, girl/high, boy/high). Second, the sociocultural attitude toward appearance significantly influenced appearance management behavior with significant differences among groups. Third, the sociocultural attitude toward appearance significantly influenced the appearance comparison and there are significant differences among groups. Fourth, appearance comparison significantly influenced appearance management behavior with significant differences among groups. Fifth, the sociocultural attitude toward appearance mediated by appearance comparison statistically did not influence appearance management behavior.

  • Purpose: This study investigates the psychological mechanisms of comparison within the design context of retail stores, products, and advertising. The research aims to expand the understanding of comparison psychology, encompassing social, cognitive, perceptual, and self-comparisons and their application in design practices. Research Design, Data, and Methodology: The study employs a comprehensive review of psychological theories related to comparison psychology. They were selected through extensive research on literature pertaining to design psychology and consumer behavior. The research integrates insights from psychology, marketing, consumer behavior, and design theory, supported by various design examples of retail stores, products, and advertising, to demonstrate the practical applications. Results: The findings reveal that comparison psychology significantly impacts consumer preferences and user experiences. For instance, the assimilation effect and prospect theory highlight how comparisons shape value judgments and design perceptions. Practical examples are used to illustrate the profound influence of comparative judgments in design. Conclusion: The study advocates for a "psychologically-informed approach" to design, promoting designs that are not only aesthetically pleasing and functionally sound but also psychologically aligned. By bridging the gap between psychological theories and practical design implementations, the research provides valuable insights for designers, marketers, and psychologists, enhancing the psychological efficacy of design.

  • This study was to investigate the effects of SUNGSIMJIHWANGTANG(SSJHT) on the blood and brain tissues of aged rats. For the experiment, the aged rats were divided into three groups : Non treated group(NC), distilled water fed group(PC), SSJHT fed group(SSJHT). Each group was fed for ten days before administration of scopolamine. Then, we injected scopolamine intraperitoneally to PC and SSJHT group for 5 days. We observed the changes of their blood cell(WBC, RBC, platelet), blood serum(BUN, creatinine, glucose, uric acid), erythrocyte hemolysis, and the activities of cholinesterase and measured the amounts of malondialdehyde in the serum, catalase, and SOD in the brain tissue. The main results of this investigation are as follows. 1. In respect of the number of WBC, SSJHT group exhibited significant increase in comparison with PC. 2. In respect of the amount of creatinine and uric acid in the blood serum, SSJHT group exhibited significant decrease in comparison with PC. 3. In respect of erythrocyte hemolysis, SSJHT group exhibited significant suppression in comparison with PC. 4. In respect of the activity of cholinesterase in the serum, SSJHT group exhibited significant activation in comparison with PC. 5. In respect of the amounts of malondialdehyde in the serum, SSJHT group exhibited significant decrease in comparison with PC. 6. In respect of the activity of catalase in brain tissue, SSJHT group didn't exhibit significant change in comparison with PC. 7. In respect of the activity of SOD in brain tissue, SSJHT group exhibited significant activation in comparison with PC. As a result of this study, SSJHT is expected to have antiaging effect by suppressing the formation of free radicals, the accumulation of antioxidants and further study needs to be carried on about SSJHT.

  • The purpose of this study was to develop lesson plans and teaching materials applying practical reasoning instruction for the 7th home economics curriculum content, and to test the effect of practical reasoning instruction on morality of middle school students. This study is a quasi-experimental research with a pretest-posttest design. Practical reasoning instruction for experimental group and traditionally lecture oriented instruction for comparison group were input, and tested the statistical differences between two groups before and after the treatment. The subjects for this study were 8th grade students of a middle school located in Kwangju city. Two classes of 76 students homogeneous in characteristics and academic record for each experimental and comparison group were assigned. Instrument used for this study was a revised moral indicator, that was developed by KEDI(2001). Spss/win for 10.0 statistics program was used for analysis of data. ANCOVA was done for testing statistical difference between pretest and posttest of experiment group and comparison group. Result of study which showed statistically significant difference between groups were:1. Virtue of "responsibility for words and deeds"(from 3.22 to 3.61 for experimental group and from 3.27 to 3.26 for comparison group) in domain of responsibility and cooperation, and virtue of "punctuality"(from 3.59 to 3.76 for experimental group and from 3.41 to 3.28 for comparison group) in domain of trustworthiness, 2. Virtue of "conversation etiquette"(from 3.47 to 3.67 for experimental group and from 3.28 to 3.31 for comparison group) in domain of caring for others, 3. Virtue of "forgiveness other′s mistakes"(from 3.32 to 3.65 for experimental group and from 3.33 to 3.25 for comparison group) in domain of kindness, concession, forgiveness, and virtue of "volunteering activity"(from 2.89 to 3.71 for experimental group and from 3.36 to 3.45 for comparison group) in domain of compassion and service, 4. Virtue of "equip the convenient facility for handicapped"(from 4.19 to 4.29 for experimental group and from 4.17 to 3.91 for comparison group) in domain of equality and human rights, virtue of "recovering selfness for own community"(from 2.34 to 2.79 for experimental group and from 2.14 to 2.29 for comparison group), virtue of "opposing way of accomplishing purpose by an means"(from 3.27 to 3.31 for experimental group and from 3.47 to 3.05 for comparison group), virtue of "opposing election of considering acquaintance"(from 3.35 to 3.56 for experimental group and from 3.12 to 3.14 for comparison group) in domain of fairness, and virtue of "eradication of military force or violence among countries"(from 3.49 to 3.57 for experimental group and from 3.38 to 3.05 for comparison group) in domain of love for humanity. The morality of experimental group was improved more than that of comparison group in all of above items. From the results of this study, following conclusion was drawn. Practical reasoning instruction in home economics is effective in raising students′ virtue and value of responsibility in words and deeds, trustworthiness in punctuality, courtesy of not interrupting conversation, forgiveness of other′s mistakes, volunteering activity, equity for handicapped, fairness opposing selfness for own community, fairness opposing way of accomplishing purpose by all means, fairness opposing election of considering acquaintance, and love for humanity opposing war.

  • The purpose of this study was to examine: (1) the relationships among internalization of sociocultural attitudes toward appearance, body comparison, and body dissatisfaction in adolescent girls; and (2) whether or not body comparison mediates the relationship between internalization of sociocultural attitudes toward appearance and body dissatisfaction. The participants consisted of 291 girls from fifth through ninth grades. The data were collected by means of questionnaires given in classroom settings. The findings are as follows: there are significant bivariate correlations among internalization of sociocultural attitudes toward appearance, body comparison, and body dissatisfaction. Furthermore, body comparison partially mediates the relationship between internalization of sociocultural attitude towards appearance and body dissatisfaction. These results seem to indicate that the idea that there are multiple standards of beauty and individuality for every person should be promoted, and this in turn could lower the risk of body dissatisfaction among adolescent girls.
