This study of the Wholeness Program relevant to dementia behavior and verification of buffering effects. For the purpose of this, among those who were attending Day Care Centers belonging to Seniors Welfare Center of M1 and M2 located in Seoul. Among those who met all these requirements, 40 senior citizens were finally selected. After carrying out a preliminary test to the selected subjects, 20 elderly of Seniors Welfare Center of M1 were randomly placed as an experimental group, while other 20 people of Seniors Welfare Center of M2, as a control group. The Wholeness Program relevant to dementia behavior was carried out from March 14 to May 30 of 2016, for 12 weeks, twice a week. As for the measurement tool, this study depended on the Korean version of Mini Mental State Examination (MMSE-K), the Korean version of Modified Barthel Index (K-MBI) and the Korean version of Geriatric Depression Scale (GDS-K). While the elderly were participating in the Wholeness Program relevant to dementia behavior, they were measured two times in total, before and after the participation in dementia behavior. Based on SPSS-PC (version 21.0), firstly, independent t-test was carried out to understand the homogeneity between the experimental group and the control group. Secondly, matched-pair t-test was carried out between preliminary test and post-test to inquire into the effects of MMSE-K, K-MBI and GDS-K. Thirdly, ANOVA was conducted to confirm the variation (change amount) between preliminary test and post-test. According to the survey results, the Wholeness Program relevant to dementia behavior of the elderly shows overall effects in all spheres of changes of cognitive ability (MMSE-K), changes of physical capacity (K-MBI) and changes of depression level (GDS-K).

This study aimed to analyze PDH(Pyruvate dehydrogenase) and protein expression of PDK4(Pyruvate dehydrogenase kinase 4), PDP1(PDH phosphatase 1), enzymes that are involved in the activation of PDH, in skeletal muscle and to investigate the concentration of thiamine administration in liver and muscle following 4 weeks of endurance training. Methods : 6 weeks old male ICR mice were divided into two groups: sedentary group (CON, n=10; TH, n=10), and exercise group (EX, n=10, THEX, n=10). Thiamine(thiamine tetrahydrofurfuryl disulfide: TTFD) TTFD was orally administrated into TH and THEX groups in 50mg/kg body weight for 4 weeks. Treadmill training was performed in EX and THEX groups at about 70% of VO2max for 5 times a week for 4 weeks. Results : In this study, the concentration of glycogen was significantly increased following 4 weeks of endurance training, but a significant difference was not found following thiamine administration. Similarly, there was a significant effect of the training on PDH and the expression of PDK4 and PDP1 as PDH was increased by about 40% along with the increase in PDK4 and PDP1. However, there was no significant difference found between the groups following thiamine administration. Discussion : This result shows that there was no synergistic effect of thiamine administration, potentially due to adaptation of skeletal muscle from a long-term endurance training. Therefore, it will be necessary to consider the intake timing of thiamine and to analyze proteins that are related to PDH following the administration of complex carbohydrates.

The purpose of this study is to identify the effects of PPARβ/δ over-expression on PGC-1α mRNA and protein stability after single bout of swimming exercise in mice skeletal muscle. Empty vector (EV) or PPARβ/δ was over-expressed in tibialis anterior(TA) using electroporation(EPO) technique to compare with non-treatment muscle(control; Con). TA muscles were dissected at 0h, 24h or 54h after termination of exercise. PGC-1α mRNA in Con, EV and PPARβ/δ over-expressed muscles were increased 6.8 fold (p<.001), 6.2 fold(p<.001) and 7.1 fold(p<.001), respectively, than sedentary(Sed) group at 0h after exercise and then reverted to Sed group levels at 24h and 54h after termination of exercise. PGC-1α and PGC-1α ubiquitination in EV treated muscles were increased 2.2 fold and 1.74 fold, respectively, than Sed group at 24h after termination of exercise, and then reverted to Sed group levels at 54h after termination of exercise. PGC-1α in PPARβ/δ over-expressed muscles at 24h and 54h after termination of exercise were increased 2.5 fold and 2.2 fold, respectively, than Sed group, but PGC-1α ubiquitination was not increased at 24h and 54h after termination of exercise. Our results indicate that PPARβ/δ over-expression does not increase PGC-1α mRNA stability, but increase PGC-1α protein stability through post-translation mechanism after termination of exercise.

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.

The purpose of this study was to identify the characteristics between athletes and non-athletes with eating disorders (ED)/disordered eating(DE) and to investigate predictors for ED/DE. 376 female collegiate athletes and 567 college women participated in the study. After using subject selection criteria to detect ED/DE, 243 athletes were considered as either ED (n=22) or DE (n=221). In the non-athletes group, 37 cases of ED and 242 cases of DE were detected. Along with the EDEQ and EDI-2, participants completed a demographic questionnaire, SATAQ, and RSES. The results indicated that the mean seperation between the two groups with ED existed in seven variables including BMI perceived, BMI ideal, EDEQ mean, eating scale, weight scale, perfectionism, and self-esteem. In addition, the means of six variables including BMI perceived, BMI ideal, perfectionism, SATAQ score, awareness, and self-esteem were significantly different between the two groups with DE. Significant predictors for ED/DE were drive for thinness and self-esteem in the non athletes while drive for thinness, body dissatisfaction, self-esteem, internalization, and perfectionism were the predictors in the athletes within the ED/DE group. The results suggest that drive for thinness and self-esteem were the essential predictors for ED/DE in the two groups. in the athletes with ED/DE, the predictors were more complicated than those in the non-athletes with ED/DE.

The purpose of this study was to establish unified standards on the scope of protection of choreographic works and to suggest methods for the protection of choreography copyright. 20 experts was selected among dance experts or copyright experts and depth interview method, Delphi method and AHP analysis were used. The result was summarized as follows : First, 50 percents of the experts thought pure dance works and popular dance works should be protected by same standard, while 45 percents of the experts suggested different standard. Second, 55 percents of the experts claimed required fixation on certain medium, while 40 percents did not claim required fixation but only expression. Requirement of originality was to independently create choreography and to reflect creative characteristic(65%). 70 percents of experts were positive on defining dance choreography as independent work, while 25 percents were negative. Elements of the choreography protection scope were in following order of importance: pattern of movement, creative and concrete plot, combination of movements and steps, and movement pattern with specific space. Third, methods for the protection of dance copyright in hierarchical classification were in following order of importance : 'copyright education', 'activation of organization of dance copyright trust management', 'choreography registration' and 'inducement of social concern. Fourth, 'Active participation of dance copyright trust management organization' was thought as the most important development plan. 'Improvement of dancers' awareness of copyright', 'inducement of choreography registration', and 'reinforcement of copyright education' followed in order.
