This study aimed to investigate the effects of participating in an aerobic exercise program three days a week and 50 minutes a day on dementia related factors and cognitive function in elderly women with mild dementia. For this, among 17 elderly women aged 65 and above, 10 elderly women were randomly assigned to the experimental group and 7 elderly wonmen to the control group. As a result of comparative analysis, conclusions were drawn as follows: There was a significant difference (p<.05) in the DHEA-s change between the two groups according to whether or not the aerobic exercise program was performed. Changes in cognitive function did not show any significant difference in the interaction effects of group, period, period${\times}$group. These results suggest that the aerobic exercise program did not show statistically significant effects on the dementia related factors and cognitive function changes of the elderly women with mild dementia. The reason for this is that the followings should be analyzed in more detail, but the lack of control on the daily life (diet) of the study subjects, which was considered as a limitation in this study, seems to be the biggest cause. Based on the results of this study, we hope that this study will be used as a basic data for improving the quality of dementia.

This study aims to understand the relationship between the practice of physical activity guideline for adolescents presented by government agencies and smartphone problem experience. To that end, the association between the practice of physical activity guideline and smartphone variables was analyzed by utilizing 62,225 data from "2017 Youth Health Behavior Survey" and multiple regression analysis was conducted using the SPSS 23.0 program. The analysis showed that all physical activity variables, except for "physical activity for more than 60 minutes," have negative effects on the smartphone problem experience. In addition, students who practice physical activity guideline presented by government agencies, such as aerobic exercise, muscular exercise, participation in sports clubs, and sedentary behavior, experienced less smartphone problem compared to those who did not practice, which showed significant differences in gender. According to the results of this study, it is thought that academic in-depth research using this guideline and differentiated physical activity promotion programs by gender will be possible in order to prevent smartphone addiction.

The purpose of this study was to investigated the effect of taping intervention applied to the diaphragm on the anaerobic performance in 30 seconds. 18 healthy college students were randomly divided into experimental group(KT=9) and control group(Sham=9). In both groups, pre and post measurement was performed by wingate test, and post measurement was performed with taping application after a week rest. The statistics between two groups on the rate of change pre and post were analyzed through Mann-Whitney U test. Statistically, it showed that only the average power(AP) of control group was significantly different. This means that diaphragmatic taping did not affect the performance of anaerobic exercise for 30 seconds. However, considering the increase in aerobic metabolism during long-term anaerobic exercise longer than 30 seconds, further studies on anaerobic exercise performance within various time ranges are needed.

The purpose of the study was to compare the effect of either moderate or high intensity aerobic exercise on inflammasome, M1, M2 macrophage infiltration and brown adipocyte markers in subcutaneous adipose tissue of the high fat diet-induced obese mice. The 4 weeks male C57BL/6 mice were randomly assigned to four groups: normal diet control (NC; n=10), high-fat diet control (HC; n=10), high fat diet with moderate intensity exercise (HME; n=10), or high fat diet with high intensity exercise (HIE; n=10) groups. The high fat diet was given 60% calories from fat whereas normal diet was given 18% calories from fat. The moderate intensity exercise group (HME) was set at 10m/min in the first 2 weeks, 12m/min in 3-5 weeks and 14m/min in 6-16 weeks and the high intensity exercise group (HIE) was set at 14m/min in the first 2 weeks, 17m/min in 3-5 weeks and 18m/min in 6-16 weeks. The semi quantitative reverse transcription-polymerase chain reaction (RT PCR) was used to analyze the gene expression. The moderate intensity exercise significantly reduced the expression of NLRP3, F480, CD11c and CD86. Further, the moderate intensity exercise significantly increased CD206 and $PGC1{\alpha}$, BMP7 and PRDM. The high intensity exercise significantly reduced NLRP3, CD11c and CD86. Further, the high intensity exercise significantly increased $PGC1{\alpha}$ and BMP7. In conclusion, moderate intensity exercise has more positive effects on inflammasome, M1, M2 macrophage infiltration and brown adipocyte maskers compared to high intensity exercise in high fat diet induced obese mice.

Recently, by fast industralization and development without environmental concern, our environment deterioration have being continued rapidly. Therefore, many species is placed on crisis of extinction or was already extincted by habitat destruction. In Minjujisan area, there is a plan to construct the Sport and Leisure Complex by which convert the forest conservancy district to the district of development promotion and district of sighseeing and leisure by Yongdong District. To investigate the avifauna impacts by habitat destruction, bird censuses was carried out before the Sport and Leisure Complex be construct in Minjujisan and Sokgisan area during 4-5 May, 1992 and 16-21 June, 1992. Total 229 birds of 41 species in 23 family of 9 orders were recorded during censuses. Sitta europaea amurensis was the most abundant species and Parus ater amurensis, Phylloscopus borealis xanthodryas, Parus major wladiwostokensis, Parus palustris hellmayri, and Turdus pallidus were dominant species. Accipiter nisus nisosimilis, Accipiter soloenis, and Otus scops stictonotus were found out to the natural monuments in this suvey. Halcyon pileate was observed to a rare bird in this surveyed area. Species diversity of this census was 3.381 which showed slightly higher degree than other surveyed area. The area of Minjujisan, Sokgipong, and Samdopong which have little pollution agent around there and kept away from mankind were approved the heavy avifauna area which have so many bird species. Biogeographically, the Taebaek Mountains was connected with the Sobaek Mountains through this area, therefore it was significant that many animal species could be move to each mountains ranges. The construction plan of the Sport and Leisure Complex in Minjujisan area should be restrain with concern about environmentally destruction by the Muju Resort in Dokyusan National Park which connected to that area have master plan to development the ski slopes for the 1997 Universiad with permission by the Ministry of Environment.

This research, to find the cultural identity of taekwondo, presents the historical origin of taekwondo in lights of Choi-centric theory, kwan-centric theory, karate inflow theory, and successive traditional martial arts theory. Then it investigates taekwondo's inner identity as a Korean traditional martial art according to presence, popularity, and independence, three factors of identity suggested by Tak, S. S.(2000).As a result, it reached these conclusions: First, taekwondo was formed after going through fusion of Hong Hi Choi, karate income in period of cultural severance during Japanese occupation, the first kwan leaders and Korean traditional martial arts, process of disorder and cultural reproduction. Second, taekwondo has essentially inherited and developed Korean barehanded martial arts' movements that lay stress on foot skills, and this distinguishes it from hand-skill-based Japan's karate and China's Wushu Furthermore, trunk/groin protectors and headgears are blended remarkably with taeguk patterns and traditional Colors of Five Directions. All terms rendered into pure Korean words shows the essence of Korean localization. It is therefore concluded that Koreans should, along with trying to overcome exclusive nationalism as a country of origin, build a new paradigm of establishing an identity as a global martial art sport.

The purpose of this study was to examine how combined exercise and acaiberry intake make effects on insulin and glycated hemoglobin of middle-aged women. The middle-aged women in their 40s and 50s were classified into three groups - group A which only had acaiberry intake, group B which both had acaiberry intake and combined exercise, and group C which only underwent the combined exercise. The combined exercise was held three times a week for 8 weeks, each for 60 minutes including warming up and cooling down. The aerobic exercise was carried out for 20 minutes with a treadmill walk with HRmax 50-60% and the resistance movement was carried out for 20 minutes with a strength of 50-60% based on 1RM. The participants were told to have the acaiberry drink before breakfast and dinner, by melting 5g of acaiberry powder to water. 2-way RGRM ANOVA was carried out to process the data for comparing each groups. In conclusion, the 8-weeks of combined exercise and acaiberry ingestion therapy did not improve the insulin and glycated hemoglobin. It is more likely to show clear changes in both elements with longer treatments and controlling the amount of ingestion and exercise intensity.

The objective of this study was to examine the relationship between physical activity (PA) level and functional fitness (FF) parameters in community-dwelling older adults aged 65 or above in Korea. Subjects' (M: 1,645; F: 2,394) PA level were assessed using a questionnaire. The subjects were divided into two groups: one below the recommended level of PA(LPA) and one above the recommended level (PA). PA was further classified by intensity level into medium- and high-intensity PA (MIPA and HIPA respectively) groups. FF was assessed based on six test items representing the following fitness areas: lower and upper body strength, agility and dynamic balance, flexibility, aerobic capacity, coordination, and body composition. Of the subjects, 36% met the recommended level of PA. Both MIPA and HIPA were superior to LPA in all FF items(p<.05). The HIPA group was significantly better in terms of agility and dynamic balance, coordination, and lower body strength (only in women) than was the MIPA group(p<.05). In conclusion, PA above the recommended level is needed to maintain functional fitness. In addition, HIPA seems to promote fall-related functional fitness and should be encouraged when safe and feasible.
