Purpose: The purpose of this study is to examine the effects of a resistance band training program on body composition, physical fitness, and health promotion behavior in nursing students. Method: This study has a one-group pretest-posttest design to examine the change in body composition, physical fitness, and health-promoting lifestyle profile after participation in the resistance band training program. Training consisted of hands-based exercises using an elastic resistance band for ten weeks. Participants performed the resistance band training two days per week with a sports trainer, and 30 minutes self-training three days per week. The participants were 21 freshmen in nursing. Results: Mean age of the participants was 20.9 years, and 61.9% were not satisfied with their body shape. After the training program, muscle mass, muscular endurance, and balance of the body were significantly improved. In health promoting lifestyle profile, categories of physical activity, health responsibility, and stress management showed a significant increase. Conclusion: Results of this study suggested that exercising with a resistance band improved body composition, physical fitness, and health promoting behavior in the nursing students. We propose that resistance band training should be suitable for those who have the environment with limitation of time and space.

Purpose: This study was conducted in order to closely examine the effects on bone mineral density and health promotion behaviors following the intervention of a 20-week Thera band exercise program targeting elderly women. Methods: This study is a pseudo-experimental research with a pre-and-post design in a single group that examined the effects after the intervention of Thera Band Exercise for 20 weeks targeting 31 elderly women over 60 years of age who visit a Senior Welfare Center located in K city. It analyzed subjects' general characteristics using error and percentage, health promotion behavior, and a bone density aspect using the mean and standard deviation, as well as a change in the health promotion behavior and bone density, before and after exercise with Paired t-test by using the SPSS 18.0 program. Results: The effect of the Thera band exercise program on bone mineral density was reduced (t=8.140, p<.001) gradually after 20 weeks of exercise compared to the pre-exercise period. The health promotion behavior before and after exercise showed the significantly increasing outcomes (t=3.26, p=.003). Conclusion: There is a limitation to a direct rise in bone mineral density with the use of Thera band exercise intervention in the elderly. A change in health promotion behavior before and after exercise increased significantly. Thus, it was confirmed that taking exercise leads to a gradual rise in health promotion behavior. Hence, it understood that continuous exercise is useful and brings about a positive change in promoting health maintenance in elderly women.

It is known that gamma-band activity (GBA) and phase synchrony (GBPS) are induced by emotional visual stimuli. However, the characteristics of GBA and GBPS according to different emotional states have not been identified. The purpose of this study is to investigate the changes in gamma-band neuronal synchronization induced by positive and negative emotional visual stimuli using electroencephalograms (EEGs). Thirteen healthy male subjects have participated in the experiment. The induced spectral power in gamma-band was the highest for negative stimuli, and the lowest for neutral stimuli in 300-2,000 ms after the stimulus onset. The inter-regional phase synchronization in gamma-band was increased in 500-2,000 ms, mainly between the bilateral frontal regions and the parieto-occipital regions. Larger number of significant connections were found by negative stimuli compared to positive ones. Judging from temporal and spatial characteristics of the gamma-band activity and phase synchrony increases, the results may imply that affective visual stimuli cause stronger memory encoding than non-emotional stimuli, and this effect is more significant for negative emotional stimuli than positive ones.

Purpose: This study aims to compare the effect on balance during core and ankle muscle strengthening exercises using the Thera-Band. Methods: 21 healthy college students were recruited. The participants were divided into a core strengthening group (CSG), an ankle strengthening group (ASG), and a non-exercise group (NEG). CSG and ASG were performed twice a week for a total of 4 weeks, and static and dynamic balance were measured before and after the intervention. The static balance were measured as stability index and weight distribution index using Tetrax^®. The dynamic balance was measured in each direction by the Y balance test. The Thera-Band intensity was increased after 2 weeks of exercise, and the exercise was subsequently performed. Results: Participants showed static balance with Tetrax^®, a significant difference was noted between normal eye closes and pillow with eye closes in ASG (p<0.05). In the case of dynamic balance with the Y balance test, a significant difference was observed in posterolateral direction (PL) and composite score (CS) between each group for the pre- and post-intervention differences (p<0.05). A significant difference was observed between PL and CS in CSG (p<0.05). Conclusion: These findings show that the progressive Thera-Band exercise had a positive effect on balance abilities. It was confirmed that core strengthening was effective for dynamic balance, and ankle strengthening was effective for static balance.

Extract of DNA for analysis of fragile X syndrome is usually performed by blood, the researches using hair root as specimen have been gradually spread. In this study, analyze fra X gene of the patients in mentally retarded children facilities was conducted using hair root DNA with molecular biologic test (PCR). The number of total subjects was 24, boys were 12, the average age was $17({\pm}3)$, and girls were 12, the average age was $18({\pm}2)$. In girls, normal size of band of 222 bp appeared in all lanes. Also, in all lanes except control in 517 bp, micro band appeared. Moreover, with appearance of band of 1198bp in lanes 2, 3, 4, 5, it is estimated that it is the band of full mutation whose CGG repeated sequences are more than 200. But it showed the peculiarity that it appeared with normal band in all the same lanes, thus it is not reasonable to judge it is the band of full mutation and further studies are needed. These results appeared in 50%, 6 of 12 mentally retarded girls. As the result of mentally retarded boys, normal band appeared in about 222 bp in control, however in experiment group, normal band did not appear. In 43%, 7 out of 12 boys, band did not either appeared in 1198bp, which showed different patterns from that of girls.

We tried to investigate the changes in cortical activities according to emotional valence states during watching video clips. We examined the neural basis of two emotional states (positive and negative) using spectral power analysis and brain functional connectivity analysis of cortical current density time-series reconstructed from high-density electroencephalograms (EEGs). Fifteen healthy participants viewed a series of thirty-two 2 min emotional video clips. Sixty-four channel EEGs were recorded. Distributed cortical sources were reconstructed using weighted minimum norm estimation. The temporal and spatial characteristics of spectral source powers showing significant differences between positive and negative emotion were examined. Also, correlations between gamma-band activities and affective valence ratings were determined. We observed the changes of cortical current density time-series according to emotional states modulated by video clip. Gamma-band activities showed significant difference between emotional states for thirty seconds at the middle and the latter half of the video clip, mainly in prefrontal area. It was also significantly anti-correlated with the self-ratings of emotional valence. In addition, the gamma-band activities in frontal and temporal areas were strongly phase-synchronized, more strongly for negative emotional states. Cortical activities in frontal and temporal areas showed high spectral power and inter-regional phase synchronization in gamma-band during negative emotional states. It is inferred that the higher amygdala activation induced by negative stimuli resulted in strong emotional effects and caused strong local and global synchronization of neural activities in gamma-band in frontal and temporal areas.

The purpose of this study is to observe the change in gamma-band cortical activities (GBAs) due to task difficulty. Event-related potential and gamma-band activity were investigated using electroencephalograms recorded during auditory oddball tasks with two difficulty levels. For more difficult task, the amplitude of P300 decreased and the peak latency of P300 was delayed significantly compared to easier task. The induced GBA decreased considerably during the P300 latency period and the peak latency of the induced GBA was delayed for more difficult task. The results imply that the difficulty-related change in cortical information processing may be implemented as a change in the strength of local neuronal association.
