PURPOSE: This study was conducted to investigate the effects of combined Joint Mobilization and Functional Electrical Stimulation on Muscle Activation and Mobility of ankle joints in stroke patients and their Modified Functional Reach Test (MFRT) results. METHODS: A total of 26 patients with stroke were randomly selected for enrollment in this study. (1) Functional Electrical Stimulation (FES) (2) combined Joint Mobilization and FES. An EMG system was used to measure tibialis anterior and gastrocnemius activities. Range Of Motion (ROM) of Ankle Joint and MFRT for Dynamic Balance. Pre and post intervention results were compared by paired-t-tests and differences in changes after intervention between groups were identified by the independent t-test. RESULTS: The muscle activation, ROM, and MFRT differed significantly in the experimental group (p<.05). The ROM was significantly different for the active dorsiflexion pre and post intervention in the group that received FES alone (p<.05). CONCLUSION: The results of this study suggest use of a systematic program of proactive posture control to prevent dysfunction when planning interventions for ankle joints can help stroke patients walk efficiently.

Purpose: The purpose of this study was to determine the effects of functional insole application using a hallux point on dynamic balance. Methods: Twenty-nine participated in this study. The experiment investigated changes in dynamic balance with the use of a functional insole that emphasized the hallux point. After explaining the experiment to the subjects, the Y-balance test was conducted to measure dynamic balance before the insole was applied. The test was then repeated after the functional insole with the hallux point was. Paired t-tests were used to analyze the statistical differences before and after the application of the functional insole with the hallux point. Results: The functional insole that emphasizes the hallux point significantly increased the distance in the anterior (p<0.05), posteromedial (p<0.05), posterolateral (p<0.05) directions as well as the composite score measured by the Y-balance test compared to before the insole application. Conclusion: The use of a functional insole that emphasizes the hallux point can help the foot pronate during dynamic balance, thereby improving balance through the control of the sole.

Background: The multiple hop test is an active performance test that has been commonly used to assess individuals with functional ankle instability. Previous studies have suggested that insufficiency of dynamic postural stability and passive stability during dynamic activities can have an influence on performance in the multiple hop test. However, no study has investigated the effects of dynamic postural stability training and ankle bracing on multiple hop test performance in individuals with functional ankle instability. Objects: The purpose of this study was to compare the immediate effects of dynamic postural stability training versus ankle bracing in the performance of the multiple hop test for participants with functional ankle instability. Methods: Twenty-nine participants with functional ankle instability who scored below 24 in the Cumberland Ankle Instability Tool were selected. The participants were randomly divided into two groups: a dynamic postural stability training group (n1=14) and an ankle bracing control group ($n_2=15$). The multiple hop tests were performed before and after applying each intervention. Dynamic postural stability training was performed using visual-feedback-based balance-training equipment; participants in this group were asked to perform a heel raise in a standing position while watching the centering of their forefoot pressure to prevent excessive ankle inversion. Ankle bracing was applied in the control group. Results: When comparing the pre- and post-intervention period for both groups, both methods significantly improved the results of the multiple hop test (p<.05). However, no significant differences were shown between the dynamic postural stability training and ankle bracing groups (p>.05). Conclusion: Both dynamic postural stability training and ankle bracing showed significant improvement (2.85 seconds and 2.05 seconds, respectively) in test performance. Further study is needed to determine the long-term effects of dynamic postural stability training and to determine whether insufficient dynamic postural stability is a causative factor for functional ankle instability.

The purpose of this study is to figure out the effects of advertisements (functional value, sentimental value, self-expressing value) depending on the gender in regard of the attitude towards the advertisement, brand attitude, purchase intention, and the characteristic and quality of the product. From the study on the university students, there was a meaningful interaction among the independent variables in regard of attitude towards advertisement, brand attitude, purchase intention, and characteristic of the product in the four dependent measurements used for the index of advertisement effects. In terms of the attitude towards advertisements, brand attitude, purchase intention, and the characteristic of the product according to the gender and value suggestion, functional convenience was more influential for men compared to the sentimental convenience and self-expressing value. On the other hand, self-expressing value was more influential for women in terms of the advertisement effect and the characteristic of the product. The main effects depending on the gender were common in four dependent values such as attitude towards advertisement, brand attitude, purchase intention and characteristic of the product, and the average of all values was higher from women. Thereby, it can be said that women show more positive advertisement effects in terms of attitude and purchase than men. The main effects on the value suggestion were meaningfully indicated in advertisement attitude, brand attitude, and characteristic of the product except the purchase intention. Also, the functional and self-expressing value made better advertisement effect, while the sentimental value showed a comparatively lower advertisement effect. In terms of the sentimental value, a comparatively low advertisement effect was shown statistically compared to the functional and self-expressing value in all dependent values, but there was no big difference depending on the gender. That is, in terms of the sentimental value, a separate value suggesting advertisement can be more influential when it is combined with the functional value for men, and for women if it is combined with self-expressing value.

The purpose of this study is to develop functional garment wear for patients with adolescent idiopathic scoliosis (AIS) and to analyze changes in Cobb's angle and the COM of the body and the pelvis during gaits in order to identify the effects of the functional garment wear. The subjects of the study were 9 patients with adolescent idiopathic scoliosis, who wore the functional garment wear for 12 weeks 12 hours a day. As for the research methods, the scoliotic angle was measured using Cobb's angle, and the shoulder angle and the COM of the body and the pelvis during gaits for the AIS patients were calculated using five high speed infrared cameras. As a result of the study, it was found that the scoliotic angle (Cobb's angle) was reduced significantly and that the smaller the original scoliotic angle, the greater the effects. As for the shoulder motion angle, a significantly larger angle was found 12 weeks after wearing the functional garment wear, and particularly, larger shoulder motion (activity) was observed at the phase of right heel contact. As for the motion of the body and the pelvis, the moving ranges were significantly reduced after wearing the functional garment wear for 12 weeks, which stabilized gait in the patients with adolescent idiopathic scoliosis.

Background: Panax ginseng Meyer has been used as a nourishing edible herb in East Asia for thousands of years. 25-OH-PPT was first discovered as a natural rare triterpenoid saponin in ginseng stems and leaves by our group. Research found that it showed strong inhibitory effects on α-glucosidase and protein tyrosine phosphatase 1B, and protected cardiocytes (H9c2) through PI3K/Akt pathway. Methods: In the research, in order to optimize the 25-OH-PPT enrichment process, optimal macroporous resins and optimal purification conditions were studied. Meanwhile, the hypoglycemic effect and mechanism of 25-OH-PPT were evaluated by using STZ to establish insulin-dependent diabetic mice and the spontaneous type 2 diabetes DB/DB mice. Results and Conclusion: Research found that 25-OH-PPT can reduce blood glucose and enhance glucose tolerance in STZ model mice. It increases insulin sensitivity by upregulating GLUT4 and AMPK in skeletal muscle, and activating insulin signaling pathways. In DB/DB mice, 25-OH-PPT achieves hypoglycemic effects mainly by activating the insulin signaling pathway. Meanwhile, through the influence of liver inflammatory factors and lipids in serum, it can be seen that 25-OH-PPT has obvious anti-inflammatory and lipid-lowering effects. These results provide new insights into the study of ginseng as a functional food.

A functional equation is an equation which is satisfied by a function. Some elementary functional equations can be manipulated with elementary algebraic operations and functional composition only. However to solve such functional equations, somewhat critical and creative thinking ability is required, so that it is educationally worth while teaching functional equations. In this paper, we look at the origin of functional equations, and their characteristics and educational meaning and effects. We carefully suggest the use of the functional equations as a material for school mathematics education.

Objective: To investigate the efficacy and side effects of Bifidobacterium tetragenous viable bacteria tablets in treating cancer patients with functional constipation during chemotherapy. Methods: A consecutive cohort of 100 cancer patients with functional constipation were divided into two equal groups: patients in the experimental group were given Bifidobacterium tetragenous viable bacteria tablets combined with chemotherapy, while patients in the control group received chemotherapy alone. After 4 weeks, the efficacy and side effects in treating functional constipation were evaluated. Results: Constipation in 48 patients in experimental group was controlled (9 returned to normal), with a total response rate of 96%, and 1 patient reported diarrhea (2%). In contrast only 16 patients in the control group demonstrated improvement and 34 were still constipated after chemotherapy, with a response rate of 32%. The difference in response rate was statistically significant (P<0.05). Conclusion: This study suggested that Bifidobacterium tetragenous viable bacteria tablets are effective and safe in treating cancer patients with functional constipation during chemotherapy.
