The aim of this study is to identify the appropriate movement for maintaining postural balance during Front Kick and Turning Side Kick motions. To do so, ten Taekwondo athletes: five skilled players(S, body mass: $65.0{\pm}5.8kg$, height: $172.3{\pm}3.7cm$, age: $20.0{\pm}1.2yrs$, career: $9.0{\pm}1.9yrs$) and five less-skilled players(LS, body mass: $67.1{\pm}5.5kg$, height: $173.2{\pm}5.1cm$, age: $19.4{\pm}1.7yrs$, career: $9.6{\pm}1.7yrs$) participated in this study. A three-dimensional motion analysis was performed on the participants using eight infrared cameras and two force plate(sampling frequency of 200 Hz and 2000 Hz for S and LS players, respectively). The participants' motions were divided into: a front-kick phase(P1) and a turning-side-kick phase(P2). For P2(p<.05), the range and root mean square(RMS) of the ground reaction torque and the M-L mean velocity of COP were greater for LS than for S; similarly, for P2(p<.05), the M-L range, A-P range, and velocity of the COP were greater for LS than for S. Further, the M-L range and maximum velocity of the COP was greater for failure than for success(p<.05). The femoral biceps muscle for bending the knee joint was significantly stronger in S than in LS(p<.05). It is expected that these results will be useful in developing a training program for improving the balance and stability of Taekwondo poomsae athletes and improve their front-kick and turning-side-kick motions.

The purpose of this study is to design appropriate digital tools for the production of makeup designs. In this study, we used a three-dimensional facial avatar simulation program developed by the Electronics and Telecommunications Research. This study is based on the creation of three-dimensional CG digital art of facial avatar makeup, produced by using simulation technology. First, the actual application and the tools for digital-optimization and media features were created, leading to the research and cleanup. Second, the theoretical background was applied to the formative elements of oriental colors in the designing process. Makeup design elements include point, line, surface, color, and texture. In this study, effective makeup design was interpreted to be based on the representation of particular elements, notably the design principles of balance, proportion, rhythm, repetition, emphasis, contrast, harmony, and unity. In Asia, design is based on the visibility of red, blue, black, yellow, and white-the colors of the five elements-and the use of points, lines, and shapes. This study was recently under scrutiny in relations to digital simulation and various three-dimensional designs, in terms of how to take advantage of a wide range of applications, and how to apply the findings through media and the dissemination of basic research. This study applies the characteristics of the limited existing stereoscopic three-dimensional and digital simulation programs in order to take advantage of the empirical research, providing a basis to implement this research in a meaningful way. A follow-up study is needed to extend these findings and theoretical foundation through continuous observation and in-depth technical development and research.

PURPOSE: Strengthening training is effective at improving the function of stroke patients. This study was conducted to compare the effects of exercise intensity on walking, balancing ability, and blood glucose in stroke patients with type 2 diabetes mellitus and to suggest more effective exercise intensity for stroke patients. METHODS: Twenty-two patients with type 2 diabetes mellitus were divided into an experimental group (n=11) and a control group (n=11). In the experimental group, a 40-70% strength of 1RM exercise program was applied for 40 minutes a day, three times a week for 4 weeks. The control group received a 50% intensity of 1RM for the same number and duration of interventions as the experimental group. RESULTS: Both the experimental group and the control group showed significant improvement in the gait function, balance ability, and blood glucose level after the intervention compared to before the intervention. In the FGA (functional gait assessment), the experimental group showed a 52.4% greater increase than the control group, and the fasting blood glucose level was 16.7% greater in the experimental group than the control group. CONCLUSION: The strengthening exercise program, which gradually increases exercise intensity, seems to be effective at improving the function of stroke patients with type 2 diabetes.

Background: Self-checked monitoring home exercises are recommended for preventing falls among people with Parkinson's disease. However, as these home exercises are performed autonomously by patients without professional management, their accuracy and efficiency can be compromised. Objective: To investigate the effects of providing regular training sessions to patients and caregivers and of patient self-monitoring of exercise performance following the implementation of a self-checked monitoring exercise program for people with Parkinson's disease. Design: Randomized Pretest-Posttest Control Group Design. Methods: We provided regular self-checked monitoring home exercise and general home exercise programs to 30 participants for 12 weeks. Once a month at the first, fifth, and ninth-week sessions, a rehabilitation team attended the Parkinson's group education. In addition to the subject in the experimental group perform the home exercises program to provide feedback regarding the home exercises program and to carry out a self-monitoring checklist performance for 12 weeks. Results: The 10 m walk test, functional reach test, and sit to stand test and the modified Barthel index significantly improved in the self-checked monitoring home exercise group. Conclusion: These results suggest that self-checked home exercise programs, which facilitate safety and consistent performance of exercises at home, are beneficial for people with Parkinson's disease.

Background: In the stroke patients with the characteristics of hemiplegic gait, turning direction of the affected and unaffected side influences turning time. Therefore, it is important to investigate the walking response to turning directions in stroke patients. Objects: This study aimed to measure the walking time while turning direction in hemiplegic patients depending on balance ability measured by Berg Balance Scale. Methods: A group of forty-five subjects with stroke (Berg Balance Scale score${\geq}46$ were twenty-eight, Berg Balance Scale score${\leq}45$ were seventeen) were enrolled in this study. Subjects were asked to perform the Timed Up and Go test. Testing indications included two directions for turning in each subject. These indications were for turning toward the affected and unaffected side in stroke patients. The duration of total analysis duration, sit to stand phase, stand to sit phase, mid-turning phase, and end turning phase were recorded. The obtained data were analyzed by using paired t-test and Wilcoxon signed rank test in the group that are below and above 45 points of Berg Balance Scale score. The significance level was set at ${\alpha}=.05$. Results: There were significant increase time in the analysis duration and end turning phase duration while subjects were turned the unaffected side in stroke patients that presented a Berg Balance Scale score${\leq}45$ (p<.05). However, the comparison between the affected side and the unaffected side in the stroke patients with Berg Balance Scale score${\geq}46$, revealed no significant differences of the measured parameters. Conclusion: This finding should be suggested in the specific definition of turning direction for evaluation with Timed Up and Go test in the Berg Balance Scale score${\leq}45$, and other intervention for hemiplegic patients need to be suggested the direction of turning during walking training program.

This study aims to draw implications by analyzing the direction of the reorganization of French teacher policy focusing on ESPE which was introduced in 2013 according to the flow of French education reform. When looking at the major changes in the French teacher training system, three revisions have been made over the last 25 years and starting from IUFM introduced in 1991 and through in 2009, ESPE, a new teacher training institute, has been introduced in 2013 and been running. ESPE is an independent professional teacher training institution for educating teachers (from kindergarten to university) as well as education specialists and the understanding of ESPE has a significance in that it can see the direction of reform of French teacher policy in the fact that all advantages of the former system is succeed at maximum and the disadvantages are complemented. When looking at the major reorganization direction of French teacher policy, first, it has strengthened its position as a research teacher by connecting teacher training with the master's degree program. Second, it pursued the balance between theoretical education and field training in teacher training. Third, eligibility criteria of teacher training become diversified and it's downgrading from master degree to bachelor degree. Fourth, teacher training, teacher recruitment exam, master degree in teaching and teacher certification are linked each other. Fifth, teacher training is made in two aspects, teachers as well as education specialists. In conclusion, French teacher policy has a great significance in terms of the fact that the will of reform improving the quality of education ultimately through establishing the status as research teacher and improving the quality of teachers can be seen.

Tai Chi is a slow and gentle exercise which is suitable for obese women with chronic diseases. Tai Chi can improve the health of a senior without exacerbating existing impairments, including obese patients. The purpose of this study was to evaluate the effects of different types of Tai Chi exercise on blood variables (glucose, cholesterol, TG, HDL, LDL, cortisol) and physical fitness (muscle strength, flexibility, muscle endurance, agility, balance). Thirty obese women were recruited from a public health center. They were divided into Yang style (YS: n=15) and 12 (12KS: n=15). The Tai Chi exercise group participated in a training program for 12 weeks (3times/week). There was significant improvement in muscle strength, flexibility, and muscle endurance in both groups. Agility was significantly increased in YS, more than in 12KS. However, there was no improvement in balance in both groups. There was significant improvement in cholesterol, HDL, LDL, and cortisol in both groups. However there was no improvement in blood glucose levels in either group. From the results, there was no significant difference in either Tai Chi exercises. The Tai Chi exercise program was effective in improving cholesterol related variables and physical fitness, except balance, in both groups. Further study is needed in this area.
