Hands-on education and training is a key part of fixing and developing technology knowledge and is an inherent part of many engineering and scientific curricula. However, access to large complex training facilities, such as nuclear reactor, could be limited by various factors, such as unavailability of those facilities in the region, high traveling costs or harmonization of the schedules of hands-on E&T with theoretical lectures and with the operational schedule of the facility. To handle the issue, several success stories have been reached with the introduction of the Internet Reactor Labs (IRL). The Internet Reactor Labs can strongly contribute to accessibility of training at research reactors and can contribute to improvements in their utilization. The paper describes the development of the Internet Reactor Lab at the VR-1 reactor of the Czech Technical University in Prague. Contrary to single-purpose IRLs, it presents various modalities of online teaching and training in experimental reactor physics and reactor operation in general as well as outreach activities that have been developed in recent years.

PURPOSE: The purpose of this study was to investigate the effects of stage-based training, including core exercises, on scoliosis patients. METHODS: Two patients with scoliosis participated in the study. Both patients participated for eight months and were trained for an hour three times a week. The training program consisted of stretching and strengthening, as well as core exercises, and was divided into five stages. The Cobb angles and trunk lengths of the subjects were measured after one month, two months, and four months of training. Measurements were also taken after the subjects completed training. All of the measurements were taken using Formetric 4D. RESULTS: The Cobb's angle of subject A, which was $41^{\circ}$ before training, measured $30^{\circ}$ following training. The Cobb's angle of subject B also improved from $41^{\circ}$ prior to training to $34^{\circ}$ after training. Furthermore, the trunk lengths of both subjects improved. The trunk length of subject A increased from 438 mm to 450 mm and, and the trunk length of subject B increased from 433 mm to 458 mm. CONCLUSION: This study has shown that stage-based training and core training can be used as effective treatments for scoliosis patients.

Purpose: This study was intended to discover the effect of the turning training on figure of 8 tract on stroke patients' static and dynamic balance, as well as walking. Methods: A total of 42 stroke patients participated in this study. The training group was trained on the figure of 8 tract, while the control group was trained on the straight path for 30 minutes per day, for 4 weeks. Berg balance scale was used to measure the balance of the patients, before and after the training, and Good balance system was used to measure the sway speed and the distance of COG while standing. To measure the ability of walking, TUG and FSST were also used. Results: There were significant increases in the average score of Berg balance scale, in both groups after the training, and also significant difference between both groups were observed. The training group showed significant differences in the static balance ability, as well as anteroposterior and mediolateral sway speed. Further, there were significant increases in the dynamic balance ability, COP total distance, and TUG in both groups. The results showed more differences in comparing the control group with that of the training group. In FSST, there was no change in the control group, but there was a significant increase in the training group. Conclusion: Turning training on figure of 8 tract in stroke patients significantly increased the static and dynamic balance and walking ability. Based on the results, it can be seen that the training on the figure of 8 tract can influence the ability of balance and walking, which can lead to appropriate reactions to the change of environment and various tasks. Thus, it is assumed that turning training on figure of 8 tract as a means of improving the condition of stroke patients can be a meaningful program.

Purpose: This study examined the effects of backward walking training with task orientation on the functional walking ability of children with cerebral palsy. Methods: This study was a single-blinded, randomized controlled trial with a crossover design conducted at a single rehabilitation facility with cross-over to the other intervention arm following a two-week break. For a total of 12 children with spastic hemiplegia cerebral palsy, the forward walking training group (n=6) underwent training three times a week for three weeks, 40 minutes a day, and the backward walking training group (n=6) was also trained under the same conditions. To identify the functional walking ability, variables, such as the walking speed, stride length, and step length, were measured using a walk analyzer (OptoGait, Microgate S.r.l, Italy). Results: Both groups showed significant increases in walking speed, stride length, and step length (p<0.01). The backward walking group showed more significant improvement in the walking speed from pre- to post-test (p<0.05). The gait characteristics were similar in the two groups (stride length and step length) but the walking speed in the backward walking group showed a mean difference between the positive effects higher than the forward walking group. Conclusion: Task-oriented backward walking training, which was conducted on the ground, may be a more effective treatment approach for improving the walking functions of spastic hemiplegia children than forward walk training.

Purpose: This study was conducted to examine the effects of walking exercise training on body composition and physical fitness in middle aged women. Method: The subjects were randomly assigned into an obese walking exercise training group (n=21), a non-obese walking exercise training group (n=9), or a control group (n=10). The women in the treatment groups were then subjected to brisk walking at 50~70% of maximum heart rate twice a week for 12 weeks. The results were then analyzed by repeated measures ANOVA using SPSS 12.0 for windows. Results: Body weight, BMI, % body fat, and WC were not significantly improved in the obese walking exercise training group and the non-obese walking exercise training group. However, muscular flexibility and muscular endurance were significantly improved in each of these groups (p<.05). Conclusion: These results indicate that 12 weeks of walking exercise training enhanced physical fitness. However, the treatment in this study did not improve the body composition of middle aged women.

Purpose : This study aimed to compare the effect of two conditions (visual and kinesthetic) of motor imagery training on static and dynamic balance. Methods : Fifteen patients with post-stroke hemiparesis volunteered to participate in this study. Two motor imagery training conditions, for 10minute trials, employed with audiotape instructions. Measurements were performed at pretest, posttest and 1-hour follow up in both static and dynamic balance. Results : Measures were significantly different both static and dynamic balance tests between treatment conditions (kinesthetic imagery more than visual imagery) at the pretest, post test, and 1-hour follow-up (p<.05). Measures of both static and dynamic balance tests, for both conditions, improved significantly from pretest to posttest (p<.05), and was maintained at 1-hour follow up. Conclusion : This study showed that both imagery training applications were effective treatment strategies for both static and dynamic balance. When comparing the two treatment conditions, kinesthetic motor imagery training was more effective than the visual motor imagery training in static and dynamic balance.

To evaluate training effect, the step exercise was loaded to three mem for nine weeks. Step score, cardiopulmonary functions and blood constituents were measured before, during and after the test exercise (50 cm-step exercise and treadmill running), and were compared with the pre-tranining values. The results were as follows: 1) By the training, Harvard step score increased remarkably, expecially in the early stage of training. 2) The post-training values of maximal oxygen uptake increased very significantly and it seemed to be due to increases of stroke volume and tissue oxygen extraction. 3) After the training, the degree of increase in expired volume was small during the treadmill exercise. 4) By the training, increasing rate of respiratory quotient lessened during the exercise and it was considered to be caused by the decreases of carbohydrate consumption and anaerobic metabolism. 5) The blood cholesterol concentrations were harldy changed with this degree of training. 6) The blood lactate level decreased during the recovery periods and the values of the recovery 0 and 5 minutes decreased remarkably, in comparison with the pre-trained values. The above results suggest that the 9 week-training of the step exercise brings about the enhancement of circulatory functions and tissue oxygen utilization, and changes of food-stuffs used during the exercise.

Purpose: The purpose of the study was to identify the effects of proprioceptive neuromuscular facilitation (PNF) training and robot rehabilitation training on trunk stability and standing balance in individuals with chronic stroke. Methods: There were 30 patients with chronic stroke, divided into two groups: 15 subjects who received PNF and robot training (the experimental group) and 15 subjects who received standard conservative training (the control group), that participated. The experimental group received treatment for 60 min: 30 min of conventional physical therapy, 15 min of PNF training, and 15 min of robot training. The control group received conventional physical therapy for 60 min. Trunk stabilization (trunk impairment scale) and standing balance (center of pressure, limit of stability, modified functional reach test, and Berg balance scale) were measured before and after intervention. Results: Within each group, both the experimental and control groups significantly improved after the intervention in all tests; however, the experimental group showed greater improvement in scores on the trunk impairment scale, the center of pressure, the limit of stability, the modified functional reach test, and the Berg balance scale. Conclusion: The study verified that PNF training and robot training had a positive influence on trunk stability and standing balance indices in patients with chronic stroke.

Purpose: The purpose of the study was to investigate the effect of a training program using virtual reality on the balance and lower muscular strength of Parkinson's disease patients. Methods: The study included 22 patients with Parkinson's disease who were arbitrarily classified into 2 groups: 11 patients in the experimental group and 11 patients in the control group. Balance was measured with the Berg balance scale (BBS), the functional reach test (FRT), one-leg stance test (OLST), and the timed up and go test (TUG); whereas, lower muscular strength was measured with the sit-to-stand test (STS). Ping-Pong, bowling, and tennis were selected for virtual reality training for the experimental group, and were performed for 30 minutes 3 times a week for 8 weeks. The control group did not undergo any of the virtual reality training programs. Results: A significant difference was observed in the BBS, FRT, OLST, TUG, and STS results within the experimental group that underwent the virtual reality training program. On the other hand, no significant difference was observed in the BBS, FRT, OLST, TUG, and STS values within the control groups. Conclusion: In conclusion, the virtual reality training program positively affects the balance and lower muscular strength in Parkinson's disease patients. This result indicates the possibility of application of the virtual reality training program to the management for Parkinson's disease patients, and highlights the need for the development and application of more efficient virtual reality training programs in the future.
