Objective: Dual-task walking deficits impact functional daily life, which often requires walking while performing simultaneous tasks such as talking, thinking or carrying an object. This study is to find out the latest trend of dual-task training's influence on ambulatory abilities of a stroke patient. Design: Systematic review of randomized controlled trials. Methods: This literature review was conducted in Pubmed and Sciencedirect with the follwing key words:stroke, cerebro-vascular accident, hemiplegia, gait, rehabilitation, exercise. 7 studies were chosen in findings by search tool. 3 studies were case study, 3 studies were cross sectional observational study and 1 study was randomized controlled trial. Results: It was found that stroke patients have difficulties in doing 2 motor tasks simultaneously and when they do 2 tasks, one is done in a naturally preferred activity areas. Moreover, when simply applying dual-tasks, the walking speed decreased. Meanwhile, when applying them through training, the speed increased. This showed the improvement of effective task-implementation abilities after dual-task training using task-integration models. Conclusions: In the beginning of the 2000s, dual-tasks were implemented by simply combining walking and cognition or exercise task, and the results of this study suggest that subjects with stroke have difficulty performing dual task. However, the latest trend is to let patients do the dual-task training by combining it with virtual reality. Therefore, dual task training could be performed in a safe in the environment such as virtual reality or augment reality.

Purpose: This study was conducted in order to investigate the effect on respiratory function, trunk control, and functional activities of daily living (ADL) through respiratory muscle strength training in patients with chronic stroke. Methods: Eighteen subjects who were six months post stroke participated in this study. The subjects were randomly allocated to two groups: experimental (n=10) and control (n=8). Both groups received physical therapy for five sessions, 30 minutes per week, during a period of six weeks. Subjects in the experimental group participated in an additional respiratory muscle strength training program, in which the threshold PEP device was used for 30 minutes per day, three days per week, during a period of six weeks. Results from pretest-posttest control were evaluated by pulmonary function forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), capacity of cough, trunk control, and functional ADL. Results: Significant improvement in the FEV1, PEF of pulmonary function (p<0.05), cough function (p<0.05), and trunk control (p<0.05) was observed among the groups. Conclusion: Respiratory muscle strength training improves pulmonary function, capacity of cough, and trunk control. These results suggest that respiratory muscle strength training is feasible and suitable for individuals with chronic stroke.

Purpose: This study was to delineate the structural change of neural pathway after sequential motor learning using diffusion tensor imaging (DTI). Methods: The participants were 16 healthy subjects, which were divided by training (n=8) and control (n=8) group. The task for the training was the Serial Reaction Time Task (SRTT) which was designed by Superlab program. When the 'asterisk' shows up in the 4 partition spaces on the monitor, the subject presses the correct response button as soon as possible. The training group participated in the training program of motor learning with SRTT composed of 24 digits pattern in one hour per daily through 10 days during 2 weeks. Results: In the behavioral results the training group showed significant changes in the increase of response number and the reduction of response time than those of the control group. There was significant difference in the left inferior frontal area in the fractional anisotropy (FA) map of the training group in DTI analysis. Conclusion: Motor sequential learning as like SRTT may be needed to the learning of language and visuospatial processing and may be induced for the experience-dependent structural plasticity during short period.

To investigate the effects of exercise-training on fat distribution several indicators of body fatness(percent body fat skinfolds thickness body circumference) were assessed in 128 healthy male subjects submitted to an 8-wk high intensive exercise-training. The subjects(average age=20.3$\pm$1.3 yrs) exercised 5 days/week. Daily energy intake and expenditure wee recorded. The results obtained are summarized as follows : 1) Through exercise-training lean body mass increased significantly (changes : 0.5$\pm$1.5kg; p=0.000) decreased significantly. 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$2.1mm and 0.4$\pm$1.8mm respectively. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) As a result of analyzing 12 of the fattest(top 10% of weight) and 12 of the leanest men(bot-tom 10% of weight) it indicated that there was a significant reduction of fat tissue in body composition and skinfolds thickness for the fat group. However there was no significant change for the lean groups. 4) Correlational analysis showed that predicting changes in body fat by infrared(NIR) measurement seemed to be closely associated with changes in body fat by Kim's equation and Katch's equation in young men.

Purpose: The purpose of this study was to examine changes in functional assessment measures (FAMs) and spatiotemporal gait parameters (STGPs) in healthy older adults before and after a 6-week intervention of a proprioceptive neuromuscular facilitation (PNF) training program. Methods: Thirty healthy older adults (mean age: $73.37{\pm}1.21$ age range: 65-79) were randomly assigned either to an experimental group (participating in a 6-week intervention of PNF training) or a control group (only performing daily activities). Participants in the control group did not receive any training program. Performance was assessed by recording changes in the FAMs and STGPs using functional assessment tools and GAITRite. Results: Participants in the PNF group showed significantly improved functional assessment measures and increased stride length, cadence, velocity, and step width (p<0.05). No significant differences in FAMs and STGPs were found in the control group (p>0.05). Conclusion: Participation in a PNF training program improves FAMs and STGPs, thereby increasing the ability of healthy older adults to maintain dynamic balance during functional performance and gait. These findings support the use of PNF training programs as effective fall-prevention programs for the elderly.

Daily workers in construction sites rarely receive the benefit of systematic safety and health training as they are required to move from one construction site to another in response to the start, completion, and repetition of construction works. Also, small- to medium-sized construction sites often lack the capacity to train their workers. Therefore, as in the advanced countries, basic OSH training sheme for construction workers should be conducted in the industrial-level, rather than in individual workplace-level, to make the training more effective. By doing so, only workers with the basic safety training will be able to engage in construction works. Consequently, accidents in the construction industry will decrease, as workers themselves who are at the forefront of the construction worksites are empowered to play the central role in accident prevention activities.
