Purpose: With low birth rates and aging population problems in Korea, the number of foreign workers grows rapidly. The purpose of this study was to identify factors influencing physical activity of foreign workers based on a Health Promotion Model by examining relationships between acculturation, perceived benefits, perceived barriers, exercise self-efficacy, activity-related affect, social support, and physical activity. Methods: The participants were foreign workers aged 18 to 60 who were employed at eight shipyards. A questionnaire was distributed to 216 participants. Results: As a result of the multivariate ordinal logistic regression analysis, factors affecting physical activity of foreign workers were perceived benefits (B=.65, 95% CI=0.08~1.22), exercise self-efficacy (B=.16, 95% CI=0.05~0.26), integration (B=.41 95% CI=0.14~0.69), and social support for physical activity (B=.48, 95% CI=0.12~0.83). The total explanatory power was 17.7% (x²=41.95, p<.001). Conclusion: Based on these results, there is a need to develop a customized program to increase physical activities of foreign workers by enhancing integration, perceived benefits, exercise self-efficacy and social support.

This study was carried out to verify the accuracy of fitness tracking devices in monitoring heart rate and energy consumption and to contribute to the development of a forest exercise program that can recommend the intensity and amount of forest exercises based on personal health-related data and provide monitoring and feedback on forest exercises. Among several commercially available wearable devices, Fitbit was selected for the research, as it provides Open API and data collected by Fitbit can be utilized by third parties to develop programs. Fitbit provides users with various information collected during forest exercises including exercise time and distance, heart rate, energy consumption, as well as the altitude and slope of forests collected by GPS. However, in order to verify the usability of the heart rate and energy consumption data collected by Fitbit in forest, the accuracy of heart rate and energy consumption were verified by comparing the data collected by Fitbit and reference. In this study, 13 middle-aged women were participated, and it was found that the heart rate measured by Fitbit showed a very low error rate and high correlation with that measured by the reference. The energy consumption measured by Fitbit was not significantly different from that measured in the reference, but the error rate was slightly higher. However, there was high correlation between the results measured by Fibit and the reference, therefore, it can be concluded that Fitbit can be utilized in developing actual forest exercise programs.

In this paper, we introduce an upper extremity rehabilitation robot, NREH (NRC End-effector based Rehabilitation arm at Home). Through NREH, stroke survivors could continuously exercise their upper extremities at home. NREH allows a user to hold the handle of the end-effector of the robot arm. NREH is a end-effector-based robot that moves the arm on a two-dimensional plane, but the tilt angle can be adjusted to mimic a movement similar to that in a three-dimensional space. Depending on the tilting angle, it is possible to perform customized exercises that can adjust the difficulty for each user. The user can sit down facing the robot and perform exercises such as arm reaching. When the user sits 90 degrees sideways, the user can also exercise their arms on a plane parallel to the sagittal plane. NREH was designed to be as simple as possible considering its use at home. By applying error augmentation, the exercise effect can be increased, and assistance force or resistance force can be applied as needed. Using an encoder on two actuators and a force/torque sensor on the end-effector, NREH can continuously collect and analyze the user's movement data.

While the short term effect of diet and exercise therapy has been proven, there has still been a problem of its long term effect. So, researchers has utilized behaviour modification therapy. It is expected to lead to natural weight loss by modifying wrong dietary life patterns and practices. However, this approach has turned out to be a more effective method for weight maintenance than loss of weight. In spite of its strength, as a matter of fact, persistent and continuous effort for weight management has not worked properly. This study proposes an artificial intelligence approach with the advantages of behaviour modification therapy, overcoming current approaches which is goal-driven and too uniform. For this, we plan to develop a health management program in which users get the messages that are customized for themselves according to different situations so that it can promotes persistent effort for exercise. Here, customized messages are handled by AI techniques, which eventually promotes soft persuasion, encouragement, and motivation.

In this study, a total of 32 individual musculoskeletal examinations were performed to prevent sarcopenia through squatting exercises and corrective exercises in the elderly, and then squatting exercises and corrective exercises were performed twice a week for 12 weeks to apply and improve various exercise programs, and the following results were obtained. Body composition was significantly increased in skeletal muscle mass and basal metabolism after 12 weeks compared to before participation in the exercise program, and static postural balance was significantly improved in front shoulder, pelvic balance and deflection, left leg medial and lateral cervical and thoracic spine, and pelvic tilt after 12 weeks. Dynamic postural balance showed that the composite imbalance index, excessive upper body lean, lumbar lordosis or kyphosis, and single knee tilt and drop were all highly significant postural balances after 12 weeks. As shown in this study, the variety and precise analysis of exercise prescriptions for customized exercise programs for the elderly is very important, and it is necessary to pay attention to research on the maintenance and promotion of elderly health through practical applications in the field.

PURPOSE: This study was conducted to investigate the effects of non-elastic and elastic tapes on pain, craniovertebral angle, and balance in forward head posture (FHP) patients. METHODS: A total of 44 adults with FHP were randomly assigned to a group that performed a stretching exercise after non-elastic taping (n = 22) and another group that performed the stretching exercise after elastic taping (n = 22), respectively. The stretching exercise was performed five times a week for 30 minutes per session. The visual analogue scale was used to compare neck pain, the craniovertebral angle was measured to compare alignment, and the limit of stability was measured to compare balance. RESULTS: The groups that performed the stretching exercise after both elastic and non-elastic taping showed significant positive changes in pain and the craniovertebral angle of the head in pre- post measurements (p < .05). In the follow-up test for the pain and craniovertebral angle, there was no significant difference from the post-test in the non-elastic group (p > .05), but a significant difference was seen in the elastic group (p < .05). CONCLUSION: Stretching exercises with taping for patients with a FHP are more effective in improving pain and alignment. However, the short-duration tape application did not affect the balancing ability. When the non-elastic tape was used, the effect lasted longer than that of the elastic tape, and pain relief was effective in the case of the elastic tape. Therefore, tape therapy would be more effective if customized according to the patient's condition.

In order to manage the correct posture in daily life, it is necessary to evaluate the objective posture and appropriate prescription and management. The posture evaluation program is widely used as a method to evaluate posture relatively easily and safely. However, the existing posture evaluation program is evaluated by utilizing the position of the skeletal system, but lacks feedback on the result of the evaluation because the muscle information causing the posture is lacking and the efficiency of the program is decreased. Therefore, we will improve the existing posture evaluation program and design the system that helps the correct posture management by the appropriate exercise prescription based on the feedback that the server measures and stores the evaluation result through the SOAP message.
