Purpose: The purpose of this study was to investigate the effect of a kettlebell complex program according to the support surface on the lower extremity muscle activity and balance of baseball players. Methods: The participants were divided into two groups; unstable support surface group 1 (11 people) performed the kettlebell complex program on an unstable support surface, and stable support surface group 2 (10 people) performed the kettlebell complex program on a stable support surface. Muscle activity was measured by surface electromyography. Dynamic balance was measured with a balance-measuring equipment. A paired t-test was used to compare groups before and after the experiment. An independent t-test was performed to determine the difference in the degree of change between the two groups before and after the experiment. Results: The intragroup comparison between stable support surface group 1 and 2 showed significant differences in muscle activity and sense of balance. In the comparison between the groups, the difference in muscle activity in unstable support surface group1 was significant in the biceps femoris and rectus femoris muscles, and significant differences were also found in the sense of balance. Conclusion: These results suggest that a kettlebell exercise on an unstable support surface is more effective in improving muscle activity and sense of balance than a kettlebell exercise on a stable support surface.

This study investigated the isolation hypothesis and the buffer hypothesis of Demand-Control-Support model in relation to activity satisfaction and psychological well-being. The subjects were 300 elderly women participating in productive activity for example paid work, voluntary activity, and grancdhildren care. This research tested four hypotheses concerning the DCS model. Is there support for the isolation hypothesis, such that the lowest level of activity satisfaction is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the isolation hypothesis, such that the lowest level of psychological well-being is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on activity satisfaction? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on psychological well-being? Major results of this study were as follows. and were supported. Activity satisfaction and psychological well-being of the elderly women in isolation situation was the lowest among the sample. was supported that family support level buffered the negative impact of high strain on activity satisfaction. But was not supported. Only main effect of demand level was showed on psychological well-being.

Purpose : The purpose of this study is to examine the effect of instrumental-activity of daily living program on a patient with subacute stroke in the view of self-efficiency, motivation for rehabilitation, social support. Methods : Eight stroke patients who attended instrumental-activity of daily living program at P hospital in Busan Metropolitan City from march 2018 to January 2019 were recruited. Instrumental-activity of daily living program was offered to 8 stroke patients 1 session (at least 1 hours) a day, 5 times a week, for 4~5 weeks. The instrumental-activity of daily living program was based on occupational therapy practice framework (OTPF) and international classification of functioning, disability and health (ICF). We evaluated self-efficacy, rehabilitation motivation, social support before and after intervention. Self-efficacy was evaluated using the general self-efficacy scale. The collected data was processed using SPSS 20.0 and were analyzed using descriptive statistics, Wilcoxon signed rank test, Pearson's correlation coefficient. Results : There were statistically significant differences in self-efficiency, rehabilitation motivation, social support between before and after instrumental-activity of daily living program (p<.05). Examining the correlation between the self-efficiency, rehabilitation motivation and social support of the stroke patient, there was a correlation between the self-efficiency and social support (p<.05). Conclusion : This study showed that the instrumental-activity of daily living program have positive effects on self-efficacy, rehabilitation motivation, social support. When considering the instrumental-activity of daily living program with improved self-efficacy, rehabilitation motivation, social support of the participants, we suggest that further studies will be needed to examine more extensive instrumental-activity of daily living and rehabilitation to the society with a larger sample size.

The purpose of this study is to examine factors causing the female adolescent sexual activity. 201 female adolescents participated in this study. Each participant was classified into the sexual activity experience or non-sexual activity experience group on the basis of survey. In total, 87 female adolescents have sexual activity experience, and 114 female adolescents have non-sexual activity experience. Analysis reported that sexual activity experience group was more positive on the adolescent sexual activity than non-sexual activity experience group. Also sexual activity experience group has more peers having sexual activity and pregnancy experience than non-sexual activity experience group. And, sexual activity experience group was more coping level and lower father social support than non-sexual activity experience group. Logistic regression analysis was conducted in order to determine the extent to which the attitude on the adolescent sexual activity, peer group's sexual experiences, social support, and coping factors affected on female adolescent sexual activity. As a results, peer's sexual activity and peer's pregnancy factors were significantly associated with it. Finally based on the results, the intervention strategies were suggested.

Objectives : According to Rowe and Kahn (1998), successful aging is the combination of a low probability of disease, high functioning, and active engagement with life. The purpose of this study was to assess the relationship between active engagement with life and functioning among the community-dwelling elderly. Methods : Data were collected from Wave 2 of the Suwon Longitudinal Aging Study (SLAS), consisting of a sample of 645 persons aged 65 and older living in the community. A social activity checklist and social support inventory were used as measures of engagement with life, along with the Physical Functioning (PF) scale as a measure of functioning. The effects of social support and social activity on physical functioning, taking into account the covariates, were analyzed by hierarchical linear regression analysis. Results : Maintenance of social activity and social support were significantly associated with higher physical function, after adjusting for sociodemographic and health-related covariates. Social support appeared to be more prominent than social activity in predicting physical functioning. Conclusions : Social support and social activity are potentially modifiable factors associated with physical function in older persons. Studies examining the role social engagement may play in preventing disability are warranted.

An explanatory design was employed to identify the relationship of physical, emotional & social readjustment and social support of post hospitalized stroke patients and their caregivers. A convenient sample of 254 patients who given follow-up care at the outpatient department after discharge and 225 caregivers were recruited. Mental Status Questionnaire (MSQ), Social Support Inventory Stroke Survivors (SSISS), Illness intrusiveness(II), Instument Activity of Daily Living(IADL), Center of Epidemilogic Studies-Depression(CES-D), social activity and caregiver burden were used for measurement in this study. Results showed patient's physical level measured by IADL and psychological level measured by depression were high. But social activity was low. Cognitive function, depression & social activity were not significantly different by the posthospitalized period, but IADL was. The source of professional support was mostly the physician at the outpatient department. The family support was found significantly related to patient's depression & social activity and caregiver's subjective burden. Professional support was found significantly related to patient's IADL & depression. Illness intrusiveness as a mediating variable was a sig nificantly predicting power on patient's IADL & depression. The path analysis was used to identify the variables to predict the physical, emotional, and social status of patients. As a result, patient's age, cognitive function, illness intursiveness and professional support significantly predicted the level of IADL ; patient's cognitive function, illness intrusiveness and family support significantly predicted the level of depression ; and patient's age and family support significantly predicted the level of social activity of posthospitalized stroke patients. Based upon these results, the rehabilitation programs to reduce the illness intrusiveness and improve cognitive funtion were recommended for the readjustment of the stroke patients. This model of the readjustment of the posthospitalized stroke patients is recommended as the framework for care of the stroke patients.

Background: Using wearable passive back-support exoskeletons in workplace has attracted attention as devices that support the posture of workers, enhance their physical capabilities, and reduce physical risk factors. Objects: This study aimed to investigate the effect of a wearable passive back-support exoskeleton on the activity of the erector spinae muscles during lifting tasks at various heights. Methods: Twenty healthy adult males were selected as subjects. Electromyography (EMG) was used to assess the activity of the erector spinae muscles while performing lifting tasks at three distinct heights (30, 40, and 50 cm), with and without the application of the Wearable Passive Back Support Exoskeleton. EMG data were gathered before and after the application of the orthosis. Results: The use of the Wearable Passive Back Support Exoskeleton resulted in a significant decrease in muscle activity when lifting a 10 kg object from heights of 30 and 40 cm (p < 0.05). Additionally, there was a significant reduction in muscle activity when lifting from a height of 50 cm compared with that at lower heights (p < 0.05). Conclusion: The use of a wearable passive back-support exoskeleton led to a decrease in the activity of the erector spinae muscles during lifting tasks, irrespective of the object's height. Our results suggest that the orthosis we tested may help decrease risk of lower back injuries during lifting.

Purpose: This study aimed to investigate the correlation between trunk stabilization muscle activation and the parameters of gait analysis in healthy individuals. Methods: Thirty healthy adults (15 male, 15 female) with no history of lower back pain (LBP) or current musculoskeletal and neurological injuries were studied. Trunk stabilization muscle activation (e.g., external oblique, internal oblique, transverse abdominis, erector spinae) were assessed using surface electromyography. To analyze gait, we measured temporal parameters (e.g., gait velocity, single support phase, double support phase, swing phase, and stance phase) and a spatial parameter (e.g., H-H base of support). Results: A statistically significant correlation was found between the internal oblique, transverse abdominis, and erector spinae muscle activity and gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique muscle activity and the gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique, internal oblique, transverse abdominis, and erector spinae muscle activity and the spatial parameter. Conclusion: This study demonstrated that a relationship exists between trunk stabilization muscle activation and temporal parameter (i.e., gait velocity, single support phase, double support phase, swing phase, and stance phase) during gait analysis. Therefore, the trunk's stabilizer muscles play an important role in the gait of healthy individuals.
