Abstract.[Purpose] The purpose of this study was to investigate the effect of task-oriented training and neurodevelopmental treatment (NDT) on the sitting posture of children with cerebral palsy.[Subjects] The subjects were 10 children with spastic diplegia and cerebral palsy due to premature birth.[Methods] The control group (n=5) received NDT and the experimental group (n=5) received the task oriented approach to improve sitting balance control, 5 times per week for 6 weeks. Sitting posture was assessed the gross motor functional measure (GMFM), and electromyography (EMG) pre and post intervention.[Results] GMFM and right rectus abdominis activities showed no significant differences in either treatment. The activity strength of the left rectus abdominis, right and left erector muscles significantly increased in both groups. With regard to the difference in the GMFM and EMG between the experiment and control groups, there was no difference.[Conclusion] The results of this study suggest that the method of task-oriented training and neurodevelopmental treatment for muscle vitalization both improved the sitting posture of children with cerebral palsy.
[Purpose] The present study investigated what kind of effect smart phone use has on
dynamic postural balance. [Subjects] The study subjects were 30 healthy students in their
20’s who were recruited from a University in Busan, Korea. [Methods] The present
experiment was quasi-experimental research which measured the postural balance (Biodex) of
subjects while they sent text messages via smart phones in the standing position with the
eyes open, and while they used two-way SNS. [Results] There were significant differences
between standing and the dual-task situations. Among dual tasks using smart phones, SNS
using situations showed the highest instability. [Conclusion] The use of smart phones in
less stable conditions such as while walking or in moving vehicles should be
discouraged.
This study attempted to investigate the relationships of black consumer behavior perceived by hair specialists with emotional dissonance, self-esteem and turnover intention. For this, a questionnaire survey was performed against a total of 404 hairdressers from across the country as of 2022. The collected data were analyzed by frequency analysis, factor analysis, correlation analysis and structural equation modeling (SEM), and the results found the followings: First, concerning correlations between black consumer behavior perception factors and emotional dissonance, ‘aberrant behavior’, ‘authoritarian behavior’ and ‘deceitful behavior’ had a positive correlation with ‘acting emotion’ and ‘affective conflict’ with statistical significance. They also revealed a positive relation with turnover intention. However, no statistically significant correlation was found between black consumer and self-esteem. Second, according to hypothesis testing, Hypothesis 1 was supported because hair specialists’ perception of black consumer behavior showed a positive effect on emotional dissonance.
Hypothesis 2 was rejected because hair specialists’ perception of black consumer behavior had no influence on self-esteem. Hypothesis 3 was accepted because hair specialists’ perception of black consumer behavior revealed a positive effect on turnover intention. Hypothesis 4 was rejected because hair specialists’ emotional dissonance had no influence on self-esteem. Lastly, Hypothesis 5 was adopted because hair specialists’ emotional dissonance showed a positive effect on turnover intention. It is anticipated that the above results would suggest a future direction for interactions between hairdressers and consumers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
