Objective: This study aims to analyze the factors that affect the ability to maintain dynamic sitting balance (DSB), biomechanical characteristics, and physical characteristics in spinal cord injuries (SCI) patients. Background: Virtual ski training systems, ski equipment, and training protocols for disabled skiers are being studied to spread awareness. However, few studies have been reported on the sitting balance ability associated with chair mono skiing. Method: A dynamic sitting balance border system was built to investigate the ability to maintain dynamic sitting balance in SCI patients. Trunk muscle activity was evaluated by electromyogram while conducting dynamic sitting balance tests. The trunk muscle strength was tested with a portable handheld dynamometer. Physical activity scores were measured with the physical activity recall assessment. Results: There were high levels of correlation between the ability to maintain DSB and trunk flexor strength, extensor strength, rotator strength, and physical activity score. However, height, weight, and injury level in SCI patients were not correlated with the ability to maintain DSB. Additionally, strong negative correlations were found between muscle activities of the external oblique and lumbar erector spinae muscles and the ability to perform the backward tilt test. Trunk extensor muscle activity during the ball lifting test was significantly higher than in other tests. Conclusion: The results indicate that improving trunk muscle strength and physical activity can increase the ability to maintain DSB. Application: The findings of a close relationship between trunk strength, physical activity, and the ability to maintain DSB need to be reflected in the chair mono ski training program.

The purpose of this study was to identify the effects of cervical alignment, pain, and physique to apply proprioceptive neuromuscular facilitation(PNF) techniques in patients with forward head posture (FHP). The subjects of this study were 24 patients diagnosed with FHP. They were randomly divided into two groups: a PNF group(n=12) and a control group(n=12). The intervention was performed a total of 24 times, 30 min a day, six times a week for four weeks. Data on cervical alignment(forward head displacement, FHD), pain(visual analog scale, VAS), and physique(height, weight, and body mass index) were obtained pre- and post-intervention. Two-way repeated measures ANOVA was used to compare the groups and time. For FHD, the VAS, and physique(height and BMI), there was an interaction effect for the groups and time(p<.001, BMI: p<.05) and main effects for time(p<.001, BMI: p<.05). For weight, there were main effects of time(p<.01). For FHD(p<.01) and the VAS(p<.05), there were main effects for the groups. In the PNF group, there were significant improvements in FHD, VAS, and physique. In the control group, there was a significant increase in FHD. The results of this study indicated that PNF intervention using scapular and upper extremity patterns effective in FHP positively. The use of a therapeutic intervention on physique changes may also be effective in improving poor posture and help to better patients' quality of life.

For the continuous information security governance, we have to focus on not just technical aspects like access control and DRM, but informal level management like information security(IS) behavior, culture, and personal value. But there are few informal level studies, while many formal level studies of IS governance or technical means. This study is an empirical test that how IS culture, normal beliefs, personal behavior and value affect employee's deviant behavior. And we define a lack of an awareness of value and importance on IS regulations in organizations as "Information Security Anomie" with the concept of anomie, a viewpoint on social organization.

The purpose of this study was to analyze the association among high school students' self-efficacy, self-resilience, and oral health promotion lifestyle, identify relevant factors, and provide basic data for oral health promotion programs. The subjects of this study were 287 students, research tool was the structured, anonymous, self-administrated questionnaire. The data were analyzed by SPSSWIN 18.0, Pearson correlation and Hierarchial multiple regression et al. Significant positive correlation was found between self-efficacy and self-resilience and between self-efficacy and oral health promotion lifestyle and positive correlation was also found between self-resilience and oral health promotion lifestyle. Mother's education, past oral health behavior, self-efficacy, and self-resilience affected oral health promotion lifestyle, with the explanatory power of 32.3%. Since self-efficacy and self-resilience are correlated with oral health promotion lifestyle, it is necessary to develop a plan for activating oral health education with the objective of improving the combination of these factors.

Purpose: The purpose of this study is to evaluate the work environment and job satisfaction of hospital workers and to assess their effects on quality of services under the national long-term care hospital evaluation (hereafter, national evaluation), which has implemented since 2008. Methods: A self-administered survey was conducted on 178 hospital workers' at 18 hospitals in Chungcheong province, Korea. Survey questionnaires include questions about respondent' awareness of the national evaluation and any change in work environment and job satisfaction under the national evaluation. We used a path analysis to assess the effects of work environment and job satisfaction on quality of services. Results: Results showed that the effects of the national evaluation on work environment and job satisfaction were positive, which, in turn, leads to better quality of services. Improvements in the work environment under the national evaluation have resulted in increased job satisfaction. High scores for job satisfaction showed a significant association with the quality of services provided in long-term care hospitals. In addition, the national evaluation itself had a positive effect on improving quality of services. Conclusions: In order to facilitate quality improvement activities under the national evaluation, it is suggested that workers be provided with education and training. Continuous efforts to improve work environment and to enhance job satisfaction would lead to provision of better quality of services in long-term care hospitals.

Due to the prevalence of various mobile devices and wireless broadband networks, there has been a significant increase in interest and demand for multimedia streaming services. Moreover, the user can service the participatory video broadcasting service in the mobile device and it can be used to deliver the real-time news and more variety information in the user side. Live multimedia service of user participation should consider not only the video quality but also the delay bounds and continuity of video playback for improving the user perceived QoS (Quality of Service) of streaming service. In this paper, we propose an adaptive rate control scheme, called DeBuG (Delay Bounds Guaranteed), to guarantee the delay bounds and continuity of video playback for the real-time streaming in mobile devices. In order to provide those, the proposed scheme has a quality adaptation function based on the transmission buffer status and network status awareness. It also has a selective frame dropper, which is based on the media priority, before the transmission video frames. The simulation results demonstrate the effectiveness of our proposed scheme.
