Background: Many studies regarding task-oriented training have recently demonstrated functional improvement in patients with post-stroke hemiparesis. The task-oriented approach is very diverse, and chronic stroke patients must have access to a sustained systematic treatment program to enhance their walking ability. Objectives: This study aimed to compare the effects of the task-oriented circuit training and treadmill training on walking function and quality of life in patients with chronic stroke. Methods: Fourteen patients with chronic stroke volunteered for this study. The subjects were randomly divided into a task-oriented circuit training group and a treadmill training group with 7 patients in each. Each training regimen was performed for 30 min a day and 3 days a week for 4 weeks. Assessment tools included the Timed Up-and-Go Test (TUGT), 10-m Walk Test, 6-min Walk Test (6MWT), and the Stroke Impact Scale (SIS). Results: The change in results of the TUGT, 6MWT, and SIS measured prior to and following the training regimens appeared to be significantly different between the two groups (p<.05). In addition, after the intervention, significant differences were found for all parameters in the task-oriented circuit training group and for the TUGT, 6MWT, and SIS in the treadmill training group (p<.05). Conclusion: The findings suggest that task-related circuit training and treadmill training may be helpful to improve walking function and quality of life of patients with post-stroke hemiparesis. Additionally, a task-related circuit training program may achieve more favorable outcomes than a treadmill program.

SnO2/n-Si and ITO/n-Si SIS solar cells have been fabricated ty mears of electron-beam deposition. The optimum oxidation and heat-treatment condition for SnO2/n-Si cells and ITO/n-Si cells are 50$0^{\circ}C$-5min., 30$0^{\circ}C$-10min., and 50$0^{\circ}C$-5min., 30$0^{\circ}C$-20min. respectively. The open-circuit Voltage(Voc), short-circuit current density(Jsc), fill factor(FF), and efficiency (η) under AMI(100mW/$\textrm{cm}^2$) illumination were 0.4V, 34mA/$\textrm{cm}^2$, 0.44, and 6.0%(active area efficiency, 6.9%) for SnO2/n-Si solar cells, and 0.44V, 36mA/$\textrm{cm}^2$, 0.53, and 8.45%(active area efficiency, 9.71%) for ITO/n-Si solar calls.

The overlaid panels are important materials in interior and construction with added surface layers (PVC films, decorative paper, decorative veneer). Generally, the adhesive for decorative veneer to wood-based panel is urea-formaldehyde (UF) adhesive which cause the emission of formaldehyde during not only the manufacturing process, but also service life. In this study, environment-friendly SIS-based hotmelt pressure-sensitive adhesive (PSA) was evaluated as a adhesive for bonding a decorative veneer. The various SIS-based hotmelt PSA was blended as a function of diblock content, softening point of tackifier, tackifier content, and applied to bonding the decorative veneer.

Objectives : This study was evaluated to elucidate the inhibitory potential of Bodusan (BDS) and its components, Strychnos ignatii semen (SIS) and Glycyrrhizae Radix (GR), on human aortic smooth muscle cells (HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by $TNF-{\alpha}$ treatment. Methods : Cytotoxic activity of BDS and its components on HASMC was using 5-(3-caroboxymeth- oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Effect of BDS, SIS and GR on $TNF-{\alpha}-induced$ HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results : The matrigel migration assay showed that BDS effectively inhibited the $TNF-{\alpha}-induced$ migration of HASMC. Moreover, BDS significantly inhibited MMP-9 activity. Our present study demonstrates that BDS and its components inhibits $TNF-{\alpha}-induced$ HASMC migration and MMP-9 activity. The inhibitory effect of BDS extract is more potent than that of its component herb extracts. Conclusions : These results provide evidence that BDS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.

In this study a new SIS evaluation method based on the reliability analysis has been developed. It evaluates the Safety Integrity Level (SIL) using the Fault Tree Analysis (FTA), and when the SIL falls short of the systems target level, through the reliability analysis and system retrofit, this method will satisfy the aimed SIL. A hazard evaluation was carried out on the 415V Diesel BUS to verify the SIL evaluation method based on the reliability analysis. The availability of the original 415V Diesel BUS was $99.40\%$, which comes under the category of SIL 2. After exchanging the diesel generator and the isolator switch using the developed evaluation method, the availability rose to $99.94\%$, SIL 3. By applying the method presented in this study, not only will it reduce the maintenance cost due to the prevention of accidents and reduction of loss, but also maximize the reliability of the system.

Objectives: To develop and investigate the effectiveness of an integrative counseling intervention for enhancing social intelligence and reducing bullying behaviors among lower secondary school students in Bangkok, Thailand. Methods: An interventional mixed-method design was employed in 2 phases. Phase 1 involved the development of a qualitative method-based integrative counseling program from key informants using the eclecticism technique. In phase 2, a randomized controlled trial with a wait-list control was conducted and qualitative research was performed with students who demonstrated bullying behaviors. Demographic data, Social Intelligence Scale (SIS) scores, and Bullying-Behavior Scale (BBS) scores were collected at baseline. Changes in SIS scores and qualitative findings obtained from in-depth interviews were examined after counseling ended, and BBS scores were collected again 1 month later. Results: The developed social intelligence counseling program included eight 1-hour weekly sessions consisting of 3 components: (1) social awareness, (2) social information processing, and (3) social skills. After receiving this intervention, scores for the SIS overall (p<0.001) and all of its components (p<0.05) were significantly enhanced in the experimental group compared to the control group. Moreover, the mean BBS scores in the experimental group significantly decreased 1 month after counseling (p=0.001). With regard to the qualitative research results, the experimental students demonstrated improvements in all components of social intelligence. Conclusions: The results indicated that a preventive counseling program may enhance social intelligence, decrease bullying behaviors among lower secondary school students, and prevent further incidents of school violence. However, further studies in various population subgroups should also be performed.

To evaluate the effectiveness of acupuncture treatment for shoulder impingement syndrome (SIS) a literature review was conducted of randomized controlled trials (RCTs) where acupuncture was used as an intervention for patients diagnosed with SIS. Relevant clinical studies (N = 181) were retrieved from several databases based on the inclusion/exclusion criteria, and the interventions and results were analyzed. Six RCTs were selected to review based on the inclusion and exclusion criteria. In all 6 studies, the acupuncture treatment group showed significant positive changes in indicators evaluating pain, disability, and quality of life. A significant decrease in the evaluation indicators (Shoulder Pain and Disability Index, numeric rating scale, Visual Analogue Scale, Constant Murley Shoulder Assessment Score, patient's global assessment, and doctor's global assessment) and a significant increase in the questionnaire scores (UCLA, AL-score, EuroQol 5 Dimension Self-Report Questionnaire, and disabilities of the arm, shoulder, and hand) were observed. In addition, 1 study showed similar improvements in pain and quality of life measures in the acupuncture group and corticosteroid injection group. No major side effects were reported. Acupuncture may be an effective and safe treatment for SIS however, further RCTs are required.
