To enhance learning efficiency, we implement a hybrid experimental system for electrical and electronic circuits where web-based virtual laboratory system and distant education system are properly integrated. In the first stage, we developed web-based virtual laboratory systems for electrical/electronic circuit experiments, which are composed of three important sessions and their management system: concept learning, virtual experiment, assessment. In the second stage, we have implemented cost-effective distant laboratory systems for practicing electric/electronic circuits, which can be used to eliminate the lack of reality occurred during virtual laboratory session. The proposed virtual/ distant laboratory systems can be used in stand-alone fashion, but to enhance learning efficiency we integrated them and developed a creative hybrid experimental system for electric and electronic circuits.

Background: Emergencies in outpatient clinics are rare. However, potentially catastrophic events can be challenging to manage due to a variety of factors, including limited equipment and staff. The purpose of this quality improvement project was to improve the staff knowledge and familiarity with critical performance elements for emergencies encountered in the setting of a periodontics clinic. Methods: Emergency cognitive aids tailored to the clinic's resources were created for anaphylaxis, airway obstruction, and sublingual hemorrhage. The project pre-post-test repeated measures design evaluated the effectiveness of cognitive aids using a combination of hands-on simulation, written knowledge assessments, and self-efficacy surveys. Training sessions and simulations were provided to the clinic's existing care teams made up of a periodontist and two dental assistants with an anesthetist who was present for simulations involving sedation. Due to the small sample size (N = 14) and non-normal distribution, all metrics were evaluated using non-parametric statistics. Results: Significant improvements were found in knowledge assessment (-2.310, P = 0.021) and self-efficacy (-2.486, P = 0.013) scores when retention after a training session before and after the introduction of cognitive aid was compared. The mean simulation scores and times improved steadily or reached maximum scores during the project progression. Conclusion: Training sessions before and after cognitive aid introduction were effective in improving knowledge, self-efficacy, and simulation performance. Future projects should focus on validating the process for creating contextualized cognitive aids and evaluating the effectiveness of these cognitive aids in larger samples.

The objective of this study was to examine the effectiveness of newly developed program for the recovery and relapse prevention in patients with anxiety disorder. Twenty-four patients with anxiety disorder received Mindfulness-Based Cognitive Therapy (MBCT) session weekly for a period of overall 8 weeks-program. Changes of depression, anxiety, negative and positive automatic thought were compared before and after the program. Depression and anxiety were improved significantly after the MBCT program(Z=-1.9, p=.06, Z=-2.9, p<.001). Conclusions: MBCT may be effective at reducing negative automatic thought and relieving anxiety and depressive symptoms in patients with anxiety disorder. However, large-sample, randomized controlled trials will be needed for generalization.

Objective: Patients with scoliosis complain of various symptoms such as muscle imbalance, dysfunction, back pain, abnormal posture and gait abnormality. The most basic treatment for scoliosis is to observe the progress based on conservative treatment. Therefore, in this case report, the effect of cytoskeletal manual therapy (CMT), a soft tissue mobilization technique, on pain intensity, muscle thickness, and pressure pain threshold (PPT) in a patient with scoliosis was investigated. Design: A case report Methods: A 25-year-old male diagnosed with scoliosis visited the Neuromusculoskeletal Science Laboratory with chronic back pain. In the laboratory, scoliosis was confirmed through the X-ray image used for his diagnosis, and it was confirmed again through Adam's forward bending test. Pain, pressure pain threshold and muscle thickness were measured to compare the immediate effects of CMT applied in the laboratory for 40 minutes. Treatments were visited two weeks after the first visit and outcome measures were assessed after a total of two visits. Results: After receiving CMT up to the second session, the pain intensity decreased by 4 points and the screening angle decreased by 15 degrees. Muscle thickness decreased in all but 10 mm on the dominant side of the thoracic spine. All of the PPTs increased, and the greatest increase was 3.1 lb on the dominant side of the thoracic spine. Conclusions: CMT showed positive improvement in pain during trunk flexion, spinal curvature, muscle imbalance, and pressure pain, which is considered as an ancillary treatment option for scoliosis management.

Background: This report determines the effects of a neurofeedback program on patients with breast cancer through a study of psychogenic factors(distress, depression, anxiety). Design: Randomized controlled trial. Methods: The study selected 28 patients with breast cancer and divided them into two groups: 14 subjects in the neurofeedback program group and 14 subjects in the exercise intervention program group. Both groups conducted one-and-hour training per session five times a week for a total of five weeks. The experimental group performed neurofeedback, and the control group performed a exercise intervention. The distress was measured using the distress management Test. Beck's Depression Inventory was used to measure depression. Beck's Anxiety Inventory was used to measure Anxiety Results: Both the experimental and control groups showed significant differences in distress, depression, and anxiety after the intervention (p<0.05) in the within-group comparisons. It was found that the experimental group showed more significant differences in distress, depression, and anxiety than the control group (p<0.05) when the two groups were compared. Conclusion: The results obtained in this study show that the neurofeedback program had a positive effect on distress, depression, and anxiety of life in patients with breast cancer. The study thereby proposes that the neurofeedback program should be applied as an intervention method for clinical use on patients with breast cancer.
