Atopic dermatitis (AD) is a chronic inflammatory skin disease accompanied by severe itching, mainly before five. The aim of this study is to investigate the effects of 405 nm+850 nm LED light therapy on AD-like symptoms in NC/Nga mice. The mice were randomly placed in the normal (Vehicle), atopic dermatitis-induced (CON), and 405 nm + 850 nm LED light therapy (LED) groups. The LED experimental group conducted 405 nm+850 nm wavelength LED ray therapy for 10 minutes a day for seven days. LED light therapy research confirmed the improvement and improvement of Dermatics score and observed the reduction of epidermal tissue thickness caused by dermatitis. Based on the significant decrease of serum IL-1𝛽 and transdermal moisture loss and serum IgE concentration due to LED light therapy, LED light therapy can help restore normal skin conditions in mice that cause atopic dermatitis. This study showed the anti-atopic effect of infrared light and blue light. Light in mice with atopic dermatitis led to the simultaneous use of circular LEDs with two wavelengths.

The purposes of this study was to determine the effects of limited hyperextension at knee joint using Limited Motion Knee Brace on balance and walking in patients with hemiplegia. The subjects of this study were 20 post-stroke hemiplegic patients admitted. Subjects were randomly assigned to either experimental group (Limited Motion Knee Brace group) or control group (manual restriction group). Both groups received traditional physical therapy intervention. The effects of each therapeutic method were evaluated by measurements of gait ability assesment, Berg balance scale (BBS), 10-meter walk speed (10MWS), Timed Up & Go (TUG) Test. The results of this research were as followings: (1) After treatment, there were significant BBS scores differences in both experimental and control group compared with pre-treatment(p<0.05). (2) After treatment, there were significant TUG test scores differences in both experimental and control group compared with pre-treatment (p<0.05). (3) After treatment, there were significant 10MWS differences in both experimental and control group compared with pre-treatment (p<0.05). (4) There were significant BBS scores differences in third and fourth week between experimental and control group (p<0.05). It was concluded that Limited Motion Knee Brace was effective for improving balance and for reducing fatigue for experimental group. Therefore, further studies are required to investigate the effect of knee orthosis for improving balance and walking in patients with hemiplegia.

This study aims to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and muscle tone, targeting the children with spastic diplegic cerebral palsy. 16 children with spastic diplegic cerebral palsy in IV phase of GMFCS were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, only trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. The trunk muscle strengthening exercise consisted of 2 exercises to strengthen abdominal muscles and back muscles. BPM(Balance Performance Monitor) was used to measure balance performance and MMAS(Modified Modified Ashworth Scale) was used to measure muscle tone. As a result, the changes of sitting balance performance in experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05), the comparison of changes in sitting balance performance in between experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05). Knee flexor muscles and hip adductor muscles in both groups show no significant difference in changes of the muscle tone(p>.05). Therefore, the balance performance in both experimental groups and control groups was improved. However, the experimental group had more significant improvement in balance performance and no change in muscle tone was detected in both groups. Thus, these findings show trunk muscle strengthening exercises are effective in improving the balance performance of sitting posture for the children with spastic diplegic cerebral palsy without changing muscle tone.

The purpose of this study was to examine the effects of a thoracic mobilization exercise using the Kaltenborn on the convergence lung function. The study was conducted on 20 university students in their 20s over a four-week period. The 20 subjects were randomly selective assigned to a Kaltenborn thoracic mobilization exercise group and diaphragm exercise control group. The experimental group performed a Kaltenborn thoracic mobilization exercise for 30 minutes. The control group performed a diaphragmatic breathing exercise for 30 minutes. Each exercise program was performed three times a week for four weeks. When comparing the breathing capacity of the experimental and controls before and after the experiment, the experimental group showed significant changes in TV, IRV. In testing the differences between the experimental and controls in their changes after the experiment, TV, IRV showed a significant change. Based on the results of this study, a thoracic mobilization exercise using the Kaltenborn thoracic mobilization exercise may have positively affected the extrementals lung function. Therefore, if a thoracic mobilization exercise using the Kaltenborn is combined with a respiratory exercise program in the future, it will likely become a more effective treatment technique.

The purpose of the present study was to test hypothesis that, because it uses tri-dimensional sensory pathway which have been showed a higher rate of neural activities than uni- or bi-dimensional's, lab-activity-based instruction is more effective teaching strategy in learning science than verbal-based instruction. In the present study, manipulative teaching strategy that uses visual, somatosensory and auditory information pathway was regarded as a mode of tri-dimensional sensory inputs. In addition, verbal teaching strategy that uses mainly auditory and a little visual information pathway was used as a mode of bi-dimensional sensory inputs. Fifty-six students who failed to successfully solve two proportional reasoning tasks (i.e., pouring water tasks) were sampled for this research from a junior high school. The subjects were randomly divided into a manipulative or a verbal teaching group, and given manipulative or verbal tutoring on the use of proportional reasoning strategies and a test of proportional reasoning during instruction. The results showed that manipulative group's performance on the test of proportional reasoning during instruction showed significantly higher performance than verbal group's (t=2.45, p<0.02). The present study also discussed some educational implications of the results.

In this study, we aimed to investigate the effect of Chinese gooseberry (kiwi)-based products on the improvement of intestinal function and constipation. In this study, 21 participants with no underlying disease and complaining of subjective constipation symptoms were selected. Through a pre-experimental design, the main effects, including the colon stagnation score and colon transit time, were assessed after the consumption of Chinese gooseberry (kiwi)-based products. To evaluate the side effects of this product, a subjective constipation assessment test was performed to analyze the degree of constipation improvement at an individual level. The results for the main effects revealed that the number of constipation groups was statistically significantly decreased, and the colon stagnation score and colon transit time were also reduced. Additionally, the participants' subjective constipation assessment test revealed a significant improvement in both intestinal function and bowel activity before and after the consumption of Chinese gooseberry (kiwi)-based products. Similar to the previously known kelp-, lactobacillus-, and fiber-based products, we showed that Chinese gooseberry (kiwi)-based products exert a significant effect on the improvement of the intestinal function and constipation. Furthermore, the results of this study provide valuable information for the development of healthy food products in the future that can help improve bowel movement. Moreover, Chinese gooseberry (kiwi) used in this study is not a functional food and is easily accessible. However, this study has several limitations as it is based on a pre-experimental design. Therefore, studies on randomized experimental and control groups are needed in the future.

Purpose: The purpose of this study was to evaluate the cleansing effect of recently developed alkaline ionized water, e-WASH, on microorganisms of the denture surface. Materials and methods: Removable partial and complete dentures were randomly assigned to the experimental group of 41 dentures, and the control group of 26. The denture was immersed in the e-WASH solution (experimental group), or tap water (control group) for 5 minutes. The plaque was collected from the denture surface before and after immersion, and smeared on the slide glass. Amount and motility of microorganisms were compared according to the morphology and strain of microorganisms, using the phase contrast microscope. Statistical analysis was accomplished with paired t-test and independent t-test at 95% confidence level (P<.05). Results: 1. The amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were decreased after denture cleansing with the alkaline ionized water, e-WASH (P<.05). But in the control group, only the amount of cocci showed a significant difference (P<.05), but no difference from the others. There were no differences in other analysis. 2. In the experimental group, the amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were smaller and more inactive compared to the control group (P<.05). Conclusion: These results indicated that the alkaline ionized water, e-WASH could effectively reduce the amount and motility of the experimented microorganisms on the denture surface, and that e-WASH could be recommended as an effective denture cleanser.
