Objectives : The purpose of this research is to review the efficacy and safety of taping therapy for facial palsy. Methods : Two foreign databases(Pubmed, CNKI) and one domestic database(OASIS) were used to search, and papers retrieved from the starting point of literature provision in each database until June 19, 2023 were included in the study. All studies in which other treatments were performed as a treatment intervention along with taping therapy were included, but cases where taping therapy was a comparative intervention were excluded. Results : 18 studies were selected. 14 studies were two-arm randomized controlled trials(RCT), and 4 studies were case reports. There was improvement in facial palsy in all 4 case reports, and in all 14 RCTs, the treatment effect in the observation group was significantly higher than in the control group. Conclusions : Taping therapy can be an effective and safe treatment method for facial palsy. However, the risk of bias in the selected studies was high, and there were many cases in which multiple interventions other than taping therapy were applied simultaneously. Therefore, well-designed studies with high quality are needed in the future.

Background: This study aimed to investigate the effect of local anesthesia (LA) on postoperative pain and hemostasis after dental rehabilitation under general anesthesia (DRGA) in pediatric patients. Methods: A total of 43 patients, aged 3-7 years and rated ASA I or II, who had a definitely negative rating on Frankel's behavior rating scale, were included in this two-arm, parallel-design, single-blinded, randomized, controlled study. The patients were allocated equally into two main groups receiving both restorative treatments and tooth extractions. Two pain scales and one bleeding scale were used. In Group A, the treatment was done with LA, and in Group B, the treatment was done without LA. Results: The statistical analysis revealed no significant differences in the pain scores between the groups. It also revealed significant differences in the bleeding scores between the groups but no significant differences in the duration of bleeding. Conclusion: Within the limitations of this study, the use of LA in pediatric dental patients undergoing DRGA had no effects on postoperative pain reduction or bleeding duration after teeth extraction. We also observed that the use of LA had an impact on the reduction in the bleeding scores in pediatric dental patients undergoing DRGA.

In the beginning brain waves were used for monkeys to control robot arm with neural activity. In recent years there are research that measured brain waves are used for the control of programs which monitor the progression of dementia or enhance of attention in children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Moreover, low-price devices that can be used as a game control interface have become available. One of the problems associated with control using brain waves is that the mean amplitude, mean wavelength, and mean vibrational frequency of the brain waves differ from individual to individual. This paper attempts to propose a method to normalize measured brain waves using normal distribution and calculate the waveforms that can be used in controlling games. For this, a framework in which brain waves are converted in seven stages has been suggested. In addition, the estimation process in each stage has been described. In an experiment the waveforms of two subjects have been compared using the proposed method in the BCI English word learning program. The level of similarity between two subjects' waveforms has been compared with correlation coefficient. When the proposed method was applied, both meditation and concentration increased by 13% and 8%, respectively. Because the proposed regularization method is converted into a waveform fit for control functions by reducing personal characteristics reflected in the brain waves, it is fitting for application programs such as games.

Purpose : The purpose of this study was to determine the effects of upper extremity volume, pain, and range of motion after participation in thera-band exercises according to the hand grip type in patients with breast cancer with upper extremity edema. We also aimed to determine the most efficient type of grip. Methods : The subjects were 10 female patients diagnosed with stage 2 breast cancer who had stage 2 lymphedema. Randomly, 5 patients each were allocated to the experimental and control groups. For six weeks, the patients in both the experimental and control groups exercised daily. In both groups, manual lymph drainage was applied for 1 hour. Afterward, patients in the experimental group placed their hands in the thera-band ring and exercised with their fingers outstretched. Patients in the control group exercised while holding the thera-band ring with a finger. Both the experimental group and the control group underwent measurements of the circumference of the upper extremity, pain, and range of motion of the shoulder joint at weeks 1, 2, 4, and 6 before and after exercise. Results : The upper arm circumference decreased by more in the experimental group in all weeks than before than that in the control group, and there was a statistically significant difference at 6 weeks. Compared with the difference between pre-exercise and 6 weeks post-exercise, the change in pain significantly decreased in the experimental group and showed a statistically significant difference. The shoulder range of motion increased in extension, external rotation, and internal rotation compared with that in the control group, and there was a statistically significant difference. Although the operating range increased in flexion and abduction, there were no statistically significant differences. Conclusion : In this study, we found that thera-band exercises with an open-hand grip are more efficient than thera-band exercises with a closed-hand grip in edema reduction, pain, and range of motion. In addition, it was found that it was more effective to continue the thera-band exercises with open-hand grip extended for at least 6 weeks rather than for a short time.

Extraoral maxillofacial prostheses are essential for restoring facial structures that are lost as a result of congenital missing, injuries from accidents, surgical treatments of head and neck cancer. Recently, silicone is the most useful material for this purpose and is more advantageous than other maxillofacial prosthetic materials. However, there are some problems for long-term usage of silicone prostheses due to tear and color change. These are major contributing environmental factors to those problems that are such as ultraviolet light, cleansing agents, changes in humidity and successive adhesion and removal. The aim of this study is to evaluate the physical properties and color changes of maxillofacial prosthetic silicone material by those environmental factors using A-2186 silicone material (Factor II, USA) and two pigments, cadmium yellow medium and cosmetic red. Aluminium molds were fabricated according to the ASTM No. D412 & D624 specifications and resulted specimens from molds were fabicated and treated as follows. Control group and experimental I group were fabricated with 0.1% wt. pigment mixing in silicone elastomer and II-1 group, II-2 group of experimental II group were fabricated with 0.2%, 0.3% wt. pigment mixing in silicone elastomer, respectively. Control group was kept in darkroom at room temperature, I-1 group was kept under natural sunlight during 1week, I-2 group was soaked in 20% soap water during 1wk. I-3 group was successively adhered and removed 200 times on inner region of arm using Daro adhesive-33. Experimental II groups were kept in darkroom at room temperature. Instron universal testing machine was used to measure the % elongation, tensile strength, tear strength of control, experimental I, II groups and reflectance spectrophotometer(COLOR EYE-3000, Macbeth, USA) was used to measure the color differences between control group and experimental I group. The results were as follows : 1. When compared with control group, natural weathering group and 20% soap-water soaking group had no significant differences in % elongation(p>0.05). 2. 200 times successive adhesion and removal group, 0.2% wt. pigment group and 0.3% wt. pigment group had significant decreases in % elongation(p<0.05). 3. Natural weathering group, 20% soap-water soaking group and 200 times successive adhesion and removal group had no significant differences in tensile strength (p>0.05). 4. 0.2%, 0.3% wt. pigment groups had significant decreases in tensile strength(p<0.05). 5. Values of all experimental groups were decreased in tear strength. and 200 times successive adhesion and removal group had significant decrease in tear strength(p<0.05). 6. Natural weathering group and 20% soap-water soaking group had significant color differences(${\Delta}E$) and it could be detectable to naked eye(p<0.05). 7. Color differences between control group and 200 times adhesion and removal group were not detectable to the naked eye (${\Delta}E<1.0$).

Objectives : The purpose of this study is to determine the effect of Bee-venom Acupuncture on upper limb spasticity control in stroke patients. Methods : Ten stroke patients with upper limb spasticity were randomly divided into two groups, a Bee-Venom Acupuncture group(group I) and a normal saline group(group II). After 1 week resting phase, this trial was used a cross-over trial. The numbers of Pharmacopuncture treatment were 3 times a week for 3 weeks. Modified Ashworth Scale(MAS), WMFT(Wolf Motor Function Test), The 10-second Test were used for evaluation of spasticity control before experiment, after 1 week, 2 weeks, 3 weeks. Results : Group I showed significant improvement(p<.05) in MAS, WMFT, The 10-second Test. But Group II showed no significant improvement(p<.05) in MAS, WMFT, The 10-second Test. The results showed significant difference in WMFT, The 10-second Test, but no significant difference in MAS between two groups. Conclusions : These results showed that Bee-venom Acupuncture might decrease upper limb spasticity and increase arm motor function in stroke patients. Further studies will be required to examine more cases in the long period for the effect on upper limb in spasticity by Bee-Venom Acupuncture.

Background: Qigong is highly favoured among Asian breast cancer survivors for enhancing health. This study examined the hypothesis that quality of life (QoL) in the Qigong group is better than the placebo (aerobic) or usual care group. Materials and Methods: A total of 197 participants were randomly assigned to either the 8-week Kuala Lumpur Qigong Trial or control groups in 2010-2011. Measurement taken at baseline and post-intervention included QoL, distress and fatigue. Analysis of covariance (ANCOVA) and Kruskal Wallis were used to examine for differences between groups in the measurements. Results: There were 95 consenting participants in this 8week trial. The adherence rates were 63% for Qigong and 65% for the placebo group. The Qigong group showed significant marginal improvement in Quality of life scores compared to placebo (mean difference=7.3 unit; p=0.036), compared to usual care (mean difference=6.7 unit; p=0.048) on Functional Assessment Cancer Therapy-Breast measure. There were no significant changes between the placebo and usual care groups in fatigue or distress at post intervention (8-week). Conclusions: Cancer survivors who participated in the Qigong intervention showed slightly better QOL. Follow up studies are greatly needed to evaluate which subgroups may best benefit from Qigong. With a steep rise of cancer survivors, there is an urgent need to explore and engage more cultural means of physical activity to fight side effects of treatment and for cancer control in developing countries.

Recently, UFRs (Unmanned Flying Robots) have begun to be utilized in various areas for civilian and military applications. Due to this increased utilization, accidents involving UFRsare also increasing. To prevent or monitor accidents caused by UFRs, high-accuracy positioning information is one of the most important technical elements. This paper proposes an efficient UFR monitoring system which provides accurate UFR positioning information with low-cost onboard elements; a small ARM module based on an embedded Linux operating system, a low-cost single frequency GPS receiver with a cheap patch antenna, and a versatile wireless network interface module. The ground monitoring system employs a dual frequency GPS receiver to generate exact UFR coordinates with cm-level accuracy. By processing the UFR measurements based on the Inverse RTK (Real Time Kinematic) method, the ground monitoring system determines the cm-level accurate coordinates of the UFR. The feasibility of the proposed UFR monitoring system was evaluated by three experiments in terms of data loss and accuracy.

The use of a gym ball is becoming more popular for dynamic balance exercises. However, little is known about the effects of the dynamic ball exercises in the elderly. The purpose of this study was to compare balance and functional mobility after dynamic balance exercises using a gym ball to reduce the risk factorfor falls. All of the 15 subjects were women between the ages of 68 and 91 (mean age=79.9 yrs, SD=5.87) at anursing home in Wonju. Seven of fifteen subjects were placed in the experimental group and the others in the control group. Three clinical tests were used to determine the degree of balance and functional mobility before beginning the exercise program, after 4 weeks of gym ball exercise, and after 8 weeks of gym ball exercise. These three tests included Timed Up & Go (TUG), Berg Balance Scale (BBS) and the Functional Independence Measure (FIM). Dynamic ball exercises training for 8 weeks (5 days per week) included side stretching, prone walking, bridging, marching and opposite arm and leg lifting. There were significant differences found before the gym ball exercise program began and after 4 weeks and then 8 weeks in the experimental group (p<.05). Significant differences between the groups were shown for TUG and BBS (p<.05). No significant difference was noted between the groups for FIM. Therefore, gym ball exercises can improve dynamic balance and may be recommended to include in a therapeutic program to help the elderly reduce their risk of a fall.

The purpose of this study was to characterize the putative anxiolytic-like effects of the aqueous extract of the root of Polygala tenuifolia ( AEPT) using an elevated plus maze (EPM) and hole-board apparatus in mice. The AFPT was orally administered at 50, 100, 200 or 400 mg/kg to ICR mice, 1 h before the behavioral evaluation in the EPM respectively. Control mice were treated with an equal volume of saline, and positive control mice with buspirone (2 mg/kg). Single treatments of the AEPT significantly increased the percentage of time spent and arm entries into the open arms of the EPM vedrsus saline controls (P<0.05). Moreover, there were no changes in the locomotor activity and myorelaxant effects in any group compared with the saline controls. In the hole-board test,single treatments of the AEPT (200 and 400 mg/kg) significantly increased the number of headdips versus saline controls (P<0.05). In addition, the anxiolytic-like effects of the AEPT were blocked by WAY 100635(0.3mg/kg, I.p), a5-$HT_{1A}$ receptor antagonist not by flumazenil, a $GABA_{A}$ antagonist. These results indicate that P. tenuifolia is an effective anxiolytic agent, andsuggest that the anxiolytic-like effects of P. tenuifolia is mediated via the serotonergic nervous system.
