Objectives: This study aimed to analyze the correlation between oral function, oral environment, and brain cognitive function in the elderly. Methods: The subjects were 60 users of senior community center and elderly day care center. The survey was conducted from November to December 2018. Subjects were assessed by oral examination and myofunction test. Oral myofunction was measured using $IOPI^R$ and Lip de $Cum^R$. Survey data were analyzed using the statistical programs of PASW Statistics ver. 18.0. Results: Tongue muscle strength and lips muscle strength was higher in males than in females. The tongue and lip strengths were higher in the <81 years old group than the ${\geq}81$ years old group. Functional tooth analysis showed that there was a ${\geq}15$ teeth group ($40.91{\pm}7.36$) and a <15 teeth group ($32.52{\pm}7.14$). Lip muscle strength analysis showed that the ${\geq}15$ teeth group ($10.54{\pm}3.40$) was higher than the <15 teeth group ($8.20{\pm}2.41$, p<0.05). Tongue muscle strength, lumbar muscle strength, and functional tooth number were lower in the elderly subjects with mild cognitive impairment. Cognitive function was significantly correlated with functional tooth number (r=0.386, p<0.001), tongue strength (r=0.478, p<0.001), and lip strength (r=0.281, p<0.05). Tongue strength was significantly correlated with lip strength (r=0.360, p<0.001) and functional tooth number (r=0.633, p<0.001). Lip strength was significantly correlated with functional tooth number (r=0.376, p<0.001). Conclusions: These results showed that age and functional tooth number influenced oral muscle strength and that the number of functional teeth and oral muscle strength were low in the elderly with mild cognitive impairment. Oral myofunction training and oral care program are suggested to improve the quality of life of the elderly.

Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) respiratory muscle strengthening exercise on the pulmonary function, back pain, and disability level of patients with chronic low back pain (CLBP). Methods: There were 24 CLBP patients randomly divided into the experimental group (n = 12) who took part in PNF respiratory muscle strengthening exercise and the control group (n = 12) who performed a mock treatment. Both groups performed their respective interventions for 15 min five times per week for four weeks. The pulmonary function was measured using a portable spirometer. The back pain of the participants was assessed using a visual analogue scale. The Oswestry disability index was conducted to measure disability level. A paired t-test was performed to compare within-group changes before and after the PNF respiratory muscle strengthening exercise. Differences between the experimental and the control groups were analyzed using an independent t-test. For all tests, the level of statistical significance was α = 0.05. Results: The within-group change in pulmonary function was significantly different in the experimental group (p < 0.05), and the levels of back pain and disability were significantly different between the groups (p < 0.05). There was also a significant between-group difference in pulmonary function, back pain, and disability level after intervention (p < 0.05). Conclusion: These results suggest that PNF respiratory muscle strengthening exercise enhances pulmonary function and reduces levels of back pain and disability in patients with CLBP.

Objective: This study was conducted to investigate the effect of high-intensity laser therapy(HILT), transcutaneous electrical nerve stimulation(TENS), and ultrasound(US) treatment on pain, grip strength, and hand function in patients who had undergone carpal tunnel syndrome surgery. Design: A randomized controlled trial. Methods: Thirty patients who had undergone carpal tunnel syndrome surgery were randomly assigned to receive either TENS combined with HILT, US combined with HILT, or only HILT as the control group. Treatments were applied around the surgical site, and pre- and post-treatment changes were evaluated. Pain was assessed using NPRS, hand symptoms using CTS-6 and BCTQ-SSS, grip strength with an electronic dynamometer, and hand function using BCTQ-FSS. Treatments were administered seven times over two weeks. Results: The pain and symptoms were significantly reduced(p<0.05) and grip strength and hand function were significantly increased(p<0.05) after treatment compared to before treatment for all subjects. Pain was significantly reduced(p<0.05) and grip strength was significantly increased(p<0.05) in the TESN+HILT group and US+HILT group compared to the Control group. Hand symptoms were significantly reduced(p<0.05) and hand function significantly increased(p<0.05) in the TENS+HILT group compared to the Control group. Conclusions: TENS combined with HILT was found to be more effective than US combined with HILT in reducing pain and symptoms and improving grip strength and hand function in patients following carpal tunnel syndrome surgery. These findings suggest that these treatment modalities can be beneficially applied in clinical practice.

Purpose: The purpose of this study was to identify the effects of exhalation breathing exercises using expirometer and that of inhalation breathing exercises using incentive spirometry on pulmonary function and complications in elderly patients with upper-abdominal surgery. Methods: The research design was a nonequivalent control group non-synchronized design. Participants were 63 patients who underwent upper-abdominal surgery under general anesthesia (32 in experiment group, 31 in control group). They were recruited at P university hospital from August 1 to November 30, 2015. Effects were evaluated by measuring pulmonary functions (Forced Vital Capacity [FVC], Forced Expiratory Volume in 1 second [FEV1]) and pulmonary complications. Data were analyzed using SPSS/WIN 18.0 program. Results: There was no difference in FVC between the experimental group and the control group, but FEV1 in the experimental group increased significantly compared to the control group by time change (p=.001). Also, there were no pulmonary complications in the experimental group but there were 5 cases (16.1%)(p=.018) in the control group. Conclusion: Findings indicate that exhalation breathing exercises by elderly patients following upper-abdominal surgery is an effective nursing intervention in enhancing pulmonary function and preventing pulmonary complications.

Effect of ischemic preconditioning on left ventricular function after cardiac arrest in isolated rat heart.Ischemic preconditioning reduces infarct size caused by sustained ischemia. However, the effects of preconditioning on post ischemic cardiac function are not well-known. The objective of the present study was to determine whether preconditioning would improve the recovery of left ventricular functions after cardiac arrest in isolated rat heart model.Isolated rat hearts were allowed to equilibrate for 20 minutes and were then subjected to either 5 minutes of global, normothermic transient ischemia [Group 2 and 4] or not [Group 3]. A stabilization period of perfusion lasting 5 minutes after the termination of transient ischemia was followed by a standard global, normothermic 20 minute-ischemia and 35-minute reperfusion challenge [Group 3 and 4]. These following results were odtained.1. The recovery of left ventricular developed pressures showed no significant differences between Group 3 and Group 4 at 50 [P>0.3] and 85 minute [P>0.2].2. Heart rates showed no significant differences throughout all the course of experiment and between groups [P>0.5].3. The recovery of left ventricular maximum dP/dt showed no significant differences between Group 3 and Group 4 at 50 [P>0.1] and 85 minute [P>0.2].4. The recovery of pressure-rate products showed no significant differences between Group3 and Group 4 at 50 [P>0.5] and 85 minute [P>0.1].These results suggest that ischemic preconditioning does not provide significant benefit for the postischemic left ventricular functions in isolated rat hearts.

Purpose : After coronavirus disease 2019 pandemic, many people around the world became aware of respiratory diseases and developed increased interest in health and exercise. As the elderly population grows larger, the prevalence of brain diseases and respiratory conditions increases. This study aimed to investigate the impact of dynamic neuromuscular stabilization (DNS) exercises on pulmonary function and electroencephalogram (EEG) findings in the elderly population. Methods : In this study, we measured the pulmonary function and performed EEG of 30 elderly individuals. The participants were randomly divided into an experimental group (n=15) and a control group (n=15). The experimental group completed a DNS exercise training protocol, while the control group performed simple exercise training. After the exercise, the pulmonary function and EEG testing were repeated, and the amounts of change within and between groups were determined. Results : In terms of pulmonary function, the experimental group's forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) increased significantly after the exercise (p<.05), while the FVC differed significantly between groups (p<.05). In terms of EEG findings, the relative alpha waves significantly decreased in the F3 region (p<.05), while the relative beta waves significantly increased in the F4 region (p<.05). The relative gamma waves increased significantly in the Fp2 and P3 regions (p<.05), while the values in the F3 region differed significantly between groups (p<.05). Conclusion : DNS exercises performed by this elderly population demonstrated significant clinical value by providing fundamental data about both pulmonary function and EEG activity.

In this paper we establish the stability of a Jensen type functional equation, namely f(xy) - f($xy^{-1}$) = 2f(y), on some classes of groups. We prove that any group A can be embedded into some group G such that the Jensen type functional equation is stable on G. We also prove that the Jensen type functional equation is stable on any metabelian group, GL(n, $\mathbb{C}$), SL(n, $\mathbb{C}$), and T(n, $\mathbb{C}$).
