The present study was to test if breathing training in melodic intonation therapy (MIT) ameliorated the articulation intelligibility of Broca's aphasics or not. The experimental group did breathing training (2 stages) that preceded the MIT. In order to evaluate the efficacy of the MIT intervention, the VOT (Voice Onset Time), the TD (Total Delay), the voice sound intensity and the expiratory volume of the subjects, closely associated with articulation intelligibility were measured before and after the intervention. It was shown that, in the experimental group after the MIT intervention, the VOT and TD were increased on bilabial/p/, alveolar consonant /t/, and soft palatal /k/(p < 0.05), but no significant differences were found on affricate /c/ and fricative /s/(p > 0.05). In the control group, no significant increases in the VOT and TD were observed on all articulation points(p > 0.05). The voice sound intensity which influences the verbal articulation increased in the experimental group after the intervention(p < 0.05), whereas no significant changes were observed in the control group. In conclusion, the breathing training in the MIT was found to result in improving the articulation intelligibility of Broca's aphasiacs.

Purpose: Symptoms of idiopathic Parkinson's disease (PD) include tremors, bradykinesia, and rigidity. The purpose was to explore the effects of breathing, meditation and qigong on the improving of insight, behavior, mood discomfort, depression, anxiety, and olfactory dysfunction, which are PD non-motor symptoms. Methods: Three stages of An's-4444 healing breathing, An's Gwanjeong healing meditation, and healing qigong performed 12 times for 80 minutes at a time in subjects with PD (11 patients), and pre- and post-measurements compared and evaluated. Results: The Integrated Parkinson's Rating Scale (UPDRSI) for mood discomfort after 12 healings was 69%. The Depression Scale (61%) for HAMD, and 64% for Anxiety (HAMA)), and the smell identification test (TSI) for a trial for olfactory dysfunction, improved to 82%, respectively. However, the numerical values after one month after 12 healing were almost same in all four scales. This means that the healing effect maintained until after one month. Conclusions: An's healing breathing, meditation and qigong therapy significantly improved insight, behavior, and mood discomfort, and non-motor symptoms such as depression, anxiety, and olfactory dysfunction. These results suggest that An's breathing, meditation and qigong therapy are valuable as a primary therapy to improve and heal non-motor symptoms in Parkinson's disease patients. Further research in biomedical science is needed.

Purpose : People who have suffered from COVID-19 suffer from decreased pulmonary function and various side effects. This study aims to present three respiratory exercise intervention methods to improve pulmonary function in COVID-19 survivors. Therefore, the purpose of this study will investigate the effects of breathing exercise interventions (aerobic exercise, diaphragm breathe exercise, and inspiratory muscle training on resistance) on pulmonary function in COVID-19 survivors. Methods : The subjects who participated in this study were 35 male and female college students confirmed with COVID-19. All subjects were randomly assigned to A, D, and I groups according to breathing exercise intervention method. Groups A, D, and I each performed aerobic exercise, diaphragm breathing exercise, and inspiratory muscle training on resistance, 3 times a week for 6 weeks. Pulmonary function was measured using a spirometer, and FVC (forced vital capacity), FEV₁ (forced expiratory volume in one second), FEV₁/FVC % (forced expiratory volume in one second / forced vital capacity ratio), and PEF (peak expiratory flow) were measured at 0, 3, and 6 weeks. Data analysis was compared by repeated measures analysis of variance, and post hoc tests for time were compared and analyzed using paired t-tests. Results : In the results of this study, FVC values showed statistically significant improvement in all groups. FEV₁ values also showed statistically significant improvement in all groups. And the FEV₁/FVC % value also showed statistically significant improvement in all groups. And the PEF values also showed statistically significant improvement in all groups. Conclusion : The results of this study reported that aerobic exercise, diaphragm breathing exercise, and resistance inspiratory muscle training were all effective in improving pulmonary function in COVID-19 survivors. Therefore, application of the three breathing exercise intervention methods presented in this study will help improve pulmonary function in COVID-19 survivors.

Purpose: The purpose of this study was to describe the influence of respiration on the segmental motion of the lumbar spine in the lying position. Methods: Twelve healthy females without a history of low back pain participated. Lumbosacral lordosis, intervertebral body angles, intervertebral body displacements, and anterior heights of the intervertebral disc of the lumbar spine were measured at inspiration, expiration and forced expiration in the supine and prone positions via fluoroscopy. Results: The results of lumbar kinematic analysis in the supine position according to respiration pattern were as follows. The L4/5 intervertebral body angle was significantly higher at forced expiration than at expiration (p<0.05). The L3/4 anterior height of the intervertebral disc was significantly higher at expiration than at forced inspiration and the L5/S1 anterior height of the intervertebral disc was significantly higher at inspiration than at forced expiration (p<0.05). There were no significant differences in the intervertebral body displacements and lumbosacral lordosis in the supine position (p>0.05). The results of lumbar kinematic analysis in the prone position according to respiration pattern were as follows. The L5/S1 anterior height of the intervertebral disc was significantly higher at inspiration than at forced expiration (p<0.05). However, there was no significant difference in the intervertebral body angle, the intervertebral body displacements, and the lumbosacral lordosis (p>0.05). Conclusion: These findings suggested that respiration can affect the intervertebral body angle and anterior height of the intervertebral disc in some segments. The results from this study serve as a step in the development of guidelines for lumbar kinematic analysis for lumbar breathing training.

Purpose: The aim of this study is to investigate geometrical and volumetrical changes of liver due to breathing and its impact to NTCP. In order to attain better treatment results it should be considered deliberately during planning session. Mehtods and Materials : Seven patients were examined in this study who have done TACE for accurate tumor margin drawing. After contrast media injection, C-T scan data were obtained in supine position during breathing free, inhalation and exhalation, respectively. For all patients C-T scan were done with same scanning parameters- 5 mm index, 5 mm thickness and pitch 1. Based on C-T data we have measured differences of each variables between breathing status such as changes of total and remained liver volumes, GTV, beam path length and superior to inferior shift. NTCP were calculated using Lyman's effective volume DVH reduction scheme and for this NTCP calculation, the V50 was computed from DVH and each m, n value were referred from Burmans data. Results : The measured total tilter volume and the remained liver volume changed between inspiration and expiration about $1.2-7.7\%(mean+2.7\%)$ and $2.5-13.23\%(mean=5.8\%)$ respectively, and these results were statistically significant(p>0.1). The GTV difference in each patient varied widely from $1.17\%\;to\;30.69\%$, but this result was not statistically significant. Depending on the breathing status, the beam path length was changed from 0.5 cm to 1.1 cm with the average of 0.7 cm, and it was statistically significant(p=0.006). The measured superior to inferior shifts were ranged from 0.5 cm to 3.74 cm. The NTCPs were changed relatively small in each patient, but the variation was large between the patients. The mean NTCP difference was $10.5\%$, with the variation ranged from $7\%\;to\;23.5\%$. Conclusion : Variations of liver volume and of beam path length were changed significantly depending on the breathing statues and the range of variation itself was very different between the patients. Since this variance could seriously affect the clinical outcomes of radiation treatments, the breathing of patients need to be accounted when a final treatment planning is derided.

The data collected to date indicate that sleep-related breathing disorders, including sleep-disordered breathing(sleep apnea) and underlying respiratory system diseases, are one of the important risk factors for cardiovascular dysfunction. Sleep-disordered breathing(sleep apnea) is now recognized as one of the leading causes of systemic hypertension, cardiac arrhythmias, coronary heart disease, pulmonary hypertension, right heart failure, and stroke. Sleep may exert a profound effect on breathing in patients with underlying respiratory system disease including bronchopumonary diseases, chest wall abnormalities, central alveolar hypoventilation syndromes or respiratory neuromuscular disorders. Chronic hypoxia and hypercapnia in these patients may accelerate the development of long term cardiovascular complications such as cardiac arrhythmias, pulmonary hypertension, and right heart failure(cor pulmonale). Several recent studies reported that sleep-related breathing disorders are associated with long-term cardiovascular morbidity and mortality. Careful assessment of respiratory and cardiovascular function in these patients is critical. Aggressive and highly effective treatment of sleep-related breathing disorders using tracheostomy, mechanical ventilation, nasal continuous positive airway pressure therapy(nCPAP), intercurrent oxygen therapy or other interventions can reduce the prevalence of cardiovascular dysfunction and the long-term mortality.

Objectives : The purpose of this study is to analyze an effect of medical Qigong therapy using Dong Chu Chim (DCC) which was invented by "Dongchu Han Medicine Institute", by measuring HRV. We compared effects of DCC with non-treatment, filiform acupuncture and filiform acupuncture with natural abdominal breathing. Methods : 1. The authors stimulated Nogung (PC8) of 26 normal adults by using DCC or filiform acupuncture in turn. 2. The natural abdominal breathing has been carried comfortably with consciousness in the lower abdomen. 3. HRV was measured for 5 minutes, three times (pre-treatment, during-treatment and post-treatment). Results and Conclusions : From this study, it seems that the stimulus of DCC, filiform acupuncture, filiform acupuncture with natural abdominal breathing can all affect the autonomic nervous system and control the balance of that. But there were not significant differences between these stimulus groups and the non-treatment group. Therefore, we suggest additional studies about the effect of DCC in the future.

Purpose : This study aims to investigate the rating of perceived exertion (RPE) and muscle activity of the inspiratory primary and accessory muscle during breathing exercise with different air hole diameters of the inspiratory muscle trainer (IMT). Methods : The Borg's scale and surface electromyography (EMG) was used to collect data of the RPE and muscle activity of the inspiratory primary the external intercostal (EI) and diaphragm (DIA) and accessory muscles anterior scalene (AS), sternocleidomastoid (SCM), pectoralis major (PM), and upper trapezius (UT) muscles during breathing exercise with different air hole diameters (6 mm, 4 mm, and 2 mm) of the IMT in healthy young male subjects. Results : The RPE and muscle activities of the AS, SCM, and UT are increased significantly in accordance to the decreasing diameter of air hole of air tip in IMT. However, there are no differences in the muscle activities of the PM, EI, and DIA based on differences of diameters of air hole of air tip in IMT. Conclusion : The smaller the diametr of IMT air-hole, RPE and muscle activities of AS, SCM and UT were increased. Therefore, further study would be necessary to investigate the proper intensity and relaxation posture for the exercise protocol to strengthen the inspiratory primary muscles.
