This research is to find out which position is more effective on exercise. This study compared paricipants in their twenties on sitting position & standing position doing abdominal breathing of their respiration & abdominal muscle activation for 4 weeks. In sitting position, FEV1 was the biggest after breathing exercise. In standing position, the gap was biggest between the FEV1 & forced expiratory flow before and after the exercise. In standing and supine position, Lt. rectus abdominis before exercise and Rt. rectus abdominis after exercise muscle activities were the biggiest. Both posture exercise of repeated measure of analysis result, before and after the exercise of the rectus abdomonis muscle and external oblique muscle were not difference in both muscle activity(p>.05). Left Musculus obliquus externus abdominis before and after physical exercise, it's showed a meaningful difference(p<0.05). Before and after exercise, saw a meaningful difference the efforts of FEV1/FVC(p<0.05). The left external oblique abdominis muscle showed the most muscle activity in the supine position before/after exercising, the efforts expiratory showed the lowest muscle activity.The results from the repeated measures ANOVA regarding to before/after the volume and muscle activity, it showed significant difference between at the right rectus abdominis muscle(p<.05).

The purpose of study was to compare respiratory function and quadriceps muscle activity in stroke patients by applying inspiratory muscle training combined with whole body vibration. In addition, the purpose of study is to present an exercise method for improving the respiratory function of stroke patients and the function of the lower limb muscles of stroke patients. Totally, 21 patients with Stroke patients were randomly assigned to two groups through clinical sampling. 11 patients who applied whole body vibration combined with respiratory exercise were randomly assigned to Experiment Group I, and 10 patients who applied placebo exercise combined with breathing exercise were randomly assigned to Experiment Group II. And for 5 weeks, 4 days/week, 1 time/day, 4 sets/1 time intervention program was implemented. Before intervention, the respiratory function was measured with a maximum inspiratory pressure meter, the lower extremity muscle activity was measured using the surface EMG, and the balance ability was measured using a bug balance test. And after 5 weeks, the post-test was re-measured and analyzed in the same way as the pre-test. In the comparison of changes within the group of experimental group I, there were significant differences in the activity and balance of the respiratory muscle strength, the biceps femoris, and the anterior tibialis muscle (p<.05). In the comparison of the changes in the experimental group I, there was a significant difference in respiratory strength and balance (p<.05). In the comparison of changes between groups, there was a significant difference in the activity of the biceps femoris and anterior tibialis (p<.01). In the future, research on protocols for respiratory exercise and whole body vibration to improve neuromuscular function is considered to be necessary.

Sleep-disordered breathing (SDB) induces dysfunction of the orofacial muscles, leading to morphologic alteration of the face and dental malalignment. Early diagnosis and treatment of SDB is required in pediatric patients to ensure normal facial growth. Myofunctional therapy (MFT) is a modality for the treatment of SDB and prefabricated appliances can be used. Herein 2 cases of malocclusion with SDB, in which MFT with a prefabricated appliance was used for orthodontic treatment, have been described. SDB was diagnosed based on clinical symptoms taken by interview and home respiratory polygraphy. In both cases, SDB was improved using prefabricated appliance for MFT. However, resolution of crowding depended on the degree of crowding.

This study was conducted to know the respiration rate in different organ of 4 years old ginseng plant on June 14 and in different root conditions of 6 years old on October 1. Respiration rate of each organ was the increasing order of young berry, leaf, peduncle, stem and root at all temperature(15$^{\circ}C$ to 30$^{\circ}C$). Temperature coefficients of respiration rate from 15$^{\circ}C$ to 30$^{\circ}C$ of each organ were 2.39 in young berry, 1.75 in leaf, 1.57 in root, 1.17 in stem and 1.16 in peduncle. There was no difference between respiration rate of large size root (117${\pm}$8.8g) and that of small size (54${\pm}$4.0g) in 6 years old ginseng. Respiration rate was decreased with the decrease in the water content in root, especially in small size root. And respiration rate of red skin root was higher than that of healthy root.

This study was designed to examine the effects of complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle on pulmonary function and cerebral cortex activity in patients with severe chronic obstructive pulmonary disease. After collecting samples from 20 patients with severe chronic obstructive pulmonary disease aged 60 to 80, 10 patients each were randomly placed in an experimental group and a control group. The experimental group conducted complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle, and the control group only conducted complex breathing exercise. As a pretest, pulmonary function and cerebral cortex activity were measured. The intervention program was applied to each group for 30 minutes, once a day, for 4 days a week, for 6 weeks, and the posttest was carried out the same way as the pretest. As a result, both groups showed significant differences in FEV1.0(Forced Expiratory Volume in One Second)(p<.001)(p<.05), and there were significant differences between the groups as well(p<.05). When comparing alpha waves in each domain of cerebral cortex, both of the experimental and control groups showed significant differences in Fp1, Fp2, F3 and F4 domains (p<.01)(p<.05). During the 6-week experiment, complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle improved pulmonary function of patients with severe chronic obstructive pulmonary disease, and in relation to cerebral cortex activity, a positive breathing change was found due to the increase of alpha waves in the forehead domain. Therefore, it is considered that applying neuromuscular electrical stimulation of Quadriceps Femoris muscle to patients with severe chronic obstructive pulmonary disease additionally along with complex breathing exercise will bring a better therapeutic effect.

The effect on strength and endurance training (SET) (2 patients) were compared with those of strength training(ST) (2 patients) in patients with-chronic obstructive pulmonary disease. The result of training was assessed by 4 tests: maximal inspiratory pressure(PImax), sustainable inspiratory pressure (SIP), maximal voluntary ventiiation(MVV) and bronchitis-emphysema symptom checklist(BESC). Measurements were repeated before and after training per week for 6 weeks. The SET group performed inspiratory muscle training, using a inspiratory muscle trainer 30 minutes per day, 6 days per week and performing endurance training-12-minute walking-2 days per week for 6 weeks, whereas the ST-only group trained for 30 minutes daily, 6 days per week using inspiratory muscle trainer. SET was no significant increase in exercise performance, whereas ST produced an increase in SIP and a decrease in BESC. There was significant change in BESC betweet the two groups. A simple at home training program using inspiartory muscle trainer was more effective than that of SET program in improving exercise performance of some patients with COPD.h COPD.

In this paper, we propose a study compared and analyzed the CPR results and muscle fatigue of the three groups. There is a group that counts loudly when compressing the mannequin's chest (Group A), a group that breathes autonomously without counting (Group B), and a group that breathes abdominally without counting (Group C). Twelve people were assigned to each group, and after performing chest compressions for 5 minutes, the results of CPR were analyzed using a program connected to the mannequin, and the muscle fatigue of the performers was analyzed using wireless electromyography. The most efficient method was found to be group B. If we only look at the speed and depth of compression within the normal range, Group C would be more efficient, but Group B showed significantly lower muscle fatigue, and Group A did not reach the normal range in depth of chest compression and muscle fatigue was the highest. Group B was also found to be the most accurate in hand positioning accuracy, and was also found to be the most efficient in maintaining concentration on chest compressions.

영아의 설근부에 발생하는 악성 종양은 매우 드물다. 저자들은 연하곤란과 폐쇄성 수면 무호흡증으로 의뢰된 17개월 남아의 설근부에 발생한 횡문근육종을 경험하였기에 문헌고찰과 함께 보고하는 바이다. 외래에서 실시한 이학적 검사 상 설근부 전체가 돌출되어 있었으며 단단한 종괴가 촉지 되었다. 조직검사와 기관절개술을 시행하였으며 컴퓨터단층촬영, 양전자 방출 단층 촬영 그리고 뼈 스캔과 함께 염색체 분석을 실시하였다. 조직검사 결과 폐포성 횡문근육종이 확인되었으며 전이의 증거는 없었다. 염색체 분석상 폐포성 횡문근육종에 상응하는 PAX7-FKHR 유전자 전좌가 발견되었다. 8 회의 항암화학요법과 방사선 치료 후 촉지되는 설근부의 종괴는 없었으며 환자가 호소하는 증상도 개선되었다. 추적 관찰 시 시행된 자기공명영상 결과 확연한 종괴 크기의 감소를 확인할 수 있었다. 횡문근육종은 매우 드문 악성 종양으로 수술과 함께 항암화학요법, 방사선치료 등 여러 치료 방법이 동원되지만 전이나 재발이 있을 시 예후는 매우 불량하다. 그러므로 영아에서 연하곤란, 호흡 곤란 등의 증상이 있을 시에는 설근부를 포함한 상부호흡소화관을 적극적으로 검사하여야 하며 악성 종양의 가능성을 염두에 두어야 하겠다.
