Constipation is the most common digestive disorder, and it occurs frequently in the early stages and affects the prognosis on rehabilitation stage in the patients with brain injury. The purpose of this study is to evaluate the bowel habits of brain-injured patients undergoing enteral nutrition immediately after admission to rehabilitation and transmission, and to investigate the effects of abdominal massage and lower extremity exercise. The study design is a quasi-experimental study to investigate the effect of a bowel care intervention (abdominal massage and lower extremity exercise) applicable to patients with brain lesions. As a result of the study, the number of bowel movements was significantly higher in the intervention group (p=.030), and the use of suppositories in the control group was statistically significantly higher than that in the intervention group (p=.004). The time of constipation relief was 1.73 days for the experimental group and 4.61 days for the control group, indicating that there was a difference in the time of constipation relief between the two groups (p<.001). Abdominal massage and lower extremity exercise were effective as nursing interventions to relieve constipation and prevent constipation in patients with brain injury from the early stage of rehabilitation.

This paper presents a study on acoustic characteristics and sound generation mechanism of Cryptotympana atratas' songs which cause noise problems in summer days. The waveforms & FFT of Cryptotympana atratas' songs in nature were analyzed, and the actions of tymbals were visualized by the high speed camera. In order to know resonance frequency of the abdominal cavity of male Cryptotympana atrata, the sine sweep test was done. It was observed from the experimental results that Cryptotympana atrata's two tymbals act asymmetrically with respect to time & shape, and make a variety of frequencies every time it vibrates. It was also shown that Cryptotympana atratas' have a structure that cause resonances sounds only in a $7{\sim}7.5 kHz$ bandwidth.

The Many patients who have lumbar instability(LI) could make a different trunk movement pattern by reduction of their respiratory function and altered breathing pattern. This study was conducted to investigate the change in the thoracoabdominal usage rate(TAUR) on three circumference lines(axillary, xiphoid junction, 10th rib) during the resting and forced breathing (RB and FB) after respiratory pattern correction(RPC) exercises in patients with LI. 15 patients in the experimental group performed RPC exercises, and 15 patients in the control group conducted lumbar stabilization exercises. Before the intervention, both groups had a significant difference in the usage rate among the three thoracoabdominal lines during the RB and FB(p<.05). After the intervention, the experimental group was seen no significant difference in the usage rate among the three lines during the RB(p>.05) and exhibited significant differences in the usage rate between the two thoracoabdominal lines during the FB(p<.05). The RPC exercises might improve the trunk movement patterns by restoring the respiratory patterns. We suggest that the RPC can apply in the re-education and reinforcement process at the reha-program for LI patients.

본 논문은 만성폐쇄성 폐 질환이 흡연, 대기오염으로 많은 질환자가 발생하여 재활운동을 필요로 하는 추세이다. 현재 측정 도구와 재활운동 도구가 분리되어 질환 진단은 한정된 시설을 이용해야만 하고 재활운동 또한 상시 진행할 수 없어 질환을 확인하기 어려운 실정이다. 이에 평상시 착용하는 이너형태에 재활운동 의류를 개발하여 올바른 호흡을 돕는 근육군이 동원하여 복식호흡을 유도하고 흉식호흡 시 웨어러블기기를 통해 인지하게 돕는다. 이 결과 일상 속 지속 가능한 재활운동을 바탕으로 가슴 벽의 호흡근육 활동을 감소시키고 복부 근육군을 개선하는 것으로 폐 기능을 증진시킬수 있는 언더웨어 개발을 제안하고자 한다.

복부의 자기공명영상(Magnetic resonance imaging； MRI)은 주로 간 질환의 검사에서 다른 영상검사로 해결되지 않은 궁금점을 풀기 위한 보조적인 검사로 주로 사용하였으나, 최근 들어서는 병변의 발견 및 감별진단에 직접적인 검사로도 자주 이용하고 있으며, 담췌관 질환이나 위장관 검사 등에도 적용범위가 넓어지고 있다. 이는 그간의 하드웨어 및 소프트웨어상의 발달로 인해, 위장관 연동운동이나 호흡에 따른 인공물을 억제하면서도 해부학적인 세부구조는 자세하게 나타낼 수 있는 우수한 영상을 얻을 수 있음으로써 가능하게 되었다. 고속영상은 영상의 질을 우수하게 할 뿐 아니라, 검사시간을 단축시켜서 더 많은 환자를 검사할 수 있게 하고, 한자가 검사에 더 잘 적응할 수 있게 하여준다. 단발(single-shot)기법의 고속 T2강조영상은 담췌관이나 위장관등 그간 MRI를 적용하기 어려웠던 부위에 대한 검사가 가능하게 하였으며, 고속의 3차원 T1강조 펄스대열(pulse sequence)은 단면에 따른 오기록(misregistration)이나 운동인공물이 적으면서도, 향상된 다평면적인 영상구성을 얻을 수 있게 하였다. ［l］. 본 강좌에서는 최근 수년간 복부 MRI의 응용을 증가할 수 있게 한 영상장치 및 펄스대열의 발전과 최근 국내에 시판이 허용되어 사용이 증가되고 있는 새로운 간자기공명조영제에 관해서 살펴보고자 한다.

Overweight and abdominal obesity caused by sedentary lifestyle may induce deconditioned and atrophied extensor musculature of the lumbar spine and be a potential risk factor for low back pain (LBP). Therefore, this study was conducted to evaluate the validity of high intensity circuit training (HICT) on weight loss and subsequent alleviation of spine curvature (SC) and visual analog scale (VAS) among middle aged men with abdominal obesity. The training program (1 exercise session for 30 minutes, three times a week for 12 weeks) consisted of 12 different functional exercises based on core strengthening multiple joint circuit training. Portions of the obesity index related to body composition were positively changed, which improved the angles of thoracic kyposis and lumbar lordosis, which appeared to effectively reduce lower back pain. Taken together, HICT specifically designed for LBP effectively decreased obesity related body composition and was superior to other treatments for decreasing aggravation of the spine curvature and LBP caused by abdominal obesity; however, weight loss should be the primary treatment target for LBP patients.

Background: More than 70% of morbidity and mortality of diabetes mellitus is due to macrovascular complications. These complications may be associated with defect of endothelium-dependent vascular relaxation. There have been suggestions that this defect might be due to direct toxicities of oxygen-free radical. So in this study ascorbic acid was used as a dietary supplement in streptozotocin induced diabetic rats to correct this defect. Material and Method: Sixty male Sprague-Dawley rats were used in this study. They were divided into control and experimental groups. Streptozotocin was injected to the 33 rats of experimental group and then divided into two the other receiving subgroups; one receiving ascorbic acid supplement(1 g/l in drinking water); and nosupplements. At 6, 9 and 12 weeks, abdominal aortic rings were obtained to make tissue preparations for evaluation of vascular smooth muscle contractility. Result: While control group showed good response to acetylcholine induced relaxation, diabetic group showed decreased relaxation regardless of ascorbic acid supplement at the experiments 6 weeks after streptozotocin treatment. This abnormal endothelium-dependent vascular relaxation was markedly reversed at 9 and 12 weeks into the diabetic group with ascorbic acid supplement. There were no differences in sodium nitroprusside induced relaxation responses between control and experimental groups; also, norepinephrine induced contractile responses did not show any remarkable effects. Conclusion: These results strongly suggest that the endothelial cells have defects in diabetic rats. Dietary supplement of ascorbic acid can reverse the defects of diabetic endothelial cells through its antioxidant effects and it may further protect against vascular disease in diabetic patients.

The purpose of this study was to investigate the effects of 8-week schroth 3-dimensional exercise and ball-sling complex exercise treatment on cobb's angle, abdominal muscle endurance, flexibility and balance in adolescents with idiopathic scoliosis. Thirty subjects with scoliosis were random assignment into one of two experimental groups, either schroth treatment(n=15) or ball-sling complex exercise treatment(n=15). Exercise program was to perform for 8-week and 90min and 3 times per week. The results of this study were as follows; First, cobb's angle was significantly decreased after 8-weeks in schroth treatment(p<.001). And also abdominal muscle endurance(p<.05), flexibility(p<.001) and balance(p<.001) were significantly improve in pre vs. post treatment. Second, the ratio of cobb's angle change was significantly higher in schroth treatment compared to ball-sling complex exercise treatment following 8-weeks(p<.05). These results suggest that although both the schroth treatment and bal-sling complex exercise treatment in adolescents with idiopathic scoliosis can improve on cobb's angle, abdominal muscle endurance, flexibility and balance, but schroth treatment was better than ball-sling complex exercise treatment improving effect of cobb's angle. Therefore, we consider that schroth treatment has more effect of prevention and therapy in idiopathic scoliosis in adolescents.

Background : Cardiopulmonary exercise test is a useful test for the evaluation of the cardiovascular and respiratory systems. Obese subjects have an increased resting metabolic rate ($VO_2$) compared to non~obese subjects and the increase is more marked during dynamic exercise, which results in the limitation of maximal exercise in obese subjects. In this study, the influence of the obesity and fat distribution on the maximal exercise capacity were evaluated. Methods : Maximal exercise capacity was represented by maximam maximum oxygen uptake and $VO_2$ max in the cardiopulmonary test. Obesity, total fat content and abdomina1 obesity(waist to hip ratio, WHR) were measured by bioelectrical impedence method. Total of 42 volunteers (male 22, fema1e 20) were evaluated. Results : 1) Weight to height ratio (mean$\pm$SD) was 110$\pm$14.9% in men and 100$\pm$11.1% in women. 2) Fat ratio (mean$\pm$SD) was 23.3$\pm$5.2% in men and 27.55$\pm$3.9% in woman. 3) Waist to hip ratio (mean$\pm$SD) was 0.85$\pm$0.04 in men and 0.8$\pm$0.03 in woman. 4) In men, $VO_2$ max/min/Kg was negatively correlated with obesity, fat ratio, and abdominal fat distribution. 5) In woman, $VO_2$ max/Kg was negatively correlated with obesity and fat ratio, but did not show significant relationship with abdominal fat distribution. Conclusion : Obesity was a limiting factor for maximal exercise in both men and women. Abdominal obesity was a limiting factor for maximal exercise in men but its implication to women needs further evaluation.
