PURPOSE: The aim of this study was to evaluate activation of accessory respiratory muscles using electromyography during chest expansion upper extremity flexion, abduction, and external rotation exercises with an elastic band in children with cerebral palsy. METHODS: The subjects were 10 children with cerebral palsy. The inclusion criterion for participation was a Gross Motor Function Classification System level of I to III. The subjects were instructed to perform upper extremity flexion, abduction, and external rotation exercises with inspiration, and extension, adduction, and internal rotation exercises with expiration while seated on a chair without a backrest. PM (Pectoralis major), SCM (sternocleidomastoid), RA (rectus abdominis), and EO (external oblique) muscle activities were measured using electromyography. RESULTS: All tested muscles showed a statistically significant increase in activity after elastic band exercise. There were significant differences in PM, SCM, RA, and EO results after chest expansion exercise using elastic band. SCM showed the largest increase in activity after use of elastic bands, at $52.37{\pm}45.88$%, followed by the RA ($50.56{\pm}79.31$), EO ($35.42{\pm}35.45$), and PM ($31.72{\pm}25.64$). The increase in the SCM was greatest, followed by increases in the RA, EO, and PM CONCLUSION: These finding suggest that activity of accessory respiratory muscles increases with use of elastic bands during chest expansion exercise in cerebral palsy.

Eventration of the diaphragm is, by definition, abnormally high or elevated position of diaphragm as a result of paralysis, aplasia or atrophy of varing degrees of muscle fibers, and the cause of which may be congenital or acquired. The unbroken continuity of the diaphragm differentiates it from diaphragmatic hernia. The clinical manifestations of the condition, if present, are usually due to the interference of the ventilatory function of the lung and digesive dysfunction due to gastrointestinal distorsion. Treatment consists of surgical repair of the relaxed diaphragm to it`s normal position. A ease of left sided eventuration of the diaphragm, 31 year old officer, was found by chance after traffic accident with chief complaints of hemoptysis and multiple superficial contusions. Routine chest roentgenogram and barium study of the colon revealed moderately elevated left hemidiaphragm with displacement of the splenic flexure of the colon into the left chest. Past history revealed frequent attack of upper respiratory infection and some abnormal condition on his left chest announced by screen cheek of chest X-ray at the time of entrance for his army service 3 years before. Plication of the relaxed diaphragm through left thoracotomy was done and result was excellent as seen on Fig. 5. Cause of eventration of the left hemidiaphragm was due to paralysis of the left phrenic nerve which was tested during thoracotomy.

In this study, we proposed pathological pattern detection system for X-ray chest image using artificial neural network. In a physical examination, radiologists have checked on the chest image projected the view box by a magnifying glass and found out what the disease is. Here, the detection of X-ray fluoroscopy is tedious and time-consuming for human doing. Lowering of efficiency for chest diagnosis is caused by lots mistakes of radiologist because of detecting the micro pathology from the film of small size. So, we proposed the method for disease detection using artificial neural network and digital image processing on a X-ray chest image. This method composes the function of image sampling, median filter, image equalizer used neural network and pattern recognition used neural network. We confirm this method has improved the problem of a conventional method.

The purpose of this study was to establish the proper amount of eases according to the body type of men's bodice basic pattern. The 3 subjects in 30's men were selected for developing fitted pattern for each type. And the results of the wearing test for individual subject by distributing ease amount are as follows. The wearing test is administrated by a division of 12cm, 15m, and 18cm areas respectively after separating the fitted pattern for each type in a vertical and horizontal ways. There exists a significant difference in ease according to the measures of chest circumference of subjects. Also, it is shown that the more comfortable in function, the better visible in appearance as the ease gets proper. As to regions, the amount and ratio of ease chest circumference are increased in proportion to the size of the chest circumference. The scye depth is affected by the ease of chest circumference, while the ease of the interscye and the back breadth are lessened due to the effect of their appearances. And the side breadth is required as a buffer to complement the shortage of the interscye and the back breadth because the ease of either the interscye or the back breadth is partially transferred in motion.

PURPOSE: The purpose of this study suggests the exercise programs for improving the function and structure by applying the Schroth exercise method and sling exercise method to the scoliosis patient. METHODS: The subjects were 16 patients who were diagnosed with scoliosis. They were randomly assigned either to a Schroth exercise group (n=8) that received Schroth exercise program or to a sling exercise group (n=8) that received sling exercise program. Flexibility, static balance, dynamic balance, and spinal angles were measured by using the modified sit and reach test, one leg standing with closed eyes, functional reach test, and Cobb's angle, respectively. The chest expansion were calculated using differences of chest circumference between maximum inspiration and maximum expiration measured under armpits, at the junction between the sternum and xiphoid process, and at the waist. RESULT: Schroth group before and after the intervention there was a difference in the static balance, spine angle, chest expansion (p<.05). sling group before and after the intervention there was a difference in the flexibility, static balance, spine angle, chest expansion (p<.05). There were significantly differences between the both groups for chest expansion thoracic level inspiratory variables at post-exercise. CONCLUSION: These results revealed that two exercise program improved flexibility, static standing balance, spine angle, chest expansion level and ability used as scoliosis management and intervention. Therefore, it is expected to be used as a method for the treatment and prevention in the process of rehabilitation of patients with scoliosis.

There was cross-sectional study on investigating the factors related asbestos-related disease on chest radiograph of workers exposed to asbestos in ship repair. According to Occupational Safety & Health Administration asbestos standard, medical surveillance, chest radiologic study, pulmonary function test and medical questionnaire are performed in 118 subjects exposed to asbestos for 10 years or more in ship repair. The sixteen out of 118 subjects $(13.6\%)$ were observed asbestos-related disease finding on chest radiography. Significant factors related to those finding on chest radiography were abnormal pulmonary function test, cough, sputum, past history of respiratory disease, work duration. Workers with Significant factors related asbestos-related disease finding on chest radiography should be managed on a strict program. Further, factors unrelated with asbestos-related disease finding on this study should be evaluated prospectively for medical surveillance program of workers exposed to asbestos.

This research was accomplished to assess dose effects on image quality at computed radiography (CR). The ultimate target of the research was finding optimized exposure that provides necessary image quality for the clinical chest diagnosis. Modulation transfer function (MTF), normalized noise power spectrum (NNPS), and Noise equivalent quanta (NEQ) corresponding to the different doses were measured for the assessment of image quality. The preparation of "edge test device" used in MTF measurement and experimental geometry setup were followed by the recommendations of International Electrotechnical Commission (IEC). The experimental results show the necessary image quality can be achieved even at a half of the automatic exposure control (AEC) setting dose for chest diagnosis. It means that the patient exposure can be reduced dramatically by using optimized dose.

Pulmonary alveolar proteinosis (PAP) is a rare disorder that's characterized by accumulation of surfactant components in the alveolar space. Idiopathic PAP is recognized as an autoimmune disease that's due to impaired alveolar macrophage function and this caused by autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). We report here a case of pulmonary alveolar proteinosis that was deemed interstitial lung disease at the initial diagnosis. A 61-year-old man presented with intermittent blood tinged sputum and dyspnea on exertion. The man was a painter for 30 years and he had a 10 pack-years smoking history. Chest computerized tomography (CT) revealed multifocal ground-glass opacity with interstitial thickening at both lungs. His pulmonary function tests and methacholine test revealed non specific results. He was diagnosed with interstitial lung disease on the basis of the chest CT finding and occupational history. However, seven months later, his symptoms progressed. Follow-up chest CT was performed. Wedge resection via video-assisted thoracoscopic surgery (the anterior basal segment of the left lower lobe) was done. Microscopic examination showed large groups of alveoli with excessive amounts of surfactant and a complex mixture of protein and lipid (fat) molecules. Finally, he was diagnosed as having pulmonary alveolar proteinosis.

PURPOSE: The purpose of this study was to compare the effect of depending on the location of applying chest expansion resistance exercise on the respiratory muscle strength stroke patients, and to suggest more effective interventions to improve respiratory function in stroke patients in clinical practice. METHODS: A total of 30 subjects were selected and divided into two groups, and chest cage extension resistance exercise was applied to the sternum and rib cage, respectively, and performed for 4 weeks, 3 times a week, for 20 minutes. In order to compare the general characteristics of the study subjects and the homogeneity of the group, the pre-experimental values were analyzed using the independent sample t-test. Paired-sample t-test was used for pre-post value comparison of maximum inspiratory pressure and maximum expiratory pressure in each group. Statistical significance was set to .05. RESULTS: Both the sternum application group and the rib cage application group showed a significant difference in the maximum inspiratory pressure according to the intervention. Also, there was a statistically significant difference in the maximum expiratory pressure in the sternum application group. CONCLUSION: As breathing exercise is important for stroke patients, based on the results of this study, if therapists perform sternal extension resistance exercise or rib extension resistance exercise according to the patient's condition and environment, it can help the breathing function of stroke patients.
