A respiration measurement system for vital signs was developed. Respiration signals were measured, processed, and analyzed. Four electrodes, attached on the surface of the skin, were used to monitor respiration signals by impedance pneumography. The measured signals were amplified, detrended, filtered, and transferred toan embedded module. The Kalman filter was used to remove motion artifact from the respiration signals. Experiments were conducted at stable condition and walking condition to evaluate the performance of the system. Respiration rates of five males and five females were measured and analyzed at each condition. The referenced respiration signal was determined by temperature of nose surroundings. The results showed that the respiration rates at the walking condition had more motion artifacts than the stable condition. The accuracies of the respiration measurement system with Kalman filter were found as 96% at the stable condition and 95% at the walking condition. The results showed that the Kalman filter was an effective tool to remove the motion artifact from the respiration signal.

Purpose : The Purpose of this study was on determine whether thoracic expension exercise might increase the pulmonary function of the patients with stroke. Methods : Fourty paients with stroke were randomly assigned to experimental(n=20) and control group(n=20). During four weeks, each group participated thirty minutes for five times per week. Subjects were assessed using pre-value and post-value measurement pulmonary function(Forced vital capacity, Forced expiratory volume at one second, FEV1/FVC, Peak expiratory flow, Tidal volume, vital capacity, Inspiratory capacity, Expiratory reserve volume, Inspiratory reserve volume). Results : These finding suggest that experimental group was significant increase in FVC, FEV1, PEF, TV, IC, IRV, ERV($p$<.05). In comparison of two group, experimental group was high pulmonary function than control group. Conclusion : This study showed experimental group can be used to improve pulmonary function than control group. Thus it indicates that the thoracic expension exercise will be more improved through the continued respiratory exercise program.

Some extensive thoracic aortic aneurysms are not amenable to staged repair, such as extremely large distal aortic aneurysms that are unsuitable for an elephant trunk anastomosis, or aneurysms that are accompanied by complications such as ruptured descending thoracic aneurysm. We report here a case of successful replacement of the aorta from the ascending to the descending aorta in one operation. The patient was 65-year-old man who had an aneurysm which involved the entire thoracic aorta and ruptured in the descending aorta. The operation was performed via transverse thoracosternotomy, and under the deep hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully and was discharged without any neurologic complications.

PURPOSE : The purpose of this study to suggest the exercise programs for improving the function and structure by applying the Masan university scoliosis program exercise method and electrical therapy method to the scoliosis patient. METHODS : The subjects were 18 patients who were diagnosed with scoliosis. They were randomly assigned either to a Masan university scoliosis program exercise group (n=11) that received Masan university scoliosis program exercise program or to a electrical therapy group (n=7). Flexibility, static balance, dynamic balance, and spinal angles were measured by using 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. RESULT : Masan university scoliosis program group before and after the intervention there was a difference in the static balance, spine angle(p<.05). Masan university scoliosis program group before and after the intervention there was a difference in the flexibility, static balance, spine angle, chest expansion (p<.05). CONCLUSION : These results revealed that Masan university scoliosis program exercise program improved flexibility, static standing balance, spine angle, 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.

From August 1990 through December 1991, 14 patients[all males] underwent int-rathoracic muscle transposition of extrathoracic skeletal muscles to treat empyemas, 6 patients had tuberculous empyemas, 4 had chronic empyemas of unknown etiology, 3 had pos-tpneumonectomy empyemas, and 1 had postlobectomy empyema. 9 patients had associated bronchopleural fistulas, Their ages ranged from 22 to 67 years, with mean age of 45.1$\pm$17. 6[$\pm$S.D] years. The serratus anterior was transposed in 13 patients, the latissimus dorsi in 12. In 11 patients, both the serratus anterior and the latissimus dorsi were transposed. The omental flap also transposed in 3 patients. To reduce the dead space in the thoracic cavity, thr-oacoplasty was also carried out in 10 patients. The number of the partially resected ribs was 3.0$\pm$0.8[$\pm$S.D.]. All operations were single stage procedures, and all wounds were closed primarily, with no permanent tubes or chest wall openings. There was no hospital mortality, and so no subsequent operation has been required. Follow-up of the patients ranged from 5 to 16 months with a mean of 9.2$\pm$3.1[$\pm$S.D] months, All the patints had no further signs or symptoms of the original infection after discharge. We conclude that intrathoracic transposition of extrathoracic skeletal muscle is an excellent method of treatment for persistent, life-threatening intrathoracic infections.

Spontaneous pneumothorax is usually seen in young adult male. And typically, the patient is a tall, thin, 20- to 30-year-old male. Usually the pneumothorax results from rupture of a pulmonary bleb. Author reviewed 66 cases of spontaneous pneumothorax experienced in the Dept. of Thoracic & Cardiovascular Surgery, Pusan National University Hospital, since Jan., 1980 to Aug., 1986. The clinical data were summarized as follows: 1. The age distribution of spontaneous pneumothorax: 17 to 34 years old and mean age was 25.3 years. 2. The sex distribution of spontaneous pneumothorax: 52 in men, 14 in women and the ratio was 3.7:1. 3. Chest dimension in male patients: Maximum posteroanterior distance [MPA], MPA/Maximum width [MW]: Significantly smaller than control group. Distance from second to tenth rib on left [L2-10], Distance from second rib on right to diaphragm [R2-D], R2-D/MW: Significantly larger than control group. 4. Chest dimension in female patients: MPA, MW: Significantly smaller than control group. Distance from second rib on left to diaphragm [L2-D], Distance from second to tenth rib on right [R2-10], R2-D, L2-10/MW, L2-D/MW, R2-10/MW, R2-D/MW: Significantly larger than control group.

Hibernoma is a rare, benign soft tissue tumor that is derived from the remnants of fetal brown tissue. The term hibernoma was proposed in 1914 by Cery because of its morphologic similarity to the cel s of the so-called hibernating gland of animals. The most common site of hibernomas is the subcutaneous tissue of the back, especially the interscapular area. These tumors are considered benign and malignant transformation has not been reported. We experienced a case of hibernoma, 60-year-old woman had suffered from the palpable mass without pain or tenderness on posterolateral lower chest wall, left. The tumor was extirpated under the impression of angiolipoma, but was confirmed hibernoma. She was discharged without complication.

The 242 patients were operated due to chronic empyema in Hanyang University Hospital From Jan, 1983 to Aug, 1991, we operated 17 patients by modified.Schede`s thoracoplasty with myoplasty and we concluded to next scentences. 1. The age of patients were varied from 28 to 65[Average 39.1] and male preponderance was seen[more than 3 times]. 2. The preoperative cause of disease were tuberculosis in 14 patients[3 patients were associated with aspergillosis, and 1 patient was associated vrith actinomycosis], lung abscess in 2 patients, and haemophilia in 1 patient. 3. The Preoperative duration of empyema were varied from 1 month to 30 years[Average 49.8 month], and the duration from pulmonary resection to thoracoplasty were 1 month to 13.5 years[Average 55 month] except 3 patients, who were operated pneunectomy with thoracoplasty at the same time. 4. The total number of thoracoplasty were 19, because in 2 patients, we operated 2 steps, and we failed in 6 cases, so the success rate was 68.5%. 5. In failure analysis of 6 cases, the cause were obliteration failure in 3 cases, inadequete drainage in 1 case, and in the other 1 case was mixed type. 6. From 1990 to 1991, there were no death associated with operation and there were 1 failure, so the success rate was greatly improved. 7. The bronchopleural fistula or spontaneous rupture of trachea were seen in 12 cases, and the success rate was high in absent cases.

Lung hernia is defined as a protrusion of lung parenchyma beyond the confines of the musculoskeletal thorax. To date, less than 300 cases have been reported in the literature. The patients were 37 & 57-year-old men who had traumatic rib fractures in the past, whose chief complaint was a painless soft bulging mass increased in size during expiration or coughing and diminished during inspiration or quiet breathing. The primary repair was performed without any p stoperative recurrance. We report two cases of acquired herniation of lung first time in Korea with a brief review of literature.
