With the adevance of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. We have experienced these diseased of the 3 cases in our department. The first case was a 25 year old male who was severe dyspneic and subcutaneous emphysema, hemoptysis, and hemopneumothorax of both side were noted. During tracheostomy, it was found that the 2net ring of the trachea was ruptured. No definitive procedure was made on admission. Corrective surgery was performed with end-to-end anastomosis on 31 post-traumatic day. The second case was a 43 year old female who received multiple stab wounds on the anterior neck and it was found that the cricoid cartilage was transected partially. The injured cartilage was approximated with interrupted suture of No. 600 wire. The third case was a 19 year old male who had sustained a compression chest injury without external wound or rib fracture. At five days after trauma, he had suffered from dyspnea, and obstruction of the left main bronchus due to traumatic bronchial rupture was confirmed by means of bronchoscopy and bronchography at two weeks after the trauma. End-to-end anastomosis of the bronchus was performed and the left lung was aerated well. Mild postoperative stenosis of trachea was remained in the first case. Others were uneventful.

This is a report on a total of 8 cases of benign mediastinal tumors and cysts in Department of Thoracic Surgery, Chonnam University Hospital during the period from 1961 to 1969. The patients age was distributed between 18 and 38 year old with the highest incidence in the age group of second decade. Sex ratio of male to female was 3: 5. The tumors were classificed as follow; 3 case:, of neurogenic tumors, 2 cases of teratomas, one case of pericardial cyst, one case of cystic hygroma, and one case of brochogenic cyst. The symptomatic patients were 5 cases(62. 6%) and asymptomatic patients were 3 cases(37.5%). The symptomatic patients had the symptoms not referable to their lesion and the mediastinal tumors of asymptomatic patients were incidently found by routine chest X-ray. The Symptoms occurred by compression to adjacent nerve system in 3 cases. by perforation into the lung with infection in one case and by infection of bronchial cyst in one case. The complications were Pancoast's syndrome including Horner's syndrome(2 cases), middle lobe syndrome (one case), bro:1chial infection(one case) and intercostal neuralgia(one case). All tbe tumors were surgicai[y resectable with good recovery postoperatively. In 5 cases of the symptomatic patents, their symptoms were disappeared dramatically after operation.

Bronchogenic cysts are rare congenital anomalies that arise early in gestation from abnormal budding of the developing respiratory system. Mediastinal bronchogenic cysts account for 10-15 percent of all primary mediastinal masses; 63.7 percent of patients are symptomatic. Common symptoms are fever, chest pain, cough, dyspnea, and dysphagia. Gastrointestinal symptoms except dysphagia are rare. It can be life threatening with compression, infection, hemorrhage, or rupture. Symptoms and signs of compression are more frequent in infants and children than in adults. It may be asymptomatic, or cough, infection, and hemoptysis may be observed. Complete excision is recommended. We report a case of bronchogenic cyst misdiagnosed as chronic gastritis with nausea and epigastric pain for a year.

Retroesophageal aortic arch, in which the aortic arch crosses the midline behind the esophagus to the contralateral side, is a rare form of vascular anomaly. The complete form may cause symptoms by compressing the esophagus or the trachea and need a surgical intervention. We report a rare case of a hypoplastic left heart syndrome variant with the left retroesophageal circumflex aortic arch in which the left aortic arch, retroesophageal circumflex aorta, and the right descending aorta with the aberrant right subclavian artery encircle the esophagus completely, thus causing central bronchial compression. Bilateral pulmonary artery banding and subsequent modified Norwood procedure with extensive mobilization and creation of the neo-aorta were performed. As a result of the successful translocation of the aorta, the airway compression was relieved. The patient underwent the second-stage operation and is doing well currently.

In this study, we tried to find out the difference in confidence in performing Healthy Life on CPR before and after CPR education to middle school volunteers. Through the above statistical analysis process, the following findings were obtained: First, the general characteristics of the respondents who participated in this survey were higher than that of boys, followed by third, first and second graders. Second, junior high school volunteers were shown to have similar confidence (Chonbach's α=.80) and confidence (Chonbach's α=.76) before CPR education, and confidence in the degree of social contribution (Chonbach's α=7.77). Third, the Pearson Rates Correlation was performed to see the correlation between grade, gender, pre-education confidence, post-training confidence, confidence in the application of airway methods, confidence in the patient's breathing, confidence in chest compression, confidence in the use of defibrillators, and post-cardiopulmonary resuscitation education. As a result, it was confirmed that there was a significant correlation between all the spokesmen. In particular, post-training self-confidence was the highest correlation with coping confidence in case of cardiac arrest, followed by chest compressive confidence. Comparing and reviewing these findings and prior studies as shown above, we were able to establish that CPR education has an impact on the confidence performed by gender.

Recently, the importance of CPR training for the layperson has been emphasized to improve the survival rate of out-of-hospital cardiac arrest patients. An accurate and realistic training strategy is required for the CPR training effect for laypersons. In this study, we develop an extended reality (XR) based CPR training system and evaluate its usability. The XR based CPR training system consisted of three applications. First, a 3D heart anatomy image registered to the manikin is transmitted to the smart glasses to guide the chest compression point. The second application provides visual and auditory information about the CPR process through smart glasses. At the same time, the smartwatch sends a vibration notification to guide the compression rate. The 'Add-on-kit' is a device that detects the depth and speed of chest compression via sensors installed on the manikin and sends immediate feedback to the smartphone. One hundred laypersons who participated in this study agreed that the XR based CPR training system has realism and effectiveness. XR based registration technology will contribute to improving the efficiency of CPR training by enhancing realism, immersion, and self-directed learning.

A 12-years-old female admitted to the hospital with the complaint of pain on the right upper chest area which persisted about 1 month prior to admission. $Caf{\acute{e}}$-au-lait spots of various size laying on a whole body and freckling on the axilla were found on physical examination. A huge mass was found on the plain chest X-ray and on chest MRI. The mass encroached thoracic spine, posterior rib, back muscles, and then into the neural canal and compressed thoracic spinal cord. On the 5th day of hospitalization, the patient complained tingling on the both legs and 2 days later, monoparesis on the right leg. Open thoracotomy and decompressive laminectomy was done to remove mass. Pathologic reports confirmed rhabdomyosarcoma, embryonal type.

Background: Surgery has been the classical treatment of pectus carinatum (PC), though compressive orthotic braces have shown successful results in recent years. We propose a non-operative approach using a lightweight, patient-controlled dynamic chest-bracing device. Materials and Methods: Eighteen patients with PC were treated between July 2008 and June 2009. The treatment involved fitting of the brace, which was worn for at least 20 hours per day for 6 months. Their degree of satisfaction (1, no correction; 4, remarkable correction) was measured at 12 months after the initiation of the treatment. Results: Thirteen (72.2%) patients completed the treatment (mean time, $4.9{\pm}1.4$ months). In patients who completed the treatment, the mean overall satisfaction score was $3.73{\pm}0.39$. The mean satisfaction score was 4, and there was no recurrence of pectus carinatum in patients who underwent the treatment for at least 6 months. Minimal recurrence of pectus carinatum after removal of the compressive brace occurred in 5 (38.5%) patients who stopped wearing the compressive brace at 4 months. Conclusion: Compressive bracing results in a significant improvement in PC appearance in patients with an immature skeleton. However, patient compliance and diligent follow-up appear to be paramount for the success of this method of treatment. We currently offer this approach as a first-line treatment for PC.

The purpose of this research was to evaluate retention of cognitive knowledge, psychomotor skills and self-confidence on CPR 3 months after CPR training program. The sample consisted of 39 nursing students. We provided one rescuer CPR training program for nursing college students on the basis of AHA. The questionnaires for knowledge of CPR were developed 50 items based on AHA guidelines. Self-confidence were checked by 11 items questionnaires. The accuracy of CPR skills were checked by Skillreporter CPR training manikin and by researcher's evaluation based on CPR skill checklist. The results were as follows ; 1. The majority of participants didn't have any previously experiences of CPR training (76.9%). Only 15.1% previously took the CPR training with CPR practice. 2. In terms of self-confidence of CPR. The score were increased for 2 days (p>.001) but retention of self confidence was significantly statistical decreased in 3 months after training (p<.001). 3. There was a statistically significant decrement in mean of knowledge of CPR between 2 days and 3 months after CPR training (p<.001). 4. There was a statistically significant decrement in cognitive knowledge of CPR based on CPR skills checklist(p<.001). 5. Retention scores of psychomotor skills of CPR 3 months after training were 42.10% in numbers of adequate ventilation, 52.81% in numbers of adequate chest compression (p<.001) respectively. 6. Retention of passing rate on chest compressions of CPR 3 months after training was 27% (p<.001), on ventilation was 2.63% (p>.001). The error items with statistically significant differences 3 months after CPR training were too little ventilation (74.36%) and too little chest compressions (92.31%). The results of the study suggest that we need further evaluation of course components which could improve retention of CPR for all trainees.
