The purpose of this study is to investigate the relationship between the work postures and upper extremity cumulative trauma disorders(CTDs) in female medical insurance bill reviewers(n=448). This study included diagnosis for CTDs, anthropometry and job analysis (workstations and posture). The characteristics of subject were 33.6 years of average age and 8.7 years of average work duration. The results were as fallows. Ergonomic conditions of workstation were unsuitable compared with anthropometry result. The height of work surface(79.5 cm) and chair(43.0 cm)were high. work space was small, and legs space under the table was limited. Work postures were awkward compared with recommended neutral postures. Neck flexion($21.0-36.0^{\circ}$), elbow elevation, shoulder abduction ($46.0-47.0^{\circ}$). wrist radial and ulnar deviation, forearm supination and pronation, and wrist repeated motion(12.7-21.5 freq./min) were analyzed as hazardous risk factors by job analysis. The prevalence of CTDs was 32.8 % by medical diagnosis. The prevalence rate of CTDs in hazardous work posture group was significantly greater than safe work posture group both neck-shoulder (relative prevalence = 5.2, p<0.001) and wrist-hand (relative prevalence = 2.5, p<0.05).

We present the case of a 38-year-old woman admitted to our outpatient clinic with accelerating back pain and fatigue following a kick to her back by her husband. Upon arrival, we detected ST segment elevation in the D1, aVL, and V2 leads and accelerated idioventricular rhythm. She had pallor and hypotension consistent with cardiogenic shock. We immediately performed coronary angiography and found a long dissection starting from the mid-left main coronary artery and progressing into the mid-left anterior descending (LAD) and circumflex arteries. She was then transferred to the operating room for surgery. A saphenous vein was grafted to the distal LAD. Since the patient was hypotensive under noradrenaline and dopamine infusions, she was transferred to the cardiovascular surgery intensive care unit on an extracorporeal membrane oxygenator and intra-aortic balloon pump. During follow-up, her blood pressure remained low, at approximately 60/40 mmHg, despite aggressive inotropic and mechanical support. On the second postoperative day, asystole and cardiovascular arrest quickly developed, and despite aggressive cardiopulmonary resuscitation, she died.

A 66-year-old woman described a 6-month history of hoarseness after upper respiratory infection. She was a house wife and referred from an outside clinic under a diagnosis of vocal fold nodules. Strobovideolaryngoscopy revealed bilateral vocal fold lesions, and decreased mucosal wave of both vocal folds. She was brought to the operating room for microsuspension laryngoscopy. Under general anesthesia, dual intracordal cysts on left vocal fold were completely resected with microflap technique. The lesion on the right vocal fold turned out to be a reactive fibrous mass, which was also resected. Dual intracordal cysts were confirmed histopathologically. The one was an epidermoid cyst lined with squamous epithelium, and the other was a mucus retention cyst lined with cuboidal epithelium. Postoperative voice was acceptable by the patient and the mucosal vibration has much improved after the surgery.

Purpose: To investigate the effect of infant massage on stress, immune function and self-confidence in postpartum mothers. Method: From September, 2003 to February, 2004, 65 women who had delivered babies and were enrolled in the postpartum clinic were assigned to the experimental group or control group. In the experimental group, infant massage was given for 20 minute sessions twice a day from 4 days to 14 days after delivery. The instruments were Parental Stress Index, serum cortisol levels, WBCs, lymphocytes, and Self Confidence Scale. Results: Stress scores, WBCs and lymphocytes showed significant differences by the time, but there weren't significant differences according to the group and interactions between the group and the time. Cortisol and self-confidence scores showed significant differences by the time and the group. Conclusions: Applying massage to their newborn baby influenced cortisol levels of postpartum mothers. Therefore stress, cortisol, and immune functions in postpartum mothers should be generally screened and follow up studies are needed for the effective application of massage in postpartum mothers.

Objectives: The purpose of this study is to obtain the basic data for the development of maternal health care by analyzing the status and needs of service target persons in Timor-Leste. Methods: The subjects were selected through the non-probability sampling method applying the FGI. Researchers interviewed 3 maternal health service managers, 6 midwives at Gleno and Railaco Health Centers and 2 women between 15 and 45 years of age. Results: In the results of on-site visit of the delivery facility and the FGI, we found poor sanitation in delivery room, lack of medical equipment related to antenatal consultation and delivery. In the case of the health center manager, the public health center provides various maternity health services, but the lack of the staff has difficulty in providing the service and managing the subjects. Midwives asked for regular maintenance education. Women in child bearing age living in mountainous areas had poor access to delivery facilities and lack of awareness of delivery services. Conclusions: It is necessary to increase the maternity management rate through regular maternity and maternal health check service and application to maternal management database, to improve the sanitation of the maternity clinic in the public health center, to strengthen the midwife competency program.

Purpose: The purposes of this study are finding the elements for a fast determination of the need for a transfusion to a multiple trauma patient arriving at this clinic in the initial stage establishing objective bases for a doctor in an emergency department to determine the need for a transfusion immediately after a patient has arrived at the emergency department, and providing treatment by considering various factors based on the nine criteria suggested in the emergency room transfusion score (ETS). Methods: This study was conducted on 375 multiple-trauma patients who visited the Chosun University Hospital Emergency Medical Center and activated the Emergency Trauma Team from January 2010 to December 2013. The patients were divided into the transfused group and the non-transfused group by retrospectively analyzing their medical records. Subsequently, the medical records were examined using the nine items suggested by the ETS and the results were analyzed. Results: Three hundred seventy-five patients with multiple traumas visited the Chosun University Hospital Emergency Medical Center and activated the Emergency Trauma Team. Among them, 258 died and 117 recovered and left the hospital. The deceased patients consisted of 182 males and 76 females with an average age 45. Of the 375, 165 were transferred from other hospitals, and 245 were blunt trauma patients. One hundred sixty-nine patients were injured in traffic accidents, and 119 of those 169 who had systolic blood pressure less than 90 mm Hg died. Two hundred twenty-six (60.3%) out of the 375 patients with multiple traumas received an emergency blood transfusion and their average age was 48. The 375 patients consisted of 156 males, 151 who had been transferred from other hospitals, 218 who presented with blunt trauma, 134 who had been injured in traffic accidents, 156 who had a systolic blood pressure less than 90 mm Hg, 134 who scored higher than 9 points on the GCS, and 162 who had a stable pelvic fracture of these 143 died. Conclusion: During this study, 226 (60.3%) out of the patients with multiple traumas received an emergency blood transfusion. After analyzing the results related to emergency blood transfusion by using ETS, we found that an emergency blood transfusion had to be prepared quickly when patients were transferred from other hospitals when the systolic blood pressure was less than 90 mmHg. when abnormalities had been detected by ultrasonography and when the patient presented with a stable pelvic fracture.

We have experienced 2 cases of the hunshot wound sof the chest involving cardiac injuries at department of the thoracic surgery, Capital Armed Forces General Hospital during I year from April I 1979 to Jan. 1980. In one case of two patients , he was a 22 years old man who was transported to this emergency room 4 hour 10 minutes after having gunshot wound of the left chest by helicopter. Physical examination showed small inlet in left 3rd ICS and left parasternal border, large outlet in left 8th ICS and left scapular line, no breath sound on left side and distant heart sound. chest roentgenography demonstrated marked pleural effusion in left side and mediastinum shifted to right. As soon as chest X-ray was taken, the bleeding through penetrating wound became profuse and cardiac arrest ensued. Closed chest cardiac massage was started and vigorous transfusion continued, but no effective cardiac activity could not be obtained. The patient was pronounced dead due to exsanguinating hemorrhage from wuwpected cardiac wounds. In this critically injured patient with evidence of intrathoracic hemorrhage and suspected cardiac penetration, only emergency thoracic exploration and immediate surgical control of bleeding points might offer the maximum possibility of survival. The other case was a 23 years old man who was transferred to the emergency room 4 hours 50 minutes after having kmultiple communicated fractures of sternum and linear fracture of right mandible by a missile. Examination revealed about 30% skin loss of the anterior chest wall, weak pulse of 96 beats/min., distant heart sound and decreased breath sounds bilaterally. finding on the chest X-ray films showed multiple sternal fractures, marked pericardial effusion indicating hemopericardium. So, the patient was moved immediately to the operation room where, after endotracheal tube inserted, a median sternotomy was performced. A hemorrhagic congestion of the right upper lobe and marked bulging pericardium were disclosed. The pericardium was opened anterior to right phrenic nerve and exsanguinating hemorrhage ensued from the 0.5cm lacerated wound in the auricle of right atrium. The rupture site of right atrium was occluded with non-crushing vascular clamps and then was over sewn with interrupted sutures. It was thought to be highly possible that he was alive long enough to have cardiorrhaphy because of cardiac tamponade, which prevented exsanguinating hemorrhage. He was taken closed reduction for linear fracture of right mandible 2 weeks after repair of ruptured right auricle in dental clinic. This patient's post-operative course was not eventful.
