Primary intrathoracic neoplasms occur frequently, and the most frequent intrathoracic tumors are of pulmonary or bronchogenic origin. Second in frequency are mediastinal tumors, and least frequency or comparatively rare are the neoplasms arising from the wall of the thorax and extending into the thoracic cavity. Of all intrathoracic tumors, fibroma is extremely rare. Recently, we have experienced a huge rapid growing intrathoracic fibroma originating from thoracic wall, which is removed successfully and confirmed histopathologically. Authors present one case of fibroma and discussion with a brief review of the relevant literatures.

Mitral valve disease is the most common disease of the acquired heart diseases, and atrial septal defect is also one of common congenital heart diseases. Coexistence of these two lesions is rare, but of great hemodynamic interest. Among 443 cases with mitral valve disease and 90 cases with atrial septal defect experienced in the Department of Thoracic Surgery, Seoul National University Hospital, there were 6 cases with atrial septal defect complicated by mitral valve disease. 1. Of the 6 patients, four were female and two were male. The age was ranged from 18 to 46. 2. Atrial septal defect was ostium secundum type in all cases, and the mitral valvular lesions were regurgitation in four and stenosis in two. Type II ventricular septal defect was also combined in one of the cases. 3. The atrial septal defect was corrected by, primary closure and the mitral valve was replaced with the prosthetic or bioprosthetic valve in all cases. The combined ventricular septal defect was closed using Teflon felt patch. 4. The operative result was good except in one who was expired of bacterial endocarditis 4 months after hospital discharge.

A clinical analysis was performed on 383 cases of chest injurjes experienced at Department of Thoracic Surgery, Seoul National University Hospital during 21 year period from 1957 to 1977. Of 383 patients of chest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle fracture, 26 of lung contusion, 17 of diaphragmatic laceration, 14 of hemopericardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury patients were traffic accident victims. and fails accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt chest injuries the patients with five or more rib fractures had a 85 per cent incidence-of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis [46 cases] and closed thoracotomy [125 cases] but open thoracotomy .had to be done on 90 cases [23-5%] because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronchial rupture. The over all mortality was 2.87 per cent [11 among 383 cases], 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.
심정지액을 이용한 개심술에 있어서 심근 ATP에 대한 실험적 연구

This study was attempted to evaluate the effectiveness of cold cardioplegic solution [group B] compared with that of intermittent aortic cross clamping [group A]. 1. In group A, two dogs recovered spontaneous heart beat without using defibrillator and one case was used defibrillator once. In group B, four dogs recovered the spontaneous heart beat even without defibrillator and in one animal the defibrillator was used three times. 2. There was no significant difference in serum electrolyte [Na+, Ca2+, Cl- ] between group, but K+ level was decreased in both group. 3. The group A showed more increasing in serum LDH activity than group B. 4. The postoperative myocardial ATP level was $2.35{\pm}0.10$ ${\mu}$M/Gm. of wet weight in control group, $1.46{\pm}0.16$${\mu}$M/Gm. of wet weight in group A [60.2% of control group], and $1.80{\pm}0.14$${\mu}$M/Gm. of wet weight in group B [76.8% of control group].
OSEK/VDX 기반 차량용 RTOS의 구현과 성능 테스트

As the architecture of automotive software is complicated and LOC of software increases, there is an increasing demand for standard operating system. OSEK/VDX defines an industry standard for automotive operating system and middleware. This paper introduces an implementation of RTOS(OSCAR-OSEK) based on OSEK/VDX standard. For better speed of scheduling, we suggest a new method for ready queue implementation considering the characteristic of automotive application software. Also we introduce a method for improving the portability of RTOS on various MCUs. And, we show OSCAR-OSEK implementation and performance test results.
