A 23-y-o male patient was suffered from intermittent fainting and dyspnea on exertion [NYHA Class IIIIV]. 2-D - Echocardiogram and cardiac catheterization with cineangiogram showed typical IHSS findings those were asymmetrical septal hypertrophy [ASH], systolic anterior motion of anterior mitral leaflet [SAM] which induced mild mitral regurgitation [Seller Grade I/IV] and pressure gradient about 60 mmHg between left ventricle and the aorta. Medical treatment with 8-adrenergic blockade [propranolol] and Ca" channel antagonist [Verapamil] had no response. So, we performed trans-aortic ventricular septal myotomy and mymectomy. Resected rectangular muscle bar was 1 Cm x 1 Cm x 4.5 Cm. Post-operative pressure gradient between the left ventricle and the aorta was less than 10 mmHg and SAM. was disappeared with decreased mitral regurgitation grade. Post-operative course was smooth and his symptoms and signs were free without any medication during 12 months follow-up.w-up.

Congenital pericardial defect is a rare anomaly, which was first described by M. Columbus in 1559. Four hundred years later the first clinical diagnosis was reported by Ellis et al. The congenital pericardial defect Is usually asymptomatic and Is found Incidentally at thoracotomy and autopsy, but it appears that partial absence of pericardium Is not Innocuous because of sudden death due to herniation of a portion of heart. We experienced congenital left pericardial defect in 20 year old female who was diagnosed as left ventricular aneurysm before operation. This patient complained of dyspnea on exertion and anterior chest discomfortness. Physical examination revealed Grade II pansystolic murmur on the 3rd and 4th intercostal space left sternal border. There were specific abnormal findings on the chest plain film, EKG, ultrasonography, and left ventriculography. On 9th July 1981, an operation was performed and found the left partial pericardial defect through which a large portion of left ventricle was herniated Into left pleural space. The method of operation was removal of adhesion and widening of the pericardial defect to avoid Incarceration. After operation, we observed marked Improvement of symptoms and disappearance of cardiac murmur.

Thirty seven patients with ostium secundum atrial septal defect, operated from January, 1976 to September, 1984 at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, were given clinical assessment. The following results were obtained. 1.Ostium secundum atrial septal defect was comprised of 18% of congenital heart disease. Their mean age was 15.7\ulcorner.42. Sex ratio [male:female] was 1:1.1. 2.Most frequent clinical symptom was dyspnea on exertion occurred in 26 patients [76.5%]. Only one patient had no symptom [2.9%]. 3.Pre-operative EKG findings revealed RVH in 61.8%, ICRBBB in 29.4%, and RAD in 41.2%. 4.Mean value of systolic pulmonary arterial pressure in patients over 20 years old was 37.8\ulcorner4.4mmHg and it was 28.1\ulcorner10.2mmHg in patients under 20 years old, but the difference between two groups was not statistically significant. 5. In large defect group [>3cm in diameter], Qp/Qs was significantly increased than small defect group [<3cm in diameter], but systolic pulmonary arterial pressure and Rp/Rs were not different between two groups. 6. Overall operative mortality was 5.4%.

Four patients with funnel chest deformity corrected in the Department of Thoracic Surgery, Seoul National University Hospital are presented. The first case was a 21-year old female with cyanosis, clubbed fingers and systolic murmur on the left infrascapular region on physical examination associated with agenesis of the right lung. The deformity was of asymmetrical funnel chest, in which the left hemithorax was more sunken. She was corrected by the method of Funnel Costoplasty of Wada. The second case was a three years old boy whose anterior chest wall was symmetrically deformed, and he was corrected by the method of Ravitch using Adkins strut under the sternum. The third was a 22-year old man with symmetrical deformity, and was corrected by the method described by Shannon in 1973. The last patient was a 22-year old man and he had dyspnea on exertion, palpitation and apical systolic murmur with symmetrical funnel chest deformity. He was also corrected by Ravitch operation, All of them has excellent result.

Lipomatosis is a condition containing multiple lipomatous masses.Lipoma is a benign neoplasm composed of adult adipose tissue, and occur most often in the fifth or sixth decade and rarely in the pleura. Pleural lipomas are usually asymptomatic and revealed as an incidental roentgenographic findings. The patient was 59 year-old male and admitted because of dyspnea-on-exertion for 30 years. Chest CT revealed right pleural mass abutting on the chest wall, measuring minus 80 hounsfield units. The mass was resected with calcified pleural plaque and confirmed to be lipomatosis with collagenous fibrosis arising from viserai pleura.

The Work-Related Musculoskeletal Disorders(WMSDs) have been an rising issue since the 1970s. So many manufacturing companies have been tried to improve the work environments for the control and the prevention of the WMSDs. Specific risk factors associated with WMSDs include repetitive motion, heavy lifting, forceful exertion, contact stress, vibration, awkward posture and rapid hand and wrist movement. But recently it has reported that besides working conditions, job stress is the important hazard causes which lead to WMSDs. This study investigates the relation between WMSDs and Job stress from 1426 workers in Heavy Industry. Job stress was evaluated by Karasek's model. Job stress was associated with job satisfaction. Job demand was associated with the WMSDs, but job control was not associated with the WMSDs. The results can be used to design the management program for the WMSDs and the job stress.

In order to evaluate a health effect of air pollution, we designed exposure group (taxi driver, street sweeper, street trader,) and non -exposure group (office clerk). We analysed exposure and biologic marker by using personal sampler. Mean NO$_2$ and benzene level in each group were statistically significant. Also, respiratory symptom, chronic cough, sputum, and dyspnea on exertion were statistically significant in each group.

According to current record of private security in Korea, more than 107,963 private security guards are employed by 2,051 security guard association. However, it is obvious that there is lack of any kinds of professional license. To ensure the profession of Private Security industry and at the same time to improve the quality of private guard duty, it is necessary to introduce professional license system which is specialized and developed. The kinds of license anticipated are security guards services, armored car services, alarm services, proprietary security services, special guards services, terror, security consultants services, and private investigators. To settle those license system, there should be not only exertion of academic society but also administrative support of government and research of legal office th arrange legal and official structure.

The occlusive coronary artery disease presents a potential threat to a significant population in the United State. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. We experienced one case of coronary artery disease. He was a 68 year old male who had been suffered from hypertension since 1 5 years ago, and had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain on exertion, but this symptom was relieved on rest. Pre-operative EKG finding revealed no any other ischemic sign. Significant S-T segment depression was noted at lead II, aVF, V3, V4, and V5, and inverted T wave in V5 and V6 after Master`s test. Simple chest X-ray finding showed emphysematous field, bilaterally. Final pre-operative diagnosis was made by coronary angiogram, which showed almost 90% degree of occlusive lesion in the proximal part of left main coronary artery above the origin LAD artery. He was treated successfully by aorta-coronary saphenous vein graft under extra-corporeal circulation in May, 1987. He has been followed up with uneventful course.
