By implementing epoch-making policies for industrial promotion, the national economy has made a remarkable development. As a result of such economic growth, industrial accidents and occupational diseases have become a serious problem in Korean society. In the presidential order for the execution of the Korean Labor Standard Law, neuritis and other diseases stemming from health impairments due to vibrations in industrial processes are designated to be dealt with as vibration diseases. In the case of vibration disease, industrial accident compensation is not effectively paid. In order to investigate the vibration hazards of rock-drill operation, the authors studied the subjective symptoms and performed physical function tests on a total of 79 persons (vibration exposed group) who used rock-drills, and 39 persons (control group) who did not use rock-drills at anthracite mines. The results of the physical function test were as follows : 1. The right hand was more affected by white finger than the left hand. 2. Independent variables such as duration of rock-drill operation, age, drinking and smoking were identified as statistically significant factors for the occurrence of white finger. 3. In the pain sense threshold, the group with Raynaud's phenomenon showed a statistically higher level than that of the control group. 4. The skin temperature of the group with Raynaud's phenomenon was lower than that of the control group. The recovery time of skin temperature after cooling was delayed compared with the value of the control group.

The carpal injury is difficult to diagnose due to anatomical complexity and the like. So, in order to get radiological knowledge of normal wrist, the authors measured the values which will be described on the wrist PA and lateral roengenogram obtained from 440 normal wrists(male : 188 cases, female : 252 cases) in randomly selected patients. The following results were obtained. l. Ulnar variance(mm±standard deviation): Total 1.1±1.2 : negative variance : 9.3%, positive variance : 56.1%, 2. Scapholunate Gap(mm±standard deviation): Total 0.4±0.7, 3. Ulnar Tilt(degrees±standard deviation): Total 23.6±5.3, 4. Volar Tilt, 5. Carpal height rstio : Total 0.52±0.05 male 0.53±0.04 female 0.51±0.05 : Total 13.1±5.9, 6. Carpal ulnsr distance ratio Total 0.05±0.05, 7. Scapholunate Angle : Total 49.9'±10.1', 8. Capitatolunate Angle Total 17.5'±10.0', 9. Radiolunate Angle Total 8.8'±6.7', 10. Carpal width ratio Total 0.72±0.08 11. Carpal thickness ratio Total 0.49±0.07.

The purpose of this study was to compare the hospital charges of long-term and those of short-term inpatients Insured by the Industrial Accident Compensation Insurance System. This study analysed 1,597 medical bills of injured workers emitted to and discharged from all hospitals in Korea in the period between March 1, 1988 and May 30, 1989. The 308 workers hospitalized for more than 50 hospital days were classified as long-term inpatients, and the others as short-term inpatients. The sampling method employed was 25% systematic sampling. The results of this study were as follows; 1. The average length of stay for long-term inpatients was 95.1 days, and 20.7 days for short-term inpatients, 2. Long-term inpaiients' main diseases were multiple injury and fracture. Fracture of the lower extremities and feet prevailed, 3. Daily hospital charges were higher in the long-term inpatients than in the short-term inpatients. 4. Total charges decreased depending upon hospital grade in the order of general hospital, hospital, and clinic. Daily average hospital charges were the same regardless of hospital grade. 5. The proportions of long-term Inpatients admitted to general hospitals, hospitals, and clinics were 46.1%, 23.4%. and 30.5% respectively, and those of short-term patients were 33.2%, 24.1%, and 42.7% respectively. 6. Multiple regression analysis revealed that the length of hospital stay, hospital grade, treatment results and patient's age were the major determinants of hospital charges.

We report one case of adenoma malignum of the cervix. Adenoma malignum is an extremely well-differentiated form of adenocarcinoma in which the branching glandular pattern strongly simulates that of the normal endocervical glands. This term has been used to describe a very well-differentiated adenocarcinoma characterized histologically by distorted and architecturally irregular endocervical glands which penetrate deeply into the wall of the cervix, but with minimal and focal evidence of glandular cell stratification, anaplasia, or mitotic activity. Despite this innocuous histologic appearance, these tumors have classically been thought to be clinically highly malignant, with an almost invariably rapid lethal outcome. The diagnosis of minimal deviation adenocarcinoma (adenoma malignum) of the endocervix may be difficult. The diagnosis was adenocarcinoma on the Pap Smear treatment has been hysterectomy.

A recent increase in hospital cost in Industrial Accident Compensation System has caused an issue. Especially the many problems in assessing and paying hospital cost have made necessary improvement measures on this. For this purpose the study analyzed 179,442 medical bills for industrial accident patients during 1986~1988. And various annual statistic data, references and documentations are also reviewed. The results of this study were as follows: 1. The average days for medical treatment per injury decreased depending upon hospital grade in the order of clinic, hospital, and general hospital, and the average hospital charges per injury decreased in the order of general hospital, hospital and clinic. 2. The inpatients' leading injury was traumatic amputation of fingers, and the open wound of fingers came to leading injury among the outpatients. The proportions of 10 leading injuries among inpatients and outpatients were 42.7% and 49.2% respectively. 3. As a consequence of the analysis of average medical charges, fractures of neck of femur in inpatients, and intervertebral disc disorders in outpatients were obtained as the most prevalent injuries. The coal workers' pneumoconiosis and injury to nerve roots and spinal plexus were most prominent injuries with repect to the days for medical treatment. 4. According to annual days for medical treatment, fracture of tibia and fibula was the most prevalent in inpatients, and sprains and strains of back was the most prevalent in outpatient. Traumatic amputation of fingers and other 10 leading injuries has a 42.6% share of total inpatients' hospital charges, and fracture of phalanges of hand and other 10 leading injuries possessed 53.4% of total outpatients' hospital charges. 5. Multiple regression analysis revealed that length of hospital stay, number of revealed that length of hospital stay, number of radiologic examinations, duration of operation, age, and others were the major determinants of total hospital charges. A comparision with medical insurance and car insurance for hospital charges and days for treatment showed 2-4 times higher than medical insurance, but showed 0.4~1.0 times lower than medical insurance and car insurance for daily treatment charges.

The vascular reaction such as the indirect blood pressure and the pulse rate of the tail to the noise were examined in 8 naive Sprague-Dawley rats of both sexes. The sounds used in the experiment were 1KHz and 4 KHz, 95dB pure tone generated by Nagashima Audiometry. The indirect blood pressure and the pulse rate were checked at the rat tail by Polygraph at 5 minutes interval. The results were as follows: 1. The blood pressure and the pulse rate increased maximally 5 minutes after the exposure to both sounds. 2. The blood pressure and the pulse rate returned normal range within 20 minutes after the exposure of both sounds. 3. The increment of the blood pressure and the pulse rate was greater after the sound of 4KHz than after that of 1 KHz, but it wasn't statistically significant.
