BACKGROUND: Rapid progress in medical science and technology has lengthened the average span of life in general population and accelerated the increase in the elderly. This gave rise to the expansion of chronic degenerative disease in the elderly, and then led to an increase in the utilization rate of health care facility and medical fee in sequence. METHODS: In order to grope for an effective control program of chronic degenerative disease and to find out the characteristics of disease structure and utilization patterns of health care facility in the elderly, the author analysed the 6,072,196 cases of insured medical record of Federation of Korean Medical Insurance Societies from January 1st to December 31st of the year 1991. RESULTS: Essential hypertension(5.94%) is the most common disease in the elderly. And what follows are gastritis and duodenitis(4.29%), acute bronchitis and bronchiolitis(3.68%), acute upper respiratory infection of multiple or unspecified site(3.47%) and diabetes mellitus(3.21%). Twenty most frequent diseases constitute the top 50.27% and one hundred constitute over 85% of all frequency of health care facility utilization. There are different patterns of diseases between two sexes. Pulmonary tuberculosis, chronic liver disease and cirrhosis, malignant neoplasm of stomach, chronic obstructive pulmonary disease, occlusion of cerebral arteries, sprains and strains of knee and leg, malignant neoplasm of trachea, bronchus and lung, other open wound of head, erythematosquamous dermatosis are more than 1.5 times higher in male by the standardized frequency ratio. There is a significant dissimilarity of disease structure between primary and other types of health care facility, which presents the point of reinforcement in primary care. The author has also noted elderly patients prefer secondary or tertiary health care facility in case of essential hypertension, diabetes mellitus, pulmonary tuberculosis, heart failure, duodenal ulcer, chronic liver disease and cirrhosis, funtional gastrointestinal disorder, hypertensive heart disease and chronic obstructive pulmonary disease which seems to be not so critical in most cases. CONCLUSIONS: Patients of chronic degenerative disease tend to pursue the high quality of medical care and irregularly utilize health care delivery system.

5.Experimental Investigations on the Effects of Ocular Tissues upon the Ultrasonic Waves.

Journal of the Korean Ophthalmological Society 1971;12(2):51-62
The purpose of this report is to investigate experimentally how the corea, sclera, crystalline lens and focusing lens influence the ultrasound intensity and beam width and to find characteristic differences due to the transducer parameters; frequency and size. A time-amplitude ultrasonic diagnostic apparatus, Aloka Model SSD-2D was used with transcucers of 10 MHz and 5 MHz, 10 mm and 5 mm diameters. The metal ball, 1 mm in diameter, was served as the echo-reflecting target which was immersed in water and moved horizontally under the transducer with a micrometer screw. The distances between the transducer and the metal ball varied from 10 mm to 50 mm in 10 mm step. The amplitudes curves of the echoes so obtained were represented by relative values. In water control experiment, the nearer the metal ball from the transducer, the more irregular the curves, with multiple amplitudes maxima and minima. These irregular curves became homogeneous as the transducer moved away from the target. The multiple peak curves were more marked when measured with transducers of higher frequency and larger diameter. At the end of the near field only a single peak was found in the axial portion of the sound field. In the far field, the beam width reduced slightly due to the divergence of the beam accompanied by slight attenuation of the echo amplitudes. When the sound beam passed through the cornea and sclera, the form of the curves remained almost unchanged, but the amplitudes decreased slightly due to the absorption of the sound energy. Scleral tissue absorbed the energy more strongly then the corneal tissue. When the crystalline lens was placed under the transducer, divergence of the beam and themoderate absorption took place. This effect was more pronounced with the use of transducers of higher frequency and smaller diameter. When a focusing lens, 25 mm focal length, was attached to the transducer surface, sound beam converged to a narrow zone, followed by later scattering. These results suggest that the transducer should be selected as to the frequency and diameter according to the site of the lesion suspected and the nature of the pathology.

6.The Influences of Arteriosclerosis on the Development and Progression of Diabetic Retinopathy .
Journal of the Korean Ophthalmological Society 1999;40(9):2514-2522
To evaluate the relationship between arteriolosclerosis and diabetic retinopathy, we graded the levels of diabetic retinopathy and arteriolosclerosis and compared each other in 255 patients with non-insulin dependent diabetes. And we also measured serum lipid levels and checked other risk fac-tors for diabetic retinopathy. SPSS was used for statistical analysis. Patients with advanced arteriolosclerosis were at higher risk of severe diabetic retinopathy. And patients with elevated plasma total cholesterol, LDL-C, TG had more severe levels of diabetic retinopathy than whose lipid levels were normal. These results suggested that advanced arteriolosclerosis and elevated serum lipid levels are associated with severe diabetic retinopathy. For preventing visual threatening complications of diabetic retinopathy, the degree of arteriolosclerosis and serum lipid levels should be carefully monitored in the evaluation of diabetic retinopathy.

7.Pituitary Stalk Transection Syndrome
Journal of Korean Society of Endocrinology 1996;11(3):324-329
We experienced one case of severe pituitary dwarfism in a 16 years old male boy that magnetic resonance image(MRI) revealed transection of the pituitary stalk with the ectopic location of posterior pituitary gland and hypoplastic anterior pituitary gland. The serum growth horrnone(GH) response to clonidine and L-dopa revealed severe GH deficiency. The patient revealed normal response in TSH, prolactin and LH, FSH to TRH and LHRH respectively. So far, the primary cause of idiopathic pituitary dwarfism in many patients was due to hypoxic injury to hypothalmus by perinatal insults. In this patients, there was no history of perinatal insults and postnatal head trauma. We report a case of severe dwarfism due to hypogenesis of anterior pituitary gland.

8.Treatment of traumatic gap in long bones
The Journal of the Korean Orthopaedic Association 1973;8(4):417-422
Recently there has been a noted increase in the incidence of traumatic bony gap in long bones due to accidents in industry, high speed traffic accidents and common gunshot accidents. There are several methods to treat traumatic bony gap such as bone graft (autogenous, homogenous and heterogenous), bone transplantation, periosteal osteogenesis and reinplantation of the extruded bone etc. The authors studied 26 patients of traumatic bony gap in the long bones which had been treated by autogenous bone grafting. The results of the clinical observation were as following; 1 The causes were shotgun accidents, vehicle accidennts and explosive accidents. 2 There was bony gap involved in 10 upper extremities and 16. lower extremities. The radius was the most common site in the upper extremity and the femur in the lower extremity. 3. The largest bony gaps were 10.5cm. in the tibia and next were 10.6cm. in ulna and 9.0cm. im humerus. 4. The period of the bony union in these cases was prolonged 1.5~3 times the usual healing period of simple fractures. 5. It was very important to prevent and control infection of the open fractures and to decide the correct time for bone grafting operation after healing of the infected wounds. We did the bone grafting sugery 2 or 3 months later after the infected wounds had been healed. 6 The authors could avoid some complications such as delayed union, shortening of the affected limbs and stiffness of the joints of the affected limbs etc.

Cutaneous horn is a clinical decription for a cohesive mass of cornified mterial protruding from the surface of the skin. The incidence of cutancous horn is relaively rare and the lesion is usually single, The predilection sites are known to be the exposed area of the skin, that is, face, ear, dorsum cf hand etc. Soles are reported as the least common site of the cutaneous horn. Here, we report two cases of cutaneous horn. The one was a 49 year old schzophrenic male who had multiple cone shaped protrusions on hoth soles for 10 year. The other was 17 year old, boy who had a single cornified protrusion on the left forhead. The histopa.thologic findings from the base of two cases were consistent with benign hyperplastic epithelium.
