It is now well-known that the electronic data processing system(EDPS: computer) is very useful for indexing, sorting, verification, and so on. And a few orthopedics in Korea are processing informations with computers for their medical records respeetively. But since there are no established principles on the description of orthopedic diseases, a computer programmer unfamiliar with medical terms is poor in electronic processing for medical records. After processing with an IBM computer for several years, it has come to our attention that we have a need for standardization of the description of orthopedic diseases for EDPS. Based largely on the International Classification of Diseases(ICD-9th), we propose the following: 1. Diseases should be written in English, and whether it be capital letter or small letter does not matter. 2. Description of the disease should be in order of title, region of the body, cause or present status, and side of the body. The sequence may be changed without problem, but only the noun form should be used. It is also recommended that the key words in articles be defined. 3. Abbreviated forms should be avoided. If inevitable, the abbreviation should be used consistently from the first to the 1ast. 4. Connection with other types of medical records such as medical insurance system by registering the code number of the International Classification of Disesaes at the end of the description or on another line.

OBJECTIVES: This study is to see the transition and pattern of the industrial iureal worker, and to develop the prediction model. METHODS: The data of the study are based on the samples from data-warehouse of Occupational Safety & Health Research Institute and are summed monthly from Jan 1986 to Dec 1999. This study data used data mart and Meta data from DW in KOSHA. The prediction model of the injured worker in Industry is designed by using a winters time series method after data preparing (i. e. sample, explore, modify) from DW. RESULTS: Thls predicted model obtained Winters-method multiplicative in exponential smoothing among applied all models, after the tlme series (total 163 months). It showed that the prediction power was 95.5 %. CONCLUSIONS: In the process of exploring the data, totally the rate of industrial injureal workers reduced, and in the yearly circulation, in February and September the number is the lowest but in June, July, October and November the higher. The number of monthly average injureal workers is 8709 (95 % confidence interval 8277, 9140). From the developed prediction model, since Aug 1999 the industrial injureal worker reduced rapidly in Dec 1999 and first period of 2000. But In second period of 2000 the number of the injured workers is increasing. To conclude, as the total economic situation is becoming better in 2000 than In 1999, its is supposed that the injured workers will increase more than the predictive injured workers because of the increase of production rate and labor force.

A histological and electron microscopic study were conducted in order to observe a morphological changing pattern of patellar ligament autograft after endoscopic ACL reconstruction. Seventeen patients among 117 consecutive series which underwent endoscopic ACL reconstruction from January 1990 to March 1995, were involved in this study according to the various follow-up periods. In second-look arthroscopic finding at 6 months follow-up after ACL reconstruction, reconstructed ACL was covered with synovium and round-shaped, and after the biopsy active bleeding could be seen. In histological study, 6 months follow-up, spindle or ovoid shaped fibroblast with hypercellularity, high crmp patterns of collagen fiber, and parallel arrangement of fibroblast to collagen fiber were noted. The cellularity of fibroblast decreased in according to periods of follow up. At 12 months follow up, spindle or ovoid fibroblast, its cellularity and arrangement pattern and crimp pattern of collagen fiber seemed to be almost similar to those of normal ACL. This similaryity continued up to 2 years and 2 months after reconstruction. In EM study, until 6 months follow-up after reconstruction, the graft showed randomly arranged fibroblasts with hypercellularity, which had abundant cytoplasm with marked irregular cytoplasmic borders and prominent nuclear indentation, Collagen fibrils were immature and showed a unimodel distribution with small diameter. At 12 months follow-up, elongated fibroblasts appeared, but these cells contained folded nuclei and abundant cytoplasm. Collagen fibrils had parallel arrangement and sparse cross striation, and comprised of mainly small fibrils and scattered large fibrils. After 24 months follow-up, the cellularity decreased more. The regular arrangement of collagen fibrils with wavy pattern similar to normal anterior cruciate ligament was noted. Two distinctive population of the small and large diameter of fibrils was also observed (bimodal distribution). At 26 months, the large and small collagen fibrils compresed a characteric bimodal pattern with parallel arrangement, but the majority of fibroblasts had irregular cytoplasmic contour, and abundant cytoplasm with increased organelles, which indicated the active function. These findings suggest that the graft are still immature even at 26 months in postoperative follow up despite considerable maturation of collagen fibril.

The purpose of this research is to analyze the effects of aerobic exercise on body composition, cardiopulmonary function, serum lipid level and antioxidants of obese and normal college female students. The subject group was made up of 13 normal students (below 30% body fat ratio ) and 12 obese students(above 30% body fat ratio). After a pretest, the subjects were given an 8-week aerobic program. Then the subjects were given a posttest and analyzed of body composition, serum lipid level, antioxidants and cardiopulmonary function after the 6th and the 8th week of the program, The program schedule was made up of 4 days per week, 60 minutes per day. Test includes B. W., subscapular and triceps subcutaneous fat thickness. change of respiratory gas, and two blood sampling before treadmill exercise and post all out state, which analyzed serum lipid and antioxidants. The subjects performed treadmill exercise starting with 4km/hr of walking and then gradually increase the speed of 1km/hr per minute until all out state. The obtained data were analyzed using SAS program. The statistical methods employed here were one-say ANOVA with repeated measure, Duncan Multiple range test, paired-t test and t-test. The test results and conclusion go this research were as follows. 1. The effects of aerobic exercise on body composition were as follows ; Percent body fat was significantly reduced 6 weeks after the program and lean body mass was significantly increased 8 weeks after the program in both groups(obese group : F=3.44 P=.044, normal group: F=3.30 P=.048). subscapular skinfold of the obese group showed a remarkable decrease after the 6th week(F=4.3 P=.21) triceps skinfold of the normal group showed a remarkable decrease after the 6th and 8th week(F=4.55 P=.017) compared with readings before the aerobic program, the aerobic program made a bigger difference concerning body fat, lean body mass, subscapular skinfold in the obese group than in the normal group(t=2.41 P=.024 p=.025, t=2.43 p=.028). 2. The effects of aerobic exercise on cardiopulmonary function were as follows : Maximal O2 uptake/kg was significantly increased 6 weeks after the program in the obese group(F=3.20 P=.054), but not much difference was observed in the normal group. maximal pulse rate was significantly reduced in both groups after 6 weeks of the program(obese group : F=2.77 P=.087, normal group : F=7.17 P=.001). 3. The effects o aerobic exercise on serum lipid level were as follows : In a resting period, total cholesterol, Triglyceride, and LDL-cholesterol were slightly higher in the obese group than in the normal group, but HDL-cholesterol was higher in the normal group. But with the aerobic program, total-cholesterol, Triglyceride, LDL-cholesterol were reduced gradually and HDL-cholesterol got increased in both groups, but not much change was noticed in the normal group. However, in the obese group, serum HDL-cholesterol level got increased significantly(F=5.12 P=.012). 4. The effects of aerobic exercise in serum antioxidants were as follows ; In a resting period, the obese group's serum Free Radical and GSSG content were higher than the normal group's and the normal group's serum GSH content was higher than the obese group's. After 6 weeks of the aerobic program, Free Radical was reduced significantly in both groups(obese group : F=13.87 P=.000, normal group: F=18.60 P=.000) In the obese group, 8weeks after the program, GSH was increased significantly(F+13.78, P=.000). In the normal group, 6 weeks after the program GSH was reduced but increased again after 8 weeks(F=6.07 P=.005). Plasma GSSG was significantly increased after 8 weeks of exercise in both groups(obese group: F=19.75 P=.000, normal group: F=2.42 P=.000). Compared with readings before the aerobic program, the aerobic program made a bigger difference serum GSH in the normal group than in the obese group(t=3.37 p=.003) As this results shows, It is known that the regular aerobic exercise improves cardiopulmonary function, body composition, serum lipid effectively and through the serum Free Radical reduction and antioxidant system activation, oxidant stress was suppressed. This effect was high in the obese group than in the normal one. At least 6 weeks exercise period need for improvement of body composition, cardiopulmonary function and activation of antioxidant system, This result suggest that improvement of serum lipid profile was needed longer than 8 weeks exercise period.

We have examined the regenerative capabilities of the human scalp hair follicle after grafting the lower half of the follicle. Twenty-eight of 32 intact whole-hair follicles isolated from the human scalp regenerated hairs when grafted onto the forehead of the same person. Seven of the 15 lower-half follicles regenerated complete hair follicles 8 months after grafting showed that the lower-half follicle implant reconstituted the complete hair follicle. The sebaceous gland was not regenerated, but there was an outgrowth in the sebaceous gland regPark ion. Some grafts formed epithelial cysts. Two years after grafting, the histological examination of the regenerated follicle from the lower-half implant showed that the sebaceous gland was completely regenerated. While an intact follicle shows prominent naked shaft outgPark Park Parkrowth, the sheath grows concomitantly with the shaft in lower-half follicles in culture. If grafted lower-half follicles were located too deep, the regrown sheath could not reach the epidermal layer. In this situation, the formation of an epidermal cyst was likely.

The purpose of this study was to investigate the possibility of distraction osteogenesis in membranous onlay bone graft on the mandible and to clarify the histology of bone repair during distraction osteogenesis in the membranous onlay bone in a dog model. Four dogs, 5 months of age at the beginning of the experiment, were used for this study. The zygomatic arch was exposed in the subperiosteal plane and the full-thickness zygomatic arch was harvested to 3 centimeters in length. The lateral surface of the mandibular body was exposed in the subperiosteal plane and the membranous onlay bone graft was performed with firm contact using screws. The osteotomy on the membranous onlay bone graft and underlying mandibular body was carried down week 1 in dog 1, week 2 in dog 2, week 3 in dog 3, and week 4 in dog 4 after membranous onlay bone graft. The external distraction device was applied to the mandibular body. Mandibular distraction was started 7 days after the operation at a rate of 1mm per day for a total of 10 mm distraction over 10 days. After completion of distraction, the distraction device was left in place for 6 weeks bony consolidation of the distracted area. Radiographs were carried out at 2 weeks, 4 weeks and 6 weeks after distraction. New bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between segments of membranous onlay bone graft was not generated in dog 1, but it was generated in dogs 2, 3 and 4. However, in dog 2 and 3, the new bone between segments of the distracted membranous onlay bone graft presented less firmness with fibrous tissue than that of the native underlying mandibular segment. Histologically, the distracted gap between segments of the membranous onlay bone graft was composed of much fibrous tissue in the central zone while activated osteoblastic cells formed new bone in the margins of the distracted gap in dogs 2 and 3. In dog 4, there were abundant osteoblastic activities in the distracted gap and the new bone appeared as nearly-normal cortical bone. In conclusion, these findings suggested that membranous onlay bone graft had an osteogenic capacity and that distraction osteogenesis was possible in membranous onlay bone graft.

We retrospectively evaluated the 130 low vision patients on the basis of medical recordings. Men(58.5%) were more than women. The patients in teen-age(11-20yr) were most common(23.9%). Etiologies were aphakia due to congenital cataract(21.5%), macular degeneration(15.4%), and optic atrophy(13.8%) in that order. Low vision aids were prescribed for rehabilitation of the low vision. High-power plus glasses(25.4%), magnifiers(24.6%), and telemicroscope(7.9%) were low vision aids commonly prescribed for near vision, while hand-held telescope(23.8%) was the most popular for distance vision aids. High-power plus glasses were actually worn by 31 of 32 patients prescribed for them.

A 38 year old woman presented with two week history of cough, progressive dyspnea, orthopnea and pedal edema. She had previously been in excellent health with the exception of surgery five years ago for tumor of the right thigh. The histopatihologic diagnosis was chondrosarcoma. Her clinical course was characterized by rapid aggrevation of dyspnea and eddema unresponsive to conventional managements for congestiove heart failure. Transesophageal echocardiogram showed dleft atrial mass growing from pulmonic vein. To our knowledge, cardiac metastasis from chondrosarcoma is rare and we report this is the first case of chondrosarcoma metastatic to the heart in Korea.
