This study aims at the developing of a computer program for the evaluation of nursing care quality. Since the professional nursing care requires a consistent evaluation, the computer program for the measurement of quality of nursing care is necessary. It provides the nursing care with an effective and efficient management of nursing quality. In this study, a computer program is developed as a module. The evaluation criteria are structured in a hierarchical manner. Each evaluation area includes several items, which again have their own indicators. The system consists of 7 evaluation areas, 32 evaluation items, and 71 indicators. Scoring is possible with the evaluation items. The scoring types of the program are of two types, that is, the norm-referenced type(option 1) and the criterion-referenced type(option 2). With this program, an accurate and consistent evaluation of nursing care with the rapid feedback to nursing care practice is expected.

PURPOSE: To evaluate the incidence of disc extrusion and neurologic deficit, the relation between disc extrusion and neurologic deficit and the treatment results according to our basic treatment principles in lower cervical facet joint fracture and dislocations MATERIALS AND METHODS: Twelve patients were evaluated, 8 male and 4 female with an average age of 41 years comprised the group. Six injuries were attributable to automobile accidents, 5 to fall from building, bed, floor and hill, and one to stand on her head. One case was distractive-flexion stage (DFS) 1, 9 cases with DFS 2 and 2 cases with DFS 3. Plain X-ray, CT, Myelo CT and MRI were used as a diagnostic tools. As a treatment criteria, feasibility of closed reduction, status of neuroglogic injury, and stability of injured spine were considered. Anterior cervical discectomy and fusion in accompanied disc extrusion, posterior reduction and fusion with triple wiring in unreduced dislocation, and anterior decompression and fusion in incomplete cord and root injury were selected as a basic treatment principles. RESULTS: Ten out of 12 cases (83%) showed neurologic deficits, 2 complete cord injury, 1 incomplete cord injury, and 7 radiculopathy. Nine out of 12 (75%) demonstrated disc extrusion and all disc extruded patients had neurologic deficits. Anterior cervical discectomy and fusion (ACDF) were performed in 5 cases, ACDF and posterior reduction with triple wiring (PRTW) in 4 cases, PRTW in 1 case, and skull traction and philadelphia brace in 2 cases. Seven radiculpathy patients were completely recovered and one incomplete cord injury patient can ambulate with spastic gait after surgery. There were 2 bed sore and 1 pneumonia in complications. CONCLUSION: Soft disc extrusion should be evaluated carefully with MRI and CT in lower cervical spine injury with the facet joint fracture-dislocations before the decision of treatment. As disc extrusion always accompanies neurologic deficit, it must be surgically treated by anterior cervical discectomy and fusion.

The tibial plafond fractures result from an axial compression snd rotational forces causing variable degrees of metaphyseal disruption, articular damage, and malleolar displscement. It is relatively uncommon but a most difficult fracture to manage. It has been treated in a number of manners, but the best results have been occurred when stable internal fixation is accomplished using plates and screws. Basic steps in reconstruction are restoration of anatomic length of the fibula with plate fixation, reconstruction of the tibial articular surface, cancellous bone grafting of the metaphyseal defect and buttress plating of the distal tibia. The suthor analysed the 20 cases of the tibial plafond frsctures in 17 patients, which were trested at the Department of Orthopedic Surgery, Paik Hospital, Inje Medical College from Jsnuary 1983 to March 1987. The longest durstion of followup was 2 years and 4 months and shortest one was 6 months, and the aversge was one year. The results were as follows : 1. Among the 17 patients, male were 16 and female was one. 2. The major causes of injury were a fall from a height. 3. The most frequent type of fracture was type C by Ruedi and Allgower classification. 4. Regardless of the method of trestment the type A and B were in good and fair result, but the type C were fair in 4 cases and poor in 8 cases. There were 7 cases of snkle fusion in poor group. 5. It is important to remind the basic steps in reconstruction and applied in sn individual csse especially in type C. If anatomic reconstruction of the joint surface can be restored and stable fixation achieved, esrly motion of the ankle joint is made possible. This early motion reduces stiffness of the ankle and win yeild the most sstisfying result. But the anatomic reduction of ank1 joint is difficult to be obtained in each case especially in type C and may consider an ankle fusion.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

The humerus is anatomically and phyelologically unique, such as, firstly, it is a non weight bearing bone, secondly, it has greatest range of motion, thirdly, when at rest while the person is standing, the axis of bone hangs vertically and is influenced by gravity, and conservative methods usually used in treatment. However, in the event of closed reduction failure, open fracture, multiple fracture, and old age, operative method may be employed. Authors reviewed and analzed 84 humeral shaft fractures which had been treated at the Department Orthopedic Surgery, Paik Hospital from Dec. 1979 to May 1988. The results were as follows : l. Among the 84 patients, male were 63 and female were 21. 2. The major causes of injury were a traffic accident. 3. The most frequent type and site of fracture was comminuted and middle one third. 4. The incident of radial nerve injury was 17 cases. 5. Of 84 cases, 22 cases were treated conservatively and 62 cases operatively. 6. The most common complication was non-union of 14 cases, of which 10 cases were treated with plate and bone graft and 4 cases with only bone graft.

PURPOSE: The purpose of this study was to examine the significance of increased bone density according to whether bone grafts were applied using demographic data with Cone Beam Computed Tomography (CBCT) and to compare the bone densities between before and after implant prosthesis using the Hounsfield index. MATERIALS AND METHODS: Thirty-six randomly selected computed tomography (CT) scans were used for the analysis. The same sites were evaluated digitally using the Hounsfield scale with V-Implant 2.0(TM), and the results were compared with maxillary posterior bone graft. Statistical data analysis was carried out to determine the correlation between the recorded Hounsfield unit (HU) of the bone graft and implant prosthesis using a Mann-Whitney U test and Wilcoxon Matched-pairs test. RESULTS: The bone grafted maxillary posterior teeth showed an increase in the mean values from-157 HU to 387 HU, whereas non-grafted maxillary posterior teeth showed an increase from 62 HU to 342 HU. After implantation, the grafted and non-grafted groups showed significantly higher bone density than before implantation. However, the grafted group showed significantly more changes than the non-grafted group. CONCLUSION: Bone density measurements using CBCT might provide an objective assessment of the bone quality as well as the correlation between bone density (Hounsfield scale) and bone grafts in the maxillary molar area.
