Objective; Development of Prescription AI decision support system with machine learning Method; An Android based mobile application was developed to provide the user the results from the statistical model we developed. Machine learning model to predict the consumption rate of medical resources was developed with Tensorflow. Result; The solution developed for this study can provide decision support for army medical officers by providing the frequency of prescription for the diagnosis. We can predict the demand for medical supply using the machine learning algorithm developed for this study. The prediction may be helpful in saving costs and meeting supply for demand. Conclusion; The application developed for this study may be not only helpful for increasing accuracy for the management of patients but also be resourceful for the physicians, especially for the first-year army officers or general physicians.

The authors reviewed the radiographs and medical records of 134 consecutive patients who underwent chemonucleolysis and automated percutaneous lumbar discectomy(APLD) between March 1990 and December 1994 at our institute. Among the 134 consecutive patients, 90 patients underwent chemonucleolysis and the other remaining patients underwent APLD using a nucleotome. The results are summarized as follows : 1) In both groups, predomient patients were of young age and males. 2) The most common lesion was in L4-5 interspace inn both groups. 3) The posterior lateral type showed high incidence in APLD group. 4) The results were better in the younger age group and when spinal CT demonstrated posterior lateral type in both groups. 5) The results showed relatively good success rate of 84.4% in chemonucleolysis group and 88.6% in APLD group. 6) Better results can be anticipated when patients are carefully selected and operated on with a higher skillful technique.

The authors analyzed 72 cerebral stroke with diabetes mellitus who admitted to our hospital during 1989 to 1993. Pathophysiology and clinical characteristic complication and mortality was analyzed. Following are results : 1) Among 398 total cerebral stroke who were hospitalized to our hospital during 1989 to 1993. there were 72 cerebral stroke with diabetes(18%). 2) The rate of cerebral infarction and hemorrhage was 67% and 33%. The infarction rate was much higher compared with it of general cerebral stroke. 3) Various complications were presented and mortality rate was 24.2% which was regarded higher than it of general cerebral stroke. 4) Association of mortality. prognostic index and other variables were analyzed.
