Ninetyone neurotic outpatients were studied for their somatic symptom complaints. The results were as follows; 1) The frequent somatic symptoms were those of head including headache (59.3%), cardiovasular and respiratory symptoms (40.6%), sleep disturbance (38.5%), and gastrointestinal symptoms (27.5%). 2) Relatively rare symptoms were those of urogenital system (6.6%), and dermatologic symptoms (4.4%). 3) The mean number of somatic symptoms was 3.1 and that of mental symptoms was 1.1. 4) Nearly half of the patients (47.3%) complained somatic symptoms only. 5) The group of patients who complained of somatic symptoms only was significantly lower in educational level and older in age than the group of patients who complained both somatic symptoms and mental symptoms (p<0.05).
The purpose of this work is to investigate the effects of Mo content after cold rolling on the mechanical properties and recrystallization in Zr alloys. Based on the results of prior research work, Zr-1Nb-0.5Sn-xMo-0.1Fe was selected. The alloys were cold rolled with 50% reduction ratio. These alloys were recrystallized, after microstructure, mechanical properties and texture were evaluated. With increasing Mo content, Kearns number and the elongation decreased, but tensile strength increased. Also, with increasing Mo content, recrystallization temperature was retarded and grain size was refined. These facts were due to the effect of precipitation, solid solution of Molybdenum.
Primary indication for total hip arthoplasty is pain in the hip joint. The number of total hip arthroplasty has been continuously increasing and the technique and knowledge has developed quite a lot. The authors reviewed and analyzed 137 cases of primary total hip arthroplasty in 129 patients. which were performed at the Department of Orthopaedic Surgery of Dankook University Hospital from June 1994 through August 1997. The patient were 107 males and 22 females, and mean age was 54.5 years. The etiologies for diseases were 103 avascular necrosis of the femoral head. 8 primary and 12 secondary osteoarthritis, and 14 others. Functional evaluation was made with a Harris hip scoring system. The results showed an improvement in hip function from preoperative 54 points in average to postoperative 1 year 94 points in average, and satisfactory results were obtained in 88%.
