Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

A review of diffraction phenomena for double slit and regularly triangular aperture has been done. First, as a width b and a space d of double slit vary, a diffraction pattern has been calculated by theory. Second, an intensity of diffraction light and separation between fringes for slit has been measured. And, we can expect that the calculated diffraction pattern for a regularly triangular aperture has three symmetric axes.

The fatigue characteristics of alumina-glass composites were evaluated by biaxial flexure test under the dynamic loading conditions. 88 specimens were tested by tested by testing 22 samples at each of four loading rates : 0.01, 0.1, 1, and mm/min. A Vickers-produced indentation crack was made at the center of the tensile surface with load of 49.0 N, and the microstructural aspects of crack propagation was investigated under statically loaded state in distilled water at 37℃. The results obtained were summarized as follows; 1. The fatigue parameter of alumina-glass composite containing 6 mol % yttria was n=22.2, σf0=319.6 MPa. 2. 10-year failure stress of alumina-glass composite containing 6 mol% yttria was 171.7 MPa. 3. Fracture surface of alumina-glass composite indicated the frictional interlocking of jogs having the tendency of toughening by crack deflection, rather than by crack bridging.

The Tailor Welded Blanks(TWB) are using various materials (different thickness, strength and different materials) can be welded together prior to the forming process. Therefore, TWB applications have become little by little important in automobile industries, because it has more light weight and process reduction. A burnish area is very important for TWB using laser welding. In this paper, evaluated failure criterion, effect of clearance and distance of between pad and punch by computer simulation. We used element separation method for fracture. And applied a plastic strain to failure criterion. According to the analysis results, we obtain failure criterion, when plastic strain is 2.0. The burnish area and clearance were inverse proportional.
