Osteoporosis, which causes mainly fracture of the spine, proximal femur and distal radius by minimal trauma, is a major public health problem and its prevalence is steadily increasing in Korea according to the development of public health care. There are reliable methods for diagnosis based on bone densitometry. Early detection and intervention are important for reducing the incidence of fractures. A consensus definition of osteoporosis, based on bone density measurement, has been developed by the World Health Organization(WHO). In this study, bone mineral density(RMD) was measured by dual energy x-ray absorptiometry(DEXA) at the proximal femur and lumbar spine in 132 post-menopausal women. The purpose of this study is to find influential factors on the BMD of the proximal femur and the lumbar spine and to analyze correlation between BMD and the problematic factors. We obtained the following results : 1. Mean BMD score, T-score and Z-score of the proximal femur were $0.81(g/cm^2)$, -2.45(S.D.) and -2.09(S.D.) respectively and in the lumbar spine were $0.83(g/cm^2)$, -2.02(S.D.), -2.43(S.D.) respectively. 2. In correlation analysis between BMD and many factors, correlation coefficients were -0.467, 0.212, -0.321 and 0.241 in age, height, duration after menopause respectively. BMI and the residuals were comparatively small. 3. Correlation coefficients to age matched BMD, in height and body weight were 0.222 and 0.241, in age and duration after menopause were -0.268, -0.282. 4. The fracture threshold of proximal femur BMD to the 90th percentile was $0.845(g/cm^2)$. 5. At the result of multiple regression analysis, age, body weight, $BMI(kg/m^2)$ and duration after menopause described as significant variables.

A clinical evaluation was performed on 545 cases of the chest trauma those had been admitted and treated at the department of thoracic and cardiovascular surgery in Chosun University Hospital during the past 11 years 5 months period from January 1978 to may 1989. Obtained results were as follows: 1. The ratio of male to female was 3.9: 1 in male predominance, and the majority[66.6%] was distributed from 3rd to 5th decade. 2. Nonpenetrating chest trauma was more common than penetrating about 4.6 times, and the most common cause of the nonpenetrating injuries was traffic accident[241/448, 53.8%] and of the penetrating injuries was stab wound[88/97, 90.7%]. 3. Only 79 cases[14.5%] were arrived to our emergency room within one hour after trauma. 4. The most common lesion due to trauma among these admitted patients was rib fracture[390/545, 71.6%], and the others were lung contusion[217/545, 39.8%], hemothorax[35%], hemopneumothorax[19.6%], and pneumothorax[11.8%] et al in decreasing order. 5. The associated injuries those required special treatment of other departments were 223 cases and its distributions were bone fractures[178/545, 32.7%], head injury[5.3%], and abdominal injury[6.6%]. 6. The others, but interesting chest injuries were follows: sternum fracture[3.1%], diaphragm rupture[2.6%], myocardial laceration and rupture[2 cases], bronchial rupture and laceration[2 cases], and traumatic thymoma rupture[1 case]. 7. The incidence of flail chest was 5.8%a[26/448] in the nonpenetrating injury, and the causes were multiple rib fracture which was in rows more than 4 rib fracture[20 cases], and sternum fracture[6 cases]. 8. We could managed the most of the patient with conservative treatment[43.1%] or closed tube thoracostomy[52.7%], but required emergency open thoracotomy in 64 cases

A two-dimensional BEM code, $FRACOD^{2D}$, was applied to simulate fracture initiation and propagation processes in a rock pillar during an in situ heater test of a rock pillar planned at the $\"{A}sp\"{o}$ Underground Rock laboratory of SKB, in Southern Sweden. To take the advantage of conventional BEM for simulating fracturing processes, but without efforts for domain integral transformation, a hybrid approach is developed to simulate the fracturing processes in rock pillar under coupled thermo-mechanical loading. The code FRACOD was used for simulating the fracture initiation and propagation processes with its boundary tractions reflecting the effects of the initial and redistributed thermomechanical stresses in the domain of interest at multiple excavation and heating steps were produced by a special algorithm of stress inversion, based on resultant thermo-mechanical stress fields at each excavation and heat loading step by a FEM code without considering fracturing processes. This hybrid approach can take the advantages of both types of numerical methods and avoids their shortcomings for fracturing process simulation and domain effects, respectively. In this paper, we present the hybrid approach for the stress, displacements, and fracturing processes at sequential excavation and heating steps of the in situ heater test as a predictive modelling, the formulation of the fracturing models and the predictive results. Two sections of borehole depth, 0.5 m and 1.5 m below the tunnel floor are considered. The pillar area is modelled with the FRACOD and the stress field produced by excavation and heating is transferred with corresponding boundary stresses. From the modelling results, the degree of fracturing and damage are evaluated for 120 days of heating. Dominated shear fracturing in the vicinity of the central pillar was observed from the models at both sections, but spalled area appears to be limited. Based on the modelling results, a sensitivity study for the effect of pre-existing fractures in the vicinity of the holes is also conducted, and the initiation and evolution of EDZ around the deposition holes are investigated using this particular numerical technique.

The Cheolam silver deposits are emplaced along the fractures in breccia dike and the Hongjesa granite. Breccia dike contains fragments of late Cretaceous acidic volcanic rocks and other fragments of various rocks distributed in the mine area. Therefore it is presumed that the mineralization was taken place in later than late Cretaceous time. Mineral paragenesis is complicated by multiple episodes of fracturing. Six distinct depositional stages can be recognized: stage I, deposition of base metal sulfides; stage II, deposition of base metal sulfides and silver minerals; stage III, deposition of carbonates; stage IV, deposition of silver minerals and base metal sulfides; stage V, deposition of silver minerals; stage VI, deposition of barren quartz. Silver minerals from the deposits are native silver, acanthite, pyrargyrite, argentian tetrahedrite, stephanite, polybasite, pearceite, allargentum, antimonial silver and electrum. Fluid inclusion studies ware carried out for stage I, II, IV and VI quartz and stage III calcite. Homogenization temperatures for each stage are as follows: stage I, from $225^{\circ}$ to $360^{\circ}C$; stage II, from $145^{\circ}$ to $220^{\circ}C$; stage III, from $175^{\circ}$ to $240^{\circ}C$; stage IV, from $130^{\circ}$ to $185^{\circ}C$; stage VI, from $120^{\circ}$ to $145^{\circ}C$. Salinities of ore fluids were in the range of 4 and 10 wt.% equivalent NaCl over stage I and stage VI. Ore mineralogical data of each stage indicate that temperatures are within the range of homogenization temperature of fluid inclusions and sulfur fugacities declined steadily from $10^{-9.7}atm$. to $10^{-18.7}atm$. through stage I into stage V.

Background: Bone fractures are high in elderly patients with type 2 diabetes mellitus (T2DM). Hyperglycemia and chronic kidney disease may increase the risk of fracture prevalence via altered bone metabolism, but whether glycemic control and kidney function are associated with the risk of fracture prevalence remains unclear. This study evaluated the relationship between glycemic control and baseline estimated glomerular filtration rate (eGFR) and risk of fracture prevalence in older and middle-aged patients with T2DM. Methods: Patients who underwent a general medical check-up between 2009 and 2013 were selected from the Korean National Health Insurance Sharing Service records. Chi-square test and multiple logistic regression analysis were used to assess the relationship between glycemic control and eGFR and risk of fracture prevalence. Results: Cumulative fracture prevalence were higher in patients with T2DM, irrespective of whether they had tight or less stringent glycemic control (fasting blood glucose [FBG] ${\geq}110mg/dL$). After adjustment for baseline age and FBG, tight and less stringent glycemic control was significantly associated with increased adjusted risk of fracture prevalence in middle-aged patients with T2DM (OR=1.13, 95% CI, 1.05-1.21, p=0.0005 vs OR=1.13, 95% CI, 1.06-1.20, p=0.0001), but not in older patients. Baseline eGFR was not significantly related to fracture prevalence in either older or middle-aged patients. Conclusion: Less stringent glycemic control significantly increased the adjusted risk of fracture prevalence in middle-aged patients with T2DM. Further studies are needed to confirm the effect of tight glycemic control on fracture prevalence.

Purpose: Hemodynamically unstable pelvic fractures represent therapeutic challenges for the trauma team. The authors of this article have studied the clinical profiles of the angiographic intervention population at the emergency department during four years (2005~2009) to develop clinical guidelines for preventing deaths due to multiple trauma and for predicting the prognosis during initial evaluation. Methods: We performed a retrospective review of 34 patients who had undergone angiographic interventions at the emergency department and compared the differences in clinical variables between survivors and non-survivors. Results: Representative values were compared between survivors and non-survivors : RTS (revised trauma score) 7.006 (6.376~7.841) vs. 6.128 (4.298~6.494), PRC (packed red cell) units 5.5 (2.0~11.0) vs. 15 (8.0~18.5), and lactate (mmol/L) 3.0 (1.0~7.0) vs. 8.5 (3.5~10.5). RTS (p<0.01) and PRC units before angiographic interventions (p=0.01) and lactate (p=0.02) had correlations to the final outcomes. Conclusion: The availability of an angiographic suite and persistent hypotension after adequate fluid resuscitation for pelvic trauma are good indications of angiographic intervention for pelvic hemorrhage.

Purpose: The open abdomen is now the standard of care in various clinical situations, especially it is used to treat abdominal compartment syndrome. Many techniques have been reported for closure after an open abdomen, but most take a long time for complete definitive closure and are associated with various problems. We describe a technique using biologic mesh that can achieve early definitive closure after an open abdomen. Methods: A 45-year-old man presented to the emergency room with a painful hip and painful lower extremities after a fall from 80 feet. Radiologic examination revealed multiple fractures of the pelvis and low extremities. Abdominal compartment syndrome caused by a retroperitoneal hematoma developed during the orthopedic surgery. We performed exploration immediately and closed abdomen temporarily. A peritoneal graft of porcine dermal collagen with anterior myofascial approximation of the rectus abdominis muscles and sliding skin flap was performed three days after the previous surgery. Results: There were no complications related to the wound. The patient was transferred to the Department of Orthopedic Surgery seven days after the initial surgery. Conclusion: Early definitive closure using porcine dermal collagen is a feasible method that can reduce the length of hospitalization and the number of operations for an open abdomen.
