Atypical fractures have been reported as a complication of long-standing bisphosphonate therapy and occur commonly in the subtrochanteric region or shaft of the femur showing typical radiographic features. We encountered a case of atypical fracture of the proximal one-third of the shaft of the ulna. Radiographic findings of this case differed from previously reported cases of ulnar fracture in terms of showing a transverse fracture line with cortical thickening and an oblique fracture line with anterior cortical spike. On the other hand, these findings were similar to radiographic features of atypical femoral fractures. The present case was managed surgically and union of fracture was achieved after 6 months. As there are possibilities of occurrence of atypical fractures in sites other than the femur, the physicians should cautiously examine the patients’ history and radiographic findings.

There are opinions that microalbuminuria acts as an independent risk factor for cardiovascular diseases, related to other risk factors such as endothelial cell dysfunction, hypertension, insulin resistance, obesity, hyperlipidemia and platelet aggregation dysfunction in diabetic and non-diabetic patients. We examined the prevalence of microalbuminuria and macroalbuminuria and the relationship of microalburninuria and macroalbuminuria to coronary heart. disease in type 2 diabetic patients. Out of 798 t 2 diabetic patients who were hospitalized at Yonsei medical center from Oct. 1997 to Feb. 1999, we studied 181 patients who had normal renal function and were examined 24 hour urine albumin excretion. According to the amount of urine albumin excretion, 181 patients were categorized into three groups; normoalbuminuria(less than 30mg/24hour), microalbuminuria(30-300mg/24hour) and macroalbuminxia (more than 300mg/24hour). Patients were tested using treadmill test, stress thallium scan, echocardiography, and coronary angiography for the evaluation of coronary heart disease. The freguency of normoalburninuria, microalbuminuria, and macroalbuminuria in our patients were 50.3%(91/181), 30.9%(56/181), and 18.3%(34/181), respectively. In each group, the prevalence of hypertension were 42.5%, 78.5%, and 82.3%, respectively and the prevalence of cardiovascular disease were 24.7%, 50.0%, and 46.0%, respectively. Microalbuminuria and macroalbuminuria groups showed statistically significant differences in the prevalence of hypertension and coronary heart disease compared with normoalbuminmia group(p$lt;0.05). In addition, the prevalence of diabetic retinopathy were 37.3%, 58.9%, and 55.8%, respectively and microalbuminuria and macroalbuminuria groups showed statistically significant differences in the prevalence of diabetic retinopathy compared with normoalbuminuria group(p$lt;0.05). We conclude that microalbuminuria and macroalbuminuria is a strong predictor of coronary heart disease in patients with type 2 diabetes.

본 과제에서는 참여기업인 두산인프라코어(구 대우종합기계)에서 양산중인 국산디젤엔진을 개조해 가스엔진을 제작하였으며, 두산인프라코어에서 500시간 내구시험을 2차례 실시하였고, 주관기관인 한국기계연구원에서 국산 ECU를 활용하여 도시가스를 연료로 실험을 수행한 후 김포매립지에서 현장 적용실험을 수행하였다. 메탄농도가 46sim56%로 변하는 조건에서 350kW의 출력을 달성하였으며, 삼원촉매를 적용한 결과 2005년 배기규제를 만족하는 결과를 도출하였다. 위탁기관인 전남대에서는 촉매 특성에 관한 실험을 1차년도와 2차년도에 수행하였다. 본 과제에서 개발한 LFG(=매립지가스) 엔진은 국내에서 개발된 최초의 LFG 엔진으로서 쓰레기 매립지 뿐만 아니라 음식물 쓰레기 혐기소화 처리과정, 분뇨나 축분 등의 혐기소화 처리과정, 하수종말 처리장 등에서 발생하는 바이오가스를 이용한 발전 동력원으로 사용될 수 있을 것으로 기대된다.
