Many parallelization techniques have been proposed to enhance the performance of the Apriori-like frequent itemset mining algorithms. Characterized by both map and reduce functions, MapReduce has emerged and excels in the mining of datasets of terabyte scale or larger in either homogeneous or heterogeneous clusters. Minimizing the scheduling overhead of(More)
BACKGROUND AND OBJECTIVES In the 2002 dengue outbreak in Taiwan, some fatal cases had the underlying disease of renal failure (RF). Physicians faced difficulty in diagnosis and treatment of these patients; however, the impacts of RF on the clinical presentations and outcomes of dengue infection have not been reported previously. DESIGN, SETTING,(More)
BACKGROUND Chronic kidney disease (CKD) and hepatitis C virus (HCV) infection are closely linked and both increase patient mortality. The association of HCV and risk of developing end-stage renal disease (ESRD) has not been analyzed with competing risk model. METHOD We enrolled a prospective cohort of 4,185 patients (mean age, 62 years; 41% female)(More)
BACKGROUND Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections may lead to nephropathy. However, the association between different types of viral hepatitis and chronic kidney disease (CKD) is not well established. STUDY DESIGN Cross-sectional study. SETTING & PARTICIPANTS A large-scale community study with 54,966 adults in a Taiwanese county(More)
BACKGROUND AND OBJECTIVES The risk factors for CKD in different age groups remain unknown. This community-based study aimed to identify the risk factors for CKD in elderly and nonelderly patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A multistage sampling survey for CKD was conducted in 2007 in Kaohsiung County, an area with the highest(More)
Sequential pattern mining is a challenging issue because of the high complexity of temporal pattern discovering from numerous sequences. Current mining approaches either require frequent database scanning or the generation of several intermediate databases. As databases may fit into the ever-increasing main memory, efficient memory based discovery of(More)
BACKGROUND AND OBJECTIVES Increased arterial stiffness was reported to be associated with decreased estimated GFR (eGFR). Previous studies suggested that arterial stiffness might play a role in renal function progression in patients with chronic kidney disease (CKD). The aim of this study was to investigate whether there was an independent association(More)
BACKGROUND The pathophysiological mechanisms of renal function progression in chronic kidney disease (CKD) have still not been completely explored. In addition to well-known traditional risk factors, non-traditional risk factors, such as endothelial dysfunction, have gradually attracted physicians' attention. Angiopoietin-2 (Ang-2) impairs endothelial(More)
