Masqueraders who impersonate other users pose serious threat to computer security. Unfortunately, firewalls or misuse-based intrusion detection systems are generally ineffective in detecting masquerades. Although anomaly detection techniques have long been considered as an effective approach to complement misuse detection techniques, they are not widely(More)
Since computed tomography (CT) was developed and its resolution, sensitivity, and scan speed rapidly improved, the use of CT in the diagnosis of hepatic disease has been evaluated by various investigators. [1] In particular, liver-specific X-ray CT imaging has attracted much attention in cancer diagnosis and cancer treatment because liver metastases are a(More)
Systemic transplantation of adipose-derived stem cells (ASCs) is emerging as a novel therapeutic option for functional recovery of diverse damaged tissues. This study investigated the effects of systemic transplantation of human ASCs (hASCs) on bone repair. We found that hASCs secrete various bone cell-activating factors, including hepatocyte growth factor(More)
PURPOSE Coexistence of different classes of beta-lactamases in a single bacterial isolate may pose diagnostic and therapeutic challenges. We investigated a spread of Klebsiella pneumoniae isolates co-producing an AmpC beta-lactamase and an extended-spectrum beta-lactamase (ESBL) in a university hospital. MATERIALS AND METHODS Over a three-month period, a(More)
PURPOSE Luminal-type breast cancer has a good prognosis compared to other types, such as human epidermal growth factor receptor 2 and triple negative types. Luminal-type breast cancer is classified into luminal A and B, according to the proliferation index. We investigated the clinicopathological factors that affect the prognosis of the luminal-type(More)
Frequency of attacks on web services and resulting damage continue to grow as web services become popular. Unfortunately, existing signature-based intrusion detection techniques are inadequate in providing reasonable degree of web security. Web attacks are diverse in nature, and typical web architecture consists of complex and hierarchically organized(More)
BACKGROUND We evaluated the combined use of the modified Hodge test (MHT) and carbapenemase inhibition test (CIT) using phenylboronic acid (PBA) and EDTA to detect carbapenemase-producing Enterobacteriaceae (CPE) and metallo-β-lactamase (MBL)-producing Pseudomonas spp. METHODS A total of 49 isolates of CPE (15 Klebsiella pneumoniae carbapenemase [KPC], 5(More)
BACKGROUND We evaluated the analytical and clinical performances of the SD BIOLINE Rota/Adeno Rapid kit (SD Rota/Adeno Rapid; Standard Diagnostics, Inc., Korea), an immunochromatographic assay (ICA), for the simultaneous detection of rotaviruses and adenoviruses in human stool samples. METHODS We tested 400 clinical stool samples from patients with acute(More)
Free light chains (FLCs) are useful biomarkers for the diagnosis and monitoring of various plasma cell dyscrasias. One hundred fifty-seven samples from 120 patients for screening or monitoring of monoclonal gammopathy (MG) were included. The new N Latex FLC assays (Siemens Healthcare Diagnostics GmbH, Germany) were compared with the Freelite FLC assays (The(More)
