OBJECTIVES To study the rates of catheter associated urinary tract infection (CAUTI), Ventilator-associated pneumonia (VAP), Central venous catheter blood stream infection (CVCBSI) and surgical site infection (SSI) in Thai hospitals. The rates of the infections will be used as quality indicators. MATERIAL AND METHOD Active surveillance in 38 hospitals in Thailand during 2003-2004. Risk strati...

Serum fatty acids are increasingly used in cross-sectional surveys and cohort studies as biomarkers of dietary fat intake; however, it is currently difficult to judge whether an individual has low or high fatty acid status, or whether the distribution of fatty acids of a group of people is low or high due to a lack of appropriate reference values. In the absence of interpretive criteria, the di...

OBJECTIVES To evaluate the effect of weight percentile on deep neck infections in children. METHODS A retrospective evaluation of 79 patients who were treated for deep neck infections. The patients were divided into six groups according to weight percentile. Patients who had systemic and/or congenital disease were excluded. Their demographics, etiology, localization, laboratory, and treatment...

Wireless sensor networks enable various future applications of pervasive computing. A necessary component for building such applications is the ability to detect locations and use the user-context information in an effective way. We present MoteTrack, an indoor locating system for sensor networks. Based on RF signal strength, MoteTrack uses a two-phase approach to infer locations via a pre-comp...

Abstract We develop a dynamic model of corporate investment and financing, in which shocks to the value collateralizable assets generate variation firms’ debt capacity. show that degree similarity among financial flexibility forecasts cross-sectional return correlation. test implications with firm-level data two empirical analyses using i) an instrumental variable approach based on ii) outbreak...

The purpose of this study is to find the percentiles of fuzzy numbersand to demonstrate their applications, which include finding weightedmeans, dispersion indices, and the percentile intervals of fuzzy numbers. Thecrisp approximations of fuzzy numbers introduced in this paper are new andinteresting for the comparison of fuzzy environments, such as a variety of economic,financial, and engineeri...
