OBJECTIVES The level of benzene exposure in the petrochemical industry during regular operation has been well established, but not in turnaround (TA), where high exposure may occur. In this study, the characteristics of occupational exposure to benzene during TA in the petrochemical companies were investigated in order to determine the best management(More)
OBJECTIVES This study was designed to evaluate exposure levels of various chemicals used in wafer fabrication product lines in the semiconductor industry where work-related leukemia has occurred. METHODS The research focused on 9 representative wafer fabrication bays among a total of 25 bays in a semiconductor product line. We monitored the chemical(More)
OBJECTIVES The purpose of this study was to measure the concentration of volatile organic compound (VOC)s originated from the chemicals used and/or derived from the original parental chemicals in the photolithography processes of semiconductor manufacturing factories. METHODS A total of four photolithography processes in 4 Fabs at three different(More)
PURPOSE The aim of this study is to evaluate the subfoveal choroidal volume change in the patients with branch retinal vein occlusion before and after intravitreal anti-vascular endothelial growth factor injection using the enhanced depth imaging optical coherence tomography. METHODS We measured the bilateral subfoveal choroidal volume in 15 patients(More)
OBJECTIVE Pravastatin has been reported to elevate circulating adiponectin levels in patients with various insulin resistant state, hypertension, coronary artery disease, and hypercholesterolemia. This study aimed to evaluate whether pravastatin increase serum total and high molecular weight adiponectin levels and improve insulin sensitivity in female(More)
This study explored the health hazard of those exposed to methylene chloride by assessing its atmospheric concentration when a tear gas mixture was aerially dispersed. The concentration of methylene chloride ranged from 311.1-980.3 ppm (geometric mean, 555.8 ppm), 30 seconds after the dispersion started. However, the concentration fell rapidly to below 10(More)
