Metabolic syndrome in carbon disulfide-poisoned subjects in Korea: does chemical poisoning induce metabolic syndrome?

Objective: Mass carbon disulfide (CS(2)) poisoning was reported at a viscose rayon factory in Korea. We evaluated the association between CS(2) poisoning and the prevalence of metabolic syndrome.

Methods: The cases (n = 170) involved CS(2)-poisoned subjects, who participated in a health examination conducted at a hospital in Korea in 2005.

Angle-tuned, evanescently-decoupled reflector for high-efficiency red light-emitting diode.

We propose and demonstrate evanescently-decoupled, solid-angle-optimized distributed Bragg reflectors (DBRs) for AlGaInP light-emitting diodes (LEDs). The thickness of each DBR layer is tuned to the wavelength slightly longer than the emission peak of the active medium in order to maximize the radiated power integrated over the top surface. In addition, to increase the horizontal radiation through the side facets, the glancing-angle reflectivity at the AlInP/AlAs interface is improved by employing an AlAs layer thicker than the attenuation length of the evanescent field.
