BACKGROUND We evaluated the effectiveness of a policy allowing for the sale of over-the-counter drugs outside of pharmacies by examining its effect on number of monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. METHOD We used medical claims data extracted from the Korean National Health Insurance Cohort Database from 2009 to 2013. The Korean National H...

[1] There is an established evidence of climatic teleconnection between El Niño– Southern Oscillation (ENSO) and Indian summer monsoon rainfall (ISMR) during June through September. Against the long-recognized negative correlation between ISMR and ENSO, unusual experiences of some recent years motivate the search for some other causal climatic variable, influencing the rainfall over the Indian ...

The main objective of Present study is based on meteorological variables to estimate monthly Global Solar Radiation (GSR) on a horizontal surface. Monthly mean of maximum air temperature, relative humidity, sunshine hours and wind speed values between 1974 and 2008 for Tehran city in Iran (35_41N, 51_19E), are used in this study. In order to investigate the effect of each meteorological variabl...

[1] We develop a daily-resolved global emission inventory for biomass burning using AVHRR satellite observations of fire activity corrected for data gaps and scan angle biases. We implemented this inventory in a global three-dimensional model (GEOSCHEM) to simulate aircraft CO observations during the TRACE-P mission over the NW Pacific in February–April 2001. Seasonal biomass burning in SE Asia...

A problem in biosurveillance is how frequently to update controlled vocabularies that identify various data elements such as laboratory tests and over-the-counter healthcare products. More frequent updates improve completeness of data captured over time, but introduction of new codes into a surveillance system may cause false alarms when codes are aggregated into analytic categories. We studied...
