In the fi rst part of this manuscript, two OLED devices composed of Alq 3 :DCM–TPA organic material as doped emitting layer, have been simulated. In the fi rst device, the reduced mobility property of this doped layer and in the second device, trapping eff ects of this dopant are considered. With comparison of the simulation results obtained for these devices, theapproximated values of the traps concentration and Gaussian width of traps is obtained. In the second part, the OLED devices with considering of the NPB:Alq 3 organic material as mixed host emitting layer have been simulated for obtaining optimal thickness of the emitting layer. In the fi nal part, an OLED device composed of (NPB:Alq 3 ):DCM–TPA organic material as mixed host-doped emitting layer has been simulated for studying the infl uence of DCM–TPA dopant on the performance of this device.

Background: Scientometrics is a useful method for management of financial and human resources and has been applied many times in medical sciences during recent years. The aim of this study was to investigate the status of science production by Iranian scientists in the gastric cancer field based on the Medline database. Materials and Methods: In this descriptive-cross sectional study Iranian science production concerning gastric cancer during 2000-2011 was investigated based on Medline. After two stages of searching, 121 articles were found, then we reviewed publication date, authors names, journal title, impact factor (IF), and cooperation coefficient between researchers. SPSS.19 was used for statistical analysis. Results: There was a significant increase in published articles about gastric cancer by Iranian researchers in Medline database during 2006-2011. Mean cooperation coefficient between researchers was $6.14{\pm}3.29$ person per article. Articles of this field were published in 19 countries and 56 journals. Those basex in Thailand, England, and America had the most published Iranian articles. Tehran University of Medical Sciences and Mohammadreza Zali had the most outstanding role in publishing scientific articles. Conclusions: According to results of this study, improving cooperation of researchers in conducting research and scientometric studies about other fields may have an important role in increasing both quality and quantity of published studies.
