New ceramic fibers, currently in various stages of commercial development, have been consolidated in intermetallic matrices such as γ-TiAl and FeAl. Fiber types include SiC, TiB2 and polycrystalline and single crystal Al2O3. This work required the development of techniques to characterize the thermochemical stability of these fibers in different matrices.SEM/EDS elemental mapping was used for this work. To obtain qualitative compositional/spatial information, the best realistically achievable counting statistics were required. We established that 128 × 128 maps, acquired with a 20 KeV accelerating voltage, 3 sec. live time per pixel (total mapping time, 18 h) and with beam current adjusted to give 30% dead time, provided adequate image quality at a magnification of 800X. The maps were acquired, with backgrounds subtracted, using a Noran TN 5500 EDS system. The images and maps were transferred to a Macintosh and converted into TIFF files using either TIFF Maker, or TNtolMAGE, a Microsoft QuickBASIC program developed at the Science Center. From TIFF files, images and maps were opened in either NIH Image or Adobe Photoshop for processing and analysis and printed from Microsoft Powerpoint on a Kodak XL7700 dye transfer image printer.

Influenza vaccination is the most effective way of influenza prevention. The vaccination rate is low worldwide. In Hungary, the vaccine is free of charge to health care workers and, therefore, the low vaccination rate is unaccountable. Aims: In this study, the authors wanted to explore those factors which influence the refusal of vaccination. Methods: The Health Science Center of Debrecen University has about 4000 employees. The authors adjusted a questionnaire with 45 questions and sent it to 525 randomly selected health care workers, 294 of whom responded (response rate, 56%). The Epiinfo software was used for statistical evaluation. Results: The respondents strongly agreed that the vaccine is free and easy to obtain at the workplace. Official recommendations of the occupational health, the Medical Association of Hungary and advice of the family doctors failed to influence the decision. However, a significant impact of communication with family members, friends and colleagues on the decision was documented. Conclusions: The results indicate that the most important tool in decision making of influenza vaccination is the internal communication, but this effect is not a permanent one. International data show highly variable vaccination rates (between 2.1% and 82%). A better vaccination rate (98% or above) may be achieved with a mandatory influenza vaccination program among health care workers. Orv. Hetil., 2012, 153, 505–513.
