The aim of this study was the quality of service evaluation of two different organizational ways in delivering infant vaccination according to a Regional Vaccination Plan. Eleven vaccination centres were selected in two Local Health Units (ASLs) belonging to the Regional Health Service of the Lazio Region, Italy. The services offering paediatric vaccinations for children under three years of ag...

The effects of various packaging systems, vacuum packaging (VACP), medium oxygen-modified atmosphere packaging (50% O2/20% CO2/30% N2, MOMAP), MOMAP combined with vacuum skin packaging (VSP-MOMAP), high oxygen-MAP (80% O2/20% CO2/0% N2, HOMAP), and HOMAP combined with VSP (VSP-HOMAP), on the activity of antioxidant enzyme, and oxidation and color stabilities in sliced Hanwoo (Korean cattle) bee...

The assessment of mental overload is essential as has been proved to be a critical cause many accidents. Mental affected by various performance shaping factors (PSFs), and harsh PSFs will either increase the task demand or decrease threshold, which rarely considered in current method. This research proposes VACP-based model considers effects PSFs. In VACP model, can identified when sum values e...

Z. Naturforsch. 55 b, 459—461 (2000); received February 21, 2000 Biomineralization, Silica, Silicon-Accumulating Plants A series of silicon-accumulating plants [different Equisetum (horse tail) species, Echium vulgare, and Symphytum officinale] were studied by solid-state 29Si NMR experiments. For this purpose, selected parts of these plants were freeze-dried and then investigated by solid-stat...

The compositions of humic acids (HAs) isolated from cultivated and forested "Terra Preta de Indio" or Amazonian Dark Earth soils (anthropogenic soils) were compared with those from adjacent non-anthropogenic soils (control soils) using elemental and thermogravimetric analyses, and a variety of solid-state nuclear magnetic resonance techniques. The thermogravimetric index, which indicates the mo...

The author of this report provides an overview of mental workload theory and mental workload measurement. She also describes the development, application, and validation of the mental workload modeling tools developed by the Human Research and Engineering Directorate of the U.S. Army Research Laboratory (ARL). These ARL tools, VACP (visual, auditory, cognitive, psychomotor) option in the improv...
