Dane osobowe stanowią swoisty identyfikator osoby fizycznej. Na przestrzeni lat informacje będące dany osobowymi są stale zbierane i przetwarzane. Nieświadomość użytkowników w sieci prowadzi niejednokrotnie do kradzieży personaliów oraz wyłudzeń tożsamości. Poniżej przedstawiono sposób cyfrowego przetwarzania danych osobowych, a także anomalie społeczne, związane z kradzieżą personaliów oraz sposoby zapobiegania im w przyszłości.

Personal data is a specific identifier of a natural person. Over the years, personal information is constantly collected and processed. The article treats about method of digitally processing personal data, as well as social anomalies such as: theft of personal data or identity frauds and ways to prevent them in the future.

The article concerns the optimization of manual wheelchairs with a lever propelling system. Lever-driven manual wheelchairs are a promising wheelchair group, however they still need to be improved in order to compete successfully with classic manual push rim-driven wheelchairs. Also, despite all manual wheelchairs human work efficiency during propulsion plays an important role, there is not enough research carried out that would focus on this problem regarding lever-driven wheelchairs. The research, presented in this paper, according to the authors' intention, is to make this knowledge gap smaller. The article describes an analytical optimization method for adjusting important lever-drive system parameters - levers length and its axis of rotation position - to individual human anthropometry. The method is based on experimental data regarding maximum human push capabilities acquired in another study. The optimized parameters' values were determined after assessment of maximum human expendable energy during a single work phase (pushing the levers). As a result of this study authors determined optimal levers length and their axis of rotation position for a 50 percentile French male. The carried out research shows also, that the suboptimal area for positioning the levers axis of rotation is relatively wide.

Wykonano badania oddziaływnia cząstek: VC, TiC, NbC, Al2O3, Ti(Zn,Al)3, (Fe,Mn)3Si2A15 oraz krzemianów z frontem krystalizacji w żeliwie, stopach Fe-C-X, Zn-Al, Cu-Al i kompozycie Al-Al2O3. Badania wykazały, że węgliki są wchłaniane przez austenit w żeliwie zaś cząstki krzemianów przez grafit kulkowy. Cząstki Al2O3 są odpychane do przestrzeni międzydendrytycznych kompozytu Al-Al2O3, co jest przyczyną ich niejednorodności strukuralnej. Płaski front krystalizacji stopów Al-Cu odpycha cząstki (Fe, Mn)3Si2A15, które gromadzą na końcu wlewka.

The tests of intereaction of particles namely VC, TiC, NbC, Al2O3, Ti(Zn,Al)3, (Fe, Mn)3Si2A15 and silicates with the solidification front in cast iron, Fe-C-X as well as Cu-Al and composites in Al-Al2O3 system were made. Research proved that carbides are engulfed by austenite in cast iron while sicate particles are engulfed by nodules of graphite. Particles of Al2O3 are pushed in interdendritic spaces of Al-Al2O3 composite, what is the cause of structural inhomogenity. Flat solidification front of Al-Cu alloys push particles (Fe, Mn)3Si2A15 which are collects at the end of ingot.
