Introduction. The aim of this work was to provide a characteristics of the judo combat and present factors that may influence the result of a sports combat. On the basis of the tournament's result analysis, the combat specifics of the world's top athletes were determined and may be used to orient and streamline a training process. Material and methods. The study materials were the combat lists from the men's judo tournament in Beijing as published on the official website of the Olympic Games. The indirect observation method was applied, using computerised and available information concerning each combat. Basic statistical methods were used to process the data: arithmetic means and percentage compilation. Results. During the men's tournament, there was a total of 303 combats in all 7 weight categories. Altogether, there were 228 competitors participating. No country gained a clear advantage in the medal classification. A significant part of combats (66.67%) ended by nage-waza (throwing), of which the te-waza (hand) (27.06%) and ashi-waza (foot and leg) (23.43%) techniques most often decided about the victory. The katame-waza (grappling) techniques ended 15.51% of all combats. Out of all 47 combats that ended in a horizontal position, 37 ended by osaekomi-waza (holding). Conclusions. 1. Most combats of the men's tournament ended before time and the score awarded most often by referees was ippon. 2. The victories were most often awarded in consequence of the nage-waza (throwing) techniques rather than the katame-waza (grappling) techniques. 3. The te-waza (hand) throwing group techniques proved to be dominating.

The paper presents the results of the analysis of memristive properties observed in (Ti,Cu)-oxide thin film with gradient distribution of elements, prepared using the multi-source reactive magnetron co-sputtering process. The performed electrical measurements showed the presence of pinched hysteresis loops in the voltage-current plane for direct and alternating current bipolar periodic signal stimulation. Investigations performed using a transmission electron microscope equipped with an energy dispersive spectrometer showed that the elemental composition at the cross section of the thin film was very well correlated with the gradient V-shaped profile of the powering of the magnetron source equipped with a Cu target. The prepared samples were transparent in the visible part of optical radiation. The obtained results showed that the prepared gradient (Ti,Cu)O x thin film could be an interesting alternative to the conventional multilayer stack construction of memristive devices, which makes them a promising material for manufacturing transparent memory devices for transparent electronics.
