From the very knowledge of Industry 4.0, its implementation is carried out in all segments of society, but we still do not fully understand the breadth and speed of its implementation. We are currently witnessing major changes in all industries, so new business methods are emerging. There is a transformation of production systems, a new form of consumption, delivery, and transportation, all thanks to the implementation of new technological discoveries that cover robotics and automation, the internet of things (IoT), 3D printers, smart sensors, radio frequency identification (RFID), etc. Robotic technology is one of the most important technologies in Industry 4.0, so that the robot application in the automation of production processes with the support of information technology brings us to smart automation (i.e., smart factories). The changes are so deep that, from the perspective of human history, there has never been a time of greater promise or potential danger.

It is shown that locally asymptotically stable equilibria of planar cooperative or competitive maps have basin of attraction \begin{document}$ \mathcal{B} $\end{document} with relatively simple geometry: the boundary of each component of \begin{document}$ \mathcal{B} $\end{document} consists of the union of two unordered curves, and the components of \begin{document}$ \mathcal{B} $\end{document} are not comparable as sets. The boundary curves are Lipschitz if the map is of class \begin{document}$ C^1 $\end{document} . Further, if a periodic point is in \begin{document}$ \partial \mathcal{B} $\end{document} , then \begin{document}$ \partial\mathcal{B} $\end{document} is tangential to the line through the point with direction given by the eigenvector associated with the smaller characteristic value of the map at the point. Examples are given.

SuMMAry – Introduction. Ocular microvascular changes can be related to kidney deterioration in chronic kidney disease (CKd). We aimed to identify the association between retino-choroidal parameters and kidney deterioration in diabetics and non-diabetics. Methods. The study group consisted of CKd patients (cross-sectional study) with arterial hypertension with different stages of CKd. Complete eye examination was completed with optical coherence tomography angiography (OCtA) scans of the macular region. According to the value of glomerular filtration rate (gfr) and albuminuria, patients were divided into groups: low gfr (<60ml/min) and high gfr (>60ml/min) and CKd patients without albuminuria and CKd with micro or macroalbuminuria. Results. One hundred and six eyes of 106 chronic kidney disease patients were evaluated. The mean retinal thickness in gfr <60 ml/min group was 275,73±9,65 micron (µ), whereas in a gfr >60 ml/min group was 274,36±10,77 µ. OCtA showed lower deep vascular density (dvd) in CKd with albuminuria versus CKd without albuminuria group (p < 0.001). Albuminuria was inversely related to choroidal and retinal thickness measures of superficial (Svd) and dvd. Conclusions. CKd is associated with retinal diluting and decreasing kidney function with reduction of retinal and choroidal vascular density.
