Abstract: The distance learning system and method provide distance learning efficiently and effectively. The distance learning system (DLS) includes an education program, and an education center server of an educational platform for database management, data transfers and communications amongst the education system users. The DLS divides the education program into several education levels, and students register and receive an electronic data carrier in the form of CD or DVD disk containing educational material for the subject studied. The DLS establishes an interactive on-line session of electronic workshops and the students, who do not login to the educational platform before the start of the electronic workshops are directed into a “waiting room” and later included in the electronic workshops, preferably prior to the commencement of a next part of the workshops. The “waiting room” for delayed students may be created by parallel, shifted in time running of several similar electronic workshops.

Abstract: A hexagonal paving panel, the sides of which are alternately provided with upper and lower connecting elements in the form of tab or overlap elements (102, 103) and fixing pins. The panel (100) is provided with a central aperture (109) and with a downwardly extending collar (101) on its periphery. The central aperture serves as a drain hole, stabilizes the panel on a ground and improves storage of the panels in a stack. The bottom surface (114) of the panel is provided with recesses (20) having small depth and large obtuse angle, while the top surface is anti-slip. Upper overlap elements (103) alternately protrude from sides of the panel beyond the collar (101) while lower overlap elements (103) are formed by reduction of thickness of the collar.
