In paper we present a case study of the radio dispatching communications for providing the voice service during mass events of the “Lednica 2000” Youth Meetings. The presentation is supported by over 20-year experience in organization of this event every year. We also describe a FM radio system deployed during this meeting for broadcasting the English translation.

In 1998 and I 999, the research on the contents of entomofauna settlement of Heracleum Sosnowskyi Manden was carried out at Mochełck, and in 1999 - at Minikowo near Bydgoszcz. Useful insects were the most abundant group in the tested habitats. Based on the results of the investigations, it can be concluded that only two species: blunt's flat-body (Depressaria depresel/a Hb.) and celery fly (Phi/lophylla heraclei L.) may be of any importance in the fight against population of this plant.

This publication begins a series of works devoted to the analysis of the semantic derivation of selected Proto-Slavic roots in Macedonian and Polish. The aim of this work is to capture the parallels and differences in the evolution of the two confronted – though rather distant – languages. We obtain Macedonian and Polish visualizations of the world.
