  Throughout our research we have made potassium-humate from brown coal of Dudar. With potassiumhumate and copper(II)-sulfate we made test sheets of linter cellulose fibers. The surface energy, surface wettability, CIE Lab color-coordinates changing, bending resistance and tensile strength of the produced test sheets has been examined. There was no big difference in the different samples during surface energy and wettability testing. Examination of mechanical properties suggests that potassium-humate content increases bending resistance of the test sheets. The bending resistance of samples increased by 32%, 100% and 336% compared to the control test sheets while adding potassium-humate.

  In Hungary, the emergence of a talent market for organizations is due to the growing demand for talented workers. The talent's definition, the exploration of the factors affecting the talent market's demand and his supply are necessary to the overview. With the emergence of the talent market, we will also carry out an important analysis of the changes in the labor market in Hungary as well as the shortage of labor shortages. In the labor market today, different generations are present, who have different expectations for their employer and work environment. The lack of skilled workers is attempted by organizations with different methods. One of these is the ability of companies to become a talent-magnet, resulting in a higher number of employees in their area of activity. In areas where labor shortages are high, more and more attention is paid to automating processes. During the research, I worked on the related literature and studies to determine the factors influencing the talent market.

  Attitude change is needed in design of timber structures. Truss girder made of timber elements wi th small cross sections can be used on large spans. Constructing structures with the use of these prefabricated trusses reduces the need of in-site work, and makes the use of ti mber structures economic. Rods of truss can be connected with the use of hardwood stud. On this way all steel components can be eliminated from the truss, so it can be used in aggressive environment as well. Dowel type connection, with hard wood stud is the subject of the present research. Hardwood studs were investigated individually and also as the part of separated connections of the truss girder.
