Material printing on R2R printer
Knobová, Klára ; Vališ, Jan (referee) ; Veselý, Michal (advisor)
This diploma thesis deals with material printing using roll to roll material printer. Several kinds of printing inks were prepared and their parameters, like viscosity and homogeneity were optimized. Corona treated PET foil was used as the flexible substrate. Thin layers of function material were prepared by coating by using the smooth cylinder and slot die method. Layers homogeneity was characterized by optical density. Layer thickness was measured by profilometer.

Material printing of light dosimeters
Kabelková, Markéta ; Vališ, Jan (referee) ; Veselý, Michal (advisor)
This diploma thesis is focused on material printing of light dosimeters, especially printing of dosimeters for visible light and two types of UV radiation dosimeters. The aim of this work was to convert optimized systems from laboratory scale to pilot plant and to prepare individual systems for large-scale printing. The experimental part deals with the preparation and gradual scaling of compositions to a pilot scale, including optimization of individual components. Problems which were found during scaling up are discussed. A roll-to-roll material printer with slot-die technique was used to convert to a pilot scale. The prepared layers were exposed and their color changes was studied in detail. In addition to printing optimization, the thicknesses of the prepared layers and their resistance were determined, as well as tests of shelf life and reaction of dosimeters to ozone. According to the tests which were performed, guidelines for quality control of light dosimeters printing were compiled.

Emotional intelligence of teachers
VALIŠ, Jan
This bachelor thesis deals with the emotional intelligence of teachers. The aim of this work is how teachers perceive their competencies in the field of emotional intelligence. The theoretical part consists of three chapters which are devoted to emotional intelligence, helping and teaching professions and teacher's personality. The practical part is based on in-depth interviews and model situations solution. The research group consist of five elementary school teachers (three women and two men) and five elementary practical school teachers (also three women and two men) aged from 33 to 61 years, while the length of their practice is between 7 to 36 years. The data were analysed and classified into (After the data analysis were make) categories which are subsequently interpreted.
