Knowledge of 8th and 9th grade elementary school students about reproductive health
CHRSTOŠOVÁ, Vlasta
The Bachelor thesis entitled Knowledge of pupils in 8th and 9th grades in primary schools about reproductive health focuses on the level of awareness of pupils aged 13 -16 about the issues of menstruation, safe sex, contraception, pregnancy and sexually transmitted diseases. The theoretical part of the bachelor's thesis describes health and its division into reproductive and sexual. It also describes the reproductive organs of women and men, menstrual periods and menstrual devices, sexual intercourse, and the possibilities offemale and male contraception, as adolescents need to know how to protect themselves from unwanted pregnancies and sexually transmitted diseases. There are therefore individual chapters devoted precisely to sexually accurate diseases, pregnancy and abortion. The final chapter deals with the education of pupils on reproductive health issues and the role of midwives in the educational process. In the research part of the bachelor s thesis, a quantitative method was chosen as the method of research investigation. The data was collected through a questionnaire distributed to respondents on the social networking site Facebook. The questionnaire consisted of 36 questions, of which 23 were closed, 12 were semi-closed and 1 was open. The data obtained was processed and evaluated using Microsoft Excel and SPSS computer programs. Graphs showing the responses of boys and girls in the 8th and 9th grades of primary schools have been produced for each question. The research pool consisted of 101 respondents. Of the 8th grade, a total of 36 respondents were 7 boys and 29 girls. Of the 9th grade, a total of 65 respondents were 13 boys and 52 girls. The aim of this work was to find out what boys and girls of the 8th and 9th grades had knowledge about reproductive health, i.e. menstruation, safe sex, contraception, pregnancy and sexually transmitted diseases. 3 hypotheses have been established for the research part. The first hypothesis was to determine whether girls in 8th grade had greater knowledge of reproductive health than boys in the same year. This hypothesis has been disproved. The second hypothesiswas to determine whether girls in the 9th grade had greater knowledge of reproductive health than boys in the same year. The second hypothesis was disproved. The third hypothesis looked at whether 9th graders had greater knowledge of reproductive health than 8th graders. This hypothesis has been confirmed.

Sphenopterid type of true ferns from Carboniferous basins of Czech massive
Frojdová, Jana ; Pšenička, Josef (advisor) ; Kvaček, Jiří (referee) ; Rößler, Ronny (referee)
This thesis deals with the sphenopterid types of ferns from the Czech Carboniferous basins. Thesis is presented as a combination of two published papers in peer-reviewed journals, one manuscript in review and one manuscript ready for submission. The actual text of the thesis is a general introduction with introduction to the study subject of sphenopterid ferns, methodology, studied type collections, terminology and the result of my study. The introduction of the thesis provides a general overview of the ferns and history of their studies. All four papers presented here are focussed on modern redescription, redefinition, emendation and revision of genera Boweria Kidston, Dendraena Němejc, Sturia Němejc. Based on the revision of these genera, following two new genera were established: Kidstoniopteris gen.nov. and Paraszea gen.nov. A new species Boweria nowarudensis has been described during the course of this study. The "whole plant concept" was applied to all studied specimens, which allows to obtain as much information on the ferns morphology, anatomy, and reproductive organs as possible. This was combined with data on in situ spores as well as sedimentological and petrological analyses. The sporangial cells as annulus, stomium and apical cells and in situ spores were described for all genera and...

Characterization of subunit A of the Eukaryotic translation initiation factor 3 in Arabidopsis thaliana
Raabe, Karel ; Michailidis, Christos (advisor) ; Retzer, Katarzyna (referee)
In plants, translation regulation plays an important role during progamic phase, fertilization and seed development. The process of translation is mostly regulated in its initiation phase, where Eukaryotic translation initiation factor 3 (eIF3) is the largest and most complex initiation factor, consisting of 12 different subunits. In plants, single eIF3 subunit mutants caused various growth and development defects, depending on the particular subunit that was mutated. However, not all the plant eIF3 subunits were characterized to this date. The objective of this work was to functionally characterize the eIF3 subunit A using Arabidopsis thaliana as the main model plant. We described in this work that plant eIF3A proteins share high levels of homology and domain organization with eIF3A subunits from non-plant eukaryotic species but contain regions specific only to plants. Next we described that Arabidopsis thaliana AteIF3A gene is transcribed in highly proliferating tissues, its protein product localizes to cytoplasm and around pollen vegetative cell nucleus and observed an increased frequency of defective pollen grains and defects in seed formation in plants with T-DNA insertion localized to the AteIF3A gene. We also produced stable transgenic Nicotiana tabacum lines expressing heterologous AteIF3A...
