Study of behavior of vacuum insulation panels based on hybride core insulators
Zelenka, Jakub ; Plachý,, Jan (referee) ; Zach, Jiří (advisor)
The theoretical part of the thesis covers a literature search on the topic of vacuum insulations, their composition and the possibility of replacing the used materials with natural ones. Furthermore, the theoretical part focuses on the application of vacuum insulation in the construction industry and in other areas of use. On the basis of the conducted research, the design of hybrid core insulators based on natural secondary raw materials was carried out, which could be used as a partial or complete replacement of already used materials.

Study of the behavior of vacuum insulation based on secondary raw materials
Zelenka, Jakub ; Novák, Vítězslav (referee) ; Zach, Jiří (advisor)
The bachelor's thesis deals with an extensive literature research on the topic of vacuum insulation and their use in civil construction and other areas of application. The theoretical part is devoted to the composition of vacuum insulation and materials suitable for the production of their cores. Based on the performed research, the design of possible alternative core insulators based on natural secondary raw materials has been conducted. These can be used in the production of vacuum insulation.

Ronald Inglehart's theories and their contribution to historical sociology with regard to the publications since 2000.
Zelenka, Jakub ; Černý, Karel (advisor) ; Gramskopf, Rostislav (referee)
This diploma thesis aims to map the work that Ronald Inglehart published after the year 2000 and to include it in the concept of historical sociology. In my work I deal with a total of seven books, which I subject to critical reflection and at the same time I compare with other authors who commented on the given topics. The work will touch on theories of modernization, democratization, secularization and to a lesser extent civilization analysis. I will also add remarks and observations from the point of view of quantitative methodology, as Inglehart's theories are based on a large amount of quantitative data based on questionnaire surveys. The first part of my work deals with modernization theory, the next part deals with secularization and the third part focuses on the analysis of civilization. In modernization and secularization, I will first introduce versions of the theories that Inglehart and co-authors published during the first decade of the 21st century. After that, I will always reflect on recent work (2017- 2021). In the civilization part, which is the shortest, I will summarize his findings across his work. At the end of his work, Inglehart also makes predictions about future society. I also intend to analyze these findings in my diploma thesis. At the end of the work I evaluate the...

Interactive board in physics education
ZELENKA, Jakub
The thesis discusses using an interactive board in teaching science (physics) in the second stage of primary school. The thesis is divided into different parts dealing with technical principles of different interactive boards and the implementation of these boards into teaching science at primary schools. Using special software, the author created a set of teaching materials that was tested in practice. The test results were discussed with a qualified teacher and with the supervisor of the thesis. After that, the materials were adjusted so that their use would comply with targets of the thesis and their further use would be comfortable for teachers. To use the materials in a comfortable way, a comprehensive guide on their use was prepared.

Teaching of digital safety at the secondary and high school
ZELENKA, Jakub
This thesis deals with the issue of digital security at primary and secondary schools. This means first of all taking into account important aspects of computer security, such as protection of your equipment from dangerous viruses and pirate attacks with security software, the correct backup and manage their data. Furthermore, the focus on prudent behavior on the Internet, including caution against email threats, fraudulent behavior of some users and prudent use of social networks. It also provides password security with an emphasis on strong password management and also the issue of copyright law. The work included content analysis of Czech curricula given to the issue. They are listed here similar studies related to the topic of research theory and the main research of this thesis. In this research included a survey investigating the competence of students of the above schools in teaching computer security, the results are evaluated and compared with the findings of state documents related to the issue of teaching ICT.
