Biofeedback and its practical use
Dvořák, Jiří ; Hrozek, Jan (referee) ; Čmiel, Vratislav (advisor)
The aim of this work is describe common methods of biological feedback therapy that is used to treat some psychosomatic diseases. Subsequently, the description is focused on minimal brain dysfunction treatment by the help of EEG biofeedback. Properties and technical requirements for this therapy are concretized. The last part of this thesis is dedicated to the design and realization of practical software tool for EEG biofeedback therapy which is made in LabView 7.1. The M535 acquisition unit and NI USB-6221 measuring device are used for hardware solution.

Build Parallelization in Jenkins Environmnent
Lukášová, Michaela ; Zachariášová, Marcela (referee) ; Dolíhal, Luděk (advisor)
The goal of this bachelor's thesis is parallelization of building Codasip Studio, highly automated developement environment. It focuses on parallelization in Jenkins environment. The implemented solution is mainly focused on speeding up the actual build process. The solution uses a number of Jenkins plugins and several shell scripts, which ensures start of compilation, installation or creation of the final package.

Organizational culture of secondary vocational school
Grygorsky, Vito ; Šikýř, Martin (advisor) ; Tureckiová, Michaela (referee)
Univerzita Karlova Pedagogická fakulta Centrum školského managementu DIPLOMOVÁ PRÁCE Organizační kultura střední odborné školy Organizational culture in high school Vito Grygorsky Vedoucí práce: Ing. Martin Šikýř, Ph.D. Studijní program: Specializace v pedagogice Studijní obor: Management vzdělávání 2018 The diploma thesis deals with the issue of organizational culture in secondary vocational school. The aim of the thesis is to identify the values and artefacts that constitute the organizational culture of the secondary vocational school. The diploma thesis is divided into three parts, which are connected to each other. The first part is focused on the theoretical background of organizational culture, its elements, structure, models and resources. In the second part of the thesis the theme of organizational culture is further developed. It deals with management issues, strategy and climate of the organization. The third part of the thesis examines the organizational culture of a specific secondary vocational school according to the defined basic questions of the thesis. School staff consider cultural school values to be the front of its artefacts, and most employees are satisfied with organizational culture at school. The research carried out at school confirmed both assumptions.

Freeze-fracture technique and artefacts caused by processing conditions
Vaškovicová, Naděžda ; Valigurová, A. ; Hodová, I. ; Melicherová, J. ; Krzyžánek, Vladislav
Freeze-fracture technique is a method used to visualise membrane surfaces of cell organelles. This method is based on cryo-fixation that stabilizes samples. The sample is rapidly frozen in nitrogen, and cut in the chamber under a vacuum and low temperature. Glycerol is used as a cryoprotectant preserving the fine structure of cells in their native stage. Although, cryoprotectants serve as a substitute for water and protect against ice crystal production, they could also affect the form of fracture through biological membranes. Figure 1 shows structures in a sample frozen in the presence of 25% glycerol. The temperature of the apparatus was not low enough during the process of fracturing and etching the sample. The structure of cells seems to be deformed due to melting glycerol. In contrast, figure 2 shows a replica with fine structure of frozen and proper good form of fracturing. The cells used for this study were human leukemic cells (HL-60). Another artefact is shown in figure 3A, compare with 3B. Each sample has to be fractured with a specific speed of cut. The force used for fracturing the membranes has to be set to optimal conditions, which depend on a hardness of sample and a coherence of drops. Low speed and unstable coherence of drops resulted in sample fragmentation. High speed of cut could cause cross-section of cellular structures, similar to ultrathin sections. Figure 3A shows fragmentation of nuclear membrane. This sample was not fractured, it was fragmented due to unstable coherence of drop. This overview shows how a combination of different conditions including the physical properties of the sample, cryoprotectants used and temperature could affect the form of fractures and hence significantly affect interpretation of morphological structures.
