Kostelník, Jan ; Kouřil, Jiří (referee) ; Polívka, Michal (advisor)
The introduction of this Master’s thesis describes a historical and technological evolution of the terminal application, including its advantages and disadvantages. In the following part, a general description of the services and their understanding are mentioned. The benefits and general advantages of the terminal services are described. For the each type of the terminal service, all the functions, options, exact advantages and disadvantages are described. Consequently, the study of the suitability of the compression is presented. On the demo application, the impact of an excessive (voluntary) loss of information is demonstrated. In the next part, the thesis deals with the most frequently used remote-control applications. The tests and comparisons are made as well. The fifth chapter is the fundamental part of this work. The design approach of the workbench is presented there. Consequently, the design approach and system implementation intended for the supervision and control is described. This system makes the user possible to observe other user’s activities and also to control their workstations. The supervising user can also access their drives and other memory devices, which are located in the monitored workstation. The communication is compressed and encrypted. The symmetric and asymmetric encryption algorithms are used there. In the following part, there are two supplementary applications mentioned – application for the key generating and network file manager. In the end of my work, the results of the performance test and also the design of other improvements are presented.

Monitoring system for detecting the motility and position of laboratory animals after anesthesia
Enikeev, Amir ; Vičar, Tomáš (referee) ; Čmiel, Vratislav (advisor)
This diplom work entitled "Monitoring system for the detection of motility and position of laboratory animals after anesthesia" focuses on the design and implementation of non-contact detection of the rat or mouse position in the enclosure with a transparent cover. The aim of this semester paper is to find suitable methods of realizing contactless detection of the position of a laboratory rat or mouse. This automatic positioning of the animal will be used as the basis for controlling the irradiator in the next follow-up work, which will "shade" animal movement and aim at the scar on the animal's back. The rat that is located inside our enclosure is either standard or movable after anesthesia. In this work I first deal with searches of automatic monitoring systems for detecting the position of animals in the enclosure. Then, in the practical part, I test three types of cameras for image detection of rat position. Evaluation software for motion analysis will largely be solved in the follow-up diploma thesis.Project made like monitoring and detecting software based on OpenCV.

Monitoring system for detecting the motility and position of laboratory animals after anesthesia
Enikeev, Amir ; Vičar, Tomáš (referee) ; Čmiel, Vratislav (advisor)
This diploma thesis, entitled "Monitoring System for Determination of Motility and Position of Laboratory Animals After Anesthesia", focuses on the design and implementation of contactless detection of the position of a rat or mouse in an enclosure with a transparent cover. The aim of the semester work is to find suitable methods of realization of contactless detection of rat or mouse position and to automatically determine and display average speed or other movement characteristics. The assignment arose from the needs of animal monitoring after curative intervention and also as a necessary utility for future "shading" animal movement (automatic targeting of the scar on the animal's back). The rat, which is located inside our enclosure, is either moving as standard or is dazed after anesthesia. In this work I deal first with search of automatic monitoring systems for detection of animals in the enclosure. Then in the practical part are tested three types of cameras for visual detection of rat position and a script for automatic detection and analysis of rat movement is designed. The system works like a camera eye which in real time is able to find the area of a black box in its field of view and then limit the detection area to the size of this box and then automatically detects the center of gravity and counts. and evaluates the obtained speed with an average calculated with a test of 10 mice - voices on the screen the mouse status in the previous ten seconds. for no stressed animal The rat that is located inside our enclosure is either standard or movable after anesthesia. In this work I first deal with searches of automatic monitoring systems for detecting the position of animals in the enclosure. Then, in the practical part, I test three types of cameras for image detection of rat position. Evaluation software for motion analysis will largely be solved in the follow-up diploma thesis.Project made like monitoring and detecting software based on OpenCV.

EEG Biofeedback Human Brain - Computer Interface
Kněžík, Jan ; Kořenek, Jan (referee) ; Marušinec, Jaromír (advisor)
This master thesis dwells on EEGbiofeedback (also called Neurofeedback) interface of human brain and the computer and its concrete realization in Java programming language. This system is founded on the basis of the computer, which is accomplishing biological feedback (biofeedback) and the electroencephalography (EEG) by helping that state's scanning of user's brain is realized. By this way is possible to practise the human brain effectively to achieve better concentration, the elimination of sleeping and learning deficiency. Hereafter is the suggestion of direction control of computer mouse by EEG device incorporated, which makes it possible for the man to regulate the direction of the cursor's movement on the screen by the frequency of brain's oscillation. The motivation for solution of this problem is the effort to help to handicapped people to communicate with surrounding world. The introduction of this paper contains the basic facts about human brain, electroencephalography and EEG biofeedback. The following chapters dwell on the specification of claims to developed application, its suggestion and description of actual realization. The final part relates to the BCI (Brain-Computer Interface) systems and suggestion of computer's control by EEGappliance with evaluation of attained results.

Maternal effect in selected rodent species: positive and negative effect on offspring fitness
Malá, Jana ; Landová, Eva (advisor) ; Stopková, Romana (referee)
This work describes the most studied mechanisms which could be classified as maternal effects. Here I focus on the effects of body weight, health status, intestinal microflora and age of the mother in model rodent organisms. I also present factors such as the position of the young in the uterus, population density, stress and especially maternal care, which accompanies this entire work. Each of these mechanisms can positively or negatively influence offspring fitness, depending on specific environmental conditions. Maternal behaviour is presented here in the form of research, which documents both epigenetic and genetic influences acting on its final form. Maternal care as an element of maternal behaviour shows a different measure between individuals, indicated by the frequency of licking and cleaning offsprings. By evaluation of maternal care, we can find in laboratory populations two stable phenotypes of individuals with different behavioural manifestations in terms of sexual behaviour, stress reaction, aggression or cognitive abilities. The discussion critically evaluates whether maternal care really affects reproductive success and whether it can therefore be considered an adaptive mechanism. According to the available information, low maternal care appears to be a more beneficial strategy in...

In vitro 3D organization of the mammalian testes
Zahradníková, Hana ; Tlapáková, Tereza (advisor) ; Janečková, Lucie (referee)
A testicular organoid that would sufficiently recapitulate the architecture of the testicular tissue and at the same time be able to provide the complete process of spermatogenesis in vitro has not yet been created. Achieving this goal would mean the development of a 3D model of the testis, which would mimic the in vivo situation in terms of cell arrangement and could thus contribute to a deeper understanding of the physiological functioning of the testicular microenvironment. Among other things, such a model has a great potential for clarifying the causes of male infertility and finding treatment options. This thesis dealt with the generation of organoids from mouse or human testicular cell suspensions, which can also be used, for example, to study de novo organogenesis. A total of four 3D culture systems were tested, of which the soft agar culture system (SACS) achieved the best results. Furthermore, as part of this thesis, the procedure for preparing testicular organoids for light sheet microscopy was successfully introduced and optimized, enabling the evaluation of their internal structure. From the testicular cell suspension of a 5-day-old mouse, it was possible to prepare testicular organoids, the structure of which in some respects resembled the organization of the testis in vivo. The...

Laboratorní test disasortativního párování u hraboše polního - literární rešerše
BÍLKOVÁ, Pavlína
Petrásková P. (2019): Laboratorní test disasortativního párování u hraboše polního - literární rešerše [Laboratory test of disassortative pairing in the common vole - literature search. Bc. Thesis in Czech]-49 pp. , Faculty of Sciences, University of South Bohemia, České Budějovice, Czech Republic. The aim of this work is to use the literature research to map current knowledge about the effect of odour preference on reproductive success in mammals focusing on voles. As assortative pairing is referred to each form of non-random pairing. Most of the time is meant a situation in which individuals who have similar phenotypes pair more often. The opposite is the situation where individuals with different phenotypes pair more often. This is sometimes referred to as negative assortative or disassortative pairing. In particular, this study deals with non-random pairing among to body odour . These are mainly linked to genes for the major histocompatibility complex (MHC) in animals, which play a key role in the immune system. MHC gene products found in various body secretions form the specific odour of each individual. In the research part were searched question for following questions: How is the breeding partner chosen? Is Assortative or Disassortative Pairing More Frequent? What information does body odour convey? What channels is the odour information transmitted and received? How is odour preference testing solved in laboratory conditions? In the practical part, a plan of the experiment is presented in which T-labyrinth will play the main role in determining the odour preference. Under laboratory conditions, voles will have plenty of time to complete the process

LINC complex: The link between chromatin integrity and sperm motility
Šanovec, Ondřej ; Komrsková, Kateřina (advisor) ; Lánská, Eva (referee)
The LINC complex (Linker of the Nucleoskeleton and Cytoskeleton) is a protein structure located in the nuclear membrane that connects the cytoskeleton with the nucleoskeleton. This complex can be found in every mammalian cell including the gametes. However, here the LINC complex is more diverse and less studied than in the somatic cells. In this thesis, the LINC complex and its role in spermiogenesis have been studied in wild-type and Protamine 2 knockout (Prm2-/- ) mice. Protamines are small proteins that replace histones during spermiogenesis. The mouse model generated by the group of prof. Hubert Schorle has a deletion in Prm2 in exon 1 and its sperm possess a surprising phenotype including complete loss of motility. Therefore, it was hypothesized that the LINC complex might be responsible for miscommunication between the sperm head and tail which leads to the loss of sperm motility. Results from this study suggest that the LINC complex is not influenced by Prm2 deletion, however, actin dynamics, cytoskeletal motor proteins and tubulin acetylase/ histone deacetylase activity might be impaired. Prm2-/- sperm have a significantly higher abundance of β-actin compared to the wild type. Next, Prm2-/- sperm also show a different pattern of acetylation of α-tubulin but no change in the abundance of...
