Krejčí, Jan ; Růžička, Květoslav (advisor) ; Brodec, Jan (referee)
This diploma thesis seeks to characterize and critically evaluate current development in the field of Online Dispute Resolution. In particular, interpreting international legislation focusing on present development and trends in this alternative dispute resolution, with help of Information and Communication Technologies. This thesis is divided into a total of seven chapters, which four of them are considered essential. The first is the second chapter, where the author of the thesis deals with the legislation of the Online Dispute Resolution in the Czech Republic. Secondly, the third chapter provides an explanation related to the domain disputes in the Czech Republic, the EU and the rest of the world. The fourth chapter deals with the development of legislative initiatives at the European Union level. Of particular note being, the European Union Regulation No. 524/2013 on online dispute resolution for consumer disputes. Further to that, chapter 5 deals with the activities of the The United Nations Commission on International Trade Law conducted by the third working group. In conclusion, the author notes that the main goal of the diploma thesis, namely the provision of an overview of the legislation of the Online Dispute Resolution, developing possibility of alternative dispute resolution, has been achieved.

Implementation of IoT Communication Protocols Utilizing UniPi Module for Raspberry Pi
Krejčí, Jan ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
Presented diploma thesis is focused on the implementation of Wireless M-Bus protocol to embedded device RaspberryPi with expansion board UniPi. The protocol is implemented in Python with Wireless M-Bus devices communicating via IQRF transceiver connected to the UART bus. The theoretical part is focused on an overview of embedded devices for the IoT, the possibility of their expansion. Further, the UniPi expansion board and Wireless M-Bus transceiver are detailed. First part of the thesis focuses on the Wireless M-bus layers, which provides a basic knowledge for understanding the practical part. The theoretical part concludes overview of captured devices including a description of their data units. In the practical part is the implementation of the sample application for receriving data from a Wireless M-Bus sensors. The application is able to read data from devices transmitting encrypted communication.

New diagnostic and therapeutic aspects of inflammatiory cardiomyopathy
Kuchynka, Petr ; Šimek, Stanislav (advisor) ; Krejčí, Jan (referee) ; Gregor, Pavel (referee)
Introduction: Inflammatory cardiomyopathy (DCMi) represents a non-familial form of dilated cardiomyopathy (DCM) and endomyocardial biopsy (EMB) is crucial for its diagnosis. Aims: To assess the prevalence of DCMi in patients with DCM of unclear origin, to evaluate the significance of serological tests for antibodies against infectious cardiotrophic agents and to analyze the effect of specific therapy guided by EMB results. Methods: EMB was performed in 56 subjects (mean age 52 ± 10 years) with DCM of unclear etiology and left ventricular (LV) ejection fraction (EF) < 40% with a history of heart failure less than 1 year. EMB samples were analyzed by immunohistochemistry, polymerase chain reaction (PCR) and electron microscopy. Results: Immunohistochemical examination revealed myocardial inflammation in 26 patients (46%), the PCR method detected genome of microbial agents in 32 patients (57%). Electron microscopy showed the presence of particles of microbial agents in 41 patients (73%). Serological blood tests found no IgM antibody positivity against any of the investigated microbial agents. Targeted antibiotic therapy in patients with evidence of Borrelia burgdorferi (Bb) genome in the EMB led to a reduction in LV size, improvement of LV EF and alleviate symptoms of heart failure. Conclusion: DCMi...

Genetic and clinical correlates in hypertrophic cardiomyopathy
Čurila, Karol ; Gregor, Pavel (advisor) ; Málek, Ivan (referee) ; Krejčí, Jan (referee)
Hypertrophic cardiomyopathy (HCM) is a hereditary disease, which is caused by mutations in genech coding for proteins of carcomere of heart muscle. Disease is characterised by wide genotypic and fenotypic heterogeneity. Since the 90-th of 20-th century, when the first mutation responsible for HCM was identified, many research was done in detecting the correlation between mutant gene and clinical picture of the affected patient. As the first in Czech republic, we determined the frequencies of 4 most common genes in HCM in czech patients. We figured out, that spectrum of mutations is somehow different from another populations. We didn't find any correlation between specific gene mutation and morfologic and clinical characteristics of affected subjects. In our study with AT-1 receptor blocker - candesartan, we demostrated positive effect of candesartan on level of hypertrophy and function of the left heart ventricle and clinical symptoms of the patients with HCM.
