Application for Demonstration of Hash Algorithms SHA-1 and SHA-2
Siska, Josef ; Petrlík, Jiří (referee) ; Novotňák, Jiří (advisor)
In this thesis, the theory related to the hash algorithms SHA-1 and SHA-2 is presented, along with a description of possible implementation of an application that demonstrates how these algorithms work. The first part of this thesis describes the principles of construction of hash functions, their use and history of selected hash functions. The two following chapters present conventions and algorithms of the SHA-1 and SHA-2. The next chapter describes the general concepts related to the attacks on the hash functions and selected attacks are presented in more detail. The last two chapters outline the design and implementation of an application that was created as part of this work. In the end the evaluation of results of this thesis and proposals for its possible continuation are presented.

Classification systems in the hospitals
Saliba, Walaa ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
Cílem této diplomové práce bylo nastudovat problematiku klasifikačních systémů v nemocnicích, které sledují především hospodářské požadavky hospitalizace. Následně bylo navrženo a naprogramováno webové rozhraní v prostředí Caché Server Pages (CSP), které poskytuje přístup k databázi CLINICOM. Pomocí webového rozhraní, je možno provádět klasifikaci pacientů do tříd MDC (Major Diagnostic Category), archivaci dat, výpočet DRG a další vybrané úkony. Webovou aplikaci by mohli využívat technicko-hospodářští pracovníci nemocnic a klinik jako jednoduchou pomůcku při své práci, respektive jako učební pomůcka biomedicínských oborů pří výuce zdravotnických informačních a klasifikačních systémů.

Dendritic cells and autoimmune diseases with a view to type 1 diabetes mellitus
Chrástová, Iveta ; Štechová, Kateřina (advisor) ; Krulová, Magdaléna (referee)
Dendritic cells (DC) are professional antigen-presenting cells (APC) that play an essential role in the induction of immune responses. DCs develop from CD34+ hematopoietic stem cells in bone marrow and their role is uptake, processing and presentation of antigens to T cells. DCs can be divided into two distinct subset of cells, myeloid a plasmacytoid DCs. Myeloid DCs (mDC) develop from hematopoietic cells in the presence of GM-CSF and TNF-α or from monocytes in the culture with GM-CSF and IL-4, then with CD40L they mature and produce a large number of IL-12, which is important in driving CD4+ T cell to type Th1. The development of pDC is CD40L and IL-3 dependent and Flt3-L supports this process as well. The essential role of pDC is that they secrete a large amounts of type I IFN in the responses to viruses and so they maintain the antiviral stage. To recognize the viruses pDC express Toll-like receptors 7/9. DCs have on the surface also other groups of receptors, e.g. C-type lectin-like receptors, RIG-I-like receptors and NOD-like receptors. They play the role in the various diseases, mostly autoimmune diseases, in which the immune system recognizes self tissues and activates against them the immune response. Dendritic cells function is that they are competent to activate T cells, in the most cases...
