Security of data stored on the hard disk
Polášková, Markéta ; Hajný, Jan (referee) ; Martinásek, Zdeněk (advisor)
This work is dedicated to the security of data stored on the hard drive of your computer and using encryption. The first part explains the basic concepts of cryptography and describes her in history. In other chapters, this work is dedicated to a description of the side channels and attacks on these channels. How can the attacker obtain information from a cryptographic module. The following section describes the types of encryption they use nowadays and what are their weaknesses. Bachelor thesis continues with examples of individual encryption programs and device ICZ Protect Boot. The last part deals with resistance testing on equipment ICZ Protect Boot. Testing of resistance to flow analysis using a side channel. Finally, bachelor thesis deals with the analysis of communication between the computer and ICZ Protect Boot.

Evaluation of patient dose in mammography
Polášková, Markéta ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
Breast cancer presents serious epidemiological problem, in result of which die more than 2 000 czech women every year. Screening mammography is one of the most expanded and most effective examinations for early detection of this desease but one has to take into account an inconsiderable risk connected with the procedure based on X-ray ionizing radiation. This diploma thesis deals with evaluation of the dose absorbed by the tissue. It contains the description of evaluation of the average dose in glandular tissue on PMMA phantom, as well as results of the measurements on conventional and digital mammograph. A data file with exposure parameters from mammography screening is included and interpreted. Also the Monte Carlo method was used for the dose evaluation, the thesis contains the brief description of the method, concept of analysis model in mammography and results of simulations.

Equine-assisted therapy in the Czech Republic. Investigation of organizations engaged in equine-assisted therapy aiming at organization, theory and practice
Polášková, Markéta ; Kodymová, Pavla (advisor) ; Holda, Dalibor (referee)
Cílem této práce je provedení pilotního šetření v organizacích, jež se prakticky zabývají léčebným pedagogicko-psychologickým ježděním (LPPJ) v ČR. Představuje léčebné pedagogicko-psychologické ježdění jako metodu využitelnou v rámci ucelené rehabilitace a zamýšlí se nad rolí, kterou by v této oblasti mohl zaujímat sociální pracovník. Pro bližší nastínění metody je část práce věnována jejímu historickému vývoji, legislativnímu rámci a faktorům působícím v LPPJ, které pak ilustruje na využití metody u vybraných skupin klientů. Jsou specifikovány i požadavky na pracovníky a na nutné zázemí. Předmětem praktické části je samotné šetření v organizacích provozujících LPPJ. Zaměřuje se na zmapování současné situace v těchto zařízeních jak po stránce organizační, tak po stránce personálního zajištění a konkrétní praxe. Tato práce vychází z předpokladu, že v praxi se organizace i samotní terapeuti LPPJ potýkají s mnohými problémy. Zvláštní pozornost je tedy věnována jejich identifikaci a nástinu možných řešení. Pro zjištění potřebných informací jsem použila dvou typů dotazníků, které byly za tímto účelem zkonstruovány. První z nich je zaměřen na získání faktických údajů o konkrétním zařízení a druhý se zaměřuje přímo na terapeuty LPPJ a zjišťuje jak faktické údaje týkající se jejich vzdělání a dalších kompetencí v...
