Gröbnerovy báze v kryptografii
Hubáček, Pavel ; Stanovský, David (advisor) ; Šťovíček, Jan (referee)
The thesis focuses on the use of GrÄobner bases in cryptography and especially on applications in cryptanalysis of block ciphers. Some elementary concepts from the theory of GrÄobner bases are introduced together with Buchberger's algorithm, a method for constructing such bases. The principle of solving of poly nomial systems using suitable GrÄobner bases is explained. This is followed by pre sentation of modern algorithms that improve the Buchberger's algorithm. In the last part of the thesis present results achieved by GrÄobner bases are summarised and the notion of algebraic cryptanalysis is introduced. In algebraic cryptanalysis we transform breaking of given cryptosystem into a problem of solving polynomial equations over some nite eld. Examples of polynomial descriptions of block ciphers are provided together with some experimental result on arising polynomial systems.

Comparison of Export Support Systems in Austria and the Czech Republic
Zbranková, Lenka ; Král, Petr (advisor) ; Vokáč, Matěj (referee)
This master's thesis deals with the comparison of export support systems in the Czech Republic and Austria. In the first chapter, the terms "export support" and "export credit agencies" are defined and instruments of export supporting policies as well as their positive and negative aspects are listed and EU regulation and policies in this field are briefly described. A short description of the Czech Republic and Austria follows. Special attention is paid to the following analysis of export strategies and export credit agencies in both economies. This descriptive theoretical part is complemented by a practical case study carried out in cooperation with TOSHULIN, a.s. -- a successful producer and exporter of machinery. Both systems of export support are evaluated from the point of view of the company's sales department. The thesis concludes with an evaluation of the topic, a comparison of the effectiveness of both export support systems, and the author's suggestions for potential innovation and improvement in this area.

An Existential and Non-religious Interpretation of the Christian Faith
Holubec, Tomáš ; Funda, Otakar A. (advisor) ; Hauser, Michael (referee)
V této práci jsme analyzovali koncepty nenáboženské a existenciální interpretace křesťanské víry. V úvodu jsme si kladli spolu s Robinsonem otázku, zda lze tyto pokusy označit za reformaci analogicky k reformačnímu hnutí v Evropě patnáctého a šestnáctého století. Zdá se, že se Robinsonova naděje, že tyto pokusy o interpretaci evangelia rozpohybují podobný proces, jako se to povedlo v reformaci, nenaplnila. Přestože byly tyto pokusy zaměřeny na moderního, sekularizovaného člověka, zůstal tento člověk vůči této řeči hluchý. Možná to bylo způsobeno nejednoznačnou terminologií a určitou intelektuální náročností, kterou se nenáboženské interpretace vyznačují. Odhady a charakteristika "čtvrtého člověka" také neodhadly moderního a tím spíše postmoderního člověka přesně. Ano, do určité míry je takový člověk skeptický vůči všemu nadpřirozenému. Má výhrady vůči náboženským mýtům, zázrakům a dogmatům, zároveň však tento člověk hledá duchovní útěchu v nejroztodivnějších typech náboženství a duchovní sféry.

Péková, Kateřina ; Frintová, Dita (advisor) ; Pohl, Tomáš (referee)
76 Abstract (anglické resumé) Adoption - comparing of the legal regulation in the Czech Republic with the Federal Republic of Germany The dissertation compares adoption problems in the Czech Republic and in the Federal Republic of Germany. The First Chapter considers the historical development of adoptions in both countries comparing legal regulations. Principle of the full adoption is described in the first part of Chapter Two. The second part shortly explains the difference between revocable and non-revocable adoption, which is possible in the Czech Republic. Chapter Three is the most extensive one.

Legal capacity - a comparison of its legal regulation in the Czech Republic and Germany
Kalivodová, Markéta ; Salač, Josef (referee) ; Dvořák, Jan (advisor)
54 6 Závěr Problematika způsobilosti k právním úkonům ve vztahu k nezletilým se zakládá v českém a německém právu na zcela odlišných koncepcích. Původní římskoprávní základ, ze kterého i nadále vychází německé právo, byl v naší zemi opuštěn občanským zákoníkem z r. 1964 a koncepce pevných věkových hranic tak byla nahrazena koncepcí přiměřenosti právního úkonu rozumové a volní vyspělosti dítěte. České právo nestanoví věkovou hranici, pod kterou by dítě bylo absolutně nezpůsobilé k právním úkonům, což je podle mého názoru vhodnější přístup, nicméně německá právní praxe se mu brání s odvoláním na složitost dokazování existence vůle malého dítěte. Německým občanským zákoníkem se jako červená niť vine princip ochrany nezletilého (Minderjähigenschutz), naproti tomu české právo klade důraz rovněž na v německém právu potlačenou ochranu druhé smluvní strany. Rigiditu a nepraktičnost koncepce vycházející z pevných věkových hranic v německém právu překonávají ustanovení typu Taschengeldparagraph, možnost udělení omezeného generálního konsensu, ustanovení o právních úkonech nevyžadujících souhlas zákonného zástupce atd. Ochrana nezletilého, ochrana dobré víry druhé smluvní strany a zaručení principu právní jistoty, to jsou hodnoty, které se budou neustále střetávat při úvahách o vhodnosti toho či kterého řešení úpravy...

Racist legislation of Nazi Germany
Kubelková, Jana ; Horák, Záboj (referee) ; Seltenreich, Radim (advisor)
Tema moji diplomove prace je rasisticke zakonodarstvi nacistickeho Německa. Toto tema jsem zvolila, protože si myslim, že je třeba si připominat i stinne stranky pravnich dějin, abychom se z historie poučili a předešle chyby neopakovali. Diplomovou praci jsem rozdělila do osmi zakladnich kapitol. V prvni kapitole vymezuji zakladni pojmy rasismus a antisemitismus, rasove teorie a vůdcovsky princip, neboť tvořily integralni součast nacisticke ideologie. Druha kapitola obsahuje nastin politicke a ekonomicke situace v povalečnem Německu, postupny vzestup Nacionalněsocialisticke německe dělnicke strany v čele s Adolfem Hitlerem, převzeti moci nacisty a prvni fazi protižidovských opatřeni. Třeti kapitola se věnuje nejvyznamnějšim rasistickym zakonům, tedy tzv. norimberskym zakonům, a dvěma zakonům, jež se tykaly dědičneho zatiženi. V dalšich kapitolach jsem se zabyvala dvěma důležitými mezniky protižidovske politiky Německa. Prvnim je celonarodni pogrom z 9. a 10. listopadu 1938, tzv. křišťalova noc, kterou bych označila za předehru holocaustu. Druhy meznik představuje porada na tema "konečne řešeni evropske židovske otazky" znama jako konference ve Wannsee. 1

Gender Selection as a Topic of Bioethics
Hendlová, Tereza ; Kolářová, Kateřina (advisor) ; Kiczková, Zuzana (referee)
My thesis focuses on the topic of gender selection (deliberate determination of the child's gender which is now possible thanks to recent developments in reproductive medicine) from the perspective of biomedical ethics. The main question is whether the practise of gender selection complies with the 4 basic principles of bioethics against which all medical action should be assessed (principle of autonomy, non-maleficence, beneficence and justice). In the thesis, I distinguish between two main types of gender selection: gender selection for medical and non-medical reasons. The main focus is put on the second type, which is more ethically disputable, as it is not as directly related to the child's health and well-being as the first type. Gender selection for non-medical reasons is practiced in the context of multiple interactions of social, political, economic and other factors that all inform parental choices. One of the very influential factors is the medical discourse. For the purpose of complex contextualisation of gender selection for non-medical reasons, the concept of procreative liberty (introduced by J.A. Robertson) and feminist critiques of reproductive choices are presented. My main argument is that gender selection for non-medical reasons should not be legal and available as it has a high potential...
