Name Writing and Reading of Preschool Age Children
Kubíková, Adéla ; Viktorová, Ida (advisor) ; Špačková, Klára (referee)
This bachelor thesis deals with the issue of writing and reading personal names in the preschool period. The personal name is very attractive for the children, and therefore they usually want to learn to write this particular name first. Thanks to the signature, the children gradually become acquainted with the system of writing and the entire culture of writing. In its theoretical part, it briefly describes the individual development characteristics of a preschool child. Further on, it deals with the development of writing in the preschool age and the development of abilities and skills needed to learn to write and read. The focus of the paper lies in the practical part. It is the author's own empirical research of a heterogenic group of children aged 3-6 years. Children had several tasks, such as sign up and then re-read their signature or recognize their name in a short text. The aim of the research was to find out the relationship of the preschool children to their signature. Attention was focused both on the graphic form of the signature, and on the children's notion of the social importance and usefulness of signature. The bachelor thesis also reflects on whether it is more difficult for the children to write their name or to read it.

Signature of Preschool Age Children
Ondráčková, Blanka ; Viktorová, Ida (advisor) ; Páchová, Anna (referee)
The bachelor thesis devotes to the issue of writing and understanding the signature of preschool age. The theoretical part, after a concise summary of the characteristics of the developmental period and defining the relationship between literacy and graphomotory, primarily egages in children's understanding writing and perception of printed words. It mentions relevant researches related to the topic of child ability to write their name and the influence of this skill to the next child development. It also deals with the notion of "signature" and the reasons its attractiveness for preschool children. The focus of this thesis is own empirical research, the aim was to determine the relationship of preschool children to the signature. The first point of interest was the linguistic understanding of the signature and the other children's image of its social importance and usefulness. The attention was paid to the graphic representation of the signature and the ability to read it subsequently and repeatedly in context of linguistic understanding of the signature. This part of the research is focused on children's understanding of the print system and the function of letters as placeholders, ie the awareness that isolated letters do not mean itself. The children's view of the importance of the signature...

Realization of attack on SHA-1 hash function
Dziura, Michal ; Hajný, Jan (referee) ; Malý, Jan (advisor)
The bachelor thesis is concerned with hash functions, SHA-1 function and its implementation in Java. The thesis describes weaknesses of this function and implements the implementation of the selected attack leading to the revelation of source text or attack based on targeted falsifying hash. This work also describes characteristics of hash functions, constructions and their use. The last part deals with a description of the attack on the hash function SHA-1 with the complexity of the 2^69.
