Teplá, Kateřina ; Drápal, Aleš (advisor) ; Šťovíček, Jan (referee)
Title: Kerdock codes and around Author: Kateřina Teplá Department: Department of algebra Supervisor: prof. RNDr. Aleš Drápal, CSc., DSc., Department of algebra Abstract: Kerdock codes form a family of nonlinear codes, that contains more codewords than any known linear code with the same parameters. The main goal of this thesis is a connection of Kerdock codes with other areas of mathematics, mainly orthogonal geometry, combinatorics and cryptogra- phy. It describes theory of symplectic and quadratic forms on vector spaces of characteristic 2 and its relationship to Kerdock codes. Then it is pro- ven, that codewords of Kerdock code of constant weight form combinatorial 3-design. Finally usage of Kerdock codes in construction of Boolean bent functions and t-resilient functions, that are basis of many cryptographic pri- mitives, is analysed. Keywords: Kerdock code, Kerdock set, t-design, resilient function 1

Specific nutriton as a means of own self-creation of human pesonality - athletes. Case Study
TEPLÁ, Kateřina
Modern times bring a number of new views on the perception of the meaning and role of nutrition in human life. Observing the current lifestyle we can see considerable differences in particular individuals. This work deals with the problem of specific nutrition in connection with a regular sport activity as contributory factors which create the lifestyle of a sportsperson. This work concentrates on the individual for whom the strict and specifically focused nutrition in connection with a regular sports activity creates an inherent part of their life and is therefore the way to fulfillment ? to self-assembly in numerous directions. The goal of this work was to describe the composition of diet and its changes connected to different stages of a sportsman´s ? body-builder´s training plan. To map possible bio.psycho-social consequences. For the implementation of this research a qualitative research strategy was chosen. The research was carried out as a case study. The reference file has been made of a couple of sportspeople-body-builders. A woman and a man representing the current trend of fitness ? body-building followers for whom the connection of sport and well-focused nutrition represents one of their life´s values. The research was implemented in a wider timeframe, in a frame from May 2012 to January 2013. Semi-structured interviews, observation, evidence of different personal documents and activity results were used as data collecting methods. For the data analysis a qualitative analysis of written-down interviews, observations and personal documents, and activity results was carried out. From the conducted research of the particular case it was further found out that the nutrition of a body-builder changes during the different stages of the training preparation, even in rapid ways. Changes of the total amount of food, the change of the ratio or amounts of particular nutrients as well as changes in the choice of consumed food are observable. The observed changes of the sportspeople´s eating correspond with the theoretical knowledge given in the theoretical part of this work. At the bulk stage of this work the eating of the observed couple was characterized by a relatively high intake of energy, especially as the permanently higher intake of carbohydrates, a high intake of proteins and out of all the stages by the highest demanded feed of fat. In the cutting phase of the preparation the food of the observed couple was characterized, on the average, by a lower intake of energy, especially thanks to the limitation of the intake of carbohydrates, by the same or higher amount of proteins than at the bulk stage. The intake of fat in the man´s food basically didn´t change, but the woman decreased the amount of received fat compared to the bulk stage. At the final stage of the preparation the food of the woman was absolutely specific. During the resting and recovery phase of the preparation the eating of the observed couple did not show any strictly given requirements. Out of the research results it is clear that the sportspeople´s approach to food is varied, it differs according to the phase of training preparation. Food can be therefore either an enjoyment or the need to a sportsperson. For the observed couple, food isn´t a taboo. This specific and to some extent extreme lifestyle brings certain positives and certain risks with it. This work can be used as an information material for nutrition therapists focused on working with sportspeople, and for informing sportspeople themselves as well as the wider society about the possibilities of the effects of extremes in nutrition.

Working Migrants from Ukraine and Vietnam in the Czech Labour Market
TEPLÁ, Kateřina
This diploma work tries to describe the situation of working migrants from Ukraine and Vietnam. The theoretically part includes topics from the description of the elevation of working migrants on contemporary Czech labour market to social and cultural background of workers from Ukraine and Vietnam. The second practical part is based on four detailed interviews with a working migrant from Ukraine, a working migrant form Vietnam, a Czech co-worker of working migrant and an employer of working migrants. The sight of view of these four interviews is that working migrants have the same conditions as Czech employees, they came to Czech Republic to make money to rise the life standard of their families living abroad. There is enough work in their countries but they aren´t paid so well as in Czech Republic there. The working grades they execute are not interesting for Czech workers so these positions hadn´t been casted before they came to our country. They know that people have many prejudices to them there but they don´t admit them and try to pass judgment on Czechs individually. At the beginning each of them had an experience with some negotiator or {\clqq}client`` who had vindicated them their jobs and accommodations. They see the biggest problem in communication in our language but they are willing to learn speaking Czech. They don´t follow the progression of Czech justice and legislation and they rely on their employers in this case. They think that the biggest difference between their countries and Czech Republic is folks´attitude towards family and religion. They are willing to cooperate on changing the unfriendly attitude of our people towards them.

Parental Alienation Syndrome
TEPLÁ, Kateřina
Thesis deals with problems of Parental Alienation Syndrome (PAS). Theroetical part describes this phenomenon from the history of origination of PAS to current problems which are connected with this phenomenon (definitions, terminology, diagnostics, correction, etc.). Practical part contains questionnaire results which were sent to family and marriage counselling services in the Czech Republic. It flows from these results that in the Czech Republic most of the addressed counselling services are dealing with PAS therapy, however there is no unified system of therapy method. Most common used therapy method is meditation, which is carried out in most of the facilities by a man and a woman. As a programming parent is usually marked mother. Girls (daughters) were marked more often as victims of programming of one of their parents. The result also shows that counselling services are carrying over responsibility of the therapy to their clients, but not also to themselves and to their own abilities and skills of a therapist. Addressed counselling services show relatively high percentage of fruitfulness. According to addressed specialists working in family and marriage counselling services, skilled public is fairly acquainted with PAS problems, which leads to a ceratin hope that even more specialists will deal with these problems.
