Sexual behaviour of bulls in natural breeding
GOUBEJOVÁ, Jaroslava
The aim of this thesis was to capture basic categories of behaviour and sexual behaviour of bulls in natural breeding, acquire and evaluate data from behavioural observations. The observations were realized in the village Obora u Tachova and were focused on a pedigree bull of a breed called Limousine (ZLI 796) and a herd of 26 breeding-cows, crossbreed beef cattle which are reared in the system of cows without market production of milk. The observations were made during the period from March 2013 till March 2014. The pedigree bull was in the herd of cows classified year-round. Monitoring with subsequent recording from the observations was performed whenever there was a breeding-cow in the herd and was discovered by a regular inspection of the herd observer. The snapshot method was used for the observations with the length of an interval of 5 minutes. From the ethological observation it emerged that the category of lying influences sexual behaviour of the bull towards to a breeding-cow the most. The value decreased from 15.97%, which was recorded in case of no breeding-cow in the herd, to 11.87 % in case of one breeding-cow in the herd and, if there were more breeding-cows the value fell to 2,51 %. For the category called movement, the value increased from 12.50 % to 16.03 % in case of one breeding-cow and when there were more breeding-cows, the value increased to 22.17 %. Sexual behaviour of the bull has only a low effect on feed intake, which was always held on the level of 47 % and the category called stall which was in case of no breeding-cow and one breeding-cow 24 %. For more breeding-cows the values increased to 27%. It was found out that the length of a movement extends at the expense of lying. The number of failed attempts to copulate the bull with one breeding-cow decreased from 17.91 experiments to 12.22 experiments with two or three breeding-cows. In case of successful copulations, the value increased from the original 5.73 copulations with one breeding-cow in the herd to 6.56 copulations with the average number of successful copulations 3.11 per one copulation. The highest intensity of copulation passed off in the morning between 8 a.m. to 10 a.m., the second peak occurred around 5 p. m. in the afternoon. The success rate of the bull in the herd of the breeding-cows, where there was only one breeding-cow, was 81.82 %. The success rate of the bull in the herd of breeding-cows, where there were two or three breeding-cows, was 72.73 %. The total fertility of the bull reached to 91.30 %.

Survey Information for Citizens of the Czech Republic on HIV
Milfaitová, Tereza ; Lešetický, Ondřej (advisor) ; Jankůj, Miroslav (referee)
First references of HIV virus in the Czech Republic are dated with the year 1986 and thousands of people have been infected since then. However, medication for complete recuperation have not been invented yet. This is the reason why the HIV virus belongs to the most feared venereal diseases. The issue of HIV/AIDS is being constantly discussed, especially at the beginning of each year when the statistics of this disease are published by the National Health Institute of the Czech Republic. The spreading of this disease cannot be stopped but it can certainly be slowed by effective preventive programs with an emphasis on sexual responsibility. Therefore, the aim of my work is to explore awareness of the Czech inhabitants about this disease and to find out their own sexual responsibility, which certainly has a big influence on spreading this infection.

Do condoms prevent or help the spread of HIV virus?
Jánská, Zuzana ; Bartoň, Petr (advisor) ; Chytil, Zdeněk (referee)
The male condoms were massively expanded to Africa in 1990s as a result of growing HIV prevalence in most parts of Sub-Saharan Africa. Many transnational non-profit organizations together with national governments were engaged in this expansion of condom distribution. The biggest condom donator are the United States of America which have already provided tens of milliards of dollars to fight against AIDS by distribution of condoms. Was this financial aid used effectively and did the money have the right intended effect? Scientists agree on the statement that the effectiveness of condoms as contraceptives is around 90%. What is the efficiency of using condoms helping against the transmission of the virus HIV, if a single HIV virus cell is much smaller than a sperm cell? With the help of regression analysis using panel data we can give a definite answer to the crucial question -- do condoms help or prevent the spread of HIV virus?

Informedness of primary school pupils in the town of Milevsko about HIV/AIDS
VINKLEROVÁ, Lucie
AIDS is a pandemic disease known for almost three decades, and the most effective prevention is general informedness and responsible sexual behaviour. Especially young people should know as much as possible about the disease to be able to protect themselves effectively. The objective of this thesis is to find the sources of information about HIV/AIDS and the level of knowledge about this disease in adolescent population or pupils in the highest grades of Milevsko primary schools. The theoretical part of this thesis focuses on adolescents, their life style and especially the awakening interest in sexuality and their sexual behaviour. I try to find the effects that may influence these sexual aspects, including sex education at school and in the family. I deal with the influence of information about HIV/AIDS on sexual behaviour of young people. I also briefly describe AIDS prevention programs for adolescents. My research conducted in the questionnaire form shows that pupils are generally informed about the issues of HIV/AIDS; however, certain factors must be addressed in more detail. A positive finding is that up to two thirds of the respondents believe that the information about HIV/AIDS will affect their future sexual behaviour to avoid infection. However, mere informedness is not enough to prevent the spread of the infection. It is also necessary to implement prevention programs, to provide quality information within sex education, but also to direct the public, through the media, towards responsible sexual behaviour of individuals. Finally, it is important to ensure and promote an atmosphere in society that will be positive and that will not help spread the infection.
