The theory and practice in secondary aducation of the visul disabled students in the Czech republic
KŘÍŽ, Michal
The term visual handicap can be defined as an absence or insufficiency of visual perception quality. We can also say, that visually handicapped (similarly ZP) or person with visual handicap is a person with different types and grades of decreased visual ability. The human being receives approximately 85% of information from surrounding world by the visual sence, therefore it is evident, that an visual handicap affects the whole personality. Thereby we mean those people, by who the visual handicap affect common life activities and where the common optical correction is not sufficient. The number of severly visually handicapped persons of all age groups is in Czech Republic nowadays indicated to 60 000 persons. The estimation indicates the number of 5 - 20 visually handicapped children to 1000 new born children. In the Education law it is mentioned: Educational facilities arranges for children, pupils and students education, sporting and leisure time activities in addition to lessons and also in the working days off or during the holiday. The term leisure time is understood as a time, when people freely choose and perform activities, which bring them enjoyment, amusement, relaxation, activities which more or less renew their physical and mental abilities, possibly creative strength. This bachelors thesis is designated to everyone, who come into contact with visually handicapped students, to headmasters of common and special high schools, where the visually handicapped students are in the classes. This bachelors thesis would also improve awareness of leisure time activity possibilities and possibly it could help to extend the leisure time activities offer according to the students interests.

EVALUATE THE PERFORMANCE PARAMETERS OF THE BREEDS OF COMMON CARP AND ITS CROSSBREDS
KŘÍŽ, Michal
The aim of the thesis was to evaluate the performance parameters of the breeds of common carp and its crossbreds by using the top-crossing. On the maternal position the Hungarian synthetic mirror carp line (HSM) was used. On this line, males of HSM, Telč mirror carp (TeL), Northern mirror carp (M72) and Amur mirror carp (AL) were crossed and a hybrid of Ropsha carp (ROP) and Tata carp (TAT) was used as their control group. Rearing of the tested groups was monitored from larval stage until their market size in ponds with a semi-intensive way of management in three localities (2 organisations). In the first year, each tested group was bred individually with internal control group of a different scaly covering phenotype in order to correct the influence of the environment on the weight achieved. In the second and the third year, all the groups were group-labelled and bred together in triplicate (three ponds) localities. In the individual stages of testing, the weight and the survival rate were recorded. Moreover, in the market size stage the biometric measurement and slaughtering value were evaluated. In the overall assessment of the results from all the localities carried out by the ANCOVA procedure, the highest weight at the K3 age was achieved by the hybrid HSM x AL (1413 {$\pm$} 31.5 g; Last square means {$\pm$} S.E.), whose weight was statistically comparable to the other hybrids (HSM x M72 a HSM x TeL). However, it was the only noticeably higher weight in comparison with the HSM (1257 {$\pm$} 31.5 g) with its ordinary heterosis effect of growth on the level of 12.4%. During the third year of testing, the survival ranged from 69.0 % in HSM x Tel to 73.4% in HSM x AL and the values were statistically comparable. The yield parameters (the proportion of the processed body, the proportion of filets with skin and the skinless ones) were similar in all the groups. In the previous periods of testing the results reflected the situation in the market size. As a result, it is concluded that preferably the hybrid HSM x AL could be exploitable in commercial breeding.
