Diversity and function of pattern structures in the microworld
Hirnerová, Anna ; Škaloud, Pavel (advisor) ; Němcová, Yvonne (referee)
This thesis summarizes current knowledge of patterns and structures at various scales, with an emphasis on the use of these patterns in the microworld and also on the materials that are most often used. Patterns are applied in all areas of natural processes and human activity. There are many analogous models at different scales, but we do not know if they have the same self-organizing mechanisms. Many patterns formed by microorganisms can be prepared without their presence, on the basis of physical and chemical methods, so they are probably created under certain parameters that can be influenced by a given protist. These patterns are evolutionarily advantageous for microorganisms, because they provide them with a number of functional adaptations, mainly in connection with defense against predators and movement in the water column, which is based on the organism's life strategy. The mathematical description of the pattern is extremely important for its further research and for determining the laws that have allowed the organism to benefit from its parameters. Keywords: pattern, structure, convection, reaction - diffusion model, geometry, protist, microorganism, skeletons, shells, scales

Reforms of the writing alphabet for the youngest. Is it Time for a Change?
Ventová, Kamila ; Špirk, Ivan (advisor) ; Wildová, Radka (referee)
The theme of the diploma dissertation became a view of a field of alphabets (letters and types) in contexts of communication, history, art and education. The theoretical part is focused on historical, contemporary movements of the phenomenon all at once. Inclusive of reflecting on alphabets in art and also links to a medial communication. The second part of the diploma dissertation reacts to the strongest and the most inspiring moments. It focuses on a practical applications for art lessons. The third part [artistic] takes advantage of media knowledges and art lessons. They are interfaced into an interactive teaching material which challenges students to an active perception of visual culture.

Education for patriotism in Czech schools
Kyzlinková, Marcela ; Stará, Jana (advisor) ; Uhlířová, Jana (referee)
The key aim of this work is a method of patriotic education in our schools, mainly in the first grade of primary schools. The point of this work is to awaken patriotism in society again. In the first step we are informed about the important ideas that enable to develope the assumptions neccesary for the patriotic recognition and for an increase in patriotic feeling. The theory pays the attention to morality, influencing behaviour; for example, material and physical values and the aesthetic. It describes each historical term individually, from the beginning of national recovery during the first half of 19th century to the present days. It underlines the need to understand correctly the individual ideas and it points out the general chaos and risks of their interpretations in society. It recognises the important tasks that our society has to face to maintain the education of patriotism succesfully. The practical aspect contains the class discussions, interwiews and analysis of individual pupils, teachers, directors and it compares the level and quality of class debats with teacher`s attitude. The main thing was to find out the teachers' personal feeling about patriotism, his or her attitude towards its education and the way he or she communicates this during the lessons.

Happiness in the Elderly
Poláková, Anna ; Ondrušová, Jiřina (advisor) ; Krahulcová, Beáta (referee)
This diploma thesis is focused on happiness in the elderly. It searches answers on questions like: Can be the senior citizens happy? How should we grow old without loosing contentment? The meaning of the word happiness is discussed, as well as multiple points of view on old age. The presence of happiness in elderly is studied including ways toward the happiness. The thesis also includes seven casuistry, which illustrate the happiness of senior citizens. The results of casuistry complement the theoretical parts of the work.

Visual experince as example and pattern in relation to the expansion and influence into human life
Nohejl, Jiří ; Czumalo, Vladimír (advisor) ; Vojtěchovský, Miroslav (referee)
The main theme of this dissertation is to define an image as a visual experience. The human interaction is described by the author himself as a perception of the image, which serves as an information unit that could be presented as a possibility, example and pattern for the individual. There is an emphasis on the process of perception itself and on the way of interaction of an individual emphasizing the context of social learning and imitation in this text. The analysis of the principles of this interaction leading into introduction of the partial interactive models covering these processes is formed by the essential plane. The structure of the thesis is divided into ten main chapters in which the author tries to introduce a category of perception, a definition of the image and imitation as a tool of cultural transmission, presentation of the units of this transmission, the process of the interaction itself and analogous example of the fundamental role that a person in this interaction holds. There are also three analogies of these roles, which refer to the anthropological universal interaction describing the man as a gatherer and hunter. Their main purpose is to illustrate the form of a human experience better. Finally, there are reflections on the topic above. The possibilities and results, which...

Effects of pattern, size and background contrast of prey on discrimination learning in avian predators
Kuncová, Aneta ; Exnerová, Alice (advisor) ; Komárek, Stanislav (referee)
The topic of this master thesis was the effects of pattern, size and background contrast of prey on discrimination learning of avian predators. The aim of this study was to investigate the influence of selected components of warning coloration on aversive discrimination learning of avian predators of different age and sex. The choosen model organism was the Great tit (Parus major). The comparision was done between hand-reared naïve birds and wild-caught adults of different age and sex. The experiment was taking place in the experimental cage with one way mirror. The experiment used a design of simultaneous task with two pray which differed in one component of the coloration (pattern, size and background kontrast). The differencies in the ability of discrimination learning was found just between hand-rared naïve birds and wild-caught adults. Better results were shown by the wild-caught adults. The ability of discrimination learning of wild-caught adults was not influenced by the age and sex. Pattern was the only significant component of the warning coloration due to which the birds were able to memorise the discrimination task. Key words: avoidance learning, unpalatable prey, pattern, size, background, contrast

Evolutionary significance of visual traits of flowers and their influence on the pollinator constancy
Haveldová, Alice ; Štenc, Jakub (advisor) ; Klečka, Jan (referee)
Flower constancy is a behavior in which the pollinator visits flowers of the same plant species in a sequence more than would correspond to its preference for the given plant. This behavior is advantageous for plants because it can ensure efficient intraspecific pollen transfer which has a positive effect on their biological fitness. More efficient pollen transfer can lead to the selection of (visual and olfactory) flower traits that encourage flower constancy of pollinators. The main visual floral traits that affect constancy include colour, pattern, shape and size. However, these traits are of different importance for pollinators when they are deciding which flower to visit, and therefore their effect on flower constancy varies. The degree of flower constancy also differs between the functional groups of pollinators. Flower constancy is generally low in vertebrates, but insects and especially representatives of the order Hymenoptera are often flower constant.
