Structural and morphological characterization of polyamide buckles
Kubíčková, Eva ; Poláček, Petr (referee) ; Bálková, Radka (advisor)
The work deals with structrural and morphological characterization of polyamide buckles used to fasten webbins. The buckles were produced in five different years, a few of those produced in 2000 and 2004 were broken. The aime is to determine the type of polyamide and the cause of fracture of the buckles during using. The buckles were characterized in terms of structure and composition by Fourier-transform infrared spectroscopy in a mode of attenuated total reflaction, differential scanning calorimetry, thermogravimetry and X-ray diffraction. The buckles were made of polyamide 12. The broken buckles showed higher melting point, lower thermal stability and, in addition to modification it also contains modification, which is more fragile and probably represents the cause of fracture.

Molecular modelling – structure and properties of cyclic esters and carbonates
Kubíčková, Eva ; Pilátová, Ivana (referee) ; Richtera, Lukáš (advisor)
Molecular modelling enable to predict the behavior and assist to interpret experimental data. The aim of our study was the prediction of selected properties of cyclic esters and prediction of their structures. The visualization of selected molecular orbitals and electrostatic potential-mapped electron density surface was made. Subsequently, bond distances and bond angles of selected cyclic esters were obtained. Factors affecting the ring-opening polymerization of cyclic esters were studied with usage of these data. The thermodynamic factors influencing the ability of polymerization were studied for series of lactones of different ring sizes. Study of these factors helps to estimate the behavior and the ability of these compounds to polymerize.

Education of Roma children in elementary education system in the Czech Republic.
KUBÍČKOVÁ, Eva
This diploma thesis deals with a topic of Roma education in the Czech elementary education system. Aim of the thesis is to analyse current state of czech educational system in a relationship to Roma students, to point out the practice of segregation at elementary schools and to offer possible solutions. In the theoretical part there is a description of current situation of Roma minority in the Czech Republic. Through media information and proffesional papers I reflect escalated social situation and analyze most frequent disputes between Roma minority and majority. I present a reform of Roma children education as one of the priorities for Roma integration in the Czech Republic. I present current alternatives of elementary education of Roma students in the Czech republic and compare advatages of inclusion against segregation in education. The practical part focuses on didactical arrangments of multicultural education topics in 6. ? 9. grade. Educational project called ?Black sheep, white crows? is a realization of cross-sectional topic of multicultural education in civics and czech language. Focus of this educational project is to verify the functioning of education at an open elementary school, which uses inclusive education.

Diagnosis of Chosen Didactic Concepts in Semantic Space of Students of Teaching and Primary School Teachers
KUBÍČKOVÁ, Eva
This diploma work raises the issues and subsequently the diagnostics of preconcepts for didactic concepts of students of teaching and primary school teachers. The aim of this work was to find out to what extent the perception of some chosen didactic concepts are related comparing students of pedagogical faculty and primary school teachers. The theoretical part aims to the technical definition of the semantic differential research method and definition of the concepts involved in the research. In the practical part the data relating to chosen didactic concepts were found and processed by method of semantic differential.
