This thesis is focused on application samples with the inner insert used for Charpy impact test. This insert is welded to additional material by electron beam with pre-selected welded parameters. These parameters were chosen from data of performed experiments on homogenous welds. Resulting heterogenous weld was performed of evaluation of the microstructure, chemical composition and microhardness. Experimental materials were used austenitic steel 17 240 and ferritic steel 17 153 used on high-temperature applications.

The following monoethynylated N-benzylidene-2-hydroxyanilines were prepared: N-(4- ethynylbenzylidene)-2-hydroxyaniline, N-(3-ethynylbenzylidene)-2-hydroxyaniline, N-(4- ethynylbenzylidene)-2-hydroxy-5-nitroaniline and N-(3-ethynylbenzylidene)-2-hydroxy-5- nitroaniline, which differed in the position of the ethynyl group on the benzylidene ring and the substitution of the hydroxyaniline ring. Monoethynylated N-benzylidene-2- hydroxyanilines were used as the monomers for the chain-growth coordination homo- and copolymerization. The homopolymerization resulted in linear polyacetylene homopolymers with N-benzylidene-2-hydroxyaniline substituents. The copolymerization with multiethynylarene-type cross-linkers provided densely cross-linked copolymeric polyacetylene networks. The linear units of the networks carried N-benzylidene-2- hydroxyaniline substituents, the interconnection between the chains of the networks being realized by arene links. The texture parameters of the prepared networks significantly depended on the type of comonomers used. The highest specific surface area values (~530 m2 /g) were achieved with networks prepared by copolymerization of N-(4- ethynylbenzylidene)-2-hydroxyaniline or N-(3-ethynylbenzylidene)-2-hydroxyaniline,with 4,4'-diethynylbiphenyl used as a cross-linker.

The thesis titled The quality of life among hearing impaired people focuses on the current issue regarding the assessment of the quality of life in adult hearing impaired people in the Czech Republic. The conceptual basis of the submitted work is the current professional paradigm, with the emphasis on well-being in the lives of individuals with specific needs. The text deals with the multidimensional character of the concepts of the quality of life and the quality of life relating to health. It illuminates the subjective and the objective part of this broad and current concept. One theoretical chapter focuses on the area of hearing impairment in adult people in connection with the aspects which are bound to the quality of life in this part of the population. Mentioned are the personality traits of a hearing impaired person and the current social dilemma, which is connected to hearing loss, and is projected in the overall assesment of the quality of life of the people with this sensory handicap. One of the sub- chapters of this part of the text focuses on the key factors which influence the personal experience of life quality in the case of hearing loss. The research part of the work deals with method, continuation and assesment of the executed quantitative and qualitative research investigation. In...

The diploma work is focused on the development of prosocial behaviour in a kindergarten by means of reader's preliteracy. The theoretical part clarifies the terms related to the issues of the development of prosocial behaviour in a kindergarten, reader's literacy and preliterasy. It as well briefly describes the differences between heterogeneous and homogenous structure of the classroom in a kindergarten arranged according to the age and deals with the kindergarten as well as the classroom climate. The aim of the practical part was to describe in what matter the particular kindergarten develops pro-social behaviour of children with the support of reader's preliteracy. During the whole school year there were particular activities established and consequently implemented into an age-heterogeneous classroom located in a one-classroom kindergarten and upon consequent reflexion and feedback the activities were further provided with a possibility to work further with a given activity. To gain the reflexion and feedback the methods of interviews, monitoring and self-reflexion were used. Children participating in the activities kept developing their prosocial behaviour and attitude to reading. After studying specialised literature a questionnaire for the research within the practical part was designed for...

Teaching in groups is the organizational form of teaching. Students are divided into several groups and they cooperate to solve certain task. Mutual help and involvement of passive and diffident student is a big advantage. This form of teaching has disadvantages and several problems too. Teacher should arrange and prepare everything carefully. Teacher's role is different in this type of teaching. When teacher is planning, he should realize what he wants to achieve, how large groups will be appropriate, how to divide students into groups etc. Classical arrangement of class for frontal teaching is inappropriate for teaching in groups. In this form of teaching students should see each other. All groups can do the same work or each group can do a different work. Student assessment is a problem in this way of teaching too. Some teachers can not cope with this. Teaching in groups may not be always cooperative. Key words: activating form of teaching, teaching in groups, cooperative teaching, teaching in pair, heterogeneous group, homogeneous group, role in the group, cooperative skills

The study deals with mechanical characteristic of heterogeneous weld joint. The low carbon steel 22K and austenitic steel have been used as a experimetnal materials. The low carbon steel has special properties in basic condition. The sample has been evaluated in basic condition and after annealation. There have been evaluated impact of annealation proces to structure and mechanical charakteristics in experimental part of study. The particularised analysis of microstructure has been done by pictorial analysis. Mechanical characteristics has been examinated in both conditions by 2 different methods – measurment of microhardness according to Vickers and test of fracture toughness on compact tension specimens.

This work deals with Systems that combine automata and grammars. We investigate their properties compared with grammar systems and automaton systems. Work is focused on systems, which components are finite state automata, right linear grammars, pushdown automata or context free grammars. We also investigate usage of these systems in compilers.

A new type of organometallic polymer networks with a covalent structure of cross-linked substituted polyacetylenes containing Cu2+ or Pd2+ ions (5 to 17 wt%) has been developed. The metal ions were complexed in the networks predominantly with two N-salicylideneaniline ligands covalently bound to two different network monomeric units. Due to the chosen method of complexation, the metal ions have actively participated (as knots of the network) in the formation of cross-linked architecture of the products. For the preparation of organometallic networks two independent methods were used: (i) the direct polymerization of organometallic monomers and (ii) the two-stage method using postpolymerization introduction of metal ions into polyacetylene polymers containing covalently bound N-salicylideneaniline proligands. The starting low-molecular-weight blocks used for the network synthesis were new substances prepared within the framework of the diploma thesis, namely monomers of the mono- and diethynylated N-salicylideneanilines type and diethynylated organometallic monomers in which two molecules of a monoethynylated N-salicylideneaniline complexed one Mt2+ ion. The ethynylated monomers were polymerized to organometallic networks or precursors of these networks via chain-growth coordination polymerization,...

Résumé This thesis deals with finding differences between homogeneously and heterogeneously assorted classes in nursery schools and their influence on the readiness of a child to enter the first class in elementary school. The theoretical part focuses on school maturity and readiness, general characterization of a pre-school child before entering the first class in elementary school, differences between heterogeneously and homogeneously assorted classes in nursery schools and finally on a child's preparedness for the compulsory education. The practical part shows the results of a research carried out by the means of an author's test of school maturity method and a questionnaire. The research sample consisted of children of pre-school age before entering elementary schools from heterogeneous and homogeneous nursery school classes and pedagogues from nursery and elementary schools. The main objective of this research was to find out which children are better prepared for entering elementary school, whether from homogeneous or heterogeneous classes in nursery schools. The results of the research showed that children from homogeneous classes are prepared for entering elementary schools on the same level as children from heterogeneous classes, which leads to the conclusion that age composition of classes in...
