The topic of this diploma thesis is Alternative lifestyle as a form of content human existence. This thesis is focused on specification of subculture and I defined the subculture of homeless people, which as I assumed and also as my own research data showed, can demonstrate the content form of human existence. The theoretical part of this thesis is divided into four chapters. The first chapter constitutes a theoretical scope of this thesis where I put emphasis on social norms and theory of social deviation, which are crucial for homeless people who are demonstrating alternative lifestyle which is significantly different from the lifestyle of mainstream conformist society. Second chapter describes characteristics of homelessness. The third chapter includes procedure of help to homeless people in their life situation. There are also stated social services for homeless people. The last chapter is focused on the alternative lifestyle. I also deal with the topic of voluntary homelessness. The aim of this diploma thesis is description of aspects of lifestyle of the observed subculture of homeless people. The target group consists of 20 homeless people in age from 18 to 70 years. A method of qualitative approach was applied and a method of analysis of case studies was used for data collection. The main technique of data collection was an interview with directions which I used with 10 homeless people who were in asylum house and with 10 homeless people who were present directly at the public areas. In the context of this thesis five research questions were determined. The primary data was coded/indexed and then processed with the framework analysis according to Ritchie and Spencer. The outcomes of the research showed that the most frequent reason for the origin of homelessness is alcohol addiction. Most frequently it is related to single or divorced man and women. The daily regime of homeless people is from a greater half regular. Among the most frequent daily activities in the asylum house can be mentioned watching television, cleaning common areas of the asylum house, fixed activities and drinking coffee. The outdoor activities mostly constitute of collection of metal, cooking, shopping for food and searching the garbage bins. They usually spend winter nights in facilities of social services (doss house, asylum house), in a tent, in makeshift shanties, or in a squat. Most people spend their days with their friends or partners. People who live in public areas are more willing to make some extra money. There was three times higher experience with begging of the people who live in public areas than people who live in asylum houses. People in asylum houses usually pay for day board meals. People who live outside in public areas procure their food in supermarkets, day centres and doss houses and in garbage bins. For homeless people nicotine addiction is more frequent than alcohol addiction. They perform their personal hygiene in the facilities of social services (day centre, doss house, asylum house). They usually get their clothes from social or asylum clothes supplies. They do not live in relationships with partners however people who live in the public areas have more sexual contacts. More than half of respondents do not think about their future. People who live in asylum houses are more satisfied with their life situation, nevertheless more than half of respondents would like to change their life situation. On basis of the results of this research theoretical concepts were induced.

The aim of work was comparing breeding of suckler cows in agriculture companies with different methods of farming. Both farms are in the same climate conditions in submontaine region in Blanský Les. I included a herd of cows {--} bred Aberdeen Argus from the conventionally company and crossbreeds (the higher blood percentage of race Aberdeen Argus) are at the ecological farm. In both farms was checked same indices (reproduction inbreed, health problems cows and calves, management herd, sustenance, grazing system and economy of breed). Data was assessed behind period two years 2005 and 2006.

The diploma thesis is divided into three parts: cattle herd management, ethology and economic evaluation. The observation was carried out on the farm which is situated in the mountain region of Šumava mountain with decreasing agricultural production. The main production is cattle breeding without market milk production. These meat breeds (Hereford, Aberdeen angus, Charolais) are bred there.

This paper examines the importance of communication for people with visual impairments. Communication is a basic human needs and information is its tool, whose shortage may occur when eyesight is damaged or lost. The beginning of the paper introduces the basic concepts associated with visual impairment and it also presents a historical overview of the issue. The importance of communication intertwines through the following chapters, based on a general description of communication but also its division into non-verbal and verbal communication that is divided into spoken, written and computer-aided communication, with a focus on speech input and output, and other forms of communication. The paper also describes the functions of communication and communication in various fields such as in teaching and working processes, in health care, but also in communication with a social worker. The theoretical part is concluded with a brief mention of communication of people with hearing and speech impediments. The objective of the practical part is to map the views of visually impaired people on the importance of communication in their lives, while finding the most common ways of mediated communication not only in people with visual impairments but also in those without visual impairment. For this purpose, a research, which is further evaluated and discussed in the following chapters, was created. Seven case studies of people with visual impairments, focusing on the history of their visual impairment and on communication, were also elaborated in detail. This paper can be used in TyphloCentres and this paper may also serve to a wide professional public who encounter visual-impaired people during their work.

This thesis - The issue of homelessness women: Social work at the shelter for women deals with the issue of homelessness for women and more women using homeless through social work in a particular social service - a shelter for women. The theoretical part describes the basic concepts related to homelessness; characteristics of homelessness; forms of homelessness; homelessness for women - causes and circumstances that led to the loss of home; forms of assistance; inclusion in housing and society; social work in shelter for women - services targets; concrete assistance and cooperation of social worker with clients; roles and responsibilities of social workers; pitfalls of social work at the shelter for women. The practical part contains stories (case studies) clients shelter for women who not only illustrate the combination of the various causes of loss of home and homelessness of these women, but also how to work with them through social work.

The diploma thesis deals with the position of error in the teaching of mathematics in the awareness of pupils and teachers. It also focuses on the responses of pupils and teachers to errors. Main attention is paid to mathematical errors. The thesis consists of two parts, theoretical and practical. The theoretical part contains an overview of selected error views. It contains a look at the development and changes of views on the concept of "error", the different concepts of error classification and pedagogical and psychological views on the term "error". The practical part is based on the research carried out at the 2nd level of two primary schools in Prague and Neratovice. Pupils filled in a questionnaire and a guided interview was conducted with teachers. KEYWORDS work with error, error classification, causes of errors, learning without errors, learning with error

The diploma thesis focuses on issuance of the primary bond by non-financial companies on the Prague Stock Exchange (PSE). In the theoretical part were described the main parameters of securities and financial indicators of companies that build the risk premium and discussed options of risk-free base. The application part presents the evaluation of major factors influencing price and bond rates on the example of emissions carried on the PSE.

The thesis deals with the analysis of the clustering and mapping techniques derived from the principles of the neural and statistical learning and growth theory. The selected branch of the unsupervised bio-inspired prototype-based models is described in terms of the proposed logical framework, which highlights the continuity of these methods with the classical "pure" statistical methods. Moreover, as those methods are broadly understood as the "black boxes" with the unpredictable, unclear and especially hidden behavior, the examples of the spatial computational and organizational patterns in two-dimensional space are provided. Additionally, this thesis presents the novel concept based on the non-linear, non-Gaussian Gompertzian function, which has been widely used as the universal law in dynamic growth models, but has not yet been applied in the field of computational intelligence. The essence of Gompertzian dynamics is mathematically analyzed and a novel simple version of the Gompertzian normalized function is introduced. Furthermore, the function was modified for use in the field of artificial intelligence and neural implications were discussed. Additionally, the novel neural networks were proposed and derived from the topological principles of Kohonen's self-organizing maps and neural gas algorithm. The Gompertzian networks were evaluated using several indicators for various generated and real datasets. Gompertzian neural networks with fixed grid and integrated neighborhood ranking principle generally show lower mean squared errors than the original SOM algorithms. Likewise, the unconstrained Gompertzian networks have demonstrated overall low error rates comparable to neural gas algorithm, more stable and lower error solutions than the k- means sequential procedure. In conclusion, the Gompertzian function has been shown to be a viable concept and an effective computational tool for multidimensional data analysis.

The intended work examines how the relationship between the unaccompanied migrants and the hosts is formed within foster care. Foster care could be defined as "long-term and repetitive contacts," where specific forms of relationship are negotiated between individual actors. I ask what activities and practices the actors make significant concerning the arrival, what ideas and imaginations on the part of the actors enter into the relationship, and how emotional rules are negotiated in a relationship. Last but not least, the work examines how the individual actors relate to the category of unaccompanied minors, that is, how this category, which has its legal definition, is negotiated. Key words: unaccompanied minors, foster care, family practices, emotional work, reflexivity

This master’s thesis deals with the issue of damage of the vehicle’s drivetrain due to the operating fluid leakage. The aim of the thesis is to clarify the severity of this type of damage and, alternatively, the times during which these failures can occur. The theoretical part describes the issues of lubrication and cooling systems, including the consequences of sub-optimal operating conditions. The evaluation is based on conducted experiments and is compared with already published tests. The parts that are most often damaged are also described. Finally, the recommendations for lowering the extent of damage are formulated.
