This thesis is focused on assessing the impact of weather changes on the performance and economics of grazing cattle in the border areas of south Bohemia. The aim of the study was to compare the progress of meteorological parameters observed in three years and put them into the context of the economy of livestock production. In the actual experimental part I focused on the search and processing of data for calculation of economic indicators and processing of meteorological data that provided me with the department of landscape management.

The thesis deals with the content of selected phenolic compounds in some species of the genus Amaranthus, in black elderberry (Sambucus nigra L.) and buckwheat (Fagopyrum esculentum M.). Phenolic compounds are a group of natural compounds exclusively vegetable character. Flavonoids represent only one group of phenolic compounds. Flavonoids show many positive biological effects, in particular act as antioxidants. Natural flavonoids may cause to prevent from coronary- heard diseases and other diseases associated with older age. In recent years the increased attention is paid to flavonoid investigation due to its biological effects. For the determination of phenolic substances there were used two independent analytical methods. There are the high-performance liquid chromatography (HPLC) and micellar electrokinetic capillary chromatography (MECC). The MECC method was used for determination rutin and free quercetin. The highest content of rutin was found in leaves of buckwheat (76,400 mg/kg of dry weight) and the lowest content of rutin was determined in buckwheat hulls. The highest content of rutin was observed in teas from buckwheat leaves and inflorescence. This amount of rutin corresponds with rutin content in more than two pills of Ascorutin (the most favourite flavonoid medicament in the Czech Republic) The HPLC method was used for quantitative determination of phenolic acids. The content of free quercetin was monitored in all samples. No free quercetin was found both in plant material and in samples of teas. The ethanolic extract from the elderberry inflorescence didn´t contain any free quercetin. Free quercetin wasn?t found in any further samples of teas, which were prepared by described methods.

The aim of this work is to identify development income tax burden as a result of changes in laws and amount of income for the selected type of household, divided by income groups within five years. The work is divided into two parts ? thoretical and practical. The theoretical part discribes the basic concpets regarding the division of family, the subsistence minimum and the average wages. Also includes information about the natural person income tax. The practical part includes a description of the selected type of household (family without children in the four income situations) and own calculations of tax liability this family within five years.

The study focuses on social work as work with values. In the theoretical part defines the concept of value. Values are later described in social work, families and shelters for mothers with children. As part of the research the values of shelters for mothers and children and the value of users of these facilities are then compared to each other, to what extent are the same or different. The research was conducted in three shelters for mothers with children through interviews. By document analysis the values of shelters on the quality standards of social services were measured. The questions used in the interviews are divided into several areas: family relationships, the relationship of mother and education and work in childhood and adulthood, the relationship of a mother to her children, their education and future occupation, partner relationships and additional questions. These areas should point out what is important to mothers and children. Using this information is possible to compare the values and social workers in shelters that social workers can be incorporated into the concept of the social services.

One billion of people lives less than one dollar a day, millions of people are forced to live out of their home, problems of humanitarian aid are very pressing theme. This diploma thesis aims to create a didactit unit for students of medical school, which would deepen their knowledges and influence their attitudes to humanitarian aid. At first at theoretic part the space is focused on complete overview in humanitarian aid, starting on history, current strategy of humanitarian aid, individual participants of aid, over the rules and risk, up to ethic and legal anchoring of aid. In theoretic part is giving a description in brief of three non- governmental non-profitable organization, whose are engaging in humanitarian aid (International Movement of Red Cross and Red Crescent Societies, Docktors without Borders known as Medecins Sans Frontieres, which is devoted more space in view of the fact that students'orientation and Czech organization People in Trouble). In research part the questionnaire survey is performed in chosen medical school, which inquires the basic knowledges of humanitarian aid and three chosen non-profit organization and monitors students'attitudes to given problems. The didactic unit is created in the basis of analysis of collected data. From the questionnaire survey is clear the...

Homeless hostels started being established on the territory of the Czech Republic in the beginning of 1990. At present they are institutions of social services providing persons in unfavourable social situation related with loss of dwelling with accommodation services of social prevention for transition period. The goal of the thesis was to characterize the homeless hostel for men as an institution helping homeless persons with social integration from the point of view of professional staff and to explain life fates and experiences of selected users. The work is conceived as quality research focused primarily on the issues of social work. In order to meet the aim, the following methods and techniques of data collection were used: interview with help of instruction, narrative interview, study of documents and observation. Rules of service provision, internal rules of the institution, social worker activities, course of service and its planning are specified in more detail on the base of the data from interviews with professional staff and their subsequent analysis. The work focuses also on the offer of activities with stress on possibilities of work rehabilitation of the users and compares the individual facilities according to specified criteria. Life experiences of selected users before they stay in the homeless hostel are described together with their expectancies and future plans. Two hypotheses were formulated on the base of the research.

This thesis focuses on the public opinion on single mothers in emergency conditions in Český Krumlov region. The theoretical part defines single mother and single parent family. The fact that in many European countries the numbers of single parent families is increasing is stressed out. The theoretical part describes the changes in models of family behavior have been experienced in the last decades and factors which influence them. Also, basic facts on single families in the Czech Republic are presented e.g. female or male single parent family, their age, reasons for single family, social status, numbers and percentage of children born to single parents within last twenty years etc. In addition particular reasons of becoming a single mother are explained e.g. divorce, single parenting, becoming a widow. A phenomenon of domestic violence is closely related to the subject of single mother, therefore it is dealt with here too. The theoretical part conclusion shows principal reasons which cause that single mothers get into emergency conditions. The practical part presents a research which focuses on public opinions on single mothers in emergency conditions in Český Krumlov region. The field research was conducted through the method of a questionnaire. The focus group was public in Český Krumlov region. The aim of the field research was to map public opinions of Český Krumlov region residents on single mothers in emergency conditions. The research showed that single parent (mother) families are considered to be a group with the highest risks to be exposed to low standard of living. At the same time more than 50 % or respondents think that the most obvious reason for single mother to be in a critical life situation are economic troubles and lack of finance. An important fact which contributed to this result is that more than one quarter of respondents thinks that their current economic situation is not easy or even critical. In respect to domestic violence issue, the research showed that more than half of respondents believe that domestic violence against women by their spouses is mainly a results men aggressive behavior. The most frequent answer picked was aggressiveness initiated by the use of alcohol and drugs, than aggressive behavior inborn i.e. genetic predisposition to act aggressively and aggressive conduct like a way how to escape and resolve life situations which may appear to be unsolvable and an aggressor is not able to control her behavior. Public sees domestic violence to be a serious problem which is mainly present in single mother families. The most of respondents believe that domestic violence against mothers and children is the most frequent reason for single mothers to apply for subsidized single parent accommodation. The results also show that more than 60 % of respondents understand what domestic violence is and that very often victims never tell anyone and keep it secret even though they suffer for years. It is assumed that in this respect, public sees the relation between domestic violence and torturing victims in early childhood. More than 60 % of respondents believe that prevailing numbers of women who are victims of domestic violence in their childhood are victims of domestic violence also when they grow up mainly because of their previous experience when low self-confidence and violence become a part of their daily life even though hard bearing.

The aim of this thesis is to provide a comprehensive overview of the main approaches to modeling data loaded with redundant zeros. There are three main subclasses of zero modified models (ZMM) described here - zero inflated models (the main focus lies on models of this subclass), zero truncated models and hurdle models. Models of each subclass are defined and then a construction of maximum likelihood estimates of regression coefficients is described. ZMM models are mostly based on Poisson or negative binomial type 2 distribution (NB2). In this work, author has extended the theory to ZIM models generally based on any discrete distributions of exponential type. There is described a construction of MLE of regression coefficients of theese models, too. Just few of present works are interested in ZIM models based on negative binomial type 1 distribution (NB1). This distribution is not of exponential type therefore a common method of MLE construction in ZIM models cannot be used here. In this work provides modification of this method using quasi-likelihood method. There are two simulation studies concluding the work. 1

The Diploma thesis the Preventation of the extreme social exclusion is focused on the issue of the long-term homelessness. Using available literature it tries to find information explaining the consequences of the depressive life condition in the form of the extreme social exclusion and life without any home. Furthermore the thesis is focused on the homelessness as a multifactorial pathological phenomenon. The Diploma thesis is therefore focused on the specific terms, facts and consequences connected with the condition of the long-term homelessness. The theoretical part is concentrated on the study of the human needs based on the humanistic conception of a personality and Maslow's hierarchy of needs. Moreover the text describes the methods of the help during the social work with the homeless people and introduces social services according to the monitoring of the needs of the people in the long- term social exclusion. Another part of the thesis is dedicated to the social services in the capital city Prague. The practical part is focused on the needs of the homeless people. The needs and the applicability of the available social services were inquired with the means of interviews, studies of the documentation and observing in the community of homeless people.

Médecins Sans Frontières is one of the most respected humanitarian organisations in the world, they focus mainly on providing medical care in places of emergency and war. These places are also interesting for journalists who can take advantage of the protection on the missions while also acquiring unique stories. Working in conflicted areas under a protection of an organisation is called embedded journalism. This concept has been until now studied in connection with army when journalists travel with soldiers. Therefore, their view of war can be distorted. However, a journalist who travels with Médecins Sans Frontières may also have a distorted view of world. Twelve journalists from around the world, who visited the missions and documented the work of doctors, gave interviews for this diploma thesis. In the interviews, they described their experiences, the advantages and disadvantages of being embedded, and how the organisation may have influenced their work. Several Médecins Sans Frontières workers have also shared their experience. The interviews were put in context by a content analysis that focused on the articles and photographs made on missions by these journalists.
