The thesis deals with the demographic progression in the Czech republic and consequences of population ageing. Teoretical part characterize basic concepts related to demography, ageing and the pension system and describe causes and consequences of population ageing. Analytical part is focused on period from 2005 to 2015. Process of population ageing is evalueted using selected indicators. Evaluation of progression population, age composition, average age, life expentancy and selected indices are part of thesis. Data relating to pension system are analyzed in the context of ageing population. Method of time series analysis was used for analysis and prediction selected indicators. The thesis contains suggestions and recommendations relating to the evalueted indicators.

The aim of this thesis was to evaluate the level of feeding habits of a selected human population segment in order to assess their understanding of issues related to nutrition and to basic components in their diet. For this purpose, a measuring instrument (a questionnaire) was designed. The first part contained questions related to respondent´s eating habits preferences, while the second part of questionnaire included questions examining the level of respondent?s nutritional awareness. In total 389 questionnaires were personally administered and completed by the respondents, under supervision of teachers. On the basis of the recorded answers it was found that, when purchasing food, the interviewed persons are governed mostly by the quality of it (37%). It was also discovered that, 40% of people preferred local foods to foods from abroad. Only 13% of respondents indicated their ?always or almost always? preference for ?bio foods?. It may also be said that, the three most popular dairy products are yoghurts (80%), milk (72%) and cheeses (72%), as opposed to fermented drinks (43%), which are the least consumed dairy products. Among the most popular meats the respondents included these three categories: chicken (83%), pork (73%) and beef (47%). The least favourite meat selected by respondents was mutton and lamb (35%). It was found that, 27% of the respondents follow information presented on food packaging but also that, 16% of the respondents do not follow packaging data, at all. According to the recorded frequency of occurrence the sum of correct answers can be said that most students answer 4 questions correctly. The recorded answer frequency counts show that most respondents answered correctly the following question: "What is bio food?" (94% of respondents). The worst answered individual question had to do with choosing foods with the highest ?Vitamin C? content, with only 7% being correct. On the basis of recorded answers it may be concluded that; the food consumption was influenced by the type of school which the respondents attended; as it appears related to the respondents´ age and their individual ability to decide on their food money spending. The questions that examined the level of information have shown that, the overall percentage of correct answers was increasing depending on the age of a respondent. The total percentage of correct answers kept increasing in relation to increasing age of respondents. No influence of gender on percentage totals of correct responses was demonstrated.

A breeding of seven European perch (Perca fluviatilis) groups of various origin was carried out under experimental conditions at 20°C temperature since the hatching of larval fish up till the age of 278 days, with intensive feeding using BioMar Inicio plus 0,55mm fodder with 15% fat content and BioMar Inicio plus 0,1mm fodder with 18% of fat content in later initial feeding. The average final weight of fish in the individual groups ranged between 79,4g and 27,63g. Mass yield statement (mass fraction of skinless filets, on the total mass), basic chemical analysis of filets (dry matter, crude protein, lipids and ash content) and organoleptic evaluation of musculature quality were carried out in the final stage of the growth test. No influence of the fish origin on the mass yield was detected. The average values ranged between 35,41% and 32,21%, but an influence of origin on crude protein content was discovered. The lowest values were determined in the population from the north of Germany 77,5% and the highest values on the contrary were determined in the population from the Štrbské Pleso lake 80,35%. The lowest lipids content was determined again in the population from the north of Germany 7,14%, while the highest fat content was detected in the population from Slovakia 8,66%. The results of organoleptic analysis didn't show substantial differences. Overall it can be stated that the monitoring didn't prove any substantial influences of fish origin on the parameters observed, which is confirmed by results of similar observations carried out by other authors e.g. with trout and carp.

Introduction Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease affecting the central nervous system. Although research on the diagnosis and treatment of this serious illness has made significant advances, the MS etiology remains unknown. Although there is still much to be found in the MS pathogenetic mechanisms, understanding the mechanisms of immune-mediated damage to the central nervous system (CNS) components of MS allows not only the introduction of new drugs that positively modulate inflammatory inflammation but also the understanding of immune- mediated diseases affecting the CNS in a broader sense. Methods The Ph.D. thesis is a general introduction followed by an annotated set of author's publications on proteomics, lymphocytic population in MS and disability. Study 1: Proteomic analysis of cerebrospinal fluid for relapsing-remitting multiple sclerosis and clinically isolated syndrome was conducted to find changes in the low molecular cerebrospinal fluid (CSF) segment and to determine what native peptides and how much they are in cerebrospinal fluid among patients with clinically isolated syndrome (CIS) and relapsing-MS (RR MS) compared to a healthy population. Study 2: Lymphocytes in the treatment with interferon beta-1b targeted individual...

The population of Common Kingfisher in northen part of Třeboňsko Region was monitored according to the fulfilling of EU directions {--} Natura2000. Between the years 2004 and 2006 105 km of watercourses, water reservoires, sand quarries in the map square 6854 were regularly monitored. Recent population condition was monitored. Technical adjustement of recent, new, and extinct nest walls followed. Thanks to these modifications, the number of successful and perspective breeding places increased. The next step was to check the progress and success of nesting. During other inspections I observed the success of nesting, depending on environmintal conditions, and{--}if needed- I determined the reason why the nest place was destroyed. In the conclusion I suggest practical measures {--} how to adjust nesting places {--} which night result in stabilization of the population.

Goal of this Thesis is the comparison of the Grayling˘s genetic diversity. The complete mitochondrial DNA (mtDNA) control region (1083 base pairs) and gene for cytochrom B (1076 base pairs) were sequenced in 147 European grayling (Thymallus thymallus), from 21 populations in Czech Republic, Slovakia and Bosnia. In samples, 17 haplotypes were detected with average haplotype diversity Hd = 0,5480 and genic differentiation (FST) from 0,001 to the 0.9341. The most common haplotype TH1 was detected in 92 samples. An inferred intraspecific phylogenetic tree revealed three well-separated clades. One clade was represented by Danubian haplotypes from Slovakia. Second highly divergent clade contained individuals from river Vrbas in Bosnia, and the last biggest clade included haplotypes of all three sea basins from Czech Republic. We suppose that the gained results will be later utilized to the choice of suitable conservation measures that will lead to stabilization of the state of ancestral population of this ever more rare species in our region.

Although the graying of the American society has been well documented, the question as to whether the elderly populace will indeed become a political factor has yet to be determined. Some studies indicate that the elderly will soon develop the consensus needed for political action; other studies counter that the elderly will never be a viable political factor. Among the determinants listed as influencing the political participation equation are standard socioeconomic variables (e.g., race, social status, education, and income). These factors have been studied extensively (Campbell 1960; Key 1950; Milbrath 1965; Nagel 1987; Rose 1965). Trela recently added an item that could possibly influence the political activism of the elderly: membership in age-graded associations. This study addresses the questions raised by Trela (1971), namely, whether age-graded associations influence the political activity of senior citizens, and if so, in what direction elderly participation is swayed. Unlike previous reports, the preliminary data gathered for this study suggest that the age-graded associations of the elderly cannot accurately predict their political activism.

On the basis of a complex demographic analysis the thesis defines the areas in South Bohemia, where is apparent a specific development of demographic indicators and tries to find the main causes and consequences of these differences. From the perspective of the demographic indicators state the position of the South Bohemian Region is compared with other regions in the Czech Republic. On the basis of the demographic analysis is created a SWOT analysis of demographic trends of the South Bohemia population. In the final section there are explored impacts of demographic trends on the provision of social services for elderly and impacts on education and medical system in response to changes in the demographic structure of the population of the South Bohemia Region.

Thesis evaluates sustainability of economic growth in current conditions from three main points of view: impacts of mankind to enviroment especially in form of global warming, growth of human population and availability of energy sources. Thesis offers possible scenario of solving the situation and analyses, how had situation been solved till now and tries to find reasons why were these solutions succesfull or not, and proposes possibilities to solve the situation.
