History of vegetational development in the Cheb basin from sedimentary record of the SOOS National Nature Reserve
Suda, Tomáš ; Kuneš, Petr (advisor) ; Bešta, Tomáš (referee)
Vegetation development in the Cheb basin ( W Czech Republic) recorded in the sediments of the SOOS ational ature Reserve This thesis focuses on palaeoecological research of quaternary sediments in the Soos National Nature Reserve (Cheb basin, NW Czech Republic). Quaternary history of this locality is poorly known, despite it is a valuable and protected area with high natural qualities. The Soos basin is also known for its unique geological record, which is expected to cover information on landscape dynamics at least during the Holocene. A lake existed in the Soos basin enabling accumulation of diatomite and peat sediments of a broad palaeoecological potential. Records were analysed with method of pollen analysis and were dated using 14C. The results of this study bring information about vegetation development in the area of Cheb basin as well as development of lake ecosystem. It also gives a new insight on lake's origin and its age. The accumulation of peat sediments started in the Preboreal period and was continuous at least until the Atlantic following with a hiatus, therefore further detection of vegetation development is impossible. The beginning of diatomite accumulation, as well as the existence of the lake goes back to the Bølling interstadial, according to radiocarbon dating. However, this...

The tax system reduces motivation to return to work among mothers with young children: recommendations and evaluation
Šatava, Jiří
In the Czech Republic, the overall taxation of work, i.e individuals' income tax together with social security and health insurance contributions, places a heavy burden even on the relatively low earnings of so-called second earners in households, i.e. partners with lower earnings. These peoples' work activity is, however, generally very sensitive to the level of taxation. A large group of these earners is made up of mothers with young children. Mothers who are the second earner in their household are subject to a participation tax rate (PTR) up to 30 % higher than their partners, and yet a higher PTR results in lower motivation to work. Women with children and low earning potential are subjected to the highest PTRs in comparison with their partners.

Social Activation Programs for Seniors from the Perspective of Social Workers
HAMERNÍKOVÁ, Lada
This Bachelor thesis entitled Social Activation Programs for Seniors from the Perspective of Social Workers mainly deals with the issue of social activation programs that are provided to seniors in residential facilities. The main objective is to ascertain the views of social workers on these programs. There are set two main research questions in the Bachelor thesis. The first one deals with the practicality and quality of activation programs for seniors, the second research question examines the opinion of social workers, whether the social activation programs are used by seniors. The theoretical part describes the current situation related to aging, engaged in gerontology, biological, psychological and social manifestations of aging, preparing for retirement, communication with the elderly, seniors' quality of life, social exclusion of older people, further discusses the services provided to the elderly , the role of social workers in residential facilities, individual planning, active aging, activation programs for seniors. It was chosen the qualitative research method through semi-structured interviews with the social workers in selected residential social services for the empirical part. It was set five basic questions and one additional question regarding to social activation programs for the interview. The results of the work showed that social activation programs for the elderly in residential facilities are from the perspective of social workers very beneficial, efficient, high-quality, relevant, they are used by seniors and improve the quality of life for seniors. The results of this Bachelor thesis can be used to improve the quality and the numbers of activation programs which are offered to seniors in residential facilities.

Introduction to bio art
Šperanda, Nina ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
Bio art is a contemporary art practice that works with living organisms (except humans) or is created in cooperation with living organisms. It is relatively new art movement that is rooted deeply inside the history of evolution, domestication of animals and plants, technological discoveries, their development and science. Never before was art questioning its ethics and aesthetics in such profound, molecular and sub-molecular way.
In this work I will consider the historical influences and conditions that led to current developments in the field. I will also try to explain the problematics of defining what bio art is and try to clarify the associated terminology. Most relevant and ground breaking works in the field will be mentioned as some new recent developments.
Aesthetics of bio art is also an important subject often set aside by the ado around ethics of it. It is an extremely important subject to be considered when talking about bio art and I will try to sketch out a brief outline of it with references to philosophy and contemporary bio art theory.

Nutrition of pregnant - reccomendation and reality
FAJMONOVÁ, Simona
For my bachelor thesis I have chosen the theme : Nutrition of pregnant women recommendations and reality. The theoretical part includes the specifics of nutrition in preconception period and pregnancy, risk groups of pregnant women, high-risk behavior and a chapter about dietary supplementation in pregnancy. Pregnancy is an important period in a woman's life. The changes that accompany pregnancy also impose increased demands on the supply of the body with nutrients. I have chosen the method of a survey for the processing of the research part of my thesis. The practical part includes the results of the survey, which was attended by 80 women in the 7th-9th month of pregnancy. The questionnaire asked for basic information besides the weight, height and weight gain in pregnancy, also eating habits, fluid intake, inadequate habits (alcohol, smoking), use of dietary supplements, awareness of pregnant women and their physical activity. The questionnaires were processed in Microsoft Excel using tables and graphs. All collected pieces of information about dietary habits were compared with the recommendations for pregnant women. The aim of this thesis was to find out what is the reality of eating habits of pregnant women compared with recommendations. Another aim was to determine, whether pregnant women are well informed about the nutrition recommendations during their pregnancy and where they get the information from. Further aim was to explore, whether pregnant women use nutritional supplements before or during pregnancy and what kind of them. The last aim was to determine some of the bad habits during pregnancy (e.g. alcohol , smoking). The results of the questionnaire survey showed that by the majority of pregnant women the reality and recommendations coincided in water intake and beverage preference. Most of them preferred water or tea. Coffee consumption was also by the majority of them problem-free. Eating meat and eggs corresponded with the recommendations for a large group of respondents. As for legumes, fish and fish products, their consumption corresponded with the recommendations by only about half of the women. Eating fruits and vegetables were in the majority of pregnant women unfortunately insufficient as well as the consumption of milk and dairy products, nuts and seeds. It would be very appropriate to increase consumption of these groups of food. Conversely, the consumption of sausages and sweets, which turned out to be more frequent, should be reduced . Most women were well informed about the nutrition recommendations during their pregnancy, in most cases from the media or pregnancy counseling from a doctor. Here, I would suggest creating a website for pregnant women offering really reliable information. Nutritional supplements related to pregnancy were used by about half of the respondents. Only less than a half of the surveyed women supplemented folic acid in preconception period. I would suggest to create some information leaflets about the suitability of folic acid supplementation in preconception period and place them in the gynecological outpatient's clinics . Pregnant women ordinarily didn't smoke and consume alcohol. Occasional alcohol consumption stated 14 % of women. It seems that women are informed enough about the risk of smoking and alcohol consumption.

Evaluation of the effectiveness of teaching vocational subjects depending on physical activity before schooling.
Janošíková, Martina ; Hanušová, Marie (advisor)
The period of transition to secondary school brings substantial changes in the requirements for study obligations, autonomy, communication, expression, or separated from their families in the form of staying at the dormitory. Students enrolled in sport centers, in addition to these changes, still struggling with the responsibilities associated with sport. Because they are students first through fourth grades of secondary schools and secondary vocational schools, an age when image self-I am, what I believe in, arises in interactions with the outside world and their own experience, plays a very important role to influence the environment, educators, teachers and trainers, with which students spend most of their time in practice. This study looks at students comprehensively in terms of personal development as a multifactorial biopsychosocial unit, in terms of cognitive and motivational processes, states and properties from the perspective of social psychology dealing with the interactions, relationships and communication, psychology of individuals within the social group and its importance for the development of the individual . It monitors conditions and educational outcomes in terms of educational psychology, dealing with forming properties, opinions, attitudes and value orientation from the perspective of educational psychology.

Influence of meadow management on the migration behavior of selected species of butterflies
Bubová, Terezie ; Langrová, Iva (advisor) ; Farkač, Jan (referee)
Migrations are the key process and one of the basic biological features, which allow survival of endangered species in fragmented landscape. In the last decades, agriculture intensification, industry and urbanization caused that number of natural butterfly habitats has significantly decreased. The localities originally suitable for butterflies are currnetly converted to farmland or building plots. This PhD thesis aimed to find a compromise solution of meadow management, which should allow a commercial use and concurrently do not jeopardize the continued existence of endangered or threatened species. The main idea of this study was in the intentional emigration causing in the middle of flight period, which should lead into resettlement of the population to another (potentially more suitable) locality. Possibility of aimed manipulation with butterfly emigrations would be considered as a major breakthrough in their protection.
The investigated species Phengaris nausithous (Bergsträsser, 1779) and Phengaris teleius (Bergsträsser, 1779) are both considered to be flagship species for protection of European butterflies at open meadows. This study is based on research, which was carried out in 2013-2015 at 17 patch in localities Dolní Labe, Czech Republic. In above mentioned years, one selected meadow was mowed in the middle of flight season and the emigrations were then monitored using mark-release-recapture method. Results of population and migration characteristics were calculated in MARK 8.1 software. Subsequently, the effect of mowing on emigration (comparison of emigrations from the meadow before and after mowing) was evaluated using Statistica 13.
The hypotheses of this study were based on the assumption, that the loss of resources after well-timed mowing should increase the activity of adult butterflies. During the monitoring, number of emigrations was increased only in flight season 2015. Unfortunately, the statistical evaluation did not show significant effect of mowing on migrations. On the other hand, the hypothesis dealing with colonization of nearest meadows was confirmed.
Effect of intentional emigration caused by management interventions was unfortunately not proved. However, we found out, that even though the population at one mowed meadow decreased clearly, the metapopulation size at the locality remained more or less stable.
At investigated (mowed) meadow, there was observed a sharp decline of P. nausithous abundance. On the other hand, P. teleius population was only slightly reduced. It is therefore conceivable, that P. teleius are not as susceptible to innapropriate term of mowing. The results obtained in our research conclusively displayed no possible positive effect of mowing in the middle of flight season and a necessity of suitable management maintenance at localities inhabited by Phengaris butterflies.

Noise, Transport and Structural Properties of High Energy Radiation Detectors Based on CdTe
Šik, Ondřej ; Lazar, Josef (referee) ; Navrátil, Vladislav (referee) ; Grmela, Lubomír (advisor)
Poptávka ze strany vesmírného výzkumu, zdravotnictví a bezpečnostního průmyslu způsobila v posledních letech zvýšený zájem o vývoj materiálů pro detekci a zobrazování vysokoenergetického záření. CdTe a jeho slitina CdZnTe. jsou polovodiče umožnují detekci záření o energiích v rozsahu 10 keV až 500 keV. Šířka zakázaného pásma u CdTe / CdZnTe je 1.46 -1.6 eV, což umožňuje produkci krystalů o vysoké rezistivitě (10^10-10^11 cm), která je dostačující pro použití CdTe / CdZnTe při pokojové teplotě. V mé práci byly zkoumány detektory CdTe/CdZnTe v různých stádiích jejich poruchovosti. Byly použity velmi kvalitní spektroskopické detektory, materiál s nižší rezistivitou a výraznou polarizací, detektory s asymetrií elektrických parametrů kontaktů a teplotně degenerované vzorky. Z výsledků analýzy nízkofrekvenčního šumu je patrný obecný závěr, že zvýšená koncentrace defektů způsobí změnu povahy původně monotónního spektra typu 1/f na spektrum s výrazným vlivem generačně-rekombinačních procesů. Další výrazná vlastnost degenerovaných detektorů a detektorů nižší kvality je nárůst spektrální hustoty šumu typu 1/f se vzrůstajícím napájecím napětí se směrnicí výrazně vyšší než 2. Strukturální a chemické analýzy poukázaly, že teplotní generace detektorů způsobuje difuzi kovu použitého při kontaktování a stopových prvků hlouběji do objemu krystalu. Část mé práce je věnována modifikaci povrchu svazkem argonových iontů a jejímu vlivu na chemické složení a morfologii povrchu.
