The Leisure Time Activities at the First Stage of Basic School
TOMANOVÁ, Ivana
Leisure is part of our everyday lives. His name makes us feel comfortable. We introduce a space that is designed only to us, we can devote to activities that interest us, while the rest. The current development allows the development of leisure activities, which can be paid. Emerging leisure facilities, which are mediated by different menu of activities from which each selects just the area that satisfies him, calming and fulfilling. The aim of this work is to map the problem of free time, 1st degree students of primary schools and offer a variety of leisure activities, which pupils can take. In the theoretical part of the converged, leisure and recreational activities for their problems and opinions of various authors on them. Closer look at the distribution activity, according to the content of activities and institutions providing leisure activities. The practical part of the surveyed range of leisure activities in selected institutions through questionnaires received by the directors of these institutions. The survey will also focus on parents' views and satisfaction with these offerings, which also received questionnaires.

Has UV radiation an impact on tadpoles' movement activity?
KLAPKA, Vladimír
The increasing level of the UV-B irradiation due to depleting of the ozone layer is considered to be one of the causes of global amphibian declines. The UV-B radiation causes damage to the DNA in the nuclei of the skin cells and their eventual death. In many amphibian species there was found a negative influence of the UV-B radiation on the hatching success of tadpoles and their subsequent viability. It has been assumed that tadpoles are able to actively avoid places with the higher exposure of the UV-B radiation thanks to their locomotion. In this experiment tadpoles could have chosen between a zone with the UV radiation (UV-B and UV-A) and without the UV radiation. The tadpoles have not been exposed to the UV radiation before the measurement started. The location of the tadpoles during the measurement was recorded by CCD camera. A computer program EthoVision then evaluated the time that these tadpoles spent in each of the zones and the total path length these tadpoles has swum in the zones. The measurements were performed for two groups of tadpoles differing in age to determine whether the level of development may affect the tadpoles' preference to the UV radiation. The tadpoles in both groups spent more time in the zone without the UV radiation. The tadpoles in the more advanced development phase have spent 7 times more time in average in the zone without the UV radiation than in the zone with it. The tadpoles from the second group have spent in average 2.5 times more time in the zone without the UV radiation than in the zone with the UV radiation. The total swimming path length of advanced tadpoles was almost 2.5 times longer in the zone without the UV radiation than in the zone with the UV radiation. Conversely, the total path length of younger tadpoles did not significantly differ between the zones. The total time spent in the zones with / without the UV radiation did not differ between the groups of tadpoles. Also the total path length did not differ between the groups in the zone with the UV-B radiation. However, the total path length of tadpoles had differed between groups in the zone without the UV radiation.

Time-resolved fluorescence in investigation of colloid system
Černá, Ladislava ; Ouzzane, Imad (referee) ; Mravec, Filip (advisor)
This thesis is focused on determination of the basic spectral characteristics, such as fluorescence maximum and lifetime, of fluorescent probes prodan [6-propionyl-2-(dimethylamino)naphthalene] and perylene by steady-state and time-resolved fluorescence spectroscopy. Time-resolved measurements were realized through TCSPC method (time-correlated single photon counting). The characteristics of prodan were found in water, acetone, n-heptane and in mixtures of these, so that a polar scale of environments would arise. Both of the mentioned probes were further investigated in systems of aqueous solutions of hyaluronic acid (300 kDa) at the concentration of 10 mg•l-1 together with cationic surfactant CTAB (cetyltrimethylammonium bromide) at the concentration range from 0.01 to 0.20 mmol•l-1 (before CMC). The aim was to confirm the reach and the range of critical aggregation concentration of the surfactant (CAC), to uncover the basic spectral characteristics of the mentioned probes in this concentration range and to verify the stability of this system in the presence of NaCl at the concentration of 0.15 mol•l-1. Furthermore, by TCSPC method were obtained time-resolved emission spectra of prodan from the system of hyaluronic acid and CTAB at one concentration of CTAB in CAC interval both without salt and with salt at the concentration of 0.15 mol•l-1. The obtained time-resolved emission spectra correlated with the results of the CAC concentration range measurement. After addition of salt the system of CAC proved to be unstable.

Nursing care as provided to ante finem patients
JANSOVÁ, Markéta
The subject of death and dying is still considered a taboo in our society. It is awkward and anachronistic since our times require people full of life and vigor. The terminally ill are often snubbed by the society. Though being well aware of the unfavorable prognosis, many a doctor tries to treat the patients to the very last moment, and he or she perceives the death as a personal defeat. In 1967 Cicely Saunders, an English doctor familiar with the dismal conditions of dying in the then society, founded in London the St. Christopher's Hospice, the first modern facility of this kind. The philosophy of this effort has been perpetuated in the Hospice of the Agnes of Bohemia established in 1995 as the first hospice in the Czech Republic. The Bachelor Paper aimed to assess the possibilities of providing the ante finem care by health-care personnel at a hospital and a hospice. The Paper investigated these hypotheses: H1 - Health-care workers provide the ante finem patients with health care in conformity to the standards applicable to both types of the facilities; H2 - Approach of the personnel to the care is dependent on their emotional stability; H3 - Health-care personnel in hospitals are not aware that the art of accompanying is a part of the nursing process. The surveyed sample was compiled of nurses on the staff of the Internal Medicine Ward and the Post-Treatment Ward of hospitals in České Budějovice, Jihlava and Třebíč and the hospices in Prachatice, Červený Kostelec and Brno. The data were gathered through a questionnaire. Altogether 170 questionnaires were distributed and 136 out of them were processed in the final assessment. As follows from the assessment results, the care provided to the terminally ill patients in hospitals is affected primarily by time pressures and by the fact that the nursing staff are not fully aware of the possibilities that palliative care offers, while in hospices the conditions available for the palliative care have a quality basis. Results of the Paper will be given to one of the hospitals and two hospices specified above, where they can inspire some new ideas about possible improvement in providing the palliative care.

Epidemiology of tuberculosis - reaction on vaccine BCG
FOŠUM, Pavel
Epidemiology of tuberculosis-reaction to BCG vaccine World Health Organization records nine million people worldwide who fall ill with tuberculosis and more than three million who die of this disease a year. Tuberculosis has been known for a long time and despite the discovery of Mycobacterium tuberculosis etiological role by Robert Koch, the invention of RTG diagnostics by Roentgen and effective treatment using antibiotics by Waksman as the first, this disease still represents a considerable risk for society. Prevention using BCG vaccine has positive as well as negative aspects. This thesis is focused on describing newborn vaccination coverage, occurrence and duration of side and adverse effects after the application of BCG vaccine during the first days of life and on the influence on the following compulsory vaccination. We used the method of quantitative research in the form of epidemiology descriptive study using the technique of individual data collection and analysis. As a research area the group of children born in 2004, 2005, and 2006 was used. The group of 804 children (410 boys and 393 girls) was selected by the technique of random cluster sampling. We found out that out of 804 respondents 98.6 % were vaccinated with BCG vaccine. The group of 11 children was not vaccinated due to: HBsAg positivity of mother, low birth weight or health problems. Reaction after BCG vaccination was not healed until the next planed shot in 307 children (38.1 %). There were 4 people with no reaction at all to BCG (0.8%). The most frequent side (adverse) reaction after vaccination was scar unhealed at the time of next planed vaccination in 274 cases, (34.1%). Monoreactions accounted for more than a half of recorded reactions. Reaction time period was in the range from 11 to 300 days. Median of reaction time period was 30 days. We did not find any serious adverse reaction. Our research demonstrated, that frequency of side and adverse reactions after BCG vaccination is high (38.1 %). These are mainly benign side effects. We found that these reactions lead to postponing of the subsequent vaccination of the compulsory vaccination scheme in all who reacted to BCG vaccination. The occurrence of side reactions after BCG vaccine raises the question of appropriateness to carry out the BCG vaccination in first days of life. The results of this thesis can be used as a pilot study for the whole country study of mapping side and adverse reactions and further consideration of compulsory vaccination scheme.

Calculation of electrodynamic forces in 1600 A circuit breaker
Musil, Pavel ; Bušov, Bohuslav (referee) ; Valenta, Jiří (advisor)
The thesis is focused on the calculation of electrodynamic forces that counterwork on moving contacts of compact circuit breaker BL1600 from the company OEZ Letohrad. The thesis is divided into separates chapters that build on themselves. In the introduction the reason why we deal with calculation of dynamic forces and structural arrangement of current carrying path is described. In the following chapter there is a theoretical analysis of electrodynamic forces that conterwork on individual parts of circuit breaker´s element. The third part is devoted to structural arrangement of the circuit breaker BL1600. In this part we can find an example of using the circuit broker Modeion in practice. Two next chaptures deal with adjustment of the model of current carrying path which then serves for the calculation of electrodynamic forces. The rest of the thesis is devoted to my own calculations. These calculations are mainly stationary where we try to find the forces that conterwork on the contacts in a steady current and in a point in time. There are also dynamics calculation when we can watch the forces that counterwork on contacts in a certain time interval. The last chapter is devoted to a stationary calculation of forces that counterwork on the electrical arc which arises while turning the short-circuit current off. The obtained results are evaluated in partial conclusions of this thesis.

Alcohol as a common phenomenon now
HANZALOVÁ, Zuzana
There are many reasons why people tend to consume alcohol. One of them is the influence of society. People practically get acquainted with alcohol in early childhood during different family celebrations where drinking alcohol is very tolerated. Certain amount can be accepted. Another reason, why people tend to drink alcohol, could be very individual. People are not able to deal with their problems and stresses, which are brought with their workload and this rushed age. But in both cases it could lead to the situation where the first shots do not work any more. Their amount must be increased ? but that also means higher load for body. Higher consumation of alcohol also brings the risk of exceeding of certain border. Person starts to drink excessively, no regard to his (her) health, age or suitable timing. The theoretical part of my thesis is aimed to the reasons of alcoholism formation and single stages of addiction. It also describes secondary illnesses to alcoholism, prevention and treatment of that. It deals with the groups of people which are the most endangered by addiction. The work contains the comparation of domestic and world statistics. The basis of the practical part is the research of different age groups of inhabitants which is aimed to alcohol attitude, degree of tolerance, finding of drinking frequency and amount of drink alcohol, differences between men and women. In cooperation with mental institution in Jihlava I have watched and treated the life destinies of concrete persons. There are also statistics of mental institution and statistics of accidents caused by driving under alcohol influence processed.

Differences and similarities on the approaches of buyers from X and Y generations regarding sustainable procurement
Lacour, Maxime ; Štěrbová, Ludmila (advisor) ; Geniaux, Isabelle (referee)
Responsible procurement has become a real challenge for companies following the current trends of Corporate Social Responsibility (CSR) and more and more ethic-oriented customers. Differing from the concept of green procurement this concept of responsible procurement supports the willingness of companies to have ethic and sustainable supplies. The usual criteria in procurement such as price performances innovation terms and time of payment have increasingly been coupled with more ethic-oriented ones. These criteria related to ethics combine both social and environmental responsibilities of suppliers and stakeholders such as energetic savings and the possession of a particular certification. Currently many call for tenders set ecological requirements for suppliers or subcontractors even in non-strategic procurement activities. The goal of this thesis is about comparing this approach to responsible procurement between buyers from the X and Y generation: do they share the same ideas and priorities concerning responsible procurement? For both of these generations are the advantages and drawbacks of responsible procurement similar?

The effectiveness of welding on furnace structures.
Rousová, Michaela ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
This diploma thesis is resolving all the possibilities of enhancing the efficiency of furnace structures welding. Small batch production does not offer many possibilities for implementing mechanization or automation. On the other hand, when using a big batch production, efficiency can be enhanced by means of a robotic workstation. When the production batch is big enough, we will see a costs save after a short time, mainly in labor costs. This means the return of investments will be in short time period. In the LAC company there are three types of products made. At laboratory furnaces the efficiency can be enhance by using fixtures. At other standard and atypical furnaces is very difficult to design fixtures or positioners because of their different sizes. Big complication can be also a company location on second floor. The most suitable product regarding to welding efficiency enhancement is big batch production of heaters. For this type the welding time can be shortened by means of a robotic workstation.
