The study is designed as a prospective clinical trial. Patients with histologically proven head and neck cancer treated by curative radiotherapy were included. The aim of this study was to investigate the relationship between pretreatment or posttreatment nutritional status and overall surival or locoregional / distant control. Pretreatment and posttreatment nutritional status was evaluated by body weight, body mass index, total serum protein, albumin, prealbumin, transferin and cholinesterase. Univariete and multivariete regression analyses were applied for prognostic factors associated with survival or tumor control. In this study we demonstrated, that poorer nutritional status prior curative radiotherapy, has a negative impact on subsequent control of cancer. The most sensitive parameter was serum cholinesterase. Serum cholinesterase  108 kat/l was the independent negative prognostic factor for both locoregional and distant tumor control. Results of this study indicate the need for intensive nutritional support before starting of curative treatment.

The diploma thesis is focused on the legal nature assessments of medical assessment service. The medical assesment service has seen many changes over the course of history, and its competence is constantly changing and evolving. Unfortunately, the nature of the assesment service is sometimes ambiguous for the non-professional public and is thus viewed very skeptically. Nowadays, only a few experts are dedicated to this topic, so I decided to unify the information and summarize the main objectives of the medical assessment service. In order to better understand and illustrate the rights and duties of this service, I also looked into history. Given the nature of the work, I decided to work on theoretical work, which points out not only the historical development in the Czech Republic, but also in Slovak Republic, further it focuses on the current state and definition of terms necessary for understanding the work of the medical assessment service. The objective of the work is to map the system of medical assessment service and work is thus a summary of information not only for the non-professional public, but also for study purposes and awareness of social workers who meet daily with many questions on this topic. The medical assessment service affects many human life stages, so it is not only about assessing health status for pension insurance, but also for health insurance or ensure the social services. Since many authors are not concerned with the topic, it is sometimes quite difficult to find a clear definition of the legal nature of individual assessments. However, the legal nature of the assessments is enshrined in the law, and also affects other life stages of the person that being assessed and claims not only for financial but also for social security, and it is therefore important to deal with this topic and its changes and submit new and comprehensive information.

In this diploma thesis is elaborated the overview of organic farming in the Vysočina region, focusing primarily on the current state of the organic crop production and analysis of areas that are in operation organic crop production inputs in terms of the most problematic. The first part presents information about number of subjects, area of agricultural land and most often cultivated crops in organic farming in the region of Vysočina from registers of environmental entrepreneurs on the site of the Ministry of Agriculture. These data are then compared with data from other regions in the country. The second part is focused on the evaluation of areas that are in terms of the operation of the organic plant production the most problematic. Data for this part of the thesis were determined by questionnaire.

The aim of my work was to evaluate 14 small-scale specially protected areas, located in Landscape area Lužické hory. This evaluation was accomplished by the aid of Methodology of Evaluation of State and Management of Small-scale Protected Areas (Svátek, Buček, 2005). The total area assessed is the 286.75 ha. State of 2 areas was rated as excellent (grade 1), 9 areas were rated as good (grade 2) and 3 areas were rated as average (grade 3). Management of 4evaluated areas was rated as excellent (grade 1), management of 9 areas was rated as good (grade 2) and the last one area was rated as average (grade 3). The best criterions of the protected area state were the condition and the structure, whereas the worst assessed criterion was the other negative influences. The best criterion in evaluating the management was the documentation, on the other hand, the reduction of other negative influences criterion was evaluated as the worst one. The state of PP Pustý zámek was evaluated as the best, the state of PR Vápenka was evaluated as the worst. The management of PP Louka u Brodských was evaluated as the best, the management of PP Vápenka was evaluated as the worst.

This diploma thesis deals by historical development vegetation castle park in Sobotín, evaluation, proposing care technology and setting managment of care for park. In the summary issue is introducing legislation related to this work. In this chapter is outlined methodology which are used for inventory of trees and defined purpose an using care technology. In the chapter Surveys and analyzes is systematic described formation castle park and especially description histrorical development composition park until now. In the results are evaluated staying trees in the park and there are interpreted results on the based of inventory and clasification trees. Subsequently was evaluated and described potential dendrology this park. According to results were designed care technology for trees and was determined care management after ten years.

In this thesis has been mapped the current condition and expansion of the vegetation with a focus on bilberry (Vaccinium myrtillus) between 2000 and 2012 in large-scale protected area Praděd by using the methods of remote sensing. For the mapping of the total surface area of 144 hectares was used supervised and unsupervised classification of image data. From the results arised that a species of Vaccinium myrtillus has spread out to vegetation above tree line.

This diploma thesis elaborates on the influence of constructed wetlands on macrozoobenthos of the respective recipients. Constructed wetlands near the town of Hostětín were chosen for this research project, as well as its recipient Kolelač river delta where cleaned water is drained into. The report also contains analysis of Kolelač's stream area which took place during April 2013 under the auspices of the TA02020128 project by T.G.Masaryk Water Research Institute Brno. Investigation was performed in five sites labeled L1-L5. Of these, L3 was placed in the vicinity below the outfall of constructed wetlands. The research involved a one-time collection of quantitative and qualitative samples of macrozoobenthos by the so called PERLA method. Different characteristics for each facility were analyzed in order to carry out a comprehensive survey. This included for example: abundance, amount of taxons; diversity; taxonomic composition of microzoobenthos; as well as other ecological factors of Kolelač stream quality affected by the constructed wetlands. Macrozoobenthos' studied using abiotic factors demonstrate that the L3 drainage area in closest proximity to constructed wetlands is more polluted than other locations. Analysis by a multi-metric index ranked L3 into the 3rd group, indicating that a medium ecological water quality was present, whereas other locations are ranked into the 5th group with the highest ecological quality of water.

Since the year 2013 there is going a hydrobiology monitoring of some selected ponds in Duchcov. It is Rybochovný n. 1, Rybochovný n. 2, Rybochovný n. 3, Kravský, Růžový, Dubský and Barbora onces, when all ponds were for some time monitored in basic hydrochemical parameters: temperature, alkalinity, conductivity, oxidation reduction potential, dissolved oxygen concentration in water, transparency and turbidity. I examined seasonal change in phytoplankton and zooplankton composition. I compared my results with data from previous years. In these ponds is a risk of eutrophication, resulting in the occurrence of algal blooms. Several situations with the occurrence of algal bloom was observed during monitoring. This would may be problem for ecological conditions of pond´s reservoirs, also for fish composition because of oxygen out-pumping. There weren´t noticed extreme changes during pH monitoring, even so it is important to monitor the supply of nutrients and in case of deflection to make various steps.

The main aim of this work was to learn about the health condition (foliage and yellowing) the structure and the growth of the spruce forest stands on two research areas at Stožec in the Šumava Mts., one of which area is fertilized by the product SILVAMIX MG and the second area is checking. Yellowing and defoliation of spruce forests in Šumava due to a lack of magnesium were repeatedly noticed in the eighties of the twentieth century. There was an experiment focused on the research reaction of spruce forest application of magnesium fertilizer (SILVAMIX MG NPK) in 1998. Fertilizer was applied manually in the spring of 2000 in the spruce-beech and spruce forest vegetative stage at a dose of 96,5 kg Mg/ha. On the fertilized areas was a significant improvement in the health condition of forest and also a reduction of yellowing. In 2005, yellowing symptoms of Norway spruce (Picea abys) almost disappeared. There is an every year yellowing and defoliation stands on the unfertilized control areas except the year 2006. There was a slight improvement in the health condition of stands in this year. We can say that the application of appropriate fertilizer leads to a significant improvement in the health condition of stands and it helps to their overall stability.

This diploma project is specialized on memorable trees in the Sokolov Region which is a part of the Karlovy Vary Region. The work is divided into a theoretic part and a research part. In the theoretic part, there is a historical development of memorable tree care in the Czech Republic from past to the present, a legislative base, possible ways of arboricultural care and informations which are gained from Nature Conservation Agency of the Czech Republic website described. This agency register memorable trees in the Czech Republic. The research part is focused on the field research of selected memorable trees in the Sokolov Region and the evaluation of its state of health, location description, quality of provided care and the way of memorable trees are marked. During the field research, there was a location of selected objects marked in tourist maps and captured by GPS navigations because of a easier orientation. In the end, there are field research results summarized and evaluated. The works purpose is to get a bigger knowledge about memorable tree care and to find more easily selected trees because of its mapping.
