Prevention of chronic hepatitis
Kovaříková, Kristýna ; Horák, Jiří (advisor)
The topic of his thesis Prevention of chronic hepatitis I chose both because of the interest in this issue and for providing opportunities for Precautionary question this current issue affecting not only professional, but especially the general public. The aim of this work was to give a brief overview of the various etiologic agents involved in the development of chronic hepatitis. The text is devoted to attention essentially only chronic viral hepatitis, which may preventive measures apply most. Other chronic hepatitis are only listed in the Summary and below them are not given wider attention. Preventive part is focused on general preventive measures against the spread of hepatitis vaccination against hepatitis B. The basis for the treatment of this topic was largely applicable legislation governing the issues.

Risk elements contamination in Kutná Hora region and possibilities of its usage in paleoenvironmental research
Horák, Jan ; Hejcman, Michal (advisor) ; Jaromír, Jaromír (referee)
The dissertation focuses on topic of using risk elements contamination as a stratigraphic marker in palaeoenvironmental research. The contamination is not studied only as itself, but is viewed as a way to analyse and interpret the sedimentary record of historical events. The contamination carries the information about its original place, its original activity, about development of the landscape.
The Kutná Hora region (central Bohemia; 49°57'0.170"N, 15°15'59.877"E) is a region of important historic mining and smelting activity. The mining started in 13th century and lasted until half of 16th century. Then only sporadic attempts of renewal were made. Spatially limited mining was renewed in second half of the 20th century. Therefore, it is highly probable to find here the contaminants in the role of stratigraphic markers. In the research were used mainly As, Be, Cd, Co, Cr, Cu, Hg, Pb, V and Zn as these are the most analysed in contamination studies performed in the region.
The aims of the dissertation were to answer these questions:
To characterize the contamination
- Are some risk elements typical for the contamination originating from the mining and smelting?
- If so, is their environmental (spatial, sedimentary) manifestation diversified?
- Is possible diversity spatially related to particular landscape features or areas?
- Is possible diversity connected to particular activities?
To use the answers in analysis of particular sites
- Is it possible to use the risk elements contamination as stratigraphic marker in fluvial sediments?
- How is the interpretation of particular site influenced by the whole context of regional contamination?
The core of the research is the metaanalysis of contamination data coming from region (the data obtained by our research and also from other studies). The results have brought not only basic characteristics of contamination, mainly concentrations. The crucial result was the structure of studied elemental complex. Only As, Cd, Cu, Pb and Zn are connected to contamination originating in mining and smelting. Other elements - their concentrations and spatial distributions - are uninfluenced by mining and smelting activities. More, the information about connection of As and Cd to mining and Cu, Pb and Zn to smelting was revealed. Both groups recorded with different spatial distributions. Also comparison of results by different approaches has shown that some statistical processing (clr-transformation) of such dataset was much better for interpretation than analyses of only concentrations values.
We studied also the area of confluence of two rivers - Klejnárka (main river draining contaminated region), which is tributary to Labe (Elbe) river. The contamination is still recognizable here, but the diversity between contamination elements is not. The confluence of rivers strongly dilutes the contaminated material. The concentrations decrease. Also here clr-transformation of data enabled to analyse structures of contaminants spatial distribution unrecognizable by concentrations values.
We performed also two vertical profiles analyses. It was shown, that it is highly risky to interpret data of such origin without the complex information about regional contamination context. It was revealed by contextual interpretation of data from one of the profiles, that there is a mixing of geochemical data coming from different statistical populations. The contamination works there as only one of the factors influencing sedimentary record. The site is therefore suitable for statistical testing of two populations mixing, outliers` detection and the like.

Issue of Deer ked from the Perspective of Monitoring
Bjelková, Karolína ; Horák, Jakub (advisor) ; Holuša, Jaroslav (referee)
This bachelor thesis concerned issue of deer ked from the perspective of monitoring to wild game on the skin pulled from hunted animals and human specimens showing two locations for themselves binding - Mala Morava and Libava. Deer ked is hematophagous ectoparasite of cervids, which in recent years expanded its area of occurrence from Europe to America. The aim of this study was to determine the prevalence and intensity of infection and to evaluate the influence of the nature habitant, weather factors or determination of sex by the host.For identification were examined 95 animals in body area, on the nape and genitals. The overall intensity of the attack were analysed in relation to age, gender, weather and landscape characteristics of point of capture. Results of occurrence of deer ked are described and evaluated demostrate the prevalence of infection almost 100%, but the rate pressure of animals ranged from 0 to 10 deer ked 100 cm-2. The highest occurence was found in males, and simultaneously was also associated wit a host of areas on the body where the most parasites were found on the genitals, 7-10 pieces. The significant influence had the temperature. The influence of rainfall was insignificant. It was found that the highest occurrence is on the animals, which use habitant fields and meadows, probably due to positive effects of solar radiation and thereby raise the surface temperature of the skin. Localization of body aeas can be used to setting means for effectiveness insecticide against these parasites.

Bark beetles in forest ecosystems with disparate disturbance regimes
Zemanová, Jana ; Horák, Jakub (advisor) ; Jiří, Jiří (referee)
This thesis evaluated the influence of the forest environment with various rate of disturbance. Studied sites were left to spontaneous succession. The method of trunk window traps was used. These traps were divided into pairs at monitored sites. Each pair comprised active (with yellow label attached) and passive trap. The influence on the bark beetles was evaluated by statistical analysis. In total, 346 individuals were captured and 12 species of bark beetles were identified. The influences of the environment (circumference of tree trunk, canopy openness, dead wood, altitude and type of trap) were significant for the number of individuals, the total body length, the width of shield and the length of elytron. Wing length was only affected by circumference of tree trunk, canopy openness and dead wood. Number of species was only influenced by altitude.
