Enterprise Network IPS Security
Jakab, Vojtěch ; Babnič, Patrik (referee) ; Červenka, Vladimír (advisor)
This bachelor's thesis addresses the local area network security. The scope of this thesis is to explore the possibilities of security of these networks and introduction of some attacks which can threaten these networks. The main goal, however, is to design maximum security measures of testing network. CISCO router and Fortinet's firewall are available. Their configuration is limited by possibilities of their operating systems. By the appropriate programms the configuration of IPS configured on firewall is examined and they are used to try to evade this component. The last part of this work deals with executing particular network attacks. They are alaysed and agains successful attacks are proposed apropriate countermeasures.

Cross-sectional study of selected legal regulations in the field of alcohol with a specific focus on the methanol case
Fialová Mikešová, Tereza ; Šejvl, Jaroslav (advisor) ; Rolová, Gabriela (referee)
Background: In 2012, there were massive poisonings with harmful alcohol laced with methanol throughout the Czech Republic. As a result of intoxications, not only death but also damage of health of various degrees occurred. The event, which directly endangered public health, brought new experience and, among other things, confirmed the thesis accepted in professional circles that no way of consuming alcohol is necessarily safe or even beneficial to health, which is why there is a need to change the approach to alcohol. Aim: The aim of the bachelor thesis was to briefly describe the development of selected legislative regulations aimed at reducing alcohol consumption on our territory from the establishment of the independent republic to the present day and to describe the procedure and measures applied by state administration authorities during methanol poisonings and the effects of this phenomenon on the further development of legislation in the context of the event. Methods: Content qualitative analysis of written materials was used. In the first place, suitable documents issued by state administration bodies, legal regulations published in the Collection of Laws and media communications were selected. The obtained data were subsequently subjected to a qualitative content analysis, on the basis of...

The toxicity of vitamin D
Drouliskou, Eleftheria ; Mladěnka, Přemysl (advisor) ; Janoušek, Jiří (referee)
Vitamin D has essential role in skeletal health, however studies over the recent years have outlined its implication in many other physiological functions. The importance of vitamin D for health has, on one hand, raised needs for supplementation but may, on the other hand, lead to excessive administration. Vitamin D toxicity or hypervitaminosis D due to excess of vitamin D is a medical condition manifested mainly as hypercalcemia, with mostly gastrointestinal and neuropsychiatric symptoms. Long-term administration of large doses of vitamin D can result in vascular calcification and hence by associated with a cardiovascular risk. Hypervitaminosis D is extremely rare likely due to high therapeutic index of vitamin D. The clinical research shows an administration of 10.000 IU/day of vitamin D, which meets the criteria for the tolerable upper intake level, even for extended period, is probably not associated with adverse effects in almost all individuals in general population. However there are case studies globally showing vitamin D toxicity can occur due to misuse of over-the-counter vitamin D supplements, inappropriate prescribing or uncontrolled administration of high dose unlicensed preparations.

Cognitive sequelae from methanol poisoning
Bernášková, Lucie ; Kulišťák, Petr (advisor) ; Šivicová, Gabriela (referee)
This thesis focuses on cognitive functions in patients after methanol poisoning. The theoretical part consists of a description of methanol, characteristics of methanol poisoning and its neurological sequelae. Methanol poisoning affects the basal ganglia, therefore we describe them and their role in cognitive processes. The theoretical part also describes a case of mass methanol poisoning in the Czech Republic in 2012-2013. The practical part compares results of a control group and a group of patients poisoned with methanol in cognitive assessment. Results show that the patients after methanol poisoning have significantly lower scores in tasks testing memory and executive functions than the control group.

Role of therapeutic approach in the treatment outcome, hospital costs, one-year post-hospital medical costs and quality of life in the patients who survived acute methanol poisoning.
Rulíšek, Jan ; Zacharov, Sergej (advisor) ; Máca, Jan (referee) ; Kieslichová, Eva (referee)
(English) Background: Methanol poisoning is severe medical condition with a need of urgent intensive treatment. Mass poisoning outbreak took place in the Czech Republic in 2012-2013. Costs of hospital treatment of methanol poisoning present significant financial burden to healthcare systems. The effect of treatment modality choice on clinical outcome and healthcare costs is not known, as well as its impact on the quality of life of methanol poisoning survivors after hospital discharge. Aim: To compare different therapeutic methods, choice of antidote (fomepizole versus ethanol) and extracorporeal elimination method (intermittent vs. continuous dialysis) for optimizing clinical outcome, cost-effectiveness, hospital costs, post-discharge costs, and the quality of life in survivors. Methods: For prospective cohort study, all patients hospitalized with acute methanol poisoning were included (n=106); for hospital and one-year healthcare costs study, all survivors of acute methanol poisoning (n=83) were included. For longitudinal quality of life study all survivors with informed consent (n=54) and control group of chronic alcohol abusers, age- and gender-balanced, without history of methanol poisoning (n=23), were included. Results: Comparative data of clinical effectiveness of elimination techniques...

A new approach for assessing the suspected pesticide poisonings of honeybees: certified methodology
Erban, Tomáš ; Kamler, Martin ; Kadlíková, Klára ; Markovič, Martin ; Titěra, Dalibor ; Seifrtová, Marcela ; Halešová, Taťána
Honeybee colonies are exposed to hundreds of plant protection products, which are especially due to improper use possible source of honeybee poisoning. The methodology introduces to the issue of honeybee poisoning including legislation and contributes with novel aspects to the indication and evaluation of the suspected honeybee poisonings, which are anually investigated by the State Veterinary Administration and the Central Institute for Supervising and Testing in Agriculture in Czechia. The methodology provides instructions to identify honeybee posining and notification of that finding. Moreover, possible confusions of the poisonings with honeybee diseases are highlighted. Some sections of the methodology provide innovative recommendations for improvement of honeybee poisoning assessing including determination of the extent of colony contamination. The present methodology is useful for the state administration, beekeepers, scientific and educational purposes.

Mapping and analysis of illegal poisoning of wildlife in the Czech Republic
SLAVÍKOVÁ, Kristýna
Pesticides, rat control or targeted placed, poisoning bait by carbofuran. These and many other ways can cause the poisoning of a wild animal. Whether targeted poiso-ning of a particular animal poison or unintentional poisoning of a non-target individu-al occurs, this behavior has always fatal consequences. The persecution of nuisance animals, such as Foxes, Martens or other predators, has an influence on the whole of the population. Often poisoning bird of prey is a White-tailed Eagle, in which case every poisoned individual has an impact on the whole of the population. Unfortu-nately, this made bait is poisoning far more animals, especially for scavengers and carnivores. This paper explores the available data of poisoning animals and maps their occurrence. The data was obtained from the database the Animal Rescue Centre and the Free Wings in the period 2009-2016. Among the most commonly accepted ani-mals in the stations was the Roe Deer with poisoning caused by the Rape. Water-borne birds were Often bothered by botulism, followed by individual poisoning with poison on the rodent and poison on the Slugs. Carbofuran was most poisoned by the White-tailed Eagle, the Common Buzzard, and the Common Raven. Among the poi-sonous species are also the endangered the Red Kite, the Black Kite, and the Golden Eagle. Furthermore, it has been found that individual years have no effect on poison-ing. The difference in the number of birds and mammals poisoning was not detected. The influence of the month on the data obtained from stations was not found, the number of carbofuran poisoning is higher in March, and especially in April. In the analysis of spatial differences, there is also a balance between most regions. The Cen-tral Bohemian and the South Bohemian regions are markedly different. Above-average numbers of carbofuran poisoning originate in the regions of the South Bohe-mia, the Vysočina, the South Moravian and the Ústecký region.
