The Comparison of Data of Current Radiation Situation with in Europe
STRÁNSKÝ, Petr
The aforesaid topic of this bachelor thesis was chosen mostly for the current issue of the radiation security, which importance will most likely rise in the future. That is why it should be taken more seriously. The purpose of this thesis was to compare the availability of data on the current radiation situation in different countries of Europe and at the same time to consider the clarity and the way of presenting the given facts online. Afterwards it was possible to answer the research question: "Are the data given by different countries comparable?" In the theoretical part of this thesis the author used the method of research by studying different literary sources. The crucial terms of the topic were defined, the sources of the ionizing radiation were described and this part also described the movement of the radioactive matter in the environment and its impact on human organism. Furthermore the author focused on the system of the monitoring of the radiation situation, mostly in the Czech Republic. Last but not least the thesis deals with the legislation of the radiation monitoring and also the exchange of data, mainly the European radiological data exchange platform (EURDEP). The outcomes of the thesis were gained by a comparative analysis of the websites which are focused on the radiation situation in different states. The results show, that most of the European countries are focused on continuous monitoring of the batch input. Other published data came mainly from the measurements of the radionuclide volume in the air, in particular from the measuring of the activity of aerosol and atmospheric fallouts. Other monitored items compared in this thesis were not so available. The clarity and the way of presenting these data online were quite various by different countries. The best compiled website was the Czech application MonRaS, which was the only of the compared sites which offered data of all the considered items of the radiation monitoring. The thesis will be used for further studies of the topic and can broaden the knowledge of the availability of radiation data online.

Impact of Warm Ischemia on Renal Function - Clinical Model of Tumor Resection of Solitary Kidney
Stránský, Petr ; Hora, Milan (advisor) ; Broďák, Miloš (referee) ; Doležel, Jan (referee)
Objective: The aim of this work is to evaluate the effect of warm ischemia on renal function. Methods: Within a multicentric study, the data about tumor-affected solitary kidney were obtained from 9 urological centers in the Czech Republic. Patients were divided into groups according to the WIT (warm ischemia time). In each group the mean preoperative serum creatinine was determined, as well as on 3rd and 7th postoperative day and the lowest GF postoperatively. In each group the mean R.E.N.A.L. nephrometric score was determined. Results: The study compriese data totally of 97 patients. The open approach was chosen in 78 cases, in 16 cases laparoscopic approach was chosen. The robotic surgery was performed in 3 patients. PN with zero ischemia was performed in 29 patients (30%). Conclusion: Our findings confirm that non-clamping partial nephrectomy in a solitary kidney minimizes renal injury. For the non-clamping partial nephrectomy can be mainly indicated smaller exophyticall tumors without deep parenchymal invasion. Unfortunately, most of PN should be performed with vascular clamping, allowing precise closure of collecting system, vascular and parenchymal defect, especially for larger tumors with deep parenchymal invasion. According to our observation that WIT of 15 minutes for a kidney is safe. Clamping of...

Freeriding - competition forms of skiing
Stránský, Petr ; Matošková, Petra (advisor) ; Klein, Petr (referee)
Name of writing: Freeriding - competition forms of skiing. Objective of work: Compact and complex survey of ski-racing in the free rough - freeriding. By the help of public inquiry approach idea of this sport from the point of view of competitors. Used methods: It's exploration type of writing based on documents analysis and public inquiry work up. Results: Comprihensive review of freeriding was written on the basis of literature available. We concentrated on beginnings of freeriding and history of freeriding, subsequently on contests and rules of this sport. Based on the inquiry we found out the competitors attitude to this kind of skiing. Key words: Skiing, free riding, freeskiing, contests, rules of competition.
