Comparison of knowledge from nuclear physics for protection of inhabitants at laical and expert community
BARTOŇOVÁ, Miroslava
The primary objective of this thesis was to achieve comparison of knowledge of nuclear physics for population protection between general and professional public. This idea is based on the assumption of the possible existence of extraordinary events with occurring ionizing radiation and for this reason it is necessary to train specialists for the eventuality of these cases. These professionals should have wider knowledge of nuclear physics than general lay population. This issue has not been examined with lay and professional public yet, as well as there has been no comparison of the two listed groups. Another objective of this thesis was to structure the basics of nuclear physics for workers in civil protection training. For this purpose, the author of this work created a model of nuclear physics, reflecting the basic knowledge of nuclear physics, based on the analysis of the curricula for the IRS. The author explored the forms of studies of university program for the public protection, of members of the Fire and Rescue Service, of university study program for paramedics, of staff of the Anti-organised crime department of Police of the Czech Republic and of the Customs Administration. The analysis showed the widest expected range of knowledge at the technicians of the Chemical Service of the Fire Rescue Service of the Czech republic (the chemist), who are professionally trained in the handling of hazardous substances and ionizing radiation sources. These members have become the monitored representatives for the professional community in the survey of this thesis. Lay general public was represented by people from the social circle of the author of this work, i.e. they were an unrepresentative sample of the general public. The theory of physics curricular process was also used, the application of which served to create an alternative test from nuclear physics, which was presented to the respondents. The questionnaires were filled in by 52 technicians of the Chemical Service of the Fire Rescue Service of the Czech republic from different parts of the country and by 50 people of the lay public. It should be noted that the questionnaire was created considering the training of the technicians of the Chemical Service, in which nuclear physics has only a supporting role. One of the objectives of the thesis also included the subsequent statistical evaluation of the applied tests of the knowledge of nuclear physics. For validating mainly the non-parametric and parametric hypotheses tests were used. For the theoretical division of knowledge among professionals the existence of the Poisson distribution (the distribution of "rare" cases) was assumed and the theoretical division of investigating the general public should be close to a normal distribution. Also the difference between the knowledge of laymen and experts was investigated. To meet the defined objectives of this work three hypotheses were set, for their verification the methods of descriptive and mathematical statistics were used. Hypotheses were set as follows: H1. Theoretical distribution of knowledge among the general public will be close to normal distribution. H2. Theoretical distribution of knowledge among professionals will not have a normal distribution. H3. Comparison of knowledge in both groups by using the parametric tests will lead to the adoption of alternative hypothesis. All three defined hypotheses were verified via statistical survey and accepted positively. The test, however, does not show the ability or inability of the tested experts to carry out practical tasks associated with their profession. This thesis only aimed to discover theoretical knowledge of nuclear physics, which is based on the theoretical assumption that specialists dealing with adverse events with occurring ionizing radiation pass through a variety of specialized courses that include introduction to the theory of nuclear physics.

Population Characteristics in Forensic Genetics
Faltus, Václav
The aim of this paper is to present some methods used in forensic genetics. Forensic genetics is only one part of a wide spectrum of sciences called forensics. It includes identification of victims of natural disasters, mass transportation accidents and industry accidents. It also includes identification of offenders of a crime and determination of paternity. Our current work involves analysis of the genetic data from the Czech population. Therefore and in concordance with other international studies, we focus on methods used in analysis of the genetic profiles of the STR (short tandem repeat) polymorphisms.

Gender statistics - education, labour and earnings
Matějka, Martin ; Langhamrová, Jitka (advisor) ; Löster, Tomáš (referee)
The aim of this bachelor thesis is to analyze the differences between men and women in selected areas of gender statistics-education, labour and earnings. Data for this investigation is garthered from Czech Statistical Office and supported with own questionnaire. Exploration of this areas is carried out by various statistical methods and indicators. The project is divided into three parts. The first part defines basic concepts and explains the principles of statistical methods. The second part examines the gradual evolution of the educational structure of the population since 1950, while also focusing on the detailed development of people in tertiary education. The last part maps the area of labor and earnings, where the population is analyzed from various perspectives in relation to the level achieved gross monthly wages, includes dependence on the highest completed education. All the parts are supplemented by an analysis of data from the questionnaire and inductive judgments on population of Prague and Central Bohemia.

The use of new statistical processes by evaluation of land adjustment realization in Southern Bohemia.
PRŮŠOVÁ, Milena
The thesis deals with evaluation of the projection of complex agrarian arrangement in a selected test set represented by the region of South Bohemia The theoretical part focuses on goals and financial measures of the land consolidation in coherence with the financial support programs. Furthermore, it mentiones some of the primary issues, for example the plan of joint facilities and field routes. The practical part determines the appropriate methods and sets leading to obtaining results both in written and in graphic form. Based on data from the districts of South Bohemia we will a) assess and compare the current state of projection with the percentage of both started and completed complex land arrangements in individual districts, b) asses the main reasons for the implementing these arrangements, c) asses the fragmentation of land in relation to land consolidation and d) asses the costs of land consolidation in individual districts. The goal of this thesis is to provide a comprehensive analysis of projected land arrangements and possible suggestions to improve the current state.

Tree stem diameter and the Moon: a detailed analysis of periodic relationships
Mikulecký, M. ; Střeštík, Jaroslav
Zürcher and Cantiani (Nature, 1998) reported "a strong correlation" between rhythmic fluctuations of diameter of spruce stem on one side and gravimetric lunisolar tides on the ohter. The relationship between stem diameter D and tidal force G has been tested by more exact biometrical means. The 75 diameter and gravity hourly values have been processed by the Halberg cosinor regression and by Bartlett cross-"correlation". The higher peaks of the stem curve are located at 0,7-2,8 hours later than the peaks of the inverted tides. The cross-"correlation" between D and G as the function of time lag shows a 24-hour periodicity with its maximal significant deviation from zero for G delayed after D by 4 hours.
