Mapping of behavior and attitudes toward the use of tobacco products among students from 3rd to 5th grades of primary schools in Aš: questionnaire survey
Syrovátková, Kateřina ; Kulhánek, Adam (advisor) ; Vanek, Marián (referee)
Background: Tobacco products are a global phenomenon, among the social and economic classes of the world population. Smoking is also one of the most common forms of risk behaviour among children and adolescents. According to world research, this is also a major problem among children and adolescents. In the ESPAD research, the Czech Republic belongs among the countries with the highest lifetime prevalence of tobacco products among children and adolescents. Objective: The aim of the work was to map the attitudes and use of tobacco products among pupils of the 3rd - 5th classes of selected primary schools in city Aš. Methods: This bachelor thesis research is based on a quantitative method. The research was carried out by a questionnaire survey. Data were analyzed in MS Excel using descriptive statistics methods. Respondents are represented in one third, fourth and fifth class from each primary school in Aš. Data were collected using pencil-paper questionnaire. Overall, 151 students participated in the survey, with an average age of 10.8 years. Results: The results show that 32.5% (n = 151) have at least one life experience with a tobacco product. Cigarettes (22) were placed first in use, followed by e-cigarettes (13). E-cigarettes are not considered by most respondents (82, 6 %) to be an attractive...
Typology of North Korea's Behavior: Analysis of the relations between the US and DPRK
Štroblová, Radka ; Hornát, Jan (advisor) ; Sehnálková, Jana (referee)
Since the accession of Donald J. Trump to the presidency, there have been many significant events that have affected the United States' relations with the Democratic People's Republic of Korea - from testing North Korean nuclear weapons, to verbal insults to both officials, to a historical meeting of the leaders of both Korean states in the demilitarized zone, a joint performance by South Korean and North Korean athletes at the Pyongyang Winter Olympics, to the historic Singapore Summit between Donald Trump and Kim Jong-un. However, the second meeting of both representatives in Hanoi ended prematurely - without signing the planned joint statement. Relations between the United States of America and the Democratic People's Republic of Korea are constantly developing. The main theme of the talks in the past was the complete, verifiable and irreversible denuclearization of the Korean Peninsula to ensure lasting peace and stability for the region. The North Korean nuclear program and efforts to reduce it have thus become a major issue in multilateral negotiations, with the Republic of Korea, China, Russia and Japan participating in addition to the United States and North Korea. North Korea, however, often sabotaged the talks and the period of cooperation was interrupted by provocations and hostile...
Ecology and behaviour of an enigmatic fossorial rodent, the giant root-rat (Tachyoryctes macrocephalus), endemic to the Afroalpine habitat in the Bale Mountains, Ethiopia
The research in this thesis concerns with the ecology and behaviour of an endangered fossorial rodent, the giant root-rat (Tachyoryctes macrocephalus), in the Afroalpine ecosystem of the Bale Mountains, Ethiopia, and the results are discussed in relation with available ecological data on other fossorial/subterranean rodents. Firstly, this theses is focused on investigating the ecological role of the giant root-rat. The evaluation of root-rat's impact on various ecosystem features, in the first study, highly contributed to the knowledge not only about the species itself but also about the functioning of the ecosystem it inhabits. In fact, the results of the study indicated that the giant root-rat acts as an ecosystem engineer in the Afroalpine grasslands. Secondly, this thesis involves a pilot radio-telemetry study on the giant root-rat focusing on its temporal and spatial activity. Specifically, the results of the second study brought new light to giant root-rats' daily activity, its pattern, amount and seasonal change demonstrating the difference in activity patterns between strictly subterranean rodents and subterranean rodents with aboveground habits such as the giant root-rat. In the third study, we described the space-use patterns of the giant root-rat and revealed several trends in its spatial behaviour that can serve as a strategy to cope with the harsh and changeable environmental conditions in the Afroalpine ecosystem.

Chování vodních organismů a kontaminace vodních toků? nechtěná léčba deprese a nespavosti u raků
MAREŠ, Josef
This bachelor thesis evaluates the possible effects of pharmaceutically active compounds on non-target fresh water organisms and the risks connected with them. As model organism was used parthenogenetically reproducing non-native marbled crayfish, which were exposed to a mix of five commonly used drugs and one illicit drug - tramadol, citalopram, sertraline, venlafaxine, oxazepam and methamphetamine. The concentration was 1 microgram.l-1 for each of the tested compounds. The main part of the experiment was based on monitoring the behaviour of the exposed and control group of crayfish in arenas with or without shelter. Prior experiment crayfish were exposed for three-weeks to the mixture of compounds mentioned above. The results were analysed in the programme EthoVisionXT and later also statistically evaluated. In the system with available shelters the observed parameters (distance moved and activity) showed significant differences, where the exposed group walked significantly larger distances and was considerably more active than the control group. Exposed group also spent significantly more time outside the shelter. The results in the system without shelter were almost the opposite. The distance moved, velocity and activity were significantly different. The exposed crayfish showed considerably lower activity, velocity and moved shorter distances. The results of this experiment prove that the mixture of monitored compounds can have a significant impact on the behaviour of non-target fresh water organisms. The compounds had a softening effect and can affect sensory receptors of the exposed crayfish, which can have a significant impact on the populations in open waters.
Vliv herbicidu s-metolachloru na raná vývojová stádia raka mramorovaného
S-metolachlor is a substance belonging to the group of herbicides, widely used in agriculture to protect crops. This substance with the chemical composition C15H22CINO2 and is used as the pre-emergent herbicides to control unwanted weeds. The aim of this work was to evaluate the influence of s-metolachlor on mortality, behavior, growth, ontogenetic development, oxidative stress level and activity of antioxidant enzymes of early developmental stages of marbled crayfish (Procambarus fallax f. virginalis). The effect of s-metolachlor was evaluated on the basis of embryo-larval toxicity test. Early developmental stages of crayfish were exposed to three concentrations of s-metolachlor, 1.1 micrograms/l, 11 micrograms/l and 110 micrograms/l for 45 days. All tested concentrations significant showed higher mortality, delay of ontogenetic development, lower growth and changes in behavior (total movement distance and movement speed). Moreover, significant decrease in catalase, glutathione-s-transferase, superoxide dismutase concentration, and reduced glutathione levels at the two higher test concentrations (11 micrograms/l and 110 micrograms/l) of s-metolachlor were observed. No significant changes in oxidative damage (TBARS levels) were observed in all the tested groups. Based on the results of this study, early developmental stages of marbled crayfish can be recommended as suitable organisms for toxicity test and their use for biomonitoring of the aquatic environment by herbicides.
The impact of the behaviour of individuals addicted to drugs on the Romany community
The diploma thesis deals with the drug addiction issue, the circumstances that lead to drug addiction and most importantly the impact the drug addiction has on an individual. It also describes the behaviour of the drug addicted in different life situations and the impact of such behaviour; specifically the impact of behaviour of the drug addicted Romany on functioning of Romany families and communities. The aim of this thesis is to present drug-related issues of the Romany ethnic group, specific aspects of the behaviour of the drug addicted and the impact of such behaviour on their communities. Terminology related to the topic is defined and further described and drug addiction related issues of the Romany ethnic group are specified. As a part of the analysis there are semi-structured interviews which aim to describe, as authentically as possible, behaviour of the drug addicted Romany and to help people understand what kind of impact the Romany community perceive as the most urgent. Among the most important there are: the negative and condemning attitude of the older generation towards the drug addicted members; financial burden of the families of the drug addicted and prevailing negative attitude of the majority society towards the Romany as a whole, which is strengthened by the behaviour of the drug addicted and by higher rate of criminality among them.
Transfer from the lower to upper secondary school from the point of view of teaching mathematics
Rašovský, Matěj ; Vondrová, Naďa (advisor) ; Novotná, Jarmila (referee)
This thesis is aimed on transfer of pupils from lower to upper secondary school from the point of view of mathematics. It was chosen three pupils which attended the same lower secondary school and transfer to the same upper secondary school. Using questionnaires and mathematical test, which were given in September 2014 and January 2015, was reviewed their transfer from the point of view pedagogical-psychical and mathematical. These questionnaires were given to the teachers also. This transfer was mostly negative for pupils. The level of knowledge of mathematics was the same or even worse. It is caused by different teacher's access to teaching mathematics. We could hope that this situation will be changed in a couple months. KEYWORDS: Education, transfer, learning, school educational program, personality, behavior
Use of the anchoring effect in marketing communication
Režný, Michal ; Vranka, Marek (advisor) ; Báča, Ladislav (referee)
This bachelor thesis is dedicated to the study of the anchoring effect, one of the most common cognitive biases, and its potential use in marketing communication. The first section of the first part provides a theoretical summary of the anchoring effect as a psychological phenomenon in the form in which it was defined by Amos Tversky and Daniel Kahneman in the early 1970s. It addresses the possible explanations of anchoring and also gives a brief introduction to related cognitive biases, understanding of which is crucial for further orientation in the use of anchoring in marketing communication. The main body of the first part is formed by a theoretical research of academic literature and consequently conducted studies and experiments. The terminological discrepancies between fields when it comes to anchoring in marketing communication are dealt with special attention. A considerable part of this section is dedicated to the different types of use of anchoring in marketing communication. The second part of this paper is an empirical one. It describes an experiment conducted by the author of this work with the objective of studying the effect of anchoring and its usability in practice on the example of fictitious car commercials. The results of the experiment suggest that while there is an evidence...
Use of Primate Expositions in Education at Elementary School
Vilímová, Tereza ; Vančata, Václav (advisor) ; Hlaváčová, Lucie (referee)
This thesis proposes a possibility of using the exposition of primates in the Prague zoo during the school excursion for pupils of the 7th or 8th grade of elementary school. The thesis is divided into individual parts that theoretically analyse the importance of excursions for education and subsequently it is practically focused on facilitating the smooth course of the excursion and other activities that precede the excursion or follow it freely. In the thesis there is the general sorting of primates into individual species described in detail and there is provided basic information about primates that are bred in the Prague zoo. Further, possible excursion trail including individual expositions where the particular animals can be seen is described in detail. The main objective was to provide teachers with detailed instructions on how to make the excursion so it is successful. The purpose of the work was also to create materials which help to actively memorize the information provided and to raise children's interest in such an interesting animal species as the primates. With regard to the fact that most primates are currently threatened by extinction in their natural habitat, the theme of the excursion is closely linked to environmental issues and a responsible approach to the use of natural...
