Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Gates - Sound instalation as an intersection of intermedia paradigms
Rataj, Jakub ; BARTOŇ, Hanuš (advisor) ; TROJAN, Jan (referee)
This work treats about the permeation of three spheres (sound instalation, soundscape and physical computing) and their influence for creating a proper piece of art ? sound instalation The Gates. First I treat about the sound instalation from different points of view ? historical context, the work with time, sound and space, technical and visual elaboration. In the end of the first part I describe the concept of my own sound instalation The Gates. In the second part I treat about the concept of soundscape and its influence for selecting the sound material. The last part treats about physical computing as an instrument for the realization of the sound instalation The Gates and as an instrument for enlarging the possibilities of the intermedial synthesis in a more general point of view.

Inclusive education opportunities for children with physical disability in nursery schools in South Bohemian region
HAIDEROVÁ, Lenka
This thesis focuses on inclusive education of children with physical disability in nursery schools in South Bohemian region. The authoress describes in theoretic part of its thesis individual kind of congenital and acquired physical disabilities, next she compares inclusive education with integration and present situation of inclusive education in Czech Republic, including looking at this education in the past. She writes about child development in preschool age too, and this of aspect his motor and cognitive development, socialization in nursery school and about specialty children's psychology of a child with physical disability, which differs from development healthy child. In practical part the authoress concentrates on the opinions of selected educational staffs (teacher) and parents regarding this phenomenon in education. Research sample contains nine respondents, of which five teachers and four parents, for teachers were prepared eleven questions and for parents nine. She used as a method of research semi structured interview, that she could ask for details and digress from prearranged question. The authoress wanted to know with this research, if these two groups would be willing to support this education and what they are the reasons for this. Next she ascertained attitudes of parents of children with physical disability and benefit of this education for children with physical disability and for other children, healthy. She donated to compare these opinions between educational staffs and parents too. Finally, she tries to compare opinions between educational staff and parent from one nursery school.

Lifestyle of patients with peripheral arterial disease before and after surgery
REZKOVÁ, Helena
Theoretical background: Peripheral arterial disease is a serious disease of Loir limb arteries which originates from atherosclerosis. The theoretical part deals with the lifestyle. There are mentioned basic risk factors of chronic forms. Further described are the pathophysiology changes generated on the basis of atherosclerosis and related causes for the origin of the disease. Subsequently there are explained methods of classification, developed clinical symptoms, diagnosis and therapy. This section also looks at the role of a nurse in the care of patients with peripheral arterial disease. Objectives: The aim of this work was to evaluate how patients with peripheral arterial disease changed their lifestyle after invasive vascular surgery. There were provided the following research questions: How do patients with peripheral arterial disease approach to the prevention of risk factors? What is in patients with peripheral arterial disease the main impuls for the possible change of their lifestyle? What influences surgery patient's attitude to risk factors for peripheral arterial disease? How crucial is a lifestyle change in patients after surgery for peripheral arterial disease? Methods: The theoretical part is processed using expert sources. The empirical part of the theses was processed using qualitative research. The chosen technique for data collection was semi-structured interviews with patients, with prepared open questions. The research was done in several phases - the first interview was conducted at the patient admission department (before surgery), followed by the next phase after three months, and 6 months after surgery. The interviews were recorded on a prepared form, then transcribed into electronic form and analyzed by open coding method. Results: The research showed that surgery can sometimes be triggered by changes in the patient's lifestyle. The first interviews in the preoperative period focused on how respondents felt, what was their lifestyle before surgery for atherosclerotic changes of the lower extremities. One of the questions was focused on patient knowledge about risk factors for the development of PAD and possible prevention. The second phase of interviews took place 3 months after the surgery. It dealt with the question about the respndents´ lifestyle, the respondents in the postoperative period, whether there were any changes. Some positive changes occurred in eating and there were some changes in doing physical activity. The third stage was carried out six months after surgery, again in order to detect changes in lifestyle. Minor changes came in smoking habits, the issue of diet and physical aktivity. Questions were also focused on the psychological level. We found out who helped patients and what was most motivating in implementing changes. In the conclusion/summing up question the patients marked themselves ow they managed to make a change. Conclusion: The number of patients with peripheral arterial disease and other cardiovascular diseases is increasing. The basis is the start to modify risk factors, namely tobacco use,dietary habits, physical activity. The medical staff members participate on changes in patients´ lifestyle by appropriate education. The problem occurs when the patient despite the support of close people can not cope to carry a twist in their life. There should a medical staff member offer a professional help to deal with this important step. Practical use: The aim is to draw attention to the expansion of education about lifestyle changes for patients diagnosed with PAD also in the postoperative period. Patients who are released to home care should receive enough information that would convince them to change their attitude towards their health, and that surgery is only one of the ways to prevent further attacks and complications. Results can improve communication with patients and focus on increasing their awareness and possibly offer assistance.

Role of physical activity in the prevention of childhood obesity
VRTALOVÁ, Jana
The thesis deals with physical activity in the prevention of childhood obesity. It is focused on children, namely pupils of the eighth and ninith grades of elementary school. Obesity is responsible for more human lives than both of the world wars and if we want this epidemic of obesity and problems associated with inactivity minimized, we have to start where it is most efficient and that is with children. The main objective is to explore physical activity in a selected group of pupils. Partial aim is to determine the prevalence of overweight and obesity in the investigated group of students using somatometric measurements in the selected location. Another objective is to determine how many of childrens parents did sports in the past or actualy do sports. The final goal is to prepare educational material for students about the importance of physical activity. The work is divided into two parts theoretical and practical. The theoretical part was compiled as a secondary data analysis. Sources of data and information originated from the Czech Republic and abroad in the form of scholarly books, journals and electronic resources. The contents of the theoretical part is focused on explenation of terms such as obesity, its consequences, complications, ways to prevent obesity, physical activity, appropriate kinds of physical activity and its effects on the human body. Distinctive part is the chapter dealing with the myths of obesity some of them are really surprising. The second part is practical part and includes its own research. The investigation was conducted in a primary school Komenského alej in Žatec for pupils of the eighth and ninth grades. File featured 107 pupils. The research was conducted as a quantitative survey complemented by measurements of somatometric indicators. The data were collected using a custom non-standardized questionnaire. The questionnaire contained 14 questions and two columns separated by line for recording the exact weight and height. We checked these data at pre-agreed periods.

Resistance of cole vegetable cultivars against Plasmodiophora brassicae pathotypes in Czech Republic
Zacharová, Lea ; Kazda, Jan (advisor) ; Gerhard, Gerhard (referee)
Clubroot disease of crucifer plants is caused by a pathogen Plasmodiophora brassicae (Wor.). It is counted among the most common and most serious diseases that attack not only rape, but also, for example, head cabbage, cauliflower, broccoli and other kinds of cabbage vegetables.
Plasmodiophora brassicae is descirebed as a very durable and well-developed body in this thesis. Physical, chemical and biological components of the soil environment are in the thesis associated with an effect on survival, growth and reproduction of this microbe. Obviously, Plasmodiophora's brassicae successfulness is given due to its resting spores and because of them the microbe is able to survive in a soil for years.
The experimental part of my thesis is focused on a testing of resistance of selected cultivars against Plasmodiophora brassicae. Each variety were grown under the control within conditions in the greenhouse. To evaluate the degree of a damage of the plants scale of Buzacki (1975), Strelkov et al. (2007) were applied, the index of an invasion was calculated based on these scales.
Cultivars were exposed to a pathotype 6 and as a control variety was used the cultivar Granaat. The results had shown the most susceptible respond of a cultivar red cabbage F1 Loder and other varieties tested had confirmed their resistance to Plasmodiophora brassicae.
