Image registration
Jindra, Jakub ; Jiřík, Radovan (referee) ; Krátká, Lucie (advisor)
This bachelor thesis deals with various methods of image registration in the medical treatment. The criterias are elaborated for selecting the correct method of registration. This work describes parameters for proper transformation, identification, registration proces, a final assessment of registration for its approval and the corresponding evaluation. Some basic programs have already concerned with image registration and they are accompanied by basic information. This semester thesis also describes the basics of working with MRI and the creation of anatomical atlas from the magnetic resonation rat’s brain. In conclusion is described the creation of a simple graphical interface for viewing images of brain obtained from the magnetic resonance. Furthermore, the work deals with the registration of images according freely available programs and the related system of evaluation of these results. The scoring system is processed in a graphical users interface Matlab, where is used histograms, mosaic and evaluation using the cross.

Stress detection
Jindra, Jakub ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
Stress detection based on non-EEG physiological data can be useful for monitoring drivers, pilots, and also for monitoring of people in ordinary situation, where standard EEG monitoring is unsuitable. This work uses Non-EEG database freely available from Physionet. The database contains records of heart rate, saturation of blood oxygen, motion, a conductance of skin and temperature recorded for 3 type of stress alternated with relax state. Two final models were created in this thesis. First model for Binary classification stress/relax, second for classification of 4 different type of psychical state. Best results were reached using model created by decision tree algorithm with 8 features for binary classification and with 8 features for classification of 4 psychical state. Accuracy of final models is aproximately 95 % for binary model and 99 % for classification of 4 psychical state. All algorithms were implemented in Python.

Entity
Jindra, Jakub ; Turek, Filip (referee) ; Hájek, Václav (advisor)
Informace může vytvářet určité entropické krajiny. Entropická krajina je složená ze zdrojů informace. Zdroj může být informačně přínosný nebo úplně zbytečný. Dobrý zdroj vytváří nízkou entropii, vysoký náboj, a špatný zdroj entropii vysokou s nízkým informačním nábojem. Touto optikou pak můžeme vidět fiktivní krajinu, která se kolem nás nalézá. Entita je její vizualizací, vytváří útesy, tam kde byly roviny, hory zkoncentrované informace a měsíční údolí s nulovou hodnotou.

Evaluation of Social Competencies of Hluboká nad Vltavou Police Officers from the Clients' Point of View
JINDRA, Jaromír
The thesis examines the performance of social competences by members of the Police of the Czech Republic and evaluates it from the perspective of clients. The clear focus of the police is working with people who are often in a difficult social situation. In doing so, they encounter perhaps all types of clients affected by complex problems, such as domestic violence, social exclusion, substance abuse, family pathology, dealing with families, individuals, the elderly, the sick, etc. In the Czech environment, however, the social competences of police officers are not researched, evaluated and regulated in any way. In this case, the management and organisation of the police relies only on the personal approach of the worker without wider research and addressing the issue. This thesis attempts to link the quite obvious relationship between police performance and social work, offering a comparison with the organisation and management of this issue in foreign practice. The aim of the thesis was to determine the level of satisfaction with the performance of social competences among the police officers of Hluboká nad Vltavou from the perspective of their clients. To achieve this, three hypotheses were set, examining client satisfaction with social competence and satisfaction with the services provided, then examining this in terms of the client's position in which they deal with the police, and finally in the context of demographic indicators. The results of the research confirmed a clear relationship between the level of satisfaction with social competences and the services provided. On the contrary, it was refuted that satisfaction was significantly influenced by age, educational attainment, gender or the position in which the client interacts with the police. The anticipated contribution to practice is in interpreting how the public actually perceives the social skills of the police. The results can serve as a basis for developing and modifying these skills and for practically linking social work with the performance of the riot police service, especially through insights from foreign literature and supervision.

Substance use and evaluation of prevention activities of students of Secondary School Vimperk
JINDRA, Jaromír
This work deals with the use of addictive substances by high school students and with the evaluation of preventive activities. I´ts task is to find out the opinions and experiences of students with addictive substances and preventive activities. There was chosen following goal of the work: "Identification of risk factors of students behavior due to substance use and evaluation of primary prevention of risk behavior." The work is divided into theoretical and practical parts, where the theoretical part briefly describes the prevention of risky behavior and the most commonly used addictive substances. Specifically, the areas of risk and protective factors, primary prevention of risky behavior, school and drug prevention, the effects of addictive substances and their relationship to risky behavior were described. The practical part is processed with a quantitative strategy by the statistical method, where the technique of data collection was used a questionnaire survey conducted among students of Vimperk High School. The results of the research show, that the most fundamental risk factor affecting students is their closest social environment, their family, friends and peers. Prevention is effective in the use of hard drugs, which is not the case with tobacco cigarettes, alcoholic beverages and marijuana. The results of the work can serve as a mapping of the current situation of risky behavior due to the use of addictive substances used for further research and as a comparative material. They can also serve as a basis for practical use in creating prevention programs and to improve primary prevention.

Stress Detection On Non-Eeg Physiolog Data
Jindra, Jakub
Stress detection based on Non-EEG physiological data can be useful for monitoring drivers, pilots, workers, and other subjects, where standard EEG monitoring is unsuitable. This work uses Non-EEG database freely available from Physionet. The database contains records of heart rate, saturation of blood oxygen, motion, a conductance of skin and temperature. Model for automatic detection of stress was learned on these data. Best results were reached using a model of a decision tree with 25 features. The accuracy of the resulting model is approximately 93 %.
