Approximation by the TLS method: linear data fitting for problems with unprecise models
Pokorná, Kateřina ; Hnětynková, Iveta (advisor) ; Duintjer Tebbens, Erik Jurjen (referee)
In this thesis, we concern ourselves with the linear approximation problem, where errors in both the observation and the data are considered. We focus on the total least squares problem (TLS), which may be used in solving such tasks. We summarise ba- sic theory of the existence and uniqueness of the TLS solution, present the classic TLS algorithm and examine some possible complications, which may appear during its imple- mentation. Furthermore, we shall study the singular value decomposition (SVD), which is used in constructing the TLS solution. As the SVD is rather difficult to compute, we discuss one of the possible methods of approximating only its part necessary for the construction of the TLS solution, the so called singular triplets. This method is based on Golub-Kahan iterative bidiagonalization. Finally, we shall test how the quality of the approximation of the smallest singular triplets influences the computed TLS solution. 1

Title Diagnosis of the nutritional status focused on overweight and obese population. The aim of the work The aim of thesis is to summarize and describe the methods that are used for determining the nutritional status of overweight and obese individuals. Methodology The thesis is a theoretical work with a search character. The main method in the creation of this type of work is a critical content analysis of available resources for the work, and the subsequent comparison of selected findings about diagnosis of nutritional status of overweight and obese population. Results Review article shows that in the clinical practices of identifying a person's nutritional status of overweight or obese at the first contact with the examined using BMI. The orientation index is also used index WHR. Due to the approximate nature of these indexes, however, provides for additional precise examinations body composition, which are for example caliper measurements or bioimpedance. Essential components of a diagnosis of nutritional status are also constitutional typology, family and personal history, immunological examination, biochemical tests and monitoring dietary habits.

Employment of the Czech Republic citizens in other EU member states
Pokorná, Kateřina ; Štefko, Martin (advisor) ; Hůrka, Petr (referee)
The Employment of the Czech citizens in other member states of the European Union The basic aim of my thesis is to analyze possibilities of Czech citizens seeking job in other member states of European Union. The enlargement of EU in 2004 and 2007 opened borders to labour markets of the old EU countries for citizens of new member states. Czech citizens are able to search for a job in most of the states of EU except of Germany and Austria. In my work I concentrate especially on research of United Kingdom. It is a country that opened the labour market for Czech citizens the day our accession to European Union. My thesis is divided into seven chapters. In the first three chapters I analyze the right of free movement of persons, workers and right of settlement. I concentrate on the development from the historical point of view. I also mention the European legislation related to the free movement right. The fourth chapter explains the migration, and the potential of Czech migrant workers. I also describe the reasons for Czech foreign migration. In the fifth chapter I focus on the employment of Czech citizens in other member states in general. I explain where Czechs are able to work and in which circumstances. In the sixth chapter I would like to explain all the possibilities, restrictions, rights and...
Family and school life of children with Obsessive-compulsive disorder
Pokorná, Kateřina ; Lorenzová, Jitka (advisor) ; Hnilica, Karel (referee)
This thesis deals with the complications that brings obsessive-compulsive disorder (OCD) school-age children in the family and school life. It consists of two parts - theoretical and practical. The theoretical part is divided into the seven chapters and is drawn from the knowledge of professional literature and Internet sources. This section consists of basic information about OCD, the etiology, diagnosis, treatment options. The last three chapters deal with the consequences of obsessive-compulsive disorder and problems that OCD brings to family and school life. The practical part is an empirical investigation dealing with the main objective of the work, which is based on an analysis of complications that brings obsessive-compulsive disorder of school-age children in the family and school life. Survey results was achieved through open, axial and selective coding, which allowed delineation create grounded theory. It was found that OCD manifests in childhood and brings negative consequences not only for family but also for the school life of the child, especially in the form of disturbed domestic atmosphere and the inability to concentrate on teaching.

Perinatal and Neonatal Development Parameters in Children of Schizophrenic Mothers - The Effect of Antipsychotic Treatment in Pregnancy (Prevention of Perinatal Complications - Pilot Study)
Pokorná, Kateřina ; Horáček, Jiří (advisor)
This thesis deals with the differences of selected birth characteristics (birth length, birth weight and Apgar score) in children of mothers treated with antipsychotics during pregnancy from the reference population values. It also compares these parameters depending on the type of medication administered during pregnancy. The first part deals with the theoretical introduction to schizophrenia and also describes the obstetric parameters evaluated for all newborns. The second (practical) part is devoted to the analysis of these parameters of children of mothers with schizophrenia, compared with control group in Prague and mutual comparison of the parameters in children of mothers with different medications.
Pre-clinical model of acute promyelocytic leukemia: Study of the anti-leukemic effect induced by ATRA and DNA vaccination
Pokorná, Kateřina
DOCTORAL THESIS 2012 POKORNA Abstract We have used a well characterized transplantable transgenic mouse model which mimics human acute promyelocytic leukemia (APL), both in its biological characteristics and its response to conventional therapeutic drugs. The aim of our study was to better characterize the efficacy of the combined treatment and to determine molecular markers of clinical outcome. We established a minimal residual disease monitoring based on the high sensitivity of detection of PML-RAR transcripts by polymerase chain reaction (PCR) technology in APL mice. We showed that oncogene-specific PCR-based assays allow, like in patients, the diagnosis, follow-up and prediction of disease evolution. Furthermore, PCR assay was used to assess various tissues and organs for the presence of PML-RAR-positive cells in minimal residual disease free long-term survivors. As expected, majority of mice had no measurable tissue level of PML-RAR demonstrating the efficacy of immunotherapy. However, tracking the oncogene-positive cells reveals for the first time that extramedullary PML-RAR-positive cell reservoirs such as the brain may persist and be involved in the leukemia relapse. We aimed at investigating the immune responses involved in the anti-leukemic effect of the combined immutherapy. To evaluate the...
The impact of the process changes on the calculation of the chosen company
POKORNÁ, Kateřina
The purpose of this thesis is to analyze ongoing processes in the selected small and medium-sized enterprise Pokorny - Sítě s.r.o. Further, to find the bottlenecks, suggest how to improve them and to determine whether these improvements were reflected in the calculations of the products which are made in the company Pokorny - Sítě s.r.o. The thesis is divided into two parts: theoretical and practical. The theoretical part is divided into several chapters that describe the basic parts like the process, the process management, the process maps, the process management improvement, the reengineering and others. This section helps us to understand and to describe the basic concepts and definitions related to the process control. The practical part is based on analysis of business processes, observations and interviews with the employees and management of the company Pokorny - Sítě s.r.o and identify the bottlenecks which impede the ongoing processes to continue. After the bottlenecks were identified, the changes of the production process were proposed and applied to the production process of the company. The new layout of the production process led to the elimination of the bottlenecks and the reduction of the production time and also impoved the efficiency and continuity of ongoing production process. Subsequently, new calculation formula was propounded. The new calculation formula provides more information per product (costs - fixed and variable, margin, profit per product etc). The result of the applied changes in the production process is the streamlining production, reduced costs and increased company's profit per product.
