Problems of leisure time of children in the second stage of basic school and compensation school load
LEŽÁKOVÁ, Petra
The topic of my bachelor thesis is focused on middle school children and spending their free time and compensation of schoolwork. Nowadays, there is a large amount of extracurricular pursuits which children can follow in their free time. They can attend various leisure-time centres, centres for children and youth, school centres and clubs and many others providing leisure-time activities. These centres primarily offer sport activities, afternoon clubs, educational trips and a great deal of other pursuits. Children also pass their leisure time passively, mostly watching TV or using a computer. This is the reason why this issue should be dealt with. We should help children to fill their free time productively and effectively so that they would be able to use it to pursue their hobbies and interests. There are a lot of factors which can considerably influence spending free time such as a family, friends and peers but also teachers or a school which a child attends and many others.My work is divided into two parts. First of them is the theoretical part.section of my bachelor thesis concerns compensation of schoolwork. Second part of the thesis, the practical one, is based on a quantitative research consisting of questionnaires concerning leisure preferences of middle school children. Results of the above-mentioned questionnaires are compiled into graphs and presented in this work. The primary aim of this thesis was to monitor how the youth of today passes their leisure time. To accomplish the objective, four hypotheses were suggested: Hypothesis 1: Today?s children prefer spending their free time passively rather than actively Hypothesis 2: When spending free time passively, children prefer using computer to watching TV Hypothesis 3: Sport activities are more popular with boys rather than girls Hypothesis 4: Pupils prefer playing teams sports to doing individual sports

Computation of relative function of kydney at dynamic scintigraphy - influence of time period applied for computation.
HRTÁŇOVÁ, Jana
The topic of my bachelor thesis is a computation of relative renal function at dynamic scintigraphy and an influence of the time period applied for computation. The main aim of the thesis is to establish if the usage of two different time periods for computation of relative function of kidneys at dynamic scintigraphy of kidneys has any influence on computed function. Precisely, whether the choice of time period affects the result of processing the study is acquired by dynamic scintigraphy of kidneys. Expressed hypothesis assumes that time periods between 60s and 180s which were chosen for the calculation have not the influence on calculated relative function. Dynamic scintigraphy of kidneys enabling to display function of kidney´s ability to clean blood from the observed substance and consider possible defect of kidney excretion, it is the important method of examination mainly by children patients which are the vast majority of examined patients. For the hypothesis confirmation, there was created a reference file. This file consists of children patients who were examined by dynamic scintigraphy of kidneys in the Department of Nuclear Medicine Hospital in Czech Budejovice. With a help of program of dynamic scintigraphy the relative function of kidney was computed and defined by the percentage portion of each kidney on the whole renal function. The different time periods were used for the function curve for the computation. The function curve is designed like a graph from the marked region of interest and it is the result of computer processing data which were obtained from the scintigraphic study. From obtained values, the tested criteria are subsequently determined by statistical calculations they are confirmed and given as a zero hypothesis.

Bone traumatology
DOLEŽALOVÁ, Barbora
The subject of the bachelor?s work is ?Bone traumatology?, which is in health institutions of the Czech Republic classified forefront in diagnostics thanks to skiagraphy. In nowadays medicine new technologies are used permanently. Dealed with conventional radiology, its the biggest expansion came in the beginning of 20 century, when some new radiation X (X-ray radiation) was discovered. Just thanks to this discovery the new era of permanently developing new methods for diagnostics started. The theoretical part of the work is concerned with anatomy of a bone together with traumatology. Next there is a part dedicated to some basic facts about X-ray radiation. In this work is also described skiagraphy, in which I deal more with the matters of film material and digital radiology. In hospitals and in majority of workplaces we meet more and more digitalisation of a system and a transition from film materials to various detectors (an image intensifier, semiconductor detectors, photostimulable phosphor plate etc.,). The aim of the work is to analyse a quotient of skiagraphy of bone traumatology in particular age groups. The hypotheses of this bachelor?s work were defined this way: in radiodiagnostic wards predominates skiagraphy of an axial skeleton over other radiographic diagnostics (soft tissues- lungs, a heart, an abdomen). The most numerous group of examined people are children at the age to 15. The practical part of the work provides information dealed mainly with numbers of radiographic exeminations performed in the X-ray workplace in Týn nad Vltavou from 2009 to 2011. These examinations were concerned with bones, but also soft tissues (a heart, lungs, an abdomen). The data were found out from operative diaries and computer systems. In this work there were compared patients of particular age groups: - in the number of radiographic examinations in an observed period (2009-2011) - in the number of radiographicly, examined particular zones of a human body (a hearth+lungs, a spine, an upper limb, a lower limb, a skull, ribs+a breastbone and an abdomen). Further data which was obtained from the internet portal of Institute of health information and statistics of the Czech Republic (ÚZIS ČR) were worked up. Examinations were tested through the use of imaging technologies in the Czech Rebublic and Southern Bohemia and a number of radiographic examined particular zones of a human body (a breast,a lower limb, an upper limb, a spine, bone radiology and an abdomen) in Southern Bohemia from 2009 to 2011. All the obtained data I worked up into particular graphs which are found in the chapter ?Quantitative research?. In the chapter ?Discussion? particular graphs are described and are complemented with my personal hypothesis and opinions of a radiology asistent from X-ray workplace in Týn nad Vltavou. The results of the work prove that the aim of the work was realised. Defined hypothesis no.1: in radiological workplaces skiagraphy of an axial skeleton prevails over the other radiographic diagnosis (soft tissues- a heart, lungs, an abdomen) was confirmed, however hypothesis no.2: the most numerous group of examined are children to the age of 15 was not succesful to confirm. In the chapter ?Conclusion? I summarised the results of the work, which will help as a supplemental statistical material with a more detailed structure in X-ray workplace in Týn nad Vltavou. The theoretical part of the work can be used as a tutorial material not only in the subject of the radiological assistant.

Comparison of level total cholesterol in serum for residents from Pilsen and Czech Budweis provided similar eating habits
FRAITOVÁ, Lucie
Measuring cholesterol is considered as a screening test used primarily to determine cardiovascular risk and monitoring lipid-lowering therapy. Since this is a screening examination, there is a need for further laboratory tests - the lipid profile (HDL cholesterol, LDL cholesterol, triglycerides). Patients who get examined as a part of lipid-lowering therapy should follow a diet. These patiens need to be examined more frequently. Population of Czech Republic is considered at risk of early occurrence of atherosclerosis and its complications. Every year in the Czech Republic nearly 60 000 people die from cardiac and vascular disease. Cardiovascular disease increasingly affects younger age group. They are also a cause of disability of people of working age. One of the main indicators is high level of cholesterol. Accurate and precise measurement of blood cholesterol plays a role in the reduction of morbidity and mortality of people with cardio vascular disease. The aim of this thesis is to: 1) Measure the total cholesterol sample population of Plzeň and České Budějovice 2) Compare and find differences in serum total cholesterol in both locations In the theoretical part of the thesis I was interested in what foods increase cholesterol and what foods can reduce high cholesterol. Furthermore, the theoretical part describes diseases that may occur during hypercholesterolemia. The basic ones include atherosclerosis and its complications, which include heart disease or stroke. Preanalytical factor that may significantly affect laboratory tests are described in this part too. The practical part describes everything from an intake of biological material in the laboratory through the preparation (centrifugation, creating aliquots) to insertion of a secondary sample into the analytical device. Research for the thesis was conducted in the biochemical laboratory of synlab czech s.r.o. in České Budějovice. In this part I investigate ? under supervision ? a total of 100 samples of venous blood from people of Plzeň and České Budějovice. I determined the total cholesterol in serum. Cobas Integra 800 automatic biochemical analyzer was used for the examination of the biological material. In routine practice enzymatic methods are used to determine levels of cholesterol. Cholesterol esters are converted by cholesterol esterase into free cholesterol and fatty acids. Free cholesterol is oxidized by cholesterol oxidase to form cholestenone and hydrogen peroxide. The resultant hydrogen peroxide reacts with 4-aminoantipyrine and phenol to form a red color and water. The color intensity is directly proportional to the concentration of cholesterol and is measured by absorption spectrophotometry at 512 nm.Measured laboratory results were statistically processed and neatly sorted into tables and graphs using the computer program. Data from Plzeň and České Budějovice were sorted according to gender and evaluated using graphs. The data sets were then compared to each other and the difference in cholesterol levels was registered. All the results are in the table and graphs. Hypercholesterolemia was detected in 29 samples from Plzeň and 27 from České Budějovice.

Assessment of differential number of leukocytes in automatic analyzer and microscopically
BAMBULOVÁ, Iva
Evaluation of blood count with differential leukocyte budget is a basic haematological test. From a diagnostic point of view is the information about the exact number of leukocytes and their percentage representation in the patient's blood very valuable as well as a range of informations on the effect of disease states. In my bachelor´s thesis I devote to instrumentative and microscopic examination of the differential leukocyte budget and their comparing in terms of difficulty and obtaining the most accurate results. Nowadays, with the development of science and technology are used to determine differential leukocyte budget modern haematological analyzers, but the manual setting by using a microscope remains the basis of good work in haematological laboratory. The goal of each laboratory determination is to produce accurate results for clinical use. The analyzes are mostly automatic and their advantages are faster pace of analysis, accuracy, reliability and need of small volume of sample. The main objective of my thesis is to evaluate the distinction by using two different methods, microscopical and instrumentative. The thesis is traditionally divided into theoretical and practical part. The theoretic part of the thesis explains the meaning of the differential leukocyte count, there is a detailed morfology description of different leukocyte types. I mentioned the non-neoplastic and neoplastic changes in the number of leukocytes. Last but not least, there is an overview of laboratory methods that are used for blood counts in routine haematological laboratory. To determine differential leukocyte budget is used optical method, electrical impedance method, cytochemical method or digital morphology. The practical part describes the examination methodology of the differential leukocyte budget, which I have used in this work. I made a blood smear by microscopic assessment, which I dyed according the instructions. Preparates are viewed with oil immersion under a light microscope. To record different leukocyte types are used recording devices - leucomats. I made automatic assessment of differential leukocyte budget in 5 - population haematological analyzer Sysmex XE - 2100 based on the principle of flow cytometry with sample measurements from the feeder closed or open way. Examination of differential leukocyte budgets was realized in biochemical and haematological laboratory synlab czech s.r.o in Czech Budweis. Here I investigated 100 randomly selected patient samples of venous blood under the proffesional supervision and I compared the differential leukocyte budgets and differences between methods. I investigated samples in April and May of 2012. Results obtained by microscopic examination and by measurements on analyzer were statistically compiled into tables and graphs in a computer program. In the graphical representation comparing the differential cell counts in 100 samples of the budget of the analyzer under a microscope. I set the hypothesis that the numbers of microscopic differentials equal to those of the automatic analyzer. Laboratory results were obtained by the measurement and that results were interpreted after consultation with the supervisor. Based on the results, I rejected the hypothesis. Own laboratory investigation showed that classic microscopic assessment has essential importance in the analysis of pathological cells. It also depends on the experience of the laboratory worker. The advantages of the haematologic analyzer are particularly rapid analysis, accuracy and need of small volume of biological sample. During the practical part of the thesis I gained practical skills in working with biological material and I embraced the principles of laboratory methods. The results of my work can be used widely in clinical laboratories in assessing the advantages and disadvantages of relationships between monitored by analytical methods.

Generation of computer program for specific-heat analysis
Majer, Peter ; Ježek, Lukáš (referee) ; Javorský, Pavel (advisor)
This work is about to design and implement the speci c-heat analysis application. The application consists of two parts: the rst one provides for data manipulation, the second one plots a graph. The data manipulation part resembles a spreadsheet program - each column in a dataset stands for one measurement. Columns containing a temperature data could be used for a speci c-heat calculation. This calculation is based on this model functions: conduction electrons consideration, phonon contribution and Schottky contribution. It is also possible to arrange your own formulas by using basic mathematical operations (namely summation, substraction, multiplication and division). Fitting data to the selected model is also possible. Levenberg-Marquardt and simplex method are being used for it. Hamiltonian matrix used for energy levels calculations of magnetic ions in crystalline electric elds could also be calculated. The application is written in C# programming language.

Cell shape simulation using cytoskeleton model
Horáček, Jaroslav ; Bílý, Tomáš (referee) ; Bálek, Martin (advisor)
This work is focused on computer modelling of cells' behavior. Emphasis is layed on simulating of cell shaping. The goal is to design theoretical structure, which suitably represents cytoskeleton of cell. Our model is based on Zygotic graph. It defines cell reactions to incoming stimulation from environment. Unlike previous models we newly add Fill graph and Granary graph to the Zygotic graph. In order to modelling of cell shaping we define membrane flexibility. We also define mechanism of Cytoplasmatic pulse. It is necessary for amoeboid movement modelling. We added new structure called Granary, which represents storage ability of cell. We use our model to simulate movement of amoeba cell. Another example shows white blood cell moving through blood vessel wall. We also attempt to simulate growth of cells inside closed environment.

3D Micromodels of Porous Structures
Pražák, Josef
Speaking about modeling in technical sciences, we have in mind an analysis of mathematical (computational) or physical analogies of objects to be studied. Physical modeling means a systematic building of physical objects heaving some analogy with the studied physical reality. For the models of porous structures, the notion micromodels has been introduced. The micro- means that the model represents only a small fraction of real porous structure and that some essential schematization of reality is included. The difference between a micromodel and a simple probe of a natural porous material (a small volume of soil, sand, etc.) consist in the fact that some exact geometrical information is ahead. Very often, the real porous space is schematized into a regular graph network. The Lenormand´s micromodels are 2D objects where a random square network has been cut in a sophisticated way into a layer of resin between two layers of plexiglass.
