Influence of the time interval from the radiopharmaceutical administration on the bone / background activity ratio in the bone scintigraphy
 ZAHOŘOVÁ, Tereza
Influence of the time interval from the application of radiopharmaceutical on the activity ratio of bone/backround during the skeletal scintigraphy. The presented thesis aims to demonstrate the effect of the selected time interval from the application of radiopharmaceutical until the start of whole body skeletal scintigraphy on the quality of examination of patients at the department of nuclear medicine at the Clinic of imaging methods in FN Pilsen. The ratio between the background and bone activity of patients will vary with the length of the interval between the application of radiopharmaceuticals and the beginning of imaging. We expect that with prolonging of the time interval the ratio between the background and bone activity will increase, which means a higher quality of your imaging in practise. The hypothesis of this thesis expects a differentiation of ratio between the background and bone activity depending on the time of initiating whole body scintigraphy from the time of application of radiopharmaceuticals. To determine the ratio value a reference file of males aged 25-65 years (year of birth from 1951 to 1991, the year of examination from 2013 to 2016), weighing 65-95 kg was created, where scintigraphy does not show pathology in the examined area of the skeleton or in the soft tissues on the left thigh. These patients were divided into two groups according to the time intervals between the application and the beginning of the whole body skeletal scintigraphy. The first group consists of 30 patients who were examined less than 120 minutes after the application of the radiopharmaceutical. The second group consists of 30 patients who were examined more than 120 minutes after the application of the radiopharmaceutical. Using the ROI technique, values from the areas L5, right femur and soft tissue structures on the left thigh are obtained. These values are then used to calculate the time intervals on the activity ratio of bone/backround and verify the hypothesis, which assumes that the ratio values between the above mentioned groups will be different. This difference should prove that a longer time interval between the application of the radiopharmaceutical and the beginning of scintigraphy will bring a higher quality of scintigraphic imaging. This qualitative factor will be beneficial both for patients and their physicians who have to describe these scintigrams.

Subjective perception of behavior change in children of preschool age
 ZÁHOROVÁ, Tereza
This thesis slew change behavior in preschool children since 1989, resulting in a goal thesis and to determine and determine if the behavior of preschool children has changed and in which way since 1989 The thesis is divided into theoretical and practical part. In the theoretical part I focused on the historical development of preschool education since 1989, further to the child in the preschool age, influences and social factors that influence the child's behavior and in the last row on the value of preschool children. In the second, the practical part of my thesis was a qualitative research method. Data were collected by interview using the By interview using semi-structured technique of interview, which were conducted with five communication partners. I asked five kindergarten teachers, who have more than twenty years of experience in the field of preschool education and who still teaches in kindergartens. Interviews lasted between 30-60 minutes and took place in an environment of kindergarten or in an environmentwhich was choosen by communication partners. The aim of my thesis was to explore changes in the behavior of preschool children since 1989. In relation to established major research question: How do I change the ehavior of children in preschool since 1989. The results were processed by the encoding.
