Prospective study of adults diet and their vitamin D blood level
HAVLOVÁ, Adéla
Vitamin D is a widely discussed topic in domestic and foreign literature. Vitamin D serves many functions in human body, for example in affects calcium metabolism. Vitamin D is produced photochemically during sun exposure and partly it is consumed with food intake. This thesis is concerned with the problematic of dietary intake of vitamin D. The goal of my research was to analyze a relationship between a specific amount of vitamin D intake with food and vitamin D level in blood in a person. In this research quantitative methodology - prospective method was used. The participants of my research wrote down every meal they ate every day for nine months. They specified amount and kind of consumed food intake. Participants blood was analyzed for levels of calcidiol, alkaline phosphatase, calcaemia and phosphataemia. The blood was taken twice during the research. The number of participants involved six women and three men. The research started on 1 March 2021 and lasted until 30 November 2021. The participants from the research had no record of gastrointestinal diseases, this could affect vitamin D absorption from dietary intake and that could lead to biased results. This research was led as a blinded experiment to prevent experimental bias. It was important that the participants did not consume higher or lower amounts of vitamin D on purpose. Each participant followed regular assorted diet and did not restrict oneself in food intake. The results showed that participants of this study consumed more vitamin D in their diet on weekends rather that in a regular day. It was further discovered that in spring vitamin D blood level correlated with the amount of consumed vitamin D in diet. Median value of vitamin D intake in diet for one participant was 2,268 g per day, average value was 3,55 g per day. Based on the evaluated participants lists of meals was discovered that the amount of consumed vitamin D in diet made 17,75 % of its guideline daily amounts.

Handwriting in a healthy adult population.
Mikolajková, Marie ; Krivošíková, Mária (advisor) ; Gerlichová, Markéta (referee)
Handwriting is part of the graphomotor skills necessary for functional communication in everyone's life. The field of adult handwriting is not sufficiently developed in the Czech Republic yet. This thesis focuses on handwriting in a healthy adult population. The main aim is to describe adult handwriting, individual parameters of writing, factors influencing writing and to present the current possibilities of handwriting assessment. The theoretical work also discusses the benefits of handwriting, the benefits and negative consequences of modern technology on handwriting performance. The aim of the practical part is to describe the differences in the level of handwriting between younger (age 20-29) and older (70+) adults and thus to contribute to the development of standards for the Czech version of the Handwtiting Assessment Battery for Adults (HAB) in healthy adult population. The data were collected using the HAB instrument in the sample of 141 individuals. It is quantitative type of work. The data collection was based on stratified random sampling, the data were statistically processed and subsequently tested against the established hypotheses. The sample was stratified by age and gender. Increasing age of probands can be considered to be the most significant factor affecting handwriting...

Methods of measurement of intelligence in adult subjects
Chvátalová, Veronika ; Flegr, Jaroslav (advisor) ; Lindová, Jitka (referee)
In my work I focus on intelligence testing in adult subjects. The work aims to introduce to the readers six intelligence tests that might be administered both individually and in a group. Besides intelligence tests measuring complex intelligence abilities I would like to mention also a partial test measuring nonverbal abilities. Characteristics, structure and description of tasks will be specified for each test as well as psychometric properties and usage. Advantages and disadvantages of each test will be evaluated in the end. Where possible, I present also the usage of each test in the Czech Republic or in Europe.
