Analysis of ponies bred for sports performance based on results in international dressage competitions
Havlíčková, Kristina
This thesis aimed to evaluate the performance of sports ponies at the international dressage level based on the following factors: sports season, age, sex and breed. The basis of the database was the dressage pony ranking of the International Equestrian Federation from 2014 to 2020. Two analyses were performed, one for the whole population and the second for the top 10% of ponies of each season. Statistically significant impact was found in the sports season (p ≤ 0.05) and high statistical significance in age and breed (p ≤ 0.01). Sex was the only factor with no statistical significance (p > 0.05). Ponies achieved the best average results in the year 2019 (983.72 points). On average, the best age categories were 9-12 (968.91 points) and 13-16 (968.90 points). Stallions were the best-performing sex (975.28 points). Ponies of Dutch Riding Horse and Pony Studbook (1 040.70 points) and Danish Sports Pony (1 039.50 points) achieved the best point results. Only the sports season and breed in the top 10% of ponies showed statistical significance (p ≤ 0.05). Ponies earned the highest number of points on average in the year 2020 (1 873.80 points). The best performance was given by ponies aged 17 and higher (1 899.00 points), although this category contained only two specimens. Stallions earned the highest number of performance points (1 842.70 points), and the best breed was the German Riding Pony (1 828.20 points).

Influence of stress on women during pregnancy, childbirth and puerperium
HAVLÍČKOVÁ, Karolína
The subject of interest of this bachelor thesis is the impact of stress factors to women's health during pregnancy, childbirth and puerperium. The first aim of this bachelor thesis was to find out what is the most common stress cause for women during upmentioned periods. The second aim was to explore the women's ability to cope with stress. This thesis is divided into two parts - teoretical and practical. The theoretical part provides information about pregnancy characteristics (its duration, symptoms, signs and changes in the female body and organs during pregnancy). In subchapters related to pregnancy is the attention paid to prenatal diagnosis and stress factors during graviditas. The theoretical part also includes information about childbirth and its detailed periods. The subchapters considering childbirth provide summary of preparations for a delivery and the stress sources during the act itselves. The theoretical part also deals with the information about puerperium. This part is devided into subchapters which také into account breastfeeding difficulties, newborn care, stress factors affecting women in the puerperium, and psychological changes of women during puerperium. The final passage of the theoretical chapter discusses the definition of stress. The description of midwife role is possible to be found in each subchapter. The practical part of the bachelor's thesis founds its basis on a qualitative research in the form of individual semi-structured interviews. The survey was held from February to April 2021 and the group of analysed specimens consisted of 11 women not earlier than two months after they gave birth. To make the research anonymous the women were marked Ž1 - Ž11. All the interviews were held at the women's household with their approval. The research was going on in a covid-19 epidemic era, therefore all the restrictions such as face mask wearing and two meter distancing must have been kept during the visits. All the dialogues have been recorded, literally rewritten and analysed with women's assent. All the reached data have been treated by open coding, "pencil and paper" method (Švaříček et al., 2014). As the main categories for purpose of data evaluation have been marked: Pregnancy stress, birth stress, post-partum stress and their appropriate subcategories. The topics mentioned in "Pregnancy stress" are Covid-19 pandemic, partner's support, maternity clinic attendance and antenatal course. Aspects affecting the birth itselves are maternity hospital staff behaviour and partner's presence in the delivery room. The last category includes themes of breastfeeding and newborn care. On basis of the first, previously discussed, goal of this bachelor thesis was established the question which considers what is the most common stress cause during pregnancy, birth and six weeks post-partum. The result of this research indicates, that the women are most often stressed out because of the current coronavirus pandemic situation and prenatal diagnosis. The women are also worried about miscarriage or preterm birth. As the reasons of stress during the delivery were indicated hospital staff bad behaviour or a fear of being lonely and experiencing the feelings without partners. The investigation on the last category displays that over the post-partum period the women are worried about breastfeeding difficulties and insufficient childcare skills.The second question of the research followed up in what ways the stress impacts the women. From the survey it is possible to ascertain that all the involved women, except Ž1 were not affected by the stress in a long-term run. The specimen "Ž1" stated that her postnatal feelings and stresses had made her to shut herself off from her surroundings.The results of this bachelor thesis could be possibly used for scholar seminar purposes as a source of information for midwives. The other possible usage for this document would be a provision of needed information for pregnant women.

Degradation of polycaprolactone electrospun materials - methods of analysis
Havlíčková, K. ; Řezanka, M. ; Kobera, Libor ; Kuželová Košťáková, E. ; Lukáš, D. ; Jenčová, V.
Biodegradable electrospun materials are widely used for medical application. Polycaprolatone is polymer suitable for electrospinning technology and is very often used to create nanofibrous scaffolds for tissue engineering. The time to disintegration or biodegradation of such materials is very important here. However, testing is not entirely easy. It is not possible to create exactly body-like conditions in vitro. Moreover, it is not easy to find suitable analytical methods that would show exactly what happens in the nanofibrous polycaprolactone electrospun samples at certain stages of degradation, ie how the internal structure of decaying nanofibers changes. This paper describes the traditional use of methods for testing polycaprolatone nanofibers by enzymatically catalysed degradation. Morphological changes are studied using scanning electron microscope images. However, it also offers a non-traditional analysis of polycaprolactone electrospun materials using the ssNMR method.

Synthesis of ceramides with deuterated sphingosine
Havlíčková, Kateřina ; Vávrová, Kateřina (advisor) ; Hrabálek, Alexandr (referee)
Ceramides are a complex group of lipids belonging to sphingolipids. They are the most important component of stratum corneum (SC) and thus participate in a barrier function of the skin. In spite of the ceramides are a subject of intensive research, the exact effect of their structure to the barrier function of the skin is poorly understood. For studying the structure, properties and dynamics of SC lipid membranes, analogues of lipids labelled by deuterium are often used. The methods using deuterated molecules include neutron scattering, fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, deuterium nuclear magnetic resonance (2 H-NMR) and time of flight secondary ion mass spectrometry (ToF-SIMS). This work describes the synthesis of the ceramide with a deuterated sphingosine chain. The acquired ceramides with a different acyl chain length (deuterated as well as non-deuterated) should be used for studying their properties in SC lipid membranes in the future. The synthesis was based on methods commonly used for preparation of non-deuterated analogues of ceramides. The most important step of the synthesis was the incorporation of the deuterated chain into the molecule of sphingosine. The deuterated terminal alkyne was prepared from the perdeuterated bromoalkane. Next the deuterated...

Importance of Introduction of System Approach to Quality Control in Education
Havlíčková, Kamila ; Ortová, Hana (advisor) ; Trojan, Václav (referee)
The author of this Paper deals with the issue of the system approach to the quality control in education. In the contemporary market environment, school is an organization which should strive permanently for the improvement of its services. One of the possibilities is the establishment of the process of the permanent improvement through the application of some of the standardized models of the control and assessment of the quality. The Paper is aimed at the assessment of the contribution of the application of the CAF model for the self-evaluation and permanent improvement of the school. The Paper includes an assessment of a questionnaire survey, and a follow up analysis of the data obtained - to what extent the headmasters of schools know the standardized models (CAF, EFQM, ISO), or apply some of them in practice. The exploitability of the Final Bachelor Paper in the school practice: verification of the setting up of the vision and mission of the school, enhancement of the performance and the quality of work, preparing an action plan of improvement, self-evaluation of the school, benchmarking.
