Use of rotational thromboelastometry (ROTEM) in perioperative medicine and its comparison with standard coagulation testing (PT, aPTT)
Jonáš, Jakub ; Durila, Miroslav (advisor) ; Vaněk, Tomáš (referee) ; Bláha, Jan (referee)
Assessment of the hemostasis is one of the basic components of patient care during the perioperative period. Coagulation tests, including prothrombin and activated partial thromboplastin time, fibrinogen concentration, and platelet count, are standard in hemostasis testing. However, the method of their evaluation and the time availability of their results are not satisfactory, especially in the case of the life-threatening bleeding. For this reason, rotational thromboelastometry (ROTEM) as a viscoelastic method appears to be more promising. The aim of the first part of this work was to verify whether the relevant ROTEM results are more available in time than the results of standard laboratory tests in conditions of our facility. The correlation of comparable ROTEM parameters and standard coagulation tests was evaluated in the second part of the work. Then, the impact of the hemostasis assessment using ROTEM on the reduction of transfusion products used before invasive and surgical procedures was evaluated. Finally, it was also determined whether the implementation of ROTEM in the management of the perioperative bleeding influences the blood loss, consumption of transfusion products and length of hospital stay. The results of this work confirm that the evaluation of hemostasis using ROTEM is significantly...
Students' successfulness and strategies when working with a map and factors affecting them
Havelková, Lenka ; Hanus, Martin (advisor) ; Knecht, Petr (referee) ; Bláha, Jan Daniel (referee)
Nowadays, information is increasingly presented in the form of various graphic materials. One of the key means of information visualisation is a map. Maps are complex representations and it is necessary to comprehend several cartographic concepts and to acquire skills and strategies for their efficient use. For this reason, it is important to give maps sufficient attention in the course of education. For the education to be of high quality, it is fundamental to understand the process of the map use and factors affecting this process and its successfulness. Therefore, the general purpose of the dissertation thesis is to develop this understanding. Specifically, the thesis has four main aims. One of them is to identify a map skill level of Czech students while using thematic maps since the popularity of thematic maps is increasing together with the number of cartographic insufficiencies they contain. These insufficiencies can inter alia cause a formation of misconceptions both about the maps and phenomena and regions they display. The second main aim is to identify and describe strategies that students choose to solve tasks which require the use of a thematic map. Additionally, the sub-aim is to understand the influence of chosen factors on the level of map skills as well as on choice and efficiency...
Adenomyosis and uterine fibroids: treatment and impact on fertility
Hlinecká, Kristýna ; Bláha, Jan (advisor) ; Pilka, Radovan (referee) ; Hudeček, Robert (referee)
Introduction In times of postponing the first pregnancy into the fourth or even fifth decade, there is a growing demand for fertility-saving procedures for these uterine diseases. As women age, fertility generally declines. The etiology of both diseases, as well as their relationship to infertility, remains uncertain. The prevalence of fibroids and adenomyosis is around 30 and 20 %. Treatment methods vary from pharmacological to surgical. In this study, we tried to compare two groups of patients with different types of fertility-sparing uterine surgeries and evaluate their reproductive outcomes. While myomectomy (the control group) can be considered a well-established procedure with standardized surgical steps and predictable fertility outcomes, resection of severe adenomyosis represents a newer and more controversial alternative to conservative therapy. Methods Patients of reproductive age with focal or diffuse adenomyosis who are planning pregnancy were included in the study. The diagnosis was performed ultrasonographically. Between 2004 and 2019, a total of 110 women underwent laparoscopic or open uterus-sparing surgery for clinically significant uterine adenomyosis (group A), diffuse adenomyosis (group AD), or fibroids (group B). Results Two groups of women who underwent different...
Choughs and irises. Anthropology of tourism, space and identity in Morocco
Konopíková, Michaela ; Soukup, Martin (advisor) ; Bláha, Jan Daniel (referee) ; Sokolíčková, Zdenka (referee)
The dissertation project is based on a long-term fieldwork among the Berber community in the Moroccan High Atlas Mountains. It looks at the transformation of the local environment since new discursive practices are emerging as a result of an interference of the global economy, environmentalism and developmental policies. Following Appadurai, the thesis raises a question of locality in contemporary world and neighborhoods, which are imagined, produced, and maintained against some sort of ground while the context-generative dimension of neighborhoods provides a theoretical angle on the relationship of global and local realities with the idea of culturally hybridized world. Together with Appadurai, the thesis deals with "what locality might mean in a situation where the nation-state faces particular sorts of transnational destabilization." The thesis has thus two main aims. (1) After describing the structural conditions in which the tourism industry in the mountains operates, (2) it will discuss the limitations of the locals' responses to the global market, or more broadly the impacts of globalization. It is necessary to establish a framework, which would connect the large- scale and small-scale processes and identify the concept of their dialectical relationships. Through such a reading, the thesis...
Non-traditional methods of drug administration in anesthesiology and emergency medicine
Kurzová, Alice ; Málek, Jiří (advisor) ; Bláha, Jan (referee) ; Gabrhelík, Tomáš (referee)
1 SUMMARY Introduction The thesis is focused on the research of efficacy and side effects of non-traditional, i.e. nasal administration of oxytocin and nasal and intramuscular administration of remifentanil. Nasal administration has the advantage of being non-invasive and useful in situations with difficult vein access (young children, extensive burns, terrorist attacks and battlefields). The dissertation has two parts that are closely related: nasal, intramuscular and conjunctival administration of remifentanil, nasal and intramuscular administration of oxytocin. Remifentanil is an ultra-short- acting opioid that is registered for intravenous administration only. Its main advantage over other opioids is its rapid metabolism after intravenous administration and absent accumulation even after prolonged infusion. Remifentanil is the only opioid for which, with the exception of two papers, intranasal administration has not been described yet; data on intramuscular and conjunctival administration are completely lacking. Oxytocin is a hormone that is used therapeutically primarily for its peripheral effects in the uterus and breast during pregnancy. However, other central effects have also been observed, i.e. anxiolytic effect, reduction of social stress levels and increase in empathy. It can be useful in...

BLÁHA, Jan
Bibliographical identification Title of the graduation thesis: Analysis of performance development in the Czech Republic in the course 3 000m steeplechase men from 1945 to the present Author's first name and surname: Bc. Jan Bláha Field of study: B7401 Physical Education Department: Department of Sports studies Supervisor: PhDr. Petr Bahenský, Ph.D. The year of presentation: 2022 Abstract: This diploma thesis deals with the analyses of performance development of Czechoslovakian runners on the course of 3000 meters steeplechase between years 1945 and 1992, and then Czech runners from 1993 until the present times (2021). The aim of this graduation thesis is to discover how the performance has evolved throughout the years and when we can observe its most significant increase. In the analytic part of the thesis the basic characteristics of 3000 meters steeplechase were described and examined with regards to the historic roots of this discipline, interpretation of valid rules, somatic and physiological preconditions of runners, stages of sports preparation, development of sports training and suitability and influence of high-altitude preparation within 3000 meters steeplechase training. The synthetic part contains charts and graphs that were obtained through data analysis from historic athletic charts and yearbooks.
The impact of the cartographic method on students' map skills level
Havelková, Lenka ; Hanus, Martin (advisor) ; Bláha, Jan Daniel (referee)
The presented diploma thesis focuses on the map skills' problematic, which is currently becoming widespread in the Czech research environment. In contrast to the previous empirical studies, this thesis is devoted to the thematic map skills and their level of development among students of grammar schools and geographically oriented branches of university studies. Due to the significant differences between used cartographic methods of visualization on thematic maps the main aim of this diploma thesis is to identify and explain used cartographic method's influence on the level of these important skills. To achieve this aim, it was necessary to focus on different parts of the curriculum (intended, implemented, learned) and to use several scientific methods because this topic hasn't been well established yet and therefore only few theoretical and empirical studies dealt with this specific issue. Firstly, the review of literature focused on thematic cartography, map skills and on identifying their level of development among students was done. Due to the lack of specialized resources the model of thematic map skills was created. This specific model was further used during didactic test's designing and also for its results' interpretation. Similarly for the creation of appropriate didactic test -...

Novotná, Kateřina ; Bláha, Jan Daniel (advisor) ; Hudeček, Tomáš (referee)
Use of mental maps of users in assessment of cartographic works Abstract The aim of this thesis is to propose and practical apply the alternative methodics of assessment of cartographic works. The thesis is processed in the terms of project of Grant Agency of the Charles University Mental Maps: subject and means for assessment. The adjoining aim of this study is then to test which of the assessed tourist maps is the most user friendly. As the method for data acquiring the questionnaire investigation methodology has been chosen. The basic for the assessment of cartographic works are in the case of this study of mental maps of lynch type. Theoretical part is devoted to Mental and Cognitive Maps as well as to the ways of cartographic works assessment. Space is also devoted to the methodology of assessment cartographic works itself. There has been defined the subject of assessment together with the statement of hypotheses and the aims of thesis. Practical application of the proposal methodology and assessment the results has been composed from several parts. First the tourist maps have been assessed by the expert himself. Afterwords another assessment has started with the use of mental maps. This assessment has been composed of the phase of preparation where the questionnaire itself was being created. Then it...
Cultural Aspects of Cartographic Creation: Use of Mental Maps in Cross-cultural Research
Bláha, Jan Daniel ; Soukup, Martin (advisor) ; Soukup, Václav (referee)
Cultural Aspects of Cartographic Creation: Use of Mental Maps in Cross-cultural Research Abstract: Diploma thesis deals with study of interdisciplinary issue of cultural aspects of cartographic creation. The first part of the work consists of theoretical introduction dealing with the map con- tent, map stylistics and map language, in which maps show the greatest cultural differences. The map figures here in a role of the image of reality and visual manifestation of culture. The analogy between a map and a classical language (linguistic anthropology) and the analogy between early maps and primitive cultures' maps are described. Beside the language, as determinants of the human spatial perception and other categories related to the map creation could be mentioned the environment, the experiences and the society, in which man lives. Several examples of so- called cultural map styles, especially from Australia and Oceania, are introduced as well. In the methodical part of the work in connection with cultural-anthropological research a method of cognitive maps, respectively mental maps of map users and map makers is discussed in detail. Just these maps are suitable to explore the cultural particularities of cartographic creation. The application part of the work presents the results of field research of mental...
