DETERMINANTS OF THE SHARING ECONOMY EMERGANCE; AN EXPERIMENTAL STUDY
Dahy, Adham Mohamed Wahied ; Miklánek, Tomáš (advisor) ; Prokop, Jaromír (referee)
This thesis explores the emergence of the newest type of economy the sharing economy one of the fastest growing economic phenomena in contemporary times. This thesis cites numerous research papers that encompass the sharing economy alongside other papers in different fields such as marketing and experimental economics. The main goal of this thesis is to disentangle possible channels that may have led to the increase in use of the sharing economy-provided services. To do so, we conducted an experiment using tools provided by the field of experimental economics. In the theoretical part of this thesis the main aim was to broadly explain what the sharing economy is as well as introduce the concepts to be used in the practical part. At the beginning I focus on defining the sharing-economy concept including its many definitions when it first appeared and the three phases that account for its emergence. I then explain the sharing economy concept providing the reason it is gaining worldwide recognition as well the main enablers behind it major companies involved with it the three main systems operating within it and the economics behind it. Finally I explain the many angles associated with its success, such as the concepts of Web 2.0 and P2P. Towards the end of the theoretical part I introduce the concepts that are relevant to the practical part and the experiment including risk-preferences information cascades and peerpressure. The practical part of this thesis focuses on the experiment including methodology designs treatments results etc. In the practical I present the hypothesis and the econometric model used for running the regression in order to test my hypothesis. Lastly I present the outputs I have obtained after running the regression, and comment on their significance and relevance to my hypothesis.

Health and social risks in children predisposed to metabolic syndrome
SLADKÁ, Alena
Metabolic syndrome was defined for the first time in 1988 by Reaven, who defined it as a hormonal-metabolic syndrome - with symptoms of resistance to insulin , hyperinzulinismus, hypertension and with laboratory-proven higher level of lipoproteid VLDL and lower level of HDL and LDL cholesterol. Obese children have big troubles concerning social relationships. Overweight children are often an object of ridicule, teasing, verbal bullying, physical bullying, cyberbullying and sexual abuse. First goal of this thesis is to find out, whether obesity (mainly of android type) in children and adolescents (aged 10-18) having BMI higher than 28 and waist size for boys over 103 and for girls over 93, overall cholesterol level over 6,5, blood pressure higher than 130/70 are predispositions of manifestation of MS in adulthood and to find out what are the social and health impacts of the obesity in the childhood. Second goal of this thesis is to find out, whether patients with metabolic syndrome (MS) had predispositions for obesity or were obese in the childhood and what are the health and social impacts of MS in their life. The first research group consisted of ten children aged 10-18 with predispositions to manifestation of MS. Methods of accomplishing goals of this thesis: Survey of health and family anamnesis. All ten children aged 10-18 were repeatedly checked during six mounths for their body weight, waist size, blood pressure and cholesterol. Surveyed values are shown in the table. I Used a structured interview to survey relationships of obese ones with same-age children, whether they are an object of ridicule and bullying and what are other troubles caused by the disease. At the same time I gave questionnaires to parents to ascertain the eating habits and life style of the family. Health and social impacts for life of people with diagnosed MS, when they were diagnosed MS and their childhood condition were examined using structured interviews in the metabolic advice centre. The research group consisted of ten patiensts of metabolic advice centre. After analysis of data and health anamnesis it was proven that 60% of researched children suffer from higher morbidity (breathing issues, upper respiratory tract infection, and easier fatigue during physical exertion). 60% of children have serious issues to establish relationships and suffer from verbal and physical bullying. 40% of adult patients of metabolic advice centre had troubles with obesity already in their childhood. All of them suffer from type 1 diabetes. Two of them recieve disability pension due to MS. 90% of them told, that they regulary go see a doctor und regulary take cures. These facts cause worse financial situation (lower income, expenses for cures and travel to a doctor). Two respondents mentioned discriminating behaviour of medical staff, however they didn't mention the type of discrimination. According to the questionaries only one person considers the MS is caused by his lifestyle. Research group consisted all the time of ten children and ten adults with MS, because 'Snowball sampling' research methods didn't survey any new facts, which would be needed to verify.

The Influence of Anatomical Structure of an Arm on the Results of Indirect Blood Pressure Measurement
Kreuter, Jakub ; Šrámek, Petr (advisor) ; Špunda, Miloslav (referee)
Important differences in the results of auscultatory and oscillometry blood pressure measurement in active and sedentary population led us to the idea of the influence of tissue, which is the brachial artery compressed across.On an artificial model we investigated possible influence of morphological structure of an arm on the accuracy of blood pressure measurement performed with indirect techniques. Results of the measurements testified, that the thicker stripe of the insulating material between the cuff and the tubing is, the higher pressure is needed to stop the liquid dripping. In order to be able to perform this experiment, we made an artificial model of an arm, consisted of glass paper-weight, infusion set and insulating material. Measurements were performed by an aneroid tonometer.We performed the studies on two groups of subjects - subjects in the first group were randomly chosen sportsmen, that took part on the regular port check-up.The health state of the persons was not allowed to influence the results of blood pressure measurements. In the first group, there were 48 subjects. The second group was composed of 10 subjects with big arm muscles and of 10 subjects with small arm muscles. All of the subjects in the second group were sportsmen, whose health state was not affecting the results of the...

Purification and characterization of selected human microsomal reductase
Skarka, Adam ; Wsól, Vladimír (advisor) ; Živná, Lucie (referee)
Area of human liver microsomal reductases hasn't been fully explored yet. Purification and characterization of still undescribed enzymes is an important step in finishing of this task. There is separation and purification of this reductases described in my work, with usage of hydrophobic interaction chromatography on low pressure chromatography instrument ÄKTA purifier. There were two columns with different substrates used, Phenyl sepharose (low sub) and Octyl sepharose. Separation conditions were the same in both cases. Results obtained by incubation of fractions and measurement on HPLC showed significant differences between both columns and their substrates. But it isn't possible to determine, which column is better for purification, because big area still remain for adjustment and optimization of purification conditions.

The value of neurohormonal activation assessment for treatment monitoring in congestive heart failure
Kubánek, Miloš ; Málek, Ivan (advisor) ; Špinarová, Lenka (referee) ; Pudil, Radek (referee)
Summary: Congestive heart failure (CHF) is associated with neurohormonal activation (NHA) which contributes to further progression of disease. Measurement of NHA has been used for diagnosis and prognostic stratification in CHF. Aims: The aim of this academic disertation was to analyze the value of NHA for treatment monitoring in CHF. We studied the relationship between NHA and pulmonary hypertension in compensated CHF using B-type natriuretic peptide (BNP) and big endothelin-1 (big ET-1). The rationale was to minimize repeated right heart catheterizations in candidates for orthotopic heart transplantation. A similar design had the second clinical study which used N-terminal pro-B- type natriuretic peptide (NT-proBNP) as a marker of NHA. In the third clinical study, we evaluated whether basal levels and/or change in NHA during treatment predict clinical efficacy of cardiac resynchronization therapy (CRT). We supposed that BNP and big ET-1 might be better predictors of outcome than standard methods of follow-up. Results: 1. Natriuretic peptides correlated with hemodynamic parameters better than big ET-1. An isolated measurement of BNP or NT-proBNP did not allow a reliable assessment of pulmonary hypertension or left ventricular filling pressure, respectively. On the other hand, serial evaluation of...

Study of laser mixture in the large pressure region
Morávek, Matěj Jan ; Hrachová, Věra (advisor) ; Kudrna, Pavel (referee)
This work studies discharge plasma in a mixture of gases, similar to that used in the so-called CO2-lasers. This mixture consists of CO2, N2 and He. The effect of the mixture composition and discharge parameters (especially pressure, in the range of 266 Pa - 100 kPa) on the distribution of energy in the vibrational levels of nitrogen was examined. This is important parameter for modelling of the discharge plasma. The effect of the mixture composition on the degree of dissociation of the CO2 molecules was also studied. The relative concentration of CO was applied to find the conditions leading to a minimal dissociation of the carbon dioxide. Measurements of radial profiles were also made. Results from two discharge tubes made from different materials were compared. Two types of discharge were utilized to acquire a wide pressure range - low pressure DC glow discharge in the range of 266 Pa to 1330 Pa and dielectric barrier discharge in the range of 5 kPa to 100 kPa. Both discharges are used in commercial CO2-lasers. We observed a descending dependence of the vibrational temperature on the pressure and a big step caused by increased occurrence of standing ionizing waves in the mixtures with low nitrogen ratio. Vibrational temperature in the DBD was markedly lower than in the DC GD, because of the...

Comparison of Non-invasive Blood Pressure Measurement Methods
Skořepa, Michal ; Fabián, Vratislav (advisor) ; Špunda, Miloslav (referee)
The aim of this diploma thesis is to compare and evaluate the results of two most widespread blood pressure measurement methods. First method, which is used as reference in this work, is auscultatory method. Nowadays, it is most often used method and it is based on auscultatory sounds. The sounds were described by the Russian physician Nikolaj Korotkov in 1905. The auscultatory method uses a tonometer with inflatable cuff and a stethoscope. The cuff is wrapped around an upper arm or wrist and inflated to about 30 mmHg above the systolic pressure - the pressure at which the radial pulse is obliterated. With the stethoscope placed over the brachial artery distal to the cuff, the cuff is then deflated at a rate 2 to 3 mmHg per second or heart beat, during which Korotkoff sounds can be heard. The cuff pressure at the onset of Korotkoff sounds, or tapping sounds, is generally taken to be systolic pressure. Diastolic pressure is generally taken to be the cuff pressure at the onset of silence. Second method used is oscillometric method. This method is based on evaluation of oscillometric pulsations that are generated in cuff during increasing or decreasing of the cuff pressure. The big problem of this method is the no clear criterion for evaluation of systolic and diastolic pressure. BPs are usually determined by...

The Patients´ Intimacy Problem during the Preoperating Preparation and the Transport to the Operating theatre on the Orthopaedic clinic.
FERENCZOVÁ, Romana
The bachelor thesis is specialized in the intimacy of the patients during pre-operative preparations and movement to the operating theatre in the orthopedic department. The thesis is also specialized in the nurses?s behavior which these activities are doing. The intimacy is still discussed topic. It is the conflict of the right of patient to privacy and the effort of medical staff members to the best pre-operative preparations and subsequent movement on the operating theatre. In spite of the big efforts of medical staff members there are the situations which cause the shyness and the shame of patients. The main reason is time pressure which is exerts on the medical staff members. The disruption of the intimacy can be caused by the wrong communication between the nurse and the patient but also between the staff themselves. Every patient is individuality and therefore there is not possible to set one standard working procedure which solves this situation. The main objective of this thesis was to find out how the intimacy of patients during pre-operative preparation is secured and to study possibilities of the ensuring intimacy during movement to the operating theatre. The next objective was to find out during which activities (performances) during pre-operative preparations the intimacy used to be frequently devastated. The data were obtained within qualitative research from two non-standard interviews. One type of interview was done with seven randomly chosen patients of the orthopedic department. The second one was done with seven nurses working in the medical facility. One of the nurses is working in the operating theatre. The nurses from the inpatient ward were asked if they respect the patient´s intimacy consistently than the nurses in the operating theatre. They were also asked if there is difference in observance of patient´s intimacy during pre-operative preparations in the scheduled operating performance and urgent performance. The objectives of the bachelor thesis were fulfilled. During interviews there was found out that the disruption of the intimacy was most often realized during movement to the operating theatre. The identified results will be provided to the management of the medical facility to create the standard for the securing of the patients intimacy on the operating theatre.

Dance and it´s influence on mental and physical health of adolescents.
BLAŽKOVÁ, Klára
Bachelor thesis examines the impact of dance on adolescents. The goal of this work was a realization of dancing intervention program and verifying its psychological and physical effect on the selected group. This research involved 25 senior students from High School and Business College Marianske Lazne. Before the start of the program, students were tested using the Iowa-Brace tests, test of balance on beam, Jacík´s motoric tests, Poms questionnaire and the test of coloring characters. In addition, their blood pressure was measured and an author-made questionnaire was given them for filling in. The intervention program was carried out for four months and culminated with a public performance as a dance show in their prom. After completion of the intervention program students underwent the same tests as before, with the exception of the questionnaire. The evaluation of the results showed that there was an improvement in all the tests and thus the research assumptions were confirmed.
