Urolithiasis as a biosocial problem of man
Černá, Helena ; Přívratský, Vladimír (advisor) ; Pavlasová, Lenka (referee)
Bachelor thesis Urolithiasis and the influence of dietary habits on human society aims to find out everything about the disease, called urolithiasis. It occurs in humans, but can occur even in animals. Therefore, it is conceived as a natural and medical aspects are not decisive. Urolithiasis affects the urinary tract and renal parenchyma mainly, because the work is in the theoretical part focused first on the general exclusion, which in this work are inherent. It also deals with urolithiasis, since its first references in the literature to the present. How and why it arises, its prevention, causes and etiopathogenetic factors affecting incidence. It occurs in all age groups, without exception, human races and on all continents. In the final phase of the work addresses the investigation, whose aim is to find out what sex is more susceptible to the disease, which age group is more at risk, which increases the risk of job creation and last, the survey focused on respondents and their eating habits. Proper diet, which is meant compliance with dietary habits, insufficient fluid intake and avoidance of different stress conditions is one of the most important factors that have a positive impact on the incidence of urolithiasis.

Comparison of hip joint offset in resurfacing arthroplasty and standard total hip arthroplasty
ČERNÁ, Helena
Comparison of hip joint offset in resurfacing arthroplasty and standard total hip arthroplasty. Summary The subject of this work is to compare a hip joint biomechanical parameters after two different operations, after a standard total hip arthroplasty and after hip surface replacement. Material and method: A group of twenty five patients with a hip surface replacement has been processed in a statistical way, their average age was 55 years (from 34 to 66 years), next a group of thirty patients with a standard total hip arthroplasty and the average age was 62 years in this group (from 46 to 72 years). Anteroposterior radiographs of the pelvis with inside rotation about 15{$\rm^o$} was taken of all patients. The measured biomechanical parameters were femoral offset and femoral length, cup offset and cup height. For statistical processing the total offset was defined as a sum of the femoral offset and cup offset, hip length was defined as femoral length minus cup height. Postoperative measured data of an operated hip joint were compared with preoperative data. Statistical analysis has been done by a paired t-test. Results: The patients, who underwent an operation of hip surface replacement, were in average by 7.8 years younger than the patients with a standard total hip arthroplasty. Men predominated in the group with surface replacement and women predominated in the group with a standard total hip arthroplasty. Preoperative measured data were approximately identical in both groups. In the group with a surface replacement the postoperative total offset has increased in average by 0.04 cm (p=0.79) and hip length has decreased in average by 0.41 cm (p=0.0001). The postoperative total offset has decreased in average by 0.83 cm (p=5x10-5) in the group with a standard total hip arthroplasty and the postoperative hip length has decreased in average by 1.49 cm (p=6.17x10-5). Conclusion: On the basis of taken paired t-tests the hypothesis can be substantiated that a surface replacement restores hip joint physiological conditions better than a standard total hip arthroplasty.
Selected Aspects of the Use of Documentary Credits in International Trade
Nejedlý, Michal ; Černohlávková, Eva (advisor) ; Černá, Helena (referee)
This diploma thesis deals in detail with the matter of amendments to documentary credits. The amendments are analysed in terms of their causes, subjects that may initiate their execution, and their process itself. Also analysis of respective articles of interpretation rules UCP 600 relating to credit's amendments is included. Prior to the above mentioned analysis of amendments there is a part regarding the term of documentary credit, its process, regulation and contemporary position in international trade. In the connection with credit amendments the attention is given to the techniques of their execution, namely through the SWIFT system. The subject of the last part of the thesis is the quantitative analysis of credit amendments on the example of the analysis of real transactions which are assessed from various points of view. Statistical analyses are carried out aiming at considering of the existence of the relation between the region of the credit applicant and the number of credit amendments and between the credit amount and the number of amendments.
