Analysis of performance of embankment constructed on subsoil improved by vertical drains
Kováč, Vladimír ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The thesis deals with the back analysis of the instrumentated embankment on the subsoil, improved by prefabricated vertical drains. The first part is devoted to the theory of consolidation calculation. Furthermore, the author deals with a parametric study of the analytical calculation of prefabricated drains and the comparsion of the analytical and numerical solution. The last and the largest part of the work is a back analysis of the embankment which was built as a part of the subsoil improvement near the Suez Canal in Egypt by Keller GmbH.

Dewatering of foundation pit - numerical analysis
Krejzar, Vojtěch ; Boštík, Jiří (referee) ; Miča, Lumír (advisor)
The subject of the presented thesis is a foundation pit dewatering numerical analysis. The study is introduced with practical examples and the summary of the necessary theory. Individual subtasks are modeled as two or three-dimensional problem on a chosen foundation pit example. A comparison with analytical methods and theoretical knowledge about the problem is made. The studies focus on specifying the pumped water quantity, the shape of the depression curve, determining the size of the numerical model and the influence of the finite element network density. The steady-state flow cases, water table aquifer, a well system, sheet pile wall cutoff effect, surface drained pit and partial penetration cases are analyzed. The work proposes a method of modeling a well by FEM. The main output is a 3D analysis of a submerged excavation dewatered with a partially penetrated well system.

Úloha sestry v mobilizaci pacienta po operaci kýly
KRAMÁŘOVÁ, Iva
This bachelor thesis deals with the nurse´s role in mobilizing patients after hernia surgery. Post- surgery care partially consists of early mobilization of patients from their bed. Mobilization is movement, i.e. getting up from the bed, sitting up in a chair and walking practice. Early getting up after surgery helps increasing the venous circulation which prevents the development of a tromboembolic disease. Three objectives were set. Find out in what ways nurses mobilize their patients after hernia surgery. Find out what steps nurses follow when mobilizing patients after hernia surgery from the perspective of education and find out how patients perceive the nurse when taking care of them after hernia surgery. For the purpose of these objectives, four research questions were set. The thesis contains two research samples. The first research sample consisted of 6 nurses and the second research sample of 4 patients. The empirical part was implemented using qualitative research, interviewing method, the technique of standardized interview with nurses and patients on the surgical inpatient department. Interviews were transcribed word for word, analysed, and then coding was carried out. The method of ´pen and paper´ was chosen. The survey was run during March, April and May 2021. The results of interviews done with the nurses have proven that all of the interviewed nurses mobilize the patients after hernia surgery by getting up over their hip, however, they do not follow all other steps of correctly carried out mobilization. Nurses educate their patients orally, they use oral education right before the first getting up from bed. Some nurses, together with the oral education also clearly show their patients how to get up from bed. Further, it was found out that patients are being given sufficient amount of time by the nurses. The results of this bachelor thesis may serve as study material to students of medical subjects or nurses as inspiration for supplying high quality care of their patients. The survey results will be passed on to the workplace where the survey was carried out. Based on specific findings, the current educational methods may be updated including the means of improving after-surgery care for patients after hernia surgery. Thesis results are divided into individual categories. In Nurses´ survey, they are Mobilization, Education and Environment. In Patients´ survey, they are named as Communication, Mobilization, Nurse´s Surveillance when Getting Up from Bed and Nursing Care.

The Role of Imaging in Surgical Inflammatory Complications
KOPRDOVÁ, Eliška
The Role of Imaging in Surgical Inflammatory Complications Interventional radiology is a dynamic and fast developing specialization. Development of new methods and instruments extends possibilities of mini-invasive treatment of a wide range of illnesses. Introduction of a specific percutaneous drain in case of abdominal abscess in clinical practice counts among most important progress of 1980s concerning this field. The percutaneous drain is relatively fast and simple method and it belongs to urgent interventional operations. Indication for the percutaneous drain is a treatment or a palliative treatment of sepsis accompanied by an infected lesion. Most authors agree that there is no absolute contraindication of the percutaneous drain for pathological liquid collection. Therefore, this type of drain may be considered as a method selection. It is possible to execute it even before a possible surgical operation. The goal of my work was to assess retrospectively the experience of the Radiological Department of the Teaching Hospital in Plzeň Bory concerning this field within the selected period of time. For this reason, a single-purpose database has been created, which contains data of patients who underwent the percutaneous drain under the supervision of the CT or UZ within a certain period of time. Such data has been processed statistically. The work did not prove any of the hypotheses of mine that interventional techniques may in all cases substitute surgical operation while treating suppurative inflammatory lesions in the area of chest, abdomen and soft tissues. The percutaneous drain brings unquestionable advantages into clinical practice. Among most important ones, there are a removal of a surgical operation risk and of total anaesthesia, above all in the acute phase of illness. Simplification of post-operative care, shortening of the average hospitalization as well as economic advantages. This concerns a method that should always be considered as the first step among possible treatments of infected lesion.
