Developing open approach to mathematics in future primary school teachers
Samková, L. ; Tichá, Marie
In our contribution we focus on the possibility to develop open approach to mathematics in future primary school teachers during a university course on mathematics conducted in inquiry-based manner. We analyse data obtained in the beginning and in the end of the course with respect to two main aspects related to open approach to mathematics: searching for all solutions of a task, and acceptance of different forms of notation of a given solution. Data analysis revealed in the participants three different shifts towards open approach to mathematics, and showed that after the active participation in the course each of the participants improved at least in one of the monitored aspects, and that none of the participants got worse in any of the aspects.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.

Nové postupy biomonitoringu cizorodých látek ve vodním prostředí
ČERVENÝ, Daniel
Within the presented work, several approaches of biomonitoring were studied. A well-established method for human health risk assessment was applied to evaluate the quality of fish from open waters in the Czech Republic. As this work is targeted on sport fishermen, who frequently consume their own catches, besides the publication in scientific journal, a brochure with results of this study was distributed via the Czech Fishing Union. Health risks for consumers related to the consumption of wild fish were found strongly species and locality dependent. As there is no risks related with the consumption of carp (Cyprinus carpio) at all investigated sites, frequent consumption of predatory fish should be avoided at some fishing grounds. The use of passive samplers has become more and more attractive in the last two decades. As these devices are able to mimic the biological uptake of chemicals, their potential for replacing fish as bioindicators in routine biomonitoring programmes is evident. In our study, the comparison between analysis of fish tissues and POCIS extracts from selected sampling sites confirms this idea about interchangeability of these indicators in the case of PFASs as target pollutants. Moreover, no metabolic transformation of contaminants present in water take place in passive samplers contrary to living organisms, thus these reflect the actual contamination at the locality more precisely. The use of passive samplers completely fulfils the internationally accepted principles of Replacement, Reduction, Refinement (the three R´s). Another promising approach using YOY fish as bioindicators was evaluated within the present study. Multispecies samples of YOY fish homogenate was found as a better indicator for wide range of pollutants than muscle tissue of adult fish within one species from the same locality. As all inner organs and tissues are presented in analysed samples, more target pollutants in higher concentrations are detected compared to the muscle of adults. Besides the higher sensitivity in pollutants detection and quantification, practical and economic benefits are of concern in the case of the YOY fish approach. The YOY fish approach also particularly fulfil the three R´s strategy, as sampling of this age group of fish has a smaller impact on the environment than the sampling of adults. In case of mercury, that was found as a limiting contaminant for the consumption of fish from open waters in the Czech Republic, a nonlethal method of finclips sampling can be used for the monitoring of this compound in aquatic environments. Besides the monitoring, our optimised method for the estimation of muscle tissue concentrations could be used for human health risk assessment as well. The difference between real muscle concentrations and concentrations estimated using our method differs less than 10% in most of the investigated localities. Benthic organisms are an important part of the food web in aquatic environments, but insufficient information about its contamination is available. In another study included in this thesis, first evidence about bioaccumulation of certain pharmaceuticals in benthic organisms was described. Although, pharmaceuticals are generally considered to be not accumulative in organisms, our study proved that certain pharmaceuticals have bioaccumulation potential. From this finding, it is evident that not only the concentrations of pharmaceutical dissolved in water but also the diet represents an important exposure pathway of contamination by these compounds for organisms (fish) inhabiting aquatic environments.

Changes of the attitude of a nurse towards the nursing care after his/her ranging to a higher position.
PROCHÁZKOVÁ, Marie
The Thesis deals with a change of an approach of a nurse to nursing care provision after her promotion to a managerial position. A nurse appointed to the position of charge or head nurse has different responsibilities, she becomes a manager, her colleagues have suddenly become her subordinates, whose work she has to organize, lead and control. A wide range of new responsibilities might change her approach to provision of nursing care. The aim of the Thesis was to discover whether and how the approach of a nurse to nursing care changes when she is appointed to a managerial position and how a nurse promoted to a managerial position achieves authority among her subordinates. The following hypotheses were chosen in relation to the aims of the Thesis. Hypothesis 1: The approach of a nurse to nursing care changes after being promoted to a managerial position. Hypothesis 2: A nurse promoted to a managerial position requires provision of nursing care in line with nursing standards. Hypothesis 3: A nurse promoted to a managerial position is responsible for nursing care quality. Further research questions were put: 1. Is it difficult for a nurse promoted to a managerial position to achieve authority among senior nurses? 2. Is it difficult for a nurse promoted to a managerial position to control nursing care provided by shift nurses? 3. Is it easier for a nurse promoted to a managerial position to organize work for shift nurses she did not work with before? Quantitative research in the form of questionnaires was applied to confirmation or refutation of the hypotheses. The research sample consisted of head and charge nurses from South Bohemian hospitals and from hospitals in Příbram and Pelhřimov. Qualitative research was organized in the form of unstructured interviews with head nurses from Hospital České Budějovice. After evaluation of the results all the three hypotheses showed confirmed. The research results confirm that an approach of a nurse changes after their promotion to a managerial position. They are much more responsible for quality work among her subordinates. The results of the work will be presented at all-house seminars and conferences and published in a specialized journal. The results will also be provided to the hospital management {--} to the Nursing Care Manager {--} and finally to the respondents involved in the research.

Cardiac Surgical Patient in the RES Room and the Approach of a Nurse to Nursing Care
KAFKOVÁ, Zuzana
In the past years, the cardiac surgery performance was very demanding. The limited range of medical performances, imperfect procedures and techniques resulted in frequent postoperative complications and high postoperative mortality. Over time, surgical techniques, heart replacements, extracorporeal circulation and postoperative care have improved. This makes it possible today to operate on much older patients, where surgeries previously were nor feasible. The diploma thesis on the topic Cardiac surgical patient in the RES room and the approach of a nurse to nursing care is dedicated to the patient after heart surgery. It deals with meeting the patient's needs in the RES room and what the patient perceives while staying in the resuscitation unit and what he /she needs from a nurse. In the empirical part of this thesis two objectives were stated. To determine what a cardiac surgical patient perceives and what he /she needs in the RES room, and to find out whether it is possible to improve the quality of patient-oriented care. Based on these objectives, hypotheses and research questions were established. The objectives were successfully achieved, the hypothesis was confirmed and the questions answered. The research was conducted using qualitative quantitative research methods in the RES units of the cardiac surgery department, where the patients with heart disease are operated on. For the quantitative research the questionnaire interview method was selected. The qualitative research method was used to carry out semi-conducted interviews with the patients.
