Care for a patient intoxicated by mushrooms - preparation of simulation scenarios
KOHOUTOVÁ, Denisa
The thesis focuses on patients mushroom poisoning and preparation of simulated scenarios. The thesis is mainly theoretical with addition of two simulated scenarios, which are supported by specialised literature, magazines and Czech or foreign websites. Firstly, intoxications in general overview, symptoms, first aid and treatment are studied. In the next chapters complete overview and description of mushrooms is given, without it the thesis would be incomplete. Lastly, mushroom intoxication, its symptoms, pre-hospital care, treatment and hospital care are described. Mushroom intoxication is immediate life threatening condition, if it is not treated correctly and in time. Suicide and accident can be reasons for this type of intoxication. Early diagnoses of the toxic substance in the mushroom and early treatment are used to treat even the harshest of cases. Most common, however less serious, intoxications are caused by panther cap, this type of mushroom is easily mistaken for blusher. As the most dangerous mushrooms intoxication is considered the one caused by death angel. Death angel consists of high number of toxins and is often mistaken for blusher or champignon. The death doses of this mushroom is estimated to only few tenths of a gram - in other words to one mushroom or less. Consumption of poisonous mushroom mostly affects liver and kidneys. Blood chemistry test, urine test and test of the gastric content are important parts of diagnosing mushroom intoxication. Important step of removing and eliminating toxins from patient's body is invoked vomiting and gastric lavage with administration of bituminous coal. Hospital care provided by nurse is significant part of intoxication treatment. Nurses take care of airways, they monitor basic vital functions, assist during invasive procedure, collect blood samples based on doctor's ordination and they provide hygienic care and decubitus prevention. Diploma thesis can be provided as a textbook material for nurses and paramedics. Mostly in regard to simulated scenarios.

Virtual reality in psychology and psychotherapy
KAFKA, Dominik
The bachelor thesis deals with the use of virtual reality in psychology and psychotherapy. The design of an overview study was applied and different databases about the current theme were used. It first introduces to the general reader information about virtual reality, its purpose, and aspects. Then follows the chapter on virtual reality in psychology, in which the thesis deals with the advantages and disadvantages of virtual exposure as well as with current psychological research, such as spatial perception or virtual learning environment. The last thematic area is virtual reality and treatment, which is devoted to the treatment of phobias, treatment of post-traumatic stress disorder, substance abuse, pain, obesity and other difficulties for which the effectiveness of the use of virtual exposure was determined. The special emphasis is placed on description of the selected virtual reality applications for the possibility of creating a better idea of the course of its exposure. The following discussion summarizes the findings of the utilize reasearch and also the effectiveness of the use of virtual reality in individual areas of therapy is derived. Current recommendations and potential attributed to individual possibillities of using virtual reality in psychology and psychotherapy are also presented here. The main search keywords include: virtual reality, VR, VRET, psychology, psychotherapy, immersion, therapy, exposure, simulation, and specific keywords needed to complete the content of the sub-chapters.

Comparison and evaluation of mathematical methods in proceedings
ŽÁKOVÁ, Jana
In the preamble of the report, there are briefly described the basic notions of network analysis (the project and the network graph). Special attention is applied to the deterministic methods (Critical Path Method, Metra Potential Method) and their calculation as well as stochastic method (Program Evaluation and Review Technique, Graphical Evaluation and Review Technique), which are narrowly analyzed in the next chapter of the final report. The last two chapters of this part of the report are focused on the possibilities of simulation at proceedings projects and the software as a fundamental asset for planning and proceedings projects. The second part, which is mainly oriented to the practical points of problem, proposes the answer to stochastic and deterministic project at the application of the simulation technique by means of selected software.

Application of pedestrian evacuation and fire spreading models for specific buildings safety improvement
Okřinová, Petra ; Hromada, Martin (referee) ; Dvořák, Zdeněk (referee) ; Apeltauer, Tomáš (advisor)
The current trend in the construction industry is construction “without limits”. In projects and implementations, we encounter non-traditional combinations of operational solutions, geometry and materials, which are still approached mainly using the classic standards from the fire safety point of view. The latter does not allow to comprehensively cover all aspects of these specific buildings without a greater degree of subjective simplification. This raises the question of whether, even in these cases, it is still appropriate and safe to use only a standards approach, or whether buildings deviating from traditional construction should be assessed differently – for example, by so-called fire analysis using numerical models. Currently, users still have very little information about the use of these models, and even in the Czech legislation, there is no document recommending how to proceed when using them for the purposes of building fire safety solutions. Numerical models of evacuation and fire analysis are thus currently the most effective tool for impact analysis and preliminary verification of the effectiveness of proposed safety measures. Therefore, it is necessary to deal with their validation and use, with the goal of innovating existing approaches and standardizing numerical models for fire safety assessment of buildings. Furthermore, it is necessary to compare their possibilities and limitations concerning ČSN and to put together a comprehensive information background as a basis for their more active implementation in practice. The presented work thus focuses on the above-mentioned issue and demonstrates its use of application examples of real specific buildings and a set of compiled studies. The work also points out specific shortcomings and simplifications of standard approach methods, based on which verified procedures and recommendations for the incorporation and use of numerical models in fire safety practice are then established.

On a class of biped underactuated robot models with upper body: Sensitivity analysis of the walking performance
Papáček, Štěpán ; Polach, P. ; Prokýšek, R. ; Anderle, Milan
Biped underactuated robots with an upper body (being a torso) form a subclass of legged robots. This study deals with the walking performance of such class of legged robot models and has been motivated by the need to implement of the previously developed sensor and control algorithms for the real-time movement of the laboratory walking robot, designed and built at the Department of Control Theory of the Institute of Information Theory and Automation (UTIA) of the Czech Academy of Sciences, see Fig. 1 (left). A detailed description of this underactuated walking-like mechanical system (called further UTIA Walking Robot – UWR) is provided in [2] and [5]. The simplest underactuated walking robot hypothetically able to walk is the so-called Compass gait biped walker, alternatively called the Acrobot, see Fig. 1 (right). For a review of underactuated mechanical systems, i.e. systems with fewer actuators than degrees of freedom, which encounter many applications in different fields (e.g., in robotics, in aeronautical and spatial systems, in marine and underwater systems, and in-flexible and mobile systems), see [3]. As follows, we examine the walking performance of parametrized models for different walking regimes and different values of model parameters. More specifically, the sensitivity analysis (i.e., parameter study) of the walking performance with respect to certain design variables (model parameters) is carried out using the software package alaska/MultibodyDynamics. The main attention is attracted to the role of the upper body mass m3 and position lc3, see Fig. 1 (right). Last but not least, having surveyed the mechanics of planar biped robots, our subsequent goal is the analysis of a 3D biped model where lateral balance is either controlled, suppressed or compensated.
