Factors influencing the satisfaction of patients with provided nursing care
MORONGOVÁ, Adéla
Current state: The satisfaction of patients is an important factor for the quality of nursing care. Nursing care should be mainly focused on meeting the needs of patients and many other factors. This greatly affects the patient's subjective feeling of satisfaction or dissatisfaction with either the proper nursing care, or other factors. The patient is an active participant in the treatment, not a passive recipient of nursing care. Measuring the satisfaction of patients is one of the requirements for the accreditation of hospitals. Research objective: The aim of the research was to determine the satisfaction of patients with the provided nursing care. Another objective was to demonstrate a statistically significant relationship between the satisfaction with nursing care and the impact factors: sex, age, education, environment and the routine on a standard ward, communication with patients and nurses attitude of nurses to patients. Methodology: The research was realized using quantitative methods. For my research I used a standardized questionnaire called Quality seen by patients - evaluation of inpatient care, which included 34 questions. The questionnaire for the assessment of patient satisfaction was compiled into several areas: satisfaction of patients with the hospital stay, with the nursing care provided, with leaving the hospital, with the general assessment of the health care provider. The survey covered the period from January to March 2015 at the standard surgery and internal medicine department in the hospitals of České Budějovice and Český Krumlov. For the survey I selected the patients who were hospitalized in these departments for at least 3 days. The data obtained by a quantitative research were later tested by SPSS software. For statistical testing we selected the chi-square and the tick chart. The significance level was set at 5%. Participants: As part of the survey, a total of 200 patients were approached. 100 patients were interviewed in the hospital of České Budějovice in surgery and internal medicine departments. The remaining 100 questionnaires were distributed to patients in the hospital of Český Krumlov, again on the internal and surgical wards. The total return of the questionnaires was 100% (200). Results: The research shows that men are less satisfied with the received care than women. An important factor in patient satisfaction showed to be the education of the respondents. University-educated patients were significantly less satisfied with nursing care than respondents with secondary and primary education. Another examined factor was the sleep schedule. Approximately one fifth of the surveyed patients (22%) stated that noise caused by other patients was disturbing. The respondents who indicated that were disturbed by the noise in the department, rated the satisfaction with nursing care significantly worse. Conversely, the patients expressed satisfaction with the wake-up time. In the area of the patient satisfaction with the cleanliness of the rooms and toilets, the research survey showed that satisfaction decreases significantly if the patients are not satisfied with the cleanliness of the toilets and rooms. The environment, in which the patients are hospitalized, greatly influences their satisfaction with nursing care. Another important factor for the patient satisfaction is also the communication and the attitude of the nurses to them. If the attitude of the nurses is compassionate, soothing and they pass information to the patients in an understandable way, the patients have more confidence and are more satisfied. This is true when the patients meet their needs and feel that they are treated with dignity and respect. Conclusion: The research shows that these factors affect the satisfaction of patients with nursing care and in the context of these results the importance of highly individualized care is increasing. Nurses must significantly contribute to improving patient satisfaction.

Zjednodušení kvantových obvodů pro modulární umocňování
Fišer, Petr ; Ivánek, Jiří (advisor) ; Nentvich, Libor (referee)
This thesis is based on top of the previous thesis "Security of modern encryption protocols" where we introduced a new paradigm for constructing quantum circuits. We have built circuits for modular arithmetic (addition, multiplication and exponentiation) in order to break El-Gamal asymmetric cryptosystem. Current thesis reviews all proposed circuits and discusses possibilities of their further optimization in goal of lowering the number of used qbits at least by an order of magnitude. It also shows that this is not possible due to existence of COPY gates which make the design inherently unoptimizable. Getting rid of COPY gates is, however, not possible without substantial rewrite of the whole paradigm. The overall estimate of number of qbits used in circuits thus remains O(log(m)log^2(N)) where m is a processed number and N is a modulus. The thesis also proposes optimization of the modular multiplication circuit that, if issues with COPY gates are resolved, allows us to lower the number of used qbits by about O(log(m)) at the price of a longer execution time.

The current state and prospects for sustainable development of tourism in Slovakia.
Libantová, Silvia ; Indrová, Jarmila (advisor) ; Chaloupka, Radek (referee)
Tourism contributes to the prosperity of destinations by bringing financial resources, new jobs, a higher level of services and infrastructure development. However, if tourism does not develop sustainably, it is accompanied by negative factors, as well. Especially, negative impacts on the environment, such as: water and soil contamination, increased noise and overcrowded destination during the high season. As a response to the worsening state of the environment and possible irreversible changes caused by irresponsible human behavior, the idea of sustainable development is becoming more important. The theoretical part describes tourism in the Slovak Republic and highlights plans for sustainable tourism development. In the practical part, the results of the questionnaire, related to the awareness of sustainable tourism in the Slovak Republic, are evaluated. The main objective of this thesis is to evaluate the current situation in the field of sustainable tourism and to make suggestions for its future development.

Noise Analysis of Ion Transfer Kinetics at the Micro Liquid/Liquid Interface
Josypčuk, Oksana ; Holub, Karel ; Mareček, Vladimír
Fluctuation analysis was utilized to determine the TEA ion transfer kinetics across the water/1,2-dichloroethane interface. The average value ks = 0.34 cm s-1 is comparable with the previously reported value ks = 0.2 cm s-1, derived from electrochemical impedance spectroscopy experiments. The experimental approach utilizing a thick wall glass microcapillary to fix the interface exhibits a very small stray capacitance value, proving this system to be suitable for determining the kinetics of the fast ion transfer across a liquid/ liquid interface. Application of a method employing a small perturbation signal prevents polarization of the inner capillary surface by current flowing through the cell. The induced polarization of the capillary can affect ion concentration at the interface due to electroosmosis and thus make the kinetics data evaluation difficult or erroneous.

High-order frequency filters using modern active elements
Chrást, Jakub ; Minarčík, Martin (referee) ; Jeřábek, Jan (advisor)
The bachelor thesis deals with the designing of active frequency filters of the second – order which is useful for the construction of cascade high – order filters. These filters were designed by means of autonomous circuits. Multiple current mirror and inverter MCMI, current operational amplifier COA and current differencing transconductance amplifier CDTA were used as active elements. Designing is focused on the circuits using MCMI. Designed filters work in current mode. In the introductory part there are described general characters of frequency filters. The second part includes the methods of construction high – order filters, the third part contains the description of active elements used. The design we can find in the fourth part. The functionality of filters was verified by computer simulation. One of the optimal filters was practically verified by available component UCC 0520. Two other filters were used for the construction of the fourth – order filter.

Horyna, Roman ; Finková, Dana (advisor) ; Gnad, Tomáš (referee)
Title of the thesis: Current concepts of double poling by classic technique in cross-country skiing Object of the thesis: The spatial-temporal analysis of node points and kinetic phases of the kick double poling and double poling of selected competitors at the FIS Nordic World Ski Championships in Liberec 2009. Method: A case study in which we used the kinematographic method for the analysis of the kick double poling and double poling of selected competitors. We analyzed the video of the 15-km classic in the FIS Nordic World Ski Championships in Liberec 2009. For the analysis we used the software APAS. Results: We performed spatial-temporal description of node points and kinetic phases of the kick double poling and double poling of selected competitors. We characterized current concepts of kick double poling technique, because selected competitors were relatively homogeneous set. By double poling we found out flexion-extension pattern in elbow, hip joints of slipping lower limb and partly in knee and ankle joints of slipping lower limb which results in generation of great propulsive force. Double poling becomes more significant driving element than push-off. Keywords: cross-country skiing, kick double poling, double poling, kinematic analysis, top competitors
