Meeting needs a higher level in patients with injury at acute care beds
ROUBÍČKOVÁ, Radka
Human need is a manifestation of a certain deficiency the removal of which is desirable. An injury disrupts the usual way of a person´s life, changing daily routines and reducing regular activities. A nurse working in the department where patients with injuries are hospitalized should have sufficient knowledge on the subject, must show patients her understanding and a personal interest in them as individuals. The first objective of study was to determine whether patients with injuries in acute care beds are met higher needs. The second objective was to compare the satisfaction of higher level needs in hospitalized patients with injuries in acute care beds by age and sex. The third objective was to determine the knowledge of nurses of higher human needs, and whether nurses are concerned about meeting needs in patients hospitalized with injuries. The survey was carried out quantitatively using the questionnaire method of data collection. Questionnaires were distributed to 55 nurses working in surgical departments of České Budějovice Hospital, plc, and Tábor Hospital, plc, and to 60 patients hospitalized with injuries in surgical departments of the same hospitals. The results of the quantitative research were evaluated using graphs. In accordance with the study objectives, the following hypotheses were stated: Hypothesis 1 Patients hospitalized with injuries in acute care beds show a need for meeting higher level needs. This hypothesis has been confirmed. Hypothesis 2 Nurses are concerned about meeting higher level needs of patients hospitalized with injuries in acute care beds. The hypothesis has been confirmed. Hypothesis 3 Women hospitalized with injuries in acute care beds have a greater need for meeting higher level needs than men. This hypothesis has been confirmed. Hypothesis 4 Elderly patients have a greater need for meeting higher level needs than younger patients. This hypothesis has been refuted. The findings obtained by the research could be used as information for the middle management of the hospitals departments where the research took place and the creation of educational material for nurses working there because it is important to learn more about the needs of patients in order to facilitate and improve meeting their needs.

Propagation of inclined cracks to the interface of ceramic laminates
Novotná, Lenka ; Trunec, Martin (referee) ; Chlup, Zdeněk (advisor)
Composite materials with laminated structure provide advantages which are utilised during component design. Low density, temperature and chemical stability are the profitable properties predetermining application of ceramic laminates. The main obstacle for wide spread of ceramic materials is their inherent brittleness. Therefore, in this thesis, the crack propagation in ceramics laminates has been extensively studied. Laminated structures with various volume fractions of components (alumina and zirconia) were prepared by electrophoretic deposition. Evaluation of crack propagation through the interface and determination of basic mechanical properties was conducted on the basis of extensive literature search. Crack deflection originated in both presence of internal stresses and differences in elastic modulus during the crack interface passing was monitored. A special type of specimen geometry was employed with the aim to set arbitrary angle between crack and interface. It was experimentally found that the degree of crack deflection is dependent on entering angle and volume fraction of components. Higher crack deflection was already found in the bulk of the test piece comparing to the test piece surface. The 3D fracture surface reconstruction generated using laser confocal microscopy was used in this detailed crack propagation study. Further basic elastic and strength characteristics of laminates were determined and compared to those obtained from monolithic materials. The validity of the mix rule for elastic characteristics was confirmed by comparing of elastics modulus. The most reliable method for elastic modulus determination was marked the dynamic resonance method due to low scatter and consistency in measurement. The flexural strength of all laminates tends to be close to the flexural strength of the weakest component. Therefore the mix rule is not applicable for flexural strength estimation on the contrary of elastic characteristics. The change of component volume fraction leads only to change of flexural strength scatter. Thanks to gained knowledge about crack propagation and basic characteristic determination will be possible to design ceramic laminates more efficiently for given needs of application.

Differences between men and women in the Czech labour market
Stroukal, Dominik ; Kadeřábková, Božena (advisor) ; Pavelka, Tomáš (referee) ; Němec, Otakar (referee)
This thesis consists of five articles that apply current world research on labor economics at the Czech Republic and confirms the significant differences between men and women in this market. It shows that gender has a significant influence on the preference on the labor market and, consequently, on employment and health. First, the thesis shows that preferences are relevant determinant of career and then we study the difference in preference of salary for men and women. Subsequently it shows that gender plays a significant role in explaining the relationship between homeownership, and unemployment, as well as unemployment and health. The first chapter was able to demonstrate that the preference for a career has a positive influence on the choice of career. The influence of higher education on prioritizing career proved to be positive and significant. Probability of a career choice is reduced by the presence of children, however, is not dependent on their number, which is contrary to the theory of preferences. The second chapter shows that Czech women prefer more non-monetary rewards than men. It has also been shown that people with university education are same in the preferences of non-monetary rewards regardless of the gender of the respondents, however, compared to the world's research, the Czech higher education increases this preference. It turned out that women prefer risk less than men. The third chapter demonstrates that although the housing market undermines labor mobility and employment in the Czech Republic at the regional level, therefore, that in regions with a higher rate of home ownership is higher unemployment, at the individual level, the owners of housing are unemployed are less likely. The estimates are significantly different for men and women. Men living in owner-occupied housing have a higher likelihood of employment than women. At regional level, however, this thesis shows that the high rate of home ownership increases unemployment for both men and women, in the long run only to women. The fourth chapter showed that men transition to homeownership reduces the likelihood of unemployment next year. For women, this relationship has proved to be insignificant. In addition, as insignificant showed the opposite relationship, the transition from unemployment to the newly acquired home ownership. The last chapter shows that the change in the working status to unemployment will increase in the future probability of worse health. Influence in less than two years, however, proved to be significant. An important conclusion is that men have a significantly stronger relationship between health and unemployment than women.

Ürge, Tomáš ; Hora, Milan (advisor) ; Novák, Jaroslav (referee) ; Zachoval, Roman (referee) ; Morávek, Petr (referee)
Objective: Risk of renal carcinoma is minimal 10 x higher in group of patients in terminal stadium of renal failure (end stage kidney disease - ESKD). We have only some information about chromosomal changes in renal tubules, from which rise renal carcinoma, and about pathogenesis of renal carcinoma, which seems to be different from carcinoma in common population. Aim of the study: In clinical part we valorize characteristic signs of renal carcinoma in ESKD by using of statistic methods. In experimental part we can explain pathogenesis of this carcinoma by analysis of selective chromosomal aberations. Material, methods: In 2000 - 2007 were 184 patients with ESKD in care of transplant centre and nephrologic ambulation of Faculty hospital Plze_. In 15 patients we diagnose renal carcinoma. In this group we valorize: age, gender, causation of renal failure and dialysis duration. Age, gender and type of renal carcinoma we confront with carcinoma in common population. In experimental part we valorize numerical aberations in chromosome 7, 17 and Y of tubular epithelium using fluorescent hybridization in situ (FISH). Results: We have 15 patients in average age 55.7 ± 11.5 years, long of during dialyzation was 78 ± 54 months. We do not find dependence between causation of renal failure and genesis of renal...

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell.
During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation.
The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL.
In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found.
To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Project management in selected company
POKORNÝ, Radek
This work deals with project management in chosen company. It has two parts. The first part is theoretical, which is focused to theoretical treatment of the subject. It explains what is the project, management of projects, organizations of projects, processes of project management, what is target of project, communication, control, changes and risks and more. In the practical part I focused to concrete company and project management and than I analyzed concrete project. Name of the mentioned company is OHL ŽS, a.s. It is company from Spain, which acts all over the world. In the Czech Republic has the base in Brno. This company has several divisions and every of them is focused to different professional architecture. I have chosen division of structural engineering. This division builds all kinds of buildings. It could be construction of new buildings or reconstruction. To analysis of chosen project I used various business documents, contracts with investor or suppliers, document which include billing, timetable. I especially used my experience with projects of this company, and I was part of this project. Name of this project is Reconstruction of cladding including replacement windows and insulation. During the analysis of project I found a couple major gaps. If we could avoid these gaps, we could increase profit. These graphs is especially in management. At the beginning there were appointed two temporary construction managers. They doesn't care about result project, because they knew that they will not be to the end of the project. These gaps are because there is missing motivation system. Project manager can´t affect results of employees. It doesn´t depend on performance of employees, they always has the same wages. For elimination of these gaps I proposed several suggestions for improvement. The first suggestion is modification and extension of motivation system. New motivation system include personal evaluation. This evaluation depends on performance of employee. The second part is bonus from over profit. The next suggestion is make a new working position. This position would take care about controlling and project documentation. During the building project, especially at the end is construction manager very busy. It depend of decision of construction 63 manager what kind of activity will have prefer. Project documentation and administration or controlling of building works. If they are doing everything correct and technology are respect. Suggested position would take care about invoices, real work, which is done, project documentation, controlling of budget. The third suggestion is purchase of small machinery such as chipping hammers and drills. At this time they rent all devices. Rent is higher than purchase price. The last suggestion is use credit to restoration of fleet. At this time they have obsolete fleet, because the bought all cars by cash. It is not conveniently.

Use of e-learning education of universal nurses in Militari university hospital - University hospital Prague
JANKŮ, Kamila
The diploma work submitted is called The Use of E-Learning Education of Nurses in the Central Military Hospital Military University Hospital Prague. The theoretical part of the diploma work deals especially with the significance of e-learning, distance learning, history of education of nurses in the Czech Republic and e-learning in health care. In addition, the work includes information of the Central Military Hospital and describes its present circumstances and use of e-learning in the working process. 5 aims and 4 hypotheses were set for the quantitative research. The first aim was to determine the time demands of the e-learning courses study. The second aim was to determine the attitude of general nurses to e-learning education. The third one focused on contribution of e-learning education for general nurses and for the hospital management. The last aim focused on satisfaction of general nurses with the form, contents and diversity of e-learning courses. The fourth aim was used to determine reasons leading for development of e-learning courses for general nurses. Four hypotheses were determined: H1: It takes less time to complete e-learning course studies than regular studies. H2: Nurses younger than 30 years of age prefer e-learning education unlike nurses older than 30. H3: The effectiveness of regular studies is better than the effectiveness of e-learning education. H4: E-learning courses are not as financially demanding as regular courses. The data collection technique consisted in our own anonymous non-standardized questionnaire containing 32 items. The research file consisted of 212 general nurses working in clinical departments of the Central Military Hospital. An additional method was based on a dialogue with the Education Team Manager of the Central Military Hospital. The research results related to the hypotheses show that completing e-learning course studies does not take less time than completing a regular course. Nurses younger than 30 years of age do prefer e-learning education contrary to nurses older than 30. The effectiveness of regular courses in contrast to e-learning education has not been confirmed as well as the fact that financial demands of an e-learning course are lower than financial demands of a regular course. Further, nurses prefer regular forms of studies, mostly with their passive participation in an educational event; however, they find completion of e-learning courses more convenient. Most respondents also expressed a positive opinion on the form, contents and diversity of e-learning courses. Courses include enough information for preparation of a final test and nurses find the number of courses necessary for periodical evaluation adequate. What they consider limiting is the impossibility to retake the final test; they mostly suggested it should be allowed to take the final test twice or three times. The research implies that a higher percentage of the respondents spend as much time as they want studying. Nurses still prefer regular forms of studies with passive participation to the e-learning form. Most nurses have a positive opinion on the current contents of courses in the form of a text format. The course topics are mostly based on suggestions by members of the Non-Medical Professions Education Team of the Central Military Hospital. The research results will be presented at the next regular meeting of members of the Non-Medical Professions Education Team of the Central Military Hospital. Procedures for improvement of the form of the current courses will be presented and proposed as well as the possibility to develop communication between the author and students, the limiting impossibility to retake final tests and the suggestions concerning the number of possibilities to retake them.

Vliv teploty vody a intenzity světla na raný vývoj sumečka afrického v komerčním chovu
PROKEŠOVÁ, Markéta
The successful production of quality early fish stages is crucial for artificial rearing fish species. Nevertheless, it is quite a problematic process, because fish as poikilothermic organisms are highly sensitive to various environmental conditions. Moreover, both fish embryos and larvae are more affected by biotic and abiotic factors (such as predation, stocking density, temperature, light, pH, salinity, oxygen saturation, feeding availability, or their interactions) than older juveniles or adults. Most fish processes such as reproduction, metabolism, survival, development and growth can be considerably (positively, negatively or not) influenced by these conditions. Therefore, it is important to understand their impacts on fish stages during embryonic, larval, juvenile, adult, and eventually the senescent period. Then, following the application of new knowledge to the practise, especially species- and age-specific optimal conditions, should result in higher survival, better growth rate, well developed fish without deformities and lower cannibalism. The objectives of the present thesis were to assess the effect of water temperature and light intensity on the early development (embryonic and larval period) of African sharptooth catfish as a perspective fish species for freshwater intensive aquaculture. Due to its great characteristics (for instance fast growth, ability to breathe atmospheric air, rearing at high stocking density) this species can meaningfully contribute to the global aquaculture production which is expected to rise in the coming years. However, there are still some difficulties in the early rearing African sharptooth catfish regarding the cannibalism, feeding, survival and necessity of detailed information about the effects of some abiotic factors and their interactions.

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.

Economical evaluation of investments and risk analysis in real enterprise
Götz, Miroslav ; Fotr, Jiří (advisor) ; Špaček, Miroslav (referee)
The aim of the work is to introduce various ways of economical evaluation of investments and present their practical application for industry branch of electrical devices. The work is divided into two parts: theoretical and practical one. The introductory part presents framework of economical evaluation and describes basics of economical evaluation and terms such as NPV, discount rate, investment decision) The work focuses on the most favorite approach -- discounted cash flow method - of economical evaluation of investments in detail. However, practical experiences show that conventional approach does not take probability distributions of input variables into account. When the higher risk is implied to discount rate, promising project could be rejected. That is why DCF concept is complemented by Monte Carlo risk modeling application.
