Measuring phonological awareness – blend phoneme test in the beginning of schooling: an comparison of classical test theory and item response theory
Gorčíková, M. ; Šafr, Jiří
The main purpose of this paper is to show dis/advantages of two approaches classical test theory (CTT) and item response theory (IRT) to assess the level of diagnostic tools for evaluating phonemic awareness among first-grade students using longitudinal survey of children during the first grade of primary school (25 schools in Prague and Central Bohemia, 439 pupils). Phonemic awareness (FA) was measured by the task blend phonemes into syllables and words. The advantage of IRT compared to CTT is primarily a concept of independence of the test items. The probability of a response is dependent on the level of latent ability and characteristics of items. So if we know the characteristic of items parameter (difficulty) it could be estimated from the pupil´s responses the level of language skill for diagnostics. The results showed the need for blend phoneme test modifications (in particular for the end of the first grade) so as to adequately measure the high growth of FA ability levels during the first grade.

Influence of transportation on quality of delivered food (Experience of boarders)
ŽUFOVÁ, Pavlína
In this bachelor thesis I deal with the influence of transport on quality of distributed food with focus on experience of the boarders. The paper is divided into a theoretical and a practical part. The theoretical part is concerned with the HACCP system representing the preventive measures that serve for provision of health harmlessness of food in processes related to its production, treatment, storing and transport. This system is required as a part of every catering establishment. The work analyses the legislation and is concerned with duties of the operators and the persons who carry out epidemiologically serious activities while it focuses on the maintenance of their personal hygiene. In the final work I point out the potential but in fact threatening health danger of food. I classify these food risks and suggest some possibilities of elimination of such risks. The final work studies the alimentary infections that are caused mostly by wrong technological treatment or ignoring the hygienic rules. In the work I introduce and point out the hygienic requirements that should be respected, followed and fulfilled in the process and preparation of food. I further describe transport wrapping, transport of food itself and the rules of food delivery and its serving. In the practical part I use the theoretical findings from the first part of this bachelor thesis. In this part I make a brief description of the main university canteen. The K2 refectory is described in more details and I analyse the process from filling into the food containers to the process of serving the food. Simultaneously, I emphasize the temperature of particular dishes that has to be kept during the transport as well as during the process of serving. For comparison and evaluation of the results I chose a quantitative research method. This method was realised in a form of a questionnaire. I distributed the questionnaires personally to the students of the Faculty of Health and Social Studies, in building of which the K2 refectory is placed, and the students addressed near the main university canteen. The questionnaire was anonymous and contained 21 close-ended questions. Both research samples received the same questionnaires that differed only in the sequence of particular questions. In total, 220 questionnaires were handed out, 110 in each place. The percentage of questionnaires returned was 100 %. Considering the fact that I eliminated two questionnaires from the K2 refectory and five questionnaires from the main university canteen due to their wrong completing, the real percentage of questionnaires returned in the K2 refectory was 98 % and in the main university canteen 95 %. The particular data obtained in the questionnaires were further processed in Microsoft Office Excel and Microsoft Office Word. The aim of this work was to chart the experience of the boarders in the K2 refectory who consume fresh, although delivered food. The process of transportation could debase food therefore the quality of food might decrease. The experience of these students were subsequently compared with the experience of students who board in the main university canteen where the food is prepared (cooked) and consumed immediately. Based on two main goals, I determined three hypotheses: Hypothesis number 1: Transportation of food has negative influence on the sensorial qualities of food. On the basis of the statistical testing, this hypothesis was rejected. Hypothesis number 2: Students prefer fresh food. After the statistical testing, this hypothesis is valid. Hypothesis number 3: Students do not feel the difference between fresh and delivered food. This hypothesis is valid as well. The results gained and processed during my research will be presented to the university canteen staff that could use the findings in practice.

Measuring the Performance of Human Capital in the Building Company
BURIÁNKOVÁ, Irena
The main objective of this work is to measure the performance of human capital in the chosen building company. Another goal is to bring suggestions for improvement that will lead to increasing to the efficiency of human capital. The thesis consists of two parts. The theoretical part provides information from the Czech and foreign literature. Knowledge of theoretical part is then applied to the practical part. Basic information about the company is included in the practical part and comparison with competing businesses is also mentioned. But the most attention is paid to the performance of human capital, which is measured by labour productivity. Two indicators are selected for the calculation of labour productivity - sales and added value. Both indicators are compared in two ways; the first is average number of employees and the second personnel costs. Calculations are performed by internal resource of the company for the period 2007-2014.

History of critical and intensive care - past and present
HOVORKOVÁ, Nicole
The title of the bachelor thesis is "History of critical and intensive care - past and present". Its main aim is to describe its origins in order to explore the history of providing critical and intensive care, both in the Czech Republic and in a global context, and also in comparison to the current state of the medical field. This work is focused on the period of development of intensive care, from the 50s to the 80s. It is a theoretical work done by detailed research of secondary and primary sources. It is divided into two parts. The first is dedicated to intensive care and its global development and in the Czech Republic. The second part contains data about intensive care within the hospitals of South Bohemia, which I have gathered during the study of materials provided by the local archives. The first chapter and the second chapter is dedicated to the history of nursing, both worldwide and in the Czech Republic. It serves for better orientation in the next chapter. The third chapter deals with intensive care itself. It is described in many of its aspects and in its historical and global context. The fourth chapter brings us to the second part of the thesis, which is supplemented with information from archival materials found during the research in regional archives. The thesis includes some photos that were captured either during a visit to the Museum of the National Medical Library, or during visits to the archives.

Comparison of intercultural competences of nursing staff in the Czech Republic and German-speaking areas
TÝLEOVÁ, Tereza
The increasing migration of population in the 21 century causes development of multicultural societies. With the increasing number of foreigners in individual countries it is possible to also presume an increasing number of patients/clients from different cultures in medical facilities. These facts require modern attitude to nursing, developing of transcultural nursing, implementing multi- and transcultural education in the health care education and propagation of multicultural conception of nursing between the nursing personnel. The result of these necessary changes should be the ability to provide effective nursing care which is culturally adjusted to the patient/client that would also take their specifics, customs and traditions of their culture into account and that would saturate all their biological, psychological, social and spiritual needs according to their race, nationality or belief. This thesis deals with multicultural nursing and confronts cultural competence of the nursing staff in Czech Republic with that in German-speaking countries. This thesis aim is to state the level of multicultural competence of the nursing staff and explore conditions provided to the nursing personnel of the hospital for giving culturally adapted care to patients-foreigners. The results of the research give an overview of the state of culturally competent care in comparable medical facilities in Czech Republic, Germany, Austria and Switzerland. They will also give a feedback to the questioned hospitals. Such information may alert their management to possible lack of knowledge of their nursing personnel and help them direct its further education. The theoretical part of the theses defines the basic concepts regarding culture, ethnic groups, race or nation, formulates the difference between the terms "multicultural" and "transcultural" nursing, multicultural education and culturally competent care, compile the most common sections of specific cultural needs of the individuals. In short it also processes J. Campinha-Bacote's model of cultural competence in health care delivery, the Papadopoulos, Tilki and Taylor Model for developing cultural competence and the Purnell Model for cultural competence. It also shortly deals with nursing frameworks for acquiring cultural data, such as the Sunrise model from M. Leininger, the Giger and Davidhizar Transcultural assessment model and Bloch's ethnic/cultural assessment guide. The empirical part processes and evaluates data obtained during the quantitative research. The accumulation of the data was conducted through anonymous questionnaires that were distributed between the nursing personnel of internal and surgical wards of the hospitals in Czech Republic and in German-speaking countries. In Czech Republic these were hospitals in Prague and in Tábor, in Germany a hospital in Dortmund and one in Cottbus, in Austria the hospitals in Salzburg and in Weiz and in Switzerland a hospital in Aarau and one in St. Gallen. The collection of the data was conducted either on-line or by way of printed questionnaire forms. The acquired data were valorized and sorted into diagrams and tables for further clarity. From the respondent´s answers follows that the queried medical facilities in Czech Republic do not provide sufficient conditions for their workers to give culturally competent nursing care on such a level, as it is at the facilities questioned in the German-speaking areas. The results also show that language skills of the nursing personnel in these hospitals in Czech Republic are worse than those in the German-speaking countries. With the level of multicultural competence the situation is similar; in this field Czech nursing personnel does not match their foreign counterpart. It is necessary to remark that this research sample of two hospitals from each of the countries is insufficient for the results to be applied on the whole Czech Republic or German speaking countries.

Role of physical activity in the prevention of childhood obesity
VRTALOVÁ, Jana
The thesis deals with physical activity in the prevention of childhood obesity. It is focused on children, namely pupils of the eighth and ninith grades of elementary school. Obesity is responsible for more human lives than both of the world wars and if we want this epidemic of obesity and problems associated with inactivity minimized, we have to start where it is most efficient and that is with children. The main objective is to explore physical activity in a selected group of pupils. Partial aim is to determine the prevalence of overweight and obesity in the investigated group of students using somatometric measurements in the selected location. Another objective is to determine how many of childrens parents did sports in the past or actualy do sports. The final goal is to prepare educational material for students about the importance of physical activity. The work is divided into two parts theoretical and practical. The theoretical part was compiled as a secondary data analysis. Sources of data and information originated from the Czech Republic and abroad in the form of scholarly books, journals and electronic resources. The contents of the theoretical part is focused on explenation of terms such as obesity, its consequences, complications, ways to prevent obesity, physical activity, appropriate kinds of physical activity and its effects on the human body. Distinctive part is the chapter dealing with the myths of obesity some of them are really surprising. The second part is practical part and includes its own research. The investigation was conducted in a primary school Komenského alej in Žatec for pupils of the eighth and ninth grades. File featured 107 pupils. The research was conducted as a quantitative survey complemented by measurements of somatometric indicators. The data were collected using a custom non-standardized questionnaire. The questionnaire contained 14 questions and two columns separated by line for recording the exact weight and height. We checked these data at pre-agreed periods.

Management styles and their relation to the satisfaction of employees
GRAMANOVÁ, Kamila
Abstract - Leader empowering behaviours and their relation with worker's satisfaction Current state: Nurse's work is physically and mentally demanding. Adequate knowledge and skills are also needed. Nurse managers whose leader empowering behaviours administer to good functioning of medical institutions have therefore a crucial role. In these days a monitoring of job satisfaction is an upcoming matter. According to that we can look for drawbacks and problems and take corrective actions. There is a 9th year of the nationwide research of safety and satisfaction of employees of Czech hospitals. Aim: The first aim of the research was to find out what leader empowering behaviours are used the most by nurse managers. The second aim was to find out how leader empowering behaviours influence satisfaction with work conditions of nurses. Two hypotheses were given. The first hypothesis postulated that nurse managers use democratic empowering behaviours the most. The second hypothesis postulated that satisfaction with work conditions of nurses is changeable, depending on leader empowering behaviours. Methodology: A quantitative method of data capture was chosen. Non-standardised questionaires with 30 closed questions were given out. There were four questions at the beginning to identify respondents. Other set of 15 questions was focused on recognition of leader empowering behaviours. Satisfaction with work conditions was monitored in the last set of questions. Results of the research were processed into graphs and tables. Research set: The research set included nurses working under nurse managers in inpatient wards in České Budějovice a.s. hospital. The questionaire was appropriately filled in by 112 nurses, corresponding 74,7% recoverability. This was used to complete the aim of this thesis. Results: Results of the thesis were divided into two sets. The first set of questions aimed on leader empowering behaviours of managers under whom the questioned nurses of particular departments work. Democratic empowering behaviours were evaluated the most used, according to the first hypothesis. The second set of questions aimed on satisfaction with work conditions. The highest job satisfaction was reached with democratic empowering behaviours. Autocratic, liberal and nonspecific empowering behaviours were used in minimal degree and nurses reported lower job satisfaction among these behaviours. Therefore the second hypothesis was also confirmed. Conclusion: The research pointed out that leader empowering behaviours are one of the factors that influence job satisfaction. It is positive thing that an interest and research in this area increased in the last decade. Periodic evaluation of job satisfaction enables monitoring the direction of its values. According to the survey, a newsletter with recommendations for nurse managers was formed. This newsletter pointed out pros and cons of leader empowering behaviours.

Identification of species within \kur{Adelgidae} by molecular markers
VĚCHTOVÁ, Pavlína
Four molecular markers (nuclear ITS, EF1 alpha and mitochondrial AT-Rich and COI) were tested for use in species identification of Adelgidae family. Markers EF1 alpha and COI were successfuly amplified and sequenced. Aligned sequences of those two markers were used for reconstruction of dendrogram by Minimum Evolution method with Kimura 2-Parameter model. Comparison of dendrogram with assumptions based on morfology and biology of Adelgids confirmed suitability of chosen molecular markers for reliable resolution of taxonomic relationship within Adelgidae, although further testing and markers will be required to delineate sister species with higher precision.

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.

Summary of foreign knowledge about the origin and development of EDZ in crystalline rocks - research
Vavro, Martin ; Souček, Kamil ; Staš, Lubomír ; Vavro, Leona
Presented search summarizes findings of foreign research oriented on the origin and evolution of the excavation damaged zone in crystalline rocks with a particular focus on the essential results of experimental projects which were performed in Canada, Sweden, Finland, and Switzerland. The study is divided, excluding the introduction, into seven main chapters of the text, which gradually deal with: (1) definition of key terms, (2) overview of the main underground research laboratories in the world where EDZ assessment was conducted, (3) methods suitable for EDZ description and characterization, (4) main factors influencing the origin of failure around the excavations and time-dependent evolution of EDZ. An overview of important outcomes of EDZ experiments, focusing on the European hard rock laboratories (Stripa, Äspö, Onkalo/Olkiluoto and Grimsel), and their summary are presented in the final two chapters.\nThe review summarizing the published key findings and results of in situ experiments shows, that for rock in lower stress state, i.e. in no spalling environment, the extent and character of rock mass damage is typically dependent on the excavation method. Using mechanical excavation, rock damage zone with thickness less than 3 centimeters can be originated. The microcracks within this zone contribute to the increase of hydraulic conductivity of the rock mass. At some test sites (Äspö, Grimsel), where the tunnel boring machine technology was used, the damage zone was already detected in depth of less than 5 mm.\nOn the contrary, openings excavated by drilling and blasting are characterized by much more extensive damage zones up to several tens of centimeters in width. The damage progressively diminishes with the distance from the opening.
