Clustering and regression analysis of micro panel data
Sobíšek, Lukáš ; Pecáková, Iva (advisor) ; Komárek, Arnošt (referee) ; Brabec, Marek (referee)
The main purpose of panel studies is to analyze changes in values of studied variables over time. In micro panel research, a large number of elements are periodically observed within the relatively short time period of just a few years. Moreover, the number of repeated measurements is small. This dissertation deals with contemporary approaches to the regression and the clustering analysis of micro panel data. One of the approaches to the micro panel analysis is to use multivariate statistical models originally designed for crosssectional data and modify them in order to take into account the within-subject correlation. The thesis summarizes available tools for the regression analysis of micro panel data. The known and currently used linear mixed effects models for a normally distributed dependent variable are recapitulated. Besides that, new approaches for analysis of a response variable with other than normal distribution are presented. These approaches include the generalized marginal linear model, the generalized linear mixed effects model and the Bayesian modelling approach. In addition to describing the aforementioned models, the paper also includes a brief overview of their implementation in the R software. The difficulty with the regression models adjusted for micro panel data is the ambiguity of their parameters estimation. This thesis proposes a way to improve the estimations through the cluster analysis. For this reason, the thesis also contains a description of methods of the cluster analysis of micro panel data. Because supply of the methods is limited, the main goal of this paper is to devise its own two-step approach for clustering micro panel data. In the first step, the panel data are transformed into a static form using a set of proposed characteristics of dynamics. These characteristics represent different features of time course of the observed variables. In the second step, the elements are clustered by conventional spatial clustering techniques (agglomerative clustering and the C-means partitioning). The clustering is based on a dissimilarity matrix of the values of clustering variables calculated in the first step. Another goal of this paper is to find out whether the suggested procedure leads to an improvement in quality of the regression models for this type of data. By means of a simulation study, the procedure drafted herein is compared to the procedure applied in the kml package of the R software, as well as to the clustering characteristics proposed by Urso (2004). The simulation study demonstrated better results of the proposed combination of clustering variables as compared to the other combinations currently used. A corresponding script written in the R-language represents another benefit of this paper. It is available on the attached CD and it can be used for analyses of readers own micro panel data.

Determination of content substances for selected species and varieties of roses.
Slavíková, Eva ; Sus, Josef (advisor) ; Súkeníková, Tereza (referee)
This bachelor's work is focused on comparing the most significant content substance, vitamin C, in fruits of chosen rose kinds species and varieties. Herbal products are often seen by people as products of "second choice", when failure of allopathic treatment occurs, which is focused especially on suppressing symptoms of illness, but it ignores health of the human body as whole. That's why are herbal products often alternative for therapy of chronic diseases. The base of this work is extensive literary research and results of laboratory measurings. Literary part of this work includes description of botanical classification of rose plants. There is stated basic characteristic of individual rose species and their morphological features. In following chapters is composed overview of effective substances in rose fruits and their effect on human health. In practical part of this work are included results of laboratory tests for determining ascorbic acid content for chosen samples of rose species and it also includes results of weighing and measuring of fruit samples of chosen rose species. There are also stated chosen rose species and shortly their origin and description, in the beginning of practical part. For practical part were chosen samples of species. Results of practical part are compiled into statistic tables and graphs and it confirms high content of ascorbic acid in rose fruits. This content is in range of cca 300 - 900 mg.100 g-1. Due to growing interest in alternative treatment options and "clean" natural product, it can be assumed, that many plants of Rosaceae family will keep its place in treatment practice. Those plants will be used not only for treatment of acute and chronic diseases, but also for cosmetic products production, thanks to its large effects and process options.

The subject of the dissertation is the issue of the waste management with special emphasis on the recycling of the construction and demolition waste. The recourse is an analysis of the key instruments regulating the activities and behaviour of market operators in this field toward fulfilling all-society priorities and principles of the sustainable development, where special accent is put on the area of subsidy policies and programmes. The aim of the dissertation is to analyse and evaluate the setting of the selected subsidy programme in terms of economic and ecological efficiency with the emphasis on the assessment of the impact on the recipient. The subject of the research will be a priority axis 4 "Improvement of Waste Management and Removal of Old Environmental Burdens" within the Operational Programme Environment 2007 - 2013. In the literature review basic concepts and important definitions are defined, followed by the comprehensive and complex searches of the problematics from different angles of view. First of all, the global aspect of environmental protection is discussed, broader historical, legal, economic and political contexts, that are essential fundament for understanding the current and future challenges both globally regionally, are summarized. Hereafter, a more detailed description of the situation of the European Union is followed, then the overview is completed by a detailed view at the state of the problematics in the Czech Republic. Subsequent chapters are devoted to a detailed analysis of the waste management sector, again in terms of global, European and national standpoint, in the end the view is focused on the key issue of the dissertation problematics of construction and demolition waste. In the application part the fulfilling of the stated objective of the dissertation through four defined hypothesis is solved. Hypotheses verify the efficiency and appropriateness of the setting of the system of subsidies in the frame of the monitored programme.

Kolařík, Tomáš ; PANOCHA, Jiří (advisor) ; TOMÁŠEK, Jiří (referee)
In his master thesis the author provides a look into the history of The North Czech philharmonic Teplice, the only professional symphonic ensemble in the region of Ústí nad Labem, since 1948 until now. The work is divided into four main chapters. The first one gives an overview about the most significant conductors, which held a position of either a chief-conductor or a deputy. The second, crucial chapter brings an insight to the historical development of the orchestra, its changes and events, from the time of the re-establishment (1948) to the year 2016. In the third chapter, the author mentions the most important information about Ludwig van Beethoven music festival, of which The North Czech philharmonic Teplice is an organizer, and then gives a brief and incomplete list of the festival's seasons. The final chapter marginally sums up the work with the information about a new feature called "orchestra academy", inspired by the main czech orchestras. The thesis is attached with pictures showing the rehearsals and concerts environment in the time course and recent images of the orchestra, which enhance the possible plain and fact-like character of the whole work.

Characteristics of the working behavior of Czechs and Ukrainians
BYKOVA, Sofia
The aim of this work is to create a transparent and comparable characteristics of the work behavior phenomenon within the cultures of those states - what is common and what is different between them, or maybe incompatible .It is supposed to have some analysis of possible conflicts and their connection with the mentality. The primary reason of this aim choosing is the specialty I study. My work contains information that could be interesting and useful not only for me and my future job, but also for managers and other employees. Overview of examined issues contains specific points, such as the fundamentals of economic psychology and behavioral economics (symbiosis of psychological and economic opinion on motivation and rationality of individuals), theories of motivation and reaction to different occurrence, characteristic of the term "mentality", general points about the human impact of the world economy. For realizing the goals of my work the following hypotheses have been proposed - Czech and Ukrainian mentality have significant differences, though these cultures are close. - Ukrainian and Czech employees are able to work effectively in a team and find a "common language" in the workplace. The difference in mentality does not obstruct on it. - Employers could be interested in the Ukrainian employees taking into account their high concernment and motivation. All three of the hypotheses were confirmed by observed data and comparison of mentality characteristics. Czechs are often tolerant to other cultures, moreover Ukrainian culture is not much different and does not create difficulties in the working relationship. Based on the fact that the chosen company has no conflicts associated with work behavior and differences in mentality, it's hard to define my contribution to this organization work.

Role and competences of the nurse in compared with Czech Republic and Namibia
KLYNCYPAROVÁ, Hana
Theoretical grounds The nursing profession among the professions and mission. Job nurse is one of very important professions. Nurse is an independent worker who has an irreplaceable role in the provision of care. In practice, certain roles, such as the role of a caregiver, the educationalist, communicator, the role of the lawyer, consultant, person, who brings the change, manager and researcher. These roles are constantly interacting and are interconnected. Health care has multidisciplinary and multiprofessional character. Although each of these professions contribute to care in a unique way, all share certain skills that are necessary to ensure the quality of care. Over the years there have been increasing professional skills and increase competencies. Expanded the range of services for which they previously did not have the competence or sisters had a written authorization of a doctor. This work is made up of theoretical and empirical part. The theoretical part provides an overview and information on the field of nursing and its history, dealing with the care system and education system in the Czech Republic and Namibia. The following list of findings roles and their importance in the nursing profession. The last part deals with the competencies of nurses in both countries. The aim of the thesis: The aim of the study was to determine the roles and responsibilities of nurses in the Czech Republic and Namibia. To to obtain this information were chosen research question what role nurses advocate in the Czech Republic and Namibia, and what are nurses in the Czech Republic and Namibia competence. Methods: To ensure the necessary data and information was chosen qualitative research through deep interviews. Nurses who were interviewed were from a hospital in the Czech Republic and nurses from hospitals in Namibia Keetmanshoop. All interviews were recorded on a Dictaphone andwritten down on the paper. Results: Recorded interviews were analyzed after writing down, we were using paper and pencil methods. Dialogs were openly coded. The analysis of these data arose following categories: the role of caregivers, the role of the teacher, communicator, the lawyer's role, the role of counselor, role of person who brings the change, the role of leader, manager's role, the role of researcher and categories of competence. Individual categories were assigned to subcategories. All informationwere are illustrated by clear diagrams of the individual categories. Conclusion: The Research shows that nurses have a general maintenance of the roles and competencies, actually both of sides, Namibia and Czech Republic also. both groups were mostly able to define roles in nursing care. Surprisingly czech nurses most failed in the role of the Advocate, while African colleague have proven to be very informed. Research also showed negative effect of paperwork and administration in czech system. Nurses having feeling they do not provide active care as they would be able to. Czech nurses seems also low initiative and ambitious, Czech nurses do not desire for increasing competence on the other hand African nurses, who have more competencies, want still more, than they already have.
