Behavior analysis of the dairy cows with technology of milking robot
SCHESTAUBEROVÁ, Markéta
With the increasing consumption of milk and dairy products the number of dairy cows grew up also. But at the same time the requests on dairy cows were increasing which brought changes in technology and technique of the milking system which would be helpful with milk production, productivity of work and welfare of dairy cows. Milking robots could be a suitable solution. The first robot was installed on a farm in Netherlands in 1992. The aim of the bachelor thesis is to evaluate the basic behavior of Czech Spotted cattle based on analysis of their daily behavior with connection to dairy production and to the number of milking during the lactation. There were three ethological observations realized from June to December 2009 on a private family farm in Chlumeček near Křemže. The whole area of agricultural land is 320ha, out of which 120ha permanent grass and 210ha arable land. On this farm there are 72 dairy cows of Czech Spotted cattle in average, their hybrids and several pieces of Holstein dairy cows. The data were evaluated in the program Microsoft Excel and Statistica 9. The dairy cows gave attention to the feed intake most of all in September and that presents 26.07% of the whole day. It was 23.18% during the first observation in May and for the third observation in December 24.35% of the time. Standing of cows averaged 22.33% and the length of active time reached in average 4.33%. The lying duration of dairy cows were changed minimally during the year. At the first observation the lying period was 49.88%, at the second observation it was 48.25% and at the third observation 48.87% of the time. Quantity of milk per lactation was 4679kg in average; the highest productivity reached the group of dairy cows during the second lactation (4866kg of milk). Quantity of protein was 159.33kg in average with the content of 3.40%. The average number of milking reached 2.86 per day. The length of insemination interval was 103.49 days and service period was 159.97 days.

Systém odměňování v malém IT podniku
Novotný, Lukáš ; Dvořáková, Zuzana (advisor) ; Cetkovský, Pavel (referee)
The topic of this thesis is reward management and its application in a small-sized IT enterprise. Its goals are to properly document and describe current reward system in the company, evaluate the system and recommend improvements for the system. The first two goals are reached via thorough research of the company through semi-structured interviews, employee satisfaction survey, participant observation and document examination and the last one by applying principles from the current literature and education to the results of the two previous goals. The findings are that the reward system, despite growing organically instead of designed, is relatively effective in some areas, but needs improvement in other areas. The main improvement areas are motivation by contingent pay, communication management and performance management. Relatively well working rewards are especially non-financial reward connected to the work environment and work itself.

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.

Internal equity principle in the context of company strategy
Kopecký, Martin ; Nový, Ivan (advisor) ; Háša, Stanislav (referee) ; Blažek, Ladislav (referee)
The thesis deals with the scientific problem of the link between the strategic management and the compensation system using the principle of internal equity. The work is based on two pillars, namely the qualitative research and own proposed solution. The first part of the thesis describes the qualitative research and the possibilities and the synergistic effects of linking business strategy and compensation system. The qualitative research is performed as a multi-case study and investigates the phenomenon in the practice of three companies from various markets (the Czech Republic, Slovakia and Bosnia and Hercegovina) and industries (finance, IT/Telco and FMCG). The research tries to find answers to the four research questions: How does business strategy influence compensation process? How can compensation support the realization of a business strategy? How can business strategy be linked with a compensation system within the principle of internal equity? How can compensation reinforce the strategic function of the human resources management? The research is based on the study of theoretical sources as well as on practical fieldwork. The qualitative research itself uses qualitative research methods for data collection, such as observations, questionnaires, and document analysis. The population questioned was top managers, line managers and representatives of HR department. In total, 142 interviews were performed by a single person. The collected data were analyzed and the triangulation was applied. The findings were summarized and generalized into a final report that brings answers to the research questions above. The research brings valuable findings used in the second, design part of the thesis. The own proposed solution consists of two main models. The first one is a simplified scheme of the compensation system and the second one is a model of strategic segmentation of jobs. The first model could be used successfully in the business practice as well as in education. The second model of the strategic job segmentation brings answer to the question of synergistic linking of business strategy and the compensation system within the principle of internal equity. The model brings valuable findings and a foundation for further theoretical research and its further development. The model also brings practical solution to the design of related policies and processes in the strategic management of human resources. By the design of both proposed models the main objectives of the thesis were achieved.

Velké pozdní bombardování v různých místech sluneční soustavy
Zajaček, Michal ; Brož, Miroslav (advisor) ; Ďurech, Josef (referee)
In this work, we study the Late Heavy Bombardment (LHB) in the Solar System which took place from 4.1 to 3.8 billion years ago, and represents a period of intense collisions whose traces are observed on the Moon and other bodies mainly in the form of craters or impact melts. The first part of the thesis is a review on the LHB with the focus on observational evidence and recent dynamical models. In the second part, we test a particular dynamical model of the LHB using the observed cratering records on various Solar-System bodies, which was not done previously to such an extent. For this purpose, we use the symplectic integrator SyMBA, the collisional code Boulder, and various projectile-crater scaling laws. We discuss the sources of uncertainties of the observations as well as that of the models. Furthermore, we use our results to constrain the size-frequency distribution of the primordial cometary population.

: Investigation of lymphocyte populations in the porcine small intestine
Kárová, Kristýna ; Šinkora, Marek (advisor) ; Javorková, Eliška (referee)
8 ABSTRACT Historically pig is allocated to a group of animals which use certain parts of their small intestine to acquire a fully developed primary B cell reperoire. Development of such primary repertoire is independent on the antigen presence and resembles the primary lymphopoietic activity of avian bursa of Fabricius. However, some findings concernig the pig's alignment in the above mentioned group suggest otherwise. This graduation thesis is focused on the investigtion of lymphocyte populations and subpopulations in the small intestine of germ-free and conventional piglets. The aim is to determine whether the percentage amounts of lymphocyte populations is dependent on the intestinal colonization. Using Flow Cytometry the significant differences between individual samples were assesed allowing us to conclude which parts of the small intestine could possibly be used for the development of B cell repertoire. Moreover, the status of isotype switching of B lymphocytes isolated from different intestinal parts was determined by the means of PCR analysis. Our data suggest that the small intestine colonization has a crucial role in development of all the main lymphocyte populations as well as some of their subpopulations. The greatest influence of colonization was observed concerning B lymphocytes and their...

The evolutionof the picture of interpreter in selected international and Czech medias
Salajková, Linda ; Čeňková, Ivana (advisor) ; Sládková, Miroslava (referee)
The thesis focuses on the image of interpreter and interpretation in Czech printed media from 1990 to 2012. It aims to explore how interpreters present themselves in media, how journalists present interpreters and whether that image is accepted or not by the public. The thesis consists of two parts. The theoretical part focuses on methods of media and discourse analysis, definition of interpretation, formation of interpreters and professional associations in the Czech Republic. Empirical part analyses more than 800 articles about interpretation and analyses the discourse of Czech media during the period of twenty years. Analysis showed that the discourse changes constantly and the point of view of interpreters on their profession is different from the discourse created by journalists. Empirical part contains a survey which showed, that public opinion on interpreters is different from observed discourse of the media.
