Serafínová, Petra ; Svatošová, Libuše (advisor) ; Jaroslav, Jaroslav (referee)
The environment is an important part of human life, which greatly affects the quality of human health and the entire population. On the quality of the environment is given ever greater emphasis, since there is an increase in the negative anthropogenic effects. To avoid these impacts or reduce their consequences should protect the environment. The important part is sustainable development in order to keep a full-fledged environment to future generations.
In this thesis I analyze the main pollution by pollutants in the years 2000-2013 from all stationary sources in the district of Karvina, and from mobile sources of the Moravian-Silesian Region. Based on the statistical data of the Czech Hydrometeorological Institute, I processed an analysis of time series methods, has chosen trendy model with a forecast of future progression. For the years 2014 - 2016, I calculated the prediction of emitted pollutants.

Motivation and Stimulation of the Employees
Konvalinková, Tereza ; Margarisová, Klára (advisor) ; Pavel, Pavel (referee)
Diploma thesis clarifies issues of motivation and stimulation of employees. The theoretical part describes the basic concepts of the issue as motivation, stimulation, human resources management, communication and life situations that may arise in social work. The empirical part was examined on the basis of an anonymous questionnaire for employees in social services and interviews with executives. The main goal of the questionnaire was to find out how the employees in social services are motivated to do their work and how much they are affected by external incentives. The interview should provide a preview of executives and complete the whole topic. The group of the respondents were the employees of the home for the elderly in Libina, which provides social services to the elderly and persons with various types of dementia. The results and recommendations are given at the end of the thesis.

Detection of VPS13B gene mutation responsible for trapped neutrophil syndrome in selected dog breeds used for assistance activities
Zemanová, Lucie ; Vejl, Pavel (advisor) ; Melounová, Martina (referee)
This bachelor thesis Detection of VPS13B gene mutation responsible for Trapped neutrophil syndrome in selected dog breeds used for assistance activities starts with theoretical part and continue with experimental part, which had done in Department of genetics and breeding.
The theoretical part is focused on Trapped neutrophil syndrome and Cohen syndrome. Both of theese syndromes are caused by mutation of same gene and this is the reason, why a dog is a suitable genetic model for human disease research. Based on the theoretical part is obvious that Trapped neutrophil syndrome is a autosomal recessive genetic disease and is caused by deletion of 4 bases (GTTT) on 13th chromosome in 19th exon. This mutation is only in border collie breed. The Trapped neutrophil syndrome causes very serious problems and for individuals theese problems may be letal. If they survive, they have a very poor quality life. They have diarrhoea, pyrexia, vomite and have a typical facial ferret-like snout.
The experimental part is focused on isolation DNA from buccal mucosa of border collie breed, golden retriever, labrador retriever and Nova Scotia duck tolling retriever, than it is focused on design PCR markers and sequencing PCR amplicons.
The experimental results had confirmed hypothesis that the causal mutation is affected by pedigree and it is easy to identificate it by sequencing PCR amplicons.

Orangutans breeding and factors affecting their reproduction in captivity and in the wild
Kalkušová, Olga ; Kubík, Štěpán (advisor) ; Burešová, Eva (referee)
Information concerning orangutans living in the wild and the issue of their breeding has been summarized within the framework of this thesis. Orangutans in their natural habitats in tropical rainforests of Sumatra and Borneo are not subjected to the same influences as those bred in captivity. Their reproduction thus differs in certain aspects. Reproduction of orangutans in the wild is strongly influenced by their solitary way of life. Females are accompanied only by their young or eventually by other females and according to the studies they seek contact with males only in their period of rut. The contact is then limited to a period of time needed for copulation. One exception to this behaviour may be couples with juvenile males. After birth, the female looks after the young male for up to 8 years, having no rut during this period. The cycle of females living in the wild also shows dependency on the availability of food supply. Negative energy balance during which the cycle stops has been observed during periods of food scarcity. In the following period with abundance of food, the cycle is renewed again. The cycle renewal also occurs in cases when the female loses her young. As a consequence of these reproductive limitations females may give birth to 4 young at maximum in their life.
Guidelines have been drawn up for breeding in zoos which regulate the conditions and suitability of the exhibits so that they meet the orangutans needs. Their natural mental and physical activity is related to their health and natural behaviour. However, despite all efforts the zoos cannot provide the same conditions to the orangutans as those they would have in the wild. The forced increased socialization and contact with other individuals held in captivity may bring stress, stereotype behaviour and associated health problems which are rather frequent with orangutans bred in captivity.
According to the records in the pedigree books, the age of first reproduction and the interval between births were shorter in case of females kept in captivity. Even the keeping of males and females in one exhibit increases the probability of copulation and becoming pregnant. These changes also entail certain risks according to the studies. Breeding in captivity embodies higher mortality rate of young and adult animals. This is probably caused by young age of females at the birth and short intervals between births which are often shorter than 4 years. Females born in captivity also lack experience which they gain in the wild by learning and observing and are not able to take care of their young or refuse it later. Even females that got pregnant between the age of 11 and 14 have been described. However, such pregnancy poses a great risk for females and they die soon after birth or live much shorter. Young orangutans born in captivity were often taken away from their mothers. It is not very suitable on the one side, but on the other side, after having their young taken away from them, the females started a new, full-fledged cycle in a few weeks and could become pregnant again. However, as direct care of the young by humans has a negative effect, the young are often given back to their mothers which is successful in many cases.
Orangutans have been studied for more than 40 years and a lot of things concerning their breeding in captivity have changed during this time. Zoological gardens are trying to provide the orangutans as natural conditions as possible. It is necessary for the exhibits and the enrichment to provide enough physical and mental activities to the orangutans. Despite these efforts, the limited space and the related contacts between individuals may bring stressful situations. These are then manifested in the behaviour and health of the orangutans.

Comparison of competences and skills of higher education graduates with expectations of their first destination employers on Cambodian and Vietnamese labour market
Brtníková, Petra ; Slavík, Milan (advisor)
The agricultural sector in Cambodia and Vietnam continues playing important role in supporting national economic growth and food security. Governments together with range of local and international non-profit organisations work on crosscutting topics of development, particularly in the agriculturally profuse provinces. It creates a number of job opportunities for skilled labour. This research aimed to identify the skills and competences of higher education graduates who participated in the Erasmus Mundus exchage programme in europe in agriculture and related life sciences. It highlights the need to adopt skills and competences that graduates acquired during studies in Europe to demands of the labour market in Cambodia and Vietnam. To conduct this study, two-dimensional research was chosen. It combined quantitative survey among Erasmus Mundus alumni from Cambodia and Vietnam who participated in one of agriculture-related programmes in Europe between 2004 and 2013. Qualitative approach was facilitated using semi-structured interviews and focus group discussions with employers/HR managers and key informants from related NGOs, public and private institutions.

Application of optimization methods in hydrological modeling
Jakubcová, Michala ; Máca, Petr (advisor) ; Hanel, Martin (referee)
Finding the optimal state of reality is the main purpose of the optimization process. The best variant from many possibilities is selected, and the effectiveness of the given system increases. Optimization has been applied in many real life engineering problems as in hydrological modelling. Within the hydrological case studies, the optimization process serves to estimate the best set of model parameters, or to train model weights in artificial neural networks.
Particle swarm optimization (PSO) is relatively recent optimization technique, which has only a few parameters to adjust, and is easy to implement to the selected problem. The original algorithm was modified by many authors. They
focused on changing the initialization of particles in the swarm, updating the population topology, adding new parameters into the equation, or incorporating shuffling mechanism into the algorithm.
The modifications of PSO algorithm improve the performance of the optimization, prevent the premature convergence, and decrease computation time. Therefore, the main aims of the presented doctoral thesis consist of proposal of a new PSO modification with its implementation in C++ programming language. More PSO variants were compared and analysed, and the best methods based on benchmark problems were applied in two hydrological case studies.
The first case study focused on utilization of PSO algorithms in inverse problem related to estimation of parameters of rainfall-runoff model Bilan. In the second case study, combination of artificial neural networks with PSO methods was introduced for forecasting the Standardized precipitation evapotranspiration drought index.
It was found out, that particle swarm optimization is a suitable tool for solving problems in hydrological modelling. The most effective PSO modifications are the one with adaptive version of parameter of inertia weight, which updates the velocity of particles during searching through the multidimensional space via feedback information. The shuffling mechanism and redistribution of particles into complexes, at which the PSO runs separately, also significantly improve the performance.
The contribution of this doctoral thesis lies in creation of new PSO modification, which was tested on benchmark problems, and was successfully applied in two hydrological case studies. The results of this thesis also extended the utilization of PSO methods in real life engineering optimization problems. All analysed PSO algorithms are available for later use within other research projects.

Using external sources in process of employees recruitment
Krouželková, Eva ; Pokorná, Jitka (advisor) ; Tereza, Tereza (referee)
At the beginning of the theoretical part, the diploma thesis deals with the concept of the human resources. In subsequent chapters characterize the progress of recruitment, together with internal and external sources of the workers, followed by the principle of selection of employees and the most common methods. The practical part consists of an analysis of current advertising options, complemented by questionnaires and verification of hypothesis. The goal of the thesis is to determine the current state of the use of social networks for recruitment and resolve whether they are able to replace the use of job portals. In terms of verification of the hypothesis was confirmed that there is no difference between recruiters who use social networks every day in personal life and those who use them several times a month. There was also confirmed that there was a statistically significant difference in the use of social networking HR aged 18-34 years and 35-54 years. The latest statistics confirmed the hypothesis that there is no difference in use of social networking for recruiters in large and small companies.

The importance of milk and diary products in human nutrition
Maroušková, Nela ; Hejtmánková, Alena (advisor) ; Michlová, Tereza (referee)
Milk and dairy products become integral part of human nutrition and belong to common food. Milk is very valuable because it contains complete proteins. Its disaccharide lactose is a source of energy. Butterfat is easily digestible. Besides potassium, sodium, magnesium, chlorine and sulfur milk contains also dietary elements like calcium and phosphorus.
Milk also contains many trace elements like iron, zinc, iodine, selenium, manganese, fluorine, chromium, cobalt, and molybdenum. Milk is an important source of vitamins. It contains significant amounts of water soluble B and C vitamins alongside fat soluble vitamins E and A and smaller amounts of vitamins K and D.
Milk and dairy products are an important source of calcium. Lack of calcium is the main cause of osteoporosis. Regular consumption of milk and dairy products may reduce the risk of cancer. Nevertheless disproportionate consumption of dairy products containing unsaturated fats can lead to higher incidence of certain types of cancer, higher risk of cardiovascular diseases and metabolic syndrome. Milk contains also compounds that prevent aforementioned diseases.
Milk is the only source of nutrients for newborn children and suckled infants. It is convenient source of nutrients in times of higher nutrient demands especially during pregnancy, nursing and senescence.
Milk, milk cream, fermented milk products, buttermilk, cheese, whey, curd cheese, whey proteins, frozen creams, cream, condensed and powdered milk belong to most important products. Fermented milk products are very beneficial to human health. Those products are sources of complete proteins, calcium, phosphor and vitamins, especially B vitamins. Lactose is decreased making fermented milk suitable for lactose-intolerant subjects. The fermentation process increases the shelf-life of the product while improving the digestibility and microbiological safety.
Milk and dairy products consumption can also have negative impact on human health. Lactase deficiency or lactase insufficient activity in small intestine results in lactose intolerance. Milk can also cause food allergy to the cow's milk.
