Demography and Dispersal Ability of a Threatened Saproxylic Beetle: A Mark- Recapture Study of the Rosalia Longicorn (Rosalia alpina)
DRAG, Lukáš
This thesis focuses on demography and mobility of an endangered and strictly protected icon of European saproxylic biodiversity, the Rosalia longicorn beetle (Rosalia alpina). Using the mark-recapture method we estimated the size of the population, adult longevity, and dispersal ability of the Rosalia longicorn on three hills in the Ralska Upland, Czech Republic. Furthermore, we assessed the distribution pattern of another 15 populations inhabiting small patches of old beech forest in this area. Factors affecting local survival and the species conservation are discussed.

The impact analysis of the technical devices used by the driver on the reaction time
Kubánek, Ondřej ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
This master‘s thesis analyzes the impact of the use of technical equipment for the driver reaction time. There are described the legal requirements for the use of technical devices by the driver in the vehicle. There are analyzed the types of technical devices used by drivers and mainly discussed the issue of drivers' reaction times. They assessed factors affecting reaction time, ways of measuring the reaction time and the type of reaction times. They discussed earlier research from the beginning of the measurement of reaction times to the latest research, dealing with the measurement of reaction times when using a mobile phone. The practical part is devoted to perform road tests on a sample of drivers and evaluate their reaction times during normal driving and during a call. The measured and evaluated data are commented with respect to the benefits of expert activities in the field of transport.

Optimization of network flow monitoring
Žádník, Martin ; Lhotka,, Ladislav (referee) ; Matoušek, Radomil (referee) ; Sekanina, Lukáš (advisor)
The thesis deals with optimization of network flow monitoring. Flow-based network traffic processing, that is, processing packets based on some state information associated to the flows which the packets belong to, is a key enabler for a variety of network services and applications. The number of simultaneous flows increases with the growing number of new services and applications. It has become a challenge to keep a state per each flow in a network device processing high speed traffic. A flow table, a structure with flow states, must be stored in a memory hierarchy. The memory closest to the processing is known as a flow cache. Flow cache management plays an important role in terms of its effective utilization, which affects the performance of the whole system. This thesis focuses on an automated design of cache replacement policy optimized to a deployment on particular networks. A genetic algorithm is proposed to automate this process. The genetic algorithm generates and evaluates evolved replacement policies by a simulation on obtained traffic traces. The proposed algorithm is evaluated by designing replacement policies for two variations of the cache management problem. The first variation is an evolution of the replacement policy with an overall low number of state evictions from the flow cache. The second variation represents an evolution of the replacement policy with a low number of evictions belonging to large flows only. Optimized replacement policies for both variations are found while experimenting with various encoding of the replacement policy and genetic operators. The newly evolved replacement policies achieve better results than other tested policies. The evolved replacement policy lowers the overall amount of evictions by ten percent in comparison with the best compared policy. The evolved replacement policy focusing on large flows lowers the amount of their evictions two times. Moreover, no eviction occurs for most of the large flows (over 90%). The evolved replacement policy offers better resilience against flooding the flow cache with large amount of short flows which are typical side effects of scanning or distributed denial of service activities. An extension of the replacement policy is also proposed. The extension complements the replacement policy with an additional information extracted from packet headers. The results show further decrease in the number of evictions when the extension is used.

Do Consumers Really Follow a Rule of Thumb? Three Thousand Estimates from 130 Studies Say “Probably Not”
Havránek, Tomáš ; Sokolova, Anna
We show that three factors combine to explain the mean excess sensitivity reported in studies estimating consumption Euler equations: the use of macro data, publication bias, and liquidity constraints. When micro data are used, publication bias is corrected for, and the households under examination do not face liquidity constraints, the literature implies no evidence for the excess sensitivity of consumption to income. Hence little remains for pure rule-of-thumb behavior. The results hold when we control for 45 additional variables reflecting the methods employed by researchers and use Bayesian model averaging to account for model uncertainty. The estimates of excess sensitivity are also systematically affected by the order of approximation of the Euler equation, the treatment of non-separability between consumption and leisure, and the choice of proxy for consumption.

The contributions of the sections (NACE-CZ) to the creation of gross value added
BEDNÁŘOVÁ, Monika
The aim of this thesis was to evaluate the contributions of the sections (NACE-CZ) to the creation of gross value added. The first part of this thesis described the theoretical concepts relating to national economic gross value added. Analytical processes were used for the calculations, which may be used only if we are dealing with an additive link between individual factors. The sections' contributions to the creation of national eco-nomic gross value added were evaluated in the practical part, on the basis of the proc-esses set forth in the methodology. In the given time horizon, contributions by institu-tional sectors and groups of sections classified according to the level of technology showed a certain dependency on the actual economic cycle. Although the strongest in-stitutional sector is non-financial enterprises, they were the ones most affected during the crisis period, together with government institutions. On the contrary, the financial institution sector showed a strong position during the crisis period. In terms of the grouping of the sections according to the level of technology, the greatest contribution to national economic gross value added is by groups B1 and B2. The influence of the economic cycle was noted in all the groups but, according to the results, group C did not react quite as sensitively as the other groups.

Specificity of insect-plant associations and their role in the formation of plant defenses and speciation
VOLF, Martin
The aim of this dissertation is to investigate what role insect-plant interactions play in the formation of host-plant defenses and in the diversification of both groups. We show that various groups of herbivore respond differently to host-plant defenses. Therefore plant defenses diversify into suites of complementary traits, as individual traits fail to provide protection against specialized herbivores. Further, we identify what levels of host-phylogeny shape the food-web structure of insect herbivores. We show that specialized herbivores are affected mainly by the terminal parts of the host-phylogeny. In contrast, more polyphagous guilds are affected mainly by the mid-levels of the host phylogeny because the effects of terminal or deeper phylogeny seem to be surpassed by other factors in more generalist insect species. In the last chapter, we show how specialized insect-plant interactions generated by tight insect-plant coevolution can influence the speciation in plants over environmental gradients.

Differentiation of offers and methods of working physiotherapy of persons with a mental or combined handicap in a practice of social service providers and another subjects.
POŠMUROVÁ, Nikola
In the Bachelor's thesis I have dealt with differentiation of tenders and rehabilitation methods. Specifically, individuals with mental or multiple disabilities and for providers of social services and other bodies. In the theoretical part I focused on defining the basic terms relating to that issue. In the introductory chapter I dealt with the definition of the concept of mental disability, causes of its creation and definition of degrees of mental retardation. The next chapter is devoted to the combined disability, specifically the yoke of the definition, causes of and classification. In the third chapter is devoted to the importance of the work, the status of the work in a person's life and the status of work for persons with disabilities, including individuals with mental or multiple disabilities in Bachelor thesis I. In the next chapter, I deal with comprehensive rehabilitation system, specifically the remedies rehabilitation, educational resources, social resources, rehabilitation, rehabilitation and special attention devoted work resources, rehabilitation, which will directly affect the Bachelor thesis. Furthermore, I determine a target group the work of rehabilitation and the preconditions for its implementation. In other chapters is devoted to the specification of tools and resources work rehabilitation, employment policy tools and I define jobs that are offered to persons with intellectual disabilities. In the practical part of the thesis, first determine the main aim and target work. The main goal was to determine what are the menus and methods of rehabilitation for people with mental or multiple disabilities with providers of social services. As the target I had set to determine what are the possibilities of transmission from individual to social services on the open employment market. Specifically, I've focused on the resources provided by the rehabilitation of daily, weekly care centers or day service center, in addition to the socio-therapeutic workshops, in a sheltered employment, and employment on the open employment market. To meet the objectives I used a qualitative approach, specifically the semi-structured interview with six providers of social services of the South Bohemian region The analysis of the information obtained, I discovered that if the device is operated daily, weekly social welfare institution or Centre, day services, the services provided are identical, not different from each other. In the case of socio-therapeutic workshops is the diversity of the wider, each device provides a variety of services, different options, some devices have socio-therapeutic workshops directly on the device, others have socio-therapeutic workshops and externally, outside of your device. Protected jobs are also in the majority of providers of social services offered both within and outside the device, always the odd jobs, such as in the kitchen, cleaning, in teahouses and the like. It always depends on the type and degree of disability, on the basis of a levy for the client to the appropriate activities. Location of the client on the open employment market is not very common in most devices, some devices that offer clients or do not provide. Partial objective was to detect transmission, I found that the only limiting factor is the client's disability that limits its options and device options, of course, that the services it offers and delivers. The aim of all devices is to achieve the greatest possible degree of autonomy of the client and allow it to advance from care centers or day service center in the socio-therapeutic workshops, found a protected job, and a job on the open employment market.

Role of the nurse in screening for depression in the elderly.
VRZALOVÁ, Monika
The diploma thesis deals with problems of depression in older people. Mainly the work is focused on identifying and analyzing the role of nurses in screening for depression in older people in primary care, acute care, long-term care and home care. This thesis was focused on theoretical direction and was used the method of design and demonstration. In this thesis was set one main goals with five research questions. The main goal was to identify and analyze the role of nurses in screening for depression in the elderly. RQ 1: What is the role of the nurse in screening for depression in the elderly? RQ 2: What is the role of the nurse in the primary care in screening for depression in the elderly? RQ 3: What is the role of the nurse in screening for depression in hospitalized patients in acute care? RQ 4: What is the role of the nurse in screening for depression in seniors in long-term and home care? RQ 5: What rating scales and methods are used in screening for depression in the elderly? The thesis introduce the concept of depression. The following are specified the causes of and the important factors that affect depression in the elderly. It also deals the differences in the clinical symptomatology of depression in old age. It explains possibilities and various barriers in the diagnosis of depression. Another chapter introduces complete geriatric examination, diagnostic classification systems, possible screening methods and scales for detection of depression in the elderly population. It also deals methods of pharmacological and non-pharmacological treatment and its possible complications associated with older age. By reason of increased suicide rate caused by depressive disorder the issue of suicidal behavior in the elderly is introduced. The next chapter deals with the nursing process, which is used by nurses in practice. It consists of the evaluation of the patient's health condition, making nursing diagnosis, creating nursing plan and subsequent implementation and evaluation. The nursing process is also needy for providing quality care. The nursing process in the stage of nursing diagnosis, introduces possible nursing diagnosis for a patient suffering from depression, which are based on the latest classification. Finally is described the role of nurses in screening for depression in the elderly in different health facilities and their contribution to the timely evaluation of depression in the elderly. This chapter introduces the role of nurses, nursing screening and collaboration with a physician. The role of nurses in screening for depression in different medical facilities is based on the first phase of the nursing process of assessment. On the basis of objective and subjective information, the nurse will assess the overall health and mental condition of the patient. Primarily, it was investigated what is the role of the nurse in screening for depression. On the basis of content analysis and synthesis it was necessary to used and processed domestic and foreign literature. A number of relevant sources are the results of various studies and Meta-analyzes, mostly from abroad, but also from the Czech Republic. The thesis can serve as a basis for nurses. The result of this thesis is to create e-learning material available for students in the Faculty of Health and Social Sciences of South Bohemia in Ceske Budejovice in the tutorial called Moodle.

Diets for food allergies
DOBRUSKÁ, Klára
I have chosen topic Diet with Food Allergy as a topic of my bachelor thesis. This illness is quite common these days. It affect infants mostly but allergy of cow´s milk protein of children under three years disappears itself mostly. There is increasing amount of causes when patient suffers more allergies. Number of people who have the most serious reaction the anaphylactic shock, icreeases. It can end with death. Doctors recommend to patients to strictly follow the elimination diet which is basic treatment of this illness. The most accurate diagnosis of illness (immunological or not) is another important factor for effective treatment. I have chosen three aims for this bachelor thesis. First to find out if patients are informed about their illness. Second to map eating habbits of people with food allergy. Third the evaluation of correctness of daily menus. I used approach of guality research. Research group consisted of six respondents with different food allergy. Those respondents wrote down their weeks menus. Menus were evaluated with program Nutriservis and it was assessed if it follows recommended dietary value. Suitable intake of energy and essential nutrients was calculated for every respondent. It was evaluated if respondents follows priciples of rational diet and if their diet contains sufficient amount of minerals and vitamins. Questionnaires were another key point of this research. Questionnaires were about illness know-how of patients and who has instructed them about it. It was found out the patients hasn´t got enough information about their illness and half of them has no idea which essential nutrients, minerals and vitamins could lack in their diet. It resulted from menus simultaneously that five of six respondents do not follow principles of rational diet and eat very monotonously. Only one respondent follows strictly elimination diet others violate diet exceptionally. Respondets would appreciate other research would focus on creation of special centres and training of doctors and nutritional therapist who would be focused on food allergies. Spreading the information about illness not only to patients but to public also is really important. Another important point is to increase amount of books about food allergies at the market.
