Arctic tundra dendrochronology
Lehejček, Jiří ; Svoboda, Miroslav (advisor) ; Monika, Monika (referee)
Historically unprecedented environmental change in the Arctic ecosystems is often given into the context of its past and possible future development. In the region where instrumental meteorological observations are scarce archives need to be investigated in order to address this issues. The comprehensive synthesis one of the archives: long-live circumpolar evergreen Juniperus communis L. shrub is presented here. 20 individuals from southwest Greenland were investigated at the cell anatomy level to understand the ecology of the species and unhide its potential for environmental and climate reconstructions. The findings are as follows:
i) Stop of exponential cross-sectional conduit-lumen widening with increasing age is in contrast with conduit-lumen nature of trees. This indicates that shrubs do not need to saturate their water and nutrient demands via traits of classical hydraulic conductivity law but rather developed different mechanisms. Extreme weather conditions result in prostrate growth form. However, different weather factors probably influence shrub growth differently: While snow and wind act mechanically (a), temperature influences the form of growth physiologically (b). a) So long as the young shrub stem has high resilience to bend back to an upright position after snow melt and so long as it can withstand the wind during the vegetation season it most likely grows upright and the conduit-lumens widen. b) Temperature, resp. freeze-thaw events are responsible for the shrubs preference of safety (finite size of conduit-lumens) over hydraulic efficiency, thus not allowing for more primary growth. All of these (and other) factors are apparently working together and the transition of vertical to more horizontal growth is gradual. As a consequence, the conduit-lumen sizes may not have to be further increased (due to ecophysiological restrictions possibly also must not) because water is no longer transported against gravity.
ii) Observed age/growth trend has to be taken into consideration for further employment of the wood anatomical parameter in paleoenvironmental studies. That is, shrub cell parameters can only be used for this purposes if correctly detrended. This allows for more accurate as well as longer reconstructions because youth trend was often neglected in reconstructions based on shrub annual-rings.
iii) The south-western Greenland Ice-Sheet (GrIS) melt rates reconstruction is presented for the whole 20th century. This part of GrIS is considered as the most active. According to the presented reconstruction current GrIS melt rates are not uncommon for the last century being comparable to first decades of 20th century. This finding is particularly important contribution to the debate on Atlantic meridional overturning circulation (AMOC). Too high fresh water inputs into the Northern Atlantic from GrIS melting may slow down or even stop the AMOC which would result in more continental climate in Europe. Presented results indicate that this threshold lies higher than observed current melt rates of GrIS.
Fascinating Juniperus comunnis species has shown to be able to address many ecological as well as environmental open questions and due to its longevity and abundant distribution has a great potential to become an important player in the Arctic research.

Epidemiological study of obesity in populations of different racial, cultural, economic and dietary background
Zelenková, Miroslava ; Lukešová, Daniela (advisor) ; Martin, Martin (referee)
Cílem práce bylo zjistit a zhodnotit, zda provedení adjustabilní žaludeční bandáže (bariatrická léčba) u morbidně obézních pacientů (BMI>35) vede k signifikantnímu snížení hodnoty BMI a dále na základě vybraných kritérií zhodnotit současnou situaci v oblasti obezity ve světě. Byly stanoveny dvě hypotézy: H1: provedení adjustabilní žaludeční bandáže morbidně obézním pacientům vede k signifikantnímu snížení BMI a hypotéza H2: existují rozdíly v hodnotách BMI v závislosti na geografick&eacu te;m původu, pohlaví, kulturních a ekonomických odlišnostech. Sledování se uskutečnila v klinickém centru ISCARE I.V.F. a. s. v Praze na pracovišti Centra pro léčbu obezity. Byla statisticky zpracována a zhodnocena data 159 obézních pacientů (BMI>35) operovaných v rámci bariatrické chirurgie metodou adjustabilní gastrické bandáže (věk, pohlaví, stupeň dosaženého vzdělání, hodnota BMI před operačním výkonem, 1. týden po operaci, 1 měsíc po operaci, 3 měsíce po operaci, 6 měsíců po operaci, 1 rok po operaci a komplikace související s výkonem a léčbou) a dále data WHO o hodnotách BMI podle geografického regionu, pohlaví, kulturních a ekonomických odlišností.
Hypotéza H1 byla potvrzena. Po adjustabilní žaludeční bandáži dochází u pacientů k statisticky významnému poklesu (P<0,05) hodnoty BMI (ze 42,27 - + 5,58 na 35,13 - + 6,0). Pokles hodnoty BMI není závislý na věku pacienta ani na pohlaví pacienta, avšak je signifikantně (P<0,05) ovlivněn stupněm dosaženého vzdělání. Nejlepších výsledků bylo dosaženo u vysokoškolsky vzdělaných pacientů. Procento komplikací (4,4%) po operačním zákroku bylo vzhledem k počtu provedených zákroků nízké. Také hypotéza H2 byla potvrzena. Byly prokázány rozdíly v z& aacute;vislosti na geografickém regionu, pohlaví, kulturních a ekonomických odlišnostech. První místo v dosažené hodnotě BMI zaujímá Severní Amerika, naopak nízké hodnoty BMI vykazují státy Subsaharské Afriky, u evropské populace byl zjištěn vyšší BMI u mužů nežli u žen v porovnání se zbývajícími hodnocenými oblastmi. Muži Severní Ameriky zaujímají první místo svou hodnotou BMI, zatímco u žen je to Střední Východ a Severní Afrika. Byl zjištěn pouze statisticky nevýznamný nárůst BMI v jednotlivých oblastech světa. Existuje signifikantní rozdíl (P< 0,05) v hodnotách BMI mezi ekonomicky vyspělými a ekonomicky méně vysp ělými státy. V ekonomicky méně vyspělých zemích existují rozdíly mezi BMI žen a mužů, kdy ženy mají průkazně vyšší (P< 0,05) hodnoty BMI oproti mužům. Obecně nejvyšší BMI vykazují státy s křesťanskou kulturou, poté státy s kulturou islámskou a nakonec státy ovlivněné buddhismem a hinduismem. U ekonomicky méně vyspělých států je dosahováno nejvyššího BMI u křesťanských států, naopak z ekonomicky vyspělých států mají nejvyšší hodnotu BMI státy s islámskou kulturou.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell.
During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation.
The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL.
In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found.
To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Antioxidant, anti-proliferative and immunomodulatory effect of fruits, vegetables and mushrooms in vitro
Doskočil, Ivo ; Havlík, Jaroslav (advisor) ; Orsák, Matyáš (referee)
Recently there has been an increasing interest in discovering of new species of plants and mushrooms which have antioxidant or anti proliferative activity. The interest is caused by the fact that these species have medicinal and food utilization. These properties of plants and mushrooms can be used when dealing with many diseases which may be connected with oxidative stress (inflammatory bowel disease, cardiovascular disease, hypertension, and tumour disease, etc.).
The thesis propounds characteristics of in vitro antioxidant and anti proliferative activity of 19 types of juices and 28 methanol extracts of fruits and vegetables, which are common parts of a diet. In the thesis there are also characteristics of 13 ethanol extracts of edible mushrooms of the order of Polypore (Popyporales). Antioxidant activity was quantifie by 2, 2 diphenyl 1 picrylhydrazyl (DPPH), oxygen radical absorbance capacity (ORAC), and inhibition of nitric oxide (NO) production. Cytotoxicity was measured by MTT (3 (4,5 dimethylthiazol 2 yl) 2,5 diphenyltetrazolium bromide. Immunomodulatory activity was determined by an assay of phagocytic activity of human neutrophil granulocytes. Further a total phenolic content (TPC) and total beta glucan content were investigated; these are considered to be the potentially active constituents participating in mentioned activities.
From the obtained results it is evident that juices (TPC = 1603.2 mg GAE/L; ORAC = 438.5 umol TE/g)
and a bilberry (Vaccinium myrtillus) fruit extract (ORAC 836.6 umol TE/g; DPPH = 404.6 umol TE/g) showed
the highest antioxidant activity of all tested samples of fruits and vegetables. Capsicum (Capsicum L.)
juices (TPC = 642.1 mg GAE/L; ORAC = 127.9 umol TE/g) and a radish (Raphanus sativus L.) extract
(ORAC 724.5 umol TE/g; DPPH = 52.2 umol TE/g) also proved to have the high values of antioxidant activity. From the tested fruits and vegetables the following inhibited to produce a nitric oxide: onion (Allium cepa L) juices (lowered the NO production by 57%), tangerine juices (Citrus reticulata Blanco)(by 52%), broccoli (Brassica oleracea var. botrytis italic) extract (by 21%), and orange (Citrus sinensis Pers.) extract (by 10%). Concerning edible
mushrooms, Lentinus tigrinus (Bull.) Fr. (TPC = 216.2 umol GAE/g of extract), Ganoderma lucidum (Curtis) P. Kras (TPC = 257.9 umol GAE/g of extract), and Royoporus badius (Pers.) A.B. De (TPC = 257.8 umol GAE/g of extract) presented the highest phenolic content. Sparassis crispa (Wulfen) Fr. (117.4 mg/g of extract) had the highest content of beta glucan. Substantial effect on phagocytic activity of granulocytes was noticed in connection with Neolentinus lepideus (Fr.) Redhead & Ginns, Polyporus squamosus (Huds.) Fr., and S. crispa. In connection with the latter of mentioned mushrooms, a moderate inhibitory effect towards HT 29 human colorectal adenocarcinoma cell line
(IC50 = 107 ug/ml of extract) was noticed.
The results indicate that the tested plants and mushrooms can be beneficial when reducing the negative effects of oxidative stress. The oxidative stress has been recognized as a contributing factor to a whole range of diseases and the reduction of the oxidative stress may lead to the decrease in the possibility of the diseases´ progression. The results show the possible favourable effects on the human health. When evaluating the results, the following fact should be taken into consideration; the in vitro tests and screenings are considered to be the first phase of systematic research of the effects and serve for the choice of respondents for further detailed studies.

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.

The Role of Nurse in the Prevention of Disease of Civilisation
PAVLOVÁ, Martina
The current state Prevention is a complex care of a patient when we are trying to prevent from the occurrence or development of a disease, or when we want to prevent from its consequences and mitigate them. Recommendations for prevention set by a doctor must be on a scientific basis, and they must be a part of all branches of medicine. Their effectiveness depends on the cooperation between patients and medical staff. The basic and most efficient method of prevention is the health promotion and health education, which is closely associated with it. The term health promotion involves a set of activities and precautions for the purpose of making health better and sustaining it. Diseases of civilisation (hereinafter "DoC") are groups of diseases which are distinguished by their association to our lifestyles. Human body is more and more threatened from unfavourable influences of external environment, such as the quality of atmosphere, work environment and environment itself, the lack of physical movement, unhealthy diet, smoking, and alcohol consumption. The list of diseases of civilisation varies and changes together with our society and the development of our lifestyles. Among the most common or frequent diseases of current time are cardiovascular diseases, which involve atherosclerosis, hypertension, myocardial infarction, stroke, coronary artery disease and obesity. Furthermore, between civilization diseases include diabetes mellitus type 2 or cancer, etc. The goal of the thesis There are two goals set for this paper. The first goal was to find out what the role of a nurse in the prevention of diseases of civilisation was. The second goal was to find out what the above mentioned role of a nurse was from the point of view of patients. Methodology For the purpose of the research part of this thesis, qualitative research using semistructured interviews was carried out. Respondents were divided into two groups; the first one consisted of eight nurses working at internal medicine and neurological department of the hospital in České Budějovice and a nurse working in a private office of a general practitioner for adult patients. The second group consisted of eight patients of the above mentioned health facilities. Results According to our findings, nurses and patients have different oppinions on the role of a nurse. Nurses in disease prevention see themselves as an equivalent to a doctor when undertaking this practice and giving guidance. The patient speaks only to the nurse who emphasized what they were told by the doctor and reiterated the main points. They make available to them leaflets and brochures or Internet resources. In contrast, most patients see a nurse as a more important source of information than the doctor. Patients have the feeling that the doctor does not have enough time or does not want to be botherd with questions. Rather the patient turns to his nurse, which they sees as more appropriate and someone to whom they can confide in without bothering. Summary The goal of the thesis was to focus on prevention, DoC, and the role of a nurse in the prevention of such diseases, as well as to study this issue, look at it from the point of view of patients and nurses via the interviews carried out in this paper, and to analyse such information. Based on this analysis are published recommendations for nurses and patients.

Effect of a graduate of field of study Special Education - tutorship in practice of providers of social care
SALABOVÁ, Jana
Theoretical part of the thesis is divided into 4 main chapters. First one deals with the helping professions generally, their definitions and definition of the Special education - Tutorship branch of study per se.It also briefly touches the subject of readiness of the future graduates to deal effectivelly with the challenges of a career in the field of social services. Chapter number two is called Special education and it defines the subject of special education itself, it's purpose and inner structure. Third chapter focuses on social services. It brings up it's definition and types and forms of social services.It also contains the examples of the institutions which fall into this category and it's providers. Chapter number four, which happens to be the last one in the theoretical part of the thesis, covers the role and purpose of graduates of the special education - tutorship studies. It brings up the definition of a social worker, necessary prerequisites as well as beneficial personality traits and feautures. In a subchapter of chapter four is a short description of a pedagogue tutor. Definition who he actually is, who are proper candidates for this position, what are desired personality traits we look for in tutors and the actual content and purpose of their work in institutions providing social services. The end of chapter four is dedicated to a position of a social worker. His activities, the position and definition of a personal assistant and again personality traits needed for a successful career in this field. The objective of the practical part of the thesis is to describe working of Special education - tutorship studies graduates in practice. Particularly their experiences "from the field", how do they evaluate the level of skill of fresh graduates during their first encounters with the reality, how satisfied are they with their choice of a career so far and what was their motivation to pursue such career. Practical part of the thesis includes qualitative research. To meet the above objectives, data collection technique had been chosen using a structured interview with the respondents, who were graduates of Special education tutorship studies. You can tell by the results of this thesis that graduates in the field of social services apply mostly to lower positions as a social service workers, even though they are qualified to perform as a social workers. The age of clients with whom the respondents work ranges from childhood to senior. The motivation that led those questioned respondents to the decision to choose the area of social services varies. Some reported that they were influenced by the actual practical experience during their studies at the university, when both the work itself and their enthusiasm for the target group played role. Others expressed they had previous experience working with people with disabilities or they just wanted to acquire new experiences. Also, involvement of a family member and their previous education was a motivation. Job satisfaction is evident from observed data, and it also contributes to work done accurately and responsibly. Personal benefits for the respondents according to findings are usually their usefulness at work, new experiences they are getting and last but not least advances of their clients. As the biggest advantage the respondents usually mention variability of their work, target group and the clients in itself and the fact, that their work is highly satisfying and they basically work in a very pleasant team of individuals. On the other hand, not exactly satisfying financial reward and challenging working hours are mentioned as disadvantages. Special education - tutorship studies - the branch they've studied, is by the majority of respondents considered to be beneficial for them and they especially highlight practical impact of practice they completed during their studies and which included visits to various relevant institutions.

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.

Oxygen therapy after cardiothoracic surgery from the point of view of nurses and patients
VRCHOTOVÁ, Klára
Cardiac surgeries are very serious surgical procedures with considerable specific features. This bachelor thesis focuses on oxygen therapy from the viewpoints of nurses and patients. Its theoretical part describes physiology of breathing and the oxygen therapy as such. It describes individual sources of oxygen and indications for oxygen administration. It also describes principles to be observed during oxygen administration. Specific aids are used for oxygen administration, particularly oxygen masks or oxygen goggles. Quality pulmonary rehabilitation is also necessary to make oxygen therapy more effective. Pulmonary rehabilitation is particularly important for patients after a cardiac surgery and it should be practiced even before the surgery. This approach is critical because in the post-surgery period the therapy makes it possible for the patient to breathe and to expectorate properly. Pulmonary rehabilitation is practiced with patients by general nurses at the cardio surgery ward, as well as by physiotherapists. There are various techniques available to determine efficiency of oxygen therapy and pulmonary rehabilitation. The techniques may be classified as invasive and non-invasive; the most frequently used non-invasive method is pulse oxymetry and the most frequently used invasive technique is blood collection for ABR. Two objectives were set for the thesis. The first objective was to map knowledge of nurses about how to provide care to patients treated with oxygen therapy. The second objective was to determine how the patients feel after a cardiac surgery. Two hypotheses and two research questions were formulated. The first hypotheses were: Nurses working at the resuscitation care station have more knowledge about oxygen therapy than nurses working at the intermediate care station. The second hypothesis was: Nurses working at the resuscitation care station have more knowledge about pulmonary rehabilitation than nurses working at the intermediate care station. The first research question was: How do the patients feel during oxygen therapy and pulmonary rehabilitation? The second research question was: How are the patients after a cardiac surgery informed about oxygen therapy and pulmonary rehabilitation? In the research part of the bachelor thesis I have used both quantitative and qualitative research methods. Quantitative processing of data was used for questionnaires filled out by nurses working in the hospitals Nemocnice České Budějovice a.s., Nemocnice na Homolce in Prague and in the faculty hospital Královské Vinohrady in Prague. The method was used for evaluation and assessment of knowledge of nurses working at the resuscitation and intermediate care wards. Quantitative methods were used for processing of data obtained through semi-structured interviews with patients after a cardiac surgery. The data were transcribed and coded using a pencil and paper method. The data were categorized based on the identified codes. Two categories were created: oxygen therapy and pulmonary rehabilitation. Each of the categories was further divided into three sub-categories. Two categories were created for the research oxygen therapy and pulmonary therapy. Three sub-categories were subsequently created for the oxygen therapy and the pulmonary therapy. The quantitative research has shown that the knowledge of nurses about oxygen therapy is higher among the nurses working at the resuscitation care ward. However, the situation is different in case of their knowledge about pulmonary rehabilitation. In this case the knowledge of nurses working at the intermediate care ward was higher. The processed data from the qualitative research have shown that patients do have sufficient information about post-surgery oxygen therapy, as well as about pulmonary rehabilitation. For all patients in the post-surgery period after a cardiac surgery the frequency of pulmonary rehabilitation was higher than 1 per day.
