The Pump with a Diffuser with Stochastic Blades (Runner and Diffuser)
Dobšáková, Lenka ; Melichar, Jan (referee) ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This doctoral thesis studies the non-uniform blade cascade for centrifugal pumps. Influence of non-uniform blade cascade is investigated on the impeller and diffuser. A non-uniform blading impeller of pumps in this doctoral thesis was examined in terms of influence on efficiency characteristic. The idea of using non-uniform blading is to obtain a flat efficiency characteristic. Then the centrifugal pump could be used on larger scale of power with achieving a sufficiently high efficiency. The work is based on experimental measurements and numerical simulations of non-uniform hydraulic pump components. Non-uniform impeller and the diffuser were newly designed for this research. A new measuring track of small submersible pumps was needed to design and build for measurements. Different pump combinations with conventional hydraulics on one working point and hydraulics with non-uniform were measured. All measurements were evaluated and characteristics of efficiency, head and power were obtained for each measured combination. Some of pump combinations (which were measured in experiment) were numerically simulated by program Ansys Fluent. Data needed to evaluate the characteristic of efficiency and specific energy were collected from each numerical simulation. A theoretical consideration concerns the influence of non-uniform blade cascade applied on diffuser. The suggestion how to decrease hydraulic losses in canals was done. The theoretical consideration how to make a flat efficiency characteristic was made.

Právní a zdravotně sociální aspekty činnosti OSPOD jako ustanovených opatrovníků v zámu nezletilých dětí
BORSKÁ, Jana
The Czech Republic as a signatory of the Convention on the Rights of the Child has vested the practice of state administration in the field of care for minor children to municipalities with extended powers, where the protection of the rights and legitimate interests of minor children is safeguarded by state authorities of social and legal protection of children (ASLPC hereinafter). These authorities are incorporated to the extent laid down by the Act on Social and Legal Protection of Children (Act No 359/1999 Coll., as amended). The position and roles of ASLPC and their competence and jurisdiction are also regulated by the same act. The position of workers of these authorities and its legal embodiment is equally important. Regarding professionality, there are high demands on these workers. In the Czech Republic, significant changes in legislature have been made over the past three years. These amendments have led to the strengthening of the rights of minor children and to the establishing of new tools for their protection. In connection with the adoption of new substantive regulation of family law, which is now exhaustively dealt with by the Act No 89/2012 Coll., the Civil Code, new procedural rules have been established regarding protection of rights of minor children. Such procedural legislation includes (apart from the long-existent Act No. 99/1963, the Code of Civil Procedure) the Act No 292/2013 Coll., on Special Civil Proceedings. The decision-making regarding minor children has been vested mainly by the state into the competence of courts. The courts appoint the locally relevant ASLPC as a guardian who then represents the interests of minor children. The purpose, interwoven with and derived from the first one, was to explore the opinions of selected social workers of ASLPC and of district court judges regarding the defined problems occurring during the work of ASLPCs and courts while protecting the interests of minor children. These particularly include: the use of the tool of precautionary measure; problems of different territorial jurisdiction of courts and ASLPCs; processing of complaints regarding bias in various phases of the proceedings; professional training of workers of ASLPC It is evident from the proposals of both judges and ASLPC workers that it is necessary to unify territorial jurisdiction. The courts are suggesting the priority criterion of the address where the child mainly resides. ASLPC workers suggest the official permanent residence as the prime criterion. Bias causes problems in all phases of proceedings. It is obvious that courts take differing approaches towards the solution of this problem (some courts solve the problem of bias complaints filed by the parties while other courts do not) and for ASLPC workers it is difficult to assess how to act when such complaint is raised against them. The training of ASLPC workers - workers are obliged to educate themselves and their employer is obliged to finance such training. Not all ASLPCs are able to provide training in the required extent - due to financial reasons (the average costs of education of one employee pose from 9,169 to 13,400 CZK annually and they cover approximately 6 days of training). The heavy work-load caused by insufficient numbers of ASLPC employees prevents them from completing such compulsory training. As part of the examination of the "participation of a collision guardian in court proceedings" it has been found out that irregular participation of the worker in the proceedings (absence from participation in appeals proceedings); incomplete reports (directed to courts) from surveys in families. Based on comprehensive examination of the problems of territorial jurisdiction, it was recommended that requests are independently recorded and financial compensation is provided for ASLPCs who are requested to represent minors in front of courts, to draft proposals for precautionary measures.

Are There Any Digital Curators in Czech Libraries?
Římanová, Radka ; Melichar, Marek
The development of digital repositories reveals the need for new Czech terminologies for library positions. One such job title or specialization is “digital curator”, a term which refers to a specialist responsible for digital collections. Competencies for digital curators include technical, organizational, communication, and marketing skills as well as some level of expertise in computer science as well as in information and library science. A survey of several administrators of Czech digital libraries asks how to best professionally label this group of library staff with respect to the actual activities they perform in their jobs - digital curators, administrators of digital libraries, or digital librarians? Job titles have a strong impact on higher education curricula, on the management of libraries, and also on the coordinated system of remuneration of employees at libraries, academic, and research institutions.

A nursing issue: peripheral venous catheter
TOMÁNKOVÁ NOVÁKOVÁ, Monika
Peripheral venous catheter is used to access the venous system. It is one of the most commonly used invasive procedures in health care facilities. This procedure falls within the competence and daily tasks of nurses. Therefore this type of nursing care is susceptible to risk of proceeding routinely which might result in conscious or unconscious errors. Peripheral venous catheter needs to be introduced into the patient's vein in the following cases: planned parenteral nutrition, infusion or transfusion therapy, application of intravascular medication or contrast media, rehydration, blood sampling (which can be performed immediately after introducing the peripheral venous catheter and before administrating medication) and also during an emergency care for critically ill (such as cardiopulmonary resuscitation). Nurses should be as knowledgeable as possible about this issue so that the peripheral venous catheter can be introduced well and fulfil its purpose. It is important to ensure that nurses obtain all the necessary information about their patients before inserting the catheter and that they are able to properly inform the patients about the procedure and to communicate with them. Next, nurses should be familiar with the correct procedure for inserting catheters, they should be informed about possible contraindications and know how to choose the correct type of catheter as well as where to place it. Furthermore, nurses should care for this vascular access correctly and provide the patient with enough information about taking care of the catheter after the procedure. Finally, nurses should be aware of their own potential errors and also of possible complications. Therefore they should employ aseptic technique so that they can eliminate nosocomial infections. The thesis is divided into a theoretical and an empirical part. The theoretical part focuses on the history of peripheral venous catheters and their types, indications and contraindications, necessary equipment, nursing care, complications, etc. The empirical part consists of a research. The aim of the thesis was to map the use of peripheral venous catheters in hospitals as well as to identify factors that may lead to problems among the patients with peripheral venous catheters. Four research questions were assigned to these aims. 1. What is the procedure prior to inserting a peripheral venous catheter? 2. What are the standards of caring for patients with an inserted peripheral venous catheter? 3. In which steps of caring for peripheral venous catheters do the nurses lack knowledge? What equipment do the nurses prepare in order to insert a peripheral venous catheter? The Bachelor's thesis was conducted using a qualitative research survey. The methods of collecting data included semi-structured interviews and participant observations. The research was carried out only in one hospital ward and it was anonymous. First, the data were collected by means of a semi-structured interview. The nurses were asked 14 questions (see Appendix 8). During this interview, several more subquestions were added. The results of the interviews were then grouped into several categories for the sake of clarity. The second method of collecting data was participant observation. The observed facts were recorded into an observation sheet (see Appendix 9). The same nurses who were interviewed were also observed. This Bachelor's thesis has been written in order to provide a basic overview of the peripheral venous catheters. It could be used as an information source for more experienced as well as novice nurses. The practical output of this Bachelor's thesis is a nursing care standard concerning peripheral venous catheters. This standard was missing in the hospital ward and could help the nurses to take care of these vascular accesses, to proceed correctly and eliminate possible errors (see Appendix10).

A historical view of the army nurse profession.
PAVLÍKOVÁ, Andrea
The thesis deals with the profession of a military nurse. We can assert that the official study of military, non-medical health-care related qualifications and its use in practice not only for military purposes dates back to the fifties of the last century. However, women as health care professionals, consequently in uniforms, have always been an actual issue. The development of health care activities always existed, however, we must not neglect influence of scientific and medical findings. The historical timeline of development of medical care in the battle field was recorded and ranges from pre-historical healing. The way of Christian medicine was negatively influenced by the Catholic Church. The dark period of the Middle Ages had actually wrested medical performance from the hands of specialists and the suffering were left to the "tender" mercies of the priests. The following part of the thesis concerns modern medicine where enlightenment reforms were exercised. Some of the original six-month courses for military surgeons were organised in this period of time; they weretransformed into Military Surgical Academy, out of which the famous Josefinum originated. A expression of humanity which supported a form of health care of war veterans was demonstrated by constructing buildings for invalid people. The second half of the nineteenth century is characterized by the phenomenon of the presence of nuns in military hospitals. This study goes further in depth of professionally organized healthcare right in the battle field, which dates back from the era of wars in the Crimea.This stage describes the transformation of caring into nursing which requires the necessity of specialized preparation of persons providing nursing practice. In addition, Henry Dunant engraved himself into the history of the profession of a nurse, as the founder of the Red Cross, who first trained health care professionals for working within armed intentions of the state. The continuation of this action sketches out the process of providing first aid in principal armed conflicts of the twentieth century. It describes the functioning of commander operated military health service of that time. WWI drove Czech medical staff to both sides of the front where they provided medical help to the injured. Nurses of the WWII already performed their duties in uniforms as the rightful members of the army. The thesis also mentions post-war usage of military health care professionals in secret foreign missions and their specialized erudition.Last but not least, it marginally discusses contemporary possibilities of modern health care service of the Army of the Czech Republic. The goal of the endeavours of writing this thesis was to chart out clearly the development of the profession of a military nurse within the historical context, focusing mainly on women coming from Czech regions. In order to make the history background concerning specific female participants of the world war conflicts understandable to the reader, this paper reports, in broader extension, peculiar medical and nursing findings, already from the era of prehistoric civilisations. The history study method were applied for the purpose of the theoretical thesis. The methodology is based on searching, studying, sorting and the consecutive systematic objective describing of the events from the past times with the intention to propose comprehensive report on the subject given. It was necessary to study inexhaustible amount of sources to obtain awareness of historical connections. Factual information was derived by analysing of primary and mainly secondary documents. The thesis sketches out histories of military health care and the profession of a military health care professional stemmed from the exploration of appropriate written sources and conclusion of the basic findings. The intentions of the work are not only to clarify the past but also to contribute to solutions of every-day issues.

Supervision in psychiatric nursing
RŮŽIČKOVÁ NEUŽILOVÁ, Michaela
Basic theoretical background The theoretical part of the thesis explores the issue of supervision and focuses on psychiatric nursing. It is divided into several parts. The first part is focused on supervision, briefly characterizes supervision as such, then it describes its divisions, functions and methods. It also explores the participants of supervision, the agreement on supervision, transcultural supervision and Balint groups. The following part describes historical development of psychiatric nursing, briefly presents the personality of Joyce E. Travelbee. In the conclusion of the theoretical part of the thesis the problems of education and competence of nurses in psychiatric care are introduced, marginally mentioning the Turku declaration. The aim of the work The main aim of the thesis is to investigate the awareness of nurses working in psychiatric care of the clinical supervision options. The task of the second objective is to find out the opinion on supervision of nurses working in psychiatric care. The third objective is focused on means to assist nurses working in psychiatric care in their personal development and growth within their practices. The purpose of the fourth objective is to find experience with supervision of nurses working in psychiatric care. The methods used Qualitative investigation was chosen for the empirical part of the thesis. The method used for data collection was in the form of semi-structured interview. The interviews with the respondents were taken down using a voice recorder and transcribed, qualitative data was then analyzed by pencil and paper encoding technique and semantically organized into 27. groups of categorization. The selection of a research sample was intentional, consisting of twelve nurses working in psychiatric care in the Czech Republic. Results The research focused on nurses who do not have personal experience with supervision revealed that they have certain awareness of the supervisory process, however not quite sufficient to be able to describe the nature and function of supervision in its entirety. Their knowledge is rather theoretical. They understood supervision as help to solve disharmonious relationships in the workplace, as well as it could improve communication skills of the nurses, it would also assist in dealing with crisis intervention and prevent burnout syndrome. The results regarding nurses who do not participate in the supervisory process clearly indicated that they have insufficient support and the opportunity for both their professional and personal growth in their workplace, while this important could be solved by supervision. The research, which covered only nurses who have had personal experience with supervision and regularly participate in it, showed that their knowledge and skills related to the supervision process are quite sufficient to be able to understand and use supervision practically in the whole range. These nurses sees supervision as a benefit that would allow them not only to understood themselves, but also to learn how to manage challenging situations that are a part of their profession. Supervision gives them confidence, provides support and teaches them to deal with people who are part of their work process. Supervision has become a tool for preventing burnout and showed them how to use their own potential effectively. Conclusion This thesis is focused on the use of supervision in psychiatric nursing. Working with mentally challenged patients is very demanding, therefore supervision plays its justified role there. If you do not know yourself and you are not able to solve your own problems, you can never effectively and comprehensively address the problems of others, who are often desperately waiting for your help. The results will be presented at professional seminars designed not only to nurses working in psychiatric care.

Students´ motivation for the work in social sphere
DUCHOŇOVÁ, Kristýna
The topic of this bachelor thesis is the motivation of students to work in the social sphere. Selecting a domain is an important milestone in the life of each of us, the aim of the work is to determine what factors affect the young person during the election field with a social focus and how his motives during his studies and during his practical experience varies.The work is divided into two parts, theoretical and practical. The theoretical part describes the social work and its history, definition, ethical standards and goals. The work deals with the role of a social worker and describes his competence. Presents preconditions for occupational choice and the factors that influence this choice. It also deals with motivation, defines it and acquaints us with concepts such as motive, value or need. Work is affected by motivation theories and recalls the hierarchy of needs of Maslow. In the seclusion does not stay the work motivation in helping professions, questionable motives or burnout, which occurs currently in the social sphere more frequently than in other sectors. The practical part is focused on quantitative research, when the survey begins with primary school pupils who have just chosen their future focus. This part aims to determine what percentage of these students opted for the social sphere and what lead to this decision. Further quantitative research conducted among high school and college students who attend branch with a social focus. Here, the work reveals the most common and most important motives of students, satisfaction with the chosen field of study and their expectations of future studies and career. Here we will also learn how many students want after graduation stay in the field. In the practical part there is also a qualitative research, which complements the whole job. Semi-structured interviews are conducted with students, but also with a social worker. These respondents describe us closer their motivation for working in the social sphere. According to the results which this research brought, it can be stated that most of the students choose a subject with a social focus to have the opportunity to help the others. But is true that many students are choosing a school prematurely and are influenced by the place of residence, their friends or the nature of the study, most of these people don´t know what they can expect from the field and are often discouraged during their studies. From this work could in practice benefit pupils and students who decide for the field of social affairs. For teachers working in schools where the research took place,could this work serve as a feedback. Especially the part which describes the differences between expectations and reality can be used.

Pick´s disease and the specifics of the nursing care of a patient with this disease
KOPKAŠOVÁ, Lenka
Pick's disease is a degenerative-atrophic process that primarily affects the frontal and temporal lobes of the brain. Besides Alzheimer's disease, it is a lesser known form of dementia which affects people of younger age. Although the exact range of Pick's disease occurrence varies in the literature, the average reported age is between 50-60 years. The disease can change eating habits, cause emotional swings, inappropriate behaviour and sloppy appearance of the patients. The behaviour to others is often selfish, the patients are unable to listen to others and ignore their surroundings. Pick's disease is also characterized by inappropriate sexual behaviour. Globally, the number of dementia patients is still growing and according to expert guesses the increase will continue. Nursing care for patients with dementia is therefore becoming a very actual topic as dementia is called a quiet epidemic of our century. Nurses in their departments quite frequently encounter patients suffering from dementia of various origins at different stages of disability and the staff at healthcare facilities often regard these people as a burden. The aim of this thesis, which is called Pick's Disease and Specifics of Nursing Care for Patients with this Disease, is, based on the theoretical knowledge, to map definitions and diagnosis of Pick's disease, to define the needs of such a patient, and to list the most common problems in the nursing care. It focuses on people with dementia within medical facilities. For proper understanding of the problem, the thesis starts with the anatomy and physiology of the brain and the description of cognitive functions which are affected by the dementia syndrome and the definition of dementia. Based on the studied literature, dementia is divided according to various criteria. It has been found out that dividing dementia is not entirely uniform, but the essential facts and overall opinions of the authors do not diverge. Pick's disease belongs to a group of frontotemporal dementia and its position in this group has changed over time, as it is recorded in the literature. The thesis includes recommendations resulting from the studied literature in the approach to patients with dementia and emphasizes personal communication with the patients and empathetic and humane approach. Although medicine cannot prevent dementia, an early diagnosis of a specific type of dementia and correctly targeted treatment can increase the quality of life not only of the patients but also of their families. I have chosen this topic because I find it very current and interesting. During my nursing practice at the Surgery Department and Aftercare Department, I have met patients suffering from dementia and I did not know how to properly and efficiently communicate with them. For the theoretical part of my work, the methods of explanation, synthesis and induction on the basis of Czech and foreign information sources have been used. The most frequently quoted Czech authors in my thesis are doc. MD. Roman Jirák, PhD., the head of the center for diagnosis and therapy of Alzheimer's disease at the psychiatric clinic of the General University Hospital in Prague, the 1st Medical Faculty of Charles University. This thesis can serve as an informational and educational source both for nurses and the general public who may experience the disease within their families. It would be considered a great success if it helped nurses or family members to diagnose Pick's disease or other dementia at an early stage.

The assessment of equine housing systems in terms of welfare
Morávková, Kateřina ; Hofmanová, Barbora (advisor) ; Majzlík, Ivan (referee)
Nowadays, the conditions of animals' breeding are better than they were in the past and bigger emphasis i sput on their compliance and improvement. To secure/provide a good welfare is not an easy task for the breeders. Generally, we know how good welfare should look like, but we do not know, if the animal is satisfied. Various studies and experiments of good and bad life conditions appear. On the other hand, there still are lots of things about the welfare topics, which could be discovered and explored. Other question is, if a bad welfare has something common with animals' cruelty, or does not. One of categories, which is welfare focused on is stablig. When horse breeding and stabling, we should consider their native lifestyle and behaviour. We should do this, if we want to secure a good welfare. In many of cases there is a problem, because as it has been said, there is no strict rule, what is a good and bad welfare. Some horses can be satisfied in a box, and the other can feel bad in the box -- they can have depression and they will feel best when they are out with other horses. Every system and style of stabling has its pluses and minuses. Some of the systems seem to be less suitable for horses, but it depends on the horses' character. But horses do not chooses their kind of stabling, it is choosen by the breeder. The stabling has been solved for centuries, and it must have been solved in the past, it is in the peresent, and it will be in the future. But we still come with new and improved ways of stabling. A modern guy can not imagine, that nowadays stabling should be the same as it was in the past. Today, we do not know, if this way of stabling was found as a good type of welfare and if horses were satisfied with it. It is a question, if better welfare is a box stabling or a styling out. For working horses the best stabling is the lashing one, where horses work in a wood and they want a lot of relax -- through this kind of stabling the rest can be enabled. But according to the law foals can not be roped. To stable the horse with the rope for 22 is a breach of a welfare. So we must alway take the reasons of stabling into consideration and if an exgerrated care about stabling does not verge on a horse's satisfaction. Through the behaviour and understading the horses a guy should be able to recognize, if the horse is fully satisfied and the welfare is arranged in the best way. It should be a reward for the breeders, if the horse has the good lifestyle.

Reintroduction of endangered vertebrate species in the Czech Republic
Prokorátová, Vendula ; Kubík, Štěpán (advisor) ; Vynikalová, Lucie (referee)
Reintroduction process, often also called repatriation, restoration of populations of
a certain species in areas where this specie was toner occurred. This work is focused on the evaluation of reintroduction, including problems that accompany it and its history. For succesfull renew of the population shall the reintroduction program have three phases. First of them is the reintroduction efore the surfy and the preparation phase. Following phase is the achal lunch of the species into to wild and final phase of reintroduction project is the follow-up care and monitoring. Reintroduction program should always involve experts from various disciplines and not only in science but also in sociology and specialists to communicate with the public. The success is also given by the cosi of these projects. Problems associated with re-introductions are several. Important thing is to select appropriate species for reintroduction which is not easy especially because of public opinion. Professional basis for the selection of species is the Red book but public opinion is in reintroduction programs very important and can be decisive. Attractive species get preference from the public view especially mammals and birds. Furthermore there are examples of successful reintroduction in the world in this work. The main par is focused on individual species of vertebrates which are relaesed into the wild in the Czech Republic: Ground squirrel Spermophilus citellus, Lyns Lynx Linch and Ural owl Strix uralensis. Each of these species is described in detail and it also includes conservation activities and cause sof Langer or extincting of species. Some organizations which are dealing with emergency programs in particular are also briefly mentioned.
