Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Synchronous Formal Systems Based on Grammars and Transducers
Horáček, Petr ; Janoušek, Jan (referee) ; Yamamura,, Akihito (referee) ; Meduna, Alexandr (advisor)
Tato disertační práce studuje synchronní formální systémy založené na gramatikách a převodnících a zkoumá jak jejich teoretické vlastnosti, tak i perspektivy praktických aplikací. Práce představuje nové koncepty a definice vycházející ze známých principů řízeného přepisování a synchronizace. Navrhuje alternativní způsob synchronizace bezkontextových gramatik, založený na propojení pravidel. Tento princip rozšiřuje také na řízené gramatiky, konkrétně gramatiky s rozptýleným kontextem a maticové gramatiky. Dále je představen na podobném principu založený nový druh převodníku, tzv. pravidlově omezený převodník. Jedná se o systém složený z konečného automatu a bezkontextové gramatiky. Práce prezentuje nové teoretické výsledky ohledně generativní a přijímajicí síly. Poslední část práce zkoumá možnosti lingvisticky orientovaných aplikací se zameřením na překlad přirozeného jazyka. Diskutuje a srovnává hlavní výhody nových modelů s využitím vybraných případových studií z českého, anglického a japonského jazyka pro ilustraci.

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.

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.

Specifics of nursing care in patients after transapical aortic valve implantation.
VOTRUBOVÁ, Nataliya
Transcatheter aortic valve implantation (TAVI) is a new and an attractive method in cardiology and as well as in cardiac surgery. It is constantly evolving method which has been developed as an alternative to standard open surgery, especially in patients with severe symptomatic aortic stenosis with unacceptably high perioperative risk or patients who are not suitable for conventional open heart surgery because of age and comorbidities.A teamwork is very importantfor this new method and approach. The choice for TAVI is discussed by the institutional multidisciplinary heart team, typically consisting of interventional cardiologists, imaging-specialists, cardiac surgeons and anaesthesiologists. The first implant in a human being was performed by Cribierin 2002. In Czech Republic this method was first used in 2008. Transcatheter aortic valve implantation (TAVI) was accepted as a minimally invasive alternative to open surgery. This method does not require the use of cardiopulmonary bypass, and cardiac arrest. Other several benefits includinglower risks of bleeding and stroke events, better wound healing, less pain, as well as more rapid early recovery due to preservation of continuity of the sternumthat result in shorter durations of stay in the hospital, earlier rehabilitation and faster returns to normal life. In the presented work was used a combination of qualitative-quantitative methods of investigation. The data was obtained by using the quantitative research. The main technique was using the questionnaires designed for nurses working at the Department of Cardiac Surgery, Hospital Czech Budejovice, a. s. These results were backed up by the implementation of qualitative research, which investigated the patients and physicians view on monitored issues. Questioning method using a semi structured interview technique was used for qualitative research. The results of the survey were processed using descriptive statistics charts in LibreOffice Calc and using diagrams created in LibreOffice Writer. Qualitative results of the research were transcribed from audio recordings and coded, and the base code was created nine categories of interviews with clients/patients and three categories of interviews with doctors. The aim of this work was to explore the specific problem of nursing care about the clients / patients after transapical aortic valve implantation. On the base of our obtained data it is evident, that the client/patient after TAVI may be positioned sideways, the use of surgical drains are less frequently, so the care about the surgical wounds is simpler, patients report less pain in the surgical wound and postoperative rehabilitation and recovery is shorter. H1 - The nurses take care about the clients/patients after transapical aortic valve implantation in the same way as about the clients/patients after open aortic valve replacement, without realizing the differences between the patients treated with different approaches, was not confirmed. The nurses'sees/reported major differences in invasiveness and extent of providing care, rehabilitation, convalescent, in the duration of the hospitalization and better cosmetic effect. The results of the research can serve as a basis for creating the standards of nursing care or educational material for clients/patients. It is also possible to present the results of this work at a specialized seminar for non medical healthcare workers and results can also increase the quality of nursing care about the clients/patients after transapical aortic valve implantation.

How to prevent the proliferation of Legionella pneumophylis in hot water in the hospital Czech Krumlov
TUREK, Jan
This diploma thesis deals with microbiological quality of hot water in a hospital in Cesky Krumlov as well as hot water piping condition with respect to Legionella. It also deals with arrangements for improving the quality of hot water in this hospital. The subject and target of this thesis are the findings of the mentioned parameters based on own observations, technical documentation and analysis of warm water performed by an accredited laboratory. The hospital in Cesky Krumlov, the construction of which began in 1909, was built in 1911 as the 'Nemocnice Císaře Františka Josefa I.' As the time went by, new buildings were built up. The hospital was renamed to 'Všeobecná veřejná nemocnice' in 1942. In the following years the hospital expanded until the current condition. Water quality and presence of Legionella is a world-wide issue, which we must fight against. The thesis is divided into two parts. First, theoretical part, which includes both general and specific knowledge about Legionella, its health risks, the environment in which it occurs, possibilities of eliminating, suitability of the material for hot water pipes, gained in professional literature and a part of the Czech legislation dealing with public health protection, the law 'No. 258/2004 Coll.' in actual version and quality of drinking water and hot water. In the second, empirical part, I focus on the situation of the hospital in Cesky Krumlov from 2009 till 2015, concerning newly built boiler room and the whole distribution system of hot water regarding Legionella. Particularly I focused on materials used for ecologisation of the gas boiler room and materials used for hot water pipes and actual state of water distribution in individual buildings of this health care facility. I mentioned the analysis of the water samples performed by an accredited laboratory with corresponding technical documentation, which concerns the water distribution system, provided by the medical facility. I used secondary data analysis to evaluate these documents. Regarding the results from 2009 to 2015 the microbiological quality of warm water doesn't meet the limits defined in the Attachment No. 3 of the above mentioned law Order 252/2004 Coll. Limit value for colony forming units of Legionella is set to maximum of 100 CFU. In most of the samples this limit was exceeded by series of units up to hundred thousands of units. The last results in 2015 prove improvement of the unfavorable situation. In that year the analysis was tested three times. First in February, where the CFU units were 'only' in hundreds, with the top value of 550 CFU in the Postacute Care ward. Second analysis was performed in June that same year. Results were acceptable. The highest value was 64 CFU. Last analysis in the hospital was performed in December. Increased concentration of Legionella was again in the Surgery building. There were established of 1400 colony forming units. There were 300 CFU in the Postacute Care ward and the limit value of 100 CFU was in the ward of Internal medicine. The answers to research questions 'How to prevent reproduction of Legionella peumophylis in the water distribution system of the hospital in Cesky Krumlov?' and 'How to ensure a sufficient amount of quality hot water in the medical facility?' are included at the end of the stated recommendations. A risk factor causing the fast reproduction of Legionella is the old water distribution system in most of the buildings and low water temperature of water leaving the boiler, which is 55°C. All mentioned results and evaluations are included in this thesis as well as attached pictures, which show the environment and situation within the Health Care Institutions.

Nové postupy biomonitoringu cizorodých látek ve vodním prostředí
ČERVENÝ, Daniel
Within the presented work, several approaches of biomonitoring were studied. A well-established method for human health risk assessment was applied to evaluate the quality of fish from open waters in the Czech Republic. As this work is targeted on sport fishermen, who frequently consume their own catches, besides the publication in scientific journal, a brochure with results of this study was distributed via the Czech Fishing Union. Health risks for consumers related to the consumption of wild fish were found strongly species and locality dependent. As there is no risks related with the consumption of carp (Cyprinus carpio) at all investigated sites, frequent consumption of predatory fish should be avoided at some fishing grounds. The use of passive samplers has become more and more attractive in the last two decades. As these devices are able to mimic the biological uptake of chemicals, their potential for replacing fish as bioindicators in routine biomonitoring programmes is evident. In our study, the comparison between analysis of fish tissues and POCIS extracts from selected sampling sites confirms this idea about interchangeability of these indicators in the case of PFASs as target pollutants. Moreover, no metabolic transformation of contaminants present in water take place in passive samplers contrary to living organisms, thus these reflect the actual contamination at the locality more precisely. The use of passive samplers completely fulfils the internationally accepted principles of Replacement, Reduction, Refinement (the three R´s). Another promising approach using YOY fish as bioindicators was evaluated within the present study. Multispecies samples of YOY fish homogenate was found as a better indicator for wide range of pollutants than muscle tissue of adult fish within one species from the same locality. As all inner organs and tissues are presented in analysed samples, more target pollutants in higher concentrations are detected compared to the muscle of adults. Besides the higher sensitivity in pollutants detection and quantification, practical and economic benefits are of concern in the case of the YOY fish approach. The YOY fish approach also particularly fulfil the three R´s strategy, as sampling of this age group of fish has a smaller impact on the environment than the sampling of adults. In case of mercury, that was found as a limiting contaminant for the consumption of fish from open waters in the Czech Republic, a nonlethal method of finclips sampling can be used for the monitoring of this compound in aquatic environments. Besides the monitoring, our optimised method for the estimation of muscle tissue concentrations could be used for human health risk assessment as well. The difference between real muscle concentrations and concentrations estimated using our method differs less than 10% in most of the investigated localities. Benthic organisms are an important part of the food web in aquatic environments, but insufficient information about its contamination is available. In another study included in this thesis, first evidence about bioaccumulation of certain pharmaceuticals in benthic organisms was described. Although, pharmaceuticals are generally considered to be not accumulative in organisms, our study proved that certain pharmaceuticals have bioaccumulation potential. From this finding, it is evident that not only the concentrations of pharmaceutical dissolved in water but also the diet represents an important exposure pathway of contamination by these compounds for organisms (fish) inhabiting aquatic environments.

Elitism in nursing
KUČEROVÁ, Kateřina
The topic ``Elitism in nursing{\crqq} was chosen based on the author´s interest in this issue, which is considered very attractive, and tributary to the present time, when nursing in our country is undergoing a revolutionary change. Nurses gain new competences and become partners of physicians, new legislature related to the profession comes into effect continuously, there is an effort to enhance the prestige of nurses and thereby to increase their status in the eyes of both the medical and general public. As mentioned above, the entire field of nursing, the nursing education system and the nursing profession in our country has been undergoing a fundamental transformation for some time, which places high demands on information, lifelong learning, free access to the latest information on the course of events not only in our country but especially on the international professional scene. Nursing is a field that has multiple layers - from basic nursing care, which is within the competence of nurses, to a specialized nursing and superspecialized care, which requires thanks to advances in nursing science the highest possible level of education. To define the elite of the nursing profession, it is necessary to specify the elite as an exclusive social group. Through this study the author tried to describe the issue of elitism in nursing in a comprehensive form. The objective was to briefly characterize the current situation in terms of the relationship between different groups of nurses and also debate over the question: "What does it take to be a nurse?" Is it the knowledge of an intricate technique or empathic wiping sweat from a patient´s forehead? The new century makes the nurse think about the concept of extended roles in nursing, which should help elevate social status of the profession. A negative feature is that a nurse has been detracted from the kind of work for which she had become a nurse - the nursing care of a patient and the care of basic biological needs of a patient. Due to this aspect, a lot of nurses believe that enhancing the prestige of the nursing profession is not compatible with the term ``menial{\crqq} job relating to nursing. The research outcomes showed that in Czech nursing, there is a status called elitism, and that there are disciplines perceived as exclusive, the relationship between professionalization and elitism was also proved. The research survey noted a big shift in improving communication between nurses and patients compared to the past years, and the author hopes that also a better communication between nurses will contribute to the improvement of relations on both sides, both the exclusive and the so-called common, because a truly elite - exceptional nurse is the one who combines education with a good character.
