Image processing of MRI
Němcová, Simona ; Jiřík, Radovan (referee) ; Krátká, Lucie (advisor)
This thesis deals with the cartilage imaging using magnetic resonance. At first, there is mentioned physical principle of the magnetic resonance phenomenon and the most commonly used excitation sequences, followed by the description of the 9.4 T MR imaging system Bruker BioSpec 94/30 USR, which was used for measurement in the practical part. The next part is dedicated to the composition of cartilages and describes the temporomandibular joint, due to its suitability as an object for cartilage imaging. The series of MR scans of temporomandibular joint were taken with different acquisition parameters and evaluated by program designed through the MATLAB software. The program can be used for viewing scanned images, evaluating their contrast and determining the T1 relaxation time of the tissues by creating T1 maps.

Importance of Teacher Assistant in the Inclusive Education of Romani Pupils
Němcová, Simona ; Mazáčová, Nataša (advisor) ; Kargerová, Jana (referee)
My diploma thesis deals with the role of a pedagogical assistant working mostly with gypsy children. I concentrate on the importance of this work position within our educational system with inclusive approach. The theoretical part is devoted to a wider description of a pedagogical assistant position within the current Czech educational system. The empirical part maps requirements and expectations of teachers, pupils and their legal guardians regarding pedagogical assistants and their mutual cooperation. The tools used to explore this area of interest were interviews with the pupils integrated and their legal guardians as well as a research probe carried out by teachers at primary schools. The research demonstrated that teachers really have the same expectations as those presented in professional literature. Besides that, the research revealed total absence of more spread acquaintance among legal guardians of integrated pupils. I regard this finding mentioned above beneficial. It is absolutely crucial for schools to concentrate directly on gipsy communities which both the integrated pupils and the pedagogical assistants come from, and to ensure more frequent and largely spread 'acquaintance.'

Němcová, Sára ; Lunger-Štěrbová, Daniela (advisor) ; Oulíková, Petra (referee)
The bachelor thesis called Construction activity of Václav Antonín Chotek - significant ancestral residence deals mainly with the construction activities of the V. A. Chotek and his sons in the Baroque era. The thesis is divided into two parts. The first part mentions the history of Chotek family, the fortress Bělušice and the Veltrusy Castle which both belong to the main construction activities of Count Chotek. This part also briefly describes other family residences which were maintained, built or reconstructed in Baroque period. In the second part, I want to present more specifically the residences, whose names were mentioned in the first part and which exist mainly thanks to the brothers Jan Karel and Rudolf Chotek. Therefore the second part represents a kind of catalog. All the descriptions are accompanied by pictorial documentation. I also focused here on other builders who participated in constructions or renovations. There are mentioned buildings as the castles in Chlumín and in Třebešice, the estate of Nové Dvory near Čáslav and the castle Myslibořice. Here I will also mention the House U Zlatého melounu which is located in Prague. In the final part, I would like to compare the former form of the settlements with the current one. At the end I summarize if the target from the initial part...

Pregnancy in women with assisted reproduction.
NĚMCOVÁ, Sabina
Bachelor thesis deals with pregnancy in women with assisted reproduction. The topic of the bachelor's thesis is up-to-date because every year there is an increase in the number of infertile couples and thus higher attendance of infertility centers. The bachelor thesis is divided into theoretical part and practical part. In the theoretical part we will deal with infertility in women and infertility in men. In the following chapters, we focused on assisted reproduction and assisted reproduction types. Last but not least, we will address the risks associated with assisted reproduction and ethics. The aim of the bachelor thesis is to find the attitudes of midwives to assisted reproduction. To this end, research questions have been developed: 1. How midwives perceive assisted reproduction? 2. How do midwives approach the care of a pregnant woman after assisted reproduction? The research was conducted in March and April in 2017. The qualitative research was carried out by a semi-structured interview with midwives. The interviews were conducted with nine midwives who work on a nursing unit at risk of pregnancy. Midwives were aged 27-54 years old. Respondents interviewed work in Ceske Budejovice, Prague, Ostrava and Brno. The survey was conducted with respondents on the basis of their consent to the signing "Request for Co-operation Agreement". This request to midwives guarantees anonymity and treatment of information obtained according to ethical standards. At the beginning of the interview, we obtained the respondent identification data. During the interview, respondents were asked about assisted reproduction issues. Specifically, the complications of assisted reproduction, assisted reproduction methods, midwifery attitudes to assisted reproduction and obstetricians' opinions on embryo reduction. A midwife interview led to the care of a woman with assisted reproduction and the care of women with OHSS. The opinions of midwives on the changing needs of women for assisted reproduction were also examined. The interviews were recorded on an audio device throughout. The conversations were subsequently overwritten and analyzed by the dyeing method in the text. Based on the analyzes obtained, two main categories and their sub-categories were identified. The first main category Assisted Reproduction is divided into three subcategories called Methods, Complications, and Attitudes of Midwives to the AR. The second main category is nursing care, which is divided into three subcategories called Specifics in Care of AR, Women's Awareness and Changed Needs. Midwives often encounter assisted reproduction and perceive it positively. Midwives who have personal experience with assisted reproduction perceive it better than midwives who have encountered this problem only in their practice. Midwives have found that women have altered needs after assisted reproduction, especially a sense of security and safety. The research has shown that midwives are aware of the risks associated with assisted reproduction and are partly aware of the care of women after the AR. Respondents also think that women are well informed about AR issues after assisted reproduction. A research survey has shown that each midwife is a personality and can perceive the issue of assisted reproduction differently. The result of this bachelor's thesis can be presented at expert conferences or published in professional journals.

Role of midwife in the care of pregnant woman after asisted reproduction
NĚMCOVÁ, Sabina
Bachelor thesis deals with the role of midwife in the care of a pregnant woman after assisted reproduction. The topic of assisted reproduction is nowadays very discussed, because the number of infertile couples increases, thus there is also a higher attendance of infertility centres. The bachelor thesis is divided into a theoretical part and a practical part. In the theoretical part I dealt with female infertility and male infertility. In the following chapters, I focused on assisted reproduction and its types. Last but not least, I dealt with the risks associated with assisted reproduction and its ethics. The aim of the bachelor thesis is to find out the attitudes of midwives towards assisted reproduction. To fulfil this aim, following research questions were developed: 1. How do midwives perceive assisted reproduction? 2. How do midwives approach the care for a pregnant woman after assisted reproduction? The research was conducted in March and April 2017. The qualitative research was carried out by means of semi-structured interview with midwives and unqualified public. The interviews were conducted with nine midwives who work at a nursing unit of risk pregnancy. The other respondents were four men and four women without professional education. Respondents were aged 27-54 years. Interviewed respondents work in Budweis, Prague, Ostrava and Brno. The research was conducted with respondents on the basis of their consent, by signing "Request for Co-operation Agreement". This request guarantees the midwives their anonymity and also handling the obtained information according to ethical standards. At the beginning of the interview, respondent's identification data were obtained. During the interview, respondents were asked about assisted reproduction issues. Specifically, the complications of assisted reproduction, assisted reproduction methods, midwives' attitudes to assisted reproduction and their opinions on embryo reduction. The interviews then led to the topic of care for a woman after an assisted reproduction and the care for women with OHSS. The opinions of midwives on the awareness of women and changing needs of women after assisted reproduction were also examined. The interviews were recorded on an audio device throughout their whole duration. The conversations were subsequently rewritten and analysed by the method of highlighting in the text. Based on the analyses obtained, two main categories and their sub-categories were set. The first main category Assisted reproduction was divided into three subcategories called Methods of assisted reproduction, Complications of assisted reproductions, and Attitudes of midwives towards the AR. The second main category Nursing care for a woman after AR was divided into three subcategories called Specifics in care for women after AR, Providing information for women after AR and Changed needs of women after AR.Midwives encounter assisted reproduction relatively often and perceive it positively. Midwives, who have personal experience with assisted reproduction (either by themselves, or friends, family), perceive it better than midwives who have encountered this problem only in their practice. Women who underwent AR are better acquainted with this issue than PA. On the contrary, men do not deal with assisted reproduction issues. Interviewed midwives have found out that women have altered needs after assisted reproduction, especially a sense of security and safety.. The research has shown that midwives are aware of the risks associated with assisted reproduction and are partly aware of the care for women after the AR. Respondents also think that women are well informed about AR issues after assisted reproduction.A research survey has shown that each midwife is a personality and can perceive the issue of assisted reproduction differently. Furthermore, from the research occurred, that women after AR tend more often to have complications throughout their pregnancy
