Development of cereal products for specifc nutrition with addition of fruits and vegetables
Růžičková, Magdalena ; Kubalová, Michaela (referee) ; Bendová, Agáta (advisor)
This bachelor thesis focuses on developing gluten-free cereal products for special nutrition. The main focus is on increasing the concentration of phenolic compounds and antioxidants in cereals by adding fruit and vegetable components. The theoretical part includes findings from professional literature on cereals, gluten-free cereals and their chemical composition. A chapter devoted to celiac disease and gluten-free diet was also included. Furthermore, the theoretical part focuses on possible methods of enrichment and also on selected fruits and vegetables used in the experimental part. In the experimental part, five samples of gluten-free cereals were analysed, namely black, red, brown and white rice and corn. The concentration of flavonoids, polyphenols, antioxidants, carbohydrates, proteins, -carotenes, anthocyanins, gluten, -glucans, fatty acids and lipophilic vitamins was determined in the cereal samples. Selected samples were also tested for antimicrobial activity. The black rice sample showed the best results in the majority of the measurements. Selected samples of eight types of fruit (cranberry, raspberry, strawberry, blueberry, blackcurrant, mango, banana, kiwi) and four types of vegetables (broccoli, carrot, green pea, beetroot) were also analysed. The concentration of flavonoids, polyphenols, antioxidants, carotenes, anthocyanins, ascorbic acid and lipophilic vitamins was determined in these samples. Antimicrobial tests were performed on selected fruit and vegetable samples Among the fruit samples, the best results in the majority of measurements were in blueberry and blackcurrant samples. Among the vegetable samples, the best results were obtained from the beetroot sample. From the best cereal, fruit and vegetable samples were created porridges as a final product. In these samples, the concentration of polyphenols and antioxidants was determined. The highest concentration of both compounds was found in the porridge with black rice and blueberry.

Rehabilitation nursing at the surgical department
RŮŽIČKOVÁ, Monika
This diploma thesis deals with the problem of rehabilitation nursing in surgical wards. The aim of the research was to find out whether nurses are perceived as part of a multidisciplinary team for rehabilitation care, also to what extent the documentation of rehabilitation care is effective, finally the investigation involved the patients experiences of the nurses involvement in rehabilitation care. The empirical part of the thesis was conducted using quantitative and qualitative methods. The quantitative method data collection was carried out using a standardized questionnaire consisting of seventeen questions for nurse practitioners, general nurses and nurses with a masters degree, from selected surgical wards. For the qualitative method, semi-structured interview technique was chosen and was conducted with patients from trauma and orthopedic intensive care units. Information from the interviews were coded and four categories were based on the analysis. The interviews were analyzed using the "pencil and paper method". The selection of informants was deliberate. The informants were from the Hospital České Budějovice within a maximum period after surgery being fourteen. The results of the quantitative research showed that there were communication gaps in the multidisciplinary team. Thus, the possible risk of errors by staff is increased, where patients may be harmed. Another bit of findings, based on the documentation, showed that nurses perceive the implementation of rehabilitation interventions as more of an evidence of improvement in the patient's condition than as unnecessary workload. Furthermore, as is statistically demonstrated in the third hypothesis, we found that nurses provide rehabilitation treatment based on the input of other health care professionals rather than from their own initiative. In the questionnaire survey, nurses most frequently reported that their physician encouraged them to provide rehabilitation treatment. In the qualitative research part of the thesis, we mapped patients' experiences with nurses' involvement in rehabilitation treatment. The interview revealed that the informants had difficulty distinguishing between the terms rehabilitation treatment and physiotherapy. What we also learned was that most informants are satisfied with the communication between them and the nurse staff, which is necessary in promoting self-sufficiency. The interview also showed that none of the patients were educated in the preoperative period and about self-sufficiency training or verticalization. Another insufficiency, which was found through the research was in the area of education about respiratory rehabilitation, where informants showed gaps in information about prevention of complications. The informants had positive responses in the area of pain reduction in rehabilitation treatment. It is evident from the responses that nurses pay attention to analgesic treatment of patients during rehabilitation treatment. Finally, we asked informants about compensatory aids. As a result, informants from orthopedic wards were better informed about compensatory aids than informants from trauma wards. This is probably due to longer preoperative preparation. Through the analysis of the empirical part of the thesis, it is obvious that although the nursing care in the selected wards is of a high standard, there are obvious deficiencies in rehabilitation care. Therefore, the results could be helpful in order to focus on the problems in rehabilitation care. This could help facilitate the actions of management and medical staff in the selected surgical wards to improve the quality of nursing care.

UNIVERSAL BASIC OPRESSION
Růžičková, Martina ; Jánoščík,, Václav (referee) ; Sterec, Pavel (advisor)
Master's thesis Polyamory Design Unit (PDU) explores the possibilities of collaboration between experts being active in fine arts, product design, graphic design, architecture and philosophy in order to create a speculative future scenario. Together with Jana Trundova, Simon Barak, Ondrej Mohyla and Lukas Likavcan, I create the concept and the presentation structure for a housing complex, which is designed for polyamoric coexistence of human and non-human entities. Such a coexistence is made possible by full automation of work and global implementation of universal basic income. These initial parameters constitute a big emancipatory potential, that could change present meaning of the concept of polyamory and thus redefine networks of relations in bigger scales too.

Demchenko, Hanna ; Růžičková, Miroslava (referee) ; Shatyrko,, Andriy (referee) ; Diblík, Josef (advisor)
Dizertační práce se zabývá procesy, které jsou řízeny systémy zpožděných diferenciálních rovnic $$x'(t) =f(t,x_t,u),\,\,\,\, t\ge t_{0}$$ kde $t_0 \in \mathbb{R}$, funkce $f$ je definována v jistém podprostoru množiny $[t_0,\infty)\times {C}_{\tau}^{m}\times {\mathbb{R}}^r$, $m,r \in \mathbb{N}$, ${C}_{\tau}^{m}=C([-\tau,0],{\mathbb{R}}^{m})$, $\tau>0$, $x_t(\theta):=x(t+\theta)$, $\theta\in[-\tau,0]$, $x\colon [t_0-\tau,\infty)\to \mathbb{R}^{m}$. Za předpokladu $f(t,\theta_m^*,\theta_r)=\theta_m$, kde ${\theta}_m^*\in {C}_{\tau}^{m}$ je nulová vektorová funkce, $\theta_r$ a $\theta_m$ jsou $r$ a $m$-dimenzionální nulové vektory, je říd\'{i}cí funkce $u=u(t,x_t)$, $u\colon[t_0,\infty)\times {C}_{\tau}^{m}\to \mathbb{R}^{r}$, $u(t,{\theta}_m^*)=\theta_r$ určena tak, že nulové řešení $x(t)=\theta_m$, $t\ge t_{0}-\tau$ systému je asymptoticky stabilní a pro libovolné řešení $x=x(t)$ integrál $$\int _{t_{0}}^{\infty}\omega \left(t,x_t,u(t,x_t)\right)\diff t,$$ kde $\omega$ je pozitivně definitní funkcionál, existuje a nabývá své minimální hodnoty v daném smyslu. Pro řešení tohoto problému byla Malkinova metoda pro obyčejné diferenciální systémy rozšířena na zpožděné funkcionální diferenciální rovnice a byla použita druhá metoda Lyapunova. Výsledky jsou ilustrovány příklady a aplikovány na některé třídy zpožděných lineárních diferenciálních rovnic.

Morávková, Blanka ; Růžičková, Miroslava (referee) ; Khusainov, Denys (referee) ; Diblík, Josef (advisor)
Disertační práce se zabývá lineárními diskrétními systémy s konstantními maticemi a s jedním nebo dvěma zpožděními. Hlavním cílem je odvodit vzorce analyticky popisující řešení počátečních úloh. K tomu jsou definovány speciální maticové funkce zvané diskrétní maticové zpožděné exponenciály a je dokázána jejich základní vlastnost. Tyto speciální maticové funkce jsou základem analytických vzorců reprezentujících řešení počáteční úlohy. Nejprve je uvažována počáteční úloha s impulsy, které působí na řešení v některých předepsaných bodech, a jsou odvozeny vzorce popisující řešení této úlohy. V další části disertační práce jsou definovány dvě různé diskrétní maticové zpožděné exponenciály pro dvě zpoždění a jsou dokázány jejich základní vlastnosti. Tyto diskrétní maticové zpožděné exponenciály nám dávají možnost najít reprezentaci řešení lineárních systémů se dvěma zpožděními. Tato řešení jsou konstruována v poslední kapitole disertační práce, kde je řešení tohoto problému dáno pomocí dvou různých vzorců.

Existence and Properties of Global Solutions of Mixed-Type Functional Differential Equations
Vážanová, Gabriela ; Růžičková, Miroslava (referee) ; Fečkan,, Michal (referee) ; Diblík, Josef (advisor)
Dizertační práce se věnuje funkcionálním diferenciálním rovnicím smíšeného typu. Poskytuje kritéria pro existenci globálních a semi-globálních řešení diferenciálních systémů smíšeného typu. Metody použité v teto práci spočívají v sestavení vhodných operátorů pro diferenciální rovnice a prokázání existence jejich pevných bodů. Tyto pevné body jsou potom použity ke konstrukci řešení rovnic s předcházením a zpožděním. V důkazech tvrzení jsou použity monotónní iterační metoda a Schauderovy-Tychonovovy věty o existenci pevného bodu. V obou případech jsou uvedeny také odhady řešení. Pokud je použita iterační metoda, lze tyto odhady zlepšit iterováním. Kromě toho jsou odvozena kritéria pro lineární rovnice a systémy a je uvedena řada přikladů. Dosažené výsledky lze aplikovat také pro obyčejné diferenciální rovnice nebo diferenciální rovnice se zpožděním či s předcházením argumentu.

Weakly Delayed Systems of Linear Discrete Equations in R^3
Šafařík, Jan ; Khusainov, Denys (referee) ; Růžičková, Miroslava (referee) ; Diblík, Josef (advisor)
Dizertační práce se zabývá konstrukcí obecného řešení slabě zpožděných systémů lineárních diskrétních rovnic v ${\mathbb R}^3$ tvaru \begin{equation*} x(k+1)=Ax(k)+Bx(k-m), \end{equation*} kde $m>0$ je kladné celé číslo, $x\colon \bZ_{-m}^{\infty}\to\bR^3$, $\bZ_{-m}^{\infty} := \{-m, -m+1, \dots, \infty\}$, $k\in\bZ_0^{\infty}$, $A=(a_{ij})$ a $B=(b_{ij})$ jsou konstantní $3\times 3$ matice. Charakteristické rovnice těchto systémů jsou identické s charakteristickými rovnicemi systému, který neobsahuje zpožděné členy. Jsou získána kriteria garantující, že daný systém je slabě zpožděný a následně jsou tato kritéria specifikována pro všechny možné případy Jordanova tvaru matice $A$. Systém je vyřešen pomocí metody, která ho transformuje na systém vyšší dimenze, ale bez zpoždění \begin{equation*} y(k+1)=\mathcal{A}y(k), \end{equation*} kde ${\mathrm{dim}}\ y = 3(m+1)$. Pomocí metod lineární algebry je možné najít Jordanovy formy matice $\mathcal{A}$ v závislosti na vlastních číslech matic $A$ and $B$. Tudíž lze nalézt obecné řešení nového systému a v důsledku toho pak odvodit obecné řešení počátečního systému.
