Polymeric blends of thermoplastic starch with other biodegradable polymers
Nováková, Pavlína ; Petruš, Josef (referee) ; Kučera, František (advisor)
The master's thesis deals with the preparation and properties of biodegradable polymer blends of thermoplastic starch (TPS) with polyhydroxybutyrate (PHB) with emphasis on the compatibilization of the immiscible polymer blend. The theoretical part focuses on the characterization of thermoplastic starch, thermodynamics of polymer blends, possible ways of compatibilization of polymer blends and a summary of the current knowledge on polymer blends of thermoplastic starch with biodegradable polymers. The experimental part deals with the modification of starch and PHB with maleic anhydride in order to compatibilize the polymer blend. The binding of the monomer to the polymers was confirmed by infrared spectroscopy and acid-base titration. Subsequently, using the prepared modified polymers, TPS/PHB blends were prepared and the effect of compatibilization and blend composition on the properties was evaluated. Differential scanning calorimetry (DSC) was used to observe the melting and crystallization process, the changes in molecular weight of the polymers were assessed by determining the melt flow index. Tensile strength, elongation at break and the effect of ageing on the mentioned mechanical properties were determined by tensile testing, morphology was observed by electron microscopy (SEM).

The effect of microfluidic sperm separation on the success of IVF therapy
NOVÁKOVÁ, Pavla
More and more couples are coming to assisted reproduction centres to solve conception problems. Despite initial efforts to improve lifestyle and reduce daily stress, problems in conceiving and delivering a healthy baby can be caused by one or a combination of multiple factors, and in such cases infertile couples opt for assisted reproductive treatment. In earlier times, the focus in the field of reproductive medicine was mainly on female fertility. In recent years, assisted reproductive medicine has largely focused on the field of andrology. In this regard, the development of enhanced spermiogram methods and sperm processing techniques has been developed. The current trend in reproductive embryology and andrology methods is to mimic the in vivo environment as much as possible. The aim of this bachelor's thesis was to determine whether the method of microfluidic sperm separation has an effect on sperm quality and whether the use of sperm obtained in this way influences the success of IVF treatment. In order to achieve the objectives of this study, data from 129 couples who underwent treatment in our IVF centre by donated oocytes and at the same time sperm from fresh ejaculate were used. The sperm samples were divided into two groups, namely for processing by gradient centrifugation and separation by microfluidic chip. The sperm were then used for in vitro fertilization using intracytoplasmic sperm injection method. Cycles with donated oocytes were selected to minimize the influence of female factor. The results of this work indicate that sperm processing by microfluidic chip method has a positive impact on the success of IVF treatment.

Need of intimacy of patients women 65+
NOVÁKOVÁ, Pavlína
The aim of this bachelor's thesis was to determine the status of the needs for intimacy and privacy of elderly women aged 65+ in a nursing home. Elderly women lose part of their privacy by entering such a facility. According to their degree of dependence on care, their intimate zone is violated during nursing care. I used the method of non-standardized interviews and direct covert participant observation to find out how the elderly women feel and cope in such situations. I collected data from 10 female clients and 4 members of the nursing staff of the Stachy-Kusov Nursing Home. The group of female clients was deliberately selected to represent seniors of different levels of self-care, mobility and care dependency. All nursing professions were represented among the staff. In the interviews, I explored how the clients felt in situations where they had to surrender some of their privacy and intimacy, how they coped with these feelings, and asked about their willingness and ability to communicate these topics. I investigated how nursing staff perceived these facts, their ability to empathize and communicate non-verbally with the elderly women in their care. From the data obtained, I drew conclusions regarding the saturation of the seniors' need for intimacy. It shows that individual approach with kindness and consideration is important to improve the feelings of care recipients. It is always necessary to act in the interest of preserving the dignity of the clients, to leave them the right to make decisions for themselves, not to reduce their capacity for self-care and to offer the possibility of relaxation through positive experiences or activities. In my research, the insufficient number of direct care workers to meet the individual needs of clients and the related lack of time that can be devoted to each client proved to be the limiting factor.

Aquaria Production Bukovany
Nováková, Pavla ; Štikar, Jaroslav (referee) ; Nový, Alois (advisor) ; Donaťáková, Dagmar (advisor)
The bachelor’s thesis is based on an architectural study worked up in the fourth semester of the bachelor’s study during the subject Ateliér architektonické tvorby III – AG033. The aim of the subject was the design of an industrial object designed for the production of aquaria on an assigned parcel in the village Bukovany near Kyjov. Not only was there a need for the design of production areas, but it was also necessary to design areas for the production of related furniture, an administrative area and a showroom for the presentation of products. The objective of the thesis was the creation of a construction study, the documentation for the execution of the project and an architectonic detail for the designed building. The assigned parcel is located on the edge of the village of Bukovany, in a relatively calm part of the village surrounded by a football field, cemetery and a former agricultural area. The designed object is formed of 6 separated areas – an administrative area, an exhibition and entry area, a production area, a woodworking area, a storage area and a technical area. The building is formed of a ground floor and one underground floor. Structurally the building is designed on a 6-meter module and the mixed structural system is used. For lighting the areas continuous saddle skylights are used, which switch to vertical elements on the edges of the building. The surroundings of the building are landscaped, including a resting area with a small lake on the southern part of the parcel.

Sports and Relaxation Centre Za Lužánkami, Brno
Nováková, Pavla ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
The diploma thesis is based on a design of a sports recreational centre in Brno za Lužánkami. The area has a very rich sports history (former football stadium, ice arena, swimming pool,…), with great importance for the city of Brno and its residents. Due to the decay and bad technical condition of the structures, sports activity Za Lužánkami was suppressed at the end of the last century, and its return to the location is very current. The goal of the thesis was a design for the utilization of the area for various uses with a preference for leisure sports activities and offering options for all age groups during the entire year. In the first stage, an urban-architectural study was compiled, including a new functional use of the area for recreational sporting and relaxation, while being better connected with the surrounding localities. Following that, a complex architectural study of a multipurpose hall was designed in place of the former football stadium. The hall offers various possibilities for recreational sports, children‘s club training, talks and exhibitions hosting. Included are corresponding sanitary facilities, technical facilities, underground parking, commercial areas and a cafe. The structure is set in the ground and thanks to the variable roof inclination the rooftop park is directly accessible from the ground. The roof access is proposed from four places and offers further relaxation spots around the entire roof area.
