Horký, Matouš ; Baláš, Jiří (advisor) ; Turčová, Ivana (referee)
Objective: The aim of the work was to analyze how different types of natural environments affect the physical and mental health of individuals. Methods: 7 students of UK FTVS participated in the research. The participants visited the natural environment (blue area) in Prague's Troja and the laboratory in the UK FTVS building. While visiting these environments, they underwent: a 10-minute Stroop test to induce cognitive stress and 40 minutes of walking at a chosen pace. Current mental states and emotions were monitored using the standardized POMS (Profile of Mood State) questionnaire, which was filled in a total of four times during the visit. Results: From the average results of the POMS questionnaire (on a scale of 0-4, 0= not at all, 4= very much), it was obtained that the degree of anger in the laboratory environment was 0.68 and in the blue environment 0.39. Fatigue level 1.17 in lab and 1.19 in water. Depression values in the laboratory 0.67 and in water 0.54. Confusion was 0.88 in the lab versus 0.55 in the blue environment. Voltage in the lab 1.02 and in the blue environment 0.60. Vitality in the aquatic environment 1.51 and in the laboratory 1.29. The average values of individual POMS dimensions over time were (blue space) after the initial measurement: anger 0.40, fatigue 0.95, depression...

Micromobility in Brno
Honl, Tomáš ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The focus of the bachelor thesis is passenger transport and the related micromobility. Especially in large cities it is possible to use the so-called Shared Transport, i.e. one where a means of transport is rented only for the time needed for transport, after which it is immediately available to other users. Therefore, the first part will be devoted to the introduction of the different means, both conventional and shared. In parallel, some of the advantages and pitfalls of the different transport methods will also be outlined. In the second part, representatives of each category will be put to the test on predetermined routes to see if and how their use can be beneficial. The comparisons will include price and speed of transport. The result will then be an evaluation of each means of transport.

Optimization of Circadian Rhythms and Sleep Patterns
Zídková, Tereza ; Ehler, Edvard (advisor) ; Nejedlý, Adam (referee)
Optimization of circadian rhythms and sleep patterns The abstract of the bachelor thesis This bachelor thesis summarizes current scientific knowledge on the relationships between circadian rhythms, sleep, and light, and analyzes their mutual interactions influencing the health of organisms, particularly human society. Sleep is among the most crucial determinants of overall health, and the influence of natural or artifficial light can effectively optimize it on one hand, but desynchronize it to the detriment of overall organism functioning on the other. Modern humans are increasingly exposed to artifficial lighting due to spending the majority of their time indoors, leading to a deficiency in natural light globally. This is associated with numerous problems ranging from disruptions in biological rhythms to various other civilization-related illnesses. In summarizing this issue, some recommendations are made for optimizing and personalizing both artificial and natural sunlight to improve sleep, which is a significant biological marker for optimal health.

The effect of the circadian rhythm on the work of a paramedic
ŠEDIVÝ, Martin
The topic of the bachelor's thesis is "The effect of the circadian rhythm on the work of a paramedic". Most rescuers may not even realize the great sacrifice they make by performing this demanding profession. This is a very respectable job, which is burdened with a huge amount of stress and a demanding work schedule. The combination of these two unfavorable factors may have a negative impact on the health of rescuers over a longer period of time. The theoretical part deals with the explanation of the term circadian rhythm, sleep and its structure, nutrition, physical activities, blue light, caffeine, health complications that are the result of a disturbed circadian rhythm and the effect of circadian rhythmicity on work efficiency. The research part was implemented using semi-structured interviews, and 12 informants who are employed at the South Bohemian Region Medical Rescue Service in the position of paramedic were included in the research investigation. Each informant was asked the same questions, which were then evaluated using the coding technique and were divided into several categories and subcategories. The main topics for responding the objective of the work were health complications of shift work, adaptation to shift work, principles of proper nutrition and sleeping habits. Research has shown that the circadian rhythm affects the work of a paramedic, but it is very individual and affects each paramedic in a different way. Alternating irregular shifts are difficult to get used to, and working at night is not ideal from a physiological point of view. Most of the rescuers confirmed to us that they had a lower work performance and a longer reaction time during the night hours. Furthermore, night shifts have a negative effect on the health of workers, and health complications may occur years later, which may not allow rescuers to continue to perform their work as well as before.

Autocentre VW group Brno
Hejcman, Josef ; Bílek, Zdeněk (referee) ; Dýr, Petr (advisor)
The subject of the bachelor thesis is the design of a car center for the VW Group in Brno. The car center includes a showroom with the sale of new cars from the brands VW, Seat, Škoda, and Audi, a spare parts shop, and a service center. The site under consideration is located in the Brno – Komárov district, between Sokolova and Hněvkovského streets. There is a planned construction of a road from Sokolova Street on the site, dividing it into two parts, with the car center situated in the larger part along Hněvkovského Street. The new road will provide access to the facility for vehicles. The proposed car center is a standalone two-story building consisting of two prismatic-shaped volumes connected to each other with a trapezoidal footprint. It is a structure with two halls made of a steel skeletal system with a reinforced concrete core between them. The halls are differentiated in terms of height, function, and color. The roof is green (vegetative) and equipped with solar panels. The showroom for the sale of new cars and the spare parts shop are located in the taller hall, which features a prominently glazed column-truss facade. This facade is followed by a Dri Design Tapered cassette system in a dark blue color (RAL 5026) at the level of the roof's supporting structure. The service area with a warehouse is situated in the smaller, more expansive hall, and its facade consists of vertically laid sandwich panels with a smooth surface in a light color (RAL 9016), and horizontally laid sandwich panels in the color RAL 5026 in columns around the doors and windows. The halls thus contrast with each other. The hygiene facilities for employees are located in the reinforced concrete core.

An apartment building with student dormitories on Peace Square in Brno
Vašková, Kateřina ; Klimecký, Martin (referee) ; Gerö, Jiří (advisor)
The subject of my bachelor's thesis focuses on the concept of a residential building and student dormitories in the urban district of Brno – Stránice. The studied area is situated in close proximity to Kraví Hory. The northwest boundary of the plot also represents the outskirts of Náměstí Míru. The southwest part of the plot adjoins existing student dormitories, while the southeast boundary connects to a local road, Cyril and Methodius gymnasium, and a secondary vocational school for pedagogy. The surroundings efficiently connect to urban transportation infrastructure, and in terms of automobile traffic, the area is linked to several main roads, with direct access from the north to the main road Údolní and further to the adjacent Lerchova Street. The proposed complex consists of a residential building and student dormitories. This work specifically addresses one of the two blocks of student dormitories, a four-story building with one underground floor. In the underground floor, there are garages and a technical room. The top of the building is terminated by a flat green roof. The construction is designed using a system of ceramic masonry, Porotherm, insulated with mineral wool. The ceilings are predominantly designed systematically, using the MIAKO ceiling system, with the exception of the ceiling above the basement. Each floor offers six dormitory rooms for two to three students, and from the second floor upwards, some rooms are supplemented with comfortable balconies. These rooms include a kitchen, bathroom and a living area. End rooms are specially designed for individuals with reduced mobility. Each floor's corridor provides space for communication, reading, or phone calls, thanks to the presence of seating furniture. The basement serves as garages and also houses a technical room. The building's facade is designed as plastered, complemented by window frames antracid coloured and railings in turquoise, contributing to young appearance of the entire structure.

Golden nanosystems for molecular detection of biological samples using Surface-Enhanced Raman Spectroscopy
Kebabová, Mona ; Bernátová,, Silva (referee) ; Samek, Ota (advisor)
Citlivá a přesná detekce analytů nebo bakterií je klíčovým krokem při identifikaci nebezpečných sloučenin či patogenů, ať už v oblasti medicíny nebo bezpečnosti potravin. Využití pokročilých metod, jako je povrchově zesílená Ramanova spektroskopie (SERS), by pomohlo identifikovat bakterie nebo analyty s vysokou citlivostí a přesností. Tato diplomová práce zaměřuje na syntézu a charakterizaci kovových nanočástic (NČ) pro citlivou detekci bakterií pomocí SERS, přičemž NČ zvyšují Ramanův signál lokalizovanou plazmonovou rezonancí. Nejdříve jsou diskutovány nejnovější přístupy k syntéze plazmonických nanostruktur. Hlavní část experimentální práce tvoří syntéza zlatých (Au) a stříbrných (Ag) NČ, jejich charakterizace a využití pro analýzu chemických a biologických vzorků pomocí SERS. Nanočástice byly použity pro detekci molekul barviv (rhodamin 6G a methylenová modř), a patogenních bakterií Staphylococcus aureus a Escherichia coli, adsorbovaných na povrch syntetizovaných NČ. Dále byl replikován vysoce specifický sendvičový imunotest detekovatelný pomocí SERS. Tato metoda umožňuje rychlou a přesnou detekci patogenů. Na povrch nanočástic se pomocí interakce avidin-biotin vážou protilátky, které slouží k zachycení bakterií (E. coli a S. aureus). Ačkoli dílčí kroky protokolu byly úspešné, ověření funkce sendvičového imunotestu se doposud nezdařilo, pravděpodobně kvůli změnám v použitých chemikáliích a protilátkách. Kroky nezbytné k replikaci protokolu budou provedeny v budoucnu.

Transport and mechanical properties of hybrid hydrogel networks based on gellan
Sokolínský, Jan ; Pekař, Miloslav (referee) ; Kalina, Michal (advisor)
This diploma thesis deals with the characterization of the mechanical and transport properties of gellan based hybrid hydrogels. As part of this work, the process of optimizing the preparation of gellan-poly(vinylalcohol) IPN hydrogel was first studied with an emphasis on the repeatability of the preparation due to the preservation of mechanical properties of the hydrogel. Then, both on the gellan hydrogels themselves and on selected IPN compositions, the effect of various additives was studied (specifically, the effect of the addition of a plasticizer and the effect of cross-linking by polyvalent ions). Based on these tests, a set of samples was selected, on which dynamic mechanical analysis, swelling and drying experiments were additionally measured. At the end of this diploma thesis, the transport properties of selected hydrogel compositions were also studied. The tests conducted in this thesis revealed that both the formation of a dual network and the addition of the mentioned additives allow us to influence the studied properties.

Hydrogels modified by amphiphilic structures
Heger, Richard ; Sedlařík, Vladimír (referee) ; Kráčalík, Milan (referee) ; Pekař, Miloslav (advisor)
The submitted dissertation deals with the influence of amphiphilic structures on hydrogel properties. Additions of various amphiphilic substances associated with the formation of highly ordered structures affect the mechanical, transport and structural properties of hydrogels. The main inspiration for this type of work was living tissue, more precisely the extracellular matrix, which is often mimicked by hydrocolloids, and its high orderliness is responsible for its unique properties. The knowledge obtained from this tissue was applied to the hydrogel systems studied in this work. Various cross-linked hydrogel matrices (physically cross-linked agarose and gelatin, ionically cross-linked alginate and chemically cross-linked mixture of polyvinyl alcohol and chitosan) were suitable representatives for this work. These hydrogel systems were modified by the addition of various amphiphilic substances. The human body’s own phospholipid, lecithin, or variously charged more classic surfactants (CTAB, SDS and Triton X-100). Experimentally, this work is divided into three areas, the study of mechanical properties using rheology, the description of transport properties via release and flow experiments using various model drugs (rhodamine 6G, eosin B, amido black 10B, methylene blue and riboflavin), and morphological characterization using SEM. The characterization of hydrogel systems was supported by other techniques used in this work, such as drying and swelling experiments or gas sorption.
