Statistical Analysis of Air Pollution by Selected Pollutants
Pernicová, Veronika ; Durnová, Markéta (referee) ; Balgová, Zuzana (advisor)
This thesis analyses an occurrence of detected pollutant concentrations of nitrogen oxides, dust particles of the size od 10 and 2,5 m and ground ozone in years 2015-2019 in seven chosen locations in Brno agglomeration. In the introduction, the thesis describes basic terms, the issues of air pollution and relevant legislation. Individual pollutants are defined and also their effect on environment and human health. After that, the locations of Brno, for which the analysis is made, is specified. The dynamics of development of individual pollutants is shown through a statistical analysis of individual time lines. The analysis also focuses on the difference in the level of pollution during weekdays, holidays, seasons or rush hour. The quantities are also viewed from the point of view of the relevant air pollution limits and the influence of climatic factors, which significantly affect their concentrations.

The Synthesis and Characterisation of Biocomposite Materials for Potential Application in Medicine
Balgová, Zuzana ; Plešingerová,, Beatrice (referee) ; Bakoš, Dušan (referee) ; Palou, Martin (advisor)
Dizertační práce se zabývala syntézou a studiem kompozitních materiálů pro potenciální lékařské využití. Teoretická část je zaměřena na biomateriály, zejména na kompozity složené z polyvinylalkoholu a hydroxyapatitu(PVA/HA). Byly připraveny kompozitní membrány složené z polyvinylalkoholu s různým hmotnostním zastoupením hydroxyapatitu - 0%, 10%, 20%, 30%, 40% a 50%. Hydroxyapatit (HA) byl připraven srážecí metodou z hydrogenfosforečnanu amonného a tetrahydrátu dusičnanu vápenatého ve vodném alkalickém prostředí. Vzniklá suspenze se smísila s roztokem polyvinylalkoholu, který byl připraven rozpuštěním ve vodě o teplotě 85° C. Jednotlivé směsi byly odlity do formy a sušeny po dobu 7 dní při teplotě 30 ° C, vzniklé 0,5 mm tenké membrány byly analyzovány ATR-FTIR spektroskopií k identifikaci funkčních skupin v kompozitu, dále byla provedena XRD analýza. Zkouška tahem a TGA měření byly realizovány k určení vlivu HA na mechanické vlastnosti, respektive změnu tepelné odolnosti kompozitů ve srovnání s čistým PVA. Byla provedena zkouška bioaktivity v simulovaném krevním roztoku (SBF) po dobu 2h, 7 a 28 dnů. SEM byla použita k charakterizaci povrchové mikrostruktury biocompositních membrán před a po ponoření do SBF. Na povrchu testovaných membrán vznikla vrstva apatitu, která je charakteristická pro bioaktivní materiály. Bylo zjištěno, že s rostoucím množstvím HA částic docházelo ke vzniku aglomerátů v kompozitu, které vznikly mimo jiné jako důsledek růstu krystalů HA během sušení membrán. Bioaktivita rostla s delším působením SBF na vzorky.

Analysis, assessment and management of risks of manufacturing process
Ďurovcová, Júlia ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This thesis focuses on risk management in the production process of Frentech Aerospace, s.r.o. At the beginning the thesis covers the theoretical background of risk management, quality management and safety. This knowledge has been expanded with quality and safety requirements based on international standards. For a proper measurement of the identified hazards, a perfect understanding of the evaluated system is necessary. For this reason, the method of process flow diagrams was used to provide a visual representation of the company's production process, together with a description of the individual production operations. The FTA method was selected to identify the causes of the failure conditions, which provided the basis for the final failure mode and consequence analysis. Due to the systematic approach of risk identification and assessment, the most serious process risks were selected. These are provided in the thesis with recommended preventive suggestions that lead to the minimization of the identified risks.

Analysis, assessment and management of risks of the purchasing process of the selected company
Šurík, Jakub ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This diploma thesis is focused on the analysis of the purchasing process of a selected company. The purchasing process in the company is approached theoretically, including various definitions from the field of riskology. After establishing the objectives of the thesis, the specific purchasing process of the selected company is analyzed using BPMN diagrams to visualize it. The PESTLE method is used to analyze the environment of the company. A register of possible risks in the purchasing process of the company is written to create a risk matrix. Subsequent bow-tie analysis provides a more detailed elaboration of the risks and proposes preventive and reactive measures to reduce the mentioned risks. This is followed by a summary of the analysis results obtained and an evaluation of the benefits of the proposed measures.

Analysis, assessment and management of risks of process
Kaplan, Miloslav ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This master’s thesis deals with risk management associated with a construction company. The main goal is to analyze possible risks, asses their magnitude, and propose measures that mitigate the overall risk. For construction companies, it is crucial to mitigate risk, especially from the point of view of safety, but attention must also be paid to the quality of contracts, their timely fulfilment, and the overall profitability of the company. The evaluation of these important attributes is processed using FMEA analysis, and one selected risk is displayed graphically using the Bow tie method. The result is the analysis of possible risks for the internal and external aspects of the company as well as for interested parties with the design of countermeasures to reduce the level of risk. The partial goal of the work is to assess whether the company complies with all legislative regulations. This is processed through the assessment of compliance with legislation.

Risk Analysis of Sample Preparation for Transmission Electron Microscopy
Gálíková, Markéta ; Hrabová, Kristýna (referee) ; Balgová, Zuzana (advisor)
Tato diplomová práce prezentuje analýzu rizik při přípravě vzorků pro transmisní elektronovou mikrosopii. Jejím cílem je zvýšit bezpečnost práce v laboratořích, které se přípravou a nalýzou vzorků zabývají. Tato práce se zaměřuje na identifikaci potenciálních nebezpečí, hodnocení rizik a navrhuje efektivní strategie na zmírnění nebo eliminaci rizik. Práce je rozdělena na dvě hlavní části. První je teoretická, která shrnuje informace o přípravě vzorků a legislativní požadavky určené Evrpskou únií a Českou republikou. Druhá, praktická část, popisuje vypracovanou analýzu rizik. Blokový diagram, analýza příčin vad a následků i analýza příčin a následků byly použity tak, aby se zjistilo co nejvíce informací o rizicích spojených s procesem přípravy vzorků. Navíc byla navrhnuta opatření tak, aby byla zjištěná rizika eliminována nebo alespoň zmírněna. Navrhovaná opatření ke zmírnění rizik byla například: používání osobních ochranných prostředků, ergonomická opatření, revize vybavení a pokyny pro zacházení s chemickými látkami. Výsledky analýzy rizik ukazují, že po zavedení navrhovaných opatření dojde k výraznému snížení úrovně rizika, což ilustruje snížení prioritního rizikového čísla. Zjištění zdůrazňují význam začlenění analýzy rizik do procesu přípravy vzorků pro vytvoření bezpečnějšího pracovního prostředí.
