Building marketing advantage by using aroma marketing in the selected company in tourism
RAMBOVÁ, Kristýna
This bachelor thesis explores aroma marketing as an innovative approach to improve the marketing position and competitiveness of a tourism business. The thesis combines theoretical foundations which are then used in the practical part where the effects of cinnamon aroma through diffusers and coffee aroma are tested. A questionnaire survey and emotion analysis using FaceReader were used to assess guest reactions and the influence of scents on the perception of the environment. The purpose of this bachelor's thesis is to assess the benefits and effectiveness of aroma marketing and determine if it has a positive effect on the overall customer experience and ambiance. The results of this study provide valuable information for the business, contributing to creating a competitive advantage.

Testing of sensory abilities of assessors: studying of smell and vision sensitivity
Hýsková, Eva ; Janoušková, Eva (referee) ; Vítová, Eva (advisor)
This diploma thesis was focused on visual and olfactory senses and their role in the sensory evaluation. The requirements for assessors working in sensory analysis, for testing place and requirements of the Czech Institute for Accreditation for the accreditation of laboratories working in the field of sensory testing are summarized here. An overview of methods and legislation in the field of sensory analysis is also presented. Methods for studying of smell and vision sensitivity of assessors were selected in the experimental part of this thesis. The methods were verified in the sensory laboratory, validated and standard operating procedures have been developed to the individual methods.

The role of disease-related olfactory cues in diagnostics
Adamová, Adéla ; Schwambergová, Dagmar (advisor) ; Eretová, Petra (referee)
Correct and prompt diagnosis of the disease is the key first step to successful treatment. At the same time, for many diseases, early diagnosis is even essential for a complete recovery of the organism. However, many of the commonly used diagnostic tools are quite demanding and time-consuming for patients, as they consist of a whole set of examinations. One of the other potential options is diagnosis based on human body odour. Human body odour is somewhat stable, but there are factors that can alter it. One of these factors is certain diseases. Qualitative and quantitative changes in the substances contained in the body odour of patients can be identified by certain animals, particularly trained dogs, or by analytical methods such as gas chromatography. Recently, a number of studies have investigated the use of these methods, seeking to clarify the breadth of their use while highlighting their non-invasiveness. The aim of this bachelor thesis is to provide a theoretical review of studies that deal with the diagnosis of diseases from human body odour, particularly using animal olfaction. The thesis summarizes the literature focusing on this topic, highlights the advantages and disadvantages of diagnosis using body odour, critically evaluates the methodology used in the presented studies and points...

Olfaction-mediated behavioural defence mechanisms in humans
Schwambergová, Dagmar ; Havlíček, Jan (advisor) ; Croy, Ilona (referee) ; Polák, Jakub (referee)
This thesis consists of two parts. The first part introduces the importance of behavioural defence mechanisms, specifically the behavioural immune system and mainly in humans. I review current knowledge regarding behavioural defence mediated by odour cues. Although behavioural defence mechanisms are important for all individuals who live in social groups, I focus on mate choice, because that is the context in which olfaction-mediated behavioural defence is studied the most. Subsequently, the importance of olfaction is demonstrated using the example of self-inspection and I discuss how the behavioural immune system may be intertwined with this relatively understudied behaviour. Finally, last chapter deals with associations between olfaction and other modalities that play a role in the detection of cues which help select a healthy and immunocompetent partner. In the second part of the thesis, I present nine papers: three reviews and six empirical studies. The review papers summarise the functioning of the behavioural immune system, olfaction- mediated pathogen avoidance in mammals, and the merely weak association between attractiveness ratings based on different modalities. The first empirical paper investigates whether the threat caused by the Covid-19 pandemic led to increased perceived disgust,...

Laboratorní test disasortativního párování u hraboše polního - literární rešerše
BÍLKOVÁ, Pavlína
Petrásková P. (2019): Laboratorní test disasortativního párování u hraboše polního - literární rešerše [Laboratory test of disassortative pairing in the common vole - literature search. Bc. Thesis in Czech]-49 pp. , Faculty of Sciences, University of South Bohemia, České Budějovice, Czech Republic. The aim of this work is to use the literature research to map current knowledge about the effect of odour preference on reproductive success in mammals focusing on voles. As assortative pairing is referred to each form of non-random pairing. Most of the time is meant a situation in which individuals who have similar phenotypes pair more often. The opposite is the situation where individuals with different phenotypes pair more often. This is sometimes referred to as negative assortative or disassortative pairing. In particular, this study deals with non-random pairing among to body odour . These are mainly linked to genes for the major histocompatibility complex (MHC) in animals, which play a key role in the immune system. MHC gene products found in various body secretions form the specific odour of each individual. In the research part were searched question for following questions: How is the breeding partner chosen? Is Assortative or Disassortative Pairing More Frequent? What information does body odour convey? What channels is the odour information transmitted and received? How is odour preference testing solved in laboratory conditions? In the practical part, a plan of the experiment is presented in which T-labyrinth will play the main role in determining the odour preference. Under laboratory conditions, voles will have plenty of time to complete the process

Association between human body odour and health status
Schwambergová, Dagmar ; Havlíček, Jan (advisor) ; Vinkler, Michal (referee)
The subject of this thesis is to evaluate a link between changes in body odor and health status in humans. The main aim was to create a theoretical overview of the available studies concerning humans, which are compared with studies conducted on mammals. Alteration of body odor due to the ongoing disease may negatively influence not only the odor attractiveness of a potential partner, but also may cause changes in behavioral response to a chemical stimulus for other members of the species. One may assume formation of perceptual adaptations exhibiting sensitivity to markers of health status in both sexes. Recognition of ill individuals may be crucial during social interactions, to prevent transmission of pathogens, but in mate choice the health status may also serve as an important indicator of resistance to infection, which can affect the viability of the offsprings. The main contribution of this thesis is to summarize the knowledge and insights into the area related to changes in body odor, depending on the health status. Keywords body odor, health, sexual selection, attractiveness, olfactory perception

Role of body odour in partner relationship
Černý, David ; Kuncová, Lucie (advisor) ; Martinec Nováková, Lenka (referee)
Body odor is a good guide in mate choice, because it contains information such as the kinship, emotional state, or health condition of an individual, a person is able to perceive this information to a certain extent. The individual factors that affect the body odor will subsequently influence the preferences for the body odor as well. Those preferences are applied especially when seeking for a partner and at the beginning of the relationship. At the same time, however, it turns out that body odor affects even the process of partnership and the end of it. In the context of relationships and olfactory communication in humans, especially in the context of sexual life, the effect of pheromones is often discussed, which is the subject of the last chapter. The aim of the work is to gather and critically evaluate existing studies dealing with the role of body odor in the partnership and to suggest possible directions for further research. Keywords: smell, pheromones, partner preferences, mate choice

Mechanisms of human body odour production
Hrubová, Noemi ; Havlíček, Jan (advisor) ; Stopková, Romana (referee)
The sterile secret of skin glands is not immediately odoriferous. The characteristic body odour is released after microorganism transformation of the secreted compounds. The aim of the work is to elucidate the mechanisms of the body odour production. The major contributor to the body odour are volatile fatty acids hydrolysed from glutamine precursors, structurally unusual long- chain fatty acids or lipids. Another component are sulphur compounds, mainly secreted as the Cys-Gly-(S) conjugates, and steroid substances. The genus Corynebacterium is associated with these transformations and intense body odour. The composition of the resident microflora varies depending on age and gender. Axillary odour with large apocrine secretion has probably biggest importance for human chemical communication. Apocrine glands secretion starts during puberty and decreases in postmenopausal women. There are quantitative differences between gender composition of sweat. In the Asian population is more common the recessive homozygosity of the ABCC11 gene which is associated with lower body odour intensity. Also MHC proteins effect body odour and they seem to play a role in mate choice. To some extent, the environmental factors such as diet or emotions influence body odour. Knowledge of mechanisms behind body odour...
