Fanderlik, Vítek ; Vondrášek, David (advisor) ; Fiala, Miloš (referee)
Title: Analysis of diving locations in north-eastern Bohemia and creation of a web application Objective: The main objective of this bachelor's thesis is to create an open web application of diving sites situated in north-eastern Bohemia, using the map software called Mapotic. Operation goal is creating a description of the areas themselves from a diver's point of view, cultural-historical or geographical-bathymetric description. Methods: Study of current and historical sources of the issue, a survey for different locations. After analysing the information of the locations, the method of summarizing key data was used to create a web application of diving areas. In order to create high-quality bathymetric maps - the consultations with map experts also took place. Results: There are clear documents of individual areas and an online open web application mapping selected diving locations in north-eastern Bohemia. Keywords: diving, diving locations, Mapotic, map software, web application, bathymetric maps

Risks related to open water diving and their prevention
OBORNÁ, Veronika
This bachelor's thesis focuses on the risks associated with open water diving and their prevention. Three objectives were determined to elaborate this thesis. The first objective was to find out what kind of knowledge professional and recreational divers have about the risks related to open water diving. The second objective was to examine what knowledge divers have about preventive measures related to open water diving. Last but not least, the third objective was to determine what barriers regarding the open water diving are perceived by divers. The bachelor's thesis consists of a theoretical and a practical part. The theoretical part is divided into chapters and subchapters describing the history of diving, fundamental diving equipment, basics of physics for divers and physiology related to diving. The heoretical part also describes the most common injuries and diseases occurring during diving, proper first aid as a reaction to them as well as their treatment. Finally, a part of the theory is devoted to the prevention of undesirable situations during open water diving. In the practical part of this thesis a qualitative research was applied. Data collection was conducted through semi-structured interviews. The research sample consisted of ten divers of different ages and different lengths of experience. Five informants were professional divers and five informants were recreational divers. The data obtained from the interviews were processed into four categories, which were further subdivided into subcategories. Using the qualitative research, it was found out that both professional and recreational divers have the necessary knowledge regarding the risks associated with open water diving. Despite essential knowledge and efforts to follow preventive measures, all but one informant experienced a crisis situation during a practice dive, which always turned out well due to proper theoretical preparation for these risk situations. All informants are aware that the biggest risk is the diver himself and overestimation of his own abilities. Regarding the knowledge of preventive measures related to the open water diving, there were differences between the knowledge of professional and recreational divers. All informants had the necessary awareness of the discussed topic, however it was clear that professional divers were more familiar with this issue. All informants were knowledgeable about the necessity of diving training, proper diving equipment, preventive measures and first aid procedures including cardiopulmonary resuscitation in case of an emergency situation. Moreover, it has been found out that divers perceive certain obstacles when diving in open water. In addition to poor health or psychological conditions being a barrier to diving, informants also determined low quality natural conditions as a barrier too. Deteriorated natural conditions were seen as a barrier mostly by recreational divers, whereas professional divers dive all year round and in all kinds of conditions. From the results of the research, it was ascertained that divers have sufficient knowledge of the risks associated with open water diving. Furthermore, informants have sufficient knowledge of preventive measures, which enables them to correctly assess certain situations. The fact that the informants consider the deteriorated natural conditions as a barrier to open water diving indicates that they are concerned about the prevention of risks associated with open water diving. This thesis highlights the importance of knowledge of the risks associated with open water diving and their prevention. The results of this bachelor's thesis can be used to supplement the knowledge of some divers, as a teaching material for novice divers or for health professionals who want to be aware of diving-related diseases and acute conditions related to diving itself.

Risks associated with diving and their prevention
DIVIŠOVÁ, Anna
The topic of this bachelor thesis is called: "Risks related to diving and their prevention." The theoretical part is mainly focused on health risks which arise during scuba diving and follow-up prevention of the health risks. Furthermore, the following topics are mentioned in the theoretical part: a history of diving, biophysical concepts, and necessary equipment. Because of this topic, it was important to include chapters about first aid, treatment and medical fitness for diving. A reduction of health risks was chosen as the main objective in the practical part. There were created 3 research questions. 1. What is the training of divers? 2. What is currently the prevention of health damage during diving? 3. How can we reduce the risk of health damage? The qualitative research measurements were used for the creation of the research part of this bachelor thesis. A semi-structured interview containing 24 questions was created to get the data. There were 6 divers chosen for the interviews, 3 professional divers and 3 hobby divers. According to the results, it was found that there is a fundamental difference in the knowledge of the divers about this topic. Very often the risks are caused by insufficient preparedness and knowledge of the diver, not handling of the panic and stress, and a wrong reaction. Disobeying of precautions and principles often contributes to that. The results of this bachelor thesis may be helpful in completing education and information of divers, but also medical staff.

Influence of NITROX breathing mixture on psychosomatic conditions of diver, its preparation and usage in FRS CR conditions
KARVÁNEK, Jakub
The aim of this bachelor's thesis is to assess the effect of the NITROX breathing mixture on the diver's psychosomatic state in comparison with air. In an effort to increase safety and facilitate very physically and mentally demanding interventions, divers have the opportunity to use the NITROX breathing mixture (NITrogen - nitrogen and OXygen - oxygen), where oxygen is represented by more than 21%, unlike ordinary air. A frequently cited benefit is less physical fatigue after a dive with this mixture. One of the tasks of this thesis is therefore to confirm or refute the following hypothesis: "NITROX breathing mixture has a positive effect on the psychosomatic state of the diver, who is less subjectively physically and mentally tired after a dive with this mixture." Another task is to evaluate the preparation of the NITROX mixture and its use in interventions by diving groups of the Fire and Rescue Service of the Czech Republic. To obtain the results, a questionnaire survey was used, in which divers answered a set of questions concerning their subjective physical and mental condition after performing two independent dives. The dives differed only in the breathing mixture used, their profile was identical. The section relating to the preparation and use of this mixture was prepared on the basis of interviews with divers and leaders of diving groups. The results of the thesis show that after dives with the NITROX mixture, divers report slightly more positive subjective feelings regarding the physical condition. On the other hand, the results also showed that NITROX has a more negative effect on divers in terms of subjective mental state. The NITROX mixture is prepared mainly by the gas mixing method. During diving interventions it is primarily used as a decompression medium. The conclusions of this thesis did not confirm the assumed hypothesis. The recommendation for diving groups is therefore: (1) to continue to use the NITROX breathing mixture, especially as a decompression medium, and (2) to increase the frequency of separate dives with this mixture so that they are not so stressful for divers in the future.
