Posouzení vlivu podmínek skladováni loupané dýhy na její vlhkost v závodě ALFA Solnice
Borek, Ondřej
The purpose of this bachelor thesis is to assess the influence of the conditions of veneer storage in technological processes which are mainly dependent on the humidity of the peeled veneer. These are in particular the technological parts behind the peeling machine and the drying room from which the peeled veneer is transported to the warehouse. Determination of the moisture of the peeled veneer was carried out by the weighting method. Thanks to the moisture results it was judged how moisture was variable before the drying process which is then reflected on the dried veneers that are transported to the warehouse. Conclusion is how to modify the sorting and storage of peeled veneers in the production process so that the moisture content of peeled veneers is as balanced as possible during storage.

Vliv třídění brambor na změny jejich technologické kvality
Memedliaeva, Edelina
The aim of the thesis was to work out a research of the literature and determine the influence of the size fraction of potatoes on their technological quality. In cooperation with a company Beskyd Fryčovice, a.s. the samples of their processed potato varieties were provided. Mass fractionation of the available potato tuber samples was performed and the selected quality parameters, which are important in terms of potato storage and processing, were then determined. The focus was on the amount of starch, nitrogen, magnesium, calcium and potassium in the dry matter. The study also includes the determination of the cooking value of tubers. One of the parts of the instrumental analysis was the determination of the texture properties of the tubers. Products of different size fractions of potatoes were produced and their sensorial qualities evaluated. The result of the study has confirmed that both weight grading and the variety have a decisive influence on the potato cooking value. The result of the experiments has also shown great variability in quality between the varieties. It has been confirmed that the chemical composition of the tuber sis also affected by their weight. During he experiments, there have also been produced the refined potato products, and the evaluation of their quality during storage has been performed.

Problems of triage during an emergency involving disabled people
HAVRDOVÁ, Jitka
Mass casualty incidents and their occurrence are a real threat not only to the society as a whole but also to emergency medical service providers, who, at the moment of the occurrence of a mass casualty incident, must completely change their approach to providing care and switch into the emergency regime. At that moment, high demands are placed on the entire integrated rescue system, both with regard to ensuring safety, preventive measures and organizing activities at the site of the mass casualty incident, andto providing quick and expert assistance. This bachelor thesis concerns mainly providers of emergency medical services during mass casualty incidents and problems of sorting of casualties. In case of a mass casualty incident, the situation requires a completely different approach to the treatment of the casualties than everyday work. In this situation, the individual medicine model when the emergency medical crew provides care to one patient only, from the initial contact to the transfer of the patient to a medical facility, does not apply. In a regime of mass casualty incident, it is necessary to set priorities for treatment, to carry out such treatment and transport the patient to a medical facility. The priority in such a situation is not to save everyone's life, but to eliminate the extent of injuries of the people to the minimum. The treatment of casualties at the site of a mass casualty incident is complicated by many factors that negatively affect the situation. In particular, there is a lack of time for decision-making and treatment, chaos, stress, panic, and in the initial phase also a lack of resources and forces, concerning not only the providers of emergency medical services, but the entire integrated rescue system. Since the on-site situation is optimized within thirty and sixty minutes of the start of operations, it is crucial in the initial phase to focus on the organization and management of the integrated rescue system units. The bachelor thesis is devoted to the issue of classification of the casualties on the site of amass casualty incident. The theoretical part deals with the topics of disaster medicine, the integrated rescue system and in the last part it is devoted to the classification itself. The theoretical part is based on expert literature and current legislation. In the part focused on the classification of the casualties, the individual methods for classification of casualties and scoring systems are analysed in detail, especially the START method and classification identification card, which dominate in our country. The practical part of the thesis is done in the form of qualitative research and compares the answers obtained by a semi-structured interview with two groups of respondents. Respondents were non-doctor medical personnel of the emergency medical service, one group from the Vysočina Region and the other from the South Bohemian Region. The content of the interview was divided into four categories, each focusing on a particular area of casualty incidents. The individual categories dealt with general and specific procedures at the site of a mass casualty incident, cooperation of the integrated rescue system and the issue of classification of patients. The aim of this thesis was to find out how the rescue workers are prepared for a mass casualty incident both theoretically and practically, how they evaluate the cooperation within the whole integrated rescue system. The aim of the thesis was also to verify the theoretical knowledge of the respondents concerning this area of interest and the procedures. The results obtained by the interview and their analysis are included in the chapter Vyhodnocení rozhovorů. The research questions and their results are discussed in the chapter Diskuze. The overall conclusion is included in the chapter Závěr.

Determining the possibilities of increasing binding potencial of fly ash for the usage in cement composites
Jančaříková, Denisa ; Ďurica,, Tibor (referee) ; Klečka,, Tomáš (referee) ; Kulísek, Karel (referee) ; Hela, Rudolf (advisor)
The deliberate use of fly ash in the production of concrete has been used for decades, but recent trends tend to maximise its utility properties. These are different types of activations from chemical through thermal to mechanical. An alkaline agent is added to chemical activation which, by etching the glass structure of the ash grain, promotes its reactivity. Mechanical activation is mainly focused on granulometry and particle size distribution curve. In this thesis three mechanical activation methods are compared: separation the ash into fractions by grain size, mixing these fractions to achieve the ideal particle size distribution curve and grinding. Four types of ash were collected from the Tušimice power plant – ash from individual electrostatic separators (I, II and III) and SESYP ash which represents the total volume of production. Ash from individual separators differ not only in the particle size but also in the chemical composition and reactivity. Better properties generally have smaller ash particles. This is used by mechanical activation by sorting. When mixing the individual ash fractions, the aim is to achieve an optimal grading curve of either the ash itself or the fine particle set in the concrete. In this work, ash is only used to calculate the mixing ratio and the grading curve according to Funk was selected as optimal. The last compared option of activation was grinding ash. Grinding was carried out in an industrial mill for 15, 30, 45, 60 and 75 minutes. The efficiency of the modified ash was monitored for cement paste in terms of rheology and for concrete in terms of consistency, strength and durability. Based on the results we can say that mechanical activation by sorting is suitable for special purposes, but it’s necessary to realise that coarser ash fractions remain unused. When mixing the fractions to ensure matrix density, the efficiency was shown mainly on the durability characteristics. Grinding cause positive effect.

Trauma readiness of hospitals and emergency medical services of the Region
ŠKOLKOVÁ, Aneta
Trauma preparedness of medical care of a particular region represents the professional core of public health emergency preparedness. The key subjects are medical rescue service and hospital service provider. Current legislation imposes the providers of medical service with duty to work out the trauma plan which covers the system of activities used if some mass disaster happens. Topic of this diploma thesis focuses on trauma planning, specifically on mass health damage and on knowledge mapping and medical staff orientation in trauma plans and preparation on not common accidents with great number of wounded. I focused on non-medical staff of the regional emergency rescue service and the regional hospital. I focused on their knowledge and orientation in terms of trauma preparedness of the given subject. The theoretical part serves as a base for the research. It is split into chapters which deal with pre-hospital necessary care, co-operation of the integrated rescue system members and procedures of participating rescuers- mostly medical staff. I paid more attention to the terminology of mass health damage and separation of wounded at the place of an accident. I also described the subsequence of medical care at medical facilities. While searching for the level of preparedness of subjects for an uncommon accident I used the method of data comparison. There I focused on comparison of trauma plans of two subjects: the regional hospital and the regional emergency rescue service and I was researching the level of co-operation of both subjects based on the similarity of the trauma plans. In the second part I was mapping the medical staff knowledge of the trauma plan directive via quantitative research, for that purpose I used the survey. The respondents had to circle the correct answer. The questions were modified and applied to directives of both trauma plans. The respondents were non-medical workers of emergency rescue service in CB and non-medical workers of the hospital of CB. I tightened the workers of the hospital to trauma emergency staff and the resuscitation department staff. The survey consists of 28 questions. Five of it had rather an information character, they were searching for: the sex, age, years of praxis, education and a grade. The rest 23 were used for the statistic research. Those questions dealt with the theory presented in directives of both subjects. The received information I worked out in the chapter results. The comparisons of trauma plans were presented at charts. The survey was evaluated by nonparametric testing and a chi-square test of a good match.

The role of emergency medical services in the incident with mass health disabilities
ZRŮSTOVÁ, Simona
Medical rescue workers are routinely employed in emergency medicine. In emergencies where a large number of people are affected, knowledge of medical disaster practices is necessary. Within a second, the intervening crews should switch to another mode with a different approach to the patients than they use daily. The diploma thesis has set the following goals: to map the level of knowledge of medical rescuers in the field of emergency response with mass health impairment, their personal experience and, last but not least, education and training. Three research questions were asked to reach these objectives. What are the skills of medical rescuers in dealing with emergency health issues with mass health impairment? How do medical rescuers assess incidents with mass health impairment at which they were present and what is their attitude towards training and education in the field of dealing with emergencies with mass health impairment? The research part consists of interviews with two groups of participants: eight medical rescuers of the Medical Rescue Service of the Pardubice Region and the same number of medical rescuers of the Medical Rescue Service of the South Bohemian Region. These interviews supplemented the information provided by the crisis preparedness managers of both medical rescue services. The survey used a qualitative research strategy, conversations were recorded on a dictaphone, then processed into categories, subcategories, tables and evaluated. From the results of the work, a great difference in the knowledge of health rescuers in the field of emergency health problems can be seen. Participants of the South Bohemian Medical Emergency Rescue Service showed shortcomings in both the basic terminology and the solving of extraordinary events in particular, from reporting the situation with a report form to the classification of the disabled. On the contrary, the majority of participants in the Paramedical Rescue Service of the Pardubice Region would be able to file an initial emergency report and categorize and transport patients correctly. On the basis of the evaluated results, this difference in knowledge can be attributed mainly to the frequency and content of the training provided. In the case of South Bohemian participants, we can find the cause in the absence of practical training. The alarming results were noted in the participants' ability to use the START sorting method, from all of the sixteen respondents only one was able to answer there. The elaborated case report of an extraordinary event points to the fact that theoretical shortcomings can subsequently be transferred into practice.
