Recrystallization study of free-cutting steel by in-situ SEM/EBSD technique
Babinský, Tomáš ; Němec, Karel (referee) ; Petrenec, Martin (advisor)
Placing recrystallization annealing in a manufacturing proces is often necessary in order to restore plasticity of worked blanks right before working products to its final shape. For better understanding of processes which are taking place in a material during annealing the use of in-situ techniques is favorable. Such observations enable us to watch changes in the materiál in real time at the original spot. Observations at grain-level are ideally made with scanning electron microscope – SEM by electron back-scattered diffraction – EBSD. The technique makes watching nucleation, growth and potential coarsening of recrystallized grains possible. Special construction of a tensile stage allows us to watch changes of a sample during tensile tests which can be used in observing influence of MnS inclusions on plasticity of free-cutting steels. Materials studied in this work are commonly used free-cutting steel 11SMnPb30 and its lead-free alternative 11SMnBi30.

Anorexia nervosa - recovery
Chudačíková, Dominika ; Presslerová, Pavla (referee)
The rigorous thesis deals with anorexia nervosa as one of the basic forms of eating disorders, with emphasis on the very common chronic progression of this serious psychiatric illness. This thesis is based on the scientific fact, that conspicuous eating habits, constant control of thinking and behavior, as well as self-perception disorders, are observed in most cases, even in already cured patients. Risk factors such a long-term stress or prone personality, can result in the acute phase of anorexia nervosa. The rigorous thesis is qualitatively focused. The chosen methods of data collection are a questionnaire survey and a following semi-structured interview. The condition for participation in the research is the past experience with anorexia nervosa, without the current presence of the acute phase of this disease. The main goal of the rigorous thesis is to take a look, through specific stories of interviewed respondents, on individual ways of the recovery from the acute phase of anorexia nervosa, to map their current feelings, needs and burning issues. Based on the survey results, the outcome of the rigorous thesis are the specific recommendations for individuals who are prone to the emergence of recurrence of anorexia nervosa. These recommendations should lower the risk of relapse of the acute...

Ways of recovery in the context of Recovery approach
PETRŽÍLKOVÁ, Hana
The point of my final work is to introduce a social worker in multidisciplinary team, who works on the fundamental of Recovery way, like a way which is aimed on the picking responsibility of the client and his/her decision. Then to look for the client´s meaningful life and what part in this process is the part of social worker.The work is divided into four chapters, which try to introduce the mental disease and its difficulty. Next chapters are more aimed in Recovery attitude. Then there is used a CARe method, which comes from the Recovery way and how a social worker works with it. It shows his/her role in the multidisciplinary team, whis is using Recovery way, and how they work with people with mental disease. Finally I use the casuistry and particular ways of clients and the work of social worker, who works with the instruments that support the way back to recovery.

The Verification of the Use of the Heart Rate Variability in the Management of Training Process in Adolescent Mountain Bikers
KADLEC, Jakub
Cross-country Olympic (XCO) is one of the endurance sports. The training process of mountain bikers is very demanding because the rider must be complex in endurance and anaerobic skills. Alfa and omega of the training process is a periodization of training load and recovery. Heart rate variability (HRV) can help us assess body's condition and readiness for training. In the practical part of the work, an experiment was carried out, which was attended by eight adolescent mountain bikers. The intervention took place during the training camp. The total intervention time was four weeks. The participants were randomized into two groups. The first experimental group (ES) (n = 4) was a graduated training camp with a heart rate variability guided training load. The second group was a control group that used a classical predefined training plan. For evaluation of HRV training efficiency a VO2max test and 20 minutes time trial (20TT) on an ergometer were used. The results showed an improvement in mean power output during 20TT in the experimental group (PRE 303.5 W; POST 317.5 W) and relative values (PRE 4.58 W.kg-1; POST 4.68 W.kg-1). On the other hand, there were no changes in average power (PRE 308 W; POST 305.7 W) and relative values (PRE 4.20 W.kg-1; POST 4.20 W.kg-1). From a statistical point of view, there was no effect of HRV training on performance indicators (p <0.05). Our experiment failed to confirm the usefulness of HRV training for cyclists.

Respect to human dignity as a baseline of the quality of social work with people with mental illness
PODLIPNÁ, Martina
The thesis deals with the quality of mental health care, key aspect of which is the respect of human dignity. The first part characterizes the ethical and legal basis of human dignity. Further, it summarizes the ethical principles regarding human dignity formulated in codes of ethics of the particular professions represented in a multidisciplinary team providing services to people with mental illness. The next part describes selected approaches to this target group - the medical and rehabilitation models of treatment in particular. After that, the recovery approach is introduced. Recovery from mental illness is approached as a psychological process, in which people strive for a dignified life. This process has four fluid stages - hope, empowerment, self-responsibility and having a meaningful role in life. The final part discusses the contributions and difficulties of recovery approach in connection with dignity of people with mental illness. This approach fulfils the fundamental requirement of quality of social work, which is the respect to human dignity. The potential difficulties do not come from the principles of the recovery approach, but from its possible wrong implementation.

Peer consultants as part of the community teams in the organization FOKUS Vysočina
KUČEROVÁ, Barbora
The thesis deals with the representation of peer consultants in the community team, spe-cifically in community teams of the organization FOKUS Vysočina. The thesis is divi-ded into three chapters. The first chapter explains terms like: mental health or social work. The chapter also deals with the specifics of social work with people with mental illnesses. The second chapter is an introduction to the organization FOKUS Vysočina and specifically the work of the community teams. The chapter intorduces the target group, working representation, job description and methods of work in this organization. The third chapter explains the concept of peer support. It also focuses on the work of peer consultants in FOKUS Vysočina. The end of this chapter is partially composed of individual stories of peer consultants who work in FOKUS Vysočina. The stories inclu-de a personal view of the peer consultant's topic and its potential influence on the re-covery of clients. The thesis shows that the peer consultant is necessary and very significant for community teams. The statements of the peer consultants do not contradict the results of the studies and the knowledge from literature. It is evident that peer consultants in FOKUS Vysočina can have a very positive effect on the recovery of clients.

Comparison of match and training load of selected floorball women teams of the second and third highest league
NĚMCOVÁ, Petra
This thesis focuses on the comparison of match and training load of women in the second and the third highest floorball competition. From September to November 2019, diaries of training load and match load were kept in clubs Spartak Pelhřimov, SK Jihlava - Žďár nad Sázavou B and Rudý Dračice MLADÝCH NADĚJÍ. Based on these diaries, tables of individual load were created. Then the graphs were created, which show individual parts in percentage. The research has shown that at all three clubs, the training unit changes with regards to number of exercise days per week, as well as the number of exercise hours. The club of Spartak Pelhřimov trained 13 times in the watched period, which took altogether 1 255 minutes. The women from SK Jihlava had the longest training load during three months. The result total 5 410 minutes corresponds to 51 trainings. Rudý Dračice got in total 960 minutes in 13 trainings. The lowest match load was watched at club of Spartak Pelhřimov and it took 576 minutes. The match load at the two first league clubs was higher. Jihlava played in total 1 320 minutes and Týn 1 155 minutes. The main difference between the first and second league clubs is mainly the match load, which as significantly lower in the second league.
