Torrent Peer Monitoring
Bezděk, David ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
This master's thesis deals with analysis and implementation of methods for BitTorrent monitoring focusing on the Mainline DHT protocol. The aim of the thesis was to create a system, that will be looking for BitTorrent peers that participe in the illegal file distribution. Another task of the system was to collect and analyze data for counting size of the BitTorrent network. That was achieved by taking over of existing method. The system was designed and implemented as a module for monitoring of cybernetic crime. It also defines an interface for storing and sharing data, that provides data evaluation, easy data manipulation and serves for possible future extensions.

BitTorrent Tracker-Less Peer Monitoring
Vaško, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
The goal of this thesis is to effectively monitor peers within BitTorrent network. This research is based on distributed hash tables, specifically MLDHT. In the last decade, focus has also been on efficiency of monitoring within network. Existing algorithms do not provide actual efficiency therefore it is recommended to introduce an estimate accuracy using Bernoulli process. The goal of monitoring is to ensure the highest success of peer search. The work focuses on designing and implementing Bernoulli process model. The measurements show that, the in-depth search (LIFO) is better in the short run. The work focuses on the efficiency of time monitoring, estimation of the peer search error and efficiency using the modeled Bernoulli process. Result of this work is the recommended monitoring time with high efficiency.

Synchronization and Backup od Data under OS Linux
Marťák, Adam ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
This bachelor's thesis deals with synchronisation and backup of data under Linux OS. The aim of this paper is to design and implement a custom tool for data synchronisation and backup for Linux OS. The solution was inspired by the program Git. The architecture peer-to-peer was used to implement the project. The tool uses a database to store metadata and data itself. Based on testing, it was found that the tool has a certain overhead during the data synchronisation and the process of backing up. These results are discussed and other proposals are submited in the conclusion.

Retrospective Reflection on the Influmence of Drugs during Their Adolescence
VOPÁLENSKÁ, Markéta
This bachelor thesis deals with the retrospective view of adults on the effects of drugs during their own adolescence. The theoretical part describes in more detail the period of adolescence, drug division, causes of drugs using and possible prevention. It also deals with the role of adolescence with using drugs and the desire to fit in with the others. The research part is processed using a qualitative methodology, which is is based on two in-depth interviews with respondents who used drugs in adolescence but were able to resist their addictions at a later age. I mainly researched what specific circumstances were important in drug use, and subsequently what forced them to stop using them and how it affected them into their current lives. Data analysis is performed by interpretive phenomenological analysis.

Peer Element in Prevention of Children's Injuries at Primary School
Kalinová, Eva ; Marádová, Eva (advisor) ; Kovaříková, Miroslava (referee)
This diploma thesis engages in the issue of protection of children's health. It focuses on the prevention occurrence of accidents among children. The aim of this thesis is to refer to the importance of this topic and to realize the project, in which primary school pupils have an opportunity to reduce the rate of accidents actively. The theoretical part presents epidemiological data about childhood's accidents, warns of the specifics of psychomotor development of primary school children. In addition to inform about the methods of intervention and prevention levels and it gives an overview of organizations which engage in the protection of health. The practical part presents the results of a survey that addressed the teachers in point of view on idea of leadership in teaching by older primary school pupils. Then constitute the specific prevention project in which fifth grade pupils prepares a lesson on the subject of injury prevention for the second grade pupils. Conclusion the practical part includes modifying the original project and recommendations for teachers, based on the experience gained in implementing the project.

Health care professional awereness about of psych-social intervention care
DAŠKOVÁ, Veronika
Awareness of psychosocial intervention care among healthcare professionals Abstract Aims, research questions and hypotheses: The aim of the research is to evaluate the awareness of healthcare professionals about psychosocial intervention care. Goal 1: Identify the real situation in psychosocial intervention care. Goal 2: Identify the possibilities of offering and using psychosocial intervention care in healthcare facilities. Methods and research file: Quantitative and qualitative data collection techniques were used. A quantitative survey was conducted using questionnaires distributed to healthcare professionals in selected organizations (Liberec and Jičín Regional Hospital and University Hospital Hradec Králové). The size of the research group is 170 respondents. A qualitative part was realized with semi-structured interviews with peers in the same organizations. In total, we reached five peers. Results and conclusions: The research shows that health professionals perceive their work as mentally and physically demanding. The difficulty of the healthcare profession is perceived through all age categories, across disciplines and regardless of the length of practice. Half of the respondents considered a change of a job due to mental and/or physical demands. More than half of health care professionals are aware of psychosocial intervention care system. The survey further shows that healthcare professionals find themselves in extreme mental stress that would potentially require psychosocial intervention care. Only a low percentage of healthcare professionals will use this service. A qualitative survey shows that healthcare professionals are afraid of loss of anonymity when using psychosocial intervention care. This is related to mistrust in peers. From a peer point of view, it is important to be more aware of this service, helping healthcare professionals in their psychologically demanding occupation, which will increase their use and efficiency. The output of this thesis will be a proposal to include topics on psychosocial intervention care in regular training for employees.
