Web Application for Managing Notes
Hrdina, Jan ; Očenášek, Pavel (referee) ; Burget, Radek (advisor)
The thesis deals with design and implementation of a web application for managing tree-structured notes. Its aim is to fulfill the true potential of using computers in this area. It tries to achieve this goal using (1) multiple ways of viewing and editing one data, (2) focusing the data-model primarily on the meaning of stored information instead of appearance and (3) implementing tools for interactive work with text (e.g. attaching multimedia). Apart from the application design itself, the text briefly goes through modern trends in web applications development, it defines the basic concepts in relation to existing tools for managing notes and outlines wide possibilities of further development. The application itself was implemented using technologies such as Polymer, TypeScript or Firebase.

Application Development Framework for Peer-to-Peer Collaboration
Hrdina, Jan ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
The thesis deals with the design and implementation of the application framework for the creation of collaborative web editors that enable peer-to-peer collaboration in real time. The thesis summarizes existing approaches for data replication, from which M. Kleppmann's CRDT (conflict-free replicated data type) for JSON is chosen as the most suitable. Using the resulting framework, the created content can be safely shared in groups of peers, where each member can be assigned different permissions. Own communication protocols based on WebRTC, WebSocket and WebCrypto are designed and implemented for P2P connection establishment and subsequent communication. The framework allows to resolve conflicts and work independently without an Internet connection. For a consistent user experience, the library includes a set of user interface elements for managing friends, groups, and other common tasks. The framework is implemented using functional design patterns implemented in the ReasonML language. The functionality of the result is verified by creating an example application of the mind map editor.

Travelogue of Heinrich von Zedlitz
Loučka, Václav ; Svátek, Jaroslav (advisor) ; Hrdina, Jan (referee)
The objective of this thesis is to make available in Czech translation the remarkable text of the travel diary of the Silesian knight Heinrich von Zedlitz. This subject of the king of Bohemia undertook a pilgrimage to the Holy Land in 1493, recording his experiences and knowledge in the form of diary entries for the instruction of future pilgrims. It is important that he did not travel alone, but rather joined a large, prestigious group of mainly noble pilgrims in Venice. Some of them also kept diaries or made various notes, several of which have survived, so the possibilities of mutual comparison of these materials are quite extensive. Among other things, this work is one of its prerequisities. The first part contains basic information about the travelogue in question and, above all, an analysis of several events mentioned in its text, in comparison with the better-known, Czech-written travelogue of Jan Hasištejnský of Lobkovice, which has already been published several times. The second part then includes the actual translation of Zedlitz's travelogue from early modern German into modern Czech and relevant appendices (itinerary, maps) facilitating orientation in this translation.

Hrdina, Jan ; Doubek, David (advisor) ; Levínská, Markéta (referee)
This dissertation deal with developmental types of boys in the fourth grade of basic school. It is divided into two parts. In the theoretical part I am dealing with possible reasons of making a relations between boys, focused on social psychology, socio-culture and psychological aspekt. In empirical part, which is based on my own observation of school class, the structure of relations between boys is completely described. The goal of empirical part is to describe boys as individuals and according to their appearances, interests, family relations and games, which boys like to play in school class, divided them into several groups. Games in school class are mentioned in separate paragraph. According to my own observation four groups of boys were established. Each group has typical character and their members have specific interests and own attitude to class. These groups were created because of likings between boys, similar attributes of boys and attitudes of boys to school. These results are elaborated in the conclusion of my dissertation.

The Kingdom of Bohemia and the dynasty of Luxembourg in the French chronicles of the 14th century
Lošťáková, Kateřina ; Nejedlý, Martin (advisor) ; Hrdina, Jan (referee)
Since the beginning of the fourteenth century the Czech kings and their kingdom started to make significant appearance in the French chronicles. The sudden interest of contemporary historians was sparked mainly by the ascension of the Luxembourgian dynasty to the Czech throne in 1310. The relations that existed for a long time between France and Luxembourg were thus transfered to Bohemia, who se young king John the Blind soon became a French ally in the ongoing conflict with England. To the history of the Warfare, which is traditionally called the Hundred Years War, are devoted also the works of two of the most important late-medieval writers, Jean le Bel of Liege and Jean Froissart of Valenciennes. Modem historians have had for a long time a tendency to dismiss their chronic1es (Froissart' s in particular) as historically inaccurate and thus unreliable sources. But such a refusal implies a serious misunderstanding of both authors' intention, for their main goal was not to precisely narrate the facts but rather to adjust them to better suit their idealised image of social order. Bearing that in mind we can clearly see that the presence of Czech kings in Froissart's and le Bel's chronicles does not generally reflect their real deeds, but rather the symbo1ic part they play to enhance the glory of the French...

Art of the court of Czech and French sovereigns 1370-1420 - the social and historical background (differences and parallels)
Nussbergerová, Lucie ; Nejedlý, Martin (advisor) ; Hrdina, Jan (referee)
At the turn of 14th and 15th century, France and the Kingdom of Bohemia both faced very similar situation: progressive failure of royal authority against the background of sublimity and artistic prosperity in service of royal and aristocratic representation. Regarding Bohemia, this period is adherent to the reign of Wenceslas IV. (1378-1419), the son of the Holy Roman Emperor Charles IV. His dynasty was related with French kings, during this period it was Charles VI. (1380-1422), called Charles the Mad. The end of the 14th century was a time of insecurity and fear, especially when both of the main powers, secular and spiritual, had been continually weakened. Western Christianity was divided between two, and later even among three popes, residents in Rome, A vignon and Pisa (since 1409). The main task for the kings was to end this situation and to deci de which of these popes was the only one who had been legaly elected. This question was crucial for France and the Holy Roman Empire and it was also the main difficulty in their mutual political relations. Each kingdom also had problems with their own political situation: in France the war with England and subsequent civil war among the members of the royal family. In Bohemia it was the relation with the Holy Roman Empire, because Wenceslas IV. inherited the...

Papal indulgence charters in Central Europe under the pontificate of Boniface IX (1389-1404). A comparative study
Hrdina, Jan ; Hledíková, Zdenka (advisor) ; Hlaváček, Ivan (referee) ; Šmahel, František (referee)
The goal of the dissertation i s to understand the agency of the Roman pontificate in Centra! Europe during the Great Schism (1378-1415/17), with a special focus on the papacy of Boniface IX (1389-1404). In order to analyze this question, I used indulgence charters, one of the more typ i cal kind of documents produced by the papal office. Unlike his predecessors as well as immediate successors, Boniface IX issued indulgence charters to ecclesiastical institutions in the Roman obedience in truly mass quantities. My analysis was based on the study of approximately 1,660 individua! cop i es in secretarial registers of the Vatican Archive, Registra Lateranensia, and on approx. 260 extant copies in the archives of recipients.
