Networking Subsystem Configuration Interface
Lichtner, Ondrej ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
Cílem diplomové práce je návrh síťové konfigurační knihovny s důrazem kladeným na přenositelnost mezi operačními systémy na bázi Linuxu a BSD a rozšiřitelnosti podpory knihovny. V druhé kapitole práce zkoumá dostupné konfigurační rozhraní obou operačních systémů. Detailně pak rozebírá vlastnosti rozhraní Netlink socketů, které je primárním konfiguračním rozhraním pro síťové prvky na Linuxu, a systémové volání ioctl, které má na Linuxu menší schopnosti, ale zato je primárně používané na BSD a jiných UNIX systémech. Jsou též zkoumané rozhraní pro konfiguraci rozdílných firewallů. V třetí kapitole je práce zameřená na konkrétní typy síťových zařízení, specifika jejich konfigurace a jejich návaznost na rozhraní jádra popsané v druhé kapitole. V čtvrté kapitole jsou formulovány požadavky na konfigurační knihovnu: jednoduchá rozšiřitelnost, přenositelnost na různé operační systémy, podpora sledování změn a událostí a rozšiřitelnost o různé typy uživatelských rozhraní. Na základě výzkumu z předcházejících dvou kapitol je přednesen návrh knihovny. Návrh definuje konfigurační rozhraní jako hierarchii abstraktních tříd, oddělených od implementace. To umožnuje mít současně několik implementací stejného konfiguračního rozhraní i v rámci jednoho operačního systému. Jako vstupní rozhraní knihovny je definovaná třída LibNCFG, která má na starosti tyto konfigurační objekty vytvořit namísto uživatele. Tímto je dosažená jednoduchá rozšiřitelnost knihovny o nové rozhraní operačních systémů i o podporu konfigurace nových síťových prvků. Podpora pro nové uživatelské rozhraní se dá implementovat jako nová služba, která zabaluje rozhraní knihovny a poskytuje jiná rozhraní. Pro podporu sledování změn poskytuje třída LibNCFG metody pro registraci zpětných volání pro definované události. Ve čtvrté kapitole práce detailně popisuje rozhraní třídy LibNCFG, modulu Common a tříd NetDevice, EthDevice a BondDevice, které definují konfigurační rozhraní příslušných typů síťových zařízení. Pro tyto třídy jsou implementované konkrétní třídy NetlinkNetDevice, NetlinkEthDevice a sysfsBondDevice a popsané jejich implementační detaily. V páté kapitole je popsaná ukázková aplikace, která byla implementovaná pro účely předvedení jednoduchosti použití konfigurační knihovny. Nakonec jsou v závěru shrnuté výsledky práce a je vedena diskuze o možných vylepšeních a o pokračování projektu.

Structual welding of aluminium alloy
Blahák, Petr ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated in frame of engineering studies branch 2303R002 presents a project that contains welding a structure made of aluminium alloy. There were two usable methods selected, based on literal study of welding aluminium alloys, TIG welding and friction welding, and these were compared with alternative methods of joining, hard soldering and bonding. A work procedure was made for TIG method, soldering and bonding and four experimental joins were made thereafter. Project compares these methods mainly in economical way, also in way of technological difficulties and in way of observance the strength of base materials. Project also deals with problems with lowering strength of base material in heat affected area, burn out of thin material, tendency of aluminium to fill with hydrogen, quick oxidation and consequent hard surface layer emerging on the aluminium.

The first minutes of the life physiological newborn in the mother's eyes
PRŮCHOVÁ, Kateřina
The first minutes of life of newborn individuals and the way they spend them are very important moments. A new human is born to this world from the long-familiar environment which provided them with great security and now they are coming into a totally different environment. Our objective is to make this transition as natural as possible. The most important is to let mother and newborn together as much as possible. This way we give them feeling of safety and security, the newborn will be able to listen to the mother´s heart beat and their first mutual glances occur. We can negatively influenced those moments either if we interfere their course too much by doing procedures which could be postponed off the immediate post-delivery period or if we are not able to offer the environment which is plesant for mother and newborn. In the research part of this thesis I used a qualitative research method. The aim of the study was to describe current nursing practices for physiological newborn after birth in a delivery room and compare them with the recommended practices in this area. The objectives of this thesis were accomplished, after interview analysing I described mothers´views on the topic and compared the process of a nursing care at the first treatment of a newborn in a delivery room with recommendations for this area. The survey was conducted in a medical facility (Hospital České Budějovice a.s.) where the care provided corresponds to valid standards for nursing care in neonatology. Although the care provided is in absolute accordance with the recommendations, mothers themselves in interviews in lesser or greater extent reflected a certain need of empathy from the side of the staff, more support especially in case of primapara, and this concerns not only them but also partners who accompany women at deliveries and who meet unfamiliar situations and gain new experiences.

Bonding - opinions of medical staffs and mothers
KŘIVANOVÁ, Šárka
Bonding is a process by which is created a relationship between mother and child. The foundations of emotional bonds are built, foundations of a loving relationship. In its course we try to aim a maximal contact between mother and her newborn child and so improve its start to life. Right support of bonding contributes not only to psychological and emotional site, but to immunologic as well. (Mrowetz a kol., 2011). The theoretical part is concerned mainly with bonding description, further description of a delivery without bonding support and the participation of nearby persons by the delivery or the woman psychic and prenatal psychology. Research part of this thesis was concerned with investigation about bonding as a whole by 3 groups of respondents. The first group was built by six midwifes working in delivery rooms in different hospital in the area of Czech Republic. Second part was put together from six children's sisters, who work with at newborn department and came to care for newborns after delivery. Sisters form different hospitals were approached in this case too. To the last group were six women integrated in various stage of pregnancy. What pregnancy was it for the woman was not decisive for interviews. Before processing of this thesis were set two goals. First goal was to find out, if mid wives and children's sisters at delivery room know, what it is bonding and how to use it with advantages for the newborn and how to establish the first contact between mother and child. Second goal is to find out, to what extend is a pregnant woman informed about possibilities to improve the start of the newborn to life with the help of bonding. From these two goals emerged tree research questions, from which two were for medical staff (Does the medical staff have suitable and adequate conditions for bonding? In what does medical staff see the contribution of bonding?) and one for mothers (What do you imagine under the term bonding and in what do you see its sense?). For these research questions were seeked answers by getting and processing of each half structured interviews. For the research process was used the qualitative method. From the results of the research emerged, that medical staff does not have sufficient information about bonding usage by delivery. They answered identically to given bibliography to the basic questions, however they did not fully master particular elements of bonding. Midwives and newborn´s sister believe they do not have enough staff for adequate bonding usage, however they are willing to support bonding on mother-to-be wishes. They are not so obliging by the C-section. In this case they present unsatisfactory conditions for its usage like not enough staff, time and space. To the second research question was given this answer. The contribution of bonding sees the medical staff in the creation of positive bond between mother and child and in god adaptation of the child to new environment. According their meaning does bonding bring a positive experience form the delivery and improving of mother role admission, less stress for mother and child and even quicker after-delivery adaptation. Mothers imagine under the term bonding a contact of a mother with her child. The meaning of bonding they see in the building of psychic contentment and general soothing of mother and her child, in reaching better relationship between mother and child and in quicker lactation start. It is necessary to continue in raising of public awareness concerning bonding. In my opinion is necessary to realize more lectures and trainings about bonding contributions, especially from the site of psychologist so the contributions of bonding to the benefit of mothers and newborns can be used.
