WI-BIO: redes de monitoramento de pacientes em ambientes de automação hospitalar utilizando o padrão IEEE 802.11

The monitoring of patients performed in hospitals is usually done either in a manual or semiautomated way, where the members of the healthcare team must constantly visit the patients to ascertain the health condition in which they are. The adoption of this procedure, however, compromises the quality of the monitoring conducted since the shortage of physical and human resources in hospitals tends to overwhelm members of the healthcare team, preventing them from moving to patients with adequate frequency. Given this, many existing works in the literature specify alternatives aimed at improving this monitoring through the use of wireless networks. In these works, the network is only intended for data traffic generated by medical sensors and there is no possibility of it being allocated for the transmission of data from applications present in existing user stations in the hospital. However, in the case of hospital automation environments, this aspect is a negative point, considering that the data generated in such applications can be directly related to the patient monitoring conducted. Thus, this thesis defines Wi-Bio as a communication protocol aimed at the establishment of IEEE 802.11 networks for patient monitoring, capable of enabling the harmonious coexistence among the traffic generated by medical sensors and user stations. The formal specification and verification of Wi-Bio were made through the design and analysis of Petri net models. Its validation was performed through simulations with the Network Simulator 2 (NS2) tool. The simulations of NS2 were designed to portray a real patient monitoring environment corresponding to a floor of the nursing wards sector of the University Hospital Onofre Lopes (HUOL), located at Natal, Rio Grande do Norte. Moreover, in order to verify the feasibility of Wi-Bio in terms of wireless networks standards prevailing in the market, the testing scenario was also simulated under a perspective in which the network elements used the HCCA access mechanism described in the IEEE 802.11e amendment. The results confirmed the validity of the designed Petri nets and showed that Wi-Bio, in addition to presenting a superior performance compared to HCCA on most items analyzed, was also able to promote efficient integration between the data generated by medical sensors and user applications on the same wireless network

Infância - memórias: cenários - personas

Infância is undoubtedly memory, high qual ity l iterature, reputable, as the story moves between f ict ion and reality. Personal and social history, wi th such a sense of reality, causing the reader to prof it f rom the honesty and the sinceri ty producing, in this work, remarkable results in a constancy of cl ippings, f rame -by-f rame. Memory and obl ivion are this work guidance. We aim to denounce the relat ionship between the chi ld and violence, and as it is a memorialist ic text , we see the importance of f ict ion for this type of narrat ive to be sustained. I aim thereby show the tone of this report humanizing memories, its deep and decisive meaning, through the memories concepts by Le Gof f , by Seligmann-Silva and by Ecléa Bosi. I t is also through the theories of Jeanne Marie Ganegbin that I just ify the concept of remembering and forget t ing, and also it is also according the concepts of Eliane Zagury that I give support to the importance of autobiography as a a mean of expressing the reported memor ies. Final ly, in Infância, there is no room for fantasy. The lyricism that overwhelms, throughout each chapter, commands the author's imaginat ion. The need to invent gives way to the need to test ify, to denounce. And this t ransit ion occurs gradually, slow as Gra c il ia n o s c h i ld li f e , d u e to such humiliat ion and submission
