Tecnologia para banho no leito de idosos e usuários acamados: uma contribuição para o cuidar humanizado

This study aimed to validate the technology at Bed Bath System, in view of bedridden elderly and their caregivers, with a view to transforming the conventional paradigm regarding the practice of bodily hygiene held in bath chairs adapted in long-stay institutions for the elderly. This is an experimental study involving 51 (fifty one) elderly and 17 (seventeen) caregivers of three long-stay institutions for the elderly of the city of João Pessoa. For data collection, applied initially to cognitive assessment scale Mini Mental State Examination, with the aim of tracking the subject group of elderly cognitively able to participate in the study. In the second phase, to measure the percentage of agreement and disagreement about the attributes of the subjects of the shower chair and adapted the system for bed bath, used a questionnaire with closed questions, Likert scale model of four (4) points, with a good reliability index (0.728), estimated by alpha conbrach, evidenced by the Wilcoxon test a significant difference (P<0.05) between the responses of seniors and caregivers about the attributes involving technology system in bath bed and bath chair adapted, confirming the perspective of the subjects that the two systems differ significantly. However, the system bed bath got greater degree of agreement for their use, characterizing this system is a technology that makes the differential bed bath pleasurable action, quality and humanized

Análise de confiabilidade de um moto-ventilador centrífugo: aplicação no sistema de pressurização de subestação industrial para garantia da segurança operacional na indústria petroquímica

The need of the oil industry to ensure the safety of the facilities, employees and the environment, not to mention the search for maximum efficiency of its facilities, makes it seeks to achieve a high level of excellence in all stages of its production processes in order to obtain the required quality of the final product. Know the reliability of equipment and what it stands for a system is of fundamental importance for ensuring the operational safety. The reliability analysis technique has been increasingly applied in the oil industry as fault prediction tool and undesirable events that can affect business continuity. It is an applied scientific methodology that involves knowledge in engineering and statistics to meet and or analyze the performance of components, equipment and systems in order to ensure that they perform their function without fail, for a period of time and under a specific condition. The results of reliability analyzes help in making decisions about the best maintenance strategy of petrochemical plants. Reliability analysis was applied on equipment (bike-centrifugal fan) between the period 2010-2014 at the Polo Petrobras Guamaré Industrial, situated in rural Guamaré municipality in the state of Rio Grande do Norte, where he collected data field, analyzed historical equipment and observing the behavior of faults and their impacts. The data were processed in commercial software reliability ReliaSoft BlockSim 9. The results were compared with a study conducted by the experts in the field in order to get the best maintenance strategy for the studied system. With the results obtained from the reliability analysis tools was possible to determine the availability of the centrifugal motor-fan and what will be its impact on the security of process units if it will fail. A new maintenance strategy was established to improve the reliability, availability, maintainability and decreased likelihood of Moto-Centrifugal Fan failures, it is a series of actions to promote the increased system reliability and consequent increase in cycle life of the asset. Thus, this strategy sets out preventive measures to reduce the probability of failure and mitigating aimed at minimizing the consequences.
