Critical Education in Community Health Literacy for Brazilian Nurses: A Course Evaluation

This article presents an immediate evaluation of a professional development course in community health literacy for Brazilian nurses. An evaluation based on an applied thematic analysis of the accounts of 63 attendees in three Brazilian cities (January 2020) was guided by the following themes: (a) expansion of understanding about community health literacy as a pillar for planning and providing health care; (b) encouragement of innovation in research and/or practice; and (c) plans to incorporate the information shared in the course into professional projects. The evaluation disclosed the complexity of social contexts for health literacy, which is intertwined with ethnocultural diversity and deep socioeconomic disparities, such as restricted access to essential public health services for socially deprived and vulnerable individuals. Expanded understanding about community health literacy is a pillar for care planning and delivery, as well as innovation in research and practice projects. Participants’ evaluations revealed ideas to improve nurses’ practice in promoting community health literacy and empowerment, as well as quality of life and social well-being. Future knowledge dissemination may impact nurses’ clinical practice and management actions, bringing changes in various areas of practice to redesign more socially inclusive actions for clientele.

Graphene oxide and a GO/ZnO nanocomposite as catalysts for epoxy ring-opening of epoxidized soybean fatty acids methyl esters

In this work, the grapheme oxide (GO) and GO/ZnO nanocomposite were successfully obtained from the oxidation of graphite and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). In the GO/ZnO nanocomposite, the GO sheets were coated with aggregated ZnO nanoneedles with ca. 20 nm of diameter. The obtained materials were used as heterogeneous catalysts for acetylation of Soybean Fatty Acids Methyl Esters (FAME), promoting the epoxy ring-opening using acetic anhydride. The epoxy ring was almost completely opened in the presence of GO or GO/ZnO nanocomposites, with conversion rates up to 99% and selectivity of ca. 90%, and partially opened using only ZnO. The GO/Zn and GO catalysts were reused three times with conversion rates of ca. 85 and 74%, respectively

Electrical switching of a chiral lasing from polariton condensate in a Rashba-Dresselhaus regime

Efficient optical classical and quantum information processing imposes on light novel requirements: chirality with low threshold non-linearities. In this work we demonstrate a chiral lasing from an optical modes due to emerging photonic Rashba-Dresselhaus spin-orbit coupling (SOC). For this purpose we developed a new electrically tunable device based on an optical cavity filled with birefringent liquid crystal (LC) and perovskite crystals. Our novel method for the growth of single crystals of CsPbBr$_3$ inorganic perovskite in polymer templates allows us to reach a strong light-matter coupling regime between perovskite excitons and cavity modes, and induce polariton condensation. The sensitivity of the LC to external electric fields lets us to tune the condensate energy in situ and induce synthetic SOC. This shapes the condensate between a single linearly polarized or two circularly polarized separated in momentum, emitting coherent light. The difference in the condensation thresholds between the two SOC regimes can be used to switch on and off the chiral condensate emission with a voltage.Comment: 8 pages, 5 figure

Avaliação da desativação das zeólitas HY e HZSM-5 por gasóleo de vácuo leve usando teste de microatividade e termogravimetria

Este trabalho teve como objetivo analisar a acidez das zeólitas ácidas HY e HZSM-5, e avaliar a sua desativação por formação de coque. Os catalisadores utilizados foram as zeólitas NH4ZSM-5 e NH4Y obtidas comercialmente, ambas do fabricante Zeolyst. Estas zeólitas foram calcinadas com intuito de aumentar sua acidez, obtendo-se as respectivas formas protônicas. Os materiais foram caracterizados por termogravimetria (TG/DTG), adsorção de N2 (método BET) e determinação da acidez. Através da adsorção e da termodessorção da base n-butilamina, foram determinadas as forças ácidas de cada sítio ácido para ambos os materiais. A zeólita HY apresentou uma acidez total superior à da zeólita HZSM-5. Foi realizado o teste catalítico com gasóleo leve de vácuo com a finalidade de desativar os catalisadores, na qual foram analisados os resíduos carbonáceos formados em suas estruturas. Através das curvas TG/DTG foram verificadas duas perdas de massa na zeólita HZSM-5 desativada, apresentando tipicamente coque com caráter tanto alifático como aromático, enquanto que a zeólita HY apresentou tipicamente coque alifático

Communication in health practices: integrative literature review

Objectivethis study aims to describe the main thematic axes explored in the communication field in health practices in the scenarios of the Unified Health System (SUS). Methodintegrative literature review conducted by means of search for articles in the databases Latin American Literature on Health Sciences (LILACS), International Literature on Health Sciences (MedLine), and Science Direct, using the descriptors: health communication or communication. A crossing of the descriptors communication and health education was provided. Resultfour themes were constructed: 1) communication to establish relationships between health professionals and users; 2) (in)communication: barriers to the communicative act, 3) communication and health professional education; and 4) communicative health models: search for the dialogic model. Conclusionby understanding dialogic communication, which must be observed in communication, the new requirements posed by the legalization of SUS have shown weaknesses of the single-line and vertical communication model and the need to provide health professionals, since the undergraduate course, with knowledge that enable dialogic communication practices. The challenge of reflective and participatory experiences in the various health care settings still remains, in order to promote a sharing of knowledge that leads to understanding between the interlocutors involved in the communicative act.Objetivoeste artigo tem por objetivo descrever os principais eixos temáticos explorados no campo da comunicação nas práticas em saúde nos cenários do Sistema Único de Saúde (SUS).

Conclusãoa partir do entendimento da comunicação dialógica, que deve estar presente na comunicação, as novas demandas da legalização do SUS vêm mostrando fragilidades do modelo unilinear e verticalizado de comunicação e a necessidade de instrumentalizar os profissionais da saúde, desde a graduação, com saberes que proporcionem práticas comunicativas dialógicas. Persiste o desafio de vivências reflexivas e participativas nos vários cenários de assistência à saúde, de forma a promover um compartilhamento de saberes que conduza ao entendimento entre os interlocutores envolvidos no ato comunicativo.Universidade Federal de PernambucoUniversidade Federal de Pernambuco Departamento de FonoaudiologiaUniversidade Federal de São Paulo (UNIFESP) Centro de Desenvolvimento do Ensino Superior em SaúdeUniversidade Federal de Pernambuco Departamento de EnfermagemUNIFESP, Centro de Desenvolvimento do Ensino Superior em SaúdeSciEL

Tongue interface based on surface EMG signals of suprahyoid muscles

The research described herein was undertaken to develop and test a novel tongue interface based on classification of tongue motions from the surface electromyography (EMG) signals of the suprahyoid muscles detected at the underside of the jaw. The EMG signals are measured via 22 active surface electrodes mounted onto a special flexible boomerang-shaped base. Because of the sensor’s shape and flexibility, it can adapt to the underjaw skin contour. Tongue motion classification was achieved using a support vector machine (SVM) algorithm for pattern recognition where the root mean square (RMS) features and cepstrum coefficients (CC) features of the EMG signals were analyzed. The effectiveness of the approach was verified with a test for the classification of six tongue motions conducted with a group of five healthy adult volunteer subjects who had normal motor tongue functions. Results showed that the system classified all six tongue motions with high accuracy of 95.1 ± 1.9 %. The proposed method for control of assistive devices was evaluated using a test in which a computer simulation model of an electric wheelchair was controlled using six tongue motions. This interface system, which weighs only 13.6 g and which has a simple appearance, requires no installation of any sensor into the mouth cavity. Therefore, it does not hinder user activities such as swallowing, chewing, or talking. The number of tongue motions is sufficient for the control of most assistive devices
