Biopolymer-based materials have been of particular interest as alternatives to synthetic polymers due to their low toxicity, biodegradability and biocompatibility. Among them, chitosan is one of the most studied ones and has recently been investigated for the application as solid state polymer electrolytes. Furthermore, it can serve as a host for luminescent species such as rare earth ions, opening up the possibility of combined electro-optical functionality, of particular interest for electroluminescent devices. In this study, we perform a fundamental, initial, investigation of chitosan based luminescent materials doped with EuIII and LiI triflate salts, from the structural, photophysical and conducting points of view. Because the host presents a broad emission band in the blue to green, while EuIII emits in the red, fine-tuning of emission colour and/or generation of white light is proven possible, by proper combination of optimized composition and excitation scheme. Europium lifetimes (5D0) are in the range 270-350 µs and quantum yields are up to 2%. Although LiI does not interfere with the luminescent properties, it grants ion-conducting properties to the material suggesting that a combination of both properties could be useful in the development of electro-luminescent devices.

Las directrices nacionales e internacionales destacan prácticas de enfermería centradas en la familia. Realizado estudio cuantitativo, con el objetivo de caracterizar las actitudes de los enfermeros que trabajan en la Atención Primaria de Salud en Administración Regional de Salud Center, en la importancia de involucrar a la familia en los cuidados de enfermería. Inquirió una muestra de 871 profesionales de enfermería de los centros de salud de la región central de Portugal, con la versión portugueses de la escala “Importancia de las familias en el cuidado de enfermería: enfermeras actitudes (FINC-NA)” (Benzei et al., 2008), validada por Oliveira et al. (2009) e Oliveira et al. ( 2011). Los resultados obtenidos, con puntuaciones promedio altos sobre las dimensiones de la función: familia de enfermería (76.48), familia: socio en el diálogo y la acción para hacer frente (73,33) y baja dimensión familiar: carga (21,60), destacar que enfermeras tienen actitudes de apoyo hacia la familia está relacionada con la formación que tienen experiencia profesional en el tiempo, la unidad en la que trabajan y el método de organización de la atención. Concluimos que los enfermeros en Administración Regional de Salud Center tienen actitudes cara de apoyo a la familia, que es un criterio importante para la calidad de la atención que ofrecen en la Atención Primaria de Salud.

As orientações nacionais e internacionais evidenciam as práticas de enfermagem centradas na família. Realizámos um estudo quantitativo, com objetivo de caraterizar as atitudes dos enfermeiros que trabalham em Cuidados de Saúde Primários, na Administração Regional de Saúde do Centro, relativamente à importância de envolver a família nos cuidados de enfermagem. Inquirimos uma amostra de 871 enfermeiros de centros de saúde da região centro de Portugal, com a versão Portuguesa da Escala Families Importance in Nursing Care - Nurses Attitudes (FINC-NA), (Benzei et al., 2008), validada por Oliveira et al. (2009; 2011). Os resultados obtidos, com scores médios elevados nas dimensões Família: recurso nos cuidados de enfermagem (76.48 pontos) e Família: parceiro dialogante e recurso de coping (73.33 pontos) e baixos na dimensão Família: fardo (21.60 pontos), evidenciam que os enfermeiros possuem atitudes de suporte em relação à família, estando relacionadas com a formação que possuem, o tempo de experiência profissional, a unidade onde trabalham e o método de organização dos cuidados. Concluímos que os enfermeiros da Administração Regional de Saúde do Centro possuem atitudes de suporte face à família, o que constitui um critério importante para a qualidade dos cuidados que prestam em contexto de Cuidados de Saúde Primários.

National and international guidelines on show that nursing practices are focused on families. We have conducted a quantitative study, with the objective of characterizing the attitudes of nurses working in primary health care in regional health centers, on the importance of involving the family in nursing care. We studied a sample of 871 nurses at health centers in the central region of Portugal, using the Portuguese version of the Families Importance in Nursing Care - Nurses’ Attitudes scale (FINC-NA)( Benzei et al., 2008), validated by Oliveira et al. (2009; 2011). The results showed high average scores on the following dimensions: Family: use of nursing care (76.48) and Family: partner in the dialogue and coping resources (73.33), and low scores on Family: burden (21.60). These results highlight that nurses have supportive attitudes towards families, and these are related to training, length of professional experience, the unit where they work, and the method of organization of care. We conclude that nurses in regional health centers have supportive attitudes towards families, which is an important criterion for the quality of care they provide in the context of primary health care.
