Contributions to the ontology of aging, the sensitive indicators of rehabilitation nursing care, in terms of self-care, in people with respiratory disorders

With the increase in the average life expectancy, the appearance of chronic diseases and, in particular, in the respiratory forum and its disadvantages in the autonomy and self-care of patients, brought an important paradigm for health care and, in particular, rehabilitation nursing, with implications for the development of ontologies of aging. Thus, it is imperative to systematize them in scientifically measurable indicators to demonstrate the benefit that rehabilitation nursing brings to improve patients' quality of life, thus ensuring excellence. Each area of scientific health should contribute to the construction of aging ontology. Objective: to identify indicators sensitive to nursing care of rehabilitation, in terms of self-care, in relation to those with respiratory pathology, to be integrated into the ontology of aging. Methods: A systematic review of the literature was performed using the EBSCO (full-text MEDLINE, CINAHL, Full-Text Plus, British Nursing Index), using the PI [C] O method with 6 emergent articles. Results: A total of 20 indicators were identified, including: Ability to perform activities, increase physical and functional independence, symptom management, reduction of complications, increase in quality of life, which can be allocated as a proposal for classes of the aging ontology. Conclusion: Knowledge of indicators sensitive to nursing care recognition of the importance of rehabilitation nursing in increasing self-care and autonomy for people with respiratory pathology, and research in this area is fundamental for its effectiveness and efficiency, and its integration in the ontologies of aging is fundamental

Hypernetworks: capturing the multilayers of cooperative and competitive interactions in soccer

Hypernetwork theory brings together the micro–meso–macro levels of analysis of interaction-based complex systems (Johnson, 2013; Boccaletti et al., 2014). This study considers team synergies (Araújo and Davids, 2016), where teams and athletes are co-evolving subsystems that self-organize into new structures and behaviors. The emergent couplings of players’ movements have been studied, considering mostly the distance between a player and the immediate opponent (e.g., Headrick et al., 2012), and other interpersonal distance measures (Passos et al., 2011; Fonseca et al., 2013). Such emergent interpersonal behavior of soccer teams can be captured by multilevel hypernetworks approach that considers and represents simultaneously the minimal structure unit of a match (called simplex). More stable structures are called backcloth. The backcloth structure that represents soccer matches is not limited to the binary relations (2-ary) studied successfully by social networks analysis (SNA) but can consider also n-ary relations with n > 2. These simplices most of the times composed of players from both teams (e.g., 1 vs. 1, 2 vs. 1, 1 vs. 2, 2 vs. 2) and the goals. In a higher level of representation, it is also possible to represent the events associated, like the interactions between players and sets of players that could cause changes in the backcloth structure (aggregations and disaggregation of simplices). The main goal of this study was to capture the dynamics of the interactions between team players at different scales of analysis (micro—meso—macro), either from the same team (cooperative) or from opponent team players (competitive).info:eu-repo/semantics/publishedVersio

A proposal of sensitive indicators of the rehabilitation nursing care of people in the surgical process, to be included in the ontology of aging

Given the complex surgical scenario observed today, it is necessary to change the urgent definition of a specific ontology, especially in terms of aging. The interventions of the Specialist Nurse in Rehabilitation Nursing to the person in the surgical process are primordial for the maintenance of the functional capacities, prevention of complications and impediment of incapacities. However, it is necessary to provide individualized and fostered care in a practice of excellence, and the consequent organized reading of records of an aging ontology for decision making on rehabilitation indicators. Method: a systematic review of the literature was carried out using the EBSCO host (MEDLINE with Full Text, CINAHL Plus with Full Text and MedicLatina), using the PI [C] O method, and 11 articles were selected. Results: 41 indicators were identified to be included in the ontology classes of aging: pain control, patient and family education, support and communication, reduction of postoperative complications, gain of functionality, restoration of physical function, mobility, multidisciplinary intervention and the frequency of interventions. Conclusion: it is considered that it was imperative to identify sensitive indicators for rehabilitation nursing care, based on scientific evidence and thus provide an opportunity for nurses to reflect on their daily practices and conduct their actions towards excellence in care, to propose a set of 41 classes internationally on the ontology of aging

Características do enfermeiro supervisor: construções elaboradas pelos estudantes de 1º ciclo em Enfermagem

Introdução: A supervisão clínica em enfermagem constitui uma realidade no ensino da enfermagem em Portugal. O seu âmago não se restringe à transmissão de conhecimentos práticos. O enfermeiro supervisor deve possuir competências clínicas - técnicas, científicas e relacionais - a par da capacidade de discutir, questionar e fazer reflectir o estudante no desenvolvimento da acção (Ketola, 2009). Em simultâneo, deve possuir competências pessoais facilitadoras de uma relação efectiva com o estudante, como sejam, simpatia, empatia, assertividade, respeito, entre outras. Objectivos: Apreender as representações sociais das características do enfermeiro supervisor clínico, elaboradas por estudantes. Explorar a dimensão estrutural das representações sociais do enfermeiro supervisor clínico, na perspectiva dos estudantes. Identificar o campo das representações sociais de enfermeiro supervisor clínico, na perspectiva dos estudantes. Metodologia: Estudo exploratório, cuja amostra é constituída por 74 estudantes 4º ano, 1º ciclo de Enfermagem. A recolha dos dados foi feita em Fevereiro, através de questionário com questões que visavam a caracterização sócio-demográfica e um estímulo indutor (características do enfermeiro supervisor). Foram cumpridos procedimentos ético-legais, em conformidade com a comissão de ética da Área da Saúde e Bem-Estar da Universidade de Évora. Os dados foram categorizados recorrendo ao Microsoft Office Word e processados nos softwares Evoc e SIMI que forneceram estrutura das representações sociais e força da relação entre elementos. Resultados: A predominância dos respondentes era estudantes do sexo feminino, com idade média de 24,6 anos. As palavras evocadas pelos estudantes foram 359, apurando-se 47 palavras diferentes. As representações sociais de enfermeiro supervisor clínico têm a seguinte estrutura: - o núcleo central, fornece os elementos mais consensuais, é constituído por: acessível, competência, conhecimento, disponível, empatia, experiência, honestidade e imparcialidade; - a segunda periferia, fornece elementos menos consensuais com maior carga individual dos elementos do grupo em estudo, é constituída por: amigo, colaborador, cordial, directo e empenho. A árvore máxima que derivou da análise de similitude comprovou a centralidade dos elementos disponível, conhecimento e empatia. Mostrou, também, que existe uma relação forte entre os elementos disponível e cordial e uma relação moderada entre a maioria dos restantes elementos com centralidade. Conclusão: As representações sociais de enfermeiro supervisor, construídas pelos estudantes, assentam em duas competências básicas: competências de experiência profissional, alimentadas pelo conhecimento, e competências pessoais relacionadas com o carácter do enfermeiro. Assim, os estudantes têm no seu imaginário que o enfermeiro supervisor deve ter experiência e conhecimentos, deve ser acessível, compreensivo, disponível, empático, honesto e imparcial. Pearson (2009) diz que as experiências clínicas são condicionadas pela relação estabelecida entre enfermeiro supervisor e estudante. O enfermeiro supervisor deve ser capaz de questionar a sua prática clínica e estratégias utilizadas no sentido de possibilitar ao estudante compreensão dos ambientes de cuidados (Fernandes, 2007)

Representações sociais de enfermeiro supervisor elaboradas por estudantes de enfermagem

Supervision and learning must be guided and accompanied by expert nurses in the clinical area. The nurse supervisor is required, in addition to clinical skills, ability to discuss, to question and to reflect with the student (Ketola, 2009). Objectives: Identify the social representations (SR) of the clinical nurse supervisor characteristics, built by students. Analyze the relationship between the components of SR nursing clinical supervisor in prospective students. Methodology: Exploratory study, the sample consisted of 74 students of 4th year, 1st cycle of Nursing. Data collection was conducted through a questionnaire. We met the ethical and legal procedures. The data were categorized using the Microsoft Office Word and processed in software Evoc and SIMI. Results: There was a predominance of female respondents, with a mean age of 24.6 years. Of the 359 words evoked, 47 is ascertained different. The SR nursing clinical supervisor have the following structure: the more consensual elements - core - were accessible, competence, knowledge, available, empathy, experience, honesty and impartiality. The elements less consensus second-periphery - were: friend, collaborator, friendly, direct and commitment. The similarity analysis to prove the centrality of the elements available, knowledge and empathy and showed that there is a strong relationship between the elements available, friendly and a moderate relationship between the majority of the remaining elements with centrality. Conclusion: The nursing supervisor RS, developed by students, are structured skills of professional experience, supported by knowledge, and skills related to the personal nature of the nurse. Thus, the nurse supervisor, in the minds of students, must have experience and knowledge should be accessible, comprehensive, available, empathetic, honest and impartial. Clinical experiences are conditioned by the relationship between supervisor and student nurses (Cunha et al, 2010; Pearson, 2009)
