“…Furthermore, the study desired a 95% confidence level, which is the most commonly used in the research literature. 23 The final sample size was 381, which was then proportionally distributed among the wards. The study subjects were chosen using a systematic random sampling procedure from the total number of patients.…”

Introduction This study aims at assessing the level of patient communication satisfaction and its impact on patient adherence among public hospitals in Ethiopia. Methods The study employed a cross-sectional design. Data were obtained using Communication Assessment Tool (CAT) and the Adherence to Refills and Medication Scale (ARMS) administered to 381 patients asking them to evaluate satisfaction with physician-patient communication and report their level of adherence respectively. Both descriptive and inferential statistics were computed. Accordingly, the study used correlation, independent samples t -test, one-way ANOVA, and linear regression to show causal relationships among factors in physician-patient communication and their effect on adherence. Results The findings revealed that the total mean score for communication satisfaction was M = 2.69, showing that the majority of participants were dissatisfied with the physician-patient communication. Further, age and frequency of visits were significantly associated with communication satisfaction, while sex, place of residence, employment, educational level, and marital status failed to produce a systematic effect. The correlation between patient satisfaction with communication scores on the CAT questionnaire was significantly correlated with pharmaceutical adherence (ARMS score) (r = 0.316, p < 0.001), indicating that when patients were satisfied with communication, the level of adherence increased. The regression coefficient also showed that positive relationship was found between communication satisfaction and adherence (b = 1.85, t = 9.759, p < 0.05), indicating that with better quality of communication, the level of adherence also increased. Conclusion The majority of participants were found to be dissatisfied with the physician-patient communication. The more satisfied the patient is with communication the better their adherence.

“…Tables 8 and 9 show the B50% life as per computed using the Quick Calculation Pad from Weibull++ Software. The Two-sided Confidence Level of 95% was considered, which is the measure of the imprecision of the true effect size in the population of interest estimated in the study population (Patino and Ferreira, 2015).…”

In this paper, the forced outage data from the Brazilian National Interconnected System (SIN) is provided and the statistics from the thermal power plants are computed. The SIN is characterized by a marked seasonality in electricity supply. In addition, the expansion pattern of the Brazilian electric sector shows signs of exhaustion, and the demand for flexible thermal power plants, based on availability, requires outage management as a reliability-centered maintenance (RCM) strategy. In this work, the non-parametric Kruskal-Wallis test and Dunn’s pairwise-comparisons were chosen for evaluating the mean forced outage duration (MFOD) and the forced outage factor (FOF) using the data from the national electricity system operator (ONS) with R Software. The distribution fitting was provided using Weibull++ software from Reliasoft. Based on the MFOD and unit failure rate data, the FOF for Brazilian thermal power plants is 3.33% with a 90% probability and 95% confidence level. Finally, Brazilian thermal power plants were benchmarked against North American power plants.

“…Outra possível causa do receio das gestantes a respeito da imunização pode relacionar-se aos eventos adversos pósvacinação (EAPV) contra a influenza. Vale destacar que as vacinas são importantes instrumentos para promover a imunização de um indivíduo e proteção da comunidade, proporcionando a redução da disseminação de agentes infecciosos, reduzindo assim, as consequências geradas pelas doenças imunopreveníveis (17) . É notório que, assim como outros medicamentos, as vacinas não estão livres de ocasionar eventos adversos, comumente conhecido como "efeitos colaterais" pela população em geral.…”

Objetivo: Analisar a cobertura vacinal contra a influenza em gestantes na região Sudeste do Brasil, nos anos de 2010 a 2020. Métodos: Estudo ecológico, de série temporal, realizado com dados do Sistema de Informação do Programa Nacional de Imunizações (SI-PNI), referentes aos registros de doses da vacina contra influenza em gestantes no estado de Minas Gerais. Resultados: A cobertura vacinal adequada foi alcançada em apenas quatro dos 11 anos estudados, variando de 49,75% em 2011 a 88,5% em 2015. No ano de 2020 foi alcançado 80,82%. Possíveis determinantes são discutidos em uma perspectiva ampliada, que pode subsidiar planejamento de ações em todo o país. Conclusão: A cobertura vacinal contra Influenza nas gestantes apresentou, em sua maior parte, uma tendência estacionária, apontando para a possível necessidade de educação permanente dos profissionais de saúde envolvidos no pré-natal, qualificação de suas ações na área de educação em saúde para esclarecer dúvidas das gestantes sobre a temática.
