Objective: Recognizing the concerns of primiparous women about labor and birth, the nurse identify
actions to mitigating the feelings of women. Method: this was a descriptive, exploratory research,
qualitative in nature, with six primiparous women rooming at the University Hospital Antonio Pedro
through semistructured interviews and analyzed with the principles of thematic analysis, after approval by
the Ethics Committee of the University Hospital Antonio Pedro, under nº 218 283. Results: in the data
analysis, the results showed their feelings and expectations regarding their relationship with labor and
birth, such as fear, insecurity and anxiety. However, the presence of a companion proved to be important
for inhibition of these feelings. Conclusion: the health professional should facilitate and promote care to
the mother, with a resulting assistance of a trust and bond
Nesta contribuição, apresentamos um tema avançado de grande relevância na Física: a quebra espontânea de simetria – fundamental para o chamado Mecanismo de Higgs – numa abordagem adequada ao ensino médio. O modelo matemático da quebra de simetria é abordado a partir da analogia entre os osciladores harmônico simples e anarmônico. Na sequência, discutimos como a massa física do bóson de Higgs surge a partir da oscilação da coordenada oscilatória de Higgs, aqui desempenhando o papel do campo de Higgs. Também propomos o uso de simulação computacional, utilizando o software Modellus , para estudar a energia dos osciladores. O objetivo de propor a simulação é tornar a aprendizagem mais eficiente e aumentar o protagonismo do aluno.
