ABSTRACT Consumers around the world appreciate strawberries for their taste. They have low calories and high concentrations of soluble fibers, vitamin C and flavonoids. This paper verified the combined effect of O2, CO2, and N2O levels on ‘Oso Grande’ strawberries stored at 10° C, under controlled atmosphere (CA). Five different gas mixtures were used: 0.03 kPa CO2 + 20 kPa O2, 80 kPa N2O + 20 kPa O2, 90 kPa O2 + 10 kPa N2, 60 kPa O2 +40 kPa CO2, and 20 kPa O2 + 20 kPa CO2 + 60 kPa N2O. The lowest incidence of postharvest decay was observed with treatment20 kPa O2 + 20 kPa CO2 + 60 kPa N2O, followed by 80 kPa N2O +20 kPa O2 and 90 kPa O2 + 10 kPa N2. The treatment 60 kPa O2 + 40 kPa CO2 induced an increase in the production of acetaldehyde and ethanol, and these levels were considered inadequate for human consumption. The first factor, named senescence, displayed a positive correlation with soluble solids, luminosity, hue angle, firmness and incidence of decay. hpsThe second factor, named CA-induced injury, showedhps that total acidity correlated negatively with ethanol and acetaldehyde levels. Hiehpsrarchical cluster analysis indicated that strawberries stored underhps80 kPa N2O + 20 kPa O2hps for 14hps hpsdays more closely resembled the quality of fresh fruit at the moment of harvesthps. ‘Oso Grande’ strawberries stored at 10 ºC under 80 kPa N2O + 20 kPa O2 and 90 kPa O2 +10 kPa N2 were in better conditions, with no metabolic alterations, showing that these are the ideal storage conditions.

A Residência Médica (RM) está consagrada como a melhor forma de inserção de médicos na vida profissional e de capacitação numa especialidade. Observa-se uma discrepância entre o número de formandos candidatos à RM e o número de vagas credenciadas. Nesse contexto, alunos do quinto e sexto anos sacrificam a graduação médica durante os estágios curriculares para se dedicarem aos Cursos Preparatórios (CPs) para a RM. Buscou-se conhecer as expectativas dos alunos de Medicina em relação à RM, bem como suas opiniões sobre o surgimento dos CPs. Foram aplicados questionários com oito perguntas objetivas a 70,83% dos alunos do sétimo, oitavo e nono períodos da Faculdade de Medicina (FM). Todos afirmaram conhecer o método dos CPs; 76% pretendem se matricular; dos que não têm essa intenção, 63,17%, o principal motivo declarado é a falta de condições financeiras; 59,45% desaprovam o método atual de avaliação para a RM. Conclui-se que é necessário adequar os atuais métodos de ensino da FM ao modelo das avaliações da RM. Os critérios para o ingresso na RM poderiam ser ajustados, contemplando as habilidades práticas. As FMs devem, continuamente, disponibilizar material didático atualizado, moderno e acessível a todos os alunos.

Medical Residency (MR) is known as the best form for a doctor to start his professional life and to developing his skills in a specialty. There is however a discrepancy between the number of graduate/ candidates for Medical Residency and the number of vacancies. In this context, students in the 5th and 6th years of Medical School are sacrificing their medical graduation during their internships to dedicate themselves to Preparatory Courses (PCs) for the Medical Residency. This study sought to investigate the expectations of the students with regard to RM as well as/ their opinion about the creation of the PCs. 70.83% of the students of the 7th, 8th and 9th semesters/ of the Medical School (MS) answered questionnaires with eight objective questions. They all stated to know the PC method; 76%/ intended to enroll; out of those who did not intend on to enroll, 63.17% claim that the/ main reason/ is poor financial conditions. 59.45% disapproves the current method of admission tests for MR. In conclusion, it is necessary to adapt the current teaching methods of the medical school to the model of admission tests for MR. The criteria for admission to MR should be adjusted, also considering the practical skills. The medical schools should always make inexpensive, up-to-date and modern educational material available to the students.

No Brasil, há um déficit de vagas para Residência Médica (RM) e maior concorrência em determinadas especialidades ou regiões, propiciando o crescimento dos Cursos Preparatórios (CPs) para provas de RM. Os acadêmicos, cada vez mais, deixam atividades curriculares em segundo plano e se matriculam nesses cursinhos. Mediante um questionário dirigido aos candidatos do concurso de RM do Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF), realizou-se um estudo para avaliar a efetividade da preparação de alunos em CPs. A adesão foi de 74,7% dos 368 concorrentes, sendo que a maioria freqüentou CPs (72%). Não houve diferença significativa de aprovação entre os candidatos que se prepararam em CPs e os que não os freqüentaram. Já a média das notas dos candidatos que freqüentaram CPs foi 4,07 pontos maior (66,89 contra 62,82, p < 0,05). Conclui-se que, no modelo tradicional de avaliação, cuja prova teórica corresponde a 90% da nota final, a preparação dos alunos que freqüentaram CPs é mais eficaz, o que enaltece a memorização em detrimento de habilidades médicas. Nesse contexto, pode-se considerar o modelo 50/50, em que a prova prática corresponde a 50% da nota final, uma proposta adequada.

In Brazil there are not enough vacancies for Medical Residency (MR) and a very high competition for vacancies in certain specialties and regions. This favors the establishment of Preparatory Courses (PCs) for MR tests. Medical students have been increasingly neglecting their curricular activities for en rolling in these Preparatory Courses. For evaluating the effectiveness of these courses, a questionnaire was applied to the candidates for MR at the University Hospital of Federal University of Juiz de Fora. 74.7% from the 368 applicants agreed to participate in the study, most of which (72%) were frequenting PCs. There was no significant difference in the rate of approval among the candidates who had prepared themselves in PCs and those who did not. On the other hand, the average grade of the candidates that took PCs was 4.07 points higher (66.89 versus 62.82, p < 0.05). It is concluded that in the traditional evaluation model, whose theoretical test corresponds to 90% of the final grade, the preparation of the students who took PCs is more effective, valuing memorization above medical abilities. Thus, the 50/50 model, in which the practical test corresponds to 50% of the final grade, can be considered an adequate proposal.
