Prevalence of recurrent wheezing and its risk factors

Objective: analyze the prevalence of recurrent wheezing and its risk factors. Method: systematic literature review, guided by the research question “what is the prevalence of recurrent wheezing and its risk factors?”. The search was performed in the databases MedLine and LILACS, in April and May 2013. The inclusion criteria were: scientific study, fully available, published between 2002 and 2013, with free access. Results: wheezing presents a higher prevalence in developing countries, possibly due to poor socioeconomic conditions. Among its risk factors, we find heredity, mother’s education level, attendance of day nursery, smoking during pregnancy, breastfeeding for < 3 months, animals in the household of children, among others. Conclusion: in Latin America, the prevalence of wheezing shows to be high and the use of non-standardized instruments hampers its treatment.

O pequeno leitor e o processo de mediação de leitura literária

This article discusses literary education from early childhood, understanding early childhood as the nursery period from zero to five years. This paper aims to make some observations about the teaching and learning of reading, their relationships with children’s literature, and the formation of literary taste. It also discusses the mediating role of the teacher in the process of literary education, and the school as a space in which this mediation should occur.

Influência de procedimentos educativos sobre os conceitos de berçários

The duality care-education is an aspect to be considered in the routine of childhood education institutions that have a nursery. The concepts of professionals who work in the nursery interfere with the developed practice, and require great concern regarding the continuing education. The objective of this study was to verify the effects of educational procedures on the concepts related to functions and benefi ts of the nursery for the child – from the professionals who work in a childhood education institution. These professionals were teachers and development assistants from municipal nurseries of Marília, interviewed four times – initially, after each of the two rearing procedures, and six months after the procedures. These procedures consisted of educational workshops, once a week, for one month, and 15 hours of supervised practices in the nursery. Both practices focused on the activities and their benefi ts to the child’s development. We found that the educators’ knowledge comes from common sense, and that educational workshops provided changes on their information levels, which were strengthened by supervised practice. The analysis indicates that the initial and continuing education of professionals need to consider specifi c aspects of child development, so more adequate concepts are built.

Relações de gênero na escola: feminilidade e masculinidade na Educação Infantil

The text aims to refl ect about masculinity and femininity in children’s education, an almost entirely feminine environment, bringing fi ndings of a study that investigated the social relations of gender in this level of teaching in a school where a man worked as a teacher. Data was composed by observations of pedagogical practices of a woman teacher and a man teacher of Early Childhood Education. After that, those teachers, the pedagogical coordinator, the headmaster and a nursery worker were interviewed. Based on theoretical contributions about culture and gender, the paper shows that the masculine and the feminine identities and social roles for both sexes, historically, are human constructions that can be modifi ed, especially at school.

ONTOGENETIC DEVELOPMENT OF SENSORY STRUCTURES ON THE ANTENNULES AND ANTENNAE OF THE GIANT RIVER PRAWN MACROBRACHIUM ROSENBERGII (DE MAN)

In this study the occurrence of sensory structures on the antennules and antennae of the giant river prawn Macrobrachium rosenbergii (De Man) during postembryonic ontogenetic development were examined. Larvae and postlarvae were obtained from hatchery recirculating tanks, juveniles from indoor nursery tanks, and adults from earthen grow-out ponds. The animals were fixed with Karnovsky fixative and dissected. Antennules and antennae were removed, metal-coated, and photodocumented using a scanning electron microscope. The antennules have aesthetascs and simple plumose and pappose setae; the antennae have simple, plumose and pappose setae. These structures increase in density, covered surface, and distribution during ontogeny and should be related to chemoreception and mechanoreception. The antennular statocyst that appears during larval stage VII of the giant river prawn has an array of sensory structures that enable the perception of chemical and tactile stimuli beginning with its early life stages. The ontogenetic changes observed allow an inference that initial-stage larvae, advance-stage larvae, juveniles, and adults have different capacities to exploit the environment.

Superação da dormência de sementes de Tucum (Astrocaryum huaimi Mart.)

The objective of this study was to evaluate the effect of immersion for varying periods in different concentrations of gibberellic acid and separate methods of scarification on the germination of seeds tucum. In the first trial, testing different soaking periods (24 and 48 hours), different forms of soaking (fast and slow) and different concentrations of gibberellic acid (0, 100 and 200 mg L-(1)) compared to the control (water) under completely randomized design in a factorial 2x2x3. The second experiment evaluated the different scarification treatments being: physical (seed coat removal in the hilar region with the aid of a scalpel), chemical (sulfuric acid 98 PA for 2:04 minutes) and thermal (hot water at approximately 98 degrees C and cold water at about 2 degrees C for 4 minutes). In the first trial were evaluated % of contaminated seeds (seeds infected by microorganisms) and hard seeds (who did not start the germination process, but not soiled), and in the second we assessed germination percentage (%) every two days for three months; germination Speed Index (GSI), time to occurrence of 50 % germination (T50) and Emergency Speed Index (ESI). The use of gibberellic acid was ineffective in promoting germination of Tucum (Astrocaryum Huaimi Mart.). Scarification treatments were effective in promoting germination and emergence of seedlings in the nursery and the most efficient physical removal scarification of the seed coat in the hilar region with the highest percentage of germination.
