Densidade de estocagem em camarões da espécie Macrobrachium rosenbergii (De Man, 1879) na fase juvenil

Among the species of freshwater shrimp being cultivated, Macrobrachium rosenbergii stands out. Knowledge about the behavior of this species and the influence of certain factors on its development can help optimize management practices and minimize the likely impacts shrimp farming has on the environment and the animals themselves. The objective of this study was to characterize the species' behavior during early stages of development under different stocking densities over a 24-hour cycle. Ten day old postlarvae were transferred from the Jundiaí School of Agriculture (EAJ - Escola Agrícola de Jundiaí) in Macaíba (RN), Brazil to the Shrimp Behavior Laboratory (LSPR - Laboratório de Estudos do Comportamento do Camarão) at the Federal University of Rio Grande do Norte (UFRN), where they were weighed and measured. Eight aquaria with constant temperature, aeration and filtration, and subjected to a12 h light/12 h dark cycle were used for each experiment. Each aquarium also contained two shelters made of bricks and the water quality was monitored weekly. Behavioral observations were made at two densities: 25 individuals/m-² and 40 individuals/m-². The methods for recording behaviors were: behavioral sampling – enter and leave the shelter, exploring on the substrate, exploring in the water column, move away, attack, pursuit and cannibalism; scan sampling - inactivity, feeding, exploration, digging, swimming, cleaning and staying in the shelter. Observations were made during a 15 minute period/per aquarium at a frequency of 4 times daily, for 4 days/week, and over 4 weeks. Food was provided 2 times/day for each aquarium population, immediately before the 1st and 3rd observation periods. Our results demonstrate that at high density, there is an increased frequency of agonistic behavior; during the light phase, there is a greater frequency of behaviors that result in less exposure (inactivity, cleaning and staying in the shelter); during the dark phase, there is an increased frequency of behaviors that result in greater exposure (feeding, exploration, swimming and digging); at times of feed offer, there is an increased frequency of leaving the shelter, moving away, pursuit, feeding, exploration and swimming. At low density, the animals showed a lower frequency of agonistic behaviors, greater weight gain and higher growth rates, which indicates that this is a more favorable growing environment for cultivation and when applied, can generate better living conditions, favor survival rates and increase management success

Articulação entre saúde mental infanto-juvenil e atenção básica em Natal-RN: limites e possibilidades

In the case of Brazilian Psychiatric Reformation, mental health juvenile reveals itself as a great challenge, with major gaps in terms of needs, services and actions on mental illness in children and adolescents. This research is a qualitative study of descriptive and exploratory, having to analyze the actions and practices of mental health juvenile articulated between the Psychosocial Care Center juvenile (Caps i) and the basic care in Natal-RN, and specific, identify the limits and possibilities for an important precedent of the care network. After submission to the Research Ethics Committee (CEP) of the University Hospital Onofre Lopes (HUOL) of the Federal University of Rio Grande do Norte (UFRN) obtained approval contained in opinion number 777.067 / 2014. For the data collection, it was initially carried out a documentary research in the Municipal Health Department of Christmas about the phenomenon under study, and subsequently, applied semi-structured interviews with the subjects of the research, which were workers Caps i of Natal-RN. The analysis was woven as the thematic analysis technique, understood within the method of content analysis. The results and discussions were organized by categories and subcategories, namely: CATEGORY 1: Limits and weaknesses in the linkage between the Caps i and basic care, with the subcategories: 1.1 Lack of specialized services and devices articulators in network, 1.2 The diversity of situations in the demand juvenile assisted; CATEGORY 2: possibilities for an effective network, with the subcategory: 2.1 Intersectoral collaboration as a strategy for solving attention. The analysis revealed that the integration and coordination of mental health services juvenile and primary care in the city of Natal-RN, has incipient initiatives and/or inadequate for the resolvability intersectoral, where the devices of attention to health involved cannot establish bonds effective and long-lasting in the perspective of co-responsibility and sharing of care. On the other hand, it appears that the existing shares and practiced, configure an exercise in approximation to the dialog between mental health juvenile and basic care. It is highlighted that the shared care and the establishment of intersectoral collaboration within and outside of the health sector is possibility of facilitating the necessary dialog between the services and professionals involved, thus, enabling a better prospect of resolvability of the Network of Psychosocial Care for the youth in reality being investigated.

Atuação das equipes da atenção primária na identificação precoce do câncer infanto-juvenil

Identificar o conhecimento de profissionais da atenção primária sobre a identificação precoce do câncer infanto-juvenil e descrever o desempenho das equipes de saúde antes da realização de treinamentos para identificação precoce do câncer infanto-juvenil. Método: Os dados foram obtidos por um questionário e grupo focal com 30 profissionais de uma Unidade de Saúde da Família, e analisados por temas geradores. Resultados: Os profissionais possuem conhecimentos sobre a identificação do câncer infanto-juvenil, e, demandam conhecer mais sobre os sinais e sintomas para identificação precoce, e a prestação de uma assistência sistematizada. Conclusão: Torna-se fundamental estimular a qualificação dos profissionais da atenção primária para a identificação precoce e o fortalecimento de uma rede de assistência que proporcione atendimento integral e a redução no retardo do diagnóstico de câncer infanto-juvenil

Justiça juvenil: teoria e prática no sistema socioeducativo

Em um momento histórico de violações e ameaças aos direitos fundamentais de crianças e adolescentes, é preciso somar esforços na luta pela transformação das políticas voltadas para esses sujeitos. A ideologia que fundamenta a criminalização de adolescentes pobres e da periferia é a mesma que impõe a redução da idade penal e que autoriza e legitima as violências institucionais cometidas no sistema socioeducativo. Esta obra vem apresentar fundamentos teóricos e experiências práticas com vistas à desconstrução desses processos ideológicos e à defesa intransigente da proteção integral de crianças e adolescentes.
