The autonomous vehicle(AV)technology has the potential to significantly improve safety and efficiency of the transportation and logistics ***-scale AV testing is limited by time,space,and cost,while simulation-based testing often lacks the necessary accuracy of AV and environmental *** recent years,several initiatives have emerged to test autonomous software and hardware on scaled *** systematic literature review provides an overview of the literature surrounding small-scale self-driving cars,summarizing the current autonomous platforms deployed and focusing on the software and hardware developments in this *** studies published in English-language journals or conference papers that present small-scale testing of self-driving cars were *** of Science,Scopus,Springer Link,Wiley,ACM Digital Library,and TRID databases were used for the literature *** systematic literature search found 38 eligible *** gaps in the reviewed papers were identified to provide guidance for future *** key takeaway emerging from this manuscript are:(i)there is a need to improve the models and neural network architectures used in autonomous driving systems,as most papers present only preliminary results;(ii)increasing datasets and sharing databases can help in developing more reliable control policies and reducing bias and variance in the training process;(iii)small-scaled vehicles to ensure safety is a major benefit,and incorporating data about unsafe driving behaviors and infrastructure problems can improve the accuracy of predictive models.

Objective: To understand, based on the life narratives of refugee women, food and nutritional security. Method: Qualitative, descriptive, exploratory study, Narratives of life method, by Daniel Bertaux. Conducted with 11 participants, refugee women residing in the state of Rio de Janeiro, Brazil. Results: The meanings and feelings evidenced in the life narratives of refugee women expressed the insecurities and weaknesses with food in the resettlement. Final Considerations: Given the meanings and feelings regarding food in the refuge, it is expected that the present study will contribute to the elaboration of new action plans and intersectoral public policies of agile action to meet the demands of the refugee population, in the attempt to mitigate starvation, poverty, social differences and the compromised health status of the refugee population.

Health 2015年第10期7卷 1235-1242页

作者： Fábia Barbosa de Andrade Tainara Lorena dos Santos Ferreira Tiago Jose Barbosa de Andrade Jéssica Isabelle dos Santos Dutra Dídia de Oliveira pereira brenda Kalyny Silva brenda Kalyny Silva Ingrid Katianne Marques Araújo Faculty of Health Sciences of Trairi(FACISA) Federal University of Rio Grande do Norte(UFRN)Santa CruzBrazil University Center of Joao Pessoa(UNIPe) Joao PessoaBrazil

Objective: The present work aims to evaluate the impact of the activities of nursing consultations on health conditions of children served in Clínica de Enfermagem Salvando Vidas com Educa??o. Methods: This is an exploratory, descriptive study with a quantitative approach, realized from January through December 2012, at the Clínica de Enfermagem (Nursing Clinic), in the Santa Cruz County, Rio Grande do Norte’s countryside, Brazil. Results: The obtained results showed a significant correlation between the type of pathology and final treatment proven by the value of p = 0.000;as for assessed 60%, more than half were discharged;the most prevalent diseases were the association between cutaneous and gastric with 11% who were discharged and, lastly, the association between gastric and respiratory with 7% discharged. Conclusion: Thus, the activities developed by the project are not restricted to the examination during the nursing consultation, since educational activities are planned from the data obtained in those consultations.
