Meneguel Joice Fabiola,Guinsburg Ruth,Miyoshi Milton Harumi,Peres Clovis de Araújo
Revista Brasileira de Ginecologia e Obstetrícia , 2002,
Abstract: Objetivo: avaliar se ciclos múltiplos de corticosteróide antenatal (CEA) s o mais efetivos, em rela o ao ciclo único, na redu o da morbimortalidade de prematuros. Métodos: estudo retrospectivo envolvendo 184 neonatos com idade gestacional inferior a 34 semanas, nascidos em hospital de nível terciário de S o Paulo no período de janeiro de 1988 a dezembro de 1998. Os pacientes foram divididos conforme o tratamento em: ciclo único (n=135): se a gestante recebeu um ciclo completo do CEA (2 doses de betametasona ou 4 doses de dexametasona, entre 24 horas e 7 dias do parto) e ciclos múltiplos (n=49): se a gestante foi tratada com dois ou mais ciclos completos. Foram comparados entre os dois grupos do estudo: síndrome do desconforto respiratório (SDR), mortalidade intra-hospitalar e morbidade neonatal combinada (ocorrência de um ou mais: SDR, hemorragia periintraventricular, displasia broncopulmonar, enterocolite necrosante, sepse ou óbito intra-hospitalar). Os dados maternos e neonatais foram comparados pelo teste t de Student ou Mann-Whitney para as variáveis numéricas e pelo chi2 ou exato de Fisher, com cálculo das "odds ratio" e seu intervalo de confian a, para as variáveis categóricas. Resultados: n o foi demonstrada diferen a significante na evolu o dos neonatos do grupo ciclo único em rela o ao múltiplo quanto à ocorrência de SDR (ciclo único: 22% e ciclo múltiplo: 18%), mortalidade intra-hospitalar (único 18% e múltiplo 12%) e morbidade neonatal combinada (único 62% e múltiplo 63%). Conclus es: o uso de ciclos múltiplos de CEA n o diminuiu a morbimortalidade de prematuros. Esse estudo refor a a recomenda o atual da utiliza o de ciclo único de corticosteróide para a matura o fetal em gestantes em trabalho de parto prematuro.

International Journal of Morphology , 2007,
Abstract: Las técnicas de fijación, conservación y preservación, con fines didácticos y académicos, buscan la manera de encontrar sustancias que mantengan, dentro de lo posible, el estado natural del cuerpo u órganos, penetrando en los tejidos y permitiendo un fácil montaje, proporcionando información detallada y una visión tridimensional de las estructuras. Se planteó como objetivo del trabajo la visualización de la angioarquitectura de placenta humana, de gestación a término, partos normales, únicos, perteneciente al Servicio de Ginecología y Obstetricia, Unidad de Partos, del Hospital Hernán Enríquez Aravena, de Temuco, IX Región, Chile. Estas fueron inyectadas a través de los vasos placentarios con resina acrílica autopolimerizable, realizando luego, una corrosión por 11 días con HCL al 32,4 %, siendo hidrolizado completamente el parénquima y el estroma de la placenta, obteniéndose el molde de los vasos. Nuestros resultados confirmaron que esta técnica es útil en docencia e investigación, dado los bajos costos y excelente visualización macroscópica de la trama vascular de la placenta humana The fixation, conservation and preservation techniques, with academic and didactic aims, look for the way to find substances that maintain, as far as it is possible, the natural state of the body or organs, permeating the tissues, allowing an easy assembly, providing a detailed information and offering a three-dimensional view of the structures.The objective of the research was the view of angioarchitecture of the human placenta.

Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2010, DOI: 10.4236/ce.2010.12017
Abstract: This article describes the design and general outcome of applying a computer system that includes interactive activities to the topics of ratio and proportion. The work was undertaken with Mexican students attending primary school grade six (11 year olds). In designing the activities, our work was based on the studies of researchers who have focused on such topics, as well as on the work of researchers in the field of computer sciences and education technology. Support of the activities designed is found in psycho-pedagogy, in knowledge of mathematics and in the fields of computer sciences and education technology.
Representation Registers in the Solution of Calculus Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23036
Abstract: This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico). The article reports on the problems found among Engineering students with respect to their resistance to using different representation registers when solving optimization problems in the Calculus Learning Unit. Use of such registers could help the students to build mathematics know ledge and to solve calculus problems. As a didactic strategy, simulations are used in an electronic environment in order to support the students by fostering their use of tabular, graphical and algebraic representation registers. Interviews are undertaken of six of the professors who give the calculus courses, and a diagnostic questionnaire is applied to 68 students prior to and after working with the proposal. As for the theoretical framework, the work reported by Duval and Hitt is salient in this report, particularly their emphasis of the fact that working on activities by way of one single representation system is not sufficient. From the first responses provided by the students, one can conclude that the algebraic register is preferred by the majority of students. It is however used in a mechanical fashion without affording any meaning to the content of the problem and to the process of solving it. Another conclusion reported is that implementing tasks in the classroom in which the mathematics activity requires coherent use of different representations is necessary.
Primary and Secondary Teachers’ Knowledge, Interpretation, and Approaches to Students Errors about Ratio and Proportion Topics  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23035
Abstract: This study investigated elementary and secondary teachers’ understanding and pedagogical strategies applied to students making errors in finding a missing length in similar rectangles. It was revealed that secondary teachers had better understanding of ratio and proportion in similar rectangles than elementary teachers. While all secondary teachers solved the similar rectangles problems correctly, a large portion of elementary teacher struggled with the problem. In explaining their solution strategies, and even though similar strategies appeared both from elementary teachers and secondary teachers, a majority of secondary teachers pointed out the underlying idea of similarity, whereas less than half of the elementary teachers explained their reasoning for using ratios and proportion. This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico)
A Cognitive Analysis When the Students Solve Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34063
Abstract: The research reported in this paper shows an analysis of the cognitive process of students from the senior technical program on food technology, whom are asked to solve a contextualized event on systems of linear algebraic equations within the context of balance of matter in situations of chemical mixtures. The cognitive analysis is founded on the theories of Conceptual Fields and vents. For the analysis attention is focused on the representations carried out by students regarding the invariants in the schemes that they build when they face an event of contextualized mathematics. During the acting process of students emerge different types of representation which are appropriate to the context in which the research develops, with which a proposal for the classification of them.
Corticosteróide Antenatal: Ciclo único versus Múltiplo - Compara??o de Resultados
Meneguel, Joice Fabiola;Guinsburg, Ruth;Miyoshi, Milton Harumi;Peres, Clovis de Araújo;Kopelman, Benjamin Israel;Camano, Luiz;
Revista Brasileira de Ginecologia e Obstetrícia , 2002, DOI: 10.1590/S0100-72032002000800002
Abstract: purpose: to evaluate if multiple courses of antenatal corticosteroids are more effective than single ones to reduce morbidity and mortality of preterm infants. methods: retrospective study of 184 newborns with gestational age less than 34 weeks from a tertiary-level hospital in s?o paulo from january 1988 to december 1998. the patients were divided into two groups: single course (n=135) - newborns whose mothers were exposed to a complete single course (2 doses of betamethasone or 4 doses of dexamethasone between 24 h and 7 days prior to delivery); multiple courses (n=49) - newborns whose mothers were exposed to two or more complete courses. the primary clinical outcomes for the two groups were: frequency of respiratory distress syndrome (rds), intra-hospital mortality and combined neonatal morbidity (including the presence of the following: rds, peri-intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, sepsis or intra-hospital death). numerical data were compared by student's t test or mann-whitney test and categorical data by c2 or fisher exact test, with the odds ratio and its confidence interval. results: there were no differences between the groups that received single or multiple courses of antenatal corticosteroids in regard to the occurrence of rds (single course: 22% and multiple course: 18%), intra-hospital mortality (single course 18% and multiple 12%) and combined neonatal morbidity (single course 62% and multiple 63%). conclusions: multiple courses of antenatal corticosteroids did not reduce the morbidity and mortality of preterm infants. this study emphasizes the present guidelines that recommend the use of one single course of corticosteroid for fetal maturation in pregnant women at risk for preterm delivery.
Leadership and Faith in a School Tragedy: A School Principal’s Perspective  [PDF]

Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.55051
Abstract:

On April 15, 2008, six students (aged 16 years) and one teacher (aged 29 years) from a New Zealand school lost their lives in a river canyoning tragedy. The present study investigated the school principal’s perspective of how he led his school through the tragedy, and the role of faith in the school’s coping. The school principal was interviewed two years after the event. The school’s Christian foundation was the fundamental source of strength and guidance for the principal, as well as for students, staff, teachers, and families in the immediate aftermath of the tragedy and in the two years following (i.e., to the time of the present study), the Christian culture of the school guiding decision-making. Support from outside the school (e.g. critical incident support; teaching support from other schools; social support from community agencies and civic leaders) also played an important role in assisting the school through the tragedy, particularly in the immediate aftermath of the event. Further studies are required that allow the voices of children, families and school staff to be heard regarding leadership strategies that impact on them through a disaster.
