Effets biologiques du retard à la première maternité et du recours à l’aide médicale à la procréation sur la descendance finale
Authors: Leridon Henri
Published: October 2017

L’évolution de la fécondité dans les pays européens depuis les années 1960 a été marquée par une baisse notable de la descendance finale des générations (plus encore de l’indicateur conjoncturel) et une élévation rapide de l’âge à la première maternité, en général de 3 à 4 ans en une trentaine d’années. Dans le même temps, le recours aux méthodes d’aide médicale à la procréation (AMP) a fortement augmenté. On pourrait donc penser que cette dernière évolution est révélatrice de difficultés croissantes à concevoir, lesquelles pourraient – au moins en partie – résulter du retard dans le calendrier des naissances souhaité par les couples. Pour évaluer l’impact purement biologique du retard dans le calendrier des naissances, et le rattrapage éventuel par les méthodes d’AMP, nous utilisons un modèle de microsimulation, permettant de prendre en compte un grand nombre de paramètres, biologiques et comportementaux. Ces simulations montrent que l’effet biologique du report de 3 à 4 ans de la première naissance sur la descendance finale a été assez limité : entre 0,1 et 0,2 enfant. Quant au recours à l’AMP, il n’a compensé qu’une faible partie de cette diminution, au mieux 10 %.
A Quantitative Study on Simultaneous Effects of Governing Parameters in Electrospinning of Nanofibers using Modified Neural Network using Genetic Algorithm
Authors: Seyedin Shayan , Maghsoodloo Shima , Mottaghitalab Vahid
Published: October 2017

In this article, modified neural networks using genetic algorithms were employed to investigate the simultaneous effects of four of the most important parameters, namely; solution concentration (C); spinning distance (d); applied voltage (V); and volume flow rate (Q) on mean fiber diameter (MFD), as well as standard deviation of fiber diameter (StdFD) in electrospinning of polyvinyl alcohol (PVA) nanofibers. Genetic algorithm optimized neural networks (GANN) were used for modeling the electrospinning process. The results indicate better experimental conditions and more predictive ability of GANNs. Therefore, the approach of using genetic algorithms to optimize neural networks for modeling the electrospinning process has been successful. RSM could be employed when statistical analysis, quantitative study of the effects of the parameters and visualization of the response surfaces are of interest, whereas in the case of modeling the process and predicting new conditions, GANN is a more powerful tool and presents more desirable results.

Authors: Zhizhin G. V.
Published: October 2017

This article examines the systematized and defined laws of anomalies in the filling of the electronic orbitals of the periodic table of chemical elements. The particulars of the chemical compounds caused by these anomalies investigated. It is shown that the deviation from the accepted order of filling electron orbitals contribute to an increase in the activity of the elements. As a result, among the anomalous elements are so important for us elements such as copper, silver, gold, platinum, uranium, and others. The anomalous elements participating in the creation of complex chemical compounds lead to molecules of higher dimension.

Published: October 2017

This article focuses on the current trends of education and social change in Balochistan. This article aims to point out the issues related to globalization and geopolitical changes around the region. Balochistan is the most backward area in terms of social development in Pakistan, as it has tribal societies. The political turmoil and war in Afghanistan has been present since 1979, and has brought refugees and donor agencies into the province. This article highlights the important of understanding the impact of social change in Balochistan. The modes of employment and economic activities have witnessed major changes. Education has played a crucial role in bringing about social change in Balochistan, as it is evident in many ways in the context of employment patterns. A large number of people are now in jobs which required a certain level of education, when compared to three decades ago. It is vital to understand the very dynamics of social change at this crucial juncture, when rapid social changes are taking place.
Emotional Management in Spanish Institutions
Authors: Belli Simone
Published: October 2017

This paper seeks to explain how and why people join social movements. In a study of the Occupy movement, the authors set out to demonstrate that participation is a function of emotional attachments between participants – attachment through shared emotions regarding the loss of trust in traditional institutions and belief in efficacy of alternative, open, institutions. Using the concept of second-order emotions, the authors argue that the movement through horizontal democracy helps to regulate emotions through recognition of those emotions. The researchers argue that, in addition to a distrust of traditional institutions, social rituals in the Occupy movement serve to fortify collective emotions and create strong bonds between participants.
The Design of Disciplinarily-Integrated Games as Multirepresentational Systems
Authors: Virk Satyugjit S. , Clark Douglas B , Sengupta Pratim
Published: October 2017

Disciplinarily-integrated games represent a generalizable genre and template for designing games to support science learning with a focus on bridging across formal and phenomenological representations of core science relationships (Clark, Sengupta, Brady, Martinez-Garza, and Killingsworth, 2015; Clark, Sengupta, & Virk, 2016; Sengupta & Clark, 2016). By definition, disciplinarily-integrated games (DIGs) are therefore multirepresentational systems with the affordances and challenges associated with that medium. The current paper analyzes the DIG structure through the focal parameters framed by the DeFT framework (Ainsworth, 2006) to synthesize effective design considerations for DIGs in terms of the specific design and intended functions of the representations themselves as well as the overarching environment and activity structures. The authors leverage the literatures on embodied cognition, adaptive scaffolding, representations in science education, and learning from dynamic visualizations to address the challenges, tradeoffs, and questions highlighted by the framework. They apply these research-derived design considerations to an existing DIG (SURGE Symbolic) and to hypothetical examples of other DIGs in other domains to explore generalizability of the design considerations and the genre.
QSPR Prediction of Retention Times of Methylxanthines and Cotinine by Bioplastic Evolution
Authors: Torrens Francisco , Castellano Gloria
Published: October 2017

High-performance liquid-chromatographic retention times of methylxanthines and cotinine in human plasma and urine are modelled by structure–property relationships. Bioplastic evolution is an evolutionary perspective conjugating the effect of acquired characters, and relations that emerge among the principles of evolutionary indeterminacy, morphological determination and natural selection. It is applied to design co-ordination index, which is used to characterize retentions of methylxanthines, etc. Parameters used to calculate co-ordination index are formation enthalpy, molecular weight and surface area. Morphological and co-ordination indices provide strong correlations. Effect of different types of features like thermodynamic, fractal, etc., are analyzed. The molar formation enthalpy, fractal dimensions, etc. distinguished methylxanthines and cotinine in linear fits. Different behaviour depends on number of C+N+O atoms.

Authors: Hamadache Mabrouk , Amrane Abdeltif , Hanini Salah , Benkortbi Othmane
Published: October 2017

Quantitative Structure Activity Relationship (QSAR) models are expected to play an important role in the risk assessment of chemicals on humans and the environment. In this study, a QSAR model based on 10 molecular descriptors to predict acute oral toxicity of 91 fungicides to rats was developed and validated. Good results (PRESS/SSY = 0.085 and VIF < 5) were obtained, showing the validation of descriptors in the obtained model. The best results were obtained with a 10/11/1 Artificial Neural Network model trained with the Levenberg-Marquardt algorithm. The prediction accuracy for the external validation set was estimated by the Q2ext which was equal to 0.960. Accordingly, the model developed in this study provided excellent predictions and can be used to predict the acute oral toxicity of fungicides, particularly for those that have not been tested as well as new fungicides.

Published: October 2017

This study explored the factors that affect personal health information (PHI) disclosure via a mobile application (app) in Thailand. Since mobile apps are increasingly popular, as is the Thai people's concern on their health condition, many mobile app service providers want to know which factors would persuade customers to reveal their PHI via mobile apps. This research model was, therefore, developed and included the six factors of: personalized service, self-presentation, mobile app reputation, familiarity, perceived benefits and privacy concerns. The hypotheses were tested by structural equation modeling using the questionnaire responses from 294 valid subjects. Surprisingly, privacy concern was not significantly negatively related to the intention to disclose PHI. However, the significance effect of the perceived benefit, personalized service and self-presentation were consistent with previous studies. In addition, the respondents were willing to reveal different personal information in different situations. The implication of the result will shed light on the development of a healthcare mobile app service provider.

Published: October 2017

This exploratory article aims to evaluate the effectiveness of case study competitions in promoting the brand equity of sponsors and organizers. The article compares the managerial objectives with the responses of participating students who are the targeted audience of the marketing communications of the sponsors and examines the alignment between managerial objectives and the perceptions of participants. The quantitative data using surveys is collected from sponsors and organizers, and participants in the competition. The data is analysed using frequency tables, descriptive statistics, F-tests for equality of variances and T-tests for equality of means. The findings suggest that managers attach high importance to brand awareness (cognitive aspect), brand images and attitude (affective aspect) and less importance to brand loyalty (behavioural aspect) to enhance brand equity through sponsoring academic competitions. However, participants' responses indicate that the brand awareness aspect is not effectively realized as compared to other brand equity dimensions.

There is noticeable gap in between the actual no. of enrollments and intake capacity of these institutes. In the year 2015-2016, as per AICTE, New Delhi, 46% of seats were vacant in Technical Education in India. Segmentation and the ‘People' factor of service mixing is very important aspects in education services. The purpose of this article is to highlight the influence of the people mix on geographical and demographical factors of students in selecting technical educational institutes. Different communication strategies of people mix can be used based on geographical and demographical factors, which will confirm growth as well as the development of technical education in the proper direction.
The Application of Preoperative Computed Tomography Angiogram for Hemispherectomy
Authors: Qiu Jiqing , Cui Yu , Qi Bin , Sun Lichao , Zhu Zhanpeng
Published: October 2017

Hemispherectomy is an established neurosurgical procedure for unilateral refractory epilepsy . Even though the surgical approach has evolved greatly, prevention of catastrophic intraoperative bleeding is a challenge. It is important that surgeons know the abnormal blood vessel before surgery. Herein, we report our experience with two patients in whom computed tomographic angiography (CTA) was used in the preoperative evaluation for hemispherectomy. CTA allowed for precise anatomical delineation of the hemispheric vascular abnormalities. Preoperative CTA showed that the specific cerebral arteries and their branches ipsilateral to the lesion were slender. Elaborate preoperative planning for the surgical approach helped prevent catastrophic intraoperative bleeding. Favorable outcomes were achieved in both children. CTA appears to confer a considerable advantage in the preoperative vascular and anatomical delineation in patients scheduled for hemispherectomy. To our knowledge, this is the first report about the application of CTA for hemispherectomy preoperative planning.

Authors: Mpofu Jabulani , Sefotho Maximus M. , Maree Jacobus G.
Published: October 2017

Background: The purpose of this study was to explore the psychological well-being of adolescents with physical disabilities living in inclusive community settings of Makonde Urban in Zimbabwe. An inclusive community is one that aims to remove exclusionary practices within the community and promote community systems that accept all people irrespective of their difference. Inclusive communities on their own are not uniquely designed for people with disabilities, but most developing countries have adopted them as a basic strategy to influence and enhance psychological well-being of people with disabilities.Methods: A constructivist lived experience perspective underpinned this research, in which multiple case studies were used to interact with the participants on inclusion and psychological well-being of adolescents with physical disabilities. Purposive sampling was used to select 14 participants (9 males and 5 females). Data were collected through face-to-face interviews and transcribed verbatim. Four themes emerged from the thematic analysis of data sources.Results: It was found that participants who were adolescents with physical disabilities living in inclusive community settings of Makonde Urban in Zimbabwe were having high levels of autonomy and choice, purpose in life, positive relations with others and good personal growth and self-acceptance.Conclusion: The findings of this study should enable inclusive communities’ policy-makers and researchers to better understand the psychological well-being of adolescents with physical disabilities living in inclusive communities.

Published: October 2017

Introduction

It has been shown that in experienced hands repeated CABG is doable procedure. However the quality of life after third time CABG has not been evaluated so far.

Patients and Methods

The peri-operative data of 25 (22 male, mean age of 65.5 ± 8.0 years) consecutive patients in a single centre undergoing third time-CABG from 4/96 to 11/06 were studied. Quality of life (QoL) was assessed by Short Form (SF)-36 Questionnaire.

Results

30 day mortality was 12% (3/25). Seven died during follow-up. In 15 survivors median follow-up was 94 months (2–122 months). 1-, 5-, and 10-year survival were 77.8%, 65.0%, and 53.1%, respectively. Present NYHA status was significantly improved in comparison to preoperative values (2.4 ± 0.8 vs. 3.2 ± 0.56, p = 0.012). QoL was comparable with an age matched general population with heart insufficiency.

Conclusion

Third time CABG can be performed with acceptable peri-operative mortality. Significant improvement of NYHA status and acceptable quality of life results justifies our surgical approach in this challenging patient cohort.
Bag-of-words-based anomaly-detection principal component analysis and stochastic optimization for debris flow detection and evacuation planning

Published: October 2017

Abstract. Debris flows are natural disasters, with soil mass, rocks, and water traveling down a mountainside slope. Debris flows are extremely dangerous; their occurrence incurs huge losses to life and property. The purpose of this research is to develop debris flow detection and emergency evacuation systems. A bag-of-words model is established for analyzing the features of debris flow events, and an anomaly-detection principal component analysis (PCA) model is proposed to detect debris flow. Using real-time debris flow prediction and monitoring, a stochastic optimization model for evacuation planning is formulated. Case studies of debris flow detection in Shenmu village and Fengchiu, central Taiwan, are conducted. Shenmu village and Fengchiu are areas of high potential debris flow, and each has a population of around 800 people. The results show that combining bag-of-words and anomaly-detection PCA methods could predict 6 out of 8 occurrences of actual events, providing a prediction rate of 75 %. In addition, the models make 13 predictions, and 6 of them are correct, providing a prediction accuracy of 46 %. Optimal parameters (including window size, bag length, filter ratio of training data, and anomaly threshold) of the models are also examined to increase the accuracy of debris flow prediction.
Vocabulary Development in Science: Studying a Middle School Sheltered Classroom
Authors: Zhang Ying
Published: October 2017

This article reports how science literacy development, particularly vocabulary development occurred in a sixth-grade sheltered science classroom as a part of an eight-month ethnographic study. Specifically, the research asks how language development occurs in the science classroom from the perspective of social semiotics. The study takes a multimodal social semiotic perspective to examine how English Learners (ELs) make meaning of science vocabulary. Qualitative methods are used and the data include video and audio recordings of science lessons, field notes, formal and informal interviews with teacher and students, and classroom artifacts. Findings demonstrate that although science vocabulary was embedded in the multimodal science curriculum, actual language development was limited. The study expands the current knowledge base for developing literacy skills in science and challenges researchers and educators to reexamine the current practice on how to incorporate effective literacy education in the content area of science.
Heterocope borealis in Norway - A copepod on the move, or on the edge of its natural distribution?
Authors: Koksvik Jan Ivar , Jensen Thomas Correll , Kjærstad Gaute
Published: October 2017

The calanoid copepod Heterocope borealis has been assumed to have an extremely northern distribution in Norway, limited to the north-eastern parts of Finnmark county. The recent records of the species in Lake Fustvatn and Lake Røssvatn in Nordland county was therefore quite unexpected. These lakes are located roughly 700 km south-west of the known distribution area in Norway. There is data on planktonic and/or littoral microcrustaceans from several hundred lakes between the known localities in Finnmark and the two new records in Nordland. The distribution of H. borealis in Finland and Sweden shows a scattered occurrence both in the northern and southern parts of the countries. Possible explanations for the occurrence of the species in the two lakes in Nordland are discussed.
A MODIFICAÇÃO DA PAISAGEM NO CONTEXTO HISTÓRICO DE OCUPAÇÃO DO TERRITÓRIO DO ASSENTAMENTO SÃO MANOEL – ANASTÁCIO-MS
Authors: Ferreira Ercília Mendes , Dresch Cássia Julita , Ayach Lucy Ribeiro
Published: October 2017

O presente trabalho busca fazer uma análise espaço-temporal da evolução da paisagem a partir das contribuições obtidas na disciplina “Ecologia da Paisagem no Cerrado e Pantanal: Potencialidades e Fragilidades”, ofertada no Programa de Mestrado em Geografia da Universidade Federal de Mato Grosso do Sul e tem como objetivo geral avaliar a modificação da paisagem no contexto histórico em decorrência do uso e ocupação do território pelos moradores no período de 1988 a 2015, do Assentamento Rural São Manoel, localizado no município de Anastácio-MS, Micro Região Geográfica de Aquidauana, com uma extensão de aproximadamente 2.303,47 km². O assentamento possui uma vegetação predominantemente do Cerrado, tornando-se assim importante o monitoramento dos processos de alteração neste importante bioma. Trata-se de um estudo com foco na análise ambiental, em que se busca conhecer e compreender de forma sistemática o processo de degradação ambiental ocorrido no referido assentamento. No referencial teórico, caracteriza-se historicamente as atividades socioeconômicas e ambientais do local, assim como um recorte temporal de imagens subsidiadas com as técnicas e ferramentas do geoprocessamento: Processamento Digital de Imagens de satélite do sensor LANDSAT-5 (bandas 3, 4 e 5, ano 1988) e imagem LANDSAT-8 (bandas 4, 5 e 6, ano 2015) e o trabalho de reconhecimento de campo. Foram consideradas as medidas de classes: mata, pastagem e solo exposto. Os resultados obtidos através do cruzamento e da análise de informações espacializadas indicaram que a paisagem, de 1988 a 2015, passou por momentos distintos: sua vegetação característica do Cerrado já sofria pressão antrópica antes da criação do assentamento; com a distribuição dos lotes e no decorrer do tempo em que várias tentativas sem sucesso foram realizadas com a finalidade de melhorar a qualidade de vida dos moradores, a repetição e a intensidade da ação por parte do homem em relação ao meio ambiental geraram consequências como o aumento de solos expostos. Ações como extração de madeiras para a confecção de dormentes para as linhas férreas explorada pelo antigo proprietário da área, assim como a substituição da vegetação nativa por espécie de gramíneas exóticas realizada pelos assentados em seus lotes, vêm modificando e fragilizando o bioma Cerrado, gerando indiretamente consequências que futuramente poderão afetar seriamente os recursos hídricos da referida área de estudo.

Published: October 2017

A comunidade tradicional pesqueira da Praia das Fontes está localizada no município de Beberibe, litoral leste do Ceará, possui um modo de vida que associa valorização e conhecimento dos aspectos ambientais às práticas econômicas locais, como a pesca tradicional, artesanato, pequenos comércios e atividades ligadas ao turismo. No território ocupado por essa população verificam-se ambientes naturais atualmente valorizados pela sociedade, como riachos, fontes de água doce, campo de dunas, praia e falésias de areias coloridas que atraem elevado fluxo turístico acompanhado da expansão imobiliária, causando problemáticas socioambientais. Deste modo, pretende-se discutir a utilização das técnicas e produtos cartográficos como ferramentas de uso social para a garantia do território diante das pressões vivenciadas. Nesse sentido, realizaram-se encontros com os moradores da Praia das Fontes visando promover o mapeamento social do território e das áreas de pesca. A partir das reuniões foi possível refletir as demandas e os desafios da comunidade, e, assim, fortalecer o processo de articulação comunitária e construir um produto cartográfico voltado para a reinvindicação de direitos sociais junto aos órgãos públicos. Destaca-se que tal iniciativa aproximou sociedade e academia, cumprindo o papel social da universidade e contribuindo para o fomento da conservação da natureza e da cultura tradicional comunitária.

Published: October 2017

A finalidade deste artigo é refletir sobre as injustiças ambientais na cidade média de Sobral/CE. O objetivo principal foi propor um mapeamento das injustiças ambientais no município, a partir da análise de duas problemáticas: distribuição da renda na cidade e os riscos ambientais (áreas de alagamento e linhas de transmissão). Primeiramente, realizamos uma discussão sobre os fatores que favoreceram a concentração populacional na cidade, a desconcentração industrial em 1970, a emergência das cidades médias na década de 1990, bem como, sua importância econômica e social. Em seguida, elaboramos uma breve introdução sobre as finalidades da justiça ambiental, em especial, no Brasil, depois fizemos um paralelo entre o desenvolvimento urbano e suas contradições socioambientais na cidade. Entrando no contexto de Sobral, apontamos os principais problemas relacionados ao acesso da população pobre aos bens e serviços públicos e a sua fixação em áreas de risco de alagamento e próximas as linhas de transmissão. Realizamos um registro fotográfico e a localização das áreas de riscos. E por último, discutimos e constatamos as contradições socioambientais encontradas no espaço urbano de Sobral, ou seja, a população de baixa renda, na sua maioria, localiza-se em áreas de riscos, estando mais vulnerável aos riscos ambientais da cidade.

Published: October 2017

O presente trabalho objetivou a análise a partir da utilização dos perfis geoambientais tendo como base a relação dos aspectos físicos e a interferência do uso e ocupação do solo e as consequentes vulnerabilidades socioambientais para a bacia do Córrego Biquinha, localizado em Barbosa Ferraz, região centro ocidental do Estado do Paraná. O método seguiu a proposta de representação horizontal e vertical do ambiente dos perfis geoambientais, configuradas na abordagem sistêmica de Monteiro (2001). Adaptou-se o método empregado por Graça e Silveira (2009) e Sesco, Graça e Silveira (2010) para identificar a vulnerabilidade socioambiental. A partir do levantamento das características mencionadas anteriormente, a integração e síntese destas informações e das observações em campo, estabeleceu-se um diagnóstico socioambiental que permite subsidiar o estabelecimento do planejamento ambiental da área de estudo. A escolha de três diferentes transectos de acordo com a pluralidade dos componentes do ambiente possibilitou um diagnóstico da bacia em três faixas amostrais ao longo do curso (alto, médio e baixo) e mostrou a vulnerabilidade socioambiental frente à variação do regime pluviométrico, com a intensificação do potencial de processos erosivos, da probabilidade de alagamentos, a retirada de rochas e deposição de sedimentos. A área de estudo apresenta relevantes empecilhos para o uso e ocupação do solo urbano e rural e restrições que são altamente agravadas com a intensificação das chuvas durante o verão e a primavera.
A PRESENÇA DOS MIGRANTES HAITIANOS EM TERRITÓRIO MARINGAENSE
Authors: Gomes Sueli De Castro
Published: October 2017

O acordo entre Brasil e Haiti, concedendo vistos humanitários, trouxe para o Brasil uma nova corrente migratória. Assim, em 2010, chegaram os primeiros haitianos no município de Maringá e arredores, no Paraná. Esse fluxo abriu caminhos para outros grupos migratórios como os dominicanos, os senegaleses e os bengaleses. Em 2014, já eram 4 mil haitianos residindo na Região Metropolitana de Maringá. No ano de 2016, com a mudança econômica local e nacional, parte expressiva dos haitianos de Maringá migraram principalmente para o Chile. Esses homens foram mobilizados para trabalhar, sobretudo, nos frigoríficos da região, e em menor participação, em outras indústrias de grande porte, além do setor de comércio e serviços. Nosso propósito, neste texto, é discutir a presença dos migrantes haitianos na região metropolitana de Maringá, suas formas de inserção, e os obstáculos por eles encontrados, identificando as barreiras para sua integração na sociedade. Nesse quadro de mobilidade humana, apoiamo-nos em Jean Paul Gaudemar (1977), que estudou a produção e a circulação da força de trabalho; com o respaldo de Marx e Foucault, esse autor traça um paralelo do poder nas microesferas e o domínio do capital sobre os homens.
Injury-related falls from bicycles, skateboards, roller skates, and non-motorized scooters in the United States: 2005 - 2014
Authors: Milczarski William , Tuckel Peter , Maisel Richard
Published: October 2017

Purpose: To provide an updated and comparative analysis of injury-related falls from bicycles, skateboards, roller skates and non-motorized scooters.Methods: The study uses two national databases – the Nationwide Emergency Department Sample and the Nationwide Inpatient Sample  – and subnational databases for New York, California, and Maryland.  Univariate and multivariate analyses (negative binomial regression) are performed to identify effects of age, gender, racial-ethnic background, and region on the incidence of injury-related falls from each of the four devices.Results: The rate of injuries due to falls from bicycles far surpasses the rates due to falls from the other devices.  When a measure of “exposure” is taken into consideration, however, the rate of injuries from skateboards outstrips the rates from bicycles or roller skates.  The profile of patients who are injured from falls from each of the four devices is distinctive.  Asian-Americans are greatly underrepresented among those who suffer a fall-related injury from any of the four devices.  The incidence of injuries attributable to falls varies considerably by geographic region.Conclusions: Public health officials need to be mindful that while certain activities such as scootering might be gaining in popularity, the number of injuries sustained from bicycles still dwarfs the number attributable to falls from skateboards, roller skates, and scooters combined.  Thus special attention needs to be paid to both prevent falls from bicycles and specific treatment modalities.  It is important for public health officials to gather injury data at the local level to allocate prevention and treatment resources more efficiently.

Background/Objective: Febrile convulsions (FCs) are the most common convulsive disorder of childhood, and represent a benign condition in children. FC occurrence can affect negatively on the familial quality of life and the parents may experience anxiety and fear with every time child develops fever. Therefore, parents and care givers should be educated about febrile convulsion and its home management.  The aim of this study was to evaluate the effect of implementing an educational module on mother's knowledge, home management and attitude about febrile convulsion.Methods: A quasi experimental research design using one group pre & post-test was used. The study sample included 107 mothers of children with febrile convulsion according to statistical consultant and statistical formula. The inclusion criteria were: all mothers of children with first or recurrent FC and the children age was from 6 months to five years. The study was conducted at the Emergency department, outpatient clinic and medical word affiliated to Mansoura University Children's Hospital, Egypt.   Results: It was found that, fifty two percent (52.3%) of studied children were boys with the mean age were Mean ± SD 2.76 ± 1.30 for children and 30.29 ± 6.41 for mothers. Percentage of studied mother with good knowledge at base line was low (11.2%) while, this percentage was improved to 65.4% with a mean knowledge score 3.98 ± 2.18 before module and 9.70 ± 1.56 after module implementation. In addition, sixty four percent (64.4%) of studied mothers had inappropriate practice and home management compared to less than half (44.9%) after module implementation; the difference was statistically significant (p = .005). Only 25.3%  of mothers had positive attitude about febrile convulsion before module implementation and this percentage was improved to 57.9% after module implementation with the mean score of attitude 18.42 ± 5.84 before module and 24.71 ± 6.76 post module implementation and the difference was statistically significant (p = .025).Conclusions: The study concluded that, the use of educational intervention programs and mothers support group were influenced positively in improving mothers’ knowledge, home management & attitude about FC and its management; but still some mothers having inappropriate home management and negative attitude. Therefore, it is recommended further education in the pediatric clinic or via mass media.

This research was aimed at developing printed teaching materials of Atomic Physics PEFI4421 Course usingResearch and Development (R & D) model; which consisted of three major set of activities. The first set consisted ofseven stages, the second set consisted of one stage, and the third set consisted of seven stages. This research studywas scheduled at the first year of the course development. This study concluded that (1) the teaching materials usedfor Atomic Physics Course PEFI4421 were necessary to be revised and updated since many of the materials wereoutdated, (2) the materials and concepts of Atomic Physics were hard to be learned by the students independentlywithout face-to-face tutorials, (3) the exercises used in the handout were not clearly described in detail making themto be difficult to be completed, and (4) the physical presentation of the course materials needed improvementbecause they are lack of attractiveness for the students to use.
Relación entre el pensamiento crítico y el desempeño académico en alumnos de escuela preparatoria
Authors: Lucio García Bianca , Vázquez Botello Armando

A nivel internacional, la importancia de desarrollar el pensamiento crítico (PC) entre los alumnos desde la escuela debiera ser una tarea primordial para cada sistema educativo, y relacionarlo con el ejercicio académico, otra. La investigación que presentamos determinó el nivel de pensamiento crítico en estudiantes de escuela preparatoria, así como si aquel mantiene alguna relación con el desempeño escolar de los educandos. Además, se describen las características más sobresalientes de la muestra estudiada. Con estas consideraciones, se responde a dos preguntas primordiales: ¿cuál es el nivel de PC en estudiantes de preparatoria con edades que oscilan entre los 15 y los 18 años? y ¿existe alguna relación entre el desempeño académico de los alumnos con el nivel de PC que presentan? La investigación tiene un enfoque de tipo cuantitativo, y el diseño es no experimental de tipo transeccional, descriptivo y correlacional. Se determinó el PC con la prueba de pensamiento crítico de Cornell, y los resultados obtenidos se procesaron a través del paquete de software para datos estadísticos STATA Versión 11.
Percepciones sobre la educación de personas adultas. Análisis de la formación, la práctica docente y el perfil profesional
Authors: Rodríguez Correa Marisol , Rivadulla-López Juan-Carlos
Published: October 2017

En los últimos años, la educación y la formación de adultos ha adquirido tal desarrollo que cada vez son más las personas cuya actividad profesional gira en torno a este ámbito. Sin embargo, en una sociedad incierta y altamente competitiva en la que se demandan más actividades formativas, el profesorado de dicha disciplina sigue sin recibir la formación específica necesaria para enfrentarse a esa realidad. Este vacío formativo ha sido una de las principales razones que nos han impulsado a querer conocer, desde la voz de sus protagonistas, las percepciones que tienen los profesores de educación de personas adultas (EPA) sobre su labor pedagógica, para así tratar de identificar un perfil docente de los mismos. En esta investigación, participaron 90 enseñantes de EPA de Galicia (España), y la recogida de datos se realizó mediante un cuestionario tipo Likert. Los resultados muestran que los docentes consideran que la EPA es poco valorada por la sociedad, que requieren mayor formación específica y que no creen que su labor sea una profesión.
Development of an LC-MS/MS Determination Method for T-2 Toxin and Its Glucoside and Acetyl Derivatives for Estimating the Contamination of Total T-2 Toxins in Staple Flours
Authors: Nakagawa Hiroyuki , Matsuo Yosuke , McCormick Susan , Lim Chee Wei
Published: October 2017

A determination method previously validated for trichothecenes and zearalenone by means of liquid chromatography-tandem mass spectrometry (LC-MS/MS) was adapted for the quantification of T-2 toxin (T-2) as well as its glucoside and acetyl derivatives, T-2-3-glucoside (T-2-3G) and 3-acetyl-T-2 (3A-T-2). HT-2 toxin (HT-2) and its acetyl derivative 3-acetyl-HT-2 (3A-HT-2) were also included as the target chemicals. Staple flours (56 samples collected from the Singapore market) were examined for contamination from T-2 and/or HT-2 and their derivatives. Among them, 16 flours were found to be contaminated with T-2 and/or HT-2, whereas none was contaminated with T-2-3G and 3A-HT-2, except for trace 3A-T-2 detected in 2 rye samples. Rye flour samples were frequently contaminated with both T-2 and HT-2. Some of the reference materials (RMs) were further analyzed, and T-2-3G and 3A-T-2 were quantitatively detected in corn and wheat RMs. The ratio of T-2-3G to T-2 in the RMs seemed to be much lower than the ratio of deoxynivalenol-3-glucoside to deoxynivalenol usually reported in former studies. To the best of our knowledge, the natural contamination of 3A-T-2 in staple flour is reported here for the first time.
Fetal Vascular Malperfusion
Authors: Heider Amer
Published: October 2017

Context.—

Fetal vascular malperfusion, also known as fetal thrombotic vasculopathy, remains an underrecognized pathologic finding and should be noted during placental evaluation.

Objective.—

To review histologic findings, gain familiarity with the updated terminology, and to recognize important clinical associations with this entity.

Data Sources.—

University of Michigan cases, PubMed search, multiple review articles including recent placental workshop group consensus statement, and selected book chapters.

Conclusions.—

Multiple histologic patterns of fetal vascular malperfusion have been described including thrombosis, avascular villi, villous stromal-vascular karyorrhexis, intramural fibrin thrombi, and stem villous vascular obliteration. Various underlying etiologies can be involved in fetal vascular malperfusion. Cord lesions including abnormal insertion, length, and coiling are important causes. Maternal vascular malperfusion such as preeclampsia, hypercoagulable states, lupus anticoagulant, and sometimes diabetes have been associated with this condition. Fetal cardiac dysfunction/malformations and severe fetal inflammatory response in the setting of ascending intrauterine infection have also been attributed to this important finding. Fetal vascular malperfusion has been implicated in several significant and sometimes devastating clinical associations; these include intrauterine growth restriction, poor perinatal outcome, fetal demise, and neurodevelopmental sequelae. A diagnostic challenge may be encountered in cases with prior intrauterine fetal death, since degenerative changes post demise result in a similar histomorphologic picture. The diffuse versus the focal nature of the lesions may help in the distinction.
Histologic Mimics of Basal Cell Carcinoma
Authors: Stanoszek Lauren M. , Wang Grace Y. , Harms Paul W.
Published: October 2017

Context.—

Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma. Thus, misdiagnosis has significant potential to result in overtreatment or undertreatment.

Objective.—

To review key features distinguishing BCC from histologic mimics, including current evidence regarding immunohistochemical markers useful for that distinction.

Data Sources.—

Review of pertinent literature on BCC immunohistochemistry and differential diagnosis.

Conclusions.—

In most cases, BCC can be reliably diagnosed by histopathologic features. Immunohistochemistry may provide useful ancillary data in certain cases. Awareness of potential mimics is critical to avoid misdiagnosis and resulting inappropriate management.
