RESUMO O descarte de resíduos de lodo de curtume no solo tem sido um problema ambiental devido aos altos teores de cromo. O objetivo deste trabalho foi avaliar a dinâmica dos óxidos de ferro e os teores de cromo ligados a esses minerais em áreas de descarte de resíduos de curtume. Para isso, foram determinados os teores de ferro e cromo extraídos por oxalato de amônio dos óxidos de baixa cristalinidade e por ditionito-citrato-bicarbonato (DCB) dos óxidos cristalinos na fração argila do solo. Esses teores variaram entre 3,5 e 4,1 mg kg-1 nos tratamentos sem aplicação de lodo de curtume e entre 19,9 e 56,8 mg kg-1 nos com adição de lodo. Os teores de cromo extraídos dos óxidos cristalinos variaram entre 21,3 e 23,3 mg kg-1 nos tratamentos sem aplicação de lodo e entre 46,4 e 103,0 mg kg-1 nos com uso de lodo de curtume. A aplicação desse material proporcionou um aumento na relação do ferro extraído do óxido de ferro e o ferro extraído com o ditionito (Feo/Fed) dos óxidos da área de descarte, o que evidencia uma diminuição da cristalinidade dos óxidos. Foi encontrada uma redução na relação do ferro extraído com o ditionito e do cromo extraído com o ditionito (Fed/Crd), o que mostra a substituição do ferro pelo cromo nos óxidos, evidenciando uma troca isomórfica. Essa alteração pode ser uma alternativa para a retenção de cromo pelo solo com grande força.

Published: May 2018

RESUMO O artigo teve como objetivo apresentar uma metodologia para caracterização da qualidade de água na Bacia Hidrográfica do Açude Acarape do Meio, no semiárido brasileiro. O mapeamento do uso do solo e o monitoramento de parâmetros de qualidade de água possibilitaram a identificação de fontes poluidoras e a construção do diagnóstico da bacia. A partir da modelagem da qualidade de água, 37 km do Rio Pacoti foram classificados como classe 4, exceto sua nascente, que ficou na classe 2. As principais fontes poluidoras para a degradação dos corpos hídricos foram as deficitárias Estações de Tratamento de Esgoto (ETEs), a falta de saneamento básico na zona rural, a pecuária e a atividade agrícola. O modelo QUAL-UFMG estimou a carga de entrada de fósforo no açude em 13,7 ton.ano-1 para uma concentração de 0,56 mg.L-1 e vazão média em 1,48 m³.s-1. Os coeficientes calibrados K1, Ks, Kd, Kb, Kspo, Koi e K2 foram iguais a 0,45 d-1, 0,29 d-1, 0,68 d-1, 0,65 d-1, 0,1 d-1, 0,01 d-1 e 5,4 d-1, respectivamente. Avaliaram-se as intervenções políticas e infraestruturais na bacia em dois cenários: melhoria na eficiência de operação das ETEs e efetivação de políticas públicas, que reduziram consideravelmente a carga de fósforo.
Higienização de lodo de esgoto em reator com aquecimento solar: inativação de coliformes totais e Escherichia coli
Authors: Fogolari Odinei , Magri Maria Elisa , Philippi Luiz Sérgio
Published: May 2018

RESUMO O uso de lodo de esgoto na agricultura se tornou prática corrente em diversos países, sendo atrativa em muitos aspectos, principalmente no fornecimento de matéria orgânica e nutrientes ao solo. Embora os benefícios ambientais e agrícolas do uso de lodo sejam consideráveis, tal prática deve ser realizada de forma sanitariamente segura. Nesse contexto, o objetivo deste estudo foi avaliar a eficiência de um processo de higienização térmica de lodo de esgoto utilizando energia solar. O lodo era aquecido através de um trocador de calor, construído com tubos de cobre e instalado dentro do reator, no qual circula água aquecida em coletores solares planos. Foram realizados 16 ensaios experimentais em diferentes condições de irradiação solar. A inativação térmica da Escherichia coli foi avaliada através do modelo cinético de primeira ordem em condições não isotérmicas. O processo mostrou-se eficiente em ensaios realizados com irradiação solar média do período acima de 500 W.h.m-2, com redução de E. coli entre 4,2 e 7,1 log10 e de coliformes totais entre 4,8 e 7,4 log10. Os ensaios realizados em dias com menores índices de irradiação solar tiveram a eficiência de higienização comprometida, devido às baixas temperaturas atingidas pelo lodo.

ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model.

Abstract Objective We evaluated the association between vitamin D levels and nutritional status, pulmonary function and pulmonary exacerbations in children and adolescents with cystic fibrosis. Methods 25-hydroxyvitamin D (25(OH)D) levels of 37 children and adolescents were retrospectively evaluated. Pulmonary function, body mass index, height for age, and pulmonary exacerbations episodes were associated with vitamin D levels divided into two groups: sufficient (≥30ng/mL) and hypovitaminosis (<30ng/mL). Results Hypovitaminosis D (25(OH)D <30ng/mL) was observed in 54% of subjects. The mean level of 25(OH)D was 30.53±12.14ng/mL. Pulmonary function and nutritional status were not associated with vitamin D levels. Pulmonary exacerbations over a 2-year period (p=0.007) and the period from measurement up to the end of the follow-up period (p=0.002) were significantly associated with vitamin D levels. Conclusion Hypovitaminosis D was associated with higher rates of pulmonary exacerbations in this sample of children and adolescents with cystic fibrosis. Hypovitaminosis D should be further studied as a marker of disease severity in cystic fibrosis. Further prospective and randomized studies are necessary to investigate causality of this association.

Abstract Objective To evaluate the correlation between physical examination data concerning hip rotation and tibial torsion with transverse plane kinematics in children with cerebral palsy; and to determine which time points and events of the gait cycle present higher correlation with physical examination findings. Methods A total of 195 children with cerebral palsy seen at two gait laboratories from 2008 and 2016 were included in this study. Physical examination measurements included internal hip rotation, external hip rotation, mid-point hip rotation and the transmalleolar axis angle. Six kinematic parameters were selected for each segment to assess hip rotation and shank-based foot rotation. Correlations between physical examination and kinematic measures were analyzed by Spearman correlation coefficients, and a significance level of 5% was considered. Results Comparing physical examination measurements of hip rotation and hip kinematics, we found moderate to strong correlations for all variables (p<0.001). The highest coefficients were seen between the mid-point hip rotation on physical examination and hip rotation kinematics (rho range: 0.48-0.61). Moderate correlations were also found between the transmalleolar axis angle measurement on physical examination and foot rotation kinematics (rho range 0.44-0.56; p<0.001). Conclusion These findings may have clinical implications in the assessment and management of transverse plane gait deviations in children with cerebral palsy.
CIDADANIZAÇÃO E ETNOGÊNESES NO BRASIL: APONTAMENTOS A UMA REFLEXÃO SOBRE AS EMERGÊNCIAS POLÍTICAS E SOCIAIS DOS POVOS INDÍGENAS NA SEGUNDA METADE DO SÉCULO XX
Authors: Fernandes Fernando Roque
Published: May 2018

Resumo Historicamente os povos indígenas têm se articulado na luta por seus direitos frente à comunidade. Muitos grupos, ao usarem estratégias específicas, desenvolveram processos de emergências políticas na luta pelo reconhecimento de suas diferenças. A partir da Constituição de 1988 e devido a importantes fenômenos sociais, muitos grupos passaram a ter seus direitos humanos reconhecidos juridicamente. Acreditamos que as associações e organizações indígenas e pró-indígenas que emergiram a partir da segunda metade do século XX articularam estratégias particulares que resultaram no reconhecimento das especificidades dos povos indígenas frente ao Estado brasileiro. A nosso ver, fenômenos de etnogênese e etnicidade constituem a base do protagonismo indígena na história do Brasil.
ROTULAÇÃO E SELETIVIDADE POLICIAL: ÓBICES À INSTITUCIONALIZAÇÃO DA DEMOCRACIA NO BRASIL
Authors: Soares Flávia Cristina , Ribeiro Ludmila Mendonça Lopes
Published: May 2018

Resumo: Este artigo apresenta uma revisão dos estudos produzidos no Brasil, a partir da teoria da rotulação, sobre o funcionamento do sistema da justiça criminal, com destaque para as ações policiais. O balanço da literatura indica que os indivíduos jovens, negros e pobres são os mais suscetíveis ao rótulo de criminoso pelas polícias e pelo Poder Judiciário, institucionalizando a cidadania disjuntiva. Os resultados permitiram concluir que há um descompasso entre o ideal da democracia e a realidade construída por meio das instituições que são encarregadas da produção da justiça no país, contribuindo para a reificação de desigualdades sociais, fato que bloqueia o desenvolvimento da democracia.
Relación entre la resiliencia y la satisfacción con la vida en una muestra de mujeres con cáncer de mama
Authors: Zayas Antonio , Gómez-Molinero Rocío , Guil Rocío , Gil-Olarte Paloma , Jiménez Orozco Encarna
Published: May 2018

La Sociedad Española de Oncología Médica (SEOM, 2017) señala que el cáncer de mama es la neoplasia más frecuente en mujeres españolas. En las últimas décadas ha aumentado el número de estudios desde una óptica salutogénica. Así, la resiliencia, enmarcada dentro de la psicología positiva, es la capacidad de las personas para resistir y sobreponerse a situaciones traumáticas, (Águila, 2000). De acuerdo con la literatura, existe una relación positiva entre la resiliencia y el bienestar psicológico en mujeres con cáncer de mama (Guil et al., 2016). Por lo tanto, cabe esperar que la satisfacción con la vida guarde relación con la resiliencia, al tratarse de un concepto más amplio y  con mayor estabilidad que el bienestar psicológico. Por tanto, nuestro objetivo es analizar la relación existente entre la resiliencia, en todas sus dimensiones, y la satisfacción con la vida, así como analizar la capacidad predictiva que tiene una sobre otra. La muestra estuvo conformada por 30 mujeres con cáncer de mama, con una media de edad de 47,47 años (SD=6.356) atendidas en el Hospital de Jerez en el momento de la evaluación. Se utilizó la Escala de Resiliencia de Wagnild y Young, (1993) y la Escala de Satisfacción con la Vida de Diener, Emmons, Larsen y Griffin. Los resultados muestran correlaciones positivas estadísticamente significativas entre la resiliencia, concretamente en sus dimensiones “Ecuanimidad”, “Confianza en sí mismo”, “Perseverancia” y la Satisfacción con la Vida. En los análisis de regresión, la resiliencia no ha mostrado capacidad predictiva significativa sobre la Satisfacción con la Vida. A pesar de haberse encontrado relación entre ambas variables, así como conocerse la dirección positiva de dicha relación, no se puede concluir que la resiliencia sea un predictor de la satisfacción con la vida en esta muestra.

Authors: García- Tormo J. Vicente
Published: May 2018

En la actual Sociedad de la Información existe un número creciente de herramientas tecnológicas gratuitas o de bajo coste que pueden ser empleadas para la mejora de los procesos formativos en la enseñanza superior. Éste es el caso de los formularios on-line (Google Forms), los cuales pueden ser cumplimentados haciendo uso de cualquier dispositivo móvil, tales como smartphone, tablets, ordenadores, … instrumentos que hoy en día son usados permanentemente por los alumnos/ as. Con frecuencia, los estudiantes no son totalmente conscientes de los progresos en la adquisición de conocimientos o competencias que conlleva su participación en enseñanzas oficiales. Es por ello, que el en contexto de un título oficial de enseñanza de posgrado de reciente implantación en la Universidad de León, el Máster Universitario en Entrenamiento y Rendimiento Deportivo, se ha aplicado un instrumento tecnológico (formularios on-line de recogida de información) encaminado a que los alumnos/as hagan consciente sus aprendizajes y progresos en sus competencias vinculados con las materias que cursan. Estos formularios, a su vez han permitido a los responsables de las asignaturas impartidas en estos estudios, recoger información que podrá ser rápidamente empleada en la toma de decisiones para adaptar/adecuar el proceso formativo a las necesidades y realidades de los estudiantes, así como para la optimización y mejora del mismo. Esta iniciativa ha tenido muy buena acogida tanto por los estudiantes como por el equipo docente, con una gran participación y aceptación, aportado una imagen muy positiva de innovación y actualidad de este título oficial de la Universidad de León. Este estudio se ha desarrollado dentro del Plan de apoyo a la innovación docente de la Universidad de León (PAID 2017), bajo el título “Aplicación de TICs (Formularios On-Line) como metodología docente activa en el Máster Universitario en Entrenamiento y Rendimiento Deportivo”.
La tutoría afectiva y el cambio terapeútico
Authors: Santana Navarro Cristina , Díaz - Negrín Mª Elena , Luján Henríquez Isabel
Published: May 2018

El presente trabajo recoge el diseño de un programa de intervención individualizada mediante tutorías afectivas, cuyo objetivo es generar cambios tanto en la manera de afrontar la realidad la población adolescente como de formar a tutores afectivos. La propuesta surge, por un lado, desde la reflexión realizada sobre la gran cantidad de jóvenes que manifiestan conductas desadaptadas debido a conflictos en diversos ámbitos de su vida y cuya influencia y /o consecuencias se suelen observar en los centros escolares. Por otro lado, desde la apreciación de falta de claridad y de sistematización existente en los diseños y programas relativos a las tutorías afectivas. Así, hemos encontrado un vacío sobre cuáles podrían ser las medidas reeducadoras para aplicar en cada caso, pues no se han definido instrumentos concretos que pueda emplear el tutor-afectivo, ni delimitado de forma clara y concisa la población participante, ya que estas tutorías se llevan a cabo sin designar a un/a profesional formado en habilidades y conocimientos para servir de ayuda y apoyo desde la atención a la diversidad. En consecuencia, se diseña una propuesta de intervención individualizada con la pretensión de superar esta falta de concreción y la ambigüedad en relación a qué son las tutorías afectivas, qué variables van asociadas a las mismas y cómo deber ser el proceso de tutorización. Es una propuesta fundamentada en modelos teóricos concretos (teoría de los moldes cognitivo- afectivos de Hernández-Guanir y terapias contextuales de tercera generación), en la que se delimita criterios claros para seleccionar a los sujetos participantes, se diseñan instrumentos y materiales específicos y se establecen sesiones formativas para los tutores afectivos. Los resultados aportados a través de entrevistas en profundidad, realizadas a una muestra piloto de docentes que han implementado el programa, señalan como apropiado el procedimiento establecido, pues consideran que atiende al alumnado en su dimensión personal, afectiva y social con resultados positivos en todas las áreas.
Un programa on-line como recurso de apoyo para las familias reconstituidas
Authors: Triana Pérez Beatriz
Published: May 2018

La sociedad española está compuesta actualmente por una gran diversidad de modelos de familia. Entre ellos destacan las familias reconstituidas, cada vez más comunes, como efecto del incremento de rupturas familiares que se han producido en las últimas décadas. Una de las principales características de estas familias es la dificultad para alcanzar la cohesión entre sus miembros y poder evitar así que se produzca una nueva ruptura. Ello se debe, entre otros factores, a la complejidad de su estructura, a la idiosincrasia de las nuevas relaciones que aporta (por ejemplo, entre padrastros/madrastras y los hijastros, o entre hermanastros), y también al desconocimiento que tiene la sociedad sobre dichas familias y cómo desplegar dinámicas positivas en ellas. En consecuencia, se hace necesario promover acciones de intervención que ayuden a lograr su estabilidad y permanencia. La Recomendación sobre políticas de apoyo al ejercicio positivo de la parentalidad (The Council of Europe Recommendations, Rec, 2006) enfatiza la necesidad de proveer de recursos de apoyo psicoeducativo a las familias. Éstos pueden hacerse a través de cursos presenciales, o también mediante recursos web englobados dentro del concepto de e-parenting. El objetivo de esta comunicación es presentar los rasgos principales de un módulo de un programa basado en las nuevas tecnologías de la información para la orientación e intervención familiar, dirigido a este tipo de familias. Dicho programa se basa en la metodología del aprendizaje experiencial, donde los participantes acceden al programa de forma flexible, según su propia disponibilidad temporal. El módulo consta de dos sesiones, que aglutinan múltiples actividades, en los que se tratan contenidos relacionados con situaciones cotidianas de las familias reconstituidas que son altamente representativas.
Light/dark preference test for adult zebrafish (Danio rerio) v1
Authors: Maximino Caio
Published: May 2018

The light/dark test is increasingly being adopted as one of the main behavioral assays in zebrafish neuroscience research. It is based on the innate preference of adult zebrafish for a black vs. a white compartment. Modifications and extensions of the protocol increased its breadth, but also its heterogeneity. The protocol presented here involves confining the animal in a central compartment for a initial 3-min acclimation period, followed by free exploration of an acryllic tank with a black and a white compartment. In addition to observing the spatial distribution of the animal, "ethological" variables (risk assessment, erratic swimming, freezing, thigmotaxis) are also manually scored in the white conpartment; these endpoints are selectively sensitive to drug treatments. The protocol is intended to measure anxiety-like behavior, with anxiogenic effects decreasing time on white and increasing risk assessment and thigmotaxis; some treatments also increase erratic swimming and freezing.
Phospholipid composition of the inner mitochondrial membrane of rat hepatocytes upon development of different types of steatohepatosis
Authors: Voieikova D. , Stepanova L. , Beregova T. , Ostapchenko L. , Kondro M.
Published: May 2018

Nonalcoholic fatty liver disease (NAFLD) or steatohepatosis has recently become widespread, but its pathogenesis has not been thoroughly understood for today. Most scientists have appropriated a central role in the mechanisms of its development to mitochondria and so-called "mitochondrial dysfunction," which is observed in most animal models and in most patients. The aim of this work was to determine phospholipid composition of inner mitochondrial membrane of rat hepatocytes under diet-induced and glutamate-induced steatohepatosis, as well as to compare the data about developing steatohepatosis of different types. Obtained data indicate the disruption of normal functional state of the inner mitochondrial membrane under the conditions of diet-induced and glutamate-induced steatohepatosis. Amount of oxidized forms of the major phospholipids including cardiolipin, indicates the increasing oxidative stress under the conditions of both steatohepatosis types.

Changes in structure of fibrosis of rat spinal cord induced using intervertebral disc rupture fibers method due to application longidaza and diprospan mixture. Simultanious epidural application of hyaluronidase and betamethasone in preparation of diprospan and longidasa had high synergistic effect and antifibrosis activity. Through anti-inflammatory effect and ability to reduce epidural scars adhesion this complex, to our opinion, has perspective in therapy of epidural spinal cord fibrosis.
The Cardiovascular Benefits Associated with the Use of Sodium-glucose Cotransporter 2 Inhibitors – Real-world Data
Authors: Gallwitz Baptist
Published: May 2018

Type 2 diabetes (T2D) is associated with numerous comorbidities that significantly reduce quality of life, increase mortality and complicate treatment decisions. In a recent cardiovascular outcomes trial, Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME), the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin was shown to reduce cardiovascular (CV) mortality and heart failure in high-risk patients with T2D with a previous CV event or with established CV disease (CVD). Recently published data from the Canagliflozin Cardiovascular Assessment Study (CANVAS-PROGRAM) study suggested that the cardiovascular benefits of empagliflozin are also seen with the SGLT2-inhibitor canagliflozin, indicating a class effect of SGLT2 inhibitors. Evidence for a class effect has also been shown by meta-analyses and real-world studies, including the Comparative Effectiveness of Cardiovascular Outcomes in New Users of SGLT-2 Inhibitors (CVD-REAL) and The Health Improvement Network (THIN) databases. These findings also suggest the results of EMPA-REG OUTCOME can be applied to patients with T2D with a broader CV risk profile, including people at low risk of CVD.
Mind–Body Interactions and Mindfulness Meditation in Diabetes
Authors: Priya Gagan , Kalra Sanjay
Published: May 2018

Diabetes is associated with significant psychological distress. It is, therefore, important to ensure the physical and emotional as well as psychosocial wellbeing of individuals living with diabetes. Meditation-based strategies have been evaluated for their complementary role in several chronic disorders including depression, anxiety, obesity, hypertension, cardiovascular disease and diabetes. The practice of meditation is associated with reduction in stress and negative emotions and improvements in patient attitude, health-related behaviour and coping skills. There is increased parasympathetic activity with reduction in sympathetic vascular tone, stress hormones and inflammatory markers. Additionally, several studies evaluated the role of mindfulness-based stress reduction in diabetic individuals and demonstrated modest improvements in body weight, glycaemic control and blood pressure. Thus, mindfulness meditation-based intervention can lead to improvements across all domains of holistic care – biological, psychological and social. Though most of these studies have been of short duration and included small numbers of patients, meditation strategies can be useful adjunctive techniques to lifestyle modification and pharmacological management of diabetes and help improve patient wellbeing.

Authors: Hadimani Chetana P. , Kulkarni Shruti S. , Math Avinash K. , Javali Shivalingappa B.
Published: May 2018

Background: The public health burden of a sedentary lifestyle has been recognized globally. Physical inactivity has been identified as the fourth leading risk factor in global mortality. Medical professionals have a significant role in counselling patients so as to reach the public health goals. The objectives were to evaluate patterns of physical activity comprising work, transport, domestic and leisure domains and its correlation with gender and body mass index (BMI) among medical students.Methods: A cross-sectional study was conducted in 128 medical students. The international physical activity questionnaire (IPAQ) long form was used to measure total physical activity (PA) and metabolic equivalent (MET). BMI was calculated using height and weight. Data analyzed by SPSS version 20.Results: It was observed that the PA was low among medical students. As per MET score, 80.5%, 58.6%, 67.2% and 39% of students had a low PA pattern in domains of work, transport, domestic and leisure time respectively. The practice of domestic and leisure activity was significantly lower among female students compared to males with p-values of <0.009 and 0.005. The association between PA score and its domains with BMI of students was found to be not significant. In female students a significant positive relationship was observed between domestic and BMI scores with r =0.3459, p<0.005.Conclusions: Medical students in this study were insufficiently physically active. The practice of activity was intensely lower in females compared to males. These results reflect us the crucial need for intervention on students’ health promotion strategies.
An assessment of physics laboratory teaching and learning resources in two Nigerian universities
Authors: Ogunleye Ayodele , Anyaegbuna Benjamin E
Published: May 2018

It is hard to imagine learning science without doing laboratory or fieldwork. The research work in this paper assessed the state of physics laboratory teaching and learning resources in some selected universities in the South West geopolitical zone of Nigeria. The survey was carried out in five universities namely The University of Lagos, University of Agriculture, Lagos State University, Olabisi Onabanjo University and Covenant University. An 88-item inventory assessment questionnaire was administered and responses were collated for analysis. Descriptive statistics were used to analyse the data derived from the study. Findings revealed that there is dearth of modern and specialised physics laboratory equipment/resources; and the obsolete state of most workshops. Inadequacy of the available resources was also observed where some universities combine physics students from the Faculties of Education and Science for most practical sessions. Based on the findings, the study proffers some recommendation that could improve the resource situations in these universities.

Keywords: Physics, laboratory, learning.

Authors: Sardohan Yildirim Adile Emel , Akcamete Gonul
Published: May 2018

Individualised education programmes (IEP) will be practiced with children with special needs (CWSN) and their families. The main factor for IEP’s success is the participation of the family and also, their children. In this study, views and suggestions about participation of families of CWSN in their IEP processes are examined. The research is based on qualitative research. Five mothers and a grandmother with CWSN were participated; data are collected via semi-structured interview technique and analysed with inductive analysis technique. This research uncovers that the participants didn’t participate in their children’s diagnosis, assessment, settlement and follow-up processes, and they were not content with the assessment results. Also, the participants who didn’t participate in the IEP weren’t even aware of the legal obligation that they had to and their children’s IEP, they weren’t in cooperation with the teacher in that process, and teachers didn’t show the progress in the children to the families even if they recorded that.

Keywords: Children with special needs (CWSN), family, individualised education programmes (IEP).

Authors: Koseoglu Pınar , Pehlivan Hulya
Published: May 2018

The purpose of the study was to identify and analyse high school students’ metaphorical perceptions of biology and biology teacher concepts. The sample comprised all the 515 students studying in the Etimesgut district in Ankara in the spring semester of the 2015/2016 academic year. The data were gathered through a form which included the phrases ‘Biology/the biology teacher is similar to/the same as…, because…’ The data for the research were collected through qualitative research methods. The research approach adopted was phenomenological. Content analysis was used for the data analysis. According to the results, high school students use different metaphors to describe the biology concept. These metaphors are united under different conceptual categories in terms of their common qualities. The study results show how metaphors can be used as an important research tool in understanding and explaining the perceptions of students towards biology and biology teacher.
Keywords: Biology, biology teacher, metaphor, metaphoric thought, phenomenological research.

Published: May 2018

Bireyler yaşamları boyunca korku, kaygı ya da stres yaratacak pek çok problemle karşı karşıya kalabilirler. Bu durumlarında bireylerin kullandıkları başa çıkma stratejileri farklılık gösterir. Bazıları problemle doğrudan ilgilenerek çözüm yolları ararken, bazıları görmezden gelerek problem durumdan uzaklaşmayı tercih ederler. Ancak her durumda bireylerin kullandıkları bu stratejiler, yetişkinlikteki rollerini etkileyecek güce sahiptir. Bu bağlamda erken yaşlarda çocukların problem durumlarında kullandıkları stratejilerin belirlenmesi önemlidir. Bu araştırmanın amacı okul öncesi dönemdeki çocukların problem durumunda kullandıkları baş etme stratejilerinin belirlenmesidir. Nitel araştırma yöntemlerinden biri olan örnek olay yöntemi kullanılan bu araştırmanın çalışma grubunu Kars il merkezindeki MEB’e bağlı bir okul öncesi eğitim kurumuna devam eden 32 çocuk oluşturmaktadır. Araştırmanın verileri Ferit Avcı’nın “Kırmızı Fili Gördünüz mü?” kitabı kullanılarak elde edilmiştir. Çocuklardan bu kitabın sonunda yer alan problem duruma ilişkin çözüm önerileri üretmeleri istenmiştir. Bu problem karşısında çocukların kullandıkları stratejiler, aktif-bilişsel, aktif-davranışsal ve kaçınmacı başa çıkma stratejileri kategorilerine göre incelenmiştir. Çocukların problem durum karşısında aktif-davranışsal stratejiyi diğer stratejilere göre daha fazla tercih ettikleri belirlenmiştir. Eğitim akışında yer verilecek olan etkinlikler aracılığıyla çocukların bu stratejileri tanıması, deneyimlemesi ve değerlendirmesi sağlanabilir.

Mutual fund herding behavior and investment strategies in Chinese stock market
Authors: Wei-Shan Hu John , Lee Yen-Hsien , Chen Ying-Chuang
Published: May 2018

This investigation studies the impact of mutual fund herding on the returns achieved by contrarian strategy from 1990 to 2015 in the Chinese stock market. The relationship between the profit gained by the contrarian strategy and the macroeconomic environment is also examined. First, the returns of the contrarian strategy in China’s stock market are found to be significant. Second, most loser stocks with a high degree of mutual fund herding outperform loser stocks with a low degree of mutual fund herding, revealing that the profitability of an investment portfolio depends on the degree of mutual fund herding. Third, investors should buy loser stocks with a high degree of herding and sell winner stocks with a low degree of herding during a two-year formation period, over which zero-cost contrarian strategies yield the significantly highest return. Finally, the payoff of contrarian strategies is positively related to the herding effect and negatively related to macroeconomic variables.

This paper discusses the effects of inter-ethnic conflict in 1999 on the social life in Sambas. Therefore, any effort dealing with post-conflict situation is needed, through the concept of Islamic character education to modify the Besaprah local wisdom in Malay-Sambas society. This study used a qualitative method with an ethnographic approach which tries to interpret the phenomena in Sambas society since the post-conflict of Malay-Madura in 1999. The research findings show that the inter-ethnic conflict in Sambas, West Kalimantan, occurring in 1999 led to some problems, i.e. moral and social problem, as well as the crisis of local wisdom values. Accordingly, empowering local wisdom values in Besaprah tradition has a contribution to Islamic education concept as it gives an alternative solution to cope with negative effects of the inter-ethnic conflict.

The discrimination suffered by Rohingya Muslims is increasingly blewed up in media in last decade. The peak of the discriminatory treatment against Rohingya Muslim by Myanmar government is the unavailability of shelter from Myanmar government. In the perspective of international law, Myanmar government's actions constitute a serious violence, because it ignores the rights of its citizens. Even a series of massacres and inhumane treatment became a major offense committed by Myanmar government in terms of humanity. This attracted international attention in solving the problem. This article illustrated the fate of Rohingyas who are not given citizenship rights by Myanmar government. It also revealed the irony of Muslims of Rohingya life who are discriminated by the government of Myanmar, both in the practical as well as in the political context.

Diskriminasi yang diderita oleh Muslim Rohingya semakin mengemuka di media dalam dekade terakhir. Puncak perlakuan diskriminatif terhadap Muslim Rohingya adalah tidak tersedianya tempat tinggal dari pemerintah Myanmar. Dalam perspektif hukum internasional, tindakan pemerintah Myanmar ini merupakan bentuk kekerasan yang serius, karena mengabaikan hak warganya. Selain itu serangkaian pembantaian dan perlakuan tidak manusiawi menjadi pelanggaran besar yang dilakukan oleh pemerintah Myanmar dalam hal kemanusiaan. Hal ini menarik perhatian dunia internasional dalam upaya memberikan solusi atas permasalahan-permasalahan tersebut. Artikel ini selain menggambarkan nasib warga Rohingya yang tidak diberikan hak kewarganegaraan oleh pemerintah Myanmar, juga mengungkap ironi Muslim dari kehidupan Rohingya yang didiskriminasi oleh pemerintah Myanmar, baik dalam praktik maupun dalam konteks politik.

O fenômeno da informalidade tem impacto relevante na economia dos países, principalmente na economia de países em desenvolvimento como o Brasil. Assim, o presente trabalho tem como objetivo fazer um diagnóstico da economia informal no município de Machado/MG. Para tanto, foi realizada uma pesquisa qualitativa, com método de bola de neve (Biernacki; Waldorf, 1981), utilizando entrevistas estruturadas. Posteriormente, fez-se uma análise de conteúdo (Bardin, 1977). Foram realizadas 107 entrevistas com os proprietários de negócios atuando na informalidade, os quais, em sua maioria, são de propriedade de homens, com idade entre 40 e 59 anos, com baixa escolaridade, sendo esta sua única atividade remuneratória. Apesar de terem interesse em se formalizar, os indivíduos citaram que os elevados custos com impostos e o tamanho do negócio fazem com que se mantenham na informalidade. Conclui-se que a economia informal é um ambiente complexo, possuidor de aspectos tanto positivos, como o fato de flexibilizar o trabalho das pessoas para que estas possam ter mais tempo para a família, quanto negativos, quando não consideram o incentivo ao crescimento e à eficiência.

O objetivo deste artigo é identificar a influência dos fatores antecedentes do uso da pesquisa operacional (PO) como ferramenta estratégica nas organizações. Para tanto, foram propostas variáveis dependentes em relação ao seu uso: expectativas de benefícios; frequência de uso; e capacitação do usuário. A fase empírica analisou as respostas de executivos-chave de 171 empresas. A análise dos dados foi realizada por meio da análise fatorial exploratória e pela modelagem de equações estruturais, com a estimativa por meio dos mínimos quadrados parciais. Como resultado, identificou-se que a pesquisa operacional ainda é utilizada de maneira incipiente nas empresas e que, apesar de os executivos reconhecerem o potencial dos benefícios do uso da pesquisa operacional como ferramenta estratégica, a falta de capacitação dos usuários e a baixa frequência de utilização dessa ferramenta ainda se mostram como fatores limitadores de seu uso.
Device Applications of Metal-2D-Materials Interfaces A Short Review

Published: May 2018

The electronic energy band gaps of 2D-materials are known to spread over a wide range from zero in graphene to > 6eV in hexagonal boron nitride (h-BN). Various combinations of such engineered nanomaterials offer a number of novel device applications involving their unique optical, electronic, and thermal properties along with their higher charge carrier mobilities and saturation limited drift velocities. Structurally, these nanomaterials have single or multiple monolayers stuck together, which are not only suitable for flexible electron devices and circuits but also in preparing heterostructures (lateral as well as vertical configurations) that form super lattices with different kinds of band alignments. Such possibilities offer flexible control over the charge carrier transport in these materials via numerous types of exciton formations. Their extra sensitivity towards the presence of atomic, molecular and nanoparticulate species in their vicinity is the most significant aspect of these 2D-materials. This is the reason behind studying them in detail for detecting the presence of extremely low concentrations of the analyte that are not achievable in conventional sensors. For translating the above-said superlative properties of these fast emerging families of 2-D nanomaterials into usable devices and circuits, applying the conventional device fabrication technologies poses a real challenge. The experimental results reported in the context of forming usable interfaces between a metal and 2D-nanomaterial are examined here to assess their current status and future prospects. Their widespread applications are certainly anticipated in the fields like printed micro/nano sensors, large area electronics and printed intelligence with special reference to their emerging usages in Internet of Things (IoT) in the near future.

The purpose of safety designing is generally not on cost, but rather on saving life and nature, and consequently bargains just with specific risky system failure modes. High reliability levels are the consequence of good designing, scrupulousness and dependably never the aftereffect of re-dynamic failure management. Failure mode and effect analysis (FMEA) is a helpful technique analyzing engineering system reliability. The study focused on the use of FMEA technique to analyze the reliability of engineering equipment or components in selected areas such as: Wind Turbine component, Manufacturing Industries, Medical field and in evaluating the performances of Robots in different fields. The study showed the importance of FMEA as used widely in analyzing engineering equipment with regards to reliability.
