Reformas educacionais e avaliação: mecanismos de regulação na escola
Authors: Grego Sonia Maria Duarte
Published: June 2015

A preocupação central foi investigar as formas e racionalidades implícitas de regulação social/autonomia dos processos de gestão da aprendizagem, historicamente estabelecidas nas reformas educacionais de 1971 até 1982, via diretrizes de avaliação do rendimento escolar, no Estado de São Paulo. Utiliza-se abordagem sócio-histórica, tendo como fonte primária os discursos e documentos oficiais e como fontes secundárias os trabalhos e pesquisas sobre avaliação e trabalho docente. Tomam-se como categorias centrais a continuidade e ruptura nos padrões e mecanismos de regulação social/autonomia do trabalho educativo. Os resultados contribuem para esclarecer como as políticas educacionais, instituídas em contextos de reprodução/transformação social, condicionam a gestão dos processos educativos no interior da escola.
O estágio supervisionado para além de uma atividade curricular: avaliação e proposições
Authors: Calderano Maria da Assunção
Published: June 2015

Tendo por base reflexões específicas sobre a formação docente são apresentadas algumas experiências desenvolvidas em diversos estados da federação brasileira, bem como em outros países da América Latina, como Argentina, Chile e Colômbia. Tais reflexões têm como propósito abrir espaço para focalizar o estágio curricular, identificado como uma problemática, que ficou e ainda tem ficado, muitas vezes, à deriva nos cursos de formação docente. Neste texto, serão apontados traços comuns e díspares, presentes no desenvolvimento dos estágios curriculares nos cursos de licenciatura, revelando a complexidade da concepção teórica e metodológica que os sustenta. Apoiando-se também em pesquisa empírica, depoimentos de professores e alunos são apresentados e, ao final, destaca-se a necessária reconstituição de uma concepção de estágio curricular institucional, para que este se torne não apenas um componente curricular obrigatório, mas uma estratégica didático-pedagógica e política.
Avaliações externas e qualidade na educação básica: articulações e tendências
Authors: Alavarse Ocimar M. , Bravo Maria Helena , Machado Cristiane
Published: June 2015

Neste artigo aborda-se a implantação de sistemas municipais de avaliação em quatro municípios paulistas. São destacados elementos da avaliação de sistema que evidenciam sua articulação com a valorização da qualidade do ensino em diferentes concepções. Os resultados obtidos pelas redes que compõem o escopo do estudo e os contornos de seus sistemas próprios de avaliação são realçados para demonstrar possíveis incrementos na qualidade do ensino. Por fim, conclui-se que a avaliação externa, concebida como um processo amplo que envolve escolhas técnicas, políticas e ideológicas, é um importante instrumento para o acompanhamento de alunos e escolas e a tomada de decisões. Porém, além de se enfatizar a necessidade de novos estudos em face das tendências constatadas, recomenda-se cautela para afastar eventuais efeitos negativos, como transferência de responsabilidades e comprometimento da qualidade de seus próprios resultados.
Avaliação externa da escola: repercussões, tensões e possibilidades
Authors: Amaro Ivan
Published: June 2015

O artigo discute as repercussões e as tensões geradas pelas avaliações externas em escolas municipais da Baixada Fluminense - RJ. A pesquisa se concentra na problemática do acesso, análise e compreensão dos resultados do Índice de Desenvolvimento da Educação, bem como de seus impactos nos sistemas e nas escolas. As análises preliminares, coletadas por entrevistas, apontam para a identificação de impactos na organização escolar e no trabalho pedagógico docente com características neotecnicistas, gerencialistas e reguladoras, o que é visto como preocupante. Apesar de nossa análise crítica, as avaliações externas também podem se revestir de possibilidades ancoradas no conceito de qualidade negociada.

Authors: Serpa Alexandre Luiz de , Pontes Luís Antônio Fajardo
Published: June 2015

A violência é um problema endêmico no Brasil, em suas mais distintas formas. Nas escolas, essa realidade não é diferente, sendo o bullying uma das expressões de violência que mais têm chamado a atenção nos últimos anos. Este artigo descreve e analisa a frequência e a intensidade de ocorrência de práticas de bullying em escolas do ensino básico do Estado de São Paulo e explora, por meio de modelos de regressão logística, a associação entre o bullying e as características contextuais e o desempenho acadêmico dos alunos. Para isso, utiliza dados do questionário de fatores contextuais e dos testes de Língua Portuguesa e Matemática aplicados aos alunos na edição de 2009 do Sistema de Avaliação de Rendimento do Estado de São Paulo. O trabalho aponta a existência de um número considerável de vítimas de práticas intensas de bullying no Estado de São Paulo e identifica um conjunto de características dos alunos, que estão fortemente associadas a uma maior vulnerabilidade a essas práticas.
Avaliação da aprendizagem no curso de nutrição
Authors: Schwarz Kélin , Paixão Priscilla Campiolo Manesco
Published: June 2015

O estudo objetivou investigar as concepções de avaliação da aprendizagem da forma como são percebidas por alunos e professores do curso de Nutrição de uma universidade pública do Paraná, bem como outras questões importantes referentes às práticas avaliativas. O estudo foi realizado por meio de questionários aplicados a professores e alunos, e as respostas foram agrupadas para a análise. Os resultados revelaram que a concepção de avaliação da aprendizagem para grande parte de alunos e professores foi semelhante e caracteriza-se como um instrumento para verificar o que o aluno assimilou. A prova foi o instrumento avaliativo relatado como o mais utilizado por todos os professores pesquisados, sendo geralmente associado a outros instrumentos avaliativos. Assim, enfatizam-se a necessidade e a importância de se repensar constantemente o significado da avaliação da aprendizagem, além da necessidade de capacitar continuamente professores e gestores do ensino superior, para que a avaliação realmente contribua para construção do conhecimento.

O estudo centrou-se na análise de documentos oficiais que versam sobre avaliação do desempenho docente emitidos pelo Ministério de Educação e Ciência de Portugal no período de 2009 a 2012. Parte-se do pressuposto de que tais documentos respondem a uma política oficial de avaliação docente de cunho somativo e meritocrático, cujos padrões de desempenho revelam uma política nacional de controle, orientação, monitoramento, supervisão do trabalho dos professores que se reflete na profissionalização docente.
Avaliação na educação infantil: um debate necessário
Authors: Neves Vanessa Ferraz Almeida , Moro Catarina
Published: June 2015

Nosso objetivo é contribuir com o debate acerca dos processos de avaliação na educação infantil, tema pouco presente em nossa produção acadêmica. Entendemos que é necessário avançarmos na discussão do processo de avaliação interna às instituições. Recorremos a pesquisas e documentos nacionais que enfocam a avaliação na primeira etapa da educação básica, bem como apresentamos dados do processo avaliativo em uma instituição de educação infantil em Belo Horizonte. Concluímos que, nos momentos de avaliação, as práticas educativas das professoras tornam-se ainda mais visíveis, assim como suas concepções a respeito das crianças. O desafio permanece no sentido de continuarmos esse debate com base em um referencial que nos ajude a construir formas de avaliação que, de fato, orientem práticas educativas que respeitem a criança como sujeito de direitos.
Dilema moral na educação infantil: generosidade ou justiça?
Authors: Kawashima Rosana Akemi , Martins Raul Aragão
Published: June 2015

O objetivo deste trabalho é investigar os juízos a respeito da virtude generosidade ou justiça de professores da educação infantil e compará-los com os das crianças. Foram entrevistados 26 professores e 90 crianças de 4, 5 e 6 anos de idade desse nível de ensino. O instrumento utilizado foi um dilema moral em que a protagonista da história teria de optar entre dar um prêmio para a criança que fez o desenho mais bonito (justiça) ou para a criança que estava triste (generosidade). Os resultados indicam que a justiça é a virtude mais valorizada pelas professoras e que já é valorizada pelas crianças, podendo ser uma necessidade para elas. E a generosidade é mais valorizada pelas crianças do que pelas professoras.

Incongruências no discurso sobre qualidade da educação brasileira
Authors: Bautheney Katia Cristina Silva Forli
Published: June 2015

Este artigo analisa, por um viés foucaultiano, as incongruências do discurso sobre qualidade da educação no Brasil a partir de dois instrumentos de aferição: o Índice de Desenvolvimento da Educação Básica e o Programa Internacional de Avaliação de Estudantes. Apesar do destaque para a necessidade de melhoria dos processos de escolarização, com avanço de discussões e sua constante inserção na agenda das políticas públicas em diversas esferas, o próprio sistema cria ciladas que podem comprometer a sua viabilização. Quando se simplifica a questão, por uma ênfase discursiva na mensuração do desempenho de alunos, corre-se o risco de responsabilizá-los (bem como a seus professores e a suas escolas), obliterando o dever do Estado em garantir uma educação de qualidade. Tal movimento é reforçado por uma leitura psicologizante do desenvolvimento e apresenta-se como um mecanismo de segregação e exclusão pedagógica.
Avaliação de professores: uma questão de escolhas
Authors: Cassettari Nathalia
Published: June 2015

O artigo apresenta uma revisão da literatura sobre a avaliação de professores, destacando os diferentes objetivos, critérios e instrumentos que podem ser utilizados na construção de novas propostas. As alternativas disponíveis refletem concepções muitas vezes divergentes, o que pode repercutir em enfrentamentos durante o processo de tomada de decisões. Ainda assim, é grande o consenso em relação à necessidade desse processo ser o mais participativo possível, sendo ressaltada a importância do envolvimento dos professores. Outro consenso encontrado na bibliografia refere-se à superioridade das iniciativas que empregam mais de um instrumento avaliativo, possibilitando uma análise mais completa do trabalho docente.

Published: June 2015

Este artigo busca identificar, com dados do Enade (Exame Nacional de Desempenho de Estudantes) 2011 e por meio de modelagens hierárquico-lineares, fatores associados ao desempenho dos novos engenheiros formados no Brasil. Objetiva-se fornecer aos gestores das instituições e aos formuladores de política de ensino superior indícios sobre o que se mostra mais relevante na formação nas engenharias, principalmente no que concerne a fatores suscetíveis à tomada de decisão. Os resultados reforçam a percepção geral de que cursos seletivos de instituições públicas se destacam na formação de engenheiros, mas também apontam a importância, em muitos cursos, da disponibilidade do professor para atendimento fora do horário de aula. Na média, aferiram desempenho melhor os alunos que cursaram o ensino superior na idade correta e que fizeram o ensino médio em escolas públicas, os alunos do sexo masculino e os que se declararam brancos.
Avaliação de aulas por crianças: reflexões sobre suas aprendizagens
Authors: Lima Juliana de Melo , Leal Telma Ferraz
Published: June 2015

O objetivo deste estudo foi analisar quais tipos de aprendizagens foram valorizados por estudantes que participaram de uma sequência didática com o gênero reportagem. Com base na perspectiva sociointeracionista de ensino da língua, defendemos a avaliação na perspectiva formativa-reguladora, focando o aluno como agente da avaliação. Foram observadas 23 aulas de duas professoras e realizadas entrevistas com 51 estudantes. Foram identificados seis tipos de respostas relativas aos conteúdos/habilidades apreendidos (aprendizagens efetivadas), sendo quatro mais relacionados aos eixos do ensino da língua e dois mais gerais, relativos à ampliação de conhecimentos e à aprendizagem da importância de aprender. Observamos que as crianças refletiram sobre suas próprias aprendizagens e avaliaram de forma relevante os conhecimentos apropriados e habilidades desenvolvidas durante a sequência.

Authors: Cerdeira Diana Gomes da  Silva , Almeida Andrea Baptista de , Costa Marcio da
Published: June 2015

Este artigo analisa oito grupos focais, dos quais participaram 27 gestores escolares e 36 professores das redes municipais de ensino dos municípios vizinhos Rio de Janeiro e Duque de Caxias, no Estado do Rio de Janeiro. O objetivo é conhecer a percepção dos profissionais do ensino fundamental acerca das influências das avaliações externas no currículo escolar. Além de participar da Prova Brasil, ambos os municípios implementaram um sistema próprio de avaliação. O Rio de Janeiro tem uma política de bonificação salarial para os profissionais cujas escolas atingirem metas estabelecidas pela Prefeitura, ao passo que Duque de Caxias não promove políticas de alto impacto. Abordamos a discussão atual sobre as avaliações externas, bem como a discussão sobre o currículo nesse contexto. Ao final, problematizamos as abordagens que sugerem que as avaliações vêm constrangendo o trabalho docente e promovendo o estreitamento do currículo escolar.
The Cyclical Nature of Self-Regulated Learning Phases: Stable Between Learning Tasks?
Authors: Moos Daniel C. , Miller Amanda
Published: June 2015

Think-aloud and self-report data from 37 preservice teachers were used to examine the stability of self-regulated learning (SRL). Participants, all of whom were preservice teachers, learned about 2 topics (Circulatory System and Constructivism) with hypermedia. Think-aloud data were collected to determine the extent to which participants self-regulated their learning in each task. In addition, participants completed a self-report questionnaire, which measured various motivation constructs. Results indicated that the level of extrinsic motivation and control beliefs was similar between tasks, whereas the level of task value and self-efficacy was higher when participants learned about Constructivism. In addition, participants’ use of some SRL processes (planning and monitoring) was stable between the learning tasks, despite the higher level of task value and self-efficacy. Use of learning strategies significantly increased when they learned about Constructivism, however. These results offer theoretical implications and insights into the interaction between SRL phases during hypermedia learning.
Influence of Rotary-Steerable-System Design on Borehole Spiraling
Authors: Marck J.. , Detournay E..
Published: June 2015

The paper investigates the influence of the design of push-the-bit rotary-steerable systems (RSSs) on the tendency to drill spiraled boreholes by analyzing the directional stability of the bit trajectory. In this model, differences in RSS designs are accounted for conceptually by assigning a lateral stiffness to the RSS pads. This simple device, which introduces a dependence of the force on the pads upon the deflection of the bottomhole assembly (BHA) relative to the borehole axis, enables exploration of the influence of the actuation mechanism, with the RSS behaving at the ends of the spectrum either as a soft or as a stiff node of the drilling structure.

According to this analysis, low pad stiffness has little consequence on the general behavior of the system. However, as the pad stiffness increases, any perturbation in the borehole geometry sensed by the pads alters the drilling direction of the bit and triggers, under certain conditions, self-excited oscillations in the borehole geometry. By increasing the transverse rigidity of the BHA in the vicinity of the bit, stiff RSS pads thus enhance the propensity of a drilling structure to drill spiraled holes and generate, if the system is directionally unstable, borehole oscillations with pitch that corresponds to the distance between the bit and the pads. In contrast, a directionally unstable BHA equipped with RSS characterized by a low stiffness produces spiraled holes with a wavelength corresponding to the distance between the bit and the first stabilizer.
Removal of an azo dye (Orange G) from aqueous solution using modified sawdust
Authors: Banerjee Sushmita , Chattopadhyaya Mahesh C. , Chandra Sharma Yogesh
Published: June 2015

In the present study, modified sawdust was used for the removal of an azo dye (Orange G (OG)) from aqueous solutions. The study was carried out in batch mode. Effects of various important parameters such as pH, concentration, temperature, dose and agitation speed on the removal of the dye were investigated for optimization of the process. It was observed that the maximum removal of 78.3% was achieved at the lowest dye concentration of 50 mg/L. The process of removal was found to be exothermic in nature. Adsorption of OG on modified sawdust was rapid and in accordance with pseudo-first-order kinetics. Mass transfer coefficient (βL) was also estimated and found to be 0.33 cm/sec at 30 °C, which indicates that sorption of dye was driven by a film diffusion mechanism. The Langmuir isotherm model agrees well with the sorption isotherm data and also confirms that adsorption took place on the homogenous surface of modified sawdust. The Langmuir capacity was determined and found to be 5.48 mg/g. Therefore, the study recommends that modified sawdust is a promising candidate for the efficient removal of dye-contaminated wastewater.
Assessing factors that lead to use of appropriate technology handwashing stations in Mali, West Africa
Authors: Naughton Colleen C. , Sissoko Haoua Traoré , Mihelcic James R.
Published: June 2015

Proper hand hygiene is an effective and efficient method to prevent diarrheal disease and acute respiratory infections, and their resulting deaths, particularly for children under 5 years old. Despite this evidence, handwashing rates remain seriously low in the developing world. This study presents results of a mixed methods approach and comprehensive monitoring strategy of five use variables (use of soap, handwashing station functionality, presence of cleansing agent including soap or white ash, ground wetness, and amount of water in the jug) over 2 years for 42–64 appropriate technology handwashing stations located in two communities in Mali, West Africa. Six factors were studied as potentially critical for lasting use of handwashing stations (gender, educational training, water proximity, seasonality, wealth, and station adoption). Statistically significant (p < 0.05) results include: (1) a 29% decrease in use of soap between dry (October–June) and rainy seasons (July–September); (2) 35% decrease in stations with cleansing agent (e.g., soap or white ash) present over 1 year; (3) greater station use in wealthy households; (4) a 27% reduction in cleansing agent present for stations further from a water source during the rainy season; and (5) greater use of stations built by women in one community.

Published: June 2015

Introduction. Erdheim-Chester disease (ECD) is a rare, systemic form of
non-Langerhans cell histiocytosis of the juvenile xantho-granuloma family
with characteristic bilateral symmetrical long bone osteosclerosis,
associated with xanthogranulomatous extras-keletal organ involvement. In ECD,
central nervous system (CNS) and orbital lesions are frequent, and more than
half of ECD patients carry the V600E mutation of the proto-oncogene BRAF. The
synchronous or metachronous development of ECD and Langerhans cell
histiocytosis (LCH) in the same patients is rare, and the possible connection
between them is still obscure. Cladribine is a purine substrate analogue that
is toxic to lymphocytes and monocytes with good hematoencephalic penetration.
Case report. We presented a 23-year-old man successfully treated with
cladribine due to BRAF V600E-mutation-negative ECD with bilateral orbital and
CNS involvement. ECD developed metachronously, 6 years after chemotherapy for
multisystem LCH with complete disease remission and remaining central
diabetes insipidus. During ECD treatment, the patient received 5 single-agent
chemotherapy courses of cladribine (5 mg/m2 for 5 consecutive days every 4
weeks), with a reduction in dose to 4 mg/m2 in a fifth course, delayed due to
severe neutropenia and thoracic dermatomal herpes zoster infection following
the fourth course. Radiologic signs of systemic and CNS disease started to
resolve 3 months after the end of chemotherapy, and CNS lesions completely
resolved within 2 years after the treatment. After 12-year follow-up, there
was no recurrence or appearance of new systemic or CNS xanthogranu-lomatous
lesions or second malignancies. Conclusion. In accordance with our findings
and recommendations provided by other authors, cladribine can be considered
an effective alternative treatment for ECD, especially with CNS involvement
and BRAF V600E-mutation-negative status, when interferon-? as the first-line
therapy fails.

Published: June 2015

The Åstrand-Ryhming Submaximal Bicycle Test is an accurate and widely used test to estimate maximal oxygen consumption. This test requires a participant to maintain a workload over a 6-min. period. The issue facing many employing this protocol is the identification of an appropriate workload for the cycling regimen. The present study is designed to identify a method for determining an appropriate workload for female participants. A prior study designed a workload selection procedure specifically for men; however, the selection procedure designed for women in this study was better able to elicit a final heart rate (average of minutes five and six) between 165–170 bpm compared to the original Åstrand-Ryhming procedure.
Music Tempo's Effect on Exercise Performance: Comment on Dyer and McKune
Authors: Nakamura Priscila Missaki
Published: June 2015

Dyer and McKune (2013) stated that music tempo has no influence on performance, physiological, and psychophysical variables in well-trained cyclists during high intensity endurance tasks. However, there are important limitations in the methodology of the study. The participants' music preferences and tempo change were not well measured. It is not possible to affirm that music tempo does not influence athletes' performance. Potential areas of future research include: (a) use of instruments to assess the qualities of music; (b) standardizing music of tempo according to exercise type (e.g., running, cycling, etc.); (c) considering training level of the participants (i.e., athletes and non-athletes); and (d) use of instruments to assess concentration during exercise.
Silencing Sharapova's Grunt Improves the Perception of Her Serve Speed
Authors: Farhead Nader , Punt T. David
Published: June 2015

In recent years, grunting has become a familiar although generally unwelcome element of tennis. The behavior is considered to deny opponents the benefit of receiving optimal multi-sensory information in order to plan their own shots. The ability to make accurate serve-speed judgments of identical tennis serves presented on a computer screen, and accompanied by a grunt or not, was assessed among 38 participants (19 men). Accuracy and response time were measured. Analysis compared performance for below versus above average speed serves and for the grunt versus the no grunt condition. Grunting had a disruptive effect on serve-speed perception for below average serves, with most judged incorrectly to be above average. Response times for below average serves were also slower in the grunt condition. Grunting provides a complex perceptual challenge, and greater effort may be attributed to tennis serves with an accompanying grunt.

Kurzfassung

Nahezu alle Fertigungsverfahren führen durch inhomogene plastische Verformungen oder lokal unterschiedliche thermische Ausdehnungskoeffizienten zur Ausbildung von Eigenspannungen. Wenn diese aufgrund ihres Vorzeichens die Bauteileigenschaften ungünstig beeinflussen würden, müssen sie nachträglich abgebaut werden. Durch Einstellung geeigneter Prozessführungen können allerdings auch günstige Beeinflussungen der Bauteileigenschaften erreicht werden, sodass diese Prozessvarianten gezielt zur Optimierung von Bauteilzuständen, dem sogenannten Surface Engineering, eingesetzt werden können. Die Zusammenhänge zwischen dem Eigenspannungszustand sind Gegenstand der Arbeit. Dabei wird auf alle Hauptgruppen der Fertigungstechnik eingegangen.

Treatment of a cerebral pial arteriovenous fistula in a patient with sickle cell disease-related moyamoya syndrome: case report
Authors: Lo Presti Anna , Weil Alexander G. , Fallah Aria , Peterson Eric C. , Niazi Toba N. , Bhatia Sanjiv
Published: June 2015

Sickle cell disease (SCD) is an autosomal recessive hematological disorder, characterized by sickling of the red blood cells in response to a hypoxic stress and vaso-occlusive crises. It is associated with moyamoya-like changes on cerebral angiographic imaging in 43% of patients. Cerebral aneurysms, arteriovenous malformations, and dural arteriovenous fistulas (AVFs) have been described in association with SCD and moyamoya disease. However, the description of a pial AVF (pAVF) in a patient with SCD and/or moyamoya formation has not yet been reported. The authors present the case of a 15-year-old boy with SCD-associated moyamoya disease harboring a pAVF who developed a de novo venous aneurysm 8 months after undergoing indirect superficial temporal artery-middle cerebral artery (MCA) bypass that was complicated by bilateral ischemia of the MCA territory. The pAVF was successfully treated with transarterial embolization using Onyx. The authors describe the possible pathophysiological mechanisms and management strategies for this rare occurrence.

Published: June 2015

The experiment was conducted at the farmer`s field of Boyerchor, Hatia, Noakhali under On-Farm Research Division, Bangladesh Agricultural Research Institute (BARI), during the rabi seasons of 2011-2013 to study the effect of variety on the productivity of fenugreek in coastal saline soil. The experimental treatments included 3 varieties viz. V1= BARI Methi 1, V2 = BARI Methi 2, V3 = Local Methi. The experiment was laid out in a randomized complete block design with six dispersed replications. There was a strong varietal influence on crop growth and seed yield. Among the varieties, BARI Methi 2 showed the best results in terms of plant height, number of branches, number of pods and number of seeds pod-1 resulting in the highest seed yield of 1497 kg ha-1. It was also observed that plant mortality of fenugreek was highly affected at germination stage when the soil salinity was above 4 dSm-1. However, at the later stages of crop growth up to the maturity, the salt tolerance of the crop was higher varying from 4-12 dSm-1. It was indicated that critical range of salinity level for cultivation of fenugreek was 3.42-12.2 dSm-1 from germination till to maturity. Among the fenugreek varieties, BARI Methi 2 offered the highest net return of Tk. 50150 coupled with a benefit cost ratio of 3.03. Though total cost was the same, BARI Methi 2 showed higher BCR (3.03) over BARI Methi 1 and local Methi due to yield differences. The Agriculturists 2014; 12(2) 18-23
Impact of Lined Canal on Shallow Tubewell Irrigation and Their Acceptability by the Farmers
Authors: Sayed Abu , Saleh A F M , Hossain Md. Altaf , Basunia Zobayer Ali , Hosain Md. Afzal
Published: June 2015

The comparative conveyance losses between lined and unlined canals, impact of water saving on command area development and irrigation cost, and farmers acceptability of lined canal in shallow tubewell (STW) irrigation schemes were studied during 2010-11 Boro season at three upazilas: Manikgonj Sadar of Manikgonj district, Dhamrai of Dhaka district and Mithapukur of Rangpur district. The conveyance loss was measured using inflow-outflow method and focus group discussion (FGD) was carried out with the pump owners and farmers to assess the impact of water saving on command area development and the acceptability of lined canal technology. Average conveyance losses were found to be 41, 48 and 45% in the existing earthen canals; 18, 21 and 24% in improved earthen canals; and 12, 11 and 13% in pre-cast canals at Mithapukur (M1), Manikgonj Sadar (M2) and Dhamrai (D) schemes, respectively. The water saving did not increase the command area in any of the schemes but reduced the irrigation time and saved fuel requirement for irrigation. On an average, 32, 23 and 30% fuel were saved by improved earthen canals where as 45, 46 and 48% were saved by pre-cast canals for M1, M2 and D schemes compared to earthen canal. The benefit-cost ratios of improved earthen canals were 1.36, 1.38 and 1.30 where as 3.36, 4.28 and 3.34 by pre-cast canals for M1, M2 and D schemes, respectively. The internal rate of return (IRR) from the investment on water distribution was over 50%. The lining technology was acceptable to pump owners, but did not impress the farmers who share the crop with the pump owners as price of irrigation or pay on the basis of irrigated area. In order to make the technology acceptable to the farmers, polices must be framed to share the benefits of lining by the pump owners with the farmers by reducing the price of irrigation water or through financial support of GO and NGOs for efficient use of STW irrigation system in Bangladesh.The Agriculturists 2014; 12(2) 116-125

It is well established that Technetium99mmethylene diphosphonate (Tc99m MDP) whole body bone scintigraphy (WBBS) can demonstrate multiple lesions with increased radiotracer concentration in involved bone. But it is hard to differentiate multiple benign osteolytic lesions from disseminated bone metastases. Even combined with medical history and multiple imaging results, clinical diagnosis of metastatic lesion remains a challenge. This can affect the treatment procedure. Here the role of skeletal scintigraphy in a case of eosinophilic granuloma is evaluated and concluded that additional attention should be given before diagnosing any case as bone metastases.

Published: June 2015

A cross sectional study on Fasciola gigantica and Gigantocotyle explanatum burdens in buffaloes in relation to their age, sex and health condition was carried out in the Laboratory of Parasitology, Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from June to November 1997. A total of 460 faecal samples were examined to determine the egg per gram of faeces (epg) of F. gigantica. Higher epg was counted in female buffaloes (159.67 ± 6.80) than in males (153.24 ± 8.29). The epg counts were also found significantly (p < 0.01) higher in poor conditioned buffaloes (164.41 ± 6.67) than in buffaloes with normal health (128.57 ± 7.08). In relation to age, the young adult buffaloes were found to bear more parasitic burdens. The highest mean epg was recorded in the buffaloes of 2-3 years old (184.21 ± 19.14), followed by 3-5 years old (169.23 ± 30.77). The older buffaloes had relatively lower parasitic burden and the lowest mean epg was recorded in the growing buffaloes of up to 1 year old (125 ± 25.0). Examination of 106 livers from slaughtered buffaloes, revealed that the load of Fasciola gigantica and Gigantocotyle explanatum in the livers ranged from 13-424 (69.20 ± 6.46) and 41-427 (161.45 ± 10.79) respectively. In males the burden of F. gigantica (13-210) was lower than that of the females (15-424). The mean number of F. gigantica in the buffaloes of 5- 10 years old (100 ± 15.32) was significantly higher (p < 0.01) than those of the buffaloes of above 10 years old (52.92 ± 4.29). In case of single infection with F. gigantica, the mean number of parasites per liver was significantly (p < 0.05) higher (88.70 ± 11.48) than that of mixed infection cases (49.74 ± 4.20). Significantly (p < 0.01) higher number of G. explanatum was recovered from the buffaloes of 5-10 years old (207.53 ± 26.72) than from the buffaloes of above 10 years old (141.58 ± 9.23) and from single infected cases than from buffaloes with mixed infection. There were almost no differences in the number of both flukes in relation to sex of buffaloes. The length and breadth of immature and mature parasites were 5-15 min x 2-3 min and 16-72 mm x 4-14 mm respectively. No significant variation was found in the average size of F. gigantica in relation to the age and sex of buffaloes. But in case of single infection, the body size of mature F. gigantica (38.63 mm ± 0.38 mm x 9.96 mm ± 0.12 mm) was significantly (p < 0.05) higher than that of the mixed infection (33.68 mm ± 0.52 mm x 8.76 mm ± 0.07 mm) cases. This study fairly suggests that the young adult buffaloes harbour more F. gigantica parasites than their younger and older counterparts. The concomitant infection of buffaloes with F. gigantica and G. explanatum may hamper the parasites each other in establishing their infection and attaining growth in some way as measured by their burdens and morphological dimensions.

The present study was a cross-sectional type of descriptive one carried out with the objective of determining the diagnostic accuracy of imprint cytology and frozen section of central nervous system tumors. A purposively selected sample of 33 clinically diagnosed patients with CNS tumors has been included for the study. The relevant data on CNS tumors were collected by using imprint cytology, frozen section and paraffin section. The sensitivity of imprint cytology was 75.0% and specificity was 55.17% respectively. On the other hand positive predictive value of imprint cytology was 18.75% and negative predictive value was 94.11%. The sensitivity of frozen section was 100% and specificity was 86.21% respectively. Comparing the findings of the frozen section to histopathology, the positive predictive value was 50.0% and negative predictive value was 100%. The sensitivity and specificity of imprint cytology was lower in comparison to frozen section and paraffin section. Still then imprint cytology is preferred, because it can be carried out rapidly and easily. It will also be a very helpful aid especially when facilities for frozen section are limited but neurosurgical-procedure is available. A well designed research with adequate sample size should be carried out to get better diagnostic accuracy of imprint cytology in central nervous system tumors.Faridpur Med. Coll. J. 2014;9(1): 24-27

Snakebite is one of the important cause of mortality in our country. This study was carried out to see the common type of snakes in local area with clinical presentations, complications and outcome of snake bite patients inFaridpur. Fifty cases of snakebite patients in medicine wards of Faridpur Medical College Hospital from 1st January 2012 to 31th April 2013 were studied. Among 50 snake bite patients 35 (70%) were male and 15 (30%) were female. Among them 30 (60%) were venomous and 20 (40%) snake bite cases were non-venomous.The common victims were farmers (53%) and housewives (13%). The bites were commonly encountered during rural foot walking (32%) followed by sleeping (15%). 55% were bitten during outdoor and agriculture related activities. 65% had sustained bite in lower limbs. The majority (82%) of the snakebites were observed during the month. Total 98% patients applied multiple tight tourniquets in the affected limb. A common local practice (seen in 85%) was to receive pre hospital treatment from 'Ohzas'. Among 30 poisonous cases, drooping of the upper eyelid, external ophthalmoplegia and brocken neck were the common features of poisoning. Among the 30 venomous snake bite cases 21 (70%) recovered completely after getting polyvalent antivenom serum and 9 (30%) died after admission. Total 80% cases recovered with 10 vials of polyvalent antivenom serum but others required upto 30 vials depending on severity of symptoms and its duration. No reaction to anti-snake venom was noticed.Faridpur Med. Coll. J. 2014;9(1): 32-34

Lung cancer is an important & widespread disease that contributes a major health problem worldwide. Lung cancer kills over 1 million people per year. Cigarette smoking is the major cause of lung cancer. CT scan is the principal radiological examination adjunct to X-Ray chest examination in diagnosis & management of lung cancer. The main Objective of the study was to assess the diagnostic usefulness of CT scan in evaluating & characterize the different types of lung tumors and to correlate CT findings of lung tumors with that of cytopathology. This study was carried out in the department of Radiology & Imaging, Dhaka medical college hospital, Dhaka during the period from 1st January 2007 to March 2008. It was a cross sectional study. Total 51 patients were selected conveniently, detailed history particularly symptoms related to lung tumors was carefully elicited to obtain maximum possible information regarding the illness. Possible diagnosis was established by the combination of history, physical examination, laboratory & radiological investigations. Then patients were underwent CT examination of lung. Cytopathological sample were obtained from the lesion by guided aspiration. Collected FNAC samples were send for cytopathology & collected reports were compared with CT scan reports. Sensitivity of CT to diagnose lung tumor was 97.4%, specificity 76.9% & accuracy 92.2 %.Faridpur Med. Coll. J. 2014;9(1): 37-41
Management of chronic kidney disease- an update
Authors: Ahammad Faruk
Published: June 2015

Chronic kidney disease (CKD) is a global public health issue demanding continuous improvement in its management. Different international groups and organizations have now achieved a good progress in its definition, classification (staging), treatment and referral criteria to nephrologists. In definition of CKD, "CKD is defined as abnormalities of kidney structure or function, present for at least three months with implications for health", the phrase "with implications for health" has been added at the end of the previous definition, which reflects the concept that there may be certain abnormalities of kidney structure or function that do not have prognostic consequences (for example, a simple renal cyst). At staging of CKD, grade 3 has been subdivided into G3a and G3b, according to whether the glomerular filtration rate (GFR) is (59 - 45) or (44 - 30) ml/min/1.73m2, respectively. Furthermore, albuminuria has been classified in any GFR grade, in to A1, A2 or A3 according to the albumin-creatinine ratio (ACR) in an isolated urine sample for values <3, 3-30 or >30mg/mmol, respectively. The term "microalbuminuria" has now been replaced by the term "moderately increased albuminuria". For GFR measurement Chronic Kidney Disease Epidemiology Collaboration (CKD- EPI) equation has been preferred than the Modification of Diet in Renal Disease (MDRD) study equation and new 2012 KDIGO guidelines consider the use of alternative formulas to be acceptable if they have been shown to improve accuracy when compared with the CKD-EPI formula. For detection of albuminuria ACR is preferred rather than conventional 24 hours urine albumin. The recommended BP control target is ?140/90mmHg (both diabetic and non-diabetic) if ACR <3mg/mmol and a stricter target is suggested, with BP ?130/80mmHg, (both in diabetic and non-diabetic) if the ACR is ? 3mg/mmol. Use of erythropoisis-stimulating agent (ESA) in anemia of CKD should be rational; to avoid its adverse effects like stroke, thrombosis or hypertension acceleration and hemoglobin goals should not exceed 11 g per dl. Treating dyslipidaemia in CKD with statins for all adults >50 years of age, irrespective of low density lipoprotien (LDL) cholesterol levels is recommended. Referral to nephrologist should be rational according to guidelines and at least one year prior to the start of renal replacement therapy (RRT).Faridpur Med. Coll. J. 2014;9(1): 46-52
The Event of Style in Shakespeare's Sonnets
Authors: Aquilina Mario
Published: June 2015

This essay brings to bear Jacques Derrida's thinking of the ‘event’ and the ‘signature’, specifically in his reading of Francis Ponge's poetry, on the work of style in selected sonnets by Shakespeare. It argues that rather than functioning exclusively as a trace of identification and ownership, the event of style depends on the countersignature of the readers to come in ways that disrupt the teleocratic thinking at the heart of attribution studies in the authorship question. Style has a key role in the authorship controversy. It serves as internal evidence that allows critics to make claims about the authorship of Shakespeare's oeuvre. However, style in the sonnets, while signing for the author, also defaces and dispossesses him in ways that are partly rooted in the epideictic tradition from which the sonnets stem and partly intrinsic to the logic or structure of style as an event.
Pedagogical practices in VET: between direct and indirect teacher approaches
Authors: Vestergaard Louw Arnt
Published: June 2015

This article deals with pedagogical practices on the basic carpentry VET programme in Denmark. On the basis of an anthropologically inspired study among carpentry students at two VET schools, the prime objective of analysis is to understand the various pedagogical practices from the students’ perspective. Various different teaching situations are analysed and discussed with regard to their impact on the students’ motivation for participation as well as development of independent reflection skills. My argument is that the students look to the teachers for active support in their professional development. Without this active teacher support, the students become disengaged and demotivated and risk dropping out. This is especially clear at the beginning of the programme.
Er stasjonsopplæring i videregående skole en metode som er egnet til å støtte yrkesfageleven i vurdering av egen læring?
Authors: Stousland Hanne , Witsø Hilde
Published: June 2015

Nasjonal og internasjonal forskning viser at elever som lærer å vurdere sitt eget arbeid, øker sitt læringsutbytte og blir mere motivert for læring. I denne artikkelen vil vi presentere en studie basert på intervjuer og observasjoner av lærere og elever i en videregående skole, Utdanningsprogram for teknikk og industriell produksjon. Vi undersøkte om stasjonsopplæring som undervisningsmetode kan bidra til bedre vurderingspraksis ved at det blir lagt til rette for elevens egenvurdering. Vår hensikt er å argumentere for at læreres strukturering av og samarbeid om en fastlagt metode for opplæring i yrkesfag er egnet til å støtte elevens evner og muligheter til å vurdere sitt eget læringsarbeid. Stasjonsopplæring er i denne sammenhengen en strukturert undervisningsmetode i yrkesfag der Kunnskapsløftets ulike læreplanmål for det aktuelle utdanningsprogrammet er brutt ned til konkrete arbeidsoppgaver knyttet til aktuelle lærefag.
