    Full Text Available OBJETIVO: os rápidos e contínuos avanços nas Ciências da Computação resultaram no aumento significativo do emprego de novas tecnologias em todos os níveis da sociedade. Na Ortodontia, radiografias e fotografias digitais já são usadas de forma rotineira. A utilização de modelos de estudo digitais vem sendo anunciada como o novo componente da documentação ortodôntica computadorizada. Como acontece quando uma nova tecnologia se torna disponível, o uso de modelos ortodônticos digitais tem gerado controvérsias. Alguns ortodontistas questionam a aplicabilidade de imagens tridimensionais em substituição aos modelos tradicionais de gesso, pois não há na literatura número relevante de estudos que tenham testado adequadamente tal tecnologia. Diante disso, o objetivo desse estudo foi testar a confiabilidade do uso de modelos dentários digitais como exame complementar ao diagnóstico ortodôntico. METODOLOGIA: três examinadores mediram a largura dos dentes permanentes, quatro segmentos dos arcos superiores e inferiores, distâncias intercaninos, distâncias intermolares, trespasses horizontal e vertical em modelos de gesso e em seus correspondentes digitais de seis pacientes, utilizando um paquímetro digital e o programa eModel, respectivamente. RESULTADOS E CONCLUSÕES: diante dos resultados, observou-se que todas as medidas avaliadas foram estatisticamente semelhantes nos dois tipos de modelos testados, com exceção das médias encontradas para a largura do dente 45 (pAIM: the fast and continuous advances in computer sciences have resulted in an increased usage of new technologies in all levels of the modern society. Orthodontics has also been influenced by this phenomenon. Digital radiographs and photographs have been commonly used in Orthodontics offices. Recently, digital study models have been advertised as the latest component of fully digitized orthodontic records. When a new diagnostic technology becomes available it may

    Full Text Available Atualmente o mercado de Sistemas de Desenho auxiliado por Computador (CAD, sofre extrema carência de processos automatizados de reconhecimento de fala. O surgimento de tecnologias de automação facilita no desenvolvimento de aplicações capazes de auxiliar nestes processos. Baseando-se nestas afirmações construiu-se um modelo utilizando tecnologias capazes de transformar fala em sinais digitais, sendo possível a interpretação por sofisticados computadores. Observando ausência de tais ferramentas, o presente trabalho busca uma proposta capaz de acrescentar mecanismos os quais possibilitem a criação de modelos tridimensionais usando tecnologias como servidores HTTP, dispositivos moveis, linguagens de programação Java e PHP, Computação Gráfica e linguagem de interpretação por blocos. Os resultados obtidos na confecção do presente trabalho corroboram com as necessidades atuais representadas na sociedade propondo sustentabilidade, acessibilidade, portabilidade e facilidade de comunicação.

    Full Text Available Este trabalho descreve a experiência da construção de uma cartilha do auto-exame ocular para portadores do HIV/AIDS e teve como objetivo desenvolver e avaliar as ações do referido auto-exame por intermédio da cartilha “Auto-exame ocular”. A testagem da cartilha foi feita por meio de grupos educativos e consulta de enfermagem, bimestralmente, seguida do exame oftalmológico. Ao nos apoiarmos nas idéias de NIETSCHE (2000, rotulamos esse material como uma tecnologia emancipatória pelo fato de trazer, a essa população, a oportunidade de se libertar de um estado de sujeição. Os resultados comprovam que os portadores de HIV/AIDS se sentem motivados a investigar problemas oculares, mas ainda falta incorporar, na vida cotidiana, o hábito de utilizar a cartilha. Mais do que oferecer passos seqüenciais para realizar a técnica do auto-exame ocular, apresentamos referenciais que auxiliam o desenvolvimento das potencialidades dos portadores do HIV/AIDS com vistas a trabalhar o autocuidado com o olho de forma dinâmica e com um aliado, o material educativo.

    Full Text Available Introdução: Os avanços biotecnológicos em associação com a pressão para substituir a experimentação animal impulsionam o desenvolvimento de modelos in vitro mais fisiológicos e preditivos da resposta in vivo. Objetivo: Discutir vantagens e limitações de modelos tridimensionais (3D de cultura de células. Método: Revisão da literatura na base PubMed utilizando os termos “3D culture”, spheroid, organoid, “organotypic culture”, “alternative model”, microfluidic, organ-on-a-chip e biotechnology, individualmente e em diferentes combinações. A pesquisa abrangeu o período de 1971 a 2017. Resultados: Ensaios tradicionais de cultura em monocamada, embora sejam amplamente utilizados, não reproduzem as interações célula-célula e célula-matriz extracelular, que criam gradientes físicos e químicos e controlam funções celulares, como sobrevivência, proliferação, diferenciação, migração e expressão de genes e proteínas. Modelos 3D de cultura de células são capazes de mimetizar um microambiente mais fisiológico. O número de publicações no período estudado reflete o crescente interesse científico no tema. Conclusões: Embora os modelos 3D tenham inequivocamente contribuído para as áreas de bioengenharia, morfogênese, oncologia e toxicologia, muitos desafios permanecem. O custo elevado de alguns destes modelos, reproduzir as características mecânicas, espaciais e temporais dos tecidos, assim como a necessidade de desenvolver protocolos padronizados devem ser considerados.

    Full Text Available BACKGROUND: Many clinicians and researchers in Brazil consider the Neurological Developmental Exam (NDE, a valid and reliable assessment for Brazilian school-aged children. However, since its inception, several tests have emerged that, according to some researchers, provide more in-depth evaluation of motor ability and go beyond the detection of general motor status (soft neurological signs. OBJECTIVES: To highlight the limitations of the NDE as a motor skill assessment for first graders. METHODS: Thirty-five children were compared on seven selected items of the NDE, seven of the Bruininks-Oseretsky Test (BOT, and seven of the Visual-Motor Integration test (VMI. Participants received a "pass" or "fail" score for each item, as prescribed by the respective test manual. RESULTS: Chi-square and ANOVA results indicated that the vast majority of children (74% passed the NDE items, whereas values for the other tests were 29% (BOT and 20% (VMI. Analysis of specific categories (e.g. visual, fine, and gross motor coordination revealed a similar outcome. CONCLUSIONS: Our data suggest that while the NDE may be a valid and reliable test for the detection of general motor status, its use as a diagnostic/remedial tool for identifying motor ability is questionable. One of our recommendations is the consideration of a revised NDE in light of the current needs of clinicians and researchers.CONTEXTUALIZAÇÃO: Muitos clínicos e pesquisadores brasileiros consideram o Exame Neurológico Evolutivo (ENE, um instrumento válido e confiável para crianças brasileiras em idade escolar. Entretanto, desde a sua criação, surgiram outros testes para uma avaliação mais profunda de habilidade motora, os quais vão além de detectar status motor geral em forma de sinais neurológicos leves. OBJETIVOS: Demonstrar os pontos fracos do ENE como teste de avaliação de habilidade motora para crianças de primeira série. MÉTODOS: Trinta e cinco crianças realizaram 7 itens

    Full Text Available INTRODUÇÃO: as limitações na avaliação quantitativa e qualitativa de deslocamentos cirúrgicos pelos métodos bidimensionais podem ser superadas através de tomografias volumétricas e ferramentas de imagens tridimensionais. OBJETIVOS: a metodologia descrita neste trabalho permite avaliar as mudanças nas posições de côndilos, ramos, mento, maxila e da dentição após a cirurgia ortognática através de tomografias computadorizadas de feixe cônico (Cone Beam Computed Tomography, CBCT antes e após o procedimento cirúrgico. MÉTODOS: são construídos modelos 3D que possibilitam superposições tendo a base do crânio pré-cirúrgica como referência, utilizando-se um método automático que identifica e compara a escala de cinza dos voxels de duas estruturas tridimensionais, eliminando a necessidade do operador marcar os pontos anatômicos. Então, as distâncias entre as superfícies anatômicas são computadas, no mesmo indivíduo, entre as duas fases. A avaliação das direções de deslocamento das estruturas é determinada visualmente pelos métodos de mapas coloridos e de semitransparências. CONCLUSÕES: conclui-se que a metodologia apresentada, que utiliza softwares de domínio público, mostra vantagens na avaliação longitudinal de pacientes ortocirúrgicos, quando comparada aos métodos radiográficos convencionais, uma vez que as imagens geradas não apresentam magnificações ou sobreposições de estruturas e a maioria dos passos são automatizados, o que torna os procedimentos de mensuração mais precisos, além de disponibilizar uma maior quantidade de informações ao clínico ou pesquisador.INTRODUCTION: Limitations of 2D quantitative and qualitative evaluation of surgical displacements can be overcome by CBCT and three-dimensional imaging tools.

  2. The Latin Matura exam

    2003-12-01

    Full Text Available In students' opinion the tasks of this year's Pre-Matura exam are neither too easy nor too difficult. 51 % of  the students claim that the translation from Slovene to Latin is the most difficult task, which is not surprising. The students have to recognise the appropriate grammatical constructions without the help of any comments. In this way they can show their autonomy in the use of  the language. Very high quality of the Latin Matura exam tasks can be clearly seen from graph 3. Namely, the students have quite different opinions on which task is the most difficult and which one the easiest. This means that each student can find the type of a task that suits them most and so they can excel in that particular area. At the oral part of the exam 46 % of the students would like to eliminate the grammar question, as they find it difficult to define grammar rules precisely, while they do not have any problems using them in a sentence. Quite surprisingly there are 20 % who dislike the question from culture and civilisation. Their main argument is that in this way they would be able to save a lot of time and so concentrate on other areas. According to the students, the good points of the Latin Matura exam are: a better insight into Latin language and Roman culture, and a good foundation for further study at the university. As far as the bad points of the exam are concerned, they mostly complain about the translation from Latin to Slovene, as they believe they do not have a lot of freedom in translating. They also wish there were more books with different types of  Matura exercises. Teachers mainly agree with their students, but they also pointed out a certain problem: it can be quite tempting to deal only with the topics appearing at the Latin Matura exam and eliminate all others. Namely, every teacher wants to prepare their students for the exam in the best possible way, as they feel their pedagogical and  professional skills are tested too.

    2013-04-01

    Full Text Available OBJETIVO: Avaliar o impacto da ranitidina por via oral na qualidade do exame de colangiopancreatografia por ressonância magnética (CPRM. MATERIAIS E MÉTODOS: Trinta e dois pacientes realizaram CPRM com aquisições 3D e 2D, com três estratégias de supressão do sinal líquido gastrintestinal: a apenas em jejum; b 12 horas após ingerir 300 mg de ranitidina; c após a ingestão de solução de gadolínio. Três observadores avaliaram os estudos, atentos para o grau de visualização da árvore biliopancreática. Foi medida a concordância interobservador com o teste kappa. A diferença entre técnicas e formas de aquisição foi avaliada pela média da soma dos escores de graduação. RESULTADOS: As três estratégias de supressão do sinal líquido gastrintestinal apresentaram elevada reprodutibilidade. A supressão do sinal líquido gastrintestinal com a ranitidina foi semelhante ao jejum e ambas foram piores do que a solução de gadolínio. As aquisições 3D superaram a 2D apenas na visualização do ducto cístico e da vesícula biliar, sendo inferior ou equivalente nos demais segmentos ductais biliopancreáticos. CONCLUSÃO: O uso da ranitidina não parece justificado para aprimorar a avaliação da árvore biliopancreática em exames de CPRM. A CPRM 2D apenas em jejum permite a visualização ductal com elevada qualidade e reprodutibilidade na maioria dos casos.OBJECTIVE: To assess the impact of oral ranitidine on the imaging quality in magnetic resonance cholangiopancreatography (MRCP.

    Objective: the present study is aimed at showing the different characteristics of pharyngoceles in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) and its correlation with clinical presentation. Material and method: pharyngocele cases were selected in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) realized in our service, realizing clinical presentation correlation. Results: pharyngocele presents frequently with small dimensions and narrow orifice. When the size enlarges, clinical presentation is more evident and diverse, which can confuse with other cervical lesions that enlarge with Valsalva maneuver. Differential diagnosis can be done by imaging evaluation. Conclusion: we intended to demonstrate that many times pharyngocele can be presented with different aspects, not always being easy to recognize by clinics or imaging exams, but its diagnosis must be always remembered in our daily practice.

  16. Optimal Weighting for Exam Composition

    Directory of Open Access Journals (Sweden)

    Sam Ganzfried

    2018-03-01

    Full Text Available A problem faced by many instructors is that of designing exams that accurately assess the abilities of the students. Typically, these exams are prepared several days in advance, and generic question scores are used based on rough approximation of the question difficulty and length. For example, for a recent class taught by the author, there were 30 multiple choice questions worth 3 points, 15 true/false with explanation questions worth 4 points, and 5 analytical exercises worth 10 points. We describe a novel framework where algorithms from machine learning are used to modify the exam question weights in order to optimize the exam scores, using the overall final score as a proxy for a student’s true ability. We show that significant error reduction can be obtained by our approach over standard weighting schemes, i.e., for the final and midterm exam, the mean absolute error for prediction decreases by 90.58% and 97.70% for linear regression approach respectively resulting in better estimation. We make several new observations regarding the properties of the “good” and “bad” exam questions that can have impact on the design of improved future evaluation methods.

    2014-05-01

    Full Text Available Introduction: The Ultrasound Screening Exam for Underlying Lesions (USEFUL was developed in an attempt to establish a role for bedside ultrasound in the primary and preventive care setting. It is the purpose of our pilot study to determine if students were first capable of performing all of the various scans required of our USEFUL while defining such an ultrasound-assisted physical exam that would supplement the standard hands-on physical exam in the same head-to-toe structure. We also aimed to assess the time needed for an adequate exam and analyze if times improved with repetition and previous ultrasound training. Methods: Medical students with ranging levels of ultrasound training received a 25-minute presentation on our USEFUL followed by a 30-minute hands-on session. Following the hands-on session, the students were asked to perform a timed USEFUL on 2-3 standardized subjects. All images were documented as normal or abnormal with the understanding that an official detailed exam would be performed if an abnormality were to be found. All images were read and deemed adequate by board eligible emergency medicine ultrasound fellows. Results: Twenty-six exams were performed by 9 students. The average time spent by all students per USEFUL was 11 minutes and 19 seconds. Students who had received the University of California, Irvine School of Medicine’s integrated ultrasound curriculum performed the USEFUL significantly faster (p< 0.0025. The time it took to complete the USEFUL ranged from 6 minutes and 32 seconds to 17 minutes, and improvement was seen with each USEFUL performed. The average time to complete the USEFUL on the first standardized patient was 13 minutes and 20 seconds, while 11 minutes and 2 seconds, and 9 minutes and 20 seconds were spent performing the exam on the second and third patient, respectively. Conclusion: Students were able to effectively complete all scans required by the USEFUL in a timely manner. Students who have

  3. Do Collaborative Exams Really Promote Learning?

    Science.gov (United States)

    Miller, Scott; James, C. Renee

    2018-01-01

    Collaborative, two-stage exams are becoming more popular in physics and astronomy courses, and their supposed benefits in terms of collaborative learning have been reported in the field of physics. In a collaborative, two-stage exam, students first complete an exam individually. Once that portion of the exam is over, students then retake all or part of the exam within a group, where they are able to discuss the questions with their peers and arrive at a common answer. While there are a number of papers that discuss the purported benefits of this method from a collaborative point of view, few, if any discuss the actual benefits in terms of student learning. One paper found that when students were presented with previous exam questions a few weeks later, they performed better on questions covered previously in the group portion of the exam compared to similar questions which were tested but not part of the group portion. But, when students were retested on exam questions which were administered earlier, roughly six to seven weeks beforehand, no difference was found in their performance on the two sets of questions.We present preliminary findings comparing student performance levels on multiple sets of exam questions administered to students in an introductory astronomy course where two-stage exams are administered. Questions were administered first in an exam during the course of the semester, then again during a final exam. During the semester exams, one set of questions was also contained within the group portion of the exam, while questions similar in concept and difficulty were not. A comparison of student performance on these two sets of questions are compared to evaluate the usefulness of collaborative exams to promote learning.

On the basis of a research with a Brazilian men's magazine, VIP Exame, which involved the analysis of issues of the magazine as well as an observation of the working process of the reporters and journalists, I focus my comments on the way the masculine body is treated by the magazine and how a discourse emerges on masculinity where attention to "good looks" becomes an important feature of a successful masculinity. On the basis of these observations I go on to discuss feminist and other theories of the subject, in order to understand how the reflexive monitoring of the body is increasingly important in the constitution of gender identities.

    This article aims to deconstruct various design qualities and strategies of clinic exam rooms, and discuss how they influence users' interaction and behavior in the space. Relevant literature supports the advantages and disadvantages of different design strategies. Annotated exam room prototypes illustrate the design qualities and strategies discussed. Advancements in technology and medicine, along with new legislative policies, are influencing the way care providers deliver care and ultimately clinic exam room designs. The patient-centered medical home model has encouraged primary care providers to make patients more active leaders of their health plan which will influence the overall functionality and configuration of clinic exam rooms. Specific design qualities discussed include overall size, location of doors and privacy curtains, positioning of exam tables, influence of technology in the consultation area, types of seating, and placement of sink and hand sanitizing dispensers. In addition, future trends of exam room prototypes are presented. There is a general lack of published evidence to support design professionals' design solutions for outpatient exam rooms. Future research should investigate such topics as the location of exam tables and privacy curtains as they relate to patient privacy; typical size and location of consultation table as it relates to patient connection and communication; and placement of sinks and sanitization dispensers as they relate to frequency and patterns of usage.

  10. Radiation exams in occupational medical evaluations

    International Nuclear Information System (INIS)

    Gelsleichter, A.M.; Hunh, A.; Nandi, D.M.

    2017-01-01

    Introduction: In occupational medicine, medical care must be geared toward the prevention of worker health. However, occupational medical exams often seek only through rigorous screening, reduce absenteeism, and thus increase productivity. To meet this goal, many institutions include radiological examinations indiscriminately in their medical and expert evaluations, contrary to the principle of justification. Objective: To provide a reflection about the presence of radiological exams in occupational medical evaluations. Methodology: Literary review including legislation related to the research topic. Results: Portaria 453/98 ANVISA prohibits the performance of radiological examinations for employment or expert purposes, except in cases where the exam may bring a benefit to the health of the individual examined or to society. However, in some situations the Norma Regulamentadora number 7 of the Ministry of Labor and Employment provides for radiological exams as a parameter for monitoring occupational exposure. Article 168 of the Consolidation of Labor Laws also prescribes that additional examinations may be required, at the medical discretion, to determine the physical and mental fitness of the employee for the job. Conclusion: Although there are legal provisions that prohibit and others that allow radiological exams in medical occupational evaluations, companies and institutions should take into account that any radiological exam has a risk involved and should not request them in a compulsory and indiscriminate manner. Radiological exams are only permissible to elucidate the diagnostic hypothesis produced by clinical evaluation, in order to provide a real benefit for the individual

    2013-05-01

    The authors of this commentary discuss the recently completed review of the current Medical College Admission Test (MCAT), which has been used since 1991, and describe the blueprint for the new test that will be introduced in 2015. The design of the MCAT exam reflects changes in medical education, medical science, health care delivery, and the needs of the populations served by graduates of U.S. and Canadian medical schools. The authors describe how balancing the ambitious goals for the new exam and the varying priorities of the testing program's many stakeholders made blueprint design complex. They discuss the tensions and trade-offs that characterized the design process as well as the deliberations and data that shaped the blueprint.The blueprint for the MCAT exam balances the assessment of a broad range of competencies in the natural, social, and behavioral sciences and critical analysis and reasoning skills that are essential to entering students' success in medical school. The exam will include four sections: Biological and Biochemical Foundations of Living Systems; Chemical and Physical Foundations of Biological Systems; Psychological, Social, and Biological Foundations of Behavior; and Critical Analysis and Reasoning Skills.The authors also offer recommendations for admission committees, advising them to review applicants' test scores, course work, and other academic, personal, and experiential credentials as part of a holistic admission process and in relation to their institutions' educational, scientific, clinical, and service-oriented goals.

    2009-04-01

    This study examined why some high achievers on the course final exam were unsuccessful on the proficiency exam in English. We hypothesized that the learning motives and learning behaviors (learning strategy, learning time) had different effects on the outcomes of the exams. First, the relation between the variables was investigated using structural equation modeling. Second, the learning behaviors of students who got good marks on both exams were compared with students who did well only on the course final exam. The results were as follows. (a) Learning motives influenced test performance via learning behaviors. (b) Content-attached motives influenced all variables concerning learning behaviors. (c) Content-detached motives influenced all variables concerning learning behaviors that were related only to the course final exam. (d) The students who got good marks on both exams performed the learning behaviors that were useful on the proficiency exam more frequently than the students who did well only on the course final exam.

    2018-07-01

    Diabetic retinopathy is a common microvascular complication of diabetes mellitus and is the leading cause of new blindness among working-age adults in the United States. Timely intervention to prevent vision loss is possible with early detection by regular eye examinations. Unfortunately, adherence to recommended annual diabetic eye exams is poor. Public health interventions have targeted traditional barriers to care, such as cost and transportation, with limited success. Behavioral economics provides an additional framework of concepts and tools to understand low screening rates and to promote regular diabetic eye exams for populations at risk. In particular, behavioral economics outlines biases and heuristics that affect decision-making and underlie pervasive barriers to care, such as not viewing diabetic eye exams as a priority or perceiving oneself as too healthy to need an examination. In this review, we examine the literature on the use of behavioral economics interventions to promote regular diabetic eye exams. From the results of the included studies, we outline how concepts from behavioral economics can improve eye examination rates. In particular, the default bias, present bias, and self-serving bias play a significant role in precluding regular diabetic eye examinations. Potential tools to mitigate these biases include leveraging default options, using reminder messages, providing behavioral coaching, applying commitment contracts, offering financial incentives, and personalizing health messages. When combined with traditional public health campaigns, insights from behavioral economics can improve understanding of pervasive barriers to care and offer additional strategies to promote regular preventive eye care for patients with diabetes.

    Full Text Available Introdução: O estudo da rinoplastia representa grande dificuldade para a formação do cirurgião plástico, devido à complexidade técnica encontrada associada ao reduzido campo operatório. Alguns modelos experimentais, como o nariz do coelho, ovelha, cartilagem esternal do frango e também modelos tridimensionais do nariz humano já foram descritos. O objetivo do presente trabalho é relatar a experiência do serviço de cirurgia plástica na utilização da cartilagem esternal do frango como modelo experimental para o treinamento da rinoplastia. Método: Foi realizada documentação da utilização da cartilagem esternal do frango para o treinamento de técnicas empregadas na rinoplastia. Um peito de frango sem a pele foi preparado a partir da fervura em água por 20 minutos, com a finalidade de facilitar a separação do componente osteocartilaginoso necessário ao treinamento, sem comprometer a cartilagem. Resultados: A partir do material obtido, foi possível realizar a dissecção e manipulação estrutural da cartilagem. A facilidade em manipular as estruturas permitiu a confecção dos principais enxertos utilizados, como a simulação da retirada de enxerto de cartilagem septal, spreader graft, strut graft, enxerto de alar e enxerto de Sheen. Conclusões: O emprego da cartilagem esternal do frango para o treinamento da rinoplastia é de grande utilidade, visto que a habilidade técnica para a confecção de enxertos cartilaginosos exige experiência clínica e demorada curva de aprendizado. Este modelo oferece tecidos muito semelhantes ao material humano e pode ser obtido com facilidade e baixo custo.

    Full Text Available In this clinical study on helping students prepare for an exam, we compared three different treatments. All students were asked to take a practice exam. One group was then given worked-out solutions for that exam, another group was given the solutions and targeted exercises to do as homework based on the result of their practice exam, and the third group was given the solutions, homework, and also an hour of one-on-one tutoring. Participants from all three conditions significantly outperformed the control group on the midterm exam. However, participants that had one-on-one tutoring did not outperform the other two participant groups.

    Full Text Available As lavanderias e tinturarias industriais geram efluentes líquidos que, após tratamento por decantação da matéria em suspensão, produzem lodo. Esse resíduo tem composição química variada em virtude dos produtos usados no processo. Tal resíduo é considerado inadequado para a disposição, in natura, no meio ambiente, devendo ter como destinação final um aterro industrial. No caso em exame, não se dispõe desse tipo de aterro, e os resíduos são transportados por via rodoviária até cerca de 400km de distância, causando um forte impacto financeiro na produção de um emergente mercado local de indústria têxtil e de confecção. Este trabalho apresenta a caracterização físico-química do lodo proveniente de uma lavanderia industrial, para o estudo de sua disposição final, em processo de E/S, em pasta de cimento e em argamassa de cimento e areia normal. A adição de cimento portland - CPI 32 ou CP II Z - visa ao seu reaproveitamento em materiais de construção civil e objetiva minimizar os custos de disposição final deste resíduo. Nesta caracterização, analisaram-se: sedimentação, DQO, sólidos totais, fixos e voláteis no lodo, densidade, pH, e a presença de metais, sendo detectada a presença dos metais Fe, Mg, Al, Sn, Ca, Cr, Co, Cu, Mn e Zn. Corpos de prova de pasta e argamassa foram submetidos à análise de resistência à compressão e também testes de lixiviação na argamassa. Os resultados demonstraram que na pasta de cimento e lodo os valores de resistência mecânica, aos 28 dias, atingem valores maiores que 10 MPa. E, as argamassas com adição de teores de lodo menores que 25% em relação à massa de cimento, possuem valores de resistência mecânica maiores que 10 Mpa, aos 28 dias, o que permite sua utilização como material de construção civil secundário, sem função estrutural. Também de maneira geral, a lixiviação ocorrida nos corpos de prova de argamassa sem lodo incorporado foi da mesma

    In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid

    Coletta, Vincent; Wikholm, Colin; Pascoe, Daniel

    2018-03-01

    Most physics instructors believe that adequate sleep is important in order for students to perform well on problem solving, and many instructors advise students to get plenty of sleep the night before an exam. After years of giving such advice to students at Loyola Marymount University (LMU), one of us decided to find out how many hours students actually do sleep the night before an exam, and how that would relate to their performance. The effect of inadequate sleep on exam performance was explored in a second-semester introductory physics course. At the end of the final exam, students reported the number of hours they slept the night before. Sleep deprivation corresponded to lower final exam scores. The main purpose of this study is to provide evidence that instructors can provide to their students to convince them that their time is better spent sleeping rather than studying all night before an exam.

    Full Text Available Justificativa e objetivos: a solicitação indiscriminada de exames complementares na avaliação pré-anestésica é comum na prática clínica e implica custos adicionais e a possibilidade de resultados falso-positivos. Os objetivos desta pesquisa foram analisar se os exames pré-operatórios em cirurgias eletivas são solicitados segundo critério clínico e avaliar os custos desnecessários para a instituição. Métodos: foram avaliadas as solicitações de exames pré-operatórios em pacientes adultos submetidos a cirurgias eletivas não cardíacas. Os exames foram solicitados pelos cirurgiões, conforme protocolo do Serviço de Anestesia. Foram avaliados dados demográficos, estado físico, comorbidades e tipo de exame complementar solicitado. Os exames feitos foram comparados com os exames indicados. O custo dos exames foi baseado na tabela Datasus. Resultados: foram avaliados 1.063 pacientes. Verificou-se que 41,9% dos exames feitos nos pacientes classificados como ASA I não estavam indicados. No grupo de risco ASA II foram feitos 442 exames (17,72% sem necessidade. Perceberam-se elevadas porcentagens na solicitação de hemograma, creatinina, coagulograma, raios X de tórax e ECG nos grupos ASA I-II. Apenas 40 (5,25% dos exames feitos no grupo ASA III não estavam indicados. Nos pacientes do grupo ASA IV, 22,5% dos exames necessários não foram feitos. Ressalta-se uma economia anual de 13% (R$1.923,13 caso os exames fossem feitos conforme o protocolo. Conclusões: os exames pré-operatórios nem sempre são solicitados de acordo com critérios clínicos, o que resulta em maiores custos para a instituição.

    2018-03-01

    Full Text Available The weighting of a final exam or a final assignment is an essential part of course design that is rarely discussed in pedagogical literature. Depending on the weighting, a final exam or assignment may provide unequal benefits to students depending on their prior performance in the class. Consequently, uncritical grade weighting can discount student learning, by ensuring that improved mastery of material at the semester’s end is not reflected in the course grade. Problems related to several common final exam weights are explored, as are potential solutions to unequal student outcomes made possible by uncritical grade weighting. Ultimately, this essay argues that choosing a weight for a final exam or a final assignment determines what types of student success ought to be possible in the class; therefore, instructors should assign exam weights intentionally, being fully aware of the potential benefits and problems of the weights that they choose.

    Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved groups. In this study, we examined whether and to what extent the characteristics of instructor-generated tests impact the exam performance of male and female and middle/high- and low-socioeconomic status (SES) students enrolled in introductory biology courses. We collected exam scores for 4810 students from 87 unique exams taken across 3 yr of the introductory biology series at a large research university. We determined the median Bloom’s level and the percentage of constructed-response questions for each exam. Despite controlling for prior academic ability in our models, we found that males and middle/high-SES students were disproportionately favored as the Bloom’s level of exams increased. Additionally, middle/high-SES students were favored as the proportion of constructed-response questions on exams increased. Given that we controlled for prior academic ability, our findings do not likely reflect differences in academic ability level. We discuss possible explanations for our findings and how they might impact how we assess our students. PMID:27252299

    2015-01-01

    Aseptic technique includes the use of sterile surgical gloves for survival surgeries in rodents to minimize the incidence of infections. Exam gloves are much less expensive than are surgical gloves and may represent a cost-effective, readily available option for use in rodent surgery. This study examined the effectiveness of surface disinfection of exam gloves with 70% isopropyl alcohol or a solution of hydrogen peroxide and peracetic acid (HP–PA) in reducing bacterial contamination. Performance levels for asepsis were met when gloves were negative for bacterial contamination after surface disinfection and sham ‘exertion’ activity. According to these criteria, 94% of HP–PA-disinfected gloves passed, compared with 47% of alcohol-disinfected gloves. In addition, the effect of autoclaving on the integrity of exam gloves was examined, given that autoclaving is another readily available option for aseptic preparation. Performance criteria for glove integrity after autoclaving consisted of: the ability to don the gloves followed by successful simulation of wound closure and completion of stretch tests without tearing or observable defects. Using this criteria, 98% of autoclaved nitrile exam gloves and 76% of autoclaved latex exam gloves met performance expectations compared with the performance of standard surgical gloves (88% nitrile, 100% latex). The results of this study support the use of HP–PA-disinfected latex and nitrile exam gloves or autoclaved nitrile exam gloves as viable cost-effective alternatives to sterile surgical gloves for rodent surgeries.

  6. Evaluating multiple-choice exams in large introductory physics courses

    Directory of Open Access Journals (Sweden)

    Gary Gladding

    2006-07-01

    Full Text Available The reliability and validity of professionally written multiple-choice exams have been extensively studied for exams such as the SAT, graduate record examination, and the force concept inventory. Much of the success of these multiple-choice exams is attributed to the careful construction of each question, as well as each response. In this study, the reliability and validity of scores from multiple-choice exams written for and administered in the large introductory physics courses at the University of Illinois, Urbana-Champaign were investigated. The reliability of exam scores over the course of a semester results in approximately a 3% uncertainty in students’ total semester exam score. This semester test score uncertainty yields an uncertainty in the students’ assigned letter grade that is less than 1 / 3 of a letter grade. To study the validity of exam scores, a subset of students were ranked independently based on their multiple-choice score, graded explanations, and student interviews. The ranking of these students based on their multiple-choice score was found to be consistent with the ranking assigned by physics instructors based on the students’ written explanations ( r>0.94 at the 95% confidence level and oral interviews (r=0.94−0.09+0.06 .

  7. FLEX: A Modular Software Architecture for Flight License Exam

    Arsan, Taner; Saka, Hamit Emre; Sahin, Ceyhun

    This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. The implemented system has basic specifications such as appending questions in system, building exams with these appended questions and making students to take these exams. There are three different types of users with different authorizations. These are system administrator, operators and students. System administrator operates and maintains the system, and also audits the system integrity. The system administrator can not be able to change the result of exams and can not take an exam. Operator module includes instructors. Operators have some privileges such as preparing exams, entering questions, changing the existing questions and etc. Students can log on the system and can be accessed to exams by a certain URL. The other characteristic of our system is that operators and system administrator are not able to delete questions due to the security problems. Exam questions can be inserted on their topics and lectures in the database. Thus; operators and system administrator can easily choose questions. When all these are taken into consideration, FLEX software provides opportunities to many students to take exams at the same time in safe, reliable and user friendly conditions. It is also reliable examination system for the authorized aviation administration companies. Web development platform - LAMP; Linux, Apache web server, MySQL, Object-oriented scripting Language - PHP are used for developing the system and page structures are developed by Content Management System - CMS.

    To evaluate predictive validity of cognitive dysfunction of the Saint Louis University mental status (SLUMS) exam or mini-mental state exam (MMSE) for institutionalization and mortality after 7.5-years. Longitudinal study. Geriatric Research, Education and Clinical Center Veterans Affairs Hospital St. Louis, MO. Patients (N=705) were screened for cognitive dysfunction in 2003 using the SLUMS exam and MMSE, and mortality and institutionalization up to 7.5-years later were evaluated as outcome measures. The associations between outcome measures and MMSE and SLUMS exam total scores, and cognitive status were examined using Kaplan-Meier curves and Cox proportional-hazards regression. Five hundred thirty-three charts were reviewed, 176/533(33%) patients had died and 31/526 (6%) were institutionalized during 7.5-year follow-up period. All subjects were male with a mean age of 75 years and most had high school education or greater (71%). MMSE dementia, SLUMS dementia (ps<.001) and MCI (p<.05) groups had significantly lower survival rates than normal cognition group in the Kaplan-Meier curves. Scores classified as dementia on SLUMS (HR=2.4, 95% CI 1.6-3.7; p <.001) or MMSE (HR=2.3, 95% CI 1.5-3.6; p <.001) both predicted mortality and, also, institutionalization (SLUMS: HR=3.5, 95% CI 1.3-9.1; p <.01; MMSE: HR=3.8, 95% CI 1.6-9.0; p <.001) after adjustment for covariates. Unadjusted SLUMS exam MCI predicted morality (HR=1.5, 95% CI 1.1-2.2; p <.019) but not institutionalization. The SLUMS exam and MMSE both predict mortality and institutionalization for male patients screened as positive for dementia.

    2014-11-02

    To examine the relationship between study strategies and performance on a high stakes medical licensing exam entitled the United States Medical Licensing Examination Step 1. The action research project included seventy nine student participants at the Texas A & M Health Science Center College of Medicine during their pre-clinical education. Data collection included pre-matriculation and matriculation academic performance data, standardized exam data, and the Learning and Study Strategies Instrument. Multiple regression analyses were conducted. For both models, the dependent variable was the Step 1 score, and the independent variables included Medical College Admission Test, Undergraduate Grade Point Average, Year 1 Average, Year 2 Average, Customized National Board of Medical Examiners Average, Comprehensive Basic Science Exam score, and Learning and Study Strategy Instrument sub-scores. Model 2 added Comprehensive Basic Science Self-Assessment average. Concentration (Model 1 - β = .264; Model 2 - β = .254) was the only study strategy correlated with Step 1 performance. The other statistically significant predictors were Customized National Board of Medical Examiners Average (β = .315) and Year 2 Average (β = .280) in Model 1 and Comprehensive Basic Science Self-Assessment Average (β = .338) in Model 2. There does appear to be a relationship between the study strategy concentration and Step 1 licensing exam performance. Teaching students to practice and utilize certain techniques to improve concentration skills when preparing for and taking exams may help improve licensing exam scores.

  14. Does Question Structure Affect Exam Performance in the Geosciences?

    2015-12-01

    The jump to university level exams can be challenging for some students, often resulting in poor marks, which may be detrimental to their confidence and ultimately affect their overall degree class. Previous studies have found that question structure can have a strong impact on the performance of students in college level exams (see Gibson et al., 2015, for a discussion of its impact on physics undergraduates). Here, we investigate the effect of question structure on the exam results of geology and geophysics undergraduate students. Specifically, we analyse the performance of students in questions that have a 'scaffolded' framework and compare them to their performance in open-ended questions and coursework. We also investigate if observed differences in exam performance are correlated with the educational background and gender of students, amongst other factors. It is important for all students to be able to access their degree courses, no matter what their backgrounds may be. Broadening participation in the geosciences relies on removing systematic barriers to achievement. Therefore we recommend that exams are either structured with scaffolding in questions at lower levels, or students are explicitly prepared for this transition. We also recommend that longitudinal studies of exam performance are conducted within individual departments, and this work outlines one approach to analysing performance data.

    Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved groups. In this study, we examined whether and to what extent the characteristics of instructor-generated tests impact the exam performance of male and female and middle/high- and low-socioeconomic status (SES) students enrolled in introductory biology courses. We collected exam scores for 4810 students from 87 unique exams taken across 3 yr of the introductory biology series at a large research university. We determined the median Bloom's level and the percentage of constructed-response questions for each exam. Despite controlling for prior academic ability in our models, we found that males and middle/high-SES students were disproportionately favored as the Bloom's level of exams increased. Additionally, middle/high-SES students were favored as the proportion of constructed-response questions on exams increased. Given that we controlled for prior academic ability, our findings do not likely reflect differences in academic ability level. We discuss possible explanations for our findings and how they might impact how we assess our students. © 2016 C. D. Wright, S. L. Eddy, et al.

  19. Diagnosis of Alzheimer's disease in Brazil: Supplementary exams

    Directory of Open Access Journals (Sweden)

    Paulo Caramelli

    Full Text Available Abstract This article presents a review of the recommendations on supplementary exams employed for the clinical diagnosis of Alzheimer's disease (AD in Brazil published in 2005. A systematic assessment of the consensus reached in other countries, and of articles on AD diagnosis in Brazil available on the PUBMED and LILACS medical databases, was carried out. Recommended laboratory exams included complete blood count, serum creatinine, thyroid stimulating hormone (TSH, albumin, hepatic enzymes, Vitamin B12, folic acid, calcium, serological reactions for syphilis and serology for HIV in patients aged younger than 60 years with atypical clinical signs or suggestive symptoms. Structural neuroimaging, computed tomography or - preferably - magnetic resonance exams, are indicated for diagnostic investigation of dementia syndrome to rule out secondary etiologies. Functional neuroimaging exams (SPECT and PET, when available, increase diagnostic reliability and assist in the differential diagnosis of other types of dementia. The cerebrospinal fluid exam is indicated in cases of pre-senile onset dementia with atypical clinical presentation or course, for communicant hydrocephaly, and suspected inflammatory, infectious or prion disease of the central nervous system. Routine electroencephalograms aid the differential diagnosis of dementia syndrome with other conditions which impair cognitive functioning. Genotyping of apolipoprotein E or other susceptibility polymorphisms is not recommended for diagnostic purposes or for assessing the risk of developing the disease. Biomarkers related to the molecular alterations in AD are largely limited to use exclusively in research protocols, but when available can contribute to improving the accuracy of diagnosis of the disease.

  20. Developing a prelicensure exam for Canada: an international collaboration.

    Hobbins, Bonnie; Bradley, Pat

    2013-01-01

    Nine previously conducted studies indicate that Elsevier's HESI Exit Exam (E(2)) is 96.36%-99.16% accurate in predicting success on the National Council Licensure Examination for Registered Nurses. No similar standardized exam is available in Canada to predict Canadian Registered Nurse Examination (CRNE) success. Like the E(2), such an exam could be used to evaluate Canadian nursing students' preparedness for the CRNE, and scores on the numerous subject matter categories could be used to guide students' remediation efforts so that, ultimately, they are successful on their first attempt at taking the CRNE. The international collaboration between a HESI test construction expert and a nursing faculty member from Canada, who served as the content expert, resulted in the development of a 180-item, multiple-choice/single-answer prelicensure exam (PLE) that was pilot tested with Canadian nursing students (N = 175). Item analysis data obtained from this pilot testing were used to develop a 160-item PLE, which includes an additional 20 pilot test items. The estimated reliability of this exam is 0.91, and it exhibits congruent validity with the CRNE because the PLE test blueprint mimics the CRNE test blueprint. Copyright © 2013 Elsevier Inc.

    2013-01-01

    Due to the use of radiopharmaceutical positron-emitting in PET exam and realization of tomography by x-ray transmission in CT examination, an increase of dose with hybrid PET/CT technology is expected. However, differences of doses have been reported in many countries for the same type of procedure. It is expected that the dose is an influent parameter to standardize the protocols of PET/CT. This study aimed to estimate the effective doses and absorbed in 65 patients submitted to oncological Protocol in a nuclear medicine clinic in Rio de Janeiro, considering the risk of induction of cancer from the scan. The CT exam-related doses were estimated with a simulator of PMMA and simulated on the lmPACT resistance, which for program effective dose, were considered the weight factors of the lCRP 103. The PET exam doses were estimated by multiplying the activity administered to the patient with the ICRP dose 80 factors. The radiological risk for cancer incidence were estimated according to the ICRP 103. The results showed that the effective dose from CT exam is responsible for 70% of the effective total in a PET/CT scan. values of effective dose for the PET/CT exam reached average values of up to 25 mSv leading to a risk of 2, 57 x 10 -4 . Considering that in staging of oncological diseases at least four tests are performed annually, the total risk comes to 1,03x 10 -3

    Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient

    e-Learning has become increasingly important in chemical education and online exams can be an attractive alternative to traditional exams written on paper, particularly in classes with a large number of students. Ten years ago, we began to set up an e-course complementing our lecture courses Organic Chemistry I and II within the open-source e-learning environment Moodle. In this article, we retrace a number of decisions we took over time, thereby illustrating the challenges one faces when creating online exercises and exams in (organic) chemistry. Special emphasis is put on the development of MOSFECCS (MOlecular Structural Formula Editor and Calculator of Canonical SMILES), our new editor for drawing structural formulae and converting them to alphanumeric SMILES codes that can be submitted as answers to e-problems. Convinced that the possibility for structure input is essential to set up sensible chemistry quizzes and exams, and realising that existing tools present major flaws in an educational context, we decided to embark on the implementation of MOSFECCS which takes into account a number of didactic aspects.

    The increasing use of imaging technologies and the installation of more sophisticated equipment in radiology services, such as multi-slice CT scanners have consequently increased the number of treated patients, as well as the collective doses to population. Radiation doses received from CT exams are higher than those received in conventional radiology. The optimal use of CT equipment, considering optimized techniques, and the justification of examinations, are imperative in order to minimize the undesirable effects of radiation. In this paper we do set out to the assessment of justification criteria applied for CT exams in a Cuban Hospital. The justification of prescribed tests by physicians was analyzed, assessing its incidence depending on the kind of studies and percentage (%) of positive and negative cases. The study was carried out in a Clinical Surgical Hospital in Havana City. This hospital has installed a Shimadzu SCT-7800TC helical single-slice device. The sample is made up of 81 patients, between 24 and 80 years old, both men and women. For all of them the pathology that causes the order of the exam as well as the existence of other previous tests, were considered. As a result of the assessment, the 56.8% of all cases turned out to be positives; the 55.5% only confirmed the pathologies and the 1.23% produced new evidences. On the other hand, the remaining 43.2% were negatives noting that the 65.3% of the patients there were not previous imaging tests. Skull exam was the most incidences compiling the 67.7% of cases, and it was the headache the most frequent clinical problem to perform the 41.1%. In terms of justification, the evaluation of prescriptions evidenced that CT exams were not justified in 43.2% of cases. As part of this last group, it was also found that 46.9% of clinical studies were negative. (author)

  7. Investigating the effects of exam length on performance and cognitive fatigue.

    Directory of Open Access Journals (Sweden)

    Jamie L Jensen

    Full Text Available This study examined the effects of exam length on student performance and cognitive fatigue in an undergraduate biology classroom. Exams tested higher order thinking skills. To test our hypothesis, we administered standard- and extended-length high-level exams to two populations of non-majors biology students. We gathered exam performance data between conditions as well as performance on the first and second half of exams within conditions. We showed that lengthier exams led to better performance on assessment items shared between conditions, possibly lending support to the spreading activation theory. It also led to greater performance on the final exam, lending support to the testing effect in creative problem solving. Lengthier exams did not result in lower performance due to fatiguing conditions, although students perceived subjective fatigue. Implications of these findings are discussed with respect to assessment practices.

    Full Text Available We have examined whether cadaver dissection by first year medical students (MIs affected their performance in two test measures: the NBME Gross Anatomy and Embryology Subject Exam (dissection-relevant questions only, and practical exams given at the end of each major section within the course. The dissections for the entire course were divided into 18 regional dissection units and each student was assigned to dissect one third of the regional units; the other two-thirds of the material was learned from the partner-prosected cadavers. Performance for each student on the exams was then assessed as a function of the regions those students actually dissected. While the results indicated a small performance advantage for MIs answering questions on material they had dissected on the NBME Subject Exam questions relevant to dissection (78-88% of total exam, the results were not statistically significant. However, a similar, small performance advantage on the course practical exams was highly significant.

    Developmental hip disorder (DHD) is a disorder in development of the acetabulum which remains abrupt (dysplasia) and probably consequential cranialisation of the femur head (luxation). The aim of this paper is to establish the total number of DHD and its subtypes at the first clinical and ultrasound exam of newborns in a retrospective-prospective study made in the period from 1st Jan 2006 through to 31 Dec 2010 at the Clinic for orthopaedics and traumatology in Banja Luka. In total 6132 patients were examined and 99 cases diagnosed with DHD (dysplasia and luxation). Ultrasonic exam was done by means of electronic probe of 5-12 MHz according to standard method after Graph. Girls were significantly more present (96%). Positive family anamnesis on DHD was present with 7.8% examinee, mainly with primiparas, and/ or with 77.8% children with DHD. Dominant intrauterine risk factors for DHD were: mal position of foetus in uterus (78.6%), oligoamnion (17.9%), malformation of the spinal column of the pregnant woman (3.6%), whereas with 38.4% of children with a certain form of DHD the following were found: breech presentation, caesarean section or twin pregnancy. The clinical exam indicated DHD with 8.87% examinee, out of which hip looseness was found with 5% examinees. Ultrasonic finding was positive with 99 examinee, that is with 1.61% of them (deficient and badly formed acetabulum, sleeked protrusion; 8 luxations and 91 dysplasia). Prophylactic measures were requested by 58.6% children (abductive bending and exercises), whereas 41.4 % needed non-intervention therapeutic measures (traction, Pavlik's straps, Graph's knickers, plastering), after which there were no children needing surgical correction of DHD. These data indicate that clinical exam is unreliable for DHD diagnostics, and that Ultrasonic diagnostics and treatment of DHD should start as early as possible applying atraumatic helping devices and procedures in the period when all structures are elastic, flexible and

    In the current digital and filmless age of radiology, rates of unread radiology exams remain low, however, may still exist in unique environments. Veterans Affairs (VA) health care systems may experience higher rates of unread exams due to coexistence of Veterans Health Information Systems and Technology Architecture (VistA) imaging and commercial picture archiving and communication systems (PACS). The purpose of this patient safety initiative was to identify any unread exams and causes leading to unread exams. Following approval by departmental quality assurance committee, a comprehensive review was performed of all radiology exams within VistA imaging from July 1, 2009 to June 30, 2014 to identify unread radiology exams. Over the 5-year period, the total unread exam rate was calculated to be 0.17%, with the highest yearly unread exam rate of 0.25%. The leading majority of unread exam type was plain radiographs. Analysis revealed unfinished dictations, unassociated accession numbers, technologist errors, and inefficient radiologist work lists as top contributors to unread exams. Once unread radiology exams were discovered and the causes identified, valuable process changes were implemented within our department to ensure simultaneous tracking of all unread exams in VistA imaging as well as the commercial PACS.

    Background: preoperative exams aim to identify disorders that may compromise the patient´s perioperative care. However, unnecessary tests rarely change the outcome, and are expensive to institution. The aim of this study was to evaluate the preoperative tests ordered in Santa Lucinda hospital, Sorocaba - SP. Methods: after approval by the Ethics Committee of PUC-SP University, we assessed pre-anesthetic evaluation of patients undergoing elective surgery from march to August, 2011. We recorded: age, sex, ASA physical status, the presence of coexisting diseases, medication use, type of surgery and preoperative tests. They were classified as sufficient, sufficient with unnecessary tests, insufficient, or insufficient with unnecessary tests. Results: two hundred and nineteen records were evaluated, of which 52% were considered sufficient, but with unnecessary tests. For 24% of patients, the tests were insufficient, with some ordered unnecessarily. To 8% of patients, the tests were insufficient, and only 16% didn´t have insufficient and unnecessary tests. The most frequently ordered tests were hematocrit and hemoglobin. The exams most unnecessarily ordered were coagulation tests and dosage of serum urea. Among the necessary examinations, but unsolicited, there were ECG (27%, electrolytes (13% and creatinine (11%. Seventy-nine tests showed some kind of problem, but they didn´t change in behavior. Conclusions: preoperative tests unnecessarily ordered are frequent, which do not guarantee that some patients present to surgery without fundamental exams according to their risk group.

O critério diagnóstico atual para o DM propõe os seguintes testes laboratoriais: glicose plasmática em jejum, hemoglobina glicada ou glicosilada, teste oral de tolerância à glicose, frutosamina, insulina, peptídeo C e glucagon. Estes exames laboratoriais podem apresentar interferências de medicamentos, sejam fisiológicas ou analíticas. Na literatura consultada foi possível identificar 30 fármacos ou grupo de fármacos que possuem evidências de interferir nos principais exames de diagnóstico da DM. Ressalta-se que praticamente na sua totalidade estes interferem nos níveis de glicemia, sendo que, 81,5% destes contribuem de forma a aumentar estes valores. Dentre estes fármacos encontram-se MIPs (medicamentos isentos de prescrição, como o paracetamol e o ácido acetilsalicílico, e anti-inflamatórios esteroidais, como a dexametasona e prednisolona, amplamente utilizados na terapêutica medicamentosa. Da mesma forma, os medicamentos empregados no tratamento de pacientes diabéticos incluído na RENAME como insulina NPH (protamina neutra Hagedorn, insulina humana regular, glibenclamida, gliclazida e cloridrato de metformina podem interferir em exames laboratoriais. O diagnóstico precoce e o tratamento adequado se fazem necessários a fim de prevenirem maiores danos aos portadores desta doença complexa sub diagnosticada. Neste contexto, as interferências medicamentosas são importantes achados nos exames laboratoriais que avaliam o DM e devem ser reconhecidas pelos profissionais de saúde envolvidos.

The authors examine three questions regarding the FMEC recommendations and the revised MCAT exam: (1) Is the MCAT exam equal and useful in Canadian admissions? (2) Does the MCAT exam affect matriculant diversity? and (3) Is the MCAT exam a strong predictor of future performance? They present the most recent arguments and evidence for and against use of the MCAT exam, with the purpose of summarizing these different perspectives for readers.

    Awareness of imaging utilization increased after implementation of Radiology Order Entry with decision support systems (ROE-DS). Our hypothesis is few exams with low Clinical Appropriateness Score (CAS) on ROE-DS are performed. Clinical indications of exams with CAS less than 3 (9-point scale) were re-reviewed and reports analyzed. Structured Query Language-based query retrieved exams with CAS less than 3 in ROE-DS from January 2007 to December 2011. Reasons provided by physicians for ordering these exams and reports of exams performed were analyzed. For each indication, number of exams ordered and performed was calculated. Statistical significance was assessed using Student's t test and χ 2 analysis (P < .05). From 445,984 exams, 12,615 exams (2.8%) had CAS less than 3, and 7,956 exams (63%) were performed. Reasons for ordering of 12,615 low CAS exams were as follows: Requests by physician specialists without further explanation (4,516 = 35.8%), notation of special clinical circumstances (2,877 = 22.8%), requests by nonphysician staff without further explanation (1,383 = 10.9%), absence of suspected finding on previous modality (1,099 = 8.7%), patient preference (737 = 5.8%), and requests based on radiologists' recommendations (706 = 5.6%). Difference between male and female (male < female) preferences for low CAS exams was statistically significant (P < .01). Imaging outcome was highest for extremity MRI cases (66.7%; P < .01). Less than 3% of exams ordered had low CAS and about two-thirds of these were performed. Most common indication for ordering these exams was physician specialist request based on opinion of medical necessity without specification. Extremity MRI constituted the highest positive findings for low CAS exams performed. Published by Elsevier Inc.

    2015-12-01

    Blood pressure (BP) elevation in medical office settings in patients who are normotensive in nonmedical settings is an effect known as 'white coat hypertension'. This phenomenon is thought to be due to situational anxiety caused by the experience of visiting a doctor and the anxiety-inducing nature of the medical office. Our study was designed to determine if carefully selected photographic art could counter the anxiety that causes white coat hypertension and lead to lower BP recordings in some patients. 117 adults, non-pregnant patients from the Louisiana State University Health Sciences Center Family Medicine Resident Clinic participated in this study. After the triage nurse measured the BP, the patients were randomly placed in either an exam room with standard medical posters (control room) or in an exam room with photographic art (photo room). The BP was measured in the exam room. After the medical visit, the patients switched rooms and the BP was measured a third time. The patients were asked to fill out a questionnaire to identify room preference. On average, the BP obtained in the control rooms was higher than that obtained in the photo rooms. There was a statistically significant difference between the mean arterial pressure, systolic BP and diastolic BP between the control room and the photo room. Landscape photographic art may have the beneficial effect of reducing BP in medical office examination rooms. Published by the BMJ Publishing Group Limited.

    Full Text Available O artigo tenta demonstrar que todos os textos, mesmo aqueles cuja natureza é teórica, têm alguma forma de narrativa. Nem sempre são personagens que os ocupam, podem ser ideias, mas mesmo assim há um enredo conceitual que se passa. Modernamente, a forma dessa narrativa foi sobretudo o sistema, com a pretensão totalizadora presente, por exemplo, na filosofia de Hegel. Contemporaneamente, porém, a forma do ensaio – surgida ainda na era moderna – ganha destaque por sua forma descontínua de narrar. O objetivo do artigo é apontar que, se o ensaio é uma forma, como explicitaram Lukács, Benjamin e Adorno, ele é também uma forma de narrar – ainda que de narrar conceitualmente objetos da cultura.

    2014-10-01

    We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students' dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students' grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p=.01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R=0.1, p=.01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain. Copyright © 2014 Elsevier Inc.

    The purpose of this research was to understand the different ways that students in a second-semester general chemistry course studied for an exam. I conducted this research using a qualitative methodology based on phenomenography (Marton, Hounsell & Entwistle, 1997). I conducted interviews before and after the first exam in CHM 116. I analyzed these interviews to describe students' studying styles. I analyzed the data from four students and presented this data as case studies. I completed a cross-case analysis that included data from five additional students. My results describe three different studying styles that were found: visual, self-regulated, and quantitative. Each studying style included a description of the characteristics associated with students who use the style, including epistemological beliefs, specific study behaviors, and affective response to learning chemistry. My implications discuss the relationship between this study and learning styles research, as well as other phenomenographic research. Suggestions are made for how to adapt teaching methods to take into account the different studying styles.

    2015-01-01

    The present study examined why people differ in how they appraise the same stressful situation (an approaching exam). We explored whether interpreting anxiety as a facilitative emotion can affect the type of stress appraisal people make. One hundred and three undergraduate students took part in this study, which lasted for 10 days (leading up to an exam). The students completed a daily self-reported evaluation of anxiety, emotional exhaustion, and stress experienced. The findings suggest a process by which a stressful time can be experienced as motivating rather than threatening or emotionally exhausting. For example, interpreting anxiety as facilitative moderated the relationship between anxiety and stress appraisals. When interpreting their anxiety as facilitative, individuals showed a higher tendency to make challenge stress appraisals and a lower tendency to appraising the stressor as a threat. These differences were especially visible with high levels of anxiety. Furthermore, interpreting anxiety as facilitative was negatively associated with emotional exhaustion, but positively associated with the academic performance. These findings suggest an explanation why people differ in how they appraise the same stressor: how people interpret their anxiety may to a large part affect how they appraise difficult events and situations.

We aimed to objectively determine the impact of Tablet PC enhanced training on learning experience and MKSAP® (medical knowledge self-assessment program) exam performance. In this single center, prospective, controlled study final year medical students and medical residents doing an inpatient service rotation were alternatingly assigned to either the active test (Tablet PC with custom multimedia education software package) or traditional education (control) group, respectively. All completed an extensive questionnaire to collect their socio-demographic data, evaluate educational status, computer affinity and skills, problem solving, eLearning knowledge and self-rated medical knowledge. Both groups were MKSAP® tested at the beginning and the end of their rotation. The MKSAP® score at the final exam was the primary endpoint. Data of 55 (tablet n = 24, controls n = 31) male 36.4%, median age 28 years, 65.5% students, were evaluable. The mean MKSAP® score improved in the tablet PC (score Δ + 8 SD: 11), but not the control group (score Δ- 7, SD: 11), respectively. After adjustment for baseline score and confounders the Tablet PC group showed on average 11% better MKSAP® test results compared to the control group (plearning to their respective training programs.

    The objective of this paper is to estimate the values of doses, which are absorbed dose to the lens and thyroid in a dental X-ray. Thermoluminescence dosimeters were used, once they provide a reading of quality and effectiveness. This study was based on dental exams conducted in patients in order to estimate the dose that disperses to the lens of the eye and for the thyroid during an intraoral exam. Data collection took place in two institutions, one governmental, which had the device SELETRONIC 70X and other particular. This study showed that there is a considerable variation between the appliances. Using the appliance DABI 1070, there was a greater absorption of radiation in the right eye (values greater than 5 mGy) and a lower dose in the thyroid, and the Seletronic 70X presented an incidence of higher dose deposited in the skin and in other points there was a balance in the values. In the appliance SELETRONIC 70X, there was again a greater absorption of radiation in the right eye and a lower setting in the thyroid. The excessive dose, besides does not favor at all for the quality of radiograph, represents a risk for the patient who absorbs unnecessary and harmful radiation to the body

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

Com o objetivo de traçar o perfil clínico de mulheres submetidas ao exame Papanicolau, na USF-Brejinho, zona rural de um município do interior do Maranhão, no ano de 2011, foi realizado um estudo descritivo com resultados de exames papanicolau de 295 mulheres, por meio de um levantamento de dados, existentes em seus prontuários e livros de registro de enfermagem. De acordo com os resultados obtidos nesse trabalho, foram encontrados 2,1% de exames positivos para alterações celulares epiteliais escamosas e glandulares; destes, 0,6% referentes a atipias de significado indeterminado em células escamosas, 1,5% a atipias de significado indeterminado em células glandulares e, 1,25% com lesão intraepitelial cervical de baixo grau. Vale ressaltar que essas lesões, consideradas como precursoras do carcinoma de colo uterino, desempenham importante papel no processo de evolução para o câncer cervical. Isso demonstra a necessidade de um aporte às atividades de prevenção primária e de detecção precoce dessas lesões, na tentativa de minimizar as taxas de mortalidade atribuídas a essa patologia em nossa região.

However, these alements were useful as a mean of visual communication between the high classes, able to generate charters, and the rest of medieval society—the majority illiterate— who received those charters.

    Full Text Available Resumo A proposta deste artigo é pensar o lugar da testemunha como um lugar terceiro que o analista, na clínica do traumático, é capaz de sustentar. Nos sonhos traumáticos, segundo Ferenczi, já existe a convocação de um terceiro. Não se trata da testemunha da esfera do Direito, tampouco do lugar do pai ou da Lei simbólica. Trata-se de um terceiro espaço que pode ser chamado de potencial, espaço intersticial, indeterminado e informe no qual circula - e aos poucos ganha forma -, algo que a princípio seria incomunicável. Esse espaço permite e suporta a literalidade da narrativa testemunhal, seus titubeios, paradoxos e silêncios. Mais do que uma teoria do trauma, a noção de espaço potencial seria a grande contribuição da psicanálise às pesquisas teóricas e clínicas com sobreviventes de campos de extermínio, de situações de tortura e de violência.

Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos.

Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

    Introduction: In occupational medicine, medical care must be geared toward the prevention of worker health. However, occupational medical exams often seek only through rigorous screening, reduce absenteeism, and thus increase productivity. To meet this goal, many institutions include radiological examinations indiscriminately in their medical and expert evaluations, contrary to the principle of justification. Objective: To provide a reflection about the presence of radiological exams in occupational medical evaluations. Methodology: Literary review including legislation related to the research topic. Results: Portaria 453/98 ANVISA prohibits the performance of radiological examinations for employment or expert purposes, except in cases where the exam may bring a benefit to the health of the individual examined or to society. However, in some situations the Norma Regulamentadora number 7 of the Ministry of Labor and Employment provides for radiological exams as a parameter for monitoring occupational exposure. Article 168 of the Consolidation of Labor Laws also prescribes that additional examinations may be required, at the medical discretion, to determine the physical and mental fitness of the employee for the job. Conclusion: Although there are legal provisions that prohibit and others that allow radiological exams in medical occupational evaluations, companies and institutions should take into account that any radiological exam has a risk involved and should not request them in a compulsory and indiscriminate manner. Radiological exams are only permissible to elucidate the diagnostic hypothesis produced by clinical evaluation, in order to provide a real benefit for the individual.

    Curricular issues of subject Applied Mathematics to Social Sciences are studied in relation to university entrance exams performed in several Spanish regions between 2009-2014. By using quantitative and qualitative analyses, it has been studied how these exams align with curriculum and how they produce a washback on curriculum and teachers' work. Additionally, one questionnaire about teachers' practices has been performed, in order to find out how the exams are influencing teaching methodology development. Main results obtained show that evaluation is producing a bias on the official curriculum, substantially simplifying the specific orientation that should guide applied mathematics. Furthermore, teachers' practices are influenced by the exams, and they usually approach their teaching methodology to the frequent types of exams. Also, slight differences among the teachers lead to distinguish two behavioral subgroups. Results can also be useful in an international context, because of the importance of standardized exit exams in OECD countries.

    Full Text Available This paper introduces a framework for designing exam courses and highlights the importance of needs analysis in designing exam courses. The main objectives of this paper are to highlight the key role of needs analysis in designing exam courses, to offer a framework for designing exam courses, to show the language needs of different students for IELTS (International English Language Testing System exam, to offer an analysis of those needs and to explain how they will be taken into account for the design of the course. First, I will concentrate on some distinguishing features in exam classes, which make them different from general English classes. Secondly, I will introduce a framework for needs analysis and diagnostic testing and highlight the importance of needs analysis for the design of syllabus and language courses. Thirdly, I will describe significant features of syllabus design, course assessment, and evaluation procedures.

  20. Red vs. green: Does the exam booklet color matter in higher education summative evaluations? Not likely.

    Arthur, Winfred; Cho, Inchul; Muñoz, Gonzalo J

    2016-10-01

    We examined the so-called "red effect" in the context of higher education summative exams under the premise that unlike the conditions or situations where this effect typically has been obtained, the totality of factors, such as higher motivation, familiarity with exam material, and more reliance on domain knowledge that characterize high-stakes testing such as those in operational educational settings, are likely to mitigate any color effects. Using three naturally occurring archival data sets in which students took exams on either red or green exam booklets, the results indicated that booklet color (red vs. green) did not affect exam performance. From a scientific perspective, the results suggest that color effects may be attenuated by factors that characterize high-stakes assessments, and from an applied perspective, they suggest that the choice of red vs. green exam booklets in higher education summative evaluations is likely not a concern.

    Temporomandibular joint is one of the most complicated joints of the body and plays an important role in the head and neck system. One of the factors affecting the temporomandibular joint and lead to temporomandibular disorder is anxiety with all the events causing it. The aim of this study was to determine a relationship between anxiety and temporomandibular disorders. In this prospective study, subjects were randomly selected. One hundred and thirty pre-university students in Isfahan were evaluated with Ketel's test of anxiety, exam stress test and temporomandibular disorder questionnaires. The evaluation was done in two stages 10 months and 1 month prior to the university entrance exam (Konkour), clinical assessments consisted of masticatory muscles and sternocleidomastoid muscle palpation, temporomandibular joint palpation for pain and noise and its movement, and mouth opening limitations. The Wilcoxon rank test and paired t-test were used to analyze the data and the P value under 0.05 was considered significant. The level of anxiety and occurrence of temporomandibular disorders were increased between two stages and had the highest level in the second stage. There was a significant increase between two stages (Ptemporomandibular disorders and anxiety between the two stages can suggest a possible relationship between anxiety and temporomandibular disorders. Therefore, the effect of anxiety in triggering temporomandibular disorder symptoms is probable.

  3. Exame criminológico e psicologia: crise e manutenção da disciplina carcerária

    Directory of Open Access Journals (Sweden)

    Jefferson Cruz Reishoffer

    Full Text Available Resumo Em 2003, a Lei n° 10.792 retirou a obrigatoriedade de realização do exame criminológico, no âmbito da execução penal brasileira, alterando o rol de requisitos para fins de concessão de livramento condicional e de progressão de regime. Contudo, tal alteração legal não produziu efeitos significativos nas esferas judiciárias, pois, mais de dez anos depois, ainda há grande quantidade de solicitações para realização de tais exames como principal subsídio à decisão de juízes. Este artigo coloca em análise as estratégias de saber e os exercícios de poder que mantêm tais avaliações e a lógica criminalizante presente nos procedimentos carcerários, promovendo questionamentos à Psicologia, aos princípios presentes em seu código de ética e ao compromisso social da profissão.

    To validate The Johns Hopkins Adapted Cognitive Exam designed to assess and quantify cognition in critically ill patients. Prospective cohort study. Neurosciences, surgical, and medical intensive care units at The Johns Hopkins Hospital. One hundred six adult critically ill patients. One expert neurologic assessment and four measurements of the Adapted Cognitive Exam (all patients). Four measurements of the Folstein Mini-Mental State Examination in nonintubated patients only. Adapted Cognitive Exam and Mini-Mental State Examination were performed by 76 different raters. One hundred six patients were assessed, 46 intubated and 60 nonintubated, resulting in 424 Adapted Cognitive Exam and 240 Mini-Mental State Examination measurements. Criterion validity was assessed by comparing Adapted Cognitive Exam with a neurointensivist's assessment of cognitive status (ρ = 0.83, p validity was assessed by comparing Adapted Cognitive Exam with Mini-Mental State Examination in nonintubated patients (ρ = 0.81, p validity was assessed by surveying raters who used both the Adapted Cognitive Exam and Mini-Mental State Examination and indicated the Adapted Cognitive Exam was an accurate reflection of the patient's cognitive status, more sensitive a marker of cognition than the Mini-Mental State Examination, and easy to use. The Adapted Cognitive Exam demonstrated excellent interrater reliability (intraclass correlation coefficient = 0.997; 95% confidence interval 0.997-0.998) and interitem reliability of each of the five subscales of the Adapted Cognitive Exam and Mini-Mental State Examination (Cronbach's α: range for Adapted Cognitive Exam = 0.83-0.88; range for Mini-Mental State Examination = 0.72-0.81). The Adapted Cognitive Exam is the first valid and reliable examination for the assessment and quantification of cognition in critically ill patients. It provides a useful, objective tool that can be used by any member of the interdisciplinary critical care team to support

We have looked at the notion of the imperativeness of Law the central theme of the work -drawing on the views of Miguel Reale, for whom the juridical nonn cannot be reduced to a "command of a volitional nature", but rather the obligatory character of the juridical nonn arises from the pressure of social values.

    It is almost universally agreed that more frequent formative assessment (homework, clicker questions, practice tests, etc.) leads to better student performance and generally better course evaluations. There is, however, only anecdotal evidence that the same would be true for more frequent summative assessment (exams). There maybe many arguments against giving more exams, including the general "pain" associated with examinations, as well as reduced teaching time, since classroom sessions are dedicated to exams rather than lecturing. We present evidence that increasing the number of exams in fact does lead to better learning success, less cheating and guessing on homework, and better student course evaluations.

    There are several interesting astronomical topics that must be addressed in the High School and Elementary/Middle School in the disciplines of Geography and of Sciences. Among them, the topic of time zones which is one of the most important to understand the correlation of the Earth's rotation and its implications on daily activities of citizens in local scale, regional and global scales which involve problems of time differences. For the teaching of time zones in the lessons of Geography, for example, there are bi-dimensional representations of thematic maps of world time zones, textbooks and atlas. It happens that teachers face some difficulties to permit its students to view three-dimensionally this astronomical phenomenon from the textbooks available in schools. The aim of this paper is to present two proposals with low-cost materials, which allow the preparation of three-dimensional models for the teaching of time zones.

Para o ensino dos fusos horários nas aulas de Geografia, por exemplo, há representações bidimensionais de mapas temáticos de fusos horários mundiais, nos livros didáticos e nos atlas. Ocorre que os professores enfrentam algumas dificuldades para possibilitar aos seus alunos a visão tridimensional deste fenômeno astronômico, a partir dos materiais didáticos disponíveis nas escolas.

    Kondo, Osamu

    The percentage of students who go on to universities or junior colleges is over fifty percent which is more than half of high school students. However the nation's birthrate is in decline and the total number of university-age children shows a declining tendency. Hence we cannot expect an increase in the number of applicants in the future. On the other hand, the number of universities has been increasing year by year. The competition among universities to survive is very fierce. The diversification of entrance examination is a symbol of this competition. By diversifying entrance exams, universities aimed at the quality of excellent students in the beginning. However, they have changed their direction to pursue the quantity of students. As of Today the entrance examination is losing its original starting function which means most or all applicants can enter universities. It is time all of the universities return to its starting line.

    Phantoms are simulating objects of structures of the human body and can be applied in the quality control and calibration of radiological equipment. The aim of the work is the development of a cardiac anthropomorphic phantom to assist in the elaboration of protocols of dynamic studies that demonstrate the blood circulation inside the cardiac chambers. For the construction of the phantom was used latex, applied in layers on an anatomical model of heart, having been constructed the cardiac chambers and atrioventricular valves. Cardiac chambers were connected to the cannulas for fluid injection and simulation of the circulatory system. The constructed phantom presents anthropomorphic characteristics and allows the circulation of the fluid without reflux, but the thickness of the catheters used does not yet allow flows of greater order of magnitude. This phantom has the potential to be used in the dynamic simulation of cardiac exams, contributing to the elaboration and adequacy of computed tomography protocols

El día 15 de marzo de 2002, con motivo de la Cumbre Europea de Barcelona, Jorge Semprún reflexionaba, en las páginas de un conocido diario madrileño, sobre el significado que para él tenía ser europeo. Para ello emprendía tres "viajes intelectuales" a Viena, Praga y Buchenwald, los tres de gran significado histórico y cultural. Dado el interés del texto y del momento, me pareció entonces oportuno glosar algunos aspectos de aquel artículo, primero, para subrayar el valor de la aportación de Semprún, luego para corregir alguna inexactitud de carácter biográfico, debida posiblemente a la rapidez de la traducción, y, tercero, para ampliar con algún comentario la valiosa contribución de Sempnín, sobre todo en lo que concierne al sentido de Europa. En este texto se toma aquel comentario como punto de partida.The origins of this text are very specific. On 15 March 2002, on the occasion of the European Summit in Barcelona, and on the pages of a well-known Madrid newspaper, Jorge Semprún reflected on the meaning that being European had for him. To do this, he embarked on three "intellectual journeys" to Vienna, Prague and Buchenwald, all three of great historical and cultural significance. Given the interest of the text and of the moment, I considered it appropriate to comment on aspects of the article -firstly, to underline the value of Semprún's contribution; secondly, to correct certain biographical inaccuracies, possibly due to a hasty translation; and thirdly, to complement Semprún's valuable contribution, essentially concerning the meaning of Europe. This text takes that comment as its starting point.

Em virtude de serem substâncias amplamente utilizadas e terem como principal via de excreção a urinária, este tratamento pode provocar variações nos resultados dos parâmetros urinários. Portanto, este estudo tem a finalidade de avaliar a interferência causada pelo uso de hipoglicemiantes no exame de urina. Para esta investigação, foi feita uma pesquisa bibliográfica em diferentes bases de dados, selecionando os artigos pertinentes ao tema: diabetes, interferências laboratoriais e tratamento farmacológico. Os HO podem ser classificados em três grupos de acordo com o mecanismo de ação: estimuladores de insulinas pelo pâncreas, como sulfoniluréias e metiglinidas; as sensibilizadoras de insulina, são as biguanidas, as tiazolidinedionas e as redutoras da absorção de carboidratos, que são as inibidoras da alfa-glicosidase. O exame de urina é uma ferramenta complementar no controle da DM devido a sua fácil coleta e baixo custo. As classes de hipoglicemiantes orais identificados como potencialmente interferentes no exame de urina foram as biguanidas (metformina e as sulfoniluréias (tobultamida, tolazamida, glicazida, clorpropramida.

    Turjamaa, Riitta; Hynynen, Marja-Anneli; Mikkonen, Irma; Ylinen, Eeva-Riitta

    2018-03-01

    The purpose of this articl is to explore nursing students' experiences of dialogic group oral exams used in the assessment of a medical nursing course. We discuss a small-group, educator-facilitated exam (dialogue exam). The data were gathered in April 2015 via an online survey including open questions. The participants were nursing students (n = 58) at a University of Applied Sciences. The data were subjected to inductive content analysis. The results suggest that students' experiences of the dialogue exam can be represented by four themes: context bound dynamics, new shared understanding, verified competences and holistic nursing care. The students liked the dialogue exam format, preferring it to the traditional individual written exam. The prerequisite for successful use of the dialogue exam format is that candidates perceived the exam situation as safe. Students need to be given information about the schedule and assessment criteria beforehand and should have some experience of the format. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available RESUMO: Este estudo teve como objetivo apresentar de forma detalhada dados morfológicos e morfométricos da articulação umerorradioulnar de cães de raça definida avaliados por meio de exames físicos, radiográficos e tomográficos. A amostra dessa pesquisa constituiu-se de 44 cotovelos de cães com idades variadas. Para análise de informações obtidas, o coeficiente kappa e de correlação interclasse e associação foram realizados. Constatou-se que o desempenho individual de cada projeção radiográfica teve pobre concordância com o exame tomográfico; não houve concordância entre os observadores para as mensurações do ângulo da incisura ulnar ao exame radiográfico e tomográfico. Porém houve boa/moderada concordância para mensuração da incongruência radioulnar no plano sagital entre os observadores. Concluiu-se que nenhuma das cinco incidências radiográficas foi superior para análise radiográfica, uma vez que cada projeção apresentou melhor identificação de um compartimento do cotovelo. Medidas ao exame tomográfico para incongruência radioulnar não apresentaram reprodutibilidade no plano de reconstrução frontal, entretanto no corte sagital apresentaram boa e moderada concordância entre os observadores e que a mensuração do ângulo da incisura ulnar não apresentou repetibilidade ao exame radiográfico e nem reprodutibilidade ao exame tomográfico. Esses resultados contribuem para melhor utilização de cada exame de acordo com a região a ser avaliada bem como ressaltam a necessidade da somatória de múltiplos exames de imagem para a correta avaliação desta afecção.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória tem como objetivos diminuir a morbimortalidade do paciente cirúrgico, o custo do atendimento perioperatório e a ansiedade pré-operatória. A partir da avaliação clínica deve-se definir a necessidade de exames complementares e estratégias para reduzir o risco anestésico-cirúrgico. O objetivo deste trabalho foi avaliar o benefício de exames de rotina pré-operatório de pacientes de baixo risco em cirurgias de pequeno e médio porte. MÉTODOS: Trata-se de um estudo descritivo, transversal, com 800 pacientes atendidos no consultório de avaliação pré-anestésica do Hospital Santo Antonio, Salvador, BA. Foram incluídos pacientes de 1 a 45 anos, estado físico ASA I, que seriam submetidos a cirurgias eletivas de pequeno e médio porte. Avaliaram-se alterações no hemograma, coagulograma, eletrocardiograma, RX de tórax, glicemia, função renal e dosagem de sódio e potássio e as eventuais mudanças de conduta que ocorreram decorrentes dessas alterações. RESULTADOS: Dos 800 pacientes avaliados, 97,5% fizeram hemograma, 89% coagulograma, 74,1% eletrocardiograma, 62% RX de tórax, 68% glicemia de jejum, 55,7% dosagens séricas de ureia e creatinina e 10,1% dosagens de sódio e potássio séricos. Desses 700 pacientes, 68 (9,71% apresentaram alteração nos exames pré-operatórios de rotina e apenas 10 (14,7% dos considerados alterados tiveram conduta pré-operatória modificada, ou seja, solicitação de novos exames, interconsulta ou adiamento do procedimento. Nenhuma das cirurgias foi suspensa. CONCLUSÃO: Observou-se que excessivos exames complementares são solicitados no pré-operatório, mesmo em pacientes jovens, de baixo risco cirúrgico, com pouca ou nenhuma interferência na conduta perioperatória. Exames aboratoriais padronizados não são bons instrumentos de screening de doenças, além de gerar gastos elevados e desnecessários.

  4. The new AP Physics exams: Integrating qualitative and quantitative reasoning

    Elby, Andrew

    2015-04-01

    When physics instructors and education researchers emphasize the importance of integrating qualitative and quantitative reasoning in problem solving, they usually mean using those types of reasoning serially and separately: first students should analyze the physical situation qualitatively/conceptually to figure out the relevant equations, then they should process those equations quantitatively to generate a solution, and finally they should use qualitative reasoning to check that answer for plausibility (Heller, Keith, & Anderson, 1992). The new AP Physics 1 and 2 exams will, of course, reward this approach to problem solving. But one kind of free response question will demand and reward a further integration of qualitative and quantitative reasoning, namely mathematical modeling and sense-making--inventing new equations to capture a physical situation and focusing on proportionalities, inverse proportionalities, and other functional relations to infer what the equation ``says'' about the physical world. In this talk, I discuss examples of these qualitative-quantitative translation questions, highlighting how they differ from both standard quantitative and standard qualitative questions. I then discuss the kinds of modeling activities that can help AP and college students develop these skills and habits of mind.

    This work aims to investigate the dose descriptor, volumetric Computed Tomography Dose Index (CTDI), a pediatric patients sample undergoing to skull CT, comparing the results with the diagnostic reference levels of the literature. Were collected volumetric CTDI values of all skull CT exams performed retrospectively in children of 0-10 years of age in a period of 12 months in a large hospital size. Patients, in a total of 103, were divided into four groups, where the criterion of separation used was age, trying to use the same division used in international references dose descriptors. In all acquisitions we used the pediatric protocol and the Automatic Exposure Control (AEC) available on the equipment. The CDTI values, with and without the use of AEC for pediatric studies, were compared. There was a reduction of approximately 100% in the absorbed dose value due to the use of the AEC. From the data collected and analyzed in this work, it is concluded that the use of dose reduction systems is relevant, such as the Care Dose, to maintain volumetric CTDI values within the reference levels. Also it is important the observation of range of children age to the appropriate choice of parameters used in the test protocol. The values obtained are according to the diagnostic reference levels from the literature

    Full Text Available Auricular acupuncture (AA is effective in the treatment of preoperative anxiety. The aim was to investigate whether AA can reduce exam anxiety as compared to placebo and no intervention. Forty-four medical students were randomized to receive AA, placebo, or no intervention in a crossover manner and subsequently completed three comparable oral anatomy exams with an interval of 1 month between the exams/interventions. AA was applied using indwelling fixed needles bilaterally at points MA-IC1, MA-TF1, MA-SC, MA-AT1 and MA-TG one day prior to each exam. Placebo needles were used as control. Levels of anxiety were measured using a visual analogue scale before and after each intervention as well as before each exam. Additional measures included the State-Trait-Anxiety Inventory, duration of sleep at night, blood pressure, heart rate and the extent of participant blinding. All included participants finished the study. Anxiety levels were reduced after AA and placebo intervention compared to baseline and the no intervention condition (p < 0.003. AA was better at reducing anxiety than placebo in the evening before the exam (p = 0.018. Participants were able to distinguish between AA and placebo intervention. Both AA and placebo interventions reduced exam anxiety in medical students. The superiority of AA over placebo may be due to insufficient blinding of participants.

  9. Multiple-Choice Exams: An Obstacle for Higher-Level Thinking in Introductory Science Classes

    Stanger-Hall, Kathrin F.

    2012-01-01

    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities. PMID:22949426

    The selection of the contrast agent used during fluoroscopic exams is an important clinical decision. The purpose of this article is to document the usage of a nonionic, water-soluble contrast (iohexol) and barium contrast in adult patients undergoing fluoroscopic exams of the pharynx and/or esophagus and provide clinical indications for the use of each. For 1 year, data were collected on the use of iohexol and barium during fluoroscopic exams. The contrast agent used was selected by the speech language pathologist (SLP) or the radiologist based on the exam's indications. A total of 1,978 fluoroscopic exams were completed in the 12-month period of documentation. Of these exams, 60.6 % were completed for medical reasons and 39.4 % for surgical reasons. Fifty-five percent of the exams were performed jointly by a SLP and a radiologist and 45 % were performed by a radiologist alone. Aspiration was present in 22 % of the exams, vestibular penetration occurred in 38 %, extraluminal leakage of contrast was observed in 4.6 %, and both aspiration and leakage were seen in 1 % of the exams. In cases with aspiration, iohexol was used alone in 8 %, iohexol and barium were both used in 45 %, and barium was used alone in 47 %. In cases with extraluminal leakage, iohexol was used alone in 58 %, iohexol and barium were both used in 31 %, and barium was used alone in 11 %. No adverse effects were seen with the use of iohexol. When barium was used in cases of aspiration and extraluminal leakage, the amount of aspirated barium was small and the extraluminal barium in the instances of leakage was small. Iohexol is a useful screening contrast agent and can safely provide information, and its use reduces the risk of aspiration and the chance of leakage of large amounts of barium.

    Khansari, Parto S; Coyne, Leanne

    The study investigates students' perceptions of the value of implementing a team exam to enhance learning prior to a summative assessment. Team exams are similar to midterm exams, except that answering questions is a team effort. Data was collected from second year pharmacy students at California Northstate University College of Pharmacy (CNUCOP) through a self-administered online survey. The survey questions included closed-ended questions to evaluate students' perception on preparedness for a summative assessment and to rank advantages and disadvantages of the team exams. Of the 40 students who completed the survey (38% response rate), 100% of participants agreed that having a team exam prior to a major exam made them feel more prepared for a major summative exam. Ninety-seven percent of students believed that the team exam helped them to identify gaps in their knowledge and 85% agreed that taking a team exam reinforced their knowledge by teaching other students. The survey results did not identify any major disadvantages to holding a team exam. Students perceived that taking a team exam prior to a midterm exam is an effective approach to review the course contents and identify areas of improvement. Copyright © 2017.

    Full Text Available Continuous assessment aims to enhance student learning and understanding of a subject and so achieve better educational outcomes. We investigated how continuous assessment grades affected final exam grades. Using a dataset for six academic post-Bologna Process years (2009-2015 for a first-year undergraduate microeconomics course offered at a Spanish public university, we examined conditional dependence between continuous assessment and final exam grades. Our results would indicate a limited contribution of continuous assessment results to final exam results: the probability of the final exam performance improving on the continuous assessment grade was lower than the probability of the opposite occurring. A consistent exception, however, was students who obtained an A grade for continuous assessment. Our results would cast some doubt on the beneficial effects of continuous assessment advocated by the Bologna Process.

    Objectives: Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students...... at risk of later psychiatric events. Methods: Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical...... reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves...

    Full Text Available The current study examined the effect of high school graduation exams on states' graduation rates, states' aggregated SAT scores, and individual students' SAT scores. Three data sources were used: One source identified states requiring a standardized test for graduation; the NCES provided state aggregated data on graduation rates for the class of 2002; and the College Board provided its 2001 SAT database for all test-takers. After controlling for students' demographic characteristics (e.g., race, family education and income, GPA and class rank, regression analyses revealed that states requiring graduation exams had lower graduation rates and lower SAT scores. Individually, students from states requiring a graduation exam performed more poorly on the SAT than did students from states not requiring an exam. The impact of high stakes tests' on students' motivation to stay in school and on the teaching of critical thinking skills (tested by the SAT are discussed.

In addition, we examined the relationship between exam performance and the number of clinical tutors per student.Materials and methods: A retrospective review of the logbooks of first and third clinical year medical students at the Faculty of Medicine, Kuwait University, was undertaken during their surgery rotation during the academic year 2012–2013.Results: Logbooks of 184 students were reviewed and analyzed. There were 92 and 93 students in the first and third clinical years, respectively. We did not identify any correlation between the number of clinical encounters and clinical exam or multiple-choice exam scores; however, there was an inverse relationship between the number of clinical tutors encountered during a rotation and clinical exam scores.Conclusion: Overall, there was no correlation between the volume of self-reported clinical encounters and exam scores. Furthermore, an inverse correlation between the number of clinical tutors encountered and clinical exam scores was detected. These findings indicate a need for reevaluation of the way logbook data are entered and used as an assessment tool. Keywords: OSCE, assessment, Kuwait, universities, rotation

Neste artigo, busco entender o significado dado a estas menções no contexto das narrativas de experiências da medicalização da gravidez e parto destas mulheres. Entendo estas histórias como formas de expressão não apenas como um meio de expor a experiência, mas também como modos de estruturá-la. Proponho ver estas histórias como maneiras de articular biografias a significados culturais de pessoa, corpo, gênero e maternidade, dando, portanto, sentidos específicos às experiências de parto destas mulheres. Elas oferecem também uma compreensão da experiência do sistema médico, mostrando como as mulheres negociam sentidos de práticas e diagnósticos ao longo de suas gestações e partos.

  11. Integrity of Disposable Nitrile Exam Gloves Exposed to Simulated Movement

    Phalen, Robert N.; Wong, Weng Kee

    2011-01-01

    Every year, millions of health care, first responder, and industry workers are exposed to chemical and biological hazards. Disposable nitrile gloves are a common choice as both a chemical and physical barrier to these hazards, especially as an alternative to natural latex gloves. However, glove selection is complicated by the availability of several types or formulations of nitrile gloves, such as low-modulus, medical-grade, low-filler, and cleanroom products. This study evaluated the influence of simulated movement on the physical integrity (i.e., holes) of different nitrile exam glove brands and types. Thirty glove products were evaluated out-of-box and after exposure to simulated whole-glove movement for 2 hr. In lieu of the traditional 1-L water-leak test, a modified water-leak test, standardized to detect a 0.15 ± 0.05 mm hole in different regions of the glove, was developed. A specialized air inflation method simulated bidirectional stretching and whole-glove movement. A worst-case scenario with maximum stretching was evaluated. On average, movement did not have a significant effect on glove integrity (chi-square; p=0.068). The average effect was less than 1% between no movement (1.5%) and movement (2.1%) exposures. However, there was significant variability in glove integrity between different glove types (p ≤ 0.05). Cleanroom gloves, on average, had the highest percentage of leaks, and 50% failed the water-leak test. Low-modulus and medical-grade gloves had the lowest percentages of leaks, and no products failed the water-leak test. Variability in polymer formulation was suspected to account for the observed discrepancies, as well as the inability of the traditional 1-L water-leak test to detect holes in finger/thumb regions. Unexpectedly, greater than 80% of the glove defects were observed in the finger and thumb regions. It is recommended that existing water-leak tests be re-evaluated and standardized to account for product variability. PMID:21476169

    The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

    Although many educational institutions allow students to resit exams, a recently proposed mathematical model suggests that this could lead to a dramatic reduction in study-time investment, especially in rational students. In the current study, we present a modification of this model in which we included some well-justified assumptions about learning and performance on multiple-choice tests, and we tested its predictions in two experiments in which participants were asked to invest fictional study time for a fictional exam. Consistent with our model, the prospect of a resit exam was found to promote lower investments of study time for a first exam and this effect was stronger for participants scoring higher on the cognitive reflection test. We also found that the negative effect of resit exams on study-time investment was attenuated when access to the resit was made uncertain by making it probabilistic or dependent on obtaining a minimal, non-passing grade for the first attempt. Taken together, these results suggest that offering students resit exams may compromise the achievement of learning goals, and they raise the more general implication that second chances promote risky behavior.

    The latest report by the National Crime Records Bureau has positioned Tamil Nadu as the Indian state with highest suicide rate. At least in part, this is happening due to exam pressure among adolescents, emphasizing the imperative need to understand the pattern of anxiety and various factors contributing to it among students. The present study was conducted to analyze the level of state anxiety among board exam attending school students in Tamil Nadu, India. A group of 100 students containing 50 boys and 50 girls from 10th and 12th grades participated in the study and their state anxiety before board exams was measured by Westside Test Anxiety Scale. We found that all board exam going students had increased level of anxiety, which was particularly higher among boys and 12th standard board exam going students. Analysis of various demographic variables showed that students from nuclear families presented higher anxiety levels compared to their desired competitive group. Overall, our results showing the prevalence of state anxiety among board exam going students in Tamil Nadu, India, support the recent attempt taken by Tamil Nadu government to improve student's academic performance in a healthier manner by appointing psychologists in all government schools.

    The ExaMe system for the evaluation of targeted knowledge has been in development since 1998. The new features of the ExaMe system are introduced in this paper. Especially, the new three-layer architecture is described. Besides the system itself, the properties of fixed tests in the ExaMe system are studied. In special detail, the reliability of the fixed tests is discussed. The theory background is explained and some limitations of the reliability are pointed out. Three characteristics used for estimation of reliability of educational tests are discussed: Cronbach's alpha, standardized item alpha and split half coefficient. The relation between these characteristics and reliability and between characteristics themselves is investigated. In more detail, the properties of Cronbach's alpha, the characteristics mostly used for the estimation of reliability, are discussed. A confidence interval is introduced for the characteristics. Since 2000, the serviceability of the ExaMe evaluation system as the supporting evaluation tool has been repeatedly shown at the courses of Ph.D. studies in biomedical informatics at Charles University in Prague. The ExaMe system also opens new possibilities for self-evaluation and distance learning, especially when connected with electronic books on the Internet. The estimation of reliability of tests contains some limitations. Keeping them in mind, we can still get some information about the quality of certain educational tests. Therefore, the estimation of reliability of the fixed tests is implemented in the ExaMe system.

    Academic exam stress is known to compromise sleep quality and alter drug consumption in university students. Here we evaluated if sleeping problems and changes in legal drug consumption during exam stress are interrelated. We used the Pittsburgh Sleep Quality Index (PSQI) to survey sleep quality before, during, and after an academic exam period in 150 university students in a longitudinal questionnaire study. Self-reports of alcohol, caffeine, and nicotine consumption were obtained. The Perceived Stress Questionnaire (PSQ-20) was used as a measure of stress. Sleep quality and alcohol consumption significantly decreased, while perceived stress and caffeine consumption significantly increased during the exam period. No significant change in nicotine consumption was observed. In particular, students shortened their time in bed and showed symptoms of insomnia. Mixed model analysis indicated that sex, age, health status, as well as the amounts of alcohol and caffeine consumed had no significant influence on global sleep quality. The amount of nicotine consumed and perceived stress were identified as significant predictors of diminished sleep quality. Nicotine consumption had a small-to-very-small effect on sleep quality; perceived stress had a small-to-moderate effect. In conclusion, diminished sleep quality during exam periods was mainly predicted by perceived stress, while legal drug consumption played a minor role. Exam periods may pose an interesting model for the study of stress-induced sleeping problems and their mechanisms.

    Due to the use of radiopharmaceutical positron-emitting in PET exam and realization of tomography by x-ray transmission in CT examination, an increase of dose with hybrid PET/CT technology is expected. However, differences of doses have been reported in many countries for the same type of procedure. It is expected that the dose is an influent parameter to standardize the protocols of PET/CT. This study aimed to estimate the effective doses and absorbed in 65 patients submitted to oncological Protocol in a nuclear medicine clinic in Rio de Janeiro, considering the risk of induction of cancer from the scan. The CT exam-related doses were estimated with a simulator of PMMA and simulated on the lmPACT resistance, which for program effective dose, were considered the weight factors of the lCRP 103. The PET exam doses were estimated by multiplying the activity administered to the patient with the ICRP dose 80 factors. The radiological risk for cancer incidence were estimated according to the ICRP 103. The results showed that the effective dose from CT exam is responsible for 70% of the effective total in a PET/CT scan. values of effective dose for the PET/CT exam reached average values of up to 25 mSv leading to a risk of 2, 57 x 10{sup -4}. Considering that in staging of oncological diseases at least four tests are performed annually, the total risk comes to 1,03x 10{sup -3}.

    Pre-exam anxiety syndrome is a common condition occurring in pre-exam students and directly affects their examination performance and physical state. Wrist-ankle acupuncture has significant therapeutic effects in treating mental disorders and may also relieve the symptoms of pre-exam anxiety syndrome. To assess the therapeutic effect of wrist-ankle acupuncture on pre-exam anxiety syndrome. A total of 60 students who met the inclusion criteria of pre-exam anxiety syndrome were enrolled from a university in Shanghai and they were randomly divided into treatment group and control group. There were 30 cases in each group, and no case failed to follow-up. In the treatment group, wrist-ankle acupuncture was adopted to point upper 1 bilaterally (impression between flexor carpi ulnaris tendon and ulnar margin), and there was no requirement for Deqi (arrival of qi). In the control group, sham acupuncture was adopted. The treatment was applied 3 times totally in both groups one week before the exam, once every other day, each time with the needles retained for 30 min. The therapeutic effects were compared between two groups. Before and after 3 treatments, Sarason Test Anxiety Scale (TAS) and Expectation and Treatment Credibility Scale (ETCS) were measured and evaluated. The therapeutic effect experienced by the treatment group was better than that of the control group (PETCS before treatment between the two groups. The scores of TAS after treatment in two groups were higher than those before treatment (PETCS than those in the control group (P<0.05, P<0.01). No adverse reaction was reported. Wrist-ankle acupuncture can relieve the symptoms of pre-exam anxiety syndrome significantly, and this therapy is highly safe.

    One of the frequent questions in obstetric practice is to determine placental vascular changes that may account for abnormal Doppler flow velocity alterations in maternal uterine vessels from women and fetuses without pregnancy pathology. A retrospective morphometric study was realized using 27 placentas from patients submitted for Doppler flow velocity exam during pregnancy. The placentas were morphologically examined using hematoxylin-eosin staining. Measurements of villi were made with the use of a video camera coupled to a common light microscope and a computer with automatic image analyzing software. Of the 27 placentas, 13 (48%) were of patients showing unaltered Doppler and 14 (52%) showing altered Doppler. The number of stem villi vessels was significantly larger in the placentas of patients with Doppler exam alterations (P = 0.003). This group also presented greater stem villi vessel thickness, although without significant difference. The number of intermediary and terminal villi vessels was greater in the placentas of patients with altered Doppler exams (P < 0.001), and a greater terminal villi area was observed in these cases (P < 0.001). The morphological proof that uterine artery Doppler flow velocity exam alterations are associated with placental vascular alterations demonstrates the importance of this exam during prenatal care, even in the absence of maternal-fetal alterations.

    [Purpose] The purpose of this study was to examine the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam as a clinical tool for quantifying upper extremity function in persons with Parkinson's disease. [Subjects and Methods] Thirty-two persons with idiopathic Parkinson's disease participated in this study. This study measured two clinical outcomes, the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam, to investigate the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam. [Results] The box-and-block test on the more affected side was positive relationship with the box-and-block test on the less affected side. The Unified Parkinson's Disease Rating Scale-motor exam score had a negative correlation with the box-and-block test results for both sides. [Conclusion] A positive association was noted between manual dexterity and motor function in patients with idiopathic Parkinson disease. The results of this study suggest that the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam are good clinical measures that quantify upper extremity function and are necessary for the accurate evaluation of patients and to plan intervention strategies.

    2011-06-01

    Full Text Available Learners studying for exams sometimes show a lack of awareness in their abilities as tested through the framework of that exam. Instead, such learners focus on the score obtained in exams, and exam preparation includes using textbooks, online materials and timed use of past papers. The purpose of exam-focused flexible self-directed learning modules (FSDLMs at Kanda University of International Studies have been designed to address this by developing learners’ ability to identify their strengths and weaknesses, to make informed decisions about their own learning, and to improve their test-taking skills. Each FSDLM has at its core a diagnostic for learners to use for self-evaluation, often with guidance from a learning advisor. This process leads to the setting of clear goals and the development and implementation of an individual learning plan through a variety of dialogues. Learners have the potential to transfer this skill beyond examination preparation to other areas of learning. In other words, learners’ awareness of needs analysis, planning, implementation and evaluation is fostered with a view to developing their language learning ability within and beyond this module.

Entretanto pode haver relutância por parte dos pacientes em relação à presença do residente durante sua consulta e exame físico. Este estudo visa avaliar a visão do paciente quanto a este aspecto do aprendizado prático do residente de coloproctologia. MÉTODOS: Cem pacientes consecutivos responderam , de forma voluntária e anônima a um questionário após a realização de exame proctológico com a aprticipação de residentes em coloproctologia em ambulatório de instituição privada. Foram investigados, sexo, idade, cor, estado civil e nível educacional e sócio-econômico, assim como a visão do paciente em relação à presença de residentes durante o exame proctológico, procurando-se identificar razões para a sua aceitação ou recusa durante a consulta. As respostas foram analisadas usando-se teste do qui-quadrado e o teste t de Student. RESULTADOS: Observou-se que 87% dos pacientes aceitaram bem a participação do residente no exame proctológico, enquanto 1% respondeu que recusaria sua presença. Onze por cento se mostraram indiferentes em relação à presença do residente e um paciente não respondeu. Não houve diferença significativa em relação às variáveis estudadas no que diz respeito à presença do residente durante o exame proctológico, exceto para estado civil, uma vez que uma taxa maior de pacientes casados aceitou o residente. A principal razão para a aceitação foi contribuir para a formação médica, enquanto que a recusa esteve relacionado à perda da privacidade. CONCLUSÃO: De um modo geral, os residentes são bem aceitos no ambulatório de coloproctologia em uma instituição privada. O conhecimento das razões para sua aceitação ou recusa podem favorecer posturas que facilitem a aceitação e minimizem a recusa.Residents exposure to

    The Indonesian Physics national-exams are end-of-course summative assessments that could be utilized to support the assessment for learning in physics educations. This paper discusses the development and evaluation of a testlet generator based on a re-engineering of Indonesian physics national exams. The exam problems were dissected and decomposed into testlets revealing the deeper understanding of the underlying physical concepts by inserting a qualitative question and its scientific reasoning question. A template-based generator was built to facilitate teachers in generating testlet variants that would be more conform to students' scientific attitude development than their original simple multiple-choice formats. The testlet generator was built using open source software technologies and was evaluated focusing on the black-box testing by exploring the generator's execution, inputs and outputs. The results showed the correctly-performed functionalities of the developed testlet generator in validating inputs, generating testlet variants, and accommodating polytomous item characteristics.

    Full Text Available We introduced voluntary wiki-based exercises to a long-running cognitive psychology course, part of the core curriculum for an undergraduate degree in psychology. Over 2 yearly cohorts, students who used the wiki more also scored higher on the final written exam. Using regression analysis, it is possible to account for students’ tendency to score well on other psychology exams, thus statistically removing some obvious candidate third factors, such as general talent or enthusiasm for psychology, which might drive this correlation. Such an analysis shows that both high- and low-grading students who used the wiki got higher scores on the final exam, with engaged wiki users scoring an average of an extra 5 percentage points. We offer an interpretation of the mechanisms of action in terms of the psychological literature on learning and memory.

    The present study aims at analyzing the meanings attributed to the digital rectal exam, seeking to problematize questions underlying the masculine discourse on the basis of aspects of the hegemonic masculinity model. Semi-structured interviews were held with 28 men in the city of Rio de Janeiro, in 2004. Among the main results is the idea that the digital rectal exam is something that violates an interdicted space, something that compromises the current understanding of masculinity, shall say, the digital rectal exam does not only affect the prostate, it also affects the masculinity, puts it to shame. We conclude that for understanding and problematizing the questions related to the prostate cancer prevention in special, and to the question of taking care of oneself from the masculine perspective in general, we need to consider the structural and symbolic aspects that underlie these questions.

    One of the challenges of multidetector computerized tomography is to minimize the risk of ionizing radiation using optimized protocols since higher doses are necessary to obtain high image quality. It was also noted that, due to the geometry in image acquisition using MDCT becomes necessary to estimate dose values consistent with the hypothesis clinically and with the specificities of the tomographic equipment. The aim of this study was to estimate the doses in abdomen exams from the data recorded on the MDCT console and dimensions obtained from DICOM images of patients undergoing different clinical protocols. Were collected, from the image DICOM of 101 exams, values of the dose length product (DLP) provided by Philips Health Care - Brilliance 64 equipment console, in order to relate them with the dose values obtained by means of thermoluminescent dosimeters ( TLD ) of CasSo{sub 4}:Mn placed on the surface of a cylindrical simulator abdomen acrylic manufactured under the technical - operational conditions for a typical abdomen exam. From the data obtained, it was possible to find a factor of 1.16 ( 5 % ) indicating that the DLP values Brilliance 64 console underestimate the doses and this should be used with correction factor to estimate the total dose of the patient.

    2016-01-01

    Medication administration is an important task of registered nurses. According to previous studies, nurses lack theoretical knowledge and drug calculation skills and knowledge-based mistakes do occur in clinical practice. Finnish health care organizations started to develop a systematic verification processes for medication competence at the end of the last decade. No studies have yet been made of nurses' theoretical knowledge and drug calculation skills according to these online exams. The aim of this study was to describe the medication competence of Finnish nurses according to theoretical and drug calculation exams. A descriptive correlation design was adopted. Participants and settings All nurses who participated in the online exam in three Finnish hospitals between 1.1.2009 and 31.05.2014 were selected to the study (n=2479). Quantitative methods like Pearson's chi-squared tests, analysis of variance (ANOVA) with post hoc Tukey tests and Pearson's correlation coefficient were used to test the existence of relationships between dependent and independent variables. The majority of nurses mastered the theoretical knowledge needed in medication administration, but 5% of the nurses struggled with passing the drug calculation exam. Theoretical knowledge and drug calculation skills were better in acute care units than in the other units and younger nurses achieved better results in both exams than their older colleagues. The differences found in this study were statistically significant, but not high. Nevertheless, even the tiniest deficiency in theoretical knowledge and drug calculation skills should be focused on. It is important to identify the nurses who struggle in the exams and to plan targeted educational interventions for supporting them. The next step is to study if verification of medication competence has an effect on patient safety. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students at risk of later psychiatric events. Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves for unadjusted associations and multivariable cause-specific Cox proportional hazard analyses for adjusted hazard ratios (HRs). We identified 12,147 healthy students with exam-related beta-blocker use and 12,147 matched healthy students with no current or prior use of beta-blockers (median age, 19 years; 80.3% women). Among all healthy students, 0.14% had a first-time prescription for a beta-blocker during the exam period with the highest proportion among students aged 19 years (0.39%). Eighty-one percent of the students filled only that single prescription for a beta-blocker during follow-up. During follow-up, 2225 (18.3%) beta-blocker users and 1400 (11.5%) nonbeta-blocker users were prescribed an antidepressant (p beta-blocker users and 658 (5.4%) nonbeta-blocker users were prescribed a psychotropic drug (p beta-blocker users and 6 (0.05%) nonbeta-blocker users attempted suicide (p = 0.03).

    Full Text Available INTRODUÇÃO: A retocele é causa comum de constipação por defecação obstruída. Freqüentemente está relacionada com outras causas de defecação obstruída, e os exames de fisiologia anal são importantes para o diagnóstico preciso da causa de constipação intestinal. OBJETIVO: observar a influência da retocele nos exames de fisiologia anal, e a necessidade da realização desses após o diagnóstico da retocele. MÉTODO: Para este trabalho foram estudados 40 pacientes com diagnóstico de defecação obstruída. Todos os pacientes foram submetidos aos exames de manometria, sensibilidade retal, eletromiografia, latência do nervo pudendo e proctografia, e foram separados em 2 grupos: portadores e não portadores de retocele . Foram encontrados 18 pacientes com retocele, e o diagnóstico mais freqüentemente associado foi o anismus . Em relação aos exames foi encontrada diferença significante apenas na proctografia no ângulo ano retal, demonstrando que a presença de retocele não interferiu nos resultados de exames de fisiologia anal quando comparados com outros constipados, mas esteve associada a outras causas de constipação, como anismus que necessita de outro tipo de tratamento. CONCLUSÃO: A retocele não interferiu nos valores dos exames de fisiologia anal, mas esteve associada a outros diagnósticos, sendo importante a realização dos mesmos.INTRODUCTION: Rectocele is a common cause of constipation for obstructed defecation.

  18. A history and overview of the certification exam for medical dosimetrists

    2005-01-01

    During the last century, the creation and implementation of board certification has had a powerful impact on the medical community. Board certification has helped to shape the scope and practice of medical professionals and the care they provide, as well as to influence the way the health insurance industry sets standards for reimbursement. One profession that offers board certification to its members is medical dosimetry. The Medical Dosimetrist Certification Board exam has been administered since 1988 and its content covers a broad spectrum of information from the radiation therapy sciences. The exam has strict application requirements and is rather difficult to pass. Those who pass the exam can then call themselves Certified Medical Dosimetrists. For data purposes of this study, several members of the dosimetry community were solicited to participate in a survey regarding the exam's content and history, and to provide relevant statistical data. Currently 2,177 medical dosimetrists are board certified, with an additional 1,500 estimated to be working without certification. Although board certification is not currently required to practice medical dosimetry, new legislation known as the CARE Bill could change this. The CARE Bill, if passed, would mandate nationwide compulsory licensure and/or certification for medical dosimetrists and other medical professionals who want to work in radiation-related health care. Health maintenance organizations and other insurance carriers may likewise require certification for reimbursement purposes

    Luckie, Douglas B.; Rivkin, Aaron M.; Aubry, Jacob R.; Marengo, Benjamin J.; Creech, Leah R.; Sweeder, Ryan D.

    2013-01-01

    We studied gains in student learning over eight semesters in which an introductory biology course curriculum was changed to include optional verbal final exams (VFs). Students could opt to demonstrate their mastery of course material via structured oral exams with the professor. In a quantitative assessment of cell biology content knowledge, students who passed the VF outscored their peers on the medical assessment test (MAT), an exam built with 40 Medical College Admissions Test (MCAT) questions (66.4% [n = 160] and 62% [n = 285], respectively; p students performed better on MCAT questions in all topic categories tested; the greatest gain occurred on the topic of cellular respiration. Because the VF focused on a conceptually parallel topic, photosynthesis, there may have been authentic knowledge transfer. In longitudinal tracking studies, passing the VF also correlated with higher performance in a range of upper-level science courses, with greatest significance in physiology, biochemistry, and organic chemistry. Participation had a wide range but not equal representation in academic standing, gender, and ethnicity. Yet students nearly unanimously (92%) valued the option. Our findings suggest oral exams at the introductory level may allow instructors to assess and aid students striving to achieve higher-level learning. PMID:24006399

A cross-sectional study was designed; using a self-administered twenty-two item online questionnaire for the students' convenience and easy response disclosure. Data were analyzed using Statistical Package for Social Science (SPSS) version 13®. A total of N = 1596 students participated in this survey, of whom 829 (51.9%) were university students and 767 (48.1%) were high school students. Overall, 80.0% of the respondents disclosed the use of OTC non-steroidal anti-inflammatory drugs for headache and pain relief. In addition, other substances used during the exams were Energy Drinks (5.0%), Flu Medication (5.0%), Vitamins (5.0%) and Antibiotics (5.0%). Female students were found to be more knowledgeable about safety issues concerning the use of OTC medicines (5.11 ± 1.27, p = media were the main factors disclosed by the respondents that may result in an increase in the use of OTC products. The use of OTC medicines was generally higher among female students (p = 0.001). The use of OTC medication during exams was more among high school and university students. Gender, age and educational institution were found significantly affecting the use of OTC medicines during exams.

The descriptive, cross-sectional study was conducted at Istanbul University, Turkey, and comprised students preparing for exams in two private courses for the 2010-11 academic year. Data was collected via an original questionnaire and the Test Anxiety Inventory. SPSS 20 was used for statistical analyses. Of the 1250 students who qualified for the study, the final sample size was 376 (30%). Of them, 210 (55.9%) were females, and 154 (41%) were 18 years old. Students' mean Test Anxiety Inventory scores were 39.44±11.34. Female students' overall test anxiety scores and mean emotionality subscale score were significantly higher than those of their male counterparts. Students whose mothers had an educational attainment between primary school n=170 (45.2%) and a high school diploma n=184 (48.9%), as well as those with four or more siblings n=49 (15%), had significantly higher mean overall Test Anxiety Inventory scores. Among other things, test anxiety is influenced by maternal educational level, type of high school, number of exams, and number of siblings. Preparing a relaxed study environment for students, providing the family monetary or social support, and encouraging participation in social activities are recommendedto decreajb anxiety in students preparing for university exams.

    Computer-based testing (CBT) has made progress in health sciences education. In 2015, the authors led implementation of a CBT system (ExamSoft) at a dental school in the U.S. Guided by the Technology Acceptance Model (TAM), the purposes of this study were to (a) examine dental students' acceptance of ExamSoft; (b) understand factors impacting acceptance; and (c) evaluate the impact of ExamSoft on students' learning and exam performance. Survey and focus group data revealed that ExamSoft was well accepted by students as a testing tool and acknowledged by most for its potential to support learning. Regression analyses showed that perceived ease of use and perceived usefulness of ExamSoft significantly predicted student acceptance. Prior CBT experience and computer skills did not significantly predict acceptance of ExamSoft. Students reported that ExamSoft promoted learning in the first program year, primarily through timely and rich feedback on examination performance. t-Tests yielded mixed results on whether students performed better on computerized or paper examinations. The study contributes to the literature on CBT and the application of the TAM model in health sciences education. Findings also suggest ways in which health sciences institutions can implement CBT to maximize its potential as an assessment and learning tool.

    Many women who receive medical care in residency training clinics refuse to allow male residents to perform their pelvic exams. This study was conducted to identify which women were most likely to refuse and to learn their reasons for refusing. From January to March 1997, a questionnaire was given to all women entering a Tri-County Health office and a Planned Parenthood clinic, both in the Denver, Colorado, metropolitan area, who consented to participate in the study. Data from the questionnaire were analyzed using a statistical software package. A total of 1,437 women entered the clinics during the study period. Of these patients, 1,078 consented to complete the questionnaire. Seven of these 1,078 women did not complete the questionnaire. Women who did not know the training level of the resident performing the pelvic exam were more likely to refuse than were women who knew the training level of the resident (p =.001), but many women preferred a female physician regardless of the physician's training level. Fifty-eight percent said they would allow a male resident to observe a female attending physician perform the exam, compared with 36% who said they would allow a male resident to observe if the attending physician was a man. Common statements from those who would refuse were: "I am just more comfortable with a female," "Women do not want men to examine their private body parts," and "Women explain things better." A woman's knowledge of the resident's training level correlates with her willingness to have a pelvic exam performed by a male resident. Women who said they would refuse a pelvic exam performed by a male resident gave specific reasons for their decision.

    2015-01-01

    Adequate, efficient preparation for the ABR Diagnostic and Nuclear Medical Physics exams is key to successfully obtain ABR professional certification. Each part of the ABR exam presents its own challenges: Part I: Determine the scope of basic medical physics study material, efficiently review this material, and solve related written questions/problems. Part II: Understand imaging principles, modalities, and systems, including image acquisition, processing, and display. Understand the relationship between imaging techniques, image quality, patient dose and safety, and solve related written questions/problems. Part III: Gain crucial, practical, clinical medical physics experience. Effectively communicate and explain the practice, performance, and significance of all aspects of clinical medical physics. All three parts of the ABR exam require specific skill sets and preparation: mastery of basic physics and imaging principles; written problem solving often involving rapid calculation; responding clearly and succinctly to oral questions about the practice, methods, and significance of clinical medical physics. This symposium focuses on the preparation and skill sets necessary for each part of the ABR exam. Although there is some overlap, the nuclear exam covers a different body of knowledge than the diagnostic exam. A separate speaker will address those aspects that are unique to the nuclear exam. Medical physicists who have recently completed each of part of the ABR exam will share their experiences, insights, and preparation methods to help attendees best prepare for the challenges of each part of the ABR exam. In accordance with ABR exam security policy, no recalls or exam questions will be discussed.

  6. Anoftalmia bilateral como defeito congênito isolado: uma abordagem etiológica e psicossocial

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available A anoftalmia é uma condição oftalmológica rara, caracterizada pela ausência de um ou ambos os olhos, de etiologia não elucidada, podendo ser congênita, adquirida ou associada a outras síndromes sistêmicas. Quanto à etiologia, já foram descritas na literatura aberrações cromossômicas, mutações genéticas e fatores ambientais como responsáveis pelo surgimento da anomalia. Não existe consenso sobre a real incidência da anoftalmia, devido à escassez em dados oficiais, principalmente no Brasil. Neste estudo relata-se um caso de uma paciente do sexo feminino que apresenta anoftalmia bilateral congênita, sem outras anormalidades. Foram utilizados dados compilados do prontuário médico hospitalar, exames laboratoriais e de imagem realizados durante a internação, bem como exames solicitados no acompanhamento clínico pós-alta e um questionário aplicado aos responsáveis legais pela paciente. Os fatores genéticos e não genéticos envolvidos no desenvolvimento de anomalias, assim como as complicações estéticas e psicossociais advindas da anoftalmia foram discutidos. Conclui-se que o fator idade pode estar relacionado ao aparecimento da anoftalmia e que a maior divulgação desta rara anomalia congênita propiciará aos profissionais da saúde, especialmente aos oftalmologistas, conhecimentos adicionais para lidar com os aspectos físicos, humanísticos e sociais envolvidos no atendimento do paciente e de seus familiares, minimizando a gravidade e abrangência dos seus efeitos.

    2015-12-01

    For Virtual Patient-based exams, several scoring and grading methods have been proposed, but none have yet been validated. The aim of this study was to evaluate a new scoring and grading model for VP-based exams in postgraduate paediatric nurse education. The same student group of 19 students performed a VP-based exam in three consecutive courses. When using the scoring and grading assessment model, which contains a deduction system for unnecessary or unwanted actions, a progression was found in the three courses: 53% of the students passed the first exam, 63% the second and 84% passed the final exam. The most common reason for deduction of points was due to students asking too many interview questions or ordering too many laboratory tests. The results showed that the new scoring model made it possible to judge the students' clinical reasoning process as well as their progress. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2008-04-01

    Full Text Available O líquido cefalorraquidiano (LCR é um fluido biológico que está em íntima relação com o sistema nervoso central (SNC. Por isso, o exame do LCR constitui um método de grande valia para o diagnóstico e o acompanhamento de diversas afecções neurológicas. Entretanto, existem poucos estudos sobre a estabilidade de seus analitos durante a etapa pré-analítica. OBJETIVO: Identificar dados existentes sobre a influência da temperatura e do tempo de estocagem, dos ciclos de congelamento/descongelamento e pré-tratamentos (centrifugação, desnaturação, adição de soro na estabilidade dos analitos do LCR. MÉTODO: Foi realizada uma revisão sistemática de artigos da literatura, usando palavras-chave da língua inglesa como storage, cerebrospinal fluid, CSF, stability, temperature e period, com base nos serviços de dados de PubMed, Highwire Press, Lilacs e Amazonas Library, os quais permitem a pesquisa bibliográfica de citações e artigos científicos. RESULTADO: A busca encontrou nove artigos, resultado da escassez de trabalhos sobre o assunto. Os analitos do LCR estudados incluíram células (número e morfologia, proteínas totais, glicose, lactato, aminoácidos, creatina, creatinina, biomarcadores e enzimas. As metodologias se basearam em microscopia óptica, ensaio imunossorvente ligado à enzima (ELISA, Imunoblot/SDS-PAGE e fotometria. CONCLUSÃO: A revisão da literatura confirma que a estabilidade da amostra de LCR sofre influência da temperatura, do tempo de estocagem e das condições de preparo pré-analítico. Os achados desta revisão sistemática podem contribuir para a ampliação dos conhecimentos no exame do LCR, assim como o melhor entendimento sobre a estabilidade da amostra.The cerebrospinal fluid (CSF is a biological fluid that is in close relation with the central nervous system (CNS.

    The amendment of the Medical Licensing Act (ÄAppO) in Germany in 2002 led to the introduction of graded assessments in the clinical part of medical studies. This, in turn, lent new weight to the importance of written tests, even though the minimum requirements for exam quality are sometimes difficult to reach. Introducing exam quality as a criterion for the award of performance-based allocation of funds is expected to steer the attention of faculty members towards more quality and perpetuate higher standards. However, at present there is a lack of suitable algorithms for calculating exam quality. In the spring of 2014, the students' dean commissioned the "core group" for curricular improvement at the University Medical Center in Rostock to revise the criteria for the allocation of performance-based funds for teaching. In a first approach, we developed an algorithm that was based on the results of the most common type of exam in medical education, multiple choice tests. It included item difficulty and discrimination, reliability as well as the distribution of grades achieved. This algorithm quantitatively describes exam quality of multiple choice exams. However, it can also be applied to exams involving short assay questions and the OSCE. It thus allows for the quantitation of exam quality in the various subjects and - in analogy to impact factors and third party grants - a ranking among faculty. Our algorithm can be applied to all test formats in which item difficulty, the discriminatory power of the individual items, reliability of the exam and the distribution of grades are measured. Even though the content validity of an exam is not considered here, we believe that our algorithm is suitable as a general basis for performance-based allocation of funds.

    Nawfel, RD; Young, G

    2016-01-01

    Purpose: To measure patient skin dose from CT angiography (CTA) and CT exams of the head, and determine if patients having multiple exams could receive cumulative doses that approach or exceed deterministic thresholds. Methods: This study was HIPAA compliant and conducted with IRB approval. Patient skin doses were measured over a 4 month period using nanoDot OSL dosimeters placed on the head of 52 patients for two CT scanners. On each scanner, 26 patients received CT exams (scanner 1: 10 females, 16 males, mean age 64.2 years; scanner 2: 18 females, 8 males, mean age 61.2 years). CT exam dose metrics, CTDIvol and dose-length product (DLP) were recorded for each exam. Additionally, skin dose was measured on an acrylic skull phantom in each scanner and on a neuro-interventional imaging system using clinical protocols. Measured dose data was used to estimate peak skin dose (PSD) for 4 patients receiving multiple exams including CTA, head CT, and cerebral angiography. Results: For scanner 1, the mean PSD for CTA exams (98.9 ± 5.3 mGy) and for routine head CT exams (39.2 ± 3.7 mGy) agreed reasonably well with the PSD measured on the phantom, 105.4 mGy and 40.0 mGy, respectively. Similarly for scanner 2, the mean PSD for CTA exams (98.8 ± 7.4 mGy) and for routine head CT exams (42.9 ± 9.4 mGy) compared well with phantom measurements, 95.2 mGy and 37.6 mGy, respectively. In addition, the mean PSD was comparable between scanners for corresponding patient exams, CTA and routine head CT respectively. PSD estimates ranged from 1.9 – 4.5 Gy among 4 patients receiving multiple exams. Conclusion: Patients having several exams including both CTA and routine head CT may receive cumulative doses approaching or exceeding the threshold for single dose deterministic effects.

    Purpose: To measure patient skin dose from CT angiography (CTA) and CT exams of the head, and determine if patients having multiple exams could receive cumulative doses that approach or exceed deterministic thresholds. Methods: This study was HIPAA compliant and conducted with IRB approval. Patient skin doses were measured over a 4 month period using nanoDot OSL dosimeters placed on the head of 52 patients for two CT scanners. On each scanner, 26 patients received CT exams (scanner 1: 10 females, 16 males, mean age 64.2 years; scanner 2: 18 females, 8 males, mean age 61.2 years). CT exam dose metrics, CTDIvol and dose-length product (DLP) were recorded for each exam.

    Full Text Available Abstract Background Intercalated BScs (iBScs are an optional part of the medical school curriculum in many Universities. Does undertaking an iBSc influence subsequent student performance? Previous studies addressing this question have been flawed by iBSc students being highly selected. This study looks at data from medical students where there is a compulsory iBSc for non-graduates. Our aim was to see whether there was any difference in performance between students who took an iBSc before or after their third year (first clinical year exams. Methods A multivariable analysis was performed to compare the third year results of students at one London medical school who had or had not completed their iBSc by the start of this year (n = 276. A general linear model was applied to adjust for differences between the two groups in terms of potential confounders (age, sex, nationality and baseline performance. Results The results of third year summative exams for 276 students were analysed (184 students with an iBSc and 92 without. Unadjusted analysis showed students who took an iBSc before their third year achieved significantly higher end of year marks than those who did not with a mean score difference of 4.4 (0.9 to 7.9 95% CI, p = 0.01. (overall mean score 238.4 "completed iBSc" students versus 234.0 "not completed", range 145.2 - 272.3 out of 300. There was however a significant difference between the two groups in their prior second year exam marks with those choosing to intercalate before their third year having higher marks. Adjusting for this, the difference in overall exam scores was no longer significant with a mean score difference of 1.4 (-4.9 to +7.7 95% CI, p = 0.66. (overall mean score 238.0 " completed iBSc" students versus 236.5 "not completed". Conclusions Once possible confounders are controlled for (age, sex, previous academic performance undertaking an iBSc does not influence third year exam results. One explanation for this

    The objective of this paper is to estimate the values of doses, which are absorbed dose to the lens and thyroid in a dental X-ray. Thermoluminescence dosimeters were used, once they provide a reading of quality and effectiveness. This study was based on dental exams conducted in patients in order to estimate the dose that disperses to the lens of the eye and for the thyroid during an intraoral exam. Data collection took place in two institutions, one governmental, which had the device SELETRONIC 70X and other particular. This study showed that there is a considerable variation between the appliances. Using the appliance DABI 1070, there was a greater absorption of radiation in the right eye (values greater than 5 mGy) and a lower dose in the thyroid, and the Seletronic 70X presented an incidence of higher dose deposited in the skin and in other points there was a balance in the values. In the appliance SELETRONIC 70X, there was again a greater absorption of radiation in the right eye and a lower setting in the thyroid. The excessive dose, besides does not favor at all for the quality of radiograph, represents a risk for the patient who absorbs unnecessary and harmful radiation to the body.

Se define la neolengua, se ofrecen similitudes de la misma en el lenguaje publicitario en España, se trazan sus orígenes y se apuntan algunos antecedentes en la historia de la literatura inglesa, al tiempo que se ilustran ejemplos de variantes contemporáneas de la misma bajo la denominación de «nukespeak», especialmente abundantes en el discurso de los conflictos bélicos. La lengua inglesa está indisociablemente unida a complejos factores de orden económico, tecnológico y cultural que afectan a su misma morfología. Por otra parte, la presencia ubicua de la lengua inglesa, como idioma global, opera sobre las estructuras de sentimiento, pensamiento y acción de los ciudadanos en todo el mundo. Para los profesionales de la enseñanza del idioma inglés, ello comporta la obligación de discernir y resistir sus efectos potencialmente perversos al tiempo que siguen promoviendo sus valiosos beneficios culturales.ABSTRACT: Contemporary uses and abuses of the English language are examined in the context of complex issues and globalization trends. The term «newspeak» is defined, similitudes of it are found today in the language of advertising in Spain, its origins are traced back and antecedents are located in the history of English literature, while the presence of new modalities of the Orwellian reductionist language, such as «nukespeak», is illustrated within the language of warfare. The English language is inextricably bound up with economical, technological and cultural factors which affect its very morphology just as much as the pervasive influence of English as a global language affects the structures of feeling, thought and action of citizens all over the world, which poses an obligation on the part of EFL teachers to discern and resist its ill effects while they promote its still highly valuable cultural

    2017-01-01

    We introduce the notion of privacy-preserving verifiability for security protocols. It holds when a protocol admits a verifiability test that does not reveal, to the verifier that runs it, more pieces of information about the protocol’s execution than those required to run the test. Our definition...... of privacy-preserving verifiability is general and applies to cryptographic protocols as well as to human security protocols. In this paper we exemplify it in the domain of e-exams. We prove that the notion is meaningful by studying an existing exam protocol that is verifiable but whose verifiability tests...... are not privacy-preserving. We prove that the notion is applicable: we review the protocol using functional encryption so that it admits a verifiability test that preserves privacy according to our definition. We analyse, in ProVerif, that the verifiability holds despite malicious parties and that the new...

    Question Answering in Exams is typical question answering task that aims to test how accurately the model could answer the questions in exams. In this paper, we use general deep learning model to solve the multi-choice question answering task. Our approach is to build distributed word embedding of question and answers instead of manually extracting features or linguistic tools, meanwhile, for improving the accuracy, the external corpus is introduced. The framework uses a two layers LSTM with attention which get a significant result. By contrast, we introduce the simple long short-term memory (QA-LSTM) model and QA-LSTM-CNN model and QA-LSTM with attention model as the reference. Experiment demonstrate superior performance of two layers LSTM with attention compared to other models in question answering task.

    There were investigated changes in indices of the activity of regulatory mechanisms of heart rhythm in student under exam stress conditions and the possibility of their correction with aid of aromatherapy. The examination stress was established to be accompanied by pronounced shifts of integral and spectral indices of heart rhythm in students, indicating to the activation of the sympathetic circuit of Autonomic Nervous System in conditions of examination stress. A positive, relaxation impact of the essential oil of orange on the investigated indices was also recorded. The latter is expressed by weakly pronounced changes or lack of them in data of integral and spectral heart rate indices in students from the experimental group, that indicates to the stabilizing effect of used ethereal oil on the psycho-physiological state of students in conditions of exam stress

    Predoctoral dental psychomotor examinations are known to generate high levels of stress among dental students, which may compromise their academic performance. At one U.S. dental school, all 93 first-year dental students were invited to attend a series of three workshop sessions prior to enrollment in their initial operative dentistry course. The workshops were developed to facilitate academic transition from the dental anatomy course to the operative dentistry course; provide early exposure to materials, instruments, and laboratory techniques; support the early development of psychomotor and self-assessment skills; and lessen students' stress and anxiety levels regarding psychomotor examinations. The aim of this study was to assess the impact of the workshops on the students' academic performance and self-reported stress and preparedness. All students who attended the workshop sessions and all who did not were asked to complete a pre-exam survey (immediately preceding the exam) and a post-exam survey (immediately after the exam) on the day of their first operative dentistry psychomotor exam. Of the 93 students, 21 attended one, 34 attended two, and 25 attended three workshop sessions, while 13 students did not attend any. Response rates for the pre- and post-exam surveys were 100% and 98.9%, respectively. Students who attended all three workshop sessions reported being significantly less stressed about taking the exam than the other groups. The mean exam grade of students who attended the workshop sessions was significantly higher than that of students who did not attend the sessions. These findings support the development and implementation of preparatory workshops to improve academic performance and decrease the stress levels of dental students prior to the first operative dentistry psychomotor exam.

    The Plastic Surgery In-Service Training Exam is written by the American Society of Plastic Surgeons. Examinees reasonably infer that tested material reflects the Society's vision for the core curriculum in plastic surgery. The purpose of this study was to determine the levels of evidence on which credited answers to the examination questions are based. Two recent Plastic Surgery In-Service Training Exams (2014 and 2015) were analyzed. Questions were categorized using a taxonomy model. Recommended journal article references for Level III (decision-making) questions were assigned a level of evidence. Exam sections were analyzed for differences in question taxonomy distribution and level of evidence. To look for studies with higher levels of evidence, a PubMed search was conducted for a random sample of 10 questions from each section. One hundred three Level I (25.8 percent), 138 Level II (34.5 percent), and 159 Level III (39.8 percent) questions were analyzed (p < 0.001). The hand and lower extremity section had the highest percentage of Level III questions (50.0 percent; p = 0.005). Journal articles had a mean level of evidence of 3.9 ± 0.7. The number of articles with a low level of evidence (IV and V) (p = 0.624) and the percentage of questions supported by articles with a high level of evidence (I and II) (p = 0.406) did not vary by section. The PubMed search revealed no instances of a higher level of evidence than the recommended reading list. A significant percentage of Plastic Surgery In-Service Training Exam questions test clinical management, but most are supported with a low level of evidence. Although that is consistent with low level of evidence of plastic surgery literature, educators should recognize the potential for biases of question writers.

    2015-01-01

    Purpose: As the landscape of learning and testing shifts toward a computer-based environment, a replacement for paper-based methods of studying is desirable. Using Microsoft Excel, a study tool was developed that allows the user to populate multiple-choice questions and then generate an interactive quiz session to answer them. Methods: The code for the tool was written using Microsoft Excel Visual Basic for Applications with the intent that this tool could be implemented by any institution with Excel. The base tool is a template with a setup macro, which builds out the structure based on user’s input. Once the framework is built, the user can input sets of multiple-choice questions, answer choices, and even add figures. The tool can be run in random-question or sequential-question mode for single or multiple courses of study. The interactive session allows the user to select answer choices and immediate feedback is provided. Once the user is finished studying, the tool records the day’s progress by reporting progress statistics useful for trending. Results: Six doctoral students at UTHSCSA have used this tool for the past two months to study for their qualifying exam, which is similar in format and content to the American Board of Radiology (ABR) Therapeutic Part II exam. The students collaborated to create a repository of questions, met weekly to go over these questions, and then used the tool to prepare for their exam. Conclusion: The study tool has provided an effective and efficient way for students to collaborate and be held accountable for exam preparation. The ease of use and familiarity of Excel are important factors for the tool’s use. There are software packages to create similar question banks, but this study tool has no additional cost for those that already have Excel. The study tool will be made openly available

    While the number of international students has increased over the last decade, such students face diverse challenges due to language and cultural barriers. International medical students suffer from personal distress and a lack of support. Their performance is significantly lower than non-international peers in clinical examinations. We investigated whether international students benefit from a peer-led exam preparation course. An exam preparation course was designed, and relevant learning objectives were defined. Two evaluations were undertaken: Using a qualitative approach, tutees (N = 10) were asked for their thoughts and comments in a semi-structured interview at the end of the semester. From a quantitative perspective, all participants (N = 22) were asked to complete questionnaires at the end of each course session. International students reported a range of significant benefits from the course as they prepared for upcoming exams. They benefited from technical and didactic, as well as social learning experiences. They also considered aspects of the tutorial's framework helpful. Social and cognitive congruence seem to be the key factors to success within international medical students' education. If tutors have a migration background, they can operate as authentic role models. Furthermore, because they are still students themselves, they can offer support using relevant and understandable language.

    One of the challenges of multidetector computerized tomography is to minimize the risk of ionizing radiation using optimized protocols since higher doses are necessary to obtain high image quality. It was also noted that, due to the geometry in image acquisition using MDCT becomes necessary to estimate dose values consistent with the hypothesis clinically and with the specificities of the tomographic equipment. The aim of this study was to estimate the doses in abdomen exams from the data recorded on the MDCT console and dimensions obtained from DICOM images of patients undergoing different clinical protocols. Were collected, from the image DICOM of 101 exams, values of the dose length product (DLP) provided by Philips Health Care - Brilliance 64 equipment console, in order to relate them with the dose values obtained by means of thermoluminescent dosimeters ( TLD ) of CasSo 4 :Mn placed on the surface of a cylindrical simulator abdomen acrylic manufactured under the technical - operational conditions for a typical abdomen exam. From the data obtained, it was possible to find a factor of 1.16 ( 5 % ) indicating that the DLP values Brilliance 64 console underestimate the doses and this should be used with correction factor to estimate the total dose of the patient.

    The aim of this work was to estimate the incident air kerma of lateral (LAT) and anterior-posterior (AP) together with posterior-anterior (PA) projection chest X-ray exams in one of the largest pediatric hospitals in Brazil. Dosimetric results are accompanied with the detailed analysis of patient characteristics and radiographer strategy. The exams of 225 (119 male and 106 female) patients were studied and 389 X-ray exams (200 AP/PA projections and 189 LAT projections) of pediatric patients were acquired. Patient thickness can be restored from age, height or weight with the uncertainty of ∼20-30%. Very slight correlation between the patient dose and thickness was observed with the difference in dose for patients of the same thickness reaching 4 times. By standardization of radiological protocols, it should be possible to keep dose within the intervals 50-100 μGy for LAT projection and 40-80 μGy for AP/PA projection. The dose values are lower than those recommended by major European guidelines to good practice. (author)

    This docimological analysis is based on computer treatment of the results of the anatomy exam for the two sessions of July (159 candidates) and October (56 candidates) of the identification questions, discrimination questions, coupling (paining), grouping, association and diagram labelling. The results were appraised following certain parameters: the gross score revealed a rather low average score for the whole class (14.57 and 9.57 over 30): the low success rate in July and the average figure of October indicate, in general, either the difficulty of the questions for the students or a bad reception of the message; the bad discrimination index, since only 21% of the questions are of the discriminatory type. This finding pointed to a revision of 50 of the 68 questions of July and 53 of the 68 questions of October. On the whole, only 15 questions, over the two sessions, could have been kept unchanged for an eventual bank (stock of data): The correlation coefficient has showed a significant relation between success in the anatomy subject and success in the PCEM2 exam. This work has showed the possibilities that computers may offer in the teaching of anatomy and the evaluation of students. Besides, it emphasizes the importance of the anatomy grade in the PCEM2 exam. Finally, the mode evaluation used help exploring the various levels of the cognitive areas (memorization, interpretation of data, problem-solving) and to build up a bank of anatomy questions.

    Full Text Available The article presents the methodology and results of a survey on equating the lower secondary school examinations from 2002–2010. The survey was carried out by the Student Performance Analysis Unit at the Educational Research Institute. More than 10 000 students were selected for the equating study and information about more than 500 items was used. IRT models were used for equating exams, the results were presented on a latent variable scale and the observed score scale. Using this procedure, it was possible to isolate random difficulty variation between exam papers from specific years and present changes in ability level of students taking the exam. Based on the results, the level of humanities abilities of lower secondary school leavers was stable, whilst maths and science demonstrated a downward trend. Equating was validated by comparison with the results of the international PISA survey. Results for the arts and humanities were consistent with the PISA results for reading literacy. Maths and science, as compared with the PISA survey maths section demonstrated greater divergence.

    2005-01-01

    Purpose: Our aim was to evaluate how many medical requests for US, CT and MR outpatients exams are inadequate. Materials and methods: We evaluated three series of consecutive requests for outpatients exams, distinguishing firstly the adequate from the inadequate requests. The inadequate requests were classified as: (A) absence of real indication; (B) lacking or vague clinical query; (C) absence of important information on patient's status. US requests concerned 282 patients for 300 body segments, as follows: neck (n=50); upper abdomen (n=95); lower abdomen (n=12); upper and lower abdomen (n=84); musculoskeletal (n=32); other body segments (n=27). CT requests concerned 280 patients for 300 body segments, as follows: chest (n=67); abdomen (n=77); musculoskeletal (n=94); other body segments (n=62). MR musculoskeletal requests concerned 138 patients for 150 body segments, as follows: knee (n=87); ankle (n=13); shoulder (n=28); other body segments (n=22). Results: A total of 228/300 US requests (76%) were inadequate, ranging from 66% (musculoskeletal) to 86% (neck) classified as: A, 21/228 (9%); B, 130/228 (57%); C, 77/228 (34%). A total of 231/300 (77%) body CT request were inadequate, ranging from 72% (chest) to 86% (musculoskeletal), classified as: A, 22/231 (10%); B, 88/231 (38%); C, 121/231 (52%).

    Craniofacial microsomia is a common congenital condition for which children receive longitudinal, multidisciplinary team care. However, little is known about the etiology of craniofacial microsomia and few outcome studies have been published. In order to facilitate large, multicenter studies in craniofacial microsomia, we assessed the reliability of phenotypic classification based on photographs by comparison with direct physical examination. Thirty-nine children with craniofacial microsomia underwent a physical examination and photographs according to a standardized protocol. Three clinicians completed ratings during the physical examination and, at least a month later, using respective photographs for each participant. We used descriptive statistics for participant characteristics and intraclass correlation coefficients (ICCs) to assess reliability. The agreement between ratings on photographs and physical exam was greater than 80 % for all 15 categories included in the analysis. The ICC estimates were higher than 0.6 for most features. Features with the highest ICC included: presence of epibulbar dermoids, ear abnormalities, and colobomas (ICC 0.85, 0.81, and 0.80, respectively). Orbital size, presence of pits, tongue abnormalities, and strabismus had the lowest ICC, values (0.17 or less). There was not a strong tendency for either type of rating, physical exam or photograph, to be more likely to designate a feature as abnormal. The agreement between photographs and physical exam regarding the presence of a prior surgery was greater than 90 % for most features. Our results suggest that categorization of facial phenotype in children with CFM based on photographs is reliable relative to physical examination for most facial features.

    Cognitive scales are used frequently in geriatric research and practice. These instruments are constructed with underlying assumptions that are a part of their validation process. A common measurement scale used in older adults is the Folstein Mini Mental State Exam (MMSE). The MMSE was designed to screen for cognitive impairment and is used often in geriatric research. This paper has three aims. Aim one was to explore four potential threats to validity in the use of the MMSE: (1) administering the exam without meeting the underlying assumptions, (2) not reporting that the underlying assumptions were assessed prior to test administration, (3) use of variable and inconsistent cut-off scores for the determination of presence of cognitive impairment, and (4) failure to adjust the scores based on the demographic characteristics of the tested subject. Aim two was to conduct a literature search to determine if the assumptions of (1) education level assessment, (2) sensory assessment, and (3) language fluency were being met and clearly reported in published research using the MMSE. Aim three was to provide recommendations to minimalize threats to validity in research studies that use cognitive scales, such as the MMSE. We found inconsistencies in published work in reporting whether or not subjects meet the assumptions that underlie a reliable and valid MMSE score. These inconsistencies can pose threats to the reliability of exam results. Fourteen of the 50 studies reviewed reported inclusion of all three of these assumptions. Inconsistencies in reporting the inclusion of the underlying assumptions for a reliable score could mean that subjects were not appropriate to be tested by use of the MMSE or that an appropriate test administration of the MMSE was not clearly reported. Thus, the research literature could have threats to both validity and reliability based on misuse of or improper reported use of the MMSE. Six recommendations are provided to minimalize these threats

  8. The development and performance of the EXAM detector to search for extragalactic antimatter

    The design and development of a practical balloon borne instrument capable of detecting heavy (Z approximately equal to -26) antimatter in the cosmic rays are described. Emphasis is placed on describing the essential physics of the EXAM (extragalactic antimatter) instrument's individual detectors that make such a detection possible. In particular, it is shown that the responses from a plastic scintillator, a Cerenkov radiation detector, dielectric track detectors, and proportional drift tube arrays can be used to uniquely determine the speed, charge magnitude, and charge sign of a cosmic ray nucleus. This novel nonmagnetic detection scheme permits the construction of a relatively light weight (approximately 2,000 kg) detector with a large collecting power (approximately 10 sq m sr). The profound cosmological and elementary particle physics implications of the detection of just a single heavy antimatter nucleus are discussed in chapter one, along with arguments that imply that such a detected antinucleus must necessarily be extragalactic in origin. Chapters two through six describe the response of EXAM's individual detectors to the passage of heavily ionizing charged particles. Chapter seven is an overview of the mechanical construction of the entire instrument. Details of the measurement of the light collection efficiency of EXAM's Cerenkov detector and primary scintillator using sea-level muons and how this will be used to assist in the flight data analysis are contained in chapter eight. This chapter also includes a description of the instrument's electronic configuration and its data acquisition system. Finally, there are two appendices summarizing some important mechanical stress calculations that were required to actually build the instrument

    Full Text Available El artículo examina el concepto de leyenda como intangible territorial en diversas escalas, desde la local a la regional o nacional, y su relación con la construcción de mitos étnicos y la emergencia de tradiciones translocales. Para ello, se revisan la metodología de los estudios corográficos y las nociones de ecotipo y de paisaje cultural, así como la etnografía de los territorios simbólicos a la luz de conceptos como el clásico «témenos» y modernos como el «mytho-moteur» (Abadal, 1958. Se aplican estudios de casos que evidencian cómo es el Imaginario, en interacción con factores geohistóricos del lugar, el que a menudo acota y perimetrea un territorio a través de cauces como la fabulación legendaria y los ritos paralitúgicos, como procesiones o peregrinaciones. La conclusión es que las leyendas y los arquetipos de origen étnico y genealógico reescriben tradiciones que crean identidades y se pueden proyectar en ámbitos diferentes de la vida política o recreativa, con perfiles igualmente diferentes.

  11. Development of a measure of student self-evaluation of physics exam performance

    Hagedorn, Eric Anthony

    The central purpose of this study was to provide preliminary evidence of the reliability and validity of the SEVSI - P (Self- evaluation scaled instrument - physics). This instrument, designed to measure student self-evaluation of physics exam performance, was developed in congruence with social cognitive theory. Self-evaluation in this study is defined to consist of two of the three subprocesses of self-regulation: self-observation and judgmental process. As such, the SEVSI - P consists of two subscales, one measuring the frequency and types of self-observations made during a physics exam and one measuring the frequency and types of judgmental comparisons made after an exam. Data from 621 completed surveys, voluntarily taken by first semester algebra/trigonometry based physics students at six Midwestern universities and one Southern university, were analyzed for reliability and factorial validity. Cronbach alphas of .71 and .83 for the self-observation and judgment subscales, respectively, indicate acceptable reliability for the instrument. Confirmatory factor analysis indicates the acceptability of the hypothesis that the data analyzed could have indeed been obtained from the proposed two factor model (self-observation and judgment). The results of this confirmatory factor analysis provide preliminary construct validity for this instrument. A number of theoretically related items were included on the SEVSI - P form to elicity information about the use of goals and pre-planned strategies, actions taken in response to previous poor performances, and emotional responses to performance. A correlational analysis of these items along with the self-observation and judgment subscale scores provided a limited degree of convergent validity for the two subscales. Analyses of variance were done to determine the presence of differences in scoring patterns based on gender or reported ethnic origin. These results indicate slightly higher judgment subscale scores for women and

    definitivo em parafina foi comparado com o exame de congelação. RESULTADOS: Dezesseis pacientes (64 % tiveram margens comprometidas e 9 (36 % livres. O diagnóstico definitivo na parafina foi concordante em todos os casos no diagnóstico do estado das margens. Em cinco casos foi diagnosticada invasão, sendo 1 caso de carcinoma microinvasivo. Entre os 20 casos restantes foram detectados 2 carcinomas microinvasivos adicionais após o exame em parafina. Desta forma o exame intra-operatório de congelação foi concordante com o exame definitivo em 23/25 casos (92 %. Dois casos de carcinoma microinvasivo foram diagnosticados como neoplasia intra-epitelial de alto grau no exame de congelação e apresentavam invasão estromal menor que 2 cm. CONCLUSÕES: O exame intra-operatório de congelação é capaz de predizer o estado das margens cirúrgicas em todos os casos de neoplasia intra-epitelial de alto grau assim como o diagnóstico de invasão franca. Nos casos de carcinoma microinvasivo este exame falha na detecção de invasão, entretanto é capaz de garantir margens livres de ressecção.

    To evaluate the impact of continued education provided by an external quality control laboratory on the indicators of internal quality control of cytopathology exams. The internal quality assurance indicators for cytopathology exams from 12 laboratories monitored by the External Quality Control Laboratory were evaluated. Overall, 185,194 exams were included, 98,133 of which referred to the period preceding implementation of a continued education program, while 87,061 referred to the period following this intervention. Data were obtained from the Cervical Cancer Database of the Brazilian National Health Service. Following implementation of the continued education program, the positivity index (PI) remained within recommended limits in four laboratories. In another four laboratories, the PI progressed from below the limits to within the recommended standards. In one laboratory, the PI remained low, in two laboratories, it remained very low, and in one, it increased from very low to low. The percentage of exams compatible with a high-grade squamous intraepithelial lesion (HSIL) remained within the recommended limits in five laboratories, while in three laboratories it progressed from below the recommended levels to >0.4% of the total number of satisfactory exams, and in four laboratories it remained below the standard limit. Both the percentage of atypical squamous cells of undetermined significance (ASC-US) in relation to abnormal exams, and the ratio between ASC-US and intraepithelial lesions remained within recommended levels in all the laboratories investigated. An improvement was found in the indicators represented by the positivity index and the percentage of exams compatible with a high-grade squamous intraepithelial lesion, showing that the role played by the external quality control laboratory in providing continued education contributed towards improving laboratory staff skills in detecting cervical cancer precursor lesions.

  17. Hair and stress: A pilot study of hair and cytokine balance alteration in healthy young women under major exam stress.

    Eva M J Peters

    Full Text Available Mouse models show that experimental stress mimicking prolonged life-stress exposure enhances neurogenic inflammation, induces adaptive immunity cytokine-imbalance characterized by a shift to Type 1 T-helper cell cytokines and increases apoptosis of epithelial cells. This affects hair growth in otherwise healthy animals. In this study, we investigate whether a prolonged naturalistic life-stress exposure affects cytokine balance and hair parameters in healthy humans. 33 (18 exam, 15 comparison female medical students with comparable sociobiological status were analyzed during a stressful final examination period, at three points in time (T 12 weeks apart. T1 was before start of the learning period, T2 between the three-day written exam and an oral examination, and T3 after a 12 week rest and recovery from the stress of the examination period. Assessments included: self-reported distress and coping strategies (Perceived Stress Questionnaire [PSQ], Trier Inventory for the Assessment of Chronic Stress [TICS], COPE, cytokines in supernatants of stimulated peripheral blood mononucleocytes (PBMCs, and trichogram (hair cycle and pigmentation analysis. Comparison between students participating in the final medical exam at T2 and non-exam students, revealed significantly higher stress perception in exam students. Time-wise comparison revealed that stress level, TH1/TH2 cytokine balance and hair parameters changed significantly from T1 to T2 in the exam group, but not the control. However, no group differences were found for cytokine balance or hair parameters at T2. The study concludes that in humans, naturalistic stress, as perceived during participation in a major medical exam, has the potential to shift the immune response to TH1 and transiently hamper hair growth, but these changes stay within a physiological range. Findings are instructive for patients suffering from hair loss in times of high stress. Replication in larger and more diverse sample

This paper analyzes the application of the concept in the AAA requests and justifications examinations using ionizing radiation within a large public hospital. Materials and methods: we collected and analyzed data between the years 2011 and 2012, concerning the number of exams performed with the use of radiation and their justifications. After, we sought to raise awareness of the clinical team through training on the risks and benefits of the various modalities of the radiology department and the need to justify the use of ionizing radiation on health. After the data were collected again of test requests for verification of the effectiveness of training. Results: the mean requests that need to be appropriate to the AAA in the last quarter of 2011 was 75 % lower than the average demands of the first quarter, matched against the last two months of 2012 increased by up to four times the number requests that require improvements in relation to the excellent results obtained in July 2012. Conclusion: it is shown in this paper the need of implementing this initiative AAA continuously added to the clinical staff awareness about the risk of the use of ionizing radiation, the appropriateness of the requests of these tests , as well as the control of this process in order to optimize use of ionizing radiation on health.

    Positron Emission Tomography (PET) associated with Computed Tomography (CT) allows the fusion of functional and anatomical images. When compared to other diagnostic techniques, PET-CT subjects patients to higher levels of radiation, because two modalities are used in a single exam. In this study, the doses absorbed in 19 patient organs from the tomographic scan were evaluated. Radiochromic films were correctly positioned in the Alderson anthropomorphic simulator, male version. For evaluation, two whole body scan protocols were compared. For evaluation, two whole body scan protocols were compared. An increase of up to 600% in the absorbed dose in the pituitary was observed when the protocols were compared, with the lowest observed increase of approximately 160% for the liver. It is concluded that the dose from CT in patients submitted to PET-CT scanning is higher in the protocol used for diagnosis. Considering the high cost of PET-CT exam, in many cases it is preferable that the CT examination is of diagnostic quality, and not only for anatomical mapping, an argument based on the Principle of Justification

    Putwain, David; Remedios, Richard

    2014-12-01

    Prior to high-stakes exams, teachers use persuasive messages that highlight to students the possible consequences of failure. Such messages are known as fear appeals. This study examined whether fear appeals relate to self- and non-self-determined motivation and academic performance. Data were collected in 3 waves. Self-report data pertaining to perceived fear appeals were collected in the first wave, self-report data pertaining to self-determined motivation were collected in the second wave, and exam scores were collected in the third wave. An increased frequency of fear appeals and the appraisal of fear appeals as threatening predicted lower self-determined motivation but were largely unrelated to non-self-determined motivation. An increased frequency of fear appeals and the appraisal of fear appeals as threatening predicted lower examination performance that was partly mediated by lower self-determined motivation. These findings support a position derived from self-worth theory that the negative consequences of fear appeals arise from their focus on avoiding failure rather than their focus on extrinsic consequences. We suggest that teachers and instructors need to be aware how seemingly motivational statements can unwittingly promote lower self-determined motivation.

    The Plastic Surgery In-Service Training Exam is a knowledge assessment tool widely used during plastic surgery training in the United States. This study analyzed literature supporting correct answer choices to determine highest yield sources, journal publication lag, and journal impact factors. Digital syllabi of 10 consecutive Plastic Surgery In-Service Training Exam administrations (2006 to 2015) were reviewed. The most-referenced articles, journals, and textbooks were determined. Mean journal impact factor and publication lag were calculated and differences were elucidated by section. Two thousand questions and 5386 references were analyzed. From 2006 to 2015, the percentage of journal citations increased, whereas textbook references decreased (p < 0.001). Plastic and Reconstructive Surgery was cited with greatest frequency (38.5 percent), followed by Clinics in Plastic Surgery (5.6 percent), Journal of Hand Surgery (American volume) (5.1 percent), and Annals of Plastic Surgery (3.8 percent). There was a trend toward less publication lag over the study period (p = 0.05), with a mean publication lag of 9.1 ± 9.0 years for all journal articles. Mean journal impact factor was 2.3 ± 4.3 and lowest for the hand and lower extremity section (1.7 ± 2.8; p < 0.001). The highest yield textbooks were elucidated by section. Plastic surgery faculty and residents may use these data to facilitate knowledge acquisition during residency.

    2014-01-01

    The management of image quality and radiation dose during pediatric CT scanning is dependent on how well one manages the radiographic techniques as a function of the type of exam, type of CT scanner, and patient size. The CT scanner's display of expected CT dose index volume (CTDI vol ) after the projection scan provides the operator with a powerful tool prior to the patient scan to identify and manage appropriate CT techniques, provided the department has established appropriate diagnostic reference levels (DRLs). This paper provides a step-by-step process that allows the development of DRLs as a function of type of exam, of actual patient size and of the individual radiation output of each CT scanner in a department. Abdomen, pelvis, thorax and head scans are addressed. Patient sizes from newborns to large adults are discussed. The method addresses every CT scanner regardless of vendor, model or vintage. We cover adjustments to techniques to manage the impact of iterative reconstruction and provide a method to handle all available voltages other than 120 kV. This level of management of CT techniques is necessary to properly monitor radiation dose and image quality during pediatric CT scans. (orig.)

MATERIAL E MÉTODO: Estudo retrospectivo dos pacientes com "hum" venoso realizado na UNIFESP-EPM de abril de 1997 a abril de 2003, analisando-se os parâmetros: idade de aparecimento, freqüência, lado acometido, presença de perda auditiva e tontura associadas, fatores de piora e melhora, resultados de audiometria, exame vestibular e tomografia computadorizada de ossos temporais, evolução e tratamento realizados. Foi utilizado um protocolo de exames e tratamento e os resultados foram comparados com os da literatura. RESULTADOS: O zumbido pulsátil ocorreu em 7,5% e o "hum" venoso em 3% do total de pacientes com zumbido, todos no sexo feminino, sem prevalência por época de aparecimento, acometendo mais a orelha esquerda. Em todos os pacientes houve melhora com tratamento clínico, não sendo necessária intervenção cirúrgica em nenhum caso. CONCLUSÃO: O "hum" venoso não é uma causa incomum de zumbido (39% dos zumbidos pulsáteis como citado na literatura. O tratamento deve ser realizado atuando-se sobre os fatores responsáveis pelo zumbido e decorrentes do mesmo. Em grande número de casos o mesmo desaparece espontaneamente, não necessitando de tratamento. O tratamento cirúrgico raramente é necessário, devendo ser reservado apenas aos casos em que não haja melhora com o tratamento clínico.

    Full Text Available Desde que en 1897 Benito Pérez Galdós defendiera como materia prima legítima de la literatura «la vida misma, de donde el artista saca las ficciones que nos instruyen y embelesan» (Pérez Galdós, 1990: 159, el realismo como instrumento de indagación y análisis de la sociedad no ha dejado de crecer y expandirse. Realismo crítico, como este de Galdós, que implica una ampliación del concepto chato de «realidad», incluyendo en ella «recuerdos, sueños, imaginación, locura, símbolos» para contribuir a la formación de un «realismo total» (Rodríguez Puértolas, 2000, II: 93, al que se une también la asimilación de enseñanzas esenciales como la que representa la narrativa de Cervantes: La novelística de Galdós hunde sus raíces en el mejor Cervantes, como puede verse en su peculiar sentido del humor y de la ironía, en la concepción perspectivista de la realidad y en tantas otras cosas, algunas de ellas en verdad fundamentales. Así el concepto de la Naturaleza y sus relaciones dialécticas con el ser humano; así el Amor como elemento vital y animador del orden cósmico, muy alejado del idealismo vulgar romántico (Ibid., 93.

    Full Text Available Background: Various educational approaches to learning have been proposed. It is, of course, of vital importance to study those that have resulted in effective educational achievements.Purpose: To assess the student's attitudes and performance in order to evaluate educational approaches and identify the variables leading to students gaining good marks.Methods: The subjects of the study were medical students at pathophysiology  phase. A multiple-choice questionnaire was prepared, the reliability and validity of which were confirmed. A paired-sample T­ test was used to compare and analyze  the student's  Basic Sciences Comprehensive  Exam scores in each discipline and their average score during the basic sciences course.Results: With respect to attitudes, the students highly valued the importance of teacher's methodology and mutual  respect, as an influential  factor in Learning. Furthermore, the majority  of the students relied heavily  on their textbooks  as the main source of information  and preferred to study at home, rather than any other places. Most of the students prefer to study in the morning. They believed that mid-term exams, quizzes, and active class participation do not have much effect on learning. However, it was of high importance to them to attend practical claSSfS (labs. With respect to performance, most of the students used lecture notes as the main references, and considered their home as a good place to study and  preferred to study in the morning,  but have  participated  in theoretical  and  practical classes regularly.Conclusion: Most successful students attributed their success to active class participation,  takingmid-term exams, quizzes, and using library. Having analyzed the data, we recommend the authorities to provide more methodology  workshops for teachers,  sufficient  number of textbooks,  expanding  or increasing the number of the reading rooms with essential equipment

    Recycling americium alone from the spent fuel is an important issue currently studied for the future nuclear cycle (Generation IV systems) as Am is one of the main contributors to the long-term radiotoxicity and heat power of final waste. The solvent extraction process called EXAm has been developed by the CEA to enable the recovery of Am alone from a PUREX raffinate (with U, Np and Pu already removed). A mixture of DMDOHEMA and HDEHP diluted in TPH is used as the solvent and the Am/Cm selectivity is improved using TEDGA as a selective complexing agent to maintain Cm and the heavier lanthanides in the acidic aqueous phase (HNO{sub 3} 5-6 M). Americium is then selectively stripped from the light lanthanides at low acidity (pH 2.5-3) with a poly-aminocarboxylic acid (DTPA). An additional step is necessary before Am recovery, in order to strip molybdenum which would otherwise be complexed by DTPA and contaminate the Am raffinate. In order to make the process and its associated future plant more compact, the objective is now to adapt the EXAm process to a concentrated raffinate. With a concentrated PUREX raffinate, the process operates under conditions close to saturation both for the solvent and complexing agent TEDGA during the Am extraction step. Consequently, some changes were needed to adapt the flowsheet to higher concentrations of cations. Before the test on a real PUREX raffinate in the CBP shielded line at ATALANTE (at the end of 2015), the EXAm flowsheet had to be consolidated and achievable target performances ensured. A series of experiments and tests was performed: on laboratory scale (batch experiments), to identify the good operating conditions and to simulate the main phenomena involved (2010-2014); first on an inactive surrogate feed solution at G1 facility (2011-2013), and then on a surrogate feed solution with trace amounts of americium and curium (spiked test) in the C17 shielded line at ATALANTE (2014).

    Full text: During the recent years, a policy for updating and installation of the X-ray equipment, specialized as well as conventional, have been carrying out, in Cuba. Conventional equipment has reached almost the whole primary level. Considering this situation, the quality control programs and clinical dosimetry have become even more important. Regarding the last one, an International Code of Practice for Dosimetry in Diagnostic Radiology had been published by the International Atomic Energy Agency in order to been used as a guide and to standardize the methodologies used to evaluate the patient exposure in radiodiagnostic. Taken into consideration the above reasons, an assessment of the aforementioned code of practice was done in order to choose the most feasible methodology to implement in the country. The evaluation was performed considering the lack of dosimetric equipment and medical physicists in this practice, in the interests of increasing the measurements scope to a large number of services as well as to standardize the methodology on a national scale. The present work shows the results obtained from the application of the new code of practice to conventional radiology exams in some medical institutions. Out of 3 on patients measurements methodologies described in the code of practice, the one of measurement of the incident air kerma was chosen. This methodology allow to the physicist to focus on the diagnostic equipment tests and to delegate the collection of the patient and exposure parameters data to the technicians, which make the increased of the patient and diagnostic departments sample, possible. The measurements were carried out in 2 hospital of the capital. The exams involved in the assessments were thorax PA, lumbar spine AP and lumbar spine LAT. In every diagnostic service, 25 patients were chosen on each projection. The weight and height average of the patient sample were 68 kg and 167 cm respectively. In the assessment were considered only

    Purpose: To determine exact electrical parameters (kV, mAs) a radiological technologist shall use taking account the exam and patient's structure, with guarantee of minimum dose and adequate quality image. Methods: A patient's absorbed dose equation was developed by means of Entrance Skin Dose (ESD), irradiated area and patient width for specific anatomy. ESD is calculated from a developed equation, where entrance surface air-KERMA and backscatter factor are included, with air-to-skin coefficient conversion. We developed specific Lambert-Beer attenuation equations derived from mass energy-absorption coefficients data for skin, fat, and muscle and bone as one tissue. Anatomy tissue thickness distribution at central X-ray location in anteroposterior incidence for hand and chest, was estimate by discounting constant skin and bone thickness from patient measured width, assuming the result as muscle and fat. A clinical research at a big hospital were executed when real parameters (kV, mAs, filtration, ripple) used by technologists were combined with the image quality and patient's data: anatomy width, height and weight. A correlation among the best images acquired and electrical parameters used were confronted with patient's data and dose estimation. The best combinations were used as gold standards. Results: For each anatomy, two equations were developed to calculate voltage (kV) and exposure (mAs) to reproduce and interpolate the gold standards. Patient is measured and data are input into equations, giving radiological technologists the right set of electrical parameters for that specific exam. Conclusion: This work indicates that radiological technologist can personalize the exact electrical parameters for each patient exam, instead of using standard values. It also guarantee that patients under or over-sized measures will receive the right dose for the best image. It will stop wrong empiric adjusts technologists do when examining a non
