    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.

  2. How chemistry students study for an exam: A phenomenographic analysis

    Science.gov (United States)

    Lowrey, Kirsten Andrea

    2002-08-01

    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.

  11. Do Resit Exams Promote Lower Investments of Study Time? Theory and Data from a Laboratory Study.

    Science.gov (United States)

    Nijenkamp, Rob; Nieuwenstein, Mark R; de Jong, Ritske; Lorist, Monicque M

    2016-01-01

    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.

  12. Comparative study of dose descriptor in pediatric computed tomography exams

    2014-01-01

    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

  14. The Effect of Enrollment in Middle School Challenge Courses on Advanced Placement Exams in Social Studies and Science

    Science.gov (United States)

    Glaude-Bolte, Katherine

    Educators seek to guide students through appropriate programs and courses that prepare them for future success, in more advanced coursework and in other challenges of life. Some middle schools offer Challenge, or honors, courses for students who have demonstrated high ability. High schools often offer Advanced Placement (AP) courses, which are taught at the college level. This study examined the correlation between enrollment in middle school Challenge courses and subsequent AP exam category scores in social studies and science in a suburban school district. The independent variables were the number of years of enrollment in middle school social studies or science Challenge courses. The dependent variables were the AP exam category scores in the eight social studies AP courses or the six science AP courses. The sample sizes were limited to the number of students who took an AP social studies or science exam and also attended the middle school of study. The null hypothesis was that there was no relationship between the two variables. This study included eight social studies AP courses and six science AP courses. A significant positive correlation was indicated in only two of the courses, U.S. Government and Comparative Government, supporting the claim that enrollment in middle school Challenge social studies was correlated with success, at least on these two AP exams. In the remaining 12 courses, there was not enough evidence to reject the null hypothesis. Therefore, enrollment in middle school Challenge science and social studies courses generally did not seem to correlate with AP exam category scores. Results of this study call into question the validity of the claim by the district that enrollment in Challenge courses helps prepare students for rigorous coursework in high school. Several factors, including student readiness, teacher training, familiarity with course content, and previous AP experience may contribute more to a student's AP exam category score

  16. Medication competency of nurses according to theoretical and drug calculation online exams: A descriptive correlational study.

    Science.gov (United States)

    Sneck, Sami; Saarnio, Reetta; Isola, Arja; Boigu, Risto

    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.

    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

    Huang, Sha; Deshpande, Aadya; Yeo, Sing-Chen; Lo, June C.; Chee, Michael W.L.; Gooley, Joshua J.

    2016-01-01

    Study Objectives: The ability to recall facts is improved when learning takes place at spaced intervals, or when sleep follows shortly after learning. However, many students cram for exams and trade sleep for other activities. The aim of this study was to examine the interaction of study spacing and time in bed (TIB) for sleep on vocabulary learning in adolescents. Methods: In the Need for Sleep Study, which used a parallel-group design, 56 adolescents aged 15–19 years were randomly assigned to a week of either 5 h or 9 h of TIB for sleep each night as part of a 14-day protocol conducted at a boarding school. During the sleep manipulation period, participants studied 40 Graduate Record Examination (GRE)-type English words using digital flashcards. Word pairs were presented over 4 consecutive days (spaced items), or all at once during single study sessions (massed items), with total study time kept constant across conditions. Recall performance was examined 0 h, 24 h, and 120 h after all items were studied. Results: For all retention intervals examined, recall of massed items was impaired by a greater amount in adolescents exposed to sleep restriction. In contrast, cued recall performance on spaced items was similar between sleep groups. Conclusions: Spaced learning conferred strong protection against the effects of sleep restriction on recall performance, whereas students who had insufficient sleep were more likely to forget items studied over short time intervals. These findings in adolescents demonstrate the importance of combining good study habits and good sleep habits to optimize learning outcomes.

  19. 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

    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.

    Martin Marietta Energy Systems, Inc., (Energy Systems) is committed to performing and documenting safety analyses for facilities it manages for the Department of Energy (DOE). Included are analyses of existing facilities done under the aegis of the Safety Analysis Report Upgrade Program, and analyses of new and modified facilities. A graded approach is used wherein the level of analysis and documentation for each facility is commensurate with the magnitude of the hazard(s), the complexity of the facility and the stage of the facility life cycle. Safety analysis reports (SARs) for hazard Category 1 and 2 facilities are usually detailed and extensive because these categories are associated with public health and safety risk. SARs for Category 3 are normally much less extensive because the risk to public health and safety is slight. At Energy Systems, safety studies are the name given to SARs for Category 3 (formerly open-quotes lowclose quotes) facilities. Safety studies are the appropriate instrument when on-site risks are limited to irreversible consequences to a few people, and off-site consequences are limited to reversible consequences to a few people.

    Purpose: To identify exam and patient parameters affecting the biological response to CT studies using in vivo and ex vivo blood samples. Methods: Blood samples were collected under IRB approval from 16 patients undergoing clinically-indicated CT exams. Blood was procured prior to, immediately after and 30minutes following irradiation. A sample of preexam blood was placed on the patient within the exam region for ex vivo analysis. Whole blood samples were fixed immediately following collection and stained for γH2AX to assess DNA damage response (DDR). Median fluorescence of treated samples was compared to non-irradiated control samples for each patient. Patients were characterized by observed biological kinetic response: (a) fast — phosphorylation increased by 2minutes and fell by 30minutes, (b) slow — phosphorylation continued to increase to 30minutes and (c) none — little change was observed or irradiated samples fell below controls. Total dose values were normalized to exam time for an averaged dose-rate in dose/sec for each exam. Relationships between patient biological responses and patient and exam parameters were investigated. Results: A clearer dose response at 30minutes is observed for young patients (<61yoa; R2>0.5) compared to old patients (>61yoa; R 2 <0.11). Fast responding patients were significantly younger than slow responding patients (p<0.05). Unlike in vivo samples, age did not significantly affect the patient response ex vivo. Additionally, fast responding patients received exams with significantly smaller dose-rate than slow responding patients (p<0.05). Conclusion: Age is a significant factor in the biological response suggesting that DDR may be more rapid in a younger population and slower as the population ages. Lack of an agerelated response ex vivo suggests a systemic response to radiation not present when irradiated outside the body. Dose-rate affects the biological response suggesting that patient response may be related to scan

    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.

    The aim of this study was to evaluate if differential learning in a preclinical dental course impacted the performance of dental students in a practical exam (preparation of a gold partial crown) immediately after the training session and 20 weeks later compared to conventional learning. This controlled study was performed in a preclinical course in operative dentistry at a dental school in Germany. Third-year students were trained in preparing gold partial crowns by using either the conventional learning (n=41) or the differential learning approach (n=32). The differential learning approach consisted of 20 movement exercises with a continuous change of movement execution during the learning session, while the conventional learning approach was mainly based on repetition, a methodological series of exercises, and correction of preparations during the training phase. Practical exams were performed immediately after the training session (T1) and 20 weeks later (T2, retention test). Preparations were rated by four independent and blinded examiners. At T1, no significant difference between the performance (exam passed) of the two groups was detected (conventional learning: 54.3%, differential learning: 68.0%). At T2, significantly more students passed the exam when trained by the differential learning approach (68.8%) than by the conventional learning approach (18.9%). Interrater reliability was moderate (Kappa: 0.57, T1) or substantial (Kappa: 0.67, T2), respectively. These results suggest that a differential learning approach can increase the manual skills of dental students.

  13. The Latin Matura exam

    Directory of Open Access Journals (Sweden)

    Tea Dolenc

    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.

    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.

  15. How Should I Study for the Exam? Self-Regulated Learning Strategies and Achievement in Introductory Biology.

    Sebesta, Amanda J; Bray Speth, Elena

    2017-01-01

    In college introductory science courses, students are challenged with mastering large amounts of disciplinary content while developing as autonomous and effective learners. Self-regulated learning (SRL) is the process of setting learning goals, monitoring progress toward them, and applying appropriate study strategies. SRL characterizes successful, "expert" learners, and develops with time and practice. In a large, undergraduate introductory biology course, we investigated: 1) what SRL strategies students reported using the most when studying for exams, 2) which strategies were associated with higher achievement and with grade improvement on exams, and 3) what study approaches students proposed to use for future exams. Higher-achieving students, and students whose exam grades improved in the first half of the semester, reported using specific cognitive and metacognitive strategies significantly more frequently than their lower-achieving peers. Lower-achieving students more frequently reported that they did not implement their planned strategies or, if they did, still did not improve their outcomes. These results suggest that many students entering introductory biology have limited knowledge of SRL strategies and/or limited ability to implement them, which can impact their achievement. Course-specific interventions that promote SRL development should be considered as integral pedagogical tools, aimed at fostering development of students' lifelong learning skills. © 2017 A. J.

O objetivo deste trabalho foi avaliar os níveis de ácido hipúrico encontrados em trabalhadores submetidos à monitorização biológica. Foi realizado um estudo retrospectivo com dados dos anos de 2002 a 2005, no qual foram analisados os resultados e a situação do empregado na oportunidade do exame (periódico, demissional e admissional. Os resultados indicam uma redução significativa nos níveis de ácido hipúrico em 2005. Exames periódicos obtiveram resultados superiores aos exames admissionais e demissionais, e não foi verificada diferença significativa nas proporções dos sujeitos agrupados de acordo com a situação funcional em cada um dos intervalos estabelecidos segundo o valor de referência e o índice biológico máximo permitido. Os níveis de ácido hipúrico detectados indicam um baixo de risco de exposição ao tolueno na população avaliada, provavelmente em decorrência da preocupação crescente com a implantação de medidas de higiene ocupacional.Hippuric acid is the primary metabolite of toluene, a solvent widely used in industrial processes with considerable toxic effects, a fact which justifies regularly monitoring individuals with occupational exposure to this solvent.

    Full Text Available Background Nowadays, one of the principal difficulties faced by educational systems worldwide is anxiety, a mental problem, which is evidently difficult to be endured by many students and leads to various types of mental and physical disorders or reduction of educational efficiency, and has gained attention of sociologists for its consequent psychological, social, and economical impacts. Objectives The current study aimed at predicting exam anxiety based on meta-cognitive beliefs and learning methods among high school students of Bandar Abbas. Methods The study population included 351 students (197 males and 154 females, who were selected randomly by the cluster approach and answered the research tools including Meta-Cognitive Beliefs Questionnaires (MCQ-30, Learning methods questionnaires of Marton and Saljoo (1996 and also test anxiety questionnaire of Alpert and Haber (1960. The study plan was correlative-descriptive. Pearson simple correlation coefficient, multi variable regression, and multi variable variance analysis were used to analyze the obtained data. Results The study results indicated that there was a positive significant relationship between meta-cognitive beliefs and exam anxiety, a negative significant relationship between profound learning and learning methods and exam anxiety, and a positive significant relationship between smattering learning method and exam anxiety. The regression exam results also revealed that meta-cognitive beliefs and smattering learning methods could positively predict and determine exam anxiety in students. A significant relationship was observed between meta-cognitive beliefs in females and males, and female students showed greater intention and interest toward meta-cognitive beliefs than males, however, no significant difference was observed between learning methods and exam anxiety in females and males. Conclusions It was concluded from the study results that profound learning methods lead to the

    Objective To better understand the relationship between childbirth and pelvic floor disorders the ideal study design would begin with data collection prior to but close in time to first pregnancy and follow participants through post-partum. We conducted a feasibility study to determine a) whether women desiring to get pregnant would agree to pre-pregnancy data collection including a one-time urethral catheter measure and repeat pelvic exams to ascertain a baseline within 6 months of pregnancy; b) effectiveness of various recruitment and retention methods, c) number achieving pregnancy, and then d) number expressing willingness to continue follow-up through pregnancy and postpartum. Methods Advertising included newspaper ads, targeted emails and flyers. Post-enrollment, four data collection visits were scheduled and occurred every 6 months or until pregnant. If pregnancy occurred, women were asked to indicate their willingness to continue assessments. Results The most successful advertising strategy for both recruitment and retention was local newspaper ads. 94 women inquired about the study, 30 enrolled. Post-baseline retention was 23 women at 6 months, 17 at 12 months, and 13 at 18 months. Nine of the 30 women achieved pregnancy; two remained eligible and willing to participate through pregnancy and postpartum. Conclusions This study provides data on feasibility of recruiting women to establish near-pregnancy clinical baseline measures that include pelvic exams. Close to 30% reached pregnancy within two years of study start and within 6 months of most recent pelvic exam measure. Of those who became pregnant, 22% expressed willingness to continue follow-up into the childbearing year. PMID:20713182

  10. Dominant and opponent relations in cortical function: An EEG study of exam performance and stress

    Directory of Open Access Journals (Sweden)

    Lucia P. Pavlova

    2017-12-01

    Full Text Available This paper analyzes the opponent dynamics of human motivational and affective processes, as conceptualized by RS Solomon, from the position of AA Ukhtomsky’s neurophysiological principle of the dominant and its applications in the field of human electroencephalographic analysis. As an experimental model, we investigate the dynamics of cortical activity in students submitting university final course oral examinations in naturalistic settings, and show that successful performance in these settings depends on the presence of specific types of cortical activation patterns, involving high indices of left-hemispheric and frontal cortical dominance, whereas the lack thereof predicts poor performance on the task, and seems to be associated with difficulties in the executive regulation of cognitive (intellectual and motivational processes in these highly demanding and stressful conditions. Based on such knowledge, improved educational and therapeutic interventions can be suggested which take into account individual variability in the neurocognitive mechanisms underlying adaptation to motivationally and intellectually challenging, stressful tasks, such as oral university exams. Some implications of this research for opponent-process theory and its closer integration into current neuroscience research on acquired motivations are discussed.

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

    Science.gov (United States)

    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.

    2008-10-01

    Full Text Available In this paper, we propose a conceptual and operational framework for process reengineering (PR in higher education (HE institutions. Using a case study aimed at streamlining exam scheduling and distribution in a distance learning (DL unit, we outline a sequential and non-linear four-step framework designed to reengineer processes. The first two steps of this framework – initiating and analyzing – are used to initiate, document, and flowchart the process targeted for reengineering, and the last two steps – reengineering/ implementing and evaluating – are intended to prototype, implement, and evaluate the reengineered process. Our early involvement of all stakeholders, and our in-depth analysis and documentation of the existing process, allowed us to avoid the traditional pitfalls associated with business process reengineering (BPR. Consequently, the outcome of our case study indicates a streamlined and efficient process with a higher faculty satisfaction at substantial cost reduction.

    Elbow dysplasia disease includes an united anconeal process, fragmented medial coronoid process, osteochondrosis of humeral trochlea, articular incongruity and degenerative joint disease. The aim of this study was to present detailed morphologic and morphometric aspects of the elbow joint in dog in clinical and correlate with radiographic and tomographic (CT) exam. Inter-observer variation for articular incongruity measurements by CT, comparative analysis in the radiographic exam, angle in ulnar notch and its comparative analysis between radiographic and tomographic agreement examination in 44 elbow of dogs with different ages were evaluated. The statistics analyses included the kappa coefficient and interclass correlation and Fischer's test and McNemar's test. It was evidenced that individual performance of each radiographic incidence had poor agreement with the tomographic exam, suggesting that the accomplishment of more than two radiograph views are needed. There was no agreement between the three evaluators in the ulnar notch angle at radiographic and tomographic exams. However, there was good/moderate agreement for articular incongruity measurement in the sagittal plane between evaluators. It was possible to conclude that none of the five radiographic incidences was better than the others for radiographic analysis because each incidence had a better identification of a particular elbow compartment; measurements at the tomographic exam to evaluate radioulnar incongruity had no reproductiveness in the frontal plane, but in sagittal plan had a good/moderate agreement between observers and the angle in ulnar notch presented no repeatability at radiographic exam and no reproductiveness at tomographic exam.

    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

    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.

    2015-06-01

    Full Text Available Background and purpose: Partial knowledge is one of the main factors to be considered when dealing with the improvement of the administration of Multiple Choice Questions (MCQ in testing. Various strategies have been proposed for this factor in the traditional testing environment. Therefore, this study proposed a Confidence Based Assessment (CBA as a pertinent solution and aims at comparing the effect of the CBA Scoring system with that of the conventional scoring systems (with and without negative score estimation as penalty on the students’ scores and estimating their partial knowledge on clinical studies.Methods: This comparative study was conducted using a standardized clinical knowledge exam for 117 clinical students. After two-step training, both the conventional MCQ and CBA examination was given in a single session simultaneously. The exam included 100 questions and the volunteers were requested to complete a questionnaire regarding their attitude and satisfaction on their first experience of the CBA after exam. A new confidence based marking system was selected for the scoring, which was a hybrid of the UCL and MUK2010 systems. The MCQ-Assistant, SPSS and Microsoft office Excel software were used for scoring and data analysis.Results: The mean age of the volunteers was 27.3±5.47, of whom 43.6% were men and 69.2% were senior medical students. Exam reliability was 0.977. The fit line of the MCQ scores without penalty estimation was R2=0.9816 and Intercept=18.125 or approximately.2 deviation in the low scores. The MCQ scoring with penalty had a fit line approximately parallel to the 45-degree line but on or above it and the CBA scoring fit line was nearer to the 45-degree line, parallel to it and a little below it. These two sets of scores had a significant p value0.037. The response percentage to the CBA is higher (p value=0.0001. The discrimination power of the MCQ and the CBA for the upper and lower 1/3 of the students was not

    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.

    2017-12-01

    Full Text Available To address the usually decontextualized transmission of information in biochemistry teaching, three interventions in a discipline (Metabolism for Biology majors were applied as innovative study guides. We describe the development, application, and evaluation of two study guides, contextualized with a real problem or an integrative view, using broad themes like evolution and metabolic adaptation. In order to evaluate the impact of both interventions on interest, motivation, and learning of the metabolic pathways, a design-based research with cycles of application and assessment was carried out, by means of classroom observation, grade analysis in written exams, and students’ interviews. Analysis and interpretation of the results point to benefits for teaching and learning, with helpful information to guide elaboration and refinement of new teaching materials and to make active learning more meaningful.

    1996-06-01

    To describe the relationship of Mini-Mental State Exam (MMSE) scores and changes over time in MMSE scores to age and education in a population of older women. A prospective study of a defined population. Various motherhouses and church-run health care facilities in the Eastern, Midwestern, and Southern regions of the United States. Catholic sisters (nuns) participating in the Nun Study, a study of aging and Alzheimer's Disease. The 678 participants were 75 to 102 years old (mean 83.3, standard deviation 5.5, median 82.3) at the time of the first functional assessment. Second assessments were obtained an average of 1.6 years later on 575 survivors. The outcome variables were MMSE scores at the first assessment (Time-one), and MMSE scores at the second assessment (Time-two). The independent variables were age at Time-one, and education (bachelor's degree or no bachelor's degree). Time-one MMSE scores decreased with age at Time-one. The decrease in MMSE scores with age was less in sisters with bachelor's degrees than in sisters without bachelor's degrees. The changes in MMSE scores had a "U-shaped" relationship with Time-one score, where the greatest declines occurred in sisters with intermediate Time-one scores. Stratified analysis by age, education, and Time-one MMSE scores of 20 or greater because of the small numbers of sisters with Time-one scores less than 20. In sisters with Time-one MMSE scores in the categories 20 to 23, 24 to 26, or 27 to 30, older ages at Time-one were associated with greater decline in those with bachelor's degrees, but not in those without bachelor's degrees. Also, lower education was associated with greater decline in sisters aged 75 to 84 years at Time-one, but this education effect disappeared or reversed in sisters who were 85 years of age or older at Time-one. Cognitive function as measured by the MMSE decreased with age at Time-one, most steeply as a function of age in those without bachelor's degrees. Cognitive function declined

    There is a need for accurate and precise food price elasticities (PE, change in consumer demand in response to change in price) to better inform policy on health-related food taxes and subsidies. The Price Experiment and Modelling (Price ExaM) study aims to: I) derive accurate and precise food PE values; II) quantify the impact of price changes on quantity and quality of discrete food group purchases and; III) model the potential health and disease impacts of a range of food taxes and subsidies. To achieve this, we will use a novel method that includes a randomised Virtual Supermarket experiment and econometric methods. Findings will be applied in simulation models to estimate population health impact (quality-adjusted life-years [QALYs]) using a multi-state life-table model. The study will consist of four sequential steps: 1. We generate 5000 price sets with random price variation for all 1412 Virtual Supermarket food and beverage products. Then we add systematic price variation for foods to simulate five taxes and subsidies: a fruit and vegetable subsidy and taxes on sugar, saturated fat, salt, and sugar-sweetened beverages. 2. Using an experimental design, 1000 adult New Zealand shoppers complete five household grocery shops in the Virtual Supermarket where they are randomly assigned to one of the 5000 price sets each time. 3. Output data (i.e., multiple observations of price configurations and purchased amounts) are used as inputs to econometric models (using Bayesian methods) to estimate accurate PE values. 4. A disease simulation model will be run with the new PE values as inputs to estimate QALYs gained and health costs saved for the five policy interventions. The Price ExaM study has the potential to enhance public health and economic disciplines by introducing internationally novel scientific methods to estimate accurate and precise food PE values. These values will be used to model the potential health and disease impacts of various food pricing policy

    2012-07-01

    To quantifiably measure the impact of self-instructed radiological anatomy modules on anatomy comprehension, demonstrated by radiology, gross, and written exams. Study guides for independent use that emphasized structural relationships were created for use with two online radiology atlases. A guide was created for each module of the first year medical anatomy course and incorporated as an optional course component. A total of 93 of 96 eligible students participated. All exams were normalized to control for variances in exam difficulty and body region tested. An independent t-test was used to compare overall exam scores with respect to guide completion or incompletion. To account for aptitude differences between students, a paired t-test of each student's exam scores with and without completion of the associated guide was performed, thus allowing students to serve as their own controls. Twenty-one students completed no study guides; 22 completed all six guides; and 50 students completed between one and five guides. Aggregate comparisons of all students' exam scores showed significantly improved mean performance when guides were used (radiology, 57.8% [percentile] vs. 45.1%, P < .001; gross, 56.9% vs. 46.5%, P = .001; written, 57.8% vs. 50.2%, P = .011). Paired comparisons among students who completed between one and five guides demonstrated significantly higher mean practical exam scores when guides were used (radiology, 49.3% [percentile] vs. 36.0%, P = .001; gross, 51.5% vs. 40.4%, P = .005), but not higher written scores. Radiological anatomy study guides significantly improved anatomy comprehension on radiology, gross, and written exams. Copyright © 2012 AUR. Published by Elsevier Inc. All rights reserved.

    There is great interest in positron emission tomography (PET)/magnetic resonance (MR) as a clinical tool due to its capacity to provide diverse diagnostic information in a single exam. The goal of this exam is to compare the diagnostic accuracy of PET/MR-acquired [F-18]2-fluoro-2-deoxyglucose (FDG) brain exams to that of PET/CT with respect to identifying seizure foci in children with localization-related epilepsy. Institutional Review Board approval and informed consent were obtained for this Health Insurance Portability and Accountability Act-compliant, prospective study. All patients referred for clinical FDG-PET/CT exams of the brain at our institution for a diagnosis of localization-related epilepsy were prospectively recruited to undergo an additional FDG-PET acquisition on a tandem PET/MR system. Attenuation-corrected FDG images acquired at PET/MR and PET/CT were interpreted independently by five expert readers. Readers were blinded to the scanner used for acquisition and attenuation correction as well as all other clinical and imaging data. A Likert scale scoring system (1-5) was used to assess image quality. The locale of seizure origin determined at multidisciplinary epilepsy surgery work rounds was considered the reference standard. Non-inferiority testing for paired data was used to compare the diagnostic accuracy of PET/MR to that of PET/CT. The final study population comprised 35 patients referred for a diagnosis of localization-related epilepsy (age range: 2-19 years; median: 11 years; 21 males, 14 females). Image quality did not differ significantly between the two modalities. The accuracy of PET/MR was not inferior to that of PET/CT for localization of a seizure focus (P=0.017). The diagnostic accuracy of FDG-PET images acquired on a PET/MR scanner and generated using MR-based attenuation correction was not inferior to that of PET images processed by traditional CT-based correction.

    There is great interest in positron emission tomography (PET)/magnetic resonance (MR) as a clinical tool due to its capacity to provide diverse diagnostic information in a single exam. The goal of this exam is to compare the diagnostic accuracy of PET/MR-acquired [F-18]2-fluoro-2-deoxyglucose (FDG) brain exams to that of PET/CT with respect to identifying seizure foci in children with localization-related epilepsy. Institutional Review Board approval and informed consent were obtained for this Health Insurance Portability and Accountability Act-compliant, prospective study. All patients referred for clinical FDG-PET/CT exams of the brain at our institution for a diagnosis of localization-related epilepsy were prospectively recruited to undergo an additional FDG-PET acquisition on a tandem PET/MR system. Attenuation-corrected FDG images acquired at PET/MR and PET/CT were interpreted independently by five expert readers. Readers were blinded to the scanner used for acquisition and attenuation correction as well as all other clinical and imaging data. A Likert scale scoring system (1-5) was used to assess image quality. The locale of seizure origin determined at multidisciplinary epilepsy surgery work rounds was considered the reference standard. Non-inferiority testing for paired data was used to compare the diagnostic accuracy of PET/MR to that of PET/CT. The final study population comprised 35 patients referred for a diagnosis of localization-related epilepsy (age range: 2-19 years; median: 11 years; 21 males, 14 females). Image quality did not differ significantly between the two modalities. The accuracy of PET/MR was not inferior to that of PET/CT for localization of a seizure focus (P=0.017).

    Full Text Available Background: Distance education methods have taken on greater importance as medical student education has moved off campus into the community. What the best methods are for conveying information to students at distant sites has not been determined. Objective: To determine if students at distant community sites who received an otitis media study case by e-mail that was enhanced with a referral to a web-based otitis study case, performed better on otitis OSCE stations than students who received the same case not enhanced with visuals or referrals to a web-based otitis case. Design/Methods: Students were randomized by community site to receive either the enhanced (E or simple otitis study case (S. Students were e-mailed an otitis media study case during the 5th week of the rotation. Those randomized to the E-case received a case that started with a case scenario followed by a "Task" that instructed them to go to this web address: http://www.aap.org/otitismedia/www/vc/ear/index.cfm (American Academy of Pediatrics Otitis Web Site. They were then to select "Case 1" which was a continuation of the case scenario present on their e-mail. A list of learning objectives was also printed on the e-mail. Students receiving the S-case viewed the same case scenario and objectives, but were not instructed to go to the web page. All students rotated through two OSCE otitis stations. In the first station they interviewed a simulated patient(OSCE-SP and counseled her on the management of her 12 month old with otitis. Within that station they viewed a video of a pneumoscopic exam of two ears, one ear with otitis and the other ear normal. At the 2nd otitis station the student presented the case to a faculty and was asked a series of questions about otitis media(OSCE-PR. Scores on the two stations were compared by group. Results: There were 198 students who took the OSCE. 178 (90% responded to a survey that indicated they had opened and read the e-mailed case. There

    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

  2. Guided mode studies of smectic liquid crystals

    Recently there has been considerable interest in the use of ferroelectric liquid crystals in low power, fast switching display devices. At present the voltage switching process in surface stabilised ferroelectric liquid crystal (SSFLC) devices is not fully understood and a convenient theory for such cells has yet to be found. It is the primary aim of this work to characterise the optic tensor configuration (director profile) in thin cells (∼ 3.5 μm) containing ferroelectric liquid crystal (FLC) material. These results form a benchmark by which continuum theories may be tested. Polarised microscopy is, perhaps, the most common optical probe of liquid crystal cells. It should be appreciated that this technique is fundamentally limited, as the results are deduced from an integrated optical response of any given cell, and cannot be used to spatially resolve details of the director profile through the cell. The guided mode techniques used in this study are the primary non-integral probe and enable detailed spatial resolution of the director profile within liquid crystal cells. Analysis of guided mode data from cells containing homeotropically aligned FLC reveals the temperature dependence of the optical biaxiality and cone angle for a 40% chiral mixture of the commercially available FLC SCE8*. From these optical biaxiality measurements the temperature dependence of the biaxial order parameter C is determined. Guided mode studies of cells containing homogeneously aligned SCE8* (the conventional alignment for SSFLC devices) reveal the 0V equilibrium director profile from which a cone and chevron model is constructed. Subsequent studies of voltage induced elastic deformations of the director profile are presented and compared with a single elastic constant continuum theory which is shown to be inadequate. Optical guided mode techniques are not directly sensitive to the smectic layer configuration but X-ray scattering is. Here, for the first time, results are presented

    Full Text Available One of the difficulties for biochemistry learning is the persistence of traditional teaching methods, based on transmission and memorization of abstract and detailed information, usually in a decontextualized way. Such scenario results in surface learning and content reproduction. In order to address these problems, three interventions in a discipline (Metabolism for Biology majors were applied, in the form of innovative teaching tools (study guides. OBJECTIVES: The main goal is to evaluate the impact of these interventions on interest, motivation, and learning of the metabolic pathways. MATERIALS AND METHODS: We describe the development, application, and evaluation of two study guides – one created from a problem used as a contextual connection for glycogen metabolism study and another embedding an integrative view based on glutamate metabolism. Both materials were guided by broad themes like evolution, metabolic adaptation, and comparative biochemistry. The development of the study guides combined submicroscopic (molecular and macroscopic (body, environment levels, aiming to motivate reading and discussion. A design-based research with cycles of application and assessment was carried out, by means of classroom observation, grade analysis in written exams, and students’ interviews. RESULTS AND DISCUSSION: In general, based on in-class student feedback to professors and to the researcher in the interviews, the study guides arouse curiosity and fostered peer discussion. Final average grades indicate a good global performance in all proposed activities. Whole data from study guides’ application in classroom evidenced their impact on interest, motivation, and learning. The strategy of developing problem or integrative situation linking molecular (micro and contextual (macro levels were helpful to foster critical thinking and to value topics of scientific literacy. CONCLUSIONS: Analysis and interpretation of the results point to benefits for

    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.

  19. 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.

    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

    In recent years, the Mini-Mental State Examination (MMSE) has been widely used and has been proposed for cognitive decline screening in the framework of a systematic geriatric evaluation in health centers. The aim of the present longitudinal study was to identify the potential determinants of MMSE score and its evolution over a 4-year period in a population aged over sixty years with good general health without dementia and consulting for a health check-up. Longitudinal study. The preventive medical center (CMP) in Nancy. 687 subjects over 60 years of age (mean age 65.6 ± 5.07 years) were included from the Senior health examination study. All subjects underwent 2 visits over a period of 4 years. MMSE measurement and a self-administered questionnaire of emotional and psychological state were evaluated at baseline and at the follow-up visit. The major components of total variance of baseline MMSE were represented by education level, practice of regular physical activity, nervousness and despair. Multivariate analysis identified 3 variables at baseline visit that independently predicted annual changes in MMSE: MMSE score, education level and "Difficulty in social relations" (r= -0.222, 0.154 and -0.255 respectively). Education level and several psychological factors may influence MMSE score and its evolution over time in community-dwelling subjects aged over 60 years without dementia. In these subjects, a low MMSE score does not predict cognitive decline over a period of 4 years. Therefore, the reliability of MMSE in this type of population is questionable.

    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 .

  11. 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.

    Purpose: To validate the accuracy of a Monte Carlo source model of the Siemens SOMATOM Sensation 16 CT scanner using organ doses measured in physical anthropomorphic phantoms. Methods: The x-ray output of the Siemens SOMATOM Sensation 16 multidetector CT scanner was simulated within the Monte Carlo radiation transport code, MCNPX version 2.6. The resulting source model was able to perform various simulated axial and helical computed tomographic (CT) scans of varying scan parameters, including beam energy, filtration, pitch, and beam collimation. Two custom-built anthropomorphic phantoms were used to take dose measurements on the CT scanner: an adult male and a 9-month-old. The adult male is a physical replica of University of Florida reference adult male hybrid computational phantom, while the 9-month-old is a replica of University of Florida Series B 9-month-old voxel computational phantom. Each phantom underwent a series of axial and helical CT scans, during which organ doses were measured using fiber-optic coupled plastic scintillator dosimeters developed at University of Florida. The physical setup was reproduced and simulated in MCNPX using the CT source model and the computational phantoms upon which the anthropomorphic phantoms were constructed. Average organ doses were then calculated based upon these MCNPX results. Results: For all CT scans, good agreement was seen between measured and simulated organ doses. For the adult male, the percent differences were within 16% for axial scans, and within 18% for helical scans. For the 9-month-old, the percent differences were all within 15% for both the axial and helical scans. These results are comparable to previously published validation studies using GE scanners and commercially available anthropomorphic phantoms. Conclusions: Overall results of this study show that the Monte Carlo source model can be used to accurately and reliably calculate organ doses for patients undergoing a variety of axial or helical CT

  13. THE FACTORS INFLUENCING THE MATHEMATICS EXAM SUCCESS RATE IN THE STUDY PROGRAMMES TAUGHT AT THE COLLEGE OF POLYTECHNICS JIHLAVA (2006–2015

    Full Text Available This paper addresses the exam success rates in Mathematics 1 at the College of Polytechnics in Jihlava (CPJ. Primary data taken from the school information system cover the years 2006–2015. We carried out a success rate analysis based on several criteria (form of study, the reason for termination of studies, gender. We observed the dependence of the success rate on the aforementioned criteria and time. Plus a detailed analysis of the success rate with respect to the study programme was conducted. The contingency tables analysis and correspondence analysis were used to assess the dependencies. The research showed that the success rate in Mathematics 1 has been decreasing over the course of the monitored period of time. The success rate of full-time students is higher compared to the part-time students. Women have higher success rate than men. The respective study programmes showed equivalent results. Technical study programmes show lower success rate in mathematics. The research furthermore implies that mathematics may not always be the cause of a complete termination of studies. To reverse the trend of the growing failure rate we introduced an entrance test of high school basic mathematics followed by a course for those who fail at this test. As a part of our currently running project, our school have been innovating the e-learning modules and working on the textbooks for Seminar in Mathematics that may be completed in a form of an intensive summer or winter school in mathematics. This project’s objective is an overall improvement of students’ mathematical knowledge and skills.

    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.

    Full Text Available Evaluation of course outcome is one of the important elements in assessing students’ performance in higher institutions. Most of the courses depend on examination result as a medium to evaluate the level of students’ performances. In this study, the final exam questions of Vector Calculus course KKKQ1123 is being used to assess the difficulty index and discrimination index. 80 students from Department of Mechanical and Materials (JKMB were involved in this study. This study found that the range of difficulty index is between 0.2 and 0.8, where the question that was categorized as difficult is question number 6 whereas for easy questions is question number 3. Meanwhile the range obtained for discrimination index was in the acceptable range, that is, between 0.2 and 0.6 which indicates that the exam questions are good. With this study, it is hope that it will guide the lecturers in constructing and crafting a good and reliable exam questions consistent with the level of student's ability.

  3. Behavioral economics and diabetic eye exams.

    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.

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

    Day, E. A.; D'Arcy, M. K.; Craig, L.; Streule, M. J.; Passmore, E.; Irving, J. C. E.

    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.

  5. 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.

    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.

There are two dose index in CT, the CTDI{sub vol} and DLP that represents the Computed Tomography dose index and the product of the CTDI{sub vol} by the length of irradiation. This paper has as objective describe the values of CTDI{sub vol} e DLP for pediatric exams of chest and head. This is an exploratory study of bibliography revision on the PubMed data base using the index terms with the following crossing: Computed Tomography AND Reference Levels AND Dose. The search was limited by published studies on the last 5 years with patients among 0 and 15 years, in English or Portuguese. Besides that, were included references guides suggest by scientific and governmental organizations on the last 5 years. The data analysis was made using the four readings of Gil: exploratory, selective, analytic and interpretative. By the Exploratory Reading were located 23 articles. On the Selective Reading were excluded 4 articles and on the Analytic Reading 9 articles. The Interpretative Reading was made using 7 publications. Regarding the references guides were includes 3 guides. The Portaria MS453/98 was included for being the only national publication. All data were characterized between practical levels and reference levels. The conclusion is that there is no consensus between the reference levels for the selected articles, for pediatric exams. Besides that, the national legislation do not have reference levels for pediatric CT. (author)

    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.

    Pinto, Gabriella M.; Sa, Lidia Vasconcellos de

    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

  8. Systematic study on the performance of elliptic focusing neutron guides

    International Nuclear Information System (INIS)

    Martin Rodriguez, D.; DiJulio, D.D.; Bentley, P.M.

    2016-01-01

    In neutron scattering experiments there is an increasing trend towards the study of smaller volume samples, which make the use of focusing optics more important. Focusing guide geometries based on conic-sections, such as those with parabolic and elliptic shapes, have been extensively used in both recently built neutron instruments and upgrades of existing hardware. A large fraction of proposed instruments at the European Spallation Source feature the requirement of good performance when measuring on small samples. The optimised design of a focusing system comes after time consuming Monte-Carlo (MC) simulations. Therefore, in order to help reduce the time needed to design such focusing systems, it is necessary to study systematically the performance of focusing guides. In the present work, we perform a theoretical analysis of the focusing properties of neutron beams, and validate them using a combination of Monte-Carlo simulations and Particle Swarm Optimisations (PSOs), where there is a close correspondence between the maximum divergence of the beam and the shape of the guide. The analytical results show that two limits can be considered, which bound a range of conic section shapes that provide optimum performance. Finally, we analyse a more realistic guide example and we give an assessment of the importance of the contribution from multiple reflections in different systems.

    2013-01-01

    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. Literature review, outpatient, technology, visual privacy.

    The Computed Tomography (CT) imaging diagnosis it is responsible for over 34% of the radiation dose given to society, only in Brazil there is around 3833 CT equipment. There are two dose index in CT, the CTDI vol and DLP that represents the Computed Tomography dose index and the product of the CTDI vol by the length of irradiation. This paper has as objective describe the values of CTDI vol e DLP for pediatric exams of chest and head. This is an exploratory study of bibliography revision on the PubMed data base using the index terms with the following crossing: Computed Tomography AND Reference Levels AND Dose. The search was limited by published studies on the last 5 years with patients among 0 and 15 years, in English or Portuguese. Besides that, were included references guides suggest by scientific and governmental organizations on the last 5 years. The data analysis was made using the four readings of Gil: exploratory, selective, analytic and interpretative. By the Exploratory Reading were located 23 articles. On the Selective Reading were excluded 4 articles and on the Analytic Reading 9 articles. The Interpretative Reading was made using 7 publications. Regarding the references guides were includes 3 guides. The Portaria MS453/98 was included for being the only national publication. All data were characterized between practical levels and reference levels. The conclusion is that there is no consensus between the reference levels for the selected articles, for pediatric exams. Besides that, the national legislation do not have reference levels for pediatric CT. (author)

    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.

    2016-01-01

    Hair follicles (HFs) undergo lifelong cyclical transformations, progressing through stages of rapid growth (anagen), regression (catagen), and relative "quiescence" (telogen). Given that HF cycling abnormalities underlie many human hair growth disorders, the accurate classification of individual cycle stages within skin biopsies is clinically important and essential for hair research. For preclinical human hair research purposes, human scalp skin can be xenografted onto immunocompromised mice to study human HF cycling and manipulate long-lasting anagen in vivo. Although available for mice, a comprehensive guide on how to recognize different human hair cycle stages in vivo is lacking. In this article, we present such a guide, which uses objective, well-defined, and reproducible criteria, and integrates simple morphological indicators with advanced, (immuno)-histochemical markers. This guide also characterizes human HF cycling in xenografts and highlights the utility of this model for in vivo hair research. Detailed schematic drawings and representative micrographs provide examples of how best to identify human HF stages, even in suboptimally sectioned tissue, and practical recommendations are given for designing human-on-mouse hair cycle experiments. Thus, this guide seeks to offer a benchmark for human hair cycle stage classification, for both hair research experts and newcomers to the field. Copyright © 2015 The Authors.

    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

  17. Sample holder for studying temperature dependent particle guiding

    International Nuclear Information System (INIS)

    Bereczky, R.J.; Toekesi, K.; Kowarik, G.; Aumayr, F.

    2011-01-01

    Complete text of publication follows. The so called guiding effect is a complex process involving the interplay of a large number of charged particles with a solid. Although many research groups joined this field and carried out various experiments with insulator capillaries many details of the interactions are still unknown. We investigated the temperature dependence of the guiding since it opens new possibilities both for a fundamental understanding of the guiding phenomenon and for applications. For the temperature dependent guiding experiments a completely new heatable sample holder was designed. We developed and built such a heatable sample holder to make accurate and reproducible studies of the temperature dependence of the ion guiding effect possible. The target holder (for an exploded view see Fig. 1) consists of two main parts, the front and the back plates. The two plates of the sample holder, which function as an oven, are made of copper. These parts surround the capillary in order to guarantee a uniform temperature along the whole tube. The temperature of the copper parts is monitored by a K-Type thermocouple. Stainless steel coaxial heaters surrounding the oven are used for heating. The heating power up to a few watts is regulated by a PID controller. Cooling of the capillary is achieved by a copper feed-through connected to a liquid nitrogen bath outside the UHV chamber. This solution allows us to change the temperature of the sample from -30 deg C up to 90 deg C. Our experiments with this newly developed temperature regulated capillary holder show that the glass temperature (i.e. conductivity) can be used to control the guiding properties of the glass capillary and adjust the conditions from guiding at room temperature to simple geometrical transmission at elevated temperatures. This holds the promise to investigate the effect of conductivity on particle transport (build-up and removal of charge patches) through capillaries in more details

  2. 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

    We demonstrate the guiding of a supersonic heavy-water (D 2 O) molecular beam using a hollow electrostatic field generated by the combination of two parallel charged-wires and two grounded metal-plates, and report some new and preliminary experimental results. In the experiment, we detect the guiding signals by using the method of time-of-flight mass spectrum and study the dependence of the relative transmission of the beam guide on the guiding voltage. Our study shows that the relative transmission of the beam guide is increased linearly with increasing guiding voltage V guid , and the number of the guided D 2 O molecules is at least increased by 89.4% when the guiding voltage is +20.0 kV. Finally, some potential applications of our guiding scheme in the molecule optics are briefly discussed. (authors)

    2015-09-04

    We investigated prospective associations between physical activity/sedentary behaviour (PA/SED) and General Certificate of Secondary Education (GCSE) results in British adolescents. Exposures were objective PA/SED and self-reported sedentary behaviours (screen (TV, Internet, Computer Games)/non-screen (homework, reading)) measured in 845 adolescents (14·5y ± 0·5y; 43·6 % male). GCSE results at 16y were obtained from national records. Associations between exposures and academic performance (total exam points) were assessed using multilevel mixed-effects linear regression adjusted for mood, BMI z-score, deprivation, sex, season and school; potential interactions were investigated. PA was not associated with academic performance. One-hour more accelerometer-assessed SED was associated with (β(95 % CI)) 6·9(1·5,12·4) more GCSE points. An extra hour of screen time was associated with 9.3(-14·3,-4·3) fewer points whereas an extra hour of non-screen time (reading/homework) was associated with 23·1(14·6,31·6) more points. Screen time was still associated with poorer scores after adjusting for objective PA/SED and reading/homework. An extra hour/day of screen time at 14·5y is approximately equivalent to two fewer GCSE grades (e.g., from B to D) at 16y. Strategies to achieve the right balance between screen and non-screen time may be important for improving academic performance. Concerns that encouraging more physical activity may result in decreased academic performance seem unfounded.

  17. Feasibility study of a hand guided robotic drill for cochleostomy.

    Science.gov (United States)

    Brett, Peter; Du, Xinli; Zoka-Assadi, Masoud; Coulson, Chris; Reid, Andrew; Proops, David

    2014-01-01

    The concept of a hand guided robotic drill has been inspired by an automated, arm supported robotic drill recently applied in clinical practice to produce cochleostomies without penetrating the endosteum ready for inserting cochlear electrodes. The smart tactile sensing scheme within the drill enables precise control of the state of interaction between tissues and tools in real-time. This paper reports development studies of the hand guided robotic drill where the same consistent outcomes, augmentation of surgeon control and skill, and similar reduction of induced disturbances on the hearing organ are achieved. The device operates with differing presentation of tissues resulting from variation in anatomy and demonstrates the ability to control or avoid penetration of tissue layers as required and to respond to intended rather than involuntary motion of the surgeon operator. The advantage of hand guided over an arm supported system is that it offers flexibility in adjusting the drilling trajectory. This can be important to initiate cutting on a hard convex tissue surface without slipping and then to proceed on the desired trajectory after cutting has commenced. The results for trials on phantoms show that drill unit compliance is an important factor in the design.

This can be important to initiate cutting on a hard convex tissue surface without slipping and then to proceed on the desired trajectory after cutting has commenced. The results for trials on phantoms show that drill unit compliance is an important factor in the design.

    The use of curved guide tubes for transporting frozen hydrogen pellets offers great flexibility for pellet injection into plasma devices. While this technique has been previously employed, an increased interest in its applicability has been generated with the recent ASDEX Upgrade experimental data for magnetic high-field side (HFS) pellet injection. In these innovative experiments, the pellet penetration appeared to be significantly deeper than for the standard magnetic low-field side injection scheme, along with corresponding greater fueling efficiencies. Thus, some of the major experimental fusion devices are planning experiments with HFS pellet injection. Because of the complex geometries of experimental fusion devices, installations with multiple curved guide tube sections will be required for HFS pellet injection. To more thoroughly understand and document the capability of curved guide tubes, an experimental study is under way at the Oak Ridge National Laboratory (ORNL). In particular, configurations and pellet parameters applicable for the DIII-D tokamak and the International Thermonuclear Experimental Reactor (ITER) were simulated in laboratory experiments. Initial test results with nominal 2.7- and 10-mm-diam deuterium pellets are presented and discussed

    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.

    For the sake of improving the performance of the neutron scattering instrument, usually we need use the neutron guide, it's very important to select the right type and optimizing of neutron guide. The papers calculate the focus neutron guide and the single channel neutron guide by numeric method. The results shows that the choice of neutron guide should consult the resolution requirement of neutron scattering instrument, and the length of the neutron guide should be optimized. The calculation results can be the theoretical reference for the design of neutron scattering instrument. (authors)

    The GUIDE-IT (Guiding Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure) study is designed to determine the safety, efficacy, and cost-effectiveness of a strategy of adjusting therapy with the goal of achieving and maintaining a target N-terminal pro-B-type natriuretic peptide (NT-proBNP) level of levels provide key prognostic information in patients with HF. Therapies proven to improve outcomes in patients with HF are generally associated with decreasing levels of NPs, and observational data show that decreases in NP levels over time are associated with favorable outcomes. Results from smaller prospective, randomized studies of this strategy thus far have been mixed, and current guidelines do not recommend serial measurement of NP levels to guide therapy in patients with HF. GUIDE-IT is a prospective, randomized, controlled, unblinded, multicenter clinical trial designed to randomize approximately 1,100 high-risk subjects with systolic HF (left ventricular ejection fraction ≤40%) to either usual care (optimized guideline-recommended therapy) or a strategy of adjusting therapy with the goal of achieving and maintaining a target NT-proBNP level of study are followed up at regular intervals and after treatment adjustments for a minimum of 12 months. The primary endpoint of the study is time to cardiovascular death or first hospitalization for HF. Secondary endpoints include time to cardiovascular death and all-cause mortality, cumulative mortality, health-related quality of life, resource use, cost-effectiveness, and safety. The GUIDE-IT study is designed to definitively assess the effects of an NP-guided strategy in high-risk patients with systolic HF on clinically relevant endpoints of mortality, hospitalization, quality of life, and medical resource use.

    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)

  5. Sample Size in Qualitative Interview Studies: Guided by Information Power.

    Sample sizes must be ascertained in qualitative studies like in quantitative studies but not by the same means. The prevailing concept for sample size in qualitative studies is "saturation." Saturation is closely tied to a specific methodology, and the term is inconsistently applied. We propose the concept "information power" to guide adequate sample size for qualitative studies. Information power indicates that the more information the sample holds, relevant for the actual study, the lower amount of participants is needed. We suggest that the size of a sample with sufficient information power depends on (a) the aim of the study, (b) sample specificity, (c) use of established theory, (d) quality of dialogue, and (e) analysis strategy. We present a model where these elements of information and their relevant dimensions are related to information power. Application of this model in the planning and during data collection of a qualitative study is discussed. © The Author(s) 2015.

    The objective of this study was to describe the suprascapular nerve block using CT guidance and to evaluate the short- and medium-term efficacy in a range of shoulder pathologies. CT-guided infiltration around the suprascapular nerve was performed with bupivacaine and Celestone Chronodose on 40 consecutive patients presenting with chronic shoulder pathologies unresponsive to conventional treatment. Patients were interviewed using the Shoulder Pain and Disability Index (SPADI) before the procedure, 30 min after the procedure and at 3 days, 3 weeks and 6 weeks afterwards. Within 30 min of the block overall pain scores decreased from a mean ({+-}SEM) pain score of 7.0 ({+-}0.4) to 3.5 ({+-}0.5) (n=39, P<0.001). At 3 days after the procedure, the mean overall improvement of the pain and disability scores were 20.4% ({+-}4.9, P<0.001) and 16.8% ({+-}4.8, P=0.004) respectively. Sustained pain relief and reduced disability were achieved in 10 of 35 (29%) patients at 3 weeks and longer. Patients suffering from soft tissue pathologies were the most likely patients to benefit from the injection. No serious side effects were noted. In some patients with chronic soft tissue pathologies who do not respond to conventional treatment, a CT-guided suprascapular nerve block can provide safe short- and medium-term relief from pain and disability.

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

    Science.gov (United States)

    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

    Ten percent to 15% of urinary catheterizations involve complications. New techniques to reduce risks and pain are indicated. This study examines the feasibility and safety of male urinary catheterization by nursing personnel using a visually guided device in a clinical setting. The device, a 0.6-mm fiber-optic bundle inside a 14F triple-lumen flexible urinary catheter with a lubricious coating, irrigation port, and angled tip, connects to a camera, allowing real-time viewing of progress on a color monitor. Two emergency nurses were trained to use the device. Male patients 18 years or older presenting to the emergency department with an indication for urinary catheterization using a standard Foley or Coudé catheter were eligible to participate in the study. Exclusion criteria were a current suprapubic tube or gross hematuria prior to the procedure. Twenty-five patients were enrolled. Data collected included success of placement, total procedure time, pre-procedure pain and maximum pain during the procedure, gross hematuria, abnormalities or injuries identified if catheterization failed, occurrence of and reason for equipment failures, and number of passes required for placement. All catheters were successfully placed. The median number of passes required was 1. For all but one patient, procedure time was ≤ 17 minutes. A median increase in pain scores of 1 point from baseline to the maximum was reported. Gross hematuria was observed in 2 patients. The success rate for placement of a Foley catheter with the visually guided device was 100%, indicating its safety, accuracy, and feasibility in a clinical setting. Minimal pain was associated with the procedure. Copyright © 2013 Emergency Nurses Association. Published by Mosby, Inc. All rights reserved.

  15. Intraoperative positioning of the hindfoot with the hindfoot alignment guide: a pilot study.

    Science.gov (United States)

    Frigg, Arno; Jud, Lukas; Valderrabano, Victor

    2014-01-01

    In a previous study, intraoperative positioning of the hindfoot by visual means resulted in the wrong varus/valgus position by 8 degrees and a relatively large standard deviation of 8 degrees. Thus, new intraoperative means are needed to improve the precision of hindfoot surgery. We therefore sought a hindfoot alignment guide that would be as simple as the alignment guides used in total knee arthroplasty. A novel hindfoot alignment guide (HA guide) has been developed that projects the mechanical axis from the tibia down to the heel. The HA guide enables the positioning of the hindfoot in the desired varus/valgus position and in plantigrade position in the lateral plane. The HA guide was used intraoperatively from May through November 2011 in 11 complex patients with simultaneous correction of the supramalleolar, tibiotalar, and inframalleolar alignment. Pre- and postoperative Saltzman views were taken and the position was measured. The HA guide significantly improved the intraoperative positioning compared with visual means: The accuracy with the HA guide was 4.5 ± 5.1 degrees (mean ± standard deviation) and without the HA guide 9.4 ± 5.5 degrees (P guide (2 avoided osteotomies, 5 additional osteotomies). The HA guide helped to position the hindfoot intraoperatively with greater precision than visual means. The HA guide was especially useful for multilevel corrections in which the need for and the amount of a simultaneous osteotomy had to be evaluated intraoperatively. Level IV, case series.

  16. Auricular Acupuncture for Exam Anxiety in Medical Students-A Randomized Crossover Investigation.

    Directory of Open Access Journals (Sweden)

    Catharina Klausenitz

    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.

    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.

  6. Study of guided modes in three-dimensional composites

    Science.gov (United States)

    Baste, S.; Gerard, A.

    The propagation of elastic waves in a three-dimensional carbon-carbon composite is modeled with a mixed variational method, using the Bloch or Floquet theories and the Hellinger-Reissner function for two independent fields. The model of the equivalent homogeneous material only exists below a cut-off frequency of about 600 kHz. The existence below the cut-off frequency of two guided waves can account for the presence of a slow guided wave on either side of the cut-off frequency. Optical modes are generated at low frequencies, and can attain high velocites (rapid guided modes of 15,000 m/sec).

    2012-01-01

    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

    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.

    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 purpose of this qualitative inquiry was to explore and describe the perspectives of local English teachers on the National Standardized Exam [NSE] policy as a high-stakes exam to gauge student performance nationally at four senior high schools in Jambi City, Indonesia. The theoretical framework of the ethics of critique, justice, and care was used to guide this study. Data for this study are collected through a demographic background survey and in-depth interviews with fifteen local English teachers. The demographic data were analyzed descriptively. The interviews data were analyzed using within-case and cross-case displays and analyses. Two salient themes with their subthemes that emerged were (1 negative perspectives on the practices and accuracy of the NSE policy and (2 unintended consequences the NSE policy (curriculum and instruction, teaching and learning, teacher motivation, student motivation, less attention to non-tested disciplines, and widespread cheating. This study provides information for policy makers, school leaders, researchers, and teacher educators to understand how the policy is implemented at the school level. Policy implications are discussed

    The effects of electronic health records (EHRs) on doctor-patient communication are unclear. To evaluate the effects of EHR use compared with paper chart use, on novice physicians' communication skills. Within-subjects randomized controlled trial using observed structured clinical examination methods to assess the impact of use of an EHR on communication. A large academic internal medicine training program. First-year internal medicine residents. Residents interviewed, diagnosed, and initiated treatment of simulated patients using a paper chart or an EHR on a laptop computer. Video recordings of interviews were rated by three trained observers using the Four Habits scale. Thirty-two residents completed the study and had data available for review (61.5% of those enrolled in the residency program). In most skill areas in the Four Habits model, residents performed at least as well using the EHR and were statistically better in six of 23 skills areas (pcommunication score was better when using an EHR: mean difference 0.254 (95% CI 0.05 to 0.45), p = 0.012, Cohen's d of 0.47 (a moderate effect). Residents scoring poorly (>3 average score) with paper methods (n = 8) had clinically important improvement when using the EHR. This study was conducted in first-year residents in a training environment using simulated patients at a single institution. Use of an EHR on a laptop computer appears to improve the ability of first-year residents to communicate with patients relative to using a paper chart. © The Author 2014.

    Objective: To discuss the feasibility of the time to peak of cerebral CT perfusion (CTP) in predicting the scan-delay-time after contrast media administration in cerebral and cervical CT angiography (CTA). Methods: Retrospective Analysis was performed in eighty patients who had been examined with cerebral and cervical CTA, they were divided randomly into two groups. Group A:40 patients were performed by the method of experience of 20 seconds as scan-delay-time. Group B:the other 40 patients were examined with the combination scanning technology of CTP-CTA. They were all measured with enhancement value of CT in the M1 segment of left middle cerebral artery, superior sagittal sinus , left common carotid artery adjacent to the fourth cervical vertebrace and internal jugular vein, and then calculate the difference between the arterys and the veins in the same layer. Statistical significance was determined with t test. Results: (1)The enhancement value of CT in the cerebral and cervical artery vessels and the resolving power between the arterys and the veins in the same layer of group B were higher than that in group A. (2) Group B whose cerebral and cervical artery vessels rescontructed from the raw CT data set showed clearly; There were an advance in 3 cases (7.5%), a delay in 5 cases (12.5%) in group A whose cerebral and cervical artery vessels rescontructed from the raw CT data set didn't show clearly.Conclusion It's a satisfactory method based on successful cerebral and cervical CTA study to take the time to peak in CT perfusion as the scan-delay-time during the combined examination of CTP and CTA with 64-detector spiral CT.

    2005-01-01

    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.

    2009-01-01

    According to DSM-IV, personality disorder constitutes a class only when personality traits are inflexible and maladaptive and cause either significant functional impairment or subjective distress. Classical treatment of choice for personality disorders has been psychotherapy and/or psychopharmacotherapy. Our study is to determine if subjects with antisocial personality disorders will benefit from quantitative EEG (qEEG) guided neurofeedback treatment. Thirteen subjects (9 male, 4 female) ranged in age from 19 to 48 years. All the subjects were free of medications and illicit drugs. We excluded subjects with other mental disorders by clinical assessment. Psychotherapy or psychopharmacotherapy or any other treatment model was not introduced to any of the subjects during or after neurofeedback treatment. For the subject who did not respond to neurofeedback, training was applied with 38 sessions of LORETA neurofeedback training without success. Evaluation measures included qEEG analysis with Nx Link data base, MMPI, T.O.V.A tests and SA-45 questionaries at baseline, and at the end of neurofeedback treatment. Lexicor qEEG signals were sampled at 128 Hz with 30 minutes-neurofeedback sessions completed between 80-120 sessions depending on the case, by Biolex neurofeedback system. At baseline and after every 20 sessions, patients were recorded with webcam during the interview. Twelve out of 13 subjects who received 80-120 sessions of neurofeedback training showed significant improvement based on SA-45 questionaries, MMPI, T.O.V.A. and qEEG/Nx Link data base (Neurometric analysis) results, and interviewing by parent/family members. Neurofeedback can change the view of psychiatrists and psychologists in the future regarding the treatment of personality disorders. This study provides the first evidence for positive effects of neurofeedback treatment in antisocial personality disorders. Further study with controls is warranted.

    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

    2004-01-01

    Improved tape guiding and tape dimensional stability are essential for magnetic tape linear recoding formats to take advantage of vastly increased track density and thereby achieve higher storage capacities. Tape guiding is dependent on numerous parameters, such as type of the guides and tape path geometry, quality of virgin tape edge, drive operating parameters (e.g., tape speed and tape tension), mechanical properties of the tape, and tape geometry (e.g., cupping and curvature). The objective of the present study is to evaluate guiding and tribological performance of single-flanged guides with porous air bearings in a linear tape drive. A comparison of guiding performance of the dual flanged stationary guides and single-flanged guides with porous air bearings is performed. The effect of tape path geometry, drive operating conditions (speed and tension) and tape edge quality of factory-slit tapes on tape guiding are evaluated during short-term tests. A lateral force measurement technique is used to measure the force exerted by the tape edge on the guide flange. A technique for the lateral tape motion measurement is used to study the effect of continuous sliding on tape guiding. Wear tests up to 5000 cycles are conducted and coefficient of friction and lateral tape motion are monitored to study the effect of drive operating conditions (speed and tension), edge quality of factory-slit tapes and tape thickness on tape guiding. Optical microscopy, atomic force microscopy and scanning electron microscopy are employed to study and quantify the quality of tape edge

    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.

    2014-01-01

    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.

    A theoretical study of modes in circular hollow over-dimensioned waveguides is developed; it shows the interest of dielectric or weakly conducting wall guide use. An optical model computing the transmitted power of gaussian beams through these guides, for different types of walls, is established. The formulas obtained allow to optimize the guide and to adapt the beam. Applied to the EH 11 mode this optical model leads to new results. Systematical measurements of gaussian beam propagation in over-dimensioned guides are realised; they are concerned with beam power transmission, polarization, its structure and its radiation at the guide exit in function of the different characteristics of the beam and the guide [fr

    Ultrasonic guided waves have been widely utilized for long range inspection of structures. Especially, development of array guided waves techniques and its application for long range gas pipe lines(length of from hundreds meters to few km) were getting increased. In this study, focusing algorithm for array guided waves was developed in order to improve long range inspectability and accuracy of the array guided waves techniques for long range inspection of gas pipes, and performance of the developed techniques was verified by experiments using the developed array guided wave system. As a result, S/N ratio of array guided wave signals obtained with the focusing algorithm was increased higher than that of signals without focusing algorithm

  14. A Very Different Non-Stressful Comprehensive Final Exam that Achieve Our Goals for Student Evaluation and Learning

    Science.gov (United States)

    Bhavsar, Suketu

    2015-08-01

    I will introduce the radical concept of a final exam where the questions are given beforehand, a method I first encountered as a graduate student at Princeton University from an outstanding and well known astrophysicist and exceptional teacher, Lyman Spitzer.Every Instructor aspires for students to master all the material covered. A comprehensive final can assess the breadth and depth of their learning. Students are required to review early material in light of later topics, create connections and integrate understanding, thus retaining knowledge for the long term. Comprehensive finals can therefore be a significant basis for student learning and evaluation, but are especially daunting for non-STEM majors in required GE synthesis STEM classes. The exam format proposed here calmed student fears and encouraged thorough review.Ten days before the exam students received 20-30 challenging, well-crafted, numbered questions that interconnected and spanned the entire range of topics. The key is crafting questions that lead to deeply understanding the subject matter and mastering skills to solve problems. At the final, each student was required to pick a number out of a hat and answer that numbered question in a 5-minute presentation. They also had to critically comment on 10 other presentations of their peers. They are graded equally on both.The exam sets up definite goals for a student. Equally important, it enhances collaborative learning and peer mentoring. The conceptual questions and problems that students are required to answer can be studied together in study groups. The final presentation is theirs and they are not only encouraged but required to be constructively critical of their peer presentations.I will provide examples of some of the conceptual and problem solving questions I used. These were crafted to interconnect and span the entire range of topics. This method requires students to be prepared for all of the multitude of crafted question encouraging

    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.

    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.

    Park, Jung Chul; Cho, Youn Ho

    2000-01-01

    The guided wave mode conversion phenomena were investigated for the NDE of a plate-like structure with thickness variation. The ratios of reflection and transmission (R/T) were measured via the self-calibrating procedure which allows us to obtain experimental guided wave data in a more reliable way regardless of the coupling uncertainty between transducer and specimen. The results on R/T could be used to determine the thickness reduction of the structure. It was shown that not only the incident modes but also the converted ones need to be considered in the self-calibrating guided wave inspection to extract a reasonable correlation between experimental data and the thickness variation. Through this study, the potential of guided wave inspection as a quantitative NDE technique was explored based on the combined concept of self-calibration and multi-mode conversion in guided wave scattering problems

    Nonlinear guided waves have been investigated widely in simple geometries, such as plates, pipe and shells, where analytical solutions have been developed. This paper extends the application of nonlinear guided waves to waveguides with arbitrary cross sections. The criteria for the existence of nonlinear guided waves were summarized based on the finite deformation theory and nonlinear material properties. Numerical models were developed for the analysis of nonlinear guided waves in complex geometries, including nonlinear Semi-Analytical Finite Element (SAFE) method to identify internal resonant modes in complex waveguides, and Finite Element (FE) models to simulate the nonlinear wave propagation at resonant frequencies. Two examples, an aluminum plate and a steel rectangular bar, were studied using the proposed numerical model, demonstrating the existence of nonlinear guided waves in such structures and the energy transfer from primary to secondary modes.

    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.

    Nondestructive testing of composite panels benefit from the relatively long range propagation of guided waves in sandwich structures. The guided waves are sensitive to delamination, air bubbles inclusions and cracks and can thus bring information about hidden defects in the composite panel. The preliminary data in all such inspections is represented by the dispersion curves, representing the dependency of the phase/group velocity on the frequency for the propagating modes. In fact, all modes are more or less attenuated, so it is even more important to compute the dispersion curves, which provide also the modal attenuation as function of frequency. Another important aspect is the sensitivity of the dispersion curves on each of the elastic constant of the composite, which are orthotropic in most cases. All these aspects are investigated in the present work, based on our specially developed finite element numerical model implemented in Comsol, which has several advantages over existing methods. The dispersion curves and modal displacements are computed for an example of composite plate. Comparison with literature data validates the accuracy of our results.

    [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.

  17. Exams? Why worry? Interpreting anxiety as facilitative and stress appraisals.

    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.

    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

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.

    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.

    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.

    This study aimed to investigate video-guided laryngoscopy for nasogastric tube placement. This was an observational comparative study performed in a hospital. The participants included volunteers from the medical staff (physicians and nurses) experienced with nasogastric intubation, and non-medical staff (medical students, pharmacists and emergent medical technicians) with knowledge of nasogastric intubation but lacking procedural experience. Medical and non-medical hospital staff performed manual, laryngoscope-assisted and video-guided laryngoscope nasogastric intubation both in the presence and in the absence of an endotracheal tube, using a manikin. Nasogastric intubation times were compared between groups and methods. Using the video-guided laryngoscope resulted in a significantly shorter intubation time compared to the other 2 methods, both with and without an endotracheal tube, for the medical and non-medical staff alike (all p guided laryngoscope without endotracheal intubation, direct laryngoscope with endotracheal intubation and video-guided laryngoscope with endotracheal intubation compared to manual intubation without endotracheal intubation (0.49, 0.63 and 0.72 vs. 5.63, respectively, p ≤ 0.008). For non-medical staff, nasogastric intubation time was significantly shorter using video-guided laryngoscope without endotracheal intubation, direct laryngoscope with endotracheal intubation and video-guided laryngoscope with endotracheal intubation compared to manual intubation without endotracheal intubation (1.67, 1.58 and 0.95 vs. 6.9, respectively, p ≤ 0.002). And mean nasogastric intubation time for video-guided laryngoscope endotracheal intubation was significantly shorter for medical staff than for non-medical staff (0.49 vs. 1.67 min, respectively, p = 0.041). Video-guided laryngoscope reduces nasogastric intubation time compared to manual and direct laryngoscope intubation, which promotes a consistent technique when performed by

    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. 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.

    An optical guide, which is a light guide located between NaI(Tl) scintillation-crystal and array of photo-multiplier tubes (PMTs) in the gamma camera detector system, is an essential component to deliver the spatial information recorded in scintillator to the PMTs. Without the optical guide, the spatial information within the range of a single PMT could not be obtained. For the design of the optimal optical guide, it is necessary to characterize its properties, especially sensitivity and spatial resolution of detector. In this study, the thickness and the refractive index of optical guide, which affect not only on the sensitivity but also on the spatial resolution of gamma-camera detector, were investigated by using Monte Carlo simulation. A 12'x12'x3/8' NaI(Tl) and 23 PMTs with each 5' diameter were considered as a gamma-camera detector components. Interactions of optical photons in the scintillator and the optical guide were simulated using a commercial code DETECT97, and the spatial resolution, mainly interfered by the intrinsic inward distortion within the PMT, was investigated using our own ANGER program, which was developed to calculate positions of incident photons in the gamma camera. From the simulation results, it was found that an optical guide with 1.6 of refractive index and 10 mm of thickness give maximum sensitivity and minimum spatial distortion, respectively

    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.

    Peer reviews are a standard co-operative OECD working tool that offer member countries a framework to compare experiences and examine best practices in a host of areas. The OECD Nuclear Energy Agency (NEA) has developed a proven methodology for conducting peer reviews in radioactive waste management and nuclear R and D. Using this methodology, the NEA Radioactive Waste Management Committee's Working Party on Decommissioning and Dismantling (WPDD) developed the present guide as a framework for decommissioning cost reviewers and reviewees to prepare for and conduct international peer reviews of decommissioning cost estimate studies for nuclear facilities. It includes checklists that will help national programmes or relevant organisations to assess and improve decommissioning cost estimate practices in the future. This guide will act as the NEA reference for conducting such international peer reviews. The remainder of this guide is divided into eight chapters. Chapter 2 describes gathering the cost estimate study and underpinning documents, reviewing the study and writing a final report. Chapter 3 provides a detailed checklist approach for the review of the cost study report. Chapter 4 provides checklists to assist in reviewing benchmarked information. Chapter 5 provides comments on the approach and recommendations for use of this guide. Chapters 6 and 7 provide the background material used in developing this guide and Chapter 8 provides a list of the abbreviations and acronyms used in this guide

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.

    Full Text Available Tem sido objeto de preocupação da literatura médica e, mais recentemente, da psicológica, a alta prevalência do câncer de mama nas mulheres. O diagnóstico precoce muito favorece na redução dos índices e, entre os meios de detecção, o "auto-exame da mama" se caracteriza como uma prevenção secundária, sem custos e segura. Pesquisas demonstram, contudo, que a prática do auto-exame da mama é insatisfatória, principalmente em mulheres de escolaridade e nível sócio-econômico baixos. Segundo a Teoria da Ação Racional (TRA, a maioria dos comportamentos humanos pode ser explicada em termos de crenças comportamentais ou normativas. Nesse sentido, a presente pesquisa teve por objetivo investigar as crenças modais salientes desse estrato populacional, desprovido de informações claras e serviços de saúde efetivos, através de um levantamento em uma amostra de 40 mulheres entrevistadas em ambulatórios públicos de João Pessoa (PB. As entrevistas continham itens sobre as vantagens e desvantagens do auto-exame da mama, conhecimentos e dados sócio-demográficos. A média de idade da amostra foi de 32,5 anos (DP = 11,37. As entrevistas indicaram um total de 132 crenças comportamentais, que foram categorizadas em nove dimensões e 166 crenças normativas, categorizadas em quatro dimensões. Estes resultados demonstraram que as crenças influenciam a adesão à prática do auto-exame da mama e servirão de base para que os profissionais que lidam com campanhas públicas de prevenção voltem sua atenção para esses aspectos e abordem conteúdos que promovam não só a prática do auto-exame da mama, mas outras estratégias preventivas nesta significativa população.It has been object of concern to the medical literature and, more recently, to psychology, the high prevalence of breast cancer in women.

    Full Text Available Clearance gaps between guide vanes and cover plates of Francis turbines tend to increase in size due to simultaneous effect of secondary flow and erosion in sediment affected hydropower plants. The pressure difference between the two sides of the guide vane induces leakage flow through the gap. This flow enters into the suction side with high acceleration, disturbing the primary flow and causing more erosion and losses in downstream turbine components. A cascade rig containing a single guide vane passage has been built to study the effect of the clearance gap using pressure sensors and PIV (Particle Image Velocimetry technique. This study focuses on developing a numerical model of the test rig, validating the results with experiments and investigating the behavior of leakage flow numerically. It was observed from both CFD and experiment that the leakage flow forms a passage vortex, which shifts away from the wall while travelling downstream. The streamlines contributing to the formation of this vortex have been discussed. Furthermore, the reference guide vane with symmetrical hydrofoil has been compared with four cambered profiles, in terms of the guide vane loading and the consequent effect on the leakage flow. A dimensionless term called Leakage Flow Factor (Lff has been introduced to compare the performances of hydrofoils. It is shown that the leakage flow and its effect on increasing losses and erosion can be minimized by changing the pressure distribution over the guide vane.

    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 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.

    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.

    In order to study the desirable sign system that leads people to the proper evacuation behavior in the nuclear plant, an experiment was conducted by using 3D simulation of a part of the nuclear buildings. As the condition of the experiment, 3 different simulations on the type of guide signs and the height of installation were provided. Participants in the experiment were asked: to reach the emergency exit as quickly as possible in case of the imaginary fire, to report the signs utilized for finding the way during his evacuation, and to evaluate their comprehensibility to evaluate synthetically each installation and guide sings from the view point of comprehensibility. Synthetic evaluation was highly rated when we indicated the signs on the face of the floor additionally and installed the guide signs at a height of 1000mm above the floor. For the individual guide sign, it tended to evaluate mostly comprehensible that the pathway guide sign was installed at 1,000mm above the floor, though it did not reach a statistical significant level. Furthermore, the necessity was suggested to take into consideration on the spatial relationship between a moving person and the guide signs. (author)

    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}.

    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

    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). Exam-related beta-blocker use was associated with an increased risk of antidepressant use (adjusted HRs, 1.68 [95% confidence intervals (CIs), 1.57-1.79], p beta-blockers during the exam period was

  17. A Study on Elastic Guided Wave Modal Characteristics in Multi-Layered Structures

    In this study, we have developed a program which can calculate phase and group velocities, attenuation and wave structures of each mode in multi-layered plates. The wave structures of each mode are obtained, varying material properties and number of layers. The key in the success of guided wave NDE is how to optimize the mode selection scheme by minimizing energy loss when a structure is in contact with liquid. In this study, the normalized out-of-plane displacements at the surface of a free plate are used to predict the variation of modal attenuation and verily the correlation between attenuation and wave structure. It turns out that the guided wave attenuation can be efficiently obtain from the out-of-plane displacement variation of a free wave guide alleviating such mathematical difficulties in extracting complex roots for the eigenvalue problem of a liquid loaded wave guide. Through this study, the concert to optimize guided wave mode selection is accomplished to enhance sensitivity and efficiency in nondestructive evaluation for multi-layered structures.

  18. A computational fluid dynamics modeling study of guide walls for downstream fish passage

    Mulligan, Kevin; Towler, Brett; Haro, Alexander J.; Ahlfeld, David P.

    2017-01-01

    A partial-depth, impermeable guidance structure (or guide wall) for downstream fish passage is typically constructed as a series of panels attached to a floating boom and anchored across a water body (e.g. river channel, reservoir, or power canal). The downstream terminus of the wall is generally located nearby to a fish bypass structure. If guidance is successful, the fish will avoid entrainment in a dangerous intake structure (i.e. turbine intakes) while passing from the headpond to the tailwater of a hydroelectric facility through a safer passage route (i.e. the bypass). The goal of this study is to determine the combination of guide wall design parameters that will most likely increase the chance of surface-oriented fish being successfully guided to the bypass. To evaluate the flow field immediately upstream of a guide wall, a parameterized computational fluid dynamics model of an idealized power canal was constructed in © ANSYS Fluent v 14.5 (ANSYS Inc., 2012). The design parameters investigated were the angle and depth of the guide wall and the average approach velocity in the power canal. Results call attention to the importance of the downward to sweeping flow ratio and demonstrate how a change in guide wall depth and angle can affect this important hydraulic cue to out-migrating fish. The key findings indicate that a guide wall set at a small angle (15° is the minimum in this study) and deep enough such that sweeping flow dominant conditions prevail within the expected vertical distribution of fish approaching the structure will produce hydraulic conditions that are more likely to result in effective passage.

    Full Text Available Introduction: Test -anxiety is one of the most common mental health problems among the students that can impair performance and leads to failure of the exam. So, this study aimed to determine the rate of exam-anxiety among Kermanshah University of Medical Sciences' students. Methods: This cross sectional-analytic study was conducted on 510 students of Kermanshah University of Medical Sciences by convenience sampling method in 2014. In this study, data collection tool was Test-Anxiety questionnaire includes 25 questions. Data were analyzed with the Pearson correlation and t-test using SPSS 16 software. Results: 198 students (38. 8% had mild exam-anxiety, 140 students (27. 5% moderate exam-anxiety and 172 students (33. 7% had severe exam-anxiety. The difference between the mean of anxiety scores was significant at various fields of study (P <0. 05.  Midwifery students experienced more stress in comparison with the students of other fields. There was a significant relationship between exam anxiety level, and the variables of gender, location, age and total grades average of students (P<0/05. There was not a significant relationship between exam anxiety level and marital status, parental occupation, semester entrance and employment of students. Conclusion: Due to the high level of exam anxiety among the different fields of medicine as well as the negative effect of this type of anxiety on academic performance of students, the necessity of the use of psychological services, counseling, identification of causes of anxiety, and planning for decreasing this problem was recommended. Obviously, in this regard, more attention should be paid to the highest-risk groups such as female midwifery students.

    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.

    2011-01-01

    In this Letter, both in-plane and out-of-plane guided waves in a thin plate with local resonators are studied numerically and experimentally. Through the numerical simulation, a new metamaterial plate design is achieved for a low-frequency bandgap in both in-plane and out-of-plane guided waves. Experiments were conducted to validate the numerical design. In the experiment, piezoelectric transducers were used to generate and receive guided wave signals. The results show that the numerical predictions are in very good agreement with the experimental measurements. Specifically, the connection between the local resonance in the thin plate and its wave attenuation mechanism was discussed. -- Highlights: → Both in-plane and out-of-plane guided waves in a thin plate with local resonators are studied numerically and experimentally. → A new metamaterial plate design is achieved for a low-frequency bandgap in both in-plane and out-of-plane guided waves. → Experiments were conducted to validate the numerical design. → The connection between the local resonance in the thin plate and its wave attenuation mechanism was investigated.

    National Exam level of schooling is implemented by the Ministry of Education and Culture for the development of education in Indonesia. The national examinations are centrally evaluated by the National Education Standards Agency, and the expected implementation of the national exams can describe the successful implementation of education at the district, municipal, provincial, or national level. In this study, we evaluate, analyze, and explore the implementation of the national exam database of the results of the Junior High School in 2014, with the Junior High School (SMP/MTs) as the smallest unit of analysis at the district level. The method used in this study is a data mining approach using the methodology of Knowledge Discovery in Databases (KDD) using descriptive analysis and spatial mapping of national examinations. The results of the classification of the data mining process to national exams of Junior High School in 2014 using data 6,878 SMP/MTs in West Java showed that 81.01 % were at moderate levels. While the results of the spatial mapping for SMP/MTs in West Java can be explained 36,99 % at the unfavorable level. The evaluation results visualization in graphic is done using ArcGIS to provide position information quality of education in municipal, provincial or national level. The results of this study can be used by management to make decision to improve educational services based on the national exam database in West Java. Keywords: KDD, spatial mapping, national exam.

    To assess test anxiety levels and related factors among students preparing for university 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.

  16. Study of guided wave transmission through complex junction in sodium cooled reactor

    Elie, Q.; Le Bourdais, F.; Jezzine, K.; Baronian, V.

    2015-01-01

    Ultrasonic guided wave techniques are seen as suitable candidates for the inspection of welded structures within sodium cooled fast reactors (SFR), as the long range propagation of guided waves without amplitude attenuation can overcome the accessibility problem due to the liquid sodium. In the context of the development of the Advanced Sodium Test Reactor for Industrial Demonstration (ASTRID), the French Atomic Commission (CEA) investigates non-destructive testing techniques based on guided wave propagation. In this work, guided wave NDT methods are applied to control the integrity of welds located in a junction-type structure welded to the main vessel. The method presented in this paper is based on the analysis of scattering matrices peculiar to each expected defect, and takes advantage of the multi-modal and dispersive characteristics of guided wave generation. In a simulation study, an algorithm developed using the CIVA software is presented. It permits selecting appropriate incident modes to optimize detection and identification of expected flawed configurations. In the second part of this paper, experimental results corresponding to a first validation step of the simulation results are presented. The goal of the experiments is to estimate the effectiveness of the incident mode selection in plates. The results show good agreement between experience and simulation. (authors)

    Recently, CT-guided stereotactic surgery has become of major interest, and some authors have discussed its potential in functional neurosurgery. The following is a comparative study of the CT-guided stereotactic technique and the conventional roentogenographic stereotactic technique. The Brown-Roberts-Wells apparatus was used for both types of procedures. 37 stereotactic procedures were performed on 35 patients under local anesthesia; 16 for stereotactic biopsy and 21 for stereotactic functional neurosurgery. Target points for stereotactic biopsy were determined by the CT-guided technique and target points for functional neurosurgery were determined by the conventional roentogenographic technique. The correlation with the position of target point determined by both techniques was investigated in the 21 functional neurosurgical procedures. On these occasions the authors used the reformatted horizontal and sagittal CT through the anterior and posterior commissure to determine the position of target point by the CT-guided technique. Results: It was found that the AC-PC line crossed with Reid's base line at angle of 11 ± 1 deg, and therefore it is important to obtain a CT images including AC-PC line at this angle. When applying the CT guided stereotactic procedure for functional surgery, it should be known that there could be a discrepancy within 2 mm from the conventional target determination. (author)

  18. The Experience of Being a Guide Dog Puppy Raiser Volunteer: A Longitudinal Qualitative Collective Case Study

    2014-12-01

    Full Text Available There are no published studies that consider the experiences of guide dog puppy raisers. As these people are volunteers, their continued willingness to participate in the training of dogs for assisting the vision impaired and blind is essential for the viability of guide dog schools around the world. Using a qualitative, longitudinal methodology, data were collected from nine guide dog puppy raisers at four time points: before receiving the puppy, one week, then three months after the puppy arrived, and 13 months after the puppy arrived (at which time all puppies had left the raisers. Participants reported more challenges than benefits in raising the puppies. Volunteering to be a guide dog puppy raiser may not be the pleasant experience that is anticipated when community members first offer their services. Understanding what it is like to be a puppy raiser and working towards ways in which to address problems is essential, given that, without volunteers to train and care for puppies, vision impaired and blind people would not have access to guide dogs.

    Positron-emission tomography (PET) and PET/CT (computed tomography) are becoming increasingly important for diagnosis and treatment of cancer. Clinically relevant changes can sometimes be seen on PET that are not seen on other imaging modalities. However, PET is not suitable for guiding biopsy as the images are not obtained in real-time. Therefore, our research group has begun developing a concept for PET/CT-guided interventional procedures. This paper presents the rationale for this concept, outlines our research plan, and includes an initial study to evaluate the relative sensitivity of CT and PET/CT in detecting suspicious lesions.

    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

    Full Text Available Major depression is among the most common and debilitating disorders worldwide, associated with large societal and individual costs. Effective treatments exist, but accessibility is scarce. Guided Internet-Based Cognitive Behavioral Therapy (guided iCBT is a promising approach to reach more people in need of help. In the present pilot study, we investigated the outcome of a guided iCBT program for mild and moderate depression when disseminated from Sweden to Norway. The guided iCBT intervention was implemented within a university-based outpatient clinic by six student therapists under supervision. Twenty-two participants with mild and moderate depression were included in the study. Large treatment effects were found for depressive symptoms, whereas small to medium effects were observed for anxiety symptoms. More than half (55% of the participants were classified as recovered at post-treatment and more than a third (41% at follow-up. No participants had a significant deterioration from pre- to post-treatment, but two reported a significant deterioration from post-treatment to 6-month follow-up. Benchmarking the present results against those reported in the four original Swedish studies, we found that the treatment effect in the Norwegian study was slightly higher at post-treatment and slightly lower at 6-month follow-up compared to the outcome in the Swedish studies. The results should be interpreted with caution, as our sample was small and had no control group.

    Aim: To develop an ultrasound-guided technique for radiofrequency (RF) cervical medial branch neurotomy and to validate the accuracy of this new method. Materials and methods: Five non-embalmed, fresh cadavers were used; three male and two female cadavers with a median age at death of 67.2 years (range 50-84 years). This study was conducted in two parts. First, two of the cadavers were used to define the sonographic target point for RF cervical medial branch neurotomy using high-resolution ultrasound (12 to 5 MHz). The needles were guided to five consecutive cervical medial branches in the cadavers under ultrasound guidance. Subsequently, the position of the ultrasound-guided needle was verified using C-arm fluoroscopy. Ultrasound-guided RF neurotomy was performed to the C5 medial branches in all five cadavers. In the three cadavers not used in the first part of the study, ultrasound-guided RF neurotomy without C-arm fluoroscopic confirmation was performed to the C3-C7 medial branches. The accuracy of neurotomy was assessed by pathological examination of the cervical medial branches obtained through cadaver dissection. Results: In all five cadavers, the sonographic target point was identified in all C3-C7 segments with the 12 to 5 MHz linear transducer. In all 20 needle placements for the first and second cadavers, C-arm fluoroscopy validated proper needle tip positions. In all five cadavers, successful neurotomy was pathologically confirmed in 30 of 34 cervical medial branches. Conclusions: Ultrasound-guided cervical medial branch neurotomy was successfully performed in 30 of 34 cervical medial branches in five cadavers. However, before eliminating fluoroscopic validation of final needle tip positioning, the technique should be validated in symptomatic patients

    Full text: Recently we reported experiments in which slow highly charged ions are transmitted through nanocapillaries of 100nm diameter in an insulating PET foil of 10μm thickness [1]. The results of this work differ significantly from previous studies, which have been focused on capillaries in metals [2]. We measured the transmission of 3 keV Ne 7+ ions through the capillaries and focused the attention on ions whose charge has not changed during the passage through the capillary. The observation that the angular distribution for PET has a peak maximum whose position is equal to the tilt angle indicates a guiding of the Ne 7+ ion within the capillary. This guiding shows that the inner walls of the capillaries are charged up in a self-organizing process and collisions with the surface are finally prevented. We studied the time evolution of the capillary guiding as well as dependencies on the tilt angle [3]. Our most recent measurements were focussed on the investigation of the energy dependency for the guiding of Ne 7+ through capillaries. The measurements were done in an energy range from 2 keV up to 10 keV.We measured higher guiding efficiency for lower energies consistent with a previously developed model, which predicted an increase of the guiding efficiency with decreasing projectile energy [3]. In addition we found the effect of a narrower width of the angular distribution of transmitted ions. This effect is also well described by the model. However, further work is needed to explain the amount of charges to build up the deflection field at the end of the capillaries

    This document provides the necessary foundation for establishing the strategy for the Prediction-Outcome studies currently being conducted by the ONKALO Modelling Task Force (OMTF) during the construction of the ONKALO ramp. These studies relate to the geology, rock mechanics, hydrogeology and hydrogeochemistry. The purpose of the Prediction-Outcome campaign currently underway in the ONKALO ramp tunnel is to optimize Posiva's ability to predict rock conditions ahead of the excavation face. The aim of the work is: to enhance confidence in ability to predict rock conditions in general - and especially for the repository volumes; (later) testing and verification of repository design rules as it would not be possible to make too many additional boreholes in repository volume; and to support the ongoing construction work and make possible the application of the CEIC method. The document also presents current plans for at what stages of the ONKALO construction predictions and outcome assessments will be made as well as current plans for what properties and impacts will be predicted. These plans will evidently be subject to revision during the course of the work. (orig.)

    2011-03-01

    In the present study, the benefit of moving teeth into extraction sockets preserved by a bone substitute was evaluated. This was performed to determine whether this was advantageous for orthodontic space closure. Socket preservation employing the bony alveolus in patients presenting the orthodontic indication for premolar extraction therapy was performed. Analogue premolars were extracted in a split-mouth design. One extraction alveolus was filled with a silica matrix-embedded, nanocrystalline hydroxyapatite bone substitute, with the other acting as a control. The orthodontic space was then closed using NiTi closed coil springs (200 g). Photographs and X-rays were acquired for documentation. Space closure succeeded without complications, e.g., root resorptions or inflammations. Gingival invaginations occurred in two of the control sites. A difference in the velocity of extraction space closure in one patient was also observed. Orthodontic tooth movement using this bone replacement material is possible according to these study results. This technique, thus, warrants further investigation in future clinical trials focusing on preventive means to reduce the development of gingival invaginations.

  19. Directional nonlinear guided wave mixing: Case study of counter-propagating shear horizontal waves

    Science.gov (United States)

    Hasanian, Mostafa; Lissenden, Cliff J.

    2018-04-01

    While much nonlinear ultrasonics research has been conducted on higher harmonic generation, wave mixing provides the potential for sensitive measurements of incipient damage unencumbered by instrumentation nonlinearity. Studies of nonlinear ultrasonic wave mixing, both collinear and noncollinear, for bulk waves have shown the robust capability of wave mixing for early damage detection. One merit of bulk wave mixing lies in their non-dispersive nature, but guided waves enable inspection of otherwise inaccessible material and a variety of mixing options. Co-directional guided wave mixing was studied previously, but arbitrary direction guided wave mixing has not been addressed until recently. Wave vector analysis is applied to study variable mixing angles to find wave mode triplets (two primary waves and a secondary wave) resulting in the phase matching condition. As a case study, counter-propagating Shear Horizontal (SH) guided wave mixing is analyzed. SH wave interactions generate a secondary Lamb wave mode that is readily receivable. Reception of the secondary Lamb wave mode is compared for an angle beam transducer, an air coupled transducer, and a laser Doppler vibrometer (LDV). Results from the angle beam and air coupled transducers are quite consistent, while the LDV measurement is plagued by variability issues.

    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

    To explore the use of over the counter (OTC) medicines among students during exams in Riyadh City, Kingdom of Saudi Arabia. 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.

    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.

    To compare the outcomes of wavefront-guided and wavefront-optimized treatment in fellow eyes of patients having laser in situ keratomileusis (LASIK) for myopia. Medical and Vision Research Foundation, Tamil Nadu, India. This prospective comparative study comprised 27 patients who had wavefront-guided LASIK in 1 eye and wavefront-optimized LASIK in the fellow eye. The Hansatome (Bausch & Lomb) was used to create a superior-hinged flap and the Allegretto laser (WaveLight Laser Technologie AG), for photoablation. The Allegretto wave analyzer was used to measure ocular wavefront aberrations and the Functional Acuity Contrast Test chart, to measure contrast sensitivity before and 1 month after LASIK. The refractive and visual outcomes and the changes in aberrations and contrast sensitivity were compared between the 2 treatment modalities. One month postoperatively, 92% of eyes in the wavefront-guided group and 85% in the wavefront-optimized group had uncorrected visual acuity of 20/20 or better; 93% and 89%, respectively, had a postoperative spherical equivalent refraction of +/-0.50 diopter. The differences between groups were not statistically significant. Wavefront-guided LASIK induced less change in 18 of 22 higher-order Zernike terms than wavefront-optimized LASIK, with the change in positive spherical aberration the only statistically significant one (P= .01). Contrast sensitivity improved at the low and middle spatial frequencies (not statistically significant) and worsened significantly at high spatial frequencies after wavefront-guided LASIK; there was a statistically significant worsening at all spatial frequencies after wavefront-optimized LASIK. Although both wavefront-guided and wavefront-optimized LASIK gave excellent refractive correction results, the former induced less higher-order aberrations and was associated with better contrast sensitivity.

    Guidelines for referral of children to general anesthesia (GA) to complete MRI studies are lacking. We devised a pediatric procedural sedation guide to determine whether a pediatric procedural sedation guide would decrease serious adverse events and decrease failed sedations requiring rescheduling with GA. We constructed a consensus-based sedation guide by combining a retrospective review of reasons for referral of children to GA (n = 221) with published risk factors associated with the inability to complete the MRI study with sedation. An interrupted time series analysis of 11 530 local sedation records from the Pediatric Sedation Research Consortium between July 2008 and March 2013, adjusted for case-mix differences in the pre- and postsedation guide cohorts, evaluated whether a sedation guide resulted in decreased severe adverse events (SAE) and failed sedation rates. A significant increase in referrals to GA following implementation of a sedation guide occurred (P pediatric procedural sedation services. © 2016 John Wiley & Sons Ltd.

  7. The study on nondestructive evaluation for a tubular structure by the lamb-type guided wave wedge

    1998-01-01

    The study on the cylindrical guided wave was carried out to investigate its feasibility for nondestructive evaluation of tubular structures such as heat exchanger tubings of power industries and various pipings of chemical plants. The concept of wedge design and incident angle selection to optimize guided wave generation is presented based on the dispersion theory and the snell's law for the cylindrical guided wave. The brass tubes with artificial defects in the circumferential or axial direction were used for detect defection experiments. It was found that guided wave sensitivity for detecting an axial defect can be remarkably improved by using non-axisymmetrically launched guided waves. Through this study, it is expected that the guided wave can be successfully applied to tubular structure inspections as an more advanced and efficient NDE technique than a conventional point-by-point technique.

O texto baseia-se numa pesquisa que incluiu uma observação dentro da redação da revista e análise de materiais impressos, centrando-se na forma como a revista aborda o corpo masculino e coloca a preocupação com a aparência como importante para uma masculinidade bem sucedida. Com base nestes dados busco avaliar, a partir de perspectivas feministas e sobre o corpo, a influência do valor dado ao corpo e ao seu monitoramento reflexivo na constituição de identidades de gênero.In this article I elaborate theoretical comments on the subject of corporeality and the new forms of experiencing the body that are present in contemporary times. 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.

    Guided-mode resonance in a diffraction band of multilayer dielectric gratings may lead to a catastrophic result in laser system, especially in the ultrashort pulse laser system, so the inhibition of guided-mode resonance is very important. In this paper the characteristics of guided-mode resonance in multilayer dielectric grating are studied with the aim of better understanding the physical process of guided-mode resonance and designing a broadband multilayer dielectric grating with no guided-mode resonance. By employing waveguide theory, all guided-wave modes appearing in multilayer dielectric grating are found, and the incident conditions, separately, corresponding to each guided-wave mode are also obtained. The electric field enhancement in multilayer dielectric grating is shown obviously. Furthermore, from the detailed analyses on the guided-mode resonance conditions, it is found that the reduction of the grating period would effectively avoid the appearing of guided-mode resonance. And the expressions for calculating maximum periods, which ensure that no guided-mode resonance occurs in the requiring broad angle or wavelength range, are first reported. The above results calculated by waveguide theory and Fourier mode method are compared with each other, and they are coincident completely. Moreover, the method that relies on waveguide theory is more helpful for understanding the guided-mode resonance excited process and analyzing how each parameter affects the characteristic of guided-mode resonance. Therefore, the effects of multilayer dielectric grating parameters, such as period, fill factor, thickness of grating layer, et al., on the guided-mode resonance characteristic are discussed in detail based on waveguide theory, and some meaningful results are obtained.

    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.

    Managing incivility in academic settings is among the basic concerns and challenges of most educational systems, including nursing education. Incivility management cannot be considered devoid of disruptive behaviors. However, incivility management is a complexphenomenon upon which few studies are conducted. The present study aims at discovering teachers and students' experiences regarding incivility and developing an approach to manage nursing students' incivility. The present study was conducted based on the qualitative research design of the grounded theory methodology. This study was conducted at schools of nursing in academic settings in Iran. Study participants in the present study include nurse teachers (N=20) and nursing students (N=9). In-depth semi-structured interviews were conducted using theoretical and purposive sampling. Constant comparative analysis was used for data analysis. The results include four main categories; (1) deterioration of learning; (2) dominant individual and organisational culture; (3) guided democracy; and (4) movement toward professionalism. Guided democracy is recognised as the main basic psychosocial process for incivility management. Incivility management is pursued to help learners develop professional performance. As indicated by the results of the present study, guided democracy is an effective strategy for incivility management in nursing education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Before starting a new animal experiment, thorough analysis of previously performed experiments is essential from a scientific as well as from an ethical point of view. The method that is most suitable to carry out such a thorough analysis of the literature is a systematic review (SR). An essential first step in an SR is to search and find all potentially relevant studies. It is important to include all available evidence in an SR to minimize bias and reduce hampered interpretation of experimental outcomes. Despite the recent development of search filters to find animal studies in PubMed and EMBASE, searching for all available animal studies remains a challenge. Available guidelines from the clinical field cannot be copied directly to the situation within animal research, and although there are plenty of books and courses on searching the literature, there is no compact guide available to search and find relevant animal studies. Therefore, in order to facilitate a structured, thorough and transparent search for animal studies (in both preclinical and fundamental science), an easy-to-use, step-by-step guide was prepared and optimized using feedback from scientists in the field of animal experimentation. The step-by-step guide will assist scientists in performing a comprehensive literature search and, consequently, improve the scientific quality of the resulting review and prevent unnecessary animal use in the future.

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.

    Compare the effectiveness of ultrasound and fluoroscopy to guide intra-articular injections (IAI) in selected cases. A prospective study in our outpatient clinics at the Rheumatology Division at Universidade Federal de São Paulo (UNIFESP), Brazil, was conducted to compare the short-term (4 weeks) effectiveness of ultrasound and fluoroscopy-guided IAI in patients with rheumatic diseases. Inclusion criteria were: adults with refractory synovitis undergoing IAI with glucocorticoid. All patients had IAI performed with triamcinolone hexacetonide (20mg/ml) with varying doses according to the joint injected. A total of 71 rheumatic patients were evaluated (52 women, 44 whites). Mean age was 51.9 ± 13 years and 47 of them (66.2%) were on regular DMARD use. Analysis of the whole sample (71 patients) and hip sub-analysis (23 patients) showed that significant improvement was observed for both groups in terms of pain (P < 0.001). Global analysis also demonstrated better outcomes for patients in the FCG in terms of joint flexion (P < 0.001) and percentage change in joint flexion as compared to the USG. Likert scale score analyses demonstrated better results for the patients in the USG as compared to the FCG at the end of the study (P < 0.05). No statistically significant difference between groups was observed for any other study variable. Imaging-guided IAI improves regional pain in patients with various types of synovitis in the short term. For the vast majority of variables, no significant difference in terms of effectiveness was observed between fluoroscopy and ultrasound guided IAI.

    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

    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

    A new version of our compact and lightweight patient-mounted MRI-compatible 4 degree-of-freedom (DOF) robot for MRI-guided arthrography procedures is introduced. This robot could convert the traditional two-stage arthrography procedure (fluoroscopy-guided needle insertion followed by a diagnostic MRI scan) to a one-stage procedure, all in the MRI suite. The results of a recent accuracy study are reported. A new mounting technique is proposed and the mounting stability is investigated using optical and electromagnetic tracking on an anthropomorphic phantom. Five volunteer subjects including 2 radiologists were asked to conduct needle insertion in 4 different random positions and orientations within the robot's workspace and the displacement of the base of the robot was investigated during robot motion and needle insertion. Experimental results show that the proposed mounting method is stable and promising for clinical application.

    1993-09-01

    Feasibility studies (FS) determine what remedial alternatives are presented to regulators for site cleanup. A key consideration in this process is the waste to be generated. Minimizing the volume and toxicity of this waste will ultimately contribute to the selection of the best remedial option. The purpose of this checklist guide is to assist the user in incorporating pollution prevention/waste minimization (PP/WM) in all FS phase projects of the Environmental Restoration (ER) Program. This guide will help users document PP/WM activities for technology transfer and reporting requirements. Automated computer screens will be created from the checklist data to assist users with implementing and evaluating waste reduction. Users can then establish numerical performance measures to measure progress in planning, training, self-assessments, field implementation, documentation, and technology transfer. Cost savings result as users train and assess themselves and perform preliminary waste assessments

    The condenser tube is examined by the eddy current test (ECT) method to identify the integrity of the nuclear power plant. Because ECT probe is moved through the tube inside to identify flaws, the ECT probe should be exchanged periodically due to the wear of probe surface in order to remove the noise form the ECT signal. Moreover, it is impossible to examine the tube by ECT method because the ECT probe can not move through the inside due to the deformation such as dent. Recently, the theory of guided wave was established and the equipment applying the theory has been actively developed so as to overcome the limitation of ECT method for the tube inspection of heater exchanger in nuclear power plant. The object of this study is to know the feasibility of applying the guided wave technique to condenser tube in NPP

    Charged-particle transport systems consisting of magnetic quadrupole lenses have been employed in recent years in the study of (n, charged particle) reactions. A new transport system was completed at the laboratory that is based both on magnetic lenses as well as electrostatic fields. The magnetic focusing of the charged-particle guide is provided by six magnetic quadrupole lenses arranged in a CDCCDC sequence (in the vertical plane). The electrostatic field is produced by a wire at high voltage which stretches the length of the guide and is physically at the centre of the magnetic axis. The magnetic lenses are used for charged particles above 5 MeV; the electrostatic guide is used for lower energies. This hybrid system possesses the excellent focusing and background rejection properties of other magnetic systems. For low energy charged-particles, the electrostatic transport avoids the narrow band-passes in charged-particle energy which are a problem with purely magnetic transport systems. This system is installed at the LLNL Cyclograaff facility for the study of (n, charged particle) reactions at neutron energies up to 35 MeV. (Auth.)

    The main purpose of this study is to investigate the best configuration between guide vanes and cross flow vertical axis wind turbine with variation of several parameters including guide vanes tilt angle and the number of turbine and guide vane blades. The experimental test were conducted under various wind speed and directions for testing cross flow wind turbine, consisted of 8, 12 and 16 blades. Two types of guide vane were developed in this study, employing 20° and 60° tilt angle. Both of the two types of guide vane had three variations of blade numbers which had same blade numbers variations as the turbines. The result showed that the configurations between 60° guide vane with 16 blade numbers and turbine with 16 blade numbers had the best configurations. The result also showed that for certain configuration, guide vane was able to increase the power generated by the turbine significantly by 271.39% compared to the baseline configuration without using of guide vane.

    Tuberculosis (TB) is one of the oldest infectious diseases in the world and still affects humanity today. Since 1993, the World Health Organization (WHO) considers TB as a global emergency. The clinical history of the individual, the serum exams and particularly, the imaging examination of the thorax, are used for diagnostic confirmation and monitoring of disease. TB is a chronic disease that usually evolves with pulmonary sequelae that must be monitored. The exam of the image more precise to assess the radiological patterns found in these patients is high-resolution computed tomography (HRCT), which aids in medical diagnosis and permit the determination of the area affected by radiological abnormalities of pulmonary tuberculosis. The best known of such modifications by means of exams or more accurate techniques is of extreme importance. Therefore, this study aimed to show the quantification, performed by algorithms, of the areas affected by the radiological abnormalities of TB through the HRCT, and compared with serum exams. We studied 16 patients with confirmed diagnosis of TB. The serum exams evaluated included: hemoglobin, hematocrit, albumin, speed hemo sedimentation and C-reactive protein. With the values of serum exams we observed that patients have anemia, low albumin levels and inflammatory activity, corroborating imaging exams, which show severe impairment of lung area due to the inflammation caused by disease activity.

    This study assessed the feasibility of telecytological evaluation of samples from CT-guided lung biopsies using a dynamic telecytological system in which the microscope was operated by personnel from the radiology department at the site of the biopsy and a cytologist off-site diagnosed the biopsy sample. 45 imprint samples from CT-guided biopsies of lung lesions were reviewed by two cytologists using a telecytological microscope (Olympus BX51, Tokyo, Japan). The telecytological microscope was operated by one radiologist and one radiology technician. The cytological samples were classified by a cytologist into four categories: benign, malignant, atypical cells of undetermined significance, and non-diagnostic. The results were compared with those of a previous consensus reading of two independent cytologists (gold standard). When the radiologist was operating the microscope, the diagnostic accuracy was 100% as both cytologists came to the correct diagnosis in all samples. When the technician operated the microscope, two diagnoses of cyotologist 1 differed from the gold standard. Thus, the accuracy for the technician was 95.56%. Telecytological evaluation of imprint samples from CT-guided lung biopsies is feasible because it can be performed with high diagnostic accuracy if personnel from the radiology department operate the microscope.
