  19. Modelling lead bioaccessibility in urban topsoils based on data from Glasgow, London, Northampton and Swansea, UK

    International Nuclear Information System (INIS)

    Appleton, J.D.; Cave, M.R.; Wragg, J.

    2012-01-01

    Predictive linear regression (LR) modelling between bioaccessible Pb and a range of total elemental compositions and soil properties was executed for the Glasgow, London, Northampton and Swansea urban areas in order to assess the potential for developing a national urban bioaccessible Pb dataset for the UK. LR indicates that total Pb is the only highly significant independent variable for estimating the bioaccessibility of Pb. Bootstrap resampling shows that the relationship between total Pb and bioaccessible Pb is broadly the same in the four urban areas. The median bioaccessible fraction ranges from 38% in Northampton to 68% in London and Swansea. Results of this study can be used as part of a lines of evidence approach to localised risk assessment but should not be used to replace bioaccessibility testing at individual sites where local conditions may vary considerably from the broad overview presented in this study. - Highlights: ► Total Pb is the only significant predictor for bioaccessible Pb in UK urban topsoils. ► Bootstrap resampling confirms relationship similar in four urban areas. ► Median bioaccessible fraction ranges from 38 to 68%. ► Results can be used for initial risk assessment in UK urban areas. - Total Pb is the only significant predictor for bioaccessible Pb in topsoils from four urban areas in the UK.

    Full Text Available As the United Kingdom's (UK first Ashoka U Changemaker Campus, the University of Northampton (UoN has embarked on a strategy that embraces social enterprises. Social enterprise, innovation and entrepreneurship are key competences that have been used by the university to address social inequalities. This paper will account for the social engagement challenges that are influential in the UK's higher educational environment. International perspectives will be highlighted to demonstrate that significant advantages can be obtained by borrowing and adapting policies and practice strategies. Our primary aims are: to showcase the fundamental activities of social responsibility as demonstrated by UoN and provide examples of stakeholder demands during periods of significant change. We argue that it is essential for higher education institutions (HEI to develop a more nuanced and innovative examination of community based initiatives and networks in order to sustain engagement and access.

    2017-03-01

    Full Text Available Attractive work has been defined as a job position which an individual wants, where the employee experiences job stability and where employee identification and dedication are fostered. The present study is aimed at increasing knowledge about attitude changes to work during young people’s transition from school to work-life. A closed cohort, consisting of 225 pupils from graduating classes in 10 upper secondary schools in Sweden, was studied. The most significant result was found in the pupils’ expectations regarding work attractiveness while they were still attending school and in the subsequent year, after they had finished school. During school attendance, there were no differences between the groups, while those who did not find employment after school greatly reduced their demands regarding attractive work.Those who managed to get a job maintained the same level of expectation as during their school years, in terms of requirements for an attractive job.

    Modin, Bitte; Låftman, Sara B.; Östberg, Viveca

    2017-01-01

    School ethos refers to the school leadership’s purposive efforts to shape and direct the attitudes, values and behaviors needed in order to promote an active learning environment and to prevent the emergence of undesirable behaviors by creating shared meaning and common goals for the school. The aim of this study was to examine how teacher rated aspects of school ethos are linked with manifestations of bullying among 11th grade students. Five teacher-rated sub-dimensions of school ethos (staff stability, teacher morale, structure-order, student focus, and academic atmosphere) were examined in relation to student-reported perpetration of and exposure to traditional school bullying and cyberbullying. The data material combines student and teacher information from two separate data collections performed in 2016, comprising teachers and students in 58 upper secondary schools in Stockholm. Analyses showed that bullying was associated with all but one of the five sub-dimensions of school ethos, namely structure and order for dealing with bullying behaviors at the school. Results are discussed in light of this counter-intuitive finding. Our findings nevertheless lend support to the idea that the social organization of schools, as reflected in their teacher-rated ethos, can affect individual students’ attitudes in a way that prevents the emergence of bullying behavior among students.

    Full Text Available School ethos refers to the school leadership’s purposive efforts to shape and direct the attitudes, values and behaviors needed in order to promote an active learning environment and to prevent the emergence of undesirable behaviors by creating shared meaning and common goals for the school. The aim of this study was to examine how teacher rated aspects of school ethos are linked with manifestations of bullying among 11th grade students. Five teacher-rated sub-dimensions of school ethos (staff stability, teacher morale, structure-order, student focus, and academic atmosphere were examined in relation to student-reported perpetration of and exposure to traditional school bullying and cyberbullying. The data material combines student and teacher information from two separate data collections performed in 2016, comprising teachers and students in 58 upper secondary schools in Stockholm. Analyses showed that bullying was associated with all but one of the five sub-dimensions of school ethos, namely structure and order for dealing with bullying behaviors at the school. Results are discussed in light of this counter-intuitive finding. Our findings nevertheless lend support to the idea that the social organization of schools, as reflected in their teacher-rated ethos, can affect individual students’ attitudes in a way that prevents the emergence of bullying behavior among students.

    The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three-year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, ) - particularly Conscientiousness and Neuroticism - were found to predict overall academic performance, after controlling for general intelligence. Results suggest that Conscientiousness, as measured at the age of 16, can explain change in academic performance at the age of 19. The effect of Neuroticism on Conscientiousness indicates that, as regarding getting good grades, it is better to be a bit neurotic than to be stable. The study extends previous work by assessing the relationship between the Big Five and academic performance over a three-year period. The results offer educators avenues for improving educational achievement. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available Context: In India, children of upper primary school receive less attention from health-care providers. The majority of their health problems are preventable through hygienic practices. Aims: The aim of this study was to find out the association of personal hygiene with common morbidities among upper primary school children. Settings and Design: A cross-sectional study conducted in a rural upper primary school of Odisha. Subjects and Methods: A semi-structured schedule based on the Global School Health Survey Questionnaire and necessary instruments for clinical examination were used. Statistical Analysis Used: Data were entered in Microsoft Excel 2007 and analyzed by SPSS version 20 software. Results: Of 90 participants, 58 (64.4% were girls. The mean age was 11.8 (±1.01 years. The mean body mass index of females was significantly higher than males (16.95 vs. 14.72; P = 0.001. More than 90% of children maintained good personal hygiene such as clean tongue, clean hair, handwashing, and using footwear. The most common morbidities found were dental caries (38.9%, history of worms in stool and lethargy (20%. A mean score of 6.14 ± 0.11 (out of 8 was seen for personal hygiene and not associated with any particular morbidity or gender. Brushing daily was significantly associated with reduced dental caries (χ2 = 8.7; P < 0.005 and foul-smelling breath (χ2 = 4.93; P < 0.05. Fungal infections were significantly less in children who bathed daily (χ2 = 28.7; <0.005 and wore clean clothes (χ2 = 5.06; P < 0.05. Conclusion: Dental caries, foul-smelling breath, and fungal infections were significantly associated with poor personal hygiene. School health services should also focus on upper primary school children for improvement of personal hygiene.

    2016-05-01

    Background: In developed countries, it is challenging for teachers to select pedagogical practices that encourage students to enrol in science and technology courses in upper secondary school. Purpose: Aiming to understand the enrolment dynamics, this study analyses sample-based data from Finland's National Assessment in Science to determine whether pedagogical approaches influence student intention to enrol in upper secondary school physics courses. Sample: This study examined a clustered sample of 2949 Finnish students in the final year of comprehensive school (15-16 years old). Methods: Through explorative factor analysis, we extracted several variables that were expected to influence student intention to enrol in physics courses. We applied partial correlation to determine the underlying interdependencies of the variables. Results: The analysis revealed that the main predictor of enrolment in upper secondary school physics courses is whether students feel that physics is important. Although statistically significant, partial correlations between variables were rather small. However, the analysis of partial correlations revealed that pedagogical practices influence inquiry and attitudinal factors. Pedagogical practices that emphasise science experimentation and the social construction of knowledge had the strongest influence. Conclusions: The research implies that to increase student enrolment in physics courses, the way students interpret the subject's importance needs to be addressed, which can be done by the pedagogical practices of discussion, teacher demonstrations, and practical work.

    Hernández-Rabanal, Carme; Vall, Aurora; Boter, Clara

    To explore whether training on strategies to identify and assess health-related information online has a positive impact on students' perception of their own eHealth literacy. The validated eHealth Literacy Scale (eHEALS) was administered to a sample of upper secondary school students, aged 15-18. One week later, they attended a training session on how to search and identify reliable health-related information and resources online. The eHEALS was administered again at the end of this session. Information about gender and school year was collected in both sessions. Perceived eHealth literacy was assessed by comparing the scores obtained before and after the session. Bivariate and multiple linear regressions were completed. Of the 298 students enrolled in upper secondary school (Bachillerato), 285 were included in the study. Approximately 52.28% (149) were female, and 47.72% (136) were male. The mean eHEALS score before the session was 24.19 (range: 8-40), and was 28.54 after it. The training was associated with higher perceived eHealth literacy scores (p <0,0001). Health literacy was positively associated with the usefulness and importance students give the Internet. Attendance at a training session on strategies to identify and assess health-related resources online is associated with higher levels of perceived eHealth literacy. Implementing specific training sessions on eHealth literacy in upper secondary school is a promising approach for enhancing students' eHealth literacy. Copyright © 2017 SESPAS.

    The aim of this study was to estimate the prevalence and correlates of mental disorders among upper primary school children in grades five through seven in Kenya. The Youth Self Report (YSR) instrument was adapted for use in Kenyan schools and administered to 2267 school children in grades five through seven from 23 randomly selected schools. We estimated the prevalence of DSM-IV mental disorders, and used logistic regression analyses to examine the socio-demographic factors associated with each disorder. The prevalence of any mental disorder among Kenyan school children was 37.7 % (95 % CI = 35.7-39.7 %). Somatic complaints were the most prevalent (29.6 %, 95 % CI = 27.8-31.5 %), followed by affective disorders (14.1 %, 95 % CI = 12.7-15.6 %) and conduct disorder (12.5 %, 95 % CI = 11.2-13.9). The presence of one or more comorbid mental disorder was seen among 18.2 % (95 % CI = 16.6-19.8 %) of children. Male sex, living in a peri-urban vs. rural area, being held back in school, having divorced or separated parents, and having an employed mother were associated with an increased likelihood of having most of the mental disorders examined, whereas increasing age was associated with a reduced likelihood. We observed a high prevalence of mental disorders among school children in Kenya. If not detected early, these disorders may interfere with children's psychological, social, and educational development. Our findings highlight the importance of implementing screening measures in schools that can detect single and multiple disorders in order to improve the mental health and well-being of the next generation.

    2014-08-01

    The Upper Quarter Y Balance Test (YBT-UQ) was developed as a way to identify upper extremity and trunk mobility in the open kinetic chain in the reaching limb as well as midrange limitations and asymmetries of upper extremity and core stability in the closed kinetic chain on the stabilizing limb. Performance on the YBT-UQ is similar between genders and between limbs; however, this has not been examined in athletes who participate in sports that result in upper extremity asymmetries. The primary purpose of this study is to determine if differences exist between the throwing vs. non-throwing sides in high-school baseball and softball athletes on the YBT-UQ. In order to complete this forty-eight male high school baseball players and seventeen female high school softball players were tested on the YBT-UQ. Reach distances were normalized to arm length (% AL). Comparisons were made between the throwing (T) and non-throwing (NT) arm for each direction as well as the composite score. No significant differences were observed between the T and NT arm for the medial (NT: 98.4 ± 8.6 %AL, T: 99.1 ± 8.6 %AL, p=0.42), inferolateral (NT: 90.8 ± 11.8 %AL, T: 90.3 ± 11.5 %AL, p =0.61), superolateral (NT: 70.6 ± 10.9 %AL, T: 70.4 ± 11.1 % AL, p=0.91) reaches, or the composite score (NT: 87.2 ± 8.9 % AL, T: 86.6 ± 8.1 %AL, p=0.72). Similarly, no differences were observed between the male baseball and female softball players (p=0.30-0.90). Based on these findings, it was concluded that there was no difference in performance on the YBT-UQ between throwing and non-throwing limbs in high school baseball and softball players. 3.

    2018-01-01

    In this paper we present results concerning how students in a Danish upper secondary school negotiate between sports culture and the prevailing norms of youth culture in a local school context. The study shows that it can be rather difficult for young people to combine sports culture with the local...... youth culture, because living a healthy and physically active life doesn’t fit very well with the prevailing norms of youth culture, which involve a dominant social arena characterized by parties and alcohol. By applying the figurational sociology of Norbert Elias, this article shows that being included...... in a sports figuration can result in exclusion from the youth figuration. Young athletic students are therefore in a constant process of negotiation, where they struggle to fit into both sport and non-sport related contexts, because it is important to belong within both. The study is based on 16 focus group...

  4. Solar Science Digital Comic Series that promotes Science Literacy with Upper Elementary and Middle School Students

    The SDO instruments (EVE, AIA and HMI) teams have created a digital comic book series for upper elementary and middle school students featuring solar science aficionados Camilla and Colours, 2 cool mascot characters. These comics may be printed or read on mobile devices and are available as a free download. Many teachers are looking for resources to use with their students via the IPad so our collaboration helps supply teachers with a great resource that teaches about solar concepts and helps dispel solar misconceptions. It doesn't come as a surprise to a lot of us, but a recent study confirms what's been theorized for years: Comics are a stronger learning tool than text books. Image-based storytelling is a powerful educational tool. Comics are probably more able to combine story and information simultaneously, more effectively and seamlessly, than almost any other medium. There's also a great potential to incorporate interactive elements into digital versions, so that more information can be presented on certain items on a page. For example, videos, animations and even historic footage and audio can be embedded into digital comics. Really, the possibilities are limited only by the creators' imaginations as to how to find new ways to create a rich experience that is interesting to explore for students. We are excited to unveil this new series of solar science comics that promotes science literacy with upper elementary and middle school students.

  5. The viability of alternative assessment methods in the Greek upper secondary school: the oral portfolio

    2012-02-01

    Full Text Available Τhe final examination of the English language subject, in the context of the Greek state upper secondary education, is a traditional paper-and-pencil test which does not include any assessment of oracy skills. This article explores the viability of the oral portfolio as an alternative assessment and pedagogic method that can facilitate the assessment of speaking and listening skills and create a more motivating learning environment. To this effect, three methodological tools were designed, namely, a questionnaire addressing upper secondary English teachers in Greek state schools, a case study involving an oral portfolio implementation and finally, a questionnaire for students to record their experience. The study demonstrates that implementation of the portfolio contributed to a successful assessment of oracy skills and that it was a stimulating experience for students. The results of the study also showed that the pedagogical value of the portfolio counterbalanced its practical constraints. The paper concludes by putting forward recommendations for the future application of this assessment technique in state school education.

    Full Text Available In this case study, we investigated teachers’ professional learning within a multinational project in an upper secondary school. The aim of the study was to investigate how the participating teachers adopted and applied the trialogical approach (TLA in their pedagogical practices and their challenges in doing that. The mixed method approach was used for data collection and analysis. About one-fourth of the teachers participated in the activities, ten females and three males. Three groups were identified, based on their activity in the project: pilot teachers, active adopters, and adopters. Altogether 79 students (38 males and 41 females answered a questionnaire concerning the pedagogical practices. The pedagogical revisions were well in line with TLA; the revised courses as well as new iterations and new ideas were indicators of the teachers’ creative implementation processes. However, some of the TLA ideas were more difficult to apply in an upper secondary school context; for example, the implementation of ideas involving cross-fertilization with other organizations and cultures was rare. In order to learn new pedagogical practices, teachers need organized time for collaborative planning, for reflecting, and for sharing.

    The multiple goal perspective posits that certain combinations of achievement goals are more favourable than others in terms of educational outcomes. This study aimed to examine longitudinally whether students' achievement goal profiles and transitions between profiles are associated with developments in self-reported and teacher-rated effort and academic achievement in upper elementary school. Participants were 722 fifth-grade students and their teachers in fifth and sixth grade (N = 68). Students reported on their achievement goals and effort in language and mathematics three times in grade 5 to grade 6. Teachers rated students' general school effort. Achievement scores were obtained from school records. Goal profiles were derived with latent profile and transition analyses. Longitudinal multilevel analyses were conducted. Theoretically favourable goal profiles (high mastery and performance-approach goals, low on performance-avoidance goals), as well as transitions from less to more theoretically favourable goal profiles, were associated with higher levels and more growth in effort for language and mathematics and with stronger language achievement gains. Overall, these results provide support for the multiple goal perspective and show the sustained benefits of favourable goal profiles beyond effects of cognitive ability and background characteristics. © 2017 The Authors.

  9. Role model and prototype matching: Upper-secondary school students’ meetings with tertiary STEM students

    Directory of Open Access Journals (Sweden)

    Eva Lykkegaard

    2016-04-01

    Full Text Available Previous research has found that young people’s prototypes of science students and scientists affect their inclination to choose tertiary STEM programs (Science, Technology, Engineering and Mathematics. Consequently, many recruitment initiatives include role models to challenge these prototypes. The present study followed 15 STEM-oriented upper-secondary school students from university-distant backgrounds during and after their participation in an 18-months long university-based recruitment and outreach project involving tertiary STEM students as role models. The analysis focusses on how the students’ meetings with the role models affected their thoughts concerning STEM students and attending university. The regular self-to-prototype matching process was shown in real-life role-models meetings to be extended to a more complex three-way matching process between students’ self-perceptions, prototype images and situation-specific conceptions of role models. Furthermore, the study underlined the positive effect of prolonged role-model contact, the importance of using several role models and that traditional school subjects catered more resistant prototype images than unfamiliar ones did.

    This study aimed to assess teachers' voice symptoms and noise in schools in Upper Egypt and to study possible differences between teachers in public and private schools. A cross-sectional analysis via questionnaire was carried out. Four schools were chosen randomly to represent primary and preparatory schools as well as public and private ones. In these schools, a total of 140 teachers participated in the study. They answered a questionnaire on vocal and throat symptoms and their effects on working and social activities, as well as levels and effects of experienced noise. Of all teachers, 47.9% reported moderate or severe dysphonia within the last 6 months, and 21.4% reported daily dysphonia. All teachers reported frequent feelings of being in noise, with 82.2% feeling it sometimes or always during the working day, resulting in a need to raise their voice. Teachers in public schools experienced more noise from nearby classes. The working conditions and vocal health of teachers in Upper Egypt, especially in public schools, are alarming.

    Teachers are professional voice users, always at high risk of developing voice disorders due to high vocal demand and unfavorable environmental conditions. This study aimed at identifying possible correlations between teachers' voice symptoms and their perception of noise, the location of schools, as well as the location and conditions of their classrooms. One hundred forty teachers (ages 21-56) from schools in Upper Egypt participated in this study. They filled out a questionnaire including questions about the severity and frequency of their voice symptoms, noise perception, and the location and conditions of their schools and classrooms. Questionnaire responses were statistically analyzed to identify possible correlations. There were significant correlations (P Egyptian schools.

  17. Swedish Upper Secondary School Students’ Conceptions of Negative Environmental Impact and Pricing

    Directory of Open Access Journals (Sweden)

    Cecilia Lundholm

    2013-03-01

    Full Text Available This study explores relationships between upper secondary school students’ understanding of prices and environmental impacts. The study uses responses from 110 students to problems in which they were asked to explain differences in prices and also to express and justify opinions on what should be the difference in prices. Very few students expressed an environmental dimension in their understanding of price. A few students suggested that environmental impact influenced price by raising demand for “Environmentally friendly products”. A few students suggested that ‘environmentally friendly products’ had higher prices because they were more costly to produce. We found no examples of students combining both lines of explanation. However, nearly half of the students believed that prices should reflect environmental effects, and this reasoning was divided between cases where the point was justified by a broad environmental motivation and cases where the point was justified in relation to incentives–to get consumers to act in a more environmentally friendly way.

    Full Text Available Abstract:Background: Anemia has been recognized as a major public health problem in developing countries. The magnitude of anemia among school children has received less attention compared with that in preschoolers and pregnant women. This study aimed to estimate the prevalence of anemia and to assess its associated factors among informal school children in rural Upper Egypt.Methods: A cross sectional descriptive study was conducted in a randomly selected Girls Education initiative schools in three Egyptian governorates for duration of 11 months. A structured questionnaire was used to collect sociodemographic data from 2826 children aged 6-19 years. Hemoglobin concentration and anthropometric indicators were assessed using the World Health Organization guidelines. Stool samples were examined for parasitic infestations, using the Kato Katz technique. The objective of the study was adequately explained to participants’ guardian and their consensus was obtained with assured confidentiality.Results: the prevalence of anemia among these children was 59.3%, out of which, 82.5% had mild anemia and 17.4% of them had moderate anemia. It was significantly higher among 64% of children in age group 6-9years and 61.3% of females.

    Myers, Heather; Poletti, Mary; Butler, Robert J

    2017-05-01

    The Upper Quarter Y-Balance Test (YBT-UQ) is a unique movement test where individuals perform at the limits of their stability, requiring the coordination of balance, proprioception, range of motion, and stabilization. It is not yet clear if performance on the YBT-UQ differs between sports with dissimilar emphasis on upper-extremity performance. To compare performance on the YBT-UQ between wrestlers, whose sport requires some degree of closed-chain activity, and baseball players, whose sport is primarily open kinetic chain in nature. Cross-sectional. High school preparticipation physical assessment. 24 healthy high school male wrestlers (mean age 16.12 ± 1.24 y) and 24 healthy high school male baseball players (mean age 15.79 ± 1.25 y). All subjects performed the YBT-UQ, which requires reaching in 3 directions while maintaining a push-up position. The variables of interest include the maximum reach in each direction, as well as the composite score. In addition, asymmetries between limbs for each reach direction were compared. Wrestlers performed significantly better than baseball players in the medial direction, inferolateral direction, and in composite scores. In the medial direction, wrestlers exhibited greater scores (P < .01) on both left and right limbs, 10.5 ± 10.2%LL and 9.95 ± 10.2%LL, respectively. Significant differences (P < .01) were also observed in the inferolateral direction, with a difference of 11.3 ± 12.0%LL on the left and 8.7 ± 11.0%LL on the right. Composite scores were higher (P < .01) for the wrestlers, with a difference of 7.0% on the left and 7.1% on the right. This study suggests that wrestlers perform better on the YBT-UQ than baseball players. The findings may suggest sport-specific normative data for the YBT-UQ in high school athletes.

    2017-01-01

    Full Text Available Across higher education institutions there has, for some time, been a growing move towards incorporation of the concepts of sustainability into the policies and practices of the organisations. Using the University of Northampton, in the United Kingdom as a case study, this project aimed to understand the efficacy of student engagement with a sustainability project called Planet Too. The study employed a range of methods including waste and energy audits, as well as questionnaire surveys both with students and landlords to examine their environmental attitudes, beliefs, and practices. The project was able to lead to increased awareness and engagement with the concepts of sustainability amongst the students. Recycling, though it was not one of the initiatives focused upon, was a key practice mentioned by both students and landlords. The engagement of the landlords was focused primarily on conservation of energy and water. However, conservation practices generally remained static, with limited significant or long-term changes in environmental practices. The key implications of the findings are discussed and recommendations suggested.

    We investigated the feasibility of using computer-assisted arm rehabilitation (CAAR) computer games in schools. Outcomes were children's preference for single player or dual player mode, and changes in arm activity and kinematics. Nine boys and two girls with cerebral palsy (6-12 years, mean 9 years) played assistive technology computer games in single-user mode or with school friends in an AB-BA design. Preference was determined by recording the time spent playing each mode and by qualitative feedback. We used the ABILHAND-kids and Canadian Occupational Performance Measure to evaluate activity limitation, and a portable laptop-based device to capture arm kinematics. No difference was recorded between single-user and dual-user modes (median daily use 9.27 versus 11.2 min, p = 0.214). Children reported dual-user mode was preferable. There were no changes in activity limitation (ABILHAND-kids, p = 0.424; COPM, p = 0.484) but we found significant improvements in hand speed (p = 0.028), smoothness (p = 0.005) and accuracy (p = 0.007). School timetables prohibit extensive use of rehabilitation technology but there is potential for its short-term use to supplement a rehabilitation program. The restricted access to the rehabilitation games was sufficient to improve arm kinematics but not arm activity. Implications for Rehabilitation School premises and teaching staff present no obstacles to the installation of rehabilitation gaming technology. Twelve minutes per day is the average amount of time that the school time table permits children to use rehabilitation gaming equipment (without disruption to academic attendance). The use of rehabilitation gaming technology for an average of 12 minutes daily does not appear to benefit children's functional performance, but there are improvements in the kinematics of children's upper limb.

    2013-08-01

    This study tested a theoretical model considering students' personality traits as predictors of student-teacher relationship quality (closeness, conflict, and dependency), the effects of student-teacher relationship quality on students' math and reading achievement, and the mediating role of students' motivational beliefs on the association between student-teacher relationship quality and achievement in upper elementary school. Surveys and tests were conducted among a nationally representative Dutch sample of 8545 sixth-grade students and their teachers in 395 schools. Structural equation models were used to test direct and indirect effects. Support was found for a model that identified conscientiousness and agreeableness as predictors of close, nonconflictual relationships, and neuroticism as a predictor of dependent and conflictual relationships. Extraversion was associated with higher levels of closeness and conflict, and autonomy was only associated with lower levels of dependency. Students' motivational beliefs mediated the effects of dependency and student-reported closeness on reading and math achievement. Copyright © 2013 Society for the Study of School Psychology.

    Prolonged sitting and psychosocial factors have been associated with musculoskeletal symptoms among adolescents. However, the impact of prolonged static sitting on musculoskeletal pain among South African high school students is uncertain. A prospective observational study was performed to determine whether sitting postural alignment and psychosocial factors contribute to the development of upper quadrant musculoskeletal pain (UQMP) in grade ten high school students working on desktop computers. The sitting postural alignment, depression, anxiety and computer use of 104 asymptomatic students were measured at baseline. At three and six months post baseline, the prevalence of UQMP was determined. Twenty-seven students developed UQMP due to seated or computer-related activities. An extreme cervical angle (43.95 degrees; OR 2.8; 95% CI: 1.1-7.3) and a combination of extreme cervical and thoracic angles (71.1 degrees; OR 2.2; 95% CI: 1.1-5.6) were significant postural risk factors for the development of UQMP. Boys with any extreme angle were more likely to suffer pain compared with boys with all middle range angles (OR 4.9; 95% CI: 1.0-24.5). No similar effect was found for girls. There was no strong relationship between depression, anxiety, computer exposure and UQMP among South African high school students.

    2008-01-01

    This paper examines the transmission patterns of Eastern Brittany's Romance language variety, Gallo, based on quantitative data showing learning patterns of school pupils of the language and their parents in 2003 and 2004. Results confirm the sharp decline in Gallo transmission between generations...... learning patterns of Gallo also demonstrate how they may be representative of a rupture with a greater and more stable use of Gallo in the past. Data also indicate that of those parents who do play a transmission role, there are fewer females than in previous generations. The school system has become...... a vital player in Gallo's revitalisation and it is, to some degree, brought out of its rural familial environment. However, Gallo is but an optional subject and in the context of issues raised by RLS theory, the decreasing trigenerational transmission pattern means that current revitalisation activity...

  19. General relativity in upper secondary school: Design and evaluation of an online learning environment using the model of educational reconstruction

    Because of its abstract nature, Albert Einstein's theory of general relativity is rarely present in school physics curricula. Although the educational community has started to investigate ways of bringing general relativity to classrooms, field-tested educational material is rare. Employing the model of educational reconstruction, we present a collaborative online learning environment that was introduced to final year students (18-19 years old) in six Norwegian upper secondary physics classrooms. Design-based research methods guided the development of the learning resources, which were based on a sociocultural view of learning and a historical-philosophical approach to teaching general relativity. To characterize students' learning from and interaction with the learning environment we analyzed focus group interviews and students' oral and written responses to assigned problems and discussion tasks. Our findings show how design choices on different levels can support or hinder understanding of general relativity, leading to the formulation of design principles that help to foster qualitative understanding and encourage collaborative learning. The results indicate that upper secondary students can obtain a qualitative understanding of general relativity when provided with appropriately designed learning resources and sufficient scaffolding of learning through interaction with teacher and peers.

  20. Coteaching with senior students – a way to refine teachers' PCK for teaching chemical bonding in upper secondary school

    Schultze, Felix; Nilsson, Pernilla

    2018-04-01

    During the last decade there has been on-going discussions about students' declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers' and students' different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students' frames of references. The teachers' PCK was refined which in turn lead to improved teaching strategies.

    Full Text Available Abstract Background Education is closely associated with health. Non-completion of upper secondary school influences academic achievement, employment, income and personal well-being. The purpose of the study is to explore predictors of non-completion of upper secondary school among female and male young adults in relation to mental health and educational factors in a socio-cultural, Arctic context. Methods The Norwegian Arctic Adolescent Health Study (NAAHS is a cross-sectional, school-based survey that was conducted in 2003–2005. Eighty-three percent of the population of 5,877 10th graders participated; 49.1%females, 450 reported indigenous Sami ethnicity, and 304 reported Laestadian affiliation. Data from NAAHS were merged with registry data from the National Education Database (NUDB Norway for 3,987 adolescents who gave their consent for follow-up studies. Results Non-completion of upper secondary school was 36.9 % among females and 36.6 % among males. Among females, predictors for non-completion were related to mental health symptoms, and among males, to residency in the northernmost and remote areas and self-reported functional difficulties at school, home and in leisure activities due to mental health problems. There was marginal significance between ethnicity and non-completion of upper secondary school, measured at 41.3 % for Sami and 36.8 % for non-Sami, respectively. Conclusions The gender differences found in this study emphasize the need for gender-specific interventions in preventing non-completion of upper secondary school. There is a need to recognize and treat extensive pro-social behaviour and social problems in young females. Young males from remote areas and those who in early adolescence struggle with functional impairment due to mental health problems need early interventions in lower secondary school.

    Many papers have emphasized the need for and importance of particular examples and the underlying rationale for introducing a historical dimension in mathematics education. This article presents the development and implementation of a project, based on original sources, in a situation where the existing curriculum does not include history. The subject was conic sections and the motivating problems and original work which eventually found resolution in modern concepts. The project was carried out during the school year 2006-2007 with 18 students of a Greek experimental high school 2nd class (11th degree). It was devised as a series of worksheets, separate readings and oral presentations and written essays so that students might appreciate that mathematics evolves under the influence of factors intrinsic and extrinsic to it. Both epistemological and disciplinary issues are taken into account. Even though this work is just one case study, we have found that exposing students directly to primary sources in mathematics contributes greatly to motivation and understanding, and illustrates the nature of mathematics as a discipline and as a human endeavour.

    Full Text Available Background: Teeth, apart from their physiologic function, play an important role in general appearance of indivduals. Therefore any disorder in their growth and evolution, will cause psychologic, social and even economic problems for the person. This observational cross- sectional study aimed to investigate relationship between dental occlusal patterns and obstructive nasal-upper airway- diseases. Methods: This study was perfromed in schools of No.4 Education at district of Isfahan in educational year 1381-82 between 607 students (277 male, 330 female aged 9-12 years old. Results of accurate ENT and dentistry physical examination were registered and analyzed using SPSS software and Chi-square and Mantel - Hanzel test. Results: With increasing age, The frequency of abnormal occlusal patterns increases (from 45.5% to 68.2% in males and 25.8% to 48.5% in females, p=0.015. The increasing in degree of palatal tonsilar hypertrophy was related to higher frequency of abnormal occlusal patterns (36.7% in +1 tonsilar hypertrophy, and 70% in +4 tonsilar hypertrophy, p=0.02. Also, history of frequent common colds, and history of previous nasal fractures were related with abnormal patterns [58.9% (p=0.032, and 83.4% (p= 0.043%, respectively].Five other parameters including sinusitis, hypertrophy of nasal turbinates, rhinitis, nasal polyposis and nasal septal deviation were not associated with abnormal occlusal patterns (p>0.1. Conclusion: Some of obstructive upper airwacy diseases are related with abnormal dental occlusal patterns. These parameters can be simply diagnosed, treated or prevented. Key words: dental occlusion, malocclusion, obstructive nasal disorders, nasal turbinates, adenoid, rhinitis, tonsillectomy, open mouth breathing

To examine the prevalence of selected risk factors for atherosclerosis: overweight, tobacco smoking, low physical activity, psychological distress and type A personality (characterized by tenseness, impatience, competitiveness, and aggressiveness) in adolescents and to assess the frequency the coexistence of risk factors (≥3) in relation to gender, age and school type. A cross-sectional study was carried out in a representative sample of youth aged 16 and 18 years (N=2983) in 8 voivodeships in Poland. The frequency of five atherosclerosis risk factors and their coexistence (≥3) was examined using self-reported questionnaires, in relation to gender, age and school type. Logistic regression analyses were used to assess the influence of the variables (gender, age and school type) on odds ratios of risk factor coexistence.

    Tillman, Daniel

    The purpose of this three-paper manuscript dissertation was to study digital fabrication as an instructional technology for supporting elementary and middle school science and mathematics education. Article one analyzed the effects of digital fabrication activities that were designed to contextualize mathematics education at a summer mathematics enrichment program for upper elementary and middle school students. The primary dependent variables studied were the participants' knowledge of mathematics and science content, attitudes towards STEM (science, technology, engineering, and mathematics) and STEM-related careers. Based upon the data collected, three results were presented as having justifiable supporting empirical evidence: (1) The digital fabrication activities, combined with the other mathematics activities at the enrichment program, resulted in non-significant overall gains in students' mathematics test scores and attitudes towards STEM. (2) The digital fabrication activities, combined with the other mathematics activities at the enrichment program, resulted in noteworthy gains on the "Probability & Statistics" questions. (3) Some students who did poorly on the scored paper test on mathematics and science content were nonetheless nominated by their teachers as demonstrating meritorious distinction during the digital fabrication activities (termed "Great Thinkers" by the 5th-grade teachers). Article two focused on how an instructional technology course featuring digital fabrication activities impacted (1) preservice elementary teachers' efficacy beliefs about teaching science, and (2) their attitudes and understanding of how to include instructional technology and digital fabrication activities into teaching science. The research design compared two sections of a teaching with technology course featuring digital fabrication activities to another section of the same course that utilized a media cycle framework (Bull & Bell, 2005) that did not feature digital

    The use of kinematics is recommended to quantitatively evaluate upper limb movements. The aims of this study were to determine the age effects on upper limb kinematics and establish norms in healthy children. Ninety-three healthy children, aged 3-12 years, participated in this study. Twenty-eight kinematic indices were computed from four tasks. Each task was performed with the REAplan, a distal effector robotic device that allows upper limb displacements in the horizontal plane. Twenty-four of the 28 indices showed an improvement during childhood. Indeed, older children showed better upper limb movements. This study was the first to use a robotic device to show the age effects on upper limb kinematics and establish norms in healthy children.

    Acne vulgaris is the most common dermatological condition encountered in adolescents. It was to determine the prevalence of acne vulgaris and its impact of the quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. This was a cross-sectional study conducted in randomly selected governmental and technical secondary schools in Sohag Province, Upper Egypt. Approval was taken from the scientific research committee of Sohag Faculty of Medicine and also from Ministry of Education. Every student with acne was subjected to full medical history and local examination of head and neck to assess the severity of acne vulgaris. Assessment of the impact of acne vulgaris on their quality of life was carried out using self-reported validated specific questionnaire, the Cardiff Acne Disability Index (CADI). This study included 994 teenage secondary school students. The overall prevalence of acne vulgaris was 333 (33.5%). The mean age of the students with acne was 16.84±0.87. Acne vulgaris was more common among females than among males (200, 60% vs 133, 40%). The most common form of acne vulgaris was mild 178, 53%, followed by moderate form 135, 41%, and severe form 20, 6%. CADI score was significantly related to the disease grade and it was maximum among those with severe grade, followed by moderate and lastly mild disease grade. Acne vulgaris is a common skin disease and has a valuable impact on quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. © 2017 Wiley Periodicals, Inc.

  17. Social inclusion and career development--transition from upper secondary school to work or post-secondary education among hard of hearing students.

    The aim of this study was to investigate the decision process and to analyse the mechanisms involved in the transition from upper secondary education to post-secondary education or the labour market. Sixteen students with sensorioneural hearing loss were selected. Among these eight of the students continued to university and eight did not. Twenty-five per cent of the students were women and the average age was 28 years. The investigation was conducted about 5 years after graduation from the upper secondary school. Both quantitative and qualitative methods were used. The results showed that none of the students came from a family where any or both of the parents had a university or comparable education. The differences in choice between the two groups cannot be explained in terms of social inheritance. Our study indicates that given normal intellectual capacity the level of the hearing loss seems to have no predictive value regarding future educational performance and academic career. The conclusion is that it is of great importance that a hearing impaired pupil with normal intellectual capacity is encouraged and guided to choose an upper secondary educational programme which is orientated towards post-secondary education (instead of a narrow vocational programme). Additional to their hearing impairment and related educational problems, hard of hearing students have much more difficulty than normal hearing peers in coping with changes in intentions and goals regarding their educational career during their upper secondary education.

    The aim of this study was to explore how teachers and helpers experience that teacher-student relationship (TSR) is developed and promoted in upper secondary school.We also explored their experiences of qualities of TSR with students with mental health problems or at risk of dropping out. The study used a qualitative and participative approach; key stakeholders were included as co-researchers. Focus group interviews were held with 27 teachers and helpers. A thematic analysis was conducted. The participants' descriptions of important experiential dimensions of TSR were clustered around four themes: (1) to be recognized as a person with strengths and challenges in everyday life, (2) collaborative relationships between students and teachers, (3) flexible boundaries in the relationship between teachers and students and (4) organization of classes and procedures set the stage for TSR. Collaborative, emotional and contextual qualities were found important to the development of TSR in upper secondary school. Experiences of negative qualities of TSR can contribute to push students out of school. Teachers and helpers experience that TSR may have the potential to play a role in promoting mental health in students' everyday life.

    No data are available on caffeine consumption among Italian adolescents. We investigated caffeine intake from coffee, soft drinks and energy drinks in a sample of Italian adolescents and determined if they exceeded the recommended limits. The study comprised 1213 adolescents with a mean age of 15.1 years (range 12-19) from four schools in Foggia, southern Italy. Caffeine intake was assessed using an anonymous self-reported questionnaire during the 2013/2014 school year. We calculated the percentage of daily caffeine consumers, their mean intake of caffeine from beverages and the contribution of each beverage category to the total caffeine intake. Approximately 76% of the sample consumed caffeine every day, amounting to 125.5 ± 69.2 mg/day and 2.1 ± 1.2 mg/kg/day. When we applied the reference values from the Academy of Pediatrics, we found that 46% of the adolescents exceeded the recommended upper limits. Coffee was the most frequently consumed caffeinated drink and the main contributor to daily caffeine intake. More than three quarters (76%) of the Italian adolescents in our study drank coffee on a daily basis and nearly half (46%) exceeded the recommended upper limits. Strategies are needed to reduce caffeine consumption by adolescents. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    2017-10-01

    Full Text Available This paper examines the determinants of spending and the amount of time attending private supplementary tutoring, or commonly known as private tuition, in Malaysia. Based on 343 self-reported questionnaires with upper secondary students across three states in Malaysia and using multiple regression analysis, we identified ethnicity, father’s level of education and past academic performance as significant determinants of spending and amount of time attending private tuition. However, interestingly, we found that while geographical location and participation in internal tuition in schools were also determinants of spending, these two were not significant in determining the amount of time attending private supplementary tutoring. The identification of determinants of spending and amount of time, and in addition, the differences between these two illustrates the economic and educational dimensions of shadow education. More importantly, the insight also contributes to the formulation of possible interventions that can improve quality and reduce inequality in the mainstream education system.

    Full Text Available Indoor air quality (IAQ in nursery schools is an emerging public health challenge. Particular attention should be paid to younger children, because they are more vulnerable to air pollution than older children. Among air pollutants, fine particulate matter (PM2.5 is of the greatest interest mainly due to its strong association with acute and chronic effects on children’s health. In this paper, we present concentrations of PM2.5 and the composition of its trace elements at naturally ventilated nursery schools located in the area of Gliwice, Poland. The nursery schools were selected to characterize areas with different degrees of urbanization and traffic densities during the winter and spring seasons. The results indicate there is a problem with elevated concentrations of PM2.5 inside the examined classrooms. The children’s exposure to trace elements was different based on localization and season. PM2.5 concentration and its trace element composition have been studied using correlation coefficients between the different trace elements, the enrichment factor (EF and principal component analysis (PCA. PCA allowed the identification of the three components: anthropogenic and geogenic sources (37.2%, soil dust contaminated by sewage sludge dumping (18.6% and vehicular emissions (19.5%.

The aim is to assess the knowledge of secondary technical schools students on AIDS, identify related misconceptions, and measure the effect of a short health education program on their level of knowledge. Materials and Methods: This quasi-experimental study was done on 575 secondary technical schools students in Assiut City, recruited through a two-stage stratified cluster sampling. A self-administered anonymous questionnaire was used to collect data. A health education program was implemented, and its effect assessed through pre-post testing. Results: The age range of the students was 16 to 20 years, with more girls (57.0%. Only 30.8% had satisfactory knowledge about AIDS in the pretest. Statistically significant improvements in knowledge were revealed after program implementation (P<0.001. Students who were Muslim, of urban residence, and had mobile phones had significantly higher scores (P=0.037, 0.004, 0.038 respectively. The most common misconceptions were the definition of AIDS according to transmission, and phobias related to transmission, which decreased after the intervention. Multivariate analysis showed that the statistically significant independent predictors of the change in knowledge score after the intervention were age, religion and the health education program. Conclusion: Secondary technical schools students in Assiut city have a major deficiency in knowledge and many misconceptions regarding AIDS. The educational intervention had a positive impact on their knowledge, but a less marked effect on misconceptions. Knowledge was affected by age and religious belief. It is recommended that more health educational efforts tailored to needs and with approaches suitable to community cultures and values be introduced.

    Full Text Available Archaeology education benefits not only archaeologists, but also teachers and students. It fosters future stewards of our cultural heritage while making any classroom lesson more exciting and engaging for the students. In an effort to realize both of these goals, the author undertook an archaeology education programme in her local area of Upper Peninsula Michigan using a dual approach. She coordinated and implemented archaeology education activities in four local elementary schools during summer school, on a weekly basis, and developed and led an archaeology summer camp for children in conjunction with a local chapter of the 4-H Club. Teaching methods and activities varied between the two approaches; however, object handling was a key component of every lesson. Activities included learning about the instructor through examining objects she had brought from home, the dustbin game and skeleton game, a wastebasket excavation to learn context and stratigraphy, a mock excavation, a pot-mending activity, the creation of a museum exhibit, a “Maya Math” activity using the Maya numbering system, and a human evolution activity using replica hominid crania. Each approach presented its own challenges and rewards, but ultimately the author was able to inculcate over one hundred future stewards of our cultural heritage.

    Childhood obesity prevention is a pressing issue. Understanding the relationships among eating and physical activity behaviors and potential psychosocial determinants of behavior will help us design more effective interventions. This study aimed to examine such relationships in a large sample of urban elementary school children. Fifth grade students in 20 recruited New York City public schools completed a validated questionnaire on six "do more" (fruits and vegetables and physical activity) and "do less" (sweetened beverages, processed packaged snacks, fast food and sedentary behavior) energy balance related behaviors (EBRBs) and psychosocial determinants of behavior from social cognitive and self-determination theories. Correlations among behaviors and hierarchical linear model analyses of the relationship between psychosocial determinants and behaviors were conducted for those with complete data (n = 952). The "do more" and the "do less" behaviors were significantly correlated within categories (p food-related behaviors were correlated with physical activity but so were sports drinks, while the "do less" food-related behaviors tended to be correlated to sedentary behavior (p intention. Interventions can address the healthy and less healthy clusters of behaviors together, focusing on strategies to enhance their self-efficacy and habit strength for the "do more" behaviors and outcome expectations to motivate intention to choose fewer "do less" behaviors, along with enhancing self-efficacy and habit. Research can examine these determinants as potential mediators of change in intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

    With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers' cultural and economic assets, or capital, according to the work of Pierre Bourdieu's sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers' positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups' habituses are described and analyzed

    Childhood obesity has increased in recent decades in Korea. This study was designed to examine differences in the eating habits, physical activity (PA), nutrition knowledge, and self-efficacy of children by obesity status. Subjects were 5th-grade children from 70 elementary schools in 17 cities nationwide. Two-stage stratified cluster sampling was employed. Survey questionnaire included items related to general characteristics, eating habits, PA, nutrition knowledge and self-efficacy. Excluding incomplete responses, 3,531 data were analyzed using SPSS. Subjects were categorized into overweight·obesity (OW) and normal weight (NW) groups based on body mass index percentiles for age by sex. A total of 21.5% of subjects was overweight or obese. There were significant differences in gender, perceived stress, perception of body shape, body satisfaction, and interest in weight control between the OW and NW groups ( P eating habits, the OW group ate breakfast ( P eating habits, PA, and self-efficacy between OW and NW children. Obesity management programs for children need to focus on increasing self-efficacy, modifying eating habits, and increasing PA.

It was shown that the significance and accessibility of analyzed groups of values are, to a considerable extent, determined by a dominant motivation. Also, a tendency was found towards the contra-positioning of conscious and emotional attitudes with values — values which are highly attractive on the motivation-and-emotional level, but on the level of conscience, are underestimated compared with other ones. This also determines the further trend of development of a personality in the direction of acceptance of sociallyapproved general and educational values, and leads to the convergence of personality development of schoolchildren at that stage of their life. Also revealed were certain gender- related features of value orientations, which were relatinged to the more advanced development of girls when compared to boys of the same age.

    Argumentation skill is an essential skill needed in students, and one of the competencies in scientific literacy. Through arguing on socioscientific issues, students may gain deeper conceptual understanding. The purpose of this research is to examine the efficacy of a socioscientific issues-based instruction compared with an inquirybased instruction. This is to determine which one is better in promoting 10th grade students' argumentation ability and biology concepts of digestive system and cellular respiration. The forty 10th grade students included in this study were from two mathematics-science program classes in a medium-sized secondary school located in a suburb of Buriram province, Thailand. The research utilizes a quasi-experimental design; pre-test post-test control group design. We developed and implemented 4 lesson plans for both socioscientific issues-based instruction and inquiry-based instruction. Ten weeks were used to collect the data. A paper-based questionnaire and informal interviews were designed to test students' argumentation ability, and the two-tier multiple-choice test was designed to test their biology concepts. This research explore qualitatively and quantitatively students' argumentation abilities and biology concepts, using arithmetic mean, mean of percentage, standard deviation and t-test. Results show that there is no significant difference between the two group regarding mean scores of the argumentation ability. However, there is significant difference between the two groups regarding mean scores of the biology concepts. This suggests that socioscientific issues-based instruction could be used to improve students' biology concepts.

  2. Choices and changes: Eccles' Expectancy-Value model and upper-secondary school students' longitudinal reflections about their choice of a STEM education

    2016-03-01

    During the past 30 years, Eccles' comprehensive social-psychological Expectancy-Value Model of Motivated Behavioural Choices (EV-MBC model) has been proven suitable for studying educational choices related to Science, Technology, Engineering and/or Mathematics (STEM). The reflections of 15 students in their last year in upper-secondary school concerning their choice of tertiary education were examined using quantitative EV-MBC surveys and repeated qualitative interviews. This article presents the analyses of three cases in detail. The analytical focus was whether the factors indicated in the EV-MBC model could be used to detect significant changes in the students' educational choice processes. An important finding was that the quantitative EV-MBC surveys and the qualitative interviews gave quite different results concerning the students' considerations about the choice of tertiary education, and that significant changes in the students' reflections were not captured by the factors of the EV-MBC model. This questions the validity of the EV-MBC surveys. Moreover, the quantitative factors from the EV-MBC model did not sufficiently explain students' dynamical educational choice processes where students in parallel considered several different potential educational trajectories. We therefore call for further studies of the EV-MBC model's use in describing longitudinal choice processes and especially in investigating significant changes.

    The aim was to describe the occupational transition process to upper secondary school, further education and/or work, and to discover what support influences the process from the perspectives of young adults with Asperger syndrome or attention deficit/hyperactivity disorder. This qualitative study was performed in Sweden and comprised interviews with 15 young adults recruited from community based day centres. Support influencing the process included: occupational transition preparation in compulsory school, practical work experience in a safe environment, and support beyond the workplace. The overall understanding shows that the occupational transition process was a longitudinal one starting as early as in middle school, and continuing until the young adults obtained and were able to remain in employment or further education.

    Data on childhood blindness in Ghana are limited. The objectives of this study were to determine the major causes of childhood blindness and severe visual impairment (SVI) at Wa Methodist School for the Blind in Northern Ghana, and to compare our results to those published from other studies conducted in Ghana. In this retrospective study, data from an eye screening at Wa Methodist School in November 2014 were coded according to the World Health Organization/Prevention of Blindness standardized reporting methodology. Causes of blindness/SVI were categorized anatomically and etiologically, and were compared to previously published studies. Of 190 students screened, the major anatomical causes of blindness/SVI were corneal scar/phthisis bulbi (CS/PB) (n = 28, 15%) and optic atrophy (n = 23, 12%). The major etiological causes of blindness/SVI were unknown (n = 114, 60%). Eighty-three (44%) students became blind before age one year. Of four published blind school surveys conducted in Ghana, CS/PB was the most common anatomical cause of childhood blindness. Over time, the prevalence of CS/PB within blind schools decreased in the north and increased in the south. Measles-associated visual loss decreased from 52% in 1987 to 10% in 2014 at Wa Methodist School. In a blind school in northern Ghana, CS/PB was the major anatomical cause of childhood blindness/SVI. While CS/PB has been the most common anatomical cause of childhood blindness reported in Ghana, there may be regional changes in its prevalence over time. Being able to identify regional differences may guide future public health strategies to target specific causes.

    Orlander, Auli Arvola

    2016-12-01

    The aim of the study is to discuss and problematise notions of femininity and masculinity constructed in teaching situations among 16-year-old upper-secondary students studying science. The empirical examples originate from a teaching session with the theme of `sex and relationships'. The analysis is focused on metaphors inherent in a lesson that has its origins in the animal world. The findings show that the lesson `sex in the animal world' is full of anthropomorphism, metaphors that humanise animal behaviour. Teachers and students compare the animals' sexual behaviour with human behaviour, with the result that the animal world can be perceived as representative of natural sexual behaviour. The survey illustrates problems with how the examples are permeated by cultural values in the presentation of the animal world and how these examples form constructions of femininity and masculinity in the classroom.

    2014-05-01

    According to the requirements of the new core curriculum for Chemistry, students shall acquire knowledge through research and use the acquired chemical knowledge in their everyday life. However, in the recommended conditions and mode of implementation of the curriculum it is confirmed, that students' autonomous observation constitutes a basis for experiencing, inferences, analysis, and generalisations of phenomena [1]. It is obvious that teachers should create proper didactic situations, during which school students have a possibility to develop attitudes, skills and competences. More about competences we can find in the recommendations of the European Parliament and of the Council of 18 December 2006 on key competences for lifelong learning [2]. The detailed content of the core curriculum for the subject of chemistry at the fourth stage of education (basic level), we read: "4. Chemistry of soil. Student: 1) explains what the sorption properties of the soil are; plans and performs .... study of the sorption properties of the soil. " In the school year 2012/2013 chemistry teachers decided to offer students of a first-class to be involved in the project "Soil in the chemist's eye." It was considered that the method of the project is known from lower secondary school level and the teacher will have an opportunity to recognize students, who in the future, will choose the class with advanced chemistry program and determine the level of their skills, in particular the research skills. What we can offer to students does not necessarily take place in a well-equipped chemical laboratory. On the contrary, this process should be based on the well-known school subjects items, articles, objects and phenomena, which students meet in everyday life. The well-chosen methodologies and ways of showing the world will be, more understandable and skills will become a permanent part of the students, knowledge. Project characterization: a) The proposed project is problem-oriented, in

    Learning activities and course design in the new context of e-learning, such as in web-based courses involves a change both for teachers and students. The paper discusses factors important for e-learning to be successful. The development of an online course in medical physics and technology for high school teachers of physics, details of the course, and experience gained in connection with it are described. The course syllabus includes basics of radiation physics, imaging techniques using ionizing or non-ionizing radiation, and external and internal radiation therapy. The course has a highly didactic approach. The final task is for participants to design a course of their own centered on some topic of medical physics on the basis of the knowledge they have acquired. The aim of the course is to help the teachers integrate medical physics into their own teaching. This is seen as enhancing the interest of high school students in later studying physics, medical physics or some other branch of science at the university level, and as increasing the knowledge that they and people generally have of science. It is suggested that the basic approach taken can also have applicability to the training of medical, nursing or engineering students, and be used for continuing professional development in various areas.

    Full Text Available Background. Scientific and technical progress, intensification of educational process and information overload have a negative effect on unformed central nervous system of primary schoolchildren, causing stress, which affects the increase in the incidence of recurrent upper respiratory tract infections (URTI and the functional state of the myocardium. In view of this, we analyzed a functional state of myocardium in children with recurrent URTI. The critical duration of the work of primary school child with electronic means of communication, which affects the quality of nighttime sleep and the nature of awakening in the morning, was established. We have studied the relationship of the above mentioned with the incidence of URTI, the level of school anxiety and functional reserve of the myocardium. The purpose of the study was to evaluate the functional reserve of the myocardium in children of primary school age, depending on the incidence of URTI and the level of psycho-emotional activity. Materials and me­thods. 239 children aged 6 to 9 years were examined. The analysis of the functional reserve of the myocardium was carried out in pupils with different incidence of the URTI, depending on the age. The influence of electronic communications on the quality of nighttime sleep and morning awakening was stu­died, and the level of school anxiety was evaluated. During the study, children were divided into two groups. Group 1 — children with recurrent acute respiratory diseases (n = 143. Group 2 — children who occasionally have URTI (n = 96. Results. Out of 239 children with recurrent acute respiratory infections, we have identified 173 children with reduced functional reserve of the myocardium (72.4 %. Among children with recurrent URTI, the incidence of reduced functional reserve of the myocardium was 76.2 %, and in occasionally ill children — 66.7 %. Children with recurrent URTI use electronic means of communication more often than

    Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

    1984-01-01

    Historically, assessment of acute right upper quadrant abdominal pain has been a considerable clinical challenge. While clinical findings and laboratory data frequently narrow the differential diagnosis, symptom overlap generally precludes definitive diagnosis among the various diseases causing acute right upper quadrant pain. Fortunately, the advent of newer diagnostic imaging modalities has greatly improved the rapidity and reliability of diagnosis in these patients. An additional challenge to the physician, with increased awareness of the importance of cost effectiveness in medicine, is to select appropriate diagnostic schema that rapidly establish accurate diagnoses in the most economical fashion possible. The dual goals of this discussion are to assess not only the accuracy of techniques used to evaluate patients with acute right upper quadrant pain, but also to seek out cost-effective, coordinated imaging techniques to achieve this goal

    BACKGROUND: Computed tomography urography (CTU) is used widely in the work-up of patients with symptoms of urinary tract lesions. Preoperative knowledge of whether a tumor is invasive or non-invasive is important for the choice of surgery. So far there are no studies about the distinction...... of invasive and non-invasive tumors in ureter and renal pelvis based on the enhancement measured with Hounsfield Units. PURPOSE: To examine the value of CTU using split-bolus technique to distinguish non-invasive from invasive urothelial carcinomas in the upper urinary tract. MATERIAL AND METHODS: Patients...... obtained at CTU could distinguish between invasive and non-invasive lesions. No patients had a CTU within the last year before the examination that resulted in surgery. CONCLUSION: A split-bolus CTU cannot distinguish between invasive and non-invasive urothelial tumors in the upper urinary tract...

    Full Text Available Introduction : There is increasing interest in sedation for upper gastrointestinal endoscopy (UGE. Prospective randomized studies comparing sedation properties and complications of propofol and midazolam/meperidine in upper gastrointestinal endoscopy (UGE are few. Aim: To compare propofol and midazolam/meperidine sedation for UGE in terms of cardiopulmonary side effects, patient and endoscopist satisfaction and procedure-related times. Material and methods: This was a prospective, randomized, double-blind study of propofol versus midazolam and meperidine in 100 patients scheduled for diagnostic upper gastrointestinal endoscopy. The patients were divided into propofol and midazolam/meperidine groups. Randomization was generated by a computer. Cardiopulmonary side effects (hypotension, bradycardia, hypoxemia, procedure-related times (endoscopy time, awake time, time to hospital discharge, and patient and endoscopist satisfaction were compared between groups. Results: There was no significant difference between the groups with respect to the cost, endoscopy time, or demographic and clinical characteristics of the patients. Awake time and time to hospital discharge were significantly shorter in the propofol group (6.58 ±4.72 vs. 9.32 ±4.26 min, p = 0.030 and 27.60 ±7.88 vs. 32.00 ±10.54 min, p = 0.019. Hypotension incidence was significantly higher in the propofol group (12% vs. 0%, p = 0.027. The patient and endoscopist satisfaction was better with propofol. Conclusions : Propofol may be preferred to midazolam/meperidine sedation, with a shorter awake and hospital discharge time and better patient and endoscopist satisfaction. However, hypotension risk should be considered with propofol, and careful evaluation is needed, particularly in cardiopulmonary disorders.

    2013-01-01

    Golf is a global sport enjoyed by an estimated 60 million people around the world. Despite the common misconception that the risk of injury during the play of golf is minimal, golfers are subject to a myriad of potential pathologies. While the majority of injuries in golf are attributable to overuse, acute traumatic injuries can also occur. As the body's direct link to the golf club, the upper extremities are especially prone to injury. A thorough appreciation of the risk factors and patterns of injury will afford accurate diagnosis, treatment, and prevention of further injury.

    Hueih-Lirng Laih

    1998-09-01

    Full Text Available This paper explores the policy issues circling around the structural "transition" in upper secondary education implicit in the twenty-year increase in secondary and third-level school enrollment rates in Taiwan. This expansion has taken place within a secondary school system which is rigidly divided into both general, i.e., academic, and vocational tracks and into public and private sectors: the majority of students are enrolled in the private vocational sector which is only loosely articulated with the university sector. These features of the school system are analysed against the background of social and economic developments in Taiwan as well as public opinion. The analysis suggests that the present structures of school must be "reformed" in ways that will result in a more unified secondary system with both greater public funding and better articulation of all school types with the third level. The policy options that circle around the possibility of such reforms in the areas of curriculum, examination structures and second level-third level articulation are discussed and a policy framework for the reform of the Taiwan secondary education sector is outlined.

  11. 日本高級中等教育的「多樣化政策」分析:特色學校的教改理念與實施 Policies for the Diversification of Upper Secondary Education in Japan: Educational Reform Concepts and Their Implementation in Featured High Schools

    Directory of Open Access Journals (Sweden)

    劉語霏Yu-Fei Liu

    2014-03-01

    public has focused on school enrollment while overlooking the importance of school administration. In the postwar period, Japan implemented diversification policies for upper secondary education twice: in the 1960s and the 1990s. In the first phase, general education and vocational education were separated. In the second phase, featured high schools were promoted. Following the emergence of the comprehensive course in the 1990s, the government of Japan aggressively promoted special designations among high schools regardless of whether they were public, private, general, or specialized, including the Super Science High School, Super English Language High School, Becoming a Specialist, and Japanese Dual System designations. These designations were intended to develop schools’ characteristics, innovation, localization, and diversification, as well as to help schools implement featured curricula to become featured schools. The implementation of the featured high schools policy released teachers and students from existing curricula, leading them to develop creative teaching materials; it also provided junior high school students with multiple choices for secondary school. Moreover, it facilitated cooperation between local enterprises and high schools, and balanced development between urban and rural areas. This study suggests that for the 12-Year Basic Education policy, building featured high schools is not the same as eliminating elite high schools. Furthermore, it should not be confined to academic features. Although the enrollment strategy specified in the 12-Year Basic Education policy must be modified, the reform direction of the 12-Year Basic Education policy is in line with that implemented in Japan, and deserves recognition. Therefore, this study analyzed the development of policies for the diversification of upper secondary education in Japan through a literature review and a field survey. This study examined education reform concepts and their implementation in

  12. Oriental upper blepharoplasty.

    Science.gov (United States)

    Weng, Chau-Jin

    2009-02-01

    Aesthetic surgery of the upper eyelids is a very common procedure performed in cosmetic practices around the world. The word blepharoplasty, however, has a different meaning in Asia than it does elsewhere. Orientals have different periorbital anatomic characteristics, their motivations for seeking eyelid treatment are different, and operative techniques have been adapted consequently. There are also many eyelid shapes among Orientals, mostly with regard to the presence and location of the supratarsal fold and/or presence of an epicanthal fold. The surgeon must therefore master a range of surgical procedures to treat these variations adequately. It is critical to know the indications for each blepharoplasty technique as well as their complications to select the right surgery and avoid unfavorable results. Epicanthoplasty performed on the right patient can greatly improve aesthetic results while retaining ethnic characteristics. This article will discuss Oriental eyelid characteristics, preoperative patient assessment, commonly used corrective techniques for the "double-eyelid" creation, and complications and how to avoid them.

    Montserrat, J M; Badia, J R

    1999-03-01

    This article reviews the clinical picture, diagnosis and management of the upper airway resistance syndrome (UARS). Presently, there is not enough data on key points like the frequency of UARS and the morbidity associated with this condition. Furthermore, the existence of LIARS as an independent sleep disorder and its relation with snoring and obstructive events is in debate. The diagnosis of UARS is still a controversial issue. The technical limitations of the classic approach to monitor airflow with thermistors and inductance plethysmography, as well as the lack of a precise definition of hypopnea, may have led to a misinterpretation of UARS as an independent diagnosis from the sleep apnea/hypopnea syndrome. The diagnosis of this syndrome can be missed using a conventional polysomnographic setting unless appropriate techniques are applied. The use of an esophageal balloon to monitor inspiratory effort is currently the gold standard. However, other sensitive methods such as the use of a pneumotachograph and, more recently, nasal cannula/pressure transducer systems or on-line monitoring of respiratory impedance with the forced oscillation technique may provide other interesting possibilities. Recognition and characterization of this subgroup of patients within sleep breathing disorders is important because they are symptomatic and may benefit from treatment. Management options to treat UARS comprise all those currently available for sleep apnea/hypopnea syndrome (SAHS). However, the subset of patients classically identified as LIARS that exhibit skeletal craneo-facial abnormalities might possibly obtain further benefit from maxillofacial surgery.

    1998-01-01

    During the past 25 years, industry and government made large financial investments that resulted in better water quality across the Nation; however, many water-quality concerns remain. Following a 1986 pilot project, the U.S. Geological Survey began implementation of the National Water-Quality Assessment (NAWQA) Program in 1991. This program differs from other national water-quality assessment studies in that the NAWQA integrates monitoring of surface- and ground-water quality with the study of aquatic ecosystems. The goals of the NAWQA Program are to (1) describe current water-quality conditions for a large part of the Nation's freshwater streams and aquifers (water-bearing sediments and rocks), (2) describe how water quality is changing over time, and (3) improve our understanding of the primary natural and human factors affecting water quality.The Upper Illinois River Basin National Water- Quality Assessment (NAWQA) study will increase the scientific understanding of surface- and ground-water quality and the factors that affect water quality in the basin. The study also will provide information needed by water-resource managers to implement effective water-quality management actions and evaluate long-term changes in water quality.

    Sarcoidosis is a chronic granulomatous disease of unknown aetiology. It can affect any part of the organism, although the lung is the most frequently affected organ. Upper airway involvement is rare, particularly if isolated. Sarcoidosis is a diagnosis of exclusion, established by histological evidence of non-caseating granulomas and the absence of other granulomatous diseases. The authors report a case of a man with sarcoidosis manifesting as a chronic inflammatory stenotic condition of the upper respiratory tract and trachea. PMID:27090537

    Tumors located in the upper/upper inner quadrant of the breast warrant more attention. A small lesion relative to the size of breast in this location may be resolved by performing a level I oncoplastic technique. However, a wide excision may significantly reduce the overall quality of the breast shape by distorting the visible breast line. From June 2012 to April 2015, 36 patients with breast cancer located in the upper/upper inner quadrant underwent breast-conservation surgery with matrix rotation mammoplasty. According to the size and location of the tumor relative to the nipple-areola complex, 11 patients underwent matrix rotation with periareolar de-epithelialization (donut group) and the other 25 underwent matrix rotation only (non-donut group). The cosmetic results were self-assessed by questionnaires. The average weights of the excised breast lumps in the donut and non-donut groups were 104.1 and 84.5 g, respectively. During the 3-year follow-up period, local recurrence was observed in one case and was managed with nipple-sparing mastectomy followed by breast reconstruction with prosthetic implants. In total, 31 patients (88.6%) ranked their postoperative result as either acceptable or satisfactory. The treated breasts were also self-evaluated by 27 patients (77.1%) to be nearly identical to or just slightly different from the untreated side. Matrix rotation is an easy breast-preserving technique for treating breast cancer located in the upper/upper inner quadrant of the breast that requires a relatively wide excision. With this technique, a larger breast tumor could be removed without compromising the breast appearance.

    This thesis provides a description of the technical and medical aspects of arteriography of the upper extremity and an extensive analysis of the angiographic anatomy and pathology of 750 selective studies performed in more than 500 patients. A short historical review is provided of angiography as a whole and of arteriography of the hand in particular. The method of percutaneous transfemoral catheterization of the arteries of the upper extremity and particularly the arteries of the hand is considered, discussing the problems the angiographer encounters frequently, describing the angiographic complications which may occur and emphasizing the measures to keep them to a minimum. The use of vasodilators in hand angiography is discussed. A short description of the embryological patterns persisting in the arteries of the arm is included in order to understand the congenital variations of the arteries of the upper extremity. The angiographic patterns and clinical aspects of the most common pathological processes involving the arteries of the upper extremities are presented. Special attention is paid to the correlation between angiography and pathology. (Auth.)

    When in 1980 the Upper Danube Nature Park was founded as one of 65 nature sanctuaries in Germany there was great diversity of opinions concerning its intended character. The protected region consisting of a geologically outstanding landscape within central Europe is covering the first 80 km the upper Danube where the young river shortly after it's source in the Black Forest is breaking through the narrow canyons of the Jurassic rock plateau of the so-called Suebian Alps and also locates the subterranean passage where the stream is submerging from the surface for nearly ten miles. Since the purpose of nature preservation according to German las is closely combined with the rather contradicting aim of offering an attractive recreation area thus facing the immense impacts of modern mass tourism there are numerous problems which in the course of years have resulted in an intricate patterns of subtle management methods coping with the growing awareness of the ecological balance.

    2011-01-01

    Stroke survivors with hemiparesis and spinal cord injury (SCI) survivors with tetraplegia find it difficult or impossible to perform many activities of daily life. There is growing evidence that intensive exercise therapy, especially when supplemented with functional electrical stimulation (FES), can improve upper extremity function, but delivering the treatment can be costly, particularly after recipients leave rehabilitation facilities. Recently, there has been a growing level of interest among researchers and healthcare policymakers to deliver upper extremity treatments to people in their homes using in-home teletherapy (IHT). The few studies that have been carried out so far have encountered a variety of logistical and technical problems, not least the difficulty of conducting properly controlled and blinded protocols that satisfy the requirements of high-level evidence-based research. In most cases, the equipment and communications technology were not designed for individuals with upper extremity disability. It is clear that exercise therapy combined with interventions such as FES, supervised over the Internet, will soon be adopted worldwide in one form or another. Therefore it is timely that researchers, clinicians, and healthcare planners interested in assessing IHT be aware of the pros and cons of the new technology and the factors involved in designing appropriate studies of it. It is crucial to understand the technical barriers, the role of telesupervisors, the motor improvements that participants can reasonably expect and the process of optimizing IHT-exercise therapy protocols to maximize the benefits of the emerging technology.

    2014-11-01

    Full Text Available Since 2009, most Norwegian students in upper secondary have had access to their own personal computer at school. Hence, with the increased access to technology, the importance of online connectedness has increased for adolescents’ social interaction and communication. It is, therefore, important to identify and understand the concept of Internet safety among upper secondary school students. A total of 4216 students from 238 classrooms in 23 upper secondary schools completed an Internet safety assessment. The aim of the study was to operationalize and measure Internet safety in a school context, and to further examine the factors predicting students’ Internet safety awareness and responsibility. Our analysis revealed substantial variation in Internet safety awareness between schools, classrooms and students. Overall, the findings indicate that students’ social backgrounds are determining for their development and understanding of Internet safety awareness.

    2004-01-01

    The detailed characterization of the Mars upper atmosphere is important for future Mars aerobraking activities. Solar cycle, seasonal, and dust trends (climate) as well as planetary wave activity (weather) are crucial to quantify in order to improve our ability to reasonably depict the state of the Mars upper atmosphere over time. To date, our best information is found in the Mars Global Surveyor (MGS) Accelerometer (ACC) database collected during Phase 1 (Ls = 184 - 300; F10.7 = 70 - 90) and Phase 2 (Ls = 30 - 90; F10.7 = 90 - 150) of aerobraking. This database (100 - 170 km) consists of thermospheric densities, temperatures, and scale heights, providing our best constraints for exercising the coupled Mars General Circulation Model (MGCM) and the Mars Thermospheric General Circulation Model (MTGCM). The Planetary Data System (PDS) contains level 0 and 2 MGS Accelerometer data, corresponding to atmospheric densities along the orbit track. Level 3 products (densities, temperatures, and scale heights at constant altitudes) are also available in the PDS. These datasets provide the primary model constraints for the new MGCM-MTGCM simulations summarized in this report. Our strategy for improving the characterization of the Mars upper atmospheres using these models has been three-fold : (a) to conduct data-model comparisons using the latest MGS data covering limited climatic and weather conditions at Mars, (b) to upgrade the 15-micron cooling and near-IR heating rates in the MGCM and MTGCM codes for ad- dressing climatic variations (solar cycle and seasonal) important in linking the lower and upper atmospheres (including migrating tides), and (c) to exercise the detailed coupled MGCM and MTGCM codes to capture and diagnose the planetary wave (migrating plus non-migrating tidal) features throughout the Mars year. Products from this new suite of MGCM-MTGCM coupled simulations are being used to improve our predictions of the structure of the Mars upper atmosphere for the

Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H1-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines. Intranasal corticosteroids have broad anti-inflammatory activities, are the most potent long-term pharmacologic treatment of congestion associated with allergic rhinitis, and show some congestion relief in rhinosinusitis and nasal polyposis. Immunotherapy and surgery may be used in some cases refractory to pharmacotherapy. Steps in congestion management include (1 diagnosis of the cause(s, (2 patient education and monitoring, (3 avoidance of environmental triggers where possible, (4 pharmacotherapy, and (5 immunotherapy

    The Composites for Exploration Upper Stage (CEUS) was a 3-year, level III project within the Technology Demonstration Missions program of the NASA Space Technology Mission Directorate. Studies have shown that composites provide important programmatic enhancements, including reduced weight to increase capability and accelerated expansion of exploration and science mission objectives. The CEUS project was focused on technologies that best advanced innovation, infusion, and broad applications for the inclusion of composites on future large human-rated launch vehicles and spacecraft. The benefits included near- and far-term opportunities for infusion (NASA, industry/commercial, Department of Defense), demonstrated critical technologies and technically implementable evolvable innovations, and sustained Agency experience. The initial scope of the project was to advance technologies for large composite structures applicable to the Space Launch System (SLS) Exploration Upper Stage (EUS) by focusing on the affordability and technical performance of the EUS forward and aft skirts. The project was tasked to develop and demonstrate critical composite technologies with a focus on full-scale materials, design, manufacturing, and test using NASA in-house capabilities. This would have demonstrated a major advancement in confidence and matured the large-scale composite technology to a Technology Readiness Level 6. This project would, therefore, have bridged the gap for providing composite application to SLS upgrades, enabling future exploration missions.

    Berneburg, Mirjam; Meller, Christian

    2016-01-01

    This case report describes our therapeutic approach taken in a girl with eruption disturbance of the upper anterior teeth. Two supernumerary teeth were involved, which required a combination of orthodontic and surgical treatment. The initial situation in the upper anterior segment was characterized by two supernumerary mesial incisors, ectopic eruption of the distally located lateral incisors, and crowded tooth buds in the canine areas. Key decisions had to be made as to whether any teeth needed to be extracted and, if so, regarding the timing and sites of extraction. Removing teeth too early would have preempted a complete assessment of tooth quality, whereas late extraction would have carried a risk of eruption disturbance. Once the distal lateral incisors had erupted, the supernumerary mesial incisors were extracted and the central incisors (initially located in between) mesialized with a bracket appliance. Following space closure and mesialization of the lateral incisors, a functional appliance was used. Tooth 13 was erupting, while tooth 23 was displaced and subsequently aligned as part of the final bracket treatment. To successfully treat eruption disturbances, a careful diagnostic workup is essential, including informative radiographs, personalized treatment planning, and correct decision-making as to whether teeth need to be extracted and regarding the timing and sites of extraction. Finally, the eruption of the canines should be monitored.

    Full Text Available The human face is composed of small functional and cosmetic units, of which the eyes and periocular region constitute the main point of focus in routine face-to-face interactions. This dynamic region plays a pivotal role in the expression of mood, emotion, and character, thus making it the most relevant component of the facial esthetic and functional unit. Any change in the periocular unit leads to facial imbalance and functional disharmony, leading both the young and the elderly to seek consultation, thus making blepharoplasty the surgical procedure of choice for both cosmetic and functional amelioration. The applied anatomy, indications of upper eyelid blepharoplasty, preoperative workup, surgical procedure, postoperative care, and complications would be discussed in detail in this review article.

    Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients’ everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients’ prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed...

    This paper considers the concept of fuzzy upper bounds and provides some relevant applications. Considering a fuzzy DEA model, the existence of a fuzzy upper bound for the objective function of the model is shown and an effective approach to solve that model is introduced. Some dual interpretations are provided, which are useful for practical purposes. Applications of the concept of fuzzy upper bounds in two physical problems are pointed out.

  12. Russia's social upper class: from ostentation to culturedness.

    Science.gov (United States)

    Schimpfossl, Elisabeth

    2014-03-01

    This article discusses examples of strategies employed by representatives of Russia's new social upper class to acquire social distinction. By the late 2000s many of the upper-class Russians included in this study distanced themselves from the conspicuous ostentation ascribed to the brutish 1990s. Instead, they strove to gain legitimacy for their social position by no longer aggressively displaying their wealth, but instead elaborating more refined and individualized tastes and manners and reviving a more cultured image and self-image. These changes found their expression in various modes of social distinction ranging from external signs, such as fashion and cars, to ostentation vicariously exercised through the people these upper-class Russians surrounded themselves with. The article will trace these interviewees' strategies for distinction in the late 2000s by discussing tastes in lifestyle and consumption as well as adornment through sartorial signs and through vicarious ostentation, as exemplified by their choice of female company. Changing attitudes towards vehicles and modes of transport, with special regards to the Moscow Metro, will serve as a further illustration of modes of distinction. Crucial for this discussion is the role of the Russian/Soviet intelligentsia, both for vicarious status assertion and elite distinction anchored in the interviewees' social backgrounds. © London School of Economics and Political Science 2014.

    1984-01-01

    A model for the emergency core cooling injection into the upper plenum of a boiling water reactor has been formulated and implemented into the TRACB02 computer program. The model consists of a spray model and a submerged jet model. The submerged jet model is used when the spray nozzles are covered by a two-phase mixture, and the spray model is used when the nozzles are uncovered. The upper plenum model has been assessed by comparison to an upper plenum mixing test in the Steam Sector Test Facility. It is found that the model accurately predicts the phenomena in the upper plenum of a boiling water reactor

  14. Upper gastrointestinal bleeding - state of the art.

    Science.gov (United States)

    Szura, Mirosław; Pasternak, Artur

    2014-01-01

    Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

  15. Smartphone supported upper limb prosthesis

    2015-09-01

    Full Text Available State of the art upper limb prostheses offer up to six active DoFs (degrees of freedom and are controlled using different grip patterns. This low number of DoFs combined with a machine-human-interface which does not provide control over all DoFs separately result in a lack of usability for the patient. The aim of this novel upper limb prosthesis is both offering simplified control possibilities for changing grip patterns depending on the patients’ priorities and the improvement of grasp capability. Design development followed the design process requirements given by the European Medical Device Directive 93/42 ECC and was structured into the topics mechanics, software and drive technology. First user needs were identified by literature research and by patient feedback. Consequently, concepts were evaluated against technical and usability requirements. A first evaluation prototype with one active DoF per finger was manufactured. In a second step a test setup with two active DoF per finger was designed. The prototype is connected to an Android based smartphone application. Two main grip patterns can be preselected in the software application and afterwards changed and used by the EMG signal. Three different control algorithms can be selected: “all-day”, “fine” and “tired muscle”. Further parameters can be adjusted to customize the prosthesis to the patients’ needs. First patient feedback certified the prosthesis an improved level of handling compared to the existing devices. Using the two DoF test setup, the possibilities of finger control with a neural network are evaluated at the moment. In a first user feedback test, the smartphone based software application increased the device usability, e.g. the change within preselected grip patterns and the “tired muscle” algorithm. Although the overall software application was positively rated, the handling of the prosthesis itself needs to be proven within a patient study to be

    Most of the understanding of the thermosphere resulted from the analysis of data accrued through the Atmosphere Explorer satellites, the Dynamics Explorer 2 satellite, and observations from rockets, balloons, and ground based instruments. However, new questions were posed by the data that have not yet been answered. The mesosphere and lower thermosphere have been less thoroughly studied because of the difficulty of accessibility on a global scale, and many rather fundamental characteristics of these regions are not well understood. A wide variety of measurement platforms can be used to implement various parts of a measurement strategy, but the major thrusts of the International Solar Terrestrial Physics Program would require Explorer-class missions. A remote sensing mission to explore the mesosphere and lower thermosphere and one and two Explorer-type spacecraft to enable a mission into the thermosphere itself would provide the essential components of a productive program of exploration of this important region of the upper atomsphere. Theoretical mission options are explored

    Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR.

    The aim of this study was to obtain information about the mechanisms and types of injuries in school in Austria. Children between 0 and 18 years of age presenting with injuries at the trauma outpatient in the Department of Pediatric Surgery in Graz and six participating hospitals in Austria were evaluated over a 2-year prospective survey. A total of 28,983 pediatric trauma cases were registered. Personal data, site of the accident, circumstances and mechanisms of accident and the related diagnosis were evaluated. At the Department of Pediatric Surgery in Graz 21,582 questionnaires were completed, out of which 2,148 children had school accidents (10%). The remaining 7,401 questionnaires from peripheral hospitals included 890 school accidents (12%). The male/female ratio was 3:2. In general, sport injuries were a predominant cause of severe trauma (42% severe injuries), compared with other activities in and outside of the school building (26% severe injuries). Injuries during ball-sports contributed to 44% of severe injuries. The upper extremity was most frequently injured (34%), followed by lower extremity (32%), head and neck area (26%) and injuries to thorax and abdomen (8%). Half of all school related injuries occur in children between 10 and 13 years of age. There are typical gender related mechanisms of accident: Boys get frequently injured during soccer, violence, and collisions in and outside of the school building and during craft work. Girls have the highest risk of injuries at ball sports other than soccer.

    Grimmer, K; Nyland, L; Milanese, S

    2006-07-01

    The epidemiological and clinical literature identifies strong associations between adult headache, cervical and thoracic spine dysfunction and spinal posture. This paper reports on the prevalence and incidence of headache, neck and upper back pain which occurred in the previous week, in urban Australians aged 13-17 years. Commencing in 1999, we followed a cohort of South Australian students through 5 years of secondary schooling. Of our commencing cohort of students, 132 (30%) provided data on bodily pain every year. For both girls and boys, there was a significantly decreasing prevalence of headache over the study period, while neck pain and upper back pain increased. There was a significantly increasing trend over time for boys with upper back pain. Twenty percent of girls and boys consistently reported headache, neck pain or upper back pain over 5 years. The progression of early adolescent headaches to mid-adolescent neck and upper back pain potentially reflects the adolescents' biomechanical responses to intrinsic and extrinsic imposts. This requires further investigation to understand the causes of adolescent headache, neck and upper thoracic pain.

    The morphology and mechanical properties of upper bainite formed isothermally at 400 deg. C for different holding times in a 1.83 wt.% silicon steel have been investigated by optical metallograph, X-ray diffraction and transmission electron microscopy (TEM). In the early stage of upper bainitic transformation, lathlike bainite whose individual lath ferrite is separated by the thin film type of retained austenite is obtained. As the isothermal holding times are increased, the blocky region consisting of retained austenite and martensite is also found. The stability of retained austenite in lathlike upper bainite is studied in relation to the isothermal treatment times, and the heat treatment conditions. The results show that an optimum combination of strength and ductility is attributed to the formation of bainitic ferrite (BF) and a large amount of thin film carbon-enriched retained austenite in the upper bainite

    The incidence of gastrointestinal disorders among patients with chronic kidney disease (CKD) is high, despite the lack of a good correlation between endoscopic findings and symptoms. Many services thus perform upper gastrointestinal (UGI) endoscopy on kidney transplant candidates. This study aims to describe the alterations seen on the upper endoscopies of 96 kidney-transplant candidates seen from 2014 to 2015. Ninety-six CKD patients underwent upper endoscopic examination as part of the preparation to receive kidney grafts. The data collected from the patients' medical records were charted on Microsoft Office Excel 2016 and presented descriptively. Mean values, medians, interquartile ranges and 95% confidence intervals of the clinic and epidemiological variables were calculated. Possible associations between endoscopic findings and infection by H. pylori were studied. Males accounted for 54.17% of the 96 patients included in the study. Median age and time on dialysis were 50 years and 50 months, respectively. The most frequent upper endoscopy finding was enanthematous pangastritis (57.30%), followed by erosive esophagitis (30.20%). Gastric intestinal metaplasia and peptic ulcer were found in 8.33% and 7.30% of the patients, respectively. H. pylori tests were positive in 49 patients, and H. pylori infection was correlated only with non-erosive esophagitis (P = 0.046). Abnormal upper endoscopy findings were detected in all studied patients. This study suggested that upper endoscopy is a valid procedure for kidney transplant candidates. However, prospective studies are needed to shed more light on this matter.

    The results of an escapement survey for tributaries to the Kinbasket Reservoir and the Upper Columbia River were provided. Two aerial surveys were conducted during October, 2005. The Kokanee were grouped in schools and summed in order to provide independent estimates. Otoliths of the fish were also extracted in order to determine their age. Results of the survey showed that an estimated 236,760 Kokanee fish were spawning within 11 index streams and rivers within the Kinbasket Reservoir drainage area. Mean fork length was estimated at 24.7 cm. While the Columbia River continues to be the most important Kokanee spawning location in the Kinbasket Reservoir drainage area, the 2005 Kokanee escapement index was the third lowest recorded since 1996. It was concluded that declining fish size and declining abundance may indicate reduced reservoir productivity. 5 refs., 1 tab., 4 figs

    A high percentage of all sports injuries occur during school sports. It was analysed whether there are differences in frequency, nature and distribution of school sport injuries at two different types of schools. School sport injuries of all secondary modern schools (n = 106) and in lower classes of grammar Schools (n = 17) in the federal state of Tyrol, Austria, from the ten school years 2001/02 to 2010/11 were analysed. All physical injuries occurring during school sports and resulting in the consultation of a medical doctor and therefore being reported to the general accident department (Allgemeine Unfallversicherungsanstalt [AUVA]) were assessed. During the evaluation period an average number of 32,935 (±1584) school children attended the two types of schools in Tyrol per year. The average incidence of school sports injuries in this ten-year period in both types of schools was 36.4/1,000 (mean) with a standard deviation of 4.4/1,000 per school child per year. The incidence increased from 30.3 in the school year 2001/02 to 40.4 in the school year 2010/11 (r = 0.91; b = 1.34; p school sport injuries at secondary modern schools (37.4 ± 4.9 per 1,000 school children per year) was higher than at the lower classes of grammar schools (32.9 ± 4.0 per 1,000 school children per year; relative risk 1.138; 95% CI = 1.09-1.19; p = 1.8 × 10-8). In addition, the sports injuries of the school year 2010/11 were analysed in detail and a comparison was made between the two types of schools. The distribution pattern of school sports injuries did not show any significant differences between both school types. At the secondary modern schools, as well as in the lower classes of grammar schools, injuries to the upper extremities prevailed (>50%). Ball sports were responsible for every second injury. Secondary modern school pupils had a significantly higher risk of suffering a school sports injury than pupils in the lower classes of grammar schools. The injury pattern did not show

  3. ON COMPUTING UPPER LIMITS TO SOURCE INTENSITIES

    2010-01-01

    A common problem in astrophysics is determining how bright a source could be and still not be detected in an observation. Despite the simplicity with which the problem can be stated, the solution involves complicated statistical issues that require careful analysis. In contrast to the more familiar confidence bound, this concept has never been formally analyzed, leading to a great variety of often ad hoc solutions. Here we formulate and describe the problem in a self-consistent manner. Detection significance is usually defined by the acceptable proportion of false positives (background fluctuations that are claimed as detections, or Type I error), and we invoke the complementary concept of false negatives (real sources that go undetected, or Type II error), based on the statistical power of a test, to compute an upper limit to the detectable source intensity. To determine the minimum intensity that a source must have for it to be detected, we first define a detection threshold and then compute the probabilities of detecting sources of various intensities at the given threshold. The intensity that corresponds to the specified Type II error probability defines that minimum intensity and is identified as the upper limit. Thus, an upper limit is a characteristic of the detection procedure rather than the strength of any particular source. It should not be confused with confidence intervals or other estimates of source intensity. This is particularly important given the large number of catalogs that are being generated from increasingly sensitive surveys. We discuss, with examples, the differences between these upper limits and confidence bounds. Both measures are useful quantities that should be reported in order to extract the most science from catalogs, though they answer different statistical questions: an upper bound describes an inference range on the source intensity, while an upper limit calibrates the detection process. We provide a recipe for computing upper

    Full Text Available The present study provides a detailed analysis of upper secondary education dropout patterns in Mexico, exploring its consequences and possible causes. To perform the analysis we combine different databases and statistical methods ranging from the use of surveys with information on specific individuals to data aggregated at the municipal and state level. The main value added is the simultaneous analysis of the influence of individual-family, community, and macroaggregate factors, on school dropout in the country.

  7. Interventional studies of the upper gastrointestinal tract

    Shapiro, B.; Gross, M.D.

    1985-01-01

    Nuclear Medicine studies of the upper gastrointestinal (GI) tract provide a means whereby physiologic and pathophysiologic features can be observed from a unique and noninvasive perspective. While nuclear medicine studies by their very nature lack the high spatial resolution of the radiographic approach, the data derived are readily quantitated and presented in numerical fashion to provide functional and dynamic information in which the influences of interventions may be observed. This chapter outlines the scope of such interventions in studies of the upper GI tract with emphasis on examinations for gastroesophageal reflux and gastric emptying. The interactions of nutrients, physical maneuvers of pharmacologic agents on nuclear medicine studies of the upper GI tract may be intentional to render a test more sensitive or to evaluate the effect of therapy, or may represent an unintentional side effect that must be taken into account if misinterpretation is to be avoided

    It was considered that the most important elements of the treatment used in the rehabilitation of the paretic upper limb are: exercise matching the anti-spasm pattern, maintaining appropriate position for exercise that provide an approximation of the shoulder joint and the use of cross-facilitation. The study indicates that the treatment of a post stroke upper limb should be based on the: physiotherapy, kinesiotherapy and specific positioning - all of them corresponding to a given stage of the disease. The work also presents the most frequently used methods, especially highlighting: the Prorioceptive Neuromuscular Facilitation (PNF, Bobath, Brunnstrom, CIMT and OIT. It was also shown that in order to enhance the effects of a post-stroke upper limb rehabilitation, it should be extended by modern methods such as Mirror Therapy, Virtual Reality or Robot-assisted Therapy.

  9. Upper entropy axioms and lower entropy axioms

    International Nuclear Information System (INIS)

    Guo, Jin-Li; Suo, Qi

    2015-01-01

    The paper suggests the concepts of an upper entropy and a lower entropy. We propose a new axiomatic definition, namely, upper entropy axioms, inspired by axioms of metric spaces, and also formulate lower entropy axioms. We also develop weak upper entropy axioms and weak lower entropy axioms. Their conditions are weaker than those of Shannon–Khinchin axioms and Tsallis axioms, while these conditions are stronger than those of the axiomatics based on the first three Shannon–Khinchin axioms. The subadditivity and strong subadditivity of entropy are obtained in the new axiomatics. Tsallis statistics is a special case of satisfying our axioms. Moreover, different forms of information measures, such as Shannon entropy, Daroczy entropy, Tsallis entropy and other entropies, can be unified under the same axiomatics

    Two cross-sections of the western Mediterranean Neogene-to-present backarc basin are presented, in which geological and geophysical data of the Transmed project are tied to a new shear-wave tomography. Major results are i) the presence of a well stratified upper mantle beneath the older African continent, with a marked low-velocity layer between 130-200 km of depth; ii) the dilution of this layer within the younger western Mediterranean backarc basin to the north, and iii) the easterly raising of a shallower low-velocity layer from about 140 km to about 30 km in the Tyrrhenian active part of the backarc basin. These findings suggest upper mantle circulation in the western Mediterranean backarc basin, mostly easterly-directed and affecting the boundary between upper asthenosphere (LVZ) and lower asthenosphere, which undulates between about 180 km and 280 km.

    An upper dominating set in a graph is a minimal (with respect to set inclusion) dominating set of maximum cardinality.The problem of finding an upper dominating set is generally NP-hard, but can be solved in polynomial time in some restricted graph classes, such as P4-free graphs or 2K2-free graphs.For classes defined by finitely many forbidden induced subgraphs, the boundary separating difficult instances of the problem from polynomially solvable ones consists of the so called boundary classes.However, none of such classes has been identified so far for the upper dominating set problem.In the present paper, we discover the first boundary class for this problem.

    Hypnosis is a therapeutic technique that primarily involves attentive receptive concentration. Even though a small number of health professionals are trained in hypnosis and lingering myths and misconceptions associated with this method have hampered its widespread use to treat medical conditions, hypnotherapy has gained relevance as an effective treatment for irritable bowel syndrome not responsive to standard care. More recently, a few studies have addressed the potential influence of hypnosis on upper digestive function and disease. This paper reviews the efficacy of hypnosis in the modulation of upper digestive motor and secretory function. The present evidence of the effectiveness of hypnotherapy as a treatment for functional and organic diseases of the upper bowel is also summarized, coupled with a discussion of potential mechanisms of its therapeutic action.

    Webs of the upper oesophagus are sail-like mucosal folds of unknown aetiology. Small, transverse webs on the anterior wall of the oesophagus are not uncommon incidental findings which are easily overlooked on routine examination. Extensive, circular membranes in the upper oesophagus, on the other hand, are rare; these may lead to severe difficulty with swallowing and may be associated with regurgitation. One example of a transverse, and three cases of circular webs are described, which caused stenosis and dysphagia and which, in some cases, were multiple. The aetiology is discussed. (orig.) [de

    Evaluations of upper gastrointestinal toxicity from ketamine abuse are uncommon. This study investigated the clinical pattern of upper gastrointestinal symptoms in patients inhaling ketamine. In a cross-sectional study of 611 consecutive patients who were seeking treatment for ketamine uropathy in a tertiary hospital setting between August 2008 and June 2016, their clinical pattern of upper gastrointestinal symptoms was evaluated and compared with a control population of 804 non-users. A total of 168 (27.5%) patients abusing ketamine (mean age 26.3 years, 58.9% female) reported the presence of upper gastrointestinal symptoms. These symptoms were significantly more prevalent in patients inhaling ketamine than in those who were not (27.5% vs 5.2%, P ketamine abuse before symptom presentation was 5.0 ± 3.1 years. The presenting symptoms included epigastric pain (n = 155, 25.4%), recurrent vomiting (n = 48, 7.9%), anemia (n = 36, 5.9%) and gastrointestinal bleeding (n = 20, 3.3%). Uropathy symptoms were preceded by upper gastrointestinal symptoms for 4.4 ± 3.0 years in 141 (83.9%) patients. Logistic regression showed that elder age (odds ratio [OR] 1.06, P = 0.04), active abuser status (OR 1.60, P = 0.04) and longer duration of ketamine abuse (OR 1.00, P = 0.04) were independent factors associated with upper gastrointestinal toxicity. Although epigastric symptoms are unusual in the young population, upper gastrointestinal toxicity was highly prevalent in those inhaling ketamine. Enquiries about ketamine abuse are recommended when assessing young patients with epigastric symptoms. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

  2. Upper arm circumference measurement for detecting overweight and obesity in children aged 6-7 years

    2017-02-01

    Full Text Available Background Obesity is a worldwide problem and is associated with increased risk of metabolic syndrome. Nutritional status in children has traditionally been determined by body mass index (BMI scores, but with limitations. Upper arm circumference measurement may be a better predictor of energy, protein, and fat storage, as well as a simpler method for screening overweight and obesity in children. Objective To determine the diagnostic value of upper arm circumference compared to BMI for detecting overweight and obesity in children aged 6-7 years. Methods This diagnostic study with a cross-sectional design was performed from September to October 2015 at 16 primary schools in Palembang, Indonesia. We measured the heights, weights, and upper arm circumferences, and calculated BMIs of 2,258 children. Receiver-operator characteristic (ROC curve analysis was used to find an optimal upper arm circumference cut-off point to detect overweight and obesity. Diagnostic value was calculated by using a 2x2 table analysis. Results The prevalences of overweight and obesity were 5.8% and 11.7%, respectively. The optimal upper arm circumference cut-off points for detecting overweight in children aged 6-7 years was 185 mm (sensitivity 88.1% and specificity 78.3%, and for obesity was 195 mm (sensitivity 90.15% and specificity 86.65%. Upper arm circumference had a strong correlation with BMI. Conclusion Upper arm circumference measurement is an accurate method fordistinguishing between normoweight, overweight, and obesity in children aged 6-7 years.

    2016-04-01

    With more than 150 million people living within 1 m of high tide future sea level rise is one of the most damaging aspects of warming climate. The latest Intergovernmental Panel on Climate Change report (AR5 IPCC) noted that a 0.5 m rise in mean sea level will result in a dramatic increase the frequency of high water extremes - by an order of magnitude, or more in some regions. Thus the flood threat to the rapidly growing urban populations and associated infrastructure in coastal areas are major concerns for society. Hence, impact assessment, risk management, adaptation strategy and long-term decision making in coastal areas depend on projections of mean sea level and crucially its low probability, high impact, upper range. With probabilistic approach we produce regional sea level projections taking into account large uncertainties associated with Greenland and Antarctica ice sheets contribution. We calculate the upper limit (as 95%) for regional sea level projections by 2100 with RCP8.5 scenario, suggesting that for the most coastlines upper limit will exceed the global upper limit of 1.8 m.

  6. Diagnosis and treatment of upper limb apraxia.

    Dovern, A; Fink, G R; Weiss, P H

    2012-07-01

    Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients' everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients' prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed and ill-treated entity. Based on a systematic literature search, this review summarizes the current tools of diagnosis and treatment strategies for upper limb apraxia. It furthermore provides clinicians with graded recommendations. In particular, a short screening test for apraxia, and a more comprehensive diagnostic apraxia test for clinical use are recommended. Although currently only a few randomized controlled studies investigate the efficacy of different apraxia treatments, the gesture training suggested by Smania and colleagues can be recommended for the therapy of apraxia, the effects of which were shown to extend to activities of daily living and to persist for at least 2 months after completion of the training. This review aims at directing the reader's attention to the ecological relevance of apraxia. Moreover, it provides clinicians with appropriate tools for the reliable diagnosis and effective treatment of apraxia. Nevertheless, this review also highlights the need for further research into how to improve diagnosis of apraxia based on neuropsychological models and to develop new therapeutic strategies.

As the ITER construction phase has started, the procurement of the VV ports has been launched. The VV upper ports will be procured by the Russian Federation Domestic Agency. The main suppliers were selected and the manufacturing design of the first parts is in full progress now. Since the VV is classified at nuclear level N2, the design and manufacture of its components are to be compliant with the French RCC-MR code and regulations for nuclear pressure equipment in France. These regulations make a strong impact to the port design and manufacturing process.

    Full Text Available Background: Although injuries at school are an important issue in public health, environmental factors in schools and school yards have seldom been the focus of school injury research. The goal of our investigation was to examine the effect of environmental factors on school injuries. Methods: Nine comprehensive Finnish schools registered school injuries over a period of two school years. Injuries were classified as being associated with environmental factors, suspected environmental factors, and others. The consensus between two independent classifiers was 81%. Results: A total of 722 injuries were classified. In 11.6% of these injuries, the physical environment factor was evident, and in 28.1% of the injuries, physical environment was suspected of being a contributory risk factor. Thus the physical environment of the school was a contributing factor in over a third (39.7% of injuries occurring in the school, on the school yard or during the journey to or from school. In this study, conducted in Finland, ice on the ground was mentioned most frequently as an environmental risk factor. Conclusions: In Finland, the Nordic weather conditions are not taken into account in the school yard and playground plans as they ought to from the safety point of view. An initiative has been launched on a mandatory wintertime master plan for every school yard.

    Rose, Barbara L; Mansour, Mona; Kohake, Kelli

    2005-12-01

    The Cincinnati School Health Demonstration Project was a 3-year collaboration that evaluated school-linked health services in 6 urban elementary (kindergarten to eighth grade) schools. Partners from the Cincinnati Health Department, Cincinnati Public Schools, Cincinnati Children's Hospital Medical Center, and The Health Foundation of Greater Cincinnati wanted to determine if levels of school-linked care made a difference in student quality of life, school connectedness, attendance, emergency department use, and volume of referrals to health care specialists. School nurses, principals and school staff, parents and students, upper-level managers, and health service researchers worked together over a 2.5-year period to learn about and use new technology to collect information on student health, well-being, and outcome measures. Varying levels of school health care intervention models were instituted and evaluated. A standard model of care was compared with 2 models of enhanced care and service. The information collected from students, parents, nurses, and the school system provided a rich database on the health of urban children. School facilities, staffing, and computer technology, relationship building among stakeholders, extensive communication, and high student mobility were factors that influenced success and findings of the project. Funding for district-wide computerization and addition of school health staff was not secured by the end of the demonstration project; however, relationships among the partners endured and paved the way for future collaborations designed to better serve urban school children in Cincinnati.

  15. Computer vision for shoe upper profile measurement via upper and sole conformal matching

    Science.gov (United States)

    Hu, Zhongxu; Bicker, Robert; Taylor, Paul; Marshall, Chris

    2007-01-01

    This paper describes a structured light computer vision system applied to the measurement of the 3D profile of shoe uppers. The trajectory obtained is used to guide an industrial robot for automatic edge roughing around the contour of the shoe upper so that the bonding strength can be improved. Due to the specific contour and unevenness of the shoe upper, even if the 3D profile is obtained using computer vision, it is still difficult to reliably define the roughing path around the shape. However, the shape of the corresponding shoe sole is better defined, and it is much easier to measure the edge using computer vision. Therefore, a feasible strategy is to measure both the upper and sole profiles, and then align and fit the sole contour to the upper, in order to obtain the best fit. The trajectory of the edge of the desired roughing path is calculated and is then smoothed and interpolated using NURBS curves to guide an industrial robot for shoe upper surface removal; experiments show robust and consistent results. An outline description of the structured light vision system is given here, along with the calibration techniques used.

  16. CT arteriography of the upper abdomen

    1980-04-01

    The technique of CT arteriography was introduced, and CT images of the upper abdomen were explained. Very clear enhancement of parenchyma and vessels (especially portal vein) of the object organs could be obtained by CT arteriography of the upper abdomen, anatomical structures of organs were identified more easily by CT arteriography than by conventional CT, and the amount of information obtained was increased by using CT arteriography. However, the indication of CT arteriography must be limited, because of its complexity that CT arteriography is performed after angiography and involves the invasion of patients' bodies. As described in many reports, CT arteriography is useful for malignant tumors of the liver, and it is worthwhile, especially when surgery for hepatocellular carcinoma is considered. CT arteriography for organs except the liver has not been discussed sufficiently. Therefore, an application of this method for other organs must be decided after consideration of the balance of the amount of information obtained by CT arteriography with invasion to patients.

  17. Temperature Profile of the Upper Mantle

    International Nuclear Information System (INIS)

    Anderson, O.L.

    1980-01-01

    Following the procedure outlined by Magnitsky [1971], thermal profiles of the upper mantle are computed by deriving the thermal gradient from the seismic data given as dv/sub s//drho used along with the values of (dv/sub s//dT9/sub p/ and (dv/sub s//dP)/sub T/ of selected minerals, measured at high temperature. The resulting values of dT/dZ are integrated from 380 km upward toward the surface, where the integrating constant is taken from Akagi and Akimoto's work, T=1400 0 C at 380 km. The resulting geotherms for minerals are used to derive geotherms for an eclogite mantle and a lherzolite mantle, with and without partial melting in the low-velocity zone. The geotherms are all subadiabatic, and some are virtually isothermal in the upper mantle. Some are characterized by a large thermal hump at the lithosphere boundary

  18. Emulating Upper Limb Disorder for Therapy Education

    Directory of Open Access Journals (Sweden)

    Noor Ayuni binti Che Zakaria

    2014-11-01

    Full Text Available Robotics not only contributes to the invention of rehabilitation devices, it can also enhance the quality of medical education. In recent years, the use of patient simulators and part-task trainers in the medical education field has brought meaningful improvements in the training of medical practitioners. Nevertheless, in the context of therapy training for upper limb disorders, trainee therapists still have to engage directly with the patients to gain experience of the rehabilitation of physical diseases. In this work, a high-fidelity part-task trainer that is able to reproduce the stiffness of spasticity and rigidity symptoms of the upper limb, such as those observed in post-stroke patients and Parkinson's disease patients, has been developed. Based on the evaluation carried out by two experienced therapists, the developed part-task trainer is able to simulate different patient cases and help trainee therapists gain pre-clinical experience in a safe and intuitive learning environment.

    2007-01-01

    To define the various causes of nonvariceal upper gastrointestinal bleeding, to outline management modalities and to determine the final outcome of patients. A retrospective analysis of patients presenting with upper gastrointestinal (UGI) bleeding from January 2003 to December 2006 (4 years) was conducted. Patients with endoscopically proven variceal bleeding were excluded. Out of the 120 patients, most of the patients belonged to an age group of more than 50 years (mean 48.5 years). Haematemesis was the most common presentation and Acute Gastric Mucosal Lesion (AGML) was the most frequently encountered lesion. The cause of bleeding was not identified in 10 patients (undetermined group). Twenty-two (18.3%) underwent surgery and we had an overall mortality of 15.8%. AGML being the leading cause can be managed conservatively most of the time. There is a male preponderance and the incidence and mortality increases with advancing age. The undetermined group remains a diagnostic problem. (author)

    2009-01-01

    A 54-year-old male with partial denture underwent stereotactic radiosurgery with an infrared camera-guided system for a metastatic brain tumor arising from lung cancer. Although this method utilizes a biteplate mounted on the upper jaw to detect head movement, the patient only had four teeth in his upper jaw. In order to stabilize the biteplate, the maxillary denture was fixed to the biteplate with an autopolymerizing resin. In addition, the rest-occlusal position of the lower jaw was impressed on the inferior surface of the biteplate with an autopolymerizing resin. To assess reproducibility and stability, the distance between the left and right incus and left and right markers was measured during pre-planning, as well as before and after stereotactic irradiation. Wearing the biteplate ensures the accuracy of radiotherapy planning for the implementation of radiosurgery in patients who have many maxillary teeth missing. However, a large degree of error was observed when the biteplate was removed. (author)

    Full Text Available Abstract Background Motor problems are reported by patients with fibromyalgia (FM. However, the mechanisms leading to alterations in motor performance are not well understood. In this study, upper limb position control during sustained isometric contractions was investigated in patients with FM and in healthy controls (HCs. Methods Fifteen female FM patients and 13 HCs were asked to keep a constant upper limb position during sustained elbow flexion and shoulder abduction, respectively. Subjects received real-time visual feedback on limb position and both tasks were performed unloaded and while supporting loads (1, 2, and 3 kg. Accelerations of the dominant upper limb were recorded, with variance (SD of mean position and power spectrum analysis used to characterize limb position control. Normalized power of the acceleration signal was extracted for three frequency bands: 1–3 Hz, 4–7 Hz, and 8–12 Hz. Results Variance increased with load in both tasks (P 0.001 but did not differ significantly between patients and HCs (P > 0.17. Power spectrum analysis showed that the FM patients had a higher proportion of normalized power in the 1–3 Hz band, and a lower proportion of normalized power in the 8–12 Hz band compared to HCs (P 0.05. The results were consistent for all load conditions and for both elbow flexion and shoulder abduction. Conclusion FM patients exhibit an altered neuromuscular strategy for upper limb position control compared to HCs. The predominance of low-frequency limb oscillations among FM patients may indicate a sensory deficit.

    Full Text Available Introduction: The incidence of tumors of the upper urothelium is high in our country, apart from their relation to specific regions (BEN and PBEN and their frequent bilateralism. Bilateral forms are present in significant percentage and are followed, in most cases, by renal failure, which speaks in favor of conservative surgery, if possible. Objective: The aim of the study was to present epidemiological, pathoanatomical and clinical characteristics of bilateral tumors of the upper urothelium and evaluate the Results of their treatment. Method: Our retrospective study analyzed 12 patients with bilateral tumors of the upper urothelium who were treated in the period from 1992 to 1996, according to their epidemiological, clinical, pathoanatomical and pathohistological characteristics, type of surgical treatment and relevant success. Results: In the observed period, bilateral tumors of the upper urothelium were found in 8.2% of our patients. In the group of 12 patients, 5 females and 7 males, 11 cases were from the region of Balkan Endemic Nephropathy (BEN. Renal failure was recorded in high percentage (66%. Radical surgical treatment - total nephroureterectomy was performed in 9 kidney units, and conservative operation in 15 units. Relapse significantly depended on tumor stage and grade, not on type of surgical treatment in the majority of cases. Five-year survival was 58.33%; major cause of death was associated with further evolution of tumor, recurrence and tumor dissemination, respectively, while renal failure complications were the cause of death in one case. Conclusion: The success of treatment mainly depends on tumor stage and grade and not on type of surgical Method in conservative treatment, but renal failure and its complications are an important risk factor in these patients.

  14. PWR upper/lower internals shield

    Energy Technology Data Exchange (ETDEWEB)

    Homyk, W.A. [Indian Point Station, Buchanan, NY (United States)

    1995-03-01

    During refueling of a nuclear power plant, the reactor upper internals must be removed from the reactor vessel to permit transfer of the fuel. The upper internals are stored in the flooded reactor cavity. Refueling personnel working in containment at a number of nuclear stations typically receive radiation exposure from a portion of the highly contaminated upper intervals package which extends above the normal water level of the refueling pool. This same issue exists with reactor lower internals withdrawn for inservice inspection activities. One solution to this problem is to provide adequate shielding of the unimmersed portion. The use of lead sheets or blankets for shielding of the protruding components would be time consuming and require more effort for installation since the shielding mass would need to be transported to a support structure over the refueling pool. A preferable approach is to use the existing shielding mass of the refueling pool water. A method of shielding was devised which would use a vacuum pump to draw refueling pool water into an inverted canister suspended over the upper internals to provide shielding from the normally exposed components. During the Spring 1993 refueling of Indian Point 2 (IP2), a prototype shield device was demonstrated. This shield consists of a cylindrical tank open at the bottom that is suspended over the refueling pool with I-beams. The lower lip of the tank is two feet below normal pool level. After installation, the air width of the natural shielding provided by the existing pool water. This paper describes the design, development, testing and demonstration of the prototype device.

    The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobinupper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobingastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even

  17. Regional aerosol deposition in human upper airways

    International Nuclear Information System (INIS)

    Swift, D.L.

    1989-01-01

    During the report period significant progress on the quantitative understanding of regional upper airway deposition of airborne particle has been realized. Replicate models of the human upper airways obtained from post-mortem casting of the nasal, oral, pharyngeal, laryngeal and upper tracheal regions and in vivo magnetic resonance imaging (MRI) of the same regions of adults and children have been employed to determine the overall and local deposition characteristics of aerosols in the ultrafine (1--100 μm diameter) and fine (0.8--12 μm diameter) region. Studies have been carried out for both nasal and oral breathing during inspiratory and expiratory flow at constant flow rates representative of rest and states of exercise. The results of these investigations indicate that particles in the size range of ''unattached'' radon progeny (1--3 nm) are deposited in both the nasal and oral passages with high efficiency (60--80%) for both inspiration and expiration, with the nasal deposition being somewhat greater (5--10%) than oral deposition. The effect of flow rate on upper airway deposition for both pathways is not great; data analysis indicates that the deposition for all flow rates from 4--50 liters/minute can be grouped by plotting deposition vs Q- 1/8 , where Q is flow rate, a far weaker dependency than observed for inertial deposition. Diffusional transport is the primary mechanism of deposition, and size dependence can be accounted for by plotting, deposition percent vs D n where D is particle diffusion coefficient and n ranges from 0.5--0.66. 2 refs

    1986-01-01

    Purpose: Preference is given to the strength and thermal insulation of a roof slab thereby ensuring axial size and improving the operationability upon inserting the control rod in the upper shielding body of LMFBR type reactors. Constitution: In an upper shielding body in which a large rotational plug is rotatably mounted to a circular hole formed at an eccentric position of a roof slab, while a small rotational plug is rotatably mounted to a circular hole disposed at an eccentric position of the large rotational plug and the reactor core upper mechanisms are supported on the small rotational plug, heat insulation layers are attached to the inside of the inner circumferential wall of the roof slab and the outer circumferential wall of the large rotational plug. By attaching the heat insulation layers, the heat conduction between the roof slab and the large rotational plug can be suppressed remarkably, by which occurrence of specific heat pass or local generation of large thermal stresses can be avoided even if difference is resulted to the temperature distribution between them. In this way, functions taking advantage of respective features of the roof slab and the small rotational plug can be obtained to achieve the purpose. (Kamimura, M.)

    The next three articles in this issue take a unique approach to discussing volumetric restoration. Robert Glasgold has provided an assessment for each facial region and five different renowned authors (TK, SPS, RF, SML, and EFW) have been asked to speak on a particular volumetric product, of which they are considered an expert, as it applies to the different regions of the face. The articles are broken into the following: (1) upper third which corresponds to the upper eyelid, brow, temple, and forehead; (2) middle third which will cover lower eyelid, cheek, and perioral area; and (3) lower third which discusses the marionette, prejowl, and jawline. Our hope is that by placing differing opinions of experienced authors, organized by facial region together, the reader will have the opportunity to more readily compare the options. The contributing authors and their product area are as follows: Theda Kontis, MD-hyaluronic acid; Steve Smith, MD-calcium hydroxyl appetite; Rebecca Fitzgerald, MD-poly-L lactic acid; Sam Lam, MD-polymethyl methacrylate; and Edwin Williams, MD-Autologous Fat Transfer. If the author included general comments on the product, they are included in the article on the upper face only and are not repeated. Please note that other individuals may also have significantly assisted in the production of these articles, but those listed above are the senior authors.

    Full Text Available Land degradation is a serious problem in the Upper Sekampung Watersheds. This is because the farmers cultivated in steep land to coffee crops without in adequate soil and water conservation practices. The land degradation is mostly caused by erosion. The erosion problem not only stripping the most fertile top soil and decreasing crop production, but also resulting problems in lowland. Therefore, the reorientation land management should be improved to produce agriculture sustainability. The first step is to evaluated land capability this area. The objectives of the research were evaluate land capability of Upper Sekampung Watersheds. The results showed that the Upper Sekampung Watersheds were dominated with class and subclass land capability of III-l2 about 17.630,51 ha (41,58%. All of the constrain for each land capability in this area is erosion hazard, especially land slope. From this research, cultivated land to coffee base crops were allowed in land capability II-l1.e1, III-l2, IV-l3, and VI-l4, with in adequate soil and water conservation practices. In contrary, the land capability of VII-l5 unsuitable for agriculture, they should be a nature or for conservation forest.

    The imaging features of extensive lipofibromatosis presenting in a 1-day-old female infant are reported. This lesion involved her entire right upper limb, extending from the axilla to the palm of the hand. Radiographs showed marked deformity and thinning of all the right upper-limb bones due to pressure effect of soft-tissue enlargement, especially affecting the distal humerus and proximal forearm bones. Magnetic resonance imaging showed a huge soft-tissue mass infiltrating most of the muscles of the entire upper limb, with bony erosion. The mass was largely T1-isointense, moderately T2-hyperintense and showed marked enhancement. There were intra-lesional signal changes consistent with fatty elements. A lesion debulking procedure was performed and the histology was that of lipofibromatosis. The limb was found to be non-viable after the procedure and a subsequent above-elbow amputation was performed. Although the resection margins were not clear, she had no further recurrence over a subsequent 3-year follow-up period. (orig.)

  2. Spacesuit Soft Upper Torso Sizing Systems

    The passive sizing system consists of a series of low-profile pulleys attached to the front and back of the shoulder bearings on a spacesuit soft upper torso (SUT), textile cord or stainless steel cable, and a modified commercial ratchet mechanism. The cord/cable is routed through the pulleys and attached to the ratchet mechanism mounted on the front of the spacesuit within reach of the suited subject. Upon actuating the ratchet mechanism, the shoulder bearing breadth is changed, providing variable upper torso sizing. The active system consists of a series of pressurizable nastic cells embedded into the fabric layers of a spacesuit SUT. These cells are integrated to the front and back of the SUT and are connected to an air source with a variable regulator. When inflated, the nastic cells provide a change in the overall shoulder bearing breadth of the spacesuit and thus, torso sizing. The research focused on the development of a high-performance sizing and actuation system. This technology has application as a suit-sizing mechanism to allow easier suit entry and more accurate suit fit with fewer torso sizes than the existing EMU (Extravehicular Mobility Unit) suit system. This advanced SUT will support NASA s Advanced EMU Evolutionary Concept of a two-sizes-fit-all upper torso for replacement of the current EMU hard upper torso (HUT). Both the passive and nastic sizing system approaches provide astronauts with real-time upper torso sizing, which translates into a more comfortable suit, providing enhanced fit resulting in improved crewmember performance during extravehicular activity. These systems will also benefit NASA by reducing flight logistics as well as overall suit system cost. The nastic sizing system approach provides additional structural redundancy over existing SUT designs by embedding additional coated fabric and uncoated fabric layers. Two sizing systems were selected to build into a prototype SUT: one active and one passive. From manned testing, it

    The number of catastrophic injuries caused by improvised explosive devices in the Afghanistan and Iraq Wars has increased public, legislative, and research attention to upper limb amputation. The Department of Veterans Affairs (VA) has partnered with the Defense Advanced Research Projects Agency and DEKA Integrated Solutions to optimize the function of an advanced prosthetic arm system that will enable greater independence and function. In this special communication, we examine current practices in prosthetic rehabilitation including trends in adoption and use of prosthetic devices, financial considerations, and the role of rehabilitation team members in light of our experiences with a prototype advanced upper limb prosthesis during a VA study to optimize the device. We discuss key challenges in the adoption of advanced prosthetic technology and make recommendations for service provision and use of advanced upper limb prosthetics. Rates of prosthetic rejection are high among upper limb amputees. However, these rates may be reduced with sufficient training by a highly specialized, multidisciplinary team of clinicians, and a focus on patient education and empowerment throughout the rehabilitation process. There are significant challenges emerging that are unique to implementing the use of advanced upper limb prosthetic technology, and a lack of evidence to establish clinical guidelines regarding prosthetic prescription and treatment. Finally, we make recommendations for future research to aid in the identification of best practices and development of policy decisions regarding insurance coverage of prosthetic rehabilitation.

    Velentzas, Athanasios; Halkia, Krystallia

    2018-01-01

    In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the explanandum is a logical consequence of the explanans, which in all cases include at least one scientific law (and/or principle, model or rule) previously presented, as well as statements concerning a specific case or specific conditions. The same structure is also followed in most of the cases in which the textbook authors explain regularities (i.e. laws, rules) as consequences of one or more general law or principle of physics. Finally, a number of the physics laws and principles presented in textbooks are not deduced as consequences from other, more general laws, but they are formulated axiomatically or inductively derived and the authors argue for their validity. Since, as it was found, the scientific explanations presented in the textbooks used in the study have similar structures to the explanations in internationally known textbooks, the findings of the present work may be of interest not only to science educators in Greece, but also to the community of science educators in other countries.

    Full Text Available A new method for the assessment of the upper limb (UL functional state, using a haptic interface is presented. A haptic interface is used as a measuring device, capable of providing objective, repeatable and quantitative data of the UL motion. A patient is presented with a virtual environment, both graphically via a computer screen and haptically via the Phantom Premium 1.5 haptic interface. The setup allows the patient to explore and feel the virtual environment with three of his/her senses; sight, hearing, and most important, touch. Specially designed virtual environments are used to assess the patient’s UL movement capabilities. The tests range from tracking tasks – to assess the accuracy of movement – tracking tasks with added disturbances in a form of random forces – to assess the patient’s control abilities, a labyrinth test – to assess both speed and accuracy, to the last test for measuring the maximal force capacity of the UL.A new method for the assessment of the upper limb (UL functional state, using a haptic interface is presented.

    Upper respiratory tract infections (URTIs) represent the most common acute illnesses in the general population and account for the leading acute diagnoses in the outpatient setting. Given the athlete's expectation to return to activity as soon as possible, the sports medicine physician should be able to accurately diagnose and aggressively treat these illnesses. This article discusses the common pathogens, diagnosis, treatment options, and return-to-play decisions for URTIs, with a focus on the common cold, sinusitis, pharyngitis, and infectious mononucleosis in the athlete.

    Common upper extremity injuries in resistance training athletes include muscle strains, ligament sprains, pectoralis major tendon ruptures, distal biceps tendon ruptures, and chronic shoulder pain and capsulolabral injuries. While each injury is unique in its specific anatomic location and mechanism, each is preventable with proper exercise technique, safety and maintenance of muscle balance. Conservative treatment is the therapeutic modality of choice and these injuries generally resolve with workout modification, appropriate recovery, anti-inflammatory medication, and physical therapy. If conservative treatment fails, surgical intervention is often successful and can return the weightlifter to a level of performance near their pre-injury level.

    The purpose of this paper is to develop a case for the use of performance indicators by upper management to monitor the effectiveness of material management operations at nuclear power plants. The paper establishes that the use of performance indicators is not a pro forma matter. There are specific standards and conditions to which the material management operation must conform for the performance measures to be meaningful. The paper concludes with discussion of the application and use of specific performance indicators. Proper use of selected performance indicators can remove the mystery and uncertainty for management about an aspect of nuclear plant operations that has significant budget implications

    Student-athletes who strive for success in high-level sports while pursuing upper secondary education may be prone to sport and school burnout. This study examined the co-developmental dynamic of sport and school burnout in Finnish adolescent student-athletes (N time 1  = 391; N time 2  = 373) across the first year of upper secondary school using cross-lagged structural equation modeling (SEM). Furthermore, we used sport and school-related achievement goals as predictors of sport and school burnout, namely sport and school-related exhaustion, cynicism, and feelings of inadequacy. The results showed that burnout dimensions in a particular domain were substantially stable within the same domain during the first year of upper secondary school and that school-related exhaustion at the beginning of upper secondary school predicted sport-related exhaustion at the end of the school year. Mastery goals in sport and school were negatively associated with cynicism and feelings of inadequacy within the same domain. Furthermore, performance goals in school were positively associated with school-related cynicism. The results can be used by healthcare professionals for early prevention of student-athletes' burnout. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Upper gastrointestinal (GI) stents are increasingly being used to manage upper GI obstructions. Initially developed for palliative treatment of esophageal cancer, upper GI stents now play an emerging role in benign strictures of the upper GI tract. Because recurrent obstruction and stent-related complications are common, new modifications of stents have been implemented. Self-expandable metal stents (SEMS) have replaced older plastic stents. In addition, newly designed SEMS have been developed to prevent complications. This review provides an overview of the various types, indications, methods, complications, and clinical outcomes of upper GI stents in a number of malignant and benign disorders dividing the esophagus and gastroduodenum.

    In order to clarify the validity of indication criteria of the conservative treatment for perforated upper gastrointestinal tract, a retrospective study was carried out. We enrolled 28 patients with perforation of the gastrointestinal tract who were determined to receive conservative treatment at the time of hospitalization from January 2000 to December 2007. When the following criteria were satisfied, we treated the patients by the conservative treatment after informed consent was gained from them and their families: stable condition of vital signs; peritoneal signs localized in the upper abdomen; and no or slight fluid collection at the Douglas' pouch determined by computed tomography. Patients who showed changes for the worse of peritonitis or increased fluid collection during follow-up were promptly converted to surgery. Six patients were converted to surgery, but all of them were discharged very much improved. We compared patient's data of the conservative treatment group and the converted surgery group at the time of consultation. All data were not statistically different between two groups. If all criteria are satisfied, it seemed that we can start conservative treatment for perforated gastrointestinal tract with careful observation and the system of prompt conversion to operation for patients who showed changes for the worse of peritonitis or increased fluid collection.

    Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia. PMID:28072728

    To measure consumer satisfaction with upper limb prosthetics and provide an enumerated list of design priorities for future developments. A self-administered, anonymous survey collected information on participant demographics, history of and goals for prosthesis use, satisfaction, and design priorities. The questionnaire was available online and in paper format and was distributed through healthcare providers, community support groups, and one prosthesis manufacturer; 242 participants of all ages and levels of upper limb absence completed the survey. Rates of rejection for myoelectric hands, passive hands, and body-powered hooks were 39%, 53%, and 50%, respectively. Prosthesis wearers were generally satisfied with their devices while prosthesis rejecters were dissatisfied. Reduced prosthesis weight emerged as the highest priority design concern of consumers. Lower cost ranked within the top five design priorities for adult wearers of all device types. Life-like appearance is a priority for passive/cosmetic prostheses, while improved harness comfort, wrist movement, grip control and strength are required for body-powered devices. Glove durability, lack of sensory feedback, and poor dexterity were also identified as design priorities for electric devices. Design priorities reflect consumer goals for prosthesis use and vary depending on the type of prosthesis used and age. Future design efforts should focus on the development of more light-weight, comfortable prostheses.

    The aim of this study was to describe a minimally invasive laparoscopic jejunostomy (Lap-J) technique for obstruction due to upper gastrointestinal malignancies and evaluate the nutritional benefit of Lap-J during neoadjuvant chemotherapy (NAC) in cases with obstructing esophageal cancer. Under general anesthesia, the jejunum 20–30 cm distant from the Treitz ligament was pulled out through an extended umbilical laparoscopic incision and a jejunal tube was inserted to 30 cm. The loop of bowel was gently returned to the abdomen and the feeding tube was drawn through the abdominal wall via the left lower incision. The jejunum was then laparoscopically sutured to the anterior abdominal wall. Lap-J was performed in 26 cases. The median operative time was 82 min. The postoperative course was uneventful. Lap-J prior to NAC was not associated with a decrease in body weight or serum total protein during NAC, compared with patients who received NAC without Lap-J. This minimally invasive jejunostomy technique may be particularly useful in patients in whom endoscopic therapy is not feasible due to obstruction from upper gastrointestinal malignancies.

    Purpose. - To study the frequency and risk factors for upper limb lymphedema through a series of patients treated for breast cancer. Patients and methods. - It is a retrospective study about 222 patients treated for breast cancer during the period between February 1993 and December 2003 in Sfax hospitals. Average age was 51 years (27-92 years). Tumour was T2 in 59% of cases. All patients had surgery with lymph node dissection. Infiltrating ductal carcinoma was the most frequent histological type (80% of cases), with predominant SBR II grade (62%). The mean number of removed lymph nodes was 12 (2-33). Axillary lymph node metastasis was detected in 124 patients. Radiotherapy was delivered in 200 patients, including axillary irradiation in 30 cases. The mean follow-up was 68 months (12-120). Results. - Lymphedema appeared in 23% of cases (51 patients), 14 months after surgery (mean period). Lymphedema affected the brachium in 17% of cases, the forearm in 12% of cases and all upper limb in 71% of cases. Fifty percent of patients had rehabilitation. However, improvement of lymphedema was obtained in 18 cases. Parameters predicting lymphedema were studied. Significant risk factors were obesity, infection and a number of removed lymph node above 10. The type of surgery, axillary irradiation and shoulder abduction deficit did not predict lymphedema. Conclusion. - Lymphedema of the arm is a frequent consequence of breast cancer treatment. The risk of lymphedema is correlated with obesity, infection and a number of removed lymph node above 10.

  11. Mammal extinctions in the Vallesian (Upper Miocene)

    Science.gov (United States)

    Agusti, J.; Moya-Sola, S.

    The term Vallesian was created by Crusafont (1950) to designate the first European Mammalian palaeofaunas containing the equid Hipparion, the remainder of the faunas being composed of typical elements coming from the Middle Miocene such as Micromeryx, Euprox, Sansanosmilus, Pseudaelurus, and Listriodon. Thus, the Aragonian-Vallesian boundary does not show a strong change among European Miocene mammalian faunas (Agusti et al., 1984). On the other hand, the Lower Vallesian/Upper Vallesian transition corresponds to a major biotic crisis. This boudnary is characterized by the disappearence of most of the Aragonian artiodactyl forms such as Protragocerus, Miotragocerus, Listriodon, Hyotherium, Parachleusastochoerus, etc. Among the rodents, this crisis affects the family Eomyidae and most of the cricetid and glirid species. On the other hand, a number of eastern elements appear in the area at the same time. This is the case of the suid Schizochoerus and the murid Progonomys. Other eastern forms are Tragoportax, Graecoryx, Adcrocuta, Paramachairodus, Microstonyx, etc. Most of these are typical elements of the next Mammal stage, the Turolian. Thus, whereas the Lower Vallesian fauna has a typical Aragonian composition except for Hipparion. After the Middle Vallesian event, the Upper Vallesian faunas are already largely Turolian in character. The possible factors involved in this extinction event are discussed.

  13. A comparative review of the effectiveness of radon remediation programmes in hospitals, schools and homes in Northamptonshire, UK

    International Nuclear Information System (INIS)

    Denman, A.R.; Phillips, P.S.; Tornberg, R.

    2000-01-01

    In the UK, the National Radiological Protection Board (NRPB) has designated a number of Affected Areas where 1% or more of the homes are above the Action Level of 200 Bqm -3 , including Northamptonshire, with 6.3% of houses above the Action Level. Since 1993, a radon remediation programme in National Health Service properties in Northamptonshire has been undertaken (1). Radon levels both before and after remediation were studied, together with the number of occupants of affected rooms, and their pattern of occupation. The total costs were recorded, including the initial survey to find the affected rooms, and the work done to reduce radon levels, to estimate the total cost per annual dose saved. This method has been extended to domestic properties (2), and schools (3) in Northamptonshire. The results showed that the programmes could be justified when compared to the NRPB initiative to reduce patient dose from dental X-Rays. This paper reviews this work, and provides an updated comparison of the three studies. The domestic series now extends to 65 remediated homes with 156 occupants, and the analysis of the programme now includes the cost of UK Value Added Tax (VAT) at 17.5%, which is payable by the householder on the remediation work. Further, a local survey concluded that the public in county town of Northampton spent on average 72% of their time in their own home, rather than the 50% assumed previously. The remediation costs in all series were reviewed, and individual corrections made for inflation. While the NHS properties and Schools programmes were comprehensive, only 10% householders who discovered raised radon levels have so far proceeded to remediation, despite much local publicity. The collective dose saved annually in Northamptonshire was estimated to be 0.533 man-sieverts in NHS Properties, 4.0 man-sieverts in Schools, and has reached 18 man-sieverts in domestic properties. The domestic programme has the potential to save 690 man-sieverts if all houses

  16. Prospects for an upper Givetian substage

    2001-01-01

    Full Text Available New ammonoid and conodont data from Germany, the Montagne Noire (France and southeastern Morocco document a complex sequence of sedimentary events and faunal changes within an extended Givetian (late Middle Devonian Taghanic Event Interval or Taghanic Biocrisis. Direct association of supposed typical middle Givetian ammonoids, trilobites and corals with upper Givetian marker taxa such as pharciceratids have been found, for example, in Moroccan and French time equivalents of the New York Upper Tully Limestone. The initial and eustatic Taghanic Onlap level is not known to be characterized by the first appearance of any widespread index conodont, goniatite or other taxon. A future upper Givetian substage, therefore, might be based either on the entry of Ozarkodina semialternans or on the first appearance of Schmidtognathus hermanni. The semialternans Zone correlates with a third sedimentary cycle within the Tully Limestone and with the spread of the first Pharciceratidae. Eobeloceratidae (Mzerrebites juvenocostatus and Archoceratidae n. fam. (Atlantoceras. The (Lower hermanni Zone is marked by a post-event transgression which led to a significant conodont radiation and to a further diversification of Pharciceratidae and Eobeloceratidae (Mz. erraticus.

  17. Upper abdominal malignancies (not including esophagus)

    International Nuclear Information System (INIS)

    Rich, Tyvin A.

    1996-01-01

    Objective: This course will give an overview of the role of radiation therapy in the treatment of gastrointestinal malignancies in the upper abdomen, with an emphasis on carcinomas of the stomach, pancreas and biliary tract. For each site, information will be presented related to failure patterns with conventional surgical treatment and the indications for surgery for different stages of disease. The possible uses of radiation therapy as an adjuvant to surgical resection will be discussed as well as the use of radiation therapy alone. In addition, the combination of radiation therapy with chemotherapy will be discussed for each of these sites, as well as the information available at present as to the optimal way to combine chemotherapy with radiation therapy. Radiation therapy is not generally accepted to have a role in the treatment of patients with adenocarcinomas of the stomach. This is related to the fact that gastric cancer has been standardly treated with surgical resection alone, and delivery of high dose radiation therapy to the upper abdomen can be difficult because of the sensitivity of nearby normal tissues. Nonetheless, data on failure patterns suggest that local recurrence is common in patients with disease through the gastric wall and with positive nodes. Although there is some suggestive data to indicate that radiation therapy is effective as an adjuvant, results of an ongoing trial will be necessary for determination of the exact role of radiation therapy. Possible uses of radiation therapy as preoperative therapy or given alone will also be briefly discussed. Radiation therapy has been often used in the treatment of pancreatic adenocarcinomas, either alone or combined with surgical resection. Its use is more common for this site both because of the extremely poor prognosis of standard therapies, and because of the difficulty in performing an adequate surgical resection. Data will be reviewed suggesting that radiation therapy has a role when

    School reintegration programs have been developed to enhance a positive sense of self-worth in a child who has been burned. The premise of these programs is that cognitive and affective education about children with burns will diminish the anxiety of the patient with burns, the patient's family, faculty and staff of the school, and the students. Five principles guide school reentry programs: (1) preparation begins as soon as possible; (2) planning includes the patient and family; (3) each program is individualized; (4) each patient is encouraged to return to school quickly after hospital discharge; and (5) burn team professionals remain available for consultation to the school. Reintegration programs can vary in format depending on patient and/or family need and capability of the burn team, thus allowing flexibility in assisting every child with burns make the transition from hospital patient to normal living.

    Nuclei in the upper-sd shell usually exhibit characteristics of spherical single particle excitations. In the recent years, employment of sophisticated techniques of gamma spectroscopy has led to observation of high spin states of several nuclei near A ≃ 40. In a few of them multiparticle, multihole rotational states coexist with states of single particle nature. We have studied a few nuclei in this mass region experimentally, using various campaigns of the Indian National Gamma Array setup. We have compared and combined our empirical observations with the large-scale shell model results to interpret the structure of these nuclei. Indication of population of states of large deformation has been found in our data. This gives us an opportunity to investigate the interplay of single particle and collective degrees of freedom in this mass region.

    1992-01-01

    The equations describing the interaction of an upper-hybrid pump wave with small low-frequency density perturbations are discussed under assumption that the pump is spatially nonuniform. The conditions for the modulational instability are investigated. Instead of a dispersion relation, describing the growth of perturbations in the case of an uniform pump, in our case of nonuniform pump a differential equation is obtained and from its eigenvalues are found the instability criteria. Taking into account the slow-frequency self-interaction terms some localized solutions similar to dipole vortices are found, but described by analytic functions in all space. It is shown that their characteristic size and speed are determined by the pump intensity and its spatial structure. (au)

  10. Corrosive injuries of the upper gastrointestinal tract

    Directory of Open Access Journals (Sweden)

    Babu Lal Meena

    2017-01-01

    Full Text Available Corrosive injury of the upper gastrointestinal tract is a worldwide clinical problem, mostly occurring in children. Alkaline agents produce deeper injuries whereas acidic agents produce superficial injuries usually. Hoarseness, stridor, and respiratory distress indicate airway injury. Dysphagia, odynophagia, and drooling of saliva suggest esophageal injury whereas abdominal pain, nausea, and vomiting are indicative of stomach injury. X-rays should be done to rule out perforation. Endoscopy is usually recommended in the first 12–48 h although it is safe up to 96 h after caustic ingestion. Endoscopy should be performed with caution and gentle insufflation. Initial management includes getting intravenous access and replacement of fluids. Hyperemia and superficial ulcerations have excellent recovery while deeper injuries require total parenteral nutrition or feeding jejunostomy. Patients suspected of perforation should be subjected to laparotomy. Common complications after corrosive injury are esophageal stricture, gastric outlet obstruction, and development of esophageal and gastric carcinoma.

    Upper respiratory tract infections are frequent in athletes. Mainly of viral origin, they are treated symptomatically. Infectious mononucleosis is associated with an estimated 2% per hundred risk of splenic rupture, which occurs between day four and twenty one of the illness. Therefore return to play guidelines recommend avoiding, exercice during the first twenty one days. Physical exercise seems to influence the immune system, depending on the intensity and length of it. But the relationship between physical exercise and risk of infections remains controversial: some articles showing an increase in risk, whereas others suggesting a certain degree of protection, in athletes. The actual generally accepted working theory is the J-curve proposed by Nieman. This model remains to be formally proven.

  12. Women in Upper Houses: A Global Perspective

    2008-06-01

    Full Text Available In analyses of female representation in lower houses, the adoption of quotas, the electoral system and the religious aspect have been identified as the main explanatory variables. In the case of upper houses, I see a relationship between their political strength and women’s presence in them: when they are weak, the presence of female representatives tends to be larger, when they are strong, women’s presence is smaller. Furthermore, the article shows that an analysis based solely on the number of seats held by women is insufficient for one to gather the true dimensions of their participation in politics. Evaluating the role and expressiveness of the institutions in which they are present is also necessary.

    One of the challenges facing prosthetic designers and engineers is to restore the missing sensory function inherit to hand amputation. Several different techniques can be employed to provide amputees with sensory feedback: sensory substitution methods where the recorded stimulus is not only transferred to the amputee, but also translated to a different modality (modality-matched feedback), which transfers the stimulus without translation and direct neural stimulation, which interacts directly with peripheral afferent nerves. This paper presents an overview of the principal works and devices employed to provide upper limb amputees with sensory feedback. The focus is on sensory substitution and modality matched feedback; the principal features, advantages and disadvantages of the different methods are presented.

    The temperature structure of the upper atmosphere of Uranus at two locations on the planet was determined from observations of the occultation of the star SAO158687 by Uranus on 10 March 1977, carried out at the Kuiper Airborne Observatory. The temperature-pressure relationships obtained from the immersion and emersion data for 7280 A channel show peak-to-peak variations of 45 K for immersion and 35 K for emersion. The mean temperature for both immersion and emersion profiles is about 100 K, which shows that Uranus has a temperature inversion between 0.001 mbar and the 100 mbar level probed by IR measurements. Both profiles show wavelike temperature variations, which may be due to dynamical or photochemical processes.

    2013-09-01

    Homer's Iliad remains a fascinating source of medical history. This epic poem, compiled around 800 BCE, describes several weeks of the last year of the 10-year siege of Troy (Ilion) by the Achaeans. Homer composed the epic by combining and formalizing oral poems, legends, customs, and experiences that originated in the later Mycenaean age (1600-1100 bce). The story centers on the rage of the great warrior Achilles. The Iliad remains the oldest record of Greek medicine and a unique source of surgical history. This study examines the upper extremity injuries described in the Iliad and compares them to those other sites of injury. Copyright © 2013 American Society for Surgery of the Hand.

    Aisha, Nazziwa; Shohaimi, Shamarina; Adam, Mohd Bakri

    2013-09-01

    Bayesian networks are graphical probabilistic models that represent causal and other relationships between domain variables. In the context of medical decision making, these models have been explored to help in medical diagnosis and prognosis. In this paper, we discuss the Bayesian network formalism in building medical support systems and we learn a tree augmented naive Bayes Network (TAN) from gastrointestinal bleeding data. The accuracy of the TAN in classifying the source of gastrointestinal bleeding into upper or lower source is obtained. The TAN achieves a high classification accuracy of 86% and an area under curve of 92%. A sensitivity analysis of the model shows relatively high levels of entropy reduction for color of the stool, history of gastrointestinal bleeding, consistency and the ratio of blood urea nitrogen to creatinine. The TAN facilitates the identification of the source of GIB and requires further validation.

    2010-02-01

    Barium appendicitis (BA) is a rarely seen entity with fewer than 30 reports in the literature. However, it is a known complication of barium imaging. To report a case of BA in a patient whose computed tomography (CT) scan was initially read as foreign body ingestion. An 18-year-old man presented with right lower quadrant pain after upper gastrointestinal imaging 2 weeks prior. A CT scan was obtained of his abdomen and pelvis that revealed a finding that was interpreted as a foreign body at the area of the terminal ileum. A plain X-ray study of the abdomen revealed radiopaque appendicoliths. Pathology confirmed the diagnosis of barium appendicitis. BA is a rare entity and the pathogenesis is unclear. Shorter intervals between barium study and presentation with appendicitis usually correlate with fewer complications. Copyright (c) 2010 Elsevier Inc. All rights reserved.

  1. Back to school: drop-out and return to school among youth in Mexico City

    Directory of Open Access Journals (Sweden)

    Emilio Blanco Bosco

    2014-09-01

    Full Text Available This paper addresses the return to school among youngsters in Mexico City that had dropped out of school at some point between the beginning of elementary school and the end of upper secondary level. More than a quarter of these youngsters returned to school, which supports the idea that quitting school does not equal to the end of the educational career. There is a significant association between the socioeconomic origin and the probability of an individual returning to school, although weaker (and in the opposite direction than correlation with the probability of dropping out. Complex, non-linear patterns were found between the return and the moment when the drop out occurred, which questions mainstream theories about educational decisions. It was also found that an important proportion of those who returned to school completed upper secondary education, particularly remarkable among youngsters of lower social origins. The evidence supports the idea of considering both the effects of the social structure and the individual agency, and particularly to take into account the actors’ rationality.

  2. Late renal function after upper abdominal irradiation

    International Nuclear Information System (INIS)

    Morris, Monica M.; Willett, Christopher G.

    1997-01-01

    Purpose: This study assesses the late renal function and complications following upper abdominal irradiation. Methods and Materials: Eighty-six adult patients were identified who were treated with curative intent to the upper abdomen, received greater than 50% unilateral kidney irradiation to doses of at least 26 Gy, and survived for 1 year or more. Following treatment, the clinical course, blood pressure, addition of anti-hypertensive medications, serum creatinine and creatinine clearance were determined. Creatinine clearance was calculated by the formula: creatinine clearance equals [(140 - age) x (weight in kilograms)] / (72 x serum creatinine), which has a close correlation to creatinine clearances measured by 24 hour urine measurement. The percent change in creatinine clearance from pre-treatment values was analyzed. Mean follow-up was 6.7 years. Seventeen patients were followed for 11 or more years. Results: Of the 16 patients with pre-radiotherapy hypertension, eight required an increase in the number of medications for control and eight required no change in medication. Twenty-one patients developed hypertension in follow-up, 15 of whom required no medication. One patient developed malignant hypertension on the basis of renal artery stenosis. Acute or chronic renal failure was not observed in any patient. The serum creatinine for all 86 patients prior to irradiation was below 2 mg/100 ml; in follow-up it rose to between 2-3 mg/100 ml in five patients. On univariate analysis, older patient age, female sex, pre-existing hypertension and initially abnormal renal function (creatinine clearance <90mg/ml) were significantly correlated with later poor creatinine clearance (<50 mg/ml). Conclusions: After significant unilateral kidney irradiation, patients demonstrated a laboratory trend to increased creatinine and decreased creatinine clearance. With long-term follow-up, these physiologic changes did not appear to translate into a clinically relevant alteration in

    This study is focused on the poorly understood large-scale upper thermospheric wind dynamics in the southern polar cap, auroral, and mid latitudes. The gaps in our understanding of the dynamic high-latitude thermosphere are largely due to the sparseness of thermospheric wind measurements. Using data from current observational facilities, it is unfeasible to construct a synoptic picture of the Southern Hemisphere upper thermospheric winds. However, enough data with wide spatial and temporal coverage have accumulated to construct a meaningful statistical analysis of winds as function of season, magnetic latitude, and magnetic local time. We use long-term data from nine ground-based stations located at different southern high latitudes and three space-based instruments. These diverse data sets possess different geometries and different spatial and solar coverage. The major challenge of the effort is to combine these disparate sources of data into a coherent picture while overcoming the sampling limitations and biases among the datasets. Our preliminary analyses show mutual biases present among some of them. We first address the biases among various data sets and then combine them in a coherent way to construct maps of neutral winds for various seasons. We then validate the fitted climatology against the observational data and compare with corresponding fits of 25 years of simulated winds from the National Center for Atmospheric Research Thermosphere-Ionosphere-Electrodynamics General Circulation Model. This study provides critical insight into magnetosphere-ionosphere-thermosphere coupling and sets a necessary benchmark for validating new observations and tuning first-principles models.

Cancers of the esophagus, stomach, pancreas, liver, and biliary tree have dismal 5-year survival, and very modest improvements in this rate have been made in recent times. Oncolytic viruses are being developed to address these malignancies, with a focus on high safety profiles and low off-target toxicities. Each viral platform has evolved to enhance oncolytic potency and the clinical response to either single-agent viral therapy or combined viral treatment with radiotherapy and chemotherapy. A panel of genomic alterations, chimeric proteins, and pseudotyped capsids are the breakthroughs for vector success. This article revisits developments for each viral platform to each tumor type, in an attempt to achieve maximum tumor selectivity. From the bench to clinical trials, the scope of this review is to highlight the beginnings of translational oncolytic virotherapy research in upper gastrointestinal tract malignancies and provide a bioengineering perspective of the most promising platforms.

    Probiotics may improve a person's health by regulating their immune function. Some trials have shown that probiotic strains can prevent respiratory infections. Even though the previous version of our review showed benefits of probiotics for acute upper respiratory tract infections (URTIs), several new studies have been published. To assess the effectiveness and safety of probiotics (any specified strain or dose), compared with placebo, in the prevention of acute URTIs in people of all ages, who are at risk of acute URTIs. We searched CENTRAL (2014, Issue 6), MEDLINE (1950 to July week 3, 2014), EMBASE (1974 to July 2014), Web of Science (1900 to July 2014), the Chinese Biomedical Literature Database, which includes the China Biological Medicine Database (from 1978 to July 2014), the Chinese Medicine Popular Science Literature Database (from 2000 to July 2014) and the Masters Degree Dissertation of Beijing Union Medical College Database (from 1981 to July 2014). We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for completed and ongoing trials on 31 July 2014. Randomised controlled trials (RCTs) comparing probiotics with placebo to prevent acute URTIs. Two review authors independently assessed the eligibility and quality of trials, and extracted data using the standard methodological procedures expected by The Cochrane Collaboration. We included 13 RCTs, although we could only extract data to meta-analyze 12 trials, which involved 3720 participants including children, adults (aged around 40 years) and older people. We found that probiotics were better than placebo when measuring the number of participants experiencing episodes of acute URTI [at least one episode: odds ratio (OR): 0.53; 95% CI = 0.37-0.76, P school absence (OR: 0.10; 95% CI = 0.02-0.47, very low quality evidence). Probiotics and placebo were similar when measuring the rate ratio of episodes of acute URTI (rate ratio: 0

  15. Upper bounds on superpartner masses from upper bounds on the Higgs boson mass.

    Cabrera, M E; Casas, J A; Delgado, A

    2012-01-13

    The LHC is putting bounds on the Higgs boson mass. In this Letter we use those bounds to constrain the minimal supersymmetric standard model (MSSM) parameter space using the fact that, in supersymmetry, the Higgs mass is a function of the masses of sparticles, and therefore an upper bound on the Higgs mass translates into an upper bound for the masses for superpartners. We show that, although current bounds do not constrain the MSSM parameter space from above, once the Higgs mass bound improves big regions of this parameter space will be excluded, putting upper bounds on supersymmetry (SUSY) masses. On the other hand, for the case of split-SUSY we show that, for moderate or large tanβ, the present bounds on the Higgs mass imply that the common mass for scalars cannot be greater than 10(11)  GeV. We show how these bounds will evolve as LHC continues to improve the limits on the Higgs mass.

    We sought to understand how polymicrobial colonization varies during health, viral upper respiratory infection (URI) and acute upper respiratory bacterial infection to understand differences in infection-prone vs. non-prone patients. Nasopharyngeal (NP) samples were collected from 74 acute otitis media (AOM) infection-prone and 754 non-prone children during 2094 healthy visits, 673 viral URI visits and 631 AOM visits. Three otopathogens Streptococcus pneumoniae (Spn), Nontypeable Haemophilus influenzae (NTHi), and Moraxella catarrhalis (Mcat) were identified by culture. NP colonization rates of multiple otopathogens during health were significantly lower than during viral URI, and during URI they were lower than at onset of upper respiratory bacterial infection in both AOM infection-prone and non-prone children. AOM infection-prone children had higher polymicrobial colonization rates than non-prone children during health, viral URI and AOM. Polymicrobial colonization rates of AOM infection-prone children during health were equivalent to that of non-prone children during viral URI, and during viral URI were equivalent to that of non-prone during AOM infection. Spn colonization was positively associated with NTHi and Mcat colonization during health, but negatively during AOM infection. The infection-prone patients more frequently have multiple potential bacterial pathogens in the NP than the non-prone patients. Polymicrobial interaction in the NP differs during health and at onset of infection. Copyright © 2017 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

We speculated that forcible maximum opening of the mouth by using a mouth prop triggers this asphyxia by affecting the upper airway. Therefore, we assessed the morphological changes of the upper airway following maximal opening of the mouth. In 13 healthy adult volunteers, the sagittal diameter of the upper airway on lateral cephalogram was measured between the two conditions; closed mouth and maximally open mouth. The dyspnea in each state was evaluated by a visual analog scale. In one subject, a computed tomograph (CT was taken to assess the three-dimensional changes in the upper airway. A significant difference was detected in the mean sagittal diameter of the upper airway following use of the prop (closed mouth: 18.5 ± 3.8 mm, maximally open mouth: 10.4 ± 3.0 mm. All subjects indicated upper airway constriction and significant dyspnea when their mouth was maximally open. Although a CT scan indicated upper airway constriction when the mouth was maximally open, muscular compensation was admitted. Our results further indicate that the maximal opening of the mouth narrows the upper airway diameter and leads to dyspnea. The use of a prop for the patient who has communication problems or poor neuromuscular function can lead to asphyxia. When the prop is used for patient refusal in dentistry, the respiratory condition should be monitored strictly, and it should be kept in mind that the “sniffing position” is effective for avoiding upper airway

Variations of temperature are the key determinant for the distribution of RHI, followed by variations of the water vapor mixing ratio. Multiple humidity modes, generated by mixing of different air masses, may contribute to the overall distribution of RHI, in particular below ice saturation. The fraction of air that is supersaturated with respect to ice is mainly determined by the distribution of temperature. The nucleation of ice in cirrus clouds determines the highest relative humdity that can be measured outside of cirrus clouds.

  6. Upper pinch radius limit in EXTRAP

    International Nuclear Information System (INIS)

    Lehnert, B.

    1989-12-01

    A simple static equilibrium model of the Z-pinch is considered where a hot plasma core is surrounded by a cold-mantle (gas blanket). The pinch radius, defined as the radial extension of the fully ionized plasma core, is uniquely determined by the plasma particle. momentum and heat balance equations. In Extrap configurations an octupole field is introduced which imposes a magnetic separatrix on Z-pinch geometry. This makes the conditions for Extrap equilibrium 'overdetermined' when the characteristic pinch radium given by the plasma parameters tends to exceed the characteristic radius of the magnetic separatrix. In this case no conventional pinch equilibrium can exist, and part of the current which is forced into the plasma discharge by external sources must be channelled outside of the separatrix, i.e. into the surrounding support structure of the Extrap conductors and the vessel walls. A possibly existing bootstrap current in the plasma boundary layer is further expected to be 'scraped off' in this case. The present paper gives some illustrations of the marginal case of this upper pinch radius limit, in a state where the pinch current is antiparallel to the external rod currents which generate the octupole field.

A retrospective review was performed for cases of LWD after UB presenting between 2003 and 2009, and then a prospective comparative study was performed between February 2009 and March 2013. For the comparison, subjects were divided into two groups based on intraoperative assessment of lateral wound tension (same technique and surgeon). Group 1 received 1-3 orbicularis/subcutaneous buried sutures (6-0 polyglactin) before interrupted 6-0 nylon skin closure. Group 2 underwent skin closure only. Subjects, who had re-operation, skin healing disorders, and incomplete follow-up (LWD with a mean age of 36.2 years in the audit (2003-2009). The prospective study included 68 subjects (68/293, 23.2%) in Group 1 and 225 in Group 2. Gender and simultaneous forehead and eyebrow procedures were similar between groups (P = 0.3 and P = 0.4 respectively). Group 1 was statistically significantly younger at mean age of 41.4 years, compared to Group 2 at 56.1 years (P = 0.000). The frequency of LWD significantly (P = 0.04) decreased to 0.3% (1/293). In the presence of wound tension on skin closure (intraoperative assessment), tension relieving buried orbicularis/subcutaneous 6-0 polyglactin suturing of the lateral UB incision could prevent LWD.

    Full Text Available Background: Congenital hand anomalies are numerous and markedly variant. Their significance is attributed to the frequent occurrence and their serious social, psychological and functional impacts on patient's life. Patients and Methods: This is a follow-up study of 64 patients with hand anomalies of variable severity. All patients were presented to Plastic Surgery Department of Sohag University Hospital in a period of 24 months. Results: This study revealed that failure of differentiation and duplication deformities were the most frequent, with polydactyly was the most common anomaly encountered. The mean age of presentation was 6 years and female to male ratio was 1.46:1. Hand anomalies were either isolated, associated with other anomalies or part of a syndrome. Conclusion: Incidence of congenital hand anomalies in Upper Egypt is difficult to be estimated due to social and cultural concepts, lack of education, poor registration and deficient medical survey. Management of hand anomalies should be individualised, carefully planned and started as early as possible to achieve the best outcome.

    During the current report experimental studies of upper respiratory deposition of radon progeny aerosols and stimulant aerosols were carried out in replicate casts of nasal and oral passages of adults and children. Additionally, preliminary studies of nasal passage deposition of unattached Po{sup 218} particles was carried out in four human subjects. Data on nasal inspiratory deposition in replicate models of adults and infants from three collaborating laboratories were compared and a best-fit curve of deposition efficiency for both attached and unattached particles was obtained, showing excellent inter-laboratory agreement. This curve demonstrates that nasal inspiratory deposition of radon progeny is weakly dependent upon flow rate over physiologically realistic ranges of flow, does not show a significant age effect, and is relatively independent of nasal passage dimensions for a given age range. Improved replicate models of the human adult oral passage extending to the mid-trachea were constructed for medium and higher flow mouth breathing states; these models were used to assess the deposition of unattached Po{sup 218} particles during oronasal breathing in the oral passage and demonstrated lower deposition efficiency than the nasal passage. Measurements of both Po{sup 218} particle and attached fraction particle size deposition were performed in replicate nasal passage of a four week old infant. 5 refs., 1 fig.

    Laboratory experimental studies were carried out to investigate the factors influencing the deposition of aerosols ranging in size from 1 nm to 10 [mu]m in the human nasal, oral, pharyngeal and laryngeal airways. These experimental studies were performed in replicate upper airway physical models and in human volunteer subjects. New replicate models of the oral passage of an infant, the oral passage of an adult at two openings and the combined nasal and oral airways of an adult were constructed during the period, adding to the existing models of adult, child and infant nasal and oral airways models. Deposition studies in the adult oral and adult nasal models were performed under simulated cyclic flow conditions with 1 nm particles to compare with previously measured constant flow studies. Similar studies with inertial particles (1--10 [mu]m diameter) were performed with the adult nasal model; in both instances, results with cyclic flow were similar to constant flow results using a simple average flow rate based on inspiratory volume and time of inspiration. Human subject studies were performed with particle sizes 5--20 nm for nasal inspiration; preliminary analysis shows good agreement with model studies at several representative flow rates. Nasal inspiratory inertial deposition of 1--4 [mu]m diameter particles was measured in several adults as a function of airway dimensions; dimensional changes of the valve area by decongestion did not produce concomitant deposition changes.

    To investigate the role of hand dominance in common upper extremity musculoskeletal disorders (UEMSD) in a population study. The target population consisted of a representative sample of people aged 30 years or older residing in Finland during 2000-2001. Of the 7977 eligible subjects, 6254 (78.4%) were included in the study. The prevalence of UEMSD was as follows: rotator cuff tendinitis 3.8%, bicipital tendinitis 0.5%, lateral epicondylitis 1.1%, medial epicondylitis 0.3%, carpal tunnel syndrome (CTS) 3.8%, and surgery due to CTS 1.3%. CTS was 2.5 times as prevalent in women as men, whereas the other UEMSD were as common in both sexes. Rotator cuff and bicipital tendinitis and medial epicondylitis were more prevalent in the dominant arm only in women, whereas lateral epicondylitis was more prevalent in the dominant elbow in both sexes. The higher prevalence of rotator cuff and bicipital tendinitis in the dominant side persisted beyond working age. The prevalence of CTS did not differ by hand dominance. Dominant hand had been operated more frequently for CTS in women. Our findings show that UEMSD are more prevalent in the dominant than nondominant arm mainly in women. For shoulder tendinitis, the difference persists throughout adult age. Physical load factors may have long-lasting effects on the shoulder and they may play a greater role in women than men.

Data on nasal inspiratory deposition in replicate models of adults and infants from three collaborating laboratories were compared and a best-fit curve of deposition efficiency for both attached and unattached particles was obtained, showing excellent inter-laboratory agreement. This curve demonstrates that nasal inspiratory deposition of radon progeny is weakly dependent upon flow rate over physiologically realistic ranges of flow, does not show a significant age effect, and is relatively independent of nasal passage dimensions for a given age range. Improved replicate models of the human adult oral passage extending to the mid-trachea were constructed for medium and higher flow mouth breathing states; these models were used to assess the deposition of unattached Po 218 particles during oronasal breathing in the oral passage and demonstrated lower deposition efficiency than the nasal passage. Measurements of both Po 218 particle and attached fraction particle size deposition were performed in replicate nasal passage of a four week old infant. 5 refs., 1 fig

    Full Text Available Radiogrammetry is radiological method of bone mineral density quantification. Besides giving an insight in diagnostics and evolution of metabolic bone disorders (osteoporosis, osteomalacia, osteitis deformans- Paget's disease, it can also explain some specific biomechanical characteristics of bone structures. The aim of this study is to evaluate the significance and perspectives of radiogrammetry as a scientific model for further inquiry of skeletal system. The work demonstrates mathematical parameters (Ca-Cortical area, CI- Cortical index, GI- Garn's index, ESI- Exton Smith's index of upper limb long bones (humerus, radius, ulna. Two standard radiological projections of bones were taken: antero-posterior (AP and latero-lateral (LL. Correlation with metacarpal and lower limb bones was also performed. The value of the cortical area of humerus is significantly higher comparing with the two other examined bones (Xmean 2,2443 cm2, p < 0.01. Radial bone has the highest values of the relational mathematical parameters, which implicates its higher strength by volumetric unit concerning humerus and ulna. Despite the development of contemporary osteometric procedures (ultrasound densitometry, dual X-ray absorptiometry, digital X-ray radiogrammetry, the classical radiogrammetry sustains its important role in diagnostics of metabolic bone disorders and it can be successfully used for biomechanical inquiry of skeletal system.

    Selective upper airway stimulation (sUAS) of the hypoglossal nerve is a useful therapy to treat patients with obstructive sleep apnea. Is it known that multiple obstructions can be solved by this stimulation technique, even at the retropalatal region. The aim of this study was to verify the palatoglossus coupling at the soft palate during stimulation. Single-center, prospective clinical trail. Twenty patients who received an sUAS implant from April 2015 to April 2016 were included. A drug-induced sedated endoscopy (DISE) was performed before surgery. Six to 12 months after activation of the system, patients' tongue motions were recorded, an awake transnasal endoscopy was performed with stimulation turned on, and a DISE with stimulation off and on was done. Patients with a bilateral protrusion of the tongue base showed a significantly increased opening at the retropalatal level compared to ipsilateral protrusions. Furthermore, patients with a clear activation of the geniohyoid muscle showed a better reduction in apnea-hypopnea index. A bilateral protrusion of the tongue base during sUAS seems to be accompanied with a better opening of the soft palate. This effect can be explained by the palatoglossal coupling, due to its linkage of the muscles within the soft palate to those of the lateral tongue body. 4 Laryngoscope, 127:E378-E383, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    Savastano, S.; Feltrin, G.P.; Miotto, D.; Chiesura-Corona, M.; Rubaltelli, L.; Candiani, F.

    Fourteen cases of upper gastrointenstinal bleeding (UGIB) were reviewed: 6 (group A) were caused by pancreatitis, 3 (group B) by hemobilia, and 5 (group C) by rupture of esophageal varices due to arterioportal shunts. Elective endoscopy carried out in 7 patients in groups A and B was negative; in 2 actively bleeding patients in group A emergency endoscopy could not detect the source of hemorrhage. Endoscopy was carried out in 4 patients in group C for diagnosis and sclerosis, but severe hemorrhage recurred in spite of treatment. Ultrasonography (US) and computed tomography (CT) were carried out prior to angiography in 5 and 4 patients, respectively, and always suggested a parenchymal lesion. All patients underwent angiography. Transcatheter control of the hemorrhage was attempted as an emergency in 2 patients (as a presurgical step in one); elective embolization was the treatment of choice for 8 patients, with good results in 6. This study suggests the usefulness of US and CT both in the detection of parenchymal lesions causing UGIB not clarified by endoscopy, and in the selection of patients for angiographic treatment.

    Viktor Hendrik Koelzer

    2014-08-01

    Full Text Available The basis of personalized medicine in oncology is the prediction of an individual’s risk of relapse and death from disease. The presence of tumor budding (TB at the tumor-host interface of gastrointestinal cancers has been recognized as a hallmark of unfavorable disease biology. TB is defined as the presence of dedifferentiated cells or small clusters of up to five cells at the tumor invasive front and can be observed in aggressive carcinomas of the esophagus, stomach, pancreas, ampulla, colon and rectum. Presence of TB reproducibly correlates with advanced tumor stage, frequent lymphovascular invasion, nodal and distant metastasis. The UICC has officially recognized TB as additional independent prognostic factor in cancers of the colon and rectum. Recent studies have also characterized TB as a promising prognostic indicator for clinical management of esophageal squamous cell carcinoma, adenocarcinoma of the gastro-esophageal junction and gastric adenocarcinoma. However, several important issues have to be addressed for application in daily diagnostic practice: 1 Validation of prognostic scoring systems for tumor budding in large, multi-center studies 2 Consensus on the optimal assessment method 3 Inter-observer reproducibility. This review provides a comprehensive analysis of TB in cancers of the upper gastrointestinal tract including critical appraisal of perspectives for further study.

    Cyberbullying is a relatively new form of bullying, with both similarities and differences to traditional bullying. While earlier research has examined associations between school-contextual characteristics and traditional bullying, fewer studies have focused on the links to students' involvement in cyberbullying behavior. The aim of the present study is to assess whether school-contextual conditions in terms of teachers' ratings of the school leadership are associated with the occurrence of cyberbullying victimization and perpetration among students. The data are derived from two separate data collections performed in 2016: The Stockholm School Survey conducted among students in the second grade of upper secondary school (ages 17-18 years) in Stockholm municipality, and the Stockholm Teacher Survey which was carried out among teachers in the same schools. The data include information from 6067 students distributed across 58 schools, linked with school-contextual information based on reports from 1251 teachers. Cyberbullying victimization and perpetration are measured by students' self-reports. Teachers' ratings of the school leadership are captured by an index based on 10 items; the mean value of this index was aggregated to the school level. Results from binary logistic multilevel regression models show that high teacher ratings of the school leadership are associated with less cyberbullying victimization and perpetration. We conclude that a strong school leadership potentially prevents cyberbullying behavior among students.

    Full Text Available Purpose : To study the association of various risk factors and epidemiological variables of mycotic keratitis treated at a tertiary referral hospital of upper Assam. Materials and Methods: In this hospital-based prospective study a total of 310 consecutive corneal ulcer cases attending the ophthalmology outpatient department of Assam Medical College were enrolled between April 2007 and March 2009. After clinical and slit-lamp biomicroscopic examination in all suspected cases, smears and culture examination for fungus was done to establish the etiology. Demographic information and associated probable risk factors of individual cases were noted in a predesigned questionnaire. Results: In 188 (60.6% cases fungal etiology could be established. Out of them 67.6% were males. The most commonly affected age group was 41-50 years (25.5%. The maximum (23.4% cases were reported during the paddy harvesting season in Assam (January and February. Fungal element could be demonstrated in 65.2% cases in direct potassium hydroxide (KOH mount. The commonest predisposing factor was corneal injury (74.5%. While diabetes was a significant systemic predisposing factor in mixed bacterial and fungal infections in 11.1% cases, blocked naso-lacrimal duct was the local predisposing factor in 11.1% of cases. Fusarium solani (25% was the commonest isolate followed by Aspergillus species (19%, Curvularia species (18.5% and Penicillium species (15.2%. Yeasts were isolated in 2.7% (n=5 cases. Conclusions : Ocular trauma was the commonest cause of fungal corneal ulcer in Assam and Fusarium solani was the commonest species responsible for it. Most of the mycotic ulcer cases come from rural areas including the tea gardens.

  9. Sensory feedback for upper limb prostheses.

    Hsiao, Steven S; Fettiplace, Michael; Darbandi, Bejan

    2011-01-01

    In this chapter, we discuss the neurophysiological basis of how to provide sensory feedback to users with an upper limb prosthesis and discuss some of the theoretical issues that need to be considered when directly stimulating neurons in the somatosensory system. We focus on technologies that are currently available and discuss approaches that are most likely to succeed in providing natural perception from the artificial hand to the user. First, we discuss the advantages and disadvantages of providing feedback by stimulating directly the remaining afferents that originally innervated the arm and hand. In particular, we pay close attention to the normal functional roles that the peripheral afferents play in perception. What are the consequences and implications of stimulating these afferents? We then discuss whether it is reasonable to stimulate neurons in the ascending pathways that carry the information from the afferents to the cortex or directly in neurons in the primary somatosensory cortex. We show that for some modalities there are advantages for stimulating in the spinal cord, while for others it is advantageous to stimulate directly in the somatosensory cortex. Finally, we discuss results from a current experiment in which we used electrical stimuli in primary somatosensory cortex to restore the percept of the intensity of a mechanical probe indented into the hand. The results suggest that the simple percept of stimulus intensity can be provided to the animal from a single finger using four electrodes. We propose that significantly more electrodes will be needed to reproduce more complex aspects of tactile perception. Copyright © 2011 Elsevier B.V. All rights reserved.

  10. Upper airway muscles awake and asleep.

    Science.gov (United States)

    Sériès, Frédéric

    2002-06-01

    Upper airway (UA) structures are involved in different respiratory and non-respiratory tasks. The coordination of agonist and antagonist UA dilators is responsible for their mechanical function and their ability to maintain UA patency throughout the respiratory cycle. The activity of these muscles is linked with central respiratory activity but also depends on UA pressure changes and is greatly influenced by sleep. UA muscles are involved in determining UA resistance and stability (i.e. closing pressure), and the effect of sleep on these variables may be accounted for by its effect on tonic and phasic skeletal muscle activities. The mechanical effects of UA dilator contraction also depend on their physiological properties (capacity to generate tension in vitro, activity of the anaerobic enzymatic pathway, histo-chemical characteristics that may differ between subjects who may or may not have sleep-related obstructive breathing disorders). These characteristics may represent an adaptive process to an increased resistive loading of these muscles. The apparent discrepancy between the occurrence of UA closure and an increased capacity to generate tension in sleep apnea patients may be due to a reduction in the effectiveness of UA muscle contraction in these patients; such an increase in tissue stiffness could be accounted for by peri-muscular tissue characteristics. Therefore, understanding of UA muscle physiological characteristics should take into account its capacity for force production and its mechanical coupling with other UA tissues. Important research goals for the future will be to integrate these issues with other physiological features of the disease, such as UA size and dimension, histological characteristics of UA tissues and the effect of sleep on muscle function. Such integration will better inform understanding of the role of pharyngeal UA muscles in the pathophysiology of the sleep apnea/hypopnea syndrome.

    2016-12-01

    Upper respiratory tract diseases in athletes are a very common medical problem. Training conditions in different sports disciplines increase the risk of upper respiratory disease. Epidemiological evidence suggests that heavy acute or chronic exercise is related to an increased incidence of upper respiratory tract infections in athletes. Regular physical exercise at high intensity may lead to transient immunosuppression due to high prevalence of allergic diseases in athletes. Regardless of the cause they can exclude athletes from the training program and significantly impair their performance. In the present work, the most common upper respiratory tract diseases in athletes taking into account the disciplines in which they most often occur were presented. The focus was laid on symptoms, diagnostic methods and pharmacotherapy. Moreover, preventive procedures which can help reduce the occurrence of upper respiratory tract disease in athletes were presented. Management according to anti-doping rules, criteria for return to training and competition as an important issues of athlete's health were discussed.

    Full Text Available Based on the petrological study, according to single factor analysis and multifactor comprehensive mapping method, the quantitative lithofacies palaeogeography of the Upper Permian Changxing Stage of the Middle and Upper Yangtze Region was studied. The Changxing Stage in the Middle and Upper Yangtze Region is mainly composed of carbonate rocks; in addition, clastic and siliceous rocks occur with rare coals and pyroclastic rocks. Lithofacies can be divided into five types, including clastic rock assemblage, clastic rock–limestone assemblage, limestone assemblage, limestone–siliceous rock assemblage, and siliceous rock–clastic rock assemblage. Four fundamental ecological types and five fossil assemblages were recognized in the Changxing Stage. On the basis of the petrological and palaeoecological study, eight single factors were chosen including thickness, content of marine rocks, content of shallow water carbonate rocks, content of bioclasts with limemud matrix, content of bioclasts with sparry cement, distribution of reefs, content of thin bedded siliceous rocks and content of deep water sedimentary rocks. And eight single factor maps and one lithofacies paleogeographic map of the Changxing Stage were compiled. Paleoenvironments from west to east include an erosional area, fluvial plain, clastic platform, carbonate platform and reefs that developed there, slope and basin, low energy organic banks, and high energy organic banks. Sedimentary environments have an obvious control on the development of the source rocks, and the excellent source rocks are developed in the Dalong Formation. Changxing Stage reservoirs should be dominated by the reef and platform surrounding the Guangyuan–Liangping Basin rim area, and is the most favorable exploration area of the reef petroleum reservoirs of the Changxing Formation.

    Two-dimensional simulations of hot Jupiter upper atmospheres including the planet's magnetic field are presented. The goal is to explore magnetic effects on the layer of the atmosphere that is ionized and heated by stellar EUV radiation, and the imprint of these effects on the Lyα transmission spectrum. The simulations are axisymmetric, isothermal, and include both rotation and azimuth-averaged stellar tides. Mass density is converted to atomic hydrogen density through the assumption of ionization equilibrium. The three-zone structure—polar dead zone (DZ), mid-latitude wind zone (WZ), and equatorial DZ—found in previous analytic calculations is confirmed. For a magnetic field comparable to that of Jupiter, the equatorial DZ, which is confined by the magnetic field and corotates with the planet, contributes at least half of the transit signal. For even stronger fields, the gas escaping in the mid-latitude WZ is found to have a smaller contribution to the transit depth than the equatorial DZ. Transmission spectra computed from the simulations are compared to Hubble Space Telescope Space Telescope Imaging Spectrograph and Advanced Camera for Surveys data for HD 209458b and HD 189733b, and the range of model parameters consistent with the data is found. The central result of this paper is that the transit depth increases strongly with magnetic field strength when the hydrogen ionization layer is magnetically dominated, for dipole magnetic field B {sub 0} ≳ 10 G. Hence transit depth is sensitive to magnetic field strength, in addition to standard quantities such as the ratio of thermal to gravitational binding energies. Another effect of the magnetic field is that the planet loses angular momentum orders of magnitude faster than in the non-magnetic case, because the magnetic field greatly increases the lever arm for wind braking of the planet's rotation. Spin-down timescales for magnetized models of HD 209458b that agree with the observed transit depth

    2008-04-01

    This study prospectively assessed the importance of individual conditions and computer use during school or work and leisure time as risk factors for self-reported generally reduced productivity due to musculoskeletal complaints among young adults with musculoskeletal symptoms in the neck or upper extremities. A cohort of 2914 young adults (18-25 years, vocational school and college or university students) responded to an internet-based questionnaire concerning musculoskeletal symptoms related to individual conditions and computer use during school or work and leisure time that possibly affected general productivity. Prevalence ratios (PR) were used to assess prospective risk factors for generally reduced productivity. The selected study sample (N=1051) had reported neck or upper-extremity symptoms. At baseline, 280 of them reported reduced productivity. A follow-up of the 771 who reported no reduced productivity was carried out after 1 year. Risk factors for self-reported generally reduced productivity for those followed-up were symptoms in two or three locations or dimensions for the upper back or neck and the shoulders, arms, wrists, or hands [PR 2.30, 95% confidence interval (95% CI) 1.40-3.78], symptoms persisting longer than 90 days in the shoulders, arms, wrists, or hands (PR 2.50, 95% CI 1.12-5.58), current symptoms in the shoulders, arms, wrists, or hands (PR 1.78, 95% CI 1.10-2.90) and computer use 8-14 hours/week during leisure time (PR 2.32, 95% CI 1.20-4.47). A stronger relationship was found if three or four risk factors were present. For women, a relationship was found between generally reduced productivity and widespread and current symptoms in the upper extremities. The main risk factors for generally reduced productivity due to musculoskeletal symptoms among young adults in this study were chronic symptoms in the upper extremities and widespread symptoms in the neck and upper extremities.

    2016-01-01

    Laser resurfacing, performed at the same time as blepharoplasty, has most commonly been applied to the lower eyelid skin but can effectively be used on the upper eyelid to reduce rhytidosis and improve skin quality. The authors evaluate the safety and efficacy of this procedure. Fractional CO2 laser resurfacing was performed in conjunction with incisional upper blepharoplasty. The ultrapulsed laser energy was applied to the sub-brow skin, the upper medial canthal skin, and the pretarsal skin in 30 patients. Photos were obtained preoperatively and at 3 months. All patients demonstrated reduction in upper eyelid rhytidosis without any serious complications. Independent rhytidosis grading (0-4) showed a mean improvement of 42%. One patient experienced wound dehiscence that satisfactorily resolved without intervention. Upper eyelid laser resurfacing is effective and can be safely performed at the same time as upper blepharoplasty. This approach reduces or eliminates the need for medial incisions to address medial canthal skin redundancy and rhytidosis and it directly treats upper eyelid wrinkles on residual eyelid and infra-brow skin during blepharoplasty.

    To analyze high risk factors of postoperative upper gastrointestinal (GI) bleeding after neurosurgery so as to give guidance for prevention of GI bleeding. A questionnaire was developed to investigate the medical records of 1500 patients who were hospitalized and underwent neurosurgical operations in 1997. Logistic regression analysis was made. 1430 valid questionnaires were obtained. Postoperative upper GI bleeding occurred in 75 patients (5.24%). The incidence of upper GI bleeding were 6.64% (54/813) in the male patients and 3.40% (21/617) in the female persons (P = 0.007); 9.88% (41/415) in those aged > 50 and 3.35% in those aged hematoma, intraventricular hemorrhage, subdural hematoma, and extradural hematoma were 15.7%, 10.0%, 6.00%, and 2.94% respectively (P = 0.02). The incidence of upper GI bleeding of the patients with tumors of fourth ventricle of cerebrum, brainstem, cerebral hemisphere, and sellar hypothalamus were 15.79% (3/19), 7.89%, 5.71%, and 3.74% respectively. In the emergent cases, the incidence of upper GI bleeding was higher in those with hypertension. The incidence of upper GI bleeding was 5.46% in the patients undergoing adrenocortical hormone treatment, significantly higher than that in those who did not receive such treatment (2.13%). Patients who are at high risk of developing postoperative upper GI bleeding including that: age greater than 50 years; male; Glasgow Coma Score less than 10 pre and post operation; The lesion was located in brain stem and forth ventricle; Hypertensive cerebral hemorrhage; Intracerebral and intraventricular hemorrhagic brain trauma; Postoperative pneumonia, brain edema, encephalic high pressure, pyogenic infection of the central nervous system and other postoperative complications. The mortality of patients with postoperative upper GI bleeding was evidently higher than that of the patients without postoperative upper GI bleeding.

    To survey participants at various experience levels of different martial arts (MA) about upper extremity injuries sustained during training and fighting. A 21-s question survey was designed and utilised. The survey was divided into four groups (Demographics, Injury Description, Injury Mechanism, and Miscellaneous information) to gain knowledge about upper extremity injuries sustained during martial arts participation. Chi-square testing was utilised to assess for significant associations. Males comprised 81% of respondents. Involvement in multiple forms of MA was the most prevalent (38%). The hand/wrist was the most common area injured (53%), followed by the shoulder/upper arm (27%) and the forearm/elbow (19%). Joint sprains/muscle strains were the most frequent injuries reported overall (47%), followed by abrasions/bruises (26%). Dislocations of the upper extremity were reported by 47% of participants while fractures occurred in 39%. Surgeries were required for 30% of participants. Females were less likely to require surgery and more likely to have shoulder and elbow injuries. Males were more likely to have hand injuries. Participants of Karate and Tae Kwon Do were more likely to have injuries to their hands, while participants of multiple forms were more likely to sustain injuries to their shoulders/upper arms and more likely to develop chronic upper extremity symptoms. With advanced level of training the likelihood of developing chronic upper extremity symptoms increases, and multiple surgeries were required. Hand protection was associated with a lower risk of hand injuries. Martial arts can be associated with substantial upper extremity injuries that may require surgery and extended time away from participation. Injuries may result in chronic upper extremity symptoms. Hand protection is important for reducing injuries to the hand and wrist.

    Full Text Available Purpose: To explore changes in upper secondary students´ conceptions of environmental issues in how prices are determined and how they should be determined. Design: The study uses an ’alternative frameworks’ conceptual change approach to examine change in the conceptions of fifteen business and economic students. Students were asked about the prices of familiar products and asked to explain prices for eco-friendly and eco-unfriendly products. A first interview was conducted in the second year of education and the second interview a year later when students were 18 years old and in the final year of schooling. Interviews were carried out out by a researcher independent from the schools and carried out in schools. Findings: Identifies the fragmentary nature of students´ every-day thinking in relation to productivity, consumer preference and negative externalities. Results show characteristics of partial conceptions, which are considered as students´ conceptions in a process of change towards a more scientific understanding of relationships between price and environmental impacts. Practical implications: The study clarifies conceptions, which students bring to the classroom and the directions that development in understanding may take. The study should help teachers to design effective strategies to support students’ learning.

    Full Text Available Congenital bilateral ectropion of the upper eyelids is a rare, benign condition reported in ophthalmic literature. It is more frequently associated with Down’s syndrome, ichthyosis, and sporadic cases in newborns from black population. We report three cases of congenital bilateral upper eyelid ectropion associated with Down’s syndrome. Management of these patients usually requires medial and lateral canthoplasties, full-thickness pentagonal resection of the upper eyelids and placement of skin grafts. We present herein the evolution of one of these patients and we will discuss the mechanism of the eyelid ectropion and its treatment.

  15. Upper Domination: Towards a Dichotomy Through Boundary Properties

    KAUST Repository

    AbouEisha, Hassan M.

    2017-07-14

    An upper dominating set in a graph is a minimal dominating set of maximum cardinality. The problem of finding an upper dominating set is generally NP-hard. We study the complexity of this problem in finitely defined classes of graphs and conjecture that the problem admits a complexity dichotomy in this family. A helpful tool to study the complexity of an algorithmic problem is the notion of boundary classes. However, none of such classes has been identified so far for the upper dominating set problem. We discover the first boundary class for this problem and prove the dichotomy for monogenic classes.

    Upon the entry of nutrients into the small intestine, nutrient sensing mechanisms are activated to allow the body to adapt appropriately to the incoming nutrients. To date, mounting evidence points to the existence of an upper intestinal lipid-induced gut-brain neuronal axis to regulate energy homeostasis. Moreover, a recent discovery has also revealed an upper intestinal lipid-induced gut-brain-liver neuronal axis involved in the regulation of glucose homeostasis. In this mini-review, we will focus on the mechanisms underlying the activation of these respective neuronal axes by upper intestinal lipids.

    Probiotics may improve a person's health by regulating their immune function. Some trials have shown that probiotic strains can prevent respiratory infections. Even though the previous version of our review showed benefits of probiotics for acute upper respiratory tract infections (URTIs), several new studies have been published. To assess the effectiveness and safety of probiotics (any specified strain or dose), compared with placebo, in the prevention of acute URTIs in people of all ages, at risk of acute URTIs. We searched CENTRAL (2014, Issue 6), MEDLINE (1950 to July week 3, 2014), EMBASE (1974 to July 2014), Web of Science (1900 to July 2014), the Chinese Biomedical Literature Database, which includes the China Biological Medicine Database (from 1978 to July 2014), the Chinese Medicine Popular Science Literature Database (from 2000 to July 2014) and the Masters Degree Dissertation of Beijing Union Medical College Database (from 1981 to July 2014). We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for completed and ongoing trials on 31 July 2014. Randomised controlled trials (RCTs) comparing probiotics with placebo to prevent acute URTIs. Two review authors independently assessed the eligibility and quality of trials, and extracted data using the standard methodological procedures expected by The Cochrane Collaboration. We included 13 RCTs, although we could only extract data to meta-analyse 12 trials, which involved 3720 participants including children, adults (aged around 40 years) and older people. We found that probiotics were better than placebo when measuring the number of participants experiencing episodes of acute URTI (at least one episode: odds ratio (OR) 0.53; 95% confidence interval (CI) 0.37 to 0.76, P value school absence (OR 0.10; 95% CI 0.02 to 0.47, very low quality evidence). Probiotics and placebo were similar when measuring the rate ratio of episodes of acute

    This the report for the 5 year activities for the ACS Summer Schools in Nuclear and Radiochemistry. The American Chemical Society's Summer Schools in Nuclear and Radiochemistry were held at Brookhaven National Laboratory (Upton, NY) and San Jose State University (San Jose, CA) during the award period February 1, 2002 to January 31, 2007. The Summer Schools are intensive, six-week program involving both a lecture component covering fundamental principles of nuclear chemistry and radiochemistry and a laboratory component allowing hands-on experience for the students to test many of the basic principles they learn about in lecture. Each site hosted 12 undergraduate students annually, and students received coursework credits towards their undergraduate degrees. Up to 7 student credit hours were earned at San Jose State University, and Brookhaven students received up to 6 college credits through BNL's management partner, SUNY Stony Brook. Funding from the award period covered travel, housing, educational expenses, and student stipends, for the 24 undergraduate participants. Furthermore, funding was also used to cover expenses for lecturers and staff to run the programs at the two facilities. The students were provided with nuclear and radiochemistry training equivalent to a three-hour upper-level undergraduate course along with a two-hour hands-on laboratory experience within the six-week summer period. Lectures were held 5 days per week. Students completed an extensive laboratory sequence, as well as radiation safety training at the start of the Summer Schools. The summer school curriculum was enhanced with a Guest Lecture series, as well as through several one-day symposia and organized field trips to nuclear-related research and applied science laboratories. This enrichment afforded an opportunity for students to see the broader impacts of nuclear science in today's world, and to experience some of the future challenges through formal and informal discussions with

    Upper respiratory tract infection is a nonspecific term used to describe an acute infection involving the nose, paranasal sinuses, pharynx and larynx. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media, an inflammatory process within the middle ear. Environmental, epidemiologic and familial risk factors for otitis media (such as sex, socioeconomic and educational factors, smoke exposure, allergy or duration of breastfeeding) have been previously reported, but actually no data about their diffusion among Sicilian children with upper respiratory tract infections are available. To investigate the main risk factors for otitis media and their prevalence in Sicilian children with and without upper respiratory tract infections. A case-control study of 204 children with upper respiratory tract infections who developed otitis media during a 3 weeks monitoring period and 204 age and sex-matched healthy controls. Seventeen epidemiologically relevant features were inventoried by means of standardized questionnaires and skin tests were performed. Univariate analysis and multivariate logistic regression analysis were used to examine the association between risk factors and occurrence of otitis media. Otitis media resulted strongly associated to large families, low parental educational attainment, schooling within the third years of life (potitis media in the presence of asthma, cough, laryngopharyngeal reflux disease, snoring and apnea (potitis media in children exposed to smoke respectively of 166% and 277% (potitis media are common childhood diseases strongly associated with low parental educational attainment (p=0.0001), exposure to smoke (p=0.0001), indoor exposure to mold (p=0.0001), laryngopharyngeal reflux disease (p=0.0002) and the lack of breast-feeding (p=0.0014); an increased risk of otitis media recurrences was observed in the presence of allergy, persistent cough and runny nose (p=0

    This paper presents the modelling and control of a two degree of freedom upper extremity exoskeleton. The Euler-Lagrange formulation was used in deriving the dynamic modelling of both the human upper limb as well as the exoskeleton that consists of the upper arm and the forearm. The human model is based on anthropometrical measurements of the upper limb. The proportional-derivative (PD) computed torque control (CTC) architecture is employed in this study to investigate its efficacy performing joint-space control objectives specifically in rehabilitating the elbow and shoulder joints along the sagittal plane. An active force control (AFC) algorithm is also incorporated into the PD-CTC to investigate the effectiveness of this hybrid system in compensating disturbances. It was found that the AFC- PD-CTC performs well against the disturbances introduced into the system whilst achieving acceptable trajectory tracking as compared to the conventional PD-CTC control architecture.

  14. Reflections on the present and future of upper limb prostheses.

    Despite progress in research and media attention on active upper limb prostheses, presently the most common commercial upper limb prosthetic devices are not fundamentally different from solutions offered almost one century ago. Limited information transfer for both control and sensory-motor integration and challenges in socket technology have been major obstacles. By analysing the present state-of-the-art and academic achievements, we provide our opinion on the future of upper limb prostheses. We believe that surgical procedures for muscle reinnervation and osseointegration will become increasingly clinically relevant; muscle electrical signals will remain the main clinical means for prosthetic control; and chronic electrode implants, first in muscles (control), then in nerves (sensory feedback), will become viable clinical solutions. After decades of suspended clinically relevant progress, it is foreseeable that a new generation of upper limb prostheses will enter the market in the near future based on such advances, thereby offering substantial clinical benefit for patients.

  15. Visceral pain originating from the upper urinary tract

    Pain originating from the upper urinary tract is a common problem and stone colic is one of the most intense pain conditions that can be experienced in the clinic. The pain is difficult to alleviate and often leads to medical attention. In humans, pain mechanisms of the upper urinary tract pain...... are still poorly understood, which often leads to a trial and error approach in clinical pain management. Pain from the upper urinary tract seems to have all the characteristics of pure visceral pain, including referred pain with or without hyperalgesia/trophic changes in somatic tissues and viscero......-visceral hyperalgesia. However, further studies are needed to better understand these visceral pain mechanisms with regard to optimising pain management. This review gives an introduction to visceral pain in general and upper urinary tract pain in particular, with special reference to pain pathways and pharmacological...

  17. Diagnosis and management of upper gastrointestinal bleeding in children.

    Upper gastrointestinal bleeding is an uncommon but potentially serious, life-threatening condition in children. Rapid assessment, stabilization, and resuscitation should precede all diagnostic modalities in unstable children. The diagnostic approach includes history, examination, laboratory evaluation, endoscopic procedures, and imaging studies. The clinician needs to determine carefully whether any blood or possible blood reported by a child or adult represents true upper gastrointestinal bleeding because most children with true upper gastrointestinal bleeding require admission to a pediatric intensive care unit. After the diagnosis is established, the physician should start a proton pump inhibitor or histamine 2 receptor antagonist in children with upper gastrointestinal bleeding. Consideration should also be given to the initiation of vasoactive drugs in all children in whom variceal bleeding is suspected. An endoscopy should be performed once the child is hemodynamically stable. © Copyright 2015 by the American Board of Family Medicine.

  18. Acute upper gastrointestinal bleeding (UGIB) - initial evaluation and management.

    Acute upper gastrointestinal bleeding (UGIB) is the most common reason that the 'on-call' gastroenterologist is consulted. Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.

    Background: Sustainable development (SD) is a complex idea, based on environmental, economic and social dimensions. In line with SD, education for sustainable development (ESD) is an approach to teaching that combines cognitive and affective domains and aims to build empowerment abilities. Purpose: The purpose of this article is to investigate effects of the implementation of ESD in Sweden, in terms of developing students' sustainability consciousness (SC). Two groups of students were included: one was from schools with a profile of ESD and the other one was from comparable schools without explicit ESD-profile. Sample: A total of 638 students from upper secondary schools (grade 12) in science-related or social science-related programs participated in the study. Design and methods: A procedure was created for the selection of schools considered to be the most active in using an ESD approach as well as comparable schools with no explicit ESD approach. During spring 2013, the students responded to a questionnaire based on sustainability knowingness, attitudes and behaviors within the environmental, economic and social dimensions of SD that together constitute the concept of SC. Data were analyzed using SPSS software. Results: The results indicate that there are significant differences in SC between students from schools that teach with an ESD approach compared to students from regular schools. Furthermore, a significant difference between the two groups of students was found in the underlying economic dimension of SC. No significant differences were found in the environmental and social dimensions of SC. Conclusions: Although the results show that ESD-profiled schools have effect on students' SC, the effects are relatively small. Therefore, the effects and nature of the implementation of ESD are discussed.
