    Full Text Available Islamic education in schools had not completely assessed the development of students’ character and personality. Therefore, additional religious education through non-formal education and religious practices were needed in Islamic Pre-Schools. It provided a forum to foster, develop, cultivate, and transform the religious value of the students to improve their personality. The purpose of this research was to examine social phenomenon that occur naturally through the facts related to management activities of students. Qualitative research was used in this study where the data taken from head of Islamic pre-school and the school deputy, teacher, staffs, mosque administrators of Baitul Haadi, administrator of the school, staffs of Ministry of Religious Affairs as well as Islamic pre-school inspectors, parents, community leaders, and administrators of professional organizations. The finding showed that students’ management applied in Islamic pre-school through the management functions is able to provide the successful of student’s education and learning implementation. It was also found that student management applied in Islamic pre-school is planning activities of students’ admission process through the administration regularly with various regulations related to the success of education. Thus, it is expected that the government will provide the guidance and implement constant supervision in accordance with applicable regulations.

    Full Text Available Quality design and appropriate space organization in preschool settings can support preschool children's educational activities. Although the relationship between the well-being and development of children and physical settings has been emphasized by many early childhood researchers, there is still a need for theoretical design guidelines that are geared towards the improvement of this issue. This research focuses on High/Scope education and aims to shape a theoretical guideline that raises teachers' awareness about the potential of learning spaces and guides them to improve the quality of the physical spaces. To create a theoretical framework, reliable sources are investigated in the light of High/Scope education and the requirements of pre-school children educational spaces. Physical space characteristics, the preschool child's requirements and High/Scope methodology identified design inputs, design considerations and recommendations that shape the final guideline for spatial arrangement in a High/Scope setting are integrated. Discussions and suggestions in this research benefit both designers and High/ Scope teaching staff. Results help High/Scope teaching staff increase the quality of a space in an educational setting without having an architectural background. The theoretical framework of the research allows designers to consider key features and users' possible activities in High/ Scope settings and shape their designs accordingly.

    This study investigated if the quality of pre-school children's pretend play predicted their semantic organization and narrative re-telling ability when they were in early primary school. It was hypothesized that the elaborateness of a child's play and the child's use of symbols in play were predictors of their semantic organization and narrative re-tell scores of the School Age Oral Language Assessment. Forty-eight children were assessed using the Child-Initiated Pretend Play Assessment when they were aged 4-5 years. Three-to-five years after this assessment their semantic organization and narrative re-telling skills were assessed. Results indicate that the elaborateness of a child's play and their ability to use symbols was predictive of semantic organization skills. Use of symbols in play was the strongest play predictor of narrative re-telling skills. The quality of a pre-school child's ability to elaborate complex sequences in pretend play and use symbols predicted up to 20% of a child's semantic organization and narrative re-telling skills up to 5 years later. The study provides evidence that the quality of pretend play in 4-5 year olds is important for semantic organization and narrative re-telling abilities in the school-aged child.

    To test the hypothesis that maternal psychological profiles relate to children's quality of diet. Cross-sectional study. Mothers provided information on their health-related psychological factors and aspects of their child's mealtime environment. Children's diet quality was assessed using an FFQ from which weekly intakes of foods and a diet Z-score were calculated. A high score described children with a better quality diet. Cluster analysis was performed to assess grouping of mothers based on psychological factors. Mealtime characteristics, describing how often children ate while sitting at a table or in front of the television, their frequency of takeaway food consumption, maternal covert control and food security, and children's quality of diet were examined, according to mothers' cluster membership. Mother-child pairs (n 324) in the Southampton Initiative for Health. Children were aged 2-5 years. Hampshire, UK. Two main clusters were identified. Mothers in cluster 1 had significantly higher scores for all psychological factors than mothers in cluster 2 (all P diets (β = -0.61, 95% CI -0.82, -0.40, P ≤ 0.001). This association was attenuated, but remained significant after controlling for confounding factors that included maternal education and home/mealtime characteristics (P = 0.006). The study suggests that mothers should be offered psychological support as part of interventions to improve children's quality of diet.

    2012-01-01

    The article argues that Early Childhood Education & Care (ECEC) is being redesigned based on quality reform discourse with references to global knowledge economy across Nordic countries and the EU. This takes place in policy processes that extend from transnational agents like the OECD and EU...... to national governments, local municipalities and ECEC institutions. Drawing on theoretical insights from Foucauldian genealogy, Laclau and others, the article explores how these policy processes reconfigure what counts as quality in ECEC in a Danish context. It is substantiated how the Danish government...... promotes governance structures among municipalities and professionals that pull ECEC into comprehensive educational strategies. This process draws on policy advice from the OECD and EU. Quality reform thus changes in fundamental ways the organisation and content in ECEC. In discourse, learning displaces...

    Full Text Available The paper provides the framework supporting the training of educative agents to influence upon sexual education of boys and girls in pre-school age as a way to attain high quality standard in the education. These rationale starts from the assumption that it is possible to favor the training process of educative agents on the topic by means of integrating actions with a gender centered approach. The proposal is the result of a thorough study based on the socio-historical cultural approach resulting from the doctoral dissertation already presented by the first authoress. At the same time, these results contribute to the research project “Training the family for the intellectual stimulus of pre-school children. Additionally it offers the stages of sexual education at pre-school age.

  13. DNA damage in buccal mucosa cells of pre-school children exposed to high levels of urban air pollutants.

    Elisabetta Ceretti

    Full Text Available Air pollution has been recognized as a human carcinogen. Children living in urban areas are a high-risk group, because genetic damage occurring early in life is considered able to increase the risk of carcinogenesis in adulthood. This study aimed to investigate micronuclei (MN frequency, as a biomarker of DNA damage, in exfoliated buccal cells of pre-school children living in a town with high levels of air pollution. A sample of healthy 3-6-year-old children living in Brescia, Northern Italy, was investigated. A sample of the children's buccal mucosa cells was collected during the winter months in 2012 and 2013. DNA damage was investigated using the MN test. Children's exposure to urban air pollution was evaluated by means of a questionnaire filled in by their parents that included items on various possible sources of indoor and outdoor pollution, and the concentration of fine particulate matter (PM10, PM2.5 and NO2 in the 1-3 weeks preceding biological sample collection. 181 children (mean age ± SD: 4.3 ± 0.9 years were investigated. The mean ± SD MN frequency was 0.29 ± 0.13%. A weak, though statistically significant, association of MN with concentration of air pollutants (PM10, PM2.5 and NO2 was found, whereas no association was apparent between MN frequency and the indoor and outdoor exposure variables investigated via the questionnaire. This study showed a high MN frequency in children living in a town with heavy air pollution in winter, higher than usually found among children living in areas with low or medium-high levels of air pollution.

    Full Text Available In their work authors consider the significance of the organization of physical activities for the development of abilities of pre-school and school children. Led by theoretical basis that physical development of children represents the basis of their whole development, and that “fine motor skills” are determined by the development of its large motorics, the authors point to the significance of the content and structure of physical education programme in preschool institutions and younger age school classes. It is evident that the effects of cultivating of children development during preschool period can be seen in younger primary school classes. The goal of this research was to determine if and how much the different organization of preparatory part of physical education lesson for younger school children, determines the differences in the development of their motor abilities. By the use of experimental method, the effects of prolonged preparatory part of a lesson in younger school classes. This part was realized through complex of exercises which were supposed to have influence on transformation of motor abilities in relation to the structure with standard duration of certain parts of a lesson. It is determined that certain increase in body movement of students during physical activity can significantly contribute to better development of motor abilities. These abilities determine correct physical development and strengthening of health, which determines general aim of physical education.

    2017-02-01

    Full Text Available Background Pre-school and primary school teachers are directly involved in the education of children. In addition to teachers’ competences, the quality of their work is significantly influenced by their psychological well-being. It is therefore important to focus on their well-being as well as on personality traits they have. The main objective of this study was to examine the relationship between life satisfaction, happiness, optimism and personality traits of pre-school and primary school teachers in Croatia. Participants and procedure The study was conducted on a sample of 103 pre-school teachers and 117 primary school teachers who completed self-evaluated scales on personality traits, life satisfaction, happiness and optimism. Results The results demonstrated high levels of all personality traits in both samples. High levels of life satisfaction were positively associated with happiness and optimism. Personality traits were also positively associated with life satisfaction, happiness and optimism. There were no differences in life satisfaction, happiness, optimism or personality traits between pre-school and primary school teachers, except for openness to experience being higher in pre-school teachers. Emotional stability was a significant predictor of teachers’ well-being. Conclusions The results have significant implications for improvement of teaching practice at primary school and pre-school levels. The findings highlight the importance of teachers’ personality traits and their well-being for the quality of their work with children.

    Earlier research suggests that children's development is shaped in their early years of life. This paper examines whether differences in day-care experiences during pre-school age are important for children's cognitive and language development at the age of 15. The analysis is based on class...... performance at the end of elementary schooling. We assess the effects of attended types and qualities of day-care institutions on various child outcomes as measured by school grades in mathematics, science, English and Danish for the whole Danish population as well as outcomes from the 2006 PISA Denmark...... survey and a 2007 PISA Copenhagen survey. We use administrative registries to generate indicators such as child-staff ratios, child-pedagogues ratios, and the share of male staff and of staff with non-Danish origins. Furthermore, we use information on the average levels of educational attainments...

    The debate about how, where and by whom young children should be looked after is one which has occupied much social policy and media attention in recent years. Mothers undertake most of the care of young children. Internationally, out-of-home day-care provision ranges widely. These different levels of provision are not simply a response to different levels of demand for day-care, but reflect cultural and economic interests concerning the welfare of children, the need to promote mothers' participation in paid work, and the importance of socialising children into society's values. At a time when a decline in family values is held responsible for a range of social problems, the day-care debate has a special prominence. To quantify the effects of out-of-home day-care for preschool children on educational, health and welfare outcomes for children and their families. Randomised controlled trials of day-care for pre-school children were identified using electronic databases, hand searches of relevant literature, and contact with authors. Studies were included in the review if the intervention involved the provision of non-parental day care for children under 5 years of age, and the evaluation design was that of a randomised or quasi-randomised controlled trial. A total of eight trials were identified after examining 920 abstracts and 19 books. The trials were assessed for methodological quality. Day-care increases children's IQ, and has beneficial effects on behavioural development and school achievement. Long-term follow up demonstrates increased employment, lower teenage pregnancy rates, higher socio-economic status and decreased criminal behaviour. There are positive effects on mothers' education, employment and interaction with children. Effects on fathers have not been examined. Few studies look at a range of outcomes spanning the health, education and welfare domains. Most of the trials combined non-parental day-care with some element of parent training or education

    The (pre)school environment is an important setting to improve children's health. Especially, the (pre)school playground provides a major opportunity to intervene. This review presents an overview of the existing evidence on the value of both school and preschool playgrounds on children's health in terms of physical activity, cognitive and social outcomes. In addition, we aimed to identify which playground characteristics are the strongest correlates of beneficial effects and for which subgroups of children effects are most distinct. In total, 13 experimental and 17 observational studies have been summarized of which 10 (77%) and 16 (94%) demonstrated moderate to high methodological quality, respectively. Nearly all experimental studies (n = 11) evaluated intervention effects on time spent in different levels of physical activity during recess. Research on the effects of (pre)school playgrounds on cognitive and social outcomes is scarce (n = 2). The experimental studies generated moderate evidence for an effect of the provision of play equipment, inconclusive evidence for an effect of the use of playground markings, allocating play space and for multi-component interventions, and no evidence for an effect of decreasing playground density, the promotion of physical activity by staff and increasing recess duration on children's health. In line with this, observational studies showed positive associations between play equipment and children's physical activity level. In contrast to experimental studies, significant associations were also found between children's physical activity and a decreased playground density and increased recess duration. To confirm the findings of this review, researchers are advised to conduct more experimental studies with a randomized controlled design and to incorporate the assessment of implementation strategies and process evaluations to reveal which intervention strategies and playground characteristics are most effective.

    The aim of this study was to evaluate the levels of knowledge of pre-school teachers working in the province center of Isparta related with basic first-aid practices and some factors which affected these levels of knowledge. In this cross-sectional, analytic study, 110 pre-school teachers working in the province center of Isparta constituted the population. A questionnaire questioning sociodemographic properties and the level of knowledge related with first-aid practices was applied under supervision. The level of knowledge was evaluated on a 20-point scale. In the analyses, Kruskal-Wallis and Mann-Whitney U tests and Spearman's rank correlation were used. The study was approved by the Ethical Committee for Clinical Studies of Süleyman Demirel University School of Medicine (registration number: 105). The mean score of first-aid knowledge of the pre-school teachers was found to be 11.9±2.9. The least known issues included washing the wound by soap and water after a dog bite, information related with the necessity of immobilization of a child who has fallen from a high level and the phone number of National Poison Information Center (16.4%, 20.9% and 22.7%, respectively). The scores of the subjects whose knowledge of first-aid was evaluated to be well were higher compared to the subjects whose knowledge of first-aid was evaluated to be moderate (p=0.009) and poor (p=0.001). It was found that first-aid scores did not show significant difference in terms of age, working period, having received first-aid training and having faced with a condition requiring first-aid previously (p>0.05, for all comparisons). It was found that pre-school teachers had insufficient first-aid knowledge. Since the first-aid knowledge scores of the subjects who reported that they received first-aid training before did not show significant difference, it was thought that the quality of training was as important as receiving training.

  6. INCLUSIVE CULTURE IN PRE-SCHOOL INSTITUTIONS

    2011-04-01

    Full Text Available Inclusive education is a rational concept that refers to the overall and long-term transformation of institutional systems in society, especially in education. Along with the transformation, a number of important and unresolved issues still appear in both theory and practice, as the duty of pre-school institutions and schools is to educate every student in the mainstream education system. One of the most important aspects of inclusion is the inclusive culture. Regardless of the good inclusive policy and practice, one cannot talk about successful inclusion without a properly developed inclusive institutional culture.This paper is a contribution to the research considering the development of inclusive culture in three preschool institutions. It is based on the thinking and attitudes of the pre­school staff toward the necessity of developing and nurturing an inclusive culture. Successful inclusion of pupils with special needs in the mainstream school system cannot be conceived without an inclusive culture.

    2002-01-01

    Full Text Available Child is introduced with the contents of culture at first through numerous influences culture has on family life, especially on defining parenting roles. Patriarchal culture, still strong in Yugoslavia, is full of norms that clearly define roles of elders and men, and excellently demarcates differences between father's and mother's role in bringing up their children, defined by the level of responsibility attached to parents in upbringing and educating a child. Research conducted in Novi Sad, Yugoslavia in January 2002, with the primary aim of diagnosing differences in frequency and quality of parent-pre-school children play concerning many relevant correlates, most important of which is the sex of the parent. Data show high distinctive quality difference in types and approaches to play in regard of the parent in question. Differences show that patriarchal culture's influence is still very strong. The results show that mothers are burdened with the higher level of responsibility, inevitably leading to higher parenting stress. The level of parenting stress can then influence the quality of meeting the requests put to parents, as well as raising level of general anxiety in all the activities concerning the child, therefore the play itself as well.

    2006-09-01

    The purpose of this study was to detect any underlying hearing loss among the healthy pre-school children with speech delay. 76 children, aged from 1 to 5 years, underwent a thorough audiological examination consisting of tympanometry, free field testing, otoacoustic emission recordings and auditory brainstem responses (ABRs). If hearing was normal, then they were evaluated by a child neurologist-psychiatrist. According to our findings, the children were classified into 3 groups; those with normal hearing levels (group I, 52 children, 68.4%), sensorineural hearing loss (group II, 22 children, 28.9%) and conductive hearing loss (group III, 2 children, 2.6%). In group I, speech delay was attributed to pervasive developmental disorder (PDD), which represents high-functioning autistic children (37 cases). Other causes were specific language impairment (SLI)-expressive (3 cases), bilingualism (2 cases), and unknown etiology (10 cases). More than half (59%) of the children diagnosed with PDD evidenced significant language impairment limited to more than two words. Children with SLI-expressive and bilingualism used a maximum of two words. In group II, 13 children suffered from profound hearing loss in both ears, 3 from severe, 3 had profound hearing loss in one ear and severe in the other, 2 from moderate, and 1 had moderate in one ear and severe in the other. No child had mild sensorineural hearing loss. The children with profound hearing loss in at least one ear had total language impairment using no word at all (10 cases), or a maximum of two words (6 cases). When hearing loss was moderate to severe, then the speech vocabulary was confined to several words (more than two words-6 cases). Only two children suffering from conductive hearing loss both presented with complete lack of speech. A great number of healthy pre-school children with speech delay were found to have normal hearing. In this case, the otolaryngologist should be aware of the possible underlying clinical

    Several studies in developing countries have found that children who experience growth faltering in the first years of life show lower cognitive abilities than their peers. In this study, we use the Young Lives longitudinal dataset in Peru to analyze if attending pre-school affects cognitive abilities at age five years, and if there is an interaction with HAZ at age one year. Using instrumental variables we found, for receptive vocabulary, a positive effect of attending Jardines (formal) pre-schools; the effect of attending PRONOEI (community-based) pre-schools was not significant. More years attending Jardines was more beneficial for children who were better nourished. We suggest working to improve the quality of PRONOEI s, and with teachers on targeting children of lower nutritional status.

    The occurrence of burnout syndrome (BS) has been recognized in many professions (pilots, firefighters, police officers, doctors…) that during their work are subjected to high levels of stress. For educators in preschool institutions stress level is very high thus creating the possibility of developing BS. For this research is selected preschool institution - kindergarten "Radost" (Joy) in Split, in which by use of questionnaires (modified scale by Freudenberger and modified scales by Girdin, Everly and Dusek) during 2014 among educators (100 respondents) is conducted a survey regarding the frequency of burnout syndrome. According to questionnaires by Girdin, Everly and Dusek there is no statistically significant difference between the number of educators who feel good and those that are under significant stress (χ2=1.04; p=0.307). According to questionnaire by Freudenberg educators are classified into 3 categories and distribution of educators by the groups is almost uniform (χ2=2.76; p=0.250), which means that one third of a teacher is in good condition, a third is in the risk area for burn-out syndrome, while one third are candidates for development of this syndrome. Comparing a teacher in good condition compared to other (at risk and those who are candidates for the burn-out syndrome) is up to 1.5 times higher in those who are at risk and the candidates for development of this syndrome than in others (χ2=4.5; p=0.033). The occurrence of burnout syndrome is very high for the group of educators (half of the educators!) in pre-school institutions which should be taken into account by the institutions management. For this purpose, it is necessary to organize regular medical check-ups with particular reference to burnout syndrome with signs of the syndrome to prevent its further development.

    Full Text Available This study investigated the effect of attending pre-school on mucosal immunity. Children 3.5 to 5 years of age who attended pre-school were observed for a 10 month period. Demographic information was collected on previous childcare experiences, the home environment and clinical information relating to the child and the family. A daily illness log was kept for each child. A multivariate longitudinal analysis of the relation between immunoglobulins in saliva and age, gender, childcare experience, pre-school exposure, number of siblings, environmental tobacco smoke (ETS, atopy and hospitalisation was conducted. There was a positive association of higher IgA levels with the winter season and with children being older than 4 years (<.001, having attended childcare prior to commencing pre-school (<.05, and having been exposed to ETS at home (<.05. Lower IgA levels were associated with being atopic (<.05. Higher IgG levels were associated with exposure to ETS (<.001, while lower levels were associated to having atopy. Higher IgM levels were associated with previous childcare experience (<.01 whilst having been hospitalised was associated with having low salivary IgM levels (<.01. Lagged analyses demonstrated that immunological parameters were affected by the number of respiratory infections in the preceding 2 months.

    The debate about how, where and by whom young children should be looked after is one which has occupied much social policy and media attention in recent years. Mothers undertake most of the care of young children. Internationally, out-of-home day-care provision ranges widely. These different levels of provision are not simply a response to different levels of demand for day-care, but reflect cultural and economic interests concerning the welfare of children, the need to promote mothers' participation in paid work, and the importance of socialising children into society's values. At a time when a decline in family values is held responsible for a range of social problems, the day-care debate has a special prominence. To quantify the effects of out-of-home day-care for preschool children on educational, health and welfare outcomes for children and their families. Randomised controlled trials of day-care for pre-school children were identified using electronic databases, hand searches of relevant literature, and contact with authors. Studies were included in the review if the intervention involved the provision of non-parental day care for children under 5 years of age, and the evaluation design was that of a randomised or quasi-randomised controlled trial. A total of eight trials were identified after examining 920 abstracts and 19 books. The trials were assessed for methodological quality. Day-care increases children's IQ, and has beneficial effects on behavioural development and school achievement. Long-term follow up demonstrates increased employment, lower teenage pregnancy rates, higher socio-economic status and decreased criminal behaviour. There are positive effects on mothers' education, employment and interaction with children. Effects on fathers have not been examined. Few studies look at a range of outcomes spanning the health, education and welfare domains. Most of the trials combined non-parental day-care with some element of parent training or education

    Poor health and health inequalities persist despite increasing investment in health improvement programmes across high-income countries. Evidence suggests that to reduce health inequalities, a range of activities targeted at different levels within society and throughout the life course should be employed. There is a particular focus on addressing inequalities in early years as this may influence the experience of health in adulthood. To address the wider determinants of health at a community level, a key intervention which can be considered is supporting patients to access wider community resources. This can include processes such as signposting, referral and facilitation. There is a lack of evidence synthesis in relation to the most effective methods for linking individuals from health services to other services within communities, especially when considering interventions aimed at families with young children. The aim of this study is to understand the way health services can best help parents, carers and families with pre-school children to engage with local services, groups and agencies to address their wider health and social needs. The review may inform future guidance to support families to address wider determinants of health. The study is a systematic review, and papers will be identified from the following electronic databases: Web of Science, Embase, MEDLINE and CINAHL. A grey literature search will be conducted using an internet search engine and specific grey literature databases (TRiP, EThOS and Open Grey). Reference lists/bibliographies of selected papers will be searched. Quality will be assessed using the Effective Public Health Practice Project Quality Assessment Tool for quantitative studies and the CASP tool for qualitative studies. Data will be synthesised in a narrative form and weighted by study quality. It is important to understand how health services can facilitate access to wider services for their patients to address the wider

    The dental health of preschool children has extensive implications on the oral heath of the individual as he grows into an adult. Parents/guardians of preschool children play a central role in enforcing proper oral hygiene and preventive regime in these children. This study was conducted with the aim of describing the views of parents/guardians about the dental health of pre-school children. Response was obtained on a 21 point questionnaire from randomly visiting parents of the outpatient section of Rajah Muthiah dental college and Hospital, Annamalainagar, India. The findings of the present study point towards poor awareness among the parents/guardians of preschool children, pertaining to their childs' oral health and this could directly translate to poor oral health among the children in this area.

    Hartmann-Shack images taken from an archived collection of SureSight refractive measurements of pre-school children in Oxford County, Ontario, Canada were retrieved and re-analyzed. Higher-order aberrations were calculated over the age range of 3 to 6 years. These higher-order aberrations were compared with respect to magnitudes of ametropia. Subjects were classified as emmetropic (range -0.5 to + 0.5D), low hyperopic (+ 0.5 to +2D) and high hyperopic (+2D or more) based upon the resulting spherical equivalent. Higher-order aberrations were found to increase with higher levels of hyperopia (p < 0.01). The strongest effect was for children showing more than +2.00D of hyperopia. The correlation coefficients were small in all of the higher-order aberrations; however, they were significant (p < 0.01). These analyses indicate a weak association between refractive error and higher-order aberrations in pre-school children.

    Little is known to date about the relationship between poor motor abilities and overweight or obese pre-school children. Thus, this study examined the association between motor abilities and weight status in 1,228 kindergarten children (45.8% female). Anthropometric data were assessed; age 4.7 + or - 1.0 years; height 108.6 + or - 8.0 cm; weight 19.1 + or - 3.6 kg; BMI 16.1 + or - 1.5 kg/m(2). The modified Karlsruher Motor Ability Screening Test was carried out to determine the motor abilities of speed strength, muscular endurance, coordination, flexibility, and speed. Based on the German BMI reference values, 3.5% of the children were obese, 9.6% overweight, 83.4% normal weight, and 3.5% underweight. During various test tasks, below-average motor abilities were discovered in 44.0-47.3%. In all age groups, overweight and obese children did not differ from their normal and underweight counterparts; except for underweight children which fared worse in flexibility. In contrast to former studies with first graders, overweight or obese pre-school children did not possess worse motor abilities than normal weight children. However, the high number of overweight children and motor deficits suggests that preventive measures should start at this early age. Copyright 2009 S. Karger AG, Basel.

    Full Text Available In present life conditions, especially in urban environment, children have very poor conditions for physical activities, or for movement in general. According to the new researches, working conditions and quality of work in nurseries and schools, especially if they are related to physical exercises, have certain influences on overall development of pre-school and school children. Childhood is ideal time for correction of numerous postural disturbances and deformities, whether they are congenital or acquired by injury, wrong body posture, or by poor nutrition. Playing is a power fultool for directing correct development of children, so very of ten it has to be adapted to age, capabilities, interests and needs of children.

Instructor, Department of Psychology, Faculty of Medicine, Lorestan University of Medical Sciences, Khorramabad, Iran Abstract Background: Childhood period it one of the most important stages of life in which individuals personality is formed. The majority of behavioral problems are due to attention deficit to the sensitive periods of childhood. This attention deficit leads to lack of agreement with environment and causes behavioural problems in children. Behavioural problem is attributed to a persons behaviour that his IQ isn lowered, but his or her mental and behavioural equilibrium is deviated from social norm and has severity, repetition and continuance in numerous times and places, so that his educational performance and behaviour will be frustrated and his efficiency is reduced. Such children are always rejected by others and in school there are a lot of grievances against them. Therefore, to pay attention children common behavioural problems is one of the most important topics and it prompt detection makes its treatment possible. So this study designed to determine prevalence of behavioural problems of Khorramabad pre-school children. Materials and methods: This descriptive-cross sectional study was carried out on 600 rural and urban pre-school children selected using random one stage sampling method. Data gathering tool was a two-part questionnaire including demographic and behavioural disorders signs obtained from DSM IV. Reability and validity of the questionnaire was confirmed by the university teaching members and retest method with a correlation coefficient 98%. Data were analyzed using SPSS software (ver 11 and Ch-square test.

    The relative risks and benefits of children attending kindergarten or pre-school remain uncertain and controversial. We used data from the Bavarian Pre-School Morbidity Survey (BPMS) to look at the prevalence of developmental impairments in pre-school children entering primary school and to assess if these were correlated with the duration of kindergarten attendance. We collected data from all school beginners in the district of Dingolfing, Bavaria from 2004 to 2007 (n = 4,005) and utilised a retrospective cross-sectional study design to review the information. The children were assessed for motor, cognitive, language and psychosocial impairments using a standardized medical assessment. Point prevalence of impairments of speech, cognition, motor functioning and psychosocial functioning were compared by chi(2)-test for the variable of time spent in kindergarten. We detected a high incidence of impairments, with boys showing higher rates than girls in all the areas assessed. Longer length of time spent in kindergarten was associated with reduced rates of motor, cognitive and psychosocial impairments. There was no clear correlation between length of kindergarten attendance and speech disorders. Kindergarten attendance may have a positive effect on a number of domains of development including motor, cognitive and psychosocial development, but no significant effect on speech impairments. Implications for public health policies are discussed.

    The behavior of 24 children, aged 3-6 years, was recorded on video-tape. Simultaneously the ECG was recorded telemetrically. These observations were made during two pre-school educational programs lasting 90 minutes each: "Didactic games" and "Elementary music and movement program". For each child a scale was developed to show the correlation of mean heart-rate and well defined motor-activity. It was evident that the mean heart-rate was higher during the music program than during the didactic program, corresponding to the higher motor-activity. But it was found that in the didactic program the variation of the heart-rate within short intervals was higher due to the more frequent occurrence of respiratory arrhythmias. It was also seen that during the music program the children showed no signs of exertion as they did towards the end of the didactic program. Respiratory arrhythmias were not seen in children who according to the Schellong-test were classified as stable in their cardiovascular system. The arrhythmias occurred mainly when the children showed signs of fatigue.

    To evaluate knowledge, attitudes, and environment of primary care providers, and to develop a conceptual framework showing their impact on self-reported pre-school vision screening (PVS) behaviors. Eligible primary care providers were individuals who filed claims with Medicaid agencies in Alabama, South Carolina, or Illinois, for at least eight well child checks for children aged 3 or 4 years during 1 year. Responses were obtained on-line from providers who enrolled in the intervention arm of a randomized trial to improve PVS. We calculated a summary score per provider per facet: (1) for behavior and knowledge, each correct answer was assigned a value of +1; and (2) for attitudes and environment, responses indicating support for PVS were assigned a value of +1, and other responses were assigned -1. Responses were available from 53 participants (43 of 49 enrolled pediatricians, 8 of 14 enrolled family physicians, one general physician, and one nurse practitioner). Recognizing that amblyopia often presents without outward signs was positively related to good PVS: [odds ratio (OR) = 3.9; p = 0.06]. Reporting that "preschool VS interrupts patient flow" posed a significant barrier (OR = 0.2; p = 0.05). Providers with high summed scores on attitudes (OR = 6.0; p = 0.03), or knowledge and attitudes (OR = 11.4; p attitudes or environment, and "good" PVS behavior (p = 0.04). PVS is influenced by positive attitudes, especially when combined with knowledge about amblyopia. Interventions to improve PVS should target multiple facets, emphasizing (1) asymptomatic children are at risk for amblyopia, (2) specific evidence-based tests have high testability and sensitivity for amblyopia in pre-school children, and (3) new tests minimize interruptions to patient flow.

    Full Text Available The research has included 96 Roma elementary-school pupils from the first grade, 7 years and 6 months old on average, and 78 pre-school children, (6 years and 1 month old on average, out of which number there were 37 Roma pupils and 41 non-Roma pupils. The cognitive functioning has been tested with a battery consisted of 5 tests, which was based on the (adapted Wechsler’s scales and the linguistic competence test. The results have shown a significant lagging of Roma children behind the control group and test norms. The Analyses of Covariance have pointed to a significant influence of the father’s educational background on the test score, but the difference between groups remained notable even when that variable was kept under control. However, the Item Analyses revealed a number of items that turned out to be evidently "unfair" toward Roma children, and their elimination contributed to the annulling of differences among groups in the Analyses of Covariance for a particular number of tests. The data has been interpreted by the authors as a proof of necessity and possibility to adapt tests for the needs of testing the educationally neglected children. The fact that the greatest differences have been noticed in the tests saturated with the factors of visual-motor coordination and memory has been justified by the authors with the Roma children’s lack of experience of manipulation with toys and possible attention deficit as a consequence of absence of stimulative environment.

  3. Foot shape and its relationship with somatic characteristics in pre-school children

    Full Text Available Introduction : The preschool period, characterised by high intensity of ontogenetic developmental changes, is considered to be the most important regarding formation of the foot. Getting to know the issue of the foot anatomy in children in this period is the main problem, which is the starting point towards proper prevention, examination, or correction of its deformities. Aim of the research: To analyse the shape of children’s feet and its relationship with chosen somatic characteristics in pre-school children. Material and methods : The study group comprised 80 five-year-old children recruited from randomly selected pre-schools in the Podkarpackie region. A CQ-ST podoscope was used as the research tool. In order to evaluate intersex differences at the average level of the tested variables, we used the Student’s t test or alternatively the Mann-Whitney U test. The relations between tested variables was assessed using Pearson’s linear correlation or Spearman’s rank correlation. Results : A low percentage of foot deformities in the children was found. In girls, statistically significant relationships were seen between Clarke’s angle in the right foot and body mass index as well as between Wejsflog index in the right foot and body weight and height. In the case of boys, Clarke’s angle and Wejsflog index in the left foot correlated with body mass index. Conclusions: We can therefore assume that most of the surveyed girls and boys had correctly longitudinally and transversely arched feet and toes positioned correctly. Excessive weight was a factor distorting the foot shape in children; it caused a deterioration of longitudinal and transverse arch of the right foot in girls, and left foot flattening occurred in boys.

  5. THE ENVIRONMENT AS A CRUCIAL LEARNING FACTOR AT PRE-SCHOOL

    Directory of Open Access Journals (Sweden)

    Snježana Močinić

    2016-01-01

    Full Text Available In this essay, the author hypothesizes that physical environment is an essential factor for developing an educational project. The environment is considered a sort of "third educator", playing a decisive role in determining the quality of learning. Classrooms, laboratory, the corridor, the structure of the building itself and the context in which the building is placed; the colours of the walls, the quality of natural and artificial light in the building, the furniture and materials for learning are variables which determine the environment where a child lives, learns, experiences, begins relationships with other people. The educator is very important in the process of a child's development. By means of direct and indirect action, he/she can create an attractive space in the building, more accessible for the processes of functional learning. The empirical research, described in the present survey, underlines the importance of pre-schools as an important place for meeting, interaction, listening and reciprocity leading toward an improvement in the relationship between the child and the school environment. In particular, this empirical research will show the diversity of the places and materials teachers made available to children.

    During a period of rapid globalisation, education has an obligation to adapt to the -needs of society. Current Lithuanian education policy for pre-school children provides that each child must be granted access to public services, working or needy families must be provided with greater support and a wider range of educational programmes that meet the needs of parents and children have to be developed. Currently in Lithuania, pre-school and pre-primary education is not mandatory, but it is...

    Full Text Available This longitudinal research started from the conclusion reached by different authors. According to them the time when a child leaves a pre-school institution to start primary school is marked by stagnation of and decrease in child’s creativity, seen as a personality potential. The aim of the research was to establish creativity levels shown by children in both pre-school institution and primary school, and then to conclude if difference between pre-school and school teachers` attitudes influence the development of a child’s creativity. Data was collected from a judgment scale given to pre-school and school teachers and arts creativity task given to children. It was concluded that the level of children’s creativity started to drop after they started primary school. Different understanding of the idea of creativity between pre-school and primary school teachers could be a possible reason leading to the phenomenon of decreasing creative expression in children starting primary school. On the basis of previous theoretical assumptions and the research results it is possible to define measures to be taken in view of teacher training, both at pre-school and primary school level. It is also important to check the validity of suggested measures in future research.

    At the moment the noise functions available in a graphics programmer's toolbox are either slow to compute or they involve grid-line artifacts making them of lower quality. In this paper we present a real-time noise computation with no grid-line artifacts or other regularity problems. In other words......, we put a new tool in the box that computes fast high-quality noise. In addition to being free of artifacts, the noise we present does not rely on tabulated data (everything is computed on the fly) and it is easy to adjust quality vs. quantity for the noise. The noise is based on point rendering (like...... spot noise), but it extends to more than two dimensions. The fact that it is based on point rendering makes art direction of the noise much easier....

    Physical activity is an important determinant of energy balance. However, its impact on overweight/obesity has proved difficult to measure in pre-school children and few studies have found significant associations. A set of simple questions was used to distinguish pre-school children with high and low physical activity, and the association of this classification with childhood overweight/obesity and performance in an established motor test was investigated. Survey, cross-sectional. Weight and height were measured in 12,556 children taking part in the obligatory school entrance health examination 2004-5 and 2005-6 in three urban and three rural Bavarian regions. Their parents were asked to answer a questionnaire with a set of questions on physical activity. The mean age of the children evaluated was 5.78 (sd 0.43) years, 6535 (52.1 %) were boys. Physically active children were less likely to be overweight (OR = 0.786, 95 % CI 0.687, 0.898) or obese (OR = 0.655, 95 % CI 0.506, 0.849) and achieved 6.7 (95 % CI 5.8, 7.7) % more jumps per 30 s than less active children in a motor test, adjusted for a number of potentially confounding variables. Classification of pre-school children as physically active or not, based on a small set of questions, revealed significant associations with overweight/obesity and a motor test. Once further validated, this classification might provide a valuable tool to assess the impact of physical activity on the risk of childhood overweight and obesity.

    The objectives of this study were: to provide restorations using the ART approach to pre-school children in Southern China in a kindergarten environment, using a high-strength glass-ionomer restorative material; to assess the acceptability of this approach and to evaluate on a longitudinal basis the restorations placed. A total of 170 ART restorations were placed in 95 children, aged 5.1 +/- 0.7 years, by seven final-year dental students using standard ART procedures and hand instruments. The restorations were evaluated every six months thereafter by two calibrated independent examiners using explorers and mouth-mirrors. 93% of the children reported that they did not feel pain during treatment and 86% were willing to receive ART restorations again. The cumulative 12- and 30-month survival rates of Class I restorations were 91% and 79%, respectively. The corresponding figures for Class V restorations were 79% and 70%, while those for Class II restorations were 75% and 51%. The failure rates of Class III and IV restorations were high with more than half of them scored as missing within the first year. The ART approach was shown to be acceptable to Chinese pre-school children for providing restorative dental care outside the traditional clinical setting. The success rates were high for Class I and V restorations in primary teeth, modest for Class II, and low for Class III and IV restorations.

    A pre-school offering a full-day-care service provides for children aged 0-5 years for more than 4 h\\/d. Researchers have called for studies that will provide an understanding of nutrition and physical activity practices in this setting. Obesity prevention in pre-schools, through the development of healthy associations with food and health-related practices, has been advocated. While guidelines for the promotion of best nutrition and health-related practice in the early years\\' setting exist in a number of jurisdictions, associated regulations have been noted to be poor, with the environment of the child-care facility mainly evaluated for safety. Much cross-sectional research outlines poor nutrition and physical activity practice in this setting. However, there are few published environmental and policy-level interventions targeting the child-care provider with, to our knowledge, no evidence of such interventions in Ireland. The aim of the present paper is to review international guidelines and recommendations relating to health promotion best practice in the pre-school setting: service and resource provision; food service and food availability; and the role and involvement of parents in pre-schools. Intervention programmes and assessment tools available to measure such practice are outlined; and insight is provided into an intervention scheme, formulated from available best practice, that was introduced into the Irish full-day-care pre-school setting.

Material and Methods: analysis and systematization of scientific and methodological literature, medical histories, anamneses, interviews and questionings. Results: it is specified that failure to timely identify and eliminate the symptoms of hip dysplasia in pre-school children leads to negative consequences, namely limited amplitude of hip joint movements; lower limp muscle weakness; valgus and varus deformations of lower limp; increasing of L-lordosis; skewness of hip bones; scoliosis; claudication. Conclusions: the modern state of the problem of hip dysplasia in pre-school children is analyzed. The cause-effect relationship is defined, their mutual transition is projected. All cause-effect relationships are in direct proportion and in constant interaction: the cause the forms effect and the effect influences the cause

    Full Text Available The adaptability of children to the school environment and their potential to succeed there is closely linked to the development of their cognitive and social skills. These are primarily linked to personal factors -physical maturity as well as mental or emotional maturity and the environment in which those children grow up. This fact is evident in children growing up in disadvantageous socio-economic conditions. In general the school readiness of children from socially-disadvantaged backgrounds is affected by the specific environment, the primary family and a number of other factors. A significant support of psychosocial development and successful adaptability at the start of the compulsory education is the preschool education, especially for children growing up in disadvantageous socio-economic conditions. The presented study focused on the effect of pre-school education on school readiness in first grade children. 24 children from socially disadvantaged environment were tested twice - for first time shortly after the beginning of their first grade and for the second time before the end of the first grade. The children were then divided into two groups - those who attended pre-school education and those who started school without any pre-school education programme. The attendance thus made the independent variable in the research design. There were three research questions - what is the impact of pre-school education on: Q1: general cognitive functioning (tested using the Intelligence Image Scale, Q2: on the ability to acquire the reading skills (tested using the Reversal test by Edfeldt and Q3 on the social maturity of the children (tested using the Vineland scale of adaptive behaviour The results of the study suggest that pre-school education has significant effect on social skills and this effect increases during the first year. The reading skills were better in children who attended the pre-school education however this impact decreases

    2013-12-01

    Full Text Available In the article the author describes specfic mechanisms of neoliberalization at work in pre-school education in Poland. The argument is based on an ethnographic analysis of a theatre performance which crowned one of Wrocław’s educational projects called “Enterprising Pre-school Student”. It demonstrates the workings of neoliberal ideology, which—based on the niche marketing strategy—targets specific needs of particular consumer groups. Addressing children with a specialised marketing message, the strategy uses fairy tales as a tool and cover for instilling desired behaviour patterns in them.

    Full Text Available Objective: The aim of this article is to determine the level of noise in nurseries and pre-schools and also to compare measured levels with standard levels and evaluate the teachers’ level of annoyance. Materials and Methods: The level of noise was measured in three different schools. A total of 162 students, whose ages were between 3 and 6 years, and 12 teachers were included the study. Every age groups’ level of noise was measured during sleeping, gaming, and eating activity. In addition, teachers’ annoyance was assessed in different age groups. Results: The 4- to 6-year-old groups were found to have higher level of sounds than 3-year-old group. Eating period was found to be the highest level of sound whereas sleeping was found the lowest. Furthermore, teachers’ annoyance was found higher as the age decreased. Conclusion: Nurseries and pre-schools have noisy environment both for the students and the teachers. High level of noise, which has bad effects on health, is a public health problem. Both the students’ families and teachers must be aware of this annoying situation.

    Full Text Available There has an increasing number of published trials on psychosocial intervention programmes for pre-school children with autism spectrum disorder (ASD. To achieve better quality of unbiased evidence for the effectiveness of ASD interventions, it is necessary to conduct a comprehensive review that covers studies with adequate quality standards, such as randomised controlled trials (RCTs, and different types of intervention In this study, we categorize interventions for ASD as behavioural, social-communication focused, and multimodal developmental based on Howlin's classification of early interventions for children with ASD. The aim of this study was to compare these three models and investigate the strengths and weaknesses of each type of intervention and to identify the approaches that contribute to a successful outcome for children with autism.We performed a systematic review and meta-analysis. We included RCTs targeting children with ASD 6 years old or younger. A random effects model was used to present the effect estimate for the outcomes. This study also performed combined meta-analyses of all the three models to investigate the overall effectiveness of the intervention programmes.32 randomized controlled studies were found to be eligible for inclusion. The synthesized data included 594 children from 14 RCTs. There was no statistically significant difference in the effects on autism general symptoms between the social-communication-focused model and the multimodal developmental model (p = 0.83.

    Full Text Available The assessment of motor behavior and general intellectual abilities were performed on a sample of 42 pre-school children (22 boys and 20 girls aged 6 (±3 months; moreover, the self-concept of those children was analysed. For the assessment of their motor behavior six movement tasks were chosen and the Mary Gutrich scale was applied for the analysis of the results. The children's intellectual abilities were assessed by the means of Raven's colored progressive matrices so as to enable the groups to homogenise, as well as to eliminate potential parasite factors when drawing conclusions. The self-concept analysis was performed using the pshychological interview during the course of which the children described their impression of their own abilities with regard to the past, present and future. The data related to the self-concept were complemented with the analysis of the children's drawings. The statistical analysis of the data gathered showed that motor behavior plays a significant role in developing one's self-concept, which is especially true of boys. Even though there is no significant statistical difference between boys and girls with respect to the quality of their motor behavior, there are significant differences between them pertaining to the vocabulary they use when describing their own selves, i.e. their self-concept, especially with respect to the present and future. Boys seem to use more extensive motor-related vocabulary when describing themselves, especially those with greater motor skills. Both boys and girls show a tendency to describe themselves as incapable in the past. When describing their present moment capabilities, girls tend to use vocabulary related to play and independence, whereas they mostly use vocabulary related to professions and sex roles when referring to the future. These findings indicate that social factors are of immense importance from a very early age, especially among girls. Moreover, the results show that

    Motor coordination deficits that characterize children with Developmental Coordination Disorder (DCD) affect their quality of participation. The aim of the current study was to identify play characteristics of young children with DCD, compared to those of children with typical development in three dimensions: activity and participation, environmental factors and children's impairments. Sixty-four children, aged four to six years, participated. Thirty were diagnosed as having DCD; the remaining 34 children were age, gender and socioeconomic level matched controls with typical development. The children were evaluated by the M-ABC. In addition, their parents completed a demographic questionnaire, the Children's Activity Scale for Parents (CHAS-P), the Children's Leisure Assessment Scale for preschoolers (CLASS-Pre), and My Child's Play Questionnaire (MCP). Children with DCD performed significantly poorer in each of the four play activity and participation domains: variety, frequency, sociability, and preference (CLASS-Pre). Furthermore, their environmental characteristics were significantly different (MCP). They displayed significantly inferior performance (impairments) in interpersonal interaction and executive functioning during play, in comparison to controls (MCP). Moreover, the children's motor and executive control as reflected in their daily function as well as their activities of daily living (ADL) performance level, contributed to the prediction of their global play participation. The results indicate that the use of both the CLASS-Pre and the MCP questionnaires enables the identification of unique play characteristics of pre-school children with DCD via parents' reports. A better insight into these characteristics may contribute to theoretical knowledge and clinical practice to improve the children's daily participation. Copyright © 2016 Elsevier B.V.

    Full Text Available Introduction: Family centres in Sweden are integrated services that reach all prospective parents and parents with children up to their sixth year, because of the co-location of the health service with the social service and the open pre-school. The personnel on the multi-professional site work together to meet the needs of the target group. The article explores a program theory focused on the open pre-schools at family centres.Method: A multi-case design is used and the sample consists of open pre-schools at six family centres. The hypothesis is based on previous research and evaluation data. It guides the data collection which is collected and analysed stepwise. Both parents and personnel are interviewed individually and in groups at each centre.Findings: The hypothesis was expanded to a program theory. The compliance of the professionals was the most significant element that explained why the open access service facilitated positive parenting. The professionals act in a compliant manner to meet the needs of the children and parents as well as in creating good conditions for social networking and learning amongst the parents. Conclusion: The compliance of the professionals in this program theory of open pre-schools at family centres can be a standard in integrated and open access services, whereas the organisation form can vary. The best way of increasing the number of integrative services is to support and encourage professionals that prefer to work in a compliant manner.

    Full Text Available This article describes, analyzes, and evaluates children’s participatory in Finnish pre-school groups. Children’s participation is viewed in the context of the Core Curriculum for Pre-school Education in Finland (2010, in which children are considered active subjects, who interact with both other people and the environment. However, in practical data, collected via survey from pre-school educators, this ideology is restricted and the educators in pre-school groups focus on children’s participation from a narrow point of view that reflects a lack of connection between the Core Curriculum goals for pre-school education and the actual participatory practices children face.

    To examine the association between skipping breakfast, daily energy, macronutrients and food intakes, and BMI in pre-school children. A cross-sectional study using information on children's food consumption and measured height and weight. Energy and macronutrient intakes of the children were derived from parent/day-care attendant's responses to 24 h recall interviews and eating behaviour questionnaires. Data obtained from a representative sample (n 2,103) of children born in Quebec (Canada) in 1998. One thousand five hundred and forty-nine children, with a mean age of 49 (sd 3.12) months. Ten per cent of children ate breakfast on fewer than 7 days per week. This behaviour was associated with a lower diet quality and concentrated energy intakes through higher protein intakes at lunch and the consumption of snacks higher in energy and carbohydrate in the afternoon and evening; yet total daily energy intakes were not significantly different from those of pre-school children who ate breakfast every day. Breakfast skippers' mean BMI increased as intake of energy, carbohydrates or servings of grain products increased; however, this was not the case for breakfast eaters. When Cole's cut-off for overweight/obesity was used, overweight/obesity in breakfast skippers was related to the dinner-time consumption of approximately 3,000 kJ (700 kcal) or more for energy intake, approximately 100 g or more of carbohydrates, or approximately 3 servings or more of grain products. Eating breakfast every day is associated with having a healthy body weight, likely due to a more even distribution of energy intake across meals throughout the day.

This study aimed to examine the exposure status of SHS and the factors associated with SHS avoidance behavior among the mothers of pre-school children. Methods A cross-sectional study was used to obtain a sample of the mothers of pre-school children (n = 1,020 in 30 registered kindergartens in eastern Taiwan. Overall, 919 (a response rate of 90% completed the questionnaires. Regression models were used to identify factors with respect to the avoidance behavior of SHS. Results The prevalence of exposure to SHS was 70% and 50% for the mothers and their children, respectively. After adjusting for other variables, mothers who were current smokers (β = -0.260, p Conclusions The high prevalence rate of exposure to SHS for mothers and their children suggests that a well-designed future intervention program should be implemented in regard to pre-school children's mothers in order to prevent these mothers and their children from SHS exposure hazards, more particularly, to strengthen the knowledge base, to enhance self-efficacy and to foster a more positive attitude toward the avoidance of SHS in the mothers.

    Full Text Available This paper presents a part of the research the goal of which was to study the notion about syntax as one of the meta-linguistic abilities that contributes to adoption of reading. Research comprised two hundred children of pre-school age, divided into two groups, balanced according to gender, intelligence and socioeconomic status. The research was conducted by an experimental method test-retest. In the initial measuring, experimental and control group were given the list comprising three kinds of experimental tasks for determining the level of development of notion about syntax, constructed by the author of the research. Experimental program consisted of tasks for stimulation of development of notion about syntax, which children practiced in the course of ten days (up to 30 minutes a day, with the help of previously trained pre-school teachers. After the ten-day training, final measuring in both groups was performed in both groups of respondents, by parallel form of tasks. The goal of the research was to determine whether it is possible to encourage the development of notion about syntax in children of pre-school age by systematic practice. The results of final measuring indicate that both in experimental and control group there have been significant improvements with respect to development of notion about syntax, and that the number of answers in which judgement was based on the semantic criterion (experience and meaning was significantly reduced. In making judgements based on consequences (content of the sentence points to something which is a good or not a good thing to do, moral or immoral there were no significant differences in the final compared to the initial measuring in both groups. Significant differences in retest were found in making judgements based on meaning. The mere experience with test material at pre-school age brings about the improvement of the notion about language, and practice contributes considerably to shifting the

    We recently developed and validated a screening questionnaire for determining which school-aged children may need further investigation to diagnose and manage asthma. In the present study we sought to extend this to pre-school aged children. Questions from the school-aged questionnaire and literature on pre-school asthma were used to inform a focus group of parents with pre-school-aged children with asthma to develop a screening questionnaire. Parents of children attending 6 randomly selected kindergartens in Trelew, Argentina (n = 639) were invited to respond to the questionnaire. A reliability test-retest was undertaken in 187 randomly selected parents who completed the same questionnaire twice within 2-5 weeks. Clinical assessment included a standardized history and physical examination, spirometry before and after a β-agonist inhaler, and chest X-ray. Asthma was diagnosed by the pulmonologist. Completed surveys were returned for 620 children, 607 of whom underwent clinical evaluation. The mean age was 4.21 years (range of 3.01-5.50) and included 82.5% white and 49.4% male children. Asthma was diagnosed in 103 (17.0%) children); 72 (69.9%) of these children did not have a previous diagnosis of asthma. The specificity, sensitivity, positive predictive value and negative predictive value of the questionnaire were 93.2%, 86.1%, 57.8% and 98.4%, respectively. We have demonstrated the utility of a screening questionnaire for identifying pre-school-aged children who may benefit from further assessment for asthma. © 2015 Asian Pacific Society of Respirology.

    Childhood is important and critical period in human life. The foundation of ego is shaped in childhood. Play therapy is one of the successful strategies to help children with inner conflicts problems. This method of psychotherapy is base on the normal learning processes of children, provides solutions to relieve feelings of stress, and expands self-expression. Group play therapy can enhance the self-awareness, self- regulation, social communication, empathy and adoptability in children. Present study investigated the effects of play therapy on relational and emotional skills of pre-school children. For this purpose, the total numbers of 372 pre-school children were randomly selected, and divided into two equal groups (case and control). In next step, the BUSSE-SR methodology was used for evaluation and comparison of self-awareness, self-regulation, social interaction, empathy, adoptability, and control groups. Pre-test were performed for both groups and case group was involved in-group play therapy. According to the results of post-test, correlation of variables between case-control groups was examined by multivariate analysis of covariance. Frequency of boys and girls in our sample were 51.3 and 48.7 percent, respectively. The mean age of children was 5.1±0.6 year.

    Dynamic assessment has been shown to have considerable theoretical and clinical significance in the assessment of socially disadvantaged and culturally and linguistically diverse children. In this study it is used to enhance assessment of pre-school children with primary language impairment. The purpose of the study was to determine whether a dynamic assessment (DA) has the potential to enhance the predictive capacity of a static measure of receptive vocabulary in pre-school children. Forty pre-school children were assessed using the static British Picture Vocabulary Scale (BPVS), a DA of word learning potential and an assessment of non-verbal cognitive ability. Thirty-seven children were followed up 6 months later and re-assessed using the BPVS. Although the predictive capacity of the static measure was found to be substantial, the DA increased this significantly especially for children with static scores below the 25th centile. The DA of children's word learning has the potential to add value to the static assessment of the child with low language skills, to predict subsequent receptive vocabulary skills and to increase the chance of correctly identifying children in need of ongoing support.

    1992-08-01

    Zerodur is a glass-ceramic composite importance in applications where temperature instabilities influence optical and mechanical performance, such as in earthbound and spaceborne telescope mirror substrates. Polished Zerodur surfaces of high quality have been required for laser gyro mirrors. Polished surface quality of substrates affects performance of high reflection coatings. Thus, the interest in improving Zerodur polished surface quality has become more general. Beyond eliminating subsurface damage, high quality surfaces are produced by reducing the amount of hydrated material redeposited on the surface during polishing. With the proper control of polishing parameters, such surfaces exhibit roughnesses of < l Angstrom rms. Zerodur polishing was studied to recommend a high surface quality polishing process which could be easily adapted to standard planetary continuous polishing machines and spindles. This summary contains information on a polishing process developed at LLNL which reproducibly provides high quality polished Zerodur surfaces at very high polishing efficiencies

    Psychiatric disorders are seen frequently in atopic diseases. The present study aims to evaluate the frequency of psychiatric disorders and the severity of psychiatric symptoms in pre-school children with cow's milk allergy. The parents of the pre-school children with cow's milk allergy were interviewed in person and asked to fill out the Early Childhood Inventory-4 form. The cow's milk allergy group included 40 children (27 male, 13 female) with mean age, 44.5±14.7 months, and the control group included 41 children (25 male, 16 female) with mean age, 47.6±15.2 months. It was established that 65% of the group with cow's milk allergy received at least one psychiatric diagnosis, while 36.6% of the control group received at least one psychiatric diagnosis, with a statistically significant difference (p=0.02). Within the psychiatric disorders, attention deficit hyperactivity disorders (odds ratio: 4.9, 95% CI: 1.472-16.856, p=0.006), oppositional defiant disorder (odds ratio: 5.6, 95% CI: 1.139-28.128, p=0.026), and attachment disorder (odds ratio: 4.8, 95% CI: 1.747-13.506, p=0.004) were found significantly higher compared with the healthy control group. When the groups were compared in terms of psychiatric symptom severity scores, calculated by using the Early Childhood Inventory-4 form, attention deficit hyperactivity disorders severity (p=0.006) and oppositional defiant disorder severity (p=0.037) were found to be higher in the cow's milk allergy group. Psychiatric disorders are frequent and severe in pre-school children with cow's milk allergy. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

Employing The Family Environment Questionnaire (Zupančič, Podlesek, & Kavčič, 2004, 2 internally replicable parenting styles were identified with maternal and paternal self-report data sets. The styles differed mainly by authoritative parenting and stimulation, and appeared structurally similar between the spouses. Parental agreement on individual style membership significantly exceeded chance levels, but was relatively low. Therefore further analyses considered maternal parenting style only. The mothers also filled in The Inventory of Child Individual Differences (Halverson et al., 2003 and the teachers (concurrently and one year later filled in The Social Competence and Behavior Evaluation scales (LaFreniere et al., 2001. Child personality type membership was based on classifications derived in a previous study. Relatively, the personality type exerted the strongest and the most consistent effects on child social behavior in pre-school. Social functioning of the resilient and the willful children was somewhat more efficient in comparison to their counterparts with the average profile, even though the latter showed the most improvement in these domains between ages 3 and 4. With the willful children only, less-than-optimal parenting had an adverse effect on the development of externalizing behavior, while the development of social adjustment was negatively affected by the children's late entry to pre-school.

    Full Text Available Abstract Background Any intervention to reduce the inappropriate use of antibiotics for infections in children has the potential to reduce the selective pressure on antimicrobial resistance and minimise the medicalisation of self-limiting illness. Little is known about whether homeopathic products might be used by some families as an alternative to antibiotics or the characteristics of such families. We used the Avon Longitudinal Study of Parents and Children (ALSPAC observational dataset to explore the hypothesis that the use of homeopathic products is associated with reduced antibiotic use in pre-school children and to identify characteristics of the families of pre-school children given homeopathic products. Methods Questionnaires data were completed by the parents of 9723 children while aged between 3–4.5 years in Bristol UK. Univariable and multivariable analyses were used to explore the relationships between antibiotic and homeopathic product use. Results Six percent of children had received one or more homeopathic products and 62% one or more antibiotics between the ages of 3 and 4.5 years. After adjustment for factors associated with antibiotic use, there was no association between homeopathic product and antibiotic use (adjusted OR = 1.02, 95% CI 0.84, 1.24. Factors independently associated with child homeopathic product use were: higher maternal education, maternal use of homeopathic products, maternal lack of confidence in doctors, mothers reporting that they were less likely to see doctor when the child was ill, children being given vitamins, watching less television and suffering from wheeze and food allergies. Conclusion In this observational study, the use of homeopathic products was not associated with decreased antibiotic consumption, suggesting the use of homeopathic product complements rather than competes with the use of antibiotics in pre-school children. The characteristics of mothers giving homeopathic products to their

    Full Text Available Could problem solving be the object of teaching in early education? Could children’s engagement in problem solving processes lead to skills and conceptual understanding development? Could appropriate teaching interventions scaffold children’s efforts? The sample consisted of 25 children attending public pre-school in Cyprus. The children were asked to construct different sized squares. Findings show that children responded positively to the problem and were successful in solving it. During the problem solving process children demonstrated development of skills and conceptual understanding. Teacher-children and children-children interactions played an important role in the positive outcome of the activity.

    Full Text Available Predictive relations from personality measures to children's social behaviour in pre-school were examined for 3 year old children (at Time 1; T1 who were reassessed one year later (at Time 2; T2. At both times, mothers and fathers separately rated children's personality characteristics using the Inventory of Child Individual Differences (Halverson et al., 2003, while the pre-school teachers assessed the same children on the Social Competence and Behavior Evaluation Scale (LaFreniere et al., 2001. Three general predictive models were examined, contemporaneous (at T1 and T2, longitudinal, and cumulative. Mother- and father-rated child personality was contemporaneously predictive of children's social behaviour as assessed by their pre-school teachers. The most consistent predictions across the spouses and at both times of measurement were obtained for child externalizing behaviour. More disagreeable and emotionally stable children, as opposed to their less disagreeable and more in stable counterparts, were concurrently observed to exhibit more externalizing tendencies during the time spent in pre-school. Maternal reports were longitudinally predictive of children's social competence and internalizing behaviour and the father reports predicted internalizing and externalizing behaviour one year later. Neuroticism at age 3 was consistently linked to internalizing tendencies at age 4 across parents both longitudinally and cumulatively. Father-rated Disagreeableness at age 3 was predictive of externalizing behaviour one year later in both longitudinal and cumulative models, while the contemporaneous information on child Disagreeableness and Neuroticism (reversed at T2, independent of the respective child traits at T1, significantly improved the cumulative predictions of externalizing behaviour from maternal reports. In general, child personality scores derived from maternal data sets were more powerful predictors of children's social behaviour across

    Full Text Available The paper describes the main results of a regional research problem dealing with education in pre-school age. It examines the effectiveness of the didactic conception of the process of phonemic stimulation in children from 3 to 5 years old. The pedagogical and didactic rationale of the process, viewed from the evolutionary, ontogeny, systemic perspective is explained. Likewise, possible scaffolding is illustrated. The suggested procedures focus the provision of support on a systematic and purposely practice which involve first the discrimination of non-verbal sounds and the discrimi-nation of verbal sound later, aiming to the creation of a phonological consciousness.

    Dziedzoave, Nanam Tay; Abass, Adebayo Busura; Amoa-Awua, Wisdom K.

    The high quality cassava flour (HQCF) industry has just started to evolve in Africa and elsewhere. The sustainability of the growing industry, the profitability of small- and medium-scale enterprises (SMEs) that are active in the industry and good-health of consumers can best be guaranteed through...... the adoption of proper quality and food safety procedures. Cassava processing enterprises involved in the productionof HQCF must therefore be commited to the quality and food safety of the HQCF. They must have the right technology, appropriate processing machhinery, standard testing instruments...... and the necessary technical expertise. This quality manual was therefore developed to guide small- to medium-scale cassava in the design and implematation of Hazard Analysis Critical Control Point (HACCP) system and Good manufacturing Practices (GMP) plans for HQCF production. It describes the HQCF production...

    To determine whether exposure to child-targeted fast-food (FF) television (TV) advertising is associated with children's FF intake in a non-experimental setting. Cross-sectional survey conducted April-December 2013. Parents reported their pre-school child's TV viewing time, channels watched and past-week FF consumption. Responses were combined with a list of FF commercials (ads) aired on children's TV channels during the same period to calculate children's exposure to child-targeted TV ads for the following chain FF restaurants: McDonald's, Subway and Wendy's (MSW). Paediatric and Women, Infants, and Children (WIC) clinics in New Hampshire, USA. Parents (n 548) with a child of pre-school age. Children's mean age was 4·4 years; 43·2 % ate MSW in the past week. Among the 40·8 % exposed to MSW ads, 23·3 % had low, 34·2 % moderate and 42·5 % high exposure. McDonald's accounted for over 70 % of children's MSW ad exposure and consumption. Children's MSW consumption was significantly associated with their ad exposure, but not overall TV viewing time. After adjusting for demographics, socio-economic status and other screen time, moderate MSW ad exposure was associated with a 31 % (95 % CI 1·12, 1·53) increase and high MSW ad exposure with a 26 % (95 % CI 1·13, 1·41) increase in the likelihood of consuming MSW in the past week. Further adjustment for parent FF consumption did not change the findings substantially. Exposure to child-targeted FF TV advertising is positively associated with FF consumption among children of pre-school age, highlighting the vulnerability of young children to persuasive advertising and supporting recommendations to limit child-directed FF marketing.

    We propose a high-quality compressive ghost imaging method based on projected Landweber regularization and guided filter, which effectively reduce the undersampling noise and improve the resolution. In our scheme, the original object is reconstructed by decomposing of regularization and denoising steps instead of solving a minimization problem in compressive reconstruction process. The simulation and experimental results show that our method can obtain high ghost imaging quality in terms of PSNR and visual observation.

    The rates of overweight and obesity among children have significantly increased in Chile. To assess the benefits of breastfeeding in preventing malnutrition by excessive intake of foods in Chilean pre-school children. A case-control study was conducted in 2011 on pediatric patients treated in a private Chilean healthcare center (San Joaquin Medical Center, Catholic University). Gender, age, weight, height, nutritional diagnosis, type of feeding during the first 6 months of life, socioeconomic status, parental education and obesity, television viewing, and kindergarten attendance were analyzed. A total of 209 patients were included in the study, 53.1% of whom were male, and 60.3% were predominantly breastfed for the first 6 months of life. More than half (51.7%) were eutrophic, 29.7% were overweight, and 18.6% obese. The patients were between the ages of 2 and 3 years 11 months. The crude Odds Ratio of breast-feeding versus formula during the first 6 months of life in patients with normal weight versus overweight children was 0.442 (95% CI 0.204-0.961). It was found that predominantly breastfeeding during the first 6 months of life acted as a protective factor against malnutrition by excessive intake of foods in Chilean pre-school children treated in this private medical center.

    Full Text Available The present study was designed to analyse the personality structure of children aged one to seven, as perceived by their kindergarten teachers. In addition, gender differences were examined to determine whether kindergarten teachers perceived the personality characteristics of toddler and pre-school girls differently than those of boys. 508 randomly-selected Slovenian children were assessed by their kindergarten teachers using adapted Flemish Big-Five Bipolar Rating Scales. Four-factor structures that explained more than two-thirds of the variance emerged for teachers' personality ratings of children in each of the three age groups: toddlers, three- to five-year-olds and five- to seven-year-olds. However, five of the twenty-five scales, four of them referring to the Conscientiousness dimension, did not appear to be relevant when assessing individual differences in the toddlerhood. Intellect/Openness, as observed for the toddler sample, and the combined Conscientiousness-Intellect/Openness factor, extracted for each of the two older age groups, accounted for the greatest part of the variance. Extroversion was obtained as a second factor in each of the three age groups, while Emotional Stability showed relatively less stability across these groups. Agreeableness was clearly differentiated only in the oldest age group, emerging there for the first time as an independent factor. A few gender differences were found to be significant within the two groups of pre-school children, with girls consistently being rated higher in terms of Conscientiousness-Intellect/Openness.

    The Ministry of Health of the Russian Federation acknowledges the sharp rise in the prevalence of congenital malformation in this country during the past 30 years. In 2010-2011, this pathology was estimated to occur in 3% of the children. It includes a variety of locomotor and coordination disorders of which the most widespread are infantile cerebral paralysis, ataxia, consequences of perinatal lesions of the central nervous system, etc. This article contains a detailed description of these locomotor and coordination disorders. The objective of the present work was to elaborate and evaluate the program for the formation of the self-maintenance skills in the pre-school children presenting with locomotor and coordination disorders under conditions of family guidance and education. The study was carried out from September 2013 till May 2014 based at MUP DOD "Semeiny klub Nadezhda" ("The Hope Family Club", Municipal unitary facility for children's additional education) and supported by B.N. El'tsin Ural Federal University. It included 10 children suffering from locomotor and coordination disorders of different severity and members of their families. The following methods were used: the self-service skills scorecard , monitoring formation of the motor skills, and Wilcoxon's T-test. The use of the program based on the cooperation with the children's families allowed to achieve positive dynamics in the patients' conditions. Moreover, 30% of them acquired the full scope of the self-maintenance skills. The most pronounced changes in the motor abilities were apparent in the movements of the upper and lower extremitis, walking, and motion in space. The proposed program for the formation of the self-maintenance skills in the pre-school children presenting with locomotor and coordination disorders proved to be highly efficacious. The study has demonstrated the importance of the parents' involvement in the process of formation of the self-maintenance skills and motor abilities

    The present study aimed to assess the prevalence of food neophobia in pre-school children and its association with eating habits, dietary intake and anthropometric parameters. Cross-sectional survey performed in 2012-2013. The Child Food Neophobia Scale (CFNS) adapted by Wardle, Carnell and Cooke was used to assess the level of food neophobia. Dietary intake was measured using an FFQ and dietary records from three days. Anthropometric measurements were taken to determine children's nutritional status and BMI was computed based on Polish growth charts. Wilcoxon's rank test and Pearson's rank-correlation coefficient were applied to compare the level of food neophobia and frequency of consumption of food products and nutrient intakes. Kindergartens in southern Poland located in or near Cracow. Three hundred and twenty-five pre-school children and their parents. Low neophobia was observed in 12·3 % and high neophobia in 10·8 % of the children examined. Children with a high level of neophobia were significantly less likely (Pfood neophobia were observed. High levels of neophobia are associated with diet variation and may enhance the risk of nutritional deficiencies in children.

    Problem of ensuring of joint high-quality when brazing different parts in power engineering is considered. To obtain high-quality joints it is necessary to correctly design brazed joint and to choose a gap width, overlap length and fillet radius; to clean up carefully the surfaces to be brazed and fix them properly one relative to another; to apply a solder so as to provide its flowing into the gap and sticking in it; to exactly regulate thermal conditions of brazing. High quality and reliability of brazed joints are ensured by the application of solders based on noble metals, and cheap solders based on nickel, manganese and copper. Joints brazed with nickel base solders may operate at temperatures as high as 888 deg C

    Full Text Available The approach of Total Quality Management (TQM has been even more common and most recently its use in high education has been discussed. Likewise the enterprises producing various products, universities have also inputs, processes, and outputs. Due to conditions of competition, universities have to improve the qualities of these inputs, processes, and outputs, according to satisfaction, demands, and expectations of internal and external customers. If the TQM has been implemented in the universities with a manner that aims for customer satisfaction (students, lecturers, public and private establishments, and families, supports constant development, ensures participatory approach, and encourages working in groups, it will provide universities with effectiveness, efficiency, dynamics, and economics. In this study, common problems of universities, definitions of quality and TQM in high education, customer concept at universities, and factors affecting the quality of education have been explained. Besides, in order TQM approach to be successfully implemented in the universities, various suggestions have been presented.

    The Common Risk Factor Approach proposes that public health efforts can be improved by multiple agencies working together on a shared risk factor. The present study aimed to assess the acceptability to parents, dental practice staff and commissioners of the delivery of dietary advice in the dentistry setting in order to address obesity. Semi-structured focus groups with dental practice staff and one-to-one interviews with parents of pre-school children and public health commissioners involved in an oral health promotion initiative delivering dietary advice in dental surgeries. Data were analysed using the Framework Approach. General dental practice surgeries and pre-schools in areas of high deprivation in north-east England. Parents (n 4), dental practice staff (n 23) and one commissioner. All participants found acceptable the concept of delivering public health messages in non-conventional settings. Dental practice staff were concerned about the potential for conflicting messages and deprioritisation of oral health advice, and they identified practical barriers to delivery, such as lack of training. Parents were very apprehensive about the potential of such approaches to stigmatise overweight children, including bullying. Uncertainty over the causes of obesity led to confusion about its solutions and the roles of public health and health care. Major concerns about the implementation of the Common Risk Factor Approach were raised by parents and dental practice staff. Specific dietary guidance for both oral health and healthy weight, as well as further research into issues of suitability, feasibility and stigmatisation, are needed.

    Full Text Available Objective: The present research was conducted to study the effect of play therapy on reducing behavioral problems of mal-adjusted children (children with oppositional defiant disorder. Method: By using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected, and among kindergartens of these areas, 3 kindergartens under the support of welfare organization were randomly selected. From pre-school children of these 3 kindergartens, 40 children that could have behavioral disorder according to their teachers and parents complaints, were carefully tested, and among them, by the results obtained from child symptom inventory questionnaire (CSI-4, teacher's form, and a researcher-made self-control checklist, 16 children who showed severe symptoms of oppositional defiant disorder were selected, and they were randomly divided into control and experimental group. This research is quasi-experimental, and is done by the use of pre-test, post-test, and control group. Results: values of calculated F for oppositional defiant disorder in control and experimental group is meaningful after fixing the effect of pre-test (F(1,12=74/94, P<0/001 so there is a meaningful difference between means of disobedience disorder post-test scores in experimental and control group by having the fixed effect of pre-test effect. Comparison of adjusted means of 2 groups shows that the mean of attention-deficit hyperactivity disorder (ADHD in experimental group (M=14/09 is lower than control group (M=36/66. Therefore, applying play therapy in experimental group in comparison with control group, who did not receive these instructions, caused reduction in attention-deficit hyperactivity disorder (ADHD in pre-school children. Conclusion: Results of this research show that the children's disobedience is reduced by benefiting from play therapy.

    To identify sociodemographic and environmental correlates of sweetened beverages (regular soft drinks, fruit juice) among children of pre-school age. Children's dietary intake, food behaviours and screen time were measured by parental report. A Geographic Informational System was used to assess the number of grocery stores and fast-food restaurants available within 1 km of the children's residence. Multivariate log-binomial regression models were constructed to determine correlates of drinking soft drinks during the previous week. Edmonton region, Canada. Children aged 4 and 5 years (n 2114) attending a public health unit for immunization were recruited for a cohort study on determinants of childhood obesity, between 2005 and 2007. Children from neighbourhoods with low socio-economic status (relative risk (RR) = 1·17, 95 % CI 0·98, 1·40) or who participated in >2 h of screen time daily (RR = 1·28, 95 % CI 1·13, 1·45) were significantly more likely to have consumed regular soft drinks within the last week. Those who lived within 1 km of a grocery store were significantly less likely to consume regular soft drinks (RR = 0·84, 95 % CI 0·73, 0·96). Children who participated in >2 h of screen time daily (RR = 1·16, 95 % CI 1·06, 1·27) were more likely to exceed the recommended weekly number of servings of fruit juice. Socio-economic and built environment factors are associated with soft drink consumption in children of pre-school age. These findings may help health professionals to advocate for policies that reduce soft drink consumption among children.

    In high-consequence engineering organizations, such as Sandia, quality assurance may be heavily dependent on staff competency. Competency-dependent quality assurance models are at risk when the environment changes, as it has with increasing attrition rates, budget and schedule cuts, and competing program priorities. Risks in Sandia's competency-dependent culture can be mitigated through changes to hiring, training, and customer engagement approaches to manage people, partners, and products. Sandia's technical quality engineering organization has been able to mitigate corporate-level risks by driving changes that benefit all departments, and in doing so has assured Sandia's commitment to excellence in high-consequence engineering and national service.

    1999-04-01

    iron deficiency anaemia (IDA) is a public health problem throughout the world. Childhood iron deficiency anaemia. A prospective survey (systematic, cluster sampling) was carried out among pre-school children in Alshigla area (Khartoum State), to study the prevalence and aetological factors of IDA. 170 children selected for general nutritional evaluation, 110 of them for haemoglobin levels and morphological classification of anaemia, 70 for further investigations(serum iron, unsaturated iron binding capacity, total iron binding capacity). The population at Alshigla were living in poor condition 85.3% relied on water brought by tankers which showed poor hygienic standard, 90% lived in extended families 54.1% had income level less than LS 3000/day irrespective of family size or mode of spending. A sample of 170 children showed (84.1%) normal nutritional status with 4.7% severe cases with high consumption of cereals low meat, fish and poultry group and vitamin C(22.9%). Disease episodes showed 67.7% had diarrhoea, 22.4% had giardia, 12.9% had malaria and 10.6% had worm infestation. This most probably due to unsanitary living condition. Haemoglobin analysis using Enzyme Linked Immunosorbent assay technique (ELISA) for 110 of the children, showed high prevalence of anaemia (96.4%), 66% prevalence of IDA. Further haematological investigations of 50 of the children confirmed them as IDA cases.Thus the high prevalence of IDA in Alshigla was multi-factorial, inadequate take of dietary iron and of vitamin C, high intake of cereals and legumes, low intake of meat, poultry and fish group (MPF),and high tea consumption, thus food provides inadequate supply of iron and were rich in inhibitors of iron absorption. In addition episodes of diseases that may influence food (hence iron) utilisation contributed to the prevalence of IDA

    Full Text Available Abstract Background Sedentary behavior is considered a separate construct from physical activity and engaging in sedentary behaviors results in health effects independent of physical activity levels. A major source of sedentary behavior in children is time spent viewing TV or movies, playing video games, and using computers. To date no study has examined the impact of neighborhood socioeconomic status (SES on pre-school children's screen time behavior. Methods Proxy reports of weekday and weekend screen time (TV/movies, video games, and computer use were completed by 1633 parents on their 4-5 year-old children in Edmonton, Alberta between November, 2005 and August, 2007. Postal codes were used to classified neighborhoods into low, medium or high SES. Multiple linear and logistic regression models were conducted to examine relationships between screen time and neighborhood SES. Results Girls living in low SES neighborhoods engaged in significantly more weekly overall screen time and TV/movie minutes compared to girls living in high SES neighborhoods. The same relationship was not observed in boys. Children living in low SES neighborhoods were significantly more likely to be video game users and less likely to be computer users compared to children living in high SES neighborhoods. Also, children living in medium SES neighborhoods were significantly less likely to be computer users compared to children living in high SES neighborhoods. Conclusions Some consideration should be given to providing alternative activity opportunities for children, especially girls who live in lower SES neighborhoods. Also, future research should continue to investigate the independent effects of neighborhood SES on screen time as well as the potential mediating variables for this relationship.

  2. Social disparities in children's vocabulary in early childhood. Does pre-school education help to close the gap?

    2011-03-01

    Children start school with differing levels of skills. Thus, children of different social origin have different probabilities of educational success right from the start of their school career. This paper analyses how the gap in language abilities of children with different social backgrounds develops from age three to five. A focus lies on the question whether pre-school education can help to close this gap. The data of the UK Millennium Cohort Study (MCS) show that children's score on a standardized vocabulary test strongly depends on their parents' education. These social differences remain stable or even increase slightly over the two-year period. Using fixed effect models, it is demonstrated that children of higher educated parents can improve their vocabulary more strongly than children whose parents have a lower educational level. Participation in an early education institution positively affects the vocabulary development of children with lower educated parents while there is no significant pre-school effect for children of higher educated parents. The results indicate that pre-school attendance does not lead to a catching-up process of children with lower educated parents. But without pre-school attendance, the gap between children of higher and lower educated parents widens even further. © London School of Economics and Political Science 2011.

    2010-09-15

    Hydrotreating of vegetable oils is novel process for producing high quality renewable diesel. Hydrotreated vegetable oils (HVO) are paraffinic hydrocarbons. They are free of aromatics, have high cetane numbers and reduce emissions. HVO can be used as component or as such. HVO processes can also be modified to produce jet fuel. GHG savings by HVO use are significant compared to fossil fuels. HVO is already in commercial production. Neste Oil is producing its NExBTL diesel in two plants. Production of renewable fuels will be limited by availability of sustainable feedstock. Therefore R and D efforts are made to expand feedstock base further.

    The post dry-out heat transfer regime of the flow boiling curve was investigated experimentally for high pressure water at high qualities. The test section was a short round tube located downstream of a hot patch created by a temperature controlled segment of tubing. Results from the experiment showed that the distance from the dryout point has a significant effect on the downstream temperatures and there was no unique boiling curve. The heat transfer coefficients measured sufficiently downstream of the dryout point could be correlated using the Heineman correlation for superheated steam, indicating that the droplet deposition effects could be neglected in this region

    Full Text Available There is a growing use of dietary supplements in many countries including China. This study aimed to document the prevalence of dietary supplements use and characteristics of Chinese pre-school children using dietary supplements in Australia and China. A survey was carried out in Perth, Western Australia of 237 mothers with children under five years old and 2079 in Chengdu and Wuhan, China. A total of 22.6% and 32.4% of the Chinese children were taking dietary supplements in Australia and China, respectively. In China, the most commonly used dietary supplements were calcium (58.5% and zinc (40.4%, while in Australia, the most frequently used types were multi-vitamins/minerals (46.2% and fish oil (42.3%. In Australia, “not working”, “never breastfeed”, “higher education level of the mother” and “older age of the child” were associated with dietary supplement use in children. In China, being unwell and “having higher household income” were significantly related to dietary supplement usage. Because of the unknown effects of many supplements on growth and development and the potential for adverse drug interactions, parents should exercise caution when giving their infants or young children dietary supplements. Wherever possible it is preferable to achieve nutrient intakes from a varied diet rather than from supplements.

    Malnutrition can be defined as a state of nutrition where the weight for age, height for age and weight for height indices are below -2 Z-score of the NCHS reference. It has posed a great economic burden to the developing world. The objective of this study is to assess the prevalence of malnutrition among pre-school children in Abakiliki in Ebonyi state of Nigeria. This is a cross-sectional studies that assess the prevalence of malnutrition and associated factors among children aged 1-5 years attending nursery and primary schools. Nutritional assessment was done using anthropometry and clinical examination. A total of 616 children aged one to 5 years were enrolled into this study. Three hundred and sixty-seven (59.6%) were males while 249 (40.4%) were females. Sixty of the 616 children (9.7%) had acute malnutrition based on WHZ-score. Moderate acute malnutrition (MAM) was present in 33 children (5.3%) while 27 (4.4%) had severe acute malnutrition. The prevalence of global and severe acute malnutrition using z-score is 9.7% and 4.4% respectively while that of stunting is 9.9% with a male preponderance.

    Full Text Available The pre-school period plays a very important role in the language development. One of the significant indicators of this development is the phonological awareness. Some of the previous studies reported the presence of the relation between the phonological awareness and musical abilities. Our main goal was to examine this relation with the Test of the phonological awareness and the Test of musical abilities on 67 Slovene preschool children, aged from 5 to 6. We also wanted to investigate the differences between boys (N = 36 and girls (N = 31 and the differences between two age groups (aged from 5 to 5.5 years, N = 32, and from 5.5 to 6 years, N = 35. The results confirmed the connection between musical abilities and the phonological awareness. They also indicated that the recognition of the first and the last phoneme is related to melodic awareness and that phoneme merging is mainly related to rhythm awareness. No significant differences were found between male and female children or between the groups of the children of different ages.

    Background Hookworm infections are an important cause of (severe) anemia and iron deficiency in children in the tropics. Type of hookworm species (Ancylostoma duodenale or Necator americanus) and infection load are considered associated with disease burden, although these parameters are rarely assessed due to limitations of currently used diagnostic methods. Using multiplex real-time PCR, we evaluated hookworm species-specific prevalence, infection load and their contribution towards severe anemia and iron deficiency in pre-school children in Malawi. Methodology and Findings A. duodenale and N. americanus DNA loads were determined in 830 fecal samples of pre-school children participating in a case control study investigating severe anemia. Using multiplex real-time PCR, hookworm infections were found in 34.1% of the severely anemic cases and in 27.0% of the non-severely anemic controls (panemia (adjusted odds ratio: 2.49 (95%CI 1.16–5.33) and 9.04 (95%CI 2.52–32.47) respectively). Iron deficiency (assessed through bone marrow examination) was positively associated with intensity of A. duodenale infection (adjusted odds ratio: 3.63 (95%CI 1.18–11.20); 16.98 (95%CI 3.88–74.35) and 44.91 (95%CI 5.23–385.77) for low, moderate and high load respectively). Conclusions/Significance This is the first report assessing the association of hookworm load and species differentiation with severe anemia and bone marrow iron deficiency. By revealing a much higher than expected prevalence of A. duodenale and its significant and load-dependent association with severe anemia and iron deficiency in pre-school children in Malawi, we demonstrated the need for quantitative and species-specific screening of hookworm infections. Multiplex real-time PCR is a powerful diagnostic tool for public health research to combat (severe) anemia and iron deficiency in children living in resource poor settings. PMID:22514750

    Dental caries is highly prevalent and a significant public health problem among children throughout the world. Epidemiological data regarding prevalence of dental caries amongst Pakistani pre-school children is very limited. The objective of this study is to determine the frequency of dental caries among pre-school children of Saddar Town, Karachi, Pakistan and the factors related to caries. A cross-sectional study of 1000 preschool children was conducted in Saddar town, Karachi. Two-stage cluster sampling was used to select the sample. At first stage, eight clusters were selected randomly from total 11 clusters. In second stage, from the eight selected clusters, preschools were identified and children between 3- to 6-years age group were assessed for dental caries. Caries prevalence was 51% with a mean dmft score being 2.08 (±2.97) of which decayed teeth constituted 1.95. The mean dmft of males was 2.3 (±3.08) and of females was 1.90 (±2.90). The mean dmft of 3, 4, 5 and 6-year olds was 1.65, 2.11, 2.16 and 3.11 respectively. A significant association was found between dental caries and following variables: age group of 4-years (p-value dental plaque (p-value dental caries coupled with a high prevalence of unmet dental treatment needs. Association between caries experience and age of child, consumption of non-sweetened milk, dental plaque and poor oral hygiene had been established.

A Class Action Research was applied in this study. The data was collected through observation checklist, sequence of cycles and interview transcript. Then, building on the analysis of the collected data, it further discusses the vocabulary development of YL and provides suggestions for TEYL. This study revealed that; (1 most of the students developed their English vocabularies gradually by flashcards. (2 These result indicated that TEYL especially kindergarten students by using flashcards could give significant vocabularies development in learning process. Flashcards is one of the simplest and effective teaching materials for teaching YL vocabulary due to the fact that flashcards are categorized based on themes with full colored pictures which attractive for YL. As this study showed the students were engaged with the topics given since the teachers used flashcards to teach English vocabulary. It was difficult to make engagement with YL in English teaching and learning because YL have different mood, self-motivation, and self-confidence which influenced to the willingness in grasping the lesson. Finally, through this based-picture learning, the students indicated that their progress in vocabulary development although this phenomena was commonly happened in TEFL for YL that lead to teaching method done by English teachers who are required to do more innovation toward their teaching method, to develop sufficient knowledge and to use proper teaching media.

    The aim of this paper is to assess the spatial distribution of nutritional status of children of less than three years through Z-scores of weight-for-age, height-for-age and weight-for-height using data collected by the National Family Health Survey (NFHS-2, 1998-99), India. The nutritional status of pre-school children was regressed on different socio-demographic factors after eliminating the effect of age. The data show that there are gender differences and spatial variations in the nutritional status of children in India. Gender difference is not very pronounced and almost disappears when the effects of age and socio-demographic variables are removed. The spatial difference, especially the rural-urban difference, was found to be very large and decreased substantially when the effects of age and socioeconomic variables were removed. However, the differences were not close to zero. All the variables were found to affect significantly the nutritional status of children. However, the literacy of mothers did not affect height-for-age significantly. The weight-for-age and height-for-age scores showed a dismal picture of the health condition of children in almost all states in India. The worst affected states are Bihar, Madhya Pradesh, Orissa and Uttar Pradesh. Assam and Rajasthans are also lagging behind. Weight-for-height scores do not give a clear picture of state-wise variation. Goa, Kerala and Punjab are the three most developed states in India and also have the lowest percentages of underweight children according to the Z-scores. Along with these three states come the north-eastern states where women are well educated. Thus overall development, enhancement of level of education and low gender inequality are the key factors for improvement in the health status of Indian children.

    Pre-school communication problems are common, with implications for school readiness and educational achievement. Help is available from a variety of community healthcare providers. This study examined the extent to which help is received, and the predictors of service receipt. Prospective community study, in Melbourne, Victoria. At age 4 years, we assessed the speech, receptive and expressive language and fluency of 1607 children and gave feedback to their parents. At age 5 years, 983 families provided data on service use for communication problems between and 4 and 5 years. We compared service use between participants with and without impairment, and used logistic regression to estimate the strength of association between potential predictors (gender, socio-economic status, maternal education, English-speaking background status, family history of speech and language problems and parent concern) and service use (binary outcome). Data were available for both communication status and service use for 753 children. Only 44.9% of the 196 children with communication impairment received help from a professional. Furthermore, 7% of the 557 that did not meet criteria for communication impairment nevertheless received help from a professional. Parent concern was the strongest predictor of service use (adjusted odds ratio = 9.0; 95% CI: 5.6-14.8). Both over- and under-servicing for communication problems were evident. This study shows that accessing help for communication problems requires more than simply informing parents about the problem and having services available; there is a need for systematic support to get the right children to services. © 2013 John Wiley & Sons Ltd.

    Although the abdominopelvic CT findings of abdominal trauma in children have been described, little has been written about the subset of children who are victims of abuse. Our purpose is to describe abdominopelvic injuries in abused pre-school-age children as identified on CT. An IRB-approved retrospective review of our institutional child abuse registry was performed. Searching a 14-year period, we identified 84 children ≤ 5 years of age with medically diagnosed abuse who underwent CT. We reviewed imaging studies, operative reports, autopsy findings and patient outcomes. Consensus review of the CT examinations was performed by CAQ-certified pediatric radiologists, and findings were categorized as normal or by injury types (solid organ versus bowel). The injuries were analyzed in light of existing literature on pediatric accidental and non-accidental injuries. Of the 84 children, 35 (41.7%) had abdominal injuries. Abdominal injuries included liver (15), bowel (13), mesentery (4), spleen (6), kidneys (7), pancreas (4) and adrenal glands (3). Of these children, 26% (9/35) required surgical intervention for bowel, mesenteric and pancreatic injuries. Another 9/35 children died, not as a result of abdominal injuries but as a direct result of inflicted intracranial injuries.

    Although the abdominopelvic CT findings of abdominal trauma in children have been described, little has been written about the subset of children who are victims of abuse. Our purpose is to describe abdominopelvic injuries in abused pre-school-age children as identified on CT. An IRB-approved retrospective review of our institutional child abuse registry was performed. Searching a 14-year period, we identified 84 children {<=} 5 years of age with medically diagnosed abuse who underwent CT. We reviewed imaging studies, operative reports, autopsy findings and patient outcomes. Consensus review of the CT examinations was performed by CAQ-certified pediatric radiologists, and findings were categorized as normal or by injury types (solid organ versus bowel). The injuries were analyzed in light of existing literature on pediatric accidental and non-accidental injuries. Of the 84 children, 35 (41.7%) had abdominal injuries. Abdominal injuries included liver (15), bowel (13), mesentery (4), spleen (6), kidneys (7), pancreas (4) and adrenal glands (3). Of these children, 26% (9/35) required surgical intervention for bowel, mesenteric and pancreatic injuries. Another 9/35 children died, not as a result of abdominal injuries but as a direct result of inflicted intracranial injuries. Our data indicate that abdominal injuries in abused children present in a pattern similar to that of children with accidental abdominal trauma, underscoring the need for vigilance and correlative historical and clinical data to identify victims of abuse. Mortality in abused children with intra-abdominal injury was frequently related to concomitant head injury. (orig.)

    Little is known regarding the extent of visual impairment amongst pre-school children in Malaysia. To determine the prevalence of visual impairment and amblyopia in Malaysian preschool children. A cross-sectional, population-based study was conducted on children aged four to six years from 51 participating kindergartens in the district of Segamat, Johor, Malaysia from 20 March 2016 to 6 April 2016. All subjects had initial eye screening consisting of LogMar visual acuity, orthoptics examination and Spot vision screener assessment. Subjects who failed the initial eye screening were invited for a formal eye assessment consisting of cycloplegic refraction and a comprehensive ocular examination. Definitions of visual impairment and amblyopia were based on the Multi-Ethnic Pediatric Eye Disease Study criteria. A total of 1287 children were recruited. Mean subject age was 5.03 (SD:0.77) and males represented 52.3% of subjects. Subjects by ethnicity were Malay (54.8%), Chinese (27.7%), Indian (15.6%) and Orang Asli (1.9%). Formal eye assessment was required for 221 subjects and 88.8% required ophthalmic intervention. Refractive error, representing 95.4% of diagnosed ocular disorders, comprised of astigmatism (84%), myopia (9%) and hypermetropia (6.9%). With-the-rule astigmatism was present in 93.4% of the subjects with astigmatism. Visual impairment was present in 12.5% of our subjects, with 61% having bilateral visual impairment. Of the subjects with visual impairment, 59.1% had moderate visual impairment. The prevalence of amblyopia was 7.53%, and 66% of the amblyopic subjects had bilateral amblyopia. Our study highlights an urgent need for initiation of preschool vision screening in Malaysia.

    Detection of vision defects of a child without professional knowledge is not easy. Very often, the parents of a small child does not know that their child sees incorrect. Also the youngster, not knowing any other way of seeing, does not know that it is not the best. While the vision of a small child is not yet fully formed, it is worth checking them very early. Defects detected early gives opportunity for the correction of anomalies, which might give the effect of the normal development of vision. According to the indications, the American Optometric Association (AOA) control eye examination should be performed between the ages of 6 months to 3 years, before going to school and then every two years. Members of SPIE Student Chapter, in cooperation with the Visual Optics Group working on the Department of Optics and Photonics (Faculty of Fundamental Problems, Wroclaw University of Science and Technology) for 6 years offer selected kindergartens of Wroclaw participation in project "Screening vision tests in pre-school children". Depending on the number of involved members of the student chapter and willing to cooperate students of Ophthalmology and Optometry, vision screening test was carried out in up to eight kindergartens every year. The basic purpose of screening vision test is to detect visual defects to start the correction so early in life as possible, while increasing the efficiency of the child's visual potential. The surrounding community is in fact more than enough examples of late diagnose vision problems, which resulted in lack of opportunity or treatment failure

    Spirometry is the most used test to evaluate pulmonary function. Guidelines that defined acceptability and repeatability criteria for its implementation and interpretation among preschoolers were published in 2007. Our objective was to quantify the actual compliance with these criteria among pre-school patients. A review was performed on the baseline spirometry measured in patients aged 2 to 5 years in the Pediatric Respiratory Laboratory of the Pontificia Universidad Católica de Chile, who were admitted due to recurrent or persistent coughing or wheezing. Only those results obtained in patients who took the test for the first time were considered. They were analyzed by international standards. A total of 93 spirometry results (mean age 57.4 ± 8.6 months, 48 males) were obtained, of which 44 (47%) met all acceptable criteria, 87 (93%) obtained expiratory time of ≥ 0.5seconds, and 67 (72%) of the patients had an end-expiratory flow of ≤10% from peak flow. The variation in the measurement of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) was very low (intraclass correlation coefficient > 0.9). It was possible to meet the acceptability and repeatability criteria for spirometry among pre-school children in our Center, which was similar to previous reports. As in older children, this test is fully recommended for pre-school children who require lung function studies. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level. In this paper, the effectiveness of a programme comprising several components that are meant to consolidate mathematical concepts and abilities at the pre-school level is analyzed. The instructional methodology of this programme is compared to other methodologies. One-hundred 5-6 year-old children made up the sample that was distributed in the following conditions: (1) traditional methodology; (2) methodology with perceptual and manipulative components, and (3) methodology with language and playful components. Mathematical competence was assessed with the Mathematical Criterial Pre-school Test and the subtest of quantitative-numeric concepts of BADyG. Participants were evaluated before and after the academic course during which they followed one of these methodologies. The results show that the programme with language and playful components is more effective than the traditional methodology (p<.000) and also more effective than the perceptual and manipulative methodology (p<.000). Implications of the results for instructional practices are analyzed.

    A method is described herein for the providing of high quality graphene layers on silicon carbide wafers in a thermal process. With two wafers facing each other in close proximity, in a first vacuum heating stage, while maintained at a vacuum of around 10.sup.-6 Torr, the wafer temperature is raised to about 1500.degree. C., whereby silicon evaporates from the wafer leaving a carbon rich surface, the evaporated silicon trapped in the gap between the wafers, such that the higher vapor pressure of silicon above each of the wafers suppresses further silicon evaporation. As the temperature of the wafers is raised to about 1530.degree. C. or more, the carbon atoms self assemble themselves into graphene.

    Industrial X-ray-CT-scanners, which provide cross-sectional images of a tested sample without destroying it, are attracting attention as a new nondestructive inspection device. In 1982, Toshiba commenced the development of industrial CT scanners, and introduced the 'TOSCANER' -3000 and-4000 series. Now, the state of the art 'TOSCANER'-20000 series of CT systems has been developed incorporating the latest computer tomography and image processing technology, such as the T9506 image processor. One of the advantages of this system is its applicability to a wide range of X-ray energy . The 'TOSCANER'-20000 series can be utilized for inspecting castings and other materials with relatively low-transparency to X-rays, as well as ceramics, composite materials and other materials with high X-ray transparency. A further feature of the new system is its high-picture quality, with a high-spatial resolution resulting from a pixel size of 0.2x0.2(mm). (author)

    1999-01-01

    This thesis is concerned with the study of fundamental and defect induced optical properties of synthetic diamond grown using high pressure, high temperature (HPHT) synthesis or chemical vapour deposition (CVD). The primary technique used for investigation is cathodoluminescence (including imaging and decay-time measurements) in addition to other forms of optical spectroscopy. This thesis is timely in that the crystallinity and purity of synthetic diamond has increased ten fold over the last few years. The diamond exciton emission, which is easily quenched by the presence of defects, is studied in high quality samples in detail. In addition the ability now exists to engineer the isotopic content of synthetic diamond to a high degree of accuracy. The experimental chapters are divided as follows: Chapter 2: High resolution, low temperature spectra reveal a splitting of the free-exciton phonon recombination emission peaks and the bound-exciton zero phonon line. Included are measurements of the variation in intensity and decay-time as a function of temperature. Chapter 3: The shift in energy of the phonon-assisted free-exciton phonon replicas with isotopic content has been measured. The shift is in agreement with the results of interatomic force model for phonon scattering due to isotope disorder. Chapter 4: A study of the shift in energy with isotopic content of the diamond of the GR1 band due to the neutral vacancy has allowed a verification of the theoretical predictions due to the Jahn Teller effect. Chapter 5: The spatial distribution of the free-exciton luminescence is studied in HPHT synthetic and CVD diamond. A variation in intensity with distance from the surface is interpreted as a significant non-radiative loss of excitons to the surface. Chapter 6: The decay-times of all known self-interstitial related centres have been measured in order to calculate the concentration of these centres present in electron irradiated diamond. (author)

    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. The existing electric grid infrastructure in the US in particular poses significant limitations on wind power expansion. In this presentation we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets are presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. The need for high-resolution weather data pushes modeling towards finer scales and closer synchronization. We also present how we anticipate such datasets developing in the future, their benefits, and the challenges with using and disseminating such large amounts of data.

    Full Text Available Preschool upbringing of children with developmental difficulties is the first link in the system of education and upbringing and at the same time the utmost segment in the system of integrational rehabilitation.Initiating the process of preschool upbringing and adequate organized treatment at early age, permits support of the development and maximum usage of the remained capabilities of children with developmental difficulties.The newest world experiences show that the upbringing and educational integration of children with developmental difficulties as asegment of the social integration, should set the main conditions in the frames of upbringing education and rehabilitational continuity and support the minimal restrictive environment for their development.In the pre-school institutions that function on the territory of the Republic of Macedonia, an indifferent attitude towards the children with developmental difficulties is present, due to the uninformed educators for the characteristics and capabilities of these children and their believes for the negative influence of the children with developmental difficulties on the children without impairments, that implicates involvement of subsidery defectological education of present employed staff in the mainstream preschool institutions, also including defectologists in kindergartens for work with children with special difficulties in their development. Also, the data about the educator’s attitude in the mainstream preschool institutions is disturbing, so that they put the accent on the obligation for reducing of the program for work with handicapped children, not taking into consideration that subsidery, special forms and methods are needed beside the programs that are for the main stream group.The goal of our paper is to point out the need of involving of children with light developmental difficulties; the existence of special team in the preschool institutions when involving children with

    Full Text Available The issue, disclosed in the article, is still relevant, because it supports a child’s creative activity through his/her contact with the literature. Moreover, a book genres influence the linguistic awareness, aesthetic sensitivity, develops the imagination and the ability to speak properly. Developing reading habits and close contact with art positively affects the child. So the aim of the article is to show the importance of supporting the child in creative tasks using the fiction texts. Much attention is given to the fact that literature for children in pre-school, school and home education influences the expansion of a child’s vocabulary and imagination. Constant complementation of teachers’ and parents’ activities in shaping reading interests of children influences their versatile development. Books evoke emotions, they teach how to behave in a proper way and they enrich the awareness of the surrounding world. Both teachers and parents should choose the right texts for a young reader taking into consideration his/her perceptive skills. Ever present humour in belles-lettres for children (vocabulary, situational humour or the protagonists in the books definitely provides children with joy and positive emotions. The contact with belles-lettres texts allows to develop interests of children connected with stage, theatre or music which is frequently a meaningful element of plays based on books for young children. It is also reported that both poetry and prose texts should be included into young readers’ collection. But the text should be adapted to the child’s perceptual abilities, in terms of form, content, and language. Family reading is important for developing the child’s reading interests, becoming one of the participants influencing the cultural environment of the family. The author concludes that supporting children in creative tasks using fiction texts and their forms such as theater, press, radio, television develops

    2009-09-01

    There is a growing evidence base showing the efficacy of school-based interventions to prevent conduct problems but few evaluations have addressed teachers' perceptions of these programmes. Teachers' views on the acceptability, feasibility and usefulness of an intervention will influence implementation fidelity and programme sustainability and can help further our understanding of how the intervention works and how it may be improved. A pilot study of the Incredible Years Teacher Training Programme supplemented by a curriculum unit on social and emotional skills was conducted in inner-city pre-schools in Kingston, Jamaica. Three pre-schools comprising 15 classrooms participated in the intervention which involved seven monthly teacher workshops and 14 weekly child lessons in each class. At the end of the intervention in-depth individual interviews were conducted with each intervention teacher. Teachers reported benefits to their own teaching skills and professional development, to their relationships with children and to the behaviour, social-emotional competence and school readiness skills of the children in their class. Teachers also reported benefits to teacher-parent relationships and to children's behaviour at home. A hypothesis representing the teachers' perceptions of how the intervention achieved these benefits was developed. The hypothesis suggests that intervention effects were due to teachers' gains in skills and knowledge in three main areas: (1) a deeper understanding of young children's needs and abilities; (2) increased use of positive and proactive strategies; and (3) explicitly teaching social and emotional skills. These changes then led to the variety of benefits reported for teachers, children and parents. Teachers reported few difficulties in implementing the majority of strategies and strongly recommended wider dissemination of the intervention. The intervention was valued by Jamaican pre-school teachers and teachers felt they were able to

    The goal of the program was to demonstrate a 45 lumen per watt white light device based upon the use of multiple emission colors through the use of solution processing. This performance level is a dramatic extension of the team's previous 15 LPW large area illumination device. The fundamental material system was based upon commercial polymer materials. The team was largely able to achieve these goals, and was able to deliver to DOE a 90 lumen illumination source that had an average performance of 34 LPW a 1000 cd/m{sup 2} with peak performances near 40LPW. The average color temperature is 3200K and the calculated CRI 85. The device operated at a brightness of approximately 1000cd/m{sup 2}. The use of multiple emission colors particularly red and blue, provided additional degrees of design flexibility in achieving white light, but also required the use of a multilayered structure to separate the different recombination zones and prevent interconversion of blue emission to red emission. The use of commercial materials had the advantage that improvements by the chemical manufacturers in charge transport efficiency, operating life and material purity could be rapidly incorporated without the expenditure of additional effort. The program was designed to take maximum advantage of the known characteristics of these material and proceeded in seven steps. (1) Identify the most promising materials, (2) assemble them into multi-layer structures to control excitation and transport within the OLED, (3) identify materials development needs that would optimize performance within multilayer structures, (4) build a prototype that demonstrates the potential entitlement of the novel multilayer OLED architecture (5) integrate all of the developments to find the single best materials set to implement the novel multilayer architecture, (6) further optimize the best materials set, (7) make a large area high illumination quality white OLED.

    Fang, W.; Yamilov, A.; Cao, H.

    2005-01-01

    We present a numerical study of the high-quality modes in two-dimensional dielectric stadium microcavities. Although the classical ray mechanics is fully chaotic in a stadium billiard, all of the high-quality modes show a 'strong scar' around unstable periodic orbits. When the deformation (ratio of the length of the straight segments over the diameter of the half circles) is small, the high-quality modes correspond to whispering-gallery-type trajectories and their quality factors decrease monotonically with increasing deformation. At large deformation, each high-quality mode is associated with multiple unstable periodic orbits. Its quality factor changes nonmonotonically with the deformation, and there exists an optimal deformation for each mode at which its quality factor reaches a local maximum. This unusual behavior is attributed to the interference of waves propagating along different constituent orbits that could minimize light leakage out of the cavity

    Full Text Available This paper discusses a project with a small group of children learning English as an a language (EAL at a pre-school in Scotland. The project however could be replicated across the globe, in any classroom with a diverse range of learners, with particular benefit to minority and newly arrived migrant children. At the project’s core was the aim to bring the children’s first language and culture into the classroom, drawing in particular on Cummin’s (1984 Common Underlying Proficiency model, which asserts that knowledge of one language can assist learners in their acquisition of another. The project used multicultural picturebooks to validate the learner’s experiences and culture, and then called on parents’ funds of knowledge to make the children’s first language visible in the classroom. This joint working between the children, parents and the pre-school culminated in the production of a multilingual collage – a prominent display that recognises the value of the children’s first language in the classroom, builds bridges between home and school and is reflective, and proud, of an increasingly multilingual Scotland.

    To report on the prevalence of overweight and obesity among pre-school children in Kenya and examine the associations between childhood overweight and selected maternal and child-related factors. Demographic Health Survey data, multistage stratified cluster sampling methodology. Rural and urban areas of Kenya. A total of 1495 children between the ages of 3 and 5 years in Kenya. Over 30 % of the children were stunted, approximately 16 % were underweight, 4 % were wasted, approximately 18 % were overweight and 4 % were obese; 8 % were both overweight/obese and stunted. Maternal overweight and obesity, higher levels of maternal education, being a large or very large child at birth, and being stunted were each associated with higher odds of overweight and obesity among Kenyan children. Older children and large household size were each associated with lower odds of overweight and obesity among Kenyan children. The analysis demonstrates the presence of under- and overnutrition among Kenyan pre-school children and the importance of focusing on expanding efforts to prevent and treat malnutrition within this population. It also identifies some of the modifiable factors that can be targeted in these efforts.

    Poor childhood diet is a major risk factor for disease and obesity, and parents of pre-school children are in a powerful position to influence diet for life. The technique of thematic synthesis (Thomas & Harden, 2008) was used to synthesise recent qualitative research on parental feeding of pre-school age children (18 months-6 years). The aim was to inform development of nutrition advice by gaining a comprehensive picture of parental feeding behaviours and motivations. Six key parental feeding behaviours were identified: modelling, rewards, pressure and encouragement, repeated exposure, creativity, and limiting intake. Four overarching themes regarding motivations were identified: promoting good health (balance and variety, and weight control); building positive relationships (child involvement, and parental engagement and responsiveness); practicalities and constraints (time, cost, and lack of culinary skill, and pressure and flexibility); and emotional motivations (problem avoidance, and emotional investment). Practicalities and constraints, and emotional motivations impacted more significantly on low income parents. In order to be effective, nutrition advice ought to tap into parents' strong desire to build positive relationships and promote good health while remaining sensitive to the significant constraints and practicalities faced.

    Full Text Available The intellectual development of socioeconomically disadvantaged preschool children is influenced by several factors. The development of intelligence is a multidimensional concept that is determined by biological, social, and environmental factors. In this literature review, however, only the social and environmental factors are discussed. Some of the factors that have profound effect on children's cognitive development are as follows: environmental stimulation, parental attitudes, maternal age, and education. Successful intervention and prevention programs aimed at enhancing children's cognitive development are also exemplified. It appears that early intervention programs in the second and third year of an infant's life have fundamental effects on the cognitive development of disadvan-taged children. It is clear that learning starts with birth. Longitudinal studies revealed that the most effective period for intervention is early childhood. Those who received early day-care and preschool intervention programs have sustained these gains in adolescence and adulthood. Those benefits include higher IQ scores, better achievement test scores, better reading and math skills, more educational attainment, more college degrees, and fewer psychosocial and mental health problems. Therefore, it appears that investing in early high-quality programs provide multiple advantages for individuals and society. Social activists, psychologists, and counsellors should make every effort to affect the allocation of governmental funds and policies.

    CNS-directed therapies for the treatment of leukemia can adversely affect the acquisition of new skills, such as reading/writing and math. Two years after the end of treatments, children show gross and fine motor skill delays that may persist even when patients are considered healed. The goal of the present study was to assess motor skills difficulties in pre-school children with leukemia one year after treatment. Particular attention has been paid to those patients who had undergone Hematopoietic Stem Cell Transplantation (HSCT) and to the relationship between motor delays and age bands. Participants were 60 children (median age of 5; inter quartile range: 3.07-5.76), including 31 females and 29 males, 91.7% of them were affected by acute lymphoblastic leukemia (ALL), and 8.3% by acute myeloid leukemia (AML). Five children had undergone HCST. Parents were interviewed by Vineland Adaptive Behavior Scales (VABS) on children's motor skills and filled in the Italian Temperament Questionnaire (QUIT). VABS's total scores were converted into equivalent mental age scores (EMA). A score difference of at least three months between current age and equivalent mental age was considered a developmental delay. Non-parametric analyses were run to understand if HSCT treatment and a specific age band influence children's motor skills. Significant delays were found in global motor skills (56.7%) as well as in fine and gross motor domains. Mann Whitney U tests showed that children with HSCT were reported to have lower gross motor mean ranks (U = 62; p = 0.004; Mean rank = 15.40) than peers without HSCT (Mean rank = 31.87) and lower mean rank values on motor temperament scale (U = 9; p = 0.003; HSCT Mean rank = 4.75 versus no HSCT Mean rank = 27.81). Kruskal Wallis' tests identified the high risk treatment showing that HSCT experience negatively impacted the motor skills and temperamental motor activity of pre-school children one year after the diagnosis of leukemia.

This modern mindset even penetrates into all areas including in the field of education. If education used to not be considered for girls, today it has now become a need for all people, whether male or female. Not only that, the high levels of education achieved and the image of the selected educational institutions become markers of modern social class society in big cities now, not just in some areas of Surabaya. There are so many early educational institutions in Surabaya and almost all offer best quality education.

    Malnutrition and soil-transmitted helminthic (STH) infection is still a major concern among Orang Asli pre-school children in Malaysia. The objective of this study was to determine the prevalence of malnutrition and STH infection. Besides, this study was also to identify the association between malnutrition and STH. A total of 256 Orang Asli (131 males and 125 females) from Temiar sub-tribes pre-school children aged one to six years from 19 villages in three Orang Asli settlements of Pos Hendrop, Pos Balar and Pos Tohoi located in Gua Musang, Kelantan had participated in this cross-sectional study between September to December 2014. A face-to-face interview was carried out using pre-tested questionnaires on socio-demographic. Children were measured on their body weight and height. The collected stool samples were examined using direct wet smear method for the presence of STH parasite. The results showed the prevalence of underweight and stunting among the children were 45.3% and 76.2% respectively. A total of 161 (62.9%) subjects were positively infected by at least one species of STH. The overall parasite infections were Ascaris lumbricoides (41.0%), Trichuris trichiura (28.5%) and hookworm (2.0%). From the total infected children, 8.6% of them were infected by two species of STH. This research revealed that gender and age group showed statistically significance with stunted with (p=0.003, p=0.049) respectively. Gender and age groups also reported significant association to STH infection among the subjects with (p=0.013, p=0.001) respectively. However, our results indicated that there was no significant association between STH infection with underweight and stunted. Our study reported that the prevalence of malnutrition and STH are still a major concern for the public health and a threat among Orang Asli pre-school children in Kelantan. Immediate action and innovative intervention should be taken by the Government to overcome the problems as these children are the

    Full Text Available Parental co-participation in physical activity (PA may be a beneficial parenting practice for diminishing children’s sedentary time (ST. Less information is available, however, on the explanatory role of co-participation in PA regarding parental educational differences in children's ST. Preschool-aged children (N = 864, mean age 4.8, 52% boys with their parents participated in a cross-sectional DAGIS (Increased Health and Wellbeing in Pre-schools study between years 2015 and 2016. Children (N = 821 wore an accelerometer for one week. Parents were informed of their educational background, and the frequency of visits with their child in nature, to parks or playgrounds, their own yard, and indoor sport facilities (N = 808. Testing the associations required multiple regression analyses. Parents with a low educational background reported more frequent visits with their child to their own yard, and these visits were associated with children’s lower ST. More highly educated parents co-visited indoor sport facilities more frequently, although this did not have a significant association with children’s ST. More frequent visits in nature were associated with a lower ST at weekdays, regardless of educational background. Future health promotion strategies should inform parents that frequent co-participation in PA, for example, in one’s own yard, is beneficial for lowering children’s ST.

    Third-person direct object (DO) clitic pronoun production is examined through an elicited production method in pre-school- and primary school-aged groups of Italian children with specific language impairment (SLI) to establish whether there is an improvement from age 5 years to age 7 years and whether there are qualitative differences in the two groups' responses. It was found that 5- and 7-year-old Italian children with SLI produce fewer third-person DO clitics than same-age peers. The kind of responses they provide changes: at 5 years, children with SLI tend to omit clitics, while at 7 years, they use a full noun. Production of third-person DO clitics is a persistent challenge for children with SLI and is confirmed to be a good clinical marker both at 5 and 7 years of age.

    Full Text Available Social abilities are an essential part of human activity since they have a bearing on self-con­fidence, adoption of roles, self-regulation of behavior and academic performance, among other aspects. This study presents the process of construction and validation of a scale of social abilities for pre-school children. The scale was administered to 318 parents of 3 to 5 years old children of low socio-economic status who attend Primary Health Care Centers in San Miguel de Tucumán, Argentina. Considering the evolutionary and contextual charac­teristics relative to the process of acquisition of social abilities, a different protocol for every age group was designed. The result was a scale with confidence and validity characteristics. The validation of these instruments is helpful for evaluating children in poverty contexts since they enable us to distinguish social resources that allow children’s adaptation.

  6. The use of first language scaffolding to teach English as a foreign language to pre-school children during dramatic play in West Sumatera, Indonesia

    Directory of Open Access Journals (Sweden)

    Mulia Dewi

    2015-01-01

    Full Text Available The Indonesian community generally perceives that English language teaching should require phonology, vocabulary, grammar, discourse, and pragmatics. As a result, this often demands that pre-school teachers use English all the time. Code switching between English, Indonesian, and Minang – the local language of the region – is perceived negatively, and teachers are often criticized for using a multilingual approach that is “part snake and part eel” [sakarek ula sakarek baluik]. This refers to a negative perception of mixing languages in educational settings. In fact, code switching between Minang (first language, Indonesian (second language, and English (foreign language is the norm of language use in this part of Indonesia. However, in this community, there is a lack of respect for pre-school teachers' professionalism as well as scepticism towards the effectiveness of a multilingual teaching approach, which is used widely at the pre-school level. Vygotsky [14], the Russian psychologist, presents a different perspective on this phenomenon, noting that children learn languages by playing. Their first language can be the main tool to help them understand new words and utterances in context. By using code switching, teachers help pre-school children to link their prior knowledge and experience to the new forms of expression that enable them to derive the meaning of new words from the social context of language use. For this reason, scaffolding techniques should be used by pre-school teachers, particularly in ways which support children's cognitive development in constructing new meanings based on their first language experience. This paper, based on a research study-in-progress at Deakin University, Melbourne, Australia, explores patterns of interaction between pre-school teachers and their students as teachers scaffold the development of EFL through dramatic play in West Sumatera, Indonesia. This interaction is systemic in nature and

  8. Analysis of Understanding the Concept of Buoyancy in the Context of its Transfer from Pre-school Teachers to Children

    Directory of Open Access Journals (Sweden)

    Petra Furlan

    2014-03-01

    Full Text Available Kindergarten curricula (Bahovec et al. 1999, 37 cover different areas of education that are sensibly interconnected and integrated. Science is one of the areas that represent child’s first learning about the surrounding world and the first introduction to nature. Science education is a very suitable approach of introducing children into basic research work, since in nature objects and phenomena are more concrete, and hence the children are instinctively attracted. Therefore, science education could act as a starting point for all other areas of education. Teaching science comprises several difficulties, which are mainly connected with the way how contents are introduced to children. This is often a great challenge and great responsibility for pre-school teachers, because the scientific content needs to be explained in an appropriate way taking into consideration the child's age, the use of correct terminology, and at the same time avoiding inadequate generalization and over-simplification. Buoyancy is a natural phenomenon that is experienced by every child, but which, on the other hand, is quite difficult to explain. With the present study we wished to assess the knowledge considering buoyancy of the part-time students within the Pre-school Teaching educational programme at the Faculty of Education of the University of Primorska, which is performed on different locations throughout Slovenia. These students already teach in the kindergartens and should be well acquainted with buoyancy from previously passed physics courses at the Faculty of Education. We examined how they explained the buoyancy to children in kindergartens, and whether the knowledge about buoyancy is affected by their working experience or the location of their study. The results show that the students’ knowledge about buoyancy is insufficient and incomplete. In addition, many misconceptions about buoyancy are transmitted to the children in the process of teaching

Telephone interviews with mothers. Online survey of ECE managers/head teachers. New Zealand. Children (n 1181) aged 45 months in the Growing Up in New Zealand longitudinal study. A mean 5·3 of 8 RNB were followed at home, with statistical differences by gender and ethnic group, but not socio-economic position. ECE services followed a mean 4·8 of 8 RNB, with differences by type of service and health-promotion programme participation. No congruence between adherence at home and in ECE services was found; half of children with high adherence at home attended a service with low adherence. A greater proportion of children in deprived communities attended a service with high adherence, compared with children living in the least deprived communities (20 and 12 %, respectively). Children, across all socio-economic positions, may not experience RNB at home. ECE settings provide an opportunity to improve or support behaviours learned at home. Targeting of health-promotion programmes in high-deprivation areas has resulted in higher adherence to RNB at these ECE services. The lack of congruence between home and ECE behaviours suggests health-promotion messages may not be effectively communicated to parents/family. Greater support is required across the ECE sector to adhere to RNB and promote wider change that can reach into homes.

    1996-01-01

    For nuclear power plants, it is required to ensure the safety under the high reliability and to attain the high rate of operation. In the manufacture and installation of the machinery and equipment, the welding techniques which become the basis exert large influence to them. For the purpose of improving joint performance and excluding human errors, welding heat input and the number of passes have been reduced, the automation of welding has been advanced, and at present, narrow gap arc welding and high energy density welding such as electron beam welding and laser welding have been put to practical use. Also in the welding of pipings, automatic gas metal arc welding is employed. As for the welding of main machinery and equipment, there are the welding of the joints that constitute pressure boundaries, the build-up welding on the internal surfaces of pressure vessels for separating primary water from them, and the sealing welding of heating tubes and tube plates in steam generators. These weldings are explained. The welding of pipings and the state of development and application of new welding methods are reported. (K.I.)

  3. Assessment of the content of mercury, methylmercury and other elements of interest in fish, hair and diets of pre-school children of the Amazon region

    2006-01-01

    Studies show that some regions of the Amazon region suffer mercury (Hg) impacts as a direct result of both natural and anthropogenic processes. Jau National Park (PNJ) is the only National Park in Brazil that protects an entire black water basin (Jau River), flood land and tropical reserve. These conditions favor Hg methylation in the aquatic biota. This in turn, exposes living on the river populations to Hg contamination as well as the adjacent regions. Preliminary studies of pre-school children diets from PNJ communities have shown that these diets have a worrisome high Hg content. The present study assessed total Hg content, micro nutrients (Ca, Fe, K, Na, Se and Zn) and macro nutrients (proteins, lipids, ash, energy, carbohydrate) in pre-school diets in the PNJ and surrounding communities. Furthermore, total and Me Hg levels were also determined in hair samples of these children as well as those living in several neighborhoods of the city of Manaus. Included in this determination were the fish most consumed by these populations. From these results it was possible to evaluate the nutritional content of the diets and the exposure of the children to Hg and Se Hg. Cold vapor atomic absorption spectrometry was used to quantify total and Me Hg. Micro nutrient determination was performed using neutron activation analysis technique (NAA) and Macro nutrient through AOAC methodologies (USA). All analytical methods were developed and validated for precision and accuracy by means of reference materials analyses with certified values for the determined elements. Furthermore, the uncertainty sources for Hg and Me Hg determination were assessed and the expanded uncertainties were calculated. Total Hg levels in diets and total and Me Hg levels for hair samples, were well above those values found in different localities of the Amazon region. This also holds true for those surrounding areas of the JNP. For many children Hg intake values passed the 5 mug Hg/body weigh/week (PTWI

    2011-07-01

    Maternal employment has been shown to be associated with childhood overweight and obesity (Ow/Ob), but the presence of family members who care for children in place of the mothers might influence children's Ow/Ob and lifestyles. The influence of maternal employment on children's Ow/Ob should be examined together with the presence of caregivers such as grandparents. The effects of maternal employment and the presence of grandparents on lifestyles and Ow/Ob in Japanese pre-school children were investigated. Cross-sectional study on 2114 children aged 3-6 years who attended all childcare facilities in a city and primary caregivers was conducted. Children's weight and height, family environments (family members, maternal employment, single parent, number of siblings and parental Ow/Ob) and lifestyles (dietary, physical activity and sleeping habits) were surveyed using a self-administered questionnaire. Ow/Ob was defined by the International Obesity Task Force cut-offs. The eligible participants were 1765 children. The prevalence of Ow/Ob was 8.4% in boys and 9.9% in girls. Maternal employment was associated positively with irregular mealtimes, unfixed snacking times, bedtime after 10 p.m. and nighttime sleep duration of less than 10 h, whereas three-generation families were associated negatively with irregular mealtimes after adjustment for children's characteristics and family environments. Irregular mealtimes (OR (95% CI); 2.03 (1.36, 3.06)) and nighttime sleep duration of less than 10 h (1.96 (1.28, 3.01)) were associated with increased risks of being Ow/Ob. Both maternal employment and three-generation families were significantly associated with children's Ow/Ob. However, three-generation families maintained a significant association (1.59 (1.08, 2.35)) after adjustment for maternal employment. These study results suggest that the grandparents who care for pre-school children in place of mothers are more likely to contribute to childhood Ow/Ob than maternal

    Full Text Available Introduction: Experimental data in preschool aged children proves the determining role of the auditory and visual processes for future reading skills, therefore the investigation of complex forms of visual perception in this age period is diagnostically important. Objectives: Basic aim of the research is assessment of the sensitive period for the non-verbal perceptive operations in pre-school aged children, and determination of subgroup with low results for non-verbal perception. Methods: The dynamics of the visual per-ception (visual gnosis in typically develop¬ing children were tested with an adapted version of the Poppelreuter-Ghent Test for figure-ground segregation. The total number of overlapping objects is 33, grouped accor¬ding to the level of difficulty. The children are given a group of objects separately in a following sequence and they should segregate and name the objects. Results: A number of 365 typically developing children without diagnosis of visual disorders and without corrected visus took part in the research. All children, aged 4, 5, and 6 from three different settlements attend state nursery schools and have Bulgarian as a mother tongue. A three-factor dispersion analysis was held to define the statistical significance of the independent factors age, gender and settlement. The research’s data define the 5 year olds as sensitive about the dynamics of the complex forms of visual perception, compared to the four year old children (p

  6. Concrete Waste Recycling Process for High Quality Aggregate

    2008-01-01

    Large amount of concrete waste generates during nuclear power plant (NPP) dismantling. Non-contaminated concrete waste is assumed to be disposed in a landfill site, but that will not be the solution especially in the future, because of decreasing tendency of the site availability and natural resources. Concerning concrete recycling, demand for roadbeds and backfill tends to be less than the amount of dismantled concrete generated in a single rural site, and conventional recycled aggregate is limited of its use to non-structural concrete, because of its inferior quality to ordinary natural aggregate. Therefore, it is vital to develop high quality recycled aggregate for general uses of dismantled concrete. If recycled aggregate is available for high structural concrete, the dismantling concrete is recyclable as aggregate for industry including nuclear field. Authors developed techniques on high quality aggregate reclamation for large amount of concrete generated during NPP decommissioning. Concrete of NPP buildings has good features for recycling aggregate; large quantity of high quality aggregate from same origin, record keeping of the aggregate origin, and little impurities in dismantled concrete such as wood and plastics. The target of recycled aggregate in this development is to meet the quality criteria for NPP concrete as prescribed in JASS 5N 'Specification for Nuclear Power Facility Reinforced Concrete' and JASS 5 'Specification for Reinforced Concrete Work'. The target of recycled aggregate concrete is to be comparable performance with ordinary aggregate concrete. The high quality recycled aggregate production techniques are assumed to apply for recycling for large amount of non-contaminated concrete. These techniques can also be applied for slightly contaminated concrete dismantled from radiological control area (RCA), together with free release survey. In conclusion: a technology on dismantled concrete recycling for high quality aggregate was developed

    Reproducible high-T c Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge (1 to 5 μm wide) is firstly designed by ion irradiating a c-axis-oriented YBa 2 Cu 3 O 7-δ film through a gold mask such as the nonprotected part becomes insulating. A lower T c part is then defined within the bridge by irradiating with a much lower fluence through a narrow slit (20 nm) opened in a standard electronic photoresist. These planar junctions, whose settings can be finely tuned, exhibit reproducible and nearly ideal Josephson characteristics. This process can be used to produce complex Josephson circuits

    2016-06-01

    Cardiopulmonary resuscitation (CPR) represents the cornerstone of cardiac arrest resuscitation care. Prompt delivery of high-quality CPR can dramatically improve survival outcomes; however, the definitions of optimal CPR have evolved over several decades. The present review will discuss the metrics of CPR delivery, and the evidence supporting the importance of CPR quality to improve clinical outcomes. The introduction of new technologies to quantify metrics of CPR delivery has yielded important insights into CPR quality. Investigations using CPR recording devices have allowed the assessment of specific CPR performance parameters and their relative importance regarding return of spontaneous circulation and survival to hospital discharge. Additional work has suggested new opportunities to measure physiologic markers during CPR and potentially tailor CPR delivery to patient requirements. Through recent laboratory and clinical investigations, a more evidence-based definition of high-quality CPR continues to emerge. Exciting opportunities now exist to study quantitative metrics of CPR and potentially guide resuscitation care in a goal-directed fashion. Concepts of high-quality CPR have also informed new approaches to training and quality improvement efforts for cardiac arrest care.

  14. Effects of maternal gate-keeping behavior on father involvement in care of a pre-school child

    2010-01-01

    Full Text Available The research so far indicates that the context in which the father’s role takes place significantly influences the form and level of father involvement in taking care of the child. The primary goal of this research was to describe the forms and effects of maternal gate-keeping behavior as a characteristic form of interaction between parents which is, as part of the context, considered a significant factor in father involvement in care of the child. Research participants were 247 parental couples from complete families whose oldest child attended a pre-school institution. Fathers provided assessments of their own involvement via the Father Involvement Inventory, as well as assessments of prominence of gate-keeping behavior in their wives via the checklist of maternal gate-keeping behavior. Mothers reported on their beliefs about the importance and possibilities of father involvement in care of the child, as well as on their personal satisfaction with the current involvement of their husband in the joint care of the child. The results point out to the particular forms of mothers’ ambivalence when it comes to the joint care of the child, which is a form of gate-keeping behavior. The frequency of gate-keeping behavior, assessed by the checklist, significantly changes the possibilities of father involvement in taking care of the child in the developmental phase of the family, having in mind that the task of this phase is precisely the definition of parental roles and formation of parent cooperative principle.

    BackgroundMaternal pre-pregnancy obesity may impair infant neuropsychological development, but it is unclear whether intrauterine or confounding factors drive this association.MethodsWe assessed whether maternal pre-pregnancy obesity was associated with neuropsychological development in 1,827 Spanish children. At 5 years, cognitive and psychomotor development was assessed using McCarthy Scales of Children's Abilities, attention deficit hyperactivity disorder (ADHD) symptoms using the Criteria of Diagnostic and Statistical Manual of Mental Disorders, and autism spectrum disorder symptoms using the Childhood Asperger Syndrome Test. Models were adjusted for sociodemographic factors and maternal intelligence quotient. We used paternal obesity as negative control exposure as it involves the same source of confounding than maternal obesity.ResultsThe percentage of obese mothers and fathers was 8% and 12%, respectively. In unadjusted models, children of obese mothers had lower scores than children of normal weight mothers in all McCarthy subscales. After adjustment, only the verbal subscale remained statistically significantly reduced (β: -2.8; 95% confidence interval: -5.3, -0.2). No associations were observed among obese fathers. Maternal and paternal obesity were associated with an increase in ADHD-related symptoms. Parental obesity was not associated with autism symptoms.ConclusionMaternal pre-pregnancy obesity was associated with a reduction in offspring verbal scores at pre-school age.

    The growing concern about poor dietary practices among low-income families has led to a 'victim blaming' culture that excludes wider social and environmental factors, which influence household food choices. This small-scale qualitative study investigated influences on the diets of young children in families on a low income in the West Midlands, UK. Using semi-structured interview schedule, rich data was gathered through individual interviews with 11 mothers of pre-school children. Information was collected about the type and range of food given following the introduction of solid foods including factors influencing parent's knowledge and diet, sources of nutrition advice and financial constraints. Food accessibility and storage issues were also explored. Interviews were audio-recorded, transcribed and analysed using a modified grounded theory approach. Findings highlighted that parents and professionals may have different interpretations about 'cooking from scratch'. The results indicated that some parents have poor understanding of what constitutes a healthy diet. However, most parents included fruit and vegetables to varying degrees and were motivated to give their children healthy foods, suggesting that, with adequate support and information, the diets of these children could be improved. There was evidence that when striving to improve the diet of their children, many parents' diets also improved. The findings from this small-scale in-depth study highlighted a number of issues for local and national policy and practice in the area of nutrition and child health in the early years. © 2013 John Wiley & Sons Ltd.

    A number of studies have shown that teachers are capable of recognising pupils with language difficulties if they have suitable guidelines or guidance. To determine the effectiveness of an observation-based protocol for pre-school education teachers in the detection of phonetic-phonological, semantic and morphosyntactic difficulties. The sample consisted of 175 children from public and state-subsidised schools in Valencia and its surrounding province, together with their teachers. The children were aged between 3 years and 6 months and 5 years and 11 months. The protocol that was used asks for information about pronunciation skills (intelligibility, articulation), conversational skills (with adults, with peers), literal understanding of sentences, grammatical precision, expression through discourse, lexical knowledge and semantics. There was a significant correlation between the teachers' observations and the criterion scores on intelligibility, literal understanding of sentences, grammatical expression and lexical richness, but not in the observations concerning articulation and verbal reasoning, which were more difficult for the teachers to judge. In general, the observation protocol proved to be effective, it guided the teachers in their observations and it asked them suitable questions about linguistic data that were relevant to the determination of difficulties in language development. The use of this protocol can be an effective strategy for collecting information for use by speech therapists and school psychologists in the early detection of children with language development problems.

    Full Text Available An understanding of predictors of family needs for the families of preschool children with cerebral palsy (CP is important for provision of efficient and cost-effective services. The aim of this study was to identify the characteristics of children, families and services that are risk factors to meeting family needs for community and financial resources. 234 parents of pre-school children with CP completed a modified version of the Family Needs Survey (FNS, the Measure of Processes of Care (MPOC-20, and a demographic questionnaire. The gross motor function level and communication function level of children were classified on the basis of the Gross Motor Function Classification System (GMFCS and the Communication Function Classification System (CFCS respectively. Two hierarchical multiple regression models were generated to determine the predictors of unmet family needs. The socialisation and communication skills of children, as well as caregiver employment and family income levels were significant predictors of family needs for community resources (adjusted R2=0.44. Significant risk factors in terms of family needs for financial resources included the child's gross motor limitations, caregiver employment, low levels of family income and no ability to receive services on the basis of enabling and partnership principles (adjusted R2=0.51. A child's limitations in terms of communication, gross motor functions and socialisation, as well as the socioeconomic status of the child's family, must be taken into account when planning services for families with preschool children with CP.

    To determine the dental caries experience and treatment needs among 5-year-olds in Albania. This cross sectional study was conducted in 2015 by using a cluster sampling technique. The dmft was used to assess dental caries experience and caries prevalence as percentages of children with dmf⟩0. Caries treatment needs were assessed with dt/dmft x 100, missing teeth with mt/dmft x 100 and ft /dmft x 100 as the Care Index. 2,039 five-year-olds, from 17 districts of Albania were selected . Children's residency was divided into 3 main regions (South, West, Central and North). WHO 2013 diagnostic criteria were used and dental caries was recorded at cavity level d3. The mean age was 5.4 (SD 0.5) years. The caries prevalence (dmf⟩0) was 84.1%. The prevalence of children without cavitated lesions (d=0) was 20.1%. The mean dmft index was 4.41 (SD 3.83). The caries treatment needs were 84% (SD 26%). The Albanian 5-year-olds assessed in this survey had a high dental caries experience and untreated cavities in the primary dentition. The national health authorities should introduce preventive programs and improved dental care access for this age group. Copyright© 2017 Dennis Barber Ltd

    Determining the relationship between vocal habits and environmental/ occupational conditions with the presence of vocal disturbance (dysphonia) in teachers and functionaries working at community-based, initial childhood education centres (kindergartens). This was a descriptive study which adopted across-sectional approach using 198 participants which was developed in three phases. Phase 1: consisted of identifying participants having the highest risk of presenting vocal disturbance. Phase 2consisted of observation-analysis concerning the voice use and vocal habits of participants who had been identified in phase 1. Phase 3consisted of perceptual and computational assessment of participants' voices using Wilson's vocal profile and the multidimensional voice program. Individuals having pitch breaks, throat clearing, increased voice intensity, and gastro-oesophageal reflux were found to present below standard fundamental frequency (FF). Subjects having altered breathing and increased voice intensity were identified as having above standard shimmer and jitter acoustic values. A high rate of inability to work was found due to vocal disturbance. It is thus suggested that there is a correlation between vocal habits and vocal disorders presented by preschool teachers in kindergarten settings.

    Full Text Available Abstract Background We evaluated growth and nutritional status of preschool children between 2 and 6 years old from low income families from 14 daycare centers. Methods Cross-sectional study with 1544 children from daycare centers of Santo Andre, Brazil. Body weight (W, height (H and body mass index (BMI were classified according to the 2000 National Center for Health Statistics (CDC/NCHS. Cutoff points for nutritional disorders: -2 z scores and 2.5 and 10 percentiles for malnutrition risk, 85 to 95 percentile for overweight and above BMI 95 percentile for obesity. Stepwise Forward Regression method was used including age, gender, birth weight, breastfeeding duration, age of mother at birth and period of time they attended the daycare center. Results Children presented mean z scores of H, W and BMI above the median of the CDC/NCHS reference. Girls were taller and heavier than boys, while we observed similar BMI between both genders. The z scores tended to rise with age. A Pearson Coefficient of Correlation of 0.89 for W, 0.93 for H and 0.95 for BMI was documented indicating positive association of age with weight, height and BMI. The frequency of children below -2 z scores was lower than expected: 1.5% for W, 1.75% for H and 0% for BMI, which suggests that there were no malnourished children. The other extremity of the distribution evidenced prevalence of overweight and obesity of 16.8% and 10.8%, respectively. Conclusion Low income preschool children are in an advanced stage of nutritional transition with a high prevalence of overweight.

The aims of this study were to compare: (i) energy intake (EI) obtained using KidMeal-Q to total energy expenditure (TEE) measured via doubly labelled water and (ii) the intake of certain foods measured using KidMeal-Q to intakes acquired by means of 24 h dietary recalls in 38 children aged 5.5 years. The mean EI calculated using KidMeal-Q was statistically different ( p food frequency questionnaires. However, its accuracy needs to be improved before it can be used in studies in pre-school children.

    Full Text Available This study aims to investigate whether the epistemological beliefs, creativity levels and thinking styles of pre-school teachers are significant predictors of their problem solving skills and in accordance with this purpose, a correlational survey design was used. The sample of this study consists of 155 pre school teachers working in Isparta in the school year 2011-2012. As data collection tools, “Problem Solving Inventory”, “Epistemological Beliefs Scale, “How Creative Are You?” and lastly, “Thinking Styles Inventory” were used. Data were analyzed by stepwise multiple regression analysis. In this study, it has been found that problem solving skills of the teachers are a significant predictor of preschool teachers’ perceptions of their creativity levels positively and perceptions of their conventional thinking styles negatively in the belief that learning depends on ability.

    An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

    The present paper examines the relationship between social factors, food consumption during television viewing, and overall television viewing and how these are associated with BMI when the role of familial and social factors are considered in a population-based birth cohort of pre-school children from Québec (Canada). The analyses were performed using data from the Longitudinal Study of Child Development in Québec (1998-2002) (LSCDQ). The study follows a representative sample (n 2103) of children born in 1998 in the Canadian province of Québec. A nutrition assessment was conducted on 1549 children aged 4.5 years and included a 24 h dietary recall, an eating behaviour and television viewing questionnaire, and a measurement of children's heights and weights. Statistical analyses were performed. Nearly one-quarter of children ate at least twice daily in front of the television. Children who consumed snacks while watching television on a daily basis had higher BMI than children who did so less frequently. Children who ate snacks in front of the television every day, or some times during the week, ate more carbohydrates (total), more fat and less protein, fewer fruits and vegetables, and drank soft drinks more often than children who never ate snacks in front of the television. Health professionals should target parents of children at risk of overweight/obesity with focused strategies to help children change the types of foods consumed during television viewing and to reduce the time spent watching television, particularly during meal times, which may change children's dietary intake and eating patterns.

    Research on adult populations has widely investigated the deep differences that characterize individuals who embrace either conservative or liberal views of the world. More recently, research has started to investigate these differences at very early stages of life. One major goal is to explore how parental political ideology may influence children's characteristics that are known to be associated to different ideological positions. In the present work, we further investigate the relations between parents' ideology and children cognitive processing strategies within the framework of political ideology as motivated social cognition (Jost et al., 2003) and the dual process model of political ideology (Duckitt et al., 2002). Specifically, epistemic (implicit attitudes toward order vs. chaos), existential (negativity and threat bias), and relational needs (conformity measure) were assessed in pre-school children (N = 106; 4–6 years). For each child at least one parent completed both the Social Dominance Orientation (SDO) and the Right Wing Authoritarianism (RWA) measures. Interestingly, results indicated that mothers' and fathers' responses had unique associations with children's socio-cognitive motivations, and different findings emerged in relation to the two facets of parental authoritarianism, namely dominance (i.e., SDO) and submission (i.e., RWA). More specifically, children's existential needs appeared to be more related to mothers' RWA scores, whereas children's epistemic needs appeared to be more related to fathers' SDO. Finally, parents' RWA and SDO scores appeared to have opposite effects on children's relational needs: children's conformity increased at increasing levels of mothers' RWA and decreased at increasing levels of fathers' SDO. Overall, however, results were relatively weak and several links between the responses of parents and their children were not significant, suggesting caution in drawing strong conclusions about the impact of parents

    To determine the characteristics influencing pneumococcal serotype colonization in healthy pre-school aged children, the distribution of serotypes and their antimicrobial susceptibility, after the introduction of pneumococcal 7-valent conjugate vaccine (VNC-7 v). SUJETOS AND METHODS: Nasopharyngeal samples were collected from children under 6 years of age attending well-child examinations in the province of Zaragoza (Spain). Logistic regression was used to study different variables related to the status of the carriers. Of the 371 children studied 30.7% were found to be carriers. With a vaccine coverage rate of 66%, factors related with presence of pneumococcal carriage were found to be the number of siblings (OR 1.44; CI 95% 1.05-1.97 for each sibling), attending a school or child day care centre (OR 3.99; CI 95% 2.00-7.96) and suffering from a minor upper respiratory tract infection (URTI) (OR 1.72; CI 95% 1.02-2.90). Only 8.7% corresponded to VNC-7 v serotypes. The most common non VNC-7 v serotypes isolated were 19A, 6A, 15B, 11, and 15A. Significantly greater resistance was detected among VNC-7 v serotypes. Children in the setting of this study carried pneumococci more commonly when they have siblings, attend school or day care, or suffer from minor URTI. In the VNC-7 v vaccine era, VNC-7 v serotypes have become rare occurrences (8.7%) and emerging serotypes present better susceptibility to antibiotics. Copyright © 2010 Elsevier España, S.L.

    Sleeping and studying are the day-to-day activities of a teenager attending school. To determine the quality of sleep and its relationship to the academic performance among students attending morning and afternoon shifts in a public high school. Students of the first and second year of high school answered an interview about socio-demographic background, academic performance, student activities and subjective sleep quality; they were evaluated using the Pittsburgh Sleep Quality Index (PSQI). The interview was answered by 322 first year students aged 15 ± 5 years attending the morning shift and 364 second year students, aged 16 ± 0.5 years, attending the afternoon shift. The components: sleep latency, habitual sleep efficiency, sleep disturbance, drug use and daytime dysfunction were similar and classified as good in both school shifts. The components subjective sleep quality and duration of sleep had higher scores among students of the morning shift. The mean grades during the first semester of the students attending morning and afternoon shifts were 5.9 and 5.8, respectively (of a scale from 1 to 7). Among students of both shifts, the PSQI scale was associated inversely and significantly with academic performance. A bad sleep quality influences academic performance in these students.

    Social, emotional and behavioural development in early to middle childhood impact upon many outcomes in future life and are influenced by home, neighbourhood and school environments. We used linked data to investigate differences between areas in Glasgow City in level of difficulties in pre-school age children, after consideration of demographics, including area-level deprivation. Pre-school education staff completed Strengths and Difficulties Questionnaires (SDQ) on all children progressing to school from a local authority or partnership (local authority-funded private) pre-school in Glasgow City between 2010 and 2012. These data were linked to individual (age, gender) and area-level (deprivation) demographics from the City Council Education Services Department. Statistical models were fitted to the SDQ scores, adjusting for age, gender, area deprivation, year of school entry, pre-school establishment attended and electoral ward of residence. Correlation between neighbouring wards was incorporated to allow for clustering of scores. Boys and those living in more deprived areas had higher levels of difficulties. Children aged 5.0-5.5 years had fewest difficulties, while the oldest and youngest children had similar levels of difficulties. There were no significant secular trends by year of school entry. There remained differences among areas after adjusting for these variables, with children living in some areas having fewer difficulties than would be expected based on their socio-demographic characteristics. There remained differences in children's levels of difficulties between areas after adjusting for age, gender, area deprivation and year of school entry. Children in some very deprived areas had fewer difficulties than might be expected, while those in relatively affluent areas had more difficulties than expected based on their deprivation level. There may be other, unmeasured, individual- and area-level reasons for children's level of difficulties, and these

    Miranda, Rommel Joseph

    By employing qualitative methods, this study sought to determine the perceptions that urban stakeholders hold about what characteristics should distinguish a high school science teacher whom they would consider to demonstrate high quality in science teaching. A maximum variation sample of six science teachers, three school administrators, six parents and six students from a large urban public school district were interviewed using semi-structured, in-depth interview techniques. From these data, a list of observable characteristics which urban stakeholders hold as evidence of high quality in science teaching was generated. Observational techniques were utilized to determine the extent to which six urban high school science teachers, who meet the NCLB Act criteria for being "highly qualified", actually possessed the characteristics which these stakeholders hold as evidence of high quality in science teaching. Constant comparative analysis was used to analyze the data set. The findings suggest that urban stakeholders perceive that a high school science teacher who demonstrates high quality in science teaching should be knowledgeable about their subject matter, their student population, and should be resourceful; should possess an academic background in science and professional experience in science teaching; should exhibit professionalism, a passion for science and teaching, and a dedication to teaching and student learning; should be skillful in planning and preparing science lessons and in organizing the classroom, in presenting the subject matter to students, in conducting a variety of hands-on activities, and in managing a classroom; and should assess whether students complete class goals and objectives, and provide feedback about grades for students promptly. The findings further reveal that some of the urban high school science teachers who were deemed to be "highly qualified", as defined by the NCLB Act, engaged in practices that threatened quality in science

  3. High quality digital holographic reconstruction on analog film

    High quality real-time digital holographic reconstruction, i.e. at 30 Hz frame rates, has been at the forefront of research and has been hailed as the holy grail of display systems. While these efforts have produced a fascinating array of computer algorithms and technology, many applications of reconstructing high quality digital holograms do not require such high frame rates. In fact, applications such as 3D holographic lithography even require a stationary mask. Typical devices used for digital hologram reconstruction are based on spatial-light-modulator technology and this technology is great for reconstructing arbitrary holograms on the fly; however, it lacks the high spatial resolution achievable by its analog counterpart, holographic film. Analog holographic film is therefore the method of choice for reconstructing highquality static holograms. The challenge lies in taking a static, high-quality digitally calculated hologram and effectively writing it to holographic film. We have developed a theoretical system based on a tunable phase plate, an intensity adjustable high-coherence laser and a slip-stick based piezo rotation stage to effectively produce a digitally calculated hologram on analog film. The configuration reproduces the individual components, both the amplitude and phase, of the hologram in the Fourier domain. These Fourier components are then individually written on the holographic film after interfering with a reference beam. The system is analogous to writing angularly multiplexed plane waves with individual component phase control.

    2013-01-01

    Full Text Available Aim: to study defects of infants and pre-school children diet, which negative consequences are aggravated by unfavorable nature and ecological conditions of St. Petersburg region. Patients and methods: diet of 119 children (53 — aged from 2 to 3 years old and 66 — from 4 to 6 years old visiting St. Petersburg pre-school institutions of 12-hours stay (including all additional food outside the institution was analyzed.  Analysis of diet was formed by assessment of actual nutrition and supply of nutrients. Results: actual diet of infants and pre-school children was found to deviate significantly from recommended standards which lead to long-standing imbalance of the main nutrients intake. Many defects of the diet are maintained by specific negative factors of the habitat. Combined influence of such influence causes disturbances in development and increase of ecology-dependent disorders in children. Conclusions: in organization of nutrition of children living in unfavorable nature and ecology conditions account must be taken not only of age standards of nutrients and calories intake, but weather, nature biological rhythms and specific geological characteristics.

    The aim of this study was to explore the effect of single-dose albendazole and vitamin A intervention on the anaemic status and Fe metabolism of pre-school children. This study was a randomised, placebo-controlled and double-blinded intervention trial. All eligible anaemic pre-school children were randomly divided into three groups: group 1 received no intervention, which served as the control group, group 2 received 400 mg single-dose albendazole administration and group 3 received a 60000 μg vitamin A capsule combined with 400 mg single-dose albendazole at the beginning of the study. The follow-up period was for 6 months. Anthropometry and biochemical index about Fe metabolism were measured before and after intervention. A total of 209 pre-school anaemic children were randomly divided into three intervention groups (sixty-four, sixty-two and sixty for groups 1, 2 and 3, respectively). The mean age of the children in the study was 4·4 (sd 0·7) years and 50·5 % of the children were female (94/186). After a follow-up period of 6 months, the levels of serum retinol, ferritin, transferrin receptor-ferritin index and body total Fe content of children in group 3 were significantly higher compared with children in groups 1 and 2 (PAlbendazole plus vitamin A administration showed more efficacy on the improvement of serum retinol and Fe metabolic status.

    High-quality quantum-state and entanglement transfer can be achieved in an unmodulated spin bus operating in the ballistic regime, which occurs when the endpoint qubits A and B are nonperturbatively coupled to the chain by a suitable exchange interaction j 0 . Indeed, the transition amplitude characterizing the transfer quality exhibits a maximum for a finite optimal value j opt 0 (N), where N is the channel length. We show that j opt 0 (N) scales as N -1/6 for large N and that it ensures a high-quality entanglement transfer even in the limit of arbitrarily long channels, almost independently of the channel initialization. For instance, for any chain length the average quantum-state transmission fidelity exceeds 90% and decreases very little in a broad neighbourhood of j opt 0 (N). We emphasize that, taking the reverse point of view, should j 0 be experimentally constrained, high-quality transfer can still be obtained by adjusting the channel length to its optimal value.

  11. Quality and efficiency in high dimensional Nearest neighbor search

    KAUST Repository

    Tao, Yufei; Yi, Ke; Sheng, Cheng; Kalnis, Panos

    2009-01-01

    Nearest neighbor (NN) search in high dimensional space is an important problem in many applications. Ideally, a practical solution (i) should be implementable in a relational database, and (ii) its query cost should grow sub-linearly with the dataset size, regardless of the data and query distributions. Despite the bulk of NN literature, no solution fulfills both requirements, except locality sensitive hashing (LSH). The existing LSH implementations are either rigorous or adhoc. Rigorous-LSH ensures good quality of query results, but requires expensive space and query cost. Although adhoc-LSH is more efficient, it abandons quality control, i.e., the neighbor it outputs can be arbitrarily bad. As a result, currently no method is able to ensure both quality and efficiency simultaneously in practice. Motivated by this, we propose a new access method called the locality sensitive B-tree (LSB-tree) that enables fast highdimensional NN search with excellent quality. The combination of several LSB-trees leads to a structure called the LSB-forest that ensures the same result quality as rigorous-LSH, but reduces its space and query cost dramatically. The LSB-forest also outperforms adhoc-LSH, even though the latter has no quality guarantee. Besides its appealing theoretical properties, the LSB-tree itself also serves as an effective index that consumes linear space, and supports efficient updates. Our extensive experiments confirm that the LSB-tree is faster than (i) the state of the art of exact NN search by two orders of magnitude, and (ii) the best (linear-space) method of approximate retrieval by an order of magnitude, and at the same time, returns neighbors with much better quality. © 2009 ACM.

    This paper reports on a high quality flux control system for electron gun evaporation developed and tested for the MBE growth of high temperature superconductors. The system can be applied to any electron gun without altering the electron gun itself. Essential elements of the system are a high bandwidth mass spectrometer, control electronics and a high voltage modulator to sweep the electron beam over the melt at high frequencies. the sweep amplitude of the electron beam is used to control the evaporation flux at high frequencies. The feedback loop of the system has a bandwidth of over 100 Hz, which makes it possible to grow superlattices and layered structures in a fast and precisely controlled manner

    School-based interventions involving teacher and/or child training have been shown to benefit teacher practices and to prevent conduct problems and improve children's social and emotional competence in developed countries; however, we are aware of no reports from a developing country. We conducted a pilot study of the Incredible Years Teacher Training programme and a curriculum unit on social and emotional skills based on concepts and activities drawn from the Incredible Years Dina Dinosaur Classroom Curriculum to determine if this approach is appropriate for use with Jamaican pre-school teachers and children. Five pre-schools in Kingston, Jamaica were randomly assigned to an intervention (3 pre-schools with 15 classrooms) or control (2 pre-schools with 12 classrooms) condition. Intervention involved seven whole-day teacher workshops using the Incredible Years Teacher Training programme supplemented by 14 child lessons in each class. The project was evaluated through structured observations of four categories of teacher behaviour and four observer ratings: two rating scales of child behaviour and two rating scales of classroom atmosphere. Significant intervention benefits were found to teachers' behaviour with increased positive behaviour [b = 7.9; 95% confidence interval (CI): 3.5, 12.3], reduced negative behaviour (b =-3.5; 95% CI: -6.6, -0.2) and increases in the extent to which teachers promoted children's social and emotional skills (b = 46.4; 95% CI: 11.0, 81.7). The number of teacher commands was not significantly reduced (b =-2.71; 95% CI: -6.01, 0.59). Significant intervention benefits were found to ratings of child behaviour with an increase in children's appropriate behaviour (b = 5.7, 95% CI: 1.0, 10.8) and in children's interest and enthusiasm (b = 7.2, 95% CI: 0.9, 13.5). Intervention also benefited classroom atmosphere with increases in opportunities provided for children to share and help each other (b = 1.3, 95% CI: 0.5, 2.1) and in teacher warmth

    The High Flux Reactor (HFR) is one high power multi-purpose materials testing research reactor of the tank-in-pool type, cooled and moderated by light-water. It is operated at 45 MW at a prescribed schedule of 11 cycles per year, each comprising 25 operation days and three shut-down days. Since the licence for the operation of HFR was granted in 1962, a total of 14 amendments to the original licence have been made following different modifications in the installations. In the meantime, international nuclear standards were developed, especially in the framework of the NUSS programme of the IAEA, which were adopted by the Dutch Licensing Authorities. In order to implement the new standards, the situation at the HFR was comprehensively reviewed in the course of an audit performed by the Dutch Licensing Authorities in 1988. This also resulted in formulating the task of setting-up an 'HFR - Integral Quality Assurance Handbook' (HFR-IQAD) involving both organizations JRCIAM and ECN, which had the unique framework and basic guideline to assure the safe and efficient operation and exploitation of the HFR and to promote safety and quality in all aspects of HFR related activities. The assurance of safe and efficient operation and exploitation of the HFR is condensed together under the concepts of safety and quality of services and is achieved through the safety and quality management.

    The proper use of healthcare informatics technology and multidimensional conceptual clarity are fundamental to create and boost outstanding clinical and telepractice results. Avoiding even terminology ambiguities is mandatory for high quality of care service. For instance, well-being or wellbeing is a different way to write the same concept only, or there is a good deal of ambiguity around the meanings of these terms the way they are written. In personal health, healthcare and healthcare informatics, this kind of ambiguity and lack of conceptual clarity has been called out repeatedly over the past 50 years. It is time to get the right, terse scenario. We present a brief review to develop and achieve ultimate wellbeing understanding for practical high quality healthcare informatics and telepractice application. This article presents an innovative point of view on deeper wellbeing understanding towards its increased clinical effective application.

    In this paper we demonstrate high-quality, uniform dry transfer of graphene grown by chemical vapor deposition on copper foil to polystyrene. The dry transfer exploits an azide linker molecule to establish a covalent bond to graphene and to generate greater graphene-polymer adhesion compared to that of the graphene-metal foil. Thus, this transfer approach provides a novel alternative route for graphene transfer, which allows for the metal foils to be reused. © 2011 American Chemical Society

    Full Text Available Abstract Background Preparation of large quantity and high quality genomic DNA from a large number of plant samples is a major bottleneck for most genetic and genomic analyses, such as, genetic mapping, TILLING (Targeting Induced Local Lesion IN Genome, and next-generation sequencing directly from sheared genomic DNA. A variety of DNA preparation methods and commercial kits are available. However, they are either low throughput, low yield, or costly. Here, we describe a method for high throughput genomic DNA isolation from sorghum [Sorghum bicolor (L. Moench] leaves and dry seeds with high yield, high quality, and affordable cost. Results We developed a high throughput DNA isolation method by combining a high yield CTAB extraction method with an improved cleanup procedure based on MagAttract kit. The method yielded large quantity and high quality DNA from both lyophilized sorghum leaves and dry seeds. The DNA yield was improved by nearly 30 fold with 4 times less consumption of MagAttract beads. The method can also be used in other plant species, including cotton leaves and pine needles. Conclusion A high throughput system for DNA extraction from sorghum leaves and seeds was developed and validated. The main advantages of the method are low cost, high yield, high quality, and high throughput. One person can process two 96-well plates in a working day at a cost of $0.10 per sample of magnetic beads plus other consumables that other methods will also need.

    Full Text Available Abstract Background Malaria is a major cause of morbidity and mortality worldwide with over one million deaths annually, particularly in children under five years. This study was the first to examine plasma cytokines, chemokines and cellular immune responses in pre-school Nigerian children infected with Plasmodium falciparum from four semi-urban villages near Ile-Ife, Osun State, Nigeria. Methods Blood was obtained from 231 children (aged 39–73 months who were classified according to mean P. falciparum density per μl of blood (uninfected (n = 89, low density (10,000, n = 22. IL-12p70, IL-10, Nitric oxide, IFN-γ, TNF, IL-17, IL-4 and TGF-β, C-C chemokine RANTES, MMP-8 and TIMP-1 were measured in plasma. Peripheral blood mononuclear cells were obtained and examined markers of innate immune cells (CD14, CD36, CD56, CD54, CD11c AND HLA-DR. T-cell sub-populations (CD4, CD3 and γδTCR were intracellularly stained for IL-10, IFN-γ and TNF following polyclonal stimulation or stimulated with malaria parasites. Ascaris lumbricoides was endemic in these villages and all data were analysed taking into account the potential impact of bystander helminth infection. All data were analysed using SPSS 15 for windows and in all tests, p Results The level of P. falciparum parasitaemia was positively associated with plasma IL-10 and negatively associated with IL-12p70. The percentage of monocytes was significantly decreased in malaria-infected individuals while malaria parasitaemia was positively associated with increasing percentages of CD54+, CD11c+ and CD56+ cell populations. No association was observed in cytokine expression in mitogen-activated T-cell populations between groups and no malaria specific immune responses were detected. Although A. lumbricoides is endemic in these villages, an analysis of the data showed no impact of this helminth infection on P. falciparum parasitaemia or on immune responses associated with P. falciparum infection

    Normal weight obesity is defined as having excessive body fat, but normal BMI. Even though previous research revealed that excessive body fat in children inhibited their physical activity and decreased motor performance, there has been only little evidence about motor performance of normal weight obese children. This study aims to establish whether normal weight obese pre-school children aged 3-6 years will have a significantly worse level of fundamental motor skills compared to normal weight non-obese counterparts. The research sample consisted of 152 pre-schoolers selected from a specific district of Prague, the Czech Republic. According to values from four skinfolds: triceps, subscapula, suprailiaca, calf, and BMI three categories of children aged 3-6 years were determined: A) normal weight obese n = 51; B) normal weight non-obese n = 52; C) overweight and obese n = 49. The Movement Assessment Battery for Children (MABC-2) was used for the assessment of fundamental motor skills. Normal weight obese children had significantly higher amount of adipose tissue p < 0.001 than normal weight non-obese children but the same average BMI. Moreover, normal weight obese children did not have significantly less amount of subcutaneous fat on triceps and calf compared to their overweight and obese peers. In majority of MABC-2 tests, normal weight obese pre-schoolers showed the poorest performance. Moreover, normal weight obese children had significantly worse total standard score = 38.82 compared to normal weight non-obese peers = 52.27; p < 0.05. In addition, normal weight obese children had a more than three times higher frequency OR = 3.69 CI95% (1.10; 12.35) of severe motor deficit performance ≤ 5 th centile of the MABC-2 norm. These findings are strongly alarming since indices like BMI are not able to identify normal weight obese individual. We recommend verifying real portion of normal weight obese children as they are probably in higher risk of health and motor

    An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

    High efficient mask logistics as well as safe and high quality mask storage are essential requirements within an advanced lithography area of a modern logic waferfab. Fast operational availability of the required masks at the exposure tool with excellent mask condition requires a safe mask handling, safeguarding of high mask quality over the whole mask usage time without any quality degradation and an intelligent mask logistics. One big challenge is the prevention of haze on high advanced phase shift masks used in a high volume production line for some thousands of 248nm or 193nm exposures. In 2008 Infineon Dresden qualified a customer specific developed semi-bare mask storage system from DMSDynamic Micro Systems in combination with a high advanced mask handling and an interconnected complex logistic system. This high-capacity mask storage system DMS M1900.22 for more than 3000 masks with fully automated mask and box handling as well as full-blown XCDA purge has been developed and adapted to the Infineon Lithotoollandscape using Nikon and SMIF reticle cases. Advanced features for ESD safety and mask security, mask tracking via RFID and interactions with the exposure tools were developed and implemented. The stocker is remote controlled by the iCADA-RSM system, ordering of the requested mask directly from the affected exposure tool allows fast access. This paper discusses the advantages and challenges for this approach as well as the practical experience gained during the implementation of the new system which improves the fab performance with respect to mask quality, security and throughput. Especially the realization of an extremely low and stable humidity level in addition with a well controlled air flow at each mask surface, preventing masks from haze degradation and particle contamination, turns out to be a notable technical achievement. The longterm stability of haze critical masks has been improved significantly. Relevant environmental parameters like

    Single-domain antibodies libraries of heavy-chain only immunoglobulins from camelids or shark are enriched for high-affinity antigen-specific binders by a short in vivo immunization. Thus, potent binders are readily retrieved from relatively small-sized libraries of 10 7 -10 8 individual transformants, mostly after phage display and panning on a purified target. However, the remaining drawback of this strategy arises from the need to generate a dedicated library, for nearly every envisaged target. Therefore, all the procedures that shorten and facilitate the construction of an immune library of best possible quality are definitely a step forward. In this chapter, we provide the protocol to generate a high-quality immune VHH library using the Golden Gate Cloning strategy employing an adapted phage display vector where a lethal ccdB gene has to be substituted by the VHH gene. With this procedure, the construction of the library can be shortened to less than a week starting from bleeding the animal. Our libraries exceed 10 8 individual transformants and close to 100% of the clones harbor a phage display vector having an insert with the length of a VHH gene. These libraries are also more economic to make than previous standard approaches using classical restriction enzymes and ligations. The quality of the Nanobodies that are retrieved from immune libraries obtained by Golden Gate Cloning is identical to those from immune libraries made according to the classical procedure.

    Concurrent with the decision to use bellows stem sealed nuclear valves where feasible in commercial-scale CANDU plants, AECL undertook to develop an indigenous high pressure valve bellows technology. This program included developing the capability to fabricate improved high pressure valve bellows in conjunction with a Canadian manufacturer. This paper describes the evolution of a two-stage bellows fabrication process involving: (1) manufacture of discrete lengths of precision thin wall telescoping tubes - from preparation of strip blanks through edge grinding and edge forming to longitudinal welding; (2) forming of bellows from tube assemblies using a novel combination of mechanical inward forming followed by hydraulic outward forming. Bellows of Inconel 600 and Inconel 625 have been manufactured and evaluated. Test results indicate comparable to improved performance over alternative high quality bellows. (author)

  9. Fat Quality Influences the Obesogenic Effect of High Fat Diets

    Full Text Available High fat and/or carbohydrate intake are associated with an elevated risk for obesity and chronic diseases such as diabetes and cardiovascular diseases. The harmful effects of a high fat diet could be different, depending on dietary fat quality. In fact, high fat diets rich in unsaturated fatty acids are considered less deleterious for human health than those rich in saturated fat. In our previous studies, we have shown that rats fed a high fat diet developed obesity and exhibited a decrease in oxidative capacity and an increase in oxidative stress in liver mitochondria. To investigate whether polyunsaturated fats could attenuate the above deleterious effects of high fat diets, energy balance and body composition were assessed after two weeks in rats fed isocaloric amounts of a high-fat diet (58.2% by energy rich either in lard or safflower/linseed oil. Hepatic functionality, plasma parameters, and oxidative status were also measured. The results show that feeding on safflower/linseed oil diet attenuates the obesogenic effect of high fat diets and ameliorates the blood lipid profile. Conversely, hepatic steatosis and mitochondrial oxidative stress appear to be negatively affected by a diet rich in unsaturated fatty acids.

    High quality electron beams have been produced in a laser-plasma accelerator driven by femtosecond laser pulses with a peak power of 26 TW. Electrons are produced with an energy up to 150 MeV from the 2 mm gas jet accelerator and the measured rms relative energy spread is less than 1%. Shot-to-shot stability in the central energy is 3%. Pepper-pot measurements have shown that the normalized transverse emittance is {approx}1{pi} mm mrad while the beam charge is in the range 2-10 pC. The generation of high quality electron beams is understood from simulations accounting for beam loading of the wakefield accelerating structure. Experiments and self-consistent simulations indicate that the beam peak current is several kiloamperes. Efficient transportation of the beam through an undulator is simulated and progress is being made towards the realization of a compact, high peak brilliance free-electron laser operating in the vacuum ultraviolet and soft x-ray wavelength ranges.

    Full Text Available Introduction: Birth weight is one of the most important indicators of infant's health and could predict their health condition in future. This study was conducted to determine and compare indicators of growth [weight, height, and body mass index (BMI] and behavioral disorders in children with normal, low, and very low birth weight at pre-school age. Materials and Methods: In this descriptive analytical study, 236 children (126 with normal weight, 100 with low birth weight, and 10 with very low birth weight at pre-school age were investigated in three groups. Data collection tools were a two-part questionnaire including the Rutter Children Behavior Questionnaire for parents, and parents' and children's demographic characteristics questionnaire, scale, and stadiometer. Data were analyzed using descriptive statistics, variance analysis, Chi square, and Kruskal–Wallis tests. Results: The mean of weight, height, and BMI at pre-school age in three groups had a significant difference (P = 0.009 and it was lower in the group with very low birth weight than the other two groups; however, the difference between the group with normal birth weight and the group with low birth weight was not significant (P = 0.10. The mean score of behavioral disorder had no significant difference between groups (P = 0.49. Conclusions: Results showed that children with very low birth weight grew less than the other two groups. Therefore, this group needs special attention and long-term follow-up for taking care of them to ensure better growth. It is recommended to conduct more extended studies to evaluate behavioral disorders in these children.

    Sleep is one of the most basic human requirements. This research aims at determining the status of sleep quality and its relationship with quality of life among high-risk pregnant women in Tabriz, Iran, in 2015. This research was a sectional study done on 364 qualified women in 28-36 weeks of pregnancy suffering from mild preeclampsia and gestational diabetes. The sampling was done as convenience. Personal-social-midwifery questionnaire, Pittsburg sleep quality, and quality of life in pregnancy (QOL-ORAV) were used for gathering data. Multivariate linear regression model was used for determining the relationship between sleep quality and its subsets with quality of life and controlling confounders. In the current study, the prevalence of sleep disturbance was 96.4%. Mean (SD) of the total score of sleep quality was 10.1 (4.1) and the total score of quality of life was 61.7 (17.3). According to Pearson's correlation test, there was statistically significant relationship between quality of life and sleep quality and all its subsets except sleep duration and use of sleep medication (p quality of life. The findings of current research show that sleep quality is low among high-risk pregnant women and quality of life is medium. So, it is necessary that required training is given by health cares for improving sleep quality and quality of life to mothers.

    We present a detailed investigation of the anti-Stokes (AS) luminescence which originates from exciton recombination when below gap excitation is used, in a set of high quality quantum well structures. We observe strong excitonic resonances in the AS signal as measured from photoluminescence and photoluminescence excitation spectra. We demonstrate that neither the electromagnetic coupling between the wells nor the morphological disorder can explain this up-conversion effect. Time-resolved luminescence data after ps excitation and fs correlation spectroscopy results provide clear evidence of the occurrence of a two-step absorption which is assisted by the exciton population resonantly excited by the first photon.

    Supplement 17 of the British Journal of Radiology is a survey of central-axis depth doses for radiotherapy machines, patterned largely on BJR Supplement 11 (1972). Inspection of high-energy X-ray depth doses for a 10 x 10 cm field at an SSD of 100 cm disclosed large differences between the two sets of data, especially for qualities above 8 MV, e.g. a depth dose of 80% at 10 cm is rated at about 19 MV according to BJR Supplement 11, and 23 MV according to BJR Supplement 17. It was found that Supplement 17 depth-dose data above 8 MV were erratic, but Supplement 11 data could be represented by an analytical expression, providing a unique means of assigning MV quality. It was also found that dose-weighted average energy of the filtered beam plotted smoothly against depth dose. For dosimetric purposes, it is suggested that this parameter be used as a true measure of beam quality, removing discrepancies introduced by the use of nominal MV for this purpose. (author)

    This is a reference book for amateur astronomers who have become interested in CCD imaging. Those glorious astronomical images found in astronomy magazines might seem out of reach to newcomers to CCD imaging, but this is not the case. Great pictures are attainable with modest equipment. Adam Stuart’s many beautiful images, reproduced in this book, attest to the quality of – initially – a beginner’s efforts. Chilled-chip astronomical CCD-cameras and software are also wonderful tools for cutting through seemingly impenetrable light-pollution. CCD Astrophotography from the Suburbs describes one man’s successful approach to the problem of getting high-quality astronomical images under some of the most light-polluted conditions. Here is a complete and thoroughly tested program that will help every CCD-beginner to work towards digital imaging of the highest quality. It is equally useful to astronomers who have perfect observing conditions, as to those who have to observe from light-polluted city skies.

    Full Text Available A presente pesquisa com crianças pré-escolares enfoca as relações afetivas como elementos indispensáveis à compreensão do crescimento da criança e os papéis da família e da escola nesse empreendimento. Assim, seu objetivo central consistiu na análise das interações afetivas de crianças na família e na pré-escola. Participaram 40 crianças de 4 a 6 anos, matriculadas em uma instituição pré-escolar municipal, localizada no interior do Estado de São Paulo, suas mães e dez professoras. Foram utilizados como instrumentos a observação, o questionário e a entrevista. O primeiro dirigiu-se ao comportamento das crianças no contexto pré-escolar, o segundo ao comportamento das professoras com as crianças e o terceiro destinou-se às mães, cujas verbalizações permitiram constatar as relações interpessoais no ambiente familiar. Os resultados revelaram que as crianças com dificuldades nas relações interpessoais na escola também as apresentavam no ambiente familiar.This research with pre-school children focused affective relations as indispensable elements to understand the growing of a child, and the role of the family and the school in such achievement. Its main goal consisted in the analysis of the affective interactions of children in the family and in pre-school. 40 children (4-6 years old from a municipal pre-school institution (in the State of São Paulo took part in the study, as well as their mothers and 10 teachers. Three instruments have been utilized: observation, questionnaire and interview. The first was used to investigate children's behavior in the pre-school context; the second one referred to the teachers' attitude toward the children, and the third one was dedicated to the mothers, whose verbalizations unveiled the personal relationships in the familiar environment. The results revealed that children with personal relationship problems at school, also presented the same problem at home.

    We evaluated the reliability of a rotational angiographic unit (RA) with flat-panel detector as a single technique to guide percutaneous vertebroplasty (PVP) and for post-procedure assessment by 2D and 3D reformatted images. Fifty-five consecutive patients (104 vertebral bodies) were treated under RA fluoroscopy. Rotational acquisitions with 2D and 3D reconstruction were obtained in all patients for immediate post-procedure assessment. In complex cases, this technique was also used to evaluate the needle position during the procedure. All patients underwent CT scan after the procedure. RA and CT findings were compared. In all cases, a safe trans-pedicular access and an accurate control of the bone-cement injection were successfully performed with high-quality fluoroscopy, even at the thoracic levels and in case of vertebra plana. 2D and 3D rotational reconstructions permitted CT-like images that clearly showed needle position and were similar to CT findings in depicting intrasomatic implant-distribution. RA detected 40 cement leakages compared to 42 demonstrated by CT and showed overall 95% sensitivity and 100% specificity compared to CT for final post-procedure assessment. Our preliminary results suggest that high-quality RA is reliable and safe as a single technique for PVP guidance, control and post-procedure assessment. It permits fast and cost-effective procedures avoiding multi-modality imaging.

    Full Text Available The study discusses the possibility of control of the high-quality grey cast iron and ductile iron using the author’s genuine computer programs. The programs have been developed with the help of algorithms based on statistical relationships that are said to exist between the characteristic parameters of DTA curves and properties, like Rp0,2, Rm, A5 and HB. It has been proved that the spheroidisation and inoculation treatment of cast iron changes in an important way the characteristic parameters of DTA curves, thus enabling a control of these operations as regards their correctness and effectiveness, along with the related changes in microstructure and mechanical properties of cast iron. Moreover, some examples of statistical relationships existing between the typical properties of ductile iron and its control process were given for cases of the melts consistent and inconsistent with the adopted technology.A test stand for control of the high-quality cast iron and respective melts has been schematically depicted.

  20. Automated high speed volume computed tomography for inline quality control

    Hanke, R.; Kugel, A.; Troup, P.

    2004-01-01

    Increasing complexity of innovative products as well as growing requirements on quality and reliability call for more detailed knowledge about internal structures of manufactured components rather by 100 % inspection than just by sampling test. A first-step solution, like radioscopic inline inspection machines, equipped with automated data evaluation software, have become state of the art in the production floor during the last years. However, these machines provide just ordinary two-dimensional information and deliver no volume data e.g. to evaluate exact position or shape of detected defects. One way to solve this problem is the application of X-ray computed tomography (CT). Compared to the performance of the first generation medical scanners (scanning times of many hours), today, modern Volume CT machines for industrial applications need about 5 minutes for a full object scan depending on the object size. Of course, this is still too long to introduce this powerful method into the inline production quality control. In order to gain acceptance, the scanning time including subsequent data evaluation must be decreased significantly and adapted to the manufacturing cycle times. This presentation demonstrates the new technical set up, reconstruction results and the methods for high-speed volume data evaluation of a new fully automated high-speed CT scanner with cycle times below one minute for an object size of less than 15 cm. This will directly create new opportunities in design and construction of more complex objects. (author)

    This paper described a pressurized microfiltration membrane system installed at an oil sands extraction site in Alberta. The system was designed to complement a reverse osmosis (RO) system installed at the site to produce the high quality feed water required by the system's boilers. Groundwater in the region exhibited moderate total suspended solids and high alkalinity and hardness levels, and the RO system required feed water with a silt density index of 3 or less. The conventional pretreatment system used at the site was slowing down production due to the severe fouling of the RO membranes. The new microfiltration system contained an automated PVDF hollow fiber microfiltration membrane system contained in a trailer. Suspended particles and bacteria were captured within the filter, and permeate was sent to the RO unit. Within 6 hours of being installed, the unit was producing water with SDI values in the range of 1.0 to 2.5. It was concluded that the microfiltration system performed reliably regardless of wide variations in feed water quality and flow rates. 3 refs., 1 tab., 8 figs.

    Full Text Available Cardiovascular disease (CVD risk factors, such as diabetes, hypertension, hypercholesterolemia, smoking, and obesity tend to occur together in the general population. Increasing prevalence of multiple CVD risk factors has been related to increased risk of death from coronary heart disease and stroke. Studies have suggested that people with several risk factors of CVD may have impaired health-related quality of life. The objective of this study was to assess the association of CVD risk factors with quality of life (QOL among adults aged 40 to 65 years. A cross-sectional study was conducted involving 220 subjects 40 - 65 years of age at a health center. The CVD risk factors were assessed using the Framingham risk score that is the standard instrument for assessment of the risk of a first cardiac event. The risk factors assessed were age, smoking, blood pressure, total cholesterol and high density lipoprotein cholesterol concentrations. QOL was assessed by means of the WHOQOL-BREF instrument that had been prevalidated. The results of the study showed that 28.2% of subjects were smokers, 56.4% had stage 1 hypertension, 42.8% high total cholesterol and 13.6% low HDL cholesterol. The high risk group amounted to 45.5% and 42.3% constitued an intermediate risk group. High CVD risk scores were significantly associated with a low QOL for all domains (physical, psychological, social and environment (p=0.000. Preventing or reducing the multiple CVD risk factors to improve QOL is necessary among adults.

  3. Automated Theorem Proving in High-Quality Software Design

    The amount and complexity of software developed during the last few years has increased tremendously. In particular, programs are being used more and more in embedded systems (from car-brakes to plant-control). Many of these applications are safety-relevant, i.e. a malfunction of hardware or software can cause severe damage or loss. Tremendous risks are typically present in the area of aviation, (nuclear) power plants or (chemical) plant control. Here, even small problems can lead to thousands of casualties and huge financial losses. Large financial risks also exist when computer systems are used in the area of telecommunication (telephone, electronic commerce) or space exploration. Computer applications in this area are not only subject to safety considerations, but also security issues are important. All these systems must be designed and developed to guarantee high quality with respect to safety and security. Even in an industrial setting which is (or at least should be) aware of the high requirements in Software Engineering, many incidents occur. For example, the Warshaw Airbus crash, was caused by an incomplete requirements specification. Uncontrolled reuse of an Ariane 4 software module was the reason for the Ariane 5 disaster. Some recent incidents in the telecommunication area, like illegal "cloning" of smart-cards of D2GSM handies, or the extraction of (secret) passwords from German T-online users show that also in this area serious flaws can happen. Due to the inherent complexity of computer systems, most authors claim that only a rigorous application of formal methods in all stages of the software life cycle can ensure high quality of the software and lead to real safe and secure systems. In this paper, we will have a look, in how far automated theorem proving can contribute to a more widespread application of formal methods and their tools, and what automated theorem provers (ATPs) must provide in order to be useful.

  4. SOME ASPECTS OF TEACHING MEDIA LITERACY TO PRE-SCHOOL CHILDREN IN SLOVENIA FROM A PERCEPTION STANDPOINT OF TEACHERS AND PARENTS

    Jurka Lepičnik Vodopivec

    2011-11-01

    Full Text Available This paper deals with media literacy as a multidimensional skill that parents and teachers possess. In this context we warn of the media-technical aspect of this skill and, within this aspect, of parents’ and teachers’ opinion on the presence of media in children’s lives. Following that, the paper explores teachers’ media-didactic competence as a component of educators’ media literacy. In the empiric part we used two aspects of fostering media literacy. One is the media-technical competence of parents and educators, while the other is the media-didactic competence of educators. We found that both parents and teachers believe that media have a strong presence in everyday lives of pre-school children and that they play an important role in teaching pre-school children. Teachers are aware of the importance of early teaching with media, for media and about media with the purpose of developing children’s media literacy, so they will not be afraid of media when they grow up.

    Full Text Available English language teaching has newly been introduced to pre-school curriculum in Turkey. The purpose of this study was to investigate the effectiveness of teaching EFL vocabulary to pre-school children through Project Based Learning (PBL. For this purpose, an experimental design, consisted of observation checklists, exam scores and a short survey, was adopted. Firstly, through a short online survey, 150 kindergarten teachers were asked to specify which techniques they commonly used in their English classes. The primary aim here was to define traditional techniques and the rate of PBL use in Turkey. After defining common techniques, 28 children were randomly assigned to experimental (PBL instruction and control groups (traditional instruction equally and the data was collected in real time classroom setting for 8 weeks. The results showed that (1 PBL was rarely adopted in EFL classes in Turkey, (2 PBL instruction could increase EFL vocabulary learning gains when compared to common methods and (3 young learners were observed to have been more active in PBL classes. The effect of PBL instruction was discussed in local, cognitive and motivational perspectives in the light of previous related research. The potential benefits of further PBL use for young EFL learners and implications were also discussed.

    To assess the dependence on fish consumption of families and its impact on nutritional status and neurodevelopment of pre-school children. Cross-sectional study that measured children's hair mercury (HHg) as an indicator of family fish consumption, growth (anthropometric Z-scores, WHO standards) and neurological (Gesell developmental scores (GDS)) development. Traditional living conditions among families residing in the area adjacent to the Samuel Dam (Western Amazon) hydroelectric reservoir. Two hundred and forty-nine pre-school children (1-59 months of age) from families transitioning from the traditional Amazonian lifestyle. Family fish consumption was significantly correlated with children's HHg concentration (Spearman's r=0.246, P85), multiple regression analysis showed that fish consumption (as HHg) had no impact on GDS, but that some variables did interact significantly with specific domains (motor and language development). The study showed that the families' shift in fish consumption had no negative impact on the growth of young children and that ensuing methylmercury exposure has not been a noticeable neurodevelopmental hindrance.

    The purpose of this study was to determine the number of hours and days of accelerometry data necessary to provide a reliable estimate of habitual physical activity in pre-school children. The impact of a weekend day on reliability estimates was also determined and standard measurement days were defined for weekend and weekdays.Accelerometry data were collected from 112 children (60 males, 52 females, mean (SD) 3.7 (0.7)yr) over 7 d. The Spearman-Brown Prophecy formula (S-B prophecy formula) was used to predict the number of days and hours of data required to achieve an intraclass correlation coefficient (ICC) of 0.7. The impact of including a weekend day was evaluated by comparing the reliability coefficient (r) for any 4 d of data with data for 4 d including one weekend day.Our observations indicate that 3 d of accelerometry monitoring, regardless of whether it includes a weekend day, for at least 7 h  d(-1) offers sufficient reliability to characterise total physical activity and sedentary behaviour of pre-school children. These findings offer an approach that addresses the underlying tension in epidemiologic surveillance studies between the need to maintain acceptable measurement rigour and retention of a representatively meaningful sample size.

    Full Text Available The development of easy-to-use and accurate methods to assess the intake of energy, foods and nutrients in pre-school children is needed. KidMeal-Q is an online food frequency questionnaire developed for the LifeGene prospective cohort study in Sweden. The aims of this study were to compare: (i energy intake (EI obtained using KidMeal-Q to total energy expenditure (TEE measured via doubly labelled water and (ii the intake of certain foods measured using KidMeal-Q to intakes acquired by means of 24 h dietary recalls in 38 children aged 5.5 years. The mean EI calculated using KidMeal-Q was statistically different (p < 0.001 from TEE (4670 ± 1430 kJ/24 h and 6070 ± 690 kJ/24 h, respectively. Significant correlations were observed for vegetables, fruit juice and candy between KidMeal-Q and 24 h dietary recalls. Only sweetened beverage consumption was significantly different in mean intake (p < 0.001, as measured by KidMeal-Q and 24 h dietary recalls. In conclusion, KidMeal-Q had a relatively short answering time and comparative validity to other food frequency questionnaires. However, its accuracy needs to be improved before it can be used in studies in pre-school children.

  9. Recruiting and retaining high-quality teachers in rural areas.

    Monk, David H

    2007-01-01

    In examining recruitment and retention of teachers in rural areas, David Monk begins by noting the numerous possible characteristics of rural communities--small size, sparse settlement, distance from population concentrations, and an economic reliance on agricultural industries that are increasingly using seasonal and immigrant workers to minimize labor costs. Many, though not all, rural areas, he says, are seriously impoverished. Classes in rural schools are relatively small, and teachers tend to report satisfaction with their work environments and relatively few problems with discipline. But teacher turnover is often high, and hiring can be difficult. Monk observes that rural schools have a below-average share of highly trained teachers. Compensation in rural schools tends to be low, perhaps because of a lower fiscal capacity in rural areas, thus complicating efforts to attract and retain teachers. Several student characteristics, including relatively large shares of students with special needs and with limited English skills and lower shares of students attending college, can also make it difficult to recruit and retain high-quality teachers. Other challenges include meeting the needs of highly mobile children of low-income migrant farm workers. With respect to public policy, Monk asserts a need to focus on a subcategory of what might be called hard-to-staff rural schools rather than to develop a blanket set of policies for all rural schools. In particular, he recommends a focus on such indicators as low teacher qualifications, teaching in fields far removed from the area of training, difficulty in hiring, high turnover, a lack of diversity among teachers in the school, and the presence of migrant farm workers' children. Successful efforts to stimulate economic growth in these areas would be highly beneficial. He also calls attention to the potential for modern telecommunication and computing technologies to offset some of the drawbacks associated with teaching

    A Quality Assurance program should be installed also for High Dose Rate brachytherapy, in the order to achieve a correct dose administration to the patient and for the safety to those involved directly with the treatment. The work presented here has the following purposes: Analyze the types of equipment tests presented by the official protocols (TG40, TG56 e ARCAL XXX), evaluate the brachytherapy routine tests of protocols from various national and international radiotherapy services and compare the latter with those presented in the official protocols. As a result, we conclude the following: TG56 presents a higher number of tests when compared to the other official protocols and most of the tests presented by the analyzed services are present in TG56. A suggestion for a basic protocol is presented, emphasizing the periodicity and tolerance level of each of the tests. (author)

    2013-06-01

    The aim of the paper is to obtain a high quality Diesel fuel by hydro-deoxigenation of vegetable oils (VO) mixed with a low sulfur gasoil (LSGO). The process is possible by using a bi-functional catalyst Ni-Mo supported by an activated Al{sub 2}O{sub 3} containing 2% Ultrastable Y-zeolite. The experimental conditions were: T =340 - 380 C, Pressure = 50 bar, LHSV = 1,5 h{sup -1}, H{sub 2}/Feed ratio = 15 mole H{sub 2} /mole liquid feed. The liquid product was separated in two fractions: a light distillate (similar to gasoline) and a heavy distillate (boiling point > 200 C) with very good characteristics for Diesel engines. The reaction chemistry is very complex, but the de-oxygenation process is decisive for the chemical structure of hydrocarbons from final product. Finally, a schema for the reaction mechanism is proposed. (orig.)

    High-quality graphene scrolls (GSS) with a unique scrolled topography are designed using a microexplosion method. Their capacitance properties are investigated by cyclic voltammetry, galvanostatic charge-discharge and electrical impedance spectroscopy. Compared with the specific capacity of 110 F g-1 for graphene sheets, a remarkable capacity of 162.2 F g-1 is obtained at the current density of 1.0 A g-1 in 6 M KOH aqueous solution owing to the unique scrolled structure of GSS. The capacity value is increased by about 50% only because of the topological change of graphene sheets. Meanwhile, GSS exhibit excellent long-term cycling stability along with 96.8% retained after 1000 cycles at 1.0 A g-1. These encouraging results indicate that GSS based on the topological structure of graphene sheets are a kind of promising material for supercapacitors.

    We have extended the off-axis biepitaxial technique to produce YBCO grain boundary junctions on low loss substrates. Excellent transport properties have been reproducibly found, with remarkable values of the quality factor I{sub c}R{sub n} (with I{sub c} the critical current and R{sub n} the normal state resistance) above 10 mV, far higher than the values commonly reported in the literature for high temperature superconductor (HTS) based Josephson junctions. The outcomes are consistent with a picture of a more uniform grain boundary region along the current path. This work supports a possible implementation of grain boundary junctions for various applications including terahertz sensors and HTS quantum circuits in the presence of microwaves.

    Full Text Available We undertook a detailed ethnographic study of the dance creation process of a noted choreographer and his distinguished troupe. All choreographer dancer interactions were videoed, the choreographer and dancers were interviewed extensively each day, as well as other observations and tests performed. The choreographer used three main methods to produce high quality and novel content: showing, making-on, and tasking. We present, analyze and evaluate these methods, and show how these approaches allow the choreographer to increase the creative output of the dancers and him. His methods, although designed for dance, apply more generally to other creative endeavors, especially where brainstorming is involved, and where the creative process is distributed over many individuals. His approach is also a case study in multi-modal direction, owing to the range of mechanisms he uses to communicate and direct.

    Full Text Available Abstract Background In the postgenomic era, high throughput protein expression and protein microarray technologies have progressed markedly permitting screening of therapeutic reagents and discovery of novel protein functions. Hexa-histidine is one of the most commonly used fusion tags for protein expression due to its small size and convenient purification via immobilized metal ion affinity chromatography (IMAC. This purification process has been adapted to the protein microarray format, but the quality of in situ His-tagged protein purification on slides has not been systematically evaluated. We established methods to determine the level of purification of such proteins on metal chelate-modified slide surfaces. Optimized in situ purification of His-tagged recombinant proteins has the potential to become the new gold standard for cost-effective generation of high-quality and high-density protein microarrays. Results Two slide surfaces were examined, chelated Cu2+ slides suspended on a polyethylene glycol (PEG coating and chelated Ni2+ slides immobilized on a support without PEG coating. Using PEG-coated chelated Cu2+ slides, consistently higher purities of recombinant proteins were measured. An optimized wash buffer (PBST composed of 10 mM phosphate buffer, 2.7 mM KCl, 140 mM NaCl and 0.05% Tween 20, pH 7.4, further improved protein purity levels. Using Escherichia coli cell lysates expressing 90 recombinant Streptococcus pneumoniae proteins, 73 proteins were successfully immobilized, and 66 proteins were in situ purified with greater than 90% purity. We identified several antigens among the in situ-purified proteins via assays with anti-S. pneumoniae rabbit antibodies and a human patient antiserum, as a demonstration project of large scale microarray-based immunoproteomics profiling. The methodology is compatible with higher throughput formats of in vivo protein expression, eliminates the need for resin-based purification and circumvents

The addition to Fe-C-Al alloy V, Ti, Cr leads to the improvement of functional and mechanical cast qualities. In this study, a method was investigated to eliminate the presence of undesirable Al4C3 phases in a aluminium cast iron structure and thus improve the production process. V and Ti additions in aluminium cast iron allows to development of FeAl - VC or TiC alloys. In particular, V or Ti contents above 5 wt.% were found to totally eliminate the presence of Al4C3. In addition, preliminary work indicates that the alloy with the FeAl - VC or TiC structure reveals high oxidation resistance. The introduction of 5 wt.% chromium to aluminium cast iron strengthened Al4C3 precipitate. Thus, the resultant alloy can be considered an intermetallic FeAl matrix strengthened by VC and TiC or modified Al4C3 reinforcements.

    The SonicBREWS project (Sonic Boom Resistant Earthquake Warning Systems) is a collaborative effort between Seismic Warning Systems, Inc. and NASA Dryden Flight Research Center. This project aims to evaluate the effects of sonic booms on Earthquake Warning Systems in order to prevent such systems from experiencing false alarms due to sonic booms. The airspace above the Antelope Valley, California includes the High Altitude Supersonic Corridor and the Black Mountain Supersonic Corridor. These corridors are among the few places in the US where supersonic flight is permitted, and sonic booms are commonplace in the Antelope Valley. One result of this project is a rich dataset of high-quality accelerometer records of sonic booms which can shed light on the interaction between these atmospheric phenomena and the solid earth. Nearly 100 sonic booms were recorded with low-noise triaxial MEMS accelerometers recording 1000 samples per second. The sonic booms had peak overpressures ranging up to approximately 10 psf and were recorded in three flight series in 2010 and 2011. Each boom was recorded with up to four accelerometers in various array configurations up to 100 meter baseline lengths, both in the built environment and the free field. All sonic booms were also recorded by nearby microphones. We present the results of the project in terms of the potential for sonic-boom-induced false alarms in Earthquake Warning Systems, and highlight some of the interesting features of the dataset.

    We present a high-quality display system that enables the remote access within an operating theatre of high-end medical imaging and surgical planning software. Currently, surgeons often use printouts from such software for reference during surgery; our system enables surgeons to access and review patient data in a sterile environment, viewing real-time renderings of MRI & CT data as required. Once calibrated, our system displays shades of grey in Operating Room lighting conditions (removing any gamma correction artefacts). Our system does not require any expensive display hardware, is unobtrusive to the remote workstation and works with any application without requiring additional software licenses. To extend the native 256 levels of grey supported by a standard LCD monitor, we have used the concept of "PseudoGrey" where slightly off-white shades of grey are used to extend the intensity range from 256 to 1,785 shades of grey. Remote access is facilitated by a customized version of UltraVNC, which corrects remote shades of grey for display in the Operating Room. The system is successfully deployed at Morriston Hospital, Swansea, UK, and is in daily use during Maxillofacial surgery. More formal user trials and quantitative assessments are being planned for the future.

    Childbirth Connection hosted a 90th Anniversary national policy symposium, Transforming Maternity Care: A High Value Proposition, on April 3, 2009, in Washington, DC. Over 100 leaders from across the range of stakeholder perspectives were actively engaged in the symposium work to improve the quality and value of U.S. maternity care through broad system improvement. A multi-disciplinary symposium steering committee guided the strategy from its inception and contributed to every phase of the project. The "Blueprint for Action: Steps Toward a High Quality, High Value Maternity Care System", issued by the Transforming Maternity Care Symposium Steering Committee, answers the fundamental question, "Who needs to do what, to, for, and with whom to improve the quality of maternity care over the next five years?" Five stakeholder workgroups collaborated to propose actionable strategies in 11 critical focus areas for moving expeditiously toward the realization of the long term "2020 Vision for a High Quality, High Value Maternity Care System", also published in this issue. Following the symposium these workgroup reports and recommendations were synthesized into the current blueprint. For each critical focus area, the "Blueprint for Action" presents a brief problem statement, a set of system goals for improvement in that area, and major recommendations with proposed action steps to achieve them. This process created a clear sightline to action that if enacted could improve the structure, process, experiences of care, and outcomes of the maternity care system in ways that when anchored in the culture can indeed transform maternity care.

    Several outbreaks of severe infections due to contamination of gastrointestinal (GI) endoscopes, mainly duodenoscopes, have been described. The rate of microbial endoscope contamination varies dramatically in literature. The aim of this multicentre prospective study was to evaluate the hygiene quality of endoscopes and automated endoscope reprocessors (AERs) in Tyrol/Austria. In 2015 and 2016, a total of 463 GI endoscopes and 105 AERs from 29 endoscopy centres were analysed by a routine (R) and a combined routine and advanced (CRA) sampling procedure and investigated for microbial contamination by culture-based and molecular-based analyses. The contamination rate of GI endoscopes was 1.3%-4.6% according to the national guideline, suggesting that 1.3-4.6 patients out of 100 could have had contacts with hygiene-relevant microorganisms through an endoscopic intervention. Comparison of R and CRA sampling showed 1.8% of R versus 4.6% of CRA failing the acceptance criteria in phase I and 1.3% of R versus 3.0% of CRA samples failing in phase II. The most commonly identified indicator organism was Pseudomonas spp., mainly Pseudomonas oleovorans. None of the tested viruses were detected in 40 samples. While AERs in phase I failed (n = 9, 17.6%) mainly due to technical faults, phase II revealed lapses (n = 6, 11.5%) only on account of microbial contamination of the last rinsing water, mainly with Pseudomonas spp. In the present study the contamination rate of endoscopes was low compared with results from other European countries, possibly due to the high quality of endoscope reprocessing, drying and storage.

    Parental health literacy plays an important role in children’s health, Experiences from pharmacy practice show that is necessary to check if parents understand instructions about use of medicines for children. This study aimed to assess pharmacotherapy literacy of parents of pre-school children and to examine association of parental pharmacotherapy literacy level with parent’s socio-demographic characteristics. The study was cross-sectional, conducted among parents of pre-school children (1⁻7 years of age), in kindergartens in several municipalities of Belgrade, Serbia, during regular parents meetings, from May to October 2016. Functional health literacy was measured by the Serbian version of the Short Test of Functional Health Literacy in Adults (S-TOFHLA). Parental pharmacotherapy literacy was assessed with newly constructed PTHL-SR questionnaire with good psychometric characteristics (Parental pharmacotherapy literacy questionnaire—Serbian). Overall, 813 parents participated in the study, mostly females (81.30%), between 30 to 40 years of age (70.85%) with two children (56.70%). Almost all of our study participants (99%) had adequate health literacy as assessed by S-TOFHLA. Mean score on PTHL-SR was 72.83% (standard deviation was 13.37), with better results among females than males (72% of women were in the group of highest PTHL-SR results). Our study showed that many parents (76.5%) knew the appropriate usage of non-prescription medicine for children, 57.2% parents were able to correctly calculate the dose of oral syrup for a child, and only 43.3% were able to interpret non-prescription dosage information written on the package. The majority of parents (61.3%) would make a dosage to child based on age and not on their weight. Every fifth parent with adequate functional health literacy measured by S-TOFHLA test, achieved the lowest results measured by PTHL-SR. Higher performance of the PTHL-SR was significantly correlated with education ( p information

    The mechanisms that make that the costs of producing high-quality signals are unaffordable to low-quality signalers are a current issue in animal communication. The size of the melanin-based bib of male house sparrows Passer domesticus honestly signals quality. We induced the development of new bibs while treating males with buthionine-sulfoximine (BSO), a substance that depletes the levels of the antioxidant glutathione (GSH) and the amino acid cysteine, two elements that switch melanogenesis from eumelanin to pheomelanin. Final bib size is negatively related to pheomelanin levels in the bib feathers. BSO reduced cysteine and GSH levels in all birds, but improved phenotypes (bibs larger than controls) were only expressed by high-quality birds (BSO birds with largest bibs initially). Negative associations between final bib size and cysteine levels in erythrocytes, and between pheomelanin and cysteine levels, were observed in high-quality birds only. These findings suggest that a mechanism uncoupling pheomelanin and cysteine levels may have evolved in low-quality birds to avoid producing bibs of size not corresponding to their quality and greater relative costs. Indeed, greater oxidative stress in cells was not observed in low-quality birds. This may represent the first mechanism maintaining signal honesty without producing greater relative costs on low-quality signalers. PMID:25330349

    This is the second in a series of articles examining the components of good corporate governance. It considers how the structures and processes for quality governance can affect an organisation's ability to be assured about the quality of care. Complex information systems and procedures can lead to poor quality care, but sound structures and processes alone are insufficient to ensure good governance, and behavioural factors play a significant part in making sure that staff are enabled to provide good quality care. The next article in this series looks at how the information reporting of an organisation can affect its governance.

    The appropriate design of various pieces of safety equipment such as relief systems, relies on the accurate description of critical flow phenomena. Most of the systems of industrial interest are willing to be described by one-dimensional area-averaged models and a large fraction of them involves multi-component high gas quality flows. Within these circumstances, the flow is very likely to be of an annular dispersed nature and its description by two-fluid models requires various closure relations. Among the most sensitive closures, there is the interfacial area and the liquid entrained fraction. The critical flowrate depends tremendously on the accurate description of the non equilibrium which results from the correctness of the closure equations. In this study, two-component flows are emphasized and non equilibrium results mainly form the differences in the phase velocities. It is therefore of the utmost importance to have reliable data to characterize non equilibrium phenomena and to assess the validity of the closure models. A comprehensive description of air-water nozzle flows, with emphasis on the effect of the nozzle geometry, has been undertaken and some of the results are presented here which helps understanding the overall flow dynamics. Besides the critical flowrate, the presented material includes pressure profiles, droplet size and velocity, liquid film flowrate and liquid film thickness

    The purpose of this study was to demonstrate the use of an outcome-driven model of decision-making in the implementation of computer access technology (CAT) for a pre-school child with athetoid cerebral palsy. The child did not have the fine motor skills required to hold a pencil but had the cognitive abilities to learn to write; therefore, we explored the use of a CAT device to enable written communication. Case study methodology was used to describe the selection process, child-level outcomes, and clinical challenges faced by the therapist in the use of a consortium model that was designed for an outcome-driven model of decision-making. The critical role of an occupational therapist in this process using a family-centered approach is discussed.

    Full Text Available We investigated the interaction between social learning factors measured by questionnaires and aggressive and playful behaviors of pre-school children, through direct observation during their playful break time. The subjects were 15 boys between four and six years old who were enrolled in a non-profit child care center in Goiânia-GO, Brazil. A multivariate analysis of variance indicated significant effects of aggressive models at home on aggression levels during playful behavior. Children exposed to abusive physical punishment, adult fighting and violent TV programs engaged in more episodes of aggression during playful breaks. Boys who reported to play with toy guns at home did not engage in aggressive behavior more often than those who did not, but they displayed a higher proportion of pretended aggression. Results also indicated that aggressive behavior becomes more frequent as the number of aggressive models at home increases.

    Summary Background In north India many pre-school children are underweight, many have intestinal worms, and 2–3% die at ages 1·0–6·0 years. We used the state-wide Integrated Child Development Service (ICDS) infrastructure to help to assess any effects of regular deworming on mortality. Methods Participants in this cluster-randomised study were children in catchment areas of 8338 ICDS-staffed village child-care centres (under-5 population 1 million) in 72 administrative blocks. Groups of four neighbouring blocks were cluster-randomly allocated in Oxford between 6-monthly vitamin A (retinol capsule of 200 000 IU retinyl acetate in oil, to be cut and dripped into the child's mouth every 6 months), albendazole (400 mg tablet every 6 months), both, or neither (open control). Analyses of albendazole effects are by block (36 vs 36 clusters). The study spanned 5 calendar years, with 11 6-monthly mass-treatment days for all children then aged 6–72 months. Annually, one centre per block was randomly selected and visited by a study team 1–5 months after any trial deworming to sample faeces (for presence of worm eggs, reliably assessed only after mid-study), weigh children, and interview caregivers. Separately, all 8338 centres were visited every 6 months to monitor pre-school deaths (100 000 visits, 25 000 deaths at age 1·0–6·0 years [the primary outcome]). This trial is registered at ClinicalTrials.gov, NCT00222547. Findings Estimated compliance with 6-monthly albendazole was 86%. Among 2589 versus 2576 children surveyed during the second half of the study, nematode egg prevalence was 16% versus 36%, and most infection was light. After at least 2 years of treatment, weight at ages 3·0–6·0 years (standardised to age 4·0 years, 50% male) was 12·72 kg albendazole versus 12·68 kg control (difference 0·04 kg, 95% CI −0·14 to 0·21, p=0·66). Comparing the 36 albendazole-allocated versus 36 control blocks in analyses of the primary outcome, deaths

    Broad-band imaging and even imaging with a moderate bandpass (about 1 nm) provides a photon-rich environment, where frame selection (lucky imaging) becomes a helpful tool in image restoration, allowing us to perform a cost-benefit analysis on how to design observing sequences for imaging with high spatial resolution in combination with real-time correction provided by an adaptive optics (AO) system. This study presents high-cadence (160 Hz) G-band and blue continuum image sequences obtained with the High-resolution Fast Imager (HiFI) at the 1.5-meter GREGOR solar telescope, where the speckle-masking technique is used to restore images with nearly diffraction-limited resolution. The HiFI employs two synchronized large-format and high-cadence sCMOS detectors. The median filter gradient similarity (MFGS) image-quality metric is applied, among others, to AO-corrected image sequences of a pore and a small sunspot observed on 2017 June 4 and 5. A small region of interest, which was selected for fast-imaging performance, covered these contrast-rich features and their neighborhood, which were part of Active Region NOAA 12661. Modifications of the MFGS algorithm uncover the field- and structure-dependency of this image-quality metric. However, MFGS still remains a good choice for determining image quality without a priori knowledge, which is an important characteristic when classifying the huge number of high-resolution images contained in data archives. In addition, this investigation demonstrates that a fast cadence and millisecond exposure times are still insufficient to reach the coherence time of daytime seeing. Nonetheless, the analysis shows that data acquisition rates exceeding 50 Hz are required to capture a substantial fraction of the best seeing moments, significantly boosting the performance of post-facto image restoration.

    The present study examined whether maternal diet and early infant feeding experiences relating to being breast-fed and complementary feeding influence the range of healthy foods consumed in later childhood. Data from four European birth cohorts were studied. Healthy Plate Variety Score (HPVS) was calculated using FFQ. HPVS assesses the variety of healthy foods consumed within and across the five main food groups. The weighted numbers of servings consumed of each food group were summed; the maximum score was 5. Associations between infant feeding experiences, maternal diet and the HPVS were tested using generalized linear models and adjusted for appropriate confounders. The British Avon Longitudinal Study of Parents and Children (ALSPAC), the French Etude des Déterminants pre et postnatals de la santé et du développement de L'Enfant study (EDEN), the Portuguese Generation XXI Birth Cohort and the Greek EuroPrevall cohort. Pre-school children and their mothers. The mean HPVS for each of the cohorts ranged from 2.3 to 3.8, indicating that the majority of children were not eating a full variety of healthy foods. Never being breast-fed or being breast-fed for a short duration was associated with lower HPVS at 2, 3 and 4 years of age in all cohorts. There was no consistent association between the timing of complementary feeding and HPVS. Mother's HPVS was strongly positively associated with child's HPVS but did not greatly attenuate the relationship with breast-feeding duration. Results suggest that being breast-fed for a short duration is associated with pre-school children eating a lower variety of healthy foods.

    Full Text Available The aim of this study was to determine the intake and food sources of potassium and the molar sodium:potassium (Na:K ratio in a sample of Australian pre-school children. Mothers provided dietary recalls of their 3.5 years old children (previous participants of Melbourne Infant Feeding Activity and Nutrition Trial. The average daily potassium intake, the contribution of food groups to daily potassium intake, the Na:K ratio, and daily serves of fruit, dairy, and vegetables, were assessed via three unscheduled 24 h dietary recalls. The sample included 251 Australian children (125 male, mean age 3.5 (0.19 (SD years. Mean potassium intake was 1618 (267 mg/day, the Na:K ratio was 1.47 (0.5 and 54% of children did not meet the Australian recommended adequate intake (AI of 2000 mg/day for potassium. Main food sources of potassium were milk (27%, fruit (19%, and vegetable (14% products/dishes. Food groups with the highest Na:K ratio were processed meats (7.8, white bread/rolls (6.0, and savoury sauces and condiments (5.4. Children had a mean intake of 1.4 (0.75 serves of fruit, 1.4 (0.72 dairy, and 0.52 (0.32 serves of vegetables per day. The majority of children had potassium intakes below the recommended AI. The Na:K ratio exceeded the recommended level of 1 and the average intake of vegetables was 2 serves/day below the recommended 2.5 serves/day and only 20% of recommended intake. An increase in vegetable consumption in pre-school children is recommended to increase dietary potassium and has the potential to decrease the Na:K ratio which is likely to have long-term health benefits.

    Autism is associated with impairments that have life-time consequences for diagnosed individuals and a substantial impact on families. There is growing interest in early interventions for children with autism, yet despite the substantial economic burden, there is little evidence of the cost-effectiveness of such interventions with which to support resource allocation decisions. This study reports an economic evaluation of a parent-mediated, communication-focused therapy carried out within the Pre-School Autism Communication Trial (PACT). 152 pre-school children with autism were randomly assigned to treatment as usual (TAU) or PACT + TAU. Primary outcome was severity of autism symptoms at 13-month follow-up. Economic data included health, education and social services, childcare, parental productivity losses and informal care. Clinically meaningful symptom improvement was evident for 53 % of PACT + TAU versus 41 % of TAU (odds ratio 1.91, p = 0.074). Service costs were significantly higher for PACT + TAU (mean difference £4,489, p < 0.001), but the difference in societal costs was smaller and non-significant (mean difference £1,385, p = 0.788) due to lower informal care rates for PACT + TAU. Improvements in outcome generated by PACT come at a cost. Although this cost is lower when burden on parents is included, the cost and effectiveness results presented do not support the cost-effectiveness of PACT + TAU compared to TAU alone.

    How teachers manage class learning and interact with students affects students’ motivation and engagement. However, it could be that the effect of students’ representation of teaching quality on the students’ motivation varies between classes. Students from 90 classes participated in the study. We used multilevel random structural equation modeling to analyze whether the relationship of the students’ perception of teaching quality (as an indicator of the students’ mental representation) and students’ motivation varies between classes, and if this variability depends on the class assessment of teaching quality (as an indicator of teaching quality). The effect of teachers’ structure on the regression slope of student perception of student competence was .127. The effect of teachers’ autonomy support on the regression slope of student perception of student autonomy was .066. With this study we contribute a more detailed description of the relationship between teaching quality, competence and autonomy.

    Full Text Available The paper reviews original data obtained by the present authors, revealed in recent separate publications, describing specific procedures for high quality grey irons, and reflecting the forecast needs of the worldwide iron foundry industry. High power, medium frequency coreless induction furnaces are commonly used in electric melting grey iron foundries. This has resulted in low sulphur (1,500 °C, contributing to unfavourable conditions for graphite nucleation. Thin wall castings are increasingly produced by these electric melt shops with a risk of greater eutectic undercooling during solidification. The paper focused on two groups of grey cast irons and their specific problems: carbides and graphite morphology control in lower carbon equivalent high strength irons (CE=3.4%-3.8%, and austenite dendrite promotion in eutectic and slightly hypereutectic irons (CE=4.1%-4.5%, in order to increase their strength characteristics. There are 3 stages and 3 steps involving graphite formation, iron chemistry and iron processing that appear to be important. The concept in the present paper sustains a threestage model for nucleating flake graphite [(Mn,XS type nuclei]. There are three important groups of elements (deoxidizer, Mn/S, and inoculant and three technological stages in electric melting of iron (superheat, pre-conditioning of base iron, final inoculation. Attention is drawn to a control factor (%Mn x (%S ensuring it equals to 0.03 – 0.06, accompanied by 0.005wt.%–0.010wt.% Al and/or Zr content in inoculated irons. It was found that iron powder addition promotes austenite dendrite formation in eutectic and slightly eutectic, acting as reinforcement for the eutectic cells. But, there is an accompanying possible negative influence on the characteristics of the (Mn,XS type graphite nuclei (change the morphology of nuclei from polygonal compact to irregular polygonal, and therefore promote chill tendency in treated irons.

    Chickpea or gram (Cicer arietinum L.) is an important legume crop of Pakistan, grown on over one million hectares annually. The national average yield of the crop is very low (0.5 t/ha) and thus the country had to spent about 2 billion rupees ($ 50 million) on import of pulses. The main causes of low yield are non-availability of genetic sources for resistance to various diseases especially gram blight Ascochyta rabiei (Pass.) Lab., insect pest (Pod borer) and non-adoption of proper production technology by the farmers. This calls for earnest efforts of breeders to evolve high yielding and disease resistant varieties of chickpea for provision of quality seeds to the farming community to increase production of this important crop. Seeds of a highly blight susceptible variety '6153' were irradiated at 200 Gy dose of gamma radiation in 1985 and the promising mutant line CMN-446-4 was selected in M3 generation on the basis of disease resistance, greater number of pods and better plant type. After confirmation of its resistance to blight in M 4 and M 5 , the mutant line was evaluated in various trials at different locations. In the advanced and zonal yield trials during 1993-95, the line CMN-446-4 produced the highest grain yield of 2,600 kg/ha as compared to the rest of the mutants and varieties. The line was also evaluated in the chickpea national uniform yield trial, conducted on over 11 locations in the country during 1993-94. In this trial, the mutant line ranked 3rd by producing an average yield of 1,528 kg/ha as compared to the two check varieties 'Punjab-91' (1,316 kg/ha) and 'Paidar-91' (1,391 kg/ha). The mutant line CMN-446-4 is moderately resistant to gram blight, highly resistant to stored pest (pulse beetle), contains 25.3% more protein as compared to the parental variety 6153 and is also better in nitrogen fixing capacity.The proposal for release of the mutant line CMN-446-4 as a new variety under the name 'NIFA-95' for general cultivation in the rainfed

  5. Physics and quality assurance for high dose rate brachytherapy

    Anderson, Lowell L.

    1995-01-01

    Purpose: To review the physical aspects of high dose rate (HDR) brachytherapy, including commissioning and quality assurance, source calibration and dose distribution measurements, and treatment planning methods. Following the introduction of afterloading in brachytherapy, development efforts to make it 'remote' culminated in 1964 with the near-simultaneous appearance of remote afterloaders in five major medical centers. Four of these machines were 'high dose rate', three employing 60Co and one (the GammaMed) using a single, cable-mounted 192Ir source. Stepping-motor source control was added to the GammaMed in 1974, making it the precursor of modern remote afterloaders, which are now suitable for interstitial as well as intracavitary brachytherapy by virtue of small source-diameter and indexer-accessed multiple channels. Because the 192Ir sources currently used in HDR remote afterloaders are supplied at a nominal air-kerma strength of 11.4 cGy cm2 s-1 (10 Ci), are not collimated in clinical use, and emit a significant fraction (15%) of photons at energies greater than 600 keV, shielding and facility design must be undertaken as carefully and thoroughly as for external beam installations. Licensing requirements of regulatory agencies must be met with respect both to maximum permissible dose limits and to the existence and functionality of safety devices (door interlocks, radiation monitors, etc.). Commissioning and quality assurance procedures that must be documented for HDR remote afterloading relate to (1) machine, applicator, guide-tube, and facility functionality checks, (2) source calibration, (3) emergency response readiness, (4) planning software evaluation, and (5) independent checks of clinical dose calculations. Source calibration checks must be performed locally, either by in-air measurement of air kerma strength or with a well ionization chamber calibrated (by an accredited standards laboratory) against an in-air measurement of air kerma strength for the

    BACKGROUND: Recent studies found an association between a long waiting time to pregnancy (TTP) and reduced probability of twinning and a reduced dizygotic (DZ) twinning rate in subfertile men. However, it remains unsolved whether semen quality is associated with twin offspring. We therefore studied...... the semen quality in a group of fathers of naturally conceived twins. METHODS: In this study, 37 fathers of DZ twins and 15 fathers of monozygotic (MZ) twins participated, and 349 normal fertile men served as a reference group. All men delivered a semen sample, underwent a physical examination and completed...... points higher than the reference group (P semen quality than the reference group, which supports...

  9. High throughput electrospinning of high-quality nanofibers via an aluminum disk spinneret

    Science.gov (United States)

    Zheng, Guokuo

    In this work, a simple and efficient needleless high throughput electrospinning process using an aluminum disk spinneret with 24 holes is described. Electrospun mats produced by this setup consisted of fine fibers (nano-sized) of the highest quality while the productivity (yield) was many times that obtained from conventional single-needle electrospinning. The goal was to produce scaled-up amounts of the same or better quality nanofibers under variable concentration, voltage, and the working distance than those produced with the single needle lab setting. The fiber mats produced were either polymer or ceramic (such as molybdenum trioxide nanofibers). Through experimentation the optimum process conditions were defined to be: 24 kilovolt, a distance to collector of 15cm. More diluted solutions resulted in smaller diameter fibers. Comparing the morphologies of the nanofibers of MoO3 produced by both the traditional and the high throughput set up it was found that they were very similar. Moreover, the nanofibers production rate is nearly 10 times than that of traditional needle electrospinning. Thus, the high throughput process has the potential to become an industrial nanomanufacturing process and the materials processed by it may be used as filtration devices, in tissue engineering, and as sensors.

    Bernal stacked (AB stacked) bilayer graphene is of significant interest for functional electronic and photonic devices due to the feasibility to continuously tune its band gap with a vertical electrical field. Mechanical exfoliation can be used to produce AB stacked bilayer graphene flakes but typically with the sizes limited to a few micrometers. Chemical vapor deposition (CVD) has been recently explored for the synthesis of bilayer graphene but usually with limited coverage and a mixture of AB and randomly stacked structures. Herein we report a rational approach to produce large-area high quality AB stacked bilayer graphene. We show that the self-limiting effect of graphene growth on Cu foil can be broken by using a high H2/CH4 ratio in a low pressure CVD process to enable the continued growth of bilayer graphene. A high temperature and low pressure nucleation step is found to be critical for the formation of bilayer graphene nuclei with high AB stacking ratio. A rational design of a two-step CVD process is developed for the growth of bilayer graphene with high AB stacking ratio (up to 90 %) and high coverage (up to 99 %). The electrical transport studies demonstrated that devices made of the as-grown bilayer graphene exhibit typical characteristics of AB stacked bilayer graphene with the highest carrier mobility exceeding 4,000 cm2/V·s at room temperature, comparable to that of the exfoliated bilayer graphene.

    Expected quality is believed to be one of the most important factors that influence consumers' intention to purchase food. The present study seeks to explore the concept of pork meat expected quality and compare it with self-stated consumer intention to purchase pork meat. The aim is attempted by means of a field research conducted in Greece, following a conjoint analytic procedure. Results show that quality expectations comply with intention to buy pork, in many aspects. However, several differences have been identified. More specifically, country of origin and marbling appear to be more important for respondents' purchase decisions than they are for their quality evaluations, while the opposite appears to be true for price. Finally, socio-demographic factors such as gender, level of education, place of purchase and consumption habits seem to influence perceptions. Copyright © 2012 Elsevier Ltd. All rights reserved.

  1. Manufacturing High-Quality Carbon Nanotubes at Lower Cost

    Science.gov (United States)

    Benavides, Jeanette M.; Lidecker, Henning

    2004-01-01

    A modified electric-arc welding process has been developed for manufacturing high-quality batches of carbon nanotubes at relatively low cost. Unlike in some other processes for making carbon nanotubes, metal catalysts are not used and, consequently, it is not necessary to perform extensive cleaning and purification. Also, unlike some other processes, this process is carried out at atmospheric pressure under a hood instead of in a closed, pressurized chamber; as a result, the present process can be implemented more easily. Although the present welding-based process includes an electric arc, it differs from a prior electric-arc nanotube-production process. The welding equipment used in this process includes an AC/DC welding power source with an integral helium-gas delivery system and circulating water for cooling an assembly that holds one of the welding electrodes (in this case, the anode). The cathode is a hollow carbon (optionally, graphite) rod having an outside diameter of 2 in. (approximately equal to 5.1 cm) and an inside diameter of 5/8 in. (approximately equal to 1.6 cm). The cathode is partly immersed in a water bath, such that it protrudes about 2 in. (about 5.1 cm) above the surface of the water. The bottom end of the cathode is held underwater by a clamp, to which is connected the grounding cable of the welding power source. The anode is a carbon rod 1/8 in. (approximately equal to 0.3 cm) in diameter. The assembly that holds the anode includes a thumbknob- driven mechanism for controlling the height of the anode. A small hood is placed over the anode to direct a flow of helium downward from the anode to the cathode during the welding process. A bell-shaped exhaust hood collects the helium and other gases from the process. During the process, as the anode is consumed, the height of the anode is adjusted to maintain an anode-to-cathode gap of 1 mm. The arc-welding process is continued until the upper end of the anode has been lowered to a specified height

    2012-01-01

    A case study has been performed which involved the full chain assessment from policy drivers to health effect quantification of lead exposure through locally produced food on loss of IQ in pre-school children at the population level across the EU-27, including monetary valuation of the estimated health impact. Main policy scenarios cover the period from 2000 to 2020 and include the most important Community policy developments expected to affect the environmental release of lead (Pb) and corresponding human exposure patterns. Three distinct scenarios were explored: the emission situation based on 2000 data, a business-as-usual scenario (BAU) up to 2010 and 2020 and a scenario incorporating the most likely technological change expected (Most Feasible Technical Reductions, MFTR) in response to current and future legislation. Consecutive model calculations (MSCE-HM, WATSON, XtraFOOD, IEUBK) were performed by different partners on the project as part of the full chain approach to derive estimates of blood lead (B-Pb) levels in children as a consequence of the consumption of local produce. The estimated B-Pb levels were translated into an average loss of IQ points/child using an empirical relationship based on a meta-analysis performed by Schwartz (1994). The calculated losses in IQ points were subsequently further translated into the average cost/child using a cost estimate of €10.000 per loss of IQ point based on data from a literature review. The estimated average reduction of cost/child (%) for all countries considered in 2010 under BAU and MFTR are 12.16 and 18.08% as compared to base line conditions, respectively. In 2020 the percentages amount to 20.19 and 23.39%. The case study provides an example of the full-chain impact pathway approach taking into account all foreseeable pathways both for assessing the environmental fate and the associated human exposure and the mode of toxic action to arrive at quantitative estimates of health impacts at the individual and

    Full Text Available Background Recently, parenting programs to address behavioural and emotional problems associated with child maltreatment in developing countries have received much attention. There is a paucity of literature on effective parent education interventions in the local context of Pakistan. This study aimed to assess the feasibility of offering a 6-week parenting program for mothers of pre-school children attending family health centres (FHCs in Karachi, the largest metropolitan city of Pakistan. Methods A pilot quasi-experimental trial was conducted. Two FHCs were selected, one as the intervention and the second as the control. A total of 57 mothers of pre-school children (n = 30 intervention; n = 27 control participated in this study. Mothers in the intervention group received SOS Help for parents module, while mothers in the control group received information about routine childcare. A parenting scale (PS was administered before the program was implemented and repeated 2 weeks after the program was completed in both groups. Statistical analysis was performed to compare participants’ attributes. Descriptive analysis was conducted to compare pre- and post-test mean scores along with standard deviation for parenting subscales in the intervention and control groups. Results A total of 50 mothers (n = 25 intervention; n = 25 control completed the 6-week program. Attrition was observed as 5/30 (17% in the intervention arm and 2/27 (2% in the control arm. Mothers commonly reported the burden of daily domestic and social responsibilities as the main reason for dropping out. Furthermore, the majority of participants in the control group recommended increasing the duration of weekly sessions from 1 to 1.5 hours, thereby decreasing the program period from 6 to 4 weeks. Mothers in intervention group reported substantial improvement in parenting skills as indicated by mean difference in their pre- and post-test scores for laxness and over

  4. Numerical determination of injector design for high beam quality

    International Nuclear Information System (INIS)

    Boyd, J.K.

    1985-01-01

    The performance of a free electron laser strongly depends on the electron beam quality or brightness. The electron beam is transported into the free electron laser after it has been accelerated to the desired energy. Typically the maximum beam brightness produced by an accelerator is constrained by the beam brightness deliverd by the accelerator injector. Thus it is important to design the accelerator injector to yield the required electron beam brightness. The DPC (Darwin Particle Code) computer code has been written to numerically model accelerator injectors. DPC solves for the transport of a beam from emission through acceleration up to the full energy of the injector. The relativistic force equation is solved to determine particle orbits. Field equations are solved for self consistent electric and magnetic fields in the Darwin approximation. DPC has been used to investigate the beam quality consequences of A-K gap, accelerating stress, electrode configuration and axial magnetic field profile

    Presently, most of the laser beam quality measurement system collimates the optical path manually with low efficiency and low repeatability. To solve these problems, this paper proposed a new collimated method to improve the reliability and accuracy of the measurement results. The system accuracy controlled the position of the mirror to change laser beam propagation direction, which can realize the beam perpendicularly incident to the photosurface of camera. The experiment results show that the proposed system has good repeatability and the measuring deviation of M2 factor is less than 0.6%.

    Coproduction of DnaK/DnaJ in Escherichia coli enhances solubility but promotes proteolytic degradation of their substrates, minimizing the yield of unstable polypeptides. Higher eukaryotes have orthologs of DnaK/DnaJ but lack the linked bacterial proteolytic system. By coexpression of DnaK and DnaJ in insect cells with inherently misfolding-prone recombinant proteins, we demonstrate simultaneous improvement of soluble protein yield and quality and proteolytic stability. Thus, undesired side effects of bacterial folding modulators can be avoided by appropriate rehosting in heterologous cell expression systems. PMID:19820142

    The effort over more than a decade to establish the semantic web [Berners-Lee et. al., 2001] has received a major boost in recent years through the Open Government movement. Governments around the world are seeking technical solutions to enable more open and transparent access to Public Sector Information (PSI) they hold. Existing technical protocols and data standards tend to be domain specific, and so limit the ability to publish and integrate data across domains (health, environment, statistics, education, etc.). The web provides a domain-neutral platform for information publishing, and has proven itself beyond expectations for publishing and linking human-readable electronic documents. Extending the web pattern to data (often called Web 3.0) offers enormous potential. The semantic web applies the basic web principles to data [Berners-Lee, 2006]: using URIs as identifiers (for data objects and real-world 'things', instead of documents) making the URIs actionable by providing useful information via HTTP using a common exchange standard (serialised RDF for data instead of HTML for documents) establishing typed links between information objects to enable linking and integration Leading examples of 'linked data' for publishing PSI may be found in both the UK (http://data.gov.uk/linked-data) and US (http://www.data.gov/page/semantic-web). The Bureau of Meteorology (BoM) is Australia's national meteorological agency, and has a new mandate to establish a national environmental information infrastructure (under the National Plan for Environmental Information, NPEI [BoM, 2012a]). While the initial approach is based on the existing best practice Spatial Data Infrastructure (SDI) architecture, linked-data is being explored as a technological alternative that shows great promise for the future. We report here the first trial of government linked-data in Australia under data.gov.au. In this initial pilot study, we have taken BoM's new high-quality reference surface

    Full Text Available Introduction & Objective: The aim of the present study was to evaluate the effects of food guide pyramid education on the knowledge of 5 to 6 year-old children in kindergarten in Shiraz, Iran, using play and show methods. Materials & Methods: 62 children, 5 to 6 years old, were selected from one of the districts of Shiraz pre-schools by random cluster sampling. Subjects were divided into two groups. One group was educated by show and the other group by play and drawings. However, in both groups, they were educated using the same subjects about the food guide pyramid. The results were recorded by some tests before and after the intervention and were analyzed by the SPSS software using two sample t-test and Mann-Whitney U-test. Results: In both groups, after being taught about food guide pyramids, their knowledge about the number of food groups and recognizing them were improved (P<0.001. In both groups, their knowledge about the priority of any good and bad snack improved after the intervention, but this increase was significant only in the drawing and playing group (P<0.05. Conclusion: In a happy environment, children can gain good capacities for nutrition education and also playing and drawing can provide good interactions. Therefore, this method can be a useful choice for informing the children.

    Prevalence, incidence and seasonal variation of Cryptosporidium and Giardia duodenalis were studied over a 12-month period in 100 children from four pre-schools in Kafue, Zambia. Questionnaire data and a single stool sample were collected monthly from each child. Samples were processed using...... a commercial kit (Meridian Diagnostics Inc., USA) and oo(cysts) visualised by immunofluorescence microscopy. Cryptosporidium was detected in 30.7% (241/786; 95% CI = 27.5-33.9) while G. duodenalis was detected in 29.0% (228/786; 95% CI = 25.8-32.2). A total of 86% experienced one or more episodes...... of cryptosporidiosis while 75% had giardiasis. Cumulative incidence per 100 children was 75.4 for Cryptosporidium and 49.0 for G. duodenalis. Both infections were significantly more common in the wet compared to the dry season (34.8%, 162/466 vs. 24.7%, 79/320, P = 0.003 and 35.2%, 164/466 vs. 20.0%, 64/320, P

    Pre-school children placed in local authority care show elevated rates of mental health disorders when compared to the general population. This study investigated risk factors for mental health disorders relating to the period prior to entering care and while in care. A representative sample of 43 children in care aged 0-72 months in an inner London borough underwent comprehensive multidimensional assessments. Presence of emotional, behavioural, attachment and adaptive disorders was ascertained. Exposure to two pre-placement risk factors and six placement risk factors was compared between children with and without a disorder. A total of 26 children (60.5%) had at least one mental health disorder. The two pre-placement risk factors, multiple types of maltreatment and entry into care after the age of 6 months, were both significantly associated with mental health disorders. The three placement risk factors of sudden placement moves, multiple placement moves and child-carer alienation showed a significant association with mental health disorders. There was a strong correlation between the number of risk factors and the number of co-morbid mental health disorders per child (r = .67, p school mental health. © The Author(s) 2014.

    Full Text Available Abstract This study investigated the effects of a vitamin and mineral fortified powder product supplemented with inulin, on the iron and vitamin A status of 110 pre-schools childrens in Viçosa, MG, Brazil. The 2 to 5-year-old children were submitted to anthropometric (weight and height, biochemical (erythrocytes, hemoglobin, mean corpuscular volume – MCV, mean corpuscular hemoglobin - MCH, serum iron, ferritin and serum retinol and dietary (direct food weighing, 24 h recall, and food intake record evaluations, at the beginning and at the end of a 45-day intervention. The supplement (30 g was provided daily as part of the afternoon snack, diluted in 100 mL of water, 5 times/week and it supplied 30% of the recommended daily doses of iron, zinc, copper and vitamins A and C. Dietary and biochemical data was compared by the Wilcoxon test, and anthropometric data by the paired t-test. Values of z-scores for weight and height, erythrocytes, hemoglobin, MCV, MCH and ferritin were significantly higher after intervention; no change was observed in serum retinol. The prebiotic-containing supplement significantly increased the intake of energy, macro and micronutrients, and was effective in improving the iron and anthropometric status.

    Daytime deficits in children with sleep disordered breathing (SDB) are theorized to result from hypoxic insult to the developing brain or fragmented sleep. Yet, these do not explain why deficits occur in primary snorers (PS). The time course of slow wave EEG activity (SWA), a proxy of homeostatic regulation and cortical maturation, may provide insight. Clinical and control subjects (N=175: mean age 4.3±0.9 y: 61% male) participated in overnight polysomnography (PSG). Standard sleep scoring and power spectral analyses were conducted on EEG (C4/A1; 0.5-sleep stages and respiratory parameters. Repeated-measures ANCOVA evaluated group differences in the time course of SWA. Four groups were classified: controls (OAHI ≤ 1 event/h; no clinical history); PS (OAHI ≤ 1 event/h; clinical history); mild OSA (OAHI=1-5 events/h); and moderate to severe OSA (MS OSA: OAHI>5 events/h). Group differences were found in the percentage of time spent in NREM Stages 1 and 4 (psleep pressure but impaired restorative sleep function in pre-school children with SDB, providing new insights into the possible mechanism for daytime deficits observed in all severities of SDB.

    To examine whether physicians who sought and received Bridges to Excellence (BTE) recognition performed better than similar physicians on a standardized set of population-based performance measures. Cross-sectional comparison of performance data. Using a claims dataset of all commercially insured members from 6 health plans in Massachusetts, we examined population-based measures of quality and resource use for physicians recognized by the BTE programs Physician Office Link and Diabetes Care Link, compared with nonrecognized physicians in the same specialties. Differences in performance were tested using generalized linear models. Physician Office Link-recognized physicians performed significantly better than their nonrecognized peers on measures of cervical cancer screening, mammography, and glycosylated hemoglobin testing. Diabetes Care Link-recognized physicians performed significantly better on all 4 diabetes process measures of quality, with the largest differences observed in microalbumin screening (17.7%). Patients of Physician Office Link-recognized physicians had a significantly greater percentage of their resource use accounted for by evaluation and management services (3.4%), and a smaller percentage accounted for by facility (-1.6%), inpatient ancillary (-0.1%), and nonmanagement outpatient services (-1.0%). After adjustment for patient age and sex, and case mix, Physician Office Link-recognized physicians had significantly fewer episodes per patient (0.13) and lower resource use per episode (dollars 130), but findings were mixed for Diabetes Care Link-recognized physicians. Our findings suggest that the BTE approach to ascertaining physician quality identifies physicians who perform better on claims-based quality measures and primary care physicians who use a less resource-intensive practice style.

    For all these reasons, in some cases we could not count 100 nucleoids per slide. However, we decided to include the subjects in the final analysis of the results only if at least 60 nucleoids per subject (about 30 per slide, in 2 slides per subject were found [21]. Besides primary DNA damage, the RESPIRA study investigated micronucleus frequency in epithelial buccal cells of the same children as another biomarkers of early effects. The results of this test [22] showed a weak, but significant, association between MN frequency and concentration of air pollutants, such as PM10, PM2.5 and NO2. Moreover, MN level in the children of Brescia was higher than usually found among children living in areas with low or medium-high levels of air pollution.

    Full Text Available Most lecturers and professors involved in teaching School Management and Education Management courses have been engaged in developing some innovative actions to improve the training quality that we offer to students in the Pedagogy degree at the Autonomous University of Barcelona. These actions are aimed at increasing co-ordination among the teaching staff when designing and implementing the course curricula. Co-ordination meetings, exchanges of teaching experiences, discussions about what, how and when to teach the different contents, in which courses and at what level, methodological issues pointed out through technical description cards or the elaboration of study cases to be solved have become the basis of relevant actions during the last academic years. This paper explains each one of them, and provides useful information about the theoretical background, the process carried out, some of the results obtained, the output and the tools created.

    Full Text Available The paper presents the influence of the type of furnace charging melting, refining and modification silumins 226 and 231 on the porosity and microstructure of castings. It was shown that in order to reduce or eliminate the porosity of the castings is necessary to the refining ECOSAL-AL113 of liquid silumin both in the melting furnace, and in the ladle and an additional nitrogen, in the heat furnace modified and refining with nitrogen. To control the effects of refining and modifying the TDA method was used. It was found that based on crystal- lization curve can be qualitatively assess the gas porosity of the castings. In order to control and quality control silumins author developed a computer program using the method of TDA, which sets out: Rm, A5, HB and casting porosity P and the concentration of hydrogen in them. The program also informs the technological procedures to be performed for liquid silumin improper preparation.

    Accurate and efficient developmental screening measures are critical for early identification of developmental problems; however, few reliable and valid tests are available in Korea as well as other countries outside the USA. The Ages and Stages Questionnaires (ASQ) was chosen for study with young children in Korea. The ASQ was translated into Korean and necessary cross-cultural adaptations were made. The translated version was then distributed and completed by 3220 parents of young children between the ages of 4 months and 5 years. Reliability was studied including domain correlations, internal consistency, and performance of identification cut-off scores for the Korean population. Rasch analyses including tests of Differential Item Functioning, contrasting Korean and US samples were also performed. In general, internal consistency of the Korean ASQ was high, with overall correlations 0.75 for communication, 0.85 for gross motor, 0.74 for fine motor, 0.72 for problem solving, and 0.65 for personal-social. Validity, including concurrent validity, also had strong evidence. Mean scores of children on the Korean translation of the ASQ and the US normative sample were generally similar. Rasch analyses indicated the majority of items functioned similarly across the Korean sample. In general, the ASQ was translated with cultural appropriateness in mind and functioned as a valid and reliable parent-completed screening test to assist in early identification of young children with developmental delays. Further research is needed to confirm these results with a larger and more diverse Korean sample.

    Objective Malnutrition in children pervades all aspects of their health, growth, cognitive and social development and can lead to irreversible and lifelong effects. We examine the prevalence and determinants of malnutrition in children under 5 in the Ghanaian population. Methods Using data from the latest available Ghana Demographic and Health Survey (GDHS), we estimated and compared prevalence of malnutrition in children among the different subgroups of the population. We used multivariable logistic regression to identify potential factors associated with childhood malnutrition in Ghana. Results Overall, 35.6 % (95 % CI: 33.6, 37.6) of Ghanaian children under 5 years of age suffer from some form of malnutrition. Specifically, 27.5 % (95 % CI: 25.1, 28.7), 13.8 % (95 % CI: 12.5, 15.3), 8.9 % (95 % CI: 7.8, 10.2) were stunted, underweight and wasted, respectively. Results from the logistic regression indicate that gender and age of the child, educational and nutritional status of the mother, and financial status of the household are risk factors associated with childhood malnutrition in Ghana. Conclusions for Practice In view of the observed high rate of malnutrition among Ghanaian children despite the interventions that have been in place since the 1990s, there is a need for increased awareness and improved targeted interventions as well as knowledge translation tools including extensive education on infant and young child feeding practices.

The early evaluation of attention in childhood is essential for their school and career success in the future. The aim of this study was to design, development and investigation of psychometric properties (content, face and convergent validity and test-retest and internal consistency reliability of the computer - based sustained visual attention test (SuVAT for healthy preschool children aged 4-6 with their special needs. Methods: This study was carried out in two stages: in the first stage computerbased SuVAT in two versions original and parallel were developed. Then the test-retest and internal consistency reliability using intra-class correlation and Cronbach’s alpha coefficients respectively were examined; Face validity was calculated through ideas gathering from 10 preschool children and content validity evaluated using CVI and CVR method and convergent validity of SuVAT with CPT was assessed using Pearson correlation. Results: The developed test showed a good content and faces validity, and also had excellent test-retest reliability. In addition, the assessment of internal consistency indicated the high internal consistency of the test (Cronbach’s alpha=0.869. SuVAT and CPT test demonstrated a positive correlation upon the convergent validity testing. Conclusion: SuVAT with good reliability and validity could be used as an acceptable sustained attention assessment in preschool children.

    Full Text Available It is quite well known that excessive body fat in children is interpreted as a marker of inhibited physical activity and motor performance. This study aimed to establish whether severe impairment of fundamental motor skills (defined as performance under 5th centile of norms will be significantly more frequently identified in pre-schoolers age 3-6 years with amount of body fat higher than 85th centile of norms. Research sample consisted of 496 (females=241, males=255 pre-schoolers selected from specific district of Prague, Czech Republic. The MABC-2 was used for the assesment fundamental motor skills. Equations for body fat estimation in children identified 35.8% children with body fat˃85th centile of norms, 61.7% within 15th–85th centile, and 2.5% of children˂15th centile of norms. Results revealed that children whose body fat was higher than 85th centile of norms or lower than 15th centile had double the frequency of severe motor problems. Interestingely on the other hand we found no signficant differences in the frequency of high above average performances˃90th centile in MABC-2 between fat 8.4% and non fat children 10.7%. We suggest that amount of body fat is not a clear predictor for the degree of fundamental motor skills.

    Rearing a child with a developmental disability is associated with increased parental stress. Theories of stress and adjustment and bi-directional theories of child development suggest that parenting could influence these negative outcomes. Relationships between parenting approaches and stress in parents of children with developmental disabilities (DD) (N = 53) were examined across two age groups, 3-5 years and 9-11 years and compared with a contrast group of typically developing children (TD) (N = 60). Measures used were the Parenting Stress Index-Short Form and Rickel and Biasatti's modification of Block's Child Rearing Practices Report, classified into Baumrind's parenting styles using Reitman and Gross's method. Parents in the older DD group used Authoritative parenting less than parents in the younger DD group, while the opposite developmental pattern was seen in the TD group. Multivariate analysis of variance showed a significant group x parenting style interaction for Parental Distress, Parent-Child Dysfunctional Interaction and Difficult Child. Stress measures were higher for the DD group and seemed to be associated with Authoritative parenting approaches, an effect that was not observed in the TD group. Findings suggest that the well-established effect of group on stress may be moderated by parenting style. Authoritative parenting may be highly stressful for parents of children with DD to implement, resulting in a decrease in its use across the two age groups.

    1995-01-01

    This paper interweaves some suggestions for developing actively cooled plasma-facing components (PFCs) for future fusion devices, with supporting examples taken from the design, fabrication and operation of Tore Supra's Phase III outboard pump limiter (OPL). This actively cooled midplane limiter, designed for heat and particle removal during long-pulse operation, has been operated under essentially thermally steady state conditions. Testing to identify braze flaws, analysis of the impact of joining flaws on the thermal-hydraulic performance of the OPL, and the extensive calorimetry and IR thermography used to confirm and update safe operating limits for power handling of the OPL are reviewed. This experience suggests that, for PFCs in future fusion devices, flaw-tolerant designs are possible; analyses of the impacts of flaws on performance can provide criteria for quality assurance; and validating appropriate methods of inspection for such flaws early in the design development of PFCs is prudent. The need for in-service monitoring is also discussed. (orig.)

    In the past, health management in Geneva's six post-trial prisons had been variable and inconsistent. In 2008, the unit of penitentiary medicine of the Geneva University Hospitals was mandated to re-organize and provide health care at all six prison facilities. The specific aim of this paper is to outline the example as a practical solution to some of the common challenges in unifying the structure and process of health services across multiple small facilities, while meeting European prison health and local quality standards. Geneva's post-trial prisons are small and close to one another in geographical proximity - ideal conditions for the construction of a health mobile team (HMT). This multidisciplinary mobile team operated like a community ambulatory care model; it was progressively launched in all prison facilities in Geneva. The authors incorporated an implementation strategy where health providers partnered with prison and community stakeholders in the health delivery model's development and adaption process. The model's strategic initiatives are described along the following areas, in light of other international prison health activity and prior care models: access to a health care professional, equivalence of care, patient consent, confidentiality, humanitarian interventions, and professional competence and independence. From the perspective of the HMT members, the authors provide the "lessons learned" through this experience, especially to providers who are working on prison health services reform and coordination improvement. The paper particularly stresses the importance of partnering with community health stakeholders and prison staff, a key component to the approach.

  1. Bust economics: foragers choose high quality habitats in lean times

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available In environments where food resources are spatially variable and temporarily impoverished, consumers that encounter habitat patches with different food density should focus their foraging initially where food density is highest before they move to patches where food density is lower. Increasing missed opportunity costs should drive individuals progressively to patches with lower food density as resources in the initially high food density patches deplete. To test these expectations, we assessed the foraging decisions of two species of dasyurid marsupials (dunnarts: Sminthopsis hirtipes and S. youngsoni during a deep drought, or bust period, in the Simpson Desert of central Australia. Dunnarts were allowed access to three patches containing different food densities using an interview chamber experiment. Both species exhibited clear preference for the high density over the lower food density patches as measured in total harvested resources. Similarly, when measuring the proportion of resources harvested within the patches, we observed a marginal preference for patches with initially high densities. Models analyzing behavioral choices at the population level found no differences in behavior between the two species, but models analyzing choices at the individual level uncovered some variation. We conclude that dunnarts can distinguish between habitat patches with different densities of food and preferentially exploit the most valuable. As our observations were made during bust conditions, experiments should be repeated during boom times to assess the foraging economics of dunnarts when environmental resources are high.

    Plants sharing a single light environment on a spaceship with a human being and bearing a decorative function should look as natural and attractive as possible. And consequently they can be illuminated only with white light with a high color rendering index. Can lighting optimized for a human eye be effective and appropriate for plants? Spectrum-based effects have been compared under artificial lighting of plants by high-pressure sodium lamps and general-purpose white LEDs. It has been shown that for the survey sample phytochrome photo-equilibria does not depend significantly on the parameters of white LED light, while the share of phytoactive blue light grows significantly as the color temperature increases. It has been revealed that yield photon flux is proportional to luminous efficacy and increases as the color temperature decreases, general color rendering index Ra and the special color rendering index R14 (green leaf) increase. General-purpose white LED lamps with a color temperature of 2700 K, Ra > 90 and luminous efficacy of 100 lm/W are as efficient as the best high-pressure sodium lamps, and at a higher luminous efficacy their yield photon flux per joule is even bigger in proportion. Here we show that demand for high color rendering white LED light is not contradictory to the agro-technical objectives.

    The National Institute for Health and Care Excellence (NICE) was established in 1999 to provide evidence-based guidance. The task of producing guidance by reviewing primary research data and using an advisory committee to develop evidence-based recommendations, is not straightforward. Guidance production is, however, less challenging than the task of putting evidence-based recommendations into practice.NICE is very sensitive to this challenge as, since 1999, over 1500 pieces of NICE guidance have been published. A number of pieces of guidance relate to heart disease, including pharmaceutical agents, new medical technologies and clinical guidelines. Examples include guidelines on acute heart failure and atrial fibrillation, and advice on technologies including edoxaban and implantable cardioverter defibrillators.The research evidence is clear that a change in practice rarely comes about as a result of simply disseminating guidance on best practice. Simple dissemination is particularly ineffective if the guidance has not been produced by a well-respected, credible organisation. It is also clear from the literature that implementation is more successful when more than one approach is taken, and when there is alignment between efforts at organisational, local and national levels.At an organisational level, there should be support from the Board for quality improvement, with ongoing measurement of progress. Resources should be provided for targeted change programmes, particularly where new guidance suggests improvements are required. A systematic process for putting change in place should include identifying barriers to change, agreeing interventions to overcome the barriers and drive forward improvement and planning for implementation and evaluation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    There is a paucity of studies evaluating targeted obesity prevention interventions in pre-school children. We conducted a randomized controlled trial to evaluate the efficacy of a parent-based obesity prevention intervention for pre-schoolers - MEND (Mind, Exercise, Nutrition … Do It!) 2-4 on child diet, eating habits, physical activity/sedentary behaviours, and body mass index (BMI). Parent-child dyads attended 10 weekly 90-min workshops relating to nutrition, physical activity and behaviours, including guided active play and healthy snack time. Assessments were conducted at baseline, immediately post-intervention, and 6 and 12 months post-intervention; child intake of vegetables, fruit, beverages, processed snack foods, fussiness, satiety responsiveness, physical activity, sedentary behaviour and neophobia were assessed via parent proxy report. Parent and child height and weight were measured. Two hundred one parent-child dyads were randomized to intervention (n = 104) and control (n = 97). Baseline mean child age was 2.7 (standard deviation [SD] 0.6) years, and child BMI-for-age z-score (World Health Organization) was 0.66 (SD 0.88). We found significant positive group effects for vegetable (P = 0.01) and snack food (P = 0.03) intake, and satiety responsiveness (P = 0.047) immediately post-intervention. At 12 months follow-up, intervention children exhibited less neophobia (P = 0.03) than controls. Future research should focus on additional strategies to support parents to continue positive behaviour change. ACTRN12610000200088. © 2015 World Obesity.

    Childhood obesity is increasing. However, little is known about the changes in di-etary factors and supportive facilities associated with childhood obesity. We aimed to document the changes in various dietary factors and supportive facilities and their associations with obesity among pre-school children. Among 42,531 children 4-5 years old, recruited between 2004 and 2013 in the Jiax-ing Birth Cohort, we examined the changes in the prevalence of various dietary factors and supportive facilities and overweight/obesity over 10 years. We used logistic regression to investigate the cross-sectional association between these factors and childhood overweight/obesity risk, adjusting for potential confounders. The prevalence of childhood overweight/obesity increased steadily from 11.8% (boy: 14.8%; girl: 9%) during 2004-2005 to 18% (boy: 21.4%%; girl: 15%) during 2012-2013. The prevalence of meal/snack frequency 3 times /day decreased substantially from 23% during 2004-2005 to 8% during 2012-2013, with more children having 5 times /day: from 32% to 45.6%. Children with a fair/bad appetite, compared with those with a good appetite, had a 45% (OR: 0.55; 95% CI: 0.49, 0.62) lower risk of overweight/obesity. Children with a meal frequency >=6 times/day (compared with 3 times/day) had a 0.12 (95% CI: 0.03, 0.2) higher BMI-z-score. The prevalence of childhood overweight/obesity has increased substantially within a decade in southeast China. A better appetite and greater eating frequency were associated with the increased prevalence.

    The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being. © The Author(s) 2013.

    (i) To explore dental, school and family perspectives of an oral health promotion (OHP) initiative to improve access for pre-school children in deprived communities; (ii) to develop a model of roles and responsibilities for OHP in community settings. Semi-structured focus groups (n = 6) with dental practice staff (n = 24), and semi-structured interviews with school staff (n = 9) and parents and children (n = 4) who were involved in an OHP initiative for pre-school children. Framework analysis was applied to identify themes. Themes were used to develop a model of roles and responsibilities for OHP, based on the WHO Planning and evaluating health promotion model. Respondents subscribed to a community-based approach to improving access to dental services for pre-school children in deprived areas, with an emphasis on shared responsibility and communication. In addition to macro-level actions in directing health policy and services, commissioners were held responsible for investing in micro-level actions, such as funding OHP training and involving parents, and meso-level actions such as reducing barriers to access. The model we have developed builds on WHO recommendations on health promotion to identify the key roles and responsibilities that should be incorporated into further initiatives in OHP.

    CERN Multimedia

    During the past seven years, the DREAM collaboration has systematically investigated all factors that determine and limit the precision with which the properties of hadrons and jets can be measured in calorimeters. Using simultaneous detection of the deposited energy and the Cerenkov light produced in hadronic shower development ${(dual}$ ${readout}$), the fluctuations in the electromagnetic shower fraction could be measured event by event their effects on signal linearity, response function and energy resolution eliminated. Detailed measurement of the time structure of the signals made it possible to measure the contirbutions of nuclear evaporation neutrons to the signals and thus reduce the effects of fluctuations in "invisible energy". We are now embarking on the construction of a full-scale calorimeter which incorporates all these elements and which should make it possible to measure the four-vectors of both electrons, hadrons and jets with very high precision, in an instrument that can be simply calibrat...

    Nuclear industry achieves about 20% of its turnover with the export of equipment and services but nuclear trade is submitted to specific constrains like non-proliferation policies. According to IAEA the world capacity of nuclear power is expected to double allowing the development of emerging countries while reducing CO_2 emissions. The French commercial offer focuses on the high-end market with the EPR reactor and an intermediate power range reactor ATMEA-1 designed with MHI (Mitsubishi Heavy Industries). AREVA is the unique world operator able to master the entire chain of spent fuel reprocessing thanks to the La Hague plant. In the framework of the rebuilding of the French nuclear industry, discussions are ongoing to achieve partnerships with foreign partners in exchange of shares in AREVA and AREVA NP. Today's main challenges of AREVA are to reduce EPR cost, to speed EPR construction and to benefit fully of the move into the digital age. (A.C.)

    NOAA curates a vast treasure trove of environmental data, but one that is sometimes not easily accessed, especially for education, outreach, and media purposes. Traditional data portals in NOAA require extensive knowledge of the specific names of observation platforms, models, and analyses, along with nomenclature for variable outputs. A new website and web mapping service (WMS) from NOAA attempts to remedy such issues. The NOAA View data imagery portal provides a seamless entry point into data from across the agency: satellite, models, in-situ analysis, etc. The system provides the user with ability to browse, animate, and download high resolution (e.g., 4,000 x 2,000 pixel) imagery, Google Earth, and even proxy data files. The WMS architecture also allows the resources to be ingested into other software systems or applications.

    The amount of food waste generated from modern societies is increasing, which has imposed a tremendous pressure on its treatment and disposal. Food waste should be treated as a valuable resource rather than waste, and turning it into fish feeds would be a viable alternative. This paper attempts to review the feasibility of using food waste to formulate feed pellets to culture a few freshwater fish species, such as grass carp, grey mullet, and tilapia, under polyculture mode (growing different species in the same pond). These species occupy different ecological niches, with different feeding modes (i.e., herbivorous, filter feeding, etc.), and therefore all the nutrients derived from the food waste could be efficiently recycled within the ecosystem. The problems facing environmental pollution and fish contamination; the past and present situation of inland fish culture (focusing on South China); upgrade of food waste based feed pellets by adding enzymes, vitamin-mineral premix, probiotics (yeast), prebiotics, and Chinese medicinal herbs into feeds; and potential health risks of fish cultivated by food waste based pellets are discussed, citing some local examples. It can be concluded that appropriate portions of different types of food waste could satisfy basic nutritional requirements of lower trophic level fish species such as grass carp and tilapia. Upgrading the fish pellets by adding different supplements mentioned above could further elevated the quality of feeds, leading to higher growth rates, and enhanced immunity of fish. Health risk assessments based on the major environmental contaminants (mercury, PAHs and DDTs) in fish flesh showed that fish fed food waste based pellets are safer for consumption, when compared with those fed commercial feed pellets.

    Thorium as a nuclear fuel has received renewed interest, because of its widespread availability and the good irradiation performance of Th and mixed (Th,U) oxide compounds as fuels in nuclear power systems. Early HTGR development employed thorium together with high-enriched uranium (HEU). After 1980, HTGR fuel systems switched to low-enriched uranium (LEU). After completing fuel development for the AVR and the THTR with BISO coated particles, the German program expanded its efforts utilizing thorium and HEU TRISO coated particles in advanced HTGR concepts for process heat applications (PNP) and direct-cycle electricity production (HHT). The combination of a low-temperature isotropic (LTI) inner and outer pyrocarbon layers surrounding a strong, stable SiC layer greatly improved manufacturing conditions and the subsequent contamination and defective particle fractions in production fuel elements. In addition, this combination provided improved mechanical strength and a higher degree of solid fission product retention, not known previously with high-temperature isotropic (HTI) BISO coatings. The improved performance of the HEU (Th, U)O{sub 2} TRISO fuel system was successfully demonstrated in three primary areas of development: manufacturing, irradiation testing under normal operating conditions, and accident simulation testing. In terms of demonstrating performance for advanced HTGR applications, the experimental failure statistic from manufacture and irradiation testing are significantly below the coated particle requirements specified for PNP and HHT designs at the time.

    The effects of high- versus low-quality child care during 2 developmental periods (infant-toddlerhood and preschool) were examined using data from the National Institute of Child Health and Human Development Study of Early Child Care. Propensity score matching was used to account for differences in families who used different combinations of child care quality during the 2 developmental periods. Findings indicated that cognitive, language, and preacademic skills prior to school entry were highest among children who experienced high-quality care in both the infant-toddler and preschool periods, somewhat lower among children who experienced high-quality child care during only 1 of these periods, and lowest among children who experienced low-quality care during both periods. Irrespective of the care received during infancy-toddlerhood, high-quality preschool care was related to better language and preacademic outcomes at the end of the preschool period; high-quality infant-toddler care, irrespective of preschool care, was related to better memory skills at the end of the preschool period.

  5. An approach to high speed ship ride quality simulation

    The high speeds attained by certain advanced surface ships result in a spectrum of motion which is higher in frequency than that of conventional ships. This fact along with the inclusion of advanced ride control features in the design of these ships resulted in an increased awareness of the need for ride criteria. Such criteria can be developed using data from actual ship operations in varied sea states or from clinical laboratory experiments. A third approach is to simulate ship conditions using measured or calculated ship motion data. Recent simulations have used data derived from a math model of Surface Effect Ship (SES) motion. The model in turn is based on equations of motion which have been refined with data from scale models and SES of up to 101 600-kg (100-ton) displacement. Employment of broad band motion emphasizes the use of the simulators as a design tool to evaluate a given ship configuration in several operational situations and also serves to provide data as to the overall effect of a given motion on crew performance and physiological status.

    We report on a scanning confocal Raman spectroscopy study investigating the strain-uniformity and the overall strain and doping of high-quality chemical vapour deposited (CVD) graphene-based heterostuctures on a large number of different substrate materials, including hexagonal boron nitride (hBN), transition metal dichalcogenides, silicon, different oxides and nitrides, as well as polymers. By applying a hBN-assisted, contamination free, dry transfer process for CVD graphene, high-quality heterostructures with low doping densities and low strain variations are assembled. The Raman spectra of these pristine heterostructures are sensitive to substrate-induced doping and strain variations and are thus used to probe the suitability of the substrate material for potential high-quality graphene devices. We find that the flatness of the substrate material is a key figure for gaining, or preserving high-quality graphene.

    In large, mostly English-speaking countries, where the "critical mass" of scientists working in different subfields of science is achieved, the peer review system may be sufficient to assess the quality of scientific research. However, in smaller countries, outside the Anglo-American circle, it is important to introduce different systems to identify research of high quality. In Poland, a parametric system for assessing the quality of research has been introduced. It was largely based on the impact factor of scientific journals. While the use of this indicator to assess research quality is highly questionable, the implementation of the system in the Polish reality is even worse. Therefore it is important to change and improve the system currently used by the Ministry of Science and Higher Education to both evaluate and, more importantly, finance science in Poland. Here, a system based on three factors, i.e. the impact factor, the institutional h-index, and the institutional number of citations, is proposed. The scientific quality of institutions in Division VI: Medical Sciences of the Polish Academy of Sciences were evaluated and the results were compared with the existing system. Moreover, a method to identify high-quality researchers and institutions at the national level based on the quantity of highly cited papers is shown. Additionally, an attempt to identify the highest quality Polish research on an international level is proposed. This is based on the number of individual citations, the individual h-index, the number of publications, and the priority of the discovery.

    The present work was undertaken to study the effect of pearling duration, soaking time, steaming duration and drying temperature on the quality of sesame seeds and mechanically extracted partially defatted sesame cake. On the basis of quality attributes i.e. high protein, low crude fibre, low residual oil and low oxalic acid, the optimum process parameters were selected. The combination of 20 min of pearling duration, 15 min of soaking, 15 min of steaming at 100 kPa pressure and drying at 50 °C yielded high quality partially defatted protein rich sesame flour as compared to untreated defatted sesame flour. The developed high quality partially defatted protein rich sesame flour may be used in various food applications as a vital ingredient to increase the nutritional significance of the prepared foodstuffs.

    Full Text Available Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has high levels of phenolic compounds. High amounts of polyphenolic and polysaccharide compounds in plants could be causing problems in RNA extraction procedures.  To avoid these problems, a simple and efficient method can be used based on cetyltrimethylammonium bromide (CTAB extraction buffer and lithium chloride for extraction of high quality RNA from different parts of hazelnut plant. Using this method, a high-quality RNA sample (light absorbed in the A260/A280 was 2.04

    Full Text Available Investigamos a relação entre fatores de aprendizagem social, acessados via questionários, e os comportamentos agressivos e lúdicos de meninos pré-escolares, através de observação direta durante o recreio. Os participantes foram 15 meninos com idades entre quatro e seis anos, da cidade de Goiânia, GO, Brasil. Uma análise multivariada de variância indicou efeitos significativos de modelos de agressividade em casa nas taxas de agressão durante o brincar. Crianças expostas a punições físicas abusivas, brigas entre adultos e programas violentos de TV apresentaram mais agressões reais. Meninos que relataram brincar com armas de brinquedo em casa não apresentaram mais agressões reais do que os que relataram o contrário, mas apresentaram maior proporção de agressões de faz-de-conta. Os resultados também indicaram que quanto mais modelos agressivos em casa, maior a incidência de comportamentos agressivos.We investigated the interaction between social learning factors measured by questionnaires and aggressive and playful behaviors of pre-school children, through direct observation during their playful break time. The subjects were 15 boys between four and six years old who were enrolled in a non-profit child care center in Goiânia-GO, Brazil. A multivariate analysis of variance indicated significant effects of aggressive models at home on aggression levels during playful behavior. Children exposed to abusive physical punishment, adult fighting and violent TV programs engaged in more episodes of aggression during playful breaks. Boys who reported to play with toy guns at home did not engage in aggressive behavior more often than those who did not, but they displayed a higher proportion of pretended aggression. Results also indicated that aggressive behavior becomes more frequent as the number of aggressive models at home increases.

    The quality and quantity of RNA are critical for successful downstream transcriptome-based studies such as microarrays and RNA sequencing (RNA-Seq). RNA isolation from woody plants, such as Pistacia vera, with very high amounts of polyphenols and polysaccharides is an enormous challenge. Here, we describe a highly efficient protocol that overcomes the limitations posed by poor quality and low yield of isolated RNA from pistachio and various recalcitrant woody plants. The key factors that resulted in a yield of 150 μg of high quality RNA per 200 mg of plant tissue include the elimination of phenol from the extraction buffer, raising the concentration of β-mercaptoethanol, long time incubation at 65 °C, and nucleic acid precipitation with optimized volume of NaCl and isopropyl alcohol. Also, the A260/A280 and A260/A230 of extracted RNA were about 1.9-2.1and 2.2-2.3, respectively, revealing the high purity. Since the isolated RNA passed highly stringent quality control standards for sensitive reactions, including RNA sequencing and real-time PCR, it can be considered as a reliable and cost-effective method for RNA extraction from woody plants.

    The objective of this paper was to demonstrate application of quality function deployment in analysing effects of high power ultrasound on quality properties of apple juices and nectars. In order to develop a quality function deployment model, joint with instrumental analysis of treated samples, a field survey was performed to identify consumer preferences towards quality characteristics of juices/nectar. Based on field research, the three most important characteristics were 'taste' and 'aroma' with 28.5% of relative absolute weight importance, followed by 'odour' (16.9%). The quality function deployment model showed that the top three 'quality scores' for apple juice were treatments with amplitude 90 µm, 9 min treatment time and sample temperature 40 °C; 60 µm, 9 min, 60 °C; and 90 µm, 6 min, 40 °C. For nectars, the top three were treatments 120 µm, 9 min, 20 °C; 60 µm, 9 min, 60 °C; and A2.16 60 µm, 9 min, 20 °C. This type of quality model enables a more complex measure of large scale of different quality parameters. Its simplicity should be understood as its practical advantage and, as such, this tool can be a part of design quality when using novel preservation technologies. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    The aim of this quasi-experimental study was to examine whether high-volume percutaneous coronary intervention (PCI) operators still maintain high volume and quality of outcomes when they moved to lower volume hospitals. Systematic reviews have indicated that high-volume PCI operators and hospitals have higher quality outcomes. However, little is known on whether high PCI volume and high quality outcomes are mainly due to operator characteristics (i.e., skill and experience) and is portable across organizations or whether it is due to hospital characteristics (i.e., equipment, team, and management system) and is less portable. We used Taiwan National Health Insurance claims data 2000-2012 to identify 98 high-volume PCI operators, 10 of whom moved from one hospital to another during the study period. We compared the PCI volume, risk-adjusted mortality ratio, and major adverse cardiovascular event (MACE) ratio before and after moving. Of the 10 high-volume operators who moved, 6 moved from high- to moderate- or low-volume hospitals, with median annual PCI volumes (interquartile range) of 130 (117-165) in prior hospitals and 54 (46-84) in subsequent hospitals (the hospital the operator moved to), and the remaining 4 moved from high to high-volume hospitals, with median annual PCI volumes (interquartile range) of 151 (133-162) in prior hospitals and 193 (178-239) in subsequent hospitals. No significant differences were observed in the risk-adjusted mortality ratios and MACE ratios between high-volume operators and matched controls before and after moving. High-volume operators cannot maintain high volume when they moved from high to moderate or low-volume hospitals; however, the quality of care is maintained. High PCI volume and high-quality outcomes are less portable and more hospital bound. © 2017 Wiley Periodicals, Inc.

    2016-01-01

    To summarize current high-quality studies evaluating the effect and efficacy of resident duty hours reforms (DHRs) on patient safety and resident education and well-being. The authors searched PubMed and Medline in August 2012 and again in May 2013 for literature (1987-2013) about the effects of DHRs. They assessed the quality of articles using the Medical Education Research Study Quality Instrument (MERSQI) scoring system. They considered randomized controlled trials (RCTs), partial RCTs, and all studies with a MERSQI score ≥ 14 to be "high-quality" methodology studies. A total of 72 high-quality studies met inclusion criteria. Most studies showed no change or slight improvement in mortality and complication rates after DHRs. Resident well-being was generally improved, but there was a perceived negative impact on education (knowledge acquisition, skills, and cognitive performance) following DHRs. Eleven high-quality studies assessed the impact of DHR interventions; all reported a neutral to positive impact. Seven high-quality studies assessed costs associated with DHRs and demonstrated an increase in hospital costs. The results of most studies that allow enough time for DHR interventions to take effect suggest a benefit to patient safety and resident well-being, but the effect on the quality of training remains unknown. Additional methodologically sound studies on the impact of DHRs are necessary. Priorities for future research include approaches to optimizing education and clinical proficiency and studies on the effect of intervention strategies on both education and patient safety. Such studies will provide additional information to help improve duty hours policies.

    Montano, Diego

    2016-08-05

    The present study proposes a set of quality requirements to management practices by taking into account the empirical evidence on their potential effects on health, the systemic nature of social organisations, and the current conceptualisations of management functions within the framework of comprehensive quality management systems. Systematic reviews and meta-analyses focusing on the associations between leadership and/or supervision and health in occupational settings are evaluated, and the core elements of an ISO 9001 standardisation approach are presented. Six major occupational health requirements to high-quality management practices are identified pertaining to communication processes, organisational justice, role clarity, decision making, social influence processes and management support. It is concluded that the quality of management practices may be improved by developing a quality management system of management practices that ensures not only conformity to product but also to occupational safety and health requirements. Further research may evaluate the practicability of the proposed approach.

    2015-01-01

    Local backlight dimming is a technology aiming at both saving energy and improving visual quality on television sets. As the rendition of the image is specified locally, the numerical signal corresponding to the displayed image needs to be computed through a model of the display. This simulated...... signal can then be used as input to objective quality metrics. The focus of this paper is on determining which characteristics of locally backlit displays influence quality assessment. A subjective experiment assessing the quality of highly contrasted videos displayed with various local backlight......-dimming algorithms is set up. Subjective results are then compared with both objective measures and objective quality metrics using different display models. The first analysis indicates that the most significant objective features are temporal variations, power consumption (probably representing leakage...

    Clinical trials have reported a low time in therapeutic range (TTR) in patients with atrial fibrillation treated with both warfarin andamiodarone. These trials included centers and countries with both high and low TTRs. What is the impact of amiodarone on the TTR in a single, high-quality anticoagulation clinic? TTR was assessed in amiodarone and nonamiodarone-treated patients from a University anticoagulation clinic. Baseline characteristics between patients ever-taking or never-taking amiodarone were similar, except more amiodarone patients were smokers (19.5 vs. 6.1%, P = 0.0031). The TTR calculated from 8901international normalized ratios (INRs) in 249 nonamiodarone patients with a mean follow-up of 34 ± 20 months (mean INR 36 ± 18) was 66 ± 16.6% compared with 61.3 ± 16.2% (P = 0.111) from 1455 INRs in 41 amiodarone-treated patients with a mean follow-up of 28 ± 20 months (mean INR 35 ± 22). Factors associated with a low TTR were male sex (P = 0.0013), smoker (P = 0.0048), and amiodarone use (P = 0.0374). A second on-treatment analysis, in which the TTR was calculated only during amiodarone therapy, resulted in similar findings; however, amiodarone did not emerge as a predictor of a low TTR. In 11 patients, the TTR prior to amiodarone (54.5 ± 22.2%) was not significantly different in the first 3 months (54.6 ± 33.4%) or after 3 months (67.2 ± 33.7%) of amiodarone. In a single high-quality anticoagulation center, anticoagulation quality, as measured by the TTR, can be comparable in amiodarone and nonamiodarone-treated patients.

    High-efficient and large-scale production of high-quality CNT dispersions is necessary for meeting the future needs to develop various CNT-based electronic devices. Herein, we have designed novel processing protocols by combining conventional ultrasonication process with a new microfluidization technique to produce high-quality SWCNT dispersions with improved processing efficiency. To judge the quality of SWCNT dispersions, one critical factor is the degree of exfoliation, which could be quantified by both geometrical dimension of the exfoliated nanotubes and percentage of individual tubes in a given dispersion. In this paper, the synergistic effect of the combined protocols was systematically investigated through evaluating SWCNT dispersions with newly developed characterization techniques, namely preparative ultracentrifuge method (PUM) and simultaneous Raman scattering and photoluminescence spectroscopy (SRSPL). The results of both techniques draw similar conclusions that as compared with either of the processes operated separately, a low-pass microfluidization followed by a reasonable duration of ultrasonication could substantially improve the processing efficiency to produce high-quality SWCNT dispersions with averaged particle length and diameter as small as ~600 and ~2 nm, respectively.Graphical abstract.

    Full Text Available The author of this paper wants to pay attention to the utmost problems of treatment and pre-school upbringing, from several points of view ( health, social, educational, economic, normative etc., that are related to the establishment of the primary conditions and suppositions for successful organization of protection and rehabilitation of these children.Children with developmental difficulties are quite a complex problem of the family, society and professional problem. The complexity and the burden of this problem are seen through the type and level of impairment, through the number of such children, as in providing financial, personnel and other conditions that are needed for successful protection and treatment.Taking into consideration the number of these children, in the paper is given the prognosis according to some percentages used for the whole population by ON and WHO. It is considered that 5-7 % are children with developmental difficulties at pre-school period. because the main topic at this Symposium is early treatment and pre- school upbringing, the early age is taken for the mentioned percentage. According to this, in our country there are about 19.000 children from 0-9 years of age, if this percentage of 6 % is applied from the total number of children at that age, that shows in the latest census of the population in the R. of Macedonia in 1994 , that there are 313.908 children. This number shows the gravity of the problem that is elaborated in this paper. The author stresses that the complexity of this problem increases if we take into consideration the present conditions according to the range of these children with early treatment and preschool upbringing, as apart of the whole system of rehabilitation.The complete treatment, i.e. the rehabilitation of children with developmental difficulties presents the unity of all the provisions and proceedings that are necessary to be undertaken to eliminate or reduce to the minimum

    Techniques to build a high-quality cut-off wall have been developed for storage facilities of low-level radioactive waste (LLW) as an emergency measures to prevent leakages. The cut-off wall is highly impermeable, nucleid-adsorptive and have long-term durability. Electrophoresis is used to form impermeable membrane of bentonite as main features of the cut-off wall. First of all, laboratory tests have been conducted to study ways of building barriers on site and to collect data on the barriers properties. Afterwards, on-site construction tests of a high-quality cut-off wall have been carried out. In this paper, we describe the process and results on the studies of the high-quality cut-off wall using electrophoresis

    Traditionally, radiographic film has been used to verify high-dose-rate brachytherapy source position accuracy by co-registering autoradiographic and diagnostic images of the associated applicator. Filmless PACS-based clinics that do not have access to radiographic film and wet developers may have trouble performing this quality assurance test in a simple and practical manner. We describe an alternative method for quality assurance using radiochromic-type film. In addition to being easy and practical to use, radiochromic film has some advantages in comparison with traditional radiographic film when used for HDR brachytherapy quality assurance

    Myrciaria dubia is a main source of vitamin C for people in the Amazon region. Molecular studies of M. dubia require high-quality total RNA from different tissues. So far, no protocols have been reported for total RNA isolation from leaves of this species. The objective of this research was to develop protocols for extracting high-quality total RNA from leaves of M. dubia. Total RNA was purified following two modified protocols developed for leaves of other species (by Zeng and Yang, and by Reid et al.) and one modified protocol developed for fruits of the studied species (by Silva). Quantity and quality of purified total RNA were assessed by spectrophotometric and electrophoretic analysis. Additionally, quality of total RNA was evaluated with reverse-transcription polymerase chain reaction (RT-PCR). With these three modified protocols we were able to isolate high-quality RNA (A260nm/A280nm >1.9 and A260nm/A230nm >2.0). Highest yield was produced with the Zeng and Yang modified protocol (384±46µg ARN/g fresh weight). Furthermore, electrophoretic analysis showed the integrity of isolated RNA and the absence of DNA. Another proof of the high quality of our purified RNA was the successful cDNA synthesis and amplification of a segment of the M. dubia actin 1 gene. We report three modified protocols for isolation total RNA from leaves of M. dubia. The modified protocols are easy, rapid, low in cost, and effective for high-quality and quantity total RNA isolation suitable for cDNA synthesis and polymerase chain reaction.

    High quality beam generation project based on High-Tech Research Center Project, which has been approved by Ministry of Education, Culture, Sports, Science and Technology in 1999, has been conducted by advance research institute for science and engineering, Waseda University. In the project, laser photo-cathode RF-gun has been selected for the high quality electron beam source. RF cavities with low dark current, which were made by diamond turning technique, have been successfully manufactured. The low emittance electron beam was realized by choosing the modified laser injection technique. The obtained normalized emmitance was about 3 m.mrad at 100 pC of electron charge. The soft x-ray beam generation with the energy of 370 eV, which is in the energy region of so-called water window, by inverse Compton scattering has been performed by the collision between IR laser and the low emmitance electron beams.

    The current literature suggests deficiencies in the quality of acute pain management among general medical inpatients. The aim of this qualitative study is to identify potential barriers to high-quality acute pain management among general medical inpatients at an urban academic medical center during a 2-year period. Data are collected using retrospective chart reviews, survey questionnaires, and semistructured, open-ended interviews of 40 general medical inpatients who have experienced pain during their hospitalization. Our results confirm high prevalence and disabling impacts of pain and significant patient- and provider-related barriers to high-quality acute pain management. We also identify unique system-related barriers such as time delay and pain management culture. Efforts to improve the pain management experience of general medical inpatients will need to address all these barriers. © The Author(s) 2014.

    The present study was performed to assess the quality of Potentilla fruticosa L. sampled from distinct regions of China using high performance liquid chromatography (HPLC) fingerprinting coupled with a suite of chemometric methods. For this quantitative analysis, the main active phytochemical compositions and the antioxidant activity in P. fruticosa were also investigated. Considering the high percentages and antioxidant activities of phytochemicals, P. fruticosa samples from Kangding, Sichuan were selected as the most valuable raw materials. Similarity analysis (SA) of HPLC fingerprints, hierarchical cluster analysis (HCA), principle component analysis (PCA), and discriminant analysis (DA) were further employed to provide accurate classification and quality estimates of P. fruticosa. Two principal components (PCs) were collected by PCA. PC1 separated samples from Kangding, Sichuan, capturing 57.64% of the variance, whereas PC2 contributed to further separation, capturing 18.97% of the variance. Two kinds of discriminant functions with a 100% discrimination ratio were constructed. The results strongly supported the conclusion that the eight samples from different regions were clustered into three major groups, corresponding with their morphological classification, for which HPLC analysis confirmed the considerable variation in phytochemical compositions and that P. fruticosa samples from Kangding, Sichuan were of high quality. The results of SA, HCA, PCA, and DA were in agreement and performed well for the quality assessment of P. fruticosa. Consequently, HPLC fingerprinting coupled with chemometric techniques provides a highly flexible and reliable method for the quality evaluation of traditional Chinese medicines.

    Mass rearing tsetse flies Glossina spp. is dependent on the sustained availability of a high quality blood diet. In any mass rearing facility, the logistics for obtaining sterile, high quality fresh blood is challenging. An added complication is the influence of potential chemical, physical and microbiological elements present in the blood of donors, as well as contamination during collection, handling and storage. Research at the Agricultural Research Council - Onderstepoort Veterinary institute (ARC-OVI) is directed towards the development of quality control procedures for the supply of the in vitro diet used to maintain productive colonies of Glossina brevipalpis Newstead and Glossina austeni Newstead. Factors that may influence the blood diet, e.g. defibrination, feeding times, collection of blood in anticoagulants, treatment of blood with taste stimuli, repeated freezing and thawing of blood, effect of bovine growth hormones, and also a preference for bovine or porcine blood were tested. A 25 day bioassay was used to determine the effects of these factors on tsetse survival and reproduction. Defibrination of the blood for 10 to 15 minutes gave the best results for both species. It was found that G. brevipalpis should be fed three times per week for 5 minutes each time, and G. austeni three times per week for 10 minutes. Heparin, acid citrate dextrose (ACD), citric acid, citrate phosphate dextrose adenine (CPDA) and a combination of sodium citrate and citric acid were effective anticoagulants in the blood diets of G. brevipalpis and G. austeni. Blood treated with inosine triphosphate (ITP) gave the highest quality factor (QFC) values for both G. austeni and G. brevipalpis. Repeated freezing and thawing of blood definitely affects pupal production negatively; G. brevipalpis especially produced significantly smaller pupae. A premixed diet of equal amounts of bovine and porcine blood was found to be best suited for G. brevipalpis, and for G. austeni a mixture of

  13. Different Polar Metabolites and Protein Profiles between High- and Low-Quality Japanese Ginjo Sake.

    Directory of Open Access Journals (Sweden)

    Kei Takahashi

    Full Text Available Japanese ginjo sake is a premium refined sake characterized by a pleasant fruity apple-like flavor and a sophisticated taste. Because of technical difficulties inherent in brewing ginjo sake, off-flavors sometimes occur. However, the metabolites responsible for off-flavors as well as those present or absent in higher quality ginjo sake remain uncertain. Here, the relationship between 202 polar chemical compounds in sake identified using capillary electrophoresis coupled with time-of-flight mass spectrometry and its organoleptic properties, such as quality and off-flavor, was examined. First, we found that some off-flavored sakes contained higher total amounts of metabolites than other sake samples. The results also identified that levels of 2-oxoglutaric acid and fumaric acid, metabolites in the tricarboxylic acid cycle, were highly but oppositely correlated with ginjo sake quality. Similarly, pyridoxine and pyridoxamine, co-enzymes for amino transferase, were also highly but oppositely correlated with ginjo sake quality. Additionally, pyruvic acid levels were associated with good quality as well. Compounds involved in the methionine salvage cycle, oxidative glutathione derivatives, and amino acid catabolites were correlated with low quality. Among off-flavors, an inharmonious bitter taste appeared attributable to polyamines. Furthermore, protein analysis displayed that a diversity of protein components and yeast protein (triosephosphate isomerase, TPI leakage was linked to the overall metabolite intensity in ginjo sake. This research provides insight into the relationship between sake components and organoleptic properties.

    Pérez, A G; Sanz, C

    2001-05-01

    The effect of high-oxygen atmospheres on strawberry flavor was studied. Strawberry fruits (Fragariax ananassa Duch. cv. Camarosa) were stored at 8 degrees C in four different atmospheres: air, 5% O(2)/20% CO(2), 80% O(2)/20% CO(2), and 90% O(2)/10% CO(2). Changes in several quality parameters were evaluated. Atmospheres combining high O(2) and high CO(2) were the most effective in preventing fungal growth and enhancing strawberry firmness. Other quality parameters such as color, titrable acidity, sugars and organic acids distribution, off-flavor development, and aroma were only mildly affected by superatmospheric O(2) levels. After one week of storage, unexpected high contents of off-flavor related compounds were found in the 80% O(2)/20% CO(2) and 90% O(2)/10% CO(2) atmospheres. Evidence of an altered ester biosynthesis was also found in fruits stored under these high-O(2) atmospheres. Data obtained suggest that stress induced by high CO(2) and stress induced by high O(2) have an additive effect on strawberry flavor alteration.

    Full Text Available Abstract Background Exome sequencing using next-generation sequencing technologies is a cost efficient approach to selectively sequencing coding regions of human genome for detection of disease variants. A significant amount of DNA fragments from the capture process fall outside target regions, and sequence data for positions outside target regions have been mostly ignored after alignment. Result We performed whole exome sequencing on 22 subjects using Agilent SureSelect capture reagent and 6 subjects using Illumina TrueSeq capture reagent. We also downloaded sequencing data for 6 subjects from the 1000 Genomes Project Pilot 3 study. Using these data, we examined the quality of SNPs detected outside target regions by computing consistency rate with genotypes obtained from SNP chips or the Hapmap database, transition-transversion (Ti/Tv ratio, and percentage of SNPs inside dbSNP. For all three platforms, we obtained high-quality SNPs outside target regions, and some far from target regions. In our Agilent SureSelect data, we obtained 84,049 high-quality SNPs outside target regions compared to 65,231 SNPs inside target regions (a 129% increase. For our Illumina TrueSeq data, we obtained 222,171 high-quality SNPs outside target regions compared to 95,818 SNPs inside target regions (a 232% increase. For the data from the 1000 Genomes Project, we obtained 7,139 high-quality SNPs outside target regions compared to 1,548 SNPs inside target regions (a 461% increase. Conclusions These results demonstrate that a significant amount of high quality genotypes outside target regions can be obtained from exome sequencing data. These data should not be ignored in genetic epidemiology studies.

    To gain a deeper understanding of how primary care (PC) practices belonging to different models manage resources to provide high-quality care. Multiple-case study embedded in a cross-sectional study of a random sample of 37 practices. Three regions of Quebec. Health care professionals and staff of 5 PC practices. Five cases showing above-average results on quality-of-care indicators were purposefully selected to contrast on region, practice size, and PC model. Data were collected using an organizational questionnaire; the Team Climate Inventory, which was completed by health care professionals and staff; and 33 individual interviews. Detailed case histories were written and thematic analysis was performed. The core common feature of these practices was their ongoing effort to make trade-offs to deliver services that met their vision of high-quality care. These compromises involved the same 3 areas, but to varying degrees depending on clinic characteristics: developing a shared vision of high-quality care; aligning resource use with that vision; and balancing professional aspirations and population needs. The leadership of the physician lead was crucial. The external environment was perceived as a source of pressure and dilemmas rather than as a source of support in these matters. Irrespective of their models, PC practices' pursuit of high-quality care is based on a vision in which accessibility is a key component, balanced by appropriate management of available resources and of external environment expectations. Current PC reforms often create tensions rather than support PC practices in their pursuit of high-quality care. Copyright© the College of Family Physicians of Canada.

    For high brightness direct diode laser systems, it is of fundamental importance to improve the slow axis beam quality of the incorporated laser diodes regardless what beam combining technology is applied. To further advance our products in terms of increased brightness at a high power level, we must optimize the slow axis beam quality despite the far field blooming at high current levels. The later is caused predominantly by the built-in index step in combination with the thermal lens effect. Most of the methods for beam quality improvements reported in publications sacrifice the device efficiency and reliable output power. In order to improve the beam quality as well as maintain the efficiency and reliable output power, we investigated methods of influencing local heat generation to reduce the thermal gradient across the slow axis direction, optimizing the built-in index step and discriminating high order modes. Based on our findings, we have combined different methods in our new device design. Subsequently, the beam parameter product (BPP) of a 10% fill factor bar has improved by approximately 30% at 7 W/emitter without efficiency penalty. This technology has enabled fiber coupled high brightness multi-kilowatt direct diode laser systems. In this paper, we will elaborate on the methods used as well as the results achieved.

  18. Microstructural and Material Quality Effects on Rolling Contact Fatigue of Highly Elastic Intermetallic Ball Bearings

    2016-01-01

    Rolling element bearings made from highly-elastic intermetallic materials (HIM)s, such as 60NiTi, are under development for applications that require superior corrosion and shock resistance. Compared to steel, intermetallics have been shown to have much lower rolling contact fatigue (RCF) stress capability in simplified 3-ball on rod (ASTM STP 771) fatigue tests. In the 3-ball tests, poor material quality and microstructural flaws negatively affect fatigue life but such relationships have not been established for full-scale 60NiTi bearings. In this paper, 3-ball-on-rod fatigue behavior of two quality grades of 60NiTi are compared to the fatigue life of full-scale 50mm bore ball bearings made from the same materials. 60NiTi RCF rods with material or microstructural flaws suffered from infant mortality failures at all tested stress levels while high quality 60NiTi rods exhibited no failures at lower stress levels. Similarly, tests of full-scale bearings made from flawed materials exhibited early surface fatigue and through crack type failures while bearings made from high quality material did not fail even in long-term tests. Though the full-scale bearing test data is yet preliminary, the results suggest that the simplified RCF test is a good qualitative predictor of bearing performance. These results provide guidance for materials development and to establish minimum quality levels required for successful bearing operation and life.

    High hydrostatic pressure as a kind of non-thermal processing might maintain the quality of thermo-sensitive watermelon juice. So, the effect of high hydrostatic pressure treatment on enzymes and quality of watermelon juice was investigated. After high hydrostatic pressure treatment, the activities of polyphenol oxidase, peroxidase, and pectin methylesterase of juice decreased significantly with the pressure (P  0.05). No significant difference was observed in lycopene and total phenolics after high hydrostatic pressure treatment when compared to the control (P > 0.05). Cloudiness and viscosity increased with pressure (P  0.05). a*- and b*-value both unchanged after high hydrostatic pressure treatment (P > 0.05) while L*-value increased but the values had no significant difference among treated juices. Browning degree after high hydrostatic pressure treatment decreased with increase in pressure and treatment time (P hydrostatic pressure had little effect on color of juice. The results of this study demonstrated the efficacy of high hydrostatic pressure in inactivating enzymes and maintaining the quality of watermelon juice.

    No primary practice care model has been shown to be superior in achieving high-quality primary care. We aimed to identify the organizational characteristics of primary care practices that provide high-quality primary care. We performed a cross-sectional observational study involving a stratified random sample of 37 primary care practices from 3 regions of Quebec. We recruited 1457 patients who had 1 of 2 chronic care conditions or 1 of 6 episodic care conditions. The main outcome was the overall technical quality score. We measured organizational characteristics by use of a validated questionnaire and the Team Climate Inventory. Statistical analyses were based on multilevel regression modelling. The following characteristics were strongly associated with overall technical quality of care score: physician remuneration method (27.0; 95% confidence interval [CI] 19.0-35.0), extent of sharing of administrative resources (7.6; 95% CI 0.8-14.4), presence of allied health professionals (15.3; 95% CI 5.4-25.2) and/or specialist physicians (19.6; 95% CI 8.3-30.9), the presence of mechanisms for maintaining or evaluating competence (7.7; 95% CI 3.0-12.4) and average organizational access to the practice (4.9; 95% CI 2.6-7.2). The number of physicians (1.2; 95% CI 0.6-1.8) and the average Team Climate Inventory score (1.3; 95% CI 0.1-2.5) were modestly associated with high-quality care. We identified a common set of organizational characteristics associated with high-quality primary care. Many of these characteristics are amenable to change through practice-level organizational changes.
