Full Text Available The purpose of this research is to assess physical activity among pupils in primary schools in Novi Sad, aged 11 years. The sample consisted of 185 participants (90 boys and 95 girls. Data were collected through a questionnaire, and modified Beacke Q questionnaire was used. Physical activity related to school - physical education, sports and leisure were assessed. Frequencies were calculated for all data, and significance of differences in inclusion and type of physical activity of pupils by sex was determined by Chi-square test. In all three dimensions of physical activity, the significant differences between boys and girls (p ≤ 0.05 were established. Boys have a higher level of physical activity compared to girls. Regular attendance of physical education is high, but the class intensity is low, while girls exercise with yet lower intensity compared to the boys. Boys are more active in sports and the most common sports for them are: football and basketball, while for girls those are volleyball and tennis. Pupils involved in sports generally carry out their activities more than 4 hours per week and 9 months per year. Most of their leisure time pupils spend with computers and TV, boys spend more time in sports, while girls spend more time walking.

Full Text Available The article presents the results of a study of adaptive possibilities (social and psychological of pupils of the first form to the educational activities in secondary schools. Using the research methods, an one-year experiment was conducted: the pupils of the first forms of Kamjanets-Podilsky secondary schools № 13 and № 14 (73 boys and 87 girls were selected by the method of random sample. The study found that the living conditions of the 6-year-olds (due to the beginning of education in secondary school do not assist formation of adequate adaptation: at the beginning, the social and psychological adaptation correspond to the average level, and in the end – to the lowest one. Obtained results give reason to conclude that the learning activities in the first year of study negatively affects the adaptive possibilities of the first form pupils; it results in poor mental capacity and health of pupils.

The idea of this project is to put pupils in a teaching situation. Classes of teenagers go to primary schools and animate a science workshop. Junior pupils are separated in small groups and they attend two different sessions in the same half-day. The whole workshop consists of 4 sessions. Each session is organized with an activity (microscope observation, counting of chromosomes, drawing of a curve, etc.) in which senior pupils coach the younger, and ends with a debate or an assessment. The first experiment of this type of project was realized with a class of 14 to 15 year old pupils on the theme: How do your parents transmit your characteristics? The four sessions are attended in disorder but when knowledge of other sessions are necessary, senior pupils explain them at the beginning of the session. Junior pupils have a notebook to write their activities and to note their conclusions. Session 1: What did my father give to make me? Drawing and measuring microscopic observations of human spermatozoons. Conclusion: my father gave a spermatozoon which measures less than one mm long, this spermatozoon met my mother's egg and it made my first cell. Session 2: What does the program that made me look like? Microscope observation of blood cells, identification of chromosomes in the core. On microscope pictures, counting of chromosomes. Conclusion: My program is in each cell of my body, inside the core. Sometimes, in this core, we can observe short sticks that are called chromosomes. All human beings have the same number of chromosomes in their cells: 46. Session 3: Where do my chromosomes come from? Counting of chromosomes in spermatozoons or ovums and playing with sets of chromosomes to deduct sex of a baby. Conclusion: Daddy gave me 23 chromosomes and mummy gave me 23 chromosomes too. My program is then constituted from half of daddy's program and half of mummy's program. My brothers and sisters also have half and half, but not the same halves! Session 4: Where is the

Full Text Available Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity. The study involved 2 phenomena typical for the behavior of the human pupil: pupillary reflex and pupillary movements. The 1st phenomenon is related to the pupillary light reflex (PLR, which presents the results of physiological adaptation mechanisms of the human eye. The pupillary unrest index (PUI is an additional parameter referring to the tendency for instability of the pupil. Material and methods Indicators of these 2 mechanisms were assessed under the same experimental laboratory conditions. Assessment was conducted on a group of volunteers (N = 10 during 4 controlled series of measurements performed at night. Pupillary reflex parameters associated with PLR and pupillary unrest index (PUI were recorded using F²D Fit-For-Duty, a commercially available system made by AMTech Pupilknowlogy GmbH. Baseline pupil diameter, oscillations, reflex latency, maximum reaction time, pupil constriction time, pupil dilation time, and constriction amplitude were recorded. Results As a result of the study, we were able to demonstrate correlation and confirm the usefulness of PLR and PST methods in the assessment of sleep deprivation. Parameters of PLR that may indicate human fatigue were identified. The effect of light impulse sequences on the dynamics of pupillary reflex and the relationship between PUI (pupillary unrest index measurement duration and sleepiness assessment validity, were assessed. Conclusions The results of the pilot studies were sufficient to develop minimum requirements for a PLR sensor that would be capable of estimating the level of fatigue with accuracy of a PUI method, but at a 5 times faster rate.

A document describes cryogenic test architecture for the James Webb Space Telescope (JWST) integrated science instrument module (ISIM). The ISIM element primarily consists of a mechanical metering structure, three science instruments, and a fine guidance sensor. One of the critical optomechanical alignments is the co-registration of the optical telescope element (OTE) exit pupil with the entrance pupils of the ISIM instruments. The test architecture has been developed to verify that the ISIM element will be properly aligned with the nominal OTE exit pupil when the two elements come together. The architecture measures three of the most critical pupil degrees-of-freedom during optical testing of the ISIM element. The pupil measurement scheme makes use of specularly reflective pupil alignment references located inside the JWST instruments, ground support equipment that contains a pupil imaging module, an OTE simulator, and pupil viewing channels in two of the JWST flight instruments. Pupil alignment references (PARs) are introduced into the instrument, and their reflections are checked using the instrument's mirrors. After the pupil imaging module (PIM) captures a reflected PAR image, the image will be analyzed to determine the relative alignment offset. The instrument pupil alignment preferences are specularly reflective mirrors with non-reflective fiducials, which makes the test architecture feasible. The instrument channels have fairly large fields of view, allowing PAR tip/tilt tolerances on the order of 0.5deg.

We have reported a case of classic Stevens-Johnson syndrome in association with treatment using a cobalt radiation therapy unit. Previous reports of such an association have been extremely rare. At the time of the reaction, the patient's only medications were methyldopa and trichlormethiazide. Other drugs in the thiazide class have been associated with such a reaction. We feel this is an unlikely association in our patient, however, because she had been on trichlormethiazide for a number of years. This report suggests the role of radiotherapy as a rare cause of Stevens-Johnson syndrome. 14 references

To analyze the status and the influence factors of exercise and sedentary activities in the leisure time among third and fourth grade pupils in Qingdao, Tai' an and Yantai city of Shandong province. With random cluster sampling, a total of 2283 primary students were selected from three cities of Shandong province. Questionnaires were used to collect the information on their exercise, sedentary activities. In the past week the participation rate of exercise in the leisure time among the pupils was 65.9%. Among the pupils who participated exercise, the average days of moderate and high-intensity exercise was four, and the average daily exercise time was 30 minutes. The average time of sedentary activities in the leisure time was 0.9 h/d, and the rate of 2 hours and over per day of sedentary activities was 13.6%. Pupils participating the exercise was related to their area, gender, their satisfaction of their body image and their parents' exercise. Their sedentary patterns was related to their understanding of their own body weight and their parents' sedentary behavior. Intervention related to physical activity should be strengthened among pupils and their parents to promote their physical activity level.

We describe a recent case of Stevens-Johnson Syndrome. A 49-year-old man was admitted to the Intensive Care Unit of an Anaesthesia and Resuscitation Department because of a Fournier gangrene that derived in a sepsis, ventilator-associated pneumonia, and renal failure. He was under treatment with cefepime and suffered a generalized status epilepticus, so started treatment with phenytoin. The next day he developed a "maculous cutaneous eruption in trunk and lower limbs" compatible with a Stevens-Johnson Syndrome. Stevens-Johnson Syndrome is a very severe and potentially fatal multiorganic disease, especially when present in critically ill patients, with a strong drug-related etiology, especially with antiepileptic drugs.
Aggressive behaviour in pupils is expressed in, e.g., bullying, sexual harassment, and violence. Different kinds of variables could be relevant in explaining a pupil's aggressive or victim behaviour. To develop a multilevel theoretical and empirical explanation for different kinds of aggressive and victim behaviour displayed by pupils in a classroom and school environment. A national survey was carried out to identify different kinds of aggressive and victim behaviour displayed by pupils and to assess other variables related to pupils, classes, and schools. A total of 1998 pupils from 100 third and fourth year classes attending 71 different secondary schools took part in the research. Data were analysed by a series of secondary multilevel analyses using the MLA-program. Being a boy, being more extravert, being more disagreeable, coming across fewer teachers with positive teaching behaviour, and attending a lower type of secondary school, help explain why someone is a perpetrator as such. Being a boy, being more disagreeable, being more emotionally unstable, being open to new ideas, and seeing more teachers as being strict, function as explanatory pupil variables for victim behaviour. Other pupil level variables determine more specific aggressive and victim behaviour aspects. Various other class level and school level variables are relevant, too. Personal and environmental pupil variables are more important than class variables but class variables are in turn more important than school variables in explaining a pupil's aggressive and victim behaviour.

Changes in pupil size at constant light levels reflect the activity of neuromodulatory brainstem centers that control global brain state. These endogenously driven pupil dynamics can be synchronized with cognitive acts. For example, the pupil dilates during the spontaneous switches of perception of a constant sensory input in bistable perceptual illusions. It is unknown whether this pupil dilation only indicates the occurrence of perceptual switches, or also their content. Here, we measured pupil diameter in human subjects reporting the subjective disappearance and re-appearance of a physically constant visual target surrounded by a moving pattern ('motion-induced blindness' illusion). We show that the pupil dilates during the perceptual switches in the illusion and a stimulus-evoked 'replay' of that illusion. Critically, the switch-related pupil dilation encodes perceptual content, with larger amplitude for disappearance than re-appearance. This difference in pupil response amplitude enables prediction of the type of report (disappearance vs. re-appearance) on individual switches (receiver-operating characteristic: 61%). The amplitude difference is independent of the relative durations of target-visible and target-invisible intervals and subjects' overt behavioral report of the perceptual switches. Further, we show that pupil dilation during the replay also scales with the level of surprise about the timing of switches, but there is no evidence for an interaction between the effects of surprise and perceptual content on the pupil response. Taken together, our results suggest that pupil-linked brain systems track both the content of, and surprise about, perceptual events. © 2015 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

Steven Weinberg visiting the ATLAS cavern accompanied by Peter JenniIt was no surprise that the CERN audience arrived early in the Globe of Science and Innovation for the colloquium on 7 July. Nobel laureate Steven Weinberg is one of the major contributors to the Standard Model of particle physics. He received the Nobel Prize for Physics in 1979 for his work on the unified theory of the electromagnetic and weak interactions, one of the essential pillars of the Standard Model. After lunch at CERN and a visit to ATLAS, Weinberg gave a colloquium on "The Quantum Theory of Fields: Effective or Fundamental" to a packed audience. In his talk, he looked at how the use of quantum field theory in particle physics has fluctuated in popularity since Paul Dirac first introduced the approach to describe the interaction of particles with electromagnetic fields in the late 1920s. In particular, he posed the question: Is quantum field theory fundamental or does it a...

Mycoplasma pneumoniae is a common cause of community-acquired respiratory illness in the adolescent population. Stevens-Johnson syndrome is an extrapulmonary manifestation that has been associated with M. pneumoniae infections. Three adolescent males presented within a 1-month period with M. pneumoniae respiratory illnesses and severe mucositis but without the classic rash typical of Stevens-Johnson. Diagnosis was facilitated by the use of a polymerase chain reaction-based assay. This case series highlights the potential for M. pneumoniae-associated Stevens-Johnson syndrome to occur without rash and supports the use of polymerase chain reaction for early diagnosis.
Full Text Available The aim of the study is to clear the significance of craft skills for the pupils in age nine and twelve years. More than 200 pupils were asked to define, what are the most important skills for the pupils of their age. The results bring out that category of the skills related to craft subject is of the most presented categories in pupils' self description. Thus the primary school pupils essentially defined themselves by the activities they could do practically (building, cooking, repairing of things. The most undefined relation to craft activities is reflected in the answer of smaller boys in our study. A suspicion arisen from the analysis of pupils' sayings, that the craft lessons in the 1st school stage tend to be organized kind of poorly was asserted by the teachers who pointed out the need for special rooms and materials to implement different techniques.

Waste-water disposal is a major concern of the petroleum business, especially because of complications associated with many produced-water surface-impoundment percolation facilities. In the San Joaquin Valley, California, the current environmental regulations protecting the potentially usable groundwaters are stringent. the Stevens has significant potential as a disposal zone that may offer considerable capacity when the project is designed using proper geologic and engineering studies. The Stevens sands are well known for their oil-producing capabilities, however, not much has been published regarding its suitability as a zone for deep well injection. Conditions that make the Stevens potentially suitable include (1) adequate confinement providing geologic separation from the groundwater sources in the basin, (2) storage capacity, and (3) large areal extent. Because the search for acceptable disposal options is becoming critical, the current class II disposal options is becoming critical, the current class II disposal activities in the Stevens sands were reviewed and the areas offering the greatest future potential were identified. The authors then discuss class II disposal projects in Stevens sands in the West Bellevue and Midway Sunset oil fields and estimate the ultimate basin-wide disposal capacity of the Stevens

School-based physical education (PE) is often proposed as a strategy for obesity prevention and treatment. Thus the role of PE teachers is crucial on this field. The purpose of this study was to investigate the perception of PE teachers towards overweight and obese pupils aged 13-15 years, especially psychosomatic problems and support for obese adolescents in realisation of physical activity programme. A random sample of 185 PE teachers from 112 lower secondary schools in Poland were surveyed regarding their perception of pupils obesity and their support for obese adolescents. PE teachers observed many negative features among obese pupils: Two thirds of teachers (67% male and 74% teachers with work experience 6-10 years) observed decreased physical fitness and exercise capacity in this group of pupils. Body-related barriers in obese pupils and anxiety caused by weight related peer teasing were observed by respectively 30% and 20% teachers more often women teachers and teachers with shorter work experience. PE teachers were engaged in activities to support obese pupils: 90% of them assessed obese pupils by personal development, 70% conducted counseling and 20% cooperated with obese pupils' parents. Two third of teachers reported successes in their work with obese pupils. Their difficulties were connected with body-related barriers in pupils (24%), and aversion to exercise and physical efforts and location of PE lessons at school (9-16%). 1. The PE teachers can play an important role in preventing and combating obesity in pupils. 2. PE teachers should be motivated to organize interesting PE lessons, school sport and competitions for both normal and overweight pupils.

Attentional effort relates to the allocation of limited-capacity attentional resources to meet current task demands and involves the activation of top-down attentional systems in the brain. Pupillometry is a sensitive measure of this intensity aspect of top-down attentional control. Studies relate pupillary changes in response to cognitive processing to activity in the locus coeruleus (LC), which is the main hub of the brain's noradrenergic system and it is thought to modulate the operations of the brain's attentional systems. In the present study, participants performed a visual divided attention task known as multiple object tracking (MOT) while their pupil sizes were recorded by use of an infrared eye tracker and then were tested again with the same paradigm while brain activity was recorded using fMRI. We hypothesized that the individual pupil dilations, as an index of individual differences in mental effort, as originally proposed by Kahneman (1973), would be a better predictor of LC activity than the number of tracked objects during MOT. The current results support our hypothesis, since we observed pupil-related activity in the LC. Moreover, the changes in the pupil correlated with activity in the superior colliculus and the right thalamus, as well as cortical activity in the dorsal attention network, which previous studies have shown to be strongly activated during visual tracking of multiple targets. Follow-up pupillometric analyses of the MOT task in the same individuals also revealed that individual differences to cognitive load can be remarkably stable over a lag of several years. To our knowledge this is the first study using pupil dilations as an index of attentional effort in the MOT task and also relating these to functional changes in the brain that directly implicate the LC-NE system in the allocation of processing resources.

To study the different pupil shapes adopted by the different animal species. Review of the related literature, using PubMed database. The initial search strategy was pupil shape (limited to animals). The first volume of System of Ophthalmology (Duke-Elder) and Evolution's witness (I. Schwab) were also reviewed. An optic illusion called pseudopupil is usually observed in the compound eyes of insects. The pupil is circular in most vertebrates, however slit vertical pupils are present in cats and in some snake species. Vertical pupils could have a photoprotective function, as it makes a more complete closure possible in photopic conditions, and helps to camouflage the predator. It has also been hypothesized that it could help to correct chromatic aberration. Ruminants are usually endowed with horizontal pupils. This shape could improve the capacity of the eye to detect vertical silhouettes. Some marine animals have crescent-shaped pupils. In these animals, a superior operculum helps to protect the inferior retina from the great amount of light coming from above. There is a surprising variability in pupil shape. Through this variability, nature has fitted the eye to different circumstances. The theories proposed to explain this high variability are discussed in detail in the article.

fMRI investigations in healthy humans have documented phasic changes in the level of activation of the right temporal-parietal junction (TPJ) during cued voluntary orienting of spatial attention. Cues that correctly predict the position of upcoming targets in the majority of trials, i.e., predictive cues, produce higher deactivation of the right TPJ as compared with non-predictive cues. Since the right TPJ is the recipient of noradrenergic (NE) innervation, it has been hypothesised that changes in the level of TPJ activity are matched with changes in the level of NE activity. Based on aforementioned fMRI findings, this might imply that orienting with predictive cues is matched with different levels of NE activity as compared with non-predictive cues. To test this hypothesis, we measured changes in pupil dilation, an indirect index of NE activity, during voluntary orienting of attention with highly predictive (80% validity) or non-predictive (50% validity) cues. In agreement with current interpretations of the tonic/phasic activity of the Locus Coeruleus-Norepinephrinic system (LC-NE), we found that the steady level of cue predictiveness that characterised both the predictive and non-predictive conditions caused, across consecutive blocks of trials, a progressive decrement in pupil dilation during the baseline-fixation period that anticipated the cue period. With predictive cues we observed increased pupil dilation as compared with non-predictive cues. In addition, the relative reduction in pupil size observed with non-predictive cues increased as a function of cue-duration. These results show that changes in the predictiveness of cues that guide voluntary orienting of spatial attention are matched with changes in pupil dilation and, putatively, with corresponding changes in LC-NE activity.

Attention-deficit/hyperactivity disorder (ADHD) diagnosis is based on reported symptoms, which carries the potential risk of over- or under-diagnosis. A biological marker that helps to objectively define the disorder, providing information about its pathophysiology, is needed. A promising marker of cognitive states in humans is pupil size, which reflects the activity of an 'arousal' network, related to the norepinephrine system. We monitored pupil size from ADHD and control subjects, during a visuo-spatial working memory task. A sub group of ADHD children performed the task twice, with and without methylphenidate, a norepinephrine-dopamine reuptake inhibitor. Off-medication patients showed a decreased pupil diameter during the task. This difference was no longer present when patients were on-medication. Pupil size correlated with the subjects' performance and reaction time variability, two vastly studied indicators of attention. Furthermore, this effect was modulated by medication. Through pupil size, we provide evidence of an involvement of the noradrenergic system during an attentional task. Our results suggest that pupil size could serve as a biomarker in ADHD.

We explored whether object behavioral priming and pupil changes occur in the absence of recognition memory. Experiment 1 found behavioral priming for unrecognized objects (Ms) regardless of whether they had been encoded perceptually or conceptually. Using the same perceptual encoding task, Experiment 2 showed greater pupil dilation for Ms than for correct rejections of unstudied objects (CRs) when reaction times were matched. In Experiment 3, there was relatively less pupil dilation for Ms than for similarly matched CRs when objects had been encoded conceptually. Mean/peak pupil dilation for CRs, but not Ms, increased in Experiment 3, in which novelty expectation was also reduced, and the pupillary time course for both Ms and CRs was distinct in the two experiments. These findings indicate that both behavioral and pupil memory occur for studied, but unrecognized stimuli, and suggest that encoding and novelty expectation modulate pupillary memory responses. © 2015 Society for Psychophysiological Research.

PURPOSE. The contraction and dilation of the iris muscle that controls the amount of light entering the retina causes pupil accommodation. In this study, experiments were performed and two of the three factors that influence pupil accommodation were analyzed: lighting conditions and depth fixations. The psychological benefits were not examined, because they could not be quantified. METHODS. A head-wearable eyeglasses-based, eye-capturing device was designed to measure pupil size. It included a near-infrared (NIR) camera and an NIR light-emitting diode. Twenty-four subjects watched two-dimensional (2D) and three-dimensional (3D) stereoscopic videos of the same content, and the changes in pupil size were measured by using the eye-capturing device and image-processing methods: RESULTS. The pupil size changed with the intensity of the videos and the disparities between the left and right images of a 3D stereoscopic video. There was correlation between the pupil size and average intensity. The pupil diameter could be estimated as being contracted from approximately 5.96 to 4.25 mm as the intensity varied from 0 to 255. Further, from the changes in the depth fixation for the pupil accommodation, it was confirmed that the depth fixation also affected accommodation of pupil size. CONCLUSIONS. It was confirmed that the lighting condition was an even more significant factor in pupil accommodation than was depth fixation (significance ratio: approximately 3.2:1) when watching 3D stereoscopic video. Pupil accommodation was more affected by depth fixation in the real world than was the binocular convergence in the 3D stereoscopic display.

Acute bronchial mucosal sloughing related to Toxic Epidermal Necrolysis (Lyell syndrome) is widely reported in literature. On the contrary severe respiratory involvement is rare in post-infectious or toxic Epitheliolysis (Stevens-Johnson syndrome). There is no well-known predictive sign of bronchial epithelium involvement. An 18-year-old patient was admitted for Stevens-Johnson syndrome related to sulfasalazine (salazosulfapyridine). There were no respiratory signs. An acute respiratory failure occurred 36 hours after from admission due to an obstructive and desquamative necrosis of the tracheobronchial epithelium. We purpose that a fiberoptic laryngoscopy should be performed even in non-dyspneic patients suffering from Stevens-Johnson syndrome if hypersecretion is present. Fiberoptic bronchoscopy can be helpful in these cases.

Tom Stevens' lab has explored the subunit composition and assembly of the yeast V-ATPase for more than 30 years. Early studies helped establish yeast as the predominant model system for study of V-ATPase proton pumps and led to the discovery of protein splicing of the V-ATPase catalytic subunit. The Vma - phenotype, characteristic of loss-of-V-ATPase activity in yeast was key in determining the enzyme's subunit composition via yeast genetics. V-ATPase subunit composition proved to be highly conserved among eukaryotes. Genetic screens for new vma mutants led to identification of a set of dedicated V-ATPase assembly factors and helped unravel the complex pathways for V-ATPase assembly. In later years, exploration of the evolutionary history of several V-ATPase subunits provided new information about the enzyme's structure and function. This review highlights V-ATPase work in the Stevens' lab between 1987 and 2017. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Full Text Available We analyzed the convictions of the teachers about scholastic failure and their perception of the activities they use in work with unsuccessful pupils. The theoretical basis for our research was the belief that there is a connection between the teacher's convictions and their everyday practices. The aim was to examine: 1 the teachers' convictions about the nature of academic failure, traits of the failing students, adequacy of after-class sessions and group work in overcoming the problem of academic failure, and 2 the teachers' perception of their own responsibility and engagement in supporting failing pupils. A set of parametric statistical techniques was used to analyze the responses of 1441 elementary-school teachers to the items related to academic failure in the questionnaire about current school problems. The results show that 1 the teachers have optimistic convictions about cognitive abilities of failing pupils and see after-class sessions as a good opportunity to work with them; they state that 2 they additionally prepare classes for work with failing pupils and stimulate them during regular classes and believe that failing pupils are successful in outdoor activities; 3 they have no definite opinion about the role of the teacher and adequacy of group work in overcoming the problem. The concluding observations stress the need for a detailed analysis of the activities based on the teacher's convictions about academic failure and support to failing pupils.

An interferometer objective lens (or diverger) may be used to transform a collimated beam into a diverging or converging beam. This innovation provides an objective lens that has diffraction-limited optical performance that is optimized at two sets of conjugates: imaging to the objective focus and imaging to the pupil. The lens thus provides for simultaneous delivery of a high-quality beam and excellent pupil resolution properties.

Etanercept and other anti-TNF-alpha agents have been indicated as a therapeutic option in severe drug reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis. Etanercept has been shown to quickly reduce the detachment of the epidermis and shorten healing time. Cases of etanercept-induced severe adverse drug reactions were also described. A 27-year-old woman with a 4-year history of etanercept and sulfasalazine treatment for rheumatoid arthritis was admitted with Stevens-Johnson syndrome. The patient received one dose of an OTC drug containing acetaminophen, phenylephrine and pheniramine two days prior to developing fist mucocutaneous symptoms. The most probable causative agent was paracetamol. Throughout the successful routine therapy of Stevens-Johnson syndrome etanercept therapy was continued. Sulfosalazin administration was stopped and administered again after recovery with no recurrence of the skin and mucosal symptoms. This case indicates that there is no justification for discontinuation of long-term anti-TNF-alpha treatment in patients who develop Stevens- Johnson syndrome / toxic epidermal necrolysis.

Secondary school can be a stressful period for adolescents, having to cope with many life changes. Very little research has been conducted on the mental health status of secondary school pupils in South East Asian countries, such as Vietnam.The study aimed to explore perceptions of mental health status, risk factors for mental health problems and strategies to improve mental health among Vietnamese secondary school students. A qualitative design was used to address the main study question including: six in-depth interviews conducted with professionals (with two researchers, two psychiatrists, and two secondary school teachers) to learn about their experience of mental health problems among secondary school pupils; 13 focus group discussions (four with teachers, four with parents, and five with pupils); and 10 individual in-depth interviews with pupils who did not take part in the FGDs, to reflect on the collected data and to deepen the authors' understanding. All interviews and FGDs were audio-taped, transcribed and analyzed for the identification of emerging issues using qualitative techniques of progressive coding, analytic memoing and ongoing comparison. Our study confirms the need to pay attention to mental health of pupils in Vietnam. Depression, anxiety, stress, suicidal thoughts and suicide attempts were seen as major problems by all stakeholders. Mental health problems were mainly associated with academic pressure, resulting from an overloaded curriculum and pressure from teachers and parents to succeed. The study found that pupils' mental health demands interventions at many levels, including at the level of government (Ministry of Education and Training), schools, communities, families and pupils themselves. Vietnamese secondary school pupils feel that their mental health status is poor, because of many risk factors in their learning and living environment. The need now is to investigate further to identify and apply strategies to improve students' mental

Full Text Available Background: The key factor that affects the success of shaping positive attitudes towards regular life-long performance of physical activity (PA is the pupils' level of inner motivation. This is influenced, among other things, by their family background, the educational institution that they attend and the educator's competencies. Objective: The purpose of this study was to describe and analyse the attitudes among pupils with sensory disabilities in physical education (PE classes. A partial objective was to compare the preferences for various PA by pupils with sensory disabilities in PE classes. Method: A non-standardized questionnaire was used to collect the data. The sample was based on the following features: a a participant had to be deaf or hard of hearing, b a participant had to have a visual disability, and c had to have been educated in special educational settings. The data were quantified on the percentage basis. To carry out cross-group statistical testing of differences, a ratio analysis with the help of the Chi-square test was applied. The level of statistical significance was set to p < .05. We analysed the data of 70 pupils attending the second stage of two elementary schools in Slovakia: a 37 pupils (22 boys and 15 girls, age 13.3 ± 1.45 years from a school for the deaf, and b 33 pupils (14 boys and 19 girls, age 13.4 ± 1.41 years from a school for the blind. Results: The differences in the preferences for various PA during PE classes in the cross-group comparison of pupils with sensory disabilities were discovered. A comparison of the opinions of pupils with sensory disabilities pointed out a difference consisting in a higher percentage of positive attitudes among pupils with visual disabilities in indicators of popularity, importance, the pupils' efforts and feelings towards education. A statistically significant difference was discovered only in feelings during PE classes. This result may be considered

Full Text Available Normative rules of standard Serbian language are acquired during primary and secondary education through curriculum demands of Serbian language instruction, which takes place in three fields: grammar, orthography and culture of expression. Topic of interest in this paper is the quality of written expression of 6th and 7th grade pupils, in the context of all three fields specified to be mastered by the curriculum of Serbian language. Research comprised 148 primary school pupils from Belgrade. Linguistic analysis of spontaneously created written text was performed, in the conditions where it was not explicitly demanded form the pupil to write correctly. The results indicate that the majority of pupils make spelling and grammatical errors, meeting the condition for the basic level of mastering the knowledge in Serbian language according to the standards specified for the end of compulsory education. In addition to this, a considerable majority of pupils has a satisfactory level of culture of written expression. Pupils more often make spelling than grammatical errors. Seventh grade pupils are better than sixth grade pupils with respect to adhering to grammar rules and according to culture of written expression, while the mark in Serbian language and general school achievement of pupils correlate only with the degree of adhering to the orthographic rules. It was concluded that not only individual programs of support for pupils who make more errors are necessary, but also launching national projects for the development of linguistic competence of the young in Serbia.

Full Text Available Wallace Stevens’s “The Man with the Blue Guitar” (1937 is widely recognized as one of the most important and influential poems of the 20th century. Inspired by Picasso’s painting The Old Guitarist, the poem in turn inspired Michael Tippett’s sonata for solo guitar, “The Blue Guitar” (Tippett 1983 and David Hockney’s The Blue Guitar: Etchings by David Hockney who was inspired by Wallace Stevens who was inspired by Pablo Picasso (Hockney and Stevens 1977. Central to “The Man with the Blue Guitar,” the metaphor of the musical instrument as a transformational symbol of the imagination is common in Stevens’s poems. The structure of “The Man with the Blue Guitar,” according to J. Hillis Miller, is the structure of stream-of-consciousness. Stevens’s poem creates what has been called “the deconstructed moment in modern poetry,” “an attempt to project a spatialized time that can be viewed from the privileged position of a timeless, static moment capable of encompassing a life at a glance” (Jackson 1982. This consciousness, which Derrida refers to as the “trace,” Stevens calls “the evasive movement of language.” The trace is the perception of the absence of meaning after the word or perception has passed, the glimpse of a hidden meaning that immediately vanishes. Stevens’s poem influenced not only other poets, artists and composers; references to and echoes of his ideas and techniques can be seen in popular music and culture well into the 21st century.

Full Text Available Current research in the field of education indicates that the behaviour of the teacher affects significantly the quality and level of the pupil's motivation. The aim of our research was to determine the structure of the motivational style of teachers seen from the pupils' perspective, and to find out whether the pupils' perceptions of the teacher's motivational style depend upon cultural-educational influences of the family, and some characteristics of the students (academic achievements, gender. The sample included 856 pupils from 40 elementary schools in Serbia. We used the questionnaire with Likert's scale to obtain the evaluation of the teachers' behaviours. By the factor analysis we extracted three components of the teacher' behaviour: stimulating pupils' interest and competences, de-motivational teachers' behaviours and stimulating freedom of thinking and expression. The results show that the pupils whose parents have lower levels of education think that the behaviour of the teachers is directed to stimulating interest and competencies, as well as freedom of thinking and speech than the pupils of the parents of higher educational status. The control of the influence of the education of parents showed that the pupils of lower academic achievement perceive the teacher's behaviour as de-motivational. Compared to girls boys estimate more highly that teachers stimulate their interests and competencies. A suggestion is offered how a teacher should develop a behavioural style which would positively influence the quality of the pupils' motivation.

Full Text Available The school is an educational institution that has to provide appropriate control of adults over pupils, which they do. Nevertheless, violence cannot be avoided. Pupils encounter peer violence in different roles, as observers, victims, perpetrators, or both. The objective of our research was to examine how often pupils are victims of peer violence, and to what extent the latter depends on pupils’ gender and age. The results of the research made among pupils in the fifth, seventh, and eighth grades of various primary schools across Slovenia showed that 24.1 per cent of pupils had already been victims of peer violence. The ones that they tend to tell about such episodes are their parents. The results have also shown that school is really a place where violence is very common, and that psychological and verbal abuse are the most common types of violence used.

An objective lens includes multiple optical elements disposed between a first end and a second end, each optical element oriented along an optical axis. Each optical surface of the multiple optical elements provides an angle of incidence to a marginal ray that is above a minimum threshold angle. This threshold angle minimizes pupil ghosts that may enter an interferometer. The objective lens also optimizes wavefront delivery and pupil imaging onto an optical surface under test.

Full Text Available OBJECTIVE: To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome. METHODS: A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included the patient's sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of the inferior conjunctival fornix were performed in both eyes. Fourteen days before scraping, the patients were asked to interrupt all topical medication and start using 0.5% nonpreserved methylcellulose. The microbiological evaluation included microorganism identification and determination of antibiotic sensitivity. RESULTS: Of 22 patients (41 eyes, 14 (64% were females, and eight (36% were males. The mean age was 33.2 years, and the mean duration of disease was 15.6 years. Visual acuity ranged from light perception to 20/25 (1.57 logMar. The treatment received by most patients consisted of tear substitutes, topical antibiotics, and contact lenses. Bacterial identification was positive in 39 eyes (95% and negative in two eyes (5%. Gram-positive cocci accounted for 55.5% of the microorganisms, whereas gram-positive bacilli and gram-negative bacilli accounted for 19% and 25.5%, respectively. Half of the patients (54% had multiple bacterial species in their flora, and only one bacterial species was identified in the other half. Resistant bacteria were isolated from four eyes. The antibiotic sensitivity results for the Streptococcus group showed the lowest sensitivity and the highest microbial resistance identified. CONCLUSION: Patients with Stevens-Johnson syndrome have a diverse conjunctival flora that includes many pathogenic species.

This research examined a novel suggestion regarding the involvement of the locus coeruleus-norepinephrine (LC-NE) system in orienting reflexive (exogenous) attention. A common procedure for studying exogenous orienting of attention is Posner's cuing task. Importantly, one can manipulate the required level of target processing by changing task requirements, which, in turn, can elicit a different time course of inhibition of return (IOR). An easy task (responding to target location) produces earlier onset IOR, whereas a demanding task (responding to target identity) produces later onset IOR. Aston-Jones and Cohen (Annual Review of Neuroscience, 28, 403-450, 2005) presented a theory suggesting two different modes of LC activity: tonic and phasic. Accordingly, we suggest that in the more demanding task, the LC-NE system is activated in phasic mode, and in the easier task, it is activated in tonic mode. This, in turn, influences the appearance of IOR. We examined this suggestion by measuring participants' pupil size, which has been demonstrated to correlate with the LC-NE system, while they performed cuing tasks. We found a response-locked phasic dilation of the pupil in the discrimination task, as compared with the localization task, which may reflect different firing modes of the LC-NE system during the two tasks. We also demonstrated a correlation between pupil size at the time of cue presentation and magnitude of IOR.

Full Text Available Group-living typically provides benefits to individual group members but also confers costs. To avoid incredulity and betrayal and allow trust and cooperation, individuals must understand the intentions and emotions of their group members. Humans attend to other's eyes and from gaze and pupil-size cues, infer information about the state of mind of the observed. In humans, pupil-size tends to mimic that of the observed. Here we tested whether pupil-mimicry exists in our closest relative, the chimpanzee (P. troglodytes. We conjectured that if pupil-mimicry has adaptive value, e.g. to promote swift communication of inner states and facilitate shared understanding and coordination, pupil-mimicry should emerge within but not across species. Pupillometry data was collected from human and chimpanzee subjects while they observed images of the eyes of both species with dilating/constricting pupils. Both species showed enhanced pupil-mimicry with members of their own species, with effects being strongest in humans and chimpanzee mothers. Pupil-mimicry may be deeply-rooted, but probably gained importance from the point in human evolution where the morphology of our eyes became more prominent. Humans' white sclera surrounding the iris, and the fine muscles around their eyes facilitate non-verbal communication via eye signals.

With the 2011 educational reform in France, a new course has been created in secondary schools : Methods & Practices in Science (MPS). The main goal was to improve the pupils working methods in science, including laboratory and field works. In addition, the pedagogy develops pupils autonomy and creativity, a key factor in a research process. Three teachers are working together (Mathematics, Physics and Geology-Biology), showing how different disciplines complement one another. Eventually, this is aimed at attracting more students in scientific sections. This course is optional, in the "seconde" class in French secondary schools (i.e., for 15 years old students). For the next class, they will have to choose between scientific, economic and literature sections : it is a useful option for them to decide which section has their preference. In my high-school in Clermont-Ferrand, we have chosen a research subject on hydrogeology & water quality improvement in region "Auvergne". The pupils will have to develop and set up appropriate tools to check and improve the water quality, related to different disciplines : - Geology & Biology: hydrogeology, effects of different pollutants on aquatic life, solutions to improve water quality (example of the natural water treatment zone in the lake of "Aydat, Auvergne, France"). - Physics & Chemistry: water potability criteria, pollution tests in water, water treatment plants working. - Mathematics: algorithm development, modeling on excel of the dispersion of pollutants The pedagogy of this course is new in French high-schools : pupils work in groups of three, so as to develop cooperation and autonomy. The teachers give the guidelines at the beginning of each working session, and answer the students questions when necessary. The evaluation is competence-based : instead of a mark, which is the main evaluation method in France, the pupils have to evaluate their own skills. Then, the teachers make an evaluation, and the global process is
Full Text Available Minocycline is an antibiotic of tetracycline derivatives that is commonly used in the treatment of moderate to severe acne vulgaris. It has been reported to cause rare adverse events from mild cutaneous eruption to severe forms including drug-induced lupus, serum sickness-like reaction, and hypersensitivity reactions, etc. The risks of adverse events attributed to minocycline have not been ascertained reliably and there are concerns about the safety of minocycline which could possibly result in life-threatening events such as the Stevens-Johnson syndrome. Here we demonstrate an unusual case of Stevens-Johnson syndrome in conjunction with bilateral parotitis after the intake of minocycline in a Korean boy suggesting discreet use of the drug.
Full Text Available This paper investigates the importance for pupils’ learning of being generally visibly active participant in a classroom discussion. A class of six year-old pupils was taught about the human skeletal system and other organs. To determine what they had learnt, they were asked to produce drawings before and after the course of teaching. The pupils’ participation in the class discussion during the course of teaching was given values on a scale from 1–8, the most talkative receiving the value 1 and the least talkative (or most quiet the value 8. The study showed that the less talkative the pupils were in the discussion the more they gained from the teaching. The results could not be accounted for by ceiling effects and similar patterns obtained across the materials used support the robustness of the findings. The study suggests that it cannot be assumed that participating in classroom discussion during the learning process is a necessary precondition for learning.

Full Text Available The presented text shows the results of research carried out within the dissertation thesis. The main topic is the phenomenon of sociocultural handicap of foreign pupils (pupils with a different mother tongue. The research is based on the expert belief that integration of foreign pupils (pupils with a different mother tongue into Czech schools and the training of teachers in this field is still somewhat marginal, even though there is a growing debate about increasing cultural diversity, increasing heterogeneity of schools and introduction of inclusive measures. The aim of the research was to analyze professional training of teachers in relation to the sociocultural handicap of foreign pupils (pupils with a different mother tongue. The goal was refined by the formulation of research questions: What possible problems (difficulties reflect teachers in the teaching process of foreign pupils? What procedures and strategies do teachers use to help these pupils to be integrated successfully? How do teachers assess their professional readiness for education of foreign pupils (whether they were sufficiently prepared to work with foreign pupils in the course of their undergraduate studies, where they find benefits, deficiencies in this training? How do students assess their undergraduate education for foreign-pupil teaching (whether they were ready to work with foreign pupils in their previous undergraduate education, where they find benefits, deficiencies in this training? The research used questionnaire survey techniques for teachers and students and semi-structured interviews for teachers. The partial technique was the analysis of study subjects focused on the education of foreign pupils at the Faculty of Education at West Bohemian University in Pilsen (hereinafter WBU. The research group was made up of teachers of the 1st grade of primary schools of the Pilsen and Karlovy Vary regions and students of the 4th grade of the field of Teaching for the

We present the case of a 21-year-old woman in whom Stevens-Johnson syndrome (SJS) developed after initiation of armodafinil. Although this rare and life-threatening reaction is listed on armodafinil's label, no cases have been reported in the literature. This case, in addition to an update of the drug's label after post-marketing research, both support the link between armodafinil and SJS. Providers should maintain a high clinical suspicion for SJS when starting therapy to minimize associated morbidity and mortality by discontinuing armodafinil at the onset of first symptoms. © 2018 American Academy of Sleep Medicine.

Full Text Available This paper describes how gender and age affect Japanese pupils’ motivation for learning English and their attitudes to communication with people from different cultures. A new foreign language curriculum was introduced to Japanese elementary schools in 2011. Although each school can officially choose any foreign language in its own right, most elementary schools are now conducting English activity. However, as most homeroom teachers lack both experiences and qualifications for teaching English, this activity puts them under pressure. In addition, the number of foreign assistant language teachers (ALTs is not sufficient in most elementary schools. The writer surveyed fifth and sixth grade pupils’ motivation and their communicative attitudes in Japan during 2010, before the new course program, “foreign language activities,” began in 2011. The data were collected from three elementary schools in Japan via a questionnaire. The items on the questionnaire are related to motivational attitudes, orientations (reasons for studying a foreign language, communicative attitudes and some other variables relevant to learning foreign languages. The main focus of this study is to examine motivational and attitudinal variables among the pupils with regard to learning English, especially gender and age effects on these variables. The results show that girls generally have higher scores on motivation and communicative attitudes. Most previous studies have also shown that girls generally have a positive attitude toward learning a foreign language. This study argues that the reason behind this positive attitude toward learning English is due to their positive attitude toward communication in general. With regard to the age, there are a few differences between two school grades. As there is only one year difference in age between fifth and sixth grade pupils, the result is to be expected. The study suggests that Japanese elementary schools face a number of

Controversy revolves around the question of whether psychological factors like attention and emotion can influence the initial feedforward response in primary visual cortex (V1). Although traditionally, the electrophysiological correlate of this response in humans (the C1 component) has been found to be unaltered by psychological influences, a number of recent studies have described attentional and emotional modulations. Yet, research into psychological effects on the feedforward V1 response has neglected possible direct contributions of concomitant pupil-size modulations, which are known to also occur under various conditions of attentional load and emotional state. Here we tested the hypothesis that such pupil-size differences themselves directly affect the feedforward V1 response. We report data from two complementary experiments, in which we used procedures that modulate pupil size without differences in attentional load or emotion while simultaneously recording pupil-size and EEG data. Our results confirm that pupil size indeed directly influences the feedforward V1 response, showing an inverse relationship between pupil size and early V1 activity. While it is unclear in how far this effect represents a functionally-relevant adaptation, it identifies pupil-size differences as an important modulating factor of the feedforward response of V1 and could hence represent a confounding variable in research investigating the neural influence of psychological factors on early visual processing.

Measurement of pupil size (pupillometry) has recently gained renewed interest from psychologists, but there is little agreement on how pupil-size data is best analyzed. Here we focus on one aspect of pupillometric analyses: baseline correction, i.e., analyzing changes in pupil size relative to a baseline period. Baseline correction is useful in experiments that investigate the effect of some experimental manipulation on pupil size. In such experiments, baseline correction improves statistical power by taking into account random fluctuations in pupil size over time. However, we show that baseline correction can also distort data if unrealistically small pupil sizes are recorded during the baseline period, which can easily occur due to eye blinks, data loss, or other distortions. Divisive baseline correction (corrected pupil size = pupil size/baseline) is affected more strongly by such distortions than subtractive baseline correction (corrected pupil size = pupil size - baseline). We discuss the role of baseline correction as a part of preprocessing of pupillometric data, and make five recommendations: (1) before baseline correction, perform data preprocessing to mark missing and invalid data, but assume that some distortions will remain in the data; (2) use subtractive baseline correction; (3) visually compare your corrected and uncorrected data; (4) be wary of pupil-size effects that emerge faster than the latency of the pupillary response allows (within ±220 ms after the manipulation that induces the effect); and (5) remove trials on which baseline pupil size is unrealistically small (indicative of blinks and other distortions).

Full Text Available Multiplicity of oscillatory phenomena in a range of infra-slow frequencies (<0.01 Hz has been described in mammalian brains at different levels of organisation. The significance and manifestation in physiology and/or behaviour of many brain infra-slow oscillations (ISO remain unknown. Examples of this phenomenon are two types of ISO observed in the brains of urethane-anaesthetised rats: infra-slow, rhythmic changes in the rate of action potential firing in a few nuclei of the subcortical visual system and a sleep-like cycle of activation/deactivation visible in the EEG signal. Because both of these rhythmic phenomena involve brain networks that can influence autonomic nervous system activity, we hypothesised that these two brain ISOs can be reflected by rhythmic changes of pupil size. Thus, in the present study, we used simultaneous pupillography and ECoG recording to verify the hypothesised existence of infra-slow oscillations in the pupil size of urethane-anaesthetised rats. The obtained results showed rhythmic changes in the size of the pupils and rhythmic eyeball movements in urethane-anaesthetised rats. The observed rhythms were characterised by two different dominant components in a range of infra-slow frequencies. First, the long component had a period of ≈ 29 minutes and was present in both the irises and the eyeball movements. Second, the short component had a period of ≈ 2 minutes and was observed only in the rhythmic constrictions and dilations of the pupils. Both ISOs were simultaneously present in both eyes, and they were synchronised between the left and right eye. The long ISO component was synchronised with the cyclic alternations of the brain state, as revealed by rhythmic changes in the pattern of the ECoG signal. Based on the obtained results, we propose a model of interference of ISO present in different brain systems involved in the control of pupil size.
Full Text Available The paper deals with the effects of specially programmed types of physical activities on the development of coordination of the pupils with developmental difficulties in regular elementary schools. The method of pedagogical research with parallel groups was used in the research which included 135 junior elementary-school pupils. Among them 90 pupils had one of developmental difficulties (intellectual disability, visual and hearing disturbances and they were divided into an experimental and a control group 1, while other pupils had typical development and they formed the control group 2 (n=45. Besides regular classes of physical education the experimental group was engaged in a special programme, devised and implemented into the Individual Educational Plan, as one of the types of intervention within the system of inclusive education. The research lasted for three months during which the groups were tested by the tests of coordination and the data obtained at the beginning and the end of the research period were processed by the application of univariant analysis of covariance and the T-test of the paired samples. The results show that the pupils with developmental difficulties can considerably progress in the development of coordination if their individual characteristics are recognized and optimal conditions are provided.

Full Text Available The research analyses characteristics of pragmatic abilities of storytelling of pupils with mild intellectual disabilities (MID, in the light of vocabulary characteristics, grammar structure and substantive structure of a story, considering their age and gender. The sample consists of 60 pupils with MID, aged 7 to 9, who attend special school. Child’s pragmatic abilities are assessed with The Storytelling Test. The research results reveal considerable progress of the older group in vocabulary, whereas the progress in grammatical and substantive structure was less substantial. When comparing achievements of pupils with MID according to the vocabulary, grammatical and substantive story structure, no gender differences are determined. A comparison of pragmatic abilities of younger and older groups of pupils with MID with the norms for peers with typical development shows minor deviation of the younger group. The research results reveal characteristics of pragmatic abilities of pupils with MID and can provide insights to speech therapists, teachers, special education teachers and counsellors when considering profiles of individuals that are taken as a basis for designing intervention programs. By implementing such program, we would encourage development of pragmatic abilities of pupils, thus affecting their academic achievements, communication competency and social skills.
Full Text Available The article presents tendencies of Holocaust denial among secondary school pupils in Slovenia. It focuses on research implemented in January 2012, in which 400 Slovenian secondary school pupils were included. In spite of the assumption that Holocaust denial amongst the youth in Slovenia already exists, we also assumed that a degree of Holocaust denial amongs Slovenian pupils is lower that amongst their peers in other EU countries. Research also inquired about the level of anti-Semitism in conjunction with Holocaust denial. The research project confirmed that students on lower levels of high school education and with less history and sociology lessons in curriculum are more receptive for the Holocaust denial and anti-Semitism is more present in this demographic. The level of Holocaust denial amongst secondary school pupils is not negligible; it suggests that this topic should be more thoroughly discussed in secondary schools.

To compare the efficacy of the olive tipped (OT) cannula to the conventional Steven's cannula for sub-Tenon block (STB) before cataract surgery. This prospective, randomized, double-masked compared STB delivered in cataract surgery patients with an OT cannula or a conventional Steven's cannula (ST). Outcome variables included the akinesia score and lid movement scores at 5 and 10 min. The patient perception of pain during delivery of the STB and surgery were also compared between groups. Surgeon satisfaction with anesthesia was compared between groups. P <0.05 was statistically significant. There were sixty patients in each group. The age between groups was not statistically different ( P = 0.4). The body mass index was higher in the ST group compared to the OT group ( P < 0.001). The akinesia score at 5 and 10 min did not differ between groups ( P = 0.07 and P = 0.6, respectively). The patient perception of pain during STB and surgery were similar between groups ( P = 0.1 and P = 0.06, respectively). There were six patients with mild chemosis and redness in the OT group and 15 patients in the ST group. An OT cannula is equally effective as the conventional Steven's cannula for delivering STB anesthesia before cataract surgery.

Across species, oxytocin, an evolutionarily ancient neuropeptide, facilitates social communication by attuning individuals to conspecifics' social signals, fostering trust and bonding. The eyes have an important signalling function; and humans use their salient and communicative eyes to intentionally and unintentionally send social signals to others, by contracting the muscles around their eyes and pupils. In our earlier research, we observed that interaction partners with dilating pupils are trusted more than partners with constricting pupils. But over and beyond this effect, we found that the pupil sizes of partners synchronize and that when pupils synchronously dilate, trust is further boosted. Critically, this linkage between mimicry and trust was bound to interactions between ingroup members. The current study investigates whether these findings are modulated by oxytocin and sex of participant and partner. Using incentivized trust games with partners from ingroup and outgroup whose pupils dilated, remained static or constricted, this study replicates our earlier findings. It further reveals that (i) male participants withhold trust from partners with constricting pupils and extend trust to partners with dilating pupils, especially when given oxytocin rather than placebo; (ii) female participants trust partners with dilating pupils most, but this effect is blunted under oxytocin; (iii) under oxytocin rather than placebo, pupil dilation mimicry is weaker and pupil constriction mimicry stronger; and (iv) the link between pupil constriction mimicry and distrust observed under placebo disappears under oxytocin. We suggest that pupil-contingent trust is parochial and evolved in social species in and because of group life. © 2017 The Authors.

Pupil responses are known to indicate brain processes involved in perception, attention and decision-making. They can provide an accessible biomarker of human memory performance and cognitive states in general. Here we investigated changes in the pupil size during encoding and recall of word lists. Consistent patterns in the pupil response were found across and within distinct phases of the free recall task. The pupil was most constricted in the initial fixation phase and was gradually more dilated through the subsequent encoding, distractor and recall phases of the task, as the word items were maintained in memory. Within the final recall phase, retrieving memory for individual words was associated with pupil dilation in absence of visual stimulation. Words that were successfully recalled showed significant differences in pupil response during their encoding compared to those that were forgotten - the pupil was more constricted before and more dilated after the onset of word presentation. Our results suggest pupil size as a potential biomarker for probing and modulation of memory processing.
Full Text Available The main purpose of our study was to investigate how basic school pupils and teachers perceive and understand bullying. The participants in the study were 58 teachers and 396 pupils in basic school. The results indicate that both teachers and pupils perceive verbal bullying as the most frequent form of bullying compared to physical and relational bullying. Pupils report perceiving more bullying than teachers. Both pupils and teachers perceive physical and verbal bullying as more serious forms of bullying compared to relational bullying and report feeling more empathy toward victims of these two forms of bullying. In addition, teachers report that they are more willing to intervene in cases of physical and verbal bullying. There are significant differences between pupils’ and teachers’ reports of the likelihood of teachers’ interventions in cases of bullying; compared to pupils teachers report a higher likelihood of their intervention..

Tadpole pupil is a rarely encountered phenomenon caused by episodic, segmental iris dilator muscle spasm of short duration (2-15 minutes), occurring in clusters without a known precipitating factor. It has most commonly been described in women aged 28 to 48 years. A few hypotheses on pathogenesis have been discussed but none has been proved. Here, we present an adolescent girl with bilateral tadpole pupil that appeared during physical exercise. This is the first pediatric case of tadpole pupil, not caused by preceding surgery, to be published. Based on (1) this case in which tadpole pupil developed when the norepinephrine level rose during exercise, (2) the high ratio of patients with tadpole pupil who concurrently have or later develop Horner syndrome, in which denervation hypersensitivity is well described, (3) a previous report of a patient with both tadpole pupil and Horner syndrome who had denervation hypersensitivity on pharmacological testing, (4) a 29-year-old man with unilateral tadpole pupil induced by exercise, and (5) a 19-year-old man with bilateral tadpole pupil and possible autonomic neuropathy, we suggest denervation hypersensitivity as a probable pathogenic mechanism causing tadpole pupil. In addition, a suggestion for investigations to be performed in future pediatric cases is provided. Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Since the introduction of Special education in Kenya in 1946 numerous special schools have been established. However there has been a move toward integration and later inclusion of students with disabilities in regular schools. Inclusion has its own challenges. Kenya as a rapidly developing country is undergoing drastic social economic and cultural changes. Consequently learners with disabilities in inclusive schools experience a number of challenges. These challenges bring into focus the need of reinforcing various modifications especially in classroom environments in learning institutions to counteract challenges brought about by the change from integration to inclusive education. With this realization the study sought to examine the classroom curricular preparedness of inclusive schools for the pupils with physical disability. Adaptations that ought to be made under classroom curricular category should ideally aid in lessening these challenges and impact positively on the pupils with physical disability and enhance their learning activities. The study utilized mixed method research approach where both Phenomenology and Descriptive survey research designs were made use of. The findings indicate that there are adequate classroom curricular adaptations for inclusion of pupils with physical disability

Ocular coloboma is sometimes accompanied by corectopia in humans and therefore ectopic pupil may indicate ocular coloboma in experimental animals. The RCS strain of rats has a low incidence of microphthalmia. We found that inferior ectopic pupil is associated exclusively with small-sized eyes in this strain. The objective of the current study was to evaluate whether inferior ectopic pupil is associated with iridal coloboma and other types of ocular coloboma in RCS rats. Both eyes of RCS rats were examined clinically, and those with inferior ectopic pupils underwent morphologic and morphometric examinations. In a prenatal study, coronal serial sections of eyeballs from fetuses at gestational day 16.5 were examined by using light microscopy. Ectopic pupils in RCS rats were found exclusively in an inferior position, where the iris was shortened. Fundic examination revealed severe chorioretinal coloboma in all cases of inferior ectopic pupil. The morphologic characteristics closely resembled those of chorioretinal coloboma in humans. Histopathologic examination of primordia showed incomplete closure of the optic fissure in 4 eyeballs of RCS fetuses. Neither F(1) rats nor N(2) (progeny of RCS × BN matings) displayed any ocular anomalies, including ectopic pupils. The RCS strain is a suitable model for human ocular coloboma, and inferior ectopic pupil appears to be a strong indicator of ocular coloboma.

Full Text Available The results of Slovene and foreign studies reveal the connection between literacy levels and the level of education, employment opportunities and consequent socio-economic status of individuals and families. Reading efficiency relating to reading comprehension is an important element of reading literacy performance. The findings of several authors indicate empirical evidence of the existence of deficits and poor reading comprehension in pupils living in poverty and stress the importance of offsetting deficits and developing reading comprehension. Results of both foreign and Slovene studies indicate that the program of reading comprehension should be implemented in this group of pupils. In the article, we want to present effectiveness of the reading comprehension improvement program in pupils living in poverty. According to the findings of our research, in which we structured and implemented the reading comprehension program for pupils living in poverty with the Metacognitive-intersentential model of reading comprehension, the reading comprehension of the experimental group pupils who participated in the program improved compared to the control group pupils who did not participate in the program. Experimental group pupils also significantly improved correctness of their reading, their vocabulary and skills of verbal expression. When the program ended, we tested its efficiency by applied tests. The results on the manifest variables indicated that the program was good and efficient for pupils who live in poverty and experience reading comprehension problems.
Full Text Available This paper reports findings from a study among 610 Year 7 (typically age 12 pupils at 27 nonselective secondary schools in three English regions: Cornwall and Devon, London, and Greater Manchester. Data was gathered in workshops, each with 15–25 pupils, who completed questionnaires and performed individual tasks, all related to their vocational and educational aims, their ideas on what counted as success, and the main influences on their forward thinking, then discussed their answers and results. The discussions were tape recorded. Most pupils expressed robust occupational aims, and most said that they wanted to go to university. Family class did not predict levels of educational or occupational aims, but was related to the importance attached to “the job that I want to do” in the pupils' forward thinking. SAT scores did predict levels of occupational aspiration, ideas on what counted as success, and by whom and what the pupils were most influenced. These findings are interpreted to challenge the view, on which a raft of current policies are based, that social class disparities in educational and labour market outcomes are due to the intergenerational transmission of low aspirations in lower-class families and neighbourhoods. The paper concludes with an alternative model of status transmission processes in which attainments during secondary education are posited as the key intervening variable.
Significantly, pupil-teacher ratios are very essential to quality of education. They perhaps rank alongside professional knowledge, skill, as well as strategies, in genuinely determining educational success and performance. This paper discusses pupil-teacher ratio and relevance that pupils seem to have a greater impact on ...

Full Text Available One of the most important preconditions for effective influence of physical body exercises among pupils during regular classes of physical education in schools is increased volume and quality of work and study. In order to increase volume and quality of work and study, it is necessary to carry out reform of education at elementary and lower level secondary education in Kosova in order to advance professional personnel and increase number of hours for sport and health education classes. Methods: This research is of a transversal nature, meaning that there has been a measurement of morphological and motoric indicators in the sample of 26 pupils of the age group of 15 years of the elementary and lower level school “Faik Konica” from Prishtina as an urbane center and sample of 30 pupils of elementary and lower level school „Avdulla Tahiri“ from Malisheva. 6 anthropometric and 4 motoric variables have been used (Kurelić et al., 1975. Anthropometric variables included: body height (ATV, length of foot (ADS, body mass (ATT, volume of upper arm in down position (AONL, volume of upper leg (AONK, volume of lower leg (AOPK. Motoric variables included: standing position distance jump (MFESDM, 30 meters distance running (MTR30V, bench bending (MFLPRK, and push-ups (MSKLEK. T-test analysis has been used for independent variables. Results: Obtained results from the statistical analysis demonstrate that anthropometric characteristics and motoric skills of two independent groups of pupils have normal distribution and no visible asymmetry and have tendency toward higher values (epikurtic. T-test analysis demonstrates that pupils from rural areas have lower muscular mass and lower motoric results. Discussion: Conditions for execution of physical education classes and lack of physical activities in the rural environment have strong influence on developments of morphological and motoric characteristics of pupils. Significant statistical differences obtained
Full Text Available Resumen La necrólisis epidérmica tóxica y el síndrome de Stevens-Johnson son reacciones cutáneas adversas graves a medicamentos e infecciones. Los corticoides se describen como una alternativa terapéutica, sin embargo, su uso es aún controvertido. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en múltiples bases de datos, identificamos cuatro revisiones sistemáticas que en conjunto incluyen once estudios primarios que responden la pregunta de interés. Extrajimos los datos y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Concluimos que no está claro si los corticoides disminuyen la mortalidad o la estadía hospitalaria en la necrólisis epidérmica tóxica y el síndrome de Stevens-Johnson porque la certeza de la evidencia es muy baja.

Mask topography effects need to be taken into consideration for more advanced resolution enhancement techniques in optical lithography. However, rigorous 3D mask model achieves high accuracy at a large computational cost. This work develops a combined source, mask and pupil optimization (SMPO) approach by taking advantage of the fact that pupil phase manipulation is capable of partially compensating for mask topography effects. We first design the pupil wavefront function by incorporating primary and secondary spherical aberration through the coefficients of the Zernike polynomials, and achieve optimal source-mask pair under the condition of aberrated pupil. Evaluations against conventional source mask optimization (SMO) without incorporating pupil aberrations show that SMPO provides improved performance in terms of pattern fidelity and process window sizes.

Full Text Available Introduction. Adie’s (tonic pupil is a neuro-ophthalmological disorder characterized by a tonically dilated pupil, which is unresponsive to light. It is caused by damage to postganglionic fibers of the parasympathetic innervation of the eye, usually by a viral or bacterial infection. Adie’s syndrome includes diminished deep tendon reflexes. Outline of Cases. We report data of a 59-year-old female with unequal pupil sizes. She complained of blurred vision and headache mainly while reading. She had a 35-year history of hepatitis B and liver cirrhosis. On exam, left pupil was mydriatic and there was no response to light and at slit lamp we saw segments of the sphincter constrict. We performed 0.125% pilocarpine test and there was a remarkable reduction of size in the left pupil. The second case is a 55-year-old female who was referred to the University Eye Clinic because of a headache and mydriatic left pupil. She had diabetes mellitus type 2, as well as hepatitis A virus 20 years earlier. On exam, the left pupil was mydriatic, with no response to light. Test with diluted pilocarpine was positive. Neurological examinations revealed no abnormality in either case so we excluded Adie’s syndrome. Conclusion. Adie’s tonic pupil is benign neuro-ophthalmological disorder of unknown etiology. Most patients commonly present no symptoms and anisocoria is noticed accidentally. Although the etiology is unknown, there are some conditions that cause tonic pupil. It may be a part of a syndrome in which tonic pupil is associated with absent deep tendon reflexes.

The subliminal mere exposure effect (SMEE) is the phenomenon wherein people tend to prefer patterns they have repeatedly observed without consciously identifying them. One popular explanation for the SMEE is that perceptual fluency within exposed patterns is misattributed to a feeling of preference for those patterns. Assuming that perceptual fluency is negatively correlated with the amount of mental effort needed to analyze perceptual aspects of incoming stimuli, pupil diameter should associate with SMEE strength since the former is known to reflect mental effort. To examine this hypothesis, we measured participants’ pupil diameter during exposure to subthreshold stimuli. Following exposure, a preference test was administered. Average pupil diameter throughout exposure was smaller when the SMEE was induced than when the SMEE was not induced. This supports the hypothesis that increasing perceptual fluency during mere exposure modulates autonomic nervous responses, such as pupil diameter, and eventually leads to preference. PMID:24587408

To the best of our knowledge, Stevens-Johnson syndrome (SJS) has not been reported previously as an adverse reaction to Malarone, which is a combination of atovaquone and proguanil hydrochloride used for antimalarial prophylaxis and therapy. We describe a 65-year-old patient who had SJS with typical clinical and histopathological findings associated with the use of Malarone prophylaxis for malaria. This report should alert physicians to this severe cutaneous reaction, and Malarone should be added to the list of drugs that can potentially cause SJS.

Full Text Available Aim: The aim of the study was to evaluate physical fitness of rural children and adolescents on the example of pupils of the School Complex in Ołdaki, Poland. Material and method: The study covered 79 pupils of grades IV–VI of the primary school and I–III of the lower secondary school of the School Complex in Ołdaki. The study used K. Zuchora’s Index of Physical Fitness and a diagnostic survey method based on the author-prepared questionnaire. Results: The study conducted among pupils of the School Complex in Ołdaki showed that physical fitness of children and adolescents from the countryside was at a relatively good level. Of the components of the Index of Physical Fitness, the worst results were obtained for abdominal muscle strength. However, the subjects showed very good flexibility, endurance and speed. Girls and boys obtained similar test results. Striking is the fact that the oldest subjects, i.e. pupils in grade III of the lower secondary school, obtained the worst results both in the entire test and in individual exercises. Conclusions: The pupils knew how to take care of their health; they were able to indicate the benefits of being physically active, were eager to take part in physical education classes and actively spent their free time. They mostly believed that they could eat healthy. Only a small percentage of pupils admitted to have had contact with stimulants and fast-foods, which was a confirmation of the fact that they were taking good care of their health. Fitness tests proved that the pupils’ fitness was at a satisfactory level. There was no noticeable difference in the results obtained by girls and boys, which indicated similar performance in all pupils. The evaluation of the pupils’ activity in their free time proved that they were more willing to spend it actively, most often playing football and cycling 2–3 times a week.

Studies on argument have found that participants tend to prefer explanations to evidence. This apparent bias toward explanation has been qualified recently by research that has found it to diminish with the availability of evidence. This study examines the use of explanation versus evidence in the context of argumentation with reference to the goals of particular argument situations. Seventy-nine eighth-grade pupils at a regular, urban middle school. The pupils read argumentation scenarios, each having the stated goal of either explaining or proving a claim. The pupils rated the degree to which each of two provided assertions (one a theoretical explanation, and the other evidence-based) helped achieve the goal of the argument. On a second task, the pupils chose which of the two assertions should be more effective in achieving the argument goal. On the third task, the pupils generated either an explanation or evidence for each of the argumentation scenarios. Pupils demonstrated sensitivity to the relative epistemic strength of explanation and evidence. They rated explanations as more advantageous in achieving the explanation goal, and evidence as more advantageous in achieving the proof goal. Conversely, however, when asked to generate or recall an explanation or evidence, pupils produced more explanations than evidence independent of the argumentation goal. The study refines the definition of argumentation context to include specific goals. Pupils were sensitive to the context of the argumentation situation (e.g.goals, availability of evidence). However, they appeared to have a disposition toward explanation when asked to produce an explanation or evidence-based justification.

Full Text Available Employing education production function approach, this article investigates the influences of school and pupil background factors on academic achievement of primary school pupils in Cambodia. Based on achievement data of 1,080 Grade 6 pupils from one rural and one semi-urban area, the study reveals that school and teacher quality exerts a considerable effect on pupils’ performance. Teachers’ experience and teacher guides are positively correlated with academic achievement, while instructional time loss is significantly associated with poor performance. In light of these results, policies to boost academic achievement of primary school pupils in Cambodia are discussed.

We measured pupil size in adult human subjects while they selectively attended to one of two surfaces, bright and dark, defined by coherently moving dots. The two surfaces were presented at the same location; therefore, subjects could select the cued surface only on the basis of its features. With no luminance change in the stimulus, we find that pupil size was smaller when the bright surface was attended and larger when the dark surface was attended: an effect of feature-based (or surface-based) attention. With the same surfaces at nonoverlapping locations, we find a similar effect of spatial attention. The pupil size modulation cannot be accounted for by differences in eye position and by other variables known to affect pupil size such as task difficulty, accommodation, or the mere anticipation (imagery) of bright/dark stimuli. We conclude that pupil size reflects not just luminance or cognitive state, but the interaction between the two: it reflects which luminance level in the visual scene is relevant for the task at hand.

To evaluate the effect of pupil size on image quality of a sectorial multifocal intraocular lens (IOL), the Lentis Mplus (Oculentis GmbH, Berlin, Germany), and the Acri.LISA IOL (Carl Zeiss Meditec, Jena, Germany). The authors measured the MTFs of the Lentis Mplus LS-312 IOL and the Acri.LISA 366D IOL with three different sizes of pupil diameters: 3, 4, and 5 mm. The MTF was calculated from the cross-line spread function recorded with the OPAL Vector System (Image Science Ltd., Oxford, UK) by using fast Fourier-transform techniques. In distance focus, the image quality provided by the Lentis Mplus IOL was better than that of the Acri. LISA IOL with all pupil diameters. In near focus, the MTF of the Acri.LISA IOL was better with a 3-mm pupil, but poor with larger pupils. The aberration effect was equal in both IOLs in distance focus, but in near focus and with a 3-mm pupil, the Acri.LISA IOL was less affected by the aberration than the Lentis Mplus IOL. The Lentis Mplus IOL provides better distance image quality than the Acri.LISA IOL, whereas the near image quality of the Acri.LISA IOL is better with small-pupil diameter. The sectorial design makes this IOL more suitable for patients with a pupil diameter greater than 3 mm. Copyright 2015, SLACK Incorporated.

The "High school class for students with special abilities in physics" was founded in Nis, Serbia (www.pmf.ni.ac.yu/f_odeljenje) in 2003. The basic aim of this project has been introducing a broadened curriculum of physics, mathematics, computer science, as well as chemistry and biology. Now, six years after establishing of this specialized class, and 3 years after the previous report, we present analyses of the pupils' skills in solving rather problem oriented test, as PISA test, and compare their results with the results of pupils who study under standard curricula. More precisely results are compared to the progress results of the pupils in a standard Grammar School and the corresponding classes of the Mathematical Gymnasiums in Nis. Analysis of achievement data should clarify what are benefits of introducing in school system track for gifted students. Additionally, item analysis helps in understanding and improvement of learning strategies' efficacy. We make some conclusions and remarks that may be useful for the future work that aims to increase pupils' intrinsic and instrumental motivation for physics and sciences, as well as to increase the efficacy of teaching physics and science.

The supply of students motivated to study engineering in higher education is critical to the sector. Results are presented from the 'Mindsets STEM Enhancement Project'. Fifty-seven new resources packs, designed to improve STEM education in Design and Technology, were given to schools across London. A modified Intrinsic Motivation Inventory questionnaire measured pupils' (n = 458) motivation towards technology. The results show that although pupils have positive reactions to the technology content within Design and Technology lessons, the type of STEM resources and lessons created through the project had made no significant difference on pupils' interest/enjoyment towards technology. This suggests stand-alone resources do not improve pupil motivation. The impact of this work to engineering higher education is that the existing levels and the inability to improve pupil motivation in technology at school could be a factor affecting the pursuit of a technology or engineering related education or career.

Ocular aberrations vary among subjects and under different conditions and are commonly analyzed expanding the wavefront aberration function in Zernike polynomials. In previous articles, explicit analytical formulas to transform Zernike coefficients of up to 7th order corresponding to an original pupil into those related to a contracted displaced new pupil are obtained. In the present paper these formulas are applied to 20 keratoconic corneas of varying severity. Employing the SN CT1000 topographer, aberrations of the anterior corneal surface for a pupil of semi-diameter 3 mm centered on the keratometric axis are evaluated, the relation between the higher-order root mean square wavefront error and the index KISA% characterizing keratoconus is studied and the size and centering of the ocular photopic natural pupil are determined. Using these data and the transformation formulas, new coefficients associated to the photopic pupil size are computed and their variation when coordinates origin is shifted from the keratometric axis to the ocular pupil centre is analyzed.

Full Text Available Migratory processes in southern Europe over the last two decades have brought about substantial changes to the ethnic makeup of secondary schools. Classrooms have increased in their complexity in terms of teaching, as there are pupils with different cultural and economic backgrounds and educational needs, but also in the relationships among the peer groups of pupils. What kinds of attitudes and relations can be found among the members of this culturally diverse pupil body? What kinds of views are held by the pupils about each other? The aim of this paper is to shed light on stereotypes and xenophobic attitudes towards immigrant pupils in secondary schools in Spain, principally among peer groups, and on how teachers address this multicultural classroom dynamic and complexity and any possible prejudices towards stereotypes and racist attitudes that surface inside the classroom. Relationships tend to be formed among peer groups of the same ethnicity and there is a marked rejection of pupils from Moroccan origin. Teachers are neither aware of pupils’ stereotypes nor of their own. As a consequence, they are not giving sufficient pedagogical responses to resolve arguments or disrespectful situations against immigrant pupils. This in turn is contributing, on the one hand, to racist and xenophobic societies (Banks 2011; Deusdad 2013. On the other hand, teachers’ low expectations of these immigrant pupils has had an effect on their academic achievements and on dropout rates (Deusdad 2009. The present study is based on 2196 questionnaires administered to pupils at 43 Spanish secondary schools. In-depth interviews with 54 secondary school teachers were also carried out, so as to understand teachers’ discourses and pedagogical resources.

"The British National Space Centre partnership has recognised for some time that Space and Astronomy are particularly attractive subjects for school students and that including these in the science curriculum can have a positive effect on student interest in science. Drivers are that the number of young people studying science and engineering subjects at A-level and beyond is declining; young people should have an understanding of the importance of science and technology to the world around them; and that UK space industry (including technology, engineering, space science, Earth observation science) must renew itself." BRINGING SPACE INTO SCHOOL Professor Martin Barstow, University of Leicester Published by PPARC on behalf of the British National Space Centre Partnership October 2005 "It has become more and more difficult to persuade young people to follow a career in STEM (Science, Technology, Engineering & Mathematics) subjects.

Astronomy is a multidisciplinary course bringing together elements of Science, Maths, Technology, Geography and History. It is hoped that the enthusiasm shown by the pupils will spill over into the mainstream subjects including maths.

Extension of space--time optics to objects whose transparency is a function of the temporal frequency v = c/lambda is examined. Considering the effects of such stationary pupils on white light waves, they are called temporal pupils. It is shown that simultaneous encoding both in the space and time frequency domains is required to record pupil parameters. The space-time impulse response and transfer functions are calculated for a dispersive nonabsorbent material. An experimental method providing holographic recording of the dispersion curve of any transparent material is presented

On examination, his visual acuity (VA was 20/20 in both eyes with a right superior oblique palsy. His pupillary reaction to light was intact while on near gaze there was no constriction of the pupils, bilaterally. The other two responses of the near gaze triad ie, convergence and accommodation were present. These findings were suggestive of an Inverse Argyll Robertson pupil (IARP, a rare entity in the literature. We could not find a specific cause attributable to this manifestation in this patient, though we feel it may be secondary to infiltration from Burkitt’s lymphoma and/or compression from elevated intracranial pressure of the efferent pupillary near reflex pathway.Keywords: Inverse Argyll Robertson pupil, Argyll Robertson pupil, pupillary abnormalities, Burkitt’s lymphoma

Evidence indicates that teachers can judge pupils on the basis of their physical appearance, including their body shape. Teacher bias towards obese pupils has been suggested as a potential pathway through which obese children attain relatively lower academic levels. The aim of this study was to investigate whether teachers' judgements of pupils' ability are influenced by the body shape of the child. The sample includes English, singleton children in state schools from the Millennium Cohort Study. The data were taken from the fourth wave of data collection, when the children were approximately 7 years old. In all, 5086/5072 children had teacher ability ratings of reading and maths. Logistic regression analyses were used to test whether teachers' perceptions of the child's reading and mathematics ability were influenced by the pupil's waist circumference, conditional upon cognitive test scores of reading and maths ability. After adjustment for cognitive test scores, no significant overall relationship was found between the pupil's waist circumference and the teacher's judgements of ability. No statistically significant differences were observed in the probability of being judged as above average after further adjustments were made for potential confounders. There is little evidence that teachers' judgements of pupils' ability are influenced by obesity.

The link between inappropriate parenting style and both bullying and victimization is well documented. However, it is not clear as to which kind of parenting style is associated with victimization. Furthermore, no studies have yet been conducted regarding the role of parental stress in bullying and victimization. This study aimed to examine the role of parenting styles and maternal stress in pupils' bullying and victimization. A total of 300 primary school pupils, enrolled in fourth and fifth grades, participated in the study. Initially, 100 noninvolved pupils were randomly selected using a multistage cluster sampling method. Then using a screening method, 100 bully pupils and 100 victimized peers were selected. Olweus Bullying Scale and teacher nomination were administered for screening these pupils. Baumrind Parenting Style Questionnaire and revised version of Abidin Parental Stress Index (short form) were also applied to all pupils in the study. Data were analyzed using discriminant function analysis. The findings showed that (a) with regard to parenting styles, significant differences were found among groups. Authoritarian parenting style could significantly predict pupils' bullying behavior, whereas victimization was predictable in families with permissive parenting style. In addition, noninvolved pupils were predicted to have authoritative parenting style. (b) Considering maternal stress, significant differences were observed across groups. Parents of bullies and victims were predicted to have higher maternal stress than noninvolved pupils. The implications of the study in relation to the role of mothers in bullying and victimization are discussed.

The author, a teacher of Naragakuen Junior High School-High School in Nara Prefecture, looks back the history of his given education about radiation to 3rd year pupils for the decade from 2002. The main theme of the education includes an actual radiometric study of the already attained, naturally cleaned-up radioactivity derived from A-bomb from the ground of Hiroshima City, and an asking investigation to know how many people misunderstand, as pupils have done so, that Hiroshima ground surface is still radio-contaminated. In 2011, pupils stayed at Fukushima, not Hiroshima. For the radiometric study, pupils first learn the movement of substances in the ground by rain with a model of naturally abundant 40 KCl using a simple radiometer, HAKARUKUN. Then in Hiroshuma, they measure the ambient dose at >600 spots to compare with the doses in other cities like Nara and Kyoto, and the beta-ray of A-bomb-exposed buildings and air dust to see the same half life as that measured in Nara. Their asking investigation revealed that 32.2% and 31.5% of Hiroshima citizen and the resident in other cities, respectively, misunderstand that radiation in the City is higher than other cities. These results have been presented at the conference for pupils mainly held by the Kinki Branch of Chemical Society of Japan. The author expects the exchange of radiological information between learned pupils and parents who have probably not been taught about radiation as its education has been absent during these 30 years. Though, the education is to be given to all pupils hereafter in Japan. (T.T.)
Full Text Available This article is about a new learning approach on an example of the pupils' research work in adefinite school subject. It is based on how to learn and take care for it. We think about a new role and a task for school library and a librarian in these activities.To satisfy all these goals means to improve general education through adopting basic knowledge. How to get to the information and how to use it?In this context school library and education system have the same goal: how to find what the pupil needs, when he needs it and where the information is. That means to teach him how to use all the sources of information and knowledge that will be needed in his work and life.The role of the librarian is always focused on encouragment of all school activities for pupils' purposes. He motivates, he's able to impose himself with his authority, he can always be contacted and wants more.Pupil who knows how to use all the sources of information and knowledge in the school library is ready for long-life learning and nowdays his professional and personal progress and success depend on it.

Research indicates that affective aspects of development provide a basis for autonomous learning. Pupils' liking for school may be a useful indicator of their relationships with teachers and the school. The aim of the research reported in this paper is to establish the properties of a measure of pupils' liking for school and to examine associations between this measure, pupils' experiences in lessons, their self-concepts and the amount of setting implemented in school. A stratified sample of 45 mixed secondary comprehensive schools was selected for the research. Schools represented a variety of ability-grouping practices in the lower school (Years 7-9), from completely mixed-ability to setting in all academic subjects. All Year 9 pupils were included in the sample. Pupils completed a questionnaire containing items on their self-concept, liking for school, and their perceptions of teaching in English, mathematics, and science. Data on pupils' gender, ethnic origin, social disadvantage and attainment was also collected. The properties and correlates of scales indicating pupils' liking for school and their perceptions of teaching in English, mathematics, and science are established. Liking for school is greater among girls, pupils with higher academic self-concepts, and those with more positive perceptions of teaching. Pupils are more positive about teaching they experience in English than in mathematics or science. When other variables are statistically controlled, there is no significant effect of the extent of ability grouping in the school as a whole. Affective aspects of learning should not be neglected in the drive to raise standards.

To investigate the authors' clinical impression that pupil size among myopic Jewish theological seminary students is different from pupil size of similar secular subjects. This cross-sectional study was conducted on 28 male Jewish theological seminary students and 28 secular students or workers who were matched for age and refraction. All participants were consecutively enrolled. Scotopic and photopic pupil size was measured by means of a Colvard pupillometer. Comparisons of various parameters between the groups were performed using the two-sample t-test, Fisher exact test, a paired-sample t-test, a two-way analysis of variance, and Pearson correlation coefficients as appropriate. The two groups were statistically matched for age, refraction, and visual acuity. The seminary students were undercorrected by an average of 2.35 diopters (D), while the secular subjects were undercorrected by only 0.65 D (pwork or of apparently characteristic undercorrection of the myopia is undetermined.

PurposeIt is purported that caffeine, an autonomic stimulant, affects visual performance. This study sought to assess whether caffeine intake was associated with changes in pupil size and/or amplitude of accommodation.Patients and methodsA double-masked, crossover study was conducted in 50 healthy subjects of age range 19 to 25 years. Subjects were randomized to treatments such that subjects consumed either 250 mg caffeine drink or vehicle on separate days. Amplitude of accommodation was measured by the push-up technique, and pupil size using a millimeter ruler fixed to a slit lamp biomicroscope in dim illumination (5 lux). Amplitude of accommodation and pupil size were taken at baseline, and at 30, 60 and 90 min time points post treatment. Repeated measures one-way ANOVA and paired t-test were used in analyzing data.ResultsAmplitude of accommodation and pupil size after caffeine intake were significantly greater than vehicle (Pcaffeine beverage was associated with significant increases in amplitude of accommodation and pupil size with time (Pcaffeine. This study suggests caffeine may have some influence on visual functions.

It has long been known that the diameter of human pupil enlarges with increasing effort during the execution of a task. This has been observed not only for purely mechanical effort but also for mental effort, as for example the computation of arithmetic problems with different levels of difficulty. Here we show that pupil dilation reflects changes in visuospatial awareness induced by attentional load during multi-tasking. In the single-task condition, participants had to report the position of lateralized, briefly presented, masked visual targets ("right", "left", or "both" sides). In the multitasking conditions, participants also performed additional tasks, either visual or auditory, to increase the attentional load. Sensory stimulation was kept constant across all conditions to rule out the influence of low-level factors. Results show that event-related pupil dilation strikingly increased with task demands, mirroring a concurrent decrease in visuospatial awareness. Importantly, pupil dilation significantly differed between two dual-task conditions that required to process the same number of stimuli but yielded differed levels of accuracy (difficulty). In contrast, pupil dilation did not differ between two conditions which were equally challenging but differed both in the modality of the dual task (auditory vs. visual) and in the number of stimuli to be attended. We conclude that pupil dilation genuinely reflects the top-down allocation of supramodal attentional resources. Copyright © 2015 Elsevier B.V. All rights reserved.
Full Text Available Purpose: to determine the theoretical basis for the formation of value orientations of pupils by means of school sports facilities abroad. Material: detailed analysis of 14 published sources. Results: found that in a foreign academic and journalistic literature dominates positive appreciation of cultural values of humanistic school sports in the formation of value orientations of pupils. Found that school sport abroad plays an important role not only as a means of forming the basic values - health, but also an important area of communication, the manifestations of social activity. As well as physical and mental form of organization and leisure facilities, excellent vehicle impacts on other values of human life: the authority and position in society, work, the structure of moral and volitional characteristics, aesthetic ideals and other value orientations. Conclusions: confirmed that the global experience of formation values pupil means school sports deserves attention and requires selective introduction into the domestic education system.

In this study, it is aimed to evaluate the mental workload by using a practical way which based on measuring pupil diameter changes that occurs under mental processing. To determine the mental effort required for each task, the video record of subjects` eyes are taken while they are performed different tasks and pupils were measured from the records. A group of university student, one female 9 males participated to the experiment. Additionally, NASA-TLX questionnaire is applied for the related mental tasks. For verification of results obtained from both indices, the correlation coefficient is calculated task base. The results show that there is weak and negative correlation between the indices on task base except 3rd task. By investigating pupil diameter measurements data too, it is founded that pupil dilates under mental workload during performing related tasks. For all tasks, pupil diameters of response periods increased according to reference baseline period.

This paper reports research about upper secondary school pupils' views about science investigations in school. Although researchers, teachers and examiners have expressed opinions about investigative work in science, there have been relatively few studies of pupils' experiences. The present study identified pupils' concerns about the limited time available, timing of the investigations, lack of familiarity with apparatus and the association of investigation almost exclusively with assessment, all factors which contributed to stress. One exceptional school apart, pupils perceived the teacher's role as a didactic supporter of strategies to maximise performance for assessment. We discuss these views and examine the potential for putting policy into practice.

The objectives of this study were to characterize volatile compounds and to determine the characteristic aromas associated with impact compounds in 4 fish sauces using solid-phase micro-extraction, gas chromatography-mass spectrometry, Osme, and gas chromatography olfactometry (SPME-Osme-GCO) coupled with Stevens' Power Law. Compounds were separated using GCMS and GCO and were identified with the mass spectral database, aroma perceived at the sniffing port, retention indices, and verification of compounds by authentic standards in the GCMS and GCO. Aromas that were isolated and present in all 4 fish sauce samples at all concentrations included fishy (trimethylamine), pungent and dirty socks (combination of butanoic, pentanoic, hexanoic, and heptanoic acids), cooked rice and buttery popcorn (2,6-dimethyl pyrazine), and sweet and cotton candy (benzaldehyde). All fish sauces contained the same aromas as determined by GCO and GCMS (verified using authentic standard compounds), but the odor intensity associated with each compound or group of compounds was variable for different fish sauce samples. Stevens' Power Law exponents were also determined using this analytical technique, but exponents were not consistent for the same compounds that were found in all fish sauces. Stevens' Power Law exponents ranged from 0.14 to 0.37, 0.24 to 0.34, 0.09 to 0.21, and 0.10 to 0.35 for dirty socks, fishy, buttery popcorn, and sweet aromas, respectively. This demonstrates that there is variability in Stevens' Power Law exponents for odorants within fish sauce samples.

As part of our research programme into facilitating improved ways of communicating with patients, especially about more sensitive clinical issues, we have been investigating whether there are any non-verbal methods that might aid this process. One such approach is to ask patients to choose a color in response to a particular question, for instance about health or psychological status, and for this purpose we developed the Manchester Color Wheel (MCW). This instrument consists of positive, neutral and negative colors and its validation in normal adults and those with anxiety or depression showed that it is responsive to change and reproducible. It also has the capacity to identify a positive frame of mind. We concluded that it might be a particularly useful instrument in adolescents and therefore this study aimed to validate it in a secondary school. 620 pupils (aged 11-17 years, mean age 14.0 years, 298 (48.1%) males, 322 (51.9%) females) at Sale Grammar School in Greater Manchester were asked to relate their mood to a MCW color and also complete the Hospital Anxiety Depression (HAD) questionnaire. To give these pupils an experience in science, 197 were divided into four subgroups for an 'experiment' to ascertain whether, compared to controls, a change in mood color choice could be induced by participation in sport, music or art activities. Although mood color and HAD depression score are unlikely to be measuring exactly the same psychological state, a negative mood color was chosen by 62.5% of HAD depressed compared to only 14.5% of HAD normal pupils (p color was chosen by 48.9% of normal and only 18.8% of depressed pupils (p colors which reached significance for sport and music. This study confirms the potential utility of the MCW to rapidly and easily assess a variety of health issues in large populations, including adolescents. Some of our results should also be of interest to educationalists.
Full Text Available Education is the key to increasing the knowledge and awareness of the general public on environmental issues at early ages, as envisaged in the concept of sustainable development. Hence, this study aims to discuss the sustainability practices among children at a Ministry of Education (MOE pre-school as a result of the implementation of environmental education through a formal curriculum. Sustainability practices of pupils in this study involves the concept of Reduce, Reuse and Recycle. Survey methods were used, which involved 500 pupils in MOE preschools in Hulu Langat district, Selangor Malaysia. Results showed that pre-school pupils practice the 3Rs only at a moderate level while the level of knowledge of sustainability was at a high level. The results also showed that there was no significant relationship between prolonged knowledge in practicing the 3Rs among pre-school students. Obviously the input given by the teacher in teaching and learning science was not aligned with sustainability activities such as the 3Rs. Space conservation practices using a structured curriculum platform should be utilised in order to produce citizens who are aware of sustainable development.

Characterization of the reaction violence of LX-04 explosive (85% HMX and 15% Viton A by weight) was obtained from Steven Impact Tests performed above the reaction initiation threshold. A 155 mm Howitzer propellant driven gas gun was used to accelerate the Steven Test projectiles in the range of approximately 170-300 m/s to react (ignite) the LX-04 explosive. Blast overpressure gauges, acoustic microphones, and high-speed photography characterized the level of high explosive reaction violence. A detonation in this velocity range was not observed and when comparing these results (and the Susan test results) with that of other HMX based explosives, LX-04 has a more gradual reaction violence slope as the impact velocity increases. The high binder content (15%) of the LX-04 explosive is believed to be the key factor to the lower level of violence

Time can be observed as a subjective, as well as an objective phenomenon which is a component of our life, and due to its communicational needs, it is standardized by temporal signs and symbols. The aim of this study was to determine the understanding of basic temporal relations of pupils with hearing impairments. We assumed that the knowledge of basic time relations is a precondition for the acquisition of knowledge that is connected with the understanding of the syllabus in regular school programs. Three groups of pupils have been examined: pupils with hearing impairments who attend the primary school of SUVAG Polyclinic under special condition, integrated hearing impaired pupils with minor additional difficulties who attend regular primary schools in Zagreb with a prolonged expert procedure and pupils of the control group. The subjects have been examined with a measuring instrument constructed by the expert team of the Polyclinic Suvag. Twenty nine subjects have been questioned, chronologically aged between 10 and 12.

Improvement of sex education in schools is a key part of the UK government's strategy to reduce teenage pregnancy in England. We examined the effectiveness of one form of peer-led sex education in a school-based randomised trial of over 8000 pupils. 29 schools were randomised to either peer-led sex education (intervention) or to continue their usual teacher-led sex education (control). In intervention schools, peer educators aged 16-17 years delivered three sessions of sex education to 13-14 year-old pupils from the same schools. Primary outcome was unprotected (without condom) first heterosexual intercourse by age 16 years. Analysis was by intention to treat. By age 16 years, significantly fewer girls reported intercourse in the peer-led arm than in the control arm, but proportions were similar for boys. The proportions of pupils reporting unprotected first sex did not differ for girls (8.4% intervention vs 8.3% control) or for boys (6.2% vs 4.7%). Stratified estimates of the difference between arms were -0.4% (95% CI -3.7% to 2.8%, p=0.79) for girls and -1.4% (-4.4% to 1.6%, p=0.36) for boys. At follow-up (mean age 16.0 years [SD 0.32]), girls in the intervention arm reported fewer unintended pregnancies, although the difference was borderline (2.3% vs 3.3%, p=0.07). Girls and boys were more satisfied with peer-led than teacher-led sex education, but 57% of girls and 32% of boys wanted sex education in single-sex groups. Peer-led sex education was effective in some ways, but broader strategies are needed to improve young people's sexual health. The role of single-sex sessions should be investigated further.

Over the past two decades there have been major developments in deaf education in many countries. Medical and technical advances have made it possible for more deaf children to hear and speak successfully. Most deaf pupils learn in ordinary classes in mainstream schools. In this article we explore...... patterns of achievements of deaf pupils to see if these reforms had improved attainment outcomes. International surveys such as PISA do not include deaf pupils. This article describes two independent large-scale surveys about deaf pupils in Sweden and Scotland. The similar results from both countries show...... that deaf children, after two decades of social reform and technical advances, still lag behind their hearing peers. The results also show how large-scale surveys can contribute to a greater understanding of educational outcomes in a small, vulnerable group and make it possible to continue to reform...
This paper argues that school grades cannot be interpreted solely as a reward for a given school performance, since they also reflect teachers' assessments of pupils.

Full Text Available Background. Today, young people are more focused on getting education as such, without taking into account the profession. The relevance of this study is the identification of the level of professional self-determination of senior pupils, the mechanisms of formation of professional preferences. The article contains the concept and content of professional self-determination in adolescence; the results of the study on the formation of professional self-determination in senior pupils are presented. The study conducted among 9th grade pupils of secondary schools has revealed that the further gradual self-determination of the future specialty depends not only on psychological readiness for conscious choice. Materials and methods. The study involved 982 pupils of secondary schools in Ukraine. To study the level of formation of professional readiness, there was conducted a survey on the developed questionnaire. Statistical analysis was carried out using MS Excel and SPSS 17. Results. The results showed that professional intents of 9-graders are a key feature for solving the problem of high school selection and future careers. But for most students, these intentions are contradictory due to objective reasons. Radio, television, books don’t have a significant impact on the choice of professional self-determination. Conclusions. The conducted survey is self-sufficient for the analysis of professional orientation. But the choice of profession by the students is influenced by many factors. Therefore, carrying out the studies on vocational guidance requires an integrated approach.

Metronidazole alone rarely causes Stevens-Johnson syndrome (SJS). We present a case of an elderly male patient who, following metronidazole use, developed neurological symptoms followed by pain and blisters on both soles, erythema of face and neck, scrotal itching and erosion, and hemorrhagic encrustation around the lips and oral mucous membrane. Initial neurological symptoms followed by mucocutaneous manifestation of SJS following metronidazole use is probably a new presentation of this case.

Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening mucocutaneous adverse drug reactions with a high morbidity and mortality that require immediate medical care. The various immunomodulatory treatments include systemic corticosteroids, cyclosporine, intravenous immunoglobulin, cyclophosphamide, plasmapheresis and tumor necrosis factor-α inhibitors. The ideal therapy of Stevens-Johnson syndrome/toxic epidermal necrolysis still remains a matter of debate as there are only a limited number of studies of good quality comparing the usefulness of different specific treatments. The aim of this article is to comprehensively review the published medical literature and frame management guidelines suitable in the Indian perspective. The Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) assigned the task of preparing these guidelines to its special interest group on cutaneous adverse drug reactions. The group performed a comprehensive English language literature search for management options in Stevens-Johnson syndrome/toxic epidermal necrolysis across multiple databases (PubMed, EMBASE, MEDLINE and Cochrane) for keywords (alone and in combination) and MeSH items such as "guidelines," "Stevens-Johnson syndrome," "toxic epidermal necrolysis," "corticosteroids," "intravenous immunoglobulin," "cyclosporine" and "management." The available evidence was evaluated using the strength of recommendation taxonomy and graded using a three-point scale. A draft of clinical recommendations was developed on the best available evidence which was also scrutinized and critically evaluated by the IADVL Academy of Dermatology. Based on the inputs received, this final consensus statement was prepared. A total of 104 articles (meta-analyses, prospective and retrospective studies, reviews [including chapters in books], previous guidelines [including Indian guidelines of 2006] and case series) were critically evaluated and the evidence

Eye tracker is an important instrument for research in psychology, widely used in attention, visual perception, reading and other fields of research. Because of its potential function in human-computer interaction, the eye gaze tracking has already been a topic of research in many fields over the last decades. Nowadays, with the development of technology, non-intrusive methods are more and more welcomed. In this paper, we will present a method based on the shape of pupil image to estimate the gaze point of human eyes without any other intrusive devices such as a hat, a pair of glasses and so on. After using the ellipse fitting algorithm to deal with the pupil image we get, we can determine the direction of the fixation by the shape of the pupil.The innovative aspect of this method is to utilize the new idea of the shape of the pupil so that we can avoid much complicated algorithm. The performance proposed is very helpful for the study of eye gaze tracking, which just needs one camera without infrared light to know the changes in the shape of the pupil to determine the direction of the eye gazing, no additional condition is required.

Introduction. Taking psychoactive substances constitutes a significant problem for Public Health, particularly in preventing drug abuse and addiction. Objectives. To estimate the amount and incidence of drug consumption in middle and high school pupils, including the circumstances in which drug taking first started, and to determine pupils' knowledge about the consequences of taking psychoactive substances and designer drugs (DDs). Materials and methods. A randomised study was conducted throughout Poland on 9,360 pupils attending middle school (junior high school) in 2009 and 7,971 pupils from middle and high school pupils in 2011. The survey consisted of a questionnaire devised by the Chief Sanitary Inspectorate (GIS) and the replies obtained were subject to the relevant statistical analyses. Results. Drug taking was found to have increased between 2009-2011, especially among those attending high school; proportionally rising from 4% - 11%. The numbers who had ever taken designer drugs were 3% for middle school pupils and 4% from high school. Conclusions. 1) Adolescent drug consumption has increased, particularly in those of older age and in boys. 2) Despite the only brief interval for which designer drugs were legal, they have gained high popularity among the young. 3) Adolescents have insufficient knowledge about the dangers of using DDs. 4) Faced with the growing threat of a dynamic designer drug market, appropriate counter-measures in education and prevention are therefore necessary.
Full Text Available Objective: Monnose-Binding lectin (MBL appears to play an important role in the immune system. The genetic polymorphisms in the MBL2 gene can result in a reduction of serum levels, leading to a predisposition to recurrent infection. The aim of this study is to investigate the influence of a polymorphism in codon 54 of the MBL2 gene on the susceptibility to Erythema Multiforme, Stevens-Johnson Syndrome and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis Overlap Syndrome (EM, SJS and SJS/TEN overlap syndrome. Material and Methods: Our study included 64 patients who were clinically and/or histopathologically diagnosed with EM, SJS, and SJS/TEN overlap syndrome and 66 healthy control subjects who were genotyped for the MBL2 gene codon 54 polymorphism using the PCR-RFLP method. For all statistical analyses, the level of significance was set at p<0.05. Results: The prevalence of the B allele was 18% in the EM, SJS and SJS/TEN patient groups and 13% in the control group. No significant differences in allele frequencies of any polymorphism were observed between the patient and control groups, although the B allele was more frequent in the patient groups (p=0.328.Conclusion: Our results provide no evidence of a relationship between MBL2 gene codon 54 polymorphism and the susceptibility to EM, SJS and SJS/TEN overlap syndrome. However, these findings should be confirmed in studies with a larger sample size.

To report successful treatment of refractive glaucoma in a patient submitted to osteo-odonto-keratoprosthesis surgery for Stevens-Johnson syndrome. An interventional case report. The patient is a 62-year-old Indian man with known Stevens-Johnson syndrome since 1972 secondary to tetracycline therapy, with bilateral dry eye and corneal blindness. He underwent symblepharon release surgery with mucous membrane graft in both eyes. Osteo-odonto-keratoprosthesis surgery was later performed on the left eye. He was submitted to 2 Ahmed valve implants to control secondary glaucoma but visual fields continued to worsen; hence, he underwent endoscopic 140° cyclophotocoagulation with a good control of IOP. Endoscopic cyclophotocoagulation as alternative treatment provides good results in refractory glaucoma after osteo-odonto-keratoprosthesis surgery.

Full Text Available This paper is a part of a broader research in the field of development of different intellectual abilities in primary schools. Using a transverse - longitudinal research strategy, the pupils from nine to fifteen years of age are observed in order to find answers to the following questions: 1 Do the important developmental changes in the figural-perceptual abilities occur in this developmental period? 2 Is the pace of changes in these abilities the same at all ages, grades? 3 Do the developmental changes in these abilities depend on the type of tests, that is, mental operations which register the applied tests? Figural-perceptual abilities are defined as the ability to identify the elements in space, to imagine and transform the elements in space, the ability for spatial reasoning, perceptual shaping flexibility, the ability of eduction of relations and correlates, the ability to identify the elements that are injected into the right material, the ability to notice the difference in the forms and dimensions of the characters, speed observations of similarities and differences between elements in the field of perception. The measurement (assessment of these abilities was performed with the help of 11 tests of intellectual abilities of the figural content. The individual progresses as baseline data were used for the data analysis. The progresses of the subjects were compared with the analysis and the results are the following: 1 The pupils from third to eighth grade showed positive changes in the figurative perceptive abilities. This is shown in all the tests that were used and progresses are statistically significant in all tests 2 There is a tendency that the pupils in the sixth grade made the best progress, and the seventh-grade pupils made the least progress. 3 However, when the progresses are compared in certain tests, then significant differences in the pace of development of these abilities are determined. Namely, the pupils in the higher

Background: Stevens Johnson Syndrome and Erythema Multiforme are hypersensitivity skin reactions generally arising in the context of multiple causes. Radiation therapy is considered to be one of these causes, although most reports are hindered by concomitant medications. Aim: The aim of this paper was to present a case of Stevens Johnson Syndrome arising in a patient undergoing gynaecological brachytherapy with an unusual presentation. Case:We describe a case of a 56-year-old woman with endometrial cancer undergoing adjuvant gynaecological radiotherapy. While undergoing a gynaecological brachytherapy boost, she developed bilateral conjunctivitis that progressed to oral mucositis and pruritic erythema with sloughing of the skin on her arms and legs but not the torso or irradiated fields (namely the vaginal mucosa). Conclusion: This case illustrates the association of RT/SJS; however, it also raises the question of patients undergoing RT being more susceptible to SJS as opposed to a direct cause of the disease.

Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin. These cells receive afferent inputs from rods and cones, which provide inputs to the postreceptoral visual pathways. It is unknown, however, how melanopsin activation is integrated with postreceptoral signals to control the pupillary light reflex. This study reports human flicker pupillary responses measured using stimuli generated with a five-primary photostimulator that selectively modulated melanopsin, rod, S-, M-, and L-cone excitations in isolation, or in combination to produce postreceptoral signals. We first analyzed the light adaptation behavior of melanopsin activation and rod and cones signals. Second, we determined how melanopsin is integrated with postreceptoral signals by testing with cone luminance, chromatic blue-yellow, and chromatic red-green stimuli that were processed by magnocellular (MC), koniocellular (KC), and parvocellular (PC) pathways, respectively. A combined rod and melanopsin response was also measured. The relative phase of the postreceptoral signals was varied with respect to the melanopsin phase. The results showed that light adaptation behavior for all conditions was weaker than typical Weber adaptation. Melanopsin activation combined linearly with luminance, S-cone, and rod inputs, suggesting the locus of integration with MC and KC signals was retinal. The melanopsin contribution to phasic pupil responses was lower than luminance contributions, but much higher than S-cone contributions. Chromatic red-green modulation interacted with melanopsin activation nonlinearly as described by a "winner-takes-all" process, suggesting the integration with PC signals might be mediated by a postretinal site.

information on attitudes towards the issue of sport and health as well as on sporting activities. In this contribution, we concentrate on the influence of parents and schools on the fitness and motor competencies of the children. The results of the test and the survey clearly showed correlations between...... the fitness level of the pupils and the education level of the parents. According to our results, fitness and physical skills are, at least to a certain extent, socially inherited. The fitness differences found in the different schools can be explained partly by the different social back ground......Health and fitness among children and adolescents is a subject currently receiving public attention. This article focuses on the fitness of German pupils (third and fourth grades) in five schools in Berlin with widely differing social catchment areas as well as children from differing social...

To report the pattern of ocular trauma among school pupils in Ilorin, Nigeria, a cross sectional survey of primary school children in 10 randomly selected primary schools within Ilorin, Nigeria was carried out between July 2005 and January 2006. Relevant ocular history and basic ocular examinations were carried out on the children that were selected from a multi-stage sampling process. Diagnosis of ocular trauma was based on historical recollection together with corroborating ocular signs among affected pupils. Ocular trauma was found among 11 (8 boys and 3 girls) out of 1393 (0.8%) pupils and their ages ranged from 5 to 13 years. The trauma related ocular pathology found among the 11 pupils included unilateral phthisis bulbi (2, 0.14%), couching (1, 0.07%) and retinal detachment (1, 0.07%) all leading to blindness in the affected eyes. There was also a unilateral visual impairment caused by traumatic optic atrophy. Others included eyelid bruises (2, 0.14%) and one pupil (0.07%) each with hyphema, eyelid ecchymosis, eyelid laceration, and subconjunctival haemorrhage. The ocular trauma occurred following unsupervised play (4, 36.40%), corporal punishment at school and at home (3, 27.30%), fight (2, 18.20%), home accident (1, 9.10%) and couching (1, 9.10%). School pupils can lose vision to preventable traumatic eye injuries both at school and at home. Measures to minimize ocular trauma both in the home and at school are advocated.

Dividing attention over two streams of speech strongly decreases performance compared to focusing on only one. How divided attention affects cognitive processing load as indexed with pupillometry during speech recognition has so far not been investigated. In 12 young adults the pupil response was recorded while they focused on either one or both of two sentences that were presented dichotically and masked by fluctuating noise across a range of signal-to-noise ratios. In line with previous studies, the performance decreases when processing two target sentences instead of one. Additionally, dividing attention to process two sentences caused larger pupil dilation and later peak pupil latency than processing only one. This suggests an effect of attention on cognitive processing load (pupil dilation) during speech processing in noise. Copyright © 2014 The Authors. Published by Elsevier B.V. All rights reserved.

Technological advances and accessibility to information on the internet have opened a new channel of pupils that are being taught by students throughout the country. Students, full of motivation and a will to learn and teach, have understood that this way is good for them – enabling them to profit from a side job and take advantage of the knowledge they have accumulated in their degree. Holon Institute of Technology (“HIT”) developed a new program at the Faculty of Electrical Engineering. The Renewable Energy program gives the students technical and practical aspects of energy use (technology and methodology of the study) and energy efficiency. The program also deals with minimizing the environmental impacts of energy use, as well as with energy economy and environmental policy. The entrance of students to the field of teaching pupils while still in their studies brings many advantages, such as: fresh knowledge, motivation to teach, and innovative, out of the ordinary methods that arouse interest in the pupils and intrigue them.
Full Text Available Abstract: The influence on learning outcomes of interpersonal interaction amongst teachers, pupils and parents is the subject of an inquiry that took this researcher on a voyage from the qualitative to the quantitative side of the “methodological divide”, and back again. This paper presents findings from first phase of the research, which included a quantitative survey to examine how learning and teaching experience for violin pupils was influenced by the interpersonal dynamics of responsiveness and control, within pupilparent and pupil-teacher relationships. As part of the survey pupils were asked to draw pictures of their violin lessons. It was thought that the pictures might reveal pupils’ perceptions of their experience of learning an instrument and that the pictures would add depth to the quantitative scales that measured interpersonal mechanisms and pupil outcomes. The pictures were subjected to content analysis and coded accordingly. These codes were matched with pupil artists’ scores for control and responsiveness, as well as with their scores for outcomes that included enjoyment of music, personal satisfaction, self esteem, self efficacy, friendship, motivation and musical attainment. Analysis of variance was computed in order to test the null hypotheses that a pupil-teacher-parent interpersonal behaviour (control and responsiveness was not represented in their pictures and b pupil outcomes were not reflected in their depictions of violin lessons. This paper presents the results of this analysis, thus addressing the question of whether the pictures could be accepted as telling a credible and coherent story about pupils’ perceptions of learning the violin.

To investigate the effect of pupil size on visual acuity in pseudophakic monovision. For the simulation, a modified Liou-Brennan model eye was used. The model eye was designed to include a centered optical system, corneal asphericity, an iris pupil, a Stiles-Crawford effect, an intraocular lens, and chromatic aberration. Calculation of the modulation transfer function (MTF) was performed with ZEMAX software. Visual acuity was estimated from the MTF and the retinal threshold curve. The sizes of the entrance pupil were 2.0, 2.5, 3.0, and 4.0 mm. Decreasing pupil diameter and increasing myopia progressively improved near visual acuity. For an entrance pupil size of 2.5 mm and a refractive error of -1.50 diopters, the logMAR value (Snellen; metric) in the non-dominant eye at 40 cm was 0.06 (20/23; 6/6.9). Knowledge of the patient's pupil diameter at near fixation can assist surgeons in determining the optimum degree of myopia for successful monovision.

Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of her symptoms was noted, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge. After 48 months, she remained refractory to medical management and definitive surgical treatment with bilateral oophorectomy was performed. Autoimmune progesterone dermatitis is a challenging diagnosis owing to its rarity and variety of clinical presentations. Treatment centers on suppression of endogenous progesterone and avoidance of exogenous triggers. When these modalities fail, surgical management must be undertaken.

Ocular reflectors enhance eye sensitivity in dim light, but can produce reflected eyeshine when illuminated. Some fish can occlude their reflectors during the day. The opposite is observed in cryptic sit-and-wait predators such as scorpionfish and toadfish, where reflectors are occluded at night and exposed during the day. This results in daytime eyeshine, proposed to enhance pupil camouflage by reducing the contrast between the otherwise dark pupil and the surrounding tissue. In this study, we test this hypothesis in the scorpionfish Scorpaena porcus and show that eyeshine is the result of two mechanisms: the previously described Stratum Argenteum Reflected (SAR) eyeshine, and Pigment Epithelium Transmitted (PET) eyeshine, a newly described mechanism for this species. We confirm that the ocular reflector is exposed only when the eye is light-adapted, and present field measurements to show that eyeshine reduces pupil contrast against the iris. We then estimate the relative contribution of SAR and PET eyeshine to pupil brightness. Visual models for different light scenarios in the field show that daytime eyeshine enhances pupil camouflage from the perspective of a prey fish. We propose that the reversed occlusion mechanism of some cryptobenthic predators has evolved as a compromise between camouflage and vision.
Full Text Available Purpose: To assess and compare the effects of contact lens-based artificial pupil design and contralateral balanced multifocal contact lens combination (CBMCLC on visual performance. Methods: This randomized crossover study conducted at the University of Valencia, Spain included 38 presbyopic patients using an artificial pupil contact lens in the nondominant eye and a CBMCLC. After a month of lens wear, the binocular distance visual acuity (BDVA, binocular near visual acuity (BNVA, defocus curve, binocular distance, and near contrast sensitivity and near stereoacuity (NSA were measured under photopic conditions (85 cd/m2. Moreover, BDVA and binocular distance contrast sensitivity were examined under mesopic conditions (5 cd/m2. Results: Visual acuity at an intermediate distance and near vision was better with the CBMCLC than with the artificial pupil (p<0.05. Statistically significant differences were found in contrast sensitivity between the two types of correction for distance (under mesopic conditions and for near vision, with the CBMCLC exhibiting better results in both cases (p<0.05. The mean NSA values obtained for the artificial pupil contact lens were significantly worse than those for the CBMCLC (p=0.001. Conclusion: The CBMCLC provided greater visual performance in terms of intermediate and near vision compared with the artificial pupil contact lens.

Full Text Available Abstract Background As part of our research programme into facilitating improved ways of communicating with patients, especially about more sensitive clinical issues, we have been investigating whether there are any non-verbal methods that might aid this process. One such approach is to ask patients to choose a color in response to a particular question, for instance about health or psychological status, and for this purpose we developed the Manchester Color Wheel (MCW. This instrument consists of positive, neutral and negative colors and its validation in normal adults and those with anxiety or depression showed that it is responsive to change and reproducible. It also has the capacity to identify a positive frame of mind. We concluded that it might be a particularly useful instrument in adolescents and therefore this study aimed to validate it in a secondary school. Methods 620 pupils (aged 11–17 years, mean age 14.0 years, 298 (48.1% males, 322 (51.9% females at Sale Grammar School in Greater Manchester were asked to relate their mood to a MCW color and also complete the Hospital Anxiety Depression (HAD questionnaire. To give these pupils an experience in science, 197 were divided into four subgroups for an ‘experiment’ to ascertain whether, compared to controls, a change in mood color choice could be induced by participation in sport, music or art activities. Results Although mood color and HAD depression score are unlikely to be measuring exactly the same psychological state, a negative mood color was chosen by 62.5% of HAD depressed compared to only 14.5% of HAD normal pupils (p Conclusion This study confirms the potential utility of the MCW to rapidly and easily assess a variety of health issues in large populations, including adolescents. Some of our results should also be of interest to educationalists.

Full Text Available The goal of this empirical study is to describe power constellations that are generated in interactions between Roma pupils and their teachers, and also to summarize the basic findings of this research and to point out some real situations that can occur during the teaching lessons. The first part of the thesis describes the differences in the social interaction of Roma pupils. The second part is focused on the authority of the teachers and also on using this authority during the lessons. The third part is focused on pupils‘ strategies that are created based on the requirements of teachers. The basic findings of the research are selected in the methodological section. The research survey revealed five power constellations, which are the subject of this empirical study. The empirical study suggests how teachers and pupils define and shape relationships. From the present paper, a lot of influences are involved in the formation of power constellation, ranging from the personality of the teachers, socializing in school, through family upbringing to cultural differences.

Pupils can truly serve as windows to the mind. Since the early part of the last decade, pupillometry, the study of pupils in response to cognitive tasks, have gained traction in psychophysiological studies. Muscles of the iris work in tandem with the autonomic nervous system in response to light condition to either dilate or contract the pupil, usually between 2 to 7 mm. Along with this response to light conditions, the pupils also contract or dilate in response to emotional or mental response. Therefore, for a cognitive task, if the ambient brightness is controlled, pupil dilation reflects the cognitive load associated with the task. Simple tasks such as counting, memorizing, multiplying and visual searching have been found to have pupillometry profiles reflective of the cognitive load involved with such tasks. In this study, we investigate whether pupil diameter can be used for education research where tasks can be more complex. In particular, we look at two specific types of tasks common in geoscience and several other STEM fields: graph reading and spatial problem solving.

Past research suggests that men perceive women with large pupils as especially attractive. We employed an innovative methodology to examine whether this effect influences consumer decision-making. A popular psychology book was published with two slightly different front covers. Both covers contained the same photograph of a woman; however, the woman's pupils on one cover were digitally enlarged. Readers indicated whether they were male or female, and whether they possessed the cover with small or large pupils. A significantly greater percentage of men than women had chosen the cover with the large pupils. None of the participants who attempted to guess the nature of the experiment was correct, suggesting that the influence exerted by pupil size was unconscious. These findings provide further support for the notion that people's judgments are unconsciously swayed by pupil size, and demonstrate that this effect operates in a real world setting.

Pupillometry provides an accessible option to track working memory processes with high temporal resolution. Several studies showed that pupil size increases with the number of items held in working memory; however, no study has explored whether pupil size also reflects the quality of working memory representations. To address this question, we used a spatial working memory task to investigate the relationship of pupil size with spatial precision of responses and indicators of reliance on generalized spatial categories. We asked 30 participants (15 female, aged 19-31) to remember the position of targets presented at various locations along a hidden radial grid. After a delay, participants indicated the remembered location with a high-precision joystick providing a parametric measure of trial-to-trial accuracy. We recorded participants' pupil dilations continuously during task performance. Results showed a significant relation between pupil dilation during preparation/early encoding and the precision of responses, possibly reflecting the attentional resources devoted to memory encoding. In contrast, pupil dilation at late maintenance and response predicted larger shifts of responses toward prototypical locations, possibly reflecting larger reliance on categorical representation. On an intraindividual level, smaller pupil dilations during encoding predicted larger dilations during late maintenance and response. On an interindividual level, participants relying more on categorical representation also produced larger precision errors. The results confirm the link between pupil size and the quality of spatial working memory representation.

To explore the association between types of unintentional injuries and influential factors among rural rear pupils. The multistage stratified sampling method was used to select the study participant and thus 594 rural pupils were sampled, 292 rear pupils were confirmed and measured with unintentional injuries and influential factors of rural rear pupils scale. Binary logistic regression analysis indicate that the risk facts related to unintentional injury were left-behind status (OR = 2.68, 95% CI 1.06-6.79), gender (OR = 5.12, 95% C2.68-9.79) and surrounding environment (OR = 3.44, 95% CI 1.37-8.70). Correspondence analysis showed living with father, middle personality and low age were related possibly with traffic accident injury. Living with grandparents, extrovert personality and elder pupils were related possibly with unintentional falls injury. Living with mother, introvert personality and middle-age pupils were related possibly with animmal injury. The personality, ages and guardian types of rural rear pupils are correlated with types of unintentional injuries.

Background: This article reports on an evaluation study of a project seeking to develop the use of position-linked datalogging with primary pupils in environmental science contexts. Purpose: The study sought to find out the extent to which the project had developed: (1) participant teachers' confidence in using datalogging as an everyday part of their science teaching; (2) pupils' abilities to collect and interpret relevant environmental monitoring data; and (3) the use of scientific data within environmental education in the project schools. Programme description: The project used software which integrates data from Global Positioning System (GPS) with sensor data collected outdoors to produce Google Earth visualisations of environmental quality in each school's locality. Sample: Phase 1 involved 10 primary schools in the South West of England (2008-9), and phase 2 was implemented in six primary schools in Greater London during 2010. All pupils in the 9-10-year-old age range participated to some extent (N ≈ 450) and each school identified a focus group of between two and four pupils (n = 38) together with two members of staff (n = 32) to be more closely involved in the project. Design and methods: The evaluation adopted a multi-method approach, drawing upon documentary sources (n = 40); observations of continuing professional development (CPD) cluster days (n = 8) and dissemination events (June 2009 and January 2011): baseline pupil assessment tasks (n = 291) and teachers' baseline questionnaire (n = 25) in September 2008 and March 2010; classroom observations; samples of pupil work (n = 31); end-of-project pupil assessment (n = 38) and teachers' and pupils' responses to the project (n ≈ 180) in June 2009 and December 2010; and a longitudinal evaluation in February 2012. Results: Datalogging had become a regular feature of practical science in nearly all project schools up to 30 months after the end of the project, but the use of position-linked logging had

To describe a new technique for implantation of capsule-fixated intraocular lenses (IOLs) (FEMTIS; Oculentis, Berlin, Germany) in patients with small pupils. In 4 eyes with small pupils, an anterior capsule-fixated IOL was implanted into the capsular bag after femtosecond laser treatment. The two large and two small flaps of the IOL were elevated to the front of the iris and the anterior capsule. Finally, the iris was flipped over the flaps to ensure a fixation of the capsule inside of the capsulotomy. In all cases, the implantation of anterior capsule-fixated IOLs was possible. No complications occurred during surgery or within the first months after surgery. With the described technique, capsulefixated IOLs can be implanted in eyes with small pupil easily and safely. This type of IOL has great potential to improve the refractive outcome by better prediction of the postoperative IOL position and eliminating IOL rotation after cataract surgery.

The direct imaging and characterization of Earth-like planets is among the most sought-after prizes in contemporary astrophysics, however current optical instrumentation delivers insufficient dynamic range to overcome the vast contrast differential between the planet and its host star. New opportunities are offered by coherent single mode fibers, whose technological development has been motivated by the needs of the telecom industry in the near infrared. This paper presents a new vision for an instrument using coherent waveguides to remap the pupil geometry of the telescope. It would (i) inject the full pupil of the telescope into an array of single mode fibers, (ii) rearrange the pupil so fringes can be accurately measured, and (iii) permit image reconstruction so that atmospheric blurring can be totally removed. Here we present a laboratory experiment whose goal was to validate the theoretical concepts underpinning our proposed method. We successfully confirmed that we can retrieve the image of a simulated astrophysical object (in this case a binary star) though a pupil remapping instrument using single mode fibers.

Chronic mydriasis was induced in six kittens (four monocular, two binocular) and two adult cats (both monocular) by the daily topical application of atropine. Both the kittens and the adult cats were atropinized for a 13-week period with the treatment regimen beginning at the time of eye opening for the kittens. Pupil size measurements, obtained 1 year after the atropinization were discontinued, revealed that, although the pupils of the adult cats were normal, the pupils of the kittens' treated eyes were consistently smaller than pupils in control eyes. The status of the muscarinic receptors in the kittens' irides was investigated using 3 H-QNB binding assays. In comparison with iris muscle homogenates from the control eyes, those from the treated eyes demonstrated an eightfold increase in the number of receptor binding sites. The results indicate that pupil size can be altered permanently by chronic mydriasis initiated early in the life of a kitten and that the permanent change in pupil size may result, in part, from a type of permanent supersensitivity response in the muscle following chronic blockade of muscarinic transmission by atropine
Full Text Available The response time (RT based Concealed Knowledge Test (CKT has been shown to accurately detect participants’ knowledge of mock-crime related information. Tests based on ocular measures such as pupil size and blink rate have sometimes resulted in poor classification, or lacked detailed classification analyses. The present study examines the fitness of multiple pupil and blink related responses in the CKT paradigm. To maximize classification efficiency, participants’ concealed knowledge was assessed using both individual test measures and combinations of test measures. Results show that individual pupil-size, pupil-slope, and pre-response blink-rate measures produce efficient classifications. Combining pupil and blink measures yielded more accuracy classifications than individual ocular measures. Although RT-based tests proved efficient, combining RT with ocular measures had little incremental benefit. It is argued that covertly assessing ocular measures during RT-based tests may guard against effective countermeasure use in applied settings. A compound classification procedure was used to categorize individual participants and yielded high hit rates and low false-alarm rates without the need for adjustments between test paradigms or subject populations. We conclude that with appropriate test paradigms and classification analyses, ocular measures may prove as effective as other indices, though additional research is needed.

While judging their sensory environments, decision-makers seem to use the uncertainty about their choices to guide adjustments of their subsequent behaviour. One possible source of these behavioural adjustments is arousal: decision uncertainty might drive the brain's arousal systems, which control global brain state and might thereby shape subsequent decision-making. Here, we measure pupil diameter, a proxy for central arousal state, in human observers performing a perceptual choice task of varying difficulty. Pupil dilation, after choice but before external feedback, reflects three hallmark signatures of decision uncertainty derived from a computational model. This increase in pupil-linked arousal boosts observers' tendency to alternate their choice on the subsequent trial. We conclude that decision uncertainty drives rapid changes in pupil-linked arousal state, which shape the serial correlation structure of ongoing choice behaviour.

Monitoring pupil and blink dynamics has applications in cognitive load measurement during human-machine interaction. However, accurate, efficient, and robust pupil size and blink estimation pose significant challenges to the efficacy of real-time applications due to the variability of eye images, hence to date, require manual intervention for fine tuning of parameters. In this paper, a novel self-tuning threshold method, which is applicable to any infrared-illuminated eye images without a tuning parameter, is proposed for segmenting the pupil from the background images recorded by a low cost webcam placed near the eye. A convex hull and a dual-ellipse fitting method are also proposed to select pupil boundary points and to detect the eyelid occlusion state. Experimental results on a realistic video dataset show that the measurement accuracy using the proposed methods is higher than that of widely used manually tuned parameter methods or fixed parameter methods. Importantly, it demonstrates convenience and robustness for an accurate and fast estimate of eye activity in the presence of variations due to different users, task types, load, and environments. Cognitive load measurement in human-machine interaction can benefit from this computationally efficient implementation without requiring a threshold calibration beforehand. Thus, one can envisage a mini IR camera embedded in a lightweight glasses frame, like Google Glass, for convenient applications of real-time adaptive aiding and task management in the future.
Full Text Available Risks of eye damage and eyesight deterioration to a great extent depend on how efficient a biomechanical eye system is under energy-saving lighting conditions. The system's efficiency is determined by its adequacy in managing pupils and ciliary muscle. We analyzed mathematical models describing changes in pupil's diameter which were determined by light-technical parameters of illumination environment (luminance level and brightness. We highlighted the importance of ganglionic cells and the role they play in managing pupil's diameter (miosis when they are exposed to blue light within 480 nm spectrum. Basing on the assessment of a pupil's constriction under exposure to various light stimuli (blue, red, and green ones we worked out a melanopsin effect concept of a pupil's retention at miosis and showed that it could be a diagnostic sign of some diseases (age-related direct retinopathy, pancreatic diabetes under exposure to a blue light impulse with a certain wave length. Under exposure to blue light within 480 nm spectrum ganglionic cells form a managing signal for a sphincter muscle of a pupil and ciliary muscle which provides accommodation (as per Helmholtz and regulates aqueous humor flow in ciliary channel. All modern energy-saving light sources have a low energy level at wave length equal to 480 nm due to gap in their spectrum in comparison with sunlight spectrum with the same light temperature and luminance level. Inadequate management of pupil's diameter under artificial lighting conditions leads to melanopsin effect disorders and causes disharmony in managing aqueous humor outflow. All the above-stated factors under long-term visual load cause eye diseases risks in modern illumination environment. We detected that contemporary mathematic models describing pupil's diameter fluctuations needed to be refined allowing for new knowledge on functional peculiarities of retina cells and energy-saving light sources spectrum.

Purpose (1) To use finite element (FE) modelling to estimate local iris stresses (i.e. internal forces) as a result of mechanical pupil expansion; and to (2) compare such stresses as generated from several commercially available expanders (Iris hooks, APX dilator and Malyugin ring) to determine which design and deployment method are most likely to cause iris damage. Methods We used a biofidelic 3-part iris FE model that consisted of the stroma, sphincter and dilator muscles. Our FE model simulated expansion of the pupil from 3 mm to a maximum of 6 mm using the aforementioned pupil expanders, with uniform circular expansion used for baseline comparison. FE-derived stresses, resultant forces and area of final pupil opening were compared across devices for analysis. Results Our FE models demonstrated that the APX dilator generated the highest stresses on the sphincter muscles, (max: 6.446 MPa; average: 5.112 MPa), followed by the iris hooks (max: 5.680 MPa; average: 5.219 MPa), and the Malyugin ring (max: 2.144 MPa; average: 1.575 MPa). Uniform expansion generated the lowest stresses (max: 0.435MPa; average: 0.377 MPa). For pupil expansion, the APX dilator required the highest force (41.22 mN), followed by iris hooks (40.82 mN) and the Malyugin ring (18.56 mN). Conclusion Our study predicted that current pupil expanders exert significantly higher amount of stresses and forces than required during pupil expansion. Our work may serve as a guide for the development and design of next-generation pupil expanders. PMID:29538452

The attentional learning theory of Pearce and Hall () predicts more attention to uncertain cues that have caused a high prediction error in the past. We examined how the cue-elicited pupil dilation during associative learning was linked to such error-driven attentional processes. In three experiments, participants were trained to acquire associations between different cues and their appetitive (Experiment 1), motor (Experiment 2), or aversive (Experiment 3) outcomes. All experiments were designed to examine differences in the processing of continuously reinforced cues (consistently followed by the outcome) versus partially reinforced, uncertain cues (randomly followed by the outcome). We measured the pupil dilation elicited by the cues in anticipation of the outcome and analyzed how this conditioned pupil response changed over the course of learning. In all experiments, changes in pupil size complied with the same basic pattern: During early learning, consistently reinforced cues elicited greater pupil dilation than uncertain, randomly reinforced cues, but this effect gradually reversed to yield a greater pupil dilation for uncertain cues toward the end of learning. The pattern of data accords with the changes in prediction error and error-driven attention formalized by the Pearce-Hall theory. © 2017 The Authors.

Full Text Available The ability to predict when a person is about to fall asleep is an important challenge in recent biomedical research and has various possible applications. Sleepiness and fatigue are known to increase pupillary fluctuations and the occurrence of eye blinks. In this study, we evaluated the use of the pupil diameter to forecast sleep episodes of short duration (>1s. We conducted multi-channel physiological and pupillometric recordings (diameter, gaze position in 91 healthy volunteers at rest in supine position. Although they were instructed to keep their eyes open, short sleep episodes were detected in 20 participants (16 males, age: 26.2±5.6 years, 53 events in total. Before each sleep event, pupil size was extracted in a window of 30s (without additional sleep event. Mean pupil diameter and its standard deviation, Shannon entropy and wavelet entropy in the first half (15s were compared to the second half of the window (15s. Linear and nonlinear measures demonstrated an elevation of pupil size variability before sleep onset. Most obviously, WE and SD increased significantly from 0.054±0.056 and 0.38±0.16 mm to 0.113±0.103 (T(102=2.44, p<0.001 and 0.46±0.18 mm (T(104=3.67, p<0.05 in the second half of each analysis window. We were able to identify 83% of the pre-sleep segments by linear discriminant analysis. Although our data was acquired in an experimental condition, it suggests that pupillary unrest might be a suitable predictor of events related to transient sleep or inattentiveness. In the future, we are going to involve the other recorded physiological signals into the analysis.

Full Text Available Portrait painters are experts at examining faces and since emotional content may be expressed differently on each side of the face, consider that Rembrandt biased his male portraits to show their right cheek more often and female portraits to show their left cheek more often. This raises questions regarding the emotional significance of such biased positions. I presented rightward and leftward facing male and female portraits. I measured observers’ pupil size while asking observers to report how (displeasing they found each image. This was a methodological improvement over the type of research initially done by Eckhard Hess who claimed that pupils dilate to pleasant images and constrict to unpleasant images. His work was confounded since his images’ luminances and contrasts across conditions were inconsistent potentially affecting pupil size. To overcome this limitation I presented rightward or leftward facing male and female portraits by Rembrandt to observers in either their original or mirror-reversed position. I found that in viewing male portraits pupil diameter was a function of arousal. That is, larger pupil diameter occurred for images rated both low and high in pleasantness. This was not the case with female portraits. I discuss these findings in regard to the perceived dominance of males and how emotional expressions may be driven by hemispheric laterality.
Full Text Available While it has long been known that the pupil reacts to cognitive load, pupil size has received little attention in cognitive research because of its long latency and the difficulty of separating effects of cognitive load from the light reflex or effects due to eye movements. A novel measure, the Index of Cognitive Activity (ICA, relates cognitive effort to the frequency of small rapid dilations of the pupil. We report here on a total of seven experiments which test whether the ICA reliably indexes linguistically induced cognitive load: three experiments in reading (a manipulation of grammatical gender match/mismatch, an experiment of semantic fit, and an experiment comparing locally ambiguous subject versus object relative clauses, all in German, three dual-task experiments with simultaneous driving and spoken language comprehension (using the same manipulations as in the single-task reading experiments, and a visual world experiment comparing the processing of causal versus concessive discourse markers. These experiments are the first to investigate the effect and time course of the ICA in language processing. All of our experiments support the idea that the ICA indexes linguistic processing difficulty. The effects of our linguistic manipulations on the ICA are consistent for reading and auditory presentation. Furthermore, our experiments show that the ICA allows for usage within a multi-task paradigm. Its robustness with respect to eye movements means that it is a valid measure of processing difficulty for usage within the visual world paradigm, which will allow researchers to assess both visual attention and processing difficulty at the same time, using an eye-tracker. We argue that the ICA is indicative of activity in the locus caeruleus area of the brain stem, which has recently also been linked to P600 effects observed in psycholinguistic EEG experiments.

Retinal imaging with an adaptive optics (AO) system usually requires that the eye be centered and stable relative to the exit pupil of the system. Aberrations are then typically corrected inside a fixed circular pupil. This approach can be restrictive when imaging some subjects, since the pupil may not be round and maintaining a stable head position can be difficult. In this paper, we present an automatic algorithm that relaxes these constraints. An image quality metric is computed for each spot of the Shack-Hartmann image to detect the pupil and its boundary, and the control algorithm is applied only to regions within the subject's pupil. Images on a model eye as well as for five subjects were obtained to show that a system exit pupil larger than the subject's eye pupil could be used for AO retinal imaging without a reduction in image quality. This algorithm automates the task of selecting pupil size. It also may relax constraints on centering the subject's pupil and on the shape of the pupil.

An extensive design study was conducted to find the best optimal power distribution and stop location for a 7.5x afocal zoom lens that controls the pupil walk and pupil location through zoom. This afocal zoom lens is one of the three components in a VIS-SWIR high-resolution microscope for inspection of photonic chips. The microscope consists of an afocal zoom, a nine-element objective and a tube lens and has diffraction limited performance with zero vignetting. In this case, the required change in object (sample) size and resolution is achieved by the magnification change of the afocal component. This creates strict requirements for both the entrance and exit pupil locations of the afocal zoom to couple the two sides successfully. The first phase of the design study looked at conventional four group zoom lenses with positive groups in the front and back and the stop at a fixed location outside the lens but resulted in significant pupil walk. The second phase of the design study focused on several promising unconventional four-group power distribution designs with moving stops that minimized pupil walk and had an acceptable pupil location (as determined by the objective and tube lens).

Low-velocity mechanical impact and subsequent high explosive (HE) reaction are of concern in credible accident scenarios involving the handling, transport, and storage of nuclear weapons. Using modified Steven spigot gun tests, the authors have investigated the high-explosive violent-reaction (HEVR) potential of PBX 9501 to low-amplitude insult. Reliable modeling predictions require that one identify the relevant parameters and behavioral responses that are key to the reaction mechanism(s) in PBX 9501. Additional efforts have been targeted at identifying relevant differences in the response between baseline and stockpile-aged PBX 9501 to low-velocity impacts.

Full Text Available Background. The question of physical activity becomes more urgent every day. More and more parents think about the necessity of physical development of children at the same level as mental. So the studying of physical activity degree and its impact on mental capacity of today’s schoolchildren studied by different programs is becoming increasingly important. Objective of the work is to show the level of physical activity of pupils in middle school, studied by traditional and new programs. Materials and methods. The research included survey of the pupils of the school № 169 in the city of Kharkiv. The research involved three forms of pupils (three groups for parallel concurrent studies. All pupils aged 10–11 years studied by new and traditional programs. The pupils of forms 5E1 and 5E2 studied by a new program, the pupils of form 5P studies by traditional program. The pupils were surveyed in dynamics: in the beginning, middle and end of the school year and included the issues of physical and mental activity, personal care, and day regimen of pupils. The parents and children gave consent for taking part in the research. The data were by using the methods of variation statistics, correlation and variance analysis (SPSS-17 program. Results. It was identified the poor nighttime sleep duration, which was caused by various loads during the day. So the expansion of activities and duration of their time in these groups of pupils regardless of studying systems is due to the reduction of night sleep that can lead to its violation. The analysis of the physical activity of children’s groups revealed a low rate of morning exercises. It is interesting that the most restoration occurred in the groups of pupils who do sports (36.0 ± 9.6 % pupils of 5E1 form and 46.2 ± 9.8 pupils of 5P form to 75.0 ± 10.8 and 76.0 ± 8.5 pupils, respectively against 44.0 ± 9.9 % pupils of 5E2 form, among which only 21.4 ± 7.8 % of pupils did sports.

Inhomogeneous optical properties of biological samples make it difficult to obtain diffraction-limited resolution in depth. Correcting the sample-induced optical aberrations needs adaptive optics (AO). However, the direct wavefront-sensing approach commonly used in astronomy is not suitable for most biological samples due to their strong scattering of light. We developed an image-based AO approach that is insensitive to sample scattering. By comparing images of the sample taken with different segments of the pupil illuminated, local tilt in the wavefront is measured from image shift. The aberrated wavefront is then obtained either by measuring the local phase directly using interference or with phase reconstruction algorithms similar to those used in astronomical AO. We implemented this pupil-segmentation-based approach in a two-photon fluorescence microscope and demonstrated that diffraction-limited resolution can be recovered from nonbiological and biological samples.

Our purpose is to develop a computational approach that jointly assesses the impact of stimulus luminance and pupil size on visual quality. We compared traditional optical measures of image quality and those that incorporate the impact of retinal illuminance dependent neural contrast sensitivity. Visually weighted image quality was calculated for a presbyopic model eye with representative levels of chromatic and monochromatic aberrations as pupil diameter was varied from 7 to 1 mm, stimulus luminance varied from 2000 to 0.1 cd/m2, and defocus varied from 0 to -2 diopters. The model included the effects of quantal fluctuations on neural contrast sensitivity. We tested the model's predictions for five cycles per degree gratings by measuring contrast sensitivity at 5 cyc/deg. Unlike the traditional Strehl ratio and the visually weighted area under the modulation transfer function, the visual Strehl ratio derived from the optical transfer function was able to capture the combined impact of optics and quantal noise on visual quality. In a well-focused eye, provided retinal illuminance is held constant as pupil size varies, visual image quality scales approximately as the square root of illuminance because of quantum fluctuations, but optimum pupil size is essentially independent of retinal illuminance and quantum fluctuations. Conversely, when stimulus luminance is held constant (and therefore illuminance varies with pupil size), optimum pupil size increases as luminance decreases, thereby compensating partially for increased quantum fluctuations. However, in the presence of -1 and -2 diopters of defocus and at high photopic levels where Weber's law operates, optical aberrations and diffraction dominate image quality and pupil optimization. Similar behavior was observed in human observers viewing sinusoidal gratings. Optimum pupil size increases as stimulus luminance drops for the well-focused eye, and the benefits of small pupils for improving defocused image
Full Text Available It has been suggested that infants resonate emotionally to others' positive and negative affect displays, and that these responses become stronger towards emotions with negative valence around the age of 12-months. In this study we measured 6- and 12-month-old infants' changes in pupil diameter when presented with the image and sound of peers experiencing happiness, distress and an emotionally neutral state. For all participants the perception of another's distress triggered larger pupil diameters. Perceiving other's happiness also induced larger pupil diameters but for shorter time intervals. Importantly, we also found evidence for an asymmetry in autonomous arousal towards positive versus negative emotional displays. Larger pupil sizes for another's distress compared to another's happiness were recorded shortly after stimulus onset for the older infants, and in a later time window for the 6-month-olds. These findings suggest that arousal responses for negative as well as for positive emotions are present in the second half of the first postnatal year. Importantly, an asymmetry with stronger responses for negative emotions seems to be already present at this age.

Media have an influence on the human psyche similar to the addictive actions of psychoactive substances or gambling. Computer overuse is claimed to be a cause of psychiatric disturbances such as computer and Internet addiction. It has not yet been recognized as a disease, but it evokes increasing controversy and results in mental disorders commonly defined as computer and Internet addiction. This study was based on a diagnostic survey in which 120 subjects participated. The participants were pupils of three kinds of schools: primary, middle, and secondary school (high school). Information for this study was obtained from a questionnaire prepared by the authors as well as the State-Trait Anxiety Inventory (STAI) and the Psychological Inventory of Aggression Syndrome (IPSA-II). he results confirmed that every fourth pupil was addicted to the Internet. Internet addiction was very common among the youngest users of computers and the Internet, especially those who had no brothers and sisters or came from families with some kind of problems. Moreover, more frequent use of the computer and the Internet was connected with higher levels of aggression and anxiety. Because computer and Internet addiction already constitute a real danger, it is worth considering preventive activities to treat this phenomenon. It is also necessary to make the youth and their parents aware of the dangers of uncontrolled Internet use and pay attention to behavior connected with Internet addiction.

Regular consumption of a well balanced breakfast is a pre-requisite for normal growth and child development, along with the acquisition of proper eating habits. The family environment is crucial place where children learn such patterns of behaviour that form the basis for their development. To determine how family factors affect the regular eating of breakfast and types of foodstuffs consumed in primary school pupils, including food purchases made from vending machines and school tuck shops. Subjects were 836 pupils (435 girls and 401 boys, aged 6 - 13) from Warsaw and the surrounding areas. Appropriate socio-demographic data and relevant eating habits were obtained from direct interviewing of the subjects by means of a custom designed questionnaire. Statistical analyses were performed by the Kohonen type cluster analysis model and Chi-square test (Chi(2)); (p≤0.05). Three clusters of pupils were identified by their differing socio-demographics and eating habits (eg. rates of breakfast consumption, buying from vending machines or school tuck shops). The first and third clusters were mainly pupils from two-parent families with parents proportionally spending similar times at work, where respective breakfast (87% and 91%) and second breakfast (77% and 72%) consumption rates were also similar together with food shopping rates during school time (respectively 69% and 63%). Pupils with single-parents, multi-generation families or if both parents were profession- ally active, predominated in the second cluster. These ate breakfast (73%) and second breakfast (67%) more rarely, but more frequently shopped for food at school (84%). A small number of pupils had a packed second breakfast from home, rarely ate sandwiches, fruit and/or vegetables and dairy products but ate more sweets, sweet rolls and savoury snacks. However, a large number of subjects bought sandwiches, fresh fruit and/or vegetables and fast-food at school. Family factors were found to affect eating habits

When scanning faces, individuals with autism spectrum disorder (ASD) have shown reduced visual attention (e.g., less time on eyes) and atypical autonomic responses (e.g., heightened arousal). To understand how these differences might explain sub-clinical variability in social functioning, 9-month-olds, with or without a family history of ASD, viewed emotionally-expressive faces, and gaze and pupil diameter (a measure of autonomic activation) were recorded using eye-tracking. Infants at high-risk for ASD with no subsequent clinical diagnosis (HRA-) and low-risk controls (LRC) showed similar face scanning and attention to eyes and mouth. Attention was overall greater to eyes than mouth, but this varied as a function of the emotion presented. HRA- showed significantly larger pupil size than LRC. Correlations between scanning at 9 months, pupil size at 9 months, and 18-month social-communicative behavior, revealed positive associations between pupil size and attention to both face and eyes at 9 months in LRC, and a negative association between 9-month pupil size and 18-month social-communicative behavior in HRA-. The present findings point to heightened autonomic arousal in HRA-. Further, with greater arousal relating to worse social-communicative functioning at 18 months, this work points to a mechanism by which unaffected siblings might develop atypical social behavior.
Full Text Available This study investigates holistic craft processes in craft education with an instrument for data-collection and self-assessment. Teaching in a study context is based on co-teaching and a design process, highlighted by the Finnish Basic Education Core Curriculum 2014. The school architecture and web-based learning environment is combined. Division for textiles and technical work is no longer supported in this multimaterial learning environment. The aim of the study is to 1 make pupils’ holistic craft processes visible in everyday classroom practices with information collected by a mobile-application and 2 point out the curriculum topics that are covered during everyday classroom practices as defined by the teachers. The data is collected using an Experience Sampling Method with a gamified learning analytics instrument. Teachers’ classroom activities were used as the backbone for the thematic mapping of the craft curriculum. Preliminary measurements were carried out in a Finnish primary school in grades 5–6 (age 10–12, n = 125 during a four-week period in October-November 2016. The list of classroom activities was updated after the four weeks’ experiment and was tested in March-May 2017 with all the pupils of the pilot school (N = 353. The key findings were that a for pupils the self-assessment was easy as a technical process but there were several factors in the everyday classroom settings that made the process challenging and b it was relatively difficult for teachers to describe the classroom activities in terms of the new curriculum; however, after four weeks they could not only described the activities in more details but had also developed new activities that supported the ideas of the new curriculum better.Keywords: multi-material craft, learning environment, holistic craft process, experience sampling method

We have developed a catalytic allylic amination involving tertiary aminoesters and allylcarbonates, which is the first example of the use of tertiary amines as intermolecular nucleophiles in metal-catalyzed allylic substitution chemistry. This process is employed in a tandem ammonium ylide generation/[2,3]-rearrangement reaction, which formally represents a palladium-catalyzed Stevens rearrangement. Low catalyst loadings and mild reaction conditions are compatible with an unprecedented substrate scope for the ammonium ylide functionality, and products are generated in high yields and diastereoselectivities. Mechanistic studies suggested the reversible formation of an ammonium intermediate.

Presbyopia correction involves different types of studies such as lens design, clinical study, and the development of objective metrics, such as the visual Strehl ratio. Different contact lens designs have been proposed for presbyopia correction, but performance depends on pupil diameter. We will analyze the potential use of a nonsymmetrical element, a cubic phase mask (CPM) solution, to develop a contact or intraocular lens whose performance is nearly insensitive to changes in pupil diameter. We will show the through focus optical transfer function of the proposed element for different pupil diameters ranging from 3 to 7 mm. Additionally, we will show the images obtained through computation and experiment for a group of eye charts with different visual acuities. Our results show that a CPM shaped as 7.07 μm*(Z33-Z3-3)-0.9 μm Z20 is a good solution for a range of clear vision with a visual acuity of at least 0.1 logMar from 0.4 to 6 m for pupil diameters in the 3- to 7-mm range. Our results appear to be a good starting point for further development and study of this kind of CPM solution for presbyopia.
The aim of the study was to investigate factors affecting condom use among senior secondary school pupils in South Africa. Objectives were to identify the sociodemographic characteristics and sexual history, knowledge about correct condom use, source of condom information, AIDS health beliefs, self efficacy of condom use, correlates and predictors of condom use in Grade 12 students. Cross sectional survey. 460 Grade 12 secondary school pupils from three rural schools. The sample included 460 Grade 12 secondary school pupils, 170 (37%) males and 290 (63%) females in the age range of 16 to 30 years (mean age 19.7 yrs, SD = 2.5). Self reported sexual activity and condom use (12 items); source of 'condom' information (12 items); knowledge of correct condom use (10 items); a 16 item AIDS Health Belief Scale and a 28 item Condom Use Self-Efficacy Scale. About half of those sexually active (52.6% males and 40.5% females) reported never having used condoms. About 90% levels of correct answers on condom knowledge were found for the items of "protection against AIDS" and "expire date of condoms". Knowing someone with HIV/AIDS was related to current condom use and a history of STD with lifetime condom use. The four AIDS beliefs sub-scales were all related to self efficacy of condom use. Behavioural norm to use condoms, attitudes towards condom use, normative beliefs to use of condoms and subjective norm to use condoms were all related to condom use intention. Normative beliefs and subjective norms to use condoms were both negatively related with lifetime condom use, current condom use, and self efficacy in condom use. Normative beliefs, attitudes and subjective norms about condoms predicted condom use intention, AIDS susceptibility and AIDS benefits predicted condom use with last sexual partner, and AIDS benefits and AIDS barriers predicted condom use intention. Findings have relevant implications and are discussed in the context of developing an educational or intervention

A major task involved in teaching pupils is to group them wisely for instruction. Most elementary schools group learners in terms of a self-contained classroom. While it may seem extreme, all curriculum areas on each grade in the elementary school may be departmentalized. In some ways, departmentalization harmonizes more with a separate subjects…
Full Text Available Didactic potential of upbringing pupils in educational institutions of the Diaspora by means of artistic word has been analyzed. The attention is paid to the function of art – Ukrainian literature, which promotes the formation of fully developed personality, their preparation for the conscious and active labour activity, and therefore upbringing is closely connected with life. It is cleared out that when plunging into the system of the artistic world, the pupil learns from the life of the main positive characters how to live in the society and to be useful, because textbooks and manuals on the native literature, readers in the Diaspora provide the basis for children to learn the behaviour of consciousness, and the latter, as it is known, depends on the construction of the world in themselves, that is called the worldview. It is proved that the powerful moral-educational and artistic-aesthetic potential of Ukrainian literature is being implemented in the books of Western Ukrainian Diaspora with the aim of ethnic and cultural enrichment of pupils and above all the formation of national consciousness of Ukrainian children, active choice of their values of national spirituality. It is established that the didactic potential of the upbringing of pupils by means of artistic word allows instilling love to the native language, to Ukraine, and thus it slows down the process of assimilation. On the basis of the study of the scientific-pedagogical heritage of emigration teachers-philologists, the theoretical approaches and practice of schoolchildren education by means of the word have been analyzed, the significance of their experience for the modern educational practice has been substantiated. The system of education of schoolchildren by means of the word, which has been developed over the years, is actual for the development of pedagogical science and practice.

Norwich's Entropy Theory of Perception (1975-present) is a general theory of perception, based on Shannon's Information Theory. Among many bold claims, the Entropy Theory presents a truly astounding result: that Stevens' Law with an Index of 1, an empirical power relation of direct proportionality between perceived taste intensity and stimulus concentration, arises from theory alone. Norwich's theorizing starts with several extraordinary hypotheses. First, 'multiple, parallel receptor-neuron units' without collaterals 'carry essentially the same message to the brain', i.e. the rate-level curves are identical. Second, sensation is proportional to firing rate. Third, firing rate is proportional to the taste receptor's 'resolvable uncertainty'. Fourth, the 'resolvable uncertainty' is obtained from Shannon's Information Theory. Finally, 'resolvable uncertainty' also depends upon the microscopic thermodynamic density fluctuation of the tasted solute. Norwich proves that density fluctuation is density variance, which is proportional to solute concentration, all based on the theory of fluctuations in fluid composition from Tolman's classic physics text, 'The Principles of Statistical Mechanics'. Altogether, according to Norwich, perceived taste intensity is theoretically proportional to solute concentration. Such a universal rule for taste, one that is independent of solute identity, personal physiological differences, and psychophysical task, is truly remarkable and is well-deserving of scrutiny. Norwich's crucial step was the derivation of density variance. That step was meticulously reconstructed here. It transpires that the appropriate fluctuation is Tolman's mean-square fractional density fluctuation, not density variance as used by Norwich. Tolman's algebra yields a 'Stevens Index' of -1 rather than 1. As 'Stevens Index' empirically always exceeds zero, the Index of -1 suggests that it is risky to infer psychophysical laws of sensory response from information theory

To determine the causes of childhood blindness and severe visual impairment in pupils attending schools for the blind in Burundi in order to assist planning for services in the country. All pupils attending three schools for the blind in Burundi were examined. A modified WHO/PBL eye examination record form for children with blindness and low vision was used to record the findings. Data was analyzed for those who became blind or severely visually impaired before the age of 16 years. Overall, 117 pupils who became visually impaired before 16 years of age were examined. Of these, 109 (93.2%) were blind or severely visually impaired. The major anatomical cause of blindness or severe visual impairment was cornea pathology/phthisis (23.9%), followed by lens pathology (18.3%), uveal lesions (14.7%) and optic nerve lesions (11.9%). In the majority of pupils with blindness or severe visual impairment, the underlying etiology of visual loss was unknown (74.3%). More than half of the pupils with lens related blindness had not had surgery; among those who had surgery, outcomes were generally poor. The causes identified indicate the importance of continuing preventive public health strategies, as well as the development of specialist pediatric ophthalmic services in the management of childhood blindness in Burundi. The geographic distribution of pupils at the schools for the blind indicates a need for community-based programs to identify and refer children in need of services.

Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening drug reactions involving skin and membranes mucous, which are associated with significant morbidity and mortality and triggered, especially by drug exposure. Different studies have demonstrated that drug response is a multifactorial character and that the interindividual variability in this response depends on both environmental and genetic factors. The last ones have a relevant significance. In fact, the identification of new specific genetic markers involved in the response to drugs, will be of great utility to establish a more personalized therapeutic approach and to prevent the appearance of these adverse reactions. In this review, we summarize recent progresses in the Pharmacogenetics studies related to Stevens-Johnson syndrome/toxic epidermal necrolysis reporting the major genetic factors identified in the last years as associated with the disease and highlighting the use of some of these genomic variants in the clinical practice.

Ocular aberration correction can significantly improve visual function of the human eye. However, even under ideal aberration correction conditions, pupil diffraction restricts the resolution of retinal images. Pupil filtering is a simple super-resolution (SR) method that can overcome this diffraction barrier. In this study, a 145-element piezoelectric deformable mirror was used as a pupil phase filter because of its programmability and high fitting accuracy. Continuous phase-only filters were designed based on Zernike polynomial series and fitted through closed-loop adaptive optics. SR results were validated using double-pass point spread function images. Contrast sensitivity was further assessed to verify the SR effect on visual function. An F-test was conducted for nested models to statistically compare different CSFs. These results indicated CSFs for the proposed SR filter were significantly higher than the diffraction correction (p vision optical correction of the human eye.

The rising incidence of drug abuse among youths in Nigeria is a source of concern for health educators. This study was carried out on primary six pupils to determine the effect of a Multiple Intelligences Teaching Approach Drug Education Programme (MITA-DEP) on pupils' acquisition of drug refusal skills. A programme of drug education based on the Multiple Intelligences Teaching Approach (MITA) was developed. An experimental group was taught using this programme while a control group was taught using the same programme but developed based on the Traditional Teaching Approach. Pupils taught with the MITA acquired more drug refusal skills than those taught with the Traditional Teaching Approach. Urban pupils taught with the MITA acquired more skills than rural pupils. There was no statistically significant difference in the mean refusal skills of male and female pupils taught with the MITA. © The Author(s) 2014.

To investigate the relationship between neuron density of the superior cervical sympathetic ganglia and pupil diameter in subarachnoid hemorrhage. This study was conducted on 22 rabbits; 5 for the baseline control group, 5 for the SHAM group and 12 for the study group. Pupil diameters were measured via sunlight and ocular tomography on day 1 as the control values. Pupil diameters were re-measured after injecting 0.5 cc saline to the SHAM group, and autologous arterial blood into the cisterna magna of the study group. After 3 weeks, the brain, superior cervical sympathetic ganglia and ciliary ganglia were extracted with peripheral tissues bilaterally and examined histopathologically. Pupil diameters were compared with neuron densities of the sympathetic ganglia and ciliary ganglia which were examined using stereological methods. Baseline values were; normal pupil diameter 7.180±620 ?m and mean neuron density of the superior cervical sympathetic ganglia 6.321±510/mm3, degenerated neuron density of ciliary ganglia was 5±2/mm3 after histopathological examination in the control group. These values were measured as 6.850±578 ?m, 5.950±340/mm3 and 123±39/mm3 in the SHAM group and 9.910±840 ?m, 7.950±764/mm3 and 650±98/mm3 in the study group. A linear relationship was determined between neuron density of the superior cervical sympathetic ganglia and pupil diameters (p < 0.005). Degenerated ciliary ganglia neuron density had an inverse effect on pupil diameters in all groups (p < 0.0001). Highly degenerated neuron density of the ciliary ganglion is not responsible for pupil dilatation owing to parasympathetic pupilloconstrictor palsy, but high neuron density of the pupillodilatatory superior cervical sympathetic ganglia should be considered an important factor for pupil dilatation.

In this study, we investigate the effects of decision-related factors on recognition memory in pupil old/new paradigms. In Experiment 1, we used an old/new paradigm with words and pseudowords and participants made lexical decisions during recognition rather than old/new decisions. Importantly, participants were instructed to focus on the nonword-likeness of presented items, not their word-likeness. We obtained no old/new effects. In Experiment 2, participants discriminated old from new words and old from new pseudowords during recognition, and they did so as quickly as possible. We found old/new effects for both words and pseudowords. In Experiment 3, we used materials and an old/new design known to elicit a large number of incorrect responses. For false alarms ("old" response for new word), we found larger pupils than for correctly classified new items, starting at the point at which response execution was allowed (2750ms post stimulus onset). In contrast, pupil size for misses ("new" response for old word) was statistically indistinguishable from pupil size in correct rejections. Taken together, our data suggest that pupil old/new effects result more from the intentional use of memory than from its automatic use. Copyright © 2017 Elsevier Ltd. All rights reserved.
Ways of Narrating Memory: Hannah Arendt’s "Eichmann in Jerusalem" and Steven Spielberg’s "Schindler’s List" / Formas de narração da memória: “Eichmann em Israel”, de Hannah Arendt e “A Lista de Schindler”, de Steven Spielberg
Full Text Available Abstract It is self-evident that events of the past are bound to places and acting people, they are playing a decisive role for memory and history. Meaning and importance of places and actions in the past depend on their contexts and each change inevitably also changes the meaning of the events itself. I would like to demonstrate some of the consequences of such a change by comparing Hannah Arendt’s “Eichmann in Jerusalem“ with Steven Spielberg’s “Schindler’s List“ who decontextualized a factual story and thus changed places and acting people. But before doing this, I would like to emphasize the importance which places and acting people play for memory and history with some perhaps unusual remarks. They refer to the official European history and politics which seem to be marked by the absence of places and acting people.Keywords: Eichmann in Jerusalem, Hannah Arendt, Schindler’s List, Steven SpielbergResumo É autoevidente que acontecimentos do passado estão condicionados a lugares e a pessoas atuantes, que têm papel fundamental na memória e na história. O significado e a importância de lugares e de ações do passado dependem de seu contexto e cada mudança sua inevitavelmente altera também os próprios acontecimentos. Eu gostaria de demonstrar algumas das consequências de tal mudança comparando “Eichmann em Israel”, de Hannah Arendt com “A Lista de Schindler”, de Steven Spielberg, que descontextualizou uma história real e, assim, modificou lugares e pessoas de atuação. Mas antes disso, eu gostaria de enfatizar a importância que lugares e pessoas atuantes têm a memória e na história com alguns comentários talvez inusitados. Eles fazem referência à História oficial e à política da Europa que parecem ser marcados pela ausência de lugares e de pessoas de atuação marcante.Palavras-chaves: Eichmann em Israel, Hannah Arendt, Lista de Schindler, Steven Spielberg
Full Text Available Stevens-Johnson syndrome (SJS is an uncommon occurrence in Mycoplasma pneumoniae (M. pneumoniae infection (1–5% and has been mainly reported in children and young adults. We present a case of SJS in a 32-year-old male induced by M. pneumoniae infection. This patient presented with fever, cough, and massive occupation of mucus membranes with swelling, erythema, and necrosis accompanied by a generalized cutaneous rash. He clinically responded after treatment with antibiotics and IVIG. SJS is usually a drug-induced condition; however, M. pneumoniae is the commonest infectious cause and should be considered in the differential diagnosis.

Full Text Available Four-month-old infants were presented with feeding actions performed in a rational or irrational manner. Infants reacted to the irrational feeding actions by dilating their pupils, but only in the presence of rich contextual constraints. The study demonstrates that teleological processes are online at 4 months of age and illustrates the usefulness of pupil dilations as a measure of social cognitive processes early in infancy.

Discusses how the teacher can deal with difficulties pupils of varying ages have in understanding certain chemical ideas. The article does not support using a Piagetian model for science courses in secondary schools. It suggests that Ausubel's learning theory is of much more use to the practicing teacher. (HM)
Full Text Available An 11-year-old boy presented with a total retinal detachment in his right eye. He had a bilateral 360° argon laser treatment for an active retinopathy of prematurity performed after his birth. He underwent an uneventful pars plana vitrectomy, encircling band, 810-nm diode endolaser and heavy silicone oil (Densiron® endotamponade. A tonic pupil and abolition of corneal sensitivity, with a large epithelial defect, were observed during the postoperative period. We discuss the possible etiopathogenic mechanisms of the long and short ciliary nerves damage, and the role that retinopathy of prematurity and retinal detachment laser treatment and the encircling band placement might have played in the development of the tonic pupil and the corneal anesthesia.

To evaluate and describe the pupil ruff changes and relationship to intraocular pressure, pseudoexfoliation syndrome and glaucoma status in an optometric population in New Zealand. Prospective cross-sectional survey of an optometric population. Six hundred and twenty subjects over 50 years old routinely attending the participating optometry practices. Exclusion criteria included previous intraocular surgery, ophthalmic laser, uveitis, angle closure and secondary glaucoma. Multicentre study involving 11 optometry practices in the Wellington region, New Zealand. The pupillary ruff and associated gonioscopy findings of study participants were graded based on the previously published Pupil Ruff Atrophy grading system. Parameters evaluated include pupillary ruff absence and abnormality, pseudoexfoliation material and trabecular meshwork pigmentation. Correlations between intereye Pupil Ruff Atrophy grading differences and inter-eye intraocular pressure and cup:disc ratio differences. Six hundred and twenty subjects were included, with a mean age of 62.2 ± 9.1 years and mean intraocular pressure of 14.8 ± 3.4 mmHg. Four hundred and fourteen (66.8%) had bilateral pupil ruff changes and 12 (1.5%) had pseudoexfoliation. Inter-eye intraocular pressure asymmetry was significantly correlated with amount of missing pupillary ruff (r = 0.111; P = 0.022) and trabecular meshwork pigmentation (r = 0.147; P = 0.002). Inter-eye cup:disc ratio asymmetry was not correlated with any of the Pupil Ruff Atrophy grading parameters. Asymmetry of pupillary ruff absence and trabecular meshwork pigmentation was correlated with intraocular pressure asymmetry (but not with cup:disc ratio asymmetry) in a general optometric population setting in New Zealand. © 2012 The Authors.

Full Text Available Factors interrelating with interest in physics learning are gender, perceived relevance, contents and contexts of physics, and teaching methods. Finnish ninth grade secondary school pupil interest in physics in different contexts was investigated with a survey conducted in connection with the international ROSE project. The sample consisted of 3626 pupils (median age 15 in 61 schools. Means of all items that belong to school physics context for both girls and boys were under the middle of the scale. The most interesting things (especially for girls were connected with human being and the less interesting (especially for girls were connected in artefacts and technological processes. Astronomical context was rather interesting for both genders. The main message of the study is that interesting new curricular approaches and textbooks can be developed by combining technological and human or astronomical contexts.

To determine working distance, pupil diameter and illumination in real life conditions in a sample of presbyopic participants performing habitual tasks. A total of 59 presbyopic subjects (aged between 45 and 63 years) with different occupational backgrounds participated in the study. Participants were first interviewed regarding their habitual tasks with the aid of an ad hoc questionnaire, following which in-office photopic and mesopic pupil diameter was determined. Pupil diameter was also evaluated while participants conducted each of the self-reported habitual tasks by taking a photograph, which was later submitted to image analysis. In addition, working distance was determined with a measuring tape and the illumination that reached the pupil during each of the different tasks was measured, in lux, with a light meter. The four most common habitual tasks were computer use, reading, sewing and sports. A high intersubject variability was found in pupil diameter, working distance and illumination conditions while conducting the same task. Statistically significant differences were found between the in-office measured photopic and mesopic pupil diameters and those obtained while participants were conducting their habitual tasks in real life conditions (all p<0.001). Potential multifocal contact lens users may present with different ages, different jobs or hobbies and different preferences regarding lighting conditions and working distances. This results in different pupil size, even within the same task. This information may be critical when selecting a particular lens design and add power. Eye care practitioners are therefore advised to assess pupil diameter in real life conditions. Copyright © 2015 Spanish General Council of Optometry. Published by Elsevier Espana.

The ability to adaptively shift between exploration and exploitation control states is critical for optimizing behavioral performance. Converging evidence from primate electrophysiology and computational neural modeling has suggested that this ability may be mediated by the broad norepinephrine projections emanating from the locus coeruleus (LC) [Aston-Jones, G., & Cohen, J. D. An integrative theory of locus coeruleus-norepinephrine function: Adaptive gain and optimal performance. Annual Review of Neuroscience, 28, 403-450, 2005]. There is also evidence that pupil diameter covaries systematically with LC activity. Although imperfect and indirect, this link makes pupillometry a useful tool for studying the locus coeruleus norepinephrine system in humans and in high-level tasks. Here, we present a novel paradigm that examines how the pupillary response during exploration and exploitation covaries with individual differences in fluid intelligence during analogical reasoning on Raven's Advanced Progressive Matrices. Pupillometry was used as a noninvasive proxy for LC activity, and concurrent think-aloud verbal protocols were used to identify exploratory and exploitative solution periods. This novel combination of pupillometry and verbal protocols from 40 participants revealed a decrease in pupil diameter during exploitation and an increase during exploration. The temporal dynamics of the pupillary response was characterized by a steep increase during the transition to exploratory periods, sustained dilation for many seconds afterward, and followed by gradual return to baseline. Moreover, the individual differences in the relative magnitude of pupillary dilation accounted for 16% of the variance in Advanced Progressive Matrices scores. Assuming that pupil diameter is a valid index of LC activity, these results establish promising preliminary connections between the literature on locus coeruleus norepinephrine-mediated cognitive control and the literature on analogical

To promote awareness of animal experimentation ethics among teenagers, we created an educational pamphlet and an accompanying questionnaire. One hundred Indian teenage school pupils were given the pamphlet and subsequently surveyed with the questionnaire, to evaluate: a) their perception of animal experimentation ethics; and b) their opinion on the effectiveness of the pamphlet, according to gender and school grade/age. There was a significant correlation between grade/age and support for animal experimentation, i.e. senior students were more inclined to show support for animal experimentation. There was also a significant correlation between gender and perception of the need to learn about animal experimentation ethics, with girls more likely to feel the need to learn about ethics than boys. In addition, the four questions relating to the usefulness of the pamphlet, and student satisfaction with its content, received positive responses from the majority of the students. Even though the pamphlet was concise, it was apparent that three quarters of the students were satisfied with its content. Gender and age did not influence this level of satisfaction. Overall, our study shows that there is a significant correlation between a pupil`s school grade/age and their support for animal experimentation, and that there is also a significant correlation between gender and the perceived need to learn about animal experimentation ethics. This pilot scheme involving an educational pamphlet and questionnaire could be beneficial in helping to formulate basic strategies for educating teenage school pupils about animal ethics. 2017 FRAME.

Obese students used to eat faster (p<0.05. Conclusion: In conclusion, high intakes of energy, protein, carbohydrate, tomato chips and puff and high eating speed were associated to obesity in Ahwaz primary school pupils.
Full Text Available Pupil dilation is implicated as a marker of decision-making as well as of cognitive and emotional processes. Here we tested whether individuals can exploit another's pupil to their advantage. We first recorded the eyes of 3 "opponents", while they were playing a modified version of the "rock-paper-scissors" childhood game. The recorded videos served as stimuli to a second set of participants. These "players" played rock-paper-scissors against the pre-recorded opponents in a variety of conditions. When players just observed the opponents' eyes without specific instruction their probability of winning was at chance. When informed that the time of maximum pupil dilation was indicative of the opponents' choice, however, players raised their winning probability significantly above chance. When just watching the reconstructed area of the pupil against a gray background, players achieved similar performance, showing that players indeed exploited the pupil, rather than other facial cues. Since maximum pupil dilation was correct about the opponents' decision only in 60% of trials (chance 33%, we finally tested whether increasing this validity to 100% would allow spontaneous learning. Indeed, when players were given no information, but the pupil was informative about the opponent's response in all trials, players performed significantly above chance on average and half (5/10 reached significance at an individual level. Together these results suggest that people can in principle use the pupil to detect cognitive decisions in another individual, but that most people have neither explicit knowledge of the pupil's utility nor have they learnt to use it despite a lifetime of exposure.

Erythema multiforme (EM) and Stevens-Johnson syndrome (SJS) are thought to be hypersensitivity syndromes with various causes, and radiotherapy might be one of the causes of these syndromes. We herein report two cases of EM/SJS following radiotherapy. The first case was a 63-year-old woman with breast cancer. At the end of postoperative radiotherapy with 60 Gy, severe pruritic erythema appeared in the irradiated area and spread over the whole body. She was diagnosed with EM by a skin biopsy. The second case was a 77-year-old woman with uterine cervical cancer who underwent postoperative radiotherapy. At a dose of 30.6 Gy, pruritic redness appeared in the irradiated area and the precordial region, and it became widespread rapidly with polymorphic transformation. Although without any histological confirmation, SJS was strongly suspected because of her pruritic conjunctivitis. Because both patients were given medicines during irradiation, radiotherapy may not be the only cause of EM/SJS. However, it should be noted that radiotherapy might trigger EM/SJS. (author)

The objective was to observe and document food behaviours of secondary school pupils from schools in a London borough. The research design combined a number of methods which included geographic information system (GIS) mapping of food outlets around three schools, systemised observations of food purchasing in those outlets before, during and after school, and focus groups conducted with pupils of those schools to gather their views in respect to those food choices. Results are summarised under the five 'A's of Access, Availability, Affordability and Acceptability & Attitudes: Access in that there were concentrations of food outlets around the schools. The majority of pupil food purchases were from newsagents, small local shops and supermarkets of chocolate, crisps (potato chips), fizzy drinks and energy drinks. Availability of fast food and unhealthy options were a feature of the streets surrounding the schools, with 200 m the optimal distance pupils were prepared to walk from and back to school at lunchtime. Affordability was ensured by the use of a consumer mentality and pupils sought out value for money offers; group purchasing of 'two for one' type offers encouraged this trend. Pupils reported healthy items on sale in school as expensive, and also that food was often sold in smaller portion sizes than that available from external food outlets. Acceptability and Attitudes, in that school food was not seen as 'cool', queuing for school food was not acceptable but queuing for food from takeaways was not viewed negatively; for younger pupils energy drinks were 'cool'. In conclusion, pupils recognised that school food was healthier but provided several reasons for not eating in school related to the five 'A's above. Copyright © 2016 Elsevier Ltd.

A gaze shift from a target at distance to a target at near leads to pupillary constriction. The regulation of this pupillary near response is ill known. We investigated the impact of accommodation, convergence, and proximity on the pupillary diameter. We recorded pupil size and vergence eye movements with the use of an infrared eye tracker. We determined the pupillary response in four conditions: (1) after a gaze shift from far to near without accommodation, (2) after a gaze shift from far to near with neither accommodation nor convergence, (3) after accommodation alone, and (4) after accommodation with convergence without a gaze shift to near. These responses were compared to the pupil response of a full near response and to a gaze shift from one far target to another. We found a reliable pupillary near response. The removal of both accommodation and convergence in gaze shift from far to near abolished the pupillary near response. Accommodation alone did not induce pupillary constriction, while convergence and accommodation together induced a pupil response similar to the full near response. The main trigger for the pupillary response seems to be convergence. Neither accommodation nor proximity alone induce a significant pupillary constriction. This suggests that the miosis of the near triad is closely coupled to the vergence system rather than being independently regulated.

Result: tendency of deterioration of pupils health during training in middle classes is proved; obtained data in accordance with the typology compiled reflect the awareness of some students health as a means of raising the status, as well as the failure to understand half the researched values of physical education in maintaining health and disinterest in physical education. Conclusion: problems of school physical education are determined by the low level of the culture of health of the entire Ukrainian society.
Full Text Available Attention capacities, alerting responses, orienting to sensory stimulation, and executive monitoring of performance are considered independent yet interrelated systems. These operations play integral roles in regulating the behavior of diverse species along the evolutionary ladder. Each of the primary attention constructs—alerting, orienting, and executive monitoring— involves salient autonomic correlates as evidenced by changes in reactive pupil dilation (PD, heart rate, and skin conductance. Recent technological advances that use remote high-resolution recording may allow the discernment of temporo-spatial attributes of autonomic responses that characterize the alerting, orienting, and executive monitoring networks during free viewing, irrespective of voluntary performance. This may deepen the understanding of the roles of autonomic regulation in these mental operations and may deepen our understanding of behavioral changes in verbal as well as in non-verbal species.The aim of this study was to explore differences between psychosensory pupil dilation responses in alerting, orienting, and executive conflict monitoring tasks to generate estimates of concurrent locus coeruleus (LC noradrenergic input trajectories in healthy human adults using the attention networks test (ANT. The analysis revealed a construct-specific pattern of pupil responses: alerting is characterized by an early component (Pa, its acceleration enables covert orienting, and executive control is evidenced by a prominent late component (Pe. Pupil dilation characteristics seem to be task-sensitive, allowing exploration of mental operations irrespective of conscious voluntary responses. These data may facilitate development of studies designed to assess mental operations in diverse species using autonomic responses.
Full Text Available Perceptual learning refers to the improvement of perceptual sensitivity and performance with training. In this study, we examined whether learning is accompanied by a release from mental effort on the task, leading to automatization of the learned task. For this purpose, we had subjects conduct a visual search for a target, defined by a combination of orientation and spatial frequency, while we monitored their pupil size. It is well known that pupil size reflects the strength of mental effort invested in a task. We found that pupil size increased rapidly as the learning proceeded in the early phase of training and decreased at the later phase to a level half of its maximum value. This result does not support the simple automatization hypothesis. Instead, it suggests that the mental effort and behavioral performance reflect different aspects of perceptual learning. Further, mental effort would be continued to be invested to maintain good performance at a later stage of training.

The use of phenytoin as a prophylactic anticonvulsant after brain surgery, particularly for brain tumors, is a common practice, regardless of whether the patient has a previous history of convulsions. This treatment policy assumes that the benefits exceed the risks. Four cases are described of adverse reactions of phenytoin during the cocomitant use of cranial radiotherapy. In one patient this proved fatal. There is increasing anecdotal support in the literature for a synergistic effect between phenytoin therapy and cranial radiotherapy that can result in the life-threatening Stevens-Johnson syndrome. While the association is uncommon, four cases within 24 months in one department suggest that the routine use of postoperative phenytoin as a prophylactic anticonvulsant in the absence of a history of seizures may not be warranted, particularly if the patient is to receive cranial radiotherapy.

Full Text Available Photosynthesis is the most important biochemical process on Earth. Most living beings depend on it directly or indirectly. Knowledge about photosynthesis enables us to understand how the world functions as an ecosystem and how photosynthesis acts as a bridge between the non-living and living worlds. It is, therefore, understandable that photosynthesis is included in national curricula around the world. The practice unfortunately shows that students at all school levels mostly learn about photosynthesis by rote. Consequently, they have difficulties understanding this vital process. Research also shows many misconceptions in relation to photosynthesis among students of different ages. Based on these, the main aim of our study was to explore the scientific conceptions about photosynthesis held by primary school pupils and student teachers of biology. Data were collected using a questionnaire containing seven biology content questions. The sample consisted of 634 participants, 427 primary school pupils (aged 11–14, and 207 student teachers of biology (aged 20–23. We found that the populations of primary school pupils and student teachers of biology differ greatly concerning scientific conceptions of photosynthesis. The student teachers showed good and complex understanding of photosynthesis, while pupils showed some misconceptions (location of chlorophyll and photosynthesis in a plant, transformation of energy in photosynthesis. Analysis of the development of scientific conceptions about photosynthesis with age showed that there is very little progress among primary school pupils and none among biology student teachers. More involvement of student teachers of biology in practical work at primary schools during their study was suggested to make student teachers aware of, and better understand pupils’ misconceptions.

Full Text Available Topical and/or intracameral administration of anticholinergic and/or sympathomimetic mydriatic agents which are usually used for pupillary dilation during cataract surgery, have some disadvantages such as slow onset of dilation and adverse ocular and systemic effects. We evaluated intracameral injection of preservative-free 1% lidocaine without using any preoperative or intraoperative mydriatics to induce pupil dilation in 31 consecutive eyes scheduled for phacoemulsification cataract extraction and intraocular lens implantation. Pupil diameter was measured before and 90 sec after intracameral lidocaine injection. After intracameral lidocaine injection, the mean pupil diameter was significantly greater than the baseline measurement (P< 0.001. No additional mydriatics were needed up to the end of the operations. Intracameral preservative-free lidocaine 1% has a rapid and effective mydriasis that could be a safe alternative to topical and intracameral mydriatics in phacoemulsification.

Imaging the retina at high resolution has numerous potential medical applications, and yet for the development of commercial products that can be used in the clinic, the complexity and high cost of the present research systems have to be addressed. We present a new method to control the deformable mirror in real time based on pupil tracking measurements which uses the default camera for the alignment of the eye in the retinal imaging system and requires no extra cost or hardware. We also present the first experiments done with a compact adaptive optics flood illumination fundus camera where it was possible to compensate for the higher order aberrations of a moving model eye and in vivo in real time based on pupil tracking measurements, without the real time contribution of a wavefront sensor. As an outcome of this research, we showed that pupil tracking can be effectively used as a low cost and practical adaptive optics tool for high resolution retinal imaging because eye movements constitute an important part of the ocular wavefront dynamics.
Full Text Available Background:Olanzapine is a highly tolerable and easily affordable atypical antipsychotic drug which has been commonly prescribed in both inpatient and outpatient settings for several mental disorders. Olanzapine overdose is commonly seen in psychiatric patients, who attempt suicide by intoxicating themselves with their own prescribed medications. Increased olanzapine use is associated with increased incidence of overdosing. Case Presentation:We are reporting a case of olanzapine overdosage as a cause of pinpoint pupils and altered sensorium with exclusion of other differentials. The mainstay of managementof olanzapine overdose is general supportive and symptomatic measures. Discussion: Pinpoint pupils with altered sensorium and agitation are always an alarming situation for a clinician, because of differentials like organophosphorus poisoning, pontine hemorrhage and opium overdosing. Due to olanzapine overdosage, similar clinical picture can be confusing in the emergency department and early identification of such cases is helpful to decrease the risk of fatality. Conclusion: This case highlights the significance of olanzapine overdosing as a differential diagnosis for patients presented with altered sensorium and pinpoint pupils in the emergency department. Olanzapine overdosage is associated with high morbidity and mortality. Although there is no specific antidote for olanzapine overdose, appropriate history, assessment and early diagnosis are very useful for the better outcome.

Full Text Available Abstract Background Adolescents face many barriers to physical activity, demonstrated by the decline in physical activity levels in teenage populations. This study aimed to assess the feasibility of overcoming such barriers via the implementation of an activity-promoting voucher scheme to teenagers in deprived areas. Methods All Year 9 pupils (n = 115; 13.3 ± 0.48 years; 51 % boys from one secondary school in Wales (UK participated. Participants received £25 of activity vouchers every month for six months for physical activity or sporting equipment. Focus groups (n = 7, with 43 pupils, and qualitative interviews with teachers (n = 2 were conducted to assess feasibility, in addition to a process evaluation utilising the RE-AIM framework. Quantitative outcomes at baseline, five months (during intervention and twelve months (follow-up included: physical activity (accelerometer, aerobic fitness (12 min Cooper run and self-reported activity (PAQ-A. Motivation to exercise (BREQ-2 was measured three months post-baseline and at follow-up. Results Qualitative findings showed that vouchers encouraged friends to socialise through activity, provided opportunities to access local activities that pupils normally could not afford, and engaged both those interested and disinterested in physical education. Improvements in weekend moderate-to-vigorous physical activity and reductions in sedentary behaviour were observed in both sexes. Boys’ fitness significantly improved during the voucher scheme. ‘Non-active’ pupils (those not meeting recommended guidelines of 60 mins∙day−1 and those with higher motivation to exercise had higher voucher use. Conclusions Adolescents, teachers and activity providers supported the voucher scheme and felt the vouchers enabled deprived adolescents to access more physical activity opportunities. Voucher usage was associated with improved attitudes to physical activity, increased socialisation with

The Enright phenomenon describes the distortion in speed perception experienced by an observer looking sideways from a moving vehicle when viewing with interocular differences in retinal image brightness, usually induced by neutral density filters. We investigated whether the Enright phenomenon could be induced with monocular pupil dilation using tropicamide. We tested 17 visually normal young adults on a closed road driving circuit. Participants were asked to travel at Goal Speeds of 40km/h and 60km/h while looking sideways from the vehicle with: (i) both eyes with undilated pupils; (ii) both eyes with dilated pupils; (iii) with the leading eye only dilated; and (iv) the trailing eye only dilated. For each condition we recorded actual driving speed. With the pupil of the leading eye dilated participants drove significantly faster (by an average of 3.8km/h) than with both eyes dilated (p=0.02); with the trailing eye dilated participants drove significantly slower (by an average of 3.2km/h) than with both eyes dilated (p<0.001). The speed, with the leading eye dilated, was faster by an average of 7km/h than with the trailing eye dilated (p<0.001). There was no significant difference between driving speeds when viewing with both eyes either dilated or undilated (p=0.322). Our results are the first to show a measurable change in driving behaviour following monocular pupil dilation and support predictions based on the Enright phenomenon.

To document the observations of elementary school teachers (ESTs) in Ilorin, Nigeria on their practice of some types of corporal punishment (CP) that could result in eye injuries among their pupils. A short battery of questions that explored ESTs' observations on attitudes to, and knowledge of some commonly used CP practices was self-administered on 172 consenting teachers from six sampled schools. The potentials for their pupils to sustain eye injuries while receiving such CP practices were inferred from the usage of items with sharp and protruding ends to administer CP, and the application of CP onto pupils' body parts that are in close proximity to the eye such as the head and face. Only 50 of the 172 ESTs favored the practice of CP of pupils by their teachers. Analyses of several potentially moderating variables on this response such as ESTs' ages, years of EST teaching experience, school, and class or grade that EST teaches did not prove significant. Over three-quarters of ESTs (80.2%) had ever observed that pupils were being disciplined by ESTs with a cane. About a fifth of them had also observed that ESTs applied CP to the head (19.8%) and the face (16.3%) of pupils. Findings suggest that ESTs' commonly employed CP practices have significant injurious potential to their pupils' eyes. It is recommended that CP be abolished in elementary schools, and instead alternative nonabusive methods of disciplining erring pupils by teachers be introduced.
Full Text Available Research about bullying among school pupils in the Arab/Muslim population is scarce. This study evaluates the characteristics of bullying and its impact among school pupils in Oman via cross-sectional survey among eighth grade school pupils (n = 1,229 during the academic year 2006-2007. The participants were selected using stratified random selection among 6 administrative divisions of one the governorates in the country. Data were collected using self-completed structured questionnaires. This study found similar percentages of males and females (76% have experienced one form of bullying, and the majority of the incidents (80% occurred in the vicinity of the school. In almost half of the cases, the bullying was initiated by a student of the same age or older than the victim. The most common type of bullying encountered in this study was verbal (47.7%, followed by misuse (45.9%, physical (43.9%, and, finally, social isolation/exclusion (22.5%. Although the failure of an academic year was uncommon among victims of bullying, the number of pupils who missed 4–6 and ≥7 school days was higher among bullied pupils. If this study will withstand further research, educational initiatives are needed to mitigate the rate of bullying in Oman.

Full Text Available Introduction: the problem of development of a model of methods of forming the biological picture of the world of pupils as a multicomponent and integrative expression of the complete educational process is considered in the article. It is stated that the results of the study have theoretical and practical importance for effective subject preparation of senior pupils based on acquiring of systematic and generalized knowledge about wildlife. The correspondence of the main idea of the article to the scientific profile of the journal “Integration of Education” determines the choice of the periodical for publication. Materials and Methods: the results of the analysis of materials on modeling of the educational process, on specific models of the formation of a complete comprehension of the scientific picture of the world and its biological component make it possible to suggest a lack of elaboration of the aspect of pedagogical research under study. Therefore, the search for methods to overcome these gaps and to substantiate a particular model, relevant for its practical application by a teacher, is important. The study was based on the use of methods of theoretical level, including the analysis of pedagogical and methodological literature, modeling and generalized expression of the model of forming the biological picture of the world of secondary school senior pupils, which were of higher priority. Results: the use of models of organization of subject preparation of secondary school pupils takes a priority position, as they help to achieve the desired results of training, education and development. The model of methods of forming a biological picture of the world is represented as a theoretical construct in the unity of objective, substantive, procedural, diagnostic and effective blocks. Discussion and Conclusions: in a generalized form the article expresses the model of methods of forming the biological picture of the world of secondary school

In the education of pupils with Down syndrome, "simplifying" literal talk and concrete stimulation have typically played a dominant role. This explorative study investigated the extent to which teachers stimulated abstract cognitive functions via inferential talk during book-sharing and how pupils with Down syndrome responded. Dyadic interactions (N=7) were videotaped, transcribed and coded to identify levels of abstraction in teacher utterances and to evaluate the adequacy of pupil responses. One-third of the teachers' utterances contained high levels of abstraction and promoted inferential talk. Six of the seven children predominantly responded in ways which revealed inferential thinking. Dialog excerpts highlighted individual, contextual and interactional factors contributing to variations in the findings. Contrary to previous claims, the children with Down syndrome in the current sample appear able to draw inferences beyond the "here-and-now" with teacher support. This finding highlights the educational relevance and importance of higher-order cognitive stimulation of pupils with intellectual disabilities, to foster independent metacognitive skills.

To investigate the reliability of a biometric iris recognition system for personal authentication after cataract surgery or iatrogenic pupil dilation. This was a prospective, nonrandomized, single-center, cohort study for evaluating the performance of an iris recognition system 2-24 hours after phacoemulsification and intraocular lens implantation (group 1) and before and after iatrogenic pupil dilation (group 2). Of the 173 eyes that could be enrolled before cataract surgery, 164 (94.8%) were easily recognized postoperatively, whereas in 9 (5.2%) this was not possible. However, these 9 eyes could be reenrolled and afterwards recognized successfully. In group 2, of a total of 184 eyes that were enrolled in miosis, a total of 22 (11.9%) could not be recognized in mydriasis and therefore needed reenrollment. No single case of false-positive acceptance occurred in either group. The results of this trial indicate that standard cataract surgery seems not to be a limiting factor for iris recognition in the large majority of cases. Some patients (5.2% in this study) might need "reenrollment" after cataract surgery. Iris recognition was primarily successful in eyes with medically dilated pupils in nearly 9 out of 10 eyes. No single case of false-positive acceptance occurred in either group in this trial. It seems therefore that iris recognition is a valid biometric method in the majority of cases after cataract surgery or after pupil dilation.

Full Text Available Studies on cognitive effort have shown that pupil dilation is a reliable indicator of memory load. However, it is conceivable that there are other sources of effort involved in memory that also affect pupil dilation. One of these is the ease with which an item can be retrieved from memory. Here, we present the results of an experiment in which we studied the way in which pupil dilation acts as an online marker for memory processing during the retrieval of paired associates while reducing confounds associated with motor responses. Paired associates were categorized into sets containing either 4 or 7 items. After learning the paired associates once, pupil dilation was measured during the presentation of the retrieval cue during four repetitions of each set. Memory strength was operationalized as the number of repetitions (frequency and set-size, since having more items per set results in a lower average recency. Dilation decreased with increased memory strength, supporting the hypothesis that the amplitude of the evoked pupillary response correlates positively with retrieval effort. Thus, while many studies have shown that "memory load" influences pupil dilation, our results indicate that the task-evoked pupillary response is also sensitive to the experimentally manipulated memory strength of individual items. As these effects were observed well before the response had been given, this study also suggests that pupil dilation can be used to assess an item's memory strength without requiring an overt response.

Full Text Available The way and the level a school-aged pupil adapts to different learning systems are mainly influenced by the family, the social background, the educational background, all of which will later reflect upon school success. The theme of the present study places us on a new territory, being of interest for the specialists in the field of educational sciences, for all those who have concerns in the field of education, as well as for parents. Its main purpose has been the research of the impact this fact has on the students that returned to their homeland, who are at the early schooling stage, as well as how elementary teachers respond to the real needs of their adaptation through specialized psycho-pedagogical assistance to such children. The method used in this investigative approach was the questionnaire-based research. The study was carried out on elementary teachers from the Olt county, who, during the current school year, have enrolled remigrants pupils in their classroom. The study objectives were aimed at analyzing the factors involved in adapting remigrants pupils to schools
Full Text Available French language teachers in Slovene elementary and high schools think that the teachers must motivate pupils with different approaches to work in the classroom. They also estimate that if the student isn't motivated to work in the classroom, teacher's effort could improve the motivation. Teachers, therefore, believe in their work, in their knowledge and competences to present French language to the pupils in the way they enjoy studying it, and that their way of work improves interest for the knowledge/learning of French language. Nevertheless, 78 % of teachers involved in this research think that a workshop about motivation with the examples from the good practice could be of great use to them. The analysis shows that teachers like to use student's book in their work and that they most often motivate pupils with their own excitement about the topic. The fact is that the motivation is a dynamic process which changes in time and in place. Teacher is a part of that process, but he/she is not the only one responsible for its outcome.

Full Text Available In available studies of inclusive practice and IEP, emphasis was placed on the activities undertaken to reach the accessibility of teaching programs for students with special needs. Architectural accessibility of schools and its implementation for IEP has not been researched enough. The main aim of this research was to highlight the importance of architectural barriers for the process of creating IEP for pupils with physical disabilities, trough determining a current situation in regular elementary schools in Belgrade. An observation list, with 38 variables of architectural accessibility was used in this research. The sample consisted of 12 elementary schools in “Zvezdara” Municipality, Belgrade. The results show that there is complete architectural accessibility in nine out of 38 variables. All nine variables belong to “universal design”. In other variables, elements that measure specific components of architectural accessibility for pupils with physical disabilities mainly intermit. This must be taken into consideration when we discuss IEP, primarily from the aspect of planning additional help and support to professionals, providing additional time for pupils’ work and learning in class, and providing adequate place for learning.

Recent research suggests profound sex and sexual orientation differences in sexual response. These results, however, are based on measures of genital arousal, which have potential limitations such as volunteer bias and differential measures for the sexes. The present study introduces a measure less affected by these limitations. We assessed the pupil dilation of 325 men and women of various sexual orientations to male and female erotic stimuli. Results supported hypotheses. In general, self-reported sexual orientation corresponded with pupil dilation to men and women. Among men, substantial dilation to both sexes was most common in bisexual-identified men. In contrast, among women, substantial dilation to both sexes was most common in heterosexual-identified women. Possible reasons for these differences are discussed. Because the measure of pupil dilation is less invasive than previous measures of sexual response, it allows for studying diverse age and cultural populations, usually not included in sexuality research.

Full Text Available It has been shown that negative affect causes attentional narrowing. According to Easterbrook’s (1959 influential hypothesis this effect is driven by the withdrawal motivation inherent to negative emotions and might be related to increases in arousal. We investigated whether valence-unspecific increases in physiological arousal, as measured by pupil dilation, could account for attentional narrowing effects in a cognitive control task. Following the presentation of a negative, positive, or neutral picture, participants performed a saccade task with a prosaccade versus an antisaccade instruction. The reaction time difference between pro- and antisaccades was used to index attentional selectivity, and while pupil diameter was used as an index of physiological arousal. Pupil dilation was observed for both negative and positive pictures, which indicates increased physiological arousal. However, increased attentional selectivity was only observed following negative pictures. Our data show that motivational intensity effects on attentional narrowing can occur independently of physiological arousal effects.
Full Text Available Game flow experience in the use of games has the potential of determining whether games used for learning would achieve the desired goal of improved achievement. With a subject like Mathematics, it is vital to ensure that if game based strategies are to be used, the games must possess this very important construct. Furthermore, the games must be able to produce the flow experience in both males and females, so that the observed gender gap in the learning of the subject would not be further widened. It is therefore important to investigate the gender differences in a game based learning environment for a subject such as Mathematics. This is the purpose of this research. This research investigated games, game flow, and gender as they affect Mathematics achievement of pupils in Nigeria. Through the use of Achievement of Pupils in Fraction-concepts Test (APFT and Game Flow Questionnaire (GFQ, data were collected. The result was a significant difference in mathematics achievements of pupils exposed to game based strategy and those exposed to modified conventional method of teaching. However, there was no significant difference in game flow experiences, as well as in mathematics achievement of male and female pupils exposed to game based strategy.

Walking to school could improve pupils' health condition and might also reduce the use of motorized transport modes, which leads to both traffic congestion and air pollution. The current study aims to examine the role of parental risk judgements (i.e. risk perception and worry), transport safety attitudes, transport priorities and accident experiences on pupils' walking and mode choices on school trips in Iran, a country with poor road safety records. A total of 1078 questionnaires were randomly distributed among pupils at nine public and private schools in January 2014 in Rasht, Iran. Results from valid observations (n=711) showed that parents with high probability assessments of accidents and strong worry regarding pupils' accident risk while walking were less likely to let their children walk to school. Parents with high safety knowledge were also more likely to allow their pupils to walk to school. Parents who prioritized convenience and accessibility in transport had a stronger tendency to choose motorized modes over walking modes. Also, parents who prioritized safety and security in transport were less likely to allow pupils to walk to school. Elasticities results showed that a one percent increase in priorities of convenience and accessibility, priorities of safety and security, car ownership and walking time from home to school reduced walking among pupils by a probability of 0.62, 0.20, 0.86 and 0.57%, respectively. A one percent increase in parental safety knowledge increased the walking probability by around 0.25%. A 1 unit increase in parental probability assessment and worry towards pupils' walking, decreased the probability of choosing walking mode by 0.11 and 0.05, respectively. Policy-makers who aim to promote walking to schools should improve safety and security of the walking facilities and increase parental safety knowledge. Copyright © 2017 Elsevier Ltd.

This study is conducted in Singapore, where learning to read in English is regarded as essential because it is offered as a First Language (L1) subject in the curriculum and is stipulated as the medium of instruction in the education system, and the mother tongues are offered as Second Language (L2) subjects, although the majority still learn English as an L2. The paper reports on the reading strategies used by Singaporean primary school pupils from a cognitive perspective, which is part of a larger study that aims to investigate these pupils' language learning strategies. The participants were 18 pupils from three neighbourhood primary schools, in grades Primary 4, 5 and 6. The data were collected from high- and low-proficiency pupils at each of the three grades in each school, who read two texts at each level. Grounded in an information-processing theory and based on successful experiences of scholars using think-aloud for data collection, we asked the pupils to read and report what they were thinking about while reading. The think-aloud protocols were recorded, transcribed verbatim, coded and analysed. The results suggest that participants' flexible and appropriate use of reading strategies varies according to language proficiency and grade level, with the high-proficiency group outperforming its lower-proficiency counterpart and the high-graders outnumbering the lower-graders in terms of the number of strategies that they used. These differences were also exemplified with qualitative findings from case studies. The use of reading strategies differs according to proficiency levels, and the quality of pupils' strategy-use patterns has more significant implications for understanding efficient reading among primary school pupils.

Determination of the time since death in the early postmortem period is one of the most critical issues to be faced by criminal investigators. One of the techniques is the evaluation of the pupil pharmacological reactivity. In the present work, we aim at identifying whether an objective and single method, based on pharmacological pupil reaction, is feasible or not. Between 2002 and 2003 calendar years, we observed 309 bodies, whose eyes have been each instilled apart, within 26 hours since death, with either a myotic substance or a mydriatic solution. Our results show that the real effectiveness of pupil pharmacological reactivity as method for assessing the time since death in early postmortem period is not only questionable but even highly misleading if not replaced by alternative objective physiological tests and appropriate professional judgments by the investigators.

Full Text Available Background and objectives: The genus Colchicum belongs to the family Colchicaceae, which comprises of 19 genera, and 225 species worldwide. They have been recognized for more than 2000 years for their noticeable biological properties. The Colchicum species are well known for presence of tropolonic alkaloids, mainly colchicine. Colchicine, is still the drug of choice for treatment of gout, and is used for the treatment of a number of proinflammatory disorders, such as familial Mediterranean fever, and Behcet’s disease. Clinical studies have proved colchicine to posses potent anti-tumor activity. Colchicum speciosum Steven is an indigenous perennial herbaceous plant widely distributed in northern, central and western regions of Iran. Methods: In the present study, the phytochemical composition of MeOH extract from bulbs of C. speciosum collected fromSavadkouh region, Iranwas investigated by combination of HPLC-PDA-MS spectrometry and NMR specroscopy. The fractionation of MeOH extract was carried out by partitioning on CH2Cl2, EtOAc and water. Results: The isolation and purification of CH2Cl2 portion by combination of reverse and normal phase chromatography resulted in the isolation, purification and identification of two new tropolonic alkaloids, compounds (1 and (2, as well as two known compound colchicine (3 and demecolcine (4. Their structures were established by extensive spectroscopic methods, including 1D (1H NMR and 2D-NMR (COSY, HSQC and HMBC. The absolute configurations of isolated compounds were established by aid of circular dichroism. Conclusion: Phytochemical investigation of CH2Cl2 extract of C. speciosum by combination of HPLC, column chromatography and hyphenated spectroscopic techniques led to identification two new alkaloids with potential as lead compounds.
decrease of viability index in group of children using computer for a long time (3 hours per day and more. In children go in for sport, there are significantly higher quality of life indexes determined by the scale of psychological health and by the scale of general health. Besides, in older children sleeping 8 hours per night, a sufficiently higher emotional stability is noticed determined by the scale of role-emotional functioning (p < 0.05. Conclusions. The diet of high school pupils does not meet the established standards. This may be a risk factor for gastroduodenal pathology in the future, and therefore requires systematic correction. In addition to rational nutrition, factors affecting the health status and the psycho-emotional status of high school pupils are controlled physical activity, regular outdoor exercise and limited use of the computer. The method of assessing the quality of life is a simple and informative mean for comprehensive study of the health status of high school pupils and can be recommended for widespread use in pediatrics.

The biased positioning of faces exposed to viewers of Western portraiture has suggested there may be fundamental differences in the lateralized expression and perception of emotion. The present study investigates whether there are differences in the perception of the left and right sides of the face in real-life photographs of individuals. The study paired conscious aesthetic ratings of pleasantness with measurements of pupil size, which are thought to be a reliable unconscious measure of interest first tested by Hess. Images of 10 men and 10 women were taken from the left and right sides of the face. These images were also mirror-reversed. As expected, we found a strong preference for left-sided portraits (regardless of original or mirror-reversed orientation), such that left hemifaces elicited higher ratings and greater pupil dilation. Interestingly, this effect was true of both sexes. A positive linear relationship was also found between pupil size and aesthetic ratings such that pupil size increased with pleasantness ratings. These findings provide support for the notions of lateralized emotion, right-hemispheric dominance, pupillary dilation to pleasant images, and constriction to unpleasant images.

In this article we address "language approach" data as a key variable in quantitative, large-scale research on educational achievement, focusing on our work for the Achievements of Deaf Pupils in Scotland (ADPS) project. The complexity of approaches is addressed, with a particular focus on a "no-exclusion" model of service. In this context 3 years of language-related data are discussed, using constructions of language variables that take into account the variability in deaf pupils' hearing loss levels, types of provision, and professional practice. We see this as a necessary first step toward offering a nuanced context for understanding patterns in the educational outcomes among the ADPS population to be reported in a later article. The ADPS data on language approach can reveal general patterns at macro levels: our analysis suggests that, in Scotland, the extent and quality of British Sign Language/English provision may be determined more by local factors than by linguistic requirements and that ostensibly responsive policies can mask a limited spectrum for pupils and their families. However, the ADPS data are insufficiently sensitive to detailed and local variations to reflect the full complexity of language situations over time-a situation which represents an ongoing challenge for all long-term, large-scale studies.

To report a successful osteo-odonto keratoprosthesis (OOKP) procedure in a case of end stage of corneal blindness due to Stevens-Johnson syndrome (SJS). An interventional case report. We describe a 35-year-old Indian woman, a known case of SJS with bilateral dry eyes and corneal blindness (failed corneal graft with vascularised total corneal opacity in the right eye and non-healing corneal ulcer in the left eye). Vision was hand movement only in both eyes. The corneal ulcer healed with medical treatment resulting in vascularised total corneal opacity with no improvement in vision. OOKP was performed in the right eye and the vision was improved from hand movement to 6/6. The same vision was maintained in the right eye at the last follow-up 5 years after surgery. OOKP provides good visual rehabilitation with long-term anatomically stable prosthesis in patients with end-stage of ocular surface disorders and corneal blindness secondary to SJS.

Usage of YouTube as an educational tool is gaining attention in academic research. To date, there has been no study on the content and quality of eye surgery videos on YouTube. The aim of this study was to analyze YouTube videos on phacoemulsification in eyes with small pupil. We searched for the phrases "small pupil cataract surgery," "small pupil phacoemulsification," "small pupil cataract surgery complications," and "small pupil phacoemulsification complications" in January 2015. Each resulting video was evaluated by all authors, and Krippendorff's alpha was calculated to measure agreement. Videos were classified according to pupil size (small/very small) in the beginning of the surgery, and whether pupillary diameter was large enough to continue surgery safely after pupillary dilation by the surgeon in the video (safe/not safe). Methods of dilatation were also analyzed. Any stated ocular comorbidity or surgical complications were noted. A total of 96 videos were reviewed. No mechanical intervention for pupillary dilatation was performed in 46 videos. Fifty-eight operated eyes had no stated ocular comorbidity. Ninety-five operations ended successfully without major complication. There was fair agreement between the evaluators regarding pupil sizes (Kα = 0.670) but poor agreement regarding safety (Kα = 0.337). YouTube videos on small pupil phacoemulsification have low complication rates when compared to the literature, although no reliable mechanical dilatation methods are used in almost half of these videos. Until YouTube's place in e-learning becomes clearer, we suggest that viewers be cautious regarding small pupil phacoemulsification videos on YouTube.

We describe the case history of a 9-year-old boy who developed Stevens-Johnson syndrome (SJS) following concomitant use of valproic acid and lamotrigine. He presented with rash and fever several weeks after introduction of lamotrigine, having been on valproic acid for seizure disorder. SJS happens to be one of the rare adverse reactions of antiepilepsy drugs (AED). Management is mainly supportive with care escalation when necessary because of the significant morbidity.

Professor Steven L. Wechsler, a world-renowned eye researcher and virologist, passed away unexpectedly on June 12, 2016 at the age of 68. Many scientists came to know Professor Wechsler as a gifted researcher in the field of ocular Herpes Simplex Virus (HSV-1) latency, reactivation, and pathogenesis. Professor Wechsler published over 150 peer-reviewed scientific papers during his career, pushing forward the frontiers of his field eye research. His colleagues would say, 'Steve literally wrote the book on herpes latency and reactivation.' He was the first to show that the HSV-1 latency-associated transcript (LAT) is essential for the HSV-1 high spontaneous reactivation phenotype and that LAT has anti-apoptosis activity. This discovery of LAT's anti-apoptosis activity, which is a key factor in how the LAT gene enhances reactivation, was published in Science in 2000 and created a new paradigm that greatly increased understanding of HSV-1 latency and reactivation. In collaboration with Professor Lbachir BenMohamed, an immunologist, they later demonstrated that LAT also acts as an immune evasion gene. He was a caring scientist who truly enjoyed working and sharing his experience and expertise with young researchers. He will be remembered as a significant pillar within scientific and ocular herpes research communities worldwide. Professor Wechsler's dedication to science, his compassionate character, and wonderful sense of humor were exemplary. We, who were his friends and colleagues, will mourn his passing deeply.

Food and drink purchasing habits of pupils out of school at lunchtime may be contributing to poor dietary intakes and overweight and obesity. The aim of this study was to identify the places from which purchases were made, types of food and drinks purchased and, the reasons for purchasing food or drinks out of school. A survey of the food and drinks purchasing habits of secondary school pupils (11-16 yrs) out of school at lunchtime was conducted in Scotland in 2010. A face-to-face interview and a self-completion questionnaire was designed to identify the food outlets used at lunchtime, types of food and drinks purchased and pupils' reasons for purchasing food or drinks out of school. Height and weight were measured and BMI centiles used to classify pupils as normal weight, overweight or obese. Results were compared by age group, sex, BMI group and level of socio-economic deprivation. Of the 612 pupils who completed the survey, 97 % reported having access to places selling food or drinks out of school at lunchtime, and of these 63 % made purchases. A higher proportion of pupils from more deprived areas reported purchasing food or drinks out of school, but the proportion making purchases did not differ significantly by sex or BMI group. Supermarkets were the outlets from which pupils reported most often making purchases, with fewer purchasing food or drinks from fast food takeaways, and this did not differ significantly by socio-economic deprivation. Reasons for making purchases included availability of preferred food and drinks, some of which are restricted for sale in schools, and social reasons, such as wanting to be with friends. Sandwiches and non-diet soft drinks were items most commonly purchased, followed by confectionery and diet soft drinks. However, less than 10 % of all the secondary school pupils reported purchasing these foods every day. Supermarkets, not just fast food outlets, should be considered when developing strategies to improve the dietary

Full Text Available Iris segmentation in the iris recognition systems is a challenging task under noncooperative environments. The iris segmentation is a process of detecting the pupil, iris’s outer boundary, and eyelids in the iris image. In this paper, we propose a pupil localization method for locating the pupils in the non-close-up and frontal-view iris images that are captured under near-infrared (NIR illuminations and contain the noise, such as specular and lighting reflection spots, eyeglasses, nonuniform illumination, low contrast, and occlusions by the eyelids, eyelashes, and eyebrow hair. In the proposed method, first, a novel edge-map is created from the iris image, which is based on combining the conventional thresholding and edge detection based segmentation techniques, and then, the general circular Hough transform (CHT is used to find the pupil circle parameters in the edge-map. Our main contribution in this research is a novel edge-map creation technique, which reduces the false edges drastically in the edge-map of the iris image and makes the pupil localization in the noisy NIR images more accurate, fast, robust, and simple. The proposed method was tested with three iris databases: CASIA-Iris-Thousand (version 4.0, CASIA-Iris-Lamp (version 3.0, and MMU (version 2.0. The average accuracy of the proposed method is 99.72% and average time cost per image is 0.727 sec.

We tested the link between pupil size and the task effort involved in covert shifts of visual attention. The goal of this study was to establish pupil size as a marker of attentional shifting in the absence of luminance manipulations. In three experiments, participants evaluated two stimuli that were presented peripherally, appearing equidistant from and on opposite sides of eye fixation. The angle between eye fixation and the peripherally presented target stimuli varied from 12.5° to 42.5°. The evaluation of more distant stimuli led to poorer performance than did the evaluation of more proximal stimuli throughout our study, confirming that the former required more effort than the latter. In addition, in Experiment 1 we found that pupil size increased with increasing angle and that this effect could not be reduced to the operation of low-level visual processes in the task. In Experiment 2 the pupil dilated more strongly overall when participants evaluated the target stimuli, which required shifts of attention, than when they merely reported on the target's presence versus absence. Both conditions yielded larger pupils for more distant than for more proximal stimuli, however. In Experiment 3, we manipulated task difficulty more directly, by changing the contrast at which the target stimuli were presented. We replicated the results from Experiment 1 only with the high-contrast stimuli. With stimuli of low contrast, ceiling effects in pupil size were observed. Our data show that the link between task effort and pupil size can be used to track the degree to which an observer covertly shifts attention to or detects stimuli in peripheral vision.
Full Text Available The education system in Northern Ireland is characterized by division, with around 95% of the pupil population attending predominantly co-religionist schools. In a society that is transitioning from a thirty year conflict that has been framed by hostilities between the main Catholic and Protestant communities, reconciliation interventions in education have sought to promote the value of intergroup contact between pupils attending separate schools. Some qualitative research suggests that such initiatives are more likely to have positive outcomes for pupils from more middle class backgrounds than those from more disadvantaged communities and areas that experienced high levels of conflict related incidents and deaths during the pre-ceasefire years. Drawing on contact theory and empirical evidence from a large scale quantitative study, we seek to examine this theory. Using free school meals as a proxy for social class, our findings are consistent in finding that there is a differential impact of contact for those from less affluent backgrounds, and we conclude by arguing that this should be reflected in policy responses.

Full Text Available The efficacy of parents’ meetings in primary schools in the UK is anarea in need of research. This article uses an approach informed by grounded theory to explore the experiences and satisfaction of parents, teachers and pupils regarding bi-annual meetings to discuss pupil progress. A two-phase approach was utilised, with diary-interviews with parents and teachers and group pupil interviews in Phase 1, followed by a parents’ questionnaire in Phase 2 derived from Phase 1 data. The findings from a doctoral study provide an overall more positive depiction of these meetings compared to existing research in the secondary sector. A model of the teacher as the expert and information-giver persists, but a consumerist ideology appears evident as parents seek to participate and advocate on behalf of their child. As parents become more proactive and teachers act to retain their professional authority, the interaction of the professional and advocate has excluded the perspective of the child. This leaves pupils in search of self-advocacy at meetings in which they are the object of discussion, but cannot be present. While pupils generally favour involvement, adults express a protectionist perspective on pupil exclusion with exceptional factors indicated as being the age of the child and the content of the meeting.

The criteria for brain death in Japan include a bilateral pupil diameter of ≥4 mm. We evaluated the appropriateness of a 4-mm pupil diameter in adult brain-dead donors in Japan. We retrospectively reviewed the records of 148 consecutive adult brain-dead donors with an average age of 46 years. All records were anonymously registered to the Japanese Ministry of Health, Labour and Welfare (the Japanese Ministry of Health and Welfare before 2001) from the various designated emergency institutes that performed organ donation under brain death from 1999 to 2012 in Japan. All donors had a Glasgow Coma Scale score of 3, absence of all seven brain stem reflexes, an isoelectric electroencephalogram for >30 min, and apnea as tested by the standard method. All of these examinations were repeated approximately 6 h later for confirmation. The pupil diameter (average ± standard deviation) was 6.1 ± 1.1 mm at the first assessment and 6.4 ± 1.1 mm approximately 6 h later. The 95% probability distribution as calculated by statistical analysis was 3.93-8.30 mm in the left eye and 3.88-8.28 mm in the right eye in the first assessment, and 4.25-8.58 mm in the left eye and 4.32-8.43 mm in the right eye approximately 6 h later. Despite the various original causes of brain death, we conclude that a pupil diameter of ≥4 mm is a reasonable criterion for brain death in adults.

One of the most dangerous dermatologic emergencies is Stevens-Johnson Syndrome (SJS)/toxic epidermal necrolysis (TEN). Although a rare disease, it can often lead to significant mortality. In this case report, we present a 77-year-old man who developed a sloughing rash that was secondary to a nonsteroidal anti-inflammatory drug. In addition to the recommended supportive care, the patient was treated with etanercept, a new, less commonly used intervention. We provide a brief review of SJS/TEN. Nonsteroidal anti-inflammatory drugs are a rare cause of SJS/TEN, and additionally, the use of biologics is a novel treatment modality for SJS/TEN.

Full Text Available In this study, we evaluated the repeatability of pupil responses to colored light stimuli in healthy subjects using a prototype chromatic pupillometer. One eye of 10 healthy subjects was tested twice in the same day using monochromatic light exposure at 2 selected wavelengths (660 nm and 470 nm, intensity 300 cd/m2 presented continuously for 20 seconds. Pupil responses were recorded in real time before, during and after light exposure. Maximal contraction amplitude and sustained contraction amplitude were calculated. In addition, we quantified the summed pupil response during continuous light stimulation as the total area between a reference line representing baseline pupil size and the line representing actual pupil size over 20 seconds (area under the curve. There was no significant difference in the repeated measure compared to the first test for any of the pupil response parameters. In conclusion, we have developed a novel prototype of color pupillometer which demonstrates good repeatability in evoking and recording the pupillary response to a bright blue and red light stimulus.

In this paper, we present the design and application of a teaching scenario appropriate for 12-years-old pupils in the primary school aiming to a better understanding of scientific concepts and scientific methods, linking the development of individual thinking with the development of scientific ideas and facilitating a better understanding of the nature of science. The design of the instructional material supporting this scenario has been based on the study of the history of astronomy and especially on: (a) The various theories concerning the movement of Earth, our solar system and the universe. (b) Key-stories highlighting the evolutionary character of scientific knowledge as well as the cultural interrelations of science and society. The design of the teaching scenario has focused on the participation of pupils in gradually evolving discourses and practices encouraging an appreciation of aspects of the nature of science (e.g. the role of observation and hypothesis, the use of evidence, the creation and modification of models). In this case, pupils are asked to produce their own narratives: animation movies concerning the geocentric-heliocentric debate inspired by the history of science, as the animation technique presents strong expressional potential and currently has many applications in the field of educational multimedia. The research design of this current case study has been based on the SHINE research model, while data coming from pupils' animation movies, questionnaires, interviews, worksheets, story-boards and drawings have been studied and analyzed using the GNOSIS research model. Elaborated data coming from our analysis approach reveal the appearance, transformation and evolution of aspects of nature of science appreciated by pupils and presented in their movies. Data analysis shows that during the application pupils gradually consider more and more the existence of multiple answers in scientific questions, appreciate the effect of culture on the way

In this paper, we show that by using a “pinwheel” architecture for the segmented primary mirror and curved supports for the secondary mirror, we can achieve a near uniform diffraction background in ground and space large telescope systems needed for high SNR exoplanet science. Also, the point spread function will be nearly rotationally symmetric, enabling improved digital image reconstruction. Large (>4-m) aperture space telescopes are needed to characterize terrestrial exoplanets by direct imaging coronagraphy. Launch vehicle volume constrains these apertures are segmented and deployed in space to form a large mirror aperture that is masked by the gaps between the hexagonal segments and the shadows of the secondary support system. These gaps and shadows over the pupil result in an image plane point spread function that has bright spikes, which may mask or obscure exoplanets.These telescope artifact mask faint exoplanets, making it necessary for the spacecraft to make a roll about the boresight and integrate again to make sure no planets are missed. This increases integration time, and requires expensive space-craft resources to do bore-sight roll.Currently the LUVOIR and HabEx studies have several significant efforts to develop special purpose A/O technology and to place complex absorbing apodizers over their Hex pupils to shape the unwanted diffracted light. These strong apodizers absorb light, decreasing system transmittance and reducing SNR. Implementing curved pupil obscurations will eliminate the need for the highly absorbing apodizers and thus result in higher SNR.Quantitative analysis of diffraction patterns that use the pinwheel architecture are compared to straight hex-segment edges with a straight-line secondary shadow mask to show a gain of over a factor of 100 by reducing the background. For the first-time astronomers are able to control and minimize image plane diffraction background “noise”. This technology will enable 10-m segmented

20 years ago, Michael Schnitzler founded the NGO "Rainforest of the Austrians" to help save one of the most diverse rainforests in Central America, the Esquinas rainforest on the Pacific coast of SW Costa Rica, from being destroyed through logging. In this abstract we present an interdisciplinary upper Austrian school project aiming at building positive awareness in pupils towards rainforest conservation by fund-raising to help purchase endangered forest areas. The acquired rainforest was donated to the Costa Rican government and became part of the National Park "Piedras Blancas". In the following, we present a chronology of events and actions of the school project. We started our rainforest project by face-to-face encounters, letting involved persons speak directly to the pupils. Dr. Huber, coordinator of the tropical rainforest station La Gamba in Costa Rica (www.lagamba.at), together with Dr. Weissenhofer, presented an introductory slide show about the "Rainforest of the Austrians". With rainforest images and sounds in their mind the pupils wrote "trips of a lifetime" stories, thus creating idyllic images of rainforest habitats. Following up on that, we visited the exhibition "Heliconia and Hummingbirds" at the Biology Center in Linz. Reports about the slide show and the exhibition followed. Tropical sites were compared by producing climate graphs of La Gamba, Costa Rica, and Manaus in Brazil. The global distribution and the decrease of rainforests were also analyzed. In biology lessons the symbiosis between plants and animals of the rainforest were worked out by searching the Internet. Flyers with profiles of rainforest animals were produced. We also discussed the ecotourism project "RICANCIE" in Ecuador using fact sheets. "RICANCIE" is a Spanish acronym standing for "Indigenous Community Network of the Upper Napo for Intercultural Exchange and Ecotourism". It was founded in 1993 aiming to improve the quality of life for some 200 indigenous Kichwa families

Full Text Available Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the etiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy.

Full Text Available The main aim of this article is to answer the following research question: How can we prepare student teachers to deal with pupils who have a wide range of day-to-day experiences of the digital world? This question arises out of the understanding that today's student-teacher training is inadequately equipped to realize the potential for learning found in the way that digital technology is now an integral part of the social and cultural practices of children and young people. Based on theory and practice from research and development activities in primary and lower secondary school, the article points out some perspectives connected to the technology culture of children and young people that may have importance for the professional training of student teachers. The article concludes by summarizing some findings from a research project in general teacher education, where it is argued that student teachers can be qualified to cope with the way children and young people use technology by teaching them to adopt solutions based on personal publishing. In many ways the article deals with classical issues in the education field; how the relations between cognition, learning, technology and fellow-citizenship raise practical issues connected to teaching and learning (Dewey, 1915; 1938; 1958.
Full Text Available Introduction: to day, physical fitness testing often causes negative emotions in pupils. It results in sharp loss of pupils’ wish to fulfill physical exercises in free time and worsens their health. Possibility to assess health level is an important motivation factor for pupils’ passing physical tests. Objective testing system will form positive motivation for physical exercises’ practicing and will facilitate increase of pupils’ motor functioning. It will also facilitate optimization of their physical condition, improvement of physical fitness and strengthening of health. Material: we tested physical fitness level and made diagnosis of pupils’ functional state (10-15 years’ age; n=85 with the help of tool methodic. We also used regressive analysis. Results: the system of tests and standards for express-control over physical fitness and health of middle school age pupils has been worked out and substantiated. The system of tests envisages fulfillment of 4 exercises: back pressing ups on bench during 20 seconds; throwing and catching of ball with two hands from wall during 30 seconds; side bending; torso rising from lying position into sitting during 30 seconds. Integral indicator of pupils’ physical fitness and health correlates with functional state of organism’s leading systems. We worked out 5 levels’ scale for express-control over physical fitness and health of middle school age pupils. The system stipulates calculation of integrative indicator with the help of regression equation by results of 4 test exercises and calculation of one index. Conclusions: The system of tests and standards permits the following: to divide pupils into relatively uniform groups even at the beginning of academic year for successful reasonable physical load. The system also permits to determine standard and find what shall be strived for by a pupil in order to achieve optimal physical fitness and somatic state; to motivate relatively weakly

Since 1995 all Swedish compulsory schools have been required to establish Individual Educational Plans (IEPs) for pupils with special educational needs. According to the Swedish Education Act such a plan should be drawn up if pupils do not achieve the goals in the curriculum or the syllabus. The process of IEPs covers a prior investigation to…
Full Text Available In the article the author’s experience in pupils’ training of Junior Academy of Sciences of Ukraine to research work by means of informational and communication technologies. The three-tiered approach (popular science, experimental, fundamental levels to the organization of personal oriented study in Physics covered such didactic principles as accessibility, visibility, scientific and systematic is considered. At the first level, pupils should be inculcated by interest in physics, its specificity, the terms etc. At the second level the experiment and demonstration of physical phenomena have a paramount importance, which aims to encourage students to make self-facilitated conclusions. At the third level the laboratory works and method of problem learning allow students to develop the ability independently to solve physical tasks. It is concluded that at each of these levels the means of information and communication technologies should be used. As an example, the author reviews the experience of open online course «Introduction to Physics of Sound», designed for pupils of specialized out-of-school educational institutions. We presented the main issues of the online course and examples of cognitive activity of pupils

Seven hundred and ninety-eight preschool children and grade one pupils from three schools in the city of Shangqiu were sampled randomly in urban, suburban and rural areas. The transparent tape method was used to examine the infection of pinworm and the contamination of pinworm eggs on the environments. The average infection rate of pinworm was 9.9% (79/798). The prevalence of pinworm infection among the pupils of urban(4.6%) was statistically lower than those of suburban (11.2%) and rural (13.8%) (P pinworm eggs from armor, fingers, bedclothes, briefs,and stationery in infected pupils are 23.8% (5/21), 18.0% (9/50), 15.8% (3/19), 12.9% (4/31) and 5.0% (2/40), respectively, which showed no statistical significance (P > 0.05).

The study presented here investigated the effects of emotional valence on the memory for words by assessing both memory performance and pupillary responses during a recognition memory task. Participants had to make speeded judgments on whether a word presented in the test phase of the experiment had already been presented ("old") or not ("new"). An emotion-induced recognition bias was observed: Words with emotional content not only produced a higher amount of hits, but also elicited more false alarms than neutral words. Further, we found a distinct pupil old/new effect characterized as an elevated pupillary response to hits as opposed to correct rejections. Interestingly, this pupil old/new effect was clearly diminished for emotional words. We therefore argue that the pupil old/new effect is not only able to mirror memory retrieval processes, but also reflects modulation by an emotion-induced recognition bias.

Full Text Available Language experts claim that it is easier for pupils to learn when the mother tongue is used in the teaching learning process including the learning of a second language. This study determined the reading comprehension level of Grade I pupils in Bulusan Central School for school year 2013-2014 as input in developing big books written in the vernacular that can be used as reading materials for Grade 1 pupils. Results of the evaluation revealed that they belong to the frustration and instructional levels in the literal skill; mostly are frustration readers along interpretative and evaluative skills; but are independent readers along applied skills; hence, they have low level of reading comprehension. Based on the result of the study, three big books as MTB-MLE instructional materials in Bicol were produced to develop or enhance Grade 1 pupils’ reading comprehension. Teaching guides were likewise developed.

The educational system in Kuwait is undergoing some fundamental changes, and the need for reform of environmental education has become urgent as a result of the concerns of both the government and the public over environmental issues. It is in such a context that this research was conducted. The research was intended to develop, implement, and evaluate an experimental programme Man and Nutrition for Kuwaiti primary school pupils, aimed at developing a positive environmental achievement, Information about the present status of environmental concepts and environmental education in Kuwait was obtained from preliminary study such as interviews and curriculum analysis. Interviews were conducted in ten different primary schools in four districts in Kuwait, which involved 31 pupils in total, hi addition, information was obtained by analysis of the science curriculum for fourth grade primary schools. The preliminary study was carried out during the period April to October 1998. The results of the preliminary study served to aid the development of an experimental teaching programme. The experimental programme Man and Nutrition consisted of eight lessons printed in two booklets, a teacher's guide and pupil's textbook. The research included a review of the relevant literature examining the development of environmental programmes and activities in a number of countries, which were selected because of their environmental education approaches, and the variety of their environmental conditions. Pilot testing of the teaching programmes was carried out to ascertain the appropriateness of the materials and the data collecting instruments used for the evaluation of the main experimental study. The main study group included 115 pupils in four primary schools and four teachers selected in Kuwait. Data collecting included pre and post-tests and the course evaluation by teachers using semi-structured interviews. Statistical analysis of data obtained was carried out using the SPSS
significance of the differences in the items' mean at p ≤ 0.05. On the average, the results suggest that the majority of pupils in the sample, irrespective of the gender shared almost similar sentiments towards environmental protection issues and to a large extent, placed the same items on top as well as at the bottom of their ...
Most school nurses are not confident they can give essential support to pupils with long-term health conditions. Research by the National Children's Bureau found that, due to heavy workloads and the need to work across several schools, nine out of ten school nurses were less confident they can help children with conditions such as diabetes and asthma.

Physical activity at school can be beneficial to children?s psychosocial well-being. To realise this potential, a school environment that supports physical activity is crucial. Self-Determination Theory provides the basis for one approach, namely to focus on pupils? need to feel competent......, autonomous and related. The purpose of this study was to investigate how pupils experienced a school physical activity intervention based on Self-Determination Theory and to assess whether the components developed for the intervention appeared to increase the pupils? sense of competence, autonomy...... their sense of competence and autonomy. Changing the physical activity climate to focus on mastery and learning instead of competing and performance was challenging, but in some instances brought about more positive experiences, especially for pupils with limited motivation in school physical activity...

The subliminal mere exposure effect (SMEE) is the phenomenon wherein people tend to prefer patterns they have repeatedly observed without consciously identifying them. One popular explanation for the SMEE is that perceptual fluency within exposed patterns is misattributed to a feeling of preference for those patterns. Assuming that perceptual fluency is negatively correlated with the amount of mental effort needed to analyze perceptual aspects of incoming stimuli, pupil diameter should associ...
Full Text Available Background. Health status of young athletes — pupils of the schools of physical culture — remains unexplored. The purpose of the study was a comparative assessment of health status of young athletes, depending on their age, gender and sport. Materials and methods. Health status of 499 pupils of the school of physical culture (330 boys and 169 girls aged 12–19 years old, representatives of 14 sports was studied according to medical examination results and records in dispensary observation cards. Results. 72 % of pupils had electrocardiographic (ECG deviations from norm, 65 % — somatic and infectious diseases, 48 % — musculoskeletal system diseases, 35 % — traumatic injuries, 14 % — health status complaints, the incidence of which usually depended on children’s age and gender. Specificity of sport direction significantly affected the incidence of ECG abnormalities, less significantly influenced the rate of musculoskeletal system pathology and traumatic injuries, almost did not affect the incidence of other somatic and infectious diseases. Conclusions. The higher incidence of ECG abnormalities, diseases and traumatic injuries was observed in representatives of cyclic, technical sports, wrestling and pentathlon.

Full Text Available [b]Introduction.[/b] The dynamic rise of alcohol consumption in adolescents is a matter of serious concern, requiring frequently updated monitoring. By such means, it is possible to optimise preventative measures for dealing with this problem. [b]Objective[/b]. To estimate the magnitude/amount and frequency of alcohol consumed by middle and high school pupils in Poland, including the circumstances when alcohol was first drunk. [b]Materials and Methods[/b]. A randomised survey was performed throughout Poland on middle school (junior high school pupils, (n=9360 in 2009, followed by both middle and high school pupils in 2011 (n=7971. The questionnaire was devised by the Polish Chief Sanitary Inspectorate (GIS. [b]Results[/b]. A strikingly sharp increase in alcohol consumption (29% was observed in subjects between 2009 – 2011. In the latter year, 1 month prior to survey, respectively, 50% and 71% of middle school and high school pupils drank alcohol, and correspondingly, 36% and 63% of these pupils ever became intoxicated/drunk. [b]Conclusions[/b]. 1 Adolescent alcohol consumption increases with age and is highest in girls. Monitoring as well as in-depth analysis thus becomes necessary. 2 Systematic monitoring and analysis of changing healthy lifestyle behaviour should be used for taking the necessary corrective action. This should happen concurrently and consist of planned health education programmes, including health promotion.
Conclusions: Potential multifocal contact lens users may present with different ages, different jobs or hobbies and different preferences regarding lighting conditions and working distances. This results in different pupil size, even within the same task. This information may be critical when selecting a particular lens design and add power. Eye care practitioners are therefore advised to assess pupil diameter in real life conditions.

The present study investigated indoor climate and window opening behaviour by pupils, as well as their perceptions and symptoms in classrooms with different types of ventilation systems. Four classrooms were selected in the same school in suburban Denmark. Classroom ventilation was achieved either......-heating and heating seasons; CO2 concentration was used to estimate average classroom ventilation rates. At the end of each measuring period, the pupils were asked to report their perceptions of the indoor environment and their acute health-related symptoms. The classroom in which ventilation was achieved by manually...... operable windows had the highest air temperatures and CO2 concentrations during both non-heating and heating season; the estimated average air-change rate was lowest in this classroom. The classroom with mechanical ventilation had the highest estimated average air-change rate. Windows were frequently...
