Published: October 2018

Abstract:

Introduction: There are several statements about the connection between cardiovascular diseases and climate change. On behalf of our observation-based knowledge we hypothesized a relationship between the occurence of aortic aneurysm (AA) rupture and weather changes. Aim: The purpose of our study was to explore the relationship between fatal aortic catastrophe and changes in atmospheric pressure and temperature. By using a new method we could even measure the intensity of the connection. Method: We have developed a software earlier to examine the link between pulmonary embolism mortality and the weather on data sets comprised of aortic aneurysm cases, where the medical condition had led to the fatal rupture of the aorta. For the events mentioned earlier we used the autopsy database of Semmelweis University between January 1, 2005 and January 1, 2014. Altogether we examined 152 aneurysm-related aortic catastrophes. We reported the exact day of the incident and the weather conditions on that day and the day before. Results and conclusion: We have defined that the occurrence rate of fatal aortic catastrophe showed a slight dependence on the two examined parameters within our groups. We have found the connection related to ruptured aortic aneurysm and changes in atmospheric pressure more significant than their connection with mean daily temperatures. With the increase in atmospheric pressure, the rate of AA mortality also increased. In the knowledge of our results we believe that the mathematical model we used can be an effective starting point for population-based and prospective studies. Orv Hetil. 2018; 159(37): 1501–1505.
Sarcopenia és életminőség: a Sarcopenia Quality of Life (SarQoL) kérdőív hiteles magyar fordítása
Authors: Hodinka László , Vereckei Edit , Gasparik Andrea Ildikó
Published: October 2018

Abstract:

Introduction: Sarcopenia, or age-related muscle loss, is emerging as a serious public health concern. Due to the impaired physical performance associated with sarcopenia, a reduced quality of life (QoL) has been evidenced in the affected individuals. Generic instruments, such as Rand Corporation Short Form 36 (SF-36) or the European Quality of Life (EuroQoL-5D) questionnaires do not accurately assess the impact of sarcopenia on QoL. SarQoL (Sarcopenia Quality of Life) questionnaire, was the first disease-specific questionnaire addressing the quality of life in patients with sarcopenia and has been recently designed for providing a global assessment of the quality of life in community-dwelling elderly subjects aged 65 years and older. Aim: Our aim was the development of a valid Hungarian version of the original SarQoL, through the translation, cultural adaptation and content validation of the original questionnaire. Method: We followed the recommended process, the international protocol of translation in five steps: two initial translations, synthesis of the two translations, backward translation, expert committee to compare translations with the original questionnaire and pretest. The pretest process involved 20 subjects (10 clinically sarcopenic and 10 non-sarcopenic with different educational and socioeconomic backgrounds) who were asked to complete the questionnaire. Feedbacks were requested from all subjects regarding the comprehensibility of questions or difficulties in completing the test. Results: Using the recommended best practice protocol for translation, the pre-final version is comparable with the original instrument in terms of content and accuracy. Conclusion: After the content validation with clinically sarcopenic persons it should be a useful tool to assess the quality of life of people with sarcopenia among elderly Hungarian patients.

Abstract:

After a „silence” period for decades, a great body of new information has become available about the pathogenesis, diagnosis and treatment of gout. New data on purine metabolism and urate transporters have been published. It has become evident that gout is an autoinflammatory disease involving the inflammasome and interleukin-1. With respect to diagnosis, microscopic evaluation of the urate crystal is still the gold standard, however, sensitive imaging techniques (ultrasound, modern computed tomography methods) are able to visualize crystal deposition and tophus formation. Tophus size may also be monitored over time. We see a renaissance of non-pharmacological, lifestyle-related treatment modalities. Pharmacotherapy includes the resolution of attacks and urate-lowering maintenance therapy. In 2016, two recent series of recommendations have been published. Treat-to-target therapy aiming at urate levels ≤360 μmol/l is crucial. Urate-lowering therapy includes xanthine oxidase inhibitors (allopurinol, febuxostat). However, a number of novel compounds (urate transporter inhibitors, recombinant uricase, interleukin-1 inhibitors) are under development or before introduction to gout treatment. Comorbidites should be considered throughout the follow-up of gout patients. Orv Hetil. 2018; 159(40): 1625–1636.
PHYSICAL ACTIVITY, CARDIORESPIRATORY FITNESS AND METABOLIC SYNDROME IN ADOLESCENTS
Authors: Oliveira Raphael Gonçalves de , Guedes Dartagnan Pinto
Published: October 2018

ABSTRACT Introduction: Metabolic Syndrome (MetS) has been associated with sedentary behavior, low levels of physical activity and of cardiorespiratory fitness. However, in adolescents the results are conflicting. Objective: To measure the association between sedentary behavior, physical activity, cardiorespiratory fitness and MetS in a representative sample of adolescents. Methods: The sample consisted of 1,035 adolescents (565 girls and 470 boys) between 12 and 20 years of age. Sedentary behavior was treated through recreational screen time, while information equivalent to physical activity was considered through the Physical Activity Questionnaire for Adolescents. The maximal oxygen uptake (VO2max), estimated through PACER performance, was used as an indicator of cardiorespiratory fitness. MetS was identified using the criteria of the International Diabetes Federation. Results: Adolescents of both sexes identified with MetS had significantly longer recreational screen time and lower VO2max than their unidentified MetS peers. Scores equivalent to the level of physical activity undertaken by adolescents identified and not identified with MetS were statistically similar. Probabilistically, adolescents with high recreational screen time and low VO2max had, respectively, 79% [OR = 1.79; 95% CI 1.10 – 2.82] and 95% [OR = 1.95; 95% CI 1.20 – 3.09] greater odds of being identified with MetS. Conclusion: The findings indicate consistent and significant associations between longer recreational screen time, low VO2max values and high prevalence of MetS, which suggests specific interventions designed to help minimize cardiometabolic risk exposure from a very early age.

ABSTRACT The aim of this study was to synthesize and analyze scientific evidence of the perceived barriers to leisure-time physical activity (PA) in the Brazilian population. The Lilacs, SciELO, PubMed, ScienceDirect and Web of Science journal databases were reviewed and the number of reports of each barrier to PA, grouped according to the level of determinants of the social ecological model (intrapersonal, interpersonal and environmental) was analyzed. We found 25 studies (11 in adolescents, 8 in adults and 6 in older adults), totaling 62,678 reports of barriers to PA. The studies were conducted in the South (n=15), Southeast (n=7), and Northeast (n=2) regions, and one study also included different regions of Brazil. Overall, about seven out of every 10 reports on barriers to PA involved intrapersonal barriers. Adults and older adults had a higher proportion of reports of intrapersonal barriers (84.8% and 74%, respectively), than adolescents (47.8%). There are still few studies with older adults, children, and in populations of the Midwest and North of the country. The most frequently reported barriers to PA among adolescents were lack of company, lack of social support from family and friends, unsuitable climate and limited access to spaces for PA. Lack of motivation and lack of time were the most frequently reported barriers in adults, whereas in older adults the predominant barriers were lack of motivation and diagnosed disease or physical limitation. PA promotion programs need to take into account the different barriers to PA, since these are specific to age groups. Level of Evidence II; Systematic Review of Level II Studies.
SEDENTARY BEHAVIOR AND NUTRITIONAL STATUS AMONG OLDER ADULTS: A META-ANALYSIS

Published: October 2018

ABSTRACT The accelerated modernization process has entailed changes in the lifestyle of people, such as exposure to sedentary behavior, and this in turn may affect the nutritional status. The aim of this systematic review with meta-analysis was to analyze observational studies that assessed the association between exposure time to sedentary behavior and nutritional status (overweight/malnutrition) in individuals aged ≥60 years. BVS, PubMed and Web of Science were the databases used in the search for observational studies, published until November 28, 2017, which have examined the association between exposure time to sedentary behavior and nutritional status. Two authors undertook the reading of titles and abstracts and applied the STROBE checklist independently. The Odds Ratio was calculated using the random effects model. Eight studies were included in this meta-analysis and involved 21415 individuals. All the studies covered most of the items suggested by the STROBE checklist. Of the total, four studies showed association between sedentary behavior and nutritional status. Longer exposure to sedentary behavior did not increase the odds of overweight and/or obesity (OR 1.32; 95%; CI 0.95-1.84). It is suggested that further studies with standardized criteria for measuring sedentary behavior and nutritional status are undertaken. Level of Evidence II; Systematic review of level II studies.

Published: October 2018

ABSTRACT Introduction: The elastic wrap is widely used by different types of athletes and recreational practitioners of strength training in order to improve weightlifting performance. Objective: The objective was to investigate the acute effects of elbow wrap on strength performance, absolute volume, and rating of perceived exertion/discomfort during the bench press (BP) exercise. Methods: The experimental protocol was divided into three laboratory sessions. At the first session, a bench press familiarization phase was performed with (EW) and without (WEW) elastic elbow wrap. During the second session, the 1RM test was carried out in the bench press exercise under both EW and WEW conditions. At the third session, the repetition maximum (RM) test at 70% of 1RM (EW and WEW) was performed until concentric failure. After each session, subjects were consulted about their rate of perceived exertion (RPE), and discomfort (PSD). A paired student t-test was used to compare the values of 1RM and RMs with and without elastic wraps. Descriptive analysis was used for RPE and PSD. Results: For the 1RM test, there was a significant increase for the EW condition when compared to WEW (p<0.05). In the RMs test and absolute volume calculation, there was a significant increase for the EW condition (p<0.05). RPE did not differ in any of the conditions tested (p>0.05). PSD presented a high degree of discomfort with elastic wraps in all conditions. Conclusion: Elastic elbow wraps increase the load lifted in the 1RM test, and the maximum number of repetitions during the BP exercise, and consequently, the absolute volume. The elastic elbow wrap does not alter the subjective perception of effort, but it increases discomfort during exercise.
CYCLING TRAINING AND FUNCTIONAL ELECTRICAL STIMULATION FOR POST-STROKE PATIENTS
Authors: Shariat Ardalan , Ansari Noureddin Nakhostin , Shaw Brandon S. , Kordi Ramin , Kargarfard Mehdi , Shaw Ina
Published: October 2018

ABSTRACT Introducion: Stroke is one of the leading causes of morbidity and mortality in adults worldwide. The prevalence of stroke in developing countries such as South Africa and Iran is growing, especially in an increasingly younger population. In Iran, the annual stroke incidence ranges from 23 to 103 per 100,000 inhabitants, with the rate being higher in those aged 15-45 years. Problematically, almost 50% of stroke patients face difficulties in performing activities of daily living, hence the importance of functional rehabilitation. These factors necessitate cost-effective solutions in developing countries, where there is insufficient research focused on practical solutions for treatment/rehabilitation. Objective: We hypothesize that while progressive cycling training would activate cortical regions and that cycling speed feedback could lead to additional cortical activations and resultant improvements in cycling performance, combined cycling training and functional electrical stimulation would result in superior improvements in cycling performance, aerobic capacity, and functional performance in post-stroke patients. Conclusions: Ultimately, we expect this hypothesis to provide a useful framework for facilitating combined cycling and functional electrical stimulation rehabilitation research in post-stroke patient populations.

Railway bridge assessment for effective asset management
Authors: Griffin Mark , Patro Sivaji
Published: October 2018

Network Rail (NR) manages over 60 000 bridge spans, many of which are more than 150 years old. Having contemporary capability information for these ageing assets is vital for the safe and effective management of the rail network. NR has never before had comprehensive, contemporary capability information, and has relied on assessments up to 18 years old. In some cases, assets did not have assessments so their ongoing performance alone was relied upon. Without reliable data on the strength of these structures it would be impossible to operate the railway safely, deliver effective maintenance, decide when repair intervention is required or plan future development of the network. This paper describes the current approach to the assessment of bridges on the railway and the innovative work that has been undertaken to improve the efficiency of assessment and deliver the considerable volume of bridge assessments required to bring strength capability information to an acceptable standard. The paper will also explore the potential of consistent data collection and recording for the better management of the asset as it inevitably deteriorates.
Behaviour of a capping layer reinforced with recycled tyres
Authors: Sun Qideng , Indraratna Buddhima , Heitor Ana
Published: October 2018

In this paper, a sustainable approach for reducing lateral displacement in a track by increasing the confining pressure in the track substructure is demonstrated by placing a cellular rubber (tyre) membrane infilled with crushed ballast, as an alternative to a traditional capping layer of compacted granulates. Plate-load tests on a single tyre filled with gravel and subjected to a vertical load were carried out to investigate the interaction between tyre and gravel. A track model with tyre reinforcement was created to evaluate the performance of a tyre-reinforced capping layer under cyclic loading, and a numerical model was developed to determine the benefit that tyres would provide to railway substructure, especially when spent ballast is recycled as capping layer materials.
Analysis of the bearing behaviour of a screw-pile foundation in silt soil
Authors: Jiang Pengcheng , Xu Wang , Zhang Yanjie
Published: October 2018

Screw-pile composite foundations have been widely implemented on multiple high-speed railways in China. Their distinctive design with variable sections makes the bearing behaviour of screw piles far more complex than that of common smooth piles. The bearing behaviour of a screw-pile composite foundation was analysed in silt soil on a national key construction project. A comparative analysis of the bearing characteristics of composite foundations of smooth piles and screw piles was performed through model tests. The results showed that, in a single-pile composite foundation and with the same pile diameter and length, the ultimate bearing capacity of the screw pile was 67% higher than that of the smooth pile. The smooth pile showed an area of negative frictional resistance at the top of the composite foundation. The screw pile had a negative friction area below the junction of the smooth section and the screw section in the screw-pile composite foundation.
An optimisation method for a co-operative driving system at road junctions
Authors: Zhao Hongzhuan , Yue Hang , Gu Tianlong , Li Wenyong
Published: October 2018

A co-operative driving system for road junctions is an example of a vehicle cyber–physical system. It integrates the cyber systems in vehicles with their physical systems to optimise co-operative driving at traffic intersections. Depending on ‘vehicle-to-everything’ technology, the system can facilitate co-operation between moving vehicles and traffic control systems, improve traffic operation and management, and help vehicles negotiate junctions safely and efficiently. To optimise the system, an improved membrane-computing-based multi-vehicle optimisation method is proposed in this paper. The method is a potential solution to the multi-vehicle optimisation problem with constrained conditions and incommensurable objectives. It can better guarantee the safety of multiple moving vehicles at a junction than several traditional multi-objective optimisation methods. Experimental analyses show how the method can reduce delays at junctions, increase junction throughput and shorten overall journey times.
Effects of saline irrigation water and proline applications on yield, vegetative and physiological characteristics of potato crop (Solanum tuberosum L.)
Authors: ÖDEMİŞ Berkant , BÜYÜKTAŞ Dursun , ÇALIŞKAN Mehmet Emin
Published: October 2018

Potato
(Solanum tuberosum L.) is one of the most
important starch crops grown extensively. In this study, the effects of saline
water and proline content on yield and some characteristics of potato were
determined. Proline concentrations of 0 mM (control), 10 mM, and 20 mM were
applied to potato crop irrigated with water with electrical conductivities of
0.2 dSm-1 (control), 3.5 dSm-1, 7 dSm-1
10 dSm-1 and 13 dSm-1. Different levels of
saline irrigation water were obtained by adding NaCl into the tap water with an
EC of 0.2 dSm-1. In the saline water treatments, a leaching
fraction about 20% was applied.  The
study was conducted between January-June 2010 in the pots located in a
greenhouse under the Eastern Mediterranean (Hatay, Turkey) conditions. Compared
to the control treatment, the amount of irrigation water and crop water use
decreased by 4.5%-18.9% and 3.0%-16.0% depending on soil salinity,
respectively. Soil salinity caused a decrease in total tuber yield, mean tuber
weight, total dry weight, harvest index, and number of potatoes classified as
Grade A, whereas it caused an increase in total dry matter content. No distinct
effects of proline on tuber yield were observed in the treatments of higher
salt stress. The effect of increasing proline concentration was mostly
pronounced in the vegetative and gas exchange parameters.

A residência como modalidade de formação em Psicologia no Brasil: uma revisão sistemática da literatura
Authors: Rudá Caio
Published: October 2018

Já consagrada na educação médica, a residência tem ampliado seu nicho e se constituído, nos últimos anos, como uma alternativa de treinamento especializado para todo o espectro de profissões da saúde, proporcionando uma rica experiência profissional vinculada a um aprofundamento teórico. Resultado da sua aproximação com o setor público de saúde, o campo da Psicologia, não tem fugido a esse fenômeno, assinalando o surgimento de cada vez mais possibilidades de residência para os profissionais que buscam se aproximar das mais diversas áreas e temas de atuação na saúde, como a saúde da família, saúde do idoso, saúde mental, urgências, nutrição clínica, oncologia e outros mais. Nesse sentido, o estudo apresenta, através de uma revisão integrativa da literatura, o estado da arte acerca da formação do psicólogo em programas de residência. Para tanto, o levantamento abrange publicações indexadas nas bases de dados Lilacs, SciELO e PePSIC, identificando as primeiras experiências de residência, bem como registrando sua evolução até os dias atuais em programas de caráter multiprofissional. Observa-se, ao fim e ao cabo, que a formação do psicólogo em programas de residência constitui uma experiência privilegiada, ampliando a sua inserção no setor saúde, em especial no Sistema Único de Saúde. No entanto, este ainda é um tema bastante incipiente, que não é priorizado na literatura mais ampla sobre a formação, carecendo de reflexões educacionais mais sólidas, de aportes teóricos e de estudos empíricos que possam dar conta da complexidade do fenômeno formativo.

Published: October 2018

O presente trabalho possui por objetivo refletir acerca dos elementos que se apresentam no desenvolvimento do sujeito, caracterizando as relações parentais e sua implicação na formação do sujeito. Trata-se de um estudo de revisão de literatura com recortes teóricos psicanalíticos realizados por meio de livros e de textos clássicos da psicanálise, objetivando responder como as relações parentais, em especial o vínculo materno, contribuem para a constituição do sujeito e analisar a relevância de tal vínculo para diagnóstico e a prática clínica psicanalítica. O método empregado neste trabalho foi a pesquisa bibliográfica tendo como vertente a teoria psicanalítica, a qual norteou o trabalho. Os principais autores usados foram Sigmund Freud, Donald Winnicott e Julieta Jerunsalinsky. Este estudo se tornou relevante, pois discorre sobre a dinâmica envolvida na constituição do sujeito relacionando o desenvolvimento com as funções parentais.  Na prática clínica é possível realizar a escuta dos significantes que constituem o sujeito ao longo do desenvolvimento e como consequência proporcionar a ressignificação dos conflitos decorrentes.

Рассмотрены особенности хемостимулирующего воздействия оксидов металлов на процесс термооксидирования полупроводников AIIIBV. Установлено, что химическая природа оксида-хемостимулятора и способ его введения в систему (из газовой фазы или нанесение на поверхность полупроводника) определяют механизм процесса. Оксиды р-металлов (PbO, Sb2O3, Bi2O3) реализуют транзитный механизм оксидирования независимо от способа их введения в систему. Оксиды d-металлов (MnO2, V2O5, CrO3), вводимые через газовую фазу, выступают в роли хемостимуляторов-транзиторов. Воздействие наноразмерных слоев NiO и Co3O4 развивается по транзитному типу. Для нанесённых на поверхность полупроводника наноразмерных слоёв V2O5 механизм их воздействия на процесс оксидирования АIIIВV в значительной мере определяется методом нанесения (в рамках одного способа) – мягким или жёстким.

Aspects of Parenting and the Well-Being of Emerging Adult Language Brokers
Authors: Weisskirch Robert S.
Published: October 2018

The outcomes of language brokering may be shaped by parents and parent–child interactions for language brokers into emerging adulthood. For emerging adults, past parenting may differ by frequency of language brokering and contribute to brokers’ well-being. In this study, 2,473 emerging adults (female = 1,719, male = 746, did not indicate = 8) with two foreign-born parents completed measures of language-brokering frequency, parenting, and well-being. Frequent language brokers reported lower levels of paternal nurturance, paternal connection, maternal nurturance, and maternal connection, and higher levels of maternal disrespect, in comparison to non-brokers. Infrequent language brokers reported lower levels of paternal connection, maternal nurturance, and maternal connection, and higher levels of paternal disrespect, paternal psychological control, maternal disrespect, and maternal psychological control, in comparison to non-brokers. Frequent language brokers indicated higher levels of depressive symptoms in comparison to non-brokers. The combination of frequent language brokering, paternal psychological control, and maternal psychological control were predictive of depressive symptoms. Frequent language brokering, female gender, paternal disrespect, paternal psychological control, and maternal psychological control were predictive of anxiety symptoms. Language brokering did not predict overall psychological well-being.

Published: October 2018

Objective: The purpose of the present study was to evaluate clinically and radiographically the effectiveness of formocresol and the antibiotic paste CTZ (chloramphenicol, tetracycline and zinc oxide-eugenol) in primary teeth pulpotomies, during a 6, 12 and 24 month period. Study design: A total of 80 pulpotomies were performed in 58 patients between three and six years of age. The patients were selected and assigned to two groups: Group I Formocresol (FC, n=40), Group II chloramphenicol-tetracycline-zinc oxide eugenol (CTZ, n=40). The teeth were restored with glass ionomer and pre-formed stainless steel crowns. The treated teeth were evaluated clinically and radiographically at 6, 12 and 24 months. Results: After 24 months of follow up a 100% and 94.3% clinical success was obtained, in the CTZ and formocresol groups respectively (x2= 0.450, p>0.05). The radiographic success was of 97.4% and 94.3% respectively (x2= 0.920, p>0.05). Conclusion: The performance of the antibiotic paste CTZ was superior to formocresol. No statistically significant differences were observed between the treatment groups either clinically or radiographically. More randomized clinical trials should be performed before it can be indicated safely.

Published: October 2018

Objective: This study aimed to assess fluoride intake in infants from formula reconstituted with water, with fluorosis risk in mind. Study Design: Data on water source, formula brand/type, volume of formula consumption and infant weight were collected for infants at two-, four-, six-, nine- and twelve-month pediatrician well child visits. Identified formula brands and water types were reconstituted and analyzed for fluoride concentration. Patient body mass and volume consumed/day were used to estimate fluoride intake from reconstituted formula. Descriptive statistics, one-way analysis of variance and chi-square tests were utilized. Results: All infants consumed formula reconstituted with minimally fluoridated water (0.0– 0.3 ppm). 4.4% of infants exceeded the recommended upper limit (UL) of 0.1mg/kg/day. Although mean daily fluoride consumption significantly differed among all groups, the proportion of infants at each visit milestone that exceeded daily fluoride intake of 0.1mg/kg/day was not statistically significantly different (p>0.05) for any age group. Predicted values calculated with optimally fluoridated water (0.7ppm) resulted in 36.8% of infants exceeding the UL. Conclusions: Optimally fluoridated water may increase fluorosis risk for patients younger than six months. Future investigation should include multiple sites and multi-year follow-up to assess actual fluorosis incidence.

Published: October 2018

Objective: To evaluate the addition of titanium dioxide (TiO2) nanoparticles and cetylpyridinium chloride (CPC) on the compressive strength and antibacterial activity of conventional glass-ionomer cement (GIC). Study design: TiO2 nanoparticles enriched GIC was prepared by adding 3% TiO2 nanoparticles (w/w) into the powder component of conventional GIC. CPC containing GIC was developed by incorporating 1% CPC (w/w) into conventional GIC powder. Samples were segregated into three groups: GIC with 3% TiO2 nanoparticles, GIC with 1% CPC and unmodified conventional GIC. Compressive strength was assessed using the universal testing machine on cylindrical specimens made from each material. Antibacterial activity was assessed by measuring inhibition zones on Mitis Salivarius Bacitracin (MSB) agar inoculated with pure strain of Streptococcus mutans (S. mutans). Results: GIC containing TiO2 nanoparticles exhibited significantly greater compressive strength as compared with CPC and conventional GIC groups (P < 0.01). However, there was no significant difference between the compressive strengths of CPC and conventional GIC group (P >0.05). Antibacterial activity was significantly greater for TiO2 group than conventional GIC (P <0.05). CPC increased the antibacterial activity of conventional GIC, though not significantly. Conclusion: The addition of 3% TiO2 nanoparticles improves the compressive strength of GIC as well as its antibacterial activity against S. mutans.

Published: October 2018

Decades of scholarship have established that dissident activity provokes state repression when it threatens elite interests and legitimacy, but there has been research attention on how state repression diffuses through institutional channels such as courts. Legal settings operate as a key site for the construction and implementation of elite discursive strategies used to undercut the legitimacy of protesters and justify repression. Social movement research on repression and social control often glosses over these elite framing strategies, limiting our understanding of relationship between elite meaning work and repression. We address these gaps in the literature by examining the state's framing of a worker revolt against a 1953 currency reform in communist Czechoslovakia. Drawing on extensive archival materials, we analyze how the regime framed the event and how official frames influenced the legal repression of protest participants. Our research has important implications for understanding the relationship between legal repression and state cultural work.

No Brasil, o ensino da matemática tem apresentado grandes déficits nas avaliações nacionais e internacionais. As possíveis causas disso são: a dificuldade de interpretação por parte dos alunos na resolução de situações-problema, a falta de contextualização e o nível abstrativo de alguns assuntos. Uma das estratégias para a melhoria das notas e do aprendizado matemático que tem surtido efeito em países da Europa e nos Estados Unidos é a interação com os jogos digitais. Para tanto, o objetivo deste artigo é discutir as contribuições dos jogos digitais para o ensino da matemática, como também apresentar o perfil das produções brasileiras para esse fim. Como conclusão, é possível destacar que este campo de pesquisa já vem atraindo adeptos e que as pesquisas têm apontado o potencial dos jogos digitais no que diz respeito ao engajamento, motivação e envolvimento dos estudantes permitindo através disso, a melhoria das notas daqueles que interagem com os jogos digitais.

O presente texto se insere no campo das discussões sobre a formação inicial de professores. De forma específica, objetiva discutir a constituição da docência, problematizando os processos formativos que as Universidades, através dos cursos de licenciatura, vêm desenvolvendo junto à Educação Básica, a partir das políticas públicas de indução à docência. Considerando as inquietações que a formação docente tem nos provocado e os resultados de pesquisa realizada nesse campo, estabelecemos um diálogo com a literatura da área e, a partir do confronto e problematização das ideias, sistematizamos as discussões as quais constituem o corpo deste texto. Inicialmente, destacamos os dilemas da formação de professores, dando ênfase à clássica questão da relação entre teoria e prática, e como esse debate exerce influência na constituição dos saberes e na produção da profissão docente. Em seguida, trazemos algumas reflexões contemporâneas acerca do currículo que forma o professor na licenciatura. Por fim, analisamos as contribuições do Programa Institucional de Bolsas de Iniciação à Docência (Pibid) na constituição do ser professor e no fortalecimento dos vínculos entre Universidade e Educação Básica. Acreditamos que este trabalho pode contribuir e ampliar o debate sobre o tema, nos diversos espaços formativos, na medida em que concebe a constituição da docência na sociedade contemporânea como um processo dinâmico e contínuo. Para tanto, deve considerar o sujeito e suas experiências, singulares e plurais, como protagonista nesta rede de relações que se tecem entre a Universidade e a Escola Básica.
Ensinar, aprender e avaliar como processos integrados na produção de saberes numa aula orientada pela Metodologia de Resolução de Problemas
Authors: Lima Louise , Cosme Ariana
Published: October 2018

Assumimos que ensinar, aprender e avaliar são três processos integrados que devem ocorrer simultaneamente durante a produção de saberes numa aula orientada pela Metodologia de EnsinoAprendizagemAvaliação através da Resolução de Problemas (Metodologia). Nesta orientação pedagógica, o problema é o ponto inicial para se ensinar e um veículo para a aprendizagem e, por isso, há o reconhecimento e a valorização pelo processo de aprendizagem dos alunos e não somente pelos produtos obtidos, estimulando o seu envolvimento e participação ativa neste percurso. A aprendizagem ocorre por descoberta, por meio da interação entre pares e é fomentada pelo trabalho nas comunidades de aprendizagem. A avaliação possui caráter formativo, (re)orientando práticas docentes e discentes. Neste estudo, partilhamos um recorte das reflexões realizadas no desenvolvimento de uma tese de doutoramento. A revisão bibliográfica teve em conta a vasta literatura relativa às teorias da aprendizagem e avaliação, já que o objetivo deste artigo é situar os pressupostos teóricos desta Metodologia, com sua devida articulação e estabelecer a relação entre a intervenção educativa dos professores e o processo de aprendizagem dos alunos. Assim, pretendemos: a)Justificar a necessidade de uma metodologia alternativa, baseado na premência de uma mudança de paradigma educacional; b) Argumentar sobre a necessidade da integração “Ensino-Aprendizagem-Avaliação”; c) Discutir os significados que o termo “Resolução de Problemas” pode assumir; d) Contribuir para um aprofundamento teórico a partir da articulação das teorias de aprendizagem e da avaliação com o trabalho desenvolvido por meio desta proposta metodológica; e) Apresentar um roteiro de orientação para o trabalho pedagógico em uma aula assente na Metodologia. Esperamos que, por meio da apresentação aqui realizada, os que se interessem pelo tema possuam maior esclarecimento, de maneira que sua prática beneficie os reais sujeitos de toda a ação educativa: os alunos.

A formal approach for the verification of the permission-based security model of Android
Authors: Luna Carlos , Betarte Gustavo , Campo Juan , Sanz Camila , Cristiá Maximiliano , Gorostiaga Felipe
Published: October 2018

This article reports on our experiences in applying formal methods to verify the security mechanisms of Android. We have developed a comprehensive formal specification of Android's permission model, which has been used to state and prove properties that establish expected behavior of the procedures that enforce the defined access control policy. We are also interested in providing guarantees concerning actual implementations of the mechanisms. Therefore we are following a verification approach that combines the use of idealized models, on which fundamental properties are formally verified, with testing of actual implementations using lightweight model-based techniques. We describe the formalized model, present security properties that have been proved using the Coq proof assistant and propose the use of a certified algorithm for performing verification activities such as monitoring of actual implementations of the platform and also as a testing oracle.
The “Code Yourself!” and “¡A Programar!” programming MOOC for teenagers: Reflecting on one and a half years of experience
Authors: Friss de Kereki Inés , Paulós J. Víctor , Manataki Areti
Published: October 2018

Critical thinking and problem solving are fundamental skills to function successfully in today’s world. When programming, these skills are promoted, developed and deployed. In this context, Universidad ORT Uruguay and The University of Edinburgh co-created in 2015 a MOOC (Massive Open Online Course) that teaches young teenagers how to program. The course was offered simultaneously in two versions: in Spanish, called "¡A Programar!" and in English, called "Code Yourself!", which are available on the Coursera platform. Since its launch in March 2015, more than 161,000 people from 197 countries have registered. Initially it was offered in a "fixed session"; while currently it is offered in an "auto-cohort" mode. In both cases, student surveys indicate that the course has met or exceeded expectations (values above 93%). In this paper, we detail the characteristics of the MOOC, and we analyze and compare the results for the two delivery modes.
