Authors: Santos Wellington da Silva , Santos Michelli Ferreira dos , Costa Marcones Ferreira 
Published: April 2020

RESUMO: No Brasil o livro didático foi regulamentado com a legislação criada em 1938 pelo decreto de lei 1006. Os livros didáticos passaram a ser utilizados cada vez mais e para garantir a distribuição em escolas públicas e a qualidade deste material o governo federal criou o Programa Nacional do Livro Didático (PNLD) através do decreto de n° 91.542/85. Atualmente, este programa é responsável pela importância que o livro didático tem para o sistema educacional brasileiro. Os livros das editoras inscritos no PNLD chegam até as escolas e os professores são os responsáveis por realizar as escolhas e isso acontece a cada três anos. Esse trabalho apresenta um estudo sobre a escolha e o uso dos livros didáticos de ciências por professores do ensino fundamental de escolas públicas do Município de Caridade do Piauí. Foram entrevistados 20 professores de ciências das maiores escolas públicas de ensino fundamental do município. Os professores foram questionados sobre como acontece o processo de escolha dos livros nas escolas onde trabalham, se tiveram acesso ao Guia dos Livros Didáticos durante a escolha e que critérios utilizaram para tomar suas decisões. O estudo averiguou a interferência da internet na utilização dos livros. Através desta pesquisa observou-se que os professores não seguem a risca as orientações do PNLD para a escolha dos livros, pois as escolas só começam a se movimentar para tomar decisões após a chegada dos livros enviados pelas editoras e os docentes não dispõem de tempo necessário para fazerem uma boa escolha. A maioria revelou que não utilizaram ou não tiveram acesso ao Guia do Livro Didático para selecionar os livros com os quais trabalham. A maior parte dos professores revela que escolhem o material didático baseados em critérios estabelecidos por eles mesmos. Apesar de não seguirem as instruções do PNLD para a escolha, os atuais livros de ciências trabalhados nas escolas foram bem avaliados pelos professores em vários critérios como o conteúdo teórico, os recursos visuais, as atividades propostas e os recursos adicionais. Sobre a interferência da internet na utilização do livro didático, a maior parte dos professores afirma que os livros continuam sendo o principal material utilizado em sala de aula e consideram que a internet funciona como uma ferramenta de apoio ao livro didático.

Published: April 2020

Background and PurposeThe Health Risk Screening Tool (HRST) is a 22-item instrument specifically designed to assess the health risk of persons with developmental disabilities. The predictive validity of the HRST was investigated by examining its ability to predict mortality.MethodsThe sample consisted of 12,582 people with an intellectual or developmental disability residing in Georgia (U.S.). Data were analyzed using survival analysis (Kaplan–Meier estimate and Cox regression) and a binary logistic regression.ResultsAll models supported the prognostic value of the six-level health risk classification. The Kaplan–Meier procedure showed clear separation among functions. The Cox proportional hazard regression revealed that hazard is inversely related to the health risk level, even after controlling for potential confounding by gender, ethnicity, and race.ConclusionsThe HRST can predict mortality. Therefore, it can serve as a basis for establishing healthcare needs and determining nursing care acuity.

Published: April 2020

Objectives. To quantify the number of people in the US who delay medical care annually because of lack of available transportation and to examine the differential prevalence of this barrier for adults across sociodemographic characteristics and patient populations. Methods. We used data from the National Health Interview Survey (1997–2017) to examine this barrier over time and across groups. We used joinpoint regression analysis to identify significant changes in trends and multivariate analysis to examine correlates of this barrier for the year 2017. Results. In 2017, 5.8 million persons in the United States (1.8%) delayed medical care because they did not have transportation. The proportion reporting transportation barriers increased between 2003 and 2009 with no significant trends before or after this window within our study period. We found that Hispanic people, those living below the poverty threshold, Medicaid recipients, and people with a functional limitation had greater odds of reporting a transportation barrier after we controlled for other sociodemographic and health characteristics. Conclusions. Transportation barriers to health care have a disproportionate impact on individuals who are poor and who have chronic conditions. Our study documents a significant problem in access to health care during a time of rapidly changing transportation technology.

<em>Low seeds quality of the clove tree may attribute to the low national productivity of cloves in Indonesia. The study aimed to determine the level of physiological fruit maturity and the effect of germination media on the viability of clove seeds. The study was performed at the Leuwikopo Seeds Storage and Quality Testing Laboratory and Leuwikopo Research Installation, Bogor, in October 2017 to December 2018. The material used was the Zanzibar clove seeds from ≥ 10 years old trees. The clove seeds obtained from a farmer’s plantation in Tolitoli District, Central Sulawesi. The study arranged in a split-plot design, with four replications, with the main plot was four levels of seed viability based on fruit colors: reddish-green, pink, red, and dark red. The subplots were three types of germination media, namely sand, cocopeat, and zeolite. Thus, there were twelve treatments. Each plot consisted of 40 seeds for germination test and five seeds for water content determination. The results showed that the percentage of clove seeds viability negatively influenced by the level of fruit maturity based on the color of the fruit but was affected by the germination media. Good physiological quality of clove seeds characterized by dry seed weight of 2.70 g, 100 % germination rate, vigor index of <em>73.75 %, and growth rate of 1.19 % etmal<sup>-1</sup>. Among the three types of germination media tested (sand, cocopeat, and zeolite), sand was the best germination media for clove seeds. Hence it is recommended to seeds producer.</em></em>
Developing Load Balancing for IoT - Cloud Computing Based on Advanced Firefly and Weighted Round Robin Algorithms
Authors: Et al. Abed 
Published: April 2020

The evolution of the Internet of things (IoT) led to connect billions of heterogeneous physical devices together to improve the quality of human life by collecting data from their environment. However, there is a need to store huge data in big storage and high computational capabilities. Cloud computing can be used to store big data. The data of IoT devices is transferred using two types of protocols: Message Queuing Telemetry Transport (MQTT) and Hypertext Transfer Protocol (HTTP). This paper aims to make a high performance and more reliable system through efficient use of resources. Thus, load balancing in cloud computing is used to dynamically distribute the workload across nodes to avoid overloading any individual resource, by combining two types of algorithms: dynamic algorithm (adaptive firefly) and static algorithm (weighted round robin). The results show improvement in resource utilization, increased productivity, and reduced response time.

Summary
Understanding the effect of typical water-related improved oil recovery techniques is fundamental to the development of chalk reservoirs on the Norwegian Continental Shelf (NCS). We investigate the contribution and interplay of key parameters influencing the reservoir's flow and storativity properties, such as effective stresses, injecting fluid chemistry, and geomechanical deformation. This is done by developing a mathematical model that is applied to systematically interpret experimental data. The gained understanding is useful for improved prediction of permeability development during field life.
The model we present is for a fractured chalk core whereby fluids can flow through the matrix and fracture domains in parallel. The core is subject to a constant effective stress above the yield, resulting in time-dependent compaction (creep) of the matrix, while the fracture does not compact. Reactive brine injection causes enhanced compaction but also permeability alteration. This again causes a redistribution of injected flow between the two domains.
A previous version of the model parameterizing the relation between chemistry and compaction is here extended to quantify the effect on permeability and see the effect of flow in a fracture-matrix geometry. A vast set of experimental data were used to quantify the relations in the model and demonstrate its usefulness to interpret experimental data. Two outcrop chalk types (Aalborg and Liège) being tested at 130°C and various concentrations of Ca-Mg-Na-Cl brines are considered. However, assumptions were required, especially regarding the fracture behavior because directly representative data were not available.
The tests with inert injecting brine were used to quantify the effect of matrix and fracture mechanical compaction on permeability trends. To be able to explain the tests with reactive brine, an important finding is that permeability not only decreased because of enhanced porosity reduction but also because of a quantifiable chemistry-related process (dissolution/precipitation).
Sensitivity analyses were performed regarding varying fracture width, injection rate, and chemistry concentration to evaluate the effect on chemical creep compaction and permeability evolution in fractured cores. The model can be used to highlight parameters with great influence on the experimental results. An accurate quantification of such parameters will contribute to refining laboratory experiments and will provide valuable data for upscaling and field application.

Abstract
Background Since the inception of newborn screening programs in China in the 1990s, pregnancy among patients with inherited, metabolic disorders has become more common. This study explores the management and outcomes of planned, full-term pregnancies in patients with phenylketonuria (PKU).Method Married patients with PKU from 2012 to 2017 were enrolled to receive prenatal counseling and regular health assessments. Study-related assessments included the timing of Phe-restricted diets, maternal weight gain, gestational age, pregnancy complications, and blood Phe concentrations (both pre-conception and during pregnancy), obstetrical data, and offspring outcomes(e.g. anthropomorphic measurements and developmental quotients [DQs]).Results A total of six offspring were successfully delivered. The mean±SD (range) age of the mother at delivery was 26.3±4.7 (range: 21.1-32.5) years. The mean duration of Phe control before pregnancy was 5.5±1.3(range: 3.1-6.5) months. During pregnancy, the proportion of blood Phe concentrations within the clinically-recommended target range (120–360μmol/L) ranged from 63.2-83.5%. Low birth weight (<2500g) offspring occurred in two women who experienced suboptimal metabolic control. In addition, offspring DQ was related to the proportion of blood Phe levels per trimester that were within the recommended range (r=0.886, p=0.016).Conclusion This is the first report of women in China with PKU who successfully gave birth to clinically healthy babies. Infant outcomes were related to maternal blood Phe management prior to and during pregnancy. In maternal PKU patients with poor compliance to dietary treatment, sapropterin dihydrochloride（6R-BH4）may be an option to improve the management of blood Phe levels.
Moderation effect of emotion regulation on the relationship between social anxiety, drinking motives and alcohol related problems among university students
Authors: Kim Sojung , Kwon Jung-Hye 
Published: April 2020

Abstract
Background: Accumulated evidence suggests that individuals with social anxiety disorder (SAD) are at particular risk of developing alcohol use disorder (AUD). Yet, little is known about the mechanisms under this high comorbidity. This study aimed to elucidate the process of the development of alcohol related problems among individuals with elevated social anxiety. We investigated the moderation effect of difficulties in emotion regulation on the relationship between symptoms of social anxiety, coping and conformity motives and alcohol related problems. Methods: In a sample of university students (N = 647) in South Korea, we examined whether cognitive (fear of negative evaluation), behavioral (social avoidance), and physiological symptoms (concerns over physiological symptoms) of social anxiety affect alcohol related problems with the mediation of coping and conformity motives. Furthermore, difficulties in emotion regulation were hypothesized to moderate each mediational path. Results: Results showed that the fear of negative evaluation and concerns over physiological symptoms were associated with alcohol related problems with the mediation of conformity and coping motives, respectively. As hypothesized, each path was moderated by difficulties in emotion regulation. Conclusions: Findings suggest that coping and conformity motives to cope with cognitive and physiological symptoms of social anxiety were related to alcohol related problems. In addition, individuals with high levels of difficulties in emotion regulation were prone to exhibit more alcohol related problems.
The Association between Sleep Quality and Loneliness in Rural Older Individuals: A Cross-Sectional Study in Shandong Province, China.
Authors: Jia Gaizhen , Yuan Ping 
Published: April 2020

Abstract

Background: There is a evidence of negative association between loneliness and sleep quality in older adults. However, little is known regarding the relationship between loneliness and sleep quality among Chinese rural older adults. This study examined the associations of loneliness and sleep quality in a cross-sectional study of older adults. Methods: A face-to-face questionnaire survey was conducted among 1658 rural older adults in Shandong Province, China. Loneliness was assessed using the University of California at Los Angeles Loneliness Scale. Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Ordinal logistic regression was conducted to examine the association of loneliness and sleep quality after adjustment for multiple confounding variables. Results: After variables such as age, marriage, education, occupation, economic income, family relationships, living arrangement, smoking behavior, alcohol consumption, chronic disease experience, and quality of life were controlled in a multivariable analysis, poor sleep quality was still associated with loneliness in the rural older population. Conclusion: This finding implied an adverse effect of sleep quality on the loneliness of older adults. Poor sleep quality was associated with increased odds of loneliness in Chinese rural older adults. Sleep-based interventions should be developed to prevent loneliness in rural older adults in China.

Abstract
Background: Sugira Muryango ​ is a father-engaged early child development and violence-prevention home-visiting programme delivered by trained lay workers. This cluster-randomised trial evaluates whether families living in extreme poverty ( Ubudehe 1, the poorest category in the Government of Rwanda’s wealth ranking) who receive Sugira Muryango in combination with a government-provided social protection programme demonstrate greater responsive, positive caregiving, nutrition, care seeking, hygiene, and father involvement compared with control families receiving usual care (UC). Methods: Using detailed maps, we grouped closely spaced villages into 284 geographic clusters stratified by the type of social protection programs operating in the village clusters; 198 clusters met all enrolment criteria. Sugira Muryango was delivered to n=541 families in 100 treatment clusters with children aged 6–36 months living in extreme poverty. We assessed changes in outcomes in intervention and 508 UC control families using structured surveys and observation. Analyses were intent to treat using mixed models to accommodate the clustering. Results: Families receiving Sugira Muryango improved on core outcomes of parent-child relationships assessed using the Home Observation for Measurement of the Environment (Cohen’s d =0.87, 95% CI: 0.74, 0.99) and the Observation of Mother-Child Interaction (Cohen’s d =0.29, 95% CI: 0.17, 0.41). We also saw reductions in harsh discipline on items from the UNICEF MICS (OR=0.30: 95% CI: 0.22, 0.51) and violent victimization of female caregivers by their partners (OR=0.49, 95% CI: 0.24, 1.00) compared with UC. Moreover, children in families receiving SM had a 0.45 higher increase in food groups consumed in the past 24 hours (Cohen’s d =0.35, 95% CI: 0.22, 0.47), increased care seeking for diarrhoea (OR=4.43, 95% CI: 1.95, 10.10) and fever (OR=3.28, 95% CI: 1.82, 5.89), and improved hygiene behaviours such as proper treatment of water (OR=3.39, 95% CI: 2.16, 3.69) compared with UC. Finally, Sugira Muryango was associated with decreased caregiver depression and anxiety (OR=0.58, 95% CI: 0.38, 0.88). Conclusions: Sugira Muryango led to improvements in caregiver behaviours linked to child development and health as well as reductions in violence.
