title: Translating Thinking and Statistical Literacy Activities for the Classroom: building an educational product

description: Abstract This study presents the construction of an educational product for teaching and learning of Statistics through discussion of the theoretical foundations that substantiate statistics. It also aims to show notes, which can set up guidelines regarding the conduction of activities by the teacher with a view to greater efficiency when using such didactic and methodological proposition. Such matters comes from a previous literature review and perceptions that emerged during its implementation in a High School Senior class (3rd year of high school) and further analysis that was made in this evaluation test, field research. As part of this construction, its application is exemplified by the activities with students. This entire process is based on a Master's Degree research developed by the Professional Master's Program in Mathematics Education at the Federal University of Ouro Preto.

title: Exposure source prevalence is associated with gender in hepatitis C virus patients from Rio de Janeiro, Brazil

description: BACKGROUND Hepatitis C virus (HCV) infection is a worldwide public health problem. A characterisation of the differences in exposure sources among genders will enable improvements in surveillance actions. METHODS Exposure data were obtained for 1180 confirmed HCV cases Brazil’s mandatory reporting to epidemiological surveillance, which was directed by a reference laboratory in Rio de Janeiro, Brazil. The Chi-square test (χ2) was used to assess the associations between exposure sources and gender. The prevalence ratio (PR) was calculated for exposures that showed an association. RESULTS The results showed 57.7% cases were female, and associations with snorting drugs, sexual activity, surgery, aesthetic procedures, blood transfusions, and educational level were observed (p &lt; 0.001). Men showed 2.53 (1.33-3.57), 4.83 (3.54-6.59), and 2.18 (1.33-3.57) times more exposure to sniffing drugs, risky sex and higher levels of education, respectively, than women. Women demonstrated 4.46 (3.21-6.21), 1.94 (1.43-2.63), and 3.10 (2.09-4.61) times more exposure to surgery, aesthetic procedures, and blood transfusions, respectively, than men. CONCLUSION Our results showed differences in risk behaviours associated with gender among HCV carriers. These data are likely to significantly influence clinical practice regarding the adoption of specific approaches for counselling and control policies to prevent the emergence of new cases and break the chain of transmission of the virus.

title: Ontoprolog: a language to specify discourses on ontologies

description: ABSTRACT This paper introduces the information architecture of a textual formal language to represent and to reason about real problems based on domain ontologies and foundational ontologies. The framework is based on Logic Programming, and consists of a formal language that uses the metamodeling paradigm to produce heterogeneous ontologies that can be described as instances of foundation ontologies.

title: Experimental study on the flexural behavior of large-scale rectangular concrete-filled steel tubular beams

description: ABSTRACT This paper presents a series of test results of large-scale rectangular concrete-filled steel tubular (CFST) beams to explore their performance under pure bending. Concrete-filling tests were initially carried out on two beam specimens of 12-m in length to investigate the feasibility of casting horizontally large-scale rectangular tubes. A total of six 6-m long specimens were subjected to flexural test afterward, including four CFST beams and two steel hollow section (SHS) beams for comparison. The test results showed that the rectangular CFST beams behaved in a relatively ductile manner. The concrete infilling enhanced the flexural behavior and performance of the steel tubes. Finally, the rigid-plastic theory showed suitable to predict the moment capacity of CFST compact beams.

title: Assessment of changes in spine curvatures and the sensations caused in three different types of working seats

description: Abstract Aims This study aimed to evaluate the changes in the spine curvatures and the sensations caused by different types of seats: standard, ischial support and salli. Methods The analyzes were performed by the kinematics and scales of discomfort and pain in 14 healthy subjects. The data collection occurred in three days, one day for each type of seat. The subjects answered questionnaires and were assessed for placement of kinematic markers used to measure the thoracic, thoraco-lumbar and lumbar angles. Each trial was conducted in a sixty-minute period on each chair. Results and conclusions The results showed that the salli seat type causes larger lumbar angles, which is consistent with the maintenance of lumbar lordosis. Likewise, the salli seat showed smaller thoraco-lumbar angle, which is consistent with smaller inferior thoracic kyphosis. Paradoxically, the ischial support seat produced less discomfort and pain than salli type. And finally, the longer the sitting position was the higher the score on the discomfort scale.

title: Thermoplastic Waxy Starch Films Processed by Extrusion and Pressing: Effect of Glycerol and Water Concentration

description: Thermoplastic starch properties depends of plastification process. The aim of this study was to analyze the effect of concentration of glycerol and water on plastification, glass transition temperature (Tg) and tensile properties of thermoplastic waxy starch (TPWS). Formulations were extruded in the following concentrations of starch/glycerol/water: 70/30/0 (TPWS 0%); 70/25/5 (TPWS 5%); 70/20/10 (TPWS 10%) weight percentage. Crystalline peaks in WAXS diagrams and native grains present in SEM micrographs showed that the TPWS 0% and 5% were not sufficient to promote total plastification of the waxy starch, and TPWS 10% showed the higher starch plastification. Tg measurements by DMTA were 30 ºC to TPWS 0%, 23 ºC to TPWS 5% and 40 ºC to TPWS 10%. These results showed that glycerol and water had effect plasticizer in TPWS 5% and antiplasticizer in TPWS 10%. Mechanical tensile results showed that higher tensile strength was observed in the systems with more effective starch plastification.

title: Emergence of methicillin-resistant Staphylococcus aureus from clonal complex 398 with no livestock association in Brazil

description: CC398 is a livestock-associated Staphylococcus aureus. However, it has also been isolated from humans with no previous contact with livestock. A surveillance of methicillin-resistant S. aureus colonisation among children attending public day care centres and hospitals in Niterói and Rio de Janeiro, Brazil, between 2011 and 2013, resulted in the isolation of six cases of CC398 from individuals with no previous exposure to livestock. These isolates showed a high frequency of the erm(C) gene (4/6, 66.7%) with induced resistance to clindamycin, and a relatively high frequency of SEs and lukS/lukF genes. These results suggest the emergence of a non-LA-CC398 in Brazil.

title: Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions

description: BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing. METHODS Twenty-five patients with a confirmed diagnosis of CL and ulcerated lesions underwent biopsy of ulcer borders. One direct microbial parameter (germ identification in cultures) and four indirect clinical parameters (secretion, pain, burning sensation, pruritus) were analysed. FINDINGS Biopsies of ten lesions showed secondary infection by one or two microorganisms (Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Streptococcus pyogenes and Candida parapsilosis). “Secretion” and “burning sensation” influenced epithelialisation time but not total healing time. Positive detection of germs in the ulcer border and “pain” and “pruritus” revealed no influence on wound closure. CONCLUSIONS Our borderline proof of clinical CL ulcer infection inhibiting CL wound healing supports the need to follow antimicrobial stewardship in CL ulcer management, which was recently proposed for all chronic wounds.

title: Zero Calcium Score as a Filter for Further Testing in Patients Admitted to the Coronary Care Unit with Chest Pain

description: Abstract Background: The accuracy of zero coronary calcium score as a filter in patients with chest pain has been demonstrated at the emergency room and outpatient clinics, populations with low prevalence of coronary artery disease (CAD). Objective: To test the gatekeeping role of zero calcium score in patients with chest pain admitted to the coronary care unit (CCU), where the pretest probability of CAD is higher than that of other populations. Methods: Patients underwent computed tomography for calcium scoring, and obstructive CAD was defined by a minimum 70% stenosis on invasive angiography. Results: In 146 patients studied, the prevalence of CAD was 41%. A zero calcium score was present in 35% of the patients. The sensitivity and specificity of zero calcium score yielded a negative likelihood ratio of 0.16. After logistic regression adjustment for pretest probability, zero calcium score was independently associated with lower odds of CAD (OR = 0.12, 95%CI = 0.04-0.36), increasing the area under the ROC curve of the clinical model from 0.76 to 0.82 (p = 0.006). Zero calcium score provided a net reclassification improvement of 0.20 (p = 0.0018) over the clinical model when using a pretest probability threshold of 10% for discharging without further testing. In patients with pretest probability &lt; 50%, zero calcium score had a negative predictive value of 95% (95%CI = 83%-99%), with a number needed to test of 2.1 for obtaining one additional discharge. Conclusion: Zero calcium score substantially reduces the pretest probability of obstructive CAD in patients admitted to the CCU with acute chest pain.

title: The face of the other: the particular versus the individual

description: Abstract Five interrelated case studies from the sixteenth to the twentieth centuries develop the dynamic contrast between portraiture and pictorial genres newly invented in and about Latin America that do not represent their subjects as individuals despite the descriptive focus on the particular. From Jean de Léry’s genre-defining proto-ethnographic text (1578) about the Tupinamba of Brazil to the treatment of the Creole upper class in New Spain as persons whose individuality deserves to be memorialized in contrast to the Mestizaje, African, and Indian underclass objectified as types deserving of scientific study, hierarchical distinctions between portraiture and ethnographic images can be framed in historical terms around the Aristotelian categories of the universal, the individual, and the particular. There are also some intriguing examples that destabilize these inherited distinctions, such as Puerto Rican artist José Campeche’s disturbing and poignant image of a deformed child, Juan Pantaléon Aviles, 1808; and an imaginary portrait of Moctezuma II, c. 1697, based on an ethnographic image, attributed to the leading Mexican painter Antonio Rodriguez. These anomalies serve to focus the study on the hegemonic position accorded to the viewing subject as actually precarious and unstable, always ripe for reinterpretation at the receiving end of European culture.
