Published: April 2023

ABSTRACT Objective: To analyze the sociodemographic profile of adolescents working in Brazil and the association of child labor with risk and protection factors for Chronic Noncommunicable Diseases. Methods: Cross-sectional study with data from sample 2 of the 2015 National School Health Survey (PeNSE). The variables gender, age, ethnicity/skin color, administrative dependence on school and maternal education, eating habits, physical activity and drug use were analyzed by prevalence and respective 95% confidence intervals (95%CI) and calculation of crude and adjusted Odds Ratio. Results: A total of 10,926 students participated in the survey, of which 16.9% (95%CI 15.1–18.9) were currently working/employed. Child labor was higher among male adolescents (ORa: 1.82; 95%CI 1.55–2.15); aged between 16 and 17 years (ORa: 2.96; 95%CI 2.37–3.69); enrolled in public schools (ORa: 1.69; 95%CI 1.14–2.52); whose mothers had incomplete high school (ORa: 1.54; 95%CI 1.11–2.13); living in the South region of the country (ORa: 2.17; 95%CI 1.60–2.94). Adolescents who worked were more likely to smoke (ORa: 1.94; 95%CI 1.52–2.48); use alcohol (ORa: 2.01; 95%CI 1.71–2.36) and drugs (ORa: 1.76; 95%CI 1.35–2.31); perform physical activity (ORa: 1.24; 95%CI 1.07–1.44); consume sweets (ORa: 1.30; 95%CI 1.13–1.49), fried snacks (ORa: 1.41; 95%CI 1.15–1.74), and soft drinks (ORa: 1.23; 95%CI 1.06–1.44); however, they were less likely to present sedentary behavior (ORa: 0.68; 95%CI 0.59–0.79). Conclusion: Child labor in Brazil is related to sociodemographic differences. Those who worked were more likely to show risk behaviors for NCDs, but they were more physically active.

Authors: Dulcich Federico
Published: April 2023

Abstract This paper investigates the potential effects of the Mercosur-EU agreement for the automotive value chains in Argentina and Brazil, identifying the trade balance movements of each partner. Its main results point to an improved trade balance in most automotive and auto parts products for the EU. Besides differences in international competitiveness, other factors prompt these results, such as differences in production scale between partners, greater tariff preferences granted by Mercosur, greater potential demand for vehicles in Argentina and Brazil than in the EU, higher regulation requirements on product and process quality in the EU market, among others.

Authors: Souza Caroline Miranda Alves de , Hasenclever Lia , Paranhos Julia
Published: April 2023

Resumo O objetivo deste artigo é analisar o papel da concorrência nos mercados relevantes (MR) selecionados e sua influência no diferencial de preços entre medicamentos genéricos e de referência. Trata-se de um estudo de caso sobre 268 apresentações comerciais de medicamentos, classificados em MR em 2001 e 2016. Os dados para obtenção do grau de concentração foram provenientes da base de dados utilizada por Hasenclever (2002) e do Anuário Estatístico do Mercado Farmacêutico de 2016. Os preços praticados em 2019 foram retirados de dez sites de farmácias e drogarias. Os resultados indicam que a margem de 35% sob o preço do medicamento de referência imposta ao preço-fábrica para a entrada do genérico no mercado é baixa em relação ao diferencial de preços médios praticados no varejo. Além disso, notou-se que, quanto maior o número de fornecedores, maior tendia a ser o diferencial de preços entre medicamentos genéricos e de referência.

Published: April 2023

Resumo O objetivo deste artigo é analisar o impacto da obesidade adulta de homens e mulheres no mercado de trabalho brasileiro e nos rendimentos salariais. A base teórica corresponde ao modelo de Grossman e são utilizados os microdados da Pesquisa Nacional de Saúde (PNS) de 2013. Como metodologia, são usados os modelos Probit e Heckit e o método Propensity Score Matching (PSM). Evidenciou-se associação negativa entre obesidade e a participação no mercado de trabalho e nos salários apenas para as mulheres. Considerando os resultados do PSM, houve a confirmação que ser obeso exerce impacto negativo para as mulheres participarem desse mercado e buscarem maiores rendimentos, já para os homens, esse efeito é positivo. Ações mais efetivas de prevenção à obesidade adulta e redução na desigualdade de gênero devem ser adotadas, pois essa doença crônica gera ônus socioeconômico, especialmente, para trabalhadores do sexo feminino.
TEORIA DA RELEVÂNCIA E TEORIA DA LITERATURA: AS TEORIAS CIENTÍFICAS E AS TEORIAS CRÍTICAS DEVEM SER (RE)CONCILIADAS?
Authors: Bueno Rodrigo , Saussure Louis de
Published: April 2023

Resumo No programa da relevância, Wilson (2012; 2018; 2019) tem conduzido o estudo literário expondo duas conflitantes concepções. A primeira é a concepção dos teóricos relevantistas de que a relevância contribui para o estudo da literatura. A segunda concepção é um contraponto da teoria da literatura, especificada no nome do crítico literário Keith Green (1997), de que a relevância não contribui para o estudo literário. Analisamos ambos os pontos de vista, tais como protagonizados por Wilson e Green, e discutimos a natureza das teorias da linguagem e das teorias da literatura. Propomos que, embora compartilhem o mesmo objeto observacional, isto é, a literatura, a teoria da relevância e a teoria da literatura não compartilham o mesmo objeto teórico, sendo um equívoco a equivalência de ambas. De tal equívoco resulta um problema de incomensurabilidade teórica e um risco eminente de fracasso da pragmática em sua iniciativa de sistematização dos fenômenos literários.
O realismo performático reflexivo no romance latino-americano contemporâneo: a autoria feminina além do “teto todo seu”
Authors: Felippe Renata de
Published: April 2023

Resumo Com base nos romances Temporada de huracanes (2017), da escritora mexicana Fernanda Melchor, e Enterre seus mortos (2018), de Ana Paula Maia, este artigo pretende refletir sobre a incidência e as conotações assumidas pelo realismo performático reflexivo — denominado por Ravetti (2019) como “paradigma Bolaño” —, nos romances latino-americanos contemporâneos de autoria feminina. Nas narrativas de Melchor (2017) e Maia (2018), a violência hiperbólica e a sobreposição/seriação de brutalidades direcionam para uma melancolia de futuro de dimensões antiépicas, traços reiteradamente presentes nos romances latino-americanos contemporâneos. Voltados à tendência apontada, os romances das autoras mexicana e brasileira revelam perspectivas críticas que são erigidas de temas e de abordagens distanciados tanto do “teto todo seu” (Woolf, 2014) quanto das facilidades de um realismo codificado e de pretensões didáticas. Refletir sobre as escolhas autorais responsáveis por esses deslocamentos, bem como sobre a possibilidade de as referidas estratégias acrescerem mais uma nuança às manifestações romanescas recentes, está entre as questões abordadas neste texto.

ABSTRACT Purpose To analyze the effects of lingual frenotomy on the breastfeeding of infants, based on the electrical activity of the masseter and suprahyoid muscles and assessment of the breastfeeding. Methods Observational study developed between October 2017 and June 2018 with a sample of 20 newborns and infants who attended a dental clinic and were diagnosed with ankyloglossia. Another 20 were excluded for meeting some of the following exclusion criteria: babies more than 6 months old, who were not on exclusive or mixed breastfeeding, who had other clinical impairments that interfered with breastfeeding, who had other foods introduced into their diet, who had neurological changes and/or craniofacial deformities, and/or who did not finish all the stages of the study. Breastfeeding was assessed with the UNICEF Breastfeeding Assessment and Observation Protocol, while the muscle electrical activity was assessed with the Electrical Activity Assessment Protocol for the Masseter and Suprahyoid Muscles in Newborns During Breastfeeding. The same speech-language-hearing therapist conducted the two assessments both before the conventional frenotomy and 7 days after it. Results The signs suggestive of breastfeeding difficulties changed 7 days after the surgery, with a p-value ≤ 0.002 for general observation of the mother, position of the infant, latch, and sucking. The maximum voluntary contraction of the masseter was the only integral parameter with a difference, as the electrical activity had decreased. Conclusion Behaviors favorable to breastfeeding increased 7 days after the frenotomy in all the breastfeeding assessment categories, whereas the electrical activity of the masseter decreased.

Abstract Introduction The effects of virtualization on the learning of higher education students are still uncertain, during the year 2022 face-to-face activities returned and others remained in the online format. The latter is the subject of this study. Objective To identify the scope and challenges of synchronous virtual tutorials, carried out in the post-pandemic period, based on the experience and the opinion of occupational therapy professors, and students from a Chilean university. Methodology A mixed methodology is used; information is produced through a focus group with 11 professors and through a questionnaire answered by 76 students. Analysis of the thematic content of the qualitative data and descriptive statistics of the quantitative data is carried out. For the integration of the information produced, data triangulation is used. Results Synchronous virtual tutorials are useful for the acquisition of various types of learning such as the ability to articulate theory with practice. They are space that favors emotional support, offers mutual support to students, and allows the development of social thinking, reflection, and situated. Simultaneously, the findings show the preference by the students for individual learning over the need to produce learning and knowledge collaboratively in post-pandemic times. Conclusions It is suggested to have a significant number and variety of methodologies in synchronous virtual tutorials and that these consider the contexts in which professional practice is carried out.

Authors: Cheng Jingning , Lyu Yong , Cheng Ziyan
Published: April 2023

The early detection of head and neck squamous cell carcinoma (HNSCC) has an important impact on the clinical prognosis. N6-methyladenosine (m6A) is involved in the post-transcriptional regulation of tumorigenesis and development. In this study, the prognosis and biological functions of m6A regulator targets in HNSCC were explored. RNA-Seq expression data and clinical information from TCGA-HNSCC and GSE23036 datasets were collected. The mRNA levels of IGF2BP2 and IGF2BP3 in tumor tissues were significantly up-regulated. Differential expression and functional enrichment analysis of potential targets for IGF2BP2 and IGF2BP3 obtained from the m6A2Target database showed that they were significantly enriched in cell cycle-related pathways. The Cox regression analysis was performed to establish a three-mRNA signature including PLAU, LPIN1 and AURKA. The prognostic effect was verified in the external dataset GSE41613. Further studies revealed that the three-mRNA signature was significantly associated with survival in the clinical subgroup. The ROC curve, Harrell consistency index and decision curve comparison used to compare the predictive effect of the three-mRNA signature and the other signatures in previous studies showed that the three-mRNA signature had better predictive effect on the prognosis of HNSCC patients. The three-mRNA signature expression were verified in HNSCC cell lines with qRT-PCR and Western blot. Sequence analysis showed that m6A-modification sites existed on PLAU, LPIN1 and AURKA genes. In conclusion, the three-mRNA signature has been proved to be useful on evaluating the prognosis and contributing to the personalized treatment of HNSCC, and IGB2BP2/3 were related to the cell cycle in HNSCC.
Analysis of the relationship between the L-box test and the yield stress of fresh concrete: an analytical approach
Authors: Sassi Raoudha , Jelidi Ahmed , Montassar Sami
Published: April 2023

The objective of this work was to study fresh concrete flow in the L-box test, predict the final deposit shape after flow stoppage and estimate the yield stress. This is very useful for controlling concrete casting in real structures, detecting problems and developing solutions on time. Concrete rheometers used for measuring the rheological parameters of concrete are expensive, not always available and can lead to measurement disparity. To overcome these issues, an effective method is to analyse concrete flow phenomena physically and solve the problem analytically based on L-box measurements. In the first part of this work, fresh concrete was considered as a homogeneous yield stress fluid moving under the effect of its self-weight. By developing momentum equations for an incompressible fluid, a theoretical approach was used to study three probable final shapes depending on the concrete rheology. Expressions were established for predicting the final shape and the yield stress. In the second part, the results obtained were compared with those of previous models and good agreement was found, thus validating the proposed approach. This study provides a consolidation of rheometer results, allowing evaluation and perhaps a calibration to reinforce their validity.
Amplitude-frequency response of a helically-wound fiber distributed acoustic sensor (DAS)
Authors: Chugaev A. V. , Tarantin M. V.
Published: April 2023

The goals of this study were to analyze the capabilities of DAS (distributed sensors) in resolving mining problems, compare them with existing seismoacoustic data collection systems, and prepare the basis for conducting seismoacoustic studies with recording by a fiber optic distributed system. This paper considers the capabilities of recording seismoacoustic responses using fiber optic distributed acoustic systems (DAS). Based on physical and geometrical analysis, the amplitude-frequency responses (characteristics) of recorded longitudinal waves for straight and helically-wound fibers were obtained. In the case of helically-wound fiber, the frequency response depends on several key factors: integrating the measured value along the fiber based on the measurement; the angle of incidence on the cable; and the winding angle of the fiber in the cable. An increase in the winding angle increases the uniformity of the amplitude-frequency characteristics of longitudinal waves both in terms of frequencies and angles of incidence. At the same time, helical winding changes the effective response spacing (gauge length). This makes it possible, by summing the responses of the straight and helically-wound fibers due to the overlap of the spectra, to record frequencies that are suppressed in case of separate recording. Based on the study results, a cable design was proposed to record broadband seismoacoustic responses enabling a wide range of mining and engineering problems to be resolved, and for seismic surveys both in wells and on the surface to be carried out.
Study of gas hazard pattern in underground workings after blasting

Published: April 2023

Determining the sources of hazardous and toxic substances released into mine air, their gas composition, as well as providing each such source of pollution with the required amount of fresh air are important issues in terms of ensuring normal healthy and safe working conditions for miners. This paper studies blasting as one of the most dangerous sources of mine air pollution. The study was carried out for a long dead-end exploration working, and a development (preparatory) working of a copper-nickel mine. In accordance with the federal rules and regulations (FNiP), a number of requirements, including monitoring of gas hazard at a face, is applied to blasting operations.

The study examined the behavior of gas-air mixture in dead-end mine workings after blasting. The findings are based on the experimental data obtained in the conditions of two dead-end workings at an operating coppernickel mine. A technique for the experimental studies of gas release after blasting in a dead-end working was developed. The main technical characteristics of the instruments involved in the in-situ measurements are given. Time dependences of the concentrations of toxic gases after blasting at the blasted working mouth,   at the return ventilation current, and near a booster were established. In order to assess the reliability of the data obtained, the volume of released carbon oxides was calculated based on the data of gas analyzers and chemical reactions of explosives decomposition during detonation, depending on the types and weights of the explosives. A model of gas-air mixture transfer was described, constructed, and calibrated allowing for longitudinal dispersion. The Voronin model was used to simulate the gradual removal of toxic gases from the working face and solving the problem of boundary conditions. Based on experimental data, the coefficients of longitudinal dispersion, ventilation efficiency, and volume concentration of the considered gas admixture in the mixing zone at initial time were determined for a long dead-end mine working.

The constructed gas-dynamic model and longitudinal dispersion coefficients obtained as a result of the analysis enabled the time required for long dead-end mine workings ventilation to be analysed and estimated. Based on the model, the algorithm for calculating the velocity of spreading the combustion products in a mine ventilation network in emergency situations is being improved. The value of longitudinal dispersion coefficient for different operating conditions is also being refined.

Based on the gas distribution simulation within the interval of 1,500 m from a working face, the time required for the ventilation of a dead-end mine working was determined.
Behaviour pattern of rock mass haulage energy intensity in deep pits
Authors: Zhuravlev A. G. , Glebov I. A. , Chernykh V. V.
Published: April 2023

A significant portion of mineral deposits developed by open-pit mining is opened to the full depth by road transport ramps without the use of combined transport. In most cases, this is dictated by the high rate of a pit deepening and multi-stage development. In this study, the energy intensity of rock mass (RoM) haulage from the working zone of a pit to the surface is considered at several hierarchical levels. Mineframe software was used to study 3D-models of open pits with different slope angles in order to test the method of analytical calculation of a pit volume that allowed ensuring accuracy under a wide range of mining conditions. The findings of the research are as follows: with an increase in the pit bottom diameter, the zone of stabilization of rock mass lifting (haulage) height shifts to greater target depths. An increase in the pit slope angles entails shifting the weighted average height to deeper elevations. By increasing the pit target depth, combined modes of transport become more economical in comparison with dump trucks due to an increase in the total volume of rock mass. Depending on the comparison purpose, it was proposed    to use different types of energy intensity. For a broad estimation of the rationality of the pair “scheme of opening – mode of transport” for open pits, the ratio of potential energy intensities of rock mass haulage   of a considered option of a pit opening and its basic option without transport berms was used. The ratio of potential energy intensities as a function of a pit depth was determined. The values of total energy intensity of rock mass haulage from a pit to the surface were also established.
Equivalent circuit for mine power distribution systems for the analysis of insulation leakage current
Authors: Pichuev A. V. , Petrov V. L.
Published: April 2023

Successful mining businesses rely heavily on the safety and reliability of their mine power distribution systems. Mine power distribution systems are designed to withstand an aggressive environment with a range of hazards. The harsh operating conditions require improvement to personnel protection systems through the study and simulation of the electric network’s normal and emergency operations. The purpose of this study is to assess insulation leakage current using an equivalent circuit of a mine power distribution system. The simulation identified the key properties of the equivalent circuit which can model potential hazardous situations. We also selected the quantitative metrics and the equivalent circuit property ranges. In order to simulate the transients, we recommended using the time constants for the oscillation damping in circuits, the insulation phase resistance properties, and the absorption currents. This paper presents the equations to estimate these values. As an example, we considered the equivalent circuit of a mine power distribution system with an R-L filter in the residual current device line. The equivalent circuit helps analyze the current leakage when a person touches a live phase conductor accounting for low-frequency polarization in the phase insulation. The proposed approach to the simulation and analysis of the insulation current makes it possible to generate an equivalent circuit of the mine power distribution system to analyze phase voltage asymmetry, trip currents of residual current devices, low-frequency polarization of the insulation, and the leakage current effects on the human body.
El sector turístico en el contexto de transición energética
Authors: Flensborg Karen Ivana
Published: April 2023

La transición hacia un aprovisionamiento energético más sostenible adquiere relevancia frente a un escenario climático crítico. Desde la década de los 70 del siglo pasado, se evidencia una preocupación entre los académicos, los Estados y las organizaciones no gubernamentales acerca de la necesidad de disminuir el uso de fuentes fósiles y las emisiones de gases de efecto invernadero (GEI) asociadas a este. El sector turístico no queda exento de esos retos, por tal motivo, en el presente trabajo se propone como objetivo analizar la situación del turismo en el contexto de transición energética, en pos de identificar los desafíos que se presentan para su descarbonización. El estudio, de carácter exploratorio-descriptivo, se apoya en fuentes secundarias de información provenientes de bibliografía especializada, documentos estadísticos y normativos. Los resultados arrojan que los estudios académicos-científicos se han incrementado paulatinamente en los últimos años, y se detectan desafíos socioculturales, económico-financieros, político-normativos, técnicos y ambientales, a los que cada uno de los componentes del sector turístico debe enfrentarse para una transición hacia una economía baja en carbono. No obstante, resulta necesario profundizar los análisis desde enfoques holísticos que aborden críticamente la apropiación energética en el sector turístico.
ISP Research Proposal v1
Authors: Garibay Erica
Published: April 2023

The island of Mo’orea is the heart of French Polynesia’s pineapple production. Ever since farmers advocated for the opening of the Rotui Juice Factory in 1981, production has increased to support growing demand for the factory’s tropical fruit juices. Today, pineapple (Ananas comosus) persists as the primary cash crop, accounting for 140 hectares of the island’s agricultural land (PROTEGE, 2021). Pineapple cultivation on Mo’orea is concentrated in the slopes of ‘Opunohu Valley where pineapple producers generally follow conventional agricultural production methods, such as monocropping, application of toxic synthetic fertilizers and pesticides, and tilling. In fact, pineapple plantations score lowest for soil health among crop production systems surveyed throughout French Polynesia (Surchat et al., 2021). Conventional methods notoriously cause soil compaction, decreased water infiltration, decreased soil microbiomes, decreased soil organic matter, decreased biodiversity, and leave large areas of land without living cover for extensive periods, leading the topsoil to become critically vulnerable to erosion. On pineapple farms, one study identified the bare access corridors and roads between fields as the most at-risk sites for erosion (Binnet & Gonnot, 2005). In addition, researchers estimated soil loss in recently cleared fields to be 400 T/ha/year (Gonnot et Binet, 2004). Notably, the island experiences periods of heavy precipitation that exacerbate on-farm soil erosion. Sediment runoff from the fields contributes to the estimated 388.5 /sediment/day that feed into the ‘Opunohu Bay from the ‘Opunohu River (Taiarui et al., 2017). Erosion control is crucial for ‘Opunohu Bay because sedimentation becomes another stressor for Mo’orea’s reefs. Multiple studies demonstrate that increased sedimentation and turbidity negatively impact coral health and lead to decreased biodiversity in the fringing reef (Morancy, 1994). Sediment smothers corals and decreases light availability for symbiotic algae, thus reducing photosynthetic efficiency (Fabricius, 2005; Tuttle & Donahue, 2022). Corals also experience decreased gamete fertilization, reduced larval settlement, decreased growth rate, and mortality.The impacts of agricultural erosion on marine life should be a concern for local authorities and could be mitigated by decreasing the amount of exposed soils (Boutillier & Duane 2006). If conventional production methods also degrade marine ecosystems then: How can incorporating agroecology-based farming principles into the Opunohu Valley’s pineapple producing-sites benefit coral reef management and conservation in Mo’orea, French Polynesia?

CagA phosphorylation assay and its semiquantitative analysis v1
Authors: F. Zeitler Anna
Published: April 2023

CagA is the oncogenic toxic of Helicobacter pylori. The toxin is injected into host cells and tyrosine phosphorylated in the C-terminal EPIYA motifs by host kinases. Positive translocation of the CagA toxin into the cell is evaluated by detecting the phosphorylated form in the cell lysate using antibodies detecting phosphotyrosines. Previously detection was limited to a positive o negative results, but with new advances in semiquantitative western blots we are able to quantify changes on CagA translocation / Phosphorylation and get a better idea of the dynamics of injection. The protocol described here has been used for evaluation of CagA phosphorylation and its semiquantitative analysis in the following publications: DOI:10.1111/cmi.12166; DOI:10.1038/srep23227, and DOI:10.1016/j.mimet.2016.04.016

Published: April 2023

Objective. To analyze the literature relating to qualitative research about the theme family that was published in Brazilian nursing journals in the period from 2006 to 2010.

Methodology. Research involving investigation of bibliographic databases of articles presenting descriptors like the following terms: family, qualitative research and nursing.

Results. 47 articles were analyzed. The most frequent topic areas are: child health (40.4%), adult health (23.4%), mental health (19.1%), collective health (6.4%), elderly health (6.4%) and woman’s health (4.3%). 70.6% of the articles were published in journals classified by QUALIS/ CAPES as B1. 93.6% of the articles were written by nurses with a doctorate degree. Data collection was predominantly carried out using semistructured (57.4%) and open interviews (39.8%). The interviews were followed by observation methods in 8.5% of the analyzed studies.

Conclusion. The literature about qualitative studies that address the theme family which was published in Brazilian nursing journals during the study period is rare, which shows the need to further address the topic.

The nurse teacher. Construction of a new professional identity.
Authors: Aguayo Gonzalez Mariela Patricia , Monereo Carles
Published: April 2023

Objective. To represent how a new identity is being constructed by nurses initiating their activities as teachers.

Methodology. In 2010, a descriptive-interpretative qualitative research was conducted of four cases of nurse teachers from Nursing Schools. Aspects of teacher identity and management of critical incidents in the classroom were reviewed. The information was obtained through a structured survey and the data underwent analysis of contents.

Results. The nurses surveyed state that the teaching exercise is a culmination stage of clinical nursing. Teaching confers them stability in their professional life; however, they report that the complexity of the educational practice poses a big challenge. They feel responsible for the formation of future nursing professionals. In spite of defining themselves as constructivists in the way of teaching, they are governed by a technical conception on the way of approaching the educational practice. They attribute the critical incidents to which they are exposed to the types of students entering the universities; these turn out uncomfortable and do not feel responsible for their development. These incidents are lessons to better face similar situations in the future.

Conclusion. The nurses participating in this study are facing their new role as teachers of human resource, seeking to construct a new identity different from what they had when working in direct care of individuals.

Attention to every detail makes part of the nurse’s world in their care actions. They are responsible for everything in the service and it implies “having to have four eyes”.

Conclusion: the nurses’ world, in the studied services, is characterized as a complex context that demands to be permanently attentive to multiple and simultaneous situations. In their own words is defined as “Here we never rest”.
