MULTIMODALIDADE EM IMPRESSO PARA A EDUCAÇÃO EM SAÚDE: ANÁLISE DE UM COMPONENTE DA CAMPANHA “#MOSQUITONÃO”
Authors: Costa Jefferson Silva , Carneiro-Leão Ana Maria Dos Anjos
Published: December 2021

As campanhas sanitárias objetivam sensibilizar a população para o cuidado com a saúde, desta forma, esse tipo material encontra-se imerso no âmbito da Educação em Saúde, tendo o professor como agente mediador em potencial. Portanto, é imperativo pesquisar a respeito dos impressos que compõem as campanhas sanitárias, considerando-os como multimodais, uma vez que aglutinam diversos modos semióticos em sua composição, carecendo de uma metodologia de análise que possibilite essa compreensão. A partir disso, este trabalho objetivou analisar um texto multimodal da campanha “#MosquitoNão” considerando seu uso educacional. A análise foi realizada a partir das funções linguístico-semióticas da Gramática do Design Visual, que proporcionou a compreensão do todo composto pela interação verbal-visual. A análise do impresso possibilitou enxergar algumas problemáticas em sua construção: transferência de responsabilidade sobre o combate do Aedes aegypti para a população, demarcando uma omissão do sujeito produtor (Governo Federal Brasileiro) ; estratégias de convencimento pautadas no medo ao invés de construir o argumento em torno de conceitos biológicos, como o de ciclo de vida, podendo dificultar a compreensão do sujeito leitor interativo do porque é importante proceder a eliminação dos potenciais criadouros do mosquito a cada sete dias; necessidade inerente de que o material seja complementado durante seu uso. Todas essas problemáticas abrem margem para a construção de um diálogo mais aprofundado a respeito da necessidade de oportunizar letramentos multimodais para educadores em saúde, visto que apenas com profissionais aptos a ler textos multimodais é que será possível a este educador observar suas lacunas para então preenche-las.

Authors: Santos Gisele Abreu Lira Corrêa dos , Rezende Filho Luiz Augusto Coimbra de , Mello Rodrigo Vasconcelos Machado de
Published: December 2021

Este trabalho teve por objetivo investigar por meio da noção de reendereçamento de audiovisuais, o uso que uma professora de Química fez do filme Erin Brockovich. O seu plano de aula com o uso do filme associado a materiais intertextuais visava promover a aprendizagem de conceitos químicos e o debate de questões socioambientais orientadas para uma conexão com o recente crime ambiental em Brumadinho. Esta etapa da pesquisa foi desenvolvida a partir de uma entrevista semiestruturada com a professora e a observação da utilização do filme em uma turma de ensino médio profissionalizante para jovens e adultos. Foi possível notar que o reendereçamento a partir de um filme de entretenimento construído pela professora foi capaz de direcionar os sentidos produzidos pelos estudantes para os atuais problemas do país.
Self-evaluation and observation: A proposal to promote CLIL teacher training at Infant Education
Authors: Custodio Espinar Magdalena , Gómez Cortés José Antonio
Published: December 2021

The Bilingual Program of the Community of Madrid (BPCM), Spain, started offering Content and Language Integrated Learning (CLIL), in English, at Primary Education in 2004, at Secondary in 2010, and at Infant Education (3–6-year-old students) in 2017. This approach requires multiskilled practitioners, highly trained in the CLIL methodological principles, to ensure the planning and delivery of effective lessons. However, CLIL teacher training is deficient and needs to be boosted through alternative proposals. This work analyses the potential of a checklist for self-evaluation and observation of CLIL teachers at Infant Education. It is an exploratory research that presents a case study in two Infant Education classrooms in which CLIL is taught by the same teacher. The data collection includes linguistic data collecting techniques such as the checklist for the observer and for the teacher, an observation protocol, transcripts of the interviews, among others. Results from the qualitative analysis of the Infant teacher self-evaluation and the observer showed that a never-ending-teacher-development-awareness to promote teachers to manage their experience adequately was stimulated, and it was likely to open the door to innovation in educational trends (CLIL) in order to offer a solid respond for their professional needs. It also proved to identify the actual CLIL training needs of the Infant teacher and unveiled her thoughts and practice in her bilingual classes. Therefore, it can be concluded that the self-evaluation checklist can be a useful instrument likely to shed some light on the complex phenomenon of in-service CLIL teacher training.
Opiniones acerca de los procesos de autoevaluación con fines de acreditación: La mirada de las Comisiones de Autoevaluación de la Escuela de Ciencias de la Educación de la Universidad Estatal a Distancia, Costa Rica.
Authors: Hidalgo Chinchilla Rosa María , Ocampo Hernández Christian , Rivera Sánchez Yarith , Salas González Silvia
Published: December 2021

Las Comisiones de Autoevaluación (CAE) tienen un papel protagónico en el desarrollo de los procesos de autoevaluación, con fines de acreditación, que llevan a cabo las carreras de grado y de posgrado de la Escuela de Ciencias de la Educación (ECE), que cuentan con la acreditación otorgada por el Sistema Nacional de Acreditación de la Educación Superior (SINAES) de Costa Rica; de modo que para evidenciar ese protagonismo se investigaron las opiniones de las personas que las conforman, en lo referente a la metodología de trabajo, la participación y la comunicación y las competencias y la capacitación de esas comisiones. La opción metodológica seleccionada para describir las opiniones fue de naturaleza cuantitativa, para ello se empleó un cuestionario. Los resultados reflejan una percepción positiva hacia la razón de ser y el impacto de los procesos de autoevaluación, en el afán de conseguir la acreditación. Se evidencian ligeras diferencias en las opiniones, en relación con la metodología; si bien, las personas consideran confiables y válidos los métodos, las técnicas y los recursos empleados en la recolección de información; también cuestionan su carácter totalmente cuantitativo y limitante con respecto a la participación de las personas protagonistas, como ocurre en el caso del profesorado y del estudiantado. Además, argumentan que la metodología se ajusta poco al contexto de UNED. En lo relacionado con la participación y comunicación que se genera; así como con las competencias y la capacitación de las CAE, se muestran resultados que evidencian aspectos que también requieren atenderse.
A study on the effect of process parameters on the joint strength and leak tightness in electromagnetically assisted adhesive Cu-SS tube-to-tube joining through statistical analysis
Authors: Kumar Deepak , Kore Sachin D , Nandy Arup
Published: December 2021

This work studies an improved hybrid joining technique combining
electromagnetic forming and adhesive joining to create a leak-tight
Cu-SS tube-to-tube joint named as electromagnetically assisted adhesive
joining (EAAJ). An experimental investigation is performed considering
three discharge energy (3.9 kJ, 4.4 kJ and 5.0 kJ), four adhesive
application lengths (20 mm, 15 mm, 10 mm and 5 mm), three adhesives
(Loctite 638, Loctite 567, and Loctite SI 596) and four curing times (24
hours, 48 hours, 96 hours and 120 hours) as process parameters. The
mechanical properties of the joints are investigated using testing
techniques like pull-out, compression, and micro-hardness tests. An
increase in joint strength is observed with the decrease in adhesive
application length and increase in curing time. Maximum joint strength,
90% of the base copper tube strength, is obtained in the case of
Loctite 638, with 5 mm of adhesive application length, 5.0 kJ of
discharge energy and 96 hours of curing time. Furthermore, a three-way
analysis (3-way ANOVA) of variance technique is implemented to calculate
the contribution of the three factors (discharge energy, adhesive
application length, type of adhesives) on the joint strength. A cohesive
and adhesive failure mode combination leading to sliding failure mode is
observed as a joint failure mechanism during pull-out and compression
testing. A leak testing setup has been developed to investigate the
joint’s leak tightness by an air pressure decay test. An increment in
leak tightness by 1000 times is observed in 638 EAAJ samples compared to
samples joined without adhesives. A 3-way ANOVA analysis is also
performed to calculate the contribution of different factors on leak
tightness of the joint. Micro-hardness is observed to be increased near
the joint interface compared to the base metal. Deformation analysis has
highlighted the impact of field shaper slit causing a non-uniformity in
radial deformation in the circumferential direction and leading to
non-uniform circumferential accumulation of adhesive.
Are Outcomes in Congenital Cardiac Surgery Better Than Ever?
Authors: Holcomb Ryan , Ündar Akif
Published: December 2021

Background and Aim of the Study: Congenital heart disease is
the most common congenital defect among infants born in the United
States. Within the first year of life, 1 in 4 of these infants will need
surgery. Only one generation removed from an overall mortality of 14%,
many changes have been introduced into the field. Have these changes
measurably improved outcomes? Methods: The literature search
was conducted through PubMed MEDLINE and Google Scholar from inception
to October 31, 2021. Ultimately, 78 publications were chosen for
inclusion. Results: The outcome of overall mortality has
experienced continuous improvements in the modern era of the specialty
despite the performance of more technically demanding surgeries on
patients with complex comorbidities. This modality does not account for
case-mix, however. In turn, clinical outcomes have not been consistent
from center to center. Furthermore, variation in practice between
institutions has also been documented. A recurring theme in the
literature is a movement towards standardization and universalization.
Examples include mortality risk-stratification that has allowed direct
comparison of outcomes between programs and improved definitions of
morbidities which provide an enhanced framework for diagnosis and
management. Conclusions: Overall mortality is now below 3%,
which suggests that more patients are surviving their interventions than
in any previous era in congenital cardiac surgery. Focus has
transitioned from survival to improving the quality of life in the
survivors by decreasing the incidence of morbidity and associated
long-term effects. With the transformation towards standardization and
interinstitutional collaboration, future advancements are expected.

Authors: García Federico , Serrano-Conde Esther , Leyva Alba , Fuentes-Lopez Ana , Salazar Adolfo de , Chueca Natalia , Castro Sonia Pérez , Regueiro Benito , Rojas Almudena , Mendoza Joaquín , Rojas Jose
Published: December 2021

Background: SARS-CoV-2 variation represents a serious challenge
to current COVID-19 vaccines. Recent reports suggest that B.1.351 and
other variants may escape the neutralization activity of the antibodies
generated by current vaccines. Methods: Ninety-nine healthcare
workers undertaking BNT162b2 mRNA vaccination were sampled at baseline,
on the day of the second dose, and 14 days after the latter.
Neutralization activity against SARS-CoV-2 B.1, B.1.1.7 and B.1.351 was
investigated using a Vero-E6 model. Results: Eleven of the
study participants had prior infection with SARS-CoV-2. Neutralization
titers against the B.1 and the B.1.1.7 variants were not statistically
different and were significantly higher than titers against the B.1.351
variant across pre-exposed and non-pre-exposed vaccinated individuals (
p<0.01). While all vaccinated individuals presented
neutralizing antibodies against B.1 and B 1.1.7 after the second dose,
14% were negative against B.1.351, and 76% had low titers (1/20-1/80).
Pre-exposed vaccinated individuals showed higher titers than
non-pre-exposed after the first (median titers of 1/387 versus 1/28,
respectively) and the second doses (1/995 versus 1/703, respectively).
As high as 72% of the pre-exposed vaccinees presented titers
>1/80 after a single dose, while only 11% of non-exposed
vaccinated individuals had titers >1/80.
Conclusions: BNT162b2 mRNA-induced antibodies show a lower in
vitro neutralizing activity against B.1.351 variant compared to
neutralization against B.1.1.7 or B.1 variants. Interestingly, for
individuals pre-exposed to SARS-CoV-2, one dose of BNT162b2 mRNA may be
adequate to produce neutralizing antibodies against B.1.1.7 and B.1,
while two doses of BNT162b2 mRNA provide optimal neutralizing antibody
response against B.1.351 too.

Claude Levi-Strauss and the myth Anamorphoses
Authors: Silva Gustavo Ruiz da , Werneck Mariza Martins Furquim
Published: December 2021

The article intends to demonstrate that, when building his science, Claude Lévi-Strauss abandons the categories used by the traditional studies of the myth and creates singular epistemological tools, suggested by the music, by the natural science and by the plastic arts. These tools, which we can denominate aesthetic operators, light up, in exemplary way, the dissolution process that suffers the mythical matter when transforming in the time and in the space. When establishing that new form of thinking, the myth, that reconciles the sensitive experience with the intelligible, Lévi-Strauss proposes to overcome the permanent dichotomy between knowing archaic and modern, between magical and scientific thought, between magic and Science.
Dinoflagellate cysts from the Pannonian (late Miocene) "white marls" in Pécs-Danitzpuszta, southern Hungary
Authors: Krizmanić Krešimir , Sebe Krisztina , Magyar Imre
Published: December 2021

Dinoflagellate-cyst based biostratigraphy is an important tool in the stratigraphical subdivision and correlation of the Neogene Lake Pannon deposits. A total of 66 palynological samples were investigated from the Pannonian (upper Miocene) marl succession exposed in the Pécs-Danitzpuszta sand pit in order to evaluate the biostratigraphical assignment and constrain the age of the strata. Earlier attempts to recover dinoflagellate cysts from this important reference section had failed. In our material, six samples contained well-preserved palynomorphs. One sample from the lower part of the succession (D25) contained a probably reworked middle Miocene assemblage. Samples from the middle segment of the succession (D3, D2, D1) indicate the Pontiadinium pecsvaradensis Zone (ca. 10.8 to 10.6 Ma). Samples from the top of the marl (D219, D221) did not give additional stratigraphic information (P. pecsvaradensis Zone or younger). The palynofacies of samples D3 to D221 indicates a relatively distal, calm, occasionally oxygen-deficient, probably deep depositional environment.
Middle Miocene (Badenian) macroinvertebrates from Pécs-Danitzpuszta (Mecsek Mts, SW Hungary)
Authors: Dulai Alfréd , Henn Tamás , Sebe Krisztina
Published: December 2021

This paper examines Badenian (middle Miocene) macroinvertebrates – corals and molluscs – from the Pécs-Danitzpuszta sand pit (Mecsek Mts, SW Hungary) in order to extend our knowledge on Miocene normal marine deposits of the Mecsek region. Corals occur reworked in the upper Miocene sand that was deposited in the brackish Lake Pannon, and presumably originate either from the middle Badenian Pécsszabolcs or the upper Badenian Rákos Member of the Lajta Formation. A total of seven taxa were identified. These taxa suggest subtropical conditions and a lack of coral reefs in the Badenian. Molluscs were found in situ in the upper Badenian Szilágy Clay Marl Member of the Baden Formation and the Rákos Member of the Lajta Formation. They dominantly consist of bivalves and represent benthic assemblages typical of the middle Miocene Central Paratethys.

Published: December 2021

Introduction. The effectiveness of the actions of the fire protection units depends on their readiness for action, that is, on the state of the forces and means of the station and the ability to perform the main task within the existing tactical capabilities.
Problem Statement. When developing mathematical models of the operational activities of the fire department, its effectiveness and the assessment of the readiness of fire protection units to extinguish fires, it is important to study the dependence of the death of people in fires on the duration of the fire. This study is devoted to this task.
Theoretical Part. The distribution of fires in the Russian Federation for 2016-2020 by their duration and the dependence of deaths and injuries of people in fires, as well as their ratio to the duration of fires in the Russian Federation for 2016-2020, is studied. It is shown that the average duration of the fire during the studied period was 26 minutes, the median value of the distribution was 18 minutes. The dependences of deaths and injuries of people in fires on the duration of fires are approximated by a logarithmic function. When the duration of the fire is up to 26 minutes. the ratio of the number of people injured in fires to those killed decreases exponentially, but remains stable in the rest of the time range.
Conclusions. It is concluded that it is necessary to increase the readiness of the fire department for actions to extinguish fires and rescue people, which includes the development of an information and analytical model of the operational activities of the fire department.

Published: December 2021

Introduction. The paper presents the results of the studies on assessing the quality of the aquatic ecosystem of a lake located within the city. The European perch (Perca fluviatilis L.) and the Gibel carp (Carassius gibelio) were used as an indicator for determining the quality of the aquatic ecosystem by the method of fluctuating asymmetry.
Problem Statement. The aim of the work was to conduct monitoring with the subsequent assessment of the quality of the ecosystem of the city lake using the method of fluctuating asymmetry (hereinafter FA).
Theoretical and Practical Part. The quality of the urban lake aquatic ecosystem was assessed using the FA method (indicators: the European perch (Perca fluviatilis L.), 1758 and the Gibel carp (Carassius auratus Bloch), 1783). To identify the reasons for the high PFA values, a chemical analysis (in an accredited laboratory) of the gills of the Gibel carp for heavy metals was performed.
Conclusions. As a result of the research, the FA indicators values for these indicators were obtained. According to the results of a laboratory study of the content of heavy metals in the gill arches of the Gibel carp, an excess of the maximum permissible concentration of 8 out of 10 analyzed elements was revealed. It has been established that the ecosystem of the city lake Kenon is experiencing a significant anthropogenic load (5 points — the critical quality of the aquatic environment) and it continues to increase towards the deterioration of the habitat.

Authors: Munthali Nyamwaya , Lie Rico , Van Lammeren Ron , Van Paassen Annemarie , Asare Richard , Leeuwis Cees
Published: December 2021

Information and communication technologies (ICTs), specifically those that are digital and interactive, present opportunities for enhanced intermediation between actors in Ghana’s agricultural extension system. To understand these opportunities, this study investigates the capabilities of ICTs in support of seven forms of intermediation in the context of agricultural extension: disseminating (information), retrieving (information), harvesting (information), matching (actors to services), networking (among actors), coordinating (actors), and co-creating (among actors). The study identifies the types of ICTs currently functioning in Ghana’s agricultural system, and applies a Delphi-inspired research design to determine the consensus and dissensus of researchers, scientists, and practitioners about the potential of these ICTs to support each of the seven intermediation capabilities. The findings reveal that experts reached consensus that interactive voice response (IVR) technologies currently have the highest potential to support disseminating, retrieving, harvesting, and matching. Meanwhile, social media messaging (SMM) technologies are currently seen as highly capable of supporting coordinating and, to a lesser extent, co-creating, but no consensus is reached on the potential of any of the technologies to support networking.

Türkiye dünya çam balı üretiminde lider konumdadır. Çam balının özünü ise, çam ağaçlarına konuk olan basra böceği (Marchalina hellenica Genn.) oluşturmaktadır. Basra böceği konuk olduğu ağacın bitki özsuyu ile beslenmekte, ihtiyacı olan besini aldıktan sonra geri kalan kısmını ise rektal yolla dışarı bırakmaktadır. ‘Bal özü’ adı verilen bu salgı, daha sonra arılar tarafından toplanarak bala dönüştürülmektedir. Elde edilen bu salgı balı ise ‘çam balı’ olarak adlandırılmaktadır. İbreli ağaçlar içerdikleri bazı ekstraktif maddeler nedeniyle böcekler için cezbedici ya da uzaklaştırıcı etkiye sahip olabilmektedir. Basra böceği ile konukçuları arasında böyle bir ilişkinin belirlenmesi üzerine literatürde bazı çalışmalar mevcuttur. Bu çalışmada, basra böceğinin konuk olduğu ibreli ağaçların ekstraktif maddeleri olan ilişkisi incelenmiş ve literatür bilgileriyle Muğla ormanlarındaki benzer durumlar karşılaştırmalı olarak değerlendirilmiştir.
