FEATURE FILMS AS A SOURCE OF SOCIOCULTURAL KNOWLEDGE ABOUT GERMANY
Authors: Савина Ольга Юрьевна 
Published: October 2022

В настоящее время цифровые технологии позволяют активно использовать в образовательном процессе самые разные визуальные средства. Однако, как показывает опыт, преподаватели иностранных языков довольно редко включают просмотр кинолент в процесс обучения. Цель настоящего исследования заключалась в описании роли художественных фильмов в формировании социокультурной компетенции и определении их места в процессе обучения немецкому языку. Для достижения указанной цели были проанализированы актуальные исследования о фильмах как средстве формирования социокультурной компетенции. Анализ показал, что они могут служить не только средством повышения мотивации, но и богатейшим источником социокультурных знаний, зачастую компенсируя информационные пробелы в учебниках. На эмпирическом этапе исследования был проведен опрос среди студентов, изучающих немецкий язык, и выявлены основные тенденции в использовании аутентичных художественных фильмов - студенты мало знакомы с немецким кинематографом, невысоко ценят актуальность фильмов, а преподаватели редко предлагают их к просмотру, ограничиваясь при этом лишь несколькими известными картинами. Таким образом, предположение о весьма скромной роли фильмов в процессе обучения немецкому было подтверждено эмпирически. В заключение даны рекомендации об использовании немецкоязычных художественных кинолент, обладающих богатым дидактическим потенциалом для развития социокультурной компетенции.
Nowadays, digital technology allow to actively use a variety of visual media in an educational process. However, the experience shows that foreign language teachers rather rarely include movies in their lessons. The purpose of this study is to describe the role of feature films in the development of sociocultural competence and to determine their place in teaching German. In order to achieve this goal, we analyzed the current research works on films as a means of development of sociocultural competence. The analysis showed that movies not only increase motivation, but can also be a rich source of sociocultural knowledge that often compensates for information gaps in textbooks. At the empirical stage we made a survey among the students studying German and revealed the main trends in the usage of authentic feature films. Students know little about German cinematography, value low the relevance of films, and teachers rarely offer films for watching, limiting themselves to a few famous films. Thus, our assumption about the very modest role of films in the German learning process was confirmed empirically. We conclude with recommendations for German-language feature films that have rich didactic potential for the development of sociocultural competence.

Abstract
Evidence of disequilibrium chemistry due to vertical mixing in the atmospheres of many T- and Y-dwarfs has been inferred due to enhanced mixing ratios of CO and reduced NH3. Atmospheric models of planets and brown dwarfs typically parameterize this vertical mixing phenomenon with the vertical eddy diffusion coefficient, K

. While K

zz
can perhaps be approximated in the convective regions in the atmosphere with mixing length theory, in radiative regions, the strength of vertical mixing is uncertain by many orders of magnitude. With a new grid of self-consistent 1D model atmospheres from T
eff of 400–1000 K, computed with a new radiative-convective equilibrium python code PICASO 3.0, we aim to assess how molecular abundances and corresponding spectra can be used as a probe of depth-dependent K

zz
. At a given surface gravity, we find nonmonotonic behavior in the CO abundance as a function of T
eff, as chemical abundances are sometimes quenched in either of two potential atmospheric convective zones, or quenched in either of two possible radiative zones. The temperature structure and chemical quenching behavior also change with gravity. We compare our models with available near-infrared and M-band spectroscopy of several T- and Y-dwarfs and assess their atmospheric vertical mixing profiles. We also compare to color–magnitude diagrams and make predictions for James Webb Space Telescope spectra. This work yields new constraints, and points the way to significant future gains, in determining K

Updated Orbit and Observations of Spectroscopic Binary HD 2019
Authors: Fowler Carlie , Pluff John , Thomas Joshua 
Published: October 2022

Abstract
Binary star system HD 2019 was studied by the David Dunlap Observatory between 1935 and 1947. From the spectroscopic data obtained, the orbital elements of the system were defined. Between then and now, there have been no updated studies of this binary star system. We set out to update the orbit of HD 2019 with new spectroscopic data obtained at Clarkson University's Reynolds Observatory. After finding the radial velocities of the star or stars visible in each spectrum, estimates of the error for each measurement were made. From the radial velocities and error estimates, new orbital elements were fit using the data from David Dunlap Observatory combined with the new data collected at Clarkson. These results lead to further investigation of the eccentricity of the orbit. Using the method of Lucy 2005, we ran a test to check the statistical significance of the eccentric orbit using p-value testing.

Este artigo tem como objetivo analisar os indicadores de desenvolvimento do pensamento algébrico manifestados por alunos ingressantes do curso de Licenciatura em Matemática, da Universidade Tecnológica Federal do Paraná, campus Cornélio Procópio, por meio da resolução de problemas. A pesquisa seguiu uma abordagem qualitativa, buscando o entendimento de aspectos relacionados ao desenvolvimento do pensamento algébrico dos participantes. Para a coleta de dados, elaborou-se um instrumento com sete problemas que envolvem conteúdos de Álgebra, o qual foi aplicado em uma turma 37 alunos ingressantes do curso de Licenciatura em Matemática, na disciplina de Fundamentos da Matemática 1. Para contemplar o objetivo enunciado, são apresentados três dos problemas aplicados. A análise dos dados abarcou as resoluções dos participantes, fazendo uma triangulação com o referencial teórico que trata dos indicadores do desenvolvimento do pensamento algébrico. Os resultados apontaram um índice menor do que 50% em cada indicador analisado, o que revela que o pensamento algébrico dos participantes não é satisfatório.
Entre análise de textos e narrativas de professores que ensinam matemática: interesses e primeiros movimentos de pesquisa
Authors: Andrade Mirian Maria 
Published: October 2022

Este artigo apresenta considerações em torno dos meus primeiros movimentos de pesquisa no Programa de Pós-Graduação em Formação Cientifica, Educacional e Tecnológica - PPGFCET. São pesquisas de mestrado, ainda em andamento, que revelam os interesses de pesquisa que tenho exercitado na linha de educação matemática, neste programa. O foco dessas investigações debruça-se sobre dois principais temas: a análise de textos escritos, mobilizando para isso o Referencial Metodológico da Hermenêutica de Profundidade; e a elaboração e análise de narrativas de professores que ensinam matemática em espaços e momentos de formação, por meio da metodologia História Oral. O texto traz esses dois movimentos de pesquisas, chamados aqui de movimentos 1 e 2, e esses cuidam, especificamente e respectivamente, de uma investigação com professores participantes da Oficina Pedagógica de Matemática - OPM, cujas narrativas foram elaboradas a partir de entrevistas parametrizadas pela História Oral e uma investigação das Trilhas de Aprendizagem do estado do Paraná disparando um exercício hermenêutico de análise.

Authors: Lins Heloísa Andreia De Matos , Maluf Júlia Lepre , Freitas Natália Fernanda 
Published: October 2022

Este artigo objetiva apresentar e discutir dois estudos de caso em torno dos direitos das crianças - onde são destacadas as questões de gênero e sexualidade - e o papel fundamental das mídias nesse contexto formativo, num momento de ascensão do ultraconservadorismo no Brasil. Consideradas as especificidades desses estudos cartográficos, foram enfatizados como principais resultados, a partir das contribuições centrais de J. Butler, G. Louro, F. Guattari, M. Foucault e M. Sarmento: 1) a potencialidade das crianças quanto à ressignificação das questões afeitas à diferença (com destaque à parentalidade), 2) manifestações infantis e produções midiáticas que ratificam estereótipos de gênero, 3) no processo atual de regulação das práticas e saberes infantis, observa-se um importante empobrecimento simbólico no processo educativo e na participação política e cidadã das crianças, além dos 4) impactos negativos profundos da formação ultraconservadora sobre a democracia brasileira.

Authors: Adusumilli Devika , Syed Saba , Pattnaik Snigdha 
Published: October 2022

Background:
In the area of adolescent health, there is growing evidence that effective health promotion interventions among adolescents, providing skills and knowledge, may have direct effects on a range of health outcomes. Thus, the study aimed to assess the effect of mixed-method intervention on self-esteem, body image satisfaction, eating disorders among adolescent school students.

Materials and Methods:
The cross-sectional study was conducted among high school students in a metropolitan city. At baseline, self-esteem, perception of body image, and pressure by media of participants were assessed using validated self-reported measures. The mixed-method intervention was a body image enhancement program conducted over 6 weeks through six 45–60 min sessions. Postintervention, participants' scores in the above-mentioned domains were assessed using the same self-reported measures. Data analysis was done using SPSS 23.0, and Fisher's exact test, paired t-test, etc., were applied as appropriate.

Results:
Out of 60 participants, 47% were girls and 53% were boys. Baseline self-esteem scores of girls were lower as compared to boys and were significantly higher in both postintervention. Body image satisfaction among girls improved from 53.57% to 78.57% after intervention. At baseline, higher proportion of girls had likelihood of developing an eating disorder which reduced postintervention.

Conclusions:
The school-based mixed-method intervention was effective in improving self-esteem, body image satisfaction, and reducing the influence of sociocultural attitudes on appearance in adolescent students.

Authors: Ogochukwu Adibe Maxwell , Gloria Anene-Okeke Chigozie , Uchenna Igboeli Nneka , Chibueze Anosike 
Published: October 2022

Background:
The use of drugs by teenagers is a major health concern globally. At this transitional point, secondary school students are the most vulnerable and are susceptible to risks associated with lack of knowledge of substance use.

Objective:
The objective of this study was to evaluate the knowledge, attitude, and practice of substance use among Nsukka secondary school students.

Methods:
This was a cross-sectional study using a validated, self-administered questionnaire, comprising seven sections: demographic characteristics, knowledge of substance use, attitude toward substance use, practice of substance use, contributing factors, effects of substance use, and commonly used substance. Using IBM SPSS Statistics 20, the data were analyzed. To summarize the data, descriptive analysis (frequency, percentage, mean, and standard deviations) was used.

Results:
Over half of the respondents were female (57.5%) and were junior secondary school students (62.2%). Most of the respondents (80%) were conscious of substance abuse. More than half (52.5%) of the respondents had good knowledge of substance usage and only 9.6% of the respondents had a negative attitude toward drug use. It was deduced from the collected data that most students never carried out substance use activities. The respondents agreed that alcohol was the commonly used substance (52.4%) and curiosity (51.7%) was the major contributing factor among school students to substance use.

Conclusion:
The study found that students in secondary schools had sufficient awareness and a constructive outlook toward drug use, and that the majority did not use substance. Among high school students, alcohol was the most commonly used substance.

Published: October 2022

BACKGROUND:
This study aimed to determine the association of single-nucleotide polymorphisms (SNPs) of interleukin-6 (IL-6) gene with the survival and disease status of patients after allogeneic hematopoietic stem cell transplantation.

MATERIALS AND METHODS:
It was a prospective cohort study of total 102 participants, 51 patients along with their donors who had human leukocyte antigen-identical-matched allogeneic hematopoietic stem cell transplantation (aHSCT). Their pretransplant and posttransplant blood samples were collected for extraction of DNA for genotyping by sequence-specific primers polymerase chain reaction and gel electrophoresis followed by sequencing. The pre- and posttransplant levels of IL-6 were measured using enzyme-linked immunosorbent assay technique.

RESULTS:
The mean age of our patients was 19.83 ± 12.5 years having males 65 (63.7%) and females 37 (36.3%). The frequency of −174G/C SNP among acute graft-versus-host disease (aGVHD) group was GG = 53.8%, GC = 34.6%, and CC = 11.5%, and for −597G/A SNP, it was GG = 69.2%, GA = 15.4%, and AA = 15.4%. Our results showed that the presence of G allele in both homozygous and heterozygous forms was associated with increased aGVHD incidence, while the homozygous CC and AA mutant genotypes correlated with the lowest number of cases of aGVHD. The polymorphism −597G/A was significantly associated with the incidence of aGVHD with P = 0.04. The GG genotype in −174G/C and −597G/A was found to be significantly associated with aGVHD with P < 0.0001. High serum levels of IL-6 pre- and posttransplant were found to be significantly associated with the incidence of aGVHD with P < 0.0001.

CONCLUSION:
We concluded that the two SNPs − 174G/C and − 597G/A in the promoter region of IL-6 gene present either in donors or recipients predisposed to increase the risk of development of aGVHD following aHSCT. Their evaluation in our transplant setting may help in the risk stratification of transplant recipients early in time and predict the onset of aGVHD and mortality.

Authors: Alkhamesi Sultan , Almohammadi Abdullah , Alahwal Hatem , Barefah Ahmed , Bahashwan Salem , Radhwi Osman 
Published: October 2022

BACKGROUND:
Many systematic reviews (SRs) and meta-analyses (MAs) have been published regarding the incidence of venous thromboembolism (VTE) in coronavirus disease 2019 (COVID-19) patients, which is acknowledged as high. Therefore, we aimed to assess the methodological quality of any SR/MA involving VTE and COVID-19.

METHODS:
This is a meta-epidemiological study evaluating the methodological quality of SR/MA. A structured search in PubMed and Web of Science was done for all SRs/MAs in VTE and COVID-19 from inception till April 29, 2021. We evaluated the methodological quality using A Measurement Tool to Assess SRs-2 (AMSTAR-2) checklist.

RESULTS:
We included 29 SRs/MAs where only one SR/MA was rated as high (3.44%), 12 (41.37%) were rated as moderate, and the rest were rated as low/critically low (55.17%). No statistical significance was observed in Spearman's correlation analysis between the rate of methodological quality and the number of authors, searching period, publication month, and publishing journal's impact factor.

CONCLUSIONS:
The number of published SRs/MAs in the VTE and COVID-19 subject is rising rapidly. The readers should pay attention to the low methodological quality of most published SRs/MAs.
Twisted algebras of geometric algebras
Authors: Matsuno Masaki 
Published: October 2022

AbstractA twisting system is one of the major tools to study graded algebras; however, it is often difficult to construct a (nonalgebraic) twisting system if a graded algebra is given by generators and relations. In this paper, we show that a twisted algebra of a geometric algebra is determined by a certain automorphism of its point variety. As an application, we classify twisted algebras of three-dimensional geometric Artin–Schelter regular algebras up to graded algebra isomorphism.
Preparation and optimization of glyceryl monooleate-low molecular weight chitosan nanoparticles for delivery of morpholinopyrrolizine derivative
Authors: Elsayed Amani , Belal Amany , Al-Sou’od Khaldoun 
Published: October 2022

Purpose: To develop and optimize glyceryl monooleate–low-molecular-weight chitosan (GMO-LMWC) nanoparticles loaded with morpholinopyrrolizine derivative (NPM).
Methods: Molecular mechanics was used to determine the main driving force for the complexation between glyceryl monooleate (GMO) and chitosan. Nanoparticles were fabricated using a modified film-rehydration method. Optimization was carried out using a statistical design approach. The effects of formulation factors (concentrations of GMO, LMWC and Tween 80) on zeta potential and particle size were investigated using a 23 factorial design.
Results: A steady increase in binding energy was observed when chitosan length was increased from 22 to 142 Å, and thereafter it remained almost constant. The examined independent variables had significant effects on particle size and zeta potential. The particle size of the nanoparticles varied from 265 to 1270 nm while zeta potential was in the range of 3 – 12 mV. The optimized preparation showed a significantly low half-maximal inhibitory concentration (IC50) when compared to a free anticancer agent in the hepatocellular carcinoma (HePG-2) cell line.
Conclusion: A nanoparticulate system composed of GMO and LMWC is a potential nanocarrier for delivery of morpholinopyrrolizine derivative.
