Trabajo Social con familias en el contexto mexicano. Definiciones y aproximaciones metodológicas desde la práctica
Authors: Mancinas Espinoza Sandra E. , Rodríguez Otero Luis Manuel
Published: April 2024

En México, la política sobre familia se inscribe en un régimen de bienestar conservadorfamiliarizado, y en este los trabajadores sociales son actores claves para ejecutar dicha política. Son estos quienes a menudo se ubican en los espacio de entrada en el sistema de bienestar social, situándolos en las contradicciones del mismo (Banks, 1997). Además, las políticas neoliberales(Montaño, 2014) y el expertise teórico metodológico de los trabajadores sociales (Mancinas, 2016) hacen de la práctica un proceso sumamente complejo. El objetivo de este artículo es analizar el sustrato teórico-metodológico, que emplean los trabajadores sociales para conceptualizar a las familias y para desarrollar estrategias de intervención con estas. Siguiendo un enfoque deinvestigación cualitativo, se realizaron cuatro grupos de discusión, en los que participaron 29 trabajadores sociales que laboraban en las áreas de salud mental, abusos de sustancias, servicios sociales y educación en el área metropolitana de Monterrey (AMM). Se observó que coexisten dos grandes tendencias en la definición de familias y de las estrategias de intervención para darles soporte profesional: una apegada a los principios más conservadores del régimen de bienestar, y otra que apunta hacia intervenciones más progresistas.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jo Hyeyoung , Han Hyowon
Published: April 2024

Objectives The purpose of this study is to investigate the effectiveness of community-based environmental programs for alternative school children, focusing on environmental behavior, pro-environmental behavior, environmental sensitivity and awareness.
Methods The subjects of the study are 19 students from Alternative School A in Seoul. The trends (M, SD) and normality (Kolmogorov-Smirnov, Shapiro-Wilk) of the pre-post mean scores for the research variables, namely environmental behavior, pro-environmental behavior, environmental sensitivity and awareness, were verified using SPSS 23.0. Since normality was not met, the Wilcoxon test, a non-parametric statistical method that analyzes differences between paired pre- and post-samples, was used to verify effectiveness.
Results The main results are as follows: First, the trend of research variables was analyzed by differentiating between pre-mean scores (a) and post-mean scores (b), and examining the difference (b-a). The results showed improvement in post-mean scores compared to pre-mean scores for all research variables. Second, the normality of the pre- and post-test mean scores of the study variables was not satisfied, so nonparametric statistical methods were used to test for differences. Third, all study variables showed higher post-test mean scores than pre-test mean scores, and the results were statistically significant.
Conclusions The findings of this study suggest that community engagement programs operated by alternative schools should be expanded to support optimized programs by identifying and implementing improvements through continuous monitoring. The proposal focuses on measures for experiential project activities through strengthened collaboration with the local community.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jung Eunkyo
Published: April 2024

Objectives This study aims to develop Satisfaction with Academic Department Scale (SADS) and testing measurement invariance by gender and major field for university students in South Korea.
Methods The survey dataset of 1,775 students was randomly split into two samples. One of them was used for exploratory factor analysis, and the other one was used for confirmatory factor analysis.
Results The results of the exploratory factor analysis indicated that SADS consisted of four factors (i.e.,‘course satisfaction’, ‘relationship satisfaction’, ‘perception satisfaction’, ‘general satisfaction’). The confirmatory factor analysis confirmed that the SADS consisted of 4 factors with 20 items in satisfactory model fit indices. Moreover, measurement invariance by gender and major field (humanities⋅social science/natural sciences⋅engineering/ arts⋅physical education) were strictly supported. The internal consistencies of the items for each sub-factor of SADS were also reliable.
Conclusions It is expected that SADS will be useful instrument to measure the satisfaction with academic department for university students regardless of gender and major field.
Development of content-language integrated learning(CLIL) model with enhanced scaffolding in primary English writing based on coding theme
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Huiwon
Published: April 2024

Objectives CLIL(Content-Language Integrated Learning) is an approach that aims to teach subjects through a foreign language, with the dual purpose of content and language learning (Marsh, 2002). CLIL classes require precise mediation of curriculum objectives, language goals, cognitive goals, and cultural objectives. However, there has been a shortage of practical classroom examples, making it challenging for teachers in the field to implement CLIL effectively. This research proposes an approach to bulid a model to integrate coding content and English in line with the 4Cs framework(Coyle, 2006; Coyle et al., 2010).
Methods Through peer teacher interviews, teacher journals, and student interviews, students' cognitive and language challenges was detected, thus the model incorporated support into the existing 4Cs framework.
Results The support includes providing the native language, multi-modal learning materials, and collaborating. As a result, the 4CS framework with additional scaffolding was presented.
Conclusions This research aims to provide guidelines for CLIL instruction, offering detailed examples of CLIL approaches according to specific topics to facilitate the implementation of content-language integration in real classroom settings.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Seo Jiah
Published: April 2024

Objectives The purpose of this research was to explore effective integrated strategies utilizing Contact Theory principles, to reduce prejudice and discrimination and build friendships between North and South Korean students.
Methods A literature review synthesizing the findings of literature retrieved from searches for integration between North and South Korean students. Especially, Contact Theory was particularly used for the theoretical framework.
Results Intergroup cooperation: Repeated integrated strategies and high-quality contact strategies should be applied in school curriculums to build friendships based on intergroup cooperative tasks such as discussion or presentations about each other’s culture, and societal issues between the two Koreas’ students. Common goals: Both students groups should discuss and debate the common goal of peace within the Korean Peninsula by allowing students to consider the advantages and disadvantages of inter-Korean unification on their own. Equal status: Schools should provide some programmes via literature or films related to North Korean words which are neglected by South Koreans who will need to change their perception by developing a more objective view of North Korean culture and their way of thinking that can ultimately bring equal status between the two Korean student groups. Support of institutions: The support of authorities of the Korean government is suggested. Especially, the government will need to provide more effective teacher education for integrated education between two Korean students to prepare for future reunification.
Conclusions The implications and limitation of the study is provided. Suggestions for future studies are also presented.

Published: April 2024

Green Chemistry is most investigated subject these days. It is also known as sustainable chemistry. Green Chemistry and sustainable chemistry are equals that helps to save and conserve resources. It decreases the effect of chemical products on human and atmospheric health. Green Chemistry gives 12 principles that reduce and prevent the utilization and manufacture of hazardous substance. These principles of green chemistry inform about the various issues related to production of chemical compound. Green Chemistry concept started approximately three decades ago. Green chemistry concept for the chemical synthesis and application launched in 1990. This review article purpose to study about Green chemistry and its application and how green chemistry connect to the phytochemistry.
By establishing Green Aspiration Level (GAL) that is a quantifiable descriptor, process greenness becomes measurable. Green house gases and global warming are the problem that affected the human and environment health. Green chemistry is used in daily life mainly in medicines. Tree bark and Pine bark extracts are mostly used in anti-microbial, antioxidant and anticancer drugs. The matter that present in environment gives applicable things to the researchers and engineers for the changing and developing a sustainable culture. The word “Green chemistry” is given by the IUPAC which means: the invention, design and utilization of chemical product and process to reduce or to eliminate the use and production of unsafe substance.

Published: April 2024

Purpose: Magnesium sulfate (MgSO4) emerged as an adjunctive therapy to help manage acute severe asthma refractory to the first-line therapy, such as oxygen, ipratropium, corticosteroids, and bronchodilators. Despite the known benefits of MgSO4, limited information is available regarding potential adverse effects (AEs). We aimed to investigate potential AEs and clinical response of intravenous MgSO4 by assessing vital signs and the modified Wood-Downes score (mWDS), a relevant clinical scoring system. Methods: This investigation constitutes a prospective, single-arm study, conducted from June 2022 through May 2023, in a pediatric emergency department of the quaternary public hospital in Brazil. This study included all children aged 3-14 years who visited the pediatric emergency department during the period and underwent a 6-hour continuous infusion of MgSO4 at 50 mg/kg/hour, against acute severe asthma, a case refractory to the first-line therapies. We evaluated the safety and efficacy of the infusion by using vital signs and the mWDS. Clinical response was defined as a reduction of at least 1 point in the scoring system.Results: We analyzed a total of 42 children including 24 boys (57.1%), whose mean age was 5.7 ± 2.4 years. The 6-hour continuous infusion of MgSO4 reduced mWDS from 3 (interquartile range, 3-4) to 2 (2-3) (P < 0.001) and resulted in the clinical response in 30 children (71.4%) without an AE. After the infusion, 13 of the 15 children (86.7%) classified as having moderate asthma exacerbation (mWDS, 4-6) were improved to having mild asthma exacerbation (mWDS, 1-3) (P < 0.001). The mean serum magnesium concentration after the infusion was 4.7 mg/dL. Pneumonia and viral infection did not predict the clinical response.Conclusion: This study indicates the safety and efficacy of the 6-hour continuous infusion of MgSO4 as a therapeutic option for acute severe asthma, which is refractory to the first-line therapy.
Modeling Climate and Tectonic Controls on Bias in Measured River Incision Rates
Authors: DeLisle Clarke , Yanites Brian J
Published: April 2024

Rates of land surface processes provide insights into climate and
tectonic influences on landscape dynamics. River incision rates into
bedrock are estimated by dating perched landforms such as strath
terraces, assuming a constant bedrock incision rate from terrace
abandonment to present. These estimates express biases from the
stochastic nature of river incision and from using a mobile channel
elevation as a reference frame. No existing mechanistic framework fully
addresses these biases. We introduce a 1-D river evolution model
incorporating fluvial mechanics, sediment dynamics, tectonics, and
climatic factors to predict these biases and assess their sensitivity to
climate and rock-uplift rate. Findings suggest biases intensify under
highly variable climates and slow rock uplift, with the period of
climate being a primary control. Our model improves river incision
measurement reliability, impacting paleoclimate and tectonic
geomorphology reconstructions.

La alta demanda de materias primas convencionales para la fabricación de alimentos hace que, día a día, los costos de estas se eleven, ocasionando un 70% de los gastos de producción en alimentación. Se hace necesario buscar fuentes alternativas de alimentación eficientes para la piscicultura. El objetivo fue determinar coeficientes de digestibilidad aparente (CDA) de Tithonia diversifolia, Gliricidia sepium, Cratylia argentea en juveniles de Piaractus brachypomus. Se seleccionaron 400 juveniles de cachama blanca con peso promedio de 125 g. Los cuales se dividieron en 4 grupos. Para la recolección de heces se utilizaron nueve tanques de fibra de vidrio con capacidad de 200 L con fondo cónico (Sistema Guelph modificado). Los coeficientes de digestibilidad aparente (CDA) de los ingredientes fueron determinados por el método indirecto. Las dietas experimentales estaban compuestas por 69.5% de Dieta Referencia (DR), 0.5% de marcador inerte (Cr2O3) y 30% de Harina de hojas de la materia prima a evaluar. Los CDA de proteína para Gliricidia sepium fueron de 54.22%; para Tithonia diversifolia, de 35.7%; y Cratylia argéntea, de 23.9%. La harina de hoja de Gliricidia sepium es una materia prima alternativa que puede usarse en alimentación de  cachama blanca, por su buen porcentaje de proteína bruta de 26.55%, sumado a la capacidad de aprovechamiento en un 54.2% (CDA); lo que equivale a una digestibilidad de proteína de 14.9%, si se tiene en cuenta que esta especie tiene un requerimiento de proteína del 32%.

Authors: Ortega Johana P. , Yossa Martha I.
Published: April 2024

Los peces detritívoros son la base de la cadena alimentaria y están ampliamente distribuidos en las cuencas neotropicales, los Prochilodus son representativos de este grupo y el bocachico llanero o coporo (Prochilodus mariae) es de interés comercial en acuicultura. Para evaluar el desempeño productivo en alevinos de coporo con dietas isotópicas, fueron conformados dos tratamientos: dieta comercial (δ13C -20.93±0.34) y dieta experimental (δ13C -24.6±0.9) suministradas durante sesenta días. Parámetros de peso medio, longitud media estándar, ganancia de peso (GP), tasa de crecimiento específico (TCE) y factor de conversión alimenticia (FCA) fueron determinados. La contribución y fraccionamiento de la dieta fueron estimados a partir de las lecturas isotópicas en muestras de músculo. El peso y longitud estándar del coporo fue superior en el tratamiento de la dieta comercial (DC). En los parámetros GP y TCE hubo diferencia significativa (P<0.05) entre tratamientos, siendo el tratamiento DC siempre superior frente a la dieta experimental (DE). La contribución relativa de la DC y DE fue de 59.2 y 53.4% respectivamente, en cuanto que el mayor fraccionamiento de la dieta en carbono y nitrógeno fue de la DE en 1.97 y 1.14%0 respectivamente. La relación entre la contribución de la dieta y la ganancia de peso fue más eficiente para DC en términos de carbono, contrariamente, la eficiencia del nitrógeno fue con DE. Aunque la contribución de las dietas fue inferior a 60%, ambas contribuyeron a mejorar el desempeño del coporo.

Published: April 2024

In this work, the effect of bi-substitution of Zn and Ce at Cu and Ti sites
on microstructure and dielectric properties of CaCu3Ti4O12 ceramics was
investigated. The doped CaCu3-xZnxTi4-xCexO12 (CCZTC-x) powders (where x =
0.1, 0.2 and 0.3) were successfully synthesized via semi-wet route and the
corresponding ceramics were obtained by sintering at 950 ?C for 14 h in air.
The presence of major cubic CaCu3Ti4O12 phase along with minor secondary CuO
phase was observed by X-ray diffraction analysis. Scanning electron
microscopy analyses confirmed microstructure consisting of cubic-shaped
grains and grain sizes of 0.76, 0.87 and 0.98 ?m, for the ceramics with x =
0.1, 0.2 and 0.3, respectively. The high value of relative dielectric
constant of 1500 at 100Hz was found for the sample with x = 0.3, which may
be regarded as having semiconducting grains surrounded by insulating grain
boundaries. In addition, conductivity of the sintered samples decreases with
doping concentrations and the activation energies of the samples with x =
0.1, 0.2 and 0.3 are 0.93, 0.76 and 0.74 eV, respectively.
Investigating interfacial cracks in bi-materials through a 4-point bending model analysis
Authors: Mankour Abdeljelil , Belabbes Bachir
Published: April 2024

This study focuses on examining the failure behavior of interfacial cracks in bimaterial structures. Bimaterials present a unique challenge due to their composition, consisting of two materials that can be homogeneous and isotropic, with a specific emphasis on the ceramics/metal combination. The disparity in elastic and physical properties between these materials leads to stress singularities and embrittlement of the interface. In order to investigate the behavior of an interfacial crack without propagating into the individual materials, numerical simulations of a 4-point bending model were conducted. The stress intensity factors were computed at the crack tip to determine the energy release rate, which is a crucial parameter in evaluating interfacial crack behavior. The energy release rate, along with the mixed mode angle (G, ?), provides insights into the crack?s response. The findings demonstrate that an increase in the thickness ratio (H1/H2) of the assembled materials, as well as a reduction in the Young?s modulus ratio (E1/E2), result in higher energy release rates for interfacial cracks in bimaterials. This indicates that the properties of the assembled materials play a significant role in determining the dominant mode of crack propagation tendency.
Innovations and variability of modern English-language Russia-centred discourse: a pilot corpus study
Authors: Белоглазова Е.В. , Каменева А.Д.
Published: April 2024

В статье исследуется англоязычный руссо-центрический дискурс в аспекте его территориальной и темпоральной вариативности. Анализ британского и американского подкорпусов дискурса выявил общие для обоих вариантов дискурса когнитивные доминанты, при вариативности их репрезентантов. При этом 40 % выявленных репрезентантов не были ранее зафиксированы в специализированном словаре и представляют собой ксенонимические новации английского языка, обращенного в область русской культуры. Исследование позволяет оценить динамику развития англоязычного руссо-центрического дискурса, распадающегося вслед за языком в целом на региональные варианты.

The paper focuses on the English-language Russia-centred discourse in the light of its temporal and regional variability. The study aims at identifying the key trends in the development of modern foreign-language discourse about Russia, in particular the specific features it develops within the main varieties of the English language (British Standard English and American Standard English). The analysis revealed that both subcorpora share common cognitive mainstays, while their lexical representation varies across regional varieties. 40% of the identified discourse markers were not previously recorded, being xenonymic innovations of the Russian-culture-oriented English. This observation allows postulating the dynamic development of the Russia-centred discourse, which continues to expand its vocabulary.

Vasily Belovas a regional brand
Authors: Ильина Е.Н. , Драчева Ю.Н.
Published: April 2024

Статья исследует процесс формирования регионального бренда Василий Белов на основе сведений о жизни и творчестве писателя-вологжанина в текстах массовой коммуникации начала ХХI в. Привлекается внимание к результатам медиатизации личности и творчества В. И. Белова: медиаобраз писателя становится более объективным, насыщенным фактами, многосторонним; брендирование же образа В. И. Белова сужает его восприятие аудиторией до вологодского «деревенского» писателя из Тимонихи.

The article describes the process of forming Vasily Belov regional brand on the basis of the verbal representation of his personality as a Vologda writer, his biography and literary works in mass communication of the early 21stcentury. The conclusions draw attention to a high degree of mediatization of Belov’s personality and his literary works. On the one hand, the media image of the writer becomes more objective, more factual and multifaceted; on the other hand, the branding of the writer’s name diminishes the level of perception by the audience, and V. Belov is seen just as a writer from one of Vologda villages – Timonikha.
Жанр «блог» в аспекте лингвокогнитивного консонанса и диссонанса участников коммуникации
Authors: Кислицына Н.Н. , Норец М.В.
Published: April 2024

Целью исследования является характерологическое описание лингвокогнитивных особенностей жанра «блог» как отдельного вида интернет-коммуникации с фокусом на дискурсивной деятельности коммуникантов. В процессе исследования используется разнообразный аналитический инструментарий, включающий в качестве основных: конверсационный, концептуальный и критический дискурс-анализ. Материалом исследования послужили тексты блогов, представленные в качестве своеобразного варианта развития классического литературного жанра дневника. Результаты исследования показывают, как индивидуальная и групповая языковая деятельность (language practice) оказывает влияние на формирование социокультурных норм и форм общения, а также сама трансформируется в рамках возможностей, предоставляемых современными коммуникационными каналами.

The purpose of the study is a characterological description of the linguocognitive features of the “blog’ genre as a separate type of Internet communication with a focus on the discursive activity of communicators. In the course of the research various analytical tools including the conversation, conceptual and critical discourse analysis are used. The texts of blogs treated as the development of a diary genre are analyzed in the aspect of linguocognitive and multimodal approaches. The results of the research show the way individual and group language practice, on the one hand, influences the formation of sociocultural norms of communication, and on the other hand, is transformed under the impact of new communicative channels.
The image of teplushka in the prose of the 1920s
Authors: Юньсюе Ц.
Published: April 2024

Характер литературных текстов вне зависимости от периода их создания определяется сложившейся социальной обстановкой. Послереволюционные 1920-е гг. – один из самых значимых периодов в истории русской литературы, ставший временем политических потрясений и хаоса, поиска нового пути для развития культуры. Ряд писателей обращается к образу теплушки как символу дороги, пути, движения по новой России. Писатели сочетают этот образ с темой войны и голода, размышляют о судьбе России, изображают людей из разных социальных слоев, таких как солдаты, профессоры, женщины и дети, которые оказались заложниками экстремальных ситуаций в период хаоса, открывают читателям панораму динамических процессов 1920-х гг. Цель данной работы – проанализировать образ теплушки в советской прозе 1920-х гг. и выявить общий лейтмотив литературных произведений этого периода.

The character of literary texts, regardless of the period of their creation, is determined by the surrounding reality, the social situation, and the prevailing circumstances. The post-revolutionary 1920s is one of the most exceptional periods in the history of Russian literature, which was a time of political upheaval and chaos, and a time of searching for a new path for the development of culture. A number of writers appeal to the image of the teplushka as a symbol of the road, the path, the movement on the new Russia, combining this image with the theme of war and famine, reflecting on the fate of Russia, depicting people from different social strata, such as soldiers, professors, women and children in extreme situations during the chaos, opening to readers a panoramic view of the dynamic processes of real life in the 1920s. The aim of this paper is to analyse the image of the teplushka in Soviet prose of the 1920s and to identify the common leitmotif of literary works of this period.

Background Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a critical care treatment option for patients with refractory cardiogenic shock. This method of temporary support of the cardiorespiratory system gives us and the patient time to restore organ function or is a «bridge» to other methods of treatment. Nevertheless, the issue of identifying the optimal time for VA ECMO implantation in patients with acute myocardial infarction complicated by refractory cardiogenic shock remains relevant.

Aim To evaluate the efficiency of extracorporeal membrane oxygenation in various clinical situations in patients with acute myocardial infarction complicated by refractory cardiogenic shock and post-infarction damage to the valves of the heart.

Material and method We present 3 patients with acute coronary syndrome complicated by refractory cardiogenic shock, of different age groups and comorbidities, who underwent veno-arterial extracorporeal oxygenation in various SCAI shock stages, and mechanical complications associated with acute myocardial infarction.

Results In all the cases, stabilization of hemodynamics and heart function was achieved, and there were no hypoxic disorders of organs. In one case, a hemorrhagic complication associated with the VA ECMO procedure was noted. In one case, VA ECMO was performed as an intermediate stage for the correction of post-infarction mitral valve injury.

Conclusion These clinical cases demonstrate the efficiency of the timely start of VA ECMO before the development of organ dysfunction, which allows restoring myocardial function, and helps maintain hemodynamic normalization before the cardiac surgical stage of treatment.

Aim of study To study the effect of local phage therapy alone and in combination with systemic antibiotic therapy on the dynamics of microflora colonizing the skin of the periwound area during surgical treatment of infected burn wounds.

Material and methods Scientific hypothesis: the use of local phage therapy in monotherapy in the treatment of burn wound infections reduces the risk of colonization of the skin of the periwound area by bacteria of the ESKAPE group. The experimental study analyzed the results of microbiological studies of washings from the skin surface of 40 animals with infected burn wounds, in the course of phage therapy in monotherapy and in combination with systemic antibiotic therapy.

Results In the group of animals receiving phage therapy alone, the proportion of ESKAPE group bacteria colonizing the skin of the periwound area at the time of completion of the course of antimicrobial therapy was 9%, while in the group receiving phage therapy in combination with systemic antibiotic therapy it was 43% (p=0.011).

Conclusion The use of local phage therapy in single mode during the surgical treatment of infected burn wounds reduces the risk of colonization of the skin of the peri-wound area by pathogens of the ESKAPE group. At the same time, systemic antibiotic therapy causes an imbalance of resident and transient skin microbiota in the periwound area and an increase in the frequency of its colonization by pathogens of the ESKAPE group.
