Published: February 2022

The majority of Indonesians who are known to use social media as a means of communication and entertainment are certainly no strangers to the term â€˜memeâ€™. A popular meme phenomenon is the use of the word tenggelamkan (sink) at the end of the discourse popularized by Susi Pujiastuti, the former Minister of Fisheries and Marine Affairs. The purposes of this study was to find out the styles of language used in memes using the word tenggelamkan and their implications. The data of this study were taken from various pictures on the Internet with 15 memes in total. The method applied was descriptive-qualitative by using Griceâ€™s theory of conversation maxims. The results of this study show that the themes used in memes with the word tenggelamkan include love, friendship, corruption, worship, and food. The use of language styles reflected from the memes are cynicism, paradoxes, and rhetoric. Meanwhile, the impicatures of meme the memes comprise satire, suggestion, and a combination of both.

Published: February 2022

Background/Aim. One of the complications that can occur during pregnancy is the development of preeclampsia (PE). The main characteristics of this condition are high blood pressure and very often signs of kidney damage or other organ damage. The condition affects 5?7% of all pregnant women and is one of the main factors of maternal and perinatal morbidity and mortality worldwide. The aim of this study was to investigate the structural and functional modifications of high-density lipoprotein (HDL) particles during high-risk pregnancies (HRP) for PE development. Methods. The longitudinal prospective study included a total of 91 pregnant women with a HRP for developing PE. Out of this total number, 71 women did not develop PE until delivery, and this group was designated as the group without PE (WPE). The rest of the 20 HRP women developed PE before delivery and were designated as the PE group. The blood was sampled toward the end of each trimester and before the delivery. The distribution of HDL particles was determined by the vertical 3?31% polyacrylamide gradient gel electrophoresis method. The antioxidative capacity of HDL particles was measured by the activity of the HDL-associated enzyme ? paraoxonase 1 (PON1). PON1 activity was determined by the method of kinetic spectrophotometry from serum samples. Results. The results have shown that the proportions of HDL2b particles significantly increased in the 2nd trimester (p ? 0.05) and remained increased until the end of pregnancy in the WPE group. PON1 activity was significantly higher in the 3rd trimester (p < 0.05) of the WPE group. In the PE group, we found that the proportions of HDL3a particles significantly decreased in the 2nd trimester (p < 0.05) and remained decreased until the end of pregnancy. PON1 activity has not changed in the PE group during pregnancy. Conclusion. Dyslipidemia in pregnancy could be associated with different modifications of HDL particles. The adaptive pregnancy mechanisms expressed as a functional modification of HDL particles in pregnant women who develop PE seem inadequate and, therefore, lose their atheroprotective role.

Published: February 2022

Background/Aim. Cataract surgery is one of the most often performed surgical interventions. The predominant method in Western countries is phacoemulsification, while in developing countries, the extracapsular cataract extraction (ECCE) method remains popular. The aim of the study was to evaluate the cost-effectiveness of these two cataract surgery techniques from the provider?s perspective if operation complications were the outcome of the interest. Methods. The data were obtained from the Department of Ophthalmology of the General Hospital Krusevac during a one-year period. A total of 1,179 surgeries by five surgeons were performed. The cost-effectiveness was evaluated using the decision tree. All probabilities were calculated based on the likelihood of the occurrence during the study period. Only direct costs were considered, and values were taken from the documentation at the hospital and the official price list of health services. One- and two-way sensitivity analyses were performed. Results. The total cost per patient in the phacoemulsification group was 71,008.70 Serbian dinars (RSD), while the total cost in the ECCE group was 74,340.36 RSD. At the same time, phacoemulsification shows higher effectiveness than the ECCE method, with 87% and 57% of patients without complications, respectively. With these results, phacoemulsification was the dominant strategy compared to ECCE. The sensitivity analysis revealed that the results are sensitive to the number of performed operations per year. Conclusion. The phacoemulsification technique seems to be the preferred technique for cataract surgery. All the investment in phacoemulsification equipment and consumables is justified if the number of surgeries per year exceeds 350.

Growing evidence indicates an important link between gut microbiota, obesity, and metabolic syndrome. Alterations in exocrine pancreatic function are also widely present in patients with diabetes and obesity. To examine this interaction, C57BL/6J mice were fed a chow diet, a high-fat diet (HFD), or an HFD plus oral vancomycin or metronidazole to modify the gut microbiome. HFD alone leads to a 40% increase in pancreas weight, decreased glucagon-like peptide 1 and peptide YY levels, and increased glucose-dependent insulinotropic peptide in the plasma. Quantitative proteomics identified 138 host proteins in fecal samples of these mice, of which 32 were significantly changed by the HFD. The most significant of these were the pancreatic enzymes. These changes in amylase and elastase were reversed by antibiotic treatment. These alterations could be reproduced by transferring gut microbiota from donor C57BL/6J mice to germ-free mice. By contrast, antibiotics had no effect on pancreatic size or exocrine function in C57BL/6J mice fed the chow diet. Further, 1 week vancomycin administration significantly increased amylase and elastase levels in obese men with prediabetes. Thus, the alterations in gut microbiota in obesity can alter pancreatic growth, exocrine function, and gut endocrine function and may contribute to the alterations observed in patients with obesity and diabetes.

Authors: Shao Yuping , Abualhamayl Abdullah Jameel
Published: February 2022

College students are prone to psychological changes and personality distortions under heavy pressure. It will lead to catastrophe if it is not promptly guided or improperly used to reduce stress and relax. Now we integrate holistic education into the construction of the mental health education system in colleges and universities. This is conducive to solving practical problems and improving the effectiveness of system construction. We set up a differential equation model (DCE) based on the discrete choice to study mental health due to practice. At the same time, we adopt the mutual influence model of penetrating dissemination of thoughts and public opinion and human behaviour, and establish the SEIR DCE with constant input and bilinear incidence rate. The experiment verifies the algorithm’s effectiveness on the model of whole-person mental health education activities in colleges and universities.
Analysis and Prediction of College Students’ Mental Health Based on K-means Clustering Algorithm
Authors: Liu Yanwu
Published: February 2022

Mental health is an important basic condition for the adult development of college students, and education workers gradually pay attention to the strengthening of mental health education for college students. In this paper, a psychological management system based on the K-means clustering analysis method is proposed. Based on the basic functions of the traditional system, the students’ psychological data are reutilised by using the idea of data mining. By optimising the iterative process of the K-means algorithm, the valuable parts of a large number of precipitation students’ psychological data are extracted. A data model is established and it provides decision guidance for managers to scientifically manage students’ mental health process. The system establishes the data mining model in the process of analysis, carries on the mining to the students’ psychological data in the database, analyses the different college students’ mental health state characteristics and provides the corresponding solution. The part of the test drew on mental health data from 1,000 students at a school, and the results show that the system uses the k-means algorithm to divide students into 3 categories, which are 20.6%, 31.9% and 47.1% respectively, which are 1.6% different from the data test results in the ideal state.
Who is Most Vulnerable? Exploring Job Vulnerability, Social Distancing and Demand During COVID-19
Authors: Johnston Richard , Hogg Ryan , Miller Kristel
Published: February 2022

COVID-19 has resulted in global lockdowns, social distancing and demand fluctuations. Existing crisis management research often provides a retrospective account of strategy making after a crisis. Limited studies have explored the factors which aid policy responses during an ongoing crisis. This research helps fill this gap by exploring the influence Covid-19 had on job vulnerability during the first wave of the COVID-19 crisis (spring and summer of 2020). We explore Northern Ireland (NI) which historically has experienced disadvantages. We utilise point-in-time modelling which considers contextual variations. The findings reveal that a reduction in social distancing reduces the vulnerability of over 30,000 jobs, however, ongoing uncertainties regarding demand will have a more significant longer-term impact on job vulnerabilities. We identify how COVID-19 may impact sectors, groups and geographies differently. We provide policy recommendations on how to alleviate the impact COVID-19 has for job vulnerability across the NI economy.
Teaching in Flexible Spatial and Digital Conditions

Published: February 2022

This study explores the opportunities and challenges of teaching under flexible spatial and digital conditions of the learning environment of a newly build school analyzing how teaching is organized and what curricular genres can be discerned, what resources and practices are offered to stimulate students meaning-making and what framing, relations and accessibility can be discerned in the flexibility of furniture and classroom space. The analyses of one teacher team’s planning and teaching of the thematic work project on Space in years 2-3 (8-9 old children) reveals varied teaching strategies between teacher-led and student-centered forms offering students linguistic, visual and audiovisual resources to make meaning of shared content via different subjects. Spatial framing allows for free movement or static and focused teaching strategies of rather traditional forms of assignments and assessment. These young students practice reading comprehension, both of written texts and films, that also serves building their knowledge about space, thus engaging in skills discourse in combination with thinking and learning discourse.
Students' Insights from Interactive Visualizations Arranged Multimodally in Knowledge Visualizations
Authors: Bodén Ulrika Christina , Stenliden Linnea , Nissen Jörgen
Published: February 2022

In this study, a visual analytics application is put into practice in Swedish secondary school social science classrooms. The application offers support to analyse vast amounts of data through interactive data visualizations. Previous studies have demonstrated that the visual interactive interface challenges the traditional practice in school, where students usually demonstrate their knowledge by means of written texts. Thus, this study examines what happens if students work with more malleable, adaptable, or fluid modes when attempting to express their conclusions from work with interactive data visualizations. It aims to detect patterns in how knowledge visualizations are produced and arranged multimodally. Inspired by design-based research, the study conducted two classroom interventions followed by video captures. It employed a socio-material semiotic approach, which enables the study of interactions between both social and material actors. Three patterns emerged when students’ insights were translated into knowledge visualizations – exploring, gathering, and inserting. It became obvious how different actors taking part of such a digital multimodal writing activity affect and change every actor/everyone/everything, which in turn transfers, relocalizes, reformulates, and re-presents the communicated message. Knowing how knowledge visualizations are produced might strengthen students’ visual abilities when transforming insights multimodally.

Published: February 2022

Using data from focus group interviews, this study aims to analyze the perceived opportunities and challenges encountered by groups of secondary school teachers regarding the assessment of multimodal texts. Previous research has shown that digital technologies introduce new kinds of texts in the classroom. The possibility of combining verbal text with image, sound, and movement has an impact on students’ text production. However, the changing role of writing on the screen has left teachers uncertain of how to assess these new forms of texts. Apart from attending to digital competence, assessing multimodal texts may involve following writing conventions and organizing text using different resources and components. Quality in multimodal texts may concern using multimodal components to communicate complex ideas effectively, which may or may not be noticed by teachers. The data is based on group interviews with 11 secondary school teachers at two different schools. The study conducted a thematic content analysis using the analytical concepts of transformation, recognition, design, and form and meaning. Findings show that teachers find it challenging to acknowledge certain qualities in students’ multimodal texts without support from the steering documents. On the other hand, they notice opportunities to follow students’ learning processes. In addition, they stress an increased opportunity and need for shared assessment across school subjects. The article concludes with a discussion of tensions regarding opportunities and challenges when assessing students’ multimodal texts in relation to the different subject syllabuses.

Estos antibióticos de mayor consumo presentan niveles de excreción (sin cambios) en la orina superiores al 30%, y particularmente la ciprofloxacina, la azitromicina y el sulfametoxazol son encontrados con alta frecuencia en las aguas residuales y ambientales colombianas. Es importante remarcar que el presente trabajo se constituye en un documento de base sobre el consumo, excreción y presencia de antibióticos en aguas residuales de Colombia, con información accesible para la comunidad en general, y representa un punto de partida para trabajos futuros sobre consumo de fármacos, impacto de los antibióticos sobre las aguas ambientales colombianas, e investigaciones sobre alternativas de eliminación de estos fármacos en matrices como la orina.
Different effect of nitrogen sources in autotrophic and mixotrophic culture of Scenedesmus sp for biomass and carotenoids production using acidic coal mine drainage effluents
Authors: Urbina-Suárez Nestor Andres
Published: February 2022

In the present study, the conditions for autotrophic and mixotrophic culture of Scenedesmus sp were established. Effluents from acidic coal mine drains were used to study biomass and carotenoid production, both under autotrophic and mixotrophic conditions in relation to the effect of different sources of nitrogen: sodium nitrate, urea and ammonium phosphate. Pollutant removal was determined, such as COD, TOC, heavy metals, ions and total suspended solids. Batch cultures lasted nine days and biomass production, carotenoids and pollutant removal were compared in each condition. The highest biomass concentration reached was 1.2 g/L in the mixotrophic culture with urea, followed by the culture with sodium nitrate of 0.9 g/L in a C/N ratio of 6:1. The highest carotenoid specific concentration was reached in the mixotrophic culture with sodium nitrate, 19.43 mg carotenoids /g biomass. The culture with ammonium phosphate was found to be inhibitory for the growth of the microalgae with the lowest results of all the parameters except for the autotrophic culture where the concentration of carotenoids was very similar to those reached with sodium nitrate and urea. Finally, the mixotrophic culture with urea presented the highest removal percentages, being 86.97% for total iron, 58.29% for chlorides and 92.5% for COD.

La ozonización catalítica (OC) es una tecnología prometedora en términos de eficiencia y costo energético como tratamiento de efluentes industriales que poseen contaminantes de preocupación emergentes, ya que mejora las capacidades oxidativas del ozono a través de catalizadores que promueven su descomposición y la generación de especies radicales oxidantes, los cuales reaccionan con prácticamente cualquier compuesto presente en los efluentes. Este artículo estudió el estado y evolución de la OC mediante una revisión de la literatura y un análisis bibliométrico combinado con la técnica de curva S para analizar cuantitativamente 1714 publicaciones en SCOPUS y SciELO Index desde el año 1973 al 2021.
Los resultados mostraron que (1) el número de publicaciones a nivel mundial se inició en 1973 a tuvo 189 documentos  en 2021; (2) China es el país con mayor número de publicaciones y citaciones anuales (958 y 19088, respectivamente) y es un país central en redes de cooperación internacional; (3) tanto el estado del arte como el análisis de co-ocurrencia de palabras clave mostró que la investigación ha priorizado mecanismos de reacción de la OC, expresiones cinéticas, catalizadores, y desde 2016, la aplicación a escala piloto en conjunto con otras tecnologías avanzadas de oxidación; (4) El compuesto  con más investigaciones es el ácido oxálico y desde 1999 ibuprofeno y atrazina; (5) en América Latina, Brasil es el país con más publicaciones (32) y con mayor número de redes de cooperación internacional y (5) Applied Catalysis B: Environmental y Journal of the Brazilean Chemical Society (América Latina) son las revistas con mejor cuartil que publican sobre OC. Finalmente, la curva S indicó que la OC se encuentra en etapa de crecimiento en términos de madurez cientifica, exhibiendo un gran potencial en I+D.

We report the case of a 28-year-old male patient with a history of voluntary ingestion of a metallic pellet 20 days before who was transferred to our department with typical symptoms of acute appendicitis. Under that circumstances he underwent conventional appendectomy. The analysis of the preoperative imaging tests and the intraoperative findings help to identify the association between the foreign body and acute appendicitis. Ingestion of foreign bodies, either accidental or voluntary, is an extremely uncommon cause of acute appendicitis; thus, there are few reports in the international literature. This is the first case reported in Argentina.

The COVID-19 pandemic during initial lockdowns created a problematic situation in which individuals were forced to remain within their homes and were forced to follow social distance restrictions for the well-being of themselves and others. In response, people use social networking sites on mobile phones to gather information about the COVID-19 epidemic. This study aims to investigate the influence of lockdowns on mobile phone usage among university students. Moreover, the harmful effects of COVID-19, such as anxiety, social isolation, and nomophobia among national and international students, are also investigated. The total sample size for this cross-sectional study is 438 individuals. The sample consists of Pakistani students studying at local universities (58.7%) and Pakistani students studying abroad (41.3%). The indigenous data is gathered through convenience sampling. The snowball sampling approach is adopted to acquire data from overseas. The findings show that the excessive use of mobile phones for browsing social networking sites to get information about the pandemic caused COVID-19 anxiety, nomophobia (“no-mobile-phone” phobia), and feelings of social isolation. Our results indicate that the COVID-19 outbreak greatly impacted students’ massive mobile phone use and psycho-social well-being, regardless of their geographic location.
Huxley’s “Jungle of Noise” in Point Counter Point
Authors:   Alexandru Ioan Cuza University (Romania), Bădulescu Dana
Published: February 2022

Point Counter Point, Aldous Huxley’s experiment with the ”musicalisation of fiction” (PCP 384, –References to Point Counter Point will be abbreviated hereon in PCP–) was published in 1928, the end of a decade of post-war trauma, conflicting ideologies, proliferating scientific theories, new technologies and reckless hedonism. These amalgamated aspects found their expression in the novel’s cubist montage, contrapuntal orchestration and cynical tone. I argue that, in tandem with the experimental poetry and prose of Huxley’s contemporaries, Point Counter Point set the tone for a new literary culture on both sides of the Atlantic. This approach accounts for the novel’s experimental techniques and design, starting from the ”jungle of noise” (65) metaphor.
‘The Times Have Changed’: American Self-Discovery in Pearl S. Buck’s East Wind West Wind
Authors:   Escuela Oficial de Idiomas,A Coruña (España), Fernández-Rodríguez Carmen María
Published: February 2022

East Wind West Wind registers the coming of age of Chinese women as seen with Western eyes. Buck’s novel deals with the clash of two ideologies: the Chinese tradition, which assigned a specific and very limited role to women in society and promoted submission, and the Western world, which is epitomized in multiple ways in the story. The image of 1920s American society as a liberating force is perceived in the relationship with the husband and the daughter-in-law representing alterity and sorority at the same time. Buck makes her political allegiance to the West explicit and East Wind West Wind showcases how the Western world helps the protagonist to know herself better and to accept herself.
The Roar of Modernity: Metropolitan Soundscapes and the Making of the Modern Subject in Dos Passos’ Manhattan Transfer
Authors:   University of Cologne (Germany), Klein Sascha
Published: February 2022

This article explores the specificities and psychological effects of urban noise in John Dos Passos’ novel Manhattan Transfer. It seeks to elucidate how Manhattan’s soundscape is represented on the novel’s formal and content level and how it assumes an agency in its own right, when ceaselessly enveloping the novel’s characters. The city’s specific acoustic regimes, therefore, prove much more instrumental in constituting the characters as modern subjects than other sensorial dimensions. Within a thus enacted metropolitan panacousticon, the urban subject is crucially defined not only as a noise source in itself, but as always already overheard by a supposed other.
Fashionable Flappers: Constructing Femininity in F.S. Fitzgerald’s The Offshore Pirate and The Ice Palace
Authors:   Alexandru Ioan Cuza University (Romania), Milică Iulia Andreea
Published: February 2022

Transition, dynamism, prosperity, freedom, and youth characterize the Roaring Twenties. Women experienced some of the most radical changes in all areas of life, private and public, and fashion reflected this newly gained freedom: shorter dresses, short hair, make-up, deep necklines, and a boyish charm. Francis Scott Fitzgerald’s writings mirror this world of contradictions: its enthusiasm and frivolity, its freedom and failures. This article analyzes two of Fitzgerald’s earliest short stories, The Offshore Pirate and The Ice Palace, in order to point out the writer’s ambiguous way of representing the flapper, positioned at the crossroads between rebellion and conventionality, emancipation and superficiality. The analysis is mainly based on an evaluation of fashion imagery, a tool into decoding Fitzgerald’s manner mainly based on an evaluation of fashion imagery, a tool into decoding Fitzgerald’s manner of constructing femininity.
No Flappers in Wonderland?: Illustrating Alice’s Adventures in Wonderland in the 1920s
Authors:   Universidade da Coruña (España), Valeiras-Fernández Andrea , Lorenzo-Modia María Jesús ,   Universidade da Coruña (España)
Published: February 2022

The social and economic context of the post-war period of the 1920s had a reinvigorating effect on children’s literature, the fairy tale, and fantasy genres. Moving beyond their characteristic didactic and moral functions, these narratives began to be seen as safe places in which one could escape from reality and seek refuge in a world of adventure. Illustrations had a significant role in the new development of these genres, stimulating the imagination and helping to create fantastical realms for readers. Lewis Carroll’s Alice’s Adventures in Wonderland (1865) had already served that purpose in the Victorian era, and editions and versions of the work for a new 1920s generation would present re-interpreted illustrations, ones which were rendered more appropriate for the new context and which reflected some avant-garde tendencies, whilst not overlooking the essence of the original.
An echocardiographic study of the effect of obesity on systolic and diastolic functions of the left ventricle in hypertensive adults
Authors: Shree C. Mamatha , Prashanth K. S. , Girija B.
Published: February 2022

Objectives:

The objectives of the study were to examine the effect of obesity on echocardiographic parameters of systolic and diastolic functions of the left ventricle (LV) in asymptomatic hypertensive adults.

Materials and Methods:

A cross-sectional study was conducted with 100 individuals (65 males and 35 females). Their blood pressure and body mass index were recorded following which they were divided into obese hypertensives and non-obese hypertensives. Echocardiographic examination was done, and parameters indicating LV geometry and function were recorded. Data were statistically analysed for differences. An unpaired t-test was used considering P < 0.05 as a significant value.

Results:

Echocardiographic parameters of LV diastolic function were significantly altered in obese hypertensives compared to non-obese hypertensives (P < 0.05). About 58% of non-obese hypertensives and 78% of obese-hypertensives had LV diastolic dysfunction. About 6% of non-obese hypertensives and 8% of obese-hypertensives had LV systolic dysfunction.

Conclusion:

Obesity in hypertensive individuals adds risk for diastolic dysfunction. The number of subjects falling into categories of mild-to-moderate diastolic dysfunction was considerably higher in the obese hypertensives compared to the non-obese hypertensives.
