Juvenile Xanthogranuloma: the benignity behind an atypical lesion
Authors: Bassi Roberta , Bittencourt Juliana , Barbosa Fernanda
Published: October 2023

Objective: To describe a rare case of Juvenile Xanthogranuloma (JXG) in an infant in order to inform more about this pathology little described in academia, thus avoiding unnecessary treatments and approaches. Case description: This is a 4-month-old infant with a single nodular lesion in the abdomen that has progressively evolved since birth. A crusty-looking lesion with small adjacent nodules, central ulceration and blurred borders, approximately 3 centimeters in diameter. With the diagnostic hypothesis of impetigo raised, he used topical and oral antibiotics, without success. Then, suspected of dermatophytosis, he used antifungal agents, without improvement. Due to the persistence of the lesion, an ultrasound of the lesion was requested and referred to a dermatologist. Only after the biopsy was the diagnosis of JXG confirmed. Comments: JXG is a rare and benign pathology, belonging to the group of non-Langerhans histiocytosis that typically appears in pediatric age. Lesions most commonly occur on the skin and have a characteristic morphology. They are usually asymptomatic and spontaneous regression is expected in approximately five years. However, the disease can lead to extracutaneous involvement and other important pathologies may be related to the condition, thus requiring an extension of workup to prevent irreversible sequelae to the patient.

Authors: Amaral Maria Eduarda , Kotsifas Sofia , Cornelsen Luisa , Cruz Aristides
Published: October 2023

INTRODUCTION: Vitamin D intoxication among nurslings (serum levels of 25-hydroxyvitamin D above 150 ng/mL) is a factor in the development of hypercalcemia, an uncommon condition in pediatrics. OBJECTIVE: Report a case of severe hypercalcemia caused by hypervitaminosis D in a nursling. CASE REPORT: 5-months-old masculine child, exclusively breastfed, referred to a specialist with suspected cows milk protein allergy because he failed to gain weight in the last month and presented with blood and mucus in stool. Beyond failure to thrive, the patient evolved with somnolence, apathy and hypotonia. Laboratorial tests revealed hypercalcemia (serum calcium of 17,40 mg/dL) and hypervitaminosis D (180 ng/mL). The hypothesis of vitamin D intoxication was raised and later confirmed by the laboratorial analysis of the supplement offered to the nursling, which revealed a vitamin D concentration 46 times greater than the originally prescribed by the pediatrician. CONCLUSION: Due to the currently high diagnostic suspicion of cows milk protein allergy in nurslings, other causes of these symptoms cant be neglected in the investigation when the elimination diet fails. In this nursling, the persistence of failure to thrive, apathy, anorexia and hypotonia during four months motivated the investigation that showed a severe hypercalcemia due to the usage of manipulated vitamin D.

Authors: Baldanza Patrícia , Cunha Eduarda , Hessel Gabriel , Brandão Maria Angela
Published: October 2023

This case report is intended to describe a rare case of splenic infarction (SI) associated with biliary atresia, which contributed to the worsening of the prognosis. In this case study, a boy diagnosed with biliary atresia underwent the Kasai procedure at the age of 3 months. The patient presented an intense abdominal pain, ascites and fever at the age of 6 years. A computed tomography (CT) scan showed enlargement of the spleen and an image suggestive of SI. The symptoms improved with the administration of antibiotics, analgesics, while ascites decreased with the use of diuretics. Liver transplantation was indicated. SI is an extremely rare event characterized by vessel occlusion, parenchymal ischemia and tissue necrosis. The symptoms are non-specific and may be confounding factors with other causes of acute abdominal pain. Splenomegaly-inducing diseases may be a risk factor. There are few case reports of SI and cirrhosis of different etiologies in childhood. Abdominal CT scan with intravenous contrast is the imaging modality of choice and the treatment ranges from supportive care to splenectomy. Despite being a rare condition, its knowledge is extremely important, as it allows early clinical suspicion, with immediate institution of treatment, which may interfere with the prognosis.

Cardiac arrhythmias are electrical alterations that may have varied clinical presentations according to their etiological origin, association with adjunct heart problems and degree of impairment of cardiac functioning. Therefore, the epidemiological profile of patients diagnosed with cardiac arrhythmia treated in a Pediatric Cardiology Outpatient Clinic was traced, identifying the most prevalent types of cardiac arrhythmias in these patients and also analyzed whether there are differences between the prevalence of types of arrhythmias in patients with heart disease and those with a structurally normal heart. The studied group comprises patients registered in the database of the Pediatric Cardiology Discipline, from January 1, 1996 to December 31, 2019. Their data were analyzed and subjected to appropriate statistical evaluation, considering a significance level of 5%. The variables analyzed were: Sex; Age; Type of Arrhythmia; Presence or not of Associated Heart Diseases. A total of 365 patients diagnosed with arrhythmia were evaluated, of which 15.9% had heart disease and 84.1% did not have heart disease. In patients with heart disease, there was no difference between the sexes, whereas in the group of patients without heart disease, there was a predominance of males. It was concluded that the most prevalent arrhythmias were atrial extrasystoles, ventricular extrasystoles and total atrioventricular block, considering both sexes. In females, the most prevalent were total atrioventricular block, atrial extrasystoles and ventricular extrasystoles. In males: ventricular extrasystoles, atrial extrasystoles and paroxysmal supraventricular tachycardia.

Authors: Koloskova O.A. , Ponomarenko E.V.
Published: October 2023

This article delves into the most prominent transformations of the English lexical system within the period of 2020-2023. These transformations, on the one hand, reflect the unprecedentedly rapid changes in today’s reality; on the other hand, they contribute to certain trend formation in the global public opinions and in a way stimulate social, political and economic processes due to information richness of the up-to-date media landscape, as well as the large-scale engagement of English speakers in global processes. The present research analyses the changes that have been taking place in the lexical system of English business discourse as illustrated by the top words/phrases and buzzwords of 2020-2023 selected by the Global Language Monitor portal, the leading British, American and Australian dictionaries, including business lexis attributed to the language system. The article provides a comparative analysis of buzzwords discourse parameters observed at two stages of the said time period, i.e. 2020-2021 and 2022-2023. Besides, the authors look into: - the new lexical units which have gained popularity at each of the two stages, - the buzzwords that were popular in 2020-2021 but got out of active use in 2022-2023, - the most productive word formation models of contemporary English. In conclusion the authors outline the main evolutionary trends in the English lexical system and the evidence of anglophones’ frame shifting tendencies within the four year period.

Authors:   Department of Finance, Risk Management and Banking, University of South Africa, South Africa, Ndou Adam
Published: October 2023

Purpose: The main aim of the study was to investigate the impact of parental financial socialisation on financial knowledge of young black African adults in rural and low-income area in South Africa. This study was guided by family financial socialisation theory which is cognisant of the various family characteristics, such as family size and socioeconomic status, as predictors of financial outcome through their association with family socialisation process. Design/methodology/approach: The study used quantitative approach and survey design. Primary data on parental financial socialisation was collected from structured questionnaires. A survey was carried out on 500 young black African adults in Fetakgomo Tubatse and Intsika Yethu municipalities. The research hypotheses were tested using structural equation modelling (SEM) analysis. Findings: The study found that parental financial behaviour, parental financial discussion, parental financial communication, and parental financial teaching had significant positive impact on financial knowledge. It is observed that parental financial communication had the strongest impact on financial knowledge. Parental financial monitoring had a significant negative impact on financial knowledge. Thus, the overall results showed that parental financial socialisation has an impact on financial knowledge of young black African adults in rural and low-income area in South Africa. Research limitations/implications: Due to the low levels of general literacy among the respondents, which negatively affected data collection; some young adults did not understand the questionnaire and withdrew from participating in the study. Furthermore, even though confidentiality and anonymity were guaranteed, respondents were reluctant to participate in the study. They feared exposing their financial position and displayed a lack of trust. Originality/value: The current study contributed to the body of knowledge differently to the previous studies because it focused on parental financial socialisation of young black African adults in rural and low-income area. There is no study which has been conducted on parental financial socialisation impact on financial knowledge in rural and low-income area in South Africa. This makes this study so important and warrant that it should be carried out to provide the much-needed results that could help to improve the level of financial knowledge of young black African adults.

Authors: Thamlim William , Dwi Mulyani Susi
Published: October 2023

The fundamental purpose of this research is to obtain empirical evidence about the influence of information asymmetry, Employee Stock Ownership Program (ESOP), and audit quality on the practice of earnings management using discretionary revenue components of manufacturing firms in Indonesia and examine the moderating effect of financial distress on these factors. Firms used as references are manufacturing companies in the basic materials, industrials, consumer non-cyclical, consumer cyclical, and healthcare pharmaceuticals sectors listed in the Indonesia Stock Exchange from 2019-2021. This study uses purposive sampling method with panel data moderation and obtains total of 546 sample data units. Based on the research conclusion, information asymmetry can trigger a higher risk of earnings management, while the existence of an ESOP and audit quality can be used to suppress earnings management. Financial distress itself has no direct effect on earnings management. Financial distress has not been proven to strengthen the positive influence of information asymmetry or weaken the negative influence of the ESOP. Meanwhile, the financial distress conditions can weaken the role of audit quality in an effort to minimize earnings management practices of the company.

Published: October 2023

The disclosure of sustainability reports based on GRI standards between countries has become a new trend in recent years. This is driven by various factors, such as increasing awareness of sustainability issues, increasing information demands from investors and other stakeholders, and increasing the number of sustainability reporting standards available. This study aims to determine the level of disclosure of sustainability reports in companies engaged in the basic materials and energy industry sector in developed countries (UK, Germany and France) and developing countries (Indonesia, Malaysia and Thailand). The content analysis method is used in this study to assess the content of sustainability reports or integrated company annual reports of 269 selected companies listed in the basic material and energy sectors of the stock exchanges of each country within the period 2019 to 2022. Based on the results of the analysis, it was concluded that the level of sustainability disclosure in accordance with GRI Standards in developed countries is higher than in developing countries for all sectors. In addition, it is also found that there are differences in the completeness of the presentation of sustainability topics where environmental topics are topics that are more fully presented in developed countries in all sectors than in developing countries which are more complete in presenting social topics in all sectors.

Published: October 2023

This study examines the effect of corporate social responsibility in terms of corporate responsibility to shareholders, employees, suppliers, customers and consumers, the environment, and society on corporate resilience during the Covid-19 crisis. Resilience has stability and flexibility dimensions. The focus of this research is on the flexibility dimension. This quantitative study used data from 2020 when the Covid-19 outbreak began in Indonesia. One hundred four non-financial companies listed on the Indonesia Stock Exchange were selected as samples for this study. The results showed that the company's responsibility to the environment and society positively affected corporate resilience. The company's responsibility to suppliers, customers, and consumers has a negative effect on corporate resilience. Meanwhile, the company's responsibility to shareholders and employees does not affect corporate resilience. The results show that not all aspects of corporate social responsibility affect corporate resilience during the first year of the Covid-19 crisis.
The transformation of meanings of the semantic space of a literary text under translation to a foreign language
Authors: Smirnova Dariya Leonidovna
Published: October 2023

The transformation of the semantic structure of a literary text under translation into a foreign language is inextricably linked with the transformation of conceptually significant meanings of this text. In order to establish the direction of changing the meanings that make up the paradigm of the key statements for this text, it is necessary to comprehensively study the paradigm of meanings arising in the translation text using a definitional analysis of key lexemes in the source language and the translation language and contextual analysis of the meaning-forming contexts of this text. In this connection, the subject of the study is the semantic structure of a key utterance in a polyphonic text. Particular attention is paid to the change in the volume of meanings formed during translation and the change in the actualization of meanings arising as the text is semantically unfolded. The scientific novelty lies in the material chosen for the study: the paper presents contexts from the translation of the novel by F.M. Dostoevsky "The Idiot", made by Eva M. Martin, published by Everyman's Library in 1914 and republished in 1916. Previously, this translation text was not used as a valuable source for obtaining new knowledge about the semantic structure of a literary text and its transformation during translation, in particular, the aspect concerning the functioning of text dominants at the aesthetic and linguistic level. The contexts given in the study give reason to believe that the paradigm of the meanings of the key sign is significantly narrowed in the translation text, which leads to flattening of conceptually significant meanings and violation of the basic properties of the polyphonic word.

Published: October 2023

The paper considers the problem of fuel residues in the commercial tank of the spent stage of the launch vehicle. The analysis of existing methods of passivation of fuel residues in tanks in spacecraft and spent stages of launch vehicles is carried out. Using the example of the hydrogen peroxide torus tank of the first stage of the Soyuz-2.1v launch vehicle, a method is proposed for blowing liquid fuel residues out of the tank by injecting a boost gas. Under the action of centrifugal forces, the hydrogen peroxide residues are distributed along the walls of the tank in the form of a liquid film. CFD modeling of tangential gas input into a torus tank with hydrogen peroxide residues was carried out. The dependences of the velocity of the liquid film on the gas input velocity are obtained.

This paper presents the results of calculating the heat exchange intensity of combustion products of various nonproject gaseous fuels using hydrogen, methane-hydrogen mixture (MHM) and thermochemical conversion gases as examples. To identify the possibility of energy utilization of generated gases in standard boiler units, a comparison with the combustion products of natural gas is carried out here. It is determined that the use of hydrogen or methane-hydrogen mixture will require either changes in the heating surface at a constant capacity, or its reduction due to changes in the thermal absorption.

Published: October 2023

Biosorbents based on available natural organic raw materials (sapropel, leaf litter, peat and peat sapropel) have been synthesized. The influence of the heat treatment temperature on the basic physicochemical and textural characteristics of the obtained materials is investigated. The relationship between the main properties of sorbents and the nature of the raw materials is established. The largest amount of oil and petroleum products is retained by samples obtained from peat (9.29 g/g), peat sapropel (5.24 g/g) and leaf litter (5.65 g/g), which are characterized by minimal ash content. The possibility of regeneration of used biosorbents for their reuse has been studied. It is shown that the obtained samples can be used as oil sorbents for at least three cycles with intermediate oxidative regeneration (450 ° C, air).

The Role of Generative Pre-trained Transformers (GPT) in Recreational Tourism: An Interview with ChatGPT
Authors: ÇOLAK Okan
Published: October 2023

This study explores the potential benefits of employing generative pre-trained transformers (GPTs) in recreational tourism, the difficulties that arise when implementing such technology, the impact it has on tourist behaviour, and the ways it can be utilised in recreational tourism management. The original aspect of the study is that it is the first to give detailed information about the use of GPT in recreational tourism. ChatGPT was used as an interviewer in the study. ChatGPT is a software application that utilizes the high-powered machine learning software called Generative Pre-trained Transformer (GPT-3), developed by the OpenAI organization. Six questions were posed on the ChatGPT query screen (https://chat.openai.com/chat). The interview queries were prepared with reference to the study by Fusté-Forné and Orea-Giner (2023). The question statements in this study on the use of GPT in gastronomy tourism were changed to recreational tourism. ChatGPT's replies were tabulated and presented descriptively. Inferences and suggestions were made in line with the answers given by ChatGPT. The study showed that using GPT technology in recreational-based tourism can offer better customer interaction, decision-making, and a personalized travel experience. ChatGPT underlined that new technologies continue to evolve, and recreational-based tourism will become more personalized, informative, and immersive, ultimately enhancing the overall travel experience, and contributing to the growth and sustainability of the tourism industry. ChatGPT also noted GPT models have the potential to shape and enhance the entire travel experience for tourists, from the initial planning stages to the actual trip itself. Although GPT makes significant contributions to recreational tourism management and recreational tourists, there are deficiencies in ethical, privacy, and authenticity concerns.

This paper aims to contribute to a better understanding of inflected infinitve in Classic Portuguese. In works such as Martins (2006) and Fiéis & Madeira (2014) we have observed that the distribution of inflected infinitives changed from Old to Modern Portuguese. Based on a corpus from an archive located in Braga district, with notarial texts from the XVII century (1650-1700), we will describe the use of inflected infinitives in infinitival complementation in this period, showing the conditions that allowed its widening to other contexts in Modern Portuguese.
Orações consecutivas finitas em Português Europeu: uma análise sintática
Authors: Brito Ana Maria , Matos Gabriela
Published: October 2023

In this paper we analyse antecedent and free consecutives. In consecutives with overt antecedents, we adopt the split degree hypothesis of Corver (1993, 1997a, b 2013), which has the advantage of separating determiner-like degree word and quantifier-like words. We also adopt Kennedy’s (1997, 1999) and Corver’s (2013) hypotheses that consecutive CPs are adjuncts that act as modifiers of a DegP, which form a unit with the degree/quantifying word at the level of LF. This analysis is extended to free consecutive clauses. We claim that in free consecutives the gradable expression is an elided constituent included in the sentence that contains the consecutive CP, whose content must be recovered by (an element of) the sentence to which it is paratactically related.
Branching-chain propagation of parahydrogen-derived nuclear spin order on a catalyst surface
Authors: Pokochueva Ekaterina V. , Burueva Dudari B. , Salnikov Oleg G. , Koptyug Igor V.
Published: October 2023

When a parahydrogen molecule dissociates on a surface of a heterogeneous catalyst (e.g., of a metal nanoparticle), the correlation of the nuclear spins initially inherited by the two surface H atoms may be shared with other surface hydrogens as they diffuse and combine with random H atoms to produce H2 molecules which subsequently dissociate. This branching-chain-type propagation of nuclear spin order leads to its gradual dilution but at the same time is accompanied by an increase in the number of H atoms that share nuclear spin order. These conclusions, confirmed by the spin density matrix calculations, may be relevant in the context of parahydrogen-induced polarization (PHIP) in heterogeneous hydrogenations catalyzed by supported metal catalysts, observation of which apparently contradicts the accepted non-pairwise mechanism of hydrogen addition to an unsaturated substrate over such catalysts. The potential consequences of the reported findings are discussed in the context of PHIP effects and beyond.

Authors: Prat Alvaro , Abdel Aty Hisham , Kamuntavicius Gintautas , Paquet Tanya , Norvaisas Povilas , Gasparotto Piero , Tal Roy
Published: October 2023

We propose HydraScreen, a deep-learning approach that aims to provide a framework for more robust machine-learning-accelerated drug discovery. HydraScreen utilizes a state-of-the-art 3D convolutional neural network, designed for the effective representation of molecular structures and interactions in protein-ligand binding. We design an end-to-end pipeline for high-throughput screening and lead optimization, targeting applications in structure-based drug design. We assess our approach using established public benchmarks based on the CASF 2016 core set, achieving top-tier results in affinity and pose prediction (Pearson's r = 0.86, RMSE = 1.15, Top-1 = 0.95). Furthermore, we present a novel interaction profiling approach to identify potential biases in the model and dataset to boost interpretability and support the unbiased nature of our method.

Data-driven approaches to identify geophysical signals have proven beneficial in high dimensional environments where model-driven methods fall short. GNSS offers a source of unsaturated ground motion observations that are the data currency of ground motion forecasting and rapid seismic hazard assessment and alerting. However, these GNSS-sourced signals are superposed onto hardware-, location- and time-dependent noise signatures influenced by the Earth’s atmosphere, low-cost or spaceborne oscillators, and complex radio frequency environments. Eschewing heuristic or physics based models for a data-driven approach in this context is a step forward in autonomous signal discrimination. However, the performance of a data-driven approach depends upon substantial representative samples with accurate classifications, and more complex algorithm architectures for deeper scientific insights compound this need. The existing catalogs of high-rate (≥1Hz) GNSS ground motions are relatively limited. In this work, we model and evaluate the probabilistic noise of GNSS velocity measurements over a hemispheric network. We generate stochastic noise time series to augment transferred low-noise strong motion signals from within 70 kilometers of strong events (≥ MW 5.0) from an existing inertial catalog. We leverage known signal and noise information to assess feature extraction strategies and quantify augmentation benefits. We find a classifier model trained on this expanded pseudo-synthetic catalog improves generalization compared to a model trained solely on a real-GNSS velocity catalog, and offers a framework for future enhanced data driven approaches.

El propósito fue demostrar la relación entre la identidad organizacional y las actitudes hacia la corrupción y además caracterizar estas variables según criterios socio demográficos. A una muestra aleatoria estratificada de 210 estudiantes de diferentes programas de estudio de ciencias sociales de una universidad pública peruana, se aplicaron la Escala de Identidad Organizacional (Orellana et al., 2014) y la Escala Actitudes Hacia la Corrupción (Orellana y Bossio, 2019). Se encontró que las actitudes hacia la corrupción se relacionan significativamente con la identidad organizacional (r = ,376**) así como entre sus dimensiones, excepto entre la identidad personal-actitud hacia el tráfico de influencias, la identidad corporativa-actitud hacia la colusión y la Identidad corporativa-actitud hacia el incumplimiento de normas. En suma, a mayor identidad organizacional, mayores actitudes contra la corrupción. Se debe mejorar la identidad organizacional en universitarios de ciencias sociales a fin de tener mejores actitudes en contra de la corrupción, así como realizar nuevas investigaciones en poblaciones de otras edades y sectores sociales, además de corroborar la relación de implicancia de estas variables.

Hipertensi merupakan penyakit sistem kardiovaskuler yang menyebabkan gangguan pada pembuluh darah yang mengakibatkan jantung bekerja lebih keras karena terhambatnya suplai oksigen dan nutrisi yang terbawa oleh darah ke jaringan tubuh yang membutuhkannya. Hipertensi memiliki tanda dan gejala tekanan darah sistolik ≥140mmHg dan/atau tekanan darah diastolik ≥90mmHg setelah pemeriksaan berulang dan seringkali disadari ketika telah terjadi komplikasi. Upaya yang dapat dilakukan sebagai pengobatan adalah dengan aromaterapi mawar dan hidroterapi rendaman kaki air hangat. Tujuan Penelitian untuk mengetahui efektivitas kombinasi aromaterapi dan hidroterapi dalam menurunkan tekanan darah pasien hipertensi. Jenis penelitian ini adalah Quasy Experimental Design dengan rancangan pre-post design with group control serta dengan simple random sampling. Jumlah sampel dalam penelitian ini 40 responden pasien hipertensi primer yang rutin berobat ke Puskesmas, tidak mengonsumsi alkohol dan tidak merokok. Hasil penelitian menunjukkan selisih rata-rata penurunan tekanan darah sistole pada kelompok kombinasi lebih efektif dari kelompok hanya minum obat sebesar 6,8mmHg, lebih tinggi dari kelompok aromaterapi sebesar 3,0mmHg serta lebih efektif dari kelompok hidroterapi sebesar 4,0mmHg. Rata rata penurunan tekanan darah diastolik pada kelompok kombinasi lebih efektif dari kelompok hanya minum obat sebesar 3,8mmHg, lebih efektif dari kelompok aromaterapi sebesar 1,9mmHg serta kelompok hidroterapi sebesar 3,0mmHg. Hasil pengujian menggunakan uji One Way ANOVA didapat nilai signifikansi 0,00

Non-communicable diseases (NCDs) are chronic diseases often not realized by sufferers and continue to experience a significant increase. They are the largest contributor to the cause of death in the world. NCDs also affect a person's susceptibility to exposure to coronavirus 19 (covid 19) and increase the severity of covid 19 sufferers. This study aimed to design a health application that the community can use for early detection of NCD risk factors, especially modifiable behavioral risk factors and metabolic risk factors. The application design method used the prototype method. Needs analysis and application trials were conducted at Sriwijaya University. A needs analysis was performed by conducting in-depth interviews with five students, three lecturers, three employees, a leadership of faculty, and ahead of the university's healthy campus program. User trial results are evaluated through Zoom and by filling out a questionnaire on Google Forms. The results of the needs analysis survey showed that most users want the design of an Android-based health application that assesses the risk of NCDs and recommendations for the results of risk assessment. In conclusion, an android-based health application has been designed to independently detect the risk of non-communicable diseases under the name DERI PTM. This application can be developed into an effective educational media for preventing and controlling non-communicable diseases in the community. It can be utilized as an information system (surveillance) of NCDs at Sriwijaya University.

Acne vulgaris is an inflammation that occurs in the pilosebaceous gland with a prevalence of 18-21 years affected adolescents. This study aimed to determine the relationship between consumption of whey protein and the incidence of acne vulgaris. The research design was a literature review by searching medical scientific articles. Over 7,408 articles were found when searching for "protein" and "acne vulgaris." The articles were sorted by relevant publication in the last five years. There were 2,179 pertinent articles, which were then excluded from book studies that read 581 articles. Then, articles were screened only for whey protein research in the form of milk, so the remaining 129 studies were continued by selecting only subjects—adolescents aged 18-21 years so that the remaining 20 relevant articles are summarized in this study. The literature review results show a significant relationship between protein consumption and the incidence of acne vulgaris. The increase in sebum production caused by high protein consumption is the main reason for this correlation. Research findings suggest that people who consume high amounts of whey protein are more likely to develop acne vulgaris. In conclusion, this study lost the importance of nutrition in the incidence of acne vulgaris, with whey protein consumption being a significant contributing factor. The findings of this study may benefit individuals who wish to prevent or treat acne vulgaris by making dietary changes. Further research is needed to determine the optimal amount of protein intake to minimize acne vulgaris.
The Challenges and Factors Influencing ICT Integration for EFL Teachers in China: A Systematic Review

Published: October 2023

The advantages of using information and communication technology (ICT) in English as a Foreign Language (EFL) teaching and learning have been well documented in research studies. The international trend and Chinese national policies on education both call for EFL teachers to effectively integrate ICT into their teaching. However, only a few studies have explored the challenges of ICT integration into EFL teaching, especially in China. This study draws data from four databases based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 checklist to ensure a comprehensive and rigorous analysis of the available literature. By synthesising and analysing the findings from the final selected 17 articles between 2019 and 2022, this study highlighted the research designs of the relevant studies on the use of ICT by EFL teachers in China, along with the two most important underlying theories (TPACK and TAM) associated with ICT integration. It also provides insights into the specific challenges and influencing factors that impact ICT integration in EFL teaching in the Chinese context. The findings reveal that EFL teachers’ ICT literacy and acceptance are influenced by many factors which are frequently classified into external and internal ones. The majority of the reviewed studies offered recommendations on how to use technology more effectively, apply ICT in EFL teaching, and create authentic teaching and learning environments. Additionally, the findings of this study offer suggestions for future research and teaching approaches, particularly for overcoming the challenges of ICT integration.
