Published: July 2023

With the development of recommendation systems, large amount of information collected from e-commerce could help customers to find the potential interesting products. Collaborative filtering and content-based recommendation systems are two common recommendation systems. While collaborative filtering has the problem of cold-start, content-based recommendation system could not explore the potential interests of users. Hybrid system combining these two techniques could achieve better results. This paper applies hybrid recommendation methods to the Amazon food reviews and evaluate the results in the aspects of precision, recall, diversity and novelty. It is found that the weighted hybrid recommendation system combing 0.95 weight of collaborative filtering and 0.05 content-based recommendation system achieves a good precision and diversity.
Modeling dengue transmission in Singapore
Authors: Niu Te
Published: July 2023

Dengue fever is a widespread epidemic that transmits between the vector mosquitoes and the host humans. It has long remained a threat to the public health for many countries since there is no effective treatment for it currently. Therefore, it is practically valuable to conduct research on the transmission of Dengue Fever virus to help combat Dengue Virus. Out of this purpose and to bridge the gap in the research of Dengue Fever, this paper took use of parameters such as susceptible humans and carrier humans to construct a differential equations model that reasonably depicts the host-to-vector and vector-to-host transmission of Dengue Fever Virus. Especially, in this model, by computing out the spectral radius of the matrix FV^(-1) at the disease-free equilibrium (DFE) point, we could get the basic reproductive number of the dengue fever virus, which is of great practical importance (where the detailed interpretation of notation F and V will be given in the second chapter in this paper). Besides, we conducted empirical analysis with the data of cases of Dengue Fever in Singapore at the year of 2019 to show that our method is valid in the real world. Also, we made an extensive prediction with the data of 2022.

Depression is a major disorder that causes an insistent feeling of sadness which affects the thinking and behaviour of the person that leads to variety of emotional and physical problems. Early detection of depression is most important since it is associated with sui-cide and it is also the main cause for somatic diseases. In recent days, people are freely conveying what they think directly through any of the social media. In the proposed re-search work, machine learning, deep learning and hybrid learning approaches are utilized to perform sentiment analysis in order to determine a person's indicators of sadness from their social media postings. All of the aforementioned models use English language social media postings from the shared task introduced by ACL 2022 and categories depression signs into three groups such as not depressed, moderately depressed and severely de-pressed. The experimental results show that among all the machine learning, deep learning and hybrid learning techniques, CNN-LSTM model obtained highest precision of 0.93 for moderate depressed and severe depression categories.
Improving transfer ability of adversarial sample based on adversarial transformation
Authors: Song Changlin
Published: July 2023

In recent years, Deep neural networks (DNN) have caused a huge sensation, showing outstanding capabilities in the fields of computer vision tasks and natural language processing. It has been gradually discovered that DNN are easily disturbed by adversarial samples, which are formed by superimposing the original samples and tiny perturbations. Although these tiny perturbations are imperceptible to the naked eye, they can significantly interfere with the model output. In security-related fields, adversarial examples bring huge hidden dangers to the deployment of DNN systems. When testing and evaluating DNN systems, researchers usually study the robustness of deep neural networks using transfer-based attacks, which are black-box attacks using carefully crafted adversarial examples from the source model. Adversarial samples with strong transfer ability are more aggressive to black-box models, so how to improve the transfer ability of adversarial samples has attracted the attention of many scholars. Since the existing methods based on adversarial transformation to improve the transfer ability of adversarial samples are more complicated to train and cost to attack, this paper uses a cycle-consistent generative adversarial network to implement adversarial transformation, which reduces the attack cost and training cost. At the same time, our extensive experiments on the CIFAR series datasets verify the superiority of this generation method in improving the transfer ability.

This study evaluated the knowledge, attitude, and practice (KAP) regarding complementary feeding (weaning) among mothers with six-month-old children. A quantitative, cross-sectional, descriptive-analytical approach was employed, emphasizing the gathering, analysis, and interpretation of relevant data to portray the phenomenon accurately. The evaluation was divided into three KAP domains. A total of 200 respondents were included in the analysis. It was discovered that mothers demonstrated concerns and a lack of knowledge about enriching complementary food with iodized salt (Knowledge: M = 2.63 out of 5, SD = 1.454, Score = 52.6%). Attitude-wise, mothers reported initiating complementary feeding due to a perceived insufficiency of breast milk (Attitude: M = 1.60 out of 5, SD = 0.802, Score = 32.0%). However, mothers understood complementary feeding practices well (Practice: M = 49.68 out of 60, SD = 8.8, Score = 82.8%). Despite some awareness about sensitive health aspects such as food allergies, mothers lacked crucial knowledge regarding the enrichment of complementary food with iodized salt and iron-rich food. Mothers' decisions to initiate complementary feeding were largely driven by concerns about the sufficiency of their milk production. The study underlines the need for prenatal guidance and education for parents on desirable practices concerning complementary food.

Published: July 2023

Introduction:

Social media use has exploded in popularity over the past decade with over 1.5 billion users on Facebook and 320 million users on Twitter. The aim of this study was to analyze the use of social media by orthopaedic journals and determine whether a relationship exists between social media followers and journal impact factor.

Methods:

The Clarivate Analytics Impact Factor tool was used to identify all orthopaedic journals with a 2022 impact factor of greater than 1.5. We then conducted a query on Instagram, Twitter, LinkedIn, and Facebook to determine which programs had pages on each platform.

Results:

Seventeen journals were included across all orthopaedic subspecialties. Of the 17 journals, 14 (82.4%) had a Facebook page, eight (47%) had an Instagram page, 15 (88.2%) had a Twitter account, and 8 (47%) had a LinkedIn profile. When compiling the number of followers by social media platform, Twitter had the most (177,543), followed by Facebook (149,388), Instagram (81,739), and LinkedIn (77,459). We found a significant correlation between the number of social media followers and journal impact factor (Pearson correlation coefficient [PCC] = 0.67; P = 0.003). When analyzing each social media platform independently, we found a significant correlation between the number of Facebook and Twitter followers and journal impact factor (PCC = 0.54; P = 0.02 and PCC = 0.80; P < 0.001, respectively).

Discussion:

We have shown a notable association between the number of social media followers and a journal's impact factor. With the increasing shift toward online distribution, orthopaedic journals may use our data when evaluating their social media strategy to maintain and potentially increase their exposure and potentially their impact factor.

Published: July 2023

This present work is to investigate the antibacterial activity of CeO2 nanoparticles on five foodborne pathogens. Low-temperature solid-state reactions were used to create co-doped CeO2 nanoparticles (Co-CeO2 NPs). In the current work, the impact of Co-doping on polycrystalline CeO2 samples synthesized using the co-precipitation method at room temperature for Co-doping concentrations of 0.5%, 1%, 3%, and 5% is discussed. Rietveld refinement of the X-ray diffraction patterns confirms that the Co-doped CeO2 samples have a face-centred cubic structure. This shows that the Co ions have been successfully integrated into the CeO2 lattice. Also, the UV-Vis-NIR absorption spectra confirm that redshifts do happen in the Co-doped CeO2 samples, which shows that the band gap energy decreases as the number of Co ions grows. In an antibacterial test against five pathogenic microbes, S. aureus, M. luteus, Enterobacter aerogenes, S. typhi, and Pseudomonas aeruginosa, Co-doped cerium oxide nanoparticles significantly slowed the growth of all five pathogens, both in liquid and solid growth conditions. These results show that Co-doped CeO2 nanoparticles have strong antibacterial properties against foodborne pathogens. This suggests that they could be used as promising bionanomaterials for in vivo therapeutic uses.

Published: July 2023

Görsel kültür, görsel imajların yaygın olarak kullanıldığı bir kültürel ortamı ifade ederken, post-truth ise hakikatin ikincil planda kaldığı bir döneme işaret etmektedir. Bu makalede, görsel kültür ve post-truth kavramı arasındaki ilişkiler ve etkileşimler ele alınacak ve bu iki kavramın birbirini nasıl etkilediği incelenecektir. Post-truth kavramsal olarak, duygusal etkilerin ve kişisel inançların objektif gerçeklerin önüne geçtiği bir durumu tanımlamaktadır. Bu kavram, görsel kültürle yakından ilişkilidir çünkü görsel imgeler, duygusal tepkileri tetikleyebilir ve gerçeklik algısını manipüle etmeye neden olabilmektedir. Görsel kültür, medya aracılığıyla yayılan görsel imgelerle post-truth fenomeninin güçlenmesini bereberinde getirmektedir. Görsellerin kolaylıkla paylaşılması ve viral hale gelmesi, yanlış bilgilerin ve manipülatif görsellerin hızla yayılmasına ve toplumun gerçeklik algısını sarsmasına neden olabilir.

First Peoples' perspectives on successful engagement at university: What keeps students coming back to Indigenous education units?
Authors: Cook Becki , Whatman Susan , Sammel Alison
Published: July 2023

In this article, we present a case study of the nature of First Peoples’ engagement with the GUMURRII Student Success Unit at Griffith University, Queensland, Australia. Higher education plays a critical role in improving socioeconomic outcomes in First Peoples communities. Recent reports indicate First Peoples are still under-represented at university, with lower participation and higher attrition rates than non-Indigenous students. Previous studies indicate that engagement with Indigenous education units (IEU) improves student progression, retention and success; however, the specific nature of engagement with IEUs from the students’ perspectives has not been widely examined. We address a gap within the literature, seeking to better understand how support services are being contemporarily utilised by First Peoples students. By utilising an Indigenist research design, we offer an interpretation of the lived experiences of First Peoples students to better understand their reasons for engagement with IEUs, and to explore the impact upon their ongoing participation and outcomes in higher education. The findings contribute to broader understandings of the role of IEUs in higher education and illustrate that students engage with them for reasons that extend far beyond traditional tertiary support.

Arturo en Saor. La literatura artúrica gallega a inicios del siglo XXI: pervivencia, renovación, agotamiento
Authors: Gutiérrez García Santiago
Published: July 2023

La literatura artúrica comienza a cultivarse en Galicia a inicios del siglo XX, asociada al mito del origen celta del pueblo gallego. Su vinculación con dicho mito y con la ideología nacionalista ha determinado su evolución hasta la actualidad y ha dificultado los intentos de renovarla. El presente trabajo analiza las actitudes de los principales escritores gallegos que han compuesto narrativa artúrica, mostrando su adscripción dispar a los presupuestos del mito celta y su creciente empleo de la intertextualidad. Desde finales del siglo XX se ha hecho evidente la consolidación de una tradición artúrica gallega propia, cuyos fundamentos ideológicos están siendo cuestionados en los últimos años. El presente artículo analiza la crisis reciente de la literatura artúrica gallega y sus causas. Acaso el más decisivo se origine en el proceso de normalización e institucionalización de la literatura gallega, que ha permitido una mayor autonomía discursiva a sus textos literarios y el surgimiento de nuevos discursos sociales, como el feminismo, que reclaman su presencia en los textos y que incluso cuestionan la figura del rey Arturo.
Medievalismo afectivo en A rainha morta e o rei saudade, de António Cândido Franco
Authors: Machado Ana Maria
Published: July 2023

Partiendo del concepto de medievalismo afectivo formulado por Thomas Prendergast y Stephanie Trigg (2018), en la novela A rainha morta e o rei saudade, de António Cândido Franco (2013), exploramos las semejanzas en el modo en que el deseo medieval y el contemporáneo determinan la constitución del pasado, analizamos la hermenéutica de la empatía que subyace en la novela y en ella perpetúa y reinventa el gesto memorial de Pedro y su propia mitificación de la historia. El medievalismo afectivo del escritor constituye una práctica transformadora, estructurada según las coordenadas temporales, culturales y afectivas del autor. En la rememoración del pasado se prolonga la memoria petrina, que Franco exacerba y convierte en mito genesíaco, materializando el imaginario de un tiempo anterior en un futuro que lo mira como mito fundador. Para demostrarlo, considero algunas diferencias entre dos versiones (la primera, de 1990) de esta historia de amor para señalar las reelaboraciones imaginativas de la novela de 2003 y la afinidad de los episodios maravillosos, la recomposición del nuevo dispositivo narrativo y sus repercusiones en la mitificación de la saudade. Más que una idea de la Edad Media, A rainha morta e o rei saudade pone de relieve una idealización del amor. Anclado en la armonía de una mirada glorificadora -de Pedro, sobre su pasado de amor, y del autor, en el ejercicio de memoria que exacerba la memoria petrista medieval-, y de amor por ese pasado, el autor escenifica la obsesión que lo vincula a los amores de Pedro e Inés. Los revisita sin disimular hasta qué punto el resultado final refleja también el devenir del autor empírico.
The Role of Social Media in Academic Motivation and Engagement: A Case Study of Undergraduate Students in Vitenam
Authors:   National Academy of Public Administration, Vietnam, Trang Nguyen Thi Quynh
Published: July 2023

This study examines the impact of social media on academic motivation and engagement among undergraduate students in Vietnam. Regression analysis reveals that motivation, engagement, and study habits influence students’ use of social networks for learning. Motivation shows a positive and significant relationship with media use, supporting previous research emphasizing its role in academic success. Social media platforms facilitate peer connections, information sharing, and participation in discussions, enhancing student motivation. Engagement also exhibits a positive association with social media use, highlighting its importance in leveraging these platforms for learning. Furthermore, study habits demonstrate a positive link with social media use, indicating that effective habits contribute to academic success and the utilization of social media for educational purposes. Importantly, this study does not find evidence of negative effects associated with social networks, although they can distract from academic pursuits when used non-academically. These findings underscore the significance of motivation, engagement, and study habits in effectively harnessing social networks for educational purposes, providing insights for educational practitioners and policymakers in promoting positive technology integration in learning environments.

Authors: THONGSAI Nichaphat , CHUIDUANG Aphinya , KLADSOMBOON Sumana , IN Insik , PAOPRASERT Peerasak
Published: July 2023

Herein, carbon dots (CDs) as biocompatible, fluorescent carbon-based nanomaterials were synthesized from papaya seed waste as renewable carbon sources for the first time via a facile acid pyrolysis method. The papaya seed-derived CDs showed blue fluorescence emission under UV light (365 nm) with a quantum yield of 2.74%, and contained oxygen-, and nitrogen- containing functional groups. Due to their surface functionality, the CDs have a great potential for using as fluorescence sensing probe in metal ion sensing application. The CD solution exhibited the most selective detection to Cu2+ as presented the highest fluorescence quenching with the limit of detection (LOD) of 5.16 μM. The CD-paper-based fluorescent sensor was also developed for practical application, and the RGB value was used to compare the sensitivity of CDs toward metal ions. The CD sensing film was also prepared for diethyl ether vapor sensing via optical electronic nose system. The principal component analysis (PCA) score plots revealed the total variance of 99.3%, indicating that the CDs can be used to discriminate different concentrations of diethyl ether/ethanol vapor mixtures. This work demonstrated that the papaya seed-derived CDs have a great attention to be alternative materials for developing sensing materials in both solution and film forms.

Published: July 2023

BACKGROUND: P1041 was a randomised, placebo-controlled isoniazid prophylaxis trial in South Africa. We studied predictors for TB in HIV-exposed children participating in the P1041 trial.METHODS: We included data from entry until Week 108. Predictors considered were
type of housing, overcrowding, age, sex, ethnicity, tobacco exposure, weight-for-age percentile Z-score (WAZ), CD4%, viral load (VL), antiretroviral therapy (ART) and number of household smokers.RESULTS: Of 543 HIV-positive (HIV+) and 808 HIV-exposed uninfected (HEU) infants
at entry, median age was 96 days (interquartile range: 92–105). Of 1,351 caregivers, 125 (9%) had a smoking history, and 62/1,351 reported current smoking. In 594/1,351 (44%) households, there was at least one smoker. Smoking caregivers consumed 1–5 cigarettes daily. In the HIV+
cohort, significant baseline TB predictors after adjusting covariates were as follows: WAZ (adjusted hazard ratio [aHR] 0.76, P = 0.002) and log10 HIV RNA copies/ml (aHR 1.50, P = 0.009). Higher CD4% (aHR 0.88, P = 0.002) and ART (aHR 0.50, P = 0.006)
were protective. In the HEU cohort, smoking exposure was associated with reduced TB-free survival on univariate analysis, but not after adjustment in the multivariate model.CONCLUSION: Low WAZ and high VL were strong predictors of TB disease or death. Rising CD4 percentage and being

BACKGROUND: Obstructive sleep apnoea (OSA) patients have a decreased exercise capacity. Potential cardiovascular capacity in patients with OSA with different severity without known cardiovascular disease has not been described.OBJECTIVE: To evaluate impaired potential
exercise cardiovascular capacity during cardiopulmonary exercise testing (CPET) in OSA patients and to compare cardiovascular performance reaction with different severity during graded exercise stages.DESIGN: All participants were accompanied without cardiovascular disease, especially
hypertension and arrhythmia. Parameters of different stages were compared between subjects with and without OSA, and among OSA patients with varied severity.RESULTS: Despite having significantly higher peak exercise diastolic blood pressure (DBP) and ventilatory equivalent for CO2
(EQCO2), patients with OSA had a lower peak oxygen uptake (VO2), heart rate (HR), heart rate recovery (HRR) and respiratory reserve (BR) than normal subjects. Furthermore, significant correlations were found between VO2, DBP, EQCO2, HRR, BR
and the apnoea-hypopnea index. In severe OSA, there was a greater difference in HR and HRR during the anaerobic threshold stages.CONCLUSIONS: OSA patients demonstrate reduced potential cardiovascular capacity, even without documented cardiovascular disease. Patients with severe
OSA develop impaired exercise capacity at early stage during exercise. These data point to exaggerated haemodynamic response to graded exercise and delayed post-exercise cardiovascular response recovery in OSA patients. CPET can be a supplement for assessment of OSA severity.

SETTING: According to reports in South Africa, treatment failure rates for rifampicin-resistant TB (RR-TB) are significant and below the WHO target of ≥70%. HIV infection and the use of highly active antiretroviral therapy (HAART) influence how patients receiving anti-TB drugs
respond to therapy. In the treatment of RR-TB, more recent medications, including bedaquiline, pretomanid and linezolid (BPaL), have shown promising results.OBJECTIVE: To assess treatment outcomes in RR-TB patients using BPaL and other second-line anti-TB drugs as recommended by
the WHO in the South African population.DESIGN: The databases Medline, PubMed, Google Scholar and Embase were searched for studies between 2015 and 2022, which investigated BPaL outcomes in South Africa.RESULTS: Of the 27,259 participants, 21% were on bedaquiline, 1%
were taking pretomanid and 9% were taking linezolid as part of their background regimen. About 68% of the patients were HIV-positive, with 59% of them taking HAART.CONCLUSION: Overall, 66% of patients taking BPaL drugs as part of their background regimen had favourable treatment
outcomes. Additionally, patients with RR-TB who were HIV-positive and taking HAART while receiving BPaL drugs as part of a background regimen had improved treatment outcomes.

BACKGROUND: These clinical standards aim to provide guidance for diagnosis, treatment, and management of drug-susceptible TB in children and adolescents.METHODS: Fifty-two global experts in paediatric TB participated in a Delphi consensus process. After eight rounds
of revisions, 51/52 (98%) participants endorsed the final document.RESULTS: Eight standards were identified: Standard 1, Age and developmental stage are critical considerations in the assessment and management of TB; Standard 2, Children and adolescents with symptoms and signs of
TB disease should undergo prompt evaluation, and diagnosis and treatment initiation should not depend on microbiological confirmation; Standard 3, Treatment initiation is particularly urgent in children and adolescents with presumptive TB meningitis and disseminated (miliary) TB; Standard
4, Children and adolescents should be treated with an appropriate weight-based regimen; Standard 5, Treating TB infection (TBI) is important to prevent disease; Standard 6, Children and adolescents should receive home-based/community-based treatment support whenever possible; Standard 7, Children,
adolescents, and their families should be provided age-appropriate support to optimise engagement in care and clinical outcomes; and Standard 8, Case reporting and contact tracing should be conducted for each child and adolescent.CONCLUSION: These consensus-based clinical standards,
which should be adapted to local contexts, will improve the care of children and adolescents affected by TB.

CONTEXTE : Médecins Sans Frontières Belgique a mis en place des diagnostics au point de service (DPS) pour le dépistage précoce d’un VIH avancé, et en présence de celle-ci, d’une TB et d’une cryptococcose, dans
six centres de santé (Kasai, St Ambroise, St Joseph, Libondi, Lisanga et Kimia) à Kinshasa, République Démocratique du Congo (RDC).OBJECTIF : Documenter leur contribution dans le diagnostic de ces affections.MÉTHODE : Ceci
est une étude transversale rétrospective sur des adolescents et adultes VIH-positif, admis avec suspicion d’un VIH avancé. Une comparaison 2 ans avant et 2 ans après installation des DPS a été réalisée.RÉSULTATS :
Au total, 745 et 887 patients étaient retenus respectivement avant et après l’installation des DPS. L’âge moyen était de 39,7 ans (déviation standard [DS] 12,04); 66% (n = 1 077) étaient des femmes. Les patients avec CD4 dosés
étaient passés de 40,3% (n = 300) à 64,4% (n = 573) (P < 0,001). Après l’installation des DPS, ils variaient entre 47,8% (Lisanga) et 97,1% (Kasai). La proportion d’infection à VIH avancé était comparable
(n = 158, 52,7% vs. n = 288, 50,3%; P = 0,779). Chez les patients avec un VIH avancé, la TB était dépistée chez 28,5% (n = 82), dont 41,5% (n = 34) de confirmation; la cryptococcose était dépistée chez 24,7%
(n = 71), dont 9,9% (n = 7) de confirmation. Des disparités entre les centres étaient observés.CONCLUSION : Les DPS ont augmenté l’accès des patients au dosage des CD4 et au diagnostic d’un VIH avancé dans
les six centres dans la RDC. Cependant des actions sont requises pour améliorer cette performance, y compris le dépistage de la TB et de la cryptococcose.

Published: July 2023

No presente estudo, bibliográfico-documental e de abordagem qualitativa, em que se fez uma revisão de literatura do tipo integrativa, buscou-se refletir sobre o processo ensino e aprendizagem e suas possibilidades para o desenvolvimento cognitivo da criança. Para tanto, levantou-se a seguinte questão norteadora: quais as possibilidades do processo de ensino e aprendizagem contribuir para o desenvolvimento cognitivo da criança? A busca dos dados foi realizada nas bases de dados Literatura Latino-American e do Caribe em Ciências da Saúde (LILACS) e o Centro de Recursos Educacionais (ERIC). Como palavras – chave, utilizou-se, respectivamente: Ensino; Educação Infantil; Métodos de Ensino; Aprendizagem Infantil. Nesta investigação, buscou-se aprofundar estudos sobre a dinâmica do processo de ensinar e aprender na Educação Infantil tendo como foco diferentes aspectos, desde profissionais envolvidos, assim como a própria concepção de educar as crianças para além do “cuidar” e do “brincar”, bem como sua relação com o seu desenvolvimento cognitivo. Os resultados apontaram para o necessário rompimento de perspectivas funcionalistas, alertando para a importância do lúdico como elemento da cultura e, por assim ser, demonstra a sua relevância e relação com o processo ensino e aprendizagem a partir de uma intencionalidade do(a) professor(a), propiciando espaços que estimulem a espontaneidade, a liberdade de ação e a ludicidade de forma descontraída engajadora nos diferentes momentos da aula. Assim, os estudos e pesquisas analisados sinalizam para uma estreita relação entre o processo ensino e aprendizagem com o desenvolvimento cognitivo da criança a partir da ludicidade, em especial, o brincar.

Published: July 2023

O Ensino de Saúde nas aulas de Ciências é um desafio para a garantia de uma aprendizagem efetiva, transformadora de atitudes de vida e propositiva de hábitos saudáveis. Proporcionar melhor conhecimento sobre o funcionamento do corpo, das características das doenças e de hábitos de higiene, podem, contudo, ser insuficientes para que os alunos desenvolvam e mantenham comportamentos saudáveis. Assim, esta proposta pedagógica tem como objetivo ajudar os professores de Ciências a orientar os alunos do ensino fundamental sobre a importância da prática da higiene bucal no cotidiano, estimulando o interesse na saúde da dentição e da boca, além de apresentar-lhes os Objetivos de desenvolvimento Sustentável (ODS). O Brasil ainda apresenta elevada incidência de problemas relacionados à saúde bucal e difícil acesso a serviços odontológicos, portanto, esta proposta pedagógica visa instrumentalizar professores do ensino fundamental para orientar os alunos sobre a importância da saúde bucal, do bem-estar em geral e dos ODS.
