EFFECTIVENESS OF POWERPOINT PRESENTATION ON VOCABULARY RETENTION OF EFL FIRST-YEAR STUDENTS’ READING COMPREHENSION

Vocabulary learning plays an important role in language learning. To many language learners, lack of vocabulary is one of the biggest obstacles that prevent them from mastering the language. Moreover, there have been a lot of studies conducted to find out the way to help language learners acquire and retain learned vocabulary. Among them, PowerPoint is suggested by many researchers as one good way to help learners learn vocabulary retention through reading comprehension. The purpose of this study was to investigate the effect of PowerPoint on vocabulary retention in reading comprehension of EFL (English as a Foreign Language) first-year students at Long An University of Economics and Industry (DLA), Long An Province, Vietnam. Besides, this study investigates learners’ attitudes towards the use of PowerPoint in learning vocabulary. The participants were 60 non-English major students at DLA. Two instruments were (1) the tests on English vocabulary, (2) the questionnaire on the participants’ attitudes towards the use of PowerPoint in teaching and learning vocabulary, were investigated. The results demonstrated a significant difference in learners’ vocabulary retention: the participants in the experimental group remembered vocabulary longer than those in the control group. The study showed that the learners had positive attitudes towards the use of PPT (PowerPoint Presentation) in learning vocabulary retention.  Article visualizations

ATGNN: Audio Tagging Graph Neural Network

Deep learning models such as CNNs and Transformers have achieved impressive performance for end-to-end audio tagging. Recent works have shown that despite stacking multiple layers, the receptive field of CNNs remains severely limited. Transformers on the other hand are able to map global context through self-attention, but treat the spectrogram as a sequence of patches which is not flexible enough to capture irregular audio objects. In this work, we treat the spectrogram in a more flexible way by considering it as graph structure and process it with a novel graph neural architecture called ATGNN. ATGNN not only combines the capability of CNNs with the global information sharing ability of Graph Neural Networks, but also maps semantic relationships between learnable class embeddings and corresponding spectrogram regions. We evaluate ATGNN on two audio tagging tasks, where it achieves 0.585 mAP on the FSD50K dataset and 0.335 mAP on the AudioSet-balanced dataset, achieving comparable results to Transformer based models with significantly lower number of learnable parameters

3-D numerical simulation of the tidal circulation in the Gulf of Tonkin, Vietnam

The purpose of this paper is to present 3-D numerical simulation of the tidal circulation in the Gulf of Tonkin. A sigma-coordinate system transformation is used to make possible a total fitting between the computing point-grid and the bottom topography as well as the free water surface. A turbulence-closure sub-model K-L which permits the parameterization of the turbulence mixing is also included. The studied domain, the whole Gulf of Tonkin, extends from the coastal zone of Quang-Ninh into Thua Thien Hue province and as far as Hai-Nam (China) island seawards. The model have been calibrated and verified by the observed data at six different stations for a three and seven-day periods. The results are in good agreement with the observed data. The kinetic energy distribution was considered

The Translational Regulation of Lipoprotein Lipase by Epinephrine Involves an RNA Binding Complex Including the Catalytic Subunit of Protein Kinase A

The balance of lipid flux in adipocytes is controlled by the opposing actions of lipolysis and lipogenesis, which are controlled primarily by hormone-sensitive lipase and lipoprotein lipase (LPL), respectively. Catecholamines stimulate adipocyte lipolysis through reversible phosphorylation of hormone-sensitive lipase, and simultaneously inhibit LPL activity. However, LPL regulation is complex and previous studies have described translational regulation of LPL in response to catecholamines because of an RNA-binding protein that interacts with the 3′-untranslated region of LPL mRNA. In this study, we identified several protein components of an LPL RNA binding complex. Using an LPL RNA affinity column, we identified two of the RNA-binding proteins as the catalytic (C) subunit of cAMP-dependent protein kinase (PKA), and A kinase anchoring protein (AKAP) 121/149, one of the PKA anchoring proteins, which has known RNA binding activity. To determine whether the C subunit was involved in LPL translation inhibition, the C subunit was depleted from the cytoplasmic extract of epinephrine-stimulated adipocytes by immunoprecipitation. This resulted in the loss of LPL translation inhibition activity of the extract, along with decreased RNA binding activity in a gel shift assay. To demonstrate the importance of the AKAPs, inhibition of PKA-AKAP binding with a peptide competitor (HT31) prevented epinephrine-mediated inhibition of LPL translation. C subunit kinase activity was necessary for LPL RNA binding and translation inhibition, suggesting that the phosphorylation of AKAP121/149 or other proteins was an important part of RNA binding complex formation. The hormonal activation of PKA results in the reversible phosphorylation of hormone-sensitive lipase, which is the primary mediator of adipocyte lipolysis. These studies demonstrate a dual role for PKA to simultaneously inhibit LPL-mediated lipogenesis through inhibition of LPL translation

STUDY ON LEARNING AUTONOMY STRATEGIES FOR ENGLISH SPEAKING SKILLS OF HIGH-QUALITY FIRST-YEAR STUDENTS, SCHOOL OF FOREIGN LANGUAGES, CAN THO UNIVERSITY, VIETNAM

This study examined the challenges of self-studying English-speaking skills for first-year English studies majors at Can Tho University. The study aimed to answer questions such as: What self-study strategies can first-year students majoring in high-quality English at School of Foreign Languages at Can Tho University apply to develop speaking skills? The target audience was 96 English studies majors who have studied speaking and listening at Can Tho University. A questionnaire and an interview with 13 students were used to collect data for this study. In order to support the quantitative data, a questionnaire was used, while an interview was used for the qualitative data. This study aimed to find out the difficulties encountered by students, thereby proposing solutions to overcome them and improve the quality of their learning autonomy or self-studying English-speaking skills.  Article visualizations
