INNOVATIVE STRATEGIES TO IMPROVE ENGLISH SPEAKING SKILLS OF ECONOMICS UNDERGRADUATES
type: item
description: Developing English speaking skills is essential for economics undergraduates, as effective oral communication in English strengthens academic performance and enhances employability in an increasingly globalized business environment. However, many students in Vietnam continue to struggle with limited vocabulary, low confidence, and insufficient opportunities for authentic speaking practice. This study investigates innovative strategies to improve English speaking competence among economics majors in a Vietnamese university context. Using mixed-methods design, quantitative surveys measured students’ self-perceived speaking proficiency, while qualitative interviews with instructors identified key barriers and effective pedagogical approaches. The findings suggest that the integrated instructional approach may contribute to improvements in students’ fluency, accuracy, and communicative confidence. Furthermore, creating a supportive classroom atmosphere and offering consistent, constructive feedback help sustain long-term improvement. The proposed strategies address both linguistic limitations and broader skill requirements, aligning with the need to equip future economists with strong communication and professional competencies. These findings contribute to the development of practical and scalable strategies for curriculum design, teaching methodology, and technology integration, offering valuable implications for English language instruction in higher education, particularly for non-English-major students in economics-related disciplines.

THE INFLUENCE OF EXTENSIVE READING ON VOCABULARY RETENTION IN EFL LEARNERS AT DONG NAI TECHNOLOGY UNIVERSITY
type: item
description: This study looks into the impact of extensive reading on vocabulary retention among English as a Foreign Language (EFL) students at Dong Nai Technology University. A total of 137 non-English major students took part in an eight-week extensive reading program that included graded books and self-selected online reading resources. A pre- and post-test design assessed vocabulary retention, while reflective journals and a post-treatment questionnaire explored students' perceptions of extensive reading. Quantitative data were analysed using paired-sample t-tests, while qualitative responses were thematically investigated. The findings show a significant improvement in students' vocabulary retention after prolonged reading exposure, which is consistent with meta-analytic data indicating extended reading promotes vocabulary learning in EFL contexts (Saito & Webb, 2020; Yamashita, 2013). Furthermore, the students reported improved motivation and confidence in acquiring new vocabulary through contextualised reading, which supports previous research that suggests repetition and context are critical for long-term vocabulary retention (Thongsan, 2023; Waring & Takaki, 2003). These findings confirm the usefulness of extended reading as an effective instructional method in EFL environments, implying that prolonged reading activities should be included in university English programmes to improve vocabulary development. The pedagogical implications and directions for future research are discussed.

IMPACTS OF CLIMATE CHANGE ON VIETNAM’S AGRICULTURAL SUPPLY CHAIN: CURRENT CHALLENGES AND SUSTAINABLE ADAPTATION ORIENTATIONS
type: item
description: Climate change is posing increasingly serious challenges to agriculture and agricultural supply chains in Vietnam, as evidenced by extreme weather events, droughts, salinity intrusion, and growing risks of logistics disruptions. This study aims to examine the impacts of climate change on the key stages of agricultural supply chains, including production, harvesting and storage, logistics and transportation, processing and distribution, and end markets . It also analyzes the vulnerability and adaptive capacity of stakeholders involved in these supply chains. The study employs a qualitative approach based on semi-structured in-depth interviews with farmers, cooperatives, procurement and processing enterprises, logistics providers, and local authorities in regions highly affected by climate change during the period 2020 - 2025. These primary data are complemented by secondary data collected from relevant reports and previous studies. The findings indicate that extreme climatic conditions - such as storms, droughts, salinity intrusion, and rising temperatures increases - not only reduce agricultural productivity but also disrupt transportation, increase post-harvest losses and processing costs, and ultimately undermine the stability of agricultural supply chains. Smallholder farmers and small- and medium-sized enterprises are identified as the most vulnerable actors due to limited resources and risk management capacity. Based on these findings, the study proposes several adaptation strategies from a supply chain perspective, including the promotion of climate-smart agriculture, the adoption of technology in production and logistics, improved risk management, and stronger supply chain linkages to enhance the resilience of Vietnam’s agricultural system in the face of climate change.

A POWER-EFFICIENT 180 Hz FSC-LCD WITH LIMITED BACKLIGHT SIGNAL RATIO FOR COLOR BREAKUP SUPPRESSION IN ELECTRIC VEHICLE HEAD-UP DISPLAYS
type: item
description: This paper proposes a power-efficient field-sequential color (FSC) liquid crystal display (LCD) system designed to enhance head-up display (HUD) performance in electric vehicles (EVs) by effectively suppressing of color breakup (CBU). Conventional FSC-LCDs, although they offer higher optical throughput by eliminating color filters, are prone to noticeable CBU artifacts under motion. To overcome this, we propose a 180Hz FSC-LCD architecture combined with a Limited Backlight Signal Ratio (LBSR) method. The technique embeds red and blue signal components into a green-dominant first field while regulating their intensity through carefully optimized signal coefficients. This configuration maintains high image fidelity, reduces perceptual artifacts, and avoids the need for high-refresh-rate displays or local-dimming backlights. Simulation tests using dynamic camera movement to mimic saccadic eye motion demonstrate that the proposed system achieves imperceptible CBU levels, with ΔE color errors below 3.0 and green desaturation minimized to under 5%. Compared to conventional 240Hz stencil-FSC systems, the 180Hz LBSR approach reduces power consumption by up to 25% while simplifying hardware design through the use of a global-dimming backlight. These results validate the system's suitability for compact, cost-effective, and energy-conscious HUD applications in next-generation electric vehicles.

OPTIMIZATION OF THE FERMENTATION PROCESS FOR BANANA (Musa spp.) – ROSELLE (HIBISCUS SABDARIFFA L.) WINE AT LABORATORY SCALE
type: item
description: This study was carried out to explore suitable fermentation conditions for producing wine from a mixture of bananas (Musa spp.) and Roselle (Hibiscus sabdariffa L.) flowers at the laboratory scale. The response surface methodology (RSM) using a Box–Behnken design was applied to examine the influence of initial total soluble solids (TSS) concentration (18–22 °Brix), yeast inoculation ratio (1–3% v/v), and fermentation time (120–168 hours) on the residual reducing sugar content and alcohol concentration in the final product. The most appropriate set of conditions was identified as 20 °Brix initial TSS, a yeast inoculation ratio of 2.48% (v/v), and a fermentation time of 152.1 hours, yielding a wine containing 9.86% (v/v) ethanol and 13.09 g/L reducing sugar. The yeast inoculation ratio and fermentation time showed clear effects on sugar utilization and alcohol production. The product underwent sensory assessment and routine quality analysis, both indicating satisfactory results. These outcomes suggest that combining bananas with Hibiscus sabdariffa L. may be a promising approach for developing a new tropical fruit wine with potential commercial and nutritional value. Future work could extend to larger-scale experiments, long-term stability evaluation, and tracking changes in bioactive compounds during fermentation.

THE IMPACT OF TASK-BASED LANGUAGE TEACHING ON NON-ENGLISH MAJORED STUDENTS’ SPEAKING PERFORMANCE - A CASE STUDY AT DONG NAI TECHNOLOGY UNIVERSITY
type: item
description: This study investigates the effect of Task-Based Language Teaching (TBLT) on English as a Foreign Language (EFL) students' speaking performance at Dong Nai Technology University. In the 2025 academic year, a total of 162 non–English majored students participated in this case study. The participants were divided into two groups: an experimental group that received training via TBLT, and a control group that was taught using traditional teacher-centered methods. In particular, this method was based on the Presentation–Practice–Production (PPP) model, which required students to generate language in a restricted number of form-focused tasks after teachers introduced linguistic structures and directed them through controlled practice. Speaking tasks in this approach typically prioritized repetition and accuracy over communicative meaning. Therefore, to assess speaking performance, data were collected through pre- and post-tests, as well as classroom observations. The results revealed that students in the experimental group outperformed their classmates in speaking performance, particularly fluency and communicative competence. The findings suggest that TBLT is an effective approach to enhancing EFL learners’ speaking performance in higher education. Incorporating task-based activities into English classes’ increases learner engagement, supports autonomy, and improves communication-related learning outcomes.

BIOSYNTHESIS OF SILVER NANOPARTICLES FROM (Vitex Negundo L.) LEAF EXTRACT AND PRELIMINARY EVALUATION OF THEIR ANTIOXIDANT ACTIVITY
type: item
description: In the present investigation, silver nanoparticles (AgNPs) were biosynthesized employing the leaf extract of Vitex negundo L., as a reducing as well as a stabilizing agent. The formation of AgNPs was evidenced by a color transition from yellow to dark brown and further corroborated by a characteristic surface plasmon resonance absorption band at 442 nm in the UV–Vis spectrum. Morphological and dimensional analyses conducted via scanning electron microscopy (SEM) revealed predominantly monodisperse, spherical nanoparticles with an average diameter ranging from 10 to 40 nm. The antioxidant potential of the synthesized AgNPs was quantitatively assessed using the 2,2- diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The results indicated a concentration-dependent enhancement in radical quenching activity, with the AgNPs exhibiting an EC₅₀ value of 0.53 mg/mL, in comparison to 0.65 mg/mL for the leaf extract, thereby demonstrating markedly superior antioxidant efficacy. The results demonstrated that AgNPs synthesized from Vitex negundo leaf not only possess stable nanoscale characteristics but also exhibit pronounced bioactivity, particularly antioxidant capacity, underscoring their promising applicability in biomedical, pharmaceutical, and cosmeceutical domains.

description: This paper examines the organization and operation of the lay judge (saiban-in) system within the context of Japan's judicial reform, adopting a regional studies perspective. Utilizing research methods such as synthesis, content analysis, and logical reasoning, the paper describes the current organizational state of Japan's lay judge model through several key aspects: legal regulations, activities in criminal trials, and independence in adjudication. The lay judge system demonstrates several advantages, including: enhancing public trust in the judicial system, mandatory involvement of lay judges in serious cases, and the requirement for lay judge consensus in judicial decisions. However, the lay judge system also presents certain limitations. Based on these findings, the paper offers some insights derived from Japan's experience regarding mechanisms for public participation in judicial activities within the judicial system. Subsequently, this paper derives key insights applicable to Vietnam's context, with the objective of enhancing the existing framework for public participation within the judicial system.
