THE INFLUENCE OF EXTENSIVE READING ON VOCABULARY RETENTION IN EFL LEARNERS AT DONG NAI TECHNOLOGY UNIVERSITY
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.

A POWER-EFFICIENT 180 Hz FSC-LCD WITH LIMITED BACKLIGHT SIGNAL RATIO FOR COLOR BREAKUP SUPPRESSION IN ELECTRIC VEHICLE HEAD-UP DISPLAYS
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
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.
