type: item
description: Background: Noni fruit (Morinda citrifolia) is widely used in tradiƟonal medicine for health support; however, quanƟtaƟve scienƟfic data on its acƟve consƟtuents remain limited. Previous studies have shown that flavonoids, polyphenols, coumarins, and scopoleƟn contribute to the biological acƟviƟes of Noni fruit, but their contents are strongly influenced by raw material origin, ripeness, and processing methods. The absence of quality and dosage standardizaƟon may affect therapeuƟc effecƟveness and safety. ObjecƟve: This study aimed to perform preliminary phytochemical screening, thin-layer chromatography (TLC), and quanƟtaƟve determinaƟon of total flavonoids, total polyphenols, and scopoleƟn in Noni fruit. Materials and methods: Noni fruits were collected from Mephydica Co., Ltd. The chemical composiƟon was evaluated using preliminary phytochemical screening and TLC. Total flavonoid content (TFC) and total polyphenol content (TPC) were determined using the aluminum chloride and Folin-Ciocalteu methods, respecƟvely. ScopoleƟn was quanƟfied by UV-Vis spectrophotometry. Results: Phytochemical screening revealed the presence of diverse bioacƟve compounds, including coumarins, saponins, and reducing agents. TLC analysis showed a chromatographic spot corresponding to the scopoleƟn reference standard. The TFC of the methanolic extract was 25.232 ± 0.023 mg QE/g dry extract, while the TPC was 6.413 ± 0.112 mg GAE/g dry extract. The scopoleƟn content was determined as 1.636 ± 0.05 mg/g dry extract. Conclusion: The study provides quanƟtaƟve data on flavonoids, polyphenols, and scopoleƟn in methanolic extracts of Noni fruit, supporƟng its tradiƟonal use and contribuƟng to quality standardizaƟon and future applied research.

A study on the association between social media use and stress levels in students at Can Tho University of Medicine and Pharmacy in 2025
type: item
description: Background: The rapid increase in social media use among university students has raised concerns about mental health, parƟcularly stress. ObjecƟve: This study aimed to determine the prevalence of stress and its associated factors related to social media use among students at Can Tho University of Medicine and Pharmacy in 2025. Material and method: A descripƟve cross-secƟonal study was conducted on 1,052 undergraduate and bridging program students during the 2024 - 2025 academic year. Data were collected using a self-administered quesƟonnaire, and stress levels were assessed using the validated Perceived Stress Scale (PSS-10). LogisƟc regression analysis was performed to idenƟfy staƟsƟcally significant associated factors. Results: The findings showed that 78.7% of students experienced stress, including 19.2% with mild, 42.0% with moderate, and 17.5% with severe levels. Female students were more likely to experience stress than males. Regular students had a 2.43-fold higher risk of stress compared to bridging students, while first and second-year students had a 1.5-fold higher risk than senior students. Single students were 2.08 Ɵmes more likely to experience stress than married students. Factors related to social media use associated with higher stress included starƟng use aŌer entering university (p = 0.042), using more than 6 hours per day (p = 0.009), using more than five applicaƟons (p = 0.039), and using social media before sleep (p < 0.001), during study (p = 0.004), during meals (p < 0.001) and in leisure Ɵme (p = 0.006). Conclusion: Stress is a prevalent mental health issue among health science students and is significantly influenced by individual and social media use behaviors.

Assessment of masticatory performance: Current methods and clinical applications
type: item
description: Background: Masticatory performance is a key indicator of oral function and the success of prosthodontic rehabilitation, particularly in paƟents with tooth loss. Reduced masƟcatory function can impair food comminution and negatively affect digestion and quality of life. Properly designed dental prostheses can restore masticatory efficiency by optimizing force distribution, enhancing food fragmentation, and improving coordination within the masticatory system, whereas poorly fitting prostheses may compromise function and comfort. Consequently, the assessment of masticatory performance has become an essential parameter in evaluating functional recovery following prosthetic treatment. Review context: MasƟcatory performance is defined as the degree of food comminution achieved under standardized conditions, distinct from masƟcatory efficiency, which refers to the number of chewing cycles required to reach a specific masƟcatory outcome. Current assessment methods include both subjective and objective approaches. Subjective methods rely on quesƟonnaires and self-reported measures to capture paƟents' perceived chewing ability, while objective methods quantitatively evaluate food comminution or mixing ability using standardized natural or artificial test foods. Common objective techniques include food comminution tests, two-colored gum or wax mixing tests, glucose dissolution analysis and gummy jellybased assessments. Conclusion: Given that no single method fully captures all dimensions of masticatory function, a combined use of subjective and objective assessments is recommended to provide a comprehensive evaluation in both clinical and research settings.

Cooling channel design for improving quality of injection plastic product
type: item
description: Injection molding is the most widely used technique for making the related plastic parts for consumer electronics goods with limited lifespans, like mobile phones, which are growing more and more popular. The molten plastic beads must be injected into a mold cavity, cooled, then part-formed and ejected. Filling, packing, cooling, and ejection are the four key steps in an injection molding process. The length of the molding cycle affects how economical the procedure is. The cooling step is the most crucial of the three since it controls how quickly are produced. Otherwise, cooling systems are important for the injection molding process in terms of productivity, quality, and mold-making costs. In this paper, three conformal cooling channel designs are proposed for obtaining uniform cooling over the molded parts. The research is conducted by using CAE software (MOLDEX 3D) to simulate the injection process and compare the results of three conformal cooling channel designs with molded part cooling by moldbase. All three designs show that warpage and cycle time improve significantly, helping to decrease cost and increase productivity. In which the combination of a conformal cooling channel outside and a baffle cooling channel significantly reduces the warpage.

The impact of service quality on customer satisfaction among generation Y: The case of fast food restaurants in Hanoi
type: item
description: Nowadays, the growth of the service sector has played an essential role in the world's economy. As a result of increasing income in developing countries, the "hollowing out effect" emphasizes economic activities converting from the agriculture and manufacturing sectors to service. Cooking a meal at home has become harder than planning an eating-out activity. In this busy modern world, customers tend to choose "eating out" when they do not have time to prepare a meal. Hence, the restaurant industry is thriving. As a result, better knowledge of perceived customer satisfaction with service quality in the region will bring various potential benefits for both markets and managers. This study aims to explore the impact of service quality on customer satisfaction among Generation Fast Foods in Hanoi. The study was carried out by surveying 181 individual customers who are Gen Y and have been using fast food services at fast food stores in Hanoi and using the SERVQUAL model with 5 independent variables: Tangibility, Responsiveness, Assurance, Reliability, and Empathy. The results of testing the hypotheses and models show that the relationship between the factors influencing the perception of service quality at the store is empathy, assurance, and reliability. Based on the research results obtained, several recommendations are made to help improve service quality, thereby attracting customers to use the service at the store.

Project management for start-up businesses in F&B industry: A case study for milk tea shop in Vietnam
type: item
description: Milk tea or Bubble tea is currently growing and becoming entirely developed. Through our investigation into how milk tea shops are constructed nowadays, we discovered that there are no precise plans for handling and building projects; instead, milk tea shops are merely created and controlled using manual solutions. Therefore, we utilize Work Breakdown Structure (WBS) to separate and organize work objects throughout the project scope to address this issue. WBS also aids in minimizing project risks and job-related variations with the person in charge of that activity. Moreover, we used Microsoft Project software to effectively plan, organize, and finish the construction of a milk tea establishment in compliance with the initial budget and schedule. By doing this, we can better understand how to design and manage a project and ensure its success.

type: item
description: Background: Acinetobacter baumannii represents a critical antimicrobial resistance challenge in Vietnamese healthcare settings, with carbapenem resistance rates reaching 55-90%. Traditional checkerboard methodology for evaluating antibiotic combinations requires substantial time and resources, limiting routine application in research settings. Objective: To develop a predictive model for the FIC index of meropenem-colistin combination based on MIC values. Methods: A cross-sectional analytical study on 61 carbapenem-resistant A. baumannii strains (6/2022 - 12/2022). MICs were determined by broth microdilution, and synergy was evaluated through FIC index. Eight regression models were compared using 80/20 train-test split with 5-fold cross-validation for stability assessment. Results: All strains were resistant to meropenem but intermediate to colistin. The combination showed synergy in 77% and additivity in 23%. A logarithmic model FIC = 0.649 - 0.155 × ln(Mero) - 0.227 × ln(Col) achieved high accuracy (R² = 0.554). The model demonstrated 95% sensitivity and 75% specificity for synergy prediction with an overall classification accuracy of 88.5%. Conclusion: This is the first study applying machine learning for quantitative FIC prediction. While offering potential research applications, clinical implementation requires extensive validation, given recent evidence against therapeutic efficacy of this combination.

type: item
description: Background: Cleistocalyx operculatus is a tradiƟonal medicinal plant widely consumed in Vietnam and known to contain various bioacƟve consƟtuents. However, comparaƟve data on the anƟbacterial acƟvity of its leaf essenƟal oil and solvent extracts remain limited. ObjecƟve: This study aimed to compare the anƟbacterial acƟvity of the essenƟal oil and different leaf extracts of C. operculatus against selected bacterial strains. Materials and methods: Dried leaves of C. operculatus were extracted by ultrasonic-assisted extracƟon using 50% ethanol, 70% ethanol, and disƟlled water. The total flavonoid content was determined using the UV-Vis spectrophotometric method. EssenƟal oil was obtained from fresh leaves by steam disƟllaƟon. AnƟbacterial acƟvity was evaluated against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Bacillus subƟlis ATCC 6633 using the agar diffusion method. Minimum inhibitory concentraƟon (MIC) values were determined by agar diluƟon. Results: The 70% ethanol extract showed the highest TFC (35.963 mg QE/g dry extract) and the strongest anƟbacterial acƟvity, parƟcularly against S. aureus (MIC 0.3125 mg/mL). The water extract exhibited moderate acƟvity, whereas the 50% ethanol extract showed limited effects. EssenƟal oil was acƟve only against Gram-posiƟve bacteria with MIC values of 0.50% against S. aureus and 1.00% against B. subƟlis Conclusion: The 70% ethanol extract demonstrated the greatest anƟbacterial potenƟal, while the leaf essenƟal oil exhibited selecƟve acƟvity against Gram-posiƟve bacteria. These findings support the potenƟal of C. operculatus leaves as a promising source of natural anƟbacterial agents for further invesƟgaƟon.

The flipped classroom approach to enhancing reading skills and engagement among first-year EFL students
type: item
description: This study invesƟgates the impact of the flipped classroom model on reading comprehension and classroom engagement among first-year non-English major university students. Grounded in learner-centered pedagogy and construcƟvist theory, the flipped approach provided students with access to instrucƟonal materials before class and opportuniƟes for interacƟve, task-based acƟviƟes during class. A mixed-methods design was adopted, combining reading comprehension tests with semi-structured interviews to capture both academic outcomes and le arner experiences. Findings revealed that although post-test scores were lower due to the increased difficulty of academic texts, students demonstrated higher moƟvaƟon, confidence, and engagement in classroom tasks. The flipped classroom was also perceived as enhancing collaboraƟon and independent learning by allowing students to come to class beƩer prepared and ready to parƟcipate acƟvely. Challenges remained in terms of self-paced study, parƟcularly Ɵme management and maintaining consistent preparaƟon. Overall, the results suggest that flipped instrucƟon can strengthen students' readiness for academic reading and foster higher levels of engagement and moƟvaƟon, provided that adequate support for self-regulated learning is incorporated.

Governance dimensions driving the urbanization-green growth nexus: Evidence from Asian economies
type: item
description: In the context of many Asian economies struggling to balance rapid urbanizaƟon with green growth objecƟves, governance emerges as a key factor shaping the development trajectory. This study examines the role of governance dimensions in influencing the relaƟonship between urbanizaƟon and green growth across 32 Asian countries from 1996 to 2021. Employing the two-step system GMM approach, the results indicate that urbanizaƟon iniƟally exerts a negaƟve effect on green growth; however, this effect turns posiƟve as governance improves. Among the governance indicators, control of corrupƟon exerts the strongest influence, followed by government effecƟveness, voice and accountability, and rule of law. In contrast, regulatory quality appears limited, as many environmental policies remain largely formalisƟc, while poliƟcal stability and security show no staƟsƟcally significant impact. Based on these findings, the study proposes several policy implicaƟons to strengthen governance quality in specific areas, thereby transforming urbanizaƟon into a driver of sustainable and inclusive green growth.

Applying role-play to foster language and cultural competence in East Asian language majors at Hong Bang International University
type: item
description: This study examines the effecƟveness of role-playing as a pedagogical approach for enhancing language proficiency and intercultural communicaƟve competence (ICC) among university students majoring in Japanese, Chinese, and Korean at Hong Bang InternaƟonal University. Grounded in experienƟal learning theory and intercultural competence frameworks, the research adopted a mixed-methods design involving 120 parƟcipants across the three language majors. QuanƟtaƟve data were collected through pre- and post-tests assessing speaking performance, while qualitaƟve data were obtained from surveys, semi-structured interviews, and classroom observaƟons to contextualize learning outcomes. The results indicate overall improvements in learners' oral fluency, grammaƟcal accuracy, and interacƟonal ability following the roleplaying intervenƟon, with varying degrees of gain across the three language majors. Japanese majors demonstrated comparaƟvely higher post-test gains, while Chinese and Korean majors also showed consistent improvement. In terms of intercultural communicaƟve competence, students exhibited enhanced aƫtudinal openness, interpreƟve skills, and behavioral adaptability. QualitaƟve findings further suggest that role-playing supported contextualized language use and increased learner engagement, although challenges related to vocabulary limitaƟons and performance anxiety remained. These findings highlight the pedagogical value of role-playing in fostering both linguisƟc development and intercultural awareness in foreign language educaƟon. The study contributes empirical evidence supporƟng the systemaƟc integraƟon of role-play acƟviƟes into language curricula, parƟcularly for high-context languages and mulƟlingual classroom contexts.

The impact of job autonomy and job analysis on turnover intention: An empirical study of the mediaƟng role of continuance commitment
type: item
description: This study examines the indirect effects of job autonomy and job analysis on turnover intenƟons through conƟnuance commitment, framed by Social Exchange Theory. A cross-secƟonal survey was conducted across mulƟple industries, and data were analyzed using ParƟal Least Squares Structural EquaƟon Modeling (PLSSEM). The results demonstrate that job analysis clarity posiƟvely predicts conƟnuance commitment (β = 0.377), while autonomy shows a slight negaƟve relaƟonship (β = -0.147). In turn, conƟnuance commitment significantly reduces turnover intenƟons (β = -0.418), explaining 17.5% of its variance. These findings suggest that clear job roles strengthen employees' raƟonal investment in the organizaƟon, whereas high autonomy may enhance percepƟons of external mobility. The study contributes theoreƟcally by extending Social Exchange Theory and Job CharacterisƟcs Theory to explain how job design influences not only affecƟve but also calculaƟve forms of commitment. PracƟcally, the findings highlight that organizaƟons can improve retenƟon by providing role clarity and structuring autonomy in ways that develop job-specific experƟse and increase employees' perceived value of staying.

An automated assessment system for data structures and algorithms with diverse question types and knowledge-driven evaluation
type: item
description: This paper proposes an automated assessment system for Data Structures and Algorithms (DSA) that supports eight diverse quesƟon types-MulƟple-Choice QuesƟons (MCQ), Fill-in-the-Blank Number (FN), Fillin-the-Blank Number Sequence (FNS), Fill-in-the-Blank Programming Syntax (FPS), Fill-in-the-Blank Short String (FSS), Fill-in-the-Blank Expression/Formula (FE), Matching Pairs (MP), and Programming Exercises (PE)-across seven difficulty levels (Easy to Expert). Leveraging Bloom's Taxonomy and psychometric parameters (difficulty: p, discriminaƟon: d), the system uses knowledge matrices to integrate Course Learning Outcomes (CLOs), six content chapters, and cogniƟve levels, enabling adapƟve test generaƟon for quizzes, midterms, and exams. Automated scoring employs exact matching for MCQ/MP/FN/FNS, paƩern matching for FPS/FSS, symbolic evaluaƟon for FE, and test-case evaluaƟon for PE. The system tracks knowledge progression across tests, per topic, and per CLO, providing comprehensive feedback. IniƟal implementaƟons have shown the system's ability to improve assessment quality, decrease grading efforts, and facilitate data-driven teaching approaches in technical fields such as DSA.
