    INTRODUCTION: National surveillance data in Malaysia has observed a marked reduction in the number of new HIV cases among people who inject drugs (PWID) in the past decade. This study sought to estimate the current prevalence and associated risk factors of HIV and hepatitis C virus (HCV) among PWID in suburban areas of Klang Valley, Malaysia.

    METHODS: Between September 2021 and March 2022, a cross-sectional, respondent-driven sampling survey was conducted. Participants completed rapid HIV and HCV testing as well as social and behavioural assessments. Factors associated with HIV- and HCV-positive results were estimated using logistic regression.

    RESULTS: Four-hundred individuals were recruited in the study, of whom 382 (94%) were men. The prevalence of HIV and HCV was 5.5% (95% confidence interval [95% CI]: 3.6-8.3) and 40.5% (95% CI: 35.7-45.5), respectively. Current heroin and amphetamine-type stimulant (ATS) use, regardless of injection or non-injection use, were reported by 340 (85.0%) and 328 (82.0%) individuals, respectively. Past exposure to the criminal justice system (lock-ups, prison and compulsory drug detention centres) was associated with both HIV (Adjusted odds ratio [aOR] = 3.47, 95% CI: 1.33-10.2) and HCV (aOR = 3.32, 95% CI: 2.06-5.39)-positive results. Additionally, HIV-positive results were associated with current ATS use (aOR = 0.31, 95% CI: 0.12-0.86). Meanwhile, HCV-positive results were associated with current heroin use (aOR = 2.44, 95% CI: 1.16-5.48), lifetime enrolment in methadone treatment (aOR = 2.30, 95% CI: 1.23-4.27), current methadone treatment (aOR = 0.46, 95% CI: 0.23-0.92) and current mixing of drugs through injection use (aOR = 1.80, 95% CI: 1.08-3.03).

    CONCLUSIONS: This study observed low HIV prevalence among PWID, primarily associated with ATS use, while HCV prevalence, linked to heroin use, remained high. Higher odds of being HCV positive among PWID who reported to have ever but not currently enrolled in methadone programmes indicate that treatment may not be continuous once initiated, potentially due to exposure to the criminal justice system. These findings underscore the need for a dual approach: enhanced harm reduction programmes for PWID and a legal reform to address potential barriers posed by criminalization.

    Student engagement is a malleable behavior shaped by instructional environments and widely regarded as a key component of higher education quality. Nevertheless, many college students have inadequate positive experiences with physical education classes, characterized by a lack of engagement. Therefore, framed within the self-determination theory and social cognitive theory, the present empirical research investigates how autonomy, relatedness, and competence support are associated with student engagement during physical education learning, focusing on the mediating variables of autonomous motivation and self-efficacy. Data collection involved a cross-sectional survey administered to undergraduates from four colleges located in Jiangxi Province, China. After excluding invalid questionnaires, 406 eligible responses were included in the data analysis. Structural equation modelling was then constructed through AMOS 26.0 for hypothesis testing. According to the findings, teacher autonomy and relatedness support were significantly related to student engagement, while competence support showed no significant correlation. Additionally, the pathways from autonomy and competence support to student engagement were both mediated by autonomous motivation. However, its mediating role was not supported in the link between relatedness support and student engagement. Furthermore, teacher autonomy, competence, and relatedness support all significantly influence student engagement via self-efficacy. The present study explores the relational mechanisms linking teacher support to student engagement in college physical education. These results contribute to refining teaching strategies to enhance student engagement while providing insights into optimally motivating instruction in higher education physical education teaching.

    The increased popularity of smartphone-based human activity recognition (HAR) in recent decades has been driven by its low computational requirements and user privacy protection. Yet, developing a reliable smartphone-based HAR still presents several challenges. For example, handcrafted feature-based approaches highly depend on laborious feature engineering/selection techniques that require human intervention. Implementing conventional Convolutional Neural Networks may result in unsatisfactory performance in time series classification as they cannot effectively extract time-dependent features. Although recurrent models excel at extracting temporal information, they require extensive computational resources to attain high performance, limiting their practicality for real-time applications. Thus, we propose a lightweight smartphone-based HAR architecture called Lightweight Parallel Temporal Network (Light-PTNet) for reliable classification. Light-PTNet comprises parallelly organised Light Spatial-Temporal Heads (LSTC Heads) that capture underlying patterns at various scales of the inertial signals. These heads utilise dilations and residual connections to preserve longer-term dependencies without increasing the model parameters. This work assesses the proposed Light-PTNet's performance on open-access HAR datasets: UCI HAR, WISDM V1, and UniMiB SHAR, following a user-independent protocol. The results reveal that our proposed Light-PTNet achieves 98.03% accuracy on UCI HAR, 81.58% on UniMiB SHAR and 97.02% on WISDM V1 with fewer model parameters (lower than 0.1 million parameters).

    BACKGROUND/PURPOSE: Human umbilical cord mesenchymal stem cell secretome (HUCMSCS) and nanoemulsion propolis (NEP) from Tetragonula biroi may be beneficial regenerative medicine to reduce LPS-induced osteolysis with hyperglycemia. This study aimed to investigate the HUCMSCS and NEP effect on nuclear factor associated T-cell-1 (NFATc1), sclerostin, receptor activator kappa beta (RANK), its ligand (RANKL), the osteoprotegerin (OPG) expression, tartrate-resistant acid phosphatase (TRAPase), and cathepsin K (Ctsk) serum level in LPS-induced osteolysis in hyperglycemic Wistar rats (Rattus novergicus).

    MATERIALS AND METHODS: Twenty-eight healthy male Wistar rats, 1-2 months old and 250-300 g body weight, were divided into seven groups, namely K1: control group; K2: 100 μl LPS; K3: hyperglycemia (≥230 mg/dL); K4: 100 μl LPS with hyperglycemia; K5: LPS, hyperglycemia, and 100 μl NEP; K6: LPS, hyperglycemia, and 100 μl HUCMSCS; and K7: LPS, hyperglycemia, and 100 μl HUCMSCS and NEP. Escherichia coli`s LPS was used to induce osteolysis on the calvaria. NEP and HUCMSCS were formulated and collected, then injected subcutaneously on the calvaria. Hyperglycemia-induced streptozotocin 30 mg/kg injection for one week, intraperitoneally. All samples were sacrificed on day 8. Blood samples were collected to examine TRAP and Ctsk levels with enzyme-linked immunosorbent assay. NFATc1, sclerostin, and RANK-RANKL-OPG expression investigated with immunohistochemistry.

    RESULTS: HUCMSCS and NEP administration inhibit TRAP and Ctsk levels, reduce NFATc1, sclerostin, and RANK-RANKL, but enhance OPG expression in LPS-induced osteolysis with hyperglycemia with significant differences between groups (P ≤ 0.05).

    CONCLUSION: HUCMSCS and NEP post-administration reduced osteoclastogenesis in LPS-induced osteolysis calvaria with hyperglycemic in rats in the early phase of bone remodelling.

    AIM: To review the relationship between drug concentrations of perioperative intravenous lidocaine and their analgesic effects.

    METHODS: We systematically searched SCOPUS, Medline, EMBASE, CENTRAL, and Web of Science (inception to March 2024) for randomized controlled trials comparing intraoperative lidocaine to placebo or control in adults undergoing non-cardiac surgery. Studies reported pain outcomes and plasma lidocaine concentrations. Bias was assessed using the Cochrane risk-of-bias tool, and data was analyzed with a random-effects model to determine mean difference (MD) and 95% confidence intervals (CI).

    RESULTS: Fifteen studies (445 lidocaine, 453 control patients) were included. Lidocaine lowered post-anesthetic care unit (PACU) opioid use (8 studies, MD: -3.00, 95% CI [-5.00, -1.01], p = 0.0092, I2 = 57%), with meta-regression indicating greater reduction at higher plasma concentrations (regression coefficient: -3.05, 95% CI [-4.48, -1.61], p = 0.002). However, 11 studies found no significant difference in 24-hour postoperative opioid consumption or pain scores. Nausea and vomiting incidence were similar between groups, and a few patients experienced lidocaine-related adverse events.

    CONCLUSION: Perioperative lidocaine infusion reduces PACU opioid consumption, with greater effects at higher concentrations, although significant heterogeneity was noted. Further research is needed to identify optimal concentrations for clinically significant analgesic benefits.

    BACKGROUND: Instability core training (ICT) has been the focus of extensive research because of its proven benefits to athletes' core muscle strength and sprint performance. However, there is a lack of systematic reviews explicitly evaluating the impact of instability core training (ICT) vs traditional core training (TCT) on athletes' trunk strength and sprint performance. This study aims to conduct a systematic review and meta-analysis of the effects of ICT vs TCT on trunk strength and sprint performance among athletes.

    METHOD: This study used guidelines for the systematic review and meta-analysis of PRISMA, Web of Science, EBSCOhost (SPORTDiscus), PubMed, Scopus, CNKI, and Google Scholar to collect original references in electronic databases. The Population, Intervention, Comparison, Outcome, and Study Design (PICOS) method was selected for the inclusion criteria. The physiotherapy evidence database (PEDro) scale was used to assess the scoring for articles' risk of bias. The scoring of 12 studies ranges from 5-7 (out of 11 points), and study quality is moderate to high.

    RESULTS: Out of 285 identified studies, only 12 articles fulfilled all the eligibility criteria after screening. ICT could significantly improve trunk strength and sprint performance among various athlete populations using unstable surfaces or environments (i.e., BOSU ball, Swiss ball, wobble boards, suspension trainer, Sissel pillows, inflated disc, foam surface, Airex balance pad, Togu power ball, thera-band, elastic band and so on) than TCT using stable surfaces or environments (i.e., floor and bench). In addition, the ICT vs TCT intervention showed a moderate to large effect size (ES = -0.40-1.86; all p < 0.05) in improving trunk muscle strength and sprint performance.

    CONCLUSION: The finding suggests that different types of ICT benefit athletes, as this training method can effectively enhance trunk strength and sprint performance in athletes than TCT. Therefore, this study suggests that ICT should be considered in athletes' daily training routines for trunk strength and sprint performance.

    Diabetes Mellitus (DM)- Type 2 is increasingly prevalent in today's population. DM remains poorly controlled due to insufficient knowledge and understanding of this disease. Maintaining good diabetic self-care requires knowledge and empowerment. The COVID-19 pandemic had caused a shift of some public attention from non-communicable to communicable diseases, leading to patients becoming ignorant of their diabetic status. Therefore, we aim to develop an online education video platform that enables patients to enhance their knowledge about Diabetes Mellitus Type 2. In this blocked randomised control trial, a minimum number of 232 participants with type 2 diabetes mellitus will be needed. Patients will consent and voluntarily participate during their follow-up at public primary health care clinic (Klinik Keshihatan Cheras Baru). Patients undergoing diabetic follow-up will be divided into two groups where only patients within the intervention group will receive diabetic care video. Patients' clinical profiles such as date of birth, gender, education status, Diabetes Knowledge Test (DKT) and Diabetic Empowerment Scale (DES-28) were collected to assess diabetes self-care knowledge and empowerment using self-administered questionnaires. Patients will be reminded to complete the educational video at the 3-month and 6-month follow-ups, and the aforementioned parameters will be reassessed. The data will be assessed using an independent t-test for the difference between intervention and control groups. A Paired t-test will assess the difference between the patient pre and post-intervention after 6 months. A generalised Estimating Equation will be used to investigate the effectiveness of diabetes knowledge and clinical outcome, adjusted with covariates. P

    Social media has become an essential part of international students' daily lives. As the world becomes increasingly globalized and communication and transportation systems rapidly develop, the number of international students is growing remarkably. Consequently, the influence of social media on the psychological adaptation of international students has become a matter of concern. However, the relationship between these two factors remains inconclusive. Moreover, there is a scarcity of studies investigating the influence of social media use motivations on the psychological adaptation of international students. Previous research has evidenced that the relationship is indirect, but limited studies have identified psychological mechanisms such as acculturation orientations. Therefore, this study aims to identify the mediating role of acculturation orientations (Malaysian and Chinese cultural orientations) in the relationship between social media use motivations (information seeking, social, and entertainment motivations) and the psychological adaptation of Chinese students in Malaysia. An online survey was administered, employing the convenience sampling technique to collect data from a sample of Chinese international students in Malaysia. A total of 438 questionnaires were analysed by using SPSS and AMOS software. The results demonstrated that three types of use motivations can help Chinese students improve their psychological adaptation in Malaysia, while entertainment motivations have the greatest influence. Likewise, acculturation orientations also benefited psychological adaptation, with mainstream orientations having a stronger contribution. Furthermore, this study reported an indirect mechanism whereby information seeking and social motivations influenced psychological adaptation through Malaysian and Chinese cultural orientations. The findings suggested that Chinese students can use social media purposefully to obtain a better psychological adaptation in Malaysia. Besides, social media designers can enhance the functions and services of social media to provide more support for international students. Relevant departments and educators in Malaysia should appreciate the role of social media and acculturation orientations in helping international students have a better overseas experience and enhance Malaysia's competitiveness in the international education market.

    OBJECTIVES: In order to explore the influence mechanism of family environment on the prosocial behavior tendency of college students and the chain mediating role of empathy and moral sensitivity in this relationship.

    METHODS: A survey was conducted on 451 college students using the Family Adaptability and Cohesion scales, the Dispositional Moral Sensitivity Questionnaire, the Prosocial Tendencies Measure and the Chinese Version of the Interpersonal Reactivity Index-C.

    RESULTS: The results showed that empathy and moral sensitivity significantly mediate the effect of family environment on college students' prosocial behavior tendency. This is manifested in three mediation paths: the mediating role of empathy (with 28.57% of the mediating effect), the mediating role of moral sensitivity (with 61.90% of the mediating effect), and the chain mediating role of empathy and moral sensitivity (with 9.53% of the mediating effect).

    CONCLUSIONS: The study reveals the mechanism by which family environment affects college students' prosocial behavior, which provides some theoretical guidance and practical inspiration for cultivating college students' prosocial behavior.

    Children with cerebral palsy (CP) often struggle to participate in traditional language assessments due to their limited mobility, making it challenging for speech-language therapists (SLTs) to accurately assess their language abilities. In recent years, there has been evidence that eye-tracking is an effective way of measuring the receptive language abilities of children who demonstrate difficulties with traditional language assessments. This study aimed to (i) develop eye-tracking assessment materials based on a receptive vocabulary subtest of a Malay language assessment and (ii) evaluate the performance of children with CP on the receptive vocabulary assessment conducted via eye-tracking, compared to their performance on a traditional receptive vocabulary assessment. The first phase of the study focused on developing eye-tracking receptive vocabulary assessment materials from the Malay Preschool Language Assessment Tool and trialling the materials and assessment protocol. This phase involved 15 typically developing children aged 4-6 years. The finalized materials and protocol were administered to 15 children with CP in the second phase. Each child attended two assessment sessions: the first was a traditional receptive vocabulary assessment, and the second utilized eye-tracking technology. Children practiced eye-tracking through online games. Results showed that eight children with CP performed better in the eye-tracking assessment, two scored similarly across both methods, and five scored lower during eye-tracking. The Wilcoxon Signed Rank Test conducted revealed no significant difference in scores across both assessment methods (p > .05). Furthermore, most children exhibited poor consistency in their scores across the two methods. These findings suggest that while some children with CP may benefit from receptive vocabulary assessments conducted via eye-tracking, no single assessment method is optimal for all children with CP. Instead, children with CP may benefit from a combination of assessment methods, including eye-tracking, to increase the accuracy of assessment results.

    BACKGROUND: The concept of deprescribing is gaining traction among clinicians as a formalized approach to improving medication safety for older persons. It has been found to be safe and effective in reducing medication burden. However, its implementation remains challenging. Most research has been conducted in high-income countries, with limited prospective data on deprescribing outcomes in outpatient care settings for older adults in low- and middle-income countries (LMICs). Therefore, evaluating local deprescribing interventions is essential to produce evidence on their effectiveness in older populations. Our study aimed to assess the effectiveness of the Physician-Pharmacist Partnership Intervention for Deprescribing (P3ID) among older persons attending a falls and syncope clinic.

    METHODS: This randomised controlled trial will be conducted at a teaching hospital in Kuala Lumpur, Malaysia. Participants will involve individuals aged ≥60 years with at least one chronic disease requiring pharmacological treatment, attending the falls and syncope clinic with ≥1 potentially inappropriate medication (PIM) undergoing systematic multidomain assessment and attending physicians at the clinic. The joint pharmacist-physician intervention comprises five steps: 1) PIM identification, 2) decision on cessation and prioritisation, 3) medication withdrawal, 4) monitoring and support, 5) and documentation.

    CONCLUSION: The P3ID trial tests the hypothesis that a jointly led pharmacist-physician intervention in an outpatient will reduce the total number of medications, improve medication adherence, reduce falls and improve patients' and doctors' satisfaction towards pharmacist services. Findings from this study would inform future deprescribing practices, particularly in LMIC, pertaining to fall prevention as well as aid the development of future deprescribing interventions in other settings.

    This study investigated the effects of task complexity, task difficulty, and critical thinking disposition on college students' writing performance. 201 participants were selected via probability sampling. Each completed three writing tasks of varying complexity, resulting in a corpus of 603 compositions. A follow-up questionnaire assessed task difficulty and critical thinking disposition. Results showed that both task complexity and difficulty significantly affected writing performance. Specifically, four sub-constructs of critical thinking disposition (analyticity, systematicity, inquisitiveness, and cognitive maturity) were positively associated with writing performance and mediated the relationship between task difficulty and writing performance. Structural and mediation models were established using Smart PLS to illustrate these relationships. This study contributes to the growing field of cognitive-oriented and affective-related research by exploring the cognitive and affective factors influencing writing and provides practical recommendations for writing assessment and pedagogy.

    INTRODUCTION: The global population is projected to double by 2050 with most older adults expressing preference to age in place. Despite this demographic shift, indoor mobility challenges which directly impact independence, safety and quality of life remains poorly understudied, creating a critical knowledge gap for effective intervention development.

    METHODS: A systematic literature search was conducted on four databases from inception to September 2024. Inclusion criteria included: (1) participants aged 60 years and above; (2) were primary data on self-reported indoor mobility challenges; and (3) published in English language. Two reviewers independently performed data abstraction, evaluated the risk-of-bias and quality of included article using the NewCastle Ottawa Scale for cross-sectional or Joanna Briggs Institute Checklist for qualitative studies. Thematic synthesis with constant comparison analysis identified key mobility constraint factors.

    RESULTS: Nine studies encompassing 1,833 participants were identified. Older adults reported four main indoor mobility challenges: fatigability, poor balance, home environmental barriers, reduced strength and limb weakness. These limitations contributed to reduced endurance, even in indoor settings. The presence of various health conditions further compromised their mobility and ability to age in place healthily.

    CONCLUSION: To support ageing in place, a comprehensive environmental assessments and home modifications can be considered. Multi-stakeholder collaborations are needed to support the independence, safety, and quality of life of older adults who wish to age in place. Further research is warranted in suburban and rural areas to explore socioeconomic factors and determinants of indoor mobility.

    There is a growing emphasis on developing Quality Physical Education (QPE) programs. However, a research gap exists due to the lack of measurement instruments to assess QPE for students. This study aimed to develop an instrument to assess QPE implementation and its validity and reliability in China. This study comprised three phases. In Phase 1, a conceptual framework for QPE was established using grounded theory based on interviews with 22 PE teachers and 20 students. In Phase 2, using the conceptual framework from Phase 1, we developed an item pool supported by a literature review, expert evaluations, and student interviews. In Phase 3, a cross-sectional study was conducted with secondary school students (705 participants) to analyse the items and assess the instrument's reliability and validity through exploratory and confirmatory factor analysis, as well as test-retest analysis. The final 45-item instrument, comprising four subscales (student, family, school, and community) across 10 factors, demonstrated strong validity and reliability. Model fit indices met established thresholds (e.g., CFI and TLI ≥ .90, as well as RMSEA ≤ .08). The composite reliability and average variance extracted values for each factor exceeded.7 and.5, respectively, with the test-retest reliability also exceeding.7, indicating high reliability and validity. This study addresses a critical methodological gap in QPE research by developing a culturally contextualized assessment instrument that explicitly identifies and measures students' perceptions of QPE implementation. This instrument enables systematic monitoring of QPE practices from students' perspectives, informing evidence-based policymaking and resource allocation. Integrating student, family, school, and community subscales supports holistic interventions to improve the quality of PE.

    The study investigates the relationship between high school accessibility and enrollment rates in urban and rural areas within a county. The main goal is to explore how spatial accessibility to high schools impacts student enrollment opportunities, particularly in the context of urban-rural disparities. Using empirical analysis, the study evaluates the effects of transportation infrastructure, school distribution, and government policies on educational access and fairness. The findings reveal, there is no significant correlation between high school accessibility and enrollment rates in both urban and rural areas. Furthermore, the research shows that improvements in rural infrastructure and policies have helped mitigate potential disparities, leading to a more balanced educational landscape. This study provides a theoretical framework for assessing high school accessibility and its impact on enrollment rates, offering valuable insights for policy makers looking to optimize educational resources and promote fairness. The findings highlight the need for further research with larger samples and the inclusion of additional variables to understand the broader impact of accessibility on education.

    This study examines the influence of Systematic Strategic Planning (SSP) on the Sustainable Performance (SP) of manufacturing Small and Medium Enterprises (SMEs) in Pakistan. Despite SMEs' vital contribution to economic growth, there is limited empirical research on how strategic planning enhances sustainable performance in SMEs operating in emerging economies facing political and economic instability. Drawing on the Triple Bottom Line (TBL) and Resource-Based View (RBV) theories, this study investigates the mediating roles of Strategic Intent (SI) and Strategic Formulation (SF) in the SSP-SP relationship. A quantitative research design was employed, and data were collected through structured questionnaires distributed to senior executives and decision-makers of manufacturing SMEs. A total of 410 valid responses were received. Structural Equation Modeling (SEM) was applied using AMOS 28 software to analyze the data and test the hypothesized relationships. The results demonstrate that SSP has a significant direct effect on SP and an indirect effect through SI and SF. Specifically, the components of SSP-strategic analysis, strategy creation, strategy execution, and monitoring and evaluation-enhance SMEs' economic, environmental, and social performance. The study highlights that adopting systematic strategic planning practices enables SMEs to navigate complex and uncertain environments, achieve competitive advantage, and contribute to sustainable development goals. This research fills a critical gap in the literature by focusing on manufacturing SMEs in Pakistan, an under-researched context in the sustainability and strategic management fields. It offers practical insights for SME managers and policymakers to develop and implement comprehensive strategic planning frameworks that foster sustainability. The study also provides theoretical contributions by integrating SI and SF as key mediators within the TBL and RBV theoretical frameworks.

    BACKGROUND: Malaysia provided COVID-19 vaccines for all residents, regardless of citizenship status. However, the extent of vaccine accessibility for migrant populations remains unclear, given the complex healthcare barriers they face. This study explored the barriers migrants faced in accessing COVID-19 vaccines and the measures taken to facilitate their access.

    METHODS: This qualitative study, conducted between April 2022 and February 2023, involved 32 purposively selected key informants from non-governmental organisations (7), international organisations (2), labour unions (2), healthcare providers (11) and migrant communities (10). Data were collected through in-depth, semi-structured, primarily individual interviews, and analysed using NVivo 12 Pro software following a six-phase thematic analysis: data familiarisation, code generation, theme identification, theme review, theme definition, and reporting.

    RESULTS: Thematic analysis identified barriers-including legal and administrative challenges, digital exclusion, vaccine hesitancy, and logistical issues-and facilitators, such as mandatory vaccination policies, innovative delivery approaches, communication support, and community engagement. Substantial challenges arose from pervasive distrust in healthcare services, compounded by identity document requirements, roadblocks, and fears of immigration arrests. Digital appointment systems excluded many migrants due to language and literacy barriers, data privacy concerns, and the need for identity documents. While vaccine hesitancy among migrants was generally low, concerns were primarily driven by fears of immigration enforcement rather than vaccine safety. Despite vaccination being voluntary, mandatory requirements for digital vaccination certificates or negative COVID-19 test results strongly incentivised uptake. Employer support, driven by economic interests, played a critical role in promoting compliance with workplace vaccination mandates. Collaboration with non-governmental organisations and community partners proved pivotal, offering tailored health communication and building trust. Flexible vaccine delivery strategies, including a shift from centralised to outreach models near residences and workplaces, enhanced access, particularly for hard-to-reach populations.

    CONCLUSION: Despite numerous challenges, Malaysia's vaccination efforts were largely successful due to innovative and collaborative delivery and communication strategies. To further improve health equity among marginalised populations, it is essential to enhance culturally sensitive training for frontline workers, strengthen employers' business ethics, and increase the involvement of trusted stakeholders.

    This research investigates the role of dimples in enhancing the aerodynamic characteristics of a Blended-Wing-Body (BWB) airframe. Numerical simulations, grounded in Computational Fluid Dynamics (CFD), were utilized to model turbulent airflow and assess the aerodynamic forces acting on the wing structure. The k-ω Shear-Stress Transport (SST) turbulence model was applied to effectively solve the governing equations. The impact of four dimple indentation depths (d/Dd = 0.025, 0.05, 0.075, and 0.1) at six specific locations on either the suction or pressure sides of the BWB wing surface was investigated. Simulations were performed at Mach 0.15 and Mach 0.6, treating the flow as incompressible and compressible, respectively, to capture variations in aerodynamic behavior. The evaluation involved analyzing the drag coefficient (CD), lift coefficient (CL), and lift-to-drag (L/D) ratio. The results reveal that, under optimal conditions, a dimpled BWB surface can achieve a reduction in CD by as much as 4.09% relative to a non-modified surface, without negatively impacting lift. This improvement is primarily due to the dimples' capacity to maintain attached flow and postpone flow separation. Implementing dimples on the BWB wing surface as a passive flow control method has proven effective in enhancing the aerodynamic efficiency of lifting surfaces.

    Clinacanthus nutans (Sabah snake grass) is widely recognized for its pharmacological properties, particularly its high phenolic content and antioxidant activity. However, the optimization of its ultrasonic-assisted extraction (UAE) remains underexplored. This study aims to enhance the extraction efficiency of phenolic compounds from Clinacanthus nutans leaves using ionic liquid (IL) binary solvents, with optimization based on Peleg's model and Response Surface Methodology (RSM). Peleg's model was used to determine the optimal extraction time, while RSM with a Central Composite Rotatable Design (CCRD) was applied to evaluate the effects of ultrasonic frequency (40-60 kHz) and the ratio of ILs to water (2:8, 5:5 and 8:2) on total phenolic content (TPC), DPPH radical scavenging activity, and Ferric Reducing Antioxidant Power (FRAP). The experimental results were statistically analyzed using ANOVA, model fitting, and desirability functions. Peleg's model indicated that the predicted maximum total phenolic content (TPC) of 42.556 ± 0.0003 mg GAE/g was achieved at an ultrasonic frequency of 50 kHz within 3 hours, making this duration as the predictive model benchmark for further optimization. The optimal extraction conditions were identified as an ultrasonic frequency of 60 kHz and an IL-to-water ratio of 2:8, yielding a maximum TPC of 0.01 ± 7.97 x 10-5 mg GAE/g, DPPH antioxidant activity of 95.08 ± 0.57%, and FRAP antioxidant capacity of 6.31 ± 0.10 mg AEAC/g. Peleg's model inadequately predicted the best exhaustive extraction time prior to RSM leading to a low TPC value throughout the optimization process while maintaining high in antioxidant efficacy. However, the use of IL binary solvents significantly enhanced the release of phenolic compounds compared to conventional solvents, demonstrating their potential as a green extraction alternative. This study highlights the effectiveness of ultrasonic-assisted extraction combined with IL binary solvents for maximizing the recovery of bioactive compounds from Clinacanthus nutans leaves. The optimized extraction method can be beneficial for pharmaceutical, nutraceutical, and functional food industries. Future research should focus on identifying specific phenolic compounds using High-Performance Liquid Chromatography (HPLC), combined kinetic and diffusion equilibrium model and further refining process optimization parameters (e.g., longer concoction duration) to enhance yield efficiency.
