Citation analysis identifies influential scholars, institutions, and sources, further enriching our understanding and knowledge of this domain. Moreover, keyword co-occurrence analysis uncovers key topics and research themes, including e-learning, assistive technologies, and learning systems and guidelines. Additionally, the study identifies research fronts indicating a shift toward Industry 4.0-related topics focused on promoting user-centered design, inclusion, equity, and accessible education through the use of cognitive technologies, artificial intelligence, augmented reality, and virtual learning. This study concludes by discussing notable gaps in the knowledge base and future research opportunities in such areas as curriculum designs, pedagogical approaches, Industry 5.0, and systematic integration of accessibility, ultimately aimed at enhancing inclusive education, enriching the learning experience, and improving learning outcomes for all students regardless of their abilities and backgrounds within engineering education.Item Metadata only Higher education and COVID-19: An adaptive approach in Thailand(2024-06-04) Muangasame K.; Wongkit M.; Muangasame K.; Mahidol UniversityThe aim of this research was to explain the state of higher education in Thailand during the COVID-19 pandemic and evaluate the adaptive approach adopted within the Thai context. Utilising secondary data from Mahidol University International College and Prince of Songkla University, Trang Campus, and employing content analysis techniques, this research attempted to identify the strategies employed by Thai educational institutions to teach their students, evaluated the effectiveness of these methods in the classroom and explored the notable shifts in the education landscape within the country. Eight key components that led to the adaptive approach were found in this study. In addition, three issues related to the post COVID-19 crisis were elaborated as these had an impact on both instructors and students, namely (1) transition to hybrid learning as the preferred mode of course delivery in the post COVID-19 era, (2) students' educational behaviour after the COVID-19 crisis and (3) the impact of online learning on students' sense of belonging to the university community. The research concludes that the leadership team holds a pivotal role in providing guidance and making well-informed decisions. These decisions should encompass six critical aspects: maintaining situational awareness, ensuring effective communication, fostering collaborative improvisation, making timely decisions and taking appropriate actions, engaging in iterative solution experimentation and utilising technology for consistent messaging. All these aspects are essential for steering the university's path. Establishing a foundation for adaptability enables all stakeholders to implement and evaluate their performance.Item Metadata only Inclusive Ethnic Groups for ASEAN Sustainable Development(2024-01-01) Srichampa S.; Srichampa S.; Mahidol UniversityDiversity among ethnic groups is one element of ASEAN’s identity. Members of ethnic groups are entitled to the same rights as everyone else in each member country. Even though ASEAN is committed to the SDGs, member countries are not on track to achieve many of the 17 SDGs by the year 2030. Ethnic groups are acting as agents, recipients, and beneficiaries of ASEAN government policies, so each member-country should ensure ethnic group participation in policy-making in order that “no one is left behind”. This article presents some of the challenges and opportunities related to the ethnic groups of ASEAN, namely: 1) “Know us, know them”; 2) mother-tongue based instruction to prevent “linguistic genocide”; 3) encouraging ethnic group communities to document their Indigenous knowledge; 4) promoting and learning from the ethnic groups’ local wisdom for sustainable environmental preservation; 5) addressing the challenges and opportunities for the ethnic groups in achieving sustainable development; and 6) recognizing the contributions of ethnic group women as eco-protectors. With vigorous and serious cooperation among stakeholders, positive changes and sustainable development is possible. Moreover, ethnic group diversity and their distinct identities in ASEAN will be maintained, promoted, and strengthened by the affirmative policies of member-country governments. Cultural identity and diversity are applied in this analysis.Item Metadata only Advancing Point-of-Care Diagnosis: A Development of Magnetofluidic Platform(2024-01-01) Srisamrid T.; Avirothanapong J.; Jitnarin P.; Nasongkla N.; Horthongkham N.; Arnin J.; Athamanolap P.; Srisamrid T.; Mahidol UniversityThe development of the point-of-care (POC) diagnostic platform presents a significant advancement in modern healthcare, offering enhanced accessibility, speed, and accuracy in detecting various pathogens.

During the physical examination, the animal had an intra-abdominal mass with abdominal discomfort. No history of vomiting and diarrhea was reported. The blood chemistry and hematology revealed a markedly low albumin/globulin ratio and mild anemia with normal leukogram. The abdominal ultrasonographic examination and CT scan revealed an intestinal mass at the ileocecocolic junction. The mass was surgically excised, and jejuno-colic anastomosis was performed. Grossly, the mass was firm, very well circumscribed, measured 6×7×5 cm in diameter, and had fairly discrete central areas of tan to white discoloration. Microscopically, the wall of the large intestine was regionally extensively expanded by abundant, dense, thick bands of fibroplasia with associated dense infiltrates of predominant eosinophils, fewer lymphocytes and plasma cells, and multifocal areas of necrosis. Special staining for toluidine blue, Masson’s trichrome, Periodic Acid Schiff (PAS), and Grocott Gomori methenamine silver stain (GMS) along with immunohistochemistry for CD3, CD20, and KIT was performed to rule out the possibility of infectious disease and other potential neoplasms such as mast cell tumor, lymphoma, and gastrointestinal stromal tumor. Taken together, the observed findings were most consistent with feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF). The immunosuppressive drugs were administered: prednisolone 2 mg/kg, orally every 24 hours, and cyclosporine 4.8 mg/kg, orally every 24 hours. The prednisolone dosage was tapered down by 25% every six weeks. There was no evidence of local recurrence detected in 172 days post-operation. In this case, a successful combination of surgical and medical treatment protocols and diagnostic techniques of the FGESF case was presented.Item Metadata only Hybrid Image-Based Motion Tracking and Adaptive Polynomial Kalman Filter for a Bio-Inspired Dual-Sheath Needle System(2024-01-01) Sivaraman D.; Wiratkapun C.; Pillai B.M.; Suthakorn J.; Methachan B.; Nakdhamabhorn S.; Ongwattanakul S.; Sivaraman D.; Mahidol UniversityThis preliminary study investigated sensor-fusion methods for accurate motion estimation in a bio-inspired dual-sheath needle system designed for biopsy applications. The needle system draws inspiration from the segmented dual-sheath mechanism of ovipositors found in Hymenoptera species, which allows controlled and precise movement. The aim is to develop a reliable tracking system for both the needle tip and base, which is essential for accurate needle placement during biopsy procedures. A hybrid tracking approach was used to achieve this, combining image-based tracking of the needle tip with an Inertial Measurement Unit (IMU) sensor for needle-base tracking. An Adaptive Polynomial Kalman Filter (APKF) was applied to improve the motion estimation accuracy. Performance tests on a linear-rail system demonstrated the ability of the developed system to provide accurate and consistent motion estimates. The results suggest that this bio-inspired needle system using sensor fusion and advanced filtering holds promise for use in medical robotics, potentially improving the precision of biopsy procedures.Item Metadata only Real-world usage pattern, effectiveness and safety of oral tramadol/dexketoprofen trometamol fixed-dose combination in moderate-to-severe acute pain in Asia: A prospective, multicentre, observational study(2024-10-17) Ho K.Y.; Gyanwali B.; Dimayuga C.; Eufemio E.M.; Bernardo E.; Raju G.; Chong K.W.; Waithayayothin K.; Ona L.; Castro M.A.L.; Sawaddiruk P.; Salvador R.C.; Roohi S.A.; Tangwiwat S.; Wilairatana V.; Oon Z.H.; Gupta A.; Nagrale D.; Ho K.Y.; Mahidol UniversityObjectives This study aims to determine the usage pattern, effectiveness and safety of oral tramadol 75 mg and dexketoprofen trometamol 25 mg fixed-dose combination (TRAM/DKP FDC) in the short-term treatment of moderate-to-severe acute pain in real-world clinical practice in Asia. Design Real-world, prospective, multicentre, observational, phase IV study. Setting 13 tertiary-care hospital sites across the Philippines, Thailand, Malaysia and Singapore. Participants Adult patients aged 18-80 years prescribed TRAM/DKP FDC for the short-term (up to 5 days) treatment of moderate-to-severe acute pain. Main outcome measures Primary endpoints were the proportion of patients prescribed TRAM/DKP FDC with different types of postsurgical and non-surgical treatments, and the average dosing frequency and duration of TRAM/DKP FDC treatment. Secondary endpoints were the proportion of patients achieving ≥30% pain reduction at 8 hours post the first dose (pain severity was assessed using the 11-point Numeric Pain Rating Scale); patient satisfaction at the end of treatment (based on a 5-point Patient Global Evaluation Scale (PGE)) and safety including the incidence of adverse drug reactions (ADRs). Results Among 599 patients (median age 44 years, 61.3% female) enrolled in this study, 68.61% (n=411) were postsurgical and 31.39% (n=188) were non-surgical patients. TRAM/DKP FDC was prescribed in a diverse group of postsurgical patients (eg, orthopaedic, general and cancer surgery) as well as in non-surgical conditions (eg, lower back pain and musculoskeletal pain). In the majority of patients, TRAM/DKP FDC was prescribed every 8 hours (65.94%) and for 5 days (78.80%). There was a significant reduction in pain intensity throughout the study and 65% of patients achieved ≥30% pain reduction from baseline at 8 hours post the first dose of TRAM/DKP FDC on day 1. 95.69% of patients were satisfied with the treatment (rated good, very good and excellent on the PGE scale). Overall, 13.9% of patients reported ADRs; most were mild to moderate in severity. The most common ADRs were nausea, vomiting and dizziness. Conclusion This study showed that TRAM/DKP FDC was used in diverse types of postsurgical and non-surgical patients in the real-world setting in Asia. It effectively reduced pain and was well tolerated with a high level of patient satisfaction.Item Metadata only Genetic Diversity and Population Dynamics of Clinostomum spp. Using Comprehensive Bioinformatics Approaches(2024-01-01) Islam S.I.; Hamad M.H.; Jitsamai W.; Rodkhum C.; Taweethavonsawat P.; Islam S.I.; Mahidol UniversityClinostomum species, a parasitic pathogen of freshwater fish, is widely distributed and infects various host species. Recently, the pathological effect due to Clinostomum metacercarial infection was described in aquaculture in Thailand; however, the global genetic diversity and population structure of this species have not been studied yet. Therefore, this study aimed to provide a detailed description of genetic diversity and population dynamics of the digenean Clinostomum isolated from Trichopodus pectoralis with globally recorded Clinostomum species. The species was characterized molecularly by analyzing 18S rDNA and inter-transcribed spacer biomarker genes (ITS1 and ITS2). A BLAST search discovered that the 18S rDNA and ITS sequence had a 100% sequence similarity with Clinostomum piscidium isolated from India and Thailand. A comprehensive analysis revealed the presence of 12 distinct haplotypes among the Clinostomum populations. This study suggests that distinct patterns of genetic variation were identified by analyzing molecular variance, pairwise Fst, and employing structure analysis. It was observed that a gradient of genetic variation exists within continents, characterized by higher levels within different groups and lower levels of genetic differentiation. Additionally, a notable presence of mixed haplotypes was observed. The results of neutrality testing suggest that there has been a significant expansion in the populations of Clinostomum in India, America, and Kenya. The discoveries from this study will provide a valuable contribution to comprehending the genetics and evolution of Clinostomum species. Furthermore, key findings will be essential in developing efficient management approaches to prevent and control this parasite.Item Metadata only Successful Transcatheter Edge-to-Edge Mitral Valve Repair via Minithoracotomy in Canine Myxomatous Mitral Valve Disease: Case Report(2024-07-01) Kijtawornrat A.; Brikshavana P.; Kulabsri S.; Wijitratanagorn V.; Booncharoensombat N.; Chinnabrut P.; Bunjerdsuwan W.; Rujivipat N.; Saengklub N.; Kijtawornrat A.; Mahidol UniversityTranscatheter edge-to-edge mitral valve repair (TEER) for the correction of mitral regurgitation (MR) due to myxomatous mitral valve disease (MMVD) stage B1 in a dog by a hybrid intervention technique via mini-thoracotomy was first reported in Thailand and Southeast Asia. The dog did not show any clinical signs related to congestive heart failure (CHF). Physical examination revealed systolic murmur grade III/VI. Electrocardiographs were recorded and showed normal sinus rhythm. A thoracic radiograph revealed the normal size and shape of the heart (VHS 10.9) and diffuse bronchial pattern in the lungs. A definitive diagnosis of MMVD was made by echocardiography. The dog received MR correction by transcatheter edge-to-edge mitral valve repair (TEER) guided by transesophageal echocardiography (TEE). The procedure was successful, as indicated by the absence of regurgitant jet flow from the left ventricle into the left atrium and the lack of complications. Ten days after the operation, echocardiography, complete blood count, and blood chemistry profiles were obtained, and the dog remained healthy.Item Metadata only Intra-Operative Trajectory Realignment Algorithm for Minimizing Pedicle Screw Misplacement in Cervical Spinal Fusion(2024-01-01) Komonsuwan P.; Treratanakulchai S.; Chumnanvej S.; Suthakorn J.; Komonsuwan P.; Mahidol UniversityCervical spinal fusion is a surgical procedure that requires precise pedicle screw placement to ensure successful outcomes and avoid complications. Traditional manual methods rely on the surgeon's experience and anatomical landmark identification, which can lead to misalignment errors and complications. This study proposes an intra-operative trajectory re-alignment algorithm designed to address discrepancies between pre-operative and intra-operative images, particularly due to the inherent mobility of the cervical spine. The algorithm utilizes 3D CT scans for pre-operative imaging and 2D X-rays for intra-operative imaging. Principal Component Analysis (PCA) is applied to each 3D segmented spine to construct reference frames. These kinematic frames are manipulated to optimize the error between the simulated X-ray images and the reference 3D CT images. The CTspine1K data was used to evaluate the proposed algorithm by measuring geometric and clinical errors. The results show that the proposed algorithm reduces errors, and preventing screw perforation.Item Metadata only A Hybrid EEG-EMG Framework for Humanoid Control using Deep Learning Transformers(2024-01-01) Olikkal P.; Pillai B.M.; Suthakorn J.; Ali H.; Vinjamuri R.; Olikkal P.; Mahidol UniversityBrain-computer interfaces (BCIs) offer promising solutions for upper limb rehabilitation. Despite advancements in deep learning, traditional models for motor rehabilitation using electroencephalography (EEG) or electromyography (EMG) to control assistive devices require enhancement. This study aims to enhance motor control capabilities by integrating EEG and EMG signals using a Transformer-based deep learning model. Ten able-bodies subjects performed center-out tasks on a low-cost upper limb rehabilitation table, capturing 2D kinematic data, EEG, and EMG signals simultaneously. The tasks varied in complexity across four levels. Preprocessed EEG and EMG signals were fused and given as input to the proposed model, which was evaluated using three performance metrics. Results showed that the EEG-EMG combined model achieved 87.27% accuracy across all the four levels. Furthermore, the model's output successfully controlled a humanoid robot to replicate similar movements. These findings highlight the efficacy of combined EEG-EMG data in improving accuracy and performance in BCI applications, advancing assistive technologies and neurorehabilitation interventions.Item Metadata only Artificial Esophagus for Measuring Ballooning Contacting Pressure(2024-01-01) Detasavanong P.; Kao-Ian Y.; Srisutrapon K.; Welch P.E.; Paibunviriyakun N.; Kitiyakara T.; Treratanakulchai S.; Detasavanong P.; Mahidol UniversityGastroesophageal reflux disease (G ERD) is a con-dition where gastric juice in the stomach persistently flows back up into the esophageal tract. GERD symptoms range from mild heartburn and stomach acid leakage to severe esophageal complications. A conventional method to prevent acid reflux involves using a balloon to block the acid. However, prolonged use of a balloon can cause necrosis at the contact site. To prevent this, the contacting pressure requires optimal pressure adjustment. In this work, an artificial esophagus is proposed to measure contacting pressure by examining the deformation of a soft-tubular structure. The displacement of surface fiducials is tracked using imaging under given internal pressure, which represents the normal pressure exerted on the esophagus. The contacting pressure during inflation was compared between an extensible balloon (rubber-like) and a strain-limiting balloon (LDPE tube) inside the proposed soft esophagus. The results show that the strain-limiting balloon requires lower input pressure to generate a contacting pressure, and this pressure is limited by its strain. In contrast, the rubber-like balloon generates a contacting pressure non-linearly without constraint. Since rubber-like materials have hyper-elastic characteristics, their expansion could grow exponentially at high pressure, posing a high risk of esophageal tissue necrosis to patients.Item Metadata only Enhancing Post-Stroke Upper Limb Rehabilitation Through Haptic Feedback in Virtual Reality-Based Gaming(2024-01-01) Pillai B.M.; Siripala N.; Sai-Aroon K.; Sivaraman D.; Vinjamuri R.; Chumnanvej S.; Suthakorn J.; Pillai B.M.; Mahidol UniversityThis preliminary study explores developing and implementing upper-limb rehabilitation tools utilizing haptic feedback and 3D spatial recognition analysis in a virtual reality (VR) environment. The effectiveness of upper limb rehabilitation in post-stroke patients was investigated by analyzing the joint and gimbal range of motion (ROM), ROM ratios, and force distribution through various drawing tasks. This study evaluated the impact of different drawing patterns on joint and gimbal ROM, and the force applied during rehabilitation exercises. This study revealed significant variability in ROM across different tasks by combining ROM measurements with force data and employing heat maps for visual representation. These findings emphasize the need for task-specific adjustments to improve rehabilitation outcomes. This study highlights the potential of incorporating advanced technologies, such as VR-based tools with haptic feedback and 3D spatial recognition, to enhance patient engagement and rehabilitation effectiveness.Item Metadata only Albumin Detection Kit for Early Kidney Disease Indication Using Imprinted Graphene Oxide/Polyhydroxyalkanoate Membrane(2024-01-01) Thanombooncharoen S.; Smirnova M.; Wijitpanya N.; Boonyagul S.; Kaewjai C.; Laungsopapun G.; Sathirapongsasuti N.; Panaksri A.; Tanadchangsaeng N.; Thanombooncharoen S.; Mahidol UniversityKidney disease is a significant health issue in Thailand, affecting about 17.5% of the population, making early detection crucial to prevent the disease from advancing to more severe and costly stages. Traditional diagnostic methods, including urine and blood tests, are effective but often invasive, time-consuming, and require professional supervision, limiting their accessibility for regular screening. This study introduces a novel, cost-effective kidney disease screening kit designed for convenient at-home use. The kit utilizes a graphene oxide (GO) and polyhydroxyalkanoate (PHA) composite membrane, combined with the albumin protein imprinting technique, to selectively capture human albumin (ABH) through the syringe-push membrane absorption (SPMA) technique. The captured albumin interacts with a coomassie brilliant blue G-250, resulting in a color change that correlates with albumin concentration. The study's findings indicate that the addition of graphene oxide improves the membrane's morphology, enhancing its ability to capture albumin. A linear relationship between the blue color intensity and albumin concentration was established, ranging from 0% at 0 mg/mL to approximately 18% at 1 mg/mL, which enabled the creation of a semi- quantitative color strip model for easy reference. The kit demonstrated effective albumin detection across this concentration range, providing both qualitative and semi- quantitative data. These results suggest that this screening kit could serve as a practical and accessible tool for early kidney disease detection, offering a promising alternative to traditional diagnostic methods by enhancing ease of use and affordability.Item Metadata only Biopreservation of dairy products using postbiotics(2024-01-01) Awasti N.; Vashisht P.; Khanashyam A.C.; Shah K.; Nirmal N.P.; Awasti N.; Mahidol UniversityThe dairy industry faces significant challenges in preserving the quality and safety of its products while meeting consumer demand for minimally processed and naturally preserved foods. Postbiotic biopreservation has emerged as a promising technique to address these challenges. Postbiotics are the metabolites and by-products generated by beneficial microorganisms during fermentation, particularly lactic acid bacteria (LAB). Postbiotics play a pivotal role in acidifying the environment, inhibiting the growth of spoilage microorganisms and pathogens, and enhancing the sensory attributes of products. This chapter provides an overview of the applications of postbiotic as a biopreservative in dairy, highlighting its benefits in extending shelf life, improving food safety, enhancing quality, and offering potential health benefits. Furthermore, it emphasizes the importance of ongoing research and development in optimizing postbiotic production, regulatory compliance, and consumer acceptance to fully unlock the potential of this natural preservative in the dairy industry.Item Metadata only Postbiotics: A health promoters in human(2024-01-01) Khanashyam A.C.; Ramesh B.; Babu K.S.; Mundanat A.S.; Shah K.; Awasti N.; Deokar G.S.; Nirmal N.P.; Khanashyam A.C.; Mahidol UniversityPostbiotics represent a novel category within the realm of biotics, demonstrating the potential to impart health benefits. Diverging from probiotics, postbiotics operate independently of living cells, thereby circumventing the food safety requisites applicable to live microorganisms. Constituents of postbiotics encompass an array of elements, such as short-chain fatty acids, exopolysaccharides, vitamins, bacteriocins, enzymes, and peptides, embedded within a nonpurified inactivated cell preparation. Although the exploration of postbiotics is in its nascent stages, mounting evidence suggests their capacity to modulate human health. Recent investigations have unveiled additional bioactivities associated with postbiotics, spanning immunomodulatory, antiproliferative, and antioxidant attributes. Notably, certain postbiotics have exhibited the capability to enhance gut health by fortifying the integrity of the gut barrier, mitigating inflammation, and fostering antimicrobial activity against gut pathogens. Despite the accumulation of in vitro and in vivo studies bolstering the prospective role of postbiotics as promoters of health, the intricacies of their mechanisms of action and the underlying signaling pathways remain incompletely elucidated. This chapter furnishes a comprehensive survey of emerging probiotic-related concepts, outlines the scientific evidence substantiating their bioactivities, delves into potential mechanisms that underlie their health-promoting effects, and examines prevailing trends in their applications.Item Metadata only Practical Mobile Based Services for Identification of Chicken Diseases from Fecal Images(2024-01-01) Silapachote P.; Srisuphab A.; Damkham W.; Korkiattrakool P.; Songdechakaivut K.; Silapachote P.; Mahidol UniversityPoultry farming is a vital component in a food chain. Health of chickens in the farms directly plays an important role in both quality and safety of all chicken products. Accurate diagnosis of poultry diseases from chicken feces using standardized polymerase chain reaction is relatively very expensive, making it rather challenging especially for small local farms. To tackle this, we developed a practical mobile-based service that aimed to provide local farmers an easy-to-use tool capable of preliminary identification of common diseases chickens may have from their fecal images. Our system was deployed as an official Line account on a familiar Line application that most farmers have on their mobile phones. Trained and evaluated on a large open database of chicken fecal images, it achieved a segmentation mean average precision of 86.49 % and classification accuracy of 95.93 %. Ours also, with high confidence, correctly identify healthy images taken by local farmers.Item Metadata only Deep Learning for Automatic Classification of Carotenoid Associated Color Pigmentation(2024-01-01) Ruaydee K.; Kusakunniran W.; Srichamnong W.; Ruaydee K.; Mahidol UniversityThis study explores the application of deep learning models, specifically ResNet-34, ResN et-50, and EfficientNet-B0, for the automatic classification of carotenoid-associated color pigmentation in tomatoes. The dataset comprises 250 images categorized into five pigmentation levels, reflecting the varying carotenoid content. Carotenoids, such as lycopene and beta-carotene, are key pigments influencing the color of tomatoes, with deeper reds and oranges indicating higher concentrations. The models were evaluated for direct classification and regression followed by classification. Results show that EfficientNet-B0 achieved the highest accuracy in direct classification (94.00%), while ResNet-34 excelled in regression tasks (91.33%). Future research will continue exploring regression tasks to predict actual carotenoid content in tomatoes, enhancing prediction accuracy and robustness.
