Item Effect of the Variation of Solid/Liquid Content in Food on the Sterilizing Time and Physical Properties of Chicken and Turkey Berries in Green Curry in Retort Pouch(Taylor and Francis Ltd., 2025) Teeranuch Chysirichote; Weawwan Wattanasiriwit; Kamontip Ploykrachang; Teerin Chysirichote; T. Chysirichote; Department of Food Engineering, School of Engineering, King Mongkut’s Institute of Technology Ladkrabang, Bangkok, 1 Chalongkrung 1 Rd, Ladkrabang, Thailand; email: teerin.ch@kmitl.ac.thWhen industrial sterilizing is being done on a large scale, retort pouches are typically loaded with solid components first, followed by liquid ones. The error of filling steps occurs before the sterilization procedure is feasible. The curry with chicken and turkey berries was chosen as the food protocol to be studied. The food’s solid/liquid ratio was tested, from 0.93 to 4.49. The process time was influenced by the heat capacity ratio of the solid and liquid, but it was not considerably affected by the solid/liquid ratio. As a result, the process time had an impact on the texture and color of the meat but had no effect on the texture of the vegetables for process periods between 5 and 12 min (F0 = 4). The process time was earlier researched; however, the results of this study were used to roughly estimate the process time in the instance of the F0. © 2023 Taylor & Francis Group, LLC.Item Avatar influence: How form realism and message appeal shape Generation Z's travel intentions(Elsevier Ltd, 2025) Zhen Su; Biman Lei; Shichang Liang; Tanaporn Khotphat; Qi Hu; S. Liang; Business School, Guangxi University, Nanning, No. 100 East Daxue Road, 530004, China; email: liangshch@gxu.edu.cnAlthough avatars have gained popularity in virtual reality marketing, research on their influence on Generation Z consumers' travel intentions remains limited. Drawing on the Construal Level Theory and the Elaboration Likelihood Model, this study examined the congruent effects of avatar form realism and message appeal on Generation Z's travel intentions through three experimental scenarios. The findings indicate that high-form realism avatars with rational appeal and low-form realism avatars with emotional appeal significantly boost travel intentions. These effects are mediated by believability and affect intensity and are more pronounced among individuals with low behavioral realism expectations. This study enhances our understanding of avatar-mediated persuasion in tourism marketing by linking core avatar attributes to consumer decision-making processes. These insights enable us to leverage the visual and verbal components of avatars to promote destinations that attract young travelers. © 2025 The AuthorsItem Effects of traditional Thai folk dance combined with cognitive stimulation program on behavior and cognition among older adults with cognitive decline: A randomized controlled trial(2025) Panawat Sanprakhon; Wachira Suriyawong; Natsala Longphasuk; Natsuda Khatichop; Churai Arpaichiraratana; Sresuda Wongwiseskul; Peerayut Rattanaselanon; Noppamas Pipatpiboon; Papan ThaipisuttikulBACKGROUND: Older adults with mild behavioral impairment (MBI) are at the higher risk of developing dementia compared to those without MBI, leading to decreased quality of life (QoL). Addressing MBI in older adults provides valuable opportunities to prevent dementia. OBJECTIVES: This study aimed to determine the effects of traditional Thai folk dance combined with a cognitive stimulation program on MBI, QoL, subjective cognitive decline (SCD), and cognitive functioning in older Thai adults. DESIGN: Single-blinded, two-armed, randomized controlled trial, with a three-month follow-up period. SETTING: Outpatient chronic disease clinics at two districts in Suphan Buri province, Thailand. PARTICIPANTS: One-hundred twenty-eight older adults with MBI were randomly assigned to either the experimental (n = 64) and cognitive education control group (n = 64). INTERVENTION: The 14-session, 7-week traditional Thai folk-dance program combined with cognitive stimulation focused on enhanced moderate intensity physical activity and cognitive stimulation engagement to improve MBI of older adults. MEASUREMENTS: The primary outcome was MBI assessed using Mild Behavioral Impairment Checklist. Secondary outcomes were QoL, SCD, and cognitive tests of memory and executive functions. RESULTS: Compared to the control group, participants in the experimental group demonstrated significantly reduced MBI (p <.01), improved QoL (p <.01), decreased SCD (p <.01), and enhanced cognitive functioning (p <.01) after the 7-week intervention and at the 12-week follow-up. CONCLUSION: The traditional Thai folk dance combined with cognitive stimulation improved outcomes related to early signs of dementia and enhanced the overall QoL of older adults.

Pichaiyongvongdee; Department of Innovation Technology for Food Entrepreneur, School of Culinary, Suan Dusit University, Bangkok, Thailand; email: suwanna_pic@dusit.ac.thIn general, most traditional cream soups are high in carbohydrates and low in calcium, fiber, and phytochemicals, which reduces their nutritional value. Therefore, the development of purple sweet potato soup fortified with Chinese kale was important to enhance its nutritional value and address malnutrition. This innovative product combines the health benefits of purple sweet potato due to its antioxidant properties, while Chinese kale was a rich source of calcium and dietary fiber, making it a more nutritious and health-promoting food. This research investigated the effects of different pre-processing and drying methods on the physicochemical and cooking properties of freeze-dried soup products made from purple sweet potato (PP) and Chinese kale (CK). CK was blanched in 1% NaCl and 1% NaHCO3 solutions and then tray-drying and freeze-drying techniques were used. It was found that CK branched in 1% NaCl solution and freeze-dried retained significant levels of chlorophyll, calcium, fiber, and antioxidants. © 2025 The Author(s).

Buapool; Department of Sustainable Industrial Management Engineering, Faculty of Engineering, Rajamangala University of Technology Phra Nakhon, Bangkok, 10800, Thailand; email: sorasutee.b@rmutp.ac.thThe construction industry has increasingly emphasized the importance of sustainable materials. These sustainable materials offer insights into the development of effective and ecofriendly acoustic materials. This study explored the potential of water hyacinths for sound absorption performance. An impedance tube test was conducted to analyze the sound absorption coefficient. The specimens were fabricated by spraying dried water hyacinth stalks with a polyvinyl alcohol adhesive, allowing them to dry and then cutting them into different thicknesses for measurement. A systematic analysis revealed that the sound absorption coefficients improved with increasing thickness and air-gap depth. The specimen reached its highest sound absorption coefficient value of 0.73 at 500 Hz with a thickness of 10 mm and an air gap depth of 20 mm. A greater thickness significantly enhanced the sound absorption, and additional air-gap depths further improved it. These factors correlated with higher noise reduction coefficient values (0.24 to 0.41), highlighting water hyacinth's suitability as a sound-absorbing material. Water hyacinth offers excellent sound absorption and aesthetic value. © 2025 The Korean Society of Wood Science & Technology.Item A modified inertial projected forward–backward algorithm for convex optimization problems(Springer-Verlag Italia s.r.l., 2025) Kunrada Kankam; Papatsara Inkrong; Prasit Cholamjiak; P.

Sarwar; Department of Mathematics, University of Malakand, Khyber Pakhtunkhwa, Pakistan; email: sarwar@uom.edu.pkIn this study, we investigate the Bielecki-Ulam (B-U) stabilities of two forms of Hammerstein-type difference systems (HT-DS). Specifically, we consider the systems: (0.1){xm+1−xm=M¯mxm+F¯(m,xm,xhm)[∑[j=0][m]G¯(m,j)H¯(j,xj,xhj)]x0=b0,and (0.2){xm+1−xm=M¯mxm+F¯(m,xm,L¯xm,J¯xm)x0=b0,by establishing conditions under which a unique solution exists. We derive sufficient conditions for the existence and uniqueness of solutions that satisfy B-U stability criteria. To demonstrate the theoretical findings, we provide an illustrative example that confirms the validity of our results. • Purpose: In this study, we examine the Bielecki-Ulam (B-U) stabilities of two forms of Hammerstein-type difference systems (HT-DS) to understand the conditions necessary for solution uniqueness and stability. • Methodology: We analyze two specific systems characterized by distinct recursive nonlinear structures and employ the Banach contraction principle under the Bielecki norm to establish stability results. The theoretical development involves verifying boundedness and Lipschitz continuity of the nonlinear terms and ensuring that the involved operators satisfy contractive conditions. • Findings: We derive sufficient conditions (outlined in Theorems 2 and 3) under which the systems possess unique solutions and are shown to be Bielecki-Ulam stable (Theorems 4 and 5). Specifically, these conditions include boundedness of system coefficients, Lipschitz continuity of nonlinear mappings, and the fulfillment of a contraction inequality using the Bielecki norm. Illustrative examples are provided to confirm the applicability of the results. © 2025 The Author(s)Item A double inertial embedded modified S-iteration algorithm for nonexpansive mappings: A classification approach for lung cancer detection(Elsevier B.V., 2025) Watcharaporn Yajai; Kunrada Kankam; Jen-Chih Yao; Watcharaporn Cholamjiak; W. Cholamjiak; Department of Mathematics, School of Science, University of Phayao, Phayao, 56000, Thailand; email: watcharaporn.ch@up.ac.thThis paper introduces a double inertial embedded modified S-iteration algorithm for finding a common fixed point of nonexpansive mappings in a real Hilbert space. A weak convergence theorem is established under suitable conditions involving control parameters. Three algorithms are directly obtained for addressing split equilibrium problems through the equivalence of nonexpansive mappings. An illustrative example in an infinite-dimensional space is provided to substantiate the proposed main algorithm. Furthermore, we highlight the practical application of these algorithms in lung cancer screening, where they are employed to optimize three different machine learning models, thereby potentially improving patient outcomes. The efficiency of the proposed algorithms is validated through comparative analysis with existing algorithms. © 2025Item Aroma profiles and potential odour-active compounds in Thai fish sauce produced from anchovies caught from three different coastal regions in Thailand(Taylor and Francis Ltd., 2025) Wasana Wongngam; Thanaporn Pengjun; Apiniharn Phewpan; Chanchana Siripanwattana; Nattapon Deesom; Suwimon Keeratipibul; Thiranan Kunanopparat; T. Kunanopparat; Pilot Plant Development and Training Institute, King Mongkut’s University of Technology Thonburi, Bangkok, 126 Pracha Uthit Rd. Bangmod, Thung Khru, 10140, Thailand; email: thiranan.kun@kmutt.ac.thThai fish sauces produced from anchovies caught from three different coastal regions of Thailand [the western (WT), eastern (ET), and southern (ST)] had similar overall sensory aroma profiles with strong fishy and meaty odours followed by sweet, cheesy, sour and musty odours. The 3 fish sauces differed in the intensity levels of these 6 attributes. Fish sauce odourants were extracted by solvent extraction followed by solvent-assisted flavor evaporation (SAFE) and analyzed by gas chromatography-olfactometry (GC-O). Odour-active compounds of three fish sauces were analyzed using aroma extract dilution analysis (AEDA) with flavor dilution (FD) factor ≥1024. There were 18 potential odour-active compounds which exhibited FD factor ≥128 in at least one of the studied fish sauces. Differences in the FD factors of these odourants between each fish sauce were found. These results suggested that anchovies caught from different regions contributed to the different sensory profiles of the fish sauces. © 2025 The Author(s).

Ganeshaborirak; Program in Agriculture, Faculty of Agricultural Production, Mae Jo University, Thailand; email: raveeganesha@gmail.comThe International Federation of Organic Agriculture Movement (IFOAM) indicates that the detrimental impact of pesticide residues in chilli pepper production for consumption prompted the creation of a prototype approach for cultivating organic chilli peppers to safeguard safety and human health. Researchers conducted an inquiry on a chilli pepper crop in Lampang province and examined the simulation of organic chilli growing in an IFOAM-certified region at the Biological Control Technology Learning Centre, Maejo University, Chiang Mai, Thailand. The analysis effectively optimised organic chilli pepper output to comply with regulations by meticulous selection of planting materials, fertilisers, and pest management techniques. The research was carried out in Lampang province and at the IFOAM-certified site at Maejo University, Chiang Mai, Thailand. The inquiry effectively adhered to organic standards through the selection of planting materials, fertilisers, and pest management techniques. The prototype technique involved utilising certified seeds, organic fertilisers, Trichoderma sp. for pest management, and natural predators such as stink bugs. The objective was to attain a plant density of 5,000-6,000 plants per rai. Researchers controlled insect pests by employing stink bugs to manage chilli pepper cutworms 7–14 days post-transplantation, thereafter applying Beauveria bassiana and neem extract solution at 21 and 28 days after transplantation, respectively. The prototype yielded chilly paper at 1,680 ± 4.27 kg/rai, comparable to the regular manufacturing schedule. The study found a favourable correlation between pest control approach and pest epidemic number (R2 = 0.86) as well as plant disease (R2 = 0.53). Simultaneously, the quantity of insect epidemics and plant diseases had a positive link with crop yield, with R2 values of 0.65 and 0.67, respectively. The research established a prototype that presents a sustainable, pesticide-free production technique for chilli peppers, promoting the green economy and furnishing a practical guidance for farmers to implement organic methods. © (2025), (University of Kassel).

Sarwar; Department of Mathematics, University of Malakand, Chakdara, Khyber Pakhtunkhwa, 18800, Pakistan; email: sarwarswati@gmail.com; K. Abodayeh; Department of Mathematics and Sciences, Prince Sultan University, Riyadh, 11586, Saudi Arabia; email: kamal@psu.edu.saIn this manuscript, the notion of a hesitant fuzzy soft fixed point is introduced. Using this notion and the concept of Suzuki-type (μ, ν)-weak contraction for hesitant fuzzy soft set valued-mapping, some fixed point results are established in the framework of metric spaces. Based on the presented work, some examples reflecting decision-making problems related to real life are also solved. The suggested method’s flexibility and efficacy compared to conventional techniques are demonstrated in decision-making situations involving uncertainty, such as choosing the best options in multi-criteria settings. We noted that the presented work combines and generalizes two major concepts, the idea of soft sets and hesitant fuzzy set-valued mapping from the existing literature.

Chumkaew; Faculty of Home Economics Technology, Rajamangala University of Technology Thanyaburi, Pathum Thani, 12110, Thailand; email: krittin_c@rmutt.ac.thThai desserts are renowned for their unique characteristics, with coconut being a crucial ingredient. However, the limited availability and high cost of mature coconut pose challenges for dessert production. This study aimed to investigate green papaya substitution in caramelized grated coconut (Na Kra Cheek) and evaluate its properties and application. Different substitution levels (0%, 25%, 50%, 75%, and 100% w/w) were analyzed for sensory qualities, nutritional properties, and consumer acceptance through expert panels (n=15) and consumer testing (n=50). The results showed that 50% substitution maintained sensory acceptance comparable to the control (p≥0.05) in appearance, taste, texture, and overall acceptance while reducing protein content from 2.15% to 1.23%, fat content from 13.70% to 6.83%, and total carbohydrate content from 64.80% to 58.31%. The application in sticky rice dessert demonstrated no significant differences (p≥0.05) in consumer acceptance between control and 50% substitution formulas in all characteristics including appearance, color, smell, taste, texture, and overall acceptability, with overall acceptability scores of 7.50±0.78 and 7.28±0.85, respectively. Production costs decreased by 36.24% with 50% substitution. These findings suggest that green papaya can effectively substitute for mature coconut up to 50% in Thai desserts, offering cost-effective and healthier alternatives while maintaining traditional qualities. This innovation provides practical solutions for addressing both availability and cost challenges in Thai dessert production while potentially offering more nutritious options to consumers. The similarity in physical properties and the year-round availability of green papaya make this a viable approach for preserving Thai culinary traditions while addressing contemporary economic and nutritional considerations.

Suanpang; Department of Information Technology, Faculty of Science & Technology, Suan Dusit University, Bangkok, Thailand; email: pannee_sua@dusit.ac.thThe growing prevalence of electric vehicles (EVs) in urban settings underscores the need for advanced decision-making frameworks designed to optimise energy efficiency and improve overall vehicle performance. Regenerative braking, a critical technology in EVs, facilitates energy recovery during deceleration, thereby enhancing efficiency and extending driving range. This study presents an innovative Q-learning-based approach to refine regenerative braking control strategies, aiming to maximise energy recovery, ensure passenger comfort through smooth braking, and maintain safe driving distances. The proposed system leverages real-time feedback on driving patterns, road conditions, and vehicle performance, enabling the Q-learning agent to autonomously adapt its braking strategy for optimal outcomes. By employing Q-learning, the system demonstrates the ability to learn and adjust to dynamic driving environments, progressively enhancing decision-making capabilities. Extensive simulations conducted within a smart city framework revealed substantial improvements in energy efficiency and notable reductions in energy consumption compared to conventional braking systems. The optimisation process incorporated a state space comprising vehicle speed, distance to the preceding vehicle, battery charge level, and road conditions, alongside an action space permitting dynamic braking adjustments. The reward function prioritised maximising energy recovery while minimising jerk and ensuring safety. Simulation outcomes indicated that the Q-learning-based system surpassed traditional control methods, achieving a 15.3% increase in total energy recovered (132.8 kWh), enhanced passenger comfort (jerk reduced to 7.6 m/s3), and a 13% reduction in braking distance. These findings underscore the system's adaptability across varied traffic scenarios. Broader implications include integration into smart city infrastructures, where the adaptive algorithm could enhance real-time traffic management, fostering sustainable urban mobility. Furthermore, the improved energy efficiency reduces overall energy consumption, extends EV range, and decreases charging frequency, aligning with global sustainability objectives. The framework also holds potential for future EV applications, such as adaptive cruise control, autonomous driving, and vehicle-to-grid (V2G) systems. © 2025 Regional Association for Security and crisis management.

Gupta; SOS-Engineering and Technology, Guru Ghasidas Vishwavidyalaya, Department of Electrical Engineering, Bilaspur, Chhattisgarh, 495009, India; email: manojgupta35@yahoo.co.in; A. Nanthaamornphong; Prince of Songkla University, Phuket Campus, College of Computing, Phuket, 83120, Thailand; email: aziz.n@phuket.psu.ac.thA vital issue faced by the distribution network is the occurrence of unintentional islanding. The failure to identify unintentional islanding results in significant implications for both the power system and human lives. In this paper, a novel machine learning islanding detection method (IDM) based on image classification utilizing the histogram of oriented gradient (HOG) feature is proposed. In particular, the set of parameters are utilized, namely total harmonic distortion (THD) of both three phase currents and voltages, and rate of change of negative sequence voltage, are first transformed into time-frequency representations (i.e., spectrograms via the short time Fourier transform, and scalograms through continuous wavelet transform). Then, the HOG features are extracted from these images and used to train the machine learning (ML) algorithms to distinguish between occurrences of islanding and non-islanding events. Performance metrics including F1 score, recall, accuracy, precision and misclassification error are employed in the assessment process. Numerical results show that our image-based detector achieves faster detection times and higher detection accuracy versus state-of-art methods, thus confirming the validity of such approach for identifying islanding events. © 2013 IEEE.Item In vitro Antioxidant, Anti-Inflammatory, and Wound Healing Properties of Aloe Vera Infused with Canola Oil for Possible Application in Skin Cosmetics(Research and Development Institute Suan Dusit University, 2025) Khwunjit Itsarasook; Piyanuch Prompamorn; Jittarawadee Tanghiranrat; Amornrat Srisukong; Orapin Komutiban; Woraphot Haritakun; Kanlayaporn Chantree; K. Itsarasook; Department of Chemistry, Faculty of Science, Ramkhamhaeng University, Bangkok, 10240, Thailand; email: Khwunjit.its@hotmail.comThis research investigates the antioxidant, anti-inflammatory, and wound-healing properties of Aloe vera oil, along with its cytotoxic effects on normal human dermal fibroblasts (NHDF), particularly in the context of its potential use as a natural antioxidant in skincare formulations. A. vera oil was extracted using an infusion method with canola oil, and its properties were thorough characterized. The concentration of aloin and cycloartenol in the A. vera oil were measured using high-performance liquid chromatography (HPLC). The resulted indicated that A. vera oil exhibited no cytotoxicity towards NHDF cells. Additionally, the oil demonstrated antioxidant activity, as evidenced by its ability to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, and its reducing potential assessed through free radical scavenging activity (FRAP) assays. Regarding its anti-inflammatory properties, the A. vera oil at a specific concentration showed no cytotoxic effects on RAW 264.7 macrophage cells. Notably, its potent anti-inflammatory effects significantly (p<0.05) reduced nitric oxide (NO) productions in RAW 264.7 macrophage cells stimulated by lipopolysaccharide (LPS), compared to the LPS-treated cells group. Moreover, NHDF cells treated with A. vera oil exhibited a statistically significant (p<0.05) improvement in wound closure area in a scratch wound assay, indicating enhanced cell migration. Collectively, these findings highlight the antioxidant, anti-inflammatory, and wound-healing properties of A. vera oil, underscoring its potential as an eco-friendly and beneficial ingredient for cosmetic skincare products. © 2025, Research and Development Institute Suan Dusit University.

The existence results were derived using the semi-group theory, measures of non-compactness, and the fixed-point theory in the sense of Arzelà–Ascoli theorem and Schauder’s fixed-point theorem. We analyzed the controllability results of the proposed problem by incorporating the ideas of semi-group theory and fixed-point techniques. The Banach contraction principle was used to derive the uniqueness and controllability of the proposed problem. We provide an example to support the theoretical results. © 2025 the Author(s), licensee AIMS Press.Item Improving Fire Extinguishing Properties of Class B Fire with Cellulose-Hydrogel from Water Hyacinth (Eichhornia crassipes) Extract(Faculty of Engineering, Universitas Indonesia, 2025) Surachat Sinworn; Nuttabodee Viriyawattana; N. Viriyawattana; Department of Occupational Health and Safety, Faculty of Science and Technology, Suan Dusit University, Bangkok, Bangplad District, 10700, Thailand; email: nuttabodee_vir@dusit.ac.thCellulose can be processed into a hydrogel that enhances performance in extinguishing Class B (oil) fire. This hydrogel has a significant increase in viscosity after exposure to high temperatures. As the temperature increases, the viscosity rises, enhancing the ability of hydrogel to coat the fuel surface and effectively prevent the production of flammable vapor. Therefore, this study aimed to synthesize cellulose-based hydrogel by extracting water hyacinth to obtain cellulose in the form of methylcellulose (MC) powder. Properties of cellulose hydrogel were tested using Fourier Transform-Infrared Spectrometer (FT-IR), Scanning Electron Microscope (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), viscosity, Thermogravimetric Analysis (TGA), and gel fraction analysis. To define its performance, fire extinguishing efficiency tests were performed by comparing mono-ammonium phosphate (MAP) or ABC (control) and MAP+ cellulose hydrogel (treatment). The data obtained were the radiation temperature, the time required to extinguish fire, and characteristics of the fuel coating during combustion. The results showed that fire extinguishing performance for Class B fire, in terms of radiation temperature, was lower for MAP+cellulose Hydrogel at 284.67±39.28°C, compared to MAP at 368.10±51.46°C. Extinguishing time for the MAP+ Cellulose Hydrogel was 4.19 seconds faster than only MAP. Additionally, the coating properties improved as the substance transitioned from powder to gel, effectively coating the fuel at high temperatures. This was consistent with the results of the Gel Fraction Analysis and TGA, which prevented fire spread and improved flame retardancy. © (2025), (Faculty of Engineering, Universitas Indonesia).
