Rooymai; Faculty of Management Science, Suan Dusit University, Bangkok, 10300, Thailand; email: ajarnsandy@hotmail.comThis research had two aims, (1) to determine information sources influencing inbound touristÕs perception on the ideal image of Thailand (images of Thailand before visiting) and (2) to compare between ideal and perceived images (images of Thailand after travelling). Data was gathered from 400 inbound tourists who had experiences in travelling in Thailand. Selection of respondents of inbound tourists, by accidental sampling at Suvannabhum Airport 250 respondents and at Don Muang Airport 150 respondents. The research tools used in the study were structured questionnaires. The statistics for test the hypothesis ÒThe ideal and perceived image of Thailand is significantly differentÓ is a t-test. The study findings are as follows 1. The majority of respondents were mostly female, single and aged under 30 years old. Most respondents had Bachelor Degree in Education, were professional employees and earned income less than 20,000 US$ per year. The dominant characteristics are western (England, Germany, Russia, Sweden, Norway and Australia, respectively), spending from 10 to 20 days in Thailand, travelling alone, and their visit was mainly influenced by the nature and climate. Furthermore, most of them claimed the significant sources of Thailand information were their friends and social media, respectively. The social media they accessed regarding Thailand information, they mainly mentioned websites i.e., www.lonelyplanet.com and www. tripadvisor.com, respectively.Travel public relations agencies most used personal media or word of mouth, followed by social media especially the website www. lonelyplanet.com and www.tripadvisor.com.(2) Most respondents positively perceived ideal images of Thailand and reported positive perceived images of Thailand with very good level in all aspects. Significantly, the various kinds of food was given the highest score of both ideal and perceived images of Thailand. (3) The comparison between ideal images and perceived images of Thailand reveals that after travelling the scores given to an aspect of various kinds of food decreased, while the highest scores were given to an aspect of natural resources and environment. (4)The hypothesis test showed the difference in ten aspects between ideal images and perceived images of Thailand including aspects of natural resources and environment, safety of places, various kinds of food, excellence of hotels, worthiness of shopping, reasonability of service prices, information for travel, residential information, discounts for travel, and information publication for tourists by agencies and/or government organizations. © 2022, Research and Development Institute Suan Dusit University.

Panichakul; Faculty of Science and Technology, Suan Dusit University, Bangkok, 10700, Thailand; email: tasanee_p@yahoo.comThe aim of this study was to investigate the effectiveness of developing a roll-on deodorant that can reduce armpit microbiota bacteria to decrease armpit odor. The richest apocrine sweat glands in the armpit region secrete a variety of odor precursors that are transformed into volatile odoriferous substances by bacterial enzymes on the skin surface. The dominant armpits microbiota included four groups of bacteria such as Staphylococcus spp., Micrococcus spp., Corynebacterium spp., and Propionibacterium spp., and also fungi or yeasts. Two formulas of the roll-on deodorant products, RDEOF-1 and RDEOF-2 were developed. RDEOF-2 contained an ethanolic extract of Rhinacanthus nasutus (L.) Kurz leaves inhibited several microorganisms, including Gram-positive and Gram-negative bacteria. Sixteen healthy volunteers showed satisfactory assessment for RDEOF-2 that was greater than RDEOF-1. Armpit bacteria were collected by swab method and armpit odor was evaluated by ASTM method. Results showed dominant bacteria of two genera including Staphylococcus spp. and Corynebacterium spp. in all swab samples that mainly cause armpit odor. Armpit bacterial numbers before using deodorants were high in the range of 2x103 to 9x105 (CFU/mL). After applying RDEOF-1 and RDEOF-2, bacterial numbers decreased in the range of 1x103 to 8x105 and 3x102 to 4x105 (CFU/mL), respectively. Armpit bacteria were found in males more than in females. Deodorant products containing R. nasutus extract have been shown to reduce the bacteria that cause armpit odor. Therefore, the development of the deodorant product with natural plant extracts is warranted. © 2022, Research and Development Institute Suan Dusit University.

Sitthiwirattham; Mathematics Department, Faculty of Science and Technology, Suan Dusit University, Bangkok, 10300, Thailand; email: thanin_sit@dusit.ac.thIn this study, we intend to investigate the steady-state and laminar flow of a viscous fluid through a circular cylinder fixed between two parallel plates keeping the aspect ratio of 1: 5 from cylinder radius to height of the channel. The two-dimensional, incompressible fluid flow problem has been simulated using COMSOL Multiphysics 5.4 which implements finite element's procedure. The flow pattern will be investigated by using the Reynolds number from 100 to 1000. The reattachment length formed at the back of the cylinder and drag force when the fluid comes to strike with the front surface of the cylinder is expressed in terms of Reynolds numbers. We propose to calculate the velocity and the pressure before and after the cylinder. For this purpose, two-line graphs before and after the cylinder will be drawn to check the impact of cylinder on both velocity and pressure. It was found that the percentage change in the velocity as well as pressure before to after the cylinder is changing their behaviours at Re = 700. The study is important because the empirical equations between the vortex's lengths formed along the cylinder using the linear regression process obtained in this study may be used for future implementation. © 2022 Abid.

Nonlaopon; Department of Mathematics, Faculty of Science, Khon Kaen University, Khon Kaen, 40002, Thailand; email: nkamsi@kku.ac.thIn this paper, we establish some new Newton's type inequalities for differentiable convex functions using the generalized Riemann-Liouville fractional integrals. The main edge of the newly established inequalities is that these can be turned into several new and existing inequalities for different fractional integrals like Riemann-Liouville fractional integrals, k-fractional integrals, Katugampola fractional operators, conformable fractional operators, Hadamard fractional operators, and fractional operators with the exponential kernel without proving one by one. It is also shown that the newly established inequalities are the refinements of the previously established inequalities inside the literature. © 2022 Jarunee Soontharanon et al.Item Existence Solutions for Implicit Fractional Relaxation Differential Equations with Impulsive Delay Boundary Conditions(MDPI, 2022) Varaporn Wattanakejorn; Panjaiyan Karthikeyann; Sadhasivam Poornima; Kulandhaivel Karthikeyan; Thanin Sitthiwirattham; T.

Tea and the Effects of Brewing Time on Color, Volatile Compounds, Chemical Compositions and Sensory Quality(Research and Development Institute Suan Dusit University, 2022) Dudsadee Sapbua; Chalida Cholmaitri; D. Sapbua; School of Culinary Arts, Trang Center, Suan Dusit University, Trang, 92130, Thailand; email: dudsadee_sap@dusit.ac.thThe torch ginger tea made from flower of Etlingera elatior (Jack) R.M. Smith. It is a type of herbal tea (tisanes) with health benefits. The composition of volatile aroma compounds is one of the factors which induce relaxation and charming scent. The purpose of this study was to profile volatile compounds of the torch ginger tea and quality on physical, chemical, and sensory properties of torch ginger tea. The torch ginger tea infusion was prepared by adding 2 and 5 g of torch ginger tea into 100 ml of hot water (95¡C) infused for 5 and 10 min and is effected by quantity and brewing time. Results showed that volatile compounds of the dried petal of the torch ginger had the highest abundance that included _-pinene, 1-dodecanol and dodecanal, respectively. The odor description were fresh, sweet, pine earthy and woody. Prolonged brewing time and enrichment quantity of the dried petal of the torch ginger decreased L*(lightness) values but increased positive a* (red) and positive b*(yellow) significantly (p < 0.05). 5 g torch ginger with 10 min brewing time had the highest chemical content consisting of the total phenolic content (206.42 mg GAE/100 g dry weight), the total anthocyanin content (0.887 mg/100 g dry weight), the ascorbic acid (0.602 mg/100 g dry weight) and DPPH (49.38 % inhibition) were significantly (p < 0.05). However, 2 g torch ginger with 10 min brewing time had the chemical content (the total phenolic, the total anthocyanin, the ascorbic acid and DPPH) as well as with the 5 g torch ginger tea with brewing time at 5 min. The sensory properties showed 5 g torch ginger tea with 10 min brewing time had high scores for color, flavor, taste and over all acceptance. Finally, 5 g torch ginger and 10 min brewing time was recommended as the best condition. © 2022, Research and Development Institute Suan Dusit University.

Srijuntrapun; Faculty of Social Sciences and Humanities, Mahidol University, Nakornpathom, Phuttamonthon 4 Rd., Salaya, 73170, Thailand; email: nisa_lay@hotmail.comAlthough food waste reduction has been recognized as an important method for managing the environment in the past, it has not received much attention from the hotel business sector. This article reveals that food waste hierarchy is an important strategy for hotels, as it helps them to reduce food waste at the generation point, while reducing food costs and protecting the environment. The process of food waste reduction can be holistically integrated with the distribution process. The study found that there were significant differences related with hotel size in the 7-step food distribution process. The mean distribution process of large hotels is higher than the one of medium and small hotels. The results also show that the hierarchy of food waste management motivates the hotel business sector to implement food waste reduction by ensuring that hotel operations achieve Corporate Social Responsibility (CSR) goals in the form of Creating Shared Value (CSV). The primary goal of CSR is to align corporate and social values. © 2022 The Author(s)Item Hydrodynamics and Heat Transfer Analysis of Airflow in a Sinusoidally Curved Channel(Tech Science Press, 2022) Abid A. Memon; M. Asif Memon; Kaleemullah Bhatti; Thanin Sitthiwirattham; Nichaphat Patanarapeelert; T. Sitthiwirattham; Mathematics Department, Faculty of Science and Technology, Suan Dusit University, Bangkok, 10300, Thailand; email: thanin_sit@dusit.ac.thFor heat transfer enhancement in heat exchangers, different types of channels are often tested. The performance of heat exchangers can be made better by considering geometry composed of sinusoidally curved walls. This research studies the modeling and simulation of airflow through a 2¹ units long sinusoidally curved wavy channel. For the purpose, two-dimensional Navier Stokes equations along with heat equations are under consideration. To simulate the fluid flow problem, the finite element-based software COMSOL Multiphysics 5.4 is used. The parametric study for Reynolds number from Re = 100 to Re = 1000 and the period of vibration P from 0 to 5 are observed. The surface plots, streamline patterns, contours, and graphs are presented for the velocity field magnitude, temperature, and pressure against the Reynolds number as well as period of vibration. The results are compared with various literature. It is found that due to the creation of periodic contraction regions the velocity magnitude of the flow is continuously increasing with the increase of Reynolds number, on the contrary the pressure is decreasing from inlet to outlet of the channel. Also, a periodic variation in the pressure distribution along the vibrating boundaries has been found with an average increase of 500% for the high Reynolds number. A novel work was done by expressing the rotation rate per second in terms of local Reynolds number for the recirculating regions found due to the periodic oscillation of the boundaries. The average temperature near the outlet where a fixed temperature is imposed initially is decreasing with an increase in Reynolds number. The convection process is weakened due to an increase of periodic vibration of boundaries. © 2022 Tech Science Press.

Pichaiyongvongdee; School of Culinary Arts, Suan Dusit University, Bangkok, 10700, Thailand; email: suwanna_pic@dusit.ac.thRice noodles are a widely consumed food in Asia, including in Thailand. Nevertheless, this popular food is high in carbohydrates, but low in dietary fiber. Pomelo by-products (PBP) are a highly insoluble dietary fiber (IDF) source that has been investigated for fiber-fortified rice noodles with health benefits. This study was conducted to prove the effects of IDF in PBP at different levels (10 and 12.5%) of the rice flour and different particle size distributions (180 and 150 _m) on the moisture content, water activity, cooking weight, cooking loss, textural and sensory evaluation. The addition of IDF-PBP to rice noodles was found to have significant (p<0.05) effects on the colors of a*, b*, while cooking weights were increased in all samples. Cooking loss and tensile strength also decreased as compared to the control. The moisture content and water activity of rice noodles were between 8.66-9.14% and 0.32-0.36, respectively. When considering the addition of IDF-PBP at 10 and 12.5%, the findings revealed that the sample was not significantly different (p>0.05) in the cooking weight. However, when the particle size was reduced, the cooking weight increased. Cooking loss decreased when IDF-PBP was increased, and the particle size was reduced. The texture of the particle size distribution was 180 and 150 _m at levels 10% in tensile strength and showed not significant difference (p>0.05) as compared to the control rice noodles. Rice noodles with 10% IDF-PBP particle size distribution 150 _m showed the highest overall acceptability in sensory evaluation. The results revealed that adding IDF-PBP to rice noodles increased the total dietary fiber content at 9.44% and the insoluble dietary fiber content at 8.71% as compared to the control rice noodles. Based on the results, the addition of IDF-PBP to rice noodles can lead consumers to conclude that the product is healthy. © 2022, Research and Development Institute Suan Dusit University.

Rezapour; Department of Mathematics, Azarbaijan Shahid Madani University, Tabriz, Iran; email: sh.rezapour@azaruniv.ac.irIn this paper, we conduct a research on a new version of the (p, q) -HermiteÐHadamard inequality for convex functions in the framework of postquantum calculus. Moreover, we derive several estimates for (p, q) -midpoint and (p, q) -trapezoidal inequalities for special (p, q) -differentiable functions by using the notions of left and right (p, q) -derivatives. Our newly obtained inequalities are extensions of some existing inequalities in other studies. Lastly, we consider some mathematical examples for some (p, q) -functions to confirm the correctness of newly established results. © 2022, The Author(s).Item Integration of Kouprey-Inspired Optimization Algorithms with Smart Energy Nodes for Sustainable Energy Management of Agricultural Orchards(MDPI, 2022) Pannee Suanpang; Pattanaphong Pothipassa; Kittisak Jermsittiparsert; Titiya Netwrong; P. Suanpang; Faculty of Science and Technology, Suan Dusit University, Bangkok, 10300, Thailand; email: pannee_sua@dusit.ac.thEnergy expenditure is now a major cost for agribusiness and community-based tourism in Thailand. Both types of businesses can also generate huge amounts of income for the country each year. This is a result of operators having to share part of their income with utility bills each month. As a result, the net return is lower than the operator should receive. Recognizing the need for energy management for sustainable use in agriculture focusing on durian cultivation in Kantharalak district and community tourism in Sisaket province, this research used a newly developed optimization algorithm called Kouprey-inspired optimization (KIO) to assist energy management in smart agriculture to support community-based tourism. This was initiated with a smart energy node to reduce the energy and labor costs for volcanic durian planting and accommodation in community-based tourist attractions in Sisaket province. The results showed that the combination of the KIO algorithm and smart energy node allowed for efficient management of the volcanic durian orchards and the use of clean energy in combination with traditional electric power for volcanic durian cultivation and community-based tourism. As the research area in Sisaket province had eight hours of solar power per day, this was sufficient for smart agriculture and community-based tourism in the daytime and in the evening. Furthermore, this allowed operators in both the agricultural and tourism sectors to reduce the labor costs of the durian orchard business and community-based tourism by about 30%, and in the energy sector, the costs could be reduced by 50%. As a consequence, this prototype would lead to the expansion and trial in durian orchards in the Eastern Economic Corridor area, which is an important economic area producing durian for export of the country. © 2022 by the authors.
