Low temperature is an easy technique which preserves and retains product quality. The objectives of this research were to develop the Trang local roasted pork pieces into cookies and to study the effect of chilling and freezing of cookie dough on cookie quality. The methodology of research was conducted by studying 3 different levels (25%, 50% and 75%) of dry roasted pork suitable to be cookie and study the cookie properties: microbiological and physical quality. The results of this research indicated that addition of dry roasted pork into cookie dough at 50% level received the highest sensory score for all aspects. The 50% dry roast pork cookie dough was studied regarding chilling and freezing storage condition, and determined color, spread ratio and textural quality. The color parameters were determined through lightness (L*), redness (a*) and yellowness (b*) values of both cookie dough models stored under chilling and freezing and the results showed that these values increased with increasing retention time. In terms of cookie color from chilling and freezing cookie dough, it was found that L* and a* decreased but b* was unchanged. The spread ratio for both cookies from chilling and freezing dough decreased, the spread ratio of freezing dough was lower than chilling dough. When cookieÕs textural quality was investigated, hardness value from both chilling and freezing cookie dough increased after week 2 and increase rate continued until week 6. In addition, the chewiness value increased for both cookies from chilling and freezing dough. The fracturability of cookies from chilling and freezing dough slightly increased after 6-week storage. Crispiness value of both cookies from chilling and freezing dough were stable as early as 2 weeks and continually increased until last storage time at week 6. © 2021, Research and Development Institute Suan Dusit University.

(Nova Science Publishers, Inc., 2021) Glenn Baxter; Panarat Srisaeng; G. Baxter; School of Tourism and Hospitality Management, Suan Dusit University, Huahin Prachaup Khiri Khan, Thailand; email: g_glennbax@dusit.ac.th
Sustainable waste management is increasingly being adopted by airports as a key part of their environmental sustainability strategies. Each year airports generate large quantities of wastes, which include both hazardous and non-hazardous wastes, all of which require careful handling to minimise their adverse impact on the environment. This study uses annual wastes data from 2008 to 2017 to examine how Frankfurt Airport, a major global air transport hub, manages its general (non-hazardous) and hazardous (toxic) wastes. Findings indicate that throughout the study period, Frankfurt Airport principal waste management strategy was the reclamation of wastes for recycling wherever possible. This is evident in the annual total wastes recoverability rate increasing from 83% in 2008 to 90.3% in 2017. Wastes that cannot be recycled are separated out and reusable materials are recycled or transported to regional waste-to-energy plants. Electricity and district heating are extracted from the energy that is produced from the incineration process. Hazardous wastes are collected separately, and such wastes are channelled away for recycling as far as possible. Where recycling is not possible, hazardous wastes are disposed of in approved incineration or in physical and chemical treatment plants. An important finding of the study is that the number of passengers using Frankfurt Airport throughout the study period increased significantly. Despite this strong growth in passenger traffic, Frankfurt Airport was able to reduce the waste per enplaned passenger from 0.45 kgs in 2008 to 0.32 kgs in 2017. A similar trend was found in relation to the waste per workload unit (WLU) which decreased from 0.34 kgs per WLU in 2008 to 0.24 kgs per WLU in 2017. The annual waste per aircraft movement also decreased over the study period from 49.63 kgs per aircraft movement in 2008 to 42.81 kgs per aircraft movement in 2017. Importantly, no wastes are disposed to landfill by the airport, as this waste disposal method has adverse impacts on the environment. © 2022 by Nova Science Publishers, Inc. All rights reserved.
Effects of Nutrient Supplement and Chitosan on Microbial Population Change in Up-Flow-Anaerobic-Sludge-Blanket Reactor during Biogas Production
(Research and Development Institute Suan Dusit University, 2021) Rungroj Piyaphanuwat; Srisuda Samaimai; Vassanasak Limkhuansuwan; V. Limkhuansuwan; Faculty of Science and Technology, Suan Dusit University, Bangkok, 10700, Thailand; email: vassanasak_lim@dusit.ac.th
The objective of this research was to study the effects of nutrient supplement and chitosan on microbial change in an up-flow-anaerobic-sludge-blanket (UASB) reactor during biogas production. Three UASB reactors were operational in this study. All reactors were operated by feeding dilute stillage with chemical oxygen demand (COD) concentration at 10,000 mg/L and 9 days of hydraulic retention time (HRT) under anaerobic conditions. Reactor 2 and reactor 3 were supplemented with nutrient supplement and chitosan, respectively. The results of the environment and pH values of all UASB reactors showed similar conditions with total volatile acid/ alkalinity (TVA/Alk) values of 0.27-0.31. The COD removal efficiency of reactor 1 (stillage), 2 (stillage and nutrient supplement) and 3 (stillage and chitosan) showed about 79%, 84% and 87%, respectively. In addition, it was found that the UASB reactors supplemented with nutrient supplement or chitosan produced higher levels of biogas than those without additives. The 16S rRNA technique by PCR reaction showed that the dominant archaea in the final fermentation of all UASB reactors and in inoculum sample were hydrogenotrophic (genus Methanobacterium) and acetotrophic methanogens (genus Methanosaeta). The methanogens population in the reactor supplemented with chitosan (18.11%) produced more biogas than the ones in the reactor supplemented with nutrient supplement (14.44%) and in the control reactor (15.95%). © 2021, Research and Development Institute Suan Dusit University.

An Investigation of the Language used on Signage in Japanese Town on Sukhumvit Road, Bangkok through the Lens of Linguistic Landscape
(Research and Development Institute Suan Dusit University, 2021) Gornkrit Meemongkol; Sutsawad Jandum; G. Meemongkol; International College for Sustainability Studies, Srinakharinwirot University, Bangkok, 10110, Thailand; email: gornkrit@g.swu.ac.th;
This study investigates the language diversities and Japanese language usage reflected on the signage found in Japanese town on Sukhumvit Road, Bangkok. A qualitative research method was used, with which samples were collected by taking fifty photos of signage along five alleys on Sukhumvit Road with Japanese script appearing on them. The framework of Landry & Bourhis (1997) was employed in this study. The results show that Japanese has an important role in the multilingual area of Sukhumvit Road whereas English was used as the international language. Moreover, Thai language appeared on the signage as the national language but English was still the main language used to communicate with the target customers of various nationalities. It is inferred that most people in the area understand everyday English well. Additionally, the signage of Japanese restaurants was the most prominent and most of them represent Japanese culture. In addition, horizontal text was evident in the system of writing. This may be influenced by the Thai writing system as well as the Western languages. Furthermore, Kanji scripts were the most used on the signage compared to Hiragana and Katakana scripts. Overall, Kanji, as the picture scripts of Japanese language, may convey the meaning of lexical words to readers effectively. © 2021, Research and Development Institute Suan Dusit University.

(Research and Development Institute Suan Dusit University, 2021) Suwanna Pichaiyongvongdee; Tita Foophow; Piyawan Yoodee; Nujira Rasamipaiboon; S. Pichaiyongvongdee; School of Culinary Arts, Suan Dusit University, Bangkok, 10700, Thailand; email: suwanna_pic@dusit.ac.th
Pomelo (Citrus grandis (L.) Osbeck) is the largest citrus fruit in Thailand, which pomelo juice is commercially produced during the pomelo juice extraction process. After extraction of the juice, the number of by-products that was produced could be a potential source of functional dietary fiber.The objective of this study was to evaluate extraction methods of dietary fiber from pomelo juice byproducts for functional foods and particle size distribution (150, 180, 250 and 425 _m) by pomelo pulp powder (PPP) that was prepared by simply air drying, milling, sieving and grinding. For pomelo pulp dietary fiber powder (PPDFP), the PPP was treated with NaOH and ethanol to remove protein and fat, respectively. After that, analysis of physicochemical and functional properties of PPP and PPDFP found that the PPDFP was richer in total dietary fiber (92.04%), especially insoluble dietary fiber (91.93%). Water holding capacity (WHC) and oil holding capacity (OHC) of PPDFP were higher than those of PPP. Components that can contribute to the bitter flavor of the powders, limonin, naringin and naringenin were considerably reduced in PPDFP, particularly limonin was totally eliminated. Also, the porous structure of PPDFP may facilitate its use in food processing compared to the more sheet-like structure of PPP. The optimum particle size was 150 _m that resulted in powders with increased WHC and OHC. From the above data, it was concluded that the PPDFP was a good source for food dietary fibers that could be used as a functional ingredient in fiber rich food products. © 2021, Research and Development Institute Suan Dusit University.

(MDPI AG, 2021) Siwarit Pongsakornrungsilp; Pimlapas Pongsakornrungsilp; Theeranuch Pusaksrikit; Pimmada Wichasin; Vikas Kumar; P. Pongsakornrungsilp; Department of Tourism and Hospitality Industry, School of Management, Walailak University, Nakhon Si Thammarat, 80160, Thailand; email: kpimlapa@wu.ac.th
The purpose of this study was to explore how a regional brand can be co-created among different cities by employing the concept of place branding and brand culture. The Andaman Tourism Cluster of Thailand (ATC) generates the most tourism revenue in Thailand. Developing a regional brand identity can strengthen the competitive advantage of the ATC. Data were collected using multi-method research through questionnaires, projective techniques, and focus group inter-views. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were analyzed using thematic analysis. This study also shows that multi-method research contributes to brand management by facilitating collaboration, participation, and brand congruence among stakeholders. Quantitative and qualitative data were synthesized in order to develop the brand identity of the ATC. Focus group interviews were also employed to co-create the regional brand identity as ÔIrresistible AndamanÕ, of which sustainable tourism management is a fundamen-tal aspect. This study demonstrates how multiple sub-brands with different stakeholders can be integrated into a single regional brand. Moreover, stakeholders should focus on internal branding by communicating with all stakeholders to co-create brand congruence. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

The existence of solutions of nonlocal fractional symmetric Hahn integrodifference boundary value problem is studied. We propose a problem of five fractional symmetric Hahn difference operators and three fractional symmetric Hahn integrals of different orders. We first convert our nonlinear problem into a fixed point problem by considering a linear variant of the problem. When the fixed point operator is available, Banach and SchauderÕs fixed point theorems are used to prove the existence results of our problem. Some properties of (q, _)-integral are also presented in this paper as a tool for our calculations. Finally, an example is also constructed to illustrate the main results. © 2021 by the authors.

Bioactive compounds and antioxidant and enzyme inhibition activity levels were evaluated for three plants in the Zingiberaceae family in Thailand. Quantification of the phenolic and curcumin contents revealed that the largest component of all extracts was phenolic compounds (213.16-317.64 mg/g extract). The major curcuminoids in Curcuma longa L., Curcuma aromatica Salisb. and Zingiber montanum (J.Koenig) Link ex A.Dietr. were bisdemethoxycurcumin (BDMC; 27.31 mg/g extract), curcumin (16.59 mg/g extract), and curcumin (0.12 mg/g extract), respectively. The extracts from C. longa, C. aromatica and Z. montanum all showed antioxidant activity that was assessed using 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl (DPPH¥) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS¥+) radical scavenging assay. In addition, all extracts had copper chelating activity of more than 50%, with the extract from C. longa having the highest chelating activity (76.45%). All extracts from the three plants inhibited tyrosinase and elastase activity with half maximal inhibitory concentration values of 290.33-1,373.68 µg/mL and 69.61-3386.23 µg/mL, respectively. In addition, collagenase inhibition activity was observed in all extracts. The findings from this study showed that extracts from C. longa, C. aromatica and Z. montanum have potential antioxidant activity and can act as anti-tyrosinase, anti-collagenase and anti-elastase agents. The extracts could be further applied in cosmeceuticals as an active ingredient for anti-aging products. © 2021 Elsevier B.V.. All rights reserved.

(Research and Development Institute Suan Dusit University, 2021) Pornchanit Kaew-Nate; P. Kaew-Nate; Faculty of Management Science, Suan Dusit University, Bangkok, 10300, Thailand; email: Pornchanit_dusit@ac.th
This article is a study to highlight that digital transformation is something that businesses cannot avoid. However, the transition is not just about adopting the technology. The organizational leaders must also understand that the condition for transitional success is a harmonious change of people, systems, and contexts. This academic paper studies three issues: 1) Concept of Digital Thailand 2) Concept of Digital transformation 3) Promotion of personnel in organizations to have skills and digital culture. The study shows that digital transformation can be successful if important aspects are implemented. The principle aspects are the self-review of the organization from the vision, strategy, operational processes and value delivered to the customer as well as determining where the organization is in the digital age industry to see why there are operational delays and, most importantly, to see the qualifications of organizational leaders who need to understand digital transformation. All of this is the corporate culture in the digital transformation era, not just buying or importing technology into the organization without considering other elements. However, the definition of the word ÒDigital cultureÓ is also diverse. In this academic article, it is used to define the meaning of ÒDigital cultureÓ which refers to a modern corporate culture that focuses on changing the work and way of thinking of the people in the organization. © 2021, Research and Development Institute Suan Dusit University.

(International Journal of Criminal Justice Sciences, 2021) Pemika Sanitphot; Sunee Kanyajit; Patchara Sinloyma; Thanapat Patchim; P. Sanitphot; Mahidol University, Thailand; email: sapemika2524@gmail.com
This research aimed to explore the police operations enacted in relation to the prosecution of children in Thailand, utilizing both quantitative (through a questionnaire completed by 325 respondents) and qualitative (through in-depth interviews conducted with 20 respondents). The sample constituted police officers, judges, public prosecutors and psychologists/social workers with experience in the prosecution of children. The research findings revealed that police officers in Thailand lacked knowledge and experience in relation to the prosecution of children, with regards to the pertinent legal provisions as well as prosecution principles which existed in this region. Furthermore, a standard operating procedure and a set of prosecution guidelines were also not being followed by the Thai police officers. These initiatives, if taken, would improve the capabilities of Thai police officers. Additionally, the current research also provided a model of standards for law enforcement entities to follow in the prosecution of children and juveniles in Thailand © 2021 International Journal of Criminal Justice Sciences.

(Blackwell Publishing Ltd, 2021) Naratip Poonnakasem; N. Poonnakasem; School of Culinary Arts, Suan Dusit University, Bangkok, Thailand; email: pomac116@hotmail.com
The objectives of this research were to study the effect of concentration of egg white and air temperature on physicochemical properties and the effect of packaging on the moisture during storage of foam mat dried chili sauce powder. Results demonstrated that 6% (wt/wt chili sauce basis) egg white as foaming agent and drying temperature at 80¡C to produce chili sauce powder were the optimum condition that led to higher foam expansion, yield percentage, and water solubility, and lower moisture content, Aw, and bulk density. For microbiology test, total viable count, yeast and mold, coliform, and E. coli followed a Thai community product standard of seasoning powder. Plots of moisture content of product in all types of packaging versus time were linear model. The best packaging that could protect moisture permeability was aluminum foil laminate. According to the shelf life prediction, the product in packaging could be stored for 13Êmonths. Practical applications: Chili sauce (hot sauce) is one of the most famous products processed from chili and can be added to many kinds of foods. Application of foam mat drying for this product can extend its shelf life and increase product variety for consumers. The optimum condition for production of chili sauce powder is 6% egg white as foaming agent and drying temperature at 80¡C. The kinetic modeling can be applied for tracking moisture changes of products. The best packaging that could protect moisture permeability was aluminum foil laminate that can be used to store the product for 13Êmonths. This research can be benefit the industrial sauce production for better distribution of the products. © 2021 Wiley Periodicals LLC.
