Authors:   , Parivatphun Nichakon 
Published: April 2023

With the increasing popularity of Korean idols in Thailand, it has become a trend among teenagers to follow their fashion, hair, and makeup. Korean Wave or Hallyu idols have become the object of envy of fans, and it is easy to find the behavioral trends of teenagers trying to imitate and follow their idols.

The purpose of this research is to explore the make-up behavior of Thai female fans influenced by BLACKPINK and analyze the reasons and motivations in following the make-up behavior of their idol. The Attitude/Motivation Test Battery (AMTB), developed by Gardner (1985), was used for measuring the degree of attitude and motivation of fans behavior.

Through this study, the following conclusion can be drawn. First, the influence of BLACKPINK’s make-up style on Thai female fans is at a high degree. Fans can form identity, can create confidence and can make friends when they have imitated BLACKPINK’s make-up behavior. Second, the results demonstrate that the high level of the influence from BLACKPINK’s fans due to their attitude to beloved idols is always good.
Metaphors in U.S. Same-sex marriage discourse: a corpus-based study
Authors:   , Amarinthnukrowh Pongbodin 
Published: April 2023

This research aims to investigate metaphorical patterns in the US legalization of same-sex marriage discourse to shed light on how metaphor is employed to conceptualize same-sex marriage controversies. To this end, a specialized corpus which contains 254 news articles published in 2015 was compiled. The metaphorical expressions in the corpus were analyzed with both “Conceptual Metaphor Theory” (CMT) and “Conceptual Blending Theory” (CBT) to cover not simply the pedestrian uses of metaphors, but also the wild and creative expressions. Specifically, while conventional metaphors were analyzed following the CMT traditions, novel metaphors were analyzed through the lens of blending. The results of this study show that the same-sex marriage controversy is construed primarily by 8 types of metaphors, namely the COMPETITION MF, the Location ESM, ontological, Building/Construction, Religion and the Supernatural, Crime, Light and Darkness, and Disease/Illness metaphors. The supporters of same-sex marriage utilize the COMPETITION MF to highlight social inequity and struggles the LGBT people are facing and empower one another, whereas the opponents use this type of metaphors to construe themselves as a protector of righteousness and construct the opposing side as a violent, harmful group of people. While the Location ESM is absent from the discourse of the opponents of same-sex marriage, it is employed by the supporters to highlight the struggle and efforts toward achieving worthwhile goals. Ontological metaphors function mostly as building blocks for more complex metaphorical expressions. The Building/Construction and the Religion and the Supernatural metaphors are mainly an extension of ontological metaphors. And the Crime, Light and Darkness, and Disease/Illness metaphors are utilized to add negative viewpoints toward the target concepts.
Processing of English passive construction in L1 Thai learners
Authors:   , Chantajinda Vatcharit 
Published: April 2023

The objective of this research study is to examine Thai learners’ comprehension of English passive sentences focusing on Thai thùuk-passives, which are usually found in adversative contexts (Po-ngam, 2008; Prasithrathsint, 2010) which are prototypical in thùuk-passives and can also be used in neutral contexts (Prasithrathsint, 2001, 2006), and on be-passives in English, which can be found in all contexts. This work classified English verbs into three types using adversity and naturalness in Thai thùuk-passives, namely Verb Type 1 (adversative and natural in Thai thùuk-passives, e.g., destroy), Verb Type 2 (non-adversative and natural in Thai thùuk-passives, e.g., buy), and Verb Type 3 (unnatural in Thai thùuk-passives, e.g., heal).

In EXPERIMENT 1, an acceptability judgment task (AJT) was employed to measure Thai learners’ comprehension of English passives after they finished reading each sentence. Twenty intermediate and twenty advanced learners participated in this experiment. A two-way ANOVA revealed that proficiency levels affected Thai learners’ acceptability of and they judged sentences with Verb Type 1 significantly more acceptable that those with Verb Type 2 and those with Verb Type 3. Moreover, sentences with Verb Type 2 were likely to be more acceptable than those with Verb Type 3. Positive transfer from L1 possibly helped Thai students accept Verb Type 1 more than the other two verb types.

In EXPERIMENT 2, a self-paced reading task (SPRT) was used to examine learners’ online comprehension of English passives. Twenty intermediate and twenty advanced learners participated in this experiment. A two-way ANOVA indicated that proficiency levels likely affected their reading times and they read sentences with Verb Type 1 faster than those with Verb Type 2. They, additionally, tended to read sentences with Verb Type 3 faster than those with Verb Type 2. Since Verb Type 1 is the most natural verb type in Thai thùuk-passives, positive transfer can be at work when learners read English passives, unlike Verb Type 2 which is non-prototypical. Additionally, they processed Verb Type 3 relatively fast since the sentences were atypical in L1.

In summary, Thai learners performed well when the stimuli sentences comprised Verb Type 1 in the two experiments. Adversity, moreover, played a crucial role in learners’ comprehension of English passives. In addition, language transfer was discovered to be more obvious in the advanced learners. This is possibly due to the fact that they were highly aware of dissimilarities between L1 and L2 passives. The patterns found in the two tasks focusing on different comprehension processes differed to some extent possibly due to task effects.
Factors influencing adoption and usage probability of automated parcel lockers
Authors:   , Thongkam Orawee 
Published: April 2023

The study proposes a model to predict probability to use Automated Parcel Locker (APL) in Bangkok by adopting Multiple Linear Regression. In addition, to help business to market to the right target and increase the intention to use, the study investigates factors influencing Intention to use APL by employing Structural Equation Model (SEM). The framework is developed based on Technology Acceptance Model (TAM) and other external factors. The questionaries were conducted for both methods with 718 observation and 500 responses, randomly selected.

The results show that variables best predict probability to use APL is price set with discount, followed by location of APL, travelling distance, and demographic factors (age, gender, education, occupation, and individual income). Moreover, from SEM analysis, it shows that Trialability has strong positive impact to Perceived Ease of use and Perceived Usefulness, which positively impact to Attitude and Intention to use respectively. However, it also found out that Transaction cost, Technology anxiety and Perceived control do not impact on Intention to use. For the last part of this study, the comparative analysis showed that if 10% of APL adoption is realized, 16% of carbon emission will be reduced based on given assumptions.
Variation of symbiodiniaceae in broadcaster acropora humilis and brooder pocillopora damicornis corals
Authors:   , Jandang Suppakarn 
Published: April 2023

Reef-building corals sustain a symbiotic relationship with single-cell algae belonging to family Symbiodiniaceae. Symbiotic algae contribute up to 50-95% of the metabolic needs by supplying photosynthetic products to the coral host. Therefore, the symbiosis between corals and Symbiodiniaceae is essential for the development and survival of coral reefs. Over the past years, significant losses and changes in coral reef ecosystems have been caused by anthropogenic activities and natural phenomena. Thus, relevant national organizations have raised awareness regarding the conservation of coral populations. Our Reef Biology Research Group, Department of Marine Science, Chulalongkorn University have been producing corals using a sexual propagation technique for coral reef rehabilitation since 2003. Nevertheless, studies on coral background, including their biology and adaptation mechanism, are required for policy and/or action plan of coral reef management and conservation. This study consisted of three experiments that aimed to collect the related information on corals, especially coral spawning, and investigate the diversity of Symbiodiniaceae in corals from the upper GoT. Two Acropora species spawn their gametes around 8 PM to 9 PM across all lunar periods with no clear indication of lunar-associated cue. According to year data, asynchronous spawning occurs and may lead to the low success of fertilization and the decreased number of coral recruitments (Experiment 1). A. humilis and P. damicornis exhibited the shuffling and switching of Symbiodiniaceae community under hatchery conditions. However, we recorded the association of Symbiodiniaceae genus Symbiodininium with coral, which has never been reported before in Thailand (Experiment 2). Tagged colonies of wild Acropora and Pocillopora corals showed a significant decline in zooxanthellae cells during summer, but the community of Symbiodiniaceae exhibited no change throughout the year (Experiment 3). The results from this study are useful for understanding the coral life cycle and coral-Symbiodiniaceae relationship, which can be applied to the prediction of potential adaptation of corals in localized reef environments and improve coral cultivation and conservation in Thailand.

Published: April 2023

In this thesis, we introduce the concept of a strictly stable fixed point of a selfmap and investigate the relationship among various types of fixed point stability. We prove that all fixed point of a quasi-nonexpansive map is strictly stable and extend the concept of a strictly stable fixed point of a selfmap to an iteration scheme. We introduce the concept of convexly strictly stable fixed points of selfmaps and apply it to obtain virtual stability of some well-known iteration schemes in a convex subset of a Banach space.

Authors:   , Liao Tingting 
Published: April 2023

Non-healing diabetic foot ulcers are the most common cause of lower extremity amputation. Drug combination treatment is the most recent emerging strategy in local treatment of diabetic wound. This study aimed to find out the combined effects and underlying mechanisms of combined Phyllanthus emblica Linn. (PE) and simvastatin (SIM) on diabetic wound in mice. Male BALB/C mice were divided into five groups: control group (CON+Vehicle), diabetic wounded group (DM+Vehicle, streptozotocin 45 mg/kg. i.p. daily for 5 days), diabetic wounded groups with daily treatment of 100%PE cream, 5%SIM cream, and 100%PE+5%SIM combined cream, w/v, for 4 days, 7 days and 14 days. Mice bilateral full thickness wound excision was made after diabetic mice model establishment. Wound tissue malondialdehyde (MDA) level, IL-6 protein level, number of infiltrated neutrophils, percentages of wound closure (%WC), percentage of capillary vascularity (%CV) and percentage of re-epithelialization (%RE) were analyzed. The results showed that PE and simvastatin combination treatment increased %WC significantly on day 14. PE and simvastatin combination treatment increased %CV significantly both on day 7 and day 14. PE and simvastatin combination treatment downregulated number of infiltrated neutrophils significantly on both day 4 and day 7. PE and simvastatin combination treatment has tendency to reduce IL-6 protein level in diabetic wound both on day 4 and day 7. Further, PE and simvastatin combination treatment reduced MDA content significantly on day 4. Moreover, increasement of %CV had a strong positive correlation (r=0.7136, p=0.0019) with %WC on day 7. These findings showed that topical application of PE and simvastatin combination treatment could enhance wound healing by upregulating VEGF protein level, angiogenesis, and wound closure based on the combined effects on inhibiting oxidative stress and inflammation in diabetic mice.
Developing a novel bioink from hyaluronic acid-alginate-silk fibroin (HA- Alg-SF) for cartilage 3D printing
Authors:   , Nguyen Truc 
Published: April 2023

In the development of a bioink for cartilage 3D printing, Hyaluronic acid (HA), Alginate (Alg) were modified into amine-hyaluronic acid (HA-NH2) and aldehyde alginate (Alg-CHO). Magnetic Nuclear Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR) confirmed the successful modification of HA-NH2 and Alg-CHO. The hydrogel HA-Alg was crosslinked as a result of Schiff's base reaction, between primary amines and aldehydes to form imine bonds. By varying volume ratios, the optimal hydrogel HA-Alg (5:5) exhibited its printability, biocompatibility, and functionality as a bioink for cartilage tissue. HA-Alg (5:5) was printable with a custom-made extrusion 3D printer, had slow degradation, shear-thinning behavior, supported cell viability, proliferation, and chondrogenic differentiation. To prove that HA-Alg could act as a platform for entrapment of macromolecules, Silk fibroin (SF) which is a biocompatible protein was loaded into HA-Alg formulation to develop HA-Alg-SF hydrogel. The results showed that HA-Alg-SF hydrogel adapted to 3D printing, and promoted cartilage tissue formation. The addition of SF did not compromise the printability and cell viability of HA-Alg-SF hydrogel comparing to HA-Alg hydrogel, which suggested that HA-Alg hydrogel could be an interpenetrating polymer network (IPN) for loading other proteins, and growth factors for further applications.

Published: April 2023

Alzheimer’s disease is the most common neurodegenerative; cause of dementia and trends to increase in elder society. There is still not cure. A new strategy development for treatment is needed. SORL1 is a major genetic risk factor associated with sporadic AD. It correlates with degrading amyloid beta (Aβ) by sorting to lysosome. SORL1 overexpression has been reported that reduce Aβ production. However, the molecular mechanism that regulate in neurons is still unclear. The purpose of this study is to generate an effective drug discovery platform for identifying molecules that can modulate SORL1 level in human neurons by using induced pluripotent stem cells (iPSCs) together with genome editing using CRISPR/Cas9 technology to generate human cortical neurons SORL1-EGFP reporter cells. Here, we demonstrated that we successfully generated SORL1-EGFP reporter iPSC cell lines which still retains pluripotency and when differentiates to cortical neurons in vitro, express EGFP at the location corresponding to the location of endogenous SORL1 and SORL1-EGFP could more expressed when induced by BDNF and cAMP. Moreover, we generated the activation SORL1 using CRISPR-on technique which highly specific to endogenous. The results indicated that sgRNASORL1 could activate and significantly increase SORL1 expression levels in human erythroleukemic cell line (K562). This model could advance our understanding of SORL1 regulation, mechanisms of neurodegeneration and the effective of SORL1 activated sgRNASORL1 might offer a platform to find new therapeutics for Alzheimer’s disease in further.

Published: April 2023

The exome sequencing study of cholangiocarcinoma (CCA) revealed SMAD4 mutation was frequently observed. The role of SMAD4 to cholangiocarcinogenesis as well as cell origin of CCA are not fully understand. According to current CCA model including cell lines and animal models, it still limited in resembling human cells and early event during carcinogenesis. The objective of this study was to study the role of SMAD4 signaling disruption in cholangiocyte progenitors. To clarify these questions, we used induced pluripotent stem cells (iPSCs) to differentiate into cholangiocyte organoids by using growth factors induction in this study. The result demonstrated that cholangiocyte organoids were revealed cholangiocyte progenitor potential to long-term propagate (>8 months) and cholangiocyte-associated genes including hepatocyte-like cell conversion capacity. Our findings indicated that cholangiocyte organoids could represent as modelling for further CCA study. Additionally, we generated inducible SMAD4 knockout iPSC for SMAD4 knockout study in cholangiocyte organoids by using CRISPR/Cas9. Loss of SMAD4 in cholangiocyte organoids significantly affected on proliferation capacity, DNA damage-induced radiation response as well as tubular morphogenesis of cholangiocyte progenitors. The knowledge of SMAD4 knockout in cholangiocyte progenitors will provide more understanding of early event mechanism during cholangiocarcinogenesis and beneficial to develop CCA model in further study.
Effects of thiosulfate in artificial seawater on corrosion behaviour of 25Cr-3Ni-7Mn-0.66N new duplex stainless steel
Authors:   , Vongsilathai Songkran 
Published: April 2023

In this research, the 25Cr-3Ni-7Mn-0.66N new duplex stainless steel (DSS) was fabricated by the vacuum arc re-melting (VAR) process, then deformed by hot-forging process, and subsequently heat-treated at 1250°C for 1 hr + water quenched + 1050°C for 1.5 hr + water quenched., based on the calculation of the phase diagram by Thermo-Calc software. The material characterisations and chemical compositions were examined by various methods. The corrosion behaviours of the new duplex in artificial seawater (ASW) after ASTM D1141 and in artificial seawater mixing with thiosulfate was studied at 25°C and compared with that of the 2205 standard DSS by electrochemical methods. The final microstructures are ferrite and austenite. The phase ratio of ferrite to austenite is 59:41. The secondary phases were not found in the new duplex grade. The electrochemical test results show that the corrosion behaviours of the new duplex grade were better than that of 2205 DSS in the ASW, but it was reversed in the acidified ASW mixing with thiosulfate. According to the Polarisation and Electrochemical Impedance Spectroscopy test results, it is found that the corrosion behaviours on both duplex grades were more deteriorated when increasing the thiosulfate concentration in the acidified ASW mixing with thiosulfate. The pitting resistance of ferrite is lower than that of austenite since the pit exhibits in ferrite. It is confirmed by the PREN16 calculation results of ferrite and austenite. The Mott-Schottky analysis showed the bi-layer structure of the passive film in both the ASW and the acidified ASW mixing with thiosulfate. The passive film structure consists of the p-type semiconductor inner layer and the n-type semiconductor outer layer. In the ASW, the densities of cation and anion vacancies in the inner and outer layer of new duplex steel are lower than that of 2205 DSS, respectively. However, in the acidified ASW mixing with thiosulfate, the densities of cation and anion vacancies in the inner and outer layer of new duplex steel are higher than that of 2205 DSS, respectively. The corrosion behaviours of two duplex grades in both the ASW and the acidified ASW mixing with thiosulfate were discussed based on the Pourbaix diagram and the Point Defect Model (PDM).

Authors:   , Praditpapha Athikhun 
Published: April 2023

Background: COVID-19 pandemic is a public health emergency of international concern with many countries affected including Thai. Due to the nature of the work, dental practitioner is a high-risk professional to contract the disease. Many studies were conducted to study the impact of the situation on mental health of both general population and health care personnel. However, there are scant data about the stress of Thai dental practitioner caused by COVID-19 and the associated factors.

Objectives: The primary aims of this study were to investigate the prevalence and level of stress, along with its risk/protective factors. The secondary aim was to investigate the impact of COVID-19 pandemic consequences on the stress of Thai dentists during the COVID-19 pandemic.

Materials and methods: In this cross-sectional study, a questionnaire was developed and distributed via social media from April 24 to May 5, 2020. Demographic, work-related, and financial and socioeconomic status were collected as predictors of stress. Self-administered Stress Evaluation Form-20 (SASEF-20) was used to capture the level of stress. Also, specific questions about COVID-19 were asked to help explore the pandemic’s impact on dentists' stress.

Results: Of 622 responses, 580 were included in the final analysis. Stress level and prevalence were relatively low (hypo-stress=30.17%, normal stress=49.31%). However, the impact of COVID-19 related issues on stress demonstrated a median score of 5.00-8.00 out of 10. The main factors associated with higher stress levels were being a Christian, accepting emergencies during the pandemic, facing increased living expenses, and having a negative cash flow. In contrast, factors associated with lower stress levels were older age, working within certain specialist domains, and having a positive cash flow.

Conclusion: This study revealed low stress prevalence and level among Thai dentists during COVID-19 lockdown. Age, religion, specialty, working status, and change in expenses and cash flow during the COVID-19 pandemic were identified as stress predictors.
