Structural Priming and the Acquisition of English Dative Constructions by L1 Thai Learners
Authors:   , Kongbang Jaturaporn 
Published: September 2023

The purpose of the present study is to examine whether structural priming can facilitate L1 Thai learners’ acquisition of English dative constructions, both English DO construction and English PO construction and to investigate whether different priming conditions have different learning effects on L1 Thai learners’ acquisition of English dative constructions. The first hypothesis states that the L1 Thai learners produce English dative constructions, both DO construction and PO construction, at higher rates after receiving the structural priming experiments. However, the similar structure, i.e. the English PO construction is used more frequently than the different structure, i.e. the English DO construction. The second hypothesis states that different priming conditions have different learning effects on L1 Thai learners’ acquisition of English dative constructions. That is, less intervening sentences between prime and target sentences contribute to the short-term learning effects, whereas more intervening sentences between prime and target sentences mediate the long-term learning effects on L1 Thai learners’ acquisition of English dative constructions. The participants were 90 Thai intermediate learners of English randomly divided into three different priming conditions groups: long-lag priming group (n=30), short-lag priming group (n=30) and no-lag priming group (n=30). Data were collected from a comprehension checking task, a preference assessment task, a priming task and an immediate post-priming picture description task.

Results showed that the L1 Thai learners of English showed a significant increase in their productions of English dative constructions after receiving the structural priming experiments, suggesting that the learners acquired the English dative constructions more effectively through structure priming. Thus, the first hypothesis was confirmed by the results. Moreover, the structural priming effects were found to persist over time, suggesting that structural priming can promote long-term production of the English dative constructions among the learners. However, different priming conditions did not have different learning effects because the learners across the three priming condition groups showed similar production rates of dative sentences. Thus, the second hypothesis was not confirmed by the results. Moreover, it was assumed that structural priming was a form of implicit learning process (Bock & Griffin, 2000). The findings of the study contributed to SLA with respect to structural priming and led to some pedagogical implications.

Published: September 2023

Coronavirus disease 2019 (COVID-19) still provides global public health issues although several vaccines and antiviral agents have been developed. Some patients experience severe conditions needed medical intensive care, and some are dead due to the failure of treatments. Therefore, identifying the key genes and underlying molecular mechanisms is necessary to discover precisely targeted drugs. Analysis of protein-protein interaction (PPI) networks provides invaluable information to find disease mechanisms and effective alternative drugs. Hence, PPI network analysis based on leukocyte transcriptomic profiles of severe COVID-19 collected from Gene Expression Omnibus (GEO) DataSets was proposed for this study. A network diffusion method called Laplacian heat diffusion (LHD) algorithm was performed to construct an immune-related PPI network (IPIN). Furthermore, several network centrality measurements can identify 23 key genes from the IPIN. Subsequently, drug-gene interaction networks were constructed using database searching based on the key genes. There were 5 candidate drugs having the potential effect of interacting with the key genes. To find additional key genes and candidate drugs, two different leukocyte transcriptomic datasets were combined for the common PPI network construction. Centrality measurement and survival analysis were used to find and validate the further key genes. The analysis revealed 4 common key genes. The drug-gene interaction and molecular docking technique provided 2 further candidate drugs that interacted with the key genes. Additionally, miRNA-mRNA regulatory networks were built based on the PPI network to recognize 5 novel biomarkers for severe COVID-19 prediction. In conclusion, PPI network analysis can discover candidate biomarkers and drugs to predict and treat severe COVID-19 patients.
Developing a model for the integration of Bajau traditional ecological knowledge in the management of locally managed marine area: a case study of Wakatobi regency, Indonesia
Authors:   , Ariando Wengki 
Published: September 2023

Attaining sustainable resource management encompasses multilevel challenges and interdisciplinary approaches from grassroots efforts to international agreements. In the context of coastal and marine management, the complexities represented by the variety of local entities, regimes, and institutional supports are captured as current challenges in sustainability efforts. Such challenges, unfortunately, persist in the group of customary communities such as those of the Bajau, who live in coastal and marine areas. In an effort to address the aforementioned challenges, this research proposes a model for integrating the Traditional Ecological Knowledge (TEK) of the Bajau into Locally Managed Marine Areas (LMMA) scheme in Wakatobi, Southeast Sulawesi. A qualitative approach involving multi-sited ethnography and interviews was employed in this study. TEK as a concept is drawn upon to strengthen the local practices for sustainable resource use and therefore develop policy recommendations. However, in the case of Bajau communities, the dimensions of the TEK encompass conservation practices, ethno-fisheries, cultural beliefs, customary laws, weather and cultural astronomy, and adaptive management. The manifestation of the TEK needs to add the term 'exchange knowledge' due to the history and nature of former nomadic groups that interacted and exchanged knowledge and goods with other groups with whom they were in contact. Intercultural relations between the Bajau and dominant customary groups in Wakatobi position the Bajau as migrants and second-class people, both socio-culturally and in the context of various conservation activities. The co-management programs that involve the Bajau do not seem to consider the basic needs and practices of this group in current sustainable resource management. This situation indirectly contributes to the marginalization and growing development threats for the Bajau in Wakatobi. In addition, the complexities in the realm of contemporary Bajau society are not adequately considered in Wakatobi's development priority programs. The culturally inclusive projects and LMMA model do not engage Bajau communities, even though this group is pivotal in nurturing marine ecology in alignment with multiple TEK practices and a maritime culture orientation. In brief, the output model of this research examines the various terms to disentangle the challenges in cultural identity, intellectual property and rights, capacity building, livelihood diversification, and communal space in the Bajau communities in Wakatobi. In advance of making recommendations to implement the model, this research explored key attributes related to Bajau customary institutions, local government, and Wakatobi National Park.
Do issuers affect derivative warrants overpricing? evidence of Thailand
Authors:   , Thupthong Sarunporn 
Published: September 2023

Derivative warrants have become increasingly popular in many countries. However, numerous literatures provide the empirical evidences that derivative warrants are overpriced relative to the comparable options. Many researchers found that the derivative warrant overpricing can be explained by hedging cost, liquidity premium, market power, and asymmetric information of investors. These explanations are likely to be related to characteristics of derivative warrant issuer. Therefore, this paper comes up with the objective to reconfirm the overpricing phenomenon in Thailand and investigate the issuer identity effect on the derivative warrant overpricing as well as examine what issuer’s characteristics cause the level of overpricing differ across issuers. The results demonstrate that Thai derivative warrants tend to be overpriced and the nature of the overpricing phenomenon has changed due to the SEC revised disclosure regulation and the underlying market conditions. Furthermore, the results also show the existence of issuer identity effect on the overpricing level. The overpricing level is different across issuers and ranging from 2.77 to 66.15 percent. The findings can be explained through the issuer’s characteristics, namely, market share of issuer, credit risk of issuer, foreign issuer, and style of calculating time decay.
Diversification benefits of commodity indices versus Islamic stock indices
Authors:   , Khan Sita 
Published: September 2023

The objective of this study is to investigate conditional correlations between the Dow Jones Emerging Market index and commodity indices (i.e., agriculture, energy, industrial metals, livestock, precious metals) and Islamic stock indices (i.e., JKII, KLFTEMSI, MSCI Bahrain, MSCI Kuwait, and MSCI Qatar). Additionally, this paper classifies the properties of assets whether it is a diversifier, a hedger, or a safe-haven assets to the Dow Jones Emerging Market index. The estimation method is the dynamic conditional correlation generalized autoregressive conditional heteroskedasticity (DCC-GARCH) model to estimate the conditional correlations during the period of 2007-2021 which covers the Global financial crisis (GFC) and Covid-19 pandemic. The finding indicates that all commodity and Islamic stock indices serve as a diversifier in general. However, MSCI Bahrain, MSCI Kuwait, and precious metals act as a safe-haven asset during certain periods of the GFC and Covid-19 crises. Interestingly, KLFTEMSI and JKII present the highest hedging effectiveness over the study period.

Authors:   , Kongsen Stapana 
Published: September 2023

The frequency of high energy storm and tsunami events is crucial for apprehending the vulnerability of coastal communities. Identifying and dating sedimentary evidence deposited by such high energy events can assist in the planning and installation of suitable protection measurements. The Andaman Sea coast of Thailand is particularly vulnerable to such events as illustrated by the 2004 Indian Ocean Tsunami (2004 IOT) and the South China Sea coast of Vietnam has been experienced from the past severe storm event. Here, the authors study the high energy sediments. The selected area of Andaman Sea coast Thailand is Laem Son National park, while the South China Sea coast of Vietnam is located in Hoa Duan, Thua Thein Hue.

The results indicate that in Laem Son area, two high energy sediment layers are discovered including the 2004 IOT layer and a storm layer. The depositional age of the storm event occurred more than 350 years ago. For Hoa Duan coastal area, six layers of high energy events belonged to storm and fluvial flood layers were discovered. Two layers of storm event and one layer of fluvial flood event occured during 130±10 years ago and two layers of storm event and one layer of fluvial flood event occurred more than 130±10 years ago.
Trace elements and color-causing role in spinel and tanzanite
Authors:   , Pluthametwisute Teerarat 
Published: September 2023

This research is aimed to investigate the significant trace elements and their color-causing roles in tanzanite and spinels (7 color varieties) by focusing on their concentrations, valencies, and site occupancy since no palpable research has been reported previously either before or after heating of both gems. According to this finding, natural tanzanites usually show strongly trichroic colors of violet, blue, and brown in different directions. However, this characteristic is easily changed to violet-blue dichroism after heat treatment. As the result, the violet-blue absorption band (centered around 450–460 nm) is obviously decreased after heating, and XAS analysis indicates the higher valency state of vanadium. Consequently, vanadium is strongly suggested as the significant coloring agent in tanzanite which is also supported by its dominant concentration.

Based on this finding, natural spinels contain trace elements which may cause various hues. Red color is attributed by the combination of significant Cr and V ratios. Magenta and purple to blue and green colors are affected by significant Fe content, whereas orange color shows contribution to significant V content. After heating, XAS indicates a greater oxidation state as well as disordering of iron and vanadium, while Cr stays consistent. Broadening of the dominant peak at around 406.2 cm-1 and the occurrence of additional small peak at around 715.2-719.8 cm-1 in Raman spectra as well as broadening of the 685 nm and poorly defined structure of additional peaks in photoluminescence spectra are significant indicators of inverse spinels (heated spinel) which strongly benefits gem-testing laboratory to recognize the heat-treated spinel.
Cost-effectiveness analysis of managed care for osteoporotic hip fractures
Authors:   , Kotnarin Benchaporn 
Published: September 2023

Osteoporotic fracture patients are still unidentified, untreated for osteoporosis. This group of patients is likely to have recurrent fractures and has more morbidity, these problems put a burden on the high cost of taking care of patients and poor clinical outcomes. The intervention for improving the quality of osteoporosis treatment, King Chulalongkorn Memorial Hospital (KCMH) calls “Managed care”. Managed care has an orthopedist who plays a crucial role in fragility fracture and long-term osteoporosis treatment. The purpose of this study is to access the cost-effectiveness of managed care for patients aged 50 years and over with osteoporotic hip fractures compared to “Conventional care” which focuses on only perioperative management does not provide secondary fracture prevention.

The economic evaluation is used a Markov decision-analytic model to estimate the incremental cost and effectiveness of each group and used provider perspective. Conventional care is recruited from 2012 to 2013 (N=110), managed care is recruited from 2017 to 2019 (N=82). At a one-year follow-up, the study found that the death rate is decreasing from 11.8% in conventional care to 3.7% in managed care (P=0.045). The rate of the initiated osteoporosis drug, rate of BMD test, adherence, and the number of OPD visits are significant increases in managed care when compared to conventional care (P<0.001). For base-case analysis, the average cost of conventional care is 419,353 baht and yielded the average life-year gained at 8.2 life-year gained. In addition, the average cost of managed care is 263,474 baht and yielded the average life-year gained at 12.3 life-year gained. From the result of the incremental cost, the managed care is cost-saving at 38,019 baht for one additional life-year gained. In conclusion, managed care is post-fracture recurrent prevention which can be closed the osteoporosis treatment gap and decrease fracture complications after sustained osteoporotic hip fracture and is suggested to be cost-saving.
Hamiltonian decompositions of hypergraphs
Authors:   , Saengchampa Chutima 
Published: September 2023

In this dissertation, we first discuss four versions of Hamiltonicity in hypergraphs. We mainly study the existence problem of Hamiltonian decompositions of uniform hypergraphs based on two versions of Hamiltonian cycles, so called ``KK-definition" and ``WJ-definition". For KK-definition, we create a recursive construction of KK-Hamiltonian decomposition of complete 3-uniform hypergraphs.
Our construction method uses a KK-Hamiltonian decomposition of the complete 3-uniform hypergraph, Kt(3), and some well-known graph decompositions to obtain a KK-Hamiltonian decomposition of the complete t-partite 3-uniform hypergraph, Kt(n)(3), when t=4,8 (mod12), n>=2, as well as a KK-Hamiltonian decomposition of K2t(3). Therefore, together with the current results in literatures, our method provides
a KK-Hamiltonian decomposition of the complete 3-uniform hypergraph, Kt(3), and the complete t-partite 3-uniform hypergraph, Kt(n)(3), when t=2m, 5*2m, 7*2m, 11*2m and m>=2, and n>=2. Furthermore, we establish a WJ-Hamiltonian decomposition of the complete 4-uniform bipartite hypergraph, Kn,n(4), where n=1(mod 4) and n is a prime number.
Integer-valued polynomials over discrete valuation domains
Authors:   , Meesa Rattiya 
Published: September 2023

The classical theorem of Lucas states that binomial polynomials, which form a basis for integer-valud polynomials, satisfy a congruence relation, modulo a prime, related to their digits in the base prime representation. In this thesis, we define the Lucas property in the setting of discrete-valued structures and investigate when and where the Lucas property holds. General criteria are derived for bases of integervalued polynomials in this setting to satisfy the Lucas property. Examples of bases including those of Lagrange type and of Carlitz-like polynomials are worked out. In addition, one of the best known properties of binomial polynomials in the classical case is the Pascal triangle equality, which equates the sum of two binomial coefficients to the one in the following line. In the second part of the thesis, we define a general Pascal property and prove a characterization for polynomials which satisfy this Pascal property. Examples of bases of integer-valued polynomials satisfying such a Pascal property, which embrace the classical case, are derived.
Association between gene expression and promoter methylation of CGB3, GSTP1 and NOP56 genes and their potential in biomarker development - associated cervical cancer.
Authors:   , Singh Palak 
Published: September 2023

Binding of DNMT1-E7 complex can induce promoter methylation in tumor suppressor genes, such as CCNA1, CADM1 leading to their expression suppression and thus, cause cancer progression. This research establishes the association between methylation-related expression of CGB3 and NOP56 genes in cervical cell lines treated with 5-Azacytidine drug. Using MSP-PCR and qPCR, it was found that the methylation of CGB3 and NOP56 were significantly decreased as concentration of 5-Aza increased and this was inversely related with their expression. This demonstrated the association between gene methylation and the regulation of gene expression which were assessed by 5’-aza drug treatment. Of note, the identification of malignancy in screening PAP samples (included ASC-US) based on cytology and histology, were determined by evaluating the performance of methylation status of CGB3 and NOP56 genes using MSP-PCR. Based on statistical results using Python programming, CGB3 gene showed high sensitivity and specificity compared to NOP56 with significant diagnostic ability to distinguish between the “Normal” and “Abnormal” samples. This indicates that CGB3 has more potential to distinguish and identify the malignancy in cervical screening PAP samples at their early stage.
Effects of curcumin and B1-6-12 on alterations in cell viability, oxidative stress, expression of tight junction proteins and barrier property of endothelial cell and pericyte induced by cisplatin and oxaliplatin in vitro
Authors:   , Tothonglor Amornrat 
Published: September 2023

Cisplatin and oxaliplatin are platinum chemotherapeutic drugs that can cause peripheral neuropathy. Nowadays, the pathogenesis of cisplatin/oxaliplatin-induced neuropathy has not been completely elucidated. Emerging evidence revealed that both drugs cause vascular complications. Both drugs might damage nerve capillaries leading to cisplatin/oxaliplatin-induced neuropathy. The objective of this study is to examine the effect of curcumin and B1-6-12 on cisplatin and oxaliplatin-induced alterations in cell viability, apoptosis (caspase-3), oxidative stress (ROS and GSH/GSSG ratio), expression of tight junction proteins (claudin-5, occludin, ZO-1, and ZO-2), and barrier property in endothelial cell and pericyte in vitro. Human umbilical vein endothelial cell (HUVEC) and human brain vascular pericyte (HBVP) were utilized as a model of endothelial cells and pericytes, respectively. Cisplatin caused the reduction of cell viability, induction of caspase-3, overproduction of oxidative stress, depletion of tight junction protein expression, and barrier dysfunction in both HUVEC and HBVP. Co-treatment with curcumin improved these toxic effects in both cells. Moreover, co-treatment with B1-6-12 improved all damage except oxidative stress in both HUVEC and HBVP. Oxaliplatin also caused alterations in HUVEC and HBVP similar to cisplatin and curcumin relieved the alterations in both cell types. In contrast, B1-6-12 was not effective against oxaliplatin-induced cytotoxicity in both HUVEC and HBVP. The combination of curcumin and B1-6-12 was not significantly more effective than curcumin or B1-6-12 alone in most parameters. Both curcumin and B1-6-12 are effective against cisplatin-induced endothelial cell and pericyte cytotoxicity: however, only curcumin is the potential treatment against oxaliplatin-induced microvascular damage. In addition, it is not worth combining these two agents for the management of platinum chemotherapy-induced microvascular toxicity.
Precise extratemporal pattern and intramuscular distribution of the facial nerve
Authors:   , Uruwan Sukanya 
Published: September 2023

An arborization of the branches of the facial nerve has the most complexity and variability. Moreover, knowledge of the facial nerve has great importance for surgical and non-surgical interventions in the face region. However, few studies have attempted to determine the entire course and pattern of terminal branching of the facial nerve in the extratemporal and intramuscular parts of the face. Therefore, the purpose of this study was to investigate the precise detail of the facial nerve in extratemporal and intramuscular parts. This study was conducted in forty-two hemifaces of embalmed cadavers by conventional dissection, fourteen hemi-faces of embalmed cadavers by histological study, and sixteen hemi-faces of soft cadavers by Sihler’s staining technique to investigate the characteristics of the branches of the facial nerve. The results revealed that the mean number of the temporal, zygomatic, buccal, marginal mandibular, and cervical branches of the facial nerve were 2.57 ±0.83, 1.83 ±0.69, 3.10 ±0.82, 1.36 ±0.49, and 1.07 ±0.26 branches respectively. The branches of the facial nerve were distributed deep to the parotido-masseteric fascia, temporo-parietal fascia, superficial musculo-aponeurotic system, and platysma muscle depending on each branch of the facial nerve. In conclusion, a caution area of each branch of the facial nerve should be carefully performed based on intensive nerve distribution to prevent complications and unexpected outcomes.
