title: The impact of language assessment literacy training on EFL university lecturers’ language assessment literacy, efficacy and practice of student self-assessment

description: The literature suggested that limited assessment literacy in the use of SSA has led to insufficient use of SSA in Thai tertiary EFL classrooms. This study examined the current assessment practice, assessment literacy, and assessment efficacy in the use of SSA of the EFL lecturers who were serving at the nine Rajamangala Universities (RMUTs) and the effect of assessment literacy training on the assessment literacy, assessment efficacy, and assessment practice in the use of SSA among four EFL lecturers from one particular Rajamangala University. In this study, the researcher utilised mixed-methods research, a paradigm in which she drew on data from the questionnaire survey of 163 respondents, augmented with the data from a semi-structured interview with 48 interview informants. It was found that the lecturers at the nine RMUTs had moderate levels of assessment literacy and assessment efficacy in the use of SSA. Identification of emergent themes in the training participants’ responses provided crucial information relevant to the continuous, job-embedded assessment literacy training in the use of SSA, from which the lecturers improved and increased their levels of assessment literacy and assessment efficacy while applying assessment practice in the use of SSA in their classrooms. The training was found to be meaningful to the lecturers at the nine RMUTs, particularly with regard to the following aspects: the opportunity to share goals regarding assessment practice in the use of SSA, the provision of resources and support, implementation and hands-on experience of SSA in classrooms, and collaboration in a learning community.

title: The use of a cooperative corpus consultation to promote the acquisition of adjective + preposition collocations among L1 Thai learners of English

description: The study was aimed at promoting the acquisition of adjective + preposition collocations of L1 Thai learners of English through a cooperative corpus consultation. The three objectives were to investigate the effects of a cooperative corpus consultation, explore learners’ strategies in dealing with the corpus consultation and study learners’ attitudes towards the approach. The study was conducted for one semester with 74 first year university students at Srinakharinwirot University. One group was assigned to be the experimental group working on the paper-based concordance handouts and hands-on concordance based tasks with a group of 3 - 4 members while the other represented the comparison group working on the same tasks individually. The research instruments included a pre-test and a post-test, a pre-project questionnaire, reflective journals, classroom observation schemes, a post-project questionnaire, a “can-do statement questionnaire and stimulated recall interviews. The findings can be summarized into three areas. Firstly, the average scores of the two groups were significantly different. Secondly, the results revealed different use of strategies. The experimental group employed group discussion, technological tools and positive interdependence while the control group relied on seeking help from the instructors and their peers and the use of their L1. Lastly, although both groups showed their positive attitudes, the control group reported problems and confusion which might have effects on future use of corpus consultation.

title: A study of criteria for air cargo terminal classification model

description: Global air cargo transportation has performed a significant role to the trade industry over the past decades for goods delivery. Airlines transport approximately 51.3 million metric tons of goods, or more than one third of worldwide trade or USD 6.8 trillion by value annually. Air cargo terminal is a key success of airlines in the supply chain network at airports. This study is aimed to explore and analyze important criteria of air cargo terminals on the integration of 63 criteria from previous researches of practical operations and International Air Transport Association regulated standard services. To examine reviewed criteria, this paper investigates the criteria significance by 57 of 75 air cargo terminal operators around the world except in Thailand covering 474 air cargo terminals in 6 continents. Also, this research cooperatively evaluates the criteria and employs Factor Analysis by using Principal Component Analysis program for criteria reduction with the similarity. The result of final validation from aviation experts, academicians, government bodies, air cargo logistics service providers and airlines in air cargo related industries reveal that 9 integrated criteria with 44 sub-criteria and factors loading scores are remained important. The significant criteria are studied with air cargo terminal operators in Suvarnabhumi, Chiang Mai, Don Muang and Phuket international airports as a sampling to testify the criteria and model from the first phase finding. There are 5 of 7 operators who participate this assessment only in Suvarnabhumi, Chiang Mai and Phuket international airports. Raw data is given and input in Hierarchical Cluster Analysis program to cluster all 5 air cargo terminal operators into 2, 3 and 4 classifications homogenously. Thai Airways as an air cargo terminal operator in Suvarnabhumi international airport is clustered separately in one classification and obviously outstanding from the other 4 air cargo terminal operators and all classification are presented. Still, strength and weakness of Thai Airways in each criteria and all 9 main criteria are analyzed as results from second phase finding of this research and compared with the best practice of air cargo airport namely Hong Kong international airport. Also, this is proven that the significant criteria are workable and practical for air cargo terminal classification model as a new body of knowledge for third phase finding. Later, the 9 main criteria with 44 sub-criteria and factor loading scores are constructed into the guideline and check list that are available for academicians, air cargo terminal operators, government bodies and interested stake holders around the world to prepare and apply to their business and academic purposes.

title: Involvement of Notch signaling in interleukin-4-stimulated human macrophages

description: Macrophages respond to various stimuli, resulting in distinct effector phenotypes that range from LPS-stimulated proinflammatory to IL-4-activated pro-healing phenotype. The regulatory mechanism of this polarization is not fully understood. Notch signaling pathway is a conserved signaling pathway involved in polarization of macrophages, especially proinflammatory macrophages. However, the role of Notch signaling in IL-4 stimulated macrophages (M(IL-4)) is not well defined. PPARgamma is a signature nuclear receptor in M(IL-4) that function mainly in regulating lipid metabolism. There are many reports that revealed the interaction of Notch signaling and PPARgamma in various cells but not in macrophages. In this study, the interaction between Notch signaling and PPARgamma in M(IL-4) using THP-1 cell line and primary human monocytes derived macrophages was investigated. M(IL-4) activated Notch signaling that required the activity of g-secretase to cleave Notch1 receptor. Notch1 intracellular domain (NIC1) overexpressing THP-1 increased PPARgamma expression in the presence or absence of IL-4. Furthermore, g-secretase inhibitor pretreated M(IL-4) decreased PPARgamma level. In contrast, overexpression of dominant negative mastermind-like (DNMAML), a dominant negative for Notch signaling, in M(IL-4) had no effect on PPARgamma level. NIC1 overexpression increased PPARgamma stability by delayed proteasome degradation but not the mRNA transcription or stability. RNAseq was performed to obtain global insight of Notch signaling in M(IL-4). NIC1 overexpressing M(IL-4) showed enrichment of proinflammatory gene sets consistent with previous reports. More importantly, some gene sets of pro-healing macrophages were enriched as well. Network analysis revealed the links between Notch and PPARgamma through NEDD4L, an E3 ubiquitin ligase and SGK1, which has 45-55% of catalytic domain similar to AKT. Deletion of NEDD4L in the presence of NIC1 overexpression in M(IL-4) reduced PPARG mRNA expression. This reduction of PPARG mRNA was accompanied by decreasing AKT phosphorylation. These results indicated that Notch signaling required NEDD4L for optimal expression of PPARG mRNA. Activation of Notch signaling increased lipid metabolism in M(IL-4) by increasing lipid accumulation via CD36 uptake mechanism. Collectively, this study provides evidences linking Notch signaling and PPARgamma via protein stabilization and NEDD4L mediated PPARG regulation and its effect on lipid uptake. The results obtained in this study indicated that Notch signaling operates in both proinflammatory and pro-healing macrophages.

title: Assessment of Cadmium Migration into Groundwater in Mae Sot District, Tak Province using Monte Carlo Technique

description: Mae Sot is a district in Tak province that confronts Cd contamination within the area. The target organs for Cd exposure was kidneys and skeletal system which could lead to severe health effects such as renal dysfunction, osteoporosis, bone softening, Itai-Itai disease, and lung cancer. The intention of this study was to examine the sorption behavior of nine soil samples in the study area and applied Monte Carlo technique that would increase model efficiency for Cd migration in to the soil profile. Batch adsorption experiments were performed and fitted with the adsorption isotherms as follows: Linear, Langmuir, and Freundlich isotherms. Moreover, BCR sequential extraction was used to extract bioavailable Cd (BCR1+ BCR2), which used as model initial Cd concentration and Cd concentration in soil profile. HYDRUS-1D was used as a numerical modeling instrument to simulate Cd transportation in the soil profile, and MATLAB was used for Monte Carlo application in HYDRUS-1D. Furthermore, Nash and Sutcliffe model efficiency (NSE) was used to evaluated the numerical model in this study. Batch adsorption experiment showed that seven soil samples were fitted well with Freundlich adsorption isotherm (R2 between 0.957-0.984), while the other two soil samples (S1 and S2) were explained by Langmuir isotherm (R2 between 0.995-0.998). However, BCR sequential extraction from soil samples showed that only 2 soil samples (S4 and S5) can be detected Cd concentration in BCR1 and BCR2 Based on the application of Monte Carlo method in HYDRUS-1D (under the non-equilibrium condition), the result showed that the simulation results are lower than the experimental data with NSE values of 0.223 and -1.606 for S4 and S5, respectively.

title: The socio-economic impact of IUU-fishing and its countermeasures on small scale fishermen in Thailand : a case study of Baan Khan Kradai, Ao Noi, Prachuap Kiri Khan

description: This study investigates the socio-economic effects of Illegal, Unreported and Unregulated fishing (IUU-fishing) on households of small scale fishermen, whose income derives almost entirely from fishing. The research question is “What are the socio-economic impacts of IUU-fishing and government’s countermeasures on Thai fishing communities, in particular small scale fishermen’s households, before and after 2015?”. A mixed quantitative and qualitative approach was chosen to better grasp the complexity of fishing-related changes to household income and by the case study of a small scale fishing community in Ao Noi Subdistrict of Prachuap Kiri Khan Province. This resulted to a general understanding of the extent to which the community members were aware of IUU issues, as well as in their participation in related governance processes. The main results show that the small scale fishermen were impacted by those who perform IUU-fishing. Since the enforcement of the new regulation in 2014/2015, the fishermen have felt some improvement through the regrowth of fish stock and the enforcement of stricter regulation for commercial vessels. The income situation has, after initial gains, seen some losses in 2016, mainly due to higher costs or investments. The results shall provide a set of data for future research on the socio-economic situation of small scale fishermen. This approach might be useful as a template to be applied to other small scale fishing communities in Thailand or elsewhere. The limits of this work are clearly given by the sample size and the selected target community.

title: The relationship between geochemical parameters and the communities of arsenite-oxidizing bacteria in Rayong groundwater basin

description: As is one of toxic metalloid commonly found on the earth's surface. In groundwater, arsenite (As3+) and arsenate (As5+) are most predominant As species. Arsenite is more toxic than arsenate. As removal through bioremediation technique can be applied as an alternative method. This study aimed to investigate the community of arsenite-oxidizing bacteria in As-contaminated groundwater and to correlated them to the geochemical parameters. Nineteen groundwater samples were collected from Ban-khai and Muang districts, Rayong province, Thailand. The communities of arsenite-oxidizing bacteria were detected by using PCR-cloning-sequencing techniques, targeting aioA gene. The results showed that the detected arsenite-oxidizing bacteria were associated with α-, β-, and γ-Protebacteria. The γ-Protebacterial cluster was detected in groundwater with low to moderate As concentrations, while it was undetected in groundwater with high As concentration. PHREEQC geochemical model was used to identify the major As species in all groundwater samples. The predominant As species in most groundwater samples is arsenite (As3+) which presented in the form of H3AsO3. In addition, the statistical analysis demonstrated that the geochemical parameters affecting the distribution of arsenite-oxidizing bacteria in this study were Fe, Mn, As3+ and As5+. Fe, Mn, and As3+ showed the positive relationship to the β-Proteobacterial cluster, whereas As5+ positively correlated with α-Proteobacterial cluster. The knowledge gain from this study will help better understand the distribution of arsenite-oxidizing bacteria found in groundwater with a broad range of As concentrations.

title: Assisted Methane Hydrate Formation with the Addition of Promoters

description: Natural gas hydrates play an important role in the largest reservoir of hydrocarbons on earth. The gas hydrates have received increasing attention in an excellent way of new technology for gas in large quantity storage and transportation. However, the main challenge to use methane hy¬drates has faced many challenges such as the slow formation rate, low growth rate during hydrate formation, and low conversion ratio of gas to solid hydrates leading to poor storage capacity. In this work, methane hydrate formation and dissociation in the presence of different Cyclopentane (CP), Tetra-n-butyl phosphonium bromide (TBPB) and Tetra-n-butyl ammonium bromide (TBAB) concentrations were investigated. The formation experiment was conducted in an unstirred system. The temperature was controlled between 2.5 and 4.0°C at 8 MPa. The hydrate dissociation experiment was performed after the completion of hydrate formation. The results showed that the presence of TBPB alone was not sufficient to promote methane hydrate formation. The addition of TBAB to promoted methane hydrate formation with only small amount of methane uptake. Increasing the concentration of CP improved methane consumption. However, the methane consumption in the presence of CP was higher than that with TBAB.

title: Electrical property-investigation of porous clay heterostructures derived from naturally-occurring clay minerals for smart packaging

description: Porous Clay Heterostructure (PCH) is an interesting material to use as entrapping system such as ethylene scavenger, respected to its high surface area with uniform and specific pore size. PCHs have been prepared by the surfactant-directed assembly of mesostructured silica within the two-dimensional galleries of clays. Then, the PCH was synthesized within the galleries of Na-bentonite clay by the polymerization of tetraethoxysilane (TEOS) in the presence of surfactant micelles. In addition, mesoporous clay with organic-inorganic hybrid (HPCH) is modified via co-condensation reaction of TEOS with candidate conductive functional groups (thiol group) and metal loading (silver), designated as MPPCH and Ag-PCH, to enhance surface conductivity of PCH material for using as sensor packaging. Subsequently, all modified PCHs were utilized as ethylene scavenger and blended with polypropylene for producing ethylene scavenging films in food packaging application with various ratios of clay. The morphological, structural, thermal, and mechanical properties were studied and reported in this work. In addition, the modified PCHs and polypropylene/modified PCHs nanocomposite films were also evaluated the potential uses in active packaging and sensor packaging.

title: The Incipient Layer of Wax Deposit

description: The formation of the incipient layer of wax deposit when waxy oil is exposed to a cold surface is studied. Using a cold-finger apparatus, the evolution of deposit thickness is monitored with a video camera, allowing one to resolve the deposit layer formation from inception up to long times where deposit thickness no longer times where deposit thickness no longer grows. Characterization of wax deposits show that incipient layer has identical composition to waxy oil, indicating that deposit is not formed by a diffusion process. Modelling shows deposit formation at the investigated conditions cannot be explained by a diffusion process.

title: Use of Anionic Surfactant in Regeneration of Spent Activated Carbon

description: Surfactant-enhanced carbon regeneration (SECR) is a regeneration process that utilizes surfactant solution to dissolve adsorbed organic from spent activated carbon. Sodium dodecyl sulfate (SDS) and methyl ester sulfonate (MES) are anionic surfactants that are used in this investigation. The study is done in 3 steps: sample characterization, regeneration and water flushing step. The proximate analysis of spent activate carbon contains 27.5% moisture, 27.2% volatile matter content, 10% total ash content. The spent activated carbon also contains 18.4% benzene. In regeneration step, the benzene removal by SDS and MES solution were compared. The effect of concentration, solution flow rate and temperature are studied. As expected, the benzene removal increased as the concentration of SDS or MES increased and the benzene removal by MES is higher than that by SDS at the same concentration. However, SDS was easier to be removed in washing step with deionized water than MES.

title: Detection and distribution of Enterotoxin and Adhesin genes of Staphylococcus Pseudintermedius isolated from dog, human, and environment

description: To obtain the information of virulence factors associated with Staphylococcus pseudintermedius pathogenicity, host survival and adaptation, the study of staphylococcal enterotoxin (SE) genes and cell wall-associated (CWA) protein genes in S. pseudintermedius isolates from dogs, humans, and environment were performed. Human methicillin-resistant Staphylococcus pseudintermedius (MRSP) harbored the hightes number of SE genes at 12 out of 17 genes compared to those from dogs at 5 and environmental isolates at 3 gene types. For CWA protein genes or S. pseudintermedius surface proteins (sps), there was no an easy and fast method to detect them. Therefore, this study develop the multiplex PCR assays (mPCRs) for detection of 18 sps genes. spsP and spsQ were more frequently detected in the canine isolates from infected sites than from carriage sites with statistically significant. The positive amplicons of spsR gene in three human isolates showed partial gene deletions. Adherence assays were performed to assess the ability of 5 MRSP isolates from different origins and to find the relation with CWA protein gene profiles. Three MRSP-ST45 from dog, human, and environment had the greatest ability to adhere to both canine and human corneocytes without the association to sps gene profiles. This study successfully developed the novel mPCR for sps genes detection. The association between sources and enterotoxin genes were hightlighted in the isolates from humans. The diversity of virulence genes in human isolates are assumed to transfer by mobile genetic elements and might associate with higher pathogenicity than dog, and environmental isolates. Moreover, the diversity of sps may be responsible for host adaptation.

title: Difference of some spermatozoa and seminal plasma proteins in good and poor freezability boar ejaculates

description: The present study was performed to determine the differences of some seminal plasma proteins, i.e., glutathione peroxidase 5 (GPX5) and fibronectin 1 (FN1), and some spermatozoa proteins, i.e., triosephosphate isomerase (TPI) and ACRBP (acrosin binding protein), in the boar semen having good and poor freezability. The study was conducted by including 38 ejaculates in seminal plasma study and 32 ejaculates from spermatozoa study from 27 boars (Duroc=13, Landrace= 8, Yorkshire= 6). The semen was split into two portions. The first portion was centrifuged to separate the pellet of sperm from the seminal plasma. The samples were kept at −80 °C until protein extraction. The second portion was cryopreserved. After thawing, the ejaculates were classified into 3 groups according to their post-thawed sperm motility, i.e., good, moderate and poor. Post-thawed sperm motility in each group were 60.2 ± 1.67%, 29.3 ± 2.02% and 16.6 ± 2.17%, respectively. The samples were determined by using Western blot analysis. It was found that the level of FN1 in seminal plasma was higher in the semen with good than poor freezability (0.08±0.01 vs 0.05±0.01, respectively, P &lt; 0.05), but did not differ significantly compared to semen with moderate freezability (0.07±0.01, P&gt;0.05). Additionally, the level of FN1 in the seminal plasma was positively correlated with the post-thawed sperm progressive motility (r = 0.42, P = 0.009), total motility of the boar spermatozoa (r = 0.43, P = 0.007), VAP (r= 0.34, P=0.04), the proportion of bent tail sperm (r = 0.36, P = 0.03) and the proportion of coil tail sperm (r = 0.31, P = 0.05). GPX5 was not correlated with the post-thawed sperm qualities (P &gt; 0.05). However, the levels of GPX5 was positively correlated with FN1 (r = 0.35, P = 0.03). For spermatozoa proteins, the level of TPI was negatively correlated with the post-thawed sperm progressive motility (r = -0.35, P = 0.05) and total motility (r = -0.43, P = 0.01). Additionally, the level of TPI was higher in moderate (4.4 ± 0.46, P &lt; 0.05) than good (3.2 ± 0.36) and poor (4.1 ± 0.39) freezability ejaculates. The level of ACRBP did not differ significantly among semen freezability groups. However, the level of ACRBP was positively correlated with post-thawed total sperm motility (r = 0.38, P = 0.03). It could be concluded that boar semen containing a high level of FN1 in seminal plasma had a higher freezability than those containing low level of FN1. The post-thawed sperm motility were positively correlated with the level of FN1 in boar seminal plasma and the level of ACRBP in spermatozoa and negatively correlated with TPI in boar spermatozoa.
