Opis:
Southern Thailand, located on the thick and stable Sibumasu continental block, is known for its high heat flow despite lacking volcanic activity (Sautter et al., 2017). This study employs the Curie Point Depth (CPD) calculation, an indirect method, to evaluate land heat flow (e.g., Hsieh et al., 2014; Li et al., 2017; Qudsi, 2019). By analyzing airborne magnetic data and utilizing spectral analysis, the study generates CPD, thermal gradient, and heat flow maps for southern Thailand (e.g., Carrillo-de la Cruz et al., 2020; Núñez Demarco et al., 2021). The findings reveal heat flow values ranging from 61.54 mW/m² to 154.25 mW/m², with an average of 90.36 mW/m², surpassing the typical heat flow of 65 mW/m² for continental crust (Turcotte & Schubert, 2002). The study identifies five distinct zones characterized by higher heat flow compared to the surrounding areas: the Ranong fault zone (RF), Khlong Marui fault zone (KMF), coastline of Surat Thani and Nakhon Si Thammarat, Trang and Satun zone, and the Bentong-Roab suture (BRS). The RF and KMF represent active strike-slip faults that penetrate the continental crust into the upper mantle (Kanjanapayont et al., 2012; Sautter et al., 2017), while the BRS denotes a weak zone marking the suture between Sibumasu and Indochina terranes (Metcalfe, 2000), potentially extending into the mantle. The elevated heat flow observed along the coastline of Surat Thani and Nakhon Si Thammarat, as well as in the Trang and Satun zone, may be influenced by burial faults or fractures. Interpretation with P-wave tomography suggests a possible high heat mantle anomaly under southern Thailand (Huang et al., 2015). These initial findings suggest that the high heat flow in the thick and stable continental crust of Sibumasu originates from mantle upwelling caused by surrounding subducted plates under Eurasia. These heat sources manifest through weak zones in extensional regimes such as the RF, KMF, and possible undefined burial faults or fractures, as well as the BRS. The study provides preliminary understanding of present-day geodynamics of the Sibumasu block and its potential implications for mineral resources, petroleum exploration, geothermal energy, and carbon capture and storage.

geotectonics
Thailand
Opis:
The geotectonic divisions, which are distributed as narrow zones in the north-south direction, are clear in the northern Thailand, but not clearly recognized in the Central Thailand. The Chao Phraya Plain, which occupies the central part of Thailand, is broadly covered with Quaternary sediments. Therefore, the basement rocks of the Paleozoic and Mesozoic are scattered in the form of residual mounds, and due to the lack of stratigraphic and age-determination data, the geological origin of these rocks have been not sufficiently discussed. In this presentation, we will report the results of a study on the geological belongings of bedded chert sporadically exposed in the Chao Phraya Plain, Central Thailand by the microfossil age and geochemical characteristics. The study areas are Thung Saliam (TS) (50 km northwest of Sukhothai) in the northern part of the plain and the Nakorn Sawan–Uthai Thani (NS-UT) area in the central part of the plain. About 20 outcrops of chert were surveyed in both areas. The cherts are distributed in scattered, and most of the cherts are recrystallized and are considered to have undergone contact metamorphism. Chert of the TS is well-bedded with red and the direct contact relationship is unknown, but tuff and limestone (marble) are exposed around it. Chert of the NSUT is also well-bedded with red, black, gray and milky white in color. Altered slatey shale and sandstone accompany the chert and form monadnocks. These cherts might be categorized into typical pelagic cherts because they contain radiolarian tests and sponge spicules in a matrix consisting of very fine clay minerals and microcrystalline quartz, and do not contain coarse-grained terrigenous materials. Sashida & Nakornsuri (1999) reported the occurrence of Pseudoalbaillella simplex, Ruzencevispongus sp., and so on from the TS chert and they assigned their age to Wolfcampian. Whereas, Saesaengseerung et al. (2007) report radiolarian occurrence of the Ps. loemntaria Assemblage (Artinskian) and Follicucullus scholasticus Assemblage (Capitanian-Wuchiapingian) from the NS-UT chert. Whole-rock chemical analysis was performed on three sections their ages were determined by radiolarians. In the Chondrite-normalized REE pattern, TS chert indicates negative anomaly of Ce, and NS-UT chert shows relatively flat and profile of the downward-sloping in the LREE. The geological age of the study sections and their REE patterns are similar to those observed in the Sa Kaeo area in southeastern Thailand. The Permian bedded cherts exposed in TS and NS-UT areas are often accompanied by thin layers of fine-grained siliciclastics and tuff, which are weakly metamorphosed and foliated. Since the chert itself has a relatively thin thickness (several meters to 10–20 m) in each outcrop, and basically has a north-south strike. These cherts occurrence and lithofacies of both areas are similar and indicate that cherts of both areas are geologically comparable as pointed out by Ueno et al. (2012). Ueno et al. (2012) clarified that the central part of Thailand, where the geotectonic division was unclear, can be divided into three geotectonic units from west to east: Sibumasu Block, Sukothai Zone and Indochin Block. However, the origin of the Permian chert has not been clarified. Paleozoic and Mesozoic cherts distributed in Thailand remind us bedded cherts deposited in the Paleo-Tethys from the Devonian to the Triassic. However, no cherts other than the Permian have been reported in the central part of mainland Thailand. Instead of the Paleo-Tethys chert, the Sa Kaeo-Chanthaburi suture and the Nan-Uttaradit suture are well-known as geological units containing Permian chert in southeastern Thailand. These sutures have been understood as a closed remnant of the Permian to Triassic back-arc basin stretched between the Indochina Block and the Sukhothai Arc. The fact that the Permian cherts of the central plain are distributed in the eastern part of the Sukhothai Zone and near Indochina Block suggests that these Permian cherts comparable to the Permian chert of the Sa Kaeo-Chanthaburi Suture. In addition to the geological evidence, the geochemical features of the Permian chert represented by the REE pattern are similar to those of the Permian chert in the Sa Keo area. Line of evidence mentioned above suggests that the Permian bedded chert distributed the central Thailand (TS and NS-UT areas) have originated to the Permian chert of the Sa Kae-Chanthaburi or Nan-Uttaradit sutures which is a remnant of backarc basin.

Opis:
Along the Northern part of the West Thailand Region (NWTR), a long-lasting belt of radiolarian cherts, separates Pennsylvanian to Permian palaeotropical limestones of the Inthanon Zone to the east from Permian limestones in the west containing a temperate marine fauna in the Roadian and a biogeographically distinctive fusulinid fauna in the Wordian. Highly abundant but low diversity of Kungurian radiolarians in silicified shales as well as temperate faunas in limestones from the south and the west of Thailand, respectively support constrains in the temperate environment during the period of deglaciation in peri-Gondawana. The well-known underlying diamictite and overlying temperate sediments with the succeeding fully tropical limestone sequences support a gradational palaeoclimate transition. Devonian faunas found in condensed sequences of the NWTR were deposited in a deep platform or ramp environment. A lack of basalts in the NWTR does not suggest oceanic environments for any Palaeozoic sequence within the NWTR and a paucity of basalts in the northwestern part of the Inthanon Zone also does not provide good evidence of an oceanic realm. Indeed, ‘continental margin’ Carboniferous sandstones appear to underlie the palaeotropical limestones and their plant fossils and their benthonic faunas do not suggest oceanic conditions in the northwestern Inthanon Zone. We, therefore, suggest that an autochthonous or para-autochthonous Inthanon Zone origin for these Carboniferous sandstones is more likely than deposition within a subducting Palaeotethyan Ocean. A strong contrast between the ‘temperate’ Permian limestones of the NWTR and the tropical limestones of the Inthanon Zone further emphasises the Mae Yuam/Mae Sariang Fault Zone (MYMS FZ) as a reactivated oceanic boundary between Gondwana and ‘Cathaysia’ and is supported by the oceanic lithosphere origin of the detrital Cr spinels in the Triassic foreland basin siliciclastics of the NWTR. The limestones of the Inthanon Zone range from Visean to Permian and possibly Triassic and were deposited in shallow, tropical seas for over 90 million years. This longevity is either not possible or highly unlikely for shallow marine carbonates on volcanic seamounts supported on subducting (and therefore cooling and sinking) ocean crust (Huppert et al., 2020) but is possible on isolated carbonate platforms on continental crust separated by narrow basins with limited volcanism. Carboniferous sandstones and Devonian-Permian radiolarian cherts from the Inthanon Zone are continental marginal and are neither pelagic nor oceanic and are interpreted as deposited in extensional, deeper basins between the isolated carbonate platforms. We suggest an alternative hypothesis to the overthrust/ allochthon model where the NWTR is the eastern platform margin of the Sibumasu Terrane from the Devonian through to the Triassic and separated from the Inthanon Terrane by an ocean in the position of the MYMS FZ. It is suggested that Inthanon rifted from Gondwana in the Early Devonian and the NWTR, as part of the Sibumasu Terrane, rifted off in the early Permian. As the Inthanon Terrane ribbon continent drifted northwards the continental crust thinned and extended and small rift basins allowed basalts to be extruded associated with deep-water, continental margin, hemipelagic, non-hydrothermal radiolarian oozes. Isolated carbonate platforms were established on Carboniferous sandstone bases and were separated by deep-water but non-pelagic extensional basins. Turbidites originating on the carbonate highs supplied carbonates clasts containing Devonian through Permian conodonts, to the adjacent basins (Udchachon et al., 2018). We provisionally suggest that the Sukhothai Terrane rifted with Inthanon with its older siliciclastic successions of the Siluro-Devonian (?) Khao Kieo Formation and the unconformably overlying Carboniferous (Dan Lan Hoi Group) (Bunopas, 1982; Ueno & Charoentitirat, 2011) supplying siliciclastic and volcaniclastic debris to the Inthanon Zone. This hypothesis is broadly in accord with Dew et al.’s (2018) ‘explanation A’ for the crustal geochemistry of the northern Thailand terranes. In the early Permian (Kungurian) Sibumasu was probably in cool to temperate seas but by the middle Permian, the NWTR had rifted from Gondwana and was in the southern hemisphere tropics (13° ±2° S, Zhao et al., 2020). Terrane collision occurred during the Triassic (Ishida et al., 2006; Mitchell et al., 2012; Cai et al., 2017; Hara et al., 2021) with the establishment of a thrust front along the Mae Sariang Thrust Zone and the deposition of the mainly siliciclastic Mae Sariang Group on the NWTR within a foreland basin.

Opis:
Permian chert and siliceous mudstone in the Soi Dao, Chanthaburi Thailand are extracted the details on radiolarian assemblage and age, change of depositional environment, and geochemical characteristics. Permian radiolarians were obtained in three study areas (ASD01, ASD14 and ASD09); which radiolarian age of each section is as follows: ASD01: Early Asselian to Early Sakmarian, ASD14: Late Sakmarian to Artinskian, and ASD09: Capitanian to Early Changhsingian. Considering the lithofacies, ages, and chemical composition of the rocks, a preliminary stratigraphy consisting of basaltic rock, radiolarian bedded chert, siliceous mudstone, and coarse-grained clastic of alternation of sandstone and mudstone in ascending order can be reconstructed. Data on geochemistry analysis, particularly chondrite-normalized REEs patterns of chert and siliceous mudstone, present a gradual change in that degree of the Ce negative anomaly decrease toward the stratigraphical upper position. These changes indicate that the depositional site of the Permian rocks transferred from a state of high hydrothermal activity to a state of weakened activity and that the influx of terrestrial clastics increased. Permian bedded cherts accompanied by basalts and siliceous mudstones recognized in the study area closely resemble to the Paleo- ‑Tethys bedded cherts in terms of their lithofacies and microscopic features; however, their depositional period is much shorter than that of the Paleo-Tethys, indicating that it was deposited in another oceanic basin. The chemical compositions also show that the influence of hydrothermal activity weakened from the strong state, and the terrigenous clastics rapidly supplied.

Khao Khwang Formation is widely distributed in central Thailand. It is represented by Late Pennsylvanian to Middle Permian thick-bedded limestone with chert nodules. Rock samples belonging to this formation have been collected. They are light to dark grey, thick-bedded to massive limestone with black nodular cherts. The abundant and extraordinarily gigantic bivalve Alatoconchidae together with fusulinoidean fauna (Verbeekina verbeeki, Colania douvillei and Pseudodoliolina pseudolepida), fragments of coral, ammonoid, brachiopod, sponge, gastropod, etc. were observed. Based on the characteristic fusulinoidean fauna, it indicates Capitanian in age. Microscopically, limestone samples were classified as bioclastic rudstone and packstone. The detailed lithologic and carbonate microfacies observations, Alatoconchidae beds, deposited parallel to the bedding plane and related with oncoids and microbial, are autochthonous in shallow marine. Condensed accumulation of other fossil fragments found in the study areas might be transported by gravity flow.

When we think of Thai bridges we think above all of the bridge on the Kwai river. We tend to ignore the bridges across the Chao Phraya river in Bangkok, which we think of as mere places of transit between airplane to bus. Yet these bridges are so interesting and varied that it is worth stopping even for a couple of days to observe them from the water tram and from shore.

Because of the COVID-19 situation, selection for a teaching assistant position to get a TA scholarship in a university in Thailand needs to be performed online by the formed committee. Due to the online process and the limited number of scholarships offered by the university, beyond the face-to-face interview, multiple-criteria decision analysis can help to select a proper student. In this study, we use the extended VIKOR method with fuzzy numbers to help committees to select the students from the applicants. The criteria and the weights of the criteria are provided with the help of committees. Both trapezoidal and triangular linguistic variables are used to find the solution and to observe the range of the possible result. The different weights supporting the strategy of maximum group utility are varied to detect the potential alternatives. The ranking results are also compared with the one obtained from the TODIM approach to illustrate the appropriate alternative.

Objective. This study examined associations between socio-demographic characteristics and knowledge, attitudes, and practices (KAP) related to COVID-19 among healthcare workers in Bangkok, Thailand. Materials and methods. A cross-sectional online survey was distributed among healthcare workers in Bangkok, Thailand from July - August 2021. Results. A total of 637 responses were received. Most participants were clinical workers (68.4%), and nearly half (47.3%) had been at risk of infection with COVID-19 (ever screening test). Binary logistic regression analysis found associations between high knowledge scores and the 26–35-year age group (OR=1.776-1.562, 95%CI 1.021–2.853), having a bachelor’s degree or higher (OR=1.672, 95%CI 1.058–2.644), and clinical workers (OR=1.784, 95CI% 1.188–2.678). The 36 year and above age group was associated with higher attitude scores (OR=2.406, 95%CI 1.567–3.695). Higher practice scores were associated with females (OR=1.913, 95%CI 1.057–3.464), and clinical workers (OR=1.903, 95CI% 1.170–3.095). Correlation analysis found a positive correlation between practice scores and knowledge (r=0.322, p <0.001) and attitudes (r=0.263, p <0.001). Conclusion. Although healthcare workers demonstrated overall high knowledge, attitude, and practice scores, this study identified several factors that influence KAP. This study can guide public health strategies regarding healthcare workers during the third wave of the COVID-19 pandemic in Thailand.

Opis:
Escherichia coli producing extended-spectrum beta-lactamase (ESBL) are antimicrobial-resistant Enterobacteriaceae important in the livestock production sector, especially dairy cows because these antimicrobial-resistant bacteria can be transferred to consumers via consumption. If antimicrobials are continually used in dairy farms, this may result in antimicrobial resistance. Therefore, investigation of antimicrobial resistance and finding new alternative methods for inhibiting ESBL-producing E. coli is essential. Hence, the aim of this study was to examine the ability of selected antimicrobials to inhibit E. coli ATCC 25922, control bacteria and ESBL-producing E. coli isolated from dairy farms. We also investigated the capacity of polyphenol extract from 10 varieties of medicinal plants to inhibit ESBL-producing E. coli using a broth microdilution method. It was found that control bacteria were susceptible to all antimicrobial agents, i.e., ampicillin, cefotaxime, ciprofloxacin, chloramphenicol, gentamycin, imipenem, nalidixic acid, tetracycline, and sulfamethoxazole/ trimethoprim. However, ESBL-producing E. coli exhibited both susceptibility and resistance to selected antimicrobials. The polyphenol extracted from Psidium guajava Linn at the lowest concentration was 4.5 mg/mL, which could inhibit control bacteria, but at the same concentration could not inhibit ESBL-producing E. coli. These phenomena indicated that ESBL-producing E. coli had both susceptibility and resistance to antimicrobials. Polyphenol, which could inhibit non-resistant E. coli, could not inhibit ESBL-producing E. coli.

The Urak Lawoi are indigenous fishermen on Thailand’s west coast. The population includes an estimated 400 divers who dive using surface-supplied compressed air. In a cross-sectional survey conducted among the 6 major communities of Urak Lawoi, questionnaire-based interviews were administered to active divers, ex-divers, and families or colleagues of divers who had died in the previous 5 years. Six deaths resulting from diving-related accidents were identified, indicating a diving-related mortality rate of approximately 300 per 100,000 person-years, while in the same 5-year period 11 divers had been disabled owing to diving-related events, indicating a diving-related disabling event rate of approximately 550 per 100,000 person-years. Among 342 active divers interviewed, one third reported having suffered from decompression illness, although based on reported current symptoms over 50% were classified as suffering from recurring non-disabling decompression illness. Physical examination conducted on a subset of 98 active divers revealed the presence of spinal injury (clonus, raised muscle tone, and heightened reflexes) and of joint damage (pain in one or more joint, crepitus, or restricted movement) in 24 and 30% respectively. Improved primary prevention and medical treatment are needed to reduce mortality and morbidity among this population.

Field observation was used to further develop information and confirm diving practices. Divers in 6 villages, whose basic means of making a living is from diving for marine products such as fish and shellfish, have diving patterns that put them at substantial risk of decompression illness. Breathing air from a primitive compressor through approximately 100 m of air hose, these divers have long bottom times coupled with short surface intervals. Forty-six point two percent of the divers indicated that they would not make a stop during ascent from a long deep dive (40 m for 30 min). When comparing their previous day of diving to the U.S. Navy Standard Air Decompression Table (U.S. Navy, 1993), 72.1% exceeded the no-decompression limits set by the tables. Diving patterns point to a need for more in-depth research into the diving patterns of this indigenous group. Future research should include the use of dive logging devices to record depths and times. There is also a need to provide divers with information and training to reinforce positive practices and strengthen knowledge of the risks associated with their current diving practices.

Opis:
Thailand hosts over 50 percent of the world’s top OEM automotive parts suppliers and additionally is home to over 2,400 Tier 1-3 manufacturers and suppliers. Given the significance of these numbers and Thailand’s leading ranking and contribution to the global automotive industry, research was undertaken to determine how manufacturing clusters and innovation capability effect competitive advantage as it relates to automotive production part management. Multiple objectives were established which included the study of the effects and overall influences of the various variables on competitive advantage as well as the development of a structural equation model (SEM) to define how innovation and manufacturing clustering affects the competitive advantage within the Thai automotive parts molding sector. Quantitative methods analysis was conducted on the data from 240 automotive production and components suppliers’ questionnaires collected from industry managers with the research results partially obtained from the analysis by use of (PLS)-graph. Qualitative research was also obtained by use of purposive sampling from in-depth interviews from ten senior managers. The results obtained indicated that clusters and innovation capability has a significant and positive effect on competitive advantage. Thus, the findings from the research illustrate that if an organization focuses on clusters, there will be a knock-on effect within the automotive parts groups leading to the increase in innovation capability, which creates a greater competitive advantage, not only for the enterprises, but also for Thai society as well.
