Four Countries Have Antimicrobial-Stewardship Policies, but 16 Hospitals Average 72% Implementation and Training Lags

This study linked national policy, hospital systems, and provider behaviour in Indonesia, Nepal, Thailand, and Viet Nam during 2022–2023. It included 486 participants across 16 hospitals. All countries had antimicrobial-stewardship policies, but financing, enforcement, training, microbiology-data use, and inter-programme coordination were uneven. Hospitals averaged 72% on G-ASET, with tracking and reporting highest at 75% and training lowest at 66%. The two Thai hospitals scored 81.3% and 80.6% overall, yet both scored only 50% for training. These results identify actionable system gaps; they do not experimentally show that any intervention reduced antibiotic use, resistance, or mortality.

Ergonomic Risks for Ice Production Employees and Assessment of Their Occupational Health and Safety: A Case Study in Surat Thani, Thailand

Musculoskeletal disorders (MSDs) represent a critical global challenge to workforce productivity. In Thailand, these disorders are particularly prevalent in labor-intensive industries such as ice manufacturing, where workers face significant ergonomic hazards. Addressing this gap, the present study aimed to assess the occupational health, safety, and ergonomic risks facing workers in ice production facilities. This cross-sectional descriptive study investigated production workers who were employees in two of eight ice manufacturing plants in Surat Thani, Thailand, using the Rapid Entire Body Assessment (REBA) method. A structured occupational health and safety risk assessment questionnaire and the REBA evaluation form were used to collect data. All participants were male, averaging 30.4 (±8.5) years old. Regular pain areas included the upper/lower back, hips/thighs, shoulders, wrists, and ankles. Ergonomic assessments showed high overall risk due to heavy lifting, repetitive tasks, and cold environments. Based on REBA scores, 13.04% were in the very-high-risk group (score ≥ 11) and 65.22% in the high-risk group (score 8–10). Most production workers in ice plants faced high ergonomic risks, especially from postures affecting the upper and lower back. Training should be provided to promote awareness of risky postures and proper lifting techniques. Mechanical aids and back-support equipment are also recommended to help prevent musculoskeletal injuries.

Organizational Career Growth, Employee Voice, and Work Engagement: A Multigroup Analysis of Hotel Managers and Staff

ABSTRACT This study examines how organizational career growth influences work engagement through employee voice and whether this process differs by job position. Drawing on the job demands–resources (JD‐R) model, social exchange theory, and self‐determination theory, this study applies partial least squares structural equation modeling (PLS‐SEM) and multigroup analysis to test the proposed model through an examination of survey data from 397 hotel employees in Thailand. The findings indicate that employee voice mediates the positive relationship between organizational career growth and work engagement. The effect of voice on engagement also differs between managerial and nonmanagerial employees. These results highlight the importance of fostering career growth opportunities and promoting voice systems to enhance engagement in the hospitality sector. Practical implications are provided for hotel HR departments, including strategies to design career development initiatives and strengthen communication mechanisms that address the distinct needs of managers and staff.

Azimuthal Directivity Evident in the Regional Amplitude and Duration of Ground Motions from the 2025 Mw 7.7 Mandalay Earthquake

Abstract The 28 March 2025 Mw 7.7 Mandalay earthquake produced long-period ground motions that propagated throughout mainland Southeast Asia. Although the supershear rupture along the Sagaing fault has been documented, its influence on regional shaking has not yet been quantified. Earlier work by Ornthammarath et al. (2025) focused mainly on long-period basin amplification in Bangkok. The present study expands the analysis to quantify amplitude and duration characteristics using 30 three-component strong-motion recordings from Myanmar and Thailand. We analyze amplitude and duration residuals relative to Next Generation Attenuation-West2 ground-motion and duration models. The results reveal a pronounced azimuthal pattern: stations located between 110 and 155 azimuth degrees from the rupture fault aligned with the Mach fronts of the southward-propagating supershear rupture exhibit large positive spectral acceleration residuals and strongly negative D5–95 duration residuals. In contrast, stations southwest and west of the rupture (e.g., Yangon and Nyaung U, respectively) show negative amplitude residuals and positive duration residuals. This bilateral contrast closely matches the expected Mach cone radiation pattern of a supershear rupture, demonstrating that regional ground motions (150–600 km) may retain the geometric imprint of the rupture-front speed. These findings suggest that supershear-related directional effects may persist beyond the near-fault region and contribute to far-field amplification patterns, with potential implications for incorporating rupture dynamics and a fault-to-site azimuth parameter into ground-motion models used in seismic hazard assessments of large strike-slip faults in similar tectonic environments.

Comparative Study of Rhodium Recovery from Plating Solutions via Cementation, Chemical Precipitation and Electrowinning

Rhodium plating is currently in appreciable demand not only for automotive as in catalyst converter but also for jewelry industry due to its silvery-white appearance, allergy-friendly, durable, scratch and tarnish-resistant. In accordance with circular economy, to assure efficient reuse and deviating from primary resource reliance, rhodium recovery is therefore of significance as the secondary resources. This research investigated comparative study of rhodium recovery from the plating solution via three techniques: cementation, chemical precipitation and electrowinning. The fresh plating solution prepared from rhodium concentrate and additive solutions was diluted to 0.1, 0.2 and 0.4 g/L of rhodium and used as the equivalent spent plating solutions. It was found that both cementation using zinc powder and chemical precipitation using sodium hydroxide and ammonium hydroxide did not yield notable recovery and gave low purity recovered products. Electrowinning has shown be more effective among the three techniques. For electrowinning, the diluted solutions were used as electrolyte, while the current density was controlled at 0.08-0.14 A/cm 2 for 2-24 h. Rhodium could be obtained at the cathode, giving the average rhodium content of 94.02 wt.% and the purity of greater than 98%. At the greater rhodium concentration of 0.4 g/L, deposition of rhodium metal was uniform appearing as clusters of particles on the cathode surface where nucleation and growth are competitive.

Antipyretic and Antinociceptive Activities of Tri-Phol-That Extract and Its Flavonoids: In Vivo and In Silico Evidence

High Resolution Image Download MS PowerPoint Slide Despite the common use of herbal medicines rich in flavonoids to treat fever and pain, the pharmacological mechanisms involved in these effects are poorly understood. Therefore, this study assessed the antipyretic and analgesic effects of Tri-Phol-That extract, characterized its major flavonoids, and investigated its possible molecular interactions with key inflammatory mediators. The antipyretic activity was evaluated against a turpentine-induced pyrexia model in mice. Analgesic activity was evaluated using the acetic acid-induced writhing, tail immersion, and hot plate tests. The concentration of rutin, quercetin, and kaempferol was determined by high-performance liquid chromatography. Molecular docking was performed using GNINA against COX-2 (mouse: 1CX2, human: 5KIR), COX-1 (ovine: 3N8X), and mPGES-1 (human: 4YL1). Interaction profile studies were also performed in the Discovery Studio 2021. The hydroethanolic extract lowered rectal temperature in a dose-dependent manner, with maximum inhibition occurring at 100–200 mg/kg, although the effect was less potent than that of tolfenamic acid. The acetic acid-induced writhing test also showed strong dose-dependent peripheral antinociceptive activity with 84.64% inhibition at 200 mg/kg of extract, comparable to tolfenamic acid. The central analgesic effects of extracts were observed in hot plate tests. Weak central analgesic effects were also observed in tail immersion tests. HPLC analysis indicated rutin (4.01 μg/g), kaempferol (2.13 μg/g), and quercetin (0.96 μg/g) were the most abundant flavonoid compounds. Based on docking results, quercetin had the strongest binding affinity toward COX-2 (−8.44 kcal/mol). Rutin also exhibited the strongest binding affinity toward…

Environmental Stability and External Environmental Dependency Analysis of Vertical Farm Remodeled from Agricultural Shelter House

This study proposes a model for constructing an energy-efficient vertical farm by retrofitting an existing agricultural facility, specifically an Agricultural Shelter House ("Nongmak house"), and evaluates its performance.An eight-layer composite thermal insulation covering system was applied to a 231 m 2 (70 pyeong) agricultural shelter house, which was converted into a closed-type vertical farm.To quantitatively assess the thermal insulation performance and environmental stability of the retrofitted system, the U-value was measured, and the internal and external environmental data were analyzed.Environmental stability was defined as the degree to which optimal internal environments (temperature, humidity, etc.) for crop growth can be maintained within a certain range regardless of external environmental changes, which is essential for minimizing crop stress and creating efficient cultivation environments.The calculated U-value of the composite insulation system was 1.939 W/m 2 •K.Although this value does not reach the level of conventional container-type vertical farms (0.193-0.225W/m 2 •K), it exhibits superior performance compared to single-layer PE film greenhouses (6.476 W/m 2 •K) and high-performance triple-layer thermal curtain systems (2.73 W/m 2 •K).Furthermore, the analysis of external climate, conventional greenhouse, and vertical farm internal environments demonstrated that the retrofitted vertical farm maintained highly stable conditions, with a temperature coefficient of variation (CV) of 5.85% and a relative humidity CV of 11.58%.Compared to external and conventional greenhouse environments, this structure provided significantly enhanced environmental stability.Statistical analysis using independent t-tests confirmed that the vertical farm showed…

Metabolomic Differentiation and Chemotaxonomic Insights into Three Korean Alnus Species Revealed by UPLC–QTOF/MS

High Resolution Image Download MS PowerPoint Slide Alnus species distributed on Ulleung Island, South Korea exhibit persistent taxonomic ambiguity due to high morphological similarity and limited genetic divergence within the green alder complex. To establish chemically discriminatory criteria for species delimitation, UPLC–QTOF/MS-based untargeted metabolomic profiling was applied to Alnus alnobetula subsp. fruticosa (AA), Alnus incana subsp. hirsuta (AI), and Alnus firma (AF). Multivariate statistical analysis revealed reproducible metabolome-level differentiation among the three taxa. Among 47 annotated secondary metabolites, statistically significant discriminant features were defined as marker metabolites. Biosynthetic interpretation showed that these markers were structurally concentrated within distinct metabolite classes and selected discriminant markers were structurally confirmed. Alnustic acid-related secodammarane-type triterpenoid markers were consistently detected in AA and AF but absent in AI, providing a chemical criterion for exclusion of AI. In contrast, separation between AA and AF was driven by quantitative differences in conserved diarylheptanoid and flavonoid markers. Functional evaluation further demonstrated metabolite class-dependent biological activities. Collectively, integration of statistical prioritization, biosynthetic interpretation, structural validation, and functional assessment establishes a marker-based chemotaxonomic framework for resolving taxonomic ambiguity within Korean Alnus taxa.

A Study on the Synergistic Development of Declarative Lexical Knowledge Representation and Cognitive Abilities in Adult EFL Learners Empowered by Word Embedding Models in the Era of Data Intelligence

In recent years, artificial intelligence technology has made significant strides in the field of education. Word embedding models, as a type of language generation model based on natural language processing, possess the ability to engage in real-time dialogue with students, offering a new form of support for vocabulary learning among English learners. Using the PyTorch deep learning framework, we constructed a word embedding model based on neural networks to design a word association memory system environment and conducted a 12-week experimental study involving 60 adult EFL learners. The results show that the average total scores for the participants’ declarative vocabulary knowledge breadth and depth tests were 92.11 and 105.19, respectively, and that the word embedding model was able to enhance the development of cognitive abilities. Furthermore, at the macro level, the scale of the second-language vocabulary semantic network expanded, its diameter increased, and its small-world characteristics were enhanced, while the network’s density and centrality decreased. At the macro level, the network’s modularity increased, and semantic partitioning became clearer. At the micro level, central words remained relatively stable, but the specific positions of most words within the network fluctuated significantly; English proficiency did not affect vocabulary connections. Strategic awareness can be strengthened, learning interest stimulated, language input increased, vocabulary strategies optimized, language output emphasized, and cooperative learning encouraged.

How to make Western Indian Ocean’s small-scale fisheries more sustainable

Small-scale fisheries in the Western Indian Ocean are vital to food security, livelihoods, and coastal economies, supporting over 65 million people. Yet, SSFs face mounting threats from various factors, including overexploitation, climate change, and weakly integrated governance systems. Despite growing evidence of climate impacts, critical gaps remain in understanding how these changes affect fisheries and in translating this knowledge into effective policy and practice. This policy brief highlights the urgent need to strengthen the science–policy–practice nexus, enhance cross-sector coordination, and embed climate resilience into fisheries governance to secure sustainable and equitable fisheries management outcomes for the region.

Budo architecture: an alternative model of the panopticon

This article proposes budo architecture as an alternative model of the panopticon. By “alternative,” it refers to Japanese martial arts environments where panoptic order, hierarchy, repetition, and continuous visibility do not merely produce docile bodies for institutional utility, but support self-discipline and ethical self-cultivation grounded in budo philosophy. While Michel Foucault frames modern institutions as spatial apparatuses that normalize bodies through surveillance and routine, budo operates as a “do” (way) that integrates mind, technique, and body (shin–gi–tai) and orients practice toward responsibility and mutual welfare. Using a qualitative, theory-driven case study design, the study surveys 11 historical and contemporary budo facilities and conducts a comparative deep analysis of Kyoto Budo Center, Kodokan, and Nippon Budokan. Architectural plans are redrawn to a consistent scale and analyzed through taxis (overall ordering), spatial hierarchy, sightlines and gaze, thresholds and circulation, and interior atmosphere. The findings show shared panoptic features across all three halls, legible open practice fields, rank inscribed in position, and continuous visibility. However, Kyoto Budo Center and Kodokan also mobilize controlled shadow, ma (interval), engawa, and kamiza-oriented symbolism to invite introspection. The article theorizes this as a budo-oriented panopticon, redirecting discipline toward self-forming practitioners rather than passive subjects.
