Objective: To assess secondhand smoke (SHS) exposure in Thai international airports using a fine particulate indicator, particulate matter ≤2.5 μm (PM2.5), and to compare with 2012 exposure findings in international airports in the USA.
Methods: Smoking rooms in the four largest international airports that serve the most travellers and with the most operating designated smoking rooms (DSRs) were monitored using PM2.5 monitoring equipment following an approved research protocol for assessing fine particle pollution from tobacco smoke. Monitoring was conducted inside and just outside DSRs and throughout the airport terminals in all four airports. Altogether 104 samples were taken to assess SHS exposure in four airports. Simultaneous samples were taken multiple times in a total of 11 DSRs available for sampling in the research period.
Results: Levels of PM2.5 in DSRs were extremely high in all four airports and were more dangerous inside DSRs than in the US airports (overall mean=532.5 vs 188.7 µg/m(3)), higher outside DSRs than in the US airports (overall mean=50.1 vs 43.7 µg/m(3)), and at comparable levels with the US airports in the terminals away from DSRs (overall mean=13.8 vs 11.5 µg/m(3). Findings show that travellers and employees in or near DSRs in the airports assessed in Thailand are being exposed to even higher levels of SHS than in US airports that still have DSRs.
Conclusions: Extremely high levels of SHS in and adjacent to DSR show that these rooms are not providing safe air quality for employees and travellers. These high levels of exposure are above those levels reported in US airports and show the need for remedial action to ensure safe air quality in international airports in Thailand.

Customized nano-biocatalysts of laccase have been made using nano-structured polyaniline viz. nano-fibers and nano-tubes, as immobilization supports and a simultaneous comparison between them has been made. Laccases are poly-phenol oxidases having tremendous utility concerning wider areas of application especially in the field of organic and drug syntheses.

The development of biofuel technologies depends on the accurate identification and quantification of products from the conversion processes. Given the complexity of the renewable resources, the availability of biomass, and the versatility of conversion methods, there is a need for characterization methods that provide rapid and reliable analysis for various products coming from different conversion processes with minimal sample preparation. This study develops and validates gas chromatography methods that use multiple detectors to analyze pyrolytic compounds in both gas and liquid phases efficiently in a single, rapid run.

To improve students' understanding of physical education teaching concepts and help teachers analyze students' cognitive patterns, the study proposes an association learning-based method for understanding physical education teaching concepts using deep learning algorithms, which extracts image features related to teaching concepts using convolutional neural networks. Moreover, a neurocognitive diagnostic model based on hypergraph convolution is constructed to mine the data of students' long-term learning sequences and identify students' cognitive outcomes. The findings revealed that the highest accuracy of the association graph convolutional neural network was 0.

In February 2024, a 22-year-old Japanese resident of Osaka Prefecture was diagnosed with measles in the PCR test. He had flown from Dubai to Osaka Kansai International Airport. We finally detected 13 incident measles cases identified as infected by the index case and collected data on these individuals to evaluate the association between vaccination and incubation period.
