The Correlation among 5 Aspects of Service Quality in Thailand’s Low-cost Airlines

The purpose of this research was to study the relationship between five aspects of service quality factor of low-cost airlines in Thailand. The population of the research was people who had experience traveling with low-cost airlines in Thailand. 380 respondents are the sample size of this research. Information is collected through social media such as Facebook, Line. The research tool was a questionnaire developed from a review of the relevant literature. The main descriptive statistical analysis was frequency, percentage, mean, standard deviation, skewness, and kurtosis and the researcher analyzed the inferential statistics by using the Structural equation model analysis. Firstly, the results of the general data analysis showed that most of the respondents were female (64.7%), aged 20-40 years (76.2%), had a bachelor's degree (50.8%), and had a monthly income of more than 900 US dollars (39.5%). Secondly, it was found that the overall mean of the service quality variables was considered the highest level. When considering each aspect of service quality, it was found that all five aspects of service quality were at the highest level as well. And finally, the results of the study revealed a significant correlation between the five factors of low-cost carrier service quality. The results suggest that low-cost airline executives need to focus on high service quality in all five aspects: tangibility, reliability, responsiveness, assurance, and empathy. Paying attention to the customer needs and five aspects of service quality will contribute to the good performance of low-cost airlines such as having good competitiveness, higher growth, better operating results, and better business sustainability

Differential responses of hepatopancreas transcriptome between fast and slow growth in giant freshwater prawns (Macrobrachium rosenbergii) fed a plant-based diet

Abstract Efficient utilisation of plant-based diets in the giant freshwater prawn, Marcrobrachium rosenbergii, varies according to individual, suggesting that it might be associated with differences in physiological and metabolic responses. Therefore, we aimed to investigate the individual differences in the growth response of shrimp fed to a soybean-based diet (SBM). Two hundred shrimp were fed SBM for 90 days, and specific growth rate (SGR) was determined individually. Fast- and slow-growing shrimp (F-shrimp vs. S-shrimp), with the highest and lowest 5% SGRs, respectively, were sampled to determine haemolymph chemistry and carcass composition. The hepatopancreas of these shrimps were used for transcriptome analysis through RNA sequencing (RNA-Seq). The results showed no significant differences in haemolymph chemistry parameters. In terms of carcass proximate composition, F-shrimp exhibited higher protein composition than did S-shrimp, suggesting that F-shrimp have higher protein anabolism. Using RNA-seq and real-time reverse transcription polymerase chain reaction (qRT-PCR), the expression levels of several genes encoding physiologic and metabolic enzymes were found to be upregulated in F-shrimp compared to in S-shrimp, suggesting that these enzymes/proteins mediated the efficient use of SBM-based diets for growth promotion in shrimp. Various DEGs associated with the immune system were observed, indicating a difference in immune processes between F- and S-shrimp. The expression of several housekeeping genes was found to be upregulated in S-shrimp. Collectively, the upregulated expression of several enzymes associated with physiological and/or metabolic processes and increased protein anabolism may be attributed to the efficient use of SBM for maximal growth in shrimp
