This research investigates the synergistic relationships between Green Supply Chain Management (GSCM) practices and product innovation in marketing performance and organizational sustainability within Thailand’s processed food industry. Building upon Resource-Based View theory and Stakeholder Theory, this study addresses a critical gap in understanding how environmental practices interact with innovation strategies to create sustainable competitive advantages in emerging markets. The research employs a comprehensive mixed-methods approach, integrating qualitative insights from industry expert interviews with quantitative analysis through Structural Equation Modeling (SEM). Primary data were systematically collected from 300 strategically selected enterprises representing small (≤50 employees), medium (51–200 employees), and large-scale (>200 employees) operations across diverse product categories within Thailand’s processed food sector. The analytical framework examines three core GSCM dimensions—green purchasing, green production, and green distribution—alongside three innovation aspects—quality innovation, safety innovation, and sustainability innovation. Eleven hypothesized relationships were rigorously tested to examine direct and indirect effects on marketing performance indicators (sales growth, market share expansion, brand enhancement, customer satisfaction, and cost optimization) and organizational sustainability metrics (environmental impact reduction, regulatory compliance, competitive positioning, and resource efficiency). SEM results revealed that Green Production practices significantly enhance marketing performance (β = 0.16, p < 0.01), demonstrating the strategic value of environmentally responsible production processes in achieving market success. Conversely, Green Distribution exhibited negative effects on both marketing performance (β = −0.106, p < 0.10) and organizational sustainability (β = −0.152, p < 0.05), indicating potential operational trade-offs and infrastructure limitations that require strategic optimization. The model demonstrated excellent fit indices (GFI = 0.929, CFI = 1.000, TLI = 1.000, RMSEA = 0.000, RMR = 0.034), validating the theoretical framework’s robustness. However, modest explanatory power (R2 MP = 0.050, R2 OS = 0.029) suggests that additional contextual factors, firm-specific capabilities, and market dynamics significantly influence these outcomes, warranting future investigation of mediating and moderating variables.

This research employed a mixed-methods approach to explore the best practices of ordinary national educational testing (O-NET) to improve the quality of basic education. The methodology was divided into four phases, the first of which was a survey and analysis of the current situation at O-NET. The sample group was made up of representatives of the school under the office of the basic education commission (OBEC), primary education, comprising the school administrators and teachers teaching in four subjects. Phase 2, “multiple case study,” is qualitative research by selecting specific case studies for 10 primary schools based on criteria for selection and collecting data through in-depth interviews. A semi-structured interview form was completed by 30 key informants. Phase 3, the synthesis (draft) of best practices, and phase 4, the checking and proposing of best practices by 25 assessors. The results showed the best practices in using the test results of O-NET to improve the quality of basic education were 4 components: i) school management (16 practice guidelines); ii) learning management (10 practice guidelines); iii) student promotion (6 practice guidelines); and iv) parent communications (3 practice guidelines). The best practices were in accuracy, propriety, feasibility, and utilization; all were at the highest level.

The objective of this research is to develop the appropriate formula of kha nom thong muan from paka-umpoul defatted rice bran flour to develop as a snack with higher nutritional value. This study was done by planning a complete randomized design (CRD). The amount of paka-umpoul defatted rice bran flour substituted at 5 levels of 0, 10, 20, 30, and 40 % (formula 1, 2, 3, 4, and 5 respectively). It was tested for sensory quality using the 9-point hedonic scale scoring test using 30 semi-trained testers. It was found that the Thong Muan dessert product (formula 3) used paka-umpoule defatted rice bran flour substituted with wheat flour at the rate of 20 % received the highest overall liking score (7.82). The comparison between formula 3 and the basic formula (formula 1) in the physical, chemical, and microbiological quality found that the color values were significantly different at the 95% confidence level. By increasing the amount of defatted rice bran flour resulted in the brightness value (L*) decreased and the product became darker in color. In addition, the free water content (a w ) increased from 0.389 to 0.429. The chemical quality of fat, ash, and fiber was higher by 23.01%, 2.18%, and 2.16%, respectively. Analysis of gammaoryzanol and total antioxidant activity by DPPH assay was not found in the basic formula while was found in formula 3 at 0.031 mg per 100 and 19.05 mg per 100 grams, respectively. An examination of microbiological quality of formula 3 was found that there were coliforms <3.0 MPN/g. and yeast and mold <10 cfu/g. in Thai Dessert Community Product Standard Criteria (TCPS.1/2009).

The representatives of cyprinid lineage 'Poropuntiinae' with 16 recognized genera and around 100 species form a significant part of Southeast Asian ichthyofauna. Cytogenetics are valuable when studying fish evolution, especially the dynamics of repetitive DNAs, such as ribosomal DNAs (5S and 18S) and microsatellites, that can vary between species. Here, karyotypes of seven 'poropuntiin' species, namely Cosmochilus harmandi, Cyclocheilichthys apogon, Hypsibarbus malcomi, H. wetmorei, Mystacoleucus chilopterus, M. ectypus, and Puntioplties proctozysron occurring in Thailand were examined using conventional and molecular cytogenetic protocols. Variable numbers of uni- and bi-armed chromosomes indicated widespread chromosome rearrangements with a stable diploid chromosome number (2n) of 50. Examination with fluorescence in situ hybridization using major and minor ribosomal probes showed that Cosmochilus harmandi, Cyclocheilichthys apogon, and Puntioplites proctozystron all had one chromosomal pair with 5S rDNA sites. However, more than two sites were found in Hypsibarbus malcolmi, H. wetmorei, Mystacoleucus chilopterus, and M. ectypus. The number of chromosomes with 18S rDNA sites varied amongst their karyotypes from one to three; additionally, comparative genomic hybridization and microsatellite patterns varied among species. Our results reinforce the trend of chromosomal evolution in cyprinifom fishes, with major chromosomal rearrangements, while conserving their 2n.

Background. The ability to quickly change direction has been considered an important physical quality related to success in youth soccer. The study purpose was to investigate the training effect of a complex agility training program on amateur male soccer players. Materials and methods. The participants were 60 amateur male football players (aged 18-22) divided into two groups and selected by using purposive random sampling. Thirty athletes aged 19.7±1.34, BMI 21.8±1.75 performed a complex training program (CTG) combined with sprint, agility or CoD, and plyometric session. While 30 participants of the control group (CG) aged 19.3 ± 1.31, BMI of 21.2 ± 1.02 followed a general football training program. In both groups, each training session lasted 120 minutes, a 30-minute period, 3 times a week, a total of 6 weeks. The Arrowhead Agility Test was scheduled at the baseline, for the 4th and 6th weeks. The mean and standard deviation of the data was calculated. The inferential statistic was repeated measure ANOVA. A Newman-Keuls post hoc test was calculated if the group x time interactions were significant (p &lt; 0.05). Results. After training, agility was a statistical difference within the CTG, when comparing baseline and the 6th week (p = 0.03), there were no significant changes in agility when comparing between-group. Therefore, this shows that complex training programs can improve agility in amateur male soccer players. Conclusions. This integrated training program can be applied to amateur male soccer players. The training program should be specific and varied. It can help soccer players improve their agility that is related to overall soccer performance.

This research employed mixed method for development curriculum for primary Thai language teachers according to STREAM education. The participants were 17 volunteering primary Thai language teachers for curriculum development and 110 primary students from 6 primary schools for curriculum implementation. The findings revealed that teachers were well-versed in the STREAM education curriculum, and that instructional management was at a high level. Thai teachers were capable of developing a STREAM-based integrated curriculum and learning management system. Students can improve their reading, writing, and analytical thinking skills as a result of the implementation. The result is fruitful for teachers and students in self-development, learning skill, and learning competency by employing integrated approach. Indeed, STREAM education should be more continuously improved and invite to school curriculum and instructional practices based on different contexts.

Functionalities of 3D printing filaments have gained much attention owing to their properties for various applications in the last few years. Innovative biocomposite 3D printing filaments based on polylactic acid (PLA) composited with ZnO nanoflowers at varying contents were successfully fabricated via a single-screw extrusion technique. The effects of the varying ZnO nanoflower contents on their chemical, thermal, mechanical, and antibacterial properties were investigated using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and tensile testing, as well as qualitative and quantitative antibacterial tests, respectively. It was found that the ZnO nanoflowers did not express any chemical reactions with the PLA chains. The degrees of the crystallinity of the PLA/ZnO biocomposite filaments increased when compared with those of the neat PLA, and their properties slightly decreased when increasing the ZnO nanoflower contents. Additionally, the tensile strength of the PLA/ZnO biocomposite filaments gradually decreased when increasing the ZnO nanoflower contents. The antibacterial activity especially increased when increasing the ZnO nanoflower contents. Additionally, these 3D printing filaments performed better against Gram-positive (S. aureus) than Gram-negative (E. coli). This is probably due to the difference in the cell walls of the bacterial strains. The results indicated that these 3D printing filaments could be utilized for 3D printing and applied to medical fields.

Due to the widespread infection of the coronavirus (COVID-19) over the world, people were forced to stay at home, and technology has been increasingly used in communication, entertainment, and work. This research emphasized the study on the technology usage of Generation Z who are ready and highly skilled in using technology. The purpose of the study was to investigate the influence of key factors affecting the intended use and practical application of Generation Z technology in Cambodia during the COVID-19 pandemic. The researcher chose to use the UTAUT Model to test the research hypothesis. A questionnaire is a research tool used to collect data online. It was found that the sample size was 212 respondents. Descriptive analysis and the partial least square structural equation model (PLS-SEM) evaluation were performed. The results revealed that (1) most of the respondents were male, had under a bachelor’s degree, and monthly income was equal to or more than 312 US dollars, (2) the performance expectancy significantly influenced the behavioral intention, but effort expectancy, social influence, and facilitating conditions did not affect the behavioral intention of technology use, and (3) the behavioral intention to use technologies significantly influenced the actual use behavior during the covid-19 situation. This study suggests that technology organizations or businesses should pay attention to the potential benefits of technology for spurring the technology adoption and use of Generation Z people in Cambodia.
