This study investigates the key determinants influencing the adoption of electric vehicle (EV) charging station applications in central Thailand, incorporating user views through technological acceptance models. A quantitative approach was employed, polling 206 electric car users throughout the four provinces with the largest number of public EV charging stations (38%): Bangkok, Nonthaburi, Samut Prakan, and Pathum Thani. This study combines the Unified Theory of Acceptance and Use of Technology (UTAUT2) with the Information Systems Success Model to assess the impact of Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Effort Expectancy (EE), and Facilitating Conditions (FC) on the quality of information, systems, and services in electric vehicle (EV) charging applications. The results indicate that the user demographic is primarily female (58.3%), with a significant portion aged 28–37 years (49.5%). Furthermore, 89.8% of participants possess a bachelor’s degree or higher. Usage of public charging stations is moderate, with 64.4% of users charging 1–2 times per week, which is lower than frequencies observed in comparable studies conducted in Europe. The findings indicate that EE and PU are the primary determinants of adoption, with EE being essential for system quality and PU exerting a positive effect on all quality dimensions. Facilitating conditions significantly influence information quality, with service quality identified as the most robust predictor of overall satisfaction. The research underscores ongoing fragmentation within electric vehicle applications, especially in developing markets. These insights offer critical guidance for developers, policymakers, and other stakeholders, highlighting the necessity of user-centered design, integrated solutions, and high-quality services to promote EV adoption and facilitate Thailand's transition to sustainable transportation. As supplementary information for product development aimed at entrepreneurs in the domain of application development for public electric vehicle charging stations in Thailand.

Existing research lacks focus on the structural behavior of reinforced concrete (RC) one-way slabs reinforced with ferrocement, and there's a notable absence of comparative studies between fiber-reinforced polymers (FRPs) and ferrocement strengthening methods for these slabs. Given the cost-effectiveness and widespread use of ferrocement in structural reinforcement, this study aimed to address these gaps through an experimental program. Three sizes of wire mesh, categorized as Type-I (small), Type-II (medium), and Type-III (large), were employed in this study. Chemical or mechanical anchors were used to attach ferrocement jackets. Moreover, 6, 12, or 18 anchors were used to assess the effect of anchor configuration. The goal was to enhance the structural performance of slabs and compare them with slabs reinforced using FRP jackets. The study focused on preventing debonding of the strengthening layers, employing either mechanical or chemical anchors. All slabs exhibited ductile failure with flexural cracks. The peak load and ultimate deflection were enhanced by up to 49.00% and 109.07%, respectively, by the application of ferrocement jackets, whereas the dissipated energy was increased by up to 174.00 %. Notably, the use of chemical anchors demonstrated a superior ability to delay debonding and enhance ductility compared to mechanical anchors. Slabs reinforced with glass FRP (GFRP) showed delayed debonding relative to carbon FRP (CFRP) reinforced slabs, indicating the superior performance of chemical anchors with GFRP layers. Moreover, the type and size of wire mesh significantly influenced performance, with small and medium-sized mesh configurations enhancing ductility, while large-sized mesh exhibited relatively earlier debonding. The orientation of the wire mesh also played a crucial role, with parallel orientation to the longitudinal axis of slabs yielding better performance.

Electric vehicles (EVs) are considered to be a solution for sustainable transportation. EVs can reduce fossil fuel consumption, greenhouse gas emissions, and the negative impacts of climate change and global warming, as well as help improve air quality. However, EV adoption in Thailand is quite low. Against this backdrop, this study investigates barriers and motivators for EV adoption and their public perception in Thailand. A total of 454 responses were collected through an online questionnaire. The results indicate that the top three concerns of respondents about EVs are public infrastructure and vehicle performance in terms of charge range and battery life. Respondents with more than five years of driving experience in the age range of 26–35 years old could be key targets for early EV adoption.

The critical nature of road logistics industry process capability's role in sustainable tourism development
(2019-01-01)

Globally, logistics cost an average of 11% of a country's gross domestic product (GDP). Furthermore, Thailand's 40 million foreign tourists are provisioned by a logistics system which relies on roads 97.68% of the time to deliver nearly half a billion tonnes of goods. However, Thailand has national logistics' cost averaging 14% of its GDP. With Thailand's revenues from logistics reaching $96.5 billion in 2019, the authors saw the importance of undertaking a study to determine how the Thai road logistics industry process capability (PC) is influenced by knowledge absorption capability (KAC), technology capability (TC), product innovation (PI), and service innovation (SI). By use of multi-stage random sampling, a sample of 483 owners, executives, and managers was obtained, whose responses from the seven-level scale questionnaire were analysed using LISREL 9.10 software. From both the initial CFA and final SEM of the eight hypotheses model, all the model's causal variables were found to influence PC positively. This can be explained by 81% of the variance in the Thai road logistics industry PC (R<sup>2</sup>). The causal variables influencing Thai logistics industry PC ranked from highest to lowest were KAC, TC, PI, and SI, with total effect (TE] values at 0.90, 0.81, 0.30 and 0.10, respectively. Therefore, in a smartphone-enabled, Internetconnected, social media world, Thai road service organizations need to marry 'technological innovation' process capabilities to ensure a competitive advantage and survivability. However, the need for a digitally enabled, 21st-century knowledge worker becomes even more crucial, but companies find obtaining these workers a difficult task, with Thai educational systems hard-pressed to deliver them. As a result, Thailand needs to educate and train a new generation of workers in the transportation and logistics sectors.

State railway of thailand employee performance: a structural equation model analysis

Dropping from a peak of 88 million riders in 1994, Thailand’s state railway system today is only transporting 35 million passengers annually. Operations run at a loss, with infrastructure and aged equipment contributing to significant delays, and a continuing loss of passengers. However, in September 2017, a new 20-year US$81.57 billion plan was introduced to save the State Railway of Thailand [SRT] from its death spiral. Given the magnitude of the problem, this study aims to analyze employee performance of SRT civil servants. Using multi-stage random sampling, 360 individuals were selected; through a five-level, Likert type agreement scale questionnaire, 54 items concerning their characteristics, their perspectives on SRT’s organizational culture, human resource management processes, the SRT’s total quality management program, and their effect on employee performance were analyzed. From the data, LISREL 9.1 was used to conduct a confirmatory factor analysis and structural equation model to analyze the results. The structural equation model [SEM] results showed that all the causal factors in the model were shown to have a positive influence on SRT employee performance, which is explained by the variance of factors influencing SRT employee performance (R<sup>2</sup>) by 92%. Ranked in importance, the results determined that human resources [HR=0.96], had the most significant impact on employee performance [EP], followed by total quality management [TQM=0.45], and finally, organizational culture [OC=0.37].
