The purposes of this quantitative research are (1) to study factors affect the digital-era job performance of accountants; (2) to study the use of technology in accounting work and the satisfaction of accountants by applying appropriate tools and technology and; to study the digital-era professional competence of accountants. The research instrument is a questionnaire which was used to collect data from accounting managers of the listed and non-listed companies approved by the Securities and Exchange Commission; auditing firms; and accounting firms in 2020. The results reveal 33 variables consisting of five components which are (1) professional development (2) technical competence (3) employee engagement (4) organizational and communication and (5) professional attitudes and ethics. Objective one all five components were analyzed by the multiple regression analysis to find the correlation with the variables of digital-era job performance of professional accountants (p < 0.05). The results show positive relationship of (1) professional development; (2) the technical competence; (3) the employee engagement; (4) the organizational and communication and; (5) the professional attitudes and ethics to high digital-era job performance of accountants (p < 0.05). In addition the most accounting managers have a high level of satisfaction by adopting tools and technology. Finally they have a high expectation of professional competencies in the technical competence; the professional attitudes and ethics; the professional skill interpersonal and communication and organizational.

This research aims to 1) analyze the SMEs 4.0 market management factors for Thai clothing brands among generation Y 2) to study personal factors affecting the SMEs 4.0 market management for Thai clothing brands among generation Y and 3) to generate the SMEs 4.0 market management model for Thai clothing brands among generation Y. This study uses qualitative and quantitative research methods. In-depth interviews served as a qualitative data collection methodology. Seventeen participants were grouped into experts stores managers and specialist contemporary Thai clothing brands. For the quantitative data collection methodology the researcher used questionnaires with a specific group of 430 Generation Y male and female participants who used to purchase or frequently purchase Thai clothing brands. To analyze data percentage mean and multiple classification analysis with a statistically significant level at 0.05 the researcher used G*power. Furthermore it was analyzed if the results were consistent with the qualitative data. The research results show that market management factors significantly relate to Thai clothing brand customers’ purchasing behaviors. These factors include purchasing rationale factor purchasing motivation factor brand management factor and demand management factor. The research findings link to the best practices in the market management model both online and offline markets and sustainable development in 5.0 society including 1) a rapid technology replacement 2) adding creative value to the society 3) natural harmonization management and 4) sustainable development.

The objectives of this research are to design the load cell tolerance testing machine and demonstrate the tolerance of load cell with a tolerance test that has a beam length of 90 cm. It can create the compressed force at the load cell more than 1 kN The experiment cam be divided into 2 stages; 1.) verification of load range and 2.) linearity test. Both stages are tested at a temperature at 25°C using 10 to 30 kg of mass in the lowest compressed force condition of 0.091 kN and the maximum compressed force condition of 1.12kN As a result the linearity performance of the tolerance of the load cell test kit between calculated force and displayed value force are different 0.354 percentage only while the standard deviation of displayed value force and voltage signal output are 0.0013 and 0.0022 respectively. It reveals that the experimental result is reliable because of less than 1. In addition the tolerance of the load cell tolerance testing machine is 0.00300 (0.3 percent) which was calculated from the comparison of the tolerance specification of two main equipment that specified by manufacturer.

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.

The purpose of the study was set to analyze the current situation of the competency of accountants model of small and micro community enterprise of central region in 2030.The study was examined through the perspective of a group of experts scrutinizing future feasibility the competency of accountants of of small and micro community enterprise of central region in 2030. The data were examined by delphi techniques with the data collected through the interviews and questionnaires from three different data collections. The data analysis was completed using median and consistency then confirmed the result with by the interquartile range calculation. It was found that the key components included 1. Knowledge and understanding of accounting and other fields 2. Experience skills and linking knowledge in many dimensions 3. Ethics 4. Soft skills of future forms of the competency of accountants model of small and micro community enterprise of central region in 2030 as examined and approved by the experts in all four skills for the feasibility of the future application.
