This paper introduces a covering model for collaborative bidirectional multi-period vehicle routing problems under profit-sharing agreements (CB-VRPPA) in bulk transportation (BT) networks involving one control tower and multiple shippers and carriers. The objective is to maximize the total profits of all parties subject to profit allocation constraints among carriers, terminal capability limitations, transport capability limitations and time-window constraints. The proposed method includes three stages: (a) generate all feasible routes of each carrier, (b) eliminate unattractive feasible routes via a proposed screening technique to reduce the initial problem size, and (c) solve the reduced problem using a branch-and-bound algorithm. Computational experiments are performed for real-life, medium- and large-scale instances. The proposed method provides satisfactory results when applied to solve the CB-VRPPA. We also conduct a sensitivity analysis on a critical parameter of the profit-sharing agreement to confirm the effectiveness of the proposed method.

On average, Guangxi experiences 2 severe tropical cyclone disasters yearly. A large number of disaster victims need governments at all levels to raise enough emergency supplies to carry out effective relief. However, there is no proper reserve center for tropical cyclone disaster storage and collection of emergency supplies in Guangxi, so it is urgent to choose a suitable location to build the Guangxi tropical cyclone disaster emergency supplies reserve center. The data of 16 severe tropical cyclone disasters and rescues in Guangxi from 2014 to 2021 were collected. An optimal location model of the emergency supplies reserve center for tropical cyclone disasters in Guangxi was established using the improved center of gravity method based on GIS. After four iterations of calculation, the longitude and latitude coordinate S5(108.64, 21.98) were used as a suitable site to construct the Guangxi Tropical Cyclone Disaster Emergency Supplies Reserve Center to ensure the fastest and lowest cost delivery of emergency supplies to the disaster areas in Guangxi. According to the map of Tiandi, the actual place corresponding to this coordinate is near Liuwu Village next to Qinzhou East Railway Station, Qinnan District, Qinzhou, Guangxi. This location coordinate S5 can provide a reference for the Guangxi Zhuang Autonomous Region government to select a suitable address to construct the Guangxi Tropical Cyclone Disaster Emergency Supplies Reserve Center. The improved center of gravity location model based on GIS can also provide a reference for other provinces or cities to carry out emergency supplies reserve center locations.

This research aimed to study the antecedents and consequences of brand coolness for fashion clothing brands in the millennial consumer context. The data was collected through an online questionnaire on 380 consumers who used to buy brand-name fashion clothing. The data were analyzed using the structural equation model. The results showed that the antecedents of brand coolness consisted of brand experience and brand identification, both of which positively influence brand coolness. Brand coolness (i.e., reference, singular, personal, esthetic, functional, energetic, and high status) was the key driver that creates brand equity. The research results were able to explain 94% of the variance in brand coolness and 81% of the variance in brand equity. This research is empirical support that helps expand the perspective on brand coolness and presents a dimension to measure brand coolness in a more transparent and complete method. The research result also complements the marketing knowledge that can guide academics and practitioners in creating substantial brand equity in the customers' hearts.

Smart farming is a feasible solution to help farmers effectively and sustainably manage the potential threats and risks those traditional farmers face, such as product quality, increased production costs, the environment, climate change, natural catastrophes, pests, and inferior goods. Using a survey research design, this research examined smart farming adoption and risk management models by combining the Technology Acceptance Model (TAM) and the Innovation Diffusion Theory (IDT). The research sampled 400 farmers who are members of community enterprises in the northeastern region of Thailand. Data was collected using a questionnaire and analyzed using a statistical package program in four steps: confirmatory factor analysis, path analysis, structural equation model analysis (SEM), and Sobel's test. The findings revealed that government support variables had the most significant influence by adopting smart farming to risk management. Based on the research results, the government can apply this model to create strategies to encourage farmers to adopt smart farming and increase the production efficiency of agricultural products. The farmer can manage the risks of smart farming, which leads to sustainable smart farming and is useful for further academic acceptance and risk management studies. Furthermore, this study contributes to the existing literature on combining TAM and IDT in model adoption and risk management. The limitations include the small sample size adopted and the limited coverage area for the study, which restricts the generalization of the findings. However, the findings offer a glimpse into the benefits of smart farming.

Better implementation of Industry 4.0 showed a positive effect on SSC. In addition to this, Industry 4.0 had a positive effect on data storage, data assessment, performance evaluation and data inquiry. Finally, data storage, data assessment, performance evaluation and data inquiry had a positive effect on SSC.

This research aimed to study the approach of the community toward the decision to grow rice and economic crops, including appropriate resource allocation for use on a farm under a large plot agricultural system. The study areas were in Phan district, Chiang Rai province, Thailand, and the data were collected from a sampling of 400 field agriculturalists. The method used was to develop a mathematical model for growing crops with multi-objectives and in multi-periods, together with an agriculturist representative and experts in multiple-criteria decision-making (MCDM). This was to prioritize the importance of alternative crops and find the appropriate allocation of the resources to achieve the targeted goal. The results showed that agriculturists prioritized most toward the criteria for growing Japanese rice with a weight of 0.179 Kg., followed by transplanted rice, transplanted glutinous rice, garlic, sown paddy rice, and sown glutinous paddy rice, respectively. The study’s results also showed that the price fluctuation of the crop products resulted in more use of land and labor in order to increase the production to compensate for the low price, and this also resulted in the higher opportunity cost of growing transplanted rice. Therefore, growing transplanted rice during in season planting was considered the most effective way, while during the off season, either garlic or Japanese rice could be grown. A collective pattern for planning for using resources together in large plot agricultural areas, together with a clear marketing target would bring about effective use of the resources and reduce the risk in revenue from the fluctuation in prices and uncertainty of yields from drought. Moreover, technology development to solve the problem of the lack of labor would be deemed an important approach toward the enhancement of the competitiveness of agriculturists in the future as well.

Red jasmine rice is recognized as a healthy food with high phenolic compounds. These compounds present antibacterial and anti-free radical properties. Moreover, colored rice exhibits a biological activity against anticancer. Objectives of this study are 1) exploring a biological screening and cell viability of 70% ethanol and aqueous extracts of red jasmine rice, 2) investigating cytotoxicity to fibroblast NIH3T3 (IC80) that is one hundred cells were found cell viability 80 cells. Red jasmine rice extracts were dried and transformed into a powder using the freeze-drying method. The extracts were treated with fibroblast NIH3T3 for MTT. The highest of IC50 of red jasmine rice extract to scavenge the DPPH and ABTS radicals was found in ethanol extract (53.20±7.37 and 64.17±5.76, respectively). The experiment showed that the ethanol and aqueous extract of red rice did not show cytotoxicity to fibroblast NIH3T3 (IC80). The extracts of red rice show the biological screening of anti-oxidation with total phenolic compounds and flavonoid contents. Moreover, it does not modify the physical properties of the cream formula. It can be concluded that the red rice extract is highly promising for the value addition.

Aged workers were mostly questioned in terms of their work efficiency. However, as time changed and the structure of human resource in the organization also changed, older people became important part of all human resources in the organization. The study, hence, aimed 1) to study the level of work efficiency of aged workers; and 2) to study factors affecting work efficiency of aged workers. The study applied quantitative method using questionnaire as a data collection tool, collecting data from aged governmental officers in Nong Khai province, Thailand. There were 402 completed questionnaires which were taken for analysis. The finding presented that aged workers performed very high level of work efficiency using frequency, mean, and standard deviation techniques to analyze. To find the factors affecting work efficiency, the research applied multiple regression analysis. The finding presented that recognition and respect, fair evaluation, job design, and compensation were factors affecting work efficiency of aged governmental officers.

The performance plays a key role in the long-term survival of the organizations. If the performance of the organization increases, then the organization may lead in the global perspective. There are various factors that could lead to the performance. Among those, the supply chain management practices (SCMP) play an important role to increase the performance. The SCMP factors may also enhance the competitive advantage of the organizations. Furthermore, the manager support may provide insight to manage the SCM activities which could aid enhance firm performance (FP). Therefore, the purpose of this study is to investigate the relationship between the SCMP and FP with the moderating and mediating effect in the chemical industry of Thailand. The data was collected from the supply chain managers by using a simple random technique. The SEM direct effect shows that SCMA had a significant and positive connection with firm performance FP. In addition, SCMP does not seem to have any significant relationship with the competitive advantage. While competitive advantage has a positive and significant effect on FP. On the other hand, the indirect effect shows that SCMP and FP relationship were partially mediated from the competitive advantage. Moreover, the manager's support did not significantly moderate the SCMP and FP relationship. The current study added literature in the extant literature in the form of empirical findings which could help the researchers explore their studies in future. The study may also provide help to owners as well as to shareholders to know about the importance of the SCMP, competitive advantage and managers' support to increase their FP.

This research aimed to investigate the effect of leader-member exchange and employee motivation on organizational commitment, and the effect of organizational commitment on job performance. The research also examines the moderating effect of generation on the relationship between organizational commitment and job performance. The population of this research is the employees working in private organizations in Thailand. Data collection was performed using a convenient random method. 400 usable questionnaires were used for statistical analysis. The author analyzed Descriptive statistics by SPSS program version 25 while the SmartPLS 3.3.0 program was used to test the research hypotheses in Partial Least Square-Structural Equations Model (PLS-SEM). The finding revealed that leader-member exchange positively affected organizational commitment but employee motivation had no significant effect on organizational commitment. It also found that leader-member exchange had a positive effect on employee motivation. Another key point was organizational commitment significantly influenced on job performance. In addition, the study found the moderating effect of Generation on the relationship between commitment and job performance.
