Evaluation of the potential of market entrance into the personal luxury goods resale market in Thailand
The resale of luxury goods is a relatively new phenomenon that globally shakes up the luxury industry. Despite having a second-hand luxury market in place, the Thai market lacks service quality in international comparison, leaving the potential for companies to enter the market and close the quality gap. Past research focused on consumer behavior in relation to luxury consumption (Eastman et al., 1999), service quality (Parasuraman et al., 1988) as well as the relatively new pattern of second-hand consumption (Roux & Guiot, 2010). This study combined these approaches to evaluate the potential of market entrance into the personal luxury goods resale market in Thailand and addressed the questions whether there is potential for a second-hand luxury reselling business in Thailand and which service parameter is most important for Thai customers.
In order to answer these questions, the Thai market is analyzed with a review of secondary sources and through quantitative research methods (i.e. online consumer survey), measuring the Thai consumers’ attitude towards luxury and second-hand consumption of personal luxury goods. The survey also included a section on service quality that sought to answer the second research question concerning the importance thereof.
The general market environment and the willingness of Thai consumers to engage in second-hand consumption of personal luxury goods suggest that there is potential for a second-hand luxury reselling business in Thailand. Furthermore, the results indicate, that Assurance is the most important service dimension for Thai consumers
Detection Sensitivity of a Modified EWMA Control Chart with a Time Series Model with Fractionality and Integration
Among the many statistical process control charts, the modified exponentially weighted moving average (EWMA) control chart has been designed to swiftly detect a small shift in a process parameter. Herein, we propose two explicit formulas for the average run length (ARL) for integrated moving average (IMA) and fractional integrated moving average (FIMA) models combined with the modified EWMA control chart for time series prediction. The application of the suggested control chart procedures depends on the residuals of the IMA and FIMA models. The performance of the control chart with both models is evaluated by using the ARL. Explicit formulas for the ARL for the two models with the modified EWMA statistic are derived and their precision is compared with the numerical integral equation method. The explicit formulas could accurately predict the true ARL while markedly decreasing the computational processing time compared to the numerical integration method. The capabilities of the IMA and FIMA models with the modified EWMA control chart were studied by varying g times the last term and exponential smoothing parameter λ, with the relative mean index being used to evaluate these situations. The results show that the modified EWMA control chart with either model performed better than the original EWMA control chart. Furthermore, the modified EWMA control chart with either model was highly efficient when g increased and λ was small. Two applications involving energy commodity prices are used to illustrate the efficacies of the proposed approaches, the results of which were in accordance with the experimental study.

Climatic Factor Differences and Mangosteen Fruit Quality between On- and Off-Season Productions
The objective of this study was to investigate the differences in climatic factors and fruit quality between on- and off-season production periods. Climate, soil, and mangosteen measurements were all studied during on- and off-season production. We chose 40 mangosteen trees and observed flowering and fruit set rates over two production periods. The results showed that the number of flowers per branch, the number of fruits per branch, the circumference of fruits, and the fruit weight were higher during the on-season mangosteen production period than during the off-season mangosteen production period. However, the number of edible pulp segments, peel thickness, percentage of translucent flesh, and fruit gumminess were lower in the on-season mangosteen production period than in the off-season mangosteen production period. The percentage of fruit scars did not differ between the on- and off-season mangosteen production periods. When compared to the on-season mangosteen production period, there was lower relative humidity, soil moisture at 120 cm depth, and leaf wetness at 15 cm above ground during the off-season mangosteen production period; however, there was higher air temperature, soil moisture, and soil temperature at all four depth levels.

Optimal Multi-Reservoir Operation for Hydropower Production in the Nam Ngum River Basin
This research aims to investigate optimal hydropower production of multi-reservoirs in Lao PDR and develop optimal reservoir rule curves. The Nam Ngum 1 and 2 (NN1 and NN2, respectively) reservoirs in the Nam Ngum River basin (NNRB), which is located in the middle of Laos, are selected as study areas. Mixed integer nonlinear programming (MINLP) is developed as an optimization model to maximize the hydropower production of joint reservoir operation of NN1 and NN2. The optimal operation rule curves are established by using the storage level estimated by the optimization model. Given the limited sideflow data, an integrated flood analysis system (IFAS) and water balance equation are used to simulate the sideflow into NN1 reservoir. A good fit is observed between the monthly streamflow simulated by IFAS and that calculated by the water balance equation. Compared with the observed data, the MINLP model can increase the annual and monthly hydropower production by 20.22% (6.01% and 14.21% for NN1 and NN2, respectively). The water storage level estimated by the MINLP model is used to build the operation rule curves. Results show that the MINLP model of multi-reservoir is a useful and effective approach for multi-reservoir operations and is expected to hold high application value for similar reservoirs in NNRB
