The objectives of this research are to propose a Bayesian model for spatial time series analysis to apply the proposed model to forecast a monthly rubber yield in Southern provinces of Thailand and to compare the performance of the proposed model with the classical Holt-Winters Additive Exponential smoothing. The proposed model is a linear mixed model (LMM) with spatial effects which follow a conditional autoregressive model (CAR). Dummy variables are used for seasonal effects. A Bayesian method is used for parameter estimation. The estimated monthly yields are used for the monthly rubber yield forecasting. The dependent variables are the rubber yield in each month of each province. The data are secondary data at a provincial level. The factors considered are spatial effects heterogeneity effects and seasonal effects. The results show that the factors influencing on the amount of rubber yields are spatial heterogeneity and seasonal effects. The proposed model is proper and forecast accurately. Using the mean absolute error (MAE) the proposed model has a better performance compared to the classical Holt-Winters Additive Exponential smoothing in both model fitting and model validating. The proposed model should be the first consideration for spatial time series forecasting.

Kansei engineering or effective engineering is an important product development methodology in which users’ or customers’ feelings and demands on the product are translated into important parameters for product design. On the other hand effective engineering is an application of users’ opinion mood and feelings in product design which seems to guarantee that the product will meet the demand of customers. This idea was first developed in early 1970s in Japan. Now it is widely used in both Asian countries such as Japan Korea Taiwan and European countries such as Sweden Spain and France. It is widely used in various fields like applied science and psychological science. This paper discusses the application of Kansei engineering in various daily-used products in both Japanese and Western lifestyles. The perspectives presented in this article are based on the authors’ engineering knowledge.

Purposes of the research were to design and develop Computer Assisted Instruction Package with tutorial through e-Iearning on computer technology curriculum and to find out efficiencies effectiveness and learners satisfaction towards the package. The research tools were: 1) The Computer Instruction Package on Database Management System SUbject 2) Achievement tests 3) Quality assessment and evaluation form for multimedia software and 4) questionnaire of learners satisfaction. Sampling groups composed of 50 Bachelor second year students from Faculty of Science and Technology Program Information Technology and Computer Rajamangala University of Technology Phra Nakhon. Research results revealed that the efficiency of the Computer Instruction Package was at 82.50/82.56 corresponding with 80/80 criteria. Analysis of pre-test and post-test scores found that the effectiveness after the process (Epost) was at 82.56 it was higher than before the process (Epre) which was at 14.62. Therefore the Computer Instruction Package on Program Design and Development could increase the students learning effectiveness up to 67.94 corresponding with 60 criteria. Mean of satisfaction of the sampling groups was rather at a high level (4.28). It could be concluded that the Computer Assisted Instruction Package with tutorial through e-Iearning on computer technology curriculum had the efficiency that could used for self study.
