The replacement of partial sugar with jaggery palm in Khanom Ar-Lua production was further carried out for studying the suitable ratio of jaggery and sugar are 25:50 50:50 and 75:25 and studying the suitable drying time which varied period of time at 8 9 10 and 11 hours. Analyze nutritional values of Khanom Ar-Lua that sugar partially replaced with jaggery palm and Randomized Complete Block Design (RCBD) was applied. Sensory evaluation (color flavor taste texture and overall liking) was tasted by sixty panels with 9-point hedonic scale. After that using 5-point hedonic scale for consumer acceptance test by one-hundred panels. The results showed that Khanom Ar-Lua which use of jaggery palm replacement partial sugar at ratio of 25:75 had the highest score in every properties of sensory test. The suitable drying time is 10 hours. Khanom Ar-Lua that used jaggery palm to replace partial sugar had higher protein carbohydrate and total energy than basic recipe but moisture content and energy from fat are the lower. The consumer acceptance test showed that 99% acceped Khanom Ar-Lua which using jaggery palm replaced patial sugar.

The objectives of this research were 1) to study attitude and advertising media exposure of the BTS passengers; 2) to compare the relationship between the BTS passengers’ demographic characteristics and their service behaviors; 3) to compare the differences of the BTS passengers’ demographic characteristics towards their advertising media exposure; and 4) to study the relationship of the passengers’ attitudes on the BTS in-trained advertisement with the BTS passengers’ advertising media exposure. The researcher randomly selected 400 participants through the Cluster sampling method by using the questionnaire as a data collection tool. The analytical statistics included standard deviation mean average and frequency distribution. The hypothesis testing included Chi-square T-Test F-Test (ANOVA) values testing and Pearson Prodcut Moment correlation coefficient.

The objectives of this research are to propose a proper model for risk assessment for drought in Thailand. A hidden Markov model is adopted. The results indicate that the amount of rainfall depends on the hidden states drought or non-drought state. If the state changes from drought to non-drought the amount of rain will increase. The probability of changing from drought state to non-drought state is higher than from drought state to drought state. The probability of drought occurrence in February is highest followed by in November March December January July April June October September August and May respectively. When the temperature increases the probability of drought occurrence will increase.

This research presents an Analysis of Voltage Sags on the Installation of Distributed Generation in the Distribution System. The computer program PSCAD/EMTDC (Power Systems Computer Aided Design / Electromagnetic Transient in DC system) version 4.2 is applied to provide electrical parameters for the modeling and simulation and to analyze the fault occurred which resulted in voltage sag. Test results from PSCAD/EMTDC show the values of voltage sag when 5 types of fault are occurred (Single Line to Ground Fault Double Line to Ground Fault Three Phase to Ground Fault Line to Line Fault and Three Phase Fault). For all cases the value of root mean square voltage before fault is 100% or 1.0 pu. It can be seen that for both radial line and closed circuit when DG are installed in the system the value of phase to ground RMS residual voltage and phase to phase RMS residual voltage at the bus of Bang-pa-in 2 substation are more than the values in case of the system without DG.

The purpose of this research was to investigate the factors affecting internet usage of the general public in Linthin Thong Pha Phum District Kanchanaburi province. Analyzes of opinions on factors affecting internet usage. When classified according to the social characteristics and norms of Internet users. Personal factors Motivation and ability of the person to exchange knowledge. Confidence factors system security privacy and the benefits of using. It was found that the opinions on satisfaction were at the high level. And when the value of the entertainment. The opinions on satisfaction were at the highest level.
