The objective of this research is to select a proper cumulative function for trend in an analysis of simultaneous multiple time series data with autocorrelation trend and outliers using a Bayesian method. The proposed model is applied to fluctuate stock price data in the stock exchange of Thailand. The data consist of the closing prices of 5 stocks. The algorithms are written in OpenBUGS and the performance of the model is evaluated via a simulation study in R. The cumulative distribution functions considered here are a Weibull cumulative distribution function and an exponential cumulative distribution. They are compared using RMSE MAPE and MAE as criteria. The research found that an exponential cumulative function for trends gives smaller values of the three criteria in both model fitting and model validation for the4 stocks EA NWR and KTB. However a Weibull cumulative distribution function gives smaller values of three criteria for the PTT in both model fitting and model validation.

The study aimed to investigate and compare the back-pain level peak-to-peak voltage and period time of Electromyography (EMG). The sample of this study was 31 patients of Yasothon Hospital. The instrument consisted of an electrocardiography (EKG monitor). For statistical analysis t-test and f-test were employed. The findings revealed that mean is The Back-Pain level of most patients was 2 (35.5 %). The peak-to-peak voltage of Back-Pain levels (1-5) were 0.11 0.12 0.21 0.25 and 0.20 mV. While period time of Back-Pain levels (1-5) were 0.85 0.86 0.86 0.62 and 0.68 s. respectively. The peak-to-peak voltage of Back-Pain levels (1 and 2) were different levels (3 and 4) at .05 level of significant. In addition the period time of Back-Pain level (4) was different levels (1 2 and 3) at .05 level of significant

The relativity of the Downy Mildew (45 and 60 days after transplanting) for 109 lines in both yield and yield components of cucumber from July 2012 to March 2013 was studied at Agricultural Technology Research Institute of Rajamangala University of Technology Lanna Lampang. It is discovered that the correlation coefficient of downy mildew levels at 45 and 60 days after transplanting correlated well at 0.78 (r = 0.73). Furthermore it is also found out that the correlation coefficient of downy mildew levels at 60 days after transplanting was negatively correlated with fresh yield per rai at 0.58 (r = -0.58). When considering from the path coefficient it is found that the number of fruits per plant had high total effects and direct influence on yields per rai (0.84 and 0.70 respectively). Whereas the downy mildew levels at 60 days after transplanting had negative total effects at -0.58 indirectly with number of fruits per plant at -0.27. Thus the cucumber with high downy mildew at 60 days after transplanting will lead to 58 percent of yield reduction that it will reduce the number of fruits per plant which caused yields reduction.

The objectives of this research were to find the correlation between the milling degree and the milling quality of rice which was the basic data to investigate the milling degree equipment. Chainat 1 and KDML 105 rice varieties were milled at difference degree of milling (DOM) which calculated from bran removed. The study revealed that as the DOM increase the milled rice and head rice decreases. Therefore the whiteness transparency and milling degree of milled rice which was measured from Milling Meter also increased. When the DOM increased the whiteness transparency and milling degree also increased. The DOM had highly correlation not only to milled rice and bran but also to milling degree from Milling Meter at R2=0.99 and R2=0.97. So these correlations could be used to investigate the milling degree equipment.

The purposes of this research were to study the canonical relationship between some factors and motivation on producing that relative contribute to academic papers and to study the canonical weights of some factory motivation on producing academic papers. The Sample were the 222 instructors in the office Rajamangala University of technology Phra Nakhon who work during the first semester of Academic year 2005. The stratified random sampling technique was used for selecting the sample. The instruments were the questionnaire considering the salary work load working experience Attitudes toward producing academic papers Self development Internal control Academic ability Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers. The findings were as follow: 1. The canonical correlation between Salary Work load Working experience Attitudes toward producing academic papers Self development Internal control Academic ability Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers were .510 .231 and .134 respectively. The first canonical function was Statistically Significant at .05 level. The second and third canonical function were Statistically nonsignificant. 2. The canonical weights for Attitudes toward producing academic papersself development and Internal Control relative contributed to Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers in the first canonical function.
