Thisr research used quantitative methods, namely by multiple linear regression, correlation coefficient and determination, and F test and t test. Based on the results of the research and discussion, some conclusions can be drawn as follows: From the quantitative calculations obtained using the multiple linear regression equation Y = a + b1X1 + b2X2 obtained Y = 3.808 + 0.238 X1 + 0.528 X2, namely the constant coefficient value (a) amounting to 3.808 this means that if the value of service quality (X1) and price (X2) equals zero, then the level or amount of customer satisfaction (Y) is equal to 3.808. The coefficient value of X1 = 0.238 means that if the service quality (X1) rises by one unit, while the price variable (X2) remains, customer satisfaction (Y) will increase by 0.238 and vice versa if the service quality (X1) decreases by one unit, while the price variable (X2) remains, consumer satisfaction (Y) will decrease by 0,238. The coefficient value of X2 = 0.528 explains that if the price (X2) rises by one unit, while the service quality variable (X1) remains, the level of customer satisfaction (Y) will increase by 0.528 and if the price (X2) falls by one unit, while the service quality variable (X1) remains that consumer satisfaction (Y) will decrease by 0.528. Multiple linear correlation coefficient (R) that is 0.885 means that the relationship that has a very high correlation between service quality and price to customer satisfaction is 0.885. The coefficient of determination (R2) is 0.783, meaning that customer satisfaction can be explained by variations in changes in the independent variable (service quality and price) of 78.3%, while the remaining 21.7% is explained by other variables outside the research. Based on the results of the F test, the calculated F value is 175,051 with a significant level of 0,000. While Ftable at 100% (0.05) is 3.09. In both calculations, F count> Ftable is 175,051> 3,09. This means that Ho is rejected and Ha is accepted, meaning that simultaneously service quality and price have a significant effect on customer satisfaction. Based on the results of the t test obtained the value of tcount X1> t table = 2.101> 1.98447 so that Ho is rejected and Ha is accepted, which means the independent variable (X1) service quality partially has a significant effect on the variable customer satisfaction (Y). Furthermore, the value of tcount X2> t table = 4.268> 1.98447 so that Ho is rejected and Ha is accepted, which means that the independent variable (X2) price partially has a significant effect on the variable customer satisfaction (Y).

Relationships between Islamic ethical behavior and Islamic factors among Muslim youths in the three southern border provinces of Thailand

This research investigated the relationships between Islamic ethical behavior and Islamic factors (Islamic way of upbringing, knowledge of the religion, participation in Islamic activities, and practicing Islamic principles) among Muslim youths in the three southern border provinces, Thailand. A cross-sectional study was conducted in which 2,160 Muslim youths were surveyed and relevant data collected. They were recruited using multi-stage sampling methods. The data were analyzed with the R program to calculate Pearson's product–moment correlation coefficients and multiple linear correlation coefficients. The study found that there were statistically significant correlations between Islamic ethical behavior and the Islamic way of upbringing, knowledge of the religion, participation in Islamic activities, and practicing Islamic principles (R2 = .474, p < .001). Practicing Islamic principles clearly had the strongest correlation in explaining Islamic ethical behavior (β = .42, p < .001). The Islamic way of upbringing, knowledge of the religion, and participation in Islamic activities also made some contribution in explaining the variance in the Islamic ethical behavior (β = .34, .17, and .09, respectively, all with p < .001).

Factors predicting domestic violence among Thai Muslim married couples in Pattani province

This study examined factors predicting domestic violence among Thai Muslim married couples in Pattani province and created a prediction equation for domestic violence. The data were collected from 1,536 subjects who were selected using multi stage sampling and data were analyzed using the R program to calculate Pearson's product moment correlation coefficients and multiple linear correlation coefficients. The results of the study revealed five predictors of domestic violence among Thai Muslim married couples in Pattani Province with predictability at a significance level of .001. Three predictors were found to have positive relationships with domestic violence: strict upbringing (X1), violent behavior in childhood (X6), and females' inferior status (X7) while severe punishment in childhood (X4) and the emphasis on male dominance (X8) had negative relationships with domestic violence and their prediction efficiency was 87.5 percent (R2 = 0.875, p < .001). Females' inferior status (X7) had the highest level of relationship, and severe punishment in childhood (X4) was the lowest.

Growth profile based crop yield models: A case study of large area wheat yield modelling and its extendibility using atmospheric corrected NOAA AVHRR data

Wheat growth profile based yield models for 12 districts of Punjab State and 16 districts of Haryana State have been developed using the normalised difference vegetation index (NDVI) derived from NOAA-11 AVHRR data of the 1993-94 cropping season. Atmospheric normalisation of AVHRR data was performed prior to deriving district-level area weighted average NDVI (AWANDVI). The invariant growth profile model suggested by Badhwar was fitted and spectral emergence date, maximum vegetative vigour, peak day value of profile, growth rate and senescence rate, area under the curve, etc. were derived. These parameters were related to the reported district-level wheat yields using multiple regression analysis. A field study was also conducted using a handheld spectro-radiometer at the research station of Punjab Agricultural University (PAU), Ludhiana. From this field experimental data, wheat growth profile parameters were derived which were compared with satellite based parameters. Inversion of the models was carried out to evaluate the results by comparing the reported and predicted wheat yields. The results indicate highly significant fitting of the NDVI profile to the Badhwar model as indicated by multiple linear correlation coefficients and Fisher test. A significant relationship between district-level wheat yields and fractional area under the curve was also observed. The overall correlation of 0.82 for Punjab and Haryana states was obtained between reported yield and growth profile derived parameters. Atmospheric normalisation resulted in improvement of prediction model statistics ( R increased from 0.42 to 0.86). Evaluation of the models indicated that 10 out of 16 districts of Haryana State and 9 out of 12 districts of Punjab State showed relative deviations within 10% between reported and model predicted wheat yields.

Work organization of heavy load handling in India.

The physical work rate, the energy and the cardiac costs of twenty-seven young male workers from the eastern part of India in five groups handling loads of about 30, 60, 75, 90, and 125 kg, respectively, were ascertained with the objective to rationalize the rate of work based on the physiological responses of the workers. The mean rate of usual work of the groups (I to V) was 4,715, 8,020, 7,350, 6,100, and 7,600 kg-m/min, respectively, which was considered to be extremely heavy. From the mean values of all the groups for the average work pulse rate of 143.1 beats/min, the recovery-pulse-sum of 119 beats for the first five minutes of recovery, the first and third minute recovery pulses of 127 and 114, respectively, the oxygen-pulse of 0.25 ml/pulse/kg, and the energy cost of 9.1 kcal/min, it was suggested that excepting the first group, the workers were working at a level much higher than the 50% level of their maximal working capacity. The simple and multiple linear correlation coefficients between the rate of work and the various physiological parameters were significant and different linear regression equations were suggested. In conclusion, for extremely heavy types of work in India, 1,200 kcal as the net optimal energy output in an 8-hr working day is suggested.
