The results indicated that 1) Most of people in muo-baan Suan-Son community had low bachelor degree enough income each month satisfied with family over work and community considered that the environmental protection in the community was moderate and the environment in the community was middle clean and enough. 2) The component of factor influence to quality of life of people in Muo-Baan Suan–Son community had health treat family community and welfair.

The objective of this study was to investigate the optimal formulation of mulberry fruit leather product when varying the weight ratio of mulberry fruit: water as 70:30 60:4050:50 40:60 and 30:70. Three factors were then determined by simplex centroid design; sugar (0-100% or 0-50 grams) citric acid (0-100% or 0-5 grams) and pectin (0-100% or 0-3 grams) which the sum of them equivalent to 100% while other ingredients remained constant. Analysis of the data was performed using ANOVA and Mixture Response Surface Models. The results indicated that the highest adhesiveness force and gumminess of mulberry fruit leather product were founded when the weight ratio of mulberry fruit to water was 70:30. The amount of sugar acid and pectin had effects on water activity (Aw) texture profile and sensory score of overall liking of product. From contour plot the predictive models were obtained by plottin g the contour line of all sensory attributes with acceptable score greater than 5.5 and thus the optimization area was selected. After overlapping contour plots an optimal formulation obtained was composed of 40-70% sugar 0-5% citric acid and 30-55% pectin. The sensory score of overall liking of product using a 9-point hedonic scale was 6.3. The water activity (Aw)adhesiveness force cohesiveness and gumminess of the prototype mulberry fruit leather product was 4.9 945.11 g. sec. 0.85 N and 452.12 N. respectively.

The objectives of this research is for study of Quality Control in accordance with Quality Control Standard No.1 (TSQC1) and Audit Quality test the difference of Quality Control in accordance with Quality Control Standard No.1 (TSQC1) and Audit Quality test the relationship and positive impact of quality control of audit firm in accordance with Quality Control Standard No.1 (TSQC1) with Overview Audit Quality of Big 4 and Non-Big 4 Auditing Firms. This research is done by give out questionnaires and in-depth interviews method which used populations of 228 auditors certified by the Securities and Exchange Commission in Thailand by receiving 115 replied questionnaires which considered as 50 percent and using Descriptive Statistics T-test Statistics Pearson’s Correlation Coefficient and Stepwise Multiple Regression Analysis The results say that Quality Control in accordance with Quality Control Standard No.1 (TSQC1) in overview and individual element of Big 4 and Non-Big 4 Auditing Firms completely applied. Big 4 Auditing Firms have higher average than Non-Big 4 Auditing Firms highest average is for ethical requirement. Audit Quality both in overview and individual element Big 4 and Non-Big 4 Auditing Firms completely applied. Big 4 Auditing Firms have higher average than Non-Big 4 Auditing Firms highest average is for clearness. From test hypothesis of quality control of auditing firm in accordance with Quality Control Standard No.1 (TSQC1) of Big 4 and Non-Big 4 Auditing Firms is according to assumptions by having differences in all elements while Audit Quality is according to assumptions only one element which is clearness no difference in statistical significant. Quality Control in accordance with Quality Control Standard No.1 (TSQC1) has relationship and positive impact with Audit Quality and from prediction equation find that enhance of audit quality of auditing firm should emphasize to Quality Control in accordance with Quality Control Standard No.1 (TSQC1) in engagement performance and ethical requirement.

This Thesis presents an analysis of wind turbines in a power distribution system that has a wind power source. By comparing the wind turbine with 3 blades and 4 wind turbines while there is no distribution in the distribution system. And the load is distributed in the distribution system To analyze the differences of these 2 wind turbines analyze the pressure values The power quality in the distribution system that occurs. And able to apply wind turbine energy for sustainability And practices to support the correct power supply In the distribution system and able to provide electricity with efficiency and reliability Wind turbine when connecting to the electricity distribution system There is a significant impact on the power distribution system such as the impact on the power loss. Pressure impact etc. It can be seen that the wind turbine with 3 blades works less than the wind turbine with 4 blades not so much. Therefore the test shows that the analysis of the electricity quality in this distribution system for use as a case study And continue to improve the production of wind turbines in the electricity distribution system.

The purpose of this study was to investigate the perceived service quality of QC Car Audio users and compare the quality of service provided by QC Car Audio stores classified by their demographic characteristics. The sample was 267 customers using the QC Car Audio service from January 2015 to January 2017. The statistics used for the data analysis included frequency percentage mean standard deviation and t-test was applied as well as the analysis of one-way ANOVA. The study found that the overall quality of QC Car Audio service provided by the customers was at the highest level. It was also found that the customers’ different gender age marital status education monthly income occupation and service location did not significantly vary in terms of the service quality perception towards QC Car Audio in the overall. When looking into each five aspects there were no significant differences. However different service locations yielded different service quality perception towards QC Car Audio at the .05 statistically significant.
