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.

This study was aimed to 1) explore opinions on organizational culture 2) compare job satisfaction 3) compare the influence of organizational culture on job satisfaction of support personnel at Rajamangala University of Technology Phra Nakhon. This is quantitative research which its sample was 209 support staff at Rajamangala University of Technology Phra Nakhon obtained through proportional stratified random sampling. The data were collected by questionnaire and analyzed by frequency percentage mean standard deviation t-test F-test and Pearson product moment correlation coefficient. The research revealed as follows. 1 ) Rajamangala University of Technology Phra Nakhon support staffs highly demonstrated opinions on organizational culture and were highly satisfied with their work. 2 ) Rajamangala University of Technology Phra Nakhon support staffs’ work satisfaction with different genders and salary base levels were 0.05 statically different. 3) The satisfaction of Rajamangala University of Technology Phra Nakhon support staffs were 0.05 statically satisfied with 1) success aspect 2) personal aspect 3) self - actualization aspect had the overall satisfaction at the 0.05 level of significance. As for the organizational culture related to affiliation did not influence the satisfaction of the support personnel at Rajamangala University of Technology Phra Nakhon.

In this work the objective is to develop the bilayer structure consisting of hydroxyapatite-alumina (HAp-Al2O3) layer and 3 mol% yttria tetragonal zirconia (TZ-3Y) layer using conventional technique consisting of the simple pressing together with pressureless sintering. In order to obtain the desired characteristics of bilayer structure layer thickness cosintering temperature and Al2O3 addition on successful fabrication of HAp-Al2O3/TZ-3Y bilayer structure are investigated. The results indicated that the HAp-10A/TZ-3Y bilayer structure was successfully fabricated by single-end die pressing the powders in hollow cylindrical graphite die under 60 MPa pressure and further wet-bag isostatically pressing in oil to 300 MPa pressure before sintering at 1200 ˚C for 1 h. It is found that an addition of 10 vol% Al2O3 into the HAp outerlayer is the essential condition to effectively suppress the differences in densification and coefficient of thermal expansion of the two layers during cosintering at 1200 oC for 1 h. The obtained HAp-10A/TZ-3Y bilayered disc has diameter of 21.0 mm HAp-10A outerlayer of 4.5 mm thick and TZ-3Y underlayer of 2.5 mm thick. The XRD pattern of the powders crushed from its HAp-10A outerlayer revealed no transformation into other new phases demonstrating that there is no reaction between HAp and Al2O3 during sintering at 1200˚C. The cross-section morphology of HAp-10A/TZ-3Y bilayered composite obtained from the SEM result revealed the porous structure with good interconnectivity. The high porous structure of the bilayered composite provided high surface area for cell attachment indicative of good cell growth and differentiation. The primary grain sizes of HAp-10A outerlayer and TZ-3Y underlayer were in the range of 1-3 um and 100-500 nm respectively. The hardness of HAp-10A layer and /TZ-3Y layer in bilayer structure varied with different layer thicknesses. Accordingly the results presented in this work demonstrated that the HAp-10A/TZ–3Y bilayered composite fabricated by simple technique has thick HAp-Al2O3 outerlayer and strong interfacial bonding between interface layers which can be tailored for specific applications

The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.

This study was aimed to 1) to compare the brand value perception of Rajamangala University of Technology Phra Nakhon and 2) to study the influence of marketing mix on the brand value perception of Rajamangala University of Technology Phra Nakhon. This research is quantitative research which included the samples of 400 undergraduate students from the first to the fourth year selected through proportional stratified random sampling methodology. The collected data were analyzed by frequency percentage mean standard deviation and the hypothesis was tested by the Independent sample t-test. One-way ANOVA was applied and Scheffes Pearsons Product Moment Correlation Coefficient and stepwise multiple regression analysis were used to look into mean difference in pairs. The results of the research on the brand value perception of Rajamangala University of Technology Phra Nakhon revealed that the students who were different in terms of age group faculty and study year perceived the brand value differently and significantly at the 0.05 level of significance. The marketing mix factors including 1) the available curriculum 2) the teaching and studying location 3) educational support 4) academic and support staff 5) physical environment and 6) teaching and learning management influenced the brand value perception of Rajamangala University of Technology Phra Nakhon at the 0.05 level of significance. As for the marketing mix factor and cost of education did not have the influence on brand value perception of Rajamangala University of Technology Phra Nakhon.
