The population studied is 308 successful enterprises that received the Outstanding Corporate Governance Award from the Department of Business Development at the national and provincial levels from 2016 – 2018. The sample group is 179 entrepreneurs and enterprise employees using questionnaires as a tool for data collection. The statistics used for data analysis are percentage mean standard deviation correlation analysis and multiple regression analysis. The research results showed that good governance participation and cost effectiveness had a positive relationship with the overall enterprise performance. The moral principles had a negative relationship with the enterprise performance as a whole with statistical significance at the level of 0.01. The efficiency of waste reduction had a positive relationship with the overall business performance of the enterprise with statistical significance at the level of 0.01. The good governance accountability and efficiency in reducing waste are positively correlated with overall performance with statistical significance at the level of 0.05 and with the statistical significance at the level of 0.01 respectively

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.

This is an independent study on greenhouse gas emissions and ways to reduce them. A five-star resort in Koh Samui Surat Thani province has been used as a case study. The study used digital tools to gather information on activities that cause greenhouse gases and energy consumption at the resort. The calculation of carbon footprint is in line with the guidelines of the Thailand Greenhouse Gas Management Organization. Digital systems help data collection and carbon footprint analysis and this is best done at set intervals. For example digital systems can monitor power consumption every 15 minutes measured in real time. The carbon footprint maximum emission each day occurs between 2.00 and 4.00 pm the peak time of energy consumption. Use of electricity is the activity that produces the highest amount of greenhouse gases at a total volume of 4215.1 tonCO2-e per year or 88.12% of the total activity. LPG gas consumption produces the second largest volume of greenhouse gas emissions at 412.8 tonCO2-e per year or 8.63% of the total activity. From January to December 2017 the carbon footprint emission is 4783.5 tonCO2-e and the average emission per room night is 4.2 tonCO2-e. The study found that a 10% reduction in energy Consumption could reduce greenhouse gas emissions by 421.52 tonCO2-e per year or 0.4 tonCO2-e per room night.

This research aims to 1) study marketing strategies that related to decision making while they purchase for SME Thai Herbal Skincare Product in Bangkok Metropolitan 2) study factors relevant to marketing strategy for consumer decision making while purchase for SME Thai Herbal Skincare Product in Bangkok Metropolitan 3) analyze marketing strategies that related to consumer decision making while they purchase for SME Thai Herbal Skincare Product in Bangkok Metropolitan. Samples were randomized from 57635.18 population in Bangkok calculated followed Krejcie and Morgan statistics table with its 381 samplings were drawn purposively. This research is using survey technique and its instrument using questionnaire for data collecting. The analysis of data using frequency percent mean standard deviation and relation analytical were under canonical correlation. The results were religious group are mostly adopted herbal skincare product and has related to marketing strategies and service marketing strategies in term of the need to enhance in knowledge of herbal skincare product. Also as the need of original herbal skincare product brand name but in the modern style and product guarantee are related to repurchasing and consumer loyalty with high correlation.

The tungsten carbide powder which recycled from the scarps of cemented tungsten carbide produces the purity of 99%. Using this tungsten carbide powder to manufacture a cutting tool and test its properties are the main objective of this work. Based on the standard SNMG 120408 the cutting tool with the dimension of 12.7x12.7x4.76 is fabricated. With the 100 hours of Ball milling grinding Cobalt mixing and sintering at 1430 °C the experimental result is impressive. At 15% of mixedcobalt the cutting tool with the hardness of 2031.6 HV be able to cut S45C steel in the feed rate of 0.2 meters per revolution and 45 m/min in the cutting speed. Besides that it provides the depth of cut of 0.25 mm and when it reaches the cutting distance of 4200 mm the surface roughness is 3.65 μm. In comparison with the cutting tool made of imported tungsten carbide powder which has a hardness of 1254 HV it turned out that our cutting tool has the equivalent quality in terms of hardness and wear resistance. Hence this work is considered to be a material development and a tungsten carbide cutting tool manufacture those would be the vital base to lead us to a commercial production.
