The objective of this study is to explore a method to improve UV protection and antibacterial properties of the cotton yarn surface to produce high-quality textile products. Cotton yarns were coated with sodium hydrogen phosphate magnesium chloride softener solution and 0 to 0.54 M of polyvinyl alcohol to hold surface yarns to the yarn body using the winding machine. The coated yarns were analyzed using Field emission scanning electron microscope Fourier transform infrared spectroscopy and UV-Vis spectrophotometer. Optimal results were achieved when coating with 0.45 M PVA exhibited UV protection was excellent protection. The cotton yarn coated 0.45 M polyvinyl alcohol displayed the antibacterial activity in the presence of Staphylococcus aureus and Escherichia coli was 87 and 91% respectively. The expected overall properties may open the way towards new applications of high performance fabrics leading to an innovative product development in the textile industry

This research was resulted of the characterization of cement paste composites (CPC) blended with palmyra fiber ash and surface-treated on short SWNT prepared by an electroless plating process. The cement paste composites included cement 270 meshes of palmyra fiber ash and short SWNT. The design of experiment was divided into 3 conditions namely uncuring 28 and 56 days in distilled water. The properties of CPC were carried out in chemical composition physical mechanical mineral phase microstructure and statistical analysis. It was found that in the chemical compositions an amount of silicon dioxide aluminium oxide and ferric oxide were 51.53% which was rated in class C. The bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) cured 56-day distilled water were an increased 38%. Then the highest specific electrical resistivity of CPC series PFA5OSWNT0.03 (F) cured 56-day distilled water was 1.14±0.31 mega-ohm.mm. The highest compressive strength of CPC series PFA5AgSWNT0.01 (G) cured at 28-day distilled water was 25.45±2.00 MPa compared with the OPC (A) was an increased 5%. Which the bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) were statistical analyzed the mostly cured at significant difference α = 0.05. In addition CPC series PFA5AgSWNT0.01 (G) mainly contained calcite portlandite quartz dolomite and ettringite were caused increasing compressive strength. And the SEM microphotograph were also displayed the calcium silicate hydrate portlandite and ettringite. Consequently the PFA was used to ability pozzolanic material using for lightweight concrete of CPC.

This research aims to produce activated carbon from molasses via a chemical activation process with potassium hydroxide (KOH) and a microwave heating process which consumes less energy and provides more rapid and uniform heat distribution than a conventional heating. The obtained activated carbon was then characterized with BET SEM and FTIR. It exhibited a large specific surface area of 1631 m2/g and a total pore volume of 1.124 cm3/g consisting of mesopore and micropore. In addition the active functional groups were also found on the surface of the activated carbon. Thus it was brought for the adsorption test with methylene blue. It was found that the adsorption capacity of the activated carbon increased with time and reached the equilibrium within 8 hours. The adsorption data of the activated carbon were corresponded to Langmuir isotherm with the highest adsorption capacity of 370.37 mg/g. The adsorption kinetic of the activated carbon exhibited pseudo-second order reaction suggesting to the chemisorption phenomenon. From the thermodynamic study it revealed that the adsorption process were endothermic and spontaneous reactions.

This study purpose was to investigate the changes affecting the working behavior of non-profit organization personnel. The population used in this study was 64106 non-profit organization personnel: Foundations and associations. The data was collected using a questionnaire from 203 non-profit organization personnel. Statistical multiple regression analysis was used to test the study hypothesis. The study results revealed that there is a correlation between organizational changes including the attitude change change in corporate culture technology change and changes in organizational structure and the working behavior of the personnel of the non-profit organization as a whole including the aspect of helping others consideration for others patience sense of duty and cooperation with the statistical significance at 0.01 level.

This research aimed to study the relationship between Corporate Governance Social Responsibility and Profitability of 56 companies related to the agriculture and food industry and listed on the Stock Exchange of Thailand. Data was collected for 2015 to 2020 and analyzed using descriptive statistics such as frequency percentage mean and standard deviation. Likewise this research also used inferential statistics including Pearson’s Correlation Analysis and Multiple Regression Analysis. The findings were Corporate Governance; Proportion of Independent Director (PID) had positively correlated with Profitability including the Return on Total Assets (ROA) the Return on Equity (ROE) and the Gross Profit Margin (GPM). The correlations were statistically significant at 0.01 and 0.05 levels. Besides Corporate Social Responsibility; the Environmental Social and Governance (ESG) and the Disclosure of Corporate Social Responsibility Activity (DCSRA) had also positively correlated with Profitability including the Return on Total Assets (ROA) the Return on Equity (ROE) and the Gross Profit Margin (GPM). The correlations were statistically significant at 0.01 and 0.05 levels.
