This research aimed to study earning quality sustainability factors (ESG) and the relationship between earning quality and sustainability factors of the 59 companies listed in the sustainability index (SET THSI INDEX). The data was collected from the financial statements annual reports sustainability report and the data entry forms (Form 56-1) from 2015 to 2019. Descriptive statistics and inferential statistics were used in the data analysis including correlation analysis and multiple regression analysis The results of the study showed that most of the companies listed in the SET THSI Index had higher earning quality than the index average. The sustainability factor that has the greatest influence on earning quality is good governance. When the relationship between earning quality and sustainability factors (ESG) was analyzed it was found that there was a statistically significant correlation between environmental disclosures and good governance namely the number of the Board of Directors shareholding by Thai juristic person at the levels 0.01 and 0.05. There was a statistically significant opposite correlation between the disclosure of social responsibility information including anti-corruption aspect human rights aspect and responsibility to consumer aspect; and good governance including the proportion of shares held by family companies at levels 0.01 and 0.05.

The research objective is to study the relationship between environmental disclosure levels corporate governance and the performance of companies listed in the Real Estate and Construction group on the Stock Exchange of Thailand. It was conducted by collecting information from the financial statements the annual reports and the information registration forms (Form 56-1) of 91 companies from 2015 to 2019. Descriptive statistics and inferential statistics were used in data analysis including correlation analysis and multiple regression analysis. The study results showed that environmental disclosure levels including environmental policy disclosure and other environmental disclosures positively correlate with the rate of return on equity return on total assets with a statistical significance at 0.01 and 0.05 levels. Corporate governance including the percentage of shareholding by the management and the number of the Board of Directors positively correlates with the return on total assets with a statistical significance at 0.01 and 0.05 levels.

The purposes of this research are 1) to study the demographic characteristics and behavior in purchasing via line application and 2) to compare the level of satisfaction in purchasing via line application for an open chat consumer group Kheha Thanee 4 Village Bangkok. This study applied quantitative methods and the research instrument was an online questionnaire. The sample group of this study consisted of 306 consumers members of the open chat consumer group Kheha Thanee 4 Village Bangkok. The data were analyzed by frequency percentage mean standard deviation and the researcher tested hypothesis with T Test and One Way ANOVA. The research findings were as follows:

Purpose of this Using dried bananas to replace in Kanom Thong Muan the objective is to study the basic formula for Kanom Thong Muan in 3 formula and to study Using dried bananas to replace in Kanom Thong Muan were basic formula replace 20% 40% and60% By planning randomized complete block design (RCBD) and evaluating sensory quality in appearance (thin consistent) color odor taste texture (crumbly) and overall preference with the use of tasting methods for 9-Point Hedonic Scale. The study the basic formula for Kanom Thong Muan By allowing 40 tasters and the study this Using dried bananas to replace in Kanom Thong Muan By allowing 80 tasters to be undergraduates in foods and nutrition Faculty of Home Economics Technology Rajamangala University of Technology Phranakhon. Take average data (Mean) analyze variance (Analysis of Variance ANOVA) and compare different mean values (Duncan’s New Multiple Test DMRT) The results of the 3 basic formulas of Kanom Thong Muan namely formula 1 formula 2 formula 3 found that the tasting person accepted the formula 1 in appearance (thin consistent) color odor taste texture (crumbly) and overall preference. Average 8.20 7.90 7.85 8.05 8.30 and 8.15 respectively when analyzed Variance and comparison of differences found that appearance (thin consistent) color odor taste texture (crumbly) and overall preference There are significant differences at the level of 0.05. The results of the study of the amount of dried bananas that replaced sugar in 4 formula found that the tasting person accepted the formula replace 20% in appearance (thin consistent) color odor taste texture (crumbly) and overall preference average of 8.09 8.00 7.80 7.83 8.09 and 8.00 respectively when analyzed (3) Variance and comparison of statistical differences found that appearance (thin consistent) color odor taste texture (crumbly) and overall preference There are significant differences at the level of 0.05.

The purpose of this research was to study the dyeing polyamide/elastane fabric with natural indigo using exhaustion dyeing process. The effects from the concentration of the natural indigo dye thiourea dioxide and sodium hydroxide were investigated. The colour of each dyed material was investigated in term of the CIELAB (L* a* and b*) and K/S value. The color fastness to washing rubbing perspirdation light water sea water and chlorinated water of the dyed samples was determined. The bursting strengrh of dyed polyamide/elastane was evaluated. The best vatting condition was at 50 ̊C for 30 minutes. The optimal formula of dyeing polyamide/elastane fabric using natural indigo was prepared by mixing 200 g/L natural indigo paste 60 g/L thiourea dioxide 1 g/L sodium hydroxide. The fabric dyed in the solution of indigo vatting a shade of dark blue colour. The color fastness to light washing water sea water perspiration and chlorinated water were good to very good. However the rubbing fastness results showed fair level. The bursting strength of dyed fabrics is less than the undyed fabric 3.1%. The optimal ratio of discharge printing on polyamide/elastane fabric were compose of 70 % starch print paste and 30 % discharging agent (KMnO4). The pattern design produced from these combinations in the printing areas on fabrics showed an excellent standard of printing quality. The results confirmed that natural indigo dyes have potential applications in polyamide/elastane fabric dyeing and the dyed fabric can be used produce women’s intimate apparel.
