This research aims to study attitudes quality of life and human relationships affecting the performance of professional nurses in large private hospitals in Bangkok. The sample group consisted of 400 professional nurses in large private hospitals in Bangkok. Data were collected using questionnaires. The statistics using were descriptive statistics like frequency percentage mean standard deviation and inferential statistics. The results showed that most respondents were female aged between 31 – 40 years with a bachelors degree and an average monthly income between 30001 - 40000 baht. The overall work attitude factor is at a very agreeable level. The mean value was 3.81. The overall Quality of life at work factor was at high level of agreement. The mean was 3.73 and overall human relations at work factor was at a high level ofagreement with an average of 3.88. Work attitude and human relations at work factors had a statistically significant effect on the performance of professional nurses in large private hospitals in Bangkok at the 0.05 level.

The research objective was to study social responsibility corporate governance mechanisms and audit quality that affect the operations of companies listed on the Stock Exchange of Thailand. The population used in this study was 76 companies listed on the Stock Exchange of Thailand. The annual financial data was from year 2016 to 2020. The data were analyzed using descriptive statistics such as mean standard deviation percentage and inferential statistics such as correlation analysis (Pearsons Correlation Coefficient) and Multiple Regression Analysis. The study found that the social responsibility on consumer responsibility (PRCI) was positively correlated with market share (MS). Environmental stewardship (EN) was positively correlated with Return on Assets (ROA) and company value (NVP). Innovative and outreach (CSRI) is negatively correlated with Return on Assets (ROA) and company value (NVP). Community or social development (CID) was negatively correlated with Return on Assets (ROA) and company value (NVP). Fair operation (SFOP) was negatively correlated with market share (MS). Anti-corruption (AC) was negatively correlated with market share (MS). Institutional investor shareholding (IS) was positively correlated with Return on Assets (ROA). Number of meetings (NBM) was negatively correlated with Return on Assets (ROA) and market share (MS). Institutional investor shareholding (IS) was negatively correlated with company value (NVP). Audit firm size (size) was positively correlated with Return on Assets (ROA) and company value (NVP) but negatively correlated with market share (MS). Compensation paid by auditors to LN clients (compensation) was positively correlated with company value (NVP).

This research aims to study how the level of excellence in the accounting profession and the usage of artificial intelligence technology affect the quality of financial reports of certified accounting practice. For the data collection the researcher used questionnaires. The population examined in this research consisted of 88 accountants working for high-quality accounting firms registered in Thailand. Descriptive statistics namely frequency percentage mean and standard deviation and inferential statistics including Pearson’s Correlation Coefficient and Multiple Regression Analysis were used to analyze the data. The study results reveal that accountants registered and working in high-quality accounting firms in Thailand reach a high degree of excellence overall. Furthermore artificial intelligence technology allows these accountants to positively affect the overall financial report quality at the highest level. The results of the research hypothesis test found that: 1) excellence in the accounting profession positively affects the quality of financial reports both overall and in every individual aspect and the result is statistically significant at the 0.01 level; 2) the use of artificial intelligence technology positively impacts the quality of financial reports both overall and in the individual aspect and the result is statistically significant at the 0.01 level.

This thesis presents improving power quality in power distribution system with integration of photovoltaic energy distributed generation having objectives to improve power quality in distribution system model of voltage sag and voltage swell in distribution system model of power loss in distribution system application of mathematical model model of power generation by using solar energy and distributed generation connection technique simulation. In this thesis the power flow was tested with Newton-Raphson algorithm joining with mathematical model. The case study was done by reduction of power loss in distribution system by using techniques of connection of distributed generation joining with model of distribution system 33 bus. The case study about improvement of voltage sag and voltage swell in distribution system used connection techniques of distributed generation joining with model of distribution system 69 bus. The study found that technique of connection of distributed generation that was presented could reduce power loss and showed the percentage of improvement of voltage sag and voltage swell in distribution system especially voltage sag case according to IEEE 1159-1995 standard. This thesis showed that severity level of voltage sag depended on the size and duration of each distribution system model situation by photovoltaic energy distributed generation can reduce voltage sag.

This research aimed to study the quality changes of coating salted eggs partially replacing soil from termite mound with turmeric powder at the level of 0% 5% 15% and 25% during storage for 4 weeks. The results showed that the increasing in turmeric level caused a decrease in salt content in raw egg yolk and raw egg white which led to decrease in hardening ratio of egg yolk. The hardness values of cooked - salted egg yolk decreased while those of cooked - salted egg white slightly increased. At the same salting period the color values of raw egg yolk and raw egg white coated with different levels of turmeric were slightly different. Egg yolks changed to a yellowish orange color while egg whites showed lightness with a direction of red and slightly yellowish color. The raw egg white coated with higher level of turmeric powder exhibited more yellowness which was in accordance with the increasing in curcumin content. From the results of 9-point hedonic scale in terms of color aroma overall taste and overall liking it was found that salted eggs coated with turmeric powder to partially replace soil at a level of 25% with 2 weeks of preserved duration had high scores of sensory acceptability which did not differ significantly from the control samples (0% turmeric) (p>0.05). The curcumin content analyzed in dry egg white was 3.885 mg/g at week 2 and increased to 13.291 and 18.484 mg/g at week 3 and 4 respectively.
