The research objectives were to study the correlation between the social information disclosure and the performance and the impact of corporate governance on the correlation between the social information disclosure and the performance of companies listed on The Stock Exchange of Thailand SET100 group. The information was collected from the notes to the financial statements annual registration statements (Form 56-1) and annual reports from 2016 to 2020 of 68 companies. Data were analyzed by using descriptive statistics such as mean standard deviation percentage and inferences statistics include Multiple Regression Analysis. The study results found that the social information disclosure on consumer responsibility is in line with Return on Equity (ROE). The disclosure on innovation and innovation dissemination from social responsibility practices correlates in the negative direction to Return on Equity (ROE). In addition the disclosure on anti-corruption was inversely related to Return on Assets (ROA). On the impact of corporate governance on the size of the Board of Directors and the shareholding proportion of the major shareholders there is a negative correlation between social information disclosure on anti-corruption and Rate of Return on Assets (ROA). There is a negative correlation between the proportion of independent directors and social information disclosure on innovation and innovation dissemination from social responsibility practices and Return on Assets (ROA). There is a positive correlation between the percentage of shares held by management and directors and social information disclosure on coporate governance and environmental management and Return on Assets (ROA). There is a negative correlation between the percentage of shares held by management and directors & the position merging of Managing Director and Chairman of the Board and social information disclosure on human right records and Return on Assets (ROA). There is a positive correlation between the merging of the Managing Director & Chairman of the Board and social information disclosure on consumer responsibility and Return on Assets (ROA). There is a positive correlation between size of the board of directors & the shareholding proportion of the major shareholders and social information disclosure on human right records and Rate of Return on Equity (ROE). There is a positive correlation between size of the board of directors the proportion of independent directors shareholding percentage of major shareholders and the position merging of Managing Director and Chairman of the Board and social information disclosure on consumer responsibility and Rate of Return on Equity (ROE). There is a negative correlation between size of the board of directors the proportion of independent directors and the shareholding proportion of the major shareholders and social information disclosure on innovation and innovation dissemination from social responsibility practices and Rate of Return on Equity (ROE). There is a negative correlation between shareholding proportion of executives & directors and social information disclosure on human right records and innovation and innovation dissemination from social responsibility practices and Rate of Return on Equity (ROE). There is a positive correlation between and the merging of the Managing Director & Chairman of the Board and social information disclosure of fair treatment of workers and Return on Equity (ROE).

This thesis was an analysis of the significance of angle of inclination and the thickness of the armor plate on the penetration resistance of bullets on aluminum and stainless steel armor plates determined by the finite element method. In this study the information results obtained from actual firing of bulletproof armor and the finite element simulation according to NIJ 3 standards were compared to create a pattern of bulletproof and bulletproof armor using the SolidWorks program. The simulation model of the armor shooting was created by the Ansys/Explicit Dynamics program. The bullet material was 7.62 mm tungsten carbide (WC). There were three plate types used in the simulation were made of different bulletproof armor materials: 1) stainless steel SUS304 using for the plate thickness of 5 6 8 10 14 20 30 40 45 and 55 mm. 2) aluminum AL7075 using for the plate thicknesses of 6 8 10 and 20 mm. Additionally 3) tungsten carbide using for the plate thicknesses of 6 8 and 10 mm. Each of these plates had a width x length of 300 x 300 mm. The simulation models were divided into two types: Type 1 a simulation firing at one plate at a time. Type II a simulation firing at two layered plates stacked together without any gaps between plates. The front and the back plates made of stainless steel and aluminum respectively or tungsten carbide and stainless steel respectively were determined. The angles of firing at bulletproof armor were set at 0 30 and 45 degrees. The output results were that in Type I the stainless-steel plate with a thickness of 30 mm or more could resist the penetration of bullets. However in Type II 2 stacked layers of the armor plates using the front stainless plate with a thickness of only 20 mm and the back aluminum plate with a thickness of only 8 mm could provide the same constructive results as those of tungsten carbide and stainless steel plates for the front and back plates with both thickness setting at 16 mm. All of them showed the resistance of the penetration to the bullets. More observation was that the increases in angles as a result enhanced more resistance of the bulletproof plates to bullet penetration.

This research article aimed to investigate the Gharavasa-dhamma IV which appeared in the royal guidance of His Majesty King Bhumibol Adulyadej the Great. The sample was The Royal Guidance of His Majesty King Bhumibol Adulyadej the Great about religion and morality book of the Department of Religious Affairs (Ministry of Culture 2009). Gharavasa-dhamma IV principle in Buddhism which was defined in Dictionary of Buddhism by Phra Bhramagunabhorn (P.A. Payutto) (2015) was the conceptual analysis framework. The study is based on the documentary research and presented through analytical description. The study found that the royal guidance of His Majesty King Bhumibol Adulyadej the Great can be classified into 3 groups: civil servant youth and Buddhist association with the young Buddhists association. according to the royal guidance literally conformed Gharavasa-dhamma IV was found a total of 21 words of Sacca [truth and honest] 22 words of Dama [taming and training oneself] 15 words of Khanti [tolerance ; forbearance] and 21 words of Caga [generosity]. However in some Royal Guidance there were more than one characteristic as well of Gharavasa-dhamma IV. The royal Guidance therefore has aimed on people to know how to be a good citizen in society for the benefit of People in nation and for their happiness.

This research aimed to study the optimum factors affecting the quality of gold plating process to enhance OTOP knife products of Ban Mai knife forgers village. This study focused on application of AISI 5160 steel and the 24k gold plating process.In the experiment three samples of plating currents were observed; 10 12 and 14 volts each at 30 60 90 120 150 seconds and 180 seconds respectively. The study found that applying the electric currents in gold plating at 12 volts for 120 seconds gave the best results for the gold color and thickness by giving the thickness of the gold surface at 33.82 micron and the color value between L*=88.72 a*=4.45 and b*=78.58. Moreover the gold dispersion was consistent throughout the workpiece. From applying the electric currents in gold plating at 10 volts it lessened the thickness of the gold plating which made the gold plating look uneven. From applying the electric currents in gold plating at 14 volts it increased the thickness of the gold plating which resulted in a dull or burned finish from over-plating. In comparison the cost of the knife before plating with gold costs only 30 baht per piece while the cost of the knife after plating with gold costs 99 baht per piece. In conclusion the daily sales of a product increase from 50-60 items per day to 60-75 items per day which also resulted in increased revenue and profitability from 1500-1800 baht per day to 5940-7425 baht per day on average.
