การประยุกต์การใช้พลังงานแบบผสมผสานเพื่อบูรณาการกับภาคการเกษตรกรรม
The application of integrated energy use in the agriculture sector It is presented in the form of using renewable energy from solar energy to produce electricity to use in conjunction with other sources of electricity such as generators or electric power systems. Using solar panels or solar cells the size and number of panels does not exceed 300 watts 4 panels and the electrical system of the electrical system. Supply electric power to the water pump size does not exceed the rating of 1500 watts 220 volts. Solar power supply systems alone may be affected by weather conditions or electrical power supplies. Including the quality of electricity obtained from solar energy and will result in the water pump not working efficiently. Therefore the application of solar energy by using a power supply system from 2 sources by using a hybrid inverter device to select the power supply from the solar cell is the main power and the power supply from the memory system is the backup power. Therefore a research project on the application of solar water pumps in a mixed system for agriculture is proposed to increase the efficiency of electric power distribution. This application of solar water pump hybrid system for agriculture when used with water pumps can normally help to save electricity and can also use solar energy instead of using electricity to pump water. Let the water pump and can work efficiently.

The objective of this research is to study the techniques of profit quality analysis and the consistency of the profit quality with different profit quality analysis techniques; and to compare profit sustainability between large companies and small companies of the industrial energy and utilities group and the petrochemical and chemical group. The data is collected from financial statements and data entry forms (Form 56-1) from 2012 to 2018. A total of 47 companies are analyzed using descriptive statistics including mean and standard deviation; and inferential statistics including multiple regression analysis and analysis of the average difference between 2 groups The research found that in the analysis of the profit quality consistency in all 4 methods there were only 13 companies in the energy and utilities group with consistent quality of profits accounting for 39.39%; and 20 with inconsistent results accounting for 60.61%. In the petrochemical and chemical group there was only 1 company with consistent quality in all 4 methods representing 7.14%; and 13 companies with inconsistent quality representing 92.86%. In addition when comparing the profit sustainability between large companies and small companies it was found that there was no statistical difference in profit sustainability (sig = 0.305> 0.05). When comparing the profit sustainability between energy and utilities group and the petrochemical and chemical group it was found that petrochemical and chemical companies had a higher profit sustainability than the energy and utilities group at statistical significance of 0.01 (sig = 0.009 <0.01).

The purposes of this research were to analyze arts and sciences educational management circumstance in general education course of higher education. Including study arts and sciences educational management in general education course in the 21st century. They were mixed method research. The data were analyzed by descriptive statistics and content analysis. It was found that the current circumstance of arts and sciences educational management in general education course of higher education found 3 parts; (1) the teaching process in general education courses focused on relationship skills knowledge cognitive skills and the numerical analysis teaching (2) responsive subjects in teaching methods the instructor focused on instruction emphasizing on the combination approach teaching used practice and research teaching (3) teaching activities the instructor emphasized in classroom activities rather than outside classroom activities. The approach of arts and science educational management in general education courses corresponds to learning in the 21st century found that focus on living and working with teaching process in the moral and ethics the knowledge cognitive skills relationship skills and the numerical analysis. The cognitive skills and innovation should focus on the teaching of moral and ethics and the knowledge and IT skills media and technology should focus on moral and ethics teaching the knowledge and cognitive skills.

The potential health benefits attributed to mulberry leaf and its bioactive compounds have led to a huge increase of mulberry leaf products in the food market. The objective of this research was to determine total antioxidant activities ( FRAP and DPPH assays) and polyphenol compounds in 4 snack products i.e. loaf-bread puifai (Thai steamed cupcakes) peakpoon (Green coconut sweet pudding) and snow skin mooncake fortified with 10% mulberry leaf powder from “ Buri Rum 60” cultivar. The result showed that antioxidant activities and polyphenol contents increased in 4 products fortified with mulberry leaf powder. Ferulic acid was the only phenolic compound found in all original products. Kaempferol quercetin and caffeic acid were significantly increased whereas ferulic acid was reduced in the modified formulas. Therefore these bioactive compounds properties of mulberry leaf powder suggested their possible use for fortifying the healthy foods.
