Most of the current containers that we put food are made of plastic or foam boxes. After the use is finished the container becomes rubbish and will greatly affect the environment. Due to slow degradation Plus informal disposal And higher consumption The use of natural products is in great demand. Because it is beautiful and natural-looking pleasing to consumers Therefore the basic processes forming patterns were studied by rubber product molding techniques. Determine the material to be molded into the sample container. Design and build a small molding set. Provide binders used for the stabilization of natural materials. Experiment for forming and the Conclusion of the experiment From the results of operations and experiments it was found that the study of the prototype extrusion set Using a rubber molding technique Can be applied by various elements The process of rubber molding can be used in the development of natural container molding and the process can produce prototype containers from natural materials. Under the suitable size of the mold the area of the mold is smaller than the mold plate area of the machine or the size of the mold area the area of no more than 60-70% of the mold holder plate.

The objective of this research is to study the development of eco cars using power-cutting mechanism technique of Transmission System. Two eco cars had been studied. The first car was conducted with the aim of developing transmission system and clutch system by changing from gear drive transmission system and chain drive mechanical clutch to belt and pulley transmission system by new designing the belt and pulley transmission system to have propeller shaft as the device to transmit power from the right to the left side with bearings to help reduce friction. Pulley system and clutch lever were installed in which the newly built clutch can be controlled by driver. The new model of transmission system is weight 0.7 kg which is lighter than the previous weight of 0.8 kg. Based on the first testing by participating in the 22nd Honda Eco Mileage Challenge at Chang International Circuit it was found that the system with belt tension at 1 kN resulted in good performance of transmission system and clutch system with fuel efficiency value at 626.157 km/L. After that the belt tension was adjusted and set up at 1.1 kN for 3 tests at Solar Track Thailand and it was found that the maximum fuel efficiency value was 1061.18 km/L at the speed of 34 km/hr. The second car was improved in transmission system suspension system steering system and also engine. The first trial was experimented on the 22nd racing event at the Chang International Circuit where this fuel efficient prototype car could run at 18 km. The result showed that it could have good mileage which was 275 km/L. After improvement the car was tested again for three times at the Solar Track Thailand circuit where it ran at 16 kilometers. The result revealed that the best saving was equivalent to 613 km/L at the speed of 30.6 km/hr.

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 objectives of The Prototype of Mobile Application on Professional Technical Terms for University Students of Faculty of Business Administration Rajamangala University of Technology Phra Nakorn were as follows: 1) to design prototype of of Mobile Application on Professional Technical Terms for University Students of Faculty of Business Administration Rajamangala University of Technology Phra Nakorn and 2) to assess teachers and students’ expectations and satisfaction towards the Prototype of Mobile Application on Professional Technical Terms for University Students of Faculty of Business Administration Rajamangala University of Technology Phra Nakorn The random sample consisted of 50 teachers and students. The tool used in this research was a questionnaire. The data were analyzed by a percentage means and standard deviation. . The research details were as follows: General data – there were 50 total respondents (100%). The majority were female (54%) and 60% of respondents were in the 20-24 year-old range 40% education level from a Bachelor of Business Administration and 30% of Accounting Major Samples expectations and satisfaction– the level of expectations was high at X = 4.71 S.D.= 0.42 and the level of satisfaction was similar at X =4.67 S.D.= 0.47 From expectation and satisfaction it was found that there was the highest level of expectation and satisfaction. It can therefore be concluded that this research has achieved the objectives.

The research projects of Development of Thai Silk Scrap of “Panpum” by Thai Painting Technique. The purpose is as follow. 1) To study the product development process Thai Silk Scrap of “Panpum” . 2) To study the satisfaction of the target group on the product Thai Silk Scrap of “Panpum” . The results revealed that 1) The experts from 5 person commented that Development of Thai Silk Scrap of “panpum” by Thai Painting Technic from the sewing. It can be used in the field home economics for 3 persons but it can’t be used for 2 persons because the silk scrap was quite high Prices and also famous. Later Experts 4 persons give opinion that can development but 1 person give opinion that can not development because writing may not be clear. In writing Thai motifs on a piece of silk to be a variety of petals. 5 experts give opinion that was a conservation invention. Finally 5 experts give opinion that patterns were appropriation to make development. They don’t need more patterns. 2. Satisfaction of target group Thai Traditional of “Panpum” When considering each found as following. Creative was high satisfaction with average 4.23 . Appropriate was high satisfaction with average 4.13 Beauty was high satisfaction with average 4.11 color tone was high satisfaction with average 4.05 General shape of the Thai traditional “panpum” was high satisfaction with average 4.02 . And design was high satisfaction with average 3.66. Overall consideration was highest with average 4.84 “Thong noy” Tray with pedestal. When consideration each topic found as following.
