This research aims to study the relationship between profitability including gross margin operating margin net profit margin Return on Total Assets and Return on Equity and the SET index and dividends. The information is collected from the listed companies on the Market for Alternative Investment (MAI). The data comes from the financial statements and the annual reports of 28 companies with profit with no consecutive loss for more than 3 years and a top-five maximum registered capital of each business category during 2013 – 2017 with the accounting circle starting from 1 January – 31 December of each year. The statistics used for data analysis are descriptive statistical analysis. The secondary data is analyzed in the form of arithmetic mean (Mean) Maximum Minimum and Standard Deviation to describe the characteristics of the Pearsons Correlation Coefficient Sample Analysis. The ratio that represents each group is then analyzed by Multiple Regression Analysis to find the relation with the stock price index and dividends. The results show that profitability including the profit margin Return on Total Assets and Return on Equity has the relationship with stock price index and dividend at 99% confidence level.

The aims of this research work were to enhance the impact resistance and processibilty of wheat gluten (WG) by the addition of epoxidized natural rubber (ENR) compared to glycerol. This work was divided into two parts: to study the optimum ENR content for improvement of WG and the effect of together functions between ENR and glycerol on the properties of WG. Tested specimens were mixed and prepared by internal mixer and compression molding machine respectively. ENR and glycerol were varied from 10 to 40 phr. The effects of modifier types and contents on WG were evaluated by tensile impact and water absorption testing and thermal analysis. Fracture behavior and rubber dispersion were investigate with scanning electron microscope (SEM). The result revealed that the increase of ENR or Glycerol contents led to the decreases in tensile modulus and strength except for modifier content of 10 phr whereas elongation at break and impact strength increased. Glass transition temperature (Tg) of modified WG tended to decreased with the increase of ENR or glycerol contents especially for glycerol. The presence of glycerol affected on the decomposition temperature (Td) values but those were unchanged for case of ENR. Water resistant of WG specimen was improved by the presence of ENR whereas the increase of glycerol led to weight loss at immersion time of 2880 min. For the effect of ENR : glycerol ratios it indicated that glycerol enhanced tensile resistances but suppressed impact and water resistances of modified WG by ENR. Sizes and dispersion of ENR particles were improved by the addition of glycerol. Tg and Td values of modified WG by ENR and glycerol increased when ENR fractions were increased.

The purposes of this study were to investigate the heat transfer and the vibration characteristics caused by front and back vented brake disc which had physically different shapes affecting braking distance. In accordance with the theory of heat transfer the heat transfer rates of two types of brake disc were different and played an important role in the deformation during usage. The single dynamometer was conducted to the experimental work as an engineering tool with boundary conditions according to JASO C406 standard. One degree of freedom (DOF) acceleration signals on the brake caliper were analyzed. The results obviously discovered that the back vented brake disc was able to reduce the vibration up to 43.5% comparing to the front vented brake disc in case of the braking temperature 200C initial breaking speed 50 km/h and the hydraulic pressure of 4 MPa. Besides the hydraulic pressure at 4 MPa generated the maximum vibration. Furthermore the initial braking speed and the braking temperature were also the important factors. Regarding braking distance results the results of the experimental work obviously discovered that the back vented brake disc created braking distance shorter than front vented brake disc. Besides there were important factors as braking temperature hydraulic pressure and initial speed of braking. Especially the high braking temperature caused an increase of deceleration and a decrease of braking distance. Moreover the high hydraulic pressure produced a deduction of braking distance and an increase of deceleration. Finally the initial speed of braking directly varied to the braking distance

The Research Shelf Life Extension of Kanom Jeen by Using Modified Atmosphere Packaging for Increasing the Competitiveness for Commercial: Case Study of Thap Luang Company. Study the use of modified conditions for extending the life of fermented rice noodle By using filling techniques under atmospheric conditions Divided into 7 levels which are normal conditions vacuum (vacuum) nitrogen gas (N2) 100 percent carbon dioxide (CO2) 100 percent nitrogen gas per carbon dioxide (N2: CO2) all 3 levels which are 60 percent. : 40 70:30 and 80:20 then to study the storage life of each condition from 0-15 and compare the physical properties Chemical and microorganisms such as pH value color measurement and total number of microorganisms found that Khanom Jeen noodles stored in modified atmosphere conditions have longer shelf life than those stored. At normal atmospheric conditions and vacuum conditions. Chemical analysis results show that ready-to-consume fermented rice noodle flour in all atmospheric modification conditions decreases pH over time. With values between 4.31 ± 0.00 to 2.99 ± 0.01 and fermented rice noodle flour stored at atmosphere modified with 100% carbon dioxide (CO2) gas packed in a sealed nylon / PET vacuum plastic bag. Store at room temperature. Can be stored for up to 12 days and found that the total number of microbes increased when the shelf life is longer but not exceeding the standard of community products (PhorChor. 500/2547 Knmhin) so the products are safe and not harmful to consumers. Consumer test results show that consumers like and are interested in buying Khanom Jeen products that use 100 percent carbon dioxide (CO2) at 75 percent.

This research aims to: (1) develop the training curriculum development for enhancing skills in general ability ( 2) evaluate the effectiveness index of the training curriculum development for enhancing skills in general ability and 3) study the samples’ levels of satisfaction. The samples in to study were 10 senior students in regular program. The research instruments included the training curriculum development for enhancing skills in general ability an evaluation of congruence a knowledge and skill test a questionnaire on training satisfaction. The statistics used were the effectiveness index percentages mean standard deviation and paired – sample T test. The results revealed that the training curriculum development for enhancing skills in general ability were highest level appropriation ( X = 4. 67) showing that it was possible for further use. From the pre and post tests on the knowledge and skill testing the trainees different score showed that there was improvement among the trainees at the significant level of . 05. The questionnaire result showed that the trainees were highest satisfied.
