This special project is 1) to develop World Phenomena Game for Grade 3 students 2) to measure knowledge after using World Phenomena Game and 3 ) to study user satisfaction after playing World Phenomena Game. In this study an offline ADVENTURE RPG personal computer game was created and validated by 3 professionals with medium level. Then the game was put to test with a sample group of 10 Satrivoranart Bangkhen School’s Grade 3 students. Quiz and questionnaires were distributed to collect student’s knowledge and satisfaction. During data analysis a attest was performed with t-Test = 1.83 p=0.05. indicated that student knowledge after playing game was statistical higher than their knowledge before playing game Furthermore overall user satisfaction was at high level (𝒙̅=4.30 : SD=0.90).

The research aimed to study parameters affecting the stress intensity and stress distribution as well as the deformation of run-flat tires for passenger cars using the Finite element method. Both experimental methods and finite element methodologies were employed in the research process. The results were obtained by comparing the strain values from the two methods to demonstrate the consistency of both methods. The differences in their strain values were shown in the range of 10-16% confirming the analyzing capability in this problem through the Finite element method. At the pre-processing step both procedures and methods were proven with SolidWorks simulation program together with experimentation. These consequences were incorporated to assist the design of run-flat tires. Parameters affecting the stress intensity and stress distribution were evaluated to understand the effects on deformation of the new designed run-flat tires. The reverse engineering process was thus applied in the research process by scanning with FARO P06-05 and creating solid modeling 3D models with Geomagic program for SolidWorks. These could assist in designing the reverse- engineered tire pan. Three components were additionally designed to support the ease in assembling or removing run flat tires from the pan. Run flat tires were finally designed for passenger cars typically the most common small cars. The weight of this car was limited at not more than 1800 kg and the thickness of the wheel pan was 17 inches. The analysis information assumed that the vehicles weight was distributed equally throughout all 4 wheels. The material used to make the run flat tires was a composite tire type that could withstand the pressure occurring from the weight of a passenger car. The results of the analysis demonstrated that the maximum stress on the run flat especially at the position where the run flat surface was in contact with the road was 30-45 MPa which depends on the location of contact with the road. Thus it affected the stress distribution on the wheel pan. The parameters obtained from the study affecting the stress distribution and deformation were accounted to be such types of materials made for run flat tires cross-sectional area and width of run flat tires.

The objectives of this research were to study the stress intensity in run-flat metal wheels and to design a new type of run-flat wheels that can be used in a small armored regular truck. Experimental methods and finite element methodologies were applied in the research process. The results obtained by comparing the strain values from the two methods demonstrated the consistency of both methods. The differences in stress values were in 10 -16 percentages which could confirm the capability to analyze the stress distribution and deformation of run-flat by a finite element method. Proven processes and procedures in Pre-processing with SolidWorks Simulation were utilized to design run-flat wheels and a reverse engineering process was next used to create wheel rims and design the cross-sectional shape of new run-flat wheels made of composite materials which have an important reactant; a polymer group and aluminum oxide powder added to enhance the strength. The designed parameters consisted of 1) the width of the run-flat wheels 2) the internal and external radius in which the internal radius depending on the size of the wheel rim and the outer radius which is a variable that determines the height of the run-flat wheels 3) the design of a lockset for tightening the run flat wheels to the wheel rims 4) materials used in the structure of the run-flat wheels and 5) tire pressure. The run-flat wheels designed and built into three-piece parts were designed for ease of wheel assembly or disassembly out of the wheel rims. By analyzing the intensity of stress accumulated in a conventional run-flat wheel (run-flat metal wheel) the stress generated in a run-flat wheel did not exceed the limit of the Yield stress and had a safety value between 3-5 times for new run flat wheels with a maximum stress of 26 MPa. Sizing and cross-sectional dimensions of run flat wheels thus resulted in stress which was in the range that could be withstood and acceptably employed. It was also possible to reduce the height of the flat wheels to make the rear flats lower and increase the width of the run flat wheels which would help distribute more weight to the wheel rims.

The purposes of this study were 1) to study the basic recipe of Khanom Gleeb- Lamduan. 2) To study the types of Job’s Tears flour used as a substitute for wheat flour in the recipe of Khanom Gleeb-Lamduan. 3) To study the quantity of supplemented xanthan gum was studied in the recipe of Khanom Gleeb-Lamduan from Job’s Tears flour to improve texture. 4) To study the chemical composition of Khanom Gleeb-Lamduan from Job’s Tears flour. The results of the sensory quality evaluation with a 9-point Hedonic scale favorability score by 30 taste panelists found that the basic formula of Khanom Gleeb-Lamduan that was selected contained 55% of the ingredients including wheat flour soybean oil and icing sugar 27.50% and 17.50% respectively. The results of a study on the type of Job’s Tears flour suitable for substitute for wheat flour for the development of gluten-free Khanom Gleeb- Lamduan recipe. It was found that Khanom Gleeb-Lamduan made from dried milled job’s Tears flour had a higher score on the tasters favor than that made from commercial milled Job’s Tears flour and boiled Job’s Tears flour (p≤0.05). Tasters rated their preference for Khanom Gleeb-Lamduan from Jobs Tears flour with added xanthan gum to improve texture characteristics in the amount of 1% of millet flour preferring it over Khanom Gleeb-Lamduan with Jobs Tears flour added at the rate. 0.5% and at a rate of 2%. Khanom Gleeb-Lamduan had average liking scores in terms of appearance color smell taste texture (crusty) and overall liking was 7.33 7.40 7.86 7.53 7.76 and 8.10 respectively which were in moderate to high liking level. The approximate chemical composition of 100 g of Khanom Gleeb-Lamduan from JobsbTears flour contains 6.75 g of protein 27.46 g of fat 2.64 g of moisture 62.21 g of carbohydrates 0.94 g of ash and 522.98 kcal of energy which is similar to that of the basic recipe of Khanom Gleeb-Lamduan using wheat flour but it has a higher ash content than the basic formula. This is because Jobs Tears contains high amounts of many minerals. Khanom Gleeb-Lamduan from Jobs Tears flour is therefore a healthy snack for general consumers. In particular consumers with gluten intolerance can also eat it.
