The purpose of this research is to study the factors affecting the students๛ achievement and to create the model of the achievement predictive equation on Research Methodology subject Rajamangala University of Technology Phra Nakhon Chotiwet Campus. This research is a correlation research. The population are the third year (4-year-Programme) students of Chotiwet Campus majoring in Food and Nutrition totaling 133. The results of the study revealed that there were two factors affecting the students๛ achievement on Research Methodology as follows : (1) cummulative grade point average and (2) students๛ problem of how to adjust to the study environment. The above-mentioned factors can be formed as model of the Research Methodology achievement predictive equation as follow yˆ = 11.079+3.349 x1 - 1.081 x7

The research was to study and compare learning styles of students of the faculty of Home Economics RIT Chotiwet Campus deviding into sex department and level of education. The sample consisted of 249 students in the second semester of academic year 2003. The 5 rating scale questionnaire consisted of 6 learning styles classified by Reichman and Grasha : Independent Dependent Avoidance Collaborative Participant and Competitive consisting of 60 items. The reliability was 0.71. The data were analyzed by using SPSS for window. The statistics used were percentage mean standard deviation t-Test One -Way ANOVA and Tukey HSD. The results were as follows: 1. Most students occupied collaborative and participant learning styles then dependent independent competitive and avoidance respectively. 2. There was only one difference between male and female students learning styles that was avoidance. 3. Students from different majors had 3 different learning styles which were dependent collaborative and competitive. 4. Students who were in different levels of study had 1 different learning style which was collaborative.

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 objective of this research was to design run flat wheels made of aluminum for passenger cars and investigate the stress strain and deformation of run flat wheels and their components. The original 17 inch run flat wheels were made of AISI 1020 steel with a weight of 11.3 kg per wheel. The main problems were from the high-level weight as well as the untighten connection together with noticed gaps taking place between the run flat wheel and the wheel. Therefore in this study the AISI 1020 material was changed to the Aluminum 6063 T6 material. The Numerical methodology using the finite element program was also chosen to indicate the comparative differences in the strain values engaged at various locations of both run flat wheels and pan wheels. The results obtained from both approaches using SolidWorks Simulation Program uncovered the consistent results of the experiments with a 10-16% difference in strain values. The complicated 17 inch wheel pan model was next built using reverse engineering and employed as a key reference to design the cross-sectional area of the new run flat wheels made of Aluminum 6063 T6. All these two parts could be connected tightly. The SolidWorks Simulation program was employed to design and examine the strength of both designed aluminum run flat wheels made of aluminum and the wheel pan made of 17 inch aluminum alloy to build passenger cars. The finite element model was furthermore applied for the run flat wheels made of aluminum 6063 T6 and it provided run flat wheels composed of 2 light weighted pieces. The stress strain and deformation measured were proven and suggested in the test. The output Von Mises stress did not exceed the Yield stress within the linear elastic limit and 3 times safety integrity value. The results from the study were that the obtained run flat wheels allowed the driver to continuously drive for a further 50 kilometers at a speed of 50 kilometers per hour without losing control. They allowed possible tire repairing or replacing when situated in a safe and convenient location.

The objective of this study is to improve the efficiency in manufacturing process of Arabian-style ventilation bricks with a new production method that uses a machine. The study focuses on all steps of productions in order to increase productivity. After the experiment the study shows that the improvement of ventilation brick manufacturing includes the increase in production volume from 20 pieces per day to 50 pieces per day representing an increase of 76.19 percent; and the decrease in production cycle time originally from 1401 minutes per piece to 97 minutes per piece representing a decrease of 93.07 percent respectively.
