The survey research aimed to: 1) study the behaviors of self-directed learning; 2) compare levels of self-directed learning behaviors which is classified by personal status; and 3) study guidelines for self-directed learning. The subject obtained through stratified random sampling consisted of 319 first-fourth year undergraduates of the Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The research tool was a questionnaire. The frequency percentage mean standard deviation t-test and ANOVA were used for data analysis and hypothesis testing. The results were as follows: 1. The overall level of students’ behaviors for self-directed learning was high (X = 3.74; S.D.= 0.74) that were self-evaluation competency (X = 3.89; S.D.= 0.74) self-management competency (X = 3.75; S.D.=0.76) self-learning competency (X = 3.74; S.D.=0.70) self-searching competency (X = 3.72; S.D.=0.72) and characteristics of self-directed learners (X = 3.59; S.D.=0.77) respectively. 2. There was no difference of self-directed learning behaviors when genders and educational levels were considered. In contrast there were statistically significant difference at 0.05 when academic performance was considered. 3. The overall level of students’ opinions on guidelines for self-directed learning was high (X = 3.51;S.D.= 0.85) self-directed was academic matter (X = 3.74; S.D.=0.76) physical matter (X = 3.41 ; S.D.=0.93) management (X = 3.40; S.D.=0.87) respectively.

The survey research aimed to: 1) study the levels of self-development needs in preparation to enter AEC; 2) make a comparison of the students’ needs levels in aspects of personal data; and 3) propose appropriate forms of activities to be used in the development. The subject obtained through stratified random sampling consisted of 321 first-fourth year undergraduates of the Faculty of the Home Economic Technology Rajamangala University of Technology Phra Nakhon. The tool was a questionnaire. To analyse data the frequency percentage mean standard deviation t- test and ANOVA were used. The results were as follows: 1) The overall level of self-development needs was high ( X = 3.75). The needs for selfdevelopment in line with the Thai Qualifications Framework for Higher Education were high ( = 3.89). Moreover the level of needs conforming to Thai Graduate Preferable Qualifications for the ASEAN Community was moderate ( X = 3.46). 2) There was no statistically significant difference ( p<0.05) of the self-development needs level when genders educational levels or academic performances were considered 3) As for the activities it was rated best to use training for the development of cognitive skills numerical analysis communication and information technology skills domain of psychomotor skills and knowledge on ASEAN Community rules and regulations; lecturing for knowledge on ASEAN Community rules and regulations; study touring for knowledge development; camping for ethics and moral interpersonal skills responsibility and language skills; and student inter institutional exchanging for neighbouring countries knowledge development.

The purposes of this research are to study: 1) understanding of water and electricity saving 2) water and electricity consumption behavior 3) to compare water and electricity consumption behavior classified by personal characteristics of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. This research was descriptive research. The sample group was specified to be 325 people by stratified sampling. The reliability of this questionnaire is 0.87. Statistics used was descriptive and inferential statistics. The research result revealed that: 1) The overall of understanding and knowledge regarding electricity saving of the students is in the moderate level. 2) The overall of water and electricity consumption behavior of the students is in the moderate level. 3) The comparison of behavior of water and electricity consumption specified according to personal characteristics could be summarized that the students in different genders classes and majors had identical water consumption behavior and the students in different genders and classes had identical electricity consumption behavior. On the other hand the students having different majors had statistically different electricity consumption behavior at 0.05.

The objectives of this research were to study the changes in the moisture of ground fish slices during drying with superheated steam combined with hot air and to compare the physical properties (in terms of color hardness toughness and shrinkage) as well as sensory evaluation of dried fish slices. Two drying methods were performed (i.e. superheated steam drying at 140 ?C combined with hot air drying at 110 ?C (SSD+HAD) and hot air drying at 110 ?C combined with superheated steam drying at 220 ?C and hot air drying at 110 ?C (HAD+SSD+HAD)). The ground fish samples were produced at sizes of 50?50?1.3 and50?50?2.2 mm (WDH). The samples with the initial moisture content of around 205-215% dry basis were dried until the final moisture content of about 20% dry basis. Results showed that the samples with 1.3 mm thickness had shorter drying times than those with 2.2 mm thickness. The samples dried by SSD+HAD and HAD+SSD+HAD were similar in the drying time. In term of qualities it was seen that the lightness of dried samples decreased but the hardness toughness and shrinkage percentage of dried samples increased when the samples thickness increased. Dried samples obtained from SSD+HAD had higher lightness hardness and toughness but had lower percentage of shrinkage than those obtained from HAD+SSD+HAD. Moreover it was found that dried samples obtained from HAD+SSD+HAD had the highest sensory scores.

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.
