This research aimed to investigate perception attitude and behavior ofRajamangala University of Technology Phra Nakhon undergraduate students on 3Dpolicy - based activity Participation and the relations among perception attitude and behavior. 3D aspects include Decency Democracy and Drug-free. The data werecollected through 400 RMUTP undergraduate students from nine faculties in 2010.Data analysis employed frequency percentage mean ( ) standard deviation (s.d.).Statistics used for hypothesis testing included t-Test; to compare between two variables F-Test and One-way ANOVA; to compare more than two variables and Pearson Product Moment Correlation Coefficient. The results of study found that RMUTP students perceived news releases on 3 D policy of the university at the average level. In the meantime their overall attitude towards 3D policy campaign was rated in average level. The attitude towards Decency was at high level and Democracy and Drug-free were considered average. The student participation in 3D –based activities was rated at high level when considered by individual and overall aspect. Hypothesis testing resulted as follows: 1. Students with different gender had different perception of 3D policy with a statistical significance at .05. However there were no significant differences at .05 among students from different faculty. 2. Students with different gender and faculty had different attitude towards 3D policy with a statistical significance at .05 3. The participation behavior on 3D-based activities of students with different gender and faculty was different. 4. The perception of 3D policy new releases had a positive correlation with 3D- based activities participation behavior. 5. Attitude towards 3D policy of the university had a positive correlation with 3D- based activities participation behavior.

During the rice processing the possible situations of rice kernel cracking and breakage are commonly occurred and these consequences cause a low marketing price. According to this issue the real-time observation and together with the knowledge base of mechanical properties should be essentially helpful in detection of these defect observations. The objective of this work was established to study the mechanical stress-strain properties of rice kernels via our in-house pneumatic system design. We found that stress-strain of RD6 RD15 Phitsanulok 2 and Khao Dawk Mali 105 were greater than KhaoYipun DOAI with moisture content of 20% w.b. These results tentatively indicated the mechanical stress-strains occurred were from the difference of rice shapes. Moreover we could recognize that the characteristics of these various shapes significantly followed the scaling law of the relation between strain and time. We also found that the breaking force was different value for rice varieties. This parameter obtained can be such a high potential approach that can be used for further developing in the quantitative classification of rice varieties.

The aim of this is to study the relationship among the parameters such as demographic characteristic and the utilities and media explosures of the student of RMUTP THEWES CAMPUS by using surveying research for 303 sampleis.

This research aimed to examine knowledgeexposureusage and gratification towards alternative energy information of inhabitants in Bangkok. The data from the samples were collected by questionnaires. The findings were as follows; 1. The alternative energy internet information exposure differs significantly among the sample groups of different sex. 2.The media expusure through televisionsraduisnewspapermagazine and internet differs significantly among the sample groups of different age. 3.The media exposure through radios and newspapers differs significantly among the sample groups of different income. 4.The media exposure through televisions and interne differs significantly among the sample groups of different educational background. 5.The media exposure through televisionsradios newspapermagazine and internet differs significantly among the sample groups of different career. 6. The knowledge on GasoholNGV and Biodiesel differs significantly among the sample groups of different age. 7.The knowledge on Gasohol and Biodiesel differs significantly among the sample groups of different income. 8.The knowledge on Biodiesel differs significantly among the sample groups of different educational background. 9.The knowledge on Biodiesel differs significantly among the sample groups of different career. 10. The internet usage and gratification differs significantly among the sample groups of different internet exposure.
