This research aims to study the usage pumice rock fragments to develop paving block product for community. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 6 ratios. The paving block samples are casted in 30 x 30 x 5 centimeter in dimension. The paving block sample testing follows the TIS 378-2531 on concrete flooring tiles. From the experiment bending strength and thermal conductivity of paving blocks with high quantity of pumice rock fragments are lower than paving blocks with low quantity of pumice rock fragments but the water absorption of paving blocks with high quantity of pumice rock fragments are higher. However all of pumice rock fragments paving block samples with lower than 1: 2: 2.4: 0.6: 0.6 of ratio can pass the standard and the surface temperature is lower than other covering materials about 2 degree Celsius.

This research aims to study how to use stones Pumice Products is interlocking block for community development. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 5 ratios. The products were tested by the community TCPS 602-2547 (2004) (Thai): interlocking block. The results showed that interlocking block of stone pumice much a compressive strength and thermal conductivity under a block of stone pumice less. The water absorption is increased When a block of stone pumice much. The optimum ratio and the use of waste rock Pumice highest ratio of cement to stone dust on the stone Pumice water in a 10: 6.4: 0.6: 0.45 to 10: 6.1: 0.9. 0.45 by weight.

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 objectives of this study were 1) to analyze the capability contributing to the competitive advantage 2) to synthesize the key performance indicator from the internal factors 3) to examine the level of competitive capability and 4) to develop the strategy to enhance the capability of competitive advantage in the faculty of Mass Communication Technology Rajamangala University of Technology Phra Nakhon. The samples used in the study included 71 interviewed stakeholders in the university and 400 survey participants. The findings pointed out as follows: (1) the strategy t enhance the competitive advantage were defined in five aspects: curriculum educational management personnel learning environment and image and alumni association (2) the level of competitive advantage was rated high in the following order: personnel educational management curriculum and image and alumni association. The learning environment was also in high level.

This research Reducing Attrition Rate of RMUTP First-year Undergraduate Students Using the Pre-university Program was done to find out the relationship between the pre-university program and RMUTP attrition rate. In addition to the first objective this study aims to find the satisfaction of students toward the learning program. Using a mixed methodology qualitative and quantitative data were collected from students and subjects related to RMUTP pre-university program. In order to describe the research question those data were analyzed together. The results were as follows: 1. Rajamangala University of Technology Phra Nakhon has offered pre-university program for 3 years. This year there are 13 departments within 5 faculty offered the program. 2. A statistical analysis showed that 71.24 percent of the sample group was highly satisfied with the pre-university program. Twenty-seven percent was moderately satisfied with the pre-university program. Only 1.29 percent was less satisfied with the pre-university program. 3. The pre-university program is necessary and can influence students’ grade points. The sample group also suggested teaching subjects to be matched with the subject study in Semester 1. 4. During the past 4 year drop-out is still at the same number to all faculties regardless of the pre-university program. Therefore the cause of high drop-out number might come from other factors that cannot be cured by the pre-university program.
