Services marketing mix factors affecting students’ decision to pursue study at undergraduate level in faculty of science and technology of Rajamangala University of Technology Phra Nakhon
The purpose of this study was to study and compare services marketing mix factors affecting students’ decision to pursue study at undergraduate level in faculty of science and technology of Rajamangala University of Technology Phra Nakhon in 7 aspects: product price place promotion people process and physical evidence. The undergraduates were classified by gender major subjects educational background department of education achievement and domicile. The samples in this research were 93 undergraduates. The study participates selected by stratified random sampling and simple random sampling. The 84 item questionnaires of rating scales was used as the research instrument. Percentage mean standard deviation t - test for independent sample F – test and Scheffe’s test analysis were statistical method to analyze data. The results were as follows: 1. Services marketing mix factors affecting students’ decision to pursue study at undergraduate level in faculty of science and technology of Rajamangala University of Technology Phra Nakhon all aspects were in moderate levels that price was the highest while process and promotion was in the lowest rank. 2. There was significant difference for services marketing mix factors affecting students’ decision to pursue study at undergraduate level in faculty of science and technology of Rajamangala University of Technology Phra Nakhon at the 0.05 level among undergraduates in different gender different academic years different educational background and different achievement. 3. There was non significant difference for services marketing mix factors affecting students’ decision to pursue study at undergraduate level in faculty of science and technology of Rajamangala University of Technology Phra Nakhon in different department of education and different domicile.
Potential of extracts of Ficus hispida linn for controlling germination and Growth of Weed in Rice Field for Increase the value of biodiversity and its sustainable use
The potential of extracts of the Ficus hispida Linn to inhibit germination and growth of barnyardgrass (Echinochloa crus-galli) a common weed in rice. The bark leaves and fruit of F. hispida isolated by the Maceration and extracted by the polarity of the solvent (Sequential Extraction) with organic solvents such as hexane ethyl acetate and methanol when each part of the crude extract was tested the type of phytochemical tested for germinate inhibition root length inhibition stem length inhibition and dry weight inhibition of barnyardgrass and selected extracts with highest inhibition to separation using column chromatography the fractions tested repeating. The results showed that 1. Crude methanolic extracts from the bark leaves and fruit of barnyardgrass at a concentration of 3000 ppm showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fractions methanolic extracts from the bark leaves and fruit of barnyardgrass on a separate with column chromatography found that fractions extracts F5 F8 and F2 showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition.
Taxonomy and distribution of the plant family Podostemaceae in Phitsanulok and Phetchabun provinces, Thailand
Recent explorations of Podostemaceae have discovered 2 new species to science (Dalzellia TWA-216 และ Hydrobryum TWA-198) from Phitsanulok Province and 3 more genera and six more species from previously known (2 genera and 4 species). Totally five genera and 10 species occur in Phitsanulok and Phetchabun provinces. Based on morphological and molecular evidence the taxa are classified into subfamily Tristichoideae including 2 genera and 3 species (Dalzellia 2 spp. and Terniopsis 1 sp.) and subfamily Podostemoideae consisting 3 genera and 7 species (Hanseniella 1 sp. Hydrobryum 5 spp. and Thawatchaia 1 sp.). The species found in both provinces are Hy. phetchabunense and Hy. tardhuangense while D. kailarsenii is found only in Phetchabun. The plants discovered only in Phitsanulok include Dalzellia TWA-216 Hydrobryum TWA-198 Han. heterophylla Hy. bifoliatum Hy. kaengsophense Th. trilobata and T. minor. Among the species found Hy. tardhuangense and Th. trilobata are also distributed to the Lao PDR and the rests are endemic to Thailand.
The evaluation of achievement of cooperative education program, faculty of science and technology, Rajamangala University of Technology Phra Nakhon
Objectives of this research were 1) to study the environment of coopertive education program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn and 2) to study the achievement of this cooperative education program towards the development of graduates competency in the first semester of academic year 2013. Three sampling groups were from educational institutes enterprises and students. The number was 240 in total. Tools used in the research was a questionnaire opened and closed form number 4 sets were 1) questionnaire for coordinator or cooperative education officer advisor and lecturers 2) questionnaire for the executives coordinators or heads of human resources 3) questionnaire for employees consultant 4) questionnaire for cooperative education students. Performance analysis of cooperative education in the part of educational standard and the operation of science and technology using the content analysis method to comparing their content to the standard of Thai Association for Cooperative Education. To study satisfaction by using application program for statistical analysis such as frequency percentage mean standard deviation of mean values and descriptive discussion. The overall findings form this study showed that every relevant had high satisfaction with the management of the Cooperative Education Program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn.
The relative rotation affecting to AC-Generator
The purposes of the research were; 1) to study the relative rotation of AC-generator 2) to study the angular velocities of magnetic coil and permanent magnetic influence generating voltage of AC-generator and 3) to construct predictive equations of generating voltage of AC-generator. By the 12-V 6-pole alternator of motorcycle Pearson’s correlation and regression analysis the findings revealed that: 1) At the lowest relative angular velocity of 376 rpm the generating voltage is 3.28 V. While the highest relative angular velocity of 2280 rpm the generating voltage is 22.98 V. 2) The angular velocity of permanent magnetic has great influences on generating voltage than the angular velocities of magnetic coil at the .01 level of significant and 3) function as below : Generating voltage = 0.806 (Velocity of permanent magnetic) + 0.634 (Velocity of magnetic coil)
