The design of plastic injection mold requires precision and efficiency of the injection. Therefore mold design engineers need to determine the size location and number of the gates to fit the length of the plastic flow in the work piece so that when the injection mold is built they’ll get the complete and specified specimen. This research was conducted to study the influence of injection flow channel thickness affects the flow index. Poly ethylene high density High density polyethylene HDPE was used in the experiments. The flow of plastic was Spiral Test according to ASTM: D 3123-94 with rectangular cross-sectional area of 6 mm. wide 6 mm. pitch. It was found that the thickness of the flow channel at 0.51.01.5 and 2.0 mm. which has the best flow rates at the best injection speed at 25% the injection pressure at 30% and the flow distance of 52 116 238 and 299 mm respectively with the plastic melting temperature between 190 C and 220 C.

The research studied results of integrated learning management in flower arrangement techniques subject of students from the bachelor’s degree in Home Economics Business Administration program Rajamangala University of Technology Phra Nakhon. The researchers provided the cooperative learning and selected three units of flower arrangement techniques subject consisting of materials and tools for arranging flowers creative flower arrangement and international flower arrangement. The research samples were the second year students of Home Economics Business Administration program. The research methods used in this study were a learning achievement form a satisfaction form and a participant observation form. Results of the study found were: 1. The effects of cooperative learning on students flower arrangement techniques subject achievement was found that there was a statistically significant difference between students pretest and post-test scores at the level .05. 2. The satisfaction of students toward flower arrangement techniques subject was at the highest level ( x = 4.00). It showed that students’ attitudes toward cooperative learning were at good level.

The purpose of this research was to assess the knowledge and understanding utilization and satisfaction of students toward learning activities in flower arrangement subject. The research sample was 93 of the first year students majoring in Home Economics Business Administration and studying the flower arrangement subject in the second semester of the academic year 2013. The research methodology was the rating scale questionnaire. Data were processed and analyzed by frequency percentage and mean. For the assessment of the students’ knowledge and understanding toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.90. For the knowledge it was at the high level with the mean of 3.82. For the ethics and moral it was at the high level with the mean of 3.79. For the cognitive skill it was at the high level with the mean of 3.78. For the interpersonal skill and responsibility it was at the high level with the mean of 3.70. For the psychomotor skill it was at the medium level with the mean of 3.42. For the assessment of the students’ utilization toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the interpersonal skill and responsibility it was at the high level with the mean of 4.20. For the knowledge it was at the high level with the mean of 3.92. For the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.84. For the ethics moral and it was at the high level with the mean of 3.77. For the psychomotor skill it was at the high level with the mean of 3.66. For the cognitive skill it was at the medium level with the mean of 3.44. For the assessment of the students’ satisfaction toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the interpersonal skill and responsibility and the ethics and moral it was at the high level with the mean of 3.98. For the knowledge it was at the high level with the mean of 3.81. For the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.72. For the cognitive skill it was at the high level with the mean of 3.56. For the psychomotor skill it was at the medium level with the mean of 3.52.

This research aims to Test Melt Flow Index Spiral Test according to Standard ASTM : D 3123-94. To compare with this Standard the Melt Flow Index Spiral Test of HDPE PP and ABS which determined by the manufacturer was tested in various sizes. The test and the results were as follow:

This research studied the flow of fluid through a rectangular barrier with the Lattice Boltzmann Method. The concept of this method relies on the streaming and collision of particles with respect to the conservation laws of mass and momentum. The objective of this research was studied patterns of fluid flow through the obstruction and Reynolds number to affect the flow pattern. The simulation showed that the flow pattern changes from laminar flow to turbulent flow when Reynolds numbers increased. In accordance with the theory.
