The objectives of this research were to 1) develop the Multimedia Computer Assisted Instruction for Teaching Illuminant Engineering on Interior Lighting Design 2) compare learning achievement between before and after learning 3) evaluate students’ learning progress and 4) study students’ satisfaction on the Multimedia Computer Assisted Instruction. The sample studied were 28 third year students belonging to the field of electrical power engineering faculty of Industrial Education Rajamangala University of Technology Phra Nakon. The instruments of this research included 1) the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design 2) an quality evaluation questionnaire of the Multimedia Computer Assisted Instruction 3) pretest and posttest of learning achievement and 4) student satisfaction questionnaire on the Multimedia Computer Assisted Instruction. The results were as follow: 1. The efficiency of the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design was 81.45/85.71 which was higher than the criteria set of 80/80. 2. The mean score of posttest ( X = 12.68) was significantly higher than pretest ( X = 5.54) at .01 level. ง 3. The evaluation result of learning progress by the method of Average Normalized Gain was 0.77 which was in a high progress level. 4. Students’ satisfaction on the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design was at the level of the most satisfaction ( X = 4.80).

This survey research has a purpose to study the personality of students at the Mechanical Engineering Department Faculty of Industrial Education Rajamangkala University of Technology Phranakhon. The improvement of test questionnaire 16 PF (Sixteen Personality Test ) of Raymond B. Cat Resort from the total of 108 students who using a tiered Iandscape sampling (Stratified Random Sampling). Students from Mechanical Engineering. Tools used in evaluation of research data using a questionnaire and data analysis methods.Calculate overall percentage of arithmetic mean (arithmetic mean) on median comparisons t-test and F-test of students personality areas. Research results can be summarized as follows. 1. Personality with a teacher of mechanical cngineering students by age showed that all of the moderates.The average of the maximum a person is sincere and guileless disclosed. 2. Personality with a teacher of mechanical engineering students by age is found that the older students have different personality. And students over 27 years pf age are not timid than courageous. Students aged belwecn 23-27 years. 3 Personality on a teachers student in meehanical engineering disciplines. Ievels by an average score found that students with different rate lcvcls. It is a personality who loves to collect dissociation. Different found that students with grade lowcr than the2.00 level as people like humility.

This article presents the energy conservation of the wood furniture factory in Samutprakarn province by using engineering management technique. The electrical energy of 7408000 kWh per year or 25988055 Bath per year is mainly used in the processes including a heating energy system that is derived from wood scrap. After detailed audit it was found that 8 measures have a potential to improve energy efficiency. 7 measures for electrical energy can reduce the energy of 479837.60 kWh per year and the rest decreases heating energy of 120297.15 MJ/Year or saving the scrap of 9.4 tons per year. In order to assess economic possibility all measure also were considered. The result showed that it was worth to investment. In addition specific energy consumption (SEC) can be improved from 0.57 kWh/ft3 to 0.54 kWh/ft3 or diminishing of 5.26 %

The purposes of the research were to create and efficiency validation of computer Assisted for the courses of practiced to reading Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program Subject Engineering Materials Chapter 3-6 based standard and analyses the leaning achievement of the student after by using computer assisted instruction . The subjects in the study were 20. Diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning . After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction. And analyzed the learning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard Moreover after learning achievement at significant level of 0.05.
