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 research presents the development of a low rate and low power consumption low rate wireless network. Low rate wireless networks are cheap and comprised of a small fully autonomous processing communication and remote control devices. The purpose of this study is to develop the system for remote wireless lighting system. They will work with wireless network system (WNS). WNS has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each network node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The step of the experiment is creating main node and sub node in lighting area and transmission of control data between them with less electrical wiring. When wireless node not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode. We can reduce the use of electrical wiring; insulated insulation material or other that related to and include energy too.

This research aims to study the application of kaolin with coconut meal plywood from corncobs and durian peel in concrete masonry unit wall for increasing effective heat protection and lightweight. The ratio of cement type 1: kaolin is equal to 1: 60 by weight. The kaolin is replaced by fiber include coconut meal fiber corn cob fiber durian peel fiber with 1.67% 3.33% and 5% by weight of kaolin. The kaolin concrete block mixed with fiber sample size is formed to 6.9 x 39 x 19 centimeter with the hydraulic compactor. The samples tested in physical and mechanical properties follow the TIS 58-2533 standard. Resulting their fibers can reduce the density thermal conductivity and compressive strength and increase the changing length and water absorption of kaolin concrete blocks. The kaolin concrete block without fiber has highest compressive strength followed by the kaolin concrete block mixed with corn cob fiber the kaolin concrete block mixed with coconut meal fiber and the kaolin concrete block mixed with durian peel fiber has lowest compressive strength respectively. However their fibers have possibility to be composite materials to reduce weight of kaolin concrete blocks.

The Development of Computer Multimedia through the Internet Teaching tool for Lighting for Broadcasting Course (Undergraduate Level) Rajamangala University of Technology Phra Nakhon

The purposes of this research are 1) to create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) 2) to develop and to find out quality the create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) and to achieve efficiency according to a set of 90/90 criterion. The samples for this study were 48 second year students of Bachelor of Technology Program in Radio and Television Broadcasting Technology studying this course in the first semester of 2011 academic year at Rajamangala University of Technology Phra Nakhon. The samples were selected by simple random sampling. The research tools used are the computer multimedia through the Internet an achievement test evaluation forms for quality assessment. Statistics used for analyzing the data were percentage and mean. The results of the study revealed that the computer multimedia instruction through the Internet was ranked as a very good level by content experts and as a very good level by educational technology experts and had its efficiency of 94.80/96.60 it was higher than criteria set 90/90
