The purposes of this study were t~ investigate the influence of color psychology on low vision people affecting product design and to conclude color psychology applied for low vision people. The study comprised five points. First point was to study what colors that people with low vision could see clearest by ranking. Second point was to study what they liked the most colors. Third point was to study what complementary colors that they could see the clearest color by ranking. Fourth point was to study how the sample groups felt about colors. And fifth point was to study that they could distinguish strength or weakness in a color (intensity). The instruments used in data collection were the questionnaires and set of stimulated color charts which utilized as stimuli to induce answers from respondents in the surveying process.

The purposes of this study were to investigate the development of Skill Learning Kit: Thai Braille Alphabets and to facilitate the children with visual impairments for Thai Braille alphabets practice to increase their capabilities of Thai Braille Alphabets skill. The study comprised three points. First point was to test about the Thai Braille alphabets learning of sample group. Second point was to study the appropriate scales of the usage of Skill -Learning Kit: Thai Braille Alphabets. And third point was to examine the suitable function of the Skill -Learning Kit : Thai Braille Alphabets. The instruments used in data collection were the questionnaires from respondents in the surveying process.

This research is an exploring research to be connected with the main purpose of learning about the satisfactions in working as other sides for supporting personal consists of supporting for government officers supporting for government staffs university staffs permanent employees and temporary employees in total 635 people. There are only 360 people of samples from the total as mentioned to be analyzed the factors and other satisfactions the result of this research is the level of surrounding factors in working as showing the average rate for all over as the normal level. In comparing with the personal factor and satisfaction were found that Male are much more than Female about satisfaction in all factors mentioned. And also single government staff there is most of satisfying than married and divorced status. Additionally the level of satisfaction will be reduced respectively as referring with ages type of working opportunity colleague and facilities but the satisfaction of reward will be much more which is depended on ages. Moreover the experienced staff will be much satisfied as follows: Type of working Reward Opportunity and Facilities but another side to be less satisfied are Colleague. However the responsibility of members in their family will be less satisfied almost all sides. Another thing the position is the most of satisfying colleague & facilities are next and reward & opportunity to be promoted as the last one. Moreover chief executive position satisfies more than head of department and operation respectively. Noise temperature dust smell air flow and colleague are the surrounding factors to be reflected with the satisfactions.

This paper proposes a design and implementation of transversal adaptive digital filter using LMS (Least Mean Squares) adaptive algorithm. The filter structure is based on Distributed Arithmetic (DA) which is able to calculate the inner product by shifting and accumulating of partial products and storing in look-up table also the desired adaptive digital filter will be multiplierless filter. In addition the hardware implementation uses VHDL (Very high-speed integrated circuit Hardware Description Language) and synthesis using FLEX10K Altera FPGA (Field Programmable Gate Array) as target technology and uses Leonardo Spectrum and MAX+plusII program for overall development. The results of this design are shown that the speed performance and used area of FPGA. The experimental results are presented to demonstrate the feasibility of the desired adaptive digital filter

The purposes of the research were to create computer assisted instruction for Mechanics of Materials Subject to find out the efficiency validation of computer assisted instruction based on the standard of 90/90 and to analyse the students learning achievement after using the computer assisted instruction. The subjects in the study were 17 second -year diploma engineering students enrolling at Rajamangala University of TechnologyPhra Nakhon. The researcher made the experiment by having the students pretest. Then they studied by using the computer assisted instruction focused on practicing basic turning. After the students had studied and had posttest. the efficiency of the computer assisted instruction was calculated as well as the learning achievement was analysed. The research result revealed that the efficiency of the computer assisted instruction was at the standard of 90 / 90. Moreover the learning achievement after using the computer assisted instruction was different at the significant level of 0.05.
