Nowadays Eye tracking technology is the next challenges of human computer interaction (HCI). This technology can help people all over the worldaccess computers through systems that use gaze control and especially important for people with physical disability. This research presents a system of assistive technology base on an eye-tracking interface while supported the communication system for independent living of persons with disabilities usability. The primary method of this system consists of a selection of pictogram buttons on three websites which used a low-cost eye-tracking device. The evaluation used the throughput of standards for computer pointing devices as a measurement of user performance to look at an on-screen target and dwell on it for 500ms for selection. The results showed that ten participants with a disability can be pointing and selection their overall mean throughput was 1.08 bits/s. Moreover the overall users of respondents were rather satisfied with the system. Consequently eye tracking technology is a great tool for interaction in the web application for a user with a disability.

With the objective 1) to develop communication system operating simulation program using GUI MATLAB 2) To find the efficiency of communication system simulation program using GUI MATLAB and 3) To compare the calculation results from the developed program with the calculation results The parameters of the high frequency transmission line which were developed to be programmed Classified by type of transmission lines in the air depending on the frequency and use including two-wire transmission cables. Twin-plane transmission cables And coax signal transmission lines The program components are divided into 3 screens namely the main screen the main program screen And parameter calculation screen Systematic quality and efficiency checks by 5 experts That has specialized expertise The tools used in the research were the quality inspection evaluation form which is divided into 2 parts which are part 1 program testing and part 2 testing the statistical system used for data analysis including mean percentage and standard deviation. The research found that 1. The result of the development of communication system simulation program using GUI MATLAB with the structure of the program design Dividing operations into 3 main parts Namely the calculation of two signal transmission lines. The calculation of the twin plane transmission line program And the calculation of the coax transmission line program n each part of the program calculation there is a working principle of the program. Each part of the calculation of the program has a working principle of the program. Divided into the terms of the scope of the transmission line Calculate capacity Calculate the conductivity Calculate inductance Calculate resistance And calculate the impedance value In which all calculations can show calculation results Select the calculation of various transmission lines. The program that the research team developed The signal transmission line is divided according to the type of usage and frequency. There are 3 signal transmission lines which are two-wire transmission lines. Twin-plane transmission cables And coax signal transmission lines 2. The result of finding the efficiency of the communication system simulation program using GUI MATLAB is divided into 2 parts. Part 1 Result of the language order and ability test for all 5 sub-processes Is correct No errors in the process In which each working process is linked as designed Overall the system development can work without errors. And when evaluating system acceptance It was found that the developed program could be used as a research tool. When considering each aspect found that Design. Design standards Design quality And the structure that is not complicated design is accepted by experts As a percentage between 82% - 85% Working process sorting work process Understanding of working language is accepted by experts. As a percentage between 82% - 87% And in front of work how to work in each work Compliance with user needs is accepted by experts. As a percentage between 80% - 95% And part 2 finding the performance of the communication system simulation program using GUI MATLAB developed found that the developed program has a high level of performance (x ̅ = 4.16 S.D. = 0.35) 3. Comparison between the calculated results from the developed program and the calculated results With matching calculation results Therefore shows that The developed program can be used in place of efficient calculation by hand.

The objectives of this research is to study (1) The demographic of mobile users effected to mobile network’s decision making (2) The creating shared value of mobile network effected to mobile network users’ decision making. The sample population consisted of one thousand two hundred mobile network users. The instrument of research was a questionnaire. The Statistical Package for the Social Sciences (SPSS) for Windows computer program was applied for analyzing formulating and tabulating the data collected. The techniques of descriptive statistics used were percentage mean and standard deviation. Techniques of inferential statistics utilized were t-test one-way analysis of variance (ANOVA) in order to analyze differences between variables taken as a group. If there is a statistically significant differences found between pairs in a group Scheffé’s pair testing were deployed. Multiple Regression Analysis were applied in order to analyze the demographic of mobile users and creating shared value of mobile network effected to mobile network users’ decision making. The results were as following: 1. The all factor demographic of mobile users effected to mobile network’s decision making effected to mobile network’s decision making. 2. The creating shared value of 3 brands effected to mobile network’s decision making effected to mobile network’s decision making.

This is to study the audience demographic have a relationship with audience behavior in watching of Insight the Parliament of people in Bangkok Compare the audience behavior have an effect and satisfaction and uses and gratification on insight of parliament and to study the audience’s opinion and satisfaction has a relationship with audience’s understanding and benefits on Insight the Parliament by using survey research. The sample was 20 years old and over from targeted 400 people who are in Bangkok and ever watched this TV program. The research instruments were questionnaires and collected data was analyzed by SPSS. The statistics used for data analysiswere frequency percentage average and standard deviation. The statistics used to test the hypothesis was t - test. And statistical analysis of the difference between averages was One - way ANOVA.
