This research aims to for the development of an automated message response system using the LINE bot program for supporting information technology work. For supporting the reporting of computer problems the Internet the use of audiovisual equipment within the Faculty of Business Administration. Including basic troubleshooting for users. The results showed that developing an automated message response system using the LINE bot program. For IT support the use of Line Bot by using Line to report problems enables better interaction between users and device administrators. Allows users to be aware of basic solutions. Which is also a convenient and quick way to report problems save cost because within the area of the Faculty of Business Administration Rajamangala University of Technology Phra Nakhon has full internet service that the lecturer and staff can connect internet at all times.

This project was made in topic “The Development of Internet Management System in The Form of Programming Via API Internet : A Case Study of BanTiLiaPa Border Patrol Police School” aims to develop the internet system management to be efficient and facilitate the internet system management easier. This system is working through Mikrotik internet network that developed by using PHP to design website to improve the users. For using Bootrap for to design website as well as design the system by using Atom program to edit coding in the internet system management website page. The study found that This system can work to cover the educational objectives that have been laid. Can be used to develop the internet management system very well And also helps to facilitate the management of the internet system

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 study of the efficiency of fuel consumption by adjusting the fuel injection pressure is basically one optimization method to maximize the engine combustion. In this current study the Honda wave 110 cc. engine has been used to test in particular the fuel injection by adjusting the pressure of injector. To control the pressure of injection was made by automatic valve injectors with three different pneumatic pressure which were 2 2.5 and 3 bars respectively and the similar running distance of 5km. The results showed that at 2 bars the obtained fuel saving was 1020.68 km/L and the speed at 25.23 km/h which corresponded to the highest CO2 emissions during the engine combustion.

The objectives of this research were to develop of transmission line calculation program based on usage and frequency consisting of the two-wire transmission line twisted pair transmission line and coaxial transmission line. The program was developed in the form of graphical user interface in Malta. The developing and testing results found that the program was correctly capable to calculate capacity conductance inductance resistance and impedance for each transmission line usage and frequency. The results from the program with black box testing by five experts and twenty system users found the average and the standard deviation of results form computer experts were 4.04 and 0.36 respectively while those of results form the system users were 3.88 and 0.48 respectively. Conclusion it showed that the efficiency of the calculation program was a high level and can be used as a teaching and learning as well.
