This research approach to study the development of interior wall for reduce energy consumption by air conditioning in the building. In order to be a prototype in the development of an industrial system for the export of green architecture in order to generate income for the community or entrepreneurs to bring money into the country to upgrade the industrial economy to be sustainable It is an architectural material that is compatible with the weather in Thailand. It can be used as a guideline for people interested in applying it to their own home building or disseminating through various media to reduce energy costs for a comfortable living. The objective is to study the factors that affect the development of wall paneling in order to reduce the energy burden of the air conditioner in the building in order to further the commercial production. The researcher collected data for the past 6 months not including other thermal energy. Used to calculate the energy consumption index for 2 building groups it was found that the electricity consumption of green buildings were 531100 kilowatt hours. And an average of 5.31 kilowatt hours per square meter While the non-green building has an average of 653360 kilowatt hours. And an average of 6.53 kilowatt hours per square meter As for the results of the data analysis the damage level is mostly at level 1 which is the wall surface and no obvious damage. Especially the 4th and 5th height is 1.55 meters and 1.85 meters from the floor level in the building. Damage level 3 is found at the height level 3 at a height of 1.00 meters from the floor level in the building. Assessment of damage caused to the interior wall of the building that occurred in 3 levels. The results of the data analysis showed that most damage levels were at level 1 namely the wall surface without obvious damage. Especially the 4th and 5th height is 1.55 meters and 1.85 meters from the floor level in the building. Damage level 3 is found at the height level 3 at a height of 1.00 meters and from the results of collecting moisture content in the exterior wall materials And analyzed to find the average for each of the 5 levels of height which are 0.55 meters 0.75 meters 0.95 meters 1.55 meters and 1.85 meters found that the buildings have different moisture content in each wall level (p <0.05). In conclusion this green building index equation can be applied to other buildings to reduce energy consumption and meet the standards of the green building. From the equation the electricity consumption can be predicted using the electricity usage index and systematically designed energy management in buildings. The area with the most damage will find the humidity in the range of 47% -98% the highest damage level 3 at an elevation of 0.80 meters from the floor level in the building

This research aims to study 1) to develop listening and speaking English students of Rajamangala University of Technology Phra Nakhon provide higher efficiency 2) to compare the achievement of listening. English speaking students of Rajamangala University of Technology Phra Nakhon before and after the experiment 3) to enhance the students self-learning of Rajamangala University of Technology Phra Nakhon using correct sentences to communicate in daily life 4) To produce teaching materials to be used by English language instructors or support staff within the Faculty of Liberal Arts. Rajamangala University of Technology Phra Nakhon in preparation for the ASEAN Community in 2015. Experimental study was conducted by using the selfaccess multimedia computer program to practice listening and speaking English skills. The researcher created 3 lessons to take the test in 8 weeks 3 lessons for 1st year Tourism students in Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. There are 30 students enrolled in English 2 in the second semester of academic year 2013. The instruments used in this study were 1) to practice listening and speaking English skills 2) achievement test listening and speaking English. The data were analyzed by percentage. The results showed that the attitude of the students towards self-access computer multimedia practice in listening and speaking English skills. Overall found the average level of attitudes that influence decision making was good in 87.6%. After using the multimedia computer program students have well 84.71% in listening and the attitude of the students towards computer multimedia speaking was good in 85.23%.

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.

This research is to develop a prototype of a salinity intrusion monitoring system using fuzzy logic to extract salinity values. A system is developed according to a fuzzy logic model using FAOs for appropriate agricultural water quality data considering the electrical conductivity (EC) and total dissolved solids (TDS) as indicators of the salinity value by using the Fuzzy Logic Toolbox to produce and test the generated model. Transformation of the generated models to Embedded C format using the Simulink Coder tool installed in the ARM STM32F microcontroller and a 10-fold cross-validation test was used to validate the data extraction. The Root Mean Square Error (RMSE) for the test results was 0.58175 on average. This research result indicates that the generated model is able to extract data that very closely matches the specified data.
