This research aims to develop the coconut coir ceiling board mixed with natural latex. The 6 ratios of gypsum plaster: coconut coir: sodium silicate: natural rubber: tap water are equal to 1: 0.15: 0.03: 0.00: 1 1: 0.15: 0.03: 0.01: 1 1: 0.15: 0.03: 0.02: 1 1: 0.15: 0.03: 0.03: 1 1: 0.15: 0.03: 0.04: 1 and 1: 0.15: 0.03: 0.05: 1 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of coconut coir ceiling board mixed with natural latex followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density thermal conductivity coefficient and real usage. From the results 1: 0.15: 0.03: 0.03: 1 ratio is the most suitable ratio of coconut coir ceiling board mixed with natural latex. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products.

The purposes of the research were to 1) study the attributes of the graduates according to standards of learning outcome 2) study the 21st century skills of English for International Communication graduates desired by employers 3) compare the attributes of the graduates according to standards of learning outcome categorized by the individual factors and 4) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The population were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews which were analyzed by the SPSS program. The statistical data analysis was performed by frequency percentage mean standard deviation and Fdistribution and the interview data analysis was performed by frequency and content analysis. The results were found as follows. 1. As for the employers information33emoloyets were from private and service businesses (60%) and 14 employets were from government sectors (25.50%).As for the working statuses29 employers were the officers (53.70%) 20 employer were the supervisors (37.00%) and 5 employers weie mangers (9.30%) 2. The overall requirement of hte employers for the attrbutes of the graduates according to standandards of learning outcome was at the high level (=4.48). As for each attribute morals and ethcs were the most desirable (=4.75) the second highest level was interpersonal skils and accountabiliy (4.57) and the last one was the intellectual skills (=4.25) 3. The overall requirement of the ernptoyers for the 21st century skills of the graduates was at the high level (=4.43). As for each attribute the highest level was enthusiasm collaboration and thinking skills respectivrty (=4.634.58 and 4.54) The lowest tevel was the inquiry skills (=4.07). 4.The results of the research hypothesis were; 4.1 There was a significant difference between the employers with different employrment sectors (government and service business sectors) and the requirement of the graduates attributes. There was no significant difference between the employers with different working status and the requirement of the graduates attributes. 4.2 There is no significant difference between the employers with diferent employent sectors and working status and the requirement of the graduates attributes.

The purposes this research were: 1) to develop the activity packages on home textile pillow products forming process for textile product design students division the efficiency of 80/80 2) to compare academic achievement of textile product design students academic calendar 2018 before and after the experiment using the activity packages on home textile pillow products forming process 3) to study satisfaction of students toward the activity packages on home textile pillow products forming process. The sample consisted of 20 students who studied textile product design in the academic year 2018 at Rajamangala University of Technology Phra Nakhon. They were selected by purposive sampling. The research instruments were the activity packages on home textile pillow products forming process the achievement test and a satisfaction questionnaire. The data were analyzed by percentage mean standard deviation and t-test for dependent samples.The results of the study were as follows: 1) the efficiency of the activity packages on home textile pillow products forming process for textile product design students was obtained 84.65/82.50 higher than a predetermined threshold 80/80 2) academic achievement of home textile pillow products forming process for textile product design students was significantly higher than before the experiment using the activity packages on home textile pillow products forming process at the 0.5 level 3) the satisfaction of Textile Product Design students using the activity packages on home textile pillow products forming process was at the high level.

On Earth all objects have a weight which Earths mass exerts on them to downward force of gravity. The weight of an object can find somethings weights in Newton unite. It calculated on multiply the mass in kilograms by the acceleration of gravity in the units of meters/seconds2. The purpose of this study was to design and develop an experimental setup for measuring the gravity acceleration. It involved designing by using free-fall motion method in vacuum tube based on digital Technology and photo gate sensor measured the velocity of the ball object. The data were analyzed by Microsoft Excel. The value of gravity acceleration obtained at 9.617 m/s2 from the experiment set up. The value from the experiment was compared with the obtained from true value at Bangkok Thailand. It found the error at 1.697 %. The assessment of the quality used a questionnaire for data collection. Five content experts in Physics teaching evaluated it. That found mean 4.89. The results of the study revealed that the experimental set up were excellent quality of and high efficiency. So that this experiment suitable to be used in physics classroom.

This research is aimed to develop the Electronic Journal Database Management System: Case Study – Academic Journal and Research of Humanities and Social Sciences Rajamangala University of Technology Phra Nakhon. By developing the online database website we will be able to use this to transfer the information review the articles gather information publish the knowledge and innovation from the study research and encourage University’s officers to have the channel to publish their academic journals and Humanities and Social Sciences research. Also this can be used to publish and announce the news via Internet network and use it as a search engine for anyone who is interested in the journals and researches which can be lecturers students or general public. The method for system development started with the system design and get tested by the specialist. After that the system has been experimented with the sample group of Research and Development section officers and researchers and received the report. The system result information has been displayed via website which is developed using PHP MySQL Dreamweaver and Photoshop The results of Electronic Journal Database Management System development : Case Study – Academic Journal and Research of Humanities and Social Sciences Rajamangala University of Technology Phra Nakhon are based on the sample group who are University’s lecturers and officers. The sample group tested the system by searching for the information in the system. The results indicated that the information was filled in from the sample group and displayed correctly.
