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.

: The purpose of this project is wale laying and make cosplay costumes using Thai woven fabrics. To study the satisfaction with the cosplay costumes that are sewn with Thai woven fabrics to study about how to produce cosplay costumes with Thai woven fabrics.to study the wale and the pattern from those and satisfaction survey in both times the first is the sample survey about wale laying on the pattern by 300 people buy online. Tools include The Disney Princess Cosplay Costume wale laying with Praewa pattern and Pikul flower pattern 4 sets and the second satisfaction survey is the satisfaction for those who cosplay at the JAPAN EXPO THAILAND event 2019 at Central World tools include Princess Cinderella Cosplay Costume that is sewn with Thai fabric Praewa pattern and Princess Jasmine cosplay costume which is sewn with Thai fabric Pikul flower pattern and satisfaction survey by 100 people. Statistics used to describe the results of data analysis in project work Use percentage pie chart and average. The result of the development of the cosplay costume style with Thai woven fabric was found that the cosplay costumes were cut by 4 patterns of Thai woven fabrics. The opinions from the groups who were interested in the majority of opinions were very beautiful. The design fits well with the set. Wanting to make more dresses and applying Thai fabrics is a good idea. Because Thai people now start to wear less Thai fabrics. The 1st evaluation results the development of a cosplay costume style with Thai woven fabrics by wale laying Found that each set was satisfied with the average score as Jasmine Princess Dress wale laying with Pikul flower pattern wale laying with Pikul flower pattern Received 28% Princess Jasmine wale laying with Praewa pattern Received 27.7% Princess Cinderella wale laying with Praewa pattern Received 27.3%. Princess Cinderella wale laying with Pikul flower pattern Received 17% Summary of opinions about the wale laying of princess dresses found that the two jasmine princess dresses are the most popular. But the selection of the set to create the second satisfaction survey selected the most popular princess dress by using the selection by choosing Princess Cinderella to dress The sewing is with Praewa woven fabric and Princess Jasmine with Pikul woven fabric The result of the second evaluation the development of a cosplay costume pattern with Thai woven fabric by sewing found that each set was satisfied by being able to average score as follows. Princess Cinderella dress with Praewa woven fabric has received 51%. Princess Jasmine with Pikul woven fabric has received 49% Summary of opinions about the sewing of a cosplay costume with Thai woven fabric Princess Cinderella dress The sewing is made with Praewa woven fabric the most popular because it is the beauty of the Praewa on the fabric that is sewn to make it exciting for every people to get the highest score

Milk and milk products are complex foods which do not drink late at night but there are conflicts that cause confusion about milk milk products and drinking beverages which have some milk should or should not consume. This research was aims to make a manual preparation about drinks for the monks which focus on milk and milk products for give the data and detail of raw material ingredients process. From the results found that the Forest monastery (Wat Pah) has the strict laws and statutes more than the temple (normal monastery) by the rules such as: the Buddha commanded by the discipline sect duration time types of raw material ingredients process and other depends on the policy for each temple. Therefore the monk and temple boy must study very well about information and nutrition facts or food processing.

Epoxy is one type of materials for adhesive. It was improved the strength by adding the filler such as iron alumina or silica. Generally the epoxy adhesive was mixed with iron for application in the metal adhesive. The mechanical properties were importance of adhesive. Because it was one factor for lifetime limit. The iron/epoxy was casted in the magnetic field which was alignment with surface of samples. The alignment of iron particles was induced with magnetic fields. The mechanical properties and wear behavior of samples were investigated hardness and wear test. It was found that the alignment of iron particles in the epoxy were improves hardness and wear.
