The summary of females living in Bangkok was as follows: results from the research shows that out of the 400 participants a large proportion were aged between 23 - 30 year’s old who held a Bachelor’s degree and worked in private sector earning approximately between 10000 to 18000 THB per month. If purchased through a sales person a customer has the privilege to compare products and make informed decision. Also if products are on sale the customer may buy extra items and pay at the counter (otherwise it is purchased through online stores for example: Lazada).

This research was aimed to study the high temperature degradation of AISI 1020 carbon steel pipe under the carburizing atmosphere. This environment was prepared by a mix of powdered charcoal and CaCO3 catalysts and then simulated at temperature of 1000C for 1 2 and 4 hours. The variation in the weight of the aged steel specimens was obtained by the measured metal loss at various working periods. The light optical microscope was used to observe the microstructural changes of aged steel samples. The results revealed that the prolonged operating period decreases the weight of samples and the degradation occurs on the outer surface of the pipes. The study also indicated the microstructural difference between the inner and outer wall of the steel pipe which is resulted from the changes in chemical compositions during the carburizing process.

The objective of this research is to reduce waste in the production ceramics of Dadear Ceramics Factory in Lampang Province. The 7 quality control tools (7 QC Tools) were implemented including Check sheet Graph Pareto diagram and Fishbone diagram were used in analyze problem and solve the problems. It was found that most of the wastes come from burning ceramics process. The kilns and wheelbarrow has been used for a long time furthermore the equipment and parts were damaged from lack of maintenance. The non-standard of product arrangement method into the furnace were the cause of waste. Thus the researcher were improve wheelbarrow into the kilns and design a fixture to help worker to product arrangement. The results of the research which geathering data from quality inspection department. Then comparing data before the improvement (between September to December 2013) and after the improvement (between November 2014 to February 2015) the wastes are reduced from 8.97% to 0.29%.
