The objectives of the research were 1) to study marketing communications buying behavior and buying decision of consumers Tesco Lotus in Bangkok 2) to compare demographic characteristics with buying decision of consumers 3) to compare buying behavior with buying decision of consumers and 4) to study marketing communications effect buying decision of Tesco Lotus of consumers in Bangkok. The sample group consisted of 400 consumers at Tesco Lotus. The research instrument was a questionnaire. The statistics from the research were frequency percentage mean standard deviation and Multiple Regression Analysis. Statistical significance level was set .05.The study presented the following results: 1) marketing communication was in high levels consisted of public relations promotion and personal selling 2) the most buying behavior of consumers: lower one a week buying in Saturday and Sunday 18.01-22.00 p.m. buying in supermarket media exposure from television broadcasting buying decision of advertising media 5011000 bath buying and buying for use 3) buying decision of consumers’ Tesco Lotus was in high level including product location and price 4) different age and education had differences on their buying decision of consumers’ Tesco Lotus 5) different buying behavior had differences on their buying decision of consumers’ Tesco Lotus and 6) marketing communications affected buying decision of Tesco Lotus of consumers in Bangkok included public relations promotion and personal selling.

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%. The result of improving is very efficiency because it can reduce the wastes to 8.68%.

This study was carried out to evaluate the influence of pruning on floral emergence fruiting yield and fruit quality in longan. Fifteen years old “Daw” longan trees were pruned in June 2013 at Agricultural Technology Research Institute Rajamangala University of Technology Lanna Lampang province. The longan pruning for removing some branches consisted of 4 treatments i.e. 25 50 and 75 % compared with no pruning. The result revealed that there was no effect of treatment on floral emergence or leaf flushing after potassium chlorate application. However the 25-75 % pruning gave greater new shoot length leaf width and leaf greenness than that of no pruning. The pruning treatments increased fruit size while the highest pruning (75 %) decreased yield and the no pruning produced the lowest yield.

This research was aimed to study the effect of chitosan on total polyphenol contents anthocyanin contents antiradical properties and resistance of rice blast disease in Sung Yod Phatthalung rice (Oryza sativar L.) cultivars. The chitosan was applied on rice leaves at concentrations of 50 100 and 500 ppm compared with the control (without the chitosan and only adding a 0.025% acetic acid respectively). The result showed that 500 ppm of chitosan could significantly increase the total polyphenol contents (220.75 mg GAE/100 g dry weight sample) anthocyanin contents (2.98 mg/100 g dry weight sample) and antiradical properties (83.15%) in the grain extracts of Sung Yod Phatthalung rice. In addition Necrosis test on rice leaves treated with 500 ppm of chitosans clearly indicated the plant resistance againt Pyricularia grisea. Therefore the future studies of chitosan activation mechanism will give more valuable information that possible to be applied in the healthy rice product development and fungal disease control.

The purpose of this research was to investigate cooling water profile that effect to coefficient of performance of spilt type air- conditioning system. Air conditioner size of 12000 Btu/h was used in this experiment. There are three experiment of cooling water profiles in this work such as water spray water drop and heat exchanger profile. The ambient temperature conditions were controlled at 35 40 43 and 45 oC. The results of this study were found that heat exchanger profile had the highest average coefficient of performance and energy efficiency as 4.94 and 9.15 Btu/Wh which increased as 20.1% and 8.47% respectively when comparing with the normal working.
