Were selected by random selection of 30 people. The study found that the Development e-learning for history primary 4. The media satisfaction is at a high level.

The research projects of Development of Thai Silk Scrap of “Panpum” by Thai Painting Technique. The purpose is as follow. 1) To study the product development process Thai Silk Scrap of “Panpum” . 2) To study the satisfaction of the target group on the product Thai Silk Scrap of “Panpum” . The results revealed that 1) The experts from 5 person commented that Development of Thai Silk Scrap of “panpum” by Thai Painting Technic from the sewing. It can be used in the field home economics for 3 persons but it can’t be used for 2 persons because the silk scrap was quite high Prices and also famous. Later Experts 4 persons give opinion that can development but 1 person give opinion that can not development because writing may not be clear. In writing Thai motifs on a piece of silk to be a variety of petals. 5 experts give opinion that was a conservation invention. Finally 5 experts give opinion that patterns were appropriation to make development. They don’t need more patterns. 2. Satisfaction of target group Thai Traditional of “Panpum” When considering each found as following. Creative was high satisfaction with average 4.23 . Appropriate was high satisfaction with average 4.13 Beauty was high satisfaction with average 4.11 color tone was high satisfaction with average 4.05 General shape of the Thai traditional “panpum” was high satisfaction with average 4.02 . And design was high satisfaction with average 3.66. Overall consideration was highest with average 4.84 “Thong noy” Tray with pedestal. When consideration each topic found as following. Appropriation was high satisfaction with average 4.56. Beauty was high satisfaction with average 4.43. Color tone was high satisfaction with average 4.30 . General shape of “Thong noy” Tray with pedestal high satisfaction with average 4.26. Create was high satisfaction with average 4.25. Design was high satisfaction with average 4.12. Overall consideration was high satisfaction with average 4.30

The purpose of this research is to develop a hot air dryer using waste heat from a200 liter kiln for drying bananas and to investigate its drying performance. The main parts of the dryer consist of the drying chamber that has dimensions 0.71x0.83x.091 m3 the air circulation system and a heat exchanger which receives waste heat from the exhaust tube and kiln surface. The dryer was developed by designing a drying chamber on the top of a 200 liter kiln to reduce heat lost in the structure and an exhaust gas heat exchanger was developed using groups of copper tubes for increasing then heat transferred to the air. The drying performances were analyzed by measuring specific drying rates and specific energy consumption. Experiments were performed under different temperatures of 60 70 and 80℃ And at a constant velocity of 1.8 ms-1. Eucalyptus was selected as the heat source. Thirty kg of peeled bananas were prepared at an initial moisture content of 241.19±31.50% dry basis and were dried until to final moisture content of 48.47±10.46% dry basis. All experiments were carried out in duplicate. For temperatures of 60 70 and 80 ℃ the ave age specific drying rates were 0.085±0.0004 0.114±0.0009 and 0.1277±0.010 kg water h-1kesolid-1 and the average specific energy consumptions were 1.42±0.055 1.21±0.355 and 1.04±0.074 MJ/kg water respectively. Some dried bananas had burned at a temperature of 80℃ so at temperature of 70 ℃ was the optimal condition in this experiment. This produced good color a high specific drying rate and low specific energy consumption.

This study explored batik cotton coated by stabilizing substance made of three kinds of plant and animal including gum arabic powdered gelatin and carboxymethyl cellulose or CMC at a ratio of 15 grams of stabilizer per 3300 ml. of water. The stickiness was tested using the electron microscope SEMScaning able to be 1000 times enlarged and Shirley Stiffness Tester was used to test for the stiffness to measure the bending length of the fabric. It was found that the gelatin from animals could coat the surface the best. The fabric bending length demonstrated the average warp yarn of 4.78 cm and weft yarn of 4.92 cm. Subsequently the fragrance was added with 25 ml of micro-capsules and bound with 10 ml binder per 1000 ml water. After leaving that for one day and 30 days the amount of microcapsules attached to the fabric was investigated. It was found that the microcapsules of powdered gelatin stack on the batik cotton the most followed by gum arabic and carboxymethyl cellulose or CMC respectively. The fabric bending length of warp yarn was 5 .8 2 and weft yarn was 4 .7 0 . Concerning the washing endurance for one two or three times itสถาบันอุดมศึกษา was found that the microcapsules stack on batik cotton coated by powdered gelatin the most followed by gum arabic and carboxymethyl cellulose or CMC respectively. Therefore the batik coated with powdered gelatin was considered suitable for the production of flowered garlands and flower crafts as special occasion gifts. Also the knowledge could be transferred to the professional arts cooperative groups in Nonthaburi. The results of the training were satisfying revealing the average satisfaction towards officers’ service at 4.87 speakers or trainers at 4.87 procedures at 4 .8 0 facilities at 4 .8 6 benefits at 4 .82 and average satisfaction in the overall at 4 .9 3 . The participants were highly satisfied at 98.00% and 100.00% for the application.
