The objectives of this special project were to product travel documentary of the National Museum in Suphan Buri Province and study of the satisfaction of thevisitors from 200 tourisms by using the questionnaire. The statistics to analyze data was frequency percentage average and standard deviation (S.D.) The result shown that the tourisms had high levels of satisfaction to the travel documentary of National Museum Suphan Buri Province.

This special project aimed to develop art book Thai fantasy and evaluate the satisfaction of viewers to art books Thai fantasy. The data collected from 50 people who was interest Thai arts and Thai cultural. The statistic to analyze was frequency percentage mean and standard deviation. The results showed that the target group was satisfied with the art of Thai fantasy at the highest level. (𝒙̅=4.54 S.D.=0.50)

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.

The objective of this work is to investigate the effects of water injection on performance of 5-stroke SI engine converted from the conventional 4-stroke SI engine.The cylinder head of the 2ndand3rd cylinder was modified and connected to each other to be the ultra-expansion stroke or second expansion stroke (5thstroke). The engine was performed on a dynamometer at different engine speeds and loads of 1500 to 3000 rpm and 25% to 75% of full load respectively. The water was injected during the second expansion stroke (5th stroke). Fuel and air consumptions engine torque rotational speed air/fuel ratio and temperatures of intake air engine oil cooling water and exhaust gas were recorded to use for calculating brake specific water and exhaust gas were recorded to use for calculating brake specific fuel consumption (BSFC) and engine efficiency. The results showed that at low engine speed of 1500 rpm for all loads the water injection improves BSFC and the engine efficiency by 26% and 3.3% respectively. However a large amount of injected water shows insignificant improvement on BSFC and the engine efficiency due to short residence time especially at high engine speed. The deterioration of engine oil can be observed after test. These findings are relevant to engine design or modification especially at low engine speed.

The Research Projects of Production of Deodorizing Charcoals from Mangrove Charcoal : an Applied Local Wisdom of “Pleakmai Group” at Baan Khaoyeesarn Amphawa district Samutsongkarm Province. The objective is as follows. 1) Design and development of charcoal deodorizing from mangrove charcoal. 2) To pass on knowledge of the invention of deodorize charcoal ones. The results revealed that 1. 5 experts answer Questionnaire about the model of charcoals derived from mangrove. Most of souvenir were chosen by expert are deodorizing pillow deodorizing cactus pot and deodorizing key chain. Most of home decoration product are deodorizing mobile deodorizing tissue box and deodorizing picture frame. 2. The target group questionnaire satisfaction was as follows. Course with satisfaction The Research Projects of Production of Deodorizing Charcoals from Mangrove Charcoal : an Applied Local Wisdom of “Pleakmai Group” at Baan Khaoyeesarn Amphawa district Samutsongkarm Province. Consider each objective found. The objective of the research project was accord with demand of the community was the highest level with average 4.82. Accord with the needs of the trainees and up-to-date content of the curriculum with average was 4.8. Overall consideration was found highest satisfaction average was 4.71 with standard deviation 0.60. Satisfaction with the research project of Production of Deodorizing Charcoals from Mangrove Charcoal : an Applied Local Wisdom of “Pleakmai Group” at Baan Khaoyeesarn Amphawa district Samut songkarm Province. When considering each topic That was found as following. In the service processing the project team were prepared and also concentrate to good service 4.82 Secondly the lecturers had the highest level of expertise and also knowledge in the content was training with an average of 4.80. Satisfaction was at the highest level. The mean was 4.67 standard deviation was 0.82. Satisfaction of product The Research Projects of Production of Deodorizing Charcoals derived from Mangrove : an Applied Local Wisdom OF “Pleakmai Group” at Baan Khaoyeesarn Amphawa district Samutsongkarm Province as following.
