The research aims to 1) promote historic and cultural tourism at royal temples in Ayutthaya province; and to 2) identify ways of promoting cultural tourism sustainably. The research methodology is mixed-method. The quantitative data was collected from approximately 400 Thai tourists by means of questionnaires. The qualitative data was collected by means of interviews with 8 tourism stakeholders in Ayutthaya province. Data were analyzed to identify the frequency percentage mean (x̅) and standard deviation (S.D.) using SPSS. The research found that Thai tourists and tourism stakeholders support measures to develop Royal temples in Ayutthaya including: 1)Wat Phra Sri San Phet; 2) Wat Panan Cheng Worawiharn; 3) Wat Na Phra Maen; 4) Wat Kasattra Thirat; and 5) Wat Phrom Niwat. In order to develop this royal temples there should be co-operation between locals and the private sector to promote sustainable tourism and to preserve the beautiful heritage sites as world heritage sites. The private sector and locals should support sustainable tourism activities and Thai culture to attract tourists who can encourage socio-economic development. In addition tourism facilities should be developed such as tourism landscapes parking areas tourism information public toilets and facilities for the elderly and disabled. Tourism policy should be supported through co-operation between locals and tourism stakeholders. Tourism management authorities and locals should support activities to preserve culture in order to attract more tourists and increase tourism revenue.

Milk one of the favorite food around the world typically is produced by the mammary glands of mammals such as a cow. However dairy from the cow is not suitable for people with dairy allergies and lactose intolerance. Thus the global demand for non-diary or plant-based milk is rising. Sacha Inchi (Plukenetia Volubilis L) or Dao incha is an edible oil-seed nut originated from the Amazon Rainforest in Peru. This crop is known as a rich source of oil with high content of polyunsaturated fatty acids. Not only essential fatty acids but the nuts also consist of high protein level and minerals. It is not surprising that in recent years there has been growing interest in developing the sacha inchi plant as a novel food such as roasted nuts or cookie. This study evaluated the chemical physical microbiological properties and nutritional factor of milk from Sacha Inchi comparing with pressed-cake powder from a by-product of Sacha Inch oil extraction process. According to our results the Sacha Inchi has a potential to be developed as an alternative plant-based milk. The roasted Sacha Inchi milk consists of a complete protein with all nine essential amino acids and they are rich in omega 3 6 and 9. A high contents of minerals such as 2400 mg of calcium per 100 g sample was aslo found in raosted Sacha Inchi nuts. By roasting the nut the protein content was found to be decreasing up to 55.34 % to the same level of the protein content in the pressed-caked Sacha inchi powder. However roasting can add a flavor to the Inchi nuts and also in the milk. Comparing the nutrition factors of the nut milk and the pressed-cake Sacha Inchi milk the pressed-cake milk consists of fat and calory less than roasted Sacha Inchi milk. However the protein and sodium content is quite similar at 4% and 15 mg respectively. The preference for original matcha green tea and cocoa of the roasted Sacha Inchi milk were determined. The three samples were not significantly different in the liking of any attributes (p>0.05). The color of the three flavour of non-diary milk showed slight to moderate in customer liking. Although not significantly different in affection the cocoa flavor had higher liking scores than original and green tea flavors. The just-about-right results showed that the disliking of Sacha inchi milk was mainly due to too much bean aroma and flavour as well as too less sweet taste. The Dao Inca milk has the potential to be new high protein milk that is good for health-conscious consumers and those who are allergic to cows 3 milk. The current product was not well liked due to intense beany aroma and flavor and too less sweet taste. However using other flavours and seasoning such as cocoa could mask the beany smell and flavour.

The purpose of this research is to design and develop dummy (anthropometric test dummy) for motorcycle frontal collision test. The conceptual design of dummy is male aging between 25-55 years old 6 pieces of rib and deformable 76.2 mm. In order to performance test it was classified into 2 testing by static testing and dynamic testing. For static testing the energy absorption behavior between force and deflection or “ static curves” is determined. While dynamic testing is considered to the energy absorption behavior between forces and several velocities or dynamic forcedeformation curves impact acceleration impact force on sternum and injury severity with the relationship of viscous in velocity function. The results of the energy absorption behavior on chest of dummy from static testing the tendency of chest deflection is relatively low during the initial force and suddenly increasing when rise to the critical point. This behavior is similar to the energy absorption of the human chest. Therefore the design features of this test dummy can reflect behavior that is close to the human anatomy. In case of dynamic testing it is discovered the ability of the dummy testing to absorb up to 560 J impact acceleration 3 8 . 4 3 g impact force on sternum 5 . 0 9 4 kN. The viscous in velocity function is 0 . 8 2 5 m/ s which compared to injury severity at AIS3+ ( or higher than serious injury) . Therefore the dummy design in this research project corresponds to the collision test of a motorcycle.

A design and development of powertrain module crash test using with the motorcycle crash test is aim to create a special tool for automotive assessment and safety engineering based on the realistic test. In order to main system of power module tester is consisting of powertrain system using electrical motor transferring system using chains and gears and control direction system using dual rails respectively. Based on powertrain module tester performance crashing speed relative angle between target and distance before crash are regarded. Nevertheless the result of testing performance was conducted to statistic hypothesis test by Mean Absolute Deviation: MAD Standard Deviation: SD Mean Square Error: MSE Mean Absolute Percent Error: MAPE and Root Mean Square Error: RMSE. The results of this approach discovered that the crashing speed was the highest error with 96% and the lowest was distance before crash. Furthermore it was corresponding to the statistic hypothesis test. However the result of the error was influence of the rails distance which limit by funding. In case of crash energy the mean of energy was appeared on 10.978 J. Whereas the tendency of variable was similar to polynomial equation.

The development of lightweight flat sheet prototype from para rubber leaves and para para rubber wood fly ash for field work application can offer an alternative method of adding value to agricultural wastes and help to conserve the environment with green products. The natural fiber especially agricultural waste fiber is an encouraging prospect. Natural fiber composites have been used for building applications. The aim of this research was to investigate the potential use of para wood ash to producing a cement composite as an environmentally material. Material. The cement paste with 5-2 % weight of para wood ash. The specimens were cured at 25± 2 oc for 24 hours. The properties of cement composites mixed with different proportions of para wood ash were compared with Ordinary Portland Cement (OPC). In addition the morphology of para wood ash was examined by using scanning electron microscope. The density increased with the increase in the percentage of para rubber leaves from 1% 2% 4% and 6%. The finding is attributable to the enhanced packing density by the fine para wood ash particles size was found 5-10 um.Moreover para wood ash particles could arrange to fill the inter-particle voids in cement pastes which resulting to increase the compressive strength of cement paste. Consequently para wood ashes could incorporate in the construction materials to enhance the mechanical properties and durability performance of the cement composites
