This research aimed to this research aim: 1) to study the problems of the National Museums in Central Region of Thailand 2) to study The Guidelines of Marketing Development of Arts and Sciences Educational Attraction of the National Museums in Central Region of Thailand. This research is qualitative research with interviews. The researchers also studied theories involved from documents includes Marketing Mix (7P’s). The sample group used in this study is the officers involved in the Central National Museum. The tools used in this research are interviews. This research found that Products and services the three national museums products or antiques Is interesting and distinguished in itself. Service characteristics of the museum focus on providing educational services providing information to interested parties. The price of collecting admission fees and using the premises according to the regulations of the Fine Arts Department. Location convenient transportation both private cars and public transport. Marketing promotion there are books brochures brochures and information systems through computer networks. Personnel or employees there are good work intentions good service smiling. Physical environment the building is quite old. It should improve modern display techniques. Processes Group visits are usually contacted in advance in order to arrange a guest speaker. Suggestions for museum development Products and services should consider the enjoyment of the visitors learning including receiving details of meaningful signs. Location adding a sign showing a large museum entrance. Marketing promotion should advertise through various online media should organize creative learning activities. Physical environment should improve modern display techniques. Processes adding a tourist center help to inform visitors of the rules and regulations for visiting museums for proper conduct.

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 purpose of this research was to study productivity rate in concrete plastering of interior brick wall by studying 2 construction projects in Bangkok. The researcher divided the methods of labor productivity into two categories: (1) direct labor production technique and (2) field rating technique. The direct labor productivity technique of project A is about 1.38 m2/person/hr. and project B is about 1.19 m2/person/hr. by field rating technique project A had 77.75 % of workers in work status project B had 73.75% of workers in work status. The error rate was 4.08 % and 4.31 % respectively at the 95% confidence level. Project A has higher productivity rate than project B because project manager A chooses ready-mixed plaster for plastering. Project B selects cement mix (silica cement) mixed with fine sand cement mixer and water which take longer to prepare than Project A resulted cost of materials increase for 28.21 %.Meanwhile the working time for wall plastering could take longer for 13.77 %. It can be concluded that the selection of material for work is another factor affecting labor productivity

Currently the automotive industry plays an important role on the economic growth in Thailand. As the same time the waste of automotive parts has increased as well. As a results the automotive parts made from three different natural fiber parts was studied consisting of hyacinths sugarcane and pineapple leaf fiber. By of 50 x 250 x 20 mm of mold dimension the specimens were produced under 700 W of heating stick and measured temperature by a K type of thermometer. There were 3 same proportion specimens made from: 1) sugar cane fiber: husk: latex adhesive 2) water hyacinth fiber: husk: latex adhesive 3) pineapple fiber: husk: latex adhesive in the ratio of 25:25:50 by weight which were formed under temperature between 100GC and 105°C at 5 MPa of pressure and leading to find out the bending moment ability. The test results show that the specimen made from sugar cane fiber has the highest value 5482.5 Nand 4061.11 N/mm2 of bending moment and bending stress respectively. It was more than specimen made of water hyacinth 29.84 % and pineapple fiber 65.01 %.
