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 %.

This research uses quantitative research regulations for its purpose of 1) To study the trend of Potential development and career development in textiles and fashion . 2) The development of short-term courses in textiles and fashion it is suitable for the needs of entrepreneurs and the general public. 3) To guide for organizing short-term courses effective in textiles and fashion for making money to the university. Is focusing on the development of short-term course of textiles industry and fashion. There are 2 sample groups Such as entrepreneurs and workers in textiles and fashion industry. The instrument used in the study are questionnaires requirements for the development of textiles industrial and fashion personnel. The aim for study is respondents information training needs to develop the potential of textiles and fashion personnel and the factors influencing the selection of the service short-term course.
