This study was to 1) investigate the using behavior on the road accessories in the park and 2) analyze the design guideline for the product consistent with the use of leisure space in passive way 3) synthesize the design guideline to for the product consistent with the use of leisure space in passive way to response city life and 4) to find solutions to the problems of sustainable use of public space. The conclusion of the data analysis by using questionnaires from residents in the sample area found that; 1) Respondents were 130 men or 43.4% and 170 women or 56.6% 2) the highest average score was from 94 respondents age 31-40 years old or 31.4% 78 respondents age 21-30 years old or 26% 3) 116 respondents or 38.7% were company staffs with the highest score followed with 89 students or 29.7 and 4) 4 respondents or 8.89% who have live less than 20 years 14 respondents or 13.11% age 21-30 years old 12 respondents or 26.67% age 31-40 years old and 15 respondents or 33.33% for age 41 years old up 5) 98 respondents or 32.6% spend time in the park 1-2 times a week 94 respondents or 31.3% 6) 142 respondents or 47.3% for the reason of relaxing in the park- quiet and followed with easy to access 121 respondents or 40.3% and lastly 7) the activities in the park is relaxing 141 respondents or 47%.For design the research design from data analysis and experts. It shows that 1) the main structure is steel tube and nylon product and 2) concept design was from nest and cradle. The feature of the product is like the weaverbirdnest and the cradle gives personal area.
การออกแบบเครื่องทอผ้าแบบ 2 กระสวยด้วยเครื่องแจ็คการ์ด (JACQUARD) เพื่อพัฒนาผ้ายกดอกเมืองนครตามแนวคิดเศรษฐกิจสร้างสรรค์
This research was the design of two shuttles loom with Jacquard to develop the Nakhon District embossed fabric according to creative economy model. The objectives were to design and develop efficiency embossed loom. These researches were six steps as following: 1) study to embossed woven fabric production process with traditional loom by studying embossed woven with labors duration was related with the complicate embossed woven fabric process and the embossed woven techniques related with the woven pattern. 2) Took the data to apply for the design and development two shuttles loom with Jacquard by 2 shuttles loom prototype product to test and experiment in 1 loom. 3) Took 2 shuttles loom with a Jacquard (JACQUARD) prototype to develop the Nakhon embossed fabric transferred the knowledge to the wisdom and disseminate how to use 2 shuttles loom for the embossed woven group of Kanok Silp Nakhon weaving community enterprise at Tambon Bankhonhat Cha-uat district Nakhonsrithammarat province. 4) Produced the fabrics by holding the flake Borneo camphor striped embossed woven with cone-shaped and the Phikun striped embossed woven with cone-shaped. 5) Compare the embossed woven fabric process between two shuttles loom with Jacquard and traditional loom with the same pattern in the Nakhon embossed woven group of Arts and Crafts Center Ban Trokkhae Cha-oud District Nakhonsri- thammarat province. 6) Took the embossed woven fabric 2 shuttles loom with Jacquard by using community product standards testing. The result of studying the embossed woven fabric with two shuttles loom with Jacquard (JAQUARD) was the mechanism of weaving found that woven fabrics with 2 shuttles loom with Jacquard (JAQUARD) could reduce various problems. Those were: 1) Reduced 3 labors including the weaver to lift a horn or heddle while the embossed woven fabric 2 shuttles loom with the Jacquard (JACQUARD) could only one weaver control to lift it. 2) Reduce the time spent on weaving 3-5 times when compared the number lengths of woven fabric in the same width. 3) Reduced the woven fabric process problem include 2 shuttles loom could weave continuously and could change woven patterns quickly without lift the loop or keep it again. It was also added a technique to weave with gold or silver yarn to switch back and forth which did not change the shuttle using applied techniques from the loom were adapted to use in a jacquard. The result of the test based on the community product standards testing. It found that the embossed woven fabric of the weaving community group woven Kanoksinnakorn fabric through the criteria of the community product standards testing in 6 ways. Those were general way identity way the durability of washing way the color fastness and perspiration way the change in size after 1 wash way and acidity and alkalinity way.

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.

Arduino microcontrollers are used to control the system. By starting the study of the air conditioning system thoroughly. The microcontroller is written to control the operation of devices like the air conditioning system when the system malfunction. It will be used to analyze the problems of air conditioning. The experimental set will display the voltage and current. The connection points of the air conditioning problem analysis. When the symptoms are bad. The analyst can solve the problem by connecting or pressing the button of the device. The results of the project. The test will measure the difference of the air conditioning unit. And read the amount of current and volume in the system.
