This research studies the wisdom crafts in Central using vetiver grass is the main material designed by researchers studied weaving in combination with cutting new product development which can take as a model to develop products accordingly. the project is the initiative of his Majesty the King. The study forms the products from grass found from interviews with design professionals. Concluded in the production and design of the model the researchers examined the experts as appropriate. The researcher has taken the form of furniture decorative home modifications. Manufacturers can actually formed. Survey forms about home furnishing 30 which follows. The front living An average of 4.6 more convenience average of 4.6 more security average is 4.75 the design average of 4.7 more overall satisfaction is at the highest level

แนวคิดการสร้างมูลค่าเพิ่มของบรรจุภัณฑ์จากเศษวัสดุเหลือใช้  ภายใต้แนวคิดเศรษฐกิจสร้างสรรค์
แนวคิดการสร้างมูลค่าเพิ่มของบรรจุภัณฑ์จากเศษวัสดุเหลือใช้ ภายใต้แนวคิดเศรษฐกิจสร้างสรรค์

This research aims (1) to study the added value of the package of leftover concept of the creative economy (2) the concept of packaging designers from residues that can affect the attitude of consumers (3. ) to analyze the development trend of packaging residues. The samples used in research The research sample was divided into two groups. The first sample packaging designers from the establishment of private companies and industrial packaging and printing 20. The samples of two academic staff at the university. And design professionals in the packaging industry and related government agencies. The study concluded that: 1) study the need packaging that require packaging to protect the product from damage. Unique and engaging. 2) to design and develop a packaging structure. Not to damage prevention. Attraction and unique.

Brake system is used the friction between disk and pads. In the driving conditions the brake behavior from the driver is difference. Based on this reason the damage on disk and pads are occurring. Nowadays the ratio of compound materials in pads is several and involved automotive industry has not available enough to experiment. Thus it is difficult to brake pads damaged analyzing in several driving conditions. In this problem the mechanical property tester is main tool for experimenting. And test procedure based on the Brake lining and disc brake pads compressibility JIS D 4413 [7]. The experiment emphasizes on the flexibility behavior and internal energy by volume with 3 types of brake lining and pads. For the experiment focused on conditions by normal apply brake repeat apply brake and suddenly apply brake. The results revealed the normal apply brake condition the maximum and minimum of flexibility behavior was appeared on brake lining and pads type A and type C with testing temperature at 2000C. By the repeat and suddenly apply brake conditions the brake lining and pads type C and type A with 300C is given to the maximum and minimum flexibility behavior. In case of internal energy by volume the maximum and minimum energy was appeared on pads type C and B at the 300C of testing temperature. For the testing temperature at 200 and 4000C the pads type A and type B were got the maximum and minimum energy respectively. On the other hand at the high flexibility behavior is given to high internal energy at the high temperature of the apply brake condition.

การศึกษาโครงสร้างกันแรงกระแทกของรถยนต์ด้วยวัสดุทางเลือกที่ส่งผลต่อการดูดซับพลังงาน
การศึกษาโครงสร้างกันแรงกระแทกของรถยนต์ด้วยวัสดุทางเลือกที่ส่งผลต่อการดูดซับพลังงาน

Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.

Water Hyacinth Yarns and Their Transformed Materials Dyeing Machine for Developing Small and Medium-Sized Enterprises was a research project what an aim for producing a prototype dyeing machine. The machine was used at the small enterprise in Nakhon Prathom province. The dyeing machine was contributed by stainless steel. The outer dimension was 100 centimeters in height 130 centimeters in length and 90 centi-meters in width. The inner structure contains with perforate stainless steel drum. It had diameter as 80 centimeters with 90 centimeters length. The container capacity was 27 liters for the raw material as 10 kg of the dry Water Hyacinth Yarns or 5 kg of the dry Water Hyacinth roots. The machine was running test for reactive dyeing process at 80oC for 30 minutes. The machine was achieved for reduce time operation as 5 times and gas consumption as 2.38 times. The break-even point was 1.09 year and B/C as 2.22. Moreover it can solve the fuzzy yarns problem and the volatile smoke during the tradition dyeing. The knowledge was transferred to the stakeholders at the target area as “Chumchonjaksanpaktobchawha Bann klongnokkratum” enterprise in Nakhon Pra thom province. They were satisfied in this benefit in good to very good level.
