The objectives of this research are to construct and determine the quality and efficiency of a simple vibration experiment package. This experiment package design was based on free body diagram of content and main knowledge analyzed from behavioral objectives. Quality of the experiment package was assessed by 12 experts in 4 aspects which included theoretical sheet experimental sheet exercise sheet and experiment device design. The efficiency evaluation was performed by a sample group of 18 students. The exercise sheet was done by the students after finishing each teaching topic and examination sheet was done after finishing all teaching topics. Results showed that quality of the constructed simple vibration experiment package was in a high level of 4.8. Efficiency of the experiment package was 80.47/81.85 which was higher than specified in the research hypotheses. Therefore the experiment package could be applied to teach in any classroom with high students learning outcome.

A study on developing textile products from fiber lemongrass has been carried out aimed at processing yarn from lemongrass fiber developing textile fabrics such as clothing hats and shoes and teaching product design and technology to a community. Lemongrass leaves were processed with chemicals to produce a fiber lemongrass then spun to 100% lemongrass yarn with large unsmooth surfaces the used to produce handbag hats and shoes. However for garment fabrics the researchers developed the lemongrass yarn for weaving by mixing cotton in a 60:40 ratio to produce hand-woven cloth. Using hand-woven folk wisdom the Takfa community in Nakhon Sawan produced natural dyes from Bengal Almond leaves a performed surface finishing for a smoother touch. After weaving lemongrass fiber cloth gives off a lemongrass odor but this fades gradually. The physical properties of lemongrass fiber cloth are then tested for strength resistance and abrasion. Processing lemongrass cloth fiber to textile products enables us to produce various products such as clothes bags and hats. In passing technology to the community the residents recognized the advantages and benefits of using the fabric. Further research should investigate mixing lemongrass fibers with other natural fibers improved fiber durability luster of the fiber to increase fiber value or using lemongrass fiber for household products.

This research had an objective to research and development the garments and accessory products from Karen Woven Fabric. There were 3 product types as dress:D shirt:S and accessory:A what they were 15 styles/type. This research was survey research that used the Index of item-Objective congruence questionnaires (IOC) as the major tool. Addition the computer graphic aided was used to design the products under the design principle. The results showed the good level consumer responsibility. The consumer favored of the products followed: for dress was D8 > D7 > D3 > D5 > D1 > D4 > D2 > D10 > D11 > D6 > D14 > D10 > D13 > D12 > D15 for shirt was S8 > S7 > S3 > S5 > S1 > S11 > S10 > S9 > S1 > S4 > S6 > S14 > S13 > S15 > S12 and accessory was A5 > A2 > A4 > A1 > A3 > A11 > A6 > A7 > A10 > A14 > A15 > A8> A9 > A13 > A12. Moreover the whole satisfactions level of the consumer for all products in term of the useful modern style Karen conservation style and color theme were good. All of results were transfer to the target group at Bann YangNamkladtai school Phetchaburi province. The transfer group was satisfied and gain the worth knowledge. This cognition was a way for building the career and produces the commercial products in the future.

This research study design and home furnishing materials for residential medium-sized grass. Study materials are made of grass to create commercial benefits. And determine the appropriate form furnished house has many of the current medium. Products include standard tests to determine the standard of grass in the structure of furniture design. The model home furnishing materials vetiver from interviews with experts in the design. Conclusions regarding the manufacture and design of a study to determine specialists as appropriate. Researchers have taken a home furnishing is correct. Then residents of the residential-sized survey about home furnishing 30 who works as follows. Front of the house. The average was 4.6 most of the comforts average was 4.6 most security average is 4.75 most of the design value is 4.7 the overall satisfaction is at its greatest. The test standard furniture.
