This work aimed to study the improvement of mechanical properties and cost reduction of biodegradable packaging made from polylactic acid (PLA) by using sisal fiber. Because sisal fiber as natural fiber is good mechanical properties biodegradable material and low cost. The variables studied were the addition of sisal fiber surface treatment with epoxy silane and fiber direction. Their effects were investigated by tensile flexural and impact testings and morphology analysis. The results suggested that the addition of sisal fiber increased Young’s modulus Flexural modulus and ultimate tensile stress whereas elongation at break and impact strength tended to decrease. For the effect of surface treatment it was found that tensile and flexural moduli increased with epoxy silane treatment but tensile flexural and impact strengths slightly changed. Surface treatment by epoxy silane led to good interfacial bonding by hydrogen bonding between oxirane ring of epoxy silane and hydroxyl group of PLA. The effect of fiber direction revealed that tensile properties of composite in fiber direction of 0o were higher than those of composite in fiber direction of 45o. Fiber direction did not affect flexural and impact properties.

This research is conducted 1) to study the scenario model of the aesthetic plastic surgery business for preparing a Thai popular culture wave on medical tourism 2) to design the scenario model of the aesthetic plastic surgery business for preparing a Thai popular culture wave on medical tourism.The samples are the experts from both public and private sector 17 experts who has experiences in relation to the aesthetic plastic surgery. The samples are collected by purposive sampling.This study uses EDFR technique (Ethnographic Futures Research) for the future research. The tool for collecting data is questionnaire by distributing them 3 times. The data are analyzed by using descriptive statistics which included percentage mode and median.It considers the validity by confirming interquartile range absolute value between mode and median statistically. Furthermore it calculates the index of congruence (IOC) for checking the scenario model of the aesthetic plastic surgery business for preparing a Thai popular culture wave on medical tourism. The finding shows 1. According to the opinion of the expert the scenario model of the aesthetic plastic surgery business for preparing a Thai popular culture wave on medical tourism represents positive negative and potential future. However it includes 3 factors which are strategic factor quality and service factor successful factor by considering from the index of congruence (IOC) which has the frequencies more than 85% 2. The analyzing data which are from the return questionnaires regarding consensus panelists indicate that consistency rules of descriptive statistics which is in the range of 3.50-5.00 (the data which tends to be in the high or highest level) and interquartile range is less than 1.50. Also the differences between mode and median are not more than 1. Moreover the best practice is so called “TPOP model or Thailand pop model”. TPOP is created for image building and leads to country brand image building. It represents Thainess to the aesthetic plastic surgery business. TPOP model is checked by index of congruence (IOC) from five IOC experts. It reveals that IOC>0.50 are comprised of 1) Strategic factors 2) quality and service factor 3) successful factor. In sum the contents are valid to implement and develop in the future.

This research aims to develop the natural rubber and ethylene vinyl acetate (EVA) plastic floor tile with flame resistance property. The 6 ratios of natural-rubber STR 20: zinc oxide: stearic acid: sulfur: mercaptobenzothiazole: diphenyl guanidine: EVA plastic: antimony trioxide were equal to 100: 5: 2: 3: 0.5: 0.2: 20: 0 100: 5: 2: 3: 0.5: 0.2: 20: 20 100: 5: 2: 3: 0.5: 0.2: 20: 40 100: 5: 2: 3: 0.5: 0.2: 20: 60 100: 5: 2: 3: 0.5: 0.2: 20: 80 and 100: 5: 2: 3: 0.5: 0.2: 20: 100 by weight or phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension for 4: 29 to 5: 19 minutes. The properties of the natural-rubber floor tiles were tested under ASTM standard. From the results it was found that the natural rubber and ethylene vinyl acetate plastic floor tile with flame resistance property was the suitable ratio for using as the rubber floor tiles in building and extinguished a fire by themselves. The antimony trioxide effected to increase the density hardness and thermal conductivity and decrease the tensile strength tear strength and wear resistance properties of the natural rubber and EVA plastic floor tiles

One of important equipment in reforestation or tree planting is a pot for mulching tree saplings. Originally pots were made of clay but they were too strong. When the trees grow up the pots must be smashed in order to let the roots and the stems grow up. Plastic pots are a popular alternative to be potted tree saplings due to their longer usability flexibility keeping and easy cleaning. In addition they are light and easy to move or transport. Typical pots usually have holes at the bottom which make poor ventilation that caused the slow tree saplings growth. Pots with holes in the side let the air comfortably flow and the roots do not go to the bottom of the pot. When the pots are moved the tree sapling roots are not ragged this help reducing the mortality rate of tree saplings. To Construct and find out the efficiency of plastic pot injection molded with 7.7 cm. in size 8 cm. high 0.10 cm. thick and the weight of 20 grams in the specification form the work-piece can be injected. For Construction and finding out the efficiency of holes for putting the plastic pot injection molded with 41 cm. wide 51 cm.long0.20 cm. thick and the weight of 330 grams in the specification form every work piece can be injected. There are 18holes for putting the plastic pot and all 18 holes are in the same size. Asst. Prof. Prasong KanKaew

This research was the basis for the design and development of home furnishings. Plastic woven from strands The woven plastic house hunters Si district seeking offense.The bulk sample from the production community in Angthong to represent the group of 50 people the researchers used a random sample quota (Quota Sampling) to obtain the desired characteristics of the sample. Then accidental sampling (Accidental Sampling) to the full amount required at the point of data collection and consumer groups. The research group defines a consumer as a representative group of 100 researchers by means of random sampling accident (Accidental Sampling) using questionnaires. The research found that The consumer and producer is of the opinion that the same approach in product form. The variance from the statistical products one is different with the two and there is a difference with the three products including the two have differences with the three significant at 0.05 number. three topics including the proper shape the suitability of woven pattern the suitability of the paint used on the products one has different products and the two products three. Significant at 0.05 Number 1 are beautiful and there is no difference between the three topics are appropriate for your size proportion appropriateness of materials used as components the adequacy of benefits. The analysis assessed consumer satisfaction with the products of home furnishings. Woven from plastic The woven plastic house hunters Si district seeking offense that overall consumer satisfaction with the product level. In the subsection are satisfied with the products good deal as well.
