An ability of fresh banana peel without surface modification was evaluated for the removal of lead ions from aqueous solution. Batch adsorption was performed at room temperature. The experimental conditions including dosage contact time initial concentration of lead( II) ion were studied. The characterization of fresh banana peel was carried out by Fourier-transform infrared spectroscopy (FTIR) and energy dispersive X-ray fluorescence ( ED-XRF) . The isotherm models of Langmuir and Freundlich were used to describe the adsorption mechanism involving the relationship between adsorbent surface capacity and adsorbed degree of lead(II)ion in the equilibrium conditions. The experimental data fitted well to the Langmuir isotherm with a correlation coefficient of r2 greater than 0.86. The Maximum adsorption capacity (qm) was found to be 0.9151 mg/g. The results of ED-XRF of fresh banana peels before and after treatment with lead( II) ion confirmed that lead( II) ion was occupied onto the surface of fresh banana peel. Moreover the inside of fresh banana peels was found the lead(II)ion larger than the outside peels. It was concluded that waste of banana could be used as a low-cost adsorbent for removal of lead(II)ion from aqueous solution based on a simple adsorption method.

Costume fashion design thesis that reflect the character of LGBTQ from Lady Gagas inspiration aims to study the type of concept type of structure decoration technique of costume and emotional scene in the music video Born This Way by Lady Gaga in order to create the concept of costume that show the LGBTQ identity. The tools that use for study is two type of analysis which is Lady Gaga costume analysis. this part used three standard to analyze 1)concept 2)structure 3)decoration Second one is Lady Gagas costume design analysis by separated in to three part of analysis. 1)concept 2)structure 3)emotional scene aims to study the physical character and over all analysis in order to create constructively costume concept which is reflect the LGBTQ identity The results of the study showed that Lady Gagas costumes and interpretations have a distinctive feature of the distinctive layout decorative techniques and emotional scenes in the Born This Way music video emphasizing the importance and reflection of reflection. The identity of the third gender in order to be accepted by society by using the information obtained as a guideline in costume design that reflects the identity of the third gender and focuses on creating their identity and promoting the new generation in society to recognize and accept

The objectives of this research were to study the cost structure of rice cultivation with the activity-based costing method and to compare the cost structure of rice cultivation with the activity-based costing method in Chaiyaphum Province. The sample of this research was 50 rice farmers in Ban Khwao District and 50 rice farmers in Khon Sawan District. A questionnaire was used to collect data. Data were analyzed using descriptive statistics including percentage average standard deviation and t-test dependent samples. The results of this study showed that the cost structure of rice cultivation using the activity-based costing system method in Chaiyaphum province consisted of direct material cost direct labor cost and production cost. The direct material cost structure of Ban Khwao district was 232945 baht meanwhile the direct material cost structure of Khon Sawan district was 167850 baht. The direct labor cost of Ban Khwao district was 503600 baht meanwhile direct labor cost of Khon Sawan district was 473250 baht. The production cost of Ban Khwao district was 122610 baht meanwhile the production cost of Khon Sawan district was 121320 baht. The comparison of cost structure of rice cultivation with the activity-based costing method of Chaiyaphum Province showed that total cost of Ban Khwao district was 861605 baht meanwhile total cost of Khon Sawan district was 764970 baht. This implied that total cost of Ban Khwao district was higher than that of Khon Sawan district.

The purpose of this research was to: 1) to study the Thai Khon dress. 2) to design and develop the printed pattern for the casual wear in a graphic style using the unique Thai costume. 3) to study consumer satisfaction of develop of the printed patterns for casual wear in graphic by using the identity of the costume Khon Thai. The instruments used in this study were 27 patterns 27 styles 9 pattern prototype products and a satisfaction questionnaire. The samples were students and staff aged between 20-40 years at Rajamangala University of Technology Phra Nakhon (Chotiwat Center) used 345 purposive sampling methods. The method of determining the size of the sample by Taro Yamane method was at a level of confidence of 95% and the assumption was that the individual factors were different the level of satisfaction with the printed pattern for the casual wear in the graphic format different to inquire and analyze different personal factors. The research found that the samples were 20-25 year old female single status bachelor’s degree students with less than 15000 baht. There were reasons to choose a printed outfit for casual wear or printed outfit: from personal favorite aesthetics modern style with the frequency of purchase every 3 months. The agenda of wearing was a common opportunity price less than 500 baht per person and with the decision to buy by oneself. The design of printed motifs inspired by Thai Khon costumes with the highest level of satisfaction was the monkey print. The satisfaction with the printed pattern of casual shirt (TOP): the highest level of satisfaction was the monkey printed motif the second was the giant and then the leading actor and actress respectively. The satisfaction with the printed pattern of casual shirt (BOTTOM): the highest level of satisfaction was the monkey printed motif the second was the giant and then the leading actor and actress respectively. The satisfaction with the printed pattern of casual wear (DRESS): the highest level of satisfaction was the monkey the second was then the leading actor and actress and the giant respectively. The differences in personal factors on the satisfaction of printed patterns for casual wear in graphic form were by gender age occupation average income and different education as well as the satisfaction to printed patterns for casual wear with different graphical styles.

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
