การปรับปรุงความเหนียวของพอลิแลกติกแอซิดด้วยวัสดุธรรมชาติที่ผ่านการดัดแปร

This research work was to study the toughening modification of polylactic acid by the mixing with epoxidized natural rubber (ENR) and the increase of effectiveness of mechanical properties with a compatibilizer. Enhancement of properties in polylactic acid was evaluated by tensile and impact testings Fourier-transform Infrared Spectroscopy (FTIR) technique Differential Scanning Calorimetry (DSC) technique and Scanning Electron Microscope (SEM). For the addition of ENR it was revealed that the increase of ENR contents improved elongation at break and impact strength but decreased tensile modulus and ultimate tensile strength. Glass transition temperature (Tg) percentage crystallinity and the melting point of polylactic acid tended to decrease with the addition of ENR. Chemical change was found that position of C=O peak in polymer blend was slightly shifted as compared to the spectrum of neat polylactic acid. The optimum formulation for toughening modification was ENR content of 30 wt%. Its impact strength was 1982.55 % of neat polylactic acid. For increasing effectiveness of mechanical properties with a compatibilizer it revealed that the addition of Joncryl ® ADR-4300 as compatibilizer improved both tensile and impact properties. The optimum loading of a compatibilizer for improving mechanical properties was 0.5 wt% of polylactic acid. The decreases of crystallinity and melting point of polylactic acid with adding Joncryl ® ADR-4300 might be because Joncryl ® ADR-4300 was also chain extender of polylactic acid and it might be obstructing crystallization. The presence of Joncryl ® ADR-4300 unaffected on Tg value and chemical change.

The research on opinions and demands of viewers digital TV via applications has objectives as follows 1. to study the opinions and needs of users who view digital TV via application; 2. to study the opinions and needs of the management from agencies organizations public sector private sector state enterprises and scholars involving in television media industry; 3. to establish guidelines for developing appropriate program format for digital TV application. The researcher used mixed research methodologies by combining two methodologies qualitative research and quantitative together. Both methodologies were used in conducting this research simultaneously in a single period. Data of both methodologies was collected and analyzed separately whereas the results were combined and interpreted. Then the results were discussed by comparing the similarity and difference of both methodologies. The qualitative research methods consisted of document review observation and in-depth interview. The quantitative research methods consisted of questionnaire from sample groups and statistical analysis. Research results revealed that according to opinions and demands of viewers digital TV via applications (most people downloaded digital TV viewing application on Android platform) the most watched channel is channel 8; on average they watched digital TV 5 days per week with minimum 3 hours of viewing time; the types of program that people watch regularly were dramas which they can watch offline afterwards. Overall the users had positive attitude towards their experience in using digital TV application with average score totalling 3.96. The factor that received the highest score was the convenience of using digital TV application which received average scores totalling 3.96 (agree). The second highest score which totalled 3.85 (agree) was usefulness. Usage protocol received 3.79 scores (agree) and service received 3.56 scores (agree). The most important factor according to the sample groups when choosing digital TV application was quality. Features format and structure were then considered respectively. As for the opinions of the management from agencies organizations public sector private sector state enterprises and scholars involving in television media industry they wished to see constant development in digital TV programs that would keep up with the ever changing technology as well as marketing factors relating to advertising incomes and other incomes.

The purposes of the study “The Design of Lady Casual wear in Minimal Style from Resak died cotton cloth” were 1) to study design of Lady Casual wear in Minimal Style from Resak died cotton cloth. 2) to study consumer satisfaction with Lady Casual wear in Minimal Style from Resak died cotton cloth. Minimal Art Concept was used to guideline The Design of Lady Casual wear. The Design of Lady Casual wear was composed of 18 clothing sets 6 types. The five Fashion Design Specialist by Purposive Sampling chose one from six sets. The researcher sewed 6 clothing sets which were selected and after that the 6 sets were used to find out the satisfaction of female students at Home Economics Rajamangala University of Technology Phra Nakhon. A sample was selected from accidental sampling. Data was analyzed by Percentage Compensation and Standard Deviation. The results finding of the consumer satisfaction with Lady Casual wear in Minimal Style from Resak died cotton cloth showed that target groups are satisfied at a high level. The first is the shirt and skirt type (average 4.42).The second is the Overalls type (average 4.36). The third is the Blouses and shorts type (average 4.35). The fourth is the Blouses and trousers type (average 4.21). The fifth is the Coat type (average 4.10) and The Last is The Dress type (average 3.99).

The objectives of the Development of Thai Song Dum Fabric Pattern by Computerized Embroidery Machine for Living Room Products are as follows 1) to develop Thai Song Dum fabric pattern with computer machine for living room products and 2) to study the satisfaction of consumers towards the pattern of Thai Song Dum fabric with computerized machines for living room products. The sample group consumers who visit Bang Luang Market Thung Bua Daeng Floating Market and Lam Phaya Floating Market by using 50 consumers in each market including 150 consumers in 3 markets used to analyze data such as mean percentage standard deviation and analyzed the data by using computer software. The results of the research showed that most consumers were satisfied with the overall picture at a high level. The satisfaction of consumers Bang Luang market the first is the living room product the Dok Priew pattern with an average of 4.47. The Dok Chan Lom pattern has an average of 4.40 and the Dok Bua pattern has an average of 4.37. The consumer satisfaction Thung Bua Daeng floating market. The first is the Dok Bua patterned living room product has an average value of 4.56. The Dok Chan Lom pattern is 4.50 and the Dok Priew pattern has an average of 4.44.
