การผลิตและพัฒนาบรรจุภัณฑ์ที่ย่อยสลายได้จากวัสดุเชิงประกอบพลาสติก ชีวภาพและเส้นใยธรรมชาติที่ผ่านการปรับปรุงด้วยสารไซเลน
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.
ถุงดูดซับธรรมชาติจากกากกาแฟหมักด้วยน้ำคีเฟอร์เพื่อดูดซับคราบน้ำมันปนเปื้อน
Oil spills in every household caused by cooking are difficult to eliminate when accumulating for a long time. In this study the researchers aimed to develop the remaining coffee grounds for oil absorption. From 2 coffee ground samples types A and B obtained from different coffee shop & coffee grounds type A demonstrated more effective in absorbing vegetable oil. The sample A was thus treated with hydrogen peroxide (H2O2) solution at the concentration of 0.5 1 3 33 50 80 and 100 percentages for 30 minutes and determined for the efficiency in oil elimination. The sample with at least 80 % (v/v) H2O2 showed the most effectiveness in absorbing oil. The coffee grounds that were later treated with pineapple juice fermented Kefir could help increase coffee ground degradation at 51.07 percentages. The Kefir treated coffee grounds packed in an absorbent bag revealed higher effectiveness in oil absorption at least 51.07 percentages compared to the controls that were cotton bag and coffee a harboring at the percentages of 73.85 and 30.04 respectively. This coffee ground bag after thrown into the ground could be decomposed in nature for 52 percentages within 1 month. Due to the oil elimination properties of the coffee grounds that are environmentally and human friendly as well as low cost it is possible to develop the kefir treated coffee grounds for being oil-absorbing products that can come in contact with human skin.
การสื่อสารการตลาดที่มีผลต่อการตัดสินใจซื้อผลิตภัณฑ์บำรุงผิวญี่ปุ่นของผู้บริโภคเพศหญิงในกรุงเทพมหานคร
The purposes of this study were to compare demographics to making purchasing decisions to Japanese skincare products of female consumers in Bangkok and study the marketing communications affected the buying decision Japanese skincare products of female consumers in Bangkok. This research was the quantitative research by using questionnaires from 384 female consumers who previously purchased the product by uses the multi-stage sampling method. The data was analyzed by as frequency percentage mean standard deviation t-test statistic One-Way ANOVA and enter multiple linear regression at the statistical significance level of .05. The results showed that: most of the sample was between 25 - 34 years (35.40%) single status (68.20%) average monthly income of 10001 - 20000 baht (34.10%) education of bachelors degree (55.70%) and work in private companies (48.70%). The average monthly income education level and occupation had different decisions purchasing Japanese skincare products among female consumers with statistical significance at the .05 level. Marketing communication influence female consumers purchasing decision of Japanese skincare products with statistical significance at the .05 level were sales by individuals (29.10%) public relations (18.10%) and promotion (15.80%).

This research was a quantitative research. The purposes of this research were 1) to study demographic characteristic affect on purchasing intentio n of beauty products in Multi-Brand Store 2) to examine online marketing communication affects on purchasing intention of beauty products in Multi-Brand Store and 3) to examine Brand Equity affects on purchasing intention of beauty products in Multi-Brand Store. The data were collected 400 samples who were customers to purchase products through in Multi-Brand Store. The statistical methods used to analyze data were frequency percentage mean standard deviation one-way analisis of variance and enter multiple regression analysis with a statistical significance level of .05. The results showed that: most of the respondents were female (69.50%) the age between 27-32 years (58. 30 %) education of bachelor’s degree (77. 5 0%) business of employee (56.80%) and average monthly income between 15001 – 30000 baht (61. 00 %). Diffenct Demographic characteristics included gender age career and average monthly income had purchasing decision intention of beauty products in Multi-Brand Store with statistically significant at the .05 level. Marketing mix affects on purchasing decision intention of beauty products in Multi-Brand Store with statistically significant at the .05 level with the two affects including product increased (17.80%) price increased by 22.10 percent. Brand equity affects on purchasing decision intention of beauty products in Multi-Brand Store with statistically significant at the .05 level with the two affects including brand awareness increased by 3 0 . 3 0 percent and brand associations increased by 33.30 percent
