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.
การพัฒนานวัตกรรมทางการบัญชีของธุรกิจขนาดกลางและขนาดย่อม (SMEs)
This research aimed to study organizational characteristics and organizational supporters that affect the innovative development of small and medium enterprises (SMEs). The independent variables were organizational characteristics based on McKinsey’s 7S framework (strategy structure systems style staff skills and shared values) and organizational supporters (technology and government support). The dependent variables were guidelines for accounting innovation development. Sizes of the organization were control variables. The sample group in the study consisted of 309 small and medium enterprise entrepreneurs. Data were analyzed using descriptive statistics and inferential statistics (multiple linear regression). The results showed that strategy systems staff technology and governmental support affect the innovative development of small and medium enterprises (SMEs) at the .05 level of significance. According to small and medium enterprise entrepreneurs management accounting innovation and financial innovation were very important to SMEs (X ±S.D. equal 3 . 6 1 ± 0 . 8 2 ) . To develop SMEs’ accounting innovation entrepreneurs need to determine clear strategies policies and goals for innovation manage data systems to be exchanged in organizations and set a motivation system for innovation development. Staff development plans should be created for knowing and understanding innovation. Apart from organization management SMEs need to get government support and adapt technologies to accounting to increase the efficiency of accounting information.
การพัฒนาสื่อการเรียนการสอนวิชาประวัติศาสตร์ ชั้นประถมศึกษาปีที่ 4
The purposes of this research were to develop learning and teaching media on history primary 4 and study the satisfaction of the viewers who watched the media Development of media infographics in the form of fire parallax And can be used for the most benefit Population groups used in this project study are People who watch the media develop media infographics in the form of parallax on fire. Were selected by random selection of 30 people. The study found that the Development e-learning for history primary 4. The media satisfaction is at a high level.
การพัฒนาสื่อเสริมการเรียนรู้แบบโต้ตอบในวิชาภาษาจีน
This study aims to develop interactive learning interactive Chinese modern andeasier to understand. To increase student achievement before and after learning. And satisfaction of learners with interactive learning interactive learning in Chinese. The samples to compare student achievement before and after learning and satisfaction of students in the ninth grade at one school Photisarn Pittayakorn. Phuttamonthon 1 Bang Bang Ramat Bangkok 2 classrooms of 36 people divided into two groups: a control group and an experimental group of 18 people 18 of them using a questionnaire to collect data. The statistics used for data analysis were frequency percentage mean standard deviation. And t test (t-Test) results showed that: 1) the development of interactive learning interactive Chinese modern and more easily understood 2) achievement after learning with the learning materials. interactive Chinese learning higher than before and 3) the students are satisfied with the media in an interactive learning Chinese at a high level.
