3D Motion graphic ล่องเรือเจ้าพระยา

The objectives this special project were to produce the Chao Phraya Cruise 3D Motion Graphic media and to study about the satisfaction of the audiences who watched Chao Phraya Cruise 3D Motion Graphic which the target was 100 of foreign tourists and Thai Tourists. Under this study the statistics used for analyzing the data were frequency percentage average and standard deviation. The study indicated that the samples were satisfied with the Chao Phraya Cruise 3D Motion Graphic about content was at a high level (= 4.41 S.D.= 0.66) and about quality was at the highest level (= 4.63 S.D.= 0.58)

Effects of chitosan contents on latex properties and physical properties of natural rubber latex/chitosan composites
Effects of chitosan contents on latex properties and physical properties of natural rubber latex/chitosan composites

In this study natural rubber latex/chitosan (NRL/CT) composites were prepared by latex mixing. The effects of chitosan on latex properties and physical Properties of NRL/CT composite films were focused. It was found that there was no significant change in the latex properties with increasing CT content. Increasing CT contents of 0.5 to 8.0 phr caused the rising of 300 % modulus of the NRL/CT composite whereas the opposite trend was found for tensile strength and elongation at break. The antimicrobial efficacy of the chitosan-incorporated rubber was slightly enhanced from that of the non-chitosan rubber. By comprehensive consideration CT content suitable for antibacterial gloves according to Thai industrial standards (TIS 1056-1: 2013) was 1 phr. For other latex products that require high modulus and antibacterial activity such as tubing pillow foam rubber nipple and catheter CT could be used at higher contents from 2 to 4 phr.

This research aims to study the achievement evaluation of CPD program for accountants as required the Department of Business Development. The data were collected from a sample of 200 accountants in Bangkok area who registered with the Federation of Accounting Professions using questionnaire and individual interview. The statistics used for data analysis were Percentage Mean and Standard Deviation. The research found that the respondents were mostly female half of them were 31-40 years old and over 20 years of working experiences and completed a bachelors degree in accounting mostly married status and average salary was 20001-30000 baht per month thus higher than the minimum standard (15000 baht per month). The respondents was rated to be most appropriate as a whole including Lecturer Training Method and Training Curriculum (4.28 points average). In addition the achievement was at a high level (3.84 points average). The curriculum was utilized at the moderate level (3.33 points average). Finally the knowledge utilization was utilized namely in practice 79.50 percent the knowledge transfer to the colleagues 11 percent and the others 5.00 percent and unutilized 4.50 percent.

This research aims to investigate and test the feasibility of the production of natural teak sheets and study the appropriate production methods. Study physical properties and mechanical properties to compare with industry standard insulation sheet. The ratio of tattoo and hyacinth. 5% 7% 9% of the material were dried at 400 600 800 kg / m3. The results showed that the modulus rupture. Elastic modulus And thickness swelling. It varies with the amount of glue. The nature of the tattoo causes absorption in the material if the density increases the water absorption will decrease. Compared to standard insulation products. The amount of adhesive is 7% of the weight of the material when dry. The density of 800 kg / m 2 is 25 kg / cm2. 140 degree Celsius ruptured modulus and elastic modulus But the thickness of the swelling has not met the criteria. In the next production should be mixed waterproofing in the work.

This research work was to study the improvement of toughness of polylactic acid (PLA) and the cost reduction of raw material with addition of untreated and treated oil palm fiber (OPF). The detail of this work was divided into two parts. The first was to find the suitable condition for surface treatment of OPF with sodium hydroxide (NaOH). The second part was to study the effect of untreated and treated OPF contents on the mechanical properties of PLA. For surface treatment of OPF NaOH concentrations and immersion times were varied from 0 to 15 wt% and 0 to 30 min respectively. Aspect ratio (L/D) and surface of untreated and treated OPF were investigated by using optical microscope and scanning electron microscope (SEM) respectively. The result suggested that the most suitable condition for surface treatment of OPF was NaOH concentration of 10 wt% at immersion time of 20 min. Treated OPF was occurred microporous and had more rough as compare to untreated fiber. For the effect of untreated and treated OPF contents on the mechanical properties of PLA it was evaluated by tensile and impact testing. SEM was used for investigation of interfacial adhesion and fiber dispersion. The results showed that tensile modulus and impact strength tend to increase with adding 2.5 wt% OPF content and slightly changed at higher OPF content whereas ultimate tensile strength and elongation at break decreased with increasing fiber content. Surface treatment with NaOH led to enhancement of mechanical properties of composite due to improve interfacial adhesion and fiber dispersion.
