This research aims to study the application of coconut meal and corncob fiber as high density cement-bonded fiberboard. The cement: fine sand: coconut meal and corncob fiber: water: cement setting accelerator (aluminium sulphate (Al2(SO4)3) calcium chloride (CaCl2) sodium silicate (Na2SiO3)) ratio is equal to 1: 0.2: 0.05: 0.3: 0.03 by weight. The fibers are taken from coconut meal: corncob that 5 ratios are used following: 0.0500: 0 (CN0) 0.0375: 0.0125 (CN25) 0.0250: 0.0250 (CN50) 0.0125: 0.0375 (CN75) and 0: 0.0500 (CN100) by weight. 12% of Sodium Hydroxide (NaOH) was used to modify the fibers by using 1: 10 of fiber: solution and boiling 100 degree of Celsius (1-3 hours). The fiberboard production use pressure casting in normal temperature (30 – 35 degree of Celsius) and 0.75 g/cm3 of density. Resulting the CN75 ratio is suitable ratio which pass TIS 878-2537 standard (cement bonded particle board: high density) and has good physical properties mechanical properties and thermal insulation. The most suitable cement setting accelerator is calcium chloride (CaCl2).

This research aims to evaluate the effectiveness and limitations of the Road Safety Audit in Thailand. The evaluations would be used as a guideline to set Road Safety Audit policy for transport authorities in order to enhance the traffic safety in the construction area. In the study the construction project route 318 Trat-Had Lek part2 (Section1) Sta.1+900.00 to 20+000.00 (total distance of 18.100 kilometer) was selected as a case study. The accident statistics occurred before the construction and during the construction were compared to analyze the effectiveness of the Road Safety Audit used in the project. The result of the study shows that the main cause of the accident are traffic management traffic sign and marking as well as pavement surface. Therefore the researchers have provided some recommendations against the accident causes. Finally the operations of the contractors according to the recommendations were monthly summarized to measure the effectiveness of the recommendations.

The image enhancement process of a digital image is a part of digital signal processing which it plays an important role in some industrial segments for instance object classification or bio-identification satellite exploration or aerial images robot vision cancer treatment etc. These image applications are necessary to consume many resources in physical hardware and computer programming including the intelligent algorithm development of complexly advanced processing in order to enhance digital images – as well as be easy to analyse by humans. This research is aimed to present on Contrast Enhancement using Bi-Histogram Equalization via Two Dimensional Discrete Wavelet Transform (BHE2DWT) in order to compose the coefficient wavelet from other signals. At the end of the process information on the approximation band from DWT will be divided into two sub-histograms and then histograms will be independently equalized. After that resulting histograms will be decomposed by IDWT. Resulting images will be not only more displaying in high contrast than their original images but also preserve the absolute mean brightness error (AMBE) to close their original images.

The purposes of this research were to investigate the desired characteristics of the Applied Thai Program’s graduates of the faculty of Liberal Arts and to compare the graduate users’ personal factors. The subjects were business organizations and executive managers. The research tools were questionnaire and interview. The data were analyzed by percentage mean standard deviation and F-test. The findings were as follows: As for employers’ satisfaction towards the graduates’ qualifications the desirable characteristics of the graduates both overall and within each aspect are at the high level ( x= 3.84). Moral and ethical behavior rated the highest desirable characteristics (x= 4.01) followed by domain of psychomotor skills (x= 3.99) as well as interpersonal skills and responsibility (x= 3.84). As for the comparison of the graduate users’ personal factors it was found that: as for types of business organizations the overall mean value of types of business organizations was not different but the mean scores of moral and ethical behavior and domain of psychomotor skills were statistically significant at 0.01 level. As for positions of graduate users the overall mean value of positions of graduate users was statistically significant at 0.01level. Moreover the mean scores of knowledge and university identity were statistically significant at the level 0.01 while the mean scores of moral and ethical behavior mathematical analysis skills communication skills information technology application skills and domain of psychomotor skills were statistically significant at 0.05 level. As for working experiences the overall mean value of working experiences was not different but the mean scores of university identity was statistically significant at the level 0.05. As for working tenure the overall mean value of working tenure was statistically significant at 0.01level. Moreover the mean scores of moral and ethical behavior knowledge cognitive skills interpersonal skills and responsibility mathematical analysis skills communication skills information technology application skills and domain of psychomotor skills were statistically significant at 0.01level while the mean scores of university identity was statistically significant at the level 0.05. As for employers’ needs the first desired characteristics of the graduates were information technology application skills and basic computer knowledge. Thai and English oral communication skills were the second desired characteristics.

This research aims to establish and measure the quality of students language proficiency Thailand for foreigners. Practical application Thailand Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon The sample of Chinese students High levels of Nanning 3rd year of study in Thailand. Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon No. 13 Semester 1 Academic year 2557 results were found. Measurement of Proficiency in Thailand. For Chinese Students The 3rd year of study in Thailand. Faculty of Liberal Arts The researchers created a multiple choice answer four options with 50 items measuring five aspects: the opposite of 10 questions the meaning close to 10 on the wrong side of 10 the right to have 10 problems and aspects. Selection of 10 items is measured with a content validity index based on the consistency of 1.00 with the difficulty (p) from 0.43 to 0.89 with discrimination (r) from 0.13 to 0.60 validity. Correlation coefficients ranging from 0.11 to 0.55 and the reliability coefficient for Bucks alpha ranging from 0.80 – 0.82 split half reliability ranged in value was 0.88 The results of the research can be a tool to measure language proficiency level of Thailand. Thailand is the language of international students at a certain level.
