This research aims to develop the ceiling board mixed with coconut coir. The 5 ratios of gypsum plaster: coconut coir: sodium silicate: tap water are equal to 1 : 0 : 1: 0.03 1: 100: 1: 0.03 1: 150: 1: 0.03 1: 200: 1: 0.03 1: 250: 1: 0.03 และ 1: 300: 1: 0.03 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of ceiling board mixed with coconut coir followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density and thermal conductivity coefficient. From the results 1 : 1 5 0 : 1: 0.03 is the most suitable ratio of ceiling board mixed with coconut coir. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products

The purpose of this research was to study the satisfactions of the trainees towards the services of Good Government official course of Ministry of Natural Resources and Environment. The research aims to 1) study the satisfaction of trainees for service of fiscal year 2015 2) compare to the basic factors of trainees for service. The 350 questionnaires were distributed to the trainees. It found that 346 questionnaires (98.85%) were returned. To analyze the data mean standard deviation t-test and one-way ANOVA were employed. The results of the study showed that satisfaction of trainees in training service in 5 aspects at the high level. In term of genders and sectors found that are male and female had different satisfaction in the confidence level of 0.05 But in term of lecturer and teaching technique there are no satisfactions satisfaction difference between male and female. And there are no difference in each sector at the 0.05 level but the training and the lecturer and teaching had different satisfaction.

This research aims to study the water hyacinth fiber inside high density cement fiber board. By using ratio components among cement : fine sand : water hyacinth fiber : water : catalyst accelerated the formations of cement (aluminum sulfate (AI2 (SO4) 3) calcium chloride (CaCl2) sodium silicate (Na2SiO3)) on the ratio 1: 0.2: 0.075: 0.3: 0.03 by weight of total water hyacinth fiber. The 5 ratios consist of 0.0 (A1 D1 formulae) 0.025 (A2 B2 C2 D2 formulae) 0.050 0.03 (A4 B4 C4 D4 formulae) and 0.1 (A5 B5 C5 D5 formulae) by weighted all fibers were treated with sodium hydroxide solution (NaOH) at a concentration of 12%. The fiber to solution ratio was 1: 10 boiled in open system at 100 °C for 1 - 3 hours. By compressing the mixture cast machine at normal temperature (30 - 35 °C). Use a density of 0.75 g / cm3. From the test results the ratio B4 is the appropriate ratio. Can pass TIS 878- 2537 Cement Board: high density and physical properties mechanical properties and thermal insulation are good. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2)

The objective of this study is to examine Banking Sector’s anomaly in the Stock Exchange of Thailand (SET): The influence of Market Capitalization and P/E ratio. The study focuses on 11 stocks in banking sector from January 2012-December 2016 to tally 26840 samples. The factors of this study are the return of these stocks the return of SET the market capitalization and P/E ratio of banking sector in the Stock Exchange of Thailand. The study classifies these stocks into 4 groups as following - Low market capitalization group - High market capitalization group - Low P/E ratio group - High P/E ratio group The multiple linear regressions with Ordinary Least Squares (OLS) are used in analysis at the statistically significant level of 0.1. The result shows that all 4 groups do not have statistical relationship with the return of banking sector in SET. The conclusion of this study is that there is no anomaly of banking sector from the influences of market capitalization and P/E ratio.

This research aims to study the development of the Para rubber press machine with wrought pattern for continued 2-year project. Used natural Para rubber mixed in ta-Kuong by normally practical Para rubber farmers to evaluate the rubber press machine. It has developed the 11 roller the 3 plain duo sets of normal press rollers and the 2 duo sets of wrought rubber press rollers with the induction motor at 1430 rpm. The rotating transmission based on belts and chains. The evaluated results produced the dried Para rubber sheets thickness at 3.75 mm. on average as standard market need. From a robber sheet with enough patted on with a worker to carry the ta-Kuong to a top tray and a rubber press man to put the Para rubber piece to a machine on average the completed 185 wrought rubber sheets per hour in shorter time.
