The population was 1,210,043 savings cooperative members in Bangkok in 2019. The samples were randomly selected from the population by Purposive Sampling of 400 people. The sample size was determined according to Taro Yamane method. The data was analyzed using descriptive statistics such as frequency, percentage, mean and standard deviation. The inferential statistics were: independent sample T-test, one-way ANOVA analysis, Pearson's Correlation Coefficient and Multiple Regression Analysis. The study results showed that the overall service quality level of savings cooperatives in Bangkok was high. The aspects that the sample group thought was of the highest quality was the facilities and responses to member services. The most
important factors affecting the decision to use the services of the sample group were human resource development and service development. The study hypothesis test showed that personal factors namely age and membership duration in a savings cooperative affected the decision to use the service of savings cooperative member in Bangkok at a significant level of 0.05. The cooperative members aged 26-35 years focused on service development less than those aged 46 years and over at the statistical significance of 0.05.

Flexural performance of corroded reinforced concrete beams repaired with CFRP sheets
Get PDFRMUTP Research Journal, Vol. 15, No. 2, July-December 2021, pp 88-102Corrosion of steel reinforcements in concrete is one of the main causes of early deterioration and reduction of service loads of reinforced concrete (RC) structures. This paper reports the results of an experimental program that was carried out to evaluate the effect of reinforcement corrosion on the flexural performance of RC beams, and to investigate the efficiency of externally bonded carbon fiber reinforced polymer (CFRP) sheets to repair the corrosion-damaged RC beams. Seven RC beams with the same cross section and reinforcement details were prepared, including the control beam (B0). First, tension reinforcements of six RC beams were corroded by using an accelerated impress-current process to obtain corrosion levels of 15%, 30%, and 50% of weight loss, according to Faraday’s law. Then, three beams were repaired using CFRP sheets attached to the bottom surface, leaving the other three unrepaired. All beams were subjected to the four-point bending load test. The experimental results show that the corrosion specimens demonstrated a significant deterioration on the structural performance and the integrity by decreasing in their ultimate load capacity, stiffness, and ductility. The deterioration by corrosion of tension reinforcements can be successfully overcome using CFRP sheets as the repair material. The technique can restore the beam strength to its original design strength, except specimen B50F2 having severe steel-corrosion damage of 50%. A conservative value of the ultimate bending capacity of the beams with low corrosions (15%-30%) can be predicted by using RC conventional models, as suggested in ACI 318. However, the opposite trend is obtained for the high corrosion beam (50%). Appling ACI 440.2R provision to predict the ultimate flexural capacity of corroded beams repaired with CFRP sheets shows rather fair values for low corrosions (15%-30%), but significantly overestimates the strength of the high corrosion beam (50%).Rajamangala University of Technology Phra Nakho

EUV was converted to UV index, then the data was used for model development and forecasting of hourly UV index using Artificial Neural Network (ANN). The ANN model has one input layer, two hidden layers and one output layer. This input layer consists of extraterrestrial erythemal ultraviolet radiation, solar zenith angle, aerosol optical depth and cloud index which affect ultraviolet radiation, and the output layer is hourly UV index. The results show that hourly UV index obtained from ANN and that from the measurement are in reasonable agreement, with root mean square difference of 12.8% and mean bias difference of -2.4%. For forecasting of the hourly UV index, the data for 7 days earlier was used for forecasting the next UV index for one day or nine-hour (08:00 am.-16:00 pm.). Multi-layer perceptron and back propagation algorithm were used in the model forecasting. The results show that the UV index from the model forecasting is reasonable agrees with UV index from measurement with root mean square difference of 17.0% and mean bias difference of 0.3%.Rajamangala University of Technology Phra Nakho

maintain the moisture while reducing the water activity (aw) of the product. The objectives of this research were to study on humectants replacement and the changes of the mulberry paste product quality during storage. The sugar content in the standard formula was replaced by 10% w/w glycerol and 90% w/w of maltitol and maltodextrin mixture (20:80 w/w). The final mulberry paste product consisted of mulberry, maltodextrin, maltitol, glycerol, salt and citric acid by 69.80% 21.62% 5.40% 3.01%, 0.17% and 0.07%, respectively. The chemical compositions: carbohydrates, proteins, fat, ash, fiber, and moisture, of the product were 76.92% 2.39% 0.14% 4.19% 4.30% 12.06%, respectively. The total energy by calculation was 318.50 kcal/100 g. The anthocyanin content was 68.32 mg cyanidin- 3-glucoside/g. Total titratable acidity (citric acid equivalent) was 0.60%. The reducing sugar and total sugar values were 1.74% and 3.90%, respectively. The consumer acceptance as evaluated by untrained panelists was in the level of moderately like (7 score). The product packed in glass bottle containers was stored at 27±2 ºC for 4 weeks. The aw was increased while the textural properties: hardness, adhesiveness, and chewiness, were decreased. The chemical quality analysis showed significant decreases (p≤0.05) in the moisture and the anthocyanin contents. The microbial quality; total plate count and yeast and mold measurements were significantly increased (p≤0.05), however, the values were within the acceptable range according to the Thai community product standard (35/2558).Rajamangala University of Technology Phra Nakho

There are nutrients and high antioxidant properties. Riceberry broken rice (RBR) is a by-product from the rice milling process and has a low value. It can be processed into various products. The purpose of this research was to study the ingredients and the ratios for tablet formulations, including RBR powder, milk powder, whey protein, icing sugar, strawberry powder, bulking agent, anticaking agent and lubricant agent. Tabletting of powders was performed using a rotary tablet press machine. It was found that the powder products exhibited passable flow with the Carr Index of 24.57-32.10% and the Hausner Ratio value of 1.33-1.47. The water activity value of product was in the range 0.36-0.45. The tablets had thickness 3.86-4.38 mm, diameter 13.07-13.35 mm and weight 0.62-0.71 g/tablet. The increase of RBR powder content (10% - 40%) decreased hardness value of tablet products about 5 times (from 64 N to 12 N). Sensory evaluation of products in appearance, color, texture, odor, flavor, hardness, dissolution in the mouth and overall liking were conducted using 9 - point hedonic scale with 30 untrained panelists. The results showed that the optimal tablet formulation consisted of 30% RBR powder, 30% icing sugar, 18% milk powder, 1% anticaking agent, 1% lubricant agent and 20% bulking agent or strawberry powder. They showed the highest overall liking scores in ranges of “like slightly” to “like moderately”Rajamangala University of Technology Phra Nakho

process with potassium hydroxide (KOH) and a microwave heating process, which consumes less
energy and provides more rapid and uniform heat distribution than a conventional heating. The
obtained activated carbon was then characterized with BET, SEM and FTIR. It exhibited a large
specific surface area of 1,631 m2/g, and a total pore volume of 1.124 cm3/g consisting of mesopore and micropore. In addition, the active functional groups were also found on the surface of the activated carbon. Thus, it was brought for the adsorption test with methylene blue. It was found that the adsorption capacity of the activated carbon increased with time and reached the
equilibrium within 8 hours. The adsorption data of the activated carbon were corresponded to
Langmuir isotherm with the highest adsorption capacity of 370.37 mg/g. The adsorption kinetic of
the activated carbon exhibited pseudo-second order reaction suggesting to the chemisorption
phenomenon. From the thermodynamic study, it revealed that the adsorption process were
endothermic and spontaneous reactions.Rajamangala University of Technology Phra Nakho
