A study of sawdust-produced fiberboards using lac as binder for furniture industry
There has been an extensive use of fiberboards in the furniture industry. Therefore materials containing glue are applied to develop these fiberboards. This research investigated sawdust-produced fiberboards using lac as the binder and aimed to; (1) study the appropriate mixture proportions of sawdust and lac as the binder and; (2) explore the physical and mechanical properties of different mixture proportions of sawdust and lac at 5 wt% 10 wt% 15 wt% 20 wt% 30 wt% and 40 wt%. The research methods involved selecting sizes of dried sawdust and grinding with lac and alcohol. Then the mixture was pressed in a hot-pressing machine. After that the produced fiberboards were tested using medium-density fibreboards Thai Industrial Standard (TIS 966-2547) in a laboratory. The results showed that the appropriate proportions was 15 wt% which met the standard defined in Thai Industrial Standard (TIS 966-2547). The fiberboards could replace medium-density plywood and could be used in furniture and the home decorative product industry.

The purpose of this study was to produce catfish Som-fug for compare some characteristics between and three commercial brands of Som-fug (brand A B and C) which produced from other fresh water fish as a guide to develop Som-fug from catfish. For physical properties catfish Som-fug were 3.54±0.20 cm (width) 6.38±0.25 cm (length) 1.34±0.10 cm (height) and 2.50±1.4 g (weight) which is similar to that of brand C. Color analysis of un-fried catfish Som-fug showed light color that L* was 70.78±0.13 a* and b* were 5.06±0.53 and 11.50±0.31 respectively. Hue value was 74.42±0.25 value and chroma were 6.84±0.39 and 16.20±0.11 respectively. Som-fug from different brands were different in term of texture. The gumminess and chewiness values were significantly higher in brand B (p≤0.05) whereas the hardness and springiness did not differ significantly among the four different brands (p>0.05). For physio-chemical properties Som-fug produced from catfish had 1.70 % total acidity pH value was 4.50 and moisture content was 70.28% which was not different from that of brand B. However aw value did not differ among all of the Som-fug (p>0.05). The microbiological quality of the four Som-fug products analyses revealed the presence of Salmonella spp. Staphylococcus aureus Escherichia coli and mold count not more than standard (Thai Community Product Standard 471/2555) except brand B and C mold count was more than 100 CFU/g. For Sensory evaluation no differences in color flavor and taste were observed between catfish Som-fug brand A and brand B (p>0.05). Whereas catfish Som-fug gained the highest score in texture attribute which no differ from brand C (p>0.05).

In this paper proposed remote sensing using Normalized Difference Vegetation Index from NOAA STAR cluster value from k-means temperature rainfall number of rainy days and runoff to create runoff prediction model using Artificial Neural Network (ANN) and evaluated runoff models with the R2 and RMSE. The results show that the using of cluster value with other parameters to create predictive models can enhance forecasting results. When using Normalized Difference Vegetation Index with temperature value at lag time 1-2 month and cluster value at lag time 1 month to create model with ANN we have got the best performance which are RMSE=0.09 and R2=0.743. The experimental results shows that remote sensing data and cluster value from k-means can be used to predictive the runoff effectively.

The objective of this research was to study the optimal supersaturated temperature of palm sap powder by heating at 3 different temperatures (120 125 and 130 ºC). The initial sap contained moisture content pH and total soluble solid by 86.63% 6.84 and 15.5 ºBrix respectively. The result showed that the optimal supersaturated temperature of palm sap powder was found to be at 120 ºC. This powder had the yellow-light brown that contained L* a* and b* color value of 68.85 5.39 and 23.74 respectively. While the total soluble solid and Aw of this powder contained 84.84 ºBrix and 0.6 respectively. The sensorial evaluation was accepted in range of like moderately level (p≤0.05). The total microorganisms were 3.6x102 CFU/g and the yeast and molds were 10 CFU/g in which microbiological quality of this product was in standard of dried foods. This study pointed out that supersaturated technique can be utilized in palm sap powder production.

Thailands food processing industry is a important driving force in the economy of the nation. Their attractiveness of the industry dynamically generated employment and the intensity of competition at the same violence that increased its competitive advantage in the industry its important to bring the success and survival of a business. Earlier this competitive advantage has been studied and discussed widely both a cost advantage and the advantage of making a difference products and services. Currently there are more studies on the part of the competitive advantage that is consistent with the competitive situation that is highly dynamic. In this study was to review the literature that relevance to the dynamics competitive advantage in the food processing industry in Thailand. Therefore this article is useful for entrepreneurs executives in food processing industry as well as for the scholars who are interested in this line of research.
