The purpose of this research was to construct the appropriate forecasting model for the export values of alcoholic beverages using three-time series analysis methods including Box-Jenkins method damped trend exponential smoothing method and combined forecasting method. Time series data from the website of Office of Agricultural Economics with total 199 months from January 1998 to July 2014 were used and divided into two series. The first 192- month data from January 1998 until December 2013 were used to build the forecasting models and the last 7-month data from January to July 2014 were used to compare the forecasting method accuracy via the criteria of the lowest mean absolute percentage error and root mean squared error. Research findings indicated that for all forecasting methods that had been studied combined forecasting method was the most accurate method and this model was when and represent the single forecasts at time t from Box-Jenkins method and damped trend exponential smoothing method respectively.

Earthworms play an important role in the cycling of plant nutrients turnover the organic matter and maintain the soil structure. The decomposition of different types of organic substrates (household waste agro-residues and sludge) is able to be turned into valuable vermicompost. The percentage of nitrogen phosphorous and potassium in vermicompost was found to increase on different types of organic waste. Vermicompost is a finely divided peat like material with high porosity good aeration drainage water holding capacity microbial activity enriching of nutrients and buffering capacity thereby resulting the required physiochemical characters congenial for soil fertility and plant growth. Vermicomposting is a low-technology environmentally-friendly process used to treat organic waste. Moreover certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end product. The Earthworm species Pheretima peguana were especially used in Thailand.

The purpose of this research was to construct an appropriate forecasting model for the export quantity of frozen and chilled chicken using three time series analysis methods including Box-Jenkins method Holt’s exponential smoothing method and damped trend exponential smoothing method. Time series data from the website of the Office of Industrial Economics with total 130 months during January 2004 to October 2014 were used and they were divided into two series. Fristly 120 months from January 2004 to December 2013 were used to build the forecasting models and lastly 10 months from January until October 2014 were used to compare the forecasting methods accuracies via the criteria of the lowest mean absolute percentage error and root mean squared error. Research findings indicated that all forecasting methods that had been studied damped trend exponential smoothing method were the most accurate method and showed the forecasting model as where m represented the number of periods to forecast ahead with the starting value was January 2014 (m = 1).

This research aims to study the using a rubber sheet instead of the sulfur-capping accordance with ASTM C 617 in the compressive strength of concrete testing. The three of the compressive strength of concrete i.e. 180 240 and 320 ksc were the scope of study. The test results showed that the concrete with using a rubber sheet (fc (3)) had higher compressive strength than the standard concrete with sulfur-capping (fc (2)) at 7.7%. Therefore the adjustment factor from using a rubber sheet instead of the sulfur-capping in the compressive strength of concrete testing was 0.923; the compressive strength of concrete is equivalent to the standard testing. The relationship of compressive strength of concrete between fc (2) and fc (3) is fc (2) = 0.88 fc (3) + 12.04 with a correlation coefficient (r) of 0.988.

This paper discusses the mixed alloy silver pink by spending innocent Alloy capital ratio of 58.00% and check the analysis of color against Silver 925 under the metal content of about 58.40% alloy 41.60% result. According to the study the researchers used to hold above ingredients prototype to develop a mixture of silver to feature pink by analyzing the color (Color Analysis) tested the color of silver mixed pink capital ratio of 116.80 alloy. 83.20 wt.% has a shiny bright color space the L 67.17 a = 9.60 b = 2.04 a compound that can be used to produce silver mixed pink. In the manufacturing industry has for the user.
