This research aims to study the application of kaolin with coconut fiber corncobs fiber and durian peel in concrete masonry unit wall for increasing effective heat protection and lightweight. The ratio of cement type 1: kaolin is equal to 1: 60 by weight. The kaolin is replaced by fiber include coconut fiber corncob fiber durian peel fiber with 1.67% 3.33% and 5% by weight of kaolin. The kaolin concrete block mixed with fiber sample size is formed to 6.9 x 39 x 19 centimeter with the hydraulic compactor. The samples tested in physical and mechanical properties follow the TIS 58-2533 standard. Resulting their fibers can reduce the density thermal conductivity and compressive strength and increase the changing length and water absorption of kaolin concrete blocks. The kaolin concrete block without fiber has highest compressive strength followed by the kaolin concrete block mixed with corn cob fiber the kaolin concrete block mixed with coconut meal fiber and the kaolin concrete block mixed with durian peel fiber has lowest compressive strength respectively. However their fibers have possibility to be composite materials to reduce weight of kaolin concrete blocks

This purpose of the research was to study of Solar Absorber Shape Effect in the Solar Air Heater. These has designed and constructed the solar air heater for drying agricultural products of two different types. Comparison of First thing used square type one glass layer used centrifugal fans to feed air and installed solar absorber which each made of sinusoidal corrugate galvanized steel sheet coated with dull black paint and each other made of trapezoidal corrugate galvanized steel sheet coated with dull black paint. The results of research showed that the solar absorber which each made of trapezoidal corrugate galvanized steel sheet coated with dull black paint is most suitable. Which has overall thermal efficiency 66% and can generate maximum temperature 96.13 degree of Celsius

To determine the impact of breakwater construction on fish assemblages larval and juvenile fishes were used to interpretation. The study was conducted in the inter-tidal zone constructed breakwater and natural sandy habitats of Pakmeng Beach at Sikao District Trang Province. The morphology of water bottom showed that differ between the front areas of breakwater construction and natural beach. The bottom profiles at in front of natural beach is seem to be deep immediately from shore and connect to a flat sand dune whereas in front of breakwater construction area was shallow and flatten. Fish assemblage data had showed the average number of larval and juvenile fishes no differ between the two habitats whereas the number of taxa of juvenile fishes was higher significantly in the inter-tidal zone of breakwater constructed area (Mann-Whitney U=11.5 p=0.017) Even though our study have revealed the application of fish assemblage data to asses the impact of constructed breakwater. Current study have limited on data collection not entire seasonal of larval and juvenile fishes abundance. Using our interpretations in other study sites is necessary to collected more frequency both beach morphological and fish assemblage changes.

Nowadays one of major problems of SMEs is improperly planning the production to serve for the true demand of customers. Therefore this research was set the objective to apply forecasting techniques to predict the right demands and feed them together with other constraints as inputs for the LP model in production planning to get maximum profit and also conform to the restriction constraints such as production processes sales volume labor constraints inventory and investment requirements. As a result from this study the Decomposition Technique by Minitab program was the most accurate technique for sales forecasting of Quilt Products of Hmon-Oon Group. The sales forecasting information was then used as input to a mathematical model (LP) targeting maximized profit processing by Solver program in Microsoft Excel 2010. Eventually the business can gain more benefit by using this method from 358830 Baht in one quarter to 504425 Baht or 40.57% increase. Cost of inventory decreases from 17764 Baht to 16670 Baht or 6.16% decrease. Production labor hours in one quarter decreases from 2984.12 hours to 2378.77 hours or 20.29% decrease

The objectives of this research are 1) to study usage behavior and satisfaction in the information technology of personnel in the Ministry of Culture. 2) To study the relationship of usage behavior and satisfaction of personnel in the Ministry of Culture towards the information technology. 3) To compare behavior of personnel in the Ministry of Culture in using information technology which different in demographic characteristics. 4) To compare the satisfaction towards information technology of personnel in the Ministry of Culture which different in demographic characteristics. The representative sample of this research is 250 personnel in the Ministry of Culture. In addition for this research questionnaire has been used as a statistical methodology. The result of this research implies that most of the personnel in the Ministry of Culture are female 74.4 % of them use and exposure into the information technology by using desktop computer and most of these people are greatly satisfied in the information technology. Moreover regarding the effective and fast intercommunication it has been found from the statistical hypothesis testing that the demographic characteristics differences such as gender age marital status education and average income per month have the differences in the usage behavior and satisfaction of the information technology and the usage behavior of the information technology has a relationship with satisfaction in using information technology of personnel in the Ministry of Culture.
