The research in the aim for useless material from cashew nut shell produce are heating energy briquettes to use recompense energy fine wood and charcoal from natural. By the flour paste is join together pass procedure heating briquettes with hand press implement. It is cashew nut shell can make to burn with earthen stove high temperature stove and steel stove from cashew nut shell are still shape and have bring into fine crush machine receive dust charcoal. It is mixed dust charcoal with flour in ratio 5:1 (by melt flour into hot water one liter until flour paste) mixed and bring into heating briquettes with hand press implement receive heating energy briquettes are no broken. When we bring expose to the sun until dried. After that to test efficiency of heating energy to see that cashew nut shell can to produce are heating energy briquettes. It use heating energy in home family in community replace to use from fire wood and charcoal from natural and heating energy briquettes from cashew nut shell can to use a make cooking well no broken fire well and height heater. It is suitable to produce heating energy for to use home family communities or commercial production and industries are use heating energy from fire wood and charcoal.

The purposes of this research were to study demand forecasting and production planning. The case study company manufactured the fish sauce product that was made to stock. To design the system the sale data was studied in order to choose the appropriate forecasting technique for the sale data. After using the system with the company case study it revealed that the prediction system can forecast the production of 1126570 units in July 2008 whereas the total sales were 1134322 units. The difference was equal to 2718 units or 0.69 percent of the actual sales which was a total cost of 116280 baht which was more equivalent to the actual sales predicted by a sole experienced decision maker who predicted the production at 1274098 units. The difference was equal to 139776 units or 10.97% percent of the actual sales which mean 2096640 baht of total cost

What-If Analysis is a simply uncomplicated hazard indication method. Its analysis method is highly flexible by brainstorming of analytical team that have good knowledge and experiences for thinking about questions regarding undesirable events that might occur and cause severe incidents or accidents by the asking questions begin with “What If…..?” or “What would happen if…?”. This method can be used for any time and it will get highest benefits if it is used during the design process or improvement of existing systems because all systems will be improved to be more safety at early stage. Furthermore it is also suitable to identify hazards from dynamic activities such as car driving and cleaning etc. What-If Analysis includes 4 steps: establishing cope of questions setting analytical team studying information and related documentation establishing questions and finding effects. Analytical team should include at least landlord design engineer safety officer technician and maintenance technician and if this analysis method is used for only identifying hazard technically and if should beware of overlooking critical problems occurred from many related incidents

The purposes of this study were t~ investigate the influence of color psychology on low vision people affecting product design and to conclude color psychology applied for low vision people. The study comprised five points. First point was to study what colors that people with low vision could see clearest by ranking. Second point was to study what they liked the most colors. Third point was to study what complementary colors that they could see the clearest color by ranking. Fourth point was to study how the sample groups felt about colors.
