Currently the toy manufacture is beginning to be interested in greenhouse gas or carbon dioxide equivalent release reduction. Because this is one to way to encourage production cost environment trouble and organization image valve efficiently. The receivable standard for evaluation is carbon footprint for Organization CFO. So this research has objective to study opportunity for initiate CFO in Toy Manufacturing plant case study this CFO is able to evaluate energy consumption and GHG release systematically. This can be used to prepare plan of energy consumption reduction management and reduce GHG release of efficiently. This research was study energy consumption and GHG release by using database of 2010 we found that plant case study was released carbon dioxide 8500 tons CO2 carbon dioxide equivalent by calculated into Scope 1 = 1249 tons CO2 Scope 2 = 6948 tons CO2 equivalent and Scope 3 = 304 tons CO2 equivalent. So the result from this research is being uses important information for planning energy consumption reduction and GHG release of sustainable case study.

Factors affecting successful implementation of balanced scorecard of companies in Bangkok Metropolitan
Factors affecting successful implementation of balanced scorecard of companies in Bangkok Metropolitan

The purposes of the study were to explore success of the organizations which applied Balanced Scorecard to assess the performance and also investigate factors affecting successful implementation of the balanced scorecard of companies in Bangkok metropolitan. The data were collected from the samples which were organizations in production industry registered with Federation of Thai Industries up to 2010 by means of 400 copies of the questionnaire and analyzed by the frequency distribution percentage distribution standard deviation Pearson Product Moment Correlation Coefficient and Multiple Regression Analysis. The result showed that factors that influenced the implementation of the balanced scorecard in the organizations were factors regarding working process organizational structure and conflicts respectively.

The input power factor control of a carrier-based dipolar PWM  for matrix converters
The input power factor control of a carrier-based dipolar PWM for matrix converters

This paper presents the input power factor control of a modulation using a carrier-based dipolar for matrix converters by determining the optimum value of free parameters b and d in general solutions of the modulation matrix. The proposed PWM method is not only less complicated but can clearly show the coupling of the input power factor control from both active and reactive output power. The experimental results show that the proposed PWM method can control the conditioned input power factor set earlier

Development of Liquid Soap with Banana Peel Pulp. We have studied the process of developing a recipe and product processing pulp peel bananas: banana peel and pulp of 3levels which take data from a survey of consumer behavior to suit the application. Andhave studied the sensory quality of the products liquid soap mixed pulp banana peel on 3 levels 5: 48.6 10 43.6 and 15 38.6% indicated that test scores give the formula 2 (20:10). in terms of color homogeneity. And texture (thick) overall. Levels like moderately to like verymuch. In terms of cleansing and smell no different at a statistically significant (p> 0.05) werethen tested for quality physical found that Liquid Soap with Banana Peel Pulp Formula 10:43.6% of the color. lightness (L *) was 59.6 ± 0.01 redness (a *) was -0.42 ± 0.01 andyellowness (b *) were 1.31 ± 0.01 which liquid soap is opaque. Because of the banana pulp is mixed in liquid viscosity in the 2584 Point Centrino bubble volume 370 ml and the water chemistry. The pH value of 6.52 ± 00.1 in the pH range 5-8 Thai Community Product Standard. Microbiological quality The shelf life of the product liquid membrane banana: banana peel and pulp. Store in a sealed jar per piece. Kept at room temperature The products were analyzed analyzed microbiological quality. Therefore the total plate count And yeast and mold By sampling every 1 week for a period of 8 weeks the total plate count<10 (CFU / g) Clostridium spp. Was not found Staphylococcus aureus None Streptococcusspp. Did not find Salmonella spp. Did not find Pseudomonas aeruginosa is found Coliform bacteria less. 3 MPN per gram Escherichai coli has been found safe for consumption. The resort complying with (TCPS. 95/2552) is to be a Thai Community Product Standard LiquidSoap of bacteria must be less than 1000 colonies per gram. Or cubic centimeters Meet ThaiCommunity Product Standard Liquid Soap education acceptable to the liquid membranebanana: banana peel and pulp were found to have a moderate satisfaction. Irritation andfeeling 100 percent.

Preparation of titanium dioxide supported on activated carbon
Preparation of titanium dioxide supported on activated carbon

The purpose of this research work was to synthesize titanium dioxide supported on activated carbon and used it as a catalyst for dye decolorisation. The effect of preparing factors on titanium dioxide supported on activated carbon such as calcinations temperature and the amount of carbon supports were investigated at 300 400 and 500OC and in range of 5-30 percent by weight respectively. The X-ray diffraction (XRD) technique was used to detect the crystal structure of prepared catalysts. It was found that all peaks were anatase phase. The morphology of these catalysts was analyzed by scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques. The results showed regularly distribution of titanium dioxide supported on activated carbon. The particle size of obtained catalysts was 5-10 nm. The Brunauer-Emmett-Teller (BET) technique was analyzed physical characteristic of catalysts. The specific surface area average pore diameter and pore volume of catalysts was 151.02-784.13 m2/g 26.94-64.35 and 0.24-0.55 cm3/g respectively. Furthermore the activity of obtained catalyst was carried out by using these catalysts to decolourise dye aqueous solution. The titanium dioxide supported on activated carbon 20 percent by weight can obtain 99.78% decolourisation at dye concentration 75 mg/L catalyst concentration 0.5 g/L within 90 minute. Comparison with titanium dioxide P25 (commercial grade) titanium dioxide supported on activated carbon has higher ability. This is because it was not only photocatalytic reaction but it was also absorption
