The objective of this research was to study the feasibility for producing the dry Dioscorea hispida powder as a thickener. The product was investigated in their properties the compatibility with dye and chemicals in print paste color appearance by indicated with color hue value the time durability storage the residual substance after washing treatment and the color fastness in washing and rubbing methods. The results shown the dry Dioscorea hispida powder was used as thickener that it was the good characteristic like the famous textile printing thickener as alginate. The dry Dioscorea hispida powder thickener was 10%w/w had the equivalent viscosity as 8%w/w alginate. It had 3 days stability storage and good compatibility for direct dye reactive dye acid dye and disperse dye print pastes. The color appearances were corresponding with owned hue in color index databases. The thickener was completely in washing process. And the washing and rubbing fastness were good to excellent.

This study was undertaken by using 10x10 m2 sampling plots chosen by stratified random sampling from 3 areas 50 plots for each area. Height and diameter of all trees with girth breast height (GBH) stem > 15 cm were measured. Aboveground biomass was estimated by allometric equation and the carbon stock was calculated by multiplying biomass value with conversion factor of 0.47. Result founded 4 tree species in 4 families. The Melaleuca cajuputi Powell had quite high density of 2091.31 tree/ha and other species found in some areas are Mitragyna brunonis Craib. Barringtonia coccinea Kostel. and Symplocos ferruginea Roxb with the density of 4.67 2.67 and 2.00 tree/ha respectively. Amount of aboveground carbon stock was 26.27 tonne C/ha. Mostly stem had higher carbon stock than branch and leaf at 19.92 4.94 and 1.62 tonne C/ha respectively. Average value of biomass carbon was 86.77 bath/ha.

The purposes of this research are to study and improve the productivity process of washing tables by setting standard time a case study of stainless manufactories. Nowadays the manufacturers don’t know the production capacity. That leads to the problems of manufacturers’ work control and late product delivery to the customers. The study is proposed to improve work procedures by designing operation process chart (OPC) the setting of operation stations Operation process chart time (OPC TIME) and finding the standard time in product manufacture. As for the operation process and the standard time setting the research revealed that the standard time of welding station in assembly process for the frame table sink tap nozzle high neck sink flick and welding station of all assembly parts were the first the second the third and the fourth respectively. The researchers’ suggestions were to add 2 welding machines and 2 workers in assembly process so as to work more efficiently so that it can decrease the total processing time from 855.24 minutes/set to 645.91 minutes/set or 24.47 % reduction.

This study examined the efficacy of two sanitizers; peroxyacetic acid (PAA) and sodium hypochlorite (NaOCl) in reducing total microbial counts on the carved leaf-shape surface of five types of fruits and vegetables: pumpkin carrot radish cantaloupe and Japanese cucumber. The samples were dipped for 3 or 5 min in various concentrations of PAA (40 60 or 80 mg/L) and NaOCl (50 or 75 mg/L) with distilled water as the control. After dipping the samples were drained for 5 min and the total plate counts were determined in triplicate. Dipping in 60 mg/L of PAA for 3 min was the best treatment for reducing microorganisms on the surface of carved carrot and radish; and 80 mg/L of PAA for 5 min was the best treatment for reducing microorganisms on the surface of carved pumpkin cantaloupe and Japanese cucumber. PAA at concentration 60 -80 mg/L showed potential as an effective sanitizer for carved fruits and vegetables more so than both concentrations of NaOCl.

The purposes of this research were to investigate elements that are essential for the learning environment of creative education on social network to develop creative thinking. The research methodology was documentary research. It was found that there were 3 major elements and 17 sub-elements which were essential for learning environment of creative education on social network to develop creative thinking; namely 1) Creative thinking development or learning process included six steps: (1) problem finding (2) data acquisition (3) analysis (4) solution finding (5) revise/evaluation (6) acceptance finding and (7) convergent thinking; 2) Resources or learning environment included four elements: (1) learning media (2) technology media (3)context and (4)communication; 3) Technologies or online social network in learning environment consisted of six elements: (1) identity network (2) creative network (3) interested network (4) collaboration network (5) gaming/virtual reality and (6) peer to peer communication network.
