Silica is an amorphous and nanometer scale voids and porous form of silicon dioxide. As long known for its high specific surface area synthetic silica has been used to adsorb water readily and applied for keeping many biological products dry protecting equipment from moisture damage. In the study the researchers have interested in making the tentative eco-friendly dehumidifying products based on the silica extract from bamboo leaves. The extraction procedures were performed by boiling dry bamboo leaves with various concentrated hydrochloric acid (HCl) at 1 2 3 and 4 M then burning them at 650oC for 4 hr before analyzing the purity of the biosilica with the X-ray Fluorescence Method. The results showed that the highest purity of the biosilica sample at 96% could be obtained after treated with 4 M HCl comparing with the control commercial silica. By hygroscopic test the extracted biosilica with 2 M HCl showed the highest moisture absorption properties close to the commercial silica. While the highest adsorption capacity was found in the biosilica sample treated with 3 M HCl. The dehumidifying efficiencies of all HCl treated biosilica power were not much different comparing to the commercial silica gel. Instead of using synthetic silica therefore this high environmentally friendly and cheaper biosilica from bamboo leaves can preferably be decent and further applied in green industry.

At present most human-related products contain a mixture of chemicals for inhibiting microorganisms polluting the environments and harming the users. The purpose of this research was to develop a product using banana and papaya peel extracts as replacers for the chemicals inhibiting microorganisms in heel cream. By extracting raw bananas and papaya peels with coconut oil the studying the efficacy of inhibition on E. coli S. aureus Aspergillus sp. and S. cerevisiae with Disk Diffusion method at the protein concentration were performed as follows: 25 50 100 and 150 micrograms per milliliter. The observation of clear zone to observer clear zone of inhibition. and the Turbidity method using light absorption at a length of 600 nm was also were shown the corresponding results of microbial inhibition. observed and showed the consistent results. Especially the papaya extract having the protein concentration at least of 150 micrograms per milliliter could inhibit all 4 microbe species but could not inhibit S. cerevisiae that indicated a good trend of no harm on human. When mixing the extract in the heel cream it was found that Heel cream containing banana extract papaya and both mixtures displayed the density of 0.9674 0.9103 and 0.8057 gram per cubic meter respectively. They could be stored at room temperature for more than 45 days and still maintained the properties of microbial inhibition by up to 80 percentages. When studying the satisfaction of consumers collected randomly from teenagers to elders at both sexes of 40 people more than 80 percentages of the customers were satisfied with the heel cream from all extracts. These all creams could make the feet soft and moisturized within 1 week. More suggestions were to improve the smell of heel cream products to be suitable for all age of consumers. Therefore this research could be concluded that banana and papaya peel extracts inhibiting microorganisms could be used as a heel cream for further continuously developing at the industrial level.

This study aims to examine stress and factors in stress for employees in a public bank using questionnaire to collect data from the sample group consisting of 237 employees from a public bank. The hypothesis is analyzed by multiple linear regression. Result was: 1. Operational factors such as work description acceptance and accomplishment had positive impact on stress for the sampled bank employees. Operational factors constituted 40.30% of change in stress for the sampled group 2. Organizational factors such as work structure and relationship with colleagues likewise had positive impact on stress for the sampled bank employees. Organizational factors represented 34.30% of impact on stress for the sampled group.

The objectives of this research were to study 1) the marketing mix factors of choosing derlers of Japanese imported wind instruments 2) consumer loyalty of choosing derlers of Japanese imported wind instruments and 3) to study the influence of marketing mix factors in choosing derlrs of Japanese imported wind instruments. The sample group was 240 consumers who chose to use sales representatives Japanese imported wind instruments. The questionnaire was used to collect data in the metropolitan areas. The data were analyzed using statistics including frequency percentage mean standard deviation and multiple regression analysis which was applied to test the hypothesis. The study result indicated that most respondents were males aged between 31 - 40 years old working as engineers earning monthly income averaged between 20001 - 40000 baht. The marketing mix factors of Japanese imported tools dealers in terms of the distribution channel was considered highest followed by the price process personnel product physical characteristics and the marketing promotion respectively. Regarding the consumer loyalty in choosing Japanese imported wind instrument dealers the highest was word of followed by the price sensitivity purchasing intention and claim behavior respectively. The hypothesis testing reveal that the marketing mix factors in terms of price did influence the loyalty in all aspects namely word of mouth purchasing intention price sensitivity and claim behavior. Therefore the hypothesis was accepted. The marketing mix factor related to product had no influence on loyalty in every aspect such as word of mouth purchasing intention price sensitivity and claim behavior. Therefore the hypothesis was rejected. The marketing mix factor related to the process and price that influenced the consumer loyalty towards word of mouth in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to price sales staff and distribution channels influenced the consumer loyalty in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to price sales staff and process influenced the consumer loyalty and price sensitivity in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to the physical characteristics price and marketing promotion influencing consumer loyalty claim behavior and promotion in choosing dealers of Japanese imported wind instruments.

This investigation aims to developing a recipe for making Gleb-Lum-Duan (Thai shortbread cookies) with black sesame from gluten-free flour by determining the appropriate ratio of glutinous flour to rice flour. According to the results from sensory quality evaluation of 50 panelist who were ordinary people using the nine-point hedonic scale it was found that Gleb-Lum-Duan having the ratio of glutinous flour to rice flour as 40:60 had the highest acceptance rating among the tasters. The results from adding texturizing additives in the gluten-free Gleb-Lum-Duan showed that the tasters panelists gave the highest acceptance rating for Gleb-Lum-Duan which xanthan gum on flavor smell texture (fracturability) and overall preference. For the amount of black sesame added in gluten-free Gleb-Lum-Duan the panelist gave the highest acceptance rating for Gleb-Lum-Duan which included 20% black sesame based on color smell taste texture (fracturability) and overall preference. For color of product the L* a* and b* values were 68.83 0.09 and 6.97 respectively. Increasing the amount of black sesame resulted in increasing a* value and decreasing b* value. The amount of free water differed significantly (p≤0.05). Increasing the amount of black sesame was found to decrease hardness (p≤0.05). Gleb-Lum-Duan with black sesame from gluten-free flour included carbohydrates protein ash fat and moisture of 63.69% 3.01% 0.95% 31.19% and 1.16% respectively. A group of 100 ordinary consumers identified taste and nutritional value of gluten-free Gleb-Lum-Duan mixed black sesame as the most important factors
