The purposes of this project were 1) to study the formula of Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour 2) to study the formula of Thong Ek (Gold Foil-Decoration)from Lotus Seed Flour and Lotus Stamen and 3) to study the nutrition facts the antioxidantand the detection of microorganisms test in Thong Ek (Gold Foil-Decoration) from Lotus SeedFlour and Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen. Thestudy found that the highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour was the formulation number 2. The highest average ofappearance color smell taste texture and over all of the participants’ satisfaction were8.52 8.48 8.52 8.60 8.54 and 8.60 respectively. The result of Duncan’s New Multiple RangeTest DMRT showed differences with statistical significance at the 0.05 level (p≤0.05) in all 3formula. The highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen was the formulation number 2 as well.The highest average of appearance color smell taste texture and over all of theparticipants’ satisfaction were 8.46 8.52 8.48 8.56 8.62 and 8.68 respectively. The result ofDuncan’s New Multiple Range Test DMRT showed differences with statistical significance at the0.05 level (p≤0.05) in all 3 formulations. In addition the nutrition fact test result in Thong Ek(Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration) from LotusSeed Flour and Lotus Stamen - 100 g. in dry weight found that the amount of energy and fatdecreased. In contrary the amount of protein fiber and carbon increased. When analyzed bythe FRAP (umoles TE) and DPPH (mg AA) the antioxidant and Polyphenol (mg eq GA) in theThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen increased withstatistical significance at the 0.05 level (p≤0.05). Finally the detection of microorganisms inThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration)from Lotus Seed Flour and Lotus Stamen test result found the E.Coli less than 3 and noneSamonella SPP.

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.

The objective of this research was to study formulas basic production process and nutrition value and consumer test of frozen Chaya vegetable cream soup. The results indicated that color aroma taste consistency and overall formulas 2 had scored higher than formulas 1 and formulas 3 (p≤0.05). Then formulas 2 was selected for the next step study. Comparison of old frozen Chaya vegetable cream soup formulas 2 and adjusted formulas 2 which according to expert advice by blending from 2 minutes to 4 minutes add unsalted butter add cooking cream and reduced pepper from 5 grams to 3 grams in terms of color aroma taste and overall liking are not different except the texture of the soup. Frozen Chaya vegetable cream soup has moisture 87.60% fat 1.45% crude fiber 1.84% ash 1.07% protein 1.11 % calcium 85.37 mg/kg iron 0.44 mg/kg potassium 128.34 mg/kg and total fiber 1.19 mg/kg. Frozen Chaya vegetable cream soup has light green color and cyanide substance still was 0.1 mg/kg which is safe for the consumer. Comparison of preference score between Frozen Chaya vegetable cream soup and non-frozen found that was no difference (p ≤ 0.05). The consumer test of them are female between 25-35 year old graduated bachelor degree a company employee and income 20001-25000 THB per month consumer from this group are satisfied with high scores for cream soup. The consumer is interested in frozen Chaya vegetable cream soup because this is a new product and price 45 THB is valuable. The consumer would like to have a frozen Chaya vegetable cream soup sole at the supermarket. The cost for the product per 1 cup is 19.07 THB and the sale price is 45 THB.

The study aims to study the change leadership that affects the organizational culture and work efficiency of the staffs at the operational level and to study the good governance principles that affect the organizational culture and work efficiency of operational staffs at Commercial Concrete Production Business Unit. The population used in the study is 200 operating staffs at Commercial Concrete Production Business Unit using questionnaires for data collection. The data analysis is conducted using descriptive statistics and inferential statistics. The result indicates that change leadership affects organizational culture of operational staffs with statistical significance at 0.05 level. It can predict the organizational culture of operational staffs at 16.30 percent. Good governance principles affect the organizational culture of operational staffs with statistical significance at the level of 0.05. It can predict the organizational culture of operational staffs at 29.50 percent. Change leadership affects the operation efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 13.80 percent and good governance principles affect the work efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 28.70 percent.
