Nitrogen is an essential nutrient for plant growth. When the plants have been grown for a long-term effect to decreased nitrogen in soil and insufficiency of the plant growth. One biological method for increasing the nitrogen content in soil is utilize of free nitrogen-fixing bacteria Azotobacter. Therefore the objective of this research was to search natural material suitable for Azotobacter fixation. The 10 natural materials were observed physical structure and investigated the ability of natural materials for Azotobacter fixation. The results showed that water hyacinth and bagasse stalks were fixed the Azotobacter of 2.43x108 and 1.94 x108 CFU per gram of each natural material respectively. After that the selected fixed Azotobacter of water hyacinth and bagasse stalks were studied the growth of Brassica Chinensis. This experiment was designed to 4 treatments. The first treatment was mixed of water hyacinth stalks and the Azotobacter. Second treatment was mixed of bagasse stalks and the Azotobacter. The third treatment was the Azotobacter only. The last treatment was soil only. The results indicated that the average of plant growth include height leaf number root length fresh weight and dry weight of the mixed of water hyacinth stalks and the Azotobacter had significantly higher growth rates than other treatments. The total nitrogen was also increased 1.4 fold in the soil. All results suggest that the water hyacinth stalk is alternative for the fixation of the free nitrogen-fixing bacteria Azotobacter as induce nitrogen in the soil and plant growth promotion.

The research team aimed to develop the cracking and extracting processes for Ganoderma lucidum (Red Lingzhi) spores and transfer the technology in the form of soap bar and liquid products together with the cracking and extraction process to the community at Farm Haid Klang Ban in Pathumthani Province. From the study since higher more bioactive compounds found in the aforementioned Ganoderma (Lingzhi) spore extracts over its basidiospore itself the optimized breaking and extraction procedure were composed of freezing at -20oC for 2 days bead beating for 5 minutes and then spore fermented with Lactobacillus spp. at room temperature for 24 hours. The processes could provide more than 65 percentages of the spore fracture efficiency and obtain more active substances such as polysaccharides and triterpenoids Moreover the spore extraction process was required by shaking in ethanol dissolved in distilled water at the ratio 80:20 for 2 hours. The obtained bioactive Lingzhi spore extracts as one active ingredient was added into the saponification process to make soap bar and liquid product. It was found that the soap products could create satisfaction and good feedback from high-level consumers of the farm community in Pathumthani Province. The research should therefore be successfully applied in the form of commercial red lingzhi extract soap in the manner of integration of science and community with knowledge of efficient Red Lingzhi spore cultivation and separation. It can help the development of community enterprises can bring up sustainable economic development in the country in the future.

The purposes of the study were to investigate 1) the opinions towards internal organizational factors affecting organizational commitment of DENSO Tool & Die (Thailand) Co. Ltd. employees 2) the organizational commitment and 3) the influence of factors affecting the performance of DENSO Tool & Die (Thailand) Co. Ltd. Employees. The data were collected from the employees through a questionnaire used as the research tool on organizational factors affecting organizational commitment and analyzed through parameter value percentage mean score (μ) standard deviation (σ) Spearman rank Correlation Coefficient or Spearmans rho and stepwise regression. The findings revealed that the internal factors affecting the commitment of the employees working at DENSO Tool & Die (Thailand) Co. Ltd. were positively related at the .01 statistical significance.

The purposes of this research were to Guidelines for design and development of products processed woven from sedge professional groups Ban Wa Wa Ban Muang Khon Kaen. Sample group in research is foreign tourists 50 people and Local people 50 people. Wants to buy processed of products processed woven from sedge professional groups Ban Wa Wa Ban Muang Khon Kaen. Tool used in research is a questionnaire want side different of the target audience have confidence equal to .930 statistical analysis was performed by percentage. Average mode and questionnaire to evaluate satisfaction in the field of use and in marketing processed products from woven reeds in the process evaluation choice and in the evaluation process compare with the original souvenirs by the questionnaire 2 copies have confidence equal to .830 and .784 respectively. Statistical analysis was performed by means of percentage mean and test the hypothesis with the t-test statistic type Dependent Sample. The research concludes that. 1. The processed product design woven from reeds method 1 suitable for buying relatives brethren. Method 2 suitable for buying in the family and Method 3 suitable for buying boss adults. 2. Select target group the processed product design woven from reeds in method 2. Statistically significant at the .05 level vendors are more satisfied than the original model in almost every aspect. 3. The target group is satisfied in processed products woven from reeds the new model is more than the original model on all sides and processed products woven from reeds powerful new applications rather than processed products woven from reeds original form.
