The purposes of this research were to investigate anaerobic digestion of concentrated food waste in biogas production system at mesophilic temperature (37 C). The effect of grinding and pH controlled at 6.20 and 7.00 on methane production were also studied. It was found that the ability of mix bacteria which had initial concentration of 2100 mg/l for digesting concentrated food waste with grinding was higher than that without grinding because of the increase in surface area (about 1.37 time). In this system the optimum condition for bacteria growth was found at pH 7.00. Under optimal condition the digestion efficiency in term of chemical oxygen demand (COD) removal was 18.81% higher corresponding to an increase in methane production rate (19.10%) than other conditions

Thailands food processing industry is a important driving force in the economy of the nation. Their attractiveness of the industry dynamically generated employment and the intensity of competition at the same violence that increased its competitive advantage in the industry its important to bring the success and survival of a business.

The purposes of the study on service quality influencing behavioral intention of Government Housing Bank users (headquarters) were to explore opinions behavioral intentions and service quality that influenced the Government Housing Bank (Head Office) users’ behavioral intention. The samples used in this study were 222 customers who came to the Government Housing Bank from 9.00 am to 11.00 am and 1.00 pm to 3.30 pm. They were chosen by the systematic sampling method. The statistics used for data analysis were frequency percentage mean and standard deviation. The hypothesis was tested with correlation coefficient (R) and regression analysis at significant level of 0.05. It was found that Government Housing Bank (headquarters) users were mostly females between 31 and 50 years old with bachelor degrees working for the state enterprise and earned the average monthly income over 30000 Baht. The level of the quality service was high revealing the service with attention trustworthiness reliability and intention. Tangible services and behavioral intentions were at a high level including the buying intention word-of-mouth behavior complaint behavior factors on price sensitivity and the service quality which influenced the behavioral intention of the government housing bank (Headquarters) users at the 0.05 level of significance.

The purposes of the case study on relationship of good governance and work efficiency of operational personnel at National Food Institute were to study 1) the perception of good governance in the workplace 2) the level of perceived work performance and 3) the relationship between good governance perception in working and work performance perception of 153 operational personnel at National Food Institute. The research instrument used in the study were questionnaire yielding data processed and analyzed by statistics including frequency percentage mean (μ) and standard deviation (σ). The research revealed that 1. The level of perceived good governance in the workplace of National Food Institute personnel in the overall picture was especially high showing moral aspect responsibility aspect transparency aspect worthiness aspect engagement aspect and rule of law aspect respectively. 2. Performance perception level of National Food Institute operational personnel in the overall picture was especially high resulting in quality of work initiative or creative knowledge about the job respectively. 3. The results of hypothesis testing revealed that the level of perceived good governance was positively and highly related with the performance level of National Food Institute operational personnel in the overall (ρ = .702) statistically significant at 0.01 level. Perceived performance in each aspect was positively related to perceived overall work effectiveness revealing average relationship between worthiness aspect engagement aspect responsibility aspect transparency aspect under average relationship between moral aspect and very low relationship between rules of law aspect. The research recommends that National Food Institute should promote the recognition of good governance especially with the emphasis on the rule of law which deals with regulations orders for it is very imperative. Trainings for example should be regularly held to create the personnel’s awareness thorough understanding and true awareness toward good governance for this will positively affect the personnel’s work performance accordingly.

The purposes of this research are to investigate 1) personal factors contributing to the longevity of elderly 2) the dietary behavior of long-living elderly and 3) the relationship between personal factors such as:gender age BMI and dietary behavior. The samples are 29 of long-living elderly with ages more than 80 years old living in Tambon Tha Phi Liang Muang district Suphanburi province. The long-living elderly must be able to answer the questions. The statistics used to analyze data in this research are frequency percentage and Chi-Square (χ2). The data were analyzed using statistical tools. As for thier dietary behavior it was found that most long-living elderly usually have five food groups:eggs UHT milk paddy morning glory cabbage watermelon papaya and vegetable oils. They purchased these five groups of food for consumption. Boiling was the main method of cooking. They usually stored food in the refrigerator to keep them fresh.
