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. The relationship between personal factors and dietary behavior could be classified into 5 areas : types of food frequency of consumption sources of food methods of cooking and methods of food preservation. The finding found that gender age and BMI were related with food consumption. However cooking (boiling) was not related with statistically significant level at .05.

The objectives of this thesis were to study 1) Eating knowledge 2) satisfaction in the Food Shops at Queen Sirikit National Institute of Child Health (QSNICH) 3) food consumption behavior 4) T Relationship of eating knowledge and food consumption behavior 5) the correlation between satisfaction in the Food Shops at QSNICH and food consumption behavior. The study was conducted with 315 staffs QSNICH who served in the Food shops at QSNICH. The research instruments used were the personal data questionnaire. Data analysis was presented in frequency average standard deviation and Pearson’s Product Moment Correlation Coefficient. Results indicated that average scores as calculated by mean percent for eating knowledge was shown at good level. Most of the staffs had medium level satisfaction of food shops and the food consumption behavior was shown at sometime level. In terms of the relation of eatting‘s knowledge and food consumption behavior there was no significant associations. In addition the correlation between satisfaction in food shops at QSNICH and food consumption behavior had no significant association. The suggestion for this research was to promot activity to change food consumption behavior to increased eatting healthy food.

The purposes of the experimental project were to modify (FBSF) to compare plastic media form Small Pall Ring Bio-media Filter are commercially available. The model of FBSF consists of Equalization tank (EQ) Aeration tank with . The corresponding with Hydraulic Retention Time (HRT) 48 hrs. The factors used in the study are the essential parameter such as BOD COD SS TDS and changes in the Physical Characteristics of wastewater. polypropylene as a supporting media for Fixed Bed Submerged Filter polypropylene media 2 tanks Aeration tank with plastic media 2 tanks and Effluent tank The result experimental indicated that efficiencies of FBSF with 92.78% 75.90% 96.75% and 20.76%0 respectively gave the higher effluent values that the plastic media the efficiencies 84.20% 61.66% 94.12% and 14.80% 0. The effluent BODwas less than 20 mg/l. The was on clear less sediment no foul odor.

The experiment was investigated the ability of the natural sedimentation to reduce amount of organic compound in household wastewater including removal mechanisms of organic compound in household wastewater by sedimentation. Sedimentation used in this experiment were collected from klongpremprachakon in 2 locate are as follows; in front of Watsamiannari and in front of train station Bangkhen. The experimental sediment bring it from area actual and sediment has autoclaved for analysis organic compound included BOD value COD value and organic matter by variation of time testing 3 5 12 and 24 hour respectively. The research result found that the experimental 24 hour Amount of organic compound in terms of BOD COD concentration and organic matter retained in household wastewater quite low. The natural sediment redound to adsorption and biodegradation by microorganism was reduce amount organic compound included BOD value COD value and organic matter better than inactivated sedimentation by autoclave.

The research aims to investigate the problems and needs of the Lat Mayom Floating Market community in order to find ways to develop the market and improve the ability of tourism stakeholders to welcome foreign tourists. The research methodology was qualitative and data was collected by means of in-depth interviews with 20 tourism stakeholders in Lat Mayom Floating Market and a focus group discussion with 6 of these stakeholders. The research results indicate that Lat Mayom Floating Market is centred on agricultural tourism that presents the Thai way of life. The research identified several problems faced by floating market stakeholders including: difficulty in communicating in English; lack of tourism facilities to welcome tourists in the area of the floating market; and inadequate transfer of local wisdom and knowledge of tourism management to the younger generation. Due to these problems the participants stressed the need to receive training to develop their English and tourism management skills as well as the need to improve tourism facilities at this tourist site. Possible solutions to these problems identified by the research results include a project to train locals in many topics such as basic English for tourism service techniques to welcome tourists and knowledge of sustainable tourism management. The target group of this project should be locals who live in the area of Lat Mayom Floating Market. It is important that the training program be long-term to enable locals to practice English that can be used in real situations. Participants suggested that such a program could be organised by volunteers or by the government. Recommendations for developing Lat Mayom Floating Market include raising the awareness of both locals and tourists about conserving the environment and tourist safety (especially when taking boat rides); and preserving authentic culture of locals by developing only the tourism facilities (e.g. public toilets) that need to be improved not ง developing too many facilities such as parking lots or accommodation in order to limit the number of tourists to ensure the sustainability of Lat Mayom Floating Market.
