The purposes of this research were 1) to study organic rice production of Praknamdaeng Community Amphawa Samutsongkhram 2) to investigate explicit knowledge of organic rice plantation in Praknamdaeng Community and 3) to discover guidelines on promotion to grow organic rice for food security of Praknamdaeng Community. The population groups were agricultural government officials and Praknamdaeng’s farmers. The research tool was interview analyzed by content analysis. The results revealed as follows: 1) According to organic rice production of Praknamdaeng Community there were 288 hectares (1800 rais in Thai) rice-growing areas and 90 farmers’ families in villages 2 3 4 and 6. The land was full of clay not flooded and in the downstream irrigation area. The weather was humid because it was near the sea. There were many different types of rice varieties grown in Praknamdaeng Community namely; Khao Leuang Patew Chumphon Pathumthani fragrant rice RD 31 Suphan Buri 1 RD 59 RD 47 Sangyod Maung Phatthalung rice Aromatic Black (Hom–nin) rice and Riceberry rice. Rice farming process was mostly taught by villages’ ancestors or experts through learning by doing and working together. The problem of traditional rice growing was soil degradation. The organic rice cultivation in Praknamdaeng Community began in 2005. Khao Leuang Patew Chumphon the loca rice was highly grown. Nowadays 70 percentage of the land was full of GAP organic rice production. The biggest problem for the farmers in the community was drought. 2) As for the appropriate knowledge of organic rice production in Praknamdaeng Community the rice farming processes between traditional and organic rice growing were not different. In the case of organic rice production bio-chemicals were used as herbicides and pesticides but the amount of chemical substances was reduced and only used in a short period for safe. 3) Due to guidelines on promotion to grow organic rice for food security of Praknamdaeng Community there were some guidelines for the 2 groups: farmers and community. The guidelines for the farmers were 1) the pursuit of knowledge or transfer of knowledge to the farmers 2) establishing the learning center of organic rice production in the community by chemical-free cultivation 3) providing organic rice paddy demonstration plot for learning 4) preparing the local people to understand and be volunteers for organic rice cultivation 5) developing farmer organization and 6) promoting comprehensive marketing. The guidelines for the community were 1) in the aspect of the quality of life organic rice consumption has to be promoted for the local people and for food security in the future 2) in the aspect of promotion of farmer career organic rice products can be more value-added make pride and more money for the community 3) systematic community enterprise management 4) support for the networks of producers food processing and distribution of organic rice among other communities and provinces. In the aspect of food security the farmers firstly focus on farmer career stability because they consider it as one of the important careers to produce food to the society. Moreover standard qualified products and suitable demand and supply are included.

It is well known that waste spoiled are undesired and one of the main causing of environmental problems and health effects. In Thailand there are growing wastes especially at Thewarat market every year. The causes of the increase in wastes are from economic and industrial expansion which are important issues for the community responsible to manage and correct the amount and types of waste disposed properly before disposal. In the study a preliminary survey by talk and providing the questionnaires were conducted at the Thewarat market. It was found that solid wastes or rubbishes are mostly generated during and after trading process with and without proper can disposal. The stores did commonly dump the solid and liquid wastes around the stores or nearby the bin not inside the bin. The unpleasant observations shown were the solid wastes and dirty water contaminating into the soil and in the waterway and it was not managed hygienically. Uncared by unconcerned sellers during busy market during the day more unrecognized attitudes of the merchants themselves inappropriate placement of food and food waste in the public for the buyers and manucipal wastes generated by people in the surrounding community were normally observed daily. More risks of disease spreading and accumulated rodents insects and pathogens breeding and homing were appeared during at night after the market closed. In the research the campaign and suggestions were operated by the research team the proposed strategies for the waste management at Thewarat market area were including two times of training; discussions and 2 leaflets. These sessions were based on the education on proper waste management highlight on the proper use of right trash bin with the right waste post-sales area management and the use of microorganisms for the production of bio-fertilizers and bio-fermented solution from biodegradable waste in the market community. Moreover the monitoring communities were done for the proper use of trash bin in the community and providing the right waste management. It could bring the benefits to the community at the initial level especially the realization and attitudes in the suitable waste management since approximated 10% shops keep their shops and area nearby clean thus adding a panoramic view with a good image to the Thewarat market.

The purposes of this study were to investigate the heat transfer and the vibration characteristics caused by front and back vented brake disc which had physically different shapes affecting braking distance. In accordance with the theory of heat transfer the heat transfer rates of two types of brake disc were different and played an important role in the deformation during usage. The single dynamometer was conducted to the experimental work as an engineering tool with boundary conditions according to JASO C406 standard. One degree of freedom (DOF) acceleration signals on the brake caliper were analyzed. The results obviously discovered that the back vented brake disc was able to reduce the vibration up to 43.5% comparing to the front vented brake disc in case of the braking temperature 200C initial breaking speed 50 km/h and the hydraulic pressure of 4 MPa. Besides the hydraulic pressure at 4 MPa generated the maximum vibration. Furthermore the initial braking speed and the braking temperature were also the important factors. Regarding braking distance results the results of the experimental work obviously discovered that the back vented brake disc created braking distance shorter than front vented brake disc. Besides there were important factors as braking temperature hydraulic pressure and initial speed of braking. Especially the high braking temperature caused an increase of deceleration and a decrease of braking distance. Moreover the high hydraulic pressure produced a deduction of braking distance and an increase of deceleration. Finally the initial speed of braking directly varied to the braking distance
