The objective of this study aims to develop a concrete boat by using lightweight concrete. The use of granular foam replaced the aggregate in various quantities to reduce the weight of boat. The replacement ratios of aggregate by the granular foam were 0 25 50 75 and 100% by volume of aggregate. The test results of compressive strength tensile strength modulus of rupture and unit weight of concrete were used to find out the appropriate mixture for producing the concrete boat. The results indicated that the appropriate mixture for producing concrete boat was the replacement of aggregate by granular foam at 100% which had the compressive strength at 28 days of 50.59 kg/cm2 and the unit weight was 949.71 kg/m3. The weight of lightweight concrete was lighter than the normal concrete about 57%. The prototype of lightweight concrete boat which had 1.04 m wide 2.20 m long and 0.38 m height had about 50 kg of weight. The maximum weight capacity of the boat was 240 kg. The cost of a lightweight concrete boat was about 650 baht

The objectives of this research are to study the operation model for highland development of the Royal Project the model of knowledge extension to the farmers the result of operation to the farmers by the Royal Project and studying of the effective factor of the Royal Project development. This research is use the quantitative by collecting the data by interviewing. The result of the research there are 7 important models of development by the Royal Project to the farmer on the highland; (1) the operation procedures (2) operation plan (3) Format of operations (4) Officers in the center and in the area (5) Values and corporate culture (6) The farmer in the area and (7) Potential of the area. For the knowledge extension to the farmers the advice/visiting to the farmers is in top level. The “support/facilitation to the farmers” there are a purchasing the goods and agricultural products and product quality development in very high level. And the result of operations the Royal Project to the farmers resulting in economy the higher income and increasing the asset in high level the liabilities decreased moderately. In the social the farmers are developing at the high level in every topic. It is shown that the resulting in operation of the Royal Project can help in social development. And in the environmental there is an increasing of a conservation of the upstream area in very high level. The factors that effect to the result of operation by the Royal Project in economy social and environmental are depended on the model of operation support/facilitation and the quality of the officers in the Royal Project.

The purposes of this research were to (1) study the needs of teachers and students in Secondary Education Service Area Office 11 in English instruction using mobile electronic devices (m-Learning) and (2) to develop the model of English language instruction using mobile electronic devices (m-Learning) for Upper Secondary Students in Secondary Educational Service Area Office 11. The samples were 222 teachers and 394 students taken from Secondary Educational Service Area Office 11 using a Taro Yamane’s formula with the significant level of .05. The research procedure was divided into two phases. Phase one was the study of the needs of teachers and students in teaching and learning using mobile electronic devices two sets of questionnaires; one set for teachers and one set for students were used to collect data. A model of English instruction using mobile electronic devices was created in this phase. Phase two was the verification of the developed model by the experts. A verification form was used to collect data. Data were analyzed through mean and standard deviation. The research findings were as follows:

This research aimed to utilize by-products from small- scale and medium-scale Industries to produce 3 products. The first was formulate pasteurized milk juice beverages (PMJB) consisted of 10%reprocessed milk 45%pineapple juice 45%lychee juice 0.55%HM pectin and 1%sugar. Pasteurization at 72C 15 s kept at 6?1C 8 days. PMJB has 2.8%protein 2.1%fat 8.8%carbohydrate 0.021%Ca and 65.3 Kcal. The second product was cracker added ?-carotene from carrot. The chemical specification was 3.15% moisture 5.03% protein 8.07% fat 65.12% carbohydrate 5.42% ash and 3.15% fibre. The Third product was accessories which use from sisal rope

The purposes of this research were to make artificial wild orchids from joint-vetch to imitate the natural one. Researchers studied joint-vetch dyeing Thai wild orchids forming from joint-vetch Thai wild orchids selecting by considering appropriate appearance shape and composition and five experts gave the opinions on the chosen researched orchids. The development of wild orchid product from joint-vetch was transferred to housewife’s group in Phra Nakhon Si Ayutthaya province. The satisfaction of the research product was investigated from 60 target groups. The overall satisfaction of the participants after attending the training course was at the high level (4.73). Other aspects were found that the average mean (4.74) of the facility was at the highest level. The average mean (4.73) of the knowledge application was at the highest level. The average mean (4.71) of the product was at the highest level. The average mean (4.68) of the instructor was at the highest level. The average mean (4.35) of the understanding was at the high level.
