The study was aimed at 1) studying the operation of the professional group in the Bang Sa Community in Amphor Laem Singh Chanthaburi Province and 2) studying the factors that strengthen the professional development in the community. 3) guidelines that promote the strengthening of professional development for the community. The study applied the combination of the quantitative and qualitative research methods. The sampling subjects were the villagers who weave mats from kok plant or reed mats as their supplementary profession. They had not received any constructive professional development. The quantitative data collected were computerized into percentage means and standard deviation. The qualitative data were analyzed for content and subject matter. It was found that 1) the operation was done by the group of housewives who actively participated consulting among each other and dividing the roles and responsibilities such as planting reed cutting reed dyeing the raw material with organic substances designing new patterns on reed fiber and transforming the products. The operation was done based on the folk knowledge that had been passed from generation to generation without using modern technologies. 2) The factors that strengthen the professional development for the community are 2.1) the non-interest loan; 2.2) the experts who can help in designing a variety of fashionable products; 2.3) the sale distribution to distributors & shops or through the website; 2.4) the design of modern patterns that attracts consumers; 2.5) the advertising by the government in many platforms such as TV ads radio ads print ads in newspapers and magazines and product trade exhibition (expo) or festivals like Muang Thong Thani Expo. 3. Guidelines to promote the strengthening of professional development for the community are as follows 3.1 Establishment of community enterprises. Membership Registration To make money together 3.2 Processing of new products that meet the standards Group to produce standard products to meet the needs of the market. To create products or new products. The uniqueness of Laem Sing district. Chantaburi province To enhance produce quality and certifies quality standards for products 3.3 A professional group of reserves 3.4 The amount of capital required to bring a group of professional procurement of materials to members of woven reed mats as its reserve (stock). To support the distribution and resolve shortages 3.5 The need to develop new and advanced packaging to optimize the value of its products 3.6 The study promotion and sponsorship and development group to Develop products to meet customer needs. Channel Marketing and increased sales of the bands career woven reed mats. Laem Sing Chantaburi province.To encourage the development for sustainability. Raise the working group members to understand 3.7 Preparation of accounting systems in a systematic way. Which requires the Commission and members of the profession can be understood together. That can detect clear

The tungsten carbide powder which recycled from the scarps of cemented tungsten carbide produces the purity of 99%. Using this tungsten carbide powder to manufacture a cutting tool and test its properties are the main objective of this work. Based on the standard SNMG 120408 the cutting tool with the dimension of 12.7x12.7x4.76 is fabricated. With the 100 hours of Ball milling grinding Cobalt mixing and sintering at 1430 °C the experimental result is impressive. At 15% of mixedcobalt the cutting tool with the hardness of 2031.6 HV be able to cut S45C steel in the feed rate of 0.2 meters per revolution and 45 m/min in the cutting speed. Besides that it provides the depth of cut of 0.25 mm and when it reaches the cutting distance of 4200 mm the surface roughness is 3.65 μm. In comparison with the cutting tool made of imported tungsten carbide powder which has a hardness of 1254 HV it turned out that our cutting tool has the equivalent quality in terms of hardness and wear resistance. Hence this work is considered to be a material development and a tungsten carbide cutting tool manufacture those would be the vital base to lead us to a commercial production.

This study developed the cemented tungsten carbide by steadily sintering at 1430 °C for one hour. The tungsten carbide structure is a long shape. Its grain size has a difference between width and length and there are high distribution of sizes and shapes. In comparison with the work piece which has the similar size of grain structure the milling duration of tungsten carbide is less even though the condition of WC-Co is the same (95% WC – 5% Co). When the sintering of 1400 °C with the identical milling duration is performed. It turned out that both grain structures of the tungsten carbide and the work piece are similar and their grain sizes are slightly different. However when the grain structures are almost the same and sphericity is increased the hardness and wear resistance will also be improved. Therefore the size of grain structure between 1.00 – 3.00 μm with the milling duration of 100 hours will provide a work piece that has a wear resistance according to international standard

The objectives of this research are to study the basic recipe of Sane Jan to study the appropriate proportion of pumpkin flour in Sane Jan to study the acceptance of pumpkin four supplemented Sane Jan and to study the amount of Vitamin A in pumpkin four supplemented Sane Jan from the basic recipe by Randomized Completely Block Design (RCBD) and to evaluate the sensory quality of appearance color smell texture and overall liking with 40 testers by tasting of the 9 – point hedonic scale. It was found that the second recipe there are the ingredients of glutinous rice flour 75 grams rice flour 150 grams yolk 100 grams cream 960 grams sugar 500 grams coconut sugar 10 grams and Sandalwood powder 0.5 grams is the highest accepted. Then study the appropriate proportion of 3 pumpkin flour levels which are 50 percent 60 percent and 70 percent. It was found that the amount of pumpkin flour at 60% has the highest average. To study on consumer acceptance of pumpkin flour supplemented Sane Jan 60 percent. It was found that consumers were accepted in excellent level accounted for 75 percent. To study about configuration of chemical found that Sane Jan basic recipe does not have vitamin A and pumpkin flour supplemented Sane Jan has vitamin A for 20.12 percent. It has the difference for 20.12 micrograms. In the basic recipe does not have any yellow color and the pumpkin flour supplemented Sane Jan has color for 1.0 milligrams.
