The purpose of this research is to study the Labor Productivity Rating of workers and the quality of work that has been done by studying dry process bored pile which is 0.50 x 24.00 meters in diameter 170 piles at the construction of a building in Bangkok. Researchers conducted a cycle closed system of dry process bored pile into the four activities are: (1) the movement of the drill into the bored pile position (2) the casing procedure (3) the reinforcement procedure and (4) the pouring of the concrete and casing removal. The results showed that yield of dry process bored pile have an averaged Labor Productivity Rating about 275.31 minutes/pile The Quality jf the research has been divided into two cases: (1) quality of bored pile by testing the integrity of the pile by the Seismic Integrity Testing method in the standards of ASTM o 5882-00 found that 95.30 percent of the piles were in perfect condition and a slightly defective of 4.70 percent and (2) the position of bored pile found to be in accordance with allowable error of 100 percent. The results of the study can be utilized in work planning estimating cost of Labor and monitoring and tracking the progress of the work.

The objectives of this research were to select the most appropriate forecasting model for uncertain demand of hot-rolled steel and to find the purchase amount and the reorder point of some raw materials in order to minimize the total cost of production in an iron and steel production planning. The three forecasting models which were exponential model ARIMS model and the proposed Bayesian model were studied. An iron and steel factory in Samutprakarn province was a prototype for this study. Because of their uncertain high demand the Steel H-Beam Steel plate steel round bar and black steel round bar with various sizes were selected and their parameters including demand rate inventory cost back order cost and setup cost were collected. The study found that the proposed Bayesian forecasting model is the most appropriate. The predicted demand and all parameter values were used to find the purchase amounts and the reorder points of the raw materials under the (rQ) policy of the stochastic inventory model.

This research has been object to development weaving machine design weave dye and Hyacinth paper and Instruct technology give community District Bangsai Amphur Province Ayutthaya which get instruct technology 20 persons. Research result to invention make up weaving machine. Fiber from Water Hyacinth dye Yarh Pa Per from water Hyacinth and product about 11 products. Evaluation from the participants were female aged 35-55. They were workers and earned 500-1000 Baht per month. Before training they had little knowledge. The training contents were correct and up-to-date. The trainers were excellent. The material equipment and documents were the most appropriate. The Participants had good attitude and the designing and developing of water Hyacinth’s was the most appropriate.

The development vetiver grass Product style. The product development were 2 categories Mean office implement 5 patterns and home implement 5 patterns. Engage in prototype product and relay the pattern action training in technology for community groups in Cha-am sub district Cha-am district Petchaburi province. The tolls of research were compost of product prototype The questionnaire and the work evaluation. The result of this research was assessment of vetiver grass products for 10 categories There were female 7 4.5% 31- 40 years old 46% the occupation were government officers 30% bachelors degree 51% and the average income 10001- 15000 baht 41%. The thought of vetiver grass product in the kind of office implement. B4 pattern were the most suitability in the pattern the design the size the decorative the color the advantage usage and the generalization was 4.61 4.704.65 4.59 and 4.60. The thought of vetiver grass product in the kind of home implement. B4 pattern were the most suitability in the pattern the design the size the decorative the color the advantage usage and the generalization was 4.684.604.65 4.70 and 4.71. The training assessment the trainee majority groups was 31 - 40 years old of female the Occupation were farmers and the lower income 5000 baht. Before training they had the knowledge in The development vetiver grass product weave and modify in low level After training they had the opinion assessment about the development vetiver grass product decorative the advantage for themselves and community groups in the excellent level average value was 4.494.38 and 4.42. They required to train in the next time in the excellent level vas 4.73

The purposes of this research were to design and develop bags from Surins silk at Bam kae Yai community Ban Kae Yai Sub - district Surin The research instruments wewe 20 original bags questionnaire and training evaluation from The research findings were concluded as follows : 56 % female aged between 30-40 years. 41 % were government officers. 25.5 % get Bachelors Degree and averge income 10000-15000 bath. Bags type A B and C were appropriate in pattern style colour size total average 4.534.51 and 4.48 The participants were female aged between 30-40 years income below 5000 bath. before training the participants had little knowledge of designing and sewing bags from Surins silk after training they had more knowledge and needed more training
