The purpose of research is to study the carbon footprint evaluation of products for thread turned Tungsten Carbide 16ER60 of production. To assess amount of greenhouse gas emissions that affect the environment. The key component in the calculation include raw material production material energy and waste January 2018 and March 2019. The scope of the study is the assessment of Business-to-Business (B2B). From the assessment of the carbon footprint it was total of greenhouse gas was about 1.1559 Kg CO2e which was divided from raw material about 0.0118 Kg CO2e and production process about 1.1441 Kg CO2e. From the improvement reducing electricity of sintering furnaces machine and lighting system was reduce greenhouse gas emissions about 0.3249 Kg CO2e or decrease percent 71.88 CT

The public relations channels via Facebook and agency website. The short courses of the Faculty of Mass Communication Technology consisted of 14 courses including 1) shooting and editing video with mobile phone for online sales 2) photography for storytelling on mobile phone 3) online marketing 4) graphic design for brand communication 5) Website development for community brand communication 6) photo retouching techniques 7) making sales with smartphones 8) offline marketing campaign 9) online selling via social network 10) application for online teaching 11) video and audio editing 12) creating Thai wisdom for community products 13) speaking and communication in the community 14) packaging design for community products.

The objective of this research is to study the suitable factor level for the improvement of annealing furnace for rolled coils steel sheet. The experimenting has been performed to find suitable oxygen level by 5 annealing furnace experiment. The research has been started by collection the combustion. After that the burning adjustment by changing combustion technology with 5 levels of BGCV control valve open as 23% 40% 50% 75% and 100% has been implemented. The combustion adjustment data are recorded analyzed and compared with incomplete combustion value. The research result has been found that after improvement the combustion value. The percentage of oxygen level are improved to the better quality which standard at MV0-49% equal 2.5-4 O2% and MV50-100% equal 1.5-2.5 O2% conclusion 1 furnace as follows at the MV23.1% MV40% MV50% MV75% and MV100% level of oxygen as 2.5% 3% 3% 2% 1.5% and level of carbon monoxide as 0 ppm 2 ppm 2 ppm 2 ppm and 0 ppm respectively. Resulting of fuel energy consumption in the annealing process has been reduced around 225608 baht /year/furnace. Therefore it can depict that energy saving and annealing furnace efficiency improving are increased. The modified parameters will be applied to be the new standard reference values for the further engineer’s operational manual.

Using copper wire instead of gold wire can reduce a lot of cost in IC production of semiconductor industrial. However the circuit stability (Circuit Reliability) is less than the use of goal wire. Therefore the study to improve the production of integrated circuits in the part of the wire bonding process by increasing the baking process. It is an important process to improve the quality of the integrated circuit between Cu wire and chip. For this experimental study of baking process it was performed by comparing IMC values at 175 ˚C and 200 ˚C. The quality of workpiece was tested and measured by Scanning Electron Microscope (SEM) machine every 30 minutes. The research experiment found that the temperature with effect to the workpiece quality to stabilize the IMC value was 175 ˚C for 9 hours nevertheless the new temperature at 200 ˚C it has been applied with only 3 hours. Finally the IMC testing result is higher than the average of the at 60% standard acceptable level as other research reviews and it also higher than the acceptable level of the industry level at 80%. Hence this result can reduce time cost of IC and workpieces production and it also including the higher quality of the products.

The purpose of this research was to study level of the preliminary cost calculate for a large building in Roi Et province and to study the factors that affected on initial cost reduction of large building constructions in Roi Et province. The sample group used in this research were devisers supervisors project managers and construction contractors in Roi Et province. There were 5 projects with a total of 145 people. The instruments used in the research were a 5 level rating estimation questionnaire. Data were analyzed by using frequency percentage mean standard deviation and the hypothesis tested by using Multiple Linear Regression with (Enter Regression). The result of the research shows that An analysis of opinion on principal control of large building constructions in Roi Et province. It was found that the practice level was at the highest level. Which is arranged in order from the highest average to the lowest namely machinery cost material cost contractor cost operating cost and labor costs respectively. and The analysis of Regression Model Development for Preliminary Calculate Cost of construction works had resulted in lowering the initial cost of large building constructions in Roi Et Province of 5 factors included structural design architectural design interior design system design and exterior design. Resulting in reducing the initial cost of large building constructions in Roi Et province with statistical significance at the level of .01 level.
