The purposes of this research were to study personal information work motivation organization commitment compared according to demographic characteristics and influence of work motivation towards organization commitment of Y generation employees working for domestic high-speed service providers. 160 Y generation employees working for domestic high-speed service providers were the samples. The questionnaire were distributed on-line and analyzed by descriptive statistics including the frequency percentage mean and standard deviation t-test F-test One-way ANOVA Persons Product Moment Correlation Coefficient and multiple regressions. The results revealed that the employees’ who were different in terms of marital status and work tenure had different organization commitment. The employees with different gender age education and income did not differ in terms of their organizational commitment. In the overall the level of corporate commitment was very high; the relationship between motivation and organizational commitment positively correlated and had the influence on Y generation employees’ organizational commitment at the 0.05 level of significance.

The purposes of this research were to investigate the perception on activity maneuver and supporting factors regarding employees participation in Corporate Social Responsibility (CSR). The sample consisted of 250 employees of Prachin Buri Industrial Estate 304 Prachin Buri Province. The research results are as follows. The employees’ perception on activity maneuver information in CSR in the overall was at the highest level (= 4.62 S.D. = 0.44). The overall perception on the information had a statistically significant positive relationship with employees’ participation at the .01 level (r = .347). When considering each aspect the perception on activity information positively correlated with participation in CSR activities at the .01 level of significance (r = .295). The results of the appropriate model analysis used to forecast the employees’ perception on CSR activity indicated that the perception of policy information had a p-value of .012 meaning that the policy factor could predict the employees’ information perception at 0.05 statistical significance with a tolerance of .704 the VIF was 1.420. As for the planning aspect the tolerance value was .617 with the VIF value of 1.621 and the activity guideline aspect had its tolerance value of .532 with the VIF value of 1.881. This means that the perception regarding policy planning and guideline aspects was not beyond the Multicollinearity variables because their tolerance values were not lower than .2 and VIF did not exceed 10. Also the results of the regression coefficient analysis of factors affecting the information perception on CSR activities in the form of raw scores (B) were .298 .168 and .209 indicating that the variables predicting the perceived social responsibility included policy (X1) planning (X2) and activity guidelines (X3) and the three variables can together predict the level of awareness of CSR activities. These three factors could jointly predict the information perception on CRS at 11 percent. Factors promoting the employee participation on social responsibility were generally at a moderate level ( = 2.94 S.D. = 1.22) and there was a statistically significant positive correlation with employee participation at the .01 level (r = .855). When looking at each aspect it was found that factors promoting the employee participation in training and activities were positively related to the social responsibility aspect statistically significant at .01 (r = .773) and (r = .841). The results of the analysis of the appropriate models used to predict the factors contributing to employee participation showed that employees’ activity and training participation had the positive influence on CSR activities with p-value of .000 and .001 which was less than 0.05 indicating that their attendance could predict promoting factors of the employee participation statistically significant at the .05 level. This means activity and training participation factors could contribute to the promotion of employee participation statistically significant at the .05 level. While the training had a tolerance value of .225 the VIF value of 4.450 the activity participation had a tolerance value of .259 the VIF value of 3.858. As for being a group member the tolerance ship was .193 with the VIF value of 5.185 showing that participating in training and membership did not go beyond the Multicollinearity due to the tolerance value of not less than 2 and VIF value of not more than 10. The result of the regression coefficient analysis of factors affecting the level of factors contributing to employee participation on CSR operations were .157 .391 and .028 showing that the predicting variables of the employee participation promotion were training (X4) and participation (X5) and group membership (X6). The three variables could predict the level of factors contributing to employees participation on CRS at 72.70%

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 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.
