This independent study to the teamwork performance that affects the efficiency of government teachers and education personnel affiliated with the schools under the office of the primary education in Bangkok area. The objectives are 1) to study personal factors of education personnel that affect teamwork performance that affect the efficiency of government teachers and education personnel affiliated with schools under the office of the primary education in Bangkok area. Furthermore 2) to study the team composition that affects the work performance of teachers and education personnel affiliated to schools under the office of the primary education in Bangkok area. By using questionnaires designed to teachers and education personnel from the office of the primary education in Bangkok area for 334 samplings using the Taro Yamanae formula. Testing was done in descriptive statistics using frequency percentage mean and standard deviation while hypothesis testing was t-test F-test (ANOVA) and double test by method Least Significant Difference (LSD) and Pearson Product Moment Correlation Coefficient. The result of the study found that most responders were female aged between 21-30 years old working in middle-sized schools and having a bachelors degree. Most had an income between 15001-20000 Baht and most of them had been government teachers in operating positions for 5-10 years as civil servant and the study found team composition factors such as environment composition and appearance the feature design and process affected the teams performance at a high level. The reason was trust between education personnel team members. There also was a high degree of satisfaction with the working environment and the excellent collaboration between team members. Team members were able to resolve obstacles together effectively. There was good communication between members and the members had no conflict with each other’s. However the education personnel should have a positive attitude to work with other people and alone. Negative thinking cause no bias towards others and decrease performance. The results of the hypothesis testing indicated that sex age school size income position level different occupations of government teachers and education personnel could not differently affect teamwork performance as could not different for education job titles and working ages the difference will affect performance of the team composition factors. The factors were statistically significant at the 0.05 level and the team composition factor. There also was a correlation in the same direction with the efficiency of teamwork of government teachers and education personnel. It was statistically significant at the 0.05 level.

This research aims to study the level of fundamental factors in the composition of teamwork the training and team system performance factors of Thai go chess sports and the factors affecting the efficiency of teamwork of Thai go chess. It was a quantitative method doing a survey research. The sample group consisted of 286 members from the Thai go chess Association of Thailand. The research study tool was a questionnaire. The statistics used were frequency percentage mean standard deviation and Multiple Regression Analysis. The result of the study showed that 1) factors in the composition of teamwork are like team leader team member and teamwork were at the highest level. 2) Training factors including planning implementation and evaluation were very high and the issue at the highes level was the assessment of necessity. 3) The efficiency of the teamwork of Thai go chess highly depends on creativity and continuous improvement at the highest level and high-level issues are communication cooperation and coordination. 4) The essential factors in the composition of teamwork affecting efficiency teamwork of Thai go chess including team members and operating systems are at a statistically significant level of 0.01 5) Training factors that significantly affect the efficiency of teamwork of Thai go chess include assessment planning operation and evaluation at a statistically significant level of 0.01

The purpose of the research is to devise and implement for testing the ability to absorb energy from vibration. The results are obtained from simulating the operating status of small machines. In order to get the mechanical force from the vibrating of the machine by using piezoelectric materials (PZT) It was found that the size of the piezoelectric materials used in each condition affected the energy absorption. There are variables interested in different diameters at 27 and 35 millimeters. The result shows that the dielectric displacement is directly proportional to the force used but is inversely proportional to the size of the cross-sectional area of the piezoelectric material. In addition the ability to absorb energy in one second is 4.51 volts and has a maximum energy of 7.4 x10 -8joules.

This study purpose was to investigate the changes affecting the working behavior of non-profit organization personnel. The population used in this study was 64106 non-profit organization personnel: Foundations and associations. The data was collected using a questionnaire from 203 non-profit organization personnel. Statistical multiple regression analysis was used to test the study hypothesis. The study results revealed that there is a correlation between organizational changes including the attitude change change in corporate culture technology change and changes in organizational structure and the working behavior of the personnel of the non-profit organization as a whole including the aspect of helping others consideration for others patience sense of duty and cooperation with the statistical significance at 0.01 level.

Ground grid design of substation is very important. It will help prevent the danger caused by the fault which causes the high step voltage and high touch voltage and may cause the operator to die. It also helps prevent damage to equipment and increases reliability for power systems as well. Currently the Gas Insulated Substation (GIS) has been built a lot especially in areas with limited space because it takes less space than the Air Insulated Substation (AIS). In order to create a substation of the GIS model instead of the AIS model. In order to create the GIS instead of AIS including the improvement or maintenance of the substation it is necessary to build another small substation to supply electricity to replace electricity from the original substation. However there are two substation stations in the same area may cause an increase of high-slope ground potential between the ground grid systems of both substations. It will cause high step voltage and high touch voltage while the fault is diminished. Therefore before improvement or maintenance of substation the ground grid distance and the size of the newly constructed substation must be analyzed that what effect on step voltage and touch voltage generation. Including studying the effects of step voltage and touch voltage that will occur.
