This research was aimed to 1) study the influence of transformational leadership and 2) to investigate the communication styles towards teamwork of academic employees at Aksorn Charoenthat Company Limited. This is descriptive research collecting data through a questionnaire constructed from reviewing relevant documents. 142 Aksorn Charoenthat Company Limited employees responded to the five-scale questionnaire divided into 4 parts with the total of 52 items. The collected data were statistically analyzed by percentage mean (μ) standard deviation (σ 2) multiple regression analysis to test multiple linear regression and Pearson Correlation Coefficients. The results of the hypothesis test on the influence of transformational leadership and communication styles towards teamwork of academic employees at Aksorn Charoenthat Company Limited showed that (1) the correlation coefficient analysis between the leadership and the teamwork were positively related and statistically significant at .01 level; (2) the correlation coefficient analysis between the communication styles with the teamwork of Aksorn Charoenthat Company Limited employees was positively and statistically significant at .01; and (3) the transformational leadership and communication styles influenced the teamwork of Aksorn Charoenthat Company Limited employees statistically significant at .05 (R = .724) and (R = .668).

The purposes of the study were to investigate transformational leadership and learning organization of bureaucratic official and personnel of Office of the Private Education Commission. The samples were drawn from 169 bureaucratic officials and personnel of Office of the Private Education Commission by Taro Yamane formula sampling. The five-scaled rating questionnaire had obtained the reliability coefficient at 0.95. The collected data were analyzed by the percentage distribution mean and standard deviation; and t-test f-test and Pearson product moment correlation coefficient. The results were as follows. 1. Transformational leadership of the executives from the Office of the Private Education Commission was seen high in general. When considering in each aspect it was found that the samples could highly perceive the executives’ transformational leadership in every aspect ranging from inspiration motivation idealized influence of charisma leadership individualized consideration and intellectual stimulation respectively. 2. Learning Organization of the bureaucratic officials and personnel of Office of the Private Education Commission was high ranging from Mental Model Team Learning Personal Mastery System Thinking and Shared Vision respectively. 3. Transformational leadership and Learning Organization of the bureaucratic officials and personnel of Office of the Private Education Commission were positively related at 0.05 statistical significance and the reliability coefficient at 0.595 which demonstrated the positive relationship averagely.

This research work was to study the effect of moisture on mechanical properties of wood/polyvinylchloride composites (WPVC). WPVC specimens in ratio of PVC and wood (100:100 by weight) were prepared by using twin screw extruder. The water conditions for WPVC specimen immersion testing were varied for temperatures of 30-70 oC and specimen immersion time of 0-120 h. The moisture effect was investigated by measuring flexural properties and hardness of WPVC as comparing with case of PVC specimen. The result suggested that flexural modulus of WPVC tended to decrease with increasing time of water immersion and then remained unchanged at immersion time of more than 72 and 48 h for water temperature of 30 and 70 oC respectively. The decrease rate in flexural modulus enhanced when water temperature increased. Flexural modulus of PVC slightly changed with increasing both immersion time and water temperature. Flexural strength for both PVC and WPVC specimens were found the change at water temperature of 70 oC only. Flexural strength of PVC tended to slightly increase with increasing immersion time whereas flexural strength of WPVC slightly decreased with increasing immersion time. Hardness of PVC specimen in cases of both water temperature of 30 and 70 oC slightly increased with increasing immersion time. For WPVC hardness tended to decrease with increasing immersion time and water temperature.

The objective of this research were (1) To study the Influence of supervisor’s transformation leadership on job satisfaction; (2) To study the Influence of supervisor’s transformation leadership and job satisfaction on organizational commitment; (3) To study The Influence of transformation leadership job satisfaction and organizational commitment on employee’s job performance (4) To validate a causal relationship model of influence of supervisor’s transformation leadership on job satisfaction organizational commitment and employee’s job performance of Tisco Bank Public Company Limited. The variables in this investigation consisted of the following; supervisor’s transformation leadership as the independent variable; and job satisfaction on organizational commitment as mediating variables and employee’s job performance as dependent variable. The researcher used quantitative methods which involved empirical research. The instrument of research was a questionnaire used to collect data form 345 personnel of Tisco Bank Public Company Limited. The statistics used in data analysis were frequency mean percentage and structural equation model analysis. It was found that the model was consistent with the empirical data. Goodnessof fit measures were found to be Chi-square (2) = 198.935; Degree of freedom = 169; p–value = 0.057; Relative Chi-square (2/ df) = 1.177; Goodness of Fit Index (GFI) = 0.950; Adjusted Goodness of Fit Index ( AGFI) = 0.925; Comparative Fit Index (CFI) = 0.997; Standardized Root Mean Square Residual (SRMR) = 0.039; and root Mean Square Error of Approximation (RMSEA) = 0.023. It was also found that (1) supervisor’s transformation leadership had a positive direct effect on job satisfaction; (2) supervisor’s transformation leadership had a positive direct effect on organizational commitment; (3) job satisfaction had a positive direct effect on organizational commitment; (4) organizational commitment had a positive direct effect on employee’s job performance; and (5) supervisor’s transformation leadership had a positive direct effect on employee’s job performance. On the basis these findings the researcher recommends that Tisco Bank Public Company Limited more fully focus on transformation leadership to deepen job satisfaction and organizational commitment and employee’s job performance.

The purpose of this research is to study Development of Computer ted I nstruction Subject Change Management and to find out efficiencies Satisfac on towards the package. The research tools were : 1) Development of Computer Assisted Instruction Subject Change Management 2) Achievement tests 3) Quality a sessment and evaluation form for multimedia software and 4) Questionnalre of leamers satisfaction Sampling groups composed of 62 Bachelor degree (4 years) Faculty of Business Administration Rajamangala Unniversity of Technology Phra Nakhon Researchresulty revealed that the effciency of the Computer Instruction Package was at E1 / E2 = 81.65/82.39 corresponding with 80/80 creteria.
