The study was aimed to 1) investigate influence of supervisors’ behavior leadership affecting working motivation of ground operation employees and organizational effective of a low cost airline and 2) study influence of supervisors’ behavior leadership on organizational effectiveness of a low cost airline. This research is descriptive collecting data through a questionnaire constructed from reviewing relevant documents. 88 samples responded to the five-scale the demographic questionnaire divided into 4 parts with the total of 84 items. The collected data were statistically analyzed by percentage mean ( X?) standard deviation (S.D.) multiple regression analysis multiple linear regression and Pearson Correlation Coefficients (Pearson Correlation Coefficients) The results showed that the hypothesis test on the influence of supervisors’ behavior leadership affecting working motivation of ground operation employees and organizational effective of a low cost airline yielding (1) the correlation coefficients between supervisors’ behavior leadership and employees’ motivation were positively correlated at the .05; (2) he correlation coefficients between supervisors’ behavior leadership and organizational effectiveness were statistically significant; and (3) the supervisors’ behavior leadership affecting employees’ working motivation and organizational effectiveness of a low cost airline at .05 level of significance (R = .712) and (R = .598).

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 on influence of motivational factors towards on organizational loyalty and performance of operational personnel in health science group in an autonomous university were to 1) study the influence of motivational factors on organizational loyalty among operational personnel and 2) to study the influence of motivational factors on the performance of operational personnel. The questionnaire was applied for data collection with the reliability acquired through Alpha Coefficient of 0.982 which was used to tryout with 30 people and collect data from 124 operational staff in health science group in a state-run university located at Chulapat building (source: Office of Personnel of Faculty of Allied Health Sciences Faculty of Nursing Faculty of Nursing and Faculty of Sports Science January 31 2017). This research is a descriptive research. The data obtained from the researchers questionnaire was analyzed by statistical analysis program including percentage analysis is used to analyze the individual factors mean used for interpreting various data and standard deviation to interpret data in various areas and multiple linear regression for testing the hypothesis as well as Pearson correlation. The research revealed that the hypothesis testing on motivational factors towards organizational loyalty and work performance of operational personnel in health science group in an autonomous university included 1 ) work success 2) work progress 3) acceptance 4) responsibilities and 5) job description while supporting factors included 1) salaries 2) advancement opportunities 3) relationships with others 4) status 5) policy and administration 6) work environment 7) work security and safety which influenced on organizational loyalty and performance of operating personnel in health science group at the 0.05 level of significance.

The objectives of this research are to propose an approate and efficient model for analyzing rice corn and sugar yields data. A linear mixed model (LMM) with spatial correlation following the conditional autoregressive model (CAR) was adopted. The results show that for rice yields if the amount of rainfall in a harvest season increases 1 mm the yields will decease by 25.74 tons. if the temperature in the harvest season increases 1 Celsius the yields will decease by 212.60 tons and according to the trend the yield will increase by 15.80 tons each year. For sugar cane yields if the amount of rainfall in the harvest season increases 1 mm the yields will decease by 51.35 tons. if the temperature in the harvest season increase 1 Celsius the yields will incease by 121.30 tons and according to the trend the yield will increase by 29.93.80 tons each year. For corn yield if the amount of rainfall in the havest season increases 1 mm the yields will incease by 73.45 tons. if the temperature in he havest season increases 1 celsius the yields will decease by 40.44 tons and according to the trend the yield will increase by 1.74 tons each year.

This study was carried out to evaluate the influence of pruning on floral emergence fruiting yield and fruit quality in longan. Fifteen years old “Daw” longan trees were pruned in June 2013 at Agricultural Technology Research Institute Rajamangala University of Technology Lanna Lampang province. The longan pruning for removing some branches consisted of 4 treatments i.e. 25 50 and 75 % compared with no pruning. The result revealed that there was no effect of treatment on floral emergence or leaf flushing after potassium chlorate application. However the 25-75 % pruning gave greater new shoot length leaf width and leaf greenness than that of no pruning. The pruning treatments increased fruit size while the highest pruning (75 %) decreased yield and the no pruning produced the lowest yield.
