Data was collected between October 2018 and September 2019 which was a survey research using a questionnaire consisting of 4 parts: 1) general information of the respondents which was demographic characteristics 2) Satisfied with the operational efficiency 3) quality of working life and 4) Other suggestions with a sample of the research as Personnel under the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon amount 50 people. Data analysis used descriptive statistics for demographic data. And use statistical methods for analysis of relevant factors and testing hypotheses. The results of the study showed that the factors of work success of the Faculty of Science and Technology personnel Rajamangala University of Technology Phra Nakhon Able to work according to the set goals Without having a backlog And proud of the work Able to solve immediate problems Which is considered to be very good therefore Faculty of Science and Technology Should focus on personnel development in the workplace In order to further improve the operational efficiency of the personnel.

The objective of this study were 1) to develop the gas detector unit for installation on Drone and 2) to test the operational sensitivity of the developed device. The development steps included designing complying the electrical circuit testing the electrical system and online connecting system. Besides the operational sensitivity of the developed device was tested comparing the Gas Alert Micro 5 IR the reference gas detector device both in the laboratory and the field site. The results showed that the developed gas detector could detect carbon dioxide carbon monoxide and methane and displayed the results via Line notification every minute. Additionally carbon dioxide detection by MG-811 sensor gave the results similar to the reference device by 95 percent of significant level with the average amount of detected carbon dioxide in the laboratory and the field site were 700-915 ppm and 138-399 ppm respectively. However the measured results of carbon monoxide and methane from the develop device were relatively different to the reference device. Further study on carbon monoxide sensor and methane sensor calibration are recommended.

This research was to develop the handbook for training conference seminar and study trip of the faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The samples were 100 officers the faculty of Home Economics Technology. Data collection were from study the regulations of the Ministry of Finance and the regulation of Rajamangala University of Technology Phra Nakhon the interview and questionnaires of the appropriateness of the handbook. Descriptive statistics that are frequency percentage mean and standard deviation was used for data analysis. The result of this study found that: 1. The way of the handbook development for personnel operation in which training conference seminar and study trip of the faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon that should accelerate were the development operation handbook of the process and procedure of the participation conference seminar and study trip both participate inside and outside the department and connect with the human resource management of the university. 2. The result of the appropriateness of the handbook for the participation conference seminar and study trip was appropriateness. The user satisfied the handbook in the high level (𝑥= = 4.13 S.D. = .694) and followed with 4 categories that are the accuracy the appropriateness the possibility and the usefulness in the high level.

The purpose of this descriptive study is to behaviors perceived communication effectiveness and the relationship between communication behaviors and perceived intra-organizational communication effectiveness using 70 sets of closed-end questionnaires as a tool for data collection from employees at a selected independent organization. Statistical methods for data analysis included percentage mean( μ ) standard deviation( σ) and correlation coefficient. The results of the study indicate that most of the survey respondents ae male aged 51 years and older with a marital status. The education level is bachelor’s degree. In respect of information perception intra-organization matters are the main priority among employees with a focus on the information within the organizational unit they belong to or benefits related to them.
