The main objective of this research is to study the factors that affect the work efficiency of personnel. Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon This will lead to suggestions for the development of personnel to be more efficient in their operations. 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 purpose of this research was to explore the organizational commitment and compare factors affecting the organizational commitment as well as study the relationship of the factors affecting the organizational commitment of Rajamangala University of Technology Phra Nakhon personnel. 303 samples were asked to respond to a questionnaire which was used as a research tool. Statistics used for the data analysis were percentage mean One-Way ANOVA and significance level at 0.05. The results of this research revealed that the overall personnel of Rajamangala University of Technology Phranakhon were organizationally committed in good level as well as their work life quality. In addition the level of organizational commitment of the personnel with dissimilarities in terms of the age marital status educational level work experience were 0.05 statistically different. In addition to that the overall job characteristics were positively correlated with overall organizational commitment and work experience. In the Operate overall this was positively associated with the overall organizational commitment.

This research study about rainfall pattern in Thailand due to the influenced of the tropical cyclone. The annual rainfall analysis was derived from the Thai Meteorological Department (TMD) since 1 9 7 1 -2 0 0 0. The analysis of annual rainfall used composite analysis and classification of rainfall patterns with cluster analysis. To measuring the similarity between the rainfall patterns in each year by hierarchical clustering method. In addition use to Single Linkage rules for grouping the rainfall pattern and using the distance between the units close together as possible into consideration. The summarized of rainfall pattern due to the influenced of the tropical cyclone are usually found in the eastern and northeastern regions of Thailand. It is found that a heavy rainfall. The rainfall pattern in the western regions of Thailand has the least amount of rainfall as a result of drought.

Nowadays increasing water pollution has put significant pressure on water resources. Natural organic matter and organic micro-pollutants have been found in potentially harmful concentrations in numerous water sources. Phthalate plasticizers are also micro-pollutants of concern; Di- (2-Ethylhexyl) phthalate (DEHP) is one of the most frequently observed plasticizers in the environment as well as one of the most persistent. The maximum permissible levels of these compounds in drinking water and wastewater discharged to the environment are set at low concentrations. In this research water samples were collected from the New Bang Kaen Canal in Bangkok Thailand (13°4906.1N 100°3042.4E) which receives wastewater from human activities and contains impurities in the water. Several common treatment technologies currently used to remove inorganic and organic contaminants from natural water supplies address serious environmental problems. Properly selected microfiltration membrane processes are elements of effective systems for water purification. Polymeric membranes are of primary interest for membrane separation techniques because they are both practical and effective. However pretreatment before using a microfiltration membrane is necessary for suspended solids reduction. This research used two types of polymeric membranes namely cellulose acetate membrane (CA) and polyvinylidene difluoride membrane (PVDF) and covers the most applicable requirements regarding pretreatment of the water intake. The performance of polymeric membranes for water treatment was also investigated. The water quality of the New Bang Kaen Canal was assessed in terms of turbidity SS and COD. This research has the potential to contribute to the monitoring of water quality in the New Bang Kaen Canal. Water quality monitoring is a fundamental tool for water resources management. The performance of polymeric microfiltration membranes was effective for water and wastewater purification in terms of solids organic substances and micro-pollutant i.e. DEHP compounds. Nevertheless the further development of polymeric membranes regarding fouling on the membrane surface and within pores needs to be improved to increase membrane performance and ameliorate the limitations of microfiltration polymeric membranes.

This research aims to research develop and develop a web-based tourism management application in Kanchanaburi province. An Analysis of Opinion Assessment on Educational and Web Application Development for Kanchanaburi Tourism Route Management.
