Weather forecasts are very necessary to predict the future weather conditions. The important thing in forecasting is the model and variables. The model used in the forecasting must be accurate and effective. In addition the variables used in forecasting must be comprehensive and appropriate to be able to represent the forecast. The initial conditions for forecasting must be appropriate and reliable. There are many methods to generate the initial conditions in forecasting. To generate the initial conditions for winter monsoon prediction with Kalman Filtering method which is a method used to predict the status of various systems and able to create values of variables used in forecasting to have a variety of similarities can be used as a starting variable in forecasting very well. In this research the winter monsoon prediction by the Shallow Water Model and validating the initial conditions by Root Mean Square Error (RMSE). The result of weather prediction in the winter monsoon can be used the Kalman Filtering method for generate the initial conditions.

The objective of this research is to study the factors affecting the academic position of faculty members of the faculty of science and technology Rajamangala University of Technology Phra Nakhon which consists of 5 divisions; Division of Environmental Science and Technology Division of Industrial Materials Science Division of Computer Science Division of Science and Division of Mathematics and Statistics. By using SWOT Analysis tools it is found that the main strengths are the progress in the professions increasing of the development of their knowledge potential and fame. The main weakness is the lack of understanding of how to write teaching documents lack of time and lack of interesting research topics. An opportunity is the mandatory criteria of the university. The faculty has financial support for academic positions and other rights from academic positions. The threat is the lack of research budget. The faculty does not have specialized counseling officers and frequently change the assessment criteria. We use the results of the SWOT analysis to group relationships with the TOWS Metrix tool analyzed in the form of a matrix relationship to define different types of strategies to suggest the results of the study in formulating policies to help support and encourage faculty members of the faculty that can further be determined for academic.

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 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.

The objective of this research was to study formulas basic production process and nutrition value and consumer test of frozen Chaya vegetable cream soup. The results indicated that color aroma taste consistency and overall formulas 2 had scored higher than formulas 1 and formulas 3 (p≤0.05). Then formulas 2 was selected for the next step study. Comparison of old frozen Chaya vegetable cream soup formulas 2 and adjusted formulas 2 which according to expert advice by blending from 2 minutes to 4 minutes add unsalted butter add cooking cream and reduced pepper from 5 grams to 3 grams in terms of color aroma taste and overall liking are not different except the texture of the soup. Frozen Chaya vegetable cream soup has moisture 87.60% fat 1.45% crude fiber 1.84% ash 1.07% protein 1.11 % calcium 85.37 mg/kg iron 0.44 mg/kg potassium 128.34 mg/kg and total fiber 1.19 mg/kg. Frozen Chaya vegetable cream soup has light green color and cyanide substance still was 0.1 mg/kg which is safe for the consumer. Comparison of preference score between Frozen Chaya vegetable cream soup and non-frozen found that was no difference (p ≤ 0.05). The consumer test of them are female between 25-35 year old graduated bachelor degree a company employee and income 20001-25000 THB per month consumer from this group are satisfied with high scores for cream soup. The consumer is interested in frozen Chaya vegetable cream soup because this is a new product and price 45 THB is valuable. The consumer would like to have a frozen Chaya vegetable cream soup sole at the supermarket. The cost for the product per 1 cup is 19.07 THB and the sale price is 45 THB.
