The purpose of this research was to: 1) use Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject 2) compare academic achievement of students taught with the multimedia instruction and students taught with the conventional method and 3) study student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject. A sample of 60 secondary 1 students attending Sinakharinwirot University Prasanmit Demonstration School was chosen using Cluster Random Sampling and were classified into 2 groups of 30 students; the first being the experimental group instructed with the Multimedia Development technique and the second being the control group instructed with conventional methods. The instruments of this research include lesson plans multimedia an evaluation form to track the multimedia efficiency a practice evaluation form and a questionnaire surveying student satisfaction. The statistics used for the data analysis were percentages mean standard deviation and a t-test. The results were as follows: 1) using Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject achieved the efficiency of 82.14/80.06 2) the students taught with the multimedia technique have greater after learning achievement than those taught with the conventional method; statistical significance was at the .05 level and 3) the student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject in high level is (x̅ = 4.42S.D. = 0.54)

Rail transport is a type of transportation that strongly influences economic due to its ability to transport a large number of passengers and products per trip relying on diesel-electric engines. The objectives of this thesis were set to investigate and develop the electrical performance tracking system of long-distance diesel electric locomotives and compare the electrical performance measured by the diesel electric locomotive performance tracking system and measured from the measuring instrument at Diesel Engine Maintenance Station in Bang Sue. The electric diesel locomotive no. 4513 (Cummins KTA50-L) was selected as the study subject of the experimentation. The results showed that the power loss of the diesel electric locomotive from the conversion of alternating current to direct current was inversely proportional to the engine speed. The power losses between the low and high engine speeds were equal to 77.11 and 2.49 percent respectively. The above data reflects the limitation of diesel electric engine performance and should lead to the construction of a database for making decision on the right engine selection suitable for the towing load of the locomotive.

The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.

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.
