This research aims to investigate the efficiency and quality of young rice planting machine which is suitable for the North Eastern part of Thailand. The investigation applies the notions of planting young rice manually by farmers into the design of a battery-driven young rice planting machine. The researcher started with the study of transplanting methods of agriculturists in the North Eastern part and the design principles of young rice planting machine. Next the components were calculated and engineering design was drawn. Then the machine was tested in terms of its efficiency and quality. The data were analyzed in terms of means. The results show that the efficiency of the machine regarding planting performance is 90 % the appearance of the machine functions applications engineering and safety achieve the average point of 3.70 which is considered satisfactory.

The purposes of this research were to develop 10 items of the packages of bakery’s banana flour and to conduct the technology transfer of those packages for the community. The research process involves with package pattern analysis monitoring and operating package design making package sample evaluating package sample finishing the package target group setting creating the research methodology investigating need analysis training course setting conducting the training course and data analysis. The results of the study were 10 styles of the packages. It was found that the mean of the satisfaction evaluation was at 3.76. Need analysis for bakery courses are mostly found in brownies. There was significantly difference between pre-test and post-test scores of the experiment at 0.05 level of significance. The mean of the groups’ achievement evaluation was at 3.95-4.18. Program and training process evaluation was qualified as the mean was 4.62 and 4.54 respectively.

The purposes of this operation research were to develop the packages of Thai herbal cookies and to conduct the technology transfer of Thai herbal cookies’ packages for the community. The research process which involves with packages’ pattern analysis monitoring and operating packages’ design making packages’ sample evaluating packages’ sample finishing the package target group setting creating the research methodology investigating need analysis training course setting conducting the training course and data analysis. The results of the study were 11 styles of herbal cookies’packages. The mean of the achievement in satisfaction evaluation was at 3.92. Need analysis for cookies courses are found in lemon grass cookies kaffir lime leaves cookies ginger cookies mixed herbal flavour and coriander cookies respectively. There was significantly difference between pre-test and post-test scores of the experiment at 0.05 level of significance. The mean of the groups๛ achievement evaluation was at 3.50-4.49. Program and training process evaluation qualified as the mean of the products and their packages was 4.28 and 4.34 respectively.

This research was concerned with dye extraction from the bark of eucalyptus and application for silk and cotton fabric dyeing. Silk and cotton fabrics were treated with premordanting process before dyeing experiments in order to facilitate dye absorbency of fabrics such as silk dyeing at 90ฐC for 40 minutes and pH 4 cotton dyeing at 60ฐC for 40 minutes and pH no adjustment. The best result was achieved when liquor ratio between fabric and dyed solution as 1:30 was employed. Silk dyed in the solution extracting from the bark of eucalyptus with mordant compound displayed yellow to brown colour except fabric using fesrrous (Fe) mordant exhibiting the shade of dark brown to grey. For cotton fabric the shade of yellow to orange was obtained except fabric using ferrous (Fe) mordant displaying the shade of pale grey to gray. Silk and cotton fabrics treated with pre-mordanted and dyeing process has presented the properties of colour fastness to washing water and perspiration from good to very good level whereas colour fastness to light and rubbing was from fair to good level.

The purpose of this research is to study the factors affecting the students๛ achievement and to create the model of the achievement predictive equation on Research Methodology subject Rajamangala University of Technology Phra Nakhon Chotiwet Campus. This research is a correlation research. The population are the third year (4-year-Programme) students of Chotiwet Campus majoring in Food and Nutrition totaling 133. The results of the study revealed that there were two factors affecting the students๛ achievement on Research Methodology as follows : (1) cummulative grade point average and (2) students๛ problem of how to adjust to the study environment. The above-mentioned factors can be formed as model of the Research Methodology achievement predictive equation as follow yˆ = 11.079+3.349 x1 - 1.081 x7
