Advertisement and admission of target applicants who will be new undergraduate studentswill help to reduce costs promote or recruit off- campus as well. The decision tree Technique can be used to develop models to forecast numbers of new students in the classification rules for accuracy. It helps to decide on the form and place in admission of new students to meet the target even more. The seven models developed by using the rules of classification techniques decision trees were built and tested with different sampling methods: 3 models of k-fold cross-validation 3 models of percentage split and a model of training set and test set. The study result for forecasting new students via model developed by training set and test set method is higher performance than model developed by other methods. It was shown that the efficiency was 94% the precision was 94.3% the recall was 94% and the F-measure was 93.7%. Thus this model is accurate in forecasting numbers of new students using the classification rules with decision tree technique.

The objectives of this study are to study the usage of the marketing mix factors application for decision making to select wedding consult services at Bangkoknoi district in Bangkok metropolistan to study the decision behavior when selecting wedding consult services as well as comparison of the marketing mix factors in selecting wedding consult services classified as per- individual factor.

The result from hypotheses testing showed that the sample group with different age education average income and career tend to use the marketing mix factors in selecting wedding consult services differently with a significant statistical difference of 0.05 while the sample group with different gender tend to use the marketing mix factors in selecting wedding consult services indifferently with a non-significant statistical difference of 0.05.

This research was a survey research. The objective was to study the factors of social adjustment of students of the Faculty of the Industrial Education Rajamangala University of Technology Phra Nakhon. The data analysis based on statistic data the average percentage standard deviation t-test and analysis of variance. The results can be summarized as follows: the factors of social adjustment of Industrial Education students are at the moderate level. The results of factor analysis are 1) Students with different genders and age have the overall indifferent social adjustment ability. 2) Students who graduated from different field of study have the overall different social adjustment ability . The students who graduated from vocational certificate program have the overall higher social adjustment ability than students who graduated from general education program. 3) Students with different years of birth and different family status in society have the overall indifferent social adjustment ability. 4) Students with their parents in different occupation and different average-income-per-month families have the indifferent overall social adjustment ability and 5) Students with different family characteristics have the overall different social adjustment ability.

Nowadays electrical current measurements can be categorized into two methods; direct and indirect measurements. The small amount of electrical current can be directly measured by means of electrical current instrument whereas the current of high voltage cannot directly be measured by means of any physical contact of an instrument on the other hand it can be indirectly be measured through voltage transformer by stepping down voltage method in which cannot be realized economically and practically. This paper presents a method of measuring high voltage current by means of Rogowski coil detecting induced electromagnetic ware compensating unwanted induced current and finally amplifying. The results are that the reduction of measurement time and cost of purchasing the instrument.

This research aims to study the marketing mix factors that influence consumers’ purchasing decisions and to compare the marketing mix factors that influence purchasing decisions of consumers in the Seacon Square shopping mall.
