The objectives of this research were to find the distribution of food demand for laying hens and to find the optimum amount of that food production which had minimum cost. The data consisted of customer purchase orders for the food of laying hens price of food for laying hens cost per unit for the food inventory cost related to food of laying hens in which the food was out of stock such as fine overtime urgent purchase for material. They were collected in 2008-2009 form a factory in Nakhonratchasima province. The collected data were analized in order to explore the distribution of the monthly food demand for the laying hens and to see the rate of inventory per unit. The results were used in the stochastic linear programming model for aggregate planning in which the optimum production minimum cost could be obtained. Programming algorithm in MATLAB and tools in Linprog software were used to get the solution. The distribution of the food demand for laying hens and the random numbers were used in the model. The study found that the distribution of food demand for laying hens every month has normal distribution (January to December). The monthly average amount of production from January to December were 10936.94 12913.74 11898.12 13096 15443.26 14916.33 10322.64 10818.21 11393.11 11700.72 9706.05 and 11702.05 respectively. The minimum total cost average for 12months was Baht 62422386.98.

This is a survey research. Its aim is an attempt to study and present the problems and Utilization of Instruction Innovations of Faculty of Industrial Education’s lecturesRajamangala University of Technology Phra Nakhon. The data collections were selected from population sampling of the Faculty of Industrial Education which consist of four departments with 38 lecture samples by using the purposive sampling. Research Methodology To study the problems and utilization of instruction innovations of the Faculty of Industrial Education’s lecture questionnaires were provided to collect data by using the average percentage value of standard deviation T-test and F-test technique. The following research results are : 1. The sexual differences of lectures has no any problems in using instruction innovation. 2. The different age levels of lecture have no problems in using instruction innovation. 3. For the lecture’s educational background there are no any problems in using instruction innovation. 4. Lectures in different departments of Faculty of Industrial Education have no any problems in using instruction innovation. 5. Lectures of Faculty of Industrial Education have a problem in using instruction innovation is at the moderate level. 6. According to the research results the most internal important problematic factor is the attitude’s lecture toward the necessary of instruction innovation. 7. The most external important problematic factor is the lack of financial supporting on production instruction innovation. 8. Lectures under the Civil Engineering and Mechanical Engineering department have problems in difficulty of using instruction innovation more than Electrical Engineering’s lecturers.

The objectives of this research were to 1) study current situation perceived problems and developmental method of Learner-Centered Teaching-Learning Approach of instructors of Rajamangala University of Technology Phra Nakhon 2) compare the current situation of Learner-Centered Teaching-Learning Approach of instructors classified by faculties and 3) propose developmental method of Learner-Centered Teaching-Learning Approach of instructors of Rajamangala University of Technology Phra Nakhon The sample studied were 257 instructors from all faculties who returned the complete questionnaires to researcher and 2.412 students selected by stratified sampling. The data was collected through questionnaires constructed by researcher. The statistics used for data analysis were mean standard deviation one way analysis of variance and Schffes multiple comparison method. The results were as follows: 1. Learner-centered Teachng-Learning Appoach of instructors of Rajamangala University of Technology Phra Nakhon was at high level (= 3.36). Regarding problems affected learner-Centered Teaching-Learning Approach of instructors it was found that instructors positive attitude toward Learner-Centered Teaching-Learning Approach was at intermedate level and instructors knowledge concerning the Approach was also at intemediate level. moreover it was found that instruclors possessed problems in relation to facilitate faclors of Learner-centered Teaching-learning Approach at intermediate level. 2. Instructors from different facuities had statistically difference of Learner-Centered Teaching-Learning Approach with a level of .01 significarce. 3. The significance of Learrer-Centered Teaching-Learning Approach should be stressed. In additon the better understanding of Learner-Centered Teaching-Leaming techiques should be trained to all instructors Besides the students should be encouraged to study from outside resources more and more.

The purpose to this research was to assessment the graduate Diploma Program of Teaching Profession at Rajamangala University of Technology Phra Nakhon Faculty of Industrial Education of the curriculum used. Research population consisted of graduate students diploma degree graduate their superiors and instructors. Simple random sampling gave the sample size of 549 people were selected from purposive sampling. The research tools were a questionnaire and a focus group discussion recording form. Data analysis employed basic statistics of frequency mean and percentage including content analysis for qualitative data. The findings of this research were as follows: 1) Primary components of the curriculum were suitable at high level. 2) Course structure and content was suitable at high level. 3) Characteristics of lecturers were suitable at high level.4) Instructional and evaluation activities were suitable at high level. 5) Factors contributing to the teaching of the course were also found suitable at high level. On the contrary Journals related to inadequate service and problems of withdrawal teaching materials. However the curriculum development should be updated to suit the needs of society and science is always developing.

This paper is a survey research. The objective is to study the factors of Social Adjustment of Technical Education Faculty Students B.S. of Technical Education (5 years curriculum) Faculty of the industrial education Rajamangala University of Technology Phra Nakhon. The random sampling is conducted within the full-time students from 3 majors. The random sampling technique in this paper is derived from Krehbiel-Morgan table. The total number of sample is 167 students. Research Methodology This paper uses the survey method to collect the data. The data analysis process is based on the average percentage value of standard deviation and t-test F-test techniques. The research results can be summarized as follows: 1. Students with different genders have overall social adjustment ability indifferently. 2. Students with different ages have overall social adjustment indifferently. This implies that age is not a factor in social adjustment. 3. Students who graduated from different curriculum have overall social adjustment ability differently. The students who graduated from vocational-qualification curriculum have overall social adjustment ability higher than students who graduated from academic-qualification curriculum. In specific aspect of social adjustment to classmate the result is also the same. 4. Students with different sequence of birth have overall social adjustment ability indifferently. 5. Students with different family status in society have overall social adjustment ability indifferently. 6. Students with their parents in different occupation have overall social adjustment ability indifferently. 7. Students with different average-income-per-month families have overall social adjustment ability indifferently. However in specific aspect of social adjustment to general person the students with higher average-income-per-month families have social adjustment ability better than the students with lower average-income-per-month families. 8. Students with different family characteristics have overall social adjustment ability differently. The students with large family have overall social adjustment ability higher than students with small family.
