The purposes of the research were to create and find efticiency validation of computer assisted instruction focused on the fundamental of welding for the standard 90/90 and analyze the students learning achievement after using computer assisted instruction. The samples were the 20 first year Bachelor of Engineering Program in Industrial Engineering Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the fundamental ofwelding and analyzed the students learning achievement after studying. The result revealed that the computer assisted instruction efficiency was efficient for standard 90/90. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.

The purpose of this research were to follow up the Graduated students and to examine the satisfaction of the Enterprises towards the efficiency of work perfonnance of graduated students from Rajamangala University of Technology Phra Nakhon in!999 -2004 The population of this research is about 500 bachelors who graduated in academic years 1999 -2004 and the enterprises who oversee the graduates from the faculty of Home Economics Rajamangala University of Technology Phra Nakhon. The instruments used for collecting data were the questionnaire about working data and the questionnaire about the satisfaction of the enterprises for examining working performance covering 3 aspects; capacity ofworking morality human relations attitude towards their work and responsibility for career convention . They are consisted of rating scale and open -ended questions The statistics used to analyse the data are percentage mean and standard deviation The results revealed that I. The graduated students who graduated between 1999 -2004 have almost worked as employees. 2. The satisfaction level towards their faculty were high. 3. The satisfaction level towards their university and the Faculty ofHome Economics were at the highest level. 4. The overall satisfaction of the enterprises towards work perfonnance of the graduated between 1999 -2004 was at high level. For individual items consideration found that the satisfaction level were at high level in morality human relations attitude towards their work and capacity in working respectively.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the practice to record data for report writing for t Ie standard 90/90 and analyze the student learning achievement after using (computer assisted instruction. The I samples were the 20 first year Bachelor of Science in Technical Education st~dents enrolled in Industrial Engineering Rajamangala University of Technology fhra Nakhon North Bangkok Campus. The Researcher experimented by using prete~t and then using the computer assisted instruction focus on the practice to Iprepare specimens in learning next the students did the posttest. After that the resrarcher calculated to find the computer assisted instruction efficiency and analyzed:! the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 90 / 90. And after studying by using computer assisted instruction tme students learning achievement increased significantly at 0.05.

The purposes of this study were to examine the teaching efficiency of instructors of Rajamangala University of Technology Phra Nakhon North Bangkok Campus in six Factors such as Knowledges Teaching Using of teaching aids Personalities the Relationship between Instructors and Students and Assessment. The sample included 334 Bachelor Degree Students of Rajamangala University of Technology Phra Nakhon North Bangkok Campus of the academic year 2005. The variables were studied and classified into vocational staffs and General Education Staffs. The data was collected using a five-point Likert type questionnaire. The questionnaires were distributed to the samples and 100 per cent were returned. The mean standard deviation and t-test were Statistical methods applied it was fond that the ottal efficiency of instructor teaching in six factors : Vocational and General Education staffs were high for each item it was implied that the teaching efficiency of Vocational Staffs were high: but that of General Education Staffs were averaged i item 4 : Reviewing and item 5 ; Summarizing. The total efficiency of instructors teaching in 6 aspects suggested that they were significantly over rveraged at .01 level. The total efficiency of instructor knowledge were significant different at .01 lever. for each item ti was found that they were significantly different at .01 lever in item 2 Example giving item 3 Question answering and item 5 : lmplications. The total efficiency of instructors teaching were significant different at .01 level. for each item it was found that they were significantly different at .01 level in Teaching Factor ; item 1 : Student questioning and answering item 2 : Teaching by seguential order item 4 : Reviewing Item 5 : Summarizing item 6 : Appropriated teaching pedagogy item 7 Adaptation of Teaching approach. The total efficiency of instructors teaching media was significantly different at .01 level. For each item found that it was significantly different at .01 level in Teaching Media Factor; item 1 : Suited for the students abilities and knowledge item 2 : interesting and modern media item 3 : Media Preparation and item 6 :The media assisting students to understand the lessons. The total efficiency of Relationship between Instructors and Students was significantly different at .01 level For each item it was found that they were significantly different at .01 level in Relationship betweeen Instructors and Students factor ; as in item 2 : Students name Membering item 3 : Students Knowledge follow up and item 5 : Students Counselling. For the efficiency of instructors Personality and Assessment Factor there was no different by totally and each item

This industrial research was studied an improvement of efficiency in natural fiber production plant. The objective was improvement process by using IE techniques which this method was once green technology for industrial problems solving. Now process had build-up in process (WIP) due to unbalance times between trimming station and visual inspection of station. Therefore the research studied work of staffs; time study and data analysis through 5W1H were used for analysis of WIP root cause. The cause of problems founded were the transportation loss of between section had over necessity and loss of visual inspection for repair. Therefore it had bottleneck in process. Consequently the researchers applied ECRS in each working processed by separation of repair station. Repairs of items were isolated from the main flow path of the process. Calculating of work flow rate was used for identified operator for repair station. As a result of the above production improvement Times of visual inspection in a lot was decrease from 283.84 hrs to 160.19 hrs. It was decreased in 43.56%. In addition the effect of separation from the repair process made the total times of all process was decreased from 792.78 hrs/lot to 669.14 hrs/lot. It was decreased in 15.60% and decreased work in process had from 17 lots/day to no work in process.
