This abstract is aimed to study the problems and barriers in receiving the business administration students into co-operative education apprentice in accordance with the firms’ ideas on organizing and working processes qualifications knowledge and competence in the field of study. Population is the entrepreneurs or controllers who accept 180 fourth-year students of academic year 2255 to the internship programme. The data collection is using questionnaires. Statistics used in the data analysis are percentile means and stand deviation. The research results are as followed: 1. The problems and barriers on organizing and working process are at the high level. This implies that the firms are unable to coordinate with the institution to define and get the students ready before implementing.2. The problems and barriers on the qualifications of cooperative study students are at the high level. This implies that those students are unable to make decision to solve problems during internship. 3. The problems and barriers on knowledge and competence in their fields of study are at the high level. This implies that students are unable to communicate well both verbally and alphabetically in Thai and foreign languages.

The optimum conditions of extracting pectin from vegetables and fruits are apples grapefruit lemons and bananas were studied. It was found that pectin from grapefruit peel gave good physical property white and has a relatively highest yield. Therefore in this study was interested to choose grapefruit peel as raw materials to optimum the conditions of pectin extraction. In the process of pectin extraction the temperatures of the extraction were studied at various 50 60 70 80 and 90 ?C by using hydrochloric acid for 24 hours. It was found that when the temperature increased the pectin extract was increased while at 80 and 90 ?C have a similar effect. After that pH conditions of the extraction were studied by various acids such as hydrochloric acid nitric acid and acetic acid at the same concentration of 1.0 molar at 80 C for 24 hours (1440 minutes). The results found that hydrochloric acid gave maximum pectin extracted yield. Finally the extraction times were studied at 30 60 90 120 and 1440 minutes using 1.0 M hydrochloric acid. From this work can optimized the pectin extraction condition as of 80 C and the extraction time was 90 minutes that gave maximum yield of pectin. At the otherwise the times of extraction have no effect to the amount of pectin. The potential from this study had satisfactory results can be used to improve the extraction of pectin system.

This experimental research was to test a performance of flat-plate solar collectors using biodiesel as a working solution with a solar thermal system. The purposes were to promote a biodiesel use as an alternative fuel for higher efficient heat energy and as an added renewable energy for a production process and to provide a guideline in education and for development in the future. The experiment was to test a performance of flat sheet solar collectors using ASHRAE STANDARD 93-2003 and to test a thermal potential of 12 litres by volume of biodiesel in a 2 m2 flat- plate solar collector used as heat source of the system. Thus biodiesel was used as a working solution with a flow rate of 2.4 litre per minute and the test duration was between 09:00 am. and 03:00 pm. The result revealed the performance values of the flat-plate solar collector used in this experiment as FR( ) = 0.958 and FRUL = 15.02 W/m2K. The temperature of biodiesel in the solar thermal system increased from 33๐C to approximately 80-90๐C varied with solar radiation values. However; the mentioned degrees could be efficiently applied in biodiesel production process as a main heat source or a supplemental heat source depending on appropriate variables.

The purpose of this research was to construct the Computer Assisted Instruction Package for Computer Instructional Package for Drawing 2 dimension Subject using subject by evaluating the efficiency of the Computer Assisted Instruction Package Tools used for this research were Computer Assisted Instruction Package for Drawing 2 dimension Subject using multimedia quality test and questionnaire for learner’s satisfaction. The sample group was 30 students from Department of Machine Shop Pratumtani Technical College. The analysis between pretest and posttest was learning achievement higher scores This could be concluded that the computer self study package for Drawing 2 dimension Subject using can be used as a learning package.

One of major missions of Rajamangala University of Technology Phra Nakorn is to promote studentscreation of research invention and innovation in order to add values to production sector and national academic service. The Promotion of Inventions and Innovations by Young Generation Project has been since 2008 initiated to provide necessary support development of undergraduate students works. The project aims to promote and improve students invention and innovation as well as to encourage national publication. This project has enhanced students professional expertise which would develop into Hands-on graduates. Results of the project were presented at national level and severaltools devices and products had been produced and evidently utilized to improve production process of communities and industrial sector. The 1st Rajamangala University of Technology Phra Nakhon Innovation and Technology Exhibition is another activity that has presented results of the project to public. The activities included an exhibition of students innovations ana technology a forum on Hands-on graduate development and a contest of students works. This initiation clearly corresponds with the mission to promote students creation of innovation in oder to produce hands-on graduates who have curiosity persistence technological expertise and morality in accordance with the university identity.
