The objective of this research was to study present and future desirable characteristics of industrial teachers Consequently developed a role model to encourage desirable characteristics of industrial teachers who graduate from RMUTP. Multi-step randomized population is categorized into three groups defining size from tabel of Krejcie & Morgan. The first group is 120 administrators from government and private vocational schools located in Bangkok Metropolitan and surrounding area. The second group is 291 vocational students. The third group is 165 vocational student possessors. The total number of population is 576. The instrument was a questionnaire for each sample. All data were analyzed to determine statistical results and presented in tubular form. A focus group meeting of 15 lectures from the Faculty of Industrial Education was organized. The group meeting suggested a role model for future desirable characteristics of industrial teachers. The study result showed that most population from those three groups highly agreed in three aspects namely Personality Ethics and morality and Professional skill aspects. The focus group meeting suggested improving the curriculum and also the activities. The activities were needed to improve both curriculum activity and teaching activity of lecturers.

The purposes of the research on soy milk product mixed with carrot were to study the preparation of soy milk carrot juice extraction appropriate ratio of soy milk to carrot juice and sugar content shelf - life and consumers’ acceptance of the product. The study was focused on the product’s physical quality chemical composition sensory quality and micro-organism content. The results of the research revealed that soy milk with soy bean : water at 1:4 (by dry soy bean weight)used in extraction process; blanching of carrot prior to extracting which yields 70.31% of the juice and 4580 μg . (763.33 R.E) beta - carotene per 100 grams of carrot which is a higher amount than extracting fresh carrot ; the ratio of soy milk to carrot juice at 70:30 and 5% of sugar content by weight are appropriate in soy milk mixed with carrot production. The L*value a*value and b* value were 66.79 25.24 and 39.25 respectively. The viscosity was 17.33 centipoint; total soluble solid was 11.67 brix; and pH was 6.25. The acceptance scores on color flavour texture and overall preference were 7.98 8.00 7.93 and 8.05. This means preference on color and texture was moderate; the preference on flavour and texture was very high. For chemical composition it was found that there were 71.08 kcal. energy 4.40 g. protein 1.56 g. fat 9.86 g. carbohydrate and 1378 μg.(229.67 R.E.) beta-carotene per 100 grams. The cost of raw materials was 6.41 baht per 180 ml./bottle. The study of consumers’ product acceptance showed that most consumers had knowledge on nutrition; they accepted and had preference on the product at the moderate level. The price of 12.00 baht per 180 ml. bottle was accepted. It was also found that there was no physical or chemical change of the product when kept at 70C for 14 days. Total bacterial count was 4.8x10 CFU/cm3 when compared to Soy Milk Thai Community Product Standard (SPC. 529/2004) which specified that not exceeding 1x104 CFU/ cm3 should be found in the product. It was evident that the product was still safe for consumption when kept for 14 days.

This research aims to study Student and Staffs expectancy and gratification from exposure to Rajamangala University of Technology Phra Nakhons Internal Public Relation Media by using survey research. The questionnaires are used to collect data from a total of 400 samples. Percentage Mean Standard Deviation One way ANOVA and analysis of variance are used for statistical analysis of data with the level of significance at 0.05. The result of this study shows that: 1. The difference in sample status has no difference effect upon the exposure to Rajamangala University of Technology Phra Nakhons Internal Public Relation Media. 2. The difference in sample status has difference effect upon the expectancy to Rajamangala University of Technology Phra Nakhons Internal Public Relation Media. 3. The difference in sample status has difference effect upon the gratification to Rajamangala University of Technology Phra Nakhons Internal Public Relation Media.

The objective of paper is to design and develop solar hybrid for common usage heat energy between sunshine and heater The technology improvement of integrated solar dryer cabinet aims to prove that the solar energy for thermal purpose is most useful alternative device for energy conservation which helps environment and pollution protection. It can also be an effective equipment for industrial drying process of herbal plants and products in term of dehydration humidity reduction and fungus termination. The use of solar dryer cabinet can serve the high demand in the market of Thai herbal products which some of which are also used as detoxification. Solar Hybrid Energy Oven choose between infrared heater and DC heater. The outer structure of solar drying cabinet is made of aluminum sheet of 60 cm. wide 60 cm. long and 80 cm. high. The inner box is coated with black paint. The experimental process and data collection of solar radiation was carried out for 15 days. The humidity value measurement was conducted during a 5-hour drying process with data collection at every 20 minutes. The herbal plants used in the experiment are lemongrass pandanus citrus hystrix leaf red paprika and gotu kola. The data collection hours are from 10.00 am to 15.00 pm and the finding shoes that the highest temperature in the cabinet reaches 99 degree Celsius. The fastest dehydrated and dried process is pandanus whose initial humidity value is 589.6 % dry basis and humidity mean after drying process is 3.4 % dry basis. Lemongrass contains the second highest initial humidity value which is 566.6 % and humidity mean after drying process is 3.3 % dry basis. This indication confirms that the technology of solar energy combined with infrared heater cal most effectively generate the heat in the cabinet to serve the drying process.

This research aims to survey about the opinion of the enterprises in Bangkok area that being effect on the image of the Rajamangala University of Technology Phra Nakhon by using Survey Research. The Questionnaire is used to collect data from a total of 400 samples that are the enterprises in Bangkok area by using Stratified Random Sampling. And statistics are used data analyses as Percentage Mean and Standard Diviation. The outcome is as : The result of this study shows that the opinion of the enterprises to the image of the Rajamangala University of Technology Phra Nakhon is positive that is mean at 3.19 the organization image is mean at 3.36 and the learning and teaching management is mean at 3.33. The opinion of the samples to the image of the Rajamangala University of Technology Phra nakhon are to be the reliable firm and famous university to have leadership. The graduated students can use and apply knowledge in their work. Next the university has many faculties and programs for studying which are consistent to the labor market needs. After that the university supports the students to do the good activities. Finally the news and information which shows on mass media is good.
