The objectives of this research were to study the effect of the substitution of sinin rice flour to wheat flour in the crust of the flaky Chinese pastry (Kha-Nom Pia Kularb) on the physical quality the chemical composition and the consumer acceptance of the developed product. The ratios of sinin rice flour substituted for wheat flour (w/w) at 0:100 (control) 10:90 20:80 30:70 and 40:60 were studied. The results showed that increasing substitution levels caused darker purple lower cohesiveness and more difficult for shaping. Additional the higher level of substitution the more decreased of product’s size specific volume and lightness (L*) of crust and filling. According to the texture profile analysis when the ratio of sinin rice flour in the product increased the hardness springiness and cohesiveness of the product decreased while the chewiness increased. Sensory quality evaluated with 9-point hedonic scale by 55 panelists. The crust of product which was formulated using a ratio of sinin rice flour: wheat flour at 20:80 had liking score higher than the others with moderate liking score. Analysis of chemical compositions (100 g product) showed that the contents of moisture protein fat ash carbohydrate and dietary fiber as 16.37 7.09 26.30 0.62 49.62 and 2.27 g respectively. The total calorie was calculated as 463..54 Kcal/100 g. Furthermore this product provided anthocyanin 6.5 mg/100g (dry basis). Moreover consumer acceptance test with 120 consumers revealed that the overall liking of this product was like highly and 98.0% of consumers accept it besides 96.7% of them decided to buy it.

Development of prototype products from waste rice for teenage consumer. The purpose of this study was developing formula and prototype of waste rice for food production. The waste rice could be used as rice in 100% for 3 products such as Khao Tang Rice Crackers and Sticky Rice Coconut Cream. The suitable condition for Khao Tang was using waste rice as 110 g. and seasoning 10%. The result of physical and chemical analysis showed that: products have orange bright color hardness cripyness and not rancidity. The percentage of moisture fat protein crude fiber ash and carbohydrate content 4.02 ± 0.06 20.12 ± 0.05 9.36 ± 0.04 2.58 ± 0.12 4.30 ± 0.11 and 59.62 ± 0.09 respective. The suitable condition for Rice Crackers was using waste rice as 130 g. storage in room temperature at 24 hr. After that place to microwave at 20 sec. %. The result of physical and chemical analysis showed that: products have orange bright color Tom Yum seasoning for delicious hardness cripyness and not rancidity. The percentage of moisture fat protein crude fiber ash and carbohydrate content 6.69 ± 0.03 1.65 ± 0.06 5.23 ± 0.07 0.93 ± 0.13 1.37 ± 0.08 and 84.12 ± 0.05 respective. The suitable condition for Sticky Rice Coconut Cream was using coconut milk (UHT) as 175 g. storage in freeze at 24 hr. After that place to microwave at 30 sec. %. The result of physical and chemical analysis showed that: products have white-yellow bright color softness and coconut sweet taste. The percentage of moisture fat protein crude fiber ash and carbohydrate content 43.55 ± 0.03 6.29 ± 0.02 3.21 ± 0.03 1.20 ± 0.06 0.50 ± 0.09 and 45.24 ± 0.05 respective. The shelf life of 3 products are more than 2 months and consumer acceptability like moderately product.

The objective of this research was to design and development of a continuous flow paddy dryer with infrared radial radiation technique. The prototype of dryer consists of two concentric circular cylinders cylinders which the paddy drying chamber is height of 1 m. The inner cylinder has diameter of 26.5 cm made from glasses and outer cylinder has diameter of 29.5 cm made from perforated (1.75 mm) steel sheet. At the center of cylinders installed 1200 w of electric infrared heater. A hopper was installed on the top of the chamber while 120 w of blower and paddy flow control were installed at bottom of chamber. The performance of the dryer in terms of specific energy consumption (SED) drying rate (DR) and quality of paddy i.e. head rice yield (HRY) and whiteness index (WI) were evaluated by drying 15 kg of paddy with initial moisture content of 23-26% (w.b.) by using the drying conditions of 80oC of drying chamber temperature 1.075 m3/min of air flow rate and 0.837 1.228 1.875 and 2.308 kg/min of paddy flow rate. The results found that paddy flow rate at 1.875 kg/min is the optimum condition because gave the highest DR lowest SEC and rice qualities (HRY and WI) closely to control.

The objective of the research was to study suitability of professional competences indicators for mass communication office in digital age. The data were collected by using questionnaires sampling from 600 samples who were mass communication officers and lectures in mass communication universities. Data analysis employed frequency percentage arithmetic mean □(-/×) standard deviation (S.D). The research results revealed that there were the mass communication officer professional competences were 44 indicators including 10 indicators of printed media competences 13 indicators of radio and television broadcasting media competences 10 indicators of film media competences and 11 indicators of digital media competences.

This study aimed 1) to develop an effective learning video media on how to make Baisripakcham for Home Economics Major vocational certificate students 2) to compare pre-test and post-test results using learning video media on how to make Baisripakcham and 3) to study students satisfaction in using learning video media on how to make Baisripakcham. Sample group was 40 second year students taking Home Economics under vocational level at Sukhothai Vocational College. These students were studying in the second semester of 2017 academic year. The result showed that content quality of the developed learning video media was very good ( x = 4.65) and the quality of video media was also very good ( x = 4.68) The analysis of learning achievement showed that the average post-test learning achievement was higher than the average pre-test learning achievement. When pre-test and post-test scores were compared using t – test found that t = 21.63. This showed statistically difference at .05 significance. Learners satisfaction of the video media was at highest level ( x = 4.56). It can be summerized that the learning video media helped students attain higher learning achievement. Learners level of satisfaction in using the learning video media was highest. The media can be used in learning and teaching Baisripakcham course in the vocational certificate curriculum of Vocational Education Commission Office.
