This research study the purposes of the research are to:1) students learn the fundamentals of vocational education Suphanburi education in the field of food and nutrition Vocational certificate (vocational certificate) and the Diploma (Diploma.) 2) a study of student satisfaction and 3) Comparing the level of student satisfaction by overview of respondents. The samples college students Suphanburi the sample-specific .The students who are studying in a vocational certificate (vocational certificate) Year 2 and Year 3 major food and nutrition of 78 people and students who are studying at Diploma (Diploma). Year 1 and Year 2 major food and nutrition of 26 people a total of 104 people. The statistics used for data analysis the frequency percentage mean standard deviation t-test and ANOVA. The datas were analyzing by a computer program. The results showed that : respondents were satisfied in studying food and nutrition school Suphanburi the overall high level considering each side and item at a high level. Comparing the level of student satisfaction by gender age and the average income of a student per month overall and each aspect is no different. For to the years of study and profession of parents there is satisfaction in studying food and nutrition overall and the difference was statistically significant level. 05
เครื่องต้นแบบอุปกรณ์เตือนแจ้งการทำความสะอาดแผงโซล่าเซลล์ เพื่อให้ประสิทธิภาพการจ่ายไฟฟ้าสูงสุด
Research presents the design and construction of a prototype device alert to clean the solar panels. The measure monitoring of dust and blocking dirt surface of solar panel causes generation Energy low efficiency the devices are alerted to clean solar panel to ensure generation Energy highest efficiency and reduce the cost of solar cell cleaning which will be done 12 times a year. Researchers have introduced electrical and electronic technology with solar panels to provide a reference. Take an installed prototype in process with solar panel energy factory. After that clean the panel referred to the morning every day. This prototype will be processing performance comparison between the solar panels reference with the solar panels factory every day and results via the Internet and record the data in memory. The results of this research found that. Efficiency of electricity production is down 9% as 3 months and 10.47% of the year due to impurities. Dust cover doing have been cleaned twice the efficiency of the electricity production has remained high. This will alert you that washing does not have to be done 12 times as practiced in a solar farm reducing costs 10 times a year.
การพัฒนาผลิตภัณฑ์ผ้าที่ใช้สำหรับบนโต๊ะอาหารจากผ้าฝ้ายบาติกมัดย้อม ด้วยการตกแต่งสะท้อนน้ำ
Development of table cloth products from Batik tie-dyed cotton fabric with waterproof finishes aimed 1) to study waterproof finishes process to Batik tie-dyed cotton fabric 2) to test physical properties of Batik tie-dyed cotton fabric and 3) to study satisfaction of consumer to table cloth products from Batik tie-dyed cotton fabric with waterproof finishes. Prototype of table cloth products and questionnaire was used as the tools in this research. The samplings for this study were the 323 consumers from accidental sampling in Faculty of Home Economics Technology and Faculty of Architecture and Design Rajamangala University of Technology Phra Nakhon. Data was analyzed by percentage mean and standard deviation. Reported of physical properties testing of Batik tie-dyed cotton fabric with waterproof finishes as follows; colorfastness to water testing changed in color was grade 4-5 dimensional changes after laundering testing decrease 1.14 percentage in the length and 0.48 percentage in the width colorfastness by hot pressing testing; dry pressing damp pressing and wet pressing changed in color was grade 4-5 and water resistance testing found that surface area having wet patches small. The results from study satisfaction of development of table cloth products from Batik tie-dyed cotton fabric with waterproof finishes were found that; the sample age between 21-30 years bachelor degree education level status of student and monthly income 100001-20000 baht. Consumers purchased and used Batik tie-dyed product categories of clothing agree with table cloth products from Batik tie-dyed cotton fabric with waterproof finishes and selected to buy after this product launch to market from personal preference reason. Color and design price appearance and special properties are the reasons to choose. The total satisfaction to products was highly satisfied (mean 3.65).
การพัฒนาบอร์ดไมโครคอนโทรลเลอร์เพื่อใช้ตรวจสอบระดับปริมาตร น้ำบาดาล
Water became an important factor for propelling production process of any industries or factories and groundwater was option for production cost reduction especially in areas where had no surfacewater. B.Foods Product International Company Limited an affiliate of Betagro Group was located in Lop Buri Province to daily consume huge quantity of groundwater for production process in its factory. Measuring and recording levels of groundwater in 2 ground tanks related to volume of the water at time point of every 3 hours must continually be done every day in order to prevent lack of water fed into the factory that may impact of its production process. The main problem was caused of unexpected non-working of pumps. Knowing fluctuation of water levels could provide their immediate improvement and recover to avoid serious impacts. A microcontroller board could be employed to control groundwater volume in order that the company could closely follow up levels of groundwater in the ground tanks in real time and continuity. This study went on designing the microcontroller board for managing utility system and maintenance by using with level meter and wireless receiver and transmitter for testing working efficiency every 3 hours of each everyday during 1 February 2016 till 11 March 2016 totally 40 days. It was compared with those of same duration done manually. The findings revealed that the figured from 2 methods became similar and had very close relationship with each other. This could indicate that the simulated microcontroller board could be employed to automatically control groundwater volume efficiently. The company could bring it to appropriately trace levels of groundwater in the tanks in accordance with water usage behavior in each period of time for disruption of production process caused of insufficient quantity of groundwater. And this could be adaptable benefits for improvement of any organizations and also for any further studies

Objectives of this study were to design and develop seamless womens wear using pattern techniques and to study customers satisfaction of seamless womens wear using pattern techniques. The researcher designed 5 categories of womens wear coat blouse dress skirt and pants. Proper designs for sewing prototypes were selected by experts. These were made from three types of fabrics light medium and heavy. Customers satisfaction survey was made from 385 women working in private companies in Bang Rak Bang Kapi and Pathum Wan Districts of Bangkok. Accidental sampling of participants were asked to answer questionnaires. Data was analyzed by using packaged computer program. Statistics used were frequencies percentages means and standard deviations. The results showed that the majority of samples were aged between 26-30 years educational levels were bachelors degrees monthly income was between 15001-25000 Bahts never bought or used seamless womens wear consideration in buying was by preference bought every month at prices between 501-1000 Bahts per item. The overall customers satisfaction to seamless womens wear was at a very satisfied level at the mean of 4.12.
