Workings portfolio design home decoration method 1 small put of box can adjust the size between channels. Method 2 box put of large removable foldable and Method 3 small table of lamp removable foldable. 2. Target groups choose the design of home decor in the 3 approach. 3. The target audience is satisfied with the new home decor more than the original in all sides. Statistically significant at the .05 level dealers are more satisfied than the original model in almost every aspect. Except for eco-friendly images and the new home decor is more effective than the old one.

The purposes of the research were to 1) study the attributes of the graduates according to standards of learning outcome 2) study the 21st century skills of English for International Communication graduates desired by employers 3) compare the attributes of the graduates according to standards of learning outcome categorized by the individual factors and 4) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The population were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews which were analyzed by the SPSS program. The statistical data analysis was performed by frequency percentage mean standard deviation and Fdistribution and the interview data analysis was performed by frequency and content analysis. The results were found as follows. 1. As for the employers information33emoloyets were from private and service businesses (60%) and 14 employets were from government sectors (25.50%).As for the working statuses29 employers were the officers (53.70%) 20 employer were the supervisors (37.00%) and 5 employers weie mangers (9.30%) 2. The overall requirement of hte employers for the attrbutes of the graduates according to standandards of learning outcome was at the high level (=4.48). As for each attribute morals and ethcs were the most desirable (=4.75) the second highest level was interpersonal skils and accountabiliy (4.57) and the last one was the intellectual skills (=4.25) 3. The overall requirement of the ernptoyers for the 21st century skills of the graduates was at the high level (=4.43). As for each attribute the highest level was enthusiasm collaboration and thinking skills respectivrty (=4.634.58 and 4.54) The lowest tevel was the inquiry skills (=4.07). 4.The results of the research hypothesis were; 4.1 There was a significant difference between the employers with different employrment sectors (government and service business sectors) and the requirement of the graduates attributes. There was no significant difference between the employers with different working status and the requirement of the graduates attributes. 4.2 There is no significant difference between the employers with diferent employent sectors and working status and the requirement of the graduates attributes.

Molds manufacturing to produce chloroprene rubber product with carbon steel over time the mold surface will wear. From the original. The practice in the industry often uses surface coatings (Hard chrome method) or change materials to create molds. Therefore this research is to study the effect of corrosion or wear. To see the size of surface mold changed in the experiment. Based on a tolerance of 0.1 millimeters at the molding point and after molding in the actual work conditions of a 2-3 weeks sample and mold size measurement. At less than 10 times the permissible coordinate value is 0.01 millimeters. The experiment found that. The wear of carbon steel molds was formed with chloroprene rubber. It has a very small value when referenced to the tolerance coordinates which is not significantly reduced when the rubber specimen size is determined. The allowance range is 10 μm to 100 μm. Therefore the design of chloroprene rubber to make molds with carbon steel. It can help reduce production costs. Without replacing with corrosion-resistant materials or adding coatings.

This paper presents the simulation and experimental result of class-E power amplifier. It is often used in designing a high frequency ac power source because its ability to perform the conversion efficiently even at high frequencies with significant reduction of switching losses. This paper aims to compare the transmission performance of electrical power between the air core transformer and iron core transformer which the identical input voltage of 50 VAC. Both transformers are designed to step voltage up (step up transformer) ratio of 1:4.5. The Arduino microcontroller Arduino was used to generate a pulse width modulation (PWM) with operating frequency of 3.74 kHz. IC gate drive TC4422 was used to drive the IRF510 MOSFET. Based on the simulation and experimental results the power loss in air core transformer is 75 percent while power loss in iron core transformer is 0.2 percent. The maximum distance that can transmit electric power of air core transformer is 9.3 centimeters.
