The study was conducted to explore organizational factors influencing perceptions of Of Rajamangala University of Technology Phra Nakhon mission.This research is quantitative research which its 287samples used were Rajamangala University of Technology Phra Nakhon personnel selected through proportional stratified random sampling. The data collected were analyzed by frequency percentage mean standard deviation Pearson Product Moment Correlation Coefficient and multiple regression equations. The research results revealed that the organizational factors affecting perceived mission of Rajamangala University of Technology Phra Nakhon personnel included factors such as 1) strategic aspect 2) system aspect 3) Staff aspect 4) Style aspect and 5) skill aspect which influenced the perception of the mission of Rajamangala University of Technology Phra Nakhon staffs at 0.05 level of statistical significance. This could be explained jointly by the mission statement in the overall at 66.2 percent. However the organizational aspect and value aspect had no influence on the perceived mission of Rajamangala University of Technology Phra Nakhon staffs.

The purposes of the study were to study 1) the demographic characteristics 2) the level of the marketing mix factors that affect food consumption behaviors 3) the level of knowledge about nutrition 4) the food consumption behaviors and 5) the relationship between factors that affect food consumption behaviors and food consumption behaviors. The subjects were 159 non – commissioned officers under royal aide de camp department who worked for a year in 2015. To collect data the research instrument wasquestionnaire. The statistics used to analyze the data were frequency percentage mean standard deviation and chi-square. The data analyzed by SPSS. The research found that 1) the most respondents were mostly female age range in 31 - 40 years married graduated Bachelors degree Sergeant major 1st class/Chief petty officer 1st class/Flight sergeant 1st class the average income of between 20001 - 30000 baht per monththere were members of the family 3 - 4 people and domiciled in Bangkok and Suburbs 2) thequality of the food’s average score were the highest score3) the respondents generally haveknowledge of nutrition in the very good level 4) the respondents mostly eat fresh food buyingfood 3 - 4 times per week and 5 - 6 times per week eating 3 meals a day buying fooddaily buying food in the evening the average expense is between 51 - 100 baht buying foodfrom markets and restaurants regardless of their own to buy food deciding to buy food for goodhealth and 5) the number of family members related to the average expense per time in buyingfood the source of buying food the person who influences on buying food and the factorsaffecting the decision to buy food. While the level of education correlated with place of buying food.In addition the rank correlated with the average in buying food at a time. Besides average monthly income is related to the day to buy. Moreover the hometown is associated with the number of meals eaten per day. Similary the status is related to the average expense per time in buying food. The food quality related to the person who influences on buying food and the deciding factor in buying food. And the knowledge about nutrition related to the period to buy food and place of buying food. At the Statistical significance level of .05.

Electricity Generating Authority of Thailand (EGAT) encountered problems voltage swell from the changes of power system configuration high-voltage 115 kV substation name Lopburi2 to radial. Control Center closed capacitor bank caused the steel industry electric power plants and renewable energy solar tripped themselves out. As a result EGAT loosed of power produced of solar power plants. It also affected confidence in the systems power consumption. EGAT’s necessary to learn from this event. This research was simulation power system modeling of “High Voltage Substation Lopburi2” and grid connection both the system EGAT and PEA with EMTDC-PSCAD for analysis of the voltage swell caused by close capacitor bank at “Lopburi2” substation compared with actual events then calculated the voltage swell occurred at high voltage station linkage. Finally this research presents a method of reduction of their impact of close capacitor bank at “Loburi2” to avoid the voltage swell in the future.

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.

The purposes of this special project were to media production for infographic of Admission System of the Faculty of Mass Communication Technology Rajamangala University of Technology Phra Nakhon and study the satisfaction to infographic of Admission System of the Faculty of Mass Communication Technology Rajamangala University of Technology Phra Nakhon by using the tool was online questionnaire to study the satisfaction of the general public towards infographic with 100 samples. Data analysis are frequency mean and standard deviation. Major findings were as followed: The mean score of content satisfaction were highly satisfied (𝑥̅=4.58). The mean score of presentation satisfaction were highly satisfied (𝑥̅=4.52).
