The objective of this research was to study information behavior in digital environment of students from Rajamangala University of Technology Phra Nakhon. The sample was 387 undergraduate students from Rajamangala University of Technology Phra Nakhon in the academic year 2019. The research tool was a questionnaire. The results of the research were that the students aimed to find supplementary information for extra work do report and research or project respectively. Students had the process of searching for information in the following order : specify the topic; select or organize the information; survey information and resources; search information link and follow up with new information. Most information behavior of students was searching from the websites such as Google Yahoo and using link points on search engines like Google Yahoo etc. Method for assessing information that students used the most was complete content and reliable information. Method for keeping track of information that students used the most was from social media such as Weblog Facebook YouTube. The information format that students used the most were pictures. And the action after obtaining the information that students used the most was validation and completeness of the content.

The study on credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon were aimed to investigate1) personal factors of support staffs at Rajamangala University of Technology Phra Nakhon 2) credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon and 3)The relationship between personal factors and credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon. The instrument used to collect data was a questionnaire; and the sample group in the study was 260support staffs working at Rajamangala University of Technology Phra Nakhon. To analyze data descriptive statistics including frequency percentages and cross-tabulation distributions were applied. The hypotheses were that personal factors were related with credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon. The results revealed that the support staffs at Rajamangala University of Technology Phra Nakhon were between 30 to 39 years old. They held bachelors degrees and worked as the university employees. They were single who earned total income per month of 20001 - 30000 baht. There were 2 - 3 members in the family and had been working for over 5 years. Most of support staffs at Rajamangala University of Technology Phra Nakhon had 1- 2 credit cards with the duration of 2-3 years. The credit card limit was 20000 - 39999 baht. The type of the credit card was Visa card and the amount of monthly credit card spending was 2001 - 5000 baht. Regular cards used were issued by Krung Thai Bank (KTC). The value of goods or services for each spending was 1001 - 3000 baht at the most. Types of products or services that credit cards were used regularly were daily life products. The reason for using a credit card was its convenience for paying for goods or services (cash carried reduction). The channels to receive news that attracted applicants for credit cards were from bank employees and the opportunity to use credit cards to receive reward points to redeem discounts and prizes. Channels of spending via credit cards were through automatic credit approval machines with the frequency of spending of 1 - 3 times per month to pay for goods and services and installment payment for products and services on a periodic basis. The hypothesis test results disclosed that personal factors of the support staffs of Rajamangala University of Technology Phra Nakhon had a relationship with credit card usage behavior the bank cards regularly used the value of goods or services for each use and the opportunity to use credit cards.

The objective of this research is to study the combustion behavior of a gas-saving burner S-10 using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. LPG pressure of 4 psi was released for this study. The combustion behavior was shown in temperature contour and velocity vector. The CFD results were verified by measuring the temperature around the burner head with a vessel. From the study it was found that the CFD’s results of flow velocity and combustion temperature distributions were validated with the experimental values. The CFD’s result errors were less than 10.35% and 11.87% comparing with the velocity and temperature measurement respectively. The fluid flow and combustion behaviors can be described by this CFD model. Moreover the CFD model of the gas-saving burner S-10 can be applied to improve the thermal efficiency of the burner in the future.
