The objectives of this research is to study the relationship between tolerance and measurement range of load cells. Tolerance test kit length of mass beam 90 cm was used. It can create the compressed force at the load cell more than 1 kN. The experiment cam be divided into 2 stages; 1.) verification of load range and 2.) linearity test. Both stages are tested at a temperature at 25°C using 10 to 30 kg of mass in the lowest compressed force condition of 0.091 kN and the maximum compressed force condition of 1.12kN As a result the linearity performance of the tolerance of the load cell test kit between calculated force and displayed value force are different 0.354 percentage only while the standard deviation of displayed value force and voltage signal output are 0.0013 and 0.0022 respectively. It reveals that the experimental result is reliable because of less than 1. In addition the tolerance of the load cell tolerance testing machine is 0.00300 (0.3 percent) which was calculated from the comparison of the tolerance specification of two main equipment that specified by manufacturer.

This research aims to develop the guidelines of an automated educational recommending system through various social media in form of chat robots (Chatbot). This is under the assumption that the Chatbot can assist the human workload in responding to Students’ frequently asked questions (FAQ). With the Chatbot inquirer students would be responded in fast and accurate to the inquiries. The prototype of this system is built on the Dialogflow platform to connect to the Line Application. The prototype was tested via users and received “good” level of the overall user’s satisfaction.

The data obtained from the in-depth interview were transcribed and analyzed by using textual analysis. Most participants in this study were female university students whose age group was 19 years old. The participants filled in their answers from 1 to 5 that is 5 strongly agree 4 agree 3 neutral 2 disagree and 1 strongly disagree to report their attitudes towards the freshman welcoming activities organized in the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon.

The students mostly agreed with positive effects of participating these kinds of activities: building relationship unity and responsibility. However they also moderately agreed that these activities could provide negative effectives: individual and organizational damage (for example losing publica image) According to the descriptive analysis and textual analysis the results showed that these university students were willing to take part in freshman welcome activities indicating that the activities were suitable supervised by related departments. They also suggested that there should be welcome activities based on their interests and suggestion box to achieve the goal. However one of the limitations of the study was the widespread of coronavirus resulting in the average score and standard deviation in some questionnaire items.
