ABSTRACT
The number of students using online educational systems is increasing, especially after the growth of the use of this type of system due to the social isolation caused by the Covid-19 pandemic. This situation highlighted the challenge of analyzing the users' experience in this type of system, especially when evaluating more complex experiences, such as the flow experience. One of the most promising innovative alternatives is to use the behavior data logs produced by students in educational systems to analyze their experiences. In this paper, we conducted a study (N = 24) to analyze the relationships between the behavior data logs produced by students when using a gamified educational system and their flow experience during the system usage. Our results contribute to the automatic users' experience analysis in educational systems. © 2022 IEEE Computer Society. All rights reserved.
ABSTRACT
Wearing facemasks, face shields and social distancing are some of health protocols that are being imposed to lessen the risk of viral transmission specifically COVID 19. All establishments here in the Philippines build their own sanitation booths to ensure virus prevention. This study aims to address the issues regarding the use of chemical disinfectants and manually placing them in sanitation booths, and the ineffective manual ways of sanitizing individuals. This study is a design project adopting the developmental type of research method. Hypochlorous acid (HOCL) has a lot of potential as a disinfectant. In an electrolysis chamber with dilute salt and distilled water, HOCL can be made. The researchers design a device to automate the manufacturing of HOCL, which will be use as disinfectant, and automatically sanitize individuals with a safer and non-toxic disinfectant. The researchers prepared questionnaires to assess the acceptability of the device. The statistical tool used in the interpretation of data is weighted arithmetic mean. The major finding of this study is the ability of the device to convert distilled water and salt into disinfectant solution with the electrolysis process utilized, the duration of the process that will optimally convert it is 40 minutes, with accurate reading of analog pH sensor and lessen the exposure to each individual through the automation of the sanitation booth. For that reason, the researchers conclude that this design project provides a way to ensure virus prevention using automatic sanitation booth with disinfectant (HOCL) solution that offers more benefits over traditional sanitation methods. The overall acceptability rating of the design project is 4.46, interpreted as Very Good which shows that the device has high satisfaction. © 2021 IEEE.
