A Study on the Effect of Participating in Tutorial Courses on Happiness During the Summer Break of Thai High School Students in Bangkok

/in /by

During the semester break of high school years, one of the most common activities of students is taking tutorial courses, as most students consider this interval to be the preparation time for entering their dream school. The attitude of each student toward tutorial courses is very different; some are very happy to attend, while others are not happy at all. Happiness plays an essential role in high school students’ lives during the summer break since happiness helps students relax and also increases their productivity. Thus, we are curious about the effect of tutorial courses on the happiness of Thai high school students in Bangkok. In order to determine the correlation between these two factors, we decided to conduct a cross-sectional survey. The data was collected by sending questionnaires about the effect of participation in tutorial courses on happiness to students in various high schools in Bangkok. We received a total of 324 respondents, who are from various types of high schools, including public, private, international, and home schools. Statistical Product and Service Solutions (SPSS) was used for data analysis. The results show no significant relationship between tutorial courses and happiness, which include: 1) the number of tutoring hours taken per day (P-value = 0.342), 2) the duration of the semester breaks (P-value = 0.727), 3) the number of days to take tutorial courses in a week (P-value = 0.319), and 4) the type of tutorial courses taken (P-value = 0.221). This research has most of the respondents studying in public schools and studying in grade 12, so this might be the reason that extra tutorial classes do not affect happiness. This research helps us understand whether there is a relationship between happiness and taking tutorial courses during summer break, and also provides us with information for further research.

Improving a Two-Way Interaction Customer Service Platform in Company X using AHP

/in /by

The Covid-19 Pandemic has accelerated mass digitalization in most human activities, including in the construction industry. As a response to the social restriction policy during the pandemic, customers and companies have preferred doing business online. Company X has already launched an online customer service platform that could be maximally used during the social restriction policy. This platform uses SST (Self-Service Technology) to let customers perform their service independently. However, the platform was ineffectively utilized due to a lack of sense of two-way interaction. The stakeholders suggested adding a new feature based on the customer’s aspirations and the company’s considerations. During the development, understanding the relationship between the user and the system must be learned through HCI (Human-Computer Interaction). This research is primarily focused on the factors that affect layout design. The method to obtain a new feature in this customer service platform is using Analytical Hierarchy Process (AHP) to minimize inconsistencies while considering the new features.

Nootropic Activity of Ethanolic Extract of Zingiber officinale and Centella asiatica on Stress Induced Rats

/in /by

Nootropics, natural or synthetic substances that boost brain function and cognitive abilities, were investigated in this study. Specifically, the effects of Zingiber officinale and Centella asiatica extracts were compared to the standard nootropic piracetam. Both plant extracts demonstrated nootropic activity and contained phytochemicals like flavonoids, tannins, and saponins that protect the brain from oxidative damage. Sterols such as stigmasterol inhibiting acetyl CoA esterase activity were also present. Tests were conducted on rats given the extracts or piracetam daily for 7 to 21 days. High and low doses were used. Nootropic effects were measured using elevated plus maze and Morris water maze tests compared to controls. The results were promising: At higher doses, the extracts significantly reduced latency time to 21 ± 0.33 seconds compared to 33.33 ± 0.12 seconds for piracetam and 54 ± 0.08 seconds for controls. This suggests the plant extracts have considerable nootropic potential when administered at higher doses.
