The research utilizes an online survey method with<br>102 participating students, thereby analyzing both subjective factors (awareness, attitude,<br>motivation) and objective factors (social environment, living conditions) that influence social<br>media usage behavior. The results indicate that students primarily use social media for<br>communication and entertainment rather than for academic purposes. Additionally, excessive<br>social media usage may lead to negative consequences such as decreased concentration, adverse<br>effects on mental health, and reduced academic performance. The main objective is to clarify the<br>positive and negative impacts of social media, particularly from popular platforms like Facebook,<br>Zalo, Google, and YouTube, on students' habits and behaviors, thereby helping students use social<br>media more effectively and maintain better balance in their lives.</span> </p> Thi Lan Anh Tran , Van Manh Nguyen Copyright (c) 2025 Tạp chí Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/262 Tue, 01 Oct 2024 00:00:00 +0700 Effective Games for Teaching and Learning the Simple Past Tense https://jst.bdu.edu.vn/index.php/jst/article/view/263 <p><span class="fontstyle0">Việc dạy và học ngữ pháp tiếng Anh một cách hiệu quả không phải là điều dễ<br>dàng đối với cả người dạy và người học, đặc biệt là khi học các thì tiếng Anh.

C. hystrix is a type of Citrus<br>fruit with a high content of phenolic compounds. Fruit peels have been reported to exhibit<br>higher antioxidant content than the edible part. Therefore, C. hystrix peel was selected in this<br>study. This work investigated the effect of solvent polarity (hexane, ethyl acetate, and nbutanol) employed during the fractionation of ethanolic crude extract and determined the total<br>polyphenol content in fractionated extracts. Using specific chemical reactions to characterize<br>the chemical composition of C. hystrix fruit peel extract. The total polyphenol content in the<br>fractionated extracts was determined by measuring the absorbance of the extract with the<br>standard of gallic acid. The results show that all the ethanol extracts of C. hystrix peel included<br>polyphenols, flavonoids, coumarins, tannins, and reducing agents. The total polyphenol content<br>in young C. hystrix peel is the highest, with a content of 0,337 mg/g. Besides, the total<br>polyphenol content in ethyl acetate extract (0,128 mg/g) is higher than in n-hexane (0,016<br>mg/g), n-butanol (0,084 mg/g) and water (0,039 mg/g). This result is the first report on the<br>phenolic compounds in C. hystrix peel extracts at three stages of fruit growth. It can be helpful<br>to scientific data for application in the pharmaceutical industry and other fields in our lives.</span> </p> Van Ut Le , Thi Huynh Giang Nguyen , Thi Hong Phan Nguyen , Huyen Tran Tran Copyright (c) 2025 Tạp chí Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/266 Tue, 01 Oct 2024 00:00:00 +0700 Formulation and evaluation of hard capsule containing Houttuynia cordata extract https://jst.bdu.edu.vn/index.php/jst/article/view/267 <p><span class="fontstyle0">Houttuynia cordata, a medicinal herb with several health benefits, which is<br>widely used for the treatment of hemorrhoid.

Among these, prescribing errors (PE) are mistakes<br>related to the selection of medications, such as incorrect indications, contraindications,<br>allergy history, contraindications with ongoing treatments, and other factors. These errors<br>can lead to increased side effects, reduced treatment efficacy, prolonged treatment duration,<br>and higher healthcare costs for patients. Such incidents are associated with pressure on<br>healthcare services and significant healthcare costs.

This study analyzes various theoretical frameworks and definitions of the<br>digital economy while synthesizing measurement experiences from countries such as<br>China, the United States, and Europe. Differences in measurement approaches have led to<br>inconsistent evaluations of the digital economy’s scale. Based on international experiences,<br>the study proposes a digital economy development framework for Vietnam, consisting of<br>three main components: ICT-based digital economy, Internet and platform-based digital<br>economy, and sector-specific digital economy.

When today's logistics applications tend to be more positive<br>and environmentally friendly, performance is also significantly improved in the system.
