In India more than 34.5 lakh tonnes of plastic waste is generated, out of which plastic in the form of polypropylene is the second biggest contributor (19%) accumulating to 6.55 lakh tonnes [7], also it takes thousands of years to decompose in landfills. Fly ash, a by-product in coal-fired power units, can lead to air pollution if scattered unattended on the ground and if dumped at landfill, It would lead to toxic elements getting discharged into groundwater. More than 217.02 million tons of fly-ash was formulated of which 49.92 million tons was dumped in landfill.[12] India being a developing nation is expected to generate more than the above-mentioned plastic waste and fly ash to sustain rapid urbanization and economic growth. Hence, the purpose of this study was to look at the possibility of utilizing reprocessed polypropylene, used foundry sand and fly ash as a binding substance in the manufacturing of paver blocks. To be applied in pedestrian pathways, parking lots, gardens and less to moderate traffic volume roads. A combined method of heating and compression was implemented for full scale casting. The polypropylene pellets are melted and mixed with used foundry sand and fly ash in numerous proportions to determine the optimal proportion. Compressive strength &amp; water absorption test was conducted on the specimen.</p> G.Mishra*, P.Mahale, A.Yadav, S.Meshram, P.Singh, S.Kewate, P.Shivrajsinh & A.Singh (Author) Copyright (c) 2023 http://ytgcxb.periodicales.com/index.php/CJGE/article/view/319 Tue, 05 Sep 2023 00:00:00 +0000 Factors affecting the application of food ordering technology by customers in Ho Chi Minh City, Vietnam http://ytgcxb.periodicales.com/index.php/CJGE/article/view/321 <p>Benefits of physical delivery products have stimulated the increasing demand for this service.

Translating messages between Japanese and Vietnamese, however, presents significant challenges due to the languages' complexity and uniqueness. This article explores the issues in Japanese-Vietnamese translation and the benefits of popular translation software. The complexity of Japanese-Vietnamese translation stems from cultural differences, writing systems, grammar structures, and rich vocabulary. These differences hinder the accurate and coherent conveyance of the original content. Fortunately, popular translation software has become prevalent and effective. Tools like Google Translate and Bing Translator utilize artificial intelligence and machine learning to enhance translation capabilities, providing faster and more accurate results. The benefits of using such software are evident. It saves time and effort for translators, allowing them to focus on refining translations for accuracy. Minimizing human errors, increases the reliability of translated content. Moreover, it fosters cultural exchange and collaboration between Japan and Vietnam. Despite its advantages, translation software cannot replace human translators entirely. Creativity, cultural knowledge, and deep understanding are crucial for accurate and impactful translations. Combining technology with human expertise produces the best results in Japanese-Vietnamese translation. As cross-cultural communication continues to expand, the application of popular translation software, complemented by human insight, remains vital for effective and meaningful communication between these languages.</p> Vo Quoc Huy (Author) Copyright (c) 2023 http://ytgcxb.periodicales.com/index.php/CJGE/article/view/322 Thu, 07 Sep 2023 00:00:00 +0000 Digital marketing applications to personalize the user experience during digital transformation in Vietnam http://ytgcxb.periodicales.com/index.php/CJGE/article/view/323 <p>Today, when the world and the market are undergoing drastic changes, digital transformation in businesses is inevitable. This process applies to both B2B and B2C, as consumer behavior, knowledge, expectations, and processes are constantly changing. A business can go digital for many reasons, but by far the main reason is that it's a matter of survival. Before the COVID-19 pandemic, an organization's ability to flexibly adapt to difficulties in supply chain disruptions, market pressures, and customer expectations was very important. The goal of business digital transformation is survival and future strength, but digital transformation initiatives have brought many other benefits to businesses. Currently, increasing customer experience has become an important and competitive factor in the business environment. Here are some reasons why increasing the customer experience is important: In a competitive market, improving the customer experience helps businesses set themselves apart from the competition. Customers often prioritize choosing the best and most memorable experiences, and this can help businesses attract and retain customers. A good experience builds trust and loyalty among customers. When customers are satisfied with a business' products, services, and experience, they are more likely to continue shopping and interacting with that business in the future. This helps to create a loyal and sustainable customer community.</p> Nguyen Thi Ngoc Linh (Author) Copyright (c) 2023 http://ytgcxb.periodicales.com/index.php/CJGE/article/view/323 Sun, 10 Sep 2023 00:00:00 +0000 Effect of video games on academic performance of university students’ assessment and appropriate solutions http://ytgcxb.periodicales.com/index.php/CJGE/article/view/324 <p>Video games are inherently a useful means of relieving stress, but many people have used them negatively. Game addiction is extremely stressful. Many teenagers sit in front of a phone or computer screen all day, to the point that they forget to eat or sleep. The image of the gates of Internet shops packed with student bicycles is no longer rare. Many young people spend more time playing games than reading, studying, or participating in extracurricular activities. The cause of this situation stems directly from human consciousness. The students are still young, not aware enough of the harmful effects of the game, do not know how to manage their time, and are easily manipulated and enticed. In addition, the neglect of management by family and school is also a factor leading to the above phenomenon. In the long run, toxic video games will wreak havoc both physically and mentally. Addicts' health will deteriorate, their behavior will become sluggish, and their thinking will become clouded. Since then, students will be distracted from studying, alienated from people around them, and have severely degraded personalities. To put an end to this situation, each person must know how to adjust themselves, using games as entertainment tools in moderation.</p> Le Pham Duc Truong (Author) Copyright (c) 2023 http://ytgcxb.periodicales.com/index.php/CJGE/article/view/324 Sun, 10 Sep 2023 00:00:00 +0000 Challenging use of Fatty Acid Methyl Ester (FAME) as an additive into diverse applications http://ytgcxb.periodicales.com/index.php/CJGE/article/view/325 <p>The trends observed in those studies regarding the utilize of Fatty Acid Methyl Esters (FAME), FAME derived from vegetable oil have been explored in numerous studies for their potential to enhance the lubricity of diesel fuels in diesel engines.
