The study was undertaken to compare the lead accumulation and removal of Dracaena sanderiana, Dracaena reflexa, and Dracaena deremensis on artificial lead solutions to apply plants in lead pollution treatment. The experiment consisted of 6 treatments corresponding to 3 investigated species of Dracaena. Each treatment was grown on 2 types of solution with Pb and without Pb used as control. The results indicated that the growth of D. sanderiana, D. reflexa, and D. deremensis was not affected at Pb concentrations of 100 ppm. All three plant species had the ability to absorb and accumulate Pb. In which D. sanderiana was a typical lead excluder because the lead concentration in roots (1952.14 mg/kg), shoots (221.78 mg/kg), and leaves (166.46 mg/kg) of the plants were the highest among the three plants tested. The most of lead accumulated in the root, and transportation of lead in D. sanderiana, D. reflexa, and D. deremensis from root to shoot was restricted. Besides, the highest % removal of Pb was found at D. sanderiana (93.16%) and the minimum of 66.77% at D. reflexa. D. sanderiana is the best choice among the three Dracaena species used for phytoremediation of lead contaminated wastewater.

The patriotic activities of teachers, students, and pupils in the temporarily occupied regions of Long An – Kien Tuong were a particularly important part of the open political struggle on enemy territory during the resistance against the United States. Immediately after the 1954 Geneva Agreement, many schools in Long An – Kien Tuong established revolutionary bases. Some teachers mobilized colleagues, students, and the public to fight against anti-communist activities, forced conscription, and to demand civil rights and democracy. In subsequent years, Long An – Kien Tuong became the site of numerous diverse and creative struggles (rallies, demonstrations, leafleting, journalism, cultural activities...), attracting the participation of many educators and students. Some teachers and students actively participated in armed and covert operations, displaying many heroic acts of combat and sacrifice. Alongside activities in liberated areas, the struggle of teachers and students in the temporarily occupied regions of Long An – Kien Tuong contributed distinctive values, enhancing the illustrious history and tradition of Long An province's education sector today.

Abstract Cultural relations between Vietnam and China, of course, need no further assertions. But this process of cultural relations, then requires further studies to see the diversity of this cultural relationship. We, in this report, present the cultural relationship between Vietnam and China through poems written on the topic of Zen - Buddhist on the way to the mission of Vietnamese ambassadors in the last 18th century and early 19th century, in three main aspects: the reception of the Buddhist cultural space, the sense of meditation in front of the temple, and the intimacy between the envoyers and the Zen masters and officials of the North. From there, we hope to contribute an additional perspective on the Vietnamese people's position - the same level position, in the cultural exchange between Vietnam and China. Keywords: Cultural relations, Enyoy poetry, Envoyer, Vietnam - China, Zen - Buddhist.

This article presents how to speculate, design and simulate a mechanical horse based on the point of view of the military man Khong Minh, a talented character in the work "Three Kingdoms" (author La Quan Trung). The behavior of this type of horse closely resembles that of a real horse. That is, it can walk, run, carry goods or people. It is made mainly of wood or steel. The authors speculated that Khong Minh placed a leaf spring in the belly of the mechanical horse. Soldiers just need to rotate so that the leaf spring twists, it will store energy in the form of potential energy. Then, it slowly unfolds, and the potential energy is converted into kinetic energy, transmitting motion to the mechanisms connected to the horse's legs. Finally, the mechanical horse lifted his leg and was able to walk. Despite such speculation, when recreating a mechanical horse, our team of authors used a battery-powered motor instead of leaf springs and gear transmissions as a pre-assembled transmission part in the belly of the mechanical horse. We design additional parts such as the head, tail, belly, legs, etc. to create a complete mechanical horse. The design goal of the author's mechanical horse is to clear people's doubts about the "wooden buffalo mechanical horse" in the literary work "Three Kingdoms". At the same time, this type of mechanical horse is also applied as an amusement ride for people in tourist areas and as a children's toy in the family.

The issue of marine pollution in general, as well as pollution brought on by oil spills into the sea, in rivers and lakes, or wastewater from factories, businesses, mechanical repair shops, gas stations, universities, and auto repair shops, is one that the world is currently facing, particularly since when it does, it invariably results in harm to the environment and people. Oil spills result in oil plaques on the ground, in rock crevices, washed up on the coast, a foul smell, a loss of tourism beauty, harm to the ocean's ecosystem, and even equipment damage. equipment, supplies, water transportation, etc. We had to use very expensive oil spill blotting papers at the time. The amount of hair that individuals discard each day is not little, and even when it is burned, it emits unpleasant scents and polluting gases that are harmful to human health. Furthermore, it is very easy to make a hair mat at vehicle wash facilities, school restaurants with big parking lots, and car repair shops. To prevent the majority of the oil from being spilled into the environment, handmade oil-absorbing carpets made of hair materials are laid over the drains in these locations.

Vietnam's economy is operated to serve more than ninety million people so this is a very vivid picture. The large population brings many advantages to the food production sector in general and the production of fresh noodles in particular. Fresh vermicelli is the raw material for processing many dishes of the Vietnamese people for a long time, that's why there are many Vietnamese dishes with indispensable ingredients, which as Noodles in the national culinary books. Vietnam. The production of fresh vermicelli with the main ingredient is fermented and shaped rice with simple steps, but hidden inside there are environmental issues that need to be considered. The production and business associated with environmental protection are the responsibility of most enterprises and production facilities in Vietnam. The fresh noodle food production industry is no exception. Instead of learning about the aspects that affect the environment in the traditional way of collecting information, analyzing, and evaluating the current situation, this time the research team looked at understanding the causes of environmental pollution in terms of consumption. ISO 14001 international standard. ISO 14001 Environmental Management System is an international standard that helps businesses and establishments identify the important role of the environment as well as the risks brought by the environment, thereby realizing the environment as an activity of the Organization. In this standard, the commitment to prevent environmental pollution is a mandatory condition, so determining the environmental aspects to overcome the impacts is a key element of the standard. If a business achieves ISO 14001 Certification, it will have a very good effect in promoting the corporate image of being responsible for the environment and the community.

Culture plays an important role in shaping the perceptions, beliefs, and experiences of refugees as they navigate decisions and actions in a new society. Based on an analysis of 88 oral history interviews conducted by the Vietnamese American Heritage Foundation (VAHF) with Vietnamese refugees in the US after the war, this paper examines the relationship between culture and social integration, particularly the cultural values that Vietnamese refugees have chosen and promoted to help them adapt quickly and successfully in the new society. Using a thematic analysis method, cultural values such as self-effort, a studious tradition, sacrifice, and intergenerational responsibility help Vietnamese refugees improve their socio-economic status after a period of settlement in the U.S. The stories specifically illustrate how Vietnamese people have applied cultural values to social integration strategies, establishing connections between culture and economic opportunities within the socio-economic conditions of the United States.

The relationship between language and gender is an interesting topic which has been under discussion over the last few centuries. Throughout the history of language study, lots of studies have been conducted and different linguists have been looking at this issue from different angles. As a socially constructed notion of what is feminine and what is masculine, gender is considered to be closely interrelated to different aspects of our life, especially to our language. From interdisciplinary perspectives with the corpus being the language used in daily communication, the study pointed out various differences between genders both in language use and in aspects of the language used to talk about each gender. From these differences, the study can help us understand a great deal of American culture which, in turns, makes it easy for us to use the language effectively.

FACTORS AFFECTING ENGLISH SCORES AT NATIONAL HIGH SCHOOL EXAM OF SOPHOMORES AT THU DAU MOT UNIVERSITY: EMPIRICAL EVIDENCES FROM GLS METHOD

Binh Duong, a dynamic province in the Southern Key Economic Region in Vietnam, has a fast growing economy and strong economic restructuring towards industrialization and modernization, have affected many aspects of economy, culture, society and environment. This study analyzes the influence of economic restructuring on urban development in Binh Duong province by utilizing the time series data throughout 2000 - 2020 and the household interview method of the topic "Urbanization and its effects on land use restructuring in Binh Duong province" shows the shift of occupations from agriculture to non-agriculture. The research results show that economic restructuring contributes to promoting economic and social development in general and expanding the urban network of Binh Duong province in particular, but it has some limitations in the process of development. Therefore, Binh Duong wants to successfully integrate into the world economy and develop urban areas towards sustainability (by 2030), it must have specific, scientific and objective analysis and evaluation on the success and limitations of the economic restructuring process and its impact on the urban system in recent times. The research results also have a scientific basis for proposing appropriate and effective solutions and policies to successfully implement the goals and orientations of economic restructuring and urban development that Binh Duong has been approved.

This paper aims to identify the English-learning motivation of Thu Dau Mot University’s students. Based on the questionnaire, the data for analysis were collected from more than 100 students of different majors studying non-majored English at Thu Dau Mot University’s Foreign Language Center. The findings show that students have relatively positive learning motivation. In the relationship between learning achievement and motivation, the motive that comes from the students’ desire to get a better job occupies 58.4% of all the students surveyed because they believe it is essential and decisive to ensure their future income (applying for a job to earn money), and motivation to integrate into modern world life (because English is a global language: 40.4%) are the factors affecting students’ achievement.

In this work, we focus on investigating ill-posed problems (according to the definition given by Hadamard) in the topic of its application. Specifically, we present some theories about the properties of the ill-posed problem in image processing. By using discrete Fourier transform and fast Fourier transform methods, we present several results on image processing topic. Finally, some illustrative examples are presented through algorithms running on Python software.

In the current work, we study a Cauchy problem for a time-fractional pseudo-parabolic equation with a globally Lipschitz source term. We prove the unique existence of a mild solution to the problem, by the common Banach fixed point theorem. This solution is then verified that exists globally in time by Gr¨onwall’s inequality. Compare to previous works about the similar issuse, we approach in a way that does not require using weighted spaces. Although our approach share a similar spirit to previous studies, our method seems to be more precise and natural.

Enzymes are biodegradable catalysts naturally present in living organisms. Enzymes can accelerate biochemical reactions by reducing the activation energy, and they are not consumed during reaction processes. Numerous applications of enzymes have been developed in biotechnology, industry, medicine, pharmaceuticals, food processing, biofuels, and so on. In this study, we develop a mathematical model describing enzymatic reactions with a Ping-Pong mechanism and competitive substrate inhibition. In order to obtain insights into the model behaviors, we use Python software to obtain numerical solutions for the model. Some discussions on the numerical results is provided. Finally, we briefly discuss a potential application of the model and some future work.

Ficus hispida L.f. (FH) is among the widely cultivated tree species in Asian regions. The aim of this work was to determine phenolic and flavonoid contents, antioxidant, in vitro anti-inflammatory activities of FH extracts prepared with methanol (ME), ethanol (ET) and ethyl acetate (EA). The extract obtained from ethyl acetate contained the highest total phenolic and flavonoid contents (92.75 +/- 5.14 mg GAE/g and 5.67 +/- 0.65 mg QE/g), followed by ME and ET. The capacity to scavenge ABTS free radical of the extracts followed the order: EA > ME > ET while their DPPH activity differed insignificantly. The inhibitory effect of EA and ME (IC¬50 = 362.84 +/- 29.05 and 386.95 +/- 11.10 ug/mL, respectively) were higher than that of ET. Correlation analysis showed a high positive correlation between total phenolic content and ABTS activity. The findings of the study would be useful for development of new nature-derived agents for prevention and treatment of diseases.

In recent years, society has been evolving rapidly, and contemporary education is being adapted to satisfy people's requirements in accordance with 4.0 trends and the industrial revolution.This gives birth to the definition of Smart University, the study of which seeks to identify the required components for constructing a smart learning environment. The research group analysed nationally and internationally advanced models, proposing a smart university model for Thu Dau Mot University (T-SMARTHS) with smart levels matching the phases established and developed at Thu Dau Mot University.

Glioma is a deadly tumor that accounts for the majority of malignancies of the brain and central nervous system. Currently, applying biomarkers and combining with clinical treatments in the diagnosis and prognosis of Glioma is the optimal trend. Among the effective biomarkers, microRNA has emerged as a novel, efficient biomarker. In this study, we used data from the Kyoto Encyclopedia of Genome and Gene Routes Database (KEGG) and bioinformatics tools for functional prediction and annotation of two Glioma-associated molecules (miR-6780a-5p and miR-6754-3p). The result indicated that 361 genes relating with two molecules miR-6780a-5p and miR-6754-3p. In which, miR-6780a-5p interacts with 198 genes and miR-6754-3p interacts with 166 genes. PPI analysis (protein-protein interaction analysis) and functional enrichment analysis revealed that target molecules of two miRNAs (miR-6780a-5p, miR-6754-3p) belong to cancer signaling pathways such as MAPK (Mitogen-activated protein kinase) and WNT (Wingless-related integration site). In addition, two miRNAs (miR-6780a-5p and miR-6754-3p) affect not only Glioma but also regulation in many other cancers such as pancreatic, thyroid, and endometrial cancer. Briefly, the result has clarified the role of (miR-6780a-5p, miR-6754-3p) in regulating signaling pathway of Glioma, thereby evaluating the interaction between miRNAs, target genes and target signaling pathways, and also supporting for the selection of potential biomarkers in Glioma diagnosis

Vietnamese immigrants in the United States encounter a variety of acculturation issues that affect them as individuals, families, and as members of their communities. It is evidenced in the literature that low-socio status immigrants suffered from those acculturation challenges. However, there is scant research on how acculturation affects high-socio status immigrants in general and Vietnamese American immigrants in particular. To better understand how high-educated Vietnamese families coped with acculturation in the United States, this research used semi-structured interviews to examine the acculturation issues they encountered and the techniques they utilized to overcome those issues. Four well-educated participants were interviewed one-on-one for 20-30 minutes each by Google Meet in Vietnamese whenever they were available. The interviews were transcribed using unfocused transcription, and the data was analyzed using grounded theory technique. Results showed that high-educated Vietnamese immigrants in the United States face three major acculturation challenges: orientation, the necessity of better economic and self-esteem needs. However, women seemed to be under more acculturative stress owing to their lower levels of English proficiency and work satisfaction, according to the findings. In terms of coping methods, the husbands use integration acculturation tactics to deal with their issues. Separation methods were adopted by the women at various periods in their life, despite the fact that they are eager to become fully integrated members of American culture. They are unable to do so due to a lack of urgency and lack of access to cultural integration.

Recognized as a smart city, Binh Duong's smart city development strategy also includes the development of automated agriculture, typically large-scale livestock farming. A sustainable urban development will not be able to ignore the factor of providing food for urban and regional people. Phu Giao district - Binh Duong province is one of the leading districts in livestock farming, especially concentrated pig farming. The agricultural industry, pigs breeding, is one of the strengths of the district, besides the cultivation of short and long-term industrial crops such as rubber, cashew, Ho Tieu... Livestock is a very old profession of the Vietnamese people in Phu Giao district as well as in Binh Duong province. The contribution of livestock production to the socio-economic face of the district cannot be denied. However, animal husbandry activities, besides the economic values, also cause some consequences to the natural environment such as soil and water pollution, noise, odors in the air, etc. Hence, we decided to do the research of "Application of ISO 14001:2015 international standards in determination of environmental aspects at market hog farm with semiautomatic technology farm size 12,000 pigs per year in Phu Giao district, Binh Duong province" (TCVN ISO, 2015). This is a large-scale pig farm with modern semi-automatic technology equipment. We expect to find out environmental issues in the most detailed and specific way so that the owner can overcome the above environmental problems, rest assured to raise livestock and develop more expansion later. We conducted a review of the areas on the farm, evaluated the activities in each area, from which we found out the environmental problems through the material flow diagram (Phạm Thị Hồng Cẩm, 2020). Next, through the multi-criteria method (Phạm Thị Hồng Cẩm, 2020) we calculated the score and found the most significant environmental aspects (most environmental risk). The research results will be a general picture to provide farm owners with an intuitive and easy-to-understand view for suitable solutions. Developing farm economy along with environmental protection towards sustainable development of livestock agriculture.

In this article, the primary purpose is to design and implement a remote light control example that makes use of the Arduino IDE platform for programming, the MQTT protocol, and an ESP32 microcontroller, which has a dual-core CPU as well as Wi-Fi and Bluetooth capabilities. This aspect is related to the Internet of Things (IoT), which allows any fundamental device to be linked and become a smart device via the application of the Internet. As a result, these devices can be operated from a significantly long-distance, eliminating the need to physically interact with the switches to turn them on or off. The first part of the paper is a discussion of the fundamental theory that is provided to examine the potential of remote control methods, followed by a short overview of the Arduino integrated development environment (IDE), MQTT communication protocol, and PWM technique to regulate the brightness of lights. The second section is devoted to hands-on work, such as setting up an environment connection over the Internet, compiling and designing a printed circuit board (PCB).

This article is the results of the project "Assessment of health and safety risks for wood industry workers researched at Lap Giai company, Ben Cat district, Binh Duong province".

The experiences drawn from the theory of change in transdisciplinary study are (1) Can be applied to digital transformation research and environmental management research in enterprises. (2) Role leadership is decisive in developing transdisciplinary topics in enterprises. (3) Both internal and external environments must be considered to design the most beneficial change interventions.

For more than a hundred years, the people of Kien Giang have maintained the celebration of Nguyen Trung Truc’s death anniversary in order to pay tribute to this “Born as a general, die as a god”. According to the movement and development of history, the death anniversary of Nguyen Trung Truc must also have certain changes, to match the content anh nature of the historical – cultural time. This is an important issue, helping to better identify the regular adaptations and changes of national cultural values. However, to date this issue has not been studied. The purpose of the article is to analyze and clarify the process of organizing the death anniversary celebration and its changes, contributing to explaining the adaptation and regular change of cultural values.

Oral history is both a method of gathering information and an important source of historical data in social history and public history. The narratives of individuals are not only exploited to find historical facts or “additional” details to a grand narrative but uncover the meaning of individuals’ stories for a broader social context. That shift has made oral history increasingly an interdisciplinary research method. However, compared with the popularity of oral history in international academic disciplines, the application of this research method restricts in Vietnam. This article presents the possibilities and prospects of oral history through different research topics/fields in history, at the same time, specify the causes of obstacles to the legitimization of oral history in Vietnam.

Cho Lon was a former province in southern Vietnam, now part of Ho Chi Minh City and Long An Province. During the Vietnam War from 1945 to 1954, Cho Lon province exemplified the practice of an all-people, all-out war across military, political, economic, and cultural fields. Using the method of writing history through oral narratives, this paper presents the process of organizing and developing general education in Cho Lon province in conjunction with the resistance movement led by the Democratic Republic of Vietnam. The results show that the Democratic Republic of Vietnam in Cho Lon province organized and developed general education throughout the resistance, even during the most intense periods of the war. The development of general education in Cho Lon province became an integral part of the resistance, contributing to its momentum and strength, and helping to achieve victory in the fight against French colonial invasion. The educational development in Cho Lon province from 1945 to 1954 provides valuable lessons for building an educational system during wartime.
