This paper explores the pros and cons of using online setting for teaching and learning English comparing with in-class setting. Online setting is undergoing a fast transformation and becomes a widely promoted platform due to COVID-19 pandemic. By reviewing different studies on online teaching, this paper aims to provide readers a better understanding about online setting. These information would be useful in Vietnam where online class just has a medium used and short history comparing with other developed and developing countries, so online class in Vietnam may need adjust and consideration based on different culture and learner’s experience. This paper also give some suggestions in design of online learning for English languages to increase the learning effectiveness.

Electric vehicles (EVs) making a significant contribution to the reduction of fossil fuel consumption and CO2 emissions are expected to thrive in Vietnam in the upcoming years/in the near future. However, such vehicles’ energy demand could become a burden on the transmission networks, causing overloads to the electric grid of the nation. Hence, to solve this problem, a solar PV system can be utilized to fulfill the electricity needs in an EV charging station. This article presents the design, simulation and economic analysis of a grid-connected solar power system for an electric charging station at Thu Dau Mot University (TDMU). The photovoltaic (PV) power system is designed to supply energy to the charging station and office building. The study estimates the generated electricity, the efficiency of the PV power system and the ability to reduce CO2 emissions. This paper can be a recommended input for stakeholders to consider using this energy source for charging vehicles.

Automation or automatic control has been a growing trend in industrial fields as well as in life because of the advantages and utilities that help optimize work and reduce manpower in production. In medium and large scale automatic control systems, PLC (Programmable Logic Controller) is used as the control device for the system. In production, the transmission system using motors takes a large proportion and the problem of controlling for them to operate correctly, meeting technological requirements is one of the difficulties that need to be solved. In this study, we have applied PLC to stabilize motor speed according to preset value using PID algorithm integrated in Siemens S7–1200 PLC in order to apply research results in practice. At the limit of the article, we will present the issues of PID function block configuration, programming algorithm flowchart for PLCs, and monitoring console design for a small DC motor drive system model to verify.

SARSCOV-2 virus and new strains have been spreading in most countries and regions around the world, the COVID-19 epidemic it causes has infected millions of people, the urgent need is to prevent their spread. On the market there are many types of hand wash equipment automatically spray disinfectant solution used with many different sensors and operating principles, but most are still using AC power. In this topic, we design automatic hand washing equipment by applying the transmitter and receiver principle of the moving infrared sensor circuit and delay relay circuit to detect someone appearing in the observation area, click activating the MP3 reader circuit plays the “5K” propaganda sound about Covid -19 disease prevention and the position sensor activates the mini-pump to spray the hand-washing gel within a certain detecting distance. We have conducted experiments and completed our projects with devices that use energy from solar cells, through charging circuits and storage batteries with the goal of using renewable energy, minimizing impact of the greenhouse effect.

Environmental issues such as the wastewater have influenced each aspect of our lives. For human and environmental health protection, it is necessary to remove excess zinc in industrial wastewaters before discharging them to environment. Modified diatomite displayed larger surface area and pore volumes in comparison with untreated natural diatomite, which favored heavy metals sorption behavior. In this study, the removal of Zn(II) ions from aqueous solution was studied using Fe/Mn modified diatomite sample at different adsorption parameters such as contact initial metal ions concentration, dosage of Fe/Mn-Diatomite and ionic strength Na2CO3 on ionic Zn2+ adsorption capacity of diatomite modified. The residual zinc concentration in the solution was determined using flame atomic absorption spectroscopy. The results showed that: the gravitational increase increases with increasing time and then becomes almost stable, with 120 minutes timeliness; absorption increases when Fe/Mn-Ditomite is increased, absorption reaches 89.48% at a dose of 1.5 g/l; additional different concentrations Na2CO3 ranged from 0 ppm to 80 ppm the results showed that performance treatment Zn2+ of correspond 94,85%. This study could lay an essential foundation to develop modified diatomite for heavy metal removal from wastewater.

Youth in a nation is the most viable and potential human resource in both demographic and social structure. Without the youth's adequate and integrated bio-social development a nation cannot attain its anticipated human goals. Based on government initiative a2i, the empowerment of youth towards sustainable development in Bangladesh is described in this paper. Although the Bangladesh Government has formulated and implemented policies, plans and programs for youth welfare are still through GOs and NGOs. Related literature indicates that, regardless of all age and regions, young people in this country face several socio-cultural problems where they cannot grow and empower themselves adequately. As a result, they cannot play their important roles in sustainable development and changes within the country. To resolve the problems of the youth in relation to their development and empowerment, the Government of Bangladesh is developing and implementing some solutions. The case study focuses on the role of a2i for development of youth in the successful design of public development and sustainable development programs.

Activity recognition is one of the preliminary steps in designing and implementing assistive services in smart homes. Such services help identify abnormality or automate events generated while occupants do as well as intend to do their desired Activities of Daily Living (ADLs) inside a smart home environment. However, most existing systems are applied for single-resident homes. Multiple people living together create additional complexity in modeling numbers of overlapping and concurrent activities. In this paper, we introduce a hybrid mechanism between ontology-based and unsupervised machine learning strategies in creating activity models used for activity recognition in the context of multi-resident homes. Comparing to related data-driven approaches, the proposed technique is technically and practically scalable to real-world scenarios due to fast training time and easy implementation. An average activity recognition rate of 95.83% on CASAS Spring dataset was achieved and the average recognition run time per operation was measured as 12.86 mili-seconds.

Corrosion of the bottom of the petroleum tank may lead to a product leak that could cause a fire or explosion resulting in damage to people and the environment, therefore the test of tank bottom corrosion is necessary to be conducted periodically to prevent the occurrence of the above problems. In non-destructive inspection, the Magnetic Flux Leakage (MFL) method relies on the variation of fluxes caused by defects on the surface of materials to detect corrosion, pitting, or imperfections, which is proved quite effectively with low cost. The project was implemented to develop a prototype of the MFL bottom detection device based on the research results in the world to improve corrosion survey capacity in industrial equipment, as well as to improve the expertise in the Research Team of electronics and automation in the fields of magnetic fields and sensors. As a result, an MFL model using permanent magnets and Hall sensors were fabricated. Survey experiments showed that the machine could detect corrosion defects up to 20% of steel wall thickness in the scanning speed range from 500 mm/s to 1130 mm/s. However, to meet the actual survey needs, the team must continue to improve the device in terms of sensitivity, scanning speed, the ability to operate automatically or semi-automatically, and register for a fire safety inspection.

The paper presents general theory about making small models for studying large machines. Here, the author refers to the design of pile driving and pressing machines. To express ideas, the author presents design drawings presented in three-dimensional perspective. Currently, pile drivers and pile presses are two separate machines, in which their base machine is the same, their working parts are slightly different. The author takes advantage of the slight differences to combine them into one machine, so as to ensure that this machine is able to pile or pile. In addition, the structure of pile making and pressing machines is created by the author, which is somewhat simpler than the current construction and driving machine. This successful study will form the basis for manufacturing a pile driving machine and pile machine into a single machine, greatly reducing the costs of procurement and construction machine use.

Across the world, the first accounting course provides serious challenges for teaching. These arise from powerful negative perceptions which include the anxiety associated with tertiary-level study and the differing backgrounds or majors of students required to take the course. This paper outlines some examples of nontraditional teaching techniques and highlights how the course could be best structured to overcome such negative views while at the same time responding to the changes in the industry. The design and content of the proposed course emphasizes the USER approach and is directed to English as second language learners. This is a case study in an Australian offshore campus and is the end result of the progressive improvement in the structure and delivery of the course.

This study investigated grammatical difficulties encountered by students of the People’s Police University while learning grammar in ESP courses. The design included questionnaires to teachers and students, and classroom participant observations. The findings indicated that the student respondents only perceived four target features to be difficult to learn. The results also showed that the students’ perceptions of grammatical difficulty were influenced by several factors including the inherent complexity of rules, L1 transfer, students’ differences in language aptitude, students’ infrequency of practice, and teaching methodology. The findings will hopefully be useful for teachers and researchers with an interest in this line of research.

Đề xướng CDIO hay sáng kiến CDIO (Conceive Design Implement Operate) là một dự án quốc tế lớn nhằm cải cách chương trình đào tạo và phương pháp giảng dạy của các trường kỹ thuật bậc đại học. Còn AUN-QA (ASEAN Uni versity Network – Quality Assurance) là bộ tiêu chuẩn với các quy tắc chất lượng khắt khe, có tiêu chí cụ thể, rõ ràng, tập trung đánh giá những điều kiện để đảm bảo chất lượng đào tạo của toàn bộ chương trình đào tạo của các trường đại học Đông Nam Á. Từ năm 2013 cho tới nay, trường Đại học Thủ Dầu Một đã ứng dụng không ngừng những tiêu chuẩn và tiêu chí của cả CDIO và AUN vào việc xây dựng chương trình đào tạo, đổi mới phương pháp dạy học và kiểm định chất lượng đào tạo để đáp ứng những tiêu chuẩn khắt khe của những sản phẩm đầu ra, đáp ứng yêu cầu xã hội và hội nhập khu vực, tiến tới hội nhập quốc tế về giáo dục và đào tạo. Ngành Quốc tế học tuy mới được thành lập ở trường Đại học Thủ Dầu Một từ 2019, nhưng cũng đã áp dụng rất triệt để bộ tiêu chuẩn CDIO và AUN từ khâu lập đề án mở ngành cho tới xây dựng đề cương giảng dạy, tuyển sinh đầu vào và đổi mới phương pháp dạy – học. Bài tham luận của chúng tôi sẽ tập trung vào sự kết hợp xây dựng chương trình đào tạo và đổi mới phương pháp giảng dạy theo những bộ tiêu chuẩn CDIO và AUN mà chúng tôi đã và đang áp dụng triển khai có hiệu quả ở ngành Quốc tế học.

Bài báo này đề cập đến chương trình đào tạo sinh viên ngành Công nghệ Kỹ thuật điện tử kéo dài 4 năm đã được triển khai tại trường Đại học Công nghệ Đồng Nai. Các sinh viên phát triển kiến thức và kỹ năng từ người mới học điện tử trở thành người có kinh nghiệm như các nhà thiết kế mạch. Chương trình đào tạo mang tính định hướng cao và tất cả các học phần đều tập hợp xung quanh một bộ tiêu chuẩn đã được xem xét kỹ lưỡng. Chương trình đào tạo đặt trọng tâm vào bốn dự án thiết kế – triển khai (dự án kỹ thuật, dự án kỹ thuật đa ngành, thực tập chuyên ngành và khóa luận tốt nghiệp) và tuân thủ đúng các nguyên tắc CDIO (Conceive – Design – Implement – Operate: Hình thành – Thiết kế – Triển khai – Vận hành). Ở năm đầu tiên, dự án có độ khó thấp, thách thức tăng lên đáng kể trong những năm tiếp theo. Sinh viên học được rằng thiết kế sản phẩm là một quá trình lặp đi lặp lại ở các cấp độ khác nhau. Các đánh giá đã chứng minh rằng sinh viên không chỉ nhận thức được các nguyên tắc CDIO mà còn bị thuyết phục bởi chất lượng đào tạo khi tuân theo các tiêu chuẩn này.

Đề xướng CDIO: C (Conceive): Hình thành ý tưởng, D (Design): Thiết kế, I (Implement): triển khai, O (Operate): vận hành. Ở tiêu chuẩn 8 - Học tập chủ động và trải nghiệm, với tinh thần của tiêu chuẩn này, nhóm tác giả thực hiện bài viết ứng dụng tiêu chuẩn 8 vào học phần xây dựng hệ thống quản lý môi trường – ISO 14001có tính chất thực hành nhằm phân tích cách thức thực hiện tiêu chuẩn theo tinh thần của đề xướng. Trong học phần thực hành, Giảng viên hướng dẫn sinh viên học tập chủ động bằng cách giao cho sinh viên chọn lựa một địa điểm mà sinh viên dễ dàng tiếp cận thực hiện phân tích các điều khoản và xây dựng hệ thống. Đối với tiêu chuẩn quốc tế ISO 14001 thì việc hiểu tiêu chuẩn đã khó, tiếp cận một đơn vị để ứng dụng việc hiểu của mình còn khó hơn. Với việc xây dựng được hệ thống quản lý môi trường, buộc sinh viên phải được tiếp cận gần nhất với đơn vị, được đơn vị tiếp nhận và tạo điều kiện quan sát làm bài. Việc giảng viên cho sinh viên lựa chọn bất kỳ đơn vị nào, và khuyến khích sinh viên chọn các đơn vị là những nơi sinh viên đang làm thêm, nơi quen biết để sinh viên có nhiều điều kiện để quan sát và thực hành.

On the basis of coordinating the sources of history materials from Vietnam and China, together with the latest archaeological achievements of Ho citadel, the article has delineated territory, confirmed the chronology frame with the Kings of this kingdom in relation to post-Champa Empire. It is from the aftermath of Vijaya, the two parts of Aryaru (Phu Yen) and Kauthara (Khanh Hoa) belong to Hoa Anh Kingdom, in which, Le Thanh Tong is crowned as Ban La Tra Duyet; the rebellion of this King is the cause for the second conquest, formally taking Ling Chan/ Da Bia as the landmark; Trai A Ma Phat Am is designated as Hoa Anh’s King on the remaining land of Kauthara, but immediately incorporated into Panduranga, forming the state of post-Champa.
