In order to have an overview of the current quality of youth labor and its readiness for the emergence of the fourth industrial revolution (or Industry 4.0), measuring the understanding of students about the Industry 4.0 in the context of Vietnam's digital economy is essential. As the young's perception in the present-day context can be seen as a crucial manifestation to evaluate their awareness levels on how this revolution impacts their joining the labor market. In addition, the young’s awareness is an important information source in orienting their own behavior accordingly, which is also an indication of the level of their willingness to adapt to the digital age. As the result of previous qualitative and quantitative surveys, this article addresses the awareness characteristics of young people, thereby exploring their capacity for self-assessment about risks or career opportunities in the context of Industry 4.0.
Study on sampling sludge from 04 industrial parks in Binh Duong province such as My Phuoc, Dong An, Viet Huong 1, Song Than 2 to analyze the pollution criteria to assess the pollution possibility of industrial waste sludge. The research results show that: at present, the total volume of sludge generated today in the industrial park fluctuates about 4,450 – 6,255 kg/day, equivalent to dry sludge volume is 1,035.725 – 1,532.11 kg/day. The estimated volume of dry sludge generated from industrial parks in the future from 2019 to 2020 ranges from 30,023 to 31,396 kg/day. Most sludge from 04 wastewater treatment plants hadn’t heavy metals (Hg, Pb, Cu, Ni, Cr, Zn, Cd), especially Dong An Industrial park Treatment plant had Zn, value 49.7 – 49.9 mg/l. The sludge from the wastewater treatment plants of 04 industrial parks had amount of helminth eggs that exceeds the USEPA's regulations on pathogens (type A sludge).
Bien Hoa City is an urban area of Dong Nai province located in the Southern key economic region. Currently, Bien Hoa City has 6 industrial parks in operation with large daily wastewater flow, causing environmental risks, especially from organic pollutants. The study applied the Nemerow risk index and the geographic information systems (GIS). The results showed that the industrial parks were mainly organic pollution levels including N-total, P-total, and Ammonium. The level of environmental risk from organic pollution was recorded in range of medium to very high levels, the ranked in descending order: Agtex Long Binh Industrial Park (P = 24)> Amata Industrial Park (P = 16)> Bien Hoa 2 Industrial Park ( P = 10),> Tam Phuoc Industrial Park (P = 5)> Loteco Industrial Park (P = 3). The results of the study provided good information for the management and improvement of wastewater quality in the industrial wastewater treatment plants of the industrial parks in Bien Hoa City.
This paper examines the main challenges of the processes of space and social policy change present to current urbanization trends of Taiwan. The chapter argues that one of the main challenges is economic growth, increasing integration into the global economy and making Taiwan competitive in the global economy. This process leads to the growth of large urban regions that present many challenges to the urban development in the future. In particular, the paper focuses on the most fragile areas of the extended urban spaces are the rural and urban margins, where urban activities are expanding into densely populated agricultural regions. It is argued that in these areas, local policies should be developed that adapt to local ecosystems. The paper presents lessons of interventions in this field for Ho Chi Minh, Dong Nai and Binh Duong Region for urban expansion.
With the development of information technology, many applications of robots are increasingly being applied to support research, learning, and teaching. This paper mainly investigates the modeling and simulation of a robotic arm with 3 degrees of freedom (dofs) for different applications. First, Kinematics and dynamics model of the robot based on the standard Denavit Hartenberg (D-H) modeling method, where the forward kinematics of robot is analyzed and computed to obtain by using the inverse kinematics, and then the solution of the robot dynamics is derived. Second, a CAD model of the robot is designed on CATIA software to convert to MapleSim software to simulation and control. Final, numerical simulation is presented to display results. This work provides a potential basis for the realization of the robotic arm in the industrial, education, and research field, which is of great significance for improving manufacturing efficiency and support teaching and research in the robot field.
Along with changes in Economy, Tourism and the influence of foreign waves, the market of Food Service in Vietnam has also changed to meet the needs of customers. At many restaurants in Vietnam, customer satisfaction can greatly affect restaurant revenue. Therefore, it is essential to determine which perceived quality factors affect customer satisfaction. The survey was conducted through questionnaires collected from 329 respondents, who experienced in restaurant services in Vietnam. In this paper, four factors are found that have influence on customer satisfaction in restaurants: Service quality, Product quality, Environment and Price. In addition, the research also gives some contributions based on the research results, helping businesses understand customers and meet customer satisfaction requirements in the restaurant.
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.
Most of the indoor accidents are related with fall down. Many medical studies are point out that key factor for keeping patient’s life is fast response of monitoring system. In modern life, peoples are isolated with neighbor, especially in living quarters. Therefore many solutions are developed for falling down monitoring that base on wearable sensors. These methods require of an expensive sensors system with electric power supplier and telecommunication devices. In context of patients with disease and weak status, patients are trend to remove sensor system. This issue requires to find out another approach so that sensors system will not be needed. We study the fall detection by monitoring camera. For increase the accuracy, we proposed a simple and effective method to extract features of abnormal activities. By tracking the magnitude of entropy and its distribution, our fall detection model has a capability of differentiating falls from other activities
The fifth generation (5G) cellular network has been commercialized recently to fulfill the new demands such as very high data exchange rate, extra low latency and high reliability. Many new technologies have been introduced and exploited since the early of the 2010s. Among these emerging technologies, full-duplex relaying cognitive radio networks, device-to-device communications and cell-free massive multiple-input and multiple-output have been considered as promising technologies/systems for 5G and beyond. This work provides a comprehensive study on the concepts, advantages and challenges of the above-mentioned technologies. In addition, we also introduce four new research directions which are challenges of 5G and beyond.
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.
In this paper, we first introduce a new class of bilevel weak vector variational
inequality problems in locally convex Hausdorff topological vector spaces.
Then, using the Kakutani-Fan-Glicksberg fixed-point theorem, we establish
some existence conditions of the solution for this problem.
Caodaism was established in the South in 1926. It has been considered as one of indigenous religions in Vietnam in the first half of 20th century. In the first days, trend of Caodaism was to develop in foreign countries through missionary campaigns. Cao Dai’s dignitaries carried out missionary task in Cambodia, France, German, China… That was why followers of Cao Dai (Cao Dai followers) lived in these countries in the early 1930s. After 1975 many people in the South emigrated to America, Australia. Many of them were Cao Dai followers. After their lives have been stabilized, they have gathered to build temples so Caodaism in foreign countries has developed strongly. The number of believers in foreign countries is about 50,000 believers. They have created connection with Cao Dai sects through many forms. In this article we mention three main contents: 1) Cao Dai followers in foreign countries: the process of establishment and development after 1975; 2) The administrative relation between Cao Dai followers in foreign countries and Cao Dai church in Vietnam; 3) Some remarks on the administrative relation. The information in this article has been completed with two research methods: in-depth interview and participate observation.
