Mobile internet and income improvement:Evidence from Vietnam
New developments of existing technologies over time have led to emergent patterns of technology adoption and accordingly changing impacts on economy and society. Focusing on the arrival of mobile Internet in the early 2010s in developing countries, we identified significant positive effects of mobile Internet on provinces’ average household income in Vietnam. The effect sizes are larger for lower-income quintiles groups and for rural areas, suggesting the more inclusive changing impact of the innovation over the last decade. Preliminary evidence of impact mechanisms via skilled employment rates and (formal) wages are also presented. The evidence from Vietnam, a lower middle-income country, can bring further understanding in the extent of development impacts of second-generation mobile for development (M4D 2.0) in particular and ICT for development (ICT4D) in general

Methods of using character and language in stories to teaching Vietnam history from 10th century to 18th century in high school
This paper aims to proposes methods of using stories about historical figures in teaching Vietnamese
history (from the 10th to the 18th century), with a focus on the interest of students with lessons.
Vietnamese history (from the tenth to eighteenth centuries) has an important position in the entire
development process of the nation's history. This was the independent feudal period, the period that
witnessed the rise and fall of Vietnam's feudal system through the stages, the period that made its mark
with the resistance wars against foreign invaders. This passage has many national heroes, typical
characters, cultural celebrities with great influence on history, is an extremely rich and diverse source of
materials for teachers to exploit and put into teaching. History subject in high school helps students to
understand deeply and remember historical events for a long time. At the same time, building emotional
stories about historical figures will help shape good character and educate students on patriotism. In the
study, quantitative methods and qualitative methods were used. The data were collected using statistics
of Vietnamese historical figures from the 10th to the 18th century, survey questions for students and
teachers, number of test scores after each lesson, assessment of learners' feelings, Positive, creative and
conscious attitude of students. The study results show that students enjoy the lesson, actively participate
in the lesson as well as enthusiastic about the teacher's problem questions. Through lessons in telling
stories of historical characters, students' abilities are developed at different levels: knowing,
understanding, applying and creating.Tan Trao University in Tuyen Quang, Viet Na
Using Brainstorming Techniques In Teaching Vietnamese History From 1858 To 1918
Today, teaching history in high schools not only equips students with basic and systematic
knowledge about the history of the lawful development of the nation and human society, but also
teaches love country, national pride, training thinking and ability to practice the subject. With such a
great role, improving the quality of history teaching in high schools will contribute to the realization
of training goals. In order to improve the quality, it is necessary to synchronously innovate from
objectives, programs, textbooks to teaching methods, testing and evaluation. In which methodological
innovation is one of the basic requirements because the teaching process in general and history
teaching in particular is a complex process, including many factors, in which, the teacher - Students
are the most important factor. The article focuses on clarifying the importance of brainstorming
technique, as well as the advantages and disadvantages of this technique for teaching Vietnamese
history in the period 1858-1918.Tan Trao University in Tuyen Quang, Viet Na
Cultures and Works of Tay People Through Vocative Words
Culture has a close relationship with many fields, including Linguistics. Language is a special product of culture. It is a means of communication and a tool for thinking. Language is a means to reflect, maintain and develop culture. Any meaningful sign of a language contains a cultural element. Vocative words are one of those cases. The article explores the vocative words system in the language of the Tay people in Tuyen Quang Province, Vietnam and concludes that culture is not only a factor that generates language, but also an environment for language to exist and develop. develop. Through the system of vocative words in the Tay language, it shows the cultural characteristics of respect affection of the Tay people
Antibacterial activity of Piper betle extracts on Helicobacter pylori and identification of potential compounds
Helicobacter pylori is one of the most common infectious bacteria in the world that causes gastric diseases leading to cancer. The increase of multiple antibiotic resistance rates of H. pylori have been reported worldwide. Thus, development of novel drugs is urgently required. Piper betle has many therapeutic values in traditional medicine. In this study, therefore, we investigated antibacterial activity of P. betle extracts and their fractions against a H. pylori strain isolated in Vietnam. The agar disk diffusion assay showed inhibition zone of ethyl acetate extract and methanol extract from P. betle leaf that of were 46 mm and 32 mm in diameter, respectively. After fractionation of the ethyl acetate extract through silica gel column chromatography, two peaks, PD2 and PD3, out of 12 fractions showed the strongest antibacterial activity. PD2 was sub-fractionated further by re-chromatography on the silica gel column, and subfraction TK12 gave best resolution on LC-MS analysis. Finally, 4 potential compounds, quercetrin, calodenin B, vitexin and plicatipyrone, were identified in TK12 fraction.
Recurrent neural networks for structured data
A key challenge in machine learning is to explore and incorporate the complex nature of real-world data structures into the training models. The contributions of this thesis are novel RNN architectures for different types of structured data
