European Trade on the Far East and the Mercantile Relationship with Vietnam from the 16th to 19th Century

The 16th century witnessed a significant start for European maritime trade on the Far East, triggering by the pioneer Portuguese. Though being not a great market as compared with China, Japan, Indonesia in the Far East, Vietnam still attracted many European empires by an abundant quantity of merchandise as well as a strategic position on the international trade route. The Portuguese, Dutch, British and French respectively represented themselves in Vietnam, with somewhat different interests, paying much attempts to establish a stronghold for trade there. Nonetheless, their trade in Vietnam had become feeble since the end of 17th century. That was explained by several reasons

The Hue Citadel Area in the Transition of Urban Composition During the Rise and Fall of the Nguyen Dynasty in the 19th Century

The history of the old Hue City intertwined closely with the fortunes of the Nguyen Dynasty. After the citadel area was chosen as the capital of a unified Vietnam from 1802 by Emperor Gia Long (the founder of the Nguyen Dynasty, 1802—1945), the appearance of Hue changed rapidly towards urbanization. In the first period from 1802 to 1884, urban composition was informed along the course of the Huong River by royal sites, of which the core was the Hue citadel – an admirable combination of geographical space and human talents, handicrafts works, and commercial space. That made Hue an interesting historical landscape albeit its narrow space for a broader urbanization. However, with incoherent policies on the economy, diplomacy as well as religious conflict, the Nguyen Dynasty was not able to avoid an invasion by the French Empire or to save itself from decline. Being home to a defeated native dynasty, Hue became powerless in both economy and administration under French colonization, in spite of the fact that modern industrial locations were partly encouraged to be built here from 1884. The present paper attempts to give a general view on the urban composition and urbanization of Hue based on the two political periods of the feudalistic period (1802—1884) and period of colonization (1884—1899)

An inquiry into the determinants of Vietnamese product export

Export led growth is the model of economic development that Vietnam has been following. While there are a great number of studies on the determinants of aggregate export of Vietnam, there are few that analyze the impacts of different factors on the export of different product groups. This paper aims at filling this gap in research on international trade of Vietnam. The results show that the fast GDP growth of Vietnam, the large population of importing countries, the wide economic gap between Vietnam and the importing countries, the depreciation of domestic currency, the free trade agreements that Vietnam signed and the shared border with the importing countries contribute to the increase of Vietnam’s export of all product groups. In contrast, the GDP of importing countries and population of Vietnam have no clear impacts on the export of any product groups.

Design and fabrication of a moving robotic glove system

This paper presents the research, design, and manufacture of a robotic hand to control movement with a glove. The moving glove-controlled robotic hand is based on two main parts: the hand mechanism and the control circuit. The control glove unit includes an Arduino nRF24l01 microcontroller module and five flex sensors for five fingers. These sensors are used to collect data about the curvature of each finger. Then those data will be received by the Arduino microcontroller and sent by the nRF24l01 module. The hand's microcontroller will process that information and control five servo motors so that the five fingers of the robotic hand are moved. The result of this research is to produce a robotic hand that accurately simulates the curvature of a user's finger and mimics the motion of a glove well. Moreover, the robot hand can grip objects of different sizes (from 0.1 to 1 kg) and shapes, from which this robot helps users easily manipulate objects

Impacts of Economic Development on the Living Conditions of Ethnic Minority People in the Border Region of Northern Vietnam

Purpose:   In this study, we examine the effects of the economic development policies of the Vietnamese government on the living conditions of ethnic minority people in the border region of Northern Vietnam.   Theoretical framework: We examine the impact of economic changes, societal changes, and environmental improvements on the living conditions of ethnic minority people in the border region of Northern Vietnam.   Design/Methodology/Approach: The collected data was subsequently cleaned and analyzed using Partial Least Squares Structural Equation Modelling (PLS-SEM) with the aid of SPSS 20 software.     Findings: The results show that the current Vietnamese government’s policies on developing agriculture, industry, trade, and service for ethnic minority people have a diverse impact on their living conditions. In general, agriculture, trade, and service are major fields that benefit the living conditions of ethnic minorities. In contrast, the industry seems to have no effects on improving the standard of living of ethnic minority people in Northern Vietnam.   Research, practical & social implications: The results of this study provide suggestion to Vietnamese government on promoting living conditions of ethnic minority people in the border region of Northern Vietnam.   Originality/Value: This is the first paper evaluates the impact of the economic development policies of the Vietnamese government on the living conditions of ethnic minority people in the border region of Northern Vietnam

Vers un modèle de vérification de la couche logique d'entreprise dans une architecture à 3 couches: modèle CPN-ECA

International audienceThis paper proposes a model for building a flexible system, which accepts and verifies the change on business logic, including both business processes and business rules, while the system has to cover the properties as reliability and reuse. In this model, the business process will be designed with Colour Petri Net and translated into a set of Event-Condition-Action rules, this set will be combined with business rules for checking the respect of a business process to the business rules in design and modifying the process. Hierarchical Colour Petri Net is also used to guarantee the reliability and to reuse properties of the system.Ce document propose un modèle pour la création d'un système flexible, qui accepte et vérifie les modifications apportées à la logique métier, y compris les processus et les règles métier, tandis que le système doit couvrir les propriétés en termes de fiabilité et de réutilisation. Dans ce modèle, le processus de gestion sera conçu avec un réseau Pétri coloré et traduit en un ensemble de règles Event-Condition-Action (ECA). Cet ensemble sera combiné à des règles de gestion permettant de vérifier le respect du processus de gestion par modifier le processus. Un réseau Pétri coloré hiérarchisé est également utilisé pour garantir la fiabilité et pour réutiliser les propriétés du systèm
