Opis:
Tourism is one of the most important factors in economic growth in Vietnam. However, it requires the balance between economics, social-cultures, and ecology because of their big impacts. In this paper, we propose a platform with mobile and web-based applications that can support smart and sustainable tourism in Vietnam for both local governments and visitors. The mobile application allows visitors to access location-based services to explore the visiting area, such as finding nearby natural attractions, as well as information to minimize the negative effects of tourism on the environment and the local community. It also enables users to report negative impacts to local government. The web application allows local authorities to monitor the status and trends of the habitant, natural environment, tourism infrastructure and activities in the area. The system uses geographic information systems (GIS) and remote sensing techniques to collect, analye and visualize various indicators of sustainability. The platform is developed with open-source technologies such as NodeJS, PostgreSQL, and Flutter. The paper demonstrates the feasibility and usefulness of the proposed platform through case studies in Hoa Binh and BacKan, two provinces have many attractive natural sites.

Opis:
In surface mining operations, the operating costs of truck-shovel system constitutes 50-60% of the total. Only a little save in the operation costs in this system will bring large profit for the mines. Due to many investment periods, the capacity of both trucks and shovels in Cao Son surface coal mine is different. This leads to the low efficiency and the difficulty in dispatching strategy for the mine. This paper presents the current situation and selection of advanced dispatching strategy for increasing the efficiency trucks and shovels at this surface coal mine. The results show the detailed match factor reflects the state of each team of loader and trucks and should be use as the indicator for dispatching decision for the heterogeneous truck and shovel fleet at Cao Son surface coal mine.
