The study empirically investigate the relationship between tourism receipts, exchange rate and economic growth in the period 1990-2017 and define whether the tourism -led growth (TLG) hypothesis for Vietnam. The study implements Vector Error correction Model, Granger causality tests, variance decomposition with data in the periods 1990 -2017.
Media relations is one of the very important tools of PR (Public Reations) and also an effective tool in handling media crisis. In addition, in the current technology boom, managing - controlling information sources on social networks is a difficult job that requires the media departments of enterprises to set up strategies and enhance skills to limit the risks brought by communication crises.
By using qualitative research methods of comparing and contrasting some experiences from various smart-tourism models of China and Korea, this study may be able to help Da Nang city improve its image significantly and foster guests’ experiences as well.
Providing readers the evaluation of the impacts of outsourcing in the hospitality industry on performance and service quality within the context that restaurants and hotels are short of staffs post COVID-19 after they attempted to cut down a number of employees in order to reduce the operational costs and maintain the operations of business establishments. Therefore, managers can utilize this approach to fill up their role positions in a short-term and gradually seek other alternative stable and skillful labours in the long-term.
Constructing an evolutionary-algorithm-based cantilever retaining wall design approach. Differential Evolution (DE) and the feasibility rule-based constraint-handling (FRBCH) method are integrated to achieve the research objective. A DE based software program incorporating FRBCH has been developed with Visual C# .NET to facilitate its implementation.
Manufacturers constantly have to encounter fluctuated product demands. Accordingly, it is required to establish a production schedule that meets the future demands and concurrently has a low level of daily labor/materials’ deviation. This study constructs an evolutionary algorithm for achieving this task. The Differential Evolution (DE) algorithm and the feasibility rule based method for constraint handling are integrated to develop this evolutionary algorithm. The proposed approach has been verified by two cases of production scheduling.
This paper reviews air pollution situation in Ho Chi Minh city and Ha Noi. We also recommend policies to tackle the problem: (i) upgrade the national air quality standard, (ii) install systematic and high-quality network of monitor stations, and (iii) remove means of transport that unmet emission regulations.
This study aims at developing a computer vision tool to detect defects on surface of civil engineering structures by means of Gaussian steerable filters. This tool has been developed with Visual C#. NET to facilitate its implementations. The developed software programs have been tested with images containing various defects such as crack, pothole, and spalling.
Nghiên cứu so sánh, phân tích một cách hệ thống tiêu chuẩn TCVN 13594-8:2023 với các chuẩn quốc tế điển hình, từ đó chỉ ra những điểm tương đồng, khác biệt và các khoảng trống kỹ thuật. Trên cơ sở đó, bài báo đề xuất các khuyến nghị hoàn thiện tiêu chuẩn Việt Nam theo hướng bổ sung thông số định lượng, mở rộng yêu cầu thử nghiệm, thiết lập cơ chế bảo trì vòng đời và tích hợp nội dung kháng chấn.
