Factors Affecting the Bank Credit Accessibility of Rural Households in Vietnam

The research identifies and measures factors affecting the bank credit accessibility using Heckman (1979). The research uses data from dataset of Vietnam Household Living Standard Survey (VHLSS) in 2014 and 2016 to eliminate the shock due to the global economic crisis in 2008-2009 making the estimate unsustainable. The results show that among the factors that can affect the bank credit accessibility considered in the first stage of Heckman model, there are six factors that significantly and statistically affect the bank credit accessibility of rural households. These factors include the household’s average income, householder’s age, ethnic group, marital status, previous loan period and members of the Farmers Associations. The estimate results obtained from the second stage of Heckman model on the possibility to receive loans of rural households in Vietnam indicates seven factors affecting the value of loans received from bank credit institutions are the household’s average income, householder’s age, ethnic group, marital status, previous loan period and members of the Farmers Associations

Does PAPI Monitoring Improve Local Governance? Evidence from a Natural Experiment in Vietnam

This study, using the Viet Nam Governance and Public Administration Performance Index (PAPI) surveys, examines the effect of monitoring local authorities on the quality of governance and public services in Vietnam. PAPI randomly selected 200 locations in 93 districts of 30 provinces to conduct survey in 2010 and rolled out nationally in 2011 and 2012. Using 2011 and 2012 survey data, we compare these provinces and their districts with those that were not surveyed in 2010. Theories suggest that local authorities may improve their behavior if they have been surveyed and know that they are being monitored. In this paper, we find that governance quality reported by citizens in the surveyed provinces and districts of the 2010 PAPI survey is significantly higher than in other locations. This monitoring improves a wide range of governance aspects, including local participation in village decisions, transparency of local decision-making, accountability, administrative procedures, and public service delivery

Social Assistance Policy in Vietnam: Issues In Design And Implementation, and Vision For Reforms

This study aims to outline the vision for the Vietnamese social protection system. It provides discussion of the issues of implementation and performance of the current programme design, especially the issues of budget allocation, implementation and monitoring are explored using qualitative evidence from provincial and local administrators. New analysis based on the data from the Vietnam Household Living Standard Survey (VHLSS) 2010 will be conducted to look at overall performance in targeting and coverage. Finally, it outlines the constraints and opportunities that inform a road map for the future vision of social assistance within an overall system of social protection

F2SD: A dataset for end-to-end group detection algorithms

The lack of large-scale datasets has been impeding the advance of deep learning approaches to the problem of F-formation detection. Moreover, most research works on this problem rely on input sensor signals of object location and orientation rather than image signals. To address this, we develop a new, large-scale dataset of simulated images for F-formation detection, called F-formation Simulation Dataset (F2SD). F2SD contains nearly 60,000 images simulated from GTA-5, with bounding boxes and orientation information on images, making it useful for a wide variety of modelling approaches. It is also closer to practical scenarios, where three-dimensional location and orientation information are costly to record. It is challenging to construct such a large-scale simulated dataset while keeping it realistic. Furthermore, the available research utilizes conventional methods to detect groups. They do not detect groups directly from the image. In this work, we propose (1) a large-scale simulation dataset F2SD and a pipeline for F-formation simulation, (2) a first-ever end-to-end baseline model for the task, and experiments on our simulation dataset.Comment: Accepted at ICMV 202

THÀNH PHẦN HÓA HỌC VÀ HOẠT TÍNH KHÁNG VI SINH VẬT GÂY BỆNH CỦA TINH DẦU TỪ VỎ BƯỞI DA XANH (Citrus maxima (Burm.) Merr.)

Pomelo is a Vietnam’s plant species with high nutritional and economic value. Besides, pomelo essential oil contains numerous compounds with high biological activity. The essential oil is extracted by using steam distillation, and its chemical composition is determined by means of GC-MS. The major components are limonene (91.19%), b-myrcene (2.92%), a-phellandrene (1.98%), and a-pinene (1.19%). The antimicrobial activity of essential oils is tested against pathogenic Gram-positive bacteria (Bacillus cereus, Staphylococcus aureus), Gram-negative bacteria (Escherichia coli), and Aspergillus flavus at different concentrations with the agar well diffusion method. This essential oil is active against B. cereus, S. aureus, and E. coli with inhibition diameter zones at 8.3–11.3, 10.3–18.7, and 9.0–11.7 mm, respectively, and inhibits A. flavus mold with 18.9–65.0% efficiency.Bưởi là loài cây không chỉ có giá trị cao về mặt dinh dưỡng mà còn có giá trị cao về mặt kinh tế và được trồng phổ biến ở Việt Nam.

Gut Microbiome of Patients With Breast Cancer in Vietnam

PURPOSE: Gut microbiota play an important role in human health, including cancer. Cancer and its treatment, in turn, may alter the gut microbiome. To understand this complex relationship, we profiled the gut microbiome of 356 Vietnamese patients with breast cancer. MATERIALS AND METHODS: Stool samples were collected before chemotherapy, with 162 pre- and 194 postsurgery. The gut microbiome was measured by shotgun metagenomic sequencing. Associations of gut microbial diversity, taxa abundance, and gut microbiome health index (GMHI) with sociodemographic, clinical factors, and tumor characteristics were evaluated. RESULTS: Postsurgery samples were associated with significantly lower α- and β-diversities ( CONCLUSION: Our study revealed that diagnosis delay, high fiber intake, and breast cancer surgery, which is always followed by antibiotic prophylaxis in Vietnam, led to a less diverse and unhealthy gut microbiome among patients with breast cancer
