    Opis:
    This paper presents the results of an assessment of change in urban green spaces in Thanh Hoa city (Vietnam). Sentinel 2 MSI data in 2015 and 2021 are used to calculate 3 parameters: percentage of green, weight of green types, and weight of proximity to green. These parameters are used to calculate the Weighted Urban Green Space Index (WUGSI). The final result shows the distribution of green space in the study area consisted of very high-quality green, high-quality green, moderate quality green, and low quality green. The obtained results show that the quality of urban green space in Thanh Hoa city has changed significantly in the period 2015-2021, in which the area with category “low quality green space” increased from 7.17% up to 9.48%; areas with category “very high-quality green space” reduced from 65.02% to 47.39%.

    Opis:
    The studFigy aims to determine the TNF-α single-nucleotide polymorphism TNF-α (-308) and assess the association of TNF-a(-308) SNP with the risk of silicosis among workers directly exposed to silica dust in Vietnam. A study was undertaken among 78 cases with silicosis and 103 controls without silicosis in Vietnam. Blood samples were collected for genomic DNA extraction from each subject. The phenotyping of TNF-α(-308) was performed using polymerase chain reaction‐based restriction fragment length polymorphism (PCR‐RFLP) and dye termination sequencing. Results: The average exposure time of the case group was slightly higher than that of the control group (12.46 ± 6.732 years vs. 12.09 ± 7.854 years). The majority of genotypes in both silicosis and non-silicosis was GG. When analyzing the concentration of TNF-α in the study participants' blood, it is shown that the average concentration of TNFα in the case group was higher than that in the control group. The genotype AG in the case group was 1.368 times higher than that in the control group. The percentage of all A alleles in the case group with silicosis was 1.342 times higher than the control group without the disease, similar to previous studies. Conclusion: The majority of genotypes in both groups was GG. The average concentration of TNF-α in blood, genotype AG, and the percentage of all A alleles in the case group was higher than that in the control group.

    Opis:
    Apatite ores type III of Lao Cai area, Vietnam is a class of weathered sileceous apatite ores, which may have most variable composition and primary slime content according to the weathering level and location. The three operating flotation plants use similar single-stage grinding circuits to process the highly weathered sileceous apatite ores and to achieve the concentrate grade requirement of 31% P2O5 with the aimed average recovery of about 70%. Single stage grinding circuits have worked well in the past as the designed criteria were achieved, however, mine production has increased sharply and deeper ores are being mined recently, so that the material composition of the run of mine ores have become more complicated and are the ores become more difficult to be floated. As a result, processing criteria of these plants become critically unstable and low. The study is to investigate the suitabity of two-stage grinding circuits for Lao Cai apatite ore type III. The report presents the results of the study on middlings regrinding of hard floatable apatite samples of Bac Nhac Son flotation plant, where high loss of valuable apatite has occured due to low grinding performance. Research results show that regrinding of all middlings to the fineness of 75% -0.04mm not only improves recovery but also help to stabilize technological operations and their processing criteria. The final concentrate grade of more than 31% P2O5, tailings content of less than 5% P2O5 and recovery of over 70% were achieved.

    Opis:
    The impact of Free Trade Agreement (FTA) on commercial business of the member could be assessed by the potential and tangible effects. This paper is adopted by Partial equilibrium theory and SMART tool to measure the impact of EVFTA on the Vietnamese meat import (HS code 02). The result of this model is claimed that EVFTA has a huge impact on boosting the meat import from EU to Vietnam. However, the value of import in this category from European nations in each country and good fluctuated significantly. This study also proposes some measures for domestic businesses and the government to ensure the benefits on Vietnam’s livestock industry. Last but not least, meat quality management is one of vital issues under EFVTA and global competitiveness to meet higher expectation of consumers. Good food (meat) manufacturing practices need to be applied. That is the social contribution value of this paper.

    Opis:
    Dimension-stone quarrying optimization is significantly important to increase the recovery ratio of dimension stone and to reduce the cutting cost. Due to fracture-existed rock mass, in the mining operation block size and mining direction influences to the recovery ratio and the cutting cost. Therefore, the paper suggests the quarrying optimization for dimension stone to obtain the highest recovery ratio and the lowest cutting cost, based on optimizing block size and mining direction to get a cutting grid of dimension stone. Through developing an integrated modelling between joint set modelling and cutting grid modelling, intact blocks and fractured blocks were generated. From this, block statistics were conducted to get the maximum recovery ratio of dimension stone and the minimum cutting rate between the cutting area and the recovered block volume, which helps to choose an optimizing block size and mining direction. The research was carried out at Tan Long dimension stone quarry where a block size (0.9m x 0.6m x 1.35m) and a mining direction paralleling to joint set 1 will ensure the highest recovery ratio of 13.87% and the lowest cutting rate of 25 m2/m3.

    Our study aims to analyze and assess the process of reforming the specialized inspection procedures in Vietnam which is included in Vietnam’s trade facilitation implementation program, and suggesting some recommendations for Vietnam to do the reform to improve business environment and enhance Vietnam’s national competitiveness. By synthesizing and analyzing secondary data from creditable sources such as World Bank, UNESCAPE, UNCTAD, WTO, VCCI, General Department of Vietnam Customs, as well as interviewing officials from Ministry of Industry and Trade of Socialist Republic of Vietnam, etc. Ha and Lan (2021) stated Economic regulatory reform in Vietnam started in the early 1990s and accelerated when the country shifted its focus to economic integration policy by acceding to the World Trade Organization (WTO) in 1995 and engaging in regional free trade agreements in the Association of Southeast Asian Nations (ASEAN). After analyzing and assessing the real situation of Vietnam’s trade facilitation and specialized inspection reforms, this paper would like to suggest some recommendations to continuously implement specialized inspection reforms, implement trade facilitation, improve Vietnam’s business environment and enhance Vietnam’s national competitiveness.

    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.
