The goal of the article is to examine the relationship between supply chain risk, Supply chain integration, Supply chain risk resilience and Firm performance in the global supply chain of the Vietnamese pharmaceutical industry. Data was collected for 3 months with 389 satisfied pharmaceutical enterprises for analysis on Smart PLS software. The results show that Supply chain risk has a statistically significant negative impact on supply chain integration. Moreover, Supply chain Integration has a statistically significant positive impact on Supply chain risk Resilience and firm performance. Finally, we find that Firm performance is a good foundation for business operations and supply chain risk resilience. Therefore, we make recommendations to Vietnamese pharmaceutical enterprises that: Supply chain Integration is extremely necessary to ensure performance and Supply chain risk resilience in the context of the current covid-19 pandemic.

The article is purposed to assess the impact of corporate entrepreneurship on organizational culture, supply chain management performance and business performance. Particularly, it examines the moderating role of organizational culture and corporate size on the relationship between corporate entrepreneurship and business performance. The research is carried out on 96 chemical companies in Vietnam, using PLS-SEM technique. The results indicate that organizational culture and company size had moderating role effected positively by corporate entrepreneurship to business performance through organizational culture and supply chain management performance. .

Seafood processing operations generate a high strength wastewater, which contain organic pollutants in soluble, colloidal, particulate form and salt content, up to 30g NaCl/L. This research aimed to study the effect of salt (NaCl) concentration on the treatment efficiency of seafood processing wastewater by the use of a laboratory-scale bioreactor, which is operated in anaerobic combining aerobic system with concentration salt different from 0-5%. The results showed that the wastewater from seafood processing with the chemical input parameters of pH = 7 -8.5, COD = 2000 mg / L, total nitrate nitrogen = 150 mg / L, NH 4+ = 90 mg / L, total phosphorus = 50 mg / L, salt content 3% was treated with anaerobic activated sludge content of 8000mg/l, 16HRT and combining an aerobic activated sludge content of 6000mg/l, 6HRT, DO=2-4mgO2/l with the acclimatization of 7% bacteria Bacillus velezensis at high salinity The parameters output wastewater was treated according to standards QCVN 11-MT:2015/BTNMT (column B).

The overuse of antibiotics is losing its effectiveness due to increased antibiotic resistance in bacteria. Over the last two decades, the evaluation of antibiotic residues in the environment has greatly attracted the attention of researchers around the world. The more new groups of antibiotics were validated to use in medical treatment, the more antibiotic residues were discharged into the environment. In this work, a combined SPE-UPLC-MS/MS method was developed and validated for simultaneously analyzing 9 antibiotic compounds belonging 3 different groups which are tetracyclines (tetracycline – TET, chlortetracycline – CHL, oxytetracycline – OXY), fluoroquinolones (ciprofloxacin – CIP, norfloxacin – NOR, ofloxacin – OFL) and macrolides (azithromycin – AZI, erythromycin – ERY, clarithromycin – CLA) in surface water. All target analytes were separated on a reversed-phase column (Water BEH C18 column, 1.7 µm particle size, 100 x 2.1 mm) coupled with a mass in tandem employing positive electrospray ionization (+ESI). All target analytes were well separated with an overall run time of 16 minutes. The limit of detection was from 0.2 to 10 µg L-1. The extraction process has been successfully optimized using the HLB column (Oasis, 6mL, 200mg, Waters) with recoveries from 71 to 125%. The optimized method was finally applied to analyze ten surface water samples (lake and river). OFL, CLA, and ERY were most found in lake samples at concentrations from 35 – 570.3 ng.L-1 while only CIP was found in all river samples. The other compounds were also detected in both types of samples but the concentrations were lower than the quantification limit.
