A study on growth and food spectrum of Reeve’s croaker was carried out from June 2021 to January 2022 in the coastal areas from Soc Trang to Bac Lieu provinces. Fish samples were collected monthly by bottom trawl.Fish stomachs were fixed in a 4% formol solution to prevent feed items from being digested in the stomach. The analysis of 198 male and 215 female samples showed that the total length (L) and body weight (W) of the fish had a regression relationship according to the equations Wmale = 0.0064L3;1425 and R2= 0.9735 (totallength ranged 14.0 – 40.0 cm) and Wfemale = 0.00463:2425 and R2 = 0.9504 (total length ranged 13.5 – 41.0 cm). The relative length of the gut (RLG) < 1 (RLG = 0.08 ± 0.02 cm in immature fish and RLG = 0.08 ± 0.04 cm in mature fish),indicated that Reeve’s croaker was a carnivorous fish. Many individuals in the population haveno food in their stomachs. The immature fish eat three types of food (small fish, shrimp and other food) while mature fish eat six types of food (small fish, shrimp, squids, crabs, nereid and other food). The feed spectrum of immature fish was narrower than that of mature fish.

The study was conducted to assess the current status of technical and financial aspects to contribute to proposing solutions and to overcome the development directions for the square-head climbing perch culture next time. The study was carried out in Hau Giang Province from February to May 2020 through interviewswith 44 farmer households in a well-designed form. The results showed that the average yield is 11.5±4.43 tons/1,000 m2/crop, the average profit is 16.4±23.5 million VND/1,000 m2/crop, the high total production cost is 283.1±114.9 VND/1,000 m2/crop, in which the food cost is the highest with 84.6%. The benefit ratio was0.06 times and there are 64% of net profit and 38% of net loss farmers. The factor of survival rate, fingerling size, density stocking, experience, price, FCR and pond water level impacted yield and profit. Besides the advantages of natural conditions and self–supply fingerling, the squarehead climbing perch system currently faces many difficulties, such as capital shortage, product output depending on traders’ price, product standards, and harvest time.

The study was conducted from June to December 2021 to assess the technical – financial aspect and the existing advantages and difficulties of the giant freshwater prawn culture in coconut garden ditch culture by interviewing 32 farming households in Thanh Phu district, Ben Tre Province. The study results showed that the average area for each ditch was 0.38 ± 0.29 ha, with density stocking 4.15 ± 1.21 PL/m2. For prawns were harvested after over 8 months, the prawn yield was 421.08 ± 172.21 ton/ha/crop, the profit was 34.02 ± 14.02 million VND/ha/crop and the benefit ratio was 1.33 ± 0.56 times. The yield and the profits were affected by density stocking and nursing survival rate. Besides the advantages of labor resources, natural conditions, and ease and less risk of giant freshwater prawn culture; however, the system currently faces many difficulties, such as lower nursing survival rate, unguaranteed quality, and quantity of postlarvae, salinity intrusion, unstableproduct market. Therefore, in order to contribute to sustainable aquaculture development, the necessary solutions include (1) providing high quality and quantity of postlarvae; (2) using settling ponds to have active water; (3) building and improving infrastructure, and irrigation systems to prevent salinity intrusion; and (4) finding the product market.

Using polysystem theory, the article examines the conceptions of literary researchers in Vietnam in establishing main standards in the process of literary evaluation. As a result, researchers often choose two basic andcommon standards: political and humanity. In particular, since the Renew (1986) until now, humanity standards have been considered by some researchers as a valuable category in the literary studies in Vietnam.

Nano-silver technology for cosmetics preparation is quite popular in recent times because nano-silver is non-toxic and has good antibacterial properties used to create products for skin protection purposes. This studyinvestigated the preparation of a cream product that brings a moisturizing effect with hyaluronic acid and antibacterial effects with nano-silver extracted from natural, environmentally friendly passion fruit peels. The product not only meets the market demand but also brings outstanding efficiency in the application of the antibacterial properties of nano-silver to users. This study investigates the excipient ingredients to preparea complete formula cream containing nano-silver with antibacterial and skin moisturizing properties. The nano-silver lotion formula was developed by evaluating the ability of excipient emulsions including oil phase - water phase excipients, emulsifying excipients, excipients with moisturizing effect, and the ratio of nano-silver.After that, the cream was evaluated for sensory, pH, skin irritation, moisturizing ability, and antibacterial ability on some strains of bacteria. The study was success in preparing a moisturizer containing nano-silver synthesized from passion fruit peel extract, satisfying the properties of a cosmetic product and encouraging further research.

The Provincial Competitiveness Index is increasingly being studied in scholarly articles. In 2021, the index was completed and added new indicators to increase the overview, comprehensiveness, and support of the state apparatus in the provinces and cities in public administration and investment attraction. Using the ProvincialCompetitiveness Index 2021 Report, the authors have made statistics and analyzed the competitiveness indicators of Vinh Long Province. With theoretical synthesis and analysis of secondary data, the study concentrates on transparency indicators, aiming to detect the positive aspects as the limitations of the province in the context of comparison in the Mekong Delta. Through the results, the authors have proposed the UTAUT2model to create a theoretical framework to increase the participation and use of electronic information in the business community, which improves PCI and determines the direction of public administration in the coming time.

In the first twenty years of the twenty-first century, ecological literature in the Mekong Delta appeared in many works with typical genres such as poetry and short stories. Many writers and poets are concerned about the reality of the environment happening in the delta, so they have integrated and included issues with a clearecological consciousness in their works. To answer the question of why eco-conscious literature appeared in the Mekong Delta, the article focuses on explaining the issues of natural, social, and cultural conditions and environmental changes. Ecology affects the sense and responsibility of the writer. Thereby, it shows that each region with different natural, cultural and social conditions has a more or less impact on the formation ofliterary characteristics in each region, especially for eco-conscious literature. A literary work expressing ecological consciousness often refers to environmental changes that have a negative impact on human life. The literary works relating to this issue mainly mention the consequences that people have suffered from climate change, soil, water, air, and flora or reveal people’s attitudes and feelings towards the situation they are witnessing. Therefore, the natural, cultural and social conditions and their changes directly affect the formation of a part of literature with ecological consciousness in this area.

Histopathology is the most important issue in research pharmacy and clinical medicine. Microdiagnosis is a method of identifying and orienting treatment as well as disease prognosis. In testing acute toxicity, the youngleaves of mangoe extract (Mangifera indica L., MIL) was investigated based on analysis and comparison of liver/kidney microstructure of normal mice (Mus musculus L.) and mice that drank at high doses of MIL. The liver and kidney of laboratory mice were separated from groups of normal mice drinking distilled water (physiological control), normal mice drinking 1000 mg/kg, normal mice taking 2500 mg/kg and rats taking5000 mg/kg b.w., only one time. The observed results showed that the microstructure of the liver/kidney of rats drinking methanol extract MIL were damaged when compared to physiological control mice. This means that high doses of MIL have adverse effects on the liver/kidney of normal mice. From these results, it is concluded that MIL extract should not be taken arbitrarily not only in the body with any pathogenesis but also in the healthy body without the guidance of the pharmacist.

Tetralogy of Fallot is a common cyanotic congenital heart disease. Early surgery treatment gives patients a chance to have normal physical and mental health due to preventing complications of cyanosis and even death as a natural history of tetralogy of Fallot. This study aimed to show short-term outcomes (including the time of postoperative hospital stay and 30 days after discharge) of tetralogy of Fallot complete repair at the Department of Pediatric Cardiac Surgery, Cho Ray Hospital. A retrospective study was performed on the dataof medical documents of 38 patients, who underwent complete repair for tetralogy of Fallot with full sternotomy and cardiopulmonary bypass from March 2017 to December 2019, following a collection form. The results showed the average age and weight were 33.89±13.02 months and 11.77±2.48 kg. The cardiopulmonary bypass time was 147.74±12.48 mins, the aortic cross-clamp time 104.84±9.73 mins, the mechanical ventilation time 31.14±10.75 hours, the duration of stay in the intensive care unit 58.03±13.56 hours, the postoperative hospital stay time 10.12±1.5 days, and the mortality rate 2.6%. The study concludes that the short-termsurgical outcome of complete repair for tetralogy of Fallot in lightweight children is safe and effective with a low mortality rate.

Early surgery treatment gives patients a chance to have normal physical and mental health due to preventing complications of cyanosis and even death as a natural history of tetralogy of Fallot. This study aimed to show short-term outcomes (including the time of postoperative hospital stay and 30 days after discharge) of tetralogy of Fallot complete repair at the Department of Pediatric Cardiac Surgery, Cho Ray Hospital. A retrospective study was performed on the dataof medical documents of 38 patients, who underwent complete repair for tetralogy of Fallot with full sternotomy and cardiopulmonary bypass from March 2017 to December 2019, following a collection form. The results showed the average age and weight were 33.89±13.02 months and 11.77±2.48 kg. The cardiopulmonary bypass time was 147.74±12.48 mins, the aortic cross-clamp time 104.84±9.73 mins, the mechanical ventilation time 31.14±10.75 hours, the duration of stay in the intensive care unit 58.03±13.56 hours, the postoperative hospital stay time 10.12±1.5 days, and the mortality rate 2.6%.
