Dermatophytosis is a common superficial fungal infection in dogs and cats, caused by dermatophyte species, characterized by typical skin lesions and the potential for zoonotic transmission, particularly in high-risk groups. This study aimed to identify the risk factors associated with dermatophytosis in dogs and cats in Hanoi. A cross-sectional study was conducted at 11 veterinary clinics in Hanoi from May to July 2024. A total of 152 dogs and cats were examined, including 48 cases diagnosed with dermatophytosis and 104 non-affected animals. The case group consisted of dogs and cats exhibiting clinical signs and testing positive by at least one diagnostic method (KOH preparation, Wood's lamp examination, and/or culture on Sabouraud agar. Twenty-five potential risk factors were analyzed using univariate logistic regression, of which 12 showed associations with dermatophytosis (P <0.1). Multivariate logistic regression identified three statistically significant risk factors (P <0.05): the animal’s age, the presence of other pets with dermatophytosis in the same household, and the practice of boarding pets at pet hotels during the owner's absence. The results highlight the need for screening, environmental hygiene and infection control in multi-pet households and animal care facilities.

Mycoplasma infectious in pigs causes long-term economical impact for Vietnam’s swine husbandry. The present study compared hematological parameters between non- and infected sows complying with blood smear Giemsa staining for pathogen’s detection. Physiological indicators for red blood cell qualities such as RBC, HCT, MHC and MCHC were lower in sick group (P <0.05). AST, indirect bilirubin and creatinin of infected pigs were significantly elevated compared to healthy pigs. In contrast, blood glucose was lower than that of healthy oigs (P <0.05). ALT, urea and direct bilirubin showed no significantly difference between two groups. Unique feature of purple round or oval M. suis staining with Giemsa were captured on the surface of RBC or scattered in plasma of blood smear. Erythrocytic pathology was characterized by stellate degeneration and deformation at various degrees. Hematological indices in this study not only determine the status of M. suis infection but also confirm the stage of infection. Giemsa staining with simple protocol can be a applicapble diagnostic method for practical conditions in Vietnam.

The emergence and widespread dissemination of colistin-resistant E. coli is a significant challenge to both human and animal health. This study aimed to determine the prevalence and antibiotic resistance profile of colistin-resistant E. coli isolated from raw pork sold at traditional markets in Dong Anh, Hanoi. E. coli was isolated using culture on selective media. The antibiotic resistance of E. coli was determined using a microbroth dilution method following the guidelines of the Clinical and Laboratory Standards Institute. The mcr gene was detected by multiplex-PCR. The results of this study showed that 26% (13/50) of the pork samples were positive for colistin-resistant E. coli. High resistance levels were observed for florfenicol, ampicillin, streptomycin, tetracycline, trimethoprim/ sulfamethoxazole, and nalidixic acid, with resistance rates ranging from 84.62% to 100%. All colistin-resistant E. coli isolates were identified as multidrug-resistant strains and carried the mcr-1 gene. These findings highlight that raw pork poses a potential risk for the transmission of colistin-resistant E. coli from meat to humans, thereby increasing the risk of antimicrobial-resistant bacterial infections in the community.

This study was conducted to assess factors influencing land use planning for urban and industrial development in Duy Tien town, Ninh Binh province. The combined methods used in the study were secondary and primary data collection, data processing, scaling measurement construction and correlation determination. The results showed that there were 06 factors, including: investment attraction policy factor, investment capital source factor for planning implementation; people's living standards, natural conditions and natural resources, urbanization speed and urbanization level, and regional linkage in urban and industrial planning. There were 06 factors with medium positive influence: environmental protection policy in urban and industrial planning, Eonomic structure, culture, customs, and practices, natural disasters and climate change, urban land use structure with urbanization process and traditional historical factors in urban and industrial development. On that basis, some effective solutions to improve land use planning for urban and industrial development in the study area have been proposed.

Acidic whey obtained from tofu whey fermentation is a natural coagulant commonly used in traditional tofu production, contributing to the characteristic properties of the product such as softness, coolness and smooth texture. Lactic acid bacteria predominate in this fermentation process. This study aimed to isolate and characterize the morphological, physiological, and biochemical properties, and by using molecular biology techniques identify to the species level of some lactic acid bacteria present in the natural fermentation of tofu whey. Twenty-eight lactic acid bacterial strains were isolated on MRS agar supplemented with CaCO3, exhibiting typical opaque white, round colonies and Gram-positive staining, some strains were able to grow at 45C and produced gas from glucose. The 16S rRNA gene sequencing identified two isolates as to Limosilactobacillus fermentum and three isolates as Weissella confusa.

This study aimed to analyse the status and effectiveness of high-tech adoption in agricultural cooperatives in Ho Chi Minh city. Data were gathered from 2019 survey by semi-structured questionnaires administered to representatives of 14 cooperatives, 5 enterprises, and 5 government officials. The findings indicate that these models of high-tech adoption generate positive economic, social, and environmental outcomes. Specifically, cooperatives adopting high-tech reported higher revenues and profits than non-adopters. Nearly 50% of respondents stated that high-tech helps reduce input costs such as fertilisers, irrigation water, and pesticides. However, the share of cooperative members and land area under high-tech remained limited. The main constraints included finance, land, misaligned training, weak market linkages, and gaps in after-sales services. Policy recommendations included value-chain-based credit with cooperatives as lead coordinators, field-based training, and standard-form contracts with digital traceability to strengthen contract discipline and scale up urban high-tech agriculture.

In the context of climate change, resource degradation, and rising demand for safe food, green agriculture has emerged as an inevitable development trajectory. A review of research from 2010 to 2024 in Japan, the Netherlands, the United States, Australia, and Vietnam indicates that governments play a pivotal role through stable regulatory frameworks, green credit schemes, extension services, and quality standards, while enterprises contribute capital, technology, value-chain development, and public-private partnerships. These incentive mechanisms generate positive impacts across three pillars: economic (enhanced productivity and value added), social (food safety assurance and sustainable employment), and environmental (emissions reduction and resource conservation). However, challenges persist, including high costs, institutional fragmentation, technological constraints, and climate-related risks. International experience underscores the necessity of long-term policies, flexible financial instruments such as preferential credit, risk-guarantee funds, results-based PPPs, standards linked to traceability, digital transformation, and market-based tools such as payments for ecosystem services or carbon credits. Collectively, these lessons highlight the importance of designing incentive packages tailored to local contexts, accompanied by monitoring and evaluation systems to ensure effectiveness and sustainable development.

Developing new rural areas at the village level is a new approach that aims to enhance the role of local communities as key actors in the National Target Program on New Rural Development. In the context of administrative reorganization, the need to strengthen autonomy, self-governance, and intermediary role of villages in connecting the state with communities has become increasingly urgent. However, theoretical research on this issue remains limited and lacks systematic analysis. This paper employed synthesis and analysis of literature from research studies and policy documents to systematize the key theoretical issues, including concepts, connotations, criteria, characteristics, and influencing factors. The findings contribute to enriching the theoretical foundation, suggesting policy directions, and opening pathways for further research.

The article discussed several theoretical issues related to digital competence of university undergraduate students using information and data from domestic and international relevent publication. The article focused on some key aspects: the concept and the role of digital competence for undergraduate students, the major digital competence frameworks developed in Vietnam and in the world. The review of existing studies revealed that digital competence is one of the key competencies for students to effectively engage in learning and working in open educational environments and digital society. Different digital competence frameworks have been developed globally, and the European Commission’s DigComp 2.1 was considered as one of the most comprehensive. In Vietnam, the digital competence framework for learners issued by the Ministry of Education and Training served as the primary tool for assessing digital competence for learners, however it does not fully addressing specific digital competencies needed by undergraduate students. The article, therefore, suggests a digital competence framework for undergraduate student, including 6 main competency groups divided into 18 component criteria.

The article focuses on systematizing the theoretical and practical foundations of working capital management capabilities in small and medium-sized enterprises (SMEs). Building upon and developing theoretical models from previous studies, the article structures working capital management capabilities into five groups: planning capability, executive capability, control capability, analytical capability for evaluating working capital efficiency, and coordination capability. At the same time, it analyzes both internal and external factors that influence working capital management capabilities in SMEs. On this basis, the study contributes to developing an analytical framework that serves as a foundation for empirical research aimed at enhancing financial management effectiveness within the SME sector.

This paper explored key theoretical issues and proposes a research model regarding young farmers' intention to use social media platforms for agricultural product marketing in the context of rapid digital transformation scenario. Employing literature review method combined with content and thematic analysis of academic sources, the study clarified the concept of social media, identified relevant tools, and reviewed foundational theories and theoretical models related to the intention to adopt social media in agricultural product distribution among young farmers. The literature synthesis indicates that young farmers played a critical role in promoting sustainable agricultural development. They can engage in one or multiple stages of the agricultural value chain including production, processing, and marketing to enhance productivity, quality, income, and environmental sustainability. Moreover, their active participation contributes to improving the competitiveness of domestic and international agricultural products and helps mitigate the adverse effects of disease outbreaks and climate change. Going forward, it is essential for young farmers to proactively embrace digital transformation tools, particularly in the marketing and distribution phase of agricultural products at the local level.
