Vietnam's seafood processing industry, in the specific, and the agricultural industry, in general, has gained many benefits and achievements to contribute to the GDP growth of Vietnam in recent years. Using qualitative analysis, synthesis, and inductive methods, with statistic data, this study examines the theories of inter-industry clusters or groups views applied in the agriculture and seafood processing industry, esp in a case study of the Tra fish (Pangasius hypophthalmus) in Mekong Delta River in Vietnam. Our results relate to seafood processing in the case study of fish pangasius in the Mekong delta in Vietnam. For instance, the present study shows that making seafood from tra fish (or pangasius describes processing fillet Tra fish (Pangasius hypophthalmus) in a 3-step process. Last but not least, through our analysis, analysis had suggested suitable agricultural policies. In conclusion, the empirical results have shown that making fillet Tra fish needs to have enough experience and skills under certain conditions. Besides, our study also indicated that increasing the application of new technologies in the rearing stage of fish such as: using probiotics, vaccines, and rearing in cool houses to increase the resistance of fingerlings to improve survival rate and efficiency for production. Finally, the empirical results have shown that the process of making fillet tra fish (pangasius) needs to have enough experience, skills and take place under certain conditions.

As fast growth of Vietnam banks going with risk policies, We categorize listed banks on Vietnam stock exchange into 2 groups: Previous SOEs banks (including Vietcombank and Vietinbank) and Previous Private banks (including SHB, EIB and ACB). Authors then use combination of quantitative methods (statistics, calculation formulas) and qualitative methods including synthesis, inductive and explanatory methods. The research findings tell us that In groups of banks (SOEs previously) VCB and CTG we find out: G and Risk free rate (Rf) have higher impacts on beta CAPM, for internal factors. While In groups of joint stock banks (private banks) SHB, ACB and EIB we figure out: exchange rate and SP500 have higher impacts on beta CAPM, for external factors. Besides, this study also give out recommendations for enhancing socio-economic roles of Vietnam banks in future and give out directions or implications for socio-economic policies.

Our study will specify solutions for internal control of cost estimation design in road and bridge construction units in Hanoi-Vietnam. Authors mainly use methods of comparison, analysis and synthesis; investigate; summarizing experience; The above methods are used in combination for the purpose of reviewing and evaluating the problems of the research object of the article: theory and practice of internal control for the estimating design of bridge - road in construction units based in Hanoi, period 2015 to 2020. Our research findings show that we need to invest in information technology, purchasing modern computers and backup equipment. Especially those who operate, repair computers and update basic information for design software. Also, the contractor's personnel organization must be flexible to changes in the policy mechanism, i.e interchangeable in the professionalization posture. Finally, author also propose other solutions for better internal control.

The Industrial Revolution 4.0 based on digital technologies has led to an unprecedented change in the socio-economic model. Therefore, countries in general and Vietnam are all aiming to develop the digital economy. The concept of digital transformation of the economy or development of the digital economy in Vietnam focuses on the following basic contents: 1) Developing digital businesses; 2) Digital transformation for traditional businesses (towards digitally integrated products; transforming business models on digital platforms; changing production processes based on digital data, automation, virtualization, etc.); 3) Development of digital finance; 4) E-commerce development. Therefore, digital transformation becomes an inevitable and objective trend, supporting banks to overcome challenges, create competitive advantages, and actively adapt to the context of digital transformation. In the context of the development of the digital economy in Vietnam is taking place strongly across industries and fields, requiring banks in Vietnam to have a transformation to a new business model. In this business model, it is necessary to integrate technology in operations and digitize business processes in the direction of automation and intelligence. Thereby, banks can perform activities of providing products and services on digital platforms, effectively exploiting data, thereby increasing experiences in business resolution and customer engagement. Besides, Internet of things has connect everything through internet, therefore risk management information system of Vietnam banks is also affected by IoTs and reliable internet data can help to enhance better RMIS in commercial banks. Generally, we want to emphasize effects of IoTs and digital transformation in banks operation and new business models.
