This study aims to investigate the factors that contribute to the sustainable development of 334 Vietnamese construction and real estate companies listed on the Stock Exchange of Vietnam over a 5-year period from 2016 to 2020. By using regression analysis with the support of STATA software through examining the financial statements, which involves looking into crucial ratios including capital structure, profitability, firm size, accounts receivable management, and tangible assets investment, this study sheds light on whether these accounting indicators could help predict the construction and real estate companies growing potential in the future. Nevertheless, these ratios slightly contribute to the explanation of the change in revenue growth ratio, with a result of 1.6%, indicating that the value relevance of accounting information provides a modest and insignificant effect on investment decisions. This is understandable because the Vietnamese construction and real estate market still has many shortcomings in handling unexpected events, as well as the industry’s peculiarities related to major capital sources from bank loans. Based on this study, governmental authorities and business executives should plan appropriate risk management policies and measures to contribute to the sustainable development of construction and real estate companies.

The behavior of rPUf (polyurethane foam derived from bis(2-hydroxyethyl) terephthalate (BHET)recovered from post-consumer poly(ethylene terephthalate)-PET bottles) and cPUf (polyurethane foambased on a commercial polyol) were evaluated by comprehensive characterizations, and their thermalstabilities,flammabilities, and physical properties were compared. Without using aflame retardant, rPUfpassed the UL-94HB standard, whereas cPUf burned rapidly to the holding clamp. Various formulationsof rPUf and cPUf with established eco-friendlyfire retardants (FRs), including triphenyl phosphate,aluminum diethylphosphinate, and aluminum trihydroxide, exhibited notably higherfire resistance. Thedifferences between the experimental and calculated densities showed the effectiveness of the foamingprocess. A larger difference indicated that the FR improved the foaming process more. The BHET structurecontains an aromatic moiety that strongly enhanced the compressive strength and protected the rPUf/FRsfrom biodegradation, as evidenced by sorption isotherm experiments. For that reason, the rPUf/FRs couldbe used as building materials, especially under high humidity conditions. These are the advantages ofBHET over the commercial polyol for PUf preparation. Chemical recycle of post-consumer PET bottles toproduce high performance PUf could be applied on an industrial scale and then it creates the sustainablerecycling industry.

The synthetic path, optimized molecular structure and characteristics of DA were carried out using the calculations at the B3LYP/LanL2DZ level of theory. The experimental investigations have a good agreement with the theoretical results.

Background Primordial dwarfsm (PD) is a group of genetically heterogeneous disorders related to developmental disabilities occurring in the uterus and prolongs during all stages of life, resulting in short stature, facial deformities and abnormal brain. Objective To determine the exact cause of the disease in two Vietnamese patients priory diagnosed with PD by severe preand postnatal growth retardation with marked microcephaly and some bone abnormalities. Methods Whole-exome sequencing was performed for the two patients and mutations in genes related to PD were screened. Sanger sequencing was applied to examine the mutations in the patients of their families. Results Three novel mutations in the PCNT gene which have not been reported previously were identifed in the two patients. Of which, two frameshift mutations (p.Thr479Profs*6 and p.Glu2742Alafs*8) were detected in patient I and one stop-gained mutation (p.Gln1907*) was detected in the patient II. These mutations may result in a truncated PCNT protein, leading to an inactivated PACT domain corresponding to residue His3138–Trp3216 of PCNT protein. Therefore, the three mutations may cause a defciency of protein functional activity and result in the phenotypes of primordial dwarfsm in the two patients. Conclusions Clinical presentations in combination with genetic analyses supported an accurate diagnosis of the two patients with microcephalic osteodysplastic primordial dwarfsm type II (MOPD II). In addition, these results have important implications for prenatal genetic screening and genetic counseling for the families.

The goal of the study is to examine and assess how the factors of logistics service quality provided by logistics service providers influence customer loyalty and satisfaction in Vietnam. This study employs samples of the Kansei technique. The article’s data was gathered through an online survey of 388 distinct Vietnamese customers who used logistics services before and during the Covid-19 outbreak. After the data was obtained, it was evaluated using SmartPLS 3.0’s Cronbach’s Alpha test and structural equation model (SEM). Staff service quality, operational service quality, and technical service quality are the three factors that determine the quality of logistics services in the study. Out of the 10 proposed hypotheses, research findings show that five are acceptable. The Covid-19 Pandemic in Vietnam had a significant impact on all dimensions, but it had no effect on how satisfied customers were with the logistics service providers. Nevertheless, loyalty is considerably influenced by only one factor, which is customer satisfaction, and customer trust moderates the relationship between these two factors. As a consequence of that, several managerial implications have been proposed to help logistics service providers improve their services to attract and keep Vietnamese customers using their service in the long term.

Purpose: In the landscape of global challenges, the adoption of new technologies and the implementation of intellectual capital are seen as the main vehicles to enhance banking operations. Inspired by this issue, our study is to discover the effect of technological investments and intellectual capital on one of the most important dimensions of banking operations, namely deposit intermediation. Research design, data and methodology: To tackle this concern, we utilize the data of 12 banks from 2011 to 2020 in Vietnam, and perform the multivariate regression analysis as well as provide different robustness tests. Results: Our empirical analysis demonstrates that a surge in technological expenditures would foster distribution of deposit intermediation of banks. Also, the blend of technology spending and intellectual capital plays a key role in boosting this function of banks. Conclusions: The study would bring one of new evidence for bank managers and national authorities in Vietnam, where has undergone the completely reform period in banking system. Accordingly, technological innovation and intellectual capital should be taken into consideration when managers and regulators build business strategies and related policies. The findings are also useful for nations bearing a close resemblance to Vietnamese financial system.
