The system of pedagogical colleges in Vietnam has made important contributions to the education system in general and to the pedagogical system in particular during the 1980s and 1990s. This study reviews the studies conducted and implemented in recent times according to different trends, especially the contributions that these school systems have made to education as well as to the development of the system itself. The findings highlight the historic contributions of teacher colleges, and they also face challenges that must change to adapt to the new requirements of the pedagogy and education system. In addition, there are many issues that need to be researched and implemented not only related to the governance of each school but also associated with current systemic policy changes.
This study mainly aims to measure entrepreneurship performance in Vietnam at the national level through a new approach — the Global Entrepreneurship Development Index (GEDI). The GEDI consists of three sub-indices, including Entrepreneurial Attitudes, Entrepreneurial Abilities and Entrepreneurial Aspiration, which are divided into fourteen pillars and can be further subdivided into 28 variables. By analyzing these pillars and variables in comparison to two Southeast Asian developing economies — Thailand and Indonesia — which have similar cultural, economic and social characteristics, the study identifies the best and worst performing variables of the GEDI. The research results indicate that in Vietnam, nine bottlenecks of fourteen pillars are poorly performing with very low scores, in which the highest policy priority is given for four pillars, including risk acceptance, opportunity perception, internationalization and technology absorption. Finally, the Penalty for Bottleneck (PFB) methodology, which is considered as the policy application of the GEDI methodology and a simulation of "optimal" policy allocation are suggested to alleviate the weakest performing pillars, aiming to achieve the greatest improvement of entrepreneurship performance as well as reach the desired five-point increase in Vietnam's GEDI.
AbstractIn this study, we use a time-varying parameter vector autoregression in conjunction with the extended joint connectedness approach (TVPVAR-EJC) to examine the interrelationships among five variables, namely digitalization measured by the number of individuals using the Internet (% of the population), mobile cellular subscriptions (per 100 people), human capital index, CO2 emissions, and GDP, from 1996 to 2019 in Vietnam. Net total directional connectedness of digitalization and other variables suggests that it consistently acts as a net shock transmitter, whereas human capital was found to be a net receiver of corresponding shocks from 1997 to 2019. The emission of CO2 was a net critical receiver in 1998 but remained as a net transmitter for the rest of the period. Pairwise connectedness reveals that digitalization appeared as a net shock transmitter in connection with the human capital index and GDP. In the relationship with human capital, digitalization's role was critical.
Objectives: The purpose of this study was to identify the SNP sites and determine the BKV genotype circulating in kidney-transplant Vietnamese recipients based on the VP1 gene region. Methods: 344 samples were collected from post-kidney-transplant recipients at the 103 Vietnam Military Hospital to investigate the number of BKV infections. Positive samples with a sufficient virus concentration were analyzed by nested PCR in the VP1 region, sequencing detected genotyping and single-nucleotide polymorphism. Results: BKV infection was determined in 214 patients (62.2%), of whom 11 (5.1%) were diagnosed with BKV-associated nephropathy. Among the 90 BKV-I strains sequenced, 89 (98.88%) were strains of I/b-1 and 1 (1.12%) was strain I/b-2. The 60 BKV-IV strains had a greater diversity of subgroups, including 40% IV/a-1, 1.66% IV/a-2, 56.68% IV/c-1, and 1.16% IV/c-2. Additionally, of 11 cases diagnosed with BKVN, seven belonged to subgroup I/b-1 (63.6%) and four to subgroup IV/c-1 (36.4%). Moreover, 22 specific SNPs that were genotype I or IV were determined in this Vietnamese population. Specifically, at position 1745, for the Vietnamese BKV-IV strains, the SNP position (A→G) appeared in 57/60 samples (95%). This causes transformation of the amino acid N→S. This SNP site can enable detection of genotype IV in Vietnam. It represents a unique evolution pattern and mutation that has not been found in other international strains. Conclusion: The BKV-I genotype was more common than BKV-IV; however, mutations that occur on the VP1 typing region of BKV-IV strains were more frequent than in BKV-I strains.

Complications and surgical outcomes were noted. Prenatal care was carried out every 2 weeks post operation until birth. Newborn neurologic complications were assessed at birth, three months, and six months after birth using Denver II test and magnetic resonance imaging (MRI).Results: The mean gestational age at operation was 20.30 weeks. The average operation duration was 39.52 minutes. No complications of operation, such as bleeding or infection, were recorded. The mean gestational age at birth was 34.70 ± 4.33 weeks, with a mean duration of 12.97 ± 6.87 weeks between intervention and delivery. The survival rate of newborns after the operation was 90.48%. There were two stillbirths (9.52%) within seven days after the operation. No short-term neurological complications have been reported with follow-up of the newborn to 6 months after birth.Conclusion: Our study showed that fetoscopic laser ablation of selected fetal reduction surgery for treatment of special conditions of TTTS had no complications of operation, high neonatal survival result (90.48%), no short-term neurological complications. This should be considered for TTTS in cases of indication.Keywords: laser ablation, selective fetal reduction, twin-twin transfusion syndrome, new fetal medicine center
