The dental, skeletal, and soft-tissue characteristics of a particular malocclusion can differ based on ethnicity, race, age, sex and geographical location with Class II malocclusion being one of the most prevalent malocclusions encountered in orthodontic clinical practice. The broad understanding of the characteristics of vertical skeletal and dental parameters in patients with Class II malocclusion can help clinicians to identify patterns and variations in the expression of this phenotype for better treatment outcomes. Hence, we compared the craniofacial characteristics of skeletal and dental Class II malocclusion traits from Indian and Vietnamese individuals to analyze the vertical skeletal and dental patterns in both population groups. The sample comprised of lateral cephalograms from 100 young adults with Class II malocclusion, of which fifty (25 males and 25 females) were from South India and the other 50 age- and sex-matched adults from Vietnam. The lateral cephalometric radiographs were digitized into anonymous image files and were traced and assessed for 16 vertical skeletal and dental parameters. The ANB angle was greater in males (+1.4 deg; p < 0.001) and females (+1.9 deg; p < 0.001) in the South Indian population. The Vietnamese males had a larger mandibular plane angle, articular angle, anterior facial height and lower anterior facial height compared to the Indian males. The Vietnamese females had larger mandibular plane and articular angles compared to the Indian females. The skeletal class II malocclusion was more severe in the South Indian compared to the Vietnamese adults. The Vietnamese sample showed a generalized tendency towards a more vertical skeletal growth pattern and in males this pattern seemed to be due to the dentoalveolar component. The Vietnamese females showed a tendency towards a vertical growth pattern, but without apparent contribution by the dentoalveolar component.

This paper analyses the effect of brand image, perceived quality, perceived uniqueness on loyalty of customers in the mobile telecom industry. The data for this study were gathered through face-to-face questionnaires that were distributed to target participants, who reported their consumption experience with mobile telecom services. The survey was conducted in Hanoi and Ho Chi Minh city with the sampling of 453 respondents. We used the Structured Equation Model to evaluate the suitability of the framework and examine the hypotheses. The results reveal that brand equity impacts directly customer satisfaction and has indirect effect on loyalty via customer satisfaction.

Professionalism has become one of the core competencies in medical education which will shape physicians’s behavior in the future to provide high-quality and patient-centered care services. Objectives: To assess the perceptions and attitudes of medical students regarding professionalism in health care. Methods: A cross-sectional descriptive study was carried out with 717 second-year and fifth-year medical students of Hue University of Medicine and Pharmacy, Hue University. Results: Students’ perception on professionalism was not high, at 3.85 out of 5 points. In which, “respect” was the domain having highest score and “communication skills” was the lowest recognition domain (4.15 and 3.54 out of 5, respectively). Preclinical students had higher perception than students having clinical experiences in all aspects of professionalism (p<0.05). Conclusion: Priority should be given to train professionalism and communication skills through the early clinical exposure program and hidden curriculum across all years of medical education program. Furthermore, the core aspects of professionalism are needed to be consistently identified and evaluated in the training program among medical universities in Vietnam

An efficient and practical method for the synthesis of pyrroles by Cu-catalyzed multicomponent reaction has been described. A range of highly functionalized pyrroles was prepared in good yields under solvent free condition.

The twentieth century is the century when new religious phenomena appear, which is recognized as a development trend of world religions. In our country, this term began to be popularized at the end of the twentieth century and the beginning of the twenty-first century. According to statistics of the Government Committee for Religious Affairs, the emergence of new religious phenomena has changed the religious life in our country in almost all aspects. The appearance and existence of “new religious phenomena” in the North partly reflected the change in the daily life of the people in the North on both positive and negative sides. This article focuses on studying the negative effects of “hot spots” related to religious phenomena in the North in recent years.
