Purpose The purpose of this paper is to explore the experiences of Tourism and Hospitality interns in Vietnam to identify dimensions of internship-related learning outcomes and factors influencing these learning outcomes. Design/methodology/approach In total, 12 in-depth interviews were conducted with 12 interns to identify the dimensions of internship-related learning outcomes. Following the interview, an online survey, which was designed based on the results of content analysis of the interviews, was used to collect data from 319 interns from ten Vietnamese universities. Exploratory factor analysis, descriptive statistical analysis, independent samples t-tests, and one-way ANOVA tests were used to find answers to the research issues. Findings Qualitative and quantitative analysis showed that from the students’ perspective, internships helped them consolidate the existing knowledge and skills, further develop relevant professional skills, shape their career paths, and change their learning attitudes and behaviors. The analysis also indicated that student engagement and the extent to which they are involved in tasks during the internships could influence the learning outcomes they gained from the internships. Research limitations/implications This study completely relied on students’ perceptions and ratings. Practical implications The study findings indicate that universities need to pay greater attention to student engagement. By encouraging collaboration between interns and their mentors and organizing activities for interns to utilize their knowledge, universities will improve students’ learning experience during the internship. Originality/value This mixed-method study expands our understanding about internship-related learning outcomes and influential factors using the perspectives of interns in a developing country. It has important implications for higher education institutions and students to improve the effectiveness of internships.

In the process of international integration, the State of Vietnam has always determined that implementing social security is both a goal and a driving force for sustainable development, maintaining socio-political stability. Over the years, Vietnam's social security has contributed to building a people-centered economy in Vietnam. Although the implementation of social security in Vietnam has achieved certain results with social progress, there are still some limitations that need to be overcome in the coming time to continue to improve social security towards a just and progressive society. The article analyzes the current situation (results and limitations) of the role of social security in social progress in Vietnam in the process of international integration; thereby contributing to providing more scientific bases for the decisions of the Government of Vietnam to improve the social security system to ensure social progress nowadays.

A total of 43 isolates of entomopathogenic nematodes of Vietnam were assessed on reproduction capacity in the last instar larvae of great wax moth (Galleria mellonella). The total yield of infective juveniles (IJs) on the Galleria mellonella were varied between indigenous isolates with significant different of multiplication. The amounts of IJs were produced in each Galleria from several thousands to hundreds thousands. These were shown a great difference of the reproduction capacity between indigenous isolates/species of entomopathogenic nematodes. In general, the multiplications of Steinernema isolates were lower than the multiplication of Heterorhabditis isolates. Among Steinernema isolates, however, the multiplications of some isolates were relatively low such as isolate S-DL9 (S. eapokense) with 4,378 ± 509 IJs, whereas other ones were relatively high such as S-TX1 (S. sangi) with 68,343 ± 8,942 IJs. These were also occurred significant difference between isolates within species that were particularly happened isolates of Heterorhabditis indica with average yields varieties from 18,900 IJs at H-PP16 to 233,500 ± 39,100 at H-NT3. The experiments showed the relationship between multiplication capacity of IJs and inoculation concentration and each isolate has an optimal inoculation concentration for highest multiplication. These data to be provided the important information for evaluation of potential isolates for biocontrol.
