Assessment of the level and risk of radioactive hazards in coastal sediments in northern Vietnam.

Radioactivity in coastal sediments in northern Vietnam was examined using data from five sediment cores to assess radioactivity concentrations and radiation risk indices. Radiation risk indices included radium equivalent activity (Raeq), the absorbed dose rate (ADR), the annual effective dose equivalent (AEDE), the activity utilization index (AUI), the external hazard index (Hex), the representative level gamma index (Iγr), and the annual gonadal effective dose rate (AGDE). The radioactivity concentrations of 40K, 232Th, 226Ra, 238U, and 137Cs were 567, 56.1, 35.1, 37.9, and 1.18 Bq/kg, respectively. The average concentrations of 40K, 232Th, 226Ra, and 238U were above the global average at five sites, except for 137Cs, which was low. The Raeq, Hex, and AUI indices were below the recommended values, while the AEDE, ADR, AGDE, and Iγr indices were above the recommended values. Moreover, 40K, 232Th, 226Ra, and 238U had significant impacts on the radiation hazard indices Raeq, ADR, AEDE, Iγr, AUI, Hex, and AGDE. There are three coastal sediment groups on the northern coast of Vietnam: Group 1 has a higher radioactivity and radiation risk index than Group 2 but a lower value than Group 3. Group 3 had the highest radioactivity and radiation risk index. The values of 40K, 232Th, 226Ra, and 238U and the ADR, AUI, Iγr, and AGDE indices in the sediment threaten the living environment.

Assessment of the distribution and ecological risks of heavy metals in coastal sediments in Vietnam's Mong Cai area.

Coastal sediments in the Mong Cai area were collected and analyzed for grain size, heavy metals, total organic carbon, and isotopes (210Pb, 226Ra, δ15N, δ13C) to assess sediment quality. The most common sediments were fine sand in surface sediment, very fine sand in core C1, and very coarse and coarse silt in core C2. The total organic carbon was highest in C2 next to the surface and lowest in C1, with content levels of 1.81%, 0.40%, and 0.31%, respectively. The chronology in C1 was 1877-2019 (142 years, 0-5 0 cm), with an average sedimentation rate of 0.71 cm/year. In C2, the chronology was 1944-2019 (75 years, 0-14 cm), with an average sedimentation rate of 0.27 cm/year. These δ13C and δ15N in the sediment reflect the source of the organic matter mix from the marine and terrigenous sediments. All studied heavy metals were lower than the ISQGs, with the exception of As in C1 and C2, which were higher. C1 showed a decline in As over time, while C2 As levels increased between 1996 and 2019. In terms of heavy metal pollution indexes, the geoaccumulation index (Igeo) showed that C1 and C2 were unpolluted to moderately polluted with As, with Li and Pb in C2; the enrichment factor (EF) was moderately enriched with As; the contamination factor (CF) was moderately contaminated (Pb, Cd, Fe, Mo, and Li) in C2 and C1 (Cd, As, Li) and considerably contaminated (As) in C2. The risk factor (ER) of As showed a moderate potential ecological risk in C2. The degree of contamination (CD) ranged from moderate to considerable (C1, C2), and the ecological risk (RI) was low. Although CD ranged from moderate (C1) to considerable (C2), most contamination was concentrated at the bottom of the cores. RI was low. The Mong Cai sediment quality does not currently affect the coastal area's ecosystem and fauna.

Association of Smoking Media Literacy with Vietnamese and South Korean Adolescents' Susceptibility to Smoking.

Studies on how smoking media literacy (SML) is associated with susceptibility to smoking among adolescents in South Korea and Vietnam are scarce. Thus, we examined the association of SML with susceptibility to smoking among adolescents in these countries to initiate a collaborative global health program. In total, 460 adolescents (Vietnam: 277, South Korea: 183) aged 15-18 completed an online cross-sectional survey. SML was measured using the 15-item SML scale. Susceptibility to smoking was measured by three questions on future smoking and if offered a cigarette by a friend. A multiple logistic regression model explored the association of SML with susceptibility to smoking. The study revealed that higher SML was significantly associated with lower susceptibility to smoking among Vietnamese, but not South Korean adolescents. Further studies to identify pathways between other factors associated with SML and susceptibility to smoking are needed to develop culture-specific intervention strategies for smoking prevention.

Prioritizing Training Needs of School Health Staff: The Example of Vietnam.

Competencies of school health staff (SHS) members, including school nurses, are crucial to improving child and adolescent health. In Vietnam, although SHS members are dispatched to schools, they have limited training opportunities. This study identified SHS members' training needs in a province of Vietnam. A cross-sectional, online survey was conducted with 204 SHS members. The performance and importance of SHS members' competencies were measured using 59-items and rated by a 5-point Likert scale. SHS members' training priorities were analyzed using the Borich Needs Assessment and the Locus for Focus model. Controlling infectious disease was the highest training priority while implementing health promotion programs was of relatively low priority. The high-priority training needs identified could be rendered mandatory in policy for continuing education of SHS members. Awareness of the importance of health promotion, which has been emphasized globally, should also be promoted via school health policy. These findings could guide development of future training programs for SHS members.

Developing Korean nursing students' global health competencies: A mixed methods approach to service learning in rural Vietnam.

BACKGROUND: Owing to globalization, there is a need for enhanced global health competencies among nursing students. In this context, global service learning programs are important opportunities for nursing students. OBJECTIVES: To explore the effect of a short-term service learning program in a developing country on the global health competencies of students attending a South Korean nursing college. DESIGN: A mixed methods design. SETTING: The Global Nursing Internship is a two-week pre-experience, eight-day on-site, and one-week post-experience program. PARTICIPANTS: The on-site activities involved 15 nursing students participating in global health activities in a rural Vietnamese community. METHODS: A self-reported questionnaire was used to assess changes in global health competencies in six domains, measured on a four-point Likert scale. Student satisfaction with each activity was measured on a five-point Likert scale. After completing the program, the participants wrote a self-reflection essay. The Wilcoxon signed rank test was used to analyze global health competencies, and content analysis was used to analyze participants' self-reflections. RESULTS: Regarding global health competencies, the overall mean score showed a significant increase at the post-program evaluation (Z = -3.41, p = .001). A pre-post-program comparison showed that the domain of "health care in low-resource settings" displayed the greatest increase in scores. The mean overall satisfaction with the program was high (mean = 4.31, standard deviation = 0.17). In the students' view, as expressed in their essays, their global health knowledge and attitude had improved. CONCLUSIONS: The program was useful in promoting global health competencies, empathy, and confidence and should be embedded among the essential requirements of nursing curricula. Suggestions are provided to develop an enhanced pre-experience program that could help students prepare better for on-site activities. As cultural competency is crucial for nurses, nursing educators should consider integrating similar global service learning programs into their existing nursing curricula.
