The coronavirus disease-2019 (COVID-19) pandemic has significantly impacted adolescent health, highlighting the need for effective health promotion strategies. This qualitative study analyzed adolescent health concerns during the pandemic and explored management strategies through focus group interviews (FGIs).FGIs were conducted on November 23 and 25, 2023, with six secondary school nutrition teachers, six educational supervisors, and six adolescent students. Semi-structured questions were used to explore five key domains: health behaviors, factors contributing to health problems, social support, perceived health beliefs, and health education. The FGI recordings were transcribed, and Braun and Clarke’s (2006) thematic analysis method was applied to classify and categorize the data. To ensure the reliability and validity of the study, all processes were meticulously documented, and member checking and triangulation were conducted. The analysis revealed that adolescents faced reduced physical activity, irregular eating habits, school lunch disruptions, social isolation, worsening obesity, mental health challenges, and decreased engagement in health-promoting behaviors. Nutrition teachers and educational supervisors emphasized the importance of the food environment in schools and policy support, whereas adolescent students. highlighted motivation and accessibility as the key factors for adopting healthy behaviors. Based on these findings, strengthening social support, expanding health education, and establishing a national support system are essential for improving adolescent health. This study has implications for policy and education to address adolescent health challenges during a pandemic and serves as a foundation for future health promotion strategies.

A standardized evaluation framework was developed for contract food service operations to analyze the priority of evaluation factors from the perspectives of contracting organizations (CO) and food service providers (FP). The Delphi technique and the Analytic Hierarchy Process (AHP) were used to identify and prioritize evaluation factors reflecting both perspectives. A three-round Delphi survey with 22 experts from academia and industry yielded seven evaluation areas and 46 indicators. Subsequently, an AHP survey was conducted with 40 experts (20 from CO and 20 from FP). The composite weights showed that “quality of menu and food” was rated highest by both parties (CO: 0.0699, FP: 0.0572), followed by “safe hygiene management” (CO: 0.0622, FP: 0.0366). Although CO prioritized “comfort and cleanliness of dining environment” (0.0344) and “meal distribution efficiency” (0.0341), FP emphasized “customer communication and satisfaction” (0.0316) and “food service operation management” (0.0302). By contrast, the lowest-ranked indicators included “carbon emissions management” (CO: 0.0120, FP: 0.0087), “ethical supply chain management” (CO: 0.0110, FP:0.0092), and “use of eco-friendly food materials” (CO: 0.0114, FP: 0.0101). Therefore, although traditional indicators remain dominant, sustainability and digitalization are still emerging in the evaluation framework. This study offers practical insights for enhancing objectivity and transparency in contract food service evaluation.The proposed framework integrates both perspectives, promoting mutual understanding and supporting the development of sustainable and efficient contract food service systems. Policy-level implications include aligning with public-sector evaluation models and environmental, social, and governance (ESG) mandates.

This study developed and validated a standardized scale to assess the adaptation of novice nutrition teachers to the teaching profession. A comprehensive literature review and a Delphi survey were conducted to identify the key adaptation factors, followed by a survey of 200 novice nutrition teachers across South Korea.Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to verify the reliability and validity of the scale. The final scale consisted of five factors: personal, interpersonal, organizational, community, and policy factors, having 56 items. Reliability analysis indicated high internal consistency (Cronbach’s α≥0.7 for all factors), and EFA confirmed that all items met the factor loading threshold (≥ 0.3). The CFA results revealed good model fit indices (CFI, TLI≥0.9, RMSEA≤0.1), confirming the structural validity of the scale. The socioecological scale developed in this study is an objective and practical tool for evaluating the adaptation levels of novice nutrition teachers and can be used as foundational data for developing support programs and policy development. Unlike previous studies that focused on individual teacher characteristics, this study applied a socioecological approach, incorporating organizational, social, and policy-related factors in addition to personal adaptation. Future research should extend the empirical application of this scale to diverse educational settings that verify its effectiveness, and develop comprehensive support strategies.

This study aimed to analyze the factors influencing the adaptation of novice nutrition teachers through big data analysis and to propose strategies for enhancing this process. Data were collected from internet portals using the keywords ‘novice nutrition teacher’ and ‘nutrition teacher’ from May 25, 2021, to May 25, 2024.Text mining techniques, including frequency analysis, semantic network analysis, and CONvergence of iterated CORrelations (CONCOR) analysis, were employed. Key terms such as ‘teacher’, ‘nutrition’, ‘career’, ‘school’, and ‘school meals’ exhibited high frequency and centrality, indicating the multifaceted roles of novice nutrition teachers and the need for increased support. Excessive workload and stress related to school meal management negatively impacted adaptation, highlighting the need for systematic management and capacity-building training programs. Mentoring and consulting systems played a crucial role in enhancing professional development, leading to better adaptation and higher job satisfaction. Additionally, stress and anxiety during the appointment preparation process were significant factors influencing adaptation, suggesting the need for improvements in the training curriculum at teacher education institutions. These findings provide valuable insights for developing policies to support the adaptation of novice nutrition teachers.
