This study investigated changes in lifestyles and psychological anxiety among Koreans during the Coronavirus Disease 2019 (COVID-19) pandemic using the 2020 data from the nationwide Korean Community Health Survey. The study outcomes were psychological anxiety about the infection and death, due to COVID-19. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the relationship between psychological anxiety and lifestyle changes. During the COVID-19 pandemic, people who practiced healthy behaviors and followed social distancing and quarantine regulations experienced increased psychological anxiety for infection and death. Daily life changes during the COVID-19 pandemic were not associated with psychological anxiety. The result of this study can provide baseline measures for further study on psychological anxiety during re-infection of COVID-19 and future pandemics in Korea.

In marginalized ecosystem-dependent rural communities, access to ecosystem services plays a crucial role in achieving sustainable livelihoods. This study was conducted to find out the influence of various livelihood capital components on the access mechanism for forest-based Provisioning Services (PS) in some selected villages of the Gosaba Block on the fringes of the Sundarban. The contribution of the livelihood capitals to gain access to Provisioning Services (PS) was identified using factor analysis on 160 households, selected through cluster random sampling. The sustainability levels of livelihood capitals were analyzed using the Prescott-Allen method (2001). The natural, financial, social, and physical capitals were significantly below average, while the human capital was close to average. Enhancement of human, physical, financial, and social capital, ease in issuing Biometric Fisherman cards for entering forests, flexibility in borrowing loans, and ecotourism by involving local villagers must be encouraged to enhance forest-based provisioning services in the near future.

Innovation management is an organizational iterative process of seeking and selecting new opportunities and ideas, implementing them, and capturing value from the results obtained. In the defense sector, due to the increasing interdependence between military capabilities and technology, countries have adopted innovation management approaches to drive the modernization of their defense industrial bases, promoting the development and integration of advanced technologies. This study presents an original systematic literature review on innovation management approaches applied to defense in developing countries. After the phases of identification and screening, 62 documents both from academic and gray literature were analyzed and categorized into 22 distinct approaches. The advantages, disadvantages, contexts, and potential applications of each approach were discussed. The findings show that the appropriate use of these approaches can strengthen the innovation capacity and technological independence of late-industrializing countries, consolidating their position in the global defense landscape and ensuring their sovereignty and continuous technological progress.
