Stress is a natural state that emerges due to the dynamics of an individual's life. Children must learn how to effectively manage stress as part of their growth and development. Resolution is possible when children are exposed to stress and receive adequate support from their families. However, when stress is intense, frequent, protracted, or traumatic, as in cases of childhood abuse, it can become toxic and interfere with the development of the child's brain and body. This results in vulnerability, which can have detrimental effects on the child's overall physical, mental, and emotional health. This perspective discusses the impact of childhood maltreatment and toxic stress, drawing on insights gained during the COVID-19 pandemic. We aimed to shed light on the lessons learned from this unique and challenging period and how they inform our understanding of the effects of stress on children's well-being.

Purpose: Dining out at restaurants was limited during the COVID-19 period. In order to confirm the impact of COVID-19 on the chicken market, this study selected three chicken companies, Kyochon, BBQ, and BHC, and conducted financial statement analysis and regression analysis. Research design and methodology: Each company's financial statements were divided into before and after COVID-19, and the rate of change and financial ratio for each item were calculated to see if there were any significant changes, and the impact of COVID-19 on each company's sales was identified through regression analysis. Result: As a result of the study, the increase in sales and assets of each company continued, and the influence of COVID-19 could be confirmed through regression analysis. It can be inferred that COVID-19 indeed affected the expansion of the chicken market. Conclusion: Therefore, it was confirmed through this study that COVID-19 had a significant effect on the growth of the chicken market. While individual chicken small business owners are grappling with declining sales per outlet, the decline of commercial areas, and a surge in closures, the broader chicken franchise industry is witnessing a surge in demand and business expansion prompted by the pandemic.

With the ongoing coronavirus disease 2019 (COVID-19) pandemic, there is an increasing interest in the sequelae and care in recovered patients. Although the long-term sequelae of COVID-19 are still unknown, recently published reports suggest that some of the patients have persistent symptoms and show radiologic abnormalities after discharge. Herein, we present cases of four patients with previous COVID-19 infection manifesting pulmonary sequelae, including pulmonary fibrosis or organizing pneumonia pattern with persistent dyspnea after recovery.
