The study analyzes images that have been cultivated by ancient cultural memories to become Korean cultural symbols, such as the model of women, the space containing the sediments of the times, and the way of life in daily activities and beliefs as a model of practice. Through that, the research wants to clarify the two major functions of these cultural symbols: shaping the national cultural identity and becoming a measure of valuation for contemporary perceptions of human dignity.

The incidence of eating disorders in dancers represents a complex health issue. Traditional research frameworks have failed to sufficiently elucidate this matter. Emerging theories on the gut-brain axis provide a potentially transformative perspective for understanding these disorders in dancers. Purpose: This review aims to explore the factors influencing eating disorders in dancers and to propose novel intervention strategies that integrate gut-brain axis theory with established multidimensional approaches.
