Comparative study of poverty dynamics and income structure: Pre and post COVID-19 impact on households with and without disabilities in South Korea.

Background: The COVID-19 pandemic, as an external shock, has affected the health and economic well-being of individuals. Vulnerable populations with limited resources have also been affected, exacerbating societal inequalities throughout the pandemic.

Objective: This study examined poverty dynamics in South Korea before and after the COVID-19 outbreak, focusing on changes in the poverty status and income structure of the population with and without disabilities.

Multilevel Factors Associated With Obesity Among South Korean Adolescents Before and During the COVID-19 Pandemic.

Coronavirus disease 2019 (COVID-19)-necessitated lockdowns and school closures have limited social interactions among adolescents, which result in unhealthy behaviors. This study compared the multilevel factors associated with obesity among adolescents in South Korea before and during the pandemic. We applied the social-ecological model and analyzed the 2019 and 2020 Korea Youth Risk Behavior Web-based Survey (KYRBS), including middle and high school students.

Consumers' participation in information-related activities on social media.

This study examined the relationship between consumers' characteristics and social media use, focusing on consumers' information-related activities such as creating content, sharing information, and providing feedback on information. The results showed that consumers' creating content, sharing information, and providing of feedback on information were affected by their digital literacy, need for cognition, and self-esteem. Information literacy and need for cognition had positive effects on engagement in these information-related activities, but self-esteem exerted a negative effect.

Designing the shape of supraparticles by controlling the apparent contact angle and contact line friction of droplets.

Surface-templated evaporation-driven supraparticle synthesis is a versatile method for supraparticle fabrication. A supraparticle is formed by drying droplet of a colloidal dispersion on liquid repellent surfaces, allowing precise control of the size and mean composition of the supraparticles. The crucial factor determining the morphology is the motion of the contact line of the dispersion droplet on the liquid repellent surface.

The influence of consumers' knowledge on their responses to genetically modified foods.

This study examined the influence of consumers' knowledge on their perceptions and purchase intentions toward genetically modified foods, and the implications of these consumer responses for sustainable development in the food industry. This study distinguished between objective and subjective knowledge and identified how an imbalance between the two knowledge types influenced consumers' attitudes and purchase intentions toward genetically modified foods. Results of a multinomial regression analysis showed that consumers with higher levels of education, income, and food involvement and more exposure to negative information about genetically modified foods tended to overestimate their actual knowledge level.

How does young women's weight perception affect their nutrient intake?: Korean young women's dietary consumption and nutritional deficiency.

We investigated the relationship between Korean young women's weight perception and nutritional deficiency to understand the effect of culturally fostered ideals of women's bodies on dietary life. We analyzed 585 participants' responses from the 2011 Korea National Health and Nutrition Examination Survey by using logistic regressions. Women who overestimated their weight were more likely to suffer from nutritional deficiency.

Study of acceleration of center of mass during sit-to-stand and stand-to-sit in patients with stroke.

[Purpose] The purpose of this study was to compare the center of mass during sit-to-stand and stand-to-sit activities in the timed up and go test between healthy subjects and patients with stroke. [Subjects and Methods] Thirty healthy participants and thirty patients with stroke volunteered for this study. Acceleration of the center of mass was measured using a wireless tri-axial accelerometer during sit-to-stand and stand-to-sit activities in the timed up and go test.
