Korean Children’s YouTube Use and Social Skills: A Linkage Analysis with Negative Interactions in Favorite YouTube Content
Given the popularity of YouTube viewing among young children, we studied the relations between young children’s YouTube viewing time and exposure to negative interactions within reported favorite YouTube content on their self-regulation, anxiety, and social skills. Through analysis of data collected from 341 South Korean parents (child ages 4–6), we found that child YouTube viewing time was associated with poorer child self-regulation. We also fo…
Are your defense mechanisms harming you? The role of psychological defenses in social media comparison and adolescent self-esteem
A content analysis of cognitive, emotional, and social development in popular kids’ YouTube
With the explosive growth in time spent on YouTube by babies and toddlers, it’s important to analyze what they’re watching on YouTube. Indexes that evaluate the contents of YouTube channels for infants and toddlers have been developed, but since those were evaluation-based indexes of educators and parents, it is difficult to find out what content children are watching. In this study, the YouTube content that infants mainly watch was content analy…
Introduction of Supervisor-Type Pediatric Hospitalists in a Tertiary Children’s Hospital: Experiences in a Hematology/Oncology Ward
(1) Background: Hospitalists are healthcare providers who focus on hospitalized patients, but research on the roles of pediatric hospitalists is lacking. This study investigates the role of a supervisor-type hospitalist in a pediatric hematology/oncology ward at a tertiary children's hospital, assessing the impact on satisfaction levels among patient caregivers, resident physicians, and nurses. (2) Methods: A retrospective analysis and online sur…
Associations between Sclerostin and Anthropometric and Metabolic Parameters in Children and Adolescents
(1) Background: Bone plays an important role in the regulation of the systemic glucose and energy metabolism. Sclerostin, secreted by osteocytes, is an inhibitor of the Wnt/β-catenin bone metabolic pathway, and is involved in osteoporosis and metabolic disease. The aim of this study was to investigate the relationship between sclerostin and anthropometric and metabolic parameters in children and adolescents with obesity or who are overweight. (2)…
Explicit and implicit attitudes toward people with Covid-19: Need for community mental health services
During the course of the COVID-19 pandemic, social stigmatization of people who have been infected with the virus has been observed. This study measured the degree of social stigma by examining implicit and explicit attitudes toward people with COVID-19. Explicit attitudes were measured through self-reporting, taking into account the three components of behavior, cognition, and emotion, and we used the Single-Category Implicit Association Test to…
Influencing Myself: Self-Reinforcement Through Online Political Expression
Over the past decade, various online communication platforms have empowered citizens to express themselves politically. Although the political impact of online citizen expression has drawn considerable attention, research has largely focused on whether and how citizen-generated messages influence the public as an information alternative to traditional news outlets. The present study aims to provide a new perspective on understanding citizen expre…
Cross-Cutting Effects of Hypertext Navigation on the Convergence of Attitudes
This study explores the navigation patterns of users reading hypertext-linked online news articles about a controversial issue. With the theoretical frameworks of selective exposure and cross-cutting exposure, the study examined the effects of individuals’ attitudes on their navigation patterns and consequent attitude changes after the news exposure. We asked 130 participants to read positive or negative news articles about the Korea–U.S. free tr…
Effects of Image–Issue and Positive–Negative Scene Orders in Broadcast News
The effects of image–issue scene orders and positive–negative scene orders in a broadcast news story on viewers’ memory, attitudes, and voting intention are examined. The 2 different orders of image–issue and positive–negative scenes are independent variables, whereas free recall, recognition memory, attitudes toward candidates, and voting intention are the dependent variables for this study. An experiment with broadcast news stories about politi…
The Role of a Scene in Framing a Story: An Analysis of a Scene's Position, Length, and Proportion
A scene is proposed as the unit of analysis in broadcast news studies as a way to measure a more accurate representation of perspectives and arguments of a story. Based on film studies, a scene is defined as a unit that represents continuity in time, place, character, ideas, or themes in a news story. The role of a scene in a news story is analyzed by examining how the position, length, and proportion of a scene frame and valence are related to s…
