Wellness Perception of South Korean Elementary School Students during the COVID-19 Endemic.

Unlabelled: This study aimed to analyze health management awareness among South Korean elementary school students in COVID-19 endemic areas.

Methods: Using convenience sampling, 675 South Korean elementary school students (age 11-12 years old) were selected as participants in July 2023. Data for the study were collected via online and offline surveys between July and August 2023.

Differences in Effort, Reward, Grit, Burnout, and Continuous Exercise Intention: Assessing the Effort-Reward Imbalance among Korean Athletes.

Although studies have shown that an imbalance between effort and reward in the workplace negatively affects an individual's physiological and mental health, few have looked at how this imbalance may affect the mental state of athletes. Therefore, this study aimed to evaluate the importance of the effort-reward imbalance (ERI) in athletes by examining whether psychological variables would differ depending on the ERI. To accomplish this, 795 registered collegiate athletes were recruited.

Mediating Effect of Sports Safety Awareness between Sports Activity Habits and the Intention to Complete Safety Education among Korean Adolescents.

Background: As the importance of safety during sports activities continues to gain emphasis socially, the interest in creating a culture of safety and safety education to support this is also increasing. However, no study has examined the willingness of adolescents to complete safety education voluntarily. To identify methods of building a culture of sports safety among adolescents, this study investigated the structural relationship among three related variables: sports activity habits, intention to complete safety education, and sports safety awareness of Korean adolescents.

An Analysis of Health Perceptions and Performance in Elementary Students in Korea during the ongoing COVID-19 Pandemic.

During the coronavirus disease 2019 (COVID-19) pandemic, social distancing guidelines changed lifestyles, including increased sedentary time, physical inactivity, and disrupted sleep patterns among children. The purpose of the present study is to analyze the health awareness (mental health, disease, physical activity, sleep, eating habit, and hygiene health management) of elementary school students during the COVID-19 pandemic, and use the importance-performance analysis (IPA) technique to identify gender differences in health perceptions. We collected data on 1006 students, which was analyzed using frequency analysis, reliability testing, independent sample t-tests, and importance-performance analysis (IPA).

Changes in Physical Fitness among Elementary and Middle School Students in Korea before and after COVID-19.

The present study aimed to analyze changes in health-related physical fitness among Korean elementary and middle school students before (2019) and after (2021) the COVID-19 pandemic. Data collection was completed by requesting the physical activity promotion system (PAPS) data from elementary and middle school students. This information is obtained annually by the Goyang Office of Education in Gyeonggi-do, Korea.

Factor Structure of the Korean Version of the Occupational Socialization of Beginning Physical Education Teachers Scale in the Context of the COVID-19 Pandemic and Its Relationship with Health Perception Education.

This study aimed to explore the factor structure of the Korean version of the occupational socialization of beginning physical education teachers scale, in the context of the COVID-19 pandemic, and to verify its relationship with health perception education. In October 2021, 257 Korean beginning physical education teachers were enrolled in this study. Data were analyzed using frequency analysis, exploratory factor analysis, confirmatory factor analysis, descriptive statistics, reliability analysis, and multiple regression analysis.

Effects of School-Based Physical Activity Programs on Health-Related Physical Fitness of Korean Adolescents: A Preliminary Study.

As adolescents spend the majority of their time focused on exams and assignments, they do not have sufficient time to engage in physical activity; this lack of physical activity is an important public health concern. This study aimed to investigate how school-based physical activity programs affect the health-related physical fitness of adolescents in the Republic of Korea. For this study, a total of 120 high school students participated in a school-based physical activity program that included badminton and table tennis for 15 weeks each (35 min/day, three times a week), with a total of 30 weeks for one academic year.

Development and Implementation of a "Music Beeps" Program to Promote Physical Fitness in Adolescents.

This study aimed to develop a physical education fitness program for adolescents to counteract the declining physical activity levels caused by the COVID-19 pandemic, as well as to investigate the program's effect. This mixed-methods study developed and implemented a five-component "Music Beeps" (MB) program to promote adolescents' physical fitness. A total of 240 students from two high schools in South Korea-divided into experimental and control groups-participated in 32 sessions over 16 weeks.

Efficacy of the optimal ablation index-targeted strategy for pulmonary vein isolation in patients with atrial fibrillation: the OPTIMUM study results.

Purpose: The ablation index (AI) is a recently developed marker for ablation lesion quality that incorporates contact force (CF), time, and power in a weighted formula. There is a paucity of information on whether AI-guided pulmonary vein isolation (PVI) could improve the outcome in patients with atrial fibrillation (AF). We evaluated the optimal AI threshold for avoiding acute pulmonary vein reconnection (PVR), and to compare the efficacy of optimal AI-targeted PVI with that of conventional CF-guided PVI.

Association of metabolic syndrome and chronic kidney disease with atrial fibrillation: A nationwide population-based study in Korea.

Aims: Metabolic syndrome (MetS) and chronic kidney disease (CKD) are significant risk factors for incident atrial fibrillation (AF). Few studies have reported the synergistic effect of MetS and CKD on development of AF. We investigated the individual and synergistic effects of MetS and CKD on the risk of incident AF.
