Effect of perceived crowding on risk perception in leisure sports: An analysis based on Edward T Hall’s concept of ‘proxemics’
This study investigates the social distancing measures necessary for participants to safely engage in leisure sports activities and comply with social distancing requirements during epidemics. Based on crowding and risk perception in public spaces in this context of an epidemic, this investigation was conducted in terms of distance in Edward T. Hall’s concept of ‘proxemics’. The participants were males aged 20–65 who used spaces for leisure sport…

The Role of Science in the Policy Subsystem: An Application of the Advocacy Coalition Framework to Nanotechnology Regulation Policies
One of the key objectives of the advocacy coalition framework (ACF) is to clarify the role of science in policymaking. As such, scientists can help inform science and technology policy decisions by providing information on the risks and benefits of a technology. There is also high demand for scientists to take an active role in policy debates, and policymakers often rely on scientific experts to help them make decisions on regulations. However, f…
Variation in leisure sport conflicts and coping strategies depending on participation type and proximity during the Covid-19 pandemic
Introduction: New conflict types have arisen in leisure sports activities due to social regulations designed to address COVID-19. We analyze the differences in conflict-inducing factors and coping strategies across various types of leisure sports and levels of spatial proximity. Methods: Korean adults aged between 20 and 60 years, who had participated in leisure sports activities since the COVID-19 outbreak in January 2020, were surveyed, and 508…
A study on blood donor characteristics and preferred environment of South Koreans during the Covid-19 pandemic: A conjoint analysis
Objective: The COVID-19 pandemic has caused a decrease in the number of blood donors worldwide, posing a global problem. Therefore, this study investigates people who have continuously participated in blood donation during the COVID-19 pandemic and collects basic information as a reference for maintaining stable amounts of blood during future pandemics. Methods: The participants of this study were selected from the population of South Korea throu…
Examining the relationship between sleep quality and depressive symptoms in Korean women engaged in soccer during the coronavirus pandemic
Introduction: The COVID-19 pandemic has caused sudden changes to daily lives, such as self-isolation and social distancing, and has negatively affected sleep quality and patterns. The resulting psychological discomfort has caused many Korean women to experience depressive moods. Vigorous physical activity is considered effective in improving sleep quality and alleviating depressive symptoms. As a form of vigorous physical activity, soccer could b…
Identification of a Novel FAM83H Mutation and Management of Hypocalcified Amelogenesis Imperfecta in Early Childhood
Amelogenesis imperfecta (AI) is a heterogeneous group of rare genetic disorders affecting amelogenesis during dental development. Therefore, the molecular genetic etiology of AI can provide information about the nature and progress of the disease. To confirm the genetic etiology of AI in a Korean family with an autosomal dominant inheritance, pedigree and mutational analyses were performed. DNA was isolated from the participating family members a…
Management of Severely Aberrant Permanent First Molars in Molar Root–Incisor Malformation Patients: Case Series and a Guideline
Recently, a new type of dental anomaly, a molar-incisor malformation or molar root-incisor malformation (MRIM), was recognized. The disease phenotype is now relatively well characterized; however, its etiology and disease-mechanism need to be elucidated. The affected teeth do not respond well to conventional treatment because of severe malformation and an unusual root structure. In this study, we present the treatment of MRIM cases with the extra…
An Analysis of the Relationship between the Modified Theory of Planned Behavior and Leisure Rumination of Korean Employees
An increasing trend among employees has been to engage in leisure activities, which has been proven to be an effective method of overcoming work stress. As a result, employees are doing "Other Things" (i.e., non-work activities) as a way to relieve stress. Based on the existing studies on rumination, this study considered doing "Other Things" as a new concept of "leisure rumination" and identified its influence as a means to help employees recove…
Analysis of Korean Fencing Club Members’ Participation Intention Using the TPB Model
This study aims to investigate effects of three factors from the Theory of Planned Behavior (TPB)-attitude, subjective norms, and perceived behavioral control-on 233 fencing club members' intention to continue participation, while considering fencing's low popularity as a sport in Korea. This study analyzed data from members of fencing clubs in Seoul, Gyeonggi, Daegu, and Busan, using frequency analysis, exploratory factor analysis, reliability a…
Perceived Crowding and Risk Perception According to Leisure Activity Type during Covid-19 Using Spatial Proximity
This study aimed to investigate the difference in people's perceived crowding and risk perception during leisure activities using the criteria of spatial proximity during the COVID-19 pandemic. COVID-19 is a viral respiratory tract disease that poses an increasing risk of infection through person-to-person transmission in a confined space or close proximity to an infected person. It is thus crucial to maintain a sufficiently safe distance from ot…
Relationship between Phobic Anxiety in Work and Leisure Activity Situations, and Optimistic Bias Associated with Covid-19 among South Koreans
Because of the ongoing COVID-19 pandemic, the public is unable to maintain a proper balance between work and leisure, and an increase in community-based infections is causing severe phobic anxiety. Therefore, the present study investigated the differences in phobic anxiety between work and leisure activities according to optimistic bias among 533 South Korean citizens. Frequency analysis, descriptive statistical analysis, t -tests, and a one-way …
Correlation between Preventive Health Behaviors and Psycho-Social Health Based on the Leisure Activities of South Koreans in the Covid-19 Crisis
COVID-19 has caused unprecedented damage worldwide, and quarantine and lockdown measures have been undertaken globally. This study focused on the differences in preventive behaviors and psycho-social health of South Koreans, as people continue engaging in leisure activities under self-regulation without a lockdown measure imposed by the government. For the sample, the frame of the "2018 Population and Housing Census" in South Korea was applied, a…
Study on the Relationship between Leisure Activity Participation and Wearing a Mask among Koreans during Covid-19 Crisis: Using TPB Model
This study utilizes the Theory of Planned Behavior (TPB) variables-including "attitude," "subjective norms," and "perceived behavioral control"-to understand the relationship between mask-wearing behavior and physical/non-physical leisure activity participation in Koreans as well as the tendencies behind mask-wearing intentions within leisure activities. The measurement tools used attitude, subjective norms, control, and mask use intention factor…
Differences in Sense of Belonging, Pride, and Mental Health in the Daegu Metropolitan Region due to Covid-19: Comparison between the Presence and Absence of National Disaster Relief Fund
Korea's Daegu Metropolitan City once had the second highest rate of COVID-19 infection after Wuhan in China.
