The findings of this review of reviews suggest that some personal and environmental factors were related with participation in physical activity. However, an association of various factors with physical activity could not be established because of the lack of primary studies to build up the organized evidence. More studies with a prospective design should be conducted to understand the potential causes for physical activity.

Patients with PAO due to RA show different clinical manifestations when compared with those without PAO and have neutrophil-dominant airway inflammation.

Using two nationally representative datasets, this paper examines how the imposition of a curfew on private cram schools affects the consumption of private tutoring services as well as the time use patterns of Korean high school students. To identify the impact of the curfew, this study capitalizes on inter-city/province variation in private cram school regulatory ordinances and estimates a difference-in-differences estimator between the years of 2009 and 2012. The findings indicate that the cur

The group with high risk of diabetes showed healthy behaviors, but they did not have a normal body composition. Policies and campaigns targeting integrated health behaviors will be needed to reduce the burden of diseases and improve public health.

A CP dose of > 15 mg/kg is effective for reducing the severity of PQ-induced lung injury as determined by histological and micro-CT tissue examination, possibly by modulating antioxidant enzyme and TGF-β1 levels.

Sex-specific trends in alcohol consumption were influenced by demographic, behavioral, and perceived health-related factors. The findings will help improve the understanding of alcohol-related problems and provide evidence for establishing country-specific policies and campaigns in Korea.

We investigated the role of common genetic variation in immune-related genes on breast cancer disease-free survival (DFS) in Korean women. 107 breast cancer patients of the Seoul Breast Cancer Study (SEBCS) were selected for this study. A total of 2,432 tag single nucleotide polymorphisms (SNPs) in 283 immune-related genes were genotyped with the GoldenGate Oligonucleotide pool assay (OPA). A multivariate Cox-proportional hazard model and polygenic risk score model were used to estimate the effe

HPA reduced the risks of mortality in middle-aged Korean adults and could even decrease the risk of death in those who did not participate in LTPA.

As the divorce rate in South Korea increases, an increasing proportion of children are growing up in single-parent families. Given the limited public support and disadvantages for women in the labor market, it is expected that single parents in Korea, single mothers in particular, are more likely to use family ties to mitigate economic and social difficulties, including the option to live with their parents. We assessed the living arrangements of single parents and their children with respect to

The unemployment rate among youths (age 20–29) in South Korea has increased sharply from 6.6 percent in 2002 to 9.8 percent in 2016. At the same time, the college entrance rate remains around 70 percent, and skill mismatch among college goers is a critical policy concern. Little attention has been paid to temporal change in labor market outcomes among college graduates or to the kinds of graduates who are particularly vulnerable to labor market uncertainty. We investigate how labor market experi

We test the effect of school choice on studentsʼ academic performance by exploiting the change in high school assignment program in Seoul, Korea from within-district randomization to open enrollment. Employing difference-in-differences methodology on administrative data of high school studentsʼ National Assessment of Educational Achievement test scores, we find no evidence that enhanced school choice improved average test scores in Seoul. However, we find differential effects across school types

Specific characteristics of PA pre- and post-diagnosis may influence the survival of cancer patients.

This study examines the effects of peer victimization by verbal, physical, and relational bullying on Korean adolescents’ self-worth, disconnect to peers, school engagement, and academic achievement. A two-year longitudinal survey on 3,266 sixth-graders attending school in Seoul, Korea was used. Multivariate regression results controlling for socio-demographic characteristics as well as initial levels of outcome indicated that youth bullied by their peers experienced greater difficulties than no

Past studies of human rights discourse have centralized civil and political rights over other types of rights, and have thus yielded a biased understanding of how human rights have evolved. This scholarship has also neglected the role of the political slant of reporting agencies in framing topics and issues covering human rights. This study offers new theoretical and analytical solutions to such limits by analyzing a newly compiled data corpus comprising 101,689 South Korean newspaper articles—b
