In recent years, we have seen an explosion of wellness interventions and technology applications focused on human's wellness with the intention of helping people avoid needing medical care. Given the increasing emergence of wellness applications, there is a need to integrate existing diverse research endeavors and discuss key challenges and opportunities(More)
OBJECTIVES We examine the dynamics of gambling among young people aged 16-24 years, how prevalence rates of at-risk gambling and problem gambling change as adolescents enter young adulthood, and prevention and control strategies. METHODS A simple epidemiological model is created using ordinary nonlinear differential equations, and a threshold condition(More)
Our research aimed to conduct basic descriptions of temperamental traits and the level of state and trait anxiety of young male athletes, and to compare them by type of sports. Study participants were 277 athletes and 152 non-athletes who were all high school boys. The Korean version of the Temperament and Character Inventory (TCI) was used for checking(More)
Chlorpyrifos (CPF), an organophosphorus pesticide (OP), is one of the most widely used pesticides in the world. Subchronic exposures to CPF that do not cause cholinergic crisis are associated with problems in cognitive function (i.e., learning and memory deficits), but the biological mechanism(s) underlying this association remain speculative. To identify(More)
At low temperatures, the thermal conductivity of spin excitations in a magnetic insulator can exceed that of phonons. However, because they are charge neutral, the spin waves are not expected to display a thermal Hall effect. However, in the kagome lattice, theory predicts that the Berry curvature leads to a thermal Hall conductivity κ(xy). Here we report(More)
An ideal spin-% kagom6 lattice has been a long sought material. This system is characterized by strong magnetic frustration and is a likely candidate for a spin-liquid ground state. The spin-liquid state was originally proposed to exist in the parent compounds of the high temperature superconducting cuprates as originally proposed by Anderson. However, the(More)
