SJR Q2Journal of Exercise RehabilitationOA

Maternal infection is an important factor causing neonatal brain injury and later developmental disability. In the present study, we investigated the effects of treadmill exercise intensity on short-term memory, hippocampal neurogenesis, and expression of brain-derived neurotrophic factor (BDNF), and tyrosine kinase receptor B (TrkB) in the rats born of lipopolysaccharide (LPS)-exposed maternal rats. The rats were divided into six groups: control group, mild-intensity exercise group, moderate-in

A review of factors limiting physical activity among young children from low-income families
Seung Ho Chang, Ki-Jeong Kim
SJR Q2Journal of Exercise RehabilitationOA

Children need to participate in structured physical activities to avoid obesity and to engage in sports and games in the future. However, certain groups of our population have little access to enhance levels of physical activity. One such group is children from low-income families who are more likely to have less opportunity for participation in physical activity because of factors such as unsafe streets or limited access to playgrounds. According to the United States Department of Health and Hu

Ki-Jeong Kim, Hangil Lee, Jaehyun Choi, Young‐Sang Youn, Junghun Choi, Hankoo Lee, Tai‐Hee Kang, Min‐Cherl Jung, H. J. Shin, Hu‐Jong Lee, Se Hoon Kim, Bongsoo Kim
SJR Q1Advanced Materials

Scanning photoemission microscopy (SPEM) images of a graphene flake as well as the C 1s core level spectra for the mono- and multilayer graphene are measured. The samples with lateral dimensions on the micrometer scale are prepared on a SiO2 surface by direct exfoliation of crystalline graphite. Monolayer graphene is distinguished from the multilayer graphens through the chemical contrast images of SPEM.

Effects of smartphone texting on the visual perception and dynamic walking stability
Jongil Lim, Seung Ho Chang, Jihyun Lee, Ki-Jeong Kim
SJR Q2Journal of Exercise RehabilitationOA

Mobile phone use while walking can cause dual-task interference and increases safety risks by increasing attentional and cognitive demands. While the interference effect on cognitive function has been examined extensively, how perception of the environment and walking dynamics are affected by mobile phone use while walking is not well understood. The amount of visual information loss and its consequent impact on dynamic walking stability was examined in this study. Young adults (mean, 20.3 years

Treadmill exercise ameliorates depressive symptoms through increasing serotonin expression in postpartum depression rats
Eun‐Sang Ji, Jae Min Lee, Tae-Woon Kim, You-Mi Kim, Yeon Soo Kim, Ki-Jeong Kim
SJR Q2Journal of Exercise RehabilitationOA

Postpartum depression (PPD) is defined as the depressive symptoms that occur from the moment of delivery until 12 months after delivery. PPD symptoms are closely associated with reduced activity of the serotonergic system. Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in the pathogenesis of depression. Tryptophan hydroxylase (TPH) catalyzes the rate-limiting step of 5-HT biosynthesis in the serotonergic neurons. Exercise exerts anti-depressive effect on depression patients as wel

The effects of vision training, neck musculature strength, and reaction time on concussions in an athletic population
Justin Honda, Seung Ho Chang, Ki-Jeong Kim
SJR Q2Journal of Exercise RehabilitationOA

A concussion is a major concern across the athletic population. Prevention of concussions can lead to a decrease of 3.8 million concussions that occur annually in the United States. Vision training, increasing neck musculature strength and quick reaction times are thought to be ways to prevent concussions. The purpose of this study is to review the literature on vision training, neck musculature, and reaction time, and how these interventions can prevent concussions. Upon review of the literatur

Trends in exercise neuroscience: raising demand for brain fitness
Min Chul Lee, Kyeongho Byun, Ji‐Seok Kim, Hojun Lee, Ki-Jeong Kim
SJR Q2Journal of Exercise RehabilitationOA

Physical exercise is increasingly recognized as an important component in the neuroscience related field. What is the targeting of exercise and what accounts for the exercise's benefits observed in neuroscience? Several types of exercise have been studied in various fields across physiological, psychological, and biochemical experiments of neuroscience. However, more clarity is needed to unveil optimal exercise conditions such as frequency, intensity, type, and time. In this review, we briefly h

SJR Q1Nature CommunicationsOA

A key challenge in heterogeneous catalysis is to design atomically dispersed catalysts with high surface density, while simultaneously preventing agglomeration and promoting electronic metal-support interaction. Transition metal dichalcogenides (TMDs), such as platinum diselenide (PtSe2), offer a promising solution due to their unique structural and electronic properties. This study proposes a catalyst design that utilizes atomically dispersed transition metal species within the topmost layer of
