The gut-brain axis encompasses a bidirectional communication pathway between the gastrointestinal microbiota and the central nervous system. There is some evidence to suggest that probiotics may have a positive effect on cognitive function, but more research is needed before any definitive conclusions can be drawn. Inflammation-induced by lipopolysaccharide (LPS) may affect cognitive function. To confirm the effect of probiotics on oxidative stress induced by LPS, the relative expression of antioxidant factors was confirmed, and it was revealed that the administration of probiotics had a positive effect on the expression of antioxidant-related factors. After oral administration of probiotics to mice, an intentional inflammatory response was induced through LPS i.p., and the effect on cognition was confirmed by the Morris water maze test, nitric oxide (NO) assay, and interleukin (IL)-1β enzyme-linked immunosorbent assay performed. Experimental results, levels of NO and IL-1β in the blood of LPS i.p. mice were significantly decreased, and cognitive evaluation using the Morris water maze test showed significant values in the latency and target quadrant percentages in the group that received probiotics. This proves that intake of these probiotics improves cognitive impairment and memory loss through anti-inflammatory and antioxidant mechanisms.

Walking can have a positive impact on cognitive function in adolescents. This study aimed to compare the effects of walking with sneakers and barefoot on cognitive ability in adolescents. Fifty-nine adolescent male students were included in the study and assigned to the control (n = 20), sneaker (n = 19), and barefoot (n = 20) groups. The barefoot and sneakers group performed a 40-min walking exercise four times a week for 12 weeks during the morning physical activity time, while the control group performed self-study. Electroencephalogram (EEG) and brain activity variables were measured before and after the exercise program. The results showed that after 12 weeks, the barefoot group had a significant decrease in Gamma and H-beta waves and a significant increase in sensorimotor rhythm (SMR) and Alpha waves. Conversely, the control group showed a significant decrease in SMR waves and increase in Theta waves. The sneaker group showed a significant decrease in SMR waves alone. In an eyes-open resting state, the barefoot group showed a significant increase in H-beta, M-beta, SMR, and Alpha waves. The barefoot group also had a significant increase in cognitive speed and concentration and a significant decrease in brain stress. Taken together, barefoot walking can effectively enhance cognitive ability in adolescents, as demonstrated by the significant variation in EEG activity. This research highlights the potential benefits of barefoot walking as a simple and effective form of exercise for enhancing cognitive function in adolescents.

The purpose of this study was to investigate parenting stress changes in both continuous working and continuous non-working mothers after the birth of their first child and their relationships with the cognitive variables about child-rearing, using the 3rd Panel Study on Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE). The results revealed that the parenting stress of the non-working mothers was higher than the stress experienced by the working mothers. The increase in stress was only found both groups between the second year and the third year of childbirth. The total explanatory power of the knowledge, values and expectations regarding their children saw stress increase for the working mothers, but saw it decrease for the non-working mothers. Finally, the emotional value surrounding parenthood was the most powerful variable for both groups, with the exception of the non-working mothers' stress, as experienced in the first year.

The characteristic of the beta wave among the EEG waves corresponds to the stress area of human perception. The over-bandwidth of the stress is extracted by analyzing the beta-wave correlation between the low-bandwidth and high-bandwidth. We present a KMeans clustering analysis model for unsupervised machine learning to construct an analytical model for analyzing and extracting the beta-wave correlation. The proposed model classifies the beta wave region into clusters of similar regions and identifies anomalous waveforms in the corresponding clustering category. The abnormal group of waveform clusters and the normal category leaving region are discriminated from the stress risk group. Using this model, it is possible to discriminate the degree of stress of the cognitive state through the EEG waveform, and it is possible to manage and apply the cognitive state of the individual.

This study researched aspects of gender and grade related to the after-school happiness of lower grade elementary students and the correlation between the children's happiness and their stress and playfulness. Results of surveys and interviews of 124 lower grade elementary students who attended 4 after-school programs in Seoul showed that : (1) there were no gender differences in happiness but first graders were the happiest, then 2nd graders and the 3rd graders who were the least happy. (2) Children's happiness correlated negatively with stress. (3) There was no relationship between children's overall happiness and playfulness, but there was a negative correlation between happiness and playfulness under the sub-category of cognitive spontaneity. Results were discussed in relation to the Korean socio-cultural environment.
