The molecular dynamic simulation method is usually used to analyse microscopic fluid fields. To use this method in engineering problems with real scales of molecules needs more time and greater computer power than we have now. To overcome these limitations, the expansion method using dimensionless and similarity of physical quantities of molecules is studied and introduced for the engineering scale fluid dynamics.

가시귀진드기(Otobius megnini (Dugès)) (거미강: 참진드기목: 참진드기과)는 전 세계적으로 분포하며, 말에게 감염 시 신경근육장애와 연관 이 있다는 보고가 있으며, 국내에서는 1989년 서울의 경주마에서 최초로 보고된 이후 추가적인 보고는 없었다. 본 연구를 통하여 2023년 부산과 2024년 용인의 말에서 총 47개체가 채집되었으며, 형태학적 및 분자학적 동정을 실시한 결과 해당 개체들은 모두 O. megnini로 동정되었다. 채집된 O. megnini의 COX1 및 16S rRNA 유전자 분석 결과, 해외 분리주와 99.5–100%의 높은 상동성을 보였다. 모든 시료는 Coxiella burnetii, Babesia spp., Anaplasma spp., Ehrlichia spp., Borrelia spp., 중증 열성 혈소판 감소 증후군 바이러스(SFTSV) 검사에서 음성이었다. 본 연구는 1989년 이 후 처음으로 국내에서 O. megnini를 재발견하였으며 이 종에 대한 국내 최초의 분자적 특성을 제시하였다.

This review summarizes recent insights into the effects of foods and natural products on brain function, focusing on neuron-glia interactions and the Gut-Brain Axis. Bioactive compounds such as polyphenols, omega-3 fatty acids, curcumin, and ginsenosides exert neuroprotective effects by attenuating oxidative stress and neuroinflammation through activation of the Nrf2/ARE signaling pathway and suppression of NF-?B-mediated inflammatory cascades. They also enhance synaptic plasticity via the CREB-BDNF pathway, improving learning and memory function. Fermented foods and microbiota-related metabolites, particularly short-chain fatty acids (SCFAs), modulate the Gut-Brain Axis, leading to increased hippocampal BDNF expression and emotional stability. Traditional Korean fermented foods and marine-based dietary components further contribute to the regulation of neuron-glia networks, providing a scientific rationale for the neurofunctional benefits embedded in Korean dietary culture. This review highlights that food-derived bioactive components act not only as nutrients but also as neuromodulatory agents maintaining brain homeostasis. Future perspectives emphasize integrating molecular neuroscience with food culture research to advance the emerging field of food neuroscience and promote functional food innovation grounded in traditional dietary wisdom.
