, 2010 2010-03今日働く母親の子育てや少子化といった問題は大きな社会問題である。歴史を振り返れば子育てに関して、日本だけでなく世界の多くの国が「乳母」という育児法を生み出している。日本では「乳母の制度」は王朝、貴族の時代、また武士の時代では権力と富を持つ者たちのためのものだったが、時代が下がるにつれて広がりを見せ、江戸時代には「御乳母日傘」で育つことは江戸っ子の条件でもあったという。貴族や武士の時代、乳母は権力者の傍にいたため、乳母の職は、自身や一族が権力を獲得する要石ともなった ...

Priority areas for conservation of Old World vultures
Conservation Biology, Volume 33, Issue 5, Page 1056-1065, October 2019., 2019 Abstract The prosperity and well‐being of human societies relies on healthy ecosystems and the services they provide. However, the biodiversity crisis is undermining ecosystems services and functions. Vultures are among the most imperiled taxonomic groups on Earth, yet they have a fundamental ecosystem function.

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

, 2022 为探讨延时时间及炮孔间距对岩石基坑爆破破碎效果的影响规律，依托大连地铁五号线虎滩公园站，建立岩体二维数值计算模型，通过连续-非连续数值模拟方法(CDEM)中的JWL爆炸模型及断裂能模型，对岩石基坑开展了爆破过程的数值模拟，并通过应力、振动速度、平均破碎尺寸、极限破碎尺寸、大块率及系统破裂度等指标进行综合分析。结果显示：模型监测点处以拉应力破坏为主导，延时35 ms时应力波叠加效果较好，引起的模型监测点峰值振速较小；随着延时的增大，岩石爆破效果逐渐变差，而当延时为25 ms时 ...

Wildlife Letters, Volume 3, Issue 3, Page 91-98, September 2025.The edge densities of cropland, developed land, and water bodies (panel a) predict the spatial probability of mammalian predation on wild turkeys (panel b) using Mahalanobis distance factor analysis in Quitman County, Mississippi, United States. The three habitat fragmentation variables are represented by three arrows, respectively.

Topical and transdermal botanical formulations of the Chinese pharmacopoeia—A review
Phytotherapy Research, Volume 38, Issue 9, Page 4716-4735, September 2024.Abstract In pharmaceutics, ingredients are classified as active ingredients and excipients. In topical/transdermal phytomedicines, an ingredient may serve both functions. Published information on these dual‐purpose ingredients and their pharmacological relevance is limited.

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,
