A Comparative Study of Nature Experiences and Emotional-Social Traits in Children from Urban and Rural Areas: A Case of Two Regions in Kanagawa Prefecture
本研究は,神奈川県の都市域(横浜)と中山間域(県西)に居住する子どもを対象に, 自然体験や自然・生物への関心と, 共生感・人間関係能力との関連を比較したものである。分析の結果, 地域ごとに自然との関わり方が異なり, それが子どもの感性や態度形成に多様な影響を与えていることが示唆された。都市域では家族単位の体験が共感力や挑戦意欲に関連し, 中山間域では継続的な自然体験が努力や主体性の育成に寄与していた。これらの知見は, 地域特性を踏まえた環境教育のあり方を考える上で重要な示唆を与えるものである
Phototunable Gelatin-Based Hydrogels as Cell Scaffolds for Modulating Cell Adhesion on Hydrogel Surfaces
The objective of this study was to design a light-responsive gelatin acrylate hydrogel for tunable cell−material interactions for tissue engineering applications. Hydrogels are widely used as cell scaffolds owing to their high water retention and cell encapsulation capabilities. Stereolithography techniques allow for the precise three-dimensional (3D) printing of hydrogels, creating complex tissue scaffold models. To enhance the limited tunabilities of 3D hydrogel cell scaffolds, photodegradable hydrogels that are responsive to light irradiation are known to enable controlled degradation and tunability, thereby promoting their application in tissue engineering. In this study, a photodegradable gelatin acrylate was synthesized by incorporating o-nitrobenzyl acrylate into the gelatin backbone, and the photodegradation behavior of the resulting gelatin acrylate hydrogel was evaluated using microsized patterned light irradiation to demonstrate the modulation of a limited area of the gelatin acrylate hydrogel surface. When human mesenchymal stem cells (hMSCs) were seeded on the light-irradiated hydrogel, cell spreading was enhanced by ca. 16−52%, whereas cell attachment decreased by ca. 25−40% compared with the unirradiated area of the hydrogel. These results suggested that the prepared gelatin acrylate hydrogel serves as a phototunable cell scaffold for fine-tuning biological microenvironments enabling postfabrication modulation that contributes to future regenerative medicine applications such as dynamic cell migration and vascular tissue modeling
