Synergistic Integration of Liquid Crystalline Ordering and Dynamic Networks for Ultrarobust Bismaleimide Vitrimers

Advanced Functional Materials, EarlyView.
A liquid‐crystalline bismaleimide vitrimer integrates local mesogenic organization with exchange‐active ester connectivity, achieving a glass‐transition temperature near 300°C while remaining reprocessable. Stress‐relaxation analysis and temperature‐dependent remolding reveal how segmental mobility, network rearrangement, and structural integrity ...

A Predictable Pattern Shift Schedule Model for Improving Nurses’ Shift Work

, 2022
우리나라 간호사의 낮은 인력 배치 수준과 열악한 교대근무 환경은 업무부담 및 직무스트레스를 높여 이직의도를 높일 뿐만 아니라 간호서비스의 질을 저하시켜 환자안전을 위협하고 있다. 본 연구는 임상간호사의 교대제 관련 선행연구, 근무일정표 분석, 간호사-전문가 그룹토론 및 패널 조사를 통하여 현장에서 적용 가능한 교대제 개선 모델을 개발하고 모델의 타당도를 평가하였다.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Direction of shift rotation among three-shift workers in relation to psychological health and work-family conflict

, 2004
Objectives The aim of the present study was to investigate whether the direction of shift rotation was related to the need for recovery, fatigue, sleep quality, work-family conflict, and leisure time among three-shift workers.Methods Data of 95 workers ...
