Summary: Working from home (WfH) is a promising practice for employees to balance work and personal life. The study found that a mismatch in WfH is associated with higher work-home interference and fatigue, but this mismatch did not predict changes in these outcomes after one year. A tailored WfH organizational policy that considers employees' needs could help them successfully combine work and private life.

Summary: This work presents the fabrication of a flexible and self-healing high-performance quasi-solid-state supercapacitor and analyzes its electrochemical performance and mechanical stability. The supercapacitor exhibits high capacitance and energy density, and maintains good performance even after multiple severing/healing cycles. Additionally, it shows excellent mechanical toughness, maintaining stability under various bending deformations. Therefore, this self-healing supercapacitor holds great application potential in portable/wearable electronics.

Summary: This study proposes a unified matrix-based model (UMP) to address flexible projects and a flexible structure generator (FSG) to analyze the effects of flexibility on topology and project demand-related indicators. The comparison of simulated and real-life databases shows that the interpretation range of the indicators is different, but considering flexibility can resolve this problem.

Summary: The study found that sleep disturbances, specifically difficulties in falling asleep and waking up early, but not sleep duration, were associated with higher CRP levels. No association was found with IL-6 or TNF alpha. Higher amounts of REM sleep were associated with lower CRP levels, suggesting that inflammation may link sleep and health in women.

Summary: The study focuses on how system resilience is enhanced by coordination performed in situ by a management team under variable circumstances in a neonatal intensive care unit. The results show a functional relationship between operational stress and a progression of adjustments in the actual situation, expressed through recurring patterns of adaptation. Coordinated efforts by managers in maintaining coherence in escalating problematic situations through teamwork are highlighted, with an emphasis on goal-setting, problem-solving, and circumventing technical systems' limitations.

Summary: This study aimed to describe challenges in self-management activities among people with multimorbidity during a 4-week post-discharge period. Patients with multimorbidity faced two major challenges in the first 4 weeks following hospital discharge: 'Managing a system-centered care' and 'Handling the burden of living with multiple illnesses at home post-discharge'. Therefore, self-management support post-discharge should not only assist patients with care coordination, but also meet their gradually shifting disease-related needs.

Summary: Sleep restriction therapy and sleep compression therapy have similar effects on sleep, but sleep restriction therapy may result in excessive sleepiness that affects treatment adherence. Sleep compression therapy may be a gentler alternative, but further investigation is needed to understand its mechanisms.

Summary: The increasing prevalence of chronic conditions and multimorbidity poses challenges to healthcare systems, and eHealth interventions are seen as a promising resource for supporting patients' self-management of chronic conditions. However, there is no consensus on how to design eHealth services to meet the complex needs of patients. This study applied a user-centered design approach in three phases to identify the needs of older adults and healthcare professionals, develop an eHealth service to address these needs, and test its feasibility and acceptance in a clinical setting.
