Abstract Background: The restriction and quarantine due to Covid-19 has led to unprecedented disruptions in the lives of women and children. Due to the increase in violence against women and children, the using of e-health has been considered to provide supportive care in this area. The purpose of this paper is developing comprehensive evidence-based framework of e-health intervention to response women and child violence.Methods: The methodology of this study was based on a two-stage which included literature review at the beginning. In first step a comprehensive review performed for extracting studies that survey the effectiveness of information technology in managing violence against women and child. Researches extracted appropriate articles and summarized important component. The review steps included set questions, search strategy and inclusion/exclusion criteria. The framework was defined based on the literature review and social-ecological model (SEM).Result: The finalized framework for application IT-based interventions in the management of violence against women and children presented in 4 dimension including individual, relationship, community and societal. The first and second levels of this model include 4 dimensions of SEM and 6 types of violence. The third level includes suggestions for managing violence and the fourth level includes IT-based interventions. Surveillance system and information resource system can be used for monitoringConclusion: During Covid-19, domestic violence and economic pressures increased, and vulnerable women and children were at greater risk. It is critical to identify people at risk, to follow and monitor them, to raise the awareness and knowledge of these people, and to empower and provide psychosocial support to these people during this period. In this study, a comprehensive review of IT-based interventions was presented and finally an international framework in this field was described.

In the light of the current changing global scenarios, green infrastructure is obtaining increasing relevance in planning policies, especially due to its ecological, environmental and social components which contribute to pursuing sustainable and resilient planning and designing of cities and territories. The issue of green infrastructure is framed within the conceptual contexts of sustainability and resilience, which are described through the analysis of their common aspects and differences with a particular focus on planning elements. In particular, the paper uses two distinct case studies of green infrastructure as representative: the green infrastructure of the Region Languedoc-Roussillon in France and the one of the Province of Turin in Italy. The analysis of two case studies focuses on the evaluation process carried on about the social-ecological system and describes the methodologies and the social-ecological indicators used to define the green infrastructure network. We related these indicators to their possible contribution to the measurement of sustainability and resilience. The analysis of this relationship led us to outline some conclusive considerations on the complex role of the design of green infrastructure with reference to sustainability and resilience.

Rotor Model

Nonsynchronous rotating damping, i.e. energy dissipations occurring in elements rotating at a speed different from the spin speed of a rotor, can have substantial effects on the dynamic behaviour and above all on the stability of rotating systems.The free whirling and unbalance response for systems with nonsynchronous damping are studied using Jeffcott rotor model. The system parameters affecting stability are identified and the threshold of instability is computed. A general model for a multi-degrees of freedom model for a general isotropic machine is then presented. The possibility of synthesizing nonsynchronous rotating and nonrotating damping using rotor- and stator-fixed active dampers is then discussed for the general case of rotors with many degrees of freedom.
