Over the past years the concept of human centred automation has received a lot of attention to achieve hybrid automation. A form of hybrid automation is taking benefit from the synergistic effect of human-robot collaboration. When used in assembly, the requirement of flexibility, adaptability and safety makes the design and redesign of human-robot collaborative (HRC) systems a complex and prone to error process. The use of time-based continuous simulations can offer safe virtual space for testing and validation thus easing the design of complex HRC systems. However, conventional simulations don't allow to experience the future production system as an end-user in an immersive environment. This paper explores the technological development in VR for design of human-centered production systems and develop a unified framework to combine human-robot simulation with VR. The simulation as an event-driven simulation helped in estimating the humanrobot cycle times, developing process plan, layout optimization and robot control program. The same simulation is used in VR to interact with the production equipment and particularly with the robot. Additionally, AWS Sumerian environment is used to create a virtual robot to assist VR user in the design process.

Pandemics cause chaotic situations in supply chains (SC) around the globe, which can lead towards survivability challenges. The ongoing COVID-19 pandemic is an unprecedented humanitarian crisis that has severely affected global business dynamics. Similar vulnerabilities have been caused by other outbreaks in the past. In these terms, prevention strategies against propagating disruption require vigilant goal conceptualization and roadmaps. In this respect, there is a need to explore supply chain operation management strategies to overcome the challenges that emerge due to COVID-19-like situations. Therefore, this review aimed at exploring these challenges and developing strategies for sustainability, and viability perspectives for SCs, through a structured literature review (SLR) approach. Moreover, this study investigated the impacts of previous epidemic outbreaks on SCs through a literature review, to identify the research objectives, methodological approaches, and implications for SCs. The study also explored the impact of epidemic outbreaks on the business environment, in terms of effective resource allocation, supply and demand disruptions, and transportation network optimization, through operations management techniques. Furthermore, this article structured a framework that emphasizes the integration of industry 4.0 technologies, resilience strategies, and sustainability to overcome SC challenges during pandemics. Finally, future research avenues were identified by including a research agenda for experts and practitioners to develop new pathways to get out of the crisis.

The circadian time structure of serum 25 (OH) vitamin D (25-OHD), calcium (Ca) and phosphorus (P) may prove to be helpful in prevention, efficacy and management of diabetes mellitus. Ten newly diagnosed patients with type-2 diabetes mellitus (6 men and 4 women), 30-65 years of age, and 10 age-matched clinically healthy volunteers (7 men and 3 women) were synchronized for one week with diurnal activity from about 06:00 to about 22:00 and nocturnal rest. Breakfast was served around 08:00, lunch around 13:30 and dinner around 20:00. Drugs/nutraceuticals known to affect the vitamin D-calcium metabolism and status were not taken. Blood samples were collected at 6-h intervals for 24 h under standardized, 24-h synchronized conditions. Serum 25-OHD, Ca, P, Ca-P product and Ca-P ratio were determined. A marked circadian variation was demonstrated for 25-OHD in healthy volunteers (p = 0.030) and of borderline statistical significance in the diabetic patients (p = 0.083) by population-mean cosinor analysis. Similarly, healthy volunteers showed borderline significance for serum Ca, P and Ca-P ratio. The circadian acrophase of Ca occurred later in the patients as compared to healthy controls. Mapping the circadian rhythm (an important component of the broader time structure or chronome, which includes a.o., trends with age and extra-circadian components) of vitamin D and calcium is needed for exploring their role as markers in the treatment and management of diabetic patients.
