This set of timely, important and distinguished twelve papers strengthens the transdisciplinary and novel linkages between the fields of human factor engineering, societal resilience, engineering decision analysis, and computational intelligence. These emerging information technologies are essential for sustainability in the era of the COVID-19 pandemic. The twelve papers are associated with the Honoulu, USA-based conference entitled "Recent Trends in Computer Science and Engineering (RTCSE)". We take a unified and holistic approach to the topic: Rather than isolating, stovepiping, and artificially separating the mathematical approaches from their 'real world' use, the dozen contributors to this unique 3C Technologia special issue have taken a unified and integrated perspective. The need for computational intelligence and societal resilience is growing. The 2021 tensions in Belarus preceded the 2022 uprising in Kazakhstan; the November 2015 terrorist attacks in Paris by the Islamic State and ongoing conflict in eastern Ukraine, Syria and Iraq are recent and important cases. On March 22, 2016, three coordinated nail bombings occurred in Belgium by the same Brussels-based Islamic State terror cell connected to the 2015 Paris terror attacks and other smaller-scale attacks against targets across Europe.
