PURPOSE The COVID-19 pandemic led to rapid shifts in cancer survivorship care, including the widespread use of telehealth. Given the swift transition and limited data on preferences and experiences around telehealth, we surveyed oncology providers and post-treatment survivors to better understand experiences with the transition to telehealth. METHODS We distributed provider (MD, PA or NP, nurse, navigator, and social worker) and survivor surveys through the American College of Surgeons Commission on Cancer in mid-October 2020. Survivor surveys were also disseminated through patient advocacy organizations. We included questions on demographics, experiences with telehealth, and preferences for future telehealth utilization. RESULTS Among N = 607 providers and N = 539 cancer survivors, there was overwhelmingly more support from providers than from survivors for delivery of various types of survivorship care via telehealth and greater comfort with telehealth technologies. The only types of appointments deemed appropriate for survivorship care by both > 50% of providers and survivors were discussion of laboratory results or imaging, assessment and/or management of cancer treatment symptoms, nutrition counseling, and patient navigation support. Only a quarter of survivors reported increased access to health care services (25.5%), and 32.0% reported that they would use telehealth again. CONCLUSION Although there have been drastic changes in technological capabilities and billing reimbursement structures for telehealth, there are still concerns around delivery of a broad range of survivorship care services via telehealth, particularly from the patient perspective. Still, offering telehealth services, where endorsed by providers and if available and acceptable to cancer survivors, may provide more efficient and accessible care following the COVID-19 pandemic.

An increasing number of space agencies consider Moon exploration as a part of national and international space programs. Exploration plans include a distributed network of facilities on and around the Moon; opportunities for “driving force” projects based on the International Space Station program experience; and, on the whole, formation of the “Earth – low lunar orbit – Moon surface” payload traffic flow. The payload needs analysis shows that the cutting-edge Moon exploration program requires high quality navigation services (precise estimation of coordinates and velocity in near-real time). The subject of this paper is the issues of creating a navigation service based on the experience of the Russian segment of ISS and using the existing near-Earth GNSS systems as a navigation infrastructure.

The device designed is a navigation guide which will help the user with turn by turn directions. At the present time, use of smartphones for the navigation support has been increased and this in turn leads to risk of accident. The navi-guide device displays step by step direction on the OLED screen. This reduces the chances of mishaps and the increases the user focus. The navi-guide app has been developed for better user interface. The rider will have to just connect his phone to the device via bluetooth can safely reach his destination without any distractions with the aid of this device.

Conventional ice navigation through sea ice is manually operated by well-trained navigators, whose experiences are heavily relied upon to guarantee the ship's safety. Despite increasingly available ice data and information, little has been done to develop automatic ice navigation systems to better guide ships in sea ice. In this study firstly navigable sea areas for different types of ships were identified according to the navigation codes in northern regions. Secondly, three algorithms of path planning were adopted to automatically compute the safest-and-shortest ship routes based on the concepts of the Voronoi diagram, Visibility graph, and Visibility-Voronoi diagram, respectively. These algorithms and results were compared and evaluated in terms of different application scenarios. Results show that the Visibility-Voronoi approach seems to be the best viable solution in terms of computing performance and navigation safety. The work will provide a basis for further development towards an automatic ice navigation support system
