“…The article [8] proposes a layered system approach in order to organize airspace for UAM vehicles, depending on the vehicle type, level of autonomy, and altitude. Various ATM programs within German Aerospace Center (DLR) initiatives are discussed by the authors in [9]. The authors in [10] propose an assessment model for vehicleobstacle collision hazards.…”

To date, only a few studies have analyzed the clinical characteristics and genetic features of human granulocytic anaplasmosis (HGA) in South Korea. Thus, in this study, we investigated the clinical characteristics of HGA and methods used for clinical diagnosis. The clinical characteristics of patients with HGA were studied retrospectively. We reviewed the medical charts of 21 confirmed patients with HGA admitted to the Chosun University Hospital, located in Gwangju, South Korea. Twenty-one HGA patients visited the hospital 2–30 days (median 7 days) after the onset of symptoms. Fourteen patients (66.7%) had fever, which was alleviated 2 h (range 0–12.75 h) after starting treatment with doxycycline. Of the 18 patients who underwent peripheral blood (PB) smear test, only one (5.6%) had morulae. Additionally, only 4/17 patients (23.5%) had morulae in the PB smear reconducted after the confirmation of anaplasmosis. All 21 patients recovered without significant complications. As per results of the blood tests conducted at the time of admission, 7/21 (33.3%) and 5/21 (23.8%) patients showed at least 1:16 and 1:80 of IgM and IgG titers, respectively. Most HGA patients in Korea recovered without significant complications. The indirect immunofluorescence antibody diagnosis or morulae identification for HGA in this study had low sensitivity in the early stage of the disease.

Introducing Digital Air Traffic Controllers for Urban Air Mobility to Ensure Safe and Energy-efficient Flight Operations

Facing the continued growth of cities, the introduction of urban air mobility intends to reduce traffic congestion and improve the quality of services such as on-demand-transport, reduced travel times and increased connectivity. Nevertheless, its integration into existing air traffic flows remains one of the biggest challenges ahead, especially once controlled airspace overlaps with urban air mobility areas, such as at airport control zones. Here, air traffic control needs to coordinate among urban air mobility vehicles and conventional air traffic. In 2022, DLR conducted a human-in-the-loop simulation with ten air traffic controllers to validate previously developed workflows for that coordination task applied for Hamburg airport. The simulation results revealed that additional urban air mobility traffic increases controllers’ experienced workload up to 30% while slightly reducing their perceived situation awareness. Thus, a majority of controllers participating in the trials suggested to introduce an additional controller working position to exclusively control airtaxis and traffic following visual flight rules. This option is assessed as owning a high potential as cost intensive adaptions of regulations and procedures can be omitted. Nevertheless, the feasibility of this option is rather low due to the limited availability of endorsed human controllers. This study proposes a concept for a digital controller taking the responsibility of guidance for airtaxis under visual flight rules traffic (abbr. VFR) within a control zone. This digital controller is named “UAM digital controller” (abbr UDC) and based on algorithms calculating slots and trajectories which have been validated in previous DLR projects. The UDC coordinates with the human controller once a potential conflict is detected. Within the study, first the concept of the digital controller is defined, following existing work. As a second step, a theoretical evaluation based on an air traffic control task model and an operational concept for airtaxi integration will analyse the task load reduction for the human controller. Last but not least, the expected energy saving of flight operations by the digital controllers will be assessed.

“…The rapid growth of the UAV industry has created a psychological fear of the unknown among communities (Çetin et al, 2022). In this context, the integration of UAVs into existing systems under the UAM framework should consider not only technical aspects such as design, certification, operational aspects, and infrastructure requirements but also public acceptance (Schuchardt et al, 2023). Some research evaluating public acceptance of UAVs in urban logistics has shown a positive attitude toward the use of these vehicles (Melo et al, 2023).…”

This study aims to examine the public perception of Unmanned Aerial Vehicles (UAVs) in the context of Urban Air Mobility (UAM) and evaluate the widespread acceptance and applicability of this new technology. In this study, semi-structured interviews were conducted with 82 participants residing in the provinces of Istanbul and Ankara. The data obtained were analyzed using the thematic analysis method to categorize participants' views about UAVs in a specific structure. As a result of this analysis, participant views were categorized into three main themes: positive views, negative views, and neutral perspectives. Among the positive views, participants' expectations regarding the emergency use of UAVs stand out. In the negative views, concerns about the security and potential risks of UAVs took the lead, while mixed thoughts about the impact of UAVs on society, legal regulations, and technological development formed the neutral category.
