Management measures implemented at the West China Hospital may help prevent and contain COVID-19 and similar outbreaks

This article presents management processes for dealing with the novel coronavirus disease 2019 (COVID-19) outbreak at the West China Hospital of Sichuan University. From January to March 2020, the West China Hospital of Sichuan University established response structures and protocols, as well as integrated out-of-hospital resources, to deal with the COVID-19 outbreak. A total of 8,066 patients were screened and 345 COVID-19 patients were isolated for treatment. Hospital command systems, emergency management protocols, as well as process, space, and personnel management, and strengthening material reserves, and social responsibility strategies were implemented. Outbreak management aspects that required improvement included estimates of the anticipated number of cases, timely collection of patient information and feedback on the effect of outreach and online consultation methods.

Analysis of the Plan to Receive Emergency Fire Response Teams for Large-Scale Disasters in Japan

In the event of large-scale disasters requiring state-level responses in Korea, the Fire Commissioner of the National Fire Agency (NFA) mobilizes the fire-fighting forces from the cities or provinces of the entire country. Korea does not have a suitable system to receive support in disaster-affected cities or provinces. There is, however, a system to support disaster-ravaged cities or provinces in accordance with the fire-fighting force mobilization system under the Framework Act on Fire Services. Unlike Korea, Japan mobilizes registered emergency fire response teams (EFRTs) to address large-scale disasters. In addition, fire departments of all prefectures and municipalities have established plans to receive EFRTs to prepare for large-scale disasters within their jurisdictions. This study analyzes the plan to receive EFRTs when large-scale disasters occur and EFRTs are mobilized in disaster sites in Japan. The receiving plan includes the following: procedure for requesting EFRT mobilization; establishment of a fire support coordination headquarters within the emergency operations headquarters of prefectures; establishment of command headquarters and command support headquarters in municipalities; establishment of air command headquarters in the fire air corps of prefectures; and appointment of the heads of command for support units and command support teams. Additionally, the plan addresses the establishment of advance points, hutment places, fueling stations, command systems, communication operation systems, task assignment systems, and unit movement and withdrawal procedures.

The Data Acquisition System for the ATLAS Phase-II Tile Calorimeter Demonstrator

The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment at Large Hadron Collider (LHC). The TileCal readout system consists of about 10,000 channels. In 2025, the LHC will be upgraded leading into the High Luminosity LHC (HL-LHC). The HL-LHC will be capable to deliver an instantaneous luminosity up to seven times compared to the LHC nominal luminosity. The TileCal Phase-II upgrade will replace the majority of the on-detector and off-detector electronics using a new readout schema for the HL-LHC era. The on-detector electronics will digitize and transmit calorimeter signals to the off-detector electronics at the bunch crossing frequency. In the counting rooms, the off-detector electronics will store the digitized samples in pipelined buffers and compute reconstructed trigger objects for the first level of trigger. The TileCal Phase-II upgrade project has undertaken an extensive R&D program which includes the development of a Demonstrator module to evaluate the performance of the new clock and readout architecture for the HL-LHC. A Demonstrator module containing the upgrade on-detector readout electronics was built, tested during several test beam campaigns, and inserted into the ATLAS experiment. The Demonstrator module is operated and read out using a Tile PreProcessor (TilePPr) Demonstrator which enables backward compatibility with the present ATLAS Trigger and Data AcQuisition and the Timing, Trigger and Command systems. This contribution describes the components of the clock distribution and data acquisition system for the Demonstrator module, and its implementation in the ATLAS experiment.

Current Principles of Motor Control, with Special Reference to Vertebrate Locomotion

The vertebrate control of locomotion involves all levels of the nervous system from cortex to the spinal cord. Here, we aim to cover all main aspects of this complex behavior, from the operation of the microcircuits in the spinal cord to the systems and behavioral levels and extend from mammalian locomotion to the basic undulatory movements of lamprey and fish. The cellular basis of propulsion represents the core of the control system, and it involves the spinal central pattern generator networks (CPGs) controlling the timing of different muscles, the sensory compensation for perturbations, and the brain stem command systems controlling the level of activity of the CPGs and the speed of locomotion. The forebrain and in particular the basal ganglia are involved in determining which motor programs should be recruited at a given point of time and can both initiate and stop locomotor activity. The propulsive control system needs to be integrated with the postural control system to maintain body orientation. Moreover, the locomotor movements need to be steered so that the subject approaches the goal of the locomotor episode, or avoids colliding with elements in the environment or simply escapes at high speed. These different aspects will all be covered in the review.

LOGO ELEMENTS IN GEOGEBRA

The presented topic deserves attention because of its extreme usefulness, simplicity of its impact on the initial training in programming. This article discusses the basics of programming and features of work in the Logo environment, focused on the education and use of information technology, includes tools that allow you to display images in the style of commands of the Logo programming language. The inclusion of the elements of the Logo environment and the recursiveness underlying this language into interactive mathematical environments, for example, in GeoGebra, allow learners to create programs for solving a particular class of problems, which allows us to speak about the object approach when studying the content line of the school informatics course “Basics of algorithms and programming”, and the procedural programming approach characteristic of the Logo environment allows the formation of the corresponding features (logical, algorithmic thinking of students). A sufficiently easy to learn programming language in the Logo environment allows students to create programs and demonstrate unlimited possibilities for implementing mnemonics. The examples are series of simple examples of execution of command systems by the virtual executor “turtle” and the results demonstrating the creation of images with the help of a turtle are given.
