Dental Public Health in Action: Utilising a telephone triage system to run an Urgent Dental Care Hub during the COVID-19 pandemic

This paper aims to explore the outcome of a telephone triage system used by different team members to run an Urgent Dental Care Hub (UDCH) during the first wave of the COVID-19 pandemic. It will also look at the adjustments made to the system because of the challenges faced. Data were collected from the telephone triage proforma and clinical notes of patients that were triaged from 2nd April to 10th June 2020. With 65% of telephone triaged and accepted patients receiving definitive treatment that alleviated the presenting complaint, the value of telephone triage is highlighted in streamlining an urgent dental care service during a viral pandemic. Public health competencies being illustrated: Dental public health intelligence, Developing and monitoring quality dental services.

Implementation of trinary logic in a polarization encoded optical shadow-casting scheme

The design of various multioutput trinary combinational logic units by a polarization encoded optical shadow-casting (POSC) technique is presented. The POSC modified algorithm is employed to design and implement these logic elements in a trinary number system with separate and simultaneous generation of outputs. A detailed solution of the POSC logic equations for a fixed source plane and a fixed decoding mask is given to obtain input pixel coding for a trinary half-adder, full adder, and subtractor.

Separate and simultaneous generation of multioutputs in a polarization-encoded optical shadow-casting scheme: design of half- and full adders and subtractors

A design algorithm for separate and simultaneous generation of multioutputs in a polarization-encoded optical shadow-casting (POSC) scheme is presented. The logic unit truth table is converted into POSC logic equations for true and false logic. These are then solved consistently to obtain source plane, input pixel, and the decoding mask characteristics. The algorithm is used to design binary half-adder and half-subtractor and full adder and full subtractor to carry out all operations with a fixed source plane and a fixed decoding mask. The results have been verified experimentally.

Design of optical decoders using a polarization-encoded optical shadow-casting scheme

We present the design of various decoders in the polarization-encoded optical shadow-casting scheme (POSC). A general algorithm is used to design these multioutput combinational logic units with separate and simultaneous generation of outputs. In particular, the design of a binary coded decimal (BCD) to an Octal decoder and a BCD to an Excess-3 converter is presented for a fixed source plane as well as a fixed decoding mask. The results have been verified experimentally.
